[Clinical effect on infantile food accumulation treated with centripetal tuina therapy at spleen meridian site of different location].

OBJECTIVE: To compare the difference in the clinical efficacy on infantile food accumulation treated with centripetal tuina therapy at spleen meridian site of different location. METHODS: Sixty cases of infantile food accumulation were randomized into a palmar thumb surface group and a radial margin group, 30 cases in each one. In the palmar thumb surface group, the spleen meridian was stimulated with the pushing technique centripetally on the palmar side of the thumb. In the radial margin group, the spleen meridian was stimulated with the pushing, technique centripetally along the radial margin of the thumb. The traditional tuina techniques, such as tuisanguan, yun neibagua were combined in the two groups. The treatment was given once a day, 6 times a week, 12 treatments as one session. After the 1 session of treatment, the main symptom scores before and after treatment were compared in the patients of the two groups, the improvements in the accompanied symptoms were observed, such as appetite, defecation and tongue coating; and the efficacy was evaluated in the two groups. RESULTS: The total effective rates were 93.3% (28/30) and 90.0% (27/30) in the palmar thumb surface group and the radial margin group respectively and the difference was not significant statistically in comparison of the two groups (P > 0.05). After treatment, the main symptom score was improved significantly in the two groups, indicating the significant difference as compared with that before treatment (both P < 0.05). The improvement in foul breathing in the palmar thumb surface group was better than that in the radial margin group (P < 0.05). CONCLUSION: Between the two kinds of pushing techniques at spleen meridian site, pushing on the palmar surface of the thumb and pushing along the radial margin, there is no difference in the total efficacy on infantile food accumulation. Regarding the improvement in foul breathing, the effect in the palmar thumb surface group is better than that in the radial margin group.

[Acupuncture combined with western medicine for CP/CPPS:a randomized controlled trial].

OBJECTIVE: To compare the clinical efficacy differences among acupuncture combined with western medicine, acupuncture alone and western medicine alone for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). METHODS: Ninety patients were randomly assigned into a needle-medicine group, an acupuncture group and a western medicine group, 30 patients in each group. The patients in the needle-medicine group were treated with acupuncture combined with western medicine; the scalp points included Shenting (GV 24), Xinhui (GV 22), Qianding (GV 21), Baihui (GV 20), Chengguang (BL 6), Tongtian (BL 7), etc. The body points were Zhongji (CV 3), Guanyuan (CV 4), Pangguangshu (BL 28), Ciliao (BL 32), etc. The acupuncture was given 30 min per treatment, once a day. Besides, oral administration of 0.2g levofloxacin (twice per day) and 0.2 mg tamsulosin (once a day) was applied. The patients in the acupuncture group and western medicine group were treated by acupuncture and western medicine respectively. 12-d treatment was taken as one session, and totally 2 sessions were given. The clinical efficacy of the three groups after treatment was compared as well as the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) total score and pain score, self-rating anxiety scale (SAS) and self-rating depression scale (SDS) before and after treatment. RESULTS: During the trial two patients dropped out, as a result, 30 patients in the needle-medicine group, 29 patients in the acupuncture group and 29 patients in the western medicine group were included in the analysis. After treatment, 21 patients were cured, 6 patients were markedly effective, 2 patients were effective and 1 patient failed in the needle-medicine group;12 patients were cured, 10 patients were markedly effective, 5 patients were effective and 2 patients failed in the acupuncture group; 11 patients were cured, 12 patients were markedly effective, 4 patients were effective and 2 patients failed in the medicine group; the efficacy in the needle-medicine group was superior to those in the acupuncture group and medicine group (both P<0.05). Each score was improved after treatment in each group (all P<0.01); the total score of NIH-CPSI as well as SAS and SDS scores in the needle-medicine group were superior to those in the acupuncture group and medicine group (P<0.05, P<0.01); the pain scores of NIH-CPSI in needle-medicine group and acupuncture group were superior to that in the medicine group (P<0.05, P<0.01), but the difference between the needle-medicine group and acupuncture group was not significant (P>0.05). CONCLUSIONS: The efficacy of acupuncture combined with western medicine for CP/CPPS is superior to that of acupuncture alone and western medicine alone, which could improve the symptom of prostatitis as well as status of anxiety and depression.

[Effect of moxibustion intervention on expression of gastric epidermal growth factor receptor and extracellular signal regulated kinase 1/2 expression in rats with gastric ulcer].

OBJECTIVE: To observe the effect of moxibustion on epidermal growth factor receptor (EGFR) and phosphorylated extracellular signal regulated kinase 1/2(p-ERK1/2) protein expression in gastric ulcer (GU) rats so as to reveal its mechanisms underlying improving GU. METHODS: Fifty SD rats were randomly allocated to control,model, medication ("Sijunzi" Decoction), non-acupoint moxibustion (non-acup-moxi), and acup-moxi groups (n=10 in each group). The GU model was established by intragastric perfusion of absolute alcohol. Rats of the control group were treated by gavage of distilled water. Rats of the medication group were treated by administration of "Sijunzi" Decoction (8 mL x kg(-1) d(-1)),twice a day for 8 days. Moxibustion intervention was applied to bilateral "Zusanli" (ST 36),"Zhongwan" (CV 12),and "Pishu" (BL 20), "Weishu" (BL 21) alternatively for 30 min, once daily for 8 days. The animals' ulcer index (UI) was assessed by Guth's method, and gastric mucosal pathological changes were observed under light microscope following H. E. staining. The expression of gastric EGFR was detected by immunohistochemistry and that of phosphorylated ERK1/2 (p-ERK1/2) protein determined by Western blot. RESULTS: Compared with the control group, the UI, gastric EGFR and p-ERK1/2 protein expression levels were significantly increased in the model group(P<0.01, P<0.05); whereas in comparison with the model group, the UI was notably decreased in the medication, non-acup-moxi and acup-moxi groups (P<0.05, P<0.01), and EGFR and p-ERK1/2 protein expression levels were further up-regulated in the three treatment groups (P<0.01). The effects of both medication and acup-moxi groups were obviously superior to those of the non-acup-moxi group (P<0.01, P<0.05). No significant differences were found between the medication and acup-moxi groups in the expression levels of EGFR and p-ERK1/2 proteins (P>0.05). Results of H.E. staining showed that alcohol-induced gastric mucosal injury as breakage, exfoliation, inflammatory cell infiltration, etc. was milder in both medication and acup-moxi groups following the treatment. CONCLUSION: Acupoint-moxibustion has a role in relieving alcohol induced gastric mucosal injury in the rat, which may be closely associated with its effects in up-regulating activities of the EGFR/ERK signal transduction pathway.

[Effect of acupoint-catgut-embedding intervention on type II diabetic rats].

OBJECTIVE: To observe the effect of acupoint-catgut-embedding therapy on blood lipid and insulin levels in type I diabetes mellitus rats;s as to reveal its mechanism underlying improvement of pancreatic functions. METHODS: Thirty SD rats were divided into normal, model and treatment group. The type I diabetes model was established by feeding the rats with high-fat diet and intraperitodneal injection of streptozotocin (STZ). Catgut-embedment was performed in acupoint "Zhongwan" (CV 12)-"Xiawan" (CV 10), "Yishu"-"Ganshu" (BL 18), etc., once every 20 days, twice altogether. Fasting blood glucose (FBG) content was assayed by glucose oxidase method; glycosylated hemoglobin A 1 c (HbA 1 c) assayed by ELISA, and serum fasting C-peptide(FC-p) deterriined by chemiluminescence method; and the triglyceride (TG), total cholesterol (TC), and serum insulin (INS) levels were detected by enzymatic method, separately. The rat's pancreas tissues were fixed with 4% paraformaldehyde and cut into sections (4 Im in thickness) and stained with H. E. method. RESULTS: After modeling, the levels of FBG, HbA 1 c, INS and FC-p, TG, TC were significantly increased in the model group in comparison with those of the normal group (P<0.05), while INS sensitive. index was apparently decreased in the model group (P<0.05). Following catgut-embedding treatment, changes of the above-mentioned indexes were all remarkably reversed (P<0.05), and H.E. staining showed an improvement of the injured pancreatic tissue and islet cells. CONCLUSION: Catgut-embedding therapy can reduce fasting blood glucose and insulin resistance, and improve lipid metabolism in type I diabetic rats, which may contribute to its effect in protecting pancreatic islet cells.

[Effects of electroacupuncture intervention on expression of pulmonary metalloproteinase-9 and tissue inhibitor-1 proteins in rats with chronic obstructive pulmonary disease].

OBJECTIVE: To observe the effect of electroacupuncture (EA) stimulation on the expression of metalloprotei- nase-9 (MMP-9) and tissue inhibitor-1 (TIMP-1) in the lung tissue in rats with chronic obstructive pulmonary disease (COPD), so as to reveal its mechanisms in protecting the lung tissue. METHODS: Forty male SD rats were equally randomized into control, model, medication and EA groups. The COPD model was established by smoke-fumigation method (passive smoking in a closed box) and endotracheal injection of lipopolysaccharide (200 microg/100 microL) for 30 days. Rats of the medication group were treated by i.p. of dexamethasone acetate injection (2.0 mg/kg), once daily for 22 days. EA was applied to LU 9, ST 36, ST 40 and KI 3 for 20 min, once daily for 22 days. Pathological changes of the pulmonary tissue were observed under optical microscope after hematoxylin and eosin (H.E.) staining. The expression of pulmonary MMP-9 and TIMP-1 was assayed by immunohistochemistry. RESULTS: H.E. staining showed pulmonary diffuse edema, severe inflammatory cell infiltration, and increase of the numbers of goblet cells, proliferation of fibroblasts, etc. in the model group which were relatively milder in the medication and EA groups. The expression levels of pulmonary MMP-9 and TIMP-1 proteins were significantly higher in the model group than in the control group (P<0.05), and were considerably down-regulated in both EA and medication groups in comparison with the model group (P<0.05). There were no significant differences between the EA and medication groups in MMP-9 and TIMP-1 expression levels (P>0.05). CONCLUSION: EA can effectively suppress the increased expression of pulmonary MMP-9 and TIMP-1 in COPD rats, which may contribute to its effect in improving COPD-induced pathological changes.

[Effect of electroacupuncture of different acupoints on plasma and cerebral endothelin and CGRP contents in acute cerebral ischemia rats].

OBJECTIVE: To investigate the underlying mechanism of electroacupuncture (EA) of "Shuigou" (GV 26) and "Baihui" (GV 20), "Ganshu" (BL 18) and "Shenshu" (BL 23) in resisting cerebral ischemia (CI). METHODS: Sixty male SD rats were randomly divided into pseudo-operation group, model group, GV26-GV20 group, and BL18-BL23 group, with 15 cases in each. CI model was established by middle cerebral artery occlusion (MCAO). EA (2/30 Hz,2 mA) was applied to GV26, GV20, BL18 and BL23 for 30 min every time and for 6 times. Neuroethologic scores of the rats were evaluated, plasma and cerebral endothelin (ET) and calcitonin gene-related peptide (CGRP) contents were determined by radioimmunorassay. RESULTS: 1) After MCAO for 72 hours, the rats' neuroethologic score, plasma and cerebral ET contents in model group increased significantly in comparison with those of pseudo-operation group (P<0.05, 0.01), and plasma and cerebral CGRP levels decreased considerably (P<0.01). Compared with model group, the neuroethologic scores, cerebral ET contents of GV26-GV20 and BL18-BL23 groups decreased significantly after CI (P<0.01); and plasma and cerebral CGRP levels in two EA groups increased significantly (P<0.05, 0.01). No significant differences were found between two EA groups in these 3 indexes (P>0.05). CONCLUSION: EA of GV26-GV20 and BL18-BL23 can improve CI rats' behavior activity, which may be related to its effects in lowering cerebral ET and raising blood and cerebral CGRP levels.
