Objective:To explore the mediating role of working memory (WM) in the cortisol-awakening response (CAR) and multiple object tracking (MOT) in children with attention deficit hyperactivity disorder (ADHD).Methods:92 children with ADHD (ADHD group) and 94 typically developing children (control group) were selected from January 2022 to October 2022. Salivary cortisol levels were detected and analyzed in all children at four time points after awakening. Children's WM and MOT performance were assessed by the 1-back and MOT paradigms, respectively. SPSS 26.0 software was used for t-test and Pearson correlation analysis of the data, and plug-in PROCESS model 4 of SPSS 26.0 was used for mediated effects analysis. Results:(1) ADHD group showed significantly lower CAR, 1-back accuracy and MOT performance((30.97±5.63), (81.33±10.64) %, (2.36±0.37)) than the control group((32.41±3.48), (91.19±7.12) %, (2.62±0.28))( t=-2.09, -7.22, -5.31, all P<0.05). (2) Pearson analysis showed that CAR was positively correlated with 1-back accuracy ( r=0.293, P<0.01) and MOT performance ( r=0.740, P<0.01). 1-back accuracy was positively correlated with MOT performance ( r=0.368, P<0.01). (3) WM partially mediated the effect of CAR on MOT in children with ADHD, accounting for 6.13% (0.003/0.049) of the total effect. Conclusion:Children with ADHD have deficits in MOT.WM plays a mediating role between CAR and MOT performance in children with ADHD.

Currently， there are many difficulties in formulating recommendations of traditional Chinese medicine （TCM） clinical practice guidelines. This paper analyzed and summarized the unique or prominent difficult issues in the formulation of recommendations faced by TCM guidelines， such as experts' professional background and experience bringing about the preferance from the academic emotion， inconsistency between different academic schools making it difficult to reach consensus， lack of guiding principles of the decision weight of different dimensions for recommendations. Therefore， methodological suggestions have been put forward， including organizing parallel TCM and western medicine consensus group， improving the method of combining TCM and western medicine paradigm， attaching great importance to the evidence-based governance of academic schools， and promoting the research on different dimensions for recommendation formulation， which may provide a methodological reference for the guideline development.

Objective To investigate the effect of electroacupuncture preconditioning on microglia polarization in rats after cerebral ischemia reperfusion(IR)injury and explore the role of tyrosine kinase 2(J AK2)/signal transducer and activator of transcription 3(STAT3)pathway in the process.Methods Forty-five clean-grade healthy male Sprague-Dawley rats were randomly and equally divided into sham operation group,IR group and electroacupuncture preconditioning group.Rat model of IR injury was induced with thread occlusion of the internal carotid artery.Before modeling,electroacupuncture preconditioning was applied to Baihui acupoint for 5 consec-utive days in the preconditioning group,and exposure of the cervical blood vessels were inflicted in the sham-operation group.At 24 h after reperfusion,the severity of neurological deficit was observed by modified neurological deficit score(mNSS),and the cerebral infarct volume was observed by TTC staining.Western blotting was used to detect the protein levels of classical acti-vated type(M1)marker inducible nitric oxide synthase(iNOS),alternative activated type(M2)marker arginase 1(Arg-1),JAK2 and p-JAK2,and STAT3 and p-STAT3,and q-PCR was applied to detect the mRNA expression of iNOS and Arg-1.The expression of TNF-α and IL-10 was measured by ELISA.Results Compared with the sham operation group,the mNSS,infarct vol-ume,protein levels of p-JAK2/JAK2,p-STAT3/STAT3,protein and mRNA levels of iNOS and Arg-1,and expression of TNF-α and IL-10 were significantly increased in the IR and electroacu-puncture preconditioning groups(P＜0.01).The preconditioning group had obviously lower mNSS,smaller infarct volume,decreased protein levels of p-JAK2/JAK2,p-STAT3/STAT3,re-duced protein and mRNA levels of iNOS,and declined TNF-α expression,but elevated expression of Arg-1 at protein(2.0±0.2 vs 1.5±0.1)and mRNA(4.2±0.8 vs 3.1±0.3)levels and increased IL-10 expression(49.1±7.1 pg/mg vs 27.9±5.9 pg/mg)when compared with the IR group(P＜0.01).Conclusion Electroacupuncture preconditioning can promote the polarization of microglia to M2 and inhibit the polarization of microglia to M1 after cerebral IR injury,which may be relat-ed to the inhibition of JAK2/STAT3 pathway.

Objective To establish a scientific training program that takes into account both anaerobic and aerobic training for pilots,and to explore the appropriate ratio of aerobic and anaerobic training.Methods According to the physical examination standards for pilots,a total of 16 healthy subjects aged 18-24 were selected from two batches.The two batches of subjects were trained with different aerobic and anaerobic ratios.Training period was 3 months.The changes in cardiopulmonary function of the subjects before and after training were evaluated using the cardiopulmonary function exercise testing system(CPET),and the changes in anaerobic capacity were evaluated using changes in strength as an indicator.Results After training,the weight load of the subjects in the two training programs,including barbell squats,leg flexion and hard pull,and barbell under 10RM and 3RM,was significantly increased(P<0.001),and there was no statistically significant difference in anaerobic strength growth between the two groups.The results of CPET showed that the maximum load,maximum heart rate,and respiratory quotient in the two groups were significantly increased after than before the training(P<0.01).The maximum load(Experiment group 1:29.12±19.69,Experiment group 2:72.00±46.24)and respiratory quotient(Experiment grouop 1:0.11±0.09,Experiment group 2:0.28±0.16)of the subjects in experiment group 2 before and after training were greater than those in experiment group 1.The difference was statistically significant(P<0.05).Conclusion The anaerobic and aerobic capacities of the subjects in the experiment group 2 are effectively improved,indicating that ratio of aerobic and anaerobic of the training scheme is better.

Objective To understand the carrying situation and common variation of pathogenic genes of single gene hereditary disease in childbearing age population in Anhui province,to explore the establishment of clinical application network and referral model of carrier screening in Anhui province,and to explore the application value of expansible carrier screening(expanded carrier screening,ECS)in clinic.Methods Samples were collected from 604 individuals of childbearing age,all exhibiting a normal phenotype and a family history of inherited dis-ease.These samples were obtained during the first trimester or early stages of pregnancy(≤13+6 weeks).Based on high-throughput sequencing and special PCR analysis techniques,pathogenic variants associated with 220 disea-ses were detected,and related genes were detected in the spouses of positive carriers.Results As of May 16,2023,604 tested samples had been collected,and 340 carriers of the target disease had been detected;The posi-tive rate of pathogenic variation detection was 56.29％ ;A total of 499 pathogenic variants were detected,with each tested individual carrying 0-5 variants;216 cases,accounting for 35.76％ ,carried a single gene recessive dis-ease pathogenic variation,which was the most common.There were 95 cases carrying two types of single gene re-cessive genetic disease pathogenic variation,accounting for 15.73％ .As of now,302 couples have been reported,and a total of 7 high-risk couples have been found through screening,with a high-risk rate of 2.32％ .There are a total of 5 pairs with autosomal recessive genetic pattern(both spouses carry the same pathogenic gene),and 2 pairs with X-linked genetic pattern(the female carries the X-linked pathogenic gene).Conclusion In this study,we obtained the overall carrier and clinical application of target diseases as well as the carrier rates of causative genes of common single-gene genetic diseases in 604 subjects who underwent ECS testing,which could provide scientific guidance for the establishment of a clinical application network and referral model for carrier screening in Anhui Province.

This experiment aims to investigate the effects of a dietary supplement of herbal tea resi-due on white feather broilers in the prospectives of growth performance,serum indexes and intesti-nal immune indexes.A total of 280 1-day-old white feather broilers with similar body mass and good health were randomly divided into 4 groups with 5 replicates per group and 14 birds per repli-cate.Group Ⅰ(control group)was fed a basal diet.Groups Ⅱ,Ⅲ and Ⅳ were fed a diet supple-mented with 2％,4％and 6％herbal tea residue powder,respectively.The feeding lasted for 49 days,and was divided into 2 phases from 1 to 21 days of age and 22 to 49 days of age.Blood,tissue and mucosa of the duodenum and jejunum were collected on 21 d and 49 d.Total cholesterol(T-CHO),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C)and the activities of aspartate aminotransferase(AST)and alanine amin-otransferase(ALT)in the serum were examined.The villus height and crypt depth of the jejunum were observed and measured by morphology.The mRNA expression levels of intestinal interleukin-1β(IL-1β),interleukin-2(IL-2),interleukin-4(IL-4),interleukin-10(IL-10)and tumor necrosis factor-α(TNF-α)were determined by qPCR.The results showed that compared with group Ⅰ,the mass of group Ⅲ on 21 d and 49 d significantly increased(P＜0.05).The average daily feed intake of 22-49 d and 1-49 d significantly increased(P＜0.05).The average daily mass gain of 1-21 d,22-49 d and 1-49 d significantly increased(P＜0.05).In the serum of 21 d,compared with group Ⅰ,T-CHO in group Ⅱ significantly decreased(P＜0.05).TG in groups Ⅱ,m and Ⅳ significantly de-creased(P＜0.05).LDL-C and AST activity in group Ⅳ significantly decreased(P＜0.05).In the serum of 49 d,T-CHO in group Ⅲ,LDL-C in group Ⅳ,HDL-C of groups Ⅲ and Ⅳ significantly increased(P＜0.05),and the ALT activity of these two groups decreased(P＜0.05).AST activity in group Ⅱ significantly decreased(P＜0.05).In the duodenum of 21 d,compared with group Ⅰ,the expressions of TNF-α in group Ⅱ was significantly decreased(P＜0.05).In the duodenum of 49 d,the expression of IL-10 in group Ⅱ was significantly increased(P＜0.05),and the expression of IL-2 in groups Ⅲ and Ⅳ was significantly decreased(P＜0.05).In the jejunum of 49 d,the ex-pression of IL-10 in group Ⅱ was increased(P＜0.05),and the expression of IL-2 in groups Ⅲand Ⅳ was significantly decreased(P＜0.05).In conclusion,dietary herbal tea residue can regulate circulating lipid level and enhance intestinal immunity of white feather broilers without affecting their normal growth performance.This experiment also suggested that the a 2％-4％supplementa-tion of herbal tea residues to white feather broilers was of good effect.

Objective:To analyze the value of 68Ga-fibroblast activation protein inhibitor (FAPI)-04 PET/CT in the detection of myocardial injury in patients treated with anti-tumor therapy. Methods:A retrospective study was conducted on 164 patients who underwent 68Ga-FAPI-04 PET/CT to evaluate the efficacy of anti-tumor therapy in Renji Hospital, School of Medicine, Shanghai Jiao Tong University between August 2021 and March 2024. The patients were divided into 68Ga-FAPI-04-positive group ( n=63, 36 males, 27 females, age (66.7±9.6) years) and 68Ga-FAPI-04-negative group ( n=101, 42 males, 59 females, age (55.2±14.1) years) based on the uptake of left ventricular myocardium (LVM). Moreover, FAPI-04 uptake was analyzed based on different types and locations, and the corresponding SUV max differences were analyzed by Kruskal-Wallis rank sum test. The differences of SUV max between 68Ga-FAPI-04-positive group and 68Ga-FAPI-04-negative group were analyzed by Mann-Whitney U test. The clinical factors such as gender, age, body mass index (BMI), previous history of coronary heart disease, left ventricular ejection fraction (LVEF), smoking history, hypertension, diabetes, cancer types and immune checkpoint inhibitors (ICIs) treatment were collected, and their predictive values for LVM 68Ga-FAPI-04 uptake were investigated by the binary logistic regression analysis. Results:Fifty patients of the 68Ga-FAPI-04-positive group (79.4%, 50/63) showed focal uptake of LVM, 7 patients (11.1%, 7/63) showed multifocal myocardial uptake, and 6 patients (9.5%, 6/63) showed diffuse myocardial uptake. A total of 127 uptake lesions were found, and most of them were located in the septum (37.8%, 48/127). The SUV max of LVM in 68Ga-FAPI-04-positive group and 68Ga-FAPI-04-negative group were 4.00(3.10, 5.40) and 1.31(1.20, 1.40) respectively ( z=-10.82, P<0.001). Differences of the SUV max among focal uptake group, multifocal myocardial uptake group, and diffuse myocardial uptake group were not significantly different (4.00(3.00, 5.10) vs 7.60(3.60, 9.30) vs 3.95(3.05, 5.05); H=3.81, P=0.149). There is no statistically significant difference either in FAPI uptake among different sites of LVM ( H=1.51, P=0.825). Age, previous history of coronary heart disease, BMI, LVEF and ICIs treatment were independent predictive factors for positive 68Ga-FAPI-04 uptake in the LVM (odds ratio ( OR) values: 0.87-10.43, all P<0.05). Conclusion:68Ga-FAPI-04 PET/CT is a potential new imaging method for the visualization of myocardial injury in patients with anti-tumor therapy.

Syndrome differentiation and treatment is a unique mode of diagnosis in traditional Chinese medicine （TCM）. The establishment of scientific and standardized syndrome diagnosis standards is an important link to evaluate the clinical efficacy of TCM objectively and systematically， and also a prerequisite for the promotion and development of TCM to obtain international recognition. This article reviewed the basic modes and existed problems of the current syndrome diagnosis criteria， and proposed to construct a multidimensional core information set integrating the minimized core symptoms， the artificial intelligence signs， the multi-modal laboratory indicators， and multi-omics specific markers， so as to present syndrome characteristics from multiple perspectives systematically. This paper also described the basic mode， constructure， as well as the process and methodology to be adopted in the establishment of the standardized diagnostic research method. The core information set of diagnostic symptoms not only took into account the specificity of the disease， but also improved the inconsistency due to the complexity and subjectivity of the syndrome differentiation， thereby providing a methodological basis for the standardization of TCM syndrome differentiation in clinical research.

Abstract: Objective　To investigate the molecular characteristics and drug resistance of Staphylococcus aureus (SA) isolated from wounds of paatients with orthopedic trauma, and analyze the molecular subtyping, virulence genes and drug resistance of SA in wounds of patients, so as to provide reference for the prevention and treatment of wound SA infection in patients. Methods　From January 2020 to June 2022, a total of 128 SA isolates were collected from wound specimens of orthopedic trauma patients at Wuxi 9th People's Hospital Affiliated to Soochow University. Methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible Staphylococcus aureus (MSSA) were differentiated using PCR. Multilocus Sequence Typing (MLST), staphylococcal protein A (spa), staphylococcal chromatoidal cassette mec (SCCmec), and accessory gene regulator (agr) typing were performed to determine the molecular typing and presence of virulence genes and drug resistance profiles. Results　Among the 128 SA isolates, 76 (59.38%) were MRSA and 52 (40.62%) were MSSA. MRSA typing showed that, MLST was dominated by ST59 (46 strains, 60.53%), spa was dominated by t437 (52.63%), SCCmec was dominated by Ⅰ (42.11%) and Ⅳ (39.47%). MSSA typing showed that, MLST was dominated by ST188 (30.77%), spa was dominated by t189 (61.54%), agr was dominated by Ⅰ (53.85%). In MLST typing, ST59 of MRSA was higher than that of MSSA, and ST188 and ST6 of MRSA were lower than those of MSSA (χ2=36.207, 20.227, 9.984, P<0.05). In spa typing, the t437 of MRSA was higher than that of MSSA, and the t189 of MRSA was lower than that of MSSA (χ2=18.276, 32.781, P<0.05). The virulence genes showed that, the detection rates of hlb and seb in MRSA were higher than those in MSSA (χ2=47.838, 10.261, P<0.05), and the detection rates of cna and ebpS in MRSA were lower than those in MSSA (χ2=26.176, 8.305, P<0.05). Drug susceptibility test showed that, and the drug resistance rates of MRSA and MSSA to vancomycin (VAN) and linezolid (LNZ) were 0. The drug resistance rates of MRSA to oxacillin (OXA), ERY and CLI were 86.84%, 68.42% and 76.32%, which were higher than corresponding 7.69%, 42.31% and 46.15% of MSSA (χ2=78.055, 8.623, 12.200, P<0.05). The analysis of multi-drug resistant strains (MDR) showed that 76 MRSA strains were MDR strains, and 12 of 52 MSSA strains (23.08%) were MDR strains. Conclusions　The molecular characteristics of SA isolated from orthopedic trauma patients' wounds were predominantly associated with MRSA strains of ST59-t437-SCCmec Ⅰ/Ⅳ-MRSA and ST188/ST6-t189-agr Ⅰ. These strains showed higher resistance to oxacillin, erythromycin, clindamycin, and higher susceptibility to vancomycin and linezolid. Such characteristics were closely related to the carriage of virulence genes. Clinicians should pay attention to the presence of MDR MSSA and develop appropriate antimicrobial strategies based on SA's molecular characteristics and antimicrobial resistance.
