DPP-4 inhibitors are new oral hypoglycemic drugs and hot spots developed and launched in recent years, and they pro-vide new choices for the clinical treatment of type 2 diabetes. In China, DPP-4 inhibitors that are approved to use in the treatment of type 2 diabetes are all imported products currently. In the paper, the current intellectual property situation of DPP-4 inhibitors that are developed and approved at home and abroad is researched and analyzed. Reasonable use of the patent information of DPP-4 inhibitors that is about to expire or have failed can provide good guidance for the subsequent development of DPP-4 inhibitors in domestic with promising curative effect and good market prospects, and can generate new patents in order to enhance the market competitiveness.

The autophagy is a process of cell survival by lysosomal degradation of damaged organelles and macromo-leular materials. It plays an important role in stable environment. The autophagy of cells is persisted in the patho-physiology of angiogenesis. However,To explore the development of the angiogenesis based on autophagy,is the clinical treatment ideas of the vascular disease.

Objective To investigate the current status of occupational hazards and prevention and control of occupational ， - Methods ， diseases in micro small and medium sized manufacturing enterprises in Jiangxi Province. A total of 1 034 micro - small and medium sized manufacturing enterprises in Jiangxi Province were selected as the research subjects using a stratified cluster sampling method. The exposure of occupational hazards and the implementation of occupational hazards prevention and Results ， control measures were investigated. Among the 1 034 enterprises the small and micro enterprises accounted for ， 91.5%. The enterprises with serious occupational hazards were mainly concentrated in metallurgy building materials industry ， and machinery equipment and electrical appliance manufacturing industry.

Most of the micro small and medium sized manufacturing enterprises have not carried out the detection of occupational hazards and evaluation of occupational hazards in accordance with the law. The situation of occupational disease prevention and control is still challenging.

Objective To evaluate the contribution of puboprostatic ligament-sparing technique in urinary continence after radical retropubic prostatectomy (RRP). Methods A total of 74 men with clinically localized prostate cancer underwent RRP. Of whom, 50 patients were performed pubo-prostatic ligament-sparing technique(group A), while 24 patients were not(group B). Patients were evaluated by independent observer questionnaire to determine their urinary continence status. Results Mean patient age [(61.3±2.4) vs (60.8±2.1)years], serum prostate-specific antigen (PSA) values [14.3±1.2)ng/ml vs (14.7±1.3) ng/ml], operative time [(110.5±10.4)min vs (109.7±10.6) mini, estimated blood loss [(250.5±23.4) ml vs (253.4±22.3) ml], and positive surgical margin rate (6% vs 8%) were not significantly different between group A and B(P>0.05). The urinary con-tinence rate with the puboprostatic ligament-sparing technique at 1-year follow-up was significantly higher than that of the control group (P<0.05). Concision The puboprostatic ligament-sparing technique significantly enhances post-operative urinary continence after RRP.

Objective To investigate the clinical and pathological features of eosinophilic diseases with cardiac involvement Methods We analyzed the clinical and cardiac pathological data of 7 patients with eosinophilic diseases with cardiac involvement under endomyocardial biopsy or autopsy.Results Seven patients (5 male, average age 51 years) were enrolled.Four patients were diagnosed as idiopathic hypereosinophilic syndrome and three were Churg-Strauss syndrome.Peripheral blood eosinophila count increased significantly in all patients.Cardiac involvement included angina pectoris, myocardial infarction, heart failure, presyncope and sudden death.Electrocardiogram showed cardiac ischemia, bundle branch block and third degree atrioventricular block.Echocardiography suggested ventricular and atrial enlargement, decreased ventricular systolic function, pulmonary hypertension, valvular prolapse and insufficiency and endocarditis.Pathology displayed infiltration of eosinophils, formation of granulomata, necrotizing vasculitis, myocardial necrosis and endomyocardial fibrosis in heart.Coronary artery could be also affected and led to myocardial infarction.Conclusions Cardiovascular complications of eocinophilic diseases are a major source of morbidity and mortality in these disorders.The manifestations are multiple and early recognition and treatment with steroid and immunosuppressant can improve prognosis.
