Objective: To detect the expression and distribution of activated cytotoxic cells in types of lymphoma with tissue microarray,and provide evidences for clinical treatment and prognosis. Methods: Immunohistochemical staining by S-P technique was used for detecting the expression and distribution of perforin and granzyme B in lymphoma tissue microarray,composed of 60 samples of lymphoma tissue.10 NK/T-cell lymphoma routine sections were used for relative research,and 10 reactive hyperplasia were used for comparison. Results: In the tissue microarray,samples originated from intranode and extranode were 48 and 12,respectively;consisting of 42 B-cell lymphoma,16 T-cell lymphoma(10 PTCLs,2 NK/T-cell lymphomas,2 lymphoblastic T-cell lymphomas,2 anaplastic large cell lymphomas),2 Hodgkin's disease.42 samples of B-cell lymphoma cells were negative in perforin and granzyme B.In 10 samples of peripheral T-cell lymphoma,perforin and granzyme B positive were 8 and 9,respectively,but the positive cells were no tumor cells.In 12 samples of NK/Tcell lymphoma(2 in the tissue microarray,10 routine sections),both perforin and granzyme B were strongly positive.B-cell lymphoma,T-cell lymphoma and NK/T-cell lymphoma differed significantly(P

OBJECTIVE:To perfect public participation system of food and drug safety in China and establish“society multi-governance”of food and drug safety. METHODS:The problems of public participation in food and drug safety administration were analyzed in China. Referring to the experience of USA,Japan,South Korea and other developed countries in stage of food and drug safety legislative decision-making,regulation and enforcement and dispute settlement,the countermeasures were put forward to perfect public participation system of food and drug safety. RESULTS & CONCLUSIONS:The public is in a passive position and shows weak right of speech in legislative decision-making stage;the public is not active and shows weak awareness of partici-pating in management in regulation and enforcement stage;public interest litigation system in dispute settlement stage has not been established. Those problems impede the generation of“society multi-governance”of food and drug safety in China. In United States,Japan,South Korea and other developed countries,the position and right of the public participation can be guaranteed com-pletely through establishing complete legal system,strengthening government information transparency,improving complaints sys-tem and public interest litigation system,etc. Our country can perfect the system of public participation in the food and drug safety and promote the generation of“society multi-governance”of food and drug safety by detailing the regulations in legislative deci-sion-making,emphasizing the information opening and feedback,strengthening the propaganda of public responsibility conscious-ness,setting up scientific food and drug safety complaint and reparting system and establishing public interest litigation system.

OBJECTIVE:To provide reference for rational drug use. METHODS:107 patients with drug-induced liver injury (DILI)admitted to liver disease department of our hospital during Jan. 2011 to Dec. 2015 were divided into TCM group and chemi-cal medicine group according to the type of medicine. DILI clinical characteristics,prognosis,medicine types of DILI were com-pared and analyzed between 2 groups. RESULTS:47 cases of DILI were induced by TCM,which mainly were health care and body beauty medicines(19.1%),rheumatism and arthritis medicines(14.9%)and dermatological medicines(10.6%). 60 cases of DILI were induced by chemical medicine,which mainly were antineoplastics(21.7%),antimicrobial(20.0%)and antituberculot-ics (11.7%). Gender,average age,the time from primary medication to disease attack and clinical classification were no signifi-cant difference between 2 groups(P>0.05). The clinical manifestations of the 2 groups were similar,except that fatigue was more common in the TCM group,with statistical significance(P<0.05). The liver function indicators of TCM group as ALT,AST, TBIL and ALP were higher than those of chemical medicine group,while ALT and TBIL were significantly different between 2 groups(P<0.05). The liver injuries were more serious in the TCM group than in chemical medicine group,with statistical signifi-cance(P<0.05). After treatment,the prognosis and the prognosis of liver function indicator in 2 groups were not statistically sig-nificant(P>0.05). CONCLUSIONS:Doctors and pharmacists should cooperate to master medication indication strictly,develop ADR monitoring and conduct blood concentration monitoring of high-risk DILI medicines,especially the hepatotoxicity of TCM so as to reduce the occurrence of DILI and guarantee the safety of clinical drug use.

OBJECTIVE:To explore the effect of different plasmapheresis supplement timing on therapeutic efficacy of toxic liver injury. METHODS:96 patients with toxic liver injury and divided into group A,B ,C and D with 32 cases in each group ac-cording to different plasmapheresis supplement timing. All patients received plasmapheresis supplement based on routine treatment. In group A,synchronized fluid replacement was 100% fresh plasma;in group B,synchronized fluid replacement was 40% normal saline firstly,and then 60%fresh plasma;in group C,substitute liquid was given till the in vitro blood reached 12%of circulation amount,supplement order as 40% normal saline for the first supplement,and then add 60% fresh plasma. The clinical symptoms and signs,liver function,prothrombin activity and blood biochemical indicators were observed in each group before and after treat-ment. RESULTS:Plasmapheresis supplement had good therapeutic efficacy on toxic liver injury;but the time of clinical symptoms and signs disappearance in group C was significantly shorter than that in group A and B,and the group B was significantly shorter the group A,with statistical significance (P<0.05). The plasma bilirubin,prothrombin activity,albumin levels of 3 groups after treatment were significantly better than before,with statistical significance(P<0.05);the group C was better than the group A and B,and the group B was better than the group A,with statistical significance(P<0.05). Compared with before treatment,the lev-els of AST and ALT in 3 groups decreased significantly after treatment,with statistical significance(P<0.05);the group B and C were better than the group A,with statistical significance(P<0.05);the group B and C was similar to each other,without statisti-cal significance(P>0.05). CONCLUSIONS:Different plasmapheresis supplement timing have different effect on toxic liver injury. The supplement method that giving 40% normal saline for the first supplement,and then add 60% fresh plasma when in vitro blood reach 12%of circulation amount has more significant effect.

The right of informed consent is composed of two closely connected rights-the right to know and the consent right.The right to know is prerequisite and foundation that the consent right depends on,and the consent right is also the value embodiment of the right to know.The main purpose of emphasizing patient's informed consent right lies in through entrust with the medical establishment and the medical staff's corresponding informing obligation,helping patients understand potential risks,cost so that they can make free choice.It can maintain patient's benefit,change patient's weak-trend status.Medical consent right is the patients' right to accept treatment or not and chooses options after they are fully aware of the information about their diagnosis and treatment options.Medical consent as an important right of patients is receiving increasing attention.Based on the achievements of predecessors,this article discusses how to protect patient's right of informed consent better.
