AIM:To establish the method for quality control of Huisheng Diyidan Tablet(Eupolyphagea seu Steleophaga;Radix Angelicae sinensis,Sanguis Draconis,etc.). METHODS: Radix Angelicae sinesis,Eupolyphaga seu Steleophaga,Chinnabaris,Moschus,Boswellia carterii were identified by microscope.Sanguis Draconis was identified by TLC,Pyritum was identified by general identified reaction;The content limitation of cinnabaris(HgS) was determined by titration.Ferulic acid content of Radix Angelicae sinensis was determined by HPLC. RESULTS: Every part of the tablet was identified,the content limitation of cinnabaris(HgS) and ferulic acid content of Radix Angelicae sinensis were determined. CONCLUSION: The method showed that the characteristic for identification is distinct and highly specific,quantitative assay is simple,accurate,reliable and can be used for quality control of Huisheng Diyidan Tablet effectively.

As an important immune organ,the liver has a unique immune microenvironment,and is one of the important places for innate immunity and adaptive immunity.The liver is closely connected with the immune system through the gut-liver axis and is also the target or-gan of immune injury.However,the defensive role of the liver for Hepadnaviridae remains unclear.Cell therapy for liver diseases includes input of liver cells or stem cells for functional replacement,therapy by immune cells for antiviral and antitumor purposes,and genetic therapy for hereditary hepatopathy with cells as the carrier.The features of mesenchymal stem cells,multi-directional differentiation potential and immunomodulatory property,become the hot spots of cell therapy for liver diseases,and efficient in vitro amplification of cells makes it possi-ble for the use of NK cells in the treatment of hepatocellular carcinoma.

AIM:To research the chemical modification from berberine hydrochloride to berberrubine in Cortex Phellodendri before and after processing.METHODS:Berberrubine was isolated by column chromatography and the contents of berberine hydrochloride and berberrubine in different processed Cortex Phellodendri were determined by HPLC.RESULTS:With increacing processing temperature and time,part of berberine hydrochloride became berberrubine in processed Cortex Phellodendrin,and berberrubine content decreased under the condition of high temperature operation or overtime processing.CONCLUSION:The experimental data shows that the processed Cortex phellodendri has the maximum average content of berberrubine as processing temperature is maintained as 180℃ for 40 min.

Objective:To study the antibacterial properties of pure titanium treated with benzalkonium chloride solution.Meth-ods:10 mm ×10 mm ×1 mm titanium specimens were processed by the benzalkonium chloride solution at 1%,0.5% and 0.1%respectively followed by treatment in the cultured bacterial suspension,and then the antibacterial properties of the titanium plates were examined.Additionally,the thermal cycling test was carried out for the 1% benzalkonium chloride-treated titanium plates, and subsequently put the plates into cultured bacterial suspension,the duration of antibacterial properties was observed.Results:0.5% and 1% benzalkonium chloride solution-treated titanium plates significantly inhibited the growth of candida albicans(P <0. 05),1% solution was more effective than 0.5% solution.After 1 000 and 2 500 thermal cycling,the pure titanium still retained the antibacterial ability,but the plates treated by 5 000 cycling showed no antibacterial effect.Conclusion:A certain concentration of benzalkonium chloride can make the pure titanium obtain antibacterial properties.The treated plates may maintain the antibacte-rial properties for a minimum of 3 months.

Homeostasis between the host and viruses is naturally maintained.On the one hand,the immune system activates the immune re-sponse to kill or eliminate viruses;on the other hand,the immune system controls the immune response to maintain immune homeostasis. The cause of persistent infections with hepatitis viruses such as HBV and HCV is that viral molecules damage the immune system of the host and their variants escape immune clearance.Long-term coexistence of the host and viruses is the process involving various immune cells and molecules and is the result of homeostasis maintenance in antiviral immune response.The immune homeostasis maintained during persis-tent infections with hepatitis viruses is analyzed by the cellular and molecular mechanisms.

OBJECTIVE:To provide a reference for innovative drugs to enter the health insurance directory smoothly and pro-mote the rapid development of pharmaceutical industry in China. METHODS:Based on related policy study of foreign and domes-tic innovative drugs entering the health insurance directory,the policy barriers of innovative drugs entering the health insurance di-rectory were analyzed and the countermeasures were put forward. RESULTS & CONCLUSIONS:In China,the foundation of drug selection was not objective enough;the review results were so vulnerable to subjective views because of the experts selection mech-anism;the health insurance directory deletion mechanism was deficient;the waiting time for innovative drugs entering the health in-surance directory was too long;innovative drugs negotiation mechanism was imperfect,etc. It is recommended that forcibly requir-ing pharmaceutical companies should provid the related data about pharmacoeconomic evaluation;the independence and pluralism of the expert group should be enhanced;drugs in the health insurance directory should be secondarily evaluated regularly;the inno-vative drugs should be given the green channel;innovative drug price negotiation rules should be unified to promote drug informa-tion sharing.
