Objective To summarize the operation period in the treatment of elderly patients with benign prostatic hyperplasia(BPH)clinical effect with inguinal hernia.Methods 60-96years old in elderly patients with BPH complicated with inguinal hernia in 53 cases,transurethral plasmakinetic resection of prostate (TUREP)or open operation for the treatment of benign prostatic hyperplasia,while using bard tension-free repair of inguinal hernia, disposable operation treatment of BPH complicated with inguinal hernia,the clinical effect and safety were observed. Results 53 cases were cured all operation,followed up for 6months to 2years,there were no recurrence of hernia operation,incision infection and other complications of operation.Micturition was apparent improvement.The average postoperative hospital stay was 7.6days,14 863 yuan for hospitalization.Conclusion It is safe and effective for sim-ultaneous TURP andinguinal hernia repair,which can avoid pain,and two times the risk of operation and anesthesia, especially has the positive significance in aged patients.

Objective To establish an external quality assessment ( EQA) system of genitourinary tract secretions routine testing in Guizhou Province and improve the overall testing level.Methods From 2009 to 2011, more than 50 clinical laboratories in different grade hospitals from Guizhou Province were enrolled as participating units every year.EQA was carried out twice a year.Each time, five slides of high quality Wright′s or Gram stain smear of the genitourinary tract secretions or photographs obtained from these smears were selected to send to the participating laboratories for testing, and the feedback results from each laboratory were analyzed.The qualification was judged by the coincidence rate equal to or more than 80%. The average coincidence rates of each time and each year were statistically analyzed by Chi-squared test. Results From 2009 to 2011, the number of EQA participating units increased from 55 to 96, with an average return rate of >80%.Coincidence rates <80%of the 6 EQA results in the 3 years were as follow:four times for coccobacteria (73.7%,77.8%,61.1%,77.1%), twice for bacillus (75.6%,79.3%) and coccobacillus (64.3%,52.1%), once for infusorian (79.7%), epithelial cells (76.1%), neutropenia (75.7%) and cleanliness (71.3%).There were six batches of 30 quality assessment controls (accounting for 20.0%) in the six EQAs had the coincidence rate of <80%.Eleven items of 30 quality assessment controls with 1 to 15 batches were unqualified ( average coincidence rate of<80%) respectively.The item with the highest total average coincidence rate was suspected gonococcus (94.2%), and two items with the lowest total average coincidence rates were coccus and coccobacillus ( 77.0%, 75.2%, respectively ) . Conclusions This EQA program carried out within a certain range of clinical laboratories achieved good results:participating units increased significantly;the total score of all the items showed an obviously upward trend;the quality awareness of clinical lab technicians has enhanced to a certain extent.In this study, EQA system of genitourinary tract secretion routine testing were preliminarily established in Guizhou province, which provided a reference model of internal quality control ( IQC ) and EQA for clinical laboratories and higher authorities, and will be bound to have a positive impact on improvement of the overall level of genitourinary tract secretion routine testing.

Objective:To explore the airway pathogen characteristics and examine the correlation between donor-derived pathogens and post-transplant outcomes in patients after lung transplantation (LT).Methods:Between January 1, 2015 and December 31, 2019, retrospective review was conducted for clinical and microbiological data of 88 LT recipients.Airway pathogen percentage of different microorganisms and evolution of drug-resistance were examined.Drug-resistant pathogen positive group (n=71) and negative group (n=17) were assigned according to whether or not drug-resistant pathogens were detected.Survival analysis was conducted by Log-rank with 3-year follow-ups.Between April 11, 2020 and September 5, 2020, prospective study was conducted in 14LT recipients.The potential pathogenic bacteria from donor lungs were detected by metagenomic next generation sequencing and the impact of those bacteria was examined on 1-year post-transplantation outcome in 2020.Microbial diversity and richness were shown with Shannon index.The outcome variables included heart rate, neutrophil count, lymphocyte count, immunoglobulin level and pulmonary spirometry.ANOVA and Pearson's correlation analysis were performed for elucidating the relationship between airway microbiota and post-LT outcomes.Results:From 2015 to 2019, 88 recipients were recruited and 992 strains of airway pathogens were isolated, including bacteria 796 strains and fungi 196 strains.Gram-negative bacteria (704 strains) accounted for 88.4% of all bacteria.The detection rates of Gram-positive bacteria, Klebsiella pneumonia (Kp), Acinetobacter baumannii (Ab), Stenotrophomonas maltophilia and Candida increased in 2019 than that in 2015 (8.2% vs. 5.3%, 13.6% vs. 13.2%, 33.2% vs. 17.5%, 6.5% vs. 5.3%, 26.6% vs. 20.2%). Drug resistance rate of Kp to imipenem was 68.18% in 2019 and drug resistance rate of Ab to imipenem 98.44%.The 3-year survival rate was 46.3% and 35.3% in drug-resistance positive and negative groups and the difference was insignificant ( P=0.410). Fourteen recipients were enrolled in 2020.Potential pathogenic bacteria could be detected in all donor samples.Five recipients carried the same bacteria and two died during 1-year follow-up.Nine recipients did not carry the donor-derived pathogens and two died during 1-year follow-up.The diversity of donor/recipient-derived airway microbiota (Shannon index) showed no correlation with the outcomes of 1-year follow-up by Pearson's correlation test. Conclusions:Gram-negative bacteria predominated in airway pathogens of recipients post-LT.The drug resistance rate to imipenem remained high.The donor/recipient-derived pathogen isolates showed no correlation with immediate outcomes post-LT.
