Basket trial, as an innovative clinical trial design concept, marks the transformation of medical research from the traditional large-scale and single-disease treatment to the precise and individualized treatment. By gradually incorporating the Bayesian method during development, the trial design becomes more scientific and reasonable and increases its efficiency. The fundamental principle of the Bayesian method is the utilization of prior knowledge in conjunction with new observational data to dynamically update the posterior probability. This flexibility enhances the basket trial's capacity to effectively adapt to variations during the research process. Consequently, it enables researchers to dynamically adjust research strategies based on accumulated data and improve the predictive accuracy regarding treatment responses. In addition, the design concept of the basket trial aligns with the traditional Chinese medicine(TCM) principle of "homotherapy for heteropathy". The principle of "homotherapy for heteropathy" emphasizes that under certain conditions, different diseases may have the same treatment. Similarly, basket trials allow using a uniform trial design across multiple diseases, offering enhanced operational and significant practical value in the realm of TCM, particularly within the context of syndrome-based disease research. By introducing basket trials, the design of TCM clinical studies will be more scientific and yield higher-quality evidence. This study systematically categorized various Bayesian methods and models utilized in basket trials, evaluated their strengths and weaknesses, and identified their appropriate application contexts, so as to offer a practical guide for designing basket trials in the realm of TCM.

OBJECTIVE: To investigate the predictive value of endothelial activation and stress index (EASIX) for the prognosis of patients with mantle cell lymphoma (MCL). METHODS: A retrospective analysis was conducted to assess prognosis and compare the clinical features of patients diagnosed with MCL who were admitted to the Affiliated Hospital of Xuzhou Medical University from January 2010 to June 2023, had therapeutic indications and received standard treatment. RESULTS: A total of 66 patients were included and divided into high EASIX group and low EASIX group, according to a cutoff value of 0.97 determined by the receiver operating characteristic (ROC) curve. Multivariate Cox regression analysis showed that prealbumin <0.2 g/L, high EASIX, and ECOG PS score ≥2 were independent risk factors influencing overall survival (OS) in MCL patients. The median OS of patients in the high and low EASIX group was 13.0 and 37.5 months, and the median progression-free survival was 8.8 and 26.0 months, respectively. The proportions of patients with ECOG PS score ≥2 and prealbumin <0.2 g/L at onset significantly increased in the high EASIX group compared to those in the low EASIX group. CONCLUSION At the time of initial diagnosis, EASIX can serve as an independent prognostic indicator impacting OS in patients with MCL. Furthermore, patients in the high EASIX group experience a poorer prognosis and shorter survival duration compared with those in the low EASIX group.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Tumor is one of the serious problems threatening human health. There are some limitations in the delivery of commonly used tumor therapy technologies, and the therapeutic effect is not satisfactory, so new anti-tumor strategies need to be developed. The process of tumor cells using glycolysis to produce energy under aerobic conditions is called aerobic glycolysis, which is closely related to tumor growth, proliferation and metastasis, and can provide a new target spot for tumor treatment. Nano drug delivery system has been widely used in targeted tumor therapy because of its advantages of targeted drug delivery, improved anti-tumor efficacy and reduced toxic side effects. Numerous studies have shown that more and more nano drug delivery systems regulates aerobic glycolytic metabolism by targeting to potential targets such as signaling factors or reaction products of aerobic glycolytic process in tumors, and therefore enhance the anti-tumor effect. This paper reviews the application of nano drug delivery system in regulating tumor aerobic glycolysis, and provides theoretical references for realizing efficient targeted tumor therapy.

Objective To explore early postoperative gait characteristics and clinical outcomes after total knee arthroplasty(TKA).Methods From February 2023 to July 2023,26 patients with unilateral knee osteoarthritis(KOA)were treated with TKA,including 4 males and 22 females,aged from 57 to 85 years old with an average of(67.58±6.49)years old;body mass in-dex(BMI)ranged from 18.83 to 38.28 kg·m-2 with an average of(26.43±4.15)kg·m-2;14 patients on the left side,12 pa-tients on the right side;according to Kellgren-Lawrence(K-L)classification,6 patients with grade Ⅲ and 20 patients with grade Ⅳ;the courses of disease ranged from 1 to 14 years with an average of(5.54±3.29)years.Images and videos of standing up and walking,walking side shot,squatting and supine kneeling were taken with smart phones before operation and 6 weeks after operation.The human posture estimation framework OpenPose were used to analyze stride frequency,step length,step length,step speed,active knee knee bending angle,stride length,double support phase time,as well as maximum hip flexion angle and maximum knee bending angle on squatting position.Western Ontario and McMaster Universities(WOMAC)arthritis index and Knee Society Score(KSS)were used to evaluate clinical efficacy of knee joint.Results All patients were followed up for 5 to 7 weeks with an average of(6.00±0.57)weeks.The total score of WOMAC decreased from(64.85±11.54)before op-eration to(45.81±7.91)at 6 weeks after operation(P＜0.001).The total KSS was increased from(101.19±9.58)before opera-tion to(125.50±10.32)at 6 weeks after operation(P＜0.001).The gait speed,stride frequency and stride length of the affected side before operation were(0.32±0.10)m·s-1,(96.35±24.18)steps·min-1,(0.72±0.14)m,respectively;and increased to(0.48±0.11)m·s 1,(104.20±22.53)steps·min-1,(0.79±0.10)m at 6 weeks after operation(P＜0.05).The lower limb support time and active knee bending angle decreased from(0.31±0.38)sand(125.21±11.64)° before operation to(0.11±0.04)s and(120.01±13.35)° at 6 weeks after operation(P＜0.05).Eleven patients could able to complete squat before operation,13 patients could able to complete at 6 weeks after operation,and 9 patients could able to complete both before operation and 6 weeks after operation.In 9 patients,the maximum bending angle of crouching position was increased from 76.29° to 124.11° before operation to 91.35° to 134.12° at 6 weeks after operation,and the maximum bending angle of hip was increased from 103.70° to 147.25° before operation to 118.61° to 149.48° at 6 weeks after operation.Conclusion Gait analysis technology based on artificial intelligence image recognition is a safe and effective method to quantitatively identify the changes of pa-tients'gait.Knee pain of KOA was relieved and the function was improved,the supporting ability of the affected limb was im-proved after TKA,and the patient's stride frequency,stride length and stride speed were improved,and the overall movement rhythm of both lower limbs are more coordinated.

This study aimed to parallelly investigate the cardioprotective activity of Cinnamomi Ramulus formula granules(CRFG) and Cinnamomi Cortex formula granules(CCFG) against acute myocardial ischemia/reperfusion injury(MI/RI) and the underlying mechanism based on the efficacy of "warming and coordinating the heart Yang". Ninety male SD rats were randomly divided into a sham group, a model group, CRFG low and high-dose(0.5 and 1.0 g·kg~(-1)) groups, and CCFG low and high-dose(0.5 and 1.0 g·kg~(-1)) groups, with 15 rats in each group. The sham group and the model group were given equal volumes of normal saline by gavage. Before modeling, the drug was given by gavage once a day for 7 consecutive days. One hour after the last administration, the MI/RI rat model was established by ligating the left anterior descending artery(LAD) for 30 min ischemia followed by 2 h reperfusion except the sham group. The sham group underwent the same procedures without LAD ligation. Heart function, cardiac infarct size, cardiac patho-logy, cardiomyocyte apoptosis, cardiac injury enzymes, and inflammatory cytokines were determined to assess the protective effects of CRFG and CCFG against MI/RI. The gene expression levels of nucleotide-binding oligomerization domain-like receptor family pyrin domain protein 3(NLRP3) inflammasome, apoptosis-associated speck-like protein containing a CARD(ASC), cysteinyl aspartate specific proteinase-1(caspase-1), Gasdermin-D(GSDMD), interleukin-1β(IL-1β), and interleukin-18(IL-18) were determined by real-time quantitative polymerase chain reaction(RT-PCR). The protein expression levels of NLRP3, caspase-1, GSDMD, and N-GSDMD were determined by Western blot. The results showed that both CRFG and CCFG pretreatments significantly improved cardiac function, decreased the cardiac infarct size, inhibited cardiomyocyte apoptosis, and reduced the content of lactic dehydrogenase(LDH), creatine kinase MB isoenzyme(CK-MB), aspartate transaminase(AST), and cardiac troponin Ⅰ(cTnⅠ). In addition, CRFG and CCFG pretreatments significantly decreased the levels of IL-1β, IL-6, and tumor necrosis factor-α(TNF-α) in serum. RT-PCR results showed that CRFG and CCFG pretreatment down-regulated the mRNA expression levels of NLRP3, caspase-1, ASC, and downstream pyroptosis-related effector substances including GSDMD, IL-18, and IL-1β in cardiac tissues. Western blot revealed that CRFG and CCFG pretreatments significantly decreased the protein expression levels of NLRP3, caspase-1, GSDMD, and N-GSDMD in cardiac tissues. In conclusion, CRFG and CCFG pretreatments have obvious cardioprotective effects on MI/RI in rats, and the under-lying mechanism may be related to the inhibition of NLRP3/caspase-1/GSDMD signaling pathway to reduce the cardiac inflammatory response.

We used network pharmacology to predict the mechanism in the treatment of rheumatoid arthritis (RA) via modified Gan Cao Fu Zi Decoction (GCFZ), and validated the results of the analysis and explored the pharmacodynamic effects of GCFZ through animal experiments. Firstly, TCMID, SymMap, HERB, STITCH and GEO databases were utilized to obtain the target genes of GCFZ for the treatment of RA, which yielded a total of 1 250 differentially expressed genes for RA, 534 genes for GCFZ targets and 83 intersecting genes. Then functional enrichment analysis of the intersecting genes was performed through GO and KEGG databases, and the results revealed that GCFZ and its active ingredients mainly functioned through cytokine pathways, where chemokine signaling pathway and tumor necrosis factor (TNF) signaling pathway were enriched with a high number of genes. Cytoscape 3.8.0 software was used to construct the drug-target-disease network and screen key proteins, which included TNF, C-X-C chemokine ligand 8 (CXCL8), C-X-C chemokine ligand 10 (CXCL10), C-C chemokine ligand 5 (CCL5), C-X-C chemokine ligand 2 (CXCL2) and C-X-C chemokine receptor type 4 (CXCR4). The molecular docking technology was used to confirm the binding ability of the main active ingredients of GCFZ to the core proteins. Additionally, the therapeutic effects of GCFZ in low (4 g·kg^-1), medium (8 g·kg^-1) and high (16 g·kg^-1) dose groups were investigated by constructing the collagen-induced arthritis (CIA) rat model. X-ray imaging approach, HE staining and Safranin O-Fast Green staining showed that GCFZ treatment significantly improved bone destruction, synovial hyperplasia and cartilage damage in CIA rats, while immunofluorescence results showed that GCFZ treatment could regulate the expression of TNF, CXCL8 and CCL5. In summary, our results indicate that GCFZ contains a variety of small molecule pharmacodynamic substances, which can exert therapeutic effects via multiple targets and pathways, and obviously reduce the symptoms of arthritis in CIA rats. This animal experiment of our research was approved by the Experimental Animal Management and Ethics Committee of Bengbu Medical College.
