Journal of International Pharmaceutical Research 2017;44(5):420-426
Objective To construct the lentivirus plasmids of human Toll like receptor-5(TLR5)and nuclear factor(NF)-κB signaling pathway responsive luciferase and green fluorescent protein(GFP)reporters, and establish a HEK-293 cell line stably expressing human TLR5 and NF-κB responsive reporters. Methods The TLR5 and 5×NF-κB-binding sites genes were cloned to lentiviral expressing plasmid pWSLV-puro and pWSLV-nanluc-GFP, respectively. The recombinant plasmids, pWSLV-hTLR5-puro and pWSLV-5×NF-κB-nanluc-GFP were respectively transfected with packaging plasmid into HEK293T cells in order to package lentivirus. The lentivirus was used to coinfect HEK-293 cells, and the positive clones stably expressing TLR5 and NF-κB responsive reporter (HEK293-N-T)were generated using colony-purification in present of puromycin and fluorescence activated cell sorting. The cells expressing TLR5 were confirmed by Western blot and immunofluorescence. Additionally, the cells expressing NF-κB responsive reporter were confirmed by fluorescence microscopy and luciferase quantitative assay. Results The results of recombinant plasmids digestion identification and the sequencing of cDNA showed that the sequences inserted into the plasmid and the expected sequences of hTLR5 and 5×NF-κB-binding sites genes were completely consistent. It was confirmed that the hTLR5 and 5×NF-κB-binding sites genes were correctly inserted into the vectors, and that the recombinant plasmids, pWSLV-hTLR5-puro and pWSLV-5×NF-κB-nanluc-GFP, were successfully constructed. Additionally, Western blot and immunofluorescence analysis showed that TLR5 were stably expressed in a high level in the HEK293-N-T cells and located in the cell membranes. Moreover, the results of fluorescence microscopy and luciferase quantitative assay indicated that the NF-κB responsive reporter could reflect the activation of NF-κB signaling in a dose-dependent manner. Conclusion The HEK-293 cell line stably expressing human TLR5 and NF-κB responsive reporter has been successfully established and the HEK293-N-T cells can be used for the screening and evaluation of drugs target to TLR5.

China Journal of Chinese Materia Medica 2018;43(22):4365-4369
Chinese medicine is the treasure of China. It has been the safe guard of health in China for thousands of years. Processing of traditional Chinese medicine (TCM) is an important process of removing crude extracts from natural products and achieving pharmacological properties of TCM. The connotation and norms of herbal preparation in the past dynasties have been improved gradually, and have been included in the code system since the Tang Dynasty. The process of legislative evolution is closely related to the fate and development of TCM. In the era of full-scale rejuvenation of Chinese medicine, with the development of Chinese medicine industry to 4.0, the perfection of the standards and standard system with the construction of quality standardization of Chinese medicine as the core, especially under the Pharmacopoeia system, is the important support and guarantee for the promotion of the whole industry, which is also an important part of the rejuvenation of the entire Chinese medicine industry.

Journal of Forensic Medicine 2017;33(1):32-35
OBJECTIVES:
To explore the characteristics of schizophrenia patients' homicide behaviors and the influences of the assessments of criminal capacity.
METHODS:
Indicators such as demographic and clinical data, characteristics of criminal behaviors and criminal capacity from the suspects whom were diagnosed by forensic psychiatry as schizophrenia (n=110) and normal mental (n=70) with homicide behavior, were collected by self-made investigation form and compared. The influences of the assessments of criminal capacity on the suspects diagnosed as schizophrenia were also analyzed using logistic regression analysis.
RESULTS:
There were no significant statistical differences between the schizophrenic group and the normal mental group concerning age, gender, education and marital status (P>0.05). There were significant statistical differences between the two groups concerning thought disorder, emotion state and social function before crime (P<0.05) and there were significant statistical differences in some characteristics of the case such as aggressive history (P<0.05), cue, trigger, plan, criminal incentives, object of crime, circumstance cognition and self-protection (P<0.05). Multivariate logistic regression analysis suggested that thought disorder, emotion state, social function, criminal incentives, plan and self-protection before crime of the schizophrenic group were positively correlated with the criminal capacity (P<0.05).
CONCLUSIONS
The relevant influences of psychopathology and crime characteristics should be considered comprehensively for improving the accuracy of the criminal capacity evaluation on the suspects diagnosed as schizophrenia with homicide behavior.
