Objective To explore the feasibility and effect of intervention therapy for patients subclavian steal syndrome.MethodsThe data of 35 patients with subclavian artery steal syndrome in neurology department of our hospital from October 2014 to March 2016 were retrospectively analyzed.All patients treated with pecutaneous transtuminl angioplasty and stenting.The degree of vascular stenosis was measured by digital subtraction angiography, the inter-arm blood pressure was tested by mercury sphygmomanometer.And the clinical manifestations before and after surgery were compared.All patients were followed up for 1 to 12 months,the clinical manifestations,blood flow and vascular stenosis degree in patients were observed.Results All patients were finished pecutaneous transtuminl angioplasty and stenting successfully,7 patients with serious vascular stenosis treated with percutaneous intravascular balloon dilatation at first.The average artery stenosis before operation was(74.73±10.42)%,while it decreased to(8.60+3.16)% after surgery,which were measured by DSA,the difference was significant(P<0.01).The result from mercury sphygmomanometer showed that the inter-arm blood pressure from preoperative(44.43±10.12)mmHg to postoperative (10.09+4.80)mmHg (2~7 days),systolic blood pressure differential minified significantly,the difference was significant(P<0.01).All patients were followed up for 1 to 12 months,support forms of 34 cases were in good conditions without new narrow,1 case appeared narrow in postoperative 7 months,then recovered after reoperation;symptoms of 28 cases significantly improved or disappeared,5 cases partly alleviated,2 cases had recurrence,no serious complications such as thrombosis and severe infarction occurred.Conclusion The pecutaneous transtuminl angioplasty and stenting is stable,high successful and low short-term recurrence rate for subclavian steal syndrome,which is good to alleviate vascular stenosis,reduce interrm blood pressure difference and improve clinical manifestation.

Background Nowadays,glaucoma is the major cause of irreversible blindness worldwide and the second cause of global visual loss.To accurately obtain the anterior chamber depth (ACD)is of helpful for screening primary angle-closure glaucoma (PACG).ObjectiveThe aim of this study is to explore the difference and agreement in the measurement of ACD between Scheimplug Imaging System (Pentacam)and ultra-sonographic biomicroscope (UBM).MethodsSeventy-seven eyes of 77 PACG patients aged (69.96±7.87)were divided into two groups.Thirty-seven eyes with acute primary angle-closure glaucoma (APACG)were assigned to group 1,and forty eyes with chronic primary angle-closure glaucoma (CPACG)were assigned to group 2.Central ACD was measured with Pentacam and UBM,respectively.The Bland-Altman method was used to evaluate the agreement of the two methods.ResultsThe ACD values measured by Pentacam and UBM were (1.6467±0.2687)mm and (1.5601±0.2677)mm respectively in APACG,indicating a significant difference (t=-7.259,P<0.01)and a positive linear correlation between the results of these two methods (r=0.939,P<0.01).The ACD values measured by Pentacam and UBM were (2.0622±0.2317)mm and (1.9648±0.2176)mm respectively in CPACG eyes with a significant difference between them(t=-10.433,P<0.01)and a significant linear correlation between these two outcomes (r=0.967,P<0.01).The Bland-Altman method showed that the two modalities had comparable results for ACD.ConclusionPentacam,as a new 3-dimensional mathematical model of the anterior segment,presents some different results from UBM in the measurement of ACD,but it is not clinically significant.Combination of Pentacam and UBM may be available for the clinical measurement of ACD.

Objective To prepare transferring and R8 co-modified liposome (TF/R8-LP)for forhepatoma targeting.Methods The co-modified liposome were prepared by film-ultrasonic method.The appearance,particle size,Zeta potential were evaluated.The cellular uptake by HepG2 cell in vitro was used to evaluate the targeting efficiency and in vivo imaging were used to evaluate the targeting efficiency. Results The particle diameter of the co-modified liposome was(108.5 ±12.6)nm and the Zeta potential was(24.15 ±4.78)mV.The liposome kept stable in 50% FBS at 24 h.The result demonstrated that the co-modified liposome uptaken by HepG2 were 2.4,2.6 times higher than that of R8-LP and TF-LP,respectively(P<0.05).The evaluation of tumor spheroid penetration and in vivo imaging results showed the co-modified liposome had the strongest fluorescence intensity. Conclusion The co-modified liposome might serve as a promising hepatoma delivery system of antitumor drugs.

To study the function of lipoprotein lipase (LPL)with Asn291 Ser and Lys312insC compound mutation in LPL gene knockout heterozygous (LPL~(+/-)) mice. The results showed that triglycerides, free fatty acids, blood glucose and weight of LPL~(+/-) mice were higher than those of c57 mice(P<0. 05). The expressions of LPL Mrna and LPL protein of LPL~(+/-) group were lower than those of c57 group(P<0.05). The injection of Asn291Ser +Lys312insC protein caused little change of the lipid mass and LPL activity,but the injection of normal LPL protein induced obvious decrease of lipid mass and increase of the LPL activity.

Objective Monitoring the thyroid hormone levels in patients before and after renal transplantation to realize the relationship between thyroid hormones and renal function.Methods Fifty-seven patients were subdivided into stabled graft function group (50 cases) and delayed graft function (DGF) group (7 cases).Thirty healthy men served as control group.Serum triiodothyronine (T3),thyroxine (T4),thyroid-stimulating hormone (TSH) and serum creatinine (Scr) were determined respectably before transplantation and on different days after transplantation.Correlations between thyroid hormones and Scr at 10th day after transplantation were analyzed.Results Serum T3 and T4 levels before transplantation in the two groups were significantly lower than those in the control group (P＜0.01).These four parameters levels had no significant difference between stabled graft function group and DGF group (P＞0.05).In stabled graft function group:T3 level was decreased obviously by 30％ in the 1st day after transplantation,which was higher than the others,elevated at the 1st week post-transplantation,reached the normal range.at the 2nd week post-operation,and higher than pre-transplantation (P ＜ 0.01) at 3rd week; T4 revealed a decrease trend after transplantation and was elevated at 10th day post-transplantation,returned to the pre-transplantation level at 3rd week; TSH had slight decrease after operation,and had no significant difference among every period in comparing with pre-transplantation; Scr revealed a decrease trend continuously and returned to the normal level at the 7th day post-transplantation.In DGF group,Hormones levels were obviously decreased as compared with stabled graft function group; T3 reached the normal range at the 3rd week post-transplantation,whereas T4 returned to pre-transplantation levels at the 30th day; TSH had a significant decrease at the 5th day,and began to increase at the 10th day post-operation; Scr retuned to the normal range at the 30th day post-operation.The correlation coefficients between Scr and T3,T4 were 0.546 and 0.423 respectively.Conclusion There is a significant correlation between thyroid hormones and renal function (T3,T4).Monitoring the thyroid hormones,specially T3,can diagnose renal function change.

Objective To evaluate different measurement methods in histogram for the diffusion and perfusion parameters from intravoxel incoherent motion (IVIM) MR imaging of different types of uterine fibroids.Methods 63 patients with confirmed uterine fibroids (80 in total) were examined with MR imaging.3D T2WI and IVIM imaging were performed for those patients.The fibroids were classified into three types (type 1, 2, 3) on the basis of different signal intensities on T2WI according to Funaki's theory.Real diffusion coefficient (D), pseudodiffusion coefficient (D*) and perfusion fraction (f) were calculated using IVIM analysis.25%,50% and 75% of those parameters (D25,D50,D75,D*25,D*50,D*75,f25,f50 and f75) as well as mean values (Dmean,D*mean and fmean) were calculated using histogram method.ANOVA was used to compare the IVIM parameters among the three types of fibroids.Results There were 44 type 1,24 type 2 and 12 type 3 fibroids in the total of 80 fibroids.There was significant difference among all the diffusion parameters from histogram and mean values of different types of fibroids, and only one perfusion parameter D*75 value showed significant difference (P<0.05).There was no significant difference among all the f values from histogram and mean values.Conclusion Different measurements of parameters from IVIM histogram showed no added value for diffusion features in different types of fibroids compared to mean value.While the perfusion parameter D*75 value from histogram can distinguish the features of perfusion within different types of fibroids compared to mean value.
