Liver cancer is one of the most common malignant tumors in the digestive system and ranks sixth among newly diagnosed malignant tumors worldwide. Transforming growth factor-β （TGF-β） regulates cell differentiation， proliferation， apoptosis， and other physiological and pathological mechanisms and exerts cancer-suppressive and pro-cancerous dual effects in the process of tumor development. In recent years， with the continuous exploration of the mechanism of liver cancer， it has been found that the conversion of the cancer-suppressive effect into a pro-cancerous effect of this pathway plays a key role in the development of liver cancer. Traditional Chinese medicine （TCM） provides a unique perspective for the classification， diagnosis， and treatment of liver cancer with its comprehensive regulatory effects of multi-components， multi-targets， and multi-pathways. This paper summarized that the cancer-suppressive mechanisms of the TGF-β signaling pathway included promoting cancer cell cycle arrest， apoptosis， autophagy， et al， while the pro-cancerous mechanisms included promoting cancer cell proliferation， invasion and metastasis， immunosuppression， angiogenesis， et al. The TCM compounds intervening this pathway were sorted out， including Jianpi Huayu compound， Fuyang Baoyuan compound， Yipi Yanggan compound， Fuzheng Jiedu compound， compound Astragalus and Salvia， Biejia Jianwan， Dahuang Zhechong pill， and Qingxiang powder. The single TCMs mainly included Schizocapsa plantaginea， Dendrobii Caulis， Gleditsia sinensis， and Dracaena cochinchinensis. The active ingredients of TCM are mainly concentrated on flavonoids， alkaloids， glycosides， phenolics， terpenoids， polysaccharides， and other kinds of compounds. At the same time， it summarized that the liver cancer inhibition mechanism of TCM by regulating this pathway mainly included promoting apoptosis of liver cancer cells， blocking the cell cycle， and inhibiting liver cancer cell proliferation， migration， invasion， angiogenesis， immune escape， etc. The mechanism aims to give full play to the advantages of TCM and precisely regulate the TGF-β signal， thereby exerting positive anti-tumor effects， opening up a new direction for the precise targeted treatment of liver cancer， and providing a scientific basis and a new strategy for the application of TCM in the treatment of liver cancer.

Hepatocellular carcinoma（HCC）， as one of the common malignant tumours， has seen a continuous rise in incidence and mortality worldwide， posing a serious threat to human health. However， traditional treatments have certain limitations， therefore， the exploration of new therapeutic strategies is particularly urgent. In recent years， with in-depth research on the regulatory mechanisms of microRNA（miRNA） in tumour occurrence and development， it has become new targets for HCC diagnosis and treatment. As a traditional treatment method， Chinese medicine， due to its multi-component， multi-pathway， and multi-target overall regulatory characteristics， shows broad prospects in treating HCC by regulating miRNAs. Accordingly， this paper reviews recent studies on the role of miRNAs in HCC and research advances in traditional Chinese medicine interventions， finding that various miRNAs play key roles in HCC cell cycle regulation， proliferation and apoptosis， invasion and metastasis， immune microenvironment， and drug resistance. It summarises how active ingredients， extracts， medicinal pairs， and formulas of Chinese medicine act on specific miRNAs to regulate their downstream target gene expression， affecting the malignant behaviour of HCC cells and exerting anti-cancer effects. This study aims to provide a theoretical basis for miRNAs as potential biomarkers and therapeutic targets for HCC， as well as to offer new ideas for developing miRNA-based targeted Chinese medicine therapies.

ObjectiveTo explore the effects of Jingui Shenqiwan （JSW） and Liuwei Dihuangwan （LDW） on the reproductive ability and brain function of normal mice and compare the actions of the two medications. MethodsSeven groups of female and male mice were divided at a ratio of 2∶1. Except for the control group， the other six groups were as follows： a group of both males and females receiving JSW （3.0 g·kg^-1）， a group of both males and females receiving LDW （4.5 g·kg^-1）， a group of males receiving water and females receiving JSW， a group of males receiving water while females receiving LDW， a group of females receiving water while males receiving JSW， and a group of females receiving water while males receiving LDW. Each group was administered the drug for 14 days and then caged together at a 2∶1 （female∶male） ratio to detect the number of pregnant mice and calculate the pregnancy rate. Pregnant mice continued receiving the drug until they naturally gave birth， which was followed by the observation of newborn mice， calculation of their average number， and the measurement of the offspring's preference for sugar water and neonatal recognition index. At the end of the experiment， the weights of the thymus and spleen were measured to calculate the organ coefficients， and mRNA or protein expression was analyzed in the brain and testes or ovaries. A 1% sucrose solution was used to examine the euphoria of their brain reward systems， while novel object recognition test （NOR） was applied to assess their memory capabilities. mRNA expression was detected using real-time quantitative polymerase chain reaction （Real-time PCR） assay， and protein expression was analyzed with Western blot. ResultsCompared with the control group， oral administration of JSW to both male and female mice for 14 days significantly increased the pregnancy rate of female mice on day 2 after being caged together （P<0.05）， while LDW showed a trend but no statistical significance. Additionally， compared with the control group， JSW could upregulate the gene expression of gonadotropin-releasing hormone （GnRH） in the thalamus， as well as reproductive stem cell factor （SCF） and tyrosine kinase receptor （c-Kit） in the testes and reproductive stem cell marker mouse vasa homologue （MVH） in the ovaries， upregulate the expression of proteins influencing neuronal functional activity， such as brain-derived neurotrophic factor （BDNF）， in hippocampal neurons （P<0.05）， and enhance sucrose preference in male mice （P<0.05）. Compared with the control group， JSW significantly increased sucrose preference and novel object recognition index in offspring mice （P<0.05）， which was related to the upregulation of hippocampal dopamine D1 receptor （D1R） and N-methyl-D-aspartate receptor （Nmdar） gene expression. Compared with the control group， both JSW and LDW could upregulate the protein expression of glucocorticoid receptor （GR）， BDNF， and tyrosine kinase receptor B （TrkB） in the hippocampus of offspring mice （P<0.05）. ConclusionJSW significantly enhances the reproductive ability of normal mice， which is not only related to the release of gonadotropin but also associated with its regulation of brain function. Additionally， JSW has a certain regulatory effect on the brain function of the offspring mice.

Objective: To characterize perioperative dynamic changes in immune-cell phenotypes and inflammatory cytokines in patients undergoing CPB (cardiopulmonary bypass) cardiac surgery, and to explore their associations with postoperative outcomes. Methods: In this prospective cohort study, 120 adult patients who underwent elective cardiac surgery under CPB at West China Hospital from May 2022 to March 2023 were enrolled. Perioperative immune-cell phenotypes and concentrations of 40 inflammation-related cytokines were measured. The primary outcomes were the sequential organ failure assessment (SOFA) score at 24 h after surgery and ΔSOFA (the peak SOFA score within 48 h after surgery minus the preoperative SOFA score). Secondary outcomes included major adverse cardiovascular events (MACE), acute kidney injury (AKI), respiratory failure, severe liver injury, and infection. Results: The mean age of enrolled patients was 57±10 years. Of these, 52% (62/120) were male and 90% (108/120) underwent valve surgery. During the rewarming to the end of CPB, neutrophil counts rapidly increased (7.39×10 /L vs preoperative 3.07×10 /L, P<0.001), with significant upregulation of CD11b (7.30×10 /L vs preoperative 3.05×10 /L, P<0.001) and CD54 (7.15×10 /L vs preoperative 2.99×10 /L, P<0.001). Lymphocyte counts increased at the end of CPB (1.75×10 /L vs preoperative 1.12×10 /L, P<0.001) but decreased significantly at 24 h after surgery (0.59×10 /L vs preoperative 1.12×10 /L, P<0.001). Plasma analysis showed that multiple pro-inflammatory cytokines increased during CPB and remained elevated up to 24 h after surgery; five chemokines and the anti-inflammatory cytokine IL-10 peaked at the end of CPB. The SOFA score increased from 1 (1, 2) preoperatively to 7 (5, 10) at 24 h after surgery, with a ΔSOFA of 6 (4, 8). Within 30 days after surgery, 48 patients (40.0%) developed AKI, 17 (14.2%) developed infection, 4 (3.3%) developed severe liver injury, 3 (2.5%) developed respiratory failure, and 3 (2.5%) experienced MACE. During the 2-year follow-up, 8 patients (6.7%) experienced MACE and 5 (4.2%) died. Conclusion: Multi-organ dysfunction is common after cardiac surgery under CPB (median ΔSOFA, 6), accompanied by perioperative activation of multiple immune-cell subsets and upregulation of pro-inflammatory, anti-inflammatory, and chemotactic mediators. This study provides data-driven evidence and research clues for further investigation of the associations between CPB-related immune perturbations and postoperative organ dysfunction and clinical outcomes.

ObjectiveTo conduct an epidemiological investigation and analysis of a clustered scabies outbreak in a middle school, so as to provide evidence for developing targeted prevention and control strategies. MethodsCase data on a clustered scabies outbreak occurring in a middle school of Shaanxi Province in 2025 were collected. Field epidemiological approaches were adopted to define cases, search for infected individuals, and describe the temporal, spatial, and population distribution. Specimens were collected from individuals and surrounding environments for laboratory testing. ResultsA total of 25 scabies cases were identified in 4 classes and 9 dormitories of the school. All cases were first-year high school students. The overall attack rate was 6.00% (25/414); the attack rate was 10.53% (22/209) among male students and 1.46% (3/205) among female students. The disease course ranged from 10 to 30 days, with a median duration of 14 days, and 3 students (12.00%) continued attending classes with ongoing infection. Skin scrapings collected from lesion sites of 3 patients were examined under microscopy, all of which were positive for Sarcoptes scabiei; no laboratory testing was performed for the remaining cases. This clustered scabies infection outbreak lasted for one month. All affected students recovered completely without severe complications or deaths, and the outbreak was effectively contained. ConclusionThis scabies infection is a clustered school-based scabies outbreak caused by Sarcoptes scabiei. Affected patients present relatively severe symptoms and a prolonged disease course. Scientific and standardized preventive systems should be established to enable timely early warning and emergency response.

OBJECTIVE To investigate the effects of dexborneol on the pharmacokinetic parameters of edaravone in rats under the pathological condition of cerebral ischemic stroke （CIS）.METHODS Twenty male SD rats were randomly divided into the edaravone group and the Edaravone and dexborneol concentrated solution for injection （EDB injection） group， with 10 rats in each group. A middle cerebral artery occlusion （MCAO） rat model was established using the modified Longa suture method. Within 5 min of ischemia-reperfusion， the corresponding drug solutions were injected via the tail vein at a dose of 2.5 mg/kg （calculated by edaravone）. Blood samples were collected from the orbital venous plexus at 0.08， 0.5， 1， 3， 6， 18， and 24 h after injection. With carbamazepine as the internal standard， the plasma concentration of edaravone was determined by ultra-performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS） method. Pharmacokinetic parameters were calculated using DAS software and compared between the two groups.RESULTS Compared with the edaravone group， the peak concentration （ c max ） of edaravone in the EDB injection group was significantly increased （ P ＜0.05）， while no statistically significant differences were observed in the half life， time to peak， clearance， or area under curve （ P ＞0.05）.CONCLUSIONS Under the pathological condition of CIS， dexborneol can increase the c max of edaravone in the plasma of model rats， but has no significant effect on the systemic exposure or clearance of edaravone.

The development of polysaccharide conjugate vaccines, which convert polysaccharide antigens into T-cell-dependent immunogens through covalent conjugation with protein carriers, represents a critical strategy for enhancing immune protection in infants and young children. Globally licensed conjugate vaccines currently employ carrier proteins including Tetanus Toxoid, Diphtheria Toxoid, and Cross-Reacting Material 197. Recent advances have focused on three key areas: novel carrier protein discovery, optimized conjugation strategies, and evaluation of immune interference during co-administration of multivalent formulations. These efforts aim to achieve broader serotype coverage, prolonged protective efficacy, and simplified immunization schedules. This review synthesizes recent progress in carrier protein development, encompassing vaccine design principles, manufacturing processes, safety profiles, and epidemiological effectiveness. Furthermore, it critically examines current selection criteria for carrier proteins, their clinical applications, and persistent challenges, providing strategic insights to inform future conjugate vaccine development and immunization policy optimization in China.

AIM To investigate the effect of Tongmai Kaiqiao Pills on angiogenesis and JAK2/STAT3/VEGF signaling pathway in rats with vascular cognitive impairment(VCI).METHODS Ten of seventy-two male SD rats were randomly selected as sham operation group,and the remaining rats were made VCI rat model by ligation of common carotid artery in stages.Rats after successful modeling were randomly divided into model group,low and high dose groups of Tongmai Kaiqiao Pills(13.8 g/kg,27.6 g/kg),nimodipine group(10 mg/kg)and high dose of Tongmai Kaiqiao Pills+AG490(JAK2 inhibitor)group(Tongmai Kaiqiao Pills 27.6 g/kg+AG490 3 mg/kg).The samples were taken after 4 weeks of corresponding dose of drugs.Pathological changes in hippocampus were observed by HE staining.Nissl staining was used to observe the loss of neurons in hippocampus.Western blot was used to detect the protein expressions of p-JAK2,p-STAT3 and VEGF in hippocampus.The ultrastructure of neurons in hippocampus was observed by transmission electron microscope.The expression of CD34 was detected by immunofluorescence staining and the microvessel density(MVD)of ischemic penumbra was calculated.RESULTS Compared with the sham operation group,the escape latency of the model group was prolonged(P＜0.01),and the times of crossing the platform were reduced(P＜0.01);neurons in hippocampus were loose in structure and disordered in arrangement;the number of Nissl bodies decreased and the loss was serious;mitochondrial crista dissolved and disappeared,and mitochondrial damage was aggravated;the protein expressions of p-JAK2,p-STAT3 and VEGF in hippocampus increased(P＜0.05);the number of MVD in hippocampus increased(P＜0.01).Compared with the model group,the escape latency of rats in each dose group of Tongmai Kaiqiao Pills and nimodipine group were shortened(P＜0.01),and the times of crossing the platform were increased(P＜0.01);the number of hippocampal neurons increased,the morphology was normal,and the disorder degree improved;Nissl's corpuscles were abundant and the loss is reduced;mitochondrial damage was reduced and gradually returned to normal shape;the protein expressions of p-JAK2,p-STAT3 and VEGF in hippocampus increased(P＜0.05,P＜0.01);the number of MVD in hippocampus increased(P＜0.05,P＜0.01).AG490 reversed the high-dose effect of Tongmai Kaiqiao Pills(P＜0.05,P＜0.01).CONCLUSION Tongmai Kaiqiao Pills may promote angiogenesis,reduce neuronal damage and promote the recovery of brain function by activating JAK2/STAT3/VEGF signaling pathway,thus playing an improving role in VCI rats.

By using a strategy of leveraging the ability of metal-organic frameworks(MOFs)materials to precisely regulate the spatial orientation of cyclodextrins(CD),a polystyrene-modified γ-cyclodextrin metal-organic frameworks(PS-CD-MOFs)capillary coating was established and applied to the chiral separation of amino acids in open-tubular capillary electrochromatography(OT-CEC)based on the excellent film-forming property of polystyrene(PS).Characterization results by Fourier transform infrared spectroscopy(FT-IR),X-ray diffraction(XRD)indicated that PS was successfully grafted onto the surface of CD-MOFs.The modification significantly improved the structural stability and thermal stability of CD-MOFs while maintaining the integrity of the MOFs.The PS-CD-MOFs coated capillary electrophoresis system exhibited excellent performance in separating dansylated amino acid enantiomers(Dns-D,L-AAs).Specifically,under the optimal separation conditions(Sodium dodecyl sulfate/boric acid buffer system,20 cm capillary,and 10 kV effective voltage),good separation was achieved for D,L-methionine(D,L-Met)and D,L-serine(D,L-Ser).Further quantitative analysis showed that Dns-D,L-Met presented a good linear relationship in the concentration range of 10.0-1500.0 μmol/L,with a correlation coefficient close to 0.998,demonstrating high sensitivity and repeatability.Not only did it overcome the problem that traditional CD(used as additives in capillary electrophoresis)could not precisely control the spatial orientation of chiral resolvents,but also it solved the issues of insufficient stability and bonding amount of CD-MOFs coatings by utilizing the excellent film-forming property of polymers on the inner wall of capillaries.This study provided an efficient and controllable new strategy for construction of chiral separation stationary phases.
