Research has shown that intrapersonal, interpersonal, and stress factors are associated with development in marital satisfaction. However, the unique contributions of early predictors and changes in these factors to the development of marital satisfaction have been overlooked. Based on data from 268 Chinese newlywed couples (M[subscript age] = 29.59, SD = 3.25 for husbands; M[subscript age] = 28.08, SD = 2.51 for wives), the current study used latent growth curve model to examine (a) the development of marital satisfaction and the unique contributions of the intrapersonal, interpersonal, and stress predictors to the developmental trajectories (i.e., the initial level and change) of marital satisfaction; (b) whether the intrapersonal, interpersonal, and stress predictors develop over time; and (c) how trajectories of these predictor domains are associated with changes in marital satisfaction. The results indicated that interpersonal variables, rather than intrapersonal or stress predictors at baseline, were associated with both the initial levels of and changes in marital satisfaction; in contrast, only the changes in the stress levels were found to be related to changes in marital satisfaction. The theoretical implications and future directions for this research are discussed.

This study investigates how the residential locations of extended family members influence residential (im)mobility behaviour in the urbanizing and industrializing context of China. It engages with how residential mobility as family adaptive strategies are structured by traditional family beliefs, welfare systems and structural modernization processes. For younger adults who have parents but no adult children, when they co-reside with their parents, they are more likely to move rather than staying put. But they usually move short distances within the county rather than outside the county. This mainly implies a process of moving out of the intergenerational households and establishing their independent households. The presence of their parents at the county scale also deters them from moving outside the county. These young adults seem to be bounded within the county by family ties. Besides, when they have siblings within the county, they are more likely to move outside the county than within the county; siblings near their parents may allow other siblings to move away for job and education opportunities, indicating a responsibility-sharing theory. For older adults who have young adult children but no living parents, they are more likely to move outside the county when their nearest adult child(ren) is outside the county, a strong implication of moving towards their adult children. For those who have both living parents and adult children, they are more likely to stay put or to move locally within the county, rather than moving out the county, when their parents are at the county scale.

Unprecedented urbanisation in China has profoundly reshaped the country's social-spatial structure. Owing to economic suburbanisation and urban redevelopment processes, migrants coming from rural areas are increasingly concentrated in suburbs rather than city centres. Against this backdrop, this paper focuses on residential segregation between migrants and locals, and on geographical (re)structuring between the city centre and suburb. Theil's H Index is used to disaggregate the migrant segregation of each municipality into a within-suburb, a within-centre and a between-centre-suburb component. We use Census data for 258 municipalities in 2000 and 2010; we find that migrant segregation increased in this period. We ascribe this to the increasing segregation of migrants in suburban areas, which offsets the increasingly balanced distribution of migrants between the city centre and suburb. Segregation in city centres also increased slightly in this period. Unexpectedly, less economically developed municipalities, defined by their per capita GDP, tend to be more segregated than their more developed counterparts. Less developed municipalities also have a higher level of suburban employment and housing opportunities in the whole municipality, but feature more segregated suburban spaces and a polarised distribution of migrants between the centre and suburb.

To examine how and when stress affect individual (i.e., psychological health) and relationship well-being (i.e., marital satisfaction) during the COVID-19 pandemic, the present study used latent profile analysis to identify the typologies of communication and investigated whether the typologies would moderate the associations between stress and individual and relationship well-being in a sample of adults living in China (N = 3,354). Results revealed that (a) stress was negatively associated with psychological health and marital satisfaction during the COVID-19 pandemic and that its effect on psychological health was greater than that on marital satisfaction and (b) four profiles were identified: low communication (10%), moderate communication (43%), positive communication (43%), and contradictory communication (5%). Further, the typologies moderated the effects of stress on psychological health and marital satisfaction, but the patterns of moderation differed in psychological health and marital satisfaction.

Background: The efficacy and safety of high‐dose amoxicillin (AMX) and proton pump inhibitors (PPI) dual therapy raises much more attention in recent years. Comparative studies among the dual therapies are required to explore more suitable regimens. This study compared the efficacy, adverse events, and patient compliance of three different high‐dose dual regimens in treatment‐naive patients of Helicobacter pylori (H. pylori) infection. Materials and Methods: The study was a prospective, multicenter, open‐label, randomized controlled trial, including H. pylori‐infected treatment‐naive patients at 12 tertiary hospitals in China. The eligible subjects received high‐dose AMX and esomeprazole (ESO) dual therapy of different regimens. They were randomly assigned to group A (ESO 20 mg plus AMX 750 mg, Qid for 14 days), group B (ESO 40 mg Bid plus AMX 1 g Tid for 14 days), or group C (ESO 20 mg plus AMX 1 g, Tid for 14 days). The eradication rates, adverse events, and patient compliance of the three groups were compared. Results: Between April 2021 and January 2022, a total of 1080 subjects were screened and 945 were randomized. The eradication rates in groups A, B, and C were 88.6% (95% CI 84.5%–91.9%), 84.4% (95% CI 80.0%–88.3%), and 86.7% (95% CI 82.4%–90.2%; p =.315), respectively, based on intention‐to‐treat analysis; 90.3% (95% CI 86.4%–93.3%), 85.5% (95% CI 81.1%–89.2%), and 87.8% (95% CI 83.6%–91.2%; p =.197), respectively, according to modified intention‐to‐treat analysis; and 90.4% (95% CI 86.5%–93.5%), 85.8% (95% CI 81.4%–89.5%), and 88.3% (95% CI 84.1%–91.7%; p =.202) in per‐protocol analysis. History of antibiotics use in 2 years reduced eradication effect in group B (ESO 40 mg Bid, AMX 1 g Tid). The modified intention‐to‐treat eradication rates were 81.4% vs 90.0% among those with or without a history of antibiotics use in group B (p =.031). The adverse event rates were 13.7%, 12.7%, and 12.1% in groups A, B, and C, respectively (p =.834). Patient compliance of the three groups was similar. Conclusions: Two optimized AMX and PPI dual regimens (ESO 40 mg Bid or 20 mg Tid plus AMX 1 g Tid for 14 days) had similar efficacy, safety and compliance as compared with classical dual regimen (ESO 20 mg plus AMX 750 mg Qid for 14 days) in H. pylori‐infected treatment‐naive patients.

We examined hypothalamic–pituitary–adrenal stress reactivity as an indicator of differential susceptibility in moderating the links between family socioeconomic status (SES) and executive function (EF) in three-year-old urban Chinese children. The participants included 77 children (36 girls) and their families. Family income, parents' education, and level of occupation were reported by the mothers and aggregated into a composite index of family SES. We assessed the children's biological reactivity by salivary cortisol responses to a mild stressor, which we calculated by the area under the curve with respect to increase. We measured EF skills with a series of laboratory tasks. The results revealed significant interactive effects of SES and cortisol reactivity on children's cognitive inhibitory control. More specifically, SES was significantly related to cognitive inhibitory control for children with higher cortisol reactivity. Conversely, for children with lower cortisol reactivity, there were no significant correlations between SES and cognitive inhibitory control. Region of significance analyses indicated a moderating effect supporting the "bright side" of differential susceptibility, meaning that high cortisol reactive children were more likely to benefit from high levels of SES. The results also manifested a direct association between SES and children's working memory, and this association was not dependent on the features of cortisol reactivity. SES did not relate to hot EF. The results highlight the SES disparity in different EF elements and may help in the development of targeted interventions. Highlights: Effects of family socioeconomic status (SES) and its interplay with cortisol reactivity on children's executive function (EF) were tested in Chinese children. Cortisol reactivity moderated the association between family SES and children's cognitive inhibitory control. SES was significantly related to cognitive inhibitory control for children with higher but not lower cortisol reactivity. Further analyses indicated a moderating effect, supporting the "bright side" of the differential susceptibility model. The association between SES and children's working memory did not vary with the features of cortisol reactivity. [ABSTRACT FROM AUTHOR]

Objective: To assess the accuracy of injury-related hospitalization diagnoses by physicians in China.Methods: 62,269 hospitalizations between 2014 and 2016 at a large hospital in Changsha, China were assessed. We considered three types of diagnostic errors: under-reporting, lack of cause specificity, and misclassification across injury causes. Diagnosis and coding of diseases were ascertained by professional coders based on the tenth International Classification of Disease (ICD-10). Chi square tests examined the proportion difference across subgroups of patient demographics, injury intent, and injury cause.Results: The 62,269 records included 1011 injury-induced hospitalizations, but physicians' diagnoses only reported 405 (40%) of the 1011 hospitalizations as injury-related. The proportions of under-reporting, lack of cause specificity, and misclassification errors, respectively, were 50.5%, 7.9% and 1.5%. The proportion of diagnostic errors was relatively similar across patient sex, intent of injury, and cause of injury subgroups, but varied substantially across patient age groups.Conclusion: Physicians' diagnoses frequently omitted injury-induced hospitalizations. Such errors will impact injury research and policy-making when they are undetected and uncorrected. [ABSTRACT FROM AUTHOR]

Background. Since December 2019, novel coronavirus- (SARS-CoV-2) infected pneumonia (COVID-19) has rapidly spread throughout China. This study is aimed at describing the characteristics of COVID-19 patients in Wuhan. Methods. 199 COVID-19 patients were admitted to Wuhan Red Cross Hospital in China from January 24th to March 15th. The cases were divided into diabetic and nondiabetic groups according to the history of taking antidiabetic drugs or by plasma fasting blood glucose level at admission, and the difference between groups were compared. Results. Among 199 COVID-19 patients, 76 were diabetic and 123 were nondiabetic. Compared with nondiabetics, patients with diabetes had an older age, high levels of fasting plasma glucose (FPG), D-dimer, white blood cell, blood urea nitrogen (BUN) and total bilirubin (TBIL), lower levels of lymphocyte, albumin and oxygen saturation (SaO2), and higher mortality (P < 0.05). The two groups showed no difference in clinical symptoms. Diabetes, higher level of D-dimer at admission, and lymphocyte count less than 0.6 × 10 9 /L at admission were associated with increasing odds of death. Antidiabetic drugs were associated with decreasing odds of death. Treatment with low molecular weight heparin was not related to odds of death. Conclusion. The mortality rate of COVID-19 patients with diabetes was significantly higher than those without diabetes. Diabetes, higher level of D-dimer, and lymphocyte count less than 0.6 × 10 9 /L at admission were the risk factors associated with in-hospital death. [ABSTRACT FROM AUTHOR]

Background: Postpartum depression causes harm to both mothers and infants. The purpose of this study was to find out several potential risk factors, and to identify the intrinsic interrelationships between factors and postpartum depression by constructing a path model. The results of this study may help to control the increasing incidence of maternal postpartum depression.Methods: The study was based on a sample of mothers from a cross-sectional study which was set up at 4 weeks after a mother had childbirth and was conducted in three streets at Kaifu District of Changsha in Hunan province from January to December 2015. Questionnaires were distributed to subjects who responded to questions concerning factors related to pregnancy, delivery and infants within 4 weeks after childbirth. The Edinburgh Postnatal Depression Scale (EPDS) was used to measure postpartum depression. Chi-square test was used to detect significant differences between non-postpartum depression group and postpartum depression group. A path model was constructed to explore the interrelationships between variables, and to verify the relationships between variables and postpartum depression.Results: The proportion of maternal postpartum depression was 6.7%. Univariate analysis showed that there were significant differences between non-postpartum depression group and postpartum depression group (all P-values <0.05) on the part of maternal age, parity, frequent exposure to mobile phone during pregnancy, gestational hypertensive disorders, fetus number, premature delivery, birth weight, initiation of breastfeeding, mode of feeding, infant illness within 4 weeks after delivery and infant weight at 4 weeks. Path analysis results showed that the final model could be fitted well with sample data (P = 0.687, CMIN/DF = 0.824, NFI = 0.992, RFI = 0.982, IFI = 1.002, TLI =1.004, CFI = 1.000 and RMSEA < 0.001). Frequent exposure to mobile phone during pregnancy, maternal age and gestational hypertensive disorders had both direct and indirect effects on postpartum depression. Mode of feeding and infant weight at 4 weeks, which was the most total effect on postpartum depression, had only a direct impact on postpartum depression. Fetus number, premature delivery, initiation of breastfeeding and birth weight had only an indirect influence on postpartum depression.Conclusion: The findings of this study suggest that constructing a path analysis model could identify potential factors and explore the potential interrelations between factors and postpartum depression. It is an effective way to prevent maternal postpartum depression by taking appropriate intervention measures and carrying out health education for pregnant women. [ABSTRACT FROM AUTHOR]

Root-lesion nematodes ( Pratylenchus spp.), the most common parasitic nematodes of plant roots, cause root lesions on many taxa of host plants in temperate regions around the world. In this study to isolate and identify plant parasitic nematodes in maize in Shandong Province, China, four fields with yellowish, stunted plants with symptoms like nutrient deficiencies were sampled in the suburb of Taian city, China. The entire root system was collected, and any nematodes were extracted from maize roots. Nematodes in 10 isolations were identified as Pratylenchus neglectus or P. scribneri based on morphological characteristics and molecular analyses. This is the first report of P. neglectus infecting maize in China. [ABSTRACT FROM AUTHOR]

Evolution of flavonols from the onset of ripening to commercial harvest was compared in seven grape cultivars ( Vitis vinifera L.) in Qilian region of Gansu Province in northwest China for two consecutive years. The cultivars were three white-skinned (Chardonnay, Semillon, Italian Riesling), one pink-skinned (Gewurztraminer) and three red-skinned (Cabernet Sauvignon, Cabernet Gernischt and Merlot). Isorhamnetin-3- O-glucoside was found in the pink 'Gewurztraminer' grape and the three red cultivars, but not in the whites, while myricetin derivatives were found to be specific to the red grapes. Our results indicate that the flavonol synthesis in Gewurztraminer should be similar to that in white cultivars that do not have a flavonoid 3′,5′-hydroxylase-mediated branch pathway. In comparison with the white and pink grapes, the type and level of quercetin and kaempferol derivatives detected in red grapes were relatively variable, which may be attributable to the presence of an additional myricetin branch in flavonol biosynthesis pathway of red grape cultivars, consequently expanding the range of metabolite variation. We also consider that rain during the sampling period may be a major factor causing these changes in the flavonol profile found between the two vintages. [ABSTRACT FROM AUTHOR]

Objective: To assess the health-related quality of life (QOL) of doctors and nurses using the recent free-access data. Methods: The health-related QOL data of doctors and nurses came from a sub-survey of the Fourth National Health Services Survey (NHSS) of China in 2008, which used the European Quality of Life-5 Dimensions 3 level version (EQ-5D-3L) to measure the QOL. We used logistic regression to compare the percentage of respondents reporting any problems for each dimension of the EQ-5D-3L descriptive system between inhabitants aged 15-64 years and doctors and nurses. Results: Fewer doctors and nurses reported problems in mobility (1.9%) than inhabitants aged 15-64 years (2.9%) (odds ratio = 0.65). No difference was detected in self-care problem. Compared with inhabitants aged 15-64 years, a relatively large proportion of doctors and nurses reported problems in usual activities (3.4% vs. 2.7%; odds ratio = 1.27), pain/discomfort (18.1% vs. 6.7%; odds ratio = 3.08), and anxiety/depression (24.6% vs. 5.1%; odds ratio = 6.07). The EQ-VAS score mean of doctors and nurses approached that of inhabitants aged 15-64 years (82 vs. 79). Conclusion: Compared with inhabitants aged 15-64 years, doctors and nurses have relatively poor health in usual activities, self-reporting pain/discomfort, and anxiety/depression.
