Autism Spectrum Disorder (ASD) is marked by early-onset neurodevelopmental anomalies, yet the temporal dynamics of genetic contributions to these processes remain insufficiently understood. This study aimed to elucidate the role of the Shank3 gene, known to be associated with monogenic causes of autism, in early developmental processes to inform the timing and mechanisms for potential interventions for ASD. Utilizing the Shank3B knockout (KO) mouse model, we examined Shank3 expression and its impact on neuronal maturation through Golgi staining for dendritic morphology and electrophysiological recordings to measure synaptic function in the anterior cingulate cortex (ACC) across different postnatal stages. Our longitudinal analysis revealed that, while Shank3B KO mice displayed normal neuronal morphology at one week postnatal, significant impairments in dendritic growth and synaptic activity emerged by two to three weeks. These findings highlight the critical developmental window during which Shank3 is essential for neuronal and synaptic maturation in the ACC.

Objective:To explore the influences of FibroScan detection on the pregnancy outcomes of pregnant rats transfected with hepatitis B virus and the growth of their offspring rats.Methods:Sixty SPF-grade SD rats with a male-to-female ratio of 5∶1 were selected，randomly divided the female rats into the groups of mid-pregnancy with hepatitis B，late-pregnancy with hepatitis B，normal mid-pregnancy，normal late-pregnancy，and control group，and the rats in the mid-pregnancy and late-pregnancy groups were subjected to FibroScan testing on the 10th and 15th days of gestation respectively. The number of offspring rats in each group was randomly reduced to 10 on the 3rd day after delivery，and the offspring rats were divided into the groups of mid-pregnancy with hepatitis B，late-pregnancy with hepatitis B，normal mid-pregnancy，normal late-pregnancy，and control group. The pregnancy outcome levels of pregnant rats were observed by adopting a stratified analysis strategy，including differences in weight changes，number of deliveries，fetal rat outcomes，lactation conditions，litter size，and litter weight. The growth levels of offspring rats，including differences in weight，body length，tail length，and the time of fur growth，tooth eruption，eye opening，and ear standing on the 21st day were observed，and the survival rate of the offspring rats was compared.Results:With regard to the pregnancy outcome levels of the pregnant rats，there were no statistically significant differences in weight changes during pregnancy among the five groups of pregnant rats［ F（4，45）=2.627，Adjusted P=0.222］. There were also no statistically significant differences in the number of deliveries，fetal rat outcomes，and lactation conditions（Adjusted P=1.000）. The number of deliveries［ F（4，21.095）=2.280，Adjusted P=0.222］and litter weight［ F（4，20.128）=2.159，Adjusted P=0.222］showed no statistically significant differences. After correction using the BH method，none of the indicators showed significant differences（ P>0.05）. In terms of the growth levels of the offspring rats，among the five groups of offspring rats，there were no statistically significant differences in body weight on the 21st day［H（4）=11.623，Adjusted P=0.135］，body length on the 21st day［H（4）=10.962，Adjusted P=0.135］，and tail length on the 21st day［H（4）=9.126，Adjusted P=0.058］. Besides，the differences in the time of fur growth，tooth eruption，eye opening，and ear standing［H（4）=0.000，Adjust P=1.000］showed no statistical significance. The survival rate on the 7th day，14th day，and 21st day was 100%，with no significant differences（Adjusted P=1.000）. After correction using the BH method，none of the indicators showed significant differences（ P>0.05）. Conclusion:FibroScan detection had no significant influences on the pregnancy outcomes of pregnant rats with hepatitis B or on the growth of their offspring rats in multiple stages，dimensions，and indicators，indicating that FibroScan detection is safe for pregnant rats. This research provides an animal experimental basis for the safe use of FibroScan in pregnant women with chronic HBV infection.

Objective To analyze the expression of serum mannose binding lectin associated serine protease 1(MASP1)and protein kinase D2(PRKD2)in locally advanced cervical cancer(LACC)patients,and their relationship with the efficacy of neoadjuvant chemotherapy(NACT).Methods The clinical data of 98 LACC patients(LACC group)treated with NACT in the hospital from March 2019 to April 2021 were retrospective-ly selected,and they were divided into effective group(n=76)and ineffective group(n=22)according to the efficacy.Fifty patients with early cervical cancer diagnosed and treated in the same period were selected as the early cervical cancer group,and 50 female health examination subjects were selected as the healthy control group.Enzyme-linked immunosorbent assay was applied to detect serum levels of MASP1 and PRKD2.Logis-tic regression analysis was applied to analyze the influencing factors of NACT efficacy.The evaluation value of serum MASP1 and PRKD2 on the efficacy of NACT were analyzed by the receiver operating characteristic curve.Results The serum levels of MASP1 and PRKD2 in the LACC group were higher than those in the ear-ly cervical cancer group and the control group,and the differences were statistically significant(P＜0.05).The serum levels of MASP1 and PRKD2 in LACC group were correlated with International Federation of Gy-necology and Obstetrics(FIGO)stage and pathological grade,and the serum levels of MASP1 and PRKD2 in patients with FIGO stage Ⅲ and pathological grade G3 were higher(P＜0.05).FIGO stage Ⅲ proportion,se-rum MASP1 and serum PRKD2 levels in NACT ineffective group were higher than those in effective group(P＜0.05).FIGO stage Ⅲ,serum MASP1 and serum PRKD2 were independent risk factors for NACT efficacy in LACC patients(P＜0.05).The area under the curve of serum MASP1 and PRKD2 combined to evaluate the efficacy of NACT was 0.883(95％CI:0.828-0.935),which was larger than 0.802(95％CI:0.761-0.846)and 0.825(95％CI:0.764-0.852)predicted by the single index,and the difference were statistically significant(Z=4.111,5.012,both P＜0.001).Conclusion Level of serum MASP1 and PRKD2 in LACC pa-tients are increase,which are independent risk factors affecting the efficacy of NACT.Combined detection of MASP1 and PRKD2 has high predictive value for NACT efficacy.

Objective To explore the efficacy of carotid color Doppler ultrasonography(CDU)combined with transcranial color Doppler ultra sonography(TCCD)in the diagnosis of carotid artery stenosis in elderly patients with acute cerebral infarction(ACI).Methods The clinical data of 306 elderly patients with suspected ACI who were admitted to the Second Affiliated Hospital of Air Force Medical University,and received CDU and TCCD from May 2021 to May 2023 were retrospectively analyzed.The result of digital subtraction angiography(DSA)was taken as the gold standard.The patients were assigned to cerebral infarction group or non-cerebral infarction group according to the gold standard.CDU parameters(peak systolic velocity[PSV]and end diastolic velocity[EDV]of the common carotid artery])and TCCD parameters(resistance index[RI]and pulsatility index[PI]of posterior cerebral artery[PCA])were compared between the two groups.According to the degree of carotid artery stenosis,ACI patients were assigned to mild stenosis subgroup,moderate stenosis subgroup or severe stenosis subgroup.CDU parameters(PSV,EDV)and TCCD parameters(RI,PI)were compared among subgroups.The efficacy of related parameters in the diagnosis of ACI and the degree of carotid artery stenosis was evaluated by receiver operating characteristic(ROC)curve.Results There were 155 patients(50.65%)in the cerebral infarction group and 151 patients(49.35%)in the non-cerebral infarction group.The cerebral infarction group had higher EDV,PSV and RI and lower PI than the non-cerebral infarction group(P＜0.05).The areas under curve(AUC)values of ROC curves of EDV,PSV,RI,PI and their combination in the diagnosis of ACI were 0.577,0.563,0.644,0.643 and 0.726(P＜0.05).The levels of EDV,PSV and RI in the subgroups were as follows:severe stenosis subgroup＞moderate stenosis subgroup＞mild stenosis subgroup,and the change trend of PI was shown as mild stenosis subgroup＞moderate stenosis subgroup＞severe stenosis subgroup(P＜0.05).The AUC values of ROC curves of EDV,PSV,RI,PI and their combination in evaluating the degree of carotid artery stenosis in ACI patients were 0.767,0.802,0.845,0.846 and 0.952(P＜0.05).Conclusion Carotid CDU combined with TCCD can effectively diagnose ACI and carotid artery stenosis,and has high application value for the evaluation of carotid artery stenosis in elderly ACI patients.

Objective To investigate the association between gout-related gene polymorphisms and clinical phenotypic heterogeneity among gout patients in the Foshan region,thereby providing a scientific basis for stratified clinical management.Methods A total of 125 gout patients diagnosed at the Foshan Hospital of Traditional Chinese Medicine between June 2022 and May 2025 were enrolled in this study.The collected data included demo-graphic characteristics,frequency of gout attacks,presence of tophi,levels of uric acid,creatinine,C-reactive protein(CRP),erythrocyte sedimentation rate(ESR),gout-related genes(ABCG2,SLC2A9,SLC22A12,MTHFR),and joint ultrasound findings.Group comparisons and rank correlation analyses were conducted to explore potential associations between gene polymorphisms and clinical heterogeneity.Results The male-to-female ratio was 11∶1;the mean age was(35.28±2.67)years;the mean disease duration was(6.03±0.68)years;and the mean frequency of acute attacks in the past 12 months was 4(2.0,7.25).Genotype distributions were as follows:ABCG2:wild-type(C/C),23.8%;heterozygous(C/A),53.2%;homozygous(A/A),23%.SLC2A9:wild-type(A/A),24.6%;heterozygous(A/G),50%;homozygous(G/G),25.4%.SLC22A12:wild-type(A/A),4.8%;heterozygous(A/C),31.7%;homozygous(C/C),63.5%.MTHFR:wild-type(C/C),68.3%;heterozygous(C/T),28.6%;homozygous(T/T),3.2%.Rank correlation analysis revealed that SLC2A9 polymorphisms were significantly correlated with tophi formation(ρ=0.193,P=0.031)and crystal deposition on ultrasound(ρ=0.202,P=0.025).SLC22A12 polymorphisms were associated with hypertension(ρ=0.269,P=0.003)and diabetes(ρ=0.200,P=0.026).MTHFR polymorphisms showed a correlation with diabetes(ρ=0.224,P=0.012).Conclusions Polymorphisms in SLC2A9,SLC22A12,and MTHFR are significantly linked to clinical phenotypic heterogeneity among gout patients.Genetic testing could facilitate the early identification of individuals at high risk for complications and support the development of stratified and individualized treatment approaches.

Objective:To integrate the symptom management experiences of patients with acute decompensated heart failure (ADHF), so as to provide a basis for developing symptom management measures.Methods:Qualitative or mixed studies on the symptom management experience of ADHF patients included from establishment of the database to September 2024, were electronically retrieved in PubMed, CINAHL, Cochrane Library, Web of Science, Embase, EBSCO, China National Knowledge Infrastructure, WanFang Data, VIP, China Biomedical Database and other Chinese and English databases and gray literature databases. The quality of the literature was evaluated using the Critical Appraisal Skills Programme developed by the Center for Evidence-Based Medicine at the University of Oxford. The results were synthesized through the aggregative integration method.Results:A total of 14 papers were included. Thirty-four findings were distilled into eight categories and three integrative findings, namely, the multiple challenges posed by symptoms (complex and multiple symptomatic somatic experiences, symptom-induced mood changes, and reduced family and social engagement), the unmet needs of patients (insufficient healthcare resources, insufficient supply of discharge services provided by healthcare organizations, and lack of knowledge), and the co-existence of positive and negative coping styles (negative coping styles in symptomatic distress, positive debugging and diversified coping in symptomatic distress) .Conclusions:ADHF symptoms severely affect patients' physical, psychological, and social function. Healthcare professionals should focus on the unmet needs of patients with ADHF and explore patient-engaged models of active symptom management.

Objective To investigate the effect of thalidomide combined with infliximab (IFX) in treatment of refractory inflammatory bowel disease (IBD) and its effects on insulin-like growth factor-1 (IGF-1) and transforming growth factor-β1 (TGF-β1). Methods A total of 120 patients with refractory IBD were randomly divided into experimental group and control group, with 60 cases in each group. The two groups were given conventional treatment (mesalazine), the control group was given IFX, and the experimental group was given IFX combined with thalidomide, continuous treatment for two months. The efficacy, intestinal flora disturbance rate, adverse reactions, Crohn's disease activity index (CDAI), Lewis score, serum IGF-1, TGF-β1 levels and nutritional status indexes[albumin (ALB), transferrin (Tf)]before and after treatment for 1 month and 2 months of the two groups were compared. Results The total effective rate of the experimental group was significantly higher than that of the control group (P < 0.05). After one month and two months of treatment, CDAI and Lewis scores of the experimental group were significantly lower than those of the control group (P < 0.05); the serum levels of IGF-1, TGF-β1 as well as ALB and Tf in the experimental group were significantly higher than those in the control group (P < 0.05). The improvement of intestinal flora disturbance rate in the experimental group was significantly better than that in the control group (P < 0.05). There was no significant difference in the incidence of oral and nasal mucosa dryness, throat discomfort, nausea and vomiting between two groups (P>0.05). Conclusion In the treatment of refractory IBD patients, thalidomide combined with IFX can regulate serum IGF-1 and TGF-β1 levels, effectively relieve clinical manifestations, inhibit inflammatory activities, and improve nutritional status and intestinal flora disorders of patients, and it has high safety.
