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.

ConclusionThe pharmacokinetics of rats ks fit to one-compartment model.

Objective To investigate the expression of Oct-4 as a stem cell marker in gastric carcinoma tissues and its clinical significance. Methods From June 1996 to March 2006, 63 paraffin samples of gastric carcinoma tissues were obtained, and the expression of Oct-4 was examined by immunohistochemical staining. Another 58 normal tissues adjacent to gastric carcinoma and 10 normal gastric mucosa tissues were served as controls. The clinieopathologieal data of 63 patients with gastric carcinoma were retrospectively analysed, and their relationship with the expression of Oct-4 was analysed. Fifty of these 63 patients were followed up for 8 years, Kaplan-Meier method and Log-rank teat were employed to explore the correlation between Oct-4 expression and survival, and Cox Regression analysis was performed to evaluate the possibility of Oct-4 expression as an independent prognostic factor for gastric carcinoma. Results The positive expression rate of Oct-4 in gastric carcinoma tissues was 80.95% (51/63), significantly higher than that of normal tissues adjacent to gastric carcinoma (5.2%, 3/58) and normal gastric mucosa tissues (0) (P < 0.01). The expression of Oct-4 was positively correlated to the clinical stage of gastric carcinoma(P<0.01). There was no significant difference in the expression of Oct-4 among patients with different differentiation, age, and gender (P>0.05). Patients with higher expression of Oct-4 had significantly shorter survival time (P<0.05). The expression of Oct-4 was not significantly correlated with the prognosis of gastric carcinoma(RR, 0.554; 95% CI, 0.209-1.466). Conclusion The expression of Oct-4 is correlated with the clinical stage and survival time of patients with gastric carcinoma, however, it is not an independent prognostic factor for gastric carcinoma.

OBJECTIVETo study clinical results of reduction and fixation under arthroscopy for the treatment of osteochondrotical lesion in the knee.

METHODSFrom December 2012 to December 2013, 4 patients with the knee joint osteochondritis lesion and free bone fragments were treated with arthroscopy to detect the stripped cartilage, and then the cartilages were reduced with small incision and fixed by cartilage nail. There were 3 males and 1 female, with age of 15, 15, 20 and 27 years old. The durations of the disease were 1 d, 5 d, 1 month and 1 year. All the patients had swelling and effusion in the knee joint, and the floating patellar test was positive. CT examination showed bone defects and loose bodies. The Lysholm, VAS, and Tegner scale were used to evaluate the knee joint functions before and after operation.

RESULTSAll the patients underwent successful surgery. Postoperative CT showed good location of the cartilage without loss of reduced bone and cartilage. All the patients were followed up, and the duration ranged from 10 to 13 months, with a mean of 12 months. In one patient, arthroscopy examination was conducted for a second time to examine the connection of the fracture part to the surrounding cartilage, and it showed that the internal fixator was not absorbed. The Lysholm, VAS and Tegner scale of all patients were better than those before operation.

CONCLUSIONTreatment of osteochondritis lesion with the fixation of absorbable cartilage nails may reconstruct the integrity of articular surface and recover the stability of joints, and it is an effective treatment method.

[Summary] According to the cutpoint of plasma triglycerides concentration ≥ 1.7 mmol/L,waist circumference ≥85 cm in men or ≥80 cm in women,459 patiens with type 2 diabetes mellitus were divided into four groups:normal waist circumference and triglycerides,normal waist circumference and hypertriglyceridemia,abdominal obesity and normal triglycerides,and hypertriglyceridemic-waist (HTWC) group.The results showed that body mass index,waist circumference,systolic blood pressure,triglycerides,microalbuminuria,and homeostasis model assessment insulin resistance index (HOMA-IR) in HTWC group were higher than those in non-HTWC groups (all P＜0.01),as well as higher diabetic nephropathy incidence (P＜0.05).Multiple logistic regression analysis revealed that HTWC was an independent risk factor of diabetic nephropathy (OR =2.070,95 ％ CI 1.195-3.586).

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.

To study the regulation of androgen receptor (AR) expression in human prostate cancer LNCaP cells by triptolide (TP) and the possible mechanism, by using qRT-PCR and Western blot, the AR mRNA and protein levels in TP treated LNCaP cells were detected, and the AR protein level in TP and NF-κB inhibitor treated LNCaP cells was also detected; a series of pGL3-AR promoter reporter gene vectors were built using restriction-free cloning method, and the vectors were employed to investigate the effects of TP on the transcriptional activity of AR promoter in LNCaP cells; the upstream proteins which may play regulatory roles were detected using western blot assay. After treated LNCaP cells with TP for 48 h, AR mRNA and protein expressions decreased with increasing TP concentration. The expression of AR target gene PART1 and prostate specific antigen (PSA) was also downregulated by TP treatment; a series of pGL3-AR promoter reporter vectors were constructed and validated by sequencing and luciferase activity; the results of dual luciferase reporter assay showed that TP downregulated AR at the transcriptional level; PI3K/AKT/NF-κB pathway which is associated with AR promoter activity was drowregulated by TP. In conclusion, our results demonstrated that the transcriptional activity of AR in LNCAP cells was downregulated by TP, and PI3K/AKT/NF-κB pathway may be involved in the regulation mechanism.
