Objective To investigate the discharge outcome and its clinical influential factors of acute poisoning in children, and to provide the clinical references for prevention. Methods Questionaire about acute poisoning in children made by the research group,the hospitalized children and the influential factors were analyzed according to the outcome. Results Among 168 cases of acute poisoning hospitalized children,the curative rate was 80.95%, 16 cases(9.52%) were improved,6 cases (3.57%)were quitted,1.20% was ' not curative' and 4. 76% died. The factors including age,treatment time, route of entry, varieties of poison, medical examination of admission were statistically associated with the discharge outcome.Conclusion The outcome can be improved through an intensive nurse of the children under the age of three and early treatment. The cases who were not poisoned by the invasion of gastrointestinal tract,paraquat poisoning,and those with abnormalities of breathing, pupilla, awareness in medical examination of admission would have poor discharge outcomes, and should be monitored closely and treated timely.

Objective To understand the clinical features of peripheral cholangiocarcinoma (PC) developed against the background of hepatolithiasis. Methods Between 1995 and 2002, a total of 11 PC patients with definite history of hepatolithiasis were treated surgically in our hospital. The diagnosis, treatment and prognosis of this clinical entity were retrospectively analyzed. Results Peripheral cholangiocarcinoma occurred in 5 1% of patients with hepatolithiasis in this group and the tumor was located in the left lobe in 7 (64 7%) cases. All patients underwent laparotomy, with diagnosis established preoperatively in 3 (27 2%) cases and intraoperative diagnosis was missed in 2 (18 1%) cases. Radical resections were performed in only 3 (27 2%) cases. The overall operative morbidity and mortality were 72 7% and 9 1% respectively . Infection was the main postoperative complication. The postoperative 1 and 2 year survival rate was 33 3% and 11 1% respectively. Conclusions Cholangiocarcinoma may develope in patients with a history of hepatolithiasis. The prognosis of PC is still poor because of the difficulty to achieve early diagnosis and radical resection.

Objective To evaluate the treatment modalities for local recurrent periampullary carcinoma. Methods From January 1997 to May 2007, 23 patients with local recurrent periampullary carcinoma underwent different therapy. The recurrent tumor was resected through laparotomy in 3 cases and the unresectable tumors were treated with radiofrequency ablation(RFA) in 5 patients. In 10 patients and 5 patients respectively high intensity focused ultrasound ( HIFU ) and regional chemotherapy ( RC ) were performed. Results The resection rate for local recurrent periampullary carcinoma was 13% in this group, 2 patients have survived for 10 months and 13 months respectively after reoperation while one patient achieved tumor-free survival for six months so far. The symptoms were alleviated to some extent in 20 patients treated with RFA, HIFU or RC. Conclusions Resection of local recurrent periampullary carcinoma may benefit a longer survival time, and the improvement of the quality of life. RFA, HIFU and RC are the alternative modalities for patients with unresectable tumors.

OBJECTIVE: To develop an ultra-high performance liquid chromatography-mass spectrometry method for the determination of glimepiride and its metabolites (M1) simultaneously in human plasma.

Background and purpose:Methylene tetrahydrofolate reductase (MTHFR) plays an important role in metabolism of folate and DNA methylation. This study aimed to investigate the relationship between methylene tetrahydrofolate reductase (MTHFR) C677T polymorphism and chemotherapy side effects in advanced non-small cell lung cancer (NSCLC) patients. Methods:A total of 100 patients with advanced NSCLC conifrmed by pathology were included into this study in Zhejiang Cancer Hospital from Jun. 2007 to May. 2009. All patients received the combined chemotherapy of platinum drug and gemcitabine. MTHFR genotypes were determined by allele-specific-PCR technology. Results:In the 100 cases, genotype frequency of MTHFR C677T T/T, T/C and C/C were 20%, 44%and 36%, respectively. Compared with patients of T/T and T/C genotype, patients of C/C genotype were correlated with decreased rate of thrombocytopenia to chemotherapy (P=0.039). No signiifcant differences were observed concerning gastrointestinal toxicity. Conclusion:MTHFR C677T gene polymorphism can be used to predict the adverse reactions to platinum-based chemotherapy in patients with advanced NSCLC.

Objective To compare the efficacy and the side-effect of three different ways in treating the patients with malignant pleural effusion. Methods 98 patients histologically proved malignant pleural effusion were randomly divided into three groups, bleomycin group(BLM), bleomycin with mycobacterium group( BLM + UTL) and blemycin with intertleukino2 ( BLM +IL). 31 patients were treated with bleomycin intrapleural injection in BLM group,32 patients were treated with bleomycin and Utilin's(mycobacterium) intrapleural injection in BLM + ULL group and 35 patients were treated with bleomycin and intertleukin-2 intrapleural injection in BLM + IL group. The therapeutic efficacy, change of performance and side effects were compared among the three groups after one period of treatment. The changes of CEA and TNF in the pleural effusion were examined before and after treatment. Results The therapeutic efficacy and performance improvement were higher in BLM+UTL and BLM+IL group than that of BLM group(P＜0. 05) ,the pleural CEA of post-treatment in three groups were lower than that of pre-treatment(P＜0.01) ,the CEA after treatment in BLM+UTL group and BLM+IL group was lower than that of BLM group(P＜0. 01,respectively). The pleural TNF of post-treatment in BLM+UTL and BLM+IL groups was higher than that of pre-treatment(P＜0. 01 ) in BLM group. The pleural TNF of post-treatment in BLM+UTL and BLM+IL group was higher than that of BLM group ( P＜0. 01 ). Conclusion Intrapleural injection of mycobacterium with bleomycin or interlekin-2 with bleomycin has better efficacy than using bleomycin only in treating malignant pleural effusion.

Objective To observe the efficacy,toxic side effects, survival time and quality of life (QOL) of vinorelbine and vinorelbine plus carboplatin in elderly patients with stage Ⅲ b/Ⅳ non-small cell lung cancer(NSCLC).Methods Eighty patients aged 65 years or over with stage Ⅲ b/Ⅳ non-small cell lung cancer were randomly divided into two groups.One group was treated with vinorelbine (vinorelbine 25 mg/m2 iv d1,8, repeated every 21 days), the other group was treated with vinorelbine plus carboplatin(vinorelbine 25 mg/m2 iv at day 1 and 8 and earboplatin AUC5 iv at day 1, repeated every 21 days).Results The response rate(RR), median survival time(MST) and 1-year survival rate were 35.0%, 9.0 months and 35.0% in vinorelbine group and were 42.5%, 10.0 months and 37.5% in vinorelbine plus carboplatin group respectively.There was no significant difference between two groups(χ2 =0.296,P=0.586).The incidences of Ⅲ-Ⅳ degree granulocytopenia (χ2 =7.168,P=0.014), Ⅲ-Ⅳ degree thrombocytopenia (χ2 = 5.165,P=0.048)and Ⅲ-Ⅳ degree nausea and vomiting (χ2 =6.275, P =0.025) were significantly higher in the combined chemotherapy group than in the vinorelbine treatment group.The scores of lung cancer symptom scale (LCSS) of appetite loss(χ2 =2.600,P=0.011), fatigue(χ2 =3.169,P=0.002) and pain(χ2 =2.257,P=0.027) were more higher in the vinorelbine treatment group than in the combined chemotherapy group.Conclusions Vinorelbine regimen is effective, well tolerated and more favorable for the elderly NSCLC patients.

Objective: To investigate differentially expressed protein profiles in B16-F10 grafted melanoma and its metastasis in the lung in order to identify molecular markers of melanoma metastasis. Methods: Differentially expressed proteins in B16-F10 grafted melanoma and its metastatic lesion in the lung were isolated and identified by fluorescence two-dimensional differential gel electrophoresis(2D-DIGE)coupled with matrix assisted laser desorption ionisation time-of-flight mass spectrometry(MALDI-TOF-MS).Some of identified proteins were further confirmed by Real-time PCR analysis. Results: High resolutional images of differential gel electrophoresis were obtained and 9 of 30 differentially expressed proteins (IRatiol≥2,P<0.01)were identified by MALDI-TOF-MS.The expression of Myoglobin(MB),vimentin(VIM),phosphoglycerate kinase 1(PGK1),Triosephosphate isomerase(TPI or TIM),heavy-chain binding protein(BiP),α-enolase,β-actin,γ-actin,and laminin-binding protein were up-regulated in the experimental group compared with the control group.These proteins were involved in the cytoskeletal formation,glycolysis and so on.Real-time PCR analysis showed up-regulation of mRNA expression of PGK1 and TPI in the experimental group(P=0.001 and 0.003),which was in consistent with the resuits of proteomic analysis. Conclusion: A variety of abnormally expressed proteins contribute to the metastasis of mice melanoma.Glycolytic enzymes PGK1 and TPI may be involved in this process.
