Abstract
The bony window technique refers to cutting the intact bone plate to form a bone window and a free bone block to get access to lesions under the bone. At the end of the surgery, the dislocated bony lid needs to be repositioned to its original position. In endodontic microsurgery, compared with conventional osteotomy, the bony window technique has the advantages of improving the view of surgery and operability, reducing postoperative bone defects, promoting bone healing, and maintaining the integrity of the jaw outline. Accurate positioning and preparation of the bony window are important prerequisites for subsequent operations during the surgery, but it's difficult in some situations, such as when the operative area is located posteriorly or the bone cortex on the lesion surface is thick and intact. What's more, whether the free bone block can be stabilized in situ after repositioning is closely related to the prognosis of the surgery. The complementary application of digital navigation technology and bone cavity filling materials may help to improve the bony window technique and provide more possibilities for the retention of affected teeth in difficult cases.

Abstract
PURPOSE We present a novel technique for intraocular lens (IOL) fixation. The technique can be used on single-piece acrylic IOLs and can manage the patients who are either aphakia or with a dislocated IOL. METHODS One end of Gore-Tex suture is tied into the optic-haptic junction of the IOL. Another end is fixated in the scleral wall. The single sclerotomy and double sclerotomies settings can be applied to different situations. RESULTS Twelve eyes received this procedure. After a follow-up period of up to 20 months, the IOLs were well centered. CONCLUSION The technique is a reliable method for scleral fixation of IOLs, which can be applied on the widely used single-piece acrylic IOLs. In our experience, it is reproducible and rarely cause complications.

Abstract
Objective: To investigate the effects of combined blockade of interleukin-33 (IL-33) and inducible co-stimulatory molecule (ICOS) on carbon tetrachloride-induced chronic liver fibrosis and imbalance of T helper lymphocyte subsets in mice. Methods: There were 40 BALB/c mice in each model and control group. Flow cytometry was used to determine the proportion of Th1/Th2/Th17 cells in the splenic lymphocyte suspension of mice, the expression levels of interferon γ, IL-4, and IL-17 in the splenic lymphocyte suspension of liver fibrosis mice after combined blockade of IL-33 and ICOS, and the pathological changes of liver histopathology in mice with liver fibrosis. Two independent sample t-test was used to compare data between groups. Results: Compared with the non-blocking group, the proportion of Th2 and Th17 cells in the IL-33/ICOS blocking group was significantly down-regulated (Th2: 65.96% ± 6.04% vs. 49.09% ± 7.03%; Th17: 19.17% ± 4.03% vs. 9.56% ± 2.03%), while the proportion of Th1 cells and Th1/Th2 ratio were up-regulated (Th1: 17.14% ± 3.02% vs. 31.93% ± 5.02%; Th1/Th2: 0.28 ± 0.06 vs. 0.62 ± 0.23), and the difference was statistically significant (t = 5.15, 6.03, 7.14, 4.28, respectively, with P < 0.05). After entering the chronic inflammation stage of liver fibrosis in mice (10 weeks), compared with the non-blocking group, the expression levels of IL-4 and IL-17 in the blockade group were significantly down-regulated [IL-4: (84.75 ± 14.35) pg/ ml vs. (77.88 ± 19.61) pg/ml; IL-17: (72.38 ± 15.13) pg/ml vs. (36.38 ± 8.65) pg/ml], while the expression of interferon γ was up-regulated [(37.25 ± 11.51) pg/ml vs. (77.88 ± 19.61) pg/ml], and the difference was statistically significant (t: IL-4: 4.71; IL-17: 5.84; interferon γ: 5.05, respectively, with P < 0.05). Liver histopathological results showed that hepatic necrosis, hepatic lobular structural disorder, and fibrous tissue hyperplasia were significantly lower in the blockade group than those in the non-blocking group at 13 weeks of liver fibrosis. Conclusion: Combined blockade of the ICOS signaling pathway and IL-33 can regulate Th2 and Th17 polarization, down-regulate the inflammatory response, and inhibit or prevent the occurrence and progression of fibrosis.

Abstract
Objective: To analyze the factors associated with readmission within three months of surgery for gastric cancer and the impact of readmission on patients' long-term nutritional status and quality of life. Methods: This was a prospective cohort study comprising patients who underwent radical gastrectomy in the Department of Pancreatic and Gastric Surgery, National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences from October 2018 to August 2019. Patients who failed to complete postoperative follow-up, whose body mass index (BMI) could not be accurately estimated, or who were unable to complete a quality-of-life questionnaire were excluded. The patients were followed up for 12 months. Time to, cause(s) of, and outcomes of readmission were followed up 1, 2 and 3 months postoperatively. BMI was followed up 1, 3, 6 and 12 months postoperatively. Results of blood tests were collected and patients' nutritional status and quality of life were assessed 12 months postoperatively. Nutritional status was evaluated by BMI, hemoglobin, albumin, and total lymphocyte count. Quality of life was evaluated using the European Organization for Research in the Treatment of Cancer (EORTC) Quality of Life scale. The higher the scores for global health and functional domains, the better the quality of life, whereas the higher the score in the symptom domain, the worse the quality of life. Results: The study cohort comprised 259 patients with gastric cancer, all of whom were followed up for 3 months and 236 of whom were followed up for 12 months. Forty-four (17.0%) patients were readmitted within 3 months. The commonest reasons for readmission were gastrointestinal dysfunction (16 cases, 36.3%), intestinal obstruction (8 cases, 18.2%), and anastomotic stenosis (8 cases, 18.2%). Logistic regression analysis showed that preoperative Patient-Generated Subjective Global Assessment score ≥ 4 points (OR=1.481, 95% CI: 1.028‒2.132), postoperative complications (OR=3.298, 95%CI:1.416‒7.684) and resection range (OR=1.582, 95% CI:1.057‒2.369) were risk factors for readmission within 3 months of surgery. Compared with patients who had not been readmitted 12 months after surgery, patients who were readmitted within 3 months of surgery tended to have greater decreases in their BMI [-2.36 (-5.13,-0.42) kg/m2 vs. -1.73 (-3.33,-0.33) kg/m2, Z=1.850, P=0.065), significantly lower hemoglobin and albumin concentrations [(122.1±16.6) g/L vs. (129.8±18.4) g/L, t=2.400, P=0.017]; [(40.9±5.0) g/L vs. (43.4±3.3) g/L, t=3.950, P<0.001], and significantly decreased global health scores in the quality of life assessment [83 (67, 100) vs. 100 (83, 100), Z=2.890,P=0.004]. Conclusion: Preoperative nutritional risk, total or proximal radical gastrectomy, and complications during hospitalization are risk factors for readmission within 3 months of surgery for gastric cancer. Perioperative management and postoperative follow-up should be more rigorous. Readmission within 3 months after surgery may be associated with a decline in long-term nutritional status and quality of life. Achieving improvement in long-term nutritional status and quality of life requires tracking of nutritional status, timely evaluation, and appropriate interventions in patients who need readmission.

Abstract
While radium (Ra)-223 is among the multiple, known life-prolonging treatments in bone-predominant metastatic castration-resistant prostate cancer (mCRPC), optimal treatment sequencing has not been determined, particularly in the Asia-Pacific context. Hence, we aimed to compare treatment outcomes of docetaxel-naïve and post-docetaxel mCRPC patients undergoing Ra-223 therapy in Taiwan. Using a single-center retrospective cohort design, we reviewed records of adult patients receiving Ra-223 for bone-metastatic mCRPC from 2018 to 2021. Patients were categorized into docetaxel-naïve or post-docetaxel groups based on history of docetaxel use preceding Ra-223. We compared the 2 groups in terms of all-cause death, 6-cycle treatment completion, and the following secondary outcomes: pain control, change in biochemical parameters (prostate-specific antigen, lactate dehydrogenase, alkaline phosphatase), biochemical response, and treatment-emergent adverse events. We performed total population sampling and a complete case analysis. We included 48 patients (25 docetaxel-naïve, 23 post-docetaxel) in the study. The mean follow-up duration was 12.4 months for the entire cohort. The docetaxel-naïve group exhibited a significantly lower all-cause mortality rate versus the post-docetaxel group (40.0% vs 78.3%, P = .02), as well as a significantly higher treatment completion rate (72.0% vs 26.1%, P < .01). We did not find significant differences in pain control, change in biochemical parameters, biochemical response, or hematologic treatment-emergent adverse events between the 2 groups. However, the docetaxel-naïve group had a numerically higher pain control rate, numerically greater improvements in alkaline phosphatase and prostate-specific antigen, and numerically lower rates of grade ≥ 3 neutropenia and grade ≥ 3 thrombocytopenia than the post-docetaxel group. Use of Ra-223 in docetaxel-naïve patients with mCRPC led to lower mortality and higher treatment completion than post-docetaxel use. Our study adds preliminary real-world evidence that Ra-223 may be used safely and effectively in earlier lines of treatment for bone-predominant mCRPC. Further large-scale, longer-term, and controlled studies are recommended.

Abstract
BACKGROUND We tested the hypothesis that overexpression of cellular-prion-protein in adipose-derived mesenchymal stem cells (PrPCOE-ADMSCs) effectively protected the kidney against ischemia-reperfusion (IR) injury in rat. METHODS Part I of cell culture was categorized into A1(ADMSCs)/A2(ADMSCs+p-Cresol)/A3(PrPCOE in ADMSCs)/A4 (PrPCOE in ADMSCs+p-Cresol). Part II of cell culture was divided into B1(ADMSCs)/B2[ADMSCs+lipopolysaccharide (LPS)]/B3(PrPCOE in ADMSCs)/B4(PrPCOE in ADMSCs+LPS). Sprague-Dawley (SD) rats (n = 50) were equally categorized into groups 1 (sham-operated-control)/2 (IR)/3 (IR+ADMSCs/6.0 × 105 equally divided into bilateral-renal arteries and 6.0 × 105 intravenous administration by 1 h after IR)/4 [IR+PrPCOE-ADMSCs (identical dosage administered as group 3)]/5 [IR+silencing PRNP -ADMSCs (identical dosage administered as group 3)], and kidneys were harvested post-day 3 IR injury. RESULTS Part I results demonstrated that the cell viability at 24/48/72 h, BrdU uptake/number of mitDNA/APT concentration/mitochondrial-cytochrome-C+ cells and the protein expressions of ki67/PrPC at 72 h-cell culturing were significantly higher in PrPCOE-ADMSCs than in ADMSCs (all P < 0.001). The protein expressions of oxidative-stress (NOX-1/NOX2/NOX4/oxidized protein)/mitochondrial-damaged (p22-phox/cytosolic-cytochrome-C)/inflammatory (p-NF-κB/IL-1ß/TNF-α/IL-6)/apoptotic (cleaved caspase-3/cleaved-PARP) biomarkers were lowest in A1/A3 and significantly higher in A2 than in A4 (all P < 0.001). Part II result showed that the protein expressions of inflammatory (p-NF-κB/IL-1ß/TNF-α/IL-6)/apoptotic (cleaved caspase-3/cleaved-PARP) biomarkers exhibited an identical pattern of part I among the groups (all P < 0.001). The protein expressions of inflammatory (p-NF-κB/IL-1ß/TNF-α/MMP-9)/oxidative-stress (NOX-1/NOX-2/oxidized-protein)/mitochondrial-damaged (cytosolic-cytochrome-C/p22-phox)/apoptotic (cleaved caspase-3/cleaved-PARP/mitochondrial-Bx)/autophagic (beclin-1/ratio of LC3B-II/LC3B-I)/fibrotic (Smad3/TGF-ß) biomarkers and kidney-injury-score/creatinine level were lowest in group 1, highest in group 2, significantly higher in group 5 than in groups 3/4 (all P < 0.0001). CONCLUSION PrPCOE in ADMSCs rejuvenated these cells and played a cardinal role on protecting the kidney against IR injury.

Abstract
Insects comprise more than a million species and many authors have attempted to explain this success by evolutionary innovations. A much overlooked evolutionary novelty of insects is the serosa, an extraembryonic epithelium around the yolk and embryo. We have shown previously that this epithelium provides innate immune protection to eggs of the beetle Tribolium castaneum. It remained elusive, however, whether this immune competence evolved in the Tribolium lineage or is ancestral to all insects. Here, we expand our studies to two hemimetabolous insects, the bug Oncopeltus fasciatus and the swarming grasshopper Locusta migratoria. For Oncopeltus, RNA sequencing reveals an extensive response upon infection, including the massive upregulation of antimicrobial peptides (AMPs). We demonstrate antimicrobial activity of these peptides using in vitro bacterial growth assays and describe two novel AMP families called Serosins and Ovicins. For both insects, quantitative polymerase chain reaction shows immune competence of the eggs when the serosa is present, and in situ hybridizations demonstrate that immune gene expression is localized in the serosa. This first evidence from hemimetabolous insect eggs suggests that immune competence is an ancestral property of the serosa. The evolutionary origin of the serosa with its immune function might have facilitated the spectacular radiation of the insects. This article is part of the theme issue 'Extraembryonic tissues: exploring concepts, definitions and functions across the animal kingdom'.

Abstract
PurposeTo evaluate the prognostic impact of the lowest level of tumor location for upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU).Materials and methodsData were collected from patients with UTUC treated with RNU (01/2005- 06/2020) at a single center in Taiwan. Patients were stratified by the lowest level of tumor location into three groups: renal pelvis only (RPO), above upper ureter (AUU), and below upper ureter (BUU). We compared characteristics between groups and examined the association of the lowest level of tumor involvement with intravesical recurrence (IVR), systemic metastasis (SM), and cancer-specific mortality (CSM).ResultsOverall, 1239 patients (542 RPO, 260 AUU, 437 BUU) were enrolled. Concurrent bladder cancer, multifocality, tumor architecture, lymphovascular invasion, carcinoma in situ, and variant histology were significantly different across different tumor locations. BUU had worse five-year intravesical recurrence (IVR), systemic metastasis (SM) and cancer-specific mortality (CSM) (p < 0.001, p = 0.056 and p = 0.13, respectively). In multivariable models, the lowest level of tumor involvement was an independent predictor of IVR (AUU hazard ratio (HR) = 1.52, p = 0.007; BUU HR = 1.75, p < 0.001), but only BUU was an independent predictor of SM (HR = 1.61, p = < 0.001) and CSM (HR = 1.51, p = 0.008).ConclusionThe lowest level of tumor involvement in UTUC, especially BUU, was associated with a higher risk of IVR, SM and CSM. Assessment of the lowest level of tumor involvement after RNU may help identify patients who require more intensive follow-up.

Abstract
We introduced a novel surgery that combines ultrasound guidance, miniaturization and Galdakao-modified supine Valdivia (GMSV) position in percutaneous nephrolithotomy (PCNL) and evaluated the safety and efficacy. This retrospective, single-center study retrospectively reviewed 150 patients who underwent ultrasound-guided mini-PCNL in the GMSV position from November 2019 to March 2022. All perioperative parameters were collected. Stone-free status was defined as no residual stones or clinically insignificant residual fragments (CIRF) <0.4 cm on postoperative day one. Among the 150 patients, the mean age was 56.96 years. The mean stone size was 3.19 cm (427 mm2). The mean S.T.O.N.E. score was 7.61, including 36 patients (24%) with scores ≥9. The mean operative time was 66.22 min, and the success rate of renal access creation in the first attempt was 88.7%. One hundred and forty (93.3%) patients were stone free. The mean decrease in Hemoglobin was 1.04 g/dL, and no patient needed a blood transfusion. Complications included transient hematuria (n = 13, 8.7%), bladder blood clot retention (n = 2, 1.3%), fever (n = 15, 10%) and sepsis (n = 2, 1.3%). Totally X-ray-free ultrasound-guided mini-PCNL in the GMSV position is feasible, safe and effective for patients with upper urinary tract stones, indicating the synergistic and complementary effects of the three novel techniques.

Abstract
Objective: To analyze and evaluate the differences in sex hormones after laparoscopic Roux-en-Y Gastric Bypass Surgery (LRYGB) and laparoscopic sleeve gastrectomy (LSG) in male patients with obesity. Methods: This study was a retrospective cohort study. The inclusion criteria were (1) male patients with obesity who met the surgical indications of the "Chinese Guidelines for Surgical Treatment of Obesity and Type 2 Diabetes" (2019 Edition); (2) patients with a body mass index (BMI) of ≥27.5 kg/m2 and obesity-related metabolic diseases, or patients with severe obesity and a BMI of ≥35 kg/m2; and (3) sex hormone levels checked 1 year after surgery. The exclusion criteria included (1) patients with endocrine diseases (thyrotoxicosis, hyperprolactinemia) and hypothalamic-pituitary lesions and (2) those with severe major organ dysfunction who could not tolerate anesthesia or surgery. According to the above criteria, the clinical data of male patients with obesity admitted to the Gastrointestinal Surgery/Bariatric Center of the First Affiliated Hospital of Jinan University from October 2017 to January 2020 were included. A total of 52 male patients with obesity were included in this study. The mean age, body weight, BMI, and total testosterone level were (29.3±10.2) years, (123.6±35.4) kg, (40.1±11.1) kg/m2, and 7.6 (5.5, 9.1) nmol/L, respectively. Forty-five patients (86.5%) exhibited testosterone deficiency. Among all the patients, 29 underwent LSG (LSG group) and 23 underwent LRYGB surgery (LRYGB group). The main outcome measure was the change in sex hormone levels before and after bariatric surgery in all the patients. The secondary outcome measures were the comparison of changes in sex hormone levels before and after LSG and LRYGB. Results: Pearson correlation analysis showed that preoperative estradiol was positively correlated with waist circumference (R=0.299, P<0.05), hip circumference (R=0.326, P<0.05), and chest circumference (R=0.388, P<0.05). Testosterone was negatively correlated with BMI (R=-0.563, P<0.01), waist circumference (R=-0.521, P<0.01), hip circumference (R=-0.456, P<0.01), chest circumference (R=-0.600, P<0.01), and neck circumference (R=-0.547, P<0.01). One year following bariatric surgery, the serum testosterone (7.6 [5.5, 9.1] nmol/L vs. 13.6 [10.5, 15.4] nmol/L, Z=-5.910, P<0.001), follicle-stimulating hormone (4.7 [2.7, 5.3] IU/L vs. 6.5 [3.6, 7.8] IU/L, Z=-4.658, P<0.001), and progesterone (1.2 [0.4, 1.5] nmol/L vs. 1.9 [0.8, 1.3] nmol/L, Z=-2.542, P=0.011) levels were significantly higher in all the patients. Both estradiol (172.8 [115.6, 217.5] pmol/L vs. 138.3 [88.4, 168.1] pmol/L, Z=-2.828, P=0.005) and prolactin (11.4 [6.4, 14.6] mIU/L vs. 8.6 [4.8, 7.3] mIU/L, Z=-2.887, P=0.004) levels were decreased. In addition to prolactin levels in the LRYGB group, there were statistically significant differences in the levels of estradiol (P=0.030), follicle-stimulating hormone (P < 0.001), luteinizing hormone (P=0.033), progesterone (P=0.034), and testosterone (P<0.001) compared with their preoperative levels. In the LSG group, there were statistically significant differences in the levels of follicle-stimulating hormone (P=0.011), prolactin (P=0.023), and testosterone (P<0.001) compared with their preoperative levels. Conclusion: The degree of obesity in men was negatively correlated with testosterone levels. Both LRYGB and LSG can significantly improve sex hormone levels in male patients with obesity, and testosterone levels show a significant increase after surgery.

Abstract
Objective: To translate the English version of the non-alcoholic fatty liver disease quality of life scale (CLDQ-NAFLD) into the Chinese version in order to test its reliability and validity. Methods: The English version of the CLDQ-NAFLD was translated according to the cross-cultural research tool debugging and validation guidelines to form the Chinese version of the CLDQ-NAFLD. A questionnaire survey was conducted on 515 NAFLD cases in a tertiary hospital in Hangzhou from September 2021 to April 2022 to evaluate the reliability and validity of the scale. Results: The Chinese version of the CLDQ-NAFLD contained six domains with a total of thirty-six items (X2/DF=3.105, RMSEA=0.064, TLI=0.905, CFI=0.912, and IFI=0.913). I-CVI, S-CVI/UA, and S-CVI/Ave was 0.83 to 1.00, 0.86 and 0.98, respectively. The 12-item Short-Form Health Survey (SF-12) was used as the calibration standard, and the correlation validity of the calibration standard was 0.704 (P<0.001). The Cronbach's alpha coefficient of the total scale and each dimension of the scale was 0.964 and 0.807-0.956, respectively. The test-retest reliability was 0.839. Conclusion: The Chinese version of the CLDQ-NAFLD has good reliability and validity. Thus, it can be used to evaluate the quality of life for NAFLD patients with a Chinese cultural background.

Abstract
Objective: To explore whether apatinib can reverse the chemotherapy resistance of patients with advanced sarcoma. Methods: The clinical data of advanced sarcoma patients after chemotherapy who received the original chemotherapy regimen combined with low-dose apatinib in Cancer Center of Union Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology from May 2018 to November 2021 were collected retrospectively to evaluate the efficacy and safety of this regimen. The primary end point was progression-free survival (PFS), and the secondary end points were objective response rate (ORR), disease control rate (DCR), overall survival (OS) and adverse events (AE). The patients were grouped according to the diagnosis: osteosarcoma, soft tissue sarcoma and undifferentiated small round cell sarcoma. And the benefits of combination treatment was investigated with the stratified analysis of best outcome of combined therapy, lines of chemotherapy received, best response and PFS of original chemotherapy. Results: A total of 30 patients were included in this study, including 20 males and 10 females. The mean age was (25.6±14.7) years. There were 9 cases of osteosarcoma, 11 cases of soft tissue sarcoma and 10 cases of undifferentiated small round cell sarcoma. No patient achieved complete response, 8 patients (26.7%) achieved partial response, 19 patients (63.3%) achieved disease stability, the ORR was 26.7%(8/30), and the DCR was 90.0%(27/30). The median PFS and OS were 4.1 and 13.1 months respectively. Among the three different subtypes of sarcoma, the ORR of osteosarcoma was 44.4% (4/9), the median PFS was 4.1 months, and the median OS was not yet achieved; the ORR of undifferentiated small round cell sarcoma was 40% (4/10), the median PFS was 6.4 months, and the median OS was 10.9 months; No response was observed in soft tissue sarcoma, and the median PFS and median OS was 3.5 and 7.3 months respectively. Patients who achieved objective response had better PFS than patients with stable disease (12.8 vs 3.8 months, P=0.015), and patients with PFS≥ 6 months of original chemotherapy had better PFS benefits (12.7 vs 2.7 months, P<0.001). However, the number of original chemotherapy lines and the best response of original chemotherapy had no significant effect on the PFS of this combination regimen. In terms of safety, the related toxicity of apatinib was no more than grade 2, and the grade 4 chemotherapy-related adverse reactions was mainly hematological toxicity, of which 2 patients interrupted treatment because of febrile neutropenia. Conclusion: Low dose apatinib is effective in reversing chemotherapy resistance of osteosarcoma and undifferentiated small round cell sarcoma with acceptable adverse reactions.

Abstract
The role of miRNAs in cancer and their possible function as therapeutic agents are interesting and needed further investigation. The miR-26a-5p had been demonstrated as a tumor suppressor in various cancers. However, the importance of miR-26a-5p regulation in upper tract urothelial carcinoma (UTUC) remains unclear. Here, we aimed to explore the miR-26a-5p expression in UTUC tissues and to identify its regulatory targets and signal network involved in UTUC tumorigenesis. The miR-26a-5p expression was validated by quantitative real-time polymerase chain reaction (qPCR) using renal pelvis tissue samples from 22 patients who were diagnosed with UTUC and 64 cases of renal pelvis tissue microarray using in situ hybridization staining. BFTC-909 UTUC cells were used to examine the effects of miR-26a-5p genetic delivery on proliferation, migration and expression of epithelial-to-mesenchymal transition (EMT) markers. MiR-26a-5p was significantly down-regulated in UTUC tumors compared to adjacent normal tissue and was decreased with histological grades. Moreover, restoration of miR-26a-5p showed inhibition effects on proliferation and migration of BFTC-909 cells. In addition, miR-26a-5p delivery regulated the EMT marker expression and inhibited WNT5A/β-catenin signaling and expression of downstream molecules including NF-κB and MMP-9 in BFTC-909 cells. This study demonstrated that miR-26a-5p restoration may reverse EMT process and regulate WNT5A/β-catenin signaling in UTUC cells. Further studies warranted to explore the potential roles in biomarkers for diagnostics and prognosis, as well as novel therapeutics targets for UTUC treatment.

Abstract
Background The unusual high dialysis prevalence and upper urinary tract urothelial carcinoma (UTUC) incidence in Taiwan may attribute to aristolochic acid (AA), which is nephrotoxic and carcinogenic, exposure. AA can cause a unique mutagenic pattern showing A:T to T:A transversions (mutational Signature 22) analyzed by whole exome sequencing (WES). However, a fast and cost-effective tool is still lacking for clinical practice. To address this issue, we developed an efficient and quantitative platform for the quantitation of AA and tried to link AA detection with clinical outcomes and decipher the genomic landscape of UTUC in Taiwan. Patients and Methods We recruited 61 patients with de novo onset of UTUC after kidney transplantation who underwent radical nephroureterectomy. A liquid chromatography-tandem mass spectrometry (LC-MS/MS) platform was developed for the quantitation of AA. Pearson’s chi-square test, Kaplan–Meier method, and Cox proportional hazard model were utilized to assess the correlations among AA detection, clinicopathological characteristics, and clinical outcomes. Seven tumors and seven paired normal tissues were sequenced using WES (approximately 800x sequencing depth) and analyzed by bioinformatic tool. Results We found that high level of 7-(deoxyadenosin-N6-yl)aristolactam I (dA-AL-I) detected in paired normal tissues was significantly correlated with fast UTUC initiation times after renal transplantation (p = 0.035) and with no use of sirolimus (p = 0.046). Using WES analysis, we further observed that all tumor samples were featured by Signature 22 mutations, apolipoprotein B mRNA-editing enzyme, catalytic polypeptide (APOBEC)-associated gene mutations, p53 mutations, no fibroblast growth factor receptor 3 (FGFR3) mutation, and high tumor mutation burden (TMB). Especially, mammalian target of rapamycin (mTOR) activation predominated in dA-AL-I-detected samples compared with those without dA-AL-I detection and might be associated with UTUC initiation through cell proliferation and suppression of UTUC progression via autophagy inhibition. Conclusion Accordingly, dA-AL-I detection can provide more direct evidence to AA exposure and serve as a more specific predictive and prognostic biomarker for patients with de novo onset of UTUC after kidney transplantation.

Abstract
Cardiac endothelial cells (ECs) are important targets for cardiovascular gene therapy. However, the approach of stably transducing ECs in vivo using different vectors, including adeno-associated virus (AAV), remains unexamined. Regarding this unmet need, two AAV libraries from DNA shuffling and random peptide display were simultaneously screened in a transgenic mouse model. Cardiac ECs were isolated by cell sorting for salvage of EC-targeting AAV. Two AAV variants, i.e., EC71 and EC73, enriched in cardiac EC, were further characterized for their tissue tropism. Both of them demonstrated remarkably enhanced transduction of cardiac ECs and reduced infection of liver ECs in comparison to natural AAVs after intravenous injection. Significantly, persistent transgene expression was maintained in mouse cardiac ECs in vivo for at least 4 months. The EC71 vector was selected for delivery of the endothelial nitric oxide synthase (eNOS) gene into cardiac ECs in a mouse model of myocardial infarction. Enhanced eNOS activity was observed in the mouse heart and lung, which was correlated with partially improved cardiac function. Taken together, two AAV capsids were evolved with more efficient transduction in cardiovascular endothelium in vivo, but their endothelial tropism might need to be further optimized for practical application to cardiac gene therapy.

Abstract
Background This study tested the hypothesis that combined melatonin (Mel) and adipose-derived mesenchymal stem cells (ADMSCs) treatment was superior to either one alone on protecting the testis against acute testicular torsion-induced ischemia-reperfusion (TTIR) injury. Methods and results Male adult SD rats (n = 30) were equally categorized into group 1 (sham-operated control), group 2 [TTIR/by torsion of right/left testis (i.e., ischemia) with rotated 720° counterclockwise for 2 h, then detorsion (i.e., reperfusion) to the original position for 72 h], group 3 (TTIR + Mel/intraperitoneal administration/50 mg/kg at 30 min after ischemia, followed by 20 mg at 3 h and days 1/2/3 after TTIR), group 4 (TTIR + ADMSCs/1.2 × 106 cells/by tail-vein administration at 30 min after ischemia, followed by days 1/2 TTIR), and group 5 (TTIR + Mel + ADMSCs/tail-vein administration). The result showed that the protein expressions of oxidative-stress (NOX-1/NOX-2/oxidized-protein), apoptotic/mitochondrial-damaged (mitochondrial-Bax/cleaved-caspase3/cleaved-PARP/cytosolic-cytochrome C), and fibrotic (TGF-ß/Smad3) biomarkers as well as testicular damage scores were lowest in group 1, highest in group 2, and significantly higher in groups 3/4 than in group 5, but they showed no difference between groups 3/4, whereas the protein expressions of androgen receptor (AR) and vimentin showed an opposite pattern of oxidative stress (all p < 0.0001). The cellular levels of inflammation (MMP-9/MPO/CD68) exhibited an identical pattern, whereas the numbers of Sertoli cells, α-tubulin, AR and vimentin as well as thickness of seminiferous tubule exhibited an opposite pattern of oxidative stress among the groups (all p < 0.0001). Conclusion Mel-ADMSCs effectively protected the testis against TTIR injury.

Abstract
Preserving renal function and controlling oncological outcomes are pertinent when managing renal neoplasms. Cryoablation is the recommended treatment only for clinical T1a stage renal tumour. Here, we compared the outcomes of robot-assisted laparoscopic partial nephrectomy (RaPN) and laparoscopic cryoablation (LCA) in the treatment of patients with localised T1-T2 renal tumours. Overall, 86 patients who received RaPN and 78 patients underwent LCA were included in this study. The intraoperative, postoperative, and oncological outcomes in the LCA group were non-inferior to the RaPN group. Moreover, LCA demonstrated shorter operative time (267.45 ± 104.53 min vs. 138.56 ± 45.28 min, p < 0.001), lower blood loss (300.56 ± 360.73 mL vs. 30.73 ± 50.31 mL, p < 0.001), and slight renal function deterioration because of the reduced invasiveness, without compromising on the oncological outcomes.

Abstract
Dorsoventral pattering relies on Toll and BMP signalling in all insects studied so far, with variations in the relative contributions of both pathways. Drosophila and the beetle Tribolium share extensive dependence on Toll, while representatives of more distantly related lineages like the wasp Nasonia and bug Oncopeltus rely more strongly on BMP signalling. Here, we show that in the cricket Gryllus bimaculatus, an evolutionarily distant outgroup, Toll has, like in Drosophila, a direct patterning role for the ventral half of the embryo. In addition, Toll polarises BMP signalling, although this does not involve the conserved BMP inhibitor Sog/Chordin. Finally, Toll activation relies on ovarian patterning mechanisms with striking similarity to Drosophila. Our data suggest two surprising hypotheses: (1) that Toll's patterning function in Gryllus and Drosophila is the result of convergent evolution or (2) a Drosophila-like system arose early in insect evolution and was extensively altered in multiple independent lineages.

Abstract
BACKGROUND The risk of primary aristolochic acid (AA)-associated urothelial carcinoma (AA-UC) has been summarized by a 2013-published meta-analysis. Given that additional evidence has been continuously reported by original studies, an updated meta-analysis is needed. Meanwhile, to complete the whole picture, a systematic review of molecular alterations observed in AA-urinary tract cancers (AA-UTC) was also performed. METHODS We searched PubMed, Embase and four Chinese databases up to October 2020. Observational studies comparing risk or oncologic outcomes of UTC between patients with and without AA exposure were eligible for systematic review and meta-analysis. Studies investigating molecular alterations in AA-UTC using human tissue samples were eligible for systematic review. RESULTS In total, 38 and 20 studies were included in the systematic review and meta-analysis, respectively. Exposure to AA led to an overall increased risks of primary UTC [UC and renal cell carcinoma (RCC)] (OR 6.085, 95% CI 3.045-12.160) and postoperatively recurrent UC (RR 1.831, 95% CI 1.528-2.194). Subgroup analysis of postoperative primary AA-upper tract UC (AA-UTUC) showed increased risks of bladder recurrence (adjusted RR 1.949, 95% CI 1.462-2.597) and contralateral UTUC recurrence (crude RR 3.760, 95% CI 2.225-6.353), worse overall survival (adjusted HR 2.025, 95% CI 1.432-2.865) and worse disease-specific survival (adjusted HR 3.061, 95% CI 1.190-7.872), but no effect on cancer-specific survival (adjusted HR 0.772, 95% CI 0.269-2.215). High mutation load with AA mutational signature presenting largely in the putative driver genes was observed in AA-UTUC. In contrast, AA mutational signature is rarely found in the mutated RCC driver genes and the mutation load in AA-RCC is low. Therefore, AA has different roles in the genesis of UTUC and RCC. CONCLUSIONS Implementing effective strategies to completely protect people from exposure to AA is urgently needed. Additionally, more effort should be made in identifying the precise carcinogenic mechanisms of AA to determine the future treatment strategies. PLAIN LANGUAGE SUMMARY Risk, recurrence and survival outcomes after surgery and molecular changes possibly involved in the genesis of aristolochic acid-associated urinary tract cancers Background: The association between aristolochic acid (AA) and primary urothelial carcinoma (UC) has been summarized by a 2013-published meta-analysis. Given that additional evidence has been reported in the past 7 years, an updated meta-analysis is needed. Meanwhile, to complete the whole picture, a systematic review of molecular changes possibly involved in AA-mediated urinary tract carcinogenesis was also performed. Methods: We searched PubMed, Embase and four Chinese databases for human studies up to October 2020. Studies comparing the risk of urinary tract cancer (UTC) between patients with and without AA exposure and studies investigating the molecular changes in AA-associated UTC (AA-UTC) using human tissue samples were eligible for inclusion. Thirty-eight studies were finally included. Results: The results showed that exposure to AA was associated with a 6-fold increased risk of primary UTC (UC and renal cell carcinoma, RCC) and a 1.8-fold increased risk of postoperatively recurrent UC. After studies reporting primary AA-upper tract UC (AA-UTUC) were analyzed, a 1.9-fold increased risk of bladder recurrence and a 3.8-fold increased risk of contralateral UTUC recurrence was observed. Additionally, exposure to AA worsened the postoperative survival of patients with UTUC by a 2-fold increased risk of overall death and a 3-fold increased risk of death from other diseases and recurrences. However, there was no effect on death due to cancer. Lastly, AA seemed to play different roles in the etiology of UTUC and RCC based on the observations of different mutation loads and different distributions of AA-induced mutations in AA-UTUC and AA-RCC samples. Conclusions: Implementing effective strategies to completely protect people from exposure to AA is urgently needed. Moreover, more effort should be made in identifying the precise carcinogenic mechanisms of AA-UTC to determine the future treatment strategies.

Abstract
Objective: To investigate postoperative complications of patients undergoing neoadjuvant therapy followed by radical gastrectomy, and to analyze their influence on the prognosis. Methods: A retrospective case-control study was used. Case inclusion criteria: (1) gastric adenocarcinoma confirmed by histopathology; (2) preoperative imaging examination showed no distant metastasis or peritoneal dissemination; (3) undergoing radical gastrectomy and D2 lymph node dissection after neoadjuvant therapy; (4) complete clinicopathological and follow-up data. According to the above criteria, clinical data of 490 gastric cancer patients who underwent radical gastrectomy in the Cancer Hospital of Chinese Academy of Medical Sciences, Peking Union Medical College from January 2008 to December 2018 were retrospectively collected, including 358 males and 132 females with mean age of (55.0±10.6) years. Neoadjuvant chemotherapy regimens included SOX (S-1+ oxaliplatin, n=151), XELOX (capecitabine+oxaliplatin, n=155), FLOT (docetaxel+oxaliplatin+fluorouracil, n=66), and DOS (docetaxel+ oxaliplatin+S-1, n=68). Preoperative concurrent chemoradiotherapy was performed in 100 patients. SOX regimen was used for 2-4 cycles as induction chemotherapy plus concurrent chemoradiotherapy (3D IMRT+S-1). Postoperative complications were defined as surgery-related complications, mainly including hemorrhage, anastomotic leakage, obstruction, anastomotic stenosis, pulmonary infection, abdominal infection, etc. Postoperative complications were graded according to Clavien-Dindo classification. Log-rank test and Cox regression model were used for univanriate multivariate prognostic analysis, respectively. Results: A total of 101 complications ocaured after operation in 87 (17.8%) patients, including 29 cases of major complications (Clavien-Dindo III to V), and 58 cases of minor complications (Clavien-Dindo I to II). Multivariate analysis showed that age > 65 years (HR=3.077, 95% CI: 1.827-5.184, P<0.001) and total gastrectomy (HR=1.735, 95% CI: 1.069-2.814, P=0.026) were independent risk factors for postoperative complications in patients with gastric cancer undergoing neoadjuvant therapy and radical gastrectomy (both P<0.05). The follow-up period was 0.7 to 131.8 months (median 21.5 months), and the 5-year overall survival rate was 47.4%. The 5-year overall survival rates of the complication group (87 cases) and the non-complication group (403 cases) were 33.2% and 50.9%, respectively (P=0.001). Multivariate analysis showed that age (HR=1.906, 95% CI: 1.248-2.913, P=0.003), ypTNM II to III stage (II stage: HR=5.853, 95% CI: 1.778-19.260, P=0.004; III stage: HR=10.800, 95% CI: 3.411-34.189, P<0.001), surgery time>3.5 h (HR=1.492, 95% CI: 1.095-2.033, P=0.011), total gastrectomy (HR=1.657, 95% CI: 1.216-2.257, P=0.001) and postoperative complications (HR=1.614, 95% CI: 1.125-2.315, P=0.009) were independent risk factors for prognosis, and postoperative adjuvant therapy (HR=0.578, 95% CI: 0.421-0.794, P=0.001) was an independent protective factor for prognosis. Conclusions: The occurrence of postoperative complications in gastric cancer patients undergoing neoadjuvant therapy is closely related to the age of the patients and the range of surgical resection. It is beneficial to improve the prognosis for these patients by paying more attention to the prevention of postoperative complications and the reinforcement of postoperative adjuvant therapy.

Abstract
For the spring-calving beef herds, late gestation coincides with winter and early spring, when cows are dependent on feed supplements with low quality hay, which is hard to meet their nutrient requirements. However, the effects of deficiencies of metabolizable protein intake during late gestation on offspring beef quality are unclear. Wagyu cattle have excellent marbling, and insemination with Wagyu vs Angus semen is a practical option for beef producers to improve beef quality. To test, Angus cows (621 ± 73 kg) were selected and randomly separated into two groups. Each group was inseminated with either Angus or Wagyu semen. During the last 90 days of gestation, cows in each group were further separated and received either a low protein diet (85% of the NRC metabolizable protein requirement), which was a low quality hay-based diet common in northwestern region of the U.S., or an adequate protein diet (108% NRC requirement). All progeny was managed together and harvested at a final BW of 576.5 ± 16.6 kg. Wagyu-sired offspring had higher marbling scores and quality grades than Angus (P < 0.01). Protein supplementation did not affect Slice Shear Force (SSF) in either breeds (P = 0.60). However, Wagyu-sired cattle had lower SSF than Angus-sired (P < 0.01). In addition, Wagyu-sired cattle had higher intramuscular fat (P < 0.05) and total collagen content (P < 0.05), but Angus-sired had greater mature collagen cross-links, as shown by higher contents of Pyridinoline (P < 0.01) and Ehrlich Chromogen (P < 0.01). Consistently, the mRNA expression of enzymes catalyzing collagen cross-linking was higher in Angus-sired offspring, including Plod 1 (P < 0.05), Plod 2 (P = 0.08), and P4Hα 2 (P < 0.01). In conclusion, Wagyu-sired cattle had greater tenderness and marbling score compared to Angus-sired, which was associated with lower collagen cross-links. Feeding mature grass hay-based diet with relatively low protein content during late gestation had no major effect on beef quality of subsequent cattle.

Abstract
Background: This study assessed the expression of Jagged2 in human bladder cancer (BC) tested the hypothesis that melatonin (Mel) inhibited the tumorigenesis of BC cells mainly through downregulating the Notch/Jagged2 and PI3K/AKT/mTOR/MMPs(2&9) signaling pathways. Methods and Results: Tissue array from BC patients showed that the gene and protein expressions of JAG2/Jagged2 were significantly upregulated from T1 to T3 (primary tumor size) and from stage I to III (all p<0.001). In vitro study showed that in BC cell line of UMUC3, the cellular and protein expressions of Jagged2 were significantly attenuated in Mel-treated UMUC3 and further attenuated in UMUC3 shRNA silenced Notch/JAG2 (UMUC3KD) than in UMUC3 only (all p<0.0001). The protein expressions of Notch/Jagged2/MMPs(2&9)/PI3K/p-AKT/mTOR/p53/ratio of LC3BII/LC3B-I were significantly progressively reduced from UMUC3 to UMUC3+Mel/1.0mM, further to UMUC3+Mel/2.0mM and furthermore to UMUC3KD (all p<0.0001). The cell proliferation/invasion/colony formation/healing-process were significantly inhibited in Mel-treated/2.0mM UMUC3 and further significantly inhibited in UMUC3KD regardless of Mel treatment as compared with UMUC3 only (all p<0.0001). By day 28 after UMUC3 implanted into nude mouse back, the BC weight/volume were significantly reduced in UMUC3+Mel (100 mg/kg/day) and furthermore reduced in UMUC3KD (all p<0.0001) as compared with UMUC3 only (all p<0.0001). The cellular (MMPs(2&9)/Notch/Jagged2) and protein (Notch/Jagged2/PI3K/p-AKT/mTOR/MMPs(2&9)) exhibited a similar trend, whereas the PTEN protein level exhibited an opposite pattern of PI3K among three groups (all p<0.0001). Conclusion: Notch/Jagged-PI3K/p-AKT/mTOR/MMPs is one essential signaling pathway for BC survival, proliferation and invasion that were remarkably suppressed by Mel treatment.

Abstract
BACKGROUND This study tested the hypothesis that combined hyperbaric oxygen (HBO) and autologous adipose-derived mesenchymal stem cell (ADMSC) therapy was superior to either alone at protecting renal function in rodents after acute ischemia-reperfusion (IR) injury. METHODS AND RESULTS Adult-male SD rats (n = 40) were equally categorized: group 1 (sham-operated control); group 2 (IR + 50 μg medium intra-renal artery administration); group 3 [IR + HBO (at 1.5 h and days 1 and 2 after IR)]; group 4 [IR + ADMSC (2.0×106 cells/5.0×105/per each renal artery and 1.0×106 by intravenous injection at 1.5 h after IR]; and group 5 (IR + HBO-ADMSC). By 72 hr after IR, the circulating levels of BUN/creatinine and ratio of urine protein/creatinine were significantly highest in group 2, lowest in group 1, significantly increased in group 5 than in groups 3 and 4, but not different between latter two groups, whereas the circulating levels of EPCs and soluble-angiogenesis biomarkers (SDF-1α/HIF-1α) exhibited an opposite pattern to BUN/creatinine among the five groups (all P<0.001). The kidney injury score, ROS (fluorescent intensity of H2DCFDA dye in kidney), inflammation (F4/80+, CD14+ cells) and glomerular-tubular injury score (WT-1/KIM-1) displayed an identical pattern whereas the integrity of podocyte components exhibited an opposite pattern to BUN/creatinine among the five groups (all P<0.0001). The protein expressions of inflammatory (MMP-9/TNF-α/NF-κB/ICAM-1), oxidative-stress (NOX-1/NOx-2/oxidized protein) and apoptotic (mitochondrial-Bax/cleaved-caspase3/PARP) markers showed an identical pattern to BUN/creatinine (all P<0.001). CONCLUSION Combined ADMSC-HBO therapy was superior to either one alone at protecting the kidney from acute IR injury.

Abstract
BACKGROUND Body composition metrics as predictors of adverse events are a growing area of interest in oncology research. One barrier to the use of these metrics in clinical practice is the lack of standardized cut points for identifying patients with at-risk body composition profiles. We examined the association of chemotherapy adverse events with several body composition measures, using alternative cut points from published studies. METHODS This is a retrospective study of women diagnosed with early breast cancer (EBC). Axial computerized tomography (CT) images from lumbar L3 segments were analyzed for the following body composition measures: myosteatosis (low Skeletal Muscle Density/SMD), sarcopenia (low Skeletal Muscle Index/SMI), and high Visceral Adipose Tissue (VAT). Adverse events during chemotherapy were dose reduction, early treatment discontinuation, and hospitalization. Log-binomial modeling was used to evaluate associations between body composition measures at different cut points with adverse events, adjusting for age, race, Body Mass Index/BMI, and comorbidities. Relative risks were reported as the measure of association. RESULTS In a sample of 338 women, mean age was 51, 14% were age 65 or older, 32% were non-white, 40% had obesity (/BMI ≥ 30 kg/m2), and mean number of comorbidities was 1.56. In multivariable analysis (MV), all three SMD cut points for myosteatosis had significant associations with total number of adverse events, as well as different cut points having significant associations with either dose reduction, early treatment discontinuation or hospitalization. SMI and VAT were not significant in the MV analysis; however, in some models, age and total comorbidities were significant for adverse events. CONCLUSIONS Among CT-derived measures of body composition, myosteatosis determined at any of three SMD cut points was associated with total and individual adverse events during chemotherapy for early breast cancer.

Abstract
Galectin-1 (GAL1) is a β-galactoside-binding protein involved in multiple aspects of tumorigenesis. However, the biological role of GAL1 in upper tract urothelial carcinoma (UTUC) has not been entirely understood. Herein, we investigated the oncological effects of GAL1 expression in tumor specimens and identified related gene alterations through molecular analysis of GAL1. Clinical parameter data and tumor specimens were collected from 86 patients with pT3N0M0 UTUC who had undergone radical nephroureterectomy. We analyzed the difference in survival by using Kaplan-Meier analyses and Cox proportional regression models and in GAL1 expression by using immunohistochemical (IHC) methods. Public genomic data from the Cancer Genome Atlas (TCGA) and GSE32894 data sets were analyzed for comparison. Using four urothelial carcinoma (UC) cell lines (BFTC-909, T24, RT4, and J82) as in vitro models, we evaluated the functions of GAL1 in UC cell growth, invasiveness, and migration and its role in downstream signaling pathways. The study population was classified into two groups, GAL1-high (n = 35) and GAL1-low (GAL1 n = 51), according to IHC interpretation. Univariate analysis revealed that high GAL1 expression was significantly associated with poor recurrence-free survival (RFS; p = 0.028) and low cancer-specific survival (CSS; p = 0.025). Multivariate analysis revealed that GAL1-high was an independent predictive factor for RFS (hazard ratio (HR) 2.43; 95% confidence interval (CI) 1.17-5.05, p = 0.018) and CSS (HR 4.04; 95% CI 1.25-13.03, p = 0.019). In vitro studies revealed that GAL1 knockdown significantly reduced migration and invasiveness in UTUC (BFTC-909) and bladder cancer cells (T24). GAL1 knockdown significantly reduced protein levels of matrix metalloproteinase-2 (MMP-2) and MMP-9, which increased tissue inhibitor of metalloproteinase-1 (TIMP-1) and promoted epithelial-mesenchymal transition (EMT). Through gene expression microarray analysis of GAL1 vector and GAL1-KD cells, we identified multiple significant signaling pathways including p53, Forkhead box O (FOXO), and phosphoinositide 3-kinase/protein kinase B (PI3K/AKT). We validated microarray results through immunoblotting, thus proving that downregulation of GAL1 reduced focal adhesion kinase (FAK), p-PI3K, p-AKT, and p-mTOR expression. We concluded that GAL1 expression was highly related to oncological survival in patients with locally advanced UTUC. GAL1 promoted UC invasion and metastasis by activating the FAK/PI3K/AKT/mTOR pathway.

Abstract
BACKGROUND The efficacy of topical rapamycin is well documented for tuberous sclerosis complex (TSC)-related facial angiofibromas (FAs). Calcitriol has been shown to lessen skin fibrosis and may be therapeutically beneficial to FAs. OBJECTIVES To evaluate whether topical rapamycin-calcitriol combination is an effective and safe treatment for TSC-related FAs. METHODS Fifty-two patients with TSC with FAs were enrolled in this prospective study including three 12-week periods. In period 1, either topical rapamycin 0·1% or calcitriol 0·0003% single-agent therapy vs. their combination was applied in a double-blind, left-right-randomized, split-face comparison. The primary outcome was the reduction of modified Facial Angiofibroma Severity Index (mFASI) at week 12. In period 2, the patients were reassigned to use on both cheeks the ointment that resulted in the better primary outcome in period 1. The treatment was discontinued in period 3 (week 25-36) and a follow-up mFASI was scored to evaluate the degree of recurrence. RESULTS The mean changes in mFASI at week 12 compared with baseline were -0·92, -0·44 and -1·09 for rapamycin (P ≤ 0·001), calcitriol (P = 0·039) and rapamycin-calcitriol combination (P ≤ 0·001), respectively. Although rapamycin-calcitriol combination and rapamycin had similar statistically significant decreases of mFASI at week 12, rapamycin-calcitriol combination resulted in faster improvement in erythema, greater reduction of papule elevation and longer durability after discontinuing treatment than rapamycin alone. The treatments were well tolerated. CONCLUSIONS This randomized clinical trial demonstrates that topical rapamycin-calcitriol combination therapy is an effective and safe regimen for TSC-related FAs. What is already known about this topic? Facial angiofibromas (FAs) cause substantial psychological distress in individuals with tuberous sclerosis complex (TSC), but invasive procedural treatments are not applicable to all patients. Topical rapamycin has been demonstrated as an effective and safe treatment regimen for TSC-related FAs. What does this study add? Compared with baseline (day 0), both topical rapamycin 0·1% and rapamycin 0·1%-calcitriol 0·0003% combination ointment achieved statistically significant reductions in modified Facial Angiofibroma Severity Index at week 12. Compared with rapamycin alone, extended use of the rapamycin-calcitriol combination regimen until week 24 showed more effectiveness in decreasing papule elevation and could maintain a longer therapeutic effect after treatment discontinuation.

Abstract
BACKGROUND This study tested the long-term effect of extracorporeal shock wave (ECSW) therapy on ameliorating radiotherapy-induced chronic cystitis (CC) in rat. METHODS AND RESULTS Adult-female SD rats (n = 24) were equally categorized into group 1 (normal control), group 2 (CC induced by radiotherapy with 450 cGy twice with a four-hour interval to the urinary bladder), group 3 [CC with ECSW treatment (0.1 mJ/mm2/120 impulses once every 3 days after radiotherapy)]. Bladder specimens were harvested by day 60 after radiotherapy. By day 60, the degree of detrusor contraction was significantly reduced in group 2 than groups 1 and 3, and significantly reduced in group 3 than in group 1 (P < 0.0001). Number of WBC, occulted blood and bacteria were significantly higher in group 2 than in groups 1 and 3 (P < 0.01), but they showed no difference between the latter two groups (P > 0.3). The protein expressions of oxidative stress (NOX-1/NOX-2/oxidized protein), apoptosis (cleaved-caspase-3/cleaved-PARP), DNA-damaged marker (γ-H2AX), fibrosis (TGF-β/Smad3) and inflammatory signaling (TLR-4/MYD88/Mal/TRAF6/p-IκBα/p-NFκB/TNF-α/MMP-9/COX-2) were significantly higher in group 2 than in group 1, and were significantly reduced in group 3 (all P < 0.001). The cellular expressions of inflammatory (CD14+/CD68+/MIF+/MMP-9), immunoreactive (CD4+/CD8+) and cytokeratin (CK17/CK18) biomarkers, and collagen-deposition/fibrotic areas as well as bladder-damaged score/disruption of the bladder mucosa displayed an identical pattern compared to that of oxidative stress among the three groups (all P < 0.0001). CONCLUSION The long-term effect of ECSW treatment was reliable on protecting the urinary bladder from radiation-induced CC.

Abstract
Objective: To investigate the therapeutic strategy in patients with early gastric cancer after noncurative endoscopic submucosal dissection (ESD). Methods: A total of 107 cases with early gastric cancer receiving noncurative endoscopic submucosal dissection were collected and the patients were classified into an additional gastrectomy group (n=41) and a simple follow-up group (n=66) according to the therapeutic method used after noncurative ESD. The clinicopathological information, short- and long-term clinical outcomes between the two groups were analyzed and compared. Results: The mean age of the patients in the gastrectomy group and follow-up group was(59.2±8.7)years old and(64.7±8.8)years old, respectively. The depth of submucosal invasion was (1445.83±803.12) and (794.71±815.79) μm, respectively. The difference between the two groups was statistically significant (P=0.020 for age and P=0.010 for depth of submucosal invasion). Compared with follow-up group, the patients with undifferentiated histologic type, deep invasion of submucosa (SM2), diffuse type, lymphovascular invasion and neural invasion were more common in the gastrectomy group (P<0.05). The R0 resection rate of ESD in the gastrectomy group was significantly lower than the follow-up group(26.8% vs 65.2%, P<0.001). The positive residual tumor rate and LNM rate of additional gastrectomy group were 31.7%(13/41)and 9.76%(4/41)according to the pathological results after gastrectomy. The gastrectomy group had 2 cases of local recurrence (2/41, 4.9%), while 5(5/66, 7.6%)in the follow-up group(4.9% vs 7.6%, P=0.883). There was no significant difference in overall survival (OS) and disease-free survival (DFS) between the two study groups (P=0.066 and 0.938, respectively). Conclusions: Assessment of LNM risk should be performed in patients with noncurative endoscopic resection. For patients with low risk of LNM who are intolerance of additional gastrectomy due to old age and comorbidities, close follow-up with endoscopy can be considered as an alternative.

Abstract
This study tested the hypothesis that preactivated and disaggregated shape-changed platelet (PreD-SCP) therapy significantly protected rat kidney from ischemia-reperfusion (IR) injury. Adult-male Sprague-Dawley rats (n = 24) were equally categorized into Groups 1 (sham-operated control [SC]), 2 (SC + PreD-SCP), 3 (IR only), and 4 (IR + PreD-SCP). By 72 hr after IR procedure, the circulatory levels of creatinine, blood urine nitrogen and inflammatory biomarkers (interleukin [IL]-6/tumor necrosis factor [TNF]-α), and ratio of urine protein to urine creatinine were significantly higher in Group 3 than in other groups and significantly higher in Group 4 than in Groups 1 and 2, but they showed no different between Groups 1 and 2 (all p < .001). The microscopic findings showed that the expressions of kidney injury score, cellular inflammation (MMP-9/CD14//F4/80), and fibrotic area were identical to the circulatory inflammation, whereas the integrity of podocyte components (ZO-1/synaptopodin/podocin) exhibited an opposite to circulatory inflammation among the four groups (all p < .0001). The protein expressions of inflammatory (TNF-α/IL-1ß/NF-κB/iNOS/TRAF6/MyD88/TLR-4), apoptotic/cell death (mitochondrial Bax/cleaved caspase-3/p-53), oxidized protein, mitogen-activated protein kinase family (p-38/p-JNK/p-c-JUN), and mitochondrial-damaged biomarkers displayed a similar pattern, whereas the antiapoptotic (Bcl-2/Bcl-XL) and integrity of mitochondrial biomarkers followed an opposite trend to circulatory inflammation among the four groups (all p < .001). PreD-SCP therapy effectively protected the kidney against IR injury.

Abstract
BACKGROUND This study tested the hypothesis that Entresto could safely and effectively preserve heart and kidney function in rats with cardiorenal syndrome (CRS) induced by 5/6 nephrectomy and intra-peritoneal doxorubicin administration (accumulated dosage up to 7.5 mg/kg) together with daily high-protein-diet (HPD). METHODS AND RESULTS Adult male Sprague-Dawley rats (n = 24) were equally categorized into Group 1 (sham-operated control + HPD), Group 2 (CRS + HPD) and Group 3 [CRS + HPD + Entresto (100 mg/kg/day orally) since Day 14 after CRS induction] and euthanized by Day 63 after CRS induction. By Day 63, circulatory BUN and creatinine levels and ratios of urine protein to creatinine were significantly higher in Group 2 than those in Groups 1 and 3, and significantly higher in Group 3 than in Group 1, whereas left-ventricular ejection fraction and kidney weight showed an opposite pattern among all groups (all p < 0.001). Microscopically, fibrosis area and intensity of oxidative stress (i.e., DCFDA stain) in kidney/heart tissues exhibited a pattern identical to that of creatinine level among all groups (all p < 0.0001). Kidney injury score and protein expressions of autophagy (i.e., beclin-1/Atg-5/protein ratio of LC3-BII/LC3-BI), fibrosis (Smad3/TGF-ß), apoptosis (mitochondrial-Bax/capase2/3/9), oxidative-stress (NOX-4/oxidized protein/xanthine-oxidase/catalase), membranous p47phox phosphorylation and mitochondrial-damage biomarker (cytosolic-cytochrome-C) were higher in Group 2 than those in Groups 1 and 3, and significantly higher in Group 3 than in Group 1, while protein expressions of anti-apoptosis (Bcl-2/Bcl-XL) and mitochondrial integrity (mitochondrial-cytochrome-C) markers displayed an opposite pattern among all groups in kidney tissues (all p < 0.0001). CONCLUSION Oral administration of entresto was safe and could offer protection against CRS-induced heart and kidney damage.

Abstract
BACKGROUND The Hemiptera (aphids, cicadas, and true bugs) are a key insect order, with high diversity for feeding ecology and excellent experimental tractability for molecular genetics. Building upon recent sequencing of hemipteran pests such as phloem-feeding aphids and blood-feeding bed bugs, we present the genome sequence and comparative analyses centered on the milkweed bug Oncopeltus fasciatus, a seed feeder of the family Lygaeidae. RESULTS The 926-Mb Oncopeltus genome is well represented by the current assembly and official gene set. We use our genomic and RNA-seq data not only to characterize the protein-coding gene repertoire and perform isoform-specific RNAi, but also to elucidate patterns of molecular evolution and physiology. We find ongoing, lineage-specific expansion and diversification of repressive C2H2 zinc finger proteins. The discovery of intron gain and turnover specific to the Hemiptera also prompted the evaluation of lineage and genome size as predictors of gene structure evolution. Furthermore, we identify enzymatic gains and losses that correlate with feeding biology, particularly for reductions associated with derived, fluid nutrition feeding. CONCLUSIONS With the milkweed bug, we now have a critical mass of sequenced species for a hemimetabolous insect order and close outgroup to the Holometabola, substantially improving the diversity of insect genomics. We thereby define commonalities among the Hemiptera and delve into how hemipteran genomes reflect distinct feeding ecologies. Given Oncopeltus's strength as an experimental model, these new sequence resources bolster the foundation for molecular research and highlight technical considerations for the analysis of medium-sized invertebrate genomes.

Abstract
BACKGROUND The Hemiptera (aphids, cicadas, and true bugs) are a key insect order, with high diversity for feeding ecology and excellent experimental tractability for molecular genetics. Building upon recent sequencing of hemipteran pests such as phloem-feeding aphids and blood-feeding bed bugs, we present the genome sequence and comparative analyses centered on the milkweed bug Oncopeltus fasciatus, a seed feeder of the family Lygaeidae. RESULTS The 926-Mb Oncopeltus genome is well represented by the current assembly and official gene set. We use our genomic and RNA-seq data not only to characterize the protein-coding gene repertoire and perform isoform-specific RNAi, but also to elucidate patterns of molecular evolution and physiology. We find ongoing, lineage-specific expansion and diversification of repressive C2H2 zinc finger proteins. The discovery of intron gain and turnover specific to the Hemiptera also prompted the evaluation of lineage and genome size as predictors of gene structure evolution. Furthermore, we identify enzymatic gains and losses that correlate with feeding biology, particularly for reductions associated with derived, fluid nutrition feeding. CONCLUSIONS With the milkweed bug, we now have a critical mass of sequenced species for a hemimetabolous insect order and close outgroup to the Holometabola, substantially improving the diversity of insect genomics. We thereby define commonalities among the Hemiptera and delve into how hemipteran genomes reflect distinct feeding ecologies. Given Oncopeltus's strength as an experimental model, these new sequence resources bolster the foundation for molecular research and highlight technical considerations for the analysis of medium-sized invertebrate genomes.

Abstract
Objective: To assess the safety, feasibility and short-term outcome of totally laparoscopic distal gastrectomy(TLDG). Methods: Seventy-five patients who underwent laparoscopic distal gastrectomy in Cancer Hospital of Chinese Academy of Medical Science between August 2015 and April 2018 were enrolled in this study. A total of 46 laparoscopy-assisted distal gastrectomy (LADG) cases and 29 TLDG cases were included. The Short-term outcomes and safeties of the two groups were compared. Results: The operation time of TLDG group was significantly longer than that of LADG group (207±41 vs. 156±34 min, P<0.001), while the length of wound was shorter in the TLDG group (3.6±0.6 vs. 5.8±0.8 cm, P<0.001). The time to first flatus in TLDG group was (3.3±0.6) days, significantly shorter than (3.7±0.8) days in LADG group (P=0.034). There were no significant differences between the two groups in the estimated blood loss, intraoperative blood transfusion, extraction of gastric tube, drainage tube removal, interval of the first time to eat semi-liquid food, postoperative hospital stays, surgical complications, number of retrieved lymph nodes, proximal and distal resection margin lengths (all P>0.05). The white blood cell count at postoperative day 1 in the TLDG group was (10.96±1.96) ×10(9)/L, significantly lower than (12.49±3.46)×10(9)/L of the LADG group (P=0.017). While the CRP level at postoperative day 1 in the TLDG group were lower than that of LADG group, no statistical difference was observed (P=0.072). Conclusions: Our study shows that TLDG is safe and feasible. TLDG has better cosmesis, less blood loss, and faster recovery compared to LADG.

Abstract
Introduction: Our hospital is a tertiary medical center located in southern Taiwan, which is an endemic area for upper tract urothelial carcinoma (UTUC) cases. Using a large registry-based surgical database, we examined our cohort of patients with UTUC, and evaluated the treatment outcome and gender-specific differences in this population. Methods: A total of 506 patients with localized UTUC undergoing nephroureterectomy from 2004 to 2013 were enrolled. The patient, tumor, and treatment-related characteristics were prospectively recorded by the registry. Overall (OS) and cancer-specific (CSS) survival outcomes were evaluated as well. Gender differences as related to clinical and pathological factors were examined by chi-square testing. Univariate and multivariate Cox regression analyses were applied. Results: There were more female patients (57.9%) in this population. The median follow-up was 6.9 years for living patients. The actuarial 5-year OS and CSS rates were 69.4 and 84.9%, respectively. Being female, aged <70 years, and early T-stage were statistically significantly associated with better OS and CSS by multivariate analyses. The 5-year CSS rates for females vs. males were 89.6 and 78.5%, respectively (P < 0.005). A subgroup analysis suggested that better survival outcomes for females only existed in the stage 0a/0is/I (non-muscle-invasive), but not in the advanced stage. Conclusions: In an endemic area, females were more likely diagnosed with UTUC, but had significantly improved OS and CSS compared to their male counterparts, which were mostly driven by the non-muscle-invasive cases. Future research should focus on better understanding the epidemiologic risk-factor profile and pathophysiologic differences based on gender.

Abstract
There still lacking effective treatment for bladder cancer. This study investigated whether melatonin (Mel) can suppress the growth and invasion of bladder cancer cells. Male C57B/L6 mice were categorized into control group (ie, subcutaneous injection of HT1197 bladder cancer cell line at the back] and treatment group [subcutaneous HT1197 cells + intraperitoneal Mel (100 mg/kg/d) from day 8 to day 21 after tumor cell injection]. In vitro Mel suppressed cell growth of four bladder cancer cell lines (ie, T24, RT4, HT1197, HT1376), cell migration in HT1197/HT1376, mitochondrial membrane potential (MMP) in T24 and colony formation in RT4 cells as well as arrested the cell cycle at G0 phase and inhibited the mitotic phase of T24 cells (all P < 0.0001). Protein expression of ZNF746 in RT4/T24 cells and protein expression phosphorylated (p)-AKT/MMP-2/MMP-9 in HT1197/HT1376 cells were reduced following Mel treatment (all P < 0.001). Transfection of T24 cells with plasmid-based shRNA (ie, ZNF746-silencing) downregulated the protein expression of MMP-9, cell growth, and invasion and attachment to endothelial cells but upregulated the colony formation (all P < 0.001). Mel suppressed oxidative stress and MMP but upregulated mitochondria mass in ZNF746-silenced T24 cells, whereas these parameters exhibited a similar patter to Mel treatment in ZNF746-silenced T24 cells (all P < 0.0001). In vivo study demonstrated that Mel treatment significantly suppressed cellular expressions of MMP-9/MMP-2, protein expressions of ZNF746/p-AKT, and tumor size (all P < 0.001). Mel treatment suppressed the growth, migration, and invasion of bladder carcinoma cells through downregulating ZNF746-regulated MMP-9/MMP-2 signaling.

Abstract
BACKGROUND We tested the hypothesis that extracorporeal shockwave treatment (ESWT) can abolish inflammation and restore urothelial barrier integrity in acute interstitial cystitis by upregulating the fatty acid receptor GPR120. METHODS A total of 30 female Sprague-Dawley rats were categorized into five groups: (1) sham-operated rats (SC); (2) rats treated with ESWT (SC + ESWT); (3) rats with bladder irritation using 150 mg/kg cyclophosphamide through intraperitoneal injection; (4) cyclophosphamide rats treated with ESWT (cyclophosphamide+ESWT); (5) cyclophosphamide rats treated with GPR120 agonist (cyclophosphamide+GW9508). RESULTS On Day 3, urine and bladder specimens were collected for biochemical, histopathological, immunological, and immunoblotting analysis. Following stimulation with cyclophosphamide, the inhibition of the elevated levels of TAK1/NF-κB and phospho-TAK1/NF-κB by ESWT and GPR120 agonists in RT4 cells was associated with a suppression of NF-κB translocation from the cytosol to the nucleus. Accordingly, this anti-inflammatory effect was abolished by GPR120 antagonist and knockdown of GPR120. Histologically, bladder inflammation in cyclophosphamide-treated rats was suppressed by GW9508 or ESWT. Masson's trichrome and Sirius red staining revealed that cyclophosphamide treatment enhanced synthesis of extracellular matrix in rats that was reversed by GW9508 or ESWT. Upregulated pro-inflammatory mediators and cytokines in the cyclophosphamide-treated rats were also suppressed in the GW9508- or ESWT-treated rats. The significantly increased inflammatory cell infiltration as well as the impaired urothelial integrity of the bladder after cyclophosphamide treatment were reversed by treatment with GW9508 or ESWT. CONCLUSIONS These findings suggest that GPR120, the sensing receptor for ESWT, may be useful in the treatment of interstitial cystitis by inhibiting inflammatory response in bladder cells.

Abstract
This study tested whether inducible pluripotent stem cell (iPSC)-derived mesenchymal stem cell (MSC) therapy could effectively protect kidney from acute ischemia (1 h) - reperfusion (5 day) injury (IRI). Male-adult SD-rats (n = 24) were equally categorized into groups 1 (sham-control), 2 [sham-control + iPSC-MSC (1.2 × 106 cells/rat)], 3 (IR only) and 4 (IR + iPSC-MSC). Blood urine nitrogen/creatinine levels and ratio of urine protein to creatinine, kidney weight and expressions of inflammation (TNF-α/NF-κB), oxidative-stress (NOX-1/NOX-2/oxidized protein) and apoptosis (mitochondrial-Bax/cleaved caspase-3/PARP) were significantly higher in group 3 than in groups 1, 2 and 4 and significantly higher in group 4 than in groups 1 and 2 (all P<0.0001), but showed no differences between groups 1 and 2, whereas the protein expressions of anti-inflammation (IL-4/IL-10) and endothelial (CD31/vWF) markers exhibited an opposite pattern to inflammation among the four groups (all P<0.0001). Protein expressions of angiogenesis (VEGF/CXCR4/SDF-1α) markers progressively increased from groups 1 to 4 (all P<0.0001). Cellular expressions of kidney injury score/DNA-damage (γ-H2AX)/apoptotic nuclei and glomerulus-tubular-damage (KIM/FSP-1) displayed an identical pattern to inflammation, whereas the cellular expressions of glomerulus-tubular-integrity (dystroglycan/podocin/p-cadherin/synaptopodin/ZO-1/fibronectin) revealed an opposite pattern to inflammation among the four groups (all P<0.0001). In conclusion, iPSC-derived MSC therapy effectively protected kidney against IRI.

Abstract
This study tested the hypothesis that extracorporeal shock wave (ECSW) treatment can effectively inhibit radiation-induced chronic cystitis (CC). Adult male Sprague-Dawley (SD) rats (n = 24) were randomly divided into group 1 (normal control), group 2 (CC induced by radiation with 300 cGy twice with a four-hour interval to the urinary bladder), group 3 [CC with ECSW treatment (0.2 mJ/mm2/120 impulses/at days 1, 7, and 14 after radiation)]. Bladder specimens were harvested by day 28 after radiation. By day 28 after radiation, the degree of detrusor contraction impairment was significantly higher in group 2 than that in groups 1 and 3, and significantly higher in group 3 than that in group 1 (P<0.0001). The urine albumin concentration expressed an opposite pattern compared to that of detrusor function among the three groups (P<0.0001). The bladder protein expressions of inflammatory (TLR-2/TLR-4/IL-6/IL-12/MMP-9/TNF-α/NF-κB/RANTES/iNOS) and oxidative-stress (NOX-1/NOX-2/oxidized protein) biomarkers exhibited a pattern identical to that of urine albumin in all groups (all P<0.0001). The cellular expressions of inflammatory (CD14+/CD68+/CD74+/COX-2/MIF+/substance P+) and cytokeratin (CK13+/HMW CK+/CK+17/CK+18/CK+19) biomarkers, and collagen-deposition/fibrotic areas as well as epithelial-damaged score displayed an identical pattern compared to that of urine albumin among the three groups (all P<0.0001). In conclusion, ECSW treatment effectively protected urinary bladder from radiation-induced CC.

Abstract
OBJECTIVES Kidney transplantation (KT) is an important renal replacement therapy for end-stage renal disease (ESRD). The incidence of upper urinary tract urothelial carcinoma (UTUC) is relatively higher in Taiwan. According to our institutional database, early onset of post-KT UTUC is not uncommon. Early detection of post-KT UTUC is an important issue to improve oncologic outcome. Because painless hematuria is a common symptom for UTUC, this study analyzes whether using hematuria as post-KT UTUC screening delayed cancer diagnosis or not. METHODS From 2005 to 2012, 128 ESRD patients were found to have UTUCs. There were 28 patients who underwent KT and were regularly followed up at our institution. All the patients underwent standard nephroureterectomy. RESULTS In ESRD patients with UTUC, the post-KT group revealed significantly less gross hematuria and microscopic hematuria at presentation compared with the non-KT group (43% versus 76%, P = .001 and 64% versus 86%, P = .011). For those patients with gross hematuria, non-organ-confined UTUC occurred more in the post-KT group compared with the non-KT group (42% versus 12%, P = .009). For those patients with microscopic hematuria, non-organ-confined UTUC occurred more in the post-KT group compared with the non-KT group with borderline significance (33% versus 16%, P = .085). CONCLUSIONS According to our observation, using gross or microscopic hematuria as detection of post-KT UTUC is associated with delayed diagnosis of cancer occurrence. Closer upper urinary tract image study such as sonography may help earlier cancer screening.

Abstract
Microtubules, maintaining a non-linear structure, are suitable for direct observation in living mammalian by second-harmonic imaging microscopy (SHIM) (a new kind of confocal microscopies). Testes constituted by vast seminiferous microtubules (SM), serve as good candidates for visualization by SHIM. This study employs the SHIM and Western-blot (WB) to assess the cellular-molecular levels of doxorubicin (Dox)-induced mouse testicular damage. The SHIM examination was able to clearly identify the integrity of normal architecture of the living mouse testis, namely, the anatomical features of SM, smooth muscle wall of SM, manchette microtubules, exoplasmic microtubules in Sertoli cells and interstitial connective tissue, as well as the destructive feature of SM in Dox-treated mice (n = 6 per group). By day 21 after Dox-treatment, the testicular weight and testicular length were significantly progressively decreased as Dox dosage was stepwise increased, i.e., 0/5/10/15/20 mg/kg/body-weight (BW) (all p<0.0001). The cross-section area of SM was significantly lower in Dox-treated (15 mg/kg-BW) mice than that in controls (p<0.001). The protein expression of vimentin was significantly progressively increased whereas the protein expression of β-tubulin/androgen-receptor was significantly progressively decreased in stepwise increased Dox dosage (all p<0.001). The protein expressions of inflammatory (MMP-9/IL-1β/TNF-α/iNOX), oxidative-stress (NOX-1/NOX-2/NOX-4/oxidized protein), apoptotic (mitochondrial-Bax/cleaved-caspase-3/PARP), fibrotic (Smad3/TGF-ß) mitochondrial/DNA-damaged (cytosolic cytochrome-C/γ-H2AX/ATM/KU70), and cell apoptotic/death (PTEN/p53) biomarkers were significantly higher in Dox-treated (15 mg/kg-BW) group than those in controls (all p<0.001). In conlusion, the dose-dependent Dox-caused mouse testicular damage can be not only detected by WB in molecular level but also clearly identified by SHIM in living mice.

Abstract
This study tested the hypothesis that exendin-4 (Ex4) protects kidneys against ischemia-reperfusion (IR) injury mainly through upregulation of nuclear-factor erythroid 2-related factor 2 (Nrf2) signaling and downregulation of oxidative stress. Male-adult Sprague-Dawley rats (n=24) were equally divided into group 1 (sham-operated control), group 2 [IR only, ischemia (1 h)/reperfusion (72 h)] and group 3 (IR-Ex4, 10 μg/kg at 30 min, 24 h, 48 h after IR procedure). The in vitro study demonstrated that the protein expressions of phosphorylated (p)-Akt and Nrf2 were significantly progressively increased at time points of 0/0.5/1/3 h and 0/0.5/1/3/6/12/24 h, respectively in NRK-52E cells co-cultured with Ex4 (20 nM) (all P<0.0001). Additionally, the protein expressions of NOX-1/NOX2 were significantly increased, whereas p-Akt was significantly decreased in NRK-52E cells co-cultured with P-cresol (200 μM) that were significantly reversed after Ex4 treatment (all P<0.0001). As compared with baseline, the creatinine level, left/right kidney weight and MCP-1-positively stained area in the kidney parenchyma were significantly increased at 24 h after the IR procedure and significantly progressively decreased after that (all P<0.0001). By 27 h after IR, creatinine level/MCP-1 + area was significantly higher in group 2 than in groups 1 and 3, and significantly higher in group 3 than in group 1 (all P<0.0001). The numbers of Nrf2 +/NQO-1 + cells/SOD activity in kidney parenchyma were significantly lower in group 2 than in groups 1 and 3, and significantly lower in group 1 than in group 3 (all P<0.0001). In conclusion, Ex4 protected kidney from IR injury through upregulating antioxidants and downregulating inflammation/oxidative stress.

Abstract
The aim of this study was to develop a task set based on personalized material for nostalgic experience, which could detect cognitive ability via a virtual experience system combined with Kinect somatosensory interactive operation applications without the user wearing any accessory input device. Fifty-nine subjects participated in the experiment. The receiver operating characteristic curve of the game system was statistically analyzed for determining the best cutoff-point in the cognitive function assessment. Correlation analysis and regression analysis were used to explore the correlations between the results and the clinical cognitive assessment scales. According to the MoCA scores, the results showed that the accuracy of the system was 86.4% in evaluating mild cognitive impairment. The system seems feasible and was strongly correlated with clinical cognitive assessment scales. We anticipate that daily use of our system could keep track of changes of cognitive function of the elderly in home life.

Abstract
This study tested the hypothesis that combined therapy with exendin-4 (Ex4) and autologous adipose-derived mesenchymal stem cells (ADMSCs) was superior to either alone for protecting renal function against acute kidney ischemia-reperfusion (IR; 40-min ischemia/27-h reperfusion) injury when complicated by sepsis syndrome (SS; by cecal-ligation-puncture). Adult-male Sprague-Dawley rats (n=40) were equally divided into group 1 (sham-control), group 2 (IR-SS), group 3 (IR-SS + Ex4, 10 μg/kg subcutaneously 30 min after reperfusion and daily for 3 days), group 4 [IR-SS + ADMSC (1.2 × 106)], and group 5 (IR-SS + Ex4 + ADMSC). The circulating levels of BUN and creatinine and the ratio of urine protein to creatinine were highest in group 2, lowest in group 1, significantly higher in groups 3 and 4 than group 5, and significantly higher in group 3 than in group 4 (all P<0.0001). Microscopic findings of kidney injury score, inflammatory cells (CD14+, F4/80+), and expressions of glomerular-damage indicators (FSP-1+/WT-1+) and renal tubular-damage indicators (KIM-1+/snail+) showed an identical pattern, whereas expressions of indices of glomerular-integrity (ZO-1+/p-cadherin+/podocin+/synaptopodin+) and angiogenesis (CD31+/vWF+/number of small vessels) biomarkers demonstrated an opposite pattern, to that of creatinine level (all P<0.001). Protein expressions of inflammatory (MMP-9/IL-1ß/TNF-α/TLR-2/TLR-4), apoptotic (cleaved caspase-3/PARP/mitochondrial Bax), and oxidative-stress (NOX-1/NOX-2/oxidized protein) biomarkers exhibited an identical pattern, whereas anti-inflammatory (IL-10/IL-4) biomarkers displayed an opposite pattern, to that of creatinine level (all P<0.001). In conclusion, combined Ex4 and ADMSC therapy significantly protected kidney from acute IR-SS injury.

Abstract
Objective: Pancreatic neuroendocrine carcinoma (pNEC) is a highly malignant tumor.This study aimed to evaluate the role of surgery and the prognosis for patients with pancreatic neuroendocrine carcinoma (pNEC). Methods: We collected and reviewed all clinical data of patients who underwent radical surgery for pNEC from Jan 2000 through Jan 2016 in our hospital. Cox-regression analysis wasused to evaluate the factors potentially influencing survival. Results: Twenty patients including 11 males and 9 females (median age, 62.5 years) were included in this study. All patients underwent radical surgery and 17 cases received postoperative platinum-based chemotherapy.The median follow-up time was 41 months (range, 1 to 127 months). The 1-, 3-, and 5-year survival rates of the patients were 66.7%, 51.5% and 28.1%, with a median survival time of 75.3 months.The multivariate analysis indicated that tumor size and Ki-67 index were of prognostic significance. Conclusions: Pancreatic neuroendocrine carcinomas are rare but increasing in incidence. Patients with localized nonmetastatic primary tumors seem to benefit from surgery. Early diagnosis and multimodality therapy are key points of an improved survival.

Abstract
We analyzed the effects of acute ischemia-reperfusion (KIR) injury on the status of kidney function and architecture in dipeptidyl peptidase4-difficient (DPP4D) rats and the effect of remote small bowel ischemia-reperfusion (BIR) preconditioning. DPP4-deficient (DPP4D) and normal Fischer344 (F344) rats were divided into 6 groups: (1) sham-F344, (2) sham-DPP4D, (3) KIR-F344 (4) KIR-DPP4D, (5) DPP4D-KIR-extendin-9-39 and (6) BIR-KIR-F344. Blood creatinine and urea nitrogen levels and the urinary protein-to-creatinine ratio was higher in KIR-F344 rats than BIR-KIR-F344 or KIR-DPP4D rats 72 h after acute KIR. Conversely, the circulating glucagon-like peptide 1 (GLP-1) levels were higher in BIR-KIR-F344 and KIR-DPP4D than KIR-F344 rats after acute KIR. KIR-F344 rats showed greater inflammation, oxidative stress, apoptosis, DNA damage and kidney injury than other rat groups. Damage to the kidney architecture in KIR-F344 rats was greater than in BIR-KIR-F344 or KIR-DPP4D rats. Expression of antioxidant proteins and GLP-1 receptor was higher in kidneys from KIR-DPP4D and BIR-KIR-F344 than KIR-F344 rats, which suggests better intrinsic responses. We therefore suggest that elevated circulating GLP-1 levels due to DPP4 deficiency and BIR preconditioning protect kidney function and architecture during acute IR injury.
