Abstract
Objective: To explore the efficacy of immune checkpoint inhibitors combined with adjuvant chemotherapy in patients with phase III gastric cancer and esophagogastric junction cancer. Methods: This study used a retrospective cohort study method based on real-world data. Clinical data of 403 patients with stage III gastric/esophagogastric junction cancer who underwent gastrectomy followed by adjuvant therapy in the Department of Gastric Surgery at Sun Yat-sen University Cancer Center from January 2020 to December 2023 were retrospectively collected. The study cohort comprised 147 (36.5%) patients with stage IIIA, 130 (32.3%) with stage IIIB, and 126 (31.3%) with stage IIIC gastric/esophagogastric junction cancer. Of them, 15 (3.7%) were HER-2 positive, 25 (6.2%) dMMR, and 22 (5.5%) patients Epstein-Barr virus encoding RNA (EBER) positive. Based on treatment plans, the patients were divided into immune checkpoint inhibitor combined with chemotherapy group (immune therapy group, n=110, 71 males and 39 females, median age 59 years old) and chemotherapy alone group (chemotherapy group, n=293, 186 males and 107 females, median age 60 years old). All patients in the immunotherapy group received immune checkpoint inhibitors targeting the programmed cell death protein-1 (PD-1) and its ligand (PD-L1). Of them, 85 received pembrolizumab, 10 received sintilimab, 8 received tislelizumab, 4 received camrelizumab, 2 received toripalimab, and 1 received pabocizumab. The adjuvant chemotherapy regimens used among the chemotherapy alone group includes SOX regimen (132 cases), XELOX (102 cases), S-1 monotherapy (44 cases), and other regimens (15 cases). The 3-year DFS rate of the two groups was compared, and subgroup analysis was conducted based on different ages, molecular phenotypes, pTNM staging, extranodal infiltration, and tumor length. Results: The median follow-up was 20.5 months (range 3.1~46.3), with a 3-year overall DFS rate of 61.4% for the entire 403 patients. The 3-year DFS rate for the immunotherapy group was 82.7%, higher than the chemotherapy alone group (58.8%), with a statistically significant difference (P=0.021). Multivariate analysis showed that postoperative immunotherapy was a protective factor for DFS (HR=0.352, 95%CI: 0.180~0.685). Subgroup analysis showed that stage IIIC (HR=0.416, 95%CI: 0.184~0.940), aged ≥60 years (HR=0.336, 95%CI: 0.121~0.934) and extranodal invasion (HR=0.378, 95%CI: 0.170~0.839) were associated with benefit from the combined immune adjuvant chemotherapy, while no association was observed for MMR, HER-2 or EBER status. Conclusion: Stage III gastric/esophagogastric junction cancer patients may benefite from postoperative immune checkpoint inhibitor combined with adjuvant chemotherapy in real-world settings.

Abstract
BACKGROUND Hemorrhoids are among the most common and frequently encountered chronic anorectal diseases in anorectal surgery. They are venous clusters formed by congestion, expansion, and flexion of the venous plexus in the lower part of the rectum. Mixed hemorrhoids bleed easily and recurrently, and this can result in severe anemia. Hence, they may have a negative effect on the health of the patient and surgical treatment is required. Milligan-Morgan hemorrhoidectomy has been widely used since 1937 for the treatment of grade III and IV hemorrhoids. However, most patients experience different degrees of postoperative pain that may cause anxiety. AIM To assess the factors influencing pain scores and quality of life (QoL) in patients with mixed hemorrhoids post-surgery. METHODS The clinical data of patients with mixed hemorrhoids who underwent Milligan-Morgan hemorrhoidectomy were collected retrospectively. The basic characteristics of the enrolled patients with mixed hemorrhoids were recorded, and based on the Goligher clinical grading system, the hemorrhoids were classified as grades III or IV. The endpoint of this study was the disappearance of pain in all patients. Quantitative data were presented as mean ± SD, such as age, pain score, and QoL score. Student's t-test was used to compare the groups. RESULTS A total of 164 patients were enrolled. The distribution of the visual analog scale pain scores of all patients at 3, 7, 14 and 28 d after surgery showed that post-surgery pain was significantly reduced with the passage of time. Fourteen days after the operation, the pain had completely disappeared in some patients. Twenty-eight days after the surgery, none of the patients experienced any pain. Comparing the World Health Organization Quality of Life - BREF self-reporting questionnaire scores of patients between 14 and 28 d after surgery, we observed that the quality-of-life scores of the patients post-surgery had significantly improved. There were six items that were compared at 14- and 28-d post-surgery. The mean QoL score 28 d after surgery (4.79 ± 0.46) was higher than that at 14 d post-surgery (3.79 ± 0.57). The mean health condition score 28 d after surgery (4.80 ± 0.41) was also higher than that at 14 d post-surgery (4.01 ± 0.62). The mean physical health score 28 d after surgery (32.10 ± 2.96) was significantly higher than that at 14 d post-surgery (23.41 ± 2.85). The mean psychological health score 28 d after surgery (27.22 ± 1.62) was significantly higher than that at 14 d post-surgery (21.37 ± 1.70). The mean social relations score 28 d after surgery (12.21 ± 1.59) was significantly higher than that at 14 d post-surgery (6.32 ± 1.66). The mean surrounding environment score 28 d after surgery (37.13 ± 2.88) was significantly higher than that at 14 d post-surgery (28.42 ± 2.86). The differences in quality-of-life scores at day 14 and day 28 post-surgery were observed to be statistically significant (P < 0.001). CONCLUSION Milligan-Morgan hemorrhoidectomy can significantly improve the postoperative QoL of patients. Age, sex, and the number of surgical resections were important factors influencing Milligan-Morgan hemorrhoidectomy.

Abstract
The phosphate-coordination triple helicates A2 L3 (A=anion) with azobenzene-spaced bis-bis(urea) ligands (L) have proven to undergo a rare in situ photoisomerization (without disassembly of the structure) rather than the typically known, stepwise "disassembly-isomerization-reassembly" process. This is enabled by the structural self-adaptability of the "aniono" assembly arising from multiple relatively weak and flexible hydrogen bonds between the phosphate anion and bis(urea) units. Notably, the Z→E thermal relaxation rate of the isomerized azobenzene unit is significantly decreased (up to 20-fold) for the triple helicates compared to the free ligands. Moreover, the binding of chiral guest cations inside the cavity of the Z-isomerized triple helicate can induce optically pure diastereomers, thus demonstrating a new strategy for making light-activated chiroptical materials.

Abstract
Objective: To evaluate different methods' efficacy of controlling acute bleeding and managing long-term menstruation in patients with heavy menstrual bleeding (HMB) associated with antithrombotic therapy. Methods: The clinical data of 22 cases with HMB associated with antithrombotic therapy admitted to Peking University People's Hospital from January 2010 to August 2022 were analyzed, aged 39 years old (26-46 years). Changes in menstrual volume, hemoglobin (Hb), and quality of life were collected after control of acute bleeding and long-term menstrual management. Menstrual volume was assessed by pictorial blood assessment chart (PBAC), and quality of life was assessed by menorrhagia multi-attribute scale (MMAS). Results: (1) Treatment of acute bleeding: of the 22 cases with HMB associated with antithrombotic therapy, 16 cases were treated in our hospital and 6 in other hospital for emergency bleeding; of the 16 cases treated in our hospital, 3 underwent emergency intrauterine Foley catheter balloon compression due to severe bleeding (Hb decreased by 20 to 40 g/L within 12 hours). Of the 22 cases with antithrombotic therapy-related HMB, 15 (including 2 cases with severe bleeding) underwent emergency aspiration or endometrial resection, and intraoperative placement of levonorgestrel-releasing intrauterine system (LNG-IUS) followed by a significant reduction in bleeding volume; 3 cases had controlled acute bleeding after rivaroxaban dose reduction and continued observation; 2 cases were given gonadotropin-releasing hormone agonists to control acute bleeding in other hospital, of which 1 case was temporarily treated with periodic blood transfusion, and the other one patient underwent total hysterectomy; and 2 cases had temporary amenorrhea with oral mifepristone after intrauterine balloon compression or oral norethindrone. (2) Long-term menstrual management: of the 22 cases with antithrombotic therapy-related HMB, 15 had LNG-IUS placement and 12 had LNG-IUS placement for 6 months, and menstrual volume was significantly reduced [PBAC scores were 365.0 (272.5-460.0) vs 25.0 (12.5-37.5), respectively; Z=4.593, P<0.001], Hb was significantly increased [91.5 g/L (71.8-108.2 g/L) vs 128.5 g/L (121.2-142.5 g/L); Z=4.695, P<0.001], and quality of life was significantly improved [MMAS scores were 415.0 (327.5-472.5) vs 580.0 (570.0-580.0), respectively; Z=-3.062, P=0.002] before placement compared with 6 months after placement. Three rivaroxaban dose reduction patients' PBAC scores decreased by 20 to 35 but remained >100, and perceived quality of life did not change significantly. Two cases with temporary amenorrhea treated with oral mifepristone felt significantly improved quality of life, and the MMAS scores increased by 220 and 180, respectively. Conclusion: Intrauterine Foley catheter balloon compression, aspiration or endometrial ablation could be used to control acute bleeding in patients with antithrombotic therapy-related HMB, and LNG-IUS for long-term management could reduce menstrual volume, increase hemoglobin, and improve the quality of life of patients.

Abstract
BACKGROUND Salivary gland cancer is a rare disease in which cancer cells form in the tissues of the salivary glands. It mostly occurs in the glands that have secretion functions, such as the parotid gland, sublingual gland and submandibular gland. This is very rare when it occurs in other nonsecreting glands. Here, we report one case of salivary gland carcinoma occurring in the thymus and discuss related diagnoses and treatment progress.
CASE SUMMARY One 33-year-old middle-aged man presented with a thymus mass without any clinical symptoms when he underwent regular physical examination. Later, the patient was admitted to the hospital for further examination. Computed tomography (CT) showed that there was a mass of 3 cm × 2.8 cm × 1.5 cm in the thymus area. The patient had no symptom of discomfort or tumor- related medical history before. After completing the preoperative examinations, it was confirmed that the patient had indications for surgery. The surgeon performed a transthoracoscope "thymectomy + pleural mucostomy" for him. During the operation, the tumor tissue was quickly frozen, and the symptomatic section showed a malignant tumor. The final pathological result suggested thymus salivary gland carcinoma- mucoepidermoid carcinoma (MEC). In the second month after surgery, we performed local area radiotherapy for the patient, with a total radiation dose of 50.4 Gy/28Fx. After 12 mo of surgery, the patient underwent positron emission tomography-CT examination, which indicated that there was no sign of tumor recurrence or metastasis. After 16 mo of operation, CT scan re-examination showed that there was no sign of tumor recurrence or metastasis. As of the time of publication, the patient was followed up for one and a half years. He had no sign of tumor recurrence and continued to survive.
CONCLUSION The incidence of MEC in the thymus is low, and its diagnosis needs to be combined with clinical features and imaging methods. Histopathological analysis plays a key role in the diagnosis of the disease. Patients with early-stage disease have a good prognosis and long survival period. In contrast, patients with advanced-stage disease have a poor prognosis and short survival period. Combining radiotherapy and chemotherapy in inoperable patients may prolong survival.

Abstract
Objective: To investigate the correlation between the change of posterior tibial slope (PTS) after unicompartmental knee arthroplasty (UKA) and the contact force at the end stage of knee flexion and extension, as well as the postoperative range of motion. Methods: The data of 38 cases (46 knees) of UKAs undertaken in China-Japan Friendship Hospital from June 2020 to June 2021 were analyzed in this study. A custom-designed force sensor was used to measure gap contact force in the medial gap of UKA. The correlations between each two of the three factors-the change of PTS (∆PTS), the gap contact force of full extension and deep flexion and the range of knee motion were analyzed. Results: Totally of 38 patients (46 knees) were enrolled, including 14 males and 24 females, aged (69.1±7.4) years, with an average follow-up of (11.2±3.7) months. The average gap contact force was (88.3±40.6)N, the adjusted contact force of the full extension gap was 81.7%±33.8%, while that of the deep flexion gap was 55.6%±31.0%. At the last follow-up, the fixed flexion degree[M(Q1, Q3)] was 0°(0°, 3°), which was significantly lower than the preoperative value of 0°(0°, 5°) (P<0.05); the postoperative max flexion degree was 115.9°±16.4°, it was increased when compared with the preoperative value of 112.0°±16.8° (P<0.05); and the postoperative PTS was 8.3°±2.7°, and there was no significant difference with the preoperative value (8.6°±2.1°,P>0.05). There was a positive correlation between ∆PTS and both the contact force of full extension gap and the fixed flexion degree (r=0.334 and 0.317, P<0.05). Besides, there was a negative correlation between ∆PTS and the contact force of the deep flexion gap (r=-0.397, P<0.05). However, the correlations between these two factors and the max flexion degree were not significant (P>0.05). Conclusions: The reduction of PTS in UKA would reduce the contact force of the full extension gap, as well as the postoperative fixed flexion deformity. Besides, it could increase the contact force of the deep flexion gap, but would not influence the max flexion degree of the knee postoperatively.

Abstract
OBJECTIVE To investigate long non-coding RNA (lncRNA)-microRNA (miRNA)-messenger RNA (mRNA) interactions and identify the critical gene regulatory network during Schistosoma japonicum infections and praziquantel treatment using whole transcriptome sequencing. METHODS A total of 110 male C57BL/6 mice were randomly divided into the control group, the infection group and the treatment group. Mice in the infection treatment and the control group were infected with S. japonicum cercariae via the abdomen, and liver specimens were sampled from 10 mice 3, 6, 8 weeks post-infection. Praziquantel treatment was given to mice in the treatment group 8 weeks post-infection, and liver specimens were sampled from 10 mice 2, 4, 6, 8, 10 weeks post-treatment. Total RNA was isolated from mouse liver specimens, and the transcriptome library was constructed for highthroughput whole transcriptome sequencing. The significant differentially expressed genes were subjected to functional annotations, Gene Ontology (GO) terms enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Correlation analysis of liver specimens was performed using R Corrplot and Himsc functions, and the lncRNAmiRNA-mRNA interaction network analysis was performed using R MixOmics and Himsc functions. RESULTS There were 1 176 differentially expressed miRNAs, 5 270 differentially expressed mRNAs, and 2 682 differentially expressed lncRNAs between the infection group and the control group, 1 289 differentially expressed miRNAs, 7 differentially expressed mRNAs, and 69 differentially expressed lncRNAs between the treatment group and the infection group, and 1 210 differentially expressed miRNAs, 4 456 differentially expressed mRNAs, and 2 016 differentially expressed lncRNAs between the treatment group and the control group. Correlation analysis showed a higher correlation of gene expression between the treatment group and the control group. Principal component analysis showed obvious separate clustering between the infection group and the treatment group. The differentially expressed genes with significant relevance were significantly enriched in 24 GO terms, including arachidonic acid metabolic process, xenobiotic catabolic process, unsaturated fatty acid metabolic process, xenobiotic metabolic process, long-chain fatty acid metabolic process, and 8 KEGG metabolic pathways, including cholesterol metabolism, tyrosine metabolism, linoleic acid metabolism, retinol metabolism, and steroid hormone biometabolism. CONCLUSIONS There were 23 mRNAs including Cyp2b9 and 14 lncRNAs including Rmrpr in the core position of the gene regulatory network, which may play a critical role in S. japonicum infections and praziquantel treatment, and 9 miRNAs including miR-8105 may serve as potential molecular markers for diagnosis of S. japonicum infections.

Abstract
The sterile inflammation (SI) of the urinary tract is a common problem requiring serious consideration after prostatectomy. This study mainly focuses on the role of the reactive oxygen species-NLR family, pyrin domain-containing 3 (ROS-NLRP3) signaling pathway in SI after thulium laser resection of the prostate (TmLRP). Urinary cytokines were determined in patients who received TmLRP, and heat shock protein 70 (HSP70) was detected in the resected tissues. The involvement of ROS signaling in HSP70-induced inflammation was explored in THP-1 cells with or without N-acetyl- l-cysteine (NAC) pretreatment. The function of NLRP3 and Caspase-1 was determined by Western blot analysis, enzyme-linked immunosorbent assay (ELISA), and polymerase chain reaction. These phenomena and mechanisms were verified by the beagle models that received TmLRP. Clinical urine samples after TmLRP showed high expression of inflammatory factors and peaked 3-5 days after surgery. The high expression of HSP70 in the resected tissues was observed. After HSP70 stimulation, the expression of ROS, NLRP3, Caspase-1, and interleukin-18 (IL-18) increased significantly and could be reduced by ROS inhibitor NAC. The expression of IL-1β and IL-18 could be inhibited by NLRP3 or Caspase-1 inhibitors. In beagle models that received TmLRP, HSP70, NLRP3, Caspase-1, IL-1β, and IL-18 were highly expressed in the wound tissue or urine, and could also be reduced by NAC pretreatment. Activation of the ROS-NLRP3 signaling pathway induces SI in the wound after prostatectomy. Inhibition of this pathway may be effective for clinical prevention and treatment of SI and related complications after prostatectomy.

Abstract
Background Psoriasis is a common chronic inflammatory disease caused by excessive activation of CD4+T cells, including Th17, Th1 and Th22. The role of CD8+T cells in psoriasis pathogenesis remains poorly understood. Aim To identify the phenotype of CD8+T cells in patients with psoriasis and to investigate its role in the formation of lesions. Methods The phenotype of CD8+T cells in psoriatic lesions was detected by immunofluorescence staining. Flow cytometry was performed to detect their phenotype in peripheral blood. Thereafter, coculture of CD8αα+T cells with autogenous CD4+T cells was performed to investigate the function of CD8αα+T cells in patients with psoriasis. Finally, pro‐inflammatory factors produced by CD8αα+T cells were examined by immunofluorescence staining and flow cytometry. Results Compared to the CD8αβ+T cells, CD8αα+T cell infiltration in psoriatic lesions markedly increased. Moreover, epidermal CD8αα+T cells exhibited tissue‐resident memory T cells (TRM) phenotypes and dermal CD8αα+T cells exhibited effector memory (TEM) phenotypes in psoriatic lesions. Additionally, we found that CD8αα+T cells from patients with psoriasis did not express the markers of regulatory T cells and could promote the proliferation of CD4+T effector cells and produce interleukin‐17 and interferon‐γ. Conclusions Our findings demonstrate that CD8αα+T cells contribute to the pathogenesis of psoriasis by producing pro‐inflammatory factors.

Abstract
Objective: To investigate the safety of definitive surgery for chronic radiation intestinal injury. Methods: A descriptive case series study was performed. Clinical data of 105 patients who were diagnosed as chronic radiation intestinal injury, had complete data and received definitive surgery (the radiation-induced intestinal segment and digestive tract reconstruction) at Department of Gastrointestinal Surgery of Beijing Tsinghua Changgung Hospital from June 2016 to May 2020 were retrospectively analyzed. There were 30 males (28.6%) and 75 females (71.4%) with the median age of 58 years (P25, P75: 52, 64 years). Patients who had tumor recurrence or refused surgical treatment were excluded. According to the preoperative evaluation and clinical manifestations, to select the resection range. Outcome parameters: (1) preoperative evaluation (nutrition risk assessment and status of obstruction or fistula); (2) clinical manifestations and treatment strategies; (3) details of surgical parameters; (4) postoperative complications, and Clavien-Dindo classification III to V was defined as main moderate-severe complication. Results: (1) Preoperative evaluation: Eighty-eight patients (83.8%) developed symptoms of chronic radiation intestinal injury more than 1 year after the end of radiotherapy. Ninety-eight patients (93.3%) had preoperative NRS-2002 score ≥3, 74 patients (70.5%) received preoperative parenteral nutritional support, and the median time of nutritional support was 10.5 (7.0, 16.0) days. Sixteen patients (15.2%) received small intestinal decompression tube implantation due to severe obstruction. (2) Clinical manifestations and treatment strategies: Among 105 patients, 87 (82.9%) presented with obstruction and received definitive resection of the radiation-induced intestinal segment plus one-stage digestive tract reconstruction; 18 (17.1%) presented with intestinal fistula and all of them received definitive resection of the radiation-induced intestinal segment, intestinal fistula plus one-stage digestive tract reconstruction. Among above 18 patients with fistula, 3 patients with ileorectal stump fistula received pedicled pelvic closure of greater omentum at the same time; 4 patients had ileal vesical fistula, of whom 2 patients received cystectomy and bladder repair due to preoperative nephrostomy decompression, and the other 2 patients received transection of the small intestine proximal and distal to the fistula and anastomosis of the intestinal loop without fistula resection, intestinal fistula or bladder fistula repair. (3) The details of surgical parameters: Median operative time and intraoperative blood loss was 230 (180, 300) minutes and 50 (20, 50) ml respectively. Ninety-two patients (92/105, 87.6%) underwent ileocolonic anastomosis, and anastomosis on the hepatic flexure or splenic flexure colon were performed in 88 (83.8%) and 4 (3.8%) patients respectively. Ileoileal anastomosis was performed in 13 patients (12.4%). The anastomotic site of 92 patients (87.6%) was strictly located in the contralateral quadrant of the radiation field, and the anastomotic site of 13 patients (12.4%) was far from the radiation field. Nine patients (8.6%) had more than one anastomosis, 5 patients (4.8%) had less than 180 cm of residual small intestine, 7 patients (6.7%) underwent retrograde intestinal permutation, 4 patients (3.8%) underwent abdominal wall reconstruction surgery due to abdominal wall defects, and 87 patients (82.9%) had severe abdominal pelvic adhesions (grade 3-4 adhesions). Intraoperative complications occurred in 3 patients (2.9%), which were found in time and handled properly. The median postoperative hospital stay was 13.0 (12.0, 24.5) days, and all the patients had resumed oral feeding upon discharge. (4) Postoperative complications: Fourteen patients (13.3%) had 18 major complications (grade III to V). The incidence of postoperative anastomotic leakage was 5.7% (6/105), and the incidence of anastomotic leakage for ileocolon anastomosis and ileoileal anastomosis was 2.2% (2/92) and 4/13, respectively (χ(2)=17.29, P<0.001). The incidence of postoperative anastomotic leakage of intestinal fistula and intestinal obstruction was 3/18 and 3.4% (3/87), respectively (χ(2)=4.84, P=0.028). The mortality at 30 days after operation was 1.0% (1/105), after abdominal infection and septic shock caused by postoperative anastomotic leakage resulting in multiple organ failure. Conclusion: For chronic radiation intestinal injury patients with obstruction or fistula, definitive surgical treatment is feasible and safe with acceptable major complications.

Abstract
Multi-functional materials have received wide attention due to their potential applications in various fields; therefore, developing a simple and easy strategy for the preparation of multi-functional materials is an interesting issue. In this work, a novel supramolecular gel, TP-QG, has been successfully constructed via the assembly of a simple methoxyl-pillar[5]arene host (TP) and a tripodal (tri-pyridine-4-yl)-amido-benzene guest (Q). Interestingly, TP-QG could act as a multi-functional material and showed strong fluorescence, good self-healing, host-guest stimuli-responsiveness and conductive properties. Due to these properties, TP-QG shows a fascinating application prospect. For instance, TP-QG could exhibit ultrasensitive fluorescence response for Fe3+ and F- in water via the fluorescence "ON-OFF-ON" pathway; the lowest detection limit (LOD) of TP-QG for Fe3+ was 2.32 × 10-10 M and the LOD of TP-QG-Fe for F- was 4.30 × 10-8 M. These properties permit TP-QG to act as not only a Fe3+ and F- sensor, but also an "ON-OFF-ON" fluorescence display material and an efficient logic gate. Meanwhile, the xerogel of TP-QG could remove Fe3+ from water, and the adsorption ratio was 98.68%; the xerogel of TP-QG-Fe could also remove F- from water; the removal ratio was about 87.92%. This work provides a feasible way to construct multi-functional smart materials by host-guest assembly.

Abstract
Objective: To observe the efficacy and safety of Kangbingdu granules (KBD) in the treatment of influenza. Methods: A multicenter, randomized, double-blind, double-dummy, and positive-drug parallel control trial was conducted in 27 Grade ⅢA hospitals in China and the subjects were randomly assigned to the KBD test group or the oseltamivir phosphate capsule control group at a ratio of 1∶1. 200 subjects were planned to be enrolled in each group. The experimental group was given KBD (18g each time, 3 times a day) and oseltamivir phosphate simulator orally, while the control group was given oseltamivir phosphate capsule (75 mg each time, twice a day) and KBD simulator orally for 5 days. The primary efficacy indicators included the remission time of major clinical symptoms and the time of complete defervescence. The secondary efficacy indicators included dosage of acetaminophen, the change of traditional Chinese medicine (TCM) syndrome score and the remission time of other important clinical symptoms. The efficacy of KBD in the test group and Oseltamivir phosphate control group were compared. Adverse events or adverse reactions were observed at the same time to evaluate the safety of KBD Granules. Results: A total of 393 subjects from 27 Grade ⅢA hospitals in China were enrolled. The experimental group included 195 subjects and 191 subjects (97.95%) completed the trial, While the control group included 198 subjects and 195 subjects (98.48%) completed the trial. There was no significant difference in the shedding rate and rejection rate between the two groups (P>0.05). In the Full Analysis Set (FAS), the mean age of the experimental group was (34.9±14.4) years old, with 83 males (42.78%). The mean age of the control group was (33.3±13.5) years old, with 78 males (39.59%). There were no statistically significant differences between the two groups in demographic data, physical examination, viral pathogen detection, total score of TCM syndromes and scores of each symptom at baseline (P>0.05). In the FAS, the remission time M (Q1, Q3) of major clinical symptoms was 3.0 (3.0, 4.0) days in the experimental group and 3.0 (3.0, 4.0) days in the control group, and the difference was not statistically significant (P>0.05). The time M (Q1, Q3) of complete defervescence was 34.0 (20.3, 49.0) hours in the experimental group and 36.5 (19.6, 48.8) hours in the control group, and the difference was not statistically significant (P>0.05). KBD granules had the same effect as Oseltamivir phosphate capsule (P>0.05) in terms of acetaminophen dosage, TCM syndrome effect and disappearance rate of most important clinical symptoms. Meanwhile, the disappearance rate of dizziness and chest distress on day 3 in the KBD granules group was better than that of oseltamivir phosphate capsule (P<0.05). Conclusion: KBD granules have the same efficacy as Oseltamivir Phosphate capsule in the treatment of influenza and the drug safety is good.

Abstract
Neurotrauma has been recognized as a risk factor for neurodegenerative diseases, and sex difference of the incidence and outcome of neurodegenerative diseases has long been recognized. Past studies suggest that microglia could play a versatile role in both health and disease. So far, the microglial mechanisms underlying neurodegeneration and potentially lead to sex-specific therapies are still very open. Here we applied whole transcriptome analysis of microglia acutely isolated at different timepoints after a cortical stab wound injury to gain insight into genes that might be dysregulated and transcriptionally different between males and females after cortical injury. We found that microglia displayed distinct temporal and sexual molecular signatures of transcriptome after cortical injury. Hypotheses and gene candidates that we presented in the present study could be worthy to be examined to explore the roles of microglia in neurotrauma and in sex-biased neurodegenerative diseases.

Abstract
Objective: To investigate the clinical characteristics and related factors of acute tubular necrosis (ATN) in patients with minimal change disease (MCD). Methods: Patients from Chinese PLA General Hospital who were pathologically diagnosed with MCD and had clinical manifestations of nephrotic syndrome from January 1, 2013 to December 31, 2019 were included. The clinical and pathological data of patients were retrospectively analyzed. Meanwhile, the incidence and clinical characteristics of ATN in different age groups were compared. The risk factors for ATN were assessed using binary logistic regression. Results: A total of 525 patients were included, with a gender ratio of 1.56∶1 (male: female), aged 33 (21, 48) years old. ATN occurred in 49 (9.3%) of 525 patients, of which 34 were male and 15 were female. The incidence of ATN increased with age in MCD patients of different age groups (χ(2)=31.442, P<0.001). The incidence of ATN in groups of age≤20 years, 21-40 years, 41-60 years, and >60 years was 2.4% (3/123), 5.2% (10/192), 13.2% (20/152) and 27.6% (16/58), respectively. Elevations of alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT) and serum IgE occurred in 92 patients (17.5%), 53 patients (10.1%), 99 patients (18.9%), and 303 patients (57.7%), respectively. There were significant differences in age, ALT, serum creatinine, serum urea nitrogen, history of diabetes and history of hypertension between non-ATN group and ATN group (all P<0.05). The results of logistic regression analysis showed that>40 years old (OR=6.283, 95% CI: 2.695-14.649, P<0.001) and serum albumin (OR=0.924, 95% CI: 0.857-0.997, P=0.040) was independently associated with ATN in MCD patients. Conclusion: Age>40 years is an independent risk factor and serum albumin is a protective factor for ATN in MCD patients.

Abstract
Primordial follicle assembly in the mouse occurs during perinatal ages and largely determines the ovarian reserve that will be available to support the reproductive life span. The development of primordial follicles is controlled by a complex network of interactions between oocytes and ovarian somatic cells that remain poorly understood. In the present research, using single-cell RNA sequencing performed over a time series on murine ovaries, coupled with several bioinformatics analyses, the complete dynamic genetic programs of germ and granulosa cells from E16.5 to postnatal day (PD) 3 were reported. Along with confirming the previously reported expression of genes by germ cells and granulosa cells, our analyses identified 5 distinct cell clusters associated with germ cells and 6 with granulosa cells. Consequently, several new genes expressed at significant levels at each investigated stage were assigned. By building single-cell pseudotemporal trajectories, 3 states and 1 branch point of fate transition for the germ cells were revealed, as well as for the granulosa cells. Moreover, Gene Ontology (GO) term enrichment enabled identification of the biological process most represented in germ cells and granulosa cells or common to both cell types at each specific stage, and the interactions of germ cells and granulosa cells basing on known and novel pathway were presented. Finally, by using single-cell regulatory network inference and clustering (SCENIC) algorithm, we were able to establish a network of regulons that can be postulated as likely candidates for sustaining germ cell-specific transcription programs throughout the period of investigation. Above all, this study provides the whole transcriptome landscape of ovarian cells and unearths new insights during primordial follicle assembly in mice.

Abstract
The booming of host-guest assembly-based supramolecular chemistry provides abundant ways to construct functional systems and materials. Attracted by the important application prospect of white light emission and aggregation-induced emission (AIE) materials, herein, we report an efficient way for fabricating metal-free white light-emitting AIE materials through the supramolecular assembly of simple organic compounds: methoxyl pillar[5]arene (MP5) and tri-(pyridine-4-ylamido)benzene (TAP). By host-guest assembly, MP5 and TAP formed a supramolecular polymer (MP5-T); meanwhile, the MP5-T xerogel powder emitted white light at CIE coordinates (0.29 and 0.29). The supramolecular assembly and white light-emitting mechanisms were carefully investigated by experiments as well as quantum chemical calculations including density functional theory (DFT), reduced density gradient, electrostatic surface potential, independent gradient model, and frontier molecular orbital (highest-occupied molecular orbital-lowest-unoccupied molecular orbital) analyses. Interestingly, according to the experiments and calculations, the supramolecular assembly is critical in the white light-emitting phenomenon. Moreover, in this work, the quantum chemical calculations could not only support experimental phenomena but also provide deep understanding and visualized presentation of the assembly and emission mechanism. In addition, the obtained MP5-T solid powder could serve as a novel and easy means to make material for white light-emitting devices.

Abstract
Asbestos is classified as a Class 1 carcinogen by the International Cancer Organization (IARC) , and almost all types of asbestos are carcinogenic. The clinical data of 30 asbestos-induced occupational tumor patients in Qingdao city from January 2002 to May 2019 were analyzed, including 24 cases of asbestos-induced lung cancer and 6 cases of asbestos-induced malignant mesothelioma. Mesothelioma was significantly worse than lung cancer in terms of malignancy, the survival time of patients is shorter, and the mortality rate was higher. Both its diagnostic methods and treatment methods should be improved. The high incidence of asbestos-caused tumors is coming. It is recommended that workers exposed to asbestos dust should undergo regular chest CT examinations for early detection, early diagnosis and early treatment.

Abstract
Paraquat, one of non-selective herbicides, is widely used in agricultural production. However, it can cause death of people or animals quickly owing to its fatal toxicity. In the present work, for efficient separation and removal of the paraquat, a concept "employ collaboration effect to enhance the Host-Guest interactions" was rationally introduced into the design of paraquat adsorbent material. According to this concept, a novel linear tri-pillar[5]arene-based acceptor molecule was synthesized. Interestingly, the acceptor shows outstanding adsorption properties for paraquat through the collaboration effect of the adjacent pillar[5]arene moieties in the linear tri-pillar[5]arene acceptor. Compared with other adsorbents such as activated carbon and single-pillar[5]arene-based adsorbent materials, the linear tri-pillar[5]arene acceptor shows higher adsorption rate for paraquat. Additionally, the linear tri-pillar[5]arene acceptor was applied to adsorb the commercial pesticide paraquat sample in water with adsorption rate of 98%. Therefore, the linear tri-pillar[5]arene acceptor could serve as a paraquat adsorbent material and convey greatly potential application in the field of removal of paraquat. The concept "employ collaboration effect to enhance the Host-Guest interactions" is a useful way for the development of adsorption materials.

Abstract
Stimuli-responsive optical materials attract lots of attention due to their broad applications. Herein, a novel smart stimuli-responsive supramolecular polymer was successfully constructed using a simple tripodal quaternary ammonium-based gelator (TH). The TH self-assembles into a supramolecular polymer hydrogel (TH-G) and shows aggregation-induced emission (AIE) properties. Interestingly, the transparency and fluorescence of the TH-G xerogel film (TH-GF) could be reversibly regulated by use of triethylamine (TEA) and hydrochloric acid (HCl) vapor. When alternately fumed with TEA and HCl vapor, the optical transmittance of the TH-GF was changed from 8.9% to 92.7%. Meanwhile, the fluorescence of the TH-G shows an "ON/OFF" switch. The reversible switching of the transparency and the fluorescence of the TH-GF is attributed to the assembly and disassembly of the supramolecular polymer TH-G. Based on these stimuli-response properties, the TH-GF could act as an optical material and shows potential applications as smart windows or fluorescent display material controlled by TEA and HCl vapor.

Abstract
Neuropsychiatric disorders are the leading cause of mental and intellectual disabilities worldwide. Current therapies against neuropsychiatric disorders are very limited, and very little is known about the onset and development of these diseases, and their most effective treatments. MIR137 has been previously identified as a risk gene for the etiology of schizophrenia, bipolar disorder, and autism spectrum disorder. Here we generated a forebrain-specific MIR137 knockout mouse model, and provided evidence that loss of miR-137 resulted in impaired homeostasis of potassium in mouse hippocampal neurons. KCC2, a potassium-chloride co-transporter, was a direct downstream target of miR-137. The KCC2 specific antagonist VU0240551 could balance the current of potassium in miR-137 knockout neurons, and knockdown of KCC2 could ameliorate anxiety-like behavior in MIR137 cKO mice. These data suggest that KCC2 antagonists or knockdown might be beneficial to neuropsychiatric disorders due to the deficiency of miR-137.

Abstract
Cancer-associated fibroblasts (CAFs) are an important component of the tumor microenvironment and contribute to tumor cell proliferation and metastasis. Microfibrillar-associated protein 5 (MFAP5), a component of elastic microfibers and an oncogenic protein in several types of tumors, is secreted by CAFs. However, the role of MFAP5 in the bladder cancer remains unclear. Here, we report that MFAP5 is upregulated in bladder cancer and is associated with poor patient survival. Downregulation of MFAP5 in CAFs led to an impairment in proliferation and invasion of bladder cancer cells. Luciferase reporter assays and electrophoretic mobility shift assays (EMSA) showed QKI directly downregulates MFAP5 in CAFs. In addition, CAFs-derived MFAP5 led to an activation of the NOTCH2/HEY1 signaling pathway through direct interaction with the NOTCH2 receptor, thereby stimulating the N2ICD release. RNA-sequencing revealed that MFAP5-mediated PI3K-AKT signaling activated the DLL4/NOTCH2 pathway axis in bladder cancer. Moreover, downregulation of NOTCH2 by short hairpin RNA or the inactivating anti-body NRR2Mab was able to reverse the adverse effects of MFAP5 stimulation in vitro and in vivo. Together, these results demonstrate CAFs-derived MFAP5 promotes the bladder cancer proliferation and metastasis and provides new insight for targeting CAFs as novel diagnostic and therapeutic strategy.

Abstract
Structural alterations in fibroelastic components of the penile corpus cavernousum (CC) may impair its compliance, resulting in venous leakage and erectile dysfunction (ED). Our study evaluated the effectiveness of noninvasive two-dimensional shear-wave elastography (2-D SWE) in quantifying penile CC lesions in rabbits with hyperlipidemia-induced ED. A total of 12 New Zealand white rabbits were randomly divided into two groups. Six were fed a high-cholesterol diet containing 2% cholesterol and 8.5% lard for 10 weeks and the other six were fed normal diet as controls. We measured the shear-wave elastic quantitative (SWQ) value of penile CC by 2-D SWE. Erectile function was investigated by intracavernous injection of papaverine, and immunohistochemical (IHC) staining and the western blot analysis to determine the penile CC lesions. After 10 weeks, the SWQ values obtained from penile CC were remarkably higher in the high-cholesterol-fed compared with the control group, and the ΔICP (ICP plateau minus ICP baseline)/MAP (ICP: intracavernous pressure, MAP: mean arterial pressure) was markedly decreased. The IHC staining and western blot revealed extracellular matrix (ECM) accumulation in penile cavernous tissues, and the smooth muscle cell (SMC) phenotypic transition was affected, as indicated by reduced alpha-smooth muscle actin and calponin-1 expression and increased phospho-myosin light chain20 (p-MLC20)/MLC20 and osteopontin expression. Hyperlipidemia resulted in ECM accumulation accompanied with SMC phenotypic transition in penile CC and impaired the erectile function eventually. These might, in turn, lead to variations in the SWQ values. It suggests that 2-D SWE may be a novel, noninvasive and effective approach that distinguishes penile CC lesions secondary to hyperlipidemia from normal.

Abstract
A bi-component supramolecular gel (RQ) was successfully constructed by the assembly of the gelators 4-aminophenyl functionalized naphthalimide derivative (R) and tri-(pyridine-4-yl)-functionalized trimesic amide (Q) in DMSO-H2O (6.1 : 3.9, v/v) binary solution. The gel RQ exhibits excellent self-healing capacity. Interestingly, the RQ could fluorescently detect and reversibly remove Hg2+ from water through cation-π interactions with high selectivity, efficient adsorption and quick response. The limit of lowest detection (LOD) of the RQ for Hg2+ is 4.52 × 10-8 M and the separation ratio is 91.14%. Moreover, the RQ could be efficiently recycled and regenerated with little loss via a simple treatment by I-. Notably, thin films based on RQ and RQ + Hg2+ were prepared, which could serve as convenient and efficient test tools for the detection of Hg2+ and I-, respectively. This work provided an efficient method and novel supramolecular gel material for the separation and detection of Hg2+.

Abstract
Anxiety and depression are major public health concerns worldwide. Although genome-wide association studies have identified several genes robustly associated with susceptibility for these disorders, the molecular and cellular mechanisms associated with anxiety and depression is largely unknown. Reduction of microRNA-137 (miR-137) level has been implicated in the etiology of major depressive disorder. However, little is known about the in vivo impact of the loss of miR-137 on the biology of anxiety and depression. Here, we generated a forebrain-specific miR-137 knockout mouse line, and showed that miR-137 is critical for dendritic and synaptic growth in the forebrain. Mice with miR-137 loss-of-function exhibit anxiety-like behavior, and impaired spatial learning and memory. We then observe an elevated expression of EZH2 in the forebrain of miR-137 knockout mice, and provide direct evidence that knockdown of EZH2 can rescue anxious phenotypes associated with the loss of miR-137. Together our results suggest that loss of miR-137 contributes to the etiology of anxiety, and EZH2 might be a potential therapeutic target for anxiety and depressive phenotypes associated with the dysfunction of miR-137.

Abstract
Objective: To investigate the incidence of asymptomatic sinusitis in children by magnetic resonance imaging. Method: Collected the head MRI of 1-12 years old children. According to the examination site,the MRI group and the pituitary MRI group (both sinus level) were included.The nasal-sinusitis-like changes in the field were used as positive criteria. Statistical analysis was conducted on the test results. Result: In 3 900 children with MRI, the positive rate of sinusitis was 30.21%. The positive rate increased from 2 years old to 3 years old and remained at the age of 11 years.The higher positive rate was slightly decreased at 12 years old; 1 228 cases of pituitary MRI examination, the positive rate of nasal-sinusitis was 38.27%, the positive rate increased significantly from the age of 2, reached the peak at 6 years old, and then fell back, still kept high positive rate, the lowest to 12 years old. The positive rate of total sinusitis was 32.14%. No obvious difference was found between two groups. Conclusion: Children's skull and pituitary MRI imaging suggests that the positive rate of nasal-innocuous sinusitis is related to age, peaking at 3 to 8 years old, and then gradually decreasing.

Abstract
Objective: To explore the associations between maternal and prenatal depressive symptoms and children's behavioral problems at 2 years old. Methods: In the present study, a total of 491 mother-child pairs were selected from the Shanghai-Minhang Birth Cohort Study (S-MBCS) which was conducted in Maternal and Child Health Hospital of Minhang District in Shanghai between April and December, 2012. Data from the Center for Epidemiologic Studies on Depression was gathered to assess the maternal depressive symptoms in the second and third trimester of pregnancy, as well as at 6 months and 12 months postpartum. Neurodevelopment at 2 years was assessed, using the Child Behavior Checklist. We used generalized linear models with a log-link function and a Binomial distribution to estimate the risk ratios (RRs) and 95%CIs, on children's behavioral problems at 2 years of age. Sensitivity analyses were performed among participants without postpartum depressive symptoms. Results: After adjustment on factors as maternal age, gestation week, average monthly income per person, parental education and children's gender etc., maternal depression in second trimester of pregnancy was found associated with higher risk of both developing emotional (RR=2.61, 95%CI: 1.36-4.99) and internalizing problems (RR=1.94, 95%CI: 1.22-3.08). However, maternal depression in third trimester was found to be associated with higher risks of developing emotional (RR=6.46, 95%CI: 3.09-13.53), withdrawn (RR=2.42, 95%CI: 1.16-5.02), aggressive (RR=2.93, 95%CI: 1.45-5.94), internalizing (RR=1.79, 95%CI: 1.01-3.16) or externalizing problems (RR=2.56, 95%CI:1.49-4.42). In sensitivity analysis, antenatal maternal depression was found positively associated with children's emotional, internalizing and externalizing problems and the differences all statistically significant. Conclusions: Maternal depression during pregnancy might increase the risks of children's behavioral problems. In order to decrease the incidence of children's behavioral problems and promoting both maternal and child health status, monitoring program regarding maternal mental health care should be strengthened.

Abstract
BACKGROUND Increased prostatic smooth muscle tone and hyperplastic growth contribute to urethral obstruction and voiding symptoms in benign prostatic hyperplasia (BPH). It has been suggested that different proliferative potential of stromal cells between transition zone (TZ) and adjoining regions of the prostate plays a significant role in the development of BPH. However, the molecular mechanisms of this hyperplastic process remain unclear. We found tumor necrosis factor receptor-associated factor 6 (TRAF6) highly expressed in TZ stromal cells compared to peripheral zone (PZ) stromal cells by gene array analyzes. Therefore, we aim to study the potential mechanisms of stromal TRAF6 in promoting BPH progression. METHODS Stromal cells obtained from BPH-derived primary cultures. The TRAF6-siRNA vector were constructed and transfected into cultured human BPH primary TZ stromal cells, and TRAF6-overexpressing vector were constructed and transfected into cultured human BPH primary PZ stromal cells. Stromal cells were recombined with BPH-1 cells then subcutaneously inoculated into the kidney capsule of male nude mice. Cell proliferation was evaluated by CCK-8 assay. Multiple proteins in the Akt/mTOR pathway were assessed using western blot. RESULTS TRAF6 levels were increased in TZ stroma compared with PZ stroma of BPH. The in vitro cell culture and in vivo cell recombination revealed that selective downregulation of TRAF6 in TZ stromal cells led to suppression of the proliferation, while upregulation of TRAF6 in PZ stromal cells enhanced the proliferation. We found that the Phosphorylation and Ubiquitination of Akt as well as the Phosphorylation of mTOR, P70S6K were decreased when TRAF6 was downregulated in primary cultured TZ stromal cells of BPH. CONCLUSIONS TRAF6 can promote the proliferation of stromal cells of BPH via Akt/mTOR signaling. Our results may make stromal TRAF6 responsible for zonal characteristic of BPH and as a promising therapeutic strategy for BPH treatment.

Abstract
Objective: This study evaluated the atypical computed tomography (CT) manifestations of thoracic sarcoidosis. Methods: Medical data of 190 patients with thoracic sarcoidosis were retrospectively reviewed. Results: The atypical CT manifestations of thoracic sarcoidosis observed were unilateral hilar lymphadenopathy with or without mediastinal lymphadenopathy(n=12, 6.3%), mediastinal lymphadenopathy without hilar lymphadenopathy(n=9, 4.7%), patchy consolidation (n=23, 12.1%), sarcoid galaxy sign (n=22, 11.6%), reversed halo sign (n=1, 0.5%), and ground-glass opacities (n=52, 27.4%). Air trapping was found in 8 of 10 patients who underwent both inspiratory and expiratory CT. Post-treatment CT scans showed improvements in most patients. Of the 12 patients with unilateral hilar lymphadenopathy with or without mediastinal lymphadenopathy, 10(83.3%) improved. Of the 9 patients with mediastinal lymphadenopathy without hilar lymphadenopathy, 8(88.9%) improved. Of the 23 patients with patchy consolidation, 15(65.2%) improved. Of the 22 patients with the sarcoid galaxy sign, 16(72.7%) improved. The patient with the reversed halo sign improved completely. Of the 52 patients with ground-glass opacities, 31(59.6%) improved. Of the 8 patients with air trapping, 7(87.5%) improved. Conclusions: The atypical imaging manifestations of thoracic sarcoidosis included unilateral hilar lymphadenopathy with or without mediastinal lymphadenopathy, mediastinal lymphadenopathy without hilar lymphadenopathy, patchy consolidation, the sarcoid galaxy sign, the reversed halo sign, ground-glass opacity, and air trapping. These lesions mostly improved after treatment. Familiarity with these atypical signs will help increase the diagnostic accuracy of imaging studies for thoracic sarcoidosis.

Abstract
OBJECTIVE To observe the effect of Huangjing Zanyu Capsule (HZC) on sperm mitochondrial membrane potential (MMP) in asthenozoospermia patients. METHODS We assigned 70 asthenozoospermia patients to a treatment group (n = 39) and a control group (n = 31), the former treated with oral HZC at the dose of 4 capsules tid for 3 months while the latter left untreated. We obtained semen parameters from the patients and detected their sperm mitochondrial membrane potentials (MMP) by JC-1 staining and flow cytometry before and after medication, followed by comparison between the two groups. RESULTS The total effectiveness rate was 71.05% in the treatment group and natural pregnancy was achieved in 3 cases during the medication. A total of 35 patients in the treatment group and 30 controls completed all the laboratory examinations after a 3-month observation. Compared with the controls, the patients treated with HZC exhibited significant improvement after medication in MMP (variation value: [1.19 ± 10.36]% vs [20.28 ± 14.21]%, P <0.01), total sperm motility (variation value: [3.46 ± 8.67]% vs [20.68 ± 14.12]%, P <0.01), the percentage of progressively motile sperm (variation value: [2.26 ± 8.29]% vs [17.58 ± 12.73]%, P <0.01), and the percentage of morphologically normal sperm (variation value: [0.23 ± 3.48]% vs [3.37 ± 3.99]%, P <0.01). MMP was significantly correlated with total sperm motility (r = 0.69, P <0.01), progressive sperm motility (r = 0.75, P <0.01) and normal sperm morphology (r = 0.26, P <0.01). CONCLUSIONS Huangjing Zanyu Capsule can enhance sperm mitochondrial membrane potential and sperm mitochondrial function, thus improving total sperm motility, progressive sperm motility and normal sperm morphology. It is safe and effective for the treatment of asthenospermia.

Abstract
AIM To investigate the underlying mechanism by which CXCL12 and CXCL6 influences the metastatic potential of colon cancer and internal relation of colon cancer and stromal cells.
METHODS Western blotting was used to detect the expression of CXCL12 and CXCL6 in colon cancer cells and stromal cells. The co-operative effects of CXCL12 and CXCL6 on proliferation and invasion of colon cancer cells and human umbilical vein endothelial cells (HUVECs) were determined by enzyme-linked immunosorbent assay, and proliferation and invasion assays. The angiogenesis of HUVECs through interaction with cancer cells and stromal cells was examined by angiogenesis assay. We eventually investigated activation of PI3K/Akt/mTOR signaling by CXCL12 involved in the metastatic process of colon cancer.
RESULTS CXCL12 was expressed in DLD-1 cancer cells and fibroblasts. The secretion level of CXCL6 by colon cancer cells and HUVECs were significantly promoted by fibroblasts derived from CXCL12. CXCL6 and CXCL2 could significantly enhance HUVEC proliferation and migration (P < 0.01). CXCL6 and CXCL2 enhanced angiogenesis by HUVECs when cultured with fibroblast cells and colon cancer cells (P < 0.01). CXCL12 also enhanced the invasion of colon cancer cells. Stromal cell-derived CXCL12 promoted the secretion level of CXCL6 and co-operatively promoted metastasis of colon carcinoma through activation of the PI3K/Akt/mTOR pathway.
CONCLUSION Fibroblast-derived CXCL12 enhanced the CXCL6 secretion of colon cancer cells, and both CXCL12 and CXCL6 co-operatively regulated the metastasis via the PI3K/Akt/mTOR signaling pathway. Blocking this pathway may be a potential anti-metastatic therapeutic target for patients with colon cancer.

Abstract
BACKGROUND The wound-healing process is very important for reducing complications after thulium laser resection of the prostate (TmLRP). The retinoic acid (RA) signaling pathway has been well studied in the wound-healing process of the skin and other organs. The goals of this study were to identify the role of RA signaling in the repair of the prostate after TmLRP and to investigate the molecular mechanism of this process. RESULTS Retinoic acid receptors (RARs) were present in the prostate, and their expression was increased after TmLRP. RARβ was expressed in the macrophages and may be related to the role of stromal cells in the wound-healing process. In vitro, RA enhanced the function of anti-inflammatory macrophages and promoted stromal cell activation and angiogenesis. Arg1 was also increased via RARβ after treatment with RA. MATERIALS AND METHODS The expression of RARs was analyzed in vivo by immunohistochemistry (IHC), real time qPCR, and western blot analysis. THP-1 cells were co-treated with or without RA and stimulating factor and then assessed by ELISA and qPCR. The supernatants from these cells were cultured with stromal cells and vascular endothelial cells, and the effects on these cells were analyzed. CONCLUSIONS We found that RA signaling was involved in the wound-healing process of the prostate after TmLRP. RA treated macrophages activated stromal cells and promoted angiogenesis. RARβ was the key isoform in this process.

Abstract
Primary omental infarction (POI) is a rare cause of acute abdomen. Most patients have aggravating abdominal pain without gastrointestinal symptoms. Here, we report a case of omental infarction in a 50-year-old woman, who had left abdominal pain and intestinal obstruction. Preoperative computed tomography (CT) of the abdomen showed a left ovarian cyst measuring 6.0 cm × 4.5 cm but otherwise seemed normal initially. The white blood cell count was 9.71 × 109/L, and D-dimer was 1.58 mg/L. Laparoscopic exploration was performed 1 day after admission because of peritonitis and intestinal obstruction. During the exploration, a segment of congested necrotic omentum was found adhering to the abdominal wall with a segment of small intestine. Bloody ascites was also observed in the abdominal cavity. We resected the nonviable segmental omentum, and the ovarian cyst was removed by the gynecologist using laparoscopic procedures. Final pathological findings confirmed POI. While reanalyzing the preoperative CT, a segmental fat mass with an increased density was noted in the left lower quadrant, which was consistent with the intraoperative view 6 days after surgery. The patient recovered uneventfully and was discharged.

Abstract
The 2-μm thulium laser resection of the prostate-tangerine technique (TmLRP-TT) has been introduced as a minimally invasive treatment for benign prostatic hyperplasia (BPH). This study was undertaken to assess the clinical efficacy and safety of TmLRP-TT for the treatment of BPH patients with previously negative transrectal prostate biopsy. A prospective analysis of 51 patients with previously negative transrectal prostate biopsy who underwent surgical treatment using TmLRP-TT was performed from December 2011 to December 2013. Preoperative status, surgical details, and perioperative complications were recorded. The follow-up outcome was evaluated with subjective and objective tests at 1 and 6 months. TmLRP-TT was successfully completed in all patients. Mean prostate volume, operative duration, and catheterization time were 93.3 ± 37.9 ml, 69.5 ± 39.5 min, and 6.5 ± 1.3 days, respectively. The mean International Prostate Symptom Score, quality of life score, maximum urinary flow rate, and post-void residual urine volume changed notably at 6-month follow-up (22.5 ± 6.9 vs 6.1 ± 3.2, 4.8 ± 1.3 vs 1.1 ± 0.9, 7.3 ± 4.5 vs 18.9 ± 7.1 ml s−1, and 148.7 ± 168.7 vs 28.4 ± 17.9 ml). Two (3.9%) patients required blood transfusion perioperatively, while 3 (5.9%) patients experienced transient hematuria postoperatively, and 2 (3.9%) patients received 3 days recatheterization due to clot retention. TmLRP-TT is a safe and effective minimally invasive technique for patients with previously negative transrectal prostate biopsy during the 6-month follow-up. This promising technology may be a feasible surgical method for previously negative transrectal prostate biopsy in the future.

Abstract
A high-density linkage map of goldfish (Carassius auratus) was constructed using RNA-sequencing. This map consists of 50 linkage groups with 8,521 SNP markers and an average resolution of 0.62 cM. Approximately 84% of markers are in protein-coding genes orthologous to zebrafish proteins. We performed comparative genome analysis between zebrafish and medaka, common carp, grass carp, and goldfish to study the genome evolution events in the Cyprinidae family. The comparison revealed large synteny blocks among Cyprinidae fish and we hypothesized that the Cyprinidae ancestor undergone many inter-chromosome rearrangements after speciation from teleost ancestor. The study also showed that goldfish genome had one more round of whole genome duplication (WGD) than zebrafish. Our results illustrated that most goldfish markers were orthologous to genes in common carp, which had four rounds of WGD. Growth-related regions and genes were identified by QTL analysis and association study. Function annotations of the associated genes suggested that they might regulate development and growth in goldfish. This first genetic map enables us to study the goldfish genome evolution and provides an important resource for selective breeding of goldfish.

Abstract
OBJECTIVE To study the MRI features of ventricular system tuberculosis. METHODS Nineteen patients with ventricular system tuberculosis in our hospital from Mar. 2009 to Sep. 2014 were retrospectively identified. Their clinical features and cranial MRI characteristics were reviewed. RESULTS There were 13 males and 6 females, aged from 15-81 years(mean 37±16). Eight patients had intraventricular tuberculosis, with 5 long striped or irregular shaped intraventricular tuberculosis and 3 with ventricular tuberculoma. Six patients had tubercular ependymitis and 5 had intraventricular tuberculosis along with tubercular ependymitis. The lesions of 14 patients were in the lateral ventricle; 13 in occipital or temporal horn of lateral ventricle, 9 complicated by tubercular meningitis, and 10 complicated by brain tuberculoma. The lesion of 5 patients were in the fourth ventricle, 5 in the postmedian of the fourth ventricle, 5 complicated by tubercular meningitis and 4 complicated by hydrocephalus. There were 4 cases with ring-enhancement and 15 with heterogeneous enhancement. Ten cases were complicated by peripheral edema. CONCLUSIONS The diagnosis of ventricle system tuberculosis is difficult due to its low incidence. The site, cranial MRI characteristics, the patterns of enhancement and complications have certain specificity and are useful in the diagnosis of ventricular system tuberculosis.

Abstract
OBJECTIVE To evaluate the effect and double-J stent indwelling time in the treatment of acute upper urinary tract infection caused by ureteral calculi. METHODS A prospective non-randomized controlled study was carried out. From January 2011 to August 2015, a total of 142 patients treated in Department of Urology of Shanghai First People's Hospital for ureteral calculi with systematic inflammatory response syndrome were divided into double-J stent indwelling 7 days group (n=63) and double-J stent indwelling > 7 days group (n=79). The preoperative routine blood test, urinalysis, and urine culture, the urinalysis and urine culture immediately after double-J indwelling, and the routine blood test, urinalysis, and urine culture 7 days after indwelling were compared between the two groups. Postoperative complications after lithotripsy were analyzed. RESULTS There were no statistically significant differences in preoperative blood white blood cell (WBC) count, urine WBC count, and positive bacterial culture between the two groups (all P>0.05). Seven days after double-J stent indwelling, significant improvement was seen in both the 7 d group and the >7 d group in blood WBC count, urine WBC count, and positive urine culture [(8.1±1.7) vs (14.8±3.1) ×10(9)/L, (356±44) vs (3 077±643)/μl, 1.6% vs 52.4%; (7.9±1.1) vs (15.1±3.8) ×10(9)/L, (363±52) vs (3 122±805)/μl, 3.8% vs 48.1%], and infection was managed effectively, while no statistically significant inter-group differences were observed. There was no significant difference in stone clearance rate between the two groups (96.8% vs 96.2%, P>0.05). There was no significant difference in the incidence of postoperative complications, especially infectious complications (all P>0.05). CONCLUSIONS Indwelling double-J stents for 7 days could effectively manage the infection in patients with acute upper urinary tract infection secondary to ureteral calculi. These patients can be treated with lithotripsy safely. The time of double-J stent indwelling could be shortened.

Abstract
MOTIVATION Recovering the gene structures is one of the important goals of genome assembly. In low-quality assemblies, and even some high-quality assemblies, certain gene regions are still incomplete; thus, novel scaffolding approaches are required to complete gene regions. RESULTS We developed an efficient and fast genome scaffolding method called PEP_scaffolder, using proteins to scaffold genomes. The pipeline aims to recover protein-coding gene structures. We tested the method on human contigs; using human UniProt proteins as guides, the improvement on N50 size was 17% increase with an accuracy of ∼97%. PEP_scaffolder improved the proportion of fully covered proteins among all proteins, which was close to the proportion in the finished genome. The method provided a high accuracy of 91% using orthologs of distant species. Tested on simulated fly contigs, PEP_scaffolder outperformed other scaffolders, with the shortest running time and the highest accuracy.

Abstract
The aim of this study is to compare the clinical efficacy and safety of retroperitoneal laparoscopic ureterolithotomy (RPLU) and ureteroscopic holmium laser lithotripsy (UHLL) as two minimally invasive procedures in managing obstructive upper ureteral calculi with concurrent urinary tract infections (UTI). The retrospective study included 189 patients who underwent unilateral obstructive upper ureteral stones with concurrent UTI from January 2007 to November 2014 at our institution. Patients received RPLU (81 cases) or UHLL (108 cases). All patients received preoperative anti-infection treatment (indwelling ureteral stent and/or preoperative antibiotics). Collected data, including sex, age, stone size, success rate, operation duration, post-operation hospitalization time, and post-operation complications, were compared. All patients were followed up for more than 6 months after surgeries, and no ureterostenosis occurred. The study included 189 patients, 41 (21.7 %) females and 148 (78.3 %) males with a medium age of 52 years (range 22-81 years). All surgeries were successfully performed without conversion to open surgery. Stone size in the RPLU group was larger than that of the UHLL group (16.1 ± 1.4 vs. 10.4 ± 1.6 mm, P = 0.012). Operative duration (P = 0.009) and hospitalization time (P < 0.001) in the UHLL group were significantly shorter than those in the RPLU group, whereas stone clearance rate was significantly higher in the RPLU group (100 vs. 88.9 %, P = 0.002). Of note, postoperative fever was more common in patients treated with UHLL (15 cases) versus RPLU (4 cases) (13.9 vs. 4.9 %, P = 0.043). Moreover, in the UHLL group, three patients without a preoperative indwelling ureteral stent were complicated with sepsis, which was not seen in RPLU group. In our study, the safety and stone clearance rate of RPLU are better than those of UHLL in the treatment of unilateral upper ureteric calculi with concurrent UTI. Preoperative antibiotics and indwelling ureteral stent may reduce the risk of postoperative infections.

Abstract
Well-aligned ZnO nanorods have been prepared on p-GaN-sapphire using a vapor phase transport (VPT) technique. A thin sputtered layer of TaOx is employed as the intermediate layer and an n-ZnO-TaOx-p-GaN heterojunction device has been achieved. The current transport of the heterojunction exhibited a typical resistance switching behavior, which originated from the filament forming and breaking in the TaOx layer. Color controllable electroluminescence (EL) was observed from the biased heterojunction at room temperature. Bluish-white wide band emission is achieved from the forward biased device in both the high resistance and low resistance states, while red emission can only be observed for the reverse biased device in the low resistance state. The correlation between the EL and resistance switching has been analyzed in-depth based on the interface band diagram of the heterojunction.

Abstract
Immune-related miRNAs in breast milk are extracellular miRNAs that are related to immune organ development and regulation of the immune function in infants and young animals. The goal of this study was to compare the expression levels of five immune-related miRNAs in breast milk in black goats, humans, and dairy cattle. The miRNAs from milk were extracted and the expression levels were assessed using quantitive RT-PCR methods. MiR-146, miR-155, miR-181a, miR-223, and miR-150 were all detected in Dazu black goat milk, and these miRNAs were significantly more highly expressed in colostrum than in mature milk of goats (P < 0.01), except for miR-150. Further, all five miRNAs were expressed in human colostrum, but patterns differed from those in goats: miR-146 and miR-155 were highly expressed (P < 0.01) in human colostrum, whereas miR-223 was abundant in goat colostrum (P < 0.01). In addition, five miRNAs were significantly higher in bovine mature milk than in goat milk (P < 0.01). Taken together, these results confirm that immune-related miRNAs are rich in breast milk with different expression levels depending on the lactation phase and species.

Abstract
Teleosts have more types of chromatophores than other vertebrates and the genetic basis for pigmentation is highly conserved among vertebrates. Therefore, teleosts are important models to study the mechanism of pigmentation. Although functional genes and genetic variations of pigmentation have been studied, the mechanisms of different skin coloration remains poorly understood. The koi strain of common carp has various colors and patterns, making it a good model for studying the genetic basis of pigmentation. We performed RNA-sequencing for red skin and white skin and identified 62 differentially expressed genes (DEGs). Most of them were validated with RT-qPCR. The up-regulated DEGs in red skin were enriched in Kupffer's vesicle development while the up-regulated DEGs in white skin were involved in cytoskeletal protein binding, sarcomere organization and glycogen phosphorylase activity. The distinct enriched activity might be associated with different structures and functions in erythrophores and iridophores. The DNA methylation levels of two selected DEGs inversely correlated with gene expression, indicating the participation of DNA methylation in the coloration. This expression characterization of red-white skin along with the accompanying transcriptome-wide expression data will be a useful resource for further studies of pigment cell biology.

Abstract
Common carp is a widely cultivated fish with longer than 2,000 years domestication history, due to its strong environmental adaptabilities, especially hypoxia tolerance. The common carp genome has experienced a very recent whole genome duplication (WGD) event. Among a large number of highly similar duplicated genes, a pair of Ras-associated binding-GTPase 1a (Rab1a) genes were found fast diverging. Four analogous Rab1a genes were identified in the common carp genome. Comparisons of gene structures and sequences indicated Rab1a-1 and Rab1a-2 was a pair of fast diverging duplicates, while Rab1a-3 and Rab1a-4 was a pair of less diverged duplicates. All putative Rab1a proteins shared conserved GTPase domain, which enabled the proteins serve as molecular switches for vesicular trafficking. Rab1a-1 and Rab1a-2 proteins varied in their C-terminal sequences, which were generally considered to encode the membrane localization signals. Differential expression patterns were observed between Rab1a-1 and Rab1a-2 genes. In blood, muscle, spleen, and heart, the mRNA level of Rab1a-1 was higher than that of Rab1a-2. In liver and intestine, the mRNA level of Rab1a-2 was higher. Expression of Rab1a-1 and Rab1a-2 showed distinct hypoxia responses. Under severe hypoxia, Rab1a-1 expression was down-regulated in blood, while Rab1a-2 expression was up-regulated in liver. Compared with the less diverged Rab1a-3/4 gene pair, common carp Rab1a-1/2 gene pair exhibited strong characteristics of sub-functionalization, which might contribute to a sophisticated and efficient Ras-dependent regulating network for the hypoxia-tolerant fish.
