Objective To validate the theraputic efficacy of percutaneous ethanol injection(PEI) for hyperparathyroidism caused by parathyroid adenoma.Methods One case of parathyroid adenoma underwent PEI whose diagnosis was comfirmed by biopsy. The 22 gauge needle was punctured into the adenoma under CT guidance and ethanol was injected into the lesion at multiple points. Results The CT images obtained 6 months after 2 times of CT guided PEI revealed that the volume of the adenoma decreased markedly together obviously with decrease of enhancement after the injection of contrast media. The level of serum parathyroid hormone, calcium and phosphorous returned normal 2 days to 12 months after the management. The clinical manifestations improved markedly.Conclusions CT guided PEI is a minimally invasive and highly effective theraputic modality for hyperparathyroidism. It can serve as an important supplement to surgery.

Objective To investigate the influence of FTY720 on the lymphocytes and their recovery after withdrawal of FTY720,and on the changes in T cell subsets of inbred mice so as to direct the administration of FTY720. Methods Male inbred C57/bl mice were given FTY720 at the dose of 3 mg/kg per day by oral gavage once a day for 14 days. The PBLs were counted and T cell subsets were analyzed by flow cytometry at the selected time points. Results When FTY720 was administrated, the PBLs showed a sharp decrease and reached the minimum 4 hours later.Then the PBLs remained stable during the whole pe- riod of administration.The PBLs didn’t restore immediately when the reagent was withdrawn,but increased slowly 2 weeks later and completely recovered 6 weeks later.The changes of T cells were similar to PBLs.CD - 8 subsets showed relatively higher sensitivity to FTY720. Conclusions FTY720 is a safe reagent which has rapid and specific effects on PBLs,and the changes in PBLs are reversible.The effect of FTY720 on T cell subsets is similar to that on PBLs.CD - 8 T cells are relatively more sensitive to FTY720.

Objective To investigate the significance of the changes in heart rate variability (HRV) in patients undergoing coronary artery bypass graft procedure Methods Thirty six patients scheduled for elective coronary artery bypass were studied HRV was monitored by HXD I monitoring system one day prior to surgery (as baseline values), before anesthesia, at the end of surgery and on the 3rd day and 6th day after surgery Results The baseline logical values for total power(TP), low frequency (LF), high frequency (HF), LF/HF ratio were 3 07?0 35, 2 38?0 47, 2 37?0 54 and 1 34?0 93 respectively There were no significant changes in all these parameters before anesthesia as compared to baseline values LF,HF and TP decreased significantly on the 3rd day after surgery as compared with baseline values, and were kept at the level on the 6th postoperative day Conclusions The decrease in HRV power can last over 6 days after coronary bypass graft surgery, signifying reduced autonomous regulation of heart in the early postoperative days

Objective To explore the effect evaluation of choking risk assessment and intervention on the choking prevention of homeless inpatients with psychiatricc. Methods Totally 163 homeless inpatients with psychiatric disorder were selected from July 2012 to June 2016, 56 cases from July 2012 to December 2013 were assigned to the control group, another 107 cases from January 2014 to June 2016 was set as the intervention group. The control group received routine nursing safety management, on the basis of it, the intervention group received choking risk assessment through choking risk assessment scales. To take choking risk intervention on the patients of reached choking danger threshold. The incidence of choking and choking ending were compared between the two groups and the choking risk levels and scores in the intervention group before and after intervention were also compared. Results The incidence of choking in the intervention group and the control group was 0.93%(1/107)and 10.71%(6/56)respectively. Choking ending: 2 heal, 3 aspiration pneumonia, 1 death of 6 cases in the control group and 1 case was cured, no death and aspiration pneumonia occurred in the intervention group, the statistical differences were significant (χ2=9.399,18.554, P < 0.01 or 0.05). There were 28.0% (30/107) reached level Ⅰ, Ⅱ and Ⅲ choking threshold in the intervention group and rank mean of choking risk scores were 41.29. After interventions were 8.4% (9/107) and 25.50 respectively, the statistical differences were significant (χ2=10.231, P<0.05;Z=7.511, P<0.01). Conclusions The corresponding nursing intervention on the patients of choking risk can reduce and avoid choking accidents and protect the safety of homeless inpatients with psychiatric disorder effectively and improve the quality of care.
