OBJECTIVETo compare the clinical efficacy on upper limb motor impairment in stroke between the interactive dynamic scalp acupuncture therapy and the traditional scalp acupuncture therapy.

METHODSThe randomized controlled trial and MINIMIZE layering randomization software were adopted. Seventy patients of upper limb with III to V grade in Brunnstrom scale after stroke were randomized into an interactive dynamic scalp acupuncture group and a traditional scalp acupuncture group, 35 cases in each one. In the interactive dynamic scalp acupuncture group, the middle 2/5 of Dingnieqianxiexian (anterior oblique line of vertex-temporal), the middle 2/5 of Dingniehouxiexian (posterior oblique line of vertex-temporal) and Dingpangerxian (lateral line 2 of vertex) on the affected side were selected as the stimulation areas. Additionally, the rehabilitation training was applied during scalp acupuncture treatment. In the traditional scalp acupuncture group, the scalp stimulation areas were same as the interactive dynamic scalp acupuncture group. But the rehabilitation training was applied separately. The rehabilitation training was applied in the morning and the scalp acupuncture was done in the afternoon. The results in Fugl-Meyer for the upper limb motor function (U-FMA), the Wolf motor function measure scale (WM- FT) and the modified Barthel index in the two groups were compared between the two groups before treatment and in 1 and 2 months of treatment, respectively.

RESULTSAfter treatment, the U-FMA score, WMFT score and the score of the modified Barthel index were all apparently improved as compared with those before treatment (all P < 0.01). The improvement in the U-FMA score after treatment in the interactive dynamic scalp acupuncture group was better than that in the traditional scalp acupuncture group (P < 0.05). For the patients of IV to V grade in Brunnstrom scale, WMFT score in 2 months of treatment and the score of Barthel index after treatment in the interactive dynamic scalp acupuncture group were improved apparently as compared with those in the traditional scalp acupuncture group (P < 0.05, P < 0.01). But, for the patients of III grade in Brunnstrom scale, WMFT score and the score of Barthel index after treatment in the interactive dynamic scalp acupuncture group were not different significantly as compared with those in the traditional scalp acupuncture group (both P > 0.05).

CONCLUSIONFor the patients of IV to V grade in Brunnstrom scale in stroke, the interactive dynamic scalp acupuncture therapy achieves the superior improvements of the upper limb motor function and the activity of daily life as compared with the traditional scalp acupuncture therapy, and the longer the treatment lasts, the more apparent the improvements are. For the patients of III grade in Brunnstrom scale, the interactive dynamic scalp acupuncture therapy achieves the similar improvement in the upper limb motor impairment as compared with the traditional scalp acupuncture therapy.

There were 3 000 Zhuangs,1 102 Miaos, and 1 283 Yaos in Baise City of Guangxi,who were enrolled in this population sampling stratfying survey. Height, weight, blood pressure, fasting blood glucose, and lipids were determined, and compared with those of 2 000 Hans of the same town. The prevalence of hypertension and metablic syndrome in Zhuang inhabitants was high, so were the disorders of glycemia and lipidemia, while in Miao and Yao minorities, the prevalences were comparatively lower. The awareness, treatment, and control of hypertension in these minorities were insufficient.

ObjectiveTo realize the relevance between hypertension and serum uric acid (SUA) in residents in Baise City.MethodsTwenty one thousand,five hundred and eighty eight Baise residents were examined.The body weight,height,waist circumference,hip circumference,blood pressure(BP) were recorded and blood lipidlevels,blood glucoseand serum uric acid (SUA) were tested.The relevance between hypertension and hyperuricemia (HUA) was analyzed by multi-factor variance analysis,x2 test,t test,linear regression and Logistic regression analysis.ResultsHypertension prevalence rate was 31.5％,the frequency of HUA was 12.0％,and 5.8％ residents had both.For patients with both hypertension and HUA,when compared to those with normal serum uric level,their mean diastolic blood pressure(DBP) was(84±10),(72±6) mm Hg res-pectively,there mean systolic blood pressure (SBP) was(151±12),(127±6) mm Hg respectively,and pulse pressure (PP) was (50±12),(37±8) mm Hg respectively.The average BMI of those two groups was (23.9±2.6),(21.7±2.4) kg/m2 respectively.The average TC level was (6.0±1.3),(5.2±1.1)mmol/L respectively,the average TG level was(2.3±2.2),(1.5±0.7) mmol/L respectively,and the average LDL-C level was(3.4±1.3),(3.0±1.1) mmol/L respectively.All these parameters were higher than those people without hypertension or HUA(P＜0.01).However,the situation of HDL-C[ (1.2±0.4),(1.5±0.5)mmol/L] was the opposite (P＜0.01).Regression analysis had shown that age,BMI,waist-hip ratio,SUA,blood glucose,TC,TG,HDL-C and LDL-C were independent risk factors for hypertension,while people with HUA was 3.1 times more when compared to those without HUA.The prevalence rate of HUA in people with hypertension was 2.6 times higher than that of the control group.ConclusionHypertension and HUA are two public health problems that prevalent in the residents in Baise City.Obesity,high blood glucose level and hyperlipidemia are thebasis for the development of hypertension and HUA.Hypertension can be the cause of HUA and verse versa.They may have mutual interactions.The adverse effect of HUA on-cardiovascular system should be taken into consideration clinically.

Objective In this study,we attempted to investigate whether Electroacupuncture(EA)could promote the autophagy function in macrophages of inflammatory skin tissues by activating CB2 receptor,thus relieving inflammatory pain induced by CFA in mice,and whether activation of CB2 receptor in NR8383 macrophages cell line can simulate the effect of EA on the autophagy function and mitochondrial damage.Methods Inflammatory pain model was induced by CFA injection into the planta the hind paw of wildtype and CB2 knockout mice.EA or sham EA was applied on the left Huantiao(GB30)and Yanglingquan(GB34)sites.Thermal hyperalgesia was determined with the Hargreaves test.Mechanical sensitivity was assessed with von Frey filaments.NR8383 microphage cell line was used to study the effect of CB2 activation on macrophage function induced by CFA.The expression level of autophagy protein LC3 and p62 in wildtype and CB2 knockout mice skin tissue and NR8383 cell line were determined by Western blot.And flow cytometry analysis was applied to detect damaged mitochondria and mitochondrial superoxide.Results CFA significantly reduced the thermal and mechanical pain threshold in both wildtype and CB2 knockout mice,comparing with the vehicle control groups(P<0.01).EA significantly inhibited thermal and mechanical hyperpathia induced by CFA in wildtype mice(P<0.05),but had no effect on CB2 knockout mice with CFA(P>0.05).CFA significantly increased the expression of p62 protein and decreased LC3-II/I ratio,which was inversed by EA in wildtype mice but wasn't affected by EA in CB2 knockout mice.CFA increased the expression of p62 protein and decreased LC3-II/I ratio in NR8383 cell line,which were inversed by CB2 agonist AM1241.CFA increased mitochondria damage,which were then attenuated by CB2 agonist AM1241.Conclusion The analgesic effect of EA on inflammatory pain induced by CFA was mediated by activation of CB2 receptor,which promoted the autophagy function and the clearance of damaged mitochondria in macrophage.

OBJECTIVETo study the in vitro effect of herb components on scavenging harmful components of cigarette smoke such as radicals, polycyclic aromatic hydrocarbons, nitrosamines in vitro, and its reducing effect on cytotoxicity of cigarette smoke.

METHODspectrophotometry was used to examine the scavenging effect of herb components on DPPH free radicals, superoxide anion radical, and hydroxyl radical, and the results were compared with the anti-oxidation of ascorbic acid. Fluorescence spectroscopy was used to examine the scavenging effect of herb components on polycyclic aromatic hydrocarbons. UV spectrophotometry was used to examine the scavenging effect of herb components on volatile nitrosamines. MTT assay was used to examine cytotoxicity of cigarette smoke.

RESULTAll the herb components showed a certain scavenging effect on DPPH free radicals, superoxide anion radical, hydroxyl radical, polycyclic aromatic hydrocarbons and volatile nitrosamines, espacially the ginkgo biloba extract (GBE), flavonoids of glycyrrhiza, procyanidine, total saponins in ophiopogonin, total saponins of astragalus and epimediun flavonoids. After these six herb components were added to cigarette, the cytotoxicity of cigarette smoke on BEP2D cells was remarkably reduced, by increasing cell survival fraction (SF, %) and mean lethal dose (DML).

CONCLUSIONThe herb components can scavenge harmful components of cigarette smoke such as radicals, polycyclic aromatic hydrocarbons and nitrosamines, which reduce the damage of cigarette smoke on human being.
