AIM To examine the medical status of children with biliary atresia(BA) surviving with native *** In this cross-sectional review,data collected included complications of chronic liver disease(CLD)(cholangitis in the preceding 12 mo,portal hypertension,variceal bleeding,fractures,hepatopulmonary syndrome,portopulmonary hypertension) and laboratory indices(white cell and platelet counts,total bilirubin,albumin,international normalized ratio,alanine aminotransferase,aspartate aminotransferase,γ-glutamyl transpeptidase). Ideal medical outcome was defined as absence of clinical evidence of CLD or abnormal laboratory indices. RESULTS Fifty-two children [females = 32,62%; median age 7.4 years,n = 35(67%) older than 5 years] with BA(median age at surgery 60 d,range of 30 to 148 d) survived with native liver. Common complications of CLD noted were portal hypertension(40%,n = 21; 2 younger than 5 years),cholangitis(36%) and bleeding varices(25%,n = 13; 1 younger than 5 years). Fifteen(29%) had no clinical complications of CLD and three(6%) had normal laboratory indices. Ideal medical outcome was only seen in 1 patient(2%). CONCLUSION Clinical or laboratory evidence of CLD are present in 98% of children with BA living with native livers after hepatoportoenterostomy. Portal hypertension and variceal bleeding may be seen in children younger than 5 years of age,underscoring the importance of medical surveillance for complications of BA starting at a young age.

AIM To study implications of measuring quality indicators on training and trainees' performance in pediatric colonoscopy in a low-volume training *** We reviewed retrospectively the performance of pediatric colonoscopies in a training center in Malaysia over 5 years(January 2010-December 2015), benchmarked against five quality indicators: appropriateness of indications, bowel preparations, cecum and ileal examination rates, and complications. The European Society of Gastrointestinal Endoscopy guideline for pediatric endoscopy and North American Society for Pediatric Gastroenterology, Hepatology and Nutrition training guidelines were used as *** Median(± SD) age of 121 children [males = 74(61.2%)] who had 177 colonoscopies was 7.0(± 4.6) years. On average, 30 colonoscopies were performed each year(range: 19-58). Except for investigations of abdominal pain(21/177, 17%), indications for colonoscopies were appropriate in the remaining 83%. Bowel preparation was good in 87%. One patient(0.6%) with severe Crohn's disease had bowel perforation. Cecum examination and ileal intubation rate was 95% and 68.1%. Ileal intubation rate was significantly higher in diagnosing or assessing inflammatory bowel disease(IBD) than non-IBD(72.9% vs 50.0%; P = 0.016). Performance of four trainees was consistent throughout the study period. Average cecum and ileal examination rate among trainees were 97% and 77%.CONCLUSION Benchmarking against established guidelines helps units with a low-volume of colonoscopies to identify area for further improvement.

Dengue Vaccines: Challenge and Confrontation

World Journal of Vaccines 2011年第4期1卷 109-130页

作者： Guey Chuen Perng Huan-Yao Lei yee-shin Lin Kulkanya Chokephaibulkit 不详

Dengue has been recognized as one of the most important vector-borne human diseases. The disease is induced by dengue virus infection resulting from the bite of an infected Aedes spp. mosquito after imbibing the tainted blood from animals or patients. Dynamic clinical spectrums ranging from asymptomatic, undifferentiated fever, typical dengue fever (DF), dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) have been well documented. Initially, the disease was mainly restricted in tropical and subtropical zones. However, with factors such as ineffective vector control, frequency of human migration, unplanned urbanization, and changing climate temperature, the disease has been spotted at almost every territory of the earth. Dengue has been associated with human disease for more than two centuries. Although classic DF is viewed as a self-limited illness, subjects normally resolve within two weeks and recover without any noticeable complications or sequelae, some of these infected individuals may progress to life-threatening DHF/DSS, characterized with plasma leakage due to an increase in capillary permeability. The significantly increased public health threat and the burden of morbidity and mortality of dengue globally has caught the attention of public officials and prompted an action to find a way to contain and prevent the disease. The lack of specific dengue therapeutics has led to an emphasis on vaccine development, one of the best and effective strategies to reduce and prevent the illness. Making a dengue vaccine has been attempted more than six decades;although some of these products are in clinical trials, vaccine development for the prevention of dengue disease is still at its infancy. So far no dengue vaccine is available for the public. Dengue vaccine development may be hindered by the complexity of the clinical presentations, which implicates that multiple pathogenic mechanisms are involved in dengue disease. Some of these elements will be discuss

Structure and Photoluminescence Properties of Pr3+Ion-Doped BaY2ZnO5Phosphor Prepared Using a Sol-Gel Method?

引用

Journal of Modern Physics 2019年第2期10卷 91-101页

作者： Hung-Rung Shih Mu-Tsun Tsai Lay-Gaik Teoh yee-shin Chang Department of Mechanical and Computer-Aided Engineering National Formosa University Taiwan Department of Materials Science and Engineering National Formosa University Taiwan Department of Mechanical Engineering National Pingtung University of Science and Technology Taiwan Department of Electronic Engineering National Formosa University Taiwan

The Pr3+ ion-doped BaY2ZnO5 phosphor with the orthorhombic structure was synthesized successfully using a sol-gel method in this study. The SEM images show that the BaY2ZnO5:Pr3+ phosphor particles are aggregational but have an isotropic distribution for 2 mol% Pr3+ ions doped. Under an excitation wavelength of 311 nm, the emission bands that appear in the emission spectra are due to the 3P0→3H4,5,6, 1D2→3H4 and 3P0→3F2 electron transition of Pr3+ ion, and it is the same as that for solid state reaction preparation. Comparing to the solid state reaction preparation, the intensities of the 3P0→3H4 transition were increased by about 6.5 times for sol-gel method. The enhancement in emission intensity is because the activators have more homogeneous contribution in host for the sol-gel method preparation. In addition, the color tone did not change very obviously, which located around the green light region for Pr3+ ion concentrations increasing. The color stability is better for sol-gel method than that for the solid state reaction preparation.

Dominance of Brassica and No Effects of Raphanus in Mature Seed Production in Intergeneric Hybrid between Brassica rapa ssp. Pekinensis and Raphanus

引用

American Journal of Plant Sciences 2022年第3期13卷 416-432页

作者： Soo-Seong Lee Cho yee Son Eunsil Kim Hosub shin Jeong Eun Park Seung Hwa Yu Jin Hoe Huh BioBreeding Institute Anseong Gyeonggi South Korea Department of Agriculture Forestry and Bioresources College of Agriculture & Life Science Seoul National University Seoul South Korea

We succeeded in producing mature seed from a line of Brassica rapa ssp. pekinensis that had been hybridized with Raphanus sativus var. major. Our focus was on dominance of B. rapa ssp. pekinensis;radish (R. sativus var. major) had no influence. Marker tests for similarity showed that the original CR291M-64 x HwiM-2 hybrid was an inbred CR291M-64, rather than a genuine cross;this appears to have resulted from weak self-incompatibility in this strain. The plants from the mature seed bloomed with reddish flowers differently shown up to present. The intergeneric hybrid between Brassica inbred and Raphanus hybrid was very weak in strength compared to the Brassica inbred which was self-pollinated even though the cause of the weak was not identified. The hybrids between Brassica hybrid, dominant and elite recessive, and Raphanus can be developed in large quantities using mature hybrid seed without resorting to ovule culture techniques.
