Objective: To understand the correlation between autistic traits in children with autism spectrum disorder(ASD) and their parental behaviors, so as to provide evidence for improving social behavior in children with ASD. Methods: A total of 62 children aged 4-7 years diagnosed with ASD at Guangdong Provincial Work Injury Rehabilitation Hospital and Guangzhou Yuexiu District Children s Hospital from October 2021 to May 2025 were selected as the ASD group. A random number table method was used to select 62 healthy children of the same age from 3 ordinary kindergartens in Guangzhou as the control (typically developing,TD) group. The Parental Behavior Inventory and Social Responsiveness Scale were used to evaluate parental behaviors and autistic traits in both groups. The t-test and multiple linear regression were used to analyze the relationship between autistic traits in children with ASD and parental behaviors. Results: Compared with the TD group, the ASD group had significantly higher scores in social awareness, social cognition, social communication, social motivation, autistic behavior patterns, and the total score of social responsiveness, with statistically significant differences ( t =35.83, 46.17, 64.36, 41.45, 49.46,101.15, all P <0.01). The score of parental support/participation in the ASD group (24.61±4.30) was lower than that in the TD group (31.27±4.58), while the score of parental hostility/coercion in the ASD group (25.51±2.72) was higher than that in the TD group (12.75±2.72), with statistically significant differences ( t = -8.34, 26.14, both P <0.01). The total score of the Social Responsiveness Scale was negatively correlated with the dimension score of parental support/participation behaviors, and positively correlated with the dimension score of parental hostility/coercion behaviors ( r =-0.60, 0.91,both P <0.05). After adjusting for covariates such as children s age, gender, and primary caregiver, ASD children with exclusive breastfeeding ( β =-8.79) and parental support/participation behaviors ( β = -0.79 ) had a lower risk of autistic traits, while children with parental hostility/coercion behaviors ( β =4.62) had a higher risk of autistic traits (all P <0.05). Conclusion Autistic traits in children with ASD may be related to their parental behaviors and early feeding mode.

Objective To develop a new biological age model based on the National Health and Nutrition Examination Survey(NHANES)database and evaluate its predictive performance for mortality outcomes.Methods After excluding pregnant women and those with incomplete clinical data,a total of 8 234 participants aged 20～79 years from NHANES 2007-2010 were included and assigned into a testing set,and another 17 522 non-pregnant participants(17～79 years old)subjected from NHANESⅢ were enrolled and served as a training set to construct the new biological age(new Bioage)model.Multiple linear regression was used to construct models for new Bioage and age-adjusted biological age(new-agefixed Bioage),and other types of biological ages were calculated.Pearson correlation analysis was performed to assess the correlation between biological age and chronological age.Based on new-agefixed Bioage,biological age acceleration was calculated,and then according to the results,the participants were divided into accelerated biological aging group(biological age acceleration≥0,n=3 884)and decelerated biological aging group(biological age acceleration<0,n=4 350).Weighted data comparisons were conducted using the survey package in R,and Cox regression analysis was used to assess the impact of biological age acceleration on the mortality of the participants.Receiver operating characteristic(ROC)curve was plotted to determine the effect of new-agefixed Bioage and biological age acceleration on the area under the curve(AUC)for the mortality.Results The new-agefixed Bioage model,composed of 9 variables,had the highest AUC value(AUC=0.889 2,P<0.001)in predicting mortality outcomes and showed high correlation with chronological age and other biological ages.The decelerated biological aging group had significantly larger proportions of males,whites,education level of high school or higher,middle to high household income,married(or with a partner),engaging in physical activity,having private insurance,and cancer(P<0.05),lower BMI,slower biological age acceleration level,and less proportions of smokers,hypertension,diabetes,cardiovascular disease,and chronic obstructive pulmonary disease when compared with the accelerated biological aging group(P<0.05).Cox regression analysis indicated that,compared to the decelerated biological aging group,the accelerated biological aging group had a significantly increased risk of mortality in Model3[adjust for age group,gender,race,BMI,education level,household income,married(or with a partner),smoking status,heavy alcohol consumption,insurance status,physical activity,hypertension,diabetes,cardiovascular disease,chronic obstructive pulmonary disease,and cancer](HR=1.62,95%CI:1.28-2.06,P<0.001).ROC curve analysis revealed that new-agefixed Bioage significantly increased the AUC values(AUC=0.781,P<0.001;AUC=0.731,P<0.001)for middle-aged and elderly populations,while biological age acceleration significantly improved the AUC values(AUC=0.756,P<0.001)for the middle-aged population.Conclusion The new-agefixed Bioage model demonstrates high correlation with chronological age and other biological ages,and has good predictive performance for mortality outcomes,particularly in middle-aged and elderly populations.

ObjectiveThis study explores the methods of lung tissue extraction and fixation required for pathological studies of fetal rats, based on the unique physiological structure of fetal rat lung tissue and existing lung tissue fixation techniques for adult rats. MethodsSix pregnant adult SD rats at 20.5 days of gestation were subjected to cesarean section to obtain fetal rats. Four healthy fetal rats with similar body weight, vital signs, and respiratory status were selected from each pregnant rat, and they were randomly divided into the following groups using a random number table: direct lung infiltration group, lung infiltration group after intratracheal infusion, whole-body infiltration group of fetal rats, and whole-body infiltration group after intratracheal infusion of fetal rats. To systematically compare and analyze the anatomical morphology under different fixation methods, lung tissues from four groups of fetal rats were harvested, perfused, and fixed, and the gross morphology of lung tissues in each group was observed. Paraffin sections were prepared and stained with Hematoxylin-Eosin (H&E). The histological morphology of the whole lung, alveoli, and bronchi was further examined under optical microscopy. ResultsIn the direct lung infiltration group, the hilar structures were unclear, lung lobation was indistinct, the shape was irregular, lung cavities were small, and alveoli and bronchi were shrunken. In the lung infiltration group after intratracheal infusion, the hilar structures were clear, lobation was pronounced, the shape was regular, lung cavities were large, and alveoli and bronchi were full. Both the whole-body infiltration group and whole-body infiltration group after intratracheal infusion of fetal rats exhibited visible lungs, hearts, skins, and other organs. The lung tissues of both groups showed obvious lobulation, irregular shape, and damage at the margins of lung lobes. In the whole-body infiltration group, the thoracic cavities of the fetus were flattened, lung cavities were small, and alveoli and bronchi were shrunken. In the whole-body infiltration group after intratracheal infusion of fetal rats, the fetal thoracic cavities were full, lung cavities were large, and alveoli and bronchi were relatively full. ConclusionThe lung infiltration after intratracheal infusion method for fetal rat lung tissue fixation outperforms direct lung infiltration, whole-body infiltration of fetal rats, and whole-body infiltration after intratracheal infusion of fetal rats in terms of preservation of the lung tissue's original morphology, paraffin sectioning, staining, and pathological observation and analysis. The embedding, sectioning, and staining processes are also simple and save consumables. Therefore, intratracheal infusion followed by lung infiltration method is recommended for fixation in histopathological observation of fetal rat lung tissue.

Objective:To analyze the influencing factors for special interests in rheumatology diseases in residents after their completion of standardized residency training.Methods:A questionnaire survey was conducted among general practitioners who participated in residential training in the base from September 1, 2011 to June 30, 2024, and the possible influencing factors were collected and analyzed.Results:Eighty-six cases (63.2%) of general practitioners expressed interest in rheumatology. A higher proportion of physicians showed interest in rheumatology when they engaged in the following activities: taking rheumatology as a subspecialty in practice on rheumtic diseases [16.3% (14/86) vs. 0 (0/50), χ2=15.93, P<0.001], taking night shifts during rheumatology rotation [57.0%(49/86) vs. 20% (10/50), χ2=17.60, P<0.001], studying with mentors of rheumatogy[89.5%(77/86) vs. 54.0%(27/50), χ2=22.19, P<0.001], participating in research on rheamatic diseases[16.3% (14/86) vs. 2.0% (1/50), χ2=6.57, P=0.010], involved in rheumatology outpatient teaching sessions [33.7%(29/86) vs. 8.0% (4/50), χ2=11.38, P<0.001], and receiving career guidance on mentors of rheumatology[39.5%(34/86) vs. 18.0% (9/50), χ2=6.78, P=0.012]. Multivariate logistic analysis revealed that the following were independent promoting factors for developing interest in rheumatology: taking rheumatology as a subspecialty in practice [ OR(95% CI) =3.82 (1.5,9.7), P=0.005], taking night shifts during rheumatology rotation [ OR(95% CI) =3.41 (1.25,9.28), P=0.017], and studying with mentors of rheumatology[ OR(95% CI) =6.44 (2.18,19.08), P<0.001]. Conclusion:Most residents expressed interest in rheumatology. Taking rheumatology as a practice sub-specialty, taking night shifts and during rotation and learning from mentors have a positive impact on residents interest in rheumatology after their completion of residency.

Objective To investigate the effects of the long noncoding RNA(lncRNA),KCNQ1 overlapping transcript 1(KCNQ1OT1),on lipopolysaccharide(LPS)-induced proliferation and osteogenic differentiation of human periodontal ligament stem cells(hPDLSCs)by targeting miR-218.Methods HPDLSCs were cultured in vitro and randomly assigned into hPDLSC,LPS,pcDNA-KCNQ1OT1,pcDN A,miR-218,or miR-NC groups.Cell proliferation and alizarin red staining of the cells were observed.The activity of alkaline phos-phatase,the expression of KCNQ1OT1 and miR-218,the levels of interleukin-1 β(IL-1β),interleukin-6(IL-6),and tumor necrosis factorα(TNF-α),and the expression of osteopontin(OPN),osteocalcin(OCN),Runt-related transcription factor 2(RUNX2),and bone morpho-genetic protein 2(BMP2)in cells were detected.A dual luciferase assay was performed to verify the relationship between KCNQ1OT1 and miR-218.Results Compared with the hPDLSC group,the cell proliferation rate,the alkaline phosphatase activity,and the expression of KCNQ1OT1,OPN,OCN,RUNX2,and BMP2 were significantly decreased,while the expression of miR-218 and the levels of IL-1β,IL-6,and TNF-α were significantly increased in the LPS group(P＜0.05).Compared with the pcDNA-KCNQ1OT1 group,all the above indicators had the same trend in the miR-218 group(P＜0.05).Compared with the LPS group,the cell proliferation rate,the alkaline phos-phatase activity,and the expression of KCNQ1OT1,OPN,OCN,RUNX2,and BMP2 were significantly increased,while the expression of miR-218 and the levels of IL-1β,IL-6,and TNF-α were significantly decreased in the pcDNA-KCNQ1OT1 group(P＜0.05).There was a targeting relationship between KCNQ1OT1 and miR-218.The luciferase activity in the KCNQ1OT1-WT+miR-218 group was significantly lower than that in the KCNQ1OT1-WT+miR-NC group(P＜0.05).Conclusion KCNQ1OT1 can downregulate miR-218 and promote LPS-induced proliferation and osteogenic differentiation of hPDLSCs.

Dendrobium is the largest genus of the Orchidaceae family.The fresh and dried stems of many species of this genus have been used as Shihu(Dendrobii Caulis)in traditional Chinese medicine,it is known as the foremost of the"Nine Great Herbs of China".Ancient texts highlight its uses for"strengthening yin,enhancing essence,nourishing the five viscera,alleviating fatigue,and dispelling skin heat and prickly heat".Modern research confirms that the polysaccharides and alkaloids it contains have antiviral ef-fects,it can apply in treating immunodeficiency caused by viral infections clinically.While studies are gradually uncovering the antivi-ral mechanisms and material basis of Dendrobium,the lack of systematic analysis and organization has hindered its resource develop-ment.The paper employed CiteSpace software for bibliometric analysis of Chinese and English literature on Dendrobium.It reviewed the herbalism,material basis,and mechanisms of its antiviral properties building upon the systematic review of ancient materia medica and modern literature.Results indicate that Dendrobium can boost vital energy and resist pathogens,showing great potential in antiviral drug development.

Objective: To determine the clinical efficacy and mechanism of Piwei Peiyuan Pill (PPP) combined with moxibustion for treating patients with chronic atrophic gastritis (CAG) with spleen and stomach weakness syndrome. Methods: Ninety-six CAG patients with spleen and stomach weakness syndrome who met the inclusion and exclusion criteria were enrolled at the Department of Spleen and Stomach Diseases of the Second Affiliated Hospital of Anhui University of Chinese Medicine from June 2022 to December 2023. The patients were randomly divided into a control, a Chinese medicine, and a combined group using a random number table method, with 32 cases in each group (two cases per group were excluded). The control group was treated with rabeprazole combined with folic acid tablets (both thrice daily), the Chinese medicine group was treated with PPP (8 g, thrice daily), and the combined group was treated with moxa stick moxibustion (once daily) on the basis of the Chinese medicine group for 12 consecutive weeks. Gastric mucosa atrophy in the three groups was observed before and after treatment. The gastric mucosal pathological score was evaluated. The Patient Reported Outcome (PRO) scale was used to evaluate the patients′ physical and mental health status and quality of life.An enzyme-linked immunosorbent assay was used to detect serum tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-4, IL-10, IL-37, and transforming growth factor (TGF)-β levels in each group. Real-time fluorescence PCR was used to detect the relative expression levels of signal transducer and activator of transcription 3 (STAT3) and mammalian target of rapamycin (mTOR) mRNA in each group. Western blotting was used to detect the relative expression levels of proteins related to the STAT3/mTOR signaling pathway, and the adverse drug reactions and events were recorded and compared. Results: There was no statistical difference in age, gender, disease duration, family history of gastrointestinal tumors, alcohol consumption history, and body mass index among the three groups of patients.The total therapeutic efficacy rates of the control, Chinese medicine, and combined groups in treating gastric mucosal atrophy were 66.67% (20/30), 86.67% (26/30), and 90.00% (27/30), respectively (P<0.05). Compared to before treatment, the pathological and PRO scale scores of gastric mucosa in each group decreased after treatment, and TNF-α, IL-1β, IL-37, and TGF-β levels decreased. The relative STAT3 and mTOR mRNA expression levels, as well as the relative STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels decreased (P<0.05), whereas the IL-4 and IL-10 levels increased (P<0.05). After treatment, compared to the control group, the pathological score of gastric mucosa, PRO scale score, TNF-α, IL-1β, IL-37, TGF-β content, relative STAT3 and mTOR mRNA expression levels, and relative STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels in the Chinese medicine and combined groups after treatment were reduced (P<0.05), whereas the IL-4 and IL-10 levels increased (P<0.05). After treatment, compared to the Chinese medicine group, the combined group showed a decrease in relative STAT3, mTOR mRNA expression levels, and STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels (P<0.05). Conclusion The combination of PPP and moxibustion may regulate the inflammatory mechanism of the body by inhibiting the abnormal activation of the STAT3/mTOR signaling pathway, upregulating related anti-inflammatory factor levels, downregulating pro-inflammatory factor expression, and increasing related repair factor expression, thereby promoting the recovery of atrophic gastric mucosa, reducing discomfort symptoms, and improving the physical and mental state of CAG patients with spleen and stomach weakness syndrome.

[Objective] To investigate the factors associated with alanine aminotransferase (ALT) abnormalities in multi-ethnic blood donors across five Zang autonomous prefectures in the plateau regions of Qinghai Province, and to provide evidence for ensuring blood safety and formulating screening strategies. [Methods] A retrospective analysis was performed on the ALT abnormal test results of blood donors in the Zang autonomous prefectures of Qinghai from 2022 to 2024. The correlations between ALT levels and factors including gender, age, altitude, and infectious markers were investigated. [Results] The overall ALT unqualified rate among blood donors in this region was 9.01%. Significant differences in ALT levels were observed across genders and age groups (P<0.05). Variations in ALT abnormality rates were also noted among different plateau regions (P<0.05). Overall, ALT values exhibited an increasing trend with rising altitude. The average ALT unqualified rates were 11.19% in Zang donors, 7.96% in Han donors, and 4.79% in donors from other ethnic groups (P<0.05). No statistically significant association was observed between ALT abnormality and the presence of HBV/HCV infectious markers (P>0.05). [Conclusion] In the plateau areas of Qinghai, multi-ethnic blood donors have a relatively high ALT levels and ALT unqualified rates, showing distinct regional characteristics. ALT elevation in voluntary blood donors is related to non-pathological factors such as gender, age, and dietary habits, but not to infectious indicators.

Objective: To investigate the efficacy and incidence of adverse reactions of therapeutic erythrocytapheresis in high altitude polycythemia (HAPC) population. Methods: A retrospective study was conducted on 243 HAPC patients who were either native residents or long-term workers in Xizang and underwent therapeutic erythrocytapheresis in the Chengdu Office Hospital of the People's Government of Xizang Autonomous Region from 2021 to 2023. A comparative study was carried out on the changes in blood routine, vital signs, skin color, serum iron metabolism data, and the incidence of adverse reactions before and after the procedure. Results: After erythrocytapheresis, significant decreases were observed in red blood cell (RBC) count (7.06±0.89×10 vs 6.08±0.93×10 /L, P<0.001], hemoglobin (HGB, 211.59±17.99 vs 182.76±19.83 g/L, P<0.001), hematocrit (Hct) [(65.30±6.45)% vs (55.56±8.12)%, P<0.001], serum iron (14.46±4.38 vs 11.77±3.78 μmol/L, P=0.003), total iron-binding capacity (126.62±4.47 vs 123.73±3.77 μmol/L, P=0.002), transferrin (1.88±0.41 vs 1.77±0.12 g/L, P=0.023), transferrin saturation [(11.32±3.11)% vs (9.43±2.78)%, P=0.004], serum ferritin (832.4±295.6 vs 665.3±249.2 ng/mL, P<0.001), systolic blood pressure (123.86±14.43 vs 118.51±13.68 mmHg, P<0.001) and diastolic blood pressure (81.68±9.54 vs 74.28±7.61 mmHg, P<0.001). In contrast, platelet count (Plt, 137.21±46.21 ×10 vs 147.94±50.66 ×10 /L, P<0.001) and oxygen saturation [(93.97±3.29)% vs (95.84±2.27)%, P<0.001] increased. No significant differences were found in white blood cell (WBC) count [5.35 (4.59, 6.44)×10 /L vs 5.43 (4.54, 6.53) ×10 /L, P=0.690], unsaturated iron-binding capacity (112.15±0.50 vs 111.96±0.25 μmol/L, P=0.074) and pulse rate (73.42±11.28 vs 73.19±7.18 beats/min, P=0.750). Furthermore, skin color of the face (conjunctiva, lips) and palms mitigated after therapeutic erythrocytapheresis, changing from purplish-red to red. The total incidence of adverse reactions during erythrocytapheresis was 13.98% (34/243), including citrate toxicity 12.75% (31/243), puncture site hematoma 0.82% (2/243) and blood volume imbalance 0.41% (1/243). Conclusion: Therapeutic erythrocytapheresis could rapidly decrease HCT, Hb, serum iron, transferrin and transferrin saturation levels in HAPC patients, with a low incidence of adverse reactions. Therefore, therapeutic erythrocytapheresis has broad clinical application prospects in Xizang Autonomous Region.

Objective To evaluate the overall implementation of the WS 76-2020 standard in Anhui Province, China and identify and analyze the factors affecting the implementation of the standard, and to provide a basis for the effective implementation and revision of WS 76-2020. Methods According to the requirements of the Notice of the Department of Regulations in National Health Commission on the 2024 assessment of implementation of mandatory standards, an evaluation of radiological health standards was organized and conducted in Anhui Province. The evaluation involved the three dimensions of standard implementation status, technical content of the standards, and effectiveness of standard implementation, with subsequent data analysis. Results The total evaluation score for WS 76-2020 was 87.83 points, indicating that the standard effectively guided the quality control testing of medical X-ray diagnostic equipment. However, stability testing was either underutilized or not performed in practice. The qualified rate of X-ray diagnostic equipment in the province was 94.26%, with equipment performance issues identified as the leading contributor to non-qualified instances. Expert discussions highlighted recommendations particularly concerning the operability, applicability, and scientific rigor of the standard. Conclusion It is recommended to strengthen the dissemination and training for the standard, promote medical institutions to voluntarily conduct stability testing, provide supplementary clarifications or revisions for problematic clauses, and standardize quality control testing techniques for radiological diagnostic equipment.
