Simple Summary: Computed tomography angiography can provide sufficient information for the diagnosis of acute aortic syndromes. However, non-contrast computed tomography images in the emergency department, compared with CTA, are more easily accessible and convenient and have lower radiation doses with fewer contraindications. We retrospectively analyzed 325 patients' non-contrast CT images from 2 independent medical centers and established an acute aortic syndrome recognition model based on the radiological features of non-contrast CT images through feature extraction and screening. This model can effectively detect acute aortic syndrome on non-contrast CT images with high sensitivity, AUC, and robustness. More importantly, it can diagnose patients who do not have specific imaging findings on non-contrast CT images. It has important clinical applications for the screening of acute aortic syndrome, especially in the emergency department. We aimed to detect acute aortic syndromes (AAS) on non-contrast computed tomography (NCCT) images using a radiomics-based machine learning model. A total of 325 patients who underwent aortic CT angiography (CTA) were enrolled retrospectively from 2 medical centers in China to form the internal cohort (230 patients, 60 patients with AAS) and the external testing cohort (95 patients with AAS). The internal cohort was divided into the training cohort (n = 135), validation cohort (n = 49), and internal testing cohort (n = 46). The aortic mask was manually delineated on NCCT by a radiologist. Least Absolute Shrinkage and Selection Operator regression (LASSO) was used to filter out nine feature parameters; the Support Vector Machine (SVM) model showed the best performance. In the training and validation cohorts, the SVM model had an area under the curve (AUC) of 0.993 (95% CI, 0.965–1); accuracy (ACC), 0.946 (95% CI, 0.877–1); sensitivity, 0.9 (95% CI, 0.696–1); and specificity, 0.964 (95% CI, 0.903–1). In the internal testing cohort, the SVM model had an AUC of 0.997 (95% CI, 0.992–1); ACC, 0.957 (95% CI, 0.945–0.988); sensitivity, 0.889 (95% CI, 0.888–0.889); and specificity, 0.973 (95% CI, 0.959–1). In the external testing cohort, the ACC was 0.991 (95% CI, 0.937–1). This model can detect AAS on NCCT, reducing misdiagnosis and improving examinations and prognosis. [ABSTRACT FROM AUTHOR]

Cotton is the main economic crop in China and is important owing to its use as an industrial raw material and a cash crop. This experiment was conducted in the main cotton-producing area of Xinjiang, China. A hyperspectrometer was used to monitor the canopy spectral reflectance of cotton at different stages of growth. The results showed that the leaf area index (LAI) increased with the increase in the amount of nitrogen fertilizer added during the early full boll stage and decreased with the increase in nitrogen fertilization in the full and late boll stages. Insufficient or excessive fertilization led to a decrease in the LAI. The visible light band indicated that the canopy spectral reflectance decreased, and the amount of fertilizer increased in all the growth stages. The near-infrared band revealed that the canopy spectral reflectance increased with the amount of nitrogen applied during the bud stage, early boll stage, and the most vigorous period of boll growth. During the flowering period, the spectral reflectance followed the order N3 > N4 > N2 > N1 > N0. During the entire growth period of cotton, the values of the cotton LAI predicted using the ratio vegetation index (RVI) model were found to best fit the measured values. The LAI monitoring models of cotton in each growth stage were different. The TVI model is the best in the bud and early boll stages. The NDVI model is the best in the flowering stage, and the DVI model is the best in the full boll stage. This study provides a basis to accurately monitor the LAI in each growth period of cotton.

Although the personality traits (PT), patient-reported outcome (PRO), and chronic prostatitis (CP) symptoms in premature ejaculation (PE) have been evaluated, there was no study to assess their correlations in men with different PE syndromes. The purpose of this study was to assess the correlations between the PT, PRO, and CP symptoms in men with different PE syndromes. Between January 2019 and January 2021, a cross-sectional field study was conducted in our andrology clinic. Men with the complaints of PE were divided into lifelong PE (LPE), acquired PE (APE), variable PE (VPE), and subjective PE (SPE). All subjects were required to complete a verbal questionnaire with the PRO, National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), and Temperament and Character Inventory (TCI-R). Finally, 479 men with the complaints of PE and 365 without the complaints of PE were enrolled. The incidence of PE syndromes in PE complaint group was as follows: LPE 16.70%, APE 48.85%, VPE 11.27%, and SPE 23.17%. Mean ages in PE complaint group were 42.53 ± 12.25 years. In the PE complaint group, the novelty seeking (NS) scores were strongest correlated with the personal distress and quality of life (QOL). The harm avoidance (HA) scores were strongest correlated with the severity of PE and pain syndromes. The self-transcendence (ST) scores were strongest correlated with the satisfaction with sexual intercourse and QOL. In addition, strongest association between the total scores of NIH-CPSI and the NS or ST scores was also found in the APE group. The HA scores were also strongest correlated with the total scores of NIH-CPSI in SPE. Strongest association between the total scores of NIH-CPSI and the NS/TI or ST/CI scores was also found in the APE group. The HA/TI scores were also strongest correlated with the total scores of NIH-CPSI in SPE. [ABSTRACT FROM AUTHOR]

This research qualitatively explored user preferences for an app-based mHealth approach to support HIV self-testing and linkage to HIV prevention or care services developed for men who have sex with men (MSM) in China. We conducted 12 online focus group discussions with MSM participants (N = 48) about their preferences for using an app to meet their HIV self-testing and service linkage needs. Data were examined using thematic analysis. Participants specified four domains to align program delivery with their preferences for app-based intervention: (1) expanding HIV prevention/antiretroviral therapy concepts beyond basic knowledge; (2) enhancing the style and presentation of app-based messages; (3) incorporating interactive and dynamic app-engagement features; and (4) creating a "one station" app that covers the continuum of HIV services. Given the changing landscapes of HIV knowledge and community/user preferences for app-based interaction, findings underscore how engagement with end-user participants is essential to optimize mHealth interventions for HIV.

It is an interesting clinical phenomenon that when evaluating the erectile function of men with erectile dysfunction by couples, respectively, using the erectile hardness model, there will exist the evaluation difference between men and their female partners. This phenomenon reflects the problem of communication and cognition between husband and wife in ED patients. To explore the influencing factors associated with this clinical phenomenon, we conducted this interesting, observational, and cross-sectional field survey. We enrolled 385 couples from the andrology clinics of the first affiliated hospital of Anhui Medical University from December 2017 to December 2018. The demographic data of couples, the medical history, sexuality and the characteristics of ED, and anxiety and depression of the couples were collected through face-to-face interview and questionnaires. The couples were divided into two groups containing 238 couples and 147 couples, respectively. We divided couples into difference group including couples which have inconsistent evaluation results from touching the erectile hardness model and no difference group including couples which have consistent evaluation results from touching the erectile hardness model, respectively. The difference group where the couples share different evaluation results reported higher erectile hardness grade from men than from their female partners (male > female: 73.11% vs. male < female: 26.89%). The scores of IIEF-5 in difference group and no difference group are 13.43 ± 5.75 and 16.82 ± 8.23, respectively. The average grades evaluated from men and women in difference group are 2.79 ± 0.85 and 2.45 ± 0.63, respectively. The average grades evaluated from couples in no difference group are 3.02 ± 0.45. Through statistical comparison and logistic regression analysis, duration of ED > 16 months, seeking treatment from female, negative communication state, and depression from men are the relevant factors accounting for the different evaluation results. This phenomenon reflects the problem of communication and cognition between husband and wife in ED patients. As for couples with these risk factors, we cannot focus only on the oral medication which only restores the penile erectile function. More importantly, we must combine the sexual counseling and sexual knowledge education with the drug treatment. When the two treatments are tightly integrated, not only the penile erection but also the gap of couples can be restored which is the best result of the ED treatment. [ABSTRACT FROM AUTHOR]

Background: Death anxiety is a common phenomenon in all societies. Older adults may be more prone to death anxiety than their younger counterparts; however, death anxiety among older adults is not well understood. This study explores the relationship between meaning in life, self-esteem, and death anxiety in senior citizens in China.Methods: A total of 283 older adults participated in this study; data were collected via the Meaning in Life Questionnaire, the Rosenberg Self-Esteem Scale, and the Death Anxiety Scale.Results: Results show that the dimensions of meaning in life, presence of meaning (r = - 0.43, p < 0.01), search for meaning (r = - 0.31, p < 0.01), and self-esteem (r = - 0.54, p < 0.01) were each negatively correlated with death anxiety. Regression analysis reveals that meaning in life significantly predicted self-esteem and death anxiety (F = 45.70, p < 0.01; R2 = 0.33). Path analysis indicated that self-esteem either completely or partially mediated the effects of meaning in life on death anxiety in older adults.Conclusions: Overall, meaning in life appears to be significantly correlated with death anxiety in older adults, and self-esteem can mediate this effect.

This study tested a mobile health (mHealth) intervention program entitled WeTest, delivered via the WeChat mobile app, to promote oral HIV self-testing (HIVST) among MSM in Hefei, China. A total of 100 MSM participants enrolled, completed baseline assessment, were randomly assigned to intervention or control, and completed 6-month follow-up surveys. Intervention participants (n = 50) received two oral HIVST kits and access to WeTest, a private WeChat group which provided app-based messages and referrals to health services related to HIV. Control participants (n = 50) received two oral HIVST kits only. All participants received instructions to upload photographic results of their oral HIVST, which were sent to the project counselor via a secure WeChat online portal; immediate contact and referrals were made to any participants who tested HIV-positive. In GEE analyses adjusting for time effects and baseline confounders, intervention participants had significantly higher rates of HIV testing (adjusted rate ratio RR = 1.99, 95% confidence interval (CI) 1.07–3.84) and, in particular, higher rates of testing via oral HIVST (adjusted RR = 2.17, 95% CI 1.08–4.37) compared with the control group. Significant time effects were also found such that all participants, regardless of group allocation, had significantly higher rates of reporting consistent condom use with main partners (adjusted RR = 18.13, 95% CI 5.19–63.31) and with non-main partners (adjusted RR = 5.33, 95% CI 2.35–12.08). Findings from this study provide evidence for the feasibility, acceptability and preliminary effects of this mHealth approach to promoting oral HIVST among MSM in China. [ABSTRACT FROM AUTHOR]

Background: Medical disputes remain unabated in China. Previous studies have shown the changes of diagnostic discrepancy over time in developed countries, but diagnostic discrepancy remains understudied in China, especially in the setting of medical disputes. We sought to describe the year-based changes of diagnostic discrepancies in medical disputes, and to identify factors associated with classes of diagnostic discrepancy. Methods: We conducted a retrospective cohort study of all medically disputed cases from 1990 through 2015 in Shanghai, China, with use of necropsy as the gold standard for diagnosis. Cases were grouped based on national legislative eras. Diagnostic discrepancy was classified as major errors (class I and II), minor errors (class III and IV), no discrepancy (class V) and undetermined (class VI) based on discrepancy severity. Results: There were 482 medical disputes. Cases were predominantly males (male: female = 1.6:1) and concentrated in patients less than 10 years old or between 50 and 70 years. Major and minor discrepancy accounted for 51.7 and 34.8%, respectively. Fifty-five cases (11.2%) were non-discrepant (Class V). The dispute rate remained high before the first round of legislation (mean 0.31 per 1 million patients) but declined dramatically afterwards (R2 = − 0.82, p < 0.001 for time trends). Over the national legislative eras, the annual number of cases with diagnostic errors declined steadily. Incidence rates of discrepancy decreased significantly for class I (R2 = − 0.73, p = 0.024), II (R2 = − 0.48, p = 0.013), III (R2 = − 0.69, p < 0.0001), IV (R2 = − 0.69, p < 0.0001) and V discrepancy (R2 = − 0.58, p = 0.0018). Diseases from the respiratory system had significantly lower risks of any diagnostic errors (OR = 0.48, 95% 0.24–0.95, p = 0.036). A neoplasm carrier increased by 92% the risk of any diagnostic error (OR = 1.92; 95%CI 1.18–3.14; p = 0.009) and hypertension reduced by 78% the risk of minor errors (OR = 0.22, 95%CI 0.06–0.91, p = 0.036). Severity of discrepancy relieved over years and associated with ageing in patients with cardiovascular diseases (p = 0.01). Conclusions: The rate of fatal medical disputes and diagnostic discrepancy declined after stepwise legislations in China. Respiratory diseases, neoplasm carrier and hypertension could be independent predictors for assessing diagnostic errors. [ABSTRACT FROM AUTHOR]

[Display omitted] • The impact of coupled multi-dimensional environmental factors on solar greenhouse temperature was considered. • The proposed novel FAM-LSTM model fuses feed-forward attention mechanism and LSTM model. • The FAM enhanced the accuracy of multistep time series prediction. • The FAM-LSTM model had a superior prediction performance. Solar greenhouses offer favorable climatic environments for the production of off-season crops in northern China. Greenhouse temperature and humidity are critical environmental factors influencing crop growth; therefore, it is crucial to predict the temperature and humidity. In this research, we constructed a feed-forward attention mechanism- long-short term memory (FAM-LSTM) model for the multistep prediction of temperature and humidity in a solar greenhouse. The FAM-LSTM model considered both internal and external environmental factors influencing crop growth, where the factors include temperature, humidity, light, soil temperature, and soil moisture. Then, we performed corresponding experiments employing this model in predicting both temperature and humidity at prediction horizons of 12, 24, 36, and 48 h. The FAM-LSTM model stands out due to its high accuracy compared with different models. The temperature prediction error of the model at four prediction horizons is primarily within [−0.5, 0.9], [−2.1, 1.7], [−0.9, 2.7], and [−1.8, 2.9] ℃, respectively. The humidity prediction errors of the model at four prediction horizons are mainly within [−1.9, 1.8], [−4.4, 3.6], [−6.9, 2.4], and [−5.8, 4.4] %, respectively. This study offers an effective temperature and humidity prediction approach for precise environmental regulation and damage warnings in solar greenhouses. [ABSTRACT FROM AUTHOR]

The purpose of this study is to investigate the effects of adult male circumcision on premature ejaculation (PE). Therefore, between December 2009 and March 2014, a total of 575 circumcised men and 623 uncircumcised men (control group) were evaluated. Detailed evaluations (including circumcision and control groups) on PE were conducted before circumcision and at the 3-, 6-, 9-, and 12-month follow-up visits after circumcision. Self-estimated intravaginal ejaculatory latency time (IELT), Patient-Reported Outcome measures, and 5-item version of the International Index of Erectile Function were used to measure the ejaculatory and erectile function for all subjects. The results showed that, during the one-year follow-up, men after circumcision experienced higher IELT and better scores of control over ejaculation, satisfaction with sexual intercourse, and severity of PE than men before circumcision (P<0.001 for all). Similarly, when compared with the control group, the circumcised men reported significantly improved IELT, control over ejaculation, and satisfaction with sexual intercourse (P<0.001 for all). These findings suggested that circumcision might have positive effects on IELT, ejaculatory control, sexual satisfaction, and PE severity. In addition, circumcision was significantly associated with the development of PE. [ABSTRACT FROM AUTHOR]

Overall, total exhaust emissions of NO X , VOC and particulate matter (PM) declined, though vehicles in use continued to increase in China. This suggested that contribution of motor vehicle exhaust to haze in China may be exaggerated. A higher frequency of haze episodes in China with lower total emissions fraction from vehicle exhaust compared with those in the USA confirmed that there exists no strict causality between vehicle and haze. No significant correlation ( p < 0.05) between haze days and the contribution of vehicles to airborne PM 2.5 (particulates that are < 2.5 μm in aerodynamic diameter) or car ownerships. All results revealed again that vehicle exhaust is an overstated cause for haze formation in China. [ABSTRACT FROM AUTHOR]

Background: HIV self-testing (HIVST) has demonstrated potential to expand HIV testing among key populations, including men who have sex with men (MSM) in China who have low testing rates. However, due to the autonomous nature of self-testing, people who undergo HIVST may lack access to relevant information and counseling support typically provided by in-person HIV testing counselors. WeChat, a popular smartphone application in China, offers a potential source of mobile health (mHealth) information and support for individuals using HIVST. This paper aimed to explore the opinions of MSM in China about the feasibility and potential concerns of using WeChat to support HIVST and reduce risk for HIV infection.Methods: We conducted in-depth interviews with 36 MSM about their mobile smartphone usage and the use of WeChat for helping MSM self-administer HIVST kits in Hefei, China. Each interview was digitally recorded and transcribed. Transcripts were analyzed used content analysis method according to Elo and Kyngas.Results: MSM described their use of WeChat and expressed cautious endorsement about using this platform to promote HIVST and disseminate HIV-related information. They described their preferences about the implementation features of an mHealth intervention to promote HIVST, including the delivery source of intervention messages, as well as message timing, frequency, form, tone, and content. Participants also described privacy-related concerns about receiving messages via WeChat and offered potential solutions.Conclusions: Findings from this study show the potential utility of WeChat app-based messaging for engaging MSM in HIV self-testing and prevention. Future research is needed to integrate the concerns expressed in this analysis and evaluate a WeChat-based intervention to promote oral HIV self-testing, risk reduction, and health promotion among MSM in China.

In contrast with its decrease in western China deserts, the dust storm event in eastern China, Korea, and Japan shows an increase in frequency. Although the drylands in northeastern China have been recognized as an important dust source, the relative contributions of dust transport from the drylands and deserts are inconclusive, thus the quantification of dust storm sources in downwind area remains a challenge. We measured the 14 C and 13 C contents in carbonates of dust samples from six sites in China, which were collected for the duration of dust storm events in drylands, deserts, and urban areas. The δ 13 C of the dryland dust samples considerably varied in a range of − 9.7 to − 5.0‰, which partly overlapped the desert dust carbonate δ 13 C ranges. The 14 C content of the dryland dust carbonates showed a narrow range of 60.9 ± 4.0 (as an average and 1 SD of five samples) percent modern carbon (pMC), indicating the enrichment of modern carbonate. Dust samples in desert regions contained relatively aged carbonates with the depleting 14 C showing of 28.8 ± 3.3 pMC. After the long-range transport of the western China desert dust plume, the carbonates collected at the southern China remained the depletion of 14 C (33.5 ± 5.3 pMC) as in the desert regions. On the other hand, the samples of dust storm events at the urban areas of eastern China showed an enrichment of 14 C contents (46.2 ± 5.0 pMC, n = 7), which might be explained by the stronger contribution of modern-carbonate-rich dryland dust.

Introduction Some factors associated with the four premature ejaculation ( PE) syndromes have been studied, but the association between International Prostate Symptom Score ( IPSS) and the four PE syndromes has not been investigated. Aims We performed this study to evaluate the association between IPSS and intravaginal ejaculatory latency time ( IELT) in men with the four PE syndromes. Methods From June 2012 to January 2014, a total of 690 men aged 40-59 years complaining of ejaculating prematurely and another 452 male healthy subjects of the same age without these complaints were included in this study. Men with the complaints of ejaculating prematurely were classified as one of the four PE syndromes: lifelong PE, acquired PE ( APE), variable PE, and subjective PE. Each of them completed a detailed questionnaire including information on demographics, medical and sexual history (e.g., self-estimated IELT), IPSS, and International Index of Erectile Function-5. Main Outcome Measures Associations between IPSS and self-estimated IELT in middle-aged men with the four PE syndromes. Results Men complaining of ejaculating prematurely reported higher IPSS (11.2 ± 6.0 vs. 5.5 ± 3.3 ) and shorter self-estimated IELT (2.1 ± 1.6 minutes vs. 4.8 ± 3.3) than men without complaints ( P < 0.001 for each). By unilabiate analysis, self-estimated IELT in men with the four PE syndromes showed significant correlations with IPSS ( P < 0.001 for all). After adjusting for age, self-estimated IELT was negatively associated with IPSS in men with PE complaints (adjusted r = −0.378, P < 0.001). Also, the association was stronger in men with APE (adjusted r = −0.502, P < 0.001). Conclusions Men complaining of ejaculating prematurely reported worse IPSS than men without these complaints. Self-estimated IELT was negatively associated with IPSS in men complaining of ejaculating prematurely, and the correlation was the strongest in men with APE.

Introduction A new classification of premature ejaculation ( PE) has been proposed, including the categories of lifelong PE ( LPE), acquired PE ( APE), natural variable PE ( NVPE), and premature-like ejaculatory dysfunction ( PLED). Aim The aim of this study was to evaluate the impact of intravaginal ejaculation latency time ( IELT) and erectile function on anxiety and depression among patients with PE in general and according to the four types of PE. Methods Between September 2011 and September 2012, we conducted a cross-sectional study in the Anhui province of China. We enrolled 4,000 men aged over 18 years, each of whom had been in a stable, monogamous, heterosexual relationship with the same partner for at least 6 months. Main Outcome Measurements Self-estimated IELT, the International Index of Erectile Function-5 ( IIEF-5) and the Zung Self-Rating Anxiety and Depression Scales ( SAS/ SDS) were used to measure PE, erectile dysfunction ( ED), anxiety, and depression, respectively, among the entire study population. Results Of the 3,016 men evaluated, 25.80% complained of PE. Distribution of the four types of PE among men with PE was as follows: LPE, 12.34%; APE, 18.77%; NVPE, 44.09%; PLED, 24.81%. Men with PE presented lower IIEF-5 scores and higher SAS and SDS scores vs. men without PE ( P < 0.001 for all). Similar findings were observed in men with APE when compared with other PE syndromes. After adjustment for age in men with PE, IELT was negatively associated with SAS and SDS scores ( SAS, adjusted r = −0.42, P < 0.001; SDS, adjusted r = −0.45, P < 0.001). IIEF-5 score was negatively associated with SAS and SDS scores ( SAS, adjusted r = −0.54, P < 0.001; SDS, adjusted r = −0.50, P < 0.001). These negative relationships were strongest in men with PLED ( IELT vs. SAS: adjusted r = −0.63, P < 0.001; IELT vs. SDS, adjusted r = −0.60, P < 0.001; IIEF-5 vs. SAS: adjusted r = −0.57, P < 0.001; IELT vs. SDS, adjusted r = −0.55, P < 0.001). Conclusions APE patients reported higher rates of ED, anxiety, and depression than men with other types of PE. The negative relationships between IELT/ IIEF-5 and SAS/ SDS were strongest in men with PLED. Gao J, Zhang X, Su P, Peng Z, Liu J, Xia L, Lu Z, Yang J, Tang D, Gao P, Zhou J, Hao Z, and Liang C.

Abstract: To understand oxygen and carbon stable isotopic characteristics of aragonite stalagmites and evaluate their applicability to paleoclimate, the isotopic compositions of active and fossil aragonite speleothems and water samples from an in situ multi-year (October 2005–July 2010) monitoring program in Furong Cave located in Chongqing of China have been examined. The observations during October 2005–June 2007 show that the meteoric water is well mixed in the overlying 300–500-m bedrock aquifer, reflected by relatively constant δ18O, ±0.11–0.14‰ (1σ), of drip waters in the cave, which represents the annual status of rainfall water. Active cave aragonite speleothems are at oxygen isotopic equilibrium with drip water and their δ18O values capture the surface-water oxygen isotopic signal. Aragonite-to-calcite transformation since the last glaciation is not noticeable in Furong stalagmites. Our multi-year field experiment approves that aragonite stalagmite δ18O records in this cave are suitable for paleoclimate reconstruction. With high U, 0.5–7.2ppm, and low Th, 20–1270ppt, the Furong aragonite stalagmites provide very precise chronology (as good as ±20s yrs (2σ)) of the climatic variations since the last deglaciation. The synchroneity of Chinese stalagmite δ18O records at the transition into the Bølling–Allerød (t-BA) and the Younger Dryas from Furong, Hulu and Dongge Caves supports the fidelity of the reconstructed East Asian monsoon evolution. However, the Furong record shows that the cold Older Dryas (OD) occurred at 14.0 thousand years ago, agreeing with Greenland ice core δ18O records but ∼200yrs younger than that in the Hulu record. The OD age discrepancy between Chinese caves can be attributable to different regionally climatic/environmental conditions or chronological uncertainty of stalagmite proxy records, which is limited by changes in growth rate and subsampling intervals in absolute dating. Seasonal dissolved inorganic carbon δ13C variations of 2–3‰ in the drip water and 5–7‰ in the pool and spring waters are likely attributed to variable degrees of CO2 degassing in winter and summer. The variable δ13C values of active deposits from −11‰ to 0‰ could be caused by kinetically mediated CO2 degassing processes. The complicated nature of pre-deposition kinetic isotopic fractionation processes for carbon isotopes in speleothems at Furong Cave require further study before they can be interpreted in a paleoclimatic or paleoenvironmental context.

Background: Since the outbreak of coronavirus disease 2019, it has had a serious impact on people's physical and mental health. However, in our clinical work, we have found that the erectile function of coronavirus disease 2019 patients with neurological decline was often seriously affected., Objectives: To further explore the relationship between erectile dysfunction and neurological dysfunction caused by coronavirus disease 2019., Materials and Methods: We conducted a survey from August 2022 to February 2023 at the First Affiliated Hospital of Anhui Medical University and the Third People's Hospital of Linyi City. A total of 251 subjects with a history of coronavirus disease 2019 infection were included. Symptoms and changes in erectile function after the coronavirus disease 2019 infection were collected and assessed using the International Index of Erectile Function-5 scale and several targeted questions., Results: In this study, we found that in patients infected with novel coronavirus, the proportion of erectile dysfunction was higher in those with neurological manifestations such as olfactory and taste impairment or psychological symptoms such as anxiety., Discussion: We found that neurological decline and psychological factors were independent and significant risk factors for erectile dysfunction caused by coronavirus disease 2019., Conclusion: Patients with neurological damage or psychiatric symptoms are more likely to have erectile dysfunction, suggesting that the 2019 novel coronavirus may affect erectile function by damaging nerves. This provides a new insight into the mechanism of erectile dysfunction., (© 2024 American Society of Andrology and European Academy of Andrology.)

Objective: Achieving textbook outcome (TO) implies a smooth recovery post-operation without specified composite complications. This study aimed to evaluate TO in laparoscopic pancreaticoduodenectomy (LPD) and identify independent risk factors associated with achieving TO., Methods: We conducted a retrospective analysis of data from a randomized controlled trial on LPD at West China Hospital (ChiCTR1900026653). Patients were categorized into the TO and non-TO groups. Perioperative variables were compared between these groups. Multivariate logistic regression was utilized to identify the risk factors., Results: A total of 200 consecutive patients undergoing LPD were included in this study. TO was achieved in 82.5% (n = 165) of the patients. Female patients (OR: 2.877, 95% CI: 1.219-6.790; P = 0.016) and those with a hard pancreatic texture (OR: 2.435, 95% CI: 1.018-5.827; P = 0.046) were associated with an increased likelihood of achieving TO., Conclusions: TO can be achieved in more than 80% of patients in a high-volume LPD center. Independent risk factors associated with achieving TO included gender (male) and pancreatic texture (soft)., (© 2024. The Author(s).)

Objective: Shift work and Shift Work Sleep Disorder (SWSD) are known to affect the secretion of several neurotransmitters and hormones associated with premature ejaculation (PE). However, their specific influence on the regulation of male ejaculation remains unclear. This study explores the relationship between shift work, SWSD, and PE., Methods: From April to October 2023, a cross-sectional survey was conducted across five regions of China to explore the work schedules, sleep quality, and sexual function of male workers. Participants' sleep quality was evaluated using a validated SWSD questionnaire, and their erectile function and ejaculatory control were assessed with the International Inventory of Erectile Function (IIEF-5) scores and Premature Ejaculation Diagnostic Tool (PEDT) scores, respectively. Univariate and multivariate linear regression analyses were employed to identify risk factors associated with PE. Confounders were controlled using multiple regression models, and clinical prediction models were developed to predict PE onset and assess the contribution of risk factors., Results: The study included 1239 eligible participants, comprising 840 non-shift workers and 399 shift workers (148 with SWSD and 251 without SWSD). Compared to non-shift working males, those involved in shift work (β 1.58, 95% CI 0.75 - 2.42, p < 0.001) and those suffering from SWSD (β 2.86, 95% CI 1.86 - 3.85, p < 0.001) they had significantly higher PEDT scores. Additionally, we identified daily sleep of less than six hours, depression, anxiety, diabetes, hyperlipidemia, frequent alcohol consumption (more than twice a week), and erectile dysfunction as risk factors for PE. The predictive model for PE demonstrated commendable efficacy., Conclusion: Both shift work and SWSD significantly increase the risk of premature ejaculation, with the risk magnifying in tandem with the duration of shift work. This study reveals the potential impact of shift work and SWSD on PE and provides new theoretical foundations for the risk assessment and prevention of this condition., (© 2024. The Author(s).)

Background: Men who have sex with men (MSM) in China have a high risk for HIV infection but experience suboptimal rates of HIV testing and service engagement due to various social and structural barriers. We developed a mobile health (mHealth) intervention entitled "WeTest-Plus" (WeTest+) as a user-centered "one-stop service" approach for delivering access to comprehensive information about HIV risk, HIV self-testing, behavioral and biomedical prevention, confirmatory testing, treatment, and care., Objective: The goal of the current study was to investigate the feasibility of WeTest+ to provide continuous HIV services to high-risk MSM., Methods: Participants completed a 3-week pilot test of WeTest+ to examine acceptability, feasibility, and recommendations for improvement. Participants completed a structured online questionnaire and qualitative exit interviews facilitated by project staff. "Click-through" rates were assessed to examine engagement with online content., Results: 28 participants were included, and the average age was 27.6 years (standard deviation = 6.8). Almost all participants (96.4%) remained engaged with the WeTest+ program over a 3-week observational period. The majority (92.9%) self-administered the HIV self-test and submitted their test results through the online platform. Overall click-through rates were high (average 67.9%). Participants provided favorable comments about the quality and relevance of the WeTest+ information content, the engaging style of information presentation, and the user-centered features., Conclusion: This pilot assessment of WeTest+ supports the promise of this program for promoting HIV self-testing and linkage to in-person services for MSM in China. Findings underscore the utility of a user-centered approach to mHealth program design., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background: Chondrosarcoma (CHS) is highly prone to recurrence and has become the most common malignant bone tumor in adults. The authors aim to identify and analyze the top 100 most-cited articles in this field, enabling researchers to quickly grasp the research focus and progress in the area of chondrosarcoma recurrence., Methods: A search in the Web of Science database yielded a total of 305 articles related to CHS recurrence between 2013 and 2022. Filtering was done based on the titles and abstracts of the articles in the list, and the top 100 most-cited articles were selected. The following information were analyzed using bibliometric methods: article title, first author, year of publication, journal of publication, total citations, country, institution, and keywords., Results: Among the selected 100 articles, the most frequently cited one has 224 citations. The most commonly appearing journals, institutions, and countries are as follows: "Clinical Orthopaedics Related Research" (5 times); Fudan University, University of Texas System, and Royal Orthopaedic Hospital (4 times each), with China and the USA cited the most (21 times each). The year 2018 is the most productive year (17 articles). About 97 first authors contributed one article each, and 3 had 2 articles each. Among all 229 keywords, the top 3 in frequency are CHS (20%), recurrence (4%), and surgery (3%). Twenty article topics are related to surgical treatment., Conclusion: Research on CHS recurrence is citation-rich but focuses more on treatments than understanding mechanisms, indicating a need for deeper mechanistic exploration for treatment breakthroughs in the future., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2023 the Author(s).

Traffic emissions and waste incineration are the main sources of PAHs in urban atmosphere, but their spatially superimposed effects are currently unclear. This study assessed the spatial distribution of PAHs and HPAHs concentrations in the atmosphere of Shenzhen by simulating the spatial and temporal dispersion of PAHs and HPAHs emissions from on-road vehicles and municipal solid waste incinerators (MSWIs). Generally, the concentrations of PAHs and HPAHs were higher on workdays than on weekends due to higher traffic volumes, while the prevailing wind direction of the northeast could cause more widespread dispersion of PAHs and HPAHs within Shenzhen's atmosphere. After superimposing the spatial distribution of pollutants emitted by vehicles and MSWIs, PAHs within 1000 m downwind of MSWIs are mainly contributed by MSWIs and beyond 1000 m by vehicles. The cancer risk values induced by exposure to PAHs and HPAHs via inhalation in Shenzhen were below the acceptable risk level for males and females in each age group, while adults faced the highest cancer risk, followed by adolescents and children. However, spatially, the cancer risk values were above the priority risk level for adult males in localized high-traffic areas in Futian and Luohu districts., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 The Authors.

Carbonaceous aerosols are major components in PM 2.5 of both polluted and clean atmosphere. Accurate source apportionment of carbonaceous aerosols may support effective PM 2.5 control. Dual-carbon isotope method ( 14 C and 13 C) was adopted to identify the contribution of three main air pollution sources biogenic and biomass (f bb ), liquid fossil (f liq.fossil ) and coal (f coal ). The aerosol samples were collected at three types of sites with distinctly different degree of air pollution: urban, rural and regional background. The seasonal variation of source apportionment of the carbonaceous aerosols in urban Beijing was discussed. Modern biogenic and biomass made an absolute dominance of 92.9 ± 0.5% contribution to the carbonaceous aerosols at the background site Mt. Yulong due to long-range transport from Southeast Asia. The three main sources contributed jointly to the atmospheric carbonaceous aerosols at the rural site Wangdu and the urban site Beijing. The biogenic and biomass source was the major contribution in summer (47.0 ± 0.3%) and autumn (49.3 ± 0.3%) of Beijing, while coal source increased from summer (26.8 ± 13.8%) to autumn (34.7 ± 11.5%). Heating significantly increased the coal source to the dominant contribution (47.0 ± 16.9%) in winter of Beijing. Separate day and night time coal contributions were used to evaluate the two origins of coal combustion: industrial use vs. residential use. The results of source apportionment for carbonaceous aerosols provide scientific support for the prevention and control of air pollution., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier B.V.

This study was to explore whether serotonin transporter gene-linked polymorphic region polymorphisms (5-HTTLPR+rs25531) influence the response to dapoxetine treatment in a Chinese population with premature ejaculation (PE). 112 patients with PE re-enrolled from our previous study received dapoxetine monotherapy. At the endpoint, patients with S'S' had a significant increased risk of nonresponse compared with L' carriers (p < .001). The improvement in S'S' genotype was significantly lower in premature ejaculation profile (PEP) items of 'control over ejaculation' (p = .035) and 'distress related to ejaculation' (p = .017) than that in L' carriers. As to clinical global impression of change (CGIC), results in S'S' subjects showed significantly lower scores (p = .008) and a less satisfaction rate reporting at least 'better' (p = .020) compared with L' carriers. Moreover, our findings suggested that patients with S'S' were more likely to develop adverse effects (AEs) compared with L' carriers (p = .040). This study suggests that PE patients bearing the S'S' genotype have an inferior comprehensive efficacy and safety of dapoxetine treatment, which consist of poorer response in IELTs, less improvement in patient-reported outcome (PRO) measures and greater incidence of AEs, than L' carriers. Variants of triallelic 5-HTTLPR may play a major role as a predictor of treatment response to dapoxetine., (© 2021 Wiley-VCH GmbH.)

The aim of the study was to investigate the chemical properties of the most popular commercial extra virgin olive oils (EVOOs) in China. A total of 14 EVOO samples were collected and evaluated, and significant differences were observed with respect to physicochemical properties, fatty acid composition, minor components, and the oxidation stability index (OSI). The results showed that the chemical properties of EVOOs were significantly affected by different producing areas. The oleic acid (C18:1) content (average value: 77.80%), squalene content (average value: 6052.28 mg/kg), and OSI (average value: 9.90 h) of the Spanish olive oil were higher than those of the other oils investigated, while the total phenolic content (average value: 308.34 mg/kg) was the lowest. Greek EVOOs had the lowest total sterol content (average value: 1023.48 mg/kg) and OSI (average value: 4.22 h). The C18:1 content (66.42%) and squalene content (3173.42 mg/kg) of the EVOO from China were lower than those of the other oils, while the palmitic acid (C16:0, 16.82%), linoleic acid (C18:2, 12.18%), total phenolic (553.17 mg/kg), and total sterol content (1904.77 mg/kg) were higher than those of the other olive oils. The EVOOs of the various countries could be distinguished by hierarchical cluster analysis (HCA). In addition, multiple linear regression (MLR) analyses between the OSI and chemical properties revealed that squalene (R = 0.729) and the unsaturation determined by the specific UV adsorption at 232 nm (K 232 , R = -0.300) were the main factors to affecting the EVOO oxidation stability.

Background: Laparoscopic pancreaticoduodenectomy (LPD) technique with artificial vascular graft reconstruction for patients with borderline resectable pancreatic cancer has been rarely reported since it is a very challenging technique. However, preliminary experience for the technique has been reported at the Department of Pancreatic Surgery, West China Hospital, Sichuan University.1,2 The rising popularity of neoadjuvant chemotherapy for pancreatic cancer patients may result in the increase of operative difficulty due to tissue edema and many other factors caused by the chemotherapy. The main aim of this study was to demonstrate the feasibility, safety, and key surgical procedure for LPD using video evidence., Methods: A three-dimensional upper abdominal computed tomography angiography (CTA) scan done to a 51-year-old man brought to the center with upper abdominal pain showed a mass in the uncinate process of the pancreas, with over 180-degree involvement of the superior mesenteric vein. Percutaneous transhepatic cholangial drainage (PTCD) was performed to reduce jaundice while endoscopic ultrasound and fine-needle aspiration (EUS-FNA) were done to confirm the diagnosis of adenocarcinoma. The patient underwent two cycles of neoadjuvant chemotherapy using albumin-bound paclitaxel gemcitabine + program. The chemotherapy helped in significantly relieving the symptoms where CA 199 reduced from 586.7 IU/ml to 36.73 IU/ml, and the tumor maximum diameter was reduced from 4.3 cm to 2.2 cm. The violated superior mesenteric vein (SMV) and the tumor were en bloc resected, and a 4.0-cm artificial vascular graft was placed for reconstruction. Bing's anastomosis was performed using pancreaticojejunostomy3 while cholangiojejunostomy was performed using continuous stitching. The gastroduodenal artery (GDA) stump was wrapped with ligamentum teres hepatis after the completion of gastrointestinal anastomosis. The specimen was then removed through the extended umbilical incision (4 cm) and the operation was completed after the drainage tube was placed., Results: The length of intraoperative excisional SMV, duration of artificial vascular graft reconstruction, operation time, and volume of intraoperative blood loss were 4.0 cm, 30 min, 520 min, and 800 mL, respectively. Histopathological examination of ypT2N1 indicated that 1 of the 27 lymph nodes was positive. Pathological results showed a moderately differentiated adenocarcinoma with all margins being negative., Conclusions: This study demonstrated the feasibility of total laparoscopic pancreaticoduodenectomy combined with vascular resection and artificial vascular graft reconstruction in properly selected cases of pancreatic cancer with vein involvement after neoadjuvant chemotherapy. It is worth noting that skilled laparoscopic technicians and effective teamwork are necessities for safe completion of the procedure.

This study compared the lipid compositions, minor components contents, oxidative stability index, and free radical scavenging capacities of walnut oils from two species in China: Juglans regia (common walnut) and Juglans sigillata (iron walnut). The results showed that iron walnut oil contained lower C16:0 (4.97-5.25%) and special fatty acid (erucic acid C22:1). Common walnut oil provided higher tocopherols (441.03-490.32 mg/kg), phytosterols (1014.49-1211.40 mg/kg), squalene (4.41-5.21 mg/kg), and polyphenols (44.78-64.61 mg GAE/kg) and better antioxidant capacities. The walnut oil of the different walnut species could be distinguished by principal component analysis and hierarchical cluster analysis. In addition, multiple linear regression was employed to evaluate the contributions of minor components to the free radical scavenging capacity of the walnut oils and develop a predictive model for the antioxidant capacity of the oil. This information has important implications for the nutritional value and industrial production of walnut oil in China., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Objective: To investigate an association between maternal prenatal exposure to several environmental factors and risk of childhood acute lymphocytic leukemia (ALL), and the possible interactions in the Chinese population., Methods: 345 cases with ALL and their 1:1 age, gender, residence region matched controls aged 0-15 years were recruited from four hospitals in Henan Province from 2014 to 2016. Information was collected by interviews using a questionnaire. Unconditional logistic regression adjusted for age, gender, residence region and relevant confounders was carried out to generate the odds ratios (ORs) and 95% confidence intervals (CIs)., Results: Our data indicate that maternal prenatal exposure to interior housing renovation (adjusted OR: 2.98, 95% CI: 1.51-5.86) or pesticides (adjusted OR: 1.48, 95% CI: 1.67-2.28) increased the risk of childhood ALL. Various subgroup analyses stratified by child's gender, age at diagnosis and other factors also supported these results. However, no interaction was detected between exposure to internal housing renovation and pesticides using an additive model. No significant links between maternal exposures to, environmental tobacco smoking (ETS), antipyretic analgesia intake, or viral infectious diseases with risk of ALL were detected., Conclusion: Findings in our study are in line with the existing literatures, which support the hypothesis that maternal prenatal exposure to interior housing renovation and pesticides are risk factors for childhood ALL. Notably, we found no interaction between these two risk factors, these findings may inform prevention and early detection strategies., (Copyright © 2018 The Authors. Published by Elsevier Ltd..

Objective: This study aimed to establish the first global health bachelor curriculum in China., Design: The Delphi methodology was used to determine expert consensus on which courses should be included in the global health bachelor curriculum. A literature review and a workshop proceeding were performed to generate courses. Then a two-round Delphi process was conducted with 28 invited experts from universities, health administrative departments and non-governmental organisations to rate courses using a 5-point Likert scale. Additionally, the experts could alter, add or delete courses as appropriate. Consensus was predefined as a mean score of 4 or above and the percent agreement (proportion of panel members scoring 'very important' or 'important') no less than 75%., Results: The responses in the two-round Delphi process were 85.7% and 70.8%, respectively. In the first round, 12 courses did not meet the inclusion criteria and were removed. Based on the participants' comments, 32 courses were included in round 2. In the second round, the consensus was reached on 31 courses which were selected as the final curriculum. These courses were categorised into five modules, including General Knowledge, Methodology, Global Health Issues, Intercultural Communication, and Health Policy and Programme Management., Conclusion: This study established the first global health bachelor curriculum in China. It will provide guidance for other educational institutions to develop similar programmes or curricula in the future., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Background: Development assistance for health (DAH) is an important component of foreign assistance. International health consultants usually play a key role in the international DAH field. However, there is still a shortage of consulting training in China. To address this issue and develop new backup force of DAH for China, the Global Health Institute of Wuhan University (GHIWHU) launched a training program called the "Consulting Training Course for International Development Assistance for Health". The purpose of this article is to evaluate the impact of the training on participants., Methods: We conducted the analysis using Kirkpatrick's model. An evaluation survey examining participants' reaction (level 1) and learning (level 2) was carried out among trainees following the training, and a follow-up telephone interview of application (level 3) was made in three months after the training., Results: A total of 25 participants from Chinese Consortium of Universities for Global Health (CCUGH) attended the training program. Results of satisfaction evaluation indicated that the training program was well received, with more than 85% of participants felt satisfied or relatively satisfied with the training. Trainees' self-ratings of the consulting knowledge and skills showed a significant increase (p < 0.001) from pre- to post-training. The follow-up interview revealed that the majority of participants applied the acquired knowledge and skills under various circumstances such as consulting program, teaching processes, writing reports, and et al. Meanwhile, participants considered that the lack of opportunities was one of the major application barriers. In addition, they expressed the willingness to participate in more relevant training and the need for more practice opportunities., Conclusions: This is the first study evaluating a consulting training program in China. The results show that the training course has been successfully implemented and participants have been given consulting knowledge and skills. Future research should use better-designed training methods based on demand surveys and consider providing participants with practice or practicum opportunities. Also, it is necessary to conduct both primary and advanced training courses and evaluate participants' long-term behavior changes resulting from the training.

Objective: The aim of this study was to investigate the relationship between number of circulating T cells and coronary artery disease (CAD) in an elderly Chinese population., Methods: A total of 295 elderly inpatients (age≥60) were included in this cross-sectional study. Their clinical and biochemical characteristics were recorded. Patients were divided to two groups: control patients and CAD patients. The risk factors of CAD were explored by binary logistic regression analysis., Results: Compared with control patients, the ratio of CD4 to CD8 T cells was significantly increased in CAD patients. There was no difference in the number of CD3, CD4, and CD8 T cells between the two groups. Multiple logistic regression analysis showed that CAD was independently associated with age, gender, body mass index (BMI), systolic blood pressure (SBP), chronic heart failure (CHF) and the CD4/CD8 ratio. In addition, after adjusting for different clinical parameters (including gender, age, CHF, hypertension, arrhythmia, SBP, and BMI), the risk of CAD was significantly increased in patients with a CD4/CD8 ratio>1.5., Conclusions: There was a strong and independent association between the ratio of CD4/CD8 and CAD in elderly Chinese population., (Copyright © 2016.

BACKGROUND The STin2 VNTR polymorphism has a variable number of tandem repeats in intron 2 of the serotonin transporter gene. We aimed to explore the relationship between STin2 VNTR polymorphism and lifelong premature ejaculation (LPE). MATERIAL AND METHODS We recruited a total of 115 outpatients who complained of ejaculating prematurely and who were diagnosed as LPE, and 101 controls without PE complaint. Allelic variations of STin2 VNTR were genotyped using PCR-based technology. We evaluated the associations between STin2 VNTR allelic and genotypic frequencies and LPE, as well as the intravaginal ejaculation latency time (IELT) of different STin2 VNTR genotypes among LPE patients. RESULTS The patients and controls did not differ significantly in terms of any characteristic except age. A significantly higher frequency of STin2.12/12 genotype was found among LPE patients versus controls (P=0.026). Frequency of patients carrying at least 1 copy of the 10-repeat allele was significantly lower compared to the control group (28.3% vs. 41.8%, OR=0.55; 95%CI=0.31-0.97, P=0.040). In the LPE group, the mean IELT showed significant difference in STin2.12/12 genotype when compared to those with STin2.12/10 and STin2.10/10 genotypes. The mean IELT in10-repeat allele carriers was 50% longer compared to homozygous carriers of the STin2.12 allele. CONCLUSIONS Our results indicate the presence of STin2.10 allele is a protective factor for LPE. Men carrying the higher expression genotype STin2. 12/12 have shorter IELT than 10-repeat allele carriers., Competing Interests: There are no conflicts of interests to disclose.

BACKGROUND This study aimed to explore the relationship between premature ejaculation (PE) and the serotonin transporter gene-linked polymorphic region (5-HTTLPR) with respect to the biallelic and triallelic classifications. MATERIAL AND METHODS A total of 115 outpatients who complained of ejaculating prematurely and who were diagnosed as having lifelong premature ejaculation (LPE) and 101 controls without PE complaint were recruited. All subjects completed a detailed questionnaire and were genotyped for 5-HTTLPR polymorphism using PCR-based technology. We evaluated the associations between 5-HTTLPR allelic and genotypic frequencies and their association with LPE, as well as the intravaginal ejaculation latency time (IELT) of different 5-HTTLPR genotypes among LPE patients. RESULTS The patients and controls did not differ significantly in terms of any characteristic except age. The results showed no significant difference regarding biallelic 5-HTTLPR. According to the triallelic classification, no significant difference was found when comparing the genotypic distribution (P=0.091). However, the distribution of the S, LG, and LA alleles in the cases was significantly different from the controls (P=0.018). We found a significantly lower frequency of LA allele and higher frequency of LG allele in patients. Based on another classification by expression, we found a significantly lower frequency of the L'L' genotype (OR=0.37; 95%CI=0.15-0.91, P=0.025) in patients with LPE. No significant association was detected between IELT of LPE and different genotypes. CONCLUSIONS Contrary to the general classification based on S/L alleles, triallelic 5-HTTLPR was associated with LPE. Triallelic 5-HTTLPR may be a promising field for genetic research in PE to avoid false-negative results in future studies.

The purpose of the study is to evaluate the relationship between NIH-CPSI and IIEF-5 in Chinese men with CP/CPPS. A large cross-sectional and multicenter survey was conducted from July 2012 to January 2014. Men were recruited from urology clinics which were located at the five cities in China. All men participated in the survey by completing a verbal questionnaire (consisted of sociodemographics, past medical history, sexual history, and self-estimated scales). The results showed that 1,280 men completed the survey. Based on the CP/CPPS definition, a total of 801 men were diagnosed as having CP/CPPS. Men with CP/CPPS reported higher scores of NIH-CPSI and lower scores of IIEF-5 than men without CP/CPPS. NIH-CPSI scores were significantly negatively correlated with IIEF-5 scores. The total scores of NIH-CPSI were significantly more strongly correlated with question 5 than other questions of IIEF-5. The total scores of IIEF-5 were significantly more strongly correlated with pain symptoms scores of NIH-CPSI. Strongest correlation was found between QoL impact and question 5 of IIEF-5. The findings suggested that NIH-CPSI scores were significantly negatively correlated with IIEF-5 scores. Strongest correlation was found between QoL impact and question 5 of IIEF-5.

Background: The aim of this study was to investigate the relationship between serum CysC levels and high blood pressure (HBP) and to explore its diagnostic value for HBP in elder type 2 diabetic (T2D) population., Methods: A total of 369 elder T2D patients (age > 60) were included in this cross-sectional study. Their clinical and biochemical characteristics were detected. Patients were divided into two groups: with HBP and without. The risk factors of HBP were explored by binary logistic regression analysis., Results: The serum concentrations of CysC were 1.08 ± 0.42 and 0.90 ± 0.21 mg/L in patients with and without HBP, respectively. Binary logistic regression analysis showed that the significant risk factors were CysC (p = 0.000, OR = 16.977), systolic blood pressure (p = 0.000, OR = 1.087), and diabetes duration (p = 0.000, OR = 1.289). The prevalence of HBP increased with CysC (p < 0.05), and the prevalence of HBP in patients with CysC ≥ 1.2 mg/L was much higher than the other three quartile groups. The risk of HBP dramatically increased in patients with cystatin C ≥ 1.2 mg/L (OR = 1.601, 95% confidence interval 1.239 - 2.069, p = 0.000). After adjusting for gender, age, and diabetes duration, its OR still remained 1.633 (95% confidence interval 1.181 - 2.257, p = 0.003)., Conclusions: There was a strong and independent association between CysC and HBP in elder diabetic population, and cystatin C ≥ 1.2 mg/L indicated a great increased risk of HBP.
