Objective To observe the anticoagulant effect of low molecular weight heparin on induced hemodialysis in patients with acute renal failure.Method One hundred and eight patients with acute renal failure treated with induced hemodialysis were randomly divided into low molecular weight heparin(LMWH)group and unfractionated heparin(UFH)group.A bolus disc of UFH was given at first and then maintained by continuous infusion in UFH group,whereas a single bolus dose of LMWH with 2000AFXa IU to 4000AFXa IU in LMWH group.Results Anticoagulant effect between LMWH and UFH did not show significant discrepancy during induced hemodialysis.The bleeding from internal jugular vein catheter increased in the UFH group much more than that in the UFH group was significantly higher than that in the LMWH group.Anti-FXa blood levels were significantly higher in LMWH group than in UFH group.Conclusions LMWH has minor influence on aPTT and TT,while its anticoagulation effect approximates to that of UFH.LMWH represents a realistic alternative agent UFH in acute renal failure induced hemodialysis.

Objective:To investigate the characteristics and significance of insulin-like growth factor 1(IGF- 1) and insulin-like growth factor binding protein 2 (IGFBP2) expressions in ankle cartilage of patients with Kashin-Beck disease (KBD).Methods:In this case-control study, 10 KBD patients who were hospitalized in the Department of Orthopedics of Shaanxi Provincial People's Hospital from January 2010 to December 2016 were selected as KBD group, and 10 patients with ankle fracture caused by trauma but without talus injury during the same period were selected as control group, the cartilage tissues of the two groups were collected. IGF-1, IGFBP2 positive cells, the mRNA and protein expressions of IGF-1, IGFBP2 in the cartilage tissues were detected by immunohistochemistry, real-time fluorescent quantitative PCR and Western blotting, respectively. According to the expressions of IGF-1 and IGFBP2 in ankle cartilage of KBD patients, a patient with amputation caused by trauma was selected in Shaanxi Provincial People's Hospital, and ankle joint cartilage was taken to prepare chondrocytes for in vitro cell verification experiments. The chondrocyte were divided into control group (0 ng/ml T-2 toxin), T-2 treatment group (20 ng/ml T-2 toxin) and T-2+ IGFBP2 silenced group (20 ng/ml T-2 toxin+ 50 nmol/L IGFBP2 siRNA), the MTT method and dimethyl methylene blue staining were used to detect the activity of chondrocyte and the secretion of sulfated glycosaminoglycan (sGAG). Results:In the control group and the KBD group, the number of IGF-1[(47.26 ± 8.97), (68.15 ± 7.42) cells] and IGFBP2 positive cells [(27.56 ± 5.40), (71.85 ± 7.62) cells] in the cartilage tissues were significantly different ( t = 4.487, 9.402, P < 0.01). Compared with the control group, the IGF-1, IGFBP2 mRNA and protein expression levels in KBD group were significantly higher, the differences were significantly different ( t = 3.340, 20.700, 4.684, 8.699, P < 0.05 or < 0.01). In cell experiment, the chondrocyte activitives and sGAG contents of the control group, T-2 treatment group, and T-2+ IGFBP2 silenced group were significantly different ( F = 226.70, 80.66, P < 0.01); among them, the cell activitives and sGAG contents of the T-2 treatment group and T-2+ IGFBP2 silenced group were lower than those of control group ( P < 0.05), and the T-2+ IGFBP2 silenced group were higher than those of the T-2 treatment group ( P < 0.05). Conclusions:The expressions of IGF-1 and IGFBP2 in the ankle cartilage of KBD patients are significantly higher. Silencing IGFBP2 gene can reduce the inhibitory effect of T-2 toxin on chondrocyte activity and the secretion of sGAG.

Objective To analyse the high-dose dexamethasone suppression test(HDDST)-related differences in the clinical and biochemical features of the patients with Cushing's disease Methods Cases were drawn from 60 consecutive patients with Cushing's disease,who were then divided into two groups according to the response to the HDDST.The clinical and biochemical features between two groups were compared.Results(1) Of the 60 patients with Cushing's disease,23.3%(14/60)of patients(group A)did not yield results of suppression with the HDDST,and the others(group B)did.No difference was found in the age[(33.8?10.4 vs 36.2?11.2)years]and duration of illness[(2.1?1.6 vs 3.9?3.1)years]between two groups.(2)In clinical features,the patients in group A were more likely to have edema of lower limbs(64.3% vs 32.6%),hypokalemia (71.4% vs 28.3%),secondary diabetes(57.1% vs 26.1%)and purple striae(85.7% vs 54.3%,all P

Objective To explore the method of endovascular therapy for complicated aortic dissections.(Methods) The clinical data of 25 patients with complicated aortic dissections were analysed retrospectively.Results The patients′ ages ranged from 31-72 years with a mean of 50.2 years.Among the 25 cases,6 cases had severe ischemia of mesenteric artery,5 cases had renal artery ischemia,4 cases had severe(ischemia) of both legs,3 cases had renal arteries ischemia combined with superior mesenteric artery ischemia,2 had complicated aortic dissection combined with AAA,and in 5 cases the true aortic lumen was totally(compressed) by the false aneurysmal lumen.All patients underwent endovascular therapy,and the instant(technique) was successfully performed in all patients.Endoleak occurred in 3 cases after the stent-graft(deployment),it stopped spontaneously in 2 of them 7 days later,and 1 case with endoleak waiting for(treatment).In the other 22 patients,angiography after the operation showed that all the diseased area were sealed completely,and the viscera arterial blood supply was restored mainly via the true lumen.All the(patients) were cured and discharged.Conclusions In the management of complicated aortic dissections,(endoluminal) technique is simple,less traumatic,safe and has less complications as compared to the traditional operation.Improvement of the endoluminal technique is essential for successful treatment of these complicated cases.

In order to explore reasonable artificial cultivation pattern of Thesium chinense, the biological characteristics and nutrients change in the process of winter dormancy of T. chinense was studied. The phenological period of T. chinense was observed by using fixed-point notation and the starch grains changes were determined dynamically by PAS-vanadium iron hematoxylin staixjing method. Soluble sugar and starch content were measured by anthrone-sulfuric acid method and amylase activity was determined by DN'S method. The results showed that the normal life cycle of T. chinense was two years. T. chinense was growing by seed in the first year, but growing by the root neck bud in the second year. During the process of dormancy, starch and soluble sugar could mutual transformation in different periods. T. chinense had sufficient carbohydrate to maintain growth and also a lot of small molecules to improve their ability to fight against adversity.

Objective To investigate the effects of donor-specific regulatory T cells (Treg) transfusion on islet allograft survival. Methods Allogeneic fresh islets from Balb/c mice were transplanted to streptozotocin-induced diabetic C57 mice. The survival of islet allografts was observed. The experiment was divided into 3 groups: control group, nothing had been done to the recipients; simple islet transplantation group, the recipients received the islet transplantation only; experimental group, the recipients were given 1 ×106 Treg, then received islet transplantation. Results Blood glucose (BG) was above 16. 7 mmol/L after islet transplantation in control group; In simple islet transplantation group,BG level returned to normal level 1 to 2 days after transplantation, and hyperglycemia appeared 7 to 11 days after transplantation and maintained as the same as that before transplantation; In experimental group, BG level returned to normal level 2 days after transplantation and maintained at a low level,and at the 21st day after transplantation BG level was over 16. 7mmol/L in some recipients. Islet allograft survival in experimental group was significantly prolonged as compared with simple islet transplantation group. Conclusion Donor-specific Treg transfusion could prolong the islet allograft survival,and maybe have positive effect on tolerance induction of islet transplantation.
