Objective To observe the effect of effective monomer of Kangxianling prescription on renal function and extracellular matrix composition of 5/6 nephrectomy rats model, and provide basis for the screening of effective traditional Chinese medicine of anti-renal fibrosis. Methods Sixty SD rats were randomly divided into normal group, model group, chrysophanol group, salvianolate A group, oleanolic acid group and losartan group. The kidney fibrosis model was made by operation. Two months after intervented by correspong drugs, renal pathological changes of all groups were observed, the levels of renal function indexes were detected, and real-time PCR assay was used to detect laminin (LN), fibronectin (FN), type Ⅲ collagen (C-Ⅲ), type Ⅰ collagen (C-Ⅰ) mRNA expression in rat kidney tissue. Results SCr and BUN in model group increased significantly compared with the normal group (P<0.01). SCr and BUN in salvianolate A group decreased significantly compared with the model group (P<0.05, P<0.01). BUN in salvianolate A group decreased significantly compared with the losartan group (P<0.01). The expression of C- ,Ⅲ C-Ⅰand LN were reduced by effective monomer of Kangxianling prescription. Conclusion Effective monomer of Kangqianling prescription can inhibit renal fibrosis through reducing the expression of extracellular matrix components, thereby improve the renal function.

To explore a new way of constructing bioartificial renal tubule assist device (RAD) in vitro and its function of transporting sodium (Na(+)) and glucose and to evaluate the application of atomic force microscope in the RAD construction, rat renal tubular epithelial cell line NRK-52E was cultured in vitro, seeded onto the outer surfaces of hollow fibers in a bioreactor, and then cultured for two weeks to construct RAD. Bioreactor hollow fibers without NRK-52E cells were used as control. The morphologies of attached cells were observed with scanning electron microscope, and the junctions of cells and polysulfone membrane were observed with atomic force microscope. Transportation of Na(+) and glucose was measured. Oubaine and phlorizin were used to inhibit the transporting property. The results showed that NRK-52E cells and polysulfone membrane were closely linked, as observed under atomic force microscope. After exposure to oubaine and phlorizin, transporting rates of Na(+) and glucose were decreased significantly in the RAD group as compared with that in the control group (P<0.01). Furthermore, when the inhibitors were removed, transportation of Na(+) and glucose was restored. It is concluded that a new RAD was constructed successfully in vitro, and it is able to selectively transport Na(+) and glucose.

OBJECTIVETo investigate the therapeutic effect of Yiqi Huaju Recipe (YHR) combined with routine therapy on the blood pressure, the blood pressure variability and other cardiovascular risk factors in hypertension patients complicated with metabolic syndrome (MetS).
METHODSTotally 43 hypertension patients complicated with MetS were recruited in this study and randomly assigned to the treatment group (22 cases, treated with basic routine treatment +YHR) and the control group (21 cases, treated with basic routine treatment + placebo). The treatment course was 12 weeks. Detected were parameters such as 24-h ambulatory blood pressure monitoring (ABPM), body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), homeostatic model assessment for insulin resistance (HOMA-IR), fasting glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2 h PPG), fasting plasma insulin (FPI), serum lipid, etc.
RESULTSThe anthropometric parameters and plasma glucose levels (except HbAlc) were obviously lowered after treatment than before treatment in the treatment group (P < 0.01, P < 0.05). Besides, better effects were obtained in the WC, WHR, 2 h PPG, FPI and HOMA-IR (P < 0.05). The average blood pressure amplitude, the blood pressure variability, and blood pressure load at any time point were more obviously improved in the two groups after treatment than before treatment (P < 0.01, P < 0.05). Besides, partial indices were better in the treatment group than in the control group (P < 0.01, P < 0.05).
CONCLUSIONSYHR combined with routine therapy exhibited better effect on reducing the blood pressure amplitude, the blood pressure variability, and the blood pressure load in hypertension patients complicated with MetS. It could also effectively decrease the risk of other vascular disease.

Objective:To study the effect of Jianpi Qinghua Recipe ( JPQHR) on angiotensin II/NADPH oxidase pathway in 5/6 nephrectomized rat renal failure model and the underlying mechanisms.
Methods:The animals were divided into 4 groups:the sham-operated group, the renal failure group, the JPQHR-treated group and the losartan-treated group. After 60-days therapy, serum nitrogen and creatinine were measured. The expression of angiotensin II type 1 receptor (AT1) protein and the expression of p47phox mRNA in renal tissue was determined. SOD and MDA were also examined.
Results:Compared with the sham-operated group, the levels of SCr and serum BUN and the AT1 protein and p47phox mRNA expression in the renal failure group were significantly increased. hTe activities of SOD in renal tissue from the renal failure group was signiifcantly down-regulated while MDA was up-regulated (P<0.05). Compared with the renal failure group, the levels of SCr and serum BUN and the AT1 protein and p47phox mRNA expression in both JPQHR-treated group and losartan-treated group were signiifcantly decreased. hTe activities of SOD in renal tissue from JPQHR-treated group and losartan-treated group were signiifcantly up-regulated whereas the content of MDA were down-regulated (P<0.05). Compared with the losartan-treated group, the activities of SOD in renal tissue from the JPQHR-treated group was obviously increased (P<0.05), the decrease in AT1 protein and p47phox mRNA was more evident but not statistically different (P>0.05). The level of SCr and serum BUN and the content of MDA were also not statistically different (P>0.05).
Conclusion:hTrough decrease the expression of angiotensin II and NADPH oxidase, JPQHR can reduce the oxidative stress in chronic renal failure and delay the renal ifbrosis progression.

Objective To investigate the accumulation and maturation status of pulmonary conventional dendritic cells (cDCs) in the early phase of acute lung injury (ALI),and to explore the way of the inflammatory responses and lung injury modulated by cDCs in vivo.MethodsMale C57BL/6 mice were randomly ( random number) divided into the normal control group,6 h-ALI group and 24 h-ALI group.Murine model of ALI was made by intra-tracheal administration of lipopolysaccharide (LPS) and lung specimens were taken 6 h or 24 h later.The accumulation and maturation status of pulmonary cDCs were assessed by flow cytometry.IL-6 and TNF-α were quantified to evaluate the lung inflammation.Transcription factors T-bet/GATA-3 mRNA ratio was determined to estimate the balance between Th1/Th2 responses.IFN-γand IL-4 were quantified to evaluate Thl-specific and Th2-specific cytokine production respectively.Lung injury was estimated by lung wet weight/body weight ratio (LWW/BW) and histopathological assessment.Comparison between groups was performed using one -way ANOVA.ResultsCompared with normal control group,LPS challenge resulted in higher level of IL-6 and TNF-α,increased LWW/BW ratio and significant histopathological changes (P <0.01 ).The accumulation and maturation of pulmonary cDCs in 6 h-ALI group were significantly increased after LPS challenge (P <0.01 ),while the accumulation and maturation of pulmonary cDCs in 24 h-ALI group were significantly lower than that in 6 h-ALI group ( P <0.01 ).Compared with normal control group,the expression of T-bet mRNA in 24 h-ALI group was markedly enhanced ( P < 0.01 ) and the production of IFN-γ was increased as well ( P < 0.01 ).ConclusionsThe accumulation and maturation of pulmonary cDCs peaked within 24 h after LPS challenge,pulmonary cDCs may initiate and amplify acute lung inflammation of ALI by enhancing the Th1 immune response and ensuing cytokine production.
