Objective:To investigate the feature of depression in patients with Parkinson's disease(PD) and the related factors.Methods:Use Hamilton Depression Scale(HAMD) to measure the level of depression of 60 patients with PD.Functional state of the patients was evaluated by Motor Dysfunction Rating Scale for Parkinson's Disease(MDRSPD).Results:29 cases(48.3%) were identified to have depression,among whom 40% were of minor or moderate degree,8.3% were severe.The main manifestations of depression were anxiety/body,retardation,hopelessness and insomnia.Scores of hopelessness,retardation,and insomnia factor were significantly higher in the rigidity and tremor combining rigidity patients than those in tremor patients.The level of depression positively correlated with the duration of disease and degree of dysfunction due to PD,and it has no relation with age,sex,and education.Conclusions:The incidence of depression was higher in patients with PD.PD patients of different clinical types had different characteristics of depression.The rigidity type is more likely to get depression.The degrees are closely related to duration of disease and degree of dysfunetion.

Objective To investigate the change of adiponectin level with menopause status in women aged 40 to 65, and its relationship with androgen. Methods A cross-sectional study included woman (aged from 40 to 65) who were in hospital for routine check-up at the Sun Yat-sen Memorial Hospital from August to October in 2013. All subjects underwent laboratory examinations of adiponectin, sex hormone binding globulin (SHBG), dehydroepiandrosterone-sulfate (DHEA-S), total testosterone (TT), collected anthropometric measurements and then calculated free androgen index (FAI) and body mass index (BMI). According to their menstrual status, the subjects were divided into 4 groups: premenopausal group with 119 subjects, perimenopausal group with 60 subjects, early postmenopausal group with 62 subjects, late postmenopausal group with 64 subjects. Results (1) Adiponectin levels declined to its lowest level in menopausal transition and gradually becoming higher after menopause, which showed a U-shaped trajectory. When compared adiponectin levels in late postmenopausal group [(13 ± 5) mg/L] with those in perimenopausal [(8 ± 6) mg/L] or early postmenopausal group [(9 ± 6) mg/L], it all showed significantly difference (P<0.05). (2) Both the adiponectin levels were negatively correlated with waistline in the 4 groups (premenopausal group, r=-0.276;perimenopausal group, r=-0.334;early postmenopausal group, r=-0.211;late postmenopausal group, r=-0.218; all P<0.05). Levels of adiponectin were positively correlated with SHBG (r=0.536, P<0.05) and negatively with FAI (r=-0.363, P<0.05) in menopausal transition, while in late postmenopausal group, negatively correlated with level of DHEA-S (r=-0.450, P<0.05). When adjusted for age, BMI and waistline, the above correlations still exist. Conclusions Adiponectin levels declined to its lowest level in menopausal transition and gradually becoming higher after menopause, which showed a U-shaped trajectory during the sequential menopause status transition in middle aged women. Low level of adiponectin in menopausal transition is closely associated with the relative excess androgen occurred during this stage.

Objective To investigate the relationship between blood vessel invasion (BVI) and clinicopathologic features and prognosis in patients with gastric cancer,and analyze related factors affecting the prognosis of patients.Methods The clinicopathological data of 206 patients with gastric cancer who were admitted to the Nanjing Hospital Affiliated to Nanjing Medical University from January 2007 to December 2010 were retrospectively analyzed.The BVI of surgical tumor specimens in all patients was detected by immunohistochemical staininng.All the patients were followed up via outpatient examination and telephone interview up to March 2014.The count data were analyzed using the chi-square test.The survival curve was drawn by Kaplan-Meier method.The survival analysis and univariate analysis were done using the Log-rank test,and multivariate analysis was done using the COX regression model.Results The BVI rate of 206 patients was 27.67％ (57/206).The BVI rate of tumor tissues,tumor differentiation,perineural invasion,T stage,N stage and TNM stage in all patients with gastric cancer were compared,showing significant differences (x2=14.396,9.569,15.579,43.453,30.732,P ＜ 0.05).After operation,188 patients were followed up for 6.0-60.0 months (median,34.0 months),with the follow-up rate of 91.26％ (188/206).Among 188 patients with follow-up,the median survival time and 5-year cumulative survival rate in patients with BVI and with negative BVI were 32.4 months and 19.6％,40.7 months and 42.0％,respectively,with a significant difference in the survival of patients (x2 =9.364,P ＜ 0.05).The results of univariate analysis showed that the diameter of tumor,tumor differentiation,perineural invasion,BVI,T stage,N stage and TNM stage were factors affecting the prognosis of patients with gastric cancer (x2=9.241,17.486,11.243,9.364,27.666,216.745,49.887,P ＜ 0.05).The results of multivariate analysis showed that the diameter of tumormore than 5 cm,BVI,stage T4,stage N3 and stage Ⅲ were independent risk factors affecting the prognosis of patients with gastric cancer (HR =0.502,0.456,0.052,0.001,0.735; 95％ confidence interval:0.334-0.754,0.289-0.720,0.004-0.664,0.000-0.006,0.159-3.398,P ＜ 0.05).Conclusions BVI in patients with gastric cancer is associated with the progression of tumors.The diameter of tumor more than 5cm,BVI,stage T4,stage N3 and stage Ⅲ are independent risk factors affecting the prognosis of patients with gastric cancer,and BVI may be a predictor of poor prognosis of patients with gastric cancer.

Objective To analyze the risk factors of respiratory depression occurring during recovery period in patients after having undergone general anesthesia and laparoscopic operation.Methods A total of 374 patients after general anesthesia and laparoscopic surgery admitted to the First Affiliated Hospital of Wenzhou Medical University from June 2015 to June 2016 were enrolled, they were divided into with or without the incidence of respiratory depression two groups by whether or not respiratorydepression, with the incidence of respiratory depression group 52 cases, without the incidence of respiratory depression group 322 cases. The patients' gender, age, body mass index (BMI), operation time, anesthesia maintenance mode, artificial airway mode, operative type and medication used in operation, intra-operative hypotension presence or absence, and type of operation were recorded. Univariate and multivariate logistic regression analyses were used to evaluate the risk factors of respiratory depression occurring in the recovery period after general anesthesia; receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of age, intraoperative medication, and age combine with intraoperative medication respectively in the occurrence of respiratory depression during recovery period after general anesthesia and lapatoscopic operation.Results Univariate analyses showed that there were no statistical significant differences in gender, BMI, operation time, anesthesia maintenance mode, artificial airway mode, intra-operative hypotension presence or absence, type of operation, etc. compared between patients with and without the incidence of respiratory depression groups (allP > 0.05); while the differences were statistically significant in age and drug used in the operation (dezocine, flurbiprofen, dexmedetomidine or dezocine combined with dexmedetomidine, allP < 0.05). Multivariate analyses showed that age and medication used in operation were the independent risk factors for the occurrence of respiratory depression during the anesthesia recovery stage (P values being 0.000, 0.002 respectively). ROC curve showed that age, intra-operative medication and age combine with intraoperative medication respectively had certain predictive value for the occurrence of respiratory depression during the recovery period after general anesthesia and laparoscopic surgery, the area under the ROC curve (AUC) of age combine with intraoperative medicationfor prediction of occurrence of respiratory depression during recovery period after anesthesia and laparoscopic surgery was significantly larger than that of single age or single intraoperative medication (0.826 vs. 0.668, 0.750,P < 0.01), 95% confidence interval (95%CI) of age, intraoperative medication and age combined with intraoperative medication were 0.598-0.738, 0.670-0.830, 0.764-0.888, the sensitivity, specificity and accuracy rate of age combine with intraoperative medication were 53.8%, 94.4% and 88.8%, respectively.Conclusion Elderly patients undergoing general anesthesia and laparoscopic operation and dezocine, dexmedetomidine or dezocine combined with dexmedetomidine being applied in the laparoscopic operation are more easily associated with incidence of respiratory depression during recovery period of anesthesia.

Objective:To investigate the correlation between amide proton transfer-weighted (APTw) values and Ki-67 labeling index of cervical squamous cell carcinoma.Methods:From October 2017 to December 2018, 24 patients with cervical squamous cell carcinoma [International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ-Ⅲ] were prospectively enrolled in Peking Union Medical College Hospital and underwent pelvic morphological MRI on a 3.0 T MR scanner, including three-dimensional turbo-spin-echo APTw imaging and DWI. The maximum diameters of the lesions, APTw values and ADC values on the slice with the maximum diameter of the lesion were independently measured by two radiologists. The ICC was computed to evaluate the inter-observer consistency. Ki-67 immunohistochemical expression status was assessed by one pathologist. The Pearson correlation analysis was performed between the APTw values, maximum diameters, ADC values and Ki-67 labeling index.Results:The APTw values of cervical squamous cell carcinoma were (2.9±0.5)%. Inter-observer ICC was 0.972 (95%CI 0.937-0.988). The APTw values were positively moderately correlated with Ki-67 labeling index [(61.9±18.7)%, r=0.532, P=0.008]. The maximum diameters of the lesions were (28.7±10.6) mm. The mean ADC values were (0.998±0.217)×10 -3 mm 2/s. No correlations were found between maximum diameters, ADC values and Ki-67 labeling index ( r=0.038, P=0.859; r=0.238, P=0.263). Conclusion:APTw values can partially reveal the proliferation status of cervical squamous cell carcinoma.
