Expression of core?binding factor alpha 1 and collagen Ⅱ in patients with chronic kidney disease stage 5

Objective To study the relationship between the medial artery calcification and expression of core?binding factor alpha 1 (Cbfα?1) and collagen Ⅱ (ColⅡ) in chronic kidney disease(CKD) stage 5 patients. Methods Pieces of radial arteries were taken from 40 patients with CKD stage 5 during internal arteriovenous fistula operation. Ten patients with subtotal gastrectomy and normal renal function were chosen as control. The vessels were examined for calcification by von Kossa stain and for the presence of Cbfα?1 and ColⅡ by immunohistochemistry. According to von Kossa stain, CKD stage 5 patients were divided into no calcification group, mild?moderate calcification group and severe calcification group. Other related factors including serum calcium，phosphate, intact parathyroid hormone (iPTH), C?reactive protein (CRP), triglyceride(TG), cholesterol(TC) and low?density lipoproteins(LDL) were also detected. Results Seventeen (42.5%) of CKD Stage 5 patients showed vascular calcification, while calcification was not found in controls. Most calcification occurred in medial layer．Positive immunohistochemical staining of core?binding factor and ColⅡ was found in the smooth muscular cell plasma of medial layer in the vessels with calcification. However, above positive staining was also observed in 78.3% of no calcification group. But there was little staining in control group. Positive staining score of Cbfα?1 and ColⅡ in severe calcification group was significantly higher than that in no calcification group. Same findings were obtained in mild?moderate calcification group, but the difference between them was not statistically significant. CRP and Ca×P were positively correlated with staining score of Cbfα?1 and ColⅡ. Serum phosphate was positively correlated with Cbfα?1 (r=0.786, P<0.01) and ColⅡ (r=0.785, P<0.01) respectively． Conclusions 42.5% of CKD stage 5 patients in our group shows vascular calcification, which occurrs mainly in medial layer. High expression of Cbfα?1 and ColⅡ can be observed in vascular calcification of radial arteries, which is earlier than vascular histological changes. Cbfα?1 and ColⅡ may be involved in the development of vascular calcification.

Defining Textbook Outcome in liver surgery and assessment of hospital variation: A nationwide population-based study

IntroductionTextbook outcome (TO) is a composite outcome measure covering the surgical care process in a single outcome measure. TO has an advantage over single outcome parameters with low event rates, which have less discriminating impact to detect differences between hospitals. This study aimed to assess factors associated with TO, and evaluate hospital and network variation after case-mix correction in TO rates for liver surgery.MethodsThis was a population-based retrospective study of all patients who underwent liver resection for malignancy in the Netherlands in 2019 and 2020. TO was defined as absence of severe postoperative complications, mortality, prolonged length of hospital stay, and readmission, and obtaining adequate resection margins. Multivariable logistic regression was used for case-mix adjustment.Results2376 patients were included. TO was accomplished in 1380 (80%) patients with colorectal liver metastases, in 192 (76%) patients with other liver metastases, in 183 (74%) patients with hepatocellular carcinoma and 86 (51%) patients with biliary cancers. Factors associated with lower TO rates for CRLM included ASA score ≥3 (aOR 0.70, CI 0.51–0.95 p = 0.02), extrahepatic disease (aOR 0.64, CI 0.44–0.95, p = 0.02), tumour size >55 mm on preoperative imaging (aOR 0.56, CI 0.34–0.94, p = 0.02), Charlson Comorbidity Index ≥2 (aOR 0.73, CI 0.54–0.98, p = 0.04), and major liver resection (aOR 0.50, CI 0.36–0.69, p < 0.001). After case-mix correction, no significant hospital or oncological network variation was observed.ConclusionTO differs between indications for liver resection and can be used to assess between hospital and network differences.     

Effects of old age on vascular complexity and dispersion of the hepatic sinusoidal network

OBJECTIVES: In old age, there are marked changes in both the structure of the liver sinusoidal endothelial cell and liver perfusion. The objective of this study was to determine whether there are also aging changes in the microvascular architecture and vascular dispersion of the liver that might influence liver function. METHODS: Vascular corrosion casts and light micrographs of young (4 months) and old (24 months) rat livers were compared. Fractal and Fourier analyses and micro-computed tomography were used. Vascular dispersion was determined from the dispersion number for sucrose and 100-nm microspheres in impulse response experiments. RESULTS: Age did not affect sinusoidal dimensions, sinusoidal density, or dispersion number. There were changes in the geometry and complexity of the sinusoidal network as determined by fractal dimension and degree of anisotropy. CONCLUSIONS: There are small, age-related changes in the architecture of the liver sinusoidal network, which may influence hepatic function and reflect broader aging changes in the microcirculation. However, sinusoidal dimensions and hepatic vascular dispersion are not markedly influenced by old age.

目的探讨乙型肝炎病毒（Hepatitis B Virus,HBV）前C基因区变异与HBV-DNA载量的关系。方法通过DNA扩增、基因序列分析检测21例慢性肝炎、18例肝硬化和15例肝癌血清的HBV前C区和基本核心启动子（Basic Core Promoter,BCP）基因序列,荧光定量聚合酶链反应技术定量检测血清中的HBV-DNA。结果野生株与前C区终止变异、BCP双变异以及联合变异组HBV-DNA载量测定差异无显著性（P〉0.05）;BCP双变异HBV-DNA载量HBeAg（-）组显著高于HBeAg（＋）组（P〉0.05）。结论前C区终止变异和BCP双变异对HBV DNA复制无明显影响。HBeAg（-）的慢性肝病患者BCP变异后HBV DNA复制明显活跃。     

Towards an ICF Core Set for chronic musculoskeletal conditions: commonalities across ICF Core Sets for osteoarthritis,rheumatoid arthritis,osteoporosis, low back pain and chronic widespread pain

The objective of the study was to identify commonalities among the International Classification of Functioning, Disability and Health (ICF) Core Sets of osteoarthritis (OA), osteoporosis (OP), low back pain (LBP), rheumatoid arthritis (RA) and chronic widespread pain (CWP). The aim is to identify relevant categories for the development of a tentative ICF Core Set for musculoskeletal and pain conditions. The ICF categories common to the five musculoskeletal and pain conditions in the Brief and Comprehensive ICF Core Sets were identified in three steps. In a first step, the commonalities across the Brief and Comprehensive ICF Core Sets for these conditions were examined. In a second and third step, we analysed the increase in commonalities when iteratively excluding one or two of the five conditions. In the first step, 29 common categories out of the total number of 120 categories were identified across the Comprehensive ICF Core Sets of all musculoskeletal and pain conditions, primarily in the component activities and participation. In the second and third step, we found that the exclusion of CWP across the Comprehensive ICF Core Sets increased the commonalities of the remaining four musculoskeletal conditions in a maximum of ten additional categories. The Brief ICF Core Sets of all musculoskeletal and pain conditions contain four common categories out of a total number of 62 categories. The iterative exclusion of a singular condition did not significantly increase the commonalities in the remaining. Based on our analysis, it seems possible to develop a tentative Comprehensive ICF Core Set across a number of musculoskeletal conditions including LBP, OA, OP and RA. However, the profile of functioning in people with CWP differs considerably and should not be further considered for a common ICF Core Set.
