Acute Gelsemium poisoning is a systemic disease primarily affecting the central nervous system and respiratory symptoms caused by the ingestion of a substantial amount of Gelsemium within a short period. It manifests as sudden onset and rapid progression, primarily caused by accidental ingestion due to misidentification, and posing significant health risks. The compilation of the Technical Plan for Emergency Health Response to Acute Gelsemium Poisoning describes in detail the specialized practice and technical requirements in the process of handling acute Gelsemium poisoning, including accident investigation and management, laboratory testing and identification, in-hospital treatment, and health monitoring. The guidelines clarify key procedures and requirements such as personal protection, investigation elements, etiology determination, medical rescue, and health education. The key to acute Gelsemium poisoning investigation lies in promptly identifying the toxin through exposure history, clinical manifestations, and sample testing. Because there is no specific antidote for Gelsemium poisoning, immediate removal from exposure, rapid elimination of the toxin, and respiratory monitoring are critical on-site rescue measures. Visual identification of food or herbal materials, followed by laboratory testing to determine Gelsemium alkaloids in samples is a rapid effective screening method. These guidelines offer a scientific, objective, and practical framework to support effective emergency responses to acute Gelsemium poisoning incidences.

Objective: To explore the association between physical activity, anxiety symptoms and academic performance among junior high school students, so as to provide data support for optimizing school physical education and health work and formulating physical activity guidelines. Methods: From September to December 2022, a convenience cluster sampling method was used to survey 2 800 junior high school students in a middle school from Anqing City, Anhui Province. Data were collected on the students anxiety symptoms, academic performance, 24 hour physical activity [moderate to vigorous intensity physical activity(MVPA), light intensity physical activity(LPA), sedentary behavior(SB), and sleep(SLP) duration] as well as demographic characteristics. Compositional data analysis was used to explore the associations between 24 hour physical activity, anxiety symptoms and academic performance among junior high school students, and to predict the optimal time use combination pattern. Results: Among the junior high school students, 16.0% (447 students) reported anxiety symptoms, and 42.0% (1 175 students) achieved excellent or good academic performance. Compositional data analysis showed that increased SLP duration was associated with both reduced anxiety symptoms ( β =-0.18) and decreased academic performance ( β =-0.03) among junior high school students; increased MVPA duration was correlated with fewer anxiety symptoms ( β =-0.02) and lower academic performance ( β =-0.13); in contrast, increased SB duration was linked to more anxiety symptoms ( β =0.09) and higher academic performance ( β =0.09) (all P <0.01). LPA duration exhibited a non linear relationship with anxiety symptoms and academic performance in junior high school students (all P >0.05). The time use combination pattern corresponding to the lowest anxiety symptoms and highest academic performance (top 5%) in adolescents was 611 (520-640) minutes of SLP, 258 (230-320) minutes of SB, 454 (280-610) minutes of LPA, and 117 (20-200) minutes of MVPA per day. Conclusions The 24 hour physical activity of junior high school students is associated with anxiety symptoms and academic performance. Therefore, it is recommended to increase the time spent on SB, MVPA, and LPA for junior high school students, while reducing SB.

Myelodysplastic syndrome (MDS) is a malignant hematologic tumor, which is currently difficult to cure. The theory of Xuanfu was proposed by Liu Wansu, which is unique in the clinical evidence of Chinese medicine and is less frequently applied to hematological diseases. The application of Xuanfu theory in myelodysplastic syndrome provides new ideas for the treatment of the disease. The abnormal flow of Qi, blood and fluids caused by the occlusion of the Xuanfu is the cause of toxic stasis obstruction, which is the pathogenesis of toxic stasis obstruction. Thus, the method of dispersion of Bone from Xuanfu, the external treatment of Xuanfu, and regulation of liver qi and Xuanfu help to return to normal of opening and closing function of Xuanfu, and release toxic stasis. In this paper, we analyzed the evidence of toxin-stasis obstruction in myelodysplastic syndrome from the theory of Xuanfu, aiming to provide a feasible theoretical basis for clinical treatment of the disease.

ObjectiveTo observe the therapeutic effect of Qiwei Baizhusan（QWBZS） on diabetic encephalopathy（DE） rat model， and to explore the possible mechanism of QWBZS in the treatment of DE based on phosphatidylinositol 3-kinase（PI3K）/protein kinase B（Akt）/glycogen synthase kinase-3β（GSK-3β） signaling pathway. MethodForty-eight SPF male Wistar rats were randomly divided into blank group（8 rats） and high-fat diet group（40 rats）. After 12 weeks of feeding， rats in the high-fat diet group were intraperitoneally injected with 35 mg·kg^-1 of 1% streptozotocin（STZ） for 2 consecutive days to construct a DE model， and rats in the blank group were injected with the same amount of sodium citrate buffer. After successful modeling， according to blood glucose and body weight， model rats were randomly divided into model group， low， medium and high dose groups of QWBZS（3.15， 6.3， 12.6 g·kg^-1）， combined western medicine group（metformin+rosiglitazone， 0.21 g·kg^-1）， with 6 rats in each group. The administration group was given the corresponding dose of drug by gavage， and the blank group and the model group were given an equal volume of 0.9% sodium chloride solution by gavage， 1 time/day for 6 weeks. Morris water maze was used to detect the spatial memory ability of DE rats. Fasting insulin （FINS） level was detected by enzyme-linked immunosorbent assay（ELISA） and insulin resistance index（HOMA-IR） was calculated. Hematoxylin-eosin（HE） staining was used to observe the morphological changes of hippocampus in rats， ELISA was used to detect the indexes of oxidative stress in hippocampal tissues， real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） was used to detect mRNA expression levels of PI3K， Akt， nuclear transcription factor-κB（NF-κB）， tumor necrosis factor-α（TNF-α） and interleukin-1β（IL-1β） in hippocampus， and Western blot was used to detect the protein expression of PI3K， Akt， phosphorylated（p）-Akt， GSK-3β and p-GSK-3β in hippocampus of rats. ResultCompared with the blank group， FINS and HOMA-IR values of the model group were significantly increased（P<0.01）， the path of finding the original position of the platform was significantly increased， and the escape latency was significantly prolonged（P<0.01）， the morphology of neuronal cells in hippocampal tissues was disrupted， the levels of reactive oxygen species（ROS） and malondialdehyde（MDA） in hippocampus of rats were increased， and the activity of superoxide dismutase（SOD） was decreased（P<0.05， P<0.01）， mRNA expression levels of PI3K and Akt were decreased（P<0.01）， mRNA expression levels of NF-κB， TNF-α and IL-1β were increased（P<0.05， P<0.01）， the protein expression levels of PI3K， p-Akt and p-GSK-3β were significantly decreased， and the protein expression of GSK-3β was significantly increased（P<0.01）. Compared with the model group， the FINS and HOMA-IR values of the medium dose group of QWBZS and the combined western medicine group were significantly decreased（P<0.01）， the path of finding the original position of the platform and the escape latency were significantly shortened（P<0.01）， the hippocampal tissue structure of rats was gradually recovered， and the morphological damage of nerve cells was significantly improved， the contents of ROS and MDA in hippocampus of rats decreased and the level of SOD increased（P<0.01）， the mRNA expression levels of PI3K and Akt were increased（P<0.01）， and the mRNA expression levels of NF-κB， TNF-α and IL-1β were decreased （P<0.05， P<0.01）， the protein expression levels of PI3K， p-Akt and p-GSK-3β were significantly increased（P<0.01）， and the expression of GSK-3β was significantly decreased（P<0.01）. ConclusionQWBZS can alleviate insulin resistance in DE rats， it may repair hippocampal neuronal damage and improve learning and cognitive ability of DE rats by activating PI3K/Akt/GSK-3β signaling pathway.

BACKGROUND:Plastic as a durable,inexpensive,easy to manufacture organic synthetic polymer materials are widely used.At the same time,plastic resistance to high temperatures,acid and alkali resistance,corrosion-resistant properties make it difficult to degrade in nature,and ultimately forming a huge number of microplastic pollution threatening human health. OBJECTIVE:To investigate the effects of microplastic exposure on growth and development and hepatic lipid metabolism in mice. METHODS:Twenty C57BL/6J male mice were adaptively fed for one week,and then randomly divided into normal and microplastic groups(n=10 per group).Mice in the normal group were given a normal diet and water,for 4 weeks.Mice in the microplastic group were given a normal diet and free drinking of microplastic(polystyrene)water with a concentration of 1 000 μg/L,for 4 weeks.At 2 and 4 weeks of drinking,body mass and grip strength,blood lipids and liver and kidney function,ultrasonic morphology and pathological morphology of liver and lipid deposition were detected. RESULTS AND CONCLUSION:(1)With the extension of time,the body mass of mice in the two groups gradually increased,and the body mass of mice in the microplastic group was greater than that in the normal group after 2,4 weeks of drinking water(P<0.05).With the extension of time,the grip strength of mice in the normal group gradually increased,and the grip strength of mice in the microplastic group first decreased and then increased,and the grip strength of mice in the microplastic group was lower than that in the normal group after drinking water for 4 weeks(P<0.05).(2)Liver ultrasound examination showed that compared with the normal group,the ultrasonic echo signal of the liver in the microplastic group was enhanced after 2 and 4 weeks of drinking water.(3)Hematoxylin-eosin staining showed that the morphology of liver cells in the microplastic group did not change significantly after 2 and 4 weeks of drinking water,but inflammatory cell infiltration could be seen.Oil red O staining showed that obvious lipid deposition was observed in the liver of microplastic group after 2 and 4 weeks of drinking water.(4)Compared with the normal group,the levels of serum high density lipoprotein cholesterol,triacylglycerol,and aspartate aminotransferase in the microplastic group were decreased after 2 weeks of drinking water(P<0.05),and the serum triacylglycerol concentration was decreased after 4 weeks of drinking water(P<0.05).(5)These findings confirm that microplastics may cause weight gain,loss of physical strength,and abnormal hepatic lipid metabolism in mice.

Objective To investigate the relationship of miRNA gene polymorphisms with blood pressure(BP)responses to the sodium and potassium diet intervention.Methods In 2004,we recruited 514 participants from 124 families in seven villages of Baoji,Shaanxi Province,China.All subjects were given a three-day normal diet,followed by a seven-day low-salt diet,a seven-day high-salt diet,and finally a seven-day high-salt and potassium supplementation.A total of 19 miRNA single nucleotide polymorphisms(SNPs)were selected for analysis.Results Throughout the sodium-potassium dietary intervention,the BP of the subjects fluctuated across all phases,showing a decrease during the low-salt period and an increase during the high-salt period,followed by a reduction in BP subsequent to potassium supplementation during the high-salt diet.MiR-210-3p SNP rs 12364149 was significantly associated with systolic BP(SBP),diastolic BP(DBP)and mean arterial pressure(MAP)responses to low-salt diet.MiR-4638-3p SNP rs6601178 was significantly associated with SBP while miR-26b-3p SNP rs115254818 was significantly associated with MAP responses to low-salt intervention.In addition,miR-26b-3p SNP rs115254818 was significantly correlated with SBP,DBP and MAP responses to high-salt intervention.MiR-1307-5p SNPs rs1 1191676 and rs2292807 were associated with SBP and MAP responses to high-salt diet.MiR-4638-3p SNP rs6601178,miR-210-3p SNP rs12364149,miR-382-5p SNP rs4906032 and rs4143957 were significantly associated with SBP response to high-salt diet.In addition,miR-26b-3p SNP rs115254818 was significantly associated with SBP,DBP and MAP responses to potassium supplementation.MiR-1307-5p SNPs rs11191676,rs2292807,and miR-19a-3p SNP rs4284505 were significantly associated with SBP responses to high-salt and potassium supplementation.Conclusion miRNA gene polymorphisms are associated with BP response to sodium and potassium,suggesting that miRNA genes may be involved in the pathophysiological process of salt sensitivity and potassium sensitivity.

Objective To explore the effect of miR-1-3p on the malignant biological behavior of human esophageal squamous cell carcinoma cells and the potential mechanisms.Methods The Gene Expression Omnibus(GEO)database was analyzed to screen differentially expressed miRNAs in esophageal squamous cell carcinoma(ESCC).qRT-PCR was used to detect the expression of miR-1-3p in human ESCC cell lines(KYSE30,KYSE150,KYSE410,KYSE510,and Eca109)and normal esophageal epithelial cell line HET-1A.CCK-8,wound healing,Transwell assays,and flow cytometry were applied to detect the effect of miR-1-3p on the proliferation,migration,invasion,and apoptosis of ESCC cells.Bioinformatics tool was used to predict the target genes of miR-1-3p.A Kaplan-Meier survival curve was drawn to analyze the correlation between STC2 expression and overall survival of patients in the ESCC cohort of the TCGA database.Fluorescence in situ hybridization was performed to verify the subcellular location of miR-1-3p in ESCC cells,and dual-luciferase reporter gene assay was performed to validate the regulation of miR-1-3p on stanniocalcin 2(STC2).RNA immunoprecipitation assays were used to detect the binding of miR-1-3p and STC2.Western blot assay was performed to determine the effect of miR-1-3p on the expression of STC2 and endoplasmic reticulum stress pathway-related proteins,including p-PERK,p-eIF2α,and ATF4.CCK-8,wound healing,Transwell assays,and flow cytometry were applied to detect the effect of STC2 overexpression and knockdown on the proliferation,migration,invasion,and apoptosis of ESCC cells.Results The expression of miR-1-3p was lower in ESCC cell lines than in HET-1A cells(all P<0.05).The transfection of miR-1-3p mimic decreased the proliferation,invasion,and migration of ESCC cells(all P<0.05)and promoted the apoptosis of ESCC cells(all P<0.001).Bioinformatics tool showed that STC2 was a target gene of miR-1-3p.The expression of STC2 in ESCC tissues was higher than that in normal esophageal epithelial tissues in the ESCC cohort of TCGA database and was negatively correlated with prognosis(all P<0.05).miR-1-3p was located in the cytoplasm and can directly bind to STC2 mRNA.The transfection of miR-1-3p mimic downregulated the expression of STC2,p-PERK,p-eIF2α,and ATF4(all P<0.05).The overexpression of STC2 promoted the proliferation,invasion,and migration(all P<0.05)and inhibited the apoptosis of ESCC cells(all P<0.05).Knockdown of STC2 inhibited the proliferation,invasion,and migration(all P<0.05)and promoted the apoptosis of ESCC cells(all P<0.05).Conclusion miR-1-3p inhibits the malignant biological behavior and promotes the apoptosis of esophageal squamous cell carcinoma cells by regulating STC2 possibly by suppressing the endoplasmic reticulum stress.

Objective:To evaluate the effectiveness of Z-plasty combined with auricular cartilage grafting in the correction of cryptotia.Methods:A retrospective analysis was conducted on the clinical data of cryptotia patients who underwent Z-plasty combined with auricular cartilage grafting at the Department of Ear Reconstruction, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, from January 2020 to December 2023. The surgery consisted of five steps: design of the Z-plasty flap, harvesting of auricular cartilage from the conchal cavity, dissection and reshaping of the auricular cartilage, transplantation of auricular cartilage, and skin coverage with flap transfer. Early and late complications were recorded according to postoperative follow-up, and the external ear morphology was evaluated by both plastic surgeons and the patients’ guardians using a Likert 4-point scale (the higher the score, the better the auricular morphology). Normally distributed data were presented as Mean±SD.Results:A total of 32 patients were included in the study, comprising 23 males and 9 females, aged 5 to 14 years, with an average age of 7.3 years. Two children were lost to follow-up, and 30 completed long-term follow-up, with follow-up periods ranging from 6 to 24 months, averaging 9.3 months. Early complications included hematoma in 2 cases [6.3%(2/32)] and flap vascular compromise in 1 case[3.1%(1/32)]. Late complications primarily involved hypertrophic scars in 2 cases[6.7%(2/30)], with no recurrence of deformity. After the operation, the cranioauricular sulcus on the upper pole of the auricle were significantly deepened, and the patients could wear masks and glasses. The average score for the external ear morphology was 3.5±0.5 by plastic surgeons and 3.5±0.5 by patients.Conclusion:Z-plasty combined with auricular cartilage grafting provides satisfactory result in the correction of cryptotia, with few postoperative complications and high patient satisfaction, making it suitable for the treatment of cryptotia.
