Objective To assess the efficacy of fish oil in the treatment of IgA nephropathy using the method of Meta-analysis. Methods Randomized controlled trials of fish oil in the treatment of IgA nephropathy were searched in the database of Cochrane library,PubMed, EMBASE and CNKI. Data extracted from the literatures were analyzed with Revman software (version 5.0). Results In comparison with the controlled group, proteinuria in the fish oil group was significantly decreased [SMD=-0.27, 95%CI (-0.52 to -0.03), P=0.03], while the renal function deteriorated [SMD=0.30,95%CI(0.05 to 0.55), P=0.02]. Conclusion Fish oil can decrease the proteinuria of IgA nephropathy, but can not prevent renal function from deterioration.

OBJECTIVETo observe therapeutic effects of locking titanium plate for the treatment of comminuted proximal humeral fracture in elderly.

METHODSFrom June 2011 to May 2013, 72 elderly patients with comminuted proximal humeral- fractures were divided into locking titanium plate group and anatomical plate group, 36 cases in each group. In locking titanium plate group, there were 16 males and 20 females aged from 60 to 79 years old with an average of (69.55±5.62) years old; 10 cases were type Neer II, 18 were type Neer III and 8 cases were type Neer IV in accordance with Neer classification; treated with locking titanium plate. In anatomical plate group, there were 15 males and 21 females aged from 60 to 81 years old with an average of (69.76±5.70) years old; 9 cases were type Neer II, 20 were type Neer III and 7 cases were type Neer IV; and treated with anatomical plate. Clinical effects, preoperative and postoperative Neer scoring, operative time, bone healing time and incidence of complications between two groups were compared.

RESULTSAll patients were followed up from 1 to 3 years with an average of 15 months. The excellent and good rate of locking titanium plate group (91.7%) was significantly higher than anatomical plate group (75.0%). Postoperative Neer score of two groups were improved obviously, but locking titanium plate group (92.51±7.85) was higher than anatomical plate group (83.64±8.56); there was no significant differences between two groups in operative time (P>0.05); bone healing time in locking titanium plate was (18.6±3.4) weeks, and shorter than anatomical plate group (24.3±3.9) weeks; incidence of complications in locking titanium plate was (5.6%) shorter than anatomical plate group (22.2%), and had obviously differences between two groups.

CONCLUSIONLocking titanium plate for the treatment of comminuted proximal humeral fracture in elderly plays an important role in good rate, bone healing time and Neer score. It has advantages of early rehabilitation exercise, less shoulder pain, rapid recovery of shoulder joint, less complications, safe and effective, and be worthy of clinical application, especially for senile osteoporosis patients.

The results of different interventions administered in 118 cases with impaired fasting glucose (IFG) for 3 years were investigated. The rates of transformation of IFG to diabetes mellitus in metformin treatment groups and rosiglitazone treatment groups were significantly lower than that in life style intervention group. This study suggested that metformin or rosiglitazone treatment could effectively reduce transformation of IFG to diabetes as compared with life style intervention.

Objective To investigate the feasibility and safety of elective synchronous laparoscopic splenectomy plus portaazygous disconnection and hepatectomy for cirrhotic portal hypertension patients with hypersplenism, esophageal and gastric variceal bleeding and hepatocellular carcinoma.Methods Two hepatocellular carcinoma patients with a history of upper gastrointestinal hemorrhage and secondary hypersplenism underwent one stage, non-emergency laparoscopic splenectomy plus portaazygous disconnection and hepatectomy between April 2015 and May 2015 in our department.Autologous red cell salvage was used during the operation.Liver resection was performed after splenectomy, portaazygous disconnection and the use of cell saver.Results The two operations were performed successfully.The operative time was 190 min and 205 min respectively, Volume of intraoperative bleeding was 180 ml and 260 ml.There was no intraoperative homologous blood transfusion.The two patients recovered smoothly, without major complications and postoperative hospital stay was 8 d and 9 d.Conclusions The procedure of synchronous laparoscopic splenectomy and azygoportal disconnection with hepatectomy for cirrhotic patients with hepatocellular carcinoma, hypersplenism and esophageal and gastric variceal bleeding is safe and feasible.

Objective To observe the effect of a novel pressure controlled water jet used in transurethral resection of bladder tumor. Methods Clinical data of 12 patients who underwent a transurethral resection of bladder tumor by using a novel water jet was retrospectively analyzed. Results All 12 cases were successfully operated. Estimated blood loss during operation was less than 5 ml. Operation time was 20-45 minutes (median was 28 min), time of water injection was 8-15 minutes (median was 12 min). There were no significant complications. All patients were followed up for 4-10 months, and tumor recurrence or progression was not found by cystoscopic examination. Conclusion Transurethral resection of bladder tumor by using a novel pressure controlled water jet is advantageous with favorable safety and feasibility.

Objective This study was aimed to discuss the safety, feasibility and availability of perimembranous ventricular septal defects(PmVSD) closure via super minimal intercostal incision under transesophageal echocardiography(TEE) guidance in children.Methods There were 81 cases of PmVSD via super minimally invasive transintercostal device closure operation(length of incision ≤ 1cm) from August 2014 to August 2016.TEE was used to guide and monitor the entire procedure.Assessed the effectiveness of device closure by postoperative regular follow-up.Results 80 patients were successfully operated by super minimally invasive transintercostal device closure in all 81 cases.Operation success rate reached 98.77%.The average diameter of ventricular septal defects was(3.72±0.96)mm.The average diameter of amplatzer occluder was(4.88±0.95)mm.Postoperative follow-up time was from 6 months to 24 months.One of 16 cases that with aneurysm of membranous septum had more than two shunts, remained a mild residual shunt beside of the amplatzer occluder but self cured during follow-up.Mild pericardial effusion was found in one patients after the operation and disappeared during follow-up.There were no cases of perioperative death, device deformation or displacement, residual shunt, complete atrioventricular block and valve involvement in the patients whom were successfully operated.One patient transferred to ventricular septal defect repair operation under direct visualization with a cardiopulmonary bypass, because ventricular fibrillation happened when guide wire passed the ventricular septal.Conclusion Super minimally invasive transintercostal device closure of PmVSD in children guided by TEE was safety and availability, that could avoid x-ray radiation and sternotomy, and operate simply, with small incision and low complication.
