Objective: To analyze the correlation between preschool children s emotional competence and home rearing environment in Shangrao City, so as to provide support for improving children s emotional competence development as well as their home rearing environment. Methods: A total of 1 242 children aged 3-6 years old from 10 kindergartens in Shangrao City were retrospectively investigated by stratified cluster random sampling method in December 2022, and the Children s Emotional Adjustment Scale-Preschool Version (CEAS-P) and the Home Nurture Environment Scale for children aged 3-6 were surveyed on parents of preschool children. The t-test was used to test the difference, Spearman correlation analysis and multiple linear regression were used to analyze the influencing factors of preschool children s emotional competence. Results: There were significant differences in emotional competence scores of preschool children for demographic indicators including age, place of residence, health status and whether they were only children ( F/t =5.98, 6.56, 38.00, 2.23, P <0.01). The emotional competence of preschool children was positively correlated with the home rearing environment ( r=0.62, P <0.01). Multiple linear regression analysis showed that diverse activities/play participation, social adaptation/self management, and emotional warmth/self expression in home rearing environment were positive predictors of children s emotional ability ( β =0.30, 0.28, 0.16), while neglect/intervention/punishment were negative predictors ( β =-0.09)( P <0.05). Conclusions The home rearing environment is a factor related to young children s emotional competence. It is suggested specific parenting initiatives such as enriching family activities and play, strengthening children s self adaptation and management, giving warmth and let children express emotions, and preventing child neglect, interference and punishment should be conducted to improve children s emotional competence.

ObjectiveTo genotype Oncomelania hupensis， based on microsatellites， in different snail-bearing environments in Jiaxing City， Zhejiang Province， for population genetics analysis in order to explore the reasons and influencing factors for the existence or proliferation of snails and to provide scientific basis for effective monitoring and control of snails. MethodsA total of 90 snail samples from three populations were collected in Yaobang Village （YB） and Sanxing Village （SX） in Pinghu City， and Yunhe Farm （YH） in Xiuzhou District， all were selected for snail checking in key snail habitats of Jiaxing City in 2022. DNA of the snails was genotyped and analyzed for population genetics using nine microsatellite loci. ResultsA total of 84 alleles were observed， and the mean number of alleles （Na） was 7.889， 5.667， and 3.778 for YB， SX， and YH respectively； the number of effective alleles （NeA） was 4.807， 3.329， and 2.294， respectively； and the coefficients of inbreeding （F_IS） were 0.400， 0.377， and 0.493， respectively. Under the Infinite Allele Model （IAM）， the SX and YH might have a recent bottleneck. The NEstimator and LDNe software calculated effective population sizes （Ne） were above 31.9. AMOVA analysis showed that the variation of snails in the three populations mainly existed among individuals， accounting for 41.4% of the total variation. The value of the index of genetic differentiation between populations （F_ST） was 0.286， indicating a high degree of genetic differentiation. The results of the principal component analysis and phylogenetic tree were consistent， and the three populations were divided into two lineages， YB and SX were one lineage， and YH belonged to another independent lineage. Population history and dynamics analysis showed that the gene flow of the three populations was insufficient， population divergence history indicated that YH might have diverged from SX first， and YB was produced by the contact fusion of SX and YH. ConclusionThe genetic diversity of snail populations in Jiaxing City is generally low， and the snail populations are unstable， with a great degree of genetic differentiation and insufficient gene flow among populations. This study can provide a basis for evaluating the effectiveness of the control of the snail as well as monitoring the trend of the spread of the snail.

Objective:To investigate effects of short-term cigarette smoke exposure combined with poly(I:C)stimulation on lung immune response and interferon expression in mice.Methods:BALB/c mice were randomly divided into 4 groups:control group,smoke group,poly(I:C)group and smoke combined poly(I:C)group.Total cell number and cell classification count of bronchoalveo-lar lavage fluid(BALF)were detected,and cell morphology was observed under ordinary light.Cytokines,chemokines,interferon and interferon stimulating genes expressions in lung tissues were detected by fluorescence quantitative PCR.Results:Compared with control group,total cell count,macrophage count and neutrophil count in smoke combined poly(I:C)group were significantly increased(P<0.05),and macrophage count was higher than that in poly(I:C)group.Macrophages of airway lavage fluid of mice in smoke combined with poly(I:C)group were larger in size,round or irregular in shape,and had more vacuoles in cytoplasm.Com-pared with control group,mRNA expressions of neutrophil chemokine CXCL1(P<0.05),CXCL2(P<0.01)and lymphocyte chemo-kine CCL2(P<0.01)in lung tissues of mice in smoke combined with poly(I:C)group were increased.IL-1β,IL-6,TNF-α mRNA expressions were significantly increased(P<0.01),IFN-β(P<0.01),IFN-γ(P<0.05),MX2(P<0.01)and IP-10(P<0.01)expre-ssions in lung tissues were significantly increased,and compared with poly(I:C)group,mRNA expressions of CXCL2(P<0.05),TNF-α(P<0.01)and IFN-β(P<0.05)in lung tissues of mice in smoke combined with poly(I:C)group were significantly increased.Conclusion:Cigarette smoke combined with poly(I:C)induces lung inflammation and expressions of interferon and interferon stimu-lating genes in mice.Cigarette exposure also increases poly(I:C)-induced acute lung inflammation and type Ⅰ interferon expression in mice.

Objective:To explore the impact of CACNA1C rs58619945 genotype on the cortical thickness of attentional networks in patients with Bipolar 1 disorder type (BD-Ⅰ). Methods:From August 2013 and August 2019, a total of 155 BD-Ⅰ patients were recruited from the outpatient and inpatient Departments of the Affiliated Brain Hospital of Guangzhou Medical University, along with 82 healthy controls (HC) from the community and university. Genotype for the CACNA1C rs58619945 locus was determined for all BD-I patients and HC subjects, followed by 3.0 T magnetic resonance imaging scans to measure the cortical thickness in the alert, orienting, and executive control subnetworks. General linear models (GLMs) were used to evaluate the impact of CACNA1C rs58619945 on the cortical thickness of attentional networks. Concurrently, attentional dimension functions were assessed using repeatable battery for the assessment of neuropsychological status (RBANS) and Cambridge neuropsychological test automated battery rapid visual information processing (CANTAB RVP) test. This study was approved by the Medical Ethics Committee of the Affiliated Brain Hospital of Guangzhou Medical University(Ethics No. 2023-056). Results:Compared with the HC group, the BD-Ⅰ patients had shown reduced thickness in bilateral prefrontal cortex, bilateral posterior cingulate cortex, and bilateral superior temporal cortex( P<0.05). A significant interaction between the CACNA1C genotype and the cortical thickness(HC vs.BD) of right prefrontal cortex, right posterior parietal cortex and right superior temporal cortex was noted( P<0.05). Partial correlation analysis has demonstrated a significant correlation between CANTAB RVP and RBANS attention indices and cortical thickness in the right prefrontal cortex, right posterior cingulate cortex( P<0.05), and right superior temporal cortex predominantly among carriers of the BD-Ⅰ G allele. Conclusion:The G allele of CACNA1C rs58619945 is associated with cortical thickness of the right prefrontal cortex, right posterior cingulate cortex, and right superior temporal cortex in BD-Ⅰ, which are part of the alerting and orienting network.

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 investigate the characteristics of hemodynamics of proper hepatic artery and portal vein after splenectomy and devascularization. Methods The clinical data of 103 patients with portal hypertension who underwent splenectomy and devascularization in the Capital Medical University-Affiliated You'an Hospital from April 2014 to February 2019 were retrospectively analyzed. Their hemodynamics of the proper hepatic artery and portal vein were recorded before and 1 week-, and 1-, 3-, 6-, 12-, and 24-months after surgery and then statistically analyzed. Continuous data with normal distribution were compared using paired-samples t test. Results Compared with the before surgery data, the portal vein diameter, portal vein flow, maximum velocity, and average velocity of the portal vein were all significantly decreased 1-week-, 1-, 3-, 6-, 12-, and 24-months after splenectomy and devascularization (all P < 0.05). The blood flow and velocity of the proper hepatic artery was significantly increased 1 week and 1 month after surgery (all P < 0.05); however, there was no statistically significant difference at 3-, 6-, 12-, and 24-months after surgery. Conclusion The diameter, flow, and flow velocity of the portal vein after splenectomy and devascularization were significantly lower than those before surgery, whereas the proper hepatic artery flow and flow velocity were increased within 1 month after surgery and then returned back to the pre-surgery levels 3 months after surgery.

Objective:To evaluate the effect of hyperthermia on the apoptosis and the expression levels of cysteine-containing aspartate-specific protease-3 (Caspase-3) and phosphorylated protein kinase B (p-AKT) in laryngeal squamous cell carcinoma cells.Methods:A prospective study was conducted on 30 patients with laryngeal squamous cell carcinoma who were treated at the First Affiliated Hospital of Zhengzhou University from October, 2021 to October, 2022. Three times of hyperthermia were performed with a time interval of 24 h. The tumor tissue samples were collected from 30 patients before and after hyperthermia and divided into before hyperthermia group (group A ) and after hyperthermia group (group B). Self-control study mode was adopted for comrparative analysis. The cell apoptosis was detected by TUNEL assay. The expression levels of Caspase-3 and p-AKT in the tissues were detected by immunohistochemistry. Positive cell ratio and immunohistochemistry (IHC) score were recorded. Comparison between two groups was performed by paired t-test. The correlation between the degree of apoptosis and the changes of Caspase-3 and p-AKT molecules was assessed by Pearson correlation analysis. Results:No evident adverse reactions were observed in 30 patients after hyperthermia. The apoptosis index of laryngeal squamous cell carcinoma cells in group A was 2.37%±1.33%, and 4.27%±3.93% in group B ( P=0.006). In group A, the ratio of Caspase-3 positive cells in tumor tissues was 62.31%±19.49% and 80.79%±17.15% in group B ( P=0.001). The ratio of p-AKT positive cells in group A was 31.26%±19.30%, and 26.26%±15.86% in group B ( P=0.023). There was a positive correlation between the degree of apoptosis and the changes of Caspase-3 molecule ( r=0.544, P=0.002), but a negative correlation was noted between the degree of apoptosis and the changes of p-AKT molecule ( r=-0.434, P=0.017). Conclusion:Hyperthermia can promote the apoptosis of tumor cells in laryngeal squamous cell carcinoma, which may be related to Caspase-3 dependent apoptosis, and the inhibition of AKT phosphorylation is also involved in this process.

Objective:To analyze the clinical epidemiological characteristics and the prognostic risk factors of patients with hemorrhagic fever with renal syndrome (HFRS).Methods:A total of 2 245 HFRS patients who were admitted to the Second Affiliated Hospital of Air Force Medical University from September 2008 to December 2021 were enrolled. Clinical epidemiological data (including gender, age, onset season, onset region, case fatality rate, et al) of HFRS patients were analyzed. The clinical epidemiological characteristics of patients with HFRS in the 2008 to 2012, 2013 to 2017, and 2018 to 2021 groups were compared. Statistical comparisons were performed using chi-square test. The Bonferroni adjusted P-value method was used for pairwise comparisons between groups, and logistic regression analysis was used to screen and evaluate the risk factors associated with the prognosis of HFRS patients. Results:The age of 2 245 HFRS patients was (42.3±15.9) years old. Most of them were male (79.24%(1 779/2 245)), and the main incidence area was Xi′an City (69.53%(1 561/2 245)). There were 132 deaths with an overall case fatality rate of 5.88%. There were 1 088 patients (48.46%) from 2008 to 2012, 647 patients (28.82%) from 2013 to 2017, and 510 patients (22.72%) from 2018 to 2021, with a mortality rate of 7.17%(78/1 088), 5.10%(33/647) and 4.12%(21/510), respectively. From 2008 to 2021, both the number of HFRS cases and the case fatality rate had shown a fluctuating downward trend. There were significant differences in case fatality rate, age distribution, onset season, and onset region among patients in the different year groups ( χ2=6.84, 49.22, 83.47 and 19.29, respectively, all P<0.05). The results of pairwise comparisons showed that the proportion of patients aged >60 years in the 2018 to 2021 group (23.33%(119/510)) was higher than those in the 2008 to 2012 group (12.13%(132/1 088)) and the 2013 to 2017 group (12.36%(80/647)), and the differences were statistically significant (both P<0.05). The proportions of patients at large peak (October to December) were 62.35%(318/510) in the 2018 to 2021 group and 56.26%(364/647) in the 2013 to 2017 group, which were both lower than that in the 2008 to 2012 group (75.18%(818/1 088)), and the differences were both statistically significant (both P<0.05). The case fatality rate of patients aged >60 years was 9.67%(32/331), which was higher than those of patients aged <30 years (2.86%(16/559)) and patients aged 30 to 60 years (6.20%(84/1 355)), with statistically significant differences (both P<0.05). Univariate analysis showed that age 30 to 60 years, age >60 years, smoking, complicated with hypertension, hypotensive shock and hypoxemia were significantly correlated with the prognosis of HFRS patients (odds ratio ( OR)=2.243, 3.632, 1.484, 3.532, 79.422 and 143.955, respectively, all P<0.05). The results of multivariate logistic regression analysis indicated that complicated with hypertension ( OR=2.467, P=0.004), hypotensive shock ( OR=11.658, P=0.001), and hypoxemia ( OR=67.767, P<0.001) were the independent risk factors affecting the prognosis of HFRS patients. Conclusions:The prevalence of HFRS has shown new changing characteristics from 2008 to 2021. The numbers of HFRS patients and the case fatality rates show a downward trend, and the proportion of HFRS patients aged >60 years increases. Complicated with hypertension, hypotensive shock and development with hypoxemia are the independent risk factors for the prognosis of HFRS.

ObjectiveTo investigate the incidence and influencing factors of postpartum depression and anxiety in Urumqi during the coronavirus disease （COVID-19） epidemic period in 2020. MethodsResearch subjects were the parturients who underwent postpartum health checkups in a third class hospital in Urumqi from January 2020 to December 2020. The maternal socio demographic and obstetric information were collected， and PHQ-9 and GAD-7 scales were used for screening of PPD and PPA. Calcaneal bone mineral density of the parturients was measured by French Pegasus ultrasonic bone densitometer. After univariate analysis of the related influencing factors of PPD and PPA， multivariate binary logistic regression analysis was used to explore the relationship between mental disorders and various influencing factors. ResultsA total of 2 490 puerpera participated in the survey. The incidences of PPD and PPA in 2020 were 13.4 % and 10.8 %， respectively. Six factors with statistical differences after univariate analysis were included in multivariate binary logistic regression analysis. The final results suggested that age over 35 （OR=1.707，95%CI：1.142‒2.551）， unemployment （OR=1.478，95%CI：1.003‒2.205）， multipara（OR=1.340，95%CI：1.037‒1.733）， bone loss and osteoporosis （OR=1.434，95%CI： 1.076‒1.910） were the risk factors of PPD， while breastfeeding （OR=0.466，95%CI： 0.301‒0.721） was a protective factor. Ages between 18‒24 （OR=1.559，95%CI：1.282‒3.097） and cesarean section （OR=1.433，95%CI： 1.105‒1.859） were the risk factors of PPA， while ages between 30‒34 years old （OR=0.524，95%CI： 0.332‒0.827）， occupation as medical staff （OR=0.282，95%CI： 0.807‒0.919）， breastfeeding （OR=0.530，95%CI： 0.330‒0.850） were protective factors. ConclusionIncidences of PPD and PPA are in middle-low levels during COVID-19 epidemic period. Age， occupation， delivery mode， delivery times， feeding pattern and bone mineral density are the influencing factors. Screen coverage of PPD and PPA in special period should be strengthened， and measures should be taken to reduce the risk.

Objective:To investigate the clinical manifestations, diagnosis, treatment and prognosis of Kawasaki disease (KD) complicated with acute abdomen in children.Methods:Clinical manifestations, laboratory examinations, abdominal B-ultrasound scans, abdominal plain films, abdominal CT findings, coronary artery lesions and prognosis of 16 children with KD and acute abdomen admitted to Guangzhou Women and Children′s Medical Center, Guangzhou Medical University from August 1, 2015 to July 31, 2019 were retrospectively analyzed.The measurement data of age, leukocyte, hemoglobin, platelet and biochemical indexes are expressed by M (range). Results:A total of 16 cases were included, involving 7 males and 9 females aged 4 years and 8 months (7 months to 8 years). Among them, 9 cases of KD complicated with cholecystitis, 5 cases with intestinal obstruction, 2 cases with acute appendicitis, 2 cases with necrotizing enterocolitis, 2 cases with acute peritonitis and 1 case with acute pancreatitis.There were 3 cases complica-ted with 2 or more kinds of acute abdomen diseases.All 16 patients had symptoms of abdominal pain, 7 cases had vomiting, 4 cases had obvious abdominal distension and 1 case had bloody stool.Abdominal B-ultrasound was performed in all cases, and 8 cases showed enlargement of gallbladder and edema and thickening of gallbladder wall, 2 cases of appendicitis, 2 cases of intestinal obstruction and 1 case of pancreatic enlargement.Abdominal plain film examination was performed in 8 cases, suggesting necrotizing enterocolitis in 2 cases and intestinal obstruction in 2 cases.Abdominal CT examination was performed in 3 cases, including edema of gallbladder wall in 1 case, peritonitis in 1 case, intestinal obstruction in 2 cases and enlargement of pancreas in 1 case.All the 16 cases were treated with pulsed intravenous immunoglobulin (IVIG) at 2 g/kg and antiplatelet agents.Eight IVIG-resistant cases were treated with the second dose of IVIG at 2 g/kg, among whom, 4 children still had fever and intravenous Methylprednisone was given.Two cases underwent enterostomy and abdominal puncture drainage.All the 16 children were followed up until 6 months after discharge, and 4 cases (25%) were complicated with coronary artery aneurysm (CAA) during the acute stage or follow-up period.Conclusions:KD complicated with acute abdomen is more commonly manifested as cholecystitis and intestinal obstruction.Besides the classic symptoms of KD, abdominal pain and vomiting are the most common in KD with acute abdomen.Abdominal ultrasound, plain film and CT examinations are conductive to the early diagnosis of KD complicated with acute abdomen.In addition, the incidence of IVIG-resistance and CAA is relatively high in children with KD complicated with acute abdomen.
