ABSTRACT
Objective To study the treatment effect of joint nitric acid imidazole and itraconazole on recurrent candida vaginitis.Methods 200 confirmed cases of patients with recurrent candida vaginitis in our hospital during October 2014 to June 2015 were selected and divided into research group and the control group with random indicator method,with 100 cases in each group.The control group were treated by nitric acid imidazole vaginal soft capsule,with vaginal drug delivery,which shoud put suppository in vaginal depths after washing,for one times a night and one soft capsule every time,and a week was a period of treatment.The patients in the research group received basis treatment of the control group adding itraconazole capsules(200mg per day,oral).8 weeks after treatment,the patients in this process were reviewed to analyzed clinical efficacy and adverse reactions occured.Results The total effective rate of the research group was 98%,which of the control group was 73%,the difference was statistically significant(χ2 =25.21,P 0.05 ).Conclusion The curative effect of itraconazole joint miconazole nitratet to recurrent monilial vaginitis is superior to the use of miconazole nitrate alone, with less adverse reaction,and is easy to use.It is worth clinical application.
ABSTRACT
<p><b>OBJECTIVE</b>To establish HEK293 cell lines with stable expression of human parathyroid hormone (PTH) receptors.</p><p><b>METHODS</b>The purified gene fragments of PTH-related peptide receptor (PTHR) and its mutant form (DSEL) were cloned separately into pcDNA3.1(+) vector after digestion with EcoR I and Not I, and the resulted pcDNA3.1(+)-PTHR and pcDNA3.1(+)-DSEL plasmids were verified by restriction enzyme digestion and DNA sequencing. HEK293 cells were transfected with these plasmids and the expression of PTHR and DSEL in the cells were examined by RT-PCR and ELSIA.</p><p><b>RESULTS</b>Sequencing and restriction enzyme digestion analysis showed that PTHR and DSEL cDNAs were correctly cloned into pcDNA3.1(+)vector. After a 48-h transfection of HEK293 cells with the recombinant plasmids and G418 selection, the positive cell clones stably expressing the constructs were obtained, which showed expressions of PTHR and DSEL mRNAs detected by RT-PCR. These positive cells showed high levels of PLC and aAMP production in response to PTH stimulation.</p><p><b>CONCLUSION</b>The HEK293 cell lines with stable expression of PTH1R or DSEL gene established in this study provide useful cell models for studying the physiological functions of PTH peptides.</p>

BACKGROUND:Previous studies have confirmed the presence of bis-(3'-5')-cyclic dimeric guanosine monophosphate signaling pathway in Streptococcus mutans, which construct the streptococcus mutans gcp gene knockout strains. OBJECTIVE:To compare the gene expression differences between Streptococcus mutans wild strains and gcp mutant strains, and to screen the biofilm-related genes from them for the fol ow-up study. METHODS:The total RNA of two kinds of strains were extracted and stained with cy3 and cy5 respectively after reverse transcription. The gene chip was scanned after hybridization and the differential gene were obtained through the data analysis. The different expression genes were verified by real-time PCR. RESULTS AND CONCLUSION:Differential genes were mainly relative about glucose metabolism and biofilm formation. We selected two genes for real-time PCR verification. The PCR results were consistent with the microarray results. After Streptococcus mutans gcp gene knockout, the gene expressions of gcp mutant strains were upregulated and the gene expressions of phosphotransferase system were downregulated, this result suggested that two different genes were related with the c-di-GMP signal pathway downstream.
ABSTRACT
ObjectiveTo survey and analyze the changes of dental medical students' concerns before and after their internship in order to provide practical evidences for intern orientation and junior students education.MethodsAnonymous questionnaires were designed with single choice and multiple-choices and were accomplished by 175 dental medical students of different grades to investigate their' concerns before and after the clinical internship and choices for future employment.Results 47% freshmen,43% junior,45% graduates were willing to work in dental restoration field,30%sophomore and 39% senior were willing to work in orthodontics field.Before the internship,the most concem of 97% students was the teaching quality of the practice hospital; 67% students worried that patients may unsatisfy with the treatment.After the internship,the quality of the practice hospital was considered most important by 79% students; 51% students worried that internship may influence the postgraduate entrance exam.ConclusionTeachers should strengthen their self-cultivation and cope with the key concerns before the practice based on the investigation and survey after the practice.Meanwhile teacher should provide employment guidance for students based on students' interests and practice skill ability,encourage them to broaden their horizon and pay attention to the long-term interests in an aim to pave the way for future employment.
ABSTRACT
BACKGROUND: Heal-all oral biofilm is a material utilized in repairing oral mucosa and soft tissues defects and characterized by degradation, easily preparation, long preserved duration, convenient transportation and good ossification, which has been widely used in dental implant as guided bone regeneration materials.OBJECTIVE: To check the clinical effective of Heal-all oral biofllm on guided bone regeneration in dental implant.METHODS: A total of 72 patients with bone defects in the implantation area were selected as subjects, who were divided into control group and experimental group at random. Bone defects around implants were repaired by guided bone regeneration technique with BME-10X medical collagen membrane and Heal-all oral biofilm respectively. X-ray and clinical examination were taken at 1 and 3 months after implantation. The amount of new.formed bone tissue was evaluated when stage Ⅱ operation was performed.RESULTS AND CONCLUSION: In stage Ⅱ operation, osseointegration was formed between implants and bone tissue in all 72 patients. The average rate of bone formation was 92% in the experimental group while 91% in the control group. All implants were successfully repaired with implant denture. Occlusal function was restored successfully with all 72 implants during the follow-up period of 3-24 months after restoration. As an alternative option of BME-10X medical collagen membrane, Heal-all oral biofilm can be used in guided bone formation clinically.
