Acupuncture and Moxibustion in June 2008. Permission was granted to reprint this translated article in the journal of

Medical Acupuncture. This is part of our cooperative Center Of Excellence effort between the University of Beijing, School

of Medicine and Moxibustion, and the journal Medical Acupuncture. This was a large and tedious effort on behalf of our

Chinese colleagues to study the actual indications and use of 33 acupuncture points. It reflects a most high level of co-

ordination and effort to gather the data at many university centers and analyze it into the Chinese Compendium of Acu-

points. Most important question: were the ancient descriptions of these points accurate when analyzed in with our mod-

ern technological evaluations? This is what our colleagues set out to accomplish in a most labor-intensive and involved

scientific manner. It is interesting to note that the style of this Chinese paper reflects a conception of research that devi-

ates from the West. It is important that the reader be willing to accept that scientific methodologies are different and

influenced by culture. We should be flexible to appreciate and to respect our Chinese colleagues contributions. Of course,

there is no room for poor scientific research. All of us would agree. I apologize for any errors and inaccuracies that are

a result of the translation effort.

ABSTRACT

Objectives: To verify the indications of 33 acupoints scientifically and provide definite clinical data for the in-

dications of acupoints (which will be recorded in the Compendium of Acupoints of China).

Methods: Randomized controlled clinical trials (RCTs) in multiple centers were performed.

Results: Among a total of 52 studies, results of 40 studies showed the acupuncture-moxibustion (acumoxa)

groups had better therapeutic effects than those in control groups. Results of 11 studies showed the acumoxa

groups had similar therapeutic effects to those in control groups. Results of 1 study showed the control group

had better therapeutic effects than that in acumoxa group.

Conclusions: Needling a single acupoint to treat diseases and symptoms may have different therapeutic effects.

INTRODUCTION

THE PROJECT OF Compendium of Acupoints of China wasestablished in 2003 with funding from the State Ad-ministration of Traditional Chinese Medicine of China, in-

cluding 2 parts of compiling the Compendium of Acupoints,

and clinical studies on the indications of acupoints.

METHODS

Totally, there were 59 studies, which consisted of clini-

cal sub-projects, 52 of them applied multi-center, random-

ized, and controlled design. Those 52 studies have been con-

ducted for over 4 years; 540 acupuncture physicians and

related staff from 116 hospitals in 19 provinces, municipal-

ities, and autonomous regions took part in the 52 studies.

The indications of 33 points were studied by randomized

controlled trails (RCTs) in multiple centers. Thus, certain

definite clinical data for the indications of certain acupoints

were provided (which will be recorded in the Compendiumof Acupoints of China).

Thirty-three commonly used acupoints and 36 diseases

and symptoms were involved in the studies, including 30

meridian acupoints and 3 extraordinary acupoints, covering

12 meridians (except for the Lung Meridian of Hand-Taiyin

and the Liver Meridian of Foot-Jueyin). The main contents

of those studies follow.

Participants

The 33 acupoints included: LI 4, LI 11, LI 15; ST 11,

ST 25, ST 36, ST 37, ST 38, ST 40; SP 6, SP 8; HT 7;

SI 1, SI 3; BL 13, BL 17, BL 35; KI 6; PC 6; SJ 6; GB 20,GB 24, GB 30, GB 40; CV 3, CV 12, CV 17; GV 14,

GV 20, GV 26; Sifeng (EX-UE10), Sishencong (EX-HN1),

and Taiyang (EX-HN5).

The 36 diseases and symptoms studied in the projects were:

the common cold, chronic pharyngitis, asthma in the respira-

tory system; hyperlipidemia, premature heartbeat, hyperten-

sion, shock in the cardiovascular system; adverse reaction in

the stomach and intestines, chronic cholecystitis, peptic ulcer,

constipation, intestinal irritation syndrome, ulcerous colitis,

infantile anorexia and infantile malnutrition in the digestive

system; urinary retention, chronic prostate hyperplasia, re-

ducing clinical symptoms, insufficient lactation, lack of con-

traction of uterus, female urethral syndrome, primary dys-

menorrhea and menopause syndrome in the genito-urinary

system; goiter, side effects of chemotherapy and radio ther-

apy in malignant tumor in the endocrine and immunity sys-

tems; depression due to stroke, insomnia, dysfunction of mo-

bility after cerebral thrombosis, primary sciatica, migraine,

central dizziness in psychological and nerve systems; peri-

arthritis of shoulder, acute sprain of lumbar in the motor sys-

tem, chronic urticaria, toothache, and high fever.

All 52 studies consisted of RCTs in multiple centers with

follow-up. Electroacupuncture was applied in the treatment

groups of 41 studies; regular acupuncture was applied in the

treatment groups of 10 studies; moxibustion was used in the

treatment group of 1 study. The studies were conducted in

116 hospitals; 540 acupuncture physicians and related staff

were involved.

Four controlling methods were applied in the clinical tri-als, including comparison methods between the acumoxa and

drug therapy in 33 studies; comparison method between dif-

ferent points for exploring the specificity of points in 13 stud-

ies; placebo-controlled trials in 3 studies; normal controlled

trials in 2 studies; and comparison method between acupunc-

ture and transcutaneous electrical stimulation in 1 study.

RESULTS

The results of clinical studies for 33 single acupoints

were:

1. Hegu LI 4

Wang et al1 found that applying electroacupuncture at

LI 4 was effective for toothache. Its analgesic effect was

immediate, but delay analgesic effect was more obvi-

ous. Wang et al2 found that applying electronic

acupuncture at LI 4 could extend the duration of con-

tinuous uterine contractions and shorten the average

time of intermittence, resulting in less usage dosage

of oxytocin.

2. Quchi LI 11

Song et al3 found that applying electroacupuncture at

LI 11 to treat chronic urticaria had better therapeutic ef-

fect than that of control group (using cetirizine) in thenumber and size of skin rashes, edema, itching, fre-

quency, and duration. Yang et al found that applying

electroacupuncture at LI 11 to treat hypertension had

better therapeutic effect than that of control group by

needling Heyang (BL 55).

3. Jianyu LI 15

Fang et al found that applying electroacupuncture at LI

15 was effective for shoulder omarthritis. The effect was

better than that of the control group taking ibuprofen.

4. Qishe ST 11

He et al found that applying acupuncture at ST 11 to

treat goiter had therapeutic effect. There was no signif-

icant difference between the acupuncture treatment

group and control group (using thyroxine tablets) in thy-

roid ultrasonography, sTSH, FT 4, and FT 3. Acupunc-

ture showed better effects in swallowing difficulties,

throat irritation, fullness and distention of chest, and

swelling of the thyroid gland.

5. Tianshu ST 25

Liu et al found that applying electroacupuncture at ST

25 for diarrhea-predominant irritable bowel syndrome

MA ET AL270


3/7

had better effects in the total scores of symptoms, diar-

rhea, and abdominal distention than using SP 15. Zhang

et al found that needling ST 25 to treat constipation had

better effects in improving colonic transit time, reliev-

ing constipation, and better 6-month remote efficacy

than those of the control group by taking lactulose

liquid.

6. Zusanli ST 36Zhang et al found that electroacupuncturing ST 36,

combined with granisetron hydrochloride injection to

relieve the side effects of chemotherapy and radio-

therapy in malignant tumors, had better therapeutic ef-

fect than that of granisetron hydrochloride injection

control group. Acupuncture significantly inhibited

nausea and vomiting caused by chemotherapy. Wu et

al found that electroacupuncturing ST 36 had a defi-

nite clinical effect to prevent adverse reaction in the

stomach and intestine during the process of gastro-

scope examination. Zhao et al found that moxibustion

at ST 36 for the common cold was safe and reliable.

It not only could reduce the incidence of common coldin the elderly, but also reduce the incidences of it and

alleviate the symptoms.

7. Shangjuxu ST 37

Lin found that acupuncturing ST 37 and combined sul-

fasalazine to treat ulcerous colitis had certain effects in

improving ulcerative colitis symptoms, signs and the

points score, the colonic mucosa, and blood integral

state classification. But compared with the effect of tak-

ing sulfasalazine in the control group, the difference was

not significant.

8. Tiaokou ST 38

Guo et al4 found that taking anti-inflammatory anal-

gesics and electroacupuncturing ST 38 to treat peri-arthritis of the shoulder had quick, safe, and stable ef-

fect, and its effect was better than only taking

analgesic drugs. Shao et al found that applying elec-

troacupuncture at ST 38 was effective for periarthri-

tis of the shoulder. The shoulder disorders score stan-

dards (JOA) was used for results evaluation. Results

showed that the effect was better than that of taking

diclofenac sodium sustained-release tablets in the

control group. Xuan et al found that electroacupunc-

turing ST 38 to treat periarthritis of shoulder could re-

markably relieve shoulder pain. The recent, remote ef-

ficacy of sedating pain and improving joint function

were significantly better than those taking nuofuding

tablets in the control group.

9. Fenglong ST 40

Gan et al found that electroacupuncturing ST 40 to treat

hyperlipidemia could improve the overall symptoms

and reduce LDL. Zhang et al5 found that electro-

acupuncturing ST 40 and taking pravastatin both had

the therapeutic effect of reducing blood fat; the differ-

ence between them was not significant.

10. Sanyinjiao SP 6

Gao et al found that electroacupuncturing SP 6 had a

rapid effect in improving signs and symptoms of acute

urinary retention. Cheng et al found that elec-

troacupuncturing SP 6 to treat perimenopausal syn-

drome has obvious therapeutic effects. Compared with

oral drug therapy in the control group, acupuncture had

specific effects on symptoms of flushing, insomnia, ir-ritability, hot feeling in palm and sole, depression, dizzi-

ness, headache, palpitation, and itchy skin. Zhou et al6

found that electroacupuncturing SP 6 to treat peri-

menopausal syndrome was safe and effective. Ma et al

found that electroacupuncturing SP 6 could shorten the

active period of the first stage of labor, ease labor pain,

and reduce bleeding during the birth process and 2 hours

after the labor.

11. Diji SP 8

Wu et al found that electroacupuncturing SP 8 to treat

primary dysmenorrhea and taking ibuprofen both had

good analgesic effect, and there was no significant dif-

ference between them in the clinical symptom score, vi-sual analog score (VAS), and the total effective rate af-

ter 3 months treatment.

12. Shenmen HT 7

Dong et al found that electroacupuncturing HT 7 to treat

insomnia had a therapeutic effect. It prolonged the to-

tal sleep time, shortened the time to fall asleep, reduced

the times of nights awake, improved sleep quality, re-

duced dreams, as well as significantly improving wake-

up.

13. Shaoze SI 1

Wand et al7 found that electroacupuncturing SI 1 to

treat insufficient lactation had better effect than that

of using LI 1 in the control group. Indications werethat SI 1 was a special acupoint for insufficient lac-

tation.

14. Houxi SI 3

Wu et al8 found that electroacupuncturing SI 3 to treat

acute lumbar sprain had better recent and remote ther-

apeutic effect than that of taking MO (MOBIC) tablets

in the control group in sedating lumbar pain and im-

proving lumbar activities.

15. Feishu BL13

Zhao et al found that electroacupuncturing BL13 to treat

bronchial asthma (acute attacking stage) had a thera-

peutic effect. However, compared with the effect of tak-

ing theophylline sustained-release tablets, it showed no

significant difference.

16. Geshu BL17

Lin et al found that electroacupuncturing BL 17 to treat

the side effects of chemotherapy and radiotherapy in

malignant tumors had therapeutic effects. It reduced the

side effects caused by chemotherapy such as poor qual-

ity of life, physical decline, damage to the blood sys-

tem, and gastrointestinal discomfort.

17. Huiyang BL 35

Cen et al9 found that electroacupuncturing BL 35 to treat

female urethral syndrome had better therapeutic effects

than that of Huantiao (GB 30) or Shenshu (BL 23) in

the control group in improving the I-PSS symptom

score, emiction and urodynamic aspects. Better effects

were found after 5 continuous sessions.

18. Zhaohai KI 6Luo et al found that electroacupuncturing KI 6 to treat

chronic pharyngitis was as effective as that of taking

compound caoshanhu buccal tablet. Both improved the

clinical symptoms of chronic pharyngitis.

19. Neiguan PC 6

Wang et al found that applying electroacupuncture at

PC 6 for 10 continuous days may reduce the frequency

of premature heartbeats, and had better therapeutic ef-

fects than that of Xuanzhong(GB 39) in the control

group. Liu et al found that electroacupuncturing PC 6

relieved vomiting, throat discomfort, and other major

reactions caused by gastroscopy. Acupuncture was sim-

ple, well-tolerated in patients, and a safe and effectivenatural therapy. Wang et al found that electroacupunc-

turing PC 6 to treat adverse reactions of the stomach

and intestine was safe and effective.

20. Zhigou SJ 6

Zhang et al found that electroacupuncturing SJ 6 to treat

constipation due to Qi deficiency had significant thera-

peutic effects in improving defecation intervals and

time, degree of bowel and feces traits, and abnormal

colonic transit tests.

21. Fengchi GB 20

Chen et al found that acupuncturing GB 20 had rapid

effects on hypertension (first or second stages). There

was significant differences in the effects of reducingblood pressure between the acupuncture treatment

group and the control group. The control group, in tak-

ing (the Western medicine) metoprolol had better ther-

apeutic effects.

22. Riyue GB 24

Li et al found that acupuncturing GB 24 to treat chronic

cholecystitis had better therapeutic effects than that of

the Kunlun (BL 60) in the control group in relieving

pain and tenderness in the gallbladder.

23. Huantiao GB 30

Wang et al found that electroacupuncturing GB 30 to

treat primary sciatica had a definite clinical efficacy in

easing pain and relieving clinical symptoms.

24. Qiuxu GB 40

Jia et al found that electroacupuncturing GB 40 to treat

migraine had immediate analgesic effects; significantly

better than Tianshu (ST 25) in the control group.

25. Dazhui GV 14

Xiao et al10 found that acupuncturing DU 14 to treat high

fever could lower body temperature; its effect was better

than that of the antipyretic control group.

26. Baihui GV 20

Tang et al found that applying acupuncture at GV 20 by

using a penetrating technique, plus conventional Western

medicine to treat dysfunction of mobility after cerebral

thrombosis, had better therapeutic effects than the con-

ventional Western medicine control group in total effects,

Fugl-Meyer score, neurological impairment score, and

ADL score. Zhang et al found that acupuncturing GV 20,plus conventional treatment to treat depression due to

stroke, had better therapeutic effects than that of the stroke

conventional treatment control group in overall effects and

improving physical and mental anxiety. Zhao et al11 found

that acupuncturing GV 20 to treat depression due to stroke

was as effective as that of taking difenidol.

27. Renzhong GV 26

Fu et al found that electroacupuncturing GV 26, plus

Western medicine to treat mild or moderate shock, had

better therapeutic effects than that of Western medicine.

Zhao et al found that acupuncturing GV 26 to treat acute

lumbar sprain had better therapeutic effects.

28. Zhongji CV 3Liu et al found that electroacupuncturing CV 3 to treat

benign prostatic hyperplasia had significant therapeutic

effects in improving the prostate symptom score, qual-

ity of life index, number of nocturia, urinary line sta-

tus, lower symptoms, biggest urine flow, residual urine

volume, and prostate volume.

29. Zhongwan CV 12

Niu et al12 found that acupuncturing CV 12 had thera-

peutic effects in treating peptic ulcer. Compared with

the comprehensive and gastroscopy efficacy of the

cimetidine control group, results showed no statistical

difference. However, in the initial stage of treatment,

the effect of acupuncturing CV 12 in improving stom-ach pain was superior to that of the cimetidine control

group. The effects of the acupuncture group in improv-

ing chest pains and late GI symptoms was better than

that of the cimetidine control group.

30. Tanzhong CV 17

Chen et al found that electroacupuncturing RN 17 to

treat insufficient lactation had therapeutic effects in im-

proving maternal breast filling, lactation, neonatal

weight, reducing the times of artificial feeding and ca-

pacity, etc. Compared to the effects of the control group

with milk-producing decoction, there was no significant

difference.

31. Sishencong EX-HN 1

Liu et al found that the efficiency of acupuncturing EX-

HN 1 to treat insomnia was 94.2%; PSG monitoring in-

dicators and the SPIEGEL Scale score showed more im-

provement than the Sweet Dream Capsule drug group.

Zhang et al found that acupuncturing EX-HN 1 to treat

insomnia was effective; during treatment, it had signif-

icant effects on relieving insomnia and improving the

quality of sleep.

32. Taiyang EX-HN 5

Zhou et al found that electroacupuncturing EX-HN 5 to

treat migraine of ascendant hyperactivity of Liver Yang

had immediate analgesic effects. Zhao et al13 found that

electroacupuncturing EX-HN 5 could treat central dizzi-

ness caused by vertebrobasilar arterial blood insuffi-

ciency, and improve vertigo symptoms and verte-

brobasilar arterial blood. The effects were better thanthat of electroacupuncturing Ligou (LR 5) in the con-

trol group.

33. Sifeng EX-UE 10

Liang et al14 found that acupuncturing EX-UE 10 of Four

Hands to treat infantile malnutrition had certain effects in

the signs and symptoms of malnutrition, loss of appetite,

subcutaneous fat thickness, weight, and serum albu-

min concentration. Ma et al found that acupuncturing

EX-UE 10 of Four Hands significantly improved the ap-

petite and food intake of children, as well as children with

significantly increased subcutaneous fat, The conditions

of spirit, sleep, abdominal pain, sweat, and hair luster were

also improved in varying degrees.

Summary of the 33 Points

(1) In the 52 studies, results of 40 studies showed the acu-

moxa groups had better therapeutic effects than those in con-

trol groups. Results of 11 studies showed the acumoxa

groups had similar therapeutic effects to those in control

groups. Results of 1 study showed the control group had bet-

ter therapeutic effects than the acumoxa group.

(2) There were 28 acupoints studied in comparison with

the drugs (including ST 38 and GV 20). The results of 12

acupoints studies indicated that the effect of acumoxa groups

was superior to that of drug control groups. Seven acupointsstudies had similar effects in 2 groups. Nine acupoints stud-

ies indicated that acupuncture treatment could strengthen the

role of drug therapy. One acupoint study indicated that the

effect of the drug control group was superior to that of the

acumoxa group. One acupoint study showed that the effect

of acupuncture treatment was not obvious.

There were 13 acupoints studied in comparison with the

other acupoints. Results indicated that 13 acupoints had spe-

cific therapeutic effects on some diseases and symptoms.

There were 3 acupoints studied in comparison with the

placebo control group. Results indicated that the 3 acupoints

had therapeutic effects, except for conciliative effects.

Two acupoints were studied in comparison with blank

control group. Results indicated that the 2 acupoints had

therapeutic effects on the diseases and symptoms.

One acupoint was studied in comparison with transcuta-

neous electrical stimulation. The result indicated that

eletroacupuncture had a better effect.

(3) There were 27 studies with follow-ups, accounting for

51.9%. The remainder of 25 studies were: no follow-ups,

accounting for 48.1%; 13 studies of 27 had good effects

(overall follow-up effects of the treatment groups were sig-

nificantly better than the control groups) in the follow-ups,

accounting for 48.1%; 5 studies showed that the acupoints

had partly better therapeutic effects than other controlled ther-

apies in their follow-ups, accounting for 18.5%; 7 studies in-

dicated that acupoints had similar therapeutic effects to the

controlled therapies in their follow-ups, accounting for 25.9%;

1 study indicated that both groups had therapeutic effectswithout comparison in its follow-up, accounting for 3.7%; and

1 study showed that the treatment group had remote thera-

peutic effects in the follow-up, accounting for 3.7%.

DISCUSSION

In recent years, the studies of acupoints mainly focus on

specificity of acupoints and stimulation techniques of acu-

points, as well as single-acupoint studies. More attention was

given to clinical studies of single acupoints. The clinical

studies of the above-stated 33 Points Indications, which

lasted for 4 years, could be considered as new achievements

in the area of single-acupoint studies.

Points

The single-point clinical studies involved commonly used

33 acupoints, including 30 Meridian acupoints and 3 Extra-

ordinary acupoints, covering 12 Meridians (with the excep-

tion of the Lung Meridian of Hand-Taiyin and the Liver

Meridian of Foot-Jueyin). Among the 33 points, 20 are acu-

points located on the Yang meridians60.7%; 4 are points

located on the Yin meridians12.1%; 6 acupoints are lo-

cated on Conception Vessel and Governor Vessel18.2%;

3 Extraordinary acupoints9.0%. Within the 33 acupoints,

26 of them are specific points (no repeat count), including

6 Five-Shu points, 1 Yuan-Primary point, 2 Luo-Connect-

ing points, 5 Front-Mu points, 1 Back-Shu point, 1 Xi-Cleft

point, 1 Lower He-Sea point, 1 Eight Influential point, 1

Eight Confluence point, 7 Crossing points. The selection of

points in those studies still showed that the main attention

of clinical acupuncture studies was devoted to specific

points, which is similar to the past. Since the clinical study

of the scope of the acupoints remains relatively narrow, the

study on more acupoints needs to be further expanded.

Critiques

The previous clinical studies on indications of single acu-

points used less electroacupuncture stimulation methods, but

more manual acupuncture. They rarely described the rein-

forcing or reducing methods, which made the other studies

hard to follow. Therefore, the experiments could not be ad-

equately repeated.

In the 52 studies, 41 of them were treated with elec-

troacupuncture; 10 of them were treated with manual

acupuncture. One study was treated with moxibustion. The



6/7

same electroacupuncture stimulating parameters were used

in an experiment, so that the results of the study could be

more objective and precise. However, in the above 33 clin-

ical studies, the researchers disregarded the influence of

stimulation volume and method to the clinical effect. It is

expected that more consideration will be given to those fac-

tors to the clinical effect in the future.

Clinical Study Methods on the Indications

of 33 Acupoints

(1) All the clinical studies involved randomized, con-

trolled, clinical trials in multiple centers. Previous studies

on acupoints mostly studied the coordination of several acu-

points, while single-acupoint clinical studies were relatively

fewer, and the related literature was mostly about case stud-

ies. Meanwhile, most single-acupoint clinical studies did not

have control groups and occurred as randomized, controlled

clinical trials in multiple centers; thus, the results couldnot

be proven reliable. The above clinical studies on 33 points

all took randomized, controlled clinical trials in multiplecenters, processed the data scientifically, and attained reli-

able results. However, according to previous clinical study

literature, clinical studies of acupoints need to be system-

atized, such as clinical studies on the expansion of the in-

dications of single acupoints, regularities of the indications,

and mechanisms of the related efficacy.

(2) Most previous clinical studies of acupoints were de-

signed informally and there were no strict diagnostic crite-

ria, participating criteria, exclusion criteria, and standards of

evaluation-which made the studies lacking in scientific

evidence. The above clinical studies on 33 points primarily

used nationally or internationally recognized standards

which enhanced the reliability of the conclusion.

Control Design

Nearly half of the previous studies of acupoints em-

ployed controls, which affects the credibility of the conclu-

sion. In our studies, a total of 52 items adopted parallel

controls and the control designs had 4 categories: blank con-

trol, placebo control, acupoint and drug control, acupoint

and acupoint control.

(1) The trials of blank control were an acupuncture group

and a blank group. There are 2 such studies.

(2) The trials of placebo-control composed of consolation

acupuncture (electroacupuncture group and transcutaneouselectrical stimulation in the control group in 1 study, elec-

troacupuncture group and the consolation electroacupunc-

ture control group in another study), and consolation mox-

ibustion (moxibustion group and sham moxibustion control

group in 1 study), excluding the acupuncture consolation

role to prove the validity of the acupoints.

(3) In acupoint and drug control trials, there were 2 cat-

egories: herbs control and medications control. There were

5 trials of herbs control (including 4 trials of mere acupunc-

ture group with oral herbs group, and 1 of acupuncture plus

oral herbs group with mere oral herbs group), and 27 trials

of medications control (of those, 17 of mere acupuncture

group with oral medications group, 9 of acupuncture plus

oral medications group with mere oral medications group,

1 of acupuncture plus oral medications group with same

medications plus other medications group).(4) The acupoint controlled trials are divided into 4 cate-

gories, A. Acupoint treatment group to correlative acupoint

control group trails; B. Acupoint treatment group to non-cor-

relative acupoint control group trials; C. Acupoint treatment

group to non-points control group trials; and D. Acupoint-

group plus single acupoint treatment group to acupoint-group

control group. Acupoint treatment group to correlative acu-

point control group trials refers to the comparison of effi-

ciency of 2 acupoints which are commonly used in treatment

of the same disease (2 studies used this method). Acupoint

treatment group to acupoint non-correlative control group tri-

als refers to the comparison of efficiency of 2 acupoints; the

acupoint treatment group is commonly used in treatment ofthe disease, while the acupoint in the control group is seldom

used in treatment of the disease (10 studies used this method).

Acupoint treatment group to non-points control group trials

refers to the comparison of efficiency of 2 acupoints; the ori-

entation of the 2 acupoints have different meanings. The non-

acupoints in the control group trial (neither on the meridian,

nor an extraordinary point, nor an Ah Shi point) compares the

real acupoints either located in the meridian or is an extraor-

dinary point. There was 1 study that employed this method.

This kind of trials proves the specificity of acupoint in treat-

ment of the certain disease. Acupoint-group plus single-acu-

point treatment group to acupoint-group control group trial (1

study used this method) suggested that the single point andpoint-group had joint satisfactory effect for a certain disease.

(5) There was 1 study that applied transcutaneous elec-

trical stimulation in the control group.

According to the present clinical study of acupoints, the

process of acupuncture is a visible procedural treatment;

however, to implement a control experiment properly is dif-

ficult, and it is different from placebo control in which pa-

tients could clearly know whether they received acupunc-

ture treatment. Hence, if we want to comply with the

principle of the blind method, we would face many opera-

tional difficulties. It is necessary to continuously develop

the methodology to overcome the difficulties in the future.

Clinical Effects

The clinical studies on 33 points achieved mostly posi-

tive results. Only 1 study showed the effects of acupuncture

to be inferior to the drug control group. One study showed

that acupuncture did not attain the treatment effect. Perhaps

it was due to the acupoints in those studies were usually ef-

fective, verified by the past clinical practice. The results of

MA ET AL274


7/7

those clinical studies proved the effectiveness of the 33 acu-

points on the one hand; conversely, it also proved the su-

periority of acupuncture therapy to certain diseases.

Clinical Follow-up

Follow-up descriptions were fewer than reported in pre-

vious studies; thus, the remote effects of acupuncture were

not clear. The 51.9% of the above clinical studies on the in-dications of 33 acupoints conducted follow-ups with a se-

ries of follow-up data. Hence, the remote effects of acupunc-

ture could be scientifically tested.

Clinical studies on the indications of 33 acupoints demon-

strated that acupuncturing single acupoints to treat diseases

and symptoms had therapeutic effects during a period of ob-

servation. This largest-scale single-acupoints clinical stud-

ies revealed progress in the study of acupoints in accordance

with their multi-center, randomized, and controlled designs.

Compared with the past clinical studies of single acupoints,

these clinical studies were more standardized. At the same

time, prior studies trained a group of acupuncture clinical

study personnel-laying the foundation for the future clin-

ical studies of acupoints. It was expected that it would

strengthen and expand the clinical study of single-acupoints,

and fully integrate with evidence-based medicine and clin-

ical epidemiology methods. Thus, the Chinese acupuncture

studies would be internationally recognized and would pro-

mote the internationalization of Chinese acupuncture and ac-

celerate new progress.
