OBJECTIVETo compare the efficacy difference between triple acupuncture method at cervical Jiaji (EX-B 2) and conventional acupuncture for cervicogenic headache.

METHODSA total of 66 patients were randomly divided into a triple acupuncture group and a conventional acupuncture group, 33 cases in each one. The acupoints selected in the two groups were identical, including C1 to C7 of cervical Jiaji (EX-B 2) as well as Baihui (GV 20), Qiangjian (GV 18), Naokong (GB 19), Fengchi (GB 20), Fengfu (GV 16), Tianzhu (BL 10), etc. The conven- tional acupuncture was performed at acupoints on the head in the two groups; triple acupuncture was performed at cervical Jiaji (EX-B 2) in the triple acupuncture group while perpendicular acupuncture was performed with a depth of 25 to 40 mm in the conventional acupuncture group. The treatment was given once a day. Five treatments were considered as one session and totally two sessions were required. The changes of simplified McGill scale before and after acupuncture were observed in the two groups, and the efficacy of the two groups was compared.

RESULTSAfter acupuncture, the simplified McGill scale was both reduced in the two groups (both P < 0.01), and there was no significant difference between the two groups after treatment (all P > 0.05). The cured and markedly effective rate was 75.8% (25/33) and the total effective rate was 93.9% (31/33) in the triple acupuncture group, which were superior to 57.6% (19/33, P < 0.01) and 84.8% (28/33, P < 0.05) in the conventional acupuncture group respectively.

CONCLUSIONThe efficacy of triple acupuncture method at cervical Jiaji (EX-B 2) is superior to that of conventional acupuncture for cervicogenic headache.

BACKGROUND:Magnesium alloy is a material that is easily degradable and has good mechanical properties.OBJECTIVE:To study the effects of the two kinds of magnesium aloy materials (AM50 and WE43) on proliferation and morphology of human umbilical vein endothelial cells.METHODS: Human umbilical vein endothelial cells at logarithmic phase were cultured in 100%, 50%, 10% extracts of AM50 and WE43 or directly seeded on the surface of AM50 and WE43 for 24 hours to study the morphological effect of magnesium alloys on the cells. Human umbilical vein endothelial cells cultured routinely served as negative controls. Relative growth rate of the cells was detected at 12, 24, 48 hours after culture. Cell morphology was observed using immunofluorescence staining at 24 hours after culture, and pH and element levels in the cell supernatant were measured.RESULTS AND CONCLUSION: (1) AM50 and WE43 extracts showed no effects on the proliferation of human umbilical vein endothelial cells in comparison with the negative control group. (2) Compared with the negative control group, reduced area of human umbilical vein endothelial cells was found on the surface of AM50 or WE43 alloy by the immunofluorescent staining, and the cytoskeleton of the cytoplasm was blurred. However, after 24 hours of culture, morphological changes of the cells cultured in 10%, 50% and 100% AM50 or WE43 extracts were consistent with those cultured routinely. The cytoskeleton of the cytoplasm was clearly visible. (3) Compared with the negative control group, the pH values of 100% AM50 and WE43 extract groups were significantly upregulated, and the level of magnesium element was also increased remarkably. In summary, AM50 and WE43 alloys possess good cytocompatibility with human umbilical vein endothelial cells, and have no influence on the cell proliferation and growth.

Objective:To establish a volt-ampere polarography method for the determination of thimerosal in chondroitin sulfate eye drops, and study the adsorption of thimerosal in different packing materials. Methods:The hanging mercury drop electrode ( HM-DE) in multi-functional electrode was used and the sample solution was added to potassium chloride-hydrochloric acid buffer solution. Nitrogen deoxygenation time was 200 s, the enrichment time was 60 s, and the equilibrium time was 5 s. The potentiometric scan was performed using a two standard addition method. Results:Thimerosal had a good linear relationship within the range of 0. 01-1. 0 mg· ml-1(r=0. 9990). The detection limit was 1. 78 μg·ml-1 and the average recovery was 99. 1% (RSD=2. 7%, n=9). Conclu-sion:The method is simple and accurate, and suitable for the determination of thimerosal in chondroitin sulfate eye drops. Low-density polyethylene and polypropylene both show obvious adsorption of thimerosal,so chondroitin sulfate eye drops should not be packed in the above packing materials.

The human tissue kallikrein(KLK)gene family consists of 15 highly conservative serine pro-teases,which is the largest uninterrupted cluster of protease genes in the human genome. Several members of the family are expected to be markers for tumor diagnosis and prognosis. Studies find that the expressions of KLK2-11 and KLK13-15 are abnormal,and the majority of KLKs have potential diagnostic and prognostic values.

Objective To develop a questionnaire which measures leisure satisfaction for university students. Methods Initial items of the questionnaire were compiled according to theoretical analysis and interviews. 400 college students were recruited to respond to the items. The explorative factor analysis was used to decide the final items and dimensions. Another 350 college students were recruited to respond to the decided questionnaire and a criterion questionnaire. Results The leisure satisfaction questionnaire consisted of three dimensions : Relaxing Satisfaction (RS) , Contacting Satisfaction (CS), and Transcend Satisfaction (TS). Internal consistency (Cronbach' sα) of the three dimensions were 0.86,085 and 0. 84 and the Cuttmann Split-half Coefficient were 0.76,0.83 and 0.86. The cumulative explanation of the variance was 58.956%. A confirmative factor analysis revealed that the three-dimension model was proper(x2/df = 1. 74, NFI = 0.88, NNFI = 0.93, CFI = 0.94, GFI =0.93,AGFI=0.91,IFI=0.94,RMSEA =0.048). The leisure satisfaction Questionnaire was positively related to freedom satisfaction( r = 0.20 ～ 0. 30, P < 0.01). Conclusion The leisure satisfaction questionnaire for university students has satisfactory psychometric characteristics.

Objective To test the hypothesis that IL-10 may promoting left ventricular remodeling and cardiac function by modulating extracellular matrix after acute myocardial infarction. Methods Male adult rats were randomly divided into three groups:control group (n=6),MI/AAV2 group (n=16) and MI/AAV2-IL-10 group (n=16). Establishing animal modol of experimental myocardial infarction and recombinant adeno-associated virus type 2 (AAV)/IL-10 (AAV2-rhIL-10) and AAV2 were injected around the ischemic zone. Echocardiography parameters,hemodynamic parameters,left ventricular mass index (LVMI),collagen volume fraction (CVF),perivascular circumferential area (PVCA),collagen type Ⅰ&Ⅲ volume fraction and mRNA levels of collagen type Ⅰ&Ⅲ,matrix metalloproteinases-2 (MMP-2) and tissue inhibitor of metalloproteinase-1 (TIMP-1) were compared among the three groups. Results Improved cardiac function was observed in MI/AAV2-IL-10 group shown by echocardiography and hemodynamic examination. Four weeks after myocardial infarction,thickness of different parts of LV was not different in MI/AAV2-IL-10 group and MI/AAV2 group. Nevertheless CVF,PVCA and collagen type Ⅰ volume fraction was significantly descending in remote zone of MI/AAV2-IL-10 group compared with that of MI/AAV2 group. The mRNA expression of collagen type I and MMP-2 was lower in MI/AAV2-IL-10 group than that in MI/AAV2 group. Conclusion Recombinant IL-10 expression mediated by AAV2-rhIL-10 transfection of rats' myocardium promotes LV remodeling and cardiac function after acute myocardial infarction. The promotion was partially achieved by inhibition myocardium collagen deposition.
