Diabetic mellitus induced erectile dysfunction (DIED) is a common complication of type 2 diabetes mellitus (T2DM), which seriously affects the physical and mental health of male T2DM patients. The occurrence of DIED involves a variety of pathophysiological changes such as vascular tissue, nerve, endocrine and so on. But the traditional treatment of erectile dysfunction is not ideal for DIED. Glucagon like peptide (GLP)- 1 receptor agonist has been widely used as a new drug for the treatment of diabetes, and the representative drugs are exenatide and liraglutide. Existing research shows that it can improve endothelial cell function, neuropathy and sex hormone secretion, reduce body weight and insulin resistance. Therefore, these drugs may be a new choice for patients with DIED.

Objective To assess the effect and influencing factors on 131I treatment for cervical lymph node metastasis (LNM) after operation in patients with PTC.Methods PTC patients (n =117;45 males,72 females;average age (45.17± 15.50) years) with postoperative cervical LNM from January 2010 to December 2014 were analyzed retrospectively.LNM was diagnosed by surgical pathology,imaging results and clinical follow-up.Single factor analysis was performed in age,gender,operation mode,TNM stage,131I treatment time and other factors.The results for 131I treatment effect included CR,PR,NC.Two-sample t test and x2 test were used.Results Among the 117 PTC patients with postoperative LNM,53 (45.3%) cases had non-131 I-avid metastasis.Fifty of the 64 (54.7%) patients with 131I-avid metastasis were treated with 131I.Nineteen patients (38.0%) achieved CR,22 (44.0%) achieved PR,and 9 (18.0%) showed invalid results.Fourteen of the 64 patients underwent another cervical lymph node dissection.Nine patients achieved CR,5 patients achieved PR,and 4 PR patients were then treated with 131I and finally achieved CR.Single factor analysis showed that the influencing factors of non-131I-avid lymph node included patients' age (t =3.459),serum Tg level (x2 =6.698) and metastasis with 1s F-FDG uptake (x2 =26.928;all P<0.05).The influencing factors of 131I treatment effect included lymph node dissection procedure (x2 =6.487),unilateral or bilateral lesion (x2=5.187) and LNM size (x2=8.099;all P<0.05).Conclusions 131I treatment is ineffective for nearly 50% of patients with non-131I-avid LNM.The influencing factors of 131I treatment effect include the lymph node dissection procedure,unilateral or bilateral lesions and LNM size.

Objective To evaluate the effectiveness of mouth gag which can inserted into lavage tube during gastric lavage. Methods The Sixty- six cases of acute poisoning patients with gastric lavage according to random number table method were randomly divided into two groups, 33 cases in each group. Observation group used the inserted mouth gag, and the control group used the metal ones. Results The observation group were lower than the control group at the time required to insert the lavage tube [(2.23±0.19)s to (3.26±0.30)s] and the incidence of complication rate [18.2%(6/33) to 45.5%(15/33)], the oral cavity bleeding [6.0%(2/33) to 30.3%(10/33)], lavage tube displacement [0(0/33)to 24.2%(8/33)], lavage tube twisting[0(0/33) to 24.2%(8/33)], the difference was statistically significant (P<0.01), while higher in the rate of successful intubation[100.0%(33/33)] to [54.5%(18/33)], the difference was statistically significant, χ2=19.4,P<0.01. Conclusions The application of the mouth gag which can insert into gastric lavage improved the successful intubation rate, saved the rescue time, reduced the complication and improved the nursing quality.

In this study, the rat type 2 diabetes mellitus (T2DM) model was established through tail vein injection with low dose of streptozotocin (STZ) and high fat diet for 8 weeks, and then treated with Jiaotai Pill. The oral glucose tolerance test (OGTT), fasting serum insulin (FINS), free fatty acid(FFA) levels and blood lipid were assayed. HOMA-IR was calculated. Pancreatic pathology was performed. And pancreatic triglyceride (TG) content was examined by the lipid extraction method. Pancreatic islet cell apoptosis were detected by terminal dexynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL). According to the results, the model group showed abnormal OGTT, increased FINS, HOMA-IR, FFA, lipid disorder, obvious fat accumulation and significantly increased TG content in pancreatic tissues, and enhanced pancreatic islet cell apoptosis. Compared with the model group, the Jiaotai Pill group displayed improved OGTT, reduced FINS, HOMA-IR, FFA, recovered lipid disorder, decreased fat accumulation and significantly declined TG content in pancreatic tissues, and lowered pancreatic islet cell apoptosis. In summary, Jiaotai pill could effectively treat type 2 diabetes in rats. Its mechanism may be related to the reduction in pancreatic fat accumulation and islet cell apoptosis.

OBJECTIVETo investigate the effect of salidroside on hypoxia-induced apoptosis of corpus cavernosum smooth muscle cells (CCSMCs) in rats.
METHODSRat CCSMCs were cultured in vitro by the enzyme digestion method and identified by immunofluorescent staining of anti-alpha-SMA and anti-Desmin. The non-toxic dose of salidroside was determined by MTT assay. Low-oxygen mixed gas (1% O2, 5% CO2, and 94% N2) was piped into a modular incubator chamber to induce hypoxia. The CCSMCs were divided into a normal, a hypoxia, and a 32 microg/mL salidroside intervention group. The apoptosis of the CCSMCs was detected by flow cytometry and the expression of the caspase-3 protein determined by Western blot.
RESULTSThe majority of the CCSMCs were positive for alpha-SMA and Desmin at immunofluorescent staining. Salidroside at < 32 microg/ml produced no obvious toxicity to CCSMCs. Compared with the normal control group, the rates of early and late apoptosis of CCSMCs were both increased significantly in the hypoxia group ([12.77 +/-1.41]% vs [18.69 +/- 1.29]%, P < 0.01 and [14.63 +/- 2.00]% vs [21.03 +/- 1.530]% , P < 0.05). Western blot showed a markedly increased expression of cleaved caspase-3 (P < 0.01). Intervention with 32 microg/ml salidroside significantly reduced hypoxia-induced early apoptosis of CCSMCs ([13.46% +/- 1.87]%, P < 0.01) and decreased the expression of cleaved caspase-3 (P < 0.01).
CONCLUSIONSalidroside can reduce the expression of cleaved caspase-3 and inhibit hypoxia-induced apoptosis of CCSMCs in rats.

Background Retinopathy of prematurity is mainly due to retinal neovascularization.Objective This laboratory work was to evaluate the efficacy of different dosage of avastin for inhibiting retinal neovascularization.Methods Ninety 7-day-old clean C57BL/J6 mice were randomized into six groups as follows:air control group,hyperxia control group,hyperxia BSS group and avastin groups.C57BL/J6 mice in air control group were raised in regular air environments.The fifty mice were fed under the environment with 75% ±2% oxygen for 5 days to establish the retinal neovascularization models.The 1.25,2.50 and 5.00 g/L avastin (0.5 μl) were injected inteavtreally in forty-five mice models as low,moderate and high dosage avastin groups respectively,and 0.5 μl BSS was used at the same way in fifteen models as hyperxia BSS group.The mice were sacrificed in the 17-day-old age using excessive anesthesia method and the retina sections were prepared for the calculation of the numbers of vascular endothelial cell nuclei broken retinal inner membrane after hemotoxylin and eosin staining.The expression of CD34 in the retina was detected by immunochemistry.The morphology and distribution of retinal neovascular vessel in various groups were observed using retinal flat.The use of the animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The numbers of cell nuclei broken the inner limiting membrane was significant increased in the hyperxia group compared with the air control group( P<0.01 ),and those in difference doses of avastin were considerably reduced in comparison with hyperxia BSS group (P<0.01) and hyperxia group (P<0.01 ).The decrease of numbers of cell nuclei broken the inner limiting membrane was obvious in low dose of high dose of avastin compared with low dose of avastin (P<0.05 ).CD34 was positively expressed in retina internal membrane of hyperxia group.Retinal flat revealed the regular distribution and normal structure of retinal vessels in air control group and avastin groups.However,retinal and vitreous cavity neovascularization,leakage and enlarged non-perfusion regions in the perimeter of the retina were seen in hyperxia group and hyperxia BSS group. Conclusions Intravitreal injection of avastin can arrest retinal angiogenesis in oxygen-induced retinal neovascularization models in a dose-dependent manner.
