Community-acquired pneumonia(CAP)poses a significant global health threat,particularly affecting vulnerable *** and scoring systems play a crucial role in diagnosing,assessing severity,and guiding treatment decisions for CAP *** like C reactive protein,procalcitonin,and the neutrophil-to-lymphocyte ratio aid in diagnosis and severity assessment,while scoring systems such as CURB-65 and Pneumonia Severity Index classify patients into risk *** biomarkers(uremia,elevated respiratory rate,hypotension,and age≥65)like serum amyloid A and S100 proteins show promise in predicting disease severity and ***,further research is needed to determine their precise roles and clinical utility in CAP management.

AIM: To investigate the effects of fibrin sealant on hemostasis and liver regeneration and intra-abdominal adhesions in an experimental liver injury. METHODS: Thirty-six Wistar rats were randomly divided into primary suture group (n = 15), fibrin sealant group (n = 15) and control group (n = 6). A wedge resection was performed on the left lobe of the liver. In primary suture group, liver was sutured using polypropylene material, while fibrin glue was administrated on the liver surface in fibrin sealant group. RESULTS: More intra-abdominal adhesions were observed in the primary suture group compared to the fibrin sealant group on 3rd (2.50 ± 0.5 vs 0.25 ± 0.5, P = 0.015), 10th (2.75 ± 0.5 vs 0.50 ± 0.6, P = 0.06) and 20th (1.75 ± 0.5 vs 0.70 ± 0.5, P = 0.015) postoperative days. Histopathological scores were better in the fibrin sealant group in comparison with the primary suture group on 3rd (8.75 ± 0.5 vs 6.75 ± 0.5, P = 0.006), 10th (7.50 ± 1.0 vs 5.5 ± 0.6, P = 0.021) and 20th (6.40 ± 1.7 vs 3.20 ± 1.6, P = 0.025) postoperative days. CONCLUSION: Out data suggest that fibrin sealant is preferred over primary suture in appropriate cases including liver trauma since it causes less intra-abdominal adhesions while allowing shorter hemostasis time as assessed in experimental liver trauma.

Effects of the myeloperoxidase 463 gene polymorphisms on development of atrophy in H pylori infected or noninfected gastroduodenal disease

引用

World Journal of Gastroenterology 2007年第8期13卷 1243-1246页

作者： mer Yilmaz hakan Dursun Nesrin Gürsan ibrahim Pirim arif Yilmaz Nihat Okcu Department of Gastroenterology Faculty of Medicine University of Atatürk Erzurum 25070 Turkey Department of Pathology Faculty of Medicine University of Atatürk Erzurum 25070 Turkey Department of Medical Biology and Genetics Faculty of Medicine University of Atatürk Erzurum 25070 Turkey

AIM： To investigate the relationship between myeloperoxidase polymorphisms as a host-related factor and atrophy caused by H pylori. METHODS： Our study enrolled 77 patients. Biopsy materials obtained during gastrointestinal endoscopies were evaluated for the presence of H pylori. Polymerase chain reaction-restriction fragment length polymorphism assay was used to characterize myeloperoxidase genothpes. RESULTS： Forty four patients （57.1%） were lip （＋） and 33 （42.9%） were Hp （-）. Sixty six （85.7%） had GG genotype, 10 （12.9%） had GA genotype and 1 （1.29%） had AA genotype. The change in atrophy in relation to neutrophil infiltration was significant in Hp （＋） patients （P = 0.0001）. The change in atrophy in relation to neutrophil infiltration in patients with GG genotype was significant （P = 0.002）. However, the change in atrophy in relation to neutrophil infiltration was not significiant in patients with Hp （＋） GG genotype （r = 0.066, P = 0.63）. CONCLUSION： Myeloperoxidase genotype is critical for development of atrophy in relation to the severity of inflammation. However, it is interesting to note that, H pylori does not show any additive effect on development of atrophy.
