BACKGROUND:There is controversial on which method is preferred for the treatment of humeral shaft fractures, plate or intramedul ary nail fixation? Some studies have compared the effect of those two methods, but the results are different. While the results of the systematic research and the Meta-analysis on the comparative studies is also different due to the differences in the number and the extraction of the researches.
OBJECTIVE:To systematical y evaluate the efficacy of plating versus intramedul ary nail fixation in the treatment of adult humeral shaft fracture.
METHODS:A computer-based retrieve was conducted in PubMed database, MEDLINE database, Cumulative Index to Nursing&Al ied Health Literature, Evidence-Based Medicine database, CBM database, Wanfang database and CNKI database for the randomized or quasi-randomized control ed trials on the comparison of plating and intramedul ary nail fixation in the treatment of adult humeral shaft fracture. The quality of these trials was critical y assessed according to Jadad. The effective data were extracted for Meta-analysis by Stata 12.0 software.
RESULTS AND CONCLUSION:Total y, 15 randomized or quasi-randomized control ed trials were col ected including four quasi-randomized control ed trials and 11 randomized control ed trials. The results showed that intramedul ary nail fixation may increase the risk of complications (odds ratio=0.37(0.19, 0.59), P=0.00). Bias Egger’s test of P=0.91 showed there was no significant publication bias. The risk of re-operation of intramedul ary nail fixation was increased (odds ratio=0.28(0.14, 0.57), P=0.00) with the Egger’s test of P=0.69. The incidence of shoulder impingement of intramedul ary nail fixation was significantly higher than that of pate fixation (odds ratio=0.13(0.05, 0.35), P=0.00), and there were no significant differences in postoperative infection, nonunion, implant failure, iatrogenic nerve palsy, operation time and bone union time between two methods. The results showed that compared with plate fixation, intramedul ary nail fixation may increase the incidence of shoulder impingement, complications and re-operation, while there were significant differences in postoperative infection, nonunion, implant failure, iatrogenic nerve palsy, operation time and bone union time between two methods.

OBJECTIVETo compare the efficacy of different points combination in the treatment of menopausal insomnia.

METHODSNinety-six cases of menopausal insomnia were randomized into 3 groups, Xinshu (BL 15), Shenshu (BL 23), Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6) were chosen in the restore interaction between the heart and the kidney group (group A, 32 cases); Zhaohai (KI 6), Jiaoxin (KI 8), Shenmai (BL 62), Pucan (BL 61) were chosen in the acupuncturing qiao mai group (group B, 32 cases); auricular Shenmen (TF4) and sensitive spot at the distribution area of auricular vagus nervus were chosen in the ear acupuncture group (group C, 32 cases). Six days made one session and the treatments were finished after 4 courses. The polysomnography (PSG) and Pittsburgh sleep quality index (PSQI) were employed before and after treatment to evaluate the alleviation of insomnia.

RESULTSThe parameters of the sleep latency (SL), rapid wave sleep latency (RL) and sleep efficiency (SE) were significantly improved in the three groups, and the differences were statistically significant (P < 0.05, P < 0.01). The SL and awaking time (AT) in group C [SL (401.08 +/- 16.54) min and AT (4.87 +/- 2.64) times] were significantly superior to those in the other two groups [SL (50.36 +/- 18.47) min, (54.87 +/- 20.92) min, AT (5.98 +/- 2.11) times, (6.13 +/- 3.04) times, all P < 0.05]. The S(3+4) (%) in group C was also significantly higher than those in the other two groups (both P < 0.05). It was indicated by PSQI that the sleep quality of group C (0.78 +/- 0.12) was significantly superior to that in group B (1.32 +/- 0.29), the total score and cured and markedly effective rate in group C [(4.34 +/- 1.43), 68.8% (22/32)] were superior to those in group A [(7.48 +/- 3.09), 53.1% (17/32), both P < 0.05].

CONCLUSIONEar acupuncture has a better curative effect than the restore interaction between the heart and the kidney group and acupuncturing qiao mai group, it is worth of being promoted.

BACKGROUNDPatients with severe full-thickness burn injury suffer from their inability to maintain body temperature through perspiration because the complete destructed sweat glands can not be regenerated. Bone marrow-derived mesenchymal stem cells (BM-MSCs) represent an ideal stem-cell source for cell therapy because of their easy purification and multipotency. In this study, we attempted to induce human BM-MSCs to differentiate into sweat gland cells for sweat gland regeneration through ectodysplasin (EDA) gene transfection.

METHODSThe dynamic expression of EDA and EDA receptor (EDAR) were firstly observed in the sweat gland formation during embryological development. After transfection with EDA expression vector, human BM-MSCs were transplanted into the injured areas of burn animal models. The regeneration of sweat glands was identified by perspiration test and immunohistochemical analysis.

RESULTSEndogenous expression of EDA and EDAR correlated with sweat gland development in human fetal skin. After EDA transfection, BM-MSC acquired a sweat-gland-cell phenotype, evidenced by their expression of sweat gland markers by flow cytometry analysis. Immunohistochemical staining revealed a markedly contribution of EDA-transfected BM-MSCs to the regeneration of sweat glands in the scalded paws. Positive rate for perspiration test for the paws treated with EDA-transfected BM-MSCs was significantly higher than those treated with BM-MSCs or EDA expression vector (P < 0.05).

CONCLUSIONSOur results confirmed the important role of EDA in the development of sweat gland. BM-MSCs transfected with EDA significantly improved the sweat-gland regeneration. This study suggests the potential application of EDA-modified MSCs for the repair and regeneration of injured skin and its appendages.

OBJECTIVETo investigate the effect of curcumin (Cur) on radiosensitivity of nasopharyngeal carcinoma cell CNE-2 and its mechanism.

METHODThe effect of curcumin on radiosensitivity was determined by the clone formation assay. The cell survival curve was fitted by Graph prism 6. 0. The changes in cell cycle were analyzed by flow cytometry (FCM). The differential expression of long non-coding RNA was detected by gene chip technology. Part of differentially expressed genes was verified by Real-time PCR.

RESULTAfter 10 micro mol L-1 Cur had worked for 24 h, its sensitization enhancement ratio was 1. 03, indicating that low concentration of curcumin could increase the radiosensitivity of nasopharyngeal carcinoma cells; FCM displayed a significant increase of G2 phase cells and significant decrease of S phase cells in the Cur combined radiation group. In the Cur group, the GUCY2GP, H2BFXP, LINC00623 IncRNA were significantly up-regulated and ZRANB2-AS2 LOC100506835, FLJ36000 IncRNA were significantly down-regulated.

CONCLUSIONCur has radiosensitizing effect on human nasopharyngeal carcinoma CNE-2 cells. Its mechanism may be related to the changes in the cell cycle distribution and the expression of long non-coding IncRNA.

OBJECTIVETo isolate and identify Streptococcus mutans (Sm) and Streptococcus sobrinus (Ss) in dental plaque of children with high dmft and no caries by selective medium, biochemical methods and arbitrarily primed-polymerase chain reaction (AP-PCR).

METHODSA total of 401 3-4-year-old children from seven kindergartens were recruited using cluster sampling and their dental caries status were examined. From 30% of children with the highest dmft score (dmft >/= 5), 20 children were chosen randomly as test group and 20 age and gender-matched caries-free children were selected as control. Plaque samples were collected from buccal surfaces of the molars and plated onto TYCSB plate. Sm and Ss were primarily identified by colony morphology and biochemical characteristics. Then chromosomal DNA of the strains was isolated and Sm or Ss were confirmed by AP-PCR.

RESULTSThe proportion positive for Sm and Ss in children with high dmft was 100% and 40% respectively while that in caries-free children was 75% and 5% by AP-PCR analysis. The differences were statistically significant between the two groups.

CONCLUSIONSThe proportions positive for Sm and Ss detected by AP-PCR method were significantly higher in children with high dmft than in caries-free children and it is a risk factor for high dmft in deciduous teeth harboring Sm and Ss.

OBJECTIVETo evaluate the impact of different proton pump inhibitors on the antiplatelet activity of clopidogrel.

METHODSA total of 60 hospitalized patients undergoing percutaneous coronary intervention were randomly assigned to receive omeprazole group 40 mg/d (20 patients), pantoprazole group 40 mg/d (20 patients) and control group (20 patients). All patients also received standard clopidogrel therapy, continuing 30 days treatments. The percentage clotting inhibition was measured by the use of thrombelastogram and the maximal platelet aggregation rate (MPAR) was measured by turbidity method at the first day before admission and 15 or 30 days after treatment. Major adverse cardiac and cerebral events (MACCE) and hemorrhagic events within 30 days were recorded.

RESULTSThe baseline clinical characteristics, angiography and PCI result were compared among the three groups. At the first day before admission and 15 or 30 days after treatment, no significant difference was shown in the percentage clotting inhibition measured by thrombelastogram and the maximal platelet aggregation rate (MPAR) measured by turbidity method among the three groups. Though the platelet agglutination inhibition rate measured at 15 and 30 days increased and MPAR measured at 15 and 30 days declined compared with the baseline data (P < 0.05), no significant difference was found between levels measured at 15 and 30 days (P > 0.05). The rates of MACCE had no significant difference among the three groups. Compared with control group, the rates of hemorrhagic event were significantly decreased in omeprazole or pantoprazole group (P < 0.05), but no significant difference was shown between the omeprazole and pantoprazole group.

CONCLUSIONNo significant impact of different proton pump inhibitors on the antiplatelet activity of clopidogrel has been found in patients undergoing coronary stent implantation and short-time combined administration is safe.
