Objective To investigate the effects of endogenous estrogen on blood glucose level,serum insulin level,and plasma total antioxidant capacity in streptozotocin-induced diabetic female mice,and to explore possible protective effects of estrogen on pancreatic islet cells.Methods Female mice were randomly according to body weight divided into four groups:( 1 ) Sham( Sham operation and vehicle administration) ; ( 2 ) Ovx( ovariectomy and vebicle administration ) ; ( 3 ) Sham + STZ ( Sham operation and STZ administration ) ; and ( 4 ) Ovx + STZ ( ovariectomy and STZ administration).The diabetic mice were induced by intraperitoneal injection of streptozotocin (STZ,50 mg/kg ).Blood glucose levels were measured once a week.Results The blood glucose level and malondialdehyde of Ovx group were higher than that in Sham group,while total anti-oxidant capacity ( T-AOC ) was lower than those in Sham group.the blood glucose level and MDA of Ovx+ STZ group were higher than those in Sham +STZ group,while T-AOC and serum insulin level were lower than those in Sham + STZ group.Conclusions Endogenous estrogen may have some protective effects on pancreatic islet function from streptozotocin-induced diabetes mellitus in female mice.

Objective To explore the clinical effects of solitaire AB stent assisted with coil embolization therapy in the treatment of wide-necked intracranial aneurysms. Methods A total of 30 patients with wide-necked intracranial a-neurysms who were admitted in our hospital and given the treatment of stent combined with coil embolization technique from August 2013 to August 2014 were selected. The patients were given the treatment of anti-coagulation and anti-platelet during perioperative period. Cerebral angiography was re-examined 3 months after the surgery and embolization effect was evaluated. Results 30 patients (30 pieces) with wide-necked intracranial aneurysms were treated with soli-taire AB stent assisted with coil embolization therapy in this study, among whom 26 patients were fully and closely em-bolised, 3 patients were embolised over 90%, and 1 patient was embolised mostly (85%-90%). Follow-up was carried out for patients 2-12 months. Modified Rankin scores (mRS) was applied for evaluation. 25 patients were scored 0, 4 were scored 1 and 1 was scored 2. One of the patients died after rescue due to severe cerebral angiospasm induced by subarachnoid hemorrhage followed by diffuse brain swelling. No rupture of aneurysms was seen in other patients during the embolization surgery, and no surgery-associated complications such as stent displacement and bleeding. Satisfactory effect was achieved for patients with wide-necked intracranial aneurysms receiving stent assisted with embolization surgery. All patients were followed-up by cerebral angiography, and no relapse of arterial aneurysm was detected. Conclusion Solitaire AB stent assisted with coil embolization technique in the treatment of wide-necked intracranial a-neurysms is safe and effective.

ObjectiveTo investigate the efficacy and safety of venlafaxine in the treatment of depression under the guidance of pharmacogenomics testing， and to provide references for individualized medication. MethodsA total of 66 patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for depressive episode were included in the study. Patients who were recommended to be treated with venlafaxine in the pharmacogenomics testing report were divided into study group （n=32）， and those who were decided to be treated with venlafaxine by doctors after consultation with patients were divided into control group （n=34）. At the baseline and the end of the 2^nd， 4^th， 6^th and 8^th weekend of treatment， Hamilton Depression Scale-24 item （HAMD-24） was adopted to evaluate the clinical efficacy. Meanwhile， Sheehan Disability Scale （SDS） was applied to measure the social function of patients at the baseline and the end of the 8^th weekend of treatment. After treatment， Treatment Emergent Symptom Scale （TESS） was used to assess the incidence of adverse reactions. ResultsAt the end of the 4^th， 6^th and 8^th weekend of treatment， HAMD-24 scores in the study group were all lower than those in the control group， with statistical differences （t=2.344， 4.316， 5.760， P<0.05 or 0.01）. At the end of the 8^th weekend of treatment， SDS score of the study group was lower than that of the control group， with statistical difference （t=2.173， P<0.05）. The adverse reaction rate in the study group was lower than that in the control group， with statistical difference （χ²=5.720， P<0.05）. ConclusionTreatment of depression with venlafaxine based on pharmacogenetic testing is an effective and safe way to alleviate the depression symptoms in patients.
