Objective:To investigate the correlation between serum ferritin (SF) level and liver damage in the acute stage of dengue fever.Methods:A retrospective study was conducted to analyze 171 cases diagnosed with dengue fever as dengue fever group and 130 healthy patients as control group in Hangzhou 3A grade hospital from July to December 2017. Clinical data, SF and liver function related indicators were collected from both groups: alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) to analyze the correlation between liver damage and SF in patients with dengue fever.Results:ALT, AST, and SF levels were significantly higher in the dengue fever group than those in the healthy control group ( Z = 11.553, 15.054 and 15.163, P < 0.001). SF levels were higher in the dengue fever combined with liver damage group than those without the liver damage group ( z = 6.930, P < 0.001). However, there was no statistically significant differences in age, gender, peak body temperature, and history of liver disease ( P > 0.05). In addition, Spearman’s correlation analysis showed that SF was positively correlated with ALT, AST, and TBIL ( r = 0.464, 0.531 and 0.315, P < 0.001). Among dengue patients with different SF levels, there were significant difference in ALT, AST levels and incidence of liver damage ( H = 14.240 and 17.584, χ2 = 49.547, P < 0.001). Patients with higher SF levels had higher ALT, AST levels and incidence of liver damage. Binary logistic regression analysis showed that hyperferritinemia (SF≥500 ng/ml) was the risk factor for dengue fever combined with liver damage ( OR = 8.120, P < 0.001). Furthermore, ROC curve analysis showed that the AUC for SF to judge dengue fever combined liver damage was 0.846 (95% CI: 0.785-0.908), and the sensitivity and specificity when the SF cut-off value was 1 506 ng/ml were 74.8% and 83.3%. Conclusion:There is a certain correlation between the SF level and the degree of liver damage in acute stage of dengue fever patients, and hyperferritinemia is a risk factor for dengue fever combined with liver damage.

Anhedonia is the loss of pleasure or lack of reaction to pleasurable stimuli, which is a promising phenotype of depression. In order to explore the potential biological mechanism, the recent ad?vances were summarized from researches focused on depression with anhedonia from neuroanatomy,inflamma?tion and immunology,and molecular genetics. The structural and functional brain imaging showed that the ac?tivity in reward?related brain regions of the depressive disorder with an anhedonia was changed during re?ward?related tasks.In addition,some other genetic studies based on the related neurotransmitter,such as do?pamine, together with the findings from the researches on immunological inflammation, may shed light on finding the potential targets for novel antidepressants,besides the 5?HT.

Objective: Study the clinical significance of HBX gene detection, sequence analysis in peripheral blood mononuclear cell(PBMC) of chronic hepatitis B(CHB) patients with serum HBV DNA negative conversion after treatment by nucleoside analogues(NAs). Methods: Detected and analyzed the HBX gene sequence by real time PCR in PBMC of 60 patients with CHB including some with cirrhosis or hepatocellular carcinoma(HCC), all the serum HBV DNA had turned negative after treatment by NAs, and explore the clinical significance of the HBX gene. Results: HBX genes were detected in 37 cases(61.67%, 37/60). HBX positive rates of PBMC in HCC and cirrhosis patients were higher than that of CHB patients(P=0.000, P=0.010). HBX △120, HBX△129, HBX△131 truncations were detected in two HCC and one CHB cases. Two hotspot mutation including A389T/G391A, T380C had been found, and A389T/G391A double mutation in HCC patients was significantly higher than that in CHB patients(P=0.021). In cirrhosis and HCC patients, T380C mutation rate in HBeAg(-) cases was higher than that in HBeAg(+ ) cases(P=0.035). Conclusions In patients with serum HBV DNA negative conversion after treatment by NAs, PBMC HBX gene positive rates in cirrhosis or HCC cases are higher than that in CHB cases. A389T/G391A double mutation rate in HCC cases is significantly higher than that in CHB cases. In cirrhosis and HCC patients, T380C mutation rate in HBeAg(-) cases is higher than that in HBeAg(+ ) cases.

Objective To investigate the clinical effect of paraquat (PQ) detoxification recipe combined with continuous hemoperfusion (HP) in the treatment of patients with acute paraquat poisoning (APP) and clinical significance of soluble CD14 subtype (sCD14-st, Presepsin). Methods A prospective randomized controlled trial was conducted. 152 patients with moderate APP admitted to Department of Emergency Medicine of Harrison International Peace Hospital Affiliated to Hebei Medical University from July 2013 to June 2017 were enrolled, and they were randomly divided into three groups. The patients in HP group (group A, n = 35) only received 2-hour HP for 3 times, 8 hours each time, those in PQ detoxification recipe combined with HP group (group B, n = 50) received PQ detoxification recipe 1 (once per 2 hours until no PQ component was found in faeces) and 2 (3 times a day for 14 days) beside HP. The others in PQ detoxification recipe combined with persistent HP group (group C, n = 67) received continuous HP until the PQ component in serum was not detected. The parameters of organ function and inflammatory factor, and blood Presepsin and PQ contents were determined before and after treatment. The curative effect and 28-day mortality were recorded. The correlations between serum Presepsin level and PQ content as well as 28-day mortality were analyzed with Pearson correlation analysis. Receiver operating characteristic curve (ROC) was plotted to analyze the predictive value of Presepsin on prognosis. Results The total effective rate of group C was significantly higher than that of groups A and B [70.1% (47/67) vs. 34.3% (12/35), 54.0% (27/50)], and 28-day mortality was significantly lowered [29.8% (20/67) vs. 65.7% (23/35), 46.0% (23/50), both P < 0.05]. There was no significant difference in alanine aminotransferase (ALT), MB isoenzyme of creatine kinase (CK-MB), serum creatinine (SCr), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), and interleukins (IL-6 and IL-10) before treatment among the three groups. Five days after treatment, the above parameters in the three groups were increased as compared with those before treatment, but the increase degree in group C was the lowest. At 7 days after treatment, the parameters were decreased, especially in group C. There was no significant difference in serum Presepsin and PQ levels before treatment among the three groups. With the prolongation of treatment time, the Prespsin levels in groups A, B, and C were increased, and peaked at 12 hours (μg/L: 4.28±0.20, 3.87±0.25, 3.53±0.23), then gradually decreased,and the PQ contents were lower than those before treatment from 8 hours (mg/L: 1.76±0.12 vs. 2.12±0.17, 1.57±0.08 vs. 2.24±0.16, 1.25±0.10 vs. 2.14±0.18), with a time dependence pattern, especially in group C (all P < 0.05) . Correlation analysis showed that blood Presepsin level was positively correlated with PQ content and 28-day mortality (r1= 0.917, r2= 0.864, both P = 0.001), suggesting that the higher the PQ content was, the higher the Presepsin level, and the higher the 28-day mortality was. ROC curve analysis showed that the area under ROC curve (AUC) of Presepsin predicting 28-day mortality was 0.863; when the cut-off value was 1.22 μg/L, the sensitivity was 83.3%, the specificity was 81.4%, the positive predictive value was 77.46%, and the negative predictive value was 86.42%. Conclusions Early administration of PQ detoxification recipe combined with continuous HP treatment can effectively reduce Presepsin level, decrease the mortality of patients with moderate APP, improve the prognosis. Presepsin can assess the prognosis of patients with APP.

Objective To compare the difference of the sense of security and social support between left-behind women and non left-behind women in rural area.Methods Social Support Rating Scale (SSRS) and security questionnaire(SQ) were used to measure social support and sense of security of 98 left-behind women and 151 non left-behind women.The data was analyzed by SPSS17.0.Results ①In the social support rating,compared with the non left-behind women,the left-behind women has lower score in the total score((40.561±6.692) vs (59.722±8.699),t=18.530),determining the control factor((21.459±3.891) vs (30.013±4.950),t=14.450) and human security factor((19.102±3.737) vs (29.709±4.849),t=18.392) and the differences were statistical significant(all P＜0.05).②In the social support rating scale,left-behind women had lower scores in total score,exploitation degree of support,subjective support and objective support than the left-behind women(all P＜0.05).③The total score and each factor score of security scale,and the total score and each factor score of social support rating scale in the left-behind women showed significantly positively correlated(r=0.245-0.507,P＜0.05).Conclusion The sense of security and social support of the left behind women were worse than that of non left-behind women.It is necessary to carry out psychological intervention for them.

OBJECTIVETo study the clinical significance of hepatitis B surface antigen (HBsAg) levels and HBsAg/hepatitis B virus (HBV) DNA ratio in relation to liver inflammation in HBeAg-positive chronic hepatitis B (CHB).

METHODSOne hundred and fifty-three Chinese patients with chronic HBV infection with HBeAg-positive status were enrolled in the study.Quantitative measurements were made for HBsAg levels by immunoassay (Architect HBsAg QT by Abbott Diagnostic) and HBV DNA by real-time fluorescence quantitative PCR.Levels of liver function markers were measured by standard methods.Liver biopsy specimens were obtained from all patients and used to score the histology (liver inflammation) activity index (HAI) and grade (G) the extent of necroinflammation.Statistical correlation analysis was performed to determine the association of HBsAg titre or HBsAg/HBV DNA ratio with the various parameters of liver injury.

RESULTSHBsAg titre and HBsAg/HBV DNA ratio were significantly correlated (r =0.578, P less than 0.0001).A significant positive correlation (r =0.642, P less than 0.0001) was found between HBsAg titre and HBV DNA load, and a significant negative correlation was found between the HAI and HBsAg (r =-0.389, P less than 0.0001) and HBsAg/HBV DNA ratio (r =-0.307, P=0.000l).A significant positive correlation was found between alanine aminotransferase (ALT) level and the HAI (r =0.480, P less than 0.0001).Patients with G less than 2 necroinflammation had significantly higher HBsAg titre and HBsAg/HBV DNA ratio than patients with G more than or equal to 2 necroinflammation (both P less than 0.01) but similar levels ofHBV DNA.Generation of a receiver operating characteristic curve using G more than or equal to 2 as the positive index provided the following area under the curve (AUC) values:HBsAg titre, 0.700; HBsAg/HBV DNA ratio, 0.672; ALT level, 0.713.When the random chance AUC was 0.5, all levels of AUC were statistically significant (Pless than 0.001).HBsAg titre (sensitivity =76.92%) was more sensitive than ALT level (sensitivity =76.92%), and HBsAg/HBV DNA ratio (specificity =81.33%) was more specific than ALT level (specificity =81.33%).Youden's index for comprehensive evaluation using ALT was higher than those for HBsAg titre or HBsAg/HBV DNA ratio.When HBsAg and ALT were considered in parallel, the sensitivity increased to 94.08% and specificity rose to 85.60%.

CONCLUSIONHBsAg titre, HBsAg/HBV DNA ratio and ALT levels can be used as the index for judging the degree of liver inflammation in HBeAg-positive CHB patients.Higher sensitivity and specificity are attained when HBsAg and ALT are used in series or parallel.
