Application of data mining algorithms in research on traditional Chinese medicine formula / 中国药房

In recent years， data mining algorithms have been widely employed in scientific research within the field of traditional Chinese medicine （TCM）. The data mining algorithms are used to effectively handle and analyze the complex data in TCM formulas， providing a rational explanation for the mechanism of action. This method has proven particularly useful in uncovering patterns of compatibility and frequent combinations of herbs in TCM， thereby enhancing the reliability and accuracy of clinical diagnosis， target screening， and the study of new drugs. This paper reviews and analyzes 147 papers on TCM formula research that utilize data mining algorithms. The results indicate that data mining algorithms play a unique advantage in six sub- areas， including the study on the mechanism of action in TCM formula， the dose-efficacy of TCM formulas， the identification of core drugs pairs/groups， mining the relationships among “formulas-drug-symptom”， the discovery of new formulas， and mining the compatibility law. Notably， association rules and clustering algorithms are the most representative.

Discussion on mechanism and experimental verification of Herba Hedyotidis in treating liver fibrosis based on network pharmacology / 国际中医中药杂志

Objective:To study the mechanism of Herba Hedyotidis against liver fibrosis based on network pharmacology. Methods:Based on TCMSP database and Uniprot database, the effective components and target genes of Herba Hedyotidis were screened. Target genes of liver fibrosis were screened by GeneCards and OMIM database, and the "disease-component-target" network map was constructed by Cytoscape 3.8.2 software. Protein interaction network was constructed by STRING database, and the Cytoscape 3.8.2 software was used to screen the core target out. The core targets were analyzed by gene ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment. Experimental verification was performed to the analysis results. A hepatic fibrosis model was established by intraperitioneal imjection of 40% carbon tetrachloride oil solution in rats that were then divided into the model control group and the Herba Hedyotidis group by randomized number table table, with 10 rats in each group. Ten normal rats were used as the normal control group. The Herba Hedyotidis group were injected 2.7 g/kg herb aqueous extract by intragastric administration, once a day, for 4 weeks; and the normal and model control group were given the same volume distilled water for gavage. The serum GPT, GOT, Alb and liver pathologic changes were observed. The serum expressions of IL-6, IL-1β and TGF-β1 were detected by ELISA. The expressions of PI3K, Akt, HIF-1α and VEGF were detected by Western blot. Results:5 effective components and 118 targets of Herba Hedyotidis in the treatment of hepatic fibrosis were obtained. Stigmasterol, β-sitosterol and quercetin were the most effective components with high moderate value. The moderate targets were VEGF, EGFR, HIF-1α and IL-6. The core genes of PPI network were HIF-1α, IL-6, etc. GO enrichment analysis showed that RNA transcription, protein binding and other processes may be affected. KEGG pathway enrichment analysis showed that significant enrichment pathways were cancer pathway, hepatitis B pathway, PI3K/Akt, HIF pathway and so on. Animal experimental results showed that compared with model group, liver histopathology was improved significantly, the content of GPT, GOT, IL-6, IL-1β and TGF-β1 decreased ( P<0.01), the content of Alb increased ( P<0.01), and the protein expressions of PI3K, Akt, HIF-1α and VEGF in liver tissue were down-regulated ( P<0.01). Conclusion:The Herba Hedyotidis exerts functions of anti-hepatic fibrosis through acting on the targets of VEGF, EGFR, HIF-1α and IL-6, regulating the PI3K/Akt, HIF-1 pathways, and has anti-inflammatory, anti-angiogenesis, anti-tumor and other biological functions.

Objective:To explore the characteristics and evolution trend of renal disease spectrum in Ningxia.Methods:The demographic, clinical manifestations and renal pathological examination results of patients who underwent renal biopsies in the General Hospital of Ningxia Medical University from August 1, 2008 to December 31, 2019 were collected and analyzed retrospectively. According to the time period of receiving renal biopsy, the patients were divided into 2008—2013 group and 2014—2019 group. The age and sex constituent, clinical manifestation, renal disease type, pathological types of primary and secondary glomerular disease and the main clinical manifestations of patients with diabetic nephropathy were compared between the two groups. The changing trend of renal disease spectrum in Ningxia from 2008 to 2019 was analyzed.Results:A total of 3 867 patients who underwent renal biopsies were enrolled in this study, with more males (53.71%, 2 077/3 867), and age of (39.59±14.05) years old. The most common clinical manifestation of patients receiving renal biopsies was nephrotic syndrome (36.33%, 1 405/3 867). Among them, primary glomerular diseases accounted for 78.79% (3047/3 867), followed by secondary glomerular diseases (18.57%, 718/3 867), renal tubulointerstitial diseases (1.45%, 56/3 867) and hereditary nephropathy (1.19%, 46/3 867). The most common primary glomerular disease was IgA nephropathy (44.60%, 1 359/3 047), followed by membranous nephropathy (30.75%, 937/3 047). The most common secondary glomerular disease was Henoch-Sch?nlein purpura nephritis (27.44%, 197/718), followed by lupus nephritis (25.07%, 180/718). Compared with the 2008—2013 group, the proportion of membranous nephropathy increased, the proportion of mesangial proliferative glomerulonephritis (non-IgA deposition) decreased (both P<0.001), the proportions of diabetic nephropathy and hypertensive renal damage increased, and the proportions of Henoch-Sch?nlein purpura nephritis and hepatitis B virus-associated glomerulonephritis decreased in 2014—2019 group (all P<0.01). Compared with the 2008—2013 group, the proportions of acute kidney injury, chronic renal failure, simple hematuria and urinary protein≤1.0 g/24 h increased in kidney biopsy patients in 2014—2019 group, while the proportion of nephrotic syndrome decreased (all P<0.05). Compared with the 2008—2013 group, the proportion of chronic renal failure in diabetic nephropathy patients increased during renal biopsy, and the proportion of albuminuria with hematuria decreased in 2014—2019 group (all P<0.05). Conclusions:Primary glomerular disease is the most common kidney disease in Ningxia. IgA nephropathy is the most common cause, and the proportion of membranous nephropathy is increasing year by year. Henoch-Sch?nlein purpura nephritis is the most common secondary glomerular disease, and the proportions of diabetic nephropathy and hypertensive renal damage are increasing year by year, suggesting that the screening of renal complications of metabolic diseases in Ningxia should be strengthened and pay more attention to the patients with mild abnormal urine test.

Objective:To explore the related risk factors of aortic arch calcification (AoAC) and the relationship between AoAC and long-term outcome in maintenance hemodialysis patients.Methods:The patients who underwent hemodialysis in the Blood Purification Center of Beijing Shijitan Hospital Affiliated to Capital Medical University from March to June 2015 were recruited. Calcification of the aortic arch was estimated with plain chest radiology. The patients were divided into AoAC group and no-AoAC group. Multivariate binary logistic regression was used to analyze the influencing factors of AoAC. Kaplan-Meier analysis and Cox regression model were used to examine the association between AoAC and adverse prognostic events (all-cause death and cardiovascular events).Results:There were 157 hemodialysis patients included in this study, with age of (62.63±15.05) years (30-90 years old) and 85 males (54.14%). The median follow-up time was 54(20, 54) months. There were 99 cases (63.06%) in AoAC group and 58 cases (36.94%) in no-AoAC group. The age, proportion of diabetes history, serum corrected calcium and triglyceride levels in AoAC group were higher than those in no-AoAC group (all P<0.05), while the proportion of using active vitamin D, serum albumin and intact parathyroid hormone level were lower than those in no-AoAC group (all P<0.05). Multivariate logistic regression analysis showed that older age ( OR=1.109, 95% CI 1.067-1.152, P<0.001), diabetes ( OR=4.110, 95% CI 1.551-10.890, P=0.004), longer dialysis duration ( OR=1.026, 95% CI 1.010-1.043, P=0.001), higher systolic pressure ( OR=1.039, 95% CI 1.012-1.067, P=0.005) and higher triglycerides levels ( OR=1.932, 95% CI 1.148-3.125, P=0.013) were the independent risk factors of AoAC, and higher hemoglobin was a protective factor ( OR=0.967, 95% CI 0.938-0.998, P=0.035) of AoAC. Sixty-three cases (63.64%) died, and 78 cases (78.79%) had cardiovascular events in AoAC group. Fourteen cases (24.14%) died, and 12 cases (20.69%) had cardiovascular events in no-AoAC group. Kaplan-Meier analysis showed higher incidence rate of all-cause death (Log-rank χ2=22.499, P<0.001) and cardiovascular events (Log-rank χ2=50.797, P<0.001) in patients with AoAC. Multivariate Cox regression analysis showed AoAC was the independent risk factor of all-cause death ( HR=2.003, 95% CI 1.039-3.859, P=0.038) and cardiovascular events ( HR=5.642, 95% CI 3.003-10.600, P<0.001). Conclusions:Older age, diabetes mellitus, longer dialysis duration, hypertension, higher triglyceride levels and lower hemoglobin are significantly associated with AoAC. AoAC is the independent risk factor of all-cause death and cardiovascular events in maintenance hemodialysis patients.

The correlation between serum levels of oxidative stress indicators and renal interstitial fibrosis in patients with IgA nephropathy / 中华肾脏病杂志

Objective To investigate the relationship between serum levels of oxidative stress indicators and the degree of renal interstitial fibrosis in patients with IgA nephropathy (IgAN).Methods Seventy eight patients with confirmed primary IgAN in General Hospital of Ningxia Medical University from January 2013 to December 2014 were enrolled.The patients were divided into T0 group (n=30),T1 group (n=26) and T2 group (n=22) according to the grade of tubular atrophy/interstitial fibrosis of Oxford pathological classification criteria for IgAN in 2009.Meanwhile,thirty cases of health examiner were enrolled as control subjects.The levels of serum malondialdehyde (MDA),superoxide dismutase (SOD),catalase (CAT) and glutathione peroxidase (GSH-Px) were detected by xanthine oxidase method,thiobarbituric acid spectrophotometry method,ultraviolet spectrophotometry method,chemical colorimetric method,respectively.The levels of serum advanced oxidation protein products (AOPPs),transforming growth factor beta 1 (TGF-β1),monocyte chemotactic protein 1 (MCP-1),transforming growth factor alpha (TGF-α),interleukin 6 (IL-6) and hypoxia inducible factor 1 alpha (HIF-1α) were detected by enzyme linked immunosorbent assay (ELISA) in all groups.Spearman correlation analysis was used to analyze the correlation between serum oxidative stress indicators and traditional risk factors of tubular atrophy/renal interstitial fibrosis.Multivariable linear regression analysis was used to analyze the correlation between oxidative stress indicators and degree of renal tubular atrophy/renal interstitial fibrosis.Results There were differences in serum levels of AOPPs,MDA,SOD,CAT and GSH-Px in IgAN patients with different degrees of renal interstitial fibrosis (all P ＜ 0.05).With the increase of renal interstitial fibrosis,the levels of AOPPs and MDA increased gradually,while the levels of SOD,CAT and GSH-Px decreased gradually.Serum AOPPs,MDA,SOD,CAT,GSH-Px concentration in IgAN patients were correlated with the mean arterial pressure (MAP),total blood protein (TP),albumin (Alb),Scr,uric acid (UA),24-hour urinary protein volume and estimated glomerular filtration rate (eGFR).Multivariate regression analysis showed that the AOPPs levels of blood were positively correlated with MAP,Scr,UA and 24-hour urinary protein (all P ＜ 0.01),and negatively correlated with TP,Alb,eGFR (all P ＜ 0.05).The serum levels of AOPPs and MDA in IgAN patients were positively correlated with the levels of TGF-β1,MCP-1,TGF-α,IL-6 and HIF-1α.The levels of SOD,CAT and GSH-Px were negatively correlated with the levels of TGF-β1,MCP-1,TGF-α,IL-6 and HIF-1α.Multivariate stepwise regression analysis showed that the degree of renal interstitial fibrosis in IgAN patients was positively correlated with serum AOPPs level (β=0.285,P=0.001),negatively correlated with CAT (β=-0.346,P ＜ 0.001),GSH-Px (β=-0.303,P ＜0.001).Conclusions The level of serum oxidative stress in IgAN patients is elevated and positively correlated with the degree of renal interstitial fibrosis,suggesting that oxidative stress may be involved in the occurrence and development of renal interstitial fibrosis.

Different prognosis in patients of peritoneal dialysis with high peritoneal solute transport / 中华全科医师杂志

To investigate association between prognosis of patients of peritoneal dialysis with their initial high peritoneal solute transport and complications. Two hundred and two patients with end-stage renal disease who began peritoneal dialysis during September 1,2006 to September 1, 2008 at Peking University Third Hospital, Beijing were recruited in the study. They were undergone peritoneal equilibration test within six weeks after initiating peritoneal dialysis, and their types of peritoneal solute transport, complications,nutrition status and outcomes were all recorded until August 31,2010. Their survival rate was estimated by Kaplan-Meier method. Compare to those with other types of solute transport, patients with high peritoneal solute transport showed higher proportion of complications ( P < 0. 05 ) during dialysis, but less ultrafiltration function ( P < 0. 05 ), worse nutrition status ( P < 0. 05 ) and lower cumulative survival rate ( P < 0. 01 ).Among patients with high peritoneal solute transport, cumulative survival rate in those with complication was lower than those without it ( P = 0. 031 ). Prognosis of patients with high peritoneal solute transport possibly varies with their complications in dialysis.

Interrelationship among urinary albumin elimination rate, serum adiponectin and blood glucose level in patients with type 2 diabetic nephropathy / 中华肾脏病杂志

Objective To investigate the interrelationship among urinary albumin elimination rate(UAER),serum adiponectin(ADPN)and blood glucose level in patients with type 2 diabetic nephropathy(DN). Methods A total of 89 type 2 diabetic patients and 30 healthy people as control were enrolled in the study.According to UAER,the diabetic patients were divided into three groups:normal group(35 cases,UAER＜30 mg/24 h),microalbuminura group (32 cases,UAER 30-300 mg/24 h)and macroalbuminura group(22 cases,UAER＞300 mg/24 h).Serum adiponectin was measured by ELISA.Body mass index (BMI),waist hip radio(WHR),fasting plasma glucose(FPG),2-hour plasma glucose(2hPG),glycated haemoglobin(HbAlc),blood lipid and UAER were measured routinely.Data were compared among groups. Results Serum adiponectin level was lower in diabetic patients than that in healthy control group(P＜0.05).Among diabetic patients.serum adiponectin of macroalbuminura group was significantly higher than that of normal and microalbuminura groups[(67.74±14.89)vs(39.36±13.92),(54.38±10.14)ng/L,P＜0.051.Multiple regression analysis showed 2hPG,HbAlc,BMI,disease course,UAER and DBP were closely associated with the level of serum adiponectin. Correlation analysis indicated serum adiponectin was positively correlated with age (r=0.255), disease course (r=0.405), HDL (r=0.501)and UAER (r=0.843); while negatively with HbAlc (r=-0.479), FPG (r=-0.436), 2hPG(r=-0.418),BMI (r=-0.479) and WHR (r= -0.531), all P＜0.01. Conclusions Serum adiponectin is positively correlated with UAER and negatively correlated with FPG. Blood glucose level is one of the main factors affecting serum adiponectin. Strict controlling of blood glucose level is beneficial to higher level of ADPN.
