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.

OBJECTIVETo establish discriminant functions of diarrhea-predominant irritable bowel syndrome (IBS-D) by studying it from quantitative diagnosis angle, hoping to reduce interference of subjective factors in diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.
METHODSA Chinese medical clinical epidemiological survey was carried out in 439 IBS-D patients using Clinical Information Collection Table of IBS. Initial syndromes were obtained by cluster analysis. They were analyzed using step-by-step discrimination by taking information of four Chinese medical diagnostic methods and serum brain-gut peptides (BGP) as variables.
RESULTSClustering results were Gan stagnation Pi deficiency syndrome (GSPDS), Pi-Wei weakness syndrome (PWWS), Gan stagnation qi stasis syndrome (GSQSS), Pi-Shen yang deficiency syndrome (PSYDS), Pi-Wei damp-heat syndrome (PWDHS), cold-damp disturbing Pi syndrome (CDDPS). Of them, GSPDS was mostly often seen with effective percentage of 34. 2%, while CDDPS was the least often seen with effective percentage of 5.5%. A total of 5 discriminant functions for GSPDS, PWWS, GSQSS, PSYDS, and PWDHS were obtained by step-by-step dis- crimination method. The retrospective misjudgment rate was 4.1% (16/390), while the cross-validation misjudgment rate was 15.4% (60/390).
CONCLUSIONThe establishment of discriminant functions is of value in objectively diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.

OBJECTIVETo investigate the relationship between C-reactive protein (CRP) + 1444C/T, CRP+1059G/C polymorphisms and chronic periodontitis (CP) in a Han Chinese population.
METHODSClinical periodontal parameters [attachment loss (AL) probing depth (PD) and bleeding on probing (BOP)], and serum CRP levels were examined in CP patients (n = 126) and healthy subjects (n = 113).
RESULTSThe mean serum CRP level [(1.74 ± 1.67) mg/L] was significantly higher in the CP group than in the control group [(0.57 ± 0.39) mg/L], P < 0.001. In the control group, serum CRP levels were significantly lower in subjects with the CRP +1059 GC and CC genotypes than those with the CRP +1059 GG genotype (P < 0.01). There was no significant difference between genotypes in the CP group. In CP and the control groups, serum CRP levels were significantly higher in subjects with the CRP + 1444 CT and TT genotypes compared to those with the CRP + 1444 CC genotype (P < 0.5). The percentage of CRP + 1059 C allele was 6.7% (17/252) in the CP group and 4.9% (11/226) in the control group. The percentage of CRP + 1444 T allele was 6.3% (16/252) in the CP group and 5.3% (12/226) in the control group (P > 0.5). There was no significant difference between groups in both allele frequencies (P > 0.5). The association of CRP + 1059G/C, CRP + 1444 C/T polymorphisms with CP was not found in a regression model (P > 0.5).
CONCLUSIONSThe presence of a CRP + 1059C-allele was associated with lower serum CRP levels and the presence of a CRP + 1444T-allele was associated with higher serum CRP levels. However, the data suggested that CRP + 1059G/C, CRP + 1444 C/T polymorphisms were not significantly associated with serum CRP levels of chronic periodontitis patients in ethnic Han Chinese.
