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 collect data of fungi isolated from a fungus monitoring network in Hainan Province from 2013 to 2022, and analyze the drug resistance characteristics of Candida and the results of serological tests, with an aim to provide a basis for clinical diagnosis and treatment. Methods　In accordance with the National Fungal Drug Resistance Monitoring Network technical scheme, the qualifying fungal data were extracted from the microbial identification system database using SQL language, and the data information was then analyzed, with statistical processing done using SPSS 26.0 software. Results　Among 5 503 fungal isolates from clinical specimens between 2013 and 2022, cervical orifice secretions accounted for 30.37%(1 671 strains), mid-stream urine for 23.55%(1 296 strains), lower respiratory tract specimens for 25.24% (1 389 strains)[(sputum for 20.37%(1 121 strains) and alveolar lavage fluid for 4.87%(268 strains)], wound pus for 9.59%(528 strains), ascites for 5.60%(308 strains), blood for 3.67%(202 strains), cerebrospinal fluid for 0.38%(21 strains), and joint fluid for 0.04%(2 strains), with the highest number of strains isolated in 2022 and the lowest in 2013, the 2022 figure is about 2.6 times that of 2013. Among yeast-like fungi, Candida albicans had the highest proportion with 3 312 strains accounting for 60.2%; The highest resistance rate of Candida albicans was to fluconazole at 16.7%, with 2.5% being non-wild type (NWT) for amphotericin B; Candida tropicalis had the highest rate of resistance to fluconazole at 36.0%, with NWT at 41.1% for fluconazole and 3.1% for amphotericin B; Candida glabrata had a resistance rate to fluconazole of 2.8%, dose-dependent susceptibility (SDD) of 97.2%, NWT of 15.5% for fluconazole, and NWT of 8.6% for itraconazole; Candida parapsilosis had the highest resistance rate to fluconazole at 15.7% and and NWT of 8.3% for amphotericin B; Candida krusei had a 0.0% resistance rate to caspofungin; and Candida dubliniensis was 100.0% NWT to fluconazole. Of 70 cases of blood culture-positive specimens, 64 cases were detected by G test and 25 cases by Mn test, and the positive blood cultures were statistically significant when compared with the G test and Mn test, respectively (P<0.01). Conclusions　 Fungal serological test can make up for the deficiency of blood culture and distinguish fungal invasion and colonization, thus providing a basis for the effective control of fungal infection in clinical practice.

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.

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.

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.
