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 investigate the effect of electroacupuncture (EA) on cognitive function in D-galactose (D-gal)-induced aging rats, and the correlation between the effect and nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3)-ASC-Caspase-1 signaling pathway. Methods: Forty-six male Sprague-Dawley (SD) rats were randomly divided into a control group (n=10), a model group (n=12), an EA-7 d group (n=12) and an EA-21 d group (n=12). Except the control group, the other three groups received 42 consecutive days of intraperitoneal injection of D-gal to establish aging rat models with cognitive dysfunction. The control group received the same amount of normal saline via intraperitoneal injection. Two EA groups were given EA therapy for 21 consecutive days (began from the 22nd day of modeling) or 7 consecutive days (began from the 36th day of modeling) accordingly at Dazhui (GV 14), Baihui (GV 20), Shenshu (BL 23) and Zusanli (ST 36). After modeling/ intervention, all four groups received behavioral evaluations by Morris water maze (MWM) test, novel object recognition (NOR) test and step-down passive avoidance (SDPA) test followed by the Western blot (WB) detection of the expression levels of hippocampal NLRP3 inflammasome-associated proteins NLRP3, ASC and Caspase-1. Results: MWM (place navigation test, PNT) results showed that the escape latency in the model group was significantly longer than that in the other three groups (P<0.05), and there was no significant difference among the other three groups on the 1st day of the test (P>0.05). From the 2nd day to the 4th day of the test, there was no significant difference between the EA-21 d group and the control group (P>0.05) in the escape latency; the escape latency was significantly shorter in the EA-21 d group than in the model group and the EA-7 d group (P<0.05). MWM (spatial probe test, SPT) results showed that the time spent in the target quadrant was significantly shorter and platform crossover number was significantly lower in the model group than in the other three groups (P<0.05). The time spent in the target quadrant was longer in the EA-7 d group than in the model group (P<0.05), but was shorter than that in the control group and the EA-21 d group (P<0.05). There was no significant difference in the swimming speed among the four groups (P>0.05). NOR results showed that there was no significant difference in the recognition ratio between the EA-7 d group and the EA-21 d group (P>0.05), and the recognition ratio was significantly higher in the two EA groups than in the model group (P<0.05), but was lower than in the control group (P<0.05). SDPA results showed that the electric shock number was higher in the model group than in the other three groups (P<0.05), and the differences among the other three groups were statistically insignificant (P>0.05). The model group had the shortest step-down latency, followed by the EA-7 d group, the EA-21 d group and the control group in order (P<0.05). The WB results indicated that the expression level of NLRP3 was significantly lower in the control group and the EA-21 d group than in the model group and the EA-7 d group (P<0.05). The expression levels of ASC and Caspase-1 were significantly higher in the model group than in the other three groups (P<0.05), and there was no significant difference among these three groups (P>0.05). Conclusion: NLRP3 inflammasome may be involved in the development of cognitive decline in aging rats; 7 consecutive days of EA intervention can partially improve the cognitive impairment in aging rats though the effect is rather limited; 21 consecutive days of EA intervention may improve the learning and memory abilities in aging rats via downregulating the expression levels of NLRP3 inflammasome-associated proteins in hippocampus.

To prepare ginseng saponin Compound K with ultrasound-assisted total zymolytic ginseng saponins. The conversion rate was taken as the index to detect the pre-treatment factors such as ultrasonic power and ultrasonic time, as well as the impact of enzymatic factors, such as pH value, temperature, concentration of substrate, dosage of enzyme and reaction time, on the conversion rate. The response surface method was used to optimize the preparation conditions. The enzymolytic products were identified with MS, 1H-NMR and 13C-NMR. The results showed that the optimum conditions of the ultrasound-assisted enzymolysis were 250 W for ultrasonic power, 15 min for ultrasonic time, 5.5 for enzymolytic pH, 50 degrees C for enzymolytic temperature, 36 h for enzymolytic time, 4:5 for enzymolytic dosage: substrate and 1.0 g x L(-1) for concentration of substrate. The relative molecular mass of reaction products was 622.4. Therefore, the nuclear magnetic map verified that the reaction product was rare ginseng saponin Compound K. Under the above conditions, based on the total zymolytic ginseng saponins, the conversion rate of rare ginseng saponin Compound K was 6.91% in proportion to the total of ginsenosides. The process features gentle reaction conditions, high conversion rate and simple and reliable process, which is suitable for industrial production.
