Abstract
Trimethyltin chloride is a highly toxic substance, which is absorbed through respiratory tract, skin and digestive tract, with central nervous system injury as the main clinical manifestations, and can be accompanied by damage to various organs. In this paper, the treatment process of 3 patients with acute trimethyltin chloride poisoning was reviewed, and their clinical manifestations, auxiliary examination, diagnosis and treatment were analyzed. Three patients were misdiagnosed as mental abnormality, encephalitis, and hepatic encephalopathy in different hospitals in the early stage of medical treatment, suggesting that clinicians should pay attention to the occupational contact history of poisoned patients and conduct toxicant detection in time to avoid misdiagnosis and mistreatment.

Abstract
Previously, liver lesions in cirrhosis were considered irreversible, especially because the condition aggravated gradually after entering the decompensated phase, thus making it difficult to return to the compensated phase. At present, more and more evidence shows that some patients with decompensated liver cirrhosis can be recompensated after the cause is controlled and complications are managed. This article explores the research progress related to LC reversal and recompensation from three aspects: liver histopathology, liver function, and clinical complications.

Abstract
SOX2 is a transcription factor involved in multiple stages of embryonic development. In related reports, SOX2 was found to be abnormally expressed in tumor tissues and correlated with clinical features such as TNM staging, tumor grade, and prognosis in patients with various cancer types. In most cancer types, SOX2 is a tumor-promoting factor that regulates tumor progression and metastasis primarily by maintaining the stemness of cancer cells. In addition, SOX2 also regulates the proliferation, apoptosis, invasion, migration, ferroptosis and drug resistance of cancer cells. However, SOX2 acts as a tumor suppressor in some cases in certain cancer types, such as gastric and lung cancer. These key regulatory functions of SOX2 involve complex regulatory networks, including protein-protein and protein-nucleic acid interactions through signaling pathways and noncoding RNA interactions, modulating SOX2 expression may be a potential therapeutic strategy for clinical cancer patients. Therefore, we sorted out the phenotypes related to SOX2 in cancer, hoping to provide a basis for further clinical translation.

Abstract
The existing dentin bonding systems based on acid-etching technique lead to the loss of both extrafibrillar and intrafibrillar minerals from dentin collagen, causing excessive demineralization. Because resin monomers can not infiltrate the intrafibrillar spaces of demineralized collagen matrix, degradation of exposed collagen and resin hydrolysis subsequently occur within the hybrid layer, which seriously jeopardizing the longevity of resin-dentin bonding. Collagen extrafibrillar demineralization can effectively avoid the structural defects within the resin-dentin interface caused by acid-etching technique and improve the durability of resin-dentin bonding, by preserving intrafibrillar minerals and selectively demineralizing extrafibrillar dentin. The mechanism and research progress of collagen extrafibrillar demineralization in dentin bonding are reviewed in the paper.

Abstract
Objective: To understand the clinical characteristics of hospitalized patients with liver cirrhosis, so as to provide theoretical basis for disease diagnosis and treatment, formulation of intervention measures, and improve the level of disease diagnosis and treatment. Methods: Hospitalized patients who were initially diagnosed with liver cirrhosis at Peking University First Hospital from August 2017 to December 2018 were selected retrospectively as the research objects. Liver cirrhosis demographic data, etiology, severity classification, incidence of complications, diagnosis and prognosis were recorded. Statistical analysis was performed using SPSS software. Results: Among all liver cirrhosis cases, there were 291 males and 209 females, with a male-to-female ratio of 1.4:1 and an age of 59.5±12.9 years as at August 2017 to December 2018. HBV infection, alcoholic liver disease, and autoimmune liver diseases were the most common etiology of liver cirrhosis. HBV infection alone, HBV infection combined with other factors, alcoholic liver disease alone, alcoholic liver disease combined with other factors, autoimmune liver disease alone, and autoimmune liver disease combined with other factors were presented in 163 (32.6%), 57 (11.4%), 47 (9.4%), 63 (12.6%), 85 (17.0%), and 22 (4.4.0%) cases, respectively. Ascites (221 cases, 44.2%), followed by esophagogastric varices (214 cases, 42.8%), and other including hypersplenism (137 cases), liver cancer (126 cases), upper digestive system tract hemorrhage (66 cases), hepatic encephalopathy (40 cases), infection (37 cases), portal vein thrombosis (23 cases), hepatorenal syndrome (20 cases) were the most common complications. The most common site of infection was the abdominal cavity (20 cases), accounting for 54.1%; followed by respiratory tract infection (8 cases), accounting for 21.6% in patients with liver cirrhosis with concurrent infection. Among them, there were 32 cases of bacterial infection alone, one case of bacterial infection combined with fungal infection, one case of bacterial infection combined with viral infection, and three cases of unknown pathogens. There were 69 cases in Child Pugh grade C, and the average hospitalization times were 12.6 days in terms of prognosis. There were total seven cases of death, of which five cases were due to upper gastrointestinal hemorrhage and two due to hepatic encephalopathy. Conclusion: HBV infection, ascites, and upper gastrointestinal bleeding were the most common etiologies, complications, and causes of death in patients with liver cirrhosis at our hospital.

Abstract
Epstein-Barr virus (EBV) infection is closely associated to liver injury with diverse clinical features in adolescents and adults. It is often manifested as infectious mononucleosis syndrome, sometimes causing self-limited acute hepatitis, with mild to moderate elevation of liver transaminases, and relative increase in age-related conditions. EBV infection can also cause cholestatic hepatitis, with elevated alkaline phosphatase and γ-glutamyltransferase as the main manifestations, accompanied by varying degrees of jaundice. A small number of patients with severe EBV infection may experience liver failure, and if left untreated in time, it may lead to high mortality. In addition, EBV infection is also associated with chronic hepatitis, liver cirrhosis, autoimmune liver disease, etc.

Abstract
Objective: To investigate the effect of programmed death receptor (PD)-1 antibody therapy in patients with hepatitis B-associated liver cancer. Methods: Data of 29 chronically infected HBV patients with liver cancer who received PD-1 antibody combined with tyrosine kinase inhibitor in the Department of Infectious Diseases of the Fifth Medical Center of PLA General Hospital from March 2020 to January 2021 were selected. At the same time, all of the above-mentioned hepatitis B virus (HBV) patients were treated with nucleos(t)ide analogues. Patients clinical diagnostic data, laboratory test results, tumor response and the incidence of adverse reactions were collected retrospectively to understand the overall safety, therapeutic anti-tumor effect, HBV changes condition and the correlation between HBV changes and anti-tumor PD-1 antibody efficacy, high viral load treatment condition, and HBV reactivation safety issues. Statistical analysis was performed by non-parametric rank sum test. Results: Therapeutic anti-tumor effect and safety profile were good in patients. The complete remission rate was reached 27.6%. Adverse reactions were mostly mild, and the incidence of serious adverse reactions was low. After 12 weeks of follow-up, HBV DNA and hepatitis B surface antigen (HBsAg) was quantitatively decreased (P < 0.05). HBV DNA and HBsAg were decreased more significantly in patients with progressive disease (PD), stable disease (SD) and partial response (PR) (P < 0.05). Five patients with HBV DNA ≥ 10(4) IU/ml had responded well to the tumor treatment without serious adverse reactions. One patient had a slight increase in HBV DNA and alanine aminotransferase, while there was no HBV reactivation and correlated liver damage. Conclusion: Patients with HBV-associated liver cancer who received combined therapy have good anti-tumor efficacy and safety profile. PD-1 treatment has a certain effect on HBV. Compared with non-responders, patients with tumor response have better antiviral treatment efficacy. The safety of treatment in patients with high viral load is manageable, and there are no safety issues related to HBV reactivation.

Abstract
BACKGROUND Rectal subepithelial lesions (SELs) are commonly seen in endoscopic examination, generally manifested as bumps with a smooth surface. Precise preoperative diagnoses for rectal SELs are difficult because abnormal tissues are not easily to be obtained by regular endoscopic forceps biopsy. Traditional guidance modalities of preoperative biopsy, including endoscopic ultrasound, computed tomography, and transabdominal ultrasound, are often unsatisfactory. An updated, safe, and effective biopsy guidance method is required. We herein report a new biopsy guidance modality—endorectal ultrasound (ERUS) combined with contrast-enhanced ultrasound (CEUS).
CASE SUMMARY A 32-year-old woman complained of a mass inside the rectovaginal space for 9 years, which became enlarged within 1 year. A rectal SEL detected by endoscopy was suspected to be a gastrointestinal stromal tumor or exophytic uterine fibroid. Pathological diagnosis was difficult because of unsuccessful transabdominal core needle biopsy with insufficient tissues, as well as vaginal hemorrhage. A second biopsy was suggested after multiple disciplinary treatment discussion, which referred to a transperineal core needle biopsy (CNB) guided by ERUS combined with CEUS. Adequate samples were procured and rectal gastrointestinal stromal tumor was proved to be the pathological diagnosis. Imatinib was recommended for first-line therapy by multiple disciplinary treatment discussion. After the tumor shrunk, resection of the rectal gastrointestinal stromal tumor was performed through the posterior vaginal wall. Adjuvant therapy was applied and no recurrence or metastasis has been found by the last follow-up on December 13, 2019.
CONCLUSION Transperineal CNB guided by ERUS and CEUS is a safe and effective preoperative biopsy of rectal SELs yet with some limitations.

Abstract
Objective: A Meta-analysis was used to evaluate the high frequency hearing loss detection rate, its area and time distributions in occupational noise exposed workers in China to provide evidence for the prevention and control of occupational noise-induced deafness. Methods: From February to April 2020, the number of hearing tests and the number of binaural high frequency average hearing threshold ≥40 dB of workers exposed to noise in key occupational disease monitoring and occupational health risk assessment project in China was collected from China National Knowledge Infrastructure (CNKI) , VIP database and PubMed database. The retrieval time was set from the establishment of the database to February 28, 2020. The R 3.6.2 software was used to calculate the pooled high frequency hearing loss detection rate. Results: A total of 28 studies, included 34 data and 1259571 occupational noise exposed workers, were enrolled. The articles covered 16 provinces in 2015-2018. The pooled high frequency hearing loss detection rate in occupational noise exposed workers was 9.45% (95%CI: 7.64%-11.64%) . The high frequency hearing loss detection rate (10.54%) was higher in 2018 than other years (2017: 10.17%, 2016: 9.21%, 2015: 7.88%) . The high frequency hearing loss detection rate (12.23%) was higher in central China than in eastern (10.21%) , western (7.91%) and north-eastern (5.21%) China. Conclusion: The overall high frequency hearing loss detection rate in occupational noise exposed workers is generally high in China. It is important to strengthen the hearing protection in occupational noise exposed workers to facilitate the occupational noise-induced deafness prevention and control in China.

Abstract
Liver cirrhosis is the final stage of many chronic liver diseases, and is still a heavy disease burden. The proportion of liver cirrhosis caused by the hepatitis B virus is declining, while that caused by the non-alcoholic fatty liver disease (metabolic-associated fatty liver disease) is rising. Several predictive models and techniques such as transient elastography have been used for the early non-invasive evaluation of liver cirrhosis. Effective etiological treatment and complication management are the possible key to reverse and recompense liver function during liver cirrhosis treatment. In recent years, the effectiveness and availability of anti-hepatitis B and C virus drugs have been significantly improved, which provides the basis for effective etiological treatment of liver cirrhosis. However, there is still a lack of etiological treatment measures for non-alcoholic fatty liver disease. Therefore, in addition to focusing on common complications, we should also manage "rare" complications. This article reviews the changes in epidemiological characteristics, the update of the natural history concepts, diagnostic evaluation methods, and the treatment measures for liver cirrhosis.

Abstract
Objective: To explore the risk factors of overt hepatic encephalopathy (OHE) in patients with liver cirrhosis. Methods: A retrospective study was designed. Patients with liver cirrhosis combined with /without OHE who were hospitalized to our hospital during the same period were selected as the case/control group. Clinical and laboratory data of both groups of patients were compared to analyze the risk factors affecting the occurrence of OHE. SPSS software was used for statistical analysis. A t-test or rank-sum test was used to compare the measurement data. Chi-square test or Fisher's exact probability method was used to compare the count data. Logistic regression was used for multivariate analysis. Results: A total of 500 patients with liver cirrhosis diagnosed in our hospital from August 2017 to December 2018 were selected as the case group, and 40 cases with cirrhosis without OHE who were hospitalized during the same period were randomly selected as the control group. The gender composition and age of the case and control group were comparable. Viral hepatitis (mainly hepatitis B) was the main etiology of liver cirrhosis in both groups. There were 52.5% patients in the case group and 57.5% patients in the control group, respectively. Alcoholic liver disease, autoimmune liver disease and so on were the other included causes. With regard to blood biochemical indicators, the serum creatinine levels of both groups were comparable, but in the case group, the serum total bilirubin level was higher (34.30 μmol / L vs. 18.65 μ mol/L, Z = -3.185, P < 0.05), while the serum sodium level was lower (137.00 mmol/L vs. 140.08 mmol/L, Z = -2.348, P < 0.05), and the prothrombin time was longer (14.60 s vs. 12.20 s) s. 078, P < 0.05), and international normalized ratio (1.33 vs. 1.07, Z = - 5.632, P < 0.05), and serum albumin level (30.6 g/L vs. 35.6 g/L, t = 3.386, P < 0.05) was lower. In terms of complications, patients in the case group had a higher proportion of combined gastrointestinal bleeding (30.0% vs. 10.0%, χ(2) = 5.000, P < 0.05), ascites (87.5% vs. 30.0%, χ(2) = 27.286, P < 0.05) and secondary infection (32.5% vs. 10.0%, χ(2) = 7.813, P < 0.05). In terms of severity classification, the proportion of Child-Pugh C in the case group was higher (62.5% vs. 10.0%, χ(2) =26.593, P < 0.05). In terms of outcome, there were 3 deaths in the case group and no deaths in the control group. Multivariate analysis showed that Child-Pugh class C (OR = 12.696), and combined ascites (OR = 10.655) were an independent risk factor for OHE in patients with liver cirrhosis. Conclusion: Our single-center retrospective clinical study shows that patients with cirrhosis combined with OHE are more critical and have more complications. In order to promptly diagnose and treat OHE, more attention should be paid to patients with combined ascites and Child-Pugh class C.

Abstract
BACKGROUND Trocar site hernia (TSH) is a rare but potentially dangerous complication of laparoscopic surgery, and the drain-site TSH is an even rarer type. Due to the difficulty to diagnose at early stages, TSH often leads to a delay in surgical intervention and eventually results in life-threatening consequences. Herein, we report an unusual case of drain-site TSH, followed by a brief literature review. Finally, we provide a novel, simple, and practical method of prevention.
CASE SUMMARY A 54-year-old female patient underwent laparoscopic subtotal hysterectomy and bilateral adnexectomy for uterine fibroids 8 d ago in another hospital. She was admitted to our hospital with a 2-d history of intermittent abdominal pain, nausea, vomiting, and abdominal enlargement with an inability to pass stool and flatus. The emergency computed tomography scan revealed the small bowel herniated through a 10 mm trocar incision, which was used as a drainage port, with diffuse bowel distension and multiple air-fluid levels with gas in the small intestines. She was diagnosed with drain-site strangulated TSH. The emergency exploratory laparotomy confirmed the diagnosis. A herniorrhaphy followed by standard intestinal resection and anastomosis were performed. The patient recovered well after the operation and was discharged on postoperative day 8 and had no postoperative complications at her 2-wk follow-up visit.
CONCLUSION TSH must be kept in mind during the differential diagnosis of post-laparoscopic obstruction, especially after the removal of the drainage tube, to avoid the serious consequences caused by delayed diagnosis. Furthermore, all abdomen layers should be carefully closed under direct vision at the trocar port site, especially where the drainage tube was placed. Our simple and practical method of prevention may be a novel strategy worthy of clinical promotion.

Abstract
Objective: To investigate the effects of metastasis associated gene 1 (MTA1) expression on the proliferation and apoptosis of human esophageal cancer Eca109 cells. Methods: MTA1 siRNA was transfected into human esophageal cancer Eca109 cells, and the control group and blank group were set up. The expression of MTA1 in Eca109 cells with different treatment was detected by real-time fluorescent quantitative PCR (RT-PCR) and western blot. The proliferation of Eca109 cells was detected by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2H tetrazolium bromide (MTT) assay. The cloning formation ability of Eca109 cells was detected by plate cloning assay. The apoptosis of Eca109 cells were detected by flow cytometry. The expression of proliferating cell nuclear antigen (PCNA) and apoptosis-related proteins, including cleaved caspase-3 and total caspase-3 protein in Eca109 cells were detected by western blot. Results: After 48 hours of transfection, RT-PCR result showed that the relative expression levels of MTA1 mRNA in Eca109 cells in the blank group, control group, and siRNA group were 1.00±0.10, 0.98±0.09 and 0.21±0.03, respectively. The expression of MTA1 mRNA in siRNA group was significantly inhibited (P<0.05), while no significant difference of MTA1 mRNA expression between the blank group and the control group has been found (P>0.05). Western blot results were consistent with those of RT-PCR. MTT array results showed that, compared with the blank group and transfection group, the absorbance values of Eca109 cells in siRNA group were dramatically reduced at 48, 72, and 96 h (all P<0.05). There were no significant differences of absorbance values between the blank group and the control group at 48, 72, and 96 h (all P>0.05). The results of the plate colony formation test showed that the number of colony formation in the blank group and control group were 58.64±6.86 and 60.02±7.04, respectively, significantly higher than 18.10±3.16 in siRNA group (P<0.05), while there was no significant difference between the blank group and control group (P>0.05). Flow cytometry results showed that the apoptosis rates in the blank group and control group were (2.13±0.54)% and (2.27±0.61)%, respectively, significantly lower than (32.61±5.28)% in siRNA group (P<0.05), while there was no significant difference between blank group and control group (P>0.05). Western blot results showed that the expression of PCNA protein was down-regulated while cleaved caspase-3 protein expression was upregulated in siRNA group, compared to the control group and blank group (P<0.05). Conclusions: Inhibition of MTA1 expression can inhibit the proliferation of Eca109 cells and induce apoptosis. This process may be related to the down-regulation of PCNA protein expression and activation of caspase-3 protein expression.

Abstract
The rapid development of computer technologies brings us great changes in daily life and work. Artificial intelligence is a branch of computer science, which is to allow computers to exercise activities that are normally confined to intelligent life. The broad sense of artificial intelligence includes machine learning and robots. This article mainly focuses on machine learning and related medical fields, and deep learning is an artificial neural network in machine learning. Convolutional neural network (CNN) is a type of deep neural network, that is developed on the basis of deep neural network, further imitating the structure of the visual cortex of the brain and the principle of visual activity. The current machine learning method used in medical big data analysis is mainly CNN. In the next few years, it is the developing trend that artificial intelligence as a conventional tool will enter the relevant departments of medical image interpretation. In addition, this article also shares the progress of the integration of artificial intelligence and biomedicine combined with actual cases, and mainly introduces the current status of CNN application research in pathological diagnosis, imaging diagnosis and endoscopic diagnosis for gastrointestinal diseases.

Abstract
Plesiomonas shigelloides is a common pathogen of aquatic animals and can pose a certain hazard to aquaculture. Here, we aimed to develop a loop-mediated isothermal amplification (LAMP) method for the visual detection of P. shigelloides to aid the diagnosis of infections caused by this pathogen in aquatic animals. We used LAMP to amplify P. shigelloides DNA and combined it with calcein or nucleic acid dipstick assay (NADA) to visualize the amplified products. The optimal LAMP amplification temperature was 64°C, and the reaction lasted for 50 min. The limit of detection of recombinant plasmids containing the target gene using the LAMP method was 2·0 × 102 copies per μl, which is ten times higher than that using conventional polymerase chain reaction (PCR). LAMP products could be visualized without agarose gel electrophoresis. We tested 85 fish specimens using the established LAMP method and conventional PCR. The detection rate was 42·4% using the LAMP method and 34·1% using conventional PCR. Based on our results, the LAMP method combined with calcein or NADA is a rapid, specific, sensitive and accurate method for visual detection of fish-derived P. shigelloides and can be used for the laboratory diagnosis of infections caused by it. SIGNIFICANCE AND IMPACT OF THE STUDY: The combination of loop-mediated isothermal amplification (LAMP) and calcein and nucleic acid dipstick assay (NADA) provided a rapid, specific and sensitive method for detecting Plesiomonas shigelloides, which is an important pathogen that causes diseases in aquatic animals worldwide. In the present study, the LAMP method showed a higher detection rate than conventional PCR for P. shigelloides using templates from 85 fish specimens. Thus, the LAMP method could be a reliable and convenient tool for diagnosing diseases in aquatic animals in the laboratory.

Abstract
Objective: To compare the features of a modified WHO/UCLA AVLT performance in the cognitive normal, amnestic mild cognitive impairment (aMCI) and mild Alzheimer's disease (mild AD) patients. Method: A total of 105 cases of cognitivenormal (CN), 48 aMCI and 50 mild AD patients were included between 2016 and 2018. All subjects undertook detailed neuropsychological tests and brain MRI/CT scan. Results: The total score of five learning trials in CN, aMCI and AD groups were 53.9±6.9, 34.6±8.3 and 23.7±6.2, respectively (P<0.001). The score of 20-min delay recallwere 12.5±1.6, 4.3±3.0 and 0.6±1.0, respectively (P<0.001) in three groups. The score of cued recall were 13.0±1.4, 7.0±2.4 and 2.6±2.0, respectively (P<0.001). The score of 20-min delay recall had the largest effect sizes between CN and aMCI groups (Cohen'd=3.8, 95%CI,3.3-4.4), and CN and mild AD groups (Cohen'd=8.1, 95%CI 7.1-9.1). Cued recall had the largest effect size between aMCI and mild AD groups (Cohen'd=2.04, 95%CI 1.5-2.5). The scores of learning total score, 20-min delay recall, cued recall and recognition had the strong relationships with the scores of mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) , but obtaining moderate relationships with Boston naming test and trail making test (TMT) and weak relationships with digit span and figure copy. Age and education had no relationship with the main indices of this modified AVLT. Conclusions: The modified WHO/UCLA AVLT is still an age and education fair test to assess memory domain function. Qualitative analysis of AVLT profiles may be useful to differentiate the CN, aMCI and mild AD in Chinese sample.

Abstract
Background As an aggressive hematological malignancy, acute myeloid leukemia (AML) remains a dismal disease with poor prognosis. Long non-coding RNAs (lncRNAs) have been widely reported to be involved in tumorigenesis of AML. Here, we define an important role of lncRNA HOTAIR in AML in relation to HOXA5 methylation. Methods Firstly, the expression of HOTAIR was examined in AML samples and cells collected. Next, gain- or loss-of function experiments were conducted in AML cells to explore the effect of HOTAIR on AML. Then, relationship among HOXA5 promoter methylation, HOTAIR and Dnmt3b was measured. Expression of HOXA5 and cell proliferation/apoptosis-related genes was also detected. A last, in vivo assay was performed to assess the tumor formation in nude mice in order to explore the roles of HOTAIR and HOXA5 in cell apoptosis and proliferation. Results LncRNA HOTAIR was found to be upregulated in AML cells and tissues. With silencing of HOTAIR and overexpression of HOXA5, AML cell proliferation was decreased while the apoptosis was induced. Furthermore, HOTAIR was observed to recruit Dnmt3b and to increase HOXA5 promoter methylation. Moreover, silencing HOTAIR and upregulating HOXA5 were found to induce apoptosis and reduce proliferation of AML cells in vivo. Conclusion Our findings highlight the anti-tumor ability of HOTAIR silencing in AML, suggesting that silencing HOTAIR was able to inhibit AML progression through HOXA5 promoter demethylation by decreasing Dnmt3b.

Abstract
RATIONALE Behçet's disease (BD) is a chronic immune-mediated inflammatory disorder involving multiple organ systems. In BD, intestinal ulcers can present as a refractory lesion capable of perforation, which makes the choice of treatment difficult. PATIENT CONCERNS A 34-year-old male who was diagnosed with intestinal BD and suffered with an ileocecal perforation. He underwent surgery for an ileostomy and was given corticosteroids as treatment. However, the ulcerative lesion remained resistant to the therapy that was provided which delayed the closure operation. DIAGNOSIS Intestinal BD with severe post-operative complication. INTERVENTIONS A course of adalimumab (ADa) therapy was started. Subsequently surgery was performed. And ADa and thalidomide were used as a maintenance therapy. OUTCOMES In this case, a course of ADa therapy was given which healed the intestinal ulcers and allowed us to successfully perform the closure operation. LESSONS This case indicates that ADa may be an effective treatment option in future cases, minimizing complications and allowing the closure operation to be performed successfully.

Abstract
Objective: To study the influence of two-wall bone defect on periodontal ligament stresses under normal occlusal forces, and to analyze the influence of depth and width of bone defect to periodontal ligament stresses. Methods: Three-dimensional finite element models of teeth, periodontal ligament and alveolar bone were created based on cone beam CT images. Proximal two-wall bone defect with different depths (bone defect occupies one third, two thirds, and full length of root) and widths (bone defect occupies one fourth, two fourths, three fourths and full width of buccal lingual width) were simulated by modifying the elastic modulus of elements within defect areas. Occlusal forces with magnitudes of half of the maximum occlusal forces were applied to the model at an angle of 45° to the long axis of tooth, and equivalent stresses of periodontal ligament were analyzed. Results: In the model of no bone defect, the equivalent stresses of periodontal ligament of incisors, canines, premolars and molars were 2.88, 2.31, 8.67 and 7.53 MPa respectively. The equivalent stresses of periodontal ligament increased with the enlargement of depth and width of bone defect. The equivalent stresses of periodontal ligament with maximum bone defect in both depth and width for incisors, canines, premolars and molars were 4.47, 3.62, 11.66 and 8.72 MPa respectively. In the model of width of bone defect was consistent and bone defect develops vertically, the increments of equivalent stresses of periodontal ligament were significantly greater in the early stage bone defect model (from no defect to one third of root length bone defect) than that in the later stage bone defect model (from two thirds to full length of root length bone defect). In the model of bone defect depth was consistent and bone defect develops transversely, the increments of equivalent stresses of periodontal ligament in the early stage bone defect model (from no defect to one fourth of buccal lingual width bone defect) were significantly smaller than that in the later stage bone defect model (from three fourths to full width of buccal lingual width bone defect). Conclusions: Bone defect with shallow depth and that with large width would increase periodontal ligament stresses. Therefore, more attention should be paid to occlusion evaluation and adjustment for teeth with shallow and wide two-wall bone defect.

Abstract
The lymph node ratio (LNR) (i.e. the number of metastatic lymph nodes divided by the number of totally resected lymph nodes) has recently emerged as an important prognostic factor in colorectal cancer (CRC). However, the tumor node metastasis (TNM) staging system for colorectal cancer does not consider it as a prognostic parameter. Therefore, we conducted a meta-analysis to evaluate the prognostic role of the LNR in node positive CRC. A systematic search was performed in PubMed, Embase and the Cochrane Library for relevant studies up to November 2015. As a result, a total of 75,838 node positive patients in 33 studies were included in this meta-analysis. Higher LNR was significantly associated with shorter overall survival (OS) (HR = 1.91; 95% CI 1.71–2.14; P = 0.0000) and disease free survival (DFS) (HR = 2.75; 95% CI: 2.14–3.53; P = 0.0000). Subgroup analysis showed similar results. Based on these results, LNR was an independent predictor of survival in colorectal cancer patients and should be considered as a parameter in future oncologic staging systems.

Abstract
Essentials M1/M2 imbalance is involved in many autoimmune diseases, and could be restored. The expressions and functions of M1 and M2 were investigated in an in vitro culture system. A preferred M1 polarization is involved in the pathogenesis of immune thrombocytopenia (ITP). High-dose dexamethasone or all-trans-retinoic acid restores M1/M2 balance in ITP patients. SUMMARY Background Immune thrombocytopenia (ITP) is an autoimmune disorder. Deficiency of immune tolerance in antigen-presenting cells and cross-communication between antigen-presenting cells and T cells are involved in the pathogenesis of ITP. Macrophages can polarize into proinflammatory M1 or anti-inflammatory M2 phenotypes in response to different environmental stimuli, and have diverse immunologic functions. Objectives To investigate the M1/M2 imbalance in ITP and whether high-dose dexamethasone (HD-DXM) or all-trans-retinoic acid (ATRA) could restore this imbalance. Methods The numbers of M1 and M2 macrophages in the spleens of ITP patients and patients with traumatic spleen rupture were analyzed by immunofluorescence. Monocyte-derived macrophages were cultured and induced with cytokines and drugs. The expression of M1 and M2 markers and functions of M1 and M2 macrophages before and after modulation by HD-DXM or ATRA were evaluated with flow cytometry and ELISA. Results There was preferred M1 polarization in ITP spleens as compared with healthy controls. Monocyte-derived macrophages from ITP patients had increased expression of M1 markers and impaired immunosuppressive functions. Either HD-DXM or ATRA corrected this imbalance by decreasing the expression of M1 markers and increasing the expression of M2 markers. Moreover, HD-DXM-modulated or ATRA-modulated macrophages suppressed both CD4+ and CD8+ T-cell proliferation and expanded CD4+ CD49+ LAG3+ type 1 T-regulatory cells. HD-DXM or ATRA modulated macrophages to shift the T-cell cytokine profile towards Th2. Treating patients with HD-DXM or ATRA revealed that macrophages induced from responders showed a predominant M2-like phenotype and immunosuppressive function. Conclusions Aberrant macrophage polarization is involved in the pathogenesis of ITP. Either HD-DXM or ATRA is able to correct this imbalance.

Abstract
PURPOSE Alkaloids derived from Rhizoma Coptis (RC) has been widely applied to clinical treatments in China. However, the toxicity of RC and the alkaloids from RC remained controversial. The research is designed to clarify the cardiotoxic compounds found in RC. METHODS In this study, the real-time cellular analysis cardio system and the high-content analysis were applied to monitor the function of cardiomyocytes (CMs) in the treatment of nine alkaloids in RC. Luciferase-coupled adenosine triphosphate (ATP) assay was used to detect cell viability. RESULTS The results showed that berberine, palmatine, berbamine, and oxyberberine were cardiotoxic, which resulted in arrhythmia and cardiac arrest on CMs in a time- and dose-dependent manner. Meanwhile, berbamine and oxyberberine caused shrinkage and detachment on CMs at 10 μM. Cytotoxicity was induced by these two compounds with decline in cell index and ATP depletion. Cardiotoxicity or cytotoxicity was not observed in the other five alkaloids within 10 μM. CONCLUSION For the first time, the cardiotoxicity of the nine alkaloids was evaluated to clarify the cardiotoxic components in RC. Furthermore, the experimental evidences were provided to support the safety of drug application.

Abstract
Objective: To evaluate the efficacy of large spot indirect ophthalmoscopy laser alone or combined with systemic chemotherapy in the treatment of early and middle stage retinoblastoma. Methods: Retrospective series case study. Clinical data of 21 patients (22 eyes) who were diagnosed as retinoblastoma (RB) in Peking University People's Hospital from March 2009 to August 2014 were collected. Medical and family history, ocular ultrasound, orbital and cranial MRI or CT examination of RB Children were detailed recorded. Ocular examination and laser treatment were performed under general anesthesia, once every 3-4 weeks until the tumor was under control. The observation period was at least 3 months after the last treatment. The ocular examination included intraocular pressure measurement, anterior segment and fundus examination and the fundus photography with Retcam. Laser therapeutic instrument was large spot indirect ophthalmoscopy laser of 810nm wavelength. Results: Of the 21 children, 16 were male and 5 were female. The range of age was 3 to 82 months averaged 17.3 months. Among 22 eyes, four with small tumor, eight with medium tumor, and ten with large tumor. Two eyes underwent laser treatment only and 20 eyes underwent laser treatment combined with systemic chemotherapy. During the average observation period of 33.9 months, 15 tumors were treated successfully, but 7 failed. The total success rate was 68.2%. The number and success rate of small, medium and large tumor eyes were 4 (100%), 5 (62.5%) and 5 (50%), respectively. There was one case of tumor brain metastases, and the classification of contralateral eye of the child was E phase. COMPLICATIONS Iris burns happened in one eye, obvious vitreous proliferation in one eye and mild vitreous hemorrhage occurred in two eyes, which did not affect the treatment of laser. However, obvious tumor hemorrhage happened in two eyes and affected laser therapy. There was no complicated cataract, iatrogenic retinal hole and tumor intravitreal implant caused by laser blasting effect. Conclusions: Indirect ophthalmoscope laser in 810-nm diode laser with large-spot alone or combined with systemic chemotherapy may be effective treatment for retinoblastoma in earlier than stage C of international classification. It is suitable for large and multiple retinoblastoma.(Chin J Ophthalmol, 2016, 52: 745-748).

Abstract
OBJECTIVE To decipher the cognitive and linguistic feature of logopenic variant primary progressive aphasia (lv-PPA) and nonfluent variant primary progressive aphasia (nfv-PPA) and to explore the extent to which cognitive and language impairment contribute to the dysfunction of activity of daily living(ADL). METHODS Seven lv-PPA and five nfv-PPA were enrolled in memory clinic of Xuanwu Hospital, Capital Medical University from January 2015 to January 2016 accordig to the international consensus criteria for PPA and its three subtypes. 20 age-matched normal controls (NC) were included. Both the patients and the NC completed a battery of neuropsychological test, lingusitic test and brain magnetic resonance imaging. All the patients conducted (11)C Pittsburgh compound B (PiB) PET imaging. RESULT Lv-PPA patients were characterized by deficits in lexical retrieval and long sentenses repetition, while nfv-PPA were with motor speech apraxia and phonetic distortion. Compared with nfv-PPA, lv-PPA patient displayed more severe cognitive deficit with younger onset of age (56±5 vs 61±5, P<0.05) , rapid decline of MMSE score within 1.5 years and pariental cortex dysfunctions such as ideomotor praxis, Gerstmann syndrome and contructional apraxia. Correlation analysis indicated that there was more significant association between pariental cortex dysfunction and ADL/mini-mental state examination(MMSE) than that of language deficit(r=-0.868, r=-0.922; r=0.312, r=-0.257). All seven lv-PPA were PiB-PET positive and five nfv-PPA were negative. CONCLUSION This study enriched the chinical and linguistic characterization of lv-PPA and nfv-PPA, which has implication for diagnosis, disease management and treatment for clinicians.

Abstract
The incidence of colorectal cancer (CRC) in young patients (≤50 years of age) appears to be increasing. However, their clinicopathological characteristics and survival are controversial. Likewise, the biomarkers are unclear. We used the West China (2008-2013, China), Surveillance, Epidemiology, and End Results program (1973-2011, United States) and Linköping Cancer (1972-2009, Sweden) databases to analyse clinicopathological characteristics, survival and multiple biomarkers of young CRC patients. A total of 509,934 CRC patients were included from the three databases. The young CRC patients tended to have more distal location tumours, fewer tumour numbers, later stage, more mucinous carcinoma and poorer differentiation. The cancer-specific survival (CSS) of young patients was significantly better. The PRL (HR = 12.341, 95% CI = 1.615-94.276, P = 0.010), RBM3 (HR = 0.093, 95% CI = 0.012-0.712, P = 0.018), Wrap53 (HR = 1.952, 95% CI = 0.452-6.342, P = 0.031), p53 (HR = 5.549, 95% CI = 1.176-26.178, P = 0.045) and DNA status (HR = 17.602, 95% CI = 2.551-121.448, P = 0.001) were associated with CSS of the young patients. In conclusion, this study suggests that young CRC patients present advanced tumours and more malignant pathological features, while they have a better prognosis. The PRL, RBM3, Wrap53, p53 and DNA status are potential prognostic biomarkers for the young CRC patients.

Abstract
The present study aimed to assess the efficacy of surgery and adjuvant therapy in older patients (age≥70 years) with colorectal cancer (CRC). Older CRC patients are under-represented in available clinical trials, and therefore their outcomes after receiving surgery and adjuvant therapy are unclear. From two prospective Swedish databases, we assessed a cohort of 1021 patients who underwent curative surgery for stage I, II, or III primary CRC, with or without adjuvant chemotherapy/radiotherapy. Of the patients with colon cancer (n=467), 182 (39%) were aged <70 years, 162 (35%) aged 70 to 80 years, and 123 (26%) were aged ≥80 years. Of rectal cancer patients (n=554), 264 (48%) were aged <70 years, 234 (42%) aged 70 to 80 years, and 56 (10%) aged ≥80 years. Older patients with either colon or rectal cancer had higher comorbidity than did younger patients. Older patients with colon cancer had equivalent postoperative morbidity and 30-day mortality to younger patients. Rectal cancer patients aged ≥80 years had a higher 30-day mortality than younger patients (odds ratio [OR], 2.37; 95% confidence interval [CI], 1.6-4.55; P=0.03). For either colon or rectal cancer, adjuvant chemotherapy compromised the 5-year overall survival (OS) of older patients with stage II disease and had no effect on those with stage III disease. Receiving adjuvant chemotherapy was a poor factor of OS for older patients with either colon (HR 1.88, 95% CI: 1.20-4.35, P=0.03) or rectal cancer (HR 1.72, 95% CI: 1.05-2.26, P=0.004). Preoperative short-course radiotherapy improved both OS and local control for older patients with stage III rectal cancer and had no effect on those with stage II disease. Radiotherapy was a favorable factor for the OS of the older patients with rectal cancer (HR 0.42, 95% CI: 0.21-3.57, P=0.01). In conclusion, Older CRC patients had equal safety of surgery as younger patients, except rectal cancer patients aged ≥80 years that had a higher mortality. Adjuvant 5FU-based chemotherapy did not benefit older CRC patient, while neoadjuvant radiotherapy improved the prognosis of older patients with stage III rectal cancer.

Abstract
INTRODUCTION K-ras gene mutations were common in colorectal patients, but their relationship with prognosis was unclear. OBJECTIVE Verify prognostic differences between patient with and without mutant K-ras genes by reviewing the published evidence. METHOD Systematic reviews and data bases were searched for cohort/case-control studies of prognosis of colorectal cancer patients with detected K-ras mutations versus those without mutant K-ras genes, both of whom received chemotherapy. Number of patients, regimens of chemotherapy, and short-term or long-term survival rate (disease-free or overall) were extracted. Quality of studies was also evaluated. PRINCIPAL FINDINGS 7 studies of comparisons with a control group were identified. No association between K-ras gene status with neither short-term disease free-survival (OR=1.01, 95% CI, 0.73-1.38, P=0.97) nor overall survival (OR=1.06, 95% CI, 0.82-1.36, P=0.66) in CRC patients who received chemotherapy was indicated. Comparison of long-term survival between two groups also indicated no significant difference after heterogeneity was eliminated (OR=1.09, 95% CI, 0.85-1.40, P=0.49). CONCLUSIONS K-ras gene mutations may not be a prognostic index for colorectal cancer patients who received chemotherapy.

Abstract
PURPOSE Recently, microRNA-124 (miR-124) has been demonstrated as a potential tumor suppressor in several types of cancers. However, the role of miR-124 in colorectal cancer remains unclear. This study was aimed at investigating the clinicopathological significance of miR-124 expression in colorectal cancer. METHODS Quantitative real-time PCR was used to analyze miR-124 expression in 96 colorectal cancers and individual-matched normal mucosa samples. The expression of miR-124 was assessed for associations with clinicopathological characteristics using chi-square test. The survival curves were calculated by the Kaplan-Meier method. The influence of each variable on survival was examined by the Cox multivariate regression analysis. RESULTS The miR-124 expression was significantly downregulated in colorectal cancer compared to normal mucosa (P = 0.001). In colorectal cancer, miR-124 decreased expression correlated significantly with the grade of differentiation (P = 0.021). Univariate survival analysis showed that the downregulated miR-124 was significantly correlated with worse prognosis, both in terms of overall survival (P = 0.017) and disease-free survival (DFS) (P = 0.014). Further, the downregulated miR-124 was demonstrated as a prognostic factor for overall survival (hazard ratio, HR = 4.634; 95 % confidence interval, CI, 1.731-12.404; P = 0.002) and DFS (HR = 4.533, 95 % CI 1.733-11.856, P = 0.002), independently of gender, age, location, maximum tumor size, depth of invasion, differentiation, and TNM stage. CONCLUSIONS MiR-124 may play a certain role in the development of colorectal cancer. The downregulation expression of miR-124 is an independent prognostic factor in patients with colorectal cancer.

Abstract
BACKGROUND Open splenectomy and devascularization are effective treatments for cirrhotic patients with severe thrombocytopenia and variceal bleeding. However, it remains controversial whether laparoscopic splenectomy (LS) and devascularization (LSD) can be indicated and beneficial in these patients. OBJECTIVES A systematic review of the efficacy and safety of LS and LSD for patients with liver cirrhosis and portal hypertension was undertaken to clarify controversy about their utilization in such patients. METHODS A systematic search strategy was performed to retrieve relevant studies from PubMed and Embase.com. The literature search and data extraction were independently performed by two reviewers. RESULTS Sixteen articles met the inclusion criteria. The methodology of the identified articles was poor. Six hundred and fifty-one patients, including 478 LS patients and 173 LSD patients, were involved in efficacy and safety evaluations. There was wide variability in the outcome measures between studies. There was only one death in the patients underwent LSD. Reported major complications included post-operative bleeding requiring re-surgery, pancreatic leakage and gastric perforation. Seven studies were identified with comparisons between laparoscopic and open procedures. No meta-analysis was possible because of heterogeneity between studies and lack of randomization. CONCLUSIONS The publications reviewed revealed LS and LSD to be safe and effective in the setting of liver cirrhosis and portal hypertension. From the comparison articles, laparoscopic procedures appear to be superior to open procedures regarding blood loss, hospital stay, complication rate and liver function impairment. However, it is difficult to draw firm statistical conclusions due to lack of high-quality evidence.

Abstract
The aim of the present study to evaluate the application of sentinel lymph node (SLN) pathology in rectal cancer using ex vivo mapping and to investigate the incidence and prognostic value of occult SLN metastasis in routine node-negative specimens. Specimens (n=117) of rectal cancer were examined using a combination of routine pathology and ex vivo SLN mapping. The inspected SLNs were further treated with immunohistochemical staining for occult cancer foci. The log-rank test was used to assess survival. SLNs were examined in 112 of the included specimens with a total number of 212, resulting in an identification rate of 95.7% (112/117). The status of SLNs accurately reflected N stage in 93.8% (105/112) of cases and the sensitivity was 75.6% (31/41) in detecting nodal metastasis. The accuracy of SLN pathology decreased in cancers of more advanced TNM stages (P=0.001). In 74 cases with routine node-negative (N0) disease, SLN micrometastasis (MIC) and isolated tumor cells (ITC) were examined in 9 and 4 cases, while the remaining 61 were regarded as negative (NEG). The log-rank test revealed poorer disease-free and overall survival of the MIC group compared with the NEG group. However, the findings from the ITC group were not significant compared with those from the MIC and NEG groups. In conclusion, ex vivo SLN pathology is practical and accurate in rectal cancer; however, its utility is limited in cases of advanced disease. Immunohistochemically detected SLN micrometastasis in node-negative cases is therefore a predictor of poorer outcome, and may therefore be listed as a marker for adjuvant therapy.

Abstract
BACKGROUND The International Physical Activity Questionnaire (IPAQ-SF) has been validated and recommended as an efficient method to assess physical activity, but its validity has not been investigated in different population subgroups. We examined variations in IPAQ validity in the Hong Kong Chinese population by six factors: sex, age, job status, educational level, body mass index (BMI), and visceral fat level (VFL). METHODS A total of 1,270 adults (aged 42.9 ± SD 14.4 years, 46.1% male) completed the Chinese version of IPAQ (IPAQ-C) and wore an accelerometer (ActiGraph) for four days afterwards. The IPAQ-C and the ActiGraph were compared in terms of estimated Metabolic Equivalent Task minutes per week (MET-min/wk), minutes spent in activity of moderate or vigorous intensity (MVPA), and agreement in the classification of physical activity. RESULTS The overall Spearman correlation (ρ) of between the IPAQ-C and ActiGraph was low (0.11 ± 0.03; range in subgroups 0.06-0.24) and was the highest among high VFL participants (0.24 ± 0.05). Difference between self-reported and ActiGraph-derived MET-min/wk (overall 2966 ± 140) was the smallest among participants with tertiary education (1804 ± 208). When physical activity was categorized into over or under 150 min/wk, overall agreement between self-report and accelerometer was 81.3% (± 1.1%; subgroup range: 77.2%-91.4%); agreement was the highest among those who were employed full-time in physically demanding jobs (91.4% ± 2.7%). CONCLUSIONS Sex, age, job status, educational level, and obesity were found to influence the criterion validity of IPAQ-C, yet none of the subgroups showed good validity (ρ = 0.06 to 0.24). IPAQ-SF validity is questionable in our Chinese population.

Abstract
BACKGROUND/AIMS To study lymph node metastasis and micrometastasis within the mesorectum and lateral pelvic area in lower rectal cancer. METHODOLOGY Specimens of 96 patients, who underwent total mesorectal excision (TME) and lateral lymph node dissection (LLND), were included. RESULTS An average of 19.4 mesorectal lymph nodes were examined. Horizontally, more than 30 percent of involved lymph nodes were located in the outer layer of the mesorectum. Longitudinally, metastasized lymph nodes were harvested from the distal, paratumoral and proximal mesorectum of 6, 42 and 29 specimens, respectively. Fourteen specimens were observed to have circumferential resection margin involvement, while another 3 had micrometastasis. The average amount of harvested lateral pelvic lymph nodes was 12.1. Most (1052/1159) of the lateral nodes were defined as negative. Fourteen and 11 specimens were examined to contain lateral node metastasis and micrometastasis, respectively. Among regions of the lateral pelvic area, middle rectal root (44%), internal iliac (28%) and obturator (20%) were more likely to be involved by cancer spread. CONCLUSIONS Complete excision of the mesorectum is essential for local clearance of lower rectal cancer. Mesorectal margin involvement and lateral metastasis underlined the limitation of single surgical procedure, thus suggesting the significance of neoadjuvant therapy.

Abstract
We isolated a novel strain of Alphaproteobacteria from a patient, who had medical history of chronic rhinitis for more than twenty years and recently experienced local skin abscess and ulcer. He eventually died of multiple organ failure due to multi-antibiotics resistance. We identified the microorganism by 16SrRNA sequencing and found that it belonged to the genus Rhodoplanes. It was named as Rhodoplanes sp. strain ZLJ-0. It is resumed that Rhodoplanes sp. strain ZLJ-0 might be an emerging human pathogen involving in unknown febrile conditions and could cause local infection of any tissues or organs. Differential diagnosis of febrile patients should be conducted in clinical practice and research on emerging pathogens of Alphaproteobacteria should be performed to determine the epidemiology, clinical symptoms and pathogenic features of these pathogens.

Abstract
The effect of 2,2'-dipyridyl (DP) on cerebral vasospasm was investigated in a double-injection rabbit model of subarachnoid haemorrhage (SAH). Thirty-six animals were divided between four groups: control (sham-operated), SAH (model alone), SAH + DP (the SAH model in which DP dissolved in dimethyl sulphoxide [DMSO] was injected once daily for 5 days into the cisterna magna), and SAH + DMSO (the SAH model in which DMSO [vehicle] was injected daily for 5 days). There were significant differences in the basilar artery luminal area, wall thickness, neurological deficit score and vasospasm index between the SAH + DP and SAH groups. There was a significant negative correlation between arterial luminal area and arterial wall thickness, and also between the neurological deficit score and vasospasm index. Cells that were positive for terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labelling (TUNEL) and p53 expression were significantly increased in the SAH + DMSO and SAH groups, but not in the SAH + DP group, versus controls. Thus, DP may attenuate cerebral vasospasm after SAH by suppressing p53-induced apoptosis in the cerebral vessels.
