Objective To understand the infection of ureaplasma urealyticum in genitourinary of secondary infertility of male and ex-plore the relationship between the genotype of individual ureaplasma species and genitourinary infection of them . Methods Based on the multiple-banded antigen genes (MBA) of ureaplasma urealyticum, 10 pairs of oligonueleotide primers targeting the 5'ends of the MBA genes were designed to identify the MBA genes of U. parvum and U. ureaplasma by PCR-based genotyping system. The 10 pairs of oligonucleotide primers could distinguish the two biovars and 14 serovars of U. ureaplasma. Results A total of 278 (48.6%) positive ureaplasma culture were obtained from 572 patients attending our clinic of reproductive medical eenter. These methods were used to identify and genotype U. ureaplasma in 311 (54.4%) of 572 patients with genitourinary infection among them U. parvum (biovar 1) was detected in 37.1% and U. ureaplasma (biovar 2) in 17.8%. serovar 1 was in 12.4%, serovars3/14 in 17.1% serovar 6 in 7.5%; subtype 1 of biovar 2 was in 5.6%, subtype 2 in 8.9% and subtype 3 in 2.8%, respectively. Conclusion The PCR-based genotyping system will facilitate future stud-ies of relationship between individual Ureaplasma species or subtypes in genitourinary of secondary infertility of male. The methods described here are relatively rapid, practicable, and specific for the detection species identification and subtyping of Ureaplasma species.

Objective To investigate radioactivity levels in the main agriculture products around a uranium mine in Northern Guangxi.Methods The agriculture products and soil samples were collected and analyzed by using HPGe gamma ray spectrometer.Results The specific activity of 226Ra in radish (including leaf),radish leaves and radish,collected in one place,were 45.0,66.7 and 32.3 Bq/kg,respectively.Those of 226Ra and 23SU in the radish soil collected in the same place were 19 672 and 85 917 Bq/kg,respectively.The transfer coefficients of soil-to-radish and soil-to-leaves were 1.61 × 10-3 and 3.40 × 10-3,consistent with those reported in relevant literature.Radioactivity levels in agricultural products in another survey was in consistence with those in the national survey for food products.Radioactivity levels in soil elsewhere near the radish site was consistent with the results of the national soil radioactivive background survey.Conclusions The soil in this place has been contaminated by the nearby uranium mine.It is important to investigate this place further and take the necessary measures.

Objective:In order to develop a comprehensive hospital debt risk model,it is imperative to conduct an analysis of the present debt risk landscape within public hospitals,so as to furnish hospitals with recommendations to avert potential debt risks.Methods:A debt risk model was constructed based on 7 common factors through the extraction and standardization of data from 25 indicators,using 600 public hospitals in a specific province as samples,followed by factor analysis.Results:The model's calculation of the comprehensive score of public hospitals aligns with professional explanations and provides a more accurate representation of the factors influencing the debt risk level of public hospitals,such as financial investment level,hospital type,hierarchy,and others.Conclusion:In conclusion,the model is efficient.It is imperative to adopt a comprehensive perspective on the matter of hospital debt and efficiently address the associated financial risks faced by public hospitals by fostering collaboration among multiple stakeholders and upholding fundamental principles.

Objective:To conduct a scoping review on gamified exercise interventions for elderly patients with cognitive impairment to provide insights for the application of gamification design in exercise programs for this population.Methods:Guided by the scoping review framework proposed by Arksey and O'Malley, a systematic search was conducted in databases including China National Knowledge Infrastructure, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, CINAHL, Web of Science, Scopus, ProQuest, and Wiley Online Library. The search covered the period from the establishment of the databases to June 12, 2024. An integrative analysis was performed on the included literature.Results:A total of 12 studies were included. The most commonly used gamification elements were achievement- and progress-oriented features, while the most frequently applied behavior change theories were behavior change techniques and social cognitive theory.Conclusions:Gamification-based exercise interventions can improve adherence to exercise programs in elderly patients with cognitive impairment, promote physical activity, and enhance cognitive function. Future research should focus on combining various theories with different gamification elements to encourage proactive exercise behavior in elderly individuals with cognitive impairment.

Objective To compare the MRI features of ovarian thecoma-fibroma and adult-type ovarian granulosa cell tumor (OGCT),and to investigate the differential value of MRI.Methods 13 patients (8 cases of ovarian thecoma-fibroma,5 cases of adult-type OGCT)confirmed by pathology were collected,in which MRI findings were analyzed retrospectively.Results 13 lesions were all unilateral.The shape of more lesions appeared round or oval,and huge lesions were lobulated.Most tumors were dominant solid and well-defined borders.The length-diameter of ovarian thecoma-fibromas ranged from 23 to 268 mm,with the mean diameter of (124±84)mm;on T1WI the solid part of tumors showed equal signal in 5 cases,slight lower signal in 3 cases,on T2WI all tumors were heterogeneous signal,6 lesions appeared equal signal with obscure nebulous high signal;all of 8 lesions were enhanced slightly;4 cases were accompanied with pelvic effusion and other type tumors of the ovarian.The length-diameter of adult-type OGCT tumors ranged from 27 to 110 mm, with the mean diameter of (84±33)mm;the solid part of lesions showed slight lower signal on T1WI and high signal on T2WI,the honeycomb and fissure cystic areas were found in all tumors,4 cases were accompanied with hemorrhage;all tumors were enhanced from moderately to highly,and delay contrast enhancement;the cases were accompanied with endometrial hyperplasia in 3 cases,endometrial carcinoma in 1 case.The non-enhanced cystic areas of two groups of tumors showed lower signal on T1WI and high signal on T2WI. Conclusion There are different characteristics between ovarian thecoma-fibroma and adult-type OGCT on MRI findings,which are helpful to the differential diagnosis.

Objective:To investigate the prevalence of anxiety and depression in patients undergoing thoracic tumor radiotherapy, preliminarily evaluate the nutritional risk of patients, and analyze the possible influential factors of anxiety and depression and their correlation with nutritional risk, providing a theoretical basis for further formulating a personalized psychological nursing plan for patients undergoing thoracic tumor radiotherapy.Methods:A total of 121 patients who underwent thoracic tumor radiotherapy between April 2019 and March 2020 in Cancer Hospital of The University of Chinese Academy of Sciences were selected for this study. We evaluated patients' psychological statuses using the Hospital Anxiety and Depression Scale and patients' nutritional risk using the Nutrition Risk Screening. We performed univariate analysis, unconditional logistic regression analysis, and contingency analysis to analyze the factors that affected the psychological status of patients undergoing thoracic tumor radiotherapy and correlate patients' psychological status with nutritional risk.Results:Among 121 patients, 99 (81.8%) patients undergoing thoracic tumor radiotherapy would develop or had developed anxiety, and 42 (34.7%) patients were at the boundary of depression or had depression. Correlation analysis revealed that nutritional risk was correlated with the prevalence of anxiety and depression. Logistic regression analysis showed that surgery, first radiotherapy, and nutritional risk were the factors that affected the prevalence of anxiety. Marital status, location of tumors, surgery, first radiotherapy, and nutritional risk affected the prevalence of depression.Conclusion:Patients undergoing thoracic tumor radiotherapy have serious psychological problems. Nutritional risk is positively correlated with the prevalence of anxiety and depression. Surgery and first radiotherapy are the factors that affect the prevalence of anxiety and depression.
