AIM： To correlate the clinical features of treated and untreated patients with irritable bowel syndrome （IBS） to the results of skin prick test （SPT） for food and inhalant allergens. METHODS： We recruited 105 subjects to form three different target groups： treated group （n=44） undergoing treatment for IBS, untreated group （n =31） meeting the Rome Ⅱ criteria without treatment for IBS, control group （n = 30） with no IBS symptoms. RESULTS： SPT results were different among the three groups in which SPT was positive in 17 （38.6%） treated patients, in 5 （16.1%） untreated patients and in 1 （3.3%） control （P〈0.01）. The number of positive SPTs was greater in the IBS group than in the control group （P〈 0.001）. The number of positive food SPTs was higher in the treated IBS group than in the untreated IBS group （P= 0.03）. CONCLUSION： Positive food SPT is higher in IBS patients than in controls.

World Journal of Gastroenterology 2007年第11期13卷 1646-1651页

AIM： TO examine the diagnostic yield of colorectal neoplasia at computed tomographic colonoscopy （CTC） as well as the feasibility of contrast enhanced CTC in patients with gastric cancer. METHODS： To examine the incidence of colon polyp we selected postoperative 188 gastric cancer patients, which we refer to as the ‘colon polyp survey group’. To examine the feasibility of CTC for early detection of colon cancer or advanced colon adenoma, we selected 47 gastric cancer patients （M：F 29：18, mean age 53.8 years）, which we call the ‘CT colonoscopy group’. All the 47 patients underwent successive CTC and colonoscopy on the same day. RESULTS： Totally 109 colon polyps were observed from 59 out of 188 gastric cancer patients, the inddence rate of colon polyps in gastric cancer patients being 31.4%. The sensitivity of CTC in detecting individuals with at least 1 lesion of any size was 57.1%, the specificity was 72.7%, the positive predictive value was 47.1%, and the negative predictive value was 71.9%. When the cutoff size was decreased to 6 mm, the sensitivity and specificity were 80.0% and 92.9%, respectively, with positive and negative predictive values of 57.1% and 97.5%, respectively. Only one patient was classified as false negative by virtual colonoscopy. CONCLUSION： The diagnostic yield of colorectal polyp was 31.4% in patients with gastric cancer, and contrast enhanced CTC is an acceptable tool for the detection of synchronous colorectal advanced adenoma and postoperative surveillance of gastric cancer patients.

Chest wall metastasis from unknown primary site of hepatocellular carcinoma

Previous reports of a solitary metastatic hepatocellular carcinoma have been rare. Because this tumor has a different treatment modality and prognosis, an accurate differential diagnosis is essential. Here we report a rare case of a solitary chest wall metastasis from unknown primary site of hepatocellular carcinoma. It involves a 51-year-old man who was admitted to our hospital because of a palpable left upper chest wall mass. The mass was resected and pathologic examination confirmed a diagnosis of metastatic hepatocellular carcinoma. Despite our investigation, no evidence was found that indicated the primary origin of the hepatocellular carcinoma. Four months later, the patient was admitted again because of spinal cord compression at the third and fourth thoracic vertebrae. Emergent decompressive laminectomy was performed and microscopic features revealed the same pathology as the initial chest wall mass resected 4 months earlier. After one year, a follow-up abdominal computed tomography （CT） still revealed no evidence of primary hepatocellular carcinoma.

Accurate Diagnosis of SARS-CoV-2 JN.1 by Sanger Sequencing of Receptor-Binding Domain Is Needed for Clinical Evaluation of Its Immune Evasion

引用

Journal of Biosciences and Medicines 2024年第4期12卷 69-78页

作者： Sin hang lee Milford Molecular Diagnostics Laboratory Milford CT USA

Background: Omicron JN.1 has become the dominant SARS-CoV-2 variant in recent months. JN.1 has the highest number of amino acid mutations in its receptor binding domain (RBD) and has acquired a hallmark L455S mutation. The immune evasion capability of JN.1 is a subject of scientific investigation. The US CDC used SGTF of TaqPath COVID-19 Combo Kit RT-qPCR as proxy indicator of JN.1 infections for evaluation of the effectiveness of updated monovalent XBB.1.5 COVID-19 vaccines against JN.1 and recommended that all persons aged ≥ 6 months should receive an updated COVID-19 vaccine dose. Objective: Recommend Sanger sequencing instead of proxy indicator to diagnose JN.1 infections to generate the data based on which guidelines are made to direct vaccination policies. Methods: The RNA in nasopharyngeal swab specimens from patients with clinical respiratory infection was subjected to nested RT-PCR, targeting a 398-base segment of the N-gene and a 445-base segment of the RBD of SARS-CoV-2 for amplification. The nested PCR amplicons were sequenced. The DNA sequences were analyzed for amino acid mutations. Results: The N-gene sequence showed R203K, G204R and Q229K, the 3 mutations associated with Omicron BA.2.86 (+JN.1). The RBD sequence showed 24 of the 26 known amino acid mutations, including the hallmark L455S mutation for JN.1 and the V483del for BA.2.86 lineage. Conclusions: Sanger sequencing of a 445-base segment of the SARS-CoV-2 RBD is useful for accurate determination of emerging variants. The CDC may consider using Sanger sequencing of the RBD to diagnose JN.1 infections for statistical analysis in making vaccination policies.

FULLY NONLINEAR WAVE COMPUTATIONS FOR ARBITRARY FLOATING BODIES USING THE DELTA METHOD

引用

Journal of Hydrodynamics 2003年第2期15卷 24-31页

作者： lee Tzung hang DepartmentofMechanicalEngineering

Fully nonlinear water wave problems are solved using Eulerian-Lagrangian timestepping methods in conjunction with a desingularized approach to solve the mixed boundary valueproblem that arises at each time step. In the desingularized approach, the singularities generatingthe flow field are outside the fluid domain. This allows the singularity distribution to be replacedby isolated Rankine sources with the corresponding reduction in computational complexity andcomputer time. A moving boundary technique is applied to e-liminate the reflection waves fromlimited computational boundaries. Examples of the use of the method in three-dimensions are givenfor the exciting forces acting on a modified wigley hull and Series 60 are presented. The numericalresults show good agreements with those of experiments.
