Objective To improve the ventilation mode for respiratory failure based on the self-made respirator. Methods For the conscious COPD patients with type II respiratory failure, nasal mask and NEEP ventilation mode were used. Patients breathe in air through the mouth and breathe out through the noses. There is no need of manual control tube to control the negative pressure in the nasal mask. For the non-typical type I respiratory failure, exhaled gas comes out from the one-way channel in the front of the mask, while oxygen for the next breathes is brought into the ball through the tube under it. Results The COPD patients breathe more freely and smoothly without disturb of the manual control tube. On the non-typical type I respiratory failure, FiO2 is much higher and without breath in CO2. Conclusion The new ventilation mode can provide a great range of FiO2 and get ride of redundant CO2. It's beneficial to the recovery of patients.

This study was aimed to explore the efficacy of establishing and implementing individual healthy di-ets on patients with early diabetic nephropathy ( DN ) . A total of 120 patients with early DN of our hospital were randomly divided into two groups , which were the experimental group and the control group . There were 60 cases in each group . All patients received routine treatment . The fasting blood glucose and 24-hour uri-nary protein were measured pre-treatment , 2-week , 2-month , and 6-month after treatment . Patients in the experimental group were required to receive individual healthy diet therapy as well as routine treatment . The fasting blood glucose of both groups was compared in each stage . The fasting blood glucose of the experimental group was lower than that of the control group after 2-week treatment . After 6-month treatment , the fasting blood glucose of the experimental group was lower than that of pre-treatment . However , there was no obvious difference in the control group compared to that of pre-treatment . There were significant differences on the number of cases with fasting blood glucose below the level of 7.0 mmol/L in different stages of both groups. The 24-hour urinary protein of both groups was also compared in each stage . After 2-week treatment , there was no distinct difference on the 24-hour urinary protein in each stage of both groups . However , after 6-month treatment , the urinary protein of the experimental group , compared to pre-treatment , indicated striking difference , while the control group did not show any difference . It was concluded that individual healthy diet has a significant efficacy in the treatment of early DN , especially in reducing and controlling fasting blood glucose. After carrying out the treatment for 6 months, healthy diet also takes on distinct effects in cutting down 24-hour urinary protein and keeping the glycosylated hemoglobin below 6 . 5%.

Objectives:To validate the Chinese version of the Ureteral Stent Symptoms Questionnaire(Chinese-USSQ) in patients with an indwelling ureteral stent.Methods:The original USSQ was translated into Chinese and linguistically validated following the cross-cultural adaptation of health-related quality of life measures.A total of 83 patients (cases) with indwelling ureteral stent and 90 healthy subjects (controls) were asked to complete the Chinese-USSQ as well as European Quality of Life Visual Analogue scale(EQ-VAS)(for both genders), the International Prostate Symptom Scale (IPSS) (for male), and Urogenital Distress Inventory-6 (for female). Patients were evaluated at weeks 1 and 4 after stent placement and at week 4 after removal. The psychometric properties of the questionnaire were analyzed.Results:The Chinese version of USSQ include 43 items, which addressed various domains of health(6 sections) covering urinary symptoms, pain, general health, work performance and sexual matters with additional problems. A total of 78 patients(45 males and 33 females) and 90 controls (41 males and 49 females)were included for analysis. Internal consistencies (Cronbach′s α coefficients: 0.60-0.78) and test-retest reliability (Spearman correlation coefficient: 0.69-0.91) were satisfactory for urinary symptom, body pain, general health, and work performance domains. Most USSQ domains showed moderate correlations with each other. The convergent validity determined by correlation between other instruments and corresponding USSQ domain was satisfactory. At week 4 it was moderate for the urinary symptoms index compared to the IPSS in men(Spearman correlation coefficient>0.60), for the urinalry symptoms index compared to the UDI-6 score in women(Spearman correlation coefficient 0.52).Sensitivity to change and discriminant validity were also good in most domains ( P<0.01). Only a small proportion of the study population had an active sexual life with the stent in situ, which limited its analysis. Only 1(1.3%) and 6(7.7%) patients had an active sex life at week 1 and 4 after stent placement; meanwhile, 34(43.6%) patents were sexually active at week 4 after stent removal. Conclusion:The Chinese version of the USSQ is a reliable and valid instrument that can be used for Chinese patients with a indwelling ureteral stent in the clinical and research settings.
