Objective:To explore the latent classes of fear of childbirth in late pregnancy women and its relationship with sense of coherence, providing reference for precise support interventions in clinical practice.Methods:From January to September 2023, convenience sampling was used to select 304 pregnant women who underwent antenatal examination at the Obstetrics Clinic of Affiliated Hospital of Hangzhou Normal University as participants. The General Information Questionnaire, Childbirth Attitudes Questionnaire, and the Sense of Coherence Scale-13 (SOC-13) were used for questionnaire survey. Latent profile analysis was used to explore the categories of fear of childbirth in late pregnancy women, and analyzed differences of SOC-13 scores among women with different categories of fear of childbirth.Results:Fear of childbirth in 304 late pregnant women was divided into three latent classes, including low-level fear group of (50.0%, 152/304), moderate-level fear group of (35.2%, 107/304), and high-level fear group of (14.8%, 45/304). ANOVA analysis showed that there were statistically significant differences in total score and dimension scores of SOC-13 among late pregnancy women with three different classes of fear of childbirth ( P<0.05) . Conclusions:There are three latent classes of fear of childbirth in late pregnancy women. The sense of coherence among pregnant women affects their fear of childbirth. Nursing staff should address the heterogeneity of fear of childbirth in late pregnancy women, starting from sense of coherence, and take targeted intervention measures to reduce the fear of childbirth in late pregnancy women.

Objective·To explore the effects of hypertension and dyslipidemia on cognitive function in the elderly.Methods·A dynamic population cohort was established by using prospective cohort study methods.In 2019,a complete cohort was selected from residents aged 65 and above who voluntarily participated in a free physical examination program in a community in Shanghai,serving as the baseline cohort.In 2022,512 community-dwelling elderly aged 67 to 93 were randomly selected from the same community as the follow-up cohort for the study.The collected date included residents' health records,various physical examination measurements,and Mini-mental State Examination(MMSE)scale scores.Results·Of the 512 cases that were followed up,the valid sample size was reduced to 495 after data cleaning.According to the baseline and follow-up cognitive assessments and changes,the cases were categorized into three cognitive groups:the improvement group,the normal group,and the decline group.The prevalence of hypertension in the decline group was 43.14%higher than that in the improvement group and 24.39%higher than that in the normal group(66.67%in the decline group vs 23.53%in the improvement group,P=0.011;66.67%in the decline group vs 42.28%in the normal group,P=0.040).Total cholesterol(TC)in the improvement group was lower than that in the normal group[improvement group(4.38±1.04)mmol/L vs normal group(5.11±1.12)mmol/L,P=0.009].Additionally,TC in the decline group in 2022 was higher than that in 2019[paired difference(0.46±0.87)mmol/L,95%CI 0.08?0.84,P=0.021].LDL-Ch in the improvement group was lower than that in the normal group[improved group(2.51±0.92)mmol/L vs normal group(3.07±1.00)mmol/L,P=0.024],and their HDL-Ch in 2022 was higher than that in 2019[paired difference(0.16±0.20)mmol/L,95%CI 0.06?0.26,P=0.005].The results of multinomial Logistic regression showed:TC in the improved group was lower than that in the normal group[β=4.12,OR=61.64,95%CI 1.52?2494.07,P=0.029]and the decline group[β=5.88,OR=357.35,95%CI 4.54?28149.75,P=0.008];the TAG[β=1.85,OR=6.34,95%CI 1.05?38.43,P=0.045],LDL-Ch[β=5.61,OR=274.06,95%CI 3.65?20567.57,P=0.011],and hypertension[β=1.90,OR=6.69,95%CI 1.53?29.16,P=0.011]in the decline group were higher than those in the improvement group;the age of the decline group was greater than that of the normal group[β=0.08,OR=1.08,95%CI 1.00?1.16,P=0.041],and the education level was lower than that of the normal group[β=1.22,OR=3.39,95%CI 1.28?8.94,P=0.014].Conclusion·Low TC and LDL-Ch and high HDL-Ch are beneficial to cognitive improvement.Conversely,hypertension,high TC,high TAG,high LDL-Ch,low education level,and advanced ages are risk factors for cognitive decline.

Objective:To understand the current status of clinical guidelines and consensus for lung cancer chemotherapy, evaluate and analyze the quality of lung cancer chemotherapy treatment guidelines, and provide references for the revision and improvement of lung cancer chemotherapy clinical decision-making and guidelines.Methods:Search Pubmed, EMbase, Cochrane Library (Cochrane Library), China Knowledge Network, Wanfang Database, China Biomedical Literature Database and other related databases and clinical practice guidelines related to lung cancer chemotherapy, and screen the literatures according to the established inclusion exclusion criteria. Use the appraisal of guidelines for research and evaluation Ⅱ (AGREE Ⅱ) and reporting items for practice guidelines in healthcare (RIGHT) tools to compare and evaluate the quality of the included guides and the level of reporting specifications.Results:A total of 14 guidelines were included. The assessment results of AGREE Ⅱ showed that the average score of scope and purpose was 94 points, the average score of stakeholder involvement was 60 points, the average score of rigour of development was 43 points, the average score of clarity of presentation was 88 points, the average score of applicability was 50 points, the average score of editorial independence was 61 points. Seven guidelines were evaluated as A level, 6 guidelines were evaluated as B level, 1 guideline was evaluated as C level. The assessment results of RIGHT showed that, in addition to the basic information, the included guidelines have many deficiencies in 6 areas including background, evidence, recommendation, review and quality assurance, funding, declaration and management of interests and other information, and the normative gap between domestic and foreign guides was large.Conclusions:The overall quality of clinical guidelines for lung cancer chemotherapy is high, but the standardization needs to be strengthened. There is a big gap between the quality and standardization of domestic and foreign guides. Further developments of high-quality clinical practice guidelines and guidelines consistent with our country′s actual situation are needed.

Objective:To investigate the effect of hemoglobin on Shp2 expression in brain tissues and adherens junction in blood brain barrier in rats after cerebral hemorrhage.Methods:Eighty male SD rats were randomly allocated into sham-operated group and groups of cerebral hemorrhage for 6 h, 24 h, 3 d, and 7 d ( n=16). Rat models in the groups of cerebral hemorrhage were established by intracerebral injection of 20 μL of hemoglobin. Six h, 24 h, 3 d, and 7 d after injection, neurological functions were assessed by Longa scale; brain water content and brain organ coefficient in the harvested cerebral tissues were calculated by wet-dry weighting method; Shp2 mRNA expression was analyzed by real-time fluorescence quantification reverse transcription PCR (qRT-PCR); Shp2 positive neurons was detected by immunohistochemistry; the protein expressions of Shp2, α-catenin, β-catenin and vascular endothelial (VE)-cadherin, and phosphorylated (p-) α-catenin, p-β-catenin and p-VE-cadherin were explored by Western blotting. Results:As compared with those in the sham-operated group, Longa scale scores in groups of intracerebral hemorrhage for 6 h, 24 h, 3 d and 7 d were significantly increased ( P<0.05). As compared with the sham-operated group, groups of intracerebral hemorrhage for 24 h, 3 d and 7 d had significantly increased brain water content and brain organ coefficient, statistically reduced Shp2 mRNA expression, statistically samller amount of Shp2 positive neurons, and statistically reduced Shp2 protein expression, and significantly increased protein expressions of p-α-catenin, p-β-catenin and p-VE-cadherin ( P<0.05). Conclusion:Intracerebral injection of hemoglobin can downregulate Shp2 expression and promote phosphorylation of adherens junction proteins, therefore induce the disruption of adherens junction, which might be a critical mechanism of blood-brain barrier disruption and brain edema.

Objective To explore the association of fibroblast growth factor-23 (FGF23) with abdominal aortic calcification(AAC) and adverse outcomes in maintenance hemodialysis patients.Methods One hundred and fourteen cases of MHD patients were collected prospectively.Serum intact FGF23 was detected by ELISA.Abdomen lateral plain was used as a criteria to determine the abdominal aortic calcification and the abdominal aortic calcification score was counted.Logistic regression analysis was used to determine the risk factors of AAC.Kaplan-Meier analysis was applied to compare the survival rate among different groups and COX regression analysis was used to determine the association of FGF23 and mortality in MHD patients.Results Seventy-six patients present abdominal aortic calcification.The median of AACS was 4.0(0.0,11.0).The median level of FGF23 was 7277.4(2535.0,9990.8) pg/ml.The median follow-up duration was 72.0(67.8,72.8) months.During the follow-up,22 patients (19.3％) died of all-cause death and 17 cases (14.9％) died of cardiovascular diseases.Serum FGF23 level was positively correlated with AAC (r=0.285,P=0.002).Logistic regression analysis showed that longer age (OR=1.059,95％CI:1.020-1.100,P=0.003) and dialysis vintage (OR=I.009,95％CI 1.000-1.017,P=0.039),smoking history (OR=3.010,95％CI 1.177-7.696,P=0.021) and higher FGF23 level(OR=2.831,95％CI 1.010-7.937,P=0.048) were independent risk factors of moderate to severe AAC in MHD patients.Kaplan-Meier survival curves showed that the patients with AACS≥ 5 had significantly higher all-cause mortality(P=0.028) and CVD mortality (P=0.035) than those with AACS ＜ 5.However,the Kaplan-Meier analysis showed no significant difference regarding the level of serum FGF23 with the all-cause and CVD mortality.Cox regression demonstrated that FGF23 was not associated with increased mortality risk,neither in crude nor in multivariate adjusted models.Conclusions Abdominal aortic calcification had a high prevalence in MHD patients.The all-cause and CVD mortality was higher in patients with moderate to severe AAC.FGF23 was an independent risk factor of moderate to severe AAC,but it can't yet be a predictor for the allcause and CVD mortality of MHD patients.

Objective To research the effect of letrozole combined with clomiphene on women with polycystic ovary induced infertility and the effect on matrix metalloproteinases-9(MMP-9),vascular endothelial growth factor(VEGF)and hepatocyte growth factor(HGF)levels.Methods 108 patients with polycystic ovary syndrome combined with infertility from February 2013 to August 2015 in our hospitolwere divided into control group and experimental group by lottery,54 cases in each groups,control group treated with clomiphene,the experimental group based on control group treatment with letrozole,the linical curative effect,MMP-9,VEGF and HGF level,sex hormones,insulin resistance index,adverse drug reactions of two groups were compared.Results The number of ovulation,advantage of ovulation number,normal rate of menstruation,ovulation rate and pregnancy ratesofin experimental group was higherthan the control group,the difference was statistically significant(P<0.05).The MMP-9,VEGF and HGF levels of experimental group was lower than the control group,the difference was statistically significant(P<0.05).The sex hormone level of experimental group was better than that of control group(P<0.05).The adverse reactions was no differences between the two groups.Conclusion The efficacy of letrozole combined with clomiphene in treatment of polycystic induced infertility,can inhibits MMP-9,VEGF and HGF expression,and with high safety.

Objective To determine the relationship between serum soluble Klotho (sKL) level and adverse outcome in maintenance hemodialysis (MHD) patients.Methods One hundred and twenty nine cases of MHD patients were collected prospectively.Serum sKL was detected by ELISA.Abdomen lateral plain was used as a criterion to determine the abdominal aortic calcification.The abdominal aortic calcification score (AAC) was calculated.Cox regression analysis was used to determine the risk factor of cardiovascular death (CVD) in MHD patients.Kaplan-Meier showed the relationship between sKL and CVD in MHD patients.Results There were 27 cases (20.9％) of allcause death and 19 cases (14.7％) of cardiovascular death.The median sKL was 612.6(379.2-816.6) nig/L,and log[iPTH] was an independent factor of sKL concentration.Low sKL had high AAC and CVD death rate.Kaplan-Meier method showed that the all-cause death rate was similar between two groups,and CVD death rate increased significantly in low sKL patients (P=0.036).Cox regression indicated that lower sKL level was associated with high CVD death rate [OR=0.352,95％CI(0.127-0.977),P=0.045].After adjustment for the general condition,biochemical indicators,the relationship still existed [OR=0.331,95％ CI (0.117-0.933),P=0.037].In no or mild vascular calcification patients (AAC ≤4),compared with high sKL patients,low sKL patients had no significant difference rate in all-cause mortality.The CVD mortality was significantly higher in high sKL (P=0.035) compared with low sKL.In severe calcification group (AAC ＞ 4),all-cause death and CVD death rates were similar between different sKL groups (P=0.991 and 0.522,respectively).Conclusions Lower sKL has the high CVD death rate and sKL level decreasing is an independent risk factor for CVD death in MHD patients.The lower sKL concentration in MHD patients with no or mild calcification may predict CVD mortality.This study suggests that sKL levels may be helpful in predicting the outcome of patients with MHD.

Objective To investigate the relationship between the variation of endothelial progenitor cells (EPC) number and cardiovascular diseases (CVD) in maintenance hemodialysis (MHD) patients ,and discuss the function of EPC in the progression of CVD in MHD. Methods One hundred and fifteen MHD patients over 18 years whose dialysis vintage was over six months from Department of Nephrology, Renji Hospital, Shanghai Jiao Tong University School of Medicine were enrolled. They were divided into CVD group and non ? CVD group by medical history, electrokardiographie (EKG), cardiac ultrasound, peripheral vascular imaging and cardiovascular imaging. Peripheral blood (5 ml) was collected for detecting EPC number by flow cytometry as CD34/CD133/vascular endothelial growth factor receptor 2 (VEGFR2) cells. The EPC number between CVD group and non?CVD group was compared. The relationship between the decrease of EPC number and CVD risks in MHD patients was analyzed by logistic regression analysis. In a three?year follow?up, the death and new CVD events of the two groups were compared in order to discuss the relationship between EPC number and adverse events. Results Among 115 MHD patients, the average age was 61.57 ± 12.76, male/female was 71/44, the average dialysis vintage was (86.24 ± 56.31) months, the average Kt/V was 1.69 ± 0.29 and average ultrafiltration volume was (2.48 ± 0.90) L. Forty?four patients in 115 (38.3%) were with concurrent CVD. The EPC number in CVD group was significantly lower than that in non CVD group (P=0.015). The CVD group had higher serum phosphate (P=0.013), higher glycosylated hemoglobin (P<0.001), but serum calcium, intact parathyroid hormone (iPTH) and other indicators had no significant difference between two groups. Multiple Logistic regression analysis showed that older age (OR=1.061), history of diabetes (OR=9.796), dialysis vintage (OR=1.015), serum phosphate (OR=3.766), decrease of EPC number (OR=0.909) were the independent impact factors of CVD events in MHD patients. There were 22 patients of the 115 MHD patients had encountered a new CVD event in a three?year follow?up between December 2012 and December 2015, 9 patients from the CVD group and 13 patients from the Non?CVD group, and there was no significant difference between two groups (P=0.776). Nine patients from the CVD group and 7 patients from the Non?CVD group died in the follow?up, and there was no significant difference (P=0.111). Seventy?one MHD patients from the non?CVD group were divided into two groups by the median of EPC number. There were 3 patients in the higher EPC number group encountered CVD events and 10 patients in the lower EPC number group encountered CVD events, which had significant difference (P=0.024). Conclusion The decrease of circulating EPC number may be related with CVD events in MHD patients. Even adjusted by age, sex, diabetes, dialysis vintage and serum phosphate, decreased EPC number is still the independent risk factor of CVD events in MHD patients. The decrease of EPC number in MHD patients may be used to predict the occurrence of cardiovascular events.
