Abstract
PURPOSE To compare the efficacy and safety of transcatheter arterial chemoembolization (TACE) in combination with tyrosinkinase inhibitors (TKI) and PD-1 inhibitors, versus TACE monotherapy for the treatment of ruptured hepatocellular carcinoma (HCC). MATERIALS AND METHODS This study included 104 patients with ruptured HCC receiving either combination therapy or TACE monotherapy at two centers between June 2015 and June 2022. Propensity score matching (PSM) analysis was used at a 1:2 ratio to reduce bias between the two groups. The primary outcome measures were overall survival (OS) and progression-free survival (PFS), and the secondary outcome measures were the occurrence of adverse events (AEs, Common Terminology Criteria for AEs, version 5.0.) and the peritoneal metastasis rate. RESULTS A total of 69 patients were enrolled after PSM, including 23 patients in the combination group and 46 patients in the monotherapy group. The combination group exhibited a significantly longer median OS (553 days, 95% confidence interval [CI] 222.6-883.9) compared to the monotherapy group (105 days, 95% CI 81.2-128.7; P < 0.001). Similarly, the combination group showed a better median PFS (356 days, 95% CI 299.5-412.4) compared to the monotherapy group (97 days, 95% CI 75.9-118.1; P < 0.001). Moreover, there was no significant difference in the peritoneal metastasis rate (combination group: 8.6% vs. monotherapy group: 26.1%, P = 0.119). Grade 3 AEs occurred at a rate of 21.7% and 13% in combination and monotherapy groups, respectively. No Grade 4/5 AEs were observed in either group. CONCLUSIONS Our study demonstrated that the combination of TACE with TKI and PD-1 inhibitors significantly enhances OS and PFS compared to TACE monotherapy in ruptured HCC patients. Furthermore, this combined approach exhibited an acceptable safety profile.

Abstract
BACKGROUND AND STUDY AIMS Esophageal restenosis is a serious complication after esophageal stent placement, which influences the clinical prognosis of stent implantation and the patient's quality of life. TGF-β1/Smads signaling pathway plays an important role in the development of the eosinophilic esophagitis and scar repair after skin trauma. However, the role of TGF-β1/Smads in the development of esophageal restenosis after esophageal stent placement remains unknown. Our study aimed to investigate whether TGF-β1/Smads plays an important role in the development of esophageal restenosis after esophageal stent, and whether the exogenous TGF-β1 inhibitor supplement could ameliorate the esophageal restenosis after esophageal stent. MATERIAL AND METHODS We established the model of esophageal restenosis after esophageal stenting in rats, and determined the expression levels of TGF-β1/Smads signaling pathway and the relevant markers of fibroblast activation by immunochemistry (IHC), Western Blot and real time qPCR. Those all the indicators were also determined in esophageal fibroblast when exposed to rhTGF-β1 with or without TGF-β1 inhibitor P144. RESULTS The serum level of IL-1β and TNFα were significantly increased in stent implantation group compared to blank control group, and obviously ameliorated when treated with P144. The TGF-β1/Smads signaling pathway and the relevant markers of fibroblast activation were significantly increased in stent implantation group compared to blank control group, and obviously ameliorated when treated with P144. Those all the indicators were significantly increased when exposed to rhTGF-β1, and obviously decreased when treated with P144. CONCLUSIONS TGF-β1 Inhibitor P144 could protect against benign restenosis after esophageal stenting by down-regulating the expression levels of relevant markers of fibroblast activation through TGF-β1/Smads signaling pathway inhibition, and may be used as a novel therapy for benign restenosis after esophageal stenting.

Abstract
The marked increase in the incidence rate of brucellosis is a serious public health concern in Jiangsu Province. However, its temporal and spatial distribution has not been studied in depth. The main purpose of this study is to depict the demographic, temporal and spatial distribution patterns and clustering characteristics of brucellosis cases in Jiangsu Province, China, from 2006 to 2021 to develop and implement effective scientific prevention and control strategies. Data for human brucellosis cases in Jiangsu Province from 2006 to 2021 were obtained from the Nationwide Notifiable Infectious Diseases Reporting Information System (NIDRIS). Spatial autocorrelation analysis and temporal-spatial scan statistics were used to identify potential changes in the spatial and temporal distributions of human brucellosis in Jiangsu Province. During the years 2006-2021, 1347 brucellosis cases were reported in Jiangsu Province, with an average annual incidence rate of 0.1036 per 100,000 individuals. Middle-aged and elderly individuals (aged 40-69 years) were the main infected populations, accounting for 69.72% (939/1347) of all reported cases. The incidence of brucellosis in Jiangsu showed a long-term increasing trend and displayed pronounced seasonal variations, with the peak occurring between April and June annually. The incidence gradually expanded from the northern and southern areas to the central areas between 2006 and 2021. Global spatial autocorrelation analysis demonstrated a positive correlation in the incidence of brucellosis between 2008 and 2012-2021. Temporal-spatial clustering analysis showed that the primary cluster was detected in the northern, highly endemic regions of Jiangsu, and the three secondary clusters were in areas where there had been outbreaks of brucellosis. Human brucellosis remains a serious public health issue in Jiangsu Province. Northern and southern Jiangsu regions, with high rates of brucellosis, may require special plans and measures to monitor and control the disease. Additionally, the capacity to respond to outbreaks in high-incidence areas should be improved to prevent further brucellosis outbreaks.

Abstract
To analyze the trend of abnormal birth weight of full-term newborns and its correlation with parental reproductive age in Chongqing municipality from 2010 to 2022. Based on the Chongqing Birth Certificate System, full-term newborns born from January 2010 to December 2022 were selected. Parental information and birth weight were abstracted from the system. The joinpoint regression model was used to assess the trend of incidence of low birth weight (LBW) and macrosomia in the offspring from 2010 to 2022. The logistic regression model was utilized to analyze the association between parental reproduction age and birth weight of newborns. The average birth weight of 3 155 542 newborns was (3 305.8±410.5) g. The joinpoint regression model showed a decreasing trend for the incidence of LBW from 2010 to 2016 (APC=-4.26%, P<0.05), and an increasing trend from 2020 to 2022 (APC=8.99%, P<0.05). The incidence of macrosomia exhibited a decreasing trend from 2015 to 2022 (APC=-3.37%, P<0.05). The logistic regression model showed that, compared to the group with parents aged 20-34 years, the risk of LBW increased in other age groups. The risk of macrosomia decreased when either parent was aged<20 years, and increased when both parents were aged≥20 years. In conclusion, from 2010 to 2022, the incidence of LBW in full-term offspring in Chongqing municipality decreased first and then increased, and the incidence of macrosomia increased first and then decreased. Both young and advanced parental age were associated with an increased risk of LBW in offspring, and advanced parental age was also associated with an increased risk of macrosomia in offspring. Attention should be paid to the effects of advanced maternal and paternal age on offspring birth weight. Further efforts to control childbearing at a young age were needed.

Abstract
BACKGROUND Patients with pancreatic cancer-caused biliary obstruction (PC-BO) have poor prognosis, but we lack of tools to predict survival for clinical decision-making. This study aims to establish a model for survival prediction among patients with PC-BO. METHODS A total of 172 patients with PC-BO treated with percutaneous biliary drainage were randomly divided into a training group (n = 120) and a validation group (n = 52). The independent risk factors for overall survival were selected to develop a Cox model. The predictive performance of M stage, hepatic metastases, cancer antigen 199, and the Cox model was determined. Naples prognostic score (NPS), the prognostic nutritional index (PNI), and the controlling nutritional status (CONUT) for 1-month mortality risk were compared with the Cox model. RESULTS The Cox model was developed based on total cholesterol, direct bilirubin, hepatic metastases, cancer antigen 199, stenosis type, and preprocedural infection (all P < 0.05), which named "COMBO-PaS." The COMBO-PaS model had the highest area under the curves (AUC) (0.801-0.933) comparing with other predictors (0.506-0.740) for 1-, 3-, and 6-month survival prediction. For 1-month mortality risk prediction, the COMBO-PaS model had the highest AUC of 0.829 comparing with NPS, PNI, and CONUT. CONCLUSION The COMBO-PaS model was useful for survival prediction among patients with PC-BO.

Abstract
PurposeTo compare the effectiveness and safety of transarterial chemoembolization (TACE) combined with apatinib and camrelizumab with those of TACE as well as apatinib among patients with unresectable hepatocellular carcinoma (HCC).Materials and methodsThe data of patients with unresectable HCC (uHCC) who received TACE-apatinib-camrelizumab combination (TACE + AC group) and TACE-apatinib combination (TACE + A group) were collected from two centers between January 2018 and January 2022. Propensity score matching (PSM) was conducted to diminish the bias between the two groups. The primary outcome measures of the study were overall survival (OS) and progression-free survival (PFS), and the secondary outcome measures were response rate (ORR), disease control rate (DCR), and adverse events (AEs).ResultsA total of 102 patients were enrolled in this study after PSM, with 34 patients in the TACE + AC group and 68 patients in the TACE + A group. Compared to the TACE + A group, TACE + AC had a significantly longer median OS (25.5 months, interquartile range [IQR], 23.5–33.0) than 18.5 months (IQR, 13.0–25.0; P = 0.001). Similarly, the PFS of the TACE + AC group was significantly improved (14.0 months, IQR, 9.0–NA) compared to that of the TACE + A group (5.0 months, IQR, 2.5–9.0; P = 0.001). The ORR rates (55.9% vs. 51.5%), and DCR rates (79.4% vs. 72.1%) were comparable between groups (P > 0.05). All treatment-related adverse events were tolerable and manageable, and no serious adverse events were observed.ConclusionTACE combined with apatinib plus camrelizumab demonstrated superior efficacy to TACE plus apatinib for patients with unresectable HCC. The two combination therapies showed similar safety profiles.

Abstract
Birth cohort is an important platform to study the effect of early-life exposure on health outcome, but large cohorts to investigate the effect of preconception exposure, especially paternal exposure, on reproductive health and birth outcome are limited. The Preconception Reproductive Health and Birth Outcome Cohort (PREBIC) is a prospective birth cohort study which pays equal attention to the contribution of environmental, psychological, behavioral as well as other factors to reproductive health and adverse birth outcomes in both men and women in Chongqing, China. PREBIC started in 2019 and plans to recruit 20 800 reproductive-age couples with child-bearing willingness. Followed up was conducted to understand the conception status of the women within two years. Women in pregnancy would be visited at first, second, third trimesters and after delivery. The offspring would be monitored until 2 years old to understand the incidences of preterm birth, low birth weight, birth defects, neurodevelopmental disorders and other outcomes. Related information and biospecimen collections (including semen, peripheral blood, urine, placenta, umbilical cord, cord blood and oral swab) were scheduled in each period. By January 2022, PREBIC had recruited 8 698 participants from all 38 districts in Chongqing. The goal of PREBIC is to establish one of the largest prospective preconception birth cohorts covering both men and women, which might provide a unique insight to understand the effects of the full reproductive cycle on reproductive health and adverse outcomes, with especial emphasis on preconception exposures.

Abstract
Purpose To compare the efficacy and safety of transcatheter arterial chemoembolization combined with microwave ablation (TACE–MWA) versus TACE alone for the treatment of recurrent small hepatocellular carcinoma (sHCC) after resection. Materials and methods From June 2015 to January 2020, a total of 45 patients with recurrent sHCC (size ≤ 3 cm) treated by TACE–MWA or TACE were included in this study. The radiological response at 1-, 3-, 6-month after initial treatment [modified Response Evaluation Criteria in Solid Tumors (mRECIST)], progression-free survival (PFS), overall survival (OS), and complications were evaluated. Results The TACE–MWA group showed better 1-, 3-, 6-month tumor response rates than TACE group. The corresponding 1-, 3-, and 5-year PFS rates were 76.5%, 70.6%, and 70.6% for the TACE–MWA group, and 56.1%, 15.0%, and 15.0% for the TACE group (P = 0.003). The 1-, 3-, and 5-year OS rates were 100.0%, 82.1%, and 61.5% for the TACE–MWA group, and 89.0%, 58.1%, and 50.8% for the TACE group (P = 0.389), respectively. Moreover, no major complications related to treatment were observed in either of the groups. Compared with the TACE group, the TACE–MWA group had a significantly lower number of re-TACE sessions (P = 0.003). Conclusions Although TACE alone provides equivalent effectiveness for recurrent sHCC in terms of OS rates, TACE–MWA had better 1-, 3-, 6-month tumor response rates and may prolong tumor PFS time.

Abstract
PURPOSE The purpose of the study was to compare self-expandable metallic stent placement with catheter drainage for malignant bilioenteric anastomotic stricture in terms of efficacy and safety. MATERIALS AND METHODS This study included 54 patients with malignant bilioenteric anastomotic stricture treated from March 2016 to February 2021. Twenty-seven patients underwent insertion of self-expandable metallic stent (Stent group); the remaining twenty-seven patients underwent internal-external catheter drainage (Catheter group). Technical success was defined as successful placement of stent or drainage catheter in the appropriate position; clinical success was defined as a 20% reduction in serum bilirubin within 1 week after the procedure, compared with baseline. Complications, duration to stent/catheter malfunction, and overall survival were evaluated. RESULTS Technical success was achieved in all patients in both groups. In the Stent group, 21 patients received one stent and the other 6 patients required two stents. Clinical success rates were similar between the groups [Stent group, 92.6% (25/27); Catheter group, 88.9% (24/27)]. There were no major complications. The median duration to stent/catheter malfunction was significantly longer in the Stent group (130 days) than in the Catheter group (82 days; P = 0.010). The median overall survival was also significantly longer in the Stent group (187 days) than in the Catheter group (118 days; P = 0.038). CONCLUSION Self-expandable metallic stent placement might be better than internal-external catheter drainage for malignant bilioenteric anastomotic stricture in terms of the duration before stent/catheter malfunction and patient survival.

Abstract
OBJECTIVE This study aims to evaluate the effectiveness and safety of hepatic arterial infusion chemotherapy (HAIC) following the simultaneous placement of self-expandable metallic stent (SEMS) and iodine-125 (125I) seed strands for the management of advanced cholangiocarcinoma (CCA) patients presenting with malignant obstructive jaundice (MOJ). METHODS Data from 74 patients with MOJ caused by advanced CCA treated with stent placement with 125I seed strands with or without HAIC between November 2015 and October 2020 were analysed retrospectively. Eighteen patients received 5 sessions of HAIC after SEMS placement with 125I seed strands (HAIC group), and 56 patients only underwent SEMS placement with 125I seed strands and served as controls (control group). HAIC consisted of infusions of gemcitabine (600-1000 mg/m2 given over 30 min) followed by oxaliplatin (60-100 mg/m2 given over 2 h), with an interval of 4 weeks. Propensity score matching (PSM) analysis was used to adjust for differences in the baseline characteristics of the groups (including age, total bilirubin, and serum alanine aminotransferase level). Overall survival (OS), stent patency, and adverse events were compared between the two groups. RESULTS OS and stent patency were significantly better in patients in the HAIC group than in those in the control group (median survival time: before PSM, 362 vs. 185 days, p = 0.005; after PSM, 357 vs. 183 days, p = 0.012; median duration of stent patency: before PSM, 294 vs. 156 days, p = 0.001; after PSM, 287 vs. 183 days, p = 0.039). All adverse reactions were controllable by temporary symptomatic treatment. Serious complications and treatment-related deaths were not observed. CONCLUSION Our preliminary study showed that HAIC following SEMS placement with 125I seed strands is effective and safe for the management of advanced CCA patients presenting with MOJ and could improve stent patency and patient survival.

Abstract
Abstract
Background
Psoriasis is a common chronic inflammatory condition associated with an increased risk of obesity and higher coronary atherosclerosis burden by coronary computed tomography angiography (CCTA). Prior studies have shown that the ability to expand subcutaneous adipose tissue (SAT) may serve to identify individuals at a lower risk of atherosclerotic cardiovascular disease. However, the relationship between abdominal SAT and high-risk subclinical coronary artery disease requires exploration.
Purpose
To characterize the relationship between abdominal SAT volume measured on low-dose computed tomography, and coronary artery disease assessed as noncalcified and lipid-rich necrotic core burden by CCTA in psoriasis.
Methods
We performed a cross-sectional study of 232 participants with psoriasis and without known cardiovascular disease. All participants underwent CCTA to characterize coronary artery disease burden and low dose abdominal computed tomography to quantify subcutaneous adipose tissue volumes. Fat depot volumes were first adjusted in a sex specific manner for each participant's body mass index in a linear regression model. The residual values from the sex stratified linear regression models were used for analyses. Coronary artery disease burden was quantified in the three main coronary arteries (QAngio, Medis, The Netherlands) and averaged. Analyses were performed with StataIC 16 (Stata Corp., College Station, TX, USA).
Results
Of the 232 participants, 92 (40%) were women and the average age was 50 years. In women, there was a positive correlation between abdominal SAT and systemic inflammation as assessed by hs-CRP (r=0.30; p=0.004) and GlycA (r=0.29; p=0.007) as well as total cholesterol (r=0.24; p=0.02) and LDL cholesterol (r=0.22; p=0.04). In men, abdominal SAT correlated with hs-CRP (r=0.18; p=0.04) and insulin resistance as assessed by the homeostatic model for insulin resistance (r=0.17; p=0.04). In models fully adjusted for traditional cardiovascular risk factors, abdominal SAT volume negatively associated with noncalcified and lipid-rich necrotic core burden in men (β=−0.17; p=0.03, β=−0.21; p=0.02, respectively), but not women (β=−0.04; p=0.72, β=0.05; p=0.68, respectively) with psoriasis (Table).
Conclusions
In psoriasis, for a given body mass index, abdominal SAT negatively associated with coronary atherosclerosis burden in men. The observed sex-specific effects on subclinical coronary artery disease warrant further study of abdominal SAT in states of chronic inflammation.

Abstract
Objective: To describe the distribution and characteristics of peripheral anterior synechiae (PAS) in patients with primary angle-closure glaucoma (PACG). Methods: Retrospective case study. A total of 285 PACG patients (406 eyes) diagnosed in the Eye Hospital, School of Ophthalmology and Optometry, Wenzhou Medical University from January 2017 to August 2019 were included. They were 102 males and 183 females, with a median age of 67 years old (range, 21 to 95 years old). The PAS range was detected by gonioscopy examination, and the frequency distribution of PAS at 12 clock points was counted by clockwise. The PAS distribution at the middle point of PAS with continuous distribution and ≤6 clock points was assessed. Results: In all cases, PAS of the right eye was concentrated at 11:00 to 4:00 regions [range, 62.0% (129/208) to 78.8% (164/208)]. PAS of the left eye was concentrated at 7:00 to 1:00 regions [range, 50.0% (99/198) to 75.8% (150/198)]. When the PAS range of the atrial angle was ≤6 clock regions, it was mainly at 12:00 to 3:00 [range, 58.3% (74/127) to 67.7% (86/127)] in the right eye and at 10:00 to 12:00 [range, 54.8% (68/124) to 66.1% (82/124)] in the left eye. Among 121 cases (242 eyes) with both eyes involved, the PAS region was at 11:00 to 5:00 [range, 52.1% (63/121) to 79.3% (96/121)] in the right eye and at 8:00 to 1:00 [range, 50.4% (61/121) to 76.9% (93/121)] in the left eye. When the PAS range of the atrial angle was ≤6 clock regions, it was mainly at 12:00 to 4:00 [range, 53.2% (41/77) to 71.4% (55/77)] in the right eye and at 10:00 to 12:00 [range, 50.6% (39/77) to 64.9% (50/77)] in the left eye. In all cases, there were 171 cases of right eyes and 175 cases of left eyes with continuous angle PAS. The central PAS clock position of the right eye was mainly at 11:00 to 3:00 [range, 15.2% (26/171) to 24.0% (41/171)], and that of the left eye was mainly at 8:00 to 12:00 [range, 15.4% (27/175) to 20.6% (36/175)]. Among cases with both eyes involved, there were 98 cases of right eyes and 104 cases of left eyes with continuous angle PAS. The clock distribution of the middle position of the right eye angle PAS was concentrated at 11:00 to 3:00 [range, 17.3% (17/98) to 26.5% (26/98)], and that of the left eye was concentrated at 8:00 to 12:00 [range, 13.5% (14/104) to 20.2% (21/104)]. Conclusions: The PAS of PACG patients is mainly located in the upper and nasal sides, and the closer to the temporal side, the smaller the PAS frequency, showing a gradual downward trend. The PAS distribution of binocular angles is of obvious mirror symmetry. (Chin J Ophthalmol, 2021, 57: 666-671).

Abstract
PURPOSE To evaluate the frequency and the degree of vital signs elevation, as well as to elucidate the risk factors for elevation of cardiopulmonary parameters. MATERIALS AND METHODS We retrospectively evaluated the medical records of 101 patients who received microwave ablation (MWA) under deep sedation with propofol. Univariate analysis followed by multivariate linear regression analysis was performed to determine the risk factors associated with the elevation of cardiopulmonary parameters. RESULTS The heart rate (HR), mean blood pressure (BP) and respiratory rate (RR) were elevated in 53.5%, 45.5% and 30.7%. Hyperhemodynamic state (mean BP or HR increased > 30% of the baseline) and high RR (RR > 20 times/min) were detected in 23.8% and 13.9%. Age ≤ 50 years was signifiant for mean BP and HR elevation (p = 0.032; p = 0.027), ablation zone abutting the parietal peritoneum (p = 0.001; p = 0.001; p < 0.001) and the diaphragm (p = 0.001) were risk factors for BP and RR elevation. CONCLUSIONS Elevations in HR and BP are common. Risk factors for vital signs elevation include ablation zone abutting the parietal peritoneum and the diaphragm, as well as young age. These findings help devise strategies for anesthetic management.

Abstract
Non-small cell lung cancer (NSCLC) is the leading cause of cancer-associated death worldwide. MicroRNA (miRNA)-32-5p is as an important cancer-associated miRNA in different types cancer. To date, the role of miR-32-5p in the migration and invasion of NSCLC remains unknown. In the present study, a Transwell assay was performed to investigate the role of miR-32-5p in lung adenocarcinoma. miR-32-5p expression level was determined via reverse transcription-quantitative PCR in 24 pairs of NSCLC and adjacent normal tissues. SMAD family member 3 (SMAD3) was considered as a novel target gene by luciferase reporter assay and western blot in NSCLC. The present study demonstrated that miR-32-5p is frequently downregulated in NSCLC tissues. The overexpression of miR-32-5p resulted in the inhibition of migratory and invasive abilities in NSCLC cells. Thus, SMAD3 was identified as a target of miR-32-5p, and its expression was negatively correlated with miR-32-5p expression in clinical NSCLC tissues. Overall, these findings indicate that miR-32-5p serves as a tumor suppressor by targeting SMAD3. Thus, miR-32-5p may be a potential therapeutic target for the treatment of lung adenocarcinoma.

Abstract
BACKGROUND Currently, side-by-side (SBS) and stent-in-stent (SIS) are the two main techniques for stent deployment to treat hilar biliary obstructions. Previous studies comparing these two techniques are very limited, and thus, no consensus has been reached on which technique is better. The purpose of this study is to compare the clinical efficacy and safety of SBS and SIS deployment via a percutaneous approach for malignant hilar biliary obstruction. METHODS From July 2012 to April 2019, 65 patients with malignant hilar biliary obstruction who underwent bilateral stenting using either the SBS or SIS techniques were included in this study. Among them, 27 patients underwent SIS stent insertion (SIS group), and the remaining 38 patients underwent SBS stent insertion (SBS group). Technical success, improvement of jaundice, complications, duration of stent patency, and overall survival were evaluated. RESULTS Technical success was achieved in all patients in the two groups. The serum bilirubin level decreased more rapidly 1 week after the procedures in the SBS group than in the SIS group (P = 0.02). Although the total complication rate did not differ between the two groups, cholangitis was found to be more frequent in the SIS group (P = 0.04). The median stent patency was significantly longer in the SBS group (149 days) than in the SIS group (75 days; P = 0.02). The median overall survival did not significantly differ between the two groups (SBS vs. SIS, 155 days vs. 143 days; P > 0.05). CONCLUSIONS Percutaneous transhepatic bilateral stenting using either the SBS or SIS technique is safe and effective in the management of malignant hilar biliary obstruction. However, SBS offers a quicker improvement of jaundice, a lower incidence of cholangitis after the procedure, and a longer stent patency period than SIS.

Abstract
Background Fluoroscopic or endoscopic placement of metallic stents is used as a safe, non-surgical, palliative treatment option for malignant gastroduodenal obstructions. However, endoscopic stent placement is not always feasible, due to the tight or tortuous stricture of the obstructed area and insufficient visualization of the stomach due to remnant food material. Purpose To assess the technical feasibility and clinical outcomes of fluoroscopic-guided stent placement in malignant gastroduodenal obstructions following the technical failure of endoscopic stent placement. Material and Methods In all, 19 patients (14 men, 5 women; age range, 36-85 years) were referred due to technical failures of tentative endoscopic stent placement. Indications were failure to pass the guide wire through the obstruction (n = 13), failure to reach the stricture lesion due to short endoscope (n = 5), and acute angulation of the stricture lesion (n = 1). Data were retrospectively collected regarding the technical and clinical success of the fluoroscopy, the dysphagia score before and after stent placement, and major complications and their management. Results Fluoroscopic stent placement was technically successful in 15/19 patients (79%). Failures were due to complete obstruction (n = 3) and acute angulation of the stricture lesion (n = 1). Clinical success was achieved in all 15 patients with successful stent placement. The dysphagia score significantly improved after stent placement ( P < 0.001). Complications occurred in 4/15 patients (27%), including tumor overgrowth (n = 2), stent collapse (n = 1), and jaundice (n = 1). Conclusion Fluoroscopic stent placement in malignant gastroduodenal obstructions following a technical failure of endoscopic stent placement is technically feasible and has an acceptable clinical outcome.

Abstract
OBJECTIVES To evaluate clinical outcomes of fluoroscopic removal of retrievable self-expandable metal stents (SEMSs) for malignant oesophageal strictures, to compare clinical outcomes of three different removal techniques, and to identify predictive factors of successful removal by the standard technique (primary technical success). METHODS A total of 137 stents were removed from 128 patients with malignant oesophageal strictures. Primary overall technical success and removal-related complications were evaluated. Logistic regression models were constructed to identify predictive factors of primary technical success. RESULTS Primary technical success rate was 78.8 % (108/137). Complications occurred in six (4.4 %) cases. Stent location in the upper oesophagus (P=0.004), stricture length over 8 cm (P=0.030), and proximal granulation tissue (P<0.001) were negative predictive factors of primary technical success. If granulation tissue was present at the proximal end, eversion technique was more frequently required (P=0.002). CONCLUSIONS Fluoroscopic removal of retrievable SEMSs for malignant oesophageal strictures using three different removal techniques appeared to be safe and easy. The standard technique is safe and effective in the majority of patients. The presence of proximal granulation tissue, stent location in the upper oesophagus, and stricture length over 8 cm were negative predictive factors for primary technical success by standard extraction and may require a modified removal technique. KEY POINTS • Fluoroscopic retrievable SEMS removal is safe and effective. • Standard removal technique by traction is effective in the majority of patients. • Three negative predictive factors of primary technical success were identified. • Caution should be exercised during the removal in those situations. • Eversion technique is effective in cases of proximal granulation tissue.

Abstract
OBJECTIVES The purpose of this study is to investigate the incidence and management of oesophageal ruptures following fluoroscopic balloon dilatation (FBD) in children with benign oesophageal strictures. METHODS Sixty-two children with benign oesophageal strictures underwent FBDs. Oesophageal rupture was categorized as intramural (type 1), transmural (type 2), or transmural with free leakage (type 3). The possible risk factors for oesophageal ruptures were analyzed. RESULTS One hundred and twenty-nine FBDs were performed in these patients. The oesophageal rupture rate was 17.1 % (22/129). The majority (21/22) of ruptures were type 1 and type 2, both were treated conservatively. Only one patient had a type 3 rupture and underwent oesophagoesophagostomy. The patient gender, age, and the length and cause of the stricture showed no significant effect on the rupture (P > 0.05). However, for the patients ≤2 years old, the initial balloon with a diameter ≥10 mm showed a higher oesophageal rupture rate than those <10 mm during the first session (P = 0.03). CONCLUSIONS Although the oesophageal rupture rate in children was 17.1 %, the type 3 rupture rate was 0.8 %, which usually requires aggressive treatment. For children ≤2 years old, the initial balloon diameter should be <10 mm in the first session for decreasing the risk of oesophageal rupture. KEY POINTS • The oesophageal rupture rate following balloon dilatation in children was 17.1 %. • The incidence of transmural rupture with free leakage is very low. • Only transmural rupture with free leakage needs aggressive treatment. • For children ≤2 years, the initial balloon diameter should be <10 mm.

Abstract
BACKGROUND As a pro-inflammatory cytokine, IL-33 has been demonstrated to play an important role in tumor progression. It is reported that IL-33 is highly expressed in the serum and tumor tissues of patients with gastric cancer. However, the function of IL-33 in gastric cancer remains elusive. We here tried to elucidate the effects of IL-33 on gastric cancer cell invasion and migration. METHODS Invasion assay and migration assay were performed to assess the effects of IL-33 on gastric cancer cell invasion and migration. ST2 receptor was silenced by siRNA, and ERK1/2 pathway was inhibited by U0126. Protein levels of MMP-3 and IL-6 in cell supernatant were measured by ELISA. RESULTS IL-33 promoted the invasion and migration of gastric cancer cells, in a dose-dependent manner. Knockdown of the IL-33 receptor ST2 attenuated the IL-33-mediated invasion and migration. Furthermore, via ST2 receptor, IL-33 induced the activation of ERK1/2 and increased the secretion of MMP-3 and IL-6. In addition, blockage of ERK1/2 pathway resulted in inhibition of invasion and migration induced by IL-33, and downregulation of MMP-3 and IL-6 production. CONCLUSIONS IL-33 promotes gastric cancer cell invasion and migration by stimulating the secretion of MMP-3 and IL-6 via ST2-ERK1/2 pathway. Thus, IL-33 may be a useful marker for the diagnosis and treatment of gastric cancer.

Abstract
Herein, we report a new technique that consists of placing two 125I seed strands and two stents in the right and left intrahepatic bile ducts for the treatment of hilar cholangiocarcinoma. A 75-year-old man presented with jaundice and was diagnosed with Bismuth type IV Klatskin tumor. Abdominal computed tomography (CT) showed intrahepatic and extrahepatic bile duct dilatation and a soft tissue mass in the hepatic hilum. Because curative surgical resection was not possible, we placed 125I seed strands and stents in the right and left intrahepatic bile ducts. Three months later, abdominal CT showed less intrahepatic and extrahepatic bile duct dilatation than before the procedure. This technique was feasible and could be considered for the treatment of patients with Bismuth type IV tumors.

Abstract
PURPOSE To evaluate the clinical effectiveness of a newly designed stent for the treatment of malignant distal duodenal stenosis. METHODS From March 2011 to May 2013, six patients with malignant duodenal stenosis underwent fluoroscopically guided placement of the new duodenal stent consisting of braided, nested stent wires, and a delivery system with a metallic mesh inner layer. Primary diseases were pancreatic cancer in three patients, gastric cancer in two patients, and endometrial stromal sarcoma in one patient. Duodenal obstructions were located in the horizontal part in two patients, the ascending part in two patients, and the duodenojejunal flexure in two patients. Technical success, defined as the successful stent deployment, clinical symptoms before and after the procedure, and complications were evaluated. RESULTS Technical success was achieved in all patients. No major complications were observed. Before treatment, two patients could not take any food and the gastric outlet obstruction scoring system (GOOSS) score was 0; the other four patients could take only liquids orally (GOOSS score = 1). After treatment, five patients could take soft food (GOOSS score = 2) and one patient could take a full diet (GOOSS score = 3). The mean duration of primary stent patency was 115.7 days. CONCLUSIONS The newly designed stent is associated with a high degree of technical success and good clinical outcome and may be clinically effective in the management of malignant distal duodenal obstruction.

Abstract
AIM: To evaluate the clinical results of angiography and embolization for massive gastrointestinal hemorrhage after abdominal surgery.
METHODS: This retrospective study included 26 patients with postoperative hemorrhage after abdominal surgery. All patients underwent emergency transarterial angiography, and 21 patients underwent emergency embolization. We retrospectively analyzed the angiographic features and the clinical outcomes of transcatheter arterial embolization.
RESULTS: Angiography showed that a discrete bleeding focus was detected in 21 (81%) of 26 patients. Positive angiographic findings included extravasations of contrast medium (n = 9), pseudoaneurysms (n = 9), and fusiform aneurysms (n = 3). Transarterial embolization was technically successful in 21 (95%) of 22 patients. Clinical success was achieved in 18 (82%) of 22 patients. No postembolization complications were observed. Three patients died of rebleeding.
CONCLUSION: The positive rate of angiographic findings in 26 patients with postoperative gastrointestinal hemorrhage was 81%. Transcatheter arterial embolization seems to be an effective and safe method in the management of postoperative gastrointestinal hemorrhage.

Abstract
Here we demonstrate the material's synthetic feasibility for semiconducting alloyed silicon-tin nanocrystals (SiSn-NCs) with quantum confinement effects. An environmentally friendly synthesis is achieved by ns laser ablation of amorphous SiSn in water at ambient conditions. Plasmas generated in the liquid by laser pulses are characterized by spatial confinement with very high pressure (GPa), which allowed the growth of the SiSn-NCs via kinetic pathways. We further illustrate that surface engineering by a direct-current atmospheric pressure microplasma is capable of tailoring the SiSn-NCs surface properties without the need for lengthy surfactants, resulting in room temperature photoluminescence (PL); the PL peak wavelength is red-shifted by more than 250 nm with respect to the PL peak wavelengths observed for comparable elemental silicon nanocrystals.

Abstract
Background and Purpose This study evaluated the clinical value of detachable-balloon embolization for traumatic carotid-cavernous fistula (TCCF), focusing on the frequency, risk factors, and retreatment of recurrence. Methods Fifty-eight patients with TCCF underwent transarterial detachable-balloon embolization between October 2004 and March 2011. The clinical follow-up was performed every 3 months until up to 3 years postprocedure. Each patient was placed in either the recurrence group or the nonrecurrence group according to whether a recurrence developed after the first procedure. The relevant factors including gender, fistula location, interval between trauma and the interventional procedure, blood flow in the carotid-cavernous fistula, number of balloons, and whether the internal carotid artery (ICA) was sacrificed were evaluated. Results All 58 TCCFs were successfully treated with transarterial balloon embolization, including 7 patients with ICA sacrifice. Recurrent fistulas occurred in seven patients during the follow-up period. Univariate analysis indicated that the interval between trauma and the interventional procedure (p=0.006) might be the main factor related to the recurrence of TCCF. The second treatments involved ICA sacrifice in two patients, fistula embolization with balloons in four patients, and placement of a covered stent in one patient. Conclusions Detachable balloons can still serve as the first-line treatment for TCCFs and recurrent TCCFs despite having a nonnegligible recurrence rate. Shortening the interval between trauma and the interventional procedure may reduce the risk of recurrence.

Abstract
This study aimed to enhance the antibacterial activity of tilmicosin by solid lipid nanoparticles (SLN). Tilmicosin-loaded hydrogenated castor oil (HCO)-SLN was prepared using a hot homogenisation and ultrasonication method. The physicochemical characteristics of SLN were investigated by scanning electron microscopy (SEM) and photon correlation spectroscopy (PCS). The antibacterial activity of tilmicosin-SLN against Staphylococcus aureus was evaluated by growth inhibition and colony-counting method. A therapeutic study of tilmicosin-SLN was conducted by subcutaneous injection in a mouse mastitis model infected with S. aureus by teat canal infusion. Therapeutic efficacy was assessed by physical appearance of the mammary gland and measurement of colony-forming units (CFU) per gland. The results showed that the diameter, polydispersivity index, zeta potential, encapsulation efficiency and loading capacity of the nanoparticles were 343±26 nm, 0.33±0.08, -7.9±0.4 mV, 60.4±3.3% and 11.2±0.47%, respectively. Tilmicosin-SLN showed a sustained-release effect and sustained and enhanced antibacterial activity in vitro. SLN significantly enhanced the therapeutic efficacy of tilmicosin determined by lower CFU counts and a decreased degree of inflammation. These results demonstrated that the HCO-SLN is an effective carrier to enhance the antibacterial activity of tilmicosin.

Abstract
OBJECTIVE To determine the effect, safety, and feasibility of embolization of high flow arteriovenous malformations (AVMs) with HepaSphere microspheres. METHODS HepaSphere particles swell by absorbing fluids and become soft and deformable with a precisely calibrated diameter. 13 patients with AVMs were treated by transarterial embolization with HepaSphere particles. 3 cases underwent a following AVMs resection surgery. The follow-up period was 3 months to 3 years. Symptoms improvement and image examination were studied. RESULTS 28 transarterial embolizations were performed in 13 cases. The resection operation was performed in 3 cases after transarterial embolizations. The symptoms in diffused AVMs improved after several transarterial embolizations. Histologically, HepaSphere particles penetrated into the intralesional vessels and conformed to the vessel lumen, resulting in vessel occlusion. Minimal perivascular reaction was observed. CONCLUSIONS Embolization of high flow AVMs with HepaSphere microspheres is safe and effective. Combined treatment is necessary for diffuse AVMs.

Abstract
Flocculation behavior and mechanism of the exopolysaccharide secreted by Pseudoalteromonas sp. SM9913 (EPS SM9913), a psychrophilic bacterium isolated from 1855m deep-sea sediment, has been studied in this paper. EPS SM9913 showed a peak flocculating activity of 49.3 in 1g/L kaolin suspension with 4.55mmol/L CaCl2 and the optimum pH range of 5-8. It appears that the flocculating activity of EPS SM9913 was stimulated by Ca2+ and Fe2+. This study found that EPS SM9913 showed a better flocculation performance than Al2(SO4)3 at salinity of 5-100 per thousand or temperatures of 5-15 degrees C. In addition, this EPS was effective to flocculate several other suspended solids. The measured zeta-potentials, the size of flocs formed during the flocculation process and the surface profile of flocs revealed by scan electron micrograph suggest that bridging is the main flocculation mechanism of the studied EPS. Deacetylation of EPS SM9913 resulted in a significant decrease in its flocculating activity indicating that the large number of acetyl groups in EPS SM9913 played an important role in its flocculation performance.

Abstract
In this study, the decolorization of textile wastewater using composite flocculants was examined. It was composed of Fe(III) flocculants and polydimethyldiallylammonium chloride (PDMDAAC). The color removal efficiency of the composite flocculants was compared with that of individual flocculants, ferric chloride (FeCl3), polyferric chloride (PFC) and PDMDAAC, respectively. The results showed that the composite flocculants were more efficient than individual ones in color removal. The color removal efficiency of the composite flocculants was found to be related to the weight percentage of PDMDAAC (Wp), basicity (B) of PFC and molecular weight (MW) of PDMDAAC. The removal rate is higher at a larger Wp and MW value and lower B value. Chemical oxygen demand (COD) removal from textile wastewater was also investigated in this study. During color removal by the composite flocculants, only up to 20% COD could be removed from the textile wastewater. FeCl3 was then used to further remove the remaining COD from the decolorized wastewater. This two-step treatment of textile wastewater could achieve a 91.6% reduction in COD and an 88.9% reduction in color.

Abstract
Formation mechanism of H2Ti3O7 nanotubes by single-step reaction of crystalline TiO2 and NaOH has been investigated via transmission electron microscopy examinations of series specimens with different reaction times and extensive ab initio calculations. It was found that the growth mechanism includes several steps. Crystalline TiO2 reacts with NaOH, forming a highly disordered phase, which recrystallized into some H2Ti3O7 thin plates. H-deficiency on the top surface leads to an asymmetrical environment for the surface Ti3O2-7 layer. The calculations of the surface tension, elastic strain energy, interlayer coupling energy, and Coulomb force indicated that the asymmetrical environment is the principal driving force of the cleavage of the single sheets of H2Ti3O7 from the plates and the formation of the multiwall spiral nanotubes.

Abstract
We have attempted to develop a system for specific enhancement of transgene expression, which has been one of the most important issues in human gene therapy. When an Epstein-Barr virus (EBV) nuclear antigen 1 (EBNA-1) expression vector, pCMV-trEBNA-1, was cotransfected with an origin of latent viral DNA replication (oriP)-harboring plasmid, poriP-CMV-luciferase, luciferase gene expression was up to 20 times greater than in the absence of EBNA-1. This enhancement was regulated mainly at the transcriptional level and was dependent on the oriP sequence and the amount of EBNA-1. However, cointroduction of poriP-CMV-luciferase with purified recombinant EBNA-1 inhibited luciferase gene expression whereas no inhibition was observed when pCMV-luciferase was cointroduced with recombinant EBNA-1. We also introduced poriP-CMV-luciferase into mouse liver via the use of HVJ (hemagglutinating virus of Japan)-liposomes. By 10 days after transfer, luciferase gene expression was decreased to low levels. We then introduced pCMV-trEBNA-1 to mouse liver via HVJ-liposomes on day 10. Luciferase gene expression was reactivated, whereas no reactivation was detected by the injection of EBNA-1 expression plasmid into liver injected with pCMV-luciferase lacking the oriP sequence. Thus, cotransfection of oriP-harboring expression vector with EBNA-1 expression plasmid should be promising for human gene therapy, although the safety of the system must be investigated thoroughly.

Abstract
An RNA melanoma vaccine was investigated to induce protective immunity in a mouse-melanoma model. LacZ mRNA was synthesized in vitro by pSFV3 expression vector and introduced into the spleen of mice, using HVJ-liposomes. A high level of beta-galactosidase activity was detected for 10 days in mouse spleen. The human melanoma-associated antigen gp100 mRNA was synthesized in vitro by pSFV3 vector and encapsulated in HVJ-liposomes. Immunization by direct injection of the gp100 mRNA HVJ-liposomes into mouse spleen induced both anti-gp100 Ab and CTL responses against B16 melanoma. Immunization by administration of gp100 mRNA into the spleen delayed tumor growth and significantly prolonged survival compared with control treated mice. These preclinical studies demonstrate that an RNA tumor antigen vaccine strategy has potential application for human cancer treatment and prevention.

Abstract
DNA-based vaccine immunization effectively induces both humoral and cell-mediated immunity to antigens and can confer protection against numerous infectious diseases as well as some cancers. Human and mouse melanomas consistently express the tumor-associated antigen interacted with the melanogenesis pathway. Gp100 is immunogenic and has been shown to induce both antibody and cytotoxic T cell (CTL) responses in humans. To explore the potential use of DNA immunization to induce melanoma-specific immune responses, we assessed HVJ-AVE liposome incorporated with plasmid DNA encoding human gp100. The gp100 DNA vaccine was used in a mouse melanoma model to assess immunity against the B16 melanoma of C57BL/6 mice. Intramuscular injection of the DNA-HVJ-AVE liposomes induced both anti-gp100 antibody and CTL responses. Gp100 DNA-HVJ-AVE liposome immunization significantly delayed tumor development in mice challenged with B16 melanoma cells. Mice immunized with gp100 DNA-HVJ-AVE liposomes survived longer compared with control mice immunized with HVJ-AVE liposome alone. These results indicate that immunization with human gp100 DNA by HVJ-AVE liposomes can induce protective immunity against melanoma in this pre-clinical mouse model. This strategy may provide an effective approach for vaccine therapy with tumor-associated antigens against human melanoma.

Abstract
Efficacy and side effects following the immunization with Salmonella typhi Vi capsular polysaccharide vaccine (Vi) were assessed. The diluted solution (DS) of Vi was used as placebo. A total number of 777 children and adults were observed for side effect response. Mild and moderate fever appeared 16.93% and 0.05% in Vi group, 15.01% and 0.03% in DS group, respectively (statistically significant). Two cases with mild local reaction were observed in Vi group. A total number of 81,506 vaccinees were investigated on the efficacy of Vi vaccine, using positive blood culture of Salmonolla typhi as a diagnostic criterion. The protective rate and index of vaccine were 71.35% and 3.49% respectively. If 2 cases of positive Widal's test were included in, the protective rate would come up to 78.17% with a protective index 4.85. Clinical data showed that fever seen in the cases in Vi group was much lower than that of DS group. The systematic and local reaction of Vi vaccine were mild. The vaccine is safe and has high protective rate. It can also decrease the degree of fever with only one single dose as primary immunization. We believe Vi vaccine may serve as a vaccine of new generation to be promoted.

Abstract
Forty-seven renal biopsies of glomerulonephropathy with persistent Australian antigenaemia (HBsAg is mostly positive) were studied with light microscope, electron microscope and direct immunofluorescence. Immunohistochemical method (ABC method) was used to examine HBsAg, HBeAg and HBcAg deposits in renal tissue. In addition 20 cases of idiopathic membranous nephropathy (MN) were studied for comparison. These 47 cases included 19 children and 28 adults. The results indicated that Australian antigens diffusely deposited in glomeruli in 14 cases (29.7%), with HBsAg in 7 cases (50.0%), HBeAg in 13 cases (92.8%) and HBcAg in 2 cases (14.3%). The 14 positive cases included 11 children and 3 adults. The pathologic types were membranous nephropathy in 12 and membranoproliferative glomerulonephritis in 2 cases. The membranous type was characterized by irregular thickening of capillary wall and double contour, bubble-like appearance and spike formation of glomerular basement membrane (GBM); immune complexes and electron dense deposits may be present in different sites of glomeruli. Coarse granular deposits of IgG and C3 along GBM were the principal pattern, but IgA, IgM and C1q were often present. Among the 20 idiopathic MN, 2 were found to have HBeAg deposition along GBM, one was a child and the other an adult IgG, IgA, IgM, C3 and C1q with HBeAg deposits were present in glomeruli.
