International Journal of Pediatrics 2014;41(2):138-141
Sepsis,a common clinical syndrome,comparing to septicaemia or bacteremia,has a more comprehensive pathophysiological process.Its pathogenesis is complex,including pro-inflammatory/anti-inflammatory cytokine imbalance,intestinal bacterial translocation,immunosuppression,signal pathway activation,etc.Further study on the pathogenesis of sepsis is the theory foundation to explore the new method of sepsis.The diagnosis of sepsis pathogenesis,treatment principles and common virus infection induced sepsis are reviewed in this paper.
4.Advances in anti-vasculogenic mimicry therapy
International Journal of Surgery 2011;38(4):267-270
Vasculogenic mimicry (VM) is a term that describes a novel form of angiogenesis, channels of which are patterned networks of interconnected loops of periodic acid-Schiff (PAS)-positive extracellular matrix forming by highly aggressive tumor cells instead of endothelial cells. VM is closely correlated with the invasiveness, metastasis and prognosis of related tumors. However, traditional anti-vascular therapies aiming at endothelial cells have no remarkable effects on malignant tumor with VM. Therefore, VM should be an important factor to consider in design of anti-angiogenesis therapies of highly aggressive tumors and it is expected to become a potential target for tumor therapy. Some recent progresses of anti- vasculogenic mimicry therapy are reviewed in this article.
5.Study on change of hypoxia stress peptide and nitrogen monoxidum in peripheral blood from the entering mountain rapidly man and its significance
International Journal of Laboratory Medicine 2009;30(10):937-939
Objective To analyze the concentration changes of serum hypoxia stress peptide (HSP)and plasma nitrogen monoxidum(NO)in the entering mountain rapidly man and to explore the importance of HSP and NO in adaptation of man to altitude hypoxia.Methods The levels of serum HSP and plasma NO2-/NO3-were measured from 106 entering mountain rapidly men,105 altitude in habitant,105 altitude immigrant and 104 plain healthy controls,respectively by chromatometry and NO2-/NO3-reagent.Furthermore,the content of serum HSP was determined in 106 entering mountain rapidly men,respectively at the time of 24 h,48 h,76 h,l week and 1 month after entering mountain.Results The level of serum HSP was significantly higher in entering mountain rapidly men than in habitant,immigrant and plain controls(P<0.05),while there was no statistical difference between in habitant,immigrant and plain controls(P>0.05).At 24h after entering mountain rapidly,the level of serum HSP was significantly increased and reached the peak.At 48h and 76h,it was slightly decreased,but still maintained a high level.At 1 week and 1 month,it gradually and significantly went down,but was still significantly higher than that in plain controls.Similarly,the level of plasma NO2-/NO3-was significantly elevated in entering mountain rapidly man,compared with inhabitant,immigrant and plain controls(P<0.05).It was lower in inhabitants and immigrants than plain controls,but the difference was not statistically significant(P>0.05).Conclusion The present results demonstrated that the levels of serum HSP and plasma NO were significantly up-regulated in healthy adults after en tcring mountain rapidly in order to adapt to altitude stress,and restored gradually to the normal level as time went by.
6.Study of JCBI spontaneously producing a suppressor factor
Chinese Journal of Immunology 1985;0(03):-
JCBI is a glioma eell line established in our department. JCBI cells spontaneously produce a factor inhibiting blastogenic responses of mouse thymocytes and the IL-2 dependent T cell growth of mouse spleen lymphoblast, without inhibiting spontaneous proliferation of mouse thymocytes. The inhibiting activity is high after 72 hours of passage. Physicochemical characterization shows that the factor is nondialyzable. partially inactivated at 37℃ 48 hours and almost inactivated at 56℃ 30 min. But the factor is stable at 4℃ for 2 weeks and in freeze-thawing. The molecular weight of the factor is approximately 10 kd as estimated by gel filtration. The factor may contribute to the impaired immunosurveillance and to the cellular immunodeficiency state in the patients.

Journal of Guangzhou University of Traditional Chinese Medicine 2000;0(04):-
Objective The correlation of union of femoral shaft fracture with selection of therapies was analyzed to explore the importance of protecting the periosteum and soft tissue,and to observe the influence of Chinese medicine.Methods A retrospective study was carried out in 478 femoral shaft fracture patients hospitalized in Zhongshan Hospital of TCM from 2001 to 2008.According to the selection of therapies,the patients were separated into conservative group(N=198) and operative group(N=280).The conservative group was then divided into two subgroups: conservative treatment alone(N=105),and conservative treatment combined with oral use of Chinese medicine(N=93).The operative group was divided into three subgroups: open reduction and fixation with dynamic compression plate(N=113),open reduction and fixation with limited contact-dynamic compression plate(N=98),and closed reduction and fixation with intramedullary nail(N=69).The correlation of union of femoral shaft fracture and selection of therapies was analyzed.Results The union rate in the conservative group was higher than that of the operative group(P
9.The application of comprehensive prevention measures for the ventilator associated pneumonia in the clinical
Chinese Journal of Postgraduates of Medicine 2014;37(z1):20-23
Objective Statistics and analyze the effect of comprehensive prevention measures for the ventilator associated pneumonia (VAP) morbidity and mortality,and investigate its actual applicate situation in the clinical.Methods Statistics and analyze the clinical date of 183 cases of our ICU mechanical ventilation patients in 2012 (group A),including morbidity,mortality,time of endotracheal intubation,length of stay and the primary pathogenic bacteria,and to compared with the relevant clinical data of 192 cases of our ICU mechanical ventilation patients in 2011 (group B),summarize and analysis the actual applicate situation of the comprehensive prevention measures in the clinical through the data contrast.Results The incidence of VAP in group A was lower than that in group B [31.7%(58/183) vs.58.3%(112/192)] (P < 0.05),but the mortality was no statistical difference in both groups (P > 0.05) ; the endotracheal intubation time and the average length of stay in group A were less than those in group B [6.3 d vs.10.6 d,7.6 d vs.11.9 d](P<0.05); the main pathogenic bacterium of VAP with mainly gram-negative bacilh.Conclusions Comprehensive prevention measures can effectively reduce the incidence of VAP,but the mortality rate has no significant effect,need further clinical research;comprehensive prevention measures to reduce patients with tube time also confirm its effectiveness.Comprehensive prevention measures are economical and practical,is worth in clinical promotion.
10.Combination use of diltiazem and nitroglycerin in preventing radial artery spasm in performing coronary angiography:observation of its efficacy and safety
Journal of Interventional Radiology 2014;(6):474-476
Objective To investigate the efficacy and safety of combination use of diltiazem and nitroglycerin in preventing radial artery spasm in performing coronary angiography via radial artery access. Methods During the period from Dec. 2012 to June 2013 at authors’ hospital, coronary angiography via radial artery access was carried out in a total of 200 patients. The patients were randomly divided into 2 groups: nitroglycerin group (n = 100) and combination group (n = 100). After successful placement of catheter sheath 200 μg of nitroglycerin was injected through the sheath in the patients of the nitroglycerin group, while 200 μg of nitroglycerin together with 2 mg diltiazem was injected through the sheath in the patients of the combination group. The heart rate , blood pressure and electrocardiogram were recorded with an electrocardio-pressure monitor before the injection as well as at 2, 5, 15 and 30 minutes after the injection. The occurrence of radial artery spasm and patient ’s general condition were also under observation. Results Radial artery spasm occurred in 5 patients of the combination group , while it occurred in 13 patients of the nitroglycerin group, the difference between the two groups was statistically significant (P < 0.05). No significant difference in heart rate and electrocardiogram existed between the two groups (P > 0.05). Conclusion For the coronary intervention via radial artery access , combination use of diltiazem and nitroglycerin can more effectively prevent the occurrence of radial artery spasm. Besides , combination use of diltiazem and nitroglycerin has no obvious effect on the heart rate , the blood pressure and the electrocardiogram.
