Objective To analyze the epidemic characteristics of mushroom poisoning incident in order to find the regularity of outbreak and provide the fundamental guidelines of prophylaxis,control,diagnosis and treatment.Methods According to the reported information from the Management Information System of Public Health Emergency in China mainland,the area-time distribution of mushroom poisoning incidents from 2004 to 2014 was analyzed,and the descriptive analysis of mushrooms poisoning incidents including causes,places,occupation of victims and incidents identification were made from 2010 to 2014.Results In China (excluding Hong Kong,Macao and Taiwan),the top five provinces of mushroom poisoning incidents were Yunnan,Guizhou,Sichuan,Guangxi and Hunan.The epidemic peak was reached in summer-autumn season.The major and significant incidents accounted for 76.56％ of overall mushroom poisoning incidents,and the fatality rate of 3 701 patients accounted for 21.24％ (786 deaths).The causes were mistaking poisonous mushrooms as edible mushrooms or purchasing poisonous mushrooms in the market by accident.About 87.50％ incidents happened at home.Farmers,workers,children and students were easily subjected to mushroom poisoning because of their large range of activities,strong curiosity and lacking related ability for distinguishing edible mushroom from poisonous mushrooms.No identification was done in 200 mushroom poisoning incidents from 2010 to 2014,which accounted for 92.59％ of mushroom poisoning incidents in the corresponding period.Standard species identification was carried out only in two poisonous mushroom incidents.Conclusions Mushroom poisoning incident was one of the most important causes of death in per-oral poisoning incidents.It should to cope with surveillance and meticulous management during high prevalence season and in high-risk provinces.At the same time,it should be strengthened to train doctors and health professionals with the knowledge of identification of mushroom poisoning in key areas as well as to develop the health promotion of mushrooms poisoning prevention.

Objective To discuss the value of hypotonic-MRCP combined with LAVA dynamic contrast-enhanced scan in diagnosis of duodenal tumor.Methods Five patients with duodenal adenocarcinomas confirmed by pathology were involved in this study.All cases underwent plain MRI and hypotonic-MRCP and LAVA dynamic contrast-enhanced scans.Results 4 of 5 cases were correctly diagnosed with MR imaging.Imaging signs included:the cavum of descending duodenum appeared as asymmetrical stenosis,masses with soft tissue signal intensity connecting the intestinal wall with wide base,the intestinal wall stiff,the intestinal mucosa destruction.The lesions would be slightly-moderately enhanced at LAVA dynamic enhancement scanning.Conclusion Hypotonic-MRCP combined with LAVA dynamic contrast-enhanced scan can display the direct and indirect sign of duodenal tumors,which was effective in identifying the circumscription of the tumor and its extension.

Objective To compare the effects of ephedrine and phenylephrine on hemodynamics in the patients undergoing surgery in prone position under general anesthesia.Methods Sixty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients, aged 20-60 yr, with body mass index of 18.5-2:5.0 kg/m2, scheduled for elective posterior lumbar interbody fusion under general anesthesia, were randomized to ephedrine group (group E, n =30) or phenylephrine group (group P, n =30).When hypotension [decrease in systolic blood pressure (SBP) ＞20％ of the baseline value, T0] occurred in supine position, SBP, diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR), cardiac output (CO), cardiac index (CI) and central venous pressure (CVP) were recorded, and ephedrine 0.1 mg/kg (group E) or phenylephrine 1 μg/kg (group P) was injected via the central veins.The parameters mentioned above were recorded within 10 min after administration (T1-T10).Results Both ephedrine and phenylephrine could maintain the parameters of hemodynamics at the normal level.Compared with the baseline values at T0 , SBP, DBP, MAP and HR at T1-T10 and CO and CI at T2-T10 were significantly increased, and no significant change was found in CVP at each time point after administration in group E, and SBP and MAP at T1-T6, DBP at T1-T5, CVP at T2 and T3, and CO and CI at T1-T3 were significantly increased, and HR was decreased at T2 and T3 in group P.Compared with group P, SBP was significantly decreased at T1, and increased at T2-T10, DBP and MAP were decreased at T1, and increased at T3-T10, HR was increased at T1-T10, CO and CI were increased at T2-T10, and CVP was decreased at T1-T3 in group E.Conclusion Compared with phenylephrine, although ephedrine provides no significant effect on hemodynamics clinically, it can increase cardiac output to some extent in the patients undergoing surgery in prone position under general anesthesia.

Objective To study the effects of propofol used alone and in combined with opioids in gastroscopy,in order to select the more suitable anesthesia protocol.Methods A total of 285 pa-tients undergoing gastroscopy were selected in April ,201 5 in our hospital,including 105 males,180 females,ranging from 18 to 65 years old,weighing 40-90 kg,falling the category of ASA Ⅰ or Ⅱ. According to random number table,subjects were divided into four groups:dezocine group(group D, n =76),fentanyl group (group F,n =87),oxycodone group (group O,n = 71 )and control group (group C,n =5 1).Each group was implemented the corresponding anesthesia.SBP,DBP,HR,SpO 2 in baseline(T0 ),1(T1 ),3(T2 ),5(T3 )min after entering gastroscope were recorded.Choking cough, body movement,extra propofol,awakening time and inspecting time were observed.Results Among four groups,there was no statistical significance in age,gender,weight,blood pressure,heart rate and oxygen saturation and other general information.There were more cases given extra propofol in group C than in the other three groups (P <0.01 ).While for the experimental groups,there were more cases needing extra propofol in group O than in group D and group F (P < 0.01 ).The incidences of body movement and choking cough in group C were higher than those in the other three groups (P <0.01 ).Compared with the group C,dosage of propofol ,awakening time in the three groups,especially in group D,were much lower (P < 0.01 ).Conclusion Propofol in combination with opioids for sedation during painless gastroscopy can alleviate adverse reaction caused by propofol used alone.The more suitable anesthesia protocol is propofol with dezocine.

Abstract Research has shown that occupational stress is closely related to the occurrence and progression of atherosclerosis, with immune dysregulation serving as a mediating factor. Occupational stress triggers immune dysregulation in the body, ultimately leading to atherosclerosis through mechanisms such as the activation of immune cells and inflammatory mediators, endothelial dysfunction, and lipid metabolism disorders. This article reviews the primary mechanisms by which immune dysregulation plays a role in atherosclerosis caused by occupational stress, providing the reference for the prevention and intervention of atherosclerosis.

Objective To evaluate the effect of haploidentical lymphocyte infusion on refractory and relapse acute leukemia. Methods The haploidentical donor lymphocyte infusion was used to treat for relapse acute myeloid leukemia 3 patients (M2 2 eases, M4 lcase), one relapse acute lymphocyte leukemia from April 2006 to October 2007. Four cases who had accepted secondly regimens were ineffective,after relapse. Collecting donor lymphocytes, parents children as donor supply in 3 cases, mother as donor supply one case. Before donor lymphocyte infusion patients received chemotherapy of different regimens. Donor haploidentical iymphocytes irradiated by 6-8 Gy radial were infused when patients white cell count was at the lowest after the chemotherapy. The average of infusion cells was 2.3 (1.4-3.1)×108/kg. Results One patient acquired complete remission and two patients were effective in three relapse acute myeloid leukemia. It was ineffective in relapse acute lymphocyte leukemia. No transfusion related graft versus host disease was observed. One patient has had herpes zoster virus infection. Conclusion Haploidentical donor lymphocyte infusion with chemotherapy are effective for refractory and relapse in acute myeloid leukemia, but the infused cell quantity and irradiated dosage must be further discussed.
