ABSTRACT

ObjectiveTo investigate the clinical features of infection in patients with acute-on-chronic liver failure (ACLF) and bacterial infection and the influencing factors for 90-day survival rate. MethodsThe patients with ACLF who were admitted to The Fifth Medical Center of Chinese PLA General Hospital from January 2014 to December 2015 were enrolled, and related clinical data were collected and analyzed, including infection time and site, microbial culture, biochemical parameters and inflammatory markers, and 28- and 90-day prognosis after infection. The t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The life-table method was used to plot survival curves. The indices affecting prognosis in the univariate analysis were further included in the multivariate logistic regression analysis. ResultsA total of 1074 patients with ACLF were admitted, among whom 609 had bacterial infection, and the incidence rate of bacterial infection was 567%. Among these 609 patients, 16 underwent liver transplantation within 90 days and related data statistics were obtained for the remaining 593 patients. As for infection site, among the patients with infection, 70.15% had abdominal infection, 41.15% had pulmonary infection, 11.97% had sepsis, 5.40% had urinary system infection, 4.89% had thoracic infection, and 8.6% had infection at other sites. Among the patients with infection, 64.76% had infection at a single site. The positive rates of microbial culture of ascites, phlegm, urine, and pleural effusion were 22.70%, 52.82%, 40.63%, and 35.71%, respectively. Escherichia coli was the most common bacterium in ascites and accounted for 43.82%; Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii accounted for 22.67%, 2400%, and 22.67%, respectively, in phlegm; Escherichia coli, Klebsiella pneumoniae, and Staphylococcaceae accounted for 33.80%, 29.58%, and 15.49%, respectively, in blood culture. The 90-day survival rate after infection was 38.11% (226/593) in the patients with ACLF, and the multivariate logistic regression analysis showed that age (P=0.006), stage of hepatic encephalopathy (HE) (P<0001), stage of liver failure (P<0.001), and acute kidney injury (AKI) (P<0.001) were independent risk factors for 90-day survival in patients with ACLF and infection. ConclusionThere is a high incidence rate of infection in patients with ACLF. The 90-day survival rate is relatively low, and the presence of AKI, HE stage III or above, and advanced liver failure may indicate poor prognosis.

ABSTRACT

Objective To investigate the distribution of urinary iodine level and its relationship with thyroid function in Tibetan adults in Lhasa. Methods Tibetan residents living in Lhasa and its surrounding countryside were recruited by the method of multistage randomized cluster sampling. Their salt iodine, drinking water iodine, urinary iodine, and thyroid function levels were detected. According to the urinary iodine level, these subjects were divided into the iodine deficiency group ( urinary iodine<100μg/L) , the iodine enough group ( urine iodine 100-199μg/L) , the iodine adequate group ( urine iodine 200-299 μg/L ) and the iodine excessive group ( urine iodine≥300μg/L) . The differences in thyroid function among various groups were compared. Results A total of 2235 subjects were included in the study. The overall level of urinary iodine was in skewed distribution, with a median ( upper and lower quartiles) of 154 (99, 229) μg/L. The proportion of subjects with insufficient iodine intake was 25.7%, while those of the enough, adequate, and excessive groups were 41. 5%, 21. 3%, and 11. 5%, respectively. There was no significant difference in urine iodine level between males and females [152(95,219)μg/L vs 155(100,232)μg/L P>0.05]. The urinary iodine levels in residents of urban were higher than those in rural residents [157(101,232)μg/L vs 140(92,200)μg/L, P<0.05]. The urinary iodine levels in the young, middle-aged, and elderly groups were 175 ( 116,256) , 136 ( 91, 200) , and 116 ( 68, 164)μg/L respectively, showing a gradual decrease in urine iodine level with aging (P<0.05). The average salt iodine content of Tibetan adults in Lhasa was 23.16 mg/kg, and that in drinking water was 4.33μg/L. There were no significant differences in TSH levels among various iodine intake groups ( P>0.05) . The levels of thyroid peroxidase antibody ( TPOAb) and thyroglobulin antibody ( TGAb) were gradually decreased with the increase of urinary iodine level (P<0.05). Conclusion More than 50% of Tibetans are at the status of low iodine and high iodine intakes in Lhasa. Although the salt iodine content meets national standards, the drinking water iodine content is lower than that standard.

ABSTRACT

Objective To investigate the changes of red blood cells (RBC) and blood lipid in Han high altitude immigration dur‐ing the process of altitude acclimatization and their correlation .Methods Forty male Han nationality teachers entering Xizang Ali area and working for 1 year were selected .The blood samples were collected before entering plateau and within 3 d after returning to plain .The blood routine and the blood lipid level were detected .Results In the early return to plain ,the RBC ,TG ,CHO and LDL‐C levels in the research subjects were increased ,in which RBC and TG were significantly increased (P< 0 .01) ,HDL‐C was significantly decreased .After returning to plain ,RBC was positively correlated with TG and CHO (r=0 .46 ,P<0 .01 and r=0 .36 , P<0 .05) .Conclusion High altitude hypoxia environment is the primary cause leading to the change of RBC and blood lipid inde‐xes in the plain population after entering the plateau environment .

ABSTRACT

Objective To study the changes of cardiac structure,heart function and pulmonary arterial pressure of the Han Chinese back to the plain after living long time on Tibetan Plateau. Methods Randomly choose 67 cases out of the Han people who have moved to the Tibetan Plateau many years , and been examined to make sure they have no disease caused by other factors. Examine their cardiac structure, heart function, pulmonary arterial pressure and valve flow velocity in Tibetan Plateau and about 60 days later back in plains respectively. Then make statistical analysis of high altitude cardiopulmonary adaptation and de-adaptation reaction according to the differences. Results Only were the values of pulmonary artery systolic pressure (PASP) and tricuspid regurgitation (TR) from the group back to plains lower than those from the group migrated to plateau (P = 0.045; P = 0.041). Other indicators of cardiac structure, heart function, pulmonary arterial pressure and valve flow velocity did not change significantly between the group back to plains and the group migrated to plateau (P > 0.05). Conclusions To Han people who returned to plains about 60 days later after long time staying on plateau , only the values of PASP and TR significantly reduce , which have not recovered to normal levels. This may be correlated with the ageing factor and long time migrating.
