Background Anxiety and depression are common perinatal mental health issues that often occur together and can have serious negative effects on both maternal and infant health. Objective To examine the relationships between lifestyle factors and comorbid anxiety and depression (CAD) among pregnant women in Shanghai. Methods The study estimated the prevalence of CAD during the first, second, and third trimesters of pregnancy using the Self-rating Anxiety Scale (SAS) and Center for Epidemiological Studies-Depression (CES-D) based on data from the China National Birth Cohort (CNBC) embryonic-derived diseases with assisted reproductive technology (ART) sub-cohort. Information on demographics, sleep status, nutritional intake, and exercise during each trimester was collected through self-made questionnaires, the Pittsburgh Sleep Quality Index (PSQI), and the Food Frequency Questionnaire (FFQ). Lifestyle factors (such as sleep status, nutritional intake, and exercise during each trimester) were analyzed using logistic regression and generalized linear mixed models (GLMM) to determine their impacts on the prevalence of CAD (yes or no) among pregnant women. Results A total of 2876 pregnant women were included in this study. The prevalence of CAD was 10.6% (305), 3.6% (103), and 5.5% (159) in the first, second, and third trimesters of pregnancy, respectively. The logistic regression analysis revealed that poor sleep quality throughout the entire pregnancy were statistically associated with an increased prevalence of CAD, and the odds ratios (OR) with 95% confidence intervals (CI) were 2.817 (1.845, 4.301), 2.840 (1.855, 4.347), and 9.316 (5.835, 14.876) for the first, second, and third trimesters, respectively, when compared to good sleep quality. Additionally, compared to an intake frequency of 7 times per week, the frequency of egg intake ≤3 times per week in the first trimester (OR=2.025, 95%CI: 1.197, 3.425) and the frequency of egg intake of 4–6 times per week (OR=1.896, 95%CI: 1.117, 3.216) or ≤3 times per week (OR=1.906, 95%CI: 1.082, 3.357) in the third trimester were associated with an increased risk of CAD (P<0.05). Moreover, when compared to a frequency of exercise >3 times per week, never or almost never exercising in the second trimester (OR=2.218, 95%CI: 1.220, 4.035) was associated with an increased risk of CAD (P<0.05). The GLMM analysis also demonstrated a significant association between poor sleep quality, lower exercise frequency, or lower intake frequency of vegetables, eggs, or milk and an increased risk of CAD (P<0.05). Conclusion The prevalence of CAD among pregnant women in Shanghai follows a U-shaped distribution, with the highest rate occurring in early pregnancy and the lowest rate in mid-pregnancy. Factors such as poor sleep quality, inadequate intake of vegetables, eggs, or milk, and lack of exercise during pregnancy may increase the risk of CAD. Implementing lifestyle interventions during pregnancy could potentially reduce the risk of mental health problems and improve the overall health of both mothers and babies.

AIM:To investigate the mechanism through which esculetin induces ferroptosis of mouse breast cancer 4T1 cells.METHODS:Molecular docking of esculetin with p53,solute carrier family 7 member 11(SLC7A11)and glutathione peroxidase 4(GPX4)proteins was performed,and Kaplan-Meier curves and time-dependent receiver oper-ating characteristic curves were drawn.The 4T1 cells were divided into 6 groups,namely the control(CON),1/2 IC50,IC50,2 IC50,erastin,and capecitabine groups.The appropriate drug concentration for treating 4T1 cells was screened by CCK-8 assay.The invasion and migration abilities of 4T1 cells following esculetin treatment at the selected drug concentra-tion were analyzed by scratch test and Transwell assay.Mitochondrial morphological change were examined by electron mi-croscopy.The levels of ferroptotic cell death were then quantified by Fe2+,reactive oxygen species(ROS),malondialde-hyde(MDA),glutathione(GSH),and GPX4 assays.Western blot was performed to evaluate the protein levels of p53,SLC7A11,GPX4 and acyl-CoA synthetase long-chain family member 4(ACSL4).RESULTS:Compared with CON group,the esculetin 1/2 IC50,IC50 and 2 IC50 groups showed smaller size,increased membrane density,and decreased ridge of mitochodria,as well as decreased levels of GSH and GPX4,reduced cell invasion and migration abilities,and de-creased levels of SLC7A11 and GPX4 proteins(P＜0.05).Furthermore,these groups exhibited increased levels of Fe2+,ROS,and MDA,as well as elevated p53 and ACSL4 protein abundance(P＜0.05).CONCLUSION:Esculetin pro-motes ferroptosis of 4T1 cells through a mechanism involving the p53/SLC7A11/GPX4 regulatory axis.

Objective To observe the effects of Angelicae Sinensis Radix-Paeoniae Radix alba combined with bone marrow mesenchymal stem cells(BM-MSCs)transplantation on liver inflammation and hepatocytes regeneration in non-alcoholic steatohepatitis(NASH)associated cirrhosis;To discuss its possible mechanism.Methods West diet combined with carbon tetrachloride was used to prepare the NASH related cirrhosis model.The mice were randomly divided into control group,model group,Angelicae Sinensis Radix-Paeoniae Radix alba group,BM-MSCs group,and Angelicae Sinensis Radix-Paeoniae Radix alba+BM-MSCs group,with 12 mice in each group.After successful modeling,corresponding interventions were given according to grouping for 4 consecutive weeks.HE staining was used to observe the morphology of liver tissue;the contents of serum ALT,AST,TBil,TG,ALB,AFP,as well as the contents of IL-1β,TNF-α and HGF in liver tissue were detected;RT-qPCR was used to detect TLR9,MyD88,TRAF6 and NF-κBp65 mRNA expression in liver cells;primary liver cells were separated,CpG ODN 2216 stimulation was induced in vitro,cells supernatant was extracted,and IL-1β and TNF-α content were detected.Results Compared with the control group,inflammatory cell infiltrated in liver tissue of model group mice,accompanied by hepatocyte necrosis and collagen deposition,forming pseudo lobules;the contents of serum ALT,AST,TBil and TG increased,the content of ALB decreased,the content of HGF in liver tissue decreased,the contents of IL-1β and TNF-α increased,with statistical significance(P<0.05);the mRNA expressions of TLR9,MyD88,TRAF6 and NF-κBp65 in liver cells increased(P<0.05),and the contents of IL-1β and TNF-α in cells supernatant increased after CpG ODN 2216 induction(P<0.05).Compared with the model group,the inflammatory infiltration in liver tissue and necrosis of liver cells were reduced and the degree of liver fibrosis was alleviated in the Angelicae Sinensis Radix-Paeoniae Radix alba+BM-MSCs group,the liver tissue damage in Angelicae Sinensis Radix-Paeoniae Radix alba group and BM-MSCs group were slightly improved;except for the TG content in BM-MSCs group,all detection indicators showed significant improvement in each intervention group(P<0.05).Compared with the Angelicae Sinensis Radix-Paeoniae Radix alba group and BM-MSCs group,the Angelicae Sinensis Radix-Paeoniae Radix alba+BM-MSCs group showed statistical significance in related detection indicators(P<0.05),and demonstrated a synergistic effect.Conclusion Angelicae Sinensis Radix-Paeoniae Radix alba combined with BM-MSCs transplantation could effectively improve the liver function and promote liver cell regeneration.The mechanism is associated with the down-regulation of TLR9/NF-κB signaling pathway expressions and function,the inhibition of inflammatory cytokines secretions,and the improvement of liver inflammatory microenviroment.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Objective To investigate the prevalence of allergic and infectious diseases in children， and to assess the influence of indoor and outdoor environmental factors on these two common diseases in children. Methods A questionnaire was used to investigate the prevalence of allergic and infectious diseases in 140 children of 7 years old in Laizhou Bay， Shandong Province. Logistic regression was used to analyze the associations between indoor and outdoor environmental factors and children’s allergic and infectious diseases， respectively. Results The prevalence of previous eczema and other allergic diseases for the past year in children was 37.9% and 15.0%， respectively， and the prevalence of infectious diseases for the past year was 35.7%. As for allergic diseases， eye irritation due to outdoor air （ OR =2.977； 95% CI ： 1.407‒6.296） and nose irritation due to outdoor air （ OR =5.147； 95% CI ： 1.272‒20.827） were the risk factors for previous eczema in children. Indoor musty taste increased the risks of urticaria （ OR =4.306； 95% CI ： 1.062‒17.454） and previous eczema （ OR =3.853； 95% CI ： 1.080‒13.743）. The use of cockroach killers indoors increased the risk of rhinitis （ OR =6.102； 95% CI ：1.297‒28.697）. As for infectious diseases， having outdoor pollution sources increased the risk of gastrointestinal infection （ OR =4.937； 95% CI ： 1.050‒23.216）， and the use of mosquito coils and clothing mothproofing agents increased the risks of respiratory （ OR =6.333； 95% CI ： 1.397‒28.714） and gastrointestinal infections （ OR =3.218； 95% CI ： 1.074‒9.644）， respectively. However， we did not find associations between indoor passive smoking and allergic or infectious diseases. Conclusion Except outdoor passive smoking， all the other indoor and outdoor environmental factors increase the risks of children’s allergies and infectious diseases.

ObjectiveTo investigate the changes of surface electromyography (sEMG) of the flexors and extensors of the affected fingers after manual digitorum sensory stimulation (MDSS) in the hemiplegic patients after stroke. MethodsFrom April to August, 2020, 50 stroke patients in Department of Rehabilitation Medicine, the Second Hospital of Anhui Medical University accepted MDSS on the nail beds and the third knuckles of affected fingers, until the fingers extended actively. The tension of affected flexor pollicis brevis, flexor digitorum superficialis and extensor digitorum were assessed with modified Ashworth Scale (MAS) before and immediately after stimulation; while the root mean square (RMS) of sEMG of bilateral flexor pollicis brevis, flexor digitorum superficialis and extensor digitorum were recorded. ResultsThe MAS score of all the muscles decreased after stimulation (|Z| > 2.699, P < 0.01), while the RMS of affected extensor digitorum increased (t = -2.069, P < 0.05). Compared with the unaffected ones, RMS of affected flexor pollicis brevis and extensor digitorum decreased before and after stimulation (t > 2.450, P < 0.05). ConclusionMDSS may immediately relieve the spasm of flexors of hemiplegic fingers after stroke, which associates with the promoting muscle strength of the extensors.

Background Heavy metals are widely present in the environment, difficult to degrade, and bioaccumulative. Children's physical development are not mature, and exposure to heavy metals which may cause irreversible harm to them. However, the current research conclusions are still inconsistent. Therefore, it is very important to pay attention to the impact of heavy metal pollutants on physical development. Objective To detect the level of heavy metal exposure of school-age children in Laizhou Wan, Shandong Province, and to explore the relationship between heavy metal exposure level and physical development indexes of school-age children. Methods The subjects of this study were 318 children born to pregnant women recruited from Laizhou Wan Birth Cohort in Shandong Province from September 2010 to December 2013. The school-age children at age 7 were followed up from July to September 2019. Their urine samples were collected and the levels of arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) in urine were detected by inductively coupled plasma mass spectrometry (ICP-MS). At the same time, the height, weight, body mass index (BMI), waist circumference, and body fat percentage of the children were evaluate to analyze the relationship between the four heavy metals in children's urine and the indicators related to children's physical development. Results Among the 318 school-age children with an age (\begin{document}$\bar x \pm s $\end{document}) of (7.77±0.67) years, the median (P₂₅, P₇₅) levels of As, Cd, Pb, and Hg in urine were 73.98 (44.81, 124.61), 0.40 (0.27, 0.58), 1.20 (0.71, 1.72), and 2.38 (1.32, 4.80) µg·g⁻¹ (of creatinine), respectively. The children’s urinary Cd level was positively correlated with their weight, BMI, and waist circumference (P<0.05), and corresponding regression coefficients (b) and its 95% confidence intervals (CI) were 0.99 (0.14-1.83), 0.43 (0.06-0.81), and 1.35 (0.27-2.42), respectively; while the other heavy metals were not related to the above physical development indicators (P>0.05). After sex stratification, it was found that boys’ urinary Cd level was positively correlated with their height, weight, BMI, and waist circumference (P <0.05) with associated b (95%CI) of 1.73 (0.53-2.93), 2.03 (0.60-3.47), 0.75 (0.11-1.38), and 2.66 (0.85-4.47), respectively; such associations were not found in girls. After further stratification of boys’ BMI according to normal, overweight, and obesity, it was found that a higher urinary Cd level was correlated with an increased risk of obesity in boys (P<0.05), and the associated b (95%CI) was 2.34 (1.02-5.36). Conclusion The level of urinary Cd exposure of boys in Laizhou Wan, Shandong Province is positively correlated with their height, weight, BMI, and waist circumference, and may be related to obesity in boys.

Background Exercise during pregnancy is closely related to maternal and infant health. Previous studies in developed countries have linked maternal exercise during pregnancy with newborn body weight as well as subcutaneous fat thickness. However, the relevant studies in China are limited, and the conclusions remain inconsistent. Objective To investigate the effects of maternal exercise during pregnancy on neonatal weight and subcutaneous fat thickness. Methods Based on the Shanghai Birth Cohort, 959 maternal-infant pairs were included in this study. The International Physical Activity Questionnaire was used to collect average weekly frequency and daily minutes of walking in the first and second trimesters, and entropy weight method was used to calculate the cumulative exercise index in the two trimesters. Birth weight was measured using a calibrated weigh scale. Subcutaneous fat thickness was measured at abdomen, scapula, and triceps with a Harpenden skinfold caliper for all newborns and the sum of the thickness for the three sites was then calculated. A multiple linear regression model was employed to estimate the relationships of cumulative exercise index during pregnancy with neonatal body weight and subcutaneous fat thickness. Subgroup analyses stratified by pre-pregnancy body mass index (BMI) and sex of newborns were also performed. Results The mean age of pregnant women was (28.5±3.8) years, and the pre-pregnancy BMI was (21.4±3.0) kg·m⁻². Newborn boys were slightly more than newborn girls (54.3% vs 45.7%), and the neonatal weight was (3374.0±427.5) g. The means of newborns' abdominal, scapular, and triceps subcutaneous fat thickness were (4.4±1.3), (5.4±1.4), and (6.0±1.5) mm, respectively, and the sum of subcutaneous fat thickness was (15.8±3.9) mm. In the first and second trimesters, 77.3% and 88.7% of pregnant women walked 4 d per week and more, respectively; the daily minutes of walking was (36.9±27.2) min and (43.3±26.3) min, respectively; the cumulative exercise index was 25.6±17.7 and 35.9±21.1, respectively. The results of multiple linear regression analysis showed that the cumulative exercise index in the second trimester was negatively associated with newborns' abdominal (b=−0.006, 95%CI: −0.010-−0.003), scapular (b=−0.005, 95%CI: −0.009-−0.002), triceps (b=−0.006, 95%CI: −0.010-−0.002), and their sum of (b=−0.018, 95%CI: −0.028-−0.007) subcutaneous fat thickness (P<0.05); in the first and second trimesters, however, the relationship between maternal cumulative exercise and newborns' body weight was not significant. The results of stratified analyses showed that the negative associations between maternal cumulative exercise index and newborns' subcutaneous fat thickness for the second trimester remained significant in the subgroups of boys and neonates whose mothers had normal pre-pregnancy BMI (P<0.05). Conclusion Cumulative exercise index in the second trimester is negatively correlated with the neonatal thickness of subcutaneous fat, and the association may be altered by neonatal sexes and maternal pre-pregnancy BMI levels.

Objective:To explore the feasibility and clinical effects of using free thinned deep inferior epigastric artery perforator flap to repair extensive soft tissue defects in extremities.Methods:From April 2010 to January 2014, 12 patients with extensive soft tissue defect in extremities after trauma, including 10 males and 2 females, aged 21 to 48 years, 6 patients with defect in the back of wrist and 6 patients with defect in ankle were admitted to the Department of Bone Microsurgery of Xi′an Honghui hospital. After debridement, the size of soft tissue defect ranged from 15.0 cm×4.5 cm to 28.0 cm×11.0 cm. The free thinned deep inferior epigastric artery perforator flap was designed, cut and transferred for reconstruction, with size of 15.0 cm×5.0 cm to 29.0 cm×12.0 cm. The flap thickness ranged from 4.0 to 6.5 cm before defatting, and was 0.6 to 0.9 cm after defatting. All the donor sites of flaps were closed directly by suturing. The flap survival and the appearance and function of flap and donor site were observed during follow-up.Results:All the flaps survived smoothly after surgery. During follow-up of 10 to 42 months, the flaps showed no bloat in appearance, no further flap revision or defatting procedures were required, the distance of static 2-point discrimination was 11 to 17 mm (14.5 mm on average). The abdominal function of patients was not affected, and no postoperative abdomen hernia or ulceration was noted.Conclusions:The free thinned deep inferior epigastric artery perforator flap is thin and suitable for repairing extensive soft tissue defects in extremities with very good outcomes.
