Objective To investigate the effects of physical and mental rehabilitation exercise on coping style and self-management efficacy of patients with cervical cancer. Methods A total of 60 cervical cancer chemotherapy patients were randomly divided into rehabilitation exercise group and control group, with 30 cases in each group. The patients of control group used conventional methods of nursing care, while patients in rehabilitation training group received the physical and mental rehabilitation exercise positive. The two groups had three months of intervention. Coping style of two groups before and after intervention in cervical cancer patients was contrasted, as well as self-efficacy, complications and nursing satisfaction. Results After the intervention, two groups of patients with cervical cancer, their response were significantly improved, and in the physical and mental rehabilitation exercise group of cervical cancer patients, the coping styles significantly was better than that the control group (P<0.05); after intervention, self-management efficacy of three dimensions and total score in rehabilitation exercise group of cervical cancer patients were significantly improved, and in the physical and mental rehabilitation exercise group of cervical cancer patients, the self-management efficacy of three dimensions and total score were significantly better than those of the control group (P < 0.05); the incidence rate of complications in rehabilitation exercise group after the intervention (6.7%) was significantly lower than it in the control group (33.3%) (P < 0.05); in rehabilitation exercise group, the cervical cancer patients' satisfaction was significantly better than that of the control group (100.0% vs 86.7%)(P < 0.05). Conclusions Nursing care of physical and mental rehabilitation exercise, which is used in cervical cancer patients with radiotherapy and chemotherapy, can significantly improve the coping style and self-efficacy of patients, reduce the incidence of complications, and improve nursing satisfaction.

Objective:To investigate the relationship between cardio-metabolic abnormalities in the first trimester and adverse pregnancy outcomes (APO).Methods:This cohort study recruited singleton pregnancies in the first trimester (6-13 +6 weeks of gestation) from Shenzhen Maternal and Child Health Care Hospital between January 1, 2021, and October 31, 2022. Cardiometabolic markers, including body mass index (BMI), blood pressure, fasting plasma glucose (FPG), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG), were recorded during the first trimester. Incidence of APO, including gestational hypertension, preeclampsia, gestational diabetes mellitus, preterm birth, fetal growth restriction, small for gestational age infant, and placental abruption, was documented. Cardiovascular metabolic abnormalities in the first trimester were defined as meeting one or more of the following criteria: elevated BMI (BMI≥24 kg/m2), elevated TG (TG≥1.7 mmol/L), decreased HDL-C (HDL-C<1.0 mmol/L), elevated blood pressure (systolic pressure≥130 mmHg (1 mmHg=0.133 kPa) and/or diastolic pressure≥85 mmHg), elevated FPG (FPG≥5.6 mmol/L). Enrolled women were categorized into abnormal cardio-metabolic and normal cardio-metabolic groups. Poisson regression was employed to analyze the association between cardio-metabolic abnormalities in the first trimester and APO. Results:The study included 14 197 pregnant women with an age of (32.0±4.1) years. There were 8 139 women in the normal cardio-metabolic group and 6 058 women in the abnormal cardio-metabolic group. Women with cardio-metabolic disorders in the first trimester had a younger gestational age and higher incidence rates of preterm birth, gestational hypertension, preeclampsia, and gestational diabetes mellitus (all P<0.05). In multivariable Poisson regression, elevated BMI ( RR=1.22, 95% CI 1.15-1.29), elevated FPG ( RR=1.59, 95% CI 1.38-1.82), elevated TG ( RR=1.22, 95% CI 1.13-1.31), and elevated blood pressure ( RR=1.50, 95% CI 1.39-1.63) were independent risk factors for APO, while decreased HDL-C ( RR=0.93, 95% CI 0.70-1.23) was not. Elevated blood pressure ( RR=5.57, 95% CI 4.58-6.78), elevated BMI ( RR=1.71, 95% CI 1.40-2.09), and elevated TG ( RR=1.38, 95% CI 1.10-1.74) had the greatest impact on the risk of developing preeclampsia. Elevated FPG ( RR=1.70, 95% CI 1.45-1.99) had the greatest impact on the risk of gestational diabetes. Conclusions:Elevated blood pressure, BMI, TG and FPG in the first trimester are closely related to APO.

OBJECTIVE To observe the changes of static functional connectivity(sFC) and dynamic functional connectivity(dFC) of amygdala subregions in patients with bilateral idiopathic tinnitus and hearing loss(TINHL). METHODS The resting-state functional magnetic resonance imaging(fMRI) data of 30 patients with bilateral tinnitus and hearing loss and 37 normal controls(NCs) were collected to analyze the intensity changes of sFC and dFC in 8 subregions of amygdala and the whole brain in TINHL patients. RESULTS There were no significant differences in age,sex and education between the two groups. Compared with the NCs group,the sFC intensity of the right basolateral subregion and right cerebellar peduncle 1 region,the left basolateral subregion and left orbital medial frontal gyrus and left angular gyrus in TINHL group was significantly decreased. The dFC intensity of left amygdalostriatal subregion and left precuneus in TINHL group was increased,but the dFC intensity was reduced in the left basolateral subregion and right angular gyrus as well as between the right superficial subregion and right medial orbital of superior frontal gyrus. CONCLUSION Among the 8 subregions of amygdala,the bilateral basolateral subregions,the left amygdalostriatal subregion and the right superficial region shown abnormal functional connectivity with other regions of the brain,which are the important parts of emotional abnormalities in TINHL.

Background::Gestational weight gain (GWG) is associated with the risk of gestational diabetes mellitus (GDM). However, the effect of weight gain in different trimesters on the risk of GDM is unclear. This study aimed to evaluate the effect of GWG on GDM during different trimesters.Methods::A birth cohort study was conducted from 2017 to 2020 in Shenzhen, China. In total, 51,205 participants were included comprising two models (early pregnancy model and middle pregnancy model). Gestational weight (kg) was measured at each prenatal clinical visit using a standardized weight scale. Logistic regression analysis was used to assess the risk of GDM. Interaction analysis and mediation effect analysis were performed in the middle pregnancy model.Results::In the early pregnancy model, the risk of GDM was 0.858 times lower (95% confidence interval [CI]: 0.786, 0.937) with insufficient GWG (iGWG) and 1.201 times higher (95% CI: 1.097, 1.316) with excessive GWG after adjustment. In the middle pregnancy model, the risk of GDM associated with iGWG increased 1.595 times (95% CI: 1.418, 1.794) after adjustment; for excessive GWG, no significant difference was found ( P = 0.223). Interaction analysis showed no interaction between GWG in early pregnancy (GWG-E) and GWG in middle pregnancy (GWG-M) ( F = 1.268; P = 0.280). The mediation effect analysis indicated that GWG-M plays a partial mediating role, with an effect proportion of 14.9%. Conclusions::eGWG-E and iGWG-M are associated with an increased risk of GDM. Strict control of weight gain in early pregnancy is needed, and sufficient nutrition should be provided in middle pregnancy.
