This article systematically analyzed the historical evolution of the origin， scientific name， producing area， quality evaluation， harvesting and processing， and other aspects of Quisqualis Fructus by consulting the ancient materia medica， medical books， prescription books， local literature and combining with the modern literature and standards， summarized and explored the development rules of its medicinal properties and efficacy along with their underlying causes， in order to provide support for the development and utilization of famous classical formulas containing this herb. According to the textual research， Shijunzi was first recorded as Liuqiuzi in Nanfang Caomuzhuang of the Jin dynasty， and the name of Shijunzi was first used in Kaibao Bencao of the Song dynasty， which has been consistently used throughout subsequent dynasties， and there were also aliases such as Junziren， Sijunzi， and Dujilizi. The mainstream source of Quisqualis Fructus used in the past dynasties has been the dried mature fruits of Quisqualis indica， a plant belonging to the family Combretaceae. In modern times， its variety Q. indica var. villosa has also been recorded as the medicinal material of Quisqualis Fructus. In 2007， the Flora of China（English edition） designated Q. indica var. villosa as a synonym of Q. indica. Today， the accepted name of Shijunzi is updated to Combretum indicum. According to ancient herbal records， the producing areas of Quisqualis Fructus were Guangdong， Hong Kong， Macao， Guangxi， Hainan， Sichuan and Fujian， and then gradually expanded to Yunnan， Taiwan， Jiangxi and Guizhou. Since the Song dynasty， two major production regions have gradually emerged in Sichuan， Chongqing and Fujian. Currently， it is primarily cultivated in Chongqing， Guangxi and other areas， with Chongqing yielding the highest output. Since modern times， superior quality has been defined by large size， a purple-black surface， plump grains， and a yellowish-white kernel. According to ancient herbal records， the harvesting period of Quisqualis Fructus was the July and August of the lunar calendar， mostly used raw after shelling or with the shell intact， it underwent processing methods such as cleaning， slicing， mixing， steaming， roasting， stewing， and frying. Currently， the harvesting period is autumn， followed by sun-drying or low-heat drying， with processing methods including cleaning， stir-frying， and stewing. In ancient and modern literature， the records of the properties， functions and indications of Quisqualis Fructus are basically the same， that is， sweet in taste， warm in nature， predominantly non-toxic， belonging to the spleen and stomach meridians. It possesses effects of insecticide， decontamination and invigorating spleen for ascariasis， enterobiasis， abdominal pain due to worm accumulation and infantile malnutrition.The contraindications for use primarily include avoiding consumption by individuals without parasitic infestations， limiting use for those with spleen-stomach deficiency-cold， refraining from drinking hot tea during medication， and avoiding excessive intake. Based on the textual research， it is suggested that the dried mature fruits of Q. indica should be used as the medicinal material for the development of famous classical formulas containing Quisqualis Fructus. Processing methods may be chosen according to prescription requirements， and the raw products is recommended for medicinal use if not specified.

ObjectiveTo optimize the technical parameters of mouse embryo transfer (including oviduct opening method, pseudopregnant recipient body weight, number of embryos transferred per recipient, and unilateral vs. bilateral oviduct transfer), improve the efficiency of embryo transfer (the pregnancy rate of recipient female mice after embryo transfer is used as the evaluation index), and improve the utilization rate of high-quality embryo germplasm resources (the birth rate of mice after embryo transfer is used as the evaluation index). Methods560 SPF-grade ICR mice and 440 C57BL/6J mice were used as experimental animals. 2-cell embryos were obtained through in vitro fertilization. A single-factor controlled variable method was used to systematically investigate the effects of four factors, including oviduct opening method, pseudopregnant recipient body weight, number of embryos transferred per recipient, and unilateral vs. bilateral oviduct transfer, on the pregnancy rate and birth rate of mouse embryo transfer. ResultsThe pregnancy rate of recipients with an opening made in the oviduct using a 26G syringe needle reached 90%, which was significantly higher than the 43% in the group with oviduct openings cut by Vannas scissors (P<0.05). Pseudopregnant recipients weighing 29-35 g exhibited optimal embryo transfer outcomes, with a pregnancy rate of 90% and a birth rate of 44%, and no pups were crushed by the recipient mothers. The highest birth rate of 42% was observed in the group receiving 16-25 embryos per recipient. Transferring 26-35 embryos per recipient achieved a 90% pregnancy rate and maximized embryo utilization efficiency. However, transfer efficiency decreased significantly when more than 35 embryos were transferred. Transfer of 24-26 embryos per recipient balanced relatively high pregnancy and birth rates. Bilateral oviduct transfer of mouse embryos yielded slightly higher pregnancy and birth rates than unilateral transfer, but the difference was not statistically significant (P>0.05). ConclusionSelecting pseudopregnant recipient female mice weighing 29-35 g, using a 26G syringe needle to make an opening in the oviduct, and controlling the number of transferred embryos at 24-26 per recipient can effectively improve the success rate of embryo transfer and achieve efficient utilization of high-quality embryo germplasm resources.

Objective To explore the ^“contribution^” of different exposures to cardiovascular diseases at the population level and to construct a risk prediction model for the effective allocation of prevention resources. Methods The CHNS (China Health and Nutrition Survey) database was used. In 2009, 2011 and 2015, 9 899 permanent residents aged 35 to 75 years in 10 provinces and cities in the central and eastern regions (Beijing, Liaoning, Heilongjiang, Shanghai, Shandong, Henan, Hubei, Hunan, Guangxi and Jiangsu) were selected as the research subjects. A single-factor analysis was conducted to examine the risk factors including sex, age, BMI, marital status, urban/rural area, sleep time, smoking, alcohol consumption, diabetes, education, and health insurance. The multifactor-adjusted population-attributable risk of certain risk factors was also estimated based on logistic regression analysis. The cardiovascular disease (CVD) risk prediction model was developed using a modeling group of 6 927 randomly selected individuals (70%) and a validation group of 2 974 individuals (30%). The model's differentiation and calibration were assessed using the receiver operating characteristic (ROC) curve and the Hosmer-Lemeshow goodness-of-fit test. Results The results showed that the adjusted population attributable risk and 95% confidence interval for BMI, sleep time, smoking, drinking and diabetes were 32.20% (27.67%-36.89%), 7.90% (1.68%-16.58%), 18.56% (11.35%-26.24%), 6.47% (0.11%-13.25%) and 5.73% (4.42%-7.03%). The results of multivariate adjusted population attributable risk percentage showed that BMI was the dominant cause of cardiovascular diseases, followed by smoking, sleep time, drinking and diabetes. The low-risk prevalence rate was 18.44%, the higher-risk prevalence rate was 14.19%, and the high-risk prevalence rate was 42.52%. The area under ROC curve AUC was 0.711, P<0.001, and Hosmer-Lemeshow goodness of fit test showed P=0.257. Conclusion In the future, it is important to focus on high-risk groups , control body mass index to the normal range, and reduce smoking , which is of great significance for the prevention of cardiovascular diseases. The risk prediction model has the value of good differentiation and practicability , and can provide certain prediction ability for the prevention of cardiovascular diseases.

Finnish school meal services are not only free of charge, nutritionally balanced, safe and hygienic, but also carry the educational function of edutainment in meals. In order to ensure the high quality and efficient operation of the school meal service system, Finland has built a horizontal collaborative governance model, that is, the departments of education, finance, health and quality inspection have a clear division of labor and respective responsibilities. China can learn from the experience of Finnish schools in meal services, strengthen financial and legal guarantees, develop the educational functions of school meal services, and make full use of information technology such as the Internet, the Internet of things, and big data to promote the high quality development of school meal services.

Objective To investigate the effect of propofol(Pro)regulating macrophage polari-zation on airway inflammatory response and Toll-like receptor 4-NOD-like receptor protein 3(TLR4-NLRP3)pathway in mice with bronchial asthma(BA).Methods Forty BA model mice were ran-domly divided into BA group,low-dose Pro(Pro-L)group,high-dose Pro(Pro-H)group,and Pro-H+lipopolysaccharide(LPS)group,with 10 mice in each group.Additionally,10 normal mice were included as control group.Lung function indicators[peak expiratory flow(PEF)and ventilation vol-ume(VE)],eosinophil(EOS),lymphocyte(LYM)and neutrophil(NEU)counts in bronchoalve-olar lavage fluid,and interleukin(IL)-4,IL-10,IL-5 and IL-13 levels were measured in each group;flow cytometry was used to detect M1 and M2 macrophage levels and the proportions of T helper(Th)1 and Th 2 cells in peripheral blood;the enzyme-linked immunosorbent assay(ELISA)was used to detect serum interferon-γ(IFN-γ)and immunoglobulin E(IgE)levels;the hematoxylin-e-osin(HE)staining was used to observe the pathological morphology of lung tissues;the Western blot was used to detect the protein expression of cleaved caspase-3,TLR4,NLRP3 and Caspase-1 in lung tissues.Results Compared with the control group,mice in the BA group showed significant lung tissue damage,decreased PEF,VE,IL-10 and M1 macrophage levels,Th1 cell proportion,and IFN-γ level,and significant increased EOS,LYM,NEU counts,IL-4,IL-5,IL-13 and M2 macrophage levels,Th2 cell proportion,IgE,cleaved caspase-3,TLR4,NLRP3,and Caspase-1 protein expression levels(P＜0.05).Compared with the BA group,mice in the Pro-L and Pro-H groups showed significant lung tissue damage,increased PEF,VE,IL-10 and M1 macrophage lev-els,Th1 cell proportion,and IFN-γ level,and significant decreased EOS,LYM,NEU counts,IL-4,IL-5,IL-13 and M2 macrophage levels,Th2 cell proportion,IgE,cleaved caspase-3,TLR4,NLRP3,and Caspase-1 protein expression levels(P＜0.05).LPS significantly attenuated the im-provement effect of Pro in BA mice(P＜0.05).Conclusion Pro may regulate macrophage polari-zation and immune response in BA mice by inhibiting the TLR4-NLRP3 signaling pathway,reducing the degree of inflammatory response,and improving lung tissue morphology and lung function.

ObjectiveTo understand the seropositivity of neutralizing antibodies (NAb) and low-level NAb against SARS-CoV-2 infection in the community residents, and to explore the impact of COVID-19 vaccination and SARS-CoV-2 infection on the levels of NAb in human serum. MethodsOn the ground of surveillance cohort for acute infectious diseases in community populations in Shanghai, a proportional stratified sampling method was used to enroll the subjects at a 20% proportion for each age group (0‒14, 15‒24, 25‒59, and ≥60 years old). Blood samples collection and serum SARS-CoV-2 NAb concentration testing were conducted from March to April 2023. Low-level NAb were defined as below the 25^th percentile of NAb. ResultsA total of 2 230 participants were included, the positive rate of NAb was 97.58%, and the proportion of low-level NAb was 25.02% (558/2 230). Multivariate logistic regression analysis indicated that age, infection history and vaccination status were correlated with low-level NAb (all P<0.05). Individuals aged 60 years and above had the highest risk of low-level NAb. There was a statistically significant interaction between booster vaccination and one single infection (aOR=0.38, 95%CI: 0.19‒0.77). Compared to individuals without vaccination, among individuals infected with SARS-CoV-2 once, both primary immunization (aOR=0.23, 95%CI: 0.16‒0.35) and booster immunization (aOR=0.12, 95%CI: 0.08‒0.17) significantly reduced the risk of low-level NAb; among individuals without infections, only booster immunization (aOR=0.28, 95%CI: 0.14‒0.52) showed a negative correlation with the risk of low-level NAb. ConclusionsThe population aged 60 and above had the highest risk of low-level NAb. Regardless of infection history, a booster immunization could reduce the risk of low-level NAb. It is recommended that eligible individuals , especially the elderly, should get vaccinated in a timely manner to exert the protective role of NAb.

Objective: To systematically evaluate the association between maternal adverse childhood experiences (ACEs) and offspring social behavior, so as to provide a theoretical basis for further research on intergenerational social behavioral development. Methods: Relevant research literature about maternal ACEs and the development of children s maladaptive social behaviors were collected, from China National Knowledge Infrastructure (CNKI), VIP, Wanfang, SinoMed, PubMed, Web of Science, Cochrane Library, Embase and SpringLink databases, covering the period from the inception of each database to May 2025. The Chinese database matched and searched through three groups of keywords: "Pregnant women" "Mothers" and "Women"; "Bad childhood experience" "Bad early experience" and "Bad adolescent experience"; "Children" "Teenagers" "Children s behavior" "Children s development" "Teenagers behavior" "Internalized behavior" and "Externalized behavior". The English database was searched by three groups of keywords: "Female" "Pregnant women" "Mothers"; "Adverse childhood experiences" "Adverse early childhood experiences" "Adverse experiences of adolescent"; "Child behavior" "Child development" "Adolescent behavior" "Internalized behaviors" "Externalized behaviors". The selected literature was evaluated for quality and data extraction, with OR and 95% CI as effect indicators. Stata 16.0 software was used for heterogeneity testing, subgroup analysis, and publication bias analysis. Results: A total of 14 studies involving 64 302 mother-child pairs were included. The Meta analysis results showed a significant correlation between maternal ACEs and both offspring maladaptive internalized behaviors ( OR=1.75, 95%CI=1.42-2.15, P <0.01) and externalized behaviors ( OR=1.82, 95%CI=1.51-2.20, P <0.01). The results of subgroup analyses showed that in different regions[internalized behaviors:domestic, foreign OR (95% CI )=2.03(1.49-2.76), 1.55(1.19-2.03); externalized behaviors: domestic, foreign OR (95% CI )=2.41(1.52-3.82), 1.65(1.36-2.01)], study type[internalized behaviors: cohort study, cross sectional study OR (95% CI )=1.64(1.34-2.00), 1.85(1.30-2.65); externalized behaviors: cohort study, cross sectional study OR (95% CI )=1.76(1.46-2.12), 2.12(1.40-3.20)], sample size [internalized behaviors: ≥4 000, <4 000 pairs OR (95% CI )=1.69(1.13-2.55), 1.77( 1.41 -2.24); externalized behaviors: ≥3 000, <3 000 pairs OR (95% CI )=1.72(1.37-2.17), 2.13(1.44-3.15)], there were significant and positive association between mothers ACEs and children s internalizing and externalizing behaviors (all P <0.05). Conclusion A substantial positive association exists between maternal ACEs and the development of offspring maladaptive internalized and externalized behaviors, but the result needs to be continued to be validated by more research.

Objective To investigate the safety and feasibility of two-port laparoscopic full layer circular closure of the hernia ring for direct inguinal hernia.Methods Between September 2019 and February 2024,9 cases of pediatric indirect inguinal hernia were found to be accompanied by an occult direct inguinal hernia on the right side during two-port laparoscopic inner ring closure.After completing the high ligation of the indirect hernia under laparoscopic monitoring,the bottom of the direct hernia sac was investigated.The needle was held and inserted sequentially from the 4 o'clock direction,crossing the abdominal wall muscle layer through the peritoneum to the subcutaneous layer,and exited at the 8 o'clock direction.The same method was conducted from the 8 o'clock direction in and at the 12 o'clock direction out,and afterwards from the 12 o'clock direction in and at the 16 o'clock direction out(near the previous 4 o'clock insertion point),followed by knotting and closure of the hernia ring.Results Postoperative diagnosis indicated 3 cases of Pantalon hernia(right indirect hernia+right direct hernia)and 6 cases of left indirect hernia+right direct hernia.No extraperitoneal lipoma was found outside the hernia sac.Two-port laparoscopic high ligation of the indirect hernia and laparoscopic circular closure through muscle layer to subcutaneous layer of abdominal wall around the hernia ring was carried out.The operation time was(32.5±3.5)min,and blood loss was less than 1 ml.No intraoperative complications were seen.All the patients were discharged within 6 h after surgery and followed up for 5-13 months(mean,8 months),with 3 cases followed up for more than 12 months.No complications such as incision infection,recurrent hernia,hydrocele,iatrogenic cryptorchidism or testicular atrophy was found.Ultrasound examination of the direct hernia triangular area showed uniform thickness of the abdominal wall and no localized defects observed.Conclusions Laparoscopic circular closure through muscle layer to subcutaneous layer of abdominal wall around the hernia ring is safe and feasible.This procedure supplements the pediatric direct inguinal hernia repair procedure by suturing and closing both peritoneum and abdominal wall muscle layer of direct hernia defect without changing the normal anatomical position of the umbilical fold.

Objectives:To investigate the effect of non-optimal temperature exposure during pregnancy on the risk for preterm birth and identify the susceptible exposure window. At the same time, the interaction between non-optimal temperature and pollutants exposure during pregnancy on preterm birth was analyzed, in order to provide strong clues for the influence of non-optimal temperature exposure during pregnancy on the risk for preterm birth.Methods:A total of 1 852 pregnant women were recruited from September 2021 to June 2023 in Fujian Provincial Maternal and Child Health Care Center. Questionnaire survey was conducted, and their health records were analyzed. The permanent address of each pregnant woman was matched with Fifth Generation European Centre for Medium-Range Weather Forecasts Atmospheric Reanalysis of the Global Climate and a geo-statistical combination model based on satellite remote sensing data collection, then follow-up for pregnancy outcome was conducted. Distributed lag nonlinear model was used to assess the association between exposure to non-optimal temperature during pregnancy and the risk for preterm birth and a multiplicative interaction model was used to assess the interaction between exposure to pollutants and non-optimal temperatures during pregnancy on the risk for preterm birth.Results:After adjusting for potential confounders such as maternal age, occupation, Gross Domestic Product of the region, pre-pregnancy preconception BMI, newborn sex, the weekly susceptibility windows of extreme low temperature ( P1, P3, P5) were week 1-22 , and the weekly susceptibility windows of extreme high temperature ( P95, P97, P99) were week 27 and week 32-36. Extreme low temperature [ P1 ( OR=1.147, 95% CI: 1.041-1.265), P5 ( OR=1.284, 95% CI: 1.035-1.501)] and extreme high temperature [ P97 ( OR=1.146, 95% CI: 1.039-1.263), P99 ( OR=1.216, 95% CI: 1.099-1.345)] exhibited multiplicative interaction with PM 2.5. Conclusions:Exposure to non-optimal temperature during pregnancy was associated with an increased risk for preterm birth. The susceptible exposure windows of extreme low temperature were mainly in early and mid-pregnancy, and the susceptible exposure windows of extreme high temperature were mainly in late-pregnancy. Exposure to non-optimal temperatures and pollutants during pregnancy was associated with an increased risk for preterm birth.
