AIM： To study the presence of sustained low diffusing capacity （DLco） after liver transplantation （LT） in patients with hepatopulmonary syndrome （HPS）. METHODS： Six patients with mild-to-severe HPS and 24 without HPS who underwent LT were prospectively followed before and after LT at mid-term （median, 15 mo）. HPS patients were also assessed at Iong-tem （median, 86 mo）. RESULTS： Before LT, HPS patients showed lower PaO2 （71 ± 8 mmHg）, higher AaPO2 （43 ± 10 mmHg） and lower DLco （54% ± 9% predicted）, due to a combination of moderate-to-severe ventilation-perfusion （VA/Q） imbalance, mild shunt and diffusion limitation, than non- HPS patients （94 ± 4 mmHg and 19 ± 3 mmHg, and 85% ± 3% predicted, respectively）（P 〈 0.05 each）. Seven non-HPS patients had also reduced DLco （70% ± 4% predicted）. At mid- and long-term after LT, compared to pre- LT, HPS patients normalized PaO2 （91 ± 3 mmHg and 87 ± 5 mmHg）, AaPO2 （14 ± 3 mmHg and 23 ± 5 mmHg） and all VA/Q descriptors （P 〈 0.05 each） without changes in DLco （53% ± 8% and 56% ± 7% predicted, respectively）. Post-LT DLco in non-HPS patients with pre- LT low DLco was unchanged （75% ± 6% predicted）. COnclUSIOn： While complete VA/Q resolution in HPS indicates a reversible functional disturbance, sustained low DLco after LT also present in some non-HPS patients, points to persistence of sub-clinical liver-induced pulmonary vascular changes.

High blood pressure is the main risk factor for cardiovascular diseases, it affects many people worldwide and is a public health problem. This study explored the acute and chronic actions of a mixture of turmeric (95% curcumin) plus black pepper (95% piperine) extracts, in the blood pressure pattern in spontaneously hypertensive rats (SHR) along they age. For the acute study male adult (4 - 7 months old) SHR and their control Wistar Kyoto rats (WKY) were used. A single oral dose of the mixture of turmeric/black pepper extracts (200 mg/2mg, respectively) suspension was administered. Tail-cuff was used to determine blood pressure during 180 min. For the chronic study, young (1-month-old) male SHR and their control WKY rats were fed with standard chow, or standard chow combined with cocoa, or combined with cocoa plus the mixture of turmeric/black pepper extracts;tail-cuff was used to determine blood pressure once a week, along 12 weeks. In a second chronic assay adult (5 months old) male SHR and their control WKY rats were fed with standard chow, or standard chow combined with cocoa, or combined with cocoa plus the mixture of turmeric/black pepper extracts;tail-cuff was used to determine blood pressure once a week, along 12 weeks. In all three studies, a decrease in systolic, diastolic and mean blood pressure was observed, being higher in SHR and negligible in WKY rats. The mixture of turmeric/black pepper extracts showed antihypertensive actions in SHR rats with no effect on WKY rats. The mixture delayed the onset of hypertension in young SHR rats.

Bezoars are accumulations of human or plant fiber located in the gastrointestinal tract of both humans and animals. Patients remain asymptomatic for several years, and the symptoms develop as these accumulations increase in size to the point of obstruction or perforation. We report the case of a 21-year-old patient at 10 d postpartum, who presented with acute abdomen associated with sepsis. Given the urgency of the clinical picture, at no point was the presence of a giant bezoar at gastric level suspected, specifically a trichobezoar. The emergency abdominal and pelvic ultrasound revealed only unspecific signs of perforated hollow viscus. Diagnosis was therefore made intraoperatively. A complete gastric trichobezoar was found with gastric perforation and secondary peritonitis. The peritoneal fluid culture revealed Candida glabrata.

AIM: To investigate the prognostic significance of resting heart rate in patients with acute coronary syndrome (ACS), independent of other known factors. METHODS: Patients 40 years of age or older who had been admitted with acute coronary syndrome (ACS) to one of the 94 hospitals participating in the Prevalence of Peripheral Arterial Disease in Patients with Acute Coronary Syndrome (PAMISCA) study were included. Patients were divided into two groups based on their resting heart rate (HR ≥ or ns were recording during a follow-up period of 1 year. RESULTS: There were 1054 ACS patients analyzed (43.5% with ST segment elevation and 56.5% without elevation). Mean age was 66.6 ± 11.7 years, 70.6% were male and 29.4% of subjects were female. During follow-up, more patients in the HR ≥ 70 bpm group were hospitalized for heart failure and they also had a higher mortality rate. In the multivariate analysis, a heart rate of ≥ 70 bpm was independently related to overall mortality during the follow-up period (hazard ratio 2.5; 95% confidence interval, 1.26-4.97, P = 0.009). COnclUSIOn: A resting heart rate ≥ 70 bpm in patients who survive an ACS is an indicator of a high risk of suffering cardiovascular events during follow-up.

AIM： TO determine the prevalence and clinical relevance of isolated antibodies to hepatitis B core antigen as the only marker of infection （“anti-HBc alone”） among human immunodeficiency virus （HIV） type-1 infected patients. Occult hepatitis B infection frequency was also evaluated. METHODS： Three hundred and forty eight histories from 2388 HIV-positive patients were randomly reviewed. Patients with serological markers of hepatitis B virus （HBV） infection were classified into three groups： past hepatitis, ＂anti-HBc alone＂ and chronic hepatitis. Determination of DnA from HBV, and RnA and genotype from hepatitis C virus （HCV） were performed on ＂anti-HBc alone＂ patients. RESULTS： One hundred and eighty seven （53.7%） HIV-positive patients had markers of HBV infection： 118 past infection （63.1%）, 14 chronic hepatitis （7.5%） and 55 ＂anti-HBc alone＂（29.4%）. Younger age [2.3-fold higher per every 10 years younger; 95% confidence intervals （cl） 1.33-4.00] and antibodies to HCV infection [odds ratio （OR） 2.87; 95% CI 1.10-7.48] were factors independently associated with the ＂anti-HBc alone＂ pattern. no differences in liver disease frequency were detected between both groups. Serum levels of anti-HBs were not associated with HCV infection （nor viral replication or HCV genotype）, or with HIV replication or CD4 level. no ＂anti-HBc alone＂ patient tested positive for HBV DnA. COnclUSIOn：＂Anti-HBc alone＂ prevalence in HIM- positive patients was similar to previously reported data and was associated with a younger age and with antibodies to HCV infection. In clinical practice, HBV DnA determination should be performed only in those patients with clinical or analytical signs of liver injury,

Facile Preparation of 1,2-Diols from Chalcones: An nMR Spectroscopy and X-Ray Crystallography Study

引用

International Journal of Organic Chemistry 2015年第3期5卷 137-146页

作者： Marco A. Obregón-Mendoza María Miriam Estévez-Carmona Carolina Escobedo-martínez Manuel Soriano-García Raúl G. Enríquez Instituto de Química Universidad Nacional Autónoma de México Ciudad Universitaria México City México Departamento de Farmacia División de Ciencias Naturales y Exactas del Campus Guanajuato Universidad de Guanajuato México

Structures of 2-(naphthalen-2-ylmethyl)-2,3-dihydro-1H-indene-1,2-diol (C20H18O2), compound 1 and 1-(3,4-dimethoxyphenyl)-3-methoxy-3-(4-nitrophenyl)propane-1,2-diol chloroform (C18H21nO7·CHcl3) compound 2 were established by spectral and X-ray diffraction studies. Compound 1 crystallizes in the orthorhombic space group P212121 with unit cell parameters a = 5.2177 (6), b = 13.903 (2), c = 21.121 (2) A, Z = 4. Compound 2 crystallizes in the triclinic space group P-1 with unit cell parameters a = 9.238 (1), b = 9.879 (1), c = 12.636 (1) A, α = 102.004 (1), β = 92.356 (1), γ = 90.779 (1)o, Z = 2. These two new molecules arise from a facile preparation of 1,2-diols from chalcones and have been fully characterized. Based on the crystallographic information obtained for compound 1, the relative configuration for the chiral centers is 1S and 2S. In structure 1, both hydroxyl groups adopt an anti-conformation with a torsion angle O1-C1-C2-O2 value of 93.1 (2)o [in molecule 2, both hydroxyl groups adopt a trans-conformation with a torsion angle O1-C1-C2-O2 value of -171.0 (2)。]. In both structures, the molecules in the crystal are linked by intermolecular hydrogen bonds O-H···O and C-H···O interactions and adjacent molecules are interconnected by intermolecular weak C-H···π and C-H···cl interactions which give additional support to molecular packing stability.
