1.An in vitro blood compatibility assessment on the adsorptive resin in hemoperfusion filter cartridges.
Chinese Journal of Medical Instrumentation 2013;37(6):444-446
OBJECTIVETo investigate necessity of the further processing for adsorptive resin material.
METHODSAccording to GB/ T 16886.4, coagulation tests, haematology tests, in vitro spontaneous platelet-adhesion test and complement activation tests were conducted respectively to assess the in vitro blood compatibility of adsorptive resin material.
RESULTSIn comparison with polypropylene, he adsorptive resin material appears to be a very slight activator to the endogenous blood coagulation system, it can inhibited the exogenous blood coagulation system very significantly (P < 0.01), it can adhere to fibrinogen, red blood cells, reticulocytes very significantly (P < 0.01), and platelet significantly (P < 0.05). The adsorptive resin material is also revealed to be a very significant activator (P < 0.01) to the complement system.
CONCLUSIONSThe in vitro blood compatibility assessment witnesses that it is very necessary for the adsorptive resin material to go through the certain special processing(such as the surface modification and the microencapsulation technology, etc) before its application to human being.

2.Clinical research on preoperative interventional chemotherapy for uterine cervical cancer
Journal of Chongqing Medical University 1986;0(02):-
Objective:To discuss the clinical effect of preoperative interventional chemotherapy and pathological changes in uterine cervical cancer.Methods:preoperative interventional chemotherapy by femoral intubatton were done in 21 patients with uterine cervical cancer.The project of chemotherapy was bleomycin 45mg and cisplatin or oxaliplatin 80mg/m2.Rusults:21 cases of uterine cervical cancer including 7 cases ofⅠstage and 14 cases of Ⅱstage received one or two times of preoperative interventional chemotherapy.All of the patients successfully completed cervical cancer radical therapy.All of the specimens were sent for pathological examination.A lot of lymphocyte cells infiltration and necrosis were found in the cancer tissues.Conclusion:preoperative interventional chemotherapy for uterine cervical cancer proves to reduce the local cancer size as well as decrease the bleeding of cancer.The patients can receive cervical cancer radical therapy after the interventional chemotherapy.
3.Affinity Selection of Human ScFv Against Botulinum Neurotoxin Serotype A
Microbiology 1992;0(01):-
In this work, rare specific binders to botulinum neurotoxin antigen were selected from human phage immunized library through three rounds of panning in vitro. Of them, clone ScFvB17 is of high affinity and specificity to target antigen. B17 is of 750bp encoding 250 amino acid. Analysis results of gene structure showed V-genes of B17 belonging respectively to VH4 or? chainⅡ family are new antibody Fv genes. More important result showed that recombinant ScFvB17 expressed in E.coli could bind specific for neurotoxin competing with antiserum. Successful selection of human phage antibody library and obtaining specific ScFv against botulinum neurotoxin serotype A provide useful materials for further study on detection of neurotoxin and human engineering therapeutic antitoxin.
4.Progress in pharmacokinetic of transdermal drugs
Chinese Journal of Clinical Pharmacology and Therapeutics 2004;0(11):-
In this paper, some study methods of pharmacokinetic, the explanation ways of data and experimental methods of transdermal therapeutic system(TTS) were described. The advancement of modern science accelerates the development of pharmacokinetic of TTS and makes more progress in this field.
5.Analysis of cornual pregnancy in 21 patients
Journal of Chongqing Medical University 1987;0(01):-
Objective:To discuss the diagnosis,treatment of uterus cornea pregnancy.Methods:Retrospective analysis was made in 21 cases of uterus cornua pregnancy is recent 10 years.Results:8 cases were diagnosed uterus cornua,9 cases were misdiagnosed ectopic pregnancy,1 case was misdiagnosed rupture of uterus of artifical obortion,1 case was misdiagnosed pregnancy with uterus septus,1 case was misdiagnosed choriocarcinoma.Surgical treatment was done in 19 patients,and the other 2 cases received conservative therapy.Conclusion:Cornual pregnancy is often misdiagnosed as ectopic pregnancy or other diseases.More careful gynecological and transobdominal ultrasound examination will improve the accuracy of diagnosis.
6.Clinical value of procalcitonin on early diagnosis of sepsis
Chinese Journal of Primary Medicine and Pharmacy 2014;(14):2112-2113,2114
Objective To study the clinical value of procalcitonin on early diagnosis of sepsis .Methods 60 patients who entered ICU were enrolled in the present study were chosen .The change of procalcitonin , CRP, WBC,ESR,GRANR and the highest temperature was observed dynamically with 1 day and 4 days in hospitalization . The patients were ultimately divided into the two groups according to the diagnostic standard of sepsis ,the sepsis group (SIRS group) and infective systemic inflammatory response syndrome group (NONSIRS group).Results After ana-lyzing the processed data,researchers found that PCT of the sepsis group (6.73 ±1.31)ng/mL was higher evidently than that of the SIRS group(0.25 ±0.05)ng/mL(t=3.10,P<0.05),the area under ROC curve of PCT (0.869) is evidently greater than CRP(0.798),WBC(0.737) and ESR(0.394)(P<0.05),which had statistical significance. Conclusion Procalcitonin is a good index of early diagnosis on sepsis ,therefor,its sensitivity and specificity is higher than the other inflammatory indicators .Finally,procalcitonin can be widely used in clinical trial .
7.An Observation of Experimental Autoimmune Uveitis in Guinea Pigs by Light and Electron Microscope
Academic Journal of Second Military Medical University 1985;0(05):-
The soluble antigen was isolated from pig retinal extract by precipitation with ammonium sulfate followed by molecular sieve. 50 ?g S antigen with equal volume complete Freund's adjuvant was injected into double hind foodpads of guinea pigs. Two weeks later, experimental autoimmune uveitis developed. Its pathologic feature is that a great number of lymphocytes infiltrated into chroid which was thickened gradually from anterior to posterior. Inflammatory variation was relative to disease phase. Ultrastructure pathology was characterized by swelling and necrosis in the inner and outer segments of photorecepter cells. This result suggests that S antigen has significant effect on inducing experimental autoimmune uveitis and the outer layer of retina is the sensitive target organ of S antigen.
8.Protective action of TMPustrazine(TMP) on hearts and brains under the condition of acute hypoxia in mice
Chinese Pharmacological Bulletin 1986;0(06):-
AIM Protective action of TMP on hearts and brains under the condition of the acute hypoxia was studied. METHODS On the device of mice acute hypoxia ,ability of tolerancing hypoxia of mice was investigated,and superoxide dismutase(SOD) and malondialdehyde(MDA) and nitric oxide(NO) contents in hearts and brains were measured.RESULTS TMP could make the resisting hypoxia action in mice strengthen significantly,and the action had a does dependent increase. TMP made SOD contents in hearts and brains in does dependent increase;MDA contents in hearts and brains were not notable in low does ,but TMP could decreased MDA contents in hearts and brains in middle and high does ( P
