100% elevation of PKC activity in the retina, and administration of D ? tocopherol prevented the elevation of PKC activity and diabetes induced decrease of both Na + K + ATPase and Ca 2+ ATPase activities. D ? tocopherol achieved a complete prevention of augmented pericyte and endothelial cell profile areas and basement membrane thickening in the superficial and deep capillaries bed of diabetic retina but had no effect on blood glucose and HbA 1c . Conclusion Diabetes induced histopathological abnormalities are mostly mediated by PKC. D ? tocopherol reduces the ultrastructural lesions in retinal capillary bed induced by hyperglycemia.

Objective To investigate the protective effect of the myocaidial ischemic postconditioning on ischemic-reperfused myocardium of rat and its signaling mechanism.Methods Healthy SD rats weighing 250 to 300 g were divided into blank control(N) group,ischemiareperfusion(IR) group and postconditioning(Post) group.We measured heart coronary perfusion flow and myocardial infarct size of the rats in each group.The expression of phosphorylated protein kinase B(P-Akt) was detected by Western blot.The morphological changes of myocardial fibers and mitochondrial were observed under the transmission electron microscopy.Results More coronary flow and less myocardial infarction were found in Post group than those in IR group.The expression level of P-Akt was higher in Post group.The integrity of myocardial fibers and mitochondrial was better in Post group than IR group.Conclusion Postconditioning had a protective effect for the ischemic isolated rat heart.Akt activation might play an important role in its mechinism.

Objective: To study the protection of IL 1ra in cultured developing neuron injury following Mg 2+ free induced epileptiform discharges. Methods: Rat embryo cortical neurons cultured for 6 d and 17 d were directly exposed to Mg 2+ free media, or pretreated with IL 1 receptor antagonist or NMDA receptor antagonists before being exposed to Mg 2+ free media, and then returned to regular media.MTT assay was used to study mitochondrial function injury, laser scanning confocal microscope to measure [Ca 2+ ]i, and real time RT PCR to detect gene mRNA expression. Results:(1) MTT conversion rates were higher in neurons pre and co treated with 10 mg/L IL 1ra than those of neurons with only Mg 2+ free treatment in neurons cultured for 17 d, but not in neurons cultured for 6 d.(2) [Ca 2+ ]i was lower in neurons pre and co treated with 10 mg/L IL 1ra than those of neurons with only Mg 2+ free treatment, either in neurons cultured for 6 d or in neurons cultured for 17 d, and the effects of IL 1ra on [Ca 2+ ]i change were different between neurons cultured for 6 d and neurons cultured for 17 d.(3) Pre and co treated with 10 mg/L IL 1ra NR1 mRNA expression increase induced by Mg 2+ free treatment was decreased, either in neurons cultured for 6 d or neurons cultured for 17 d, and this effect showed no difference between neurons cultured for 6 d and 17 d; Pre and co treated with 10 mg/L IL 1ra NR2A mRNA expression increase induced by Mg 2+ free treatment in neurons cultured for 17 d was decreased, and NR2A mRNA expression showed no difference between IL 1ra group and age matched control group, but have no effect on neurons cultured for 6 d; Pre and co treated with 10 mg/L IL 1ra have NR2B mRNA expression increase induced by Mg 2+ free treatment was not affected, either in neurons cultured for 6 d or neurons cultured for 17 d. Conclusion:Neuroprotection of IL 1Ra in seizure induced injury is age dependent. The mech anism of the neuroprotection of IL 1Ra includes down regulation of [Ca 2+ ]i and others.

Objective To investigate the genotype in Chinese patients with nonclassical 21 hydroxylase deficiency (NC 21OHD). Methods Eight patients with NC 21 OHD, 35 patients with classical one and 20 normal controls were studied as followed: CYP21 gene was amplified into fragment 1 (exon1→exon3) and fragment 2 (exon3→exon10) through PCR with specific primers. Second round PCRs were performed using fragment 1 and 2 as template, and PCR products were digested by restrictive endonucleases to analyze mutations by 3% 4% agarose gel electrophoresis. Results (1) The most frequent mutation in 8 cases of Chinese NC 21 OHD was P30L(6/16,37.5%), followed by V281L(4/16,25.0%). NC 21 OHD also carried mutations causing moderate or severe degree of enzymatic compromise, such as i2g (3/16, 18.8%), Q318X and R356W (1/16, 6.3% respectively), and I172N (3/16, 18.8%). (2) In ACTH 1 24 stimulation tests of 8 NC 21 OHD patients, basal 17 OH progesterone level was (23.9?28.4)?g/L and stimulated 17 OH progesterone level was (92.0?83.7)?g/L. (3) Genotype had strong correlation with phenotype in 21 OHD patients. Conclusion (1) As compared with caucasians, the most frequent mutation in Chinese NC 21 OHD is P30L, not V281L. (2) Much more attention should be paid to patients with hyperandrogenism to screen NC 21 OHD.

Background and purpose. Chemotherapy is a standard treatment for patients with advanced stage non-small cell lung cancer (NSCLC) However, platinum based chemotherapeutic regimen haves high toxicity profile to normal tissues. Lobaplatin (LBP) is a new third-generation antitumour platinum drug. Studies abroad have shown that Iobaplatin has an anticancer activity similar to cisplatin with better tolerance and is more effective for those who are resistant to cisplatin. This study was aimed to observe the effectiveness and toxicities of lobaplatin combined with vinorelbine (NVB) for the treatment of advanced NSCLC. Methods: Sixty-four patients pathologically diagnosed as clinical stage Ⅲ_B-Ⅳ NSCLC who did not receive treatment before, were randomly assigned to two groups. NL group (NVB+LBP): LBP at a dose of 30 mg/m~2 intravenous infusion on day 1, and NVB at a dose of 25 mg/m~2 intravenous infusion on days 1 and 8. NP group (NVB+DDP): Cisplatin (DDP) at a dose of 30 mg/m~2 intravenous infusion on day 1, 2 and 3 and NVB at a dose of 25 mg/m~2 intravenous infusion on days 1 and 8. Treatments were repeated every 21-28 days for 3 cycles. Results: For 34 patients of NL group, there were CR (1 cases), PR(13 cases), NC(15 cases), and PD(5 cases). The overall response rate (RR) was 41.2%, disease control rate (DCR) was 85.3%. In NP group: RR was 43.3%, DCR was 83.3% (X~2=0.05, P>0.05). Median overall survival time was 8.6 months and 8.9 months for NL group and NP group, respectively. The main toxicities in NL group were myelosuppression. Digestive toxicity such as anorexia, nausea,vomiting were less than those in the NP group (X~2=7.43, P<0.05), Peripheral hour,toxicity, serious liver and renal toxicity were not observed in NL group. Conclusion: Compared with cisplatin plus vinorelbine, domestic lobaplatin with vinorelbine yielded similar efficacies for NSCLC, but had less toxicity and well tolerate.

Objective This study describes the protective effect of myocardial isehemic post- conditioning on ischemic-reperfused myocardium (I/ R) of diabetic rat and its Signaling mechanism. Methods Healthy SD rats weighing 25O-30Og were divided into 6 groups; (1) Blank control; (2) Ischemia-reperfusion; (3) Post conditioning; (4) Diabetic postconditioning ; (5) Diabetic ischemia-reperfusion; ( 6) Diabetic blank control group. Ten rats in each group were randomly selected. Introduction of diabetic rat model: 65 mg/kg STZ was injected into the intraperitoneal cavity, until 2 consecutive blood glucose measurements≥ 16.65 mmol/L were reached after48h. The diabetic model was successful when rats had following symptoms, such as more drinking, more eating, polyuria, weight loss and epilation. Langendorff isolated rat heart perfusion was used for the experiment. Following parameters were measured and compared: Coronary perfusion flow, myocardial infarct size, western blot for measurement of P-Akt, changes in myocardium and mitochondrian observed by Electron microscopy. Results Blood glucose concentration in diabetic group was (23. 15±2. 16) mmol/L and (4. 16±0. 31) mmol/L in non-diabetic group. There was a significant difference (P <0. 01) between the two groups. There were more coronary flow in post-conditioning groups (Post group and Dpost group) than ischemia-reperfusion groups (IR group and DIR group) (6.5±1.2、5.6±1.0 vs. 3.4±1.0、2.0±1.3). The myocardial infarction size was smaller in post-conditioning groups than in ischemia-reperfusion groups (25.2±2.1、34.2±3.6 vs. 47.5±3.5 、65.2±4.5). There was more expression of P-Akt and the myocardial fibers and mitochondrian in post-conditioning groups were better preserved. Conclusion Postconditioning has protective effects in diabetic rat hearts. The mechanism may be associated with Akt activation.
