This study is to report the establishment of an UPLC-MS/MS method for the determination of plasma concentration of UA carried in self-microemulsifying drug delivery system (SMEDDS) and its pharmacokinetics in rats. It was used for determination and analysis when serum with internal standard was extracted from C18 solid-phase column. Acquity UPLC BEH C18 column (100 mm x 2.1 mm, 1.7 microm) was used for separation. The mobile phase was acetonitrile -0.1% ammonia with gradient elution at the flow rate of 0.2 mL x min(-1). The column temperature was 40 degrees C and the detection wave length was 210 nm. It was detected by negative ion using electrospray ionization source (ESI) and scanned by multiple reaction ion monitoring (MRM) mode. The liner relationship of UA was very good in the range of 1.19-3 815.00 ng x mL(-1) (r = 0.999 0). Recovery rate of different concentrations were 87.42%-89.95%. The precision of inter-day and intra-day were less than 11%. The method developed in our study was proved to be sensitive, rapid and simple. It is suitable for the pharmacokinetic study of UA-SMEDDS in rats.

Objective To evaluate the outcome of super-selective embolization of renal artery for severe hemorrhage after percutaneous nephrolithotomy (PCNL) and its effect on renal function. Methods From May 2008 to Feb 2010,severe bleeding occurred in 7 patients after PCNL in our hospital.(5 males and 2 females,average age of 54.9 years ).All cases were treated with super-selective renal angiography and 6 cases underwent microcoil embolization. Results Renal angiography showed pseudoaneurysm in 5 cases,pseudoaneurysm with arteriovenous fistula in 1 case and no severe bleeding in 1 case.Successful coil embolization was confirmed in 6 cases by angiography,and bleeding stopped within 3 -7 days after embolization.Serum creatinine and blood urea nitrogen were 59 -98 μmol/L(mean,78.3 μmol/L) and 1.86 -6.92 mmol/L( mean,4.8 mmol/L) 2 weeks after embolization,respectively. Conclusions Super-selective embolization of renal artery for severe hemorrhage after percutaneous nephrolithotomy has the advantages of remarkable hemostatic effects and mild impaired renal function,which is of the first choice.

·AIM:To present a case of late onset bilateral keratectasis after laser in situ keratomileusis (LASIK) for myopia with rigid gas-permeable contact lenses with a brief review of literature on this subject.·METHODS:A 27-year-old woman underwent bilateral uneventful LASIK for moderate myopia. Preoperative cycloplegic refractions were -5.50/-0.50×50° right eye (OD) and - 4.50/-1.00×15° left eye (OS).Corneal pachymetry was 526μm OD and 541μm OS, Preoperative corneal topography was normal and did not reveal any keratoconus or forme fruste keratoconus.Following the creation of flaps with 160μm plates,ablations of 102μm OD and 86μm OS were performed,estimated to leave residual stromal beds of 264μm OD and 295μm OS.·RESULTS:Twenty-nine months postoperatively,the patient developed bilateral inferior keratectasia of -12.50/-4.00×160° OD and -6.00/- 4.25×125° OS.Visual acuity was reduced in both eyes;the central cornea had steepened; and pachymetry showed central corneal thinning.Keratectasia was diagnosed,and rigid contact lenses were fitted.Three years later,the patient achieved satisfactory visual acuity and all-day lens wear with minimal complications.·CONCLUSION:Late keratectasia may follow LASIK for low to moderate myopia despite a thorough preoperative work-up.Rigid contact lenses can offer a safe,reversible option for improving visual acuity in such patients by delaying or avoiding the need for intracorneal ring segments implanting or penetrating keratoplasty.

Objective To evaluate application of recombinant human luteinizing hormone (r-hLH)used in ovarian stimulation of assisted reproductive technique and impact on outcome of pregnancy. Methods From Apr. To Jul. 2009, 123 patients with low LH level ( < 1 U/L) at day 3 of menstruation and downregulation of pituitary function undergoing in vitro fertilization-embryo transfer (IVF-ET) in Reproductive Medical Center, Provincial Hospital Affiliated to Shandong University were enrolled in this study, whom were classified into 66 cases treated by r-hLH in r-hLH group and 57 cases without r-hLH treatment in non-r-hLH group. In the mean time, 145 patients with normal level of serum LH ( 1-2 U/L) not given by r-hLH treatment and undergoing IVF-ET were matched as control group. Total amount of gonadotropin, estradiol levels and LH levels on the administration of human chorionic gonadotropin ( hCG), number of oocytes retrieved, number of 2PN zygotes, rate of high quality embryos, the rates of implantation and clinical pregnancy were compared among these three groups. Results The level of serum LH on the day of hCG administration were ( 1.59 ± 0.77 ) U/L in r-hLH group, (0.54 ± 0.25 ) U/L in non-r-hLH group and (2.39 ± 1.01 ) U/L in control group, which reached tatistical difference between every two groups (P < 0.05). The rates of high quality embryo were 59.36％ in r-hLH group, 57.79％ in non-r-hLH group,which were significantly lower than 65.94％ in control group, respectively (P < 0. 05 ). The rates of 2PN were 67.62％ in r-hLH group and 68. 32％ in control group, which were significantly higher than 62. 84％ in non-r-hLH group, respectively ( P < 0.05 ). The rates of implantation of 29.77％ in r-hLH group were significantly higher than 18.26％ in non-r-hLH group ( P < 0.05 ). The total amount of gonadotropin,estradiol level on the day of hCG administration, the number of oocytes retrieved, and clinical pregnancy rate were not significantly different among those three groups ( P > 0.05 ). Conclusion The administration of recombinant human uteinizing hormone in patients who are profoundly suppressed after down-regulation with long protocol can get more quality embryos, the higher rates of 2PN and implantation.

Objective To investigate protective activity against Aβ25-35-induced cytotoxicity in PC12 cells of different extracts and ursolic acid, which were isolated from pyrola decorata. Methods Aβ25-35-induced cytotoxicity in PC12 cells was established as the model in vitro. The cultured PC12 cells were divided into blank control group, DMSO control group, model control group, different extract groups of pyrola decorate and ursolic acid(UA) group. The different extract groups included ether extract (PE), acetidin extract (AE), n-butanol extract (BE), the water extract (WE), 50% ethanol extract (HEE). MTT assay was used to test the optimum concentration, and the number of viable cells in culture medium was measured by ELISA at 490 nm wavelength. Results The cell viabilities in different extracts groups(PE, AE, BE, WE, HEE) were respectively 89.3%, 77.2%, 79. 2%, 75. 1% ,74. 0% at the concentration of 5. 0 mg ? mL-1 . Moreover, ursolic acid showed the best neuroprotective activity (88.9%) at the concentration of 500 μg?L-1 . Compared with model control group, the survival rate of each group was remarkably increased, and the protective activities of PE and UA were more significant among them. Conclusion Different polar extracts of pyrola decorata and isolated ursolic acid have neuroprotective effects on Aβ25-35-induced cytotoxicity in PC12 cells in certain degrees.

Objective:To investigate the change of biological characteristics after stable knockdown of CKLF-like MARVEL transmembrane domain containing 3 (CMTM3)expression in PC3 by lentivirus shRNA and to reveal new therapeutic targets.Methods:The research includes two groups:sh393 is the experimental group in which CMTM3 is knocked down in PC3 cell line;shN is the control group in which CMTM3 is negatively knocked down.The expression of CMTM3 was detected by Western blot.The mi-gration ability of PC3 after stable knockdown was detected by Transwell and Wound healing assay.The invasion ability of PC3 was detected by Matrigel assay.Results were obtained from at least three indivi-dual experiments.Results:The expression of CMTM3 in sh393 group is significant lower than shN group (0.004 0 ±0.000 4 vs.0.490 0 ±0.055 7,P <0.001)detected by Western blot.It also had statistical significance in Matrigel assays (248.6 ±4.5 vs.113.0 ±3.3),Transwell (203.6 ±1.9 vs.103.0 ± 1.2)and Wound healing assays (95.0 ±2.9 vs.33.0 ±1.5)that knockdown of CMTM3 promoted mi-gration,and invasion of PC3 cells in vitro (P <0.001).Conclusion:Negative correlation exists between the stable knockdown of CMTM3 and change of biological characteristics in PC3 cells,and knocking down CMTM3 affects migration,and invasion ability in PC3 cells.
