Abstract
Objective: To explore the related factors influencing the detection rate of mosaic embryo and the pregnancy outcomes of mosaic embryo transfer in preimplantation genetic testing for aneuploidy (PGT-A) based on next generation sequencing (NGS) technology. Methods: A retrospective study was performed to analyze the clinical data of patients in 745 PGT-A cycles from January 2019 to May 2023 at Chongqing Health Center for Women and Children, including 2 850 blastocysts. The biopsy cells were tested using NGS technology, and the embryos were divided into three groups based on the test results, namely euploid embryos, aneuploid embryos and mosaic embryos. The influence of population characteristics and laboratory-related parameters on the detection rate of mosaic embryo were analyzed, and the pregnancy outcomes of 98 mosaic embryo transfer cycles and 486 euploid embryo transfer cycles were compared during the same period, including clinical pregnancy rate and live birth rate. Results: Among the embryos tested (n=2 850), the number and proportion of euploid embryos, aneuploid embryos and mosaic embryos were 1 489 (52.2%, 1 489/2 850), 917 (32.2%, 917/2 850) and 444 (15.6%, 444/2 850), respectively. Among mosaic embryos, 245 (55.2%, 245/444) were segmental mosaic embryos, 118 (26.6%, 118/444) were whole-chromosome mosaic embryos, and 81 (18.2%, 81/444) were complex mosaic embryos. NGS technology was performed in 4 genetic testing institutions and the detection rate of mosaic embryo fluctuated from 13.5% to 27.0%. The distributions of female age, level of anti-Müllerian hormone, PGT-A indications, ovulation-inducing treatments, gonadotropin (Gn) dosage, Gn days, inner cell mass grade, trophectoderm cell grade, genetic testing institutions and developmental stage of blastocyst were significantly different among the three groups (all P<0.05). Multi-factor analysis showed that the trophectoderm cell grade and genetic testing institutions were significantly related to the detection rate of mosaic embryo; compared with the trophectoderm cell graded as A, the detection rate of mosaic embryo was significantly increased in the trophectoderm cell graded as B-(OR=1.59, 95%CI: 1.04-2.44, P=0.033); compared with genetic testing institution a, the detection rate of mosaic embryo was significantly higher (OR=2.89, 95%CI: 2.10-3.98, P<0.001) in the testing institution c. The clinical pregnancy rate and live birth rate with mosaic embryos transfer were significantly lower than those of euploid embryos transfer (clinical pregnancy rate: 51.0% vs 65.2%, P=0.008; live birth rate: 39.4% vs 53.2%, P=0.017). After adjustment for age, PGT-A indications, trophectoderm cell grade and days of embryo culture in vitro, the clinical pregnancy rate and live birth rate with mosaic embryos transfer were significantly lower than those of euploid embryos transfer (clinical pregnancy rate: OR=0.52, 95%CI: 0.32-0.83, P=0.007; live birth rate: OR=0.50, 95%CI: 0.31-0.83, P=0.007). Conclusions: The trophectoderm cell grade and genetic testing institutions are related to the detection rate of mosaic embryo. Compared with euploid embryos transfer, the clinical pregnancy rate and live birth rate with mosaic embryos transfer are significantly reduced. For infertile couple without euploid embryos, transplantable mosaic embryos could be recommended according to the mosaic ratio and mosaic type in genetic counseling to obtain the optimal pregnancy outcome.

Abstract
The ever-growing requirement for electrochemical energy storage has exacerbated the production of spent batteries, and the recycling of valuable battery components has recently received a remarkable attention. Among all battery components, copper foil is widely utilized as a current collector for stable zinc platting and stripping in zinc metal batteries (ZMBs) due to the perfect lattice matching of between metal copper and zinc, which is accompanied by the formation of multiple copper-zinc alloy components during the cycling process. Herein, a novel "two birds with one-stone" strategy through a one simple heat treatment step to revive the discarded copper foil in zinc metal battery is reported to further obtain a lithiophilic current collector (CuxZny-Cu) with multiple copper-zinc alloy components on the surface of the discarded copper foil. Such revived CuxZny-Cu current collector greatly reduces the lithium nucleation overpotential and realizes uniform lithium deposition and further inhibits lithium dendrites growth. The formed multiple CuxZny alloy phases on the surface of discarded copper foil exhibit a low Li nucleation overpotential of only 15 mV at 0.5 mA cm-2 for the first cycle. Moreover, such a CuxZny-Cu current collector could achieve stable cycle for 220 cycles at 0.5 mA cm-2 and 110 cycles at 1 mA cm-2 with a Li plating capacity of 1 mAh cm-2. Theoretical calculations indicate that, compared with pure Cu foil, the formed multiple alloy components of CuZn5, CuZn8, Cu0.61Zn0.39 and CuZn have low adsorption energy of -2.17, -2.55, -2.16 and -2.35 eV with lithium atoms, respectively, which result in reduced lithium nucleation overpotential. The full cell composed of CuxZny alloy current collector with deposition of 5 mAh cm-2 metal Li anode coupled with LiFePO4 (LFP) cathode exhibits a reversible capacity of 125.6 mAh/g after 110 cycles at a current of 0.5 C with capacity retention of 85.1 %. This work proposed a promising strategy to regenerate the discarded copper foil in rechargeable batteries.

Abstract
Osimertinib (Osi) is widely used as a first-line treatment for non-small cell lung cancer (NSCLC) with EGFR mutations. However, the majority of patients treated with Osi eventually relapse within a year. The mechanisms of Osi resistance remain largely unexplored, and efficient strategies to reverse the resistance are urgently needed. Here, we developed a lactoferrin-modified liposomal codelivery system for the combination therapy of Osi and panobinostat (Pan), an epigenetic regulator of histone acetylation. We demonstrated that the codelivery liposomes could efficiently repolarize tumor-associated macrophages (TAM) from the M2 to M1 phenotype and reverse the epithelial-mesenchymal transition (EMT)-associated drug resistance in the tumor cells, as well as suppress glycolysis, lactic acid production, and angiogenesis. Our results suggested that the combination therapy of Osi and Pan mediated by liposomal codelivery is a promising strategy for overcoming Osi resistance in NSCLC.

Abstract
Since 2002, a long-term field experiment has been conducted to determine the effects of different organic fertilization treatments on the bacterial community characteristics and maize productivity in dryland red soil using high-throughput sequencing technology. The experiment consisted of four treatments:no manure, M0; low manure, M1; high manure, M2; and high manure with lime addition, M3. Our results showed that the different organic fertilization treatments(M1, M2, and M3) significantly promoted maize productivity with the highest values of pH, soil organic matter(SOM), total nitrogen(TN), and total phosphorus(TP) compared to that under the M0 treatment, and the high manure with lime addition(M3) treatment had the highest level of maize production. The different organic fertilization treatments significantly increased the Shannon index, Evenness index, Chao1 index, and ACE index and significantly shaped the composition of the bacterial community. TP and pH were the main variables determining soil bacterial diversity index based on random forest modeling analysis, whereas pH, SOM, TP, and TN were the main variables determining the structure of the soil bacterial community. Correlation analysis and structural equation modeling determined that TP and SOM indirectly affected maize productivity by varying the bacterial diversity and community structure. The results of this study provide the scientific basis for ensuring food security and sustainable agricultural development by improving the fertility and bacterial diversity in dryland red soil.

Abstract
OBJECTIVE AND DESIGN Post-traumatic urethral stricture is a clinical challenge for both patients and clinicians. Targeting glutamine metabolism to suppress excessive activation of urethral fibroblasts (UFBs) is assumed to be a potent and attractive strategy for preventing urethral scarring and stricture. MATERIAL OR SUBJECTS In cellular experiments, we explored whether glutaminolysis meets the bioenergetic and biosynthetic demands of quiescent UFBs converted into myofibroblasts. At the same time, we examined the specific effects of M2-polarized macrophages on glutaminolysis and activation of UFBs, as well as the mechanism of intercellular signaling. In addition, findings were further verified in vivo in New Zealand rabbits. RESULTS It revealed that glutamine deprivation or knockdown of glutaminase 1 (GLS1) significantly inhibited UFB activation, proliferation, biosynthesis, and energy metabolism; however, these effects were rescued by cell-permeable dimethyl α-ketoglutarate. Moreover, we found that exosomal miR-381 derived from M2-polarized macrophages could be ingested by UFBs and inhibited GLS1-dependent glutaminolysis, thereby preventing excessive activation of UFBs. Mechanistically, miR-381 directly targets the 3'UTR of Yes-associated protein (YAP) mRNA to reduce its stability at the transcriptional level, ultimately downregulating expression of YAP, and GLS1. In vivo experiments revealed that treatment with either verteporfin or exosomes derived from M2-polarized macrophages significantly reduced urethral stricture in New Zealand rabbits after urethral trauma. CONCLUSION Collectively, this study demonstrates that exosomal miR-381 from M2-polarized macrophages reduces myofibroblast formation of UFBs and urethral scarring and stricture by inhibiting YAP/GLS1-dependent glutaminolysis.

Abstract
As a specific type of asthenoteratozoospermia, multiple morphological abnormalities of the sperm flagella (MMAF) is characterized by composite abnormalities, including absent, short, coiled, angulation, and irregular-caliber flagella. Mutations in cilia- and flagella-associated protein 43 ( CFAP43 ) are one of the main causative factors of MMAF established to date. To identify whether there are other CFAP43 mutations related to MMAF and to determine the clinical outcomes of assisted reproductive technology for patients with MMAF harboring different mutations, we recruited and screened 30 MMAF-affected Chinese men using a 22-gene next-generation sequencing panel. After systematic analysis, seven mutations in CFAP43 , including five novel mutations and two previously reported mutations, were identified from four families and related to MMAF in an autosomal recessive pattern. Papanicolaou staining, immunofluorescence, and electronic microscopy further clarified the semen characteristics and abnormal sperm morphologies, including disorganized axonemal and peri-axonemal structures, of the CFAP43 -deficient men. The female partners of two patients were pregnant after undergoing assisted reproductive technology through intracytoplasmic sperm injection, and one of them successfully gave birth to a healthy boy. This study significantly expands the mutant spectrum of CFAP43 , and together with the available information regarding male infertility and MMAF, provides new information for the genetic diagnosis and counseling of MMAF in the future.

Abstract
OBJECTIVE This study aimed to identify potential biomarkers for prostate cancer (PCa) progression and metastasis, and to discern their biological functions. METHODS Bioinformatics methods were used to screen for hub genes. The expression level of key hub genes in PCa was determined and their prognostic significance was examined. A series of functional assays were performed to investigate the function of the highest-ranking hub gene. RESULTS Actin related protein 2/3 complex subunit 1A (ARPC1A) was identified as the hub gene. ARPC1A was highly expressed in PCa tissues and cell lines, and was an independent prognostic factor for predicting biochemical recurrence after radical prostatectomy and overall survival of PCa patients. Knockdown of ARPC1A inhibited PCa cell migration, invasion and cytoskeleton formation, but had no impact on cell proliferation and cell cycle progression. In vivo, ARPC1A overexpression promoted lung metastasis of PCa, but had no efffect on tumor growth. Additionally, glutamine metabolism was identified as an upstream regulator of ARPC1A, and promoted migration, invasion and cytoskeletal changes of PCa cell through ARPC1A. CONCLUSION These findings suggested that ARPC1A, which correlates with poor prognosis in PCa, functions downstream of glutamine metabolism to regulate cytoskeletal changes, cellular migration and cellular invasion in this disease.

Abstract
AIM To evaluate the differences between human lacrimal gland adenoid cystic carcinoma with high-grade transformation (LACC-HGT) primary cells cultured by high-grade transformation tissue and non-high-grade transformation (non-HGT) primary cells cultured by non-high-grade transformation tissue in proliferation, metastasis, drug susceptibility, and genes. METHODS LACC-HGT primary cells were established by tissue block culture, and the 4th to 10th generation primary cells were selected as research objects. The cells were preliminarily identified by immunofluorescent staining. The differences between non-HGT and LACC-HGT primary cells in terms of proliferation, metastasis, and drug susceptibility were compared by cell counting kit-8 (CCK-8) assay, wound healing, and drug sensitivity experiments. Differentially expressed genes were screened using mRNA array. Gene expression was analyzed using real-time quantitative polymerase chain reaction (RT-qPCR). RESULTS LACC-HGT primary cells were successfully cultured by tissue block culture. Immunofluorescence staining results showed that cytokeratin (CK) and CK7 expression levels were positive in LACC-HGT primary cells. CCK-8 results showed that the proliferation ability of LACC-HGT cells was significantly higher than that of non-HGT cells. Wound healing experiment showed that the migration ability of LACC-HGT cells was significantly higher than that of non-HGT cells. LACC-HGT cells were also less sensitive to cisplatin and paclitaxel than non-HGT cells. Compared with non-HGT cells, 9566 differentially expressed genes were found in LACC-HGT primary cells, of which 5162 were up-regulated and 4404 were down-regulated. The expression of N-acetylneuraminate pyruvate lyase (NPL), MARVEL domain containing 3 (MARVELD3), syntabulin (SYBU), and allograft inflammatory factor 1 (AIF1) was higher in LACC-HGT cells than in non-HGT cells, whereas that of periostin (POSTN) was lower. CONCLUSION LACC-HGT primary cells have faster proliferation, stronger migration ability, and poorer sensitivity to chemotherapy drugs than non-HGT primary cells. The expression of mRNAs in non-HGT and LACC-HGT primary cells are significantly different. These features are speculated to be the reasons why high-grade transformation tissues exhibit higher malignant degree and poorer prognosis than their counterparts.

Abstract
OBJECTIVE This study was to explore the risk factors for postoperative bladder neck contracture (BNC) after transurethral operation of prostate in patients with small-volume prostatic obstruction. METHODS Clinicopathologic data at our center from February 2016 to January 2020 were retrospectively collected and analyzed. Clinicopathological characteristics between patients with and without BNC were compared. Multivariate logistic regression was used to determine the risk factors for postoperative BNC. RESULTS There were a total of 39 patients (8.53%) with postoperative BNC. Multivariate logistic regression analysis demonstrated that preoperative bladder neck diameter (BND), intravesical prostatic protrusion (IPP), surgical methods (transurethral resection of prostate (TURP)/anatomical endoscopic enucleation of the prostate (AEEP)), and postoperative urinary tract infection (UTI) were independent risk factors for postoperative BNC in patients with small-volume prostatic obstruction (P < 0.05). The incidence of postoperative BNC in patients undergoing AEEP was significantly decreased compared with those undergoing TURP. The optimal cut-off value of preoperative IPP was 6.10 mm while the optimal cut-off value of preoperative BND was 2.52 cm. CONCLUSIONS Larger preoperative bladder neck and higher preoperative IPP lead to decreased incidence of postoperative BNC in patients with small-volume prostatic obstruction. Active management of postoperative UTI could effectively prevent the occurrence of postoperative BNC. Compared with TURP, complete AEEP would contribute to reduce BNC in patients with small-volume prostatic obstruction.

Abstract
A 20-year-old girl came to the Tianjin Medical University Eye Hospital because of progressive herniation of her right eye for 3 months. Examination revealed a huge mass behind the right eyeball, which was clinically diagnosed as a space-occupying lesion of the right orbit. Because the tumor was close to the nerve, most of the tumor was resected and pathologically diagnosed as a poorly differentiated leiomyosarcoma. Orbital evisceration was performed later. There was no recurrence during the 10-year follow-up.

Abstract
OBJECTIVE Low muscle mass and quality is associated with poor surgical outcomes. Psoas muscle density (PMD)is a validated surrogate for muscle quality that can be easily measured from a clinical computed tomography (CT) scan. The objective of this study was to investigate the association between PMD and short-term postoperative outcomes in patients with acute mesenteric ischemia (AMI). METHODS From April 2006 and September 2019, the clinical data of all patients who underwent surgical intervention with a preoperative diagnosis of AMI and had preoperative non-contrast CT images available were retrospectively reviewed. PMD was measured by CT at the third lumbar vertebra. The lowest quartile of PMD for men and women in all patients was used as sex-specific cut-off values for low PMD. Univariate and multivariate analyses evaluating risk factors of postoperative complications and 30-day mortality were performed. RESULTS The cohort consisted of 88 patients with a mean age of 58.8 ± 16.2 years, of whom 21 (23.9%) patients had low PMD based on the diagnostic cut-off values (40.5 HU for men and 28.4 HU for women), 35 (39.8%) patients developed complications within 30 days of the operation, and 10 (11.3%) patients died within 30 days of surgery. Low PMD patients had a higher risk of postoperative complications and 30-day mortality than patients without low PMD patients. In a multivariate analysis, low PMD and low psoas muscle area (PMA) were independent predictors of postoperative complications. However, only low PMD remained an independent risk factor for 30-day mortality. CONCLUSIONS Preoperative assessment of the PMD on CT can be a practical method for identifying AMI patients at risk for postoperative complications and 30-day mortality.

Abstract
Objective: To screen the differently expressed microRNAs (miRNAs) and to explore the effect and mechanism of microRNA-3907 (miR-3907) in meibomian gland carcinoma (MGC). Methods: Experimental research. MGC tissues and para-carcinoma tissues of patients diagnosed with MGC by histopathology were collected from July 2011 to January 2019 in Tianjin Medical University Eye Hospital. The miRNA microarray analysis of MGC and para-carcinoma tissue samples from 5 patients was performed. miR-3907 with a significant up-regulation was selected as a research object. Bioinformatics predicted and dual-luciferase gene reporter assay verified miR-3907 target genes. The protein expression levels of target genes in 18 MGC tissues and 6 para-carcinoma tissue samples were determined by immunohistochemical staining. miR-3907 over-expression, miR-3907 knock-down, target gene knock-down and miR-3907 knock-down with target gene knock-down were respectively performed in MGC cell. The mRNA and protein expressions were validated by real-time PCR and Western blotting after transfection. The cell proliferation and migration ability was detected by cell counting kit-8 and scratch experiment after transfection. The main statistical methods were Fisher's exact test, independent sample t test, two-factor repeated measure analysis of variance. Results: There were 22 differently up-regulated miRNAs and 5 differently down-regulated miRNAs in MGC tissues, of which miR-3907 was significantly up-regulated. Thrombospondin-1 (THBS1) was a target gene of miR-3907 according to bioinformatics and dual-luciferase gene reporter assay. The positive expression rate of THBS1 protein in para-carcinoma tissues (6/6) was significantly higher than that in MGC tissues (5/18), and the difference was statistically significant (P=0.003). Compared with the negative control group, the proliferation ability of the miR-3907 over-expression group was increased at 48 h and 72 h (F=3.70, 2.65; both P<0.01), and the migration rate at 24 h was significantly higher (54.6%±3.4% vs. 34.2%±0.6%; t=8.34, P<0.01). Compared with the negative control group, the proliferation ability of the miR-3907 knock-down group was decreased at 24 h, 48 h and 72 h (F=3.10, 2.17, 3.09; all P<0.05), and the migration rate at 24 h was significantly lower (40.8%±2.8% vs. 69.7%±2.7%; t=10.42, P<0.01). Compared with the negative control group, the THBS1 knock-down group promoted cell proliferation at 24 h, 48 h and 72 h (F=3.84, 3.79, 2.24; all P<0.05), and the migration rate at 24 h was significantly increased (82.5%±1.9% vs. 37.6%±5.1%; t=11.74, P<0.01). Compared with the control group, the miR-3907 knock-down with THBS1 knock-down group increased proliferation at 24 h and 48 h (F=3.97, 3.31; both P<0.05), and the migration healing rate at 24 h was significantly increased (56.9%±2.2% vs. 41.9%±4.3%; t=3.53, P<0.05). Conclusions: There are differently expressed miRNAs between MGC and para-carcinoma tissues, which may be related to the occurrence and development of MGC. miR-3907 in MGC tissues has a significant difference from that in para-carcinoma tissues. Moreover, miR-3907 can play a role in promoting proliferation and migration of MGC by inhibiting the expression of THBS1.

Abstract
Background Delamanid (Dlm) is an effective drug against drug-susceptible and drug-resistant Mycobacterium tuberculosis strains, including Multidrug-resistant Mycobacterium tuberculosis (MDR-MTB). There are few reports on the activity and secretion of cytokines caused by Dlm on macrophages infected by MDR-MTB strains. Therefore, this article aims to observe the bactericidal activity and secretion of cytokines of the macrophages infected by MDR-MTB strains after Dlm was administered, so as to provide a basis for further perfecting the mechanism of Dlm. Methods Samples were respectively collected to count the intracellular colony-forming unit (CFU) of macrophages infected by MDR-MTB or H37Rv strains at 4, 8, 24, and 48 h after Dlm at MIC, 10MIC, and 20MIC were administered. Samples were respectively collected to detect the level of IL-12/23 p40, TNF-α, IL-6, and IL-10 in the culture supernatant of macrophages infected by MDR-MTB or H37Rv strains at 4, 24, and 48 h after Dlm at MIC were administered. The levels of four cytokines in the culture supernatant were measured using the Luminex® 200™ (Luminex, USA) according to the manufacturer’s instructions. Data were analyzed by SPSS 25.0 software. The continuous data in normal distribution were expressed as mean ± standard deviation (x¯ ± s) and analyzed by t or F test. P<0.05 was considered statistically significant. Results (1) After Dlm was applied to macrophages infected by MDR-MTB strains: (A) The intracellular CFU gradually decreased, reached the lowest value at 48 h, and was lower than that of Dlm before administration and infection group (P<0.05). (B) The intracellular CFU was further reduced after increasing Dlm dose to 10MIC and 20MIC, and the latter was lower than that of the former (P<0.05). (C) The intracellular CFU of MDR-MTB group was higher than that of H37Rv group at 4~48 h after administration (P<0.05). (2) After Dlm at MIC dose was applied to macrophages infected by MDR-MTB strains: (A) The level of IL-12/23 p40 at any time didn’t change compared with that of Dlm before administration (P>0.05), while the level of IL-12/23 p40 at 4 h was higher than that of the infection group (P<0.05). The levels of TNF-α at 24 and 48 h were higher than that of Dlm before administration (P<0.05), but were similar to that of the infection group (P>0.05). In addition, the levels of IL-12/23 p40 and TNF-α at any time were similar to that of the H37Rv group after administration (P>0.05). (B) The levels of IL-6 at 24 and 48 h were higher than that of Dlm before administration (P<0.05), but were similar to that of H37Rv group (P>0.05) and were lower than that of infection group (P<0.05). The level of IL-10 at any time didn’t change compared with that of Dlm before administration (P>0.05), but was lower than that of the infection group at 4~48 h and was lower than that of the H37Rv group at 24 h (P<0.05). (C) The level of IL-12/23 p40 and IL-10 didn’t change with the change of intracellular CFU (P<0.05), while the level of TNF-α and IL-6 increased with the intracellular CFU decreasing, and the increase level of TNF-α was lower than that of the infection group (P<0.05). Conclusions Dlm had strong bactericidal activity against intracellular MDR-MTB, which was time-dependent and concentration-dependent. Its bactericidal activity against intracellular MDR-MTB strains was weaker than that against drug-susceptible tuberculosis strains. Dlm might have immunomodulatory effect, inducing low expression of Th2 cytokines IL-6 and IL-10 at different times after administration.

Abstract
OBJECTIVE To develop and validate hub genes involving in the development and progression of primary aldosteronism (PA) and adrenal aldosterone-producing adenoma (APA). MATERIALS AND METHODS A total of four datasets of gene expression profiles related to APA were downloaded from GEO datasets. GSE60042 and GSE8514 were used to identify DEGs. Weighted gene co-expression network analysis (WGCNA) and protein-protein interaction (PPI) network module analysis were conducted. GO and KEGG enrichment analysis was performed. GSE10927 and GSE33371 were used for further external validation. RESULTS We identified a total of 892 DEGs from GSE60042 and 1167 DEGs from GSE8514. WGCNA analysis demonstrated that the blue module (255 genes) and turquoise module (303 genes) were significantly correlated with APA. PPI networks were then constructed. GO term enrichment analysis suggested that cellular divalent inorganic cation homeostasis, calcium ion homeostasis, collagen-containing extracellular matrix, transport vesicle and metal ion transmembrane transporter activity were the vital annotations. KEGG pathway analysis found that these genes were significantly enriched in neuroactive ligand-receptor interaction, calcium signaling pathway. Finally, we identified a total of 11 candidate genes involving in the development and progression of APA and PA. Besides, two independent datasets (GSE10927 and GSE33371) were used for external validation, and there were seven hub genes successfully verified, including C3, GRM3, AVPR1A, WFS1, PTGFR, NTSR2, and JUN. CONCLUSION These newly identified genes could contribute to the understanding of potential mechanism in APA and PA and might be promising targets for the treatment of APA and PA.

Abstract
Purpose: To estimate whether the city-specific lockdown in Shanghai induced by the COVID-19 pandemic affected preterm birth rates among uninfected pregnant women in different trimesters. Methods: The population-based retrospective cohort study was conducted in the International Peace Maternity and Child Health Hospital (IPMCH) in Shanghai, China. Pregnant women without COVID-19 received perinatal healthcare during lockdown (from January 24, 2020 to March 24, 2020) and non-lockdown (from January 24, 2019 to March 24, 2019) period and giving birth to a live infant at IPMCH were enrolled. 1:1 propensity score matching and Inverse probability of treatment weighting were used to evaluate preterm birth (<37 weeks), very preterm birth (<34 weeks), preterm birth with premature rupture of membranes (PROM-PTB), spontaneous preterm birth with intact membranes (S-PTB), and medically induced preterm birth (MI-PTB) between two groups. Results: 8,270 pregnant women were in the lockdown group, and 9,815 were in the non-lockdown group. Pregnant women in second trimester during lockdown had a higher risk of PTB than those during the non-lockdown period [OR: 1.43 (CI 1.01–2.02), ARD: 1.7% (CI 0.04–3.4%), p = 0.045]. Furthermore, pregnant women in third trimester during lockdown had a higher risk of PROM-PTB than those during the non-lockdown period [OR: 1.64 (CI 1.09–2.47), ARD: 0.9% (CI 0.2–1.6%), p = 0.02]; no group differences were found related to rates of VPTB, S-PTB or MI-PTB. Conclusion: In this cohort study in China, we found that there was an increased risk in preterm birth for non-infected women in COVID-19 lockdown who were in their second trimester.

Abstract
OBJECTIVE To investigate the influence of prostatic calculi on the results of prostate biopsy in patients with a PSA level of 4-10 μg/L. METHODS We reviewed the clinical data on 317 patients with a PSA level of 4-10 μg/L on prostate biopsy performed in The First Affiliated Hospital of Fujian Medical University between May 2012 and May 2019, concerning age, body mass index (BMI), prostate volume, PSA level, FPSA/TPSA ratio, PSA density (PSAD), scores on Prostate Imaging Reporting and Data System version 2 (PI-RADS), prostatic calculi and pathological findings. Using logistic regression analysis and ROC curves, we evaluated the influence of prostatic calculi on the results of prostate biopsy. RESULTS Multivariate analysis showed that age and the PI-RADS score were independent risk factors of positive prostate biopsy, while the prostate volume, FPSA/TPSA ratio and calculus burden were independent protective factors, and that the PI-RADS score was an independent risk factor of clinically significant PCa, while calculus burden and FPSA/TPSA ratio were independent protective factors. Subgroup analysis of the prostatic calculi revealed that the rates of positive prostate biopsy and clinically significant PCa were higher in the patients with calculi in the peripheral zone than in the other groups, but lower in those with calculi in the central or transitional zone than in the peripheral zone and non-calculus groups. CONCLUSIONS The rates of positive prostate biopsy and clinically significant PCa are low in prostatic calculus patients with a PSA level of 4-10 μg/L, especially in those with calculi in the central or transitional zone.

Abstract
Background Urethral stricture is a clinical challenge for both patients and clinicians. Post-traumatic urethral stricture is associated with formation of scar tissue caused by excessive inflammation. The aim of this study is exploring potential therapeutic strategies for this condition. Methods In vivo experiments on New Zealand rabbits and in vitro experiments on THP-1 monocytes and urethral fibroblasts were performed to investigate the effects on post-traumatic urethral stricture of exosomes isolated from IL-1β-treated mesenchymal stem cells (Exo-MSCsIL-1β) and the role of macrophage M2 polarization in this process. Additionally, related signaling and mechanism behind were explored. Results In a New Zealand rabbit model of post-traumatic urethral stricture, injection of Exo-MSCsIL-1β significantly reduced urethral stricture and collagen fiber accumulation compared with Exo-MSCs. Addition of Exo-MSCsIL-1β to THP-1 monocytes in vitro induced M2 macrophage polarization, which, in turn, inhibited activation of urethral fibroblasts and synthesis of collagen. Mechanistically, Exo-MSCsIL-1β were found to contain high levels of the microRNA let-7c, and luciferase reporter assays showed that let-7c interacted with the 3'UTR of PAK1 mRNA. Transfection of THP-1 cells with a let-7c mimic downregulated PAK1 expression and inhibited activation of the NF-κB signaling pathway. Conclusion These results support a role for let-7c-containing Exo-MSCsIL-1β in reducing urethral stricture via inhibition of PAK1-NF-κB signaling, M2 macrophage polarization, and differentiation of urethral myofibroblasts.

Abstract
Objective: To analyze the protein expression differences of lacrimal gland adenoid cystic carcinoma (LACC) with high-grade transformation (HGT). Methods: Experimental study. A total of 8 paraffin tissue samples were collected in Tianjin Medical University Eye Hospital from December 2012 to January 2019. According to pathological examination, the samples were divided into the LACC group and the LACC-HGT group, with 4 cases in each group. The LACC group included 2 male samples and 2 female samples, with an average age of 53 years. The LACC-HGT group included 2 male samples and 2 female samples, with an average age of 44 years. Primary cells were cultured from fresh tumor tissue. Isobaric tags for relative and absolute quantification techniques were used to screen the differentially expressed proteins between the two groups, and bioinformatics analysis was conducted for the differentially expressed proteins. Microarray was used to screen differentially expressed mRNAs between LACC and LACC-HGT primary cells. The mass spectrum data were intersected with mRNA microarray data, and quantitative real-time (qRT) PCR was performed to verify the results. Proteomics and microarray data were compared using the independent sample t test. The qRT-PCR data were compared pairwise by one-way analysis of variance. Results: A total of 105 HGT-related differential proteins were detected in this study, including 50 up-regulated proteins and 55 down-regulated proteins. The significantly up-regulated proteins included hemoglobin subunit beta, hemoglobin subunit alpha 1, and collagen type Ⅵ alpha 2 chain; the significantly down-regulated proteins included Cereblon, adenosylhomocysteinase like 2, and ribosomal protein L39 pseudogene 5. Gene ontology analysis results showed that the LACC-HGT differential proteins were mainly located in the cytoplasm, vesicle cavity, and extracellular matrix, had organic acid binding and molecular carrier activity, and participated in the regulation of extracellular matrix composition, immunity, inflammation, apoptosis, and other biological processes. Pathway analysis showed that the LACC-HGT differential proteins were mainly involved in signal pathways such as mitogen-activated protein kinase signal pathway and extracellular matrix proteoglycans and glycan metabolism signal pathway. Protein complex prediction analysis screened out 4 up-regulated protein complexes and 1 down-regulated protein complex. There were 15 LACC-HGT differential proteins that overlapped with mRNA chip differential genes, of which 6 were tumor-related proteins including collagen type XIV alpha 1 chain (COL14A1), EMAP like 4 (EML4), inter-alpha-trypsin inhibitor heavy chain 4 (ITIH4), NDRG family member 2 (NDRG2), osteoglycin (OGN) an Ras homolog family member C (RhoC). The main function was the movement and migration of tumor cells. The qRT-PCR results showed that the relative expression levels of COL14A1, EML4, ITIH4, NDRG2, OGN, and RhoC in primary LACC-1, LACC-2, LACC-HGT-1, and LACC-HGT-2 cells were significantly different (F=1 675.98, 38.53, 27.37, 16.47, 13.38, 25.22, all P<0.01). For example, the relative expression of COL14A1 in primary LACC-HGT-1 (16.09±0.51) and LACC-HGT-2 (9.96±0.34) cells was significantly higher than that in primary LACC-1 (1.00±0.13) and LACC-2 (0.67±0.08) cells (all P<0.05). Conclusion: There are differentially expressed proteins between LACC-HGT and LACC, among which COL14A1, EML4, ITIH4, NDRG2, OGN, and RhoC may play an important role in LACC-HGT and can be used as potential targets of LACC-HGT in further study.

Abstract
M2-tumor-associated macrophages (TAMs) work as a promoter in the processes of bone metastases, chemotherapy resistance, and castration resistance in prostate cancer (PCa), but how M2-TAMs affect PCa has not been fully understood. In this study, we analyzed the proportion of tumor-infiltrating immune cells using the CIBERSORT algorithm, based on samples from the Cancer Genome Atlas database. Then we performed weighted gene co-expression network analysis to examine the modules concerning infiltrated M2-TAMs. Gene Ontology analysis and pathway enrichment analysis were performed for functional annotation and a protein–protein interaction network was constructed. The International Cancer Genomics Consortium cohort was used as a validation cohort. The red module showed the most correlation with M2-TAMs in PCa. Biological processes and pathways were mainly associated with the immune-related processes, as revealed by functional annotation. Four hub genes were screened: ACSL1, DLGAP5, KIF23 and NCAPG. Further validation showed that the four hub genes had a higher expression level in tumor tissues than that in normal tissues, and they were good prognosis biomarkers for PCa. In conclusion, these findings contribute to understanding the underlying molecular mechanisms of how M2-TAMs affect PCa, and looking for the potential biomarkers and therapeutic targets for PCa patients.

Abstract
Objective To describe and study the population statistics, hearing phenotype, and pathological changes of a porcine congenital single-sided deafness (CSSD) pedigree. Methods Click auditory brainstem response (ABR), full-frequency ABR, and distortion product otoacoustic emission (DPOAE) were used to assess the hearing phenotype of the strain. Tympanogram was used to assess the middle ear function since birth. Celloidin embedding-hematoxylin-eosin (CE-HE) stain and scanning electron microscopy (SEM) were used to study the pathological changes of cochlear microstructures. Chi-square analysis was used to analyze the relation between hearing loss and other phenotypes. Results The mating mood of CSSD with CSSD was most efficient in breeding-targeted CSSD phenotype (47.62%), and the prevalence of CSSD reached 46.67% till the fifth generation, where 42.22% were bilateral hearing loss (BHL) and 9.00% were normal hearing (NH) individuals. Hearing loss was proved to have no relation with coat color (P = 0.0841 > 0.05) and gender (P = 0.4621 > 0.05) by chi-square analysis. The deaf side of CSSD offspring in the fifth generation had no relation with that of their maternal parent (P = 0.2387 > 0.05). All individuals in this strain exhibited congenital severe to profound sensorineural hearing loss with no malformation and dysfunction of the middle ear. The good hearing ear of CSSD stayed stable over age. The deaf side of CSSD and BHL presented cochlear and saccular degeneration, and the hair cell exhibited malformation since birth and degenerated from the apex to base turn through time. The pathology in BHL cochlea progressed more rapidly than CSSD and till P30, the hair cell had been totally gone. The stria vascularis (SV) was normal since birth and degenerated through time and finally exhibited disorganization of three layers of cells. Conclusion This inbred porcine strain exhibited high and stable prevalence of CSSD, which highly resembled human non-syndromic CSSD disease. This porcine model could be used to further explore the etiology of CSSD and serve as an ideal tool for the studies of the effects of single-sided hearing deprivation on neural, cognitive, and behavioral developments and the benefits brought by CI in CSSD individuals.

Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Ministry of Science and Technology
Background
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare and lethal arrhythmia in children and young adults. RYR2 mutation accounts for 60% of CPVT patients. While many articles about CPVT are published in the Caucasian population, only a few studies are based on Asian ethnicity. A CPVT scorecard proposed using Caucasian patients is proven effective in reducing the burden of variants of uncertain significance (VUS) of RYR2 mutations is not yet tested in the Asian population.
Purpose
Identify mutations among Taiwanese CPVT patients and compare genetic and clinical results with other ethnicities. We also tested the efficacy of the CPVT scorecard in Taiwanese CPVT patients.
Methods
40 clinically diagnosed CPVT patients and their family members were consecutively enrolled from multi-centers. We compared clinical characteristics and genetic results with other ethnicities, and applied the Caucasian CPVT scorecard to test whether it is applicable in Taiwanese CPVT patients.
Results
This is the first nationwide CPVT cohort in Taiwan. Among the 29 patients with CPVT-related gene mutation, 12 RYR2 variants was identified in our cohort with 5 of them unreported in previous studies. The RYR2 yield rate was 55%, similar to other ethnicities. Exercise-induced symptoms including syncope and cardiac arrest were more severe in Taiwanese CPVT cohort, compared to Japanese and Caucasian cohorts. The CPVT scorecard also successfully reduced the VUS rate for the Taiwanese cohort.
Conclusions
Our study demonstrated genetic difference in CPVT patients across ethnicities, suggesting the importance of genetic testing in Taiwan. The CPVT scorecard is applicable to Taiwanese CPVT patients and is a helpful tool in interpreting genetic test results in clinical practice. Clinical characteristics of the cohort Gender (male, %) 15 (52%) Mean age of onset (years) 18 ± 15 Exercise-related syncope or cardiac arrest (n, %) 23 (79%) Exercise-related cardiac arrest (n, %) 14 (48%) Family history of unexplained sudden cardiac death (n, %) 5 (17%) Heart rate (bpm) 73 ± 16 Exercise stress test or Holter positive (n, %) 14 (48%) Ventricular arrhythmia (n, %) 23 (79%) Beta-blockers only (n, %) 10 (35%) Intracardiac defibrillator implantation (n, %) 15 (52%) CPVT score 6 ± 3

Abstract
The diverse tumor cell populations may be the critical roles in relapse and resistance to treatment in prostate cancer patients. This study aimed to identify new marker genes and cell subtypes among castration-resistant prostate cancer (CRPC) cells. We downloaded single-cell RNA seq profiles (GSE67980) from the Gene Expression Omnibus (GEO) database. Principal component (PC) analysis and t-Distributed Stochastic Neighbor Embedding (TSNE) analysis were performed to identify marker genes. CRPC cells were clustered and annotated. GO and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses among marker genes were performed. A total of 1500 genes with larger standardized variance were obtained. The top 20 genes were demonstrated in each identified 20 PCs. PC with P-value < 0.05 was selected, including PC1, PC7, PC8, and PC14. The TSNE analysis classified cells as two clusters. The top 6 genes in cluster 0 included HBB, CCL5, SLITRK4, GZMB, BBIP1, and PF4V1. Plus, the top 6 genes in cluster 1 included MLEC, CCT8, CCT3, EPCAM, TMPRSS2, EIF4G2. The GO analysis revealed that these marker genes were mainly enriched in RNA catabolic process, translational initiation, mitochondrial inner membrane, cytosolic part, ribosome, cell adhesion molecule binding, cadherin binding, and structural constituent of ribosome. The KEGG analysis showed that these marker genes mainly enriched in metabolism associated pathways, including carbon metabolism, cysteine and methionine metabolism, propanoate metabolism, pyruvate metabolism, and citrate cycle pathways. To conclude, our results provide essential insights into the spectrum of cellular heterogeneity within human CRPC cells. These marker genes, GO terms and pathways may be critical in the development and progression of human CRPC.

Abstract
OBJECTIVE To screen several immune-related long non-coding RNAs (lncRNAs) and construct a prognostic model for papillary renal cell carcinoma (pRCC). METHODS Transcriptome-sequencing data of pRCC was downloaded and a prognostic model was constructed. Time-dependent receiver operating characteristic (ROC) curve was plotted and the area under curve (AUC) was calculated. We conducted quantitative reverse transcription polymerase chain reaction (RT-PCR) to verify the model. The gene set enrichment analysis (GSEA) was used to show the connection of our model with immune pathways. RESULT We identified four lncRNAs to constructed the model. The model was significantly associated with the survival time and survival state. The expression-levels of the four lncRNAs were measured and the prognosis of high-risk patients was significantly worse. The two immune-gene sets had an active performance in the high-risk patients. CONCLUSION We constructed a prognostic model in pRCC which provided more reference for treatment.

Abstract
Purpose: To evaluate the diagnostic value of the combination of whole-tumor dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and whole-lesion texture features based on T2-weighted images for cervical cancer with parametrial invasion. Materials and Methods: Sixty-two patients with cervical cancer (27 with parametrial invasion and 35 without invasion) preoperatively underwent routine MRI and DCE-MRI examinations. DCE-MRI parameters (Ktrans, Kep, and Ve) and texture features (mean, skewness, kurtosis, uniformity, energy, and entropy) based on T2-weighted images were acquired by two observers. All parameters of parametrial invasion and non-invasion were analyzed by one-way analysis of variance. The diagnostic efficiency of significant variables was assessed using receiver operating characteristic analysis. Results: The invasion group of cervical cancer demonstrated significantly higher Ktrans (0.335 ± 0.050 vs. 0.269 ± 0.079; p < 0.001), lower energy values (0.503 ± 0.093 vs. 0.602 ± 0.087; p < 0.001), and higher entropy values (1.391 ± 0.193 vs. 1.24 ± 0.129; p < 0.001) than those in the non-invasion group. Optimal diagnostic performance [area under curve [AUC], 0.925; sensitivity, 0.935; specificity, 0.829] could be obtained by the combination of Ktrans, energy, and entropy values. The AUC values of Ktrans (0.788), energy (0.761), entropy (0.749), the combination of Ktrans and energy (0.814), the combination of Ktrans and entropy (0.727), and the combination of energy and entropy (0.619) were lower than those of the combination of Ktrans, energy, and entropy values. Conclusion: The combination of DCE-MRI and texture analysis is a promising method for diagnosis cervical cancer with parametrial infiltration. Moreover, the combination of Ktrans, energy, and entropy is more valuable than any one alone, especially in improving diagnostic sensitivity.

Abstract
Background Evidence indicates that there is an important role for long non-coding RNAs (lncRNA) in numerous cellular processes and that lncRNAs dysregulation contributes to tumor progression. Improved insight into the molecular characteristics of bladder cancer is required to predict outcomes and to develop a new rationale for targeted therapeutic strategies. Bioinformatics methods, including functional enrichment and network analysis combined with survival analysis, are required to process a large volume of data to obtain further information about differentially expressed genes (DEGs) in bladder cancer. This study aimed to explore the role of lncRNAs and their regulation network in bladder cancer. Material/Methods We analyzed bladder cancer data by The Cancer Genome Atlas profiling to identify differentially expressed lncRNAs in bladder cancer. The genes involved in the circlncRNAnet database were evaluated using Kyoto Encyclopedia of Genes and Genomes (KEGG), Gene Ontology (GO), evolutionary relationship analysis, and protein-protein interaction (PPI) networks. Results Two new lncRNAs, ADAMTS9-AS1 and LINC00460, were shown to be differentially expressed in bladder cancer. Patients were divided into 2 groups (high expression and low expression) according to their median expression values. The overall survival and disease-free survival of patients with high ADAMTS9-AS1 bladder cancer were significantly shorter; the expression of LINC00460 had no significant correlation with survival. GO and KEGG analysis of the 2 lncRNA-related genes revealed that these lncRNAs played a vital role in tumorigenesis. Bioinformatics analysis showed that key genes related to LINC00460, including CXCL, CCL, and CSF2, may be related to the development of bladder cancer. The low expression of ADAMTS9-AS1 may influence the survival rate of bladder cancer with the hub gene as a target. Conclusions LncRNA, including LINC00460 and ADAMTS9-AS1, might play a crucial role in the biosynthesis network of bladder cancer. Differential expression results of ADAMTS9-AS1 suggests it may be correlated with a worse prognosis and a shorter survival time. We outlined the biosynthesis network that regulates lncRNAs in bladder cancer. Further experimental data is needed to validate our results.

Abstract
Lymph node metastasis is one of the most important independent risk factors that can negatively affect the prognosis of prostate cancer (PCa); however, the exact mechanisms have not been well studied. This study aims to better understand the underlying mechanism of lymph node metastasis in PCa by bioinformatics analysis. We analysed a total of 367 PCa cases from the cancer genome atlas database and performed weighted gene co-expression network analysis to explore some modules related to lymph node metastasis. Gene Ontology analysis and pathway enrichment analysis were conducted for functional annotation, and a protein-protein interaction network was built. Samples from the International Cancer Genomics Consortium database were used as a validation set. The turquoise module showed the most relevance with lymph node metastasis. Functional annotation showed that biological processes and pathways were mainly related to activation of the processes of cell cycle and mitosis. Four hub genes were selected: CKAP2L, CDCA8, ERCC6L and ARPC1A. Further validation showed that the four hub genes well-distinguished tumour and normal tissues, and they were good biomarkers for lymph node metastasis of PCa. In conclusion, the identified hub genes facilitate our knowledge of the underlying molecular mechanism for lymph node metastasis of PCa.

Abstract
PURPOSE COVID-19 (Coronavirus Disease 2019) was first reported in December 2019 and quickly swept across China and around the world. Levels of anxiety and depression were increased among pregnant women during this infectious pandemic. Thyroid function is altered during stressful experiences, and any abnormality during early pregnancy may significantly affect fetal development and pregnancy outcomes. This study aimed to determine whether the COVID-19 pandemic induces thyroid hormone changes in early pregnant women. METHODS This study comprised two groups of pregnant women in Shanghai in their first trimester - those pregnant women before the COVID-19 outbreak from January 20, 2019, to March 31, 2019 (Group 1) and those pregnant during the COVID-19 outbreak from January 20, 2020, to March 31, 2020 (Group 2). All women were included if they had early pregnancy thyrotropin (TSH), free triiodothyronine (FT3), free thyroxine (FT4), total triiodothyronine (TT3), and total thyroxine (TT4) concentrations, thyroid peroxidase (TPO) antibody or thyroglobulin antibody (TgAb) available and did not have a history of thyroid diseases or received thyroid treatment before or during pregnancy. We used propensity score matching to form a cohort in which patients had similar baseline characteristics. RESULTS Among 3338 eligible pregnant women, 727 women in Group 1 and 727 in Group 2 had similar propensity scores and were included in the analyses. Pregnant women in Group 2 had significantly higher FT3 (5.7 vs. 5.2 pmol/L, P<0.001) and lower FT4 (12.8 vs. 13.2 pmol/L, P<0.001) concentrations compared with those in Group 1. Pregnant women in Group 2 were more likely to develop isolated hypothyroxinemia (11.6% vs. 6.9%, OR, 1.75 [95% CI, 1.20-2.53], P=0.003) than those in Group 1 but had a significantly lower risk of TgAb positivity (12.0% vs. 19.0%, OR, 0.58 [95% CI, 0.43-0.78], P<0.001). CONCLUSION Pregnant women in their first trimester in Shanghai during the COVID-19 outbreak were at an increased risk of having higher FT3 concentrations, lower FT4 concentrations, and isolated hypothyroxinemia. The association between thyroid hormones, pregnancy outcomes, and the COVID-19 outbreak should be explored further.

Abstract
Objective To explore the factors associated with improvement of lower urinary tract symptoms (LUTS) after transurethral plasmakinetic enucleation of the prostate (PKEP) and transurethral resection of the prostate (TURP) in patients with a small-volume prostate and bladder outlet obstruction (BOO). Methods The clinicopathologic data of 257 patients with BOO and a small-volume prostate from January 2013 to January 2018 were retrospectively collected preoperatively, 3 months postoperatively, and 12 months postoperatively. Patients were divided into postoperative success and failure groups based on the IPSS, IPSS-v, and IPSS-s. The relationship between each parameter and the improvement of postoperative LUTS was analyzed. Subgroup analysis was performed to compare the differences between the TURP and PKEP groups. Results Among patients followed up for 3 months postoperatively, multivariate analysis demonstrated that IPP, PUA, and post-PCB were significant predictors of postoperative IPSS improvement; TZI, IPP, and PUA were significant predictors of postoperative IPSS-v improvement; post-PCB and the surgical procedure were significant predictors of IPSS-s improvement; and IPP and PUA were significant predictors of postoperative Qmax improvement. Among patients followed up for 12 months postoperatively, multivariate analysis revealed that IPP, PUA, and post-PCB were significant predictors of postoperative IPSS improvement; PUA was a significant predictor of postoperative IPSS-v improvement; post-PCB was a significant predictor of IPSS-s improvement; and IPP and PUA were significant predictors of postoperative Qmax improvement. The post-PCB was significantly lower in the PKEP than the TURP group and the prostatic calculi removal rate was significantly higher in the PKEP than the TURP group. Conclusion Patients with a greater preoperative IPP and PUA and smaller post-PCB showed greater improvement of postoperative LUTS. PKEP might help to remove calculi from between the transitional and peripheral zones of prostate. Compared with conventional TURP, PKEP may improve the early postoperative storage symptoms of LUTS in patients with a small-volume prostate and BOO.

Abstract
BACKGROUND Numerous patients with clear cell renal cell carcinoma (ccRCC) experience drug resistance after immunotherapy. Regulatory T (Treg) cells may work as a suppressor for anti-tumor immune response. PURPOSE We performed bioinformatics analysis to better understand the role of Treg cells in ccRCC. RESULTS Module 10 revealed the most relevance with Treg cells. Functional annotation showed that biological processes and pathways were mainly related to activation of the immune system and the processes of immunoreaction. Four hub genes were selected: LCK, MAP4K1, SLAMF6, and RHOH. Further validation showed that the four hub genes well-distinguished tumor and normal tissues and were good prognostic biomarkers for ccRCC. CONCLUSION The identified hub genes facilitate our knowledge of the underlying molecular mechanism of how Treg cells affect ccRCC in anti-tumor immune therapy. METHODS The CIBERSORT algorithm was performed to evaluate tumor-infiltrating immune cells based on the Cancer Genome Atlas cohort. Weighted gene co-expression network analysis was conducted to explore the modules related to Treg cells. Gene Ontology analysis and pathway enrichment analysis were performed for functional annotation and a protein-protein interaction network was built. Samples from the International Cancer Genomics Consortium database was used as a validation set.

Abstract
Abstract
Background
Brugada syndrome (BrS) is a sudden arrhythmic death. The prevalence of BrS is higher in the Southeast Asian populations than that in Caucasian patients. A previous genome-wide association study (GWAS) has reported 13 SNPs significantly associated with BrS. However, no study was performed to validate whether these SNPs are enriched in BrS patients in Han Chinese (HC).
Purpose
Evaluating the common variants previously reported in Caucasian BrS patients could be generalized to HC BrS patients in Taiwan
Methods
We genotyped 200 unrelated BrS patients using Affymetrix TWB Array (N=653,291 SNPs, a customized array for HC in Taiwan). The controls are obtained from the Taiwan Biobank (N ≈ 16,000) using the same array. An imputation workflow was shown in Figure 1. To confirm the accuracy of the imputed genotype of each variant, Sanger sequencing was performed in 10% of randomly selected cases.
Results
Among the 3 most important common variants (rs11708996 in SCN5A, rs10428132 in SCN10A and rs9388451 in HEY2/NCOA7) reported in the previous GWAS mainly conducted in Caucasian BrS patients, 2 of them (rs10428132 and rs9388451) were successfully replicated in the HC population in Taiwan (P<0.01). We also found that the differences of minor allele frequency (dMAF: the MAF of cases minus the MAF of controls) of the two variants were relatively smaller between the BrS cases and healthy controls in HC population compared with that in Caucasian populations (dMAF, rs9388451: 0.15 (Caucasian) vs −0.07 (HC); rs10428132: 0.28 (Caucasian) vs 0.11 (HC)). For the remaining 10 common variants reaching genome-wide significance (P=5×10–8) in Caucasian BrS patients, 9 of them were also significantly enriched in the HC BrS patients after the Bonferroni correction (P<0.05/12=0.0042). We next analyzed the variants identified in the previous GWAS on ECG traits (PR interval, QRS duration, QTc interval, and heart rate) in the Caucasian population. Among the reported 75 variants associated with ECG traits, 5 common variants (rs6798015 (PR), rs1760876 (QRS), rs6795970 (PR/QRS), rs2074238 (QTc) and rs314370 (heart rate)) were significant after Bonferroni correction (P<0.05/75=0.00066).
Figure 1
Conclusions
The preliminary results indicated that 85% of common variants of SCN10A and HEY2/NCOA7 previously reported in Caucasian BrS patients are replicated in BrS patients in the HC population but not the common variant of SCN5A (rs11708996). Furthermore, the common variants of SCN10A and HEY2/NCOA7 related to cardiac depolarization or repolarization may also contribute to the development of BrS.

Abstract
Purpose: To investigate the risk factors for progression to castration-resistant prostate cancer (CRPC) in metastatic prostate cancer (mPCa) patients who underwent androgen deprivation therapy (ADT). Methods: We analyzed 216 patients with mPCa who underwent ADT between January 2006 and December 2015 at the First Affiliated Hospital of Fujian Medical University. Univariate and multivariate Cox regression analysis were used to explore the risk factors for progression to CRPC. Kaplan-Meier analysis and log-rank test were used to evaluate the difference in progression-free survival (PFS). Results: A total of 121 (56.0%) patients who underwent ADT showed progression to CRPC. Multivariate Cox regression analysis demonstrated that Gleason grade group, prostate-specific antigen nadir (nPSA), and time to PSA nadir (TTN) were risk factors for progression to CRPC in mPCa patients. Kaplan-Meier analysis demonstrated that patients in Gleason grade group ≥3, nPSA >0.2 ng/ml and TTN <6 months had shorter PFS. Conclusion: This study demonstrated that Gleason grade group, nPSA and TTN were risk factors for progression to CRPC. Patients with higher Gleason grade group, higher nPSA and shorter TTN have shorter PFS and higher risk of progression to CRPC after ADT.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age and its etiology has not been characterized. Growth differentiation factor 8 (GDF8) is a member of the transforming growth factor-β superfamily that plays a critical role in the regulation of ovarian functions. However, the expression pattern of GDF8 in the human ovary is not yet clear. This study examined the cellular distribution of GDF8 and its putative cellular receptors (ACVR2A, ACVR2B, and ALK5) in a series of normal (n = 34) and PCOS ovaries (n = 14). The immunostaining of GDF8, ACVR2A, ACVR2B, and ALK5 was detected in the oocytes regardless of the developmental stage. All these proteins were localized in antral follicles in normal and PCOS ovaries, and the expression of these proteins increased with increasing follicle diameter. A significantly higher expression of GDF8 was detected in the granulosa cells than in the matched theca cells (TCs). These proteins were also localized in the luteal cells of the corpus luteum. Granulosa cells and TCs of large antral follicles in PCOS ovaries display a higher expression of these proteins. The higher expression levels of GDF8 and its functional receptors (ACVR2A, ACVR2B, and ALK5) in antral follicles of PCOS ovaries than those in normal ovaries suggest the possible involvement of dysregulated GDF8 in the pathogenesis of PCOS.

Abstract
The purpose of this study was to explore levels of organizational commitment, job satisfaction and work engagement among community health-care workers in China, and to examine spatial relationships of variables. Data were collected by Organizational Commitment Scale, Job Satisfaction Scale and Utrecht Work Engagement Scale from 1404 community health-care workers in Guangzhou and Shenzhen cities. Structural equation model was used to analyze relationships among three variables. Medium levels of organizational commitment, job satisfaction and work engagement were found among community health-care workers. Organizational commitment was positively correlated to work engagement (r = 0.564) and job satisfaction (r = 0.550). The path analysis indicated that total effect (β = 0.598) of organizational commitment on job satisfaction (R 2 = 0.52) consisted of a direct effect (β = 0.264) and an indirect effect (β = 0.334), which was mediated positively by work engagement. Improvement in work engagement may lead to higher level of job satisfaction and organizational commitment.

Abstract
Background Risk factors of visceral metastases in prostate cancer (PCa) patients are unclear. The aim of this study is to investigate the risk factors of developing visceral metastases at diagnosis and the impact of these risk factors on the survival of patients with visceral metastatic PCa. Methods Patients with visceral metastases at the time of diagnosis of [2010–2015] PCa were identified using the Surveillance, Epidemiology, and End Results (SEER) database. Visceral metastatic distribution data were provided for liver, lung, and brain. The overall survival (OS) was calculated by the Kaplan-Meier method. Multivariable logistic and Cox regression models were performed to identify risk factors and analyze survival outcomes. Results A total of 13,092 eligible patients with stage IV PCa were identified from SEER database. A total of 598 patients developed visceral metastases at diagnosis among these patients. In multivariable analyses, patients with PSA >80 ng/mL had 1.545-fold higher risk of developing visceral metastases compared with those with PSA <20 ng/mL (P<0.001). The presence of bone metastasis and lymph node (LN) metastases were represented as risk factors of visceral metastases in stage IV PCa patients. Patients with two or three metastatic sites had 1.604-fold higher risk of shorter OS compared with those with one metastatic site (P<0.05). And patients with bone plus visceral metastases had 1.410-fold higher risk of shorter OS compared with those with visceral metastasis only (P<0.05). Age ≥70 had 1.621-fold higher risk of shorter OS compared with those with age <70 (P<0.05). T4 stage had 1.476-fold higher risk of shorter OS compared with those with T1 stage (P<0.05). Conclusions The incidence rate was increased among patients with visceral metastases in stage IV PCa at diagnosis. PSA over 80 ng/mL, the presence of bone metastasis and the presence of LN metastases were risk factors associated with a higher rate of development of visceral metastases in stage IV PCa patients. The presence of visceral plus bone metastases, two or three sites, age over 70, and T4 stage represent prognostic factors on survival outcomes in visceral metastatic PCa patients.

Abstract
Background: Seminoma accounts for the most part of cases of testicular germ cell tumor, which is the most common malignancy among males between ages 15 and 44 years. Understanding the molecular mechanism of tumorigenesis is important for better clinical diagnosis and treatment. Purpose: We performed bioinformatics analysis to better understand seminoma at the genetic level and to explore potential candidate genes or molecules for diagnosis, treatment, and prognosis. Methods: A gene expression profile (GSE8607), containing 40 seminoma samples and three healthy testes samples, was analyzed to identify differentially expressed genes (DEGs) associated with the occurrence of seminoma. Functional annotation was then performed using gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses. Cytoscape with Search Tool for the Retrieval of Interacting Genes was used to construct a protein–protein interaction (PPI) network of the DEGs and select hub genes. Moreover, validation of expression level and Kaplan–Meier analysis for overall survival were conducted to those hub genes. Results: A total of 1,636 DEGs were identified between seminoma and healthy samples, including 701 up-regulated in seminoma that were enriched in the regulation of immune responses, defense responses, receptor activity, and signal transducer activity; 935 were down-regulated in seminoma and were associated with reproductive processes, kinase activity, and carbohydrate derivative binding. Five hub genes were selected from the PPI network according to the degree of connectivity: IL6, VEGFA, IL10, CCR5, and CXCR4. Among them, high expression levels of CCR5 and CXCR4 were associated with poor prognosis for seminoma patients. Four modules selected from the PPI network revealed that seminoma was connected with the Janus kinase-signal transducers and activators of transcription signaling pathway, chemokine signaling pathway, endocytosis, and cytokine–cytokine receptor interaction. Conclusion: These identified DEGs and hub genes facilitate our knowledge of the underlying molecular mechanism of seminoma and have the potential to be used as diagnostic biomarkers or therapeutic targets for seminoma.

Abstract
Objective: To investigate the clinical, imaging and pathological features of adult onset xanthogranuloma. Methods: Retrospective case series study.The clinical data of 4 adult patients with adult onset xanthogranuloma treated in the Tianjin Medical University Eye Hospital from 2015 to 2017 were analyzed. Results: There were 1 male and 3 females, aged 46-73 years, with an average age of 55 years. The duration of eyelid swelling was from 6 months to 6 years. One case was binocular and 3 cases were monocular. There were progressive enlargement of eyelid swelling and subcutaneous cord nodules with poor mobility and no tenderness in all 5 eyes. The eyelid skin in 2 patients (2 eyes) was bulging and yellow. CT examination showed swelling of the eyelids and soft tissue thickening in 5 eyes. There were lacrimal gland enlargement in 3 eyes, upper rectus muscle involvement in 3 eyes, external rectus muscle involvement in 1 eye, lower rectus muscle involvement in 1 eye, superior oblique muscle involvement in 1 eye, and involvement of both the superior and inferior rectus muscles in 1 eye. In 1 patient (1 eye), the lesion showed low and medium signals on T(1) weighted images and T(2) weighted images. Three patients (4 eyes) underwent color Doppler ultrasonography, showing the echo zone in the irregularly shaped eyelid was strong, the internal echo was uneven, the local echo was low, and the boundary was not clear. One of the eyes showed a blood flow signal. All patients underwent surgical resection. The pathological results showed infiltration of foamy tissue cells, Touton cells, lymphocytes and plasma cells. Immunohistochemistry demonstrated 3 patients (4 eyes) expressed CD68, and 1 patient (1 eye) expressed S-100. After 6 months to 2 years of follow-up, 3 patients had no recurrence. One patient developed eye discomfort at 6 months after surgery, and the symptoms were relieved after treatment with triamcinolone. Conclusions: Adult onset xanthogranuloma mainly manifest as eyelid swelling, periorbital mass and skin color changes, generally with no systemic involvement. Imaging examination mainly shows the involvement of soft tissues, lacrimal glands and muscles around the eyelids. The main features of the pathology are infiltration of foamy tissue cells, Touton giant cells, lymphocytes and plasma cells. (Chin J Ophthalmol, 2019, 55: 381-386).

Abstract
OBJECTIVE To investigate the influence of the degrees of intravesical prostatic protrusion (IPP) on the recovery of urinary continence after radical prostatectomy. METHODS We retrospectively analyzed the clinical data on 212 patients diagnosed with prostate cancer by biopsy and treated by laparoscopic radical prostatectomy by the same surgeon. Based on the degrees of IPP measured by MRI, we divided the patients into an IPP ≤ 10 mm group (n = 146) and an IPP > 10 mm group (n = 66) and determined the factors influencing the recovery of urinary continence by univariate and multivariate logistic regression analyses. RESULTS At 1, 3, 6 and 12 months after surgery, the urinary continence rates of the patients were 32.5%, 50.5%, 82.1% and 91%, respectively. Univariate analysis indicated that the factors influencing the recovery of urinary continence included IPP, body mass index (BMI), bladder neck preservation (BNP), neurovascular bundle preservation (NVBP) and clinical tumor (T) stage at 3 months (P < 0.05 or P < 0.01), age, IPP, BMI, BNP and clinical T stage at 6 months (P < 0.05 or P < 0.01), and age, IPP, BMI, BNP, NVBP and clinical T stage at 12 months (P < 0.05), while multivariate logistic regression analysis showed the independent influencing factors to be IPP > 10 mm (P < 0.001), BMI ≥ 25 kg/m2 (P = 0.004) and BNP (P = 0.032) at 3 months, and IPP and BMI at 6 months (both P < 0.01) and 12 months (P < 0.01 and P = 0.033). CONCLUSIONS IPP > 10 mm and BMI ≥ 25 kg/m2 are independent factors influencing the long-term recovery of urinary continence after radical prostatectomy.

Abstract
Purpose To examine the effects and mechanism of action of fasudil on cytoskeletal polymerization, collagen synthesis, and apoptosis in fibroblasts derived from human urethral scar tissue. Materials and methods Fibroblasts treated with or without transforming growth factor β1 (TGF-β1, 10 ng/mL) were incubated with fasudil (12.5, 25, 50 μmol/L) for 24 hours. Quantitative real-time polymerase chain reaction and Western blotting were used to determine the expression of Arp2, Arp3, WASP, and WAVE2. Collagen I and III protein levels were also evaluated by Western blotting. The filamentous actin cytoskeleton was examined by immunofluorescence and epifluorescence microscopy. An Annexin V-FITC/PI staining assay was used to investigate apoptosis. Results TGF-β1-dependent induction of actin polymerization and collagen synthesis and promotion of apoptosis were dose dependent. When compared with untreated controls, fasudil significantly decreased the expression of Arp2, Arp3, WASP, WAVE2, Collagen I, and Collagen III in cells treated with or without TGF-β1. Fasudil also promoted apoptosis in cells, irrespective of TGF-β1 treatment. Conclusion Irrespective of TGF-β1 activation status, fasudil suppressed actin polymerization and collagen synthesis and induced apoptosis in human urethral scar fibroblasts via the Rho/ROCK signaling pathway.

Abstract
Objective: To summarize the treatment outcomes of embolizing orbital vascular malformation with intracavitary injection of medical glue during surgery. Methods: A retrospective case series study was performed on 25 patients with orbital vascular malformation who were treated at Tianjin Medical University Eye Hospital during March 2008 and March 2016. In the 25 patients(25 eyes), 7 were male and 18 were female. The range of age was 2-64 years and the median age was 29 years. The clinical features, operation records, pathological reports and follow-up data were analyzed. Results: The location of vascular malformation involved intraorbital in 11 cases and superficial area of eyelid and(or) face in 5 cases, as for the rest 9 cases, both intraorbital and superficial area were involved. Conjunctiva was involved in 4 patients. Clinical manifestation included intermittent protopsis or mass volumn changed (7 cases), pulsating exophthalmos and vascular murmur (1 case). Imaging examination showed solitary mass with regular shape in 5 cases and space occupying lesion with irregular shape and ill-defined margins in 20 cases. Optic nerve was involved in 7 cases. Surgical debulkling were performed via skin incision on the mass surface (in 3 cases), lateral orbitotomy (in 2 cases), and anterior orbitotomy (in 20 cases). The anterior orbitotomy approaches include skin incision under eyebrow (9 cases), skin incision under lower eyelid eyelash (3 cases), transconjunctiva joint lateral canthus incision (6 cases) and transconjunctiva incision only(2 cases). The intra-orbital part of vascular malformation involved intraconal compartment (10 cases) and extraconal compartment (10 cases). During the operation, vascular malformations were exposed and injected with medical aural and encephalic glue. The amount of injected glue ranged from 0.25 ml to 2.50 ml in divided doses. When the soft venous malformations turned hard, the lesions and remnant glue were fully removed. The whole procedure cause less bleeding and shorter time of operation. Histopathologic diagnosis were intraosseous hemangioma (1 case), arteriovenous malformation (2 cases), venous malformation (22 cases), including varix (4 case) and venous hemangioma (18 cases). One patient suffered from sudden central retinal artery embolism on the third day postoperatively, in which case, visual acuity recovered to 0.6 by timely rescue and appropriate procedure. Topical skin aseptic inflammation took place at the same side of medical glue injection in 3 cases which might be caused by medical glue. These 3 cases had superficial eyelid lesions. Postoperative follow up for patient was conducted from 6 months to 5 years. One young patient underwent recurrent orbital hematoma and many times surgery. Conclusions: Embolization of orbital vascular malformation with medical glue injection intraoperatively can be utilized as an easy approach to control hemorrhage. The surgeon should be careful with the application methods, for instance not to push too quickly, not to pass through the vascular malformation, and to remove the lesions and remnant glue completely, in order to avoid complications.

Methods: A retrospective case series study. Seven orbital disease patients who were treated at Tianjin Medical University Eye Hospital between March 2013 and May 2017 were included. All patients, imaging pictures showed enlargement of the infraorbital nerve. The medical histories, clinical featuers, imaging features, pathologies, serological examinations, therapeutic processes and prognosis were collected and analyzed. Results: The 7 patients included 4 males and 3 females aged from 55 to 68 years (the average age was 60). Bilateral involvement was present in 5 of 7 patients. The main clinical manifestations include proptosis, increasing of orbital pressure, impairment of visual functions, reduction in ocular motility, facial sensation, periocular ache, involvement of lymph node and salivary gland, etc. CT results showed enlargement of infraorbital nerve, accompanied with or without the destruction of bone. The inflammatory response may involve with extraocular muscles and lacrimal glands, or were shown as lesions with irregular shape and blurred borders. The MR images generally showed equal T(1) and equal T(2) signal, accompanied with evident enlargement of the infraorbital nerve. Of all the 7 patients, 6 underwent operation, and the pathology confirmed that 2 of the 6 were involved with inflammatory pseudotumors and the rest 4 were involved with IgG4-related ophthalmic disease (IgG4-ROD). The level of IgG4 in the serum were detected for 4 patients, the results of 3 were high and the other was normal. Of all the 7 patients,1 patient underwent conservative treatment, but disease recurred for several times, and the serum IgG4 level for the patient was higher than normal;1 inflammatory pseudotumor patient was cured completely only by surgery, and has a favourable prognosis; 1 IgG4-ROD patient accepted glucocorticoid, surgery, radiotherapy and chemotherapy, but disease recurred several times; The rest of the patients accepted glucocorticoid and operation, 2 were sensitive to glucocorticoid, 2 were not sensitive, and 1 involved with recurrence. Conclusions: If orbital nonspecific inflammation response was accompanied with enlargement of infraorbital nerve, it is suggested that patient is more likely to be involved with IgG4-ROD;Pathology and serological tests can be used for the diagnosis of IgG4-ROD, however treatment effect appears to be poor for most patients, and patients prone to relapse.

Abstract
Cucurbitadienol has anti-inflammation, anti-cancer activities, and acts as a precursor of traditional Chinese medicine active ingredients mogroside and cucurbitacine. For construction of a Sacchromyces cerevisiae cell factory for production of cucurbitadienol, we firstly cloned a cucurbitadienol synthase (CBS) gene from Siraitia grosvenorii. Then, through heterologous expression of CBS in the triterpenoid chassis strain WD-2091, the engineered strain could produced 27.44 mg•L ⁻¹ cucurbitadienol, which was determined by GC-MS. Further regulation of CBS expression led to cucurbitadienol's titer increasing by 202.07% and reaching 82.89 mg•L ⁻¹ in the shake flask fermentation and 1 724.10 mg•L ⁻¹ in the high cell density fermentation. Our research promotes the cucurbitane-type tetracyclic triterpenoids synthesis pathway analysis progress and provides the basis for further obtaining cell factories for production of cucurbitadienol tetracyclic triterpenoids.

Abstract
Antrodia cinnamomea (AC) exhibits many bioactivities, including anti-inflammatory, anti-cancer, and hepatoprotection activities. Many researchers have studied the functions of the components or fractions of AC, but the functions of the original extractions of AC have not been studied. In addition, the detailed relationship between AC and immune-related signaling pathways is unclear. In this study, we screened the effects of CCM111, which is the extract of AC, on seven immune-related signaling pathways and further investigated whether CCM111 can influence inflammation. Interestingly, our results showed that CCM111 significantly inhibited the IL-6-stimulated STAT3 pathway and the LPS-stimulated NF-κB pathway in macrophages. CCM111 also decreased the phosphorylation of STAT3, Tyk2 and the nuclear translocation of p65. Moreover, CCM111 and F4, a fraction of CCM111, down-regulated nitric oxide (NO) production, the protein levels of iNOS and COX-2, and inflammatory cytokines in macrophage cells. Therefore, our study suggested that CCM111 has the potential to be developed as an effective anti-inflammatory agent.

Abstract
PURPOSE To investigate the effect of sintering temperature on mechanical properties of dental zirconia toughened alumina (ZTA) ceramics prepared by gel-casting technique. METHODS The samples prepared by gel-casting were sintered at 1100, 1200, 1250, 1300 and 1400degrees centigrade for each group. The flexural strength, fracture toughness, Vickers hardness and brittleness index were obtained and microscopic morphology of each group was observed under scanning electron microscope (SEM). The data were statistically analyzed using SPSS 19.0 software package. RESULTS The flexural strength, fracture toughness and Vickers hardness increased with the increasing sintering temperature during 1100~1400degrees centigrade. The lowest brittleness index (0.74±0.16) μm-1/2 was observed in group sintered at 1200degrees centigrade and the highest (2.76±0.14) μm-1/2 was at 1400degrees centigrade (P<0.05), while the flexural strength of these two groups was (46.89±3.24) MPa and (349.64±54.72) MPa, respectively. CONCLUSIONS The ZTA dental ceramics exhibit good machinability with proper sintering temperature (1200degrees centigrade) and the strength meets the requirement of clinical application.

Abstract
The effect of three kinds of anti-site disorder to electronic structure and magnetic properties of the LiMgPdSb-type CoMnTiSi alloy are investigated. It was found the Mn-Ti anti-site disorder can induce the diluted magnetism in CoMnTiSi matrix. The magnetic structure has an oscillation between the ferromagnetic and antiferromagnetic states with the different degree of Mn-Ti anti-site disorder. Two novel characteristics: the diluted antiferromagnetic half-metallicity and the diluted zero-gap half-metallity are found in the different degree range of the Mn-Ti anti-site disorder. The Co-Mn and Co-Ti anti-site disorder have little effect on the magnetic properties. The width of energy gap and the intensity of DOS at the Fermi level can be adjusted by the degree of Co-Mn or Co-Ti anti-site disorder. The independent control to the carrier concentration and magnetization can be realized by introducing the different anti-site disorder.

Abstract
BACKGROUND The aim of this meta-analysis was to compare the feasibility of en bloc transurethral resection of bladder tumor (ETURBT) versus conventional transurethral resection of bladder tumor (CTURBT). METHODS Relevant trials were identified in a literature search of MEDLINE, EMBASE, Cochrane Library, Web of Science, and Google Scholar using appropriate search terms. All comparative studies reporting participant demographics, tumor characteristics, study characteristics, and outcome data were included. RESULTS Seven trials with 886 participants were included, 438 underwent ETURBT and 448 underwent CTURBT. There was no significant difference in operation time between 2 groups (P = 0.38). The hospitalization time (HT) and catheterization time (CT) were shorter in ETURBT group (mean difference[MD] -1.22, 95% confidence interval [CI] -1.63 to -0.80, P < 0.01; MD -0.61, 95% CI -1.11 to -0.11, P < 0.01). There was significant difference in 24-month recurrence rate (24-month RR) (odds ratio [OR] 0.66, 95% CI 0.47-0.92, P = 0.02). The rate of complication with respect to bladder perforation (P = 0.004), bladder irritation (P < 0.01), and obturator nerve reflex (P < 0.01) was lower in ETURBT. The postoperative adjuvant intravesical chemotherapy was evaluated by subgroup analysis, and 24-month RR in CTURBT is higher than that in ETURBT in mitomycin intravesical irrigation group (P = 0.02). CONCLUSION The first meta-analysis indicates that ETURBT might prove to be preferable alternative to CTURBT management of nonmuscle invasive bladder carcinoma. ETURBT is associated with shorter HT and CT, less complication rate, and lower recurrence-free rate. Moreover, it can provide high-qualified specimen for the pathologic diagnosis. Well designed randomized controlled trials are needed to make results comparable.

Abstract
The present study aimed to investigate the expression of protease-activated receptor 1 (PAR1) and tumor necrosis factor (TNF)-α in a rat model of subarachnoid hemorrhage (SAH)-induced cerebral vasospasm (CVS). The rat models were established by twice injecting blood into the cisterna magna, after which the following experimental groups were established: The normal group, the SAH3d group, the SAH5d group and the SAH7d group. The rats were perfused and the basilar artery was removed for histological examination. The cross-sectional area of the basilar artery lumen was measured using computer software; and the protein expression of PAR1 and TNF-α was detected by immunohistochemistry. The cross-sectional area of the basilar artery of the rats in the SAH model groups was significantly decreased in a time-dependent manner, as compared with the normal group. The protein expression of PAR1 and TNF-α in the SAH3d, SAH5d and SAH7d groups was significantly increased over time (P<0.05), as compared with the normal group. CVS was detected in the basilar artery, and was associated with wall thickening and significant narrowing of the lumen, thus suggesting that the present model may be used for investigating cerebrovascular disease following SAH. The immunohistochemical analyses demonstrated that the protein expression of PAR1 and TNF-α was significantly increased in the basilar artery of the SAH model rats, and were positively correlated with the degree of CVS.
