Objective To summary the experience of laparoscopic cystectomy ileal conduit (Bricker) and orthotopic ileal neo‐bladder (Hautmann) and compare the short‐term efficacy of the two types of urinary diversion for invasive bladder cancer . Methods Retorspective analysis of the patients in our hospital who accepted laparoscopic radical cystectomy from 2010 to 2014 was performed ,74 of them accepted ileal conduit ,and 30 of them accepted orthotopic ileal neobladder .The general clinical data ,postop‐erative recovery ,postoperative complications and Oncology feature were analyzed and compared between the two groups .Results There was no demonstrable difference was found in operation time ,blood loss ,intraoperative blood transfusion rate ,the number of removed lymph node ,average hospital stay ,specimens positive margin rate and postoperative pathology results between the two groups (P>0 .05) .But there were significant difference in postoperative intestinal function recovery time[(4 .2 ± 1 .4)d ,(5 .3 ± 2 .2)d] ,(P=0 .002) ,and the complication rates 31 .9% (23 cases)vs .53 .3% (16 case) ,P=0 .043 .After 6 months ,the daytime and nighttime urinary control were 76 .9% ,57 .7% ,after 12 months ,the daytime and nighttime urinary control increased to 90 .9% , 81 .8% .2 cases(7 .7% ) were diagnosed with recurrence or metastasis during follow‐up in Hautmann group ,while 9 cases(14 .1% ) were diagnosed with recurrence or metastasis in Bricker group .Conclusion Two kinds of surgical procedures both have the similar therapeutic effect ,but the postoperative quality of life is better for Hautmann orthotopic neobladder patients .

Objective:To investigate the clinical significances of evaluation indexes of right heart function injury in patients with BCR-ABL-negative myroproliferative neoplasms (MPN).Methods:The clinical data of 208 patients with BCR-ABL-negative MPN diagnosed in the Second People's Hospital of Lianyungang and Jiangsu Province Hospital from January 2015 to August 2021 were retrospectively analyzed, including 63 cases of primary myelopathic fibrosis (PMF), 39 cases of polycytosis vera (PV) and 106 cases of essential thrombocythemia (ET). The clinical characteristics of patients and the examination results of hematological related indicators were compared among the three groups. The examination results of indexes of right heart function injury were analyzed, including echocardiography, brain natriuretic peptide, soluble growth stimulation expression gene-2 (sST-2), lactate dehydrogenase (LDH), D-dimer, ferritin, β 2-microglobulin, peripheral blood WT1 gene, CD34 + cell count, etc. Results:Of the 208 patients, 109 were male and 99 were female; the median age was 62 years old (23 years old, 89 years old). The differences in levels of hemoglobin, platelet count, D-dimer, LDH and ferritin among PMF, PV and ET patients were statistically significant (all P < 0.05). Color echocardiography was performed in 87 patients, including 26 cases of PMF, 19 cases of PV and 42 cases of ET. Pulmonary artery pressure increased in 69 cases (79.3%), left atrial diameter increased in 76 cases (87.3%), and diameter increased during right ventricular diastolic period in 59 cases (67.8%). There were significant differences in pulmonary artery pressure, left atrial diameter and diameter during right ventricular diastolic period among PMF, PV and ET patients (all P < 0.05). Pearson correlation analysis showed that pulmonary artery pressure was positively correlated with ferritin, LDH, sST-2 and age ( r values were 0.796, 0.768, 0.915 and 0.734, all P<0.05), while it was negatively correlated with platelet count ( r = -2.330, P = 0.034). Conclusions:For BCR-ABL-negative MPN patients, the increase of pulmonary artery pressure, ferritin and LDH and the decreased platelet count and hemoglobin may increase the probability of right heart function impairment. For BCR-ABL-negative MPN patients with the higher levels of ferritin, LDH, sST-2, age, and the lower level of platelet count, the pulmonary artery pressure may be higher.

Objective:To investigate the therapeutic effect and safety of pomadomide combined with cyclophosphamide and dexamethasone (PCD) in the treatment of relapsed/refractory multiple myeloma (MM).Methods:The clinical data of 20 relapsed/refractory MM patients receiving PCD regimen in the Second People's Hospital of Lianyungang Affiliated to Bengbu Medical College from March 2021 to June 2022 were retrospectively analyzed; and 29 relapsed/refractory MM patients receiving other regimens including DECP (dexamethasone+etoposide+cyclophosphamide+cisplatin, 13 cases) and VCD (bortezomib+ cyclophosphamide+ dexamethasone, 16 cases) during the same period were treated as the control group. The efficacy and adverse effects of both groups were compared after 4 cycles of treatment.Results:After 4 cycles of treatment, the overall response rate (ORR) and the clinical benefit rate (CBR) of 20 cases in PCD group was 70.0% (14/20) and 85.0% (17/20), respectively; among 20 cases, there were 5 cases of complete response (CR), 4 cases of very good partial remission (VGPR), 5 cases of partial remission (PR), 3 cases of minimal remission (MR), 2 cases of stable disease (SD), 1 case of the progression of the disease (PD). ORR and CBR of 29 cases in the control group was 41.4% (12/29) and 65.5% (19/29), respectively; among 29 cases, there were 2 cases of CR, 3 cases of VGPR, 7 cases of PR, 7 cases of MR, 5 cases of SD, 5 cases of PD. There was a statistically significant difference in ORR of both group ( χ2 = 3.89, P = 0.048), while the difference in CBR of both group was not statistically significant ( χ2 = 2.30, P = 0.129). There were 2 patients with renal impairment achieving CR in PCD group and 1 patient with renal impairment achieving CR in the control group ( P = 0.152); 1 genetically high-risk patient achieved CR in PCD group and none of patients in the control group achieved CR, and the difference was statistically significant ( P>0.05). The common hematological adverse effects of two groups were anemia, neutropenia, thrombocytopenia; the common non-hematological adverse effects were malaise, infection and fatigue, and the differences were statistically significant (all P>0.05). The incidence of grade 3-4 infection was 25.0% (5/20) in PCD group and the disease was under the control after anti-infective therapy, and the incidence of grade 3-4 infection was 24.1% (7/29) in the control group; and the difference was not statistically significant ( P > 0.05). Conclusions:PCD regimen has good clinical efficacy and safety in treatment of relapsed/refractory MM.

【Objective】 To compare the efficacy and safety between partial tubeless and standard percutaneous nephrolithotomy in the treatment of upper urinary tract calculi. 【Methods】 The clinical data of 802 patients with upper urinary tract calculi treated at our hospital during Jun.2018 and Dec.2021 were retrospectively analyzed. The patients were divided into the partial tubeless group and standard group, and 60 cases in either group were selected by a simple random method. Clinical data, complications and stone-free rate were compared between the two groups. 【Results】 All 120 patients completed the operation successfully. The postoperative hospital stay, pain score and postoperative recovery of the partial tubeless group were significantly superior to those of the standard group (P<0.05). There were no significant differences in operation time, blood loss, complications and stone clearance rate between the two groups (P>0.05). 【Conclusion】 In the treatment of upper urinary tract calculi, partial tubeless percutaneous nephrolithotomy can achieve satisfactory surgical results, and has obvious advantages in postoperative recovery and patients’ experience. It is worthy of clinical application.
