To investigate the expression of vaginal Th1 and Th2 cytokines in rats with experimental vaginal candidiasis under different immune conditions, ICR murine vaginal candidiasis model was established and immno-suppressed murine models of vaginal cadidiasis were established in estrogen-treated mice. Non-estrogen-treated mice were used as controls. The mRNA level of Th1 (IL-2)/Th2 (IL-4, IL-10, TGF-beta1) cytokines in murine vaginal tissues was determined by RT-PCR. The cykotine in local tissues was increased to different extent under normal immune condition. IL-2 mRNA was increased during early stage of infection, while IL-10 was increased transiently during late stage of infection. TGF-beta1 production was found to be increased persistently. At same time, the expression of IL-2 mRNA was suppressed in immno-suppressed group, and the level of IL-4, IL-10, and TGF-beta1 were higher than the normal immunity group to different degree during infection. The high level of IL-2 mRNA during early stage of infection was associated with clearance of mucosal Candidia albicans (C. albicans), and its expression suppressed leading to decreased clearance of mucosal C. albican in immuno-suppression. The over-expression of IL-4 and IL-10 could significantly enhance the susceptibility to C. albicans infection in mice.

Objective In children with neurogenic bladder and secondary vesicoureteral reflux , we ex-plore the differences of urodynamics between the children with and without detrusor overactivity (DO). The study is in order to provide theoretical support for clinical practice. Method From January 2013 to March 2016, 110 children with NB vesicoureteral reflux diagnosed by videourodynamics were recruited. There are 63 boys and 47 girls aged 4-12 years with mean of 7.5 years. According to presence of DO during the filling phase, the patients were divided into DO (n=32) and non-DO groups (n=78). The time of bladder ureter reflux perfusion and detru-sor pressure were recorded for calculation of bladder compliance when the reflux occurs in the two groups. Maximum cystometry capacity and maximum detrusor pressure were recorded for calculation of the bladder compliance at the end of filling in the two groups. According to the reflux flow level, patients were divided into mild reflux (Ⅰ-Ⅱdegrees), severe reflux (Ⅲ-Ⅴdegrees). The difference of reflux side of the two groups and reflux degree were an-alyzed. Result In DO group, bladder capacity and compliance were (107.5 ± 21.3) mL and (5.6 ± 1.8) mL/cmH2O, respectively, when bladder ureter reflux occurs. In non-DO group, the bladder ureter reflux bladder capac-ity and compliance were (124.7 ± 35.6) mL, (6.7 ± 2.3) mL/cmH2O. The two parameters were significantly differ-ent in both groups. In DO and non-DO groups, the detrusor pressure were (21.7 ± 8.3) cmH2O and (19.6 ± 9.2) cmH2O, respectively, which does not have any significant statistical difference. At the end of filling, bladder capac-ity and compliance in DO group were (198.7 ± 36.5) mL, (5.8 ± 1.9) mL/cmH2O. In non-DO group, bladder ca-pacity and compliance were (223.8 ± 40.2) mL and (6.5 ± 1.4)mL/cmH2O. In both group, there are difference. In DO group, there are 20 cases of unilateral reflux (63%) and 12 cases of bilateral reflux (37%). In non-DO group, there are 31 cases of unilateral reflux (40%) and 47 cases of bilateral reflux (60%). The reflux of the two groups are also serious. Conclusion Small bladder capacity and poor bladder compliance are the urodynamic characteris-tics of children with NB and secondary vesicoureteral reflux when DO occurs.

To compare the therapeutic effects of three different anti-fungal drugs (i.e., terbinafine, fluconazole and intraconazole) in the treatment of experimental vaginitis caused by Candida albicans (C. albicans) in mice, the fungal vaginitis model was established in female ICR mice by intravaginal inoculation of suspension of C. albicans after the animal had been pretreated with estradiol. Mice were divided at random into different groups and then respectively treated with terbinafine, fluconazole and intraconazole given by gastrogavage. The burden of the fungus in the vaginal lavage fluids in the mice of the different groups was measured dynamically at different time points after the beginning of the drug treatment. The fungal burdens in the vaginal lavage fluids taken at different time points from the mice treated with terbinafine were significantly higher than those taken at corresponding time points from mice treated with fluconazole or itraconazole (P<0.01). The fungal burdens in the vaginal lavage fluids taken from mice 1 week after the beginning of the treatment with terbinafine remained at a relatively high level. A dramatic drop in the fungal burden was noted in the vaginal lavage fluids taken on the 2nd day of the treatment from mice treated with itraconazole or fluconazole group and the fungal burden on the 3rd day of the treatment in these mice were at a very low level, suggesting that fluconazole or itraconazole were highly effective for the treatment. However, the difference in the therapeutic effect between the two drugs was not significant (P>0.05). Itraconazole or fluconazole, but not terbinafine, is very effective for the treatment of fungal vaginitis caused by C. albicans in mice.

Corneal opacity is one of the most commonly used parameters for estimating postmortem interval (PMI). This paper proposes a new method to study the relationship between changes of corneal opacity and PMI by processing and analyzing cornea images. Corneal regions were extracted from images of rabbits' eyes and described by color-based and texture-based features, which could represent the changes of cornea at different PMI. A KNN classifier was used to reveal the association of image features and PMI. The result of the classification showed that the new method was reliable and effective.

To study the relationship between the late postmortem interval (PMI) and trimethylamine-nitrogen (TMA-N) in postmortem tissues of cadaver, TMA-N in muscles, livers and kidneys of rats was measured at different postmortem intervals (PMI) by using a modified spectrophotometric method. The results indicated that the detection sensitivity of TMA-N was 1 mg/L, and there was a good linear correlation between the value of absorbance (A value) and TMA-N at the concentration of 1-10 mg/L (R (2) = 0.9991). Although TMA variation in muscles was different from that in inner organs during the time since death, TMA-N changes in cadaver tissues was positively correlated with PMI. During 2 to 7 d since death, the best correlation between PMI and TMA-N concentration was found in muscles. With PMI as an independent variable, the cubic polynomial regression equation was y= -0.457x(3)+6.519x(2)-24.574x+27.207 (R (2)=0.969). During 3 to 8 days since death, PMI was best correlated with TMA-N concentration in inner organs. With PMI as the independent variable, the cubic polynomial regression equation was y=0.509x(3)-9.153x(2)+55.727x-95.819 (R (2)=0.953). It was concluded that TMA-N in tissues could be used as a new estimator for late PMI. The method used in this study offered advantages such as accuracy, sensitivity, little samples required and wide PMI estimation.

Objective: To analyze the effects of technetium99 conjugated with methylene diphosphonate(99Tc-MDP) on adjuvant arthritis in rats.Methods: Thirty SD rats were randomly and equally divided into a normal control group an adjuvant arthritis control group and a 99Tc-MDP treatment group.Intraperitoneal injection of 99Tc-MDP(2.5?10-3?g/kg) was given to the rats in the treatment group on the tenth day and repeated every other day after arthritis induction.The left-right diameter of the left hind ankle,arthritic index,serum TNF and IL-1? levels,articular radionuclide imaging and histopathological changes were observed.Results: Compared with the adjuvant arthritis group,the diameter of the left hind ankle,arthritic index,the serum TNF and IL-1? levels and the T/NT value were decreased in the treatment group,and histopathology showed less synovium hyperplasia and fewer infiltration of inflammatory cells in the group treated with 99Tc-MDP intraperitoneal injection than in the adjuvant arthritis control group.Conclusion: 99Tc-MDP intraperitoneal injection is effective for adjuvant arthritis in rats.

OBJECTIVE To explore the expression of long non-coding RNA (LncRNA) HOTAIR, enhancer of Zeste homolog 2 (EZH2) and vascular endothelial growth factor (VEGF) in nasopharyngeal carcinoma (NPC) and their relationship between HOTAIR and prognosis. METHODS We examined the expression of HOTAIR, EZH2 and VEGF in NPC tissues, and analyzed the clinical significance of HOTAIR expression in patients with NPC. RESULTS We found that the expression of HOTAIR, EZH2 and VEGF in the NPC tissues were significantly higher than those in the chronic nasopharyngitis tissues in the gene and protein levels (U=955,P<0.05). The HOTAIR was positively correlated with VEGF (r=0.599,P<0.001), VEGF was positively correlated with EZH2 (r=0.369, P=0.012), and HOTAIR had no significant correlation with EZH2 (r=0.139,P=0.357). Moreover, HOTAIR expression levels increased with clinical stage progression. CONCLUSION The expression of HOTAIR, EZH2 and VEGF were significantly increased in the NPC tissues, and the expression of HOTAIR was related with the TNM stage, the clinical stage and the short term therapeutic effect of the NPC patients, which indicated that the HOTAIR might be used as a biological indicator to determine the prognosis of the NPC.
