Objective The changes of cytokine expression on a genomic scale in CD4 + cell of mice c hronically infected with Schistosoma japonicum and their roles in the pathog enesis of schistosomiasis were studied. Methods CD4 + cells were isolated from sp le ens of mice 13 wk infected with Schistosoma japonicum. We used the cDNA micr oarr ay technique to explore the cytokine gene expression profile of CD4 + cells f ro m normal and chronic infected mice. Three-color flow cytometry was performed to study intracellular protein levels of IFN-?、IL-4 of CD4 + cell. Results In the CD4 + cell of chronically infected mice, IL-4 was remarkably increase d at both transcription and protein expression levels (P
3.A decade's evidence review of sildenafil citrate.
National Journal of Andrology 2009;15(1):3-6
Erectile dysfunction (ED) is one of the most popular and disturbing sexual problems, which impairs patients' health and affects their quality of life. Sildenafil citrate, the first oral PDE-5 inhibitor in the world, has established its efficacy and safety credit in both doctors and ED patients. The authors reviewed the results of related studies in the last decade and made deeper insights into the use of sildenafil citrate in such aspects as the general drug tolerance and its influence on the cardiovascular system, potentiality of concomitant diseases with co-administration of other drugs, long-term safety, and ocular and genital safety.

4.Chinese men's attitudes to life events and sexuality: prevalence of erectile dysfunction and related health concerns among Chinese men in Asian MALES study.
National Journal of Andrology 2006;12(11):1048-1052
OBJECTIVEThe aims of Asian Men's Attitudes to Life Events and Sexuality (Asian MALES)-China study were to identify the prevalence of erectile dysfunction (ED) and related health concerns in the general male population in China, and to examine the attitudes and behaviors of men in relation to these health issues.
METHODSA total of 2055 men aged 20-75 years were included in Phase-I MALES study using a standardized questionnaire, and another 225 recruited from the sub-sample of Phase-I MALES participants with reported ED and some ED patients from other sources were involved in Phase-II Asian MALES- China study, with the prevalence of ED and men's associated attitudes as the main measure.
RESULTSThe overall rate of ED in the Asian MALES-China sample was 5.9%. The rate of self-reported ED rose with age increase. A higher rate of ED was reported in men with co-morbid medical conditions and risk factors, including cardiovascular disease, hypertension, dyslipidemia, and depression, and so were the rates of these co-morbid conditions in ED patients. Data from Phase-II Asian MALES-China indicated that among men with reported ED, only 17% would seek treatment.
CONCLUSIONThe rate of ED is high in Chinese men and it is associated with co-morbid conditions. For Chinese men, it is necessary to know more about ED and to seek safe and effective treatment of its symptoms.

Objective To evaluate the locating effects of a portable ultrasound for leg perforator flaps,and the clinical effects of leg perforator flaps for the wounds of the extremities.Methods Since December 2009 to March 2011,thirty-one cases of soft tissue defects of the extremities were treated with free vascularized leg perforator flaps in our center.A portable ultrasound were used for the locating of the perforator arteries of the leg before the operations.These flaps include 24 cases of the fibular artery perforator flaps (4 with simultaneous fibula transfer),three cases of the posterior tibia artery perforator flap,two cases of the medial gastrocnemius artery perforator flap,and 2 cases of the lateral gastrocnemius artery perforator flap.The flap size ranged from 15.0 cm × 8.0 cm to 1.0 cm × 1.5 cm.The caliber diameter of the perforator artery ranged from 0.2 mm to 1.8 mm.The wounds included 21 cases of the hand,five cases of the forearm,and 5 cases of the leg.Results The coincidence rate intraoperatively of the portable ultrasound was 96.8%.All the flaps survived and the wounds healed uneventfully.The donor site of the flaps were either closed directly or closed with partial split-thickness skin graft.Conclusion The portable ultrasound is an effective,reliable and accurate instrument for locating the leg perforator flaps.The leg perforator flaps have the advantages of convenient harvest,satisfactory thickness,less donor site morbidity,and high survival rate.

Platinum-based anticancer drugs have been becoming one of the most effective drugs for clinical treatment of malignant tumors for its unique mechanism of action and broad range of anticancer spectrum. But, there are still several problems such as side effects, drug resistance/cross resistance and no-specific targeting, becoming obstacles to restrict its expanding of clinical application. In recent years, supramolecular chemistry drug delivery systems have been gradually concerned for their favorable safety and low toxicity. Supramolecular macrocycles-platinum complexes increased the water solubility, stability and safety of traditional platinum drugs, and have become hot focus of developing novel platinum-based anticancer drugs because of its potential targeting of tumor tissues/organs. This article concentrates in the research progress of the new drug delivery system between platinum-based anticancer drugs with three generations of macrocycles: crown ether, cyclodextrin, cucurbituril and calixarene.

8.Advances in the treatment of erectile dysfunction by viagra.
National Journal of Andrology 2005;11(4):314-319
Viagra has become the first line drug for the treatment of erectile dysfunction since it was first introduced in 1998. Its efficacy and safety have been sidely acclaimed as being definite. This article presents a brief review about the advances in the studies of Viagra, including its therapeutic effect and safety, its protection of penile health, and its promotion of self-esteem and sexual relationship.

Aim The effect of tetrandrine on TGF-?1 mRNA expression in glomerulosclerosis rat was observed. Methods The rats were randomly divided into four groups, such as the normal control group (sham operative rat), glomerulosclerosis model group,tetrandrine group and amlodipine group. The expression of TGF-?1 mRNA was analyzed by Northern blot hybridization. Results The expressions of TGF-?1 mRNA in two treating groups were much lower than untreated model group. There were no difference between these two treating groups. Conclusion Tetrandrine can decrease the expression of TGF-?1 mRNA in glomerulosclerosis rat induced by unilateral renctomy plus adriamycin.

Objective To discuss the molecular mechanism of 18F-fluorodeoxyglucose (FDG) uptake in tumor and to assess its value to identify pathologic type and cancer staging in patients with earlystage nasopharyngeal carcinoma.Methods Forty patients with nasopharyngeal carcinoma of early-stage,including 12 cases with T1 stage and 28 cases with T2 stage, underwent FDG PET imaging.The maximum standardized uptake value ( SUVmax ) and mean standardized uptake value ( SUVmean ) of FDG uptake of each patient were measured and compared between T1 and T2 stage by t-test.The expression of glucose transport protein 1 ( Glut1 ) and hexokinase- Ⅱ ( HK- Ⅱ ) of each case was measured in paraffin sections by streptavidin-perosidase (SP) immunohistochemistry.The positive expression rate of Glut1 and HK- Ⅱ was calculated and compared between T1 and T2 by x2 test.Meanwhile, the correlation between the expression of Glut1 or HK-Ⅱ and the SUVmax was tested by Pearson analysis.Results The SUVmax and SUVmean in 40 patients were 9.45 ± 1.87 and 6.04 ± 1.09, respectively.The SUVmax of patients with T1 stage (8.95 ± 1.91 ) was significantly lower (t =4.46, P<0.001 ) than that of patients with T2 stage (11.55 ± 1.70), and the SUVmean of patients with T1 stage (5.61 ± 1.08) was significantly lower ( t = 6.76, P < 0.001 ) than that of patients with T2 stage (7.98 ± 1.10) too.Among 40 patients, all patients showed positive expression of Glut1 and HK-Ⅱ , and the positive expression rate of Glut1 and HK-Ⅱ was ( 45.2 ± 10.9 )% and ( 68.3 ±9.5)%, respectively.The positive expression rate of Glut1 was (38.4 ±8.1)% in T1 stage and (49.7 ±12.6)% in T2 stage, which displayed no difference (x2 =40.58, P>0.05), but the HK-Ⅱ positive expression rate showed significant difference (x2 =58.71, P<0.05) between T1 stage (60.1 ±11.1)% and T2 stage (77.9 ± 14.7 )%.The correlation analysis indicated that there was low-degree positive correlation (r =0.369, P=0.019) between the SUVmax and Glut1 expression, and there was medium-degree positive correlation (r = 0.549, P = 0.001 ) between the SUVmax and HK-Ⅱ expression.Conclusion Expression of Glut1 and HK-Ⅱ was positively correlated with FDG uptake in patients with early-stage nasopharyngeal carcinoma.
