ObjectiveTo investigate the clinical application value of thromboelastographic parameters in assessing coagulation function by analyzing the thromboelastographic features of patients with primary liver cancer （PLC）， and to provide a basis for coagulation management and prognostic evaluation in liver cancer patients. MethodsA retrospective analysis was performed for 1 253 PLC patients who were admitted to The First Affiliated Hospital of Xi’an Jiaotong University from May 2015 to December 2022. According to the presence or absence of cirrhosis， the patients were divided into non-cirrhosis group with 262 patients and cirrhosis group with 991 patients， and according to the presence or absence of HBV infection， they were divided into HBV infection group with 1 055 patients and non-HBV infection group with 198 patients. The patients were stratified based on the severity of liver cirrhosis （Child-Pugh class and MELD score） and liver reserve function （indocyanine green retention rate at 15 minutes ［ICGR15］）， and thromboelastography was used to measure thromboelastographic parameters （reaction time ［R］， coagulation formation time ［K］， α-angle， maximum thrombosis amplitude ［MA］， and coagulation composite index ［CI］） and conventional coagulation markers. The t-test was used for comparison of normally distributed continuous data between two groups； a one-way analysis of variance was used for comparison between multiple groups， and the least significant difference t-test was used for further comparison between two groups. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the Kruskal-Wallis H test was used for comparison between multiple groups， and the Bonferroni correction method was used for further comparison between two groups. The chi-square test was used for comparison of categorical data between grouips， and the Spearman test was used for correlation analysis. ResultsAmong the 991 patients in the cirrhosis group， 826 had Child-Pugh class A （5 — 6 points）， and 165 had Child-Pugh class B （7 — 9 points）； 812 had an MELD score of <10， and 179 had an MELD score of ≥10； 679 had an ICGR15 of <10%， and 294 had an ICGR15 of ≥10%. Compared with the patients with Child-Pugh class A， the patients with Child-Pugh class B had a significantly longer K time and significant reductions in α-angle， MA， and CI （all P <0.001）； compared with the MELD score <10 group， the MELD score ≥10 group had a significantly longer K time and significant reductions in α-angle， MA， and CI （all P<0.001）； compared with the ICGR15 <10% group， the ICGR15 ≥10% group had a significantly longer K time and a significant reduction in MA （both P <0.001）. Among the 1 253 patients， MA was strongly positively correlated with fibrinogen and platelet count （r=0.675 and 0.667， both P<0.001）； The MA had a weak correlation with Child-Pugh score， MELD score， and ICGR15 （r=-0.112， -0.250， and -0.117， all P<0.001）， while the K time，α-angle and CI were weakly correlated with the MELD score （r=0.222， -0.184， and -0.183， all P<0.001），R time was negatively correlated with ICGR15 （r=-0.080， P=0.005）. The HBV infection group had significantly higher MA and CI than the non-HBV infection group （P<0.05）. ConclusionThromboelastography can sensitively identify the hypocoagulable state associated with the progression of liver cirrhosis and the hypercoagulable tendency in HBV-related liver cancer， which provides an important reference for individualized anticoagulant therapy in clinical practice.

Liver diseases have become a major challenge threating the global health, posing a heavy burden on both social and personal well-being. In recent years, the development of the gut-liver axis theory has provided new research perspectives and intervention strategies for the prevention and treatment of liver diseases. Natural products, recognized as biological molecules with diverse sources, rich activities, and minimal side effects, demonstrate great potential in regulating intestinal flora and improving liver health. Studies have shown that natural products such as saponins, polyphenols, polysaccharides, and alkaloids can regulate the composition and metabolites of intestinal flora, thereby intervening in liver diseases. In this paper, we systematically review the role of natural products in the regulation of the intestinal flora-gut-liver axis and summarize recent research progress in the prevention and treatment of liver diseases. Furthermore, we outline the challenges and limitations currently facing the study in this field. Finally, this paper makes an outlook on the clinical application of natural products in treating liver diseases and discusses future research directions, aiming to give new insights into the mechanisms by which natural products regulate the intestinal flora-gut-liver axis and the applications of these products in the prevention and treatment of liver diseases.

ObjectiveTo determine the prevalence and determinants of Mycobacterium tuberculosis latent infection among primary and secondary school students in Cixi City, Zhejiang Province, so as to provide references for the prevention and control of tuberculosis in school settings. MethodsInterferon-γ release assay (IGRA) testing was performed to fourth-grade primary school students , as well as to those grade 7 and grade 10 students of the academic year 2024‒2025 in Cixi City. Individuals tested positive for IGRA were subsequently subjected to chest X-ray examination and sputum tests (including three smear microscopy examinations and one mycobaterial culture), and epidemiological investigations were carried out for confirmed cases. Infection rates were compared across student categories by χ² tests, while factors influencing infection were analysed through multivariate logistic regression. ResultsA total of 36 214 students completed tuberculosis screening, with an infection rate of 0.72% (260/36 214). The tuberculosis infection rates among fourth-grade primary school students, non boarding grade 7 students, boarding grade 7 students, grade 10 students of senior high school and of vocational high school were 0.68% (89/13 139), 0.75% (86/11 501), 0.51% (13/2 553), 0.76% (52/6 819), and 0.91% (20/2 202), respectively. Multivariate logistic regression analyses indicated that students with a history of close contact with tuberculosis patients (OR=21.435, P<0.001) had a higher risk of tuberculosis infection, students with a geographic origin outside Zhejiang Province (OR=1.485, P=0.002) had a higher risk of infection than those within Zhejiang Province. Furthermore, students from ethnic minority classes (OR=4.232, P<0.001) might be high-risk groups for tuberculosis infection in high school settings. One IGRA-positive student was confirmed as bacteriologically positive pulmonary tuberculosis by liquid culture of sputum collected one month later. ConclusionSchools should prioritize tuberculosis screening. Students with a history of close contact, those with a geographic origin outside Zhejiang Province, and those enrolled in minority classes should be taken as priority targets for future tuberculosis screening programmes. A tracking and follow-up system must be established for IGRA-positive students to prevent persistent transmission of Mycobacterium tuberculosis within the school settings.

Diabetic kidney disease(DKD)is a severe complication of diabetes.Its incidence increases annually,posing a significant burden on public health.The strategy of symptomatic treatment based on pathogenesis differentiation,focusing on identifying pathogenesis,is particularly meaningful for managing complex and variable chronic diseases like DKD.Within this framework,the state of latent heat persists throughout DKD,with"latent heat causing accumulation"identified as the core pathogenesis affecting and promoting the development and progression of DKD.This paper is centered on the concept of"latent heat causing accumulation"and adopts symptomatic treatment based on pathogenesis differentiation as its guiding principle to explore the role of latent heat in DKD.It highlights that the onset of DKD involves environmental and constitutional pathogenesis associated with"the concealment of latent heat"and"stagnant-heat invading collaterals"as the initial pathogenesis,"latent heat causing accumulation"as the core mechanism,and"secondary turbid heat"as the derivative pathogenesis.These pathogenesis factors collectively influence the symptoms,sequelae,and prognosis of DKD.Moreover,this paper provides commonly used prescriptions for different stages,syndrome types,and complications of the disease,aiming to offer a reference for clinical practice in flexibly addressing changes in disease conditions based on varied pathogenesis.

Chloride voltage-gated channel, as an important ion channel in living organisms, has many important physiological functions.The gene encoding chloride voltage-gated channel protein is CLCN, which has nine members(CLCN1~7, CLCNKa, and CLCNKb).The CLCN gene variants lead to abnormal expression of chloride channel proteins, which affect the biological activities of neuronal signaling, ion homeostasis, intracellular transport, and lysosomal protein degradation, thereby altering ion channel gating properties, interfering with the normal developmental process of the nervous system, and causing the development of intellectual disability.In recent years, further studies of the CLCN gene have found that the variants in some members of this family are closely related to intellectual disability.This review will discuss the correlation between the chloride voltage-gated channel and intellectual disability.

ObjectiveTo evaluate the clinical efficacy of Qimai Qinlou prescription in the treatment of elderly community-acquired pneumonia （CAP） （non-severe） with Qi and Yin deficiency and phlegm-heat obstructing lung syndrome and its impact on immune-inflammatory factors. MethodA total of 120 eligible patients were randomly divided into an observation group （60 cases） and a control group （60 cases）. Both groups received intravenous cefoxitin sodium. In addition， the observation group received oral Qimai Qinlou prescription， while the control group received an oral placebo simulating Qimai Qinlou prescription. The treatment course was 14 days. The disappearance time of major clinical symptoms and signs was recorded. Traditional Chinese medicine （TCM） syndrome scores and the Clinical Research Outcome （CAP-CRO） scale scores for pneumonia of the two groups were compared. Chest computed tomography （CT） scans were performed， and peripheral blood levels of procalcitonin （PCT）， interleukin-6 （IL-6）， serum amyloid A （SAA）， high-sensitivity C-reactive protein （hs-CRP）， CD4⁺， CD8⁺， and CD4⁺/CD8⁺ were measured. The conversion rate to severe condition during hospitalization， readmission rate within 30 days after discharge， and safety evaluation were recorded. ResultAfter treatment， the observation group showed significantly shorter time of fever， cough， expectoration， and disappearance time of lung moist rales than the control group （P<0.01）. The TCM syndrome scores， CAP-CRO scores in all dimensions， and total scores in both groups were significantly reduced as compared with those before treatment （P<0.01）. After treatment， the observation group had a more significant reduction than the control group （P<0.01）. The levels of PCT， IL-6， SAA， and hs-CRP in both groups were significantly reduced as compared with those before treatment （P<0.01）. After treatment， the observation group showed a more significant reduction than the control group （P<0.01）. There was no statistically significant difference in the changes of CD4⁺， CD8⁺， and CD4⁺/CD8⁺ in the control group before and after treatment. However， in the observation group， CD4⁺ and CD4⁺/CD8⁺ levels significantly increased （P<0.01）， while CD8⁺ level significantly decreased （P<0.01） after treatment. After treatment， CD4⁺ and CD4⁺/CD8⁺ in the observation group significantly increased （P<0.01）， and CD8⁺ significantly decreased as compared with those in the control group （P<0.01）. At 7， 10， and 14 days after treatment， the curative rates in the observation group were 53.33% （32/60）， 85.00% （51/60）， and 91.67% （55/60）， respectively， which were higher than 31.67% （19/60）， 61.67% （37/60）， and 68.33% （41/60） in the control group （χ²=5.763， 8.352， 10.208， P<0.05）. After treatment， the total effective rate of CT scanning in the observation group was 93.33% （56/60）， higher than 80.00% （48/60） in the control group （χ²=4.615， P<0.05）. The conversion rate to severe condition during hospitalization in the observation group was 3.33% （2/60）， lower than 15.00% （9/60） in the control group （χ²=4.904， P<0.05）. The readmission rate within 30 days after discharge in the observation group was 8.33% （5/60）， lower than 23.33% （14/60） in the control group （χ²=5.065， P<0.05）. No serious adverse drug reactions were observed in either group during the treatment period. ConclusionQimai Qinlou prescription can enhance immune function， alleviate inflammatory reactions， significantly relieve clinical symptoms， shorten the duration of the disease， improve the curative rate and CT scanning efficacy， prevent disease progression， reduce the readmission rate in the short term， and is clinically safe for the treatment of elderly patients with non-severe CAP with Qi and Yin deficiency and phlegm-heat obstructing lung syndrome. It is worthy of further research and application.

ObjectiveTo study the protective effect of Shoutaiwan-containing serum on the human chorionic trophoblast cells （HTR-8/Svneo） exposed to hydrogen peroxide （H₂O₂） via the nuclear factor erythroid 2-related factor 2 （Nrf2） signaling pathway and to decipher the underlying mechanism. MethodThe H₂O₂ solutions of 25， 50， 100， 200， 400 μmol·L^-1 were used to treated the HTR-8/Svneo cells. The cell counting kit-8 （CCK-8） was employed to measure the proliferation of the cells and further determine the optimal concentration of H₂O₂ solution for modeling and the drug-containing serum. The cells were divided into a blank group， a model group， a dydrogesterone group， and a Shoutaiwan group. The effect of drug-containing serum on H₂O₂-induced proliferation of HTR-8/Svneo cells was detected by CCK-8 assay. The intracellular reactive oxygen species （ROS） in each group was determined by enzyme-linked immunosorbent assay （ELISA）. Western blot was employed to determine the protein levels of Nrf2， heme oxygenase-1 （HO-1）， quinone oxidoreductase 1 （NQO1）， cysteine-containing aspartate-specific protease-3 （Caspase-3）， and B cell lymphoma/leukemia-2 （Bcl-2）. Cellular immunofluorescence was employed to detect the expression of Nrf2 and Bcl-2. Real-time quantitative polymerase chain reaction （Real-time PCR） was carried out to examine the mRNA level of Nrf2， Caspase-3， and Bcl-2 associated X protein （Bax）. ResultThe optimal concentration of H₂O₂ for modeling was 50 μmol·L^-1， and the optimal concentration of drug-containing serum was 10%. Compared with the blank group， the modeling decreased the proliferation of cells （P<0.01）， increased the intracellular ROS （P<0.01）， down-regulated the protein levels of Nrf2， HO-1， NQO1， and Bcl-2 （P<0.05， P<0.01）， up-regulated the protein levels of Caspase-3 and Bax （P<0.01）， down-regulated the mRNA level of Nrf2 （P<0.01）， and up-regulated the mRNA levels of Caspase-3 and Bax （P<0.05， P<0.01）. Compared with the model group， Shoutaiwan-containing serum increased the proliferation of cells （P<0.01）， reduced the intracellular ROS （P<0.01）， up-regulated the protein levels of Nrf2， HO-1， NQO1， and Bcl-2 （P<0.01）， down-regulated the protein levels of Caspase-3 and Bax （P<0.05， P<0.01）， up-regulated the mRNA level of Nrf2 （P<0.05）， and down-regulated the mRNA levels of Caspase-3 and Bax （P<0.05， P<0.01）. ConclusionShoutaiwan-containing serum can inhibit H₂O₂-induced apoptosis by activating the Nrf2 signaling pathway and has protective effect on human chorionic trophoblast cells.

ObjectiveTo observe the effect of Zhuluan decoction on the ovarian reserve function of rats with cyclophosphamide-induced premature ovarian insufficiency， and explore the protective mechanism of Zhuluan decoction in the rat model of premature ovarian insufficiency based on the phosphatidylinositol-3-kinases/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway. MethodSixty female SD rats were randomly divided into normal group （n=10） and model group （n=50）. The model group was given intraperitoneal injection of cyclophosphamide （50 mg·kg^-1 loading dose on the 1^st day+8 mg·kg^-1 low-dose maintenance on the 2^nd–15^th days）. After successfully modeling， the rats were randomly divided into model group， positive drug （progynova） group （0.1 mg·kg^-1·d^-1）， and low-， medium-， and high-dose Zhuluan decoction groups （14， 28， 56 g·kg^-1·d^-1 ）， with 10 rats in each group. The model group and the normal group were given equal volume of distilled water by gavage， once a day， continuous administration for 21 d. The estrous cycle and body weight of rats in each group were detected， and the ovarian organ index and uterine organ index were calculated. The ovarian tissue pathology and ovarian follicle counts at all levels were determined by hematoxylin-eosin （HE） staining. The content of the serum antimullerian hormone （AMH）， follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and inhibin-B （INH-B） of rats was determined by enzyme-linked immunosorbent assay （ELISA）， and the protein expression levels of PI3K， Akt， mTOR in the rat ovarian tissue were determined by Western blot. The microtubule-associated protein 1 light chain 3B （LC3B） protein expression in the rat ovarian tissue was determined by immunohistochemistry. ResultAs compared with the blank group， the estrous cycle of rats in the model group was disordered， the body weight， ovarian organ index， and uterine organ index decreased， the number of primordial follicles decreased， and the number of secondary follicles and atretic follicles increased. In the model group， FSH increased （P<0.01）， LH increased （P<0.05）， AMH level decreased （P<0.05）， the protein expression levels of PI3K， Akt， and mTOR in the ovarian tissue decreased （P<0.01）， and the protein expression level of LC3B increased significantly （P<0.01）. As compared with the model group， the above indexes were improved in the progynova group and different doses of Zhuluan decoction groups， the content of AMH increased （P<0.05）， and FSH decreased （P<0.05）. In the progynova group and different doses of Zhuluan decoction groups， the protein expression level of LC3B decreased obviously （P<0.01）， and the protein expression levels of PI3K， Akt， and mTOR all showed an increasing trend. Moreover， there was a statistically significant difference in the progynova group and low- and medium-dose Zhuluan decoction groups （P<0.05）. ConclusionZhuluan decoction may inhibit the occurrence of excessive autophagy in ovarian granulosa cells by activating the PI3K/Akt/mTOR pathway， thereby reversing the effect of modeling on ovarian reserve in rats.
