Objective:To observe the effect of different concentration of Qianggubao decoction extract on proliferation of osteoblastic cells cultured by high glucose in vitro. Methods: osteoblastic cells was isolated from the skull of 1-2 day newly born SD rats by means of Trypsin-collagenase digestion and identified by image analysis,V-G collagen staining,ALP staining, calcification nod staining etc. Different concentrations of Qianggubao decoction extract were added to the osteoblastic cells cultured by high glucose in vitro(final concentration:300mg/dl)and incubuted.The effects of Qianggubao decoction extract on the proliferation of osteoblasts was monitored by MTT analysis. Results:Qianggubao extract of 100, 50, 10?g/ml all promoted for osteoblastic cell proliferation, the 100?g/ml and 50?g/ml had the better effects (P

Objective To investigate the clinical value of different double-J tube indwelling time in the treatment of ureteral stone-street complications after flexible ureteroscope lithotripsy. Methods Clinical data of 64 kidney calculi patients with ureteral stone-street complications after flexible ureteroscope holmium laser lithotripsy were retrospectively analyzed. The patients were divided into observation group (extubating the double-J tube 2 weeks after the surgery) and control group (retaining the double-J tube) with 32 cases in each group. The calculi clearance results and complication were compared between 2 groups. Results The success rate of stone removal in observation group was significantly higher than that in control group: 100.0% (32/32) vs. 65.6%(21/32), the calculi elimination time was significantly shorter than that in control group:(26.4 ± 6.6) d vs. (45.3 ± 10.9) d, the treatment cost was significantly lower than that in control group:(768.4 ± 152.6) yuan vs. (1 262.3 ± 156.8) yuan, the incidences of irritation symptoms of bladder and macroscopic hematuria were significantly lower than those in control group: 15.6% (5/32) vs. 90.6%(29/32) and 15.6% (5/32) vs. 100.0% (32/32), and there were statistical differences (P<0.05). There was no statistical difference in incidence of renal colic between 2 groups (P>0.05). Conclusions Removing the double-J tube 2 weeks after flexible ureteroscope lithotripsy results in higher stone clearance rate and less complications compared with retaining the double-J tube. It can reduce the occurrence of irritation symptoms of bladder, macroscopic hematuria and treatment cost.

Objective To investigate the proportion, risk factors and tendency of the change of stones composition in recurrent urolithiasis. Methods One hundred and fifty-six recurrent urolithiasis patients from January 2011 to January 2016 were enrolled. Compositions of initial and recurrent stones were measured by infrared spectrophotometry. Stones types, recurrence interval and recurrence frequency were studied as potential risk factors for composition change. Chi square test and Logistic regression analysis was employed in the statistical analysis. Results Stones composition changed during recurrence in 48 patients (30.8%). 22.8%(18/79) of calcium oxalate stones change to infection stones, and 25.8%(8/31) of infection stones changed to calcium oxalate. Univariate analysis showed the risk ratio of composition change in the patients with recurrence interval of 1- 5 years was 0.529(P = 0.039) , compared with those of less than 1 year or more than 5 years. Logistic regression analysis showed the odds ratio of recurrence interval of 1- 5 years was 0.242 (95%CI: 0.086- 0.718, P = 0.012). Conclusions Stones composition changes in about 30.8% of recurrent urolithiasis. The mutual conversion between calcium oxalate and infection stones is the most common. Recurrence interval is an independent risk factor to predict composition change.
