Abstract
Abstract The paternal inheritance characteristics of Y chromosome have been widely used in the forensic genetics field to detect the genetic markers in the non-recombining block, and used in the studies such as, genetic relationship identification, mixed stain detection, pedigree screen and ethnicity determination. At present, capillary electrophoresis is still the most common detection technology. The commercial detection kits and data analysis and processing system based on this technology are very mature. However, the disadvantages of traditional detection technology have gradually appeared with the rapid growth of bio-information amount, which promotes the renewal of forensic DNA typing technology. In recent years, next generation sequencing (NGS) technology has developed rapidly. This technology has been applied to various fields including forensic genetics and has provided new techniques for the detection of Y chromosome genetic markers. This article describes the current situation and application prospects of the NGS technology in forensic Y chromosome genetic markers detection in order to provide new ideas for future judicial practice.

Abstract
Myocardial ischemia is the main reason for ischemic heart diseases. Antioxidant treatment is considered as a possible approach to prevent myocardial ischemia injury, because oxidative stress is a key factor triggering it. This study was to investigate the protective effects of 3,5-dimethoxy-4-hydroxy myricanol (DHM) against oxidative stress-induced cytotoxicity on H9c2 cells and further explore its mechanisms. The oxidative stress and inflammatory response markers were detected by H2DCFDA fluorescent measurement, enzyme-linked immunosorbent assay (ELISA), real-time PCR and Western blot. Results showed DHM exerted inhibitory effects against H9c2 cell damage. Furthermore, DHM decreased oxidative stress in H9c2 cells through up-regulating protein expression of heme oxygenase-1 (HO-1) and nuclear factor (erythroid-derived 2)-like 2 (Nrf2). Moreover, DHM inhibited inflammatory responses through down-regulating the protein expression of mitogen-activated protein kinases (MAPKs) and nuclear factor kappa B (NF-κB). DHM exerted protective activities against oxidative stress-induced cell damage, at least through decreasing oxidative stress and inhibiting inflammatory responses, indicating that DHM have the potential to be developed as therapeutic agents for the treatment of myocardial ischemia.

Abstract
BACKGROUND Thrombospondin-related adhesive protein (TRAP) is a transmembrane protein that plays a crucial role during the invasion of Plasmodium falciparum into liver cells. As a potential malaria vaccine candidate, the genetic diversity and natural selection of PfTRAP was assessed and the global PfTRAP polymorphism pattern was described. METHODS 153 blood spot samples from Bioko malaria patients were collected during 2016-2018 and the target TRAP gene was amplified. Together with the sequences from database, nucleotide diversity and natural selection analysis, and the structural prediction were preformed using bioinformatical tools. RESULTS A total of 119 Bioko PfTRAP sequences were amplified successfully. On Bioko Island, PfTRAP shows its high degree of genetic diversity and heterogeneity, with π value for 0.01046 and Hd for 0.99. The value of dN-dS (6.2231, p < 0.05) hinted at natural selection of PfTRAP on Bioko Island. Globally, the African PfTRAPs showed more diverse than the Asian ones, and significant genetic differentiation was discovered by the fixation index between African and Asian countries (Fst > 0.15, p < 0.05). 667 Asian isolates clustered in 136 haplotypes and 739 African isolates clustered in 528 haplotypes by network analysis. The mutations I116T, L221I, Y128F, G228V and P299S were predicted as probably damaging by PolyPhen online service, while mutations L49V, R285G, R285S, P299S and K421N would lead to a significant increase of free energy difference (ΔΔG > 1) indicated a destabilization of protein structure. CONCLUSIONS Evidences in the present investigation supported that PfTRAP gene from Bioko Island and other malaria endemic countries is highly polymorphic (especially at T cell epitopes), which provided the genetic information background for developing an PfTRAP-based universal effective vaccine. Moreover, some mutations have been shown to be detrimental to the protein structure or function and deserve further study and continuous monitoring.

Abstract
Objective: To examine the correlations of C-reactive protein (CRP)/albumin ratio (CAR) with the postoperative complications of patients with colorectal cancer. Methods: The clinic data of 312 patients undergoing elective surgery for colorectal cancer in Hainan Hospital of People's Liberation Army General Hospital between January 2013 and July 2018 was analyzed retrospectively. There were 188 males and 124 females, aged (61.0±12.9) years (range: 21 to 86 years). Logistic analysis was used to identify relative factors for postoperative complications. Receiver operating characteristic curves were developed to examine the cutoff values and compare diagnostic accuracy of the CAR and CRP levels. Results: Postoperative complications occured in 28.5% (89/312) cases. Hemoglobin on postoperative day(POD) 3 (OR=0.977, 95% CI: 0.957 to 0.998, P=0.034), preoperative CRP (OR=1.209, 95% CI: 1.055 to 1.386, P=0.006) and CAR on POD 3 (OR=0.033, 95% CI: 0.016 to 0.067, P<0.01) were found to be significant independent relative factors for postoperative complications. The cutoff point of CAR on POD 3 was 0.325, patients with CAR≥0.325 were found to have more postoperative complications than those with CAR<0.325. The area under the curve of CAR on POD 3 and preoperative CRP were 0.872, 0.626, respectively. The positive predictive value of CAR on POD 3 was higher than that of preoperative CRP (79.9% vs. 55.1%). Conclusions: CAR is closely related to the occurrence of postoperative complications in colorectal surgery. Patients with CAR≥0.325 on POD 3 has higher incidence of postoperative complications.

Abstract
Although vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are under development, the antigen epitopes on the virus and their immunogenicity are poorly understood. Here, we simulate the 3D structures and predict the B cell epitopes on the spike (S), envelope (E), membrane (M), and nucleocapsid (N) proteins of SARS-CoV-2 using structure-based approaches and validate epitope immunogenicity by immunizing mice. Almost all 33 predicted epitopes effectively induce antibody production, six of these are immunodominant epitopes in individuals, and 23 are conserved within SARS-CoV-2, SARS-CoV, and bat coronavirus RaTG13. We find that the immunodominant epitopes of individuals with domestic (China) SARS-CoV-2 are different from those of individuals with imported (Europe) SARS-CoV-2, which may be caused by mutations on the S (G614D) and N proteins. Importantly, we find several epitopes on the S protein that elicit neutralizing antibodies against D614 and G614 SARS-CoV-2, which can contribute to vaccine design against coronaviruses. B cell epitopes of SARS-CoV-2 are obtained using structure-based approaches The predicted epitopes effectively induce robust antibody responses D614 and G614 SARS-CoV-2 display different immunodominant epitopes Epitopes on S protein elicit D614 and/or G614 SARS-CoV-2-neutralizing antibodies

Abstract
This study demonstrates the applications of Bacillus coagulans in alcohol elimination. Bacillus coagulans has recently drawn tremendous interest in the food industry and medicine considering its great environmental tolerance and beneficial effects on improving gastrointestinal diseases. However, few scientific reports connect its utilities with alcohol elimination. In this study, we introduced the unique strain B. coagulans TCI711 for such exploration. TCI711 contained alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) by mass spectrum and resisted gastric acid and bile acid. Also, taking TCI711 capsules for a week can significantly improve alcohol metabolism in humans (breath alcohol level indicated 0 mg/kg in 2 h after drinking 75 mL of whisky). In brief, this exploratory research unveiled the potent applications of B. coagulans in alcohol elimination in humans.

Abstract
Objective: To investigate the association of age-related white matter hyperintensity (WMH) with brain atrophy and cognitive impairment in patients with Parkinson's disease (PD). Methods: Consecutive samples of a prospective PD cohort with complete 3-dimensional magnetic resonance imaging in the Department of Movement Disorders in Beijing Tiantan Hospital, Capital Medical University, from October 2018 to August 2019 was retrospectively analyzed. Cognition was evaluated by Mini-Mental State Scale (MMSE) and Montreal Cognitive Assessment (MoCA). The severity of WMH was semi-quantitatively measured by Fazekas scale (0-6 points), and the mean cortical thickness and thalamus volume were calculated by FreeSurfer software. The demographic and disease characteristics, the severity of WMH, the mean cortical thickness and thalamus volume were respectively compared between PD patients with and without dementia. Moreover, univariate and multivariate generalized linear models were used to analyze the correlation of the severity of WMH with brain atrophy and MoCA. Results: A total of 225 patients with PD were included in the study, with a median age of 66 years old. Comparisons between groups suggested that patients with dementia were with severer WMH, older, and had lower levels of serum cholesterol and low-density lipoprotein and more reduced mean cortical thickness than those without dementia (all P<0.05), but no significant difference in the thalamus volume was found between the two groups. The generalized linear model showed that the cognitive impairment of PD patients was significantly correlated with WMH (β=-0.021, 95%CI:-0.040--0.002, P=0.032), but independent of age, cortical thickness, and levels of serum cholesterol and low-density lipoprotein. Conclusion: WMH may worsen PD cognitive impairment independent of brain atrophy. Clinical prevention and treatment of cerebral small vessel disease may have protective effects on cognitive function in patients with PD.

Abstract
Magnolia officinalis, as a well-known herb worldwide, has been widely used to treat multiple diseases for a long time. In this study, the petroleum ether extract from M. officinalis showed effective antifungal activity against seven plant pathogens (particularly against R. solani with an inhibition rate of 100.00% at 250 μg/mL). Honokiol and magnolol, isolated by the bioassay-guided method, exhibited greater antifungal activity than tebuconazole (EC50 = 3.07 μg/mL, p ≤ 0.001) against R. solani, which EC50 values were 2.18 μg/mL and 3.48 μg/mL, respectively. We used transcriptomics to explore the mechanism of action of honokiol against R. solani. Results indicated that honokiol may exert antifungal effects by blocking the oxidative phosphorylation metabolic pathway. Further studies indicated that honokiol induced ROS overproduction, disrupted the mitochondrial function, affected respiration, and blocked the TCA cycle, which eventually inhibited ATP production. Besides, honokiol also damaged cell membranes and caused morphological changes. This study demonstrated that the lignans isolated from M. officinalis possess the potential to be developed as botanical fungicides.

Abstract
Phytopathogenic fungal infections have become a major threat to agricultural production, food security, and human health globally, and novel antifungal agents with simple chemical scaffolds and high efficiency are needed. In this study, we designed and synthesized 38 8-hydroxyquinoline metal complexes and evaluated their antifungal activities. The results showed that most of the tested compounds possessed remarkable in vitro antifungal activity. Especially, compound 1e exhibited the highest antifungal potency among all target compounds, with EC50 values of 0.0940, 0.125, 2.95, and 5.96 μg/mL, respectively, against Sclerotinia sclerotiorum, Botrytis cinerea, Fusarium graminearum, and Magnaporthe oryzae. Preliminary mechanistic studies had shown that compound 1e might cause mycelial abnormalities of S. sclerotiorum, cell membrane permeability changes, leakage of cell contents, and inhibition of sclerotia formation and germination. Moreover, the results of in vivo antifungal activity of compound 1e against S. sclerotiorum showed that 1e possessed higher curative effects than that of the positive control azoxystrobin. Therefore, compound 1e is expected to be a novel leading structure for the development of new antifungal agents.

Abstract
Screening and therapeutic programs for colorectal cancer (CRC) are invasive or not effective and unable to meet patient needs. Major advances in immunogenomics may change this status but need more exploration. Differentially expressed genes and immune-related genes (IRGs) were identified by computational methods. A prognostic model was established and validated based on survival-related IRGs via stepwise multivariate Cox regression analysis. Nine IRGs were selected and identified as survival-related genes. A 7-gene prognostic model could offer a preliminary and valid determination of risk in CRC patients. The area under the curve of the receiver operating characteristic was 0.672. The 7-gene prognostic model might be used as a novel prognostic tool in CRC patients.

Abstract
Objectives: To evaluate the efficacy of interventional bronchoscopy for the treatment of scarring airway stenosis and to analyze the influencing factors related to the success rate. Methods: Between January 2013 to December 2016, 301 patients with scarring airway stenosis treated by interventional bronchoscopy in 18 tertiary hospitals were reviewed retrospectively. The methods of interventional bronchoscopy included electric knife cutting, laser cauterization, balloon dilation, cryotherapy, local drug usage and/or stenting. Airway stenosis characteristics and patients' performance status at baseline and after interventional bronchoscopy were recorded. The interval days between the first two interventional bronchoscopy treatment (maintained patency time) and the final treatment efficacy were recorded. Results: The clinical stability rate of interventional bronchoscopy for the treatment of scarring tracheal stenosis was 67.8% (204/301) . Stenosis sites (OR 1.548; 95% CI: 1.038-2.307, P=0.032) , dyspnea index (OR 2.140; 95% CI: 1.604-2.855, P<0.001) , and interventional method (OR 0.458; 95% CI: 0.267-0.787, P=0.005) were independent predictors associated with the efficacy of interventional bronchoscopy treatment. Stenosis sites (OR 1.508; 95% CI: 1.273-1.787, P<0.001) , stenosis grade (OR 1.581; 95% CI: 1.029-2.067, P=0.001) , anesthesia method (OR 1.581; 95% CI: 1.029-2.067, P<0.001) , and local drug usage (OR 1.304; 95% CI: 1.135-1.497, P<0.001) were independent predictors associated with the maintained patency time after first interventional bronchoscopy treatment. Conclusion: Interventional bronchoscopy is a useful treatment method for scarring airway stenosis. Enough attention should be paid to influencing factors in order to improve treatment efficacy during the treatment process.

Abstract
Objective: To understand the characteristics and differences of diarrhea-related symptoms caused by different pathogens, and the clinical features of various pathogens causing diarrhea. Methods: Etiology surveillance program was conducted among 20 provinces of China from 2010 to 2016. The acute diarrhea outpatients were collected from clinics or hospitals. A questionnaire was used to survey demographics and clinical features. VFeces samples were taken for laboratory detection of 22 common diarrhea pathogens, to detect and analyze the clinical symptom pattern characteristics of the patient's. Results: A total of 38 950 outpatients were enrolled from 20 provinces of China. The positive rates of Rotavirus and Norovirus were the highest among the five diarrhea-causing viruses (Rotavirus: 18.29%, Norovirus: 13.06%). In the isolation and culture of 17 diarrhea-causing bacterial, Escherichia coli showed the highest positive rates (6.25%). The clinical features of bacterial diarrhea and viral diarrhea were mainly reflected in the results of fecal traits and routine examination, but pathogenic Vibrio infection was similar to viral diarrhea. Conclusion: Infectious diarrhea presents different characteristics due to various symptoms which can provide a basis for clinical diagnosis.

Abstract
In patients with preserved ejection fraction or right bundle branch block (RBBB) pattern requiring a high percentage of ventricular pacing, His‐bundle pacing (HBP) might be an alternative to biventricular pacing, although the high threshold occasionally occurs. We provided a case of the intrinsic RBBB correction by capturing intra‐Hisian left bundle branch (LBB) or distal His‐bundle with different output settings. LBB pacing had the advantage of a much lower threshold while remained most synchrony as HBP. LBB pacing might be a promisingly safe and effective procedure for patients with high‐grade atrioventricular (AV) block and RBBB pattern.

Abstract
PARP10 is an intracellular mono-ADP ribosyltransferase and recent reports suggest that it regulates proliferation of some cell types. However, its effect on the proliferation of colorectal carcinoma cells has not yet been systematically reported. We explored the influence of PARP10 on the proliferation of several colorectal carcinoma cell types and carried out initial studies on the underlying mechanisms. Inhibition of the enzymatic activity of PARP10 led to significantly decreases in proliferative ability in LoVo cells and CT26 cells in vitro and suppressed growth of CT26 tumours in the subaxilliary region in Balb/c mice in vivo. Cell-cycle arrest accompanied these observations. Expression of the nuclear transfer factor β-catenin and it trans-location to the nucleus were also affected and the expression of its associated signal proteins Axin2 and c-Myb were increased and decreased, respectively. We demonstrate that PARP10 promotes proliferation of those colorectal carcinoma cells which express significant levels of PARP10. This promotion is suppressed when the enzymatic activity is inhibited. β-Catenin is likely to be the mediator of the antiproliferative effect.

Abstract
The diphenylsulfone-3,3'-disulfo-4,4'-dicarboxylic acid (H4-DPSDSDC) ligand and its coordination polymers, [K2Zn(C14H6S3O12)(H2O)4]n (1) and {[Cu3(μ3-OH)2(C14H6S3O12)(H2O)3(DMF)]·3(H2O)}n (2) (C14H6S3O12 = diphenylsulfone-3,3'-disulfo-4,4'-dicarboxylate), were synthesized. The Zn(H2O)4 units in 1 are connected by DPSDSDC4- ligands to generate a one-dimensional (1D) chain, which is bridged by K-O bonds associated with bridging water molecules and sulfonate groups to yield a two-dimensional (2D) layer. In 2, the 1D hydroxyl-bridging Cu(II) chains are connected by DPSDSDC4- ligands to give a 2D layer. The 2D layers in 1 and 2 are further connected by interlayered hydrogen bonds to give three-dimensional (3D) frameworks. Compounds 1 and 2 have good conductivities of 1.57 × 10-4 and 5.32 × 10-5 S cm-1, respectively. Continuous well-defined hydrogen bonding networks associated with water molecules, sulfonate groups, and carboxylate groups were observed in compounds 1 and 2. Such hydrogen bonding networks provide hydrophilic domains and effective transfer pathways for protons. Here, we present elegant examples of a precise determination of the pathways for proton transport.

Abstract
Objective: To examine the value serum calcium and intact parathyroid hormone (iPTH) levels measured on the first day after total thyroidectomy on prediction for permanent hypoparathyroidism. Methods: Totally 546 patients with thyroid cancer and benign thyroid lesions who underwent total thyroidectomy at Department of General Surgery, Beijing Chaoyang Hospital, Capital Medical University from February 2008 to December 2018 were analyzed retrospectively. There were 158 males and 388 females aging (50.9±13.2) years (range: 19.0 to 79.2 years). Serum calcium and iPTH levels were collected before surgery, on the first day and 6 months after surgery. Logistic regression was used to analyze the correlation between each data and the occurrence of permanent hypoparathyroidism after surgery.The area under the receiver operating characteristic curve was used to evaluate the predictive power of iPTH for postoperative occurrence of permanent hypoparathyroidism. Results: Among the 546 cases of total thyroidectomy, 22 cases of permanent hypoparathyroidism occurred, with an incidence of 4.0% (22/546). Multivariate analysis showed that iPTH levels on the first day after total thyroidectomy (OR=2.932, 95%CI: 1.129 to 7.616, P=0.027) and serum calcium levels (OR=2.584, 95%CI: 1.017 to 6.567, P=0.046) were independent prognosis factors for postoperative permanent hypoparathyroidism. When the threshold value of iPTH at 24 hours after total thyroidectomy was 5.51 ng/L, the AUC was 0.956 (95%CI: 0.936 to 0.972, P=0.000), sensitivity was 100%, specificity was 85.1%, positive predictive value was 22%, negative predictive value was 100%. When the threshold value of serum calcium at 24 hours after total thyroidectomy was 1.93 mmol/L, the AUC was 0.733 (95%CI: 0.694 to 0.770, P=0.000), sensitivity was 63.6%, specificity was 78.1%, positive predictive value of 10.8% and negative predictive value of 98.1%. Conclusions: Serum iPTH and calcium levels on the first day after total thyroidectomy were related to the occurrence of permanent hypoparathyroidism postoperatively. The predictive value of iPTH level is higher than that of serum calcium level.

Abstract
Currently, valuable tickets are scanned and verified by embedding quick response (QR) codes, but few studies have embedded encrypted information into QR codes to prevent counterfeiting. In the existing literature on color image-based QR codes, there is room for improvement in image quality and anti-counterfeiting functions. We propose an optically decrypted microstructure overlapping image technology, hiding the information points of two-dimensional barcodes on the image reservation area in the ticket, and using the optical principle to use the lenticular lens as a decryption component, to make the image produce continuous dynamic effects and increase the difficulty of forgery. In addition, the distribution of embedded parameters and differences will also affect the distortion of hidden information, which may cause the QR code to fail to read, so the median edge detection predictor is proposed for distortion control comparison. The experimental results prove that our method provides low distortion of information-hiding technology.

Abstract
Bombyx mori nucleopolyhedrovirus (BmNPV) is a major pathogen causing severe economic loss. However, the molecular mechanism of silkworm resistance to BmNPV and the interactions of this virus with the host during infection remain largely unclear. To explore the virus-binding proteins of silkworms, the midgut subcellular component proteins that may interact with BmNPV were analyzed in vitro based on one- and two-dimensional electrophoresis and far-western blotting combined with mass spectrometry (MS). A total of 24 proteins were determined to be specifically bound to budded viruses (BVs) in two subcellular fractions (mitochondria and microsomes). These proteins were involved in viral transportation, energy metabolism, apoptosis and viral propagation, and they responded to BmNPV infection with different expression profiles in different resistant strains. In particular, almost all the identified proteins were downregulated in the A35 strain following BmNPV infection. Interestingly, there were no virus-binding proteins identified in the cytosolic fraction of the silkworm midgut. Two candidate proteins, RACK1 and VDAC2, interacted with BVs, as determined with far-western blotting and reverse far-western blotting. We speculated that the proteins interacting with the virus could either enhance or inhibit the infection of the virus. The data provide comprehensive useful information for further research on the interaction of the host with BmNPV.

Abstract
Objective: To investigate the high resolution CT (HRCT) features of lung adenocarcinoma for differentiating synchronous multiple lung adenocarcinoma from lung adenocarcinoma with intrapulmonary metastasis. Methods: The clinical and imaging features of 131 lesions from 62 patients of synchronous multiple primary lung adenocarcinoma (primary group) and 67 lesions from 31 patients of lung adenocarcinoma with intrapulmonary metastases (metastasis group) were retrospectively analyzed. According to the types of lesion, including pure ground glass nodule (pGGN), mixed ground glass nodule (mGGN) and solid nodule (SN), the image feature matching types of patients were divided into 7 types. The differences of image feature matching types between the primary group and the metastasis group were compared. Multiple lesions in the lung of patients were classified into the main lesion and the concomitant lesions according to their size. The differences including the size of the main lesion and the concomitant lesion (long diameter of nodule, long diameter of solid component in nodule), whether it contains ground glass components in nodule, shape, lobulation, margin, spiculation, bubble-like lucency, pleural retraction and pleural attachment were recorded and analyzed. The differences of image features of main lesion and the concomitant lesion in the primary group and the metastasis group were compared. Results: The image feature matching types of pGGN + mGGN and mGGN + mGGN were more common in the primary group, and the ground glass component contained pGGN or mGGN was accounted for 62.9%(39/62). At least one lesion containing the ground glass component was accounted for 96.8% (60/62). There were two types in metastatic groups, mGGN+ SN and SN+ SN accounting for 6.5% (2/31) and 93.5% (29/31), respectively. There were significant differences in image feature matching types between the primary group and metastatic group (P<0.01). Univariate analysis of the main lesions between the two groups showed that the gender, smoking history, long diameter of the main lesion, long diameter of the solid component, the ground glass component and pleural attachment were statistically different (P<0.05). Further analysis by multivariate logistic regression showed that the male (OR=5.742, P=0.010), SN (OR=41.291, P<0.01) and pleural attachment (OR=9.288, P=0.001) were the three significant risk factors associated with the main lesions in metastasis group.The most common concomitant lesions in primary group were pGGN, containing the ground glass component. However, all of the concomitant lesions in the metastatic group were SN (P<0.01), showing round lesions with well-defined margin, attaching the pleura (P<0.05). Conclusions: The HRCT features of lung adenocarcinoma can differentiate synchronous multiple lung adenocarcinoma from lung adenocarcinoma with intrapulmonary metastasis. At least one lesion contains ground glass components (pGGN or mGGN) in synchronous multiple primary lung adenocarcinoma, while SN is more common in lung adenocarcinoma with lung metastasis. Lung cancer with intrapulmonary metastasis can be considered when the main lesion is SN with pleural attachment and the intrapulmonary accompanying lesion is also solid nodules without lobular, speculation and bubble-like lucency.

Abstract
BACKGROUND Major depressive disorder (MDD) is a highly prevalent psychiatric disorder, and inflammation has been considered crucial components of the pathogenesis of depression. NLRP1 inflammasome-driven inflammatory response is believed to participate in many neurological disorders. However, it is unclear whether NLRP1 inflammasome is implicated in the development of depression. METHODS Animal models of depression were established by four different chronic stress stimuli including chronic unpredictable mild stress (CUMS), chronic restrain stress (CRS), chronic social defeat stress (CSDS), and repeat social defeat stress (RSDS). Depressive-like behaviors were determined by sucrose preference test (SPT), forced swim test (FST), tail-suspension test (TST), open-field test (OFT), social interaction test (SIT), and light-dark test (LDT). The expression of NLRP1 inflammasome complexes, BDNF, and CXCL1/CXCR2 were tested by western blot and quantitative real-time PCR. The levels of inflammatory cytokines were tested by enzyme-linked immunosorbent assay (ELISA) kits. Nlrp1a knockdown was performed by an adeno-associated virus (AAV) vector containing Nlrp1a-shRNA-eGFP infusion. RESULTS Chronic stress stimuli activated hippocampal NLRP1 inflammasome and promoted the release of pro-inflammatory cytokines IL-1β, IL-18, IL-6, and TNF-α in mice. Hippocampal Nlrp1a knockdown prevented NLRP1 inflammasome-driven inflammatory response and ameliorated stress-induced depressive-like behaviors. Also, chronic stress stimuli caused the increase in hippocampal CXCL1/CXCR2 expression and low BDNF levels in mice. Interestingly, Nlrp1a knockdown inhibited the up-regulation of CXCL1/CXCR2 expression and restored BDNF levels in the hippocampus. CONCLUSIONS NLRP1 inflammasome-driven inflammatory response contributes to chronic stress induced depressive-like behaviors and the mechanism may be related to CXCL1/CXCR2/BDNF signaling pathway. Thus, NLRP1 inflammasome could become a potential antidepressant target.

Abstract
PURPOSE Beta-lactams (BL), the most commonly prescribed class of antibiotics, are recommended as the first-line therapy for multiple indications in infectious disease guidelines. Meropenem (MERO) is frequently used in intensive care units (ICU) to treat bacterial infections with or without sepsis. The pharmacokinetics of MERO display a large variability in patients admitted to ICUs due to altered pathophysiology. The aim of this study was to perform an external evaluation of published population pharmacokinetic models of MERO in order to test their predictive performance in a cohort of ICU adult patients. METHODS A literature search in PubMed/Medline database was made following the PRISMA statement. External evaluation was performed using NONMEM software, and the bias and inaccuracy values were calculated. RESULTS An external validation dataset from the Timone Hospital in Marseille, France, included 84 concentration samples from 27 patients. Four models of MERO were identified according to the inclusion criteria of the study. None of the models presented acceptable values of bias and inaccuracy. CONCLUSION While performing external evaluations on some populations may confirm a model's suitability to diverse groups of patients, there is still some variability that cannot be explained nor solved by the procedure. This brings to light the difficulty to develop only one model for ICU patients and the need to develop one specific model to each population of critically ill patients.

INTRODUCTION Gastric cancer is the fourth most common cancer in the world. By the time the patients are diagnosed with stage IV gastric cancer, many patients already have distant metastases. There is no unified systemic treatment plan in existence. The use of gastrectomy is ambiguous in patients with stage IV gastric cancer. The objective of this study was to evaluate the beneficial outcome of gastrectomy in patients with stage IV gastric cancer. METHODS Clinical information of patients with gastric cancer from 2000 to 2010 in the Surveillance, Epidemiology, and End Results database were extracted and analysed. The risk factors for stage IV gastric cancer were also analysed. RESULTS We observed that the median survival time for patients after surgery was greater than that for patients not treated surgically. The five-year survival rate for chemotherapy patients was higher than that of non-chemotherapeutic patients. Patients who receive both chemotherapy and surgery could achieve a more significant survival benefit. The risks following gastrectomy (partial, subtotal, hemi-) were lower than those of other surgical procedures, which provided guidance on the choice of surgical method. The numbers of regional lymph node metastasis were found to be related to prognosis. CONCLUSIONS In patients with stage IV gastric cancer, gastrectomy (partial, subtotal or hemi) should be selected when surgery is necessary. The number of regional lymph node metastasis could be considered as a prognostic factor for patients with stage IV gastric cancer and lymph node dissection could reduce the risk of patients undergoing surgery.

Abstract
Objective: To systematically understand the global research progress in the construction and validation of lung cancer risk prediction models. Methods: "lung neoplasms" , "lung cancer" , "lung carcinoma" , "lung tumor" , "risk" , "malignancy" , "carcinogenesis" , "prediction" , "assessment" , "model" , "tool" , "score" , "paradigm" , and "algorithm" were used as search keywords. Original articles were systematically searched from Chinese databases (CNKI, and Wanfang) and English databases (PubMed, Embase, Cochrane, and Web of Science) published prior to December 2018. The language of studies was restricted to Chinese and English. The inclusion criteria were human oriented studies with complete information for model development, validation and evaluation. The exclusion criteria were informal publications such as conference abstracts, Chinese dissertation papers, and research materials such as reviews, letters, and news reports. A total of 33 papers involving 27 models were included. The population characteristics of all included studies, study design, predicting factors and the performance of models were analyzed and compared. Results: Among 27 models, the number of American-based, European-based and Asian-based model studies was 12, 6 and 9, respectively. In addition, there were 6 Chinese-based model studies. According to the factors fitted into the models, these studies could be divided into traditional epidemiological models (11 studies), clinical index models (6 studies), and genetic index models (10 studies). 15 models were not validated after construction or were cross-validated only in the internal population, and the extrapolation effect of models was not effectively evaluated; 8 models were validated in single external population; only 4 models were verified in multiple external populations (3-7); the area under the curve (AUC) of models ranged from 0.57 to 0.90. Conclusion: Research on risk prediction models for lung cancer is in development stage. In addition to the lack of external validation of existing models, the exploration of potential clinical indicators was also limited.

Abstract
Previous studies have revealed that some proteins in Bombyx mori larvae digestive juice show antiviral activity. Here, based on the label-free proteomics data, BmLipase member H-A (BmLHA) was identified as being involved in the response to BmNPV infection in B. mori larvae digestive juice. In the present study, a gene encoding the BmLHA protein in B. mori was characterized. The protein has an open reading fragment of 999 bp, encoding a predicted 332 amino acid residue-protein with a molecular weight of approximately 35.9 kDa. The phylogenetic analysis revealed that BmLHA shares a close genetic distance with Papilio xuthus Lipase member H-A. BmLHA was highly expressed in the middle part of the B. mori gut, and the expression level increased with instar rising in larvae. There was higher expression of BmLHA in A35 than in P50 strains, and it was upregulated in both A35 and P50 strains, following BmNPV infection. The expression level of VP39 decreased significantly in appropriate recombinant-BmLHA-treated groups compared with the PBS-treated group in B. mori larvae and BmN cells. Meanwhile, overexpression of BmLHA significantly reduced the infectivity of BmNPV in BmN cells. These results indicated that BmLHA did not have digestive function but had anti-BmNPV activity. Taken together, our work provides valuable data for the clarification of the molecular characterization BmLHA and supplements research on proteins of anti-BmNPV activity in B. mori.

Abstract
BACKGROUND P53 is the most frequently mutated gene in most tumour types, and the mutant p53 protein accumulates at high levels in tumours to promote tumour development and progression. Thus, targeting mutant p53 for degradation is one of the therapeutic strategies used to manage tumours that depend on mutant p53 for survival. Buxus alkaloids are traditionally used in the treatment of cardiovascular diseases. We found that triterpenoid alkaloids extracted from Buxus sinica found in the Yunnan Province exhibit anticancer activity by depleting mutant p53 levels in colon cancer cells. PURPOSE To explore the anticancer mechanism of action of the triterpenoid alkaloid KBA01 compound by targeting mutant p53 degradation. STUDY DESIGN AND METHODS Different mutant p53 cell lines were used to evaluate the anticancer activity of KBA01. MTT assay, colony formation assay and cell cycle analysis were performed to examine the effect of KBA01 on cancer cell proliferation. Western blotting and qPCR were used to investigate effects of depleting mutant p53, and a ubiquitination assay was used to determine mutant p53 ubiquitin levels after cells were treated with the compound. Co-IP and small interfering RNA assays were used to explore the effects of KBA01 on the interaction of Hsp90 with mutant p53. RESULTS The triterpenoid alkaloid KBA01 can induce G2/M cell cycle arrest and the apoptosis of HT29 colon cancer cells. KBA01 decreases the stability of DNA contact mutant p53 proteins through the proteasomal pathway with minimal effects on p53 mutant protein conformation. Moreover, KBA01 enhances the interaction of mutant p53 with Hsp70, CHIP and MDM2, and knocking down CHIP and MDM2 stabilizes mutant p53 levels in KBA01-treated cells. In addition, KBA01 disrupts the HSF1-mutant p53-Hsp90 complex and releases mutant p53 to enable its MDM2- and CHIP-mediated degradation. CONCLUSION Our study reveals that KBA01 depletes mutant p53 protein in a chaperone-assisted ubiquitin/proteasome degradation pathway in cancer cells, providing insights into potential strategies to target mutant p53 tumours.

Abstract
OBJECTIVE The purpose of this study was to evaluate the effect of a web-based survivorship care plan (SCP) computerized application (APP): (SCP-A) on women's unmet needs, fear of recurrence, symptom distress, anxiety, depression, and quality of life (QoL). METHODS Women diagnosed with breast cancer, who had completed their primary treatment but less than 5 years without a sign of recurrence (N = 165) were randomized to a SCP-A or a control group. Self-reported questionnaires were completed by the both groups at baseline (T0), 5 weeks (T1), 3 months (T2), 6 months (T3), and 12 months (T4). RESULTS Controlling for relevant covariates, mixed effect model analyses revealed a significant decrease in women in the SCP-A group compared to the control group for total unmet needs since T3 (p < .004) and fear of recurrence since T4 (p = .02). Women in the SCP-A group also reported significant improvements in QoL at T4 (p < .001) relative to those in the control group. CONCLUSION Providing SCP using an information website application for women with breast cancer can decrease unmet needs, fear of recurrence, and improve quality of life during short-term and long-term use. PRACTICE IMPLICATIONS Web-based information that provides survivorship care plans for breast cancer survivors are beneficial.

Abstract
AIM To study the effects of TGF-β1 on the plasminogen activation (PA) system of stem cells from the apical papilla (SCAP) and its signalling. METHODOLOGY SCAP cells were isolated from the apical papilla of immature permanent teeth extracted for orthodontic reasons. They were exposed to various concentration of TGF-β1 with/without pretreatment and coincubation by SB431542 (ALK/Smad2/3 inhibitor), or U0126 (MEK/ERK inhibitor). MTT assay, Western blotting and enzyme-linked immunosorbent assay (ELISA) were used to detect their effects on cell viability, and the protein expression of plasminogen activator inhibitor-1 (PAI-1), urokinase-type plasminogen activator (uPA), uPA receptor (uPAR) and their secretion. The paired Student's t-test was used for statistical analysis. RESULTS TGF-β1 significantly stimulated PAI-1 and soluble uPAR (suPAR) secretion of SCAP cells (P < 0.05), whereas uPA secretion was inhibited. Accordingly, TGF-β1 induced both PAI-1 and uPAR protein expression of SCAP cells. SB431542 (an ALK5/Smad2/3 inhibitor) pretreatment and coincubation prevented the TGF-β1-induced PAI-1 and uPAR of SCAP. U0126 attenuated the TGF-β1-induced expression/secretion of uPAR, but not PAI-1 in SCAP. SB431542 reversed the TGF-β1-induced decline of uPA. CONCLUSIONS TGF-β1 may affect the repair/regeneration activities of SCAP via differential increase or decrease of PAI-1, uPA and uPAR. These effects induced by TGF-β1 are associated with ALK5/Smad2/3 and MEK/ERK activation. Elucidation the signalling pathways and effects of TGF-β1 is useful for treatment of immature teeth with open apex by revascularization/revitalization procedures and tissue repair/regeneration.

Abstract
PURPOSE Antimalarial drug resistance is one of the major challenges in global efforts to control and eliminate malaria. In 2006, sulfadoxine-pyrimethamine (SP) replaced with artemisinin-based combination therapy (ACT) on Bioko Island, Equatorial Guinea, in response to increasing SP resistance, which is associated with mutations in the dihydrofolate reductase (Pfdhfr) and dihydropteroate synthase (Pfdhps) genes. PATIENTS AND METHODS To evaluate the trend of molecular markers associated with SP resistance on Bioko Island from 2011 to 2017, 179 samples collected during active case detection were analysed by PCR and DNA sequencing. RESULTS Pfdhfr and Pfdhps gene sequences were obtained for 90.5% (162/179) and 77.1% (138/179) of the samples, respectively. For Pfdhfr, 97.5% (158/162), 95.7% (155/162) and 98.1% (159/162) of the samples contained N51I, C59R and S108N mutant alleles, respectively. And Pfdhps S436A, A437G, K540E, A581G, and A613S mutations were observed in 25.4% (35/138), 88.4% (122/138), 5.1% (7/138), 1.4% (2/138), and 7.2% (10/138) of the samples, respectively. Two classes of previously described Pfdhfr-Pfdhps haplotypes associated with SP resistance and their frequencies were identified: partial (IRNI-SGKAA, 59.4%) and full (IRNI-SGEAA, 5.5%) resistance. Although no significant difference was observed in different time periods (p>0.05), our study confirmed a slowly increasing trend of the frequencies of these SP-resistance markers in Bioko parasites over the 7 years investigated. CONCLUSION The findings reveal the general existence of SP-resistance markers on Bioko Island even after the replacement of SP as a first-line treatment for uncomplicated malaria. Continuous molecular monitoring and additional control efforts in the region are urgently needed.

Abstract
Objective: To compare the efficacy and safety of two procedures in the treatment of hemorrhoid: the procedure for prolapse and hemorrhoids (PPH) and stapled transanal rectal resection (STARR). Methods: A retrospective cohort research was conducted. Clinical data of 263 patients undergoing the first elective surgery for grade IV hemorrhoids by the same team of surgeons at our department from January 2015 to December 2016 were analyzed retrospectively, while those had other anorectal diseases, emergency surgery, inflammatory bowel disease, tumor and incomplete clinical data were excluded. PPH was performed in 129 patients and STARR was performed in 134 patients. PPH procedure: a circular purse 2-0 string suture was made at 4 cm above the dentate line; in accordance with the standard protocol, the PPH circular stapling devicewas introduced; the suture was closed, and a pull-through followed; the traction was continued; the stapler was fired; the prolapsed mucosa and submucosa were removed. STARR procedure: 3-5 needles were sutured in the anterior rectal mucosa, protecting the posterior wall mucosa; with the help of a finger the PPH stapler was inserted into the vaginal lumen; the sutures were hooked from both sides of the stapler to maintain traction; according to the disease condition, the suturewas tightened appropriately; stapler was screwed and activated; the anterior wall mucosa was removed; the joint of the both ends of anastomosis was cut; the posterior wall mucosa was removed as well. The short-term efficacy, surgical safety and prognosis of the two groups were compared. Results: There were 67 males (51.9%) in the PPH group and 57 (42.5%) males in the STARR group. The median age of the two groups was 51.0 (22.0, 80.0) years and 49.0 (24.0, 74.0) years, respectively. There were no significant differences in the baseline data between the two groups (all P>0.05). No significant differences in the intraoperative bleeding, length of hospital stay, postoperative analgesic drug use, postoperative bleeding, postoperative infection, etc. were found between two groups (all P>0.05). As compared to PPH group, STAAR group had longer operation time and higher hospitalization cost with significant differences [(44.0±19.3) minutes vs. (26.3±8.5) minutes, t=9.701, P=0.001; (11 047±473) yuan vs. (7674±309) yuan, t=32.826, P=0.001]. One case in STAAR group developed rectovaginal fistula. The median follow-up period of the whole group was 40 (33, 52) months. A total of 108 cases in STARR group and 114 cases in PPH group completed the follow-up. The 3-year disease-relapse rate was 0 in STARR group and 4.2% in PPH group (P=0.042). Conclusion: STARR procedure can improve the prognosis in the treatment of grade IV hemorrhoid, but attention should be paid to the development of complications.

Abstract
As a member of photosynthetic bacteria, Rhodopseudomonas palustris, which has extraordinary metabolic versatility, has been applied as one of potential probiotics in feed industry. To explore whether R. palustris can increase rumen microbial viability and thus improve microbial fermentation, a 2×5 factorial experiment was conducted to evaluate the effect of R. palustris at dose rates of 0, 1.3, 2.6, 3.9, 5.2×106 cfu/ml on ruminal fermentation of two representative total mixed rations (HY, a ration for high-yield (>32 kg/d) lactating cows; LY, a ration for low-yield (<25 kg/d) lactating cows). After a 48 h in vitro rumen incubation, both rations resulted in different fermentation characteristics. The HY in comparison with LY group presented greater in vitro dry matter disappearance (IVDMD), cumulative gas production (GP48) and total volatile fatty acids (VFA, P<0.01). Increasing R. palustris addition linearly increased IVDMD (P<0.01) and GP48 (P<0.05), and the IVDMD increment in response to R. palustris addition was greater in LY than HY group (6.4% vs 1.4%). Meanwhile, increasing R. palustris addition also linearly enhanced microbial protein synthesis and increased total VFA production (P<0.01), especially in LY group (up to 21.5% and 24.5% respectively). Unchanged acetate and declined propionate in molar percentage were observed in response to the R. palustris addition. Furthermore, increasing R. palustris addition altered fermentation gas composition in which molar O2 proportion in headspace of fermentation system was linearly reduced by 46.1% in LY and 32.9% in HY group, respectively (P<0.01), and methane production in both ration groups was enhanced by 1.9-4.1% (P=0.02). In summary, the R. palustris addition exhibited high potential for promoting the growth of rumen microorganism and enhancing microbial fermentation towards non-glucogenic energy supply by maintaining an anaerobic environment to microbe equilibrium.

Abstract
Background Evidences regarding the associations between maternal upper respiratory tract infection/influenza during pregnancy and the risk of congenital heart disease (CHD) is still controversial. This study was specifically designed to examine the associations by a case-control study and a meta-analysis of the published evidences and our finding. Methods A hospital-based case-control study involving 262 children with simple CHD and 262 children with complex CHD, along with 262 control children, was conducted through June, 2016 to December, 2017. All children were aged 0–2 years old. Furthermore, a meta-analysis based on both previously published studies and our case-control study was performed. Results In the case-control study, after adjusting for possible confounders, maternal upper respiratory tract infection/influenza during early pregnancy was found to be related to an increased risk of CHD (OR = 3.40 and 95% CI: 2.05–5.62 for simple CHD; OR = 2.39 and 95% CI: 1.47–3.88 for complex CHD). After a meta-analysis, the adverse impact was still kept significant (OR = 1.47 and 95% CI: 1.28–1.67 for simple CHD; OR = 1.44 and 95% CI: 1.14–1.75 for complex CHD). The very similar associations were also observed among single type of CHD, herein, ventricular septal defects (VSD) and tetralogy of fallot (TOF) in the case-control study. In the subsequent meta-analysis, however, the significant association only existed in VSD. Conclusions Although there is still conflicting in TOF, the results are overall consistent, which provide new enforced evidence that maternal upper respiratory tract infection/influenza during early pregnancy, in general, play an important role in the occurrence of CHD.

Abstract
Iodine nutrition surveillance of vulnerable population was conducted in 18 cities of Henan Province in 2015. The medians and quartiles of urinary iodine concentration in women of reproductive-age (n=3 318), pregnant women (n=36 366), lactating women (n=4 153), infants <2 years of age (n=1 017), and children aged 8-10 years (n=4 806) were 202.1(124.0, 310.0), 192.4(133.6, 262.4), 168.3(119.1, 248.3), 214.2(156.1, 272.3) and 90.0 (121.8, 285.6) μg/L, respectively. Iodine status of the vulnerable populations was generally regarded as adequate in Henan Province. But the median of urinary iodine concentration of reproductive-age women were slightly above the adequate level. The proportions above iodine adequate level were 26.7% in reproductive-age women, 29.4% in pregnant women and 22.5% in children aged 8-10 years.

Abstract
The effects of biological soil crusts (BSC) on vascular plant growth can be positive, neutral or negative, and little information is available on the impacts of different BSC successional stages on vascular plant population dynamics. We analysed seedling emergence, survival, plant growth and reproduction in response to different BSC successional stages (i.e. habitats: bare soil, cyanobacteria, lichen and moss crusts) in natural populations of Echinops gmelinii Turcz. in the Tengger Desert of northwest China. The winter annual E. gmelinii is a dominant pioneer herb after sand stabilisation. During the early stages of BSC succession, the studied populations of E. gmelinii were characterised by high density, plant growth and fecundity. As the BSC succession proceeded beyond moss crusts, the fecundity decreased sharply, which limited seedling recruitment. Differences in seedling survival among the successional stages were not evident, indicating that BSC have little effect on survival in arid desert regions. Moreover, E. gmelinii biomass allocation exhibited low plasticity, and only reproductive allocation was sensitive to the various habitats. Our results further suggest that the negative effects of BSC succession on population dynamics are primarily driven by increasing topsoil water-holding capacity and decreasing rain water infiltration into deeper soil. We conclude that BSC succession drives population dynamics of E. gmelinii, primarily via its effect on soil moisture. The primary cause for E. gmelinii population decline during the moss-dominated stage of BSC succession is decreased fecundity of individual plants, with declining seed mass possibly reducing the success of seedling establishment.

Abstract
Inspired by quinine and its analogues, we designed, synthesized, and evaluated two series of quinoline small molecular compounds (a and 2a) and six series of quinoline derivatives (3a-f) for their antifungal activities. The results showed that compounds 3e and 3f series exhibited significant fungicidal activities. Significantly, compounds 3f-4 (EC50 = 0.41 μg/mL) and 3f-28 (EC50 = 0.55 μg/mL) displayed the superior in vitro fungicidal activity and the potent in vivo curative effect against Sclerotinia sclerotiorum. Preliminary mechanism studies showed that compounds 3f-4 and 3f-28 could cause changes in the cell membrane permeability, accumulation of reactive oxygen species, loss of mitochondrial membrane potential, and effective inhibition of germination and formation of S. sclerotiorum sclerotia. These results indicate that compounds 3f-4 and 3f-28 are novel potential fungicidal candidates against S. sclerotiorum derived from natural products.

Abstract
BACKGROUND Plasmodium falciparum apical membrane antigen-1 (PfAMA-1) is a promising candidate antigen for a blood-stage malaria vaccine. However, antigenic variation and diversity of PfAMA-1 are still major problems to design a universal malaria vaccine based on this antigen, especially against domain I (DI). Detail understanding of the PfAMA-1 gene polymorphism can provide useful information on this potential vaccine component. Here, general characteristics of genetic structure and the effect of natural selection of DIs among Bioko P. falciparum isolates were analysed. METHODS 214 blood samples were collected from Bioko Island patients with P. falciparum malaria between 2011 and 2017. A fragment spanning DI of PfAMA-1 was amplified by nested polymerase chain reaction and sequenced. Polymorphic characteristics and the effect of natural selection were analysed using MEGA 5.0, DnaSP 6.0 and Popart programs. Genetic diversity in 576 global PfAMA-1 DIs were also analysed. Protein function prediction of new amino acid mutation sites was performed using PolyPhen-2 program. RESULTS 131 different haplotypes of PfAMA-1 were identified in 214 Bioko Island P. falciparum isolates. Most amino acid changes identified on Bioko Island were found in C1L. 32 amino acid changes identified in PfAMA-1 sequences from Bioko Island were found in predicted RBC-binding sites, B cell epitopes or IUR regions. Overall patterns of amino acid changes of Bioko PfAMA-1 DIs were similar to those in global PfAMA-1 isolates. Differential amino acid substitution frequencies were observed for samples from different geographical regions. Eight new amino acid changes of Bioko island isolates were also identified and their three-dimensional protein structural consequences were predicted. Evidence for natural selection and recombination event were observed in global isolates. CONCLUSIONS Patterns of nucleotide diversity and amino acid polymorphisms of Bioko Island isolates were similar to those of global PfAMA-1 DIs. Balancing natural selection across DIs might play a major role in generating genetic diversity in global isolates. Most amino acid changes in DIs occurred in predicted B-cell epitopes. Novel sites mapped on a three dimensional structure of PfAMA-1 showed that these regions were located at the corner. These results may provide significant value in the design of a malaria vaccine based on this antigen.

Abstract
Objective: To evaluate the clinical application of Chinese version of Cornell assessment of pediatric delirium (CAPD) scale in children by a pilot study. Methods: A prospective observational study. From June 2017 to December 2017, the original CAPD screen was translated into Chinese and debugged cross-culturally according to the guidelines, which was further applied in the Department of Critical Care Medicine, Children's Hospital of Chongqing Medical University. The clinical data of 250 patients who were evaluated with the Chinese version of CAPD scale and Richmond agitation-sedation scale were extracted and analyzed with chi-square test or Mann-Whitney U test. Cronbach's α coefficient,Split-half coefficient and intra-group correlation coefficient were used to evaluate the reliability, while exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to evaluate the structural validity of the scale. The result was compared with the gold standard diagnostic results to evaluate the diagnostic efficacy of the CAPD. Results: Sixty-one (24.4%) patients had delirium during pediatric intensive care unit hospitalization,and significant differences existed between them and 189 patients without delirium in age (χ(2)=11.220, P=0.011), rates of mechanical ventilation (χ(2)=6.691, P=0.010) and length of PICU hospitalization (Z=10.656, P=0.001). The Chinese version of the CAPD scale had high discrimination among the 8 items in the main table without skewed distribution and discrete items. The internal and external reliability of the scale were preferable as the Cronbach's α coefficient was 0.819 and ICC value was 0.835. The KMO value of EFA was 0.834 and Bartlett spherical test showed statistical significance (χ(2)=661.440, P<0.01). CFA constructed a two-factor structural equation model with favorable fit index:Chi-square/degree of freedom (DF) ratio was 1.786 (χ(2)=33.930, P=0.019), goodness of fit index (GFI) was 0.967,adjusted GFI was 0.938,root mean square of the approximate error (RMSEA) was 0.056. A good diagnostic efficacy of this scale was demonstrated by receiver operating characteristic curve analysis as when the cut-off was 10, the area under curve was 0.99 (95%CI: 0.97-0.99), sensitivity was 96.7% (95%CI: 88.7-99.6), specificity was 93.1% (95%CI: 88.5-96.3), positive likelihood ratio was 14.0 (95%CI: 13.2-14.9), and the negative likelihood ratio was 0.035 (95%CI: 0.008-0.200). Conclusion: The Chinese version of the CAPD Scale has favorable reliability,validity,diagnostic efficacy, as well as feasibility, which should be applied in evaluation of pediatric delirium in clinical observation and research in the future.

Abstract
BACKGROUND High hepatitis B virus (HBV) DNA level is strongly associated with hepatocellular carcinoma (HCC) development in chronic HBV infection. The aim of this study was to investigate the association between intrahepatic HBV DNA titer and post-liver transplantation (LT) prognosis for HBV-related HCC (HBV-HCC) patients. METHODS A total of 60 patients with HBV-HCC who underwent LT were retrospectively studied. Using quantitative TaqMan fluorescent real-time polymerase chain reaction assay, HBV total DNA (tDNA) and covalently closed circular DNA (cccDNA) were both quantified in tumor tissue (TT) and adjacent non-tumor tissue (ANTT) from the explanted liver. RESULTS The loads of tDNA and cccDNA in ANTT were associated with serum HBV DNA levels. Multivariate analysis showed that the presence of vascular invasion and cccDNA in TT were independent risk factors for tumor recurrence. The group of patients with cccDNA titers ≥31ogl0 copies/μg in TT had significantly higher cumulative recurrence rates than those with <31ogl0 copies/μg group. The cccDNA titers predicted the tumor recurrence with an area under the receiver operating characteristic curve of 0.664. CONCLUSIONS Our findings would assist the clinical implementation of a more personalized therapy for tumor recurrence control and improve the prognosis of HBV-HCC patients.

Abstract
Multi-drug resistance (MDR) of tumor cells attenuates the efficacy of anticancer drugs and has become the main reason for chemotherapy failure. It is indispensable to establish an effective way to reverse multi-drug resistance. Our previous work has shown that down-regulation of the ERK/MAPK signaling pathway activity can reverse the drug-resistance of resistant cells. Further-more, the effect of signal transduction is strongly associated with lipid rafts. The drug-resistance is reversed successfully after lipid rafts are destroyed by heptakis(2, 6-di-O-methyl)-β-cyclodextrin (MβCD). However, the reversal of the drug-resistance is not associated with down-regulation of the expression of ERK1/2. Cell membrane permeability may increase when lipid rafts are destroyed by MβCD, causing the reversal of drug-resistance due to an increase in accumulation of the drugs in the cytoplasm. To minimize the influence of MβCD on the cell membrane structure, we selected flotillin, a marker protein of lipid rafts, as the target molecule, to further investigate the mechanism of changes in drug resistance after destruction of the lipid rafts. The effect of flotillin on the reversal of the drug resistance was examined using an RNA interference (RNAi) in a retrovirus system in human drug-resistant strains of colorectal cancer cell line HCT-15. The results demonstrate that flotillin-1 downregulation by RNAi (Flot1-RNAi) reduced the drug resistance, caused cell cycle arrest and decreased the expression of ERK1/2; however, apoptosis was not significantly affected. Knockdown of flotillin-2 by RNAi (Flot2-RNAi) had effects similar to those of Flot1-RNAi except that the effects on expression of ERK1/2 and apoptosis were different. Screening of multiple pathways indicated that the PI3K/Akt signaling pathway was closely related. This experiment demonstrates the association between PI3K and drug resistance through the activation of PI3K and suggests that PI3K may play a key role during the development of resistance in CRC. The results reveal that the levels of IRS-1 and PI3K proteins in the Flot1-RNAi and Flot2-RNAi groups were significantly down-regulated. Knockdown of flotillins by RNAi reduced the resistance of HCT-15/ADM cells; the results investigations of the Akt pathway indicate a decrease in resistance after lipid raft destruction. These data confirm that knockdown of flotillin reduces the resistance of HCT-15/ADM cells, and the mechanism may be relevant to the PI3K/Akt pathway. Additionally, flotillin may be used as a potential target for chemotherapy in the treatment of colorectal cancer.

Abstract
Astrocytes are major glial cells critically in maintaining stability of the central nervous system and functional activation of astrocytes occurs rapidly in various diseased or traumatic events. We are interested in functional changes of astrocytes during the spinal cord injury, and studied expression of nerve growth factor (NGF) in activated astrocytes by mouse model of contused spinal cord injury and cell culture experiment. It revealed that the spinal cord injury resulted in apparent activation of astrocytes and microglial cells and decreased BMS scores. A larger number of astrocytes showed immunoreactivity to proNGF in the injured spinal cord areas, and proNGF expression increased and remained high level at 7 to 14dpi, which was coincided with upregulation of glial fibrillary acidic protein. The proNGF was clearly localized in both exosome-like vesicles and cytoplasm of astrocytes in culture. Electron microscopy confirmed exosome-like vesicles with proNGF-immunoreactivity in diameter sizes of 50-100 nm. Finally, cell culture with lipopolysaccharide (LPS) experiment indicated increasing expression and release of proNGF in the astrocytes with LPS exposure. This study demonstrated that reactive astrocytes increased proNGF expression after spinal cord injury, also suggesting involvement of exosome-like proNGF transport or release in triggering neuronal apoptosis and aggravating progression of spinal cord injury.
