BACKGROUND:The assessment for long-term efficacy of chronic ischemic disease is more important than the short-term efficacy assessment, which associates with patient’s long-term quality of life and long-term survival rate. OBJECTIVE:To observe the 5-year folow-up outcomes of autologous bone marrow stem cel transplantation for the treatment of thromboangitis obliterans. METHODS:This study enroled 43 patients of thromboangitis obliterans who underwent autologous bone marrow stem cel transplantation from August 2007 to January 2010 in the Department of Thyroid Vascular Surgery, the First Affiliated Hospital of Xinjiang Medical University. At 1, 2, 3, 4 and 5 years after transplantation, pain, cold sensation, and intermittent claudication distance were folowed up by telephone; changes in limb ulcers were observed. At 1 year after transplantation, venous oxygen partial pressure and oxygen saturation of limbs were reviewed. RESULTS AND CONCLUSION:A total of 38 thromboangitis obliterans patients with complete folow-up data were included in the final analysis. Compared to the preoperation, pain, cold sensation, and intermittent claudication significantly improved. The difference was statisticaly significant (Z values:-4.277,-5.086,-3.574, P < 0.001). Compared with 1-5 years after operation, pain and cold sensation had no statisticaly difference (P >0.05). Intermittent claudication distance had increased. Differences in terms of intermittent claudication distance was statisticaly significant (Z=43.898,P < 0.001). Significant differences in venous oxygen partial pressure and oxygen saturation were detected between preoperation and 1-year posttransplantation (tvalues: 36.790, 43.964,P values: 0.040, 0.037). Above results suggest that autologous bone marrow stem cel transplantation for thromboangitis obliterans obtained stable long-term outcomes.

Objective To investigate the changes of serum pituitary hormones and thyroid hormones in patients with severe brain injuries during hypothermia therapy. Methods Ninety-eight patients with severe brain injuries were randomly divided into mild hypothermia group (50 cases) and control group (routine therapy group,48 cases). The levels of serum PRL,TSH,FT 3 and FT 4 of patients in the both groups were detected by two-side sandwich immunological autochemoluminescence detection system before and after treatment. The therapeutic effects were observed and compared. Results After treatment,the levels of serum PRL,TSH and FT 4 of patients in hypothermia group were (0.25? 0.02) nmol/L ,(0.7?0.2) mU/L and (15.0?5.3) pmol/L,respectively,which were significantly lower than that in control group,ie,(0.46?0.04) nmol/L,(1.1?0.3) mU/L and (21.2? 6.4) pmol/L ,respectively. The good recovery rate (62%) in hypothermia group was higher than that of control group (35%) but the death rate (22%) in hypothermia group was lower than that of control group (42%). Conclusions Mild hypothermia can inhibit the rise of serum pituitary hormones and thyroid hormones after severe brain injury and improve the therapeutic effects.

BACKGROUND:With the development of surgical techniques and endovascular treatment techniques, the therapeutic efficacy on arteriosclerosis obliterans of the lower limbs has been improved greatly. As the long-term prognosis is stil not clear, how to treat arteriosclerosis obliterans of the lower limbs is stil a problem for vascular surgery. OBJECTIVE:To observe the long-term clinical efficacy of autologous bone marrow stem cel transplantation in the treatment of arteriosclerosis obliterans of the lower limbs. METHODS:Thirty-nine patients with arteriosclerosis obliterans who had undergone autologous bone marrow mesenchymal stem cels (totaly 56 times of cel transplantation) from September 2007 to July 2013 were enroled in this study. As of February 2015, the folow-up time was 7.5 years. After treatment, regular telephone folow-up about limb pain, cold sensation, intermittent claudication distance, resting ankle-brachial index and limb ulcer size and depth was done annualy; at 1 year after treatment, limb arteriography and venous blood gas analysis were reviewed. RESULTS AND CONCLUSION: Of the enroled 39 patients, 4 patients were subjected to amputation because of poor efficacy, 2 patients died of acute myocardial infarction, and 2 patients died of not timely amputation. There were 31 patients who had been folowed up for over 3 years. After treatment, the resting ankle-brachial index and limb ulcer size and depth limb pain were both improved significantly. There were significant differences in 1-year limb blood oxygen partial pressure and oxygen saturation before and after treatment, and the postoperative number of capilaries also increased significantly. These findings indicate that autologous bone marrow stem cel transplantation is a safe treatment for arteriosclerosis obliterans of the lower limbs with better and stable long-term curative effects. This method is a good choice for patients who have poor blood vessels and poor efficacy of traditional methods.
