Objective To compare the clinical efficacy of orthotopic ileal neobladder versus ortho- topic sigmoid neobladder.Methods The data of 96 patients who had undergone orthotopic ileal neoblad- der and 68 patients who had undergone orthotopic sigmoid neobladder were retrospectively analyzed.The perioperative condition,urinary continence,urodynamics,and pouch-related complications were compared between the 2 groups.Results Of all the 164 patients,12(7.3%)were lost to follow-up.The mean fol- low-up was 46(2-86)months in orthotopic ileal neobladder group,and 42(4-78)months in orthotopic sigmoid neobladder group.There was no significant difference in intraoperative blood loss and postoperative urinary continence between the 2 approaches(P＞0.05).However,compared with sigmoid neobladder group,ileal neobladder group had longer operative time and postoperative recovery time,and got a bigger pouch(P＜0.05).The early and late pouch-related complication rates of ileal neohladder group were 16. 7% and 29.2%,which were higher than those of sigmoid neobladder group.During the follow-up,tumor recurred in 3 cases of ileal neobladder group,but none in sigmoid neobladder group.Conclusions Ortho- topic ileal neobladder and sigmoid neobladder are similar in operative difficulties,and both can achieve satis- factory clinical results.Compared with ileal neobladder,sigmoid neobladder has shorter operative time, quicker recovery and lower rate of pouch-related complications,thus is a preferred procedure.

Background:From April to July in 2009 and 2010,unexplained severe hemorrhagic fever-like illnesses occurred in farmers from the Huaiyangshan mountains range.Methods:Clinical specimens (blood,urine,feces,and throat swabs) from suspected patients were obtained and stored.Mosquitoes and ticks in affected regions were collected.Virus was isolated from 2 patients and characterized by whole genome sequencing.Virus detection in additional patients and arthropods was done by virus-specific reverse transcription (RT) PCR.Clinical and epidemiological data of RT-PCR confirmed patients were analyzed.Results:An unknown virus was isolated from blood of two patients and from Haemaphysalis ticks collected from dogs.Whole genome sequence analysis identified the virus as a novel member of the family Bunyaviridae,most closely related to the viruses of the genus Phlebovirus within which it forms a separate lineage.Subsequently,infection was confirmed by RT-PCR in 33 of 58 suspected patients.The illness in these patients was characterized by fever,severe malaise,nausea,vomiting,and diarrhea.Prominent laboratory findings included low white cell- and platelet counts,coagulation disturbances,and elevation of liver enzymes.Hemorrhagic complications were observed in 3 cases,5 (15%) patients died.Conclusions:A novel tick-borne Bunyavirus causing life-threatening hemorrhagic fever in humans has emerged in the Huaiyangshan mountain areas of China.Further studies are needed to determine the epidemiology,geographic distribution and vertebrate animal ecology of this virus.

PURPOSE: Radioiodine (I-131) therapy is an effective modality to reduce both recurrence and mortality rates in differentiated thyroid cancer. Whether higher doses shows higher therapeutic responses was still debatable. The purpose of this study was to validate curve-fitting (CF) method measuring maximum permissible dose (MPD) by a biological dosimetry using metaphase analysis of peripheral blood lymphocytes. MATERIALS AND METHODS: Therapeutic effects of MPD was evaluated in 58 patients (49 females and 9 males, mean age 50+/-11 years) of papillary thyroid cancer. Among them 43 patients were treated with < or =7.4 GBq, while 15 patients with > or =9.25 GBq. The former was defined as low-dose group, and the latter high-dose group. Therapeutic response was defined as complete response when complete disappearance of lesions on follow-up I-131 scan and undetectable serum thyroglobulin levels were found. Statistical comparison between groups were done using chi-square test. P value less than 0.05 was regarded as statistically significant. RESULTS: MPD measured by CF method using tracer and therapeutic doses were 13.3+/-1.9 and 13.8+/-2.1 GBq, respectively (p=0.20). They showed a significant correlation (r=0.8, p< 0.0001). Exposed doses to blood measured by CF and biological methods were 1.54+/-0.03 and 1.78+/-0.03 Gy (p=0.01). They also showed a significant correlation (r=0.86, p=0.01). High-dose group showed a significantly higher rate of complete response (12/15, 80%) as compared to the low-dose group (22/43, 51.2%) (p=0.05). While occurrence of side effects was not different between two groups (40% vs. 30.2%, p=0.46). CONCLUSION: Measurement of MPD using CF method is reliable, and the high-dose I-131 therapy using MPD gains significantly higher therapeutic effects as compared with low-dose therapy.

BACKGROUNDLong-term maintenance of sinus rhythm after successful conversion of chronic atrial fibrillation (CAF), often ameliorates patients' symptoms, reduces the risk of ischemic stroke and improves cardiovascular hemodynamics. This prospective study aims to evaluate the long-term efficacy and safety of very low-dose amiodarone (100 mg daily) for the maintenance of sinus rhythm after successful direct-current (DC) cardioversion in patients with CAF and rheumatic heart disease (RHD) post intervention.

METHODSThis study was a randomized prospective trial. One day after successful DC cardioversion (remained normal sinus rhythm) in patients with CAF and RHD post intervention for more than six months and adequate anticoagulation, all were randomly administered either amiodarone 200 mg daily in group A or amiodarone 100 mg daily in group B.

RESULTSA total of 76 patients (40 men and 36 women) were examined from February 1998 to December 1999. The mean age of the patients was (66 +/- 10) years, and the mean follow-up was (67 +/- 8) months (range 61 to 84 months). Actuarial rates of the maintenance of sinus rhythm were similar in the two groups after 5 years of follow-up. Four patients (11%) in group A but none in group B experienced significant adverse effects that necessitated withdrawal of amiodarone. No death occurred during the study period.

CONCLUSIONA very low dose of amiodarone results in adequate long-term efficacy and is safe for maintaining sinus rhythm in patients with CAF and RHD post intervention after successful DC cardioversion.

The present study was designed to isolate and characterize novel chemical constituents of the stem bark of Juglans mandshurica Maxim. (Juglandaceae). The chemical constituents were isolated and purified by various chromatographic techniques. The structures of the compounds were elucidated on the basis of spectral data (1D and 2D NMR, HR-ESI-MS, CD, UV, and IR) and by the comparisons of spectroscopic data with the reported values in the literatures. Two long chain polyunsaturated fatty acids (1 and 2) were obtained and identified as (S)-(8E,10E)-12-hydroxy-7-oxo-8,10-octadecadienoic acid (1) and (S)-(8E, 10E)-12-hydroxy-7-oxo-8,10-octadecadienoic acid methyl ester (2). To the best of our knowledge, this is the first report on the isolation and structural elucidation of the two new conjugated ketonic fatty acids from this genus.
