Objective: To explore the association between maternal lipid levels during pregnancy and the risk of overweight and obesity in offspring at 3 years of age, providing scientific evidences for the prevention and control of childhood obesity. Methods: A total of 2 432 mother-child pairs with maternal lipid tests during pregnancy and offspring s physical growth data at 3 years of age were included from the Borin in Guangzhou Cohort Study up to September 2021. Lipid indicators, including high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol(LDL-C), triglycerides (TG), and total cholesterol (TC), were measured at 13-19 +6 weeks (mid pregnancy) and 32-39 +6 weeks (late pregnancy). Children s body mass index (BMI) Z score were calculated according to the World Health Organization s growth standards for children under 5 years old. The lipid Z score were divided into four quartiles: Q 1, Q 2, Q 3 and Q 4. Linear regression was used to analyze the relationship between maternal lipid levels during pregnancy and offspring’s BMI Z score at 3 years of age. Poisson regression with a robust error variance was employed to evaluate the association between maternal lipid levels during pregnancy and the at risk of overweight and obesity in offspring at 3 years of age, after adjusting for maternal age at conception, education level, parity, pre pregnancy BMI and gestational diabetes mellitus. Results: There was a statistically significnt difference in the detection rate of overweight and obesity risk among children with different mothers s pre pregnancy BMI ( χ 2=22.85, P <0.05). Linear regression analysis showed that TG levels in late pregnancy were positively related to BMI Z score ( β=0.10, 95%CI=0.02-0.18, P <0.05). Poisson regression with a robust error variance indicated that, compared with the Q 1 group of TC, the Q 4 group of TC in mid pregnancy was associated with an increased risk of overweight and obesity in offspring at 3 years of age ( RR=1.59, 95%CI =1.04-2.44); compared with the Q 1 group of TG, the Q 4 group of TG during late pregnancy increased the risk of overweight and obesity in offspring at 3 years of age ( RR=1.79, 95%CI =1.02-3.12) (both P <0.05). Conclusions Maternal serum TC level during mid pregnancy can increase the risk of overweight and obesity in offspring at 3 years of age. Maternal serum TG levels during late pregnancy is positively correlated with BMI and the risk of overweight and obesity in offspring at 3 years of age.

Objective:To investigate the factors influencing the decision to delivery interval (DDI) in emergency cesarean section in Guangzhou and the impact of DDI on maternal-infant outcomes.Methods:A retrospective study was conducted on clinical data of pregnant women who underwent emergency cesarean section at municipal and district maternal and child health hospitals in Guangzhou city in 2021. Per the classification method of emergency cesarean section and recommendations for DDI provided by National Institute for Health and Clinical Excellence guidelines, these subjects were classified into Category Ⅰ and Category Ⅱ cesarean sections. Each category was further divided into two subgroups based on DDI: the Category Ⅰ group into >30 min and ≤30 min subgroups, and the Category Ⅱ group into >75 min and ≤75 min subgroups. Chi-square test or Fisher's exact test, two independent samples t-test, Mann-Whitney U test, and logistic regression were used to analyze the potential factors influencing DDI and the impact of DDI on maternal-infant outcomes. Results:(1) Totally 502 women underwent urgent cesarean section, including 304 (60.6%) Category Ⅰ and 198 (39.4%) Category Ⅱ, were analyzed. Among the Category Ⅰ group, 30.3% (92/304) achieved a DDI of ≤30 min, while 37.4% (74/198) of Category Ⅱ cases had a DDI of ≤75 min. (2) For the Category Ⅰ cases, multivariate logistic regression showed that more patients under intravertebral anesthesia, than those under general anesthesia, had a DDI >30 min ( OR=14.04, 95% CI: 6.14-32.10) as well as more with ward-based emergencies than those with delivery room emergencies ( OR=3.21, 95% CI: 1.72-6.00, both P=0.001). Among the Category Ⅱ cases, logistic regression revealed that cesarean section during routine working hours was more likely to achieve DDI >75 min than that during resting hours ( OR=3.93, 95% CI: 2.03-7.63, P=0.001). The risk of DDI >75 min was higher in tertiary maternal and child health hospitals compared with secondary maternal and child health hospitals ( OR=2.45, 95% CI: 1.06-5.70, P=0.037). (3) Among the Category Ⅰ cases, compared with the DDI ≤30 min group, the DDI >30 min group had a lower risk of neonatal Apgar score ≤7 at 1 min ( OR=0.31, 95% CI: 0.14-0.69, P=0.004), but there was no significant difference in the risk of neonatal Apgar score ≤7 at 5 min ( OR=0.21, 95% CI: 0.04-1.17) or neonatal asphyxia ( OR=0.32, 95% CI: 0.07-1.44) between the two subgroups. In cases of Category Ⅱ cesarean sections, there was no significant difference in any maternal-infant outcomes between DDI ≤75 min and DDI >75 min subgroups. Conclusions:The location of emergency and types of anesthesia are the influencing factors of DDI for Category Ⅰ cesarean sections, while the operation time and level of maternal and child health hospital are the influencing factors of DDI for Category Ⅱ cesarean sections. We did not find any impact of DDI on maternal or infant outcome.

Objective:To evaluate the detection ability and efficiency of single nucleotide polymorphisms array (SNP-array) and next generation sequencing (NGS) in preimplantation genetic testing (PGT).Methods:Totally 188 couples who carried pathogenic gene mutation and requested preimplantation genetic testing for monogenic (PGT-M) treatment were retrospectively analyzed in the Reproductive Center of Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region during January 2020 and August 2022. After ovulation induction, insemination was conducted by intracytoplasmic sperm injection (ICSI) and cultured in vitro, 995 blastocysts were harvested and biopsied. After whole genome amplification (WGA) of the genetic material from embryonic cell samples, their carrying status of mutations and chromosome copy number variations (CNVs) were analyzed by SNP-array or NGS, respectively, and along with mutation direct detection by Sanger sequencing or Gap-PCR. The relationship between female age and the number of blastocysts was analyzed, as well as the proportion of embryos carrying mutations and pathogenic CNVs. The detection success rate and accuracy of different molecular diagnostic techniques used in PGT were compared. Amniocentesis prenatal diagnosis was performed in the second trimester after successful intrauterine transfer of embryos. Results:1) A total of 924 embryo samples were successfully performed genetic testing, with a total success rate of 92.9%, and 389 embryos (42.1%) can be transferred according to these results. 2) In detecting deletional α-thalassemia, the success rate of Gap-PCR [84.9% (465/548)] was lower than that of SNP-array [98.7% (81/82)] and NGS [92.5% (431/466)]. However, the success rate of direct mutation detection by Sanger sequencing [98.5% (440/447)] was not significantly different from that by SNP-array [95.6% (110/115)] and NGS [96.1% (319/332)]. There were 38 embryo samples with direct mutation detection results inconsistent with those based on SNP haplotyping. In addition, 4 embryo samples failed SNP haplotyping due to chromosomal recombination. 3) Compared with NGS, SNP-array had a lower success rate [83.7% (165/197)] in detecting CNVs, but it could find out more types of chromosomal abnormalities. 4) A total of 152 embryo transfers were performed, 107 patients got clinical pregnancies, 69 patients completed amniocentesis prenatal diagnosis, and 42 healthy infants were delivered.Conclusion:In considering the detection efficiency, SNP-array is suitable for analyzing embryos which carry multiple pathogenic genes, rare monogenic or deletion mutations, whereas NGS is suitable for detecting common types of mutations. Meanwhile, using Sanger sequencing and Gap-PCR to directly detect the mutations can improve the success rate and accuracy of PGT. Our findings would provide a basis for PGT technicians to select appropriate detection platforms based on the type of mutations and the situation of patients.

Objective:To investigate the correlation between different degrees of white matter hyperintensities (WMHs) and outcome after intravenous thrombolysis (IVT) in patients with acute ischemic stroke.Methods:Patients with AIS received intravenous thrombolytic therapy with standard dose of alteplase in the First Hospital of Putian City from January 2019 to June 2022 were retrospectively included. The Fazekas scale was used to score the WMHs shown on MRI, and the patients were divided into without or mild WMH group and moderate-to-severe WMH group. The clinical baseline data and the clinical outcome after 3 months of the two groups were compared. The poor outcome was defined as the modified Rankin scale score >2. Multivariate logistic regression analysis was used to determine the influence of the severity of WMHs on the outcome after intravenous thrombolysis. Results:A total of 103 patients with AIS were included. Their age was 64.85±10.89 years old, and 66 (64.1%) were men. There were 60 patients (58.3%) in the without or mild WMH group, and 43 (41.7%) in the moderate-to-severe WMH group. There were significant differences in age, body mass index, systolic blood pressure, baseline National Institutes of Health Stroke Scale (NIHSS) scores, as well as the proportion of patients with hypertension, smoking, hemorrhagic transformation and poor functional outcome at 3 months after onset in different degrees of WMH groups (all P<0.05). There were 73 patients (70.9%) in the good outcome group and 30 (29.1%) in the poor outcome group. There were significant differences in age, body mass index, baseline NIHSS score, WMH score, as well as the proportion of patients with hypertension, large atherosclerotic stroke and symptomatic intracranial hemorrhage between the two groups ( P<0.05). Multivariate logistic regression analysis showed that after adjusting for confounding factors, moderate-to-severe WMHs were the independent risk factors for the poor outcome at 3 months after intravenous thrombolysis (odds ratio 3.810, 95% confidence interval 1.298-1.124; P=0.015). Conclusion:Moderate-to-severe WMHs are associated with the poor outcome in patients with AIS at 3 months after intravenous thrombolysis.

Objective This study aims to explore the formation of the dilemma of"giving care"for disabled elderly people in nursing homes from the perspective of active health.Methods Purposive sampling was used to select caregivers and disabled elderly people from a nursing home in Chongqing as research subjects from July 2022 to December 2022.One-on-one in-depth interviews were conducted and Colaizzi's 7-step thematic analysis method was employed to collect and analyze the interview data.Results 4 themes were identified:①the dominance of the"giving"care concept,including the cultural thoughts of filial piety,passive acceptance of care characteristics and consumer psychology regarding paid services;②insufficient"participation"care ability,including lack of knowledge regarding active health and a weakening of skills to promote participation;③the hindrance to"transformation"of care models,including objective limitations in terms of human resources and delays in adapting aging environments;and ④the decline in"utilization"of internal abilities,including excessive avoidance of potential risks,a heavy workload of care and poor quality of individual care.Conclusion The formation of the dilemma of"giving care"for disabled elderly people in nursing homes is affected by multiple factors such as social background,service system,supply resources,and management mode.Transforming disabled elderly individuals from a state of"passive giving care"to"active participation in their health"is an important measure to realize the concept of positive aging and healthy aging.

An adult female patient of internal nuclear inclusion disease(NIID)with a major clinical manifestation of decreased intelligence and recurrent disturbance of consciousness was followed up for nearly 4 years.In particular,the evolution of the video-electroencephalogram(VEEG),the auxiliary diagnosis of VEEG,and the prediction value of VEEG for clinical outcome were summarized.We found that(1)the background rhythm in NIID patients evolved with the progression of the disease;(2)electroencephalogram reactivity could predict the outcome of NIID coma;(3)VEEG helped to determine whether the consciousness disturbance caused by NIID was due to non-convulsive status epilepticus,This case provides a new idea to explore the application of VEEG in NIID.

Objective:To explore the obstacle factors and promoting factors of exercise guidance and implementation after breast cancer surgery, so as to provide reference and basis for the formulation of exercise program after breast cancer patients.Methods:Using the objective sampling method, a total of 10 medical staff and 10 patients with breast cancer after operation from the breast surgery department of the Seven People's Hospital Affiliated to Shanghai University of Traditional Chinese Medicine hospital in Shanghai were selected as research objects from July to September 2022. A semi-structured interview was conducted. The interview outline was developed based on the knowledge transformation framework, and the results were analyzed by the content analysis method.Results:The study extracted three levels of influencing factors. The system level included caregiver workload, educational materials, norms and responsibilities and trust in evidence-based evidence. The practitioner level included the level of exercise knowledge, the concern about patient compliance and the emphasis on exercise. The patient level included sports knowledge level, personality and interest, venous line, adverse reaction of treatment, psychological state, weather environment, attention to health and concern of family members.Conclusions:The medical staff need to consider the postoperative exercise guidance for breast cancer patients from the department, themselves and patients, and should fully consider the patients' conditions and subjective experience to improve the patients' exercise compliance.

Nevus-like basal cell carcinoma syndrome (NBCCS) is a rare autosomal dominant disease characterized by the occurrence of multiple maxillofacial keratocysts, basal cell carcinoma, child medulloblastoma, and various skeletal and soft tissue dysplasia. In 2020, a patient with NBCCS dominated by facial basal cell carcinoma was admitted to Xiangya Hospital of Central South University. The patient was an elderly woman. Ten years ago, the systemic mass appeared, especially on the face, but it was not treated. Later, these masses gradually increased in volume and number, and showed invasive properties. The nasal mass was broken and suppurated, seriously affecting the patient's life quality. The patient came to the hospital to improve the symptoms. Staphylococcus aureus and Providencia rettgeri were cultured in the patient's nasal secretions. Nasal sinus enhanced MRI showed that the subcutaneous soft tissue of the right cheek and the anterolateral mucosa of the left nasal cavity were invaded, indicating multiple malignant skin lesions. After admission, local anesthesia was performed and some masses were removed. Pathological examination of the mass showed basal cell carcinoma. After general anesthesia, multiple masses were resected. The postoperative pathological examination showed that multiple basal cell carcinoma invaded the deep dermis near subcutaneous fat layer. Combined with the results of clinical and immunohistochemical examination, the patient was diagnosed as NBCCS. There were no clear tumor thrombus in the vessel and no nerve invasion. No recurrence or new tumor was found after 1 year follow-up. The incidence rate of NBCCS is low and clinical symptoms are different. The patient's life quality is poor and the patient needs long-term individualized treatment.
