ObjectiveTo investigate the therapeutic effects and mechanism of decoctions from four kinds of processed products of Aconiti Radix Lateralis Praeparata（ARLP） in deficiency-cold syndrome. MethodsA total of 36 SD rats were randomly divided into the control group， model group， Shengfupian（SFP） group， Paofuzi（PFZ） group， Heishunpian（HSP） group and Paofupian（PFP） group with 6 rats in each group. Except for the control group， rats in other groups were administered hydrocortisone sodium succinate via intramuscular injection to induce a cold deficiency syndrome model. After 14 consecutive days， each ARLP decoction pieces was administered via continuous gastric lavage at a dose of 12 g·kg^-1·d^-1 for 7 d， while the control and model groups received an equivalent volume of physiological saline. After the end of administration， body weight， spleen weight and thymus weight were measured for calculating the spleen and thymus indexes. Hematoxylin-eosin（HE） staining was used to observe the pathological morphology of adrenal tissue. The fully automatic biochemistry analyzer was used to measure the total cholesterol（TC）， triglyceride（TG）， lactic dehydrogenase（LDH） and lactate（LAC） levels in serum. Enzyme-linked immunosorbent assay（ELISA） was employed to measure the contents of 17-hydroxycorticosteroid（17-OHCS）， cortisol（CORT）， triiodothyronine（T₃）， thyroxine（T₄）， thyrotropin（TSH）， immunoglobulin（Ig） M， IgG， cyclic adenosine monophosphate（cAMP） and cyclic guanosine monophosphate（cGMP）. Western blot was used to measure the protein expression levels of protein kinase A（PKA）， cAMP response element-binding protein（CREB）， silent information regulator 1（Sirt1） and peroxisome proliferator-activated receptor γ coactivator-1α（PGC-1α）. And high performance liquid chromatography（HPLC） was used to determine the content of major alkaloids， followed by Pearson correlation analysis with pharmacodynamic indicators. ResultsAfter modeling， compare with the control group， the model rats exhibited symptoms such as lethargy and loose stools， mild abnormalities were observed in adrenal tissue structure， and both spleen and thymus indices were significantly reduced（P<0.01）. Thyroid， adrenal and immune system functions were suppressed， with decreased serum cAMP level and significantly elevated cGMP level（P<0.01）. Compared with the model group， the adrenal injury by hydrocortisone sodium succinate were repaired and the spleen index were increased significantly in all four ARLP groups（P<0.05， P<0.01）. The thymus index in SFP and PFZ groups were increased significantly（P<0.05）. The contents of T₃， TSH， 17-OHCS and CORT were increased significantly in SFP and PFZ groups（P<0.05）. In addition， the content of IgG in SFP， PFZ and PFP groups were increased significantly（P<0.01）， while the content of IgM in PFZ and HSP groups were also increased significantly（P<0.05）. Regarding the cyclic nucleotide system， PFZ significantly elevated cAMP level while reducing cGMP level（P<0.05）， exhibiting the most pronounced effect among the four decoction pieces. For energy metabolism indicators， PFZ significantly improved abnormal markers including TC， TG， LDH， and LAC（P<0.05）. HSP showed marked improvement effects on TG， LDH， and LAC（P<0.05）. Both PFZ and SFP significantly elevated the expression levels of PKA， CREB， Sirt1， and PGC-1α proteins（P<0.01）. Additionally， the diester alkaloids in ARLP showed a strong positive correlation with TG， IgG， and CORT， a strong negative correlation with LAC， a moderate positive correlation with T₄， and moderate negative correlations with cAMP and spleen index. Monomeric alkaloids showed strong positive correlations with TG and IgG， strong negative correlations with LAC， moderate positive correlations with CORT and T₄， and moderate negative correlations with cAMP and spleen index. However， the content of water-soluble alkaloids showed strong positive correlations with TC， LDH， 17-OHCS， T₃， TSH， and thymus index， moderate positive correlations with cAMP， CORT， T₄， and spleen index， and moderate negative correlation with cGMP. ConclusionAmong different processed ARLP decoction pieces， PFZ processed according to ZHANG Zhongjing's method exhibits the most potent warming and cold-dispelling effects. Its pharmacological actions are mediated through regulating the thyroid， adrenal， immune， cyclic nucleotide systems， and material-energy metabolism pathways. Among these， water-soluble alkaloids show strong or moderate correlations with more indicators of deficiency-cold syndrome and exhibit the highest content in PFZ. Therefore， PFZ processed according to ZHANG Zhongjing's method may exert its warming and cold-dispelling effects through water-soluble alkaloids.

This paper systematically reviews the current status of integrated traditional Chinese and western medicine in the treatment of Helicobacter pylori （Hp） infection， as well as recent progress in clinical and basic research both in China and internationally. It summarizes the advantages of traditional Chinese medicine （TCM） in Hp infection management， including improving Hp eradication rates， enhancing antibiotic sensitivity， reducing antimicrobial resistance， decreasing drug-related adverse effects， and ameliorating gastric mucosal lesions. These advantages are particularly evident in patients who are intolerant to bismuth-containing regimens， those with refractory Hp infection， and individuals with precancerous gastric lesions. An integrated， whole-process management approach and individualized， staged comprehensive treatment strategies combining TCM and western medicine are proposed for Hp infection. Future prevention and control of Hp infection should adopt an integrative Chinese-western medical strategy， emphasizing prevention， strengthening primary care， implementing proactive long-term monitoring， optimizing screening strategies， and advancing the development of novel technologies and mechanistic studies of Chinese herbal interventions. These efforts aim to provide a theoretical basis and practical pathways for the establishment and improvement of Hp infection prevention and control systems.

To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Objective: To understand the impact of childhood trauma on psychological distress among upper grade elemetary school students, and to explore the mediating role of leisure activities in the relationship, so as to provide a basis for developing mental health intervention strategies. Methods: From August to November 2024, a combination of convenience sampling and stratified cluster random sampling was employed to recruit 1 373 fourth to sixth grade students from four primary schools in Harbin. The Childhood Trauma Questionnaire(CTQ), a self designed leisure activity scale (including active and passive leisure activities), and the Kessler Psychological Distress Scale (K10) were used to assess childhood trauma experiences, leisure activities, and levels of psychological distress. Spearman correlation analysis and linear regression analysis were conducted to explore the relationships among childhood trauma, leisure types, leisure time, and psychological distress. Based on the mediation analysis framework proposed by Hayes (Model 4), the mediating role of leisure types in the relationship between childhood trauma and psychological distress was examined. Results: Totally 19.1% of the upper elemetary school students exhibited psychological distress, while 30.2% had experienced childhood trauma. During school days, 64.6% of the students were reported of having leisure time concentrated between 1 and 5 hours per day, whereas 67.4% reported leisure time exceeding 5 hours per day on weekends. After controlling for potential demographic confounders such as gender, grade, ethnicity, household registration, being an only child, parents educational level, co residence, and whether parents are first time married,linear regression analysis showed that childhood trauma experience had positive predictive effect on psychological distress in upper primary school students( β =0.20, P <0.01). Leisure time showed no statistically significant association with psychological distress, both on school days ( β =-0.58 to -0.56) and weekends ( β =0.26- 0.98 )(all P >0.05). Active leisure activities were negatively associated with psychological distress ( β =-0.20), while passive leisure activities were positively associated with psychological distress ( β =0.29)(both P <0.01). Leisure type partially mediated the relationship between childhood trauma and psychological distress, accounting for 11.7% of the indirect effect. Conclusion Childhood trauma experiences positively predict psychological distress in upper elementary school students, and affect psychological distress through active leisure and passive leisure.

Liver fibrosis is the intermediate stage in the progression of many chronic liver diseases to liver cirrhosis， and although there is still a lack of widely accepted and effective chemical or biological agents for reversing liver fibrosis， significant progress has been made in the treatment of liver fibrosis with traditional Chinese medicine. This article elaborates on the molecular mechanisms of different herbal extracts， a single Chinese herb， and Chinese patent drugs in reversing liver fibrosis， such as inhibiting liver inflammation， exerting an effect on lipid peroxidation damage， inhibiting the activation and proliferation of hepatic stellate cells， regulating the synthesis and secretion of pro-fibrogenic factors， and regulating the synthesis and degradation of extracellular matrix， in order to provide more precise options for the treatment of liver fibrosis in the future.

ObjectiveTo investigate the mechanism by which Wendantang regulates the silent information regulator 3 （SIRT3）/peroxisome proliferator-activated receptor-gamma coactivator-1α （PGC-1α） pathway to influence energy metabolism and thereby prevent and treat myocardial ischemia （MI） in a rat model of hyperlipidemia （HL）. MethodsThirty SD rats were randomly assigned into five groups： control， model， low-dose （3.702 g·kg^-1·d^-1） Wendantang， high-dose （7.404 g·kg^-1·d^-1） Wendantang， and positive control （trimetazidine， 0.006 g·kg^-1·d^-1）， with six rats in each group. The control group was fed normally， while the other groups were fed with a high-fat diet for six weeks for the modeling of HL. Subsequently， the drug intervention groups were administrated with corresponding drugs by gavage， and the control and model groups received an equivalent volume of normal saline for 14 days. One hour after the last gavage， the other groups except the control group were injected intraperitoneally with posterior pituitary hormone （30 U·kg^-1） to induce MI. Electrocardiography （ECG） was employed to detect changes in the electrocardiogram. Hematoxylin-eosin staining was performed to observe cardiac pathological changes. Enzyme-linked immunosorbent assay was employed to measure the serum levels of cardiac troponin I（cTnI）， myoglobin （MYO）， and creatine kinase-MB （CK-MB）. Colorimetry was used to determine the levels of total cholesterol （TC） and triglycerides （TG） in the serum and ATP， malondialdehyde （MDA）， and superoxide dismutase （SOD） in the myocardial tissue. Western blot was employed to determine the protein levels of SIRT3， PGC-1α， adenosine monophosphate-activated protein kinase （AMPK）， and phosphorylated AMPK （p-AMPK） in the myocardial tissue. Real-time PCR was employed to measure the mRNA levels of SIRT3， PGC-1α， and AMPKα in the myocardial tissue. ResultsCompared with the control group， the model group showed significant J-point deviation and elevation in the ECG image， increased heart rate， disarrangement of myocardial fibers with unclear boundaries， elevated levels of CK-MB， cTnI， MYO， TC， and TG （P<0.05， P<0.01）， declined levels of SOD and ATP （P<0.01）， down-regulated mRNA levels of SIRT3， PGC-1α， and AMPK （P<0.05）， and down-regulated protein levels of SIRT3， PGC-1α， and p-AMPK （P<0.05）. Compared with the model group， the low-dose and high-dose Wendantang groups and the trimetazidine group showed inhibited J-point deviation and elevation in the ECG image， slowed heart rate， reduced inflammatory cell infiltration， alleviated disarrangement of myocardial fibers， declined levels of CK-MB， cTnI， MYO， TC， and TG （P<0.05， P<0.01）， elevated level of SOD （P<0.01）， up-regulated mRNA levels of SIRT3， PGC-1α， and AMPK （P<0.05， P<0.01） and up-regulated protein levels of SIRT3， PGC-1α， and p-AMPK （P<0.05， P<0.01）. ConclusionWendantang can effectively intervene in HL-associated MI in rats by reducing oxidative stress in myocardial cells， alleviating lipid metabolism disorders， and improving myocardial energy metabolism via the SIRT3/PGC-1α signaling pathway.

Background/Aims: Reflux symptoms frequently present in patients diagnosed with functional dyspepsia (FD). This investigation sought to elucidate the contribution of gastroesophageal reflux in the overlap relationship. Methods: Consecutive patients presenting with reflux symptoms and/or FD symptoms were prospectively included. Comprehensive assessments, including symptoms evaluation, endoscopy, esophageal functional examinations (high-resolution manometry and reflux monitoring), and proton pump inhibitor (PPI) treatment efficacy evaluation, were conducted in these patients. Results: The study enrolled 315 patients, 43.2% of which had concurrent FD symptoms and overlapping reflux symptoms. Notably, a mere 28.7% of patients in the overlap symptoms group had objective gastroesophageal reflux disease evidences (the grade of esophagitis≥ B or the acid exposure time ≥ 4.2%). Functional heartburn was demonstrated to be the main cause of overlapping reflux symptoms(55.1%). Reflux parameters analysis revealed that the reflux burden in the overlap symptoms group paralleled that of the FD symptoms group, with both registering lower levels than the reflux symptoms group (P < 0.05). Furthermore, PPI response rates were notably diminished in the overlap symptoms group (P < 0.001), even for those with objective gastroesophageal reflux disease evidences. Conclusions The study illuminated that overlapping reflux symptoms in FD was common. Strikingly, these symptoms primarily diverged from reflux etiology and exhibited suboptimal responses to PPI intervention. These findings challenge prevailing paradigms and accentuate the imperative for nuanced therapeutic approaches tailored to the distinctive characteristics of overlapping reflux symptoms in the context of FD.

ObjectiveThis study aims to enhance of the farnesyl pyrophosphate（FPP） pool in Saccharomyces cerevisiae by heterologously expressing different farnesyl diphosphate synthases（FPSs） from various plants， thereby increasing the production of terpenoid compounds by the engineered yeast. MethodsRNA from mixed samples of roots， stems， and leaves of seven plants including Arabidopsis thaliana， Rosa rugosa， Artemisia annua， Centella asiatica， Humulus lupulus， Medicago sativa， and Panax ginseng was extracted by column chromatography and reverse transcribed into the first strand of complementary DNA（cDNA）， and based on the transcriptome data of the seven species of plants， sequence-specific primers were designed for CaFPS， RrFPS， MsFPS， HiFPS， PgFPS， AtFPS， and AaFPS， the full-length of the genes was cloned， and the genes were analyzed for bioinformatics in order to construct a pESC yeast shuttle vector. These seven plant-derived FPSs were further heterologously expressed in the previous constructed β-elemene-producing yeast， and the yield of β-elemene was indicated for their catalytic acivities. ResultsThe coding sequences of CaFPS， RrFPS， MsFPS， HiFPS， PgFPS， AtFPS， and AaFPS were all of 1 021 bp in length and encoding 301 amino acids， all of which were similarly related to the endogenous FPS-encoding gene（ERG20） in S. cerevisiae. After heterologous expression， RrFPS was identified as the most effective in catalyzing the synthesis of FPP from isopentenyl pyrophosphate（IPP） and dimethylallyl pyrophosphate（DMAPP）. Compared to the control strains， the RrFPS overexpressed yeast strains YB-1-Rr and YB-3-Rr increased the production of β-elemene by 231.25% and 189.3%， respectively. ConclusionBy comparing the functions of FPS-encoding genes from seven different plant sources， it is determined that the protein encoded by the RrFPS from R. rugosa has the best catalytic ability， which can provide key genetic elements for the construction of engineered yeast strain constructs with high terpenoid production.

Ovarian cancer （OC） is one of the most common malignant tumors in women， with the mortality rate being the highest among gynaecological malignant tumors. As the atypical symptoms of OC are difficult to be detected in the early stage， most patients are already in the advanced stage when being diagnosed. As a result， the clinical treatment has limited effects. Currently， the main therapies for OC are surgery and chemotherapy， while their drug resistance and adverse reactions seriously reduce the quality of life of patients. In recent years， traditional Chinese medicine （TCM） has attracted the attention of clinicians and researchers because of its high efficacy， low toxicity， and mild side effects. According to the TCM philosophy of treatment based on syndrome differentiation， the Chinese medicines with multiple targets， wide range， and mild side effects can be screened based on the molecular targets involved in the occurrence and development of OC， which can bring out the unique advantages of TCM in the treatment of OC. Modern studies have shown that the occurrence and development of OC are closely related to the abnormal expression of multiple signaling pathways. The continued abnormal activation of the signal transducer and activator of transcription 3 （STAT3） signaling pathway can lead to abnormal proliferation and malignancy of OC. cause abnormal proliferation and malignant transformation of OC， which is closely related to the development of OC. In addition， studies have shown that Chinese medicine can inhibit the proliferation， angiogenesis， invasion， and metastasis and promote the autophagy and apoptosis of OC cells by regulating the Janus kinase 2 （JAK2）/STAT3 signaling pathway， providing new therapeutic strategies and ideas for the prevention and treatment of OC. This paper summarizes the role of JAK2/STAT3 signaling pathway in OC development by reviewing the relevant articles and reviews the mechanism and research progress of active components and compound prescriptions of Chinese medicine intervening in OC development by regulating the JAK2/STAT3 signaling pathway. This review is expected to provide a systematic reference for clinical research and drug development of OC.

AIM: To explore the factors affecting the whole-eye astigmatism after pterygium excision combined with autologous limbal stem cell transplantation.METHODS: A retrospective analysis was conducted on the medical records of 42 patients(42 eyes)with primary pterygium admitted in the ophthalmology department of Xijing Hospital from January 2023 to October 2023. They underwent pterygium excision combined with autologous limbal stem cell transplantation. The maximum invasion depth of pterygium into the cornea was measured with anterior segment optical coherence tomography(AS-OCT)before operation, the length of the pterygium invading cornea, the width of the limbus and the area of the invading cornea were measured during the operation, and three-dimensional values of corneal astigmatism of anterior segment, index of surface variance(ISV), index of vertical asymmetry(IVA), best corrected visual acuity(BCVA)and whole-eye astigmatism were collected before and at 1 mo after surgery. Patients with astigmatism ≤0.50 D or >0.50 D of the whole eye at 1 mo after surgery were assigned to group A and B, respectively. The differences of clinical data before and at 1 mo after surgery between the two groups, and the correlation between pre-operative clinical indicators and whole-eye astigmatism were analyzed. The decision tree algorithm was performed to explore the influencing factors of whole-eye astigmatism at 1 mo postoperatively.RESULTS: The maximum invasion depth of pterygium in the group A was significantly less than that in the group B [80.00(40.00, 180.00)μm vs 175.00(123.00, 190.00)μm, P=0.002]. Preoperative BCVA(LogMAR), whole-eye astigmatism, cornea astigmatism, ISV, IVA and maximum invasion depth of pterygium were positively correlated with whole-eye astigmatism at 1 mo after surgery(rs=0.317, P=0.041; rs=0.545, P<0.001; rs=0.448, P=0.003; rs=0.389, P=0.011; rs=0.382, P=0.013; rs=0.391, P=0.010). The decision tree algorithm screened out two influential factors: the maximum invasion depth of pterygium into the cornea and preoperative whole-eye astigmatism. The risk of whole-eye astigmatism >0.50 D at 1 mo after operation was higher with maximum invasion depth of pterygium into the cornea >95 μm than that with ≤95 μm. Among the patients with whole-eye astigmatism >2.63 D before operation, the probability of residual whole-eye astigmatism >0.50 D was 88.9%, and the predictive model AUC was 0.804.CONCLUSION: The whole-eye astigmatism after pterygium resection is mainly affected by the maximum invasion depth of pterygium into the cornea and preoperative whole-eye astigmatism. When the maximum invasion depth of pterygium into the corneal is >95 μm and the whole-eye stigmatism is >2.63 D before surgery, the patient should receive surgical treatment as soon as possible in order to obtain good clinical benefits.
