Objective To investigate the clinical effects of different urinary diversion regimens after minimally invasive resection of bladder cancer. Methods 127 patients with muscular infiltrating bladder cancer from January 2010 to June 2015 were enrolled in this study. According to the patients' condition, they were divided into orthotopic ileal cystectomy group (58 cases), Bricker bladder surgery group (33 cases), ureteral skin ostomy group (36 cases), then compare the clinical data, postoperative complications and quality of life of the three groups. Results There was no significant difference in the ratio of sex, the distribution of age and tumor staging among the three groups. The operation time and postoperative hospital stay in orthotopic ileal cystectomy group were longer than those in the other two groups. The operation time and postoperative hospital stay of the Bricker bladder surgery group were longer than that in ureteral skin ostomy group, the difference was statistically significant; the bleeding in orthotopic ileal cystectomy group was more than the other two groups, and in Bricker bladder surgery group was more than ureteral skin ostomy group, the difference was statistically significant. There was no significant difference in the recovery time of intestinal function among the three groups. The recovery time of intestinal function in ureteral skin ostomy group was shorter than that in the other two groups, the difference was statistically significant. There was no significant difference in the incidence of short-term complications of the three groups of patients. The incidence of long-term complications of orthotopic ileal cystectomy group was significantly higher than the other two groups, the difference was statistically significant. The social function scores, and overall health score of orthotopic ileal cystectomy group were higher than the other two groups, the difference was statistically significance. Conclusion Without external device, closer to the characteristics of physiological urination, orthotopic ileal cystectomy holds higher postoperative quality of life, and higher incidence of long-term complications. With advantages of quick recovery and less complications, ureteral skin ostomy is best for patients who can not stand for long time surgery. It should choose the appropriate surgical approach for patients according to individuals' conditions.

To compare transient elastorgaphy (FibroTouch) and acoustic radiation force impulse (ARFI) in diagnosis of liver fibrosis in patients with chronic hepatitis B.One hundred and forty five patients with chronic hepatitis B underwent FibroTouch and ARFI examinations in Xixi Hospital of Hangzhou from January to November 2015. The liver stiffness (LSM) was detected by FibroTouch and the liver shear wave velocity (VTQ) was detected by ARFI; liver biopsy was performed in all patients. With biopsy results as gold standards, the diagnostic values of FibroTouch and ARFI for liver fibrosis were analyzed with Spearman correlation analysis and receiver operating characteristic (ROC) curve.The correlation coefficient of FibroTouch and ARFI was 0.746 (<0.01). FibroTouch and ARFI were significantly correlated with pathological stage determined by liver biopsy(=0.705 and 0.727, all<0.01). When 8.4 kPa was taken as the cut-off value of LSM and 1.49 m/s was taken as the cut-off value of VTQ, the areas under ROC (AUCs) were 0.857 and 0.836 (>0.05) in diagnosis of fibrosis S≥2 stage; when 10.8 kPa of LSM and 1.49 m/s of VTQ were used as cut-off values, the AUCs were 0.872 and 0.881 (>0.05) in diagnosis of S≥3 stage; when 12.3 kPa of LSM and 1.81m/s of VTQ were used as cut-off values, the AUCs were 0.875 and 0.888 (>0.05) in diagnosis of S=4 stage.Both FibroTouch and ARFI can be effectively used in evaluation of liver fibrosis in patients with chronic hepatitis B.

OBJECTIVE:
To explore the clinical value of virtual touch tissue quantification (VTQ) technique and the PGA index [prothrombin time (P), γ-glutamyl transpeptadase (GG) and apolipoprotein A1 (ApoAl)] in evaluating the degree of liver fibrosis in alcoholic patients.
METHODS:
A total of 64 patients with long-term alcohol history were enrolled for this study. The liver ultrasonography elasticity was examined by VTQ techniques, the VTQ value was assessed in the liver target region, and then the PGA index was calculated. According the liver biopsy biological results, a golden standard, the patients were divided into a non-fibrosis group (n=11), a fibrosis group (n=10), a significant fibrosis group (n=14) and a cirrhosis group (n=29). The diagnostic value of VTQ and PGA index were compared in alcoholic patients following the classification of liver fibrosis.
RESULTS:
The elastography VTQ values were (1.38±0.33), (1.49±0.30), (1.76±0.22) and (2.28±0.53) m/s; while the PGA indexes were 2.09±0.94, 2.30±1.06, 3.57±1.09, and 2.21±1.99 in the non-fibrosis group, the fibrosis group, the significant fibrosis group and the cirrhosis group, respectively. The VTQ value and PGA index were positively correlated with the classification of liver fibrosis (VTG: r=0.719, PGA: r=0.683; both P<0.01).
CONCLUSION
The alcoholic liver fibrosis can be assessed by noninvasive VTQ technology and PGA index. As a real-time ultrasound elastography technique, VTQ is more accurate than the PGA index. Combination of the two methods is helpful for early diagnosis and treatment in the patients with alcoholic liver fibrosis.

Purpose:
This research was designed to investigate how miR-542-5p regulates the progression of hyperglycemia and hyperlipoidemia.
Materials and Methods:
An in vivo model with diabetic db/db mice and an in vitro model with forskolin/dexamethasone (FSK/DEX)-induced primary hepatocytes and HepG2 cells were employed in the study. Bioinformatics analysis was conducted to identify the expression of candidate miRNAs in the liver tissues of diabetic and control mice. H&E staining revealed liver morphology in diabetic and control mice. Pyruvate tolerance tests, insulin tolerance tests, and intraperitoneal glucose tolerance test were utilized to assess insulin resistance. ELISA was conducted to evaluate blood glucose and insulin levels. Red oil O staining showed lipid deposition in liver tissues. Luciferase reporter assay was used to depict binding between miR-542-5p and forkhead box O1 (FOXO1).
Results:
MiR-542-5p expression was under-expressed in the livers of db/db mice. Further in vitro experiments revealed that FSK/DEX, which mimics the effects of glucagon and glucocorticoids, induced cellular glucose production in HepG2 cells and in primaryhepatocytes cells. Notably, these changes were reversed by miR-542-5p. We found that transcription factor FOXO1 is a target of miR-542-5p. Further in vivo study indicated that miR-542-5p overexpression decreases FOXO1 expression, thereby reversing increases in blood glucose, blood lipids, and glucose-related enzymes in diabetic db/db mice. In contrast, anti-miR-542-5p exerted an adverse influence on blood glucose and blood lipid metabolism, and its stimulatory effects were significantly inhibited by sh-FOXO1 in normal control mice.
Conclusion
Collectively, our results indicated that miR-542-5p inhibits hyperglycemia and hyperlipoidemia by targeting FOXO1.

Objective To investigate the status quo of health literacy,motivation and self-management behaviours of patients with knee osteoarthritis(KOA),to explore the influence of health literacy and motivation on self-management behaviours to the patients with KOA,and to clarify the relationships among the three factors.Methods Convenience sampling method was used to select 169 KOA patients who were treated in 3 tertiary hospitals in Xianyang between September and December 2021.General status table,chronic disease health literacy scale,patient motivation scale and chronic disease self-management behaviour scale were employed in the on-the-spot survey.Pearson correlation was used to analyze the correlation of health literacy,motivation and self-management behaviour of patients with KOA.Results Total scores of health literacy,motivation and self-management behaviour of the patients with KOA were 79.66±11.91,54.97±9.95 and 23.75±8.89,respectively.It was found that health literacy and motivation of the patients were positively correlated with their self-management behaviour(r=0.872,r=0.822,both P<0.01).Health literacy of the patients was positively correlated with motivation of patients(r=0.877,P<0.01).Health literacy of the patients could be used to directly predict self-management behaviour of patients(β=0.708,95%CI:0.539-0.876),as well as to predict self-management behaviour of the patients through the mediating effect of patient motivation(β=0.228,95%CI:0.676-0.787).The mediating effect accounted for 24.36%of the total effect.Conclusions The health literacy,motivation and self-management behaviours of patients with KOA are all poor and they should be further improved.Patient motivation is the mediating variable in health literacy and self-management behaviour of the patients.It is suggested that nursing staff could encourage the motivation of patients hence to improve the self-management behaviour in the patients with KOA based on an improvement of health literacy.
