Objective Little is known about the effects of antioxidant on the micturition function in diabetic cystopathy .In this study, we investigated the effects of antioxidant sulforaphane on bladder micturition function in diabetes mellitus ( DM)mice with bladder underactivity . Met hods We established DM models in mice by intraperitoneal injection of a single dose of streptozotocin (STZ)at 65 mg/kg and randomly divided them into three groups , sulforaphane treatment (n=10), vehicle treatment (n=10), and DM model (n=10), with another 10 normal healthy mice included as blank controls.At 24 weeks of the experiment, we obtained and analyzed such indexes of mice as the body weight , fasting blood glucose (FBG), 24-hour urine volume (24 h UV) and bladder wet weight ( BWW ) , results of cystometrography , and cystometric parameters including intercontraction interval ( ICI ) , maximum bladder pressure during micturition ( Pmax ) , maximum cystometric capacity (MCC), void volume (VV), post-void residual urine vol-ume (PVR) and residual urine rate (RUR). Results Compared with the blank controls , the DM models with bladder underactivity showed significantly increases in BWW ([67.96 ±2.35]mg), 24 h HU ([22.47 ±1.93]mL), MCC ([0.70 ±0.03]mL), VV (0[.23 ±0.01]mL), PVR ([0.49 ±0.02]mL), RUR ([70.10 ± 0.80]%), and ICI, but a remarkable decrease in Pmax .Sulforaphane treatment significantly reduced BWW ([576.9 ±2.41]mg), 24 h HU ([16.27 ±1.51] mL), MCC ([0.54 ±0.03]mL), PVR ([0.34 ±0.02]mL), RUR ([62.71 ±1.26]%), and ICI of the diabetic mice . Conclusion Sulforaphane could improve bladder micturition function in mice with STZ-induced DM , which might be related to its action mechanism of antioxidative stress damage .

Objective To search for differentially expressed proteins in normal ovaries,benign,borderline and malignant ovarian tumor protein. Methods The protein from ovarial carcinoma tissue and benign ovary was drawn, and analyzed with SELDI-TOF MS. Results There are some high expression proteins in ovarian cancer tissues: M/Z 15 112.15, 15 296.79, 7560.78, 16 049.39, 7682.06, 7932.30,15 851.32, 4619.68 and 8052.10. Borderline ovarian tumor protein peak were between benign and malignant:M/Z 15 112.15, 15 851.32, 7560.78, 7682.06 and 7932.30. Conclusion There were some differentially expressed proteins in different ovarian tissue. They might lay the molecular basis for the clinical diagnosis and therapy of ovarian cancer.

Objective To compare the outcomes between interstitial cystitis/bladder pain syndrome (IC/BPS)patients treated with three-drug combination (M blockers + alpha blockers + Amitriptyline) and Sodium hyaluronate intravesical instillation.Methods The patients who came to Second Affiliated Hospital of Nanjing Medical University during October 2014 to September 2015 were investigated if they had IC/BPS.According to the treatment plan,27 patients (group A) received three-drug combination (M blocker + alpha blockers + Amitriptyline)therapy.Thirty-eight patients recelved instillation of sodium hyaluronate (40 mg/50 ml) therapy (group B).Intravesical instillations were performed weekly in the first 6 weeks,and monthly until sixth month.Interstitial cystitis symptom index,interstitial cystitis problem index,overactive bladder symptom score,visual analogue scale/score,the maximum urination and self-rating depression scale were assessed at baseline and the sixth month.Measurement data were expressed as ((x) ±s),t test was used for comparison between groups,and paired t-test was used for comparison of paired data.Results There were 65 patients.Age range was 25-73 years,course of disease (2-99 months),average age (51.4 ± 13.5),average duration (39.8 ± 31.0) months,of which 9 male (13.8％) and 56 female (86.2％) patients.The group A variation of ICSI、ICPI、OABSS、VAS、SDS and maximum urination were 3.7 ± 2.4、1.3 ± 1.5、1.2 ± 1.3、2.1 ± 1.5、3.1 ± 4.5、74.6 ± 52.4,The variation of group B ware 6.8 ± 3.6、5.0 ± 3.8、2.5 ± 1.8、2.8 ± 1.7、8.9 ± 6.4、109.0 ± 81.1.The improvement in ICSI,ICPI,OABSS,SDS of group B were higher than group A (P ＜ 0.05).Conclusion IC/BPS seriously affect the quality of life and the patients are prone to depression.The sodium hyaluronate intravesical instillation therapy could achieve more effect than the three-drug combination therapy.

Objective:To observe the physiological effect of bi-level positive airway pressure (BiPAP) ventilation among stable chronic obstructive pulmonary disease (COPD) patients.Methods:This was a small sample size, exploratory, interventional study. A total of 10 outpatients with stable COPD were included from Department of Pulmonary and Critical Care Medicine of Zhujiang Hospital, Southern Medical University between January 2018 and December 2018. The BiPAP mode of noninvasive mechanical ventilation was adopted. The inspiratory positive airway pressure was gradually increased from 10 cmH 2O (1 cmH 2O=0.098 kPa) to 24 cmH 2O, and each time by 2 cmH 2O. The expiratory positive airway pressure remained unchanged at 4 cmH 2O. Baseline and test data were collected before and during the ventilation for comparison, including total respiratory cycle time (T tot), inspiratory time (T i), inspiratory time (T e), inspiratory tidal volume (V Ti); mouth pressure (P mo), esophageal pressure (P eso), transdiaphragmatic pressure (P di), esophageal pressure time product (PTP es), diaphragm pressure time product (PTP di), root mean square of electromyography of diaphragm (RMS), V e/RMS, inspiratory capacity (IC), the change in end-expiratory lung volume (ΔEELV) and dynamic PEEPi (PEEPi dyn). Results:All the 10 patients completed the trial. Compared to calm breathing, V Ti, V e, P mo, IC, ΔEELV score and V e/RMS increased significantly with increasing pressure levels (all P<0.05); T e only increased significantly at 20-22 cmH 2O pressure levels compared to calm breathing ( P<0.05). P di, PTP es, PTP di, RMS and RMS/RMS max decreased significantly with increasing levels (all P<0.05). PTP es and PTP di converged to 0 and no longer showed significant changes after the 18 cmH 2O pressure level. RMS and RMS/RMS max flattened out at pressure level greater than 16 cmH 2O. T i/T tot only significantly decreased at the 20 cmH 2O pressure level compared to calm breathing. PEEPi dyn showed a tendency to decrease and then increase with increasing pressure levels. Conclusion:BiPAP ventilation, at appropriate pressure levels, significantly relieves pulmonary ventilation disorders and reduces the load of respiratory muscle in patients with stable COPD.

Objective:To investigate the prognostic factors associated with unresectable (stage Ⅲa-Ⅳ, according to the 7th edition of the AJCC cancer staging manual) lung squamous cell carcinoma.Methods:We retrospectively analyzed 350 patients with inoperable locally advanced, recurrent or metastatic lung squamous cell carcinoma who were admitted to the First Affiliated Hospital of Chinese Medical University from January 2005 to June 2018. The clinical pathological data, treatment and survival follow-up information of the patients were collected. Kaplan-Meier survival was used to compare the overall survival rate of different risk groups. Univariate analysis and multivariate Cox regression analysis were used to determine the independent prognostic factors.Results:A total of 350 patients were enrolled. The median overall survival (OS) of these patients was 16.7 months. Univariate analysis showed the stage, Eastern Cooperative Oncology Group(ECOG), first-line chemotherapy evaluation (RECIST version 1.1), radiation therapy, number of systemic chemotherapy lines, carcinoembryonic antigen (CEA), cancer antigen 125 (CA125), C reactive protein (CRP), lactate dehydrogenase (LDH), whether liver, brain, boneor metastasis were associated with the OS of patients with advanced lung squamous cell carcinoma (all P<0.05). Multivariate analysis showed that ECOG score ( HR=1.855, 95% CI: 1.063-3.239, P=0.030), whether underwent lung resection ( HR=0.476, 95% CI: 0.302-0.751, P=0.001), first-line chemotherapy evaluation [stable disease (SD): HR=0.293, 95% CI: 0.159-0.540, P<0.001; complete response (CR)+ partial response (PR): HR=0.223, 95% CI: 0.120-0.413, P<0.001], CRP ( HR=1.715, 95% CI: 1.080-2.723, P=0.042), LDH ( HR=1.116, 95% CI: 0.780-1.596, P=0.002) and CEA ( HR=1.855, 95% CI: 1.361-2.528, P<0.001) before chemotherapy, liver metastasis ( HR=2.453, 95% CI: 1.461-4.120, P=0.001) are independent prognostic factors for patients with unresectable lung squamous cell carcinoma. Conclusion:The ECOG score, surgical treatment history, first-line chemotherapy, LDH, CEA and CRP before chemotherapy, liver metastasis are independent prognostic factors for patients with advanced lung squamous cell carcinoma.
