[Summary] Sodium glucose cotransporter 2 (SGLT2) inhibitors have been developed as a new antidiabetic agent .The antihyperglycemic effect of SGLT 2 inhibitors is independent of insulin secretion and insulin action .SGLT2 inhibitors improve IS and islet βcell function with the possible mechanisms of reducing glucotoxicity ,weight loss and increasing GLP‐1 response .

Objective To investigate the incidence of anemia among patients with esophageal carcinoma undergoing radiotherapy, and to explore its influence on prognosis.Methods The data of 386 patients with esophageal carcinoma undergoing radiotherapy were collected retrospectively.The survival rates of the 1st, 3rd, 5th year were compared between the anemia group and non-anemia group.Analysis was carried on the impact factors of amenia on the prognosis and other clinical factors.Results The incidence of anemia before radiotherapy was 46.3 ％ (179/386), and the level of hemoglobin was 116 g/L (49-169 g/L).The incidence of anemia after radiotherapy was 74.2 ％ (286/386), and the level of hemoglobin was 98 g/L (45-152 g/L).The incidences of anemia between before and after radiotherapy were statistically different (x2 =61.915, P ＜ 0.001).The incidence of anemia before radiotherapy was associated with stage, Karnofsky score, BMI and the weight loss before treatment (P ＜ 0.05).The median survival time of the anemia group was 42 months, while that of the non-anemia group was 52 months, and the difference was statistically significant (x2 =5.002, P =0.025).There were 87.7 ％ of anemia patients got no treatment.Conclusions The prevalences of anemia before and after radiotherapy are high, and anemia before radiotherapy can decrease the survival rate in esophageal carcinoma patients.Methods should be taken to improve the haemoglobin level in order to increase the survival rate.

Objective To study severe or rare complications following radiofrequency ablation (RFA) for liver cancer. Methods Clinical records of severe or rare complications following RFA in 272 cases of liver cancer from January 2002 to December 2004 were retrospectively studied. Results A total of 301 RFA procedures were performed in the 272 cases. The incidence of severe or rare complications was 3.32% (10/301), and the death rate was 0.66% (2/301). Complications included 1 case of intraperitoneal hemorrhage, 2 cases of infection (1 case of peritonitis with sepsis and 1 case of liver Abscess superimposed upon bilioma), 3 cases of upper gastrointestinal bleeding (including 1 case of hemobilia), 1 case of hepatic arteriovenous fistula, 1 case of hemo-pneumothorax, 1 case of esophagopleural fistula and 1 case of needle-tract implantation of tumor. Conclusions In order of frequency,severe complications following RFA are upper gastrointestinal bleeding,infection and intraperitoneal hemorrhage.

Objective To evaluate the mental health of medical workers, and develop an EAP suitable for heahhcare sector. Methods A 1-year EAP was implemented in a hospital in Beijing, in which SF-36 and JSS scales were used to study the health-related quality of life and job satisfaction of these workers. Results Work pressure is found to be the main source of pressure for medical workers, accounting for 63.7%. Scores of the group receiving EAP service are found to be significantly higher (P<0.01) in all dimensions (excepting work nature and supervisor dimension) of both SF-36 and JSS. Conclusions Medical workers are exposed to high pressure of work, having strong need for EAP service as result. EAP is an effective means to maintain mental health and improve quality of life and job performance, if applied widely.

Objective To study a scoring method for assessing function status of cardiovascular system quantitatively. Methods First, exercise heart rate variability (EHRV) was obtained from the primary dynamic electrocardiogram (ECG) recorded during exercise testing. Then appropriate entropy, relative complexity, and other three parameters extracted from poincare dispersed-dot plot were extracted from the EHRV. Discriminant analysis was used to classify two extreme groups.Results Based on the values of two groups from the discriminant formula, a scoring formula was proposed and four ranks were divided according to different score domains. A novel scoring method was established. To validate the proposed scoring method, 60 middle-aged hypertensives, 50 elder subjects and 110 young healthy subjects were examined and scored. Conclusion Scores of 220 subjects are consistent with their real health status. The proposed scoring method reflects the status of the subject's cardiovascular system effectively.
