Chinese Journal of Primary Medicine and Pharmacy 2008;15(6):979-981
Objective To evaluate the cost-effectiveness of four therapeutic regimes in the treatment of pa-tients with initial vulvovaginal eandidiasis. Methods 160 patients who were found for the first time with vulvovagi-hal eandidiasis were divided into four groups randomly: group A is clotrimazole (500rag) vaginal tablets; group B is fluconazole eaptica;group C is clotrimazole vaginal tablets combined with flueonazole;group D is nystatin vaginal ef-fervescent tablets. Date was evaluated using clinic economies co,t-effectiveness analysis. Results Among four groups,the costs for group A,B,C and D were 167.20 yuan, 190.23 yuan,237.43 ynan and 216.40 yuan,respec-tively. The tatol effective rates were 90.88 %, 90.12 %, 91.67 % and 67.10 %, respectively. The cost-effectiveness ratio were 1.84,2.11,2.59 and 3.23, respectively. The incremental cost-effectiveness ratios of group B, C and D vs group A were 32.90,87.78 and 2.07. Conclusion Regime A was superior than the other therapeutic regimes.

Tianjin Medical Journal 2015;(12):1433-1436
Objective To investigate the associations of alcohol consumption with the outcome of three-year pre-dia?betes. Methods The objects of this study were selected from the epidemiological study of cancer risk of Chinese patients with type 2 diabetes mellitus (T2DM) in Luzhou area. A total of 1 125 cases with pre-diabetes were selected from the base?line survey. Patients divided into four groups including non-alcohol drinking group, small alcohol drinking group, moderate alcohol drinking group, and large alcohol drinking group. Patients also were divided into two groups according to body mass index (BMI, more than 24 kg/m2). The patients were followed up for three years. The incidence rates of diabetes mellitus were compared between different drinking groups and different BMI groups. Results A total of 1 116 cases were completed the follow-up , 9 cases were lost to follow-up. The incidence rates of DM were 18.81%, 8.80%, 16.51%and 26.53%for non-al?cohol drinking group, small alcohol drinking group, moderate alcohol drinking group, and large alcohol drinking group. Cox proportional hazard regression analysis showed that the relative risk ratios and 95%CI of the gender, age, BMI, calorie, base?line blood glucose were 0.49 (0.31-0.79), 1.15 (0.69-1.92) and 1.95 (1.25-3.04) for small alcohol drinking group, moderate alcohol drinking group, and large alcohol drinking group. In the group of BMI<24 kg/m2,the relative risks and 95%CI were 0.40 (0.20-0.80),0.77 (0.30-1.97) and 1.10 (0.46-2.64) for small alcohol drinking group, moderate alcohol drinking group, and large alcohol drinking group. In the group of BMI≥24 kg/m2, the relative risks and 95%CI were 0.62 (0.33-1.66),1.49 (0.80-2.80) and 2.64 (1.55-4.47). Conclusion Small amount of alcohol drinking can reduce the incidence of DM in predia?betes people with BMI<24 kg/m2. Large amount of alcohol drinking is the risk factor of incidence of DM in people with BMI≥24 kg/m2.

Objective To investigate the clinical value of contrast-enhanced ultrasonography(CEUS) in evaluating treatment response of hepatocellular carcinoma after interventional therapy. Methods One hundred and three patients with 136 lesions of hepatocellular carcinoma confirmed by pathology were examined by common color ultrasound (US), contrast-enhanced CT, CEUS and DSA pre- and post-interventional treatment respectively. Results The sensitivity,specificity and accuracy of CEUS for focus judgment after interventional therapy were 95.8%, 95.6% and 98. 5% respectively. The sensitivity, specificity and accuracy of US in detecting tumor deactivation and residue were 92.3% ,77.4% and 83.1% respectively. CEUS were highly consistent with the results of enhanced CT/DSA (Kappa = 0.93) and significantly higher than those of US (Kappa = 0.66). Conclusions CEUS is useful to monitor the efficacy and guide treatment after interventional therapy.
