0.05).In the 35 patient who had unitary incontinence before the operation,the symptom disappeared in 6(17.1%) patients,and deteriorated in 2(5.7%).While in the 38 patients without urinary incontinence before the operation,9(23.7%) showed the symptom postoperation.Totally,urinary incontinence was developed in 11 patients after the operation.Conclusions The patients with moderate-to-severe pelvic organ prolapse treated by traditional surgical procedures have a low rate of objective cure and a high rate of recurrent cystocele.It is important to repair the anterior pelvic floor during the operation.And the surgeons should be alert to the possibility of urinary incontinence.

Objective To investigate the effect of comprehensive intervention led by nursing staffers on the drug compliance in patients with hepatitis B virus-related hepatocellular carcinoma (HCC) after receiving transcatheter arterial chemoembolization (TACE) treatment.Methods By using random sampling method,a total of 96 patients with hepatitis B virus-associated HCC,who had been treated with TACE and had taken nucleotide analogue drug for one month in the interventional department of a certain grade Ⅲ tumor hospital,were enrolled in this study.Under the premise of informed consent,comprehensive intervention,which was led by nursing staffers and was participated by both doctors and nurses,was conducted.Results After comprehensive intervention,the average score of drug compliance was (93.670±6.046) points,while the pre-intervention average score of drug compliance was (82.040±10.024) points,the difference between the two was statistically significant (P＜0.05).The ratio of patients who showed good drug compliance changed from pre-intervention 62.4％ to post-prevention 97.8％(P＜0.05).The post-prevention of patients,whose hepatitis B virus deoxyribonucleic acid (HBVDNA) level was within the normal range,was 45.16％,which was highcr than the pre-intervention ratio of 15.05％,the difference between the two was statistically significant (P＜0.05).Conclusion The comprehensive intervention led by nursing staffers can effectively improve the drug compliance in patients with hepatitis B virus-associated HCC after receiving TACE,and can reliably control serum HBVDNA level as well.

Objective: To construct the third generation chimeric antigen receptor based on a novel humanized anti-HER2 H1-2 scFv, and to investigate the specific cytotoxicity of H1-2 CAR modified T lymphocytes(CAR-T) against HER2⁺ tumor cells. Method: The expression cassette of the third generation CAR gene and anti-HER2 H1-2 scFv were constructed and cloned into lentivirus transfer plasmid, and then the third generation H1-2 CAR was transduced into human T lymphocytes using lentivirus.Enzyme linked immunosorbent assay was used to detect the expression of cytokines IL2, and LDH release assay was used to detect the cytotoxic effect of the H1-2 CAR-T.Finally, NOD/SCID mice and HER2⁺ breast cancer cell line SKBR3 were used to detect the anti-tumor effect of H1-2 CAR-T in vivo. Results: The third generation H1-2 CAR was successfully constructed.H1-2 CAR-T secreted high dose of IL2 after confrontation with HER2⁺ breast cancer cells.In vitro, the cytolytic rate of H1-2 CAR-T on high expression HER2⁺ tumor cells was significantly higher than that in low expression HER2 or non-expression HER2 tumor cells. At the efficacy to target ratio of 20, the cytolytic rate of H1-2 CAR-T against breast cancer cell SK-BR-3 could reach (90.1±2.8)%, while the cytolytic rate of H1-2 CAR-T against HER2^- breast cancer cell MDA-MB-231 was only (13.5±4.7)%. In the mouse xenograft tumor model, H1-2 CAR-T cells inhibited breast cancer growth in vivo.At the end of the experiments, the average tumor weight in the H1-2 CAR-T cell treatment group was (0.7±0.1) g, the non-transfected T cell therapeutic group was (1.2±0.2) g, and the PBS group was (1.2±0.2) g. There was significant difference between the H1-2 CAR-T therapeutic group and the non-transfected T cell therapeutic group (P<0.05). However, there was no significant difference between the non-transfected T cell therapeutic group and the PBS treatment group (P>0.05). Conclusion The HER2-sepcific H1-2 CAR-T cells specifically kill HER2 positive cells, and further studies on CAR-T cells for the treatment of HER2⁺ cancers are useful.

Objective:To evaluate the effects of comprehensive reform of clinical education on cultivating the clinical thinking ability of medical students in internal medicine.Methods:A total of 44 clinical interns on medicine rotation were included in this study and divided into experimental group and control group, and a series of measures for clinical teaching reform, which included undergraduate tutorial system, team-based learning (TBL) mode, combination of electronic medical record and handwritten medical record, as well as formative assessment, were applied to fully promote clinical thinking ability of medical students. SPSS 17.0 software was used to compare the scores of final academic tests of rotation and competition of medical record writing between the control and the experiment groups. Self-designed questionnaires on undergraduate tutors and clinical interns were applied to comprehensively evaluate the effects of this education reform.Results:Independent-sample t tests showed there were statistically significant difference ( P<0.01) in the scores of final academic tests of rotation and competition of medical record writing between the two groups, and the mean score of the experiment group was higher than that of the control group. Questionnaire survey showed that tutors and clinical interns both fully affirmed the positive effects of the education reform on cultivating clinical thinking ability of medical students in internal medicine. Conclusion:Application of comprehensive education reform in clinical teaching of internal medicine, which based on introduction of undergraduate tutorial system and TBL mode, could effectively promote the clinical thinking ability of medical students and the teaching quality.
