Objective To compare the efficacy of the emergency ESWL within 24 hours after the onset of renal colic and elective ESWL at 5 - 7 days after the onset of renal colic in the treatment for ureteral stones.Method From January 2008 to October 2009, 365 patients in the Second Hospital of Nanchang, with ureteral stones were admitted to our department for renal colic. They underwent emergency ESWL or elective ESWL with HK. ESWL- 108 energy electromagnetic shock wave lithotripter. Success rate of fragmentation, stone-free rate after 2 weeks of operation, pain recurrence rate, and complications were evaluated. The data were analyzed using SPSS 15.0. Results The success rate of fragmentation and the stone-free rate after 2 weeks of emergency ESWL were 96.76% and96.21%, respectively, which were higher than those (88.33% and 87.22%, respectively) of elective ESWL ( P ＜ 0. 05). The postoperative pain recurrence rate of emergency ESWL ( 4.32 % ) was lower than that (9.44%) of elective ESWL ( P ＜0.05). There was no difference of total complications between emergency ESWL (3.24%) and elective ESWL (2.78%) group (P ＞0.05). Conclusions Emergency ESWL is superior to selective ESWL and is the safe and effective method for the management of ureteral stones.

AIM: To investigate the effects of homocysteine (Hcy) on apoptosis and expression of caspases-3 in cultured human vascular smooth muscle cells (HVSMCs). METHODS: HVSMCs were cultured in vitro. The rate of apoptosis in HVSMCs was detected by flow cytometry. The expression of caspases-3 mRNA in HVSMCs was detected by reverse-transcription polymerase chain reaction (RT-PCR). RESULTS: The rates of apoptosis in HVSMCs incubated with 500 ?mol/L Hcy for 0 h, 6 h, 12 h, 24 h and 48 h were 2.39%?0.47%, 2.45%?0.64%, 7.58%?1.02%, 13.37%?4.71% and 17.69%?3.13%, respectively. The ratio of the absorbance of caspases-3 mRNA/GAPDH was 0.24?0.08, 0.29?0.10, 0.89?0.26, 1.37?0.24 and 1.82?0.53,respectively, suggesting that Hcy induces the apoptosis and expression of caspases-3 mRNA in HVSMCs in a time-dependent manner. The rates of apoptosis in HVSMCs incubated with 0, 100, 200, 500 or 1 000 ?mol/L Hcy for 24 h were 2.68%?0.23%, 2.79%?0.12%, 8.45%?2.41%, 13.37%?4.71% and 23.75%?5.56%, respectively, revealing that Hcy induced the apoptosis in HVSMCs in a concentration-dependent manner. CONCLUSION: Hcy induces the apoptosis in HVSMCs by regulating the expression of caspases-3, which may be one of the mechanisms involved in atherosclerotic effects of Hcy.

METHODThe extracts of BYHWD were obtained by water extraction and alcohol precipitation firstly, and then were dissolved with five solvents of different solubility parameter from 11.4 Cal(1/2) x cm(-3/2) to 23.40 Cal(1/2) x cm(-3/2) respectively. Their chromatographic fingerprints were determined by HPLC, finally the total quantum statistical moment parameters and its superposition properties were manual calculated and analyzed by their expressions.

RESULTAs a contrast as the whole prescription, the similarities of the various processed samples with butanol (11.4 Cal(1/2) x cm(-3/2)), methanol (13.5 Cal(1/2) x cm(-3/2)), 68% methanol (16. 67 Cal(1/2) x cm(-3/2)), 34% methanol (20.03 Cal(1/2) x cm(-3/2)) and distilled water (23.40 Cal(1/2) x cm(-3/2)) were 0. 074, 0. 973, 0. 934, 0. 991, 0. 993, respectively and while the RSD of these total quantum zero moment, center moment and variance of each chromatographic fingerprints for them were 63.04%, 16.22%, 69.38%, which showed significant difference in these chromatographic fingerprints. The total quantum statistical moment parameters of the superimposed chromatographic fingerprint with each sole samples were 3.203 x 10(5) mAu x s, 29.85 min, 389.97 min2, whereas the whole prescription's were 6.548 x 10(4) mAu x s, 29.44 min, 389.00 min2, that suggested that the absolute difference percentages between the superimposed and the whole were 2.209%, 1.389%, 0.2484%, respectively.

CONCLUSIONThe total quantum statistical moment of the chromatographic fingerprints is of characteristics with additive properties, it can be used in static and dynamic quality controlled analyses in the Chinese medicine multiple component systems.
