Objective To investigate the self-efficacy levels and its influencing factors of community-based patients with chronic obstructive pulmonary diseases (COPD).Methods From October 2008 to March 2009,320 community COPD patients were recruited from a Shanghai community.They undertook questionnaires,scale survey and pulmonary function testing so as to investigate the influencing factors of self-efficacy.Results The total scale of self-efficacy was 74.24 ± 9.50 and the level of selfefficacy in 286 cases( 89.4％ )was intermediate.The knowledge of COPD,social supports,forced expiratory volume at 1 second (FEV1)/forced vital capacity (FVC) and self-management level were entered into regression equation and could explain 57.1％ of the total variance of independent variables.Conclusions The knowledge of COPD,social supports,FEV1/FVC and self-management level are the major influencing factors of self-efficacy in the COPD patients.We should improve the knowledge of disease and strengthen the psychological care and social supports so as to improve their quality of life.

Objective To explore the relationship between self-efficacy and self-management behaviors of patients with chronic obstructive pulmonary disease (COPD).Methods A total of 350 COPD patients form 5 residents' committees in shanghai were recruited by using a convenient sampling method and were scored using Chinese Self-efficacy Scale (CSES)and the self-management behaviors scale.Spearman's correlation analysis was performed to detect the relation of self-efficacy with self-management behaviors.Results Three hundred and twenty adults were included in this investigation,and their average FEV1/FVC was (57.86 ± 7.06)％,average score of self-efficacy was 74.2 ± 9.5.In self-management behaviors,time spent on physical exercise was (16.2 ± 33.9) minutes per week,and endurance exercises accounted for (109.0±49.0) minutes per week.The score of cognitive symptom management practice was 0.9 ± 1.0 and communication with physicians was 0.7 ± 0.8.Total score of self-efficacy was positively correlated with self-management behavior in each dimension (r values were 0.522,0.407,0.330 and 0.044,respectively ; all P ＜ 0.01).Conclusions Self-efficacy and self-management behaviors of COPD patients need to be improved,and self-efficacy may be related to self-management behaviors.

Objective To investigate the efficiency and safety of intervention with flexible bronchoscope under general anesthesia by using laryngeal mask in patients with severe tracheal stenosis induced respiratory failure.Methods A total of 16 in-patients with respiratory failure caused by severe tracheal stenosis admitted from September 2009 to March 2012 were retrospectively reviewed.A comprehensive bronchoscopic intervention for the complete patency of airway was successfully performed with various techniques such as cryotherapy,electrocautery,balloon dilatation,and implantation of selfexpanding metal stents under genersl anesthesia by using laryngeal mask.The efficiency of comprehensive bronchoscopic intervention and dyspnea score were evaluated by chest CT scan and bronchoscopic examination before and after the treatment.Data were expressed as ((x-)± s).Paired t test was used for statistical analysis of the data.Results The degrees of tracheal stenosis and dyspnea score before and after intervention were (85.0±8.4)％ vs.(20.9±7.6)％ (P＜0.01) and (3.9±0.3vs.2.4±0.5,P＜ 0.01),respectively.There were no life-threatening complications occurred including massive haemorrhage.Conclusions It is an effective and safe technique to resolve the tracheal stenosis-induced respiratory failure with intervention by using flexible bronchoscope under general anesthesia with laryngeal mask,and it is a promising interventional treatment for clinic application.

Objective To investigate the correlation of serum uric acid (SUA) level with the prevalence of metabolic syndrome (MS). Methods A random, multi-stage cross-sectional study was performed in 2364 resuden, aged from 20 to 74, in Lanzhou, Gansu province.The resudents were divided into groups according to the level of SUA or 4 components of MS. The relationship between SUA and MS was analyzed. Results The overall morbidity of MS was 20.13 % in Lanzhou , and the morbidity of MS was higher in female than that in male (23.22% vs. 17.37%, P < 0.05);The prevalences of MS was higher in the hyperuricemia (HUA) people than that in the healthy people (32.40 % vs. 17.70 %,P < 0.05); With the increase of SUA level, the morbidity rates of MS and its components increased;The risk of MS showed a gradual increase with the SUA level, the risk of MS(odds ratio,95%CI)in sex-specific quartiles of SUA was 2.33(1.45 ~ 3.71),2.33(1.45 ~3.71),2.44(1.53 ~ 3.89)in male;and 1.58(0.97~2.56),2.54(1.60 ~ 4.00),5.29(3.41 ~ 8.22)in female. The more the components of MS , the higher the SUA level was found for both the male and the female subjects , with the higher rate of HUA morbidity(P < 0.05). Conclusion There is a significant association between SUA level and MS, as well as the MS components. Comprehensive prevention and control should be taken for the reduction of the risk factors, and much attention should be paid to monitor the SUA level.

Objective To explore the application of continuous subcutaneous insulin infusion (CSII) in elderly type 2 diabetic patients. Methods Elderly group(n = 415) and control group (n= 461) received the transient CSII intensive treatment. The different regiments and the incidence of hypoglycemia were observed between the two groups. Results The average duration reaching the target blood glucose and the insulin dosage at the target time were similar between the two groups (P>0.05). The insulin basal rate in the elderly patients was lower than that in control group. The incidence of hypoglycemia, especially at night, was significantly higher in the elderly patients.Conclusions CSII could control blood glucose effectively in elderly type 2 diabetic patients, but the basal insulin dosage should be decreased to reduce the risk of hypoglycemia.

Objective To study the regiments of continuous subcutaneous insulin infusion (CSII) in admitted type 2 diabetic patients, and to analyse the factors related to its effectiveness and insulin dosage. Methods A total of 1 276 type 2 diabetic patients were treated by CSII. The total efficacy of CSII was evaluted. The use of CSII was also analysed in the newly diagnosed patients, elderly patients, and patients with obese or infectious disease. Results The excellent control of blood glucose were achieved in (5.7±2.6)days in the dosage more early and quickly in the newly diagnosed group than that in the previously diagnosed group after the blood glucose levels achieved good control. The percentage of the patients reached the clinical relieve was also higher in the newly diagnosed group. The incidence of hypoglycemia was significantly higher in the elderly patients with lower basal insulin dosage at night. The bolus insulin dosage in the obese patients was higher than that in the non-obese patients. The patients with infectious disease usually have a higher basal insulin dosage than those without infectious disease. The days needed for achieving good control of blood glucose and the insulin dosage were related to infectious factors, the basal blood glucose and obesity. Conclusion The application of CSII among the patients is varied with different conditions. Blood glucose level, body mass index and infection factors are important to determine the initial insulin dosage.

Objective To investigate the expression variation of aquaporin in colon tissues in acute necrotizing pancreatitis (ANP).Methods ANP rat model was induced by the retrograde injection of sodium taurocholate into the biliopancreatic duct.The rats were killed at 4 h, 8 h, 12 h and 24 h after modeling with 6 rats for each time point.The pancreas and colon tissues were harvested for pathological examination.The levels of IL-6, TNF-α mRNA expression and AQR (aquaporin-3, aquaporin-4, aquaporin-8) mRNA expression in proximal and distant colon were detected by RT-PCR.The levels of aquaporin protein in colon were examined by immunohistochemistry.Results After the establishment of ANP SD rat model, the integrity of colonic mucosa was continuously damaged, the structure of epithelial cells was unclear and the colonic villus were broken and destroyed, and inflammatory cell infiltration in submucosa was observed.The pathological score increased with the time of modeling.In 4 h, except that the mRNA levels of AQP-4 in distal colon was not obviously changed, mRNA levels of IL-6 and TNF-α, mRNA and protein expression of AQP-3 and AQP-8 in the proximal and distal colon of ANP rats were significantly elevated compared with shame group (P<0.05).AQP-3 and AQP-8 mRNA in proximal colon of ANP rats reached its peak in 8 h after the establishment and AQP-4 mRNA peaked at 24 h.AQP-3 and AQP-4 mRNA in distant colon of ANP rats reached its peak in 8 h after the establishment and AQP-8 mRNA peaked at 24 h.Protein expression of AQP-3, AQP-4 and AQP-8 in proximal and distant colon was strongest in 12 h and 24 h after the establishment.Conclusions With the progression of the ANP, the expression levels of AQP-3, AQP-4 and AQP-8 in both proximal and distal colons were elevated in various degrees, indicating that the aquaporins may participate in water metabolism of colon during ANP.

Objective:To explore the feasibility, safety and clinical efficacy of ileum augmentation cystoplasty assisted by Da Vinci robot for the treatment of neurogenic bladder.Methods:Retrospective analysis was performed on the data of 12 patients with neurogenic bladder admitted to Zhejiang Provincial People’s Hospital from March 2017 to November 2018, including 11 males and 1 female, with the mean age of 38(12-67). Preoperative symptoms were urinary incontinence, dysuria, decreased bladder capacity, or increased bladder pressure leading to ureteral reflux. All the 12 patients underwent preoperative intermittent catheterization, including 8 patients with spinal cord injury and 4 patients with spinal cord dysplasia. Preoperative serum creatinine(129.58±44.60)μmol/L and total glomerular filtration rate(61.63±18.04)ml/(min·m 2) were observed in 12 patients. Preoperative urodynamic examination showed the safe bladder volume of (95.67±39.10)ml, bladder internal pressure of(63.30±6.02)cmH 2O(1 cmH 2O=0.098 kPa)at the end of filling period, bladder compliance of(10.24±1.14)ml/cmH 2O, residual urine volume of(152.58±80.89)ml, and urine flow rate of(3.88±3.63)ml/s. Bladder contracture was evident on preoperative cystography. Ultrasound examination showed different degree of hydronephrosis and ureter expansion, in all cases, with ureteral reflux grading Ⅰin 2 cases, grade Ⅱ in 4 cases, grade Ⅲ in 4 cases, grade Ⅳ in 2 cases. All the 12 patients underwent robot-assisted ileum augmentation cystoplasty with 5-point puncture. Transverse incision of the bladder wall before full thickness, according to the amount of bladder and quality to decide 30 cm(normal), longitudinal cut back loops and one point after suture fixation in the bladder wall midpoint, fixed point as starting point, in turn, will be blind to the bladder stitching on both sides, the bilateral ureteral placing a single J tube respectively, evaluation of surgical success rate (including intraoperative bleeding, interception of bowel loops are no damage adjacent viscera, ureter openings with and without damage, impermeability, match insufflate whether unobstructed), postoperative complications, anastomotic fistula, intestinal obstruction, abdominal bleeding), urine dynamics test parameters, and patients’ quality of life. Patients were regularly given anticholinergic drugs(2 mg/d) for 6 months after surgery. Results:All the 12 cases in this group were successfully completed without any transfer to open surgery. The operation time was(120.8±12.0)min. Intraoperative blood loss(84.0±23.2)ml. Postoperative intestinal function recovery time(3.3±1.3) d. Postoperative hospital stay(12.1±3.1)d. Postoperative pelvic drainage tube indwelling time (3.8±1.2) d. Catheter and single J tube were removed 2 weeks after operation. Postoperative follow-up averaged 19.4(3-24) months. At 3, 12, 24 months after surgery, the bladder safety volume was rechecked(435.83±33.56), (450.90±31.09), (462.00±33.72)ml, the bladder internal pressure at the end of filling was(18.60±0.92), (15.70±1.42), (12.96±1.34)cmH 2O, the blood creatinine level was(81.43±21.10), (74.34±15.70), (72.90±15.90)μmol/L, and the bladder compliance was(37.94±4.22), (40.40±3.98), (43.42±4.20)ml/cmH 2O and the total glomerular filtration rate(91.52±9.49), (102.18±5.65), (112.41±6.50)ml/(min·m 2) were significantly improved compared with those before surgery( P<0.001). After 24 months of bladder urination training, 1 patient could basically urinate by herself. Three patients were treated with intermittent urinary catheterization supplemented by automatic urination. The remaining 8 patients were completely dependent on urinary catheter for intermittent catheterization. Postoperative complications such as anastomotic fistula, ileus and abdominal bleeding were not found in 12 patients. Conclusions:Ileum bladder enlargement assisted by robot can effectively expand bladder volume, reduce bladder internal pressure, improve bladder compliance, prevent ureteral reflux and protect renal function.
