Background Anxiety and depression are common perinatal mental health issues that often occur together and can have serious negative effects on both maternal and infant health. Objective To examine the relationships between lifestyle factors and comorbid anxiety and depression (CAD) among pregnant women in Shanghai. Methods The study estimated the prevalence of CAD during the first, second, and third trimesters of pregnancy using the Self-rating Anxiety Scale (SAS) and Center for Epidemiological Studies-Depression (CES-D) based on data from the China National Birth Cohort (CNBC) embryonic-derived diseases with assisted reproductive technology (ART) sub-cohort. Information on demographics, sleep status, nutritional intake, and exercise during each trimester was collected through self-made questionnaires, the Pittsburgh Sleep Quality Index (PSQI), and the Food Frequency Questionnaire (FFQ). Lifestyle factors (such as sleep status, nutritional intake, and exercise during each trimester) were analyzed using logistic regression and generalized linear mixed models (GLMM) to determine their impacts on the prevalence of CAD (yes or no) among pregnant women. Results A total of 2876 pregnant women were included in this study. The prevalence of CAD was 10.6% (305), 3.6% (103), and 5.5% (159) in the first, second, and third trimesters of pregnancy, respectively. The logistic regression analysis revealed that poor sleep quality throughout the entire pregnancy were statistically associated with an increased prevalence of CAD, and the odds ratios (OR) with 95% confidence intervals (CI) were 2.817 (1.845, 4.301), 2.840 (1.855, 4.347), and 9.316 (5.835, 14.876) for the first, second, and third trimesters, respectively, when compared to good sleep quality. Additionally, compared to an intake frequency of 7 times per week, the frequency of egg intake ≤3 times per week in the first trimester (OR=2.025, 95%CI: 1.197, 3.425) and the frequency of egg intake of 4–6 times per week (OR=1.896, 95%CI: 1.117, 3.216) or ≤3 times per week (OR=1.906, 95%CI: 1.082, 3.357) in the third trimester were associated with an increased risk of CAD (P<0.05). Moreover, when compared to a frequency of exercise >3 times per week, never or almost never exercising in the second trimester (OR=2.218, 95%CI: 1.220, 4.035) was associated with an increased risk of CAD (P<0.05). The GLMM analysis also demonstrated a significant association between poor sleep quality, lower exercise frequency, or lower intake frequency of vegetables, eggs, or milk and an increased risk of CAD (P<0.05). Conclusion The prevalence of CAD among pregnant women in Shanghai follows a U-shaped distribution, with the highest rate occurring in early pregnancy and the lowest rate in mid-pregnancy. Factors such as poor sleep quality, inadequate intake of vegetables, eggs, or milk, and lack of exercise during pregnancy may increase the risk of CAD. Implementing lifestyle interventions during pregnancy could potentially reduce the risk of mental health problems and improve the overall health of both mothers and babies.

OBJECTIVE To observe the changes of cardiac function,local inflammation level and macrophage M2 polarization in mice with acute myocardial infarction(AMI after electroacupuncture preconditioning at the Neiguan point,and to explore the possible mechanisms from the perspective of regulating the DNA-PK/Rictor/Myc signaling pathway.METHODS Male C57BL/6J mice were randomly divided into sham group,model group and electroacupuncture group,with 10 mice in each group.The electroacupuncture group received bilateral electroacupuncture interventions at the Neiguan points,sparse-dense wave,2/15 Hz,1 mA,20 min/time,once a day for 3 consecutive days,and AMI models were performed 0.5 h after the electroacupuncture interventions.The myocardial ischemia model was prepared by ligating the left anterior descending branch.Echocardiography was used to detect cardiac ejection frac-tion(EF and fractional shortening(FS to evaluate cardiac function;HE and TUNEL staining were used to observe the pathological morphology of myocardium and apoptosis of cardiomyocytes,and immunohistochemistry and ELISA were used to detect IL-1β,TNF-α and NLRP3 in infarcted myocardium and peripheral blood to evaluate the level of inflammation;flow cytometry was used to detect cardiac macrophage polarization status,and Western blot method to detect the protein expression levels of DNA-PK,p-DNA-PK,Rictor and Myc in infarcted myocardium.RESULTS Compared with the sham group,the model group showed significantly lower EF and FS(P<0.000 1,significant inflammatory cell infiltration,significantly higher cardiomyocyte apoptotic index(P<0.001,up-regulated expression of IL-1β,NLRP3 and TNF-α in the myocardium and serum(P<0.01,P<0.001,a significant increase in the percentage of macrophages(P<0.001,a decrease in the percentage of cardiac M2-type macrophages(P<0.000 1,and a significant decrease in the expression levels of p-DNA-PK,Rictor and Myc proteins in myocardium(P<0.05,P<0.000 1.Compared with the model group,EF and FS were significantly higher in the electroacupuncture group(P<0.000 1,inflammatory cell infiltration was re-duced,cardiomyocyte apoptotic index was decreased(P<0.01,and the expression of IL-1β,NLRP3 and TNF-α was down-regula-ted in myocardium and serum(P<0.05,P<0.01,P<0.001;the macrophage percentage was decreased(P<0.05,cardiac M2-type macrophage percentage was increased(P<0.01,and p-DNA-PK,Rictor and Myc protein expression was enhanced in myocardium(P<0.05,P<0.01,P<0.000 1.CONCLUSION Electroacupuncture preconditioning may promote macrophage M2 polarization,attenuate local inflammation,and reduce cardiomyocyte apoptosis by modulating the DNA-PK/Rictor/Myc signaling pathway,thus im-proving cardiac function and achieving myocardial protective effects.

Objective To investigate the diagnostic potential of low-dose computed tomography angiography(CTA)and global biomimetic three-dimensional model reconstruction technology in patients with arterial erectile dysfunction(ED).Methods A total of 136 patients with ED were selected.Digital subtraction angiography(DSA)was performed on all patients as per their treatment requirements and conditions,following ultrasound and CTA examination,and 75 patients finally completed DSA examination.All patients with International Index for Erectile Function(IIEF5)score ranged from 1 to 20.All patients received immediate ultrasound monitoring after injection of alprostadil 10 μg and underwent CTA examination.DSA was conducted at a minimum interval of 72 h.The global biomimetic three-dimensional model tool was used to reconstruct the CTA data and evaluate the stenosis of the pudendal vessels.The diagnostic efficacy of CTA examination,ultrasound and DSA examination were compared and calculated.Results A total of 1 632 vessels were evaluated in 136 patients,including 155 stenoses.DSA was performed in 75 patients.A total of 900 vessels were evaluated,of which 88 were stenoses.Compared with the results of CTA,ultrasound and DSA,the average stenosis scores of all measured vessels were not statistically significant(P＜0.05).The correlation between CTA and ultrasound(r2=0.939 9,P＜0.000 1)and DSA(r2=0.944 0,P＜0.000 1)in the evaluation of vascular stenosis were good,and the diagnostic consistency was consistent.Conclusion Low-dose CTA and global biomimetic three-dimensional model reconstruction technology can effectively diagnose pudendal artery stenosis,and can perform all-round reconstruction observation,which is worthy of further clinical application.

Objective:To develop a risk prediction model for postoperative catheter-associated urinary tract infection (CAUTI) in patients with gynecologic malignancies, so as to provide a reference for the prevention of CAUTI.Methods:From January to June 2020, convenience sampling was adopted to select postoperative 800 patients with gynecologic malignancies and indwelling urinary catheters in Zhejiang Cancer Hospital as the research object. The patients were divided into derivation samples (derivation group) and validation samples (validation group) according to the ratio of 3∶1 by random number table method. In the derivation group of 600 cases, the predictive factors were analyzed by binomial Logistic regression analysis and the risk prediction model was developed. In the validation group of 200 cases, the receiver operating characteristic curve was used to evaluate the prediction performance of the model.Results:Binomial Logistic regression analysis showed that age ≥ 60 years old, intraoperative urinary tract injury, postoperative bladder irrigation, and indwelling catheter for more than 7 days were risk factors for CAUTI, and the difference was statistical ( P<0.05) . Model evaluation showed that the area under the receiver operating characteristic curve of the validation group was 0.79 with a statistical difference [95% CI (0.72, 0.87) , P<0.01], and the sensitivity, specificity and Youden index were 71.8%, 78.3% and 50.1% respectively. Conclusions:The prediction performance of the model is good, which helps medical and nursing staff to monitor high-risk patients and reduce the occurrence of CAUTI.

Parkinson′s disease (PD) is a common neurodegenerative disease. Its main pathological feature is the progressive loss of substantia nigra and other catecholaminergic neurons containing neuromelanin (NM). Therefore, NM may be closely related to the pathogenesis of PD. The content of NM can be detected by NM magnetic sensitive sequence imaging, and then it can be applied to the study of the neuropathological mechanism of NM and PD. This paper focuses on the physiological significance of NM, its role in the pathogenesis of PD and the prospect of NM as a biomarker to assist diagnosis and disease monitoring of PD.

Spinocerebellar ataxia type 2 (SCA2) is an autosomal dominant degenerative disease. The main clinical manifestation of SCA2 is progressive cerebellar syndrome, but a wide range of extracerebellar and non-motor symptoms can be observed clinically. The non-motor symptoms and extra-cerebellar signs in SCA2 patients are reviewed to provide a better understanding in cognition, diagnosis and treatment of the disease.

Objective? To investigate the effectiveness of family-based telenursing on the management of pressure sores in discharged emergency patients with pressure sores. Methods? Using the convenient sampling method, we selected 100 dyads of pressure sores patients along with their main home caregiver (one caregiver per patient). The patients were admitted to the Emergency Department of Beijing Anzhen Hospital from January to December 2017, who were randomly divided into the observation group and control group (50 dyads for each group). After the discharge of the control group, routine follow-ups were administered to guide the care of pressure sores. After the discharge of the observation group, the family-based telenursing was implemented for pressure sore management. The differences between the two groups of patients at the time of discharge, 2 months after discharge, nursing knowledge of pressure sore disease, differences in home care ability, and satisfaction with pressure sores management were analyzed. Results? There were no significant differences between the two groups at the time of discharge (P＞ 0.05). After 2 months of discharge, the severity of pressure sores, risk score, and recurrence rate of pressure sores in the observation group were lower than those in the control group, and the differences were statistically significant (P＜ 0.05). The caregiver's knowledge of pressure sores in the observation group was better than the control group, and the difference was statistically significant (P＜0.05). The total scores and the dimension scores of the family nursing evaluation in the observation group were higher than those in the control group, and the differences were statistically significant (P＜0.05). Patients and caregivers in the observation group were more satisfied with the nursing methods than the control group (P＜0.05). Conclusions? Family-based telenursing can improve the knowledge of pressure sores, the nursing ability,and effectively manage pressure sores.

Objective To investigate the cognition and attitude about human papillomavirus (HPV) and HPV vaccines among nurses, so as to provide a certain basis for the popularization of HPV vaccine. Methods A self-designed questionnaire was used to survey the cognition and attitude about HPV and its vaccine among nurses in Zhejiang Cancer Hospital by a professional platform named "Wenjuanxing" from August to September 2017. A total of 206 questionnaires were collected.Results Among 206 nurses, 98.5％ of the nurses had heard of HPV, only 14.1％ knew HPV could spread through touching and 41.3％ knew that HPV infection can be self subsided. 90.3％ of the nurses had heard of HPV vaccine. 78.6％ of the nurses would like to take HPV vaccine, and 70.2％ of the nurses agreed their daughters to take HPV vaccine. Over 60％ nurses worried about the safety and efficacy of HPV vaccine.Conclusions Nurses have some knowledge about HPV and HPV vaccine, but it is not comprehensive enough. The government should strengthen the publicity of knowledge about HPV and HPV vaccine.

Objective To investigate the correlation between serum level of insulin growth factor 1 (IGF-1) and the degree of liver fibrosis in patients with chronic hepatitis C (CHC) complicated to type 2 diabetes mellitus (T2DM). Methods The cases were divided into CHC with T2DM (39 cases), CHC (96 cases), T2DM (60 cases), and healthy control (60 cases) groups. Their human data were collected and the fasting blood glucose, insulin and insulin-like growth factor-1 levels were detected, and the insulin resistance index ( HOMA-IR) wwer calculated. The serum levels of alanine transaminase ( ALT) , aspartate transaminase ( AST) , hepatitis C virus ( HCV) RNA load and HCV genotypes were detected simultaneously in patients with hepatitis C, and liver stiffness were measured ( LSM) by transient elastography ( TE) and aspartate aminotransferase-to-platelet ratio index ( APRI) score was performed. Results ⑴ There was no significant difference between CHC with T2DM group and CHC group in diabetes family history(P>0. 05), but two groups were significantly lower than that of T2DM group (P<0. 05). ⑵The levels of fasting insu-lin (FI) and HOMA-IR in CHC with T2DM group and T2DM group were significantly higher than those in the other two groups (P<0. 05), while the levels of IGF-1 in two groups were significantly lower than those in the CHC group, and were more lower than the control group (P<0. 05). ⑶Compared the serum ALT, AST and HCV RNA load between CHC with T2DM group and CHC group, there had no significant differ-ence (P>0. 05);however, the proportion of 1b genotype, LSM and APRI score of CHC with T2DM group were significantly higher than those in CHC group(P<0. 05). ⑷ The level of serum IGF-1 was negatively correlated with HOMA-IR, LSM and APRI in CHC with T2DM group (r= -0. 71, -0. 75, -0. 69, P<0. 01). Conclusions The degree of hepatic fibrosis and the damage of IGF-1 synthesis in CHC patients with T2DM were significantly higher than those in non T2DM patients, which might be related to the insulin resistance caused by 1b genotype HCV infection.

Background and objective Radiotherapy is an important treatment for lung cancer. The poor prognosis of lung cancer is largely caused by the high recurrence rate and metastasis of the tumor. Autophagy, which can be induced by radiotherapy, might be associated with DNA repair. The aim of this study is to investigate whether activating autophagy us-ing rapamycin can enhance the radiosensitivity of lung cancer cells and clarify the association of autophagy with DNA repair. Methods The human adenocarcinoma A549 cell line was selected as the experimental subject. The specimens were divided into three groups: control (N), radiation (R), and Rapamycin and radiation (R+ARPA). hTe protein levels of γ-H2AX, Rad51, Ku70/Ku80, p62, and LC3 were determined by Western blot. Autophagosome was observed under a transmission electron microscope, and SF was determined by colony formation assay.Results Compared with group R, the activity of autophagy and the protein expression levels of Rad51 and Ku70/80 were remarkably increased in group R+ARPA.ConclusionhTe radiosensitivity of lung cancer can be promoted by activating autophagy via treatment with Rapamycin, and the process may be associated with DNA repair.
