Mycotic vaginitis is a common and frequently-occurring gynaecopathia and easy to attack repeatedly, so painful to patients. In this study, the authors observed the clinical efficacy of Sophora gel combined with Fluconazole capsules in treating mycotic vaginitis, in order to seek an effective method for treating mycotic vaginitis. Totally 85 patients with mycotic vaginitis treated in our hospital between December 2012 and July 2014 were randomly divided into the treatment group (43 patients) and the control group (42 patients). The treatment group was given vaginally Sophora gel (one piece every night for 14 days) and orally Fluconazole capsules (150 mg, once every three days, four times in total); The control group was only administered with Fluconazole capsules. The total efficacy, cure rate, recurrence rate and clinical symptom improvements of the two groups were observed. The results show that the total efficacy, the cure rate and the recurrence rate of the treatment group vs. the control group were respectively 97.7%, 90.7% and 2.6% vs. 83.3%, 71.4% and 20.0%, with statistical significance in their differences (P < 0.05). The treatment group showed reduced leucorrhea, pruritus vulvae disappearance and earlier mucosal hyperemia disappearance than the control group, with statistical significance in their differences (P < 0.05). In conclusion Sophora gel combined with Fluconazole capsules can improve antifungal activity of drugs, relieve clinical symptoms, shorten the course of disease, enhance the cure rate and reduce the recurrence rate; So this therapy can be widely applied in clinic.

Objective To determine the levels and significance of Krebs von den lungen-6(KL-6), pulmonary surfactant protein A (SP-A), SP-D and interleukin (IL)-6 in patients with connective tissue disease interstitial lung disease (CTD-ILD). Methods The serum KL-6, SP-A, SP-D and IL-6 in all subjects were detected and the imaging and pulmonary function were recorded t test, χ2 test, non-parametric test, ANOVA and correlation analysis were used for data analysis. Results ① The levels of serum KL-6, SP-A, SP-D, IL-6 in the CTD-ILD group [551.4 (428.2, 883.5) U/ml, 938.4(435.2, 2324.7) pg/ml, 90.7 (80.7, 100.3) ng/ml and 30.4 (22.9, 41.7) pg/ml; P all<0.05] was significantly higher than that in the CTD group [192.9 (139.2, 266.2) U/ml; 458.0 (372.6, 529.0) pg/ml; 80.0 (71.2, 98.3) ng/ml; 18.6 (4.9, 31.0) pg/ml, Z=-5.383, -3.76, -2.123,-3.903, P all <0.05]; and higher than healthy controls (n=30) [183.2(141.9, 216.6) U/ml; 229.0(162.0, 248.0) pg/ml;50.8(26.1, 96.4) ng/ml;7.1(3.7, 8.7) pg/ml, Z=-5.801,-8.13, 2.272, 3.266;P all<0.05].②The levels of KL-6 in pulmonary HRCT for active ILD group was significantly higher than the non-active ILD group [998.5 (640.3, 1293.3) U/ml vs 565.0(434.0, 799.5) U/ml, Z=2.182, P=0.023], there was no statistical difference in the levels of SP-A, SP-D, IL-6 between the 2 groups. ③ Spearman correlation analysis showed that KL-6 was negatively correlated with forced vital capacity (FVC%);SP-D, IL-6 and diffusing capacity of carbon monoxide (DLCO %). ④ Logistic multiple regression analysis showed that KL-6 [OR=1.017, P=0.002, 95%CI (1.006, 1.028)], SP-A [OR=1.023, P=0.009, 95%CI (1.006, 1.041)], SP-D [OR=1.175, P=0.009, 95%CI (1.075, 1.264)], IL-6[OR=1.213, P=0.001, 95%CI(1.088, 1.354)] were the risk factors for ILD. Conclusion Serum KL-6, SP-A, SP-D and IL-6 are significantly increased and correlate with CTD-ILD. KL-6 is related to the pulmonary inflammatory disease and vital capacity, while SP-D and IL-6 are related to diffusion function.

BACKGROUND:Recombinant adeno-associated virus serotype 9 has a high affinity in myocardial tissue, and the expression of recombinant adeno-associated virus serotype 9-enhanced green fluorescent protein (rAAV9-eGFP) in the aorta of atherosclerosis mice is not clear. OBJECTIVE:To explore the optimal time point of rAAV9-eGFP expression in the aorta of atherosclerosis mice. METHODS:Atherosclerosis model was established with high-fat diet in 30 ApoE-/-mice for 16 weeks. Among them, 25 mice were injected with 5.0×1011 vg (virus genomes) rAAV9-eGFP through the tail vein, while the remaining 5 mice were injected with saline, serving as the control group. The virus-transfected mice were kil ed at 14, 21, 28, 35 and 60 days after transfection, and aortic tissue was harvested. The expression of enhanced green fluorescent protein was detected with laser scanning confocal microscope. Western blot assays were used to detect the expression of enhanced green fluorescent protein in aorta. The expression of enhanced green fluorescent protein in vivo was observed and the optimal expression time point was determined. RESULTS AND CONCLUSION:rAAV9-eGFP effectively transfected the aorta of atherosclerosis mice, enhanced green fluorescent protein was expressed in aortic tissue, and the expression intensity increased gradual y with the increasing transfection time. The highest expression level was found at 35 days after transfection and then maintained stable at 60 days. There were significant differences at different time points after transfection (P<0.001). These data indicate that rAAV9-eGFP can be effectively expressed in the aorta of atherosclerosis ApoE-/-mice and rAAV9-eGFP can be regarded as the optimal vector in the treatment of atherosclerosis.

BACKGROUND:Cyclin A2 is a key regulator of cellcycle. Location and expression of cyclin A2 in neonatal mouse myocardium is not clear.
OBJECTIVE:To observe the location and expression of cyclin A2 in neonatal mouse cardiomyocytes and its relationship with the exit of cardiomyocytes from cellcycle.
METHODS:Neonatal mice were kil ed to take myocardial tissues at 0, 3, 7, 14 and 28 days after birth. Western blot were used to detect the expression of cyclin A2, proliferating cellnucleus antigen and Phospho-histone H3. Immunohistochemitry detection was used to detect the location of cyclin A2 and expression of proliferation cellnucleus antigen at different time after birth.
RESULTS AND CONCLUSION:Western blot showed the decrease of cyclin A2 after birth til disappeared at day 4 (P=0.001). Cyclin A2 located mainly in the nucleus after birth and exported to the cytoplasm at day 14, and basical y disappeared at day 28. Proliferating cellnucleus antigen showed gradual y decreased tendency after birth. Mitosis specific marker, Phospho-histone H3, exhibited a gradual decrease after birth, which was consistent with cyclin A2 in expression intensity.

BACKGROUND:The formation of atherosclerotic lesions in apolipoprotein E knockout mice is similar to that of human systemic atherosclerosis, and apolipoprotein E knockout mice are ideal animals for current establishment of atherosclerosis models.
OBJECTIVE:To research the pathological process of atherosclerosis in apolipoprotein E knockout mice aged different weeks, and to explore the effect of different diets on the occurrence and development of atherosclerosis in apolipoprotein E knockout mice.
METHODS:Male apolipoprotein E knockout mice aged 8 weeks old were randomly divided into two groups, and fed with high fat diet and normal diet, respectively, for 8, 12, 16, 20, and 24 weeks.
RESULTS AND CONCLUSION:Serological detection revealed that serum total cholesterol, triglycerides and low density lipoprotein levels were significantly higher in different weeks of mice of high fat diet group than in the normal diet group (P<0.05), in a time-dependent manner. Gross and frozen oil red O staining showed that atherosclerotic plaque area of lumen was significantly larger in the high fat diet group than in the normal diet group (P<0.05), in a time-dependent manner. At this time, significant differences in plaque area of lumen at each week were detected between both groups (P<0.05). Apparent lipid plaque was visible in aorta at 16 weeks of high fat diet in mice. Results demonstrated that apolipoprotein E knockout mice of atherosclerosis were successful y established. The formation of lipid streaks and fiber hyperplasia was faster in high fat diet group than in the normal diet group.

Objective To develop an early-warning indicator system of brucellosis outbreak. Methods The methods of literature review and expert discussion were used to formulate the initiatory framework and indicators, and then Delphi method was used to filter indicators, discuss the boundary of indicators and determine the weighting coefficient. Results The average length of service provided by experts who engaged in prevention and control of brucellosis was (25.10 ± 8.80) years and the positive coefficient of the consultant experts of the two-round results were 95% and 68%, respectively. Kendall coefficients were 0.35, 0.54 and X2R value were 81.31 and 285.27, respectively and P value was all less than 0.01. Five first-level indicators(the host animal, high-risk groups,social environment, index case and the level of previous disease) and 13 secondary indicators were selected to develop the early-warning indicator system of brucellosis outbreak. The weight coefficients of the five first-level indicators were 0.21, 0.22, 0.17, 0.21 and 0.19, respectively. Conclusions The early-waming indicator system of brucellosis outbreak is initially established. We propose to develop the early-warning programs according to local conditions and the indicator system.
