Abstract
BACKGROUND After abdominoperineal resection, low anterior resection, and end colostomy for lower rectal cancer, it is necessary to reconstruct the pelvic peritoneum to avoid small bowel obstruction, perineal hernia, and radiation enteritis in patients for whom postoperative radiotherapy is planned. However, pelvic peritoneal closure is technically difficult in patients who lack enough peritoneum to cover the defect or have received neoadjuvant radiation and have a rigid pelvis. IMPACT OF INNOVATION The impact of this innovation is to reconstruct the pelvic peritoneum with the distal ileal mesentery laparoscopically. TECHNOLOGY, MATERIALS AND METHODS After removal of the tumor, the distal ileal mesentery was selected to completely cover the defect. Subsequently, suturing of the ileal mesentery to the posterior wall of the urinary bladder and all sides of the pelvic cavity was performed. Finally, the patients were returned to the headfirst supine position to ensure that there was no small bowel falling into the pelvic dead space. PRELIMINARY RESULTS All surgical procedures were successfully performed laparoscopically from January 2019 to April 2021. No perineal complications or intestinal obstructions occurred during the follow-up period. CONCLUSIONS AND FUTURE DIRECTIONS This novel technique was found to be safe and effective. Moreover, it provided an economical method for the reconstruction of the pelvic peritoneum using autologous material, which could preserve the small intestine in the abdomen to avoid related complications. Additional larger series of patients with longer follow-up are needed to validate the safety and feasibility of this method.

Abstract
Purpose: To determine the role and mechanisms of Krüppel-like transcription factor 8 (KLF8) in acute myeloid leukemia (AML).Methods: The transcriptional and translational levels of KLF8 in AML cell lines were determined by quantitative real time-polymerase chain reaction (qRT-PCR) and western blotting. Two RNAs targeting KLF8 were transfected into KG-1 and HL-60 cells. The growth and apoptosis of AML cells were determined using CCK-8, 5-ethynyl-2-deoxyuridine (EdU), flow cytometry, and western blot assays. Glycolysis was evaluated by relative glucose consumption, lactate generation, ATP levels, and hexokinase II (HK2), while glucose transporter 1 (GLUT1) protein expression levels. AKT, phosphorylated AKT (p-AKT), mammalian target of rapamycin (mTOR), and p-mTOR expression levels were assessed by western blot.Results: KLF8 mRNA and protein expression levels were elevated in AML cells (p < 0.01). KLF8 knockdown in AML cells decreased cell viability, EdU-positivity, relative glucose consumption, lactate generation, ATP levels, and HK2 and GLUT1 protein levels (p < 0.01). Apoptosis increased in KG-1 and HL-60 cells, with enhanced Bax and reduced Bcl-2 protein levels, after transfection with sh-KLF8. The relative expression levels of p-AKT/AKT and p-mTOR/mTOR were reduced in KG-1 and HL-60 cells transfected with sh-KLF8.Conclusion: Downregulation of KLF8 inhibits proliferation and glycolysis, and also promotes apoptosis in AML cells via AKT/mTOR pathway.

Abstract
BACKGROUND This study aimed to evaluate the safety and therapeutic effect of Robot-assisted surgery (RAS) for choledochal cysts (CCs) excisions. RESEARCH DESIGN AND METHODS PubMed, EMBASE, Cochrane Library, Web of Science, CNKI, WanFang, VIP, and CBM were searched from database inception to 1 May 2022. The Newcastle-Ottawa scale (NOS) was used to conduct quality assessments, and RevMan (Version 5.4) was used to perform the meta-analysis. RESULTS In all, 9 studies, involving 623 patients, were analyzed. RAS compared with LAS was associated with less intraoperative blood loss, shorter time to start solid diets, shorter postoperative hospital stay, and lower complications. There was no significant difference in operative time between the two groups, but the total costs were higher in RAS. Our subgroup analysis showed that RAS had significant advantages over LAS in the child group: minor bleeding, shorter length of hospital stay, and fewer postoperative complications. CONCLUSIONS The available evidence indicates that the RAS system has the advantages of less intraoperative blood loss, minor tissue damage, quick recovery, and sound healing in treating choledochal cyst, which proves that the RAS is safely feasible. Especially in children, RAS tends to be a better choice.

Abstract
Primary hepatic neuroendocrine carcinoma (PHNEC) manifests as a rare type of liver tumor. PHNEC is not specifically clinical or radiographical and is often misdiagnosed and mistreated. Here, we present a case report of PHNEC in a 50-year-old woman who was admitted to our department with concealed pain in the right upper abdomen. The initial diagnosis was a probable hepatic space-occupying lesion with tumor bleeding. The patient was subjected to a partial right hemihepatectomy, cholecystectomy, partial resection of the lower lobe of the right lung, partial resection of the diaphragm, and resection of the right perirenal fat sac to alleviate her symptoms. After surgery, gene sequencing was performed to determine the possible cause of the condition. However, five months after discharge, the patient was hospitalized again because of retroperitoneal and peritoneal multiple metastases. Nine months after surgery, the patient died. This case is likely to aid in furthering our understanding of PHNEC to improve the future diagnosis and treatment of this disease.

Abstract
As one of the leading causes of death, hematologic malignancies are associated with an ever-increasing incidence, and drug resistance and relapse of patients after treatment represent clinical challenges. Therefore, there are pressing demands to uncover biomarkers to indicate the development, progression, and therapeutic targets for hematologic malignancies. Circular RNAs (circRNAs) are covalently closed circular-single-stranded RNAs whose biosynthesis is regulated by various factors and is widely-expressed and evolutionarily conserved in many organisms and expressed in a tissue−/cell-specific manner. Recent reports have indicated that circRNAs plays an essential role in the progression of hematological malignancies. However, circRNAs are difficult to detect with low abundance using conventional techniques. We need to learn more information about their features to develop new detection methods. Herein, we sought to retrospect the current knowledge about the characteristics of circRNAs and summarized research on circRNAs in hematological malignancies to explore a potential direction.

Abstract
In this study, we selected eight cis-elements: AAAG, ACGTG, CCGA, ACTCAT, GGTCA, TATCC, TGAC and GATAA, which are closely related to plant growth and development, signal transduction and stress response. The CEAP primers were 18 nucleotides long and consisted of a central cis-element nucleotide core flanked by a filler sequence at the 5' end and di- or tri-nucleotides at the 3' end. A total of two hundred and twenty-four primers were developed, and the PCR procedure consisted of 5 cycles of low-temperature annealing and 35 subsequent cycles of annealing at 50°C. The PCR products are electrophoretically separated by 1.8-2.3% agarose. The polymorphism of the CEAP marker was amplified in eight mango (Mangifera indica L.) species. The results showed that the CEAP primers could amplify clear, repeatable bands in mango and combine at least four cis-elements from which a large number of bands were amplified and six highly polymorphic primers for each cis-element can reach an accurate clustering result. The results of CEAP marker assays compared with ISSR, CBDP and iPBS marker assays showed that CEAP marker was better than the other three markers in the number of fragment bands, H and I indexes. In addition, we also tested the CEAP markers in rice, tomato, potato, wax gourd, citrus and longan and the results showed that the CEAP marker assay could amplify clear polymorphic bands in different species. Our results indicate that the CEAP markers could be universally used in different species for genetic diversity analysis, relationship analysis, and marker-assisted selection for breeding.

Abstract
Osteoarthritis is a worldwide joint disease caused by abnormal chondrocytic metabolism. However, traditional therapeutic methods aimed at anti-inflammation for early-stage disease are palliative. In the present study, we demonstrated that cepharanthine (CEP), extracted from the plant Stephania cepharantha, exerted protective medicinal efficacy on osteoarthritis for the first time. In our in vitro study, CEP suppressed the elevated expression of matrix metalloproteinases (MMPs), a disintegrin and metalloproteinase with thrombospondin motifs 5 (ADAMTS5) and inducible nitric oxide synthase (iNOS) stimulated by IL-1β or TNF-α by inhibiting the activation of MAPK and NF-κB signaling pathways, and upregulated the protein expression of aggrecan, collagen II, and Sox9. Also, CEP could reverse the reduced level of cellular autophagy in IL-1β or TNF-α–induced chondrocytes, indicating that the protective effect of CEP on osteoarthritis was achieved by restoring MAPK/NF-κB-mediated autophagy. Furthermore, in a murine OA model, CEP mitigated cartilage degradation and prevented osteoarthritis in the CEP-treated groups versus the OA group. Hence, our results revealed the therapeutic prospect of CEP for anti-osteoarthritic treatment.

Abstract
Background Cancer is one of the leading causes of death worldwide. Early diagnosis can significantly lower cancer-related mortality. Studies have shown that the lncRNA Forkhead box P4 antisense RNA 1 (FOXP4-AS1) is aberrantly expressed in various solid tumors. A meta-analysis was performed to evaluate the correlation of FOXP4-AS1 with the prognosis of cancer patients and determine the clinical value of FOXP4-AS1 as a potential diagnostic marker. Methods Correlational studies from the Web of Science, Embase, OVID, Cochrane and PubMed databases were screened (up to April 1, 2021). Meta-analysis was performed using Stata SE12.0 software. Results Eleven original studies with 1,332 patients who were diagnosed with a solid cancer (nasopharyngeal carcinoma, hepatocellular carcinoma, colorectal cancer, gastric cancer, osteosarcoma, mantle cell lymphoma, prostate cancer, and pancreatic ductal adenocarcinoma) were included in the meta-analysis. High expression of FOXP4-AS1 was correlated with poor overall survival (OS) (HR = 1.77, 95% CI 1.29-2.44, P < 0.001) and shorter disease-free survival (DFS) (HR = 1.66, 95% CI 1.01-2.72, P = 0.044). Subgroup analysis based on sample size, follow-up time and Newcastle-Ottawa Scale (NOS) score revealed significant differences between FOXP4-AS1 levels and OS (P < 0.05). However, the expression level of FOXP4-AS1 was not significantly correlated with the OS of gastric cancer patients (P = 0.381). High expression of FOXP4-AS1 was predictive of a larger tumor size (OR = 3.82, 95% CI 2.3-6.3, P < 0.001). Conclusions Overexpression of FOXP4-AS1 correlates with poor prognosis of cancer patients, and is a potential prognostic biomarker and therapeutic target.

Abstract
Objective: The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China. Methods: This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems. Results: According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%). Conclusion: Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Abstract
AbstractThis study presents a multi-objective optimization model to solve aircraft landing problem within a predetermined time window. Minimizing total fuel cost, minimizing total delays, maximizing throughput, and maximizing fairness are considered to construct the multi-objective optimization model. According to the different weights of objectives, the first-come-first-serve and simulated annealing are used to solve the multi-objective optimization problem. The algorithms’ feasibility is analysed and a suggestion about how to get satisfactory solutions for all stakeholders is given through the expert evaluation method. The results show that the simulated annealing can get better solution than the first-come-first-serve when the number of flights exceeds 10.

Abstract
Surgical resection remains the best choice for the treatment of liver tumors. Hepatectomy combined with artificial vascular reconstruction has been proven as an alternative to treating tumors involving the main hepatic veins. As the cutting-edge surgical technique, robotic liver surgery is a novel procedure expanding the field of minimally invasive approaches, especially in complex reconstruction. This study reports, for the first time, on a robotic hepatectomy with middle hepatic vein (MHV) reconstruction using an expanded polytetrafluoroethylene (ePTFE) graft for a patient with hepatic adenoma. The tumor, which was located in segment 8, was adjacent to the MHV. Robot-assisted resection of segment 4 and partial segment 8, and MHV reconstruction using a ePTFE graft were performed. During the post-operative examination and follow-up, the blood flow of the ePTFE graft was patent, and liver function recovered well. Thus, robotic hepatectomy with MHV reconstruction is a safe, minimally invasive, and precise surgery that may provide a novel approach for patients with liver tumors that are invading or adjacent to the main hepatic veins.

Abstract
BACKGROUND The incidence of adenocarcinoma of the esophagogastric junction (AEG) has rapidly increased in recent years. Popular surgical approaches for AEG are proximal gastrectomy (PG) and total gastrectomy (TG), but it is controversial as to which approach is superior. Therefore, we conducted a systematic review and meta-analysis to evaluate the short- and long-term clinical outcomes of PG and TG for AEG. METHODS PubMed, Embase, Web of Science, and Cochrane Library were searched from inception to 1 June 2021. The Newcastle-Ottawa scale was used to conduct quality assessments, and RevMan (Version 5.4) was used to perform the meta-analysis. RESULTS In all, 1,734 patients with Siewert II/III AEG in 12 studies were included in the meta-analysis. PG was associated with less number of harvested lymph nodes (WMD = - 9.00, 95% CI - 12.61 to - 5.39, P < 0.00001), smaller tumor size (WMD = - 1.02, 95% CI - 1.71 to - 0.33, P = 0.004), shorter hospital length of stay (WMD = - 3.99, 95% CI - 7.27 to - 0.71, P = 0.02), and better long-term nutritional status compared with TG. Overall complications, other complications, and overall survival were not significantly different between the two groups. Moreover, subgroup analysis revealed that the occurrence of anastomotic strictures and reflux esophagitis was associated with the use of novel gastrointestinal tract (GI) anastomoses (double-tract reconstruction, jejunal interposition, and semi-embedded valve anastomosis) after PG. CONCLUSIONS Based on the available evidence, we recommend that surgeons accept PG combined with multiple novel anastomoses as an optimal surgical approach in patients diagnosed with resectable Siewert type II/III AEG.

Abstract
PURPOSE In the present work, we investigated the expression pattern of miR-4463 in the non-metastasis and metastasis colorectal cancer (CRC) patients and its regulation axis. METHODS RT-qPCR assay was performed to assess miR-4463 expression in the serum and tissues of patients with non-metastasis and metastasis, and in the CRC cell lines. MTT assay, colony formation assay, transwell assay, and flow cytometry assay were used to examine the role of miR-4463 in CRC cell viability, proliferation, and migration. Bioinformatic analysis was used to identify the potential target gene of miR-4463, and the targeting relationship between miR-4463 and PPP1R12B was verified in vitro using dual luciferase assay. Western blotting assay was used to determine the protein level of the target gene PPP1R12B in CRC cells under the transfections of miR-4463 mimic, inhibitor and vectors overexpressing PPP1R12B. RESULTS miR-4463 was markedly increased in the non-metastasis CRC tissues, and increased even higher in the metastasis CRC tissues, while miR-4463 expression had no significant difference in serum from non-metastasis and metastasis CRC samples. Besides, miR-4463 was upregulated in CRC cell lines. Functionally, miR-4463 promoted CRC cell proliferation, migration, and inhibiting cell apoptosis. Further analysis revealed that the miR-4463/PPP1R12B axis was responsible for the role of this miRNA. CONCLUSION We reported the roles of miR-4463 in CRC proliferation and migration, supporting that miR-4463 could be a potential predictive diagnostic marker for colon cancer.

Abstract
BACKGROUND Both radiofrequency ablation (RFA), photodynamic therapy (PDT), and biliary stent alone are common local palliative therapies for unresectable malignant biliary obstruction (MBO), but the best modality is uncertain. RESEARCH DESIGN AND METHODS Embase, Cochrane Library, PubMed, and Web of Science were systematically searched up to 30 January 2022, for eligible studies that compared either two or all modalities in unresectable MBO. RESULTS Thirty-three studies with 2974 patients were included in this study. The PDT+Stent and RFA+Stent groups had better overall survival and longer mean survival time than Stent alone (all P < 0.05). Moreover, patients with RFA+Stent demonstrated better mean duration of stent patency (MD: 2.0, 95%CI,1.1 to 2.8, P < 0.05) than Stent alone. The three modalities had similar postoperative mild bleeding, cholangitis, and pancreatitis (all P ≥ 0.05). According to network ranking, PDT+Stent was most likely to provide better survival, RFA+Stent was most likely to maintain stent patency. CONCLUSIONS RFA or PDT plus biliary stent is effective and safe local palliative therapy for unresectable MBO, but the current studies cannot absolutely determine which modality is the best. We should offer patients the most appropriate treatment according to the advantage of each therapy and the patient's performance status.

Abstract
Termites are major decomposers in terrestrial ecosystems and the second most diverse lineage of social insects. The Kalotermitidae form the second-largest termite family and are distributed across tropical and subtropical ecosystems, where they typically live in small colonies confined to single wood items inhabited by individuals with no foraging abilities. How the Kalotermitidae have acquired their global distribution patterns remains unresolved. Similarly, it is unclear whether foraging is ancestral to Kalotermitidae or was secondarily acquired in a few species. These questions can be addressed in a phylogenetic framework. We inferred time-calibrated phylogenetic trees of Kalotermitidae using mitochondrial genomes of ∼120 species, about 27% of kalotermitid diversity, including representatives of 21 of the 23 kalotermitid genera. Our mitochondrial genome phylogenetic trees were corroborated by phylogenies inferred from nuclear ultraconserved elements derived from a subset of 28 species. We found that extant kalotermitids shared a common ancestor 84 Ma (75–93 Ma 95% highest posterior density), indicating that a few disjunctions among early-diverging kalotermitid lineages may predate Gondwana breakup. However, most of the ∼40 disjunctions among biogeographic realms were dated at <50 Ma, indicating that transoceanic dispersals, and more recently human-mediated dispersals, have been the major drivers of the global distribution of Kalotermitidae. Our phylogeny also revealed that the capacity to forage is often found in early-diverging kalotermitid lineages, implying the ancestors of Kalotermitidae were able to forage among multiple wood pieces. Our phylogenetic estimates provide a platform for critical taxonomic revision and future comparative analyses of Kalotermitidae.

Abstract
Hepatocellular carcinoma (HCC) is the most common pathological type of primary hepatic carcinoma. This study investigated the effects of ginsenoside Rg3 (Rg3) and sorafenib (SFN) combination therapy on HCC progression. The HCC-related data were obtained from TCGA database, and the data of HK2 mRNA, clinicopathological features, and survival outcomes were extracted using R Programming 4.0. The human hepatoma cell lines HepG2 and Bel7404 were used. Cell viability was tested using the MTT assay. Glucose consumption and lactate levels of HCC cells were detected using the corresponding kits. Western blotting was used to determine the protein expression of HK2, PI3K, and Akt. HK2 was overexpressed in patients with HCC. Compared with patients with overexpressed HK2, those with low levels of HK2 achieved a longer survival time. In addition, the Rg3 and SFN combination therapy significantly reduced cell viability, glucose consumption, lactate levels, and protein expression of HK2, PI3K, and Akt in HCC cells. Additionally, the Rg3 and SFN combination therapy exhibited a better effect than the single drug group. Inhibition of the PI3K/Akt signaling pathway or exogenous lactate intervention reversed the effects of Rg3 and SFN combination therapy in HCC cells. In conclusion, Rg3 has a synergistic effect on the sensitivity of HepG2 and Bel7404 hepatoma cells to SFN, which is related to HK2-mediated glycolysis and the PI3K/Akt signaling pathway.

Abstract
BACKGROUND CNS B-cell lymphoma mimicking demyelinating diseases creates a diagnostic dilemma. This study aimed to determine the specific MR features of CNS B-cell lymphoma to facilitate the early identification of the disease. METHODS We retrospectively reviewed the brain MRI of biopsy-confirmed CNS B-cell lymphoma patients. They were initially diagnosed with CNS demyelination, and these images were compared with those of actual patients with demyelinating diseases. RESULTS A total of 20 patients with CNS B-cell lymphoma and 12 patients with demyelination were included in this study. Cohesive enhancement with satellite enhancing foci surrounded by prominent non-enhancing areas of oedema is the major contrast-enhancing pattern of lymphoma patients, accounting for 81% (13) of patients with primary diffuse large B-cell lymphoma (DLBCL). This imaging pattern revealed a sensitivity of 81% and a specificity of 75% for lymphoma in the differential diagnosis between primary DLBCL and demyelinating disease in our cohort. Among these lesions, most of the nodules were located deeply, which yielded a specificity of 100% and a sensitivity of 69% for primary DLBCL. Enhancement in a single pattern (mainly ring-like, patchy or punctate) (57%) and no enhancement (30%) were commonly observed in demyelinating lesions, distinct from primary DLBCL (p<0.05). CONCLUSIONS Lesions with cohesive enhancement and satellite foci on T1 contrast-enhanced imaging could be a specific hallmark of CNS B-cell lymphoma, suggesting the need to withdraw steroidal therapy withdrawal and biopsy confirmation.

Abstract
PURPOSE It remains a technical challenge to perform "superior mesenteric artery (SMA) first" approach for laparoscopic right hemicolectomy with complete mesocolon excision (CME) as the vascular anatomy of the right colon varies a lot, which may cause difficulty in early location of SMA and the risk of vascular damage during central vascular ligation (CVL). The purpose of this study was to describe a new "SMA first" approach for laparoscopic CME with CVL in right hemicolectomy with Treitz's ligament and ileocolic vascular pedicle as the anatomical landmarks for early identification of and exposure of SMA. METHODS This procedure was performed on 21 patients with right colon cancer between March 2020 and August 2021. To start, the transverse mesocolon was retracted to expose the ligament of Treitz, and the pedicle of ileocolic vessels was anteriorly grasped. Next, the peritoneum near the right border of the ligament of Treitz was divided along the left side of SMA until the peritoneum below the ileocolic vessels. Next, the mesenteric lymphatic adipose tissue outside of the sheath of SMA was dissected from medial to lateral. Then, laparoscopic right hemicolectomy with complete mesocolic excision (CME) was performed. Patients' preoperative baseline characteristics and intraoperative and postoperative complications were examined. RESULTS The median operative time was 180 min, and the median intraoperative blood loss was 50 ml (interquartile range 40-90). Chylous leakage occurred in four patients, and all the patients resolved with percutaneous drainage. The total harvested lymph nodes was 21.0 (range 16-27). The median times to first flatus and liquid diet intake were both 3.0 days. The median number of postoperative hospital days was 10.0 days. No severe postoperative complications, such as abdominal infection, anastomotic leakage, or bleeding, were observed. CONCLUSIONS This new "SMA first" approach is safe and technically feasible for laparoscopic CME with CVL in right hemicolectomy.
