Objective:To investigate the self-care contribution and binary coping level of spouse caregivers for middle-aged and young stroke patients and explore the relationship between the two, in order to improve the quality of self-care contribution of spouse caregivers to middle-aged and young stroke patients.Methods:A cross-sectional survey was conducted among 200 middle-aged and young stroke patients ′ spouse caregivers in the People ′s Hospital of Xinjiang Uygur Autonomous Region from January to June 2023 by the general data questionnaire, the Caregiver Contribution to Self-care of Stroke Patient Scale, the Dyadic Coping Inventory. The correlation between self-care contributions and binary coping strategies of spousal caregivers was analyzed, and the factors that affect their self-care contributions were screened. Results:Finally, 192 middle-aged and young stroke patients ′ spouse caregivers were included, including 70 males and 122 females, aged 18-59 years old. The total score of self-care contribution of spousal caregivers of middle-aged and young stroke patients was (75.43 ± 6.80) points, and the total score of binary coping was (117.12 ± 9.59) points, both of which were positively correlated ( r=0.691, P<0.05). Hierarchical regression analysis showed that after controlling for the influence of general data, binary coping could explain 28.4% variation in the self-care contribution of spouse caregivers of middle-aged and young stroke patients ( P<0.05). Conclusions:The duality coping level positively predicts the quality of spouse caregivers ′ self-care contribution to middle-aged and young stroke patients. Medical staff should assess the dual coping level of middle-aged and young stroke patients and their spouses, and carry out targeted dual intervention measures to improve the quality of caregivers' contribution to stroke patients ′ self-care.

Healthcare professionals should be aware that genital mycoplasma infections are common in clinical practice, which are mainly caused by Mycoplasma hominis (Mh), Ureaplasma urealyticum (UU) and Mycoplasma genitalium (Mg). Mh and UU can colonize the urogenital tract of healthy individuals and are associated with bacterial vaginosis, urethritis, pelvic inflammatory disease, infertility and preterm birth; while Mg may cause urethritis, cervicitis, endometritis and pelvic inflammatory disease, bringing more threat to reproductive health in women. Mh and UU can be detected by culture on special media, while isolating Mg and subtyping UU require molecular biological techniques. Currently, there are no unified guidelines for the screening and treatment of genital mycoplasmas infections worldwide. The article reviews the progress of screening, diagnosis and treatment strategies for mycoplasma infections in female genital tract, aiming to provide a reference for clinical management of this conditon.

Objective:To explore the changes in early postpartum pelvic floor muscle strength following the implementation of the new labor process.Methods:This retrospective cohort study selected 1 834 primiparous women with singleton, full-term pregnancies who delivered at Peking University First Hospital from February 2011 to March 2016 and had a pelvic floor re-examination 6-8 weeks postpartum. Out of these, 738 cases who followed the old labor process before 2014 were categorized as the old process group, and 1 096 cases who followed the new labor process after 2014 were categorized as the new process group. Basic data, childbirth information, and postpartum pelvic floor muscle strength of the two groups were compared. Data were statistically analyzed using t-test, Chi-square test, Mann-Whitney U test, Wilcoxon rank-sum test, and ordered multicategory logistic regression to assess the impact of the new and old labor process and other factors on pelvic floor muscle strength. Results:The total duration of labor, as well as the duration of the first, second, and third stages of labor, were longer in the new process group than in the old process group [549.0 min (360.0-768.0 min) vs. 482.5 min (328.0-635.0 min), 465.0 min (297.5-672.5 min) vs. 420.0 min (285.0-555.0 min), 42.0 min (24.0-74.0 min) vs. 27.0 min (18.0-45.0 min), with Z-value of－5.72,－3.95, and－9.28, all P<0.05). The rates of vaginal delivery and labor analgesia were higher in the new process group [72.1% (790/1 096) vs. 67.2% (496/738), χ2=7.41; 67.4% (739/1 096) vs. 53.4% (394/738), χ2=36.82; both P<0.05]. There were no statistically significant differences in the comparison of Class Ⅰ and Class Ⅱ muscle strength grades between the two groups (all P>0.05). Conclusion:There was no significant decline in early postpartum pelvic floor muscle strength following the implementation of the new labor process standards.

Objective To investigate the clinical characteristics and immunotherapy effect of myelin oligodendrocyte glycoprotein antibody(MOG-Ab)-associated disorders(MOGAD)onset with spinal cord injury.Methods Clinical data of 2 children with MOGAD onset with spinal cord injury were retrospectively analyzed.Results The first symptoms of 2 children were both lower limbs fatigue.After testing the full-length MOG-Ab in both serum and CSF and MRI scanning,they were diagnosed as MOGAD onset with spinal cord injury.The clinical symptoms were relieved after hormone impact treatment,and the range of abnormal signals were reduced by reexamination.After discharge,the patient was followed up for more than 5 months,and the clinical symptoms were cured without recurrence.Conclusions MOGAD onset with spinal cord injury is a rare disease type.Its early clinical manifestations may be neck,back and waist discomfort,gradually aggravated limb weakness,urination and defecation dysfunction.Imaging examination shows abnormal signals of multi-segmental spinal cord,and MOG-Ab could be detected in CSF and peripheral blood.Early identification and diagnosis and timely application of hormone impact treatment can help to quickly relieve clinical symptoms and improve prognosis.

BACKGROUND: Previous studies have shown that lymph node metastasis only occurs in some mixed ground-glass nodules (mGGNs) which the pathological results were invasive adenocarcinoma (IAC). However, the presence of lymph node metastasis leads to the upgrading of tumor-node-metastasis (TNM) stage and worse prognosis of the patients, so it is important to perform the necessary evaluation before surgery to guide the operation method of lymph node. The aim of this study was to find suitable clinical and radiological indicators to distinguish whether mGGNs with pathology as IAC is accompanied by lymph node metastasis, and to construct a prediction model for lymph node metastasis. METHODS: From January 2014 to October 2019, the patients with resected IAC appearing as mGGNs in computed tomography (CT) scan were reviewed. All the lesions were divided into two groups (with lymph node metastasis or not) according to their lymph node status. Lasso regression model analysis by applying R software was used to evaluate the relationship between clinical and radiological parameters and lymph node metastasis of mGGNs. RESULTS: A total of 883 mGGNs patients were enroled in this study, among which, 12 (1.36%) showed lymph node metastasis. Lasso regression model analysis of clinical imaging information in mGGNs with lymph node metastasis showed that previous history of malignancy, mean density, mean density of solid components, burr sign and percentage of solid components were informative. Prediction model for lymph node metastasis in mGGNs was developed based on the results of Lasso regression model with area under curve=0.899. CONCLUSIONS Clinical information combined with CT imaging information can predict lymph node metastasis in mGGNs.

Objective: To analyze the current nutritional composition of commonly consumed prepackaged foods among children in Chengdu and to provide a scientific basis for health education among children and adolescents. Methods: Based on the 3 day and 24 hour dietary data of children aged 6-12 in Chengdu of the Southwest China Childhood Nutrition and Growth Cohort from 2021 to 2022, the nutritional information of prepackaged foods was collected by combining offline and online methods. All foods were classified step by step, and the nutrient content of each 100 g or 100 mL food was counted and graded. Results: A total of 1 902 children s prepackaged foods in 23 sub categories of 10 major categories were investigated. Nuts and seeds, snack foods, instant foods and other dairy products had higher total energy(2 476, 2 027, 1 728, 1 816 kJ/100 g), with the nutrient reference value percentage(NRV%) exceeding 20%. Fish, poultry, meat, eggs and their products had the highest protein content(22.8 g/ 100 g ) with an NRV% of 38%, nuts and seeds had the highest fat content(47.5 g/100 g) with an NRV% of 79%, confectionery and jelly had the highest carbohydrate content(82.1 g/100 g) with an NRV% of 27%, and seasoning flour products had the highest sodium content with an NRV% up to 118%. Seasoning flour products and instant foods were mostly high sodium, high fat and high carbohydrate food. Baked and puffed foods were almost high fat and high carbohydrate. Fish, poultry, meat, eggs, beans and their products were rich in protein but mostly high in sodium. Beverages and cold drinks were low in other nutrients except carbohydrate. Conclusion The nutrient content of various prepackaged foods commonly consumed by children in Chengdu are quite different. Most of the foods consumed by children are high sodium, high fat and/or high carbohydrate. Nutrition education should be strengthened to help children choose healthy foods.

Target identification of bioactive compounds is important for understanding their mechanisms of action and provides critical insights into their therapeutic utility. While it remains a challenge, unbiased chemoproteomics strategy using clickable photoaffinity probes is a useful and validated approach for target identification. One major limitation of this approach is the efficient synthesis of appropriately substituted clickable photoaffinity probes. Herein, we describe an efficient and consistent method to prepare such probes. We further employed this method to prepare a highly stereo-congested probe based on naturally occurring triterpenoid betulinic acid. With this photoaffinity probe, we identified tropomyosin as a novel target for betulinic acid that can account for the unique biological phenotype on cellular cytoskeleton induced by betulinic acid.

Objective:To analyze the incidence and risk factors of postoperative new-onset atrial fibrillation(POAF) after lobectomy.Methods:A monocentric ambispective cohort study was conducted. The retrospective cohort included 1 902 patients who underwent lobectomy in our hospital between January 2017 and December 2019. The prospective cohort included 692 patients who underwent lobectomy in our hospital between August 2020 and July 2021. A total of 2 594 patients were enrolled in this study. The median age of enrolled patients was 61 years(interquartile range, 54-67 years), and the cohort consisted of 1 384(51.97%) females and 1 246(48.03%) males. Baseline and perioperative clinical data of enrolled patients were collected. Univariate and multivariate logistic regression analyses were performed to identify the risk factors related to POAF. Results:There was no patient died in hospital after surgery. A total of 111 cases of POAF were followed up during the postoperative hospital period, and the incidence of POAF was 4.28%. Multivariate regression analysis found that the elderly patients(aged 60 and above)( OR=1.58, 95% CI: 1.01-2.47, P=0.044), history of percutaneous coronary intervention( OR=2.50, 95% CI: 1.04-6.03, P=0.041), history of arrhythmia excluding atrial fibrillation/flutter( OR=3.96, 95% CI: 1.95-8.00, P<0.001), left upper lobectomy( OR=1.73, 95% CI: 1.11-2.68, P=0.015), low preoperative albumin level( OR=1.07, 95% CI: 1.00-1.14, P=0.048) and large cell neuroendocrine carcinoma( OR=4.70, 95% CI: 1.38-15.98, P=0.013) were independent risk factors for POAF after lobectomy. Conclusion:The incidence of POAF after lobectomy is 4.28% in this study. Elderly patients(aged 60 and above), history of percutaneous coronary intervention, history of arrhythmia excluding atrial fibrillation/flutter, left upper lobectomy, low preoperative albumin level, and large cell neuroendocrine carcinoma are the independent risk factors related to POAF after lobectomy.

Objective:To explore the underlying genetic causes of neonatal encephalopathy complicated with perinatal asphyxia.Methods:From the neonates recruited to the Neonatal Genome Project of Children′s Hospital of Fudan University between January 2016 and January 2019, 113 neonates with neonatal encephalopathy and acute peripartum or intrapartum event or Apgar score ≤7 were enrolled in this study. The clinical data, laboratory results, the findings of electroencephalograph and magnetic resonance imaging or head ultrasound, and the genetic information were retrospectively analyzed.Results:Of the 133 neonates with neonatal encephalopathy and acute peripartum or intrapartum event or Apgar score ≤7 scores, 77 (57.9%) were males, 56 (42.1%) were female, 56 (42.1%) were delivered via cesarean section, and 77(57.9%) were born by vaginal delivery. Among these cases, 68 (51.1%) were diagnosed of hypoxic ischemic encephalopathy, 25 (18.8%) had intracranial hemorrhage, 20 (15%) were related to genetic diseases, and 5 (3.8%) had sepsis without central nervous infection. A total of 20 cases with positive results by next-generation sequencing test were identified, including 19 cases with pathogenic variations and 1 case with variation of uncertain significance. These 20 cases included 4 cases with congenital myopathy (2 cases of MTM1 gene pathogenic variants, 1 case of ACTA1 and 1 case of RYR1 gene pathogenic variants), 4 cases with genetic syndrome (2 cases of CHD7 gene pathogenic variants, 1 case of PTN11 gene pathogenic variant, and 1 case of NSDHL gene pathogenic variant), 3 cases with metabolic disorders (1 case of OTC gene pathogenic variant, 1 case of MTHFR gene pathogenic variant, and 1 case of ALDH7A1 gene pathogenic variant), 2 cases with epileptic encephalopathy (1 case of KCNT1 and 1 case of PACS2 gene pathogenic variants), 1 case with congenital central hypoventilation syndrome (PHOX2B gene pathogenic variant) and 6 cases with copy-number pathogenic variations. Among these 20 cases, 8(40.0%) neonates were presented with persistent hypotonia, 7(35.0%) neonates with seizures, and 5(25.0%) neonates with congenital malformation. Genetic counseling and further follow-up were performed or suggested for these 20 cases; 4 neonates were deceased, 10 neonates underwent palliative care, and 6 neonates were improved after supportive care and their further follow-up plan were performed in clinics.Conclusions:Genetic diseases are not rare in neonates with neonatal encephalopathy complicated with perinatal hypoxia event. The common causes in these neonates include congenital myopathy, metabolic disorders, genetic syndrome, and epilepsy encephalopathy.
