OBJECTIVETo evaluate the clinical efficacy of ultrasound-guided lauromacrogol sclerotherapy for benign thyroid cysts and analyze the factors affecting the efficacy.

METHODSUltrasound-guided lauromacrogol sclerotherapy was performed in 97 patients with a total of 99 benign thyroid cysts. The changes in cystic volume and other thyroid parameters were evaluated at 1, 3, 6, and 12 months after sclerotherapy. According to changes in the cystic volume, the efficacy of sclerotherapy was defined as therapeutic failure (with a volume reduction <50%), treatment success (volume reduction ≥50%) and cure (volume reduction ≥90%). The factors of affecting the efficacy of sclerotherapy was analyzed using COX regression.

RESULTSThe mean cystic volume at 1, 3, 6 and 12 months after sclerotherapy were reduced from the baseline volume of 12.08∓11.56 cmto 5.63∓8.51 cm, 5.96∓8.42 cm, 3.80∓5.50 cmand 2.85∓3.98 cm, respectively, with an average cystic volume reduction rate of (70.02∓33.72)%. Therapeutic success was achieved 82 of the 99 cysts (82.83%) and cure was achieved 63cysts (63.64%) at 12 months after the procedure. A second sclerotherapy was performed for 13 cysts which did not show a volume reduction at 1-3 months after the initial procedure. A disease course of over 12 months was an independent risk factor for a second sclerotherapy (23.7% [9/38] vs 6.6% [4/61], OR=4.473 [1.238-16.169], P=0.022). The efficacy of sclerotherapy was related to cystic cavity separation, cystic fluid viscosity, cystic/solid ratio and cystic wall thickness. COX regression analysis revealed that cystic cavity separation (HR=2.25, 95%CI: 1.19-4.25) and cystic fluid viscosity (HR=2.02, 95%CI: 1.19-3.43) were the major factors affecting the treatment efficacy.

CONCLUSIONUltrasound-guided lauromacrogol sclerotherapy is effective and safe for treatment of benign thyroid cysts, and the maximal treatment effect can be achieved at 6 months after sclerotherapy and in cases of uncomplicated cysts with non-viscous cystic fluid, no solid cystic cavity separation and a disease course of less than 12 months.

OBJECTIVETo assess the value of the model for end-stage liver disease (MELD) in predicting the early-stage outcome of liver transplantation in patients with end-stage liver disease.

METHODSThe MELD scores of 87 liver transplantation recipients with end-stage liver disease were calculated, and their early-stage complications and mortality were analyzed.

RESULTSThe incidence of severe complications was 20.7%; in these recipients, with the 28-day and 3-month survival rates of 89.7%; and 88.5%;, respectively. The mean MELD scores showed significant differences between the complication-free group and survival group (14.6 vs 12.9, P<0.05), and also between the complication group and death group (21.6 vs 29.4, P<0.05). Compared to patients with MELD no greater than 15, patients with MELD between 16 and 24 showed significantly increased complication rate but had comparable survival rate (P>0.05); but in patients with MELD no less than 25, the survival rate was significantly decreased with also increased complication rate.

CONCLUSIONSA higher MELD score before liver transplantation is associated with greater likeliness of early-stage complication rate and mortality. High MELD score (over 25) can be a useful index in predicting severe complications and death in patients undergoing liver transplantation.

OBJECTIVETo investigate the correlation between liver and skeletal muscle fat contents and insulin resistance in obese individuals with different levels of glucose tolerance.

METHODSRESULTS: Ten non-obese individuals with normal glucose tolerance (NGT), 9 obese individuals with NGT, and 7 obese individuals with impaired glucose tolerance (IGT) were enrolled in this study. All the participants were examined for insulin sensitivity by hyperinsulinemic-euglycemic clamp and for liver and skeletal muscle fat accumulation quantified by proton magnetic resonance spectroscopy (1H MRS). The data were collected from the subjects including somatometric measurements, fasting plasma glucose, 2-h plasma glucose (2hPG), fasting insulin, and blood biochemistry. Linear correlation analysis and multiple linear stepwise regression analysis were used to analyze the relationship between ectopic fat accumulation and insulin resistance.

RESULTSThe glucose infusion rates (GIR, presented as the M value) differed significantly among IGT-obese (3.95∓1.66 mg·kg·min), NGT-obese (6.14∓1.90 mg·kg·min) and NGT-non-obese (8.78∓2.46 mg·kg·min) groups (P<0.05). The 3 groups also showed significant differences in liver fat contents [(15.23∓3.09)%, (6.25∓0.38)%, and (1.89∓0.90)%, respectively, P<0.05] and intramyocellular lipids in the tibialis anterior (2.69∓0.95, 2.61∓1.45, and 1.54∓0.66 mmol/kg, respectively, P<0.05). Linear analysis revealed that liver fat content, but not skeletal muscle fat content, was significantly correlated with the M value. Multiple linear stepwise regression analysis using M value as the dependent variable (Y) revealed that liver fat content (X) was an independent factor inversely correlated with the M value (regression equation: Y=-30.562X+9.007, R=0.717, P<0.01).

CONCLUSIONSLiver fat accumulation, but not skeletal muscle fat accumulation, is correlated with insulin resistance and impaired glucose metabolism.

OBJECTIVE: To find out the mortality trend and related factors in aged hospitalized patients with diabetes mellitus(DM). METHODS: The case information diabetic in patients who died during the period from 2005 to 2014 were collected and the mortality and causes of death were analyzed. RESULTS: From 2005 to 2014, 1297 diabetic patients died, and the mortality of elderly DM inpatients was 4.44%(1162 cases), significantly higher than that of the non-elderly of 0.94%(P<0.001). The death rate of elderly diabetic patients was significantly higher in males than in females(5.22% vs. 3.47%, P<0.001). The mortality of the aged diabetic patients decreased within 10 years(P<0.001), decreasing from 4.75% in 2005 to 3.01% in 2009(P<0.001) in the year of 2005-2009, while there were no differences in the year of 2010-2014. The main death causes of the aged diabetic in-patients were as follows: infections(27.71%), cardiovascular diseases(25.22%), tumor(21.34%), cerebral vascular diseases(10.41%) and diabetic complications(5.51%). The first death cause in the 60-79 yrs group was cardiovascular diseases, while in the ≥80 yrs group, it was infections. The constituent ratio of infection as death cause in the aged during 2010-2014 significantly increased(22.60% vs. 32.50%, P<0.001), increasing by 43.81%, and it became the first cause of death in 2010. CONCLUSION: The death rate of the elderly DM in-patients has decreased significantly within 10 years, from 2005 to 2014, while the rate has kept steady from 2010. Infections and cardiovascular diseases are the main cause of death. So it's important to prevent the elderly hospitalized DM patients from infection, in addition to cardiovascular diseases, and to control in time.
