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.

ObjectiveTo investigate the effects of Scutellariae Radix combined with epidermal growth factor receptor-tyrosine kinase inhibitors （EGFR-TKIs） on cell proliferation， apoptosis， cancer stem cell （CSC） marker expression， and metabolism in non-small cell lung cancer （NSCLC） cells. MethodsThe anti-tumor effects of Scutellariae Radix and EGFR-TKIs （gefitinib or osimertinib） in NSCLC cells were evaluated using the cell counting kit-8 （CCK-8） and Annexin V-FITC/propidium iodide （PI） double staining apoptosis assay. The activity of Scutellariae Radix and EGFR-TKIs in three-dimensional （3D） cultures of NSCLC cells was assessed using the CellTiter-Glo® 3D cell viability assay. The mRNA and protein expression levels of CSC markers， sex determining region y box protein 2 （SOX2） and aldehyde dehydrogenase 1 family member A1 （ALDH1A1）， were detected by quantitative real-time polymerase chain reaction （Real-time PCR） and Western blot， respectively. Changes in intracellular reactive oxygen species （ROS） levels were detected by ROS staining， and the redox ratio was detected by femtosecond laser labeling free imaging （FLI）. ResultsUnder both two-dimensional （2D） and 3D culture conditions， compared with the blank group and EGFR-TKI group， the combination group showed significantly reduced cell viability and increased apoptosis rate （P<0.05）. Compared with the EGFR-TKI group， the mRNA and protein levels of CSC markers were significantly downregulated in the combination group （P<0.05）. Additionally， the redox ratio was significantly elevated （P<0.05）， and ROS levels were also increased in the combination group compared with the EGFR-TKI group. ConclusionIn NSCLC cells， Scutellariae Radix enhances the redox ratio and increases ROS levels， thereby inhibiting the expression of CSC markers and strengthening the anti-tumor effects of EGFR-TKIs. This provides a novel molecular mechanism by which Scutellariae Radix may enhance the sensitivity of targeted therapies.

Objective:To explore the effects of semaglutide on glucolipid metabolism and bone metabolism in patients with type 2 diabetes mellitus (T2DM).Methods:A total of 96 T2DM patients treated in the Second People′s Hospital of Hefei from May 2022 to May 2023 were divided into the study group (48 cases) and the control group (48 cases) by treatment methods. The patients in the study group were treated with semaglutide, and the patients in the control group were treated with metformin, respectively, they were treated for 12 weeks. The levels of glucolipid metabolism, body mass index (BMI), bone metabolism, serum levels of adipocytokine 13 (apelin-13), feeding inhibitory factor 1 (nesfatin-1) and chemerin were compared between the two groups before and after treatment, and the incidence of adverse reactions was recorded.Results:After treatment, the improvement of glucolipid metabolism index in the study group were better than those in the control group ( P<0.05). After treatment, the BMI in the study group was lower than that in the control group: (24.26 ± 1.08) kg/m 2 vs. (25.40 ± 1.36) kg/m 2, there was statistical difference ( P<0.05). After treatment, the levels of total type Ⅰ collagen amino terminal lengthening peptide (TPINP) and bone gla protein (BGP) in the study group were higher than those in the control group and β C-terminal telopeptide of type Ⅰcollagen (β-CTX) was lower than that in the control group: (48.50 ± 9.27) μg/L vs. (44.85 ± 8.20) μg/L, (20.73 ± 6.34) μg/L vs. (18.05 ± 6.20) μg/L, (0.30 ± 0.10) μg/L vs.(0.36 ± 0.08) μg/L, there were statistical differences ( P< 0.05). After treatment, the levels of serum apelin-13 in the study group was higher than that in the control group, while the levels of nesfatin-1 and chemerin were lower than those in the control group: (1 500.43 ± 153.36) ng/L vs. (1 350.24 ± 142.30) ng/L, (3.06 ± 0.65) μg/L vs. (3.75 ± 0.78) μg/L, (9.85 ± 2.46) μg/L vs. (11.37 ± 2.34) μg/L, there were statistical differences ( P<0.05). The incidence of adverse reactions between the two groups had no statistical difference ( P>0.05). Conclusions:Semaglutide can significantly improve glucolipid metabolism, bone metabolism, decrease BMI, nesfatin-1 and chemerin levels, and increase apelin-13 level in T2DM patients.

Purpose To explore the application and clini-copathological significance of molecular classification in endome-trial cancer(EC)of WHO(2020)tumors of the female repro-ductive system.Methods Sixty-two EC patients were collected and categorized into four subgroups,namely POLE mutation type,mismatch repair deficient(MMRd)type,non-specific molecular spectrum(NMSP)type,and p53 mutation type,based on WHO molecular classification tested by PCR and im-munohistochemistry.The correlation among four molecular sub-groups and their clinicopathological features were analyzed.Re-sults The molecular classification was distributed as follows:3(4.8％)cases were POLE-mutated,15(24.2％)cases MMRd,36(58.1％)cases NSMP and 8(12.9％)cases p53 abnormal expression.There were no significant differences a-mong POLE-mutated and infiltration depth,grade,lymph vascu-lar space invasion and other pathological factors such as lymph node metastasis and FIGO stage(P＞0.05).Among 15 patients with MMRd,the proportion of FIGO stage Ⅱ+Ⅲ significantly increased.One case showed abnormal overexpression of p53 pro-tein,while two cases showed complete loss of expression in MMRd subgroup.36 cases of NSMP were associated with low histopathological grade(Grade Ⅰ+Ⅱ)(P＜0.05),and no significant differences were observed among NSMP and other clinicopathological factors(P＞0.05).The p53 abnormal ex-pression in 8 cases was related to high histopathological grade(Grade Ⅲ)(P＜0.05),and the rate of lymph node metastasis and FIGO stage Ⅱ+Ⅲ significantly increased in patients with p53 abnormal expression,and although the difference was not statistically significant(P＞0.05).Conclusion The molecu-lar subgroups of EC have certain clinical application value,the cases with MMRd and p53 abnormal expression may have poor prognosis than these with POLE-mutated and NSMP.

Objective: To investigate the clinical effects of sinus elevation surgery and implant restorationdue to insufficient bone massafter tooth extraction in patients with odontogenic maxillary sinusitis (OMS) and to provide a reference for use in clinical practice. Methods: This study was reviewed and approved by the Ethics Committee, and informed consent was obtained from the patients. Forty-five teeth were extracted from patients with OMS in the maxillary posterior area (the study group). Sinus elevation and implantation were performed due to insufficient bone height in the implant area 6-8 months after tooth extraction in the study group. Forty-eight teeth were extracted from patients without "OMS" in the maxillary posterior area (the control group), and sinus elevation and implantation were performed due to insufficient bone height in the implant area 6-8 months after tooth extraction inthe control group. In the study group, 13 cases of discontinuous maxillary sinus floor bone and residual alveolar bone height of the maxillary sinus floor less than 4 mm were addressed with lateral wall sinus elevation, and the other 32 cases were addressed with crest-approach sinus elevation. In the control group, 8 cases of residual alveolar bone height less than 4 mm in the maxillary sinus floor were addressed with lateral wall sinus,and the other 40 cases were addressed with crest approach sinus elevation. Restorations were placed 6 to 8 months after surgery. The patients were followed up 21 days, 3 months, and 8 months after implantation and every 6 months after the placement of the restorations. The sinus bone gain (SBG), apical bone height (ABL) and marginal bone loss (MBL) were statistically analyzed 24 months after the restoration. Results: The average preoperative mucosal thickness in the 45 patients in the study group was (1.556 ± 0.693) mm, which was significantly larger than that in the control group (1.229 ± 0.425) mm (P<0.001). There were no perforations in either group. Twenty-four months after restoration, there was no significant difference in the SBG, ABH or MBL between the two groups (P>0.05). Conclusion After the extraction of teeth from patients with OMS, the inflammation of the maxillary sinus decreased, and the bone height and density in the edentulous area were restored to a certain degree. The effects of sinus floor lifting surgery and implant restoration do not differ between patients with and without OMS.

Objective To observe the value of B1 corrected T1 mapping for distinguishing pathological types and differentiation degrees of lung cancers.Methods A total of 74 lesions in 65 patients with lung cancers were prospectively enrolled,including 49 poorly differentiated lesions and 25 moderately or well differentiated ones,i.e.42 adenocarcinomas,14 squamous cell carcinomas and 18 small cell lung cancers(all poorly differentiated).B1 corrected T1 mapping was performed,ROI(ROI1 and ROI2)were delineated using 2 methods,and T1 values of different pathological types and differentiation degrees lung cancers were compared.The receiver operating characteristic(ROC)curves were drawn,and the areas under the curve(AUC)were calculated.Results Significant differences of T1 values were found among different pathological types of lung cancer(all P＜0.05),as well as between small cell lung cancer and the rest 2 types of lung cancer(both P＜0.05).There were significant differences of T1 values between poorly differentiated and moderately well differentiated lung cancer(squamous cell carcinoma+adenocarcinoma)(both P＜0.05).Taken ROI1 T1 value=1 524.21 ms as the cut-off value,the AUC of T1 value for distinguishing poorly differentiated and moderately well differentiated lung cancer(squamous cell carcinoma+adenocarcinoma)was 0.698,with sensitivity of 64.50％and specificity of 76.00％.Taken ROI2 T1 value=1 630.68 ms as the cut-off value,the AUC of T1 value was 0.676,with sensitivity of 54.80％and specificity of 80.00％.Conclusion B1 corrected T1 mapping was helpful for distinguishing pathological types and differentiation degrees of lung cancers.
