AIM: To study the effect of shenmai injection (SMI), a Chinese medicine, on nitric oxide and the expression of endothelial nitric oxide synthase (eNOS) mRNA in myocardium of rats with experimental myocardial ischemia. METHODS: Rats were randomly divided into four groups: control, model (ischemia), SMI 1 and SMI 2 group. A rat model of acute myocardial ischemia was established by isoprenaline treatment and the lift of ST segment in ECG was used as the index of myocardial ischemia. The nitric oxide (NO) contents in serum and myocardium and the expression of eNOS mRNA in myocardium were measured. RESULTS: Compared with control group, ST segment of ECG was significantly elevated 20, 30, 40 min after myocardial ischemia in model group, the lift peak of ST segment occurred 20 min after myocardial ischemia, the concentration of NO in the serum and myocardium and the expression of eNOS mRNA in myocardium were significantly lowered in model group. Compared with the model group, in SMI 1 group and SMI 2 group, the concentration of NO in the serum and myocardium and the expression of eNOS mRNA in myocardium were significantly increased, the lift of ST segment were significantly reduced 20, 30, 40 min after myocardial ischemia. Compared with SMI 1 group, the concentration of NO in the serum and myocardium and the expression of eNOS mRNA in myocardium and the lift of ST segment were not statistically different in SMI 2 group. CONCLUSION: Shenmai injection can increase the expression of eNOS mRNA in myocardium and the content of NO, and protect against myocardial ischemia in rats.

Objective To understand the epidemic characteristics of imported malaria in Henan Province from 2012 to 2014,so as to provide the evidence for proposing the reasonable suggestions for imported malaria prevention and control. Meth?ods The data of imported malaria were collected and the epidemic characteristics were analyzed in Henan Province from 2012 to 2014. Results A total of 569 imported malaria cases were reported in Henan Province from 2012 to 2014,including 445 cas?es of falciparum malaria,48 cases of vivax malaria,61 cases of ovale malaria,14 cases of quartan malaria,and 1 case of mixed infection. All the malaria cases were confirmed in laboratory. During the three years,the time of higher incidence was in Spring Festival,and May and June,and the cases mainly distributed in Luoyang,Zhengzhou,Puyang,Xinxiang,Anyang,Xuchang and Nanyang cities,accounting for 68.54%. Totally 82.43%of the patients were male youth and middle?aged. Of the 569 pa?tients,534(93.85%)returned from Africa and 35(6.15%)returned from Southeast Asian countries. The average time was 6.22 d and the median was 4 d from the onset to diagnosis. Among 569 cases,290(50.97%)were confirmed by different levels of cen?ters for disease prevention and control,and 279(49.03%)were diagnosed by different levels of medical institutions. Conclu?sions The imported malaria cases have been increased obviously in recent 3 years in Henan Province. Therefore,the health ed?ucation for the knowledge about malaria prevention and control,and the technician training should be strengthened.

Objective To retrospectively overview the malaria death cases reported in Henan Province and analyze the cause of death. Methods The data including basic information,epidemiological survey and medical records of malaria death cases in Henan Province from 2010 to 2015 were collected and analyzed. Results In the six years,a total of 14 malaria pa?tients were dead. All the death patients were adult males and imported from Africa. They had definite histories of living in malaria?epidemic areas and the symptoms of fever. Twelve patients were diagnosed as malaria after at least twice diagnoses. The average time from symptom appearing to correct diagnosis was 6.5 d. The causes of deaths were misdiagnosis and delayed treatment. Con?clusions The major reasons of malaria death cases in Henan Province are the failure of correct diagnosis and prompt treatment. Health education of malaria prevention and diagnosis and treatment training of malaria should be strengthened in order to im?prove the public awareness and the diagnosis ability of clinical doctors for malaria,which can prevent the death of imported ma?laria cases.

OBJECTIVETo assess the relationship between histological type and fluorine-18 fluorodeoxyglucose(FDG) uptake in patients with primary lung cancer and the factors affecting FDG uptake.
METHODSFrom October 1998 to April 2001, 82 patients with lung cancer were imaged with FDG-PET (Positron emission tomography) before surgery or biopsy. Their maximum and mean standard uptake value(SUVmax and SUVmean) of tumor and SUV of normal lung (SUVlung) were measured.
RESULTSAll tumors were detected by FDG-PET(r)FDG uptake of tumor was higher than that of normal lung (P < 0.01). FDG uptake was lower in adenocarcinoma(AC) than in squamous cell carcinoma (SQC), and that of bronchial aveolar carcinomas(BAC) was the lowest [SUVmax was 8.42 +/- 4.05,5.91 +/- 3.91 and 2.97 +/- 1.10, respectively; SUVmean was 6.12 +/- 2.90,4.35+/- 3.10 and 2.25 +/- 0.99, respectively (P < 0.01)]. Correlations were found between FDG uptake and tumor size (P < 0.01)(r)Glucose level and SUV of normal lung could affect SUV of lung cancer (P < 0.05).
CONCLUSIONSSUV is higher in cancer tissue than in normal lung tissue. FDG uptake is different among SQC,AC and BAC. FDG uptake and tumor size appear to be correlated with each other.SQC, AC and BAC have their own features respectively. The effects of glucose and SUV lung should be considered in the diagnosis of lung cancer with PET.
