Objective To investigate the incidence of C-shaped root canal systems in mandibular second perma?nent molar of patients in the First People’s Hospital of Yunnan Province, and compare the success rate between one-and two-visit root canal treatment. Methods Two hundred and sixty mandibular second molars were recruited from the pa?tients in the department of endodontics of our hospital, and teeth with C-shaped root canal were categorized by using radio?graphic classification criteria and the modified Melton’s method. Teeth with C-shaped root canal systems were then random?ly divided into two groups to receive one-or two-visit root canal treatment, and success rates of 6-month post-operation were compared between two groups. Results Eighty out of 260 mandibular second molars exhibited C-shaped canals (30.77%). Radiographic examination showed that 25 teeth belonged to typeⅠ(31.25%), 32 teeth typeⅡ(40.00%) and 23 teeth typeⅢ(28.75%) in two groups. As for modified Melton’s method, the incidence rates were 21.25%, 48.75%, 16.25%and 13.75% for C1,C2,C3a and C3b, respectively, while C4 was not found. The success rates were 78.94% (30/38) and 81.08%(30/37) for A group and B group, respectively, with no statistically significant difference between two groups ( 78.94 vs 81.08, P>0.05). Conclusion Results indicate a frequent incidence of C-shaped root canal system of mandibular per?manent second molars in our hospital. One-visit root canal treatment is an effective way for treating C-shaped canals in man?dibular permanent second molar.

Somatostatin,a cyclopeptide hormone,is generally distributed in vivo.Some studies have indicated that somatostatin can reduce proinflammatory cytokine in hepatic stellate cells and extracellular matrix,and inhibit their proliferation and contraction,promote their apoptosis.It can also regulate the function of Kupffer cells,influence the homing of hepatic stem cells.Somatostain has therapeutic effect on liver fibrosis,especially on the liver fibrosis caused by schistosoma mansoni.

Objective To investigate the dynamic change of serum high sensitive C-reactive protein (hsCRP) after carotid artery stenting (CAS) and its correlation with in-stent restenosis.Methods The serum hsCRP levels were determined before procedure,at 12 hours,7 days,3 and 6 months after procedure in patients who underwent CAS in the Department of Neurology,Jinling Hospital,Nanjing Their cerebral angiography was reexamined and whether there was in-stent restenosis after 6 months was observed.Results Eighty-four patients treated with CAS were included in the study.Fifteen (24%) had in-stent restenosis after CAS.The stenosis in 3 of them was > 50%,and the stenosis m 12 of them was 30% to 50%.The serum hs-CRP levels in all patients after procedure were significantly higher than those before treatment (all P < 0.01 ),and they were significantly lower at 6 months after procedure than before treatment (all P <0.01).Univariate analysis showed that the proportion of diabetes in the restenosis group was significantly higher than that in the non-restenosis group (P<0.01).At 7 days (8.83 ± 1.94 mg/L vs.6.77 ± 1.63 mg/L,t =14.398,P=0.044),3 months after procedure (8.26 ± 1.32 mg/L vs.4.58 ± 1.45 mg/L,t =17.569,P =0.008) and 6 months after procedure (7.04 ± i.07 mg/L vs.3.12 ± 1.28 mg/L,t =21.867,P =0.003),the serum hs-CRP levels in the restenosis group were significantly higher than those in the non-restenosis group,and the difference of the serum hs-CRP level (△ hs-CRP) before procedure and at 6 month after procedure was significantly lower than that in the nonrestenosis group (0.85 ± 0.13 mg/L vs.4.89 ± 0.94 mg/L,t =16.987,P =0.000).Multivariate logistic regression analysis showed that /hs-CRP (odds ratio [ OR] 2.392,95% confidence interval [ CI] 1.538 -3.513; P =0.009) and diabetes (OR 1.840,95% CI 1.372 -2.241; P =0.023) were the risk factors for instent restenosis.Conclusions The serum hs-CRP level increased significantly at 12 hours after CAS procedure,and then decreased continuously.At 6 months after procedure,the more decrease of the serum hs-CRP level,the lower risk of occurring in-stent restenosis was.

A method was evaluated for determination of twenty-one doping (including nandrolone, boldenone and methandienone) in human urine by gas chromatography-high resolution mass spectrometry. Samples were prepared by liquid-liquid extraction, concentrated, TMS derivatization and limit of detection at ng x mL(-1) by MID/GC/HRMS. According to the code of the World Anti-Doping Agency (WADA), precision and recoveries of the procedure were evaluated by replicate analysis (n = 6), the recoveries in the range of 66%-103%, with the RSD below 10.0%. The precision within the day of the method with three different concentrations was also determined RSD were less than 9.5%, 10.0% and 9.7%.

OBJECTIVE: To investigate the effects of different concentrations of curcumin on secretion of adiponectin (APN) and interleukin-6 (IL-6) in human adipose tissues cultivated in vitro. METHODS: Seven male patients with kidney stones were admitted. Abdominal subcutaneous adipose tissue and perirenal adipose tissue were collected from the operating-patients, and were cultivated with different concentrations of curcumin (10 and 100 microg/ml) in vitro. The contents of APN and IL-6 in the culture medium of adipose tissue cells were measured by enzyme-linked immunosorbent assay (ELISA) after they were cultured for 6 and 24 hours. RESULTS: Compared with the blank control group, the content of APN in the adipose tissue culture medium was increased by 100 microg/ml curcumin (P<0.05) after 6-hour culture, and the content of IL-6 was significantly decreased by 100 microg/ml curcumin after 6- and 24-hour culture (P<0.05). CONCLUSION: 100 microg/ml curcumin can increase APN secretion and decrease IL-6 secretion in human adipose tissues cultivated in vitro.
