1.Exploratory analysis about neuroprotection after ischemic stroke
China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(12):-
To mitigate penumbra injury is the key factor in the treatment ofischemic stroke.Blood reflow and neuroprotection against time are premise to achieve this.Due to time window, thrombolysis rate is low(less than 5% in developed country).However, all neuroprotectants haven't been demonstrated to be effective in human, till now.Based on guidance ofwholism concept ofTCM and analysis ofrelative studies in western medicine.We found that functional status ofnon-ischemic areas can impact on injury degree offocal ischemia.One ofthe reasons that lead to failure in neuroprotective studies may be without considering this impaction.We put forward that non-ischemic areas can impact on the injury degree ofischemic area through the complex neuronal network, and effective regulating the functional status ofnon-ischemic areas is one ofthe key factors which can ameliorate focal ischemic injury.

Objective This study was designed to investigate the relationship between programmed cell death 5 (PDCD5) and endometrial carcinoma .Methods 60 tissue samples of endometrial carcinomas ,40 normal proliferative endometrium tissues and 28 endometrial atypical hyperplasia tissues were obtained from patients who underwent operation.The expression of PDCD5 was detected by Real-time PCR and immunohistochemical analysis . Results In normal proliferative endometrium , atypical hyperplasia tissues and endometrial carcinoma , the PDCD5 mRNA was gradually decreased[(1.21 ±0.16),(0.83 ±0.07),(0.42 ±0.02),F=5.637,P<0.05];The posi-tive rate of protein was gradually decreased (82.5%,64.3%,45.0%,χ2 =27.663,P<0.05);The expression of PDCD5 was correlated with TNM stage , histological grade , depth of myometrial invasion and lymphatic metastasis (χ2 =20.875,11.915,9.409,11.148,all P<0.05),but was not correlated with ages (χ2 =0.287,P>0.05). Conclusion PDCD5 might become a potential molecular marker of early diagnosis of endometrial carcinoma .

Objective:To explore the effects of total saponins of Cornus offlcinalis Sieb.(TSCO) on the contractility and relaxation of mesenteric artery in streptozotocin (STZ)-induced diabetic rats.Methods:Sprague Dawley rats were administrated STZ intra-peritoneally at a dosage of 60 mg/kg to induce diabetes.TSCO was administrated at a dosage of 60 mg/kg or 120 mg/kg (per os) to the diabetic rats for 28 days.Glucose and insulin in the serum as well as the responsiveness ofmesenteric artery rings were determined.Results:TSCO decreased the contractile responsiveness to phenylephrine of mesenteric artery rings from diabetic rats,but increased the reactivity to acethylcholine.TSCO (120 mg/kg) ameliorated the baseline release of nitric oxide of mesenteric artery,but had little effect on the induced release of nitric oxide.Rosiglitazone had less effect on the mesenteric artery function than that of TSCO,though it was more effective on lowering blood glucose.Conclusion:The effects of TSCO on mesenteric artery of diabetic rats are dose dependent,and are possibly exerted by lowering blood glucose and ameliorating the release of nitric oxide in the endothelium.

Traditional Chinese medicine(TCM) injection,which plays a unique role in the clinical treatment,is Chinese original dosage form.But in recent years due to its quality problems or unscientifically clinical use,some adverse reactions have reported,even several injections had serious adverse reactions.So how to develop TCM injection becomes one of the topics the public and scholars most concerned about.Therefore,the three "bottleneck" problems of TCM injection on the current development,which are the material basis and TCM theory,clinical efficacy and safety,and also quality control,were analyzed and discussed in the article.Then the countermeasures were proposed and provided ideas for future research and development of TCM injection.

Objective:To evaluate effect of simvastatin on neurons autophagy in the hippocampus following intracerebral hemorrhage( ICH) in rats.Methods:All rats were divided randomly into sham group;ICH group and SIM group.The rat model of ICH was made by injection of Ⅶ type collagenase.The behavioral changes were evaluated with Garcia′s neurologic deficit score.Wet-dry weight method was used to evaluate brain edema.Additionally,localization of LC3 protein was determined by immunohistochemistry, and the expression of Beclin-1 in hippocampus was tested by Western blot methods.Results: Compared with ICH group,simvastatin treatment after ICH significantly improved neurologic deficit score ( P<0.05 ) , reduced the water content of brain tissue ( P<0.05 ) , inhibited the expression of LC3 and Beclin-1 protein(P<0.05).Conclusion:Our findings indicated that administration of simvastatin had neuroprotective effects in ICH rat model,which could be involved in inhibiting activation of autophagy in the hippocampus,finally reducing brain edema and neurobehavioral deficit.

Objective:To prepare compound Xiaoshangtong spray films and establish an HPLC method for quality control. Meth-ods:Chitosan hydrochloride and PVP as the main film-forming materials, and HPMC as the film-forming assitant agent, the com-pound Xiaoshangtong spray films were prepared. Lidocaine and mupirocin were simultaneously determined by HPLC. A Hypersil ODS2 column(250 mm × 4. 6 mm, 5 μm)was used. The mobile phase was composed of 0. 5% ammonium dihydrogen phosphate-methanol (40∶60, adjusting pH to 6. 0 ± 0. 5 with sodium hydroxide). The flow rate of mobile phase was 1. 0 ml·min-1 and the temperature of the column was 30 ℃. The detection wavelength was 222nm and the injection volume was 20 μl. Results: The linear range of lido-caine was 25. 0-400. 0 μg·ml-1(r=0. 999 7) and the average recovery was 100. 14% (RSD=1. 21%,n=9). The linear range of mupirocin was 25.0-400.0 μg·ml-1(r=0.999 9)and the average recovery was 101.13%(RSD=0.57%,n=9). Conclusion:The preparation process is reasonable. The established determination method is accurate and reliable, and suitable for the quality con-trol of the compound Xiaoshangtong spray films.

Objective: The extract technologies for the components of Fuzhuang Capsules were optimized. Methods: Four methods: the semi bionic extraction (SBE), the water extraction (WE), the semi bionic extraction by precipitation with alcohol (SBAE) and the water extraction by precipitation with alcohol (WAE) were used to extract Fuzhuang Capsules, with panaxadiol, panaxatriol, ? sitosterol, icariine, betaine, total sugar and dried extractive taken as the marker, under the same conditions of drug granularity, solvent amount, decocting temperature, filtration, concentration, etc., and then four methods were compared and studied. Results: Through the comprehensive evaluation of seven markers, their comprehensive values Y decreased in the order of SBE, WE, SBAE and WAE. Conclusion: SBE is better than the other three methods in the extraction of the components of Fuzhuang Capsules, which is showed by the fact that the pH values of the water for the 1st, 2nd and 3rd decoctions are 3.4, 7.5 and 8.4, and the extraction times are 2.0h, 1.5h, and 1.5h respectively.

Objective To explore the effect of rehabilitation training on learning and memorial ability and long-term potentiation (LTP) in hippocampal region CA3 in rats with cerebral infarction. Methods 30 male rats were randomly divide into model group, rehabilitation training group and normal group with 10 cases in each group. Photochemical method was used to induce hippocampal infarction. The performance of Y-maze test and moving-back with current stimulation experiment were recorded. The increase rate of population spike (PS) in hippocampal region CA3 and PS latent period were compared. Results The frequency of training of Y-maze test was less after rehabilitation training, the latent period of moving-back with current stimulation experiment prolonged, and the PS latent period was shortened. Conclusion Rehabilitation training may strengthen the LTP effect in hippocampal region CA3, and improve the learning efficiency

Objective To investigate human papilloma virus(HPV) infection in normal endometrium, atypi-cal hyperplasia of endometrium and endometrial carcinoma. Methods By the nucleic acid hybridization,we detected 28 pairs of endometrial carcinomas, 21 pairs of atypical hyperplasia of endometrium. Normal endometrium from 16 pa-tients with uterine myomas were as control. Results HPV16/18 DNA was detected in 25 endometrial carcinoma and 2 atypical hyperplasia of endometrium and 1 normal endometrium. Conclusions Endometrial carcinoma HPV16/18 DNA were significantly higher than those infected with atypical endometrial hyperplasia and normal endometrium. Note the occurrence of endometrial cancer,the development may be associated with HPV infection.
