Therapeutic effects on spastic cerebral palsy in children Acupuncture and massage at the Shu and He acupoints versus routine acupoints

BACKGROUND： Based on clinical findings and syndromes, it has been previously shown that therapeutic methods for cerebral palsy can be greatly improved by selecting fewer, but more accurate acupoints. Therefore, greater therapeutic efficacy for cerebral palsy could be obtained by selecting the five Shu acupoints, which are located at the qi-intersecting point of the twelve meridians below the elbow and knee. OBJECTIVE： To treat children with spastic cerebral palsy using acupuncture and massage at the Shu and He points through a combination of rehabilitative training, and to compare the effects with routine acupuncture and massage. DESIGN： A randomized controlled clinical trial. SETTING： Rehabilitation Center for Cerebral Palsy, Department of Pediatrics, Affiliated Hospital of Liaoning University of Traditional Chinese Medicine. PARTICIPANTS： Sixty children with spastic cerebral palsy were selected from the Rehabilitation Center for Cerebral Palsy, Department of Pediatrics, Affiliated Hospital of Liaoning University of Traditional Chinese Medicine from May 2003 to February 2006. There were 38 boys and 22 girls, aged 10 months to 4 years old, muscle strength ranging from grade I to grade IV. The children were randomly divided into a treatment group （n =30） and a control group （n =30）. Informed consent for the therapeutic program was obtained from the relatives of all enrolled children. The study was approved by the Hospital＇s Ethical Committee. METHODS： All children were given exercise and occupational therapy based on standard treatments. （1） In the control group, the children were additionally treated with routine acupuncture and massage during the one-month basic rehabilitative training. The acupuncture needles were manipulated alternately at the acupoints of Jianyu, Shousanli, Binao, Hegu, Huantiao, Xuanzhong, and Biguan. They were treated once per day, 6 days a week, followed by one day of rest. The children＇s limbs were first massaged by pressing, stretching, rolling, and kneading. Then, the same acupuncture points were pressed with the thumb for 30 minutes each time, once a day, 6 days a week, followed by one day of rest. The treatment continued for 1 month. （2） In the treatment group, the children were administered acupuncture and massage at the Shu and He points during the one-month basic rehabilitative treatment. For acupuncture of the upper limbs, the following acupoints were used： Sanjian and Quchi of the Large Intestine Meridian of Hand-Yangming, and Houxi and Xiaohai of the Small Intestine Meridian of Hand-Taiyang. The acupoints were acupunctured alternately every other day. For acupuncture of the lower limbs, the following acupoints were used; Zulinqi and Yanglingquan of the Gall bladder Meridian of Foot-Shaoyang, Taibai and Yinlingquan of the Spleen Meridian of Foot-Taiyang, or Xiangu and Zusanli of the Stomach Meridian of Foot-Yangming. The acupoints were acupunctured alternately every other day. Three needles were for the medial malleolus and three needles for the lateral malleolus. They were treated once a day, 6 days a week, followed by one day of rest. The children＇s limbs were first massaged by means of pressing, stretching, rolling, and kneading. The same acupuncture points were then pressed with the thumb for 0.5-1 minute at each point, 30 minutes each time, once a day, 6 days a week, followed by one day of rest. MAIN OUTCOME MEASURES： Therapeutic efficacy was evaluated using gross motor function measurements, as well as activity of daily living scale before and after treatment. RESULTS： All 60 enrolled children with spastic cerebral palsy were included in the final analysis of results. （1） Comparison of gross motor function scores： The gross motor function score after treatment was significantly higher in both the treatment group and control group than before treatment （t = -3.86 and -8.882, respectively, P 〈 0.05）. The scores in the treatment group were significantly higher than the control group scores （t = -7.166, P 〈 0.01）. （2） Changes in activity of daily living scores： The scores for activity of daily living in the treatment group was significantly higher after treatment than before treatment （t = -3.933, P 〈 0.01）, and was also significantly higher than the control group （t = -0.671, P 〈 0.05）. CONCLUSION： Acupuncture and massage at the Shu and He acupoints can significantly ameliorate motor function deficits and movement disabilities in children with spastic cerebral palsy. The therapeutic efficacy at these acupoints is better than routine acupuncture and massage.

Enhanced expression of epidermal growth factor receptor gene in gastric mucosal cells by the serum derived from rats treated with electroacupuncture at stomach meridian acupoints

AIM: To investigate the effect of serum derived from rats treated with electroacupuncture at stomach meridian acupoints on the expression of epidermal growth factor receptor (EGFR) gene in gastric mucosal cells. METHODS: The stress-induced gastric mucosal injury in rat model was established by water-immersion and restrained stress methods. 52 rats were randomly divided into: normal group (n = 8), model group (n = 8), model serum group (n = 12), stomach serum group (n = 12), and gallbladder serum group (n = 12). The gastric mucosal cells were separated by pronase-EDTA digestion method and incubated with serum. The EGFR gene expression in gastric mucosal cells was detected by reverse transcription-polymerase chain reaction (RT-PCR) method. RESULTS: Compared with normal group (0.6860 ± 0.0594), the serum derived from rats of the stomach group (1.2272 ± 0.0813, P = 0.00 < 0.01) and gallbladder group (0.9640 ± 0.0387, P = 0.00 < 0.01) had a tendency to enhance the EGFR gene expression in gastric mucosal cells. Such tendency existed in the model group (0.7104 ± 0.0457) but with no signifi cant difference (P = 0.495 > 0.05) and in model serum group (0.8516 ± 0.0409) with an extremely obvious difference (P = 0.001 < 0.01). Furthermore, the EGFR gene expression in stomach serum group was significantly higher than that in gallbladder serum group (P = 0.00 < 0.01). CONCLUSION: The present study shows that serumderived from rats treated with electroacupuncture at stomach meridian acupoints can distinctly increase the EGFR gene expression of gastric mucosal cells. Therefore, there is certain meridian specificity in the serum, which could provide a proof for the TCM theory “particular relation between meridian and internal organ”.

EXPERIMENTAL STUDY OF THE ACUPUNCTURE EFFECTS ON CALCIUM ION CONCENTRATION IN RABBITS' ACUPOINTS

In this article, the concentration of calcium ion(Ca21 ) in rabbits’ acupoints hasbeen observed in vivo by means of the Ca21 selective acupuncture electrode (Ca21 SAE). We discov-ered that stimulating the acupoints in the meridian could cause the Ca21 concentration increasing inother points of the same meridian but reducing in the control points （lateral to the meridian points）.The results indicate that Ca21 may involve in the activities of the meridians.

CLINICAL OBSERVATION ON 50 CASES OF WIND STROKE TREATED MAINLY BY ACUPUNCTURE AT 13 POINTS ALONG THE DU MERIDIAN

The acupuncture at 13 points along the Du meridian - Baihui, Fengfu, Dazhui, Taodao, Shenzhu, Shendao, Zhiyang, Jinsuo, Jizhong, Xuanshu, Mingmen, Yaoyangguan and Changqiang is an empirical recipe originated by Wang Leting, a senior in the acupuncture circles. I used this set of acupoints in the treatment of 98 cases of wind stroke, and its therapeutic result (50cases) was compared with control (48 cases). It is indicated that this therapy is more effective (P< 0.05) than the control.As one of the eight extra-meridians, Du meridian is the governor of all the Yang meridians and connected with the brain and spinal cord. Acupuncture at the points along the Du meridian may regulate flow of many other meridians and effectively treat wind stroke.

SEGMENTAL DISTRIBUTION OF AFFERENT ELECTRO-ACUPUNCTURE SIGNALS FROM ACUPOINTS OF THE PERICARDIUM MERIDIAN IN THE RAT

Objective: To observe the segmental distribution of afferent Electroacupuncture (EA) signals from acupoints of the Pericardium (PC) Meridian and try to analyze the relative specificity of running route of PC Meridian.Methods: A total of 85 Wistar rats anesthetized with mixed solution of Chloralose (5 mg/100 g) and Urethane (42 mg/100g) were used in this study. Under microscopic observation, the micro-filaments of the distal end of the dorsal root were carefully separated after tearing the spinal pia mater to attach to a recording electrode. The reference electrode was placed beneath the skin of the incision. Two caudal and two rostral dorsal roots near the recorded one were cut off separately. Electrical activity of the isolated micro-filaments was observed before and after EA of "Daling" (PC 7) -"Jianshi" (PC 5), "Quze" (PC 3) of PC Meridian, "Yangchi"(TE 4)- "Zhigou" (TE 6), "Tianjing" (TE 10)-" Qin-glengyuan" (TE 11) of the Triple Energizer (TE) Meridian with electric current 1 mA and 2 mA and double pulses. Results: ① After EA (1 mA) of "Daling"(PC 7)-"Jianshi"(PC 5), the firing rates of 3 out of 10 (33.3%) micro-filaments in C5 segment, 5 out of 10 (50.0%) in C6, 7 out of 10 (70.0%) in 07, 3 out of 10 (30.0%) in C8 and 3 out of 13 (23. 1%) in T1 increased considerably；and after EA of "Quze" (PC 3), those of 3/10 of C5, 4/10 of C6, 6/10 of C7, 3/10 of C8, and 3/10 of T1 increased significantly. ② After EA (1 mA) of "Yangchi"(TE 4)- "Zhigou" (TE 6) and "Tianjing" (TE 10)- "Qinglengyuan" (TE 11). the firing rates of 2/10, 2/10 of micro-filaments In C5, 7/10, 3/10 of C6, 5/10 and 4/10 of C7, 1/10 and 1/10 of C8, and 2/13 and 1/10 of T1 increased significantly. It indicates that C7 dorsal root may play the first important role in conveying EA signals from PC Meridian acupoints to the spinal cord, while C6 and C7 may be mainly responsible for conveying EA signals from TE Meridian acupoints to the spinal cord. Conclusion: The peripheral afferent pathway for transmitting EA signals from PC Meridian acupoints probably has a relative specificity.

Clinical Study on the Effect of Acupuncture and Moxibustion with the Method of Acupoints on the Treatment of Chronic Gastritis with Sleep Disorder

Objective:To explore the clinical effect of acupuncture and moxibustion with acupoints on the treatment of chronic gastritis with sleep disorders.Methods:Sixty patients with chronic gastritis and sleep disorders in our hospital from January 2018 to January 2019 were selected and recruited.These patients were divided into two groups,namely the control group and experimental group by using random number table method.Each group consisted of 30 cases.The control group was treated with conventional drugs,whereas the observation group was treated with acupuncture and moxibustion with acupoints on top of the treatment prescribed for the patients in control group.The TCM syndrome score,gastrin level,and sleep quality level were compared between the two groups.Results:After four weeks of treatment,the Traditional Chinese Medicine(TCM)symptom score,gastrin level,and Pittsburgh Sleep Quality Index(PSQI)score in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).Conclusion:Acupuncture and moxibustion with acupoints can improve TCM symptom scores,reduce gastrin levels,and improve sleep quality in patients with chronic gastritis and sleep disorders.

RELATIONSHIP OF ACUPOINTS AND MERIDIANS TO CONNEXIN 43

Objective To explore the relationship between connexin 43 and acupoints and meridians. Methods we detected one major skin gap junction connexin （connexin43, Cx43） in meridians and acupoints, and studied the expression of Cx43 in Zusanli （足三里 ST 36） acupoints compared with control non-acupoint regions in rats after acupuncture treatments. The expression of Cx43 was detected by using immunohisto- chemistry, immunoblotting, and RT-PCR for Cx43 protein and mRNA level. Results The results showed much more abundant Cx43 expression in some cells in the skin and subcutaneous tissue of rat at ST 36 acupoints and bladder and kidney meridians than that of in the controls. The mRNA and protein levels of Cx43 in acupoints were significantly higher than those of in the control points in non-acupuncture groups and even more so after acupuncture treatments. Conclusion Our research implied that connexins and gap junctions could have a close relationship to acupoints and meridians, and gap junctional intercellular communication might play an important role in the effect of acupuncture.

Acupuncture at the Taixi(KI3) acupoint activates cerebral neurons in elderly patients with mild cognitive impairment

Our previous ifndings have demonstrated that acupuncture at the Taixi （KI3） acupoint in healthy youths can activate neurons in cognitive-related cerebral cortex. Here, we investigated whether acupuncture at this acupoint in elderly patients with mild cognitive impairment can also activate neurons in these regions. Resting state and task-related functional magnetic resonance imaging showed that the pinprick senstation of acupuncture at the Taixi acupoint differed signiifcantly between elderly patients with mild cognitive impairment and healthy elderly controls. Results showed that 20 brain regions were activated in both groups of participants, including the bi-lateral anterior cingulate gyrus （Brodmann areas [BA] 32, 24）, left medial frontal cortex （BA 9, 10, 11）, left cuneus （BA 19）, left middle frontal gyrus （BA 11）, left lingual gyrus （BA 18）, right medial frontal gyrus （BA 11）, bilateral inferior frontal gyrus （BA 47）, left superior frontal gyrus （BA11）, right cuneus （BA 19, 18）, right superior temporal gyrus （BA 38）, left subcallosal gyrus （BA 47）, bilateral precuneus （BA 19）, right medial frontal gyrus （BA 10）, right superior frontal （BA 11）, left cingulate gyrus （BA 32）, left precentral gyrus （BA 6）, and right fusiform gyrus （BA 19）. These results suggest that acupuncture at the Taixi acupoint in elderly patients with mild cogni-tive impairment can also activate some brain regions.

Improvement in acupoint selection for acupuncture of nerves surrounding the injury site: electro-acupuncture with Governor vessel with local meridian acupoints

Peripheral nerve injury not only affects the site of the injury, but can also induce neuronal apop- tosis at the spinal cord. However, many acupuncture clinicians still focus only on the injury site, selecting acupoints entirely along the injured nerve trunk and neglecting other regions; this may delay onset of treatment efficacy and rehabilitation. Therefore, in the present study, we compared the clinical efficacy of acupuncture at Governor vessel and local meridian acupoints combined （GV/LM group） with acupuncture at local meridian acupoints alone （LM group） in the treatment of patients with peripheral nerve injury. In the GV/LM group （n = 15）, in addition to meridian acupoints at the injury site, the following acupoints on the Governor vessel were stimulated： Baihui （GV20）, Fengfu （GV16）, Dazhui （GV14）, and Shenzhu （GV12）, selected to treat nerve injury of the upper limb, and Jizhong （GV6）, Mingmen （GV4）, Yaoyangguan （GV3）, and Yaoshu （GV2） to treat nerve injury of the lower limb. In the LM group （n = 15）, only me- ridian acupoints along the injured nerve were selected. Both groups had electroacupuncture treatment for 30 minutes, once a day, 5 times per week, for 6 weeks. Two cases dropped out of the LM group. A good or excellent clinical response was obtained in 80% of the patients in the GV/ LM group and 38.5% of the LM group. In a second study, an additional 20 patients underwent acupuncture with the same prescription as the GV/LM group. Electomyographic nerve conduc- tion tests were performed before and after acupuncture to explore the mechanism of action of the treatment. An effective response was observed in 80.0% of the patients, with greater motor nerve conduction velocity and amplitude after treatment, indicating that electroacupuncture on specific Governor vessel acupoints promotes functional motor nerve repair after peripheral nerve injury. In addition, electromyography was performed before, during and after electroacu- puncture in one patient with radial nerve injury. After a single session, the patient＇s motor nerve conduction velocity increased by 23.2%, indicating that electroacupuncture at Governor vessel acupoints has an immediate therapeutic effect on peripheral nerve injury. Our results indicate that Governor vessel and local meridian acupoints used simultaneously promote functional repair after peripheral nerve injury. The mechanism of action may arise from an improvement of the local microenvironment in injured nervous tissue, as well as immediate effects of Governor vessel and local meridian acupoint stimulation to ensure the continuity between the peripheral and central nervous systems.

Acupuncture at heterotopic acupoints enhances jejunal motility in constipated and diarrheic rats

AIM: To investigate the effect and mechanism of acupuncture at heterotopic acupoints on jejunal motility, particularly in pathological conditions.

Activation of various brain areas during acupuncture at Taixi (KI 3) and Qiuxu (GB 40) acupoints

A number of previous studies of acupuncture acupoint specificity have used sham acupoints, sham acupuncture or meridian acupoints at a great distance from each other as controls in functional MRI （fMRI） experiments. However, few studies have compared different meridian acupoints within the same segment, which are associated with similarly intense needle sensations. We performed fMRI on 12 healthy young volunteers and observed differences in brain activation elicited by acupuncture of the Taixi （KI 3） and Qiuxu （GB 40） acupoints. Acupuncture was applied at the Taixi and Qiuxu acupoints, using a multiple-block fMRI design with three blocks, involving three altemations of resting and task phases. After scanning, needle sensation was assessed. The behavioral results revealed that the subjective needle sensation was similar between the Taixiand Qiuxu acupoints. The fMRI results revealed that acupuncture at the right Taixi acupoint activated the right superior temporal gyrus （BA 22）, left middle frontal gyrus （BA 46） and inferior frontal gyrus （BA 45）, bilateral parietal lobe postcentral gyrus （BA 2）, right parietal lobe （BA 3）, and left parietal lobe （BA 40）. Acupuncture at the right Qiuxu acupoint activated the left superior temporal gyrus （BA 42）, right parietal lobe postcentral gyrus （BA 40, BA 43）, right inferior frontal gyrus （BA 47）, bilateral superior temporal gyrus （BA 22）, and right insula BA13. These results suggest that the right Taixiand Qiuxu acupoints activated different brain areas.

Modulatory effect of International standard Scalp Acupuncture on brain activation in the elderly as revealed by resting-state fMRI

The specific mechanisms by which acupuncture affects the central nervous system are unclear. In the International Standard Scalp Acupuncture system, acupuncture needles are applied at the middle line of the vertex, anterior parietal-temporal oblique line, and the posterior parietal-temporal oblique line. We conducted a single-arm prospective clinical trial in which seven healthy elderly volunteers (three men and four women;50–70 years old) received International Standard Scalp Acupuncture at MS5 (the mid-sagittal line between Baihui (DU20) and Qianding (DU21)), the left MS6 (line joining Sishencong (EX-HN1) and Xuanli (GB6)), and the left MS7 (line joining DU20 and Qubin (GB7)). After acupuncture, resting-state functional magnetic resonance imaging demonstrated changes in the fractional amplitude of low frequency fluctuations and regional homogeneity in various areas, showing remarkable enhancement of regional homogeneity in the bilateral anterior cingulate, left medial frontal gyrus, supramarginal gyrus, right middle frontal gyrus, and inferior frontal gyrus. Functional connectivity based on a seed region at the right middle frontal gyrus (42, 51, 9) decreased at the bilateral medial superior frontal gyrus. Our data preliminarily indicates that the international standard scalp acupuncture in healthy elderly participants specifcally enhances the correlation between the brain regions involved in cognition and implementation of the brain network regulation system and the surrounding adjacent brain regions. The study was approved by the Ethics Committee of the China-Japan Union Hospital at Jilin University, China, on July 18, 2016 (approval No. 2016ks043).
