Isolated alkaloids from Coptis chinensis Franch. The compounds were identified as berberine, columbamine, groenlandicine, jatrorrhizine, magnoflorine, corydaldine and ferulic acid methylester. Then measured their bitter degree based on the electronic tongue and evaluated the antibacterial. The results based on the Electronic Tongue showed that berberine, columbamine, groenlandicine and jatrorrhizine have higher bitter degree than magnoflorine and corydaldine. And they also appeared better antibacterial activity on E. coli and S. aureus. The correlation coefficients between bitter degree and the two bacteria antibacterial activity were 0.983 and 0.911. So there was close relationship between the bitter degree and antibacterial activity of bitter components. Thus, it is confirmed further that bitter components are the material foundation of medicinal effectiveness of bitter herbs.

Effects of traditional Chinese medicine salvianolate combined with alprostadil and reduced glutathione on delay of progression in patients with acute kidney injury has been confirmed, but the role of this combination therapy on the progression of chronic renal failure is uncertain.

OBJECTIVE: To evaluate the effect of integrated traditional Chinese and Western medicine therapy on the progression of acute renal failure in patients with chronic renal insufficiency. METHODS: Thirty-two patients with chronic renal insufficiency developed acute renal failure recently were treated with Chinese herbs and western drugs intravenously and clysterizing of Chinese herbs liquid for 30 minutes, and the treatment course was 14 days. Assessment of liver and renal function, blood routine, electrolytes and endogenous creatinine clearance rate (Ccr) was performed before and 2 weeks after the treatment. RESULTS: The levels of hemoglobin (HB), white blood cell count (WBC) and serum electrolytes showed no significant changes after the treatment. The levels of blood urea nitrogen (BUN) and serum creatinine (SCr) decreased, while the level of Ccr increased significantly (P<0.05) after the treatment. The total effective rate was 65.6%. CONCLUSION: The integrated traditional Chinese and Western medicine therapy can effectively delay the deterioration of renal function in patients with chronic renal insufficiency accompanied by acute renal failure.

Comparative analysis of characteristic of species and esterase-isoenzyme of isolates of Polyporus umbel-latus from different regions were processed. The results indicated that isolates of Jizhaoling ( Z) and Zhushiling (ZJ) have significant differences in characteristic, and enzymatic band types of the two species also have significant differences. The homology at genetics between the two isolates is 0% , and consanguinity between the two i-solates is the farthest.

BACKGROUND: This study aimed to investigate the prevalence rate of critical illness-related corticosteroid insufficiency (CIRCI) and the effect of low-dose glucocorticoid on prognosis of CIRCI in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). METHODS: Since January 2010 to December 2012, 385 patients, who met the criteria of AECOPD, were enrolled in the Intensive Care Unit (ICU) of the First People's Hospital and Municipal Central Hospital of Xiangtan City. The AECOPD patients complicated with CIRCI screened by an adrenalcorticotrophic hormone test within 12 hours after admission to ICU were divided into a treatment group (n=32) and a control group (n=31) for a prospective, randomized and controlled clinical trial. Hydrocortisone (150 mg/d) or normal saline was injected intravenously for 7 days. The patients were followed up for 28 days after injection. The endpoint included 28-day survival time, non-shock time, ICU stay and the period of non-mechanical ventilation. The markers of inflammation C-reactive protein, tumor necrosis factor-α, interleukin 6 and procalcitonin were measured at baseline and 7 days after treatment. The variables were analyzed by Student's t test, the non-parametric statistical test, the Chi-square test or the Kaplan-Meier method with SPSS18.0 statistic software. A P value <0.05 was considered statistically significant. RESULTS: Totally 63 patients were diagnosed with CIRCI by an adrenalcorticotrophic hormone test and the prevalence rate was 16.4％. The shock rate of the AECOPD patients complicated with CIRCI was higher than that of the AECOPD patients without CIRCI (23.8％ vs. 8.7％, P<0.01). Kaplan-Meier analysis revealed that the 28-day survival time of the treatment group was obviously longer than that of the control group (P<0.05). Compared with the control group, shock-free days within 28 days was longer in the treatment group (18.2±9.5 vs. 25.8±4.1, P<0.05). Treatment with low-dose glucocorticoid obviously decreased the markers of infection and inflammation (P<0.01), such as C-reactive protein (13.2±5.5 mg/L vs. 8.3±3.1 mg/L for the control group; 13.5±5.9 mg/L vs. 5.1±2.3 mg/L for the treatment group), tumor necrosis factor-α (26.1±16.2 g/L vs. 17.5±11.7 g/L for the control group; 25.0±14.8 g/L vs. 10.4±7.8 g/L for the treatment group) and procalcitonin (3.88 g/L vs. 2.03 g/L for the control group; 3.77 g/L vs. 1.26 g/L for the treatment group). Furthermore, the markers in the treatment group decreased more obviously than those in the control group (P<0.01). CONCLUSION: The prevalence rate of CIRCI was higher in the patients with AECOPD in the department of critical medicine, and low-dose glucocorticoid treatment for one week reduced the 28-day mortality, shock time and markers of infection and inflammation.

UNLABELLEDOBJECTIVE To observe the clinical efficacy by Qingying Huoxue Decoction (QHD) combined ursodeoxycholic acid (UDCA) in treating patients with early and mid-term primary biliary cirrhosis (PBC). METHODS Totally 78 patients were randomly assigned to the treatment group and the control group, 39 in each group. All patients received basic treatment and took UDCA (at the daily dose of 13-15 mg/kg). Patients in the treatment group took QHD, one dose per day. The treatment course for all was 6 weeks. Clinical efficacy, gamma-glutamyl transferase (γ-GGT), alkaline phospatase (ALP), TBIL, alanine aminotransferase (ALT), and aspartate transaminase (AST) were observed before and after treatment. RESULTS Totally 21 (53. 8%) patients obtained complete response in the treatment group, with statistical difference when compared with that of the control group (11 cases, 30. 8%). Levels of GGT, ALP, ALT, AST, and TBIL decreased in the two groups after treatment (P < 0.01). Levels of ALP, GGT, and TBIL were obviously lower in the treatment group than in the control group (P < 0.05).

CONCLUSIONSQHD combined UDCA in treating early and mid-term PBC patients was superior to the effect of using UDCA alone. It also could improve patients' liver function.

OBJECTIVETo evaluate the efficacy of cyclosporin A (CyA) therapy in 83 children with nephrotic syndrome of different pathological types.

METHODSEighty-three children enrolled in this study were all hospitalized children with idiopathic nephrotic syndrome, aged 3 to 14 yrs (average 8.3 yrs) and included 52 males and 31 females. There were 35 cases with steroid-dependent, 17 with steroid resistant and 26 with frequent relapses. CyA was given to each patient with dosage of 5 mg/(kg.d) during the corticosteroid was diminished. The renwal biopsy was performed in all patients before the administration of CyA. The duration of CyA therapy lasted for about 3 to 6 months. The plasma concentration of CyA was monitored.

RESULTSEighty-three children with nephrotic syndrome of different pathological types were treated with CyA, including 42 cases of minimal change nephrotic syndrome (MCNS), 31 cases of mesangioproliferative glomerulonephritis (MsPGN), 5 cases of membranoproliferative glomerulonephritis (MPGN) and 4 cases of focal segmental glomerular sclerosis (FSGS). All the 83 patients tolerated well to the CyA treatment. Forty-five cases got complete remission, 23 partial remission, 15 cases no change after one month treatment with CyA in the hospital. The overall response rate was 82%. Patients with different renal pathological types showed different responses. Among them, MCNS and MsPGN exhibited the best response rates of 86% and 84%, respectively; MPGN cases showed a lower response rate and FSGS cases showed the lowest rate. The response time was 7 to 45 days. The blood concentration of CyA was monitored for 1 week and 2 weeks after the drug was given. The effective drug concentration was maintained at 100 to 200 microg/L, and the course lasted for 3 to 6 months. During the follow-up of 83 cases, in 17 of 68 cases the disease relapsed when therapy was tapered or discontinued. The relapse rate was 25%. The results indicated that CyA would be effective to the relapsed cases. The serum creatinine increased temporarily after administration of CyA in 5 cases, N-acetyl-beta-D-glucosaminidase (NAG) in 8 cases and eventually reached the normal range after the adjustment of dosage. The side effects included anorexia, nausea, vomiting and so on.

CONCLUSIONCyA is one of the effective substitutes for the treatment of nephrotic syndrome, especially for the cases with MCNS and MsPGN. And CyA could control refractory nephrotic syndrome effectively and rapidly. The clinical effect was related to the blood concentration of CyA and pathological types.

OBJECTIVEStudying the gene expression profiling of different stage hairy root of Salvia miltiorrhiza, in order to find functional genes.

METHODThe contents of second metabolites were determined by HPLC and gene expression profiling was detected by cDNA microarray. cDNA labeled with a fluorescent dye (Cy5 and Cy3-dCTP) was produced by Eberwine's linear RNA amplification method and subsequent enzymatic reaction. The microarrays were scanned with a ScanArray Express scanner using ScanArray 2.0 software and quantified by signal intensities of individual spots from the 16-bit TIFF images using GenePix Pro 4.0. The linear normalization method was used for data analyze. Northern blot was used to test the gene expression results obtained by microarray. Different expressed genes were sequenced and analyzed by gap4 software, and then they were analyzed with BLASTX, BLASTN, GO and KEGG.

RESULTGrowth rate and second metabolites analysis indicated that the stage from 30 d to 45 d was the growth stage, while the stage from 45 d to 60 d was the second metabolites accumulation stage. Accordingly 30 d hairy root was chosen as a reference, which was hybridized with 45 d and 60 d hairy root separately. Total 203 different expressed genes were obtained. Northern blot showed that the result was identical with the microarray result. After sequenced, there were 172 genes clustered into 114 clusters (Unigenes). Among them, 62 unigenes had known functions, 34 unigenes were hypothetical protein, 9 unigenes were homologues with no similarity and 9 unigenes were unidentified protein with low similarity. Total 67 genes were classified into cellular component ontology, molecular function ontology and biological process ontology based on GO analysis. Total 26 genes, which represented 29 metabolic-related enzymes, were located in metabolic maps based on KEGG pathway classification.

CONCLUSIONSeveral important functional genes related to second metabolite synthesis were cloned such as P450 and copalyl diphosphate synthase genes. cDNA microarray was a useful tool for functional genomics of traditional Chinese medicine.
