Objective: To analyze the current burden of autism spectrum disorder (ASD) among children and adolescents in China and globally, and to predict the disease burden from 2024 to 2035, providing a scientific basis for formulating relevant public health policies and intervention measures. Methods: Based on the Global Burden of Disease (GBD) database in 2023, the Joinpoint regression model was used to analyze the changing trends of the disease burden of ASD among children and adolescents in China and globally from 1990 to 2023, and the average annual percent change (AAPC) was calculated. An autoregressive integrated moving average (ARIMA) model was constructed to predict the disease burden trends of ASD among children and adolescents in China and globally from 2024 to 2035. Results: The prevalence and disability adjusted life years (DALYs) rate of ASD among children and adolescents in China increased from 452.69/100 000 and 86.67/100 000 in 1990 to 762.84/100 000 and 148.52/ 100 000 in 2023(AAPC=1.60%, 1.65%, both P <0.01). The prevalence and DALYs rate of ASD among children and adolescents globally increased from 648.49/100 000 and 123.47/100 000 to 862.44/100 000 and 167.16/100 000(AAPC=0.87%, 0.93%, both P <0.01). In 2023, the highest ASD prevalence and DALY rates occurred in children under 5 years old, with China reporting 848.14/100 000 and 166.69/100 000, both below the global averages of 928.80/100 000 and 181.34/100 000. Projections indicated that by 2035, the ASD prevalence and DALY rates in China would rise to 906.83/100 000 and 168.71/100 000, still below the global averages of 938.04/100 000 and 184.49/100 000. Conclusion The disease burden of ASD among children and adolescents in China and globally has generally increased from 1990 to 2023, with a higher risk of disease at younger ages.

Spastic lower limb paralysis is a common complication following central nervous system injury, including stroke, cerebral palsy, and brain or spinal cord trauma, with high incidence and complex conditions. In recent years, minimally invasive treatment techniques have rapidly advanced, offering new avenues to improve motor function and quality of life for these patients. However, clinical decision-making involves multidisciplinary input, such as rehabilitation, neurosurgery, orthopedics, and standardized treatment guidelines are lacking. This review systematically summarizes commonly used minimally invasive treatments for spastic lower limb paralysis, including their mechanisms, indications, efficacy, and limitations, and compares findings from domestic and international studies. The aim is to provide guidance for clinical decision-making, optimize treatment strategies, and promote development of individualized therapies.

Objective To analyze the screening results of prostate cancer(PCa)based on the serum prostate-specific antigen(PSA)level in middle-aged and elderly men in Kaifeng,so as to provide reference for optimizing the early screening strategy of PCa.Methods A multicenter cross-sectional design was adopted to analyze the serum PSA test results of male residents aged 52 to 94 collected from 14 community health service stations in Kaifeng during Jul.2024 and Apr.2025. Participants with PSA ≥4 μg/L were recommended to undergo prostate biopsy at a tertiary grade A hospital for a confirmed diagnosis.Multivariate logistic regression was used to analyze the influencing factors of referral compliance.The PSA positivity rate,referral loss rate,puncture willingness rate,and biopsy positivity rate were calculated.Results A total of 2812 men received free PSA screening.Among them,248 had abnormal PSA(≥4 μg/L),with a positive rate of 8.8%(248/2812).Only 105 cases were successfully referred to a tertiary grade A hospital,with a referral rate of 42.3%(105/248),and the referral loss rate reached 57.7%.Fifty-seven patients were advised to undergo prostate biopsy,but only 23 actually underwent prostate biopsy,and the willingness rate was 40.4%(23/57).Fourteen cases were diagnosed with PCa and the positive rate of prostate biopsy was 60.9%(14/23).The overall detection rate of PCa was 0.5%(14/2812).In the screening stage,the median PSA was 6.7(4.8-11.2)μg/L.The Spearman correlation analysis showed a positive correlation between participant age and PSA level(r_s=0.28,P＜0.001).In the diagnostic stage,only 40.4% of the referred patients underwent prostate biopsy,and the loss rate reached 59.6%.The median PSA in the PCa group was significantly higher than that in the non-PCa group(9.8 μg/L vs. 5.1 μg/L,P=0.002).Multivariate logistic regression analyses showed that advanced age(OR=1.08)and educational level of primary school or below(OR=3.32)were independent influencing factors for referral disorders(P＜0.001).In terms of screening efficacy,the overall biopsy positivity rate was 5.6%(14/248).Conclusion Conducting PCa screening based on PSA testing among middle-aged and elderly male residents can significantly increase the detection rate of clinically meaningful PCa,thereby improving the overall prognosis of patients.However,insufficient referral compliance(only 42.3%)and low puncture willingness rate(only 40.4%)have limited the screening benefits.Therefore,the research suggests that measures such as strengthening health education,popularizing relevant knowledge,and providing referral support are needed to reduce the churn rate.

ObjectiveTo systematically evaluate the efficacy and safety of Qi-reinforcing and blood-activating/stasis-expelling Chinese patent medicines in the treatment of coronary microvascular disease （CMD）. MethodsPubMed， Cochrane Library， CNKI， Wanfang Data， and VIP were searched for the randomized controlled trials （RCTs） on the treatment of CMD with Chinese patent medicines for reinforcing Qi and activating blood/expelling stasis with the time interval from inception to December 31， 2023. The primary outcome indicators included the index of microcirculatory resistance （IMR）， coronary flow reserve （CFR）， and corrected TIMI flow frame count （cTFC）. The secondary outcome indicators included symptomatic efficacy， left ventricular ejection fraction （LVEF）， hypersensitive C-reactive protein （hs-CRP）， nitric oxide （NO）， and adverse events. Cochrane risk-of-bias assessment tool 2.0 （RoB 2.0） and Stata 17.0 were used for literature quality evaluation and meta-analysis of the included RCTs. The Grading of Recommendations， Assessment， Development and Evaluation （GRADE） was used to evaluate the quality of evidence. ResultsA total of 36 RCTs were included in this study， involving 3 029 patients. Compared with conventional Western medicine alone， the combined use of Chinese patent medicines for reinforcing Qi and activating blood/expelling stasis and Western medicine reduced the IMR ［mean difference （MD）=-5.93， 95% confidence interval （95%CI） ［-8.73，-3.14］， n=382， P<0.01］， cTFC （MD=-9.35， 95%CI ［-13.94，-4.76］， n=618， P<0.01）， and hs-CRP ［standard mean difference （SMD）=-1.50， 95%CI ［-1.90，-1.11］， n=1 483， P<0.01］， improved the CFR （SMD=1.14， 95%CI ［0.08，2.19］， n=304， P=0.03）， symptomatic efficacy ［relative risk （RR）=1.36， 95%CI ［1.21，1.53］， n=756， P<0.01］， LVEF （MD=4.39， 95%CI ［2.31，6.47］， n=533， P<0.01）， and NO （SMD=3.16， 95%CI ［2.07，4.25］， n=946， P<0.01） of CMD patients. In terms of safety， the combined therapy reduced the occurrence of adverse events in CMD patients （RR=0.49， 95%CI ［0.29，0.82］， n=591， P=0.01）. GRADE showed moderate quality evidence for adverse events， low quality evidence for cTFC， symptomatic efficacy， LVEF， and NO， and very low quality evidence for IMR， CFR， and hs-CRP. ConclusionBased on microcirculatory function indicators， the combined use of Qi-reinforcing and blood-activating/stasis-expelling Chinese patent medicines and Western medicine may further improve the coronary microvascular function in CMD patients with good safety. The above conclusions remain to be verified with high-quality clinical trials.

ObjectiveTo investigate the current status of emergency management for severe mental disorders in Shanghai, and to provide countermeasures and suggestions for the establishment of a sound emergency management system for severe mental disorders and the enhancement of emergency management capability. MethodsA questionnaire survey and qualitative interviews were used to conduct an investigation into the emergency management in 17 district-level mental illness prevention and control institutions in Shanghai, which includes the basic situation of emergency management for severe mental disorders, the construction of emergency response teams and personnel, emergency preparedness drills and training, emergency management plans and rules and regulations, and problems encountered in emergency management. ResultsIn terms of emergency management mechanism and basic situation, resources such as personnel allocation, security funds and green channel were well equipped in each district-level mental illness prevention and control institution in Shanghai. However, the equipment of some hardware facilities was still insufficient to some extent. Therefore, further improvement on the emergency management mechanism for severe mental disorders was needed. With regard to the construction of emergency team and personnel allocation, the majority were those aged between 35‒<45 years old, with a bachelor’s degree, and more than 10 years of working experience. For example, 90.27% staff in district-level mental illness prevention and control institution had a bachelor’s degree or above, which was higher than that among the staff in community-level (73.60%); staff majored in clinical medicine in district-level institution accounted for the proportion at 52.71%, higher than that among the staff in community-level (28.86%); 57.24% staff in district-level institution had an intermediate professional title, higher than that among the staff in community-level (42.28%); and 69.90% staff in district-level institution had more than 10 years of working experience, higher than that among the staff in community-level (43.62%). In the aspect of emergency drills and training, all district-level mental illness prevention and control institutions in Shanghai had a high demand for emergency training, and the weak aspects mainly focused on lack of emergency service protocols, skills of addressing technical challenges, and construction of effectiveness evaluation system. Moreover, the teaching methods were primarily centered on case analysis, simulation drills, interactive discussions, and so forth. Concerning emergency management plans and rules and regulations, all districts in Shanghai had relatively established well-developed systems for emergency response plans, emergency response leadership groups, and emergency response operational task forces for severe mental disorders. About half of the institutions had established other rules and regulations related to emergency management of severe mental disorders in addition to emergency plans. ConclusionShanghai has initially established an emergency management system for severe mental disorders, but it is still fragile in specialized training for emergency management of severe mental disorders, construction of emergency management mechanisms, and the building-up of grassroots emergency teams. Further priorities should include strengthening emergency management training, enhancing the construction of emergency management personnel teams, and gradually establishing a more comprehensive and integrated emergency management mechanism for severe mental disorders.

AIM:To investigate the effect of intrinsic specific transforming growth factor-β(TGF-β)signaling on regeneration and repair of myofibers in acute skeletal myositismice model induced by cardiotoxin(CTX).METHODS:One hundred and eighty-six wild C57BL/6 mice and one hundred and thirty-eight mice with conditional knockout of TGF-β receptor 2(TGF-βr2)in myofibers(SM TGF-βr2-/-mice)were selected.CTX injection to anterior tibial muscle(TA)in-duced acute myoinjury in mice.Some SM TGF-βr2-/-mice were given Smad signaling agonist SRI-011381(SRI)intramus-cular injection.All mice were mainly divided into the following groups:control group,SM TGF-βr2-/-group and SM TGF-βr2-/-+SRI group.Twenty-four mice were selected in each group.RT-qPCR and immunofluorescence staining were used to detect the relative mRNA level,protein expression of inflammatory cytokines and low-density lipoprotein receptor-related protein 1(LRP1),respectively,while the relative protein expression of myosin heavy chain 3(MHY3)and embryonic myosine heavy chain(eMHC)in damaged muscle was detected by Western blot and immunofluorescence staining.In vi-tro,after being extracted from neonatal mice,myogenic precursor cells(MPCs)were cultured in an pro-inflammatory mi-lieu and treated with SRI,recombinant mouse extracellular matrix protein 1(rmECM1)alone or in combination.Hereby,they were divided into the following seven groups:control-MPCs group,control-MPCs+LPS group,TGF-βr2-/--MPCs group,TGF-βr2-/--MPCs+LPS group,TGF-βr2-/--MPCs+LPS+SRI group,TGF-βr2-/--MPCs+LPS+rmECM1 group,and TGF-βr2-/--MPCs+LPS+SRI+rmECM1 group.Six mice were selected in each group.RT-qPCR and Western blot were used to detect the relative mRNA level,protein expression of major histocompatibility complex class I molecules(MHC-I/H-2Kb),major histocompatibility complex class II molecules(MHC-II/H2-Eα),Toll-like receptor 3(TLR3),and LRP1.And the relative protein expression of MoyD and myogenin in myotubes was detected by immunofluorescence staining.RE-SULTS:In vivo,compared with control group,SM TGF-βr2-/-group showed the significant upregulation of pro-inflamma-tory cytokines(P<0.05),and the opposite trend of anti-inflammatory cytokines,LRP1,MHY3,eMHC in the injured muscle(P<0.05),with delayed regeneration and repair of myofibers.In vitro,compared with control-MPCs+LPS group,LRP1,MoyD and myogenin significantly downregulated in TGF-βr2-/--MPCs+LPS group,but the downregulation trend was corrected after giving SRI treatment(P<0.05).In addition,compared with the TGF-βr2-/--MPCs+LPS group,the combi-nation of rmECM1 and SRI significantly upregulated the protein expression of MyoD and myogenin(P<0.05).CONCLU-SION:In a mouse model of acute skeletal myositis,intrinsic TGF-β signaling specifically in myofibers regulates local im-mune behavior.It promotes the expression of LRP1 in damaged muscle via Smad2/3 signaling,and LRP1 can then fully bind to ECM1,thereby facilitating muscle regeneration and repair,and improving the prognosis of acute skeletal myositis.

Objective:Using ecological niche width and situation model,the operation and management of public Traditional Chinese Medicine(TCM)hospitals in 16 cities in Shandong Province were evaluated to put forward countermeasures.Methods:The relevant index data of public TCM hospitals in 16 cities in Shandong Province from 2019 to 2022 were collected to analyze the development status.The ecological niche width model and niche situation model were applied to evaluate the operation and management of public TCM hospitals in 16 cities in Shandong.Results:The top three public TCM hospitals in terms of average ecological niche width were City G,City P and City F.The ecological niche situation value of public TCM hospitals in City K,City A and City J ranked the top three.Conclusion:The dimensions of operation management structure of public TCM hospitals in Shandong need to be enhanced and the development of operation management space needs to be balanced.It is feasible to evaluate operation management by using ecological niche width and situation model.It is suggested to improve the allocation efficiency of health personnel,facilities,funds and other resources;promote the spatial balanced development of operation management;promote the application of ecological niche width and situation model in the field of medicine and health management.

Objectives:QT interval prolongation during treadmill test exercise is one of the clinical feature of patients with long QT syndrome(LQTS).This study aimed to explore the feasibility and efficacy of treadmill exercise testing as an auxiliary diagnosis tool for LQTS in clinical practice.Methods:We enrolled normal healthy individuals,common cardiovascular disease patients,and clinically diagnosed or suspected LQTS patients,who underwent treadmill exercise test from July 2023 to July 2024 at Fuwai Hospital.A special treadmill exercise testing procedure was designed to record the QT interval correction(QTc)intervals of the twelve lead electrocardiogram at 6 time points when performing the exercise tablet,including supine,sitting,standing,peak exercise,and recovery at 1-minute and 4-minute.The differences in QTc intervals among healthy group,cardiovascular diseases group,and suspected LQTS group were compared.Results:A total of 80 cases were consecutively enrolled,including 37 normal healthy controls,25 patients with common cardiovascular disease,and 18 patients with suspected LQTS.The QTc intervals at 6 points did not differ significantly between normal healthy controls and patients with cardiovascular disease,with QTc intervals less than 480 ms at all measurement.For patients with suspected LQTS,67.7%(12/18)of these patients presented a QTc interval≥480 ms at the 4-minute during recovery period.Among them,5 cases were confirmed to have pathogenic gene mutations of LQTS by genetic testing(including 1 case with a lying electrocardiogram QTc interval of 489 ms diagnosed with LQTS 1 type and a QTc interval of 636 ms during the 4-minute recovery period after exercise);5 clinically diagnosed patients(negative or undetectable in genetic testing)with a Schwartz score≥4,and the remaining 2 patients had a Schwartz score of 3.The remaining 5/18 patients,include 2 patients with clinical Schwartz scores≥4 and 3 patients with clinical suspicion(Schwartz scores 2-3)had a 4 min QTc interval of 445-480 ms during exercise recovery.Another patient with clinical suspicion(Schwartz score 3)had a 4 min QTc interval of<445 ms during exercise recovery and a negative genetic test at a later stage.Receiver operating characteristic curve analysis showed a sensitivity of 83.3%and specificity of 98.4%for QTc interval≥482 ms during the 4-minute recovery period of exercise as the LQTS diagnostic cutoff.Conclusions:This study results suggest that this special treadmill exercise testing protocol is effective in identifying LQTS and has strong feasibility and generalizability for clinical practice.

Objective To explore the effects of sialic acid intervention during pregnancy and the lactational period on the intestinal function of autism model rats.Methods Thirty SPF-grade adult male and female Wistar rats were mated.The successfully pregnant rats were randomly assigned to a valproate-induced model(VPA)group,a high-dose sialic acid(SAH)group,a medium-dose sialic acid(SAM)group,a low-dose sialic acid(SAL)group,and a control(CON)group(n=6 per group)and were housed individually in single cages.On the 12.5th day of pregnancy(E12.5),rats in the VPA and SA intervention groups were given a single intraperitoneal injection of 600 mg/kg sodium valproate(VPA),while the pregnant rats in the CON group were given an equal amount of normal saline.The SA intervention period was from E12.5 to the 21st day after parturition.Feces of offspring rats in each group were collected.The diversity and structure of the gut microbiota were detected by 16S rRNA sequencing.The intestinal transit speed in each group was detected by intragastric administration of carmine.The levels of intestinal-related neurotransmitters(substance P,enkephalin,5-hydroxytryptamine,vasoactive intestinal peptide,and glutamate,gamma-aminobutyric acid)in the blood of rats in each group were detected by ELISA.Results High-dose SA intervention did not affect the diversity of the gut microbiota in the VPA-induced autism model rats,but it changed the structure of the gut microbiota and increased the abundance levels of Prevotella_NK3B31 group,Prevotella,Prevotella spp.,Alloprevotella,Lachnospira,Ruminococcus,and Bacteroides(P＜0.05).High-dose SA also promoted the intestinal transit speed,and increased the levels of vasoactive intestinal peptide,5-hydroxytryptamine,and gamma-aminobutyric acid in serum.Conclusions SA intervention during pregnancy and the lactational period affects the intestinal transit speed of VPA-induced autism model rats,changes the structure of the gut microbiome,and increases the levels of vasoactive intestinal peptide,5-hydroxytryptamine,and gamma-aminobutyric acid.

Objective To explore the feasibility of using the left inferior phrenic vein as an anatomical landmark and prioritizing the dissection of the central adrenal vein in retroperitoneal laparoscopic left adrenalectomy(RLLA).Methods 116 patients who had RLLA carried out in our hospital between January 2021 and December 2023 were chosen.They were separated into the experimental group(RLLA with the left inferior phrenic vein as an anatomical landmark and prioritizing the dissection of the central adrenal vein)and the control group[conventional three-layer method anatomic retroperitoneal laparoscopic adrenalectomy(RLA)],with 58 cases in each group.The clinical data of the two groups were compared,and the intraoperative and postoperative 24 h clinical indicators,stress indicators,immune function,and complications were evaluated.Results RLLA was successfully completed in two groups,and no cases were converted to open surgery.The operation time,time for searching the central vein,retention time of the drainage tube and postoperative hospital stay in the experimental group were significantly shorter than those in the control group.The intraoperative blood loss and postoperative drainage volume were significantly less than those in the control group,the differences were all statistically significant(P<0.05);There was no statistically significant difference in the recovery time of gastrointestinal function between the two groups of patients after surgery(P>0.05).There were no statistically significant differences in preoperative inflammatory factors,stress indicators and immune function indicators between the two groups of patients(P>0.05).The white blood cell(WBC),C-reaction protein(CRP)and interleukin-6(IL-6)of the two groups of patients 24 hours after the operation were significantly higher than those before the operation,but the experimental group was significantly lower than the control group,the differences were statistically significant(P<0.05).The malondialdehyde(MDA)of the two groups of patients 24 hours after the operation was significantly higher than that before the operation,while the superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)were significantly lower than those before the operation,and the MDA in the experimental group was significantly lower than that in the control group,and the SOD and GSH-Px were significantly higher than those in the control group(P<0.05).The levels of CD4+and CD4+/CD8+in experimental groups of patients 24 hours after the operation were significantly decreased than those before the operation,and the levels of CD3+,CD4+and CD4+/CD8+in the experimental group were significantly higher than those in the control group.The differences were statistically significant(P<0.05).There was no statistically significant difference in CD8+between the two groups of patients 24 hours after surgery(P>0.05).The number of cases with intraoperative blood pressure fluctuations in the experimental group was significantly lower than that in the control group,the difference was statistically significant(P<0.05).Neither peritoneal injury,renal pedicle vascular injury or retroperitoneal hematoma occurred during or after the operation in the two groups of patients.Conclusion In RLLA,using the left inferior phrenic vein as an anatomical landmark and prioritizing the dissection of the central adrenal vein is feasible,which can improve surgical indicators,reduce stress response and immune response,and have clinical application value.
