To observe the high glucose concentration on proliferation and fibronectin (FN) synthesis of glomerular mesangial cells (GMC),a culture of human GMC was established and the cell proliferation was assessed using MTT method and cell counting, and the changes in FN was analyzed with RT PCR and ELISA. It was found that high glucose concentration inhibited GMC proliferation and increased FN synthesis in dose and time dependent manner.The results suggest that hyperglycemia may have important role in the development of diabetic nephropathy.

Objective To observe the clinical short-and long-term curative effect of the surgical treatment of female stress urinary incontinence (SUI) with tension-free vaginal tape-obturator (TVT-O) treatment,and discuss the safety of the operation and postoperative quality of life.Methods The data were collected from 130 patients with SUI who were underwent TVT-O treatment.The patients'perioperative period,follow-up of postoperative complications,and comparison of the quality of life before and after surgery were analyzed retrospectively.Results A total of 130 patients was successfully completed their surgeries with a mean operative time (47.01 ± 18.82)min,average blood loss (64.38 ±99.62)ml,mean catheterization (2.67 ±0.90)d,and the average length of stay (4.73 ±2.14)d.A total of 101 cases was completed the postoperative follow-up with (a) preoperative quality of life in patients with ⅡQ-7 score 6 to 21 points and an average of (15.74 ± 3.87) min,(b) symptoms of lower urinary tract UDI-6 score of 3 to 22 minutes and the average (10.51 ± 3.70) min,(c) postoperative quality of life improved significantly ⅡQ-7 score from 0 to 21 points and an average of (1.59 ±4.37)points,and (e) UDI-6 score 0 to 14 points and an average of (1.63 ± 2.66)points.A total of 73 patients (72.3%) had the postoperative urinary incontinence,which subjective symptom were completely cured,significant improvement was 11 cases (10.9%),ineffectiveness was 6 cases (5.9%),pad using was 13 patients (12.9%),vaginal mesh exposure and erosion was 2 patients(2.0%),the sexual life postoperatively was affected in 8 patients (7.9%).Conclusions TVT-O treatment of SUI is not only easy to operate but also has clinically high security,few complications,low recurrence rate,and significantly improved patients' living quantities.However,patch compli cations can not be ignored and need further discussion.

Objective To evaluate the efficacy and safety of continuous infiltration of Lidocaine in joint replacement surgery.Methods From May 2013 to October 2013,patients scheduled to undergo total hip or total knee arthroplasty were randomized into two groups:the local infiltration analgesia group received continuous infiltration of Lidocaine while the other group received PCIA filled with fentanyl after surgery.The equipments were removed 48 hours after the surgery.The visual analogue scale score at five points (immediate postoperative,24 hours after the surgery while resting,24 hours after the surgery while exercising,48 hours after the surgery while resting,48 hours after the surgery while exercising) were recorded and if the score was higher than 4,analgesics wound be given to the patients.The vital sign,blood test,ECG,the circumference of lower limbs,the range of motion of the joint,the rehabilitation and complications were also recorded.Results 42 patients were included,11 male and 31 female.There were 25 patients and 36 total knee arthroplasties.17 patients underwent a total of 19 hip arthroplasties.The demographic data,the diagnosis and the surgery type were comparable between two groups.The VAS scores at immediate postoperative,24 hours and 48 hours after the surgery while resting,the average dose of analgesics and the complication rate were statistically different be tween two groups.However,the VAS scores at 24 hours after the surgery and 48 hours after the surgery while exercising,the change of the circumferences of the lower limb,the range of motion of the joint,the rehabilitation satisfactory rate and length of stay were comparable between two groups,while no significant difference was observed.One patient in the PCIA group suffered from incision fat liquefaction and healed after three weeks.There were no infection and subcutaneous hydrocele in both groups.Conclusion Continuous infiltration of Lidocaine is more effective than the PCIA while resting after joint replacement surgery and no inferior to it while exercising.It can decrease the amount of Opioid.

Objective To evaluate the difference in isokinetic strength of the knee muscles between knee osteoarthritis (KOA) patients aged 80 years and over and matched healthy controls,and to establish the association of isokinetic strength with pain and functional status in patients with KOA.Methods The study enrolled 32 patients aged 80 and over diagnosed with unilateral knee OA and 10 matched controls.Pain was evaluated by the visual analogue scale (VAS),the pain intensity scale and the Lequesne index for patients with knee OA.Functional status was assessed by the Timed Up and Go Test (TUGT),the Five Times Sit to Stand Test (FTSST) and the Timed 10 Meter Walk Test (TWT).Muscle strength was measured using the isokinetic dynamometer Biodex System 4 Pro.Bilateral isokinetic (concentric) knee flexion and extension with the protocol of 60 degrees/sec,180 degrees/sec was also performed.Results The difference in two angular velocities of extensor and flexor peak torques between the knee OA group and the control group was statistically significant (t=2.747,P< 0.05).The extensor peak torque was negatively correlated with age,Liquesce index scores,FTSST,TUGT and TWT (r=-0.39~~-0.75,P<0.05),but had no correlation with the VAS score or the Lequesne index pain score (r=-0.23~ 0.31,P>0.05).The regression analysis results suggested that the extensor peak torque and the VAS score together were important predictors for the Liquesce index (adjusted R2 =0.41).Conclusions The degree of knee muscle damage is closely related to the functional performance of the muscles in knee OA patients aged 80 years or over.The strength of the quadriceps and the intensity of pain are important predictors of disability for those patients.

Objective To determine the test-retest reliability of functional squat system (FSS) isometric muscle strength tests for patients with knee osteoarthritis. Methods The isometric muscle strength of thirty patientswith knee osteoarthritis (21 males and 9 females; age 45 to 89 years, mean age 68.73 ± 12.19 years) was tested twice within 1 week by the same tester. Three test results were obtained: maximum isometric extension strength, the time to initiate isometric extension and the average isometric extension strength. Intra-class correlation coefficients (ICCs) for the three tests were computed to evaluate their retest reliability. Results The ICCs of the maximum isometric extension strength and average isometric extension strength of the uninvolved and involved extremities were respectively 0.87, 0.88, 0.92 and 0.89. The ICCs of the initiation time for the uninvolved and involved legs were respectively 0.25 and 0.41. Conclusion In these tests of patients with knee osteoarthritis using the functional squat system, both the maximum isometric extension strength and the average isometric extension strength had very good test-retest reliability. These two test results could be used as reliable guidance for treatment and rehabilitation of osteoarthritic knees.
