Objective To systematically evaluate the association between protein C and Legg -Calve -Perthes disease.Methods A literature research was performed through PubMed,Embase,Cochrane library,Web of Science,Chinese Biomedical Literature Database(CBM),China National Knowledge Infrastructure(CNKI)and Wan-fang Database from inception to February 201 6 on the association between protein C and Legg -Calve -Perthes disease.According to the Newcastle -Ottawa Scale(NOS)criteria,the quality of studies was evaluated and data were extracted.Meta -analysis was performed with Stata 1 1 .0 software.Results A total of 1 4 articles were included.Twelve articles on protein C and Legg -Calve -Perthes disease in the study group and the control group were compared.The results of Meta -analysis showed that there was no significant difference in protein C levels between the study group and the control group[odds radio(OR)=1 .41 ,95% confidence interval(CI)(0.87,2.28),P =0.1 47];five articles on protein C and the white race of Legg -Calve -Perthes disease between the study group and the control group were com-pared,The results of Meta -analysis showed that there was no significant difference in protein C levels between the whiteskin patients′group and the control group[OR =0.61 2,95%CI(1 .83,7.29),P =0.61 2];three articles on pro-tein C and the yellow race of Legg -Calve -Perthes disease between the study group and the control group were com-pared,and the results of Meta -analysis showed that there was no significant difference in protein C levels between the yellow skin patients group and the control group[OR =0.59,95%CI(0.05,6.72),P =0.080].Conclusion There is no significant correlation between protein C and Legg -Calve -Perthes disease.

BACKGROUND:The repair method of proximal humeral comminuted fractures in the elderly remains controversial. OBJECTIVE:To compare the recovery of shoulder joint function using the hemiarthroplasty of shoulder and locking proximal humeral plate fixation for complex proximal humeral fracture in the elderly. METHODS:A total of 22 elderly patients with complex proximal humeral fracture, who were treated from October 2012 to October 2014, were retrospectively analyzed. 12 cases underwent hemiarthroplasty, and 10 cases received locking proximal humeral plate fixation. Al patients were folowed up after treatment. X-ray films were rechecked during the folow-up. The recovery of shoulder function was evaluated with Neer score. RESULTS AND CONCLUSION:During final folow-up, no prosthetic loosening or avascular necrosis of humeral head was found in the shoulder hemiarthroplasty group, and the Neer score was (81±5) points. In the locking proximal humeral plate fixation group, there was fixator loosening in four cases and avascular necrosis of humeral head in three cases, and the Neer score was (69±5) points (P < 0.05). During repair, mean operation time was shorter in the shoulder hemiarthroplasty group than in the locking proximal humeral plate fixation group. The amount of bleeding was higher in the shoulder hemiarthroplasty group than in the locking proximal humeral plate fixation group (P > 0.05). These data suggest that locking proximal humeral plate fixation and shoulder hemiarthroplasty are effective repair methods for complex proximal humerus fractures, but the hemiarthroplasty had the advantage of early functional exercise and good recovery of shoulder joint.

Objective To explore the change of nerve growth factors(NGF) through the blood brain barrier(BBB) after distal intravenous injection of mannitol into the experimental rats and the effect of exogenous NGF on the expression of growth associated protein-43 in hypoxic-ischemic brain.Methods One hundred cases of 7 days rats were divided into 2 units.One unit was divided into 3 groups:treatment group,control group and sham operated group,20 rats in each group.The other unit was divided into 4 groups:mannitol and NGF treated group,NGF treated group,control group,and sham operated group,there were 10 rats in each group.The model rats with perinatal hypoxic-ischemic brain damage(HIBD) rats were prepared by ligation of left common carotid artery with a temporary systemic hypoxia(inhaling 80 mL/L O2 and 920 mL/L N2).The sections of brains were processed by immunochemistry with antibodies against GAP-43,and the study and memory ability of rats were tested by maze test.The effect of osmotic opening of BBB on the facilitation of NGF′s passage was tested by ELISA.Results The expression of GAP-43 increased after NGF treatment,and the differences were remarkable(P

OBJECTIVETo investigate the diagnosis and differential diagnosis of extranodal Rosai-Dorfman disease.

METHODSTwo cases of extranodal Rosai-Dorfman disease were studied using hematoxylin-eosin, and immunohistochemical staining, along with a literature review.

RESULTSThe lesions of RDD were characterized by the presence of large histiocytes with emperipolesis, accompanied by infiltration of lymphocytes, plasma cells and other inflammatory cells. The large histiocytes had an abundant cytoplasm, pale to eosinophilic in appearance, positive for S-100 protein staining, with a vesicular nucleus and a small basophilic nucleolus in each cell.

CONCLUSIONSExtranodal Rosai-Dorfman disease is known as an idiopathic proliferative disease of histiocytes with a distinct morphologic feature and is very rare. Differential diagnosis from other types of fibrohistiocytic proliferation lesions is recommended.

OBJECTIVETo assess the therapeutic efficacy and adverse effects of endogenetic field hyperthermia (EFH) in combination with L-OHP /LV / 5-FU in the treatment of advanced gastric cancer.

METHODSThis study included 147 surgical patients with stage II-IV gastric cancer, who received postoperative chemotherapy with FOLFOX (L-OHP 85 mg /m square, 3 h intravenous infusion, followed by infusion of LV at 200 mg /m square in 2 h, intravenous injection of 5-Fu at 400 mg /m square, and intravenous infusion of 5-FU at 3000 mg /m square in 48 h). Eight treatment cycles (each lasting for 14 days) were administered. In 68 cases randomly selected from the cohort, EFH was performed on the first and third days (treatment group), but not in the other 79 cases (control group).

RESULTSThe response rate was 68.4% in the treatment group and 36.4% in the control group, showing significant difference between them (P<0.05). The 1-year survival rate was 88.2% in the treatment group, similar to the rate of 81.0% in the control group (P< 0.05), but the 3, 5-year survival rates in treatment group (67.6% and 30.9%) was significantly higher than those in the control group (47.6% and 15.4%, P<0.05). The adverse effects were similar between the two groups.

CONCLUSIONEFH combined with the chemotherapeutic regimen FOLFOX might improve the therapeutic effect of stage II-IV gastric cancer without obviously increasing the adverse effects.

OBJECTIVETo investigate the factors that affect the prognosis of primary gastrointestinal non-Hodgkin's lymphoma (PGI-NHL).

METHODSThe clinical data of 116 patients with pathologically confirmed PGI-NHL we treated from January 1993 to December 2003 were analyzed retrospectively. Kaplan-Meier survival analysis was used for analyzing the survival of the patients, and Log-rank test was performed to compare the survival rates in relation to different prognostic factors.

RESULTSThe 3-year and 5-year survival rates of the patients were 63.8% (74/116) and 48.2% (40/83), respectively. Univariate analysis revealed that the factors affecting the prognosis of the patients included the presence of B symptom, tumor size, clinical stage, pathological type, depth of invasion, and treatment methods. The patients with B symptom, tumor size no less than 10 cm, advanced clinical stage (stages III(E) and IV(E)), T-cell type, and invasion beyond the serosa who received only surgical management had poorer prognosis than those free of B symptom with tumor size <10 cm, early clinical stage (stages I(E) and II(E)), B-cell type, and submucosal or serosal invasion managed with chemotherapy alone or in combination with surgery. Multivariate analysis showed that B symptom, tumor size no less than 10 cm, advanced clinical stage (stages III(E) and IV(E)), T-cell type, invasion beyond the serosa, and surgery alone were independently associated with poor prognosis.

CONCLUSIONThe tumor size, clinical stage, pathological type, treatment methods are the independent factors affecting the prognosis of patients with PGI-NHL.
