This cross-sectional study evaluated the long-term health effects of coronavirus disease 2019(COVID-19)in Jianghan District(Wuhan, China). The results showed that 61.4% of COVID-19 patients reported at least one symptom and 8.8% had depressive symptoms at the 17-month follow-up. The proportion of patients with chest radiographic abnormalities in Fangcang shelter hospitals and designated COVID-19hospitals was 31.6% and 41.1%, respectively, and the proportion of patients with impaired pulmonary diffusion capacity in these hospitals was 52.8% and 60.9%, respectively. Female sex(odds ratio[OR] = 1.48, 95% confidence interval [CI]: 1.16–1.88), severe disease(OR = 1.46, 95% CI: 1.01–2.10)and a higher number of initial symptoms(OR = 1.31, 95% CI: 1.23–1.40) were associated with the development of sequelae symptoms at 17 months. This study involving community-dwelling COVID-19adults may help determine the long-term effects of COVID-19 during the first pandemic ***, larger follow-up studies are needed to characterize the post-COVID-19 condition.

BACKGROUND: Although a variety of tumor markers areavailable for diagnosis of pancreatic cancer, their sensitivityand specificity have not yet been ideal. The aims of thisstudy was to detect a panel of serum tumor markers and toevaluate their significance in the diagnosis and prognosis ofpancreatic cancer ***: Eight serum tumor markers including AFP,CEA, CA-50, CA72-4, CA-125, CA153, CA19-9 and CA242were detected in 129 patients with pancreatic cancer by usingchemiluminescence immunoassay, immunofluorescence as-say and immunoradiometric assay, respectively. The levelsof these markers were compared in 99 patients with non-pancreatic malignant tumor, 63 patients with other benigndiseases, and 27 patients with pancreatic cancer after ***: Among the 8 tumor markers, CA19-9, CA242,CA-50, and CA72-4 were more sensitive in the diagnosis ofpancreatic cancer. Parallel combined testing could increasethe diagnostic sensitivity to 89.2%, and serial combined exa-mination could increase the diagnostic specificity to 92.3%.The serum tumor markers levels were decreased significant-ly after radical tumor ***: Serum CA19-9, CA242, CA-50, andCA72-4 are the preferred tumor markers to be used in thediagnosis and follow-up of operated cases of pancreaticcancer. Testing of a panel of multiple serum tumor mark-ers may increase the sensitivity and specificity in the diag-nosis of pancreatic cancer.

Effect of small intestinal submucosa on islet recovery and function in vitro culture

引用

Hepatobiliary & Pancreatic Diseases International 2005年第4期4卷 524-529页

作者： xiao-Hui Tian Wu-Jun Xue Xin-Lu Pang Yan Teng Pu-Xun Tian Xin-Shun feng Department of Renal Transplantation First Affiliated Hospital College of Medicine Xi'an Jiaotong University Xi'an 710061 China.

BACKGROUND: The ability to maintain isolated human islet preparation in tissue culture has recently been adopted by most islet transplant centers to improve the safety and practicality of islet transplantation. However, maintaining islet viability and recovery remains a challenge in clinical setting. Extracellular matrix (ECM) is one of the most important components of islet microenvironment. The reconstruction of the cell-matrix relationship seems to be effective in improving the loss of differentiated islet structure and function. Small intestinal submucosa ( SIS ) , a naturally occurring ECM, has been investigated to be able to promote wound healing, tissue remodeling, and cell growth. The purpose of this study was to evaluate the recovery and function of isolated rat pancreatic islets after in vitro culture with SIS. METHODS: Pancreatic islets were isolated from Wistar rats by using standard surgical procurement followed by intra-ductal collagenase distension, mechanical dissociation, and EuroFicoll purification. Groups of purified islets were cultured in plates which were coated with multilayer SIS (SIS-treated group) or without ( standard cultured group) for 7 days and 14 days in standard islet culture conditions of RP-MI 1640 tissue culture media in humidified atmosphere containing 95% air and 5% CO2 at 37 ℃. The mean recovery of islets after the culture period was determined by sizing duplicate counts of a known volume and their viability was assessed by static incubation with low glucose (2.7 mmol) , high glucose (16.7 mmol) and high glucose solution supplemented with 50 μm 3-isobutyl-1-methylxanthine (IB-MX) solution. RESULTS: After 7 days and 14 days of in vitro tissue culture, the SIS-treated group showed a significantly higher recovery compared with those cultured under standard conditions. The recovery in the SIS-treated group was about two times of the control group cultured in standard conditions after 14 days culture. In the SIS-treated group, there
