ABSTRACT
Objective To investigate the effect of cefuroxime axetil on vaginal microecological balance in mice.Methods Twenty specific pathogen free (SPF)female mice were randomly divided into experimental group A and B and control group C and D with 5 mice in each group.Mice in experimental groups A and B were given dissolved cefuroxime axetil by gavage for 5 days,mice in the control groups C and D were given 0.9% saline instead.Vaginal secretions from experiment group A and the control group C were collected on d1 after drug withdrawal,and from experiment group B and control group D were collected on d5 after drug withdrawal.The vaginal pH,Lactobacillus,Enterobacter,Staphylococcus and Streptococcus colony forming units (CFU)were measured,and the ultrastructure of Lactobacillus was observed with scanning electron microscope (SEM).The density and diversity of vaginal flora were determined.t test and Z test were used to analyze data.Results Compared to control group C,vaginal pH was increased in experimental group A on d1 (t =2.675,P <0.05 ),and CFU of Lactobacillus,Enterobacter,Staphylococcus and Streptococcus decreased significantly (t =-2.741 , -1 3.501 , -3.077 and -2.598,all P <0.05 );compared to control group D,vaginal pH in experimental group B was increased on d5 (t =4.797,P <0.05),and CFU of Lactobacillus,Enterobacter,Staphylococcus and Streptococcus decreased significantly (t =-3.737,-6.81 6, -1 6.079 and -3.580,all P <0.05 ).The morphology of Lactobacillus showed wrinkled,broken cell wall and cell debris in experiment groups A and B under the electron microscope.The density and diversity of vaginal florain experimental groups A and B were decreased compared to those in control groups C and D (Z = -2.437 and -2.297,both P <0.05 ).Conclusion Broad-spectrum antibiotics cefuroxime axetil can increase vaginal pH, destroy the cell wall of dominant bacterial Lactobacillus,and reduce vaginal flora diversity and density,resulting in disturbance of vaginal micro-ecologicalbalance.
ABSTRACT
[Objective] To observe the clinical effect of Bupleurum injection external application applied to female genital condyloma accuminatum cases. [Methods] From January 2010 to June 2013,we studied 60 female genital condyloma accuminatum cases in the outpatient department of our hospital, these cases were randomly divided into two groups:group A(Bupleurum injection group) and group B(ShuRun suppository, namely a-2a interferon suppository group), the clinical curative effect of the two groups was observed. [Results] After treatment, group A,30 cases in al ,9 cases had complete recovery,12 cases had some effect,9 cases were invalid, the total effective rate was 70%; group B,the total of 30 cases,6 cases had complete recovery, 7 cases had some effect, 17 cases were invalid, the total effective rate was 43.3%, group A in the treatment of female genital condyloma acuminatum had better effect than the group B(P0.05). [Conclusion] Bupleurum injection for treating female genital condyloma acuminatum has better clinical efficacy, can be considered for clinical use.
ABSTRACT
[Objective]To probe into the immune protective effect of Astragalus polysaccharide on mice ,whose genital tract was infected with Chlamydia trachomatis. [Methods]After the murine model of genital tract infected with chlamydia trachomatis was established, we could obtain the minimum effective infective dose. Mice were immuned by different doses(10 mg·kg-1, 20 mg·kg-1, 40 mg·kg-1) of Astragalus polysaccharide(APS) and 0.9%NS , meanwhile the blank group was regarded as the control group. After mice were immuned, we detected serum IgG antibody levels by ELISA method,and took the twice effective dose of chlamydia trachomatis to attack the genital tract after a week. Then the mice genital shedding of epithelial cells were cultured at each interval 2d. After 10 days, we kil ed the mice to calculate spleen(thymus) index, and observed the pathological changes in the reproductive tract of the mice. [Results]Compared with the control group, spleen(thymus) index and serum IgG antibody levels of Astragalus polysaccharide group are significantly higher. The results of vaginal exfoliated cells from Ct training show that, Ct positive rate of Astragalus polysaccharide group is significantly reduced, the number of inclusion bodies is also significantly decreased. And with the increasing concentration of Astragalus polysaccharide, the protective effect is more obvious. The NS group has no significant difference from the control group in al indicators. [Conclusions]Astragalus polysaccharide can induce immune protection on Ct genital tract attacked mice, and in the concentration range, with the increase of the concentration, the protection effect is better.
ABSTRACT
Pointing to the contradiction features existent in teaching of clinical practice in the beginning stage of establishing affiliated hospital of university,it primarily discusses the management method in teaching of clinical practice,which gets first achievements after 3-year trial.
ABSTRACT
Objective To study the application of problem-based learning in combination with simulating teaching in clinical probation of gynecology and obstetrics. Methods The patten of problem-based learning in combination with simulating teaching was applied to experimental group,and the traditional teaching pattern to control group. The teaching effects were evaluated by evaluation of teacher,questionnaire after class and examination. Results Satisfaction ratio of experimental group was significantly higher than that of control group in questionnaire after class. The fine ratio of experimental group was significantly higher than that of control group in written history and case analysis; but there was no significance in excellence ratio and pass ratio. There was no significance in pass ratio ,fine ratio and excellence ratio of finals between them. Conclusion The application of problem-based learning in combination with simulating teaching in clinical probation of gynecology and obstetrics can develop students'ability to practice and improve the quality of class teaching.
