Objective To survey age of menarehe in Pudong district in Shanghai. Methods Data in this study were derived from 56 924 women at age of 20 -81 years in screening for cervical cancer between January 2007 and July 2008 in Pudong district. The age of menarche were recorded in a questionnaire. To investigate the trends in age at menarehe in different socioeconomic status, the subjects were divided into 12 groups in 5-year birth cohorts. The mean menarche age in each group was analyzed by analysis of variance(ANOVA). The percentage of menarche age at 10- 12 years and more than 18 years was analyzed by χ2 method. Results (1 ) The minimum age of menarcbe recorded is 10 years old, and the maximum is 28 years old, with average age of menarche at 15.7 years. In all groups, the smallest average age of menarcbe is 14. 6 years in 26 - 30 years old age group, while the biggest average age of menarche age is 16. 5 years in ＞ 75 years old group; The difference showed statistical significance (P ＜ 0. 01 ). (2) The percentages for participants with early menarehe age (10 - 12 years old) or late menarehe age (＞ 18-year-old menarche) were 1.82% (1034/56 924 ) and 5.20 % (2959/56 924 ) respectively. However, the maximum percentage for early menarche was recorded in 31 -35 years old group (4. 45% ,197/4431 ), only 0. 84% (10/1191 ) of participants in ＞75 years old group was classified as early menarebe. Meanwhile, the lowest percentage for late menarehe was 0. 38% (17/4431 ) in 31 - 35 years old group, and the highest percentage was 14. 70% (91/619) in ＞ 75 years old group. The changes in the percentages for early menarche or late menarche are significantly associated with age differences (P ＜ 0. 01 ). Conclusion The study suggested that the average of onset age of menarche in Pudong district has declined over the past decades in an age-based way, accompanied with the increase of the percentage for early menarche and the decrease of percentage for late menarehe.

Objective To understand the current situation of satisfaction and self-efficacy of nursing students in clinical practice and to explore the correlation between the two. Method A total of 120 nursing students in clinical practice were investigated using the general nursing student satisfaction scale and the general self-efficacy scale (GSES). Results The satisfaction score of nursing students was(151.89 ± 22.36)points and the score of nursing students self-efficacy was(29.06 ± 6.70)points.Nursing students self-efficacy was positively correlated with their job satisfaction (r=0.390,P＜0.01).Regression analysis showed that nursing students self-efficacy had a significant impact on job satisfaction (t=3.363,P＜0.01). Conclusion According to the characteristics of nursing students,clinical nursing education administrators should formulate and implement targeted interventions to deepen their love of nurses and improve their sense of self-efficacy,so as to enhance job satisfaction of nursing students.

Objective: To study the relationship between human herpes vi rus 6 (HHV-6) infection and oral squamors cell carcinoma. Methods: The serum anti-HHV-6 antibody titers from 16 cases of oral squamors cell carcinoma (OSCC) and 16 control subjects were detected by indirect immunofluores cence assay. HHV-6 DNA in peripheral blood mononuclear cells was amplified by P CR and the specificity was confirmed by Southern-blot hybridization with an int ernal probe oligonuclotide. An immunohistochemical staining was used to detect H HV-6 antigen in OSCC tissues. Results: Positive expression of s erum HHV-6 IgG antibody was found in all the cases of OSCC and in 12 of the 16 controls. Geometric mean titer of OSCC group and control group was 1∶118 and 1 ∶64 respectively (P

Objective: To construct a prediction model for preeclampsia (PE) risk in twin-pregnant women, so as to provide the basis for early screening and prevention of PE. Methods: A total of 467 twin-pregnant women who underwent prenatal examination and delivered at Huzhou Maternal and Child Health Hospital were selected. Sixty cases with preeclampsia (PE) were included in the case group, and 60 women without PE were included in the control group. General information, blood biochemical indicators and uterine artery resistance index (UtA-RI) were collected. A logistic regression model was used to screen predictive factors and establish a nomogram. The Bootstrap method was performed for the internal validation; the receiver operating characteristic (ROC) curve, calibration curve and decision curve analysis were employed to evaluate the discrimination, calibration and clinical utility of the nomogram, respectively. Results: In the case group, there were 47 individuals (78.33%) aged younger than 35 years, 21 individuals (35.00%) with pre-pregnancy body mass index (BMI) of 25 kg/m2 and above, and 33 individuals (55.00%) with in vitro fertilization. In the control group, there were 57 individuals (95.00%) aged younger than 35 years, 8 individuals (13.33%) with pre-pregnancy BMI of 25 kg/m2 and above, and 39 individuals (65.00%) with natural pregnancy. Multivariable logistic regression analysis identified age, pre-pregnancy BMI, method of conception, placental growth factor (PLGF) and UtA-RI as risk prediction factors for PE in twin-pregnant women. The established nomogram had an area under the ROC curve of 0.827 (95%CI: 0.755-0.899), a sensitivity of 0.767, a specificity of 0.733, a good discrimination and calibration, and a relatively high clinical net benefit. Conclusion The nomogram established by age, pre-pregnancy BMI, method of conception, PLGF and UtA-RI has a good predictive value for the risk of PE in twin-pregnant women.

Objective To evaluate the imaging methods for cardiovascular malformations in Williams syndrome(WS).Methods Thirteen cases of WS(7 males and 6 females)aged 10 months to 13 years were involved in this study.All patients underwent chest X-ray radiography,electrocardiography.echocardiography and physical examination.3 cases underwent electronic beam computed tomography (EBCT),cardiac catheterization and angiography were performed in 8 cases.Results Twelve patients were referred to our hespital for cardiac murmur and 1 cnse for cyanosis after birth.7 patients were found with "elfin-like"facial features.6 patients with pulmonary arterial stenosis.2 Cases with patent ductus arteriosus.2 case8 with 8evere pulmonary hypertension and 1 case with total endocardial cushion defect.Sudden death occurred in 2 patients during and after catlleterization.respectively. Conclusions Conventional angiography is the golden standard for the diagnosis of cardiovascular malformations in WS.Noninvnsive methods such as MSCT and MRI should be suggested because of the risk of sudden death in conventional angiography.

Objective To evaluate the imaging diagnosis of anomalous origin of coronary artery from the pulmonary artery(ACAPA).Methods A total of 11 cases with ACAPA were included in the present study.Chest films,echocardiography,cardioangiography,and electron beam computed tomography (EBCT) were employed as diagnostic modalities.Macroscopic anatomy at operation was referred. Results Ten cases were classified as anomalous origin of left coronary artery from the pulmonary artery(ALCAPA) and 1 case as anomalous origin of right coronary artery from the pulmonary artery(ARCAPA).They could not be diagnosed by chest films,but could be diagnosed by echocardiography in 3 cases,by EBCT in 1 case,and by cardioangiography in all cases.In ALCAPA,cardioangiography showed that the left coronary arteries arising from the posterior sinus or posterior wall of the pulmonary artery were perfused retrogradely via the collaterals from the dilated right coronary artery.In ARCAPA,the right coronary artery originated from the right sinus of the pulmonary artery.Gross anatomy at operation showed that the sites of the anomalous origins were the same as that of cardioangiography.Ischemic fibrosis of the anterior papillary muscles,mitral valve annulus enlargement,and prolapse of mitral valve,which led to mitral valve insufficiency,were found in 3 cases.Conclusion Chest film has limitation in the diagnosis and echocardiography should be further improved.Cardioangiography remains the “gold standard” of the preoperative diagnosis.
