Attention deficit hyperactivity disorder （ADHD） is often accompanied by tic disorder. The core pathogenesis is considered to be ministerial fire scorching yin and internal stirring of deficient wind， which leads to disharmony between the body and spirit， resulting in clinical manifestations. The treatment principles emphasize nourishing yin fluids， calming ministerial fire， and extinguishing endogenous wind （内风）. The method of nourishing yin fluids is applied throughout the entire treatment process， commonly using ingredients such as Shudihuang （Rehmanniae Radix Praeparata）， Shanzhuyu （Corni Fructus）， Gouqizi （Lycii Fructus）， Wuweizi （Schisandrae Chinensis Fructus）， and Tusizi （Cuscutae Semen）. These are combined with approaches to harmonize the zang-fu organs， primarily including extinguishing liver wind， clearing heart fire， nourishing kidney water， and strengthening spleen earth， thereby stabilizing ministerial fire and extinguishing endogenous wind. Additionally， emotional regulation and smoothing emotional constraint are essential to improve clinical symptoms in children with ADHD comorbid with tic disorder.

OBJECTIVE To establish the high-performance liquid chromatography （HPLC） fingerprint of Sagina japonica ， and to establish a quantitative analysis of multi-components by single-marker （QAMS） method for simultaneous determination of six componen ts in S. japonica ， aiming to provide references for the quality control of this medicinal herb. METHODS HPLC method was used to establish the fingerprints of 12 batches （No. S1-S12） of S . japonica according to Similarity Evaluation System of Chromatographic Fingerprint of Traditional Chinese Medicine . The similarity evaluation and identification of common peaks were conducted， followed by cluster analysis （CA） and principal component analysis （PCA） for 12 batches of samples. Using vicenin-2 as internal reference， the contents of p-hydroxy cinnamic acid， apigenin-6-C-arabinoside-8-C-glucoside， isoorientin， vitexin and 20-hydroxyecdysone were determined by QAMS method. The results were then compared with those obtained by the external standard method. RESULTS The similarities of HPLC fingerprints for 12 batches of S . japonica ranged from 0.828-0.998. A total of 17 common peaks were calibrated， and 6 common peaks were identified. Specifically， peak 5 was identified as vicenin-2， peak 7 as p-hydroxycinnamic acid， peak 10 as apigenin-6-C-arabinoside-8-C-glucoside， peak 11 as isoorientin， peak 13 as vitexin， and peak 15 as 20-hydroxyecdysone. The results of CA showed that S1-S5， S7 and S9-S11 were clustered into one category， S6 was clustered into one category， and S8 and S12 were clustered into one category. The results of PCA revealed that the accumulative contribution rate of the four main components was 89.430%. The content ranges measured by QAMS method for p-hydroxy cinnamic acid， apigenin-6-C-arabinoside-8-C-glucoside， isoorientin， vitexin and 20-hydroxyecdysone were 0.017 4-0.269 4， 0.568 8-4.240 3， 0.503 2-5.040 3， 0.024 0-0.132 0 and 2.551 3-4.881 1 mg/g， respectively. There was no significant difference in the contents of components measured between QAMS method and the external standard method （ P ＞0.05）. CONCLUSIONS The established HPLC fingerprint and QAMS method can be used for quality evaluation and quality control of S . japonica.

The core pathogenesis of attention deficit hyperactivity disorder （ADHD） lies in deficiency， stasis and stagnation. Deficiency arises from kidney essence depletion and spleen dysfunction in transportation and transformation， leading to inadequate nourishment of the marrow sea. Stasis caused by qi deficiency leads to obstruction in channels and collaterals， resulting in obstructed marrow transport. Stagnation is associated with the excess of the five minds transforming into fire， which scorches the brain orifices and leads to loss of control over marrow utilisation. Based on this， a "supplementation-unblocking-regulation" therapeutic approach is proposed. For deficiency， the focus is on supplementing kidney and fortifying spleen， and replenishing the marrow sea. For stasis， the priority is to unblock and open the orifices， and clear the marrow channels. For stagnation， the core is to clear fire and contain the mind， regulate and restore vital activity. In clinical practice， it is necessary to identify the primary and secondary pathogenic mechanisms and apply dynamic， combined treatment， integrating Chinese herbal medicine， acupuncture， and guiding exercises throughout the process， aiming to provide a reference for the diagnosis and treatment of ADHD with traditional Chinese medical.

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.

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.

This study investigates the clinical differentiation and treatment strategies for bipolar disorder （BD） by analyzing the relationship of its core pathomechanisms including qi stagnation， blood stasis， phlegm turbidity， and heat constraint with bile acid metabolism. The imbalance of "yin in form and yang in function" leads to qi stagnation， blood stasis， phlegm turbidity， and heat constraint， which are critical in the pathogenesis and progression of BD. Bile acids regulate neuroinflammation， neural plasticity， and intestinal flora homeostasis through receptor-mediated pathways. It is believed that the physiological functions of bile acids concretely embody the concept of the "liver is yin in form and yang in function" theory. Clinically， prescriptions such as Sini Powder （四逆散） with the function of venting pathogen and resolving constraint， Wendan Decoction （温胆汤） of drying dampness and resolving phlegm， Longdan Xiegan Decoction （龙胆泻肝汤） of clearing liver and draining fire， and Huanglian Ejiao Decoction （黄连阿胶汤） of nourishing yin and blood can be used to nourish liver yin and restore liver yang function. These strategies may improve BD prognosis by modulating bile acid synthesis and metabolism.

Objective To explore the regulatory effect of Lingzhu Granules on the PI3K/Akt signaling pathway in the rats with polycystic ovary syndrome(PCOS)accompanied by insulin resistance.Methods Fe-male Sprague-Dawley(SD)rats aged 3 weeks d old were selected to establish the model by using the DHEA method.The intervention treatment was administered by different doses of Lingzhu Granules and the homeostasis model as-sessment of insulin resistance(HOMA-IR)was calculated.The relative expression levels of PI3K,Akt,GSK-3β and GLUT4 mRNA in the ovaries was detected by RT-PCR.The expression levels of PI3K and Akt were detected by Western blot.Results Compared with the model control group,the rat body weight in the medium and high doses Lingzhu Granules groups was significantly reduced(P＜0.05).The fasting blood glucose,fasting insulin and HOMA-IR index in the Lingzhu Granules low,medium and high doses groups were significantly lower than those in the model control group,and the differences were statistically significant(P＜0.01).The mRNA relative expression levels of PI3K,Akt,GSK-3β and GLUT4 in the Lingzhu Granules medium and high doses groups all were higher than those in the model control group(P＜0.05).The relative expression levels of PI3K and Akt in the ovarian tissue in the Lingzhu Granules low,medium and high doses groups were higher than those in the model control group,and the differences were statistically significant(P＜0.05).Conclusion Lingzhu Granules could effectively improve the insulin resistance status of PCOS rats by enhancing the synthesis of PI3K and Akt.

Spleen-stomach damp-heat syndrome is currently the most prevalent TCM pattern in patients with chronic atrophic gastritis (CAG), with internal damp-heat accumulation regarded as a key factor contributing to its prolonged and refractory course. This syndrome represents a critical stage in the progressive pathogenesis of CAG, characterized by a deepening pathological evolution. Modern TCM practitioners generally agree that its core pathogenesis lies in "deficiency in root and excess in superficiality, with internal damp-heat retention", and emphasize a treatment strategy that combines eliminating pathogenic factors and reinforcing the body's healthy qi through dynamic syndrome differentiation. Chinese materia medica used in treating CAG with spleen-stomach damp-heat syndrome can effectively relieve clinical symptoms, improve the internal damp-heat environment, mitigate gastric mucosal atrophy and intestinal metaplasia, and delay the inflammation-to-cancer transformation. Its mechanisms may involve eradication of Helicobacter pylori, repair of gastric mucosal injury, regulation of immune inflammatory response and other aspects, which has the advantages of multi-channel and multi-target.

Objective To establish primary breast cancer cell lines from patient tissues and offer a new cancer cell model for basic research.Methods Breast cancer biopsy tissues were digested with typeⅡcollagenase and cultured in BCMI medium.When the cells proliferated rapidly,the medium was switched to DMEM.STR genotyping was per-formed to identify specific genetic markers of the four primary breast cancer cell lines.Colony expansion assays and sphere formation assays were conducted to analyze its tumorigenicity.Real-time PCR and Western blot experiments were used to analyze the expression of the epithelial-mesenchymal transition(EMT)molecule markers.Migration and invasion assays were performed to assess the metastatic potential of the primary breast cancer cells.Results We es?tablished four primary breast cancer cell lines:BC25#,BC51#,BC56#,and BC57#.These cell lines were cultured in DMEM medium,passaged multiple times and tagged with details about their clinical past.STR genotyping identified specific genetic markers for each of the four primary breast cancer cell lines.Clonogenic and sphere formation assays revealed that the four lines have a stronger tumor?forming capability compared to the classic breast cancer cell line T?47D.Real?time PCR and Western blot experiments showed that,compared to T?47D,the four primary breast cancer cell lines have decreased E?cadherin expression and increased vimentin expression.Migration and invasion assays indicated that BC25#had a higher metastatic potential than the traditional breast cancer cell line T?47D.Conclusions Four primary breast cancer cell lines,BC25#,BC51#,BC56#and BC57#are successfully estab?lished,which may act as new cancer cell model for laboratory research of breast cancer.

Objective To investigate the regulation of macrophage polarization and foaminess by homocysteine(Hcy)and its potential underlying mechanisms.Methods ELISA and flow cytometry were used to detect the effect of Hcy treatment on the polarization of macrophages.The contents of various forms of intracellular cholesterol were detected,and the effects of Hcy on intracellular lipid accumulation and ox-LDL uptake were evaluated by oil red O staining and Dil-oxLDL.RT-qPCR and Western blot were used to detect mRNA and pro-tein expression of key genes modified by N6-methyladenosine(m6 A).Results Hcy promoted M1 polarization of macrophages and ox-LDL-induced foam macrophages and promoted ox-LDL uptake as well as intracellular lipid accumulation.In addition,Hcy upregulated methyltransferase like 3(METTL3)expression,and the tendency of Hcy to promote macrophage M1 polarization and foaminess was markedly reduced after inhibition or knockdown of METTL3 expression.Conclusions Hcy significantly promotes macrophage M1 polarization and foaminess,an effectthat may be attenuated by METTL3 silencing.
