ABSTRACT
Objective To investigate the effects of notoginseng and guiding medicinals mediated notoginseng for improving the renal inter stitial fibrosis in rats with chronic kidney-disease(CKD)by regulating TGF-β signaling pathway.Methods A total of 100 male SD rats were randomly divided into five groups:normal group(NOR,n =20),model group(CKD,n =20),radix notogin-seng group(RN,n =20),radix notoginseng plus platycodi group (RNP) and radix notoginseng plus cinnamon group (RNC,n =20).Except for the NOR group,the CKD rat model in other groups was established by adenine gavage.After modeling,the NOR group and CKD group were given the same volume of normal saline by gavage,while the group RN,RNP and RNC were given corresponding drugs by gavage,for 4 weeks.After 4 weeks,the rats in each group were sacrificed for collecting serum and detecting the renal function(serum Scr,BUN),the renal tissues were taken for conducting HE and Masson staining.Then the renal tissue pathological damage severity was observed.The expressions of FN and LN in kidney tissue were detected by immunohistochemistry and the expressions of TGF-[β,α-SMA were detected by Western blot method.Results Compared with the NOR group,the model group exhibited the renal dysfunction(P＜0.01),renal interstitial severe fibrosis manifestation and increased collagen deposition(P＜0.05),and the expression of kidney tissues α-SMA(P＜0.01),TGF-β(P＜0.01),FN and LN were significantly increased.Compared with the model group,the renal function in various treatment groups was improved,Scr(P＜0.01)and BUN(P＜0.01)were significantly decreased,the renal interstitial fibrosis degree was reduced,collagen desposition was decreased(P＜0.05),renal tissue α-SMA(P＜ 0.05),TGF-β(P＜0.05),FN and LN expression were reduced to some extent,in which the effect of RNC group was stronger than that of the RN group and RNP group.Conclusion Notoginseng and guiding medicinals mediated notoginseng can retard the progression of renal interstitial fibrosis caused by adenine in CKD rat in varying degrees,its mechanism maybe reduce the expression of TGF-β protein.
ABSTRACT
Objeetive To explore the effects of renal artery calcification on the progression of diabetic nephropathy (DN),the activation and its role of bone morphogenetic protein 2(BMP2) signal pathway in renal artery of rats.Methods Sixty male SD rats were randomly divided into control group(CON group),DN group and DN with vascular calcification group (DN+VDN group).Rats of group DN and DN + VDN were fed with high sugar and fat diet and injected with streptozocin (STZ) into abdominal cavity to induce diabetes.After diabetic models were successfully made,rats of group DN+ VDN were treated by vitamin D3 plus nicotine.The rats were sacrificed at 8th,12th and 16th week respectively and the levels of renal function,blood glucose and 24 h urinary protein (24-h Upro) were measured.The pathologic changes to the renal artery were observed by yon-Kossa staining and the calcium content was detected by calcium assay kit.The pathologic changes to the kidney were observed by HE.Immunohistochemistry was applied to detect the protein expression of BMP2/Smad1/Runx2/ Osterix signal pathway in the renal artery and real-time PCR were applied to detect the mRNA expression levels of BMP2 and Runx2.Results The calcium content and the deposition of black granules in DN group were significantly higher than those in group CON and lower than DN + VDN group at each time point (P ＜ 0.05).The renal function indices in group DN and group DN+VDN were gradually increased in 8th,12th and 16th weeks,and were higher than those in group CON (P ＜ 0.05).Compared with that in DN group,although the level of BUN,Scr,Cys C and 24-h Upro in DN+VDN group rats were higher at different time point,the level of Cys C at each time point and the level of 24-h Upro in the 16th week showed significant differences (P ＜ 0.05).The pathological damages of the kidney in group DN and DN+VDN showed a continual worsening trend and the pathological changes of the kidney in group DN+VDN were more serious than those in group DN.Furthermore,the levels of BMP2/Smad1/Runx2/Osterix signal protein and BMP2,Runx2 mRNA in DN rats were higher than those in CON group,lower than DN+VDN group at each time point (P ＜ 0.05).Correlation analysis demonstrated that calcium content was positively correlated with serum BUN,Scr,Cys C,24-h Upro and the expression of BMP2,Runx2 mRNA (r=0.835,0.705,0.829,0.897,0.641,0.683,P ＜ 0.01,respectively).Conclusion Renal artery calcification may participate in and promote the progression of DN,and the BMP2 signal pathway may be an important regulating factor in DN with renal artery calcification.
ABSTRACT
Objective To observe the effects of glucagon like peptide-1 (GLP-1) analogues liraglutide on expressions of nitric oxide synthase (NOS) and cyclo-oxygen-ase (COX)2 in renal medulla of type 2 diabetes rats, and the mechanism of its lowering blood pressure and promoting excretion of water and salt in kidney. Methods Type 2 diabetes model rats were generated by high-fat and high-sugar feeding for 8 weeks followed by intraperitoneal injection of streptozotocin (STZ). Subse?quently, eighteen type 2 diabetes rats were divided into two groups: liraglutide treatment group (DMT) and diabetes group (DM). Twelve normal rats were divided into two groups: liraglutide treatment wild type group (WTT) and wild type group (WT). DMT and WTT groups were given liraglutide (200μg/kg) by subcutaneous injection, DM and WT groups were given equivalent normal saline by the same way. The levels of blood glucose and blood pressure were detected at 0, 2, 4 and 6 weeks after treatment in groups of rats. Samples of urine were collected for detecting ion concentrations (K+, Na+and Cl-) af?ter treatment for six weeks. Rats were sacrificed and blood samples were collected for detecting ion concentrations (K+, Na+and Cl-). The expression levels of NOS and COX2 mRNA and protein in renal medulla were detected by real-time PCR and Western blot assay. Results After treating with liraglutide, the values of blood glucose (F=5.933, P sure (F=22.070, P<0.05) were gradually decreased in DMT group. After treatment with liraglutide for 6 weeks, the values of blood glucose (mmol/L:12.78 ± 3.82 vs. 18.75 ± 1.68) and blood pressure (mmHg:119.98 ± 4.43 vs. 136.42 ± 4.48) were signifi?cantly decreased (P<0.05) in DMT group than those of DM group (P<0.05). There were no significant differences in the concentrations of K+, Na+and Cl-between the two groups. There were higher levels of K+(mmol/L:46.55 ± 6.43 vs. 33.13 ± 9.71), Na+(mmol/L:56.33±8.83 vs. 41.20±7.25) and Cl-(mmol/L:159.81±25.06 vs. 71.44±12.99) in urine in DMT group than those of DM group (P<0.05). The mRNA levels and protein expressions of NOS and COX2 in renal medulla were significant?ly increased in DMT group than those of DM group (P<0.05). Conclusion GLP-1 analogues liraglutide may enhance the expression of COX2 by increasing the expression of NOS to excrete water and salt, and decrease blood pressure.

ABSTRACT
The actual efficacy of acupuncture on cerebral infarction was explored in clinical practice. The retro spective cohort study was adopted to investigate 344 cases via inpatient's medical cases. According to whether acupuncture was received or not, an acupuncture group (207 cases) and a non-acupuncture group (137 cases) were divided. The matching method, regression method and weighting method of propensity score (PS) were adopted, and the efficacy on muscle strength was taken as effect index so that the specific impacts of acupuncture were ex plored on the muscle strength in the patients of cerebral infarction. Before matching, COX regression model and Logistic regression model were used. And PS hierarchical regression, PS inverse probability weighting method (IPTW) and PS standardized mortality weighting method (SMRW) were applied to the analysis on the relationship between the muscle strengthen changes and the total effective rate in the two groups. It was found that the efficacy in the acupuncture group was better than that in the non-acupuncture group, indicating the significant difference (P<0.05). Meanwhile, the rehabilitation therapy also brought the obvious impacts on the efficacy evaluation (OR=2.737, P=0.0055). After PS matching, the Logistic regression model was used to analyze whether acupuncture or rehabilitation therapy impacted the total effective rate of muscle strength. The results showed that the efficacy was impacted apparently with the rehabilitation therapy involved (OR=2.930, P=0.0247). Without the rehabilitation effect considered, the efficacy in the acupuncture group was better potentially than that in the non-acupuncture group, but without significant difference (OR=2. 235, P=0,058 7). All of these indicate that on the basis of routine treatment, without the effect of rehabilitation therapy considered, acupuncture improves in tenden cy of the muscle strength of the patients with cerebral infarction. However, it is expected to increase the study medical cases for further verification.

The IgA1 proteases are a group of proteolytic enzymes, which are produced by pathogenic bacteria that infect and colonize mucosal surfaces. This group of proteolytic enzymes was found to cleave specific peptide bonds within the sequence TPPTPSPSTPPTPSPS (T, P and S are threonine, proline and serine residues, respectively) found in the hinge region of human IgA1. Several findings support the role of IgA1 protease, for example, its ability to cleave human LAMP1 (hLAMP1), TNF-RII, the CD8 molecule of T lymphocytes and granulocyte-macrophage colony-stimulating factor (GM-CSF), synaptobrevin II, hormone human chorionic gonadotropin, and its ability to exhibit important immunomodulatory properties, etc. , in particular the induction of proinflammatory cytokines. The IgA1 proteases have been found to instigate part of the T cell inflammatory response, especially to stimulate the release of cytokines such as tumour necrosis factor alpha (TNF-alpha), interleukin-1beta (IL-1beta), interleukin-6 (IL-6), and interleukin-8 (IL-8). All these suggest that this enzyme plays a significant role in pathogenesis. There are many other researches to explore new biological treatments of diseases using the biological characteristics of IgA1 protease.

IgA nephropathy is the most common form of primary glomerulonephritis which mainly accounts for the development of end-stage renal diseases. It is characterized by deposits of IgA1 in mesangium. The pathogenesis of IgA nephropathy is complicated. Moreover, there is a wide range of clinical features and variable histomorphologies in the diagnosed cases of IgA nephropathy. It was demonstrated that the galactose-deficient of IgA1 O-glycan chains led IgA1 to self-aggregation and eventual deposition in mesangium. Abnormality of glycosyltransferases, genetic mutation and immunologic disorder were involved in the aberrant glycosylation of IgA1 which was recognized as the key etiopathogenisis of IgA nephropathy. However, the exact source and the pathogenic mechanism of aberrantly glycosylated IgA1 remain obscure. The further studies on aberrant O-glycosylation of IgA1 would contribute to the understanding of IgA nephropathy and provide new therapeutical strategy.

This study sought to assess the effect of Ginsenoside Rg1 on streptozocin-induced diabetic nephropathy in rats and to unveil the underlying mechanism. Diabetic nephropathy (DN) was induced by intraperitoneal injection of streptozocin (STZ). Eight weeks after drug administration, the rats from each group were sacrificed. Serum creatine (Scr) and 24 hours urine protein, cross reaction protein (CRP) and tumor necrosis factor-alpha (TNF-alpha) were measured at the end of the study. The histological changes of renal interstitial tissues were observed by periodic acid-Schiff staining (PAS). Immunohistochemical method was used to examine the expression levels of ectodermal dysplasia (ED-1). The mRNA of transforming growth factor-beta1 (TGF-beta1) was measured by real-time PCR (RT-PCR), and the protein expression of TGF-beta1 was surveyed by Enzyme-Linked Immunosorbent Assay (ELISA). The renal pathological changes in DN rats given ginsenoside Rg1 treatment were ameliorated, and the expression levels of 24 h urine protein, serum creatinine, CRP, TNF-alpha, ED-1 and TGF-beta1 were significantly lower than those in the diabetic nephropathy group (P < 0.05). So, we reach a conclusion that, in the experiment, Ginsenoside Rg1 obviously reduced TGF-beta1 expression and the already-mentioned inflammatory reaction factors in the renal tissues and improved the renal pathological changes in DN rats.

Objective To clarify whether the Cosmc gene down-regnhtion in lgA nephropathy (IgAN) patients is resulted from genetic disorders or external suppressions. Methods Forty IgAN patients, 16 non-IgAN glomerulonephritis patients and 21 healthy controls were enrolled in the study. Genomie DNA was extracted and then Cosmc gene was amplified and sequenced. Peripheral B lymphoeytes were isolated and cultured with RPMI-1640 alone or plus lipopolysaecharide (LPS). The Cosmc mRNA expression levels at baseline, after RPMI-1640 culture or RPMI-1640+LPS treatment were measured respectively by real-time RT-PCR. Results (1) Only 2 missense mutations and 2 silent mutations were detected in coding frame region of Cosine gene in 2 IgAN patients. (2) The baseline Cosmc gene expression level was significantly lower in IgAN patients (31% of that in healthy controls) than that in healthy controls. (3) Relative quantification PCR indicated that Cosmc mRNA expression level was significantly increased (219% of baseline) after RPMI-1640 culture, and treatment of LPS could strongly inhibit this effect. (4) The Cosmc gene expression of healthy control was not affected by RPMI-1640 or LPS. Conclusion It is not genetic disorders but external suppression to cause the down-regulation of Cosmc gene mRNA expression in IgAN.
ABSTRACT
BACKGROUND: Pathogenesy of immunoglobulin A nephropathy (IgAN) is not clear up to now. Present research has verified that the key pathogenetic pathway is abnormalities of IgA1 molecular O-glycosylation induced by decrease of β1, 3-galactosyltranferase activity in IgA1 hinge region of IgAN patients. Prophase study by the authors supposed that the key of IgAN O-glycosylation abnormality might be due to the decrease of β1, 3-galactosyltranferase specific molecular protein chaperone Cosmc in B lymphocyte of peripheral blood in IgAN patients.OBJECTIVE: To measure DNA sequence of β1, 3-galactosyltranferase specific molecular chaperone in coding region of Cosmc gene in IgAN patients, and compared with the sequence of Gene Bank.DESIGN: Case-controlled observation.SETTING: Department of Nephrology, West China Hospital, Sichuan University.PARTICIPANTS: Totally 27 IgAN patients and 10 non-IgAN patients were recruited in Department of Nephrology of West China Hospital of Sichuan University from November 2005 to August 2006, and five normal controls were included in this study. All the subjects knew the fact and agreed to participate in the experiment.METHODS: The experiment was performed at the State Key Laboratory of Biotherapy of Sichuan University. 2 mL peripheral venous blood of all the samples were taken into heparin sodium anticoagulated tubes, from which total genomic DNA were extracted by phenol/chloroform precipitation method. Concentration of DNA was determined by ultraviolet spectrophotometer. The polymerase chain reaction (PCR) was used to amplify the coding region of β1, 3-galactosyltranferase specific molecular chaperone Cosmc gene in all the subjects and direct sequencing was done in PCR products of each subjects. The results of all the sequencing were compared with Gene Bank one by one.MAIN OUTCOME MEASURES: Amplification findings and sequencing of coding region of β1, 3-galactosyltranferase specific molecular chaperone Cosmc gene by PCR.RESULTS: ①Coding region of Cosmc gene located at 257-1 213, and amplified Cosmc gene was 1 247 bp. ②The sequence of Cosmc gene coding region was similar in IgAN patients, non-IgAN patients and normal controls, and no difference of gene sequence was noticed in all the result sequences as compared with the Gene Bank registered sequence.CONCLUSION: No abnormal sequence is found in coding region of Cosmc gene in IgAN patients, suggesting that this coding region probably is not associated with the abnormalities of IgA1 O-glycosylation in IgAN.
ABSTRACT
AIM: It has been proved that transforming growth factor-?1 (TGF-?1) has a close correlation with kidney fibrosis. This study investigated the effects of TGF-?1 on stromal cell-derived factor 1 (SDF-1) in rat renal tubular epithelial cells (NRK52E). METHODS: The experiment was carried out in the Division of Molecular Neurobiology, State Key Laboratory of Biotherapy, Sichuan University from March 2006 to May 2007. ①Rat renal tubular epithelial cells (NRK-52E, Monash Medical Center, Australia) were divided into normal control group, which were not treated with TGF-?1 (Cytola), and experimental group, which were subdivided into time-dependent groups: NRK-52E cells were incubated with TGF-?1 at the same concentration (2 ?g/L) for 6, 12, and 24 hours, and dose-dependent groups: NRK-52E cells were treated with TGF-?1 at different concentrations (2, 5, and 10 ?g/L) for 24 hours. ②The semi-quantitative calculation of SDF-1 protein expression in the cells treated with TGF-?1 at the concentration of 2 ?g/L for different time was accessed by immunocytochemistry to find the best time point. Then the variances of the mRNA and protein expression level in cells treated with TGF-?1 at different concentrations for 24 hours were detected by RT-PCR and Western-Blotting. RESULTS: ①The protein expression level of SDF-1 in NRK-52E cells treated with TGF-?1 for 12 and 24 hours was higher than for 0 hour (P 0.05). This indicated the SDF-1 expression reached a flat stage, and 24 hour was the bets time to study the dose dependence. ②Both the mRNA and protein expression level analyses demonstrated that the expression of SDF-1 in NRK-52E cells treated with 2 ?g/L TGF-?1 for 24 hours was significantly higher than that in normal control group (P

ABSTRACT
CTGF, a member of the CCN family of immediate early genes, is a recently discovered profibrotic growth factor, which is involved in many pathophysiologic procedures. CTGF acts as a downstream effector of TGF-? acting on interstitial cells to enhance the progression of fibrotic renal diseases. It has been shown that CTGF gene expression can be induced or blocked by some kinds of cytokine and drugs. It is an interesting candidate target for future intervention strategies of renal interstitial fibrosis. [
