72 cases of treatments on insomnia were recorded in the medical books of Ming and Qing dynasties(A.D.1368～1911 years).The compatibility regularity of treating insomnia in these 72 cases were statistically analyzed with frequency and the R type cluster analysis methods. Combining the data and modern recognition, compatibility and medication regularity of treating insomnia was further analyzed.

Objective Through the research of the disposal of clinic laboratory result information,the paper explore the methods of building up laboratory's online management system and network information system.Methods This project began with the analysis of the need of laboratory and applies computer to simulate the manual disposal process.The system framework was separated into many sub parts according to its function.VB,etc were used to program.Results The project has been gained successfully in the online managemert of two analyzers and the management of data network consisting of three laboratories.Conclusion The project has established a practical and reliable in-formation management system which matches the work mode in clinical laboratory and has novelty functions.

Objective To investigate the role and action mechanism of rosemarinic acid(RA)on the malignant behavior of colorectal cancer(CRC)SW480 cells.Methods We collected tumor tissues from patients with primary untreated CRC who underwent surgery in People's Hospital of Rugao from January 2019 to December 2020,as well as colon tissues from normal individuals.The expression of β-catenin was detected by immunohistochemistry and Western blotting to analyze its relationship with the clinical stage,prognosis,and immune infiltration.CCK-8 was used to detect the effects of 10,15 and 20 μmol/L of RA on the proliferation of SW480 cells;flow cytometry detected apoptosis;Transwell and scratch assay detected changes in the invasion and migration ability of the cells,respectively.Western blotting detected the expressions of proteins related to apoptosis,epithelial-mesenchymal transition(EMT),and Wnt/β-catenin pathway.A mouse model of CRC transplant tumor was established,and the effect of RA on the growth of transplant tumor was investigated by gavage administration.The levels of inflammatory factors were detected by ELISA.Results The expression of β-catenin was low in normal colon tissues and significantly higher in CRC tissues.In the CRC patients with high expression of β-catenin,the number of patients with tumors larger than 5 cm was significantly higher than that in the low expression group,whereas the overall survival of the patients was significantly smaller than that in the low expression group(P＜0.05).Cell proliferation was significantly inhibited and decreased in a concentration-dependent manner in the RA group at all concentrations(P＜0.05).In animal experiments,the expression of apoptotic proteins Bax and Bad was significantly increased and the expression of anti-apoptotic protein Bcl-2 was significantly decreased in the RA-treated group compared with the control group(P＜0.05).It was also found that the invasive and migratory ability of SW480 cells was significantly inhibited(P＜0.05),the expression of E-cadherin protein was significantly increased,the expression of Snail,N-cadherin and Vimentin was significantly reduced(P＜0.05),the expression of Axin and GSK-3β was increased,and the expression of β-catenin was reduced(P＜0.05).Conclusion RA may inhibit the biological activity of SW480 by interfering with Wnt/β-catenin pathway-mediated EMT.

[Objective] To investigate the inhibitory effect of quercetin on cisplatin-resistant human colorectal cancer (CRC) cells SW480 and SW620 and its possible mechanism. [Methods] Cisplatin-resistant subtypes of SW480 and SW620 cells were first cultured and the effects of quercetin on cell proliferation and chemosensitivity were determined by MTT assay. Flow cytometry was used to detect apoptosis and protein blotting was used to detect the expressions of relevant proteins. [Results] MTT assay showed that quercetin at the concentrations of 80 μmol/L and 160 μmol/L significantly inhibited the proliferation of SW480 and SW620 cells. Flow cytometry results showed that the apoptosis rate was significantly higher in the cisplatin combined with quercetin group than in the other three groups. Protein blotting showed that cleaved-caspase-3 and caspase-9 expressions were significantly increased in the cisplatin combined with quercetin group. The chemotherapeutic drug sensitivity assay showed that the elevated IC50 of drug-resistant cells was decreased significantly after quercetin administration (P<0.05). [Conclusion] The present study clarifies that quercetin can increase the sensitivity of human CRC cells to cisplatin. This effect may be related to its mechanism of action in affecting cell proliferation, apoptosis and autophagy.

Ribosome-inactivating proteins (RIPs) belong to a family of enzymes that attack eukaryotic ribosomes and potently inhibit cellular protein synthesis. RIPs possess several biomedical properties, including anti-viral and anti-tumor activities. Multiple RIPs are known to inhibit tumor cell proliferation through inducing apoptosis in a variety of cancers, such as breast cancer, leukemia/lymphoma, and hepatoma. This review focuses on the anti-tumor activities of RIPs and their apoptotic effects through three closely related pathways: mitochondrial, death receptor, and endoplasmic reticulum pathways.
