OBJECTIVE: To understand the assessment on the criminal responsibility of drug-induced mental disorders and judicial experts' opinions. METHODS: The judicial experts from institutes of forensic psychiatry in Shanghai were selected. They were asked to finish a self-made questionnaire of assessment on the criminal responsibility of drug-induced mental disorders by letters and visits. RESULTS: Most of experts knew the special regulation, "not suitable for evaluation" towards the criminal responsibility of drug-induced mental disorders of the guideline promulgated by Ministry of Justice. Before and after the guideline was issued, no expert made a no-responsibility opinion in such cases. After the guideline was issued, some experts made a full-responsibility or limited-responsibility opinion in such cases. There was a little disagreement among the experts in the case that the crime was unrelated with mental symptoms or the criminals used drugs even though he knew it could induced insanity. But there were still many obvious disagreements among experts in the case that crime was related to such symptoms and person was no ability to debate. Most experts agreed to settle the disagreements with improved legislative perfection. CONCLUSION Most experts are not strictly complying with the assessment guidelines during their practice, and there is still an obvious disagreement towards the criminal responsibility of drug-induced mental disorders.

Objective To explore the feasibility of extending liver blood perfusion cessation by ultrasound combining microbubbles.Methods The livers of 9 healthy rabbits were treated with a pulsed therapeutic ultrasound device,in presence of microbubbles.For quantification of liver perfusion,contrastenhanced ultrasonography was performed on 6 rabbits before treatment and at different time points of 0 min,30 min,60 min and 48 hours after treatment.Pathological examination of the treated livers was performed immediately after treatment on the other 3 rabbits.Results The liver blood perfusion almost vanished immediately after treatment,remained at a low perfusion level from 30 to 60 min,and completely recovered 48 hours later.The peak intensity dropped from ( - 51.88 ± 4.26)dB to ( - 62.53 ± 4.83)dB after treatment and rose up to ( - 52.00 ± 4.60) dB 48 hours later.The peak intensities before treatment and 48 hours after treatment were significantly higher than those of 0 min,30 min and 60 min time points after treatment( P ＜0.05).Pathological examination showed significant swelling of hepatocytes and hemorrhage around portal veins.Conclusions Microbubbles enhanced ultrasound can induce liver blood perfusion cessation for up to 1 hours.The mechanism could be swelling of hepatocytes and hemorrhage of portal track.

Objectives To evaluate the clinical value of neoadjuvant chemotherapy (NACT) in the treatment of local advanced cervical cancer. Methods We searched the clinical trials on the treatment of local advanced cervical cancer with NACT followed by surgery versus initial surgery on English and Chinese published literatures from the main medical data resources (MEDLINE, PUBMED, ELSEVIER ScienceDirect, CNKI). The data about positive pelvic nodes, interstitial infiltration, vascular invasion, positive surgical margin, 3-year overall survival (OS), 3-year disease-free survival (DFS), 5-year OS, 5-year DFS were extracted from these papers, and a meta-analysis was applied. Result The hazard ratio (HR) of positive pelvic nodes on NACT group versus control group was 0. 54(95% CI 0. 33 ～0. 86), HR of interstitial infiltration was 0. 45(95% CI 0. 24 ～0. 86), HR of vascular invasion was 0. 25(95% CI 0. 16 ～0. 38), all differences were statistically significant. And HR of positive surgical margin was 0. 45 ( 95% CI 0. 21 ～0. 99), P = 0. 05, which indicated the difference was not statistically significant. And there were also no significant difference on the HR of 3-year OS, 3-year DFS, 5-year OS and 5-year DFS, and their RR were 1.18(95% CI 0. 84 ～ 1.66) ,1.31 (95% CI 0. 96 ～ 1.78) ,0. 89(95% CI 0. 68 ～ 1.15) ,and 0. 99(95% CI 0. 71 ～ 1.93) respectively. Conclusion For local advanced cervical cancer, NACT could reduce pathological risk factors but it did not improve the survival.

Background With the changes of diet and living style,the diabetes has become the major diseases affecting human health.Diabetic cataract is a common complication of diabetes. Objective The present study was to investigate the difference of lens proteomics between diabetic cataract and age related cataract using two dimensional electrophoresis (2-DE) and mass spectrometry in order to postpone happening of diabetic cataract and offer the effective approach to the prevention and therapy of diabetic cataract. Methods The lenses were obtained from 8 diabetic patients and 12 age-related cataract patients during the surgery to extract the protein by lysis and centrifugation.The lens proteins were separated using immobilized pH gradients 2-DE.Image analysis was carried out using PDQuest Advanced-8.0.1 software package.Significant difference of the crystallines was identified by matrixassisted laser adsorption/ionization time of-flight-mass spectrometry (MALDI-TOF-MS) and peptide mass fingerprint combined with protein database. Results The maps of 2-DE showed that lens proteins of diabetic cataract and age related cataract were in the section of pH 5-9 with the relative molecular weight 14000-97000;while relative molecular weight of more abundant crystalline was localized at 20000-31000.About 3 differential protein spots were detected by image analysis software.Two crystallines,αB and βB1 crystallin,were identified using MALDI-TOF-MS.Conclusions Proteomic analysis of lens can be accomplished and the proteins can be well separated,moreover,differential proteins can be analyzed using 2-DE and mass spectrometry between diabetic cataract and age related cataract.These results indicate that αB and βB1 crystallin proteins accelerate the development of diabetic cataract.This technique offers a new avenue for clarity of lens proteins of diabetic cataract other than age related cataract.
