ABSTRACT
As an industrial chemical， bisphenol A is widely used in various food packaging materials. However， it is an endocrine disrupting chemical， which has estrogen activity and can cause certain damage to humans. So far， there are few studies on the detection of bisphenol A in self-heating food packaging materials， and there remains a lack of relevant standard. Therefore， it is necessary to establish a simple， sensitive and efficient method for the detection of bisphenol A in self-heating food. This study briefly introduces the pretreatment methods of bisphenol A， such as ultrasonic extraction， solid phase extraction， accelerated solvent extraction， and detection methods， such as gas chromatography-mass spectrometry， high performance liquid chromatography， fluorescent detection， and electrochemical detection.
ABSTRACT
ObjectiveTo investigate the influencing factors for chronic kidney disease (CKD) in patients with hepatitis B cirrhosis within 3 years. MethodsA total of 376 patients with hepatitis B cirrhosis who attended Beijing Ditan Hospital, Capital Medical University, from January 2014 to July 2017 were enrolled and followed up for 3 years, and according to the presence or absence of CKD, they were divided into CKD group with 23 patients and non-CKD group with 353 patients. Related general information and laboratory markers were collected. The t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups; a stepwise forward Cox regression analysis was used to screen out the independent influencing factors for CKD within 3 years in patients with hepatitis B cirrhosis. The area under the receiver operating characteristic curve (AUC) was used to investigate the value of the influencing factors in predicting CKD in patients with hepatitis B cirrhosis; the Kaplan-Meier method was used for survival analysis, and the log-rank test was used for comparison of the cumulative incidence rate of CKD between the patients with different risks. ResultsThe multivariate Cox regression analysis showed that age (hazard ratio ［HR］=1.078, 95% confidence interval ［CI］: 1.007-1.114, P=0.026), albumin (Alb) (HR=0.923, 95% CI: 0.860-0.989, P=0.024), and estimated glomerular filtration rate (eGFR) (HR=0.977, 95% CI: 0.955-0.999, P=0.037) were independent influencing factors for CKD within 3 years in patients with hepatitis B cirrhosis. Age, Alb, and eGFR had a relatively good value in predicting CKD, with AUCs of 0.701, 0.710, and 0.706, respectively. The Kaplan-Meier survival curve showed that the patients with baseline age ≥55 years, Alb ＜32 g/L, and eGFR ≥60 ml·min-1·1.73 m-2 and ＜76 ml·min-1·1.73 m-2 had a higher risk of CKD (χ2=9647, 13621, and 30.940, all P＜0.05). ConclusionRenal function should be closely monitored for patients with old age and low Alb and eGFR levels.
ABSTRACT
Acute-on-chronic liver failure (ACLF) is a reversible and complex clinical syndrome caused by various factors in patients with pre-existing chronic liver diseases, with the clinical features of acute liver function decompensation and high short-term mortality rate. ACLF has a complex pathogenesis, rapid progression, and a dangerous prognosis, and early and accurate prediction of prognosis is of vital importance. At present, there is still no ideal therapy for ACLF, and in recent years, integrated traditional Chinese and Western medicine therapy has achieved a certain effect in the treatment of this disease. This article reviews the advances in prognostic evaluation and integrated traditional Chinese and Western medicine therapy for ACLF, in order to provide guidance to prognostic evaluation of ACLF and selection of the regimens of integrated traditional Chinese and Western medicine therapy.
ABSTRACT
Objective To explore risk factors of depression in patients with polycystic ovarian syndrome (PCOS).Methods 142 patients diagnosed as PCOS and meeting criterions were collected from Aug.2013 to Nov.2016 in our hospital.Demographic data,menstrual status,signs,serum hormone levels,treatment were collected and recorded.The degree of depression was evaluated by Hamilton Depression scale (HAMD).They were divided into two groups:depression and non-depression group.Univariate x2 test and multivariate logistic regression analysis were used to explore risk factors for complicating depression in patients with PCOS.Results Depression occurred in 44 patients (30.98％),with 28 cases of mild depression,14 cases of moderate depression,and 2 cases of severe depression.Univariate x2 test revealed that BMI (x2=4.385,P=0.036),infertility (x2=8.367,P=0.004),LH/FSH (x2=4.592,P=0.032) and serum levels of FT (x2=5.777,P=0.016) were factors related to depression.Multivariate logistic regression analysis revealed that BMI＞25 kg/m2 (OR=12.874,95％ CI:1.675～75.824,P=0.013),infertility (OR=17.526,95％ CI:1.436～94.335,P=0.008),LH/FSH＞2 (OR=7.326,95％ CI:1.263～43.128,P=0.021) and abnormal FT (OR=9.724,95％ CI:3.625～56.524,P=0.016) were risk factors of depression.Conclusions Patients with PCOS have mild or moderate depressive tendencies.BMI＞25 kg/m2,infertility,LH/FSH＞2,abnormal FT were the risk factors of depression.
ABSTRACT
Accumulating evidence has shown that neutrophil-lymphocyte ratio (NLR), as an assessment index for inflammatory response, is closely related to the prognosis of various malignant tumors. This article summarizes the research advances in the relationship of NLR with overall survival, disease-free survival, and pathological features of hepatocellular carcinoma and related mechanisms of action, and points out that NLR is a convenient, economic, and effective predictor for the prognosis of patients with hepatocellular carcinoma.
ABSTRACT
Recent studies have found that endotoxin not only activates immune response,exacerbates liver injury,and induces liver failure, but also plays an important role in the development of hepatic encephalopathy,hepatorenal syndrome,spontaneous bacterial peritonitis,and other fatal complications.The recent progress in research on the pathogenesis of intestinal endotoxemia (IETM)and its impact on the devel-opment and progression of liver failure is reviewed and summarized.It is suggested that seeking effective methods to prevent and control IETM holds promise as the key to treating severe liver disease and liver failure successfully.
