Abstract
OBJECTIVE QL1604 is a highly selective, humanized monoclonal antibody against programmed death protein 1. We assessed the efficacy and safety of QL1604 plus chemotherapy as first-line treatment in patients with advanced cervical cancer. METHODS This was a multicenter, open-label, single-arm, phase II study. Patients with advanced cervical cancer and not previously treated with systemic chemotherapy were enrolled to receive QL1604 plus paclitaxel and cisplatin/carboplatin on day 1 of each 21-day cycle for up to 6 cycles, followed by QL1604 maintenance treatment. RESULTS Forty-six patients were enrolled and the median follow-up duration was 16.5 months. An 84.8% of patients had recurrent disease and 13.0% had stage IVB disease. The objective response rate (ORR) per Response Evaluation Criteria in Advanced Solid Tumors (RECIST) v1.1 was 58.7% (27/46). The immune ORR per immune RECIST was 60.9% (28/46). The median duration of response was 9.6 months (95% confidence interval [CI]=5.5-not estimable). The median progression-free survival was 8.1 months (95% CI=5.7-14.0). Forty-five (97.8%) patients experienced treatment-related adverse events (TRAEs). The most common grade≥3 TRAEs (>30%) were neutrophil count decrease (50.0%), anemia (32.6%), and white blood cell count decrease (30.4%). CONCLUSION QL1604 plus paclitaxel-cisplatin/carboplatin showed promising antitumor activity and manageable safety profile as first-line treatment in patients with advanced cervical cancer. Programmed cell death protein 1 inhibitor plus chemotherapy may be a potential treatment option for the patient population who have contraindications or can't tolerate bevacizumab, which needs to be further verified in phase III confirmatory study. Trial RegistrationClinicalTrials.gov Identifier: NCT04864782.

Abstract
BACKGROUND Endometrial-derived stem cells are key players in endometriosis (EMs) pathogenesis, while the mechanism involved is still unclear. Herein, the role and regulatory mechanism of endometriotic mesenchymal stem cells (ecto-MSCs) in regulating fibrosis during EMs progression were investigated. METHODS The mRNA and protein expressions were assessed using qRT-PCR, western blot, and immunofluorescence. Flow cytometry was adopted to analyze the markers of MSCs. Transwell assay was adopted to examine endometriotic stromal cells (ESCs) migration and invasion. The interactions between DNMT3A and RASAL1 were analyzed by ChIP assay. In addition, MSP was employed to detect RASAL1 promoter methylation level. RESULTS Ecto-MSCs promoted ESCs migration, invasion, and fibrosis process by TGF-β1 paracrine. It was subsequently revealed that TGF-β1 upregulated DNMT3A in ESCs in a SMAD3-dependent manner. As expected, DNMT3A knockdown abolished ecto-MSCs' facilitation on ESCs migration, invasion, and fibrosis process. DNMT3A, as a methyltransferase, reduced RASAL1 expression in TGF-β1-treated ESCs by increasing RASAL1 promoter methylation level. RASAL1, as an antifibrotic protein, was lowly expressed in TGF-β1-treated ESCs, and its overexpression ameliorated TGF-β1-induced increase in ESCs migration, invasion, and fibrosis process. CONCLUSION TGF-β1 secreted by ecto-MSCs facilitated fibrogenesis in EMs through SMAD3/DNMT3A-mediated RASAL1 inhibition.

Abstract
PURPOSE/OBJECTIVE(S) The CREST study showed that the addition of thoracic radiotherapy (TRT) could improve the survival of extensive stage small cell lung cancer (ES-SCLC), but whether TRT can bring survival benefit in the era of immunotherapy is controversial. This study aims to explore the efficacy and safety of adding TRT to the combination of PD-L1 inhibitors and chemotherapy. MATERIALS/METHODS Thepatients who received PD-L1 inhibitors combined with platinum-based chemotherapy as the first-line treatment of ES-SCLC from January 2019 to December 2021 were retrospectively collected. According to whether they received TRT, they were divided into two groups, and the follow-up analysis was performed. Propensity score matching (PSM) in with a 1:1 ratio was performed to balance the baseline characteristics of the two cohorts. The endpoints were progression-free survival (PFS) and OS. RESULTS A total of 211 patients with ES-SCLC were enrolled, of whom 70 (33.2%) patients received standard therapy plus TRT as first-line treatment, and 141 (66.8%) patients in the control group received PD-L1 inhibitors plus chemotherapy. After PSM, a total of 65 pairs of patients were enrolled in the analysis. There were no significant differences in baseline characteristics between the two groups of patients who received TRT and those who did not. In all patients, the median PFS (mPFS) in the TRT group and the non-TRT groupwere 9.5 months and 7.2 months, respectively, with HR = 0.60 (95% CI 0.41-0.87, p = 0.007). The median OS (mOS) in the TRT group was also significantly longer than that in the non-TRT group (24.1 months vs. 18.5 months, HR = 0.53, 95% CI 0.32-0.85, p = 0.009). Multivariable analysis showed that baseline liver metastasis and bone metastasis were independent prognostic factors for OS. In terms of safety, immunotherapy combined with thoracic radiotherapy increased the incidence of treatment-related pneumonia (p<0.001), most of which were grade 1-2. CONCLUSION This real-world study shows that adding TRT to durvalumab or atezolizumab plus chemotherapy significantly improves survival in ES-SCLC. It leads to more treatment-related pneumonia, but most of them can be relieved after symptomatic treatment. This treatment model deserves to be explored in prospective clinical trials.

Abstract
Epithelial ovarian cancer (EOC) is a fatal gynecological malignancy with limited therapeutic options. Previous research has demonstrated that Tripterygium glycosides (GTW) can enhance effectiveness of cisplatin (DDP) chemotherapy against EOC. However, the underlying mechanism of GTW alleviating EOC still remains unclear. In this article, an ID8 cell-derived xenograft mouse model was established to evaluate the anti-tumor efficacy of GTW combined with DDP. Consistent with previous findings, the results suggested that GTW combined with DDP can exhibit a stronger tumor suppressive effect than DDP alone. Additionally, GTW was found can further exert gastrointestinal protection against DDP by reducing pathological damage on colon tissue. Secondly, to verify whether gut microbiota play an instrumental role in GTW's anticancer effect, we treated mice models with antibiotic to eliminate gut microbiota. And our experimental results indicated that all drug groups showed a weaker tumor suppressive effect and more severe gastrointestinal damage post antibiotic supplement. At genus level, the relative abundance of Lactobacillus was dramatically diminished by the antibiotic treatment, while combined treatment of GTW and DDP can significantly restore the level. Moreover, we performed Lactobacillus acidophilus transplantation and healthy mice fecal microbiota transplantation experiments to further investigate the link between the anticancer effect of GTW and gut microbiota. Our results suggested that both cisplatin-sensitizing and intestinal barrier-protecting effects of GTW can be recovered to a different extent. In conclusion, our results indicated that GTW is a promising chemosensitization and intestinal barrier repair drug for EOC, and the potential mechanism may corelate with the restoration of the compromised intestinal microbial balance.

Abstract
Objective: Cancer immunotherapy can lead to various side effects, termed immune-related adverse events (irAE). This study summarized and analyzed the clinical and pathological characteristics of immune-mediated liver injury caused by immune checkpoint inhibitors (ILICI). Methods: This is a retrospective case series study involving 11 patients diagnosed with ILICI at the Peking Union Medical College Hospital from November 2019 to November 2021. Patient demographic information and clinical data, including gender, age, ILICI onset, clinical and radiological manifestations, pathological features, treatment, and resumption of ICI were retrospectively collected and analyzed. Results: The patients were primarily males (9/11) with a median age of 65 (range: 32-73) years. ICI mainly resulted in either partial remission (4/11) or stable disease (3/11). ILICI occurred after a median of two cycles of anti-programmed cell death-1 (PD-1) therapy, with a median time from the initial and last anti-PD-1 therapy to ILICI onset of 57 days and 17 days, respectively. ILICI was mostly severe (3/11) or very severe (6/11). While the clinical and radiological manifestations were non-specific, the pathological features were active lobular hepatitis and portal inflammation, with prominent CD8+T lymphocyte infiltration. The basic treatment was hepatoprotective drugs (10/11). Glucocorticoids were used as the primary therapy (9/11) but were ineffective in 4 of 9 cases. Of these, 3 of 9 cases received combined treatment with mycophenolate mofetil (MMF), only one of whom achieved remission. By the end of the study, 2 of 11 cases had resumed ICI and neither had experienced an ILICI relapse. Conclusion: The ILICI patients in this study had a corresponding history of ICI treatment and pathological features. The main treatment included hepatoprotective drugs and glucocorticoids. Immunosuppressive drugs were added for some cases but had poor efficacy.

Abstract
Cisplatin resistance is the main cause of postoperative recurrence and difficulty in the treatment of ovarian cancer. It is urgently needed to identify therapeutic drugs with unique functions to overcome the current challenges in the treatment of ovarian cancer. In this study, we found that TG promoted the accumulation of ROS and MDA in A2780/DDP cells and downregulated the expression of key antioxidant molecules. In vivo, the survival rate of tumor-bearing nude mice was prolonged by TG without significant hepatotoxic reaction. The expression of key antioxidant molecules in tumor tissues was consistent with that in vitro. These findings revealed that TG disrupted homeostasis of redox reactions and induced ferroptosis in A2780/DDP cells, thereby enhancing cisplatin chemosensitivity of ovarian cancer. Overall, TG may be a novel potential therapeutic option for reversing resistance to cisplatin chemotherapy.

Abstract
BACKGROUND Endometriosis is a severe disease which is associated with excessive activation of pyroptosis. Our present research aimed to investigate the function of Forkhead Box A2 (FoxA2) in regulating pyroptosis in endometriosis. METHODS IL-1β and IL-18 concentrations were assessed using ELISA. Cell pyroptosis was analyzed using flow cytometry. TUNEL staining was performed to determine human endometrial stromal cells (HESC) death. Moreover, ERβ mRNA stability was assessed using RNA degradation assay. Finally, the binding relationships between FoxA2, IGF2BP1 and ERβ were verified by dual-luciferase reporter system, ChIP, RIP and RNA pull-down assays. RESULTS Our results revealed that IGF2BP1 and ERβ were significantly upregulated in ectopic endometrium (EC) tissues of endometriosis patients compared to that in eutopic endometrium (EU) tissues as well as IL-18 and IL-1β levels. Loss-of-function experiments subsequently demonstrated that either IGF2BP1 knockdown or ERβ knockdown could repress HESC pyroptosis. In addition, IGF2BP1 upregulation promoted the pyroptosis in endometriosis by binding to ERβ and promoting ERβ mRNA stability. Our further research displayed that FoxA2 upregulation suppressed HESC pyroptosis by interacting with IGF2BP1 promoter. CONCLUSION Our research proved that FoxA2 upregulation downregulated ERβ by transcriptionally inhibiting IGF2BP1, thereby repressing pyroptosis in endometriosis.

Abstract
Consumption of commercial probiotics for health improvement and disease treatment has increased in popularity among the public in recent years. The local shops and pharmacies are brimming with various probiotic products such as probiotic food, dietary supplement and pharmaceuticals that herald a range of health benefits, from nutraceutical benefits to pharmaceutical effects. However, although the probiotic market is expanding rapidly, there is increasing evidence challenging it. Emerging insights from microbiome research and public health demonstrate several potential limitations of the natural properties, regulatory frameworks, and market consequences of commercial probiotics. In this review, we highlight the potential safety and performance issues of the natural properties of commercial probiotics, from the genetic level to trait characteristics and probiotic properties and further to the probiotic-host interaction. Besides, the diverse regulatory frameworks and confusing probiotic guidelines worldwide have led to product consequences such as pathogenic contamination, overstated claims, inaccurate labeling and counterfeit trademarks for probiotic products. Here, we propose a plethora of available methods and strategies related to strain selection and modification, safety and efficacy assessment, and some recommendations for regulatory agencies to address these limitations to guarantee sustainability and progress in the probiotic industry and improve long-term public health and development.

Objective: To explore the diagnostic value of different serological markers and the correlation with disease phenotype in inflammatory bowel disease (IBD). Methods: The clinical data of 445 IBD patients in Peking Union Medical College Hospital from June 2010 to December 2020 were retrospectively collected, including 223 cases of ulcerative colitis (UC) [111 males, 112 females, with a median age of 46(20,79) years] and 222 cases of Crohn's disease (CD) [147 males, 75 females, with a median age of 39 (19, 72) years]. The positive rates of serum anti-neutrophil cytoplasmic antibodies (ANCA), anti-Saccharomyces cerevisiae antibodies (ASCA), goblet cell autoantibodies (GAB) and pancreatic autoantibodies (PAB) in the two groups were analyzed. The sensitivity, specificity, positive predictive value and negative predictive value of UC and CD were calculated. Logistic regression was performed to analyze the relationship between different combinations of antibodies and disease phenotype. Results: The positive rates of ASCA and PAB in CD patients were 34.7% (77/222) and 38.3% (85/222), respectively, which were higher than those in UC patients [10.3% (23/223) and 4.5% (10/223), P<0.001]. The positive rate of ANCA in UC patients was 50.2% (112/223), which was higher than that in CD patients [5.4% (12/222), P<0.001]. The positive rates of serum GAB in CD and UC patients were 21.6% (48/222) and 28.3% (63/223), respectively, with no significant difference (P=0.760). In patients with CD, the sensitivity of mono-marker ASCA (+), dual-marker ASCA (+) ANCA (-), quadruple-marker ASCA (+) ANCA (-) PAB (+) GAB (-) in diagnosing CD was 34.7%, 32.9%, 20.7%, the specificity was 89.7%, 95.5%, 100.0%, the positive predictive value was 77.0%, 90.1%, 100.0%, and the negative predictive value was 58.0%, 58.7%, 55.9%, respectively. In patients with UC, the sensitivity of mono-marker ANCA (+), dual-marker ANCA (+) ASCA (-), quadruple-marker ANCA (+) ASCA (-) PAB (-) GAB (+) in diagnosing UC was 50.2%, 40.4%, 24.2%, the specificity was 94.6%, 95.5%, 100.0%, the positive predictive value was 90.3%, 90.0%, 100.0%, and the negative predictive value was 65.4%, 61.4%, 56.8%, respectively. Mono-marker ASCA (+) (OR=3.39, 95%CI: 1.59-7.21), dual-marker ASCA (+) ANCA (-) (OR=2.87, 95%CI: 1.34-6.14), triple-marker ASCA (+) ANCA (-) GAB (-) (OR=3.09, 95%CI: 1.31-7.31) and quadruple-marker ASCA (+) ANCA (-) PAB (+) GAB (-) (OR=3.15, 95%CI: 1.56-8.03) were associated with stenosis and/or penetrating type CD. The mono-marker ANCA (+) (OR=2.69, 95%CI: 1.42-5.12) and dual-marker ANCA (+) ASCA (-) (OR=2.11, 95%CI: 1.03-4.16) were associated with extensive colonic lesions in UC. Conclusion: Based on ASCA or ANCA, the combination with PAB or GAB, is conducive to IBD diagnosis, and is associated with stenosis and/or penetrating type of CD and extensive type of UC.

Abstract
This study aimed to evaluate the effect in female rats of 6 weeks of ginger consumption on gestational diabetes by assessing glucose and lipid metabolism, oxidative damage, inflammation, and the WNT/β-catenin/glycogen synthase kinase-3 beta (GSK3β) signaling pathway. In this study, 40 adult female rats were divided into 4 equal groups as follows: pregnant rats, pregnant rats with diabetes, pregnant rats consuming ginger, and pregnant rats with diabetes consuming ginger. Induction of diabetes on day 0 of pregnancy was induced by streptozotocin (STZ) injection. Insulin, glucose, and lipid profiles as metabolic factors were measured along with the hepatic expression of glucose transporter type 4 (GLUT4), mechanistic target of rapamycin complex 1 (mTORc1), sterol regulatory element-binding protein-1c (SREBP-1c), peroxisome proliferator-activated receptor α (PPAR-α), β-catenin, GSK3β, PPAR-g, nuclear factor-κB (NF-kB), and nuclear factor erythroid 2-related factor 2 (Nrf2). The levels of tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), and oxidative parameters were measured in the liver. The level of metabolic factors was significantly impaired in diabetic pregnant rats compared to the control group. However, ginger improved these parameters in the diabetic pregnant—ginger group compared to the diabetic pregnant group. The hepatic expression of genes involved in metabolism, oxidative stress, inflammation, and the wingless and int-1 (WNT) signaling pathway was significantly impaired in diabetic pregnant rats, while ginger improved them in the hepatic tissue of diabetic pregnant rats. It can be concluded that ginger could improve gestational diabetes by genes involved in metabolism, the WNT signaling pathway, oxidative stress, and inflammation. These results suggest that ginger can be an adjunct drug during pregnancy as a metabolic modulator.

Abstract
Objective: To identify the related factors and characteristics of gut microbiota and metabolites in inflammatory bowel disease (IBD) patients with urolithiasis. Methods: A total of 68 IBD patients with urolithiasis and 136 gender-and age-matched IBD patients without urolithiasis in the Department of Gastroenterology, Peking Union Medical College Hospital from January 2014 to December 2019 were recruited. The diagnosis of urolithiasis was confirmed by plain films, ultrasonography, abdominal computed tomography or intravenous urography. The clinical data of patients were collected, and the association between the clinical characteristics and urolithiasis was further analyzed. The fecal samples were collected from 10 patients with urolithiasis and 18 patients without urolithiasis, and the gut microbiota and metabolites composition were analyzed. Results: There were 49 male and 19 female IBD patients with urolithiasis, with a mean age of (36.0±12.4) years, and 98 male and 38 female patients without urolithiasis, with a mean age of (36.1±12.5) years. Univariate analysis revealed that the rate of ileostomy and the resection of small intestine in Crohn's disease (CD) patients with urolithiasis (n=34) was significantly higher than CD patients without urolithiasis (n=68) (26.5% vs 7.4%, P=0.019). And the erythrocyte sedimentation rate was also higher [26.5 (12.0, 40.8) vs 13.0 (7.2, 32.5) mm/1 h, P=0.022] in CD patients with urolithiasis. There were no significant differences in clinical characteristics and biochemical parameters between the ulcerative colitis (UC) patients with urolithiasis (n=34) and without urolithiasis (n=68) (all P>0.05). The multivariate logistic regression analysis indicated that ileostomy and the resection of small intestine were the independent related factors for urolithiasis in CD patients (OR=4.619, 95%CI: 1.178-18.111, P=0.028). There was no significant difference in α and β diversity between the two groups (all P>0.05). At the phylum level, there was no significant difference in the abundance of microbiota (all P>0.05). At the genus level, the abundance of Enterococcus (P=0.049), Eubacterium_eligens (P=0.036) was significantly decreased. At the species level, the abundance of Bacteroides_coprocola was increased in urolithiasis group (P=0.035), while the abundance of Blautia_caecimuris was significantly decreased (P=0.042). No significant difference was found in fecal metabolites between the two groups (all P>0.05). According to LDA effect size (Lefse) analysis, taxa including Sphingomonadales, Fenollaria, Bacteroides_coprocola contributed greatly to the difference between the two groups. Conclusions: Ileostomy and the resection of small intestine are related factors for urolithiasis in patients with CD. Gut microbiota may be involved in the occurrence of urolithiasis in patients with IBD.

Abstract
BACKGROUND The optimal anastomotic techniques in esophagectomy to minimize rates of anastomotic leakage and conduit necrosis are not known. The aim of this study was to assess whether the anastomotic technique was associated with anastomotic failure after esophagectomy in the international Oesophago-Gastric Anastomosis Audit cohort. METHODS This prospective observational multicenter cohort study included patients undergoing esophagectomy for esophageal cancer over 9 months during 2018. The primary exposure was the anastomotic technique, classified as handsewn, linear stapled, or circular stapled. The primary outcome was anastomotic failure, namely a composite of anastomotic leakage and conduit necrosis, as defined by the Esophageal Complications Consensus Group. Multivariable logistic regression modeling was used to identify the association between anastomotic techniques and anastomotic failure, after adjustment for confounders. RESULTS Of the 2238 esophagectomies, the anastomosis was handsewn in 27.1%, linear stapled in 21.0%, and circular stapled in 51.9%. Anastomotic techniques differed significantly by the anastomosis sites (P < .001), with the majority of neck anastomoses being handsewn (69.9%), whereas most chest anastomoses were stapled (66.3% circular stapled and 19.3% linear stapled). Rates of anastomotic failure differed significantly among the anastomotic techniques (P < .001), from 19.3% in handsewn anastomoses, to 14.0% in linear stapled anastomoses, and 12.1% in circular stapled anastomoses. This effect remained significant after adjustment for confounding factors on multivariable analysis, with an odds ratio of 0.63 (95% CI, 0.46-0.86; P = .004) for circular stapled versus handsewn anastomosis. However, subgroup analysis by anastomosis site suggested that this effect was predominantly present in neck anastomoses, with anastomotic failure rates of 23.2% versus 14.6% versus 5.9% for handsewn versus linear stapled anastomoses versus circular stapled neck anastomoses, compared with 13.7% versus 13.8% versus 12.2% for chest anastomoses. CONCLUSIONS Handsewn anastomoses appear to be independently associated with higher rates of anastomotic failure compared with stapled anastomoses. However, this effect seems to be largely confined to neck anastomoses, with minimal differences between techniques observed for chest anastomoses. Further research into standardization of anastomotic approach and techniques may further improve outcomes.

Abstract
Die perkutane hepatische Chemosaturation ist eine Behandlungsoption bei nichtresektablen primären oder sekundären Lebertumoren. Dabei wird der Bereich der Lebervenenmündung der Vena cava inferior (VCI) mittels 2 Ballons von der Zirkulation isoliert, sodass die systemische Verteilung des über die Leberarterie applizierten Chemotherapeutikums Melphalan verhindert wird. Nach Passage der Leber und venöser Drainage aus der retrohepatischen VCI durchläuft das chemosaturierte Blut 2 parallel geschaltete extrakorporale Filter. Anschließend wird das gereinigte Blut jugulär rückgeführt. Das Verfahren geht oft mit einer ausgeprägten hämodynamischen Instabilität einher, deren Ursache nicht abschließend geklärt ist. Zusätzlich stellt das Gerinnungsmanagement eine Herausforderung dar. Die Autoren berichten von einem Fall, bei dem sich trotz ausreichender „activated clotting time“ (ACT) ein Thrombus im rückführenden Schenkel der extrakorporalen Zirkulation bildete. Gezielte Problemsuche und -lösung waren parallel zur hämodynamischen Stabilisierung und interdisziplinären Zusammenarbeit notwendig, um die Intervention erfolgreich durchzuführen und der Patientin eine sichere Therapie zukommen zu lassen.

Abstract
Abstract
Background
Textbook outcome has been proposed as a tool for the assessment of oncological surgical care. However, an international assessment in patients undergoing oesophagectomy for oesophageal cancer has not been reported. This study aimed to assess textbook outcome in an international setting.
Methods
Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018 to December 2018. Textbook outcome was defined as the percentage of patients who underwent a complete tumour resection with at least 15 lymph nodes in the resected specimen and an uneventful postoperative course, without hospital readmission. A multivariable binary logistic regression model was used to identify factors independently associated with textbook outcome, and results are presented as odds ratio (OR) and 95 per cent confidence intervals (95 per cent c.i.).
Results
Of 2159 patients with oesophageal cancer, 39.7 per cent achieved a textbook outcome. The outcome parameter ‘no major postoperative complication’ had the greatest negative impact on a textbook outcome for patients with oesophageal cancer, compared to other textbook outcome parameters. Multivariable analysis identified male gender and increasing Charlson comorbidity index with a significantly lower likelihood of textbook outcome. Presence of 24-hour on-call rota for oesophageal surgeons (OR 2.05, 95 per cent c.i. 1.30 to 3.22; P = 0.002) and radiology (OR 1.54, 95 per cent c.i. 1.05 to 2.24; P = 0.027), total minimally invasive oesophagectomies (OR 1.63, 95 per cent c.i. 1.27 to 2.08; P < 0.001), and chest anastomosis above azygous (OR 2.17, 95 per cent c.i. 1.58 to 2.98; P < 0.001) were independently associated with a significantly increased likelihood of textbook outcome.
Conclusion
Textbook outcome is achieved in less than 40 per cent of patients having oesophagectomy for cancer. Improvements in centralization, hospital resources, access to minimal access surgery, and adoption of newer techniques for improving lymph node yield could improve textbook outcome.

Abstract
Endometriosis (EMS) is a disease characterized by estrogen-dependent, chronic inflammatory, and annoying symptoms, which inflicts about 10% reproductive-age women. The diagnosis of endometriosis mainly depends on pathological examination after surgical resection while the pathogenesis of EMS is not clear enough. Surgical resection and drug therapy (including painkillers and hormone therapy, especially gonadotropin-releasing hormone analogs, GnRH-a) are widely used, but they are expensive and have many side effects. There are few studies on vaginal microorganisms in women with endometriosis. We collected vaginal secretions from women with EMS confirmed by pathology and demonstrated that they were different from that of healthy women by 16s rRNA high-throughput sequencing. Additionally, we established the EMS model in female mice by intraperitoneally injecting fragments from donor mice (3-week growth). Then, the mice were treated with mixed antibiotics (vagina) and NF-κB signaling pathway inhibitors (intraperitoneal injection), respectively. The result suggested that the ectopic lesions were inhibited. In addition, inflammatory cytokines IL-1β, IL-6, and TNF-α in peritoneal fluid, cell proliferation marker ki-67, and macrophage marker Iba-1 in ectopic lesions decreased significantly from that of mock mice. We also observed similar results as above by vaginal microbiota transplantation (VMT) and subcutaneous injection of leuprorelin acetate (LA, one of GnRH-a) for mice with EMS. These results showed that vaginal use of antibiotics or VMT is helpful to treat endometriosis in mice. However, due to the great difference between human and mouse vaginal microbiota, its mechanism and clinical transformation application still need to be further studied in the future.

Abstract
The side-effects of therapeutic drugs and the intrinsic or acquired cisplation resistance are considered impediments in the clinic treatment of human epithelial ovarian cancer, which contribute heavily to the startlingly high mortality. It is imperative to look for drugs to inhibit cancer and minimize the chemotherapy resistance safely and effectively from the Chinese herbal medicine. In the present study, we evaluated the anti-cancer effect of Tripterygium glycosides (GTW) and its sensitizing effect with cisplation (DDP) both in vitro and in vivo. The 5-ethynyl-2'-deoxyuridine (EdU) proliferation assay, transwell assay, and scratch wound healing assay demonstrated that GTW and DDP+GTW prominently inhibited the proliferation, migration, and invasion of SKOV3/DDP cells. In addition, treatment using GTW and DDP+GTW for 24 h significantly decreased the expression of ILK, p-AKT, p-GSK3β, N-Cadherin, and Slug, and markedly enhanced the expression of E-cadherin. Moreover, animal results confirmed that GTW and DDP+GTW significantly inhibited the tumor volume, increased the apoptosis of tumors cells and reduced the production of tumor markers CA125 and HE4 in mice serum. Similar to the results in vitro, GTW and DDP+GTW significantly inhibited the expression of proteins in epithelial-mesenchymal transition (EMT) and ILK/GSK3β/Slug signal pathway in tumors in vivo. In conclusion, our results indicated that GTW may be served as a potential therapeutic drug combination with DDP to treat drug resistant ovarian cancer via regulating ILK/GSK3β/Slug signal pathway.

Abstract
Rett syndrome may be treated by reactivating the silent copy of Mecp2 from the inactive X chromosome in female cells. Most studies that model Mecp2 reactivation have used mouse fibroblasts rather than neural cells, which would be critical for phenotypic reversal, and rely on fluorescent reporters that lack adequate sensitivity. Here, we present a mouse model based on a dual bioluminescent and fluorescent reporter to assess the level of reactivation of Mecp2 and the inactive X chromosome by treating neural stem cells with 5-azacytidine and Xist knockdown. We show that reactivation of Mecp2 and other X-linked genes correlates with CpG density, with distance from escapees, and, very strongly, with the presence of short interspersed nuclear elements. In addition, X-linked genes reactivated in neural stem cells overlap substantially with early reactivating genes by induced pluripotent stem cell reprogramming of fibroblasts or neuronal progenitors, indicating that X chromosome reactivation follows similar paths regardless of the technique or cell type used.

Abstract
Abstract
Background
Delirium is associated with increased morbidity and mortality in the older person and still remains poorly detected. The Health Service Executive (HSE) has clear algorithms and guidelines which suggest that any person over the age of 65, especially so for patients with pre-existing dementia, presenting to the Emergency Department (ED) or Acute Medical Assessment Unit (AMAU) should be screened for delirium using the 4AT test. An earlier retrospective audit carried out by the authors in the same hospital showed that only 9% of patients with diagnosed delirium had a 4AT test at any point during inpatient stay and 0% had one on admission. We designed a prospective audit to assess what proportion of patients over 65 coming through the Acute Medical Assessment Unit (AMAU) had a delirium screening test performed on admission.
Methods
We reviewed the admission notes of all patients over 65 admitted through the AMAU over a continuous 14 day period from 10/11/20 to 24/11/2020. The admission notes were reviewed within 24 hours of admission. Exclusion criteria included patients presenting delirium tremens and patients presenting with a stroke.
Results
119 patients were identified. The mean age was 78.1 years. 20 (16.8%) had previously diagnosed dementia. 0 patients had a delirium screening test conducted by AMAU/ED staff on admission. 2 (1.7%) had 4AT tests done by members of the Geriatric Emergency Medical Services (GEMS) team within 24 hours. The GEMS team only sees patients who fulfill certain criteria on admission. 10 (8.4%) had ‘delirium’ listed on their differential diagnoses.
Conclusion
Our results show that the older patient being admitted through the AMAU in this hospital in Ireland is not being adequately screened for delirium. Additionally, even when delirium was suspected, delirium screening tools were not being implemented for further assessment. More needs to be done to ensure patients over 65 are assessed as per guidelines.

Abstract
BACKGROUND The complexity of oesophageal surgery and the significant risk of morbidity necessitates that oesophagectomy is predominantly performed by a consultant surgeon, or a senior trainee under their supervision. The aim of this study was to determine the impact of trainee involvement in oesophagectomy on postoperative outcomes in an international multicentre setting. METHODS Data from the multicentre Oesophago-Gastric Anastomosis Study Group (OGAA) cohort study were analysed, which comprised prospectively collected data from patients undergoing oesophagectomy for oesophageal cancer between April 2018 and December 2018. Procedures were grouped by the level of trainee involvement, and univariable and multivariable analyses were performed to compare patient outcomes across groups. RESULTS Of 2232 oesophagectomies from 137 centres in 41 countries, trainees were involved in 29.1 per cent of them (n = 650), performing only the abdominal phase in 230, only the chest and/or neck phases in 130, and all phases in 315 procedures. For procedures with a chest anastomosis, those with trainee involvement had similar 90-day mortality, complication and reoperation rates to consultant-performed oesophagectomies (P = 0.451, P = 0.318, and P = 0.382, respectively), while anastomotic leak rates were significantly lower in the trainee groups (P = 0.030). Procedures with a neck anastomosis had equivalent complication, anastomotic leak, and reoperation rates (P = 0.150, P = 0.430, and P = 0.632, respectively) in trainee-involved versus consultant-performed oesophagectomies, with significantly lower 90-day mortality in the trainee groups (P = 0.005). CONCLUSION Trainee involvement was not found to be associated with significantly inferior postoperative outcomes for selected patients undergoing oesophagectomy. The results support continued supervised trainee involvement in oesophageal cancer surgery.

Abstract
In vitro fertilization (IVF) is an important assisted reproductive technology in treating infertility, whose failure rate is still high. Studies suggested that uterine microbiota are related to women’s reproductive diseases and persisting intrauterine bacterial infectious conditions, such as chronic endometritis (CE), impairing the pregnant processes. However, the relationship between uterine microbiota and IVF outcomes is still an open question. In the present study, 94 patients diagnosed with infertility were enrolled and were divided into CE (E group, n = 25) and non-CE (NE group, n = 69) groups depending on the hysteroscopy and immunohistochemistry. Subsequently, E (Ep, n = 8 and Enp, n = 17) and NE (NEp, n = 41 and NEnp, n = 28) groups were divided into pregnancy and non-pregnancy groups depending on the IVF outcomes, respectively. The uterine fluids were collected and microbial profiles were examined through the V4 region of 16S rRNA gene high-throughput sequencing. The results demonstrated that patients with CE had significantly lower clinical pregnancy rate compared with the non-CE patients (32 vs. 58.42%, p = 0.0014). The relative abundances of Proteobacteria and Acidobacteria were higher in the non-CE group, whereas high abundances of Actinobacteria and Fusobacteria were observed in the CE group at the phylum level. At the genus level, high relative abundances of Gardnerella were observed in the CE group and non-pregnancy groups, which significantly referred to the negative IVF outcome. In conclusion, CE may be a key factor for the negative outcome after IVF, of which the uterine microbiota plays a pivotal role, and the microbial diversity in uterine may serve as a biomarker to forecast the success of IVF outcome.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic had caused a severe depletion of the worldwide supply of N95 respirators. The development of methods to effectively decontaminate N95 respirators while maintaining their integrity is crucial for respirator regeneration and reuse. In this study, we systematically evaluated five respirator decontamination methods using vaporized hydrogen peroxide (VHP) or ultraviolet (254 nm wavelength, UVC) radiation. Through testing the bioburden, filtration, fluid resistance, and fit (shape) of the decontaminated respirators, we found that the decontamination methods using BioQuell VHP, custom VHP container, Steris VHP, and Sterrad VHP effectively inactivated Cardiovirus (3-log10 reduction) and bacteria (6-log10 reduction) without compromising the respirator integrity after 2-15 cycles. Hope UVC system was capable of inactivating Cardiovirus (3-log10 reduction) but exhibited relatively poorer bactericidal activity. These methods are capable of decontaminating 10-1000 respirators per batch with varied decontamination times (10-200 min). Our findings show that N95 respirators treated by the previously mentioned decontamination methods are safe and effective for reuse by industry, laboratories, and hospitals.

Abstract
Chemoresistance is the primary reason for the poor prognosis of patients with ovarian cancer, and the search for a novel drug treatment or adjuvant chemotherapy drug is an urgent need. The tumor microenvironment plays key role in the incidence and development of tumors. As one of the most important components of the tumor microenvironment, M2 tumor-associated macrophages are closely related to tumor migration, invasion, immunosuppressive phenotype and drug resistance. Many studies have confirmed that triptolide (TPL), one of the principal components of Tripterygium wilfordii, possesses broad-spectrum anti-tumor activity. The aims of this study were to determine whether TPL could inhibit the migration and invasion of A2780/DDP cells in vitro and in vivo by inhibiting the polarization of M2 tumor-associated macrophages (TAMs); to explore the mechanism(s) underlying TPL effects; and to investigate the influence of TPL on murine intestinal symbiotic microbiota. In vitro results showed that M2 macrophage supernatant slightly promoted the proliferation, invasion, and migration of A2780/DDP cells, which was reversed by TPL in a dose-dependent manner. Animal experiments showed that TPL, particularly TPL + cisplatin (DDP), significantly reduced the tumor burden, prolonged the life span of mice by inhibiting M2 macrophage polarization, and downregulated the levels of CD31 and CD206 (CD31 is the vascular marker and CD206 is the macrophage marker), the mechanism of which may be related to the inhibition of the PI3K/Akt/NF-κB signaling pathway. High-throughput sequencing results of the intestinal microbiota in nude mice illustrated that Akkermansia and Clostridium were upregulated by DDP and TPL respective. We also found that Lactobacillus and Akkermansia were downregulated by DDP combined with TPL. Our results highlight the importance of M2 TAMs in Epithelial Ovarian Cancer (EOC) migration ability, invasiveness, and resistance to DDP. We also preliminarily explored the mechanism governing the reversal of the polarization of M2 macrophages by TPL.

Abstract
BACKGROUND In colon cancer, tumor deposits (TD) are considered in assigning prognosis and staging only in the absence of lymph node metastasis (i.e. stage III pN1c tumors). We aimed to evaluate the prognostic value of the presence and the number of TD in patients with stage III, node-positive colon cancer. PATIENTS AND METHODS All participants from the CALGB/SWOG 80702 phase III trial were included in this post hoc analysis. Pathology reports were reviewed for the presence and the number of TD, lymphovascular and perineural invasion. Associations with disease-free survival (DFS) and overall survival (OS) were evaluated by multivariable Cox models adjusting for sex, treatment arm, T-stage, N-stage, lymphovascular invasion, perineural invasion and lymph node ratio. RESULTS Overall, 2028 patients were included with 524 (26%) TD-positive and 1504 (74%) TD-negative tumors. Of the TD-positive patients, 80 (15.4%) were node negative (i.e. pN1c), 239 (46.1%) were pN1a/b (<4 positive lymph nodes) and 200 (38.5%) were pN2 (≥4 positive lymph nodes). The presence of TD was associated with poorer DFS [adjusted hazard ratio (aHR) = 1.63, 95% CI 1.33-1.98] and OS (aHR = 1.59, 95% CI 1.24-2.04). The negative effect of TD was observed for both pN1a/b and pN2 groups. Among TD-positive patients, the number of TD had a linear negative effect on DFS and OS. Combining TD and the number of lymph node metastases, 104 of 1470 (7.1%) pN1 patients were re-staged as pN2, with worse outcomes than patients confirmed as pN1 (3-year DFS rate: 65.4% versus 80.5%, P = 0.0003; 5-year OS rate: 87.9% versus 69.1%, P = <0.0001). DFS was not different between patients re-staged as pN2 and those initially staged as pN2 (3-year DFS rate: 65.4% versus 62.3%, P = 0.4895). CONCLUSION Combining the number of TD and the number of lymph node metastases improved the prognostication accuracy of tumor-node-metastasis (TNM) staging.

Abstract
BACKGROUND No evidence currently exists characterising global outcomes following major cancer surgery, including esophageal cancer. Therefore, this study aimed to characterise impact of high income countries (HIC) versus low and middle income countries (LMIC) on the outcomes following esophagectomy for esophageal cancer. METHOD This international multi-center prospective study across 137 hospitals in 41 countries included patients who underwent an esophagectomy for esophageal cancer, with 90-day follow-up. The main explanatory variable was country income, defined according to the World Bank Data classification. The primary outcome was 90-day postoperative mortality, and secondary outcomes were composite leaks (anastomotic leak or conduit necrosis) and major complications (Clavien-Dindo Grade III - V). Multivariable generalized estimating equation models were used to produce adjusted odds ratios (ORs) and 95% confidence intervals (CI95%). RESULTS Between April 2018 to December 2018, 2247 patients were included. Patients from HIC were more significantly older, with higher ASA grade, and more advanced tumors. Patients from LMIC had almost three-fold increase in 90-day mortality, compared to HIC (9.4% vs 3.7%, p < 0.001). On adjusted analysis, LMIC were independently associated with higher 90-day mortality (OR: 2.31, CI95%: 1.17-4.55, p = 0.015). However, LMIC were not independently associated with higher rates of anastomotic leaks (OR: 1.06, CI95%: 0.57-1.99, p = 0.9) or major complications (OR: 0.85, CI95%: 0.54-1.32, p = 0.5), compared to HIC. CONCLUSION Resections in LMIC were independently associated with higher 90-day postoperative mortality, likely reflecting a failure to rescue of these patients following esophagectomy, despite similar composite anastomotic leaks and major complication rates to HIC. These findings warrant further research, to identify potential issues and solutions to improve global outcomes following esophagectomy for cancer.

Abstract
BACKGROUND The Esophagectomy Complications Consensus Group (ECCG) and the Dutch Upper Gastrointestinal Cancer Audit (DUCA) have set standards in reporting outcomes after oesophagectomy. Reporting outcomes from selected high-volume centres or centralized national cancer programmes may not, however, be reflective of the true global prevalence of complications. This study aimed to compare complication rates after oesophagectomy from these existing sources with those of an unselected international cohort from the Oesophago-Gastric Anastomosis Audit (OGAA). METHODS The OGAA was a prospective multicentre cohort study coordinated by the West Midlands Research Collaborative, and included patients undergoing oesophagectomy for oesophageal cancer between April and December 2018, with 90 days of follow-up. RESULTS The OGAA study included 2247 oesophagectomies across 137 hospitals in 41 countries. Comparisons with the ECCG and DUCA found differences in baseline demographics between the three cohorts, including age, ASA grade, and rates of chronic pulmonary disease. The OGAA had the lowest rates of neoadjuvant treatment (OGAA 75.1 per cent, ECCG 78.9 per cent, DUCA 93.5 per cent; P < 0.001). DUCA exhibited the highest rates of minimally invasive surgery (OGAA 57.2 per cent, ECCG 47.9 per cent, DUCA 85.8 per cent; P < 0.001). Overall complication rates were similar in the three cohorts (OGAA 63.6 per cent, ECCG 59.0 per cent, DUCA 62.2 per cent), with no statistically significant difference in Clavien-Dindo grades (P = 0.752). However, a significant difference in 30-day mortality was observed, with DUCA reporting the lowest rate (OGAA 3.2 per cent, ECCG 2.4 per cent, DUCA 1.7 per cent; P = 0.013). CONCLUSION Despite differences in rates of co-morbidities, oncological treatment strategies, and access to minimal-access surgery, overall complication rates were similar in the three cohorts.

Abstract
Advanced and recurrent ovarian cancer has a poor prognosis and is frequently resistant to numerous therapeutics; thus, safe and effective drugs are needed to combat this disease. Previous studies have demonstrated that triptolide (TPL) exhibits anticancer and sensitization effects against cisplatin (DDP)-resistant ovarian cancer both in vitro and in vivo by inducing apoptosis; however, the involvement of autophagy induced by TPL in resistant ovarian carcinoma remains unclear. In the present study, the results revealed that TPL induced autophagy to facilitate SKOV3/DDP ovarian cancer cell death. The xenograft experiment revealed that the autophagy inhibitor CQ significantly reduced TPL-mediated chemosensitization and tumor growth inhibition. Mechanically, TPL-induced autophagy in SKOV3/DDP cells was associated with the induction of ROS generation and inhibition of the Janus kinase 2 (JAK2)/signal transducer and activator of transcription-3 (STAT3) pathway. The inhibitory effect of TPL on the JAK2/STAT3 pathway could be restored in the presence of the antioxidant NAC. Furthermore, it was further determined that TPL disrupted the interaction between Mcl-1 and Beclin1, which was prevented by the JAK2/STAT3 signaling activator IL-6. Overall, the present results revealed a novel molecular mechanism whereby TPL induced lethal autophagy through the ROS-JAK2/STAT3 signaling cascade in SKOV3/DDP cells. The present study has provided the groundwork for future application of TPL in the treatment of ovarian cancer.

Abstract
DEC1 has been reported to regulate the expression of multiple target genes, participate in cell differentiation, apoptosis, aging and the development and progression of numerous tumors, but the detailed effects and possible mechanisms of DEC1 in ovarian cancer (OC) remain unknown. The present study aimed to investigate the expression and mechanism of function of DEC1 in OC. The present results demonstrated that DEC1 was highly expressed in OC tissues and cell lines using reverse transcription-quantitative PCR, western blotting and immunohistochemistry, and high expression of DEC1 was negatively associated with the prognosis of patients with OC. In addition, knockdown of DEC1 significantly inhibited proliferation in SKOV3 and OVCAR3 cells compared with control. DEC1 knockdown also induced apoptosis and increased the expression of apoptosis-related proteins in OC cells. The results suggested that knockdown of DEC1 inhibited OC cell migration and invasion via regulation of epithelial-mesenchymal transition-related protein. It was also found that DEC1 knockdown significantly inhibited the Wnt/β-catenin pathway. Collectively, the current results indicated that knockdown of DEC1 inhibited proliferation, migration and invasion, and induced apoptosis in OC cells via modulating the Wnt/β-catenin signaling pathway. Thus, DEC1 may participate in malignant progression of OC, and may be a target for treatment and diagnosis of OC.

Abstract
Objective: To analyze clinical characteristics and monitor microbiome changes in patients with anti-PD-1 associated colitis. Methods: Two patients with non-small cell lung cancer who developed colitis after treated with anti-PD-1 antibodies were retrospectively analyzed in Peking Union Medical College Hospital from January 2019 to January 2020. The clinical symptoms, endoscopic and pathological manifestations, as well microbiome changes were analyzed and compared during pre-treatment, post-treatment and relapse. Results: The main clinical manifestations included diarrhea, elevated inflammatory indicators, colonic mucosal diffuse hyperemic edema with erosion by endoscopy. Changes in the structure of crypts were common pathological characteristics. Glucocorticoids were effective agents, which achieved clinical remission and mucosal healing. The microbiome composition of OTUs was different. After glucocorticoid treatment, the alpha diversity Observed species, Shannon, Simpson, Chao1, ACE indexes all decreased. The Firmicutes decreased with Bacteroidetes increasing in phylum level; while the Bacteroides increased with Ruminococcaceae decreasing in genus level. Lactobacillus was the potentially beneficial genus. Conclusion: Patients developing anti-PD-1 associated colitis have characteristic clinical and pathological manifestations. Glucocorticoids are effective treatment. The fecal microbiome diversity, relative abundance of major phylum and genus have changed after treatment.

Abstract
Vaginal dysbiosis is characterised by a disturbed vaginal microbiota and is associated with various gynaecological diseases. Owing to its high recurrence rate, there is an urgent need for the development of effective therapeutic agents. In the present study, a vaginal dysbiosis model was developed to study the effect of vaginal microbiota transplantation (VMT) or probiotic combination (containing Lactobacillus helveticus, Lactobacillus crispatus, Lactobacillus acidophilus, Lactobacillus gasseri and Lactobacillus salivarius) on vaginal dysbiosis. Our results indicated that VMT or probiotic combination significantly reduced bacterial-induced inflammation (infiltration of neutrophils, lymphocytes and monocytes) in the uterine wall and the enrichment of pro-inflammatory cytokines [interleukin-1β (IL-1β) and tumour necrosis factor-alpha (TNFα)] in vaginal tissue, and restored the disturbed vaginal microbiota to normal levels (increased numbers of Lactobacillus and decreased numbers of Enterobacter and Enterococcus), thus it should be beneficial for avoiding the recurrence of vaginal dysbiosis. Therefore, VMT or probiotic combination might be an effective agent for the treatment of bacterial-induced vaginosis.

Abstract
Background: Epithelial ovarian cancer (EOC) accounts for the most lethal of all gynaecological cancers which is attributed to metastasis, invasiveness and drug resistance. A crucial link has been found between epithelial-mesenchymal transition (EMT) and cancer metastasis and chemo-resistance. Previous studies have confirmed that one of the main components of tripterygium glycosides (GTW)-triptolide (TPL) has anticancer effects. Methods: The purpose of this study is to determine whether GTW could inhibit EMT in A2780/DPP cells in vitro and in vivo, and explore the underlying mechanism. Results: In vitro results showed that GTW inhibited cell proliferation, invasion and migration, and intensified the sensitivity of A2780/DDP cells to cisplatin (DDP). GTW, especially GTW+DDP, significantly inhibited the expression of N-cadherin, integrin-linked kinase (ILK), phospho-protein kinase B/AKT (PKB/p-AKT), phospho-glycogen synthase kinase (p-GSK3β) and Slug, while it increased E-cadherin levels by inhibiting EMT via the ILK/AKT/GSK3β/Slug signalling pathway. Animal results indicated that GTW, especially GTW+DDP, significantly reduced tumour burden, prolonged the life span of mice, and down-regulated the levels of tumour markers CA125 and HE4 by regulating EMT through the ILK/AKT/GSK3β/Slug signalling pathway. Conclusion: Our results highlighted the significance of EMT in EOC metastasis, invasiveness and resistance to DDP and investigated the potential role of GTW as an adjuvant therapeutic agent in chemo-resistant EOC.

Abstract
Cervical cancer is the fourth most prevalent cancer type among all malignancies, so it is of great significance to find its actual pathogenesis mechanisms. In the present study, 90 women were enrolled, and high-throughput sequencing technology was firstly used to analyze the vaginal microbiota of healthy women (C group), cervical intraepithelial neoplasia patients (CIN group) and cervical cancer patients (CER group). Our results indicates that compared with C group, a higher HPV infection rate as well as increased Neutrophil ratio and tumor marker squamous cell carcinoma antigen (SCCA) were obtained, and a decrease in Lymphocyte ratio and Hemoglobin were also present. In addition, the cervical cancer showed a strong association with reduced probiotics Lactobacillus, increased pathogens Prevotella spp., Sneathia spp. and Pseudomonas spp. These results prove that the immunological changes generated by the cervical cancer and the vaginal microbiota can interact with each other. However, further study investigating the key bacteria for cervical cancer is still needed, which can be a clue for the diagnosis or treatment of cervical cancer.

Abstract
Objective: Modeling the immune-related adverse events (irAE) colitis in mice, and explore the protective effect and related mechanism of Lactobacillus rhamnosus GG (LGG) on irAE colitis. Methods: C57BL/6 mice were divided into dextran sodium sulfate (DSS) group (n=3), DSS+anti-programmed death receptor 1 (PD-1) group (n=4), DSS+anti-PD-1+anti-cytotoxic T lymphocyte associated protein 4 (CTLA-4) Group (n=4), DSS+anti-PD-1+anti-CTLA-4+LGG group (n=4), all were given corresponding drugs and probiotics intervention. The severity of colitis were assessed by weight loss, disease activity index (DAI), colon length, colon histopathological score. The inflammatory cytokines and T cell immunity of CD4+, CD8+, FoxP3+regulatory T cells (Treg), were detected by real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and immunohistochemical staining respectively. Results: Compared to DSS group, the Day 9 weight [(87.40±1.79)% vs (94.57±0.53)%, P<0.05], colon length [(5.33±0.27)cm vs (6.63±0.12)cm, P<0.05] were lower, and DAI score(2.66±0.24 vs 0.89±0.48), colon histopathological score (12.50±1.04 vs 5.67±0.33), tumor necrosis factor-α (TNF-α) (6.73±1.68 vs 0.91±0.40) (P<0.05), as well CD8+T cells (156.80±8.84 vs 89.00±6.66) and FoxP3+Treg cells (103.80±2.66 vs 48.33±3.18) (P<0.05) were higher in DSS+anti-PD-1+anti-CTLA-4 group. Compared to DSS+anti-PD-1+anti-CTLA-4 group, the DAI score(1.83±0.17 vs 2.66±0.24), colonic histopathology score (8.75±0.63 vs 12.50±1.04), TNF-α level (1.32±0.18 vs 6.73±1.68) (P<0.05) were lower; and CD8+T cells(97.75±3.75 vs 156.80±8.84, P<0.01) level was lower with higher FoxP3+Treg cells (126.00±8.33 vs 103.80±2.66, P=0.046) in DSS+anti-PD-1+anti-CTLA-4+LGG group. Conclusion: DSS combined with anti-PD-1 and anti-CTLA-4 can successfully modeling the irAE colitis in mice, LGG can reduce irAE colitis severity by regulating Treg cells.

Abstract
This study aims to investigate the value of the combined detection of carcinoembryonic antigen (CEA), Neuron-specific enolase (NSE) and the level of Interleukin-18 (IL-18) in the serum in the diagnosis of lung cancer. The correlation between these parameters and the expression levels of B-cell lymphoma-2 (Bcl-2) protein were also studied. Eighty patients with lung cancer were included in the lung cancer group. These patients underwent surgery in the Department of Oncology of Huai'an Second People's Hospital between February 2016 and February 2018. During the same period, another 80 patients with benign lung lesions were registered in the benign lesion group and 80 healthy people were enrolled in the control group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression levels of CEA, NSE and IL-18. The diagnostic critical value of these factors was used as positive indicator. When CEA, NSE and IL-18 levels were positive at the same time, the combined detection was considered to be positive. WB was used to detect Bcl-2 expression level. We also analyzed the possible correlation between CEA, NSE, IL-18 levels and the Bcl-2 expression levels. The CEA, NSE and IL-18 expression levels in the serum of the lung cancer group were significantly higher than those in the benign lesion and the control groups (p<0.05). The area under ROC curve for CEA, NSE and IL-18 respectively was 0.770 (0.697-0.843), 0.829 (0.767-0.890), 0.721 (0.642-0.800) (p<0.001). IL-18 level was negatively correlated with the level of Bcl-2 mRNA in the tissue (r=-0.380, p<0.001). In conclusion, CEA, NSE and IL-18 have a good auxiliary diagnostic value in patients with lung cancer. The combined detection could improve the sensitivity and specificity of lung can¬cer diagnosis. There was a negative correlation between IL-18 and Bcl-2 levels which suggested a potential inhibitory role of IL-18 on the lung cancer cells apoptosis pathway.

Abstract
Gastric cancer is one of the most common malignant tumors in the world. In China, its morbidity and mortality are second only to lung cancer. Chemotherapy combined with targeted therapy brings survival benefits to patients with advanced gastric cancer. Targets for targeted therapy of gastric cancer include human epidermal growth factor receptor (EGFR), human epidermal growth factor receptor 2 (HER2), vascular endothelial growth factor (VEGF), mammalian target of rapamycin (mTOR) and Claudin 18.2 (CLDN 18.2). The main challenge of tumor molecule-targeted drugs is resistance. The main mechanisms of drug resistance include tumor establishment of compensatory signaling pathways, target protein changes, tumor microenvironment changes, tumor heterogeneity and tumor adaptation to targeted drugs. The combined action of multiple drug resistance mechanisms promotes the development of targeted drug resistance. In order to attract the attention of researchers, this paper reviews the mechanisms of drug resistance in gastric cancer-targeted therapy. In addition, the research status of drug resistance in molecule-targeted therapy of gastric cancer is summarized. It is of great clinical significance to explore the drug resistance mechanisms of targeted drugs and reverse drug resistance in gastric cancer. Last, the future development of molecule-targeted therapy is prospected.

Abstract
The present study aimed to investigate the effects of human umbilical cord mesenchymal stem cells (Huc‑MSCs)‑derived exosomes on the migratory abilities of endometrial glandular epithelial cells, and to evaluate the underlying mechanism from the perspective of epithelial‑mesenchymal transition (EMT). Huc‑MSCs were prepared from human umbilical cord, and eutopic endometrial glandular epithelial cells were isolated from patients with endometriosis. The exosomes derived from Huc‑MSCs (Huc‑MSCs‑exo) were prepared using an exosome extraction kit. The endometrial glandular epithelial cells were randomly divided into two groups: Huc‑MSCs‑exo and control. Cell migratory ability was assessed and western blotting was used to detect the expression levels of EMT. The results of the present study demonstrated that Huc‑MSCs‑exo treatment significantly enhanced the migration of endometrial glandular epithelial cells from patients with endometriosis (P<0.05). The present study also demonstrated that treatment with Huc‑MSCs‑exo inhibited the expression levels of E‑cadherin and promoted the expression levels of Vimentin and N‑cadherin at both the mRNA and protein level. The results of the current study indicate that Huc‑MSCs‑exo enhance the migratory ability of endometrial glandular epithelial cells via promotion of EMT.
