Abstract
Objective: This study aims to explore the temporal trend of Low Anterior Resection Syndrome (LARS) and its symptoms after laparoscopic anterior resection for rectal cancer. Methods: A retrospective cohort study design was employed. The study included primary rectal (adenocarcinoma) cancer patients who underwent laparoscopic anterior resection at Tongji Hospital, Huazhong University of Science and Technology, between January 1, 2010, and December 31, 2020. Complete medical records and follow-up data at 3, 6, 9, 12, and 18 months postoperatively were available for all patients. A total of 1454 patients were included, of whom 1094 (75.2%) were aged ≤65 years, and 597 (41.1%) were females. Among them, 1040 cases (71.5%) had an anastomosis-to-anus distance of 0-5cm, and 86 cases (5.9%) received neoadjuvant treatment. All patients completed the Chinese version of the LARS questionnaire and their LARS occurrence and specific symptom information were recorded at 3, 6, 9, 12, and 18 months postoperatively. Considering past literature and clinical experience, further subgroup analyses were performed to explore the potential impact factors on severe LARS, including anastomosis level, preoperative neoadjuvant therapy, postoperative adjuvant therapy, and the presence of preventive stoma. Results: The occurrence rates of LARS at 3, 6, 9, 12, and 18 months postoperatively were 78.5% (1142/1454), 71.4% (1038/1454), 55.0% (799/1454), 45.7% (664/1454), and 45.7% (664/1454), respectively (χ2=546.180, P<0.001). No statistically significant difference was observed between the 12-month and 18-month time points (P>0.05). When compared with the symptoms at 3 months, the occurrence rates of gas incontinence [1.7% (24/1454) vs. 33.9% (493/1454)], liquid stool incontinence [3.9% (56/1454) vs. 41.9% (609/1454)], increased stool frequency [79.6% (1158/1454) vs. 95.9% (1395/1454)], stool clustering [74.3% (1081/1454) vs. 92.9% (1351/1454)], and stool urgency [46.5% (676/1454) vs. 78.7% (1144/1454)] in the LARS symptom spectrum were significantly alleviated at 12 months (all P<0.05) and remained stable beyond 12 months (all P>0.05). With the extension of postoperative time, the incidence rates of severe LARS exhibited a decreasing trend in different subgroups, of anastomosis level, preoperative neoadjuvant therapy, postoperative adjuvant therapy, and the presence of preventive stoma, and reached stability at 12 months postoperatively (all P>0.05). Conclusion: LARS and its specific symptom profile showed a trend of gradual improvement over time up to 1 year postoperatively, and stabilized after more than 1 year. Increased stool frequency and stool clustering are the most common features of abnormal bowel dys function, which improve slowly after surgery.

Abstract
Helicobacter pylori (H. pylori) is a common pathogen that infects more than half of the world's population. Its infection can not only lead to a variety of gastrointestinal diseases, such as chronic gastritis and gastric cancer (GC) but also be associated with many extra-gastrointestinal diseases. Exosomes, as a new intercellular information transmission medium, can carry biological signal molecules such as microRNAs (miRNAs) to regulate a variety of cellular physiological activities and are involved in multiple cancer processes. In this article, we provide a systematic review on the role of exosomal miRNAs in H. pylori-associated GC.

Abstract
Helicobacter pylori, a Gram-negative microaerobic bacteria belonging to the phylum Proteobacteria, can colonize in the stomach and duodenum, and cause a series of gastrointestinal diseases such as gastritis, gastric ulcer and even gastric cancer. At present, the high diversity of the microorganisms in the stomach has been confirmed with culture-independent methods; some researchers have also studied the stomach microbiota composition at different stages of H. pylori carcinogenesis. Here, we mainly review the possible role of H. pylori-mediated microbiota changes in the occurrence and development of gastric cancer to provide new ideas for preventing H. pylori infection and regulating microecological imbalance.

Abstract
OBJECTIVE To investigate the effects of down-regulating MDR1 gene expression by CRISPRi on enhancing the sensitivity of lung adenocarcinoma A549/DDP cells to cisplatin. METHODS The potential CRISPRi interference sites on the MDR1 gene promoter were predicted by bioinformatics software, and the interference fragments were designed and constructed. The mRNA and protein expression levels of MDR1 gene in each group of cells were detected by qRT-PCR and Western blot methods, and the recombinant vectors with high interference efficiency were screened. Human lung cancer A549/DDP cells were divided into three groups: A549/DDP, Scrambed and sgRNA-MDR1-1, with three multiple holes in each group. After each vector was transfected into the cells for 48 h, the efflux of cells in each group was detected by flow cytometry, the IC50 value of cells in each group was detected by MTT method, and the cell morphology of cells treated with cisplatin was observed under laser confocal microscope. RESULTS After sequencing and comparison, two kinds of CRISPRi recombinant vectors interfering with MDR1 gene transcription were constructed successfully. After transfection of A549/DDP cells, the mRNA and protein levels of MDR1 gene in all transfection groups were decreased significantly (P< 0.01). Among them, the interference efficiency of sgRNA-MDR1-1 was the highest, and the interference efficiency of mRNA and protein was 60% and 51%, respectively. After transfection of sgRNA-MDR1-1 vector, compared with the control group, the efflux ability of cells was decreased (P<0.01), the IC50 value of cells to cisplatin was decreased significantly (P<0.01), and the intracellular chromatin gathered and marginalized, and apoptotic bodies appeared. CONCLUSION CRISPRi interference with MDR1 gene in drug-resistant A549/DDP cells can significantly enhance the sensitivity to cisplatin.

Abstract
4-Coumaric acid: coenzyme A ligase (4CL) is a key enzyme in the phenylpropanoid metabolic pathway that regulates the biosynthesis of lignin and flavonoids. Therefore, the study of 4CL is important to explore the accumulation and regulation of metabolites. This study investigated the role that the 4CL2 gene from Dryopteris fragrans (Df4CL2) plays in the metabolite synthesis. Changes in gene expression, enzyme activity, and the content of lignin and flavonoids were measured in different tissues of tobacco as model plant that was successfully transferred with Df4CL2. Tobacco plants with Df4CL2 (transgenic tobacco, TT) were successfully obtained via the Agrobacterium-transformation method. This TT tended to be thicker and had an earlier flowering period than wild type tobacco (WT). The expression levels of Df4CL2 were higher in the stem, leaf, and root in TT compared to WT. In addition, compared to WT, TT had higher 4CL enzyme activity and higher lignin and flavonoids contents. This suggests that Df4CL2 is involved in the synthesis of lignin and flavonoids in D. fragrans. This research provides important evidence toward understanding the phenylpropanoid metabolic pathway in ferns.

Abstract
Helicobater pylori (H. pylori) is the most important bacteria known to be associated with various gastroduodenal diseases. virB11 gene is a structural gene of tfs3a genes cluster in the plasticity region of H. pylori. In this study, the structure and biology of virB11 gene were analyzed and elucidated with bioinformatics analysis. After cloning, expression and purification, VirB11 protein was generated for the cytotoxicity to GES-1 cells and the anti-VirB11 protein antibody production for localization and interaction proteins analysis. The results showed that VirB11 protein is a hydrophilic protein, mainly locates in cell membrane. IL-8 productions from GES-1 cells co-culture with VirB11 protein were increased gradually with time (p < 0.001). The interaction proteins of VirB11 protein were F0F1 ATP synthase subunit alpha, ATP synthase subunit beta and isocitrate dehydrogenase. We demonstrate that VirB11 protein possesses cytotoxicity and potentially plays important roles in ATP metabolism to provide energy in the course of H. pylori infection.

Abstract
Bloodstream infections remain a leading cause of death worldwide, despite advances in critical care and understanding of the pathophysiology and treatment strategies. No specific biomarkers or therapy are available for these conditions. Neutrophils play a critical role in controlling infection and it is suggested that their migration and antimicrobial activity are impaired during sepsis which contribute to the dysregulation of immune responses. Recent studies further demonstrated that interruption or reversal of the impaired migration and antimicrobial function of neutrophils improves the outcome of sepsis in animal models. In this review, we provide an overview of the associated diagnostic biomarkers involved neutrophils in sepsis, and discuss the potential of neutrophils as a target to specifically predict the outcome of sepsis.

Abstract
Objective: To investigate the causes of 30-day unplanned revision surgery following one-stage posterior vertebral column resection (PVCR) for severe spinal deformity and the methods of prevention and management. Methods: A total of 112 severe deformity patients underwent one-stage PVCR for surgical treatment in the 306(th) Hospital of People's Liberation Army from May 2010 to December 2015 were retrospectively reviewed. Six patients required reoperation within 30 days after PVCR, including 2 males and 4 females with average age of 21 years (ranging from 12 to 38 years). Four cases were congenital kyphoscoliosis, 1 was post-laminectomy kyphoscoliosis and 1 was post-tuberculous angular kyphosis. Three cases associated with preoperative neurologic deficit (Frankel C in 1 patient and D in 2 patients). The causes, management and outcomes of unplanned revision surgery within 30 days after PVCR were recorded. Results: The total incidence of unplanned revision surgery within 30 days following PVCR was 5.4% (6/112). There was 1 case due to cerebrospinal fluid leak, 5 cases with varying degrees of new neurologic deficits, the causes were as followed: dural buckling in 1 case, residual bone compression in 1 case, epidural hematoma compression in 2 cases, spinal subdural hematoma in 1 case. All the 6 cases underwent surgical exploration again, including further dural repair, decompression and hematoma clearance. After unplanned reoperation, 6 cases recovered completely. The average follow-up time after surgery was 30.8 months (ranging from 10 to 60 months). The major curve at coronal plane was improved from preoperative 87.7° to 34.2°, with a mean correction of 61.0% at final follow-up; the sagittal kyphosis curve was improved from preoperative 119.5° to 45.5°, with a mean correction of 61.9% at final follow-up. Two patients' neurological status improved from Frankel D to Frankel E, one patient's neurological status improved from Frankel C to Frankel E. Conclusions: One-stage PVCR could be an effective method for treatment of severe spinal deformity. The causes of 30-day unplanned reoperation after PVCR are as followed: cerebrospinal fluid leak, dural buckling, residual bone compression and hematoma compression. Timely surgical exploration can gain good clinical outcomes.

Abstract
Muscovy duck parvovirus (MDPV) infection is widespread in many Muscovy-duck-farming countries, leading to a huge economic loss. By means of overlapping peptides expressed in Escherichia coli in combination with Western blot, antigenic domains on the non-structural protein (NSP) of MDPV were identified for the first time. On the Western blot, the fragments NS(481-510), NS (501-530), NS (521-550), NS (541-570), NS (561-590), NS (581-610) and NS (601-627) were positive (the numbers in parentheses indicate the location of amino acids), and other fragments were negative. These seven fragments were also reactive in an indirect enzyme-linked immunosorbent assay (i-ELISA). We therefore conclude that a linear antigenic domain of the NSP is located at its C-terminal end (amino acid residues 481-627). These results may facilitate future investigations into the function of NSP of MDPV and the development of immunoassays for the diagnosis of MDPV infection.

Abstract
Up-regulation of multidrug resistance-associated protein 1 (MRP1) is regarded as one of the main causes for multidrug resistance (MDR) of tumor cells, leading to failure of chemotherapy-based treatment for a multitude of cancers. However, whether silencing the overexpressed MRP1 is sufficient to reverse MDR has yet to be validated. This study demonstrated that RNAi-based knockdown of MRP1 reversed the increased efflux ability and MDR efficiently. Two different short haipin RNAs (shRNAs) targeting MRP1 were designed and inserted into pSilence- 2.1-neo. The shRNA recombinant plasmids were transfected into cis-dichlorodiamineplatinum-resistant A549 lung (A549/DDP) cells, and then shRNA expressing cell clones were collected and maintained. Real time PCR and immunofluorescence staining for MRP1 revealed a high silent efficiency of these two shRNAs. Functionally, shRNA-expressing cells showed increased rhodamine 123 retention in A549/DDP cells, indicating reduced efflux ability of tumor cells in the absence of MRP1. Consistently, MRP1-silent cells exhibited decreased resistance to 3- (4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) and DDP, suggesting reversal of MDR in these tumor cells. Specifically, MRP1 knockdown increased the DDP-induced apoptosis of A549/DDP cells by increased trapping of their cell cycling in the G2 stage. Taken together, this study demonstrated that RNAi- based silencing of MRP1 is sufficient to reverse MDR in tumor cells, shedding light on possible novel clinical treatment of cancers.

Abstract
Microsomal omega-6 fatty acid desaturase (FAD2-1B) is an enzyme that regulates the polyunsaturated fatty acid content in soybeans (Glycine max). In this study, the FAD2-1B gene was determined to be highly expressed in soybean seeds using quantitative real-time PCR(qRT-PCR). To investigate the expression pattern and activity of the FAD2-1B promoter, a 1929 bp 5'-upstream genomic DNA fragment, named PF, was isolated according to the soybean genomic sequence. Sequence analysis revealed the presence of many motifs related to seed-specific promoters in the PF fragment, such as E-box, SEF4, Skn-1 motif, AACACA, AATAAA and so on. Tobacco transgenics carrying the gus reporter gene driven by the PF and/or 35S promoters were confirmed by PCR and RT-PCR. qRT-PCR and histochemical GUS assays showed that the PF promoter could regulate gus gene accumulation in seeds and the expression level was higher than in other organs. In the meantime, it exhibited similar activity to the 35S promoter in seeds, which could be associated with seed-related cis-elements found in the 1-248 bp, 451-932 bp, and 1627-1803 bp regions of the promoter.

Abstract
This paper was aimed to study conserved motifs of voltage sensing proteins (VSPs) and establish a voltage sensing model. All VSPs were collected from the Uniprot database using a comprehensive keyword search followed by manual curation, and the results indicated that there are only two types of known VSPs, voltage gated ion channels and voltage dependent phosphatases. All the VSPs have a common domain of four helical transmembrane segments (TMS, S1-S4), which constitute the voltage sensing module of the VSPs. The S1 segment was shown to be responsible for membrane targeting and insertion of these proteins, while S2-S4 segments, which can sense membrane potential, for protein properties. Conserved motifs/residues and their functional significance of each TMS were identified using profile-to-profile sequence alignments. Conserved motifs in these four segments are strikingly similar for all VSPs, especially, the conserved motif [RK]-X(2)-R-X(2)-R-X(2)-[RK] was presented in all the S4 segments, with positively charged arginine (R) alternating with two hydrophobic or uncharged residues. Movement of these arginines across the membrane electric field is the core mechanism by which the VSPs detect changes in membrane potential. The negatively charged aspartate (D) in the S3 segment is universally conserved in all the VSPs, suggesting that the aspartate residue may be involved in voltage sensing properties of VSPs as well as the electrostatic interactions with the positively charged residues in the S4 segment, which may enhance the thermodynamic stability of the S4 segments in plasma membrane.

Abstract
BACKGROUND AND OBJECTIVE Epithelial ovarian cancer involves a number of factors. Recent studies have shown that osteopontin (OPN) is related to the occurrence and development of a variety of tumors, but few studies are on ovarian cancer. B7-H4 is a newly identified tumor marker in ovarian cancer. This study explored the expression of OPN and B7-H4 and their clinical significance in epithelial ovarian tumors. METHODS The expression of OPN and B7-H4 in 15 cases of normal ovarian tissue, 20 of benign ovarian tumor tissue, 20 of borderline ovarian tumor tissue, and 40 of ovarian cancer tissue were detected by immunohistochemistry, and the relationship of OPN and B7-H4 expression to clinical and pathologic features of ovarian cancer was analyzed. RESULTS The expression of OPN and B7-H4 were significantly higher in ovarian cancer than in borderline and benign tumors (P<0.05). The positive rates of OPN and B7-H4 were significantly higher in poorly differentiated ovarian cancer than in medium and highly differentiated ovarian cancer (P<0.05), and the levels of expression were significantly lower in tissue at stages I and III of ovarian cancer than in stages III and IV (P<0.05). The positive rate of OPN associated with a higher rate of lymph node metastasis (P<0.05), but did not relate to age and histologic type. The positive rate of B7-H4 were significantly higher in ovarian serous carcinoma than in the mucinous carcinoma (P<0.05), but did not relate to age and lymph node metastasis. CONCLUSION The expression of OPN and B7-H4 increased in epithelial ovarian cancer, which could be referenced in the diagnosis of ovarian malignant tumors.

Abstract
The polymorphism of hemoglobin (Hb), serum albumin (Alb), trandferring (Tf) and adenosin deaminase (Ada) in the blood of Emberiza elegans, Phylloscopus inornatus, E. aureola, Lanius tigrinus, Passer montanus, and E. spodocephala in Zhalong National Nature Reserve were studied by SDS-polyacrylamide-gel electrophoresis. All the protein loci of the six Passeriformes species exhibited polymorphism, and Ada locus had a relatively high heterozygosity. The analysis of average heterozygosity demonstrated that P. inornatus had a higher population genetic variance, while E. spodocephala was relatively stable. The six species could be classified into two clusters. E. elegans, E. aureola, E. spodocephala and P. inornatus were clustered into one group, while P. montanus and L. tigrinus were clustered into another group. This clustering was consistent with the actual taxonomic status of the six species. The higher thermoregulation index and predation pressure of the study area did not lead to the substantial variation of hereditary constitution of the six species, possibly due to the gene intercommunion between the six species and the outside of the study area, which decreased the variance and differentiation of the population genetics of the six species.

Abstract
BACKGROUND & OBJECTIVE Cancer cell growth is supported by glucose metabolism of glucose transporter protein 1 (GLUT-1). In addition, the participation of DNA-dependent protein kinase catalytic subunit (DNA-PKcs) in genome damage-repairing is important for oncogenesis prevention. This study was to evaluate the expression and biologic significance of GLUT-1 and DNA-PKcs in serous ovarian tumors. METHODS The expression of GLUT-1 and DNA-PKcs in 20 specimens of normal ovarian tissues, 20 specimens of serous cystadenoma, 20 specimens of borderline serous cystadenoma, and 40 specimens of serous cystadenocarcinoma were detected by SP immunohistochemistry. The correlation of GLUT-1 and DNA-Pkcs expression to clinicopathologic characteristics of serous ovarian tumors was analyzed by Chi-square test. RESULTS The positive rate of GLUT-1 was significantly higher in malignant and borderline serous ovarian carcinomas than in benign tumors and normal ovarian tissues (100% and 55% vs. 0% and 0%, P<0.01). The differences in the positive rate of DNA-PKcs were significant among normal ovarian tissues, benign, borderline, and malignant serous ovarian tumors (100%, 95%, 90%, and 60%, P<0.01). GLUT-1 expression was negatively correlated to DNA-PKcs expression (rs = -0.270, P<0.01). GLUT-1 expression in borderline and malignant serous ovarian tumors was related to intraperitoneal implants, ascites, lymph node metastasis, and FIGO stage, but DNA-PKcs was only related to FIGO stage and lymph node metastasis (P<0.05). CONCLUSION The expression of GLUT-1 and the loss of DNA-PKcs may be closely related to the malignant transformation of serous ovarian tumors.

Abstract
OBJECTIVE To investigate the expression of GLUT1, p63 and DNA-Pkcs in serous ovarian tumors and their significance. METHODS GTUL1, p63 and DNA-Pkcs expression at protein level was detected by immunohistochemistry in patients with serous ovarian tumors. Chi-square analysis was used to assess if their expression is associated with clinicopathologic characteristics of the tumors. RESULTS Cells in the normal ovarian tissues were not stained with GTUL1 and p63 antiserum, but DNA-Pkcs was positively stained. The intensity of GTUT1 and p63 expression was stronger in malignant ovarian serous tumors compared with other subtypes (P < 0.01). There were significant differences of DNA-PKcs among normal ovaries (100.0%), benign (95.0%), borderline (90.0%) and malignant (60.0%) serious ovarian neoplasms (P < 0.01). The level of GLUT-1 expression was correlated with FIGO staging, intraperitoneal implantation, ascites and lymph node metastasis (P < 0.05). p63 expression was associated with clinicopathologic characteristics except ascites (P < 0.05). DNA-PKcs was only correlated with FIGO staging and lymph node metastasis (P < 0.05). CONCLUSION The results suggest that the abnormal expression of GTUT1, p63 and DNA-Pkcs may perhaps participate in serous ovarian tumor occurrence and development and may be considered as a marker reflecting tumor malignant behavior.

Abstract
Platelet aggregation and thromboxane B2 (TXB2) production induced by arachidonic acid (AA) or Adenosine diphosphate (ADP) were studied by turbidimetry and radioimmunoassay in rabbits. 3,4,5-tri-hydroxystibene-3-beta-mono-D-glucoside (PD) 6.7-107.2 mumol/L inhibited platelet aggregation and the production of TXB2 as well. The inhibitions by PD were dose-dependent: 48-90% (AA-induced) and 43-69% (ADP-induced) for platelet aggregation; 50-87% (AA-induced) and 43-68% (ADP-induced) for TXB2. There were positive correlations between the inhibition of platelet aggregation and production of TXB2.
