RESUMO
Since the COVID-19 outbreak began, a large number of studies have been conducted in a short period. However, it is unclear whether countries involved in this crisis have made adequate efforts and allocated resources to cutting-edge SARS-CoV-2 research. We analyzed the dynamics of and professional fields represented by papers about this novel coronavirus published before June 15, 2020. High-infection countries produced more scientific output than low-infection countries, and high-income and upper-middle-income countries were the main contributors. However, the research areas overlapped substantially, indicating a waste of resources. Our findings also suggest that international cooperation among countries is still relatively lacking, and all countries should make better use of their strengths to face the epidemic jointly.

RESUMO
Objective To study the factors that might influence the PSA-value. Methods Serum samples were collected from 165 cases of benign prostate hyperplasia (BPH),43 cases of prostate cancer (PCa) and 41 cases of chronic prostatitis (CP),both before and after digital rectal examination (DRE),cystoscope examination,indwelling catheterization and finasteride intake. Results In the BPH group,T-PSA elevated from (2.28?2.07)ng/ml to (4.77?5.23)ng/ml, P
RESUMO
ObjectiveTo study the diagnosis and treatment of peripelvic cysts.MethodsA view of the diagnosis and treatment of 14 cases and an evaluation of the different means of diagnosis and treatment were carried out.Results12 cases were followed up for 6～48 months post-operatively.11 cases were well recovered,with no reoccurrence or complication,and in 2 the high blood pressure dropped to normal whereas repeated urinary infection has been noted postoperatively in 1.ConclusionsB supersonic exam,KUB+IVU,CT exam are the most effective means to the diagnosis of this disease,CT exam being the first choice.Open renal cystectomy is indicated.
