OBJECTIVE:To systematically review the efficacy of fluconazole in the treatment of candida infections in different parts,and provide evidence-based reference. METHODS:Cochrane library,Medline,EMBase,PubMed,CBM,CJFD,VIP data-base and Wanfang database were retrieved to collect the randomized controlled trial(RCT)of fluconazole(test group)vs. other an-tifungal agents(control group)in the treatment of candida infections in different parts. After information collection and quality eval-uation,the Meta-analysis was performed by Rev Man 5.1 software. RESULTS:There were totally 6 literatures included,involving 1 966 patients. Meta-analysis results showed that the effectiveness in test group was lower than control group in the treatment of can-didemia [OR=0.48,95%CI(0.29,0.77),P=0.003];compared with control group,there were no significant differences in the effec-tiveness in the treatment of esophagus candidemia [OR=1.15,95%CI(0.74,1.78),P=0.52]. CONCLUSIONS:The efficacy of flu-conazole in the treatment of candidemia is no better than anidulafungin and equivalent with amphotericin B;the efficacy of flucon-azole in the treatment of esophageal candidiasis is equivalent with itraconazole,voriconazole,anidulafungin and micafungin. Due to the limit of included studies,it remains to be further verified by high-quality,large-sample and long follow-up RCTs.

Objective To study the expression of tight junction factors in human placental tissues derived from assisted reproductive technology (ART) and natural pregnancy and its role in placental barrier.Methods Ten placental samples were collected from the women who had undergone ART treatment and 11 placenta were collected from control group.Transmission electron microscope (TEM) examination was utilized to detect the morphology of placental tight junctions.The mRNA of claudin (CLDN) 1,CLDN4,CLDN5,CLDN8,zonula occudens (ZO) 1 was detected by real-time PCR and the protein of CLDN4,CLDN8 and occludin (OCLN) were measured by western blot.Results TEM microscopy results showed that placenta samples derived both ART and control placenta had normal microscopic histological features of tight junctions,localized in the apical part of the syncytium and also between the cell-cell contacts of fetal blood vessel endothelial.The expression level of CLDN4 mRNA were 0.87 ±0.17 in ART group and 1.18 ± 0.30 in control group,respectively.The expression level of CLDN8 mRNA were 3.25 ± 2.32 in ART group and 1.08±0.41 in control group,respectively.The mRNA level of CLDN4 and CLDN8 were significantly differentially expressed in ART derived placenta when compared with control groups.The expression level of CLDN1,CLDN5,OCLN and ZO1 mRNA were 0.49 ± 0.44,0.80 ± 0.20,0.92 ± 0.18 in ART group and 1.09±0.82,1.21 ±0.78,0.80± 0.27 in control group,respectively,in which there were no significant differences between two groups.Western Blot analysis showed the protein levels of tight junctions CLDN4,CLDN8 and OCLN did not differ between groups.Conclusions Tight junction factors were expressed in human placental tissues.Tight junction derived from ATR platenta might have mild dysfunction.

Objective To understand the intensity and characteristics of acute toxicity of esculentoside A on mice and measure relevant parameters and observe its diuresis effect on rat. Methods After intraperitoneal injection of different concentrations of esculentoside A to mice, toxic reactions were observed. Rats with water load were intraperitoneally injected with different doses of esculentoside A. Total urine volume in six consecutive hours after the injection was determined. Results The LD50 of esculentoside A calculated by Bliss method was 26. 19 mg · kg-1 , and the 95% confidence interval was 23. 11-29. 85 mg·kg-1 . The mortality and acute toxicity of esculentoside A appeared to be dose-dependent while the blank control group had no abnormal reaction. The urine volume was significantly different between high dose group and the negative control group. No significant difference in urine volume was found between middle and the negative control group, and between low dose group and the negative control group. Conclusion Esculentoside A is poisonous to mice when single dose was intraperitoneally injected, and high dose of esculentoside A has diuresis effect on rat.

Objective To explore the risk factors of cognitive impairment of elderly patients with cerebral infarction in order to provide the theoretical basis for the clinical intervention. Methods A total of 237 cases with senile cerebral infarction were selected as ours subjects who were hospitalized from Mar. 2010 to Jun. 2013 in Kailuan General Hospital Affiliated to Hebei United University. The general condition and medical history were recorded. The auxiliary examination was performed. Cerebral infarction was diagnosed based on the onset to diagnosis standard and MoCA scores of within 2 weeks. The patients with less than 26 MoCA score were diagnosed as cognitive dysfunction and otherwise were thought as normal. Single factor analysis methods and non conditional Logistic regression were applied to analyze the analysis. Results There was no significant difference in terms of incidence between patients with different gender. Patients with age more than 75 years old and lower education levels had the high incidence rate than those with younger age and high education levels( χ2=16. 661,5. 453;P﹤0. 05). The cognitive dysfunction incidence of patients with white collar was lower than those with blue collar(χ2 = 5. 458,P ﹤ 0. 05 ). And the cognitive dysfunction incidence of patients with hypertention,diabetes,heart disease and leukoaraiosis were higher than those without the above diseases(χ2 =28. 423,5. 621,7. 768,6. 070;P﹤0. 05). The incidence of patients smoking more was significantly higher than that of smoking less or no(χ2 =5. 045,P ﹤0. 05 ). Multiple factors and non conditional Logistic regression analysis showed that,67 Senile cerebral infarction patients occurred cognitive impairment within 2 weeks. The independent risk factors for its occurrence included age greater than 75 years( P=0. 000 ),diabetes mellitus( P=0. 043),hypertension(P=0. 000)and leukoaraiosis(P=0. 041). Conclusion There are many risk factors related to cognitive impairment after cerebral infarction occurred in the elderly.
