Objective: To investigate the constituents of indole alkaloids in Ervatamia yunnanensis and their antiaddictive bioactivities. Methods: The preliminary alkaloids (TEYA) were extracted by 95 % EtOH from the stems of Ervatamia yunnanensis. TEYA was then purified by silica gel and Sephadex LH20 column chromatography repeatedly and its structure was identified with spectral analysis. The antiaddictive effects of these indole alkaloids were evaluated by Conditioned Place Preference (CPP) experiments. Results: Nine indole alkaloids were obtained and identified as: coronaridine (1) , voacangine (2), 3-R-ethoxycoronaridine (3), 3-S-ethoxycoronaridine (4), 19-epi-heyneanine (5), heyneanine (6), 19-epi-voacristine (7), coronaridine hydroxyindolenine (8) and 12-methoxyl-voaphylline (9). Among them voacangine (2) and 19-epi-voacristine (7) were effective in prevention and treatment of addiction induced by morphine in rats (n=8). Conclusion: Compounds 3, 4, 8, and 9 have been isolated from Ervatamia yunnanensis for the first time and coronaridine-type indole alkaloids are the main antiaddictive constituents of E. yunnanensis.

Objective　This study was To investigate the incidence rate of Cockett syndrome and relationship between Cockett syndrome and varicose veins and deep venous incompetence of the left lower extremities.Methods　73 patients(100 legs) with varicose veins of the lower extremities were investigated by descending deep venography and iliography preoperatively.Results　There were 35(47.9%) cases with abnormalities of the left common iliac vein (ALCIV)in all the cases.There were 31 cases with this conditions in the patients with varicose veins of the left or both lower extremity.While in the patients with varicose veins of the only right lower extremity,there were only 4 cases with ALCIV.In contrast,there was a significant difference between groups(χ2=9.8641,P=0.0017).In the patients with ALCIV,14 cases with Ⅲ or Ⅳ grade of deep venous incomptence were found, and only 6 cases with deep venous incompetence in the patients without ALCIV.There was a significant difference(χ2=5.3688,P=0.0205).Conclusion　Cockett's syndrome frequently occurs in varicose veins of the left lower extremity.There is a relationship between them.Cockett's syndrome might be one of the causes for the deep venous incompetence of the left leg.

Objective To assess the feasibility of laparoscopic hepatic lobe procurement for living donor liver transplantation. Methods The technique included pneumoperitoneum with CO2,ports placement, porta hepatis dissection, laparoscopic ultrasound mapping, mobilization of the liver,and transection of the parenchyma into right and left lobes. The vascular structures were stapled and sectioned just prior to removal of the specimen. Results Hepatic lobectomies were successfully performed laparoscopically in 9 adult pigs. One pig was dead due to bleeding in IVC and following gas embolism during the parenchymal transection. The operative time was 208±25 min. The duration of warm ischemia was 8 ± 2. 3 min. The blood loss was 313 ± 75 mL. The vascular and biliary structures were preserved to allow for subsequent transplantation. Conclusion Laparoscopic living donor procurement for liver transplantation in a porcine model is safe and feasible.

Acute lung injury(ALI) and acute respiratory distress syndrome(ARDS) are common,life-threatening causes of acute respiratory failure that arise from a variety of local and systemic insults.The pathogenesis of ALI/ARDS is complicated and not yet completely interpreted today.The role of altered coagulation and fibrinolysis in the pathogenesis of ALI/ARDS has been investigated.This review will summarize the current understanding of coagulation and fibrinolysis in human ALI/ARDS with emphasis on pathways that could be potential therapeutic targets.These pathways include the tissue factor pathway,the protein C pathway and modulation of fibrinolysis via plasminogen activator inhibitor-1.

Objective:To investigate the effect of methylphenidate on the ERP waveform of children with attention deficit hyperactivity disorder(ADHD) between responders and non-responders and it's psychological significance.Methods:ERP elicited by the continuous performance test were recorded before and under methylphenidate treatment in 28 ADHD children and their behavioral performance were collected simultaneously.Based on the behavioral results,the patients were divided into two groups:responders and non-responders.Results:After medcation,the responders' behavioral performance were significantly better,amplitude of NOGO-P3(30.24?10.78?v) were also larger than that of before treatment(20.34?11.42?v,P=0.04);No significant differences were found in the behavioral performance and NOGO-P3 amplitude before and after treatment(23.51?11.97?v/25.88?13.96?v,P=0.61) in the non-responders group.The amplitude of NOGO-N2 of the two groups did not have significant difference before and under methylphenidate treatment.Off medication,there were no differences between responders and non-responders.Conclusion:Methylphenidate can improve the ability of response inhibition in responders as well as increase the amplitude of NOGO-P3 of them.

Objective To analyze the risk factors of early renal damage in children with Henoch Schonlein purpura(HSP).Methods The clinical data of 196 children with HSP admitted to our hospital from April 2012 to January 2016 were analyzed retrospectively.They were divided into the renal damage group and non-renal damage group within 90 d after confirmed diagnosis.The related clinical data such as serum immunoglobulin and urinary microalbumin were compared between the two groups,and the risk factors of early renal damage in children with HSP were screened.Results There were significant differences between the two groups on age,joint symptoms,recurrent purpura,persistent rash,gastrointestinal bleeding and abdominal pain(with χ2 or t of 11.345,16.223,11.275,43.211,12.592,17.771,P<0.05).The white blood cell count,platelet count,immunoglobulin A(IgA) level and urinary albumin level also showed significant differences between the two groups(t=33.750,60.442,9.451,8.458,P<0.05).The multivariate regression analysis showed that the independent risk factors for early renal damage in children with HSP included age(OR=2.703),recurrent purpura(OR=2.721),persistent skin rash(OR=1.782),gastrointestinal bleeding(OR=11.472),abdominal pain(OR=2.046),IgA level(OR=1.221) and urine microalbumin(OR=3.214).Conclusion Age,recurrent purpura,persistent skin rash,gastrointestinal bleeding,abdominal pain,IgA level and urine microalbumin are closely related to early renal damage in children with HSP.

Objective To evaluate the clinical efficacy of thermo-chemotherapy and thermo-lipiodol embolization intreatment of primary hepatocellular carcinoma(PHC).Methods One hundred and sixteen cases of PHC were divided into three groups.Group A(38 cases)was treated with normal temperature chemotherapy and normal temperature lipiodol,Group B(40 cases)with thermo-chemotherapy and normal temperature lipiodol and group C(38 cases)with thermo-chemotherapy and thermo-lipiodol.Group B and group C were called the thermotherapy group.Results In the thermotherapy groups,the rates of tumor size reduction were significantly greater than those in the normal group.There were no significant different in the hepatic function tests among the three groups.The 6-,12-,18-,and 24-month survival rates of the normal group and thermotherapy groups were 97%,58%,39% and 18%,versus 99%,79%,57% and 36%,respectively.No significant differences were found in the rates of reduction of tumor size and survival rates between group B and group C.Conclusion Thermo-chemotherapy and thermo-embolization possess significant effect on PHC but without conspicuous damage to liver function.
