1.Hyperlactatemia and metabolic acidosis in critically ill patient
Chinese Journal of Clinical Nutrition 2011;19(3):183-187
The relationship between hyperlactatemia and metabolic acidosis, which may involve shock resuscitation,homoiostasis, and nutritional support, remains a hot topic. On one hand, increased production of lac-tate due to anaerobic glycolysis during tissue hypoperfusion can aggravate metabolic acidosis; on the other hand,the utilization of lactate at organ and cell levels may lower blood lactate level, and thus alleviate metabolic acidosis.The ultimate blood lactate level depends on the balance of these two action mechanisms.

Chinese Health Economics 2013;(9):50-51
Objective: In order to provide references for drawing up related health policy reasonably, the current status of medical insurance payment in third level hospital. Methods: Through analyzing the payment situation of medical insurance in third level hospital from 2010 to 2012, to understand the related situation of gross prepayment system in large publich hospital since this year. Results: In recent years, the coverage rate of health insurance in the whole city is increasing continuously, while the rising extend of annual gross prepayment limit is not obvious, refusal in medical insurance fund is serious and the accounting method of prepay limit is not scientific. Conclusion: While satisfying the quality of patients’ visiting, it needs to implement gross prepay accounting method, enhance medical management and reduce the economic burden of the hospital.
4.Network pharmacology: new guidelines for drug discovery.
Acta Pharmaceutica Sinica 2010;45(12):1472-7
The development of new drug is not only the main driving force for the development of pharmaceutical industry, but also plays a very important role in the social development. However, with the increasing demands, new drug development is facing great difficulties in recent years. The hypothesis of highly selective single-target is meeting the challenges because of its limitations. Network pharmacology has been one of the new strategies for new drug discovery based on single-target drug research in recent years. This paper focused on the basis of network pharmacology and its research progress, discussed its development direction and application prospects, and analyzed its limitations and problems as well. The application of network pharmacology in new drug development is discussed by comparing its guidelines with those of traditional Chinese medicine theory and Effective Components Group hypothesis of Chinese medicines.

7.Advances in novel anti-OX40 cancer immunotherapy
Chinese Journal of Microbiology and Immunology 2017;37(3):240-244
OX40 (CD134) is a member of the tumor necrosis factor receptors and mainly expressed on the surface of active lymphocytes.Being an important pair of co-stimulatory factors in the process of immune response, OX40 and its ligand OX40L play an important role in inducing anti-tumor immune response.They regulate the immunosuppressive effect in tumor microenvironment and enhance the killing activities of effector cells.Pre-clinical animal studies have shown that agonists for OX40, whether they are used alone or in combination with other treatments, have stronger anti-tumor effects.Several anti-OX40 agonistic monoclonal antibodies (McAb) are currently tested in early phase cancer clinical trials.This review focuses on the advances in anti-OX40 mAbs-based therapy in terms of molecular and biological properties, mechanism of action, monotherapy and combined therapy.
