ABSTRACT
ObjectiveTo investigate the prevalence rate of gallstones among university teachers in Tianjin, China, and related risk factors. MethodsPhysical examination data were collected from the teachers from five universities who participated in physical examination in Physical Examination Center, Tianjin Medical University Cancer Institute and Hospital, in 2015, and abdominal ultrasound was used for the diagnosis of gallstones. The chi-square test was used for comparison of categorical data between groups. Univariate and multivariate logistic regression analyses were used to identify the risk factors for gallstones in the teachers from different universities, and a meta-analysis was used for the pooled analysis of prevalence rate and risk factors. ResultsA total of 8006 university teachers were enrolled, among whom 440 were diagnosed with gallstones, and the pooled prevalence rate of gallstones was 5.5%. The meta-analysis showed that hypertension (odds ratio ［OR］=1.67, 95% confidence interval ［CI］: 1.32-2.12, P＜0.001), fatty liver (OR=1.39, 95%CI: 1.12-1.72, P＜0.001), kidney stones (OR=1.90, 95%CI: 1.15-3.14, P=0.01), and high levels of hexokinase (OR=1.42, 95%CI: 1.03-1.94, P=0.03), alanine aminotransferase (OR=1.32, 95%CI: 1.01-1.73, P=0.04), and globulin (OR=1.74, 95%CI: 1.08-2.79, P=0.02) were risk factors for gallstones. ConclusionThere is a relatively low prevalence rate of gallstones among university teachers in Tianjin, and hypertension, fatty liver, kidney stones, and high levels of hexokinase, alanine aminotransferase, and globulin may be the risk factors for gallstones.
ABSTRACT
Objective To establish serum NGAL reference range of healthy populations in Xi'an Area.Methods 2 665 cases (aged 6 to 95 years old,male 1 370,female 1 295) of health-check people were collected from March 2014 to October 2016 in Medical Examination Center of Shaanxi Provincial People's Hospital,and 682 cases (aged 0 to 6 years old,male 356,female 326) were collected from preschool children of prevention.Serum NGAL concentration of them were analysed by immunoturbidimetry method with the Automatic Biochemical Analysis Assembly Line of Beckman-AU5800,and the detection data for statistical analysis.Then established the reference range of serum NGAL population of different age and different sex in Xi'an.Results The serum NGAL levels in healthy subjects showed a skewed distribution,which were preschool children under 6 years of age 37.66±23.12 ng/ml,6～15 years 39.25±25.34 ng/ml,16～49 years 46.68±27.06 ng/ml,and 50～ 69 years 57.82±29.13 ng/ml.Compared the first two with the latter,there was a significant difference (t=0.589,P＜ 0.05).The serum NGAL levels of over 70 years were 61.87 ± 32.64 ng/ml,and there was a significant difference between the ages of 15 and 49 and over 70 years (t=8.529,P＜0.01).At the same time,the serum NGAL was closely correlated with age (r=0.298,P＜0.01).But there was no significant difference in serum NGAL level between male and female (t=0.263～0.542,all P＞0.05).87ng/ml was the upper limit of the reference value for the age of 50 years.Conclusion The level of serum NGAL was related to age and increased with age,but not with gender.
ABSTRACT
Objective With density in healthy people pharyngeal flora of the reference[1],study the respiratory tract infection and the treatment process of the change of density and pharyngeal flora infection treatment of correlation analysis,by using the density of the pharyngeal flora changes to evaluate the treatment of patients with respiratory tract infection and progno-sis.Methods Collected 102 cases of patients with upper respiratory tract infection and 219 cases of lower respiratory tract infection in patients with pharyngeal swab for bacterial culture,study clinical symptom change with the change of pharyngeal bacteria density of correlation.Results 62 cases of upper respiratory tract infection and the treatment group patients with pharyngeal flora normal no treatment group on the symptoms improved and recovered,no statistical difference (P >0.05), and 60 patients with upper respiratory tract infection and pharyngeal abnormal bacterium group the treatment group and treatment group in pharyngeal flora and CPIS score was statistically difference (P <0.05).For 219 patients with lower re-spiratory tract,including 121 cases of bacterial pneumonia,74 cases of severe pneumonia,and 24 cases of patients with lung abscess treatment observation,found that when back to normal pharyngeal flora,the accuracy of clinical pathological changes were 92.6%,86.5% and 87.5%,respectively.Conclmion Pharyngeal bacteria density between healthy people maintained a certain bacteria species and the number of stable,but when respiratory infections bacteria can disorders with the application of broad-spectrum antibiotics can lead to serious result in pharyngeal dysbacteriosis should be combined with pharyngeal bacteria in respiratory anti-infection treatment density changes to evaluate the clinical treatment,can reduce the number of days with antibiotics,patients with avoid induce drug-resistant bacteria and respiratory dysbacteriosis.
ABSTRACT
Objective To investigate the reasons of higher result of CK-MB than the total CK with the immune suppression method for deteting serum CK-MB and solution methods.Methods Selected 68 cases of inpatients with myocardial infarc-tion from Department of Cardiology,32 cases of malignant tumor from Internal Medicine-Oncology,including 8 cases of liver cancer,6 cases of lung cancer,6 cases of gastric cancer,5 cases of neuroblastoma,4 cases of breast cancer and 3 cases of o-varian cancer and 16 cases of cirrhosis from Department of Gastroenterology,and at the same time,selected 100 cases of healthy persons as control group from Out-patient Health Examination Center of Shaanxi Provincial People’s Hospital.Used Roche MODUALR automatic biochemical analyzer to detected the activity of serum CK-MB with the immune suppression method and the activity of total CK with the enzyme coupling rate method.Results In 68 cases of inpatients with myocardial infarction,the activity of serum CK-MB of 2 1 cases were individually increased,the activity of total CK of 3 9 cases were in-creased,and the two indexes of 30 cases were increased in the same period.In 32 cases of inpatients with malignant tumor, the activity of serum CK-MB of 1 1 cases were individually increased,the activity of total CK of 3 cases were increased and the two indexes of 3 cases were also increased.The activity of serum CK-MB of 6 cases were individually increased in 1 6 ca-ses of cirrhosis.Conclusion The immune inhibition assay for the detection of CK-MB as the diagnosis index of myocardial infarction had certain defects,and the higher activity of CK-MB could be highly associated with some severe inflammation, malignant tumor.
ABSTRACT
Objective To investigate the serum homocysteine (HCY)levels of patients with various liver diseases,and discuss the clinical value of combined detection of HCY and other liver function indicators in liver disease diagnosis.Methods Se-lected 123 cases of inpatients with different liver diseases (79 cases of male,44 cases of female),including 39 cases of chronic active hepatitis,52 cases of cirrhosis and 32 cases of primary hepatic cancer from Department of Gastroenterology,and 90 ca-ses of healthy persons as control group from Out-patient Health Examination Center of Shaanxi Provincial People’s Hospi-tal.Detected serum HCY and some indicators of liver function (TBIL,ALT,GGT and TBA)in different liver disease groups and normal control group with Roche MODUALR automatic biochemical analyzer,and did statistic analysis.Results The serum HCY levels of chronic active hepatitis,liver cirrhosis and primary hepatic cancer were 16.25± 3.98μmol/L,20.89± 4.26μmol/L and 22.92 ± 6.08μmol/L respectively,and significantly higher than those in normal control group (8.16 ± 4.03μmol/L,t=5.352~9.021,P<0.01).The serum HCY levels of liver cirrhosis and primary hepatic cancer group were higher than that of chronic active hepatitis group (P<0.05).Serum levels of HCY were obviously lower after treatment than that before treatment (P<0.05)for three groups of liver diseases.The positive rate of HCY was higher than those of other liver function indicators (P<0.05).Conclusion Serum homocysteine may be as one of the most important indexes of liver damage,and the combined detection of other liver function indicators may have important clinical value for liver disease diagnosis,differential diagnosis,treatment and prognosis.
ABSTRACT
Objective To evaluate the effect of sucralfate and acid-suppressive drugs on preventing ventilator-associated pneumonia (VAP) in mechanically ventilated patients.Methods All randomized controlled trials (RCTs),which studied the effect of sucralfate and acid-suppressive drugs on the incidence of VAP in mechanically ventilated patients,were searched from PubMed,Embase and the Cochrane Library during January 1966 to March 2013 via manual and computer retrieval.All related data were extracted.Meta analysis was conducted using the statistical software RevMan 5.2 and the quality of the RCTs was strictly evaluated with the methods recommended by the Cochrane Collaboration.Results A total of 15 RCTs involving 1315 patients in the sucralfate group and 1568 patients in the acid-suppressive drug group were included in this study.The incidence of VAP was significantly reduced in the sucralfate group (RR =0.81,95％ CI 0.7-0.95,P =0.008),while no difference was found between the two groups in the incidence of stress-related gastrointestinal bleeding (RR =0.96,95％ CI 0.59-1.58,P =0.88).No statistical difference was found in the days on ventilator,duration of ICU stay and ICU mortality in the two groups (all P values ＞ 0.05).Conclusion In patients with mechanical ventilation,sucralfate could decrease the incidence of VAP,while has no such effect on the stress-related gastrointestinal bleeding,the days on ventilator,duration of ICU stay and ICU mortality.
