Objective To analyze the pathophysiological variation in patients with penetrating cardiac trauma (PCT) and discuss the classified treatment strategies.Methods A retrospective analysis was conducted on pathogenetic condition,medical interventions and other clinical information of 133 PCT patients.The patients were divided into four groups in accordance with their symptom classification on arrival at emergency department,including sub-clinic type,cardiac tamponade type,hemorrhagic shock type and agonal type.Meanwhile,the patients were classified into three groups according to their pathogenesis phase,including sub-clinical phase,clinical phase and agonal phase.Development characteristic of patients' condition in each group was investigated in each time point by survival analysis.Impacts of medical interventions on prognosis of those patients were analyzed,such as pericardial space exploration,emergency room thoracotomy (ERT),operating room thoracotomy (ORT).Results Some patients at sub-clinical phase were aggravated into clinical phase or agonal phase,as well as some patients at clinical phase were aggravated into agonal phase during in-hospital treatment.There were significance differences of posttraumatic suvival course among the four groups,namely sub-clinical type,cardiac tamponade type,hemorrhagic shock type and agonal type (P ＜ 0.01).The differences of posttraumatic survival course were also significant among the three groups,namely sub-clinical phase,clinical phase and agonal phase (P ＜ 0.01).Conclusion Clinical symptom classification (or pathogenesis phase) of PCT may not be always unchangeable,thus it is recommended that PCT patients should be treated based on their clinical symptom classification or patbogenesis phase at consultation.

Objective To study the clinical characters of coronary artery triple vessel lesion, and to provide a theoretical basis for the therapy to the disease. Methods The clinical data of 68 cases of coronary artery triple vessel lesion (group A) and 71 cases of coronary artery of single or double vessel lesion (group B) were analyzed retrospectively. Results The related risk factors (hypertension, hyperlipidemia, diabetes and smoking) and the clustering of these factors were not significantly different between the two groups (P>0.05). While the positive rate of the exercise stress test existed remarkable difference between the two groups(P<0.01).The extreme differences between the two groups existed also in the cases of building collateral circulation (P<0.001), and in LVEF and LVEDP (P<0.0001) demonstrated by left ventricular angiography. The majority of the coronary artery lesion in group A was on level Ⅳ, and much more lesions of level Ⅲ and level Ⅳ occurred in group A than in group B. Most patients in group A accepted the coronary intervention, while after operation the angina pectoris emerged in a high rate, then the rebuilding of coronary circulation had to be done. Conclusions The best treatment for the patients with coronary artery triple vessel lesion should be the operation of coronary artery bypass graft (CABG), if it's possible.

Objective To summarize the study on the feasibility of celiac axis ligation. Methods Literatures about celiac axis ligation were reviewed retrospectively. Results Celiac axis branches included common hepatic artery, splenic artery, left gastric artery which had many variation and collateral flow between celiac and mesenteric vessels by gastroduodenal artery and pancreaticoduodenal artery. Celiac axis could be possibly ligated without obvious complications in patients who had celiac axis injuries, celiac artery aneurysms, upper gastrointestinal haemorrhage, excision of carcinoma around the celiac axis and portal hypertension. However, gallbladder necrosis or perforation, focal infarction of the liver even higher mortality had also been reported. Conclusion Celiac axis ligation should not be performed routinely, but it is surgically possible and may be a life saving approach in certain circumstances.

Ehrlich's ascites cancer (EAC) in BALB/C mice by ip transplantable EAC cell is reproduced by us. The change of serum malondialdehyde(MDA), plasma cellular cAMP and adenylate cyclase (AC) are examined in the early, middle and late phase of mice bearing EAC respectively in comparison with that of control group. Results indicate that serum MDA in mice bearing EAC is continuously increased with the progress of the disease in the remarked ways in comparison with the control group. Whereas the plasma cAMP in the mice bearing EAC is markedly decreased in that order. Relation between the change of serum MDA and the cellular cAMP, AC or plasma cAMP shows a significant negative correlation efficiency (P

Nasopharyngeal carcinoma (NPC) in BALB/c nude mice (NM) was re-produced by hypodermic implanting human CNE-2 cell to the right-side of neck-backposi-tion. The changes of plasma malondialdehyde (MDA) and cAMP/cGMP ratio in NM bea-ring human NPC were examined. Meanwhile, we observed that tumor's size, plasma MDAand cAMP/cGMP ratio in NM bearing human NPC were affected by polysacchoridopetide(PSP). Results indicated that in comparison with the control group, NM bearing humanNPC showed a marked increase in plasma MDA(18.25?1.37 nmol/ml),cAMP/cGMP ratio(4.55?0.35), a marked decrease in plasma, cAMP (71.83?8.51 pM/ml) and cGMP(15.77?0.65 pM/ml), both high or low-concentration PSP inhibited NPC growth.Rate of inhibition was between 59.58 to 95.53 percent. PSP decreased plasma MDA,elevated cAMP, cGMP's levels and recovered cAMP/cGMP ratio. Our results suggestedthat the elevated level of MDA in NM bearing human NPC was closely associated withthe presence of NPC. PSP had antitumor effect, probably by means of decreasing freeradicals and recovering cAMP/cGMP ratio.
