Objective To explore the expression and significance of Rac1 and WAVE2 protein in glomerulus of high-
fat diet induced C57BL/6J model mice. Methods Thirty-two male C57BL/6J mice (3-week old) were randomly assigned into two groups(16 in each group). The control group was fed with basic diet (10%fat) for 4 weeks. The high-fat diet group was fed with high-fat diet (60%fat) for 4 weeks. The kidney morphological changes were examined by HE and PAS staining. The expressions of Rac1 and WAVE2 protein were examined by Western blot and immunohistochemistry analysis. Results HE and PAS results showed that there were glomeruli mesangial matrix hyperplasia and exudation in high-fat diet group compared with control group. The immunohistochemistry and Western blotting results showed that expressions of Rac 1 and WAVE2 in glomerulus were both increased in high-fat diet group compared with those of control group. Conclusion Rac1 and WAVE2 protein may be involved in glomerular injuries induced by high-fat diet.

Objective To explore the changes of plasma somatostatin(SST) in children with septic shock.Methods The level of plasma SST in children with septic shock (test group,n=21) on an empty stomach at shock stage,blood pressure and heart rate recovery stage,recovery stage(at that time clinical symptoms and signs disappeared,infection indicators such as blood routine and CRP returned to normal,about 6-12 days after admission) were detected by competive radioimmunassay,the level of SST in healthy children(healthy control group,n=25) on an empty stomach on morning was detected,too.The levels of plasma SST between septic shock concbined with paralytic ileus group and without paralytic ileus group were compared.Results 1.Level of plasma SST of test group at shock stage[(44.60?16.83) ng/L]was significantly lower than that of control group[(123.15?6.57) ng/L](t=-12.16 P0.05).The level of plasma SST of children with paralytic ileus [(28.10?7.0) ng/L] was significantly lower than that of children without paralytic ileus [(56.98?9.44) ng/L](t=-7.70 P

Objective To analyse the efficacy of methotrexate combined with mifepristone in treatment of 130 cases heterotopic pregnancy. Methods 130 cases heterotopic pregnancy from January 2014 to December 2014 in obstetrics and gynecology department of First Affiliated Hospital of Liaoning Medical University were divided into observation group and control group, randomly, 65 cases in each group.Patients in control group were treated with 1 mg/kg methotrexate of intramuscular injection, one time per day; patients in observation group were treated with mifepristone of oral, one time per day, 75mg per time on the basis of control group.The serum β-subunit of human chorionic gonadotropin (β-hCG), normal pregnancy rate, size of enclosed mass, rate of treatment success and adverse reactions in two groups were compared.Results The recovery time of serum β-HCG in observation group was shorter than that in control group ( P <0.05 ) , and normal pregnancy rate in observation group was higher than that in control group (P<0.05).After 7 and 14 days’ treatment, size of enclosed mass in observation group was smaller than that in control group (P<0.05).After two months’ treatment, the efficacy in observation group was higher than that in control group (92.31%vs.61.54%;χ2 =17.33,P<0.05).There was no significant difference in adverse reactions rate between two groups (χ2 =0.34,P>0.05).Conclusion Methotrexate combined with mifepristone could improve the clinical efficacy which is a safe therapy with few adverse reactions.

ObjectiveTo investigate the feasibility and superiority of video-assisted minithoracotomy surgery (VAMT) in treatment of adolescent patients with primary spontaneous pneumothorax. MethodsThe clinical data of 103 adolescent patients with spontaneous pneumothorax were analyzed retrospectively. VAMTS was performed in 56 cases and video-assisted thoracoseopic surgery(VATS) was performed in 47 cases. complications Statistical analysis were undergoing in middle-operation, post-operation and ambi-operation in the two groups were analyzed. ResultsNo statistically significant difference were found in blood loss ,operating time,pain grade, out-of-bed activity time, antibiotics use time,chest drainage time,hospital day pulmonary infection between the two groups( all P ＞0.05 ). The cost of hospitalization was lower in VAMTS group compare to VATS group ( P ＜ 0.05). ConclusionVAMT in treatment of adolescent patients with primary spontaneous pneumothorax had the advantage of simple performance, reliable effectiveness, practical,lower cost of hospitalization fee.

Objective To evaluate the value of minimally invasive technique in treatment of severe traumatic intracranial hematoma at emergency department.Method From January 1995 to December 2005,126 patients were treated by using the minimally invasive technique in Affiliated Chaoyang hospital once patients were diagnosedas severe traumatic cerebral hernia resulted from intracranial hematoma and also those whose clinical data were retrospectively analyzed.In the emergency department,the per-operative plan was done according to the CT imaging,including the sute of burr hole on the skull,the direction and depth of carmulation,and the drainage cannula was put into the hematoma cavity for external drainage under local anesthesia.Results The successful rate of puncture was 100%.The patients's dukated oyouk contracted immediately after drainage.There are 79/ 95 patients(83.1%)had single pupil dilated and 17/31(54.8%)patients had bilateral pupils dilated.The immediately clinical effective was 76.2%.According to Glasgow outcome scale,43 of 126 patients had good recovery,26 had moderate deficits and 18 had severe sequelae,16 patients were in vegetative state,18 died. Conclusions Clinical prospective study proves that minimally invasive technique can ameliorate the cerebral hernia,prolong the operative therapie window time.

This study aims to explore the impact on patient's liver and kidney function by different dosage of Kudiezi injection. This study retrospectively analyzed 15 228 patients' records from 18 nationwide general hospital information system (HIS). All patients were treated with Kudiezi injection, 1 956 patients that were given doses of > 40 mL, which is above the recommended dose, acted as the observation group. Fifty-five patients receiving the recommended dose of < 40 mL were the control group. Data about alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (Cr) and blood urea nitrogen (BUN) were collected before and after using Kudiezi injection, changes after treatment were outcomes. Also recorded were: age, costs, length of hospitalization and the patients' condition on admission. Propensity score method was used to balance 71 confounding variables such as gender, age, mortality, and costs. There were no significant difference on the four indexes between the two groups. It is hard to conclude that the use of Kudiezi injection over the recommended dose could influence the four indexes of liver and kidney from this data analysis. More conclusive evidence should be collected by further prospective study.
