There are many reversible factors in chronic renal failure,mainly including multifarious infections,insufficient effective blood volume,hypertension,heart failure,urinary obstruction,nephrotoxicity drugs and so on.Traditional Chinese medicine can exert the predominances of whole adjustment and treatment based on syndrome differentiation.After taking traditional Chinese medicine in time,many patients' renal function can recover in some extent.

OBJECTIVE: To explain the current situation of the study on Chinese herb nephropathy (CHN), clarify the concept of CHN and investigate the pathogenesis, also suggest the measures for the prevention and treatment of CHN.DATA SOURCES: Articles about kidney impairment induced by Chinese herbal medicine containing aristolochic acid (AA) published in English between January 1994 and April 2006 were searched in Pubmed database by using the keywords of "kidney impairment induced by Chinese herbal medicine containing aristolochic acid (AA), nephropathy induced by aristolochic acid (AA), Chinese herb nephropathy (CHN)". Other articles were collected by the specific name of journals and title of papers by retrieving VIP database.STUDY SELECTION: The original articles were checked primarily, those about kidney impairment induced by Chinese herbal medicine containing AA were selected, those obviously irrelevant ones were excluded, and the full-texts of the involved articles were searched manually.DATA EXTRACTION: Totally 86 articles were collected, 20 of them were involved, and the other 66 repetitive studies or reviews were excluded:DATA SYNTHESIS: At present, kidney impairment induced by Chinese herbal medicine has not attracted enough attentions in Chinese, and effective monitoring system should be established. The diagnosis and pathogenesis of nephropathy induced by AA are still unclear, and the prevention is the main treatment. Therefore, we should realize its harmfulness, and reinforce its basic and clinical researches.CONCLUSION: The main damage in kidney caused by AA focuses on the renal tubulointerstitial matrix. Renal glomerulus is rarely involved in the toxic process. Clinical manifestations also reflect the impairment of renal tubules and interstitium such as interstitial fibrosis. A more effective diagnosis monitoring and screening system should be set up in order to mesh the patients at the early stage. A more stringent method for classification of the species in fourstamen stephania root family will be established to avoid confusion and error. More valid therapeutic channels should investigate for its remedy.

OBJECTIVE: To investigate the effects of Shenshuning Recipe (SSNR) on gene expression of hepatocyte growth factor (HGF) in renal tissues in rats with glomerulosclerosis. METHODS: Glomerulosclerosis was induced in 42 rats by unilateral nephrectomy and intravenous injection of doxorubicin. Then these 42 rats were randomly divided into three groups: untreated group, SSNR-treated group and benazepril-treated group. Another eight rats were included into sham-operation group. The rats in the SSNR-treated group and the benazepril-treated group were fed SSNR or benazepril respectively for 8 weeks. The levels of 24 h urine protein (Upr), serum creatinine (Cr) and blood urea nitrogen (BUN) of rats in each group were examined. The renal morphological changes were observed under microscope, and the diameter of glomerular capillary, mesangial matrix and glomerulosclerosis index were analyzed by image analysis software. Reverse transcription-polymerase chain reaction (RT-PCR) method was used to detect the gene expression of HGF in the renal tissues. RESULTS: The levels of 24 h Upr, serum Cr and BUN in the untreated group were remarkably increased than those in the sham-operation group (P<0.01). The pathological morphological changes in the untreated group showed that the glomerulosclerosis was diffused around the renal tissue and the capillaries were shrunk. The expression level of mesangial matrix was up-regulated and the glomerulosclerosis index was 3.32+/-0.35. The expression level of HGF mRNA in the untreated group was obviously lower than that in the sham-operation group (P<0.05). The levels of 24 h Upr, serum Cr and BUN in the SSNR-treated group and the benazepril-treated group were remarkably decreased as compared with those in the untreated group, while the expression levels of HGF mRNA were both obviously higher than that in the untreated group (P<0.01). The pathological morphological changes in the SSNR-treated group and the benazepril-treated group were both alleviated. There was no significant difference in therapeutic effect between the SSNR-treated group and the benazepril-treated group. CONCLUSION: Shenshuning Recipe can up-regulate the expression of HGF mRNA, decrease the mesangial matrix, and improve the renal function, so that it may retard the development of glomerulosclerosis.

Objective To investigate the clinical efficiency of endoscopic pancreatic sphincterotomy ( EPS) combined with pancreatic duct stent for acute recurrent pancreatitis ( ARP ) caused by biliary microlithiasis. Methods A total of 71 patients were diagnosed as having ARP resulting from biliary microlithiasis from April 2005 to November 2016, and their clinical data were retrospectively analyzed. Patients were divided into two groups according to different endoscopic therapy, EPS ( n=34) and EST group (n=37), respectively. The rate of pancreatitis recurrence, post-ERCP pancreatitis (PEP) and biliary complications were compared by Chi-square test and the influencing factors of recurrence were evaluated by survival analysis. Results The follow-up time ranged from 2 to 108 months ( median 21. 5 months) in EPS group and ranged from 5 to 120 months ( median 39 months) in EST group. Twelve months after endoscopic therapy, 2 patients in EPS group and 5 in EST group suffered recurrent pancreatitis(χ2=0. 461, P=0. 497). Recurrence occurred in 13 patients in 60 months after endoscopic therapy, 4 patients in EPS group and 9 in EST group. Cox regression analysis indicated different endoscopic treatment ( RR=6. 808, 95%CI: 1. 389-33. 356, P=0. 018) and type 2 diabetes ( RR=0. 134, 95%CI:0. 029-0. 608, P=0. 009) were statistically significant factors. There were no significant difference in incidence of PEP (20. 6% in EPS group, 10. 8% in EST group,χ2=1. 294, P=0. 255) and biliary complications between two groups (11. 8% in EPS group, 24. 3% in EST group, χ2=1. 869, P=0. 172). Conclusion EPS combined with pancreatic stenting is effective for acute recurrent pancreatitis caused by microlithiasis. Type 2 diabetes may also lead to recurrence of acute pancreatitis.

Objective:To compare the changes of biliary microbiota after enteral extended biliary stents (EEBS) implantation with that of conventional plastic stents in animal experiment, and to preliminarily investigate its possible mechanism in preventing stents occlusion.Methods:A total of 12 healthy Bama minipigs were randomly assigned to the conventional plastic stent group ( n=6) and the EEBS group ( n=6) using simple random method. The bile samples of all pigs were collected before stents implantation and 4 weeks after stents placement. The biliary microbiota composition and diversity before and after different stents implantation were analyzed by 16S rRNA gene sequencing and compared. Results:No complications including acute cholangitis, perforation, bleeding, or death occurred in 12 pigs. Eight days after stents implantation, stents were out of bile duct in all pigs under endoscopy, while the bile samples were collected again for analysis. The main composition of biliary microbiota at the phylum level were Proteobacteria, Firmicutes and Bacteroidota. Alpha-diversities revealed the Shannon ( P=0.004) and Simpson index ( P=0.008) significantly decreased in the conventional stent group after stents placement, and Bata diversity analysis also showed a significant difference in microbial composition (Anosim: R=0.514 8, P=0.011). There was no significant difference in Observed species index ( P=0.095), Chao1 index ( P=0.136), Shannon index ( P=0.353), Simpson index ( P=0.227) or Bata diversity (Anosim: R=0.059 3, P=0.187) in the EEBS group before and after stents placement. LEfSe algorithm indicated Bacteroides_ fragilis and Proteobacteria- Gammaproteobacteria- Enterobacterales- Enterobacteriaceae- scherichia_ Shigella- Escherichia_ coli significantly increased in the conventional stent group, and Desulfobacterota- Desulfovibrionia- Desulfovibrionales- Desulfovibrionaceae- Bilophila significantly increased in the EEBS group after stents placement. Conclusion:The biliary microbiota change slightly after EEBS implantation in the short-term, and EEBS may prevent duodenobiliary reflux by prolonging the reflux path.

ObjectiveTo investigate the effect of total alkaloids of Corydalis saxicola on a rat model of lipopolysaccharide（LPS）-induced depression， as well as the pharmacokinetic characteristics of 8 of its major components. MethodTwenty-four male SD rats were randomly divided into normal group， model group， fluoxetine group（10 mg·kg^-1） and total alkaloids of C. saxicola group（210 mg·kg^-1）， with 6 rats in each group. In addition to the normal group， the rats were injected intraperitoneally with LPS to establish the inflammation model of depression， and the drug administration was started 1 week after modeling， and the administration groups were gavaged according to the corresponding dose， and the normal and model groups were intragastric administration with equal volume of distilled water， and the administration was performed along with the modeling. After two weeks of continuous administration， the effect of total alkaloids of C. saxicola on the behavior of depressed rats were tested by sucrose preference， forced swimming and open field experiments， the levels of tumor necrosis factor-α（TNF-α）， interleukin（IL）-1β and IL-6 in serum of rats were determined by enzyme-linked immunosorbent assay（ELISA）， the histopathological changes of rat hippocampus were observed by hematoxylin-eosin（HE） staining. After the last administration， blood was collected from orbit according to the set time， and ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry（UPLC-QqQ-MS） was established to simultaneously detect the concentrations of dehydrocavidine， tetrahydropalmatine， coptisine， palmatine， jatrorrhizine， berberine， berberrubine and epiberberine in plasma， and drug-time curves were drawn. The pharmacokinetic parameters were analyzed by DAS 2.0 software. ResultCompared with the normal group， the model group exhibited a decrease in sucrose preference rate， total distance traveled in the open field， as well as an increase in swimming immobility time and serum inflammatory factor expression（P<0.01）. In contrast， compared with the model group， rats in each administration group showed an increase in sucrose preference rate and total distance traveled in the open field， a decrease in swimming immobility time， and a reduction in serum inflammatory factor expression（P<0.05， P<0.01）. Additionally， HE staining results revealed that neurons in the hippocampus of rats from the model group were characterized by loss， disorganization and residual vacuoles， whereas those from the total alkaloids of C.saxicola group displayed an increase in number with orderly arrangement and clear cytoplasm. Pharmacokinetic results showed that the time to peak（t_max） and half-life（t_1/2） of the 8 active ingredients were 0.19-2.06 h and 3.71-8.70 h after continuous administration of total alkaloids of C. saxicola. Among them， the area under the curve（AUC_0-∞） of tetrahydropalmatine was the highest and the t_1/2 was the shortest， and the AUC_0-∞ of coptisine， palmatine， jatrorrhizine， berberine， berberrubine and epiberberine were low. The curves of dehydrocavidine， coptisine， palmatine， berberine and epiberberine showed obvious double peak phenomenon. ConclusionTotal alkaloids of C. saxicola can improve the depression-like behavior of rats， inhibit the expression of inflammatory factors in serum， improve the pathological injury of hippocampus， and has the antidepressant effect. Meanwhile， the effective site is absorbed quickly and eliminated slowly in the depressed model rats， and the efficacy is maintained for a long time.
