Objective To optimize the RP-HPLC procedure for the determination of aristolochic acid. Method Different extraction solvents and methods have been screened to get the most efficient way for sample preparation. The influence of different mobile systems on quantitation were compared to choose an approprate mobile system for determination. Besides,the minimum limits of different detecting waves were measured to give the method to detect trace amount of aristolochic acid. Result Refluxing with 70% methanol was better than other ways in sample preparation. Both methanol-1% acetic acid (70∶30) solution and 0.3% ammonium carbonate solution (pH=7.5)-acetonitrile (75∶25) with wavelength of 250 nm and 319 nm can be used for quantitation while 0.3% ammonium carbonate solution (pH=7.5)-acetonitrile (75∶25) with wavelength of 224 nm for trace detection. The minimum detectable amount was 0.02 ng. Conclusion The method established can be applied to determinate aristolochic acid and detect trace amout exactly.

Objective To investigate the expressions of tetraspanin CO-029 in intrahepatic cholangiocarcinoma (ICC) and to find out their clinical significance.Methods RT-PCR and western blot were used to detect the expressions of CO-029 in ICC and their matched para-tumorous tissues from 20 patients with ICC,as well as in the HCCC-9810 cell lines.The expressions of CO-029 were further detected via tissue microarray (TMA) in the pathological specimens of 40 patients with ICC.Correlations between the expressions of CO-029 and the clinicopathologic features and prognosis were analyzed.Results A high level of CO-029 was detected in the 20 patients with ICC and the HCCC-9810 cell lines via western blot and RTPCR.Moreover,the expression levels of CO-029 in the ICC tissues were higher than the matched para-tumorous tissues (P ＜ 0.05).TMA detection revealed the positive expression rate of CO-029 to be 65％ (26/40).The expression level of CO-029 was much higher in the early recurrence group (Time to recurrence,TTR ＜ 1 year) than the non-recurrence group (TTR≥ 1 year).On analysis,the correlations were significant between the expressions of CO-029 and tumor encapsulation,hilar lymph node metastasis,TNM stage and prognosis (P ＜0.05).Conclusions CO-029 was highly expressed in ICC.It had close correlations with recurrence,metastasis and prognosis of patients with ICC.

Objective To compare the performance of Lung Imaging Reporting and Date System (Lung-RADS)with National Lung Screening Trail (NLST)in pulmonary nodules screening.Methods 1 5 3 patients with pulmonary nodules were analyzed retro-spectively,including,baseline screening and after baseline screening.We compared the sensitivity,false-positive result rate,positive predictive value,and negative predictive value in two methods of screening.Results In baseline screening of all patients with pulmo-nary nodules,the sensitivity,false positive rate and positive predictive value and negative predictive value of Lung-RADS and NLST were 83.9%,13.2%,6.5%,99.7% and 92.5%,26.9%,3.8%,99.8% respectively.In after baseline screening,the sensitivity, false positive rate and positive predictive value and negative predictive value were 79.6%,5.5%,11.5%,99.8% and 93.5%,22.8%, 3.5%,99.9% respectively.Conclusion Lung-RADS classification can reduce the false positive rate in screening of pulmonary nod-ules,which reduced the screening of lower risk nodules.

Objective To study the effect of Tspan 8 on metastasis and invasion of human hepatocellular carcinomas(HCC).Methods RT-PCR and western blot were used to detect the expressions of Tspan 8 in HCC cell lines,HCC and matched nontumorous tissues.The expression of Tspan 8 was then down-regulated by LV/GFP/Tspan 8 in HCC cells.The expressions of Tspan 8 mRNA and protein were determined by RT-PCR and Western blot assay,respectively.The proliferation was examined by MTT,the expression of AMDM12 was assessed by Western blot,and the invasion ability of HCC cells was evaluated by transwells.Results A high level of Tspan 8 was found in high metastatic potential HCC cells,and the expression of Tspan 8 in HCC tissues was much higher than that in the matched nontumorous tissues. Down-regulation of Tspan 8 had no influence on the proliferation of HCC cells (P＞0.05),while it inhibited the expression of ADAM12 and the invasive ability of HCC cells (P＜0.01,P＜0.01 respectively).Conclusion Tspan 8 played an important role in invasion and metastasis of human hepatocellular carcinomas and down-regulation by LV/GFP/Tspan 8 inhibited the invasiveness of human hepatocellular carcinoma cells.

Objective To investigate the effect of occult HBV infection (OBI) on carcinogenesis of cryptogenic hepatocellular carcinoma.Methods Samples of hepatocellular carcinoma (HCC) and pericarcinomatous tissues obtained after hepatectomy from January 2011 to November 2013 at the Third Affiliated Hospital of Sun Yat-Sen University were collected.They were divided into two groups:the cryptogenic HCC group (the CH group,n =26) and the HBV related HCC group (the HH group,n =40).These samples were compared with the normal liver tissues obtained in 30 patients.HBV DNA was identified by the nested polymerase chain reaction and the immunohistochemical method was taken to examine the hepatitis B virus X protein (HBx) and Yes-associated protein (YAP) expressions.Results OBI was identified in 20 (77.8％) cryptogenic HCC patients and 8 (26.7％) in the control group.There was a significant difference between the two groups (x2 =14.072,P ＜ 0.05).HBV DNA was detected in all the HBV-related HCC patients.The HBx protein expression was mainly located in the cytoplasm of liver cells and liver cancer cells,but YAP was expressed in the nucleus.Both of them showed diffuse brown or tan particles.In the HH group and the CH group,the positive expression rates of HBx protein in the tumorous tissues were 80.0％ and 90.0％,respectively,and 85.0％ and 82.5％ in the nontumorous tissues,but only in 40.0％ in the control group.The positive expression rates of YAP in the tumorous tissues were 65.0％ and 67.5％,respectively,15.0％ and 20.0％ in the nontumorous tissues,respectively,but only in 12.5％ in the control group.The HBx expression in the cancerous tissues and para-cancerous tissues of the HH group and the CH group showed no significant difference (P ＞ 0.05),but the YAP expression in the tumor tissues was significantly higher than that in the nontumorous tissues (P ＜ 0.05).The HBx and YAP expressions in the HH group were comparable to the CH group (P ＞ 0.05).However,their expressions in the cancerous tissue of the HH group and the CH group were significantly higher than in the normal liver tissues (P ＜ 0.05).Conclusion A high prevalence of HBV infection was observed in HBsAg-negative HCC and the high expressions of HBx and YAP might be involved in the process of cryptogenic hepatocellular carcinoma.

Objective To explore the mechanism of the experimental periodontitis and initial periodontal therapy on insulin resistance of obese rats associated with periodontitis.Methods Blood samples were collected from SD rats of obese group,periodontitis associated with obese group,periodontal therapy group and control group.Body index,data about insulin resistance and Observed pathological changes were calculated.Results Comparison of four groups:more severe insulin resistance and islet structural dysfunction was observed in obesity with periodontitis group than that of group with obesity alone.After periodontal therapy,inflammation and insulin resistance may be improved.Results from pathological specimens also supported this result.Conclusions The periodontitis with obesity can enhance the inflammatory state of obesity and cause the deterioration of insulin resistance.The initial periodontal treatment can relieve the inflammation of obesity with periodontitis and improve the resistance of insulin.It may be the reason of insulin resistance when obesity with periodontitis that the signaling pathways of IRS-1 and IRS-2 blocked,and PDX-1,GK,GLUT and other protein expression inhibited.

The authors reviewed the practice of integrated health care delivery system( IDS) at home and abroad, and based on experiences of collaborations between medical service institutions in Zhejiang province,proposed the strategic positioning,responsibilities and service innovation of urban public hospitals in a regional medical service system. It is held that the direction of China′s health care reform should move towards IDS in the future,and such hospitals should play an active role in the process via integration of its own resource and provide multi-level,diversified services for the regional health care system.

Objective To investigate the role of transmembrane protein C0-029 in epithelial mesenchymal transition (EMT) induced by tumor necrosis factor alpha (TNFα) of intrahepatic cholangiocarcinoma (ICC) cells.Methods RT-PCR and Western blot were conducted to detect the CO-029 expression in ICC cells and tissues.The effect of CO-029 silencing by lenti-virus on EMT induced by TNFα was investigated.Western blot and mass spectrometry after immunoprecipitation were used to confirm whether TNFαR1 can directly or indirectly bind with CO-029 to form complexes in ICC.Results Differential expression of CO-029 was observed in ICC cells and tissues.The expression of CO-029 was significantly reduced by lenti-viral interference in ICC cells,resulting in the failure of TNFα to induce EMT.TNFαR1 in ICC could directly or indirectly form complexes with CO-029.Conclusion CO-029 mediates TNFα/TNFαR1 induced EMT in ICC,which might play an important role in the invasion and metastasis.
