BACKGROUND: Interleukin-17A has been shown to play an important role in nerve regeneration following corneal injury. OBJECTIVE: To investigate the effect of interleukin-17A on mouse nerve regeneration after optic nerve injury.METHODS: The interleukin-17A-overexpressed adenovirus vector (AV-IL-17A-GFP) was constructed and purified. Adenoviruses with green fluorescent protein (AV-GFP) served as control group. PC12 cell lines were transfected with adenoviruses and the expression efficiency of IL-17A were detected by ELISA. The adenovirus was intravitreally injected into the mouse vitreous body, and the expression level of IL-17A in the optic nerve was determined by immunofluorescence. Afterwards, a mouse model of optic nerve injury was established to observe the nerve regeneration. RESULTS AND CONCLUSION: ELISA results showed that IL-17A was highly expressed in the PC12 cell lines transfected with AV-IL-17A-GFP compared with the control group.Immunofluorescence results revealed that IL-17A was expressed in vivo successfully.There was a significant increase in the number of regenerated axons in the AV-IL-17A-GFP group compared with the control group (P < 0.05). To conclude,AV-IL-17A-GFP can be expressed in the mature neurons in vivo and promote the axon regeneration after optic nerve crush injury in mice.

Objective To investigate the effect of Ang-(1-7) on the apoptosis in human umbilical vein endothelial cells (HUVECs) induced by Ang Ⅱ.Methods HUVECs were isolated and cultured.Cultured HUVECs were incubated for 24 h with Ang-(1-7), Ang Ⅱ, Ang-(1-7) A-779, Ang-(1-7) + Ang Ⅱ, A-779 + Ang Ⅱ + Ang-( 1-7), respectively.Cultured HUVECs without incubating stimulator were chosen as controls.The apoptosis of endothelial cells were detected by flow cytometry.Results The apoptosis of endothelial cells in HUVECs were upregulated by AngⅡ ( 10-6 mol/L) (25.60% ±3.17% vs 2.32% ±0.24%, P ＜0.005).Compared with the AngⅡ group, Ang-(1-7) dose-dependently inhibited the apoptosis of endothelial cells in HUVECs ( (20.04% ± 2.21% ,16.04% ± 1.32 %, 10.04% ±2.05,7.79% ±1.50% vs AngⅡ group 25.60% ±3.17%, P ＜0.05 , P ＜0.05).The effects of Ang-(1-7) could be blocked by A-779 (23.37% ±0.75% vs 20.04% ± 2.21%, 16.04% ± 1.32,10.04% ± 2.05% ,7.79%± 1.50%, P ＜ 0.05 ).Conclusion Ang-(1-7) can attenuate the apoptosis of endothelial cells induced by Ang Ⅱ in HUVECs in a dose-dependent manner.The effects of Ang-(1-7) could be blocked by A-779( P＜0.05).

OBJECTIVETo investigate the effects of hydrogen sulfide (H₂S) on oxidative stress and endoplasmic reticulum stress (ERS) in a rat model of diabetic cardiomyopathy (DCM).

METHODSThirty male SD rats were randomly divided into control group, diabetes group and treatment group( n = 10). Intraperitoneal injection of streptozotocin was utilized to establish a rat model of DCM. The rats with DCM in treatment group were intraperitoneally injected with NaHS solution. After treated for 12 weeks, the hearts isolated from rats were perfused on a langendorff apparatus. The ventricular hemodynamic parameters were measured. The ultrastructures of myocardium were observed using electron microscopy. The content of malondialdehyde (MDA), the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in myocardial tissue were determined by spectrophotometry. The expressions of C/EBP homologous protein( CHOP), glucose-regulated protein 78 (GRP78) and Caspase 12 at mRNA level in myocardium were detected using RT-PCR.

RESULTSCompared with control group, the cardiac function and myocardial ultrastructure were damaged obviously in diabetic rats. In myocardial tissue, the content of MDA was increased, while the activities of SOD and GSH-Px were decreased. CHOP, GRP78 and Caspase 12 mRNA expressions were increased significantly. Compared with diabetes group, cardiac function and myocardial ultrastructure damage were improved in treatment group. The content of MDA was decreased, while the activities of SOD and GSH-Px were increased significantly. The mRNA levels of CHOP, GRP78 and Caspase 12 were increased.

CONCLUSIONH2S can protect myocardium in diabetic rats, maybe it is related to reduce oxidative stress damage and inhibition of the ERS-induced apoptosis pathway.

Objective To investigate prevalence and risk factors of peripheral artery disease (PAD), metabolic syndrome (MS) and peripheral artery disease complicated with metabolic syndrome among Kazakh adults lived in Xinjiang Yili prefecture. Methods Four-stage cluster sampling method was used to select adults aged 35 years and over for the study from six cities and prefectures of Xinjiang. All the participants were interviewed with questionnaire to collect their demographic characteristics. Physical checksup and blood biochemical measurements were performed for all of them, as well as blood pressure was measured in their lower legs and arms to calculate ankle brachial pressure index ( ABPI), a ratio of the blood pressure in the lower legs to that in the arms. Only data of Kazakh adults in Yili prefecture were analyzed in this paper, including prevalence and risk factors for PAD and MS, as well as their relationship.The patients with PAD were divided into two groups, one complicated with MS and the other without it Logistic regression analysis was used to identify potential risk factors for PAD and MS and their combination.Results A total of 1365 adult Kazakh people were surveyed. Prevalence of MS was 23.7 percent, 30.4 percent for men and 19.0 percent for women, respectively, and that of PAD was 9. 4 percent, 7.0 percent for men and 11.0 percent for women, respectively. Mean age in patients of PAD complicated with MS was older than that in those without MS (t=-5.348, P＜0.01). Risk of PAD complicated with MS in Kazakh people associated with gender ( men), age, systolic pressure, diastolic pressure and blood glucose level.(P＜0.05). Conclusions Both prevalence of PAD and MS are significantly higher among Kazakh people in Yili prefecture of Xinjiang, and increase with age. Prevalence of PAD is significantly higher in those with MS than that in those without MS. Risk factors of PAD complicated with MS include gender(men), age,systolic pressure, diastolic pressure and blood glucose level.

The study is aimed to understand the resource and the current situation of the use of Cibotii Rhizoma and provide the basis for protecting and utilization. The method of literature survey, field survey and quality assessment were applied in the study. The results showed that all the Cibotii Rhizoma came from wild resource and was mainly founded in Fujian, Guangxi, Guizhou, Yunnan, Guangdong, Hunan, Jiangxi, Sichuan, Chongqing, Zhejiang, etc. It contains over 5 000 000 kg in the area which total is about 7 000 hm2. The annual output is over 850 000 kg. At present, there is no cultivated resources. Based on the investigation and market sampling analysis from various regions, the results showed that the quality of the collected crude drugs conformed with the regulations of the Chinese pharmacopoeia. However the qualification rate of decoction pieces of Cibotii Rhizoma in market was only 56.4%. At present, the resource of Cibotii Rhizoma could meet the needs of medinal uses. It is important to protect the wild resource which is less and less because of the environmental factors. It also need to make a standard of processing method to ensure the safety, and solve quality problem of the decoction pieces.
