Objective T o understand the assessm ent on the criminal responsibility of drug-induced m ental disorders and judicial experts’ opinions. Methods T he judicial experts from institutes of forensic psychi-atry in Shanghai were selected. T hey were asked to finish a self-m ade questionnaire of assessm ent on the criminal responsibility of drug-induced m ental disorders by letters and visits. Results Most of experts knewthe special regulation,“not suitable for evaluation” towards the criminal responsibility of drug-in-duced m ental disorders of the guideline prom ulgated by Ministry of Justice. B efore and after the guide-line was issued, no expert m ade a no-responsibility opinion in such cases. After the guideline was issued, som e experts m ade a full-responsibility or lim ited-responsibility opinion in such cases. T here was a little disagreem ent am ong the experts in the case that the crime was unrelated with m ental sym ptom s or the criminals used drugs even though he knewit could induced insanity. B ut there were still m any obvious disagreem ents am ong experts in the case that crime was related to such sym ptom s and person was no ability to debate. Most experts agreed to settle the disagreem ents with im proved legislative perfection. Conclusion Most experts are not strictly com plying with the assessm ent guidelines during their practice, and there is still an obvious disagreem ent towards the criminal responsibility of drug-induced m ental disorders.

BACKGROUND: Many experiments have proved that heavy-load movement training causes the acute increase of free radicals. The increase of endogenous free radicals and caused cellular and subcellular lipid peroxidation strengthening injure the structure and function of tissue cells, thereby, decrease motor ability. Sleep deprivation also causes the increase of oxygen free radicals.OBJECTIVE: To observe the changes in malondialdehyde (MDA) and glutathione (GSH) levels as well as superoxide dismutase (SOD) activity in serum of acute exhaustive exercise rats following different time periods of sleep deprivation.DESIGN: A randomized controlled animal experiment.SETTING: Laboratory of Exercise Sciences & Sports Medicine, Physical College, Hunan Normal University.MATERIALS: Thirty healthy male SD rats of clean grade, weighing about (220±13)g, provided by Experimental Animal Center of Hunan Agricultural University, were involved in this study.METHODS: This experiment was carried out in the Laboratory of Exercise Sciences & Sports Medicine, Physical College,Hunan Normal University from April 2006 to May 2006. Thirty rats were randomized into 5 groups: blank control group,simple exercise group, sleep deprivation 24 hours group, sleep deprivation 48 hours group and sleep deprivation 72 hours group, with 6 rats in each group; Rats in the blank control group were allowed to sleep normally, but not do exercise; Rats in the simple exercise group were allowed to sleep normally and executed after acute exhaustive exercise; Rats in the sleep deprivation 24, 48 and 72 hours groups were deprived their sleep for 24, 48 and 72 hours,respectively, then they were executed after acute exhaustive exercise. Method of gentle handling was used in creating rat models of sleep deprivation; Rats in the simple exercise group and sleep deprivation groups were forced to do exercise according to the rat exercise model project established by Bedford: treadmill gradient 10°, speed 19.3 m/min, all the exercise rats were exhaustive (Exhaustion criteria: At the end of exercise, rats reached 1/3 of runway over 3 times;Various stimulations for expelling were invalid. After running, rats presented with breathlessness, expression lassitude,ventral decubitus, slow stimulus response, weaker escape response in being captured). After experiment, rats in each group were executed under the anesthetic state, and their blood was taken out, and centrifuged after natural clotting.Supernatant fluid was taken for detecting MDA and GSH levels as well as SOD activity.MAIN OUTCOME MEASURES: Changes in MDA and GSH levels, and SOD activity in rat serum.RESULTS: Thirty rats were involved in the final analysis. ① MDA level in the simple exercise group was higher than that in the blank control group (P＜ 0.01). MDA level in the sleep deprivation 24 hours, 48 hours and 72 hours was higher than that in the simple exercise group, respectively (P ＜ 0.01). MDA level in the sleep deprivation 72 hours was statistically higher than that in the other sleep deprivation groups, respectively (P ＜ 0.01). ②GSH level in the simple exercise group was lower than that in the blank control group (P ＜ 0.01). GSH level in the sleep deprivation 24 hours group was higher than that in the simple exercise group [(P ＜ 0.01). GSH level in the sleep deprivation 24 hours and 48 hours groups was lower than that in the simple exercise group, respectively (P ＜ 0.05, 0.01). There were statistical differences in GSH level among sleep deprivation groups (all P＜ 0.01). ③ SOD activity in the simple exercise group was lower than that in the blank control group (P ＜ 0.01); SOD activity in the sleep deprivation 24, 48 and 72 hours groups was lower than that in the simple exercise group, respectively (P ＜ 0.01); SOD activity in the sleep deprivation 48 and 72 hours groups was significantly lower than that in the blank control group, respectively (P ＜ 0.01); There were statistical differences in SOD activity among sleep deprivation groups (P ＜ 0.01).CONCLUSION: Sleep deprivation can cause serumal oxidative stress injury of rats; With elongation of time of sleep deprivation and exhaustive exercise, oxygen free radical production in serum of rats accumulates more and more, ability to get rid of oxygen free radical becomes weaker and weaker, and injury to body is more and more obvious.Serumal oxidative stress status of acute exhaustive exercise rats following sleep deprivation

Objective This study was to evaluate the safety of 640 corneal donors by analysing the serological testing results.Methods We retrospectively analyzed the serological testing results from Changsha Aier Eye Bank and Chengdu Kangqiao Aier Eye Bank from January 2011 to December 2015,hepatitis B virus surface antigen (HBsAg),hepatitis C virus (HCV),treponema pallidum (TP) and human immunodeficiency virus (HIV) were detected by colloidal gold or enzyme-linked immunosorbent assay (ELISA).Results There were 83 out of 640 serum samples showed positive immuno-reaction assayed markers,the positive rate was 12.97％,including HBsAg(n=60,9.38％),HCV(n=3,0.47％),TP(n=11,1.72％) and HIV(n=2,0.31％).Moreover,3 corneal donors were both positive against HBsAg and HCV,2 donors positive against HCV and TP,1 donor positive against HBsAg and HIV,1 donor positive against HBsAg and TP.Conclusions There is a high proportion of positive results of blood-borne diseases in cornea donors,which is a potential threat to corneal receptors and eye bank workers.Therefore,it is very important to detect serological test strictly for corneal donors.

Objective To evaluate the effect of nutritional risk screening and interventions on postoperative nutritional status in patients with oral cancer. Methods A total of 83 oral cancer patients with mild or moderate nutritional risk rated by patient-generated subjective global assessment(PG-SGA) from January 2015 to June 2017 were randomized into an experimental group(43 cases) and a control group (40 cases). The patients in the experimental group received 2-week nutritional intervention before the operation,while the patients in the control group received routine preoperative treatment and diet guidance. The biochemical measurements of postoperative nutritional indicators, peripheral blood immunoglobulin indicators, postoperative complications and hospital stays were compared between the two groups. Results The levels of prealbumin, retinol- binding protein, total lymphocyte count and transferrin were (218.5±34.6) mg/L, (23.5±4.3)μg/L, (1.82±0.45)×109/L, (2.07±0.63 )μg/L on the day of admission in the experimental group, and at 1 day before the operation were (237.3±36.5) mg/L, (27.7±4.8)μg/L, (2.02±0.39)×109/L, (2.43±0.54)μg/L, there was no significant difference(P<0.05). IgM, IgG, IgA at 1 day before the operation were significantly higher than those on the day of admission in the experimental group(P<0.05), and the levels of prealbumin, retinol-binding protein, total lymphocyte count,transferrin, IgM, IgG, IgA and body mass index at 8 days after the operation in the experimental group were significantly higher than those in the control group(t=1.574-3.418, P<0.05). The total rate of postoperative complications was 11.6％(5/43) in the experimental group, 30.0％(12/40) in the control group, and there was significant difference between the two groups (χ2=6.840, P<0.01). The incidence of infection-associated complications such as pneumonia and incision infection was 7.0％(3/43) in the experimental group, 20.0％(8/40) in the control group, and there was significant difference between the two groups (χ2=5.096, P<0.05). Conclusions Preoperative nutritional support can effectively improve the perioperative nutritional status,decrease postoperative complications and operative risk in esophageal cancer patients with mild or moderate nutritional risk.
