OBJECTIVETo evaluate the applicability of immune-related response criteria (irRC) in treating non-small cell lung cancer (NSCLC) by Chinese medicine (CM).

METHODSTotally 97 stage III a-IV NSCLC patients were predominantly treated with comprehensive CM. Curative effects were evaluated by three methods such as Response Evaluation Criteria in Solid Tumors (RECIST), Oncologic Curative Effect Evaluation Criteria of Chinese Medicine in Solid Tumor (draft, abbreviated as CM criteria), and irRC. The correspondency and consistency between irRC, RECIST and CM criteria were analyzed and compared. The objectivity of irRC in evaluating curative effect of Chinese medical treatment for NSCLC was assessed.

RESULTSThe correspondency rate of irRC to RECIST was 59. 79% with Kappa value of 0. 379 (U test, P <0. 01). The two criteria had certain correspondence, but with an unsatisfactory consistency. The correspondency rate of irRC to CM criteria rate was 83. 51% with Kappa value of 0.751 (U test, P <0. 01). The two criteria had good correspondence and consistency.

CONCLUSIONSCM criteria had good consistency with CM criteria in evaluating curative effect for Chinese medical treatment of advanced NSCLC. Its results could objectively reflect features and advantages of CM for treating advanced NSCLC.

OBJECTIVETo explore effects and possible mechanisms of curcumin on hypoxia induced epithelial-mesenchymal transition (EMT) in hepatocellular carcinoma cell line HepG2.

METHODSHepG2 cells were divided to 3 groups, i.e., the normal control group, the CoCl2 group, and the CoCl2 plus 10 micromol/L curcumin group. The proliferation of HepG2 was determined using MTT assay. The migration of HepG2 was detected by wound healing assay.The mRNA expression of hypoxia-inducible factor-1 (HIF-1alpha) was evaluated with real-time RT-PCR. The protein expressions of HIF-1alpha, epithelial-cadherin (E-cadherin), and vimentin were determined using Western blot.

RESULTSCompared with the normal control group, the proliferation and migration of HepG2 cells under CoCl2-induced hypoxia significantly increased, the expression of HIF-1alpha was up-regulated, and the expression of E-cadherin protein was obviously down-regulated, and the expression of vimentin significantly increased (all P < 0.05). Intervention by curcumin significantly inhibited the proliferation and migration of hypoxic HepG2 cells, and expressions of HIF-1alpha and vimentin decreased, and the expression of E-cadherin was up-regulated, showing statistical difference when compared with those of the CoCl2 group (P < 0.05). There was no statistical difference in HIF-1alpha mRNA expression among the 3 groups (P > 0.05).

CONCLUSIONCurcumin could reverse the proliferation and migration of HepG2 cells under CoCl2-induced hypoxia condition, which might be associated with inhibiting up-regulated expressions of HIF-1alpha protein and EMT.

OBJECTIVETo study the changes of adenosine diphosphate (ADP)-induced platelet aggregation rate, and evaluate the effects of Maixuekang Capsule (MC) on the platelet aggregation rate, high-sensitive C-reactive protein (hs-CRP) and the long-term prognosis in patients with acute coronary syndrome under percutaneous coronary intervention (PCI).

METHODSTotally 236 inpatients with acute coronary syndrome under PCI, who successively received PCI from July 2008 to June 2010, were randomly assigned to the routine treatment group (RTT, 120 cases) and the MC treatment group (MKT, 116 cases). Besides routine medication, patients in the MKT group additionally took MC, 12 capsules daily for 12 successive months. The ADP-induced platelet aggregation rate and hs-CRP concentration were determined before PCI, 12 h and 30 days after PCI. In the meantime, the incidence of adverse cardio-/cerebrovascular events was recorded during the twelve-month clinical follow-up. Results Compared with before PCI, ADP-induced platelet aggregation rate and the serum hs-CRP concentration were significantly higher 12 h after PCI (P < 0.05). They were significantly reduced after 30-day treatment of MC, showing statistical difference when compared with those in the RTT group (P < 0.05). In the 12-month follow-up, the incidence of adverse cardio-/cerebrovascular events was significantly lower in the MKT group than in the RTT group (6.9% vs 12.5%, P < 0.01).

CONCLUSIONSADP-induced platelet aggregation function was significantly elevated after PCI, which was a predictive factor of poor coronary events. MC improved the long-term prognosis of patients with acute coronary syndrome possibly through inhibiting the platelet aggregation rate and the hs-CRP concentration.

Introduction:The 2010 targets of the China Hepatitis B Prevention Programme were a prevalence of hepatitis B surface antigen (HBsAg) less than 1.0% for children less than five years old and less than 6.0% for the total population. This survey assessed the prevalence of Hepatitis B infection in Lianyungang, Jiangsu province, China in 2009–2010.Methods:Multistage sampling was used with 2372 subjects among 17 selected villages. Blood specimen collection and testing by enzyme-linked immunosorbnet assay (ELISA) were completed using the following markers for hepatitis infection: HBsAg and antibody to HBsAg (anti-HBs); hepatitis B e antigen (HBeAg) and antibody to HBeAg (anti-HBe); and hepatitis B core antibody (total anti-HBc). The data were analysed with Epi Info, version 3.3.2.Results:The prevalence of HBsAg was 2.4% (95% Confidence Interval [CI]: 1.8–3.0; Adjusted Prevalence [AP] 2.9%); anti-HBs prevalence was 51.1% (95% CI: 49.1–53.1; AP 49.2%) and total anti-HBc prevalence was 41.7% (95% CI: 39.8–43.7; AP 45.5%). The prevalence of HBsAg and total anti-HBc positivity increased from young to older age groups, yet the prevalence of anti-HBs positivity decreased from young to older age groups (P< 0.001 for all). There was no difference in the prevalences of HBsAg and anti-HBs among females and males (P= 0.108 and 0.089), but females had a higher prevalence than males for total anti-HBc positivity (P< 0.001). Discussion: This survey showed that in 2010 the prevalence of HBsAg among children aged less than five years was lower than the national target of 1.0% and that the prevalence of HBsAg for the total population was lower than the national target of 6.0%.

OBJECTIVESince late March 2009, a novel influenza H1N1 strain emerged in humans in Mexico and the United States. It has rapidly spread to many countries on different continents, prompting unprecedented activation of pandemic preparedness plans. The present study aimed to investigate the characteristics of children with the novel influenza A (H1N1) virus infection.

METHODTwelve cases with influenza A (H1N1) infection were diagnosed according to the criteria of the Center for Disease Control and Prevention (CDC) of China during 1 May to 15 July 2009 in the Pediatric Hospital of Fudan University were analyzed. Influenza A (H1N1) RNA was detected by RT-PCR in CDC Shanghai China.

RESULTAll the 12 children with the novel influenza A (H1N1) virus infection were imported cases, aged from 11 months to 14 years 7 months, 7 of whom were boys, 5 were girls. Five cases contacted closely with influenza A (H1N1) patients; 12 cases had fever and no vomiting or diarrhea; 7 had cough or runny nose or anorexia. One had shortness of breath. Of the 11 cases who could tell about symptoms correctly, 6 had sore throat, 3 had stomachache, and none had muscle pain. Two of the 12 cases had pneumonia, and the disease in 1 of them was fatal and needed intensive care. One case was isolated and treated at home. The 11 cases hospitalized were treated according to the guidance of influenza A (H1N1) diagnosis and treatment issued by the Ministry of Health of China. Ten hospitalized cases were treated with oseltamivir. All the cases recovered completely. The median length of hospital stay was 8.1 days (range, 6 to 16), and the time of negative test results of influenza A (H1N1) RNA from illness onset to collection of samples for viral testing was from 5 to 15 days.

CONCLUSIONSymptoms among children with the novel influenza A (H1N1) virus infection were classic and the majority of the cases we treated had a mild clinical course if they were isolated and treated promptly. Antivirals appears to have not had any major adverse effects. More data from different regions and large samples are needed to illuminate the characteristics of children with novel influenza A (H1N1) virus infection.
