Abstract
Objective: To explore the predictive value of pulmonary effective arterial elastance (Ea) in patients with heart failure (HF). Methods: This is a retrospective cohort study, which retrospectively included 284 patients with HF who underwent right heart catheterization at Heart Failure Center in Fuwai Hospital between September 2013 and February 2022. Data regarding baseline clinical characteristics, hemodynamic profiles, and prognosis were collected. Ea was calculated as mean pulmonary arterial pressure/stroke volume. Patients were divided into Ea<0.555 group and Ea≥0.555 group according to the median value of Ea (0.555 mmHg/ml, 1 mmHg=0.133 kPa). The primary outcome was the primary clinical event, set as the first occurrence of a series of composite events, including all-cause death, heart transplantation, left ventricular assist device implantation, and HF rehospitalization. Event-free survival was defined as the absence of primary clinical events. Spearman correlation analysis was used to calculate the correlation coefficient between Ea and parameters reflective of right heart function. The Kaplan-Meier analysis was used to compare the different groups for the estimation of outcomes with the log-rank test. We used Cox proportional-hazards regression models to estimate hazard ratios (HR) for primary clinical event. Subgroup analysis was performed based on the age, gender, New York Heart Association (NYHA) functional class, left ventricular ejection fraction, presence of pulmonary hypertension, and serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) values. We used receiver operating characteristic (ROC) curve to calculate the area under the curve (AUC) of Ea for predicting event-free survival in patients with HF. Results: The median age was 51 years, and 206 (72.5%) patients were male. Ea and pulmonary vascular resistance (PVR) were significantly correlated (r=0.698, P<0.001). The correlation between Ea and pulmonary arterial elastance (PAC) were even more significant (r=-0.888, P<0.001). Compared with Ea<0.555 group, Ea≥0.555 group presented with higher serum NT-proBNP values (4 443 (1 792, 8 554) ng/L vs. 1 721 (480, 4 528)ng/L,P<0.001), higher PVR (3.4 (2.5, 4.7) Wood vs. 1.4 (0.9, 2.2) Wood, P<0.001), lower cardiac output (3.0 (2.3, 3.9) L/min vs. 4.3 (3.8, 4.9) L/min, P<0.001), and lower PAC (1.6 (1.3, 2.0) ml/mmHg vs. 4.0 (3.0, 6.0) ml/mmHg, P<0.001). The median follow-up time was 392 (166, 811) days. The Kaplan-Meier survival curve demonstrated a lower event-free survival rate in the Ea≥0.555 group compared to the Ea<0.555 group (Plog-rank<0.001). After multivariate adjustment, Ea (HR=1.734, P<0.001) remained significantly associated with the primary outcome. Subgroup analysis indicated that Ea was associated with the primary outcome across all subgroups. The AUC was 0.724 (P<0.001) for Ea to predict event-free survival calculated from ROC analysis. Conclusions: Ea is closely related to parameters reflective of right ventricular afterload. Increased Ea is an independent predictor of adverse outcomes in patients with HF.

Abstract
Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that certain of the Hoechst staining data shown in Fig. 4E were strikingly similar to data appearing in different form in another article by different authors at a different research institute; moreover, an unexpectedly high degree of similarity was noted with the data featured in a couple of different data panels showing the results of apoptosis experiments in Fig. 4D. Owing to the fact that the contentious data in the above article had already been published prior to its submission to Molecular Medicine Reports, the Editor has decided that this paper should be retracted from the Journal. The authors were asked for an explanation to account for these concerns, but the Editorial Office did not receive a reply. The Editor apologizes to the readership for any inconvenience caused.

Abstract
To explore characteristics of outpatients in a single cardio-oncology clinic, patients visiting cardio-oncology clinic of Fuwai Hospital CAMS&PUMC (Beijing, China) from January 2020 to December 2021 were analyzed retrospectively. In total, 330 patients were included, the median age (Q1, Q3) was 58(46, 66) years, and there were 192 females (58.2%). The purposes for visit included an evaluation and treatment of cardiovascular adverse reactions (n=247, 74.8%), pre-antitumor therapy assessment (n=51, 15.5%), and management of primary or metastatic cardiac tumors (n=32, 9.7%). For patients with cardiovascular adverse reactions, the most common tumor type was breast cancer (n=88, 29.5%), followed by gastrointestinal cancer (n=70, 23.5%), and hematological cancers (n=62, 20.8%). Among them, 236 cases (95.5%) had received antitumor drugs in the past; 38 cases (15.4%) had a history of chest radiotherapy; some cases were complicated with hypertension (n=69, 23.2%) and/or hyperlipidemia (n=69, 23.2%); 42 cases (14.1%) had a history of coronary heart disease; and 16 cases (5.4%) were complicated with atrial fibrillation or flutter. Among 32 patients with cardiac tumors, 11 cases (34.4%) had primary malignant tumors; 6 cases (18.8%) had benign tumors; 2 cases (6.3%) had metastatic tumors; and 13 (40.6%) had unknown pathological types. This study explores the epidemiology of cardio-oncology in China and provides clinical insights for the future development of cardio-oncology. In the future, it is still necessary to study the benefits of cardio-oncology clinics and develop standardized indicators to evaluate their benefits.

Abstract
Objective: To investigate the effect of free triiodothyronine/free thyroxine (FT3/FT4) ratio on the prognosis of patients with heart failure (HF). Methods: A total of 3 527 patients hospitalized in the Heart Failure Center of Fuwai Hospital from March 2009 to June 2018 were analyzed in our study. Patients were divided into two groups according to median of FT3/FT4 ratio: low FT3/FT4 group (n=1 764, FT3/FT4<2.15) and high FT3/FT4 group (n=1 763, FT3/FT4≥2.15). The primary endpoint was defined as a composite endpoint of all-cause death or heart transplantation or implantation of a left ventricular assist device. The baseline characteristics of patients with different FT3/FT4 ratio groups were compared, and a multivariate Cox proportional hazard regression model was used to analyze the relationship between FT3/FT4 ratio and the prognosis of hospitalized patients with HF. Results: The age of the total population was (56.8±16.0) years, and 2 544 cases (72.1%) were males. The median follow-up time was 2.79 (1.00, 5.03) years, and a total of 1 542 end-point events were recorded at the final follow-up. The mean ages of patients in the low FT3/FT4 group and high FT3/FT4 group were (58.8±16.5) and (54.8±15.2) years (P<0.001), respectively; and the cumulative survival rates were 38.4% and 61.9%, respectively (P<0.001). FT3 (HR=0.72, 95%CI: 0.63-0.84, P<0.001), FT3/FT4 (HR=0.76, 95%CI: 0.65-0.87, P<0.001) was associated with all-cause death, heart transplantation, or LVAD implantation in patients with heart failure. HR values (95%CI) of FT3/FT4 ratio predicting the risk of composite endpoint in the subgroup of left ventricular ejection fraction (LVEF)<40%, 40% to 49%, and≥50% were 0.91 (0.77-1.08), 0.83 (0.50-1.39), and 0.65 (0.50-0.85), respectively (P interaction=0.045). Conclusions: Low FT3 and low FT3/FT4 are important correlative factors for poor prognosis in hospitalized HF patients, especially in patients with LVEF≥50%.

Abstract
BACKGROUND Gastrointestinal stromal tumor (GIST) is a common neoplasm with high rates of recurrence and metastasis, and its therapeutic efficacy is still not ideal. There is an unmet need to find new molecular therapeutic targets for GIST. TATA-box-binding protein-associated factor 15 (TAF15) contributes to the progress of various tumors, while the role and molecular mechanism of TAF15 in GIST progression are still unknown.
AIM To explore new molecular therapeutic targets for GIST and understand the biological role and underlying mechanisms of TAF15 in GIST progression.
METHODS Proteomic analysis was performed to explore the differentially expressed proteins in GIST. Western blotting and immunohistochemical analysis were used to verify the expression level of TAF15 in GIST tissues and cell lines. Cell counting kit-8, colony formation, wound-healing and transwell assay were executed to detect the ability of TAF15 on cell proliferation, migration and invasion. A xenograft mouse model was applied to explore the role of TAF15 in the progression of GIST. Western blotting was used to detect the phosphorylation level and total level of RAF1, MEK and ERK1/2.
RESULTS A total of 1669 proteins were identified as differentially expressed proteins with 762 upregulated and 907 downregulated in GIST. TAF15 was selected for the further study because of its important role in cell proliferation and migration. TAF15 was significantly over expressed in GIST tissues and cell lines. Overexpression of TAF15 was associated with larger tumor size and higher risk stage of GIST. TAF15 knockdown significantly inhibited the cell proliferation and migration of GIST in vitro and suppressed tumor growth in vivo. Moreover, the inhibition of TAF15 expression significantly decreased the phosphorylation level of RAF1, MEK and ERK1/2 in GIST cells and xenograft tissues, while the total RAF1, MEK and ERK1/2 had no significant change.
CONCLUSION TAF15 is over expressed in GIST tissues and cell lines. Overexpression of TAF15 was associated with a poor prognosis of GIST patients. TAF15 promotes cell proliferation and migration in GIST via the activation of the RAF1/MEK/ERK signaling pathway. Thus, TAF15 is expected to be a novel latent molecular biomarker or therapeutic target of GIST.

Abstract
Objective: To investigate the association between triiodothyronine (T3) and inflammatory factors, and its potential effect on long-term outcomes in hospitalized patients with heart failure (HF). Methods: A total of 2 475 patients with HF admitted in Heart Failure Care Unit were consecutively enrolled in this retrospective cohort study from December 2006 to June 2018. Patients were divided into low T3 syndrome group (n=610, 24.6%) and normal thyroid function group (n=1 865, 75.4%). The median follow-up time was 2.9 (1.0, 5.0) years. A total of 1 048 all-cause deaths were recorded at the final follow-up. The effects of free T3 (FT3) and high-sensitivity C-reactive protein (hsCRP) on the risk of all-cause death were evaluated by Cox regression analysis and Kaplan-Meier analysis. Results: The age of the total population was 19-95 (57±16) years, 1 823 cases (73.7%) were male. Compared to those with normal thyroid function, albumin [(36.5±5.4) vs. (40.7±4.7) g/L], hemoglobin [(129.4±25.1) vs. (140.6±20.6) g/L], total cholesterol [3.6 (3.0, 4.4) vs. 4.2 (3.5, 4.9) mmol/L] (all P<0.001) were lower, Whereas age [(60.5±16.0) vs. (55.2±15.4) years], creatinine [105.0 (83.6, 137.0) vs. 87.8 (75.6, 106.3) mmol/L], log N-terminal B-type natriuretic peptide [(8.2±1.3) vs. (7.2±1.4) ng/L] were higher in LT3S patients (all P<0.001). In Kaplan-Meier survival analysis, patients with lower FT3 and higher hsCRP had significantly lower cumulative survival (P<0.001), lower FT3 combined with higher hsCRP subgroup had the highest risk of all-cause death (Ptrend<0.001). In multivariate Cox regression analysis, LT3S was an independent predictor of all-cause mortality (HR=1.40, 95%CI 1.16-1.69, P<0.001). Conclusion: LT3S is an independent predictor of poor prognosis in patients with heart failure. FT3 combined with hsCRP improve the predictive value of all-cause death in hospitalized patients with heart failure.

Abstract
OBJECTIVE Aside from the severity, surgical interventions for the treatment of neurological dysfunctions remain controversial. This study aimed to find factors predicting the benefits of tethered cord syndrome (TCS) surgery. PATIENTS AND METHODS 80 children with TCS were included and followed up for pre- and post-operative factors along with neurophysiological analysis. Outcomes were assessed by univariate and multivariate analysis. RESULTS Surgical treatment not only improved preoperative signs and symptoms in 79% of TCS patients but it showed to be an efficient procedure for the occurrence of future neurological defects. Univariate analysis also revealed that surgical intervention in TCS children (age <1 year) can modulate filar lipoma location and cutaneous abnormalities three months after surgery. Neurophysiological assessment revealed only 5.0% of surgical complications in TCS patients. Two patients had cerebrospinal fluid leakage, and two cases of CNS infection were detected. CONCLUSIONS Surgical intervention is highly recommended for the prevention of neurological deficits in children with TCS. Electrophysiological monitoring revealed rare complications following the surgery.

Abstract
Background and Objective Ectopic embolism caused by cyanoacrylate glue for the treatment of gastric varices with obvious spontaneous portosystemic shunts is a serious complication of endoscopic therapy. This study was performed to investigate the safety and therapeutic effect of EUS-guided coil placement and cyanoacrylate glue injection for gastric varices with obvious spontaneous portosystemic shunts. Materials and Methods Six patients with gastric variceal bleeding and obvious spontaneous portosystemic shunts were included in this study. We evaluated the success rate of variceal occlusion after intraoperative embolization, the postoperative rebleeding rate at 48 h and 2 weeks posttreatment, and the incidence of ectopic embolism and other adverse events. Gastroscopy and computed tomography portal venography (CTPV) were performed 7 months later. Results All patients underwent successful coil placement and cyanoacrylate glue injection under EUS guidance. The blood flow was confirmed by Doppler examination, the target vessels were successfully blocked, and no rebleeding had occurred at 48 h or 2 weeks after endoscopic treatment. Gastroscopy was repeated 7 months after endoscopic treatment, revealing local ulcer formation. CTPV was also repeated 7 months after endoscopic treatment, showing that the coils were present in the target vessels with no displacement, the portosystemic shunt vessels were occluded, and no ectopic embolization had occurred. Conclusion The coil placement combined with cyanoacrylate glue embolism is a safe and effective method for patients with gastric variceal bleeding and obvious spontaneous portosystemic shunts.

Abstract
This study aimed to investigate the expression and cellular function of the centromeric family of proteins (CENPs), especially centromere protein I (CENP-I), in gastric cancer (GC) and identified its clinical significance and cellular functions. CENP-I expression in GC was studied by cDNA microarray, quantitative real-time PCR (qRT-PCR), and immunohistochemistry (IHC), and using datasets from The Cancer Genome Atlas (TCGA), UALCAN, and Gene Expression Omnibus (GEO) databases. Microarray and bioinformatic analyses identified upregulated CENP-A/E/F/H/I/K/P/W and HJURP in stomach adenocarcinoma (STAD), but not in signet ring cell carcinoma (SRCC). Significantly higher CENP-I mRNA expression was also confirmed in 40 pairs of GC tissues than in paired normal gastric tissues by qRT-PCR (P<.001). IHC showed that elevated CENP-I expression was associated with higher tumor stage, lymph node invasion, increased HER2-positive rate (36.7% vs 10.0%), and intestinal Lauren classification in 69 GC samples compared to paired paracancerous normal tissues. The survival of the high-CENP-I group members was poor compared with that of the low-CENP-I group (P = .0011). Cox univariate regression analysis identified tumor size (P = .008), HER2 status (P = .027), and CENP-I expression (P = .049) were independent prognostic factors of GC. The cellular function of CENP-I was studied in MKN45 and MKN28 GC cell lines in vitro. Cell proliferation, migration, and apoptosis were determined using CCK-8, transwell assay, TUNEL assay, and flow cytometry. Our results showed that CENP-I promoted GC cell proliferation, inhibited apoptosis, facilitated cell migration, and induced epithelial–mesenchymal transition (EMT), possibly by activating the AKT pathway. CENP-I expression was correlated with genetic signatures of the proliferative subtype of GC, characterized by intestinal Lauren classification, HER2 amplification, and TP53 mutation. In conclusion, this study revealed an elevated CENP-I expression in GC, which was associated with malignant features and poor prognosis of GC patients, and identified its function in modulating cell proliferation, apoptosis, and migration.

Abstract
Objective: To investigate the clinical characteristics of patients with hypertrophic cardiomyopathy (HCM) and restrictive cardiomyopathy (RCM) complicating with intracardiac thrombosis. Methods: This is a retrospective observational study. Consecutive patients diagnosed with HCM or RCM and complicated with intracardiac thrombosis (including left and right atrium or ventricular thrombosis), who were admitted to the Heart Failure Care Unit of Fuwai Hospital, Chinese Academy of Medical Sciences, from September 2008 to September 2018, were enrolled in this study. Patients with myocardial infarction were excluded. The general clinical data of the enrolled patients, including demographic data, major complications, laboratory indicators, echocardiographic indicators, drug application and distribution of intracardiac thrombosis, were collected from electronic medical record system and analyzed. Results: A total of 98 patients were enrolled in this study, including 52 patients (53.1%) with HCM and 46 patients (46.9%) with RCM. The most common comorbidity was atrial fibrillation/flutter: 40 patients (76.9%) in HCM group and 36 patients (78.3%) in RCM group. Majority of patients received oral anticoagulants treatment: 43 patients (82.7%) in HCM group and 35 patients (76.1%) in RCM group. Intracardiac thrombosis was mainly located in the left atrium in both HCM group (39 cases (75.0%)) and RCM group (32 cases (69.6%)). Thrombosis was found in ≥ 2 chambers in 7 patients (7.1%). Rate of left atrial thrombosis was the highest (81.6% (62/76)) in HCM and RCM patients complicating with atrial fibrillation/flutter. Intra-aneurysmal thrombosis occurred in 4 out of 5 patients complicated with apical left ventricular aneurysm. The rate of left ventricular thrombosis in patients with left ventricular ejection fraction≥50% was 7.4% (4/54), which was significantly lower than that in patients with left ventricular ejection fraction<50% (34.5%(10/29)) (P<0.01). Conclusion: There are certain distribution characteristics of HCM and RCM patients with intracardiac thrombosis, and the left atrium is the most common site of thrombosis, more attention should be paid in HCM and RCM patients on the diagnosis and treatment of intracardiac thrombosis.

Abstract
Objective: To investigate the risk factors of peritoneal metastasis in primary appendiceal tumor. Methods: The clinic data of 71 patients with primary appendiceal tumor admitted in the Sixth Affiliated Hospital of Sun Yat-sen University between Dec 2012 and Jan 2019 were enrolled retrospectively. Multivariate logistic regression analysis were carried out to evaluate the risk factors of appendiceal tumor with peritoneal metastasis. Results: Of the 71 patients, 33 were peritoneal metastasis (peritoneal metastasis group) and 38 were non-peritoneal metastasis (no peritoneal metastasis group). Twenty-one patients in the peritoneal metastasis group had increased preoperative cancer embryo antigen (CEA), while 3 cases in the non-peritoneal metastasis group, with statistically significant difference (P<0.001). Sixteen cases in peritoneal metastasis group had increased preoperative carbohydrate antigen 199, while only 2 cases in the non-peritoneal metastasis group, the difference was statistically significant (P<0.001). The pathological type of 30 cases in the peritoneal metastasis group was adenocarcinoma (including mucus adenocarcinoma and colon adenocarcinoma), while 12 cases of adenocarcinoma in the non-peritoneal metastasis group, with statistically significant difference (P<0.001). Twelve cases in the peritoneal metastasis group had lymph node metastasis, while 3 cases in the non-peritoneal metastasis group, the difference is statistically significant (P=0.003). Preoperative CEA elevation and pathological type is adenocarinoma were independent risk factors for peritoneal metastasis of appendiceal cancer (P<0.05). Conclusions: The propensity of peritoneal metastasis in primary appendiceal tumor is high and the outcome is poor. Patients with increased preoperative CEA, adenocarcinoma histopathology are more inclined to have peritoneal metastasis.

Abstract
Objective: To investigate the clinical type and gene mutations, clinical manifestations, laboratory tests, diagnosis, and fibrinogen replacement therapy of congenital fibrinogen disorders. Methods: Clinical data of 146 patients with congenital fibrinogen disorders diagnosed from April 2000 to November 2020 were retrospectively analyzed. Results: Among the 146 patients, 61 (41.8%) men and 85 (58.2%) women had a median age of 33.5 years at the time of consultation. 34 patients (34.7%) were found to suffer from the disease due to bleeding symptoms, 33 patients (33.7%) due to preoperative examination. 55 patients (56.1%) had at least one bleeding symptom, and 42 patients (42.9%) had no bleeding symptoms. There is a negative correlation between fibrinogen activity concentration and bleeding ISTH-BAT score (rs=-0.412, P=0.001) . A total of 34 gene mutations were detected in 56 patients, of which 84.1% were missense mutations, and 16 new mutations were found. FGA Exon2 and FGG Exon8 mutations accounted for 71.4% of all mutation sites. Patients with afibrinogenemia were younger, with a median age of 2 (1-12) years, an ISTH-BAT score of 4, and patients with dysfibrinogenemia had significantly longer thrombin time (TT) , with a median of 28.5 (19.2-36.6) s. The 1 hour in vivo recovery (IVR) after fibrinogen infusion was (127.19±44.03) %, and the 24 hour IVR was (101.78±43.98) %. In addition to the obvious increase in the concentration of fibrinogen activity, the TT and the prothrombin time (PT) both decreased significantly, and the TT decreased more significantly, with an average decrease of 15.2% compared to the baseline after 24 hours of infusion. Conclusion: Most patients with congenital fibrinogen disorders have mild or no bleeding symptoms. Patients with afibrinogenemia have more severe symptoms. There is a negative correlation between the fibrinogen and the degree of bleeding. Genetic testing is helpful for the diagnosis of disease classification. FIB∶C/FIB∶Ag<0.7 can be used as a basis for clinical diagnosis. The TT can be used as the basis for the diagnosis of dysfibrinogenemia and the effectiveness of fibrinogen infusion.

Abstract
Objective: To explore the possibility of using artificial intelligence (AI) technology based on convolutional neural network (CNN) to assist the clinical diagnosis of laryngeal squamous cell carcinoma (LSCC) through deep learning algorithm. Methods: A deep CNN was developed and applied in narrow band imaging (NBI) endoscopy of 4 799 patients with laryngeal lesions, including 3 168 males and 1 631 females, aged from 21 to 87 years, from 2015 to 2017 in Beijing Tongren Hospital, Capital Medical University. A simple randomization method was used to select the laryngeal NBI images of 2 427 patients (1 388 benign lesions and 1 039 LSCC lesions) for the training and correction the CNN model. The remaining laryngeal NBI images of 2 372 patients (including 1 276 benign lesions and 1 096 LSCC lesions) were used as validation data set to compare performance between CNN and otolaryngologists. SPSS 21.0 software was used for Chi-square test to calculate the accuracy, sensitivity and specificity of AI and otolaryngologists. The area under the curve (AUC) of receiver operating curve (ROC) was used to evaluate the diagnostic ability of the algorithm for NBI images. Results: The accuracy, sensitivity and specificity for NBI predictions were respectively 90.91% (AUC=0.96), 90.12% and 91.53%, which were equivalent to those for otolaryngologists' predictions (accuracy, sensitivity and specificity were (91.93±3.20)%, (91.33±3.25)% and (93.02±2.59)%, t values were 0.64, 0.75 and 1.17, and P values were 0.32, 0.28 and 0.21, respectively). The diagnostic efficiency of CNN was significantly higher than that of otolaryngologists (0.01 vs. 5.50, t =9.15, P<0.001). Conclusion: AI based on deep CNN is effective for using in the laryngeal NBI image diagnosis, showing a good application prospect in the diagnosis of LSCC.

Abstract
BACKGROUND Accurate and robust pathological image analysis for colorectal cancer (CRC) diagnosis is time-consuming and knowledge-intensive, but is essential for CRC patients' treatment. The current heavy workload of pathologists in clinics/hospitals may easily lead to unconscious misdiagnosis of CRC based on daily image analyses. METHODS Based on a state-of-the-art transfer-learned deep convolutional neural network in artificial intelligence (AI), we proposed a novel patch aggregation strategy for clinic CRC diagnosis using weakly labeled pathological whole-slide image (WSI) patches. This approach was trained and validated using an unprecedented and enormously large number of 170,099 patches, > 14,680 WSIs, from > 9631 subjects that covered diverse and representative clinical cases from multi-independent-sources across China, the USA, and Germany. RESULTS Our innovative AI tool consistently and nearly perfectly agreed with (average Kappa statistic 0.896) and even often better than most of the experienced expert pathologists when tested in diagnosing CRC WSIs from multicenters. The average area under the receiver operating characteristics curve (AUC) of AI was greater than that of the pathologists (0.988 vs 0.970) and achieved the best performance among the application of other AI methods to CRC diagnosis. Our AI-generated heatmap highlights the image regions of cancer tissue/cells. CONCLUSIONS This first-ever generalizable AI system can handle large amounts of WSIs consistently and robustly without potential bias due to fatigue commonly experienced by clinical pathologists. It will drastically alleviate the heavy clinical burden of daily pathology diagnosis and improve the treatment for CRC patients. This tool is generalizable to other cancer diagnosis based on image recognition.

Abstract
Objective: To analyze the difference among expression of aqueous humor proteins in acute primary angle-closure glaucoma (APACG). Methods: Case-control study. The patients with APACG combined cataract (APACG with cataract group) and patients with cataract (cataract group), who had undertaken surgical treatment at the Tianjin Medical University Eye Hospital from October 2016 to June2017 were collected. Upon receipt of patient's consent, 50 μl of aqueous humor were collected with 1 ml syringe and No.1 needle through the surgical access during the surgery, and then injected into a sterile collection tube to be stored at -80 ℃. Those proteins extracted from aqueous humor were analyzed by quantitative proteomic mass spectrometry. The differential significance test was performed by Maxquant significances A approach. The differential proteins of the two groups were screened and determined with the conditions of P<0.05 and difference multiple>2. The functions and signal pathway of differential proteins in aqueous humor were annotated in biological big data, on the basis gene ontology (GO) and the Kyoto gene and genomic encyclopedia (KEGG) analyses. Results: There were 3 males and 7 females with an average age of (68±6) years in the APACG group. The cataract group included 2 males and 8 females with an average age of (71±8) years. There were no statistical differences in gender ratio and age between the two groups (both P>0.05). A total of 91 differential proteins were detected in this experiment, including 50 up-regulated proteins (annexinA1, vimentin, S100 calcium binding protein A8, interleukin 6, C reactive protein, laminin β2, etc.) and 41 down-regulated (keratin 85, γ-crystallin D, syntaxin-binding protein 5, semaphoring 4B, matrilin 2, cathepsin O, cadherin 4, semaphoring 3B, platelet-derived growth factor D, transforming growth factor β, etc.). On one hand, the functions of differential proteins involved in many aspects. AnnexinA1, CD163, S100 calcium-binding protein A8, C reactive protein, interleukin 6 are involved in the inflammatory reaction, cadherin 4 and laminin β2 regulate cell adhesion, matrilin 2, vimentin and laminin β2 participate in tissue fibrosis; on the other hand, KEGG analysis showed that the differential proteins participate diverse signaling pathways such as phosphatidylinositol-3-kinase-protein kinase B signaling pathway, transformation growth factor β signaling pathway, mitogen activated protein kinase signaling pathway, Toll-like receptor signaling pathway, the nuclear factor κ-light chain enhancer of the activated B cells signaling pathway, focal adhension and extracellular matrix receptor interaction pathway and so on. Conclusions: The expression of annexin A1 is significantly up-regulated in the aqueous humor in APACG, while some other factors such as transformation growth factor β, cadherin-4, and matrilin 2 are down-regulated. The change of proteins in aqueous humor is related with the outbreak of APACG. (Chin J Ophthalmol, 2019, 55: 687-694).

Abstract
Objective: This study was to observe the effect of SMP-30 on ultraviolet B (UVB)-induced apoptosis of human lens epithelial cells(HLE-B3) in vitro. Methods: Experimental study. The SMP-30 cDNA was amplified by PCR and inserted into the pRFP-N1 expressing vector which had been double digested by XhoI/HindIII. HLE-B3 cells were cultured and divided into three groups: normal group, pRFP-N1 vector plasmid group and pRFP-N1-SMP-30 plasmid group (SMP-30). Then cells were exposed to UVB and the survival rate of cells was detected by MTT assay. The effects of SMP-30 on UVB-induced HLE-B3 apoptosis were measured by the Cell Death Detection ELISA kit. Meanwhile, the influence of SMP-30 on UVB-induced apoptosis-relative protein expression in HLE-B3 cells was tested by Western blots. Moreover, 2', 7'-Dichlorofluorescin diacetate staining was performed to monitor the protective effects of SMP-30 on UVB-induced HLE-B3 reactive oxygen species(ROS). One-way analysis of variance combined with Dunnett's statistical method were performed to analyze the data. Results: The full length of PSF cDNA fragment was correctly inserted into the pRFP-N1 vector, which was confirmed by DNA sequencing. The SMP-30 fragment was inserted to the plasmid pRFP-N1 correctly, which was also confirmed by DNA sequencing. The PRFP-N1-SMP-30 plasmid was transfected into HLE-B3 successfully. SMP-30 expression was up-regulated in the transfection group, compared with the control group. Data showed that the survival rate of HLE-B3 after the pRFP-N1-SMP-30 plasmid transfection was 0.90±0.14, while the apoptosis rate was 0.43±0.06 and the ROS production was 0.52±0.02, showing significant difference in comparison with the vector plasmid group and the normal group(t=5.830, 9.934, 12.19, P<0.05). In the meantime, SMP-30 overexpression down-regulated the levels of Bax and cleav-caspase-3, but up-regulated the Bcl-2 and Pro-caspase-3 expression levels under UVB irradiation. Conclusion: SMP-30 overexpression plays a protective role in UVB-induced apoptosis via regulating the expression of apoptosis-related proteins and inhibiting the production of ROS in HLE-B3 cells.

Abstract
SUMMARY OBJECTIVE: This study retrospectively reviewed 46 cases of gastric gastrointestinal stromal tumors treated by endoluminal endoscopic full-thickness resection (EFR) microsurgery in our gastrointestinal endoscopy center. We aimed to evaluate the EFR for the treatment of gastric gastrointestinal stromal tumors originating from the muscularis propria. METHODS: A total of 46 patients with gastric gastrointestinal stromal tumors originated from the muscularis propria layer from January 2012 to June 2015 were treated with EFR. The patients were followed up with gastroscope and computed tomography (CT) for evaluation of therapeutic effect and safety. RESULTS: EFR was successfully accomplished to remove all tumors in 46 patients. The mean procedure time was 82.5±39.8min (56-188min). Except in 3 leiomyomas, pathological examination confirmed gastrointestinal stromal tumor (GIST) in 43 cases. None of the patients had occurred bleeding, peritonitis and other complications after EFR. Thereafter, all patients were followed up with gastro-scope after 1, 6,12 months. CONCLUSIONS: EFR is effective and safe for patients with gastric gastrointestinal stromal tumors originated from muscularis propria layer and has the advantage of less invasive treatment and higher tumor resection rate. It should be considered for further application.

Abstract
Background: The diagnosis and treatment of small-bowel diseases is clinically difficult. The purpose of this study was to evaluate the diagnostic and therapeutic value of double-balloon enteroscopy in small-bowel diseases. Methods: The history and outcomes of 2806 patients who underwent double-balloon enteroscopy from July 2004 to April 2017 were reviewed, which included 562 patients with obscure digestive tract bleeding, 457 patients with obscure diarrhea, 930 patients with obscure abdominal pain, 795 patients with obscure weight loss, and 62 patients with obscure intestinal obstruction. Examinations were performed through the mouth and/or anus according to the clinical symptoms and abdominal images. If a lesion was not detected through one direction, examination through the other direction was performed as necessary. Eighty-four patients with small-bowel polyps, 26 with intestinal obstruction caused by enterolith, and 18 with bleeding from Dieulafoy's lesions in the small intestine were treated endoscopically. Results: A total of 2806 patients underwent double-balloon enteroscopy, and no serious complications occurred. An endoscopic approach through both the mouth and anus was used in 212 patients. Lesions were detected in 1696 patients, with a detection rate of 60.4%; the rates for obscure digestive tract bleeding, diarrhea, abdominal pain, weight loss, and intestinal obstruction were 85.9% (483/562), 73.5% (336/457), 48.2% (448/930), 49.1% (390/795), and 62.9% (39/62), respectively. For patients with small-bowel polyps who underwent endoscopic therapy, no complications such as digestive tract bleeding and perforation occurred. Intestinal obstruction with enteroliths was relieved with endoscopic lithotripsy. Among the 18 patients with bleeding from small-bowel Dieulafoy's lesions, 14 patients were controlled with endoscopic hemostasis. Conclusion: Double-balloon enteroscopy is useful for diagnosing and treating some small-bowel disease.

Abstract
Objective: To study the clinicopathologic characteristics, immunophenotype, pathologic diagnosis and differential diagnosis of myxoid adrenocortical adenomas. Methods: The clinical data, histological features and immunohistochemical results of 4 cases of myxoid adrenocortical adenomas were analyzed, which were collected from January 2014 to December 2016 at Guangdong General Hospital, with review of literature. Results: Four cases of myxoid adrenocortical adenomas were presented. The patients ages ranged from 26 to 45 years (mean =35 years). Microscopically, it showed a typical morphology, characterized by small-sized tumor cell cords or pseudo-glands embedded in an abundant extracellular myxoid matrix. Immunohistochemical staining showed tumor cells were strongly positive for Melan A, vimentin and focally for α-inhibin, one case showed strong and diffuse positivity for CAM5.2, and two cases showed diffuse positivity for synaptophysin, while negative for CgA, S-100 protein, epithelial antigen, CK7, CK20 and CKpan. Conclusions: Myxoid adrenocortical adenomas are extremely rare, which may cause confusion with metastatic well-differentiated neuroendocrine tumours, sex cord-stromal tumoursor metanephric adenoma. Recognition of this entity would be beneficial for pathologists to avoid misdiagnosis, and unnecessary treatment.

Abstract
As one of the most aggressive types of tumor, pancreatic cancer is a principal cause of tumor‑associated mortality. Negative associations between microRNA‑29 (miR‑29) and DNA methyltransferases (DNMT) 3a and 3b have been demonstrated to be associated with the carcinogenesis of a number of types of cancer; however, this has not been completely elucidated in pancreatic cancer. In the present study, pancreatic cancer tissues (n=15) and corresponding paracancerous tissues (n=15) were obtained and the results of reverse transcription‑quantitative polymerase chain reaction analysis indicated decreased expression of miR‑29b and enhanced mRNA expression of DNMT3b in pancreatic cancer tissues, compared with the corresponding paracancerous tissues. Increased protein expression of DNMT3b was demonstrated by western blotting and immunohistochemistry. In addition, the negative association between miR‑29b and DNMT3b was noted in pancreatic cancer tissues, and luciferase reporter assays confirmed that miR‑29b was able to directly target DNMT3b in vitro. Notably, miR‑29b overexpression was able to decrease cell viability and to promote the apoptosis by targeting DNMT3b, and the knockdown of DNMT3b exhibited consistent results in vitro and in vivo. The results of the present study suggested that miR‑29b, as a tumor suppressor, may be a novel target for the development of treatments for pancreatic cancer.

Abstract
Thromboembolism (TE) is an extraintestinal manifestation (EIM) of inflammatory bowel disease (IBD). According to previous pathological reports, the incidence of IBD complicated with TE is as high as 41%. However, this EIM is often overlooked. This review summarizes the results of the relevant clinical studies to date, analyzes the potential prothrombotic risk of IBD drug therapy, and discusses the current status on the treatment and prevention of TE, with an aim to provide a comprehensive reference for clinical work.

Abstract
BACKGROUND Healthcare-associated infection (HCAI) represents a major problem for patient safety worldwide. AIM To demonstrate the prevalence, causative agents, and risk factors for HCAI in Chinese hospitals. METHODS A one-day point-prevalence survey was conducted in 52 Chinese hospitals between October 2014 and March 2015. A web-based software system was developed for data entry and management. FINDINGS Among 53,939 patients surveyed, the prevalence of patients with at least one HCAI was 3.7%. Of 2182 HCAI episodes, the most frequently occurring types were lower respiratory tract infections (47.2%), followed by urinary tract infection (12.3%), upper respiratory tract infection (11.0%), and surgical site infection (6.2%). The prevalence of patients with at least one HCAI in critical care units was highest (17.1%). Device-associated infections, including ventilator-associated pneumonia, catheter-associated urinary tract infection, and central catheter-associated bloodstream infection, accounted for only 7.9% of all HCAIs. The most frequently isolated micro-organisms were Pseudomonas aeruginosa [206 infections (9.4%)], Acinetobacter baumannii [172 infections (7.9%)], Klebsiella pneumoniae [160 infections (7.3%)], and Escherichia coli [145 infections (6.6%)]. Of the survey patients (18,206/53,939), 33.8% were receiving at least one antimicrobial agent at the time of the survey. Risk factors for HCAI included older age (≥80 years), male gender, days of hospital admission, admission into a critical care unit, and device utilization. CONCLUSION Our study suggests that the overall prevalence of HCAI in surveyed Chinese hospitals was lower than that reported from most European countries and the USA. More attention should be given to the surveillance and prevention of non-device-associated HCAI in China.

Abstract
BACKGROUND Gastric stromal tumors arising from the muscularis propria are located in deeper layers. Endoscopic resection may be contraindicated due to the possibility of perforation. These tumors are therefore usually removed by surgical or laparoscopic procedures. This study evaluated the curative effects, safety and feasibility of endoscopic full-thickness resection (EFR) of gastric stromal tumors originating from the muscularis propria. METHODS This study enrolled 92 patients with gastric stromal tumors >2.5 cm originating from the muscularis propria. Fifty patients underwent EFR, and 42 underwent laparoscopic intragastric surgery. Operation time, complete resection rate, length of hospital stay, incidence of complications, and recurrence rates were compared in these two groups. RESULTS EFR resulted in complete resection of all 50 gastric stromal tumors, with a mean procedure time of 85 ± 20 min, a mean hospitalization time of 7.0 ± 1.5 days and no complications. Laparoscopic intragastric surgery also resulted in a 100% complete resection rate, with a mean operation time of 88 ± 12 min and a mean hospitalization period of 7.5 ± 1.6 days. The two groups did not differ significantly in operation time, complete resection rates, hospital stay or incidence of complications (P > 0.05). No patient in either group experienced tumor recurrence. CONCLUSIONS EFR technique is effective and safe for the resection of gastric stromal tumors arising from the muscularis propria.

Abstract
The goal of present study was to investigate the relationship between polymorphisms of TGF-β1 and familial aggregation of liver cancer in Guangxi Zhuang, Han, and Yao populations. We conducted a population-based case-control family study of liver cancer in Guanxi, China. A total of 214 individuals from 37 case families were surveyed for polymorphisms in TGF-β1. We genotyped six functional TGF-β1 polymorphisms: rs1800469, rs2241715, rs2241716, rs11466345, rs8105161, and rs747857. Levels of TGF-β1, hepatitis B surface antigen, and anti-hepatitis C virus in all serum samples were detected using the enzyme-linked immunoassay method, and presence of hepatitis B virus (HBV) DNA was determined using polymerase chain reaction amplification. A standardized questionnaire was used to collect information from subjects, including alcohol consumption, smoking, eating, and water drinking habits. The results were compared with those from 214 control individuals. The results showed that the TGF-β1 genotypes rs1800469, rs2241715, rs2241715, and rs8105161 were more frequent in patients than in controls. The risk factors for familial aggregation of liver cancer in Guangxi were determined, from high to low, to be: drinking sugared beverages > alcohol consumption > HBV DNA-positive > rs1800469 TT homozygous genotype > rs2241715 TT homozygous genotype. The results suggested that TGF-β1 rs1800469 TT and rs2241715 TT homozygote genotypes represent the genetic factors underlying familial clustering of liver cancer in Guangxi, and that drinking water use, alcohol consumption, and testing positive for HBV DNA are the main environmental factors contributing to familial aggregation of liver cancer in Guangxi.

Abstract
AIM: To investigate the effects of activated rat hepatic stellate cells (HSCs) on rat Th1/Th2 profile in vitro.
METHODS: Growth and survival of activated HSCs and CD4+ T lymphocytes cultured alone or together was assessed after 24 or 48 h. CD4+ T lymphocytes were then cultured with or without activated HSCs for 24 or 48 h and the proportion of Th1 [interferon (IFN)-γ+] and Th2 [interleukin (IL)-4+] cells was assessed by flow cytometry. Th1 and Th2 cell apoptosis was assessed after 24 h of co-culture using a caspase-3 staining procedure. Differentiation rates of Th1 and Th2 cells from CD4+ T lymphocytes that were positive for CD25 but did not express IFN-γ or IL-4 were also assessed after 48 h of co-culture with activated HSCs. Galectin-9 expression in HSCs was determined by immunofluorescence and Western blotting. ELISA was performed to assess galectin-9 secretion from activated HSCs.
RESULTS: Co-culture of CD4+ T lymphocytes with activated rat HSCs for 48 h significantly reduced the proportion of Th1 cells compared to culture-alone conditions (-1.73% ± 0.71%; P < 0.05), whereas the proportion of Th2 cells was not altered; the Th1/Th2 ratio was significantly decreased (-0.44 ± 0.13; P < 0.05). In addition, the level of IFN-γ in Th1 cells was decreased (-65.71 ± 9.67; P < 0.01), whereas the level of IL-4 in Th2 cells was increased (82.79 ± 25.12; P < 0.05) by co-culturing, as measured by mean fluorescence intensity by flow cytometry. Apoptosis rates in Th1 (12.27% ± 0.99%; P < 0.01) and Th2 (1.71% ± 0.185%; P < 0.01) cells were increased 24 h after co-culturing with activated HSCs; the Th1 cell apoptosis rate was significantly higher than in Th2 cells (P < 0.01). Galectin-9 protein expression was significantly decreased in HSCs only 24 h after co-culturing (P < 0.05) but not after 48 h. Co-culture for 48 h significantly increased the differentiation of Th1 and Th2 cells; however, the increase in the proportion of Th2 cells was significantly higher than that of Th1 cells (1.85% ± 0.48%; P < 0.05).
CONCLUSION: Activated rat HSCs lower the Th1/Th2 profile, inhibiting the Th1 response and enhancing the Th2 response, and this may be a novel pathway for liver fibrogenesis.

Abstract
AIM The third ventricle is located deep in the brain and is adjacent to important neurovascular structures. This makes tumor resection in this region difficult and causes more postoperative complications than surgeries in other regions of the brain. The objective of this study was to investigate the feasibility and clinical effects of transcallosal-interforniceal approach for microsurgical removal of the third ventricle tumors. METHODS After preoperative evaluation, 23 patients with the third ventricle tumors were microsurgically operated using the transcallosal-interforniceal approach. RESULTS Of these 23 patients, 12 (52.2%) underwent total excision, 9 (39.1%) had subtotal resection, and the remaining 2 (8.7%) underwent partial excision. After surgery, the following complications were observed: diabetes insipidus (11 patients), hemorrhages of the upper digestive tract (2 patients), central fever (1 patient), and memory impairment (1 patient). No mortality in the perioperative period was reported. CONCLUSION The surgical procedure using the transcallosal-interforniceal approach is direct and provides good surgical field exposure and fewer post operational compilations. This approach should be considered as the method of choice for surgical removal of the third ventricle tumors.

Abstract
AIM: To evaluate the efficacy, safety and feasibility of endoscopic full-thickness resection (EFR) for the treatment of gastric submucosal tumors (SMTs) arising from the muscularis propria.
METHODS: A total of 35 gastric SMTs arising from the muscularis propria layer were resected by EFR between January 2010 and September 2013. EFR consists of five major steps: injecting normal saline into the submucosa; pre-cutting the mucosal and submucosal layers around the lesion; making a circumferential incision as deep as the muscularis propria around the lesion using endoscopic submucosal dissection and an incision into the serosal layer around the lesion with a Hook knife; a full-thickness resection of the tumor, including the serosal layer with a Hook or IT knife; and closing the gastric wall with metallic clips.
RESULTS: Of the 35 gastric SMTs, 14 were located at the fundus, and 21 at the corpus. EFR removed all of the SMTs successfully, and the complete resection rate was 100%. The mean operation time was 90 min (60-155 min), the mean hospitalization time was 6.0 d (4-10 d), and the mean tumor size was 2.8 cm (2.0-4.5 cm). Pathological examination confirmed the presence of gastric stromal tumors in 25 patients, leiomyomas in 7 and gastric autonomous nerve tumors in 2. No gastric bleeding, peritonitis or abdominal abscess occurred after EFR. Postoperative contrast roentgenography on the third day detected no contrast extravasation into the abdominal cavity. The mean follow-up period was 6 mo, with no lesion residue or recurrence noted.
CONCLUSION: EFR is efficacious, safe and minimally invasive for patients with gastric SMTs arising from the muscularis propria layer. This technique is able to resect deep gastric lesions while providing precise pathological information about the lesion. With the development of EFR, the indications of endoscopic resection might be extended.

Abstract
The small intestine is approximately 5-6 m long and occupies a large area in the abdominal cavity. These factors preclude the use of ordinary endoscopy and X-ray to thoroughly examine the small intestine for bleeding of vascular malformations. Thus, the diagnosis of intestinal bleeding is very difficult. A 47-year-old man presented at the hospital 5 mo ago with dark stool. Several angiomas were detected by oral approach enteroscopy, but no active bleeding was observed. Additionally, no lesions were detected by anal approach enteroscopy; however, gastrointestinal tract bleeding still occurred for an unknown reason. We performed an abdominal vascular enhanced computed tomography examination and detected ileal vascular malformations. Ileum angioma and vascular malformation were detected by a laparoscopic approach, and segmental resection was performed for both lesions, which were confirmed by pathological diagnosis. This report systemically emphasizes the imaging findings of small intestinal vascular malformation bleeding.

Abstract
AIM: To assess the effectiveness of endoscopic full-thickness resection (EFR) and laparoscopic surgery in the treatment of gastric stromal tumors arising from the muscularis propria.
METHODS: Out of 62 gastric stromal tumors arising from the muscularis propria, each > 1.5 cm in diameter, 32 were removed by EFR, and 30 were removed by laparoscopic surgery. The tumor expression of CD34, CD117, Dog-1, S-100, and SMA was assessed immunohistochemically. The operative time, complete resection rate, length of hospital stay, incidence of complications, and recurrence rate were compared between the two groups. Continuous data were compared using independent samples t-tests, and categorical data were compared using χ2 tests.
RESULTS: The 32 gastric stromal tumors treated by EFR and the 30 treated by laparoscopic surgery showed similar operative time [20-155 min (mean, 78.5 ± 30.1 min) vs 50-120 min (mean, 80.9 ± 46.7 min), P > 0.05], complete resection rate (100% vs 93.3%, P > 0.05), and length of hospital stay [4-10 d (mean, 5.9 ± 1.4 d) vs 4-19 d (mean, 8.9 ± 3.2 d), P >0.05]. None of the patients treated by EFR experienced complications, whereas two patients treated by laparoscopy required a conversion to laparotomy, and one patient had postoperative gastroparesis. No recurrences were observed in either group. Immunohistochemical staining showed that of the 62 gastric stromal tumors diagnosed by gastroscopy and endoscopic ultrasound, six were leiomyomas (SMA-positive), one was a schwannoglioma (S-100 positive), and the remaining 55 were stromal tumors.
CONCLUSION: Some gastric stromal tumors arising from the muscularis propria can be completely removed by EFR. EFR could likely replace surgical or laparoscopic procedures for the removal of gastric stromal tumors.

Abstract
We aimed to investigate the role of 4 single nucleotide polymorphisms of the xeroderma pigmentosum complementation group F (XPF) gene (rs3136038, rs1799798, rs1800067, and rs2276466) in glioma, and the roles of gene-gene interactions in the risk of developing this type of cancer. We collected samples from 225 glioma cases and 262 controls and genotyped the rs3136038, rs1799798, rs1800067, and rs2276466 polymorphisms using a 384-well plate format with the Sequenom MassARRAY platform. Individuals carrying the rs1800067 GG genotype were more likely to have an increased risk of glioma when compared with carriers of the A/A genotype in a co-dominant model, with an odds ratio (OR) [95% confidence interval (CI)] of 2.85 (1.14-7.76). However, we did not find an association with increased risk of glioma for the polymorphisms rs3136038, rs1799798, and rs2276466 in XPF. The combination genotype of the rs1800067 G allele and the rs2276466 G allele was associated with a moderate risk of glioma (OR = 1.71, 95%CI = 1.02-2.87). Our study suggests that the rs1800067 genetic variant of XPF functions in the development of glioma.

Abstract
Attenuated Salmonella typhimurium SL7207 was used as a carrier for a reconstructed DNA vaccine against Streptococcus agalactiae. A 1.02 kb DNA fragment, encoding for a portion of the surface immunogenic protein (Sip) of S. agalactiae was inserted into pVAX1. The recombinant plasmid pVAX1-sip was transfected in EPC cells to detect the transient expression by an indirect immunofluorescence assay, together with Western blot analysis. The pVAX1-sip was transformed by electroporation into SL7207. The stability of pVAX1-sip into Salmonella was over 90% after 50 generations with antibiotic selection in vitro while remained stable over 80% during 35 generations under antibiotic-free conditions. The LD50 of SL/pVAX1-sip was 1.7 × 10(11) CFU/fish by intragastric administration which indicated a quite low virulence. Tilapias were inoculated orally at 10(8) CFU/fish, the recombinant bacteria were found present in intestinal tract, spleens and livers and eventually eliminated from the tissues 4 weeks after immunization. Fish immunized at 10(7), 10(8) and 10(9) CFU/fish with different immunization times caused various levels of serum antibody and an effective protection against lethal challenge with the wild-type strain S. agalactiae. Integration studies showed that the pVAX1-sip did not integrate with tilapia chromosomes. The DNA vaccine SL/pVAX1-sip was proved to be safe and effective in protecting tilapias against S. agalactiae infection.

Abstract
Although the introduction of double-balloon enteroscopy has greatly improved the diagnostic rate, definite diagnosis of Meckel’s diverticulum far from the ileocecal valve is still impossible in most cases. We explored the role of magnetic resonance (MR) enterography in detecting bleeding from Meckel’s diverticulum that can not be confirmed via double-balloon enteroscopy. This study describes a case of male patient with bleeding from Meckel’s diverticulum diagnosed with MR enterography of the small intestine. No bleeding lesion was found via colonoscopy, anal enteroscopy, or oral colonoscopy. MR enterography of the small intestine revealed an occupying lesion of 3.0 cm in the lower segment of the ileum. The patient was transferred to the Department of Abdominal Surgery of our hospital for surgical treatment. During surgery, a mass of 3 cm × 2 cm was found 150 cm from the ileocecal valve, in conjunction with congestion and edema of the corresponding mesangium. Intraoperative diagnosis was small bowel diverticulum with bleeding. The patient underwent partial resection of the small intestine. Postoperative pathology showed Meckel’s diverticulum containing pancreatic tissues. He was cured and discharged 7 d after operation. We conclude that MR enterography of the small intestine has greatly improved the diagnosis rate of Meckel’s diverticulum, particularly in those patients with the disease which can not be confirmed via double-balloon enteroscopy.

Abstract
AIM: To assess the therapeutic value of endoscopic mucosal resection (EMR) under micro-probe ultrasound guidance for rectal carcinoids less than 1 cm in diameter.
METHODS: Twenty-one patients pathologically diagnosed with rectal carcinoids following colonoscopy in our hospital from January 2007 to November 2012 were included in this study. The patients consisted of 14 men and 7 women, with a mean age of 52.3 ± 12.2 years (range: 36-72 years). The patients with submucosal tumors less than 1 cm in diameter arising from the rectal and muscularis mucosa detected by micro-probe ultrasound were treated with EMR and followed up with conventional endoscopy and micro-probe ultrasound.
RESULTS: All of the 21 tumors were confirmed by micro-probe ultrasound as uniform hypoechoic masses originating from the rectal and muscularis mucosa, without invasion of muscularis propria and vessels, and less than 1 cm in diameter. EMR was successfully completed without bleeding, perforation or other complications. The resected specimens were immunohistochemically confirmed to be carcinoids. Patients were followed up for one to two years, and no tumor recurrence was reported.
CONCLUSION: EMR is a safe and effective treatment for rectal carcinoids less than 1 cm in diameter.

Abstract
AIM: To explore endoscopic therapy methods for gastric stromal tumors originating from the muscularis propria.
METHODS: For 69 cases diagnosed as gastric stromal tumors originating from the muscularis propria, three types of endoscopic therapy were selected, based on the size of the tumor. These methods included endoscopic ligation and resection (ELR), endoscopic submucosal excavation (ESE) and endoscopic full-thickness resection (EFR). The wound surface and the perforation of the gastric wall were closed with metal clips. Immunohistostaining for CD34, CD117, Dog-1, S-100 and smooth muscle actin (SMA) was performed on the resected tumors.
RESULTS: A total of 38 cases in which the tumor size was less than 1.2 cm were treated with ELR; three cases were complicated by perforation, and the perforations were closed with metal clips. Additionally, 18 cases in which the tumor size was more than 1.5 cm were treated with ESE, and no perforation occurred. Finally, 13 cases in which the tumor size was more than 2.0 cm were treated with EFR; all of the cases were complicated by artificial perforation, and all of the perforations were closed with metal clips. All of the 69 cases recovered with medical treatment, and none required surgical operation. Immunohistostaining demonstrated that among all of the 69 gastric stromal tumors diagnosed by gastroscopy, 12 cases were gastric leiomyomas (SMA-positive), and the other 57 cases were gastric stromal tumors.
CONCLUSION: Gastric stromal tumors originating from the muscularis propria can be treated successfully with endoscopic techniques, which could replace certain surgical operations and should be considered for further application.

Abstract
AIM: To investigate the endoscopic hemostasis for gastrointestinal bleeding due to Dieulafoy’s lesion.
METHODS: One hundred and seven patients with gastrointestinal bleeding due to Dieulafoy’s lesion were treated with three endoscopic hemostasis methods: aethoxysklerol injection (46 cases), endoscopic hemoclip hemostasis (31 cases), and a combination of hemoclip hemostasis with aethoxysklerol injection (30 cases).
RESULTS: The rates of successful hemostasis using the three methods were 71.7% (33/46), 77.4% (24/31) and 96.7% (29/30), respectively, with significant differences between the methods (P < 0.05). Among those who had unsuccessful treatment with aethoxysklerol injection, 13 were treated with hemoclip hemostasis and 4 underwent surgical operation; 9 cases were successful in the injection therapy. Among the cases with unsuccessful treatment with hemoclip hemostasis, 7 were treated with injection of aethoxysklerol and 3 cases underwent surgical operation; 4 cases were successful in the treatment with hemoclip hemostasis. Only 1 case had unsuccessful treatment with a combined therapy of hemoclip hemostasis and aethoxysklerol injection, and surgery was then performed. No serious complications of perforation occurred in the patients whose bleeding was treated with the endoscopic hemostasis, and no re-bleeding was found during a 1-year follow-up.
CONCLUSION: The combined therapy of hemoclip hemostasis with aethoxysklerol injection is the most effective method for gastrointestinal bleeding due to Dieulafoy’s lesion.

Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) has been used increasingly for the treatment of choledocholithiasis, gallstone pancreatitis, and benign or malignant bile duct or pancreatic duct stenosis. The purpose of this study was to evaluate ERCP for the diagnosis and therapy of biliary-pancreatic diseases. METHODS A total of 2075 patients who underwent diagnostic and therapeutic ERCP from June 2001 to March 2009 were analyzed retrospectively. Achievement and complication rates were calculated, and the therapeutic effect was observed. RESULTS In all the 64 cases who underwent diagnostic ERCP, the procedure was successful, in 2011 cases therapeutic ERCP was performed, and the success rate was 94.6%. In the therapeutic ERCP cases, 1434 (93.0%) were successful among the 1542 cases of choledocholithiasis, and 422 (90.0%) of the 469 cases with benign or malignant bile duct or pancreatic duct stenosis, or acute obstructive suppurative cholangitis with stent placement or endoscopic nasobiliary drainage were successful. Fifty-nine (90.8%) cases of the 65 who underwent a pre-cut for pancreatic sphincterotomy were successful. Complication rate was 5.1% and the most frequent complication was acute pancreatitis (4.4%). CONCLUSIONS ERCP is one of the major diagnostic and therapeutic methods for biliary-pancreatic disease. Therapeutic ERCP is a minimally invasive, safe and effective treatment method for various biliary-pancreatic diseases.

Abstract
AIM: To compare the clinical and imaging characteristics of autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC).
METHODS: A total of 43 patients with autoimmune hepatic diseases, who were treated at our hospital from October 2003 to February 2008, were included in this study. Of all patients, 12 had AIH, 19 had PBC and 12 had PSC. A retrospective analysis of the clinical and imaging characteristics of these patients was performed to observe the efficacy of drug therapy.
RESULTS: Females were more prone to AIH. Patients with AIH often had elevated transaminase, while those with PBC and PSC had elevated glutamyltransferase and alkaline phosphatase. The incidence rates of jaundice in patients with AIH, PBC and PSC were 42%, 80% and 91%, respectively, while those of pruitus were 38%, 68% and 79%, respectively. Proper use of ursodeoxycholic acid and immunodepressant could relieve symptoms and improve hepatic function within six months in 68% of patients.
CONCLUSION: Hepatic function abnormalities mainly manifest as elevated transaminase in patients with AIH, and cholestasis in patients with PBC or PSC. Use of ursodeoxycholic acid and immunodepressant could relieve symptoms and improve hepatic function in the majority of patients.

Abstract
BACKGROUND In the recent years, the incidence of esophageal cancer in China has increased. The key point for raising the survival rate is the diagnosis and treatment at an early stage. Narrow-band imaging (NBI) can enhance the contrast of the mucous membrane of the esophagus without staining. This study aimed to explore the value of NBI in the diagnosis of early esophageal cancer and precancerous lesions. METHODS The esophagus was examined with ordinary endoscopy and NBI endoscopy. Pit patterns and blood capillary forms were examined with routine magnifying endoscopy and NBI endoscopy. Finally, a 1.2% Lugoul's iodine solution was used to stain the esophageal mucosal surface and a biopsy was taken at all the sites where NBI or iodine staining was positive. NBI and iodine staining scales were compared with pathologic diagnosis, which was considered as the gold standard. RESULTS A total of 90 cases (138 lesions in total) were diagnosed as early esophageal cancer or precancerous lesions; 104 lesions (75.4%) were detected with ordinary endoscopy, 120 lesions (87.0%) were detected with NBI endoscopy, and 138 lesions (100%) were detected with iodine staining. The lesion detection rate of NBI was significantly lower than that of iodine staining (chi(2) = 17.176, P < 0.01). However, there was no significant difference between NBI and iodine staining for the diagnosis of high grade intraepithelial neoplasia (chi(2) = 1.362, P > 0.05), while the detection rate of NBI was significantly lower than that of iodine staining for the diagnosis of low grade intraepithelial neoplasia (chi(2) = 13.388, P < 0.01). The pit pattern and blood capillary form of early esophageal cancer and precancerous lesions could be demonstrated clearer with NBI than with ordinary endoscopy. CONCLUSIONS NBI can enhance the contrast of the mucous membrane of the esophagus without staining. The combination of NBI and iodine staining can raise the diagnostic rate of early esophageal cancer and precancerous lesions.

Abstract
BACKGROUND Hands-on endoscopy workshops are popular and valuable sources for the continuing medical education of endoscopists. Concerns, however, exist regarding clinical outcomes of procedures performed during hands-on training of ERCP. OBJECTIVE We compared the success rates and complications between patients in the hands-on training courses and matched control patients. DESIGN A retrospective, multicenter study. SETTING Seven endoscopy centers in mainland China. PATIENTS All patients who underwent ERCP during hands-on training courses at GI endoscopy conferences in China between January 2002 and December 2006 were included. MAIN OUTCOME MEASUREMENTS Clinical and endoscopic characteristics, including age, sex, indication, therapeutic intervention, success rate, and complication, were collected. Differences in ERCP outcomes between domestic and foreign mentors were also compared. Conference, patient, and endoscopist-related variables were analyzed for potential risk factors associated with post-ERCP complications. RESULTS Nine conferences with hands-on ERCP training, including 124 patients, were held at 7 endoscopy centers. There were no significant differences in the sex ratio, age, indication, and therapeutic intervention between patients for hands-on training (n = 124) and controls (n = 124). The success rates and overall complication rates were similar between the 2 groups (91.9% vs 92.7%, respectively, P = .811; 12.9% vs 9.7%, respectively, P = .422). Domestic mentors encountered more post-ERCP complications than foreign mentors (18.0% vs 0%, respectively, P = .001). Univariate analyses showed that a large-scale conference (P = .004), first-time mentorship (P = .015), and small case volume for the mentor (P = .015) were significantly associated with post-ERCP complications. Nominal significance in univariate testing was removed when analyzed in a comprehensive multivariate setting. LIMITATIONS A nonrandomized retrospective trial with only 7 centers (9 conferences). CONCLUSIONS The success rate and overall complication rate were similar between patients in the hands-on training and those who had routine ERCP procedures. A large-scale conference, first-time mentorship, and small case volume for the mentor may be associated with post-ERCP complications.

Abstract
OBJECTIVES Live demonstrations of endoscopic retrograde cholangiopancreatography (ERCP) have a high educational value and contribute significantly to endoscopy development and training. However, the success and safety of live demonstration have been questioned. The aim of this study was to evaluate the success rate and complications of therapeutic ERCP among patients who participated in live demonstrations. METHODS Patients who underwent therapeutic ERCP during live demonstrations at gastrointestinal endoscopy conferences in China between January 2002 and December 2007 were included. The matched control for each patient was a patient admitted to the same ERCP unit with similar indication, who received ERCP by an endoscopist with similar experience as those who performed the live demonstration. Patient's age, gender, indication, success rate, and complications of ERCP were collected and compared. ERCP outcomes between local and visiting faculty were also compared. RESULTS In total, 36 conferences with live ERCP demonstrations involving 406 patients were held in 14 endoscopy centers. There were no significant differences in patients' gender, age, and indications between live demonstrations and controls. The overall complication rate of ERCP in live demonstrations was not significantly different compared with controls (10.3% vs. 8.6%, P=0.473). However, the success rate was significantly lower in live demonstrations than in controls (94.1% vs. 97.5%, P=0.021). The success and complication rates of ERCP performed by local faculty, domestic visiting, and foreign visiting faculties were similar. CONCLUSIONS Although the success rate of therapeutic ERCP performed during live demonstrations was lower than that of routine procedures, the overall complication rate did not significantly increase. ERCP performed by visiting endoscopists was as safe as that done by local faculty in live demonstrations.

Abstract
SiCN nanowires are synthesized by pyrolysis of hexamethyldisilazane (HMDSN) using ferrocene as a catalyst precursor at 1200 degrees C in a flowing argon atmosphere on the surface of mullite substrate, polycrystalline alumina wafer and quartz tube. In oxygen-contained argon atmosphere, SiCN/SiO2 nanocables are synthesized. The as-synthesized products are characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and high-resolution electron microscopy equipped with energy dispersive X-ray spectroscopy. The lengths of the nanowires and nanocables are in the millimeter range. The diameter of the SiCN nanowires grown on mullite substrate and alumina wafer ranges from about 10-70 nm, while that of the nanowires grown on quartz tube surface is in the range of around 7-10 nm. The diameters of the SiCN/SiO2 nanocables are relatively large. A vapor-liquid-solid growth mechanism of the nanostructures is proposed. The electrical resistivity of a single SiCN/SiO2 nanocable is reported for the first time.

Abstract
AIM: To compare Fuji intelligent chromo endoscopy (FICE) and staining techniques in differential diagnosis for colonic tumor and non-tumor lesions.
METHODS: From March 2007 to May 2008, 245 patients with colon neoplasm or polypoid lesions were included. The patients underwent a magnifying ordinary colonoscopy, a magnifying FICE technique and magnifying staining technique. The pit pattern and blood capillary form of the lesions were examined, an endoscopic diagnosis was made and compared with the pathologic diagnosis.
RESULTS: A total of 480 neoplasms were detected in 245 patients. There was significant difference in detecting lesions between conventional magnifying endoscopy and FICE larger models (90.0% vs 98.8%, P < 0.01). FICE magnifying endoscopy better revealed mucosal structure of capillaries than staining magnifying endoscopy (P < 0.01), but there was not significant difference in revealing duct openings. FICE showed higher coincidence rate of diagnosis, higher sensitivity and specificity of the colorectal cancer than staining techniques (92.2% vs 81.0%, 95.3% vs 85.6%, 88.4% vs 75.6%, all P < 0.01).
CONCLUSION: FICE operates easily with higher coincidence rate of diagnosis and has a satisfactory clinical practical value in diagnosing colonic cancers.

Abstract
AIM: To assess endoscopic homeostasis method for gastrointestinal bleeding due to Dieulafoy lesion.
METHODS: Seventy-seven patients with gastrointestinal bleeding due to Dieulafoy lesion were treated with the following three kinds of endoscopic homeostasis methods: injecting therapy with aethoxysclerol (36 cases), endoscopic hemoclip homeostasis (21 cases), hemoclip hemostasis in combination with injecting therapy of aethoxysclerol (20 cases). The successful homeostasis rates and complication rates of the three approaches were assessed.
RESULTS: Successful homeostasis rates of the three approaches were 80.6%(29/36), 95.2%(20/21) and 100(20/20), respectively and a significant difference was detected (P < 0.05). 7 cases who failed with injecting therapy of aethoxysklerol were treated with hemoclip hemastasis. 5 cases succeeded and 2 cases failed and underwent further surgical operation. 1 case who failed with hemoclip homeostasis was later treated with injecting therapy of aethoxysklerol and bleeding was controlled. No serious complications including perforation occurred in patients using endoscopic hemostasis method and no re-bleeding occurred during half-year follow-up.
CONCLUSION: Hemoclip hemostasis in combination with injecting therapy of aethoxysklerol is the most effective method for gastrointestinal bleeding due to Dieulafoy lesion.

Abstract
BACKGROUND Esophagogastric variceal bleeding caused by cirrhosis is a kind of emergent condition in the clinic. This study was conducted to explore the therapeutic effect and superiority of embolization of gastric fundus varices combined with endoscopic variceal ligation (EVL) of esophageal varices for the treatment of patients with esophagogastric variceal bleeding caused by cirrhosis. METHODS Totally 172 patients were diagnosed by endoscopic examination within 24 hours of hospitalization with active gastric fundus variceal bleeding and grade II above esophageal varices caused by cirrhosis. Other causes leading to upper digestive tract bleeding were excluded. Patients were randomly divided into a control group (n = 82) and a therapy group (n = 90) following a random number table method. For the former, embolization for gastric fundus varices was performed, then an EVL for esophageal varices was performed 2 months later. For the therapy group, embolization for gastric fundus varices and EVL for esophageal varices were performed at the same time. RESULTS The rate of emergency hemostasis in the therapy group was 100.0%, higher than that in the control group (87.8%, P < 0.05). The rate of early rebleeding in the therapy group was 6.7% while the rate in the control group was 23.6% (P < 0.05). No complications related to treatment occurred in both groups. CONCLUSION Embolization for gastric fundus varices combined with EVL for esophageal varices is a safe and effective method for the treatment of patients with esophagogastric variceal bleeding caused by cirrhosis.
