OBJECTIVETo systematically review the effectiveness of minimally invasive total hip arthroplasty (MIS-THA) versus traditional total hip arthroplasty (THA) in patients with hip diseases.

METHODSThrough a method of combining Free words and keywords,we searched databases including PubMed,The Cochrane Library, EMbase,Web of Science, CBM , CNKI and Wanfang Data for randomized controlled trials (RCTs) on the comparison between MIS-THA and THA for hip disease from inception to June, 2014. Two reviewers independently screened literatures according to the inclusion and exclusion criteria, extracted data and assessed the quality of the included studies according to the "bias risk assessment" tool recommended by Cochrane Handbook 5.0 for Systematic Reviews. Then, meta-analysis was performed using RevMan 5.3 software.

RESULTSThirteen RCTs involving 1 213 cases of surgeries and total 1 284 hips (MIS-THA: n = 631; THA: n = 653) were identified. The results of meta-analysis showed that statistically significant differences were found in Harris hip score on the 3rd month after operation [MD = 8.37, 95% CI (6.02,10.72)], Hematocrit [MD = 0.02, 95% CI (0.01, 0.03)] and Hemoglobin [MD = 0.50, 95% CI (0.16, 0.85)] at the 48th hour after operation, changed value of femoral offset [MD = 0.30, 95% CI (0.04, 0.56)] between two groups. In the change value of femoral offset, THA was better than MIS-THA; There were no statistically significant differences between two groups in Harris hip score at 1st year after operation [MD = 3.26, 95% CI (-3.25, 9.76)], WOMAC score [MD = -0.53, 95% CI (-3.67, 2.60)] and Oxford score [MD = 1.34, 95% CI (-3.46, 6.13)] at the 6th week after operation, Hematocrit at the 8th hour after operation [MD = -0.01, 95% CI (-0.02, 0.00)], the incidence of hip varus [RR = 0.82, 95% CI (0.45,1.52)] and dislocation [RR = 1.40, 95% CI (0.48, 4.12)].

CONCLUSIONTHA brings less trauma, less hemorrhage and better early clinical outcome compared with MIS-THA, but the difference of the complication rates between the two groups is similar.

OBJECTIVETo evaluate the clinical efficacy and safety of bushen quhan zhiwang decoction (BQZD) combined methotrexate (MTX) in treating rheumatoid arthritis (RA).

METHODSA prospective, randomized controlled study was carried out. RA patients of Shen deficiency and cold invading syndrome in the treatment group (120 cases) were treated with BQZD and MTX (10 mg/week), while those in the control group (120 cases) were treated with MTX (10 mg/week) alone. The therapeutic course for all was 24 weeks. The efficacy and safety indices were evaluated at the baseline and 24 weeks after treatment, including clinical signs and symptoms, condition assessment, Health Assessment Questionnaire (HAQ), disease activity index 28 (DAS28), laboratory parameters of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), safety indicators, and Chinese medical syndrome integrals.

RESULTSThe total effective rate was 80. 0% in the treatment group, better than that of the control group (66.7%), showing statistical difference (P <0.01). In the two groups significant improvement of clinical signs and symptoms, ESR, CRP, visual analogue scale (VAS) by both physicians and patients, HAQ, DAS28, and Chinese medical syndrome integrals after treatment were shown (P <0.01). Better effects were obtained in the treatment group in lessening tender joint numbers and swollen joint numbers, VAS by both physicians and patients, DAS28, and Chinese medical syndrome integrals (P < 0.05). Besides, adverse reactions occurred less in the treatment group than in the control group (P < 0.05).

CONCLUSIONSBQZD had roles in relieving symptoms, improving joint functions, signs, ESR, and CRP. It was an effective herb for RA patients of Shen deficiency and cold invading syndrome. It could enhance the efficacy and reduce adverse reactions of MTX through synergistic effects with MTX.

OBJECTIVETo generate a gene delivery plasmid carrying the dominant negative form of the protein phosphatase 2A catalytic subunit a (DN-PP2Aca) driven by a hepatocellular carcinoma (HCC) tissue-specific promoter and investigate its ability to inhibit growth of cultured hepatoma cells.

METHODSThe gene delivery plasmid was constructed by PCR-amplifying DN-PP2Aca from wild-type PP2Aca using site-directed mutagenesis and then ligating the sequence-verified amplicon downstream of an alpha-fetoprotein enhancer and phosphoglycerate kinase promoter (AFpg) in the luciferase reporter vector pGL3-Basic. Following transfection into two AFP+ hepatoma cell lines (HepG2 and HepG3) and two AFP- hepatoma cell lines (SK-HEP-1 and L02), the transcriptional activity of the AFpg-driven DN-PP2Aca plasmid was tested using luciferase reporter gene assay and western blotting. The effect on cell growth was tested using MTT assay. Between group differences were assessed by t-test.

RESULTSThe AFpg-driven DN-PP2Aca plasmid showed high transcriptional activity and protein expression in both HepG2 and Hep3B cells. At 72 h after transfection, the proliferation capacities were repressed by 42.65%+/-3.99% (P = 0.0002) and 39.87%+/-3.91% (P = 0.0002) in AFP+ HepG2 and Hep3B cells, respectively (vs. untransfected). In contrast, the plasmid was transcriptionally inactive in and had no effect on proliferation of AFP- cells.

CONCLUSIONThe AFpg-driven DN-PP2Aca plasmid exhibits selective cytotoxicity against AFP+ hepatoma cells, and may represent a useful gene therapy strategy to treat HCC.

A qualitative analytical method of liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (HPLC-Q-TOF-MS) was developed for identification of multi-constituents and an analytical method was developed for simultaneously determining 4 major compounds (rutin, isoquercitrin, kaempferol-3-0-rutinoside, and astragalin) in Tetrastigma hemsleyanum Diels et Gilg. The HPLC-Q-TOF-MS assay was performed on a Welch Ultimate XB-C18 column (4.6 mm x 150 mm, 5 microm) with the mobile phase consisting of acetonitrile (A) and water containing 0.1% Formic acid (B) in gradient mode at a flow rate of 0.8 mL x min(-1). The column temperature was at 30 degrees C, and negative ion mode was used for TOF-MS. The UPLC-QqQ-MS assay was performed on a Waters CORTECS C18 (2.1 mm x 100 mm, 1.6 microm) with the mobile phase consisting of acetonitrile (A) and water containing 0.1% formic acid (B) in gradient mode at a flow rate of 0.25 mL x min(-1). The column temperature was at 45 degrees C, and MRM mode was used for QqQ-MS. Based on the retention time and MS spectra, 24 compounds were identified or tentatively characterized by comparing with reference substances or literatures. For quantitative the linear range of 4 detected compounds were good (r > 0.9966), and the overall recoveries ranged from 98.27% to 101.58%, with the RSD ranging from 3.15% to 5.88%. The results indicated that new approach conbined HPLC-Q-TOF-MS and UPLC-QqQ-MS was applicable in qualitative and quantitative quality control of Tetrastigma hemsleyanum.

Objective To establish the activation of NF-κB in middle ear cholesteatoma, discuss the relationship of NF-κB and the gene expression of IL-6 and explore the pathogenesis of middle ear cholesteatoma. Methods Ten cases of cholesteatoma and 6 cases of normal external meatal skin were obtained from middle ear surgery. The NF-κB DNA binding activity and the mRNA level of IL-6 in these two kinds of tissues were detected by electrophoretic motility shift assay (EMSA) and Reverse transcription polymerase chain reaction(RT-PCR) respectively. The relationship of NF-κB DNA binding activity and the mRNA level of IL-6 were analyzed. Results The NF-κB DNA binding activities of cholesteatoma [(15.9±8.2) %] were higher than those in normal skin [(1.36 ± 0.94) %, t = 3.502, P < 0.05]. The expression of IL-6 mRNA was increased significantly in patients with cholesteatoma, as compared with that in the control specimens (t = 2.166 ,P < 0.05) and had a significant positive correlation with NF-κB DNA binding activity (r = 0.752, P < 0.05). Conclusions The II.,-6 mRNA expression in cholesteatoma is closely related with the activity of NF-κB. It is tempting to speculate that NF-κB play a key role in the activation of cytokine in cholesteatoma.
