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
OBJECTIVE Macrolide antibiotics are often used to prevent infection and inflammation after functional endoscopic sinus surgery for the treatment of chronic rhinosinusitis (CRS). The purpose of this study was to investigate the anti-inflammatory and antibacterial effects of the clarithromycin-loaded poly(-lactide) (CLA-PLLA) membrane and its mechanism. STUDY DESIGN Randomized controlled trial. SETTING Animal Experiment Center. METHODS We compared the difference between poly(l-lactide) (PLLA) and CLA-PLLA membranes by observing the morphology of fibrous scaffolds, measuring water contact angle, tensile strength, and drug release capacity, and evaluating the antimicrobial activity of CLA-PLLA. Twenty-four rabbits were divided into a PLLA group and a CLA-PLLA group after establishing CRS models. Another 5 normal rabbits comprised the control group. After 3 months, we placed the PLLA membrane in the nasal cavity of the PLLA group and the CLA-PLLA membrane in the CLA-PLLA group. Then, 14 days later, we evaluated the histological and ultrastructural changes in the sinus mucosa, protein, and messenger RNA (mRNA) levels of interleukin (IL)-4, IL-8, tumor necrosis factor-α, transforming growth factor-β1, α-smooth muscle actin, and type I collagen. RESULTS The CLA-PLLA membrane showed no significant difference in physical performance to the PLLA membrane, which continuously released 95% of the clarithromycin (CLA) for 2 months. The CLA-PLLA membrane had significant bacteriostatic properties that can improve the morphology of mucosal tissues, and inhibit protein and mRNA expression of inflammatory cytokines. In addition, CLA-PLLA also inhibited the expression of fibrosis-associated marker molecules. CONCLUSION The CLA-PLLA membrane released CLA slowly and continuously, providing antibacterial, anti-inflammatory, and antifibrotic effects in a rabbit model of postoperative CRS.

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
Objective Based on post-operative PSA at 6th week (PSA6w) after radical prostatectomy to establish an optimal model for predicting natural biochemical recurrence (BCR). Methods A total of 742 patients with post-operative PSA6w from PC-follow database, between January 2003 and October 2022, were included. All the patients had not received any hormone therapy and radiotherapy before operation and BCR. Of these patients, 588 cases operated by one surgeon were enrolled for modelling and another 154 cases operated by other surgeons were for external validation. After screened by Cox regression, the post-operative PSA6w, pathological stage, Gleason Grade and positive surgical margins were adopted for modelling. The R software was used to plot the nomogram of the prediction model for BCR. C-index and calibration curve were calculated to evaluate the new model. Finally, integrated discrimination improvement was adopted to evaluate the prediction performances of the new nomogram model and the classical Kattan nomogram. Results The C-index of the new model was 0.871 (95% CI: 0.830-0.912). The calibration curve of the new model demonstrated superior consistency between the predicted and actual value. The C-index of the external validation group was 0.850 (95% CI: 0.742-0.958), which demonstrated perfect universality. The integrated discrimination improvement showed a 12.61% improvement in prediction performance over that of the classical Kattan nomogram (P < 0.01). Based on the new nomogram, patients were divided to high and low BCR group with a 3 year BCR-free cutoff probability as 74.72%. Low-risk patients, accounting for 77.89% of the patients, have no need to follow up frequently with a false-negative rate only 5.24%, which will save medical resources to a large extent. Conclusion Post-operative PSA6w is a sensitive risk biomarker for early natural BCR. The new nomogram model could predict BCR probability with a higher accuracy and will further simplify the clinical follow-up strategies.

Abstract
BACKGROUND Biomarkers of DNA damage repair deficiency provide opportunities for personalized treatment with immunotherapy. However, there is limited research on the immune microenvironment of adeno-neuroendocrine prostate cancer (NEPC). In this study, we aimed to assess and describe the comprehensive clinicopathological manifestations of NEPC to improve diagnosis and predict prognosis. METHODS A retrospective medical record review of 66 patients with prostate cancer (PCa) was performed. PCa samples from the 66 patients were analyzed using immunohistochemical staining for the detection of chromogranin, neural cell adhesion molecule 1, and synaptophysin. For tumor-associated immune microenvironment analysis, PD-L1, CD3, and CD8 were labeled in tissue slides. The effect of clinicopathological factors on the survival of patients with Adeno-NEPC was analyzed. RESULTS Twenty patients presented with adeno-NEPC, whereas 46 presented with adeno-PCa. The median age of patients at PCa diagnosis was 67.86 ± 7.05 years (68.65 ± 7.23 years, adeno-NEPC; 67.52 ± 7.02 years, adeno-PCa). Eleven patients with adeno-NEPC underwent prostatectomy, whereas nine received primary androgen deprivation therapy (ADT). Additionally, 30 patients with adeno-PCa underwent prostatectomy, whereas 16 (34.8%) received primary ADT. There was a significant difference in overall survival between patients with adeno-NEPC and those with adeno-PCa (46.0 months vs. 65.0 months). There was also a significant difference in time from prostatectomy to biochemical recurrence between the groups of patients who underwent prostatectomy. Prostatectomy and normal lactate dehydrogenase levels were clinical factors that were significantly associated with better outcomes in patients with adeno-NEPC. Metastatic adeno-NEPC was associated with a higher programmed death ligand 1 (PD-L1) score (2-4) than localized PCa. The data showed that PD-L1 expression in adeno-NEPC may be negatively associated with that in CD8+ T cells. CONCLUSIONS Our study revealed clinicopathological manifestations of adeno-NEPC and some possible predictive factors significantly associated with better outcomes in patients with adeno-NEPC. These findings might be beneficial in the development of diagnostic strategies and customized treatment plans.

Abstract
OBJECTIVE To explore the pathological characteristics and significance of RET proto-oncogene screening in multiple endocrine neoplasia type 2A (MEN2A) with cutaneous lichen amyloidosis (CLA). METHODS Clinical data of 51 members from 7 unrelated pedigrees of MEN2A-CLA were collected. Systemic clinical investigations including biochemical testing, imaging examination, germline RET variant screening and histopathological examination were carried out. RESULTS RET gene variants were detected in 28 patients with MEN2A (C634G/F/R/S/W and C611Y) including 12 males and 16 females, with the mean age of diagnosis being (41.1 ± 18.3) years old, which were consistent with their clinical manifestations. The incidence of medullary thyroid carcinoma (MTC), pheochromocytoma (PHEO), hyperparathyroidism (HPTH) and CLA among 28 MEN2A patients were 89.3%, 28.6%, 7.1% and 28.6%, respectively. Comparison of the incidence of MTC/PHEO/HPTH and CLA between C611Y and C634G/F/R/S/W, only PHEO and CLA in C611Y were lower than those in C634G/F/R/S/W (P < 0.05; P < 0.05). Among 8 patients with CLA, the male to female ratio was 2 : 6. The clinical features included pruritus in the interscapular region and presence of dry, thickened, scaly, brown pigment, clustered or desquamate-like plaques. The mean onset age of CLA [(18.4 ± 4.6) years] versus the mean age at diagnosis of CLA or MEN2A were significantly different (P < 0.001; P < 0.001). CONCLUSION MEN2A-CLA may be the early clinical manifestation of MEN2A and most frequently occurred along with RET-C634 variant. To facilitate the recognition of MEN2A-CLA, to combine family investigation and screening of RET variant are helpful for early diagnosis and standardized treatment, which can improve the long-term outcome of MEN2A-specific tumors.

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
Neuroendocrine prostate cancer (NEPC) is a lethal subtype of prostate cancer, with a 10% five-year survival rate. However, little is known about its origin and the mechanisms governing its emergence. Our study characterized ADPC and NEPC in prostate tumors from 7 patients using scRNA-seq. First, we identified two NEPC gene expression signatures representing different phases of trans-differentiation. New marker genes we identified may be used for clinical diagnosis. Second, integrative analyses combining expression and subclonal architecture revealed different paths by which NEPC diverges from the original ADPC, either directly from treatment-naïve tumor cells or from specific intermediate states of treatment-resistance. Third, we inferred a hierarchical transcription factor (TF) network underlying the progression, which involves constitutive regulation by ASCL1, FOXA2, and selective regulation by NKX2-2, POU3F2, and SOX2. Together, these results defined the complex expression profiles and advanced our understanding of the genetic and transcriptomic mechanisms leading to NEPC differentiation. Single-cell RNA sequencing revealed two distinct transcriptional programs of NEPC Cell-level clonal evolution analysis extended the divergent model of ADPC to NEPC Screening of NEPC-specific transcription factors through network-based approaches

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
Small cell carcinoma (SCC)/neuroendocrine prostate cancer (NEPC) is a rare and highly aggressive subtype of prostate cancer associated with an AR(androgen receptor)-null phenotype and visceral metastases. This study presents a 44-year-old man originally diagnosed with metastatic hormone-sensitive prostatic adenocarcinoma. After 6-month androgen deprivation therapy (ADT) combined with docetaxel, the patient developed paraplegia. Laminectomy was performed, and a thoracic vertebral biopsy revealed neuroendocrine differentiation and mixed adenocarcinoma. The patient developed liver metastases and experienced stable disease for 4 months following etoposide combined with cisplatin and pembrolizumab. Seminal vesicle biopsy after chemotherapy revealed small-cell cancer. The prostate biopsy specimen also indicated pure SCC. We witnessed the dynamic evolution from pure adenocarcinoma to fully differentiated SCC, leading to obstruction and death. In addition, whole-exome sequencing was performed on both biopsy specimens of the thoracic vertebra at the beginning of castration resistance and that of seminal vesicle after multiple lines of treatment failure. Utilizing phylogenetic reconstruction, we observed that both samples shared a common ancestor clone harboring aberrations in the TP53, RB1, and NF2 genes. We also discovered that driver events in the private subclones of both samples, such as alterations in CDC27 and RUNX1, might have played a significant role in tumor progression or even neuroendocrine differentiation. Tumor biopsy and IHC assessment must be repeated at different stages of progression, because of intrapatient spatial and temporal heterogeneity of adenocarcinoma versus SCC/NEPC. Although, typical treatments including ADT, docetaxel, etoposide, cisplatin, and pembrolizumab provided temporary response, the patient still had a poor prognosis.

Abstract
Purpose Through an observational study to present a new approach for obtaining high-quality samples for the targeted therapy of prostate cancer. Patients and Methods Parallel biopsy, which was defined as collecting the tissue from the same site by two biopsies, was performed on patients with elevated PSA. Each tissue was stained by ink to identify the pathological characteristics, including Gleason score and tumor tissue ratio. Kendall tau-b test and intraclass correlation coefficient test were used to compare the consistency between each paired sample. Then, based on the pathology of the biopsies, high-quality tissues would be selected for sequencing, and PyClone model was used to track the clonal evolution. Results In total, 252 pairs of biopsies were collected. The consistency of Gleason score between each paired biopsy is 0.777 (p<0.01), and the consistency of tumor tissue ratio is 0.853 (p<0.01). With the application of parallel biopsy, on average five nonsynonymous mutations could be identified in patients with castration-resistant prostate cancer. Six out of eight had at least one biology-relevant alteration in patients, guiding further treatment. Meanwhile, clonal evolution was constructed to investigate the progress of tumor. Conclusion Parallel biopsy is a reliable approach to collect high-quality tissue and shows potential application in precision medicine.

Abstract
BACKGROUND Endoscopic sinus surgery (ESS) is used to treat chronic rhinosinusitis. However, nasal adhesions often develop postoperatively, triggered by chronic inflammation and local fibrosis. A poly L-lactide (PLLA) electrospun microfibrous membrane is a functional biodegradable material that can be placed on the wound surface to protect the wound and prevent adhesions. METHODS We divided 24 rabbits randomly into 2 groups, a control operation group (group A) and an operation+PLLA placement group (group B). We investigated the anti-fibrotic effects of the topical biomaterial after sinus surgery. We placed PLLA fibrous membranes in the sinus cavity of group B rabbits after sinus surgery, and then evaluated changes in the mucosa and in the levels of collagen fibers, interleukin 4 (IL-4), IL-8, tumor necrosis factor α (TNF-α), transforming growth factor β1 (TGF-β1), α-smooth muscle actin (α-SMA), and collagen I (Col I), using morphological and molecular biological methods. RESULTS PLLA fibrous membranes did not inhibit the synthesis of messenger RNAs (mRNAs) encoding IL-4, IL-8, or TNF-α, or the protein levels, indicating that the membrane did not have an anti-inflammatory effect. However, the membrane inhibited the synthesis of mRNAs encoding TGF-β1, α-SMA, and Col I, and reduced collagen production. Thus, the nanostructured membrane inhibited fibroblast proliferation. CONCLUSION The PLLA membrane had anti-fibrotic effects, and may be used to prevent fibrosis and adhesions after ESS in human patients.

Abstract
Prostate cancer is the second most common cancer in men worldwide1. Over the past decade, large-scale integrative genomics efforts have enhanced our understanding of this disease by characterizing its genetic and epigenetic landscape in thousands of patients2,3. However, most tumours profiled in these studies were obtained from patients from Western populations. Here we produced and analysed whole-genome, whole-transcriptome and DNA methylation data for 208 pairs of tumour tissue samples and matched healthy control tissue from Chinese patients with primary prostate cancer. Systematic comparison with published data from 2,554 prostate tumours revealed that the genomic alteration signatures in Chinese patients were markedly distinct from those of Western cohorts: specifically, 41% of tumours contained mutations in FOXA1 and 18% each had deletions in ZNF292 and CHD1. Alterations of the genome and epigenome were correlated and were predictive of disease phenotype and progression. Coding and noncoding mutations, as well as epimutations, converged on pathways that are important for prostate cancer, providing insights into this devastating disease. These discoveries underscore the importance of including population context in constructing comprehensive genomic maps for disease.

Abstract
Objective To evaluate the safety profile and short-term functional outcome of sustainable functional urethral reconstruction (SFUR) in robotic-assisted radical prostatectomy (RARP). Methods One hundred and sixty-two consecutive prostate cancer patients who underwent RARP were retrospectively analyzed, in which 53 had undergone SFUR while the other 109 had undergone conventional RARP procedures. Immediate, 2-week, 1-month and 3-month continence recovery and other perioperative data were compared to evaluate short-term surgical and functional outcome. Results The median age was 68 and 67 years in the experimental group and control group, respectively (p=0.206), with a median prostate-specific antigen (PSA) of 13.6 ng/mL (interquartile range [IQR], 8.46-27.32 ng/mL) in the experimental group and 13.84 ng/mL (IQR, 9.12-26.80 ng/mL) in control group (p=0.846). Immediate, 2-week, 1-month and 3-month continence recovery rates between the groups were 34.0% vs. 3.7%, 50.9% vs. 14.7%, 62.3% vs. 27.5%, and 79.2% vs. 63.3% (all p<0.05). The morphological changes made by the new reconstruction technique were maintained on magnetic resonance imaging (MRI) 3 months postoperatively. Nerve-sparing procedures and adoption of the new reconstruction technique were significantly relevant to continence recovery on logistics regression model (p<0.001). Conclusions SFUR is a safe and easy-to-handle modification that may contribute to early continence return for RARP. Long-term follow-up and prospective studies are required to further evaluate its value in postoperative quality-of-life improvement.

Abstract
Objectives To summarize the experience of the first 500 robot-assisted laparoscopic radical prostatectomy (RALP) cases by one surgeon and analyze the influencing factors of functional and oncological outcomes. Methods Between April 2012 and October 2017, 500 patients who underwent RALP were included and divided sequentially into five equal groups. Patients’ preoperative, perioperative and postoperative outcomes were analyzed and evaluated, and the Kruskal-Wallis test was used to analyze and compare the effect of surgeon experience by case. Results There is a statistically significant reduction in operative time, intraoperative estimated blood loss and postoperative hospital stay time (all p<0.001) with the increased experience. The results show that experience was the most important influencing factor in both operative time and blood loss. Pelvic lymph node dissection (PLND) might increase the operative time. The total positive surgical margin (PSM) rate was 21.8%. The PSM rate in pT3 tumors was significantly higher than that in pT2 tumors (12.0% vs. 37.1%, p<0.001). The 5-year biochemical recurrence (BCR)-free rate was 70.8%. The results of Cox regression showed that preoperative prostate-specific antigen (PSA), postoperative Gleason score (GS), and pathologic T stage were independent risk factors for BCR. Conclusion After approximately 200 cases, the surgeon reached a plateau for RALP, but the outcomes could still improve after more cases. The surgeon's experience was the most important influencing factor for both operative time and blood loss. PSM rate was mainly determined by tumor stage rather than by operation experience.

Abstract
Testicular cancer is one of the few tumor types that have not yet benefited from targeted therapy. Still no new active agents for treating this cancer have been identified over the past 15 years. Once patients are refractory to cisplatin-based chemotherapy, they will be expected to die from testicular cancer. This report describes a 21-year-old man who was refractory to chemotherapy and immunotherapy. Whole exome sequencing and low-depth whole genome sequencing confirmed the KRAS gene amplification, which may lead to the tumor cells' progression and proliferation. After discussion at the molecular tumor board, the patient was offered paclitaxel, carboplatin, and sorafenib (CPS) based on a phase III clinical trial of melanoma with KRAS gene copy gains. After treatment with CPS, the patient achieved excellent curative effects. Because of a nearly 50% frequency of KRAS amplification in chemotherapy-refractory testicular germ cells, CPS regimen may provide a new therapy, but it still warrants further validation in clinical studies. KEY POINTS: Chemotherapy-refractory testicular cancer has a very poor prognosis resulting in a lack of effective targeted therapies. KRAS gene amplification occurs in nearly 20% of testicular cancer and 50% of chemotherapy-refractory testicular cancer. KRAS amplification may activate the MAPK signaling pathway, and inhibition of MAPK by sorafenib combined with paclitaxel and carboplatin could be a viable option based on a phase III clinical trial of melanoma.To the authors' knowledge, this is the first report of response to sorafenib-based combination targeted therapy in a patient with chemotherapy-refractory testicular cancer.Clinical genomic profiling can confirm copy number variation of testicular cancer and provide insights on therapeutic options.

Abstract
Purpose: Palliative transurethral resection of the prostate (pTURP) in metastatic prostate cancer (mPCa) is reported to be rarely applied in clinics. We prospectively evaluated the ability of pTURP to achieve tumor control in patients with mPCa. Patients and Methods: A prospective study of patients with mPCa from 2011 to 2018 was conducted. The patients were divided into two groups: a pTURP + androgen deprivation therapy (ADT) group and an ADT group. Castration-resistant prostate cancer (CRPC)-free survival and cancer-specific survival (CSS) were analyzed as research endpoints between the groups using a Kaplan-Meier estimator. Results: A total of 188 patients with mPCa were enrolled in the study from our center, of which 110 patients were in the pTURP + ADT group, and 78 patients were in the ADT group. The basic clinical characteristics were comparable between the groups. There were no reoperations or severe complications in the pTURP + ADT group. The median follow-up was 29 months. The median CRPC-free survival was significantly increased when the 7-month prostate-specific antigen (PSA) was <4 ng/mL (34 vs 6, p < 0.01) and bone metastasis was ≤5 (25 vs 10, p < 0.01) but not in the pTURP + ADT group (16 vs 12, p = 0.267). The 3-year CSS was higher in the pTURP + ADT group than that in the ADT group (95.9% vs 64.9%, p = 0.004), as well as when the 7-month PSA was <4 ng/mL compared to ≥4 ng/mL (90.7% vs 36.6%, p < 0.01) and when bone metastasis was ≤5 compared to >5 (82.2% vs 63.2%, p < 0.01). In subgroup analysis, pTURP + ADT could significantly improve patients' CSS when PSA ≥65 ng/mL, Gleason Score (GS) ≥8, and bone metastasis ≤5. Conclusions: We used our center-based cancer database to analyze survival in patients with mPCa undergoing pTURP. In the study population, pTURP + ADT was indicated to benefit CSS and shown to be safe. Moreover, we suggest that mPCa patients with PSA ≥65 ng/mL, GS ≥8, and bone metastasis ≤5 may perform pTURP before ADT.

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.

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.
