Aim The effect and mechanism of human placental extract(HPE) on the lipoprotein-cholesterol metabolism, peroxidation and the function of platelet aggregation in hyperlipaemia rats were abserved.Methods Wistar rat with hyperlipaemia models were given each HPE 0.4 ml (100 g)-1?d-1 through lavage for 12 days.The serum levels of TG,TC,LDL-C,HDL-C and HDL2-C in its subgroup were measured.The activies of LPO and SOD in both blood and liver tissue were determined .The effect of HPE on lipidosis of liver were abserved by fat dyeing.The levels of 6-keto-PGF1?,TXB2 in plasma and maximum platelet aggregation rate were measured by ELASA. Result The levels of HDL-C and HDL2-C were increased (P

OBJECTIVETo assess the significance of platelet activation in unstable angina pectoris (UA) and acute myocardial infarction (AMI), and to explore the relationship of clinical effect of Xuefu Zhuyu concentrated pill (XCP) in vivo and the serum pharmacological anti-platelet activating effect of XCP in vitro.

METHODSBy flow cytometry and special labelled antibodys to detect the whole blood platelet membranous glycoprotein CD62P and CD41/45 expressions in UA patients before and after XCP treatment, as well as those in peripheral blood of AMI rats before and after co-cultured with XCP containing serum from patients at 37 degrees C for 30 min.

RESULTSCD62P and CD41/45 expressions increased significantly in UA patients to 24.36 +/- 7.91% and 29.51 +/- 12.21% respectively. After effective treatment, they decreased to 19.57 +/- 7.22% and 20.87 +/- 8.73% respectively accompanied with increase of platelet adhesion and aggregation rate. The difference of CD62P before and after treatment was significant (P < 0.05). CD62P in blood of AMI rats was 39.73 +/- 12.36%, after being co-cultured with XCP containing serum from patients treated effectively, it reduced to 30.41 +/- 10.36% (P < 0.05), but after co-cultured with the serum from patients treated ineffectively, it showed less intervention effect (P > 0.05).

CONCLUSIONPlatelet was highly activated in UA patients and AMI rats. The consistency between clinical holistic effect of XCP and serum pharmacological effect of XCP in platelet activation inhibition reflects a good correlation between serum pharmacological effect of Chinese herbal medicine and its clinical holistic effect.

Objective To explore the impacts of over-expression of microRNA-7 (miRNA-7) on the sensitivity of cis-platin in esophageal carcinoma cell line TE-1, and the possible mechanism thereof. Methods Lipofectmin 2000 method was used to transient transfect with miRNA-7 mimic into esophageal cancer cell line TE-1, which was taken as transfection group, mimic negative control was taken as transfection conrtol group. The expressions of miRNA-7 and epidermal growth factor receptor (EGFR) mRNA were detected by RT-PCR in the above two groups and normal control group. The total EGFR and EGFR in cytoplasmic and nucleus were detected with Western blot assay in transfection group and transfection control group. CCK-8 was used to detect IC50 of cisplatin in transfection group and transfection control group. The expression of EGFR was observed with immunofluorescence confocal microscope in two groups. Results The miRNA-7 expression was signifi-cantly increased in transfection group than that of transfection conrtol group and control group. The expression of EGFR mRNA was significantly reduced in transfection group (P<0.001). The total EGFR was significantly decreased in transfec-tion group than that of transfection conrtol group. The level of nuclear EGFR was significantly increased ( P<0.01),and cyto-plasm EGFR expression was significantly decreased in transfection group than that of transfection control group ( P<0.05). CCK-8 results showed that after the over expression of miRNA-7 in TE-1, the IC50 of cisplatin (48 h) increased in transfec-tion group than that of control group (P<0.01). Immunofluorescence results showed that EGFG in nuclear was higher in transfection group than that of transfection control group but its expressions reduced in cell membrane and cytoplasm. Con-clusion The over-expressed miRNA-7 in esophageal cancer cells TE-1 can reduce cisplatin sensitivity by the increased EGFR in nuclear translocation.

One of the challenges in andrology nowadays is the diagnosis and treatment of external genital abnormalities and defects along with the consequent voiding, sexual, and reproductive dysfunctions, for which no guidelines are yet available. Hitherto, surgical repair and reconstruction are efficient for these diseases. The key to these operations is to individualize surgical strategies according to the specific local lesion and dysfunction, usually involving flap and graft techniques. This article presents our experience in the surgical treatment of penile and scrotal abnormalities and defects with urological and andrological techniques and microsurgical strategies, focusing on the external repair and functional reconstruction. Satisfactory treatment outcomes pivot on a precise evaluation of the disease, a rational design of surgical procedures, and an earnest communication with the patient. Some cases are rather complicated and challenging, usually with complications, and therefore deserve further researches for more effective treatment strategies in clinical practice.

Objective To compare the relative efficacy and quality of extraction of human fecal DNA using four methods.Methods Real-time PCR were utilized for analysis both quantification and quality of the fecal targeted bacteria(including gut all eubaeterium,Bacteriodes-PrevoteUa group,Bifidobacterium spp Enterobacteriaceae and Enterococcus spp)by using 16s rRNA gene-targeted genus or group-specific primer sets.Results The negative rat of PCR product from method 3(phenol-chloroform plus bead-beating) was about 40%(4/10)by using universal primers,the PCR inhibition disappeared after fecal DNA purified with column.The total fecal 16s rRNA gene copy numbers(per gram of wet weight of feces)as well as the numbers of Bacteriodes-Prevotella group from method 1(QIAamp~DNA stool mini kit)and 4(QIAamp~ DNA stool mini kit combined with bead-beating)was higher significantly than that from method 2(FastDNA ~Kit,Biol01)and 3(P

Objective To evaluate the protecting effects of matrine on chemotherapy related hepatic lesion and its possible mechanism.Methods The positive rate and severity of hepatic lesion were compared between pa- tients being treated with or without matrine during chemotherapy processes.Furthermore,the difference of liver pro- tecting effect of this Chinese medicine between hepatitis B virus(HBV)infection chemotherapy patients and disinfec- tion patients were also analyzed.Results Both the rate of hepatic lesion and level of ALT in matrine treated group were much lower than those in untreated group in chemotherapy patients.The rate of hepatic lesion and level of ALT in HBV infection patients were higher than those in HBV disinfection patients in untreated group,while the signifi- cant difference of these two parameters between HBV infection patients and disinfection patients were disappeared in matrine treated group.Conclusion Matrine has hepatic protecting effect in chemotherapy related liver lesion.
