An accurate, fast and sensitive method based on high performance liquid chromatography was established for the simultaneous determination of eleven ultra-violet absorbents in cosmetics. Eleven ultra-violet absorbents were baseline separated on an Acclaim C18 column within 11. 5 min using acetonitrile-0. 1%formic acid in water ( V/V) mobile phase, and detected at 361 nm with UV detection. Under the optimized conditions, the relative standard derivations ( RSDs) of the eleven ultra-violet absorbents were all less than 0. 1% for retention time, and less than 1. 2% for peak area; good linearity was obtained from 5 to and 500 mg/L with the correlation coefficients of above 0 . 9990 for these analytes; the recoveries spiked in a cosmetic sample were in the range of 77% -116%. Benzophenone-3, butylmethoxydibenzoylmethane, ethylhexylsalicylatec and homosalate were found in the detected cosmetic samples, and the concentration of homosalate was the highest. The results indicated that this method had potential for applications due to its convenience, accuracy and sensitivity. Oxybenzone, butylmethoxydibenzoylmethane, 2-ethylhexyl salicylatec and homosalate were found in the detected cosmetic samples, and the concentration of homosalate was the highest.

Objective To investigate the imaging features and the relationship with pathological characteristics of chromophobe cell renal carcinoma (CCRC).Methods The clinicopatholocal manifestations and CT or MRI imaging findings were analyzed retro-spectively in 23 patients with surgically confirmed CCRC.The location,shape,size,density,border,blood supply and invasion of adjacent organs of CRCC,especially the dynamic enhanced mode,were mainly analyzed and compared with pathology.Results The 23 cases of CCRC showed unilateral single mass on CT and MRI scans,and 12 located in right kidney while 1 1 in left kidney.The size ranged from 27-330 mm in diameter,and round or oval-shaped soft tissue mass was observed.The boundaries of 1 6 cases were clear,and 3 cases of mass broke through renal capsule,3 invaded renal pelvis,perirenal fat,renal vein and inferior vena cava,2 ca-ses with retroperitoneal lymph node metastases.18 cases were scanned by CT and the mass presented as soft tissue density on plain CT (CT value 30-44 HU).6 cases were scanned by MRI with abnormalities presenting with iso or hypo-intense on the T1 WI,hy-per or hypo-intense on the T2 WI,and 2 cases of pseudocapsule were showed as circled hypointense on T2 WI.According to the dy-namic enhancement,23 cases of CCRC were divided into three type:(1 )Mild-to-moderate enhanced type(n= 14):including mild homogeneous strengthening (n=7)and mild heterogeneous strengthening (n=7);(2)Significantly enhanced type(n=7):including heterogeneous enhancement(n=6)and uniform enhancement(n=1);(3)Spokes shape or scar enhancement(n=2).The sample of CCRC was mainly solid and showed yellowish-brown or brown section.According to the situation of HE staining,the characteristic microscopic features were divided into three types:the typical,acidophil type and mixed type.Conclusion Combined imaging find-ings of CT dynamic enhanced mode can provide characteristic information for diagnosis of CCRC,and comprehensive analysis of the imaging findings will contribute to the diagnosis and differential diagnosis.

Objective To compare the simple cases of hand-foot-mouth disease(HFMD) with HFMD patients complicated with encephalitis and HFMD cases complicated with pulmonary edema (PE). To explore predictor factors of disease progression and unfavorable prognosis. Methods Forty-one EV71-infected children admitted to the Fuyang First People's Hospital in Anhui Province from March to May in 2008 were investigated in the research, who were classified as encephalitis-complicated cases ( encephalitis group, n = 15 ), PE-complicated cases ( PE group, n = 15 ) and simple cases (simple group, n= 11 ). Their clinical manifestation, laboratory findings, and immunophenotypes of peripheral blood lymphocyte were analyzed to find predictors associated with disease progression and unfavorable outcomes. Results The mortality rate in PE group was 66.7%, which was significantly higher than that in encephalitis group. Ninty-three point three percent cases in PE group and encephalitis group were younger than 3 years old, with statistic difference compared to simple group. Patients in PE group had higher total blood white cell (WBC) counts and higher absolute neutrophil counts and tended to have higher breathing rate, heart i'ate and glucose level than encephalitis group. The percentages of T cells and natural killer (NK) cells were significantly lower among patients complicated with encephalitis than simple HFMD patients.Conclusions PE is one predictor for poor prognosis. Factors correlated with unfavorable outcome include high WBC, high absolute neutrophil counts; elevated breathing rate, heart rate and glucose level. The immunophenotypes of peripheral blood lymphocytes can also predict the disease progression.

Objective:To evaluate the associations of depression and anxiety statues with serum inflammatory biomarkers in elderly patients with chronic heart failure.Methods:From January 2018 to January 2020, 225 elderly patients with chronic heart failure were enrolled from our hospital. Zung Self-Rating Depression Scale (SDS) and Zung Self-Rating Anxiety Scale (SAS) were performed in all patients to determine if the patients were with depression and anxiety statues and evaluate the degrees of depression and anxiety. The differences in demographic and clinical data, geriatric comprehensive assessment indicators, and serum inflammatory markers were compared among patients in the control group (without depression and anxiety), depression group, anxiety group, and depression and anxiety group (with both depression and anxiety). Spearman correlation test was used to analyze the correlation between the levels of serum inflammatory markers and the degrees of depression and anxiety in patients with depression and anxiety. Binary Logistic regression analysis was used to determine the independent influencing factors for depression and anxiety.Results:(1) As compared with those in the control group, patients in the depression group, anxiety group, and depression and anxiety group had significantly increased scores of Chinese version of Tilburg Frailty Indicator, statistically decreased Mini Mental State Examination (MMSE) scores, significantly increased Minnesota Living with Heart Failure Questionnaire (MLWHFQ) scores, increased proportions of patients with 2-4 kinds of diseases and those taking 2-4 kinds of drugs, and decreased Basic Activity of Daily Living (BADL) scores ( P<0.05); as compared with those in the depression group and the anxiety group, the changes of the above indicators in the depression and anxiety group were more obvious with significant differences ( P<0.05). As compared with those in the control group, patients in the depression group, anxiety group, and depression and anxiety group had significantly increased serum interleukin (IL)-6 and C-reactive protein (CRP) levels, patients in the anxiety group and depression and anxiety group had statistically elevated serum homocysteine (Hcy) level, and patients in the depression group and depression and anxiety group had significantly increased serum tumor necrosis factor α (TNF-α) level ( P<0.05); the serum levels of CRP, Hcy and TNF-α in patients from the depression and anxiety group were significantly higher than those in depression group ( P<0.05); the levels of IL-6, CRP, Hcy and TNF-α in the depression and anxiety group were significantly higher than those in the anxiety group ( P<0.05). As compared with that in the control group, the proportion of patients with nutritional risk in the depression and anxiety group was statistically higher ( P<0.05). (2) The serum levels of IL-6, CRP and TNF-α in depression patients were positively correlated with the depression degrees ( P<0.05); the serum levels of IL-6, CRP and Hcy in anxiety patients were positively correlated with the anxiety degrees ( P<0.05). (3) Results of binary Logistic regression analysis showed that IL-6 was an independent risk factor for depression in elderly patients with chronic heart failure ( OR=1.093, 95%CI: 1.049-1.139, P=0.000); Hcy was an independent risk factor for anxiety in elderly patients with chronic heart failure ( OR=1.114, 95%CI: 1.030-1.205, P=0.007); CRP, TNF-α, IL-6 and Hcy were independent risk factors for depression and anxiety in elderly patients with chronic heart failure ( P<0.05). Conclusion:The depression and anxiety degrees and expressions of inflammatory markers in elderly patients with chronic heart failure have synergistic effects.

Objective:To evaluate the nutritional status of elderly inpatients with heart failure, and to analyze risk factors for malnutrition.Methods:A total of 221 patients with heart failure in our hospital from January 2018 to March 2019 were enrolled in the study.The demographic characteristics and medical record data were collected.All patients received Nutritional Risk Screening 2002(NRS-2002)and a questionnaire survey relating to heart failure.We investigated the effects of risk factors on the detection rate of malnutrition by using Mann-Whitney U test or Chi-square test, and the independent risk factors for malnutrition were analyzed by multivariate Logistic regression analysis.Results:The detection rate of nutritional risk was 45.2% in 221 patients.The detection rate of nutritional risk increased along with lower degree of education and worse cardiac function( P<0.05). The detection rate of nutritional risk was higher in patients with peripheral vascular disease and osteoporosis than in patients without them( P<0.05), and in patients with the increased numbers of complication and drugs( P<0.05). Patients with nutritional risk had a higher degree of frailty and a worse quality of activities of daily living( P<0.05). Multivariate Logistic regression analysis indicated that great age, ejection fraction, B-type natriuretic peptide(BNP), NYHA classification, numbers of drugs and diseases, frailty, low quality of life were independent risk factors for nutritional risk, and Digoxin was the independent protective factor for nutritional risk( P<0.05). Conclusions:The great age, severity of heart failure, numbers of drugs and diseases, frailty, low quality of daily life may be the independent risk factors for nutritional risk in elderly patients with heart failure, and oral Digoxin may be the independent protective factor for nutritional risk.

Objective To preliminarily explore the anti?cancer efficiency of disulfide?bonded hyaluronic acid?functionalized targeted sodium?meter probe for hepatocellular carcinoma and the feasibility of MRI. Methods Twenty?one nude mice models of subcutaneous liver cancer transplantation were randomly divided into saline, hyaluronic acid?poly ε?caprolactone@ doxorubicin/superparamagnetic iron oxide (HA?PCL@DOX/SPIO) and HA?disulfide?bonded?PCL@DOX/SPIO (HA?SS?PCL@DOX/SPIO) groups, with 7 mice in each group. The experimental groups were injected with micelles at a dose of Fe 5 mg/kg through the tail vein, and the control group was injected with the same amount of saline via the tail vein. MRI was performed before and after injection (2 h, 4 h, 8 h). The T2 value of the region of interest (tumor) was measured and its decline rate was calculated. Twenty?one nude mice models of orthotopic liver cancer transplantation were randomly divided into saline group,HA?PCL@DOX/SPIO and HA?SS?PCL@DOX/SPIO groups, with 7 mice in each group. The experimental groups were injected with micelles at a dose of DOX 2 mg/kg through the tail vein by three consecutive times a day apart, and the control group was injected with the same amount of saline through the tail vein. Continuous observation for 15 days to calculate tumor inhibition rate. One way ANOVA test was used. Results The T2 value of HA?SS?PCL@DOX/SPIO group decreased significantly after 2, 4 and 8 hours (P<0.05) than initial time, which was distinct compared with HA?PCL@DOX/SPIO group. The growth rate of tumor in HA?SS?PCL@DOX/SPIO and HA?PCL@DOX/SPIO groups was significantly lower than that in the control group (F=21.513,P<0.05). The former had the most obvious inhibitory effect on orthotopic liver cancer (47.7% and 28.2%). Conclusion Disulfide?bonded hyaluronic acid?functionalized targeted sodium?meter probe for hepatocellular carcinoma(HA?SS?PCL@DOX/SPIO) has high anti?cancer efficiency and imaging function at the animal level in vivo, and can be used to monitor the early therapeutic effect of tumor at the molecular imaging level.
