Abstract
PURPOSE Circular RNAs (circRNAs) are products of alternative splicing with roles as competitive endogenous RNAs or microRNA sponges, regulating gene expression and biological processes. However, the involvement of circRNAs in herpes simplex keratitis remains largely unexplored. METHODS This study examines circRNA and miRNA expression profiles in primary human corneal epithelial cells infected with HSV-1, compared to uninfected controls, using microarray analysis. Bioinformatic analysis predicted the potential function of the dysregulated circRNAs and microRNA response elements (MREs) in these circRNAs, forming an interaction network between dysregulated circRNAs and miRNAs. RESULTS A total of 332 circRNAs and 16 miRNAs were upregulated, while 80 circRNAs and six miRNAs were downregulated (fold change ≥2.0 and p < 0.05). Gene ontology (GO) and KEGG pathway analyses were performed on parental genes of dysregulated circRNAs to uncover potential functions in HSV-1 infection. Notably, miR-181b-5p, miR-338-3p, miR-635, and miR-222-3p emerged as pivotal miRNAs interacting with multiple dysregulated circRNAs. CONCLUSIONS This comprehensive study offers insights into differentially expressed circRNAs and miRNAs during HSV-1 infection in corneal epithelial cells, shedding light on circRNA-miRNA interactions' potential role in herpes simplex keratitis pathogenesis.

Abstract
ABSTRACT Renal hemangioblastoma (HB) is a rare subset of HBs arising outside of the central nervous system (CNS), with its molecular drivers remaining entirely unknown. There were no significant alterations detected in previous studies, including von Hippel-Lindau gene alterations, which are commonly associated with CNS-HB. This study aimed to determine the real molecular identity of renal HB and better understand its relationship with CNS-HB. A cohort of 10 renal HBs was submitted for next-generation sequencing technology. As a control, 5 classic CNS-HBs were similarly analyzed. Based on the molecular results, glycoprotein nonmetastatic B (GPNMB) immunohistochemistry was further performed in the cases of renal HB and CNS-HB. Mutational analysis demonstrated that all 10 renal HBs harbored somatic mutations in tuberous sclerosis complex 1 (TSC1, 5 cases), TSC2 (3 cases), and mammalian target of rapamycin (2 cases), with the majority classified as pathogenic or likely pathogenic. The CNS-HB cohort uniformly demonstrated somatic mutations in the von Hippel-Lindau gene. GPNMB was strong and diffuse in all 10 renal HBs and completely negative in CNS-HBs, reinforcing the molecular findings. Our study reveals a specific molecular hallmark in renal HB, characterized by recurrent TSC/mammalian target of rapamycin mutations, which defines it as a unique entity distinct from CNS-HB. This molecular finding potentially expands the therapeutic options for patients with renal HB. GPNMB can be considered for inclusion in immunohistochemical panels to improve renal HB identification.

Abstract
Objective: To investigate the gene mutation of telomerase reverse transcriptase (TERT) promoter in inverted urothelial lesions of the bladder and its significance in differential diagnosis. Methods: From March 2016 to February 2022, a total of 32 patients with inverted urothelial lesions diagnosed in Department of Pathology at Qingdao Chengyang People's Hospital and 24 patients at the Affiliated Hospital of Qingdao University were collected, including 7 cases of florid glandular cystitis, 13 cases of inverted urothelial papilloma, 8 cases of inverted urothelial neoplasm with low malignant potential, 17 cases of low-grade non-invasive inverted urothelial carcinoma, 5 cases of high-grade non-invasive inverted urothelial carcinoma, and 6 cases of nested subtype of urothelial carcinoma were retrospectively analyzed for their clinical data and histopathological features. TERT promoter mutations were analyzed by Sanger sequencing in all the cases. Results: No mutations in the TERT promoter were found in the florid glandular cystitis and inverted urothelial papilloma. The mutation rates of the TERT promoter in inverted urothelial neoplasm with low malignant potential, low grade non-invasive inverter urothelial carcinoma, high grade non-invasive inverted urothelial carcinoma and nested subtype urothelial carcinoma were 1/8, 8/17, 2/5 and 6/6, respectively. There was no significant difference in the mutation rate of TERT promoter among inverted urothelial neoplasm with low malignant potential, low-grade non-invasive inverted urothelial carcinoma, and high-grade non-invasive inverted urothelial carcinoma (P>0.05). All 6 cases of nested subtype of urothelial carcinoma were found to harbor the mutation, which was significantly different from inverted urothelial neoplasm with low malignant potential and non-invasive inverted urothelial carcinoma (P<0.05). In terms of mutation pattern, 13/17 of TERT promoter mutations were C228T, 4/17 were C250T. Conclusions: The morphology combined with TERT promoter mutation detection is helpful for the differential diagnosis of bladder non-invasive inverted urothelial lesions.

Abstract
Objective: To clarify the clinicopathological, especially molecular, features of early-onset gastric cancer with the aim of informing analysis of treatment strategies. Methods: In this retrospective case-control study, we examined data from a dedicated gastric cancer database in Zhongshan Hospital affiliated to Fudan University. The original cohort comprised 2506 patients with gastric cancer who had undergone gastrectomy in Zhongshan Hospital Fudan University from July 2020 to October 2021, including 198 with early-onset gastric cancer (aged ≤45 years) and 2,308 with non-early gastric cancer. We used a simple random sampling method to select 396 of the 2,308 patients aged >45 years (ratio of 1:2) as the control group and then compared molecular diagnostic data and clinicopathological features of the two groups. Results: The median age was 39 years in the early-onset gastric cancer group, while 66 years in the control group. The clinicopathological features of early-onset gastric cancer included female predominance (59.1% [117/198] vs. 27.8% [110/396], χ2=54.816, P<0.001), less comorbidity (32.3% [64/198] vs. 57.1% [226/396], χ2=32.355, P<0.001), poorer differentiation (93.9% [186/198] vs. 74.5% [295/396], χ2=30.777, P<0.001) and higher proportion of diffuse type (40.4% [80/198] vs. 15.9% [63/396], χ2=69.639, P<0.001), distant metastasis (7.1% [14/198] vs. 2.8% [11/396], χ2=6.034, P=0.014). Regarding treatment, distal gastrectomy was more commonly performed than proximal gastrectomy (55.1% [109/198] vs. 47.0% [186/396], 1.5% [3/198] vs. 8.3% [33/396], χ2=11.644, P=0.003). Family history of gastric cancer, TNM stage, tumor size, lymph node dissection, nerve invasion, nodes harboring metastases, range of lymph node dissection, digestive tract reconstruction procedure, implementation of laparoscopic surgery, combined resection, and preoperative treatment did not differ significantly between the two groups (all P>0.05). Molecular diagnosis showed there was a smaller percentage of mismatch repair deficiency in the early-onset gastric cancer than in the control group (1.0% [2/198] vs. 10.1% [40/396], χ2=16.301, P<0.001), and a higher rate of positivity for Claudin 18.2 (77.8% [154/198] vs. 53.0% [210/396], χ2=5.442,P<0.001). HER-2 and Epstein-Barr virus positivity rates did not differ significantly between the two groups. Conclusion: Early-onset gastric cancer is a distinct type of gastric cancer with a high degree of malignancy, and treatment targeting Claudin 18.2 may be effective.

Abstract
The initial clinical manifestations of pulmonary artery involvement in Takayasu arteritis were complicated and non-specific, making early diagnosis difficult. Three cases of Takayasu arteritis with pulmonary artery involvement (TA-PAI) initially presenting as community-acquired pneumonia (CAP) were reported. The clinical characteristics and lab test results of the three cases were summarized, and the relevant literature on TA-PAI mimicking CAP was concomitantly reviewed. It might be helpful in the early recognition and diagnosis of such patients.

Abstract
Objective: To investigate the clinicopathological characteristics of testicular biopsies from Klinefelter syndrome (KS) patients. Methods: The testicular biopsy specimens of 87 patients with KS (a total of 107 biopsy specimens) were collected from the Department of Pathology, Peking University Third Hospital, Beijing, China from January 2017 to July 2022. All patients were diagnosed as KS by peripheral blood karyotyping analysis. The testicular histopathologic features, testicular volume and hormone levels were evaluated retrospectively. The histopathologic analysis was used to assess the quantity and morphology of Leydig cells, the spermatogenic state of seminiferous tubules, the thickening of the basement membrane of seminiferous tubules and the changes of stroma. Results: Leydig cell proliferative nodules were seen in 95.3% (102/107) of KS testicular biopsy tissues. The eosinophilic inclusion bodies and lipofuscin in Leydig cells were found in 52.3% (56/107) and 57.9% (62/107) of specimens, respectively. The Sertoli cell only seminiferous tubules and the hyalinized tubules were found in 66.4% (71/107) and 76.6% (82/107) of the examined tissues, respectively. The tubules with complete spermatogenic arrest were found in 15.9% (17/107) of specimens, and 5.6% (6/107) of the specimens showed low spermatogenesis or incomplete spermatogenic arrest. In 85.0% (91/107) of the specimens, increased thick-walled small vessels with hyaline degeneration were identified. Conclusions: The most common features of KS testicular specimens are Leydig cell proliferative nodules, hyaline degeneration of seminiferous tubules and proliferation of thick-walled blood vessels. Testicular biopsy specimens of KS are rare. The pathologists can make a tentative diagnosis of KS based on the histological findings, combined with the ultrasound and laboratory results, which is helpful for further diagnosis and treatment of KS.

Abstract
Objective: To evaluate the effect of fluoroscopy-free technique in the arthroscopic treatment of femoroacetabular impingement syndrome (FAIS). Methods: A retrospective cohort study. Clinical data of FAI patients treated with hip arthroscopy in the No.4 Medical Center, PLA General Hospital from October 2018 to December 2021 were retrospectively analyzed. The patients were divided into two groups according to the surgical procedure: the fluoroscopy group and the fluoroscopy-free group. The operation time and modified Harris hip score (mHHS), international hip outcome tool (iHOT12) and visual analogue scale (VAS) of hip joint pain before and after the operation were observed and compared between the two groups. And the incidence of surgical complications in the two groups were compared too. Results: A total of 460 patients (213 males and 247 females) [aged (32.6±8.3) years (15-67 years)] with valid follow-up were included in this study. There were 275 cases in the fluoroscopy-free group and 185 cases in the fluoroscopy group. The operation time was shorter in the fluoroscopy-free group when compared with that in the fluoroscopy group, and the difference was statistically significant [(93.36±12.54) min vs (115.62±6.03) min, P<0.001]. In both groups, the VAS scores decreased and the mHHS scores and iHOT12 scores improved significantly at the last follow-up when compared with those before the operation (all P<0.001); however, there was no significant difference in the scores between the two groups (all P>0.05). The complication rate in the fluoroscopy-free group was 10.18% (28/275), and it was 10.81%(20/185) in the fluoroscopy group (P=0.829). Conclusion: Fluoroscopy-free hip arthroscopy technique for FAI can avoid radiation and shorten the operation time, but it does not increase the incidence of complications with reliable clinical outcomes.

Abstract
BACKGROUND Studies have shown oxidative stress and apoptosis are the main pathogenic mechanisms of renal ischemia/reperfusion (IR) injury (IRI). Genistein, a polyphenolic non-steroidal compound, has been extensively explored in oxidative stress, inflammation and apoptosis. Our research aims to reveal the potential role of genistein on renal IRI and its potential molecular mechanism both in vivo and in vitro. METHODS In vivo experiments, mice were pretreated with or without genistein. Renal pathological changes and function, cell proliferation, oxidative stress and apoptosis were measured. In vitro experiments, overexpression of ADORA2A and knockout of ADORA2A cells were constructed. Cells proliferation, oxidative stress and apoptosis were analyzed. RESULTS Our results in vivo showed that the renal damage induced by IR was ameliorated by genistein pretreatment. Moreover, ADORA2A was activated by genistein, along with inhibition of oxidative stress and apoptosis. The results in vitro showed that genistein pretreatment and ADORA2A overexpression reversed the increase of apoptosis and oxidative stress in NRK-52E cells induced by H/R, while the knockdown of ADORA2A partially weakened this reversal from genistein treatment. CONCLUSIONS Our results demonstrated that genistein have a protective effect against renal IRI by inhibiting oxidative stress and apoptosis via activating ADORA2A, presenting its potential use for the treatment of renal IRI.

Abstract
BACKGROUND Several TSC1/2- or MTOR -mutated eosinophilic renal tumor subsets are emerging, including eosinophilic solid and cystic renal cell carcinoma (ESC RCC), eosinophilic vacuolated tumors (EVTs) and low-grade oncocytic tumors (LOTs). "Unclassified renal tumors with TSC/MTOR mutations" ( TSC -mt RCC-NOS) do not meet the criteria for other histomolecular subtypes. Whether these tumors represent a continuum of 1 TS C/ MTOR -mutation-associated disease is unknown. DESIGN We evaluated the clinicopathologic and IHC profiles of 39 eosinophilic renal tumors with targeted DNA sequencing-confirmed TSC/MTOR mutations. Twenty-eight of these, plus 6 ChRCC, 5 RO, 5 ccRCC, 7 MiT RCC and 6 normal renal tissues, were profiled transcriptionally by RNA-seq. RESULTS The 39 cases were reclassified based on morphological and IHC features as ESC RCC (12), EVT (9), LOT, (8) and TSC -mt RCC-NOS (10). The mutation profiles demonstrated consistency; ESC RCCs (12/12) had TSC mutations, and most LOTs (7/8) had MTOR mutations. Ten TSC -mt RCC-NOSs exhibited heterogeneous morphology, arising a differential diagnosis with other renal tumors, including MiT RCC, PRCC and epithelioid PEComa. RNA sequencing-based clustering segregated ESC RCC, EVT and LOT from each other and other renal tumors, indicating expression profile-level differences. Most TSC- mt RCC-NOSs (6/7) formed a mixed cluster with ESC RCC, indicating similar expression signatures; one TSC- mt RCC-NOS with unusual biphasic morphology clustered with EVT. CONCLUSIONS We expanded the TSC/MTOR -associated eosinophilic renal tumor morphologic spectrum, identified gene mutation characteristics, and highlighted differential diagnosis challenges, especially with MiT RCC. ESC RCC, EVT, and LOT having distinct expression profiles. TSC -mt RCC-NOS may cluster with recognized TSC/MTOR -associated entities.

Abstract
Objective: To analyze the clinicopathological features of IgG4-related diseases (RD) of retroperitoneum and the urinary and male reproductive system (IgG4-RUMR). Methods: A total of 11 IgG4-RUMR cases from January 2013 to March 2021 were retrospectively collected at Peking University Third Hospital and Shandong Provincial Hospital affiliated to Shandong First Medical University. The clinicopathologic features, laboratory and imaging findings were analyzed and scored according to the 2019 ACR/EULAR classification criteria for IgG4-RD. Results: The 11 patients (male:female is 9∶2; mean age 59 years, range from 44 to 83 years) were initially admitted to the Deparment of Urology/Kidney Transplantation (10 cases) and the Department of Oncology (1 case). All patients had urogenital disorders or imaging abnormalities. Three of the 11 patients had a history of IgG4-RD such as lacrimal gland engorgement, salivary gland engorgement and IgG4-associated pancreatitis. Abnormal retroperitoneal soft tissue and hydronephrosis were found in eight cases, while epididymal and spermatic cord masses were found in one case, simple renal mass in one case, and"benign prostatic hyperplasia"in one case. In the 10 patients tested for serum IgG4, the serum IgG4 level was 0.8-14.4 g/L. Histologically, all cases showed significant lymphoplasmacytic infiltration and storiform fibrosis, and some were accompanied by obliterative phlebitis. The number of IgG4 positive plasma cells was 12-155 per high-power field, and the IgG4/IgG ratio was 15%-77%. According to the 2019 ACR/EULAR IgG4-RD classification standard 11 cases scored 20-48 points, all of which met the diagnostic criteria of IgG4-RUMR. Therapeutically, the patient with a simple renal mass underwent partial nephrectomy. The patient with prostate lesion underwent transurethral resection of prostate and was initially diagnosed as nonspecific chronic prostatitis. Later, the patient was admitted again because of salivary gland swelling, and the pathologic diagnosis was amended. The patient with epididymal and spermatic cord masses participated in a clinical trial about retroperitoneal fibrosis. The remaining eight patients received symptomatic treatment such as adhesiolysis and stent placement. All the patients were subsequently treated with glucocorticoid/immunosuppressant and symptoms relieved. Conclusions: IgG4-RUMR is uncommon. In clinical practice, information from clinical, serologic, radiologic and pathologic evaluations must be integrated. IgG4-RUMR should be considered in the differential diagnosis of urinary and male reproductive diseases. The 2019 ACR/EULAR classification criteria for IgG4-RD, while relatively complex, are objective and practical in the diagnosis of IgG4-RUMR.

Abstract
Objective: To investigate the clinicopathological characteristics and prognosis of the young patients with upper tract urothelial carcinoma (UTUC). Methods: The clinical data of 839 UTUC patients receiving radical nephroureterectomy at Peking University Third Hospital, Beijing, China from September 1999 to September 2019 were retrospectively analyzed. The patients were divided into the young (<55 years old, 107 cases) and elderly groups (≥55 years old, 732 cases). After the variables were balanced using propensity score matching, the patients were paired at a 1∶1 ratio. The clinicopathological characteristics and survival rates were compared between the two groups. Results: Compared with the elderly group, the young group had more males (P=0.047), a higher rate of smoking history (P=0.042), a higher rate of renal transplantation history (P<0.01), and fewer symptoms of hematuria (P=0.048). The 1-, 3-, and 5-year cancer specific survival (CSS) rates after surgery were 77.9%, 62.2%, 60.2% and 85.7%, 70.3%, 65.0% in the young and the elderly groups, respectively. The CSS and disease free survival (DFS) of young patients were shorter than those of elderly patients, but the difference was not significant either by subgroup analysis or propensity matching analysis (P>0.05). Young female patients had shorter CSS (P=0.034) and DFS (P=0.046) than elderly females. Perineural invasion (CSS, P=0.002; DFS, P<0.01) and extensive necrosis (CSS, P=0.041; DFS, P=0.001) were the independent risk factors of survival in young patients. Conclusions: Young UTUC patients are different from elderly ones in the frequencies of gender, smoking history, renal transplantation history, and first symptoms. Young female patients have a worse prognosis than elderly female ones. Perineural invasion and extensive necrosis could help clinicians to evaluate the prognosis of young UTUC patients.

Abstract
Objective: To evaluate the infection rate and influencing factors of hepatitis E virus (HEV) among key occupational population in Tianjin, so as to help occupational population to carry out HEV prevention and control. Methods: A combination of stratified random sampling and convenience sampling was carried out for the study in Tianjin in June 2019. The livestock and poultry-related farming workers, slaughtering workers, selling workers, doctors, farmers, seafood sellers, sewage pipeline workers as the key occupational population groups (1036 person) , and non key occupational population as the control group (200 person) , cross-sectional surveys were conducted in the groups. Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum IgG and IgM antibodies to HEV, and logistic regression model was used to analyze the influencing factors of HEV infection. Results: The positive rate of anti-HEV IgG in key occupational group was 26.45% (274/1036) , which was higher than that in control group of 14.50% (29/200) (χ(2)=13.41, P<0.01) . The occupations with the highest positive rate of anti-HEV IgG were livestock (swine) , breeding and slaughtering workers, all of which reached 33.96% (18/53) . The difference in infection rates between different occupations was statistically significant (χ(2)=22.57, P<0.01) . Multivariate logistic regression analysis showed that the longer working years, high frequency of eating out (3-5, ≥6 times/week) , drinking raw water, eating under-cooked pork or pig liver, and low frequency of washing hands were risk factors for HEV infection in occupational population (P<0.05) . But the high education is a protective factor for HEV infection (P<0.05) . Conclusion: There is a high positive rate of anti-HEV IgG in key occupational population in Tianjin. It is necessary to strengthen the monitoring, publicity and education of the high-risk population, pay attention to personal and dietary hygiene.

Abstract
The development of upper tract urothelial carcinoma (UTUC) has been associated with the ingestion of aristolochic acid (AA) in Chinese herbs. The tumors are more malignant and patients have a worse prognosis in China compared with that in Western countries. Recently, whole-genome and exome sequencing of AA-associated UTUCs found that the most frequently mutated gene was lysine demethylase 6A (KDM6A). However, its biological role and clinical significance have not yet been defined in patients with UTUC in China. A total of 108 surgically resected UTUC samples were obtained. Using immunohistochemistry, the protein expression level of KDM6A in the tumors was investigated together with the clinical and pathological characteristics of the patients, including survival times. In the present study, the expression level of KDM6A was significantly lower in UTUC specimens compared with that in samples from the normal urothelium. Lower KDM6A expression was also found to be significantly associated with a higher tumor grade and shorter cancer-specific and disease-free survival times (P=0.023 and P=0.033, respectively). In addition, using immunohistochemical analysis, no positive association was found between KDM6A expression and the expression of H3K27me3 or histone-lysine N-methyltransferase EZH2, a histone methyltransferase that generates H3K27me3. The results of the present study indicated that decreased KDM6A expression level was significantly associated with tumor grade and decreased survival time in UTUC, suggesting that KDM6A expression could be used as a prognostic marker in patients with UTUC in China.

Abstract
Our previous research demonstrated that extracellular adenosine 5'-triphosphate (ATP) could promote breast cancer cell invasion. However, the impact of extracellular ATP on chemoresistance and the mechanisms behind ATP pro-invasion and pro-chemoresistance remain unclear. Here we aimed to determine the molecules or signaling pathways involved. cDNA microarray was performed to identify the differentially expressed genes before and after ATP treatment. As a result, Sex-determining region Y-box 9 (SOX9) was up-regulated after ATP treatment in breast cancer cells. In vitro invasion and migration assays demonstrated that knocking down SOX9 attenuated ATP-driven invasive capability. Mass spectrometry and co-IP revealed that SOX9 interacted with Janus kinase 1 (JAK1). Afterward, IL-6-JAK1-STAT3 signaling was demonstrated to promote SOX9 expression and invasion following ATP treatment. Notably, ATP-IL-6-SOX9 signaling was shown to stimulate chemoresistance in breast cancer cells. ChIP assays identified some potential SOX9 target genes, among which carcinoembryonic antigen-related cell adhesion molecule 5/6 (CEACAM5/6) was demonstrated to mediate ATP pro-invasive function, while ATP-binding cassette subfamily B member 1 (ABCB1) and ATP-binding cassette subfamily G member 2 (ABCG2) mediated ATP-driven chemoresistance. In addition, SOX9-knockdown and apyrase (an ATP hydrolase)-treated MDA-MB-231 cells illustrated decreased tumor growth and enhanced drug sensitivity in nude mice. In vitro spheroid formation assays also proved the significance of ATP-SOX9 in mediating chemoresistance. Moreover, molecules involved in ATP-SOX9 signaling were up-regulated in human breast carcinoma specimens and were associated with poor prognosis. Altogether, SOX9 signaling is vital in ATP-driven invasion and chemoresistance, which may serve as a potential target for breast cancer therapies.

Abstract
Objective: To describe the epidemiological characteristics of a cluster of COVID-19 cases reported in Baodi district of Tianjin as of 18 February, 2020, which might be associated with the exposure in a local department store, and provide suggestions for prevention and control strategy development. Methods: The basic characteristics, time and area distributions, clinical manifestations, epidemiological history and transmission mode of the COVID-19 cases associated with the department store exposure were analyzed. Results: A total of 40 COVID-19 cases were associated with the department store exposure, accounting for 75.47% of the total confirmed cases (53 cases) reported in Baodi district. The cases were mainly at the age of 60 years or older (35.00%) and farmers (40.00%). The main clinical manifestations included fever (95.00%), cough (35.00%), and diarrhea (15.00%). The proportion of confirmed severe cases was 32.50%. The incidence curve showed that the incidence peak occurred on 31 January, 2020. Among the 40 cases, 6(15.00%) were department store employees, 19 (47.50%) were customers and 15 (37.50%) were close contacts (secondary cases). The first case occurred on 21 January, 2020, this case was a department store employee who had a purchasing history at whole sale markets in other provinces and cities before the onset, and 3 employees were still on duty after symptom onsets. The median of the incubation period of customer cases was 6 days, and the median of the interval between onset and medical treatment of customer cases was 7 days. Conclusion: This was a cluster epidemic of COVID-19, which might be associated with the exposure in the department store. By now, the current prevention and control measures have achieved satisfied effects.

Abstract
BACKGROUND In higher plants, inflorescence architecture is an important agronomic trait directly determining seed yield. However, little information is available on the regulatory mechanism of inflorescence development in perennial woody plants. Based on two inflorescence branching mutants, we investigated the transcriptome differences in inflorescence buds between two mutants and wild-type (WT) plants by RNA-Seq to identify the genes and regulatory networks controlling inflorescence architecture in Jatropha curcas L., a perennial woody plant belonging to Euphorbiaceae. RESULTS Two inflorescence branching mutants were identified in germplasm collection of Jatropha. The duo xiao hua (dxh) mutant has a seven-order branch inflorescence, and the gynoecy (g) mutant has a three-order branch inflorescence, while WT Jatropha has predominantly four-order branch inflorescence, occasionally the three- or five-order branch inflorescences in fields. Using weighted gene correlation network analysis (WGCNA), we identified several hub genes involved in the cytokinin metabolic pathway from modules highly associated with inflorescence phenotypes. Among them, Jatropha ADENOSINE KINASE 2 (JcADK2), ADENINE PHOSPHORIBOSYL TRANSFERASE 1 (JcAPT1), CYTOKININ OXIDASE 3 (JcCKX3), ISOPENTENYLTRANSFERASE 5 (JcIPT5), LONELY GUY 3 (JcLOG3) and JcLOG5 may participate in cytokinin metabolic pathway in Jatropha. Consistently, exogenous application of cytokinin (6-benzyladenine, 6-BA) on inflorescence buds induced high-branch inflorescence phenotype in both low-branch inflorescence mutant (g) and WT plants. These results suggested that cytokinin is an important regulator in controlling inflorescence branching in Jatropha. In addition, comparative transcriptome analysis showed that Arabidopsis homologous genes Jatropha AGAMOUS-LIKE 6 (JcAGL6), JcAGL24, FRUITFUL (JcFUL), LEAFY (JcLFY), SEPALLATAs (JcSEPs), TERMINAL FLOWER 1 (JcTFL1), and WUSCHEL-RELATED HOMEOBOX 3 (JcWOX3), were differentially expressed in inflorescence buds between dxh and g mutants and WT plants, indicating that they may participate in inflorescence development in Jatropha. The expression of JcTFL1 was downregulated, while the expression of JcLFY and JcAP1 were upregulated in inflorescences in low-branch g mutant. CONCLUSIONS Cytokinin is an important regulator in controlling inflorescence branching in Jatropha. The regulation of inflorescence architecture by the genes involved in floral development, including TFL1, LFY and AP1, may be conservative in Jatropha and Arabidopsis. Our results provide helpful information for elucidating the regulatory mechanism of inflorescence architecture in Jatropha.

Abstract
This study aims to investigate the effect of different local testicular treatments and validate common prognostic factors on primary testicular lymphoma (PTL) patients. We retrospectively reviewed the clinical records of 32 patients from 1993 to 2017 diagnosed with PTL and included 22 patients for analysis. The Kaplan–Meier method, Log-rank test, and multivariate Cox proportional hazard regression analysis were applied to evaluate progression-free survival (PFS), overall survival (OS), and determine prognosis predictors. The median follow-up time was 30 months. Median OS and PFS were 96 months and 49 months, respectively. In univariate analysis, advanced Ann Arbor stage (III/IV) (P < 0.001), B symptoms (P < 0.001), and extranodal involvement other than testis (P = 0.001) were significantly associated with shorter OS and PFS. In multivariate analysis, Ann Arbor stage was significantly associated with OS (OR = 11.58, P = 0.049), whereas B symptom was significantly associated with PFS (OR = 11.79, P = 0.049). In the 10 patients with the systemic usage of rituximab, bilateral intervention could improve median OS from 16 to 96 months (P = 0.032). The study provides preliminary evidence on bilateral intervention in testes in the rituximab era and validates common prognostic factors for Chinese PTL patients.

Abstract
Objective: To evaluate the efficacy of reinforcement on duodenal stump using single purse-string suture during laparoscopic radical gastrectomy for gastric cancer in preventing duodenal stump leakage. Methods: A descriptive cohort study was conducted to retrospectively collect clinical data of 211 patients with gastric adenocarcinoma who underwent laparoscopic radical gastrectomy with Roux-en-Y or Billroth Ⅱ reconstruction and reinforcement on duodenal stump using laparoscopic single purse-string suture in Zhongshan Hospital of Fudan University between January 2013 and December 2016. Of 211 patients, 136 were male and 75 were female with mean age of (57.5±11.1)(24 to 87) years. Tumors locating at gastric upper 1/3, middle 1/3 and low 1/3 were found in 62, 68 and 81 patients respectively. Eighty-three cases underwent total gastrectomy, 128 underwent distal subtotal gastrectomy, 107 underwent Roux-en-Y reconstruction and 104 underwent Billroth II reconstruction. The procedure of reinforcement on duodenal stump using single purse-string suture during laparoscopic radical gastrectomy was as follows: (1) after cutting the duodenal stump to about 2.0 cm in length, use a 3-0 single-strand absorbable suture to make a muscle layer purse at a distance of 1.0 to 1.5 cm from the duodenal stump; (2) use the purse line to make a slipknot; (3) push the duodenum stump into the purse with a needle holder or grasper; (4) tighten the knot of the purse string, and then make 4 to 5 knots for reinforcement. Postoperative complications were defined and graded according to the Clavien-Dindo grading criteria, and the incidence of early complications was recorded. Clinicopathologic features and postoperative outcomes were analyzed. Results: All patients completed operations successfully. The mean time of laparoscopic single purse-string suture was (5.1±1.6) (3.6 to 10.2) minutes. Postoperative early complication occurred in 31 cases (14.7%), of whom 27 cases developed surgery-related complications (12.8%), including 7 cases (3.3%) of peritoneal infection, 6 (2.8%) of pancreatic leakage, 4 (1.9%) of wound infection, 4 (1.9%) of gastroplegia, 2 (0.9%) of peritoneal hemorrhage, 2 (0.9%) of intestinal obstruction, 2 (0.9%) of lymphatic leakage, and no duodenal stump leakage; while 4 cases (1.9%) developed internal non-surgical complication, including 3 cases (1.4%) of pulmonary infection and 1 (0.5%) of cardiovascular event. The patient with peritoneal hemorrhage was healed after re-operation and all other patients were discharged uneventfully after conservative treatment. Four cases (1.9%) developed complications beyond grade III a of Clavien-Dindo criteria. Conclusion: Reinforcement on duodenal stump using laparoscopic single purse-string suture during laparoscopic radical gastrectomy with Roux-en-Y or Billroth II reconstruction is simple and effective, and can prevent the risk of development of duodenal stump leakage.

Abstract
Extracellular ATP has been shown to play an important role in invasion and the epithelial‐mesenchymal transition (EMT) process in breast cancer; however, the mechanism is unclear. Here, by using a cDNA microarray, we demonstrated that extracellular ATP could stimulate hypoxia‐inducible factor (HIF) signaling and upregulate hypoxia‐inducible factor 1/2α (HIF‐1/2α) expression. After knocking down HIF‐1/2α using siRNA, we found that ATP‐driven invasion and EMT were significantly attenuated via HIF2A‐siRNA in breast cancer cells. By using ChIP assays, we revealed that the biological function of extracellular ATP in invasion and EMT process depended on HIF‐2α direct targets, among which lysyl oxidase‐like 2 (LOXL2) and matrix metalloproteinase‐9 (MMP‐9) mediated ATP‐driven invasion, and E‐cadherin and Snail mediated ATP‐driven EMT, respectively. In addition, using silver staining and mass spectrometry, we found that phosphoglycerate kinase 1 (PGK1) could interact with HIF‐2α and mediate ATP‐driven HIF‐2α upregulation. Furthermore, we demonstrated that expressions of HIF‐2α and its target proteins could be regulated via ATP by AKT‐PGK1 pathway. Using a Balb/c mice model, we illustrated the function of HIF‐2α in promoting tumor growth and metastasis in vivo. Moreover, by exploring online databases, we found that molecules involved in ATP‐HIF‐2α signaling were highly expressed in human breast carcinoma tissues and were associated with poor prognosis. Altogether, these findings suggest that extracellular ATP could promote breast carcinoma invasion and EMT via HIF‐2α signaling, which may be a potential target for future anti–metastasis therapy.

Abstract
Currently, the main sample pretreatment methods for forensic toxic analysis are liquid-liquid extraction (LLE) and solid-phase extraction (SPE). As a simple, convenient, and low-cost LLE method, dispersion liquid-liquid microextraction (DLLME) has high enrichment factor and good extraction efficiency, and therefore has attracted the attention of many researchers in the field of toxicology analysis in recent years. As a multi-functional microextraction method, DLLME has been widely used in the analysis of pesticides, sleeping sedatives, drugs and heavy metal poisons in forensic toxic analysis. Meanwhile, it can also be used in combination with such a variety of analytical instruments as gas chromatography-electron capture detectors (GC-ECD), high performance liquid chromatography-diode array detectors (HPLC-DAD). As a sample pretreatment method, DLLME has the advantages of simple operation, less use of organic solvent, reliable results and good reproducibility, thus can meet the requirements of modern court toxic analysis.

Abstract
目的 比较评估初诊时血清游离轻链比值(rFLC)及差值(dFLC)对多发性骨髓瘤(MM)患者预后的价值。 方法 收集整理2012年1月至2016年3月有FLC检测记录的479例初治MM患者的相关临床资料,采用四分位间距法将rFLC、dFLC进行分组。将rFLC分别为3组:≤14.828、14.828~364.597、≥364.597。将dFLC分为3组:≤112.85 mg/L、112.85~2 891.83 mg/L、≥2 891.83 mg/L。随后分别对不同分组进行预后分析比较。使用Kaplan-Meier进行无进展生存(PFS)和总生存期(OS)比较,使用Cox回归进行单因素、多因素预后相关性分析。 结果 不同截断范围rFLC或dFLC患者的OS及PFS差异均有统计学意义。rFLC≤14.828组OS明显优于其他两组(未达到对61个月对47个月,P=0.019);PFS与rFLC 14.828~364.597组相比,差异无统计学意义(P=0.227),与rFLC≥364.597相比,差异有统计学意义(P=0.024)。dFLC≤112.85 mg/L组与其他两组相比PFS、OS差异均有统计学意义。单因素、多因素分析显示rFLC仅与患者OS显著相关,而dFLC与患者OS、PFS均显著相关。4年OS率比较,rFLC≤14.828组4年OS率达90.84%,明显高于其他两组(59.29%、62.26%);dFLC≤112.85 mg/L组4年OS率达89.97%,明显高于其他两组(41.32%、71.95%)(P<0.05)。 结论 对于初治MM患者,不同截断范围的rFLC、dFLC对患者生存预后影响不同。其中rFLC≤14.828或dFLC≤112.85 mg/L,其生存预后差异更为明显,且具有更低的死亡风险,危险比也更低。以此截断值判断患者预后较为理想。

Abstract
Objective: To review the experience of percutaneous catheterization for extracorporeal membrane oxygenation (ECMO) by respiratory intensivists at a single institution. Methods: A retrospective review of 87 patients undergoing percutaneous catheterization for ECMO in Department of Respiratory and Critical Care Medicine of Beijing Chaoyang Hospital from November 2009 to January 2017. Subject demographics, type of support, cannulation configuration, types of cannulas, use of imaging modalities, and complications were recorded and summarized. Results: The 87 patients consisted of 61 males and 26 females. The average age was (47±16)years (range 15-82 years ). Fifty-six patients were given ECMO therapy because of acute respiratory distress syndrome(ARDS), and 16 were treated as a bridge for lung transplantation and 15 for other causes. Eighty-one cases were given VV-ECMO support, and 6 cases were given VA-ECMO support. The most commonly used cannulas were 15-17 F arterial cannulas and 21-23 F venous cannulas. Preinsertion ultrasound was performed in 62 patients (71%) . Bedside chest radiography was used to help adjust the position of the end of the cannula in 11 patients (13%). Percutaneous catheterization was successful in 85 cases (97%) , while it failed in 2 female patients due to thick subcutaneous fat layer, and open surgical approach was used. Percutaneous femoral artery collateral circulation was established by ourselves in 5 cases. One patient with femoral artery catheterization without collateral circulation had gangrene of limbs. The complications included 9 cases of catheter site hemorrhage, 4 catheter-related bloodstream infection and 1 pulmonary embolism during ECMO weaning. Conclusion: Percutaneous catheterization for ECMO can be performed with a high rate of success and a low rate of complications.

Abstract
BACKGROUND Tumor IL17-producing (IL17A+) cells infiltration has different prognostic values among various cancers. The objective of this study was to assess the effect of IL17A+ cells in gastric cancer. PATIENTS AND METHODS The study included two patient cohorts, the Cancer Genome Atlas cohort (TCGA, n = 351) and the Zhongshan Hospital cohort (ZSHC, n = 458). The TCGA and ZSHC were used for mRNA-related and cells infiltration-related analyses, respectively. The roles of IL17A mRNA and IL17A+ cells in overall survival (OS), response to adjuvant chemotherapy (ACT), and immune contexture were evaluated. Another independent cohort was included to identify the correlation between mRNA of IL17A and IL17A+ cells infiltration (the preliminary Zhongshan Hospital cohort, PZSHC, n = 21). RESULTS The infiltration of IL17A+ cells was positively correlated with the expression of IL17A mRNA (Spearman's ρ = 0.811; P < 0.001). High IL17A mRNA expression and intratumoral IL17A+ cells were correlated with improved OS and remained to be significant after adjusted for confounders. Patients with TNM II/III disease whose tumor present higher intratumoral IL17A+ cells or lower peritumoral IL17A+ cells can benefit more from ACT. Elevated IL17A mRNA expression and increased intratumoral IL17A+ cells infiltration was associated with more antitumor mast cells and nature killer cells infiltration and less pro-tumor M2 macrophages infiltration. High IL17A mRNA expression represented a Th17 cells signature and immune response process and was correlated with increased cytotoxic GZMA, GZMB, IFNG, PRF1, and TNFSF11 expression. CONCLUSIONS IL17A mRNA expression and intratumoral IL17A+ cells infiltration were correlated with antitumor immune contexture. IL17A+ cells infiltration could be used as an independent prognostic biomarker for OS and predictive biomarker for superior response to ACT, and further prospective validation needs to be conducted.

Abstract
Objective: To investigate the clinicopathologic and differential diagnostic features of glomus tumor of the kidney. Methods: Four cases of glomus tumor of the kidney were collected from the archives of Peking University Third Hospital, the Second Hospital of Tianjin Medical University, Ningbo Yinzhou Second Hospital and Zhejiang Provincial People's Hospital between January 2012 to June 2017; the clinical and radiologic features, histomorphology, immunohistochemistry, ultrastucture and prognosis were analyzed and the relevant literature was reviewed. Results: Patients consisted of 2 men and 2 women with ages ranging from 37 years to 66 years (mean 55 years). Three patients had history of hypertensive disease (grade Ⅱ, 3 to 10 years). The tumors measured in maximum diameter from 3.0 cm to 4.0 cm (mean 3.6 cm) and showed gray-white to yellow and tan on cut surface. Macroscopical examinations showed all tumors were circumscribed but non-encapsulated. Histologically, 1 tumor presented as glomus tumor with extensive myxoid change, 1 as cellular and solid pattern glomus tumor, 1 as glomangioma with focal myopericytoma-like pattern and 1 as symplastic glomus tumor with areas resembling myopericytoma. The tumor cells in two cases showed scant cytoplasm and uniform, bland-appearing nuclei without mitoses. In one case, the tumor cells were epithelioid with abundant eosinophilic cytoplasm and relatively well-defined cell borders. There was an increased mitosis of 4/50 HPF; however, no evidence of atypical mitosis or nuclear atypia was noted. In the symplastic glomus tumor the tumor cells showed frequently nuclear pleomorphism without mitoses. By immunohistochemistry, all tumors showed strong and diffuse reactivities to at least 3 of the 4 muscle-associated markers (SMA, h-Caldesmon, MSA and Calponin), 3 tumors strongly and diffusely expressed collagen Ⅳ, 2 expressed CD34 and 1 focally expressed desmin; whereas markers including epithelial, neuroendocrine, nephrogenic, melanoma-associated, STAT6, S-100 protein, CD117 and β-catenin all were negative in all the 4 tumors. Ultrastuctural analysis was done in 2 cases and showed prominent cytoplasmic actin bundles and pericellular basement membrane, and lacking of rhomboid renin crystals in both tumors. The hypertension persisted after surgical resection for all the 3 patients with this medical history. Follow-up information (range: 6-64 months, mean: 44 months)showed that no evidence of local recurrence or distant metastasis was identified in all 4 patients. Conclusions: Glomus tumor rarely occurs in the kidney and usually has a good prognosis. Careful attention to its morphology with the judicious use of immunohistochemistry and ultrastuctural analysis can be helpful for its diagnosis and differential diagnosis.

Abstract
Objective: To investigate the histomorpholgic spectrum, immunophenotypic, and molecular genetic features of Sertoli cell tumor, not otherwise specified (SCT, NOS) of the testis. Methods: Seven cases of SCT, NOS of the testis were analyzed(4 from Peking University Third Hospital and 3 from Zhejiang Provincial People's Hospital) between 2008 and 2017. The histopathologic features were examined based on HE staining, and EnVision method was used for immunohistochemistry staining of calretinin, inhibin, β-catenin, cyclinD1, CD10, CKpan, neuroendocrine markers, WT1, Melan A, vimentin, SALL4, GATA3, PAX8, and S-100 protein. Mutational analysis of exon 3 of the CTNNB1 gene by polymerase chain reaction (PCR)-amplified sequences and direct sequencing was performed. Results: Patients ages ranged from 22 to 65 years (mean 43 years). The clinical manifestation in all was a slowly enlarging, painless testicular mass.The maximum diameter of the tumor ranged from 1.5 cm to 3.0 cm (mean 2.1 cm). Sectioning usually disclosed a tan-gray to white mass with vague lobular cut-surface. Microscopically, the tumors were well circumscribed and non-encapsulated; the tumor cells were rearranged in multiple growth patterns from diffuse solid sheets to trabeculae and cords, ribbon and solid or hollow tubules setting in variable amount of acellular fibrous stroma. Two cases showed acellular collagenous stroma constituted >50% of the tumor confirming to the diagnosis of sclerosing SCT. One case demonstrated a prominent myxoid stromal change. The tumor cells typically had moderate amounts of pale to lightly eosinophilic cytoplasm, 2 tumors had variable cells with abundant lipid-rich cytoplasm, and 1 other tumor showed scattered aggregates of multinucleated tumor cells. The tumor cells were bland-appearing without any evidence of atypia, mitoses were noted in 2 tumors (both were 1/50 HPF), but necrosis was absent. Immunohistochemical staining results as follows: vimentin (diffuse, 7/7), CD10 (diffuse membrane, 7/7); diffuse β-catenin nuclear and cytoplasm staining in 5 of 7 cases, and all the 5 cases showed diffuse cyclin D1 nuclear staining, β-catenin membrane staining in 2 of 7 cases, CKpan (5/7, focal or diffuse), calretinin (focal, 5/6), inhibin (focal, 3/7), synaptophysin (focal, 2/6), CD56 (focal or diffuse, 4/5), WT1 (diffuse nuclear, 4/5), and S-100 protein (diffuse, 3/7), and chromogranin A, Melan A, PAX8, GATA3 and SALL4 all were negative. Molecular genetic studies of PCR and direct sequencing showed CTNNB1 mutations in 4 of 7 (4/7) cases, 4 of the four mutation-carrying cases showed diffuse β-catenin nuclear and cytoplasm immunoreactivity and diffuse cyclin D1 nuclear immunoreactivity in the tumor cells. Conclusions: SCT, NOS of the testis typically shows significant heterogeneities in both morphology and immunohistochemistry, thus causing differential diagnostic confusions. Molecular analyses showed mutations of exon 3 of CTNNB1 in more than half of these tumors, and nuclear accumulation of β-catenin and over expression of cyclin D1 can be useful for the differential diagnosis of SCT, NOS.

Abstract
To evaluate and compare left and right testicular tissue histopathology and Johnsen score, and to investigate the necessity for bilateral testicular biopsy. We recruited180 patients with non-obstructiveazoospermia (NOA) on testicular biopsy who had undergonetesticular sperm aspiration (TESA). Pathological sections of testicular tissue were diagnosed by specially-assigned doctors, who evaluated pathological findings, determined the Johnsen score and confirmed for the presence or absence of sperm. Sperm positive rates for left and right testicular histopathology were 55.0% and 51.7% respectively, and the proportion of Johnsen scores≥8 for left and right testes were 53.3% and 50.0%, respectively. Cohen kappa values revealed that the identification of sperm in bilateral testicular samples was not consistent and was related to random effects; Optimized cut-off value for bilateral testicular volume was 11ml (Johnsen score ≥8), and optimized cut-off values of E2 on left and right testes were 144.5pmol/L and 133.5 pmol/L (Johnsen score≤7). However, age, serum prolactin (PRL), follicle stimulating hormone (FSH), luteinizing hormone (LH) and total testosterone (TT) levels were not accurate predictors for the existence of testicular sperm. There was nostatistical significance between left and right testicular histopathology in terms of sperm positive rates or Johnsen score; the Johnsen score were caused entirely by random effects and a score from one side could not represent the other side. Therefore, we recommend that both testes need to undergo surgery when NOA patients undergo testicular biopsy or sperm retrieval.

Abstract
Objective: To investigate the prevalence of hepatitis C in Tianjin, China and major risk factors, and to provide a theoretical basis for the development of scientific prevention and control strategies for hepatitis C. Methods: The monitoring system of notifiable infectious diseases was used to establish the database of hepatitis C cases reported from 2004 to 2014 in Tianjin. With reference to the results of serological surveillance and special case-control investigation, a statistical analysis was performed to investigate the epidemiological characteristics and prevalence of hepatitis C in Tianjin, as well as related risk factors. Results: The report rate of hepatitis C in Tianjin showed a decreasing trend from 2004 to 2014(χ 2 = 150.018, P < 0.01). The group aged 60 years had the highest report rate(9.09/100000), and there were significant differences between this group and other groups(χ 2 = 2540.887, P < 0.01). The six urban districts in Tianjin had the highest report rate(6.54/100000), and there were significant differences between this area and other areas. The multivariate logistic regression analysis showed that a history of surgery(χ 2 = 12.57, P < 0.01), blood transfusion and blood products(χ 2 = 36.67, P < 0.01), hemodialysis(χ 2 = 4.62, P < 0.01), and intravenous drug use(χ 2 = 12.92, P < 0.01)were major risk factors for hepatitis C. Conclusion: The epidemic situation of hepatitis C in Tianjin tends to decrease in recent years. Although there is no effective vaccine for hepatitis C, it still can be prevented and treated. The most effective interventions for hepatitis C include strengthening health education and raising the awareness rate of hepatitis C in the whole population, as well as early detection, diagnosis, and treatment.

Abstract
Objective: To evaluate the short-term and long-term outcomes after laparoscopic surgery compared with traditional laparotomy in cases of stage ⅠA2-ⅡA2 cervical cancer. Methods: We conducted a retrospective study on the clinical data of 1 863 patients diagnosed as FIGO stages ⅠA2-ⅡA2 cervical cancer in 6 third-grade class-A hospitals in Guangxi province between January 2007 and May 2014. One thousand and seventy-one received laparoscopy, and 792 received laparotomy. T-test, U-test and χ(2) test were used to compare the short-term and long-term outcomes. The short-term outcomes included surgical related outcomes and operative complications, and the long-term outcomes included quality of life (pelvic floor functions and sexual functions), survival and recurrence. Pelvic floor function and sexual function were assessed with the International Consultation on Incontinence Quesonnaire Female Lower Urinary tract(ICIQ-FLUTS) and the Female Sexual Function Inventory (FSFI), respectively. Survival rates were estimated by Kaplan-Meier analysis. The survival curves were compared with Log-rank test. Cox regression analysis was used to evaluaterisk factors for prognosis. Results: (1)The short-term outcomes : There were significant difference in operative time([(257±69) vs(238±56)min], estimated blood loss[(358±314) vs(707±431)ml], anus exhausting time[(2.5±0.9) vs (2.9±0.8)d], preserved days of catheter[(15±7) vs(18±9)d], and post-operative length of stay[(19±16) vs (30±21)d] between the laparoscopic surgery group and the opensurgery group(P<0.05). There was no significant difference in lymph nodes yielded[(21±9) vs (21±11)], left parametrial width[(2.5±0.8) vs (2.7±0.7)cm], right parametrial width [(2.6±0.3) vs (2.7±0.2)cm], vaginal cuff length[(2.4±0.7) vs (2.2±0.7)cm] between the laparoscopic surgery group and the opensurgery group(P>0.05). The intra-operative complications occurred in 8.1%(87/1 071)in the laparoscopic surgery group and in 10.7%(85/792)in the open surgery group(P>0.05). However, the complications of vascular injury in the laparoscopic surgery group[2.6%(28/1 071)]was lower than that in the open surgery group[7.7%(61/792), P<0.001]. The laparoscopic surgery exhibited lower post- operative complication rate [33.8%(362/1 071)vs 40.2%(318/792), P<0.05] and poorer wound healing rate [0.7%(7/1 071)vs 4.0%(32/792), P<0.05]. (2)The long-term outcomes(Hierarchical analysis): The overall incontinence in ICIQ-FLUTS questionnaire in nerve-sparing laparoscopic group [28.4%(67/236)] was lower than that in the open surgery group [35.9%(71/198), P=0.004] . However, There was no significant difference in degree of incontinence between the two groups(P>0.05). The overall sexual dysfunction in FSFI questionnaire after 12 months of postoperative in the nerve-sparing laparoscopic group [47.0%(111/236)]was lower than that in the open surgery group [58.6%(116/198), P=0.001], and the six different dimension scores in the laparoscopic surgery group were higher than that in the open surgery group (P<0.05). The recurrence rate was 3.5%(35/1 007)in the laparoscopicsurgery group and 4.7%(35/740)in the open surgery group(P>0.05). The 5-year OS was 94.0% for the laparoscopic surgery group and 90.2% for the open surgery group(P>0.05), and the 5-year DFS was 93.9% for the laparoscopic surgery group and 89.1% for the open surgery group(P>0.05). (3) Prognostic fators: In univariate analysis, tumor dimension, clinical stage, deep stromal invasion, LVSI, and retroperitoneal lymph node metastasis signficantly affected 5-year OS and 5-year DFS(P<0.05); In multivariate analyses, LVSI, deep stromal invasion and LN metastasis were independent prognostic factors(P<0.05). Conclusions: Laparoscopy can reduceestimated blood loss, accelerate postoperative recovery and improve the quality of life after surgery compared to laparotomy, and it ensures the same oncological results as open surgery. Laparoscopic approach is a safe and effective treatment for early-stage cervical cancer.

Abstract
CodYst is a global transcriptional regulator that modulates the metabolic network in Streptococcus thermophilus ST2017. In this study, experimental data showed that the cell survival of the codYst defective mutant obviously declined at the presence of 10 mM H2O2, suggesting CodYst was involved in response to the oxidative stress. To investigate this phenomenon, transcriptome analysis and real time-quantitative PCR were performed and the results indicated that the transcriptional level of a bifunctional glutathione synthetase gene (gshF) was downregulated by about 3-fold in the codYst defective mutant, along with a decrease by 20% of the glutathione yield compared with the wild-type in minimal chemical defined medium, whereas half of the viable cells remained after H2O2 challenge. In vitro gel shift assays showed that the purified CodYst could bind to the promoter region of gshF, with a conserved CodYst box, confirming the regulation of CodYst on the gshF gene. To our knowledge, this is first report of CodYst in response to oxidative stress mediated by the regulation of gshF in S. thermophilus.

Abstract
OBJECTIVE To investigate the predictive values of different critical scoring systems for mortality in patients with severe acute respiratory failure (ARF) supported by venovenous extracorporeal membrane oxygenation (VV-ECMO). METHODS Forty-two patients with severe ARF supported by VV-ECMO were enrolled from November 2009 to July 2015.There were 25 males and 17 females. The mean age was (44±18) years (rang 18-69 years). Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ, Ⅲ, Ⅳ, Simplified Acute Physiology Score Ⅱ (SAPS) Ⅱ, Sequential Organ Failure Assessment (SOFA), ECMO net, PRedicting dEath for SEvere ARDS on VVECMO (PRESERVE), and Respiratory ECMO Survival Prediction (RESP) scores were collected within 6 hours before VV-ECMO support. The patients were divided into the survivors group (n=17) and the nonsurvivors group (n=25) by survival at 180 d after receiving VV-ECMO. The patient clinical characteristics and aforementioned scoring systems were compared between groups. Scoring systems for predicting prognosis were assessed using the area under the receiver-operating characteristic (ROC) curve. The Kaplan-Meier method was used to draw the surviving curve, and the survival of the patients was analyzed by the Log-rank test. The risk factors were assessed for prognosis by multiple logistic regression analysis. RESULTS (1) Positive end expiratory pressure (PEEP) 6 hours prior to VV-ECMO support in the survivors group [(9.7±5.0)cmH2O, (1 cmH2O=0.098 kPa)] was lower than that in the nonsurvivors group [(13.2±5.4)cmH2O, t=-2.134, P=0.039]. VV-ECMO combination with continuous renal replacement therapy(CRRT) in the nonsurvivors group (32%) was used more than in the survivors group (6%, χ(2)=4.100, P=0.043). Duration of VV-ECMO support in the nonsurvivors group [(15±13) d] was longer than that in the survivors group [(12±11)d, t=-2.123, P=0.041]. APACHE Ⅱ, APACHE Ⅲ, APACHE Ⅳ, ECMO net, PRESERVE, and RESP scores in the survivors group were superior to the nonsurvivors group (all P<0.05). (2) The areas under the ROC curve of APACHE Ⅳ score for predicting death were largest (0.792±0.076, 95%CI: 0.643-0.940, P<0.05). The best cutoff point was 48 for APACHE Ⅳ score with a sensitivity of 92.0%, specificity of 64.7%, and overall accuracy of 81%. (3) Kaplan-Meier survival analysis showed that 180 d survival rate of the low APACHE Ⅳ score group was higher than the high APACHE Ⅳ score group (χ(2)=11.331, P<0.05). (4) Multiple logistic regression analysis showed that PEEP (OR=1.555, 95%CI: 1.097-2.204, P<0.05), APACHE Ⅳ score (OR=1.152, 95%CI: 1.021-1.301, P<0.05), and PRESERVE score (OR=4.984, 95%CI: 1.531-16.227, P<0.05) were independent risk factors associated with mortality of patients supported by VV-ECMO. CONCLUSION The critical scoring systems proved to have good prognostic ability in predicting hospital mortality for severe ARF patients supported by VV-ECMO. Compared to other scoring systems, APACHE Ⅳ score system predicted more accurately, while specific scoring systems in predicting hospital mortality showed no advantage.

Abstract
Objective: To observe the clinicopathologic features and prognosis of prostate cancer (PCa) in young men. Methods: Twenty-eight early onset (≤55 years) patients with PCa pathologically confirmed in the Peking University Third Hospital and Peking University Shougang Hospital from January 1st 2000 to August 31st 2016 were collected. There were 18 radical prostatectomy (RP) cases and 10 transrectal prostatic biopsy cases. Contemporaneously, 445 elderly (>55 years) patients were collected, of which 385 had detailed pathological information, were chosen as control group. The mean age of young group was 51 years (29-55 years). Follow-up data for 22 cases were available (1-110 months). The correlation of the clinicopathological features and prognosis were analyzed retrospectively. Results: Presurgical prostatic specific antigen (PSA) level was abnormal in young patients, with 18 cases (64.3%) had elevated fPSA level, 26 (92.9%) had increased tPSA level, and 26 (92.9%) had decreased fPSA/tPSA ratio. Gleason score (GS) was 8 in 10.7% (3/28) of cases, and 9 in 42.9% (12/28) of cases. Of the 18 patients with RP, 17 (94.4%) had pT stage ≥pT2c. PSA level (P=0.006) and GS (P=0.001) were positively correlated with pT stage. Family history of PCa in 1st degree relatives was found in 9.1% of the cases. During follow-up, 2 patients died of PCa, 7 patients showed progression within 24 months. There were no significant differences in PSA level and GS between young patients and elderly patients, while the former group was more likely to have incontinence (P=0.023), higher PSA levels (P=0.001), and lower overall survival (P=0.049). Only postsurgical PSA level was found to be negatively associated with overall survival (P=0.030) and cancer specific survival (P=0.021) in young patients. Conclusions: Presurgical PSA level and GS are positively correlated with pT stage of early onset PCa. Compared with elderly patients, young patients are more likely to have incontinence, higher postsurgical PSA level, and lower overall survival. Among all the parameters, only postsurgical PSA level shows an adverse impact on prognosis of early onset PCa. Young patients, especially those with family history, may benefit from studies on the susceptibility loci and phenotype of PCa.

Abstract
Inter-simple sequence repeats (ISSRs) were used to analyze the genetic diversity of 21 accessions obtained from four provinces in China, Shandong, Henan, Hebei, and Sichuan. A total of 272 scored bands were generated using the eight primers previously screened across 21 accessions, of which 267 were polymorphic (98.16%). Genetic similarity coefficients varied from 0.4816 to 0.9118, with an average of 0.6337. The UPGMA dendrogram grouped 21 accessions into two main clusters. Cluster A comprised four Lonicera macranthoides Hand. Mazz. accessions, of which J10 was found to be from Sichuan, and J17, J18, and J19 were found to be from Shandong. Cluster B comprised 17 Lonicera japonica Thumb. accessions, divided into the wild accession J16 and the other 16 cultivars. The results of the principal component analysis were comparable to the cluster analysis. Therefore, the ISSR markers could be effectively used to distinguish interspecific and intraspecific variations, which may facilitate identification of Lonicera japonica cultivars for planting, medicinal use, and germplasm conservation.

Abstract
The accumulation of H at the small-angle tilt grain boundary (GB) in the W(001) surface is investigated, on the basis of the first-principles calculations. By exploring the solution and diffusion behaviors of H at the GB, we find that the small-angle GB can capture the H atoms nearby, serving as a nucleation site of H bubbles. With the increasing number of trapped H atoms, the GB expands gradually, and the GBs can be unripped with an areal density of H up to 5.0 × 1015 H atoms per cm2, leading to the formation of H bubbles. Moreover, H2 molecules are observed, when the areal density of H atoms in GB is over 6.6 × 1015 atoms per cm2. According to our calculations, we propose a possible formation mechanism of H bubbles observed in the experiment, which is valuable for improving the service performance of W as a plasma-facing material in nuclear fusion reactors.

Abstract
Objective: To evaluate the epidemiology, clinicopathological features and prognosis in upper tract urothelial carcinoma (UTUC) patients. Methods: All archival 368 UTUC cases that underwent radical nephroureterectomy between September 1999 and October 2014 were reviewed, and their clinicopathological features were analyzed. Follow-up time was 1-216 months, with a mean follow-up of 41 month. Results: One hundred and twenty-eight male and 240 female patients were included, with a mean age of 68 years ranging from 31 to 88 years. Tumor locations were classified in detail as follows: 148 renal pelvic tumors, 155 ureteral tumors, 58 renal pelvic and ureteral tumors, and 7 transitional tumors. Patients with history of renal transplantation (14.7%, 54/368) were more likely to develop UTUC before the age of 65 (P<0.01), with bilateral tract involved (P<0.01) and multifocal distributed (P=0.004). Histological grade was significantly associated with T stage (P<0.01), lympho-vascular involvement (P=0.001), neural invasion (P=0.005), carcinoma in situ (P=0.001) and extensive necrosis (P=0.020), while high-grade UTUC predominantly occurred in female patients (P=0.010) and histological variants (P<0.01). T stage was positively correlated with tumor size (P<0.01), lympho-vascular involvement (P<0.01), neural invasion (P<0.01) and lymph node metastasis (P=0.001). Furthermore, among the 214 followed-up cases, 76 died of the disease. Histological grade (P=0.002, P=0.005), T stage (P<0.01, P<0.01), lympho-vascular involvement (P=0.001, P=0.008), neural invasion (P<0.01, P=0.001) and extensive necrosis (P=0.017, P=0.023) were significantly associated with shorter overall survival and cancer specific survival of UTUC patients, respectively. In multivariable analyses, T stage (P<0.01, P<0.01) and extensive necrosis (P=0.004, P=0.014) were independent predictive factors of both overall survival and cancer specific survival, while neural invasion (P=0.007) and lymph node metastasis (P=0.007) were independent predictors of the overall survival. Conclusions: Chinese UTUC reveals its unique epidemiology. UTUC more commonly occurs in women and has a similar incidence between the renal pelvic and ureteral carcinoma. Patients with history of renal transplantation are prone to detect UTUC through physical examination rather than hematuria. Histological grade, T stage, lympho-vascular involvement, neural invasion and extensive necrosis are predictors of survival in UTUC patients, while advanced-stage and extensive necrosis are independent predictors of poor outcome.

Abstract
A global search for the stable structures of bilayer Ge (BLG) is performed, and the most stable and meta-stable BLG structures are predicted for the first time. Phonon-spectrum calculations and ab initio molecular dynamics simulations confirm their dynamical and thermal stability. The computed electronic structures suggest that the most stable structure is metal while the meta-stable structure of BLG is a semiconductor with an indirect band gap (0.32 eV at the level of PBE functional and 0.81 eV at the level of HSE06). By straining the layer plane of the meta-stable BLG, we observe a phase transition from semiconductor to metal. Furthermore, the adsorption of gas molecules of CO, CO2, NH3, NO and NO2 on the meta-stable structure is also studied. Our results show that the predicted meta-stable BLG also possesses a good feature in gas sensors.
