Objective To observe the clinical therapeutic effects and evaluate the security of Huganjiexian decoction combined with conventional therapy on hepatic cirrhosis.MethodsBy the randomized and prospective study method,34 patients with liver cirrhosis were divided into experimental group and control group.The experimental group was treated with Huganjiexian decoction combined with conventional therapy while the control group was treated with conventional therapy alone.Patients in both groups were treated six months.At the beginning and 6 months after treatment,levels of alanine transaminase (ALT),aspartate transaminase (AST),albumin (ALB),albumin/globulin (A/G),total bilirubin (TBiL),blood urea nitrogen (BUN),serum creatinine (Scr) were determined.Results Levels ofALT、AST、TBiL decreased in both groups after being treated for six months,and the differences of downward trend of the experimental group were more significant than control group (F=36.63,40.31,38.65,P＜0.05).Levels ofALT、AST、TBiL of the experimental group were lower than those of control group significantly (F=8.67,7.62,4.36,P＜0.05 ).The A/G raised in both groups after treatment,and the upward trend of the experimental group was greatly different from that of control group (F=24.10,P＜0.05),the value of A/G of the experimental group was higher than that of control group (F=4.78,P＜0.05).The ALB raised in both groups after treatment,while the upward trend of the experimental group was no different from that of control group (F=0.89,P＞ 0.05).Thevalue of ALB had no significant changes in both groups (F=3.15,P＞0.05).Conclusion Huganjiexian decoction possessed therapeutic effect on hepatic cirrhosis,it had no obvious toxicity and side

Objective:To explore the correlation between fibular head height and varus knee osteoarthritis occurrence and severity.Methods:A retrospective analysis was performed on 618 participants (618 knees, 184 males and 434 females, mean age 61.12±10.98 years) who underwent standard weight-bearing full-leg radiographs and were diagnosed as non-knee osteoarthritis or varus knee osteoarthritis from January 2019 to June 2019. Knee osteoarthritis was diagnosed according to Kellgren-Lawrence grading: 0-I grades were diagnosed as non-osteoarthritis, II-IV grades were diagnosed as osteoarthritis. Joint line convergence angle (JLCA), medial proximal tibial angle (MPTA) and hip-knee-ankle angle were measured on X-rays to reflect varus deformity. The fibular head height was defined as the vertical distance from upper edge of fibular head to lateral tibial plateau. Patients were divided into 5 groups according to Kellgren-Lawrence grading. Differences of age, gender, height, weight, body mass index, varus deformity (JLCA, MPTA and hip-knee-ankle angle) between Kellgren-Lawrence 0-IV grades were compared. Ordinal logistic regression was performed to analyze the correlation between fibular head height and Kellgren-Lawrence grades. Pearson's correlation analysis was used for the correlation among fibular head height, JLCA, MPTA and hip-knee-ankle angle, and the main factor of JLCA, MPTA and hip-knee-ankle angle was extracted by factor analysis. Multiple linear regressions were used to analyze the correlation between fibular head height and varus deformity score.Results:There were 68, 66, 97, 98, 289 participants in Kellgren-Lawrence grades 0-IV respectively that was 134 participants were diagnosed as non-osteoarthritis and 484 participants were diagnosed as osteoarthritis. Fibular head height and MPTA showed a decreasing trend ( F=129.076, 24.875; P<0.001) while JLCA and hip-knee-ankle angle showed an increasing trend ( F=414.346, 105.996; P<0.001) with the increase in Kellgren-Lawrence grading. Age, body mass index and fibular head height are influencing factors of Kellgren-Lawrence grading with OR(95%CI) were 1.116(1.093, 1.141), 1.363(1.060, 1.754), 0.617(0.575, 0.662) . Fibular head height was negatively correlated with JLCA and hip-knee-ankle angle ( r=-0.641, -0.478; P<0.001) , respectively, and positively correlated with MPTA ( r=0.320, P<0.001). There were significant correlations between age, fibular head height and the varus deformity score ( β=0.274, -0.457; P<0.001). Conclusion:Fibular head height of patients with varus knee osteoarthritis is lower than that of non-osteoarthritis. In addition to age and body mass index, fibular head height is a risk factor for varus knee osteoarthritis occurrence. The smaller the fibular head height is, the more serious the osteoarthritis severity and varus deformity are.

Objective The aim of this study was to investigate the susceptibility and prognostic implications of the cyclin D1 gene(CCND1) G870A polymorphism to nasopharyngeal carcinomas (NPC) in Han population in Yunnan China. Methods Two hundred and forty one cases with NPC and 271 matched cancer-free controls were genotyped for the CCND1 G870A polymorphism by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) and sequencing. The adjusted odds ratios (OR) and 95% confidence intervals (CI) were calculated by using unconditional logistic regression model. Overall survival was assessed using univariate and multivariate analyses. Results Contrast with homozygous CCND1 G870G, A allele significantly increasing risk of NPC was associated with homozygous A870A (OR =4.79, 95% CI 2.77 - 8.28, P < 0.001) and heterozygous A870G (OR = 1.72, 95% CI 1.10 - 2.68, P = 0.017). The subjects at least having one CCND1 870A allele had OR of 2.40(95% CI 1.59 -3.63, P < 0.001). Furthermore, smoking may increase the risk of developing NPC interacting with CCND1 G870A polymorphism. Kaplan-Meier analysis and Cox regression analysis demonstrated that the five-year survival rate of subjects with A.A, AG and GG genotypo was 56.2%, 78.5% and 81.4% (AA vs GG, P=0.003; AA vs AG, P =0.012; AG vs GG, P =0.132), but not independent prognostic factor in NPC(P = 0.501). Conclusions The CCND1 870A allele is associated with the NPC in Han population in Yunnan China, meanwhile, showed a significant prognosis for those patients.

Objective:To explore the material basis and mechanism of Linggui Zhugan Decoction in treating hypertension and obesity by means of network pharmacology and molecular docking technique.Methods:The TCMSP was retrieved and the main active components and action targets of Linggui Zhugan Decoction were screened. The GeneCards, OMIM, TTD, DisGeNET and DrugBank databases were used to screen disease-related targets of hypertension and obesity. The Cytoscape 3.9.0 was used to draw Chinese materia medica-composition-intersection target-disease network diagram. The STRING 11.5 database was used to draw PPI network. The cytoNCA plug-in was used to screen core active components and targets. The bioenrichment analysis of GO and KEGG was carried out in the R4.1.2, and the Chinese materia medica-intersection target-path diagram was drawn, and the core active components and core targets were docked in PyMOL and AutoDockTools 1.5.7.Results:A total of 102 potentially active components and 62 intersection targets were obtained, and 8 active components and 7 core targets were screened. Enrichment analysis showed that the key targets were mainly enriched through the signaling pathways of fluid shear stress and atherosclerosis, lipid and atherosclerosis, and AGE-RAGE, which were involved in biological processes such as the response to nutritional levels and the regulation of small molecule metabolism. Molecular docking showed that there were 37 groups with addinity < -7 kcal/mol.Conclusion:The main active components of Linggui Zhugan Decoction are quercetin, kaempferol and naringenin, which may play a role in fluid shear stress and atherosclerosis pathway, lipid and atherosclerosis pathway and AGE-RAGE signal pathway through AKT1, EGFR, IL1B and other targets.

Age-associated changes in immune cells have been linked to an increased risk for infection. However, a global and detailed characterization of the changes that human circulating immune cells undergo with age is lacking. Here, we combined scRNA-seq, mass cytometry and scATAC-seq to compare immune cell types in peripheral blood collected from young and old subjects and patients with COVID-19. We found that the immune cell landscape was reprogrammed with age and was characterized by T cell polarization from naive and memory cells to effector, cytotoxic, exhausted and regulatory cells, along with increased late natural killer cells, age-associated B cells, inflammatory monocytes and age-associated dendritic cells. In addition, the expression of genes, which were implicated in coronavirus susceptibility, was upregulated in a cell subtype-specific manner with age. Notably, COVID-19 promoted age-induced immune cell polarization and gene expression related to inflammation and cellular senescence. Therefore, these findings suggest that a dysregulated immune system and increased gene expression associated with SARS-CoV-2 susceptibility may at least partially account for COVID-19 vulnerability in the elderly.
