Objective To evaluate the clinical value of the quantitative detection of plasma 1,3-β-D-glucan in penicilliposis marneffei. Methods The 1,3-β-D-glucan concentrations were detected by using a G test. Results In 60 New Zealand rabbits infected by Penicillium marneffei,the levels of 1,3-β-D-glucan were positively correlated with infectious severity. The sensitivity, specificity, positive predictive rate and negative predictive rate were 88.3%、100%、 100% and 58.8% respectively,which were significantly higher than those of the control group(P <0.01 ).Conclusion The quantitative method for the detection of 1,3-β-D-glucan in plasma was simple,sensitive and reliable, and could be used as the assisting diagnosis of penicilliposis marneffei at early stage.

Transforming growth factor-β is an important cytokine with various bioactivities, including embryonic development, wound healing, chemotaxis and cell cycle regulation. Epithelial-mesenchymal transition (EMT) is the main pathway of tumor cell to obtain the ability of invasion and metastasis. The TGF-β is the key factor known to induce EMT in cancer cells and plays an important role in the process. In recent years, some progress has been obtained. Some TGF-β inhibitors have approved in the market or in clinical trials. TGF-β inhibitors can play an important role on the treatment of tumors, glaucoma, liver and kidney fibrosis disease and scar repair. Novel TGF-β inhibitors reported in recent years were reviewed in this article.

Recent studies suggested that the prostate cancer may arise from prostate cancer stem cells that share some same characteristics with normal stem cells. The purpose of this study was to detect the differences of Nanog expression between PC3 prostate cancer cell line and its tumor stem cells, and the relationship was preliminarily examined between Nanog and prostate cancer and its tumor stem cells. By using magnetic active cell sorting (MACS), we isolated a population of CD44(+)/CD133(+) prostate cancer cells that display stem cell characteristics from PC3 cell line. Immunohistochemistry revealed positive expressions of CD44, CD133 and α(2)β(1)-integin in the isolated cells. CCK-8 analysis showed that isolated cells had a strong proliferative ability. The formation of the cell spheres in serum-free medium and holoclones in serum-supplied medium showed that the cells were capable of self-renewing, indicating that the isolated cells were a population of cancer stem-like cells derived from PC3 cell line. Western blotting exhibited that the isolated cells had higher experession of Nanog, an embryonic stem marker, as compared with PC3 cells. Our study showed that Nanog might be helpful in sustaining the self-renewal and the undifferentiation of prostate cancer stem cells, and may serve as a marker for prostate cancer stem cells for isolation and identification.

Background: Integrative traditional Chinese and western medicine may be a new approach to improve the eradication rate of Helicobacter pylori (Hp).Aims: To compare the efficacy and safety of Weifuchun tablet versus bismuth combined with standard triple regimen as the first-line therapy of Hp infection.Methods: A total of 141 patients with Hp infection and na(i)ve to treatment were randomly assigned into 3 groups receiving a 14-day eradication therapy.In standard triple therapy group, esomeprazole, amoxicillin and clarithromycin were given twice a day;while in Weifuchun group and bismuth group, Weifuchun tablet and bismuth potassium citrate were added, respectively, to the standard triple therapy.Hp eradication was assessed by 13C-urea breath test at least 6 weeks after the end of treatment.Hp isolates were tested for resistance to antibiotics.Results: One hundred and twenty-eight patients completed the study.Hp eradication rates in Weifuchun group, bismuth group and standard triple therapy group were 83.7%, 91.8% and 79.1%, respectively by ITT analysis and 88.4%, 97.8% and 84.6%, respectively by PP analysis.The eradication rate of Weifuchun group was lower than that of bismuth group and higher than that of standard triple therapy group, but the differences were not statistically significant (P>0.05).Only PP eradication rate of bismuth group was significantly higher than that of standard triple therapy group (P<0.05).The resistant rates of Hp to clarithromycin, amoxicillin and metronidazole were 33.3%, 2.9% and 70.5%, respectively.For eradication of clarithromycin resistant strains, bismuth group was superior to Weifuchun group and standard triple therapy group (100% vs.60.0% and 66.7%, P all <0.05).All three eradication regimens showed good compliance, and no significant difference in incidence of adverse events was found between the three regimens (P>0.05).Conclusions: Weifuchun tablet combined with standard triple regimen is safe and effective for use as first-line treatment for Hp infection, however, the eradication rate is relatively low in cases infected with clarithromycin resistant strains.Bismuth combined with standard triple regimen is a good alternative in areas with high clarithromycin resistance and regions where tetracycline is unavailable.

Over the past two decades, multiple drug-resistant infections have escalated globally with the significantly increased morbidity and mortality due to the unreasonable uses of antimicrobial agents in areas such as animal husbandry, industry and medicine. As the situation of drug resistance has been progressively serious, anti-drug-resistant clinical strategies have attracted widely social concerns. This review will report the current status of antibiotic resistance and the mechanism of antibiotic-resistance all over the world. The anti-drug resistance strategies are the emphasis of our report, including the new indication of old antibiotics, the combination of existing antibiotics, the development of new antibiotics, nano-antibiotics, and non-infection treatment with immunomodulators and phage. This review aims to further understand the current situation of drug resistance, which optimizes the strategies of drug-resistant bacteria and clinical services.

Objective To evaluate the effect of fingolimod(FTY720) on angiotensin Ⅱ(AngⅡ)-induced renal oxidative stress in rats and its possible mechanisms.Methods Thirty-six male Sprague-Dawley rats were divided into three groups through random number tables:AngⅡ infusion group(twelve rats,infusion of AngⅡvia subcutaneous osmotic pumps),0.9% sodium hydrochloride solution infusion group(twelve rats,infusion of equal volume of 0.9% sodium hydrochloride solution via subcutaneous osmotic pumps) and FTY720 intervention group(twelve rats,intra-gastric administration of FTY720 besides AngⅡ infusion).Urine samples were collected for 24 hours every week.Blood samples and kidneys were collected when rats were sacrificed at day 14 and 28 d respectively.MDA and T-SOD assay Kits were used to detect the concentrations of MDA and T-SOD in serum and kidney homogenates.Renal pathological changes were observed by light microscope.The expression of Nox4 in the kidneys was evaluated by immunohistochemistry.Results Compared with 0.9% sodium hydrochloride solution infusion rats of the same period,AngⅡ-infused rats developed significant proteinuria.The concentration of serum creatinine,urea nitrogen,AngⅡ and MDA were increased(P<0.05),T-SOD was significantly decreased on days 14 and 28(P<0.05),the serum albumin was significantly increased on day 28(P<0.05),while FTY720 partially reversed these changes.The renal tissue of AngⅡ-infused rats presented mesangial cells proliferation,mesangial matrix deposition,tubular epithelial cells effacement,sclerosis and atrophy in part of the glomerular.FTY720 can alleviate these changes.Immunohistochemistry showed that Nox4 was primarily located in the distal tubule.The expression of Nox4 was significantly increased in AngⅡ-infused rats as compared with that of 0.9% sodium hydrochloride solution infused group rats,and FTY720 administration prevented the change effectively.Conclusion AngⅡ-induced renal injury could be attenuated by FTY720 via preventing oxidative stress.
