Abstract
Objective: To investigate the effect and safety of transnasal humidified rapid insufflation ventilatory exchange (THRIVE) technique in hysteroscopic diagnostic and therapeutic surgery. Methods: This study was a randomized controlled trial. A total of 100 female patients undergoing hysteroscopy surgery at Beijing Tongren Hospital from September to December 2023 were selected and randomly divided into two groups by the random number table method: the THRIVE group and the mask oxygen group, with 50 patients in each group. Patients in both groups were given total intravenous anesthesia with propofol combined with remifentanil and preserved spontaneous respiration. The THRIVE group was given oxygen by the THRIVE device with an oxygen flow rate of 50 L/min, while the mask oxygen group was given oxygen by the mask with an oxygen flow rate of 5 L/min; the oxygen concentration of both groups was set at 100%. The general condition of the patients, vital signs during the operation, the amount of anesthesia drugs used and the operation time were recorded. The primary observation index was the incidence of hypoxic events in the two groups; the secondary observation indexes were the incidence and time of intraoperative apnea as well as the corresponding oxygenation interventions and the incidence of non-hypoxic adverse events. Results: The age of the THRIVE group was (42±14) years, and the age of the mask oxygen group was (43±15) years. The duration of surgery in the THRIVE group was (15.9±3.4) min, which was statistically lower than that of the mask oxygen group (16.3±4.5) min (P=0.041), and there were no differences observed in the duration of awakening time and anesthesia time (both P>0.05). There was no significant difference in the dosage of propofol, remifentanil, and intraoperative vasoactive drugs between the two groups (all P>0.05). The SpO2 of the patients in the THRIVE group at the end of the operation was (99.7±1.1) %, which was higher than that of the mask-oxygen group (99.1±1.1) % (P<0.05). There was no difference in SpO2 of the two groups at the other time points (all P>0.05). There were no differences in HR and MAP of two group patients at each time point (all P>0.05). The incidence of hypoxic events in the THRIVE group was 12.0% (6/50), which was lower than that of 28.0% (14/50) in the mask oxygen group (P=0.045). The difference in the incidence and duration of apnea between the two groups was not statistically significant (all P>0.05). There were no cases of temporary need for laryngeal mask or tracheal intubation during surgery in both groups. There was no statistically significant difference in the incidence of intraoperative body movement, dizziness, nausea and vomiting between the two groups (all P>0.05), and no cardiac, cerebral, renal or other important organ insufficiency occurred in the two weeks after surgery. Conclusion: THRIVE technology can provide effective oxygenation for patients undergoing hysteroscopic diagnosis and treatment, maintain patients' circulatory stability, and improve the safety and efficiency of surgery.

Abstract
INTRODUCTION To determine effects of adjuvant chemotherapy (AC) on survival outcomes compared to surgery alone without AC for upper tract urothelial carcinoma (UTUC) patients with variant histology (VH). METHODS We conducted a systematic review and meta-analysis of studies investigating AC for UTUC in Medline, Embase, the Cochrane library up to January 2023. Population, intervention, comparator, and outcome were UTUC patients with VH, radical nephroureterectomy with AC, radical nephroureterectomy only, and oncological survival, respectively. RESULTS Four retrospective studies were included. Regarding overall survival (OS), the pooled hazard ratio was 0.61 (95% confidence interval: 0.42-0.87; p = 0.007) across two studies. Regarding cancer specific survival (CSS), the pooled hazard ratio was 0.46 (95% confidence interval: 0.25-0.84; p = 0.01) across three studies. All included studies had a high quality based on the Newcastle-Ottawa Scale. Certainty of evidence for OS was low. Certainty of evidence for CSS was moderate due to a strong association (hazard ratio < 0.5). Publication bias was not significant for any studies. CONCLUSION In UTUC patients with VH, administration of AC after surgery might have better survival outcomes than surgery alone. Our study provides evidence for decision-making of clinicians who treat UTUC patients with VH.

Abstract
PURPOSE To conduct systematic review and meta-analysis to evaluate effects of neoadjuvant chemotherapy (NAC) on survival and histopathological outcomes of variant histology (VH) of urothelial carcinoma (UC) of bladder. METHODS This systematic review was registered in PROSPERO (CRD42023389115). Literature search was conducted in PubMed/Medline, Embase, and Cochrane Library for studies published up to January 2023. Population, intervention, comparator, outcome, and study design were as follows: bladder cancer patients with VH (population), neoadjuvant chemotherapy (intervention), radical cystectomy only (comparators), oncological survival and pathologic response (outcomes), and retrospective or prospective (study design). RESULTS Finally, a total of 17 studies were included in the present study (quantitative analysis, n = 17; qualitative analysis, n = 12). Pooled HR was 0.49 (95% CI: 0.31-0.76; P = .002) for OS. Pooled HR was 0.61 (95% CI: 0.38-0.98; P = .04) for CSS. Pooled HR was 0.44 (95% CI: 0.21-0.93; P = .03) in PFS. Pooled OR was 6.61 (95% CI: 4.50-9.73; P < .00001) in complete pathologic response. Pooled OR was 9.59 (95% CI: 3.56-25.85; P < .00001) in any pathologic response. Evidence quality assessments for each 5 comparisons using the GRADE approach were that Certainty was moderate in 1, low in 1, and very low in 3. CONCLUSIONS Administration of NAC before surgery in bladder cancer patients with VH might confer better survival outcomes and higher pathologic down staging rate than no administration of NAC before surgery.

Abstract
Objective: To explore the relationship between liver iron deposition and steatosis in patients with non-alcoholic fatty liver disease (NAFLD) through MRI. Methods: 163 cases of liver biopsy underwent MRI examination. R2* was used to measure liver iron content. Dixon-based proton density fat fraction (PDFF) was used to measure liver fat content. One-way ANOVA, r-correlation, ROC curve, and others were used to assess the relationship between clinical case data, serological indices, and imaging results in accordance with the pathological results of the liver biopsy. Results: R2* gradually increased as the pathological steatosis grade rose. The R2* that corresponded to no steatosis (< 5%), mild steatosis (14.95%±8.55%), moderate steatosis (46.30%±9.32%), and severe steatosis (73.86%±6.35%) were 27.56±4.40, 31.06±5.95, 38.06±4.80, and 48.10±5.55 (P < 0.001), respectively. There was a positive correlation between R2* and liver steatosis content (r= 0.769, P < 0.05). The area under the ROC curve and cut-off value were 0.88 and 31.77, respectively, and there was no distinct relationship with liver inflammation or fibrosis. Conclusion: R2* can quantitatively and non-invasively evaluate liver iron deposition in patients with NAFLD. A distinct relationship exists between liver steatosis and iron deposition, and iron deposition tends to increase as the steatosis aggravates.

Abstract
BACKGROUND Recent studies have shown that donor nephrectomy can induce renal function impairment. However, few meta-analysis studies about this have proceeded. Therefore, the objective of this systematic review and meta-analysis including all data of recent research studies was to determine whether living donor nephrectomy (LDN) could induce renal function impairment. METHODS By November 2020, comprehensive literature searches were performed on PubMed, Embase, and Cochrane databases. Inclusion criteria were: (1) observational studies with data about overall end-stage renal disease (ESRD) or chronic kidney disease (CKD) of living kidney donors, (2) control group consisted of people without donor nephrectomy, and (3) outcomes of studies included long-term end-stage renal disease risks after living kidney donation. Risk of Bias in Non-randomized Studies of interventions (ROBINS-I) assessment tool was used to evaluate our methodological quality. RESULTS The qualitative review included 11 studies and the meta-analysis included 5 studies. In the meta-analysis, the integrated overall ESRD risk was 5.57 (95% CI: 2.03-15.30). Regarding the overall risk of bias using ROBINS-I assessment tool, 0 studies was rated as "Low", 7 studies were rated as "moderate", 2 studies were rated as "Serious", and two studies were rated as "Critical". CONCLUSIONS Our study showed that LDN increased ESRD risk in LDN patients. However, in our meta-analysis, variables in included studies were not uniform and the number of included studies was small. To have a definite conclusion, meta-analyses of well-planned and detailed studies need to be conducted in the future.

Abstract
PURPOSE Cardiovascular disease (CVD) is one of the leading causes of death, accounting for one-third of all deaths worldwide. Patients with CVD are three times more likely to complain of sexual dysfunction than healthy people. Causes of sexual dysfunction in patients with CVD include physical/mental changes and drug side effects. The prevalence of sexual dysfunction in patients with CVD has been estimated to be up to 89%. Ordinary treatments such as pharmacotherapy cannot effectively reduce sexual problems. Therefore, sexual rehabilitation has a broad spectrum, including exercise therapy such as pelvic floor muscle treatment, appropriate counseling, a multidisciplinary approach, and partner rehabilitation. In this study, systematic review and meta-analysis was performed to investigate the effect of sexual rehabilitation on sexual problems in patients with CVD. MATERIALS AND METHODS Comprehensive literature searches were conducted using MEDLINE, Cochrane Library electronic database, and EMBASE through June 2022. Questionnaire scores at the end point as outcomes of the study were recorded as were standardized mean difference (SMD) with their 95% confidence intervals (CIs). Meta-regression analysis was conducted for each moderator. We performed a risk of bias evaluation for included studies using the RoB 2 tool. RESULTS The overall SMD in the meta-analysis for sexual rehabilitation versus no-sexual rehabilitation was 0.430 (95% CI, 0.226-0.633). There was a statistical difference between groups. SMD changes were 0.674 (95% CI, 0.308-1.039) at one month and 0.320 (95% CI, 0.074-0.565) at six months. The regression analysis with all variables (number of patients, study duration, and questionnaire types) revealed no significance. CONCLUSIONS This study indicates that sexual rehabilitation is an effective method with high therapeutic potential for sexual dysfunction of patients with CVD. However, for clinical application, well-designed studies with many patients should be conducted in the future and the standardization of rehabilitation protocols is required.

Abstract
BACKGROUND Because of limited differentiation to endothelium from mesenchymal stem cells, it has been strongly recommended to use endothelial progenitor cells for the regeneration of the damaged endothelium of corpora cavernosa. This study was performed to investigate the immortalized human cerebral endothelial cells and their capability for repairing erectile dysfunction in a rat model of cavernous nerve injury. Circulating endothelial progenitor cells were isolated from human fetal brain vasculature at the periventricular region of telencephalic tissues. Over 95% of CD 31-positive cells were sorted and cultured for 10 days. Human cerebral endothelial progenitor cells were injected into the cavernosa of rats with cavernous nerve injury. Erectile response was then assessed. In in vivo assays, rats were divided into three groups: group 1, sham operation: group 2, bilateral cavernous nerve injury: and group 3, treatment with human cerebral endothelial cells after cavernous nerve injury. RESULTS Established immortalized circulating endothelial progenitor cells showed expression of human telomerase reverse transcriptase transcript by RT-PCR. They also showed the expression of vascular endothelial growth factor, von Willebrand factor, vascular endothelial growth factor receptor, and CD31, cell type-specific markers for endothelial cells by RT-PCR. In in vitro angiogenesis assays, they demonstrated tube formation that suggested morphological properties of endothelial progenitor cells. In in vivo assays, impaired erectile function of rat with cavernous nerve injury recovered at 2, 4, and 12 weeks after transplantation of human cerebral endothelial cells into the cavernosa. CONCLUSIONS Telomerase reverse transcriptase-circulating endothelial progenitor cells from fetal brain vasculature could repair erectile dysfunction of rats with cavernous nerve injury.

Abstract
BACKGROUND Several cohort studies have explored the relationship between androgen deprivation therapy (ADT) and the severity of coronavirus disease 2019 (COVID-19). This study aimed to characterize the relationship between ADT and the severity of COVID-19 in patients with prostate cancer. METHODS A systematic search was conducted using PubMed, Embase, and Cochrane Library databases from the inception of each database until February 31, 2020. Patients with prostate cancer who were treated with ADT were assigned to treatment group while those patients who were not treated with ADT were assigned to the control group. Outcomes were severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) positivity, hospitalization, intensive care unit (ICU) admission, and death. The risk of bias was evaluated using ROBINS-I (Risk Of Bias In Non-randomized Studies of Interventions) tool. RESULTS Three studies with qualitative synthesis were included. Finally, two studies with quantitative synthesis having a total of 44,213 patients were included for the present systematic review. There was no significant difference in SARS-CoV-2 positive rate (odds ratio [OR], 0.52; 95% confidence intervals [Cis], 0.13-2.09; P = 0.362), hospitalization (OR, 0.52; 95% CIs, 0.07-3.69; P = 0.514), ICU admission (OR, 0.93; 95% CIs, 0.39-2.23, P = 0.881), or death (OR, 0.88; 95% CIs, 0.06-12.06; P = 0.934) between ADT and non-ADT groups. CONCLUSION Qualitative and quantitative analyses of previous studies revealed no significant effect of ADT on COVID-19. However, more studies with higher quality that explore biochemical and immunological factors involved are needed to confirm this finding in the future.

Abstract
Objective: To analyze the survival and influencing factors of HIV infections and AIDS cases (HIV/AIDS) aged 15 years and over who had received antiretroviral treatment (ART) for more than 10 years in Henan Province. Methods: In this retrospective cohort study, data of HIV infections and AIDS cases in Henan province were collected from the AIDS Prevention and Control System between January 1, 2002 and December 31, 2020. This study included 20 256 participants alive after 10-year ART with complete baseline and follow-up information, such as demographic characteristics, CD4+T lymphocyte count and viral load. Cox proportional risk regression model was used to analyze influencing factors of HIV/AIDS survival. Results: A total of 20 256 participants were followed up for 82 738.2 person-years, with an average follow-up of 4.1 person-years, of which most cases were blood transmission (85.5%) and married (71.2%). The male to female ratio was 1∶1.06 and the age at 10 years of ART was (51.2±8.7) years old. About 88.5% of HIV/AIDS patients received ART in village/township treatment institutions. Overall, there were 2 030 deaths during this period, among which 1 897 were due to AIDS-related diseases (93.5%) and the case fatality rate was 9.4% (1 897/20 256). Cox proportional risk regression model showed that participants aged 40-54, 55-69, and ≥70 years had a higher risk of death compared to those aged 25-39, with adjusted HRs (95%CI) of 1.57 (1.19-2.08), 3.78 (2.86-4.99), and 6.17 (4.33-8.79), respectively. Participants with the initial CD4+T lymphocyte count about 200-349/μl and<200/μl had a higher risk of death compared to those with initial CD4+T lymphocyte count ≥350/μl, with adjusted HRs (95%CI) of 1.81 (1.61-2.04) and 3.64 (3.20-4.15), respectively. Participants with the initial viral load outcome ≥1 000 copies/ml had a higher risk of death compared to those with the initial viral load outcome<1 000 copies/ml, with adjusted HRs (95%CI) of 1.73 (1.52-1.97). Participants receiving the second-line ART had a lower risk of death compared to those receiving the first-line ART, with adjusted HRs (95%CI) of 0.12 (0.11-0.14). Conclusion: From 2002 to 2020, the survival rate of HIV/AIDS treated with ART for more than 10 years is high in Henan Province. Age, CD4+T lymphocyte count and viral load are influencing factors of HIV/AIDS survival.

Abstract
Purpose This study aimed to evaluate benign prostatic hyperplasia (BPH) diagnosis rate and the changing landscape of medical and surgical management of BPH over the last decade using national population data of South Korea. Methods The present study analyzed data of patients diagnosed with BPH (N40) who underwent medical treatment or surgery in 3% of the national patient sample of the Health Insurance and Review Assessment database each year between 2012 and 2018. The primary outcome was the proportion of medical and surgical treatment for BPH. It was evaluated each year between 2012 and 2018. Secondary outcomes included total BPH diagnosis rate in each year of the study period. BPH diagnosis rate by age group was evaluated. The proportion of medical and surgical treatment for BPH according to the type of medical institution was investigated. Results The proportion of surgical treatment was 1.2% in 2012, 1.0% in 2013, 1.0% in 2014, 0.9% in 2015, 0.8% in 2016, 0.7% 2018, and 0.8% 2018, showing a progressive overall decrease from 2012 to 2018. The rate of surgical treatment for BPH increased with increasing age during the study period, showing a progressive overall increase (from 9,202 per 100,000 men in 2012 to 11,610 per 100 000 men in 2018). The number of patients with BPH was increased steadily from 2012 to 2018 in all age groups. The rate of surgical treatment in tertiary referral hospitals was the highest during the study period, followed by that in general hospitals, hospitals, and clinics. Conclusions In Korea, the diagnosis rate of BPH was steadily increasing during the study period. Overall surgical treatment gradually decreased compared with an increase in medical treatment among all treatments for BPH. Thus, a comprehensive treatment plan for BPH should be established considering this trend.

Abstract
Objective: To analyze the correlation between serum ferritin and steatosis in non-alcoholic fatty liver disease. Methods: Data of 167 cases who underwent liver biopsy in the Affiliated Hospital of Hangzhou Normal University were collected. Hydrogen proton magnetic resonance spectroscopy were performed within one week. The pathological results of liver biopsy were used as the gold standard to analyze the case data, serological indicators, magnetic resonance spectroscopy-proton density fat fraction. Results: Pathological monitoring result showed that the serum ferritin in patients without steatosis, and with mild, moderate and severe steatosis were (206.20 ± 189.83), (286.65 ± 200.80), (326.55 ± 214.71), (391.50 ± 184.93) ng/ml, respectively, P < 0.005. Serum ferritin was correlated to body mass index, PDFF, alanine aminotransferase, gamma glutamyltransferase, low-density lipoprotein, high-density lipoprotein. The area under the receiver operating characteristic curve with ferritin for the diagnosis of non-alcoholic fatty liver disease was 0.716, and the optimal diagnostic threshold was 214.56 ng/ml. The sensitivity and specificity were 80.1%, and 68.8%, respectively. There was no statistically significant difference between the intralobular inflammation, fibrosis, and ferritin. Prussian blue iron staining had no apparent deposition of iron particles. Conclusion: Ferritin has significant positive correlation with the results of pathological and magnetic resonance imaging for liver steatosis. Therefore, it can be used as a non-invasive diagnostic method for liver steatosis evaluation.

Abstract
Objective: To analyze the mortality in HIV/AIDS cases aged ≥15 years under antiretroviral treatment (ART) in Henan province from 2002 to 2019, and provide evidence for reducing the mortality rate of HIV/AIDS and AIDS prevention and treatment. Methods: Data of HIV/AIDS cases aged ≥15 years who received ART in Henan from 2002 to 2019 were obtained from "Infectious Disease Surveillance System - Basic Information on AIDS Prevention and Control". In this retrospective study, Cox proportional risk model was used to analyze the influencing factors for HIV/AIDS related deaths. Software SPSS 23.0 was used for statistical analysis. Results: From 2002 to 2019, a total of 72 986 HIV/AIDS cases aged ≥15 years received ART, in whom, 16 634 died during this period. Most of the death cases were aged ≥40 years old (68.5%,11 393/16 634), males (62.6%,10 419/16 634), infected through blood-borne transmission (71.7%,11 927/16 634), and farmers or migrant workers (91.7%,15 249/16 634). Most of the deaths were due to AIDS related diseases (73.7%, 12 261/16 634), and the case fatality rate was 16.8% (12 261/72 986). A total of 34.6% (4 237/12 261) of HIV/AIDS cases died of AIDS-related diseases in the first year of ART, and the cumulative survival rates at 10 and 18 years of ART were 78.3% and 71.8%, respectively. The proportion of the HIV/AIDS cases with baseline CD4+T lymphocyte (CD4) counts <200 cells/μl at age 15 years when ART started was 45.5% (30 432/66 898). Cox proportional risk regression model showed that, compared with the cases with baseline CD4 counts ≥350 cells/μl, the risk of death was 1.78 times higher than in the cases with CD4 counts <200 cells/μl (95%CI: 1.64-1.94) and 1.24 times higher in the cases with CD4 counts ≥200 cells/μl (95%CI: 1.13-1.36), respectively. The risk of death in symptomatic cases at baseline survey was 1.25 times higher than that in asymptomatic cases (95%CI: 1.16-1.35). The cases with a latest viral load ≥1 000 copies/ml had 7.09 times higher risk of death than those with a last viral load<1 000 copies/ml (95%CI: 6.65-7.54). Conclusions: The majority of HIV/AIDS deaths occurred in the cases aged ≥15 years receiving ART in Henan province during 2002-2019, who were infected through blood-borne transmission and farmers/migrant workers, and AIDS-related diseases were the main causes of the deaths. With the gradual implementation of ART policy, the high survival rate in HIV/AIDS cases can be maintained for a long time in Henan. To reduce the case fatality rate and improve the quality of life of HIV/AIDS patients, CD4 counts test should be further strengthened and eligible HIV/AIDS patients should be covered by standard ART in a timely manner.

Abstract
Study question
Is ERA testing different between RIF patients with control group?
Summary answer
In RIF patients, there were more chances of non-receptive endometrium. ERA testing may be helpful for the patients with repeated IVF failure. What is known already: The endometrium receptivity analysis testing might have the ability to detect the implantation window. In repeat implantation failure patients, detecting of precisely implantation window may have some benefits.
Study design, size, duration
This was a single-center retrospective observational study. Two hundred and forty-nine patients who underwent ERA testing following frozen-thawed embryo transfer in our center were including in this study between January 2019 and May 2020.
Participants/materials, setting, methods
181 patients having unexplained repeated IVF failure (RIF group, at least tow implantation failure) and 68 patients having no experience with embryo transfer (Control group) who underwent ERA testing were including in this study. Both of Patients having a receptive (R) ERA and having a non-receptive (NR) ERA underwent a personalized embryo transfer (pET) on ERA. ERA results and clinical outcomes compared between RIF group and control group were analyzed by Chi-square test.
Main results and the role of chance
The proportion of R/NR results were 33:35 for the RIF group and 118:63 for the Control group, demonstrating the displacement of the window of implantation in patients with RIF. Our results revealed an endometrial factor in 51% RIF patients, which was significantly greater than the Control group 34.8% (P = 0.02). Among the patients with NR ERA result, there are not significantly difference in clinical pregnancy rate in the RIF group compared with control group (57.1%. vs. 61.9%). The clinical pregnancy rate of the patients with receptive ERA result also is comparable in both group (70.3% vs. 66.7%).
Limitations, reasons for caution
This is a retrospective, single center study with limited case number. There were may some bias with ERA testing errors.
Wider implications of the findings: In RIF patients, there were more chances of non-receptive endometrium. ERA testing may be helpful for the patients with repeated IVF failure. Larger randomized studies are required to validate these results.

Abstract
STUDY QUESTION What is the transcriptome signature associated with poor performance of rescue IVM (rIVM) oocytes and how can we rejuvenate them? SUMMARY ANSWER The GATA-1/CREB1/WNT signalling axis was repressed in rIVM oocytes, particularly those of poor quality; restoration of this axis may produce more usable rIVM oocytes. WHAT IS KNOWN ALREADY rIVM aims to produce mature oocytes (MII) for IVF through IVM of immature oocytes collected from stimulated ovaries. It is not popular due to limited success rate in infertility treatment. Genetic aberrations, cellular stress and the absence of cumulus cell support in oocytes could account for the failure of rIVM. STUDY DESIGN, SIZE, DURATION We applied single-cell RNA sequencing (scRNA-seq) to capture the transcriptomes of human in vivo oocytes (IVO) (n = 10) from 7 donors and rIVM oocytes (n = 10) from 10 donors. The effects of maternal age and ovarian responses on rIVM oocyte transcriptomes were also studied. In parallel, we studied the effect of gallic acid on the maturation rate of mouse oocytes cultured in IVM medium with (n = 84) and without (n = 85) gallic acid. PARTICIPANTS/MATERIALS, SETTING, METHODS Human oocytes were collected from donors aged 28-41 years with a body mass index of <30. RNA extraction, cDNA generation, library construction and sequencing were performed in one preparation. scRNA-seq data were then processed and analysed. Selected genes in the rIVM versus IVO comparison were validated by quantitative real-time PCR. For the gallic acid study, we collected immature oocytes from 5-month-old mice and studied the effect of 10-μM gallic acid on their maturation rate. MAIN RESULTS AND THE ROLE OF CHANCE The transcriptome profiles of rIVM/IVO oocytes showed distinctive differences. A total of 1559 differentially expressed genes (DEGs, genes with at least 2-fold change and adjusted P < 0.05) were found to be enriched in metabolic processes, biosynthesis and oxidative phosphorylation. Among these DEGs, we identified a repression of WNT/β-catenin signalling in rIVM when compared with IVO oocytes. We found that oestradiol levels exhibited a significant age-independent correlation with the IVO mature oocyte ratio (MII ratio) for each donor. rIVM oocytes from women with a high MII ratio were found to have over-represented cellular processes such as anti-apoptosis. To further identify targets that contribute to the poor clinical outcomes of rIVM, we compared oocytes collected from young donors with a high MII ratio with oocytes from donors of advanced maternal age and lower MII ratio, and revealed that CREB1 is an important regulator. Thus, our study identified that GATA-1/CREB1/WNT signalling was repressed in both rIVM oocytes versus IVO oocytes and in rIVM oocytes of lower versus higher quality. Consequently we investigated gallic acid, as a potential antioxidant substrate in human rIVM medium, and found that it increased the mouse oocyte maturation rate by 31.1%. LARGE SCALE DATA Raw data from this study can be accessed through GSE158539. LIMITATIONS, REASONS FOR CAUTION In the rIVM oocytes of the high- and low-quality comparison, the number of samples was limited after data filtering with stringent selection criteria. For the oocyte stage identification, we were unable to predict the presence of oocyte spindle, so polar body extrusion was the only indicator. WIDER IMPLICATIONS OF THE FINDINGS This study showed that GATA-1/CREB1/WNT signalling was repressed in rIVM oocytes compared with IVO oocytes and was further downregulated in low-quality rIVM oocytes, providing us the foundation of subsequent follow-up research on human oocytes and raising safety concerns about the clinical use of rescued oocytes.

The subjects were divided into the UACR normal group (<30 mg/g), microalbuminuria group (30-300 mg/g) and macroalbuminuria group (>300 mg/g). Patients with normal UACR were further divided into two groups according to the estimated glomerular filtration rate (eGFR): the eGFR low group (<90 ml·min-1·1.73m-2) and the normal eGFR group (≥90 ml·min-1·1.73m-2). Urine RBP and β2-MG levels among the groups were compared. Multiple linear regression analyses were applied to evaluate risk factors of urine RBP and β2-MG. Results: In all patients (n=1 030), urine RBP and β2-MG increased gradually with the increase of UACR across the three groups, the proportions of abnormal urine RBP (>0.7 mg/L) and β2-MG (>370 μg/L) in these groups were 3.8%, 8.5%, 39.0% (P<0.001), and 12.9%, 26.7%, 46.8% (P<0.001), respectively. In the UACR normal group (n=788), 12.2% of the patients were with eGFR<90 ml·min-1·1.73m-2. The proportion of abnormal β2-MG (>370 μg/L) was higher in the eGFR low group than that in the eGFR normal group (29.2% vs. 10.7%, P<0.001). Multivariate linear stepwise regression analyses were performed using natural logarithm of urine RBP or β2-MG as dependent variable, and showed that urine RBP was independently associated with UACR (β=0.0005, P<0.001), serum creatinine (β=0.006, P<0.001) and glycosylated hemoglobin A1c (β=0.050, P=0.001), and β2-MG was independently correlated with UACR (β=0.000 4, P<0.001), serum creatinine (β=0.011, P<0.001), systolic blood pressure (β=0.005, P=0.031) and fasting blood-glucose (β=0.027, P=0.046). Conclusions: Urine RBP and β2-MG are positively associated with high UACR and impaired renal function in T2DM patients, and these changes could occur before UACR and eGFR turned out to be abnormal. It is recommended that urine RBP and β2-MG be detected as early as possible to identify diabetic kidney disease in patients with normal UACR and eGFR.

Abstract
Introduction Although several studies have been conducted to evaluate the feasibility of Raman spectroscopy (RS) for the diagnosis of bladder cancer (BCa), it is difficult to use RS in real clinical settings based on the current limited evidence. Therefore, we performed a systematic review and meta-analysis to assess the diagnostic accuracy of RS in BCa. Materials and Methods Comprehensive literature searches were performed in the PubMed/Medline, Embase, and Cochrane Library databases up to March 2019. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, this study included reports according to the participant, intervention, comparator, outcomes, and study design approach. The methodological quality of the included studies was evaluated according to questionnaires and criteria suggested by the Quality Assessment of Diagnostic Accuracy Studies-2 tool. The quantitative outcomes included diagnostic accuracy (sensitivity and specificity). Results Fifteen studies were included for qualitative analysis and four studies (BCa cases, n = 139; control cases n = 107) were included in this analysis by screening the full text of the remaining articles based on the inclusion and exclusion criteria through a systematic review. The pooled sensitivity and specificity of RS were 0.91 (95% confidence interval [CI]: 0.85-0.95) and 0.93 (95% CI: 0.86-0.97), respectively. The among-study heterogeneity was statistically significant in the specificity results (Cochran Q statistic, P = 0.015; I2 statistic, 71.3%) but not in the sensitivity results (Cochran Q statistic, P = 0.189; I2 statistic, 37.2%). Conclusions RS showed the potential to be an efficient tool with high accuracy for detecting malignant bladder lesions. More studies with in vivo real-time settings are warranted to validate our results.

Abstract
Purpose Postoperative anemia is associated with increased morbidity and mortality in patients undergoing surgery. Anemia is also a common feature during sepsis. Therefore, here, we aimed to investigate the safety and efficacy of intravenous iron isomaltoside 1000 (Monofer®) in patients undergoing elective urologic surgery and in those with urosepsis. Materials and Methods This multicenter study was conducted through the review of the medical records of patients with postoperative anemia undergoing elective urologic surgery or with urosepsis in a multicenter hospital. Patients received a single intravenous iron isomaltoside (IIM), and their hemoglobin (Hb) level was evaluated before and after administration of IIM. Safety data included adverse effects and hypersensitivity reactions. In addition, the patients were divided into three groups (200 mg, 400 mg, and 600 mg IIM) to compare Hb changes before and after the administration of IIM. Results The study analyzed 52 men and 30 women with a mean age of 67 years. There was a significant difference between pre-treatment Hb and post-treatment Hb according to the type of the surgery after administration (p=0.01) of IIM in patients with postoperative anemia, and the mean preoperative Hb before IIM administration was 8.5 g/dL and that after IIM administration was 9.9 g/dL (p=0.006) in patients with urosepsis. The mean preoperative Hb changed from 10 g/dL to 11 g/dL after administration (p<0.001) of IIM in the whole cohort. There were no side effects due to the administration of intravenous IIM. Conclusion A single perioperative intravenous injection of IIM 1000 significantly increased the Hb level in patients with anemia who underwent urologic elective surgery. Moreover, this treatment can be considered to have potential clinical benefits for anemia caused by sepsis.

Abstract
PURPOSE We investigated whether ADT use was associated with the risk of ischemic cardiovascular diseases (CVD) and cerebrovascular diseases (CrVD) in a nationwide population-based cohort. METHODS Claims data of the Health Insurance and Review Assessment system in South Korea were used. In total, 195,308 men with newly diagnosed prostate cancer between January 1, 2008 and December 31, 2017 were identified. After applying the exclusion criteria, 131,189 men were enrolled. The study cohort was divided into ADT and non-ADT groups. Study outcomes were newly developed CVD, cardiovascular intervention (CVI), and CrVD. To control for potential confounders, various cardiovascular risk factors were balanced between groups. Cox proportional hazard regression models were used to estimate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of events. RESULTS Univariable analysis revealed that ADT was significantly associated with an increased risk of CVD and CrVD. Multivariable analysis did not reveal this association. In the propensity score matched cohort (n = 61,722), multivariable analysis demonstrated that ADT independently reduced the risk of CVD (HR 0.890; 95% CI 0.846-0.936; p < 0.0001), CVI (HR 0.873; 95% CI 0.770-0.991; p = 0.0352), and CrVD (HR 0.869; 95% CI 0.824-0.917; p < 0.0001). CVD risk was significantly decreased in patients using ADT for over 2 years. CVI and CrVD risks were significantly lower in men using ADT for over 3 years. CONCLUSION This study demonstrated that ADT may reduce the risk of CVD, CVI, and CrVD, and ADT duration is associated with this risk reduction.

Abstract
PURPOSE Prostate cancer (PCa) incidence is affected by aging phenomenon and performance of screening test. In United States, PCa incidence is affected by period effect of U.S. Preventive Services Task Force (USPSTF) recommendation. However, no study has reported the effect of USPSTF recommendation or aging phenomenon on PCa incidence in South Korea. Thus, the objective of this study was to investigate effects of age, period, and birth cohort on PCa incidence using age-period-cohort analysis. Materials and Methods Annual report of cancer statistics between 2003 and 2013 from National Health Insurance Service (NHIS) in South Korea for the number of PCa patients and Korean Statistical Information Service (KOSIS) data between 2003 and 2013 from national statistics in South Korea for the number of Korean male population were used. Age-period-cohort models were used to investigate effects of age, period, and birth cohort on PCa incidence. RESULTS Overall PCa incidence in South Korea was increased 8.8% in annual percentage (95% confidential interval, 6.5 to 11.2; p < 0.001). It showed an increasing pattern from 2003 to 2011 but a decreasing pattern from 2011 to 2013. Age increased the risk of PCa incidence. However, the speed of increase was slower with increasing age. PCa incidence was increased 1.4 times in 2008 compared to that in 2003 or 2013. Regarding cohort effect, the risk of PCa incidence started to increase from 1958 cohort. CONCLUSION PCa incidence was affected by period of specific year. There was a positive cohort effect on PCa incidence associated with age structural change.

Abstract
Objective: To understand the major high risk behaviors and related factors among reported HIV/AIDS cases aged ≥60 years in some areas of Henan province. Methods: In Dengzhou, Xunxian county of Hebi and Xiangcheng county of Xuchang, where the reported number and proportion of HIV/AIDS cases aged ≥60 years were high, a face to face interview was conducted among the cases aged ≥60 years during July-August in 2016. The information about the high risk behaviors before HIV infection confirmation were collected by using a semi-structured questionnaire. Results: A total of 33 HIV/AIDS cases aged ≥60 years were interviewed, including 28 males and 5 females. Their average age was 67.4 years. The infection route was sexual contact. The main findings revealed that the main factor for HIV infection in elder males was commercial heterosexual behavior with local female sex workers. The condom use rate was low. The poor awareness of the knowledge about AIDS prevention could explain why the elderly could not recognize the risk of HIV infection. There were also homosexual and bisexual behaviors in elder male HIV/AIDS patients. Late detection of HIV transmission among couples was the main cause of HIV infection in elder women. Conclusions: The major epidemiological related factors for HIV infection in the elderly in some areas of Henan were unsafe sex behavior and the poor awareness of knowledge about AIDS prevention. A targeted strategy should be taken to control the spread of HIV in the elderly.

Abstract
Objective: To investigate the role of neutrophil elastase inhibitor, sivelestat, in preventing and treating nonalcoholic steatohepatitis (NASH) and its underling mechanisms. Methods: A total of forty 4-week-old male C57BL/6J ApoE-/-mice were equally divided into the following four groups: standard chow (SC)+isotonic saline; SC+sivelestat; high-fat, high-cholesterol (HFHC) diet+isotonic saline; and HFHC+sivelestat. These mice were treated with above methods for 12 weeks. Blood and liver tissue samples were collected to measure biochemical parameters, hepatic steatosis and non-alcoholic fatty liver disease (NAFLD) activity score (inflammation) were evaluated by oil red O staining and HE staining, respectively. The mRNA and protein expression levels of hepatic inflammatory cytokines, CD68, and F4/80 were determined by quantitative RT-PCR and immunohistochemistry, respectively. Comparison of means between the four groups was made by one-way analysis of variance, and comparison between any two groups was made by the LSD or SNK method (for data with homogeneity of variance) or the Tamhane or Dunnett method (for data with heterogeneity of variance). Results: Mice fed with an HFHC diet for 12 weeks developed typical pathological features of NASH compared with those fed with SC. Compared with mice fed with HFHC diet without sivelestat, those treated with HFHC and sivelestat exhibited the following features: (1) significantly reduced fast blood glucose, blood cholesterol, and hepatic biochemical parameters, as well as increased insulin sensitivity; (2) significantly reduced NAFLD activity score (5.71±1.11 vs 3.16±1.16, P < 0.05); (3) reduced monocyte chemoattractant protein-1 and tumor necrosis factor -α; (4) significantly reduced mRNA levels of CD68 and F4/80; and (5) reduced expression of CD68 in the liver. Conclusion: Sivelestat alleviates the hepatic steatosis and inflammation of NASH in mice by inhibiting the activation of Kupffer cells.

Abstract
PURPOSE Radical prostatectomy (RP) is one of main treatments for prostate cancer (Pca). The prevalence of Pca has been decreasing in recent reports. However, no study has reported trends in Pca prevalence or RP rate according to age structural changes. The objective of this study was to investigate trends in Pca prevalence and frequency of RP according to age structural change. MATERIALS AND METHODS We evaluated trends in Pca prevalence and RP rate using National Health Insurance Data from 2005 to 2015. Relationships for Pca prevalence and RP rate with age structural change were also determined. Primary outcomes included trends in Pca prevalence and RP rates according to age groups, comparing those before and after 2011. RESULTS Pca prevalence tended to increase before 2011 and decreased after 2011 in persons in the 60-years age group. RP rate increased pattern before 2011 and decreased after 2011 in age groups of 50s, 60s, and over 70s. Pca prevalence and age structural change showed a significantly positive relationship in all age groups, except for the age group under 40 years. RP rate and age structural change also showed a significantly positive relationship in all age groups. CONCLUSION Age structural change can affect the decreasing trend in Pca prevalence and RP rate in South Korea. Future studies are needed to validate this result.

Abstract
Objective: To assess the association and intensity of baseline TC level with the incidence of lung cancer in men in China. Methods: Since May 2006, all the male workers, including the employees and the retirees in Kailuan Group were recruited in the Kailuan male dynamic cohort study. Information about demographics, medical history, anthropometry and TC level were collected at the baseline interview, as well as the information of newly-diagnosed lung cancer cases during the follow-up period. According to guidelines for blood lipids in Chinese adults and the distribution in the population, TC level was classified into five groups as followed: <160, 160-, 180-, 200- and ≥240 mg/dl, with the second quintile group (160- mg/dl) serving as the referent category. Cox proportional hazards regression model and restricted cubic spline (RCS) model were used to evaluate the association and the nonlinear association between baseline TC level and the risk of lung cancer in the men. Results: By December 31, 2014, for the 109 884 men, a follow up of 763 819.25 person-years was made with a median follow-up period of 7.88 years. During the follow up, 808 lung cancer cases were identified. After adjustment for age, education level, income level, smoking status, alcohol consumption level, history of dust exposure, FPG level and BMI, HR (95%CI) of lung cancer for men with lower TC level (<160 mg/dl) and higher TC level (≥240 mg/dl) were 1.34 (1.04- 1.72) and 1.45 (1.09-1.92), respectively, compared with men with normal TC level (160- mg/dl). The results didn't change significantly after exclusion of newly diagnosed cancer cases within 2 years of follow up and subjects with the history of hyperlipidemia. Conclusion: Our results showed that TC might be associated with higher risk of lung cancer. Men with lower TC level or higher TC level had higher risk for lung cancer. Keep moderate TC level might be one of the effective precaution for the prevention of lung cancer.

Abstract
OBJECTIVE To investigate the efficacy and safety of noninvasive intravesical instillation of onabotulinum toxin-A (OBTX-A) through systematic review and meta-analysis. Recently, several studies of noninvasive intravesical instillation of OBTX-A have been published. However, its efficacy is not well validated yet compared to well-known efficacy of minimally invasive intravesical injection of OBTX-A. METHOD Systematic review and meta-analysis were performed to evaluate the efficacy of noninvasive intravesical instillation of OBTX-A in patients with overactive bladder and interstitial cystitis/bladder pain syndrome by measuring outcomes such as urgency episode per 72 hours, frequency per 72 hours, urgency urinary incontinence, voided volume (VV), postvoided residual volume, maximum flow rate, and patient perception of bladder condition. RESULT Six trials in 4 studies that compared instillation of OBTX-A and placebo involving 248 patients (121 experimental and 127 controls) were included for final data extraction. Instillation of OBTX-A significantly increased VV, with a mean difference of 38.48 (95% confidence interval: 76.05, 0.92) compared to the placebo group. However, other outcomes showed statistically insignificant changes. Major adverse events were not reported in the group receiving intravesical instillation of OBTX-A. CONCLUSION Intravesical instillation of OBTX-A showed limited efficacy with improvement of VV for treatment of overactive bladder or interstitial cystitis/bladder pain syndrome. More studies are needed to overcome the efficacy of current noninvasive bladder instillation of OBTX-A regarding effective drug transport.

Abstract
OBJECTIVES To investigate the association between lower urinary tract symptoms (LUTS) and cardiovascular disease (CVD) risk in women, as severe LUTS are known to be associated with CVD risk in men but few studies have focused on this issue in women. SUBJECTS AND METHODS A total of 1014 ostensibly healthy women, who participated in a voluntary health check in a health promotion centre from November 2013 to October 2015, were enrolled. LUTS were assessed using the International Prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS). CVD risk scores were calculated using the Framingham risk score and the American College of Cardiology/American Heart Association Atherosclerotic Cardiovascular Disease (ASCVD) score. Correlation, partial correlation, and multiple logistic regression analyses were conducted. RESULTS The mean age and body mass index (BMI) of the women were 51 years and 22.6 kg/m2 , respectively. The ASCVD score showed significant positive correlations with IPSS items Question 2 (Q2), Q3, Q5, and Q7 (all P < 0.05), total IPSS (P = 0.001), IPSS storage (P = 0.006) and IPSS voiding symptoms scores (P = 0.001) based on partial correlation analysis after adjustment for BMI. For the OABSS, the ASCVD score showed significant positive correlations with OABSS items Q2, Q3, and Q4 (P < 0.001, P = 0.017, and P < 0.001, respectively) and total OABSS (P < 0.001). Multiple logistic regression analysis showed that the moderate-severe risk groups of the OABSS and IPSS were associated with the ASCVD risk score in adjusted models (P < 0.001) compared to the none-mild OABSS and mild IPSS groups. After adjustment for age and BMI, IPSS storage score was significantly related with the ASCVD risk score (B = 0.855, P = 0.016) CONCLUSIONS: LUTS, especially storage symptoms, might be risk factors for predicting future CVD risk in women. Further prospective or cohort studies are needed to validate this possibility.

Abstract
Objective: To investigate whether elevated levels of high sensitivity C-Reactive Protein (hsCRP) and neutrophil (NE) at baseline are associated with an increased risk of colorectal cancer in Kailuan male cohort. Methods: Since May 2006, males from Kailuan cohort were included in this study. Information on demographics, medical history, anthropometry, hsCRP and NE were collectedat baseline for all subjects. Multivariable Cox proportional hazards regression models were used to calculate hazard ratios (HR) of association between baseline hsCRP and NE and colorectal cancer risk. Results: By December 31, 2015, a total of 73 869 participants were enrolled in this study. During the follow-up, 336 incident colorectal cancer cases were identified. All participants were divided into three groups according to the level of hsCRP (<1 mg/L, 1-3 mg/L and >3 mg/L). The cumulative incidence of colorectal cancer were 456/10(5,) 510/10(5) and 746/10(5) in these 3 groups, respectively (χ(2)=10.79, P=0.005). Compared with participants with lower hsCRP levels (<1 mg/L), individuals with the highest hsCRP (>3 mg/L) levels had significant increased risks of colorectal cancer (HR=1.38, 95%CI: 1.05-1.81, P=0.020)after adjusting for age, gender, smoking, drinking, BMI, diabetes and income. Furthermore, subjects were divided into two groups according to the level of NE (≤ 4.08×10(9)/L and > 4.08×10(9)/L). Multivariable Cox proportional hazards regression models indicated that there is no statistical significance of association between NE and colorectal cancer. Conclusions: Elevated levels of hsCRP at baseline might increase the risk of colorectal cancer in males.

Abstract
OBJECTIVE To study the survival effect of AIDS patients after the antiretroviral treatment that initiated at different times and to understand the factors associated with the survival time. METHODS Information on AIDS patients who started receiving the antiretroviral therapy during 2002-2014 was collected from the Chinese HIV/AIDS Integrated Control System in Henan province. According to the level of baseline immunology, all the participants were divided into earlier treatment group [Baseline CD4(+)T lymphocyte cell counts (CD4) between 350/μl and 500/μl] or conventional treatment group (Baseline CD4 cell counts≤350/μl). Data was analyzed with both Survival and Review methods. RESULTS A total number of 37 169 cases were selected, including 32 129 cases in the conventional treatment group and 5 040 cases in the earlier treatment group. Mortalities in the conventional treatment group and earlier treatment group were 4.3/100 person year and 1.8/100 person year, respectively. Data on the 11-year cumulative survival rate of both the conventional treatment group and earlier treatment group were 67.9% and 82.3%, respectively. By means of multi-variable analysis, we found that factors as gender, age, marital status, route of infection, number of symptoms, missed taking drugs in the past 7 days, degree of education at baseline of conventional treatment group etc. were associated with survival time of patients after the initiation of antiretroviral treatment (ART) (P<0.05) while factors as gender, age, marital status, ever missed taking drugs in the past 7 days at baseline etc. in the earlier treatment group were associated with the survival time of patients after the ART initiation (P<0.05). CONCLUSION Strategy including earlier initiation of antiretroviral treatment on AIDS patients who had met the treatment criteria and programs related to the improvement on adherence to medication, could prolong the survival time of AIDS patients, in Henan province.

Abstract
OBJECTIVE To understand the hepatitis C virus infection status and related risk factors in drug users in Henan province during 2011-2015 and provide scientific evidence for the development of HCV infection prevention and control measures. METHODS Cross-sectional questionnaire surveys were conducted among the drug users and blood samples were taken from them for HCV antibody detection during HIV sentinel surveillance period in Henan province from April to June during 2011-2015. RESULTS The HCV infection rate in drug users increased from 3.70% in 2011 to 6.54% in 2015 (trend χ(2)=25.93, P<0.01). Multivariate analysis indicated that HCV infection related risk factors included age older (OR=1.23, 95% CI: 1.13-1.35, P=0.00), place of domicile (OR=3.45, 95%CI: 2.59-4.60, P=0.00), traditional drug user or mixed drug user (OR=1.46, 95%CI: 1.10-1.93, P=0.01; OR=1.82, 95%CI: 1.18-2.81, P=0.01), injecting drug user (OR=2.88, 95%CI: 2.45-3.39, P=0.00), commercial sex behavior in recent one year (OR=1.44, 95%CI: 1.20-1.72, P=0.00) and drug user in compulsory drug rehabilitation or those receiving methadone maintenance treatment (OR=1.79, 95% CI: 1.28-2.50, P=0.00; OR=1.74, 95% CI: 1.17-2.58, P=0.01). CONCLUSION The HCV infection rate in drug users was higher in Henan and increased rapidly with years. In order to control HCV spread, it is necessary to strengthen the management of drug users and take effective intervention measures.

Abstract
OBJECTIVE To investigate the quality of life and its related factors among HIV/AIDS patients from HIV serodiscordant couples in Zhoukou city of Henan province. METHODS During January to May in 2015, by the convenience sample, World Health Organization Quality of Life Questionnaire for Brief Version (WHOQOL-BREF) (Chinese version) and a self-edited questionnaire were used to investigate 1 251 HIV/AIDS patients who were confirmed with HIV positive by local CDC, registered in"HIV serodiscordant family" and agreed to participate in a face-to-face interview with above 18 year-old based on the local CDC , township hospitals and village clinics of 9 counties and 1 district of Zhoukou city, excluding the HIV/AIDS patients who were in divorce, death by one side, unknowing about his HIV status, with mental illness and disturbance of consciousness, incorrectly understanding the content of the questionnaire, and reluctant to participate in this study. The scores of quality of life of physical, psychological, social relations, and environmental domain were calculated. The related factors of the scores of different domains were analyzed by Multiple Two Classification Unconditioned Logistic Regression. RESULTS The scores of investigation objects in the physical, psychological, social relations, and environmental domain were 12.00± 2.02, 12.07 ± 2.07, 11.87 ± 1.99, and 11.09 ± 1.84, respectively. The multiple Unconditioned Logistic Regression analysis indicated that age <40 years, on ART and no other sickness in last two weeks were beneficial factors associated with physical domain with OR (95%CI): 0.61 (0.35-1.06), 0.52 (0.30-0.90), and 1.66 (1.09-2.52), respectively. The possibility of no poverty and no other sickness in last two weeks increased to 0.15(0.09-0.26) and 1.57(1.06-2.33) times of those who was in poverty and with other sickness in last two weeks in physical domain. The possibility of participants who were below 40 years old and with children increased to 0.58 (0.34-0.98) and 0.37 (0.23-0.57) times of who were above 40 years old and without children in psychological domain. The factors of with AIDS related symptoms, no children and with other sickness in last two week were found to be significantly associated with environmental domain with OR (95%CI): 0.65 (0.48-0.88), 0.66 (0.51-0.85), and 0.65 (0.51-0.84), respectively .

Abstract
BACKGROUND There is still controversy as to whether initial combination treatment is superior to serial addition of anticholinergics after maintenance or induction of alpha blockers in benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS). OBJECTIVE The objective of this study was to determine the benefits and safety of initial combination treatment of an alpha blocker with anticholinergic medication in BPH/LUTS through a systematic review and meta-analysis. METHODS We conducted a meta-analysis of improvement in LUTS using International Prostate Symptom Score (IPSS), maximal urinary flow rate (Qmax), post-voided residual volume (PVR), and quality of life (QoL). RESULTS In total, 16 studies were included in our analysis, with a total sample size of 3,548 subjects (2,195 experimental subjects and 1,353 controls). The mean change in total IPSS improvement from baseline in the combination group versus the alpha blocker monotherapy group was -0.03 (95% CI: -0.14-0.08). The pooled overall SMD change of storage IPSS improvement from baseline was -0.28 (95% CI: -0.40 - -0.17). The pooled overall SMD changes of QoL, Qmax, and PVR were -0.29 (95% CI: -0.50 - -0.07), 0.00 (95% CI: -0.08-0.08), and 0.56 (95% CI: 0.23-0.89), respectively. There was no significant difference in the number of acute urinary retention (AUR) events or PVR. CONCLUSIONS Initial combination treatment of an alpha blocker with anticholinergic medication is efficacious for in BPH/ LUTS with improved measures such as storage symptoms and QoL without causing significant deterioration of voiding function.

Abstract
Chinese Fusion Engineering Test Reactor (CFETR) is a new superconducting tokamak device being designed in China, which aims at bridging the gap between ITER and DEMO, where DEMO is a tokamak demonstration fusion reactor. Two diagnostic cases, ITER-like case and towards DEMO case, have been considered for CFETR early and later operating phases, respectively. In this paper, some preliminary consideration of ITER-like case will be presented. Based on ITER diagnostic system, three versions of increased complexity and coverage of the ITER-like case diagnostic system have been developed with different goals and functions. Version A aims only machine protection and basic control. Both of version B and version C are mainly for machine protection, basic and advanced control, but version C has an increased level of redundancy necessary for improved measurements capability. The performance of these versions and needed R&D work are outlined.

Abstract
BACKGROUND The aim of this study is to determine the prevalence of antibiotic susceptibility and resistance of Escherichia coli Escherichia coli (E coli) in female uncomplicated cystitis in Korea using meta-analysis. METHODS A cross-search of the literature was performed with MEDLINE for all relevant data published before October 2015 and EMBASE from 1980 to 2015, the Cochrane Library, KoreaMed, RISS, KISS, and DBPia were also searched. Observational or prospective studies that reported the prevalence of antimicrobial susceptibility and resistance of E coli were selected for inclusion. No language or time restrictions were applied. We performed a meta-analysis using a random effects model to quantify the prevalence of antimicrobial susceptibility and resistance of E coli. RESULTS Ten studies were eligible for the meta-analysis, which together included a total of 2305 women with uncomplicated cystitis. The overall resistance rate to antibiotics was 0.28 (95% confidence interval [CI]: 0.25, 0.32). The pooled resistance rates were 0.08 (95% CI: 0.06, 0.11) for cephalosporin, 0.22 (95% CI: 0.18, 0.25) for fluoroquinolone (FQ), and 0.43 (95% CI: 0.35, 0.51) for trimethoprim/sulfamethoxazole (TMP/SMX). Regression analysis showed that resistance to FQ is increasing (P = 0.014) and resistance to TMP/SMX is decreasing (P = 0.043) by year. The generation of cephalosporin was not a significant moderator of differences in resistance rate. CONCLUSION The resistance rate of FQ in Korea is over 20% and is gradually increasing. Although the resistance rate of TMP/SMX is over 40%, its tendency is in decreasing state. Antibiotic strategies used for the treatment of uncomplicated cystitis in Korea have to be modified.

Abstract
OBJECTIVE To establish an apolipoprotein E (ApoE) and low-density lipoprotein receptor (LDLR) double-knockout (ApoE(-/-)/LDLR(-/-)) mouse model of nonalcoholic steatohepatitis (NASH)-related hepatocellular carcinoma (HCC) induced by high-fat and high-cholesterol (HFHC) diet. METHODS ApoE(-/-) knockout mice were crossed with LDLR(-/-) knockout mice to obtain ApoE(-/-)/LDLR(-/-) mice. The ApoE(-/-)/LDLR(-/-) mice mated with each other, and the offspring were injected with low-dose streptozotocin (STZ) at 2-3 days after birth. Some mice were fed with HFHC diet after weaning as the model group (n = 15), and some mice were fed with normal diet as the control group (n = 15). Mice were sacrificed at the end of weeks 10, 16, and 20 (5 mice at each time point). The body weight was measured. Liver tissue and blood were collected to measure biochemical parameters, evaluate the pathological changes in the liver tissue by HE staining, oil red O staining, and Masson staining, and detect the expression of glypican-3 (a marker of HCC) by immunohistochemical staining. RESULTS The model group had significantly higher levels of fasting blood glucose and total cholesterol than the control group (P < 0.01). Serum levels of alanine aminotransferase, aspartate aminotransferase, and total triglyceride gradually increased with time in the model group; at week 20, there were significant differences in above three indices between the two groups (P < 0.05). HE staining showed that compared with the control group at the corresponding time point, the model group developed sequential histological changes: NASH at week 10, dysplastic nodules at week 16, and early HCC at week 20. Oil red O staining showed that in the model group, the degree of liver steatosis increased within 10 weeks and gradually decreased later. Masson staining demonstrated that the model group developed pathological changes: mild perisinusoidal fibrosis at week 16 and bridging fibrosis around tumors at week 20. HE staining, oil red O staining, and Masson staining showed that no histological or pathological changes were found in the control group. Glypican-3 was detected in the nodules at week 16 and in the cytoplasm of HCC cells at week 20 in the model group. CONCLUSION The mouse model of NASH-related HCC can be developed by giving STZ injection to neonatal ApoE(-/-)/LDLR(-/-) mice and feeding them with HFHC diet after weaning for 20 weeks. Early HCC may develop directly from NASH.

Abstract
OBJECTIVES To date, there is no overall agreement as to risk of ambient temperature for lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). Thus, we focused on ambient temperature as an environmental factor affecting LUTS and attempted to explain the temperature differences in LUTS severity in cases in real clinical practice. METHODS This was a multicenter, cross-sectional survey. The study involved 1612 men aged 40 years and older who visited 23 university hospitals in 10 major areas in South Korea between September 2010 and December 2011. The participants who had good overall mental and physical health, and complaint of LUTS were included. Korea Meteorological Administration data were used to determine daily average temperatures and daily temperatures on the interview dates at each site. RESULTS The average age of the 1612 men was 66.57 ± 10.03 years. The mean International Prostate Symptom Score (IPSS) and symptom duration were 18.51 ± 6.77 and 3.79 ± 3.89 years, respectively. Daily average temperature and temperature difference ranged from -13.1 to 28.5 °C and 0 to 20.6 °C, respectively. Age was a significant risk factor for IPSS, symptom duration, prostate volume (PV), maximal urinary flow rate (Qmax), average urinary flow rate (Qave) and total voiding volume (P < 0.001) but not QOL. Logistic regression analysis after adjustment for age and PV revealed that Qave and total voiding volume were increased as the temperature declined. However, IPSS and Qmax did not show a statistically significant difference as the temperature declined. CONCLUSION Our findings did not demonstrate an increased clinically significant risk of LUTS severity in connection with ambient temperature in clinical practice.

Abstract
OBJECTIVE To investigate the relationship between liver cancer and the water environment, we analyzed the life expectancy in 14 counties (districts), which form the Huai River Basin with respect to liver cancer deaths in 2013 and changes in the surface water quality from 2004 to 2010. METHODS The study area included the 14 counties (districts) of the Huai River Basin in China. We obtained surveillance data for all causes of death in the study area during 2013, as well as data for International Classification of Diseases,Tenth Edition(ICD-10) code C22 or liver cancer. Life expectancy and life expectancy after elimination of liver cancer were then calculated. Based on water quality monitoring data from the China Environment Yearbook 2005-2011, we analyzed the water environment of the Huai River Basin, and changes in the water quality. According to the " Encyclopedia of Rivers and Lakes in China" (Huai River Basin section), we divided the river basin into five categories: upstream basin (upstream); midstream, north shore of the basin (midstream-north); midstream, south shore of the basin (midstream-south); downstream basin (downstream); and the Yishusi River Basin. To calculate the life expectancy and life expectancy after elimination of liver cancer in the study area, we used the Nemerow Pollution Index (NPI), to investigate the relationship between liver cancer and the water environment. RESULTS Life expectancy in the 14 study districts varied from 68.99 years (Shenqiu County) to 78.85 years (Jinhu County). Gains in life expectancy after elimination of liver cancer varied from 0.86 to 0.31 years. Midstream-north showed the greatest improvement, with overall gain in life expectancy of 0.77 years; this gain was 1.04 years for males and 0.40 years for females. Yishusi River Basin showed the least improvement, with overall gain in life expectancy of 0.41 years; this gain was 0.54 years for males and 0.24 years for females. For the 7 years from 2004 to 2010, midstream-north had the highest annual NPI values, at 2.08, 1.74, 1.64, 1.81, 1.41, 1.26, and 1.06, respectively. There was a positive correlation between NPI and life expectancy gain for both males and females (r=0.64, P=0.014). There was positive correlation between NPI and life expectancy gain among males alone (r=0.64, P=0.014); there was no significant correlation between NPI and life expectancy gain among females (r=0.44, P=0.115). CONCLUSION Liver cancer had a significant impact on life expectancy in the Huai River Basin. The gain in life expectancy was higher for males than for females. There is a possible relationship between liver cancer deaths and the water environment in the research area, but this study did not infer a causal association.

Abstract
BACKGROUND/AIMS While surgical resection remains the standard of care in the treatment of upper urinary tract malignancies, nephrectomy is a risk factor for the development of chronic kidney disease (CKD). The aim of this study was to determine whether histologic evaluation of non-neoplastic kidney could enable early identification of unrecognized kidney disease and could be of prognostic value in predicting postoperative renal outcomes. METHODS We retrospectively analyzed 51 patients with upper urinary tract malignancies who received uninephrectomy or uninephroureterectomy. A thorough pathologic evaluation of non-neoplastic kidney including special stains, immunofluorescence, and electron microscopic studies was performed. The degree of parenchymal changes was graded from 0 to 15. RESULTS Of 51 patients, only 13 showed normal kidney pathology. Fifteen patients showed glomerular abnormalities, 14 showed diabetic nephropathy, and 11 showed vascular nephropathy. There was one case each of reflux nephropathy and chronic pyelonephritis. The median histologic score was 5 points. Only 25.4% of patients had ≤ 3 points. Score more than 5 was observed in 47.1% of patients. Postoperative estimated glomerular filtration rate (eGFR) at 3 to 36 months were obtained from 90.2% of patients, and of those, 34.8% had de novo CKD. Since no one had CKD in partial nephrectomized patients, we determined risk factors for CKD in radical nephrectomized patients. Cox regression analysis revealed that postoperative AKI, preoperative eGFR, and histologic score of non-neoplastic kidney were the independent predictors for CKD. CONCLUSIONS We conclude that routine pathologic evaluation of non-neoplastic kidney provides valuable diagnostic and prognostic information.

Abstract
Mitochondrial DNA mutations that lead to mitochondrial dysfunction have long been proposed to play important roles in the development of pancreatic cancer. Of these, alterations to mitochondrial tRNA genes constitute the largest group. Most recently, a variation at position 12307 in the gene encoding tRNA(Leu(CUN)) has been reported to be associated with this disease. However, the molecular mechanism underlying this relationship remains poorly understood. To assess this association, we evaluated this variant by evolutionary conservation analysis, measurements of allelic frequencies among control subjects, and use of several bioinformatic tools to estimate potential structural and functional alterations. We found this residue to have a high conservation index; however, the presence of the A12307G variation in control subjects revealed by a literature search suggested it to be common in human populations. Moreover, RNAfold results showed that this variant did not alter the secondary structure of tRNA(Leu(CUN)). Through the application of a pathogenicity scoring system, this variant was determined to be a "neutral polymorphism," with a score of only 4 points based on current data. Thus, the contribution of the A12307G variant to pancreatic cancer needs to be addressed in further experimental studies.

Abstract
OBJECTIVE To investigate the effect of baseline body mass index (BMI) on the risk of lung cancer incidence in male smokers. METHODS All the male employees and retirees of the Kailuan Group were recruited in the Chinese Kailuan Male Cohort Study, and they had been experienced routine physical examinations every two years since May, 2006. Up to 31st December 2011, a total of 3 rounds physical examinations had been completed. A total of 42 718 male smokers candidates from the Chinese Kailuan Male Cohort Study were enrolled in the present study. The date of entering this study was defined as that of taking first check-up, and the date of end-of-observation was defined as that of cancer diagnosis, death or end of follow-up (31 December 2011). Information on demographics, lifestyle such as smoking, alcohol consumption, anthropometries such as height and weight, as well as the information of newly-diagnosed cancer cases, were collected at the baseline investigation. Multivariable Cox proportional hazards regression models were used to investigate the association between levels of the baseline BMI and risk of lung cancer. RESULTS Of the 42 718 male smokers, there were 181 998.09 person-years of follow-up, taking 4.26 years of average follow-up period. During follow-up, 234 new lung cancer cases were identified among the 42 718 male smokers and the crude incidence density was 128.57/100 000. After the factors adjustment for age, education level, alcohol consumption, physical activity, work environment and cumulative smoking levels (pack-years), compared with subjects of normal BMI group, hazard ratio and 95% confidence intervals of lung cancer for subjects of underweight, overweight, and obesity were 1.63 (0.79-3.37), 0.79 (0.57-1.09) and 0.50 (0.27-0.91), respectively. After the facotors adjustment for age, education level, alcohol consumption, physical activity, work environment and cumulative smoking levels (pack-years), compared with subjects of normal BMI, hazard ratio and 95% confidence intervals of lung cancer for subjects of obesity among subjects who aged 50 years or above, smoked more than 20 pack-years, and exercised less than 4 times per week were 0.33 (0.15-0.71), 0.27 (0.10-0.75), and 0.44 (0.20-0.96), respectively. Obesity subjects who worked above the well had decreased risk of lung cancer (HR=0.38, 95% CI: 0.15-0.96) compared with normal BMI ones who worked above the well. CONCLUSION BMI was negatively correlated with the risk of lung cancer in male smokers. As for male smokers, one of the most effective approaches to prevent and control the lung cancer has been shown to quit smoking and keep fit.

Abstract
INTRODUCTION We sought to investigate the impact of fatty liver disease (FLD) on prostate cancer (PCa) screening by estimating the odds of having a prostate-specific antigen (PSA) value over the cutoff used to prompt for the recommendation of prostate biopsy. METHODS Between 2007 and 2013, 18 533 native Korean men eligible to receive a serum PSA test, liver profiles, and abdominal ultrasonography were recruited. Logistic regression was used to estimate the odds of an abnormal PSA (≥2.5 ng/mL) in these men (age 45-75 years, PSA≤10 ng/mL) in relation to FLD. The FLD status was categorized as normal, mild, moderate, and severe grade by abdominal sonography. RESULTS A total of 16 563 men (89.4%) were included in the study after applying the inclusion criteria. Liver profiles were negatively correlated with the serum PSA level. After controlling for age and obesity, there was a statistically significant trend towards a lower likelihood of having a serum PSA level of ≥2.5 ng/mL with severe FLD, having a 34.7% lower likelihood (odds ratio 0.653, 95% confidence interval 0.477-0.88; p<0.01) compared to men in the normal group. CONCLUSIONS Severe FLD is an independent predictor of a lower likelihood of having abnormal PSA level. Further studies are needed to better define these results in clinical biopsy practice.

Abstract
Capparis spinosa L. is an important medicinal species in the Xinjiang Province of China. Ten natural populations of C. spinosa from 3 locations in North, Central, and South Xinjiang were studied using morphological trait inter simple sequence repeat (ISSR) molecular markers to assess the genetic diversity and population structure. In this study, the 10 ISSR primers produced 313 amplified DNA fragments, with 52% of fragments being polymorphic. Unweighted pair-group method with arithmetic average (UPGMA) cluster analysis indicated that 10 C. spinosa populations were clustered into 3 geographically distinct groups. The Nei gene of C. spinosa populations in different regions had Diversity and Shannon's information index ranges of 0.1312-0.2001 and 0.1004-0.1875, respectively. The 362 markers were used to construct the dendrogram based on the UPGMA cluster analysis. The dendrogram indicated that 10 populations of C. spinosa were clustered into 3 geographically distinct groups. The results showed these genotypes have high genetic diversity, and can be used for an alternative breeding program.

Abstract
Snow chrysanthemum (Coreopsis tinctoria Nutt.), a world-widely well-known flower tea material, has attracted more and more attention because of its beneficial health effects such as antioxidant activity and special flavor. In this study, a high performance liquid chromatography coupled with diode array detection and mass spectrometry (HPLC-DAD-MS) and 2,2'-azinobis(3-ethylbenzthiazoline-sulfonic acid)diammonium salt (ABTS) based assay was employed for comparison and identification of antioxidants in different samples of snow chrysanthemum. The results showed that snow chrysanthemum flowers possessed the highest while stems presented the lowest antioxidant capacities. Fourteen detected peaks with antioxidant activity were temporarily identified as 3,4',5,6,7-pentahydroxyflavanone-O-hexoside, chlorogenic acid, 2R-3',4',8-trihydroxyflavanone-7-O-glucoside, flavanomarein, flavanocorepsin, flavanokanin, quercetagitin-7-O-glucoside, 3',5,5',7-tetrahydroxyflavanone-O-hexoside, marein, maritimein, 1,3-dicaffeoylquinic acid, coreopsin, okanin and acetyl-marein by comparing their UV spectra, retention times and MS data with standards or literature data. Antioxidants existed in snow chrysanthemum are quite different from those reported in Chrysanthemum morifolium, a well-known traditional beverage in China, which indicated that snow chrysanthemum may be a promising herbal tea material with obvious antioxidant activity.
