Objective To explore the distributions of genotypes of HPV infection in CIN and cervical carcinoma. Methods Cervical exfoliated cells were collected from 365 patients with abnormal cervical histology , and subjected to genotyping assay. Results The most prevalent HPV types were 16, 18,52, 58 and 33. The prevalence ratio of HPV 33,52,58 was signi cantly lower in squamous cell carcinoma. Multiple infections decreased from CIN II/III to cervical cancer. Conclusion Besides HPV 16/18, the 52/58/33 subtypes are also important in the development of cervical cancer.

Objective: To investigate the effect of occupational exposure on job burnout in nurses, and to analyze the mediating effect of negative emotion between occupational exposure and job burnout and the regulatory effect of supervisor support on occupational exposure and negative emotion. Methods: From September to December, 2015, simple random sampling was used to select 543 nurses from six tertiary hospitals in Zhejiang Province, China. The questionnaires consisted of occupational exposure risk questionnaire, negative emotion questionnaire, supervisor support questionnaire, and job burnout questionnaire. Results: The total score of occupational exposure risk in nurses was 11.43±7.19; the score of emotional exhaustion was 3.19±1.24, the score of low sense of personal accomplishment was 3.02±1.21, and the score of sense of working indifference was 2.24±1.06. There were significant differences in occupational exposure score between nurses with different sexes (t=2.61, P<0.01) and working years (F=4.49, P<0.01) . There were significant differences in the scores of emotional exhaustion and low sense of personal accomplishment in nurses with different sexes (t=5.25, P<0.001) and working years (t=-3.48, P<0.01) . Occupational exposure had positive effects on negative emotion (β=0.41, P<0.05) , emotional exhaustion (β=0.47, P<0.05) , sense of working indifference (β=0.42, P<0.05) , and low sense of personal accomplishment (β=0.17, P<0.05) . Negative emotion had a partial mediating effect between occupational exposure and emotional exhaustion (total effect size 30.5%, P<0.05) and between occupational exposure and sense of working indifference (total effect size 37.1%, P<0.05) . Negative emotion had a complete mediating effect between occupational exposure and low sense of personal accomplishment (β=0.08, P>0.05) . Supervisor support negatively regulate the effects of occupational exposure and negative emotion (F=21.73, P<0.001) . Conclusion In nurses, occupational exposure has a direct positive effect on job burnout and indirectly influences job burnout via negative emotion. Supervisor support can reduce the negative impact of occupational exposure on negative emotion.

Objective To investigate the clinical features, pathological characteristics and prognostic factors of the ma-lignant ovarian germ cell tumor. Methods There was a retrospective analysis about 31 patients of malignant ovarian germ cell tumor from Jan 2006 to Dec 2011,while clinic and pathological factors were analyzed,and the related litera-ture was prognostic analyzed. Results Nine cases were ovarian teratoma with malignant change in 31 patients. 7 cases were ovarian immature teratoma, 6 cases were ovarian dysgerminoma, 5 cases were yolk sac tumor, 3 cases were em-bryonal carcinoma, 1 patient was ovarian mixed yolk sac tumor and embryonal carcinoma. Multivariate survival analysis showed that operation pathological staging and pathological types were independent prognostic factors affecting overall survival rate for patients (P=0.018 and P=0.021). A variety of different pathological types of malignant ovarian germ cell tumor survival rate, the difference was statistically significant (P=0.049). Conclusion Operation and pathology of malignant ovarian germ cell tumor staging more late, the survival rate of the patients is low. Prognosis of ovarian malig-nant germ cell tumors of different pathological types is different.

Objective? To explore the effects of prone position combined with reverse Trendelenburg position on improving hypoxemia and respiratory mechanics of acute respiratory distress syndrome (ARDS) patients. Methods? From January 2017 to December 2017, we selected ARDS inpatients in Intensive Care Unit at Affiliated Hospital of Shaoxing University as subjects by convenience sampling. The total of 20 patients were divided into group A and group B with the method of random number table. Patients of group A adopted prone position for two hours firstly, and then they adopted prone position combined with reverse Trendelenburg position for six hours. Patients of group B adopted prone position combined with reverse Trendelenburg position for two hours firstly, and then they adopted prone position for six hours. During treatment, we assessed the function of pulmonary ventilation and respiratory mechanics of patients. Results? There were statistical differences in different time, different groups and interaction between time and groups among ARDS patients between two groups (P＜ 0.01). Two hours after intervention, the oxygenation index of group B was higher than that of group A with no statistical difference (P＞0.05). One, five and eight hours after intervention, the oxygenation indexes of group A were higher than those of group B with statistical differences (P＜ 0.05). The oxygenation index of group A increased with time, and that of group B increased two hours after intervention and then reduced. There was no statistical difference in the respiratory mechanics of patients between two groups (P＞ 0.05). Conclusions? Prone position combined with reverse Trendelenburg position can improve the oxygenation of ARDS patients.

Objective To explore the correlation between the occupational coping self-efficacy and family-work enrichment. Methods In June 2017, totally 58 male nurses were recruited by convenient sampling method and investigated by the Occupational Coping Self-efficacy Scale for nurses and Work-family Enrichment Questionnaire. Pearson correlation analysis and hierarchical regression analysis were used to analyze the effect of family-work enrichment on male nurses' professional coping self-efficacy. Results The mean scores of male nurses' occupational coping self-efficacy and work-family enrichment were (32.81±4.15) and (21.50±3.73) respectively. Pearson correlation analysis showed that each dimension of work-family enrichment was significantly correlated to occupational coping self-efficacy (r=0.592,P< 0.001). Hierarchical regression analysis showed that all the dimensions of work-family enrichment could explain 33.5% of the variance of male nurses' occupational coping self-efficacy. Conclusions Male nurses' occupational coping self-efficacy is closely related to family-work enrichment.

Objective To investigate the clinical, radiological and pathological characteristics, treatment and prognosis of pulmonary benign metastasizing leiomyoma (PBML). Methods The clinical and image data of 6 patients with PBML confirmed by pathology from October 2012 to December 2016 were retrospectively analyzed, and the related literature was reviewed. Results Six cases were female, age was from 32 to 55 (43.80 ± 7.17) years. Two cases were found by physical examination, 2 cases had chest distress and asthma, 1 case had chest pain, and 1 case had hemoptysis. Pulmonary abnormalities were detected between 1 month and 15 years after uterine myomectomy. Chest CT showed that multiple lung nodules or masses were observed in 5 patients, among which random distribution was in 3 cases, diffuse military nodule pattern was in 2 cases, and single mass combined with primary lung adenocarcinoma was in 1 case. Fluorine-18-fluorodeoxyglucose positron emission tomography/CT (18F- FDG PET/CT) of one patient showed no obvious uptake of the maximum standardized uptake value. All patients were confirmed histologically with CT guided lung biopsy (2 cases), thoracoscopic lung biopsy (2 cases), and thoracoscopic lobectomy with wedge resection (2 cases). Tumor cells revealed the characteristics of smooth muscle cell differentiation. Immunohistochemistry showed strong positive express of Desmin, SMA smooth muscle specific markers, estrogen receptor and progesterone receptor. Three patients were treated with oral tamoxifen anti estrogen therapy with follow-up from 5 months to 5 years. Four cases had a good prognosis, and 2 cases were lost in follow-up. Conclusions PBML is a rare disease that is prone to occur in women of childbearing age. The clinical symptoms are atypical. Imaging examination and pathology are necessary for diagnosis. Surgery combined with endocrine therapy is effective.

ObjectiveTo explore the clinical efficacy of compound Wufengcao liquid （CWL） on tuberculous ulcer and the influence on macrophage polarization. Method① Clinical experiment： A total of 145 patients with tuberculous ulcer who were treated in Nanjing Integrated Traditional Chinese and Western Medicine Hospital were randomized into observation group， control group Ⅰ， and control group Ⅱ according to the random number table method. In addition to the basic anti-tuberculosis chemotherapy， CWL， Kangfuxin liquid， and isoniazid solution （local external application） were respectively used in the observation group， control group Ⅰ， and control group Ⅱ. The treatment lasted 4 weeks for each group. The total effective rate in wound healing， traditional Chinese medicine（TCM） syndrome score， and histopathological morphology of wound were observed and the expression of inducible nitric oxide synthase （iNOS） and arginase-1 （Arg-1） in wound tissue was measured. ② Cell experiment： RAW264.7 cells were cultured in DMEM （10% fetal bovine serum， 1% double-antibody solution） in a cell incubator （37 °C， 5% CO₂）. Phorbol 12-myristate 13-acetate （PMA） was used to induce the differentiation of RAW264.7 cells into macrophages. Lipopolysaccharide （LPS） was employed to stimulate polarization of macrophages into M1 type and interleukin-4 （IL-4） to induce the polarization into M2 type. Kangfuxin solution， isoniazid solution， and CWL were respectively applied to the above cell model for 36 h. The cell supernatant was collected and centrifuged. Western blot was used to detect the protein expression of tumor necrosis factor-α （TNF-α）， transforming growth factor-β （TGF-β）， iNOS， and Arg-1， and flow cytometry （FCM） to detect the expression of CD86 and CD206. Result①Clinical experiment： The total effective rate in the CWL group ［98.0% （48/49）］ was higher than that in the control group Ⅰ ［87.5% （42/48）， χ²=3.962， P<0.05］ and control group Ⅱ ［83.3% （40/48）， χ²=6.162， P<0.05］. After 28 days of treatment， compared with control group Ⅰ and control group Ⅱ， CWL decreased the TCM syndrome score （P<0.05） and obviously improved the histopathological morphology of the wound. Immunohistochemistry results showed that the iNOS expression in local focus tissue was lower （P<0.05） and the expression of Arg-1 was higher （P<0.05， P<0.01） in the CWL group than in the control group Ⅰ and control group Ⅱ after 28 days of treatment. ② Cell experiment： Western blot assay showed that the expression of iNOS and TNF-α in LPS group increased compared with that in the M0 group （P<0.01） and the expression in the LPS+ isoniazid group， LPS+ Kangfuxin group， and LPS+CWL group was lower than that in the LPS group （P<0.05）. The expression of iNOS in LPS+Kangfuxin group and LPS+ CWL group was lower than that in the LPS+isoniazid group （P<0.05， P<0.01）， and the expression of TNF-α in LPS+ CWL group was lower than that in LPS+isoniazid group （P<0.01）. The expression of TNF-α in LPS+ CWL group decreased compared with that in the LPS+ Kangfuxin group （P<0.05）. The expression of Arg-1 and TGF-β in IL-4 group was higher than that in the M0 group （P<0.01）， and the expression in the IL-4+isoniazid group， IL-4+Kangfuxin group， and IL-4+ CWL group was higher than that in the IL-4 group （P<0.05）. The expression of Arg-1 and TGF-β in the IL-4+ Kangfuxin group and IL-4+CWL group was higher than that in the IL-4+isoniazid group （P<0.05， P<0.01）， and the expression was higher in the IL-4+CWL group than in the IL-4+Kangfuxin group （P<0.05， P<0.01）. The FCM result showed that the expression of CD86 and CD206 in LPS group and IL-4 group was higher than that in M0 group （P<0.01）. CD86 expression in LPS+isoniazid group， LPS+ Kangfuxin group， and LPS+CWL group was lower than that in the LPS group （P<0.01）. The expression of CD86 in LPS+Kangfuxin group and LPS+ CWL group increased compared with that in the LPS+isoniazid group （P<0.01）， and the expression was higher in the LPS+ CWL group than in the LPS+Kangfuxin group （P<0.01）. CD206 expression in IL-4+ isoniazid group， IL-4+Kangfuxin liquor group， and IL-4+ CWL group was increased compared with that in the IL-4 group （P<0.01）. CD206 expression in IL-4+Kangfuxin liquid group and IL-4+ CWL group was decreased compared with that in the IL-4+isoniazid group （P<0.01）. CD206 expression in IL-4+CWL group was lower than that in the IL-4+ Kangfuxin group （P<0.05）. ConclusionCWL can promote the healing of tuberculous ulcers， and the mechanism is that it inhibits the expression of iNOS， TNF-α， and CD86 and promotes the expression of Arg-1， TGF-β， and CD206， thereby regulating M1/M2 polarization balance.
