Objective To investigate the effects of iri doid on the spermatogenesis in mice of type-2 diabetes induced by nicotinamide and streptozotocin. Methods Fifty-six male C57BL mice were randomly divided into seven groups (n=8 for each group):control group, diabetic group, diabetic and glibenclamide (0.25 mg/kg) group, diabetic and iridoid (20 and 40 mg/kg) group, and iridoid (20 and 40 mg/kg) group. Diabetic model was induced by intraperitoneal injection of streptozotocin (65 mg/kg) and nicotinamide (120 mg/kg). Glibenclamide and iridoid were orally fed for 28 days. Twenty-four hours after the last treatment, blood samples, testis and the epididymis were collected for detecting blood hormones, testicular biopsy, and the evaluation of sperm parameters. Results The body weights of diabetic mice were recovered from the reduction after treatment with 40 mg/kg of iridoid and glibenclamide(P<0.05). The sperm count and viability were significantly decreased in diabetic group compared with those of control group (P<0.05). The sperm count was significantly increased in diabetic and glibenclamide group than that of diabetic group (P<0.05). The serum levels of lutein hormone (LH), follicle stimulating hormone (FSH) and testosterone (T) were significantly decreased in diabetic group compared with those of control group (P<0.05). The serum levels of LH, FSH and T were increased after treatment with 40 mg/kg of iridoid and glibenclamide (P<0.05). Conclusion These results suggest that iridoid can reduce the level of oxidative damage in
diabetic mice, and effectively improve the fertility of mice.

BACKGROUND:Rabbit VX2 hepatocarcinoma models are characterized by expanded and infiltrative growth, abundant blood supply, similar pathological and imaging features to human hepatocelular carcinoma, so this model is ideal for imaging experiments. OBJECTIVE: To establish rabbit VX2 hepatocarcinoma models and compare two different laparotomy methods in establishing rabbit VX2 hepatocarcinoma models. METHODS:Thirty New Zealand rabbits were randomly divided into two groups: traditional laparotomy (tumor particles were directly embedded into the liver with tweezers) and improved laparotomy (tumor particles were injected into the liver through a 15G syringe needle). The growth features of the tumor established in two different ways were compared by ultrasound. RESULTS AND CONCLUSION:The tumor formation rate was 100% in the two groups; the single rate was respectively 50% and 90%; the ectopic implantation rate was 50% and 10%, there were significant differences between two groups (P < 0.05). The mortality rate within 2 weeks was 33% and 0 in the two groups, with significant differences (P < 0.05). The improved laparotomy method is feasible for modeling rabbit VX2 hepatocarcinoma, due to minimal injury, short operation time, high success rate and stable features.

Objective To study the the effectiveness of Entecavir on serum transforming growth factor-β1 (TGF-β1) in patients with decompensated cirrhosis .Methods Eighty patients with decompensated cirrhosis were randomly divided into two groups ,the control group(n=40 cases) and the observation group (n=40 cases).The pa-tients in the control group were treated through the conventional treatmeat ,while the patients in the observation group were treated through the conventional treatment plus entecavir .They were treated for 24 weeks.Liver function,HBV DNA and serum TGF-β1 were detected.Results ALT,Tbil and ALB were improved after treatment in both groups (t=6.724,13.306,3.064,4.172,2.924,3.172,all P<0.05).They were more significantly improved in the obser-vation group than that in the control group (t=2.469,2.160,3.064,all P<0.05).HBV-DNA negative rate in the observation group was higher these in the control group (χ2 =4.82,P<0.05).Serum TGF-β1 in both groups were decreased after treatment(t=6.842,8.062,all P<0.01).There was a significant difference between two groups (t=3.178,P<0.05).Conclusion Entecavir can decrease serum TGF-β1 in patients with decompensated cirrhosis .

Recently ,metabolic surgery has received much concern for its notable and everlasting effectiveness on glucose control ,weight loss and other metabolic disorders and concomitant diseases. Previous clinical practice and guidelines mostly focused on surgical indications ,especially BM I cut‐off point. In recent years ,BMI cut‐off point in guidelines has shown a downtrend and BMI cut‐off value has tended to become obscure ,which harvested from that clinical staff have realized the importance of comprehensive control for long‐term multiple metabolism and risk factors and overall benefit of the patients through increased clinical evidences and no longer limited to the improvement of obesity and diabetes itself.

Aesthetics of science is truly present.But only those people who have ability to appreciate the beautiful can comprehend the aesthetics of science.Aesthetics of science is a senior pattern of aesthetics.Aesthetics of science can arouse people to explore knowledge and truth.Aesthetics of science bring first light of morning to medical science education which has lots of beautiful material.Recognizing aesthetics of science in medical science education is helpful to cultivating the higher quality persons with ability of medicine and training aesthetic accomplishment.

With the improvement of social living standard and the continuous promotion of patients' requirements,the integrated nursing work has already been a complicated and creative job,and brings nursing staff a huge psychological stress.A good mental character is one of the key factors that builds up and adjusts the harmonious relationship between patients and nurses,furthermore,is also a necessity for nurses to accomplish integrated nursing work.Therefore,it is hospital governors' first consideration to help nurses relive mental pressures and improve their adapting capacity.
