Inflammatory myofibroblastic tumor (IMT)is a potentially or low-grade malignant mesenchymal neoplasm, which is rare in clinic. Renomedullary interstitial cell tumor(RICT) is a clinically rare benign renal tumor. The combination of these two diseases in one patient has not been reported. A 25-year-old female patient was admitted to the hospital due to left back pain for 12 days and hematuria for 1 week. MRI of kidneys showed a mass in the left renal pelvis, which was considered as renal pelvic carcinoma. Urine cytopathological examination was negative. Robot-assisted laparoscopic radical left nephroureterectomy was performed. There was no tumor recurrence or metastasis during the follow-up for more than 6 months after operation.

Objective:To compare the pathological results and complications of limited and extended pelvic lymph node dissection among high-risk prostate cancer patients, and to explore the risk factors that affect the rate of lymph node metastasis in high-risk prostate cancer patients.Methods:The data of 800 high-risk prostate cancer patients who underwent radical prostatectomy and pelvic lymph node dissection from January 2016 to December 2020 in three affiliated hospital of Sun Yat-sen University were analyzed retrospectively. According to the scope of pelvic lymph node dissection, they were divided into limited pelvic lymph node dissection (LPLND) group and extended pelvic lymph node dissection (EPLND) group. There were 172 patients underwent LPLND, and 628 patients underwent EPLND.The age of the patients in the LPLND group was 67 (62, 72) years old, diagnosed PSA 20.7 (10.9, 54.8) ng/ml. The biopsy Gleason score 6 in 22 cases, 7 in 59 cases, 8 in 56 cases and 9-10 in 35 cases.The clinical T stage: T 1 in 29 cases, T 2 in 102 cases, T 3 in 37 cases, T 4 in 4 cases; N 0 in 160 cases and N 1 in 12 cases. 50 patients received neoadjuvant hormonal therapy. The age of patients in the EPLND group was 67 (63, 72) years old, diagnosed PSA was 23.9 (14.0, 46.8) ng/ml. Biopsy Gleason Score 6 in 51 cases, 7 in 194 cases, 8 in 218 cases and 9-10 in 165 cases. Clinical T stage: T 1 in 114 cases, T 2 in 341 cases, T 3 in 144 cases, T 4 in 29 cases; N 0 in 526 cases and N 1 in 102 cases.158 patients received neoadjuvant hormonal therapy. There were no significant differences in the age, PSA, puncture Gleason score, clinical T stage, and whether or not to receive neoadjuvant hormonal therapy between the two groups of patients ( P>0.05). The difference in clinical N staging was statistically significant ( P=0.002). The number of postoperative lymph nodes, positive pelvic lymph nodes and postoperative complications and other related clinical and pathological data of the two groups were analyzed. Multivariate logistic regression was used to analyze the risk factors of patients with positive lymph nodes. Results:The median number of lymph nodes harvested [13(8, 19)vs. 6(4, 13), P<0.001] and the rate of positive lymph node cases[31.2%(196/628) vs. 10.5%(18/172), P<0.001] in the EPLND group was significantly higher than those in the LPLND group. Preoperative PSA, clinical N staging, Gleason score, and way of lymph node dissection were independent risk factors for postoperative positive pelvic lymph node in high-risk prostate cancer patients. Compared with the LPLND group, the ELPND group had a higher postoperative complication rate [19.9%(125/628) vs. 11.0%(11/172), P=0.007]. Conclusions:Compared with the LPLND, EPLND in high-risk prostate cancer patients can harvest more lymph nodes and increase the detection rate of positive lymph nodes. The complications of EPLND were higher than those of LPLND. Preoperative PSA, clinical N stage, Gleason score, and the way of lymph node dissection are independent risk factors for positive pelvic lymph node dissection.

Objective:To investigate the 2 years’ efficacy of intravesical instillation of domestic BCG versus epirubicin in the prevention of recurrence of intermediate-risk or high-risk non-muscular invasive bladder cancer and predictive factors of BCG instillation.Methods:From July 2015 to June 2020, 18-75 years old patients with moderate to high-risk non muscle invasive bladder cancer (NMIBC) confirmed by pathological examination were involved. The ECOG score was 0-2. Exclusion criteria included ①immune deficiency or impairment (such as AIDS), using immunosuppressive drugs or radiotherapy, suspected allergic to BCG or epirubicin or excipients of the two drugs, fever or acute infectious diseases including active tuberculosis or receiving anti tuberculosis treatment, with severe chronic cardiovascular and cerebrovascular diseases or chronic kidney disease; ②combined with other urogenital system tumors or other organ tumors; ③combined with muscle invasive bladder urothelial carcinoma (≥T 2); ④undergoing chemotherapy, radiotherapy or immunotherapy within 4 weeks (immediate instillation after surgery not included); ⑤ pregnant or lactating women; ⑥ comfirmed or suspected bladder perforation; ⑦gross hematuria; ⑧cystitis with severe bladder irritation that may affect the evaluation; ⑨participat in other clinical trials within 3 months; ⑩alcohol or drug addiction; ?any risk factors that may increasing the risk of patients. Epirubicin 50 mg was irrigated immediately after the operation(TURBT or laser resection). The patients were randomly divided into BCG15 group, BCG19 group and epirubicin group by the ratio of 2∶2∶1, and the patients were maintained intravescical instillation for 1 year. The recurrence and adverse events of the three groups were compared. Univariate and multivariate analysis was performed to predict the risk factors of BCG irrigated therapy failure. Result:By June 15, 2020, the median follow-up duration was 22.1 months(12.1, 32.3), and there was no statistical difference between the groups ( P=0.9024). There were 274 patients enrolled in BCG19 group, 277 patients enrolled in BCG15 group and 130 patients enrolled in the epirubicin group. The drop-off rate was 16.6%(113 cases)and made no difference between groups( P=0.6222). There were no significant difference in age, gender, BMI, or ECOG score( P>0.05). During the follow-up, 116 cases was detected recurrence or progression. The recurrence rate of the three groups was 14.2% and 14.8% in BCG19 group and BCG15 group, and 27.7% in the epirubicin group. There was no difference in recurrence rate between BCG19 and BCG15 group( P=0.9464). The recurrence rate of BCG19 group was lower than that of the epirubicin group ( P=0.0017). The recurrence rate of BCG15 group was lower than that of the epirubicin group ( P=0.0020). There was no difference in the cumulative recurrence free survival rate between BCG19 and BCG15 group (95% CI0.57-1.46, P=0.7173). The cumulative recurrence free survival rate of BCG 19 group was better than that of the epirubicin group( HR=0.439, 95% CI0.26-0.74, P=0.0006), and the cumulative recurrence free survival rate of BCG15 group was better than that of the epirubicin group ( HR=0.448, 95% CI0.29-0.80, P=0.0021). The total incidence of adverse events in 19 BCG19, BCG15 and epirubicin group were 74.5%, 72.6% and 69.8% respectively. There was no difference in the incidence of adverse events between BCG19 and BCG15 group( P=0.6153). The incidence of adverse events in epirubicin group was lower than that of BCG19( P=0.0051) and BCG15( P=0.0167) groups.There was no significant difference in the incidence of serious adverse events (SAE) among the three groups ( P=0.5064). Log rank test univariate analysis and Cox risk regression model multivariate analysis showed that the history of bladder cancer recurrence( HR=6.397, 95% CI1.95-20.94, P=0.0001)was independent risk factor for BCG irrigation failure. Conclusions:The 2 years’ efficacy of intravesical instillation of domestic BCG is better than than of epirubicin with good tolerance and safety. There is no difference between BCG19 and BCG15 group. BCG doesn’t increase SAE compared with epirubicin. Recurrence status was an independent prognostic factor regarding recurrence-free survival.

Objective To retrospectively analyze the application of lung ultrasound in neonatal de-partment of our hospital in the past three years,and summed up the clinical diagnosis and treatment changes brought by it. Methods The clinical data of infants accepted the bedside lung ultrasound examination from May to December 2016(early carry out stage),from January to December 2017(adaptation stage),from Jan-uary to August 2018(normal conduct stage) in our NICU of Jingzhou Central Hospital were collected. The clinical data of 878 infants with different stages of application were compared and analyzed. Results In 878 children,1 225 of lung ultrasound were performed,64. 1% of patients had pulmonary disease,and 35. 9% had no lung disease. There were 67 cases of neonatal respiratory distress syndrome,278 cases of wet lung,259 ca-ses of pneumonia,64 cases of meconium aspiration syndrome,72 cases of acute respiratory distress syn-drome,63 cases of atelectasis and 14 cases of pleural effusion. A total of 1 122 times of lung X-ray examina-tion were performed in 878 children. The number of X-ray examinations per capita decreased from 2. 48 times in 2016 to 1. 40 times in 2017 and 0. 84 times in 2018. A total of 32 times of pulmonary CT examination were performed. The number of lung CT inspection decreased from 0. 060 times in 2016 to 0. 038 times in 2017 and 0. 029 times in 2018. Lung ultrasound was convenient for dynamic observation,and could be used to de-termine the improvement,aggravation or new pulmonary lesions. Conclusion Lung ultrasound is accurate in the diagnosis of lung disease in NICU,especially for children with long hospital stay,repeated illness and dif-ficult to withdraw. It is easy to carry out in clinic,at the bedside,which can reduce the times of chest X-ray and CT per capita examination. Lung ultrasound is an effective and feasible method for NICU to diagnose lung diseases and it is worth promoting.

BACKGROUND@#Accurate evaluation of lymph node metastasis in bladder cancer (BCa) is important for disease staging, treatment selection, and prognosis prediction. In this study, we aimed to evaluate the diagnostic accuracy of computed tomography (CT) and magnetic resonance imaging (MRI) for metastatic lymph nodes in BCa and establish criteria of imaging diagnosis.@*METHODS@#We retrospectively assessed the imaging characteristics of 191 BCa patients who underwent radical cystectomy. The data regarding size, shape, density, and diffusion of the lymph nodes on CT and/or MRI were obtained and analyzed using Kruskal-Wallis test and χ test. The optimal cutoff value for the size of metastatic node was determined using the receiver operating characteristic (ROC) curve analysis.@*RESULTS@#A total of 184 out of 3317 resected lymph nodes were diagnosed as metastatic lymph nodes. Among 82 imaging-detectable lymph nodes, 51 were confirmed to be positive for metastasis. The detection rate of metastatic nodes increased along with more advanced tumor stage (P  6.8 mm may indicate metastatic lymph nodes in BCa.
