Objective: To evaluate the intervention efficacy of integrated group social skills training on social ability in school age patients with high functioning ASD, so as to provide a reference for improving social skills in children with high functioning ASD. Methods: From January 2021 to December 2023, 62 children aged 7-12 with high functioning ASD who visited the Children s Psychiatry Outpatient Department of the Affiliated Kangning Hospital of Ningbo University were recruited, and were randomly divided into a training ( n =31) and a control group ( n =31) by a random number table method. The training group received a 20 week structured group social training program (mental interpretation courses and social courses), while the control group received only conventional treatment. Chinese version of Griffith Empathy Measure Parent Ratings (GEM-PR) and Social Response Scale (SRS) were used to assess the symptoms of social deficits before and after treatment. Emotional face recognition tasks and eye movement trajectories were used to test the characteristics of social visual attention in children with ASD. Group comparison was conducted using t-test and Mann-Whitney U test. Results: At baseline, there were no significant differences in GEM-PR score ( t = -1.20 to -0.81), SRS score ( t =-0.36-1.75), emotional face recognition accuracy and reaction time ( t =-0.58-1.85), and eye movement trajectory ( U/t =-1.63-0.29) between the two group ( P >0.05). After intervention, the total GEM-PR score and empathic cognitive factor score of training group [18.00(10.00，24.00)，9.00(8.00，13.00)] were significantly higher than those of the control group [12.00(-1.00，18.00)，2.00(-2.00，7.00)], and the total SRS score and social cognition, social perception, social communication, social motivation (73.23±14.20, 16.16±2.72, 6.58±2.50, 24.29±5.61, 9.52±3.73) were significantly lower than those of the control group (95.26±15.29, 19.90±2.84, 12.58±2.49,31.94±6.38, 13.74±4.81) ( U/t =-2.38, -4.59; -5.88, -5.29, -9.47, -5.01, -3.87, P <0.05). The overall correct rate of emotional face recognition and the correct rate of angry, fearful and neutral faces recognition in the training group [(81.55±6.62)%，(76.86±12.06)%，(79.61±12.42)%，(94.27±6.26)%] were significantly higher than the control group [(70.55±13.82)%，(62.82±18.77)%，(67.18±18.85)%，(79.60±20.05)%], and the average reaction time [(2 226.70±274.43)ms] was lower than the control group [(2 417.27±324.10)ms] (t=4.00, 3.50, 3.07, 3.89, -2.42, P<0.05). The time to first eye gaze [764.74 (748.64, 793.73) ms] in the training group was significantly lower than that in the control group [810.92 (782.86, 877.42) ms], and the proportion of moderatetohigh intensity attention area in the face [(37.37±1.27)%] was significantly higher than that in the control group [(30.34±1.23)%] (U/t=3.44, 8.89, P<0.05). Conclusion Integrated group social training can significantly improve the social communication and empathy ability of high functioning ASD children, increase active attention and recognition ability of faces, and improve mental development of children with ASD.

BACKGROUND: The effect of the interval between previous Helicobacter pylori (H. pylori) eradication and rescue treatment on therapeutic outcomes remains unknown. The aim of this study was to investigate the association between eradication rates and treatment interval durations in H. pylori infections. METHODS: This prospective observational study was conducted from December 2021 to February 2023 at six tertiary hospitals in Shandong, China. We recruited patients who were positive for H. pylori infection and required rescue treatment. Demographic information, previous times of eradication therapy, last eradication therapy date, and history of antibiotic use data were collected. The patients were divided into four groups based on the rescue treatment interval length: Group A, ≥4 weeks and ≤3 months; Group B, >3 and ≤6 months; Group C, >6 and ≤12 months; and Group D, >12 months. The primary outcome was the eradication rate of H. pylori . Drug compliance and adverse events (AEs) were also assessed. Pearson's χ2 test or Fisher's exact test was used to compare eradication rates between groups. RESULTS: A total of 670 patients were enrolled in this study. The intention-to-treat (ITT) eradication rates were 88.3% (158/179) in Group A, 89.6% (120/134) in Group B, 89.1% (123/138) in Group C, and 87.7% (192/219) in Group D. The per-protocol (PP) eradication rates were 92.9% (156/168) in Group A, 94.5% (120/127) in Group B, 94.5% (121/128) in Group C, and 93.6% (190/203) in Group D. There was no statistically significant difference in the eradication rates between groups in either the ITT ( P = 0.949) or PP analysis ( P = 0.921). No significant differences were observed in the incidence of AEs ( P = 0.934) or drug compliance ( P = 0.849) between groups. CONCLUSION: The interval duration of rescue treatment had no significant effect on H. pylori eradication rates or the incidence of AEs. REGISTRATION ClinicalTrials.gov , NCT05173493.

Objective To investigate the effect of Xuefu Zhuyu Decoction combined with external counterpulsation therapy on angina pectoris attacks and brachial artery flow-mediated dilation(FMD)in patients with angina pectoris of heart blood stasis syndrome.Methods A total of 80 patients with stable coronary artery disease(SCAD)and angina pectoris who visited our hospital between March 2022 and December 2023 were selected as study subjects and randomly divided into control group(40 cases)and treatment group(40 cases).The control group received conventional treatment and Xuefu Zhuyu Decoction,while the treatment group received external counterpulsation therapy in addition to the control group's treatment.The angina pectoris attacks before and after treatment in both groups was recorded.Color Doppler ultrasound was used to measure brachial artery FMD;electrocardiogram was used to measure heart rate variability indicators,including the standard deviation of the average of normal to normal intervals(SDANN)for 5 consecutive minutes,standard deviation of normal to normal intervals(SDNN),and square root of the mean of the sum of the squares of the differences between consecutive N-N intervals(rMSSD).A fully automatic biochemical analyzer was used to measure blood lipid indicators such as high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),total cholesterol(TC),and triglycerides(TG).Nitrate reductase method was used to detect serum nitric oxide(NO)levels,and enzyme-linked immunosorbent assay(ELISA)was used to detect serum endothelin-1(ET-1)levels.Adverse events in both groups were recorded.Results After treatment,the attack frequency of angina pectoris decreased and duration shortened in both groups compared with before treatment,and the attack frequency of angina pectoris was lower and duration shorter in the treatment group than in the control group(P＜0.05).After treatment,FMD and NO levels increased,and ET-1 levels decreased in both groups compared with before treatment,and FMD and NO levels were higher,while ET-1 levels were lower in the treat-ment group than in the control group(P＜0.05).After treatment,SDANN,SDNN,and rMSSD in-creased in both groups compared with before treatment,and SDANN,SDNN,and rMSSD were higher in the treatment group than in the control group(P＜0.05).After treatment,HDL-C levels in-creased,while LDL-C,TC,and TG levels decreased in both groups compared with before treatment,and HDL-C levels were higher,while LDL-C,TC,and TG levels were lower in the treatment group than those in the control group(P＜0.05).No serious adverse reactions occurred during treatment in both groups,and vital signs were normal,with normal liver and kidney function.Conclusion Xuefu Zhuyu Decoction combined with external counterpulsation can effectively alleviate clinical symptoms,reduce the frequency of angina pectoris attacks,shorten the duration of angina pectoris,improve brachial artery FMD,endothelial function,heart rate variability,and blood lipid levels in patients with angina pectoris of heart blood stasis syndrome.Besides,it has higher safety.

ObjectiveTo investigate the association of the polymorphisms of the acetyl-CoA acetyltransferase 1 （ACAT1） gene and the melatonin receptor 1B （MTNR1B） gene with the susceptibility to nonalcoholic fatty liver disease （NAFLD）. MethodsA total of 164 healthy controls and 228 NAFLD patients were enrolled in this study. PCR and sequencing methods were used to determine the genotypes of the polymorphisms of the ACAT1 gene at the rs1044925 and rs1157651 loci and the MTNR1B gene at the rs10830963 locus， and fasting venous blood samples were collected for biochemical analysis. The t-test was used for comparison of normally distributed continuous data between groups， and the non-parametric Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups； the chi-square test was used for comparison of categorical data between groups. ResultsThere were no significant differences between the NAFLD group and the healthy control group in the genotype distribution of the ACAT1 gene at the rs1044925 and rs1157651 loci and the MTNR1B gene at the rs10830963 locus （all P>0.05）. The carriers of AA genotype at the rs1044925 locus of the ACAT1 gene had a significantly higher level of low-density lipoprotein than the carriers of C allele （Z=-2.08， P=0.04）， and the carriers of G allele at the rs10830963 locus of the MTNR1B gene had a significantly higher level of fasting blood glucose than the carriers of CC genotype （Z=-3.01， P<0.01）. ConclusionThe polymorphisms of the ACAT1 gene at the rs1044925 and rs1157651 loci and the MTNR1B gene at the rs10830963 locus were not associated with the susceptibility to NAFLD. The rs1044925 locus of the ACAT1 gene and the rs10830963 locus of the MTNR1B gene are associated with the levels of low-density lipoprotein and fasting blood glucose， respectively.

Objective: To explore the effects of group sports game intervention on social ability and quality of life of children with austism spectrum disorders (ASD),so as to provide reference for rehabilitation intervention of social and quality of life of children with ASD. Methods: From September 2021 to January 2022, 72 children with ASD aged 4-6 in the children s rehabilitation department of Xiangyang Central Hospital were selected to participate in the study, and were randomly divided into experimental group ( n =36) and control group ( n =36). The control group received routine rehabilitation training (including individual sports game training), and the experimental group replaced individual sports game training with group sports game training on the basis of routine rehabilitation.The course content mainly included three parts: warm up before class, group sports games and relaxation after class. The course combined social skills with sports games, and was carried out in a group form (divided into 12 groups with 3 people in each group), and was trained five times a week for 60 minutes, for a total of 12 weeks. The scores of Childhood Autism Rating Scale (CARS), Autism Treatment Evaluation Checklist (ATEC), Social Responsiveness Scale (SRS) and Pediatric Quality of Life Inventory Version 4.0 Generic Core Scales (PedsQL 4.0) were observed before and after treatment. t-test and χ 2 test were used for statistical analysis. Results: There was no significant difference in SRS scores between the experimental group and the control group before intervention ( t =-0.63, P >0.05). After the intervention, the total response rate in the experimental group was 83.33 %, higher than 41.67% in the control group χ 2=13.33, P <0.05),and the SRS scores decreased in the experimental group and control group ( t =17.75,8.71, P <0.05). The SRS scale score of the experimental group Social perception (17.67±4.12) , social cognition (30.33±4.99) , social communication (50.33±9.39) , social motivation (24.25±6.78) scores and total scores ( 152.67± 25.82) were lower than those of the control group(22.17±5.34，36.00±4.13，62.58±11.07，34.42±7.13，186.33±29.03)( t = -4.88，-2.03，-2.13，-3.58，-3.01， P ＜0.05).After the intervention, the scores of social function (53.33±18.01) and total score (283.83±51.83) on PedsQL 4.0 scale in experimental group were higher than those in control group(23.33±15.13，218.00±39.01) ( t =4.42，3.52， P ＜0.05). After the intervention, Autism Treatment Evaluation Scale (ATEC) scores of experimental groups(44.33±14.72) was lower than that in control group ( 59.33±16.95)( t =-2.32, P ＜0.05).

OBJECTIVE To design and synthesize novel α-naphthylthiol amino acid ester lysine specific demethylase 1(LSD1) inhibitors, evaluate their inhibitory activity with selectivity against LSD1, and explore their binding mechanism through molecular docking and dynamics simulation. METHODS Based on the binding mode of hit compound 3a with LSD1, the α- naphthyl mercapto amino acid ethyl ester small molecule compound were designed by fixing the planar hydrophobic naphthyl ring in the structure, while introducing hydrophilic amino fragment, and they were prepared through a multi-component one-pot cascade reaction. All the compounds were evaluated for their inhibitory activity against LSD1 at concentrations of 5.0 and 1.0 μmol·L–1 using the LSD1 screening platform of research group. The most potent compound was tested for its IC50 value and enzyme selectivity over MAO-A and MAO-B, and its binding mode was investigated through molecular docking and dynamics simulation. RESULTS A total of 13 compounds were obtained, all of which exhibited significant inhibitory effects on LSD1. Among them, nine compounds showed an inhibitory rate of over 50.0% against LSD1 at a concentration of 1.0 μmol·L–1, while compound 3l displaying the best activity with an IC50 value of 0.17 μmol·L–1, 174 times higher than the positive control. It also showed excellent selectivity towards MAO-A and MAO-B. Molecular docking and dynamics simulations indicated that compound 3l inhibited the activity of LSD1 through multiple interactions. CONCLUSION The structures of α-naphthylthiol amino acid ester can serve as lead compounds or active fragments, laying a solid foundation for the subsequent design of LSD1 inhibitors based on structure-oriented drug design.

Objective To investigate the relationship between circular RNA homeodomain interacting protein ki-nase 3 (circHIPK3) and the activation of rat microglia (RM) cells.Methods In vitro, RM cells were cultured and randomized into normal and oxygen-glucose deprivation/reperfusion (OGD/R) groups, and the expression lev-el of circHIPK3 in each group was detected by RT-qPCR.The circHIPK3 lentiviral vector with puromycin resist-ance was constructed, and the overexpression (OE) group and negative control (NC) group were set up.The opti-mal multiplicity of infection (MOI) for RM cells was determined based on fluorescence expression, and puromycin was used to screen RM cells stably expressing circHIPK3 .The cells of OE and NC groups were treated with OGD/R, and the expression levels of ionized calcium binding adaptor molecule 1 (Iba-1) and eukaryotic tumor necrosis factor receptor superfamily (CD40) were detected by Western blot.The circHIPK3 translational protein potential was analyzed by the circRNAdb database, while the potential binding microRNAs on circHIPK3 were predicted by circBank and Starbase databases.Results OGD/R down-regulated circHIPK3 in RM cells (P <0.0001).The sequencing results were accurate and the lentiviral vector of circHIPK3 was constructed successfully.The optimal MOI of RM cells was 80 , puromycin at a concentration of 2μg/ml was used to screen RM cell lines stably express-ing circHIPK3 .RT-qPCR results showed that the expression level of circHIPK3 was significantly higher in the OE group compared with the NC group (P<0.01) .Western blot results revealed that the expression levels of Iba-1 and CD40 in the OE group were markedly lower than those in the NC group (P<0.05) .Protein translation analy-sis showed that circHIPK3 encoded a polypeptide of 404 amino acids with two internal ribosome entry sites (IRES) and an open reading frame (ORF) .Database analysis uncovered that circHIPK3 could target eight specific miR-Nas, namely hsa-miR-3529-5p, hsa-miR-379-5p, hsa-miR-506-3p, hsa-miR-33, hsa-miR-450b-5p, hsa-miR-551b-3p, hsa-miR-193, and hsa-miR-508-3p.Conclusion The overexpression of circHIPK3 effectively suppres-ses OGD/R-induced activation of RM cells.It has the potential to encode peptides and may act as a miRNA sponge.These findings provide a foundation for further study of circHIPK3 functions.

Objective:To evaluate the immunogenicity, safety, and immune persistence of the sequential booster with the recombinant protein-based COVID-19 vaccine (CHO cell) in healthy people aged 18-84 years.Methods:An open-label, multi-center trial was conducted in October 2021. The eligible healthy individuals, aged 18-84 years who had completed primary immunization with the inactivated COVID-19 vaccine 3 to 9 months before, were recruited from Shangyu district of Shaoxing and Kaihua county of Quzhou, Zhejiang province. All participants were divided into three groups based on the differences in prime-boost intervals: Group A (3-4 months), Group B (5-6 months) and Group C (7-9 months), with 320 persons per group. All participants received the recombinant COVID-19 vaccine (CHO cell). Blood samples were collected before the vaccination and after receiving the booster at 14 days, 30 days, and 180 days for analysis of GMTs, antibody positivity rates, and seroconversion rates. All adverse events were collected within one month and serious adverse events were collected within six months. The incidences of adverse reactions were analyzed after the booster.Results:The age of 960 participants was (52.3±11.5) years old, and 47.4% were males (455). The GMTs of Groups B and C were 65.26 (54.51-78.12) and 60.97 (50.61-73.45) at 14 days after the booster, both higher than Group A′s 44.79 (36.94-54.30) ( P value<0.05). The GMTs of Groups B and C were 23.95 (20.18-28.42) and 27.98 (23.45-33.39) at 30 days after the booster, both higher than Group A′s 15.71 (13.24-18.63) ( P value <0.05). At 14 days after the booster, the antibody positivity rates in Groups A, B, and C were 91.69% (276/301), 94.38% (302/320), and 93.95% (295/314), respectively. The seroconversion rates in the three groups were 90.37% (272/301), 93.75% (300/320), and 93.31% (293/314), respectively. There was no significant difference among these rates in the three groups (all P values >0.05). At 30 days after the booster, antibody positivity rates in Groups A, B, and C were 79.60% (238/299), 87.74% (279/318), and 90.48% (285/315), respectively. The seroconversion rates in the three groups were 76.92% (230/299), 85.85% (273/318), and 88.25% (278/315), respectively. There was a significant difference among these rates in the three groups (all P values <0.001). During the sequential booster immunization, the incidence of adverse events in 960 participants was 15.31% (147/960), with rates of about 14.38% (46/320), 17.50% (56/320), and 14.06% (45/320) in Groups A, B, and C, respectively. The incidence of adverse reactions was 8.02% (77/960), with rates of about 7.50% (24/320), 6.88% (22/320), and 9.69% (31/320) in Groups A, B, and C, respectively. No serious adverse events related to the booster were reported. Conclusion:Healthy individuals aged 18-84 years, who had completed primary immunization with the inactivated COVID-19 vaccine 3 to 9 months before, have good immunogenicity and safety profiles following the sequential booster with the recombinant COVID-19 vaccine (CHO cell).
