Objective:To observe the clinical efficacy of Xueshuantong combined with the conventional treatment and the impact on fibrinogen (FIB) and D-dimer in the patients at acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Meth-ods:Totally 218 cases of AECOPD inpatients were divided into the observation group and the control group randomly .The control group received the conventional therapy , while the observation group was intravenously treated with 250 mg Xueshuantong lyophilized powder dissolved in 250 ml 10%glucose injection additionally .The treatment course was 14 days.The changes of FEV 1 , FEV1/FVC, FIB and D-dimer in the two groups after the treatment were compared , and then the clinical efficacy of the two groups was evaluated . Results:After the treatment, the levels of FEV1 , FEV1/FVC, FIB and D-dimer in the two groups were significantly improved when compared with those before the treatment , and the changes in the observation group were more significant than those in the control group (P<0.05).The total effective rate of the control group was 80.73%, and that of the observation group was 89.91% (P<0.05). Conclusion:Anticoagulant therapy using Xueshuantong on the basis of the conventional therapy can significantly reduce the amount of fibrinogen and D-dimer serum fiber in AECOPD patients , which is helpful to improving the hypercoagulable and fibrinolysis state and the lung function of AECOPD patients .

Objectives To assess whether prodromal transient ischemic attack (TIA) has beneficial effects on type 2 diabetic patients and those had acute fasting hyperglycemia with the first-ever acute anterior circulation infarction.Methods One hundred and seventy patients with first-ever ischemic acute anterior circulation infarction were involved.According to whether they had type 2 diabetes mellitus,patients were divided into group A (non-diabetic patients) and group B (diabetic patients).Mean infarct volume was also compared between patients with pro-TIA and without pro-TIA in group A and B,and each group with acute hyperglycemia too.Results In group A,prodromal TIA was associated with a smaller infarct volume (M: 2.61 cm3 vs 5.99 cm33 Z=-2.69,P=0.007).On the contrary,in group B,there was no significant difference in infarct volume (M: 3.25 cm3 vs 11.0 cm3,Z=-1.699,P=0.08) between patients with and without prodromal TIA.In group A patients absent with acute fasting hyperglycemia,infarct volume significantly smaller in patients with prodromal TIA than in those without (M: 2.69 cm3 vs 6.46 cm3,Z=-2.34,P=0.019) ; In patients with acute fasting hyperglycemia,there was no a significant difference in infarct volume (M: 2.61 cm3 vs 5.69 cm3 ,Z=-1.218,P=0.27).However,among group B patients present or absent with acute impaired fasting glucose,there was no significant difference in infarct volume in patients with or without prodromal TIA.Conclusion Diabetes mellitus and the acute fasting hyperglycemia might prevent the ischemic preconditioning.

Objective To study the effect of motor imagery therapy combined with conventional physical training on hemiplegia lower extremity function in stroke patients with hemiplegia.Methods Thirty hemiplegic patients meeting the eligible criterions were randomly divided into two groups: a treatment group (n = 13 ) and a control group ( n = 17).All subjects accepted conventional rehabilitative treatment.Patients in treatment group were treated with motor imagery therapy after physical training, while the patients in control group were treated with physical training only.Motor function was measured by the percentages of changes in maximum loading on affected lower limb (PL%), Barthel index (BI), 5m maximum back and forth walking speed (5m MBFWS), Berg balance scale ( BBS), Fugl-Meyer motor assessment ( lower limb) (FMA-L) before the beginning of training and at the end of sixweek training.Results In both groups, all measurements at the end of training improved significantly ( P < 0.01 )compared to that at the beginning of training.After the whole training course, PL% and 5m MBFWS (m/s) in treatment group were significantly better compared to those in control group( P < 0.05 ), and the other measurements were not statistically significant between two groups( P > 0.05 ).Conclusion Motor imagery therapy had positive effect on hemiplegia lower extremity function of sub-acute stroke patients.

Objective To study the impact of therapy strategy on outcomes of patients suffering from severe sepsis and/or septic shock. Method A total of 195 patients diagnosed as severe sepsis or septic shock were enrolled for prospective study from June 2008 to December 2009. Patient's clinical manifestation,treatments and outcomes were studied by using SSC database. Patients were divided into control group and treatment group. In control group, patients enrolled from June 2008 to December 2008, were treated with conventional medical care In treatment group, patients enrolled from January 2009 to December 2009 were treated with a novel algorithm of mandatory treatment for sepsis In-hospital mortality of two groups was compared. SPSS15.0 software was used for analysis of data. Chi-square test and unpaired t-test were used for comparisons between groups. Results Compared to the control group The need for blood lactate test was significantly grown in treatment group [98.2% (115/117) versus 2.56% (2/78), P ＜ 0.001]. Antibiotics was administered to 69.2% (81/117) patients of treatment group within 3 hours after their arrival at the emergency department compared to 35.8% (28/78) in the control group (P ＜ 0. 001). Blood cultures made before antibiotics given were 47.9% (56/117) in the treatment group compared to the control group 25.6%(20/78), P = 0. 003. The rate of fluid resuscitation was 80.3% (53/66) in the treatment group and 27%(10/37) in the control group, P ＜0.001. The rate of CVP (8 mmHg was 27.3% (18/66) in the treatment group and 8.1% (3/37) in the control group, P = 0. 023. In-hospital mortality was 29.1% (34/117) in the treatment group and 44.8% (35/78) in the control group, P =0. 032. Conclusions The algorithm of mandatory treatment for sepsis improved the therapeutic efficacy of the treatment for severe sepsis and septic shock, decreasing in-hospital mortality.

Objective To discuss the influence of sex in gastric cancer via the epidemiology and clinical data analysis of gastric cancer patients. Methods The clinical data of 242 gastric cancer patients was collected from Shanxi provincial tumor hospital between 1997 to 1998. Every patient filled in gastric cancer epidemiology form by professional-staff direction, which included personal characteristics, food habits, farmalial history of cancer and other informations. Results The average age of male gastric cancer patients was 6 years older than the females'. Male ulcer type gastric cancer patients were more than the females' (120 vs 38, P < 0.01). There was no different in cell types, differentiation, tumor stage and the clinical pathological features of lymph node metastasis. Male alcoholic drinkers, tea drinkers and smokers were more than the females' . There was no different in sex in tumor familial history and dietary habits of water, well-done food, sour food, vegetables, fruits and amount of radiation of meats, eggs and milk. Conclusion This research reveals the characteristics of sex in the epidemiology of gastric cancer. It is very important and significant not only in the research of gastric cancer etiology, but also in the prevention and intervention of gastric cancer.

OBJECTIVE: To make an useful identification method for the molecule of DNA on 3 herbs of Artemisia genus and compare the differences of the genes of Korean and Chinese species of Artemisia. METHODS: Sequence of 3 herbs (Artemisia sacrorum Ledeb., Artemisia iwayomogi Kitam. and Artemisia capillaris Thunb.) was determined by PCR sequence system. DNA was extracted from rDNA/ITS (internal transcribed spacers) and 5.8 s. The analysis was based on the amplification through DNA sequence system. RESULTS: There were profound differences between the Korean Artemisia and Artemisia sacrorum L. These 2 herbs had a difference in the PCR amplifications of the agarose gel electrophoresis. There was a slight difference in the analysis of the DNA sequence system, and the substitution percentage for ITS gene fragments sequence was 3.96%. CONCLUSION: Analytic identification method on sequence system of ITS in rDNA is effective for these 3 herbs.

Purpose To investigate the effects of hypoxia inducible factor-2α (HIF-2ot) siRNA on proliferation and chemotherapy sensitivity of breast carcinoma MCF-7.Methods RNA interference was used to silence the expression of HIF-2α in MCF-7 cells.The changes of HIF-2α gene expression were detected by immunocytochemistry and RT-PCR.Under hypoxia environment simulated by CoCl2,MTT assay and flow cytometry (FCM) were used to measure cell growth inhibition rate and cell apoptosis of MCF-7 cells under different dosages of chemotherapeutic agents (5-fluorouracil,adriamycin,and paclitaxel).Results Expression of HIF-2α in MCF-7 were down-regulated by HIF-2α siRNA (P ＜ 0.05).The proliferation inhibition and apoptosis rates were evidently increased after transfection with HIF-2α siRNA (P ＜ 0.05),chemotherapy drug sensitivity was enhanced.Conclusion HIF-2α siRNA can induce the apoptosis and inhibit the proliferation and enhance the sensitivity of breast carcinoma MCF-7 cell line to chemotherapeutic agents.Blocking HIF-2α maybe a very promising strategy for breast carcinoma gene therapy in combination with chemotherapy.
