Abstract
Objective: To study the clinical efficacy of sequential glucocorticoids in the treatment of acute mercury poisoning complicated with interstitial pneumonia. Methods: Retrospective analysis of 37 patients with acute mercury poisoning complicated with interstitial pneumonia admitted from January 2009 to April 2019, including the sequential treatment group (15 cases) and the conventional treatment group (22 cases) , all patients were treated with sodium dimercaptopropane sulfonate, and given anti-inflammatory, liver-protecting and other drugs for symptomatic treatment. The conventional treatment group was given methylprednisolone 1mg/kg once a day for 5-7 days. The sequential treatment group was given 1 mg/kg of methylprednisolone once a day for 5-7 days, then gradually reduced to 20 mg, and the total course of treatment was 14-21 days. To observe the changes of clinical symptoms, signs, lung function including forced vital capacity (FVC) , forced expiratory volume in the first second (FEV(1)) and ratio of forced expiratory volume in the first second to forced vital capacity (FEV(1)/FVC) , and chest CT indexes before and after treatment in the two groups. Results: The clinical symptoms and signs of the two groups were significantly improved compared with those before treatment, and there was no significant difference between the apparent efficiency and the total effective rate of the two groups (P>0.05) . The FVC, FEV(1), and FEV(1)/FVC of the two groups were significantly higher than those before treatment. After treatment, the indexes of the sequential treatment group were significantly higher than that of the conventional treatment group, and the difference was statistically significant (P<0.05) . The apparent efficiency (93.3%, 14/15) of CT lesions in the sequential treatment group was significantly higher than those of the conventional treatment group (59.1%, 13/22) , and the difference was statistically significant (P< 0.05) . Conclusion: Sequential glucocorticoid treatment of acute mercury poisoning complicated with interstitial pneumonia could improve the effect of clinical signs and symptoms which is equal to conventional treatment, but it could better promote the recovery of lung function and the absorption of lung lesions.

Abstract
AIMS The aim of the study was to investigate the isomerization of linoleic (LA) and linolenic acids (LNAs) into their conjugated isomers by Propionibacterium freudenreichii DSM 20270 and utilize this feature for microbial enrichment of blackcurrant press residue (BCPR) with health-beneficial conjugated fatty acids. METHODS AND RESULTS First, the ability of P. freudenreichii to isomerize 0·4 mg ml-1 of LA and LNA was studied in lactate growth medium. Free LA and α-LNA were efficiently converted into conjugated linoleic (CLA) and α-linolenic acid (α-CLNA), being the predominant isomers c9,t11-CLA and c9,t11,c15-CLNA, respectively. The bioconversion of α-LNA by P. freudenreichii was more efficient in terms of formation rate, yield and isomer-specificity. Thereafter, free LA and LNAs obtained from hydrolysed BCPR neutral lipids, by lipolytically active oat flour, were subjected to microbial isomerization in BCPR slurries. In 10% (w/v) slurries, a simultaneous enrichment in c9,t11-CLA and c9,t11,c15-CLNA of up to 0·51 and 0·29 mg ml-1 was observed from starting levels of 0·96 mg LA ml-1 and 0·37 mg α-LNA ml-1 respectively. CONCLUSIONS This study shows that growing cultures of P. freudenreichii DSM 20270 are able to simultaneously enrich BCPR with health-beneficial conjugated isomers of LA and α-LNA. SIGNIFICANCE AND IMPACT OF THE STUDY This study demonstrates that microbial isomerization technique can be utilized to enrich lipid-containing plant materials with bioactive compounds and thereby enable valorization of low value plant-based side streams from food industry into value-added food ingredients.

Abstract
OBJECTIVE In recent years, studies have shown that lncRNA plays an essential regulatory role in biological life activities. In disease and cancer research, the function of lncRNA is closely related to inflammatory response, tumor formation and cellular metabolism. Breast cancer is one of the most common malignant tumors in women. The research on the pathogenesis of breast cancer is the focus of current research. Although the regulatory mechanisms of some lncRNAs have been proven, the complexity of cancer regulation has led to incomplete research. MATERIALS AND METHODS The expression of LOXL1-AS1 and miR-143-3p was measured using qRT-PCR. Western blot was used to detect CDK, Cyclin D1, MMP-2, MMP-9, Bcl-2, Bax and Cleaved caspase-3 protein expression. MTT assay and transwell assay were applied to analyze cell proliferation, migration and invasion, respectively. Cell apoptosis rate of transfected cells was measured with flow cytometry. Luciferase reporter assay was applied to verify the relationship between LOXL1-AS1 and miR-143-3p. RESULTS In this study, we found that LOXL1-AS1 expression was induced while miR-142-3p expression was decreased in breast cancer tissues and cells, implying that LOXL1-AS1 and miR-143-3p play an important role in cell progression of breast cancer. Further investigation showed that silencing LOXL1-AS1 inhibited proliferation, promoted cell apoptosis and decreased the capacity of cell migrated and invasive in breast cancer cells. The analysis of luciferase reporter assay determined that LOXL1-AS1 directly targeted miR-143-3p in breast cancer cells. The rescue experiments further proved that miR-143-3p reversed the inhibited effects of si- LOXL1-AS1 on breast cancer cells. CONCLUSIONS In this study, we verified that LncRNA LOXL1-AS1 inhibited cell proliferation, migration and invasion as well as induced apoptosis in breast cancer via regulating miR-143-3p, providing a novel therapeutic target and improving understanding of the regulatory mechanism of cell progression in breast cancer.

Abstract
OBJECTIVE To elucidate the potential function of long non-coding RNA (lncRNA) TUG1 in the progression of diabetic nephropathy (DN) and the underlying mechanism. MATERIALS AND METHODS Rat diabetes mellitus (DM) model was established by streptozocin (STZ) administration. In vivo levels of TUG1 and relative genes in the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) pathway in DM rats and control rats were determined by the quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Moreover, levels of kidney weight, 24 h-urine protein, blood urea nitrogen and serum creatinine in DM rats and controls were detected. Mesangial cells were subjected to induction of high-level glucose. Relative levels of TUG1 and relative genes in the PI3K/AKT pathway in mesangial cells were determined as well. Through Cell Counting Kit-8 (CCK-8) and 5-Ethynyl-2'-deoxyuridine (EdU) assay, the regulatory effect of TUG1 on the proliferative ability of mesangial cells induced with high-level glucose was evaluated. Finally, expression changes in the PI3K/AKT pathway and extracellular matrix (ECM)-related genes in mesangial cells were determined. RESULTS TUG1 was downregulated in DM rats and mesangial cells induced with high-level glucose. Compared with controls, DM rats presented higher levels of kidney weight, 24 h-urine protein, blood urea nitrogen and serum creatinine, which were markedly reduced after TUG1 overexpression in vivo. Moreover, overexpression of TUG1 downregulated TGF-β1, FN, and COL-IV, and inhibited the activation of the PI3K/AKT pathway. CONCLUSIONS TUG1 is downregulated in DN. The overexpression of TUG1 could suppress the proliferation and ECM accumulation of mesangial cells via inhibiting the PI3K/AKT pathway.

Abstract
The neonatal or infant period is a critical stage for the development of brain neuroplasticity. Early life stresses in the neonatal period, including neonatal maternal separation (NMS), have adverse effects on an increased risk of psychiatric disorders in juveniles and adults. However, the underlying molecular mechanisms are not largely understood. Here, we found that juvenile rats subjected to 4 h daily NMS during postnatal days 1 to 20 exhibited autistic-like behavioral deficits without impairments in learning and memory functions. Molecular mechanism studies showed that oxytocin receptor (OXTR) in the medial prefrontal cortex of NMS rats was evidently downregulated when compared with control pups, especially in neurons. Erk/MAPK signaling, the downstream coupling signaling of OTXR, was also inhibited in NMS juvenile rats. Treatment with oxytocin could relieve NMS-induced social deficit behaviors and activated phosphorylation of Erk/MAPK signaling. Furthermore, medication with the inhibitor of H3K4 demethylase alleviated the abnormal behaviors in NMS rats and increased the expression of OXTR in the medial prefrontal cortex, which showed an epigenetic mechanism underlying social deficits induced by NMS. Taken together, these findings identified a molecular mechanism by which disruptions of mother-infant interactions influenced later displays of typical social behaviors and suggested the potential for NMS-driven epigenetic tuning of OXTR expression.

Abstract
BACKGROUND Molar Incisor Malformation (MIM) or Molar Root Incisor malformation (MRIM) is a recently discovered root malformation with constricted pulp and abnormally located furcation presented in permanent first molars and sometimes incisors. CASE REPORT Two cases that feature MIM are presented with the description of the characteristic tooth form, clinical/radiographic examination, medical history, the supposed aetiology, treatment procedure and results at the 2-year follow-up. Conservative endodontic treatment was performed in both cases, furcation perforation and canal perforation were filled with MTA (Mineral Trioxide Aggregate), and a good prognosis was observed after 2 years of follow-up. Furthermore, recommended treatment options are discussed to provide a more appropriate treatment for the patients. CONCLUSION Patients with MIM need to be treated at the right time to avoid severe infection and other problems. Early diagnosis with appropriate treatment is more likely to lead to a more favourable prognosis.

Abstract
Objective: To investigate the clinical value of holographic multimodal real-time three-dimensional navigation (3D-HMRN) technology for navigation and localization of pulmonary micro lesions. Methods: A total of 152 patients who underwent thoracoscopic partial resection of small pulmonary nodules in the Department of Thoracic Surgery of the First Medical Center of Chinese PLA General Hospital from June 2017 to December 2019 were retrospectively collected and were divided into two groups by computer random number. The experimental group consists of 76 patients (31 males and 45 females) with a mean age of (47±17) years. CT scan in lateral position navigation mode and 3D reconstruction of the surgical area were performed on all patients. Before the operation, holographic multimodal real-time 3D navigation technology was used to guide the puncture of the lesion. After the operation was completed, the intraoperative CT was used to verify the location of the puncture and determine the accuracy and error rang of the puncture. The control group consists of 76 patients (34 males and 42 females) with a mean age of (50±19) years. Intraoperative CT positioning was directly subjected to the patients. And then, the localization data of the two groups were compared and statistically analyzed. Results: Seventy-six cases of positioning puncture using navigation technology, the first success rate was 97.4%, the error was (3.9±0.9) mm, and the average operation time was (4.4±1.2) min; while the success rate of one-time CT positioning during routine surgery was 98.7%, the error was (3.5±1.0) mm, and the average operating time was (10.7±2.6) min. Compared with intraoperative CT positioning, the success rate and positioning accuracy of 3D-HMRN were not statistically significant (both P>0.05), however the operation time was significantly shortened (P<0.01). Conclusion: The holographic multi-modal real-time 3D navigation technology saves time and has accurate positioning, which may be used as an effective method for localization of pulmonary micro nodules during surgical treatment.

Abstract
OBJECTIVE C-terminal-binding protein interacting protein (CtIP) participates in a variety of DNA metabolisms and DNA double strand break repair (DSBR). The role of CtIP has been proven in facilitating end resection in homologous recombination (HR). This study aimed to investigate the role of CtIP in non-homologous end joining (NHEJ) formation. MATERIALS AND METHODS In this study CtIP deficient U87 cell line was generated by using CRISPR/Cas9 method. HR and NHEJ reporter assay were conducted in U87 cells. The cell viability of U87 cells was evaluated by using Sulforhodamine B (SRB) assay. Ionizing radiation assay and clonogenic survival assay were also conducted in this study. Bacteria expressed CtIP and ligase IV proteins were collected and purified. Affinity capture assay was conducted to observe the interactions between proteins. RESULTS Both of the temozolomide (TMZ)-resistant and CtIP deficient glioma cell lines were successfully generated. The results indicated that CtIP participated in NHEJ formation through interacting with ligase IV in glioma cells. CtIP significantly improved the NHEJ efficiency in glioma cells. The CtIP deficient glioma cells were sensitive to the treatment of DNA damaging drug (TMZ). Meanwhile, the CtIP deficiency significantly enhanced the sensitivity of glioma cells to the treatment of TMZ. CONCLUSIONS The present study indicated that CtIP contributed to NHEJ formation through interacting with IV and promotion of TMZ resistance in glioma cells via promoting DSBR efficiency.

Abstract
OBJECTIVE The present study was aimed at illustrating short- or long-term patient outcome among individuals with urgent-start peritoneal dialysis (PD) compared with those with conventional PD. MATERIALS AND METHODS We searched the PubMed, EMBASE, Cochrane Controlled Trials Register and China National Knowledge Infrastructure databases. Cohort studies were investigated comparing the effects of urgent start of PD (<14 days after catheter insertion) to those of conventional start of PD (≥14 days after catheter insertion). Risks of bias across studies were evaluated using Newcastle-Ottawa Quality Assessment Scale. We calculated the pooled risk ratios and mean differences with 95% confidence intervals for dichotomous data and continuous data, respectively. RESULTS Six studies involving 1,242 patients were identified. Compared with conventional PD, urgent-start PD was not associated with a high mortality (RR: 1.25, 95% CI: 0.92 to 1.69; I2=0%, p=0.99) and a higher prevalence of overall mechanical complications (RR: 1.79, 95% CI: 0.85 to 3.78; p=0.12; I2=64%, p=0.02). However, urgent-start PD was associated with a higher prevalence of leakage (RR: 6.72, 95% CI: 2.11 to 21.32; I2=0%, p=0.60). In terms of infectious complications, data analysis of the fixed-effects model showed no difference between the two groups. (RR: 1.36, 95% CI: 0.90 to 2.05, p=0.14), regardless of peritonitis (RR: 1.36, 95% CI: 0.90 to 2.05, p=0.14; I2=0%, p=0.70) or other infections (RR: 1.15, 95% CI: 0.49 to 2.69, p=0.99; I2=0%, p=0.75). CONCLUSIONS Urgent-start PD was not associated with a higher risk of mortality and dialysis-related complications. However, compared with conventional PD, an urgent start of PD may increase the risk of a leak.

Abstract
Objective: To investigate the effect of intestinal preparation on the efficacy and complications of fecal microbiota transplantation (FMT). Methods: A retrospective cohort study was performed. Clinical and follow-up data of 1501 patients who received FMT in the department of Colorectal Disease Specialty, Intestinal Microecology Diagnosis and Treatment Center, the Tenth People's Hospital, Tongji University from February 2018 to June 2019 were collected retrospectively. According to the intestinal preparation before FMT treatment, patients were divided into non-intestinal preparation group (n=216), antibiotic pretreatment group (n=383), intestinal cleansing group (n=267), and antibiotic combined with intestinal cleansing group (n=635). The adverse reactions after FMT treatment and the effective rates at 4-week and 8-week after treatment among the groups were compared. Patients, who repeated FMT treatment in the 3rd month and the 6th month due to reduced efficacy or ineffectiveness were divided into two subgroups: without intestinal preparation group and with intestinal preparation group. The effective rates of the two subgroups were compared. Results: Of the 1501 cases, 588 were male and 913 were female with mean age of (43.3±13.7) years and body mass index of (20.2±2.1) kg/m(2). Transplantation course was (3.3±1.7) weeks. The underlying diseases mainly included constipation (n=564), Crohn's disease (n=157), ulcerative colitis (n=142), irritable bowel syndrome (n=158), recurrent C. difficile infection (CDI) (n=106), autism (n=84), radiation intestinal injury (n=133), radiation enteritis (n=133), and non-CDI chronic diarrhea (n=60); the remaining cases (n=155). Baseline data among the 4 groups were not significantly different (all P>0.05). The overall morbidity of complication was 31.1% (467/1501), including 41 cases of vomiting (2.7%), 91 of nausea (6.1%), 49 of diarrhea (3.3%), 41 of abdominal pain (2.7%), 79 of bloating (5.3%), 72 of throat pain (4.8%), 38 of dizziness (2.5%), 51 of fever (3.4%), 3 of pulmonary infection (0.2%) and 2 of intestinal infection (0.1%). The above symptoms disappeared after symptomatic treatment. There was no statistically significant difference in the incidence of adverse reactions among the 4 groups (P>0.05). After 4-week of FMT treatment, the overall effective rate was 63.5% (902/1420); the effective rate of non-intestinal preparation group, antibiotic pretreatment group, intestinal cleaning group, and antibiotic combined with intestinal cleansing groupwas 57.6% (114/198), 64.2% (231/360), 60.2% (154/265) and 66.5% (403/606), respectively, with no statistically significant difference (χ(2)=6.659, P=0.084). After 8-week of FMT treatment, the overall effective rate was 61.3% (729/1293); the effective rate of non-intestinal preparation group, antibiotic pretreatment group, intestinal cleaning group, and antibiotic combined with intestinal cleansing group was 54.0% (88/163), 62.2% (202/325), 57.4% (132/230) and 64.4% (370/575), respectively, with no statistically significant difference (χ(2)=13.620, P=0.003). The effective rates of antibiotic combined with intestinal cleansing group and antibiotic pretreatment group were obviously higher than that of non-intestinal preparation group (χ(2)=5.789, P=0.016; χ(2)=10.117, P=0.001). Subgroup analysis showed that in the third month, the effective rate at 4-week after treatment was 60.1% (184/306) in the without intestinal preparation group and 61.5% (115/187) in the with intestinal preparation group, whose difference was not significant (χ(2)=0.091, P=0.763); however, in the sixth month, the effective rate at 4-week after treatment was 51.4% (89/173) in the without intestinal preparation group and 61.2% (161/263) in the with intestinal preparationgroup, whose difference was significant (χ(2)=4.229, P=0.040). Conclusions: FMT treatment is safe and effective. The combination of antibiotics and intestinal cleaning can improve overall efficacy of FMT. For patients who need repeated FMT treatment, the combination of antibiotics and intestinal cleaning program within 3 months has no significant effect on the effective rate, but in the sixth month, combinedpreparation is necessary.

Abstract
Objective: To examine the association between the clinical efficacy of fecal microbiota transplantation (FMT) in recipients and the choice of donor, and to observe the characteristics of intestinal flora and metabolites among different donors. Methods: A retrospective case-control study was conducted. Donor whose feces was administrated for more than 30 recipients was enrolled. Data of 20 FMT donors and corresponding recipients at Intestinal Microecology Diagnosis and Treatment Center of the Tenth People's Hospital from October 2018 to December 2019 were collected retrospectively. During follow-up, the efficacy of each recipient 8-week after FMT treatment was recorded and analyzed. Based on the efficacy of each donor, the donors were divided into three groups: high efficacy group (effective rate >60%, 10 donors), moderate efficacy group (effective rate 30%-60%, 6 donors) and low efficacy group (effective rate <30%, 4 donors). The structure of the bacterial flora and the content of fecal short-chain fatty acids in each group of donors were detected and compared among groups. Association of the efficacy of each donor group with the morbidity of complications, and association of efficacy of recipients with donors were analyzed. The evaluation indicators of FMT efficacy included objective clinical effectiveness and/or subjective effectiveness. Objective effectiveness indicated clinical cure plus clinical improvement, and subjective effectiveness indicated marked effectiveness plus medium effectiveness through questionnaire during follow-up. Results: A total of 1387 recipients were treated by 20 donors, including 749 cases of chronic constipation, 141 cases of chronic diarrhea, 107 cases of inflammatory bowel disease (IBD), 121 cases of irritable bowel syndrome (IBS), 83 cases of autism, and 186 cases of other diseases, such as radiation bowel injury, intestinal pseudo-obstruction, paralytic intestinal obstruction, functional bloating and allergic diseases. There were 829 cases, 403 cases, and 155 cases in high efficacy group, moderate efficacy group and low efficacy group respectively. Baseline data among 3 groups were not significantly different (all P> 0.05). In comparison of bacterial abundance (operational taxonomic unit, OTU) among different effective donor groups, the high efficacy group was the highest (330.68±57.28), the moderate efficacy group was the second (237.79±41.89), and the low efficacy group was the lowest (160.60±49.61), whose difference was statistically significant (F=16.910, P<0.001). In comparison of bacterial diversity (Shannon index), the high efficacy group and the moderate efficacy group were higher (2.96±0.36 and 2.67±0.54, respectively), and the low efficacy group was lower (2.09±0.55), whose difference was statistically significant (F=5.255, P=0.017). In comparison of butyric acid content among three groups, the high efficacy group had the highest [(59.20±9.00) μmol/g], followed by middle efficacy group [(46.92±9.48) μmol/g], and the low efficacy group had the lowest [(37.23±5.03) μmol/g], whose difference was statistically significant (F=10.383, P=0.001). The differences of acetic acid and propionic acid among three groups were not statistically significant (all P>0.05). A total of 418 cases developed complications (30.1%). Morbidity of complication in low efficacy group, moderate efficacy group and high efficacy group was 40.6% (63/155), 30.0% (121/403) and 28.2% (243/829) respectively, and the difference was statistically significant (χ(2)=9.568, P=0.008). The incidence of diarrhea in low efficacy group, moderate efficacy group and high efficacy group was 7.1% (11/155), 4.0% (16/403) and 2.8% (23/829) respectively, and the difference was statistically significant (χ(2)=7.239, P=0.027). Comparing the incidences of other types of complications, no statistically significant differences were found (all P>0.05). Follow up began 8 weeks after the FMT treatment. The total follow-up rate was 83.6% (1160/1387). The overall effective rate 58.3% (676/1160). Effective rates of various diseases were as follows: chronic constipation 54.3% (328/604), chronic diarrhea 88.5% (115/130), IBD 56.1% (55/98), IBS 55.1% (59/107), autism 61.6% (45/73), and other diseases 50.0% (74/148). Comparing the effective rate of three groups of donors for different diseases, there was no statistically significant difference in chronic diarrhea (P>0.05); there was a positive correlation trend in IBD, IBS and autism, but the differences were not statistically significant (all P>0.05). For chronic constipation and other diseases, high efficacy group had the highest effective rate [65.0% (243/374) and 63.2% (55/87)], followed by moderate efficacy group [49.4% (86/174) and 38.1% (16/42)], and low efficacy group had the lowest [16.1% (9/56) and 15.8% (3/19)], whose differences were significant (all P<0.05). Conclusions: Different donors have different efficacy in different diseases. Chronic constipation, radiation bowel injury, etc. need to choose donors with high efficacy. IBD, IBS and autism may also be related to the effectiveness of donors, while chronic diarrhea is not associated to the donor. The efficiency of the donor is negatively correlated to the morbidity of complications. The abundance and diversity of intestinal flora and the content of butyric acid may affect the efficacy of the donor.

Abstract
Objective: To evaluate the efficacy and safety of the fecal microbiota transplantation (FMT) in the different route administration for slow transit constipation (STC). Methods: A retrospective cohort study was conducted. The clinical data of 270 STC patients who voluntarily received FMT treatment in the Tenth People's Hospital of Tongji University from May 2018 to May 2019 were collected. Non-relative healthy adult standard donors were applied. The treatment routes of bacterial flora transplantation included nasojejunal tube (nasal enteral tube group, 120 cases), oral enterobacterial capsule treatment (oral capsule group, 120 cases), and colonoscopy infusion (colonoscopy group, 30 cases). The efficacy and safety of treatment among the three groups were compared. Results: Transplanted bacteria of three groups were extracted from 100 g of fresh feces. All the patients successfully completed the transplantation. The waiting time for the nasal enteral tube group, oral capsule group and colonoscopy group was (1.5±0.5) d, (0.4±0.3) d and (3.6±0.8) d respectively; the cost of establishing the transplantation path was (495±20) yuan, (25±10) yuan and (1420±45) yuan respectively, whose differences were statistically significant (F=9.210, P=0.03; F=10.600,P=0.01). The clinical improvement rates at 1 month after FMT treatment in the nasojejunal tube group, oral capsule group and colonoscopy group were 74.2% (89/120), 60.0% (72/120) and 53.3% (16/30) respectively, whose difference was statistically significant (χ(2)=5.990, P<0.05). The clinical improvement rates at 3 months after treatment were 71.1% (69/97), 53.6% (45/84), and 44.0% (11/25) respectively, whose difference was statistically significant (χ(2)=7.620, P<0.05). The incidence of adverse reactions in the colonoscopy group was 76.7% (23/30), which was higher than that in the nasal nasojejunal group (39.2%, 47/120) and oral capsule group (21.7%, 26/120). The most common adverse reactions in the nasojejunal tube group, oral capsule group and colonoscopy group were respiratory discomfort (17.5%, 21/120), nausea and vomiting (10.0%, 12/120), and diarrhea (36.7%, 11/30). During the 3-month follow-up after treatment, no FMT-related adverse reactions were reported. Conclusions: The nasojejunal tube route has stable clinical efficacy and operability, while the oral capsule route has shorter waiting time and less cost. However, the adverse reactions caused by different transplantation methods are different, thus personalized transplantation method should be recommended.

Abstract
The EGFR-targeting cancer therapies are commonly facing drug resistance, mostly due to mutations. Gene therapy with artificial microRNA targeting EGFR conserved sequence may avoid such problem. In this study, we constructed a recombinant adenovirus expressing EGFR-targeting artificial microRNA and active revCASP3 (Ad-EC), under the control of tumor-specific SLPI promoter, and evaluated its inhibitory effect on HEP-2 cancer cells both in vitro and in vivo. MTT assay showed that cell growth inhibition rate at 72h was 44.0% in Ad-EC group at MOI 50, while the rate was 7.7% in the control virus Ad-GFP group and 3.6% in Cetuximab (500 μg/ml) group respectively. Flow cytometry analysis revealed the late apoptotic cells rate was 36.1% in Ad-EC group, significantly higher than 6.5% of Ad-GFP group (p < 0.001). When Ad-EC (MOI 50) was combined with CDDP (0.25 μg/ml), late apoptotic cells rate increased to 61.2%, significantly higher than each monotherapy group (P < 0.001). The real-time xCELLigence system recorded an effective cell growth inhibition in Ad-EC and CDDP groups, and more enhanced effect in Ad-EC plus CDDP group. Western blot revealed that Ad-EC could inhibit the activation of AKT pathway and ERK1/2 pathway, while Cetuximab had the AKT pathway over-activated. In vivo experiments with HEP-2 xenograft in nude mice confirmed the tumor inhibition in Ad-EC, CDDP and Ad-EC plus CDDP groups compared with PBS group (P < 0.01). Collectively, these data support the effective inhibition of cancer cells by this novel gene therapy strategy.

Abstract
The in vitro detection of low abundance biomolecules via nonenzymatic signal amplification is an attractive strategy. However, it remains a challenge to monitor targets of interest in situ in living cells by low-background interference and visualized enzyme-free signal amplification strategies. Taking advantage of the single-molecule imaging and dynamic DNA nanotechnologies, we have achieved the target-triggered self-assembly of nanostructure-based dual-color fluorescent probes (NDFPs) by an enzyme-free toehold-mediated strand displacement cascade. NDFPs will facilitate the simple and visualized monitoring of microRNA (miRNA) at the femtomolar level. The recycled miRNA can be considered as the catalyst for the assembly of multiple H1/H2 duplexes. This generated the fluorescence signal of the enhanced target expression, indicating both in vitro and in vivo signal-amplified imaging. Moreover, the NDFPs improved the measurement accuracy by dual-color colocalization imaging to greatly avoid false-positive signals and enabled the successful in situ imaging of miRNA in living cells in real time. This work provides a strategy to visually monitor and study the integration of signal amplification detection and single-molecule imaging. NDFPs may be an important step toward the enzyme-free amplified monitoring and imaging of various biomolecules in living cells at the single-molecule level.

Abstract
BACKGROUND Our previous study showed that convoluted cerebriform pattern (CCP)-based reverse tracing method in preoperative magnetic resonance imaging (MRI) is a reliable tool in predicting originating site of sinonasal inverted papilloma (SNIP). This study aimed to determine the underlying pathological mechanism of the preoperative MRI-CCP reverse tracing method by assessing the histopathological changes from the origin to the peripheral sites of SNIP. METHODOLOGY The originating site of SNIP was predicted by preoperative MRI in 30 consecutive patients suspected to have primary SNIP. Samples of SNIP originating and peripheral sites were processed by pathological staining for evaluation of stroma score, micro-vessel density (MVD), and tight junction proteins (claudin-5, zonula occludens (ZO)-1 and occludin) expression. RESULTS The originating site of SNIP was accurately predicted by preoperative MRI in all patients. Stroma scores, and MVD were significantly greater in the periphery of SNIP than in the originating site. In contrast, Claudin-5 expression in micro-vessels was greater at the originating site than the periphery. CONCLUSIONS More edematous stroma and intensive micro-vessels with defective tight junction in periphery of SNIP result in more contrast agent diffusing and CCP that can only be observed at the periphery of SNIP on T2 and contrast-enhanced T1 weighted MR images, which may be the mechanisms underlying the CCP reverse tracing method.

Abstract
Secondary caries caused by dental plaque is one of the major reasons for the high failure rate of resin composite restoration. Although antimicrobial agent-modified dental restoration systems have been researched for years, few reported intelligent anticaries materials could respond to the change of the oral environment and help keep oral eubiosis. Herein, we report tertiary amine (TA)-modified resin adhesives (TA@RAs) with pH-responsive antibacterial effect to reduce the occurrence of secondary caries. Two kinds of newly designed TA monomers were synthesized: DMAEM (dodecylmethylaminoethyl methacrylate) and HMAEM (hexadecylmethylaminoethyl methacrylate). In the minimum inhibitory concentration and minimum bactericidal concentration test against Streptococcus mutans, Streptococcus sanguinis, and Streptococcus gordonii, they exhibited antibacterial effect only in acidic medium, which preliminarily verified the acid-activated effect of TAs. Then DMAEM and HMAEM were incorporated into adhesive resin at the mass fraction of 5%, yielding TA@RAs. In vivo and in vitro tests showed that the mechanical properties and biocompatibility of the adhesive were not affected. A S. mutans biofilm model in acidic and neutral medium was used and confirmed that TA@RAs could respond to the critical pH value of de-/remineralization and acquire reversible antibiofilm effect via the protonation and deprotonation of TAs. Meanwhile, the stability of antibacterial effect was confirmed via a 5-d pH-cycling experiment and a saliva-derived biofilm aging model. Furthermore, 16S rRNA gene sequencing showed that TA@RAs could increase the diversity of the saliva-derived biofilms, which implied that the novel materials could help regulate the microbial community to a healthy one. Finally, an in vitro demineralization model and in vivo secondary caries model were applied and demonstrated that TA@RAs could prevent secondary dental caries effectively. In summary, the reversible pH-responsive and non-drug release antibacterial resin adhesives ingeniously overcome the defect of the present materials and hold great promise for clinical application.

Abstract
Aims Preoperative diagnosis is important for revision surgery after prosthetic joint infection (PJI). The purpose of our study was to determine whether reverse transcription-quantitative polymerase chain reaction (RT-qPCR), which is used to detect bacterial ribosomal RNA (rRNA) preoperatively, can reveal PJI in low volumes of aspirated fluid. Methods We acquired joint fluid samples (JFSs) by preoperative aspiration from patients who were suspected of having a PJI and failed arthroplasty; patients with preoperative JFS volumes less than 5 ml were enrolled. RNA-based polymerase chain reaction (PCR) and bacterial culture were performed, and diagnostic efficiency was compared between the two methods.According to established Musculoskeletal Infection Society (MSIS) criteria, 21 of the 33 included patients were diagnosed with PJI. Results RNA-based PCR exhibited 57.1% sensitivity, 91.7% specificity, 69.7% accuracy, 92.3% positive predictive value, and 55.0% negative predictive value. The corresponding values for culture were 28.6%, 83.3%, 48.5%, 75.0%, and 40.0%, respectively. A significantly higher sensitivity was thus obtained with the PCR method versus the culture method. Conclusion In situations in which only a small JFS volume can be acquired, RNA-based PCR analysis increases the utility of preoperative puncture for patients who require revision surgery due to suspected PJI.

Abstract
Background:Rheumatoid arthritis (RA) is an autoimmune disease that mainly invades synovial membranes and further damage to articular cartilage and bone. The abnormal activation of transforming-growth factor β (TGF-β) in the subchondral bone is related to the onset of RA joint cartilage degeneration and transforming-growth interacting factor (TGIF) is a negative regulator of TGF-β signaling, while there is no literature addressing the relationship between TGIF polymorphisms and the bone metabolism of RA.Objectives:The aim of the study was to comprehensively explore the possible association for single nucleotide polymorphisms (SNPs) in the TGIF gene with serum bone metabolism markers and RA susceptibility.Methods:Three SNPs within the TGIF gene were genotyped in 155 RA patients and 168 healthy controls by high resolution melting (HRM) analysis in a case-control study. The serum levels of osteocalcin, bone alkaline phosphatase (BALP) and β type I collagen-crosslinked C telopeptide (β-CTX) were detected by electrochemical luminescence in 108 RA patients randomly selected from RA patients group.Results:Genotypes and alleles frequency analysis showed rs7362020 was associated with bone erosion in RA (P=0.012, P=0.003, respectively) and individuals carrying T allele for rs7362020 showed a decreased RA risk (OR=0.59, 95% CI = 0.42-0.84; P= 0.003). In the gender-specific analysis, rs73620203 polymorphism was associated with bone erosion of female RA patients (P values of the distribution of genotypes and alleles were 0.022 and 0.006, respectively). In addition, RA patients with CC, CT and TT genotypes at rs73620203 locus had statistically significant differences in serum osteocalcin and BALP (P=0.006, P=0.037, respectively) and the serum levels in TT genotype RA patients were significantly lower than CC and CT genotype RA patients. The serum levels of β-CTX in rs85440 AA genotype male RA patients were significantly higher than female RA patients (P=0.001), while the serum levels of osteocalcin and BALP in genotype AA, AG and GG female and male RA patients were not significantly different (P all>0.05).Conclusion:Our study provided the first evidence that rs73620203 is associated with bone erosion of RA and provided new insight into the relationship between three SNPs within TGIF gene and regulation of bone metabolism in RA patients of different genders.Acknowledgments:This work was supported by the National Natural Science Foundation of China (Nos. 81772258) and Science and Technology Agency of Sichuan Province (Nos. 2019YFS0310, 2018FZ0106).Disclosure of Interests:None declared

Abstract
BACKGROUND Accurate preoperative prediction of the malignant transformation of sinonasal inverted papilloma (SNIP) is essential for radical resection of tumours and prevention of recurrence. We here explored the predictive value of preoperative computed tomography (CT) and magnetic resonance imaging (MRI). METHODOLOGY The study was performed on 268 patients with SNIP with (n = 78) or without (n = 190) coexistent malignant transformation. We used univariate and multivariate logistic regression analysis method to screen for independent risk factors, and established a nomogram model. Finally, using receiver operating characteristic curves, we assessed the diagnostic value of the independent risk factors for malignant transformation of SNIP. RESULTS We identified bone erosion on CT, change in convoluted cerebriform pattern (CCP) on MRI, and washout-type time intensity curve (TIC) of dynamic contrast-enhanced (DCE)-MRI were independent predictors of malignant transformation of SNIP. The scores of these three independent risk factors from the nomogram model were 10, 7 and 8, respectively. The area under the receiver operating characteristic curve for predicting SNIP malignancy was 0.954 for the nomogram model, 0.826 for bone erosion, 0.776 for washout-type TIC, and 0.810 for CCP mutation. CONCLUSIONS Of the independent risk factors and related combination identified, the nomogram model based on bone destruction on CT, CCP mutation on MRI, and washout-type TIC of DCE-MRI had the best predictive value for malignant transformation of SNIP.

Understanding how sediment transport and storage will delay, attenuate, and even erase the erosional signal of tectonic and climatic forcings has bearing on our ability to read and interpret the geologic record effectively. Here, we estimate sediment transit times in Australia's largest river system, the Murray-Darling basin, by measuring downstream changes in cosmogenic 26Al/10Be/14C ratios in modern river sediment. Results show that the sediments have experienced multiple episodes of burial and reexposure, with cumulative lag times exceeding 1 Ma in the downstream reaches of the Murray and Darling rivers. Combined with low sediment supply rates and old sediment blanketing the landscape, we posit that sediment recycling in the Murray-Darling is an important and ongoing process that will substantially delay and alter signals of external environmental forcing transmitted from the sediment's hinterland.

Abstract
e12569 Background: Breast cancer (BC) is one of the most common malignant tumors among women in the world. Although under 7% of all BC cases, young BC is more difficult to diagnose and can be aggressive and less likely to respond to treatment. Exploring and identifying potential biomarkers for the diagnosis and prognosis of younger BC patients is necessary. Methods: A total of 1,202 BC patients under 35 years old (YD) were enrolled. Deep sequencing targeting 450 cancer genes was performed in a laboratory accredited by College of American Pathologists (CAP) and certified by Clinical Laboratory Improvement Amendments (CLIA) for genomic alteration identification. Statistical analysis was performed by Fisher’s exact test. Results: Of 1,202 young BC patients, 3 were under 20 YD, 85 were 20-25 YD, 371 were 26-30 YD, and 747 were 31-35 YD. Based on pathological, there were 899 infiltrative duct carcinomas, 10 infiltrative lobular carcinomas, and 292 BCs with unclear pathological type. According to molecular features, 587 HR+/HER2- (group I), 118 HR+/HER2+ (group II), 75 HR-/HER2+ (group III) and 193 HR-/HER2- (group IV) were included. Chemotherapy, radiotherapy, endocrine therapy and targeted therapy were received and 1074 patients were followed up. The median overall survival (OS) was 76 (5-156) months. There was no significant difference in OS between different treatments. The median OS was 81 (range 5-156) months, 67 (range 10-153) months, 76 (range 14-146) months, and 78 (range 13-151) months for group I, II, III, and IV, respectively. The significantly lower OS was observed in group II ( P=0.044). Although group II and group III had similar proportion of targeted treatment (43.22% vs 43.24%, respectively), the OS rate was different (67 vs 76 months, P=0.064). Samples from 46 young BC patients were performed on deep sequencing targeting 450 cancer genes. The most common mutations were TP53 (56%), GATA3 (29%), ERBB2 (27%), CDK12 (20%), and FGFR1 (20%). Different from previous studies, only 4.35% (2/46) of BRCA1/2 mutations were detected in this cohort. The mutation frequency of GATA3 in group II was significantly lower than that in group III (0% vs 71.43%, P=0.017). Conclusions: The most common pathological type of young BC was infiltrative duct carcinoma. The OS of HR+/HER2+ patients were significantly lower than that of others. Our results showed that GATA3 could be a potential biomarker for OS prediction for BC with HER2+, which help to further guide targeted therapy in young BC patients.

Abstract
An inelastic excitation and cluster-decay experiment ^{2}H(^{16}C,^{4}He+^{12}Be or ^{6}He+^{10}Be)^{2}H was carried out to investigate the linear-chain clustering structure in neutron-rich ^{16}C. For the first time, decay paths from the ^{16}C resonances to various states of the final nuclei were determined, thanks to the well-resolved Q-value spectra obtained from the threefold coincident measurement. The close-threshold resonance at 16.5 MeV is assigned as the J^{π}=0^{+} band head of the predicted positive-parity linear-chain molecular band with (3/2_{π}^{-})^{2}(1/2_{σ}^{-})^{2} configuration, according to the associated angular correlation and decay analysis. Other members of this band were found at 17.3, 19.4, and 21.6 MeV based on their selective decay properties, being consistent with the theoretical predictions. Another intriguing high-lying state was observed at 27.2 MeV which decays almost exclusively to ^{6}He+^{10}Be(∼6 MeV) final channel, corresponding well to another predicted linear-chain structure with the pure σ-bond configuration.

Abstract
The racial disparity of facial features in craniosynostosis patients is not fully understood. The aim of this study was to explore the difference in maxillary and mandibular morphology and spatial position in Asian and Caucasian Crouzon syndrome patients. Ninety-one computed tomography scans were included (12 Asian Crouzon syndrome patients, 22 Asian controls; 16 Caucasian Crouzon syndrome patients, 41 Caucasian controls) and measured using Materialise software. The maxillary and mandibular volumes of Asian patients were both reduced by 19% (P=0.102 and P=0.187), and those of Caucasian patients were reduced by 15% (P=0.142) and 14% (P=0.211) when compared to the respective race-specific controls. Maxilla length of Asian patients was reduced by 6.36mm (14%, P=0.003), while the reduction in Caucasian patients was 4.88mm (10%, P=0.038). ANS was retracted 11.99mm (P<0.001) in Asian patients and 11.54mm (P<0.001) in Caucasian patients. The ANB angle was narrowed by 13.17° (P<0.001) in Asian patients compared to Asian controls, and by 7.02° (P<0.001) in Caucasian patients compared to Caucasian controls. The retrusive midface profiles of Asian and Caucasian Crouzon syndrome look similar; both result from the combined effect of hypoplastic size and backward displacement. However, the insufficiency was found to be more a failure of the anteroposterior maxillary length in Asian patients, and more due to posterior maxillary positioning in Caucasian patients. Therefore, prognathism in Crouzon syndrome patients is more likely caused by displacement rather than elongation of mandibular length in both races. Crouzon syndrome results in the same extent of overall volume deficiency of the maxilla and mandible in these races.

Abstract
Pullorum disease caused by Salmonella Pullorum is one of the most important infectious diseases in the poultry industry worldwide, which leads to serious economic losses in many developing countries because of its high mortality rate in young chicks. The traditional slide agglutination test with low cost, fast reaction, and on-site detection has been widely used in the diagnosis of Pullorum disease. However, in practice, the test performance is with the disadvantages of false positive results and unstable detection results. In this paper, we developed self-made agglutination antigens prepared by local isolates in the poultry farm and compare the detection performance with commercial agglutination antigens (China Institute of Veterinary Drug Control) and Group D Salmonella ELISA kit (BioChek UK Ltd). The results of detecting 200 serum samples indicated that the consistency of commercial agglutination antigen detecting in 2 times was only 79.5%. Using the ELISA kit as the reference method, the commercial agglutination antigen detecting results of the Kappa test were only moderately consistent (0.58 ∼ 0.59). Meanwhile, positive and total coincidence rates of the self-made agglutination antigen test with more reliable repeat could reach 97.4 and 88%, respectively, and the result of Kappa test was highly consistent (0.75). The Receiver Operating Characteristic curve analysis clarified that the area under the receiver-operating-characteristic curve values of self-made and commercial agglutination antigen tests could reach 0.861 and 0.804, respectively. These results were coincident when detecting known positive serum from the infected chickens. It's worth mentioning that the visible positive reaction of self-made agglutination antigen test appeared faster and stronger than commercial antigen test. In conclusion, self-made Salmonella Pullorum agglutination antigen developed in this study was much better than commercial agglutination antigen and is expected to be a valuable tool in the diagnosis of the epidemiology of Salmonella Pullorum.

Abstract
Permafrost and methane hydrates are large, climate-sensitive old carbon reservoirs that have the potential to emit large quantities of methane, a potent greenhouse gas, as the Earth continues to warm. We present ice core isotopic measurements of methane (Δ14C, δ13C, and δD) from the last deglaciation, which is a partial analog for modern warming. Our results show that methane emissions from old carbon reservoirs in response to deglacial warming were small (<19 teragrams of methane per year, 95% confidence interval) and argue against similar methane emissions in response to future warming. Our results also indicate that methane emissions from biomass burning in the pre-Industrial Holocene were 22 to 56 teragrams of methane per year (95% confidence interval), which is comparable to today.

Abstract
Objective: To investigate the superficial and internal adaptations of a new self-curing composite resin in Class Ⅴ cavities. Methods: Class Ⅴ cavities were prepared in 56 caries-free human maxillary premolars (collected from Department of Oral and Maxillofacial Surgery, Capital Medical University School of Stomatology) extracted for orthodontic reasons, and these premolars were assigned into two groups (28 specimens each group). Experimental group were restored with a pretreating agent (Tooth primer) and a new self-curing composite resin (Bondfill SB). Control group were restored with a self-etching adhesive (Scotchbond Universal) and a light-curing composite resin (Z100). The restored teeth were subjected to a fatigue test to simulate temperature change and occlusal load in oral environment: mechanical cycles (1 200 000 cycles at 49 N with a frequency of 1 Hz) and thermocycles (3 000 cycles from 5 ℃ to 55 ℃ with a dwelling time of 1 min each). Before and after fatigue test, restored teeth were immersed in an 50% ammoniacal silver nitrate solution and reduced. Superficial perfect margin percentage value and length of silver deposit along the internal interface were quantified by scanning electron microscopy (SEM). Ultrastructure of dentin bonding interface was analyzed by transmission electron microscope (TEM). Results: Before fatigue test, superficial gaps at dentin side in the specimens in experimental group were narrower than those in control group, and length of silver deposit at enamel side [(0.67±0.15) μm] in specimens in the control group was significantly lower than that in the experimental group [(33.54± 10.27) μm] (P<0.05). After the fatigue test, control group showed higher perfect margin percentage value to enamel [(55.08±15.20)%] than experimental group [(25.15±12.47)%] did (P<0.05). After the fatigue test, cohesive failures could be more easily found in experimental group than in control group at surficial and internal interfaces. In TEM results, more silver deposits were found at dentin bonding interface in control group than in experimental group before the fatigue test. After the fatigue test, the deterioration at dentin bonding interface mostly happened at the bottom of the hybrid layer in control group, while in experimental group it could be found at the bottom of the hybrid layer and in the restorative material. Conclusions: When restored in Class Ⅴ cavity, the studied light-curing composite shows better superficial and internal adaptations for enamel than the new self-curing composite resin and the new self-curing composite resin shows good superficial and internal adaptations for dentin.

Abstract
OBJECTIVE Recent studies have revealed that long noncoding RNAs (lncRNAs) play important roles in the progression of tumorigenesis. Oral squamous cell carcinoma is a disease widely widespread all over the world. The aim of this study was to identify how lncRNA INHBA-AS1 functions in the progression of OSCC. PATIENTS AND METHODS LncRNA INHBA-AS1 expression in both OSCC cells and 48 paired tissue samples was detected by Real Time-quantitative Polymerase Chain Reaction (RT-qPCR). The function of INHBA-AS1 was identified by the transwell assay, wound healing assay, and proliferation assay in vitro. Meanwhile, the role of INHBA-AS1 was investigated through tumor formation assay in vivo. Furthermore, the underlying mechanism was explored by the luciferase assays and RNA immunoprecipitation assay (RIP). RESULTS INHBA-AS1 was highly expressed in OSCC tissues when compared with adjacent tissue samples. The proliferation, invasion, and migration of OSCC cells were significantly inhibited after the knockdown of INHBA-AS1 in vitro. Meanwhile, the knockdown of INHBA-AS1 remarkably inhibited tumor growth and metastasis in vivo. Besides, miR-143-3p was down-regulated after the knockdown of INHBA-AS1 in vitro. The expression of miR-143-3p was negatively correlated with the expression of INHBA-AS1 in OSCC tissues. In addition, miR-143-3p was directly targeted by INHBA-AS1. CONCLUSIONS The knockdown of INHBA-AS1 repressed cell migration, invasion, and proliferation in OSCC by sponging miR-143-3p, which might offer a new therapeutic intervention for OSCC patients.

Abstract
Objective: To explore the feasibility, safety and long-term efficacy of laparoscopic total gastrectomy combined with distal pancreaticosplenectomy for the treatment of T4b gastric cancer. Methods: A retrospective cohort study was performed. Clinical data of consecutive patients with T4b gastric cancer invading pancreatic tail undergoing laparoscopic or open total gastrectomy combined with distal pancreaticosplenectomy from January 2010 to December 2014 were analyzed retrospectively. Enrollment criteria: (1) primary gastric cancer confirmed by pathology as T4b adenocarcinoma; (2) chest+abdominal+pelvic enhanced CT indicated cancer invading pancreatic tail without distant metastasis, and R0 resection was evaluated as feasible before operation; (3) physical status was ECOG score 0 to 2, and was tolerant to operation. Patients with peritoneal implant metastasis and tumor invasion of other organs during operation, or changes in surgical methods for other reasons were excluded. All the operations were performed by the same surgical team, which had the experiences of more than 100 cases of laparoscopic and 100 cases of open radical gastrectomy with D2 lymph node dissection. The choice of surgical procedure was discussed by the surgeon and the patient, and decided according to the patient's intension. Patients were divided into the laparoscopic group and open group according to the surgical method. Intraoperative and perioperative findings were compared between the two groups. The 3-year disease-free survival rate were analyzed with Kaplan-Meier survival curve and compared by using log-rank test. Results: A total of 37 consecutive patients were enrolled, including 21 in the laparoscopic group and 16 in the open group, and no one receiving laparoscopic procedure was converted to open surgery. The baseline data of two groups were comparable (all P>0.05). Compared with the open group, the laparoscopic group had significantly longer operation time [(264.0±35.1) minutes vs. (226.6±49.9) minutes, t=2.685, P=0.011], significantly less intraoperative blood loss [(65.7±37.4) ml vs. (182.2±94.6) ml, t=-4.658, P<0.001], significantly shorter time to postoperative flatus [(2.8±0.7) days vs. (4.1±0.7) days, t=-5.776, P<0.001] and significantly shorter postoperative hospital stay [(13.3±2.8) days vs. (16.6±4.3) days, t=-2.822, P=0.008]. Morbidity of postoperative complications, including anastomotic leakage, pancreatic fistula, abdominal abscess, intraperitoneal hemorrhage and duodenal stump leakage, in two groups was similar [19.0% (4/21) vs. 4/16, P=0.705]. There were no cases of anastomotic bleeding or stenosis. The 30-day postoperative mortality was 0 in the laparoscopic group and 1/16 in the open group, respectively (P=0.432). The 3-year disease-free survival rates were 38.1% and 37.5% in the laparoscopic and open group, respectively (P=0.751). Conclusion: Laparoscopic total gastrectomy combined with distal pancreaticosplenectomy performed by experienced surgeons for T4b gastric cancer is safe and effective.

Abstract
Objective: To investgate the effect of properative transitional zone index (TZI) on the outcome of transurethral resection of prostate (TURP). Methods: A retrospective analysis was performed on 206 patients with TURP who were admitted to our hospital from January 2016 to September 2018. All patients underwent transrectal ultrasound (TRUS) to determine the total prostate volume (TPV) and the transition zone volume (TZV). Patients were divided into two groups according to TZI (TZV/TPV) (group A: TZI<0.5, group B: TZI≥0.5). We collected data 6-months after surgery including international prostate symptom score (IPSS), quality of life score (QOL), maximum flow rate (Qmax), and postvoiding residue (PVR) to compare the difference of the postoperative outcome of two groups, while the IPSS was subdivided into voiding (IPSS-v) and storage(IPSS-s) symptoms, and the changes of IPSS, IPSS-v, IPSS-s, QOL, Qmax and PVR before and after surgery were analyzed. The treatment efficacy was determined as the changes of IPSS (post/preoperative IPSS: %IPSS), QOL (preoperative QOL-postoperative QOL: ΔQOL) and Qmax(preoperative Qmax-postoperative Qmax: ΔQmax). Pearson linear correlation analysis was employed to estimate the correlation of TZI and %IPSS, ΔQOL and ΔQmax, respectively. Results: A total of 126 patients were in Group A, and 80 patients were in group B. 1. The preoperative clinical data of the two groups were compared. There were no significant differences regarding age, IPSS, IPSS-v, IPSS-s, QOL, Qmax, and PVR between two groups (all P>0.05). However, the TPV of patients in group B (74.57±29.25) ml was significantly larger than that in group A (46.25±24.56) ml, P<0.001. While the postoperative follow-up outcomes of the two groups were compared, we found that IPSS-s (P=0.079), QOL (P=0.710), and PVR (P=0.651) were not statistically different between the two groups, but the postoperative IPSS, IPSS-v, and Qmax (8.50±5.75 vs 6.38±4.36, 4.03±3.75 vs 2.63±2.5, and (16.54±4.43) ml/s vs (18.94±4.84) ml/s, all P<0.05) were significantly different between the two groups. 2. Postoperative IPSS, IPSS-v, IPSS-s, QOL, Qmax and PVR were significantly different from those before surgery in two groups, respectively. 3. Pearson linear correlation analysis showed a significant positive correlation between TZI and ΔQmax (r=0.32, P<0.01), a weaker negative correlation between TZI and %IPSS (r=-0.22, P<0.01), and no correlation between TZI and ΔQOL (r=0.08, P=0.238). Conclusion: There may be a correlation between the outcome of TURP and TZI, and the outcome of TURP may be better in patients with TZI ≥ 0.5.

Abstract
BACKGROUND Although massive studies have been conducted to investigate the mechanisms of esophageal squamous cell carcinoma (ESCC) carcinogenesis, the understanding of molecular alterations during the malignant transformation of epithelial dysplasia is still lacking, especially regarding epigenetic changes. RESULTS To better characterize the methylation changes during the malignant transformation of epithelial dysplasia, a whole-genome bisulfite sequencing analysis was performed on a series of tumor, dysplastic, and non-neoplastic epithelial tissue samples from esophageal squamous cell carcinoma (ESCC) patients. Promoter hypermethylation in TGF-β receptor type II (TGFBR2), an important mediator of TGF-β signaling, was identified. Further, we evaluated the methylation and expression of TGFBR2 in tumor samples through The Cancer Genome Atlas multiplatform data as well as immunohistochemistry. Moreover, treatment of ESCC cell lines with5-Aza-2'-deoxycytidine, a DNA methyltransferase inhibitor, reactivated the expression of TGFBR2. The lentiviral mediating the overexpression of TGFBR2 inhibited the proliferation of ESCC cell line by inducing cell cycle G2/M arrest. Furthermore, the overexpression of TGFBR2 inhibited the tumor growth obviously in vivo. CONCLUSIONS The characterization of methylation silencing of TGFBR2 in ESCC will enable us to further explore whether this epigenetic change could be considered as a predictor of malignant transformation in esophageal epithelial dysplasia and whether use of a TGFBR2 agonist may lead to a new therapeutic strategy in patients with ESCC.

Abstract
It was well-known that Berberine, a major bioactive compound extracted from natural plants Coptis chinensis, has anti-diabetic effects for decades in china. Other types of pharmacological activities, such as anti-inflammatory, antimicrobial, hypolipidemic, and anti-cancer effects, have also been examined. At cellular level, these pharmacological activities were mostly an inhibitory effect. However, the cytoprotective effect of berberine was also observed in various types of cells, such as neurons, endothelial cells, fibroblasts, and β-cells. The paradoxical result may be closely associated with characteristics and distribution of berberine within cells, and they can be explained mechanically by mitohormesis, one particular form of hormesis. Here, we reviewed the mitohormetic response and assessed the berberine-induced effects and the possible signaling pathway involved. These findings may contribute to better clinical applications of berberine and indicate that some mitochondria-targeted conventional drugs should be considered carefully in clinical application.
