Objective To observe the efficacy of pregabalin in the treatment of painful diabeticperipheral neuropathy.Methods In a 8-week study,50 patients were randomly assigned into two groups:the therapy group and the control group.The patients in the therapy group were treated with pregabalin 150 mg/d,and the patients in the control group were treated with carbamazepine 200 mg/d.The dose of pregabalin was increased to 300 mg/d till pain was alleviated in the therapy group,and the dose of carbamazepine was increased to 600 mg/d till pain was alleviated in the control group.The therapeutic effect and VAS score in the two groups were observed and evaluated.Results After 1 and 8 weeks' treatment,the therapeutic effect of therapy group were significantly superior to the control group ( At 1 week:U =2.028,P =0.046 ; At 8 week:U =3.540,P <0.001 ).After 1 and 8 weeks' treatment,the VAS scores of therapy group were significantly lower than the control group ( At 1 week:5.13 ± 1.76 vs.6.74 ± 1.52,P < 0.05 ; At 8 week:1.13 ± 0.45 vs 3.27 ± 1.04,P < 0.05).There were 5 patients (20%) and 10 patients (40%) had adverse reaction in the therapy and the control groups respectively.Conclusion Pregabalin is effective and safe for the treatment of painful diabetic peripheral neuropathy.

Objective To investigate the level and proportional relationship of free fluorine and soluble fluoride in different brands of toothpaste,and analyze possible risk factors.Methods A total of 54 samples of commercially available toothpastes of domestic,joint venture and imported in Guiyang City were collected,and the levels of free fluoride and soluble fluorine were determined,respectively,using fluorideion selective electrode.method (GB 8372-2008).Results The number of the toothpaste was 32,12,10,respectively,in domestic,joint venture and imported.The levels of free fluorine ranged from 0.98 to 1 603.50 mg/kg,3.22 to 617.50 mg/kg and 306.80 to 1 590.80 mg/kg,respectively,in toothpastes of domestic,joint venture and imported; the number of exceeding the standard free fluorine was 3,0 and 1,respectively,in toothpastes of domestic,joint venture and imported; the rate of exceeding the standard free fluorine was 9.4%,0.0% and 10.0%,respectively,in toothpastes of domestic,joint venture and imported.The levels of soluble fluorine ranged from 3.06 to 4 302.50 mg/kg,9.02 to 1 667.30 mg/kg and 9.18 to 4 013.20 mg/kg,respectively,in toothpastes of domestic,joint venture and imported; the number of exceeding the standard soluble fluorine was 9,2 and 3,respectively,in toothpastes of domestic,joint venture and imported; the rate of exceeding the standard soluble fluorine was 34.4%,16.7% and 30.0%,respectively,in toothpastes of domestic,joint venture and imported.The proportion of free fluorine and soluble fluoride was:domestic 1.0 ∶ 2.7,joint venture 1.0 ∶ 2.7,imported 1.0 ∶ 2.5,respectively.The confidence limit (R/d) was 0.98.Conclusion The fluoride level in different brands of toothpaste has exceeded the standard,the content and proportion of soluble fluoride are obviously higher than those of free fluoride,and there is a risk on tooth damage from fluoride,and factories should strengthen quality control in adding fluoride.

Objective To evaluate the therapeutic efficacy and its related factors of entecavir treatment for patients with acute on chronic hepatitis B liver failure (ACHBLF).Methods One hundred and eight patients with ACHBLF were enrolled and divided into entecavir group (n=53) and control group (n=55).HBV DNA level, liver function and 48-week survival rate were observed, and C ox regression model was established to identify the factors which may affect the efficacy of entecavir treatment.Results Totally 70 patients died in the study and 66 died within 12 weeks.The statistical difference on cumulative survival rate between two groups was observed from the third week on (χ2=5.357, P < 0.05).The 48-weekcumulative survival rate in entecavir group was 47.2% (25/53), while that in the control group was 23.6%(13/55) (χ2=7.432, P < 0.01).In entecavir group, for patients aged < 40 with serum bilirubin level <513 μnol/L and international normalized ratio (INR) < 2.5, the fatality rates decreased 74.9%, 75.3%and 76.0%, respectively.Conclusions Entecavir may improve the survival rate of patients with ACHBLF.Age, serum bilirubin level and INR are major factors related to the therapeutic efficacy.

Objective To investigate the balance of Th1/Th2 cytokines and its relationship with prognosis of severe chronic hepatitis B ( CHB ). Methods Peripheral blood samples were collected from 112 severe CHB patients, 30 CHB patients and 30 healthy controls. IL-4, IFN-γ levels and HBV DNA loads were measured by ELISA and fluorescent PCR, respectively. The levels of cytokines in different stages, and their correlations with HBV DNA loads and short-term prognosis were analyzed. Results Higher levels of IL-4, IFN-γ and Th1/Th2 ratios in peripheral blood were detected in patients with severe CHB than those with CHB and the healthy controls (Z = 8.968, 10. 004 and 26. 067, P =0. 009, 0. 007 and 0. 000). IL4 levels in patients with end-stage server CHB were markedly higher than those in other stages ( Z = 3. 672 and 3. 158, P= 0.000 and 0.002), while their Thl/Th2 ratios were lower (Z=3. 161 and 2. 166, P=0.002 and 0. 030). No significant differences on levels of IL-4, IFN-γ and Th1/Th2 ratios were observed in severe CHB patients with different HBV DNA levels (Z =4.431, 2.626 and 0. 140, P =0.219, 0.403 and 0. 987). Elevated IL-4 was closely correlated with the high case-fatality rate within 12 weeks. Conclusions The balance between Th1 and Th2 cytokines is- disturbed in patients with severe CHB. Thl/Th2 ratio decreases with the aggravation of diseases, which may indicate unfavorable short-term prognosis.

OBJECTIVETo study the function of the chalcone synthese gene introns in Scutellaria baicalensis, and clarify preliminarily their role in abiotic stress.
METHODThe CHS introns with specific primers were cloned and bioinformatic method was applied to predict the cis-elements in the intron of CHS. The introns were subcloned into binary vector, pCAMBIA-1301 before being transferred to tobacco. Then the activity of GUS of the transgenic tobacco seeds was analyzed.
RESULTSeven cis-elements were found in the introns. Under the dark and high temperature GUS expression rose at the first (3 h), but then declined (9 h). ABA and MeJA regulated insignificantly the GUS activity in normal temperature; treatment of 10% PEG induced GUS expression.
CONCLUSIONCHS introns could be play a role in the regulation of S. baicalensis phenylpropanoid biosynthetic pathway.

Objective To validate the value of Cleveland Clinical Score in predicting acute renal injury requiring renal replacement therapy(RRT-AKI) after cardiac valve surgery in Chinese adult patients.Methods An analysis was conducted for all the adult patients who underwent cardiac valve surgery from January 2010 to December 2014 in Changhai Hospital,Shanghai.A total of 3 230 adult patients were included.Based on Cleveland Clinical Score,the patients were divided into 3 risk stages:0 to 2 point,3 to 5 point,and 6 to 8 point.The incidence of RRT-AKI were compared between different stages.And the predictive value of the Cleveland Clinical Score model was assessed by area under the receiver operating characteristic curve(AUC-ROC) and the model calibration was assessed using the Hosmer-Lemeshow test.The patients were also divided into two groups:Non-RRT group and RRT-AKI group.The mortality were compared between these two groups.Results The incidence of RRT-AKI was 1.67% vs the predicted ratio of RRT-AKI 1.70% (x2 =0.018,P =0.892).Among the stage 1,2,and 3,the actual incidence of RRT-AKI,was 1.23%,2.66%,and 16.7% vs the predicted incidence 0.40%,1.80%,and 9.50%,respectively.The AUC-ROC for Cleveland Clinical Score predicting RRT-AKI was 0.64 [95 % CI(0.57,0.71),P <0.01].Compared with Non-RRT group,the RRT-AKI group got a higher mortality(87.00% vs 1.50%,x2 =1 330,P <0.01).Conclusion The Cleveland Clinical score had no real predictive value for RRT-AKI in Chinese adult patients after cardiac valve surgery.The incidence of RRT-AKI of the whole population and the stage 3 patients could be predicted by the model.And the patients with a high Cleveland score got a higher mortality than that of patients with a low Cleveland score.
