Objective: To learn law students' understanding of and demand for knowledge of forensic medicine,especially their attitude for autopsy and adjust the teaching reform in forensic medicine.Methods: Investigation was made by anonymous questionnaire in law undergraduates of 1999 and 2000 grades in Law College of Shantou University.Results: Almost all the students considered forensic medicine essential for themselves.The antitheist rate of the students in non-Chaoshan area(75.2%) was higher than that of the students in Chaoshan area(54.2%).57.4% of the students didn't want to join autopsy because of dread without obvious causes.93.3% of them thought that the autopsy should be taken by the legal medical experts.Conclusion: The law students prevalently enjoy the courses of forensic medicine,and they are more interested in the knowledge of forensic pathology.

Objective To evaluate the changes of platelet activity before and after anti-platelet treatment in pa?tients with coronary heart disease, and their responsiveness to clopidogrel through detecting the phosphorylation levels of va?sodilator stimulated phosphoprotein (VASP). Methods Twenty-eight cases of healthy people were selected as control group . Patients with chronic stable angina pectoris (CSA, n=95) were randomly divided into A (48 cases) group and B (47 cases) group,and were given clopidogrel 75 mg/d or 150 mg/d respectively;Patients with non ST segment elevation acute coronary syndrome (NST-ACS, n=67) were all given 300 mg loading dose of clopidogrel at the first time, then randomly divid?ed into C (33 cases) group and D (34 cases) group, and given clopidogrel 75 mg/d and 150 mg/d respectively. Blood were tak?en to examine the phosphorylation levels of serum VASP by ELISA before taking clopidogrel, at time point of loading dose and the fifth day of clopidogrel administration . Results Before treatment, phosphorylation levels of serum VASP were low?er in A, B, C, D groups than those in the normal control group(P<0.05). After treatment of clopidogrel for 5 days: ① In group A and group B ,phosphorylation levels of serum VASP did not change compared to that before treatment (P>0.05).②In group C and group D, phosphorylation levels of serum VASP were significantly increased at loading dose and the fifth day of clopidogrel administration than those before treatment (P<0.05), but there were no significant differences in phosphory?lation level of VASP was lower group between group C and group D after serum treatment (P > 0.05). Conclusion The phosphorylation level of serum VASP was lower in patients with coronary heart disease than that in normal control group. Clopidogrel can improve the phosphorylation level of serum VASP in NST-ACS patients .

BACKGROUND:With the development of industry and agriculture, organotin compounds have been widely used in China. Organotin compounds cause a common occupational poisoning. The toxicity of organotin was reported in animal studies; however the reports about human organotin intoxication are very rare. In this study we retrospectively analyzed the clinical manifestations of 15 organotin-poisoned patients who had been treated at our hospital from 2002 through 2007. METHODS:Fifteen patients with organotin poisoning were admitted to Sir Run Run Shaw Hospital Affiliated to Zhejiang University School of Medicine from 2002 to 2007. They were 9 males and 6 females, aged from 25 to 52 years. Clinical manifestations and Glasgow Coma Scales showed that the poisoning was mild in 4 patients, moderate in 6 and severe in 5. The severe patients were given glucocorticoid after hospitalization by intravenous guttae of 500 mg methylprednisolone for the first day, followed by 160 mg methylprednisolone per day for three days, and then 80 mg methylprednisolone per day for another three days. Potassium glutamate and sodium glutamate were intravenously dripped to reduce blood ammonia; intravenous guttae plus oral administration of potassium 9 g/day was used to correct intractable hypokalemia; sodium bicarbonate was used to correct metabolic acidosis, and sedatives were used to control spasm and twitch; mechanical ventilators were used in 4 patients with dyspnea. RESULTS:Most of the patients showed elevated level of blood ammonia, decreased level of blood potassium and metabolic acidosis, but some had demyelination changes shown by CT and MRI. Treatments included correction of metabolic acids, blood potassium and ammonia, and mechanical ventilation when necessary. For patients with injuries of the nervous system, glucocorticoids were given immediately after hospitalization. These patients showed intractable hypokalemia and metabolic acidosis during the treatment. Forteen patients recovered completely without long-term side-effect. One patient in the aphasiac stage restored the linguistic capacity during a 6-month follow-up. CONCLUSIONS:Elevated level of blood ammonia, decresed level of blood potassium, and metabolic acidosis are common in patients with organotin poisoning. Demyelination can be observed in patients with severe poisoning. The abnormalities of the patients are reversible after suitable treatments.

OBJECTIVE:To evaluate the economics of somatostatin,ulinastatin,octreotide and gabexate preventing hyperamy-lasemia and pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP). METHODS:Medical records of 316 cho-ledocholithiasis patients underwent ERCP were selected from our hospital during Jul. 2008-Apr. 2016,and then divided into blank control group(58 cases),somatostatin group(64 cases),ulinastatin group(65 cases),octreotide group(68 cases)and gabexate group (61 cases) according to the use of protease inhibitor. Before ERCP,blank control group received routine treatment as fast-ing,parenteral nutrition support,acid suppression,etc. Based on it,other 4 drug groups received prophylactic drug use according to package inserts 6 h before ERCP. The incidence of hyperamylasemia and pancreatitis after ERCP,VAS scores 3,24,48 h after surgery and the occurrence of ADR were compared among 5 groups. The cost-effectiveness analysis was used to evaluate the eco-nomics of therapy plans in each group. RESULTS:Compared with blank control group,hospitalization time of somatostatin group, ulinastatin group,octreotide group and gabexate group were shortened significantly;the incidence of hyperamylasemia and pancre-atitis were significantly decreased;VAS score 3,24,48 h after surgery were significantly decreased,with statistical significance (P<0.05). Compared among 4 groups,above indexes had no significant difference,and the incidence of ADR was in low level and had no statistical significance(P>0.05). The cost-effectiveness ratio of somatostatin group was the lowest and has cost-effec-tiveness advantage. The results were supported by incremental cost-effectiveness and sensitivity analysis. CONCLUSIONS:Soma-tostatin,ulinastatin,octreotide and gabexate can significantly prevent the occurrence of hyperamylasemia and pancreatitis after ER-CP,and relieve pain with good safety. Somatostatin can achieve the best therapeutic efficacy at the lowest cost,so it is the best plan for hyperamylasemia and pancreatitis after ERCP.

Objective To verify whether miR-498 can inhibit A549 cell migration and invasion by down-regulating FOXM1.Methods miR-498 mimic and miR-NC were transfected into A549 cells.Wound healing and Transwell method were employed to test the migratory ability and invasion ability of A549 cells;Western blot was used to detect the expressions of COL1A1,COL1A5 and FOXM1 in A549 cells.Luciferase assay was used to confirm whether FOXM1 is the target gene of miR-498.Results Compared with those in the control group,the expressions of COL1A1,COL1A5 and FOXM1 were decreased,and the migration and invasion abilities of A549 cells were decreased in the miR-498 group (both P<0 .01 ).The luciferase activity of the FOXM1-3′-UTR plasmid was significantly suppressed by miR-498 (P<0 .05 );over-expression of FOXM1 could reverse the effect of miR-498 on A549 cells.Conclusion miR-498 inhibits A549 cell migration and invasion by down-regulating FOXM1.

Objective To explore the characteristics and method that used modified septoplasty in high posi- tion debiation drawing(or)accompanying dislocation of nosal septum.Methods By performing modified septoplasty on 59 patients who had high position deviation and former dislocation of nosal septum,improvement on method was carried out,and aspects of 59 patients in operation such as data,operation method,follow-up analysis were checked.
