Objective To evaluate the clinical value of interventional chemotherapy and intravesical instillation for preventing postoperative recurrence and metastasis of cancer in urinary bladder.Methods One hundred and eight patients with urinary bladder cancer were divided into group A and group B.Intravesical instillations after surgical operation were performed in group A (n=52) and combined interventional chemotherapy and intravesical instillations after operation were performed in group B (n=56).The patients were followed up for 1 - 3 years.Results In group A,recurrence occurred in 5 cases (9.62%) within one year,and in 23 cases (44.23%) within 3 years after the operations metastasis developed in 21 cases (40.38%),and 18 cases (34.62%) died.In group B,recurrence occurred in 2 cases (3.57%) within one year,and in 11 cases (19.64%) within 3 years after the operation;metastasis developed in 7 cases (12.50%), and 5 cases (8.93%) died.There were statistical significant differences in recurrence,metastasis and mortality between these two groups (P

Objective To compare the safety and effectiveness of disposable circumcision suture device (DCSD) with conventional circumcision in surgical treatment of phimosis and redundant prepuce . Methods One hundred and sixty one patients with phimosis or redundant prepuce were randomly assigned to be treated by circumcision using disposable circumcision suture device ( DCSD group , n =89 ) or conventional circumcision (CC group,n =72),respectively.Results The operation time was (3.8 ± 0.5)min in DCSD group and (31.6 ±2.7)min in CC group (F=71.21,P=0.000),blood loss was 1.0(0.9, 1.2)ml in DCSD group and 6.2(5.7, 7.0)ml in CC group (Z =-10.90,P=0.000).There were no significant differences in intraoperative pain score (1.4 ±0.6 vs.2.9 ±0.8, F=2.08, P=0.151) and wound healing time [(14.0 ±1.3) vs.(16.8 ±2.1) d, F=0.10, P=0.754] between two groups.There was no need to change the dressing for patients in DSCD group 3 days after the operation , while patients in CC group changed dressing 3 times after the operation .No significant differences in postoperative complication rate [10%(9/89) vs.4%(3/72),χ2 =2.04,P=0.153] and satisfaction rate with the penile appearance [98%(87/89) vs.94%(68/72), χ2 =0.47,P=0.494] were found between two groups .Conclusion DCSD exhibits superiority over CC for shorter operation time and less blood loss in circumcision .

The clinical and pathological data of 6 patients with urahcal adenocar,cinoma of the bladder admitted in Beijing Luhe Hospital from 1996 to 2016 were analyzed and relevant literature was reviewed.Urachal carcinoma accounted for 0.66% of the bladder cancers admitted at the same period (6/906) and 6/16 of the bladder adenocarcinomas.Painless hematuria was the most common symptom.One patient had extensive metastasis as shown in biopsy and died 6 month after the diagnosis.Two patients underwent partial excision of bladder with no tumor recurrence.One patient underwent partial cystectomy followed by chemotherapy and radiotherapy, recurrence occurred one year later and he then received radical cystectomy.Another 2 patients underwent laparoscopic cystectomy and en bloc resection of umbilical ligament and umbilicus, and no recurrence was found in the follow-up for 6 years and 15 months, respectively.Pathological and immunohistochemistry are essential for the diagnosis of urachal adenocarcinoma.As it is not sensitive to radiotherapy or chemotherapy,surgery is the preferred treatment for patients with early stage diseases.Individual anticancer therapy may be the trend of treatment.

Objective To investigate the effect of dexmedetomidine combined with butorphanol conventional therapy on sustaining sedation of intensive care unit (ICU) patients.Methods Sixty critically ill patients in Binzhou Central Hospital from June to September in 2014 were randomly divided into experimental group and control group, 30 cases in each group. In the control group, 0.8 mg/L dexmedetomidine hydrochloride injection (400μg with addition of 46 mL normal saline to form 50 mL solution) was intravenously infused continuously at a speed of 0.4μg·kg-1·h-1 by a micro-pump to induce analgesia and sedation; while in the experimental group, dexmedetomidine combined with 200 mg/L butorphanol (10 mg plus 40 mL normal saline to form 50 mL solution) was given for intravenous infusion by a micro-pump with a speed of 0.01 mg·kg-1·h-1 to maintain analgesia and sedation for 48 hours whose required Ramsay score in both groups was 3 - 5. Before and after treatment, the changes of heart rate (HR), respiratory rate (RR), mean arterial pressure (MAP), arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2), and the pulse oxygen saturation (SpO2) of both groups were observed. The dosage of dexmedetomidine used for maintenance of required analgesia and sedation and FPS (facial expression) grading and Ramsay score were compared respectively between the two groups, and the clinical efficacy of the two groups were evaluated.Results After treatment, the HR, MAP, RR in both groups were significantly lower, and PaO2 and SpO2 were significantly higher than those before treatment, and the degrees of improvement in the above indexes of the experiment group were superior to those of the control group [HR (bpm): 84.58±12.43 vs. 118.62±14.21, MAP (mmHg, 1 mmHg = 0.133 kPa): 82.35±12.12 vs. 92.35±12.32, RR (times/min): 25.42±3.98 vs. 32.87±5.12, PaO2 (mmHg): 95.21±10.55 vs. 75.18±8.57, SpO2: 0.981 4±0.102 8 vs. 0.954 7±0.093 8, allP < 0.05]. The total therapeutic effect in experiment group was significantly higher than that in control group [93.3% (28/30) vs. 76.7% (22/30),P < 0.05]. The dexmedetomidine dosage used in the experiment group was much less than that in the control group (μg/d: 412.12±23.18 vs. 520.05±15.68,P < 0.05). The FPS score in the experiment group was obviously lower than that in the control group (1.48±0.16 vs. 2.52±0.74,P < 0.05).Conclusion In comparison, to achieve sustained and required analgesic and sedative effect for ICU patients by combined use of dexmedetomidine and butorphanol, the dosage of dexmedetomidine used is less than dexmedetomidine applied alone, in addition, the combined use can achieve better Ramsay grading, steady blood pressure and excellent effect.

E-cadherin is a key epithelial protein and adhesive molecule. This study detected the E-cadherin expression in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and controls, and analyzed its possible role in the pathogenesis of CRSwNP. The expression of E-cadherin was detected by using Western blotting and immunohistochemistry in controls and patients with CRSwNP. Computed tomography (CT) scan findings were scored. The results showed that the E-cadherin expression was up-regulated in patients with CRSwNP as compared with controls (P=0.039) and the positive staining was predominantly localized on the epithelial cell membrane. E-cadherin level was correlated negatively with Lund-Mackay scores in patients with CRSwNP (r=-0.604, P=0.005). It is suggested that E-cadherin may be involved in the pathogenesis of CRSwNP and correlated with disease severity.

Objective To observe the expression of cardiotrophin-1(CT-1) in ischemia-reinfusion cardiac muscle of rats and the effect of neuregulin-1(NRG-1).Methods The model of ischemia-reinfusion cardiac muscle of rats were prepared,35 rats were randomly divided into 4 groups:model group(n=8),NRG-1 pretreatment group(n=9),pseudo-surgery group(n=8) and normal control group(n=10).The CT-1 mRNA in the observed cardiac muscle of all groups was measured by RT-PCR and the relative amount of CT-1 mRNA were calculated,and for statistical treatment.Results The CT-1 mRNA of model group was(63.96?9.34),and it was higher than that of pseudo-surgery group(36.16?5.43)and normal control group(36.84?4.64).The significant differences were found in 3 groups(F=47.37 P

OBJECTIVE To understand the effects of meropenem on the biofilms of Pseudomonas aeruginosa lasR/rhlR mutations in vitro.METHODS The biofilms of PAEO1 and its lasR,rhlR,and lasR rhlR mutants were incubated in a polyvinyl chloride tube in 0.9% saline for three days,then were immersed in meropenem solution of 26 ?g/ml for 24 hours,and examined by scanning electron microscopy(SEM).RESULTS After three days incubation,PAEO1 biofilms showed a well-developed structure,however,the biofilms of PAEO1 lasR,rhlR,and lasR rhlR mutants were thin and poor developed;after 24 hours in meropenem solution,PAEO1 biofilm become rareness,whereas PAEO1 lasR,rhlR,and lasR rhlR mutants biofilms were almost destructed and only small pieces left.CONCLUSIONS lasR/rhlR Genes play probably an important role in the formation of P.aeruginosa biofilm and in the resistance to meropenem.
