Background: Varicocele is the most prevalent correctable cause of male infertility. Currently, surgical treatment is the primary method to enhance fertility.For many young varicocele patients who have postponed surgery due to time constraints, daytime surgery is especially crucial. Thus, this study aims to investigate the clinical and nursing application value of the Plan-Do-Check-Act (PDCA) cycle in daytime varicocelectomy. Methods: Retrospective collection of clinical data was conducted on 130 patients undergoing laparoscopic varicocelectomy in the Third Affiliated Hospital of Southern Medical University, Guangzhou,China.Among them, 65 patients who underwent daytime surgery were assigned to the observation group, while 65 patients who underwent routine hospital surgeries were assigned to the control group.The former also implemented PDCA cycle management.A comparison was made between the two groups regarding hospitalization time, hospitalization costs, and patient satisfaction. Results: The observation group exhibited a shorter hospitalization time and lower hospitalization costs compared to the control group, with higher patient satisfaction and pre-discharge visual analog scale (VAS) scores noted (P < 0.05).No significant difference was observed in the incidence of postoperative complications between the two groups during hospitalization (P > 0.05). The implementation of the PDCA cycle in the observation group has demonstrated its effectiveness, ensuring the smooth conduct of the daytime varicocelectomy. Conclusion: In conclusion,daytime varicocelectomy can reduce hospitalization time,lower hospitalization costs, improve patient satisfaction. The PDCA Cycle enhances the rationality and efficacy of the daytime varicocelectomy procedure and is highly recommended. Furthermore, it offers valuable reference for the application of the PDCA Cycle in various other diseases and nursing management approaches.

Background: Expanded carrier screening (ECS) has emerged as an effective approach to identify at‐risk couples (ARCs)—before they initiate attempts at reproduction—who possess a high probability of having a child affected by severe recessive diseases. The objective of this study was to evaluate the clinical utility of ECS in Chinese patients seeking the help of assisted reproductive technology (ART). Methods: An ECS test, which covers 201 genes implicated in 135 recessive (autosomal or X‐linked) diseases, was routinely offered to all ART patients in a single genetics and in vitro fertilization clinic. Additional options for preimplantation or prenatal genetic diagnosis were discussed and offered to all ARCs. All ECS results were aggregated and the clinical decisions of the ARCs were surveyed. Results: A total of 2,923 ART patients, representing 1,462 couples, were screened. Overall, 46.73% of the individuals were found to be the carriers for at least 1 of the 135 diseases. Of the tested couples, 2.26% (n = 33) were identified as ARCs. As of the completion of this study, 21 (63.6%) ARCs have decided to avert an affected pregnancy with the help of preimplantation genetic testing for monogenetic conditions. The cumulative carrier rate of the 187 autosomal recessive genes in the ECS panel for the 2,836 Han Chinese individuals without a family history was estimated to be 45.91%. The estimated at‐risk couple rate indicates that the screening for only the top 31 genes with gene carrier rates >0.5% would identify more than 94% of the ARCs identified by screening all 187 genes. Conclusion: Our study demonstrates that ESC yields a significant clinical value for ART patients in China. In addition, by estimating the yields of the ECS panel, we identify genes that are appropriate for screening the Han population. [ABSTRACT FROM AUTHOR]

China has witnessed unprecedented rapid and massive urbanization in recent years, and the urbanization has influenced almost all corners of the country, which is a natural process and necessary result of the social and economic development. Development and expansion of cities has been the keynote of the contemporary era. Meanwhile, existence and future development of traditional urban areas that have gone through the long-term natural development have been faced with serious crisis. This paper focused on the relative constancy and changeability of major elements in the natural evolution of traditional cities and towns, so as to explore an organic development mechanism, and make a daring attempt in update planning of old downtown areas of Taiping Town in Shuangliu County. On this basis, the paper aims at exploring a new development concept for common cities and towns that balances inheritance and innovation. [ABSTRACT FROM AUTHOR]

Objective: To report how the Chinese mainland battled its first omicron wave, which happened in Tianjin, a metropolis with 14 million residents. We also sought to better understand how clinical features affected the timing of viral clearance., Design: A retrospective study of the omicron wave in Tianjin between 8 January 2022 and 3 March 2022., Setting: Except for the first cases on 8 January, all the omicron cases were identified through PCR mass testing in the residential communities. Residential quarantine and serial PCR mass testing were dynamically adjusted according to the trends of new cases., Participants: All the 417 consecutive PCR-positive cases identified through mass screening of the entire city's 14 million residents. 45.3% of the cases were male, and the median age was 37 (range 0.3-90). 389 (93%) cases had complete data for analysing the correlation between clinical features and the timing of viral clearance., Main Outcome and Measure: Time to viral clearance., Results: Tianjin initiated the 'dynamic zero-COVID' policy very early, that is, when daily new case number was ≈0.4 cases per 1 000 000 residents. Daily new cases dropped to <5 after 3 February, and the number of affected residential subdivisions dropped to ≤2 after 13 February. 64% (267/417) of the cases had no or mild symptoms. The median interval from hospital admission to viral clearance was 10 days (range 3-28). An exploratory analysis identified a feature cluster associated with earlier viral clearance, with HRs of 3.56 (95% CI 1.66 to 7.63) and 3.15 (95% CI 1.68 to 5.91) in the training and validation sets, respectively., Conclusions: The 'dynamic zero-COVID' policy can suppress an omicron wave within a month. It might be possible to predict in advance which cases will require shorter periods of isolation based on their clinical features., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objectives: To compare the DNA-based sputum evaluation with histopathology for the diagnosis of tracheo-bronchial tuberculosis (TBTB)., Study Design: Case series.   Place and Duration of Study: Tianjin Haihe Hospital, Tianjin Institute of Respiratory Diseases, Tianjin, China, from January to June 2017., Methodology: TBTB patients, who underwent bronchoscopy during the study period, were included. Their bronchoscopy presentations, histopathology, and induced sputum deoxyribonucleic acid (DNA) and culture results were analysed. Results were expressed as frequency percentage., Results: There were 110 subjects. Most patients were young females with coughing. The main TBTB subtype was fibrostenotic, while the most common findings were single level lesions and lobar bronchi. The diagnostic rates were 40.43%, 67.86%, and 68.54% for DNA-based analysis of induced sputum, histopathology, and induced sputum culture, respectively. Only in the edematous-hyperemic subtype was the positivity rate of DNA-based analysis of induced sputum higher than in histopathology. In the fibrostenotic subtype, the histopathologic results were superior for diagnosis., Conclusion: A combination of induced sputum and biopsy using DNA-based methods is a superior and exact method to diagnose TBTB. DNA-based analysis of induced sputum for mycobacterium tuberculosis can be used for preliminary impressions.

Identify the treatment effects and risk factors for mortality in patients with pulmonary tuberculosis receiving antituberculosis treatment under the Directly Observed Treatment Short-Course (DOTS) program to reduce the mortality rate of tuberculosis. A retrospective cohort analysis was conducted on the outcomes of antituberculosis treatment of 7,032 patients with tuberculosis in the DOTS program, in the Tuberculosis Management Information System from 2014 to 2017 in Tianjin, China. The Kaplan-Meier method and multifactor Cox proportional risk regression model were used to analyze the risk factors for mortality during antituberculosis treatment under DOTS. The success rate of antituberculosis treatment was 90.24% and the mortality rate was 4.56% among 7,032 cases of tuberculosis in Tianjin. Cox regression analysis showed that advanced age, male sex, human immunodeficiency virus (HIV) positivity, first sputum positivity, retreated tuberculosis, and a delayed visit (≥14 days) were risk factors for mortality in patients with pulmonary tuberculosis receiving antituberculosis treatment under DOTS. The treatment effects in patients with pulmonary tuberculosis during antituberculosis treatment under DOTS were positive in Tianjin. Advanced age, male sex, HIV positivity, first sputum positivity, retreated tuberculosis, and a delayed visit (≥14 days) increased the risk for mortality during antituberculosis treatment., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2020 Yi Xie et al.)

Cystic fibrosis (CF) is one of the most common autosomal recessive disorders among Caucasians of Northern European descent but is uncommon in the Chinese population. Objectives . To elucidate the mutation in the novel compound heterozygous CFTR causing CF in Chinese family. Materials and Methods . Clinical samples were obtained from a Chinese family, the brother and sister with recurrent airway infections, hypoxemia and obstructive ventilatory impairment, sinusitis, clubbed fingers, salty sweat, and nasal polyposis. We performed whole-exome sequencing on the family and validated all potential variants by Sanger sequencing. Results . Next-generation sequencing showed a novel compound heterozygous CFTR mutation (c.400 A > G p.Arg134Gly and c.3484 C > T p.Arg1162 ∗ ) which resulted in CF in the family. Conclusions . As this mutation is consistent with the observed clinical manifestations of CF and no other mutations were detected after scanning the gene sequence, we suggest that their CF phenotypes are caused by the compound heterozygous mutation, c.400 A > G p.Arg134Gly and c.3484 C > T p.Arg1162 ∗ . As c.400 A > G is not currently listed in the Cystic Fibrosis Mutation Database, this information, regarding the CF-causing mutations in two Chinese patients, is of interest., Competing Interests: The authors declare that there are no conflicts of interest regarding the publication of this article., (Copyright © 2020 Hongxia Shao et al.)
