Objective To assess the efficacy and safety of combining rociverine tablets with Suoquan cap-sules in the treatment of female patients with overactive bladder(OAB).Methods 152 female patients with OAB were randomly divided into three groups.Patients in rociverine group were administered rociverine tablets 10mg three times a day for 4 weeks.Patients in Suoquan capsule group were administered Suoquan capsules 1.8g three times a day for 4 weeks.Patients in combination group were administered rociverine tablets 10mg and Suoquan capsule 1.8g three times a day for 4 weeks.Each group of patients had to complete 3d voiding diary before and after treatment to record daily frequency of micturition,urgency,urgency incontinence,nocturia and avoiding volumes,OABSS score and drug side effects were also observed.All the data were analyzed to assess the efficacy and safety of treatment.Results There were significant differences in daily frequency of micturition,urgency,urgency incontinence,nocturia,avoiding volumes and OABSS score of patients in each group before and after treatment(all P <0.01 ).Moreover,compared with combination group,rociverine and Suoquan capsule group all had significant differences(F =41.765,53.834, 25.304,37.867,214.791,73.486,all P <0.01 ).There was no significant differences between rociverine and Suoquan capsule group(all P >0.05).The incidence rates of adverse events of rociverine and combination group were 7.8% and 22.6%,respectively,there was significant difference between the two groups(χ2 =4.372,P =0.032). Conclusion Combining rociverine tablets with Suoquan capsules in the treatment of female patients with OAB was effective and safe.

Objective To compare the safety and efficacy of 1 470 nm diode laser vaporization of the prostate with transurethral resection of the prostate (TURP) in patients with benign prostatic hyperplasia (BPH).Methods From July 2014 to July 2015,82 patients diagnosed as BPH were randomly divided into two groups.Forty cases of them underwent 1 470 nm diode laser vaporization and 42 cases for TURP.The operation time,hemoglobin decrease,serum sodium decrease,bladder irrigation time,duration of bladder catheterization and postoperative complications were recorded.The international prostate symptom score (IPSS),maximum flow rate (Qmax) and post-voiding residual volume (PVR) before and after operation were compared.Results No differences were found between the two groups in basic preoperative characteristics,such as:age,prostate volume,IPSS,PVR and Qmax(P＞0.05).The mean operative time in the diode laser group was (64.8±14.6) min,slightly longer than tin he TURP group ((59.3 ± 14.5) min,P＞0.05).The hemoglobin decrease,the serum sodium decrease,the time of bladder irrigating and the time of catheterization of 1470 nm diode laser group were all less than that in TURP group,the differences were significant between the two groups((2.06±1.43) g/L vs.(6.07±1.68) g/L,(1.16±0.67) mmol/L vs.(4.09±3.78) mmol/L,(5.08±2.80) h vs.(25.8±12.7) h,(3.38±1.17) d vs.(4.88± 1.42) d,respectively;t =-11.615,-4.845,-10.337,-5.232;P＜0.001).The complications in 1470nm diode laser group were less than that in TURP group,but the differences were not significant between the two groups(P＞0.05).All patients were followed up for 3-12 months,the IPSS,PVR and Qmax of 3 months after surgery in 1 470 nm diode laser group and TURP group were all improved significantly compared with that of preoperative in both groups,but no statistical differences could be found between the two groups(IPSS:F inner grouP=527.65,P＜0.001;F between groups=0.099,P=0.753;F across groups=0.040,P=0.843,PVR:F inner grouP =509.57,P＜ 0.001;F between groups =2.817,P =0.097;F across groups =1.02,P=0.315;Qmax:inner grouP=60.06,P＜0.001;F between groups =0.30,P=0.585;F across groups =0.394,P=0.532).Conclusion 1 470 nm diode laser vaporization of the prostate can significantly improve the patient's lower urinary tract obstruction symptoms,which show similar short-term effects with TURP.It also has advantages of less bleeding,shorter catheter indwelling time and rapid postoperative recovery compared with TURP,suggesting that it is a safe and effective operation for BPH treatment.

Objective To assess the risk factors of the in-hospital mortality of acute type A aortic dissection after operation. Method From January 2003 to June 2008,185 patients, 144 males and 41 females, with acute type A aortic dissection operated on were enrolled. The average age of patients was (49.46 ± 11.04 ) years old.The patients' demographics, history, clinical features, and some laboratory examinations were reviewed. Univariate and multivariate analysis followed by logistic regression analysis were carried out to identify the predictors of inhospital mortality. Results The in-hospital mortality rate was 9.1%. The results of univariate and multivariate analyses as follows: pre-operation positive neurological symptom (Univariate OR = 5.084,95%CI:1.792 -14.426, P = 0.002; Multivariate OR = 5.538,95%CI: 1.834 - 16.721, P = 0.002, respectively), hypotension (Univariate OR = 6.986,95%CI:1.510- 32.323,P =0.013; multivariate OR = 1.998,95%CI:0.315-12.679,P = 0.463, respectively) and renal failure (Univariate OR = 3.594,95%CI:1.237 - 10.438,P =0.019; Multivariate OR = 3.254,95%CI:1.034- 10.242, P= 0.044, respectively). Conclusions There are two predictors, pre-operation positive neurological symptom and renal failure, of pre-hospital mortality found in current analyses. Our results may improve the regimen made by cardiac surgeons and emergency doctors so as to help patients and their relatives to make correct decision.

Objective To compare the effect of breast conserving surgery and modified radical mastectomy on the clinical efficacy of patients with early breast cancer.Methods CNKI,Chinese Journal Full-text Database (CJFD),China Biology Medicine Disc (CBMdisc),China Dissertation Database (Chinese Dissertation Database,CDDB) google academic and other databases were comprehensive searched.And then the search time was limited to between January 1,2015 and September 1,2017.Key words can be locked for breast conserving surgery,improved surgery for breast surgery,case-control studies,etc.,and then meet the conditions of the literature into the study,for a retrospective analysis.The authors reviewed the literature independently,extracted data and evaluated the risk of bias,and used Review Manager 5.3 software for systematic analysis.Results A total of 1 093 patients with early breast cancer were enrolled in the study.The Meta-analysis showed:there was a significant difference in operation time between the two groups(MD =-30.71,95％ CI:-31.96--29.46,P ＜ 0.01);there was a significant difference in intraoperative blood loss between the two groups(MD =-53.30,95％ CI:-55.38--51.22,P ＜ 0.01);there was a significant difference in postoperative hospital stay (MD =-5.66,95％CI:-7.17--5.17,P ＜0.01) and the incidence of complications (OR =0.30,95％ CI:0.19-0.47,P ＜ 0.01)compared with modified radical mastectomy in early breast cancer patients.There was no significant difference between the two groups in the postoperative recurrence and metastasis (OR =0.78,95％ CI:0.54-1.13,P =0.19).Conclusions In the choice of surgical methods,breast-conserving therapy is better than modified radical surgery,and postoperative recurrence and metastasis rate has no significant difference.

Objective To study the correlation between ABCC3 gene and bladder cancer cell proliferation,drug resistance and aerobic glycolysis.Methods Lipofectamine 2000 reagent was used for small interfering RNA (siRNA) transfection.Human ABCC3 siRNA and negative control siRNA were transfected into UMUC-3 and 5637 cells separately,and bladder cancer cells were divided into siABCC3-1 group,siABCC3-2 group and control group.Western blot assay was used to evaluate the ABCC3 expression levels.Quantitative real-time polymerase chain reaction (PCR) was performed to determine the ABCC3 mRNA expression levels.The effect of ABCC3 on bladder cancer cell growth was determined by colony formation assay.We also analyzed the sensitivity of cance cells to cisplatin by MTT assay.The effect of ABCC3 on aerobic glycolysis were detected by measuring LDHA protein levels,lactate production and glucose consumption.The measurement data were expressed as ((x) ± s) tandard deviation.The difference between the groups was analyzed by single factor analysis of variance and LSD.Results Both protein and mRNA levels of ABCC3 were significantly decreased after si-ABCC3 transfection.Bladder cancer cells treated with si-ABCC3 exhibited significantly lower colony numbers than that of the control group.5637 cells treated with siABCC3-1 and siABCC3-2 were 4.02 μg/ml and 3.91 μg/ml,respectively.The IC50 values of cisplatin after UMUC-3 cells siABCC3-1 and siABCC3-2 were 2.54 μg/ml and 2.49 μg/ml,respectively.The expression of lactate dehydrogenase A protein in bladder cancer cells was down-regulated and the expression of ABCC3 was positively correlated with the expression of LDHA (P =0.0362).siABCC3-1 and siABCC3-2 were transfected into 5637 cells,respectively.The glucose consumption decreased by 43.2％ and 43.7％ respectively.The lactic acid production was reduced by 31.3％ and 29.7％,respectively.After transfection of UMUC-3 cells with siABCC3-1 and siABCC3-2,glucose consumption decreased by 33.4％ and 37.5％,respectively,and lactic acid production decreased by 24.7％ and 25.2％,respectively,compared with the control group,the difference was statistically significant (P ＜ 0.001).Conclusions ABCC3 is an important oncoprotein involved in cell proliferation,glycolysis and drug resistance.It could be a promising predictive biomarker and potential therapeutic target for bladder cancer.

OBJECTIVETo study the safety and effectiveness of laparoscopic radiofrequency ablation for centrally located renal tumors.

METHODSFrom January 2009 to April 2013, thirteen patients who diagnosed as centrally located renal tumors were treated with laparoscopic radiofrequency ablation in the Department of Urology of Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School. All of the cases were T1aN0M0 stage, 9 patients were male, 4 were female, the mean age was 56 years (range, 38-73 years). All tumors were unilateral, eight lesions were in the left kidney and five in the right kidney. Intraoperative real-time ultrasound and temperature probes were used to guide the range of radiofrequency ablation. Ice saline was injected through ureteral catheter for cooling the collecting system. The postoperative serum creatinine and glomerular filtration rate (GFR) data were collected,all patients were followed up with enhanced CT or MRI.The pre- and post-operative date were compared by paired t test.

RESULTSAll patients underwent laparoscopic radiofrequency ablation successfully. The mean operation time was (113±13) minutes and the mean blood loss was (99±23) ml. The mean pre- and post-operative serum creatinine was (71±11) µmol/L and (74±11) µmol/L, the mean pre- and post-operative GFR was (49±8) ml/min and (45±7) ml/min. There was no significant statistic difference between pre-operation and post-operation (t=-1.371 and 1.986, P>0.05). The mean follow-up was 37 months, range 12-63 months. No evidence of local recurrence or distant metastasis was found.

CONCLUSIONSLaparoscopic radiofrequency ablation for T1aN0M0 centrally located renal tumors could be performed safely with good outcomes. Intraoperative real-time ultrasound and temperature probes are helpful to control the range of radiofrequency ablation. Physical cooling of renal collecting system could reduce the occurrence of postoperative hydronephrosis and leakage of urine.

Objective:To analyze the clinical features of patients with pyogenic liver abscess (PLA) and the application of mNGS in PLA, thus to provide reference for clinical diagnosis and treatment.Methods:The demographic and clinical data of 549 patients with liver abscess admitted to Zhongshan Hospital Affiliated to Fudan University from December 2015 to June 2020 were analyzed retrospectively. According to the detection of Klebsiella pneumoniae in 246 patients with positive etiological test results, the patients were divided into two groups: KPLA group and nKPLA group, and clinical characteristics of the two groups were compared. At the same time, the application value of mNGS in PLA was analyzed.Results:Among the 549 patients, the main clinical symptom of PLA was fever ( n= 503, 91.6%) and other clinical symptoms included chills and abdominal pain. Most patients had a single abscess ( n= 464, 84.5%) located in the right lobe ( n = 368, 67.0%), with a size between 5 and 10 cm ( n= 341, 62.1%). A total of 246 patients had positive etiological test results, including 202 KPLA patients which was the main pathogen of liver abscess. The prevalence of diabetes and fatty liver was higher in KPLA patients ( P < 0.05), but there were more culture of liver positive factors in nKPLA patients ( P < 0.001). Among the 109 patients with traditional microbiological results, 92 patients were suspected to KPLA (Klebsiella pneumoniae), of which 14 patients (15.2%) were multidrug resistant (MDR) infection; 17 patients were suspected to nKPLA, of which 10 patients (58.8%) were MDR infection; the incidence of MDR infection in patients with nKPLA was significantly higher than that in patients with KPLA ( P < 0.05). The positive rate of mNGS in plasma was 85.2%, the positive rate of traditional microbial culture in plasma was 14.8%, the positive rate of mNGS in pus was 96.2% and traditional microbial culture in pus was 65.4%. The positive rate of traditional culture was significantly lower than that of mNGS ( P < 0.05). Conclusions:PLA is usually manifested as fever, single and at the right lobe of the liver. Klebsiella pneumoniae is the most common pathogenic bacteria of PLA, which is more common in patients with diabetes and fatty liver, while non-Klebsiella pneumoniae is relatively more common in patients with culture of liver positive factors. The positive detection rate of mNGS is high, which has a unique advantage in pathogen detection.

Objective: To analyze the computed tomography(CT) features and clinical outcomes of renal epithelioid angiomyolipoma(EAML). Methods: From January 2004 to June 2015, 17 patients with EAML in the Second People′s Hospital of Lianyungang and Nanjing Drum Tower Hospital were included in the study.All patients underwent CT examination.The patients' general data, imaging characteristics and pathologic features were determined by chart review. Results: Nine patients underwent radical nephrectomy, and 8 patients underwent partial nephrectomy.The mean maximal tumor diameter was 6.1 cm (ranged 1.2-12.5 cm). The fat component of one lesion was detected by CT.On unenhanced CT, the intratumoral attenuations were hyperattenuating in 9 patients, isoattenuating in 1 patient and hypoattenuating in 7 patients.The contrast enhancement degree was mild in 1 patient, moderate in 6 patients and marked in 10 patients.The contrast enhancement pattern was homogeneous in 8 lesions and heterogeneous in 9 lesions.All patients were positive for melanoma(12 cases were positive for HMB-45, 3 cases were positive for melan A, and 2 cases were positive for both). The mean follow-up period was 28.5 months (ranged 2-126 months), and 15 patients were alive with no evidence of disease at the time of the last follow-up, 1 patient exhibited local recurrence and lung metastases, and another 1 patient developed distant metastasis. Conclusion Renal EAML has a range of imaging appearances.Our data suggested that the majority of the tumors (size 10 cm) were solid and had a tendency to be hyperattenuating on unenhanced CT images.Hemorrhaging or necrosis was observed in tumors with sizes≥10cm with heterogeneous enhancement.In contrast to classic AML, which is benign, EAML is potentially malignant and exhibits aggressive clinical features, including local recurrence and distant metastasis.

[Abstract] Objective: To investigate the mechanisms of carnitine palmitoyltransferase 1c (CPT1c) expression to affect the proliferation and apoptosis of human thyroid papillary cancer B-CPAP cells through the AMP-dependent/activated protein kinase (AMPK) pathway in the low glucose and hypoxic conditions. Methods: Firstly,humanthyroidpapillarycarcinomaB-CPAP cells were cultured under normal condition or low glucose and hypoxic condition respectively, followed with the treatment of AMPK inhibitor compound C. Western blotting was used to detect the expressions of AMPK, p-AMPK, peroxisome proliferator-activated receptor α (PPARα) and CPT1c; the proliferation and apoptosis were detected by CCK-8 and Flow cytometry, respectively. Then PPARα-siRNA was synthesized and transfected into B-CPAP cells to knock down PPARα, and then the cells were cultured under normal or low glucose and hypoxic condition respectively.Above indicators were also detected to verify the regulation of PPARα on CPT1c. Finally, the human luciferase reporter plasmid containing CPT1c gene promoter was constructed, and the effect of PPARα on the activity of CPT1c promoter luciferase activity was observed by immunofluorescence. Results: The expressions ofAMPK, p-AMPK, PPARα and CPT1c were significantly increased in B-CPAP cells under low glucose and hypoxia condition (P<0.05 or P<0.01), while cell proliferation and apoptosis rate did not change significantly (P>0.05). After the treatment of AMPK inhibitor compound C, the expressions of p-AMPK, PPARα and CPT1c in low glucose and hypoxia group were significantly decreased (P<0.05 or P<0.01), the inhibitory rate on cell proliferation and apoptosis rate were significantly increased (P<0.05). However, the change range was smaller than that in the normal culture + compound C group (P<0.05).After PPARα knockdown, the expressions ofAMPK, p-AMPK, PPARα and CPT1c in cancer cells cultured under normal conditions were significantly decreased (P<0.05 or P<0.01), and the inhibitory rate on cell proliferation and apoptosis rate were significantly increased (P<0.05). While under low glucose and hypoxia condition, the expression of CPT1c in cells after transfection was significantly decreased (P<0.05), and the inhibition rate on cell proliferation and the apoptosis rate were significantly increased (P<0.05); However, the change range was still lower than that of normal condition group after transfection (P<0.05).After PPARα overexpression, the ratio of fluorescence in the empty vector group was not significantly different from that of the blank group (P>0.05), and the ratio of fluorescence was significantly increased in PPARα over-expression group (P<0.05). Conclusions: AMPK can increase the expression of PPARα to promote the expression of CPT1c in thyroid cancer B-CPAP cells under low glucose and hypoxia conditions, thereby inhibiting cell apoptosis and maintaining cell proliferation ability.
