Abstract
Objective: To analyze the status of respiratory pathogen detection and the clinical features in children with Mycoplasma pneumoniae pneumonia (MPP). Methods: A prospective, multicenter study was conducted to collect clinical data, including medical history, laboratory examinations and multiplex PCR tests of children diagnosed with MPP from 4 hospitals in China between November 15th and December 20th, 2023. The multiplex PCR results and clinical characteristics of MPP children in different regions were analyzed. The children were divided into severe and mild groups according to the severity of the disease. Patients in the severe group were further divided into Mycoplasma pneumoniae (MP) alone and Multi-pathogen co-detection groups based on whether other pathogens were detected besides MP, to analyze the influence of respiratory pathogen co-detection rate on the severity of the disease. Mann-Whitney rank sum test and Chi-square test were used to compare data between independent groups. Results: A total of 298 children, 136 males and 162 females, were enrolled in this study, including 204 children in the severe group with an onset age of 7.0 (6.0, 8.0) years, and 94 children in the mild group with an onset age of 6.5 (4.0, 7.8) years. The level of C-reactive protein, D-dimer, lactic dehydrogenase (LDH) were significantly higher (10.0 (5.0, 18.0) vs. 5.0 (5.0, 7.5) mg/L, 0.6 (0.4, 1.1) vs. 0.5 (0.3, 0.6) mg/L, 337 (286, 431) vs. 314 (271, 393) U/L, Z=2.02, 2.50, 3.05, all P<0.05), and the length of hospitalization was significantly longer in the severe group compared with those in mild group (6.0 (6.0, 7.0) vs. 5.0 (4.0, 6.0) d, Z=4.37, P<0.05). The time from onset to admission in severe MPP children was significantly shorter than that in mild MPP children (6.0 (5.0, 9.5) vs. 9.0 (7.0, 13.0) d, Z=2.23, P=0.026). All patients completed the multiplex PCR test, with 142 cases (47.7%) MPP children detected with 21 pathogens including adenovirus 25 cases (8.4%), human coronavirus 23 cases (7.7%), rhinovirus 21 cases (7.0%), Streptococcus pneumoniae 21 cases (7.0%), influenza A virus 18 cases (6.0%). The pathogens with the highest detection rates in Tianjin, Shanghai, Wenzhou and Chengdu were Staphylococcus aureus at 10.7% (8/75), adenovirus at 13.0% (10/77), adenovirus at 15.3% (9/59), and both rhinovirus and Haemophilus influenzae at 11.5% (10/87) each. The multi-pathogen co-detection rate in severe MPP children was significantly higher than that in mild MPP group (52.9% (108/204) vs. 36.2% (34/94), χ²=10.62,P=0.005). Among severe MPP children, there are 89 cases in the multi-pathogen co-detection group and 73 cases in the simple MPP group. The levels of LDH, D-dimer and neutrophil counts in the multi-pathogen co-detection group were significantly higher than those in the simple MPP group (348 (284, 422) vs. 307 (270, 358) U/L, 0.8 (0.5, 1.5) vs. 0.6 (0.4, 1.0) mg/L, 4.99 (3.66, 6.89)×109 vs. 4.06 (2.91, 5.65)×109/L, Z=5.17, 4.99, 6.11, all P<0.05). Conclusions: The co-detection rate of respiratory pathogens, LDH and D-dimer in children with severe MPP were higher than those with mild MPP. Among severe MPP children the stress response of children in co-detection group was more serious than that of children with simple MPP.

Abstract
Purpose Lymphovascular invasion (LVI) and systemic immune-inflammation index (SII) both have been proved to correlate with oncologic outcomes in upper tract urothelial carcinoma (UTUC). We hypothesize that integrating SII with LVI may be an aid for risk-stratification of prognosis. This study aimed to evaluate the prognostic significance of combined SII and LVI in patients with localized UTUC. Patients and Methods A retrospective analysis of clinicopathological data of 554 UTUC patients who underwent radical nephroureterectomy (RNU) was conducted. The SII was calculated using the equation (preoperative serum neutrophil*platelet/lymphocyte). Use of Kaplan–Meier analyses and Cox proportional hazards models were to evaluate associations of combining SII and LVI with overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS). Furthermore, receiver operating characteristic (ROC) analysis was applied to estimate predictive ability of combining SII and LVI for oncological outcomes. Results Positive LVI was significantly associated with advanced stage, high grade, necrosis, lymph node metastasis, and high-level SII. Positive LVI and high-level SII co-existence was significantly associated with unfavorable OS, CSS, and PFS in Kaplan-Meier analyses (all p < 0.001) and was an independent indicator of OS, CSS, and PFS (HR [95% CI]: 3.918 [2.168–7.078], 5.623 [2.679–11.801], 3.377 [2.138–5.334]), respectively) in multivariate analyses. Furthermore, adding LVI and SII to a model that included standard pathologic predictors exhibited a better ability to predict survival in ROC analysis. Conclusion The integration of SII and LVI was demonstrated to be a potential factor of poor outcomes in patients with localized UTUC. Notably, the combined use of LVI and SII can be a feasible and complementary factor to TNM staging in the prognostic assessment of UTUC patients in clinical practice. The validity of combination of the two markers would be considered in future prospective studies to evaluate its usefulness in staging and application of post-operative chemo or immunotherapy.

Abstract
Objective: To explore the value of MRI diffusion tensor imaging (DTI) in the white matter changes of short-term methamphetamine (MA) abstinence. Methods: The data of DTI, demographics features, general information of addiction and impulsivity scale eleven (BIS-11) of 55 short-term MA addicts who were from Changsha, Zhuzhou and Yueyang compulsory detoxification centers in Hunan province, including 40 males and 15 females, aged 14-45 (37.24±7.31) years old, and 52 healthy controls, including 40 males and 12 females aged 18-59 (40.3±9.1) years were collected prospectively from August 2017 to December 2018. The differences of DTI indicators between the two groups were compared by tract-based spatial statistics (TBSS), and then the correlation between the different indicators and the age of first MA use, time of MA use, daily dose used, BIS-11 score were performed. Results: There were significant differences in BIS total score(P<0.001), BIS motivational impulsivity(P<0.001) and BIS attentional impulsivity(P=0.003) between MA group and healthy control group in short-term withdrawal. And compared with the healthy control group, the fractional anisotropy (FA) (0.58±0.02 vs 0.56±0.02,0.77±0.02 vs 0.75±0.04,0.79±0.04 vs 0.76±0.06; all P<0.05), axial diffusivity (AD) (0.57±0.01 vs 0.56±0.02,P=0.001) and mean diffusivity (MD) (0.66±0.02 vs 0.65±0.02,0.52±0.07 vs 0.51±0.06; both P<0.05)values in the MA group were all increased (P<0.05), but there was no significant difference in the radial diffusivity (RD) value (P>0.05). The white matter areas with increased FA value were located in the knee and body of corpus callosum, bilateral anterior corona radiata and left superior corona radiata; the areas with increased AD value were located in the knee, body and pressure of corpus callosum, bilateral anterior limb of internal capsule, posterior limb of internal capsule, anterior, superior and posterior corona radiata, external capsule and superior longitudinal fasciculus; and the areas with increased MD value were mainly located in the right superior longitudinal fasciculus, anterior and posterior limb of internal capsule. The corpus callosum, where there was a difference in FA between the two groups, was positively correlated with the daily dose of MA (r=0.301, P=0.026). Conclusion: MA addicted individuals with short-term withdrawal have white matter edema and damage, and the degree of corpus callosum damage is positively correlated with the daily dose of MA,which is helpful to understand the pathophysiological process of white matter damage in the nervous system and the potential mechanism of neuropsychiatric symptoms in short-term withdrawal MA addicted individuals.

Abstract
The present study aimed to evaluate the influence of pre-treatment neutrophil-to-lymphocyte ratio (NLR) on bladder recurrence in patients with impaired renal function following radical nephrouretectomy (RNU) to treat pure upper tract urothelial carcinoma (UTUC). Retrospective data of 362 patients with pure UTUC who underwent RNU between 2008 and 2019 were analyzed. Kaplan-Meier analyses were performed to evaluate the association of preoperative NLR and estimation of the glomerular filtration rate (eGFR) with intravesical recurrence-free survival (IVRF). Furthermore, multivariate analyses were conducted to determine independent factors for predicting IVRF. In the retrospective cohort study of 362 patients, 103 patients (28%) had intravesical recurrence in a median follow-up of 50.1 months; among those, 85 (83%) developed bladder recurrence within two years after RNU. The Kaplan-Meier analysis indicated that patients exhibiting lower eGFR and higher NLR showed significantly poor IVRF rates (P=0.044). The simultaneous presence of eGFR <45 and NLR >3.8 was an independent factor for the shorter IVRF time in multivariate analysis with Cox's proportional hazards model. Most intravesical recurrences occurred within two years after RNU, particularly in pre-existing poor eGFR patients with preoperative high NLR. Moreover, pre-existing moderate to severe CKD synchronous with pre-operative NLR >3.8 was demonstrated as an independent factor for subsequent bladder recurrence in patients with pure UTUC following RNU. Therefore, such high-risk patients ought to be provided with close bladder monitoring during the follow-up.

Abstract
Background
To explore the dynamic changes and effects of radical cystectomy on quality of life in muscle-invasive bladder cancer survivors.
Methods
Patients with muscle-invasive bladder cancer were randomly recruited in this study. We used the World Health Organization Quality of Life-Brief questionnaire to assess consecutive patients’ quality of life. We applied kernel smoothing to illustrate the dynamic changes of the domain and item scores after treatment. Mixed-effects models were constructed to determine the effects of radical cystectomy on the scores of each item and domain of the World Health Organization Quality of Life-Brief questionnaire after controlling demographic and clinical factors.
Results
We collected 397 repeated measurements of the World Health Organization Quality of Life-Brief questionnaire from 109 muscle-invasive bladder cancer patients. Forty-two of them received radical cystectomy. Patients with radical cystectomy exhibited higher levels of education, less co-morbidities (i.e., diabetes and heart diseases), but were associated with more malignancies. Construction of mixed-effects models showed patients with radical cystectomy and those with bladder sparing had similar scores in the three main domains and their items, except that of certain items of physical domain. By applying kernel smoothing method, we found that stage III–IV patients consistently showed higher scores on sleep and rest after radical cystectomy for more than 5 years. In contrast, stage II patients receiving radical cystectomy did not show a higher score on the “sleep and rest” item compared with those with bladder sparing operation.
Conclusions
Radical cystectomy may result in sound sleep and rest, especially in those with stage III–IV bladder cancer.

Abstract
Objective: To analyze the effect and main gaps of each stage in the AIDS prevention cascade for men who have sex with men (MSM) provided in intervention projects supported by the China AIDS Fund for non-governmental organizations (CAFNGO) and provide suggestions to improve the quality of cascade services and project management. Methods: Data were collected through the CAFNGO management information system and field interviews to analyze the differences in the number of MSM receiving HIV testing and confirming tests, the newly reported patients, and the number of antiviral treatment (ART) referrals of newly established reported patients among different social organization service areas. A service chain chart was also drawn. Results: Between 2016 and 2020, 1 508 MSM intervention projects were funded by CAFNGO, including 1 183 234 MSM being mobilized to receive HIV testing. However, only 68.8% (1 183 234/1 719 139) of the testing capacity of social organizations was covered by these projects. As a result, 55 783 HIV-positive MSM were detected in preliminary screening, and only 86.6% (48 327/55 783) received confirming tests. The proportion of newly reported infections was 3.8% (45 347/1 183 234). The ratio of antiviral treatment (ART) referrals for newly reported patients between 2017 and 2020 was 89.8% (32 719/36 444). 75.8%(1 143/1 508) of total MSM intervention projects were implemented by community-based organizations (Non-registered civil affairs departments). In comparison, organizations registered in civil affairs departments took up 24.2% (365/1 508) of the total MSM intervention projects. No significant difference was noticed in the proportion of newly reported infected (3.8% and 3.8%) and the ratio of ART referrals (89.7% and 89.9%) between community-based organizations and registered organizations' projects. But these two proportions are significantly different between these two types of organizations in some areas in China. Conclusions: The AIDS prevention cascade established in CAFNGO has effectively promoted the early detection and treatment of infected MSM. However, CAFNGO needs more financial support to extend testing coverage for MSM. Meanwhile, confirmation testing for positives in preliminary screening and ART referrals needs to be improved for newly reported patients. In addition, various capacity building needs to be provided for different social organizations.

Abstract
Objective: To analyze the clinical characteristics and related genetic variation of juvenile myasthenia gravis (MG) patients. Methods: We collected the clinical data of adolescent MG patients who were treated in the Department of Neurology of the First Affiliated Hospital of Sun Yat-sen University from June 2019 to May 2020. After obtaining the patient's informed consent, the blood samples were collected. The Whole Exome Sequencing (WES) was performed on peripheral blood samples. And use biological information software and SPSS 22.0 for data processing and result analysis. Results: According to the inclusion and exclusion criteria, 54 patients with juvenile MG were included, 28 males and 26 females. And the average age of onset was (3.79±0.89) years. Among the enrolled patients, there were 52 (96.3%) patients with ocular MG, the MG-ADL scores of 54 patients were (3.44±0.44) points, and the titer of AChR antibody was (5.88±2.45) nmol/L. Two patients had thymic hyperplasia, and 5 patients had a family history of MG.A total of 169 variant genes were found in 54 patients, of which TTN gene variants had the largest number, with a total of 17 variants (31.5%). In the TTN gene variant group, 7(41.2%) patients had eye fixation symptoms, and 4 (10.8%) patients in the non-mutation group had eye fixation symptoms. And The difference between the two groups was statistically significant (P=0.016). In addition, the synaptic nucleus envelope protein-1 (SYNE1) and the ryanodine receptor-1 (RYR1) gene variations were also found in 7 cases (13.2%), and no clear relationship between these gene variations and clinical manifestations of MG was found. Conclusions: The incidence of juvenile MG was preschoolers with no gender difference, and ocular MG was more common. The proportion of TTN gene variation in adolescent MG was higher, suggesting that this gene may be a potential therapeutic target for juvenile MG patients.

Abstract
Objective: To explore the application of multidisciplinary treatment (MDT) and comprehensive management model in the diagnosis and treatment of early-stage lung cancer, and analyze its clinical value and the feasibility and significance of promotion. Methods: A retrospective study of 470 patients in Xijing Hospital who underwent surgery after MDT from January 8, 2018 to December 31, 2019. There were 172 males and 298 females, aged from 23 to 79 (54.46±11.08) years. Basic diagnosis and treatment information as well as postoperative pathology were analyzed, of which 441 cases were recommended for surgery by MDT and 29 cases were subjectively requested for surgery. The patients' general condition, preoperative diagnosis and pathological results were compared, and the specific content of the MDT and comprehensive management model were summarized. We also explored the value of MDT integrated management model in early stage lung cancer treatment in the context of the current lung cancer incidence in China. Results: Among 470 surgical patients, the majority of males had solid nodules (69/172,40.1%), and the majority of females had ground glass nodules (135/298,45.3%). The distribution of nodules showed a trend of more upper lobe(277/470)than lower lobe(161/470) and more right lung(276/470) than left lung(194/470). Among the 441 patients recommended for surgery, 98.11% of males (156/159) and 97.87% of females (276/282) showed malignant pathology after surgery. Adenocarcinoma was the main pathological type (93.59% of males, 146/156; 97.46% of females, 269/276). Among the malignant pathological results, carcinoma in situ (42.31% of males, 66/156; 47.10% of females, 130/276) and stage I lung cancer (50.64% of males, 79/156; 47.46% of females, 131/276) were the most common. In all patients, 1.89% of the males (3/159) and 2.13% of the females (6/282) recommended for surgery showed benign postoperative pathology, of which tuberculosis and fungal infection were the main pathological types (66.67% for each gender, males 2/3, females, 4/6). The postoperative pathology of 29 patients who subjectively requested surgery was also tuberculosis and fungal infection as the main pathological types (69.23% of males, 9/13; 68.75% of females, 11/16). The MDT comprehensive management model made full use of a variety of auxiliary diagnostic technologies and combined the experience advantages of multidisciplinary participation to make up for the limitations of single-diagnosis. The overall diagnosis coincidence rate reached 98.09%, with strong consistency (Kappa>0.81). The positive predictive value (PPV) was 97.96%, the negative predictive value (NPV) was 100%, and the average patient diagnosis and treatment cycle was 24.28-26.51 days. Conclusions: The MDT comprehensive management model meets the consensus requirements. It has great advantages in diagnostic efficiency and diagnosis and treatment cycle, and has a high promotion and application value for the diagnosis and treatment of early-stage lung cancer. At the same time, tuberculosis and fungal infection should be regarded as an important differential diagnosis item.

Abstract
Objective: To evaluate the demographics, etiology composition, clinical characteristics and surgical outcomes of acquired ptosis patients. Methods: Retrospective case-series study. The clinical records of 176 consecutive patients (312 eyes) with acquired ptosis were reviewed from January 2009 to December 2018 in the Ophthalmology Department of Tianjin Medical University General Hospital. The demographics, etiology composition, clinical characteristics, surgical strategies and outcomes were analyzed. Results: There were 59 male (33.5%) and 117 female (66.5%) patients suffering acquired ptosis, with an average age of (64±7) years. The disease was bilateral in 136 cases and unilateral in 40 cases. There were four etiological components of acquired ptosis: 145 cases (82.4%) of aponeurotic ptosis, 17 cases (9.6%) of neurogenic ptosis, 10 cases (5.7%) of myogenic ptosis and 4 cases (2.3%) of traumatic ptosis. The clinical characteristics of acquired ptosis varied significantly depending on etiology. Ptosis surgeries were performed on 152 cases (279 eyes), and the success rate was 92.1% (140/152). Surgical procedures included levator aponeurosis surgeries on 148 cases (275 eyes), frontal muscle suspensions on 2 cases (2 eyes) and conjunctival-Müller's ectomies on 2 cases (2 eyes). Conclusions: Acquired ptosis is more likely to occur in senile and female populations with bilateral eyelids involved mostly. Aponeurotic ptosis is the predominant type of acquired ptosis. The treatment is performed according to the clear etiological diagnosis based on clinical features, and operations are efficient for most patients with acquired ptosis.

Abstract
Objective: To understand the capacity building needs on social organizations providing HIV prevention and treatment services for female sex workers (FSW). Methods: Questionnaires and interview were conducted with the heads of social organizations participating in China AIDS Fund for Non-Governmental Organizations (CAFNGO) project 2017-2018. Data from the CAFNGO's information system were compiled and analyzed using Excel 2016 and SPSS 25.0 software. The distribution of social organizations, availability of funds, and social organizations' needs for capacity building were analyzed. Results: Nationwide, 184 social organizations were involved in project '2017-2018 CAFNGO's FSW field work'. Out of which, 156 answers were valid. Social organizations that participated in the implementation of fund projects were mainly concentrated in the western region, accounting for 44.0% (81/184), with Sichuan, Guangxi, and Yunnan being the majority. However, the eastern part received the most financial support. Social organizations expressed the highest demand for project data collection and analysis, accounting for 68.6% (107/156). Items on risk analysis, response, and quality control project ranked the second, accounting for 64.1% (100/156). Results showed that statistically significant differences were seen on capacity building needs among social organization leaders with different levels of training on management of planning and finance of the project (χ2=5.78,P=0.016;χ2=8.99,P=0.003). Conclusions: Currently, the number of social organizations and the related fund provision concerning HIV prevention and control among FSWs were not consistent in China. Thus, it is necessary to encourage, guide, and support the development of social organizations and satisfy social organizations' needs on capacity-building and planning.

Abstract
Background An objective of the phase 3 HELP Study was to investigate the effect of lanadelumab on health‐related quality of life (HRQoL) in patients with hereditary angioedema (HAE). Methods Patients with HAE‐1/2 received either lanadelumab 150 mg every 4 weeks (q4wks; n = 28), 300 mg q4wks (n = 29), 300 mg every 2 weeks (q2wks; n = 27), or placebo (n = 41) for 26 weeks (days 0–182). The Angioedema Quality of Life Questionnaire (AE‐QoL) was administered monthly, consisting of four domain (functioning, fatigue/mood, fears/shame, nutrition) and total scores. The generic EQ‐5D‐5L questionnaire was administered on days 0, 98, and 182. Comparisons were made between placebo and (a) all lanadelumab‐treated patients and (b) individual lanadelumab groups for changes in scores (day 0–182) and proportions achieving the minimal clinically important difference (MCID, −6) in AE‐QoL total score. Results Compared with the placebo group, the lanadelumab total group demonstrated significantly greater improvements in AE‐QoL total and domain scores (mean change, −13.0 to −29.3; p < 0.05 for all); the largest improvement was in functioning. A significantly greater proportion of the lanadelumab total group achieved the MCID (70% vs 37%; p = 0.001). The lanadelumab 300 mg q2wks group had the highest proportion (81%; p = 0.001) and was 7.2 times more likely to achieve the MCID than the placebo group. Mean EQ‐5D‐5L scores at day 0 were high in all groups, indicating low impairment, with no significant changes at day 182. Conclusion Patients with HAE‐1/2 experienced significant and clinically meaningful improvements in HRQoL measured by AE‐QoL following lanadelumab treatment in the HELP Study.

Abstract
Reservoir computing (RC) is a recently introduced bio-inspired computational framework capable of excellent performances in the temporal data processing, owing to its derivation from the recurrent neural network (RNN). It is well-known for the fast and effective training scheme, as well as the ease of the hardware implementation, but also the problematic sensitivity of its performance to the optimizable architecture parameters. In this article, a particular time-delayed RC with a single clamped-clamped silicon beam resonator that exhibits a classical Duffing nonlinearity is presented and its optimization problem is studied. Specifically, we numerically analyze the nonlinear response of the resonator and find a quasi-linear bifurcation point shift of the driving voltage with the driving frequency sweeping, which is called Bifurcation Point Frequency Modulation (BPFM). Furthermore, we first proposed that this method can be used to find the optimal driving frequency of RC with a Duffing mechanical resonator for a given task, and then put forward a comprehensive optimization process. The high performance of RC presented on four typical tasks proves the feasibility of this optimization method. Finally, we envision the potential application of the method based on the BPFM in our future work to implement the RC with other mechanical oscillators.

Abstract
To analysis the treatment effectiveness of maxillofacial arteriovenous malformation (AVM) by means of temporary balloon block and percutaneous puncture sclerotherapy. The treatment outcomes of 20 patients with AVM of maxillofacial deformity, aged (26.8±3.0) 18-36 years, from Dec 2012 to Dec 2019 were collected and retrospectively analyzed. All patients had been diagnosed AVM by digital substraction angiography (DSA). All the cases were treated by using balloons to temporary block responsible artery of the AVM in order to change the high-flow malformations into low-flow venous malformation. Then injection of polyethylene foam cinnamyl alcohol was conducted via percutaneous puncturing for hardening the vascular malformation. Comparing the symptoms and imaging changes before treatment with those 1-6 months after treatment according to Achauer curative effect evaluation standard. Totally 60% (12/20) of the cases were type Ⅱa AVM, and their treatments were effective. However, the treatment effects of type Ⅲb and type Ⅳ patients were relatively poor. The clinical effective rate was 85% (17/20), and the clinical curative rate was 50% (10/20). No skin necrosis, organ damage and other serious complications were observed for the 20 patients. The AVM patients with a main supply artery treated by using a balloon artery temporary block to make high flow malformations into low-flow and followed by percutaneous puncture sclerotherapy, could get good curative effect. It seemed that this approach was safe and effective.

Abstract
BACKGROUND Aristolochic acids (AA) and arsenic are chemical carcinogens associated with urothelial carcinogenesis. Here we investigate the combined effects of AA and arsenic toward the risk of developing upper tract urothelial carcinoma (UTUC). METHODS Hospital-based (n = 89) and population-based (2,921 cases and 11,684 controls) Taiwanese UTUC cohorts were used to investigate the association between exposure to AA and/or arsenic and the risk of developing UTUC. In the hospital cohort, AA exposure was evaluated by measuring aristolactam-DNA adducts in the renal cortex and by identifying A>T TP53 mutations in tumors. In the population cohort, AA exposure was determined from prescription health insurance records. Arsenic levels were graded from 0 to 3 based on concentrations in well water and the presence of arseniasis-related diseases. RESULTS In the hospital cohort, 43, 26, and 20 patients resided in grade 0, 1+2, and 3 arseniasis-endemic areas, respectively. Aristolactam-DNA adducts were present in >90% of these patients, indicating widespread AA exposure. A>T mutations in TP53 were detected in 28%, 44%, and 22% of patients residing in grade 0, 1+2, and 3 arseniasis-endemic areas, respectively. Population studies revealed that individuals who consumed more AA-containing herbs had a higher risk of developing UTUC in both arseniasis-endemic and nonendemic areas. Logistic regression showed an additive effect of AA and arsenic exposure on the risk of developing UTUC. CONCLUSIONS Exposure to both AA and arsenic acts additively to increase the UTUC risk in Taiwan. IMPACT This is the first study to investigate the combined effect of AA and arsenic exposure on UTUC.

Abstract
Background Lanadelumab demonstrated efficacy in preventing hereditary angioedema (HAE) attacks in the phase 3 HELP Study. Objective To assess time to onset of effect and long‐term efficacy of lanadelumab, based on exploratory findings from the HELP Study. Methods Eligible patients with HAE type I/II received lanadelumab 150 mg every 4 weeks (q4wks), 300 mg q4wks, 300 mg q2wks, or placebo. Ad hoc analyses evaluated day 0‐69 findings using a Poisson regression model accounting for overdispersion. Least‐squares mean monthly HAE attack rate for lanadelumab was compared with placebo. Intrapatient comparisons for days 0‐69 versus steady state (days 70‐182) used a paired t test for continuous endpoints or Kappa statistics for categorical endpoints. Results One hundred twenty‐five patients were randomized and treated. During days 0‐69, mean monthly attack rate was significantly lower with lanadelumab (0.41‐0.76) vs placebo (2.04), including attacks requiring acute treatment (0.33‐0.61 vs 1.66) and moderate/severe attacks (0.31‐0.48 vs 1.33, all P ≤ .001). More patients receiving lanadelumab vs placebo were attack free (37.9%‐48.1% vs 7.3%) and responders (85.7%‐100% vs 26.8%). During steady state, the efficacy of lanadelumab vs placebo was similar or improved vs days 0‐69. Intrapatient differences were significant with lanadelumab 300 mg q4wks for select outcomes. Lanadelumab efficacy was durable—HAE attack rate was consistently lower vs placebo, from the first 2 weeks of treatment through study end. Treatment emergent adverse events were comparable during days 0‐69 and 70‐182. Conclusion Protection with lanadelumab started from the first dose and continued throughout the entire study period.

Abstract
OBJECTIVE To investigate the prevalence and changing patterns of Schistosoma japonicum infections in goats in Dantu District of Zhenjiang City, so as to provide the scientific data for the management of in livestock. METHODS The S. japonicum infections were detected using a miracidial hatching test (one test for one stool specimen) in goats grazed in settings with snail habitats in Dantu District of Zhenjiang City at spring and autumn of each year from 2004 to 2019, and the prevalence and intensity of S. japonicum infections were estimated. RESULTS A total of 21 836 goat stool samples were detected from 2004 to 2019, and 86 were positive for S. japonicum (0.39% prevalence). The highest prevalence of S. japonicum infections in goats was seen in 2004 (1.25%) and no infections were detected in goats since 2013. S. japonicum-infected goats were identified in marshland-type endemic areas and plain regions with waterway networks, and there was a significant difference in the prevalence of S. japonicum infections in goats between these two types of endemic areas (0.50% vs. 0.15%; χ2 = 11.566, P < 0.05). The prevalence of S. japonicum infections was significantly greater in goats at ages of more than 10 months (0.51%) and over 10 months (0.44%) than in other goats (χ2 = 13.088, P < 0.05), and higher prevalence was found in autumn than in spring (0.54% vs. 0.27%; χ2 = 9.597, P < 0.05). In addition, there were 76.74% of S. japonicum-infected goats with intensity of"+++"and"++++". CONCLUSIONS Although the high prevalence of S. japonicum infections has been effectively controlled in goats in Dantu District, goat remains to be an important source of S. japonicum infections that should be given a high priority for control to consolidate the schistosomiasis control achievements.

Abstract
Prostatic enlargement might affect up to 30% of men and can cause signs and symptoms in the lower urinary tract in the elderly. Imbalanced estrogen and androgen secretions are important in prostatic physiopathology. Phthalates-environmental endocrine disruptors-affect androgen secretion and disrupt sexual organs, including testes and the prostate, but the underlying mechanisms are unclear. Using European Association of Urology (EAU) guidelines, we recruited from urology clinics in southern Taiwan 207 elderly men diagnosed with benign prostatic hyperplasia (BPH) and prostatic enlargement between 2015 and 2017. We took blood and urine samples from all patients on the same day. We used multivariate linear regression, associations, and potential interactions after we had measured and analyzed oxidative stress (OS) markers, steroidal hormones, and 11 urinary phthalate metabolites, and then we adjusted for confounders. Di(2-ethylhexyl) phthalate (DEHP) metabolite levels, particularly urinary mono-(2-ethylhexyl) phthalate, were positively associated with androgen, estrogen, hormone ratios, inducible nitric oxide synthetase (iNOS), 8-hydroxy-2'-deoxyguanosine (8-OHdG), prostate specific antigen (PSA), and prostate volume (PV) (p < 0.05). PV and PSA were positively associated with androgen, estrogen, hormone ratios and OS markers (p < 0.05). The estimated percentages of exposure to phthalates in prostatic enlargement mediated by androgen, estrogen, and OS markers ranged from 3.5% to 63.1%. Exposure to DEHP promoted the progress of BPH by increasing dihydrotestosterone (DHT), estradiol (E2), the converted enzymes aromatase and 5α reductase, and reactive oxygen species (ROS) (8-OHdG and iNOS) production. Sex hormones and OS might be important hyperplasia-promoters after a patient has been exposed to phthalates, especially to DEHP.

Abstract
OBJECTIVES To determine the optimal surgical timing in high-risk patients with Fournier's gangrene by the Simplified Fournier's Gangrene Severity Index. METHODS From 1989 to 2018, 118 male patients diagnosed with Fournier's gangrene with complete medical records were retrospectively reviewed. Patients' demographics, laboratory parameters at initial diagnosis, Fournier's Gangrene Severity Index and Simplified Fournier's Gangrene Severity Index, and the time interval from emergency room arrival to surgical intervention were collected. The Fournier's gangrene patients were categorized into low-risk (Simplified Fournier's Gangrene Severity Index ≤2) and high-risk groups (Simplified Fournier's Gangrene Severity Index >2). Differences between the variables within the two groups were analyzed. The optimal surgical timing was analyzed with the receiver operating characteristic curve in high-risk Fournier's gangrene patients. RESULTS The overall mortality of 118 Fournier's gangrene patients was 14.4%. After risk stratification with the Simplified Fournier's Gangrene Severity Index scoring system, the mortality of low-risk and high-risk Fournier's gangrene patients was 1.3% and 41.0%, respectively. In the high-risk group, the time interval from emergency room arrival to surgical intervention was the only variable with a significant difference between survivors and non-survivors (P = 0.039). The optimal surgical timing was determined at 14.35 h, which allowed the highest sensitivity (0.688) and specificity (0.762) to affect mortality. The mortality was significantly lower in high-risk Fournier's gangrene patients with early surgical intervention compared with late intervention (23.8% vs 68.8%, P = 0.007). CONCLUSIONS The Simplified Fournier's Gangrene Severity Index is a quick and reliable screening tool for first-line physicians to identify high-risk patients with Fournier's gangrene (Simplified Fournier's Gangrene Severity Index >2) who have poor survival outcomes. We recommended early surgical intervention within 14.35 h to maximize the survival of high-risk Fournier's gangrene patients.

Abstract
BACKGROUND This study aimed to evaluate the clinical significance of the preoperative systemic immune-inflammation index (SII) combined with the monocyte-lymphocyte ratio (MLR) for patients with upper-tract urothelial carcinoma (UTUC). METHODS The clinical data of 424 patients who underwent radical nephroureterectomy from January 2007 to June 2017 were analyzed. Kaplan-Meier analyses and Cox proportional hazards models were used to evaluate associations of preoperative systemic immune-inflammatory biomarkers with overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS). Moreover, logistic regression preoperative models were applied to predict advanced disease. RESULTS Multivariate analyses showed that SII significantly influenced both OS and CSS (both P < 0.05), whereas MLR exhibited the most significant association with OS (P = 0.008). In particular, simultaneously high SII and MLR values correlated significantly with OS, CSS, and PFS (all P < 0.05). Logistic regression preoperative models showed that the combination of high SII and high MLR was a significant predictor of non-organ-confined UTUC (P = 0.001). Furthermore, Kaplan-Meier analysis showed that the combination of high SII and high MLR was significantly linked with poor OS, CSS, and PFS in non-organ-confined UTUC (all P < 0.05). CONCLUSION The study reviewed serum inflammation biomarkers in a subset of patients with UTUC and demonstrated the ability of combined SII and MLR to predict disease progression and survival. Patients with both high SII and high MLR were significantly more likely to have non-organ-confined disease and poor survival outcomes.

Abstract
Background To explore the feasibility and long-term outcomes of renal preservation in a retrospective cohort of patients with ureteral urothelial carcinoma undergoing total ureterectomy with ileal-ureteral substitution. Methods A retrospective review of the data from patients treated with total ureterectomy with ileal-ureteral substitution from 1988 to 2016 was performed. The pre-operative oncological status, long-term oncological outcome, long-term renal functional outcome, early and late complications were analyzed. Results A total of eight patients with a median age of 70 years were included. The median follow-up time was 109 months. Six patients had multi-focal tumor involvement over the target ureter, and six patients had bilateral upper tract involvement. Only one patient encountered the upper-tract recurrence. The 2 and 5-year cancer-specific survival rates were 87.5 and 75.0%, respectively. The renal function was well-preserved in most patients, with only one patient needed life-long postoperative hemodialysis. Five patients experienced early complications and four patients experienced late complications. No perioperative mortality happened. Conclusions A total ureterectomy with an ileal-ureteral substitution is feasible for treating ureteral urothelial carcinoma when a renal-sparing procedure is indicated. It provides good long-term oncological outcomes over the upper tract, and it also preserves the renal function.

Abstract
Hypoxia-inducible factor-1α (HIF-1α) can control a transcriptional factor forkhead box P3 (Foxp3) protein expression in T lymphocyte differentiation through proteasome-mediated degradation. In this study, we unveil a reverse regulatory mechanism contributing to bladder cancer progression; Foxp3 expression attenuates HIF-1α degradation. We first demonstrated that Foxp3 expression positively correlates with the metastatic potential in T24 cells and can increase the expression of HIF-1α-target genes, such as vascular endothelial growth factor (VEGF) and glucose transporter (GLUT). Foxp3 protein can bind with HIF-1α, particularly under hypoxia. In vivo ubiquination assay demonstrated that Foxp3 can decrease HIF-1α degradation in a dose-dependent manner. Knocking-down of Foxp3 expression blocks in vivo tumor growth in mice and prolongs mice's survival, which is associated with von Willebrand factor expression. Thirty-three of 145 (22.8 %) bladder tumors exhibit Foxp3 expression. Foxp3 expression is an independent predictor for disease progression in superficial bladder cancer patients (p = 0.032), associated with less number of intratumoral CD8+ lymphocyte. The metaanalysis from 2 published datasets showed Foxp3 expression is positively associated with GLUT−4, −9, and VEGF-A, B-, D expression. This reverse post-translational regulation of HIF-1α protein by Foxp3 provides a new potential target for developing new therapeutic strategy for bladder cancer.

Abstract
Objective: To understand the genetic and molecular epidemiologic characteristics of 63 strains of Japanese encephalitis virus (JEV) isolated in Yunnan province, China during 1977-2010. Methods: Suckling mice were inoculated with viruses continuously and the viral nucleic acid were extracted from the brain-grinding supernatants of the infected and moribund mice, then the gene fragments of E region were amplified by RT-PCR. Bioinformatics (Clustal X, DNAstar, Mega 5.0 and other software) was used to analyze the nucleotide and deduced amino acid sequences and phylogenetic trees. Results: Yunnan strains of JEV could cause illness and deaths in suckling mice. The results of virus nucleic acid detection and sequencing indicated that nucleotide sequences of E gene of the 63 virus strains were obtained. Phylogenetic tree and homology analyses based on E genomes showed that 47 strains of the experimental virus belonged to genotype 1 (G-1) and 16 strains belonged to genotype 3 (G-3). The 47 isolates of G-1 were divided into 2 clades, of them, the earliest isolates of G-1 (M28, 1977 and BN82215, 1982) in Yunnan of China and the early isolates of G-1 (U70416, 1982; DQ084229, the year is unknown) in Thailand were in one clade, and the isolates of G-1 from 2007-2010 in Yunnan could be divided into 2 subgroups. The 16 isolates of G-3 from Yunnan were divided into 3 clades, among them, the isolates from 1970-1990s in Yunnan were in two clades, and the isolates from 2004 in Yunnan were in one clade. In addition, their main amino acid sites of antigenicity, pathogenic, virulence of both G-1 and G-3 had no significant change. Conclusion: JEV G-1 and G-3 co-circulated in Yunnan, and G-1 was predominant. The JEV strains isolated in different years and areas in Yunnan had different molecular epidemiologic characteristics and genetic diversity. The results of this study suggested that JEV G-1 might originate from Yunnan of China and adjacent Southeast Asia region.

Abstract
Dark plasmonic resonances in metallic nanostructures are essential for many potential applications such as refractive index sensing, single molecule detection, nanolasers etc. However, it is difficult to excite the dark modes in optical experiments and thus the practical applications are severely limited. Herein, we demonstrate a simple method to experimentally excite the quadrupolar and higher-order plasmonic modes with normal incident light. By directionally depositing silver films onto the sidewalls of metal-covered one-dimensional grating, we have experimentally observed a series of asymmetrical resonances at the plasmonic ranges of silver gratings. Interestingly, both of the reflection and transmission coefficients of high-order plasmonic modes are reduced to around zero, demonstrating the perfect absorption very well. The corresponding numerical simulations show that these resonances are the well-known dark modes. Different from the conventional dark modes in plasmonic dimers, here the dark modes are the electric oscillations (as standing waves) within the silver sidewalls that are excited by charge accumulation via the bright plasmonic resonance of the top silver strips. In addition to the simple realization of perfect absorption, the dark modes are found to be quite sensitive to the environmental changes. The experimentally measured reflective index sensitivity is around 458 nm per RIU (refractive index unit), which is much higher than the sensitivity of the metal-covered grating without silver sidewalls. This research shall pave new routes to practical applications of dark surface plasmons.

Abstract
Cancer cells initially characterized as sensitive to chemotherapy may acquire resistance to chemotherapy and lead to tumor recurrence through the expansion of drug-resistant population. Acquisition of drug resistance to conventional chemotherapy is a major obstacle in the treatment of recurrent cancer. Here we investigated whether anticancer drugs induced Oct4 expression, thereby contributing to acquired drug resistance and tumor recurrence in bladder cancer. We identified a positive correlation of Oct4 expression with tumor recurrence in 122 clinical specimens of superficial high-grade (stages T1-2) bladder transitional cell carcinoma (TCC). Increased Oct4 levels in bladder tumors were associated with short recurrence-free intervals in the patients. Chemotherapy induced Oct4 expression in bladder cancer cells. Notably, treatment with cisplatin increased CD44-positive bladder cancer cells expressing Oct4, representing cancer stem-like cell subpopulation. Forced expression of Oct4 reduced, whereas knockdown of Oct4 enhanced, drug sensitivity in bladder cancer cells. Furthermore, tumor cells overexpressing Oct4 responded poorly to cisplatin in vivo. In regard to clinical relevance, inhibition of Oct4 by all-trans retinoic acid (ATRA) synergistically increased sensitivity to cisplatin in bladder cancer cells. Furthermore, the combination of cisplatin and ATRA was superior to cisplatin alone in suppressing tumor growth. Therefore, our results provide evidence that Oct4 increases drug resistance and implicate that inhibition of Oct4 may be a therapeutic strategy to circumvent drug resistance.

Abstract
BACKGROUND AND AIMS Iron metabolism plays a crucial role in the development of cardiometabolic disease; however, the association between cardiometabolic risk factors (CMRFs) and hepcidin as well as other iron parameters remains unclear in children. The aims of this study were to compare the circulating hepcidin levels and iron metabolism between children with and without CMRFs and to investigate the association between those iron parameters and CMRFs. METHODS AND RESULTS A case-control study was conducted among 1126 children aged 7-14 years in the case group (n = 563) with CMRFs and the healthy control group (n = 563). Iron parameters, lipids, and anthropometric characteristics were evaluated. The information on demographics, diet, and physical activities was either children reported or parent reported. Compared with the healthy controls, children with CMRFs had higher levels of hepcidin and lower levels of serum iron, transferrin, and soluble transferrin receptor (sTfR; P < 0.001). Besides, the odds ratios (ORs) for low levels of high-density lipoprotein (HDL) were 2.03, 0.21, and 0.33 in children with higher hepcidin, transferrin, and sTfR levels (P < 0.05). Furthermore, ORs for cardiometabolic risk were 0.50 (95% confidence interval (CI): 0.30-0.85, P < 0.05), 0.22 (95% CI: 0.12, 0.42, P < 0.01) and 0.19 (95% CI: 0.10, 0.36, P < 0.01) in children with higher serum iron, transferrin, and sTfR levels, respectively. CONCLUSION The levels of hepcidin were higher, while those of iron, transferrin, and sTfR were lower in children with CMRF. Hepcidin was positively associated with the risk of low HDL levels, whereas transferrin and sTfR levels negatively correlated with the risk of low HDL levels. In addition, serum iron, transferrin, and sTfR levels were negatively associated with cardiometabolic risk.

Abstract
OBJECTIVE To evaluate the effect of phacoemulsification on intraocular pressure (IOP) in filtered eyes with primary angle closure glaucoma (PACG). METHODS In this retrospective case series, 47 eyes from 47 PACG patients who previously had trabeculectomy were consecutively enrolled. All patients had visually significant cataracts and phacoemulsification was performed at least 3 months after trabeculectomy. The IOPs were recorded preoperatively, 1 day, 1 week, 2 weeks, 1 month, 3 months, 6 months, 12 months and 24 months after surgery. The best correct visual acuity (BCVA) , the number of glaucoma medications and the filtered bleb grade were recorded preoperatively and 24 months after phacoemulsification. IOP and BCVA before and after phacoemulsification were compared by student t test. The frequences of antiglaucoma medicine, bled grade and IOP control before and after phacoemulsification were compared by Mann-Whitney Test. Linear regression analysis, Pearson and Spearman were performed to assess the correlation between IOP change and other variants. RESULTS IOP was decreased significantly from (18.7±6.7) mmHg (1 mmHg=0.133 kPa) at baseline to 16.4±2.0 mmHg at final follow-up (t=2.54, P=0.015) . The median number of glaucoma medications was significantly decreased (P<0.01) at 2 years postoperatively. The magnitude of IOP reduction was significantly correlated with preoperative IOP (r=0.95, P<0.01). BCVA (LogMAR) was improved significantly at month 24 (t=5.62, P<0.01). Filtered bleb decreased insignificantly at 2 years postoperatively (P=0.113). Complete success, qualified success and failure rates in terms of IOP were 61.7%, 27.7% and 10.6% before surgery , 89.4%, 8.5%, 2.1% at 2 years postoperatively. In 29 patients with preoperative IOP≤21 mmHg, mean IOP increased insignificantly from (14.5±4.0) mmHg to (15.5 ± 2.3) (P=0.195) at 2 years. In the 18 patients with preoperative IOP> 21 mmHg, mean IOP decreased from (25.3 ± 4.4) mmHg preoperatively to (17.8 ± 2.4) mmHg (P<0.01). CONCLUSIONS Phacoemulsification reduces IOP and the number of glaucoma medications in previously filtered PACG eyes. The IOP remained normal in normal tension eyes after phacoemulsification in filtered PACG eyes but decreased significantly in hypertensive eyes.

Abstract
Transforming growth factor β (TGFβ) regulates cell proliferation, differentiation, migration, apoptosis, and extracellular matrix production. It also plays a pivotal role in the pathogenesis of gingival overgrowth. Thrombin is a key player in tissue repair, remodeling, and fibrosis after an injury, and it exerts profibrotic effects by activating protease-activated receptors. Connective tissue growth factor (CTGF or CCN2) modulates cell adhesion, migration, proliferation, matrix production, and wound healing. It is overexpressed in many fibrotic disorders, including gingival overgrowth, and it is positively associated with the degree of fibrosis in gingival overgrowth. In human gingival fibroblasts, we previously found that TGFβ1 induced CCN2 protein synthesis through c-jun N-terminal kinase and Smad3 activation. Thrombin stimulates CCN2 synthesis through protease-activated receptor 1 and c-jun N-terminal kinase signaling. Curcumin inhibited TGFβ1- and thrombin-induced CCN2 synthesis. In this study, we demonstrated that thrombin and protease-activated receptor 1 agonist SFLLRN induced latent TGFβ1 activation and Smad3 phosphorylation in human gingival fibroblasts. Pretreatment with a TGFβ-neutralizing antibody, TGFβ type I receptor inhibitor SB431542, and Smad3 inhibitor SIS3 inhibited approximately 86%, 94%, and 100% of thrombin-induced CCN2 synthesis, respectively. Furthermore, blocking integrin subunits αv and β1 with antibodies effectively inhibited SFLLRN-induced Smad3 phosphorylation and CCN2 synthesis and increased activated TGFβ1 levels; however, similar effects were not observed for integrins αvβ3 and αvβ5. These results suggest that protease-activated receptor 1-induced CCN2 synthesis in human gingival fibroblasts is mediated through integrin αvβ1-induced latent TGFβ1 activation and subsequent TGFβ1 signaling. Moreover, curcumin dose dependently decreased thrombin-induced activated TGFβ1 levels. Curcumin-inhibited thrombin-induced CCN2 synthesis in human gingival fibroblasts is caused by the suppression of latent TGFβ1 activation.

Abstract
We screened and assessed published cotton simple sequence repeat (SSR) primers to establish a set of core SSR markers suitable for cotton major cultivars in China and analyzed genetic diversity based on the core marker set. Using a stepwise screening strategy, 12 leading cultivars for preliminary screening and 96 cultivars for rescreening were evaluated. A total of 184 polymorphic SSR markers were initially screened from 3299 candidates, and a core set of 52 SSR markers with wide genome coverage (2 markers per chromosome) was obtained. Among 96 major cultivars, 273 amplification genotypes were generated using the core marker set. Polymorphism information content values ranged from 0.28-0.83, with an average value of 0.56. The core SSR marker set detected on denaturing polyacrylamide gel electrophoresis indicated that the band genotype was either a single or double band on conventional cultivars, while most were double bands (65.4%). Among 56 hybrids, the average heterozygosis rate was 35.8%, ranging from 7.1-55.4%. Eighteen of 96 cultivars had distinct band genotypes. The genetic diversity analyzed using the of NTSYS-pc V2.10 software indicated that the Yangtze River valley cotton region had the highest polymorphic level, followed by Xinjiang and then the Yellow River valley. The genetic basis of conventional cultivars was narrower than that of hybrids. The core marker set can be used for fingerprint construction, variety identification, and purity tests of major cotton cultivars in China.

Abstract
The aim of this study was to determine whether monocyte/macrophage β2-AR could act as the therapeutic target of antisympathetic excitation-induced atherosclerotic progression. Cultivated human THP-1 cells were divided into different groups and incubated with isoprenaline, metoprolol, propranolol or β2-AR blocker for 24 h, together with oxidized low-density lipoprotein (ox-LDL). Afterwards, each group was analyzed for C-C chemokine receptor type 2 (CCR2) expression, monocyte chemotactic protein 1 (MCP-1) release into medium and cell migration ability. In the isoprenaline group, CCR2 protein level was increased, as well as the secretion of MCP-1, and cell motility was enhanced, in a concentration-dependent manner. Propranolol and ICI 118,551 significantly reversed the stimulatory effect of isoprenaline on THP-1 cells induced by ox-LDL, but only high concentrations of metoprolol interfered significantly with the action of isoprenaline (P < 0.05). Isoprenaline or a β-AR blocker could mediate through β2-AR, affecting MCP-1 secretion, CCR2 protein expression and cell migration capacity of THP-1 cells. Therefore, monocyte-macrophage β2-AR may act as a target of antisympathetic excitation-induced atherosclerotic progression.
