Objective To determine the in vitro antifungal effects of closantel against Candida albicans.Methods A microdilution method was used to determine the minimum inhibitory concentration (MIC)of fluconazole alone and in combination with closantel against Candida albicans standard strain CAF-2.Ten strains of Candida albicans were cultured in RPMI-1640 liquid culture containing 10％ calf serum with or without the presence of closantel at 16 mg/L,followed by the observation of hypha formation.Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) were performed to observe the ultrastructure of Candida albicans CAF-2 strain after exposure to closantel at 16 mg/L for 24 hours.Results Closantel could inhibit the growth of Candida albicans,and enhance the antifungal effect of fluconazole against Candida albicans in vitro.The percentage of Candida albicans forming hypha was 91.2％ ± 3.9％ in untreated Candida albicans,significantly higher than that in closantel-treated Candida albicans (29.8％ ± 5.1％,t =30.24,P ＜ 0.05).As TEM showed,closantel-treated Candida albicans gave a round,oval or pleomorphic appearance,with an irregular budding from the cell surface.Further more,the electron dense layer in the outer layer of cell wall was absent or unevenly distributed,the transparent layer was irregularly thickened,some cell membrane was locally disrupted or collapsed,and intracellular vacuoles increased after closantel treatment.Scanning microscopy revealed a rough surface,sparse and irregular budding of Candida albicans after treatment with closantel.Conclusion Closantel exhibits a promising anti-Candida albicans property in vitro.

Objective:To investigate the association of XPD rs13181 (codon751A/C, Lys751Gln), rs238406 (codon156C/A, Arg156Arg), XPC rs2279017 (i11C/A), and XRCC4 rs3734091 (codon247T/C, Ala247Ser) polymorphisms with colorectal cancer (CRC) susceptibility. Methods:A total of 338 patients with CRC who were treated at the Beijing Cancer Hospital from April 2013 to January 2016 (case group) and 315 healthy controls (control group) were genotyped using TaqMan technology. Results:The genotype GT and G alleles of XPD rs13181 increased the risk of CRC (GT>TT, adjusted OR=1.69, 95%CI=1.15-2.47, P=0.007;G>T, adjusted OR=1.77, 95%CI=1.19-2.64, P=0.005). The genotype GT and T alleles of XRCC4 rs3734091 increased the susceptibility of CRC (GT>GG, adjusted OR=9.02, 95%CI=5.61-14.50, P<0.001;T>G, adjusted OR=4.06, 95%CI=2.49-6.61, P<0.001). Analyses of XPD rs13181 and rs238406 indicated that the haplotype GT significantly decreased the risk of CRC (adjusted OR=0.39, 95%CI=0.18-0.85, P=0.018). Moreover, the combinations of the XPC rs2279017 G allele and the XRCC4 rs3734091 T allele (adjusted OR=28.43, 95%CI=6.85-117.95, P<0.001) and the XPD rs13181 G allele and the XRCC4 rs3734091 T allele (adjusted OR=10.24, 95%CI=4.69-22.35, P<0.001) exhibited significantly increased CRC risk. Conclusion:The polymorphisms of XPD rs13181 and XRCC4 rs3734091 increased the risk of CRC.

Objective To study the effects of angiogenesis inhibitor SU5416 on the growth and metastasis of pancreatic cancer in SD rat model. Methods Dimethylbenzanthracine (9 mg) (DMBA),was implanted into the parenchyma of Sprague Dawley rat pancreas to induce pancreatic cancer. Rats with established pancreatic carcinoma were randomly divided into 4 groups (15 rats each) to receive every the other day for consecutive 13 weeks before sacrifice peritoneal cavity injection of: Normal saline (control),5-fluorouracil 30 mg?kg -1 (5-Fu group),SU5416 16 mg?kg -1 (SU5416 group),and both 5-Fu and SU5416(combined treatment group). Tumor weight,inhibition rates,intratumoral microvessel density (MVD),apoptotic index (AI) and metastasis were evaluated. Results Tumor weight was (1.15?0.21) g,(0.68?0.42) g,(0.31?0.11) g,(0.19?0.06) g respectively;the inhibition rate was 0,48%,80%,85% respectively;the intratumoral microvessel density (MVD) was (12.3?3.2),(11.4?3.8),(2.1?1.5),(1.8?1.1) respectively;The apoptotic index (AI) was (2.64?1.86)%,(5.71?3.14)%,(13.21?4.26)%,(21.12?7.15)% respectively. Peritoneal metastasis was significantly less severe in 5-Fu group,SU5416 group and combined group than that in control group(83% versus 46%,25% and 0) ( P

Objective To study the pathogenesis of osteoporosis in patients with liver cirrhosis following hepatitis B virus(HBV) infection(HBV-liver cirrhosis).Methods Bone mineral density(BMD) was measured by NM-300 sigle-energy X-ray acsorptiometry system for 61 patients with HBV-liver cirrhosis and 30 age-matched healthy controls.Serum levels of calcium regulatory hormones(CRH),1,25-dihydroxycholecalciferol [1,25(OH)_2D_3],parathyroid hormone(PTH),calcitonin(CT),osteocalcin(BGP),interleukin-1?(IL-1?),interleukin-6(IL-6) and tumor-necrosis factor-?(TNF-?),and urine level of crosslaps were measured in these patients and controls.Patients with HBV-liver cirrhosis were divided into two groups,osteoporotic and non-osteoporotic,based on their BMD in the ulna and radius,for comparison.Results BMD of the ulna and radius in patients with HBV-liver cirrhosis were significantly lower than those in controls.Serum levels of 1,25(OH)_2D_3 and BGP in patients with HBV-liver cirrhosis were significantly lower than those in controls,and much lower in osteoporotic group than that in non-osteoporotic one.While urine level of crosslaps increased significantly in patients with HBV-liver cirrhosis than in controls, much more increased in the those with osteoporosis than those without osteoporosis.Serum level of 1,25(OH)_2D_3 correlated with serum levels of BGP and BMD of the ulna and radius.Urine level of crosslaps correlated inversely with BMD of the ulan and radius in osteoporotic patients,but not in non-osteoporotic ones.Serum levels of IL-1?,IL-6 and(TNF-?) and urine level of crosslaps increased significantly in patients with HBV-liver cirrhosis than in controls,as well as increased significantly in those with osteoporosis than in those without osteoporosis.Serum levels of IL-1?,IL-6 and TNF-? and urine level of crosslaps correlated inversely with BMD of the ulna,particularly more significantly in those with osteoporosis than those without osteoporosis.Conclusions Two factors,less osteogenesis and more osteolysis,existed in patients with HBV-liver cirrhosis.Serum level of 1,25(OH)_2D_3 and serum levels of IL-1?,IL-6 and(TNF-?) played an important role in weakened bone formation and in increased bone resorption,respectively.Adequate supplementation of vitamin D_3 and reducing serum levels of IL-1?,IL-6 and TNF-? may be very important for prevention and treatment of hepatic bone disease.

Objective To investigate the predictive value of mild renal insufficiency on the endpoint events in patients with acute coronary syndrome (ACS).Methods A total of 552 patients with ACS were enrolled in the present study.According to the levels of estimated glomerular filtration rate (eGFR),patients were divided into two groups,normal renal function (eGFR≥90 ml · min-1 · 1.73 m-2) and mild renal insufficiency (60≤eGFR ＜90 ml · min-1 · 1.73 m-2).The primary and secondary events were collected and analyzed through the present prospective follow-up study.Results The patients in mild renal insufficiency group had a higher incidence of the primary endpoint events than normal renal function group [31 cases (12.6％) vs 15 cases (4.9％),P =0.001].There was no difference of the secondary endpoint events incidence in the two groups.The incidence rate of all-cause mortality [8.9％ (22 cases) vs 2.2％ (7 cases),P ＜0.001] and cardiac death [6.5％ (16 cases) vs 1.3％ (4 cases),P =0.001] was higher in mild renal insufficiency group,but there was no statistical difference of incidence rate of no fatal stroke and myocardial infarction in the two groups.The results of COX regression analysis showed that the incidence of primary endpoint events in patients with mild renal dysfunction was 2.265 folds (95％ CI 1.076-4.771,P=0.031) of patients with normal renal function.Further analysis indicated that the predictive value of mild renal insufficiency was only for all-cause mortality (HR 3.118,95％ CI 1.197-8.125,P =0.020),not for heart failure and revascularization.According to the Kaplan-Meier curves results,the incidences of the primary endpoint events (P =0.004) and all-cause mortality (P =0.001) were higher in mild renal insufficiency group than in normal renal function group.Conclusion Mild renal insufficiency has important predictive value for primary endpoint events in patients with ACS.

Objective To investigate treatment of meditation training for elderly patients with cogni-tive disorder recovering from operation for valvular heart disease( VHD) . Method 67 elderly patients who were up to the inclusion criteria were divided into experiment group( n=34)and control group( n=33),by dropping coins according to the admission time.Both of the two groups accepted regular health education and mental nursing.Besides,the experiment group accepted meditation training 5 times a week. Montreal Cogni-tive Assessment (MoCA) was used to evaluate cognitive function before and after the treatment. Results ( 1) Ridit analysis showed the intervention effect of the experimental group was better than that of the control group( R=2.12, t=-2.48, u=0.02),and the difference was statistically significant(P<0,05).The total effec-tive rate of experiment group is 90.32%,while the rate of control group is 62.89%. (2)The score of MoCA for the experiment group(25.79±1.23)was higher than that of the control group(23.85±1.82)after 6 weeks intervention,and the difference was statistically significant( t=5.14,P<0.01).(3) The score of MoCA of the experiment group before the intervention (23.91±2.22)was lower than after 6 weeks intervention(25.79±1. 23),and the difference was statistically significant( t=-4.30,P<0.01).Conclusion Meditation training can effectively improve cognitive function of elderly patients recovering from operation for VHD.

Objective:In order to prevent tracheostomal stenosis (TSS) instead of laryngectomy cannulas after total laryngectomy, Nickel\|Titanium shape memory alloys(NI\|SMA) stents in tracheostome were produced and applicated in clinic. Methods: The diameter of NI-SMA is 0.8mm, and Ni 50%, Ti 50%. The shape of the Ni\|SMA stent is the two\|threeth of circumference and its diameters are 18mm, 19.5mm, 21mm. The stents were implanted between the first and the second tracheal cartilage ring of the stump in twenty\|two patients with advanced laryngeal carcinoma or hypopharyngeal carcinoma or esophagul carcinoma in neck. All the patients were free of laryngectomy cannulas after operation. Results: Nieteen patients healed at one stage. Infections after operation were seen in three cases. Eight patients received radiotherapy after total laryngectomy. The NT\|SMA stent did not influence radiotherapy after operation. The TSS occured in six of the patients. A simple procedure named “doughnut” for widening stenosis was performed successfully with an electric cautery knife in all the patients with tracheostomal stenosis after operation. Conclusions: The results suggested that the NT\|SMA stents can prevent from traheostenosis instead of metal laryngectomy cannulas after total laryngectomy.
