1.Studies on the anti-idiotypic antibodies against anti-HBs
Chinese Journal of Immunology 1985;0(01):-
Hightiter anti-idiotypic antibodies(Ab_2)sera and two monoclonal anti-idiotypic antibodies (McAb_2)were repared by immunizating syngeneic BALB/c mice wth a complex of 7A_4 monoclonalantibody(McAb_1)against the a eterminant of the Hepatitis B Surface antiger(HBsAg)。Both Ab_2sera and McAb_2 recognize the idiotype of aratope n 7A_4McAb_1.Ab_2 sera contain the antibodiesbinding specially to anti-HBs from other species(guinea pig、onkey、rabbit and goat)and the twoMcAb_2 can not bind to these anti-HBs.Therefore it is thought that the two McAb_ re noninternalimage(Ab_2?)anti-idiotypic antibodies,this study proves that the McAb_1 against he eterminantof the HBsAg are different in their paratope,The McAb_2 can be used to stinguish the parotope onthe McAb_1 as a biological probe.

Objective To find out the factors which influence the establishment of collateral circulation as well as its clinical characteristics by analyzing the sufferers' medical records.Methods Review and collect the records of the first coronary angiography,and we can find the total occlusion of one coronary after coronary angiography.There are 52 cases in which people who suffered the establishment of collateral circulation stay in hospital for treatment.Here,we take 52 cases in which people didn't suffer into comparison and analyze these clinical records.Results Use the Logistic regression method to analyze the relationship between general clinical data,past history,habits,current medication and the establishment of collateral circulation,which relates to the diabetes mellitus anamnesis,exercise and drinking habits,with the regression coefficient is 0.408,0.483,0.197(P
3.Advancement on the use of percutaneous mechanical circulatory support devices in severe cardiovascular diseases
Chinese Critical Care Medicine 2016;28(12):1161-1164
Percutaneous mechanical circulatory support (PMCS) devices are effective in the treatment of patients with cardiogenic shock and acute decompensated heart failure, as a bridge to the recovery of heart function or further treatment. The intra-aortic balloon pump (IABP) is now the most widely used PMCS. New PMCS devices including Transseptal device of Tandem-Heart, transaortic valve device of Impella and extracorporeal membrane oxygenation (ECMO) might provide more effective hemodynamic supports. Doctors should choose appropriate PMCS devices and their working modes, according to patient's clinical conditions, based on the working principles and hemodynamic effects of the devices, in order to achieve the best effects and help patients live through the crisis of diseases.
4.Optimization study on field medical equipment allocation
Chinese Medical Equipment Journal 1989;0(02):-
Network theory is applied to the optimization study on field medical equipment allocation with patient flow and its rate in wartime analyzed. With the application of queuing theory and linear programming, different optimized combinations of evacuation tools are studied, and then static model and dynamic model are established. A calculating table on queue length, service intensity and service desk is put forward to realize rapid evaluation of quantities of required field medical equipment for PLA. Some suggestions are provided to modify the current standard of PLA's basic medical equipment.
5.Analysis of medical humanities connotation in view of value demand by patients
Chinese Journal of Hospital Administration 2016;32(10):782-784
Humanistic quality of medical workers directly affects the quality of medical service and patient satisfaction.In view of patient′s value demand,this paper identified main setbacks in humanistic service in China in the course of medical service.The authors found out the reasons for the lack of humanities quality,and interpreted medical humanistic spirit,medical professional spirit,medical ethics and morality,and connotation of medical law culture.On such basis,the paper unveiled the importance of medical humanities accomplishment in medical practice and medical students′training,proposing to promote the concept of humanistic spirit of medicine and the doctor-patient communication skills.

It was shown that in the stricture on abdominal aorta (SAA) rat myocardiac hypertrophy model,the caudal blood pressure was increased,the wall of left ventricle was thichened, the proliferation of T cell in thymus and spleen was decreased and the content of IL-2 was less than normal. Acanthopanax giroldii polysaccharide (AGPS10mg/kg.d, sc) could harmonize the heightened blood pressure and increase the level of immunity in the body. It was suggested by the result, that AGPS could be used to strengthen the heart function as well as immunity.

Objective To investigate the effect of Honghua Injection on the activity of rat liver CYP2D6.Methods The metabolic rates of probe dextromethorphan(DM) in the blank and Honghua Injection groups(0.9,1.8,and 3.6 mL/kg) in vivo urine and in vitro liver microsome incubated system were determined by high performance liquid chromatography(HPLC).The variation of the metabolic rate of DM represented the effect of Honghua Injection on the activity of rat liver CYP2D6 in vivo and in vitro.Results In vivo and in vitro,the DM metabolic rates of treated groups(1.8 and 3.6 mL/kg) are lower than that in the blank group(P

Objective To explore the relationship of the number of balloon inflations during primary percutanoeus coronary intervention(PCI) with myocardial perfusion and the extent of myocardial necrosis,and to identify the potential clinical efficacy of ischemic postcondioning in patients undergoing Primary PCI.Methods One hundred and fourty patients with ST-segment elevation myocardial infarction(STEMI) who underwent primary PCI were eligibly enrolled for retrospective analysis.The infarct-related artery(IRA) in all patients had to be either left anterior descending artery(LAD) or right coronary artery(RCA) with TIMI 0 flow grade and no collateral filling prior to intervention,and had to be completely reperfused with TIMI Ⅲ flow grade after PCI.Patients with cardiac arrest,cardiogenic shock,previous MI and pre-infarct angina were excluded.Patients were divided into two groups for analysis based on the number of balloon inflations performed during primary PCI:Group A included all patients in whom 1-2 inflations were applied,while patients in Group B received 3 or more inflations.Myocardial perfusion was evaluated by myocardial blush grade and ST-segment resolution.The extent of myocardial necrosis was evaluated by peak values of CK and CK-MB release and predischarge left ventricular ejection fraction(LVEF) measured by echocardiogram.Results The 2 groups showed similar baseline characteristics,while patients in Group B received more balloon inflations than those in Group A(4.7?0.9 vs.1.8?0.2,P0.05),but decreased to 1.65?0.49 mm and 0.98?0.37 mm(P

Objective: To compare the phenotype of induced dendritic cell (DC) derived from peripheral blood of the healthy individuals and the patients with oral carcinoma. Methods:15 patients with oral carcinomal at stages II or above were assigned to study group and 15 cases of healthy volunteers were assigned to control group. Leukocyte were isolated by density centrifugation. Adherent fractions were incubated in present of GM-CSF,IL-4 and TNF-? for 7 days in vitro. The morphological change of the cultured cells was observed by light microscopy and electronic microscopy. The phenotype expressions of CD83,CD1a,CD86, CD80, HLA-DR were analysized by flow cytometry. Results:Typical DCs were obtained from two groups after 7 days culture. The expression rate of CD83,CD1a on DC from healthy volunteers was significantly higher than that from patients (P0.05). Conclusion:DC derived from oral cancer patient' s peripheral blood monocyte might be more matured and is a good cell model for further immunotherapy and research.
