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.

Background and purpose: Lysine specific demethylase 1(LSD1) is an important chromatin modifier. It epigenetically regulates gene expression pattern through chromatin modification and participates in maintenance of tumor malignant properties, such as oncogenesis, development, invasion, migration and metabolic transformation. SIRT3 (sirtuin 3) is a mitochondria localized tumor suppressor and regulates tumor metabolic transformation and oxidative stress. The correlation between LSD1 and SIRT3 has never been reported before. This study aimed to elucidate the correlation between LSD1 and SIRT3 with gene transcriptional regulation methods. Methods: RNA interference technique, co-immunoprecipitation assay(CoIP), chromatin immune-precipitation assay(ChIP) and ifrelfy luciferase activity assay were employed to elucidate the correlation between LSD1 and SIRT3 in pancreatic cancer. Results:mRNA and protein levels of SIRT3 were signiifcantly elevated in LSD1 knock-down PANC-1 cells. LSD1 interacts with PGC-1α, an important regulator of SIRT3 gene expression. LSD1 and PGC-1αoccupied the same region in SIRT3 promoter region through ChIP analysis. Luciferase activity assay validated LSD1 as a negative regulator of PGC-1αin SIRT3 gene transcriptional regulation. Conclusion:LSD1, as an important tumor promoter, negatively regulates the expression of tumor suppressor gene SIRT3, these results provide important clues for the role that LSD1 plays in aberrant metabolism and oxidative stress.

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.
