Objective: To systematically evaluate the influencing factors for autism spectrum disorder (ASD) in Chinese children, so as to provide the evidence for risk prediction and intervention of ASD. Methods: The publications pertaining to the influencing factors for ASD in Chinese children were retrieved from CNKI, Wanfang Data, VIP, PubMed and Embase database from inception to August 2024. A meta-analysis was performed using R package version 4.4.1. Sensitivity analysis was performed using the "leave-one-out" evaluation procedure. Publication bias was assessed using Egger regression test. Results: A total of 38 high-quality articles out of 9 015 articles were finally included, covering 149 607 individuals, with 5 974 cases of ASD. The meta-analysis showed that demographic factors including family history of related diseases (OR=14.958), maternal age of ≥35 years (OR=2.287) and parental history of hazardous occupations (OR=3.511); pregnancy-related factors including history of abortion (OR=5.832), no folate supplementation before and during pregnancy (OR=4.566), tobacco exposure before and during pregnancy (OR=2.596), history of other adverse exposures before and during pregnancy (OR=3.533), history of infectious diseases during pregnancy (OR=3.753), history of non-infectious diseases during pregnancy (OR=2.563), psychological problems during pregnancy (OR=3.864), history of medication during pregnancy (OR=6.651), adverse environmental exposures during pregnancy (OR=3.754), severe pregnancy reactions (OR=5.082), abnormal perinatal period (OR=2.987), cesarean delivery (OR=1.659), other perinatal adverse factors (OR=3.856), history of neonatal asphyxia (OR=2.792) and neonatal jaundice (OR=3.687); parenting factors including non-exclusive breastfeeding (OR=2.510), early/excessive screen exposure (OR=3.589) and feeding problems (OR=3.113); and individual factors including being male (OR=3.333) and history of convulsions/epilepsy (OR=7.035) were influencing factors for ASD in Chinese children. Conclusions The prevalence of ASD in Chinese children is primarily associated with 23 influencing factors, including family history of related diseases, history of abortion, no folate supplementation before and during pregnancy, medication during pregnancy, early/excessive screen exposure and history of convulsions/epilepsy.

From the perspective of dynamic and static concept in traditional Chinese medicine， we explored the pathogenesis and treatment of attention deficit hyperactivity disorder （ADHD）. ADHD is categorized into "dynamic type" and "static type" based on symptom presentation. It is believed that the core disease mechanism of static type ADHD refers to insufficiency of essence and blood， as well as the loss of nourishment of brain marrow and heart blood； the dominant mechanism of dynamic type ADHD refers to excessive use of the mind and improper diet lead to the excessive movement of dragon-thunder fire （symbolizing hyperactivity）. The treatment should first differentiate between static type and dynamic type. The treatment for static type focuses on the spleen and kidney， and involves replenishing the acquired constitution to nourish the congenital， supporting the heart and spirit， and enriching the brain and marrow， so as to ensure sufficient qi and blood， abundant essence and strong spirit， thereby improving symptoms of attention deficits. The dynamic type should be treated by static method， and involves using calming medicinals to supplement， transform， and subdue to reach the aims of enriching yin and subduing yang， warming and supplementing the spleen and kidney， which helps restore the dragon-thunder fire to its balance. Based on the physiological characteristics of children， a dynamic-static differentiation and treatment system is established to provide a reference for the clinical treatment of ADHD.

Many ancient physicians emphasized the shared origins of traditional Chinese medicine (TCM) and the Book of Changes, which are both deeply rooted in yin and yang transformations. While the Book of Changes explores alterations in yin and yang, TCM focuses on their manifestations in the human body. Based on these shared origins, this paper examines attention deficit hyperactivity disorder (ADHD) treatment in children through the perspectives of TCM, the Book of Changes, and the Kan-Li. This study integrates children′s unique physiological characteristics and emphasizes the pivotal role of the four zang viscera: the heart, kidney, spleen, and liver. In TCM, the kidney governs water metabolism and shares an intricate, interdependent relationship with the heart. Understanding the kidney′s functions and clinical implications necessitates accounting for its connection with the heart. Similarly, therapeutic interventions that nourish the kidney inherently involve heart regulation, reflecting the principle of the mutual rooting of water and fire through the interplay of Kan (water) and Li (fire). This fundamental view of TCM resonates with the natural laws of the universe and the interplay between Heaven and Earth. The heart occupies the upper position, whereas the kidney resides below. Kidney yin ascends to nourish the heart, whereas heart fire descends to warm the kidney, embodying a vital heart-kidney interaction essential for sustaining life. Based on the physiological characteristics of children, the heart qi tends to be hyperactive, kidney qi and spleen qi are frequently insufficient, and liver qi often displays hyperactivity. This study suggests that the pathogenesis of ADHD involves kidney essence insufficiency and spleen yang deficiency. Furthermore, the homogeny of the liver and kidney implies that kidney deficiency can result in upper hyperactivity of liver yang, leading to yin-yang disharmony. Treatment for ADHD in children should focus on invigorating the spleen and kidney, as well as tonifying and replenishing the liver and kidney, to reestablish Kan-Li equilibrium. This approach addresses the underlying pathophysiology, alleviates ADHD symptoms, and facilitates recovery. Ultimately, it promotes a return to the child′s innate state of balance and vitality.

Background: The genetic basis for hyperglycaemia in pregnancy remain unclear. This study aimed to uncover the genetic determinants of gestational diabetes mellitus (GDM) and investigate their applications. Methods: We performed a meta-analysis of genome-wide association studies (GWAS) for GDM in Chinese women (464 cases and 1,217 controls), followed by de novo replications in an independent Chinese cohort (564 cases and 572 controls) and in silico replication in European (12,332 cases and 131,109 controls) and multi-ethnic populations (5,485 cases and 347,856 controls). A polygenic risk score (PRS) was derived based on the identified variants. Results: Using the genome-wide scan and candidate gene approaches, we identified four susceptibility loci for GDM. These included three previously reported loci for GDM and type 2 diabetes mellitus (T2DM) at MTNR1B (rs7945617, odds ratio [OR], 1.64; 95% confidence interval [CI],1.38 to 1.96]), CDKAL1 (rs7754840, OR, 1.33; 95% CI, 1.13 to 1.58), and INS-IGF2-KCNQ1 (rs2237897, OR, 1.48; 95% CI, 1.23 to 1.79), as well as a novel genome-wide significant locus near TBR1-SLC4A10 (rs117781972, OR, 2.05; 95% CI, 1.61 to 2.62; Pmeta=7.6×10-9), which has not been previously reported in GWAS for T2DM or glycaemic traits. Moreover, we found that women with a high PRS (top quintile) had over threefold (95% CI, 2.30 to 4.09; Pmeta=3.1×10-14) and 71% (95% CI, 1.08 to 2.71; P=0.0220) higher risk for GDM and abnormal glucose tolerance post-pregnancy, respectively, compared to other individuals. Conclusion Our results indicate that the genetic architecture of glucose metabolism exhibits both similarities and differences between the pregnant and non-pregnant states. Integrating genetic information can facilitate identification of pregnant women at a higher risk of developing GDM or later diabetes.

ObjectiveTo construct a rat model of psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type）， and evaluate the macroscopic manifestations and microscopic indicators of the model. MethodsTwenty-two SD rats were divided into normal group （n=3）， common psoriasis group （n=5）， spleen deficiency and dampness obstruction syndrome （external dampness type） group （n=7）， and psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group （n=7）. The spleen deficiency and dampness obstruction syndrome （external dampness type） rat model was established through 32-week exposure to an artificially simulated high-humidity environment， while the common psoriasis model was developed via 7-day topical application of imiquimod cream， and these two approaches were combined to construct a composite model of psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type）. Rats in the normal group were housed under normal humidity conditions. The general state， tongue manifestation of rats were observed to evaluate the macroscopic syndrome manifestations； the microscopic syndrome manifestations of rats were evaluated through adipose tissue and liver tissue changes； the severity of psoriasis in rats was evaluated through skin pathological changes， psoriasis area and severity index （PASI）， proliferating cell nuclear antigen （PCNA） expression and spleen tissue changes； changes in rat CD4⁺ interferon-γ⁺ cells （CD4⁺IFN-γ⁺ cells）， CD4⁺ tumour necrosis factor-α+ cells （CD4⁺ TNF-α⁺ cells）， and forkhead framing protein P3⁺ regulatory T cells （CD3⁺CD4⁺FoxP3⁺ Treg cells） were detected by flow cytometry. ResultsMacroscopically， both the spleen deficiency and dampness obstruction syndrome （external dampness type） group and psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group exhibited manifestations of spleen deficiency and dampness obstruction， including lethargy， huddling behavior， dull and disheveled fur， as well as soft or loose stools and perianal soiling in some individuals； both these two groups displayed enlarged tongue， swollen， and moist tongue texture， accompanied by slippery tongue surface. Microscopically， compared to the common psoriasis group， the psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group showed increased epididymal fat index （P＜0.05）； compared to the normal group and spleen deficiency and dampness obstruction syndrome （external dampness type） group， the psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group demonstrated significantly elevated spleen mass （P＜0.05）， while hepatic gross morphology and HE staining revealed no significant histopathological changes across all groups. Dorsal skin lesions were markedly exacerbated in the psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group when compared to those in common psoriasis group. Both the common psoriasis group and psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group exhibited significantly higher erythema scores， scaling scores， infiltration scores， PASI total scores， and proportions of CD3⁺CD4⁺FoxP3⁺Treg cells compared to the normal group and spleen deficiency and dampness obstruction syndrome （external dampness type） group （P＜0.05）， with pronounced PCNA-positive expression observed in the epidermal basal layer and dermis； the psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group displayed significantly increased proportions of CD4⁺TNF-α⁺cells compared to the spleen deficiency and dampness obstruction syndrome （external dampness type） group （P＜0.05）； whereas no significant differences were detected in CD4⁺IFN-γ⁺cell proportions among groups （P＞0.05）. ConclusionThe rat model of psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） can be successfully constructed by artificially simulating a high-humidity environment combined with imiquimod induction.

ObjectiveTo analyze the epidemiological characteristics of long COVID and to investigate its main influencing factors by examining individuals infected with SARS-CoV-2 between March and June 2022 in two communities in Shanghai, to lay the foundation for further research on the mechanism and clinical treatment of long COVID, and to provide the basis for the development of inexpensive, convenient, and feasible prevention and intervention strategies. MethodsA cross-sectional study was conducted, enrolling 6 410 individuals infected with SARS-CoV-2. Data were collected through a questionnaire survey. The incidence and common symptoms of long COVID were analyzed, along with their associations with demographic characteristics, medical history, and behavioral factors. A logistic regression model was used to identify the major factors associated with the development of long COVID symptoms. ResultsThe overall incidence rate of long COVID among the study population was 13.9%. The most commonly reported symptoms included fatigue (65.1%), attention disorders (23.1%), and cough (16.9%). The analysis showed that having underlying chronic diseases (OR=2.580, 95%CI: 2.165‒3.074), a history of allergies (OR=1.418, 95%CI: 1.003‒1.971), current smoking (OR=1.461, 95%CI: 1.013‒2.079), ever smoking (OR=2.462, 95%CI: 1.687‒3.551), a greater number of symptoms during the acute phase [1 symptom (OR=1.778, 95%CI: 1.459‒2.162), 2 symptoms (OR=2.749, 95%CI: 2.209‒3.409), ≥3 symptoms (OR=7.792, 95%CI: 6.333‒9.593)] and aggravated symptoms during the acute phase (OR=1.082, 95%CI: 1.070‒1.094) were factors associated with a higher risk of developing long COVID symptoms. Additionally, individuals who had consumed alcohol in the past year (OR=1.914, 95%CI: 1.344‒2.684) were more prone to objective long COVID symptoms. Among individuals under 50 years of age, females (OR=1.427, 95%CI: 1.052‒1.943) were more likely to develop objective long COVID symptoms. ConclusionThis study has identified the diversity of long COVID symptoms, which involve multiple organs and systems, including fatigue, attention disorders, cough, and joint pain. It has also revealed associations between long COVID and various demographic factors (e.g., age, gender), personal medical history (e.g., underlying chronic diseases, history of allergies), acute-phase characteristics (e.g., number and severity of symptoms), and behavioral factors (e.g., smoking, alcohol consumption). These findings highlight the need for further research and ongoing surveillance of long COVID and may inform the development of more targeted health management strategies for specific populations.

Based on WANG Xugao's “thirty methods of treating the liver”， it is believed that the occurrence and development of childhood tic disorders follow the dynamic progression from liver qi disease to liver fire disease and then liver wind disease. The basic pathogenesis of three stages are characterized by binding constraint of liver qi， liver fire hyperactivity， and internal stirring of liver wind. Moreover， liver-blood deficiency and stagnation， and malnutrition of liver yin as the main point in terms of the imbalance of liver qi， blood， yin， and yang should be considered， as well as the imbalance relationship of the five zang organs such as the involvement of other organs and the gradually reach of the other organs. Guided by the principles of “thirty methods of treating the liver”， the treatment of tic disorders in liver qi stage should focus on soothing the liver and rectifying qi， soothing the liver and unblocking the collaterals， using Xiaochaihu Decoction （小柴胡汤） and Sini Powder （四逆散）. The treatment of tic disorders in liver fire stage involves clearing， draining and resolving liver heat， using Longdan Xiegan Decoction （龙胆泻肝汤）， Xieqing Pill （泻青丸）， Danggui Longhui Pill （当归龙荟丸）， and Huagan Decoction （化肝煎）. The treatment of tic disorders in liver wind stage involves extinguishing wind and subduing yang， using Lingjiao Gouteng Decoction （羚角钩藤汤） and Liuwei Dihuang Pill （六味地黄丸）. Throughout the treatment process， attention should be paid to harmonizing the liver's qi， blood， yin， and yang， as well as addressing the pathology of other organs.
