Objective: To investigate the risk factors of deep vein thrombosis after stroke. Methods: A retrospective analysis was made on the 420 cases patients with stroke in our hospital, according to the situation thrombosis were divided into thrombosis group and non-thrombosis group, compared two groups of patients with general information, and many factors with the significant indexes were retrospectively analyzed. Results: Age≥70 years old, bedridden, Wells score≥2 points lower limb NHSS score≥3, anticoagulant therapy, higher admission D-2 dimer, lower BI score and non-rehabilitation therapy were independent risk factor for stroke in patients with acute DVT. Age≥70 years old, bedridden, leg NHSS score≥3 points, the acute stage of DVT and BI score were the independent risk factor for stroke patients follow-up period of DVT. Conclusion:There are many related risk factors for stroke in patients with deep vein thrombosis, these factors should be used to carry out monitoring and preventing deep vein thrombosis, active rehabilitation and anticoagulant therapy should be taken to improve the prognosis of patients with stroke.

Objective:To investigate the clinical effects of transcranial ultrasound to arterial recanalization in acute ischemic stroke patients.Methods: Eighty cases of patients with acute ischemic stroke from February 2010 to May 2013 in our hospital were chosen as the experimental objects, and were divided into experimental group and control group randomly. The control group were treated with urokinase and transcranial ultrasound, the experimental group were treated with urokinase and placebo. The clinical effects of each group were compared.Results: The experimental group in the 2h and 24h when the recanalization rate was obviously higher than the control group, and the difference is statistically significant(x2=8.916,x2=8.155,P<0.05). Symptoms improved rate of patients in the 2h and 24h in the experimental group was obviously higher than that of the control group, and the difference was statistically significant. The experimental group prognostic good rate was 56.09%, while the control group was 23.08%, the difference was statistically significant(x2=9.081,P<0.05). The two groups had no statistically significant difference in mortality(x2=0.005,P<0.05). Conclusion: Patients with acute ischemic stroke with transcranial ultrasound treatment can significantly improve the prognosis of the patients condition, improve the rate of recanalization.

Objective To investigate the etiology, clinical features, diagnosis and treatment of regional portal hypertension (RPH).Methods The clinical data of 26 patients with RPH treated in Beijing Chaoyang Hospital Affiliated to Capital Medical University between January 2005 and June 2010 were analyzed with retrospective analysis.The first symptom, routine analysis of blood, liver function test, hepatitis B and C markers, tumor markers, abdominal ultrasound, abdominal enhanced CT, endoscopy findings of 26 patients and the results of abdominal CT angiography (CTA) of 16cases were analyzed.Results Pancreatic disease (18 cases) was the leading cause of RPH.The main clinical manifestations of splenomegaly in 26 cases, irregularly abdominal pain in 14 cases, and upper gastrointestinal bleeding in 10 cases.Isolated gastric varices were revealed by endoscopy in 25 cases,complicated with lower esophageal varices in 1 case.4 cases with endoscopic tissue glue injection in gastric variceal bleeding, splenectomy in 4 cases, 2 cases with splenectomy and pericardialdevascularization, 2 cases with splenectomy, pancreatic tail resection and spleno-renal shunt, 3 cases with splenic embolization treatment.Conclusions RPH often accompanied by pancreatic disease,manifested as splenomegaly, hypersplenism, but normal liver function, absence of liver cirrhosis.Isolated gastric varices is the characteristic features of RPH.RPH caused by benign diseases is curable.Splenectomy is more effective than simple endoscopic hemostasis in RPH associated with gastrointestinal bleeding.

Objective The color of the syphilis quality control material adopted by most detection institutes was the same with the detected serum sample and they were all colorless,transparent or light yellow.There were cases of wrong adding,missing adding or insufficient adding due to the color of quality control materials which was hard to distinguish with naked eyes.To avoid this phenomenon,a new method was established for the distinction of quality control materials.Methods A new method of syphilis quality control materials that had been improved three concentrations control materials:0.125,0.250 and 0.500 NCU/mL.The syphilis diagnostic kit that was created by Shanghai Kehua and Xiamen Yingke was adopted to conduct detection and compare results.Results The difference between stained quality control material and unstained quality control materials had no statistical significance (P＞0.05).Two different reagents were used to detect quality control materials of different concentration for 20 times and the CV were 11.7 ％-13.4％ and 9.3 ％-12.9 ％ respectively.Two different reagents were used to detect quality control materials of different concentration for 30 days and the CV range were 10.1 ％-13.4 ％ and 8.08 ％-12.8 ％.Conclusion Citric yellow staining does not influence the properties of syphilis control materials and it can be used stably for a long time.It is suitable for clinical lab application and promotion.

Objective To compare the control effect on postoperative GER disease between tubular EC stomach esophagus anastomosis and the traditional full stomach esophagus anastomosis.Methods From September 2010 to October 2015 in Bozhou People's Hospital,85 patients diagnosed with esophageal cancer undergoing elective resection were randomly divided into a tubular stomach EC group (45 cases) and total gastrectomy group (40 cases),two patients underwent esophageal resection,wherein the tubular stomach set of rows of tubular esophagus stomach anastomosis,total gastrectomy group underwent conventional full stomach esophagus anastomosis.After the surgery until the patient to return to normal gastrointestinal function uses dynamic monitor its pH 24h esophageal pH monitoring chamber,the other respectively after 1 March using RDQ Scale GER-related symptoms in patients with score,at the same time Statistics after 1 March of the occurrence of GER.Results There were no deaths occurred,and no occurrence of postoperative anastomotic fistula and thoracic gastric emptying dysfunction,etc;the two groups were almost reached full monitoring 24 h,and between groups while monitoring the total time,Li position monitoring time,there was no significant supine monitoring time (P＞0.05);24 h reflux episodes long tubular gastric reflux group and significantly less than the number of total gastrectomy group,the longest duration of reflux and pH value ＜4.00 The cumulative time was significantly shorter in total gastrectomy group,DeMeester scores were significantly lower than the total gastrectomy group,between groups were statistically significant (P＜0.01);postoperative gastric tube 1,March RDQ score and incidence of GER significantly lower than the total gastrectomy group,between groups were statistically significant (P＜0.01 or P＜0.05).Conclusion Tubular stomach esophagus anastomosis compared with conventional full stomach esophagus anastomosis resection of esophageal cancer has a more ideal GER disease control effect,and can provide a reference for the choice of nastomosis ways for patients with esophageal cancer surgery.

OBJECTIVETo investigate the effect of baicalein on the gap junction intercellular communication (GJIC) in the TM4 Sertoli cells of the mouse testis and its related mechanism.

METHODSWe measured the cytotoxicity of different concentrations of baicalein on the TM4 Sertoli cells in the mouse testis by MTT, detected the fluorescence transfer of the TM4 Sertoli cells by parachute assay, and determined the expression of the protein connexin 43 ( Cx43) in the baicalein-treated cells by Western blot and immunofluorescence assay.

RESULTSBaicalein produced no obvious cytotoxicity on the TM4 Sertoli cells at the concentration below 60 µmol/L but significantly increased their GJIC at 0-20 µmol/L (P < 0.01). Western blot and immunofluorescence assay showed that 0-20 µmol/L baicalein remarkably elevated the expression of Cx43 in the TM4 cells (P < 0.01) and on the membrane of the TM4 cells.

CONCLUSIONBaicalein at the concentration of 0-20 µmol/L can significantly enhance GJIC in mouse TM4 Sertoli cells by increasing the expression of the Cx43 protein.
