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 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.

Objective:To explore the properties of gelatin-polyethylene glycol hydrogel loaded with silver nanoparticle (AgNP) Chlorella (hereinafter referred to as the composite hydrogel) and its effects on healing of infected full-thickness skin defect wounds in mice. Methods:The research was an experimental research. The simple gelatin-polyethylene glycol hydrogel (hereinafter referred to as the simple hydrogel) and the composite hydrogel were prepared, and the appearance and injectability of the two hydrogels were observed at 55 and 37 ℃, and under the irradiation of 808 nm near-infrared light, respectively. An electronic universal testing machine was employed to assess the tensile and compressive stress-strain properties of both types of hydrogels at room temperature. Additionally, the cyclic compressive stress-strain properties of the composite hydrogel were examined at 80% of the maximum compressive stress. Staphylococcus aureus or Escherichia coli solution was added to phosphate buffer solution (PBS), simple hydrogel, and composite hydrogel, respectively. The part of composite hydrogel containing Staphylococcus aureus or Escherichia coli solution was irradiated with near-infrared light for 5 minutes. After each sample was incubated for 6 h, the dilution plating method was used to detect and calculate the mortality rates of the two bacteria at 24 h of culture ( n=5). The discarded foreskin tissue was taken from a 6-year-old healthy boy admitted to the Department of Urology of the First Affiliated Hospital of Naval Medical University for circumcision. Primary human fibroblasts (HFbs) were isolated using the enzyme extraction method, routinely cultured to the 3 rd to 6 th passages for subsequent cellular experiments. Composite hydrogel extracts with final mass concentrations of 100.0, 50.0, 25.0, 12.5, and 0 mg/mL were respectively prepared and used to culture HFbs, and the cell proliferation after 24 h of culture was detected using a cell counting kit 8 ( n=3). A total of twenty 6-8 weeks old C57BL/6J female mice were utilized, and a full-thickness skin defect was surgically created on the back of each mouse. The wounds were infected with Staphylococcus aureus solution. The infected mice were divided into blank control group, simple hydrogel group, composite hydrogel group, and combined treatment group according to the random number table, and the wounds were treated with PBS, simple hydrogel, composite hydrogel, and composite hydrogel+light irradiation (under the irradiation of 808 nm near-infrared light for 5 min), respectively, with 5 mice in each group. On post injury day (PID) 0 (immediately after the first wound treatment), 3, 7, and 14, an overall assessment of wound exudation and healing were conducted, and the wound healing rates on PID 7 and 14 were calculated ( n=5). On PID 14, hematoxylin-eosin staining was performed to observe histopathological changes in the mouse wound. Results:Both simple hydrogel and composite hydrogel were in a solution state at 55 ℃ and transition to a gel state when cooling to 37 ℃. After the two hydrogels were irradiated by near-infrared light, only the composite hydrogel reheated up and returned to the solution state again with injectability. The maximum tensile stress of the composite hydrogel was up to 301.42 kPa, with a corresponding strain of 87.19%; the maximum compressive stress was up to 413.79 kPa, with a corresponding strain of 91.67%, which was similar to the tensile and compressive properties of the simple hydrogel. After 10 compression cycles, the maximum compressive stress of the composite hydrogel still reached 84.1% of the first compressive stress. After 24 h of culture, the mortality rate of Staphylococcus aureus treated with simple hydrogel was significantly higher than that treated with PBS ( P<0.05); the mortality rates of Escherichia coli and Staphylococcus aureus treated with composite hydrogel alone were significantly higher than those treated with simple hydrogel ( P<0.05); the mortality rates of Escherichia coli and Staphylococcus aureus treated with composite hydrogel+light irradiation were significantly higher than those treated with composite hydrogel alone ( P<0.05). After 24 h of culture, compared with that cultured in composite hydrogel immersion solution with final mass concentration of 0 mg/mL, the proliferation activity of HFbs cultured in composite hydrogel immersion solution with final mass concentrations of 25.0 and 50.0 mg/mL was significantly enhanced ( P<0.05), while the proliferation activity of HFbs cultured in composite hydrogel immersion solution with final mass concentration of 100 mg/mL was significantly decreased ( P<0.05). On PID 0 and 3, more purulent secretions were seen in the wounds of mice in blank control group and simple hydrogel group, while only a small amount of exudate was observed in the wounds of mice in composite hydrogel group, and no obvious infection was observed in the wounds of mice in combined treatment group. On PID 7 and 14, the wound healing rates of mice in simple hydrogel group were significantly higher than those in blank control group ( P<0.05); the wound healing rates of mice in composite hydrogel group were significantly higher than those in simple hydrogel group ( P<0.05); the wound healing rates in combined treatment group were significantly higher than those in composite hydrogel group ( P<0.05). On PID 14, the wounds of mice in blank control group exhibited a high infiltration of inflammatory cells with no new epithelial layer observed; the wounds of mice in simple hydrogel group displayed a short length of newly formed epithelium with a small amount of inflammatory cells; the wounds of mice in composite hydrogel group exhibited continuous formation of new epithelium and a large amount of immature granulation tissue; the wounds of mice in combined treatment group showed continuous epithelialization with less immature granulation tissue. Conclusions:The prepared composite hydrogel exhibits excellent thermosensitivity, photothermal properties, and injectability, as well as excellent mechanical properties, antibacterial properties, and biocompatibility, and can promote the healing of infected full-thickness skin defect wounds in mice.

Objective To compare the value of stack-of-stars-volumetric interpolated breath-hold examination(Star-VIBE)and T1-volumetric interpolated breath-hold examination(T1-VIBE)MRI for displaying peripheral lung cancer.Methods Fifty-two patients with 56 peripheral lung cancer were prospectively enrolled,and chest Star-VIBE and T1-VIBE MRI were acquired.The morphological features were observed,and the subjective scores were recorded.The maximum diameter,signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of lesions were measured based on Star-VIBE and T1-VIBE MRI,respectively.Taken CT as the references,the value of Star-VIBE and T1-VIBE MRI for displaying peripheral lung cancer were compared.Results Star-VIBE MRI had higher scores for displaying spiculation sign,lobulation sign,pleural depression sign and halo sign than T1-VIBE(both P＜0.05).CNR and SNR of Star-VIBE MRI were significantly higher than those of T1-VIBE(both P＜0.001).No significant difference of the maximum diameter of lesions measured based on Star-VIBE and T1-VIBE MRI compared with CT was found,nor between Star-VIBE and T1-VIBE MRI(all P＞0.05).Conclusion Star-VIBE MRI had better value for displaying peripheral lung cancer than T1-VIBE.

Objective:To investigate the factors that influence the occurrence of complications following deep inferior epigastric perforator (DIEP) flap breast reconstruction, and to determine whether these complications have an impact on the patient's quality of life.Methods:The clinical and follow up data from patients who underwent DIEP flap breast reconstruction at the Department of Breast, Affiliated Cancer Hospital of Zhengzhou University from Dec 2019 to Mar 2023 were retrospectively analyzed.Results:A total of 85 patients underwent DIEP flap breast reconstruction, including 71 stage Ⅰ reconstructions and 14 stage Ⅱ reconstructions. Postoperative complications occurred in 22 cases 25.9%, including flap complications in 11 cases (12.9%) and abdominal donor site complications in 11 cases (12.9%). Univariate and multivariate analyses showed that the overall incidence of complications was associated with high BMI and early surgery ( P<0.05). Flap complications were associated with high BMI, surgery performed at initial phase, and the use of internal mammary vascular branches as recipient vessels ( P<0.05). Abdominal complications were associated with previous abdominal surgery scars ( P<0.05). BREAST-Q scores showed no significant differences between the surgical complication group and the no complication group in terms of breast satisfaction, mental health, physical health-chest, physical health-abdomen, satisfaction with abdomen, sexual health, etc. ( P>0.05). Conclusions:DIEP flap breast reconstruction has a significant learning curve. The patient's own clinical characteristics (such as BMI and abdominal incision scars) and intraoperative choices (such as the selection of recipient vessels) may influence the occurrence of postoperative complications. However, the presence of postoperative complications does not appear to have an impact on patient-reported outcomes.

ObjectiveTo compare and observe the effect of Reduning injection （mainly clearing heat）， Shenfu injection （mainly warming Yang） combined with gefitinib on the proliferation， apoptosis， stemness characteristics and metabolism of lung cancer cells. MethodDifferent non-small cell lung cancer （NSCLC） cell lines were selected and intervened with gefitinib （5， 10， 20 μmol·L^-1）， Reduning injection （0.6%， 0.9%）， Shenfu injection （0.6%， 0.9%）， gefitinib combined with Reduning injection， and gefitinib combined with Shenfu injection. Cell proliferation in each group was detected by cell counting kit-8 （CCK-8） assay， and cell apoptosis was detected by flow cytometry. The mRNA and protein expressions of lung cancer stem cell markers sex determining region Y-box 2 （Sox2） and aldehyde dehydrogenase family 1 member A1 （ALDH1A1） were determind by real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. The redox ratio of lung cancer cells was observed by femtosecond label-free imaging （FLI） and energy metabolism instrument was used to determine the glycolysis level in cells. ResultCompared with the blank group， Reduning injection reduced the survival rate of lung cancer cells （P<0.05）， increased the apoptosis rate （P<0.05）， down-regulated the mRNA and protein expressions of Sox2 and ALDH1A1 （P<0.05）， and up-regulated the redox ratio of cells （P<0.05）， while Shenfu injection exerted no remarkable effect on the above indexes. In addition， compared with gefitinib alone， Reduning injection combined with gefitinib inhibited the survival rate of lung cancer cells （P<0.05）， promoted the cell apoptosis （P<0.05）， down-regulated the mRNA and protein expressions of Sox2 and ALDH1A1 （P<0.05）， up-regulated the redox ratio of cells （P<0.05）， and lowered the proton efflux rate of glycolysis （P<0.05）， while Shenfu injection combined with gefitinib failed to affect these indexes of lung cancer cells significantly. ConclusionReduning injection may inhibit stemness characteristics of tumor cells by regulating their metabolism to enhance the proliferation-inhibiting and pro-apoptotic effects of gefitinib on lung cancer cells， while Shenfu injection had no significant enhancing effect on gefitinib. This indicates that epidermal growth factor receptor tyrosine kinase inhibitors （EGFR-TKIs） should be used in combination with heat-clearing Chinese medicines.

Objective To investigate the relationship between atrial fibrillation and left heart structure change in patients with hemodialysis combined with hemoperfusion.Methods A total of 60 patients with end-stage renal disease who underwent hemodialysis combined with hemoperfusion treatment in Ganzhou Hospital of Traditional Chinese Medicine from December 2020 to December 2021 were selected.Thirty patients with atrial fibrillation were included in observation group,and thirty patients without atrial fibrillation were included in control group.The left heart structure indexes of two groups were compared,and the relationship between atrial fibrillation and left heart structure change in patients with hemodialysis combined with hemoperfusion was analyzed.Results Left ventricular end diastolic diameter(LVEDD),left ventricular end systolic diameter(LVESD),left atrium diameter(LAD),interventricular septal thickness(IVST),and left ventricular posterior wall thickness(LVPWT)in observation group were higher than those in control group,and left ventricular ejection fraction(LVEF)was lower than that in control group(P<0.05).Logistic regression analysis showed that the decrease of LVEF and the increase of LVEDD,LVESD,LAD,IVST and LVPWT were associated with atrial fibrillation in patients with hemodialysis combined with hemoperfusion(P<0.05).The results of receiver operating characteristic curve showed that area under the curve of LVEDD,LVESD,LAD,LVEF,IVST and LVPWT in diagnosing atrial fibrillation in patients with hemodialysis combined with hemoperfusion were 0.724,0.708,0.760,0.761,0.762 and 0.758,respectively,which had certain diagnostic value.Conclusion Atrial fibrillation in patients with hemodialysis combined with hemoperfusion is related to the change of left heart structure,and the left heart structure indexes are helpful to assist the diagnosis of atrial fibrillation.

Objective:To evaluate the safety and efficacy of belimumab(BLM) in patients with SLE.Methods:Clinical data were collected for SLE patients who were diagnosed and treated with BLM in the Department of Rheumatology and Immunology (inpatient and outpatient department) of Guilin Medical College Affiliated Hospital from 1 December, 2019 to 12 May, 2023. BLM + standard of care (SOC) for the BLM group and SOC only for the SOC group. The primary clinical endpoint was adverse events (AE) occurring in groups, and the secondary clinical endpoint was disease activity index including SLEDAI-2000, clinical indicators, glucocortoid dosage reduction, and disease flare in the two groups. Propensity score matching method, independent sample t-test, non-parametric rank-sum test, variance analysis were used for statistical analysis. Results:Among the 79 BLM patients included, 48 had hematological impairment (61%), 53 had renal impairment (67%), 11 had skin and mucosal impairment (14%), 20 had joint impairment (25%), and 2 had neurological impairment(3%). There were no serious adverse events during the treatment in both groups. In the BLM group, with 14 cases experienced respiratory system infection, 1 with urinary system infection, 3 with skin infection, 4 with herpes virus infection, and 16 with liver function impairment. In the SOC group, there were 26 cases experienced respiratory system infection, 1 with urinary system infection, 6 with digestive system symptoms, 6 with skin infection, 4 with herpes virus infection, 10 with liver function impairment, 2 with thrombosis, and 1 with sepsis. Patients tolerated BLM generally well, with fewer adverse events occurring [in patients with the long course treatment, the number of AE cases in the BLM group vs SOC group 11 [(33%) vs 22 (68%), ( χ2=3.74, P=0.053)]. From all study groups and high-dose glucocorticoid (≥20 mg) groups, it was observed that the BLM group had a more significant reduction in glucocortoid dose [baseline glocucorticoid reduction in the BLM group decreased from 20 (12, 40)mg/d to 6 (4, 10)mg/d ( Z=0.12, P=0.01). In the renal injury group, after treatment, serum creatinine level decreased in the BLM group glomerular filtration rate increased from 72.37 (41.97, 95.74) to 97.03 (71.18, 114.34) ( Z=-4.62, P<0.001). There was less flares in the BLM group [7 cases (28%) vs 18 cases (72%), χ2=5.58, P=0.018] when compared with the soc group. Conclusion:BLM is safe and effective for the treatment of SLE, which can reduce disease activity, improve clinical parameters, reduce glocucorticoid dosage, and have a low flare rate.
