Characteristics of the urinary microbiota in UTUC patients / 中华泌尿外科杂志

Objective:To analyzed the urinary microbiota characteristics of upper tract urothelial carcinoma(UTUC) patients.Methods:Urine samples were collected from 23 patients with UTUC (UTUC group) and 22 patients with benign diseases (control group) admitted to Yijishan Hospital, the First Affiliated Hospital of Wannan Medical College from July 2021 to July 2022. The differences in age [(60.9±5.7) years vs. (61.4±8.8) years], sex (male/female: 15/8 vs. 9/13), and body mass index [(22.9±1.8) kg/m 2 vs. (23.4±1.7) kg/m 2] between the UTUC group and the control group were not statistically significant ( P>0.05). The V4 region of the 16S rRNA of urinary microorganisms was sequenced using the Illumina NovaSeq6000, and the results were processed using QLLME2. Differences in α-diversity between groups were analyzed by using the Shannon, Simpson, and Chao1 indices. Differences in β-diversity between groups were analyzed by using unweighted principal coordinates analysis (PCoA). Linear discriminant analysis Effect Size(LEfSe)was used to identify the bacterial taxa with different abundances between groups. Significant differences were defined as LDA>2. Results:The Chao1 index (703.12±265.54 vs. 506.20±214.02) and Shannon index (5.61±1.85 vs. 5.07±1.34) were significantly higher in the UTUC group compared to that in the control group ( P<0.05). The α-diversity of urinary microbes was elevated in the UTUC group compared to that in the control group but the difference in β-diversity was not statistically significant ( P=0.161). The enrichment of Bacteroidaceae, Ruminococcaceae, Acidaminococcaceae, Thermaceae, Erysipelatoclostridiaceae, and Coriobacteriaceae abundance was higher in the urine of UTUC patients(LDA > 2). Further subgrouping analyses of the UTUC patients showed that the differences in Chao1 index (706.44±271.84 vs. 784.09±272.72), Shannon index (6.04±1.30 vs. 5.91±1.67), and Simpson index (0.94±0.08 vs. 0.89±0.22) between the muscle-invasive group and the non-muscle-invasive group were not statistically significant ( P>0.05). The difference in α-diversity between muscle-invasive and non-muscle-invasive group was not statistically significant, but the difference in β-diversity was statistically significant ( P=0.047). The urinary microbial communities of Gammaproteobacteria, Cutibacterium, Rhodococcus and Nocardiaceae were enriched in muscle-invasive group and differed from that in non-muscle-invasive group(LDA>2). Conclusions:This study suggests that the urinary microbial community was more abundant in UTUC patients than in non-UTUC patients and that Bacteroidaceae, Ruminococcaceae, Acidaminococcaceae, Thermaceae, Erysipelatoclostridiaceae, and Coriobacteriaceae were more abundant in the urine of UTUC patients. The urinary microbial community was more abundant in the urine of non-muscle-invasive patients than in the muscle-invasive patients, and Gammaproteobacteria, Cutibacterium, Rhodococcus and Nocardiaceae were more abundant in the urine of non-muscle-invasive patients.

New coronavirus pneumonia: Question and confusion / 中国临床药理学与治疗学

The outbreak of new coronavirus pneumonia (COVID-19) in Wuhan and surrounding areas has brought huge challenges to China. As a new infectious disease, there are questions and confusion about its epidemiological characteristics and clinical treatment. Therefore, it is urgent to figure out how to achieve effective prevention, higher success rate of treatment and scientific management.

PROfound: A new hope for precise treatment of prostate cancer / 中国临床药理学与治疗学

Metastatic castrate-resistant prostate cancer (mCRPC) is the last stage of prostate cancer. Although new hormonal agents and taxane-based chemotherapies occurred for mCRPC treatment, the overall survival of mCRPC patients is limited. Olaparib is an inhibitor of poly ADP-ribose polymerase (PARP), which has a key role in DNA damage response. It has been approved for ovarian cancer and breast cancer treatment. PROfound, a phase III clinical trial of olaparib in mCRPC treatment, has been reported in 2019 ESMO and 2020 ASCO-GU. In this paper, we will bring the results and updates of PROfound.

Plasma cell-free DNA and its DNA integrity as biomarker to distinguish prostate cancer from benign prostatic hyperplasia in patients with increased serum prostate-specific antigen.

OBJECTIVES: To investigate whether plasma cell-free DNA (cfDNA) or its integrity could differentiate prostate cancer from benign prostate hyperplasia (BPH) in patients with serum prostate-specific antigen (PSA) ≥ 4 ng/ml. METHODS: Ninety-six patients with prostate cancer and 112 patients with BPH were enrolled. cfDNA levels in plasma before prostate biopsy were quantified by real-time PCR amplification of ALU gene (product size of 115 bp), and quantitative ratio of ALU (247 bp) to ALU (115 bp) reflected the integrity of cfDNA. RESULTS: In patients with serum PSA ≥ 4 ng/ml, there were significant differences in plasma cfDNA or its integrity between the patients with prostate cancer (19.74 ± 4.43, 0.34 ± 0.05) and patients with BPH (7.36 ± 1.58, 0.19 ± 0.03; P < 0.001, P < 0.001). Prostate cancer could be differentiated with a sensitivity of 73.2 % and a specificity of 72.7 % by cfDNA (AUC = 0.864). The integrity of cfDNA had a sensitivity of 81.7 % and a specificity of 78.8 % for the distinguishing prostate cancer from BPH (AUC = 0.910). CONCLUSIONS: cfDNA and its integrity could be applied to differentiate prostate cancer from BPH in patients with serum PSA ≥ 4 ng/ml.

Objective To summarize the operative experience and to study the value and efficacy of retroperitoneal laparoseopie adrenaleetomy.Methods Clinical data of 66 cases undergoing retroperitoneal laparoscopic adrenalectomy in Yijishan Hospital were retrospectively reviewed.There were 22 cases with adrenal adenoms located at left side and 44 cases at fight side.Tumor diameter was from 1.2 to 6.4 cm,with 3.3 cm as the average.There were 36 cases of nonfunctional adrenal adenoma,13 cases of primary hyperaldosteronism,10 cases of adrenal pheochromocytoma,6 cases of adrenal myelolipoma,and 1 case of adrenal cyst.Results 4 cases were converted to open surgery while the other 62 cases were completed successfully.The operation duration was from 35 to 190 min,with 90 min as the average.Intraoperative blood loss was from 20 to 800 ml,with 70 ml as the average.5 cases received blood transfusion because of massive hemorrhage.All cases were followed up for 3to 36 months.None of them had long-term complications or recurrence.Conclusion Retroperitoneal laparoscopic adrenalectomy has advantages of safety,less trauma,short hospitalization time,and quick recovery,making it the flint choice for patients with benign adrenal neoplasms.

The efficacy of naftopidil in treatment of female urethral syndrome / 医学研究生学报

Objective: To evaluate the efficacy and safety of Naftopidil on patients with female urethral syndrome (FUS). Methods: Self-controlled clinical trial was performed in patients with FUS. Thirty-eight patients were treated with naftopidil tablet 25mg/po/qn for 4 weeks after one-week washout period. The effects were evaluated mainly by female urethral syndrome score (FUSS) and quality of life (QOL). Results: FUSS began to decrease after 2 (week's) administration and decreased significantly after 4 weeks' treatment. It had statistically significant difference of FUSS and QOL after treatment compared with control (P
