Abstract
Xyloglucan, an important hemicellulose, plays a crucial role in maintaining cell wall structure and cell elongation. However, the effects of xyloglucan on cotton fiber development are not well understood. GhMUR3 encodes a xyloglucan galactosyltransferase that is essential for xyloglucan synthesis and is highly expressed during fiber elongation. In this study, we report that GhMUR3 participates in cotton fiber development under the regulation of GhMYB30. Overexpression GhMUR3 affects the fiber elongation and cell wall thickening. Transcriptome showed that the expression of genes involved in secondary cell wall synthesis was prematurely activated in OE-MUR3 lines. In addition, GhMYB30 was identified as a key regulator of GhMUR3 by Y1H, Dual-Luc, and electrophoretic mobility shift assay (EMSA) assays. GhMYB30 directly bound the GhMUR3 promoter and activated GhMUR3 expression. Furthermore, DAP-seq of GhMYB30 was performed to identify its target genes in the whole genome. The results showed that many target genes were associated with fiber development, including cell wall synthesis-related genes, BR-related genes, reactive oxygen species pathway genes, and VLCFA synthesis genes. It was demonstrated that GhMYB30 may regulate fiber development through multiple pathways. Additionally, GhMYB46 was confirmed to be a target gene of GhMYB30 by EMSA, and GhMYB46 was significantly increased in GhMYB30-silenced lines, indicating that GhMYB30 inhibited GhMYB46 expression. Overall, these results revealed that GhMUR3 under the regulation of GhMYB30 and plays an essential role in cotton fiber elongation and secondary wall thickening. Additionally, GhMYB30 plays an important role in the regulation of fiber development and regulates fiber secondary wall synthesis by inhibiting the expression of GhMYB46.

Abstract
Vascular Plant One‑zinc Finger (VOZ) transcription factor can respond to a variety of abiotic stresses, however its function in cotton and the molecular mechanisms of response to salt tolerance remained unclear. In this study, we found that GhVOZ1 is highly expressed in stamen and stem of cotton under normal conditions. The expression of GhVOZ1 increased significantly after 3 h of salt treatment in three-leaf staged upland cotton. Overexpressed transgenic lines of GhVOZ1 in Arabidopsis and upland cotton were treated with salt stress and we found that GhVOZ1 could respond positively to salt stress. GhVOZ1 can regulate Arabidopsis Vacuolar Proton Pump Pyrophosphatase (H+-PPase) gene (AVP1) expression through specific binding to GCGTCTAAAGTACGC site on GhAVP1 promoter, which was examined through Dual-luciferase assay and Electrophoretic mobility shift assay (EMSA). AVP1 expression was significantly increased in Arabidopsis with GhVOZ1 overexpression, while GhAVP1 expression was decreased in virus induced gene silenced (VIGS) cotton plants of GhVOZ1. Knockdown of GhAVP1 expression in cotton plants by VIGS showed decreased superoxide dismutase (SOD) and peroxidase (POD) activities, whereas an increased malondialdehyde (MDA) content and ultimately decreased salt tolerance. The GhVOZ1-AVP1 module could maintain sodium ion homeostasis through cell ion transport and positively regulate the salt tolerance in cotton, providing new ideas and insights for the study of salt tolerance.

Abstract
BACKGROUND The outcome of patients with resectable mucosal melanoma is poor. Toripalimab combined with axitinib has shown impressive results in metastatic mucosal melanoma with an objective response rate of 48.3% and a median progression-free survival of 7.5 months in a phase Ib trial. It was hypothesized that this combination administered in the neoadjuvant setting might induce a pathologic response in resectable mucosal melanoma, so we conducted this trial. PATIENTS AND METHODS This single-arm phase II trial enrolled patients with resectable mucosal melanoma. Patients received toripalimab 3 mg/kg once every 2 weeks (Q2W) plus axitinib 5 mg two times a day (b.i.d.) for 8 weeks as neoadjuvant therapy, then surgery and adjuvant toripalimab 3 mg/kg Q2W starting 2 ± 1weeks after surgery for 44 weeks. The primary endpoint was the pathologic response rate according to the International Neoadjuvant Melanoma Consortium recommendations. RESULTS Between August 2019 and October 2021, 29 patients were enrolled and received treatment, of whom 24 underwent resection. The median follow-up time was 34.2 months (95% confidence interval 20.4-48.0 months). The pathologic response rate was 33.3% (8/24; 4 pathological complete responses and 4 pathological partial responses). The median event-free survival for all patients was 11.1 months (95% confidence interval 5.3-16.9 months). The median overall survival was not reached. Neoadjuvant therapy was tolerable with 8 (27.5%) grade 3-4 treatment-related adverse events and no treatment-related deaths. Tissue samples of 17 patients at baseline and after surgery were collected (5 responders and 12 nonresponders). Multiplex immunohistochemistry demonstrated a significant increase in CD3+ (P = 0.0032) and CD3+CD8+ (P = 0.0038) tumor-infiltrating lymphocytes after neoadjuvant therapy, particularly in pathological responders. CONCLUSIONS Neoadjuvant toripalimab combined with axitinib in resectable mucosal melanoma demonstrated a promising pathologic response rate with significantly increased infiltrating CD3+ and CD3+CD8+ T cells after therapy.

Abstract
Expert systematic review on the choice of conduits for coronary artery bypass grafting: endorsed by the European Association for Cardio-Thoracic Surgery and the Society of Thoracic Surgeons published in 2023 made recommendations for the selection of bypass vessels. The left internal thoracic artery-anterior descending branch anastomosis represents the accepted gold standard. Radial artery could achieve a better long-term patency rate and a reduction in adverse cardiac events compared to the great saphenous vein. Radial artery graft using an open harvesting method should be chosen to graft the target vessel with low competitive coronary flow, with the use of vasodilators for the first year. There was no clear evidence of better patency for the right internal thoracic artery compared to the great saphenous vein. The bilateral internal thoracic artery had better long-term survival compared to great saphenous vein but may be associated with a higher risk of deep sternal wound infection and should be avoided in high-risk patients. The impact of skeletonization of the internal thoracic artery on graft patency and cardiovascular outcomes was unclear. Endoscopic vein harvest reduced the risk of leg wound complications and was associated with reduced long-term patency. The patency of the no-touch great saphenous vein was significantly better than that of conventional great saphenous vein. A significantly higher risk of complications at the harvesting site and no clear evidence of better long-term clinical outcomes were found in the no-touch great saphenous vein compared to the conventional. There was limited data on the use of right gastroepiploic artery and skeletonized harvesting, which should be used to bypass target vessels in patients with low competitive flow.

Abstract
Radiation-induced intestinal injury is a radiation injury of the colon and rectum after radiotherapy for pelvic malignant tumors. This condition affects multiple organs in the pelvis, making treatment challenging. In clinical practice, the most effective protocol is often determined through discussion by a multi-disciplinary team (MDT). However, due to the severity and complexity of radiation enteritis, many patients still experience poor diagnosis and treatment outcomes. Holistic integrative management (HIM) is a rapidly developing concept that has greatly enhanced clinical medicine in recent years. It improves the level of diagnosis, treatment, prevention, and rehabilitation from multiple dimensions of prevention, screening, diagnosis, treatment, and rehabilitation. In the context of radiation-induced intestinal injury, HIM also calls for the implementation of an individualized management system that focuses on the patient as a whole within the healthcare team. From the perspective of HIM, this article introduces some of the latest progress of radiation-induced intestinal injury in recent years.

Abstract
BACKGROUND Phloem protein 2 (PP2) proteins play a vital role in the Phloem-based defense (PBD) and participate in many abiotic and biotic stress. However, research on PP2 proteins in cotton is still lacking. RESULTS A total of 25, 23, 43, and 47 PP2 genes were comprehensively identified and characterized in G.arboretum, G.raimondii, G.barbadense, and G.hirsutum. The whole genome duplication (WGD) and allopolyploidization events play essential roles in the expansion of PP2 genes. The promoter regions of GhPP2 genes contain many cis-acting elements related to abiotic stress and the weighted gene co-expression network analysis (WGCNA) analysis displayed that GhPP2s could be related to salt stress. The qRT-PCR assays further confirmed that GhPP2-33 could be dramatically upregulated during the salt treatment. And the virus-induced gene silencing (VIGS) experiment proved that the silencing of GhPP2-33 could decrease salt tolerance. CONCLUSIONS The results in this study not only offer new perspectives for understanding the evolution of PP2 genes in cotton but also further explore their function under salt stress.

Abstract
Objective: To investigate the experience of patients in the implementation of enhanced recovery after surgery (ERAS) strategy after radical gastrectomy and the factors affecting the treatment experience. Methods: A prospective cohort study was carried out. Patients who were diagnosed with gastric cancer by pathology and underwent radical gastrectomy at the Xijing Digestive Disease Hospital from December 2019 to December 2020 were consecutively enrolled. Those who received emergency surgery, residual gastric cancer surgery, preoperative neoadjuvant chemotherapy, non-curative tumor resection, intraperitoneal metastasis, or other malignant tumors were excluded. Patients' expectation and experience during implementation were investigated by questionnaires. The questionnaire included three main parts: patients' expectation for ERAS, patients' experience during the ERAS implementation, and patients' outcomes within 30 days after discharge. The items on the expectation and experience were ranked from 0 to 10 by patients, which indicated to be unsatisfied/unimportant and satisfied/important respectively. According to their attitudes towards the ERAS strategy, patients were divided into the support group and the reject group. Patients' expectation and experience of hospital stay, and the clinical outcomes within 30 days after discharge were compared between the two groups. Categorical data were reported as number with percentage and the quantitative data were reported as mean with standard deviation, or where appropriate, as the median with interquartile range (Q1, Q3). Categorical data were compared using the Chi-squared test or Fisher's exact test, where appropriate. For continuous data, Student's t test or Mann-Whitney U test were used. Complication was classified according to Clavien-Dindo classification. Results: Of the included 112 patients (88 males and 24 females), aged (57.8±10.0) years, 35 patients (31.3%) were in the support group and 77 (68.7%) in the reject group. Anxiety was detected in 56.2% (63/112) of the patients with score >8. The admission education during the ERAS implementation improved the patients' cognitions of the ERAS strategy [M(Q1, Q3) score: 8 (4, 10) vs. 2 (0, 5), Z=-7.130, P<0.001]. The expected hospital stay of patients was longer than the actual stay [7 (7, 10) days vs. 6 (6, 7) days, Z=-4.800, P<0.001]. During the ERAS implementation, patients had low score in early mobilization [3 (1, 6)] and early oral intake [5 (2.25, 8)]. Fifty-eight (51.8%) patients planned the ERAS implementation at home after discharge, while 32.1% (36/112) preferred to stay in hospital until they felt totally recovered. Compared with the reject group, the support group had shorter expected hospital stay [7 (6, 10) days vs. 10 (7, 15) days, Z=-2.607, P=0.009], and higher expected recovery-efficiency score [9 (8, 10) vs. 7(5, 9), Z=-3.078, P=0.002], lower expected less-pain score [8 (6, 10) vs. 6 (5, 9) days, Z=-1.996, P=0.046], expected faster recovery of physical strength score [8 (6, 10) vs. 6 (4, 9), Z=-2.200, P=0.028] and expected less drainage tube score [8 (8, 10) vs. 8 (5, 10), Z=-2.075, P=0.038]. Worrying about complications (49.1%) and self-recognition of not recovery (46.4%) were the major concerns when assessing the experience toward ERAS. During the follow-up, 105 patients received follow-up calls. There were 57.1% (60/105) of patients who experienced a variety of discomforts after discharge, including pain (28.6%), bloating (20.0%), nausea (12.4%), fatigue (7.6%), and fever (2.9%). Within 30 days after discharge, 6.7% (7/105) of patients developed Clavien-Dindo level I and II operation-associated complications, including poor wound healing, intestinal obstruction, intraperitoneal bleeding, and wound infection, all of which were cured by conservative treatment. There were no complications of level III or above in the whole group after surgery. Compared with the support group, more patients in the reject group reported that they had not yet achieved self-expected recovery when discharged [57.1% (44/77) vs. 22.9% (8/35), χ2=11.372, P<0.001], and expected to return to their daily lives [39.0% (30/77) vs. 8.6% (3/35), χ2=10.693, P<0.001], with statistically significant differences (all P<0.05). Only 52.4% (55/105) of patients returned home to continue rehabilitation, and the remaining patients chose to go to other hospitals to continue their hospitalization after discharge, with a median length of stay of 7 (7, 9) days. Compared with the reject group, the support group had a higher proportion of home rehabilitation [59.7% (12/33) vs. 36.4% (43/72), χ2=4.950, P=0.026], and shorter time of self-perceived postoperative full recovery [14 (10, 20) days vs. 15 (14, 20) days, Z=2.100, P=0.036], with statistically significant differences (all P<0.05). Conclusions: Although ERAS has promoted postoperative rehabilitation while ensuring surgical safety, it has not been unanimously recognized by patients. Adequate rehabilitation education, good analgesia, good physical recovery, and early removal of drainage tubes may improve the patient's experience of ERAS.

Abstract
BACKGROUND No standard of care for mucosal melanoma (MM) in the adjuvant setting has been established. Meanwhile, relapse-free survival (RFS) is only about five months after surgery alone. This phase II trial aimed to compare toripalimab vs. high-dose interferon-α2b (HDI) as an adjuvant therapy for resected MM. PATIENTS AND METHODS From July 2017 to May 2019, 145 patients with resected MM were randomized (1:1) to receive HDI (N = 72) or toripalimab (N = 73) for one year until disease relapse/distant metastasis, unacceptable toxicity, or withdrawal of consent. The primary endpoint was RFS. The secondary endpoints included distant metastasis-free survival (DMFS), overall survival (OS), and safety. RESULTS After a median follow-up of 26.3 months, the numbers of RFS, OS, and DMFS events were 51 vs. 46, 33 vs. 29, and 49 vs. 44 in the toripalimab arm and the HDI arm, respectively. The median RFS were 13.6 (95%CI: 8.31-19.02) months and 13.9 (95%CI: 8.28-19.61) months in the toripalimab arm and HDI arm, respectively. The DMFS was not significantly different between the two arms (HR: 1.00, 95%CI: 0.65-1.54). The median OS was 35.1 months (95%CI: 27.93-NR) in the toripalimab arm, with no significant difference in all-cause death (HR: 1.11, 95% CI: 0.66-1.84) for the two arms. The median sums of the patients' actual infusion doses were 3672 mg and 1054.5 MIU in the toripalimab arm and HDI arm, respectively. The incidence of treatment-emergent adverse events with a grade ≥ 3 was much higher in the HDI arm than in the toripalimab arm (87.5% vs. 27.4%). CONCLUSION Toripalimab showed a similar RFS and a more favorable safety profile than HDI, both better than historical data, suggesting that toripalimab might be the better treatment option. However, additional translational studies and better treatment regimens are still warranted to improve the clinical outcome of MM.

Abstract
BACKGROUND Foxtail millet grain has higher folate content than other cereal crops. However, the folate metabolite content and the expression patterns of folate metabolite-related genes are unknown. RESULTS Liquid chromatography-mass spectrometry was used to investigate 12 folate metabolites in a foxtail millet panicle. The content of total folate and derivatives gradually decreased during panicle development. Polyglutamate 5-formyl-tetrahydrofolate was the major form. Twenty-eight genes involved in the folate metabolic pathway were identified through bioinformatic analysis. These genes in Setaria italica, S. viridis and Zea mays showed genomic collinearity. Phylogenetic analysis revealed that the folate-related genes were closely related among the C4 plants compared to C3 plants. The gene expressions were then studied at three panicle development stages. The gene expression patterns were classified into two groups, namely SiADCL1 and SiGGH as two key enzymes, which are responsible for folate synthesis and degradation; their expression levels were highest at the early panicle development stage, up to 179.11- and 163.88-fold, respectively. Their expression levels had a similar downward trend during panicle development and were significantly positively correlated with the concentration of total folate and folate derivatives. However, SiSHMT3 expression levels were significantly negatively correlated with total folate concentration. CONCLUSION Besides being the major determinants of folate and folate derivatives accumulation, SiADCL1 and SiGGH expression levels are key limiting factors in the foxtail millet panicle. Therefore, SiADCL1 and SiGGH expression levels can be targeted in genetic modification studies to improve folate content in foxtail millet seeds in the future. © 2021 Society of Chemical Industry.

Abstract
Objective: To observe the incidence and treatment of radiation rectal injury complicated with anxiety, depression and somatic symptom disorder. Methods: A cross-sectional survey research method was carried out. Patients with radiation rectal injury managed by members of the editorial board of Chinese Journal of Gastrointestinal Surgery were the subjects of investigation. The inclusion criteria of the survey subjects: (1) patients suffered from pelvic tumors and received pelvic radiotherapy; (2) colonoscopy showed inflammatory reaction or ulcer in the rectum. Exclusion criteria: (1) patient had a history of psycho-somatic disease before radiotherapy; (2) patient was unable to use a smart phone, unable to read and understand the questions in the questionnaire displayed on the phone; (3) patient refused to sign an informed consent form. According to the SOMA self-rating scale, PHQ-15 self-rating scale, GAD-7 and PHQ-9 self-rating scale, the electronic questionnaire of "Psychological Survey of Radiation Proctitis" was designed. The questionnaire was sent to patients with radiation rectal injury managed by the committee through the WeChat group. Observational indicators: (1) radiation rectal injury symptom assessment: using SOMA self-rating scale, radiation rectal injury symptom classification: mild group (≤3 points), moderate group (4-6 points) and severe group (> 6 points); (2) incidence of anxiety, depression and physical disorder: using GAD-7, PHQ-9 and PHQ-15 self-rating scales respectively for assessment; (3) correlation of radiation rectal injury symptom grading with anxiety, depression, and somatic symptom disorder. Results: Seventy-one qualified questionnaires were collected, of which 41 (56.9%) were from Guangzhou. Among the 71 patients, 6 were males and 65 were females; the mean age was (55.7±9.3) years old and 48 patients (67.6%) were less than 60 years old; the median confirmed duration of radiation rectal injury was 2.0 (1.0, 5.0) years. (1) Evaluation of symptoms of radiation rectal injury: 18 cases of mild (25.4%), 27 cases of moderate (38.0%), and 26 cases of severe (36.6%). (2) Incidence of anxiety, depression and somatic disorder: 12 patients (16.9%) without comorbidities; 59 patients (83.1%) with anxiety, depression, or somatic disorder, of whom 2 patients only had anxiety, 1 patient only had depression, 9 only had somatic disorder, 2 had anxiety plus depression, 4 had anxiety plus somatic disorder, 2 had depression plus somatic disorder, and 40 had all three symptoms. (3) correlation of radiation rectal injury grading with anxiety, depression, and somatic symptom disorder: as compared to patients in mild group and moderate group, those in severe group had higher severity of anxiety and somatic symptom disorder (Z=-2.143, P=0.032; Z=-2.045, P=0.041), while there was no statistically significant difference of depression between mild group and moderate group (Z=-1.176, P=0.240). Pearson correlation analysis revealed that radiation rectal injury symptom score was positively correlated with anxiety (r=0.300, P=0.013), depression (r=0.287, P=0.015) and somatic symptom disorder (r=0.344, P=0.003). Conclusions: The incidence of anxiety, depression, and somatic symptom disorder in patients with radiation rectal injury is extremely high. It is necessary to strengthen the diagnosis and treatment of somatic symptom disorder, so as to alleviate the symptoms of patients with pelvic perineum pain and improve the quality of life.

Abstract
The caleosin (CLO) protein family displays calcium-binding properties and plays an important role in the abiotic stress response. Here, a total of 107 CLO genes were identified in 15 plant species, while no CLO genes were detected in two green algal species. Evolutionary analysis revealed that the CLO gene family may have evolved mainly in terrestrial plants and that biological functional differentiation between species and functional expansion within species have occurred. Of these, 56 CLO genes were identified in four cotton species. Collinearity analysis showed that CLO gene family expansion mainly occurred through segmental duplication and whole-genome duplication in cotton. Sequence alignment and phylogenetic analysis showed that the CLO proteins of the four cotton species were mainly divided into two types: H-caleosins (class I) and L-caleosins (class II). Cis-acting element analysis and quantitative RT-PCR (qRT-PCR) suggested that GhCLOs might be regulated by abscisic acid (ABA) and methyl jasmonate (MeJA). Moreover, transcriptome data and qRT-PCR results revealed that GhCLO genes responded to salt and drought stresses. Under salt stress, gene-silenced plants (TRV: GhCLO06) showed obvious yellowing and wilting, higher malondialdehyde (MDA) content accumulation, and significantly lower activities of superoxide dismutase (SOD) and peroxidase (POD), indicating that GhCLO06 plays a positive regulatory role in cotton salt tolerance. In gene-silenced plants (TRV: GhCLO06), ABA-related genes (GhABF2, GhABI5, and GhNAC4) were significantly upregulated after salt stress, suggesting that the regulation of salt tolerance may be related to the ABA signaling pathway. This research provides an important reference for further understanding and analyzing the molecular regulatory mechanism of CLOs for salt tolerance.

Abstract
BRAF inhibitors substantially have impressive clinical efficacy in cutaneous melanoma. However, their role in acral and mucosal melanoma remains unclear. Records were reviewed of patients with metastatic or unresectable BRAF-mutant acral and mucosal melanoma hospitalized and administrated BRAF inhibitors during January 2011 and March 2016. Clinical data were collected to determine PFS, ORR, DCR, OS, and safety. Among 28 acral and 12 mucosal melanoma patients treated with BRAF inhibitors, median PFS were 3.6 (95%CI 3.0-6.4) and 4.4 (95%CI 0.8-12.7) months, median OS were 6.2 (95%CI 6.1-12.1) and 8.2 (95%CI 6.6-19.9) months; ORRs were 38.1% and 20.0%, DCRs were 81.0% and 70.0% in acral and mucosal melanoma, respectively. BRAF inhibitors were well tolerated. The most common adverse effects (AEs) were cutaneous and hematological. Grade 3/4 AEs were relatively rare. In conclusion, BRAF inhibitors have acceptable efficacy and good tolerance in BRAF mutant acral and mucosal melanoma.

Abstract
Objective: To observe the impact of first-line chemotherapy on renal function in patients with unresectable/metastatic upper tract urothelial carcinoma(UTUC). Methods: A total of 222 (130 males and 92 females) unresectable/metastatic upper tract urothelial carcinoma patients were included in the study between January 2005 and May 2017, with age of 29 to 87 (62.4±10.1) years old. The serum creatinine level and estimated glomerular filtration rate (eGFR) were compared before and after first-line chemotherapy. And predictive factors for decreased renal function were analyzed in logistic regression model. Results: After the first-line chemotherapy, the average serum creatinine level increased, with a median changing value of 1.5 μmol/L. Howerver, the eGFR improved, with a median changing value of 0.5 ml·min-1· (1.73 m2)-1, but the differences were not statistically significant (all P>0.05). In 149 patients who were treated with cisplatin-based chemotherapy, the average serum creatinine level increased by 1.31 μmol/L and eGFR improved by 0.14 ml·min-1·(1.73 m2)-1, but the differences were not statistically significant (P>0.05). In multivariate logistic regression model, age more than and equal to 60 years old (OR=0.88, P=0.745) and cisplatin-based chemotherapy (OR=0.95, P=0.893) did not increase the risk of renal dysfunction after first-line chemotherapy. If the time interval between surgery and first-line chemotherapy was more than 1 year, the risk of renal dysfunction due to chemotherapy decreased (OR=0.54, P=0.196). Eastern Cooperative Oncology Group Performance Status (ECOG PS) Scale≥1 (OR=1.81, P=0.131), anemia before treatment (OR=1.14, P=0.764), the cycles of first-line chemotherapy (OR=1.41, P=0.398) may lead to increase the risk of renal dysfunction, but the differences were not statistically significant. However in the patients who accepted nephrectomy, the risk of renal dysfunction after chemotherapy increased, but the difference was still not statistically significant (OR=3.06, P=0.089). Conclusions: First-line chemotherapy, especially the cisplatin-based regimen, had no significant impact on renal function in the patients with UTUC. Nephrectomy maybe a predictive risk factor for decreased renal function after chemotherapy. Adequate assessment of renal function before treatment, hydration and close monitoring during chemotherapy can effectively protect renal function of the patients.

Abstract
The laminated structure of graphene oxide (GO) confers unique interactions with water molecules which may be utilised in a range of applications that require materials with tuneable hygroscopic properties. The precise role of the expandable interlayer spacing and functional groups in GO laminates has not completely been understood to date. Herein, we report the experimental and theoretical investigations on the adsorption and desorption behaviour of water in GO laminates as a function of relative pressure. We observed that GO imparts high water uptake capacity of up to 0.58 gram of water per gram of GO (g g-1), which is significantly higher than silica gel as a conventional desiccant material. More interestingly, the adsorption and desorption kinetics of GO is five times higher than silica gel. The observed extraordinary adsorption/desorption rate can be attributed to the high capillary pressure in GO laminates as well as micro meter sized tunnel-like wrinkles located at the surface.

Abstract
Abstract
Background. Triple negative breast cancer (TNBC) is an aggressive subtype of breast cancers, for which the only standard therapeutics is chemotherapy containing Taxol. However, quite a number of TNBC patients cannot get the expected drug response after paclitaxel treatment and the resistant mechanism has not been clear yet. Other than the traditional “genotype-to-phenotype” means, the high-throughput functional screening, such as CRISPR-CAS9 library, selects genes with the phenotype of interest. Here, we combine the novel screening model with the drug-resistant genotype to explore the decisive role in paclitaxel effect.
Methods. Breast cancer cell line MDA-MB-231(231WT) was treated by paclitaxel from 1ug/ml to 5ug/ml to establish a paclitaxel-resistant cell type (231PTX) for transcriptome sequencing. Genome-scale CRISPR-Cas9 sgRNA library was made into lentivirus to affect MDA-MB-231 cells expressed Cas9 protein (231cas9). Then 231cas9-sgRNA was treated by low dose of paclitaxel for 14 days and was read by next generation sequencing. RNA sequencing data was processed to TPM values and sgRNA data to gene ranking and p value. The threshold of “231PTX TPM/231WT TPM” was above 2 or below 1/2 and the gene p value was smaller than 0.05. Biological technology applied in this study includes western blot (WB), immunofluorescence (IF), real time PCR and cell proliferation assay. In vivo, 20 balb/c mouse were injected MDA-MB-231 in situ for tumor formation and were treated with paclitaxel/normal saline for six times.
Results. Crosstalk between these two sequencing data had result of 124 genes related to paclitaxel resistance (fold change> 2 and p value<0.05 compared Day 14 treated group to Day 14 untreated group) and 18 genes related to paclitaxel sensitivity (fold change< 1/2 and p value<0.05 compared Day 14 untreated group to Day 14 treated group). Considering clinical prognosis and gene information, six paclitaxel resistant candidates and four paclitaxel sensitive candidates were chosen for further research. Eight (STRA6, BIRC3, MTUS1, HDAC9, ADAM28, S1PR5, TNNC1, ZKSCAN7) of ten candidates displayed consistent phenotypes with sequencing results including mRNA expression and the cellular proliferation in paclitaxel treatment. HDAC9 is a histone deacetylation gene that is likely to be a paclitaxel resistant gene. Knockout HDAC9 (231H9 KO) contributed to nearly 2-fold decrease IC50 value (1.7nM versus 3.7nM, p value<0.01). Confocal microscopy observed the formation of multiple spindle foci in the paclitaxel treated 231H9 KO cells. After treatment with paclitaxel, the mark of polymerized tubulin, acetylation tubulin and the mark of cell cycle G2/M, cyclin B1 were notably increased when HDAC9 knockout in both MD-MB1-231 and BT-100 cell lines. In vivo assays found that HDAC9 knockout induced the declined tumorigenesis and more sensitive breast tumors to paclitaxel.
Conclusions.Combined Genome-scale CRISPR-Cas9 knockout screening with transcriptome sequencing is efficient to investigate potent drug targets. In vitro assays suggest that HDAC9 is conductive to paclitaxel resistance in TNBC cells. In vivo results imply inhibition HDAC9 may beneficial to paclitaxel therapeutic response.

Abstract
Abnormal lipid-metabolism and elevated oxidative stress are the familiar complications of diabetic mellitus. Regulated lipid-metabolism and decreased oxidative stress have become the key indices to cure diabetic complications. The activities of broth extract (TBE) and mycelia polysaccharides (TMP) of Tremella aurantialba, which is one of the best-known multipurpose medicinal fungi in China, were studied using alloxan-induced diabetic rats. TBE contains saponins, while TMP contains polysaccharides. Both TBE and TMP could reduce the blood glucose levels of diabetic rats; TBE had stronger abilities to reduce the levels of total cholesterol and total triglyceride in serum, those of malondialdehyde, and enhance the activities of superoxide dismutase and glutathione reductase in different tissues of diabetic rats (P < 0.01). TBE had slightly stronger abilities to enhance the total antioxidant capability, catalase, and glutathione peroxidase in different tissues of diabetic rats, but no significant difference was found between TBE and TMP groups. All these results indicated that TBE was more capable of regulating lipid-metabolism and decreasing oxidative stress.

Abstract
An Acinetobacter strain, given the code name LCH001 and having the potential to be an endophytic antagonist, has been isolated from healthy stems of the plant Cinnamomum camphora (L.) Presl, guided by an in vitro screening technique. The bacterium inhibited the growth of several phytopathogenic fungi such as Cryphonectria parasitica, Glomerella glycines, Phytophthora capsici, Fusarium graminearum, Botrytis cinerea, and Rhizoctonia solani. Biochemical, physiological, and 16S rDNA sequence analysis proved that it is Acinetobacter baumannii. When the filtrate from the fermentation broth of strain LCH001 was tested in vitro and in vivo, it showed strong growth inhibition against several phytopathogens including P. capsici, F. graminearum, and R. solani, indicating that suppression of the growth of the fungi was due to the presence of antifungal compounds in the culture broth. Moreover, the antifungal activity of the culture filtrate was significantly correlated with the cell growth of strain LCH001. The active metabolites in the filtrate were relatively thermally stable, but were sensitive to acidic conditions. Three antifungal compounds were isolated from the culture broth by absorption onto macropore resin, ethanol extraction, chromatography on silica gel or LH-20 columns, and crystallization. The structures of the bioactive compounds were identified by spectroscopic methods as isomers of iturin A, namely, iturin A2, iturin A3, and iturin A6. The characterization of an unusual endophytic bacterial strain LCH001 and its bioactive components may provide an alternative resource for the biocontrol of plant diseases.

Abstract
Silicate bacteria are generally placed in the species Bacillus circulans and are widely used in biological fertilisers and biological leaching. The bacteria can form conspicuous amounts of extracellular polysaccharides in nitrogen-free media or in the presence of substrates with large C/N ratios. Using high performance liquid chromatography, we have shown that B. circulans produced a new peak/compound when induced with the plant-to-bacteria signal molecule genistein. This material co-eluted with the lipo-chitooligosaccharide (Nod Bj-V (C18:1, MeFuc)) of Bradyrhizobium japonicum. This compound exhibited root hair deformation activity on soybean, which is characteristic of lipo-chitooligosaccharides (LCOs). We propose that this might be an LCO or closely related compound with similar biological activity.

Abstract
OBJECTIVES Ethnographic literature on inner-city life argues that adolescents react to their uncertain (and objectively bleak) future by abandoning hope; this, in turn, leads them to engage in risk behaviors, including violence, with considerable frequency. This study empirically measures the pervasiveness of hopelessness and uncertainty about the future among inner-city adolescents and documents the link between hopelessness, uncertainty, and risk behavior. METHODS We surveyed a sample of 583 adolescents (aged 9-19) living in public housing in Huntsville, AL; this constitutes 80% of the eligible population. Each participant in the survey received $10. Their responses yielded empirical distributions for hopelessness, uncertainty about the future, and four violent behaviors. Using OLS regression, we examined the effect of hopelessness on these violent behaviors. RESULTS Hopelessness about the future was relatively rare, affecting only 20-30% of the respondents. However, it was a strong predictor of fighting and carrying a knife for females, and of carrying a knife, carrying a gun, and pulling a knife or gun on someone else for males. Uncertainty about the future was more prevalent, but unrelated to the violent behaviors. CONCLUSIONS These results suggest that the conclusions of the ethnographic literature are only partially valid: While hopelessness is, in fact, strongly related to risk behavior, it is not nearly so prevalent as is generally assumed.

Abstract
OBJECTIVE In order to study the site of nasal parameters, nasal minimal cross-sectional area (NMCA), nasal cavity volume (NCV), nasal resistance (NR) and the relations among them. METHOD 276 younger adult of normal Cantonese were tested by ECCOVISION acoustic rhinometer. RESULT The results were as follows: 72.95% NMCA in subjects are positioned at internal nostril. The distance from the position of NMCA to the nostril is 1.36 +/- 0.53 cm in male, and 1.06 +/- 0.46 cm in female. There was no difference in NMCA, NCV and NR between male and female. There was significant relationship between the NR and NMCA. There was relationship between the NR and NCV, and there was little relationship between the NR and DCAN. CONCLUSION Acoustic rhinometry is a new objective rhinometric method, but different race must have its standard respectively.

Abstract
OBJECTIVE To study the mechanism of preventing the recurrence of bladder carcinoma by intravesical instillation of BCG plus IL-2. METHOD Intravesical instillation of BCG or BCG plus IL-2 were carried out in the bladder transitional cell carcinoma patients undergoing surgical operation (16, 19 cases respectively). RESULT They were followed up for 14-22 months. The recurrence rates were 31.25% and 21.05% respectively. At 6 weeks after the instillation of IL-2 plus BCG, the peripheral blood NKCF activity was increased significantly and there was a significant positive correlation between the activities of NKCF and IL-2. CONCLUSION The intravesical instillation of IL-2 plus BCG is clearly superior to only BCG in preventing recurrence of bladder carcinoma. There may be immuno-enhancement and immuno-synergism.

Abstract
As the physiologic roles for the different classes of aldehyde dehydrogenase (ALDH) enzymes are elucidated, the identification of specific, reversible inhibitors becomes of great pharmacologic interest. Previous structure-function studies identified dialkylamino substituted benzaldehyde compounds as a novel class of reversible inhibitors of class I ALDH. To examine further structural requirements for inhibition, we tested a series of 4-(N,N-dialkylamino)benzaldehyde analogs as inhibitors of propanal oxidation by mouse liver and human erythrocyte class I ALDH. 4-(N,N-dipropylamino)benzaldehyde (DPAB) was identified as the most potent, reversible inhibitor of propanal oxidation by class I ALDH in spectrophotometric enzyme assays. In kinetic studies, DPAB showed mixed-type inhibition with respect to the aldehyde substrates propanal, phenylacetaldehyde, benzaldehyde, and aldophosphamide. DPAB exhibited uncompetitive inhibition with respect to the cofactor NAD. Inhibition constants (Ki) for DPAB, estimated from Dixon plots, were 10 nM (propanal) and 77 nM (phenylacetaldehyde) for mouse ALDH and 3 nM (propanal) and 70 nM (phenylacetaldehyde) for human ALDH. These Ki values are 100-fold lower than those reported for class I specific inhibitors. At low (< 1 microM) DPAB concentrations, inhibition of propanal and aldophosphamide oxidation was > 75%, whereas inhibition of benzaldehyde (32%) and phenylacetaldehyde (19%) oxidation was reduced markedly. These results indicate that DPAB exhibits potent, reversible inhibition of mouse and human class I ALDH. The degree of inhibition was highly dependent on the structure of the aldehyde substrate.
