OBJECTIVE: To reveal the molecular basis of knee osteoarthritis (KOA) with Yang deficiency and blood stasis syndrome by analyzing the gene expression profiles in synovial fluid and blood of KOA patients with this syndrome. METHODS: A total of 80 KOA patients were recruited from October 2022 to June 2024, including 40 cases in the non-Yang deficiency and blood stasis group (27 males and 13 females), with an average age of (61.75±3.45) years old;and 40 cases in the Yang deficiency and blood stasis group (22 males and 18 females), with an average age of (62.00±2.76) years old. The levels of body mass index (BMI), high-density lipoprotein (HDL), low-density lipoprotein (LDL), fibrinogen, total cholesterol, and D-dimer were recorded and summarized. Blood and synovial fluid samples from patients were collected for gene expression profile microarray sequencing, and then PCR and immunohistochemistry were used for clinical verification on the patients' synovial fluid and cartilage samples. RESULTS: Logistic regression analysis showed that compared with KOA patients with non-Yang deficiency and blood stasis syndrome, those with Yang deficiency and blood stasis syndrome had increased BMI, LDL, fibrinogen, total cholesterol, and D-dimer, and decreased HDL, with a clear correlation between the two groups. There were 562 differential genes in the blood, among which 322 were up-regulated and 240 were down-regulated;755 differential genes were found in the synovial fluid, with 350 up-regulated and 405 down-regulated. KEGG signaling pathway analysis of synovial fluid revealed changes in lipid metabolism-related pathways, including cholesterol metabolism, fatty acid metabolism, and PPARG signaling pathway. Analysis of the involved differential genes identified 6 genes in synovial fluid that were closely related to lipid metabolism, namely LRP1, LPL, ACOT6, TM6SF2, DGKK, and PPARG. Subsequently, PCR and immunohistochemical verification were performed using synovial fluid and cartilage samples, and the results were consistent with those of microarray sequencing. CONCLUSION This study explores the clinical and genomic correlation between traditional Chinese medicine syndromes and knee osteoarthritis from the perspective of lipid metabolism, and proves that abnormal lipid metabolism is closely related to KOA with Yang deficiency and blood stasis syndrome from both clinical and basic aspects.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the biological mechanisms underlying the effect of the Chinese herbal medicine Oxalis cor-niculata on human prostate cancer PC-3 cells.Methods:Through in vitro experiment,we treated human prostate cancer PC-3 cells with different concentrations of Oxalis corniculata,assessed the viability of the cells by MTT assay,examined their apoptosis by flow cytometry,evaluated their migration and invasiveness by Transwell assay,and determined the expressions of the proteins p65,p-p65,IκBα and p-IκBα in the NF-κB pathway using protein imprinting technology.Results:Compared with the blank control,Oxalis cor-niculata significantly inhibited the proliferation and induced the apoptosis of the PC-3 cells(P＜0.05),suppressed their migration and invasiveness in a dose-dependent manner(P＜0.05),and upregulated the expression of IκBα and downregulated those of p-p65 and p-IKBα in the NF-κB pathway(P＜0.05).Conclusion:Oxalis corniculata can inhibit the proliferation,migration and inva-siveness and induce the apoptosis of human prostate cancer PC cells,which may be attributed to its abilities of inhibiting the expres-sions of p-p65 and p-IκBα and regulating the activity of the NF-κB pathway.

OBJECTIVETo investigate the factors of long-turn survival of liver cancer after surgical treatment.

METHODSFive hundred and twenty-two cases of liver cancer that received surgical treatment in 14 years were analyzed retrospectively.

RESULTSComparison between the small liver cancer (< 5 cm) and the greater one (> 10 cm) revealed that the small liver cancer had a higher survival rates than the greater one [3 year (61.25 +/- 4.41)% versus (45.90 +/- 6.98)%; 5 year (53.84 +/- 5.68)% versus (30.21 +/- 10.23)%]. There were same results between single-nodule and two or more than two nodule [3 year (61.86 +/- 3.69)% versus (38.31 +/- 4.97)%; 5 year (55.40 +/- 4.91)% versus (28.01 +/- 6.31)%], between child I and child II or more than II [3 year (60.68 +/- 3.68)% versus (49.88 +/- 4.13)%; 5 year (50.99 +/- 5.10)% versus (36.39 +/- 7.58)%], and between single segmentectomy of the liver and two or more than two segmentectomy [3 year (68.65 +/- 4.95)% versus (49.88 +/- 4.13)%; 5 year (65.38 +/- 5.69)% versus (37.98 +/- 5.70)%].

CONCLUSIONSSmall liver cancer, single-nodule, good hepatic function and minor resection were important factors to prolong survival further.
