OBJECTIVE: To establish a method of molecular biology to identify the authenticity and varieties of Penis et Testis Cervi rapidly, simply and accurately. METHODS: The mitochondrial DNAs (mtDNA) of dried Cervus nippon Penis, Cervus elaphus. L Penis, Penis et Testis Bovis and commercial products were extracted and purified with column chromatography. A pair of primers were designed for PCR special amplification of mtDNA according to cytochrome b gene sequence in the cervidae mtDNA GenBank; the products of PCR were analyzed for the single strand conformation polymorphism (SSCP) by denaturing polyacrylamide gel electrophoresis (PAGE). RESULTS: The positive control samples and some commercial products showed clear single strand DNA (ssDNA) bands with different mobility, but the negative control sample and some other commercial products showed nothing. CONCLUSION: Column chromatography method is a good way for getting mtDNA with high purity and less destruction of structure for the follow-up special PCR amplification; SSCP technique not only shows ssDNA bands of mutually complementing clearly, but also reveals the difference of mobility among ssDNAs from all samples directly. For that reason, the technique of PCR-SSCP will be reliable and feasible to indentify the authenticity and varieties of products from cervidae.

Objective:To investigate the expression of Bcl-2 and Bax in renal tissues of patients with hepatitis B virus- associated glomerulonephritis(HBV-GN).Methods:Twenty HBV-GN specimens with complete nephrology data and 10 normal renal specimens were randomly chosen for the present study.Cell apoptosis was detected by means of terminal deoxynucleotidyl transferase mediated d-UTP nick end labeling(TUNEL)and the apoptotic index was calculated;immunohistochemistry was used to detect the protein expression of Bax and Bcl-2.ResuLts:The apoptotic index in HBV-GN group was obviously higher than that of the control group;the apoptotic cells were mainly distributed in the proximal and distal renal tubules and the collecting duct epithelial cells,seldom seen in the glomerular cells.The expression of Bcl-2 in HBV-GN patients was predominately present in the renal tubular epithelia cells(positive in the plasma,membrane and nuclear);the expression of Bax was found in both glomerular cells and renal tubular cells,mainly in tubular epithelial cells,seldom seen in Bowman's capsule or glomerular mesangial region.Conclusion:Apoptosis in the kidney of HBV-GN patients mainly occurs in the renal tubular epithelial cells;expression of Bax and Bcl-2 is mainly in the renal tubular epithelial cells,suggesting that the injury of tubular interstitial damage may be one of the important factors for the development of HBV-GN.

The research and quality control of traditional Chinese medicine has meaningful importance, because it has influence not only in the health and treatment of patients, but also in the solid growth and development of phar-maceuticals companies. In some cases, for the complex of TCM, the common QC method on single or multi-target compounds can't really and truly disclose the quality of the Chinese materia medica. Therefore, a lot of researchers do plenty of works to make clear the effectiveness basis, to improve the quality and realize the modernization of TCM. All of these works close together with modern analysis and separation technology. In this article, a novel analy-sis technology-UltraPerformance Convergence Chromatography (UPC2) based its characters and applications should be introduced. It should be a helpful technology for the TCM researchers to facilitate the study and QC works.

Objective To determine the role of activated status of peroxisome proliferator-activated receptorγ/nuclear factor-κB ( PPAR-γ/NF-κB ) in coagulation disorders induced by sepsis. Methods Forty male Sprague-Dawley ( SD ) rats were randomly divided into four groups, n = 10 in each group: control group, lipopolysaccharide ( LPS ) challenged group, rosiglitazone ( ROSI, selective agonist of PPAR-γ) pretreatment group, and GW9662 ( PPAR-γ antagonist ) pretreatment group. The sepsis model was reproduced by injection of 6 mg/kg LPS via sublingual vein, and the rats in control group were injected with 2 mL/kg normal saline. The rats in ROSI pretreatment group were given 0.3 mg/kg ROSI by sublingual venous injection followed by injection of LPS 30 minutes later;and in GW9662 pretreatment group rats were given 0.3 mg/kg GW9662 by sublingual venous injection followed by 0.3 mg/kg ROSI 15 minutes later, followed by injection of LPS 30 minutes later. Blood was collected at 4 hours after LPS administration, and the expressions of PPAR-γ and NF-κBp65 in peripheral blood mononuclear cell ( PBMC ) were determined with immunocytocheminal technique and graph analysis. Plasma prothrombin time ( PT ), activated partial thromboplastin time ( APTT ), fibrinogen ( FIB ), and D-dimer were determined simultaneously. Results① PPAR-γ/NF-κB pathway: the expressions of PPAR-γ and NF-κBp65 were lowered in control group, and they were expressed in cytoplasm. In LPS challenged group the expression of PPAR-γ ( gray value ) was slightly increased but with no significant difference as compared with control group ( 111.01±4.06 vs. 98.46±5.99, P >0.05 ). In ROSI pretreatment group the expression of PPAR-γ( gray value ) was significantly higher than that in LPS challenged group ( 214.38±5.79 vs. 111.01±4.06, P<0.01 ), with dislocation into nuclei. In GW9662 pretreatment group the expression of PPAR-γ ( gray value ) was lowered but without significant difference compared with that of control group ( 44.21±2.64 vs. 98.46±5.99, P>0.05 ). In LPS challenged group the expression of NF-κBp65 ( gray value ) was significantly higher than that in control group ( 249.48±6.86 vs. 105.81±10.19, P < 0.01 ), and it was translocated into the nuclei. In ROSI pretreatment group the expression of NF-κBp65 ( gray value ) was significantly lower than that in LPS challenged group ( 102.47±8.05 vs. 249.48±6.86, P < 0.01 ), and it lied in cytoplasm. In GW9662 pretreatment group the expression of NF-κBp65 ( gray value ) showed no significant difference as compared with that of LPS challenged group ( 214.84±7.91 vs. 249.48±6.86, P>0.05 ).②Coagulation:compared with control group, PT and APTT were significantly prolonged, FIB was significantly decreased, and D-dimer was significantly increased in LPS challenged group [ PT ( s ):18.32±2.03 vs. 12.22±1.38, APTT ( s ):40.05±2.72 vs. 26.64±2.73, FIB ( g/L ): 1.65±0.51 vs. 3.60±0.37, D-dimer ( mg/L ): 2.58±0.73 vs. 0.37±0.06, all P < 0.01 ]. Compared with LPS challenged group, APTT and PT were significantly shortened, FIB was significantly increased, and D-dimer was significantly lowered in ROSI pretreatment group [ PT ( s ):13.93±1.67 vs. 18.32±2.03, APTT ( s ):30.29±0.86 vs. 40.05±2.72, FIB ( g/L ):3.18±0.69 vs 1.65±0.51, D-dimer ( mg/L ):0.40±0.12 vs. 2.58±0.73, all P<0.01 ]. All parameters in GW9662 pretreatment group showed no significant difference as compared with those of LPS challenged group. Conclusions PPAR-γagonist ROSI may ameliorate coagulation disorders in septic rats. PPAR-γ/NF-κB transduction pathway plays an important role in septic coagulopathy.
