OBJECTIVETo systematically review the effectiveness of bone substitute augmentation combined with internal fixation versus internal fixation alone in treating proximal femoral fractures in the elderly.

METHODSSubject term and keywords were searched from Pubmed, Cochrane databases and CNKI from database foundation to August 2015. Randomized controlled studies and qusi-randomized controlled studies on bone substitutes augmentation combined with internal fixation versus internal fixation alone for the treatment of proximal femoral fractures in the elderly were chosen. Postoperative re-displacement, re-operation rate, complications (infection and bone ununion), functional outcome, quality of life scores and muscle strength were seen as outcome indicators. Enumeration data were statistical analyzed by risk difference and 95% confidence interval. Measurement data were analyzed by standardized mean difference and 95% confidence interval. If the same measurement data were evaluated by different standards in different studies, standardized mean differences and 95% confidence interval were used. The methods of statistical analysis were used by Cochrane databases.

RESULTSEleven RCTs (677 patients) were included. Meta-analysis results indicated that bone substitutes augmentation combined with internal fixation occurred fewer re-displacement [SMD = -0.75, 95% CI (-1.03, -0.47)] and obtained better function [SMD = 0.40, 95% CI (0.20, 0.59)]. While there were no significant differences in reoperation rate [RD = 0.02, 95% CI (-0.05, -0.09)], pain at 1 week after operation [MD = -1.79, 95% CI (-13.55, -9.96)], pain ranged from 6 to 8 weeks [MD = -7.24, 95% CI (-20.07, -5.59)], postoperative pain at 12 weeks [MD = -0.32, 95% CI (-4.9, -3.55)], muscle strength [MD = 1.25, 95% CI (-6.98, -9.48)], bone ununion [RD = 0.02, 95% CI (-0.01, -0.05)] and postoperative complications [MD = 0.01, 95% CI (-0.03, -0.04)].

CONCLUSIONCompared with single internal fixation, bone substitutes augmentation combined with internal fixation for the treatment of proximal femoral fractures in the elderly less occur re-displacement and could obtain better functional recovery.

Objective To investigate the clinical states of enuresis children companied with spina bifida occulta(SBO)and study the efficient way of treatment.Methods The children with SBO were check out by X ray from a total of 121 children with bedwetting.Their parents were asked to complete the enuresis questionnaires.Urine routine test and B-ultrasound examination about kidney,bladder and ureter were also asked to be done.The clinic data of the 49 children were attained and analyzed.They were randomly divided into 2 groups,and given the controlled treatment.Group A[used 1-deamino-8-D-arginine vas-opressin(DDAVP)only] and group B(used DDAVP plus oxybutynin plus bladder training)treated for 12 weeks.Results There were totally 49 bedwetting children companied with SBO,and most of them(44 cases,89.8%)were severe type(bedwetting times≥7 times/week).Some of them coexisted with frequency,urgency,gentle urgency incontinence and microscopic hematuria(22 cases).Thirty cases were found the functional bladder capacity(FBC)decrease by B-ultrasound.The cure rates were 58.3%(group A)and 88.0%(group B)respectively.The relapse rates were 36.8%(group A)and 12.5%(group B)respectively after stopping treatment for 3 months.Conclusions SBO accounts for considerably higher rate in enuretic children.It might cause the disability of bladder function.The treatment plan with DDAVP plus oxybutynin plus bladder training can not only increase the cure rate but also lower the relapse rate.

OBJECTIVETo evaluate the effects of Bevacizumab on the tumor growth, proliferation and apoptosis of gastric cancer xenograft, and the impacts on the VEGF and Sp1 expression.

METHODSGastric cancer xenografts in nude mice were established using SGC-7901 gastric cancer cell line. The nude mice were randomly divided into two groups, Bevacizumab treatment group and PBS group. The tumor sizes were measured for tumor growth curve. The proliferation and angiogenesis were evaluated by immunohistochemistry (IHC) staining of Ki67 and CD34. TUNEL assay was used for apoptosis evaluation. The expression of VEGF and Sp1 in tumor cells were detected by IHC and Western blot.

RESULTSCompared to the PBS group, the tumor growth decreased significantly (P<0.05), the proliferation of tumor cells and angiogenesis decreased, and apoptosis index increased significantly [(5.3 ± 1.8)% vs. (16.7 ± 6.7)%, P<0.01] in Bevacizumab group. The results of IHC and Western blot demonstrated that the expression of VEGF and the microvessel density (MVD) was decreased (4.0 ± 1.0 vs. 16.3 ± 1.5, P<0.001) in Bevacizumab treatment group. No obvious changes of Sp1 expression were observed in Bevacizumab treatment group.

CONCLUSIONSBevacizumab can inhibit the growth of gastric cancer xenografts in nude mice, decrease the VEGF expression and MVD. However, the compensatory up-regulation of transcription factor Sp1 is not affected by Bevacizumab.

OBJECTIVETo observe the therapeutic effects of beta-elemene combined DC/Dribble vaccine in treating mice with hepatic cancer, thus exploring their anti-tumor mechanisms.

METHODSDentritic cells were derived from Balb/c mice's spleen and their phenotypes were identified. Using hepatic cancer cell line BNL1MEA.7R.1 (abbreviated as BNL) originated from Balb/c mice as target cell, DC/Dribble vaccine was prepared via raising the antigen representing carrier autophagosomes (DRips in Blebs, DRibbles), which were rich in tumor antigen information. The mice previously immunized were divided into 4 groups, i.e., the control group, the beta-elemene group, the vaccine group, and the combined group. The PBS was subcutaneously and intraperitoneally injected to mice in the control group. The beta-elemene was intraperitoneally injected at the daily dose of 50 mg/kg to mice in the beta-elemene group and the combined group for 7 successive days. DC/Dribble vaccine was injected into the lymph node of mice in the vaccine group and the combined group on the 1st day, and DC/Dribble vaccine was subcutaneously injected on the 3rd day and the 5th day. All the mice were sacrificed on the 10th day. Their spleens were obtained sterilely, and the suspension was incubated with or without Dribble. The cells were inoculated for 72 h. The contents of IFN-gamma in the supernatant were measured by ELISA. In addition, the spleen cells obtained from the combined group were incubated with different stimulations for 72 h, which were then divided into the control group, the DRibble group, the DC group, and the DC/Dribble vaccine group. The supernatant of cultured cells were collected and the contents of IFN-gamma were measured by ELISA. The liver tumor-bearing mouse model was established, and then the BNL bearing mice were randomly divided into 4 groups, i.e., the control group, the beta-elemene group, the vaccine group, and the combined group. The treatment ways were the same as the immune ways. The tumor size and the survival period were observed in each group. On the 23rd day the mice were sacrificed. The tumor tissue was stripped and stained by HE staining. The pathomorphological manifestations of the tumor tissue were observed by light microscope.

RESULTSIn vitro detection of mice immunized previously by different ways showed that the secretion of IFN-gamma was significantly higher in the combined group than in the rest groups (P < 0.01). The secretion of IFN-gamma was significantly higher in the beta-elemene group and the vaccine group than in the control group (P < 0.01). The spleen cells could be stimulated to secrete a large amount of IFN-gamma in the vaccine group and the Dribble group (P < 0.01). When the beta-elemene was 10 microg/mL as the stimulating dose, the secretion of IFN-gamma obviously increased (P < 0.01). In vivo observation showed that the growth velocity of tumors in mice of the combined group was slowed down. There was statistical difference in the tumor area or the survival period of mice in the combined group, when compared with the other groups (P < 0.01). In HE staining, the surrounding connective tissues of the tumor were wrapped tightly and compactedly, with infiltration of a large amount of inflammatory cells.

CONCLUSIONSbeta-elemene combined DC/Dribble vaccine could induce specific immune cells to secrete secretory cells, thus exerting its anti-tumor effect. Its immunological effects might be associated with enhancing the DC antigen presenting function.
