A variety of extra-cellular signals could activate the target molecules and induce the associated biological effects depended on different signal pathways. Apoptosis, or programmed cell death, is a conservation process essential for normal development and homeostasis of biologist. It's known that a number of factors and pathways can lead to apoptosis. Specific phosphorlipids and proteins of biomembrane could activate the signal cascades of apoptosis. The interaction of caspases, bcl-2 family and mitochondria play an essential role in regulation of apoptosis.

Objective To observe the relationship between homocysteine (Hcy),C-reactive protein (CRP) and type 2 diabetes peripheral vascular disease (PVD).Methods Fifty-eight patients with type 2 diabetes according to the condition of PVD were divided into simple type 2 diabetes mellitus group (DM group,30 cases) and PVD group (28 cases).Twenty-five healthy people were chosen at the same period as control group.The fasting blood glucose (FBG),glycosylated hemoglobin (HbA1c),total cholesterol(TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C),Hcy and CRP levels were detected among 3 groups,and the body mass index (BMI),ankle brachial index(ABI) was calculated.Results The BMI,TG,TC and HDL-C levels among 3 groups had no statistical significance (P ＞0.05).The FBG,HbA1c and LDL-C in DM group and PVD group were significantly higher than those in control group [(7.54 ± 1.25),(8.12 ± 1.57) mmol/L vs.(4.68 ±0.54)mmol/L; (6.92 ± 0.89)％,(7.54 ± 0.97)％ vs.(4.80 ± 0.54)％ ; (3.79 ± 0.73),(4.41 ± 0.93) mmol/L vs.(2.68 ± 0.54) mmol/L],and the difference was statistically significant (P ＜ 0.05).But the difference between PVD group and DM group had no statistical significance (P ＞ 0.05).Hcy and CRP in DM group and PVD group were higher than those in control group [(10.26 ± 3.62),(19.83 ± 5.54) μ mol/L vs.(8.92 ± 2.41)μ mol/L; (4.12 ±0.57),(5.47 ±0.85) mg/L vs.(2.73 ±0.54) mg/L],ABI was lower than that in control group(0.92 ± 0.18,0.81 ± 0.16 vs.1.02 ± 0.23),and the difference was statistically significant (P ＜ 0.05);Hcy,CRP in PVD group were obviously higher than those in DM group,ABI was lower than that in DM group,and the differences were statistically significant (P＜ 0.05).Spearman analysis showed that Hcy was negatively correlated with ABI (r =-0.635,P ＜ 0.05),CRP was negatively correlated with ABI (r =-0.529,P ＜ 0.05),and Hcy was positively correlated with CRP (r =0.528,P ＜ 0.05).The partial correlation analysis results showed that Hcy and ABI still showed a negative correlation (r =-0.315,P ＜ 0.05),CRP and ABI still showed a negative correlation (r =-0.243,P ＜ 0.05).Conclusion Hcy and CRP participating in the occurrence and development of type 2 diabetes PVD,can be used as a predictor of type 2 diabetes PVD.

Objective To analyse the clinical effect of Quantianma capsules combined with flupentixol and melitracen tablets on chronic migraine. Methods 130 patients with chronic migraine were treated with flupentixol and melitracen tablets, were divided into control group and observation group, 65 patients in each group. The observation group were given to Quantianma capsules. Results The effective rate of observation group with 90.77% was higher than control group with 73.85%(P<0.05). After treatment, the number of migraine attacks, duration time, VAS score, HAMA and HAMD score and mean flow velocity of cerebral artery of two groups were lower than pre-treatment and observation group were lower than that of control group(P<0.05). Adverse reactions were similar in the two groups. Conclusion Quantianma capsules can improve the efficacy of treatment of chronic migraine combined with flupentixol and melitracen tablets and improve condition with few adverse effects.

OBJECTIVETo investigate the semen quality of cancer patients and search for a better way of sperm cryopreservation for them.

METHODSWe retrospectively analyzed the quality of the semen from 43 cancer patients under cryopreservation in the Sperm Bank of Zhejiang Province, and compared the semen parameters between the cancer patients and 248 normal donors as well as between the testicular cancer cases (n=22) and non-testicular cancer cases (n=21).

RESULTSThe cancer patients exhibited significantly lower semen quality than the normal donors as in sperm concentration (60.90 x 10(6)/ml vs 74.27 x 10(6)/ml), progressive motility (41.07% vs 51.79%), and recovery rate (49.98% vs 57.33%) (all P <0.05). Furthermore, the progressive sperm motility and sperm recovery rate after freezing were significantly decreased in the testicular cancer cases (15.68% and 42.81%) than in the non-testicular cancer cases (28.36% and 57.53%) (both P <0.05).

CONCLUSIONSemen quality declines in cancer patients, and therefore early sperm cryopreservation is essential for them. Due to the poor sperm motility and recovery rate of testicular cancer patients after freezing, further investigation is required on the improvement of sperm cryopreservation methods.

·AIM: Impairment of choroidal perfusion was found in AMD patients. We postulated that vasoactive agents,which can reduce choroidal blood flow resistance, might prevent the development of choroidal neovascularization (CNV). D-Timolol and L-Timolol are hypotensive agents used in cardiovascular and glaucoma therapy. Their effects on laser-induced experimental CNV rat model and human umbilical vein endothelial cells (HUVEC) were thus evaluated.·METHODS: Male Brown Norway rats were anesthetized to receive Nd:YAG laser to break the Bruch's membrane. D-Timolol and L-Timolol were given once daily through intraperitoneal injection after laser treatment for 4wk. Fluorescein angiography was performed on 2wk and 4wk. HUVEC were tested by proliferation assay and adhesion assay with D-Timolol and L-Timolol at different concentrations.· RESULTS: D-Timolol reduced the fluorescein leakage to 83% of the control group in laser-induced rat's CNV model at a dosage of 15mg/(kg·d). L-Timolol had no effect on CNV formation even at a higher dosage of 20mg/(kg·d). D-Timolol inhibited the endothelial cells proliferation significantly by 300mg/L. L-Timolol also significantly inhibited the cell proliferation at 1 000mg/L. But at a lower dose such as 300mg/L, no significant inhibitory effect was found. Both drugs showed no effect on cell adhesion function in cell culture experiments.· CONCLUSION: D-Timolol was found to prevent CNV development in laser-induced model in vivo and inhibit vascular endothelial cells proliferation in vitro. L-Timolol had no effect on cell proliferation at the same dose, and neither on rat CNV model. The results indicate these two isomers have different functions on rat's CNV prevention and on HUVEC cell proliferation.

AIM:To investigate the changes of visual development produced by monocular atropinization in rats.
METHODS: Twenty normal SD rats were randomly divided into two groups: control group ( n = 10 ) and atropinization ( experimental) group ( n=10 ) . All the left eyes were selected as the experimental eyes, and the right eyes served as the normal eyes. The left eyes in atropinization group was produced by 1% atropine, 3 times a day and the right eyes in control group was treated with normal saline, 3 times a day. The flash visual evoked potentials ( F-VEP ) and retinoscopy refraction of the rats'both eyes were detected at five time points:0, 7, 14, 21, and 28d after atropinization, respectively. After 28d, six rats were randomly selected from both groups and each group had three rats. The expression of the c- fos mRNA was observed in both visual cortexes. Another six rats were chosen for the same test after 2d dark environment with 2h light later. The expression of c-fos mRNA was detected again.
RESULTS: After 14d anisometropia was observed in experimental group, the difference was 3. 9D ( P<
0.0 5 ) , F-VEP P1 wave of the rats left in experimental group was reached to 88. 9±1. 889ms at 21d, there was statistical difference compared with the right eye ( P<0.05). After 28d, c-fos mRNA expression in the left visual cortex of rats in the experimental group was higher than that of the right side, but there was no significant difference. But when underwent 2h light stimulation after in the darkroom 2d, the c-fos mRNA expression in in the left visual cortex of rats in the experimental group was 5 times higher than that of the right side, there was a statistically significant difference (P<0. 05).
CONCLUSION: In the critical period of visual development, monocular chronic atropine in rats can form anisometropia, may delay the transmission of the optic nerve, hinder the normal development of the visual cortex. Monocular atropinization in rats can be used as the model of anisometropia.
