Objective To evaluate the efficacy and safety of sorafenib in the treatment of advanced renal cell carcinoma.Methods The clinical date of 33 patients with advanced renal cell carcinoma from September 2007 to April 2012 was reviewed retrospectively.26 were males and 7 were females,with an average age of 69 years.Pathological diagnosis showed 30 clear cell RCCs,2 papillary RCCs,and 1 unclassified RCC.These patients were treated by sorafenib 400 mg twice a day until intolerable toxicity or disease progression.The primary end points were objective response rate,clinical benefit rate,median survival time,median progression-free survival and the incidence of adverse reaction.Results All patients were evaluable for response and toxicity,with 8 patients (24%) of partial remission,19 cases (58%) of stable disease,and 6 cases (18%) of disease progression.The disease control rate was 82%,the median progression-free survival was 10.2 months,while the median survival time was 16.5 months.The common adverse reactions included hand-foot skin reaction (61%),diarrhea (46%),hypertension (21%).Most adverse reactions occurred around the second week after drug therapy,with the duration unequal.The majority of adverse reactions could be released by symptomatic treatment,which did not affect the medication.Conclusion Sorafenib has good short term efficacy for patients with advanced renal cell carcinoma,and most adverse reactions were tolerable.

Objective: To study the antipyretic action of Dipseudoephedrine Glycyrrhizin and its effect on heart rate and blood pressure of rats.Methods: The model of pyretic rabbit was established by diphtheria-pertussis-tetanus triple vaccine,and to observe the effect of Dipseudoephedrine Glycyrrhizin on temperature of rabbit. Two-path physiological recorder was used to measure heart rate and blood pressure.Results: The experiment proved that Dipseudoephedrine Glycyrrhizin can decrease the anus temperature of pyretic rabbit obviously.Dipseudoephedrine Glycyrrhizanate had no remarkably effect on heart rate and blood pressure.Conclusion: Dipseudoephedrine Glycyrrhizin has antipyretic action and has no effect on heart rate and blood pressure within studied dose.

OBJECTIVETo investigate the status of human papillomavirus ( HPV) infection and its genotypes in male patients in Zhenjiang area.
METHODSUsing PCR and reverse dot blot hybridization, we determined the genotypes of HPV DNA in 245 male patients at our Clinic of Dermatology and STD.
RESULTSThe total rate of HPV infection was 43.67% (107/245), and 18 subtypes were detected. Among the 107 HPV-positive cases, low-risk, high-risk, and combined high- and low-risk infections accounted for 39.25% (42/107), 38.32% (41/107), and 22.43% (24/107), respectively. The most notable low-risk HPV types were HPV6 and HPV11, and the most notable high-risk HPV types were HPV16, HPV52, and HPV58. The rates of single infection and multi-infection were 53.27% (57/107) and 46.73% (50/107), respectively. One case had the most types, infected with 8 genotypes. No statistically significant differences were observed in the total rate of HPV infection among different age groups (Χ2 = 7.999, P > 0.05).
CONCLUSIONThe dominant subtypes of HPV infection in male patients in Zhenjiang area were HPV6, HPV11, and HPV16. The most common subtypes were HPV6 and HPV11 in low-risk infection, and HPV16, HPV52, and HPV58 in high-risk infection.

Objective To investigate the correlation between asymmetric dimethylarginine (AD-MA) and endothelial dysfunction in patients with uremia.Methods Uremic patients who did not receive hemodialysis were defined as A group (n =40) ; uremic patients who had received hemodialysis were divided into B group (n =45) ;healthy people were defined as C group (n =20) ;and chronic kidney disease (stage 2 ~ 4) patients were defined as D group (n =20).The diameter of intima-media thickness,and endothelium-dependent or independent dilation (EDD or EID) of radial artery in right forearm were detected with diasonography.The levels of ADMA were determined by high-performance liquid chromatography.Results Compared to C group,the levels of ADMA in A,B and D groups were significantly increased [C:(0.78 ±0.19) μmol/L,A:(1.51 ±0.16) μ mol/L,B:(1.13 ±0.14) μmol/L,D:(0.92 ±0.11) μmol/L; P <0.05].Compared to A group,the levels of ADMA were significantly decreased in B group (P <0.05).EDD and EID were decreased significantly in A,B and D groups compared to C group [EDD:C:(13.52±1.73)% vs A:(7.32 ±0.54)%,B:(9.02 ±0.86)%,D:(10.13 ±1.25)%,P <0.05;EID:C:(14.45±1.85)% vsA:(10.37 ±1.51)%,B:(9.54±1.39)%,D:(11.17±1.56)%,P <0.05].EDD in B group was significantly lower than A group (P <0.05).In group A,a negative correlation was found between EDD and the level of ADMA (r =-0.81,P =0.020).Conclusions ADMA level was significantly increased in uremic patients.A close correlation existed between ADMA and endothelial dysfunction of radial artery.

Previous study on TNFRl-mediated hepatocyte apoptosis has been implicated in the development of fulminant viral hepatitis.To interfere with the potentially effective target,plasmid named p-mTNFR1shRNA complimentary to the sequence responsible for mTNFR1 was also constructed and further confirmed by sequence analysis.To investigate the effect of mTNFR1shRNA plasmid on mTNFR1 expression in vivo and the disease progress in MHV-3 induced fulminant hepatitis mice model.By hydrodynamic injection of mTNFRlshRNA plasmid,the survival rate of mice,hepatic pathological change were examined and compared between mice with/without mTNFR1 shRNA plasmid intervention.The expression of mTNFR1 was detected by Real-time PCR,immunohistochemistry staining.The mTNFR1 shRNA plasmid significantly reduced mTNFR1 expression in vivo,markedly ameliorates inflammatory infiltration,prolonged the survival time period and elevated the survival rate from 0 up to 13.3% in Balb/cJ mice with MHV-3 induced fulminant hepatitis.This study was designed to explore the opportunity of RNA interference technique in inhibiting TNFR1 expression,which has been reported to be involved in the development of a variety of diseases including fulminant viral hepatitis and severe chronic hepatitis B.

OBJECTIVETo investigate the changes of the cardiac hemodynamics after acute high altitude exposure in healthy young males and the relationship with acute mountain sickness(AMS).
METHODSLeft ventricular function and oxyhemoglobin saturation (SaO2), heart rate (HR), blood pressure (BP) were measured in 218 healthy young males before and after high altitude exposure within 24 h respectively. According to the lake louise score criteria, the subjects were divided into two groups: acute mountain sickness group (AMS group) and non acute mountain sickness group (non-AMS group).
RESULTSHR, diastolic blood pressure (DBP), mean arterial pressure (MAP), left ventricular ejection fraction (LVEF), stroke volume (SV), stroke index (SI) cardiac output (CO), cardiac index (CI) were significantly increased upon acute high altitude exposure (P < 0.05). Whereas SaO2 and end-systolic volume (ESV) were significantly decreased (P < 0.05). In addition, HR, systolic blood pressure (SBP) and MAP in AMS group were significantly higher than those in non-AMS group (P < 0.05). But stroke index (SI) and end-diastolic volume (EDV) in AMS group were significantly lower than those in non-AMS group (P < 0.05).
CONCLUSIONCardiac function in healthy young males upon acute high altitude exposure was enhanced. EDV, HR and SI might become the indexes of predicting the acute mountain sickness in the future.

Aim To look for novel small-molecule inhibitors of CDK9 through structure-based virtual screening and biological activity determination.Methods Homology modeling of CDK9 was based on the 3-D structure of other cyclin-dependent kinase family members,and then virtual screening by DOCK(molecular docking)of database of small molecule was carried on.MTT method was used in inhibition of tumor cell growth in vitro,while Western blot was used for further study of molecular mechanisms.Results From the top 1000 compounds with the best DOCK energy score,27 compounds were selected for biological assay based on the diversity of chemical structure and functional group.12 of 27 selected compounds showed significantly inhibition activity on tumor cell proliferation,and only one compound in 12 with half-maximum inhibition concentration(IC50)values less than 20 ?mol?L-1 named C-21 was selected for further molecular mechanism study.The western blotting data showed C-21 compound could effectively inhibit CDK9 from phosphorylating large subunit C-terminal of RNA polymerase Ⅱ in a dose-dependent manner.Conclusions Through homology modeling,virtual screening by computer,determination of biological activity and experimental studies of molecular mechanism,a new promising lead compound targeted for CDK9 was found and confirmed.
