The primary approach for clinical treatment of short stature （SS） in children is the use of recombinant human growth hormone （rhGH）. However， the high cost of treatment and the daily injection frequency place a significant economic and psychological burden on the families of affected children. For SS adolescents who have missed the peak growth velocity period of puberty， the use of rhGH alone is also difficult to significantly increase their final adult height. Numerous studies have shown that aromatase inhibitors （AIs） are effective in improving the height of SS boys， especially the combination therapy of AIs and rhGH， which has a better effect. Although the use of AIs may affect the children’s bones， cognitive function， reproductive system and hormone levels， most of these effects are temporary. Since existing research has not fully elucidated its impact on the pubertal changes of girls， it is necessary to fully weigh the benefits and risks when using AIs to treat SS girls in clinical practice. In the future， it is also necessary to carry out pharmacoeconomic research based on the medical environment of China to evaluate the cost- effectiveness of AIs for SS in children.

OBJECTIVE To investigate the effect of Jianpi Yangzheng(JPYZ)formula regulating tumor-associated macrophage(TAM)exosomes on anoikis in gastric cancer and its mechanism.METHODS TAM model was established by inducing human mononuclear THP-1 cells in vitro;M0,TAM and TAM+JPYZ formula exosomes were extracted by ultracentrifugation and co-incuba-ted with gastric cancer cells.Flow cytometry was used to detect the effect of exosomes in each group on anoikis in gastric cancer cells.A BALB/c transplanted tumor mouse model was constructed,and the expression level of apoptotic proteins in transplanted tumors was detected by Western blot.Label-free mass spectrometry proteomics and bioinformatics were used to analyze the differential proteins in gastric cancer cells before and after intervention;Western blot and qPCR experiments were used to detect the expression level of dif-ferential protein isocitrate dehydrogenase 1(IDH1),and ubiquitination experiments were used to detect the ubiquitination level of IDH1;kits were used to detect the levels of α-ketoglutarate(α-KG),NADPH/NADP+,glutathione(GSH/GSSG)and reactive oxy-gen species(ROS)content.RESULTS The anoikis rate of gastric cancer cells was reduced after TAM exosomes intervention(P<0.05,P<0.01),while it was significantly increased after TAM+JPYZ exosomes intervention(P<0.05,P<0.01).In the in vivo mouse experiment,the ratio of Cleaved Caspase-3/Caspase-3 in the tumor of the TAM exosome group was reduced(P<0.05),while the ra-tio was significantly increased after TAM+JPYZ exosome intervention(P<0.05).Proteomic analysis showed that IDH1 was significant-ly different after intervention,and was related to tricarboxylic acid cycle metabolism.Compared with the M0 group,the IDH1 ubiquiti-nation level of gastric cancer cells in the TAM group with exosome intervention was increased,the levels of α-KG,NADPH/NADP+and GSH/GSSG were significantly increased,and the ROS content was reduced(P<0.05),while TAM+JPYZ exosomes could reverse the above phenomenon.CONCLUSION JPYZ Formula can regulate TAM exosomes to cause ubiquitin degradation of IDH1 in gas-tric cancer cells,reduce the level of tricarboxylic acid cycle metabolism in gastric cancer cells,promote ROS accumulation,induce anoikis in gastric cancer,and thus inhibit the development of gastric cancer.

This paper summarized the clinical experience of Professor LIU Shenlin in diagnosing and treating gastric cancer with the thinking of "prescription according to tendency". In this paper， the thinking of diagnosis and treatment for gastric cancer and medication skills were summarized into four dimensions： power， energy， chronology and situation. The diagnosis emphasizes the tendency of qi power， considering that the onset of gastric cancer primarily stems from the disorder of qi movement in zang-fu organs， and emphasizing the importance of regulating the liver and spleen qi to intercept the tendency of disease. It points out that dampness-phlegm-stasis-toxin is a crucial link leading to the metabolic imbalance of body energy， and Professor LIU adepts at using methods such as breaking up blood and expelling stasis， and clearing heat and resolving toxins to block the pathological chain reaction caused by energy imbalance and to restore the homeostasis of the organism. In the treatment process， according to the characteristics of gastric cancer staging and chronological evolution， we will explore the changes of the exuberance and weakness of healthy qi and pathogenic qi in the context of the chronologic tendency， and adjust the dosage of attacking and tonic medicines in different stages of the disease in order to balance and restore the body. The "situation" is in line with the state of consumptive disease in advanced gastric cancer， Professor LIU skillfully uses large doses of Huangqi （Astragalus mongholicus） with flexible combination of medicinals to replenish deficiencies， invigorate qi， and regulate blood vessels.

Background Occupational hazards in the workplace are often determined through on-site investigations and recognized hazards to determine monitoring items, and occupational health risk assessments are rarely carried out on the monitoring results. Objective Based on the qualitative results of volatile organic compounds, to monitor 8 types of volatile organic compounds in workplace air, and conduct occupational health risk assessments for workstations with disqualified results. Methods This study selected 29 enterprises from 12 key industries listed in the Work Plan for Monitoring Occupational Disease Hazards in Workplaces in Chongqing (2023) in 5 districts and counties of Chongqing. A total of 49 key workstations, including spray painting, glue brushing, glue adjustment, adhesion, printing, bonding, packing, oil film, feeding, material preparation,dispersion, and immersion, were selected for air sampling and chemical headspace treatment. The volatile organic compounds in the headspace were separated with a gas chromatography capillary column and sequentially entered into a mass spectrometer for detection. Qualitative analysis of each component was conducted using the National Institute of Technical Standards and Technology standard spectrum library and retention time. Based on the qualitative results, chemical hazards and related workstations were determined, then quantitative evaluation was conducted for key hazards in workplace air, and followed by occupational health risk assessment for the disqualified workstations using semi-quantitative exposure ratio. Results One or more of the 8 key chemical hazards were positive in the 29 enterprises, among which xylene (89.7%) and toluene (86.2%) had the highest positive rates, followed by benzene (34.5%), 1,2-dichloroethane (31.0%), ethylbenzene (20.7%), n-hexane (10.3%), and trichloromethane (6.9%), and trichloroethylene was negative. In the quantitative evaluation for occupational hazards in workplace air, the highest positive rates of chemical hazards were xylene (70.6%) and ethylbenzene (83.3%), and the highest disqualification rate of chemical hazards was 1,2-dichloroethane (50.0%). Out of the 29 enterprises, 8 reported disqualified air key chemical hazards, mainly in the workstations of spray painting and immersion. One spray painting workstation reported 3 disqualified chemical hazards, and one spary painting workstation reported 2 disqualified chemical hazards. The risk level of 1,2-dichloroethane in the spary painting workstations of 3 enterprises was high. The joint risk of 2 enterprises with multiple disqualified chemical hazards was high. Conclusion The positive rates of benzene derivatives and 1,2-dichloroethane in workplace chemicals are high in this study. The risk level of 1,2-dichloroethane in the spary painting workstations of 3 companies is high, and this substance needs special attention in future monitoring.

Objective To explore whether voluntary wheel running affects liver oxidative stress by regulating the Nrf2/HO-1 pathway,thereby alleviating HFFC diet-related lipid deposition in the liver.Methods Eight-week-old C57BL/6J mice were randomly divided into a normal diet group(NC group,n=10)and high-fat,fructose,and cholesterol diet group(HFFC group,n=20)after 1 week of adaptive feeding.Ten weeks of feeding later,mice in the HFFC group were divided into a quiet group(HFFC group,n=10)and HFFC combined with exercise group(HFFC+EX group,n=10).HFFC+EX group mice were caged with voluntary running wheels for free movement,and the number of running wheels was recorded every day for 8 weeks.After the last treatment,the mice were sacrificed by fasting for 12 hours at an interval of 24 hours,and the blood and liver were collected for analysis.Results(1)Body weight,liver weight,and liver index of mice fed the HFFC diet were significantly higher than those of the NC group,which significantly decreased after exercise(P＜0.05).(2)Compared with the NC group,HDL-C and LDL-C in the HFFC group were significantly increased,and the LDL-C level was significantly decreased after 8 weeks of exercise(P＜0.05).(3)The liver fat droplet area and liver TG content in the HFFC group were significantly higher than those in the NC group,whereas those in HFFC+EX group were significantly decreased(P＜0.05).(4)Compared with the NC group,the content of oxidase MDA in the HFFC group were significantly increased,and nuclear translocation and gene expression of Nrf2 were significantly decreased.After exercise,the activities of SOD and T-AOC were significantly increased,and the nuclear translocation and gene expression of Nrf2 and expression levels of HO-1 and SOD-1 were significantly increased(P＜0.05).(5)The number of apoptotic hepatocytes and CHOP expression in the HFFC diet group were significantly higher than those in the NC group,whereas the number of apoptotic hepatocytes,and CHOP and Bax/Bcl-2 expression in the exercise group were significantly lower than those in the NC group(P＜0.05).Conclusions Voluntary wheel can alleviate HFFC diet induced liver lipid deposition by regulating the Nrf2/HO-1 pathway,thereby alleviating oxidative stress and reducing apoptosis in liver cells.

Background::Genetic variants of dopaminergic transcription factor-encoding genes are suggested to be Parkinson’s disease (PD) risk factors; however, no comprehensive analyses of these genes in patients with PD have been undertaken. Therefore, we aimed to genetically analyze 16 dopaminergic transcription factor genes in Chinese patients with PD.Methods::Whole-exome sequencing (WES) was performed using a Chinese cohort comprising 1917 unrelated patients with familial or sporadic early-onset PD and 1652 controls. Additionally, whole-genome sequencing (WGS) was performed using another Chinese cohort comprising 1962 unrelated patients with sporadic late-onset PD and 1279 controls.Results::We detected 308 rare and 208 rare protein-altering variants in the WES and WGS cohorts, respectively. Gene-based association analyses of rare variants suggested that MSX1 is enriched in sporadic late-onset PD. However, the significance did not pass the Bonferroni correction. Meanwhile, 72 and 1730 common variants were found in the WES and WGS cohorts, respectively. Unfortunately, single-variant logistic association analyses did not identify significant associations between common variants and PD. Conclusions::Variants of 16 typical dopaminergic transcription factors might not be major genetic risk factors for PD in Chinese patients. However, we highlight the complexity of PD and the need for extensive research elucidating its etiology.

Objective:To evaluate the efficacy of visualized precise lung expansion for determining the intersegmental plane in thoracoscopic segmentectomy.Methods:Sixty-four American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, regardless of gender, aged 33-77 yr, with body mass index of 16-34 kg/m 2, undergoing elective thoracoscopic segmentectomy under general anesthesia, were included. They were preoperatively reconstructed with 3D CT bronchovascularization to reconstruct the pulmonary vasculature, bronchus, and the virtual intersegmental planes of the lungs. The patients were divided into 2 groups ( n=32 each) using a random number table method: visualized precise lung expansion group (group V) and modified expansion and atrophy group (group E). Group V used visualized precision lung expansion to determine the intersegmental planes, and group E used the modified expansion and atrophy method to determine the intersegmental planes. The intraoperative intersegmental plane determination time, target segmental bronchus identification and treatment time, anesthesia time, operation time, postoperative air leakage, pulmonary atelectasis, fever, occurrence of lung infection, postoperative 24 h drainage volume, drain removal time and hospitalization time were recorded in the two groups. Results:Compared with group E, the intersegmental plane determination time, target segment bronchial identification and treatment time, anesthesia time and operation time were significantly shortened in group V( P<0.05).There were no significant differences between groups in the 24 h postoperative drainage volume, drain removal time, hospitalization time or incidence of postoperative pulmonary complications ( P>0.05). Conclusions:Compared with the modified expansion and atrophy method, visualized precise lung expansion can effectively shorten the intersegmental plane determination time in thoracoscopic segmentectomy.

Abstract: Objective　To find out the causes and risk factors of this food-borne disease outbreak that occurred in November 2019 at four schools in Qinzhou, Guangxi, implement effective preventive and control measures to curb the spread and escalation of the outbreak, and provide a basis for the investigation and management of similar incidents in the future. Methods　Descriptive epidemiological methods were used to analyze the cases' clinical characteristics, three-dimensional distribution, and related risk factors. The etiological food was determined by the method of analytical epidemiology. A food hygiene investigation was conducted to trace the process of food contamination, and biological samples from cases and workers, suspicious food, and environmental samples were collected for laboratory testing. The detected Salmonella strains were analyzed for homogeneity using pulsed-field gel electrophoresis (PFGE). Results　The event involved four schools, with 69 suspected cases identified, resulting inan attack rate of 0.52% (69/13 307). The main clinical symptoms were abdominal pain, diarrhea, and fever, with an average incubation period of 20 hours.The epidemic curve indicated a point-source outbreak. Descriptive epidemiological methods inferred that bakery products distributed by Company F were the suspect foods. The case-control study indicated the risk of illness was increased among those who purchased and consumed food supplied by Company F (OR=37.67, 95%CI:14.03-101.13),particularly those who consumed the delicious hamburger (OR=30.13，95%CI:13.22-68.67). Salmonella Enteritidis (SE) was detected in 12 anal swabsfrom patients, one patient's vomit, one flour sample used for bread-making, and one egg,with homogeneity of 100% achieved in PFGE molecular typing of the 15 positive Salmonella strains. Conclusions　The outbreak is a food-borne disease outbreak caused by Salmonella contamination. It is recommended that regulatory authorities strengthen supervision and management of production and processing enterprises, standardize food processing processes, and establish and improve food safety management systems and long-term mechanisms for food safety knowledge promotion and education in schools to enhance students' hygiene awarenessand prevent similar incidents from occurring.

Monkeypox is a zoonotic disease.Previous studies have shown that children are vulnerable to monkeypox and are also at high risk for severe disease or complications.In order to improve pediatricians′ understanding of monkeypox and achieve early detection, early diagnosis, early treatment and early disposal, the committee composed of more than 40 experts in the related fields of infectious diseases, pediatrics, infection control and public health formulate this expert consensus, on the basis of the latest clinical management and infection prevention and control for monkeypox released by the World Health Organization (WHO), the guidelines for diagnosis and treatment of monkeypox (version 2022) issued by National Health Commission of the People′s Republic of China and other relevant documents.During the development of this consensus, multidisciplinary experts have repeatedly demonstrated the etiology, epidemiology, transmission, clinical manifestations, laboratory examinations, diagnosis and differential diagnosis, treatment, discharge criteria, prevention, case management process and key points of prevention and control about monkeypox.

The occurrence and development of chronic insomnia involves subjective and objective factors, which can be classified as predisposing factors, precipitating factors and perpetuating factors. Cognitive behavioral therapy for insomnia (CBT-I) evolves from the pathopsychological analysis of chronic insomnia patients, and selectively combines the sleep hygiene, cognitive therapy and behavioral therapy to improve the symptoms of patients. With the popularity of internet, the digital cognitive behavioral therapy for insomnia has an convenient advantage over the traditional therapy, and has become the focus of research. Researchers have proposed multiple therapies for chronic insomnia, including drug therapy and non-drug therapy, which improve the treatment effect of chronic insomnia from different perspectives.
