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 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.

BACKGROUND: Recent studies have shown that sodium-glucose cotransporters-2 (SGLT2) inhibitors significantly improve major adverse cardiovascular events in heart failure with preserved ejection fraction (HFpEF) patients, but the exact mechanism is unknown. Ferritinophagy is a special form of selective autophagy that participates in ferroptosis. In this study, we aimed to investigate whether ferritinophagy was activated during the occurrence of HFpEF, and whether canagliflozin (CANA) could inhibite ferritinophagy. METHODS: We reared Dahl salt-sensitive (DSS) rats on a high-salt diet to construct a hypertensive HFpEF model, and simultaneously administered CANA intervention. Then we detected indicators related to ferritinophagy. RESULTS: The expression of nuclear receptor coactivator 4 (NCOA4), as well as microtubule-associated proteins light chain 3 (LC3), Bcl-2 interacting protein 1 (Beclin-1) and p62, were upregulated in HFpEF rats, accompanied by the downregulation of ferritin heavy chain 1 (FTH1), upregulation of mitochondrial iron transporter sideroflexin1 (SFXN1) and increased reactive oxygen species (ROS) production. Above changes were diminished by CANA. CONCLUSION Ferritinophagy is activated in HFpEF rats and then inhibited by CANA, leading to HFpEF benefits. The inhibition of ferritinophagy could provide new prospective targets for the prevention and treatment of HFpEF, and provide new ideas for investigating the mechanism of cardiovascular benefit of SGLT2 inhibitors.

Objective:To summarized the clinical characteristics and surgical management of anterior cervical enterogenic in pediatric patients. Methods:Clinical data were retrospectively analyzed for 9 children with pathologically confirmed anterior cervical enterogenic cysts（including bronchogenic and esophagogenic subtypes） treated at the Children's Hospital of Shandong University（Jinan Children's Hospital） between January 1, 2020, and November 30, 2023. Results:Nine patients（6 males and 3 females） were involved in this study, aged 14 days to 10 years old. There were 4 cases on the left side, 4 on the right side, and 1 in the middle of the neck. All patients presented with neck masses. The patients were followed up from 3 months to 35 months after surgery and recovered well, with no recurrence or complications observed. Conclusion:①Anterior intestinal cysts in children are rare and easy to be misdiagnosed. ②Concurrent branchial cleft fistulas or associated anomalies may coexist, necessitating comprehensive evaluation. ③Preoperative diagnosis is not easy and mainly depends on pathological diagnosis. ④The treatment of anterior cervical enterogenic cysts in children is surgical resection of the lesion.

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.

Objective To analyze the medication law and academic thoughts of Professor Wang Junhong in the treatment of tic disorders(TD)in children.Methods The cases of children with TD diagnosed and treated by Professor Wang Junhong from January 2015 to November 2022 were selected.Excel 2016 was used to analyze the clinical information of children with TD.The frequency ranking,property,taste and meridian tropism,and changes of prescription drugs were analyzed in multiple dimensions.SPSS Modeler 18.0 was used to analyze the drug association rules of prescriptions in 2021 and 2022.Cytoscape 3.9.0 was used to analyze the complex network of drug-drug strong,medium and weak links obtained by SPSS Modeler 18.0.The drug groups were obtained in SPSS,and Excel 2016 was used to analyze the annual changes of high-frequency drugs.Results Totally 5586 prescriptions were included,involving 198 kinds of Chinese materia medica,with a total frequency of 108356 times.The top five kinds of high-frequency Chinese materia medica were Chrysanthemi Flos,Acori Tatarinowii Rhizoma,Coptidis Rhizoma,Crataegi Fructus,Polygalae Radix.The medicinal properties were mostly cold,warm and mild.The medicinal tastes were mainly bitter,sweet and pungent.The main meridians of drugs were liver,heart and lung meridians.The association rule analysis showed that the common couplet medicines were Chrysanthemi Flos-Acori Tatarinowii Rhizoma and Acori Tatarinowii Rhizoma-Scorpio.Commonly used triple combination was Chrysanthemi Flos-Scorpio-Acori Tatarinowii Rhizoma.Clustering analysis showed 4 drug groups,reflecting the characteristics of Professor Wang Junhong's treatment of calming liver and tranquilizing mind.According to the time-flow analysis,since 2020,the proportion of drugs such as Bupleuri Radix,Scutellariae Radix,Haliotidos Concha,Gastrodiae Rhizoma and Margaritifera Concha have gradually increased,indicating that more attention should be paid to treating the liver,resolving phlegm and calming the mind.Conclusion In the treatment of TD in children,Professor Wang Junhong takes heart,liver and lung as the center.The prescription medication is to relieve wind and phlegm,soothe the liver and tranquilize the mind.In recent years,it has attached importance to the role of regulating emotions and resolving phlegm in the treatment of children with TD.

Objective To investigate the feasibility of retroperitoneoscopy in the treatment of adrenal masses in infants under 6 months old.Methods From January 2020 to November 2023,retroperitoneoscopic surgery was performed in 5 infants under 6 months old with adrenal tumors.Their age was from 1 month and 18 days to 4 months and 27 days,and their body weight was 5-8 kg.The lesion was found by prenatal ultrasonography in 1 case and by abdominal ultrasonography for other reasons after birth in 4 cases.Ultrasound and CT indicated a diameter of 1.7-5.5 cm for the adrenal masses.Results The operations of adrenalectomy and tumor resection were completed under retroperitoneoscopy.The operative time was 65-135 min(median,94 min).The intraoperative blood loss was less than 10 ml.The postoperative drainage tube retention time was 3-6 d(median,5 d).Pathological diagnosis showed 4 cases of adrenal neuroblastoma and 1 case of adrenal hyperplasia.Follow-ups for 1-36 months(median,3 months)with abdominal ultrasound and CT scanning showed no recurrence or metastasis.Conclusion Retroperitoneoscopy is relatively safe for the treatment of adrenal tumors in infants under 6 months old(tumors with acceptable boundaries).

Objective To summarize the clinical experience of thoracoscopic treatment of anterior mediastinal enterogenous cysts.Methods From July 2019 to July 2023,27 children diagnosed as having anterior mediastinal enterogenous cysts were treated with total thoracoscopic surgery through the lateral thoracic approach(three port method)in our department.The patients were placed in a healthy lateral position.The observation hole was located in the 5th intercostal space under the scapula,and the other 2 operating holes were established based on the location of the lesion and the endoscopic diamond-shaped method,both of which were 5 mm trocars.The CO2 pneumothorax was established at a pressure of 6 mm Hg.The visceral pleura of the cyst was opened with an electric hook,the cyst was fixed and pulled by intestinal forceps,and the cyst was completely removed by forceps and electric hook separation alternately.Results No conversion to thoracotomy was required.Complete resection was performed in 26 cases,and residual cyst wall existed in 1 case.Esophageal muscular layer was opened in 9 cases.During the operation,cysts obstructed the surgical field of view in 5 cases,which was not conducive to observation.The cyst puncture and fluid extraction were performed.The operation time was 45-120 min(median,70 min).The amount of blood loss was 3-10 ml(median,5 ml).Postoperative hospitalization lasted for 2-5 d(median,3d).The 27 cases were followed up for 1-43 months(median,22 months),and there was no recurrence.The compressed trachea in 2 cases was all recovered,with emphysema fully recovered.Conclusions Thoracoscopic treatment of anterior mediastinal enterogenous cysts in children is safe and feasible.When the surrounding structure of the lesion is complex,it can be combined with bronchoscopic or gastroscopic surgery if necessary.

In mass spectrometry-based proteomics experiments,achieving high-throughput and efficientproteolytic digestion is crucial to ensure optimal protein cleavage and enhance the depth of protein identi-fication (including the number of identified proteins and the coverage of protein amino acid sequences) .Trypsin is the most widely used protease in mass spectrometry-based proteomics due to its ability to spe-cifically cleave the carboxyl terminus of arginine and lysine.However,it was found that Trypsin has some missed enzymatic efficiency for the cleavage of lysine residues.Therefore,in actual proteomics sample preparation,a combination of Trypsin and LysC will be used to ensure adequate cleavage of lysine resi-dues.Our study revealed that the commonly employed LysC-Trypsin tandem cleavage method exerts an impact on the enzymatic cleavage of protein samples by Trypsin due to the subsequent cleavage of Trypsin by initially added LysC.Consequently,we adjusted the order of LysC and Trypsin tandem digestion,with Trypsin cleavage being performed first followed by the addition of LysC to target any missed lysine resi-dues.We comprehensively compared and analyzed three distinct sequential digestion methods,namely Trypsin-Trypsin (T-T),LysC-Trypsin (L-T),and Trypsin-LysC (T-L),in terms of their effects on pro-tein sample preparation quality.The results demonstrated that the Trypsin-LysC sequential digestion ap-proach not only minimizes missed protein lysine/arginine cleavage sites without increasing experimental costs,at the same time yielding peptides with a moderate amino acid sequence length.The use of Tryp-sin-LysC digestion enhances the adsorption and separation of peptide samples in RP-HPLC,as well as improves the depth of protein detection and amino acid sequence coverage during tandem mass spectrome-try analysis.This research work offers a novel technical solution and serves as a valuable reference for proteome sample preparation.
