BACKGROUND:At present,osteoarthritis has become a major disease affecting the quality of life of the elderly,and the therapeutic effect is poor,often focusing on preventing the disease process,and the pathogenesis of osteoarthritis is still not fully understood.Bioinformatics analysis was carried out to explore the main pathogenesis of osteoarthritis and related mechanisms of gene coding regulation. OBJECTIVE:To screen core differential genes with a major role in osteoarthritis by gene expression profiling. METHODS:Datasets were downloaded from the Gene Expression Omnibus(GEO):GSE114007,GSE117999,and GSE129147.Differential genes in the GSE114007 and GSE117999 data collections were screened using R software,performing differential genes to weighted gene co-expression network analysis.The module genes most relevant to osteoarthritis were selected to perform protein interaction analysis.Candidate core genes were selected using the cytocape software.The candidate core genes were subsequently subjected to least absolute shrinkage and selection operator regression and COX analysis to identify the core genes with a key role in osteoarthritis.The accuracy of the core genes was validated using an external dataset,GSE129147. RESULTS AND CONCLUSION:(1)A total of 477 differential genes were identified,265 differential genes associated with osteoarthritis were obtained by weighted gene co-expression network analysis,and 8 candidate core genes were identified.The least absolute shrinkage and selection operator regression analysis finally yielded a differential gene ASPM with core value that was externally validated.(2)It is concluded that abnormal gene ASPM expression screened by bioinformatics plays a key central role in osteoarthritis.

Objective: To investigate the regional differences in the incidence of urothelial carcinoma among kidney transplant recipients between northern and southern China,so as to provide reference for early diagnosis of this disease. Methods: A comprehensive search was conducted across multiple databases,including CNKI,Wanfang,CBM,and PubMed,using the keywords “kidney transplantation” and “tumor” to collect clinical data from qualified kidney transplant centers.The latest and most complete literature data published by 17 transplant centers in northern China and 14 in southern China were included.Statistical analyses were performed to compare the incidence of post-transplant urothelial carcinoma and non-urothelial malignancies. Results: A total of 37 475 kidney transplant recipients were included,among whom 837 (2.23%) developed post-transplant malignancies,including urothelial carcinoma (366/837,43.73%),non-urothelial carcinoma (444/837,53.05%),and malignancies with unspecified pathology (27/837,3.23%).The incidence of malignancies was significantly higher in northern China than in southern China [(2.82±1.39)% vs. (1.67±0.83)%,P=0.011],with a particularly pronounced difference in the incidence of urothelial carcinoma [(1.68±1.12)% vs. (0.32±0.32)%,P<0.001].No significant difference was observed in the incidence of non-urothelial carcinoma between the two regions [(1.11±0.56)% vs. (1.35±0.65)%,P=0.279].Additionally,female transplant recipients exhibited a higher incidence of malignancies than males in both regions (southern China:2.38% vs. 1.80%; northern China:8.93% vs. 2.52%). Conclusion: The incidence of urothelial carcinoma following kidney transplantation is significantly higher in northern China than in southern China,underscoring the importance of implementing regular tumor screening for kidney transplant recipients,particularly for female patients in northern China,to facilitate early diagnosis and timely intervention.

OBJECTIVES:
The core pathology of osteoporosis lies in bone resorption exceeding bone formation; thus, promoting osteogenesis is a key therapeutic strategy. The osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) forms the biological basis of bone formation. Astragaloside IV (A-IV), a major active component of Astragalus membranaceus, is known to enhance osteogenesis, but its precise molecular mechanisms remain unclear. This study aims to investigate the effects of A-IV on the proliferation and osteogenic differentiation of BMSCs from osteoporotic rats and to elucidate its molecular mechanism through the regulation of microRNA-21 (miR-21) and Notch2 expression.
METHODS:
After 1 week of adaptive feeding, mature female SD rats were randomly divided into a sham-operated (Sham) group (n=4) and an ovariectomized (OVX) group (n=8) to establish an osteoporosis model. Twelve weeks after surgery, BMSCs were isolated from femoral bone marrow and cultured. Cells were divided into a S-BMSCs group (from Sham), an O-BMSCs group (from OVX), and an A-BMSCs group (from OVX-derived BMSCs treated with A-IV). S-BMSCs and O-BMSCs were induced for osteogenic differentiation using osteogenic induction medium, whereas A-BMSCs were treated with A-IV before induction. Flow cytometry was used to identify mesenchymal stem cell surface markers (CD29) and hematopoietic stem cell marker (CD34) to confirm BMSC characteristics. Cell proliferation was assessed using the methyl thiazolyl tetrazolium (MTT) assay. Alizarin red staining was performed to quantify calcium nodule formation, and alkaline phosphatase (ALP) activity assays were used to evaluate osteogenic differentiation. Real-time reverse transcription PCR (real-time RT-PCR) was used to detect changes in osteogenic-related genes, runt-related transcription factor 2 (Runx2) and osteopontin (OPN), as well as miR-21 expression. Western blotting was performed to assess Runx2, OPN, and Notch2 protein expression.
RESULTS:
Flow cytometry confirmed that O-BMSCs retained the phenotypic characteristics of mesenchymal stem cells. A-IV significantly enhanced the proliferation of BMSCs from osteoporotic rats (P<0.05), increased ALP activity, and upregulated the mRNA and protein expression of Runx2 and OPN (P<0.05). Bioinformatic and experimental analyses demonstrated that miR-21 directly targeted Notch2. A-IV treatment increased miR-21 expression while suppressing Notch2 protein expression and inhibiting activation of the Notch signaling pathway (P<0.05).
CONCLUSIONS
Astragaloside IV promotes the osteogenic differentiation of BMSCs derived from osteoporotic rats by upregulating miR-21 expression and inhibiting the key Notch signaling protein Notch2, thereby relieving the Notch2-mediated suppression of osteogenesis.

OBJECTIVE:
Xuebijing injection has been recommended as a therapeutic approach for individuals with severe and critical COVID-19. This study aims to explore the correlation of neutrophil to lymphocyte platelet ratio (NLPR) with the severity and prognosis of COVID-19, and the effect of XBJ on the prognosis of patients with COVID-19 in different inflammatory states.
METHODS:
This was a retrospective study conducted at Wuhan Union Hospital in China. COVID-19 patients admitted between November 1, 2022 and February 1, 2023 were included. In predicting prognosis for individuals with COVID-19, new inflammatory indicators were used, and their prognostic value was assessed by using Cox regression models and receiver operating characteristic curves. Furthermore, a calculation was made to determine the cutoff value for NLPR. Relative risk and Cox regression models were used to examine the effects of Xuebijing injection on prognosis in patient cohorts that had been stratified by the NLPR cutoff.
RESULTS:
This research included 455 participants with COVID-19, with a mean age of 72 years. Several inflammatory indicators were found to be strongly correlated with prognosis, and NLPR shows the greatest predictive power. Patients with NLPR > 3.29 exhibited a mortality rate of 17.3%, which was 6.2 times higher than in patients with NLPR ≤ 3.29. Importantly, providing Xuebijing injection to patients with NLPR > 3.29 was associated with a lower risk of 60-day all-cause mortality. However, there was no discernible improvement in survival among patients with NLPR ≤ 3.29 who received Xuebijing injection.
CONCLUSION
NLPR is the most reliable inflammatory marker for predicting prognosis among individuals with COVID-19, and can accurately identify individuals who may benefit from Xuebijing injection.

Collagen, a vital matrix protein for various tissue and functions in animals, is widely applied in biomaterials. In type Ⅰ collagen, missense mutations of glycine (Gly) in the Gly-Xaa-Yaa triplet of the triple helix are a major cause of osteogenesis imperfecta (OI). Clinical manifestations exhibit marked heterogeneity, spanning a broad disease spectrum from mild skeletal fragility (Type Ⅰ) to severe limb deformities (Type Ⅲ) and perinatal lethal forms (Type Ⅱ). This study utilized recombinant collagen as a model to further elucidate whether Gly→Ala/Val mutations at the N-terminus of the integrin-binding sequence GFPGER affect collagen structure and function, and to explore the underlying mechanisms by which missense mutations impact the biological function of collagen. By introducing Ala and Val substitutions at seven Gly positions N-terminal to the GFPGER sequence, we systematically assessed the effects of these amino acid replacements on the triple-helical structure, thermal stability, integrin-binding ability, and cell adhesion of recombinant collagen. All constructs formed a stable triple-helix structure, with slightly compromised thermal stability. Gly→Val substitutions increased the susceptibility of recombinant collagen to trypsin, which suggested local conformational perturbations in the triple helix. In addition, Gly→Val substitutions significantly reduced the integrin-binding affinity and decreased HT1080 cell adhesion, with the effects stronger than Gly→Ala substitutions. Compared with Gly→Ala substitutions, substitution of Gly with the larger residue Val had enhanced negative effects on the structure and function of recombinant collagen. These findings provide new insights into the molecular mechanisms of osteogenesis imperfecta and offer theoretical references and experimental foundations for the design of collagen sequences and the development of collagen-based biomaterials.

Objective The purpose of this study was to investigate the bacterial communities of biting midges and ticks collected from three sites in the Poyang Lake area,namely,Qunlu Practice Base,Peach Blossom Garden,and Huangtong Animal Husbandry,and whether vectors carry any bacterial pathogens that may cause diseases to humans,to provide scientific basis for prospective pathogen discovery and disease prevention and control. Methods Using a metataxonomics approach in concert with full-length 16S rRNA gene sequencing and operational phylogenetic unit(OPU)analysis,we characterized the species-level microbial community structure of two important vector species,biting midges and ticks,including 33 arthropod samples comprising 3,885 individuals,collected around Poyang Lake. Results A total of 662 OPUs were classified in biting midges,including 195 known species and 373 potentially new species,and 618 OPUs were classified in ticks,including 217 known species and 326 potentially new species.Surprisingly,OPUs with potentially pathogenicity were detected in both arthropod vectors,with 66 known species of biting midges reported to carry potential pathogens,including Asaia lannensis and Rickettsia bellii,compared to 50 in ticks,such as Acinetobacter lwoffii and Staphylococcus sciuri.We found that Proteobacteria was the most dominant group in both midges and ticks.Furthermore,the outcomes demonstrated that the microbiota of midges and ticks tend to be governed by a few highly abundant bacteria.Pantoea sp7 was predominant in biting midges,while Coxiella sp1 was enriched in ticks.Meanwhile,Coxiella spp.,which may be essential for the survival of Haemaphysalis longicornis Neumann,were detected in all tick samples.The identification of dominant species and pathogens of biting midges and ticks in this study serves to broaden our knowledge associated to microbes of arthropod vectors. Conclusion Biting midges and ticks carry large numbers of known and potentially novel bacteria,and carry a wide range of potentially pathogenic bacteria,which may pose a risk of infection to humans and animals.The microbial communities of midges and ticks tend to be dominated by a few highly abundant bacteria.

Objective:To explore the incidence and mortality of digestive system cancers, and the trend of the disease burden attributed to different risk factors in population in China.Methods:Data were obtained from the GLOBOCAN 2020 and the Global Burden of Disease Study in 2019 databases and only the data from the Chinese population were included. Using Excel 2019 and R 4.2.1 software, indicators including age-standardized incidence rate (ASIR), age-standardized mortality rate (ASMR), age-standardized disability-adjusted life year (DALY) rate and its rate of change were used to illustrate the disease burden of digestive system cancers attributed to different factors and their trends.Results:In 2020, the ASIR of digestive system cancers in China was 83.00/100 000, and the ASMR was 63.80/100 000. The numbers of digestive system cancer cases and deaths increased with age, and more cases and deaths occurred in men than in women in all age groups. The age-standardized DALY rate of esophageal cancer, gastric cancer and liver cancers showed decreasing trends in China from 1990 to 2019 (rate of change: -45.26%, -46.87%, and -65.63%, respectively), whereas the age-standardized DALY rate of pancreatic cancer, colorectal cancer and gallbladder and biliary tract cancer showed increasing trends (rate of change: 67.61%, 30.52%, and 7.21%, respectively). The trend of the mortality rate was consistent with the DALY rate. Compared with the age-standardized DALY rate attributed to behavioral factors, the annual proportion of the age-standardized DALY rate attributed to metabolic factors to the total age-standardized DALY rate of esophageal cancer, liver cancer, pancreatic cancer, and colorectal cancer increased from 1990 to 2019. There was no significant change in the rank of age-standardized DALY rate of gastric cancer, liver cancer, pancreatic cancer, and gallbladder and biliary tract cancer attributed to different risk factors in China from 1990 to 2019, but the rank of certain attributed risk factors for the age-standardized DALY rate of esophageal cancer and colorectal cancer moved ahead (esophageal cancer: high BMI; colorectal cancer: low milk intake, and low whole-grain intake).Conclusions:The incidence and mortality of digestive system cancers was serious in China in 2020, and the annual proportion of the disease burden of digestive system cancers attributed to metabolic factors increased from 1990 to 2019. The rank of attributed risk factors for several digestive system cancers changed significantly.

Objective To investigate the hemodynamic effects of enhanced external counterpulsation(EECP)on cerebral arteries with different stenoses.Methods Zero-dimensional/three-dimensional multiscale hemodynamic models of cerebral arteries with different stenoses were constructed.Numerical simulations of the EECP hemodynamics were performed under different counterpulsation modes to quantify several hemodynamic indicators of the cerebral arteries.Among them,the mean time-averaged wall shear stress(TAWSS)downstream of the stenosis was in the range of 4-7 Pa,a low percentage of TAWSS risk area,and high narrow branch flow were considered to inhibit the development of atherosclerosis and create a good hemodynamic environment.Results For cerebral arteries with 50%,60%,70%,and 80%stenosis,the hemodynamic environment was optimal in counterpulsation mode when the moment of cuff deflation was 0.5,0.6,0.7,and 0.7 s within the cardiac cycle.Conclusions For 50%stenotic cerebral arteries,the counterpulsation mode with a deflation moment of 0.5 s should be selected.For 60%stenotic cerebral arteries,the counterpulsation mode with a deflation moment of 0.6 s should be selected.For 70%or 80%stenotic cerebral arteries,the counterpulsation mode with a deflation moment of 0.7 s should be selected.As stenosis of the cerebral arteries increases,the pressure duration should be prolonged.This study provides a theoretical reference for the EECP treatment strategy for patients with ischemic stroke with different stenoses.

ObjectiveTo explore the effects of modified Danggui Beimu Kushen pills on tumor growth and T-cell subsets in H22 hepatocellular carcinoma-bearing mice and to provide an experimental basis for the treatment of hepatocellular carcinoma with modified Danggui Beimu Kushen pills combined with immune checkpoint antibodies. MethodA H22 hepatocellular carcinoma-bearing mouse model was established. The modeled mice were randomized into model, cisplatin, low- (4 g·kg-1·d-1), medium- (8 g·kg-1·d-1), and high-dose (16 g·kg-1·d-1) modified Danggui Beimu Kushen pills groups. After continuous administration for 14 days, the mice were sacrificed on day 15. The tumor volume was measured on days 0, 4, 8, 12, 15 of drug administration. Tumors were weighed and thymus index and spleen index were calculated. Spleen lymphocytes were co-cultured with H22 hepatoma cells, and the tumor cell-killing rate was detected by the cell counting kit-8 (CCK-8). Real-time polymerase chain reaction was carried to determine the mRNA levels of programmed cell death protein-1 (PD-1) and lymphocyte activation gene-3 (LAG-3) in spleen and tumor tissues. The number of CD4+ and CD8+ T cells and the expression of PD-1 and LAG-3 were detected by immunohistochemistry (IHC). ResultOn day 8 of drug administration, tumor volumes in all treatment groups decreased compared with that in the model group. On day 15, both tumor volume and tumor weight were significantly lower in the treatment groups than in the model group (P<0.01), with the cisplatin group showing the most pronounced reduction. Compared with the model and cisplatin groups, medium- and high-dose modified Danggui Beimu Kushen pills increased the thymus index (P<0.01). Compared with the model group, all treatment groups showed increased spleen index (P<0.05, P<0.01), with the cisplatin group showing the most significant increase. Compared with the model and cisplatin groups, all the groups of modified Danggui Beimu Kushen pills demonstrated increased number of CD4+ and CD8+ T cells and tumor cell-killing rate in the spleen and tumor tissues (P<0.01) and down-regulated mRNA and protein levels of LAG-3 (P<0.05, P<0.01). The high-dose group of modified Danggui Beimu Kushen pills had lower mRNA level of PD-1 in the tumor tissue than the model and cisplatin groups (P<0.01). ConclusionModified Danggui Beimu Kushen pills may promote the proliferation and tumor microenvironment infiltration of CD4+ and CD8+ T cells in H22 tumor-bearing mice by down-regulating LAG-3 expression, thereby improving T-cell immune activity and inhibiting tumor growth. This study provides an experimental basis for the combination of modified Danggui Beimu Kushen pills and immune checkpoint antibodies in the treatment of hepatocellular carcinoma.
