bjective To analyze the growth trends of height and weight among primary and secondary school students, and explore the developmental characteristics and gender differences at different age groups, and to provide a scientific basis for adolescent health policy formulation. Methods Based on 675 175 health examination records of 227 978 students aged 6-17 years in Shiyan City from 2015 to 2024, a logistic growth model was employed to fit the curves of height and weight changes with age. Results From 2015 to 2024, height and weight showed steady increases across all age groups, exhibiting typical sigmoidal growth patterns. The growth rates varied across age groups: the younger age group (6-9 years) showed a moderate growth (annual height increase of 0.5-1.0 cm, weight increase of 0.03-0.06 kg/year), while the older age group (10-17 years) demonstrated a significant growth (annual height increase of 1.5-2.0 cm, weight increase of 0.22-0.38 kg/year). The growth rate curves displayed a unimodal distribution. The growth inflection points of male students occurred later than that of female students (height inflection point: 9.87 years for males vs. 8.98 years for females; weight inflection point: 10.70 years for males vs. 9.99 years for females). Female students experienced a more concentrated but shorter period of growth and development. The peak height growth rate was 7.40 cm/year at age 9 for females and 7.09 cm/year at age 10 for males, while the peak weight growth rate was 5.04 kg/year at age 10 for females and 5.27 kg/year at age 11 for males. Conclusion The physical development of primary and secondary school students in Shiyan City follows a logistic growth pattern, with significant gender differences and characteristics of adolescent growth spurts. Female students exhibit an earlier and more concentrated growth process.

Background: and Purpose In patients with large vessel occlusion (LVO), intravenous thrombolysis (IVT) frequently alters thrombus location; however, the clinical impact of this phenomenon remains unclear. We aimed to compare post-IVT thrombus dynamics between tenecteplase and alteplase and to evaluate the association between thrombus dynamics and 3-month outcomes. Methods: This retrospective study analyzed prospectively collected, multicenter data from consecutive patients with LVO who underwent bridging therapy between January 2022 and December 2024. Thrombus dynamics were classified as resolution, migration, or stability. Analyses incorporated propensity score matching with weighting to balance baseline characteristics. Results: Of the 806 initially included patients, 746 were included after matching (373 treated with tenecteplase and 373 treated with alteplase). The incidence of thrombus migration was significantly higher in the tenecteplase group than in the alteplase group (19.3% vs. 11.3%; odds ratio [OR]: 1.92; 95% confidence interval [CI] 1.27–2.91). The advantage of tenecteplase over alteplase was restricted to patients with an IVT-to-puncture time of <60 minutes (18.6% vs. 6.2%; p=0.001) and was no longer significant when the interval ≥60 minutes (19.7% vs. 15.0%; p=0.204; pinteraction=0.043). Additionally, thrombus migration was associated with a better functional outcome (OR: 1.62; 95% CI 1.04–2.53). Finally, tenecteplase was associated with improved functional independence compared with alteplase (OR: 1.43; 95% CI 1.04–1.95). Conclusions Tenecteplase demonstrated superior efficacy in inducing thrombus migration compared with alteplase, particularly within 60 minutes of IVT administration. Thrombus migration independently predicted improved functional independence. These findings support the preferential use of tenecteplase for bridging therapy in patients with LVO.

Recent advances in vital pulp therapy(VPT)research,coupled with the widespread use of biomaterials,have led to an in-crease in the application of VPT.The indications for VPT are continually expanding,particularly for fully developed permanent teeth.Currently,one-way membrane decompression is being investigated as a possible treatment to preserve vital pulp in cases of irreversible pulpitis.This technology involves creating an access point in the pulp cavity and using the one-way membrane to prevent microorganisms from invading the pulp tissue.Additionally,it helps alleviate the high pressure in the pulp cavity caused by inflammation,thereby en-hancing blood circulation within the pulp.This improvement is crucial for establishing a foundation for future vital pulp preservation treatments.A case of irreversible pulpitis caused by caries was reported,in which the dental pulp was preserved using the one-way membrane decompression.The results of a ten-month clinical follow-up indicate a positive outcome.

AIM:To explore the mechanism of BLJZF in the treatment of abnormal lipid metabo-lism based on network pharmacology,molecular docking andin vivo animal experiments.METHODS:TCMSP database,Swiss Target Prediction database,STITCH database and literature search were used to collect and query the chemical composition infor-mation of BLJZF and the corresponding target of drug chemical composition.Disease targets of lipid abnormalities were collected through GeneCards and OMIM databases.Metascape database was used to analyze the gene ontology function and the Kyoto Encyclopedia gene and genome pathway en-richment of common intersection targets.Cyto-scape software was used to construct the correla-tion network diagram of components and targets,so as to select major components and targets for molecular docking study.The hyperlipidemia model was induced by high fat diet,and the control group,model group,positive group and BLJZF group were set up.The serum lipid index contents of triglyceride(TG),total cholesterol(TC),low lipo-protein cholesterol(LDL-C)and high lipoprotein cholesterol(HDL-C)were detected after continuous administration for 4 weeks.The contents of oxida-tive stress index were detected:alanine amino-transferase(ALT)and aspartate aminotransferase(AST).The contents of superoxide dismutase(SOD)and malondialdehyde(MDA)were detected by ELI-SA.Hematoxylin-eosin(HE)staining was used to de-tect the pathological changes of liver tissue.RE-SULTS:A total of 25 components and 315 corre-sponding targets of BLJZF were obtained,1729 tar-gets of lipid abnormalities and 116 common tar-gets of BLJZF,among which the core targets were AKT1,TNF,IL1β,CASP3,etc.GO and KEGG enrich-ment analysis suggested that BLJZF may play a role through the lipid and atherosclerotic pathway,PI3K-Akt,AGE-RAGE in diabetic complications and other signaling pathways.Molecular docking showed that most of the core targets had high binding activity with the active ingredients.Animal experiments showed that compared with model group,TC,TG,LDL-C,ALT,AST and MDA in BLJZF group were sig-nificantly decreased,HDL-C and SOD were signifi-cantly increased,and the degree of liver fat defor-mation was reduced.CONCLUSION:BLJZF has a therapeutic effect on lipid abnormalities.It can treat lipid metabolism abnormalities through multi-component,multi-target and multi-pathway,and provide reference for subsequent drug research on BLJZF.

Post transplantation diabetes mellitus(PTDM)is one of the common complications after kidney transplantation,with an incidence rate of 4%to 30%.The pharmacological treatment of PTDM after kidney transplantation faces many challenges.It is necessary to consider not only the blood glucose-lowering efficacy of the drugs themselves,but also the impact of the drugs on the function of the transplant kidney.At the same time,the interaction between antihyperglycemic drugs and immunosuppressive agents should be taken into account.Glucagon-like peptide-1 receptor agonist(GLP-1RA)have been widely used for blood glucose control in patients with type 2 diabetes mellitus.Some GLP-1RA can also improve the renal and cardiovascular outcomes of patients,and they have multiple metabolic benefits,such as regulating the lipid and reducing body weight.Clinical studies have suggested that GLP-1RA can be used for blood glucose control in kidney transplant recipients with PTDM,with multiple benefits,including reducing the risk of kidney disease and adverse cardiovascular events,as well as improving metabolism.Moreover,no influence of GLP-1RA application on the blood concentration of immunosuppressive agents in kidney transplant recipients with PTDM has been found.Given the good application potential of GLP-1RA in the treatment of kidney transplant recipients with PTDM,this article reviews the current status and future prospects of GLP-1RA treatment for PTDM,analyzes the differences in effects of different GLP-1RA,and explores their potential mechanisms of action in renal protection and multiple metabolic benefits,providing a basis for clinical application.

ObjectiveTo explore the mechanism of Shaoyaotang in the prevention and treatment of colitis-associated carcinogenesis （CAC） based on myeloid-derived suppressor cells （MDSCs）-related immunosuppressive microenvironment. MethodsA total of 140 six-week-old SPF FVB male mice were randomly divided into seven groups： Blank group， Shaoyaotang without model group （7.12 g·kg^-1）， model group， sulfasalazine group （0.52 g·kg^-1）， Shaoyaotang low-dose group （3.56 g·kg^-1）， Shaoyaotang medium-dose group （7.12 g·kg^-1） and Shaoyaotang high-dose group （14.24 g·kg^-1）， with 20 mice in each group. The blank control group and the Shaoyaotang without model group received a single intraperitoneal injection of physiological saline （10 mg·kg^-1）， while the other five groups were given a single intraperitoneal injection of azoxymethane （AOM） （10 mg·kg^-1）. After 1 week， the mice were given drinking water containing 2% dextran sulfate sodium （DSS） for 1 week， followed by normal drinking water for 2 weeks. This cycle was repeated three times over a total period of 14 weeks to establish the CAC mouse model. Each group was administered gavage once daily for 2 weeks starting on the 14^th day of the experiment， followed by three times a week until the end of the experiment. The body weight of the mice was recorded weekly. Mice were sacrificed on the 28^th and 98^th days of the experiment. After dissection， the colon length， colon weight， spleen weight， tumor size， and tumor number were measured. Hematoxylin and eosin （HE） staining was used to assess the pathological morphology of colon tumor tissue. Flow cytometry was used to detect MDSCs， regulatory T cells （Tregs）， CD4⁺ T cells， CD8⁺ T cells， and the CD4⁺/CD8⁺ T cell ratio in the spleen. Immunohistochemistry was used to detect the expression levels of programmed cell death protein-1 （PD-1）， programmed cell death ligand 1 （PD-L1）， phosphorylated AMP-activated protein kinase （p-AMPK）， phosphorylated nuclear factor-κB （p-NF-κB）， and hypoxia-inducible factor 1α （HIF-1α） in the colon tissue. ResultsOn day 14， compared with the blank group， the body weight of the model group was significantly reduced （P<0.01）， reaching its lowest point on day 28 （23.39 ± 0.95 ） g. On days 28 and 98， compared with the blank group， the colon length in the model group was significantly shortened （P<0.01）， the colon index significantly increased （P<0.01）， the spleen index significantly increased （P<0.01）， and the tumor load significantly increased （P<0.01）. HE staining showed that in the model group， tumor cells， a large number of inflammatory cell infiltrates， goblet cell disappearance， and crypt loss were observed. In each dose group of Shaoyaotang， the damage to the colonic mucosa， inflammatory cell infiltration， and crypt structure destruction were alleviated. Compared with the model group， the body weight of mice in each dose group of Shaoyaotang increased. On day 98， the colon length was significantly increased （P<0.01）， the colon index significantly decreased （P<0.01）， the spleen index significantly decreased （P<0.01）， and the tumor burden significantly decreased （P<0.01） in each Shaoyaotang dose group. On days 28 and 98， MDSCs and Tregs in the spleen of the medium- and high-dose Shaoyaotang groups were significantly reduced （P<0.01）， while CD4⁺ T cells and the CD4⁺/CD8⁺ T cell ratio were significantly increased （P<0.01）. The proportion of CD8⁺ T cells in the spleen and the expression levels of PD-1 and PD-L1 in the colon tissues of mice in each Shaoyaotang dose group were significantly increased to varying degrees （P<0.05， P<0.01）. On days 28 and 98， the expression of p-AMPK-positive cells in the colon tissue of the medium- and high-dose Shaoyaotang groups was significantly increased （P<0.01）， while the expression of p-NF-κB and HIF-1α was significantly reduced （P<0.01）. ConclusionShaoyaotang can regulate MDSC recruitment and modulate the immune function of T lymphocyte subsets to inhibit the occurrence and development of AOM/DSS-induced CAC in mice. The mechanism may be related to the activation of the AMPK/NF-κB/HIF-1α pathway.

Tumor immune homeostasis is a dynamic equilibrium state in which the body removes abnormal mutated cells in time to prevent tumor development without damaging other normal cells under the surveillance of the immune system. It is an important concept to understand the process of tumor development. Programmed cell death （PCD） is a kind of regulable cell death including various forms such as apoptosis， autophagy， pyroptosis， necrosis， and ferroptosis. It is regarded as an important way for the body to remove abnormal or mutated cells. In recent years， modern research has found that PCD has a bi-directional regulatory effect on carcinogenesis and tumor development. In the early stage of tumor formation， PCD can control tumor development in time by playing a specific immune clearance role， while in the later tumorigenic stage， PCD can promote the growth and development of tumor cells by forming a tumor-specific microenvironment， resulting in carcinogenic effects. Therefore， PCD is regarded as an important way to maintain tumor immune homeostasis. Based on the idea of ''supporting the vital Qi and cultivating the root'' by professors Yu Guiqing and Piao Bingkui， the team proposed the theory of ''regulating Qi and resolving toxins'' and applied it to clinical tumor prevention and treatment. Based on the theory of ''regulating Qi and resolving toxins''， the research summarized the current progress of modern medical research on mechanisms related to PCD to explore the role of PCD in the regulation of tumor immune homeostasis. The article believed that the harmonious state of Qi movement was the basic condition for normal PCD to maintain tumor immune homeostasis， while the disorder of Qi movement and the evolution of tumor toxicity were the core processes of abnormal PCD and disorder of tumor immunity homeostasis， which led to the escape and development of tumor cells. Therefore， under the guidance of ''regulating Qi and removing toxins''， the idea of full-cycle prevention and treatment of tumors was proposed summarily. In the early stage of tumor formation， the method of ''regulating Qi movement and strengthening vital Qi'' was applied to reestablish tumor immune homeostasis and to promote the elimination of abnormal cells. In the late tumorigenic stage， the method of ''resolving toxins and dispelling evils'' was applied to reverse the specific microenvironment of tumors and inhibit the development of tumor cells， with a view to providing new theoretical support for the prevention and treatment of tumors through traditional Chinese medicine.

Objective:To analyze the guiding value of index of consciousness 1(IoC1) and index of consciousness 2(IoC2) in anesthesia management of laparoscopic surgery.Methods:A total of 100 elderly patients undergoing laparoscopic surgery under general anesthesia in the Beijing Coal Group General Hospital from June 2022 to October 2023 were prospectively selected as research objects, and they were divided into the observation group and the control group according to random number table method, with 50 cases in each group. The observation group used IoC1 and IoC2 to monitor and guide anesthesia management, while the control group used bispectral index (BIS) to monitor the depth of anesthesia, and combined with the experience of anesthesiologists to guide anesthesia management. The changes of vital signs of patients in the two groups were compared after calm entry (T 0), induction of anesthesia (T 1), implantation of laryngeal mask 1 min (T 2), carbon dioxide (CO 2) pneumoperitoneum 1 min (T 3), and removal of laryngeal mask 1 min (T 4). The time of resuscitation extubation, dosage of anesthetic drugs, dosage of vasoactive drugs, IoC1, IoC2 and BIS were compared between the two groups. Results:The pneumoperitoneum time and incidence of circulatory instability between the two groups had no statistical differences ( P>0.05). The time of resuscitation and extubation in the observation group was shorter than that in the control group : (8.16 ± 6.08) min vs. (13.10 ± 7.09) min, the dosage of propofol and remifentanil were lower than those in the control group : (382.10 ± 201.90) mg vs. (465.48 ± 213.51) mg, (0.81 ± 0.62) mg vs. (1.17 ± 0.55) mg, there were statistical differences ( P<0.05). The amount of ephedrine and atropine between the two groups had no statistical differences ( P>0.05). The dosage of norepinephrine in the observation group was lower than that in the control group: (106.42 ± 46.12) μg vs. (147.04 ± 51.38) μg, there was statistical difference ( P<0.05). The heart rate, mean arterial pressure (MAP) and IoC1/BIS between the two groups had no statistical differences ( P>0.05). The IoC2 values of T 0, T 1, T 2, T 3 and T 4 in the observation group were 97.46 ± 2.46, 45.28 ± 5.08, 48.64 ± 4.51, 50.44 ± 4.21 and 96.08 ± 2.69, respectively. The IoC2 value of T 3 was higher than that of T 1 and T 2 in the observation group, there were statistical differences ( P<0.05). Conclusions:The application of IoC1 and IoC2 to monitor and guide the anesthesia management of laparoscopic patients under general anesthesia makes the application of anesthetic drugs more quantitative and precise, the perioperative vital signs more stable, and the recovery time faster.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.
