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 explore the relationship between serum placental growth factor (PLGF) and carotid atherosclerosis (CAS) in patients with type 2 diabetes mellitus (T2DM ). Methods Serum PLGF were determined by ELISA in 53 patients with T2DM ,who were divided into T2DM without carotid plague (T2DM group ,n= 27) and T2DM with carotid plague (T2DM + CAS group ,n= 26). Fasting plasma glucose (FPG) ,glycosylated hemoglobin A1c (HbA1c) and some other metabolic variables were also measured. The results were compared to those of 27 healthy controls (NC group). Results Serum PLGF levels were significantly higher in T2DM group and T2DM + CAS group than in NC group (P<0.01). T2DM+CAS group showed significantly higher serum levels of PLGF compared to that of T 2DM group(P<0.01).Correlation analysis showed that serum PLGF was positively correlated with TC ,LDL‐C , hsC‐RP and IL‐6 in T2DM patients (P<0.01). Similarly ,multiple regression analysis showed that LDL‐C and IL‐6 were the independent factors of serum PLGF level (P<0.05). Furthermore ,Serum PLGF was positively associated with carotid plague. Conclusion PLGF is positively related with chronic inflammation factors in T2DM patients. Serum PLGF may play an important role in the occurrence and development of carotid atherosclerosis and other macroangiopathy in T 2DM.

Objective To investigate the effect of the secondary transurethral resection in the treatment of non-muscle invasive bladder cancer(NMIBC).Methods 186 cases with NMIBC were randomly divided into control and experimental groups,both groups were treated by transurethral resection of bladder tumor(TURBT),and experimental group received the secondary TURBT after 4 weeks of the first TURBT.The recurrences of two groups were compared.Results The recurrence rate was significantly lower in experimental group than in the control group(13.8％ vs.37.0％,x2 =13.17,P＜0.05).The recurrence number of the original site was significantly less in experimental group than in the control group(x2 =8.35,P＜0.05).Conclusions The secondary TURBT plays a positive role in NMIBC recurrence.

ObjectiveTo synthesize metal complex that exhibits superoxide dismutase (SOD)-like activity and determine its structure.MethodsThis chemical compound was synthesized by means of reflux in laboratory.Its structure was examined by infrared spectra (IR),nuclear magnetic resonance hydrogen spectra(H-NMR) and mass spectra (MS).The activity of the SOD was determine by xanthine oxidase (XOD).ResultsThe IR indicted that this complex showed a typical absorption band of -OH,C=N and benzene. The H-NMR reveals the existence of metal ion manganese (Mn3+ ,paramagnetic). The molecular weight was 365, which was obtained by EI-MS analysis. And this complex showed SOD-like activity.ConclusionA metal complex with low molecular weight and SOD-like activity has been synthesized.

Objective To study the protective effects of the compound with low molecular weight of anti free radical on brain ischemic and hypoxic injuries in rats.Methods The model of brain ischemic and hypoxic injuries in rats was established by unilateral carotid artery ligature just for 2 h. The compound was injected 30 minutes after the rats act on hypoxic state (10% O2+90%N2) for 1 h. Then the serum of rats was separated and the value of the superoxide dismutase (SOD) activity and malondiade (MDA) were determined, and the pathological changes were observed in brain tissue.Results Compared with rats in the model group, the compound decreased the concentrations of MDA in serum (P<0.05), and raised the level of SOD (P<0.05) significantly in therapy group. Otherwise, the pyramidal cells remained organized order, with only a few cells degenerated occasionally in rats of therapy group. Conclusion The compound has SOD like activity. It can scavenge the free radical and inhibit peroxidation of lipid, so it can prevent brain cells from the damage.

Objective To investigate clinical characteristics of the multi-center breast DCIS (ductal carcinoma in situ), in order to improve the rate of early diagnosis. Methods Clinical data of 23 multi-center breast DCIS patients admitted and operated on from September 2003 to February 2009 at our department were retrospectively reviewed. Results There were 4 cases associated with nipple discharge,and 18 cases with preoperative negative physical examination (78%). In the preoperative examination within 6 months, the positive rate of mammography was 90% mainly characterized by the existence of diffuse and multiple small calcifications. The positive rate of MRI was 25%, B ultrasound had no positive findings. The patients that were confirmed multi-center breast DCIS by intraoperative frozen section examination received mastectomy and ipsilateral axillary L1, L2 lymph node dissection. Conclusion The diffuse and multiple small calcification is one of early clinical characteristics of multi-center breast DCIS. Although the disease has a wide range of lesion, it still is an early tumor, and has a favourite prognosis after comprehensive treatment.
