Methods A total of 1230 community residents were randomly enrolled from 8 of 16 communities in Yantian District of Shenzhen City. The behavior information of the participants was collected through face-to-face interviews. A systematic intervention was carried out to the target residents, and the outcomes were evaluated. Results The awareness of healthy behaviors was improved and unhealthy behaviors (i. e. lack of physical activity,over-intake of salt, cigarette smoking,alcohol consumption,irregular health check-up, long-time watching TV) were significantly reduced ( P < 0. 05 ). Conclusions Systematic intervention could be an effective way to reduce unhealthy behaviors of community residents.

OBJECTIVE:To analyze the constituents of volatile oil in Artemisia indica from different area of Guangxi, and to compared which with those in Artemisia argyi. METHODS: The volatile oil was extracted from Artemisia indica and Artemisia argyi respectively by steam distillation. The constituents of the volatile oil were identified by GC-MS technology. RESULTS: The yield of the collected volatile oil of Artemisia indica from different area of Guangxi was 0.32%～0.67%, and compared with Artemisia argyi, both were found to contain the following main constituents: eucalyptol, camphor, borneol, germacrene D, caryophyllene, caryophyllene oxide, terpineol, azulene etc. But the content of the same constituents in Artemisia indica varied with different producing area and there was also difference for a certain constituent of the volatile oil. CONCLUSION: The study results serve as a scientific basis for rational use of Artemisia indica from Guangxi.

Abstract? AIM: To analysis the relation of severity of rhegmatogenous retinal detachment with the levels of amino acids and vascular endothelial growth factor ( VEGF) in the serum and in subretinal fluid.? METHODS: Forty -eight patients ( 52 eyes ) with rhegmatogenous retinal detachment treated in our hospital were selected.According to the degree of retinal detachment, patients were divided into <1/2 quadrant group, 1/2-3/4 quadrant group and>3/4 quadrant group. Fifty-five healthy objects for physical examination in our hospital were selected as the control group, to compare the differences of amino acids and VEGF levels in the serum.Correlation analysis on VEGF levels and amino acids in the serum and in subretinal fluid among patients with different grades of rhegmatogenous retinal detachment was conducted.? RESULTS: In patients with rhegmatogenous retinal detachment, the tryptophan in serum was 28.59±4.46mg/L, phenylalanine 8.95 ±2.55mg/L, methionine 8.15 ±2.17mg/L, valine 28.62 ±5.29mg/L, histidine 18.96 ±1.85mg/L and VEGF 589.92 ±185.34μg/L, which were higher than those in the control group, and the difference was statistically significant(P<0.05).The levels of phenylalanine was 9.85 ±1.21mg/L, histidine 20.63 ±2.07mg/L and VEGF 718.69 ± 283.34μg/L in the subretinal fluid of>3/4 quadrant group, which were significantly higher than those in the <1/2 quadrant group and 1/2-3/4 quadrant group ( P<0.05). VEGF in the subretinal fluid of VEGF in the rhegmatogenous retinal detachment group were positively correlated with phenylalanine (r=0.542, P<0.001), and histidine (r=0.782, P<0.001).?CONCLUSION: The levels of amino acids and VEGF in the subretinal fluid of patients with rhegmatogenous retinal detachment was higher than those in normals and increased with the severity of retinal detachment.

Objective To observe imaging characteristics and changes of vivo two-dimension multi-voxel proton magnetic resonance spectroscopy (~1H-MRS) in the rabbit models of VX2 hepatic carcinoma after high intensity focused ultrasound (HIFU) treatment. Methods VX2 hepatic carcinoma models were established in 20 New Zealand rabbits. Routine MR and 2-dimentional ~1H-MRS scanning were performed before and after HIFU treatment. The central regions of interest (ROI) of the VX2 tumor, tumor border and paratumor normal liver tissues were selected. The Cho/Cr and Lip/Cr of the same ROI before and after HIFU treatment were compared. Results Total 28 satisfied spectrogram diagram of ~1H-MRS were brought into statistical analysis. Of all the spectra, 6 metabolite peaks were detected as lipids (Lip), glutamine and glutamate complex (Glx), choline (Cho), lactate (Lac) and creatine (Cr). Cho and Lac peak in tumor center and tumor border regions after HIFU treatment were higher than those before HIFU treatment. Lip peak was lower than before, and major metabolites of paratumor normal liver tissues did not changed significantly. Statistical differences of Cho/Cr and Lipid/Cr of tumor center and border region were found between before and after HIFU treatment (P＜0.05). Conclusion Two-dimension multi-voxel ~1H-MRS can reflect major changes in the level of metabolites of different ROI for hepatic VX2 carcinoma after HIFU treatment.

Objective:To observe autophagy induced by aminophylline in human peripheral blood T lymphocytes.Methods:Peripheral blood T lymphocytes from health adults were separated with Percoll(1.073 g/ml) and harvested by using nylon column.The cultured cells were divided into control group,aminophylline group(10-8～10-3mol/L,or 0.001 8～180 ?g/ml)and dexamethasone(DXM) group,and the rates of autophagy and apoptosis were analyzed by flow cytometry.Results:①The purities of T lymphocyte were 81.3%～94.5%。②In control group for 72 h cultivation,the autophagic rate of T lymphocytes was significantly lower than those of 10-5～10-3mol/L aminophylline group(P0.05);In 10-5mol/L aminophylline group,the autophagic rate of different T lymphocyte density after cultivation(0,24,48,72 h) had a tendency of increase along with time lasting and decrease of cell density,but the difference did not show significance.③There was significant statistic difference in incidence rate of apoptotic T lymphocytes between control and DXM group in 72 h cultivation(P=0.000);But there was no significant statistic difference in the rate of autophagic(P=0.481).Conclusion:10-3～10-5mol/L aminophylline can induce autophagy in peripheral blood T lymphocytes,10-3～10-8mol/L aminophylline could induce both autophagy and apoptosis,and there is no significant correlation between autophagy and apoptosis;DXM can induce apoptosis in peripheral blood T lymphocytes,which indicates different programmed cell death of T lymphocytes could be induced by different medicines.
