OBJECTIVETo study the ischemic times of the main artery injury in the limbs and the influence on the limbs survival rate, and to analyze the reasons for the formation of the ischemia time.

METHODSFrom June 1996 to November 2012, 83 patients with completely severed limb main artery treated in our hospital were retrospectively studied. There were 77 males and 6 females, including 81 adults (ranging in age from 16 to 52 years old, with a median age of 35 years old) and 2 children (4 and 5 years old respectively). Seventy-five patients were treated with end to end anastomosis, 7 patients were treated with great saphenous vein transplantation, and 1 patient was treated with artificial blood vessel transplantation. The prior to admission ischemia time, after admission ischemia time and total ischemia time for successful and unsuccessful patients, as well as the causes of the formation of the ischemia time were studied. Limb survival rate of different ischemic time was counted. Sharpness injury or blunt injury ischemia time and amputation rate were researched statistically. All data were analyzed using SPSS statistical software.

RESULTSThere were 72 limbs survived, 11 amputated. The average ischemia time was (7.45±5.94) h for limb-salvage group and (13.73±14.00) h for amputation group. Prior to admission ischemia time between amputation and limb-salvage group had no significant difference. After admission the ischemia time in amputation group was longer than limb-salvage group. The amputation rate for ischemia time 21 to 44 h group was higher than other three groups (≤ 5 h, 6 to 10 h, 11 to 20 h) (P=0.023, 0.038, 0.044). Amputation reasons can be divided into anastomosis failure in the operation, vascular thrombosis 2 to 4 days after operation and late infection.

CONCLUSIONVascular injury limbs can tolerate longer ischemia time and the limb salvage succeed. Only too long ischemia time (> 20 h), limb amputation rate increases significantly. The main cause of long time ischemia is delayed diagnosis in the hospital. Whether limb-salvage success mainly depends on the degree of trauma and the quality of the anastomosis than ischemia time.

OBJECTIVETo study the influence of actual defect length and gap width of the limbs main artery on the method selection of repairing and reconstruction.

METHODSRetrospective study was carried out for 32 patients with extremity main artery injury from 1996 to 2009, including 30 males and 2 females; 30 adults with an average age of 36 years old ranging from 18 to 51 years, 2 children of 4 and 5 years old respectively. Injured body parts involved axillary artery in 4 cases,brachial artery in 7 cases,radial artery in 2 cases, femoral artery in 4 cases, popliteal artery in 13 cases, posterior tibial artery in 2 cases. Main arterial injury defect gap width of all cases were observed and the reasons were analyzed. All cases were repaired by the method of end to end anastomosis after vessels stretch.

RESULTSThe artery defect width was 3 cm to 7 cm with an average of (4.375 +/- 1.200) cm. Defect width of the upper extremity brachial artery and axillary artery group was (5.73 +/- 0.63) cm,the lower extremity femoral and popliteal artery group (3.80 +/- 0.73) cm, the posterior tibial artery group (3.25 +/- 0.35) cm, the radial artery group (3.00 +/- 0.00) cm. Defect width of upper extremity brachial artery and axillary artery group was larger than that of the other three groups (P < 0.01). End to end anastomosis was performed successfully in all cases. Blood supply recovered well. Because of the severe limb infection 2 patients had amputation in the late. All patients received follow-up. The patients without fracture were followed up to 2 weeks postoperatively, all patients with fractures were followed up to 1 year at least. Limb blood supply was good in all patients during the follow-up.

CONCLUSIONBlood vessel defect gap width is different from the actual vessel defect, but is larger than the actual vessel defect. Misjudgment of the vascular defect length will lead to more vascular transplantation. The vast majority of vascular defect can be directly repaired by the method of end to end anastomosis after the vessel free and stretch.

Objective To study the effect of thoraco-tumba fracture with pedicle scre system. Methods Forty-two cases with thorac-lumbar fractute treated with pedicle scre system were reviewed,their clinical featuers,x-ray and CT images before and after operation were analyzed. Results With follow-up of two months to three years after operntion,height of vertebra was completely restored on thirty-four cases,neurological function recovered in various degree according to the Frankel criteria in all cases. Conclusion Pedicle scre system is an effective method for treatment of thoraco-tumbar fracture.

Objective To determine the influence of total glucosides of paeony (TGP) on bone density, protein level of skeletal muscle and relative cytokine of osteoporotic rats. Methods Six-month-old SD rats were shamed as control (8 rats) or were ovariectomized (24 rats). The ovariectomized (16 rats) +TGP low dose and high dose group were treated with 50 mg/(kg?d) TGP and 150 mg/(kg?d) TGP respectively for 12 weeks. After the animals were sacrificed, IL-6, TNF-?, IGF-1, TGF-? in serum, protein level of skeletal muscle in right quadriceps femoris, and bone density of right femur and lumbar vertebra were determined. Results Compared with the ovariectomized group, the bone density and the protein level of skeletal muscle in TGP group increased significantly from the baseline (P

Results The positive positive expression rate of ATM protein in the early esophageal squamous cell carcinoma tissue and adjacent normal tissue were 65% and 95% respectively ,which were statistically different (P= 0 .044) .Conclusion The ATM protein ex-pression in esophageal squamous cell carcinoma tissue declined .The detection of ATM protein in esophageal squamous cell carcino-ma tissue could become a reliable method for early diagnose of esophageal squamous cell carcinoma .

ObjectiveTo investigate the effect of cardiopulmonary bypass (CPB) on the secretory function of islet cells in rabbits.MethodsTwenty adult New Zealand white rabbits of both sexes,weighing 2.5-3.0kg,were randomly divided into 2 groups ( n =10 each):sham operation group (group S) and CPB group.The rabbits were anesthetized with 3％ pentobarbital sodium 30 mg/kg.Blood samples were collected from the left femoral artery at 5 min after anesthesia (T1),immediately before CPB (T2 ),immediately after aortic clamping (T3 ),and at 5,35 and 75 min after aortic unclamping (T4-6) in the two groups for determination of levels of blood glucose,insulin and glucagons.Insulin resistance index was calculated.ResultsCompared with group S,the blood glucose concentration and levels of insulin and glucagons and insulin resistance index at T3-6 were significantly increased in group CPB ( P ＜ 0.05).ConclusionAlthough increase in blood glucose enhances the secretion of insulin in islet β cells,hyperglycemia cannot be compensated completely by the increased insulin during CPB in rabbits.The increase in blood glucose may be related to islet α cell resistance.

Penetration enhancers are substances to improve the rate or amount of transdermal permeation which is an important factor in transdermal drug delivery systems (TDDS). Recent researches have found that some of the new penetration enhancers have a higher penetration-effect, little irritation, fewer adverse reactions, and stable properties. In this article, domestic and foreign research reports on penetration enhancers have been collected and summarized. The research progress of penetration enhancers were reviewed, with a purpose to provide a reference for reasonable selection of penetration enhancers.

Objective To explore the effect of clinical pharmacist on clinical rational use of antineoplastic drugs after participating in treatment group.Methods Retrospective research was used.According to whether there was a clinical pharmacist directly or indirectly involved in,all medical teams of the oncology department were divided into intervention group,advisory group and control group in our hospital.Intervention group was the medical team that had a specialist clinical pharmacist who could intervene irrational use of antineoplastic drug in the treatment on the spot.Advisory group was in the same area with the intervention group,and didn't have a specialist clinical pharmacist, but used to communicate with clinical pharmacist and take his medication advice,where clinical pharmacist indirectly involved in treatment.The control group was the medical group in the other area without clinical pharmacists of oncology department.The control group one and two were with the most beds among the control group.Randomly selected lung cancer,breast cancer,esophageal cancer,gastric cancer,colorectal cancer,gynecological cancer,liver/gallbladder/pancreatic cancer and other tumors patients from intervention group,advisory group,control group one and control group two,from January 2015 to December 2015,10 copies of each case,80 copies of each group.And antineoplastic drugs were commented specially.The information such as sex,age,clinical diagnosis,irrational antineoplastic drug use,adverse reaction and unexpected events and hospitalization time were recorded.Results The rate of irrational antineoplastic drug use of the intervention group (41.25%)was lower than the advisory group(80%),and was significantly lower than two control groups(147.50%,161.25%),advisory group was also lower than two control groups,but no significant differences between the two control groups(χ2 =0.193,P>0.05).Irrational chemotherapy, inappropriate usage and dosage and inappropriate indications were prominent problems in intervention group and advisory group.In addition,there were more improper solvent and contraindicated or adverse interaction problems in two control groups.Adverse events and incidence of unexpected events in intervention group (46.25%,12.50%) were significantly lower than those in two control groups[(73.75%,22.50%),(23.75%,18.75%)].Furthermore, the length of stay of intervention group patients was shortest in four groups (F=8.766,P<0.05).Conclusion By participating in the treatment group,clinical pharmacists can discover the irrational drug use and security risks in treatment,can provide medication guidance,consultation,publicity and other pharmaceutical service for specialist medical staff and patients.They will be more and more prominent in the treatment of cancer.
