ObjectiveTo observe the clinical efficacy of Sanren Runchang formula in treating constipation-predominant irritable bowel syndrome （IBS-C） by regulating the brain-gut axis and the effects of the formula on serum levels of 5-hydroxytryptamine （5-HT）， vasoactive intestinal peptide （VIP）， and substance P （SP）. MethodsA randomized controlled design was adopted， and 72 IBS-C patients meeting Rome Ⅳ criteria were randomized into observation and control groups （36 cases）.The observation group received Sanren Runchang formula granules twice daily， and the control group received lactulose oral solution daily for 4 weeks. IBS Symptom Severity Scale （IBS-SSS）， IBS Quality of Life Scale （IBS-QOL）， and Bristol Stool Form Scale （BSFS） were used to assess clinical symptoms， and bowel movement frequency was recorded. The Self-Rating Anxiety Scale （SAS） and Self-Rating Depression Scale （SDS） were employed to evaluate psychological status. ELISA was employed to measure the serum levels of 5-HT， VIP， and SP. ResultsThe total response rate in the observation group was 91.67% （33/36）， which was higher than that （77.78%， 28/36） in the control group （χ²=4.50， P<0.05）. After treatment， both groups showed increased defecation frequency and BSFS scores， decreased IBS-SSS total score， abdominal pain and bloating scores， IBS-QOL health anxiety， anxiety， food avoidance， and behavioral disorders scores， SAS and SDS scores， serum 5-HT and VIP levels， and increased SP levels （P<0.05， P<0.01）. Moreover， the observation group showed more significant changes in the indicators above than the control group （P<0.05， P<0.01）. The SP level showed no significant difference between the two groups. During the 4-week follow-up， the recurrence rate was 5.88% in the observation group and 31.25% in the control group. No adverse events occurred in observation group， and 2 cases of mild diarrhea occurred in the control group. ConclusionSanren Runchang formula demonstrated definitive efficacy in alleviating gastrointestinal symptoms and improving the psychological status and quality of life in IBS-C patients， with a low recurrence rate. The formula can regulate serum levels of neurotransmitters such as 5-HT and VIP， suggesting its potential regulatory effect on the brain-gut axis through modulating neurotransmitters and neuropeptides. However， its complete mechanism of action requires further investigation through detection of additional brain-gut axis-related biomarkers.

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 explore the distribution characteristics and influencing factors of adverse reactions in whole blood donation in Jinan, Shandong, so as to provide evidence for the prevention and control of such adverse reactions in this region. Methods: A retrospective analysis was conducted on whole blood donors and adverse reaction cases in Jinan during 2023. To explore influencing factors of adverse reactions, univariate and multivariate logistic regression analyses were used to examine the relationships between adverse reactions and factors such as gender, age, donation organization mode, donation frequency, donation volume, time slot, and health examination results. Results: A total of 122 961 whole blood donations were recorded in Jinan in 2023. Donation-related adverse reactions occurred in 2 054 cases, with an incidence rate of 1.67%. Univariate analysis revealed significant differences in the incidence of adverse reactions across donor characteristics: the rate was higher in females (2.35%, 921/39 192) than in males (1.35%, 1 133/83 769), donors aged 18-25 years had the highest incidence (3.48%, 1 799/51 733), the incidence in group donations (3.13%, 1,737/55 534) was significantly higher than in individual donations (0.47%, 317/67 427), and insufficient blood collection was closely associated with adverse reactions (all P<0.001). Multivariate logistic regression analysis identified group donation, female gender, and a pulse rate of 81-99 beats per minute as risk factors for adverse reactions (all P<0.001), while systolic blood pressure of 116-139 mmHg and diastolic blood pressure of 76-89 mmHg were protective factors (all P<0.05). Compared to younger and lower-weight donor groups, older and higher-weight donors had a significantly lower risk of adverse reactions (all P<0.05). Donors giving 400 mL had a higher risk than those giving 200 mL (P<0.001). In addition, compared with the donation time slot of 7:00-8:59, the risk of adverse reactions was significantly higher during 9:00-16:59, with the time slot of 13:00-14:59 showing the most prominent risk (all P<0.05). However, no statistically significant difference was observed between the time slot of 17:00-20:59 and that of 7:00-8:59 (P>0.05). The primary clinical manifestation of adverse reactions was donation-related vasovagal reaction, with mental tension being the leading precipitating factor, accounting for 69.08% (1 419/2 054) of cases. Conclusion: The occurrence of adverse reactions in whole blood donation in the Jinan is influenced by multiple factors, including donor demographic characteristics, donation organization mode, physiological indicators, and time of donation. It is recommended to enhance the identification and intervention for high-risk groups, and optimize donation processes and service models to reduce the incidence of adverse reactions, thereby ensuring donor safety and blood quality.

The common marmoset (Callithrix jacchus) is a species of the genus Callithrix in the primate family Callitrichidae. Common marmosets are an important scientific research resource for the study of neuroscience, medicine, and pharmacy. The feeding and breeding of common marmosets provide important support for scientific research. At present, common marmoset resources in China are at a critical stage of development. This paper takes the Center for Excellence in Brain Science and Intelligence Technology of the Chinese Academy of Sciences (hereafter referred to as CEBSIT) as an example to discuss the experience of common marmoset feeding, breeding and genetic management. In terms of breeding environment and facilities, on the basis of the national standard, more stringent environmental parameter standards are implemented for environmental temperature, relative humidity, the number of air exchanges, and the average concentration of sedimentation bacteria. Two kinds of cages for common marmoset breeding and experimentation are designed. According to the differences in facility conditions and staffing, a cleaning and maintenance method combining "dry rearing" and "wet rearing" is introduced. In terms of feeding management, in order to meet the high nutritional needs of common marmosets, CEBSIT prepares special formulated diets, and introduces the transition method of common marmosets from diets mixed with formulated rations and pellets to exclusive commercial diets, and strictly regulates the operation procedures of formulated diets for common marmosets, and has accumulated a series of methods for preventing nutritional and metabolic diseases in common marmosets. In terms of animal health management, the health of common marmosets is ensured through measures such as regular quarantine, isolation and treatment, and epidemic prevention, and the health inspection process of common marmosets is described in detail, and hierarchical and classified management is carried out according to the physical condition of common marmosets. This paper also briefly describes the treatment of diarrhea and pneumonia that are common in common marmosets. In terms of breeding management, it covers the selection of breeding common marmosets, combining pairs of common marmosets into the same cage for breeding, group splitting and hand-rearing of infant common marmosets, and introduces the method of reintroducing hand-reared infant common marmosets to parental care from the perspective of animal welfare. In terms of genetic management, the common marmoset population in CEBSIT is maintained as a closed colony and follows a non-inbreeding method. CEBSIT has developed an inbreeding screening system to check pedigree information before pairing to avoid inbreeding. Under conditions without introducing new individuals from outside, CEBSIT has continuously bred the colony for 5 generations while maintaining genetic heterozygosity. This paper only discusses the feeding, breeding and genetic management of the common marmoset and aims to provide a useful reference for other institutions engaged in common marmoset breeding.

OBJECTIVE To explore the improvement effect and potential mechanism of modified Yanghe decoction on bone destruction in rats with breast cancer bone metastasis based on the receptor-interacting serine/threonine-protein kinase 1 （RIPK1）/RIPK3 pathway. METHODS The rat model of breast cancer bone metastasis was established by injecting a suspension of breast cancer cells into the bone marrow cavity. The rats with successful modeling were randomly divided into a model group （intragastric administration of equal volume of normal saline）， modified Yanghe decoction low-， medium-， and high-dose groups （intragastric administration of corresponding decoction at 1.30， 2.60 and 5.20 g/kg， calculated by the dosage of crude drug）， high-dose modified Yanghe decoction+si-RIPK1 group （intragastric administration of corresponding decoction at 5.20 g/kg， calculated by the dosage of crude drug； simultaneous injection of small interfering RNA for RIPK1 via the tail vein）， and high-dose modified Yanghe decoction+si-NC group （intragastric administration of corresponding decoction at 5.20 g/kg， calculated by the dosage of crude drug； simultaneous injection of small interfering RNA for negative control via the tail vein）， with 12 rats in each group. Another 12 healthy rats were selected as the control group and were given the same volume of normal saline intragastrically， once a day， for 14 consecutive days. Body weight was measured before administration and at the end of the last administration. The mechanical pain threshold and thermal pain threshold were measured， and the bone destruction， pathological changes and osteoclast formation of the tibia were observed. The positive expression of receptor activator of nuclear factor-κB （RANK） and receptor activator of nuclear factor-κB ligand （RANKL） in the tibial tissue， as well as the phosphorylation levels of RIPK1， RIPK3 and mixed lineage kinase domain-like protein （MLKL） were detected. RESULTS Compared with the control group， the tumor cells of tibia tissues in rats of the model group showed significant proliferation and diffuse infiltration into the bone marrow cavity. Extensive areas of tumor necrosis of cells， severe bone destruction， thinning of the bone cortex， and damage to the bone trabeculae were observed. The body weight （before administration and at the end of the last administration）， mechanical pain threshold， thermal pain threshold， and the phosphorylation levels of RIPK1， RIPK3 and MLKL were decreased significantly； the tumor volume， the proportion of bone destruction area， the number of osteoclasts， and the positive expressions of RANK and RANKL were increased/up-regulated significantly （P＜0.05）. Compared with the model group， the above pathological changes in the tibial tissues of rats in modified Yanghe decoction low-， medium- and high-dose groups were all alleviated， and all quantitative indicators showed dose-dependent improvement （P＜0.05）. After silencing RIPK1， the aforementioned beneficial effects of high-dose modified Yanghe decoction were significantly weakened （P＜0.05）.CONCLUSIONSModified Yanghe decoction can alleviate bone destruction in rats with breast cancer bone metastasis. The above effect is related to the activation of the RIPK1/RIPK3 pathway.

Surgical treatment is one of the key approaches for non-small cell lung cancer (NSCLC). Regular postoperative follow-up is crucial for early detection and timely management of tumor recurrence, metastasis, or second primary tumors. A scientifically sound and reasonable follow-up strategy not only extends patient survival but also significantly improves quality of life, thereby enhancing overall prognosis. This consensus aims to build upon the previous version by incorporating the latest clinical research advancements and refining postoperative follow-up protocols for early-stage NSCLC patients based on different treatment modalities. It provides a scientific and practical reference for clinicians involved in the postoperative follow-up management of NSCLC. By optimizing follow-up strategies, this consensus seeks to promote the standardization and normalization of lung cancer diagnosis and treatment in China, helping more patients receive high-quality care and long-term management. Additionally, the release of this consensus is expected to provide insights for related research and clinical practice both domestically and internationally, driving continuous development and innovation in the field of postoperative management for NSCLC.

BACKGROUND:Knee osteoarthritis(KOA)is a common chronic inflammatory disease that causes damage to joint cartilage and surrounding tissues.Immune cells play an important role in the immune-inflammatory response in knee osteoarthritis,but the specific mechanisms involved are still not fully understood. OBJECTIVE:To evaluate the potential causal relationship between 731 immune cell phenotypes and the risk of knee osteoarthritis using Mendelian randomization. METHODS:Summary statistics of genome-wide association studies(GWAS)for 731 immune cell phenotypes(from GCST0001391 to GCST0002121)obtained from the GWAS catalog and GWAS data for knee osteoarthritis from the IEUGWAS database(ebi-a-GCST007090)were used.Inverse variance-weighted method,MR-Egger regression,weighted median method,weighted mode method,and simple mode method were employed to investigate the causal relationship between immune cells and knee osteoarthritis.Sensitivity analyses were conducted to assess the reliability of the Mendelian randomization results.Reverse Mendelian randomization analysis was also performed using the same methods. RESULTS AND CONCLUSION:The forward MR analysis indicated significant causal relationships(FDR<0.20)between knee osteoarthritis and four immune cell phenotypes,namely CD27 on CD24+CD27+in B cells(OR=1.026,P=0.000 26,Pfdr=0.18),CD33 on CD33dim HLA DR-in myeloid cells(OR=1.014,P=0.000 50,Pfdr=0.18),and CD45RA+CD28-CD8br%CD8br in Treg cells(OR=1.001,P=0.000 78,Pfdr=0.18),and PDL-1 on monocytes in mononuclear cells(OR=0.952,P=0.000 98,Pfdr=0.18).These immune cell phenotypes showed direct positive or negative causal associations with the risk of knee osteoarthritis.Reverse Mendelian randomization analysis revealed no significant causal relationships(FDR<0.20)between knee osteoarthritis as exposure and any of the 731 immune cell phenotypes.The results of sensitivity analysis show that the P-values of the Cochran's Q test and the MR-Egger regression method for bidirectional Mendelian randomization were both greater than 0.05,indicating that there is no significant heterogeneity and pleiotropy in the causal effect analysis between immune cell phenotypes and knee osteoarthritis.To conclude,there may be four potential causal relationships between immune cell phenotypes,such as CD27 on CD24+CD27+cells,CD33 on CD33dim HLA DR-cells,CD45RA+CD28-CD8br%CD8br cells,and PDL-1 on monocytes,and knee osteoarthritis.These findings provide valuable clues for studying the biological mechanisms of knee osteoarthritis and exploring early prevention and treatment strategies.They also offer new directions for the development of intervention drugs.

Type 2 diabetes mellitus （T2DM） and hypertension are common and frequent chronic non-communicable diseases， which often coexist in clinical practice， resulting in a large number of cardiovascular events and deaths， and their case fatality rate far exceeds that of other factors such as dyslipidemia and obesity. Based on the diagnostic standards， guidelines， and animal model evaluation methods of T2DM with hypertension at home and abroad， this study summarized， evaluated， and analyzed the characteristics of the existing animal models of T2DM with hypertension based on the clinical symptoms in traditional Chinese and Western medicine. The animal models showing high fitting degrees with the clinical symptoms in Western medicine are mainly established by injection of streptozocin （STZ） in SHR rats in the surgical induction and chemical induction methods and feeding a high-fat and high-salt diet combined with STZ injection in SD rats in the dietary induction methods. The models showcasing high fitting degrees with the clinical symptoms in traditional Chinese medicine （TCM） are mainly established by the surgical induction method. Considering the fitting degrees and the advantages and disadvantages， the ideal modeling method for T2DM with hypertension is the two-kidney， one clip （2K1C） method （a surgical induction method） combined with feeding a high-fat and high-sugar diet and STZ injection. However， the available models lack the characteristics of TCM and the evaluation indicators have poor specificity. This study found that there are few animal models of T2DM with hypertension considering the characteristics of both disease and syndrome， which may be related to the identification and attribution of TCM syndromes in animal macroscopic information. In view of this problem， it is suggested that the evaluation criteria should be established and improved for the animal models combining disease and syndrome， which can help to evaluate the fitting degree of the pathological characteristics of different syndromes in the animal models of T2DM with hypertension. In this way， ideal animal models of T2DM with hypertension can be established to simulate the disease occurrence and development in the human body. The animal models are expected to provide an ideal approach for the further research on the pathogenesis of T2DM and its prevention and treatment with TCM， which is of great significance for the treatment and prevention of T2DM with hypertension and the prognosis of its complications. At the same time， breakthroughs in the basic syndrome models of comorbidities are expected to lay a foundation for the leapfrog development of TCM research.

Immunoglobulin A nephropathy （IgAN） is the primary glomerulonephritis with the highest incidence rate in the world. It is also the main cause of end-stage renal disease （ESRD） in China， which has brought heavy economic burden to the society and patient families. Traditional Chinese medicine （TCM） has certain advantages in treating IgAN. In TCM， IgAN is classified into consumptive disease， hematuria， and edema categories， with the location in the kidney and involving the lung， liver， and spleen. Professor Ren Jixue， a master of TCM， believes that kidney deficiency and spleen deficiency are the root causes of IgAN， and the throat is the source of the disease. He proposed the theory of throat-kidney correlation and used the method of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat to treat IgAN， achieving significant therapeutic effects. Studies have shown that IgAN is closely related to mucosal immune defense. IgAN patients often experience recurrent and gradually worsening symptoms due to mucosal infections， and polymeric Ig receptor （PIgR） is an important component of mucosal defense function. The lack of PIgR leads to the accumulation of IgA molecules in the mucosal lamina propria， and the molecules enter the bloodstream in large quantities and ultimately deposit in the kidneys， causing kidney damage. Complement regulatory protein complement receptor type 1 （CR1） exists on red blood cells and glomeruli and has the function of inhibiting the activation and differentiation of B cells， clearing immune complexes， and inhibiting excessive activation of the complement system. Therefore， regulating the immune defense function through the mucosal-renal axis mediated by PIgR-CR1 will be an important target for preventing and treating IgAN. Based on the theory of throat-kidney correlation， this article explores the effects and molecular mechanisms of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat in preventing and treating IgAN by regulating the mucosal-kidney axis mediated by PIgR-CR1. It provides effective theoretical support and a scientific basis for TCM prevention and treatment of IgAN based on the theory of throat-kidney correlation.
