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

Livin is the inhibitor of apoptosis proteins (IAPs), a new member, in most malignant tissues of high expression, and its main function is to inhibit cell apoptosis. Apoptosis and tumor cells is closely related to the occurrence and development, more on which the survival of tumor angiogenesis. Vascular endothelial growth factor (VEGF) is one of the strongest of vascular growth factor, and almost all human tumors and tumor cell lines have over-expression of it. Livin and VEGF protein expression in tumor was summarized.

Objective To explore 24-hour ambulatory blood pressure of patients with cervical spinal cord injury. Methods 42 patients with cervical spinal cord injury and 45 patients with thoracic-lumbar spinal cord injury were included. Their 24-hour ambulatory blood pressures were monitored. Their day systolic blood pressure (dSBP) and day diastolic blood pressure (dDBP) when seating and standing, night SBP and DBP, and SBP descending rate at night were compared. Results There were significant differences in dSBP and dDBP when standing, and SBP descending rate at night between 2 groups (P<0.01). There was significant difference in dSBP between seating and standing position in patients with cervical spinal cord injury (P<0.01). Conclusion There is orthostatic hypotension in cervical spinal cord injury patients and their SBP descending rate at night is upside down.

Objective To discuss the early clinical management of the pa tients with traumatic hemipelvectomy. Methods A case was reported and literature reviewed. Results The patient was a 4-year-old boy who incurred a left groin and proximal thigh crush with nearly complete transection of this extremity and arrived at our hospital 7 hours after injury. After the vital signs were stabili zed with reasonable wound care and 2 hours of fluid resuscitation, the patient r eceived a thorough debridement and the hip disarticulation and fixation of pubic symphysis. The postoperative course was relatively smooth. While the successful treatments of this patient corresponded to the experiences in the literature, s pecial considerations regarding this severe injury were discussed. Conclusion Im mediate prehospital hemostasis by local pressure, rapid transport, aggressive in itial resuscitation, early recognition of the severity and prompt decision to co mplete the amputation, and attention to details in the rehabilitation phase are necessary for successful management of these patients.

Objective To discuss the reasons of death in the in-patients with percutaneous coronary intervention(PCI).Methods Retrospective analysis was done in 33 cases who died in or after the procedures among 3 252 in-patients with PCI.Results 4 patients died in procedures and the others died after procedures.The major reasons of death in order were:cardiogenic shock,ventricular fibrillation,acute left heart failure,multiple organ failure,heart rupture and acute renal failure.The in-hospital mortality rate was 1.01%.Conclusion The major reasons of death of patients with PCI are cardiogenic shock,ventricular fibrillation and acute left heart failure.Taking some measures will reduce the in-hospital mortality rate.

While the basic concept of saving life and decreasing disability h as not changed in the management of polytrauma, the timing and strategies of tre atment have been gradually modified. Damage control is one of the new strategies , and its application in orthopedic traumatology is known as damage control orth opedics. Damage control orthopedics involves formalized three stages in the mana gement of fractures of long bones and pelvis. Stage 1 consists of temporary fixa tion of the unstable fractures and hemostasis. Stage 2 comprises resuscitation, warming, oxygen delivery and administration of coagulation factors to the patien t in the intensive care unit. In Stage 3 definitive fixation is done for the fra cture. Indications of damage control orthopedics: for patients with polytrauma w hose conditions are unstable or in extremis the damage control strategy is recom mended. For the borderline patients early total care may be applied, but the sur gery should be performed with great caution. It has to be converted to the damag e control strategy if conditions of the patient deteriorate during the operation . Since damage control orthopedics is an evolving practice, further work is need ed to enhance its effectiveness and to reduce the incidence of ARDS and MOF.

Modern Chinese Orthopaedic traumatology has stemmed from the orthopaed ics of Traditional Chinese Medicine(TMC)and western orthopaedics.On the one hand,with a long history and its unique system of theory and treatment,TMC orthopaedics h as made a great con-tribution to the development of modern Chinese orthopaedic traumatology.On the other hand,the introduction and development of western medicine have dramatically pro moted the development of modern Chinese orthopaedic traumatology.Modern Chinese surgeons of orthopaedic trauma have accomplished numerous successful f irst cases in the world since 1950s an d have thus expanded their professional influence.At pr esent,the Chinese orthopaedic trau ma community has grown much stronger and established its ow n academic associations and journals.More and more de-partments of orthopaedic traumatology have been successively establis hed as an independent en-tity in large and middle-sized hospi tals in China.So far,the Chinese orthopaedic trauma com-munity,on the whole,has reached the international level,but there are q uite a lot to be improved in the aspect of treatment.To end the backwardness,in the future Chinese orthopaedic trauma community should make great efforts in education of orthopedists on comp rehensive knowledge,establishment of formal profession al training system,national standardization of orthopaedic procedures in clinical diagnosis an d treatment,active membership of re lative international aca-demic associations and increasing p rofessional exchanges with international counterparts,as well as in research and development of operative techniques and fixators.All these will be the main strategies and developmental trends in the future for Chinese orthopaed ic traumatology.

Objective: To study the effects of different restorati ve materials on the health of periodontal tissue. Methods: A total of 40 posterior teeth were divided into four groups with 10 in each. Sil ver amalgam, glass ionomer cements, GlasIonomer Cement FX and light curing Mic roglass composite resin were used to restore Class Ⅱ cavity in each tooth of th e 4 groups respectively . 6 months after restoration gingival cervical fluid (GC F) was collected , GCF aspartate aminotransferase (GCF AST) level was tested a nd plaque index was assessed for each case. Results: The s ilver amalgam and light curing Microglass composite resin groups presented less amount of GCF ( P

Objective To study the effect of pravastatin on the patients with chronic renal failure(CRF)and normal blood lipid. Methods 48 cases of CRF patients with normal blood lipid were randomly divided into two groups. 26 patients of group 1 were given pravastatin besides basic treatment. 22 patients of group 2 were only given basic treatment. The treatment was consecutive for one year. Blood lipid, serum creatinine, clearance rate of serum creatinine(Ccr), urinary retinol-binding protein(RBP) and protein amount in urine were tested respectively before treatment and one month, six months and one year after the treatment. Results Compared with the patients of group 2, blood lipid, urinary RBP and total urinary proteins and serum creatinne decreased, and Ccr increased in the patients of group 1. Conclusion Pravastatin can postpone the renal dysfunction of the CRF patients with nomal blood lipid.

Objectives To explore the effects of hemodialysis on oxidizing stress and plasma nitrogen monoxide (NO) levels in maintenance hemodialysis patients. Methods 67 maintenance hemodialysis patients (male 39, female 28, and mean age 58?13y) were enrolled in this study. Serum malondialdehyde (MDA) level was measured by colorimetry, and plasma NO level was determined by enzymatic method. The MDA and NO levels before and after hemodialysis were measured in 48 cases of the patients. Results After hemodialysis, the serum MDA levels significantly increased, and the plasma NO levels decreased. The patients with cardiovascular diseases had lower NO levels and higher MDA levels than the patients without ones before hemodialysis. The serum MDA levels of the patients using biological incompatible dialysis membrane increased after hemodialysis. Conclusion Hemodialysis treatment, especially using biological incompatible dialysis membrane increased oxidizing stress and decreased plasma NO levels in maintenance hemodialysis patients, and was significantly correlated with the pathogenesis of cardiovascular diseases.
