Insulin resistance is the fundamental defect of type 2 diabetes and often leads to hyperinsulinemia, which is associated with atherosclerosis and cardiovascular events. A multidisciplinary approach involving multifaceted therapeutic strategies is necessary to reduce cardiovascular events and to improve prognosis in these patients. The purpose of this review is to outline proven and promising therapeutic strategies for improving the long-term cardiovascular prognosis of patients with type 2 diabetes.

Fragile X syndrome is a common cause of inherit mental retardation,GABAA receptors are the major inhibitory neurotransmitter receptros in the mammalian central nervous system, implicated in anxiety,depression, epilepsy, sleeping problem, learning and memory, and so on. Several researches indicated that the GABAergic system, in particular the GABAA receptors might be related to the phenotype of fragile X syndrome. An altered expression of certain subunits of the GABAA receptors may cause the neurological and behavioural changes of the fragile X syndrome. Therefore,the GABAA receptors can be a novel therapeutic target for treatment of fragile X syndrome.

Objective To screen a kind of solid culture medium without animal-derived materials for resuscitating Streptococcus pneumoniae(Spn).Methods Spn 19F was selected for the preliminary screening of 9 kinds of formula culture media without animal-derived materials,and then other 23 serotypes of Spn were cultured for verification.The effect of the selected medium on the hereditary stability of various serotypes was identified by strain identification and capsular polysaccharide antigen gene sequence analysis of the 15-generation strains.The strains resuscitated by this medium were fermented according to the production procedure,and the culture situation and the yield and quality of capsular polysaccharide antigen were analyzed to determine the production applicability of the screened medium.Results The number of viable bacteria of various types of Spn was desired after 11～15 h of incubation on the selected solid medium and there was no difference in strain identification and antigen gene sequence between the final 15 generation and the control(strains cultured in sheep blood solid medium).After fermentation and culture of the strain resuscitated by this medium,the cell growth and the capsular polysaccharide production increased slightly,and all the related verification indicators of capsular polysaccharide met the requirements in Chinese Pharmacopoeia(Volume Ⅲ,2020 edition).Conclusion The selected solid culture medium without animal-derived materials has good applicability and can replace blood-derived culture medium for the resuscitation of Spn strain for vaccine production.

The restriction between distance and velocity measurement in medical Doppler ultra-sound is first proposed in this paper.The reasons resulting in this restriction are also analysed.Then our method to estimate blood flow velocity profile is introduced,in which the restriction is avoided.The discussion of this restriction in medical Doppler ultrasound and the method to detect blood flow velocity profile are finally presented.

As introduced in the paper, the average days of stay of clinical department were calculated as a management target, in view of the complexity of disease and case mix index. This method could avoid the deficiency of traditional methods and make the management of average length of stay of clinical department more conforming to the actual situation, and also more scientific and reasonable.

Objective:To observe clinical therapeutic effect of Xintong Injectio on angina pectoris of coronary heart disease.Methods:The patients of treatment group were treated by intravenous dipping of Xintong Injectio,and the control group by Isosorbide mononitrate,and changes of their clinical symptoms,signs,ECG,dynamic ECG,hemorheological indexes,blood lipids and other indexes were investigated.Results:The total effective rate was 95% in the treatment group and 65% in the control group,and the total effective rate for ECG was 76.67% in the treatment group and 48.33% in the control group,with significant differences between the two groups(both P

Objective To study the change of the peripheral blood cells of soldiers in high altitude hypoxia,to analyze its influ-ence on the blood cells.Methods The blood cell were compared among the soldiers in the plains,entered plateau after 6 months and stationed plateau for a long time,and to analyzed the effect of high altitude hypoxia environment on blood cells.Results WBC, RBC,hemoglobin,hematocrit and mean corpuscular hemoglobin concentration were obviously above plain group and long staff group (P <0.05),and mean corpuscular volume was obviously lower than those of plain group and long staff group (P <0.05).White cell and lymphocytes in plateau group were also obviously higher than those in plain group (P <0.05),and long staff group no signifi-cantly differences (P >0.05).platelet,mean platelet volume,platelet distribution width was clearly higher than that of plain group (P <0.05 ).Conclusion Blood cells of soldiers training in the high altitude hypoxia environment are significantly increased,and changes in blood cells are closely related to emplacement time and altitude.

Objective To investigate clinical value of the emergency endoscopic sclerotherapy and tissue adhesives embolization on patients with gastroesophageal varices bleeding. Methods A retrospective analysis of 52 cases of esophageal variceal bleeding in patients with clinical data was performed. Of which,22 patients were given conservative treatment alone and they were served as conservative treatment group. Another 30 patients were given the emergency endoscopic sclerotherapy and/ or tissue adhesive embolization besides the basis of conservative treatment,and they served as endoscopic treatment group. The data of hospitalization and mortality,rebleeding rates were recorded during hospitalized time and 1 year off hospitalization. Results The indices of hospitalized periods in endoscopic treatment group was( 16. 2 ± 1. 5)d,shorter than that in conservative treatment group((17. 6 ± 2. 1)d,P = 0. 53). The mortality and rebleeding rate in endoscopic treatment group in followed up periods were 3. 3% and 6. 6%,lower than those in conservative treatment group (9. 1%,13. 6%),and the comparison of relative risk RR of two groups of mortality and rebleeding rate were 2. 76 and 2. 06. Conclusion The therapy of emergency endoscopic sclerotherapy and tissue adhesives embolization of bleeding esophageal varices shows a good effect and it is worth recommending.

Objective To improve cost data acquisition mode for high efficiency in cost data management and advancement in hospital information construction. Methods A cost data acquisition system was developed independently on the foundation of HIS for the conversion from handcraft collection to system collection. Results Collection,storage,analysis and evaluation of the data in cost management system were realized and technical safeguard was offered in cost accounting work. Conclusion The technical improvement can not only ensure work efficiency,but also have effect on saving energy and manpower.

0.05), but there is statistic difference between the two groups in estimating the involvement of cervical canal and the earlier surgical stage than clinical stage(P
