Objective To understand the application effect of early screening scale and behavioral intervention effect in children with autism spectrum disorder (ASD). Methods A total of 348 children with suspected ASD were selected and evaluated using the Modified Checklist for Autism in Toddlers (M-CHAT) and Autism Behavior Checklist (ABC). The evaluation results were compared with those from the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Children enrolled were given Early start Denver model (ESDM) intervention. The evaluation results of Gesell Developmental Scale and Autism Treatment Evaluation Checklist (ATEC) scores were compared before and after intervention. Results The sensitivity, specificity, accuracy and Kappa value of M-CHAT for evaluating ASD in children aged 1-3 years were 89.53%, 90.70%, 89.92% and 0.78. The corresponding values of ABC were 78.49%, 81.40%, 79.46% and 0.56. The sensitivity, specificity, accuracy and Kappa value of M-CHAT for evaluating children aged >3-6 years were 87.30%, 77.78%, 84.44% and 0.64. The corresponding values of ABC were 85.71%, 77.78%, 83.33% and 0.62. The sensitivity and accuracy of M-CHAT were higher than ABC for evaluating ASD in children aged 1-3 years (P<0.05). There were no significant differences in sensitivity, specificity and accuracy between M-CHAT and ABC for evaluating ASD in children aged 3-6 years (P>0.05). After intervention, development quotients (DQ) of personal-social aspects, adaptability, language, gross motor, and fine motor of children with ASD were higher than those before intervention (P<0.05). ATEC scores for language, behavior, sensation, and social contact of children with ASD were lower than those before intervention (P<0.05). Conclusion M-CHAT and ABC both can be used for early screening of ASD in children, especially M-CHAT. Early behavioral intervention can effectively improve the condition and developmental level of children with ASD.

Objective:To investigate the application effects of a novel framework: the external septal retention bionic framework in East Asian rhinoplasty.Methods:A retrospective analysis was performed based on the clinical data of the patients who received treatments in Department of Plastic and Aesthetic ( Burn) Surgery, the Second Xiangya Hospital, Central South University from January 2022 to July 2023 using an external septal retention bionic framework with autologous costal cartilage rhinoplasty. The patients were all treated with a V-shaped incision at the nasal columella, which continued to both sides of the nose to form a bird-shaped incision. During the operation, the sixth or seventh costal cartilage was sculpted to form the nasal columella support grafts (sturt), external nasal septal graft, cap grafts, and shield grafts, in which the nasal column support graft and external nasal septal graft were implanted in a mortise-and-tenon joint structure to form a septum bionic retained external stent in order to lengthen the nasal columellar column and strengthen the septum. A capsular graft was used to shape the tip of the nose and the rectus abdominis fascia was covered to soften the tip of the nose, and the shield grafts were used to fill out the subnasal lobules. A bulb was sculpted, shaped and implanted in the dorsal space to elevate the nasal dorsum. To observe the postoperative results and complications, a postoperative satisfaction survey was completed using the rhinoplasty outcome evaluation (ROE) and the visual analogue scale (VAS) with regular follow-up. Comparison of preoperative and postoperative scale scores was performed using paired samples t-test. Nasal stent stability was assessed by measuring the patients’ preoperative and postoperative nasolabial angle and nasal tip protrusion. The comparison of preoperative and postoperative nasolabial angle was performed using the paired-sample t-test, and the comparison of nasal tip protrusion was performed using the Wilcoxon signed rank-sum test, P<0.05 considered a statistically significant difference. Results:A total of 33 patients were enrolled, including 4 males and 29 females, with average age of 23.8 years(15-42 years). The follow-up period is (14.52 ± 4.72) months (3 to 21 months). Thirty-three patients recovered well after surgery, and no short-term complications such as infection or bleeding occurred. The patients' nasal aesthetic problems such as saddle nose, deviated nasal columella, bilateral asymmetry of the nose, bilateral nasal base depression, and rounded shield of the nasal tip were improved after surgery. Satisfaction survey results: ROE and VAS scores were significantly higher than those before surgery, which were [(17.92±2.56) vs.(12.78±3.14)] and [(8.08±1.66)vs(5.15±1.99)], ( P<0.05), 87.9% (27/33)of the patients were satisfied with the aesthetic and functional outcomes of the nose. Comparisons of nasolabial angle [(87.28±2.58)° vs. (97.64±1.95)°] and tip protrusion [1.88 (1.78, 1.95) cm vs. 2.16(2.01, 2.32) cm] measurements between preoperative and postoperative period of the 33 patients, the differences were statistically significant ( P<0.05). Conclusion:Rhinoplasty for East Asians employs an external septal retention bionic framework to retain the nasal septum. This technique can avoid septal cartilage resorption caused by compression of grafts transplanted in the future, and cause less damage to the anatomy and physiology of the nose. The framework is relatively easy to construct, with a stable and strong stent, and good patient satisfaction. It can achieve a more desirable aesthetic effect of the nose.

Objective:To investigate the surgical effect of pedicled upper lip mucosal flap in repairing nasal septal mucosal defects after rhinoplasty.Methods:A retrospective analysis was performed from January 2016 to October 2022, the clinical data of patients with nasal septal mucosal defects after rhinoplasty were collected in the Department of Plastic and Aesthetic (Burn) Surgery at the Second Xiangya Hospital of Central South University. The pedicled upper lip mucosal flap was utilized for repair based on the patient’s medical history and wound condition. The pedicle of the flap was designed 1 cm adjacent to the frenulum of the upper lip, and an appropriate flap was incised based on the size of the wound, with dissection performed up to the superficial layer of the orbicularis oris muscle. The dissection establishes an upper lip tunnel that connects the gingival-buccal groove to the nasal cavity. The pedicled upper lip mucosal flap was elevated and transposed into the nasal cavity via the upper lip tunnel. The position of the flap was adjusted to ensure complete coverage and fixation of the nasal septal defect wound using 5-0 absorbable suture. The visual analogue scale (VAS) and the nasal obstruction symptom evaluation (NOSE) scale were utilized to facilitate patients’ satisfaction evaluation and assessment of nasal obstruction symptoms before surgery and at 6 months post-surgery. The VAS total score was 10 points, with higher scores indicating greater levels of patient satisfaction. The NOSE scale comprises of 5 items, each assigned a score ranging from 0 to 4, denoting absence of symptoms, very mild presence, moderate intensity, relatively severe manifestation, and highly severe indication respectively. The measurement data of VAS and NOSE scores before surgery and at 6 months post-surgery was expressed by Mean±SD, using paired t-test. The score distribution of the NOSE scale was represented by the number of cases, using Mann-Whitney U test. Results:The study included a total of 15 female patients, with an average age of (27.6±2.9) years (ranging from 23 to 33 years). Eleven cases presented with preoperative cartilage exposure, and the size of tissue defect ranged from 0.9 cm×0.5 cm to 1.5 cm×0.7 cm. Nine patients had a history of smoking. Skin grafting was performed in 9 patients, while nasal mucosal metastasis was observed in 8 patients. The dimensions of the flap varied from 4.0 cm×1.2 cm to 7.0 cm×1.5 cm. The postoperative recovery was satisfactory, with successful survival of the skin flaps and no occurrences of infection, hematoma, wound dehiscence, or flap necrosis. The average duration of follow-up was (8.2±2.1) months (ranging from 6 to 12 months). The postoperative VAS score (7.73±0.88) was significantly higher compared to the preoperative score (1.86±0.74) ( P<0.01). Additionally, the postoperative NOSE score (4.66±1.71) showed a significant decrease from the preoperative score (10.73±2.68), with a statistically significant difference ( P<0.01). Among them, after surgery items of stuffy or unbreathable nose (2 cases vs. 15 cases), nasal obstruction (1 case vs. 14 cases), and feeling that the nose was not enough to breathe during exercise or exertion (4 cases vs. 14 cases) scored≥2 points were significantly less than those before operation (all P<0.01). Conclusion:The utilization of pedicled upper lip mucosal flap in the reconstruction of severe nasal septal mucosal defects following rhinoplasty has proven to be highly effective. The postoperative satisfaction of patients is remarkably high, the ventilation function exhibits significant improvement, and no severe complications are observed.

Objective To explore the correlations between image quality of prospective and retrospective electrocardiogram(ECG)-gated CT coronary angiogram and radiation dose in patients with different heart rates.Methods A total of 135 patients undergoing 256-slice spiral CT coronary angiography were enrolled in the study.Among them,66 cases received prospective ECG-gated scanning(prospective ECG-gated group)and further divided into two subgroups with heart rate≤80 beats/min(prospective ECG-gated+low heart rate subgroup,n=39)and>80 beats/min(prospective ECG-gated+high heart rate subgroup,n=27).The other 69 cases underwent retrospective ECG-gated scanning(retrospective ECG-gated group),including 45 cases with heart rate≤80 beats/min(retrospective ECG-gated+low heart rate subgroup)and 24 with heart rate>80 beats/min(retrospective ECG-gated+high heart rate subgroup).The baseline data,image quality[mean CT value,image noise,signal-to-noise ratio(SNR),subjective image quality score]and radiation dos[CT volume dose index(CTDIvol),dose length product(DLP),effective dose(ED)]were compared among 4 subgroups.The correlations of image quality with heart rate and radiation dose in prospective and retrospective ECG-gated groups were analyzed.Results The heart rates in prospective and retrospective ECG-gated+low heart rate subgroups were lower than those in prospective and retrospective ECG-gated+high heart rate subgroups(P<0.05).When comparing the mean CT value,image noise,SNR and subjective image quality score among 4 subgroups,no statistically significant differences were observed(P>0.05).The CTDIvol,DLP and ED in prospective ECG-gated+low heart rate subgroup were significantly lower than those in the other 3 subgroups(P<0.05),and the indicators in prospective ECG-gated+high heart rate subgroup were lower than those in retrospective ECG-gated group(including low and high heart rate subgroups)(P<0.05).Pearson correlation coefficient analysis revealed that the mean CT value,image noise,SNR,subjective image quality score had no significant correlation with heart rate,CTDIvol,DLP and ED in prospective and retrospective ECG-gated groups(P>0.05).Conclusion The subjective and objective image quality of 256-slice spiral CT coronary angiography is not correlated with radiation dose.Prospective ECG-gated scanning can reduce the radiation dose and ensure the image quality as compared with retrospective ECG-gated scanning.This holds true for eligible patients with high heart rate,and the former can effectively reduce radiation exposure.Therefore,prospective ECG-gated scanning is worthy to be promoted in clinic.

Background The course of schizophrenia is prolonged,and patients have impaired social function and significantly reduced quality of life.Drug therapy combined with psychological therapy is particularly important for improving the quality of life of patients.Brief cognitive behavioral therapy(BCBT)has been widely applied in clinical practice,but current research on BCBT focuses more on improving patients' symptoms and lacks relevant reports on improving quality of life.Objective To evaluate the efficacy and influencing factors of BCBT combined with conventional treatment on improving the quality of life in patients with schizophrenia.Methods A total of 210 patients who met the diagnostic criteria for schizophrenia in the International Classification of Diseases(10th edition)(ICD-10)and were followed up at the outpatient department of Beijing Anding Hospital Capital Medical University from August 2011 to December 2016 were selected.Using a random number table method,patients were divided into study group and control group,with 105 cases in each group.Both groups received routine treatment,and the research group received a total of 8 BCBT sessions for 12 weeks on this basis.At the baseline period and 12 weeks of treatment,26 weeks of follow-up and 52 weeks of follow-up,Positive and Negative Syndrome Scale(PANSS),Personal and Social Performance Scale(PSP)and World Health Organization Quality of Life Brief(WHOQOL-BREF)were used for evaluation.Results The results of repeated measures analysis of variance showed that the time point effect and interaction effect of PANSS total score were statistically significant(F=118.783,8.083,P<0.01).The time point effect,inter group effect and interaction effect of PSP total score were statistically significant(F=94.358,4.048,5.490,P<0.05 or 0.01).The time point effect,inter group effect and interaction effect of the total score of WHOQOL-BREF were all statistically significant(F=12.330,4.168,4.142,P<0.05 or 0.01)Binary Logistic regression analysis showed that the study group(OR=1.861,95%CI:1.004～3.448)and young age(OR=1.044,95%CI:1.001～1.088)were protective factors for improving quality of life of patients,while high PANSS baseline score(OR=0.972,95%CI:0.945～0.999)was a risk factor for improving quality of life of patients.Conclusion The combination of BCBT and conventional treatment has an earlier onset of improvement in the quality of life of patients with schizophrenia,and long-term efficacy is superior to conventional treatment.

Objective To study the effects of attenuated Salmonella(Ty21a-pIRES-IL-2-NK4,TPIN)carrying interleukin-2(IL-2)/4-kringle antagonist of hepatocyte growth factor(NK4)double gene on humoral and cellular immune function.Methods Eighteen BALB/c mice,half male and half female,were randomly divided into control group(1. 5 mL 10%NaHCO3 by gastric tube feeding),Ty21a group(0. 1 mL Ty21a by gastric tube feeding)and TPIN group(0. 1 mL TPIN by gastric tube feeding),with 6 mice in each group. The immunization was boosted twice 7 d after the initial immunization. At 21d after administration,the blood samples were collected from eyeballs and the serum was separated,which was detected for the serum IgG antibody level by ELISA. The thymus and spleen of mice were isolated aseptically,and the spleen cells were stimulated by Ty21a and TPIN respectively in vitro. After 72 h,the proliferation ability of spleen cells was measured by CCK-8 assay,and the expression level of cytokines in spleen cells was detected by ELISA. The spleen and thymus were weighed,the spleen and thymus indexes were analyzed,and HE staining was performed.Results Compared with the control group and Ty21a group,the serum IgG level(F = 111. 74,P < 0. 01)and the contents of IFNγ,IL-4 and IL-10 in spleen cell supernatant(F = 38. 21,11. 37 and 26. 92,respectively,each P < 0. 05)increased significantly,as well as the spleen and thymus indexes(F = 10. 419 and 5. 859,respectively,each P < 0. 05)showed significant increase. In mice of Ty21a and TPIN group,the thymus cortex widened,lymphocytes increased,and there was mild inflammatory reaction;the white pulp and lymphocytes in spleen increased with neutrophil infiltration.Conclusion TPIN has a good immune protective effect,and can significantly stimulate the body to produce humoral immunity and cellular immunity,which may have a good therapeutic effect on tumors.

ObjectiveTo construct traditional Chinese medicine （TCM） diagnostic scale of turbid toxin syndrome in order to provide corresponding reference for the standardization of TCM syndromes and studies. MethodsWe systematically searched the Chinese Medical Dictionary （CMD）， China Knowledge Network （CNKI）， Wanfang Data Knowledge Service Platform （WF） and VIP database for TCM classics and modern literature on turbid toxin syndrome， and initially screened the four diagnosis information of turbid toxin syndrome， established a pool of information entries， and conducted a cross-sectional clinical survey. Discrete trend method， correlation coefficient method， Cronbach's coefficient method， and factor analysis method were applied to objectively screen the entries. The diagnostic scale of turbid toxin syndrome were constructed through three rounds of Delphi method expert survey to determine the scale entries， using hierarchical analysis to get the judgement matrix scores and relative weight of each entry， after passing consistency test and then isometric expansion of the relative weight of the entries to get the weight of each entry and assign the value. ResultsA total of 35 articles were included， 45 entries were obtained after the initial screening. After the clinical investigation， 12 entries were not suitable by the discrete trend method， 23 entries not suitable by correlation coefficient method， 13 entries by the internal consistency screening were removed with the Cronbach's alpha coefficient rising， and 10 entries not suitable by the factor analysis method. Twenty-two entries were retained after objective screening by the combined use of the four statistical methods. The positive coefficients of experts in the three rounds of Delphi method of expert consultation were 96.67%， the coefficients of expert authority were 0.834， 0.856， and 0.867， and the coefficients of co-ordination were 0.126， 0.326， and 0.312， respectively. After consulting with clinical experts， and three rounds of Delphi method survey and hierarchical analysis method weight assignment， the diagnostic scale entries of turbid toxin syndrome were finally established. Primary symptoms： dark red or purple and dusky tongue， yellowish greasy or dry coating （10 points）； sticky and unpleasant stools （8 points）； disharmony of tastes including halitosis， sticky and greasy taste in the mouth， dry mouth and bitter taste in the mouth （6 points）； unfavourable or yellowish or red urination （5 points）； and dark complexion （4 points）. Secondary symptoms： heavy body （3 points）； dizziness （3 points）； profuse， sticky， foul-smelling secretions （2 points）； wiry and slippery， or slippery， or slippery and rapid pulse （2 points）； feeling of hardness in the abdomen （1 point）. ConclusionUsing Delphi method combined with the hierarchical analysis method， combining qualitative and quantitative study， a diagnostic scale of turbid toxin syndrome was initially developed.
