Anticoagulation, which has been used in clinical practice since 1940's, is one of the important measures in the prevention and treatment of cerebrovascular diseases. This article reviews the progress in anticoagulation for ischemic cerebrovascular diseases by introducing a series of large, important, international, randomized controlled clinical trials in the past 20 years (particularly in the recent 10 years).

The changes of skeletal muscle mitochondral monoamine oxidase (MAO) activity in rats fed with low Se grains from a Keshan-disease area were observed. The rats were killed at the time for feeding 30, 60 and 90 days respectiely. The mitochondrium of skeletal muscle was isolated MAO activity was determined with fluorescent methed. The results showed that in low-Se group the mitochondrial MAO activity was significantly decreased only at the time for 90 days feeding however GSH-px activity in red blood cells and Se content in plasma were significantly decreased at all experimental period as compared to Se-supplemented or stock died group.

Objective To investigate the diagnosis of value 99mTc-MIBI SPECT and CT fusion imaging in the differential solitary pulmonary nodule ( SPN). Methods Thirty-nine patients with SPN underwent 99mTc-MIBI-SPECT and positioning CT fusion imaging, and the imaging results carried on the qualitative and semi-quantitative analysis. The diagnostic value of the imaging method for SPN was judged according to the results of the final diagnosis. Results Of 39 cases with SPN, 13 cases were malignant and 26 cases were benign. The diagnostic sensitivity, specificity, accuracy, negative predictive value and positive predictive value of 99mTc-MIBI-SPECT positioning CT fusion imaging qualitative analysis in benign and malignant SPN was 92.31%(12/13),88.46%(23/26),89.74%(35/39),80% (12/15) and 95.83% (23/24),respectively. Receiver operating characteristic (ROC) curve analysis showed:using 99mTc-MIBI early uptake ratio (EUR) ≥1.474 as the critical value for identification the benign and malignant SPN, the sensitivity and specificity was 100% and 76.90%, respectively;using 99mTc-MIBI delayed uptake ratio (DUR) ≥ 1.38 as the critical value, the sensitivity and specificity was 100%and 76.90%. Conclusion The method of 99mTc-MIBI-SPECT and positioning CT fusion imaging has a high clinical value in the differential diagnosis of SPN.

Objective To investigate the effect of gastric filling degree on the thickness of advanced gastric carcinoma and the clinical value of the thickness measured by CT.Methods Totally 38 patients with advanced gastric carcinoma were enrolled and 21 patients were newly diagnosed,17 patients were reexamination after non surgical treatments.The stomach cavity was filled with oral gas-producing powder.The plain scanning (before filling) and enhanced scanning in venous phase (after filling) were performed.The thickness of the normal gastric wall and gastric carcinoma before and after filling were measured on axial images,and the differences were compared.The patients were measured again one month later by the same investigator,and the consistency between the twice measurements was evaluated.Results Before and after filling,the normal gastric wall thickness of each regions was significantly different (all P＜0.001),and the change was greatest at the region of greater curvature.Carcinoma thickness was similar in newly diagnosed patients (P＜0.05),but significantly different in patients for reexamination (P＜0.05).The twice measurements had a good consistency.Conclusion The thickness of gastric carcinoma can be considered as a baseline measurement indicator in newly diagnosed patients.It is critical to maintaining a similar gastric filling degree during reexamination,which is helpful to evaluate the efficacy of treatment accurately.

Objective To evaluate the health-related quality of life (HRQOL) and its influencing factors in pa tients with cervical cancer.Methods 120 inpatients with cervical cancer at Yunnan Tumor Hospital were investigated by functional assessment of cancer therapy-cervix (FACT-Cx),t-test,analysis of variance and multiple linear regression were used to analyze factors influencing the HRQOL.Results The total HRQOL score of patients was (104.88 ± 19.51),and the domain scores of physical well-being (PWB),social/family well-being (SWB),emotional well-being (EWB),functional well-being (FWB),cervical cancer subscale (CxS) were (20.41 ± 5.46),(17.17 ± 6.10),(15.73 ± 5.06),(13.34 ±5.83),(38.23 ±6.26),respectively.Based on multiple linear regression,the influencing factors of PWB were marital status and clinical stages,the influencing factor of SWB was marital status,the influencing factors of EWB were education levels and clinical stages,the influencing factors of FWB,CxS and total score were all marital status,clinical stages and education levels.Conclusions The HRQOL scores were influenced by a number of factors and it is significant to improve HRQOL in patients with cervical cancer by relieving symptoms and reducing treatment side effects according to patients' specialty,also psychological support and encouragement was essential.

Objective To investigate the distribution of pathogens isolated from clinical samples and the resistance to the com‐mon antimicrobial agents .Methods Of the 3 745 children ,Hand‐foot‐mouth disease was the most prevalent disease with 1 397 (37 .30% ) cases ,followed by the bronchopneumonia ,rotavirus enteritis and bacterial intestinal infection ;784 strains were isolated from the samples mainly including Haemophilus parainfluenzae (16 .20% ) ,Streptococcus pneumoniae (14 .92% ) ,Moraxella ca‐tarrhalis (12 .88% ) ,Staphylococcus aureus (10 .59% ) and Salmonella enterica(10 .8% ) ;The positive rate of Methicillin‐resistance Staphylococcus aureus(MRSA) was 27 .50% and the ESBLs producing Escherichia coli and Klebsiella pneumoniae were 46 .43%and 81 .40% ,and two or more pathogens could be isolated from sputum .Conclusion Haemophilu ,Streptococcus pneumonia and Moraxella catarrhalis are the main bacterial pathogens in the department of infectious .There is a certain resistance to the common antimicrobial agents .It is important for us to focus on the pathogens and we should pay more attention to the control the resistance of the bacteria .

Three groups of Sprague-Dawley rats were fed on low-Se diet frow Keshan disease area, Se-supplemented diet and stock diet respectively, for observing the effect of Se on mitochoadrial monoamine oxidase (MAO) activities in myocardia. The results showed that cardiac mitochondrial MAO activities in the Se-deficient group were significantly decreased as compared to both the Se-supplemented and stock diet group, and Se content in plasma and GSH-Px activity in. red blood cells also were significantly reduced at 30, 60 and 90 days of feeding. In Se-supplemented group MAO and GSH-Px activities as well as Se content were comparable to levels in the stock diet group.

Objective To explore correlation between alexithymia and resilience in military personnel.Methods 2802 subjects were chosen by random cluster sampling to outline the military personnel resilience scale and military alexithymia scale.The data were analyzed by t-test,chi-square test,ANOVA,correlation analysis and multiple linear regressions analysis.Results The prevalence rate of alexithymia was 6.85％,while resilience was 6.60％.Compared to sea force (45.62 ± 11.25 ) and air force (45.32 ± 9.98 ) subjects,land force (47.92 ± 9.92)had significantly higher total score in alexithymia(P＜ 0.05 ).Compared to sea force (87.35 ± 12.15 ) and air force ( 88.58 ± 10.39 ) subjects,land force ( 85.73 ± 10.70) had significantly lower total score in resilience(P ＜ 0.05 ).The total score and every factor score of subjects with alexithymia were significant lower than those of control group in resilience(P ＜ 0.05 ).Every factor of Resilience Scale were mild negative correlation with every factor of Alexithymia Scale (P＜0.01).Problem solving,volition,optimism and family supports were the main factors which had affected on the alexithymia.Conclusion The prevalence rate of alexithymia in military personnel is lower than ordinary people,but there are still issues in alexithymia and resilience,particularly in land force.The research show mild correlation between alexithymia and resilience in military personnel.
