RESUMEN
Aim To explore the efficacy of levosimendan on hypoxia pulmonary hypertension through animal experiments, and to further explore the potential mechanism of action using network pharmacological methods and molecular docking technique. Methods The rat model of hypoxia pulmonary hypertension was constructed to detect right heart systolic pressure and right heart remodeling index. HE , Masson, and VG staining were core targets were screened out. GO and KEGG pathway enrichment analysis were performed using the DAVID database. Molecular docking of the core targets was performed with the AutoDock software. Results The results of animal experiments showed that levosimendan had obvious therapeutic effect on hypoxia pulmonary hypertension. The network pharmacology results showed that SRC, HSP90AA1, MAPK1, PIK3R1, AKT1, HRAS, MAPK14, LCK, EGFR and ESR1 used to analyze the changes of rat lung histopathology. Search the Swiss Target Prediction, DrugBank Online, BatMan, Targetnet, SEA, and PharmMapper databases were used to screen for drug targets. Disease targets were retrieved from the GeneCards, OMIM databases. The "drug-target-disease" network was constructed after identification of the two intersection targets. The protein interaction network was constructed and the were the key targets to play a therapeutic role. Molecular docking showed good docking of levosimendan with all the top five core targets with degree values. Conclusions Levosimendan may exert a therapeutic effect on hypoxia-induced pulmonary hypertension through multiple targets.
RESUMEN
ObjectiveTo genotype Oncomelania hupensis, based on microsatellites, in different snail-bearing environments in Jiaxing City, Zhejiang Province, for population genetics analysis in order to explore the reasons and influencing factors for the existence or proliferation of snails and to provide scientific basis for effective monitoring and control of snails. MethodsA total of 90 snail samples from three populations were collected in Yaobang Village (YB) and Sanxing Village (SX) in Pinghu City, and Yunhe Farm (YH) in Xiuzhou District, all were selected for snail checking in key snail habitats of Jiaxing City in 2022. DNA of the snails was genotyped and analyzed for population genetics using nine microsatellite loci. ResultsA total of 84 alleles were observed, and the mean number of alleles (Na) was 7.889, 5.667, and 3.778 for YB, SX, and YH respectively; the number of effective alleles (NeA) was 4.807, 3.329, and 2.294, respectively; and the coefficients of inbreeding (FIS) were 0.400, 0.377, and 0.493, respectively. Under the Infinite Allele Model (IAM), the SX and YH might have a recent bottleneck. The NEstimator and LDNe software calculated effective population sizes (Ne) were above 31.9. AMOVA analysis showed that the variation of snails in the three populations mainly existed among individuals, accounting for 41.4% of the total variation. The value of the index of genetic differentiation between populations (FST) was 0.286, indicating a high degree of genetic differentiation. The results of the principal component analysis and phylogenetic tree were consistent, and the three populations were divided into two lineages, YB and SX were one lineage, and YH belonged to another independent lineage. Population history and dynamics analysis showed that the gene flow of the three populations was insufficient, population divergence history indicated that YH might have diverged from SX first, and YB was produced by the contact fusion of SX and YH. ConclusionThe genetic diversity of snail populations in Jiaxing City is generally low, and the snail populations are unstable, with a great degree of genetic differentiation and insufficient gene flow among populations. This study can provide a basis for evaluating the effectiveness of the control of the snail as well as monitoring the trend of the spread of the snail.
RESUMEN
Phytoestrogens, such as isoflavones, are known for their capacity to simulate various physiological impacts of estro‑ gen in the human body. Our research evaluated the effects of isoflavone-enriched soybean leaves (IESL) on collagen fiber loss prompted by ovariectomy in Sprague Dawley (SD) rats, thereby simulating menopausal changes in women.IESL, bolstered with an increased concentration of isoflavones through a metabolite farming process, contained a significantly higher amount of isoflavones than regular soybean leaves. Our results indicate that the administration of IESL can counteract the decrease in relative optical density and dermal thickness of collagen fibers caused by ova‑ riectomy in SD rats, with more pronounced effects observed at higher isoflavone dosages. These outcomes suggest that soybean leaves rich in isoflavones may hold potential benefits in combating collagen degradation and skin aging symptoms related to menopause. Further research is needed to fully understand the exact molecular pathways at play and the potential clinical relevance of these findings.
RESUMEN
Objective:To investigate the abnormal changes of the nodal centrality of the whole-brain network in patients with narcolepsy type 1 (NT1) through the degree centrality (DC) technique of resting-state magnetic resonance and the predictive value for NT1.Methods:From September 2019 to November 2021, 18 NT1 patients who were first diagnosed and never accepted managements and 18 age-, sex-matched healthy controls recruited by advertisement in the Second Affiliated Hospital of Nanchang University were required for resting-state functional magnetic resonance imaging scans and clinical scale assessment, including Epworth Sleepiness Scale (ESS), Self-rating Anxiety Scale, Self-rating Depression Scale, Pittsburgh Sleep Quality Index, Insomnia Severity Scale and Multidimensional Fatigue Inventory-20 (MFI-20). The differences in DC values between the NT1 patients and healthy controls were analyzed using the DC method. Then, the correlation between DC values in differential brain regions and clinical characteristics of NT1 was explored through Pearson correlation analysis. The receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive value of the DC values in the differential brain regions for NT1 patients.Results:Compared with the healthy controls, the DC value of the right superior temporal gyrus was increased, while the DC values of the bilateral middle frontal gyrus and the right precuneus were decreased in the NT1 patients (all P<0.05, Gaussian random-field correction). The DC value of the right superior temporal gyrus in the NT1 patients was positively correlated with the ESS score ( r=0.82, P<0.001) and MFI-20 score ( r=0.48, P=0.040). The DC value of the right middle frontal gyrus was positively correlated with the disease course ( r=0.51, P=0.032). The ROC curve showed that the area under the curve of NT1 predicted by the DC value of the right superior temporal gyrus was 0.95. And the areas under the curve of non-NT1 predicted by the DC values of the left middle frontal gyrus, right middle frontal gyrus, and right precuneus were 0.86, 0.84 and 0.87, respectively. Conclusions:NT1 patients have abnormal resting-state DC in the default network, executive network core brain regions, and superior temporal gyrus. And the DC value in the right superior temporal gyrus may be a potential biomarker of NT1 patients.
RESUMEN
Type 1 narcolepsy is a rare central nervous system disorder that is believed to result from the interaction of environmental and genetic factors. Traumatic brain injury (TBI) is one of the most common causes of secondary narcolepsy. Currently, there are very few reports on post-TBI narcolepsy, and this patient is the first reported case of HLA-DQB1 *06:02-positive type 1 narcolepsy following TBI in China. The clinical data of this patient are retrospectively analyzed to improve the understanding of the diagnosis and pathogenesis of the disease among clinicians.
RESUMEN
AIMS: To evaluate the efficiency of ultrasonic spleen thickness (UST), routine variables and (expanded) Baveno VI criteria for high-risk gastroesophageal varices (HRGOV) detection in cirrhotic patients. METHODS: In total, 305 cirrhotic patients were retrospectively enrolled in the deriving cohort and 328 cirrhotic patients with hepatitis B sustained viral response were prospectively enrolled in the validation cohort. HRGOV was defined as medium and severe gastroesophageal varices (GOV), mild GOV with red signs or Child-Pugh C. The cut-offs for HRGOV were determined by likelihood ratio indicating strong evidences. Algorithms of Spleen thickness-Age-Liver stiffness measurement (LSM, by Fibroscan®)-Albumin (SALA) and Spleen thickness-Platelet-Albumin (SPA) were derived by multivariate analyses. RESULTS: The area under receiver operating characteristics curve of SALA, SPA, UST, platelet, and LSM were 0.849, 0.835, 0.808, 0.746, and 0.655 in the deriving cohort, and improved to 0.901, 0.904, 0.858, 0.876, and 0.811 in the validation cohort, respectively. While SALA, SPA, UST, platelet, Baveno VI criteria (BVI), and expanded BVI spared 46.6%, 38.0%, 29.2%, 21.0%, 12.1%, and 23.6% esophagogastroduodenoscopy in the deriving cohort, these numbers were improved to 68.1%, 66.8%, 27.1%, 37.8%, 36.0%, and 61.0% in the validating cohort, respectively; however, the negative likelihood ratio of expanded BVI was up to 0.16. SPA spared less esophagogastroduodenoscopy than SALA, which can be supplemented by stepwise applying UST and SPA. Sequentially combining UST and SALA, BVI and SALA exempted additional 10-5% endoscopies. CONCLUSIONS: SPA, without LSM, improves HRGOV detection comparing with BVI. UST based algorithms combination can achieve the best efficiency especially in sustained virus response hepatitis B.

BACKGROUND AND OBJECTIVE: Prostate cancer (PCa) is one of the most common malignant tumors in men. Geriatric Nutritional Risk Index (GNRI) is an objective index for evaluating nutritional status of elderly people over 65 years old. The aim of the current study was to explore the correlation and predictive value between GNRI and postoperative recovery and complications in PCa patients undergoing laparoscopic radical prostatectomy (LRP). METHODS: Taking 98 as the GNRI boundary value, 96 PCa patients (aged≥65 y) undergoing LRP in the Department of Urology, Affiliated Hospital of North Sichuan Medical College from January 2018 to December 2020 were grouped into malnutrition group (MNg, 34 patients, 35.4%) and normal nutrition group (NNg, 62 patients, 64.6%). Basic information, laboratory examination indexes, operation conditions, postoperative complications and postoperative recovery indexes of patients were recorded and retrospectively analyzed. Clavien-Dindo Classification System (CDCS) was used to assess postoperative complications. T-test was used to analyze differences between the two groups. ROC curve was generated to determine the predictive value of GNRI for postoperative complications. RESULTS: Percentage of complications was significantly higher in MNg group compared with that in NNg group (P < 0.01). The average grade based on CDCS was significantly lower in NNg group compared with that in MNg group (P < 0.01). Body weight, Body Mass Index (BMI), preoperative hemoglobin value (HGB), serum albumin (ALB) values of MNg and NNg were significantly positively correlated with GNRI (P<0.01). Incidence and severity of postoperative complications of MNg patients were significantly higher compared with those of NNg patients (P<0.05). Average hospitalization cost of MNg patients was higher in MNg patients compared with that of NNg patients (P<0.05). Duration of post-anesthesia care unit (PACU), duration of antibiotic use and duration of indwelling drainage tube were longer in MNg patients compared with those in NNg patients (P<0.05). Furthermore, volume of indwelling drainage tube was higher in MNg patients compared with that in NNg patients (P<0.05). CONCLUSION: GNRI is an effective and reliable tool for evaluation of preoperative nutritional status of prostate cancer patients. The findings showed that GNRI is correlated with postoperative recovery and complications, and is an effective predictive marker.

BACKGROUND: Quantitative data are limited on the natural course of liver fibrosis in patients with chronic HBV infection (CHB). AIMS: To estimate the prevalence of fibrosis status including non-fibrosis, significant fibrosis, advanced fibrosis, and cirrhosis throughout the natural course of CHB. METHODS: We searched Cochrane library, EMBASE, PubMed, SCOPUS, Web of Science, and ScienceDirect from January 1993 to November 2019 for studies with histologic data on liver fibrosis in CHB natural course. CHB course was defined based on current criteria for identifying infection phases as recommended by international clinical practice guidelines, including the HBeAg-positive immune-tolerant, HBeAg-positive immune-active, HBeAg-negative immune-inactive, HBeAg-negative immune-reactive, and HBsAg-negative phases. Pooled prevalence rate of fibrosis status at each phase was obtained from random-effect meta-analyses. RESULTS: Thirty-three studies with 9,377 adult participants (23.8-49.0 age years; 45.5-88.6% males) were eligible and finally included. The estimated prevalence of non-fibrosis, significant fibrosis, advanced fibrosis, and cirrhosis was, for HBeAg-positive immune-tolerant phase: 31.2% (95%CI 15.6-46.7), 16.9% (95%CI 7.8-26.1), 5.4% (95%CI 0.0-11.2), and 0.0% (95%CI 0.0-1.5); HBeAg-positive immune-active phase: 6.9% (95%CI 3.6-10.2), 50.6% (95%CI 39.2-61.9), 32.1% (95%CI 24.2-40.0), and 12.8% (95%CI 8.6-17.0); HBeAg-negative immune-inactive phase: 32.4% (95%CI 0.0-100.0), 24.8% (95%CI 4.5-45.1), 3.0% (95%CI 0.0-8.3), and 0.0% (95%CI 0.0-1.0); and HBeAg-negative immune-reactive phase: 6.3% (95%CI 3.5-9.2), 50.3% (95%CI 38.9-61.7), 30.3% (95%CI 20.9-39.6), and 10.0% (95%CI 6.6-13.5), respectively. There was only one study for HBsAg-negative phase, thus not allowing further meta-analyses. CONCLUSIONS: Fibrosis risk persists through CHB natural course. These data can support risk estimation in clinical practice and provide reference for noninvasive investigation.

Objectives: To examine the impact of probiotics on the lung development of preterm birth of Bama pig. Methods: From April 2020 to October 2021, this animal experimental research was performed by setting up preterm (birth at gestation 104 d), full-term (birth at gestation 113 d), preterm with probiotics (birth at gestation 104 d treated with probiotics given at 3 d after birth), and full-term with probiotics (birth at gestation 113 d treated with probiotics given at 3 d after birth) groups and using the preterm Bama minipig model, the body weights were recorded and lung, ileum, and intestinal content samples were collected at birth, 4 days, 9 days, and 21 days after births of the piglets in preterm and full-term groups, the same samples were collected on 9 days after births of the piglets in preterm with probiotics and full-term with probiotics groups. The body weight and radial alveolar counts (RAC) were compared to evaluate the lung development of the piglets. The lengths of ileal villus were compared to evaluate the development of ileum. The composition structures of bacteria in ileum were analyzed by 16 S rRNA sequencing. The statistical analyses between different groups were performed by t test. Results: There were totally 30 piglets (16 female piglets and 14 male piglets) involving 12 piglets in preterm and full-term groups respectively and 3 piglets in preterm with probiotics and full-term with probiotics groups respectively. The body weights of the piglets in preterm group were lower than those in full-term group at 4, 9 and 21 d after birth ((507±27) vs. (694±56) g, (620±35) vs. (1 092±154) g, (1 660±210) vs. (2 960±418) g,t=2.96, 2.99, 2.78, all P<0.05). The alveolarization of the preterm piglets at 9 days after birth was significantly lower than that of the full-term piglets at the equivalent time point (4.00±0.29 vs. 6.11±0.35, t=4.64, P<0.01). The bacteria genus with the highest abundance in ileum were all different between the preterm and the full-term groups at 4, 9 and 21 d after birth (4 d Escherichia-Shigella (26.63%) and Enterococcus (30.48%) respectively;9 d Turicibacter (35.94%) and Lactobacillus (27.33%) respectively;21 d Escherichia-Shigella (28.02%) and Lactobacillus (46.29%) respectively). The heights of ileal villus of the preterm piglets at 9 d after birth were significantly lower than those of the full-term minipigs at the equivalent time point ((297±21) vs. (411±32) μm, t=3.01, P=0.007).There were both no differences in the body weight and alveolarization ((692±36) vs. (767±67) g, 5.44±0.34 vs. 5.89±0.26, t=0.74, 1.04, both P>0.05) between the piglets in preterm with probiotics group and those in full-term with probiotics group. Turicibacter was the dominant genus in the piglets of both preterm with probiotics and the full-term with probiotics groups. The heights of ileal villus of the piglets in preterm with probiotics group were significantly longer that those of the piglets in preterm group ((371±13) vs. (297±21) μm, t=3.04, P=0.006), and were both not significantly different from those of the piglets in full-term with probiotics group and full-term group ((371±13) vs. (338±12) and (411±32) μm, t=1.90, 1.15, both P>0.05). Conclusions: Premature birth could impact the lung alveolarization of piglets. The probiotics could improve the lung alveolarization of preterm minipigs by promoting the development of ileum.

This study aims to evaluate the predictive value of the prognostic nutritional index (PNI) and albumin-bilirubin grade (ALBI) for the postoperative prognosis of hepatitis B virus-associated hepatocellular carcinoma (HBV-HCC) patients undergoing radical hepatectomy (RH). Besides, we seek to identify novel prognosis indicators for HBV-HCC patients. Between April 2009 and March 2015, this work enrolled 868 patients diagnosed with HBV-HCC and undergoing RH in the Liver Surgery Department, West China Hospital, Sichuan University (WCHSU). The basic information, laboratory examination indicators, pathological reports, and follow-up data of patients were included. SPSS 22.0 statistical software was used for statistical data analyses. Platelet (PLT), alpha-fetoprotein (AFP), maximum diameter (max-D), number of tumors (Number), degree of differentiation (DD), Microvascular invasion situation (MVI), satellite focus situation (SF), PNI, and ALBI were the independent risk factors for both overall survival (OS) and disease-free survival (DFS) of HBV-HCC patients undergoing RH. Taking PNI = 46 and ALBI = - 2.80 as cut-off values, the OS and DFS of the PNI-high group were significantly higher than those of the PNI-low group. Meanwhile, the OS and DFS of the ALBI-low group were significantly higher than those of the ALBI-high group; the OS and DFS of the PNI-high + ALBI-low group were significantly higher than those of the PNI-low + ALBI-high group. Xie prognostic index (XPI) was the independent risk factor for both OS and DFS of HBV-HCC patients undergoing RH. The OS and DFS of the XPI-high group were significantly higher than those of the XPI-low group. This paper reveals that preoperative PNI and ALBI can predict the OS and DFS of HBV-HCC patients undergoing RH. Their impact on the prognosis of HBV-HCC patients is insignificant, however, it cannot be ignored. XPI can precisely predict the prognosis of HBV-HCC patients undergoing RH, nonetheless, its effect requires additional research for validation.

OBJECTIVES: We performed an updated meta-analysis to clarify the relationship between the CEBPE rs2239633 polymorphism and the childhood acute lymphoblastic leukemia (CALL) susceptibility. METHODS: All the case-control studies were updated on October 5, 2020, through Web of Science, PubMed, Cochrane Library, Embase, and China National Knowledge Infrastructure (CNKI) electronic database. The heterogeneity in the study was tested by the Q test and I2, and then the random ratio or fixed effect was utilized to merge the odds ratios (OR) and 95% confidence interval (CI). We also performed sensitivity analysis to estimate the impact of individual studies on aggregate estimates. Publication bias was investigated by using funnel plot and Egger's regression test. All statistical analyses were performed using Stata 12.0. RESULTS: A total of 20 case-control studies were selected, including 7014 patients and 16,428 controls. There was no association of CEBPE rs2239633 polymorphism with CALL (CC vs CT + TT: OR = 1.08, 95% CI = 0.94-1.26; CC + CT vs TT: OR = 1.10, 95% CI = 0.94-1.30; C vs T: OR = 1.02, 95% CI = 0.92-1.13). In the subgroup analysis by ethnicity, there is no significant association of this polymorphism and CALL risks among Asian and Caucasian populations in the three genetic models (CC vs CT + TT, CC + CT vs TT, and C vs T). CONCLUSION: This meta-analysis found no significant association between the CEBPE rs2239633 polymorphism and susceptibility to CALL.

Aim To identify differentially expressed microRNAs (miRNAs) in rat myocardial infarcted tissues and predict their interaction with IncRNAs and target genes, as well as to explore potential pathophysiology mechanisms in myocardial infarction. Methods A rat model of myocardial infarction was established by ligating the left anterior descending coronary artery. Trizolwas used to extract total RNA from infarcted myocardial area for microarray detection. Bioinformatics methods were used to predict interaction IncRNAs, target genes, and functional enrichment of miRNAs thatwere significantly differently expressed. The possible IncRNA-miRNA-mRNA regulatory networks were identified finally. Results The elevation of ST segment of ECG showed that the rat model of myocardial infarction was successfully prepared. Microarray results showed that there were 19 significantly differently expressed miRNAs. Eight of these miRNAs (miR-21, miR-132, miR-222, miR-223-3p, miR-146a/b, miR-181b, miR-449a-5p, miR-122) were proven to be myocardial infarction treatment candidates. Whether seven miR-NAs (miR-365-5p, miR490-5p, miR-6333, miR-30cl-3p, miR-3591, miR-3596c, miR-877) were related to myocardial infarction called for further confirmation. There might be several new IncRNA-miRNA-mRNA mechanisms in the development of myocardial infarction. ENSRNOT00000076620-miR-146b-5p-STAT3/Rnf7/Qrsll may be involved in the process of cardiomyocyte apoptosis and mitochondrial damage during myocardial infarction. ENSRNOT00000071991-miR-122-Deptor might inhibit the autophagy of cardiomyocytes and exacerbate myocardial infarction. Conclusions The ternary relationship of IncRNA-miRNA-mRNA obtained in this study may provide possible research directions and a certain theoretical basis for further exploration of the molecular level pathological mechanism of myocardial infarction, and new therapeutic targets for myocardial infarction as well.

Objective To analyze the diagnosis and treatment of two imported cases with schistosomiasis haematobia, so as to provide insights into improving the diagnosis and treatment and avoiding misdiagnosis and mistreatment of imported schistosomiasis haematobia. Methods The medical records and epidemiological data pertaining to the two cases were collected. The stool and urine samples were collected for identification of Schistosoma eggs using the Kato-Katz technique and direct smear method after centrifugal precipitation, and blood samples were collected for detection of anti-Schistosoma antibody. Following definitive diagnosis, the patients were given praziquantel therapy. Results The patient 1, a Malagasy, was infected in Madagascar and returned to China for delivery. The case presented intermittent painless terminal hematuria symptoms, and showed no remarkable improvements following multiple-round treatments in several hospitals. In January 2017, she was found to be positive for anti-Schistosoma antibody, negative for feces test, and positive for S. haematobium eggs in urine test, and miracidia were hatched from eggs. Then, the case was diagnosed as schistosomiasis haematobia. Patient 2 worked in Republic of Malawi for many years, and presented intermittent painless terminal hematuria since October 2018; however, no definite diagnosis or effective treatment was received after admission to multiple hospitals. In March 2019, pathological examinations showed a number of eggs in the interstitium of the bladder mass, accompanied by a large number of eosinophils, which was consistent with schistosomiasis cystitis. In April 2019, he was tested positive for serum anti-Schistosoma antibody, negative for the fecal test, and had S. haematobium eggs in urine samples, with miracidia hatched from eggs. Then, the case was diagnosed as schistosomiasis haematobia. Following treatment with praziquantel at a dose of 60 mg/kg, all symptoms disappeared. Conclusions Overseas imported schistosomiasis haematobia is likely to be misdiagnosed. The training pertaining to schistosomiasis control knowledge requires to be improved among clinical professionals, in order to avoid misdiagnosis and mistreatment.
RESUMEN
There have been recent extensive studies and rapid advancement on the pathogenesis underlying idiopathic pulmonary fibrosis (IPF), and intricate pathogenesis of IPF has been suggested. The purpose of this study was to clarify the logical relationship between these mechanisms. An extensive search was undertaken of the PubMed using the following keywords: "etiology," "pathogenesis," "alveolar epithelial cell (AEC)," "fibroblast," "lymphocyte," "macrophage," "epigenomics," "histone," acetylation," "methylation," "endoplasmic reticulum stress," "mitochondrial dysfunction," "telomerase," "proteases," "plasminogen," "epithelial-mesenchymal transition," "oxidative stress," "inflammation," "apoptosis," and "idiopathic pulmonary fibrosis." This search covered relevant research articles published up to April 30, 2020. Original articles, reviews, and other articles were searched and reviewed for content; 240 highly relevant studies were obtained after screening. IPF is likely the result of complex interactions between environmental, genetic, and epigenetic factors: environmental exposures affect epigenetic marks; epigenetic processes translate environmental exposures into the regulation of chromatin; epigenetic processes shape gene expression profiles; in turn, an individual's genetic background determines epigenetic marks; finally, these genetic and epigenetic factors act in concert to dysregulate gene expression in IPF lung tissue. The pathogenesis of IPF involves various imbalances including endoplasmic reticulum, telomere length homeostasis, mitochondrial dysfunction, oxidant/antioxidant imbalance, Th1/Th2 imbalance, M1-M2 polarization of macrophages, protease/antiprotease imbalance, and plasminogen activation/inhibition imbalance. These affect each other, promote each other, and ultimately promote AEC/fibroblast apoptosis imbalance directly or indirectly. Excessive AEC apoptosis and impaired apoptosis of fibroblasts contribute to fibrosis. IPF is likely the result of complex interactions between environmental, genetic, and epigenetic factors. The pathogenesis of IPF involves various imbalances centered on AEC/fibroblast apoptosis imbalance.

The detection rate of boys (2.2%) was higher than that of girls (0.8%). The difference was statistically significant ( χ 2=26.51, P <0.01). Among 126 hyperactive children, 40(31.7%)had another type of behavior problem, and 82(65.1%)had two or more additional behavior problems. The results of Logistic regression analysis showed that boy( OR =2.85, 95% CI =1.88-4.30), sleep deprivation( OR =1.87, 95% CI =1.31-2.68), occupation of mother being farmer or otherwise( OR =1.81, 95% CI =1.11-2.94) were associated with more hyperactivity behavior. While, living with parents in the past six months ( OR =0.61, 95% CI =0.40-0.92) was associated with less hyperactivity behavior( P <0.05).@*Conclusion@#Early intervention of preschool children s behavior problems should focus on boys, maintain reasonable sleep time and increase parental care.
RESUMEN
The performances of routine tests such as FIB-4 and APRI in detecting cirrhosis and significant fibrosis in chronic hepatitis B (CHB) have been shown to be discrepant between studies. Novel tests such as red cell distribution width-platelet ratio (RPR), γ-glutamyl transpeptidase to platelet ratio (GPR) and easy liver fibrosis test (eLIFT) are introduced recently. To evaluate the aminotransferase influence on the performance of these routine tests, a total of 1005 CHB patients who underwent liver biopsies and routine tests were retrospectively analysed. The diagnostic cut-offs referring to likelihood ratio were determined for excluding or including cirrhosis diagnosis and also for ruling in significant fibrosis diagnosis. The performances of RPR, FIB-4, eLIFT and APRI in detecting cirrhosis seemed improved at higher ALT levels, while GPR was conversely impaired. The likelihood ratio was â for APRI cut-off 2 diagnosing cirrhosis in ALT < 2 upper limit of normal (ULN), 14.6 for APRI cut-off 1.5 determining significant fibrosis in ALT ≤ 5ULN and 20.6 for FIB-4 cut-off 3.2 diagnosing ≥ F3 in the total cohort, respectively. The optimal cut-offs for cirrhosis diagnosis were increased with higher ALTs by tests which included aminotransferase, but not for RPR. The proportions of patients classified as having cirrhosis or no cirrhosis stratified by ALT level cut-offs were superior. Stepwise applying RPR, GPR and eLIFT would determine 60% of patients as having cirrhosis or no cirrhosis with an accuracy of 93.0%. In conclusion, the performance of aminotransferase comprising tests in detecting cirrhosis in CHB were influenced by ALT levels. Thus, ALT stratified cut-offs may be a preferred alternative. In resource-limited settings, stepwise applying routine tests could be recommended as a preferred measurement for cirrhosis detection.

OBJECTIVE: This study is aimed at determining the preoperative nutritional status of patients with hepatic alveolar echinococcosis (HAE), and subsequently establish a concise and reasonable nutritional evaluation indicator. The established evaluation method could be used for clinical preoperative risk assessment and prediction of post-operation recovery. METHODS: The basic patient information on height, body weight, BMI and hepatic encephalopathy of 93 HAE patients were examined. Subsequently, abdominal ultrasonography, blood coagulation and liver function tests were done on the patients. Liver function was assessed using the Child-Pugh improved grading method while nutritional status was evaluated using the European Nutrition Risk Screening 2002 (NRS 2002) method. Additional parameters including hospitalization time, the hemoglobin (HGB) level on the 3rd day after the operation, and the number of postoperative complications of HAE patients were also recorded. RESULTS: The NRS 2002 score was negatively correlated with body weight, body mass index (BMI)and albumin (ALB) (P<0.01), and positively correlated with the transverse and longitudinal diameters of the lesions (P<0.01). A worse grading of liver function was associated with a low ALB and a high NRS 2002 score (P<0.01). Results of the NRS 2002 score indicate that the hospitalization time of the normal nutrition group was significantly shorter than that of the malnourished group (P < 0.05). The HGB level of the control group on the 3rd day after the operation was significantly higher than that of the malnourished group (P < 0.05), and the number of postoperative complications was lower than that of malnutrition group (P < 0.05). CONCLUSION: Malnutrition is common in HAE patients. The nutritional status of HAE patients is related to many clinical factors, such as Child-Pugh classification of liver function, size of the lesion, and ALB among others. Although both BMI and ALB can be used as primary screening indicators for malnutrition in HAE patients, NRS 2002 is more reliable and prudent in judging malnutrition in HAE patients. Therefore, BMI and ALB are more suitable for preoperative risk assessment and prediction of postoperative recovery.

Objective@#To evaluate ten year changes in deciduous teeth health and oral health behavior aged 5 year old children in Hainan province (during the year of 2005-2015), to provide basis for oral health promotion among 5 year old children in Hainan province.@*Methods@#Through the comparison and analysis of the third and the fourth national oral health epidemiology survey,changes of dental caries prevalence rate, dietary habit, oral health behavior, and health seeking behavior were analyzed.@*Results@#The prevalence of dental caries in 2005 was 76.1%, 2015 was 82.3% which had significant difference(χ2=6.23,P<0.05), the percentage of consuming sugary food and sweet drinks every day in 2005 was 13.4% and 6.1%, which increased to 30.0% and 7.4% respectively in 2015. The percentage of drinking milk and yoghurt with sugar was 47.6%, which decreased 36.5% in 2015 (χ2=12.76,P<0.05), the percentage of consuming sugary food and sweet drinks before going to bed in 2005 was17.8%, which decreased to 13.3% in 2015 (χ2=32.27,P<0.05). The percentage of brushing the teeth two or more times a day was 16.9%, which increased to 24.2% in 2015(χ2=20.50,P<0.05). The percentage of using fluoridated toothpaste decreased from 31.7% (2005) to 7.4% (2015) (χ2=229.13,P<0.05). No need to treatment for baby teeth and afraid of pain among children were the main reason for no health-seeking among parents which children of dental health problems,which deffered significantly between 2005 and 2015(χ2=6.05,9.34,P<0.05).@*Conclusion@#Children’s oral health behavior improved, while eating habits fluoridated toothpaste usage and health seeking behavior remain poor.Health education on child oral health should be strengthened.
