ABSTRACT
Objective To compare health related quality of life (HRQOL) between modified and traditional cutaneous ureterostomy, and explore the reasons for these differences, in order to provide the basis of HRQOL for the choice of cutaneous ureterostomy. Methods A total of 53 patients underwent cutaneous ureterostomy were selected, and the patients were divided into traditional cutaneous ureterostomy group (traditional group, 21 cases) and modified cutaneous ureterostomy group (modified group, 32 cases) according to the surgery method. The patients were evaluated by functional assessment of cancer therapy-bladder (FACT-BL), and the HRQOL was compared between 2 groups. Results There were no statistical differences in HRQOL score at 1, 3, 6 and 9 months after surgery between 2 groups (P>0.05). The HRQOL score at 12 months after surgery was significantly higher in modified group than that in traditional group:(141.5 ± 10.4) scores vs. (123.1 ± 5.2) scores, and there was statistical difference (P0.05). But the scores of functional status and bladder cancer special scale (BSS), total score of FACT-BL in modified group were significantly higher than those in traditional group:(26.0 ± 2.5) scores vs. (23.8 ± 3.5) scores, (46.7 ± 6.2) scores vs. (34.8 ± 5.5) scores, (143.9 ± 15.7) scores vs. (117.5 ± 8.1) scores, and there were statistical differences (P<0.01). Conclusions The HRQOL at 12 months after surgery in modified cutaneous ureterostomy is better than that in traditional cutaneous ureterostomy. Therefore, if the patient's physical condition permits, priority should be given to modified cutaneous ureterostomy to reduce the complications and improve the quality of life.
ABSTRACT
Objective To compare the clinical therapeutic effect of percutaneous nephrolithotomy (PCNL) and flexible ureteroscope lithotripsy (FUL) for unilateral lower-calyceal calculi with the diameter of 10-20 mm. Methods The clinical data of 65 patients with unilateral lower-calyceal calculi with the diameter of 10-20 mm were retrospectively analyzed. Thirty cases were treated with PCNL (PCNL group), and 35 cases were treated with FUL (FUL group). The operative time, success rate of lithotomy, haemoglobin decrease after operation, postoperative hospital stay, hospitalization expenses and complication were compared between 2 groups. Results Treatment was completed successfully in the patients of 2 groups, without ureteral perforation, avulsion and other serious complications intraoperatively and postoperatively. There were no statistical differences in success rate of lithotripsy, incidence of high fever after operation and postoperative analgesia rate between 2 groups (P>0.05). The operative time and hospitalization expenses in FUL group were significantly higher than those in PCNL group:(95.27 ± 22.69) min vs. (62.25 ± 20.73) min and (17 242 ± 2 679) yuan vs. (14 205 ± 1 654) yuan, and the haemoglobin decrease after operation and postoperative hospital stay time were significantly lower than those in PCNL group:(0.67 ± 0.33) g/L vs. (7.98 ± 4.33) g/L and (3.75 ± 0.78) d vs. (6.54 ± 1.68) d, and there were statistical differences (P<0.05). Conclusions For the treatment of lower-calyceal calculi with the diameter of 10-20 mm, the success rates of lithotripsy of PCNL and FUL are similar. FUL has less trauma, with shorter postoperative hospital stay time, but the cost is relatively high.
ABSTRACT
Objective To assess the perioperative change in Quality of Life(QoL)in patients who underwent CABG surgery. Methods The Chinese version of the SF-36 and SAQ were sent to participants at baseline and three and six months after CABG sur- gery.Results Angina stability score,one of the five SAQ domains,was lowest and postoperative SAQ domains scores were with sig- nificant improvement from baseline.Many of the dimensions of the SF-36 in postoperative patients were better than baseline.The SF- 36 was also used to evaluate in groups ONCAB and OPCAB,but no difference of the SF-36 subscale scores between the two groups was observed.Conclusion SAQ domains scores were significantly improved in three months and increased further in six months.Many of the dimensions of the SF-36 in postoperative patients were improved than baseline.No difference of the SF-36 subscale scores between the groups of ONCAB and OPCAB was observed postoperatively.
ABSTRACT
Objective To study the imaging diagnosis of tumors and tumor-like lesion of fibrous histiocyte origin in the femora.Methods Imaging features of femoral fibrous histiocyte neoplasm and tumor-like lesion were restrospectively analyzed in 17 cases ,including 16 cases proved by surgery and pathology, and one case was follow-up studied in five years.All cases were examined by plain X-ray flim, CT scan in 5 cases. Results There were fibrous dysplasia of bone in 8 cases,non-ossifying fibroma in 5cases ,fibrosarcoma of bone and benign fibrous histiocyte tumor of bone in 1 case respectively ,malignant fibrous histiocyte tumor of bone in 2 cases. They were diagnosed correctly before operation in 13 cases (13/17,76.5%) and misdiagnosed in 4 cases.Conclusion The most of femoral fibrogenic tumor and tumor-like lesion can be dingnosed correctly before operation ,because of they are of specific imaging features, while femoral fibrous histocyte original tumors are not of specific imaging findings, it must combine with clinical and pathologic data in diagnosis.
ABSTRACT
Based on the body height and weight of the Chinese young men, 975 from the north and 921 from the south of China, actually measured, a calculating formula for the ideal body weight of young men both of north and south listed blow was established. The Northener's ideal body weight (kg) = [height (cm) - 150] ? 0.6 +50; the Southener's ideal body weight(kg) = [height (cm.) - 150] ? 0.6 +48. The formula later checked by another data of body height and weight of 783 young men from north and 883 from south has been proved to be reliable. It also showed that the ideal body weight of 1464 young men from north and 2264 from south calculated according to the formula seemed to be more reasonable than the another's formula used previously.
ABSTRACT
35 rats were divided into 5 groups. Group 1-3 were fed rations containing 20, 12 and 6% caseien respectively, group 4 containing 12% mixed protein of soybean and gluten. The food of group 5 was the same as that of group 1 but the amount was only half of that of group 1. Every animal was given 8?g vitamin A by stomach tube daily for 3 weeks and then 25?g for 2 weeks. Afterward serum vitamin A values were determined in all animals, then 132?g vitamin A was administrated by stomach tube. After 3.5 hours, the vitamin A values in serum and liver were determind. The results showed that in group 3 and 5 serum vitamin A contents decreased and the liver values rose. It was suggested that the release of vitamin A from liver had been interfered by semistarvation or low protein intake. There is no difference between group 2 and 4.
ABSTRACT
An improved microfluorimetric method for determination of serum vitamin A was presented. In this method, the excitation wavelength 345nm and emission maximum 480nm were selected, and cyclohexane as solvent for extraction of saponified vitamin A in the serum samples to be tested was used. The sensitivity was sufficient for measurement of vitamin A content in 20*l serum taken from normal fasting blood without elimination of interference. The recovery averaged 99.0% (93.0-105.5).When this method was applied to laboratory study or field work, practically, the results showed that the values of vitamin A obtained seemed to correlate with its nutritional status of experimental animals or subjects investigated. The procedure was simple, reproducible and easily acceptable, espicially in the field work.
ABSTRACT
Ninety rats were divided into 8 groups. Group 1-5 were fed vitamin A free ration and each group was divided into 2 subgroups at the beginning and 12, 23, 36, 43, days after the experiment respectively. Group 6-8 were fed the ration containing 66, 132, and 198?g vitamin A per 100g diet respectively fer 30 days, and each group was also divided into 2 subgroups. The results showed that RBPR% was better than the serum vitamin A content in evaluating vitamin A nutritional status. It was suggested that the vitamin A nutritional status could be graded as follows: deficient(abore 70%)) mar-ginal(60-70%),normal (20-60%), and sufficient (under 20%)by RBPR%.
