Objective To evaluate the efficacy and safety of Jinkui Shenqi Pills on hypertension through Meta-analysis and systematic review. Methods Articles about intervention of modified Jinkui Shenqi Pills in hypertensive clinical randomized controlled trials were retrieved from CNKI, Wanfang database, VIP, Cochrane Library, PubMed, and Embase. They were all searched from inception to June 2016. Cochrane system evaluation manual bias risk assessment method was used to evaluate the quality of the articles, and RevMan5.3 software was used for Meta-analysis. Results Nine articles involving 776 cases were included in the study. Meta-analysis showed that the total effective rate of modified Jinkui Shenqi Pills was better than that of conventional Western medicine treatment [OR=2.67, 95%CI (1.73, 4.11), P<0.000 01], and combination therapy was superior to conventional Western medicine alone [OR=3.27, 95%CI (1.99, 5.39), P<0.000 01]. However, the efficacy of modified Jinkui Shenqi Pills alone was equivalent to the conventional Western medicine alone [OR=1.16, 95%CI (0.43, 3.09), P=0.77). Conclusion Modified Jinkui Shenqi Pills can improve the clinical symptoms of the patients with hypertension, and combination treatment can improve the antihypertensive effect. However, the quality of the included research literature is too low, yet more large-scale, multi-center, high-quality clinical randomized controlled trials are needed to further verify.

Objective To study the neuroprotective effect of fucoidan against 6-OHDA-induced damage on MN9D cell line and preliminarily explore its mechanism.Methods The MN9D cells were treated with different concentrations of 6-OHDA(12.5,25,50,100 and 200 μmol/L)for 24 h and with 50 μmol/L 6-OHDA for different time courses(6,12,24 and 48 h)as well.Based on the above experiment,the best concentration(50 μmol/L)of 6-OHDA and time course(24 h)were selected and the damaged model of MN9D cell line was induced accordingly.The MN9D cells were pretreated with 0.01,0.1 and 1.0 mg/mL fucoidan for 1 h,and then co-treated with 50 μmol/L 6-OHDA for 24 h.The viability of MN9D cells was detected by MTT assay;the LDH leakage was detected by bioassay;the level of intracellular xidative stress was observed by 2',7'-dichlorodihydrofluorescein diacetate assay.Results MTT metabolic value decreased following the increase of 6-OHDA concentration or the extension of processing time.Treatment with 50 μmol/L 6-OHDA for 24 h induced a significant decrease of MTT metabolic rate and an increase of LDH leakage rate in the MN9D cells.Pretreatment with 0.1 and 1.0 mg/mL fucoidan inhibited the death of 6-OHDA-induced cells,increased the MTT metabolic value and decreased the LDH leakage.Cell morphological changes were consistent with the biochemical experiments.Treatment with 50 μmol/L 6-OHDA for 8 h could significantly increased the generation of reactive oxygen species induced by 6-OHDA,while pretreatment with 1.0 mg/mL fucoidan for 1 h showed antagonism on that.Conclusion Fucoidan can protect MN9D cells from the death induced by 6-OHDA and the underlying mechanism may be involved in the antioxidant capacity of fucoidan.

OBJECTIVETo evaluate the therapeutic effect of hBNP on rats with chronic heart failure (CHF).
METHODSThirty CHF rats defined by echocardiography at 12 weeks post abdominal aortic constriction were randomly divided into Ad-hBNP group (2.5 × 10(10) VP/ml NS Ad-hBNP 1 ml/week × 4, n = 14), Ad-Track group (n = 8), placebo group (NS, n = 8), 10 sham-operated rats served as control group. After 4 weeks treatment, cardiac function was evaluated by echocardiography and hemodynamic measurements. Heart weight (HW) and HW/body weight (BW) ratio were determined.
RESULTSIVS, LVPW, LVEDD and LVESD were significantly reduced in the Ad-hBNP group [(2.34 ± 0.29) mm, (2.28 ± 0.18) mm, (6.50 ± 0.42) mm, (3.54 ± 0.59) mm] than those in the Ad-Track group [(2.71 ± 0.35) mm, (3.02 ± 0.85) mm, (7.71 ± 0.83) mm, (4.72 ± 0.80) mm] and in the NS group [(2.78 ± 0.23) mm, (2.83 ± 0.53) mm, (7.34 ± 0.97) mm, (4.55 ± 0.77) mm, all P < 0.05]. The LVEF and LVFS of the Ad-hBNP group [(79.27 ± 7.01)%, (43.38 ± 6.73)%] were significantly higher than in the Ad-Track group [(70.85 ± 4.81)%, (35.72 ± 3.68)%] and in the NS group [(69.67 ± 6.90)%, (34.91 ± 5.10)%, all P < 0.01]. HR [(417.48 ± 32.57) beats/min, (446.85 ± 61.49) beats/min, P < 0.05; (440.83 ± 32.18) beats/min, P < 0.05], LVEDP [(-4.24 ± 4.00) mm Hg (1 mm Hg = 0.133 kPa); (21.99 ± 6.80) mm Hg, P < 0.01; (18.00 ± 12.25) mm Hg, P < 0.01] were significantly decreased and while LVSP [(131.79 ± 15.76) mm Hg; (112.99 ± 32.35) mm Hg, P < 0.05; (117.13 ± 15.26) mm Hg], +dP/dt(max) [(5037.20 ± 430.41) mm Hg/s; (4217.40 ± 1354.15) mm Hg/s, P < 0.05; (4310.50 ± 1293.97) mm Hg/s, P < 0.05] and -dP/dt(max) [(-4382.00 ± 1304.79) mm Hg/s; (-3725.00 ± 791.34) mm Hg/s, P < 0.05; (-3890.00 ± 1043.73) mm Hg/s, P < 0.05]were significantly increased in Ad-hBNP group than in Ad-Track group and NS group (all P < 0.05). HW and HW/BW were also decreased in Ad-hBNP group than in the Ad-Track group and the NS group.
CONCLUSIONExogenous hBNP improved the cardiac function and attenuated remodeling in CHF rats.

Objective To validate the four chronic kidney disease epidemiology collaboration (CKD-EPI) predictive equations based on serum creatinine (SCr) and cystatin C (Cys C) in Chinese CKD patients,and try to develop the GFR predictive equations for Chinese CKD patients.Methods254 CKD patients were randomly selected from four Grade ⅢA hospitals in different regions in China from September 2007 to December 2010.Clearance of dual plasma sampling 99mTc-DTPA was used to measure glomerular filtration rate (rGFR) in 254 CKD patients.The serum concentration of Cr and Cys C were measured.CKD-EPI SCr equation,Cys C equation,Cys C equation adjusted for age,sex and race,SCr/Cys C combinated equation adjusted for age,sex and race were used to estimate GRF ( labeled as eGFR1,eGFR2,eGFR3 and eGFR4,respectively).The correlation,bias and precision of eGFRs were compared with rGFR by Wilcoxon signed rank test,intraclass correlation coefficient (ICC) and Spearman correlation analysis.The deviation degree between rGFR and different eGFRs was compared via Bland-Altman graph.The accuracy within 15%,25%,30% ( P15,P25,P30) and the staging correctness of eGFR against CKD at different stages was calculated.ResultsThe rGFR in 254 CKD participants was [ 48.07 (26.19 -92.97 )] ml · min -1·(1.73 m2) -1.The Spearman correlatiou coefficients (CC) of eGFR and rGFR varied within the range of 0.873 - 0.896 ( P =0.000 ).The intra-class CC ( ICC ) varied within the range of 0.920 - 0.942.The correlation of eGFR4 was the best.The absolute deviations of 4 eGFRs and deviation precision were eGFR4 <eGFR3 < eGFR2 < eGFR1.The 95% confidence intervals for the regression line of 4 eGFRs shown by Bland-Altman graphs were 92.5,87.3,83.0 and 76.1 ml · min-1 · ( 1.73 m2 ) -1,respectively,with the best result of eGFR4.For P30,the correctness of 4 eGFRs were eGFR4 > eGFR3 > eGFR2 > eGFR1,but no significant difference was found by Chi square test (x2 =6.448,P =0.092).The overall correctness rate in 4 eGFRs against CKD stages were 48.4% -57.5%,with the highest consistency of eGFR4,but their staging correctnessratewerenotideal(Kappa values were 0.405,0.348,0.366 and 0.463,respectively).Conclusions Compared with CKD-EPI SCr equation,no advantage was found in CKD-EPI Cys C equation.The Cys C equation adjusted by age and sex shows a little advantages over CKD-EPI Cys C equation in bias,precision,correlation and accuracy.The CKD-EPI SCr/Cys C combinated equation adjusted by age,sex and race has advantage over other three equations not only in bias,precision,correlation and accuracy,but also in staging correctness.However,the validation of this equation is still not fairly ideal for Chinese CKD patients.Based on these findings,it is essential for the Chinese CKD patients to develop SCr/Cys C combined predictive equation which adjusted by age,sex or other factors.(Chin J Lab Med,2012,35:798-804)

OBJECTIVETo evaluate clinical results of implant supported telescopic overdenture.
METHODS21 patients with edentulous jaws underwent telescopic overdenture restoration. A total of 28 prostheses were fabricated. Of them, 13 were in the upper jaws, 15 in the lower jaws. Among 139 placed implants, 74 were Camcog, 28 IMZ, and 37 Frialit-2. The secondary crown was fabricated by electroforming technique and wax-lost cast method. Clinical examination and radiographs were conducted. Changes in the marginal bone level around the implants were evaluated with radiograph. The mean follow-up time was 26.5 months (range 12 - 39 months).
RESULTSThis type of restoration could provide sufficient stability and maintain peri-implant hygiene easily. Peri-implantitis and prosthetic complications were not observed. Marginal bone around implants was stable. No implant was lost during the loading time.
CONCLUSIONSThe preliminary clinical results of this research showed that implant supported telescopic overdentures were predictable for edentulous patients.

OBJECTIVETo investigate the application of free medial sural artery perforator flap to reconstruct the defect following head and neck tumor ablation.
METHODSFrom April 2010 to January 2011, the defects after head and neck tumor resection were reconstructed with free medial sural artery perforator flaps in 16 patients. The clinical data were collected and analyzed, including site and histology of tumor, the skin paddle's size of the flap, the length of pedicle, the number of major perforators and donor-site morbidity.
RESULTSMedial gastrocnemius territories were evaluated before operation and free medial sural artery perforator flaps were used to reconstruct the defect after tumor ablation in 16 cases. One flap partially survived due to venous thrombosis. All of the other 15 flaps succeeded. The donor site was primarily closed in 15 cases and skin graft was applied in one case. All donor sites except one case healed in first intention. Long-term follow-up showed satisfying receipt-site reconstruction results with good functional and cosmetic outcome in the donor site. There was only minor sensory deficit in the donor site.
CONCLUSIONSThe medial sural artery perforator flap is reliable for reconstruction of the small to medium-sized defect in head and neck region with less donor site morbidity.
