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.

To knock out β-lactoglobulin (BLG) gene and insert human lactoferrin (hLF) coding sequence at BLG locus of goat, the transcription activator-like effector nucleases (TALEN) mediated recombination was used to edit the BLG gene of goat fetal fibroblast, then as donor cells for somatic cell nuclear transfer. We designed a pair of specific plasmid TALEN-3-L/R for goat BLG exon III recognition sites, and BLC14-TK vector containing a negative selection gene HSV-TK, was used for the knock in of hLF gene. TALENs plasmids were transfected into the goat fetal fibroblast cells, and the cells were screened three days by 2 μg/mL puromycin. DNA cleavage activities of cells were verified by PCR amplification and DNA production sequencing. Then, targeting vector BLC14-TK and plasmids TALEN-3-L/R were co-transfected into goat fetal fibroblasts, both 700 μg/mL G418 and 2 μg/mL GCV were simultaneously used to screen G418-resistant cells. Detections of integration and recombination were implemented to obtain cells with hLF gene site-specific integration. We chose targeting cells as donor cells for somatic cell nuclear transfer. The mutagenicity of TALEN-3-L/R was between 25% and 30%. A total of 335 reconstructed embryos with 6 BLG-/hLF+ targeting cell lines were transferred into 16 recipient goats. There were 9 pregnancies confirmed by ultrasound on day 30 to 35 (pregnancy rate of 39.1%), and one of 50-day-old fetus with BLG-/hLF+ was achieved. These results provide the basis for hLF gene knock-in at BLG locus of goat and cultivating transgenic goat of low allergens and rich hLF in the milk.

The definition of critical quality attributes of Chinese materia medica ( CMM) was put forward based on the top-level design concept. Nowadays, coupled with the development of rapid analytical science, rapid assessment of critical quality attributes of CMM was firstly carried out, which was the secondary discipline branch of CMM. Taking near infrared (NIR) spectroscopy as an example, which is a rapid analytical technology in pharmaceutical process over the past decade, systematic review is the chemometric parameters in NIR model evaluation. According to the characteristics of complexity of CMM and trace components analysis, a multi-source information fusion strategy of NIR model was developed for assessment of critical quality attributes of CMM. The strategy has provided guideline for NIR reliable analysis in critical quality attributes of CMM.

OBJECTIVETo evaluate therapeutic effects of Rigidfix cross pins combined with Intrafix pins for the reconstruction of anterior or posterior cruciate ligament under arthroscopy.
METHODSFrom January 2009 to June 2010,34 patients with anterior or posterior cruciate ligament injuries were divided into two groups : group A and group B. There were 24 patients in group A, including 19 males and 5 females,with an average age of (31.83±9.57) years old. The patients in group A were treated with anterior cruciate ligament reconstruction under arthroscopy; Rigidfix cross pins and Intrafix pins were used to fix femoral and tibial side respectively. Among the 10 patients in group B, 8 patients were male and 2 patients were female, with an average age of (27.20+7.59) years old. The patients in group B were treated with posterior cruciate ligament reconstruction under arthroscope; Intrafix pins and Rigidifix cross pins were used to fix femoral and tibial side sepectively. The drawer test and Lachaman test were used to evaluate postoperative knee stability. All the patients were followed up at least 18 months. Lysholm and Tegner knee scores were used to evaluate the clinical therapeutic effects.
RESULTSAll the 34 patients were followed up, and the duration ranged from 18 to 26 months,with an average of (20.79±2.39) months. All the patients obtained good pain relief and knee stability. In group A,Lysholm scores significantly increased from 43.04±7.57 preoperatively to 85.41±4.68, 92.50±3.05, and 93.45±2.57 at 6,12, and 18 months postoperatively; Tegner scores significantly increased from 2.62±0.92 preoperatively to 7.45±1.14, 8.58±0.77, and 8.95±0.55 at 6, 12, and 18 months postoperatively. In group B,Lysholm scores significantly increased from 46.20±8.27 preoperatively to 86.40±5.14,90.40±2.67,and 92.00±3.85 at 6,12,and 18 months postoperatively ;Tegner scores significantly increased from 2.00±0.66 preoperatively to 7.10±0.99, 8.60±0.84, and 8.80±0.42 at 6,12, and 18 months postoperatively. There were no differences in Lysholm and Tegner scores between group A and B at different times during follow-up. Lysholm scores of all patients significantly increased from 43.97±7.79 preoperatively to 85.70±4.76,91.88±3.06,and 93.02±3.01 at 6,12,and 18 months postoperatively. Tegner scores of all patients significantly increased from 2.44±0.89 preoperatively to 7.35±1.09, 8.58±0.78, and 8.91±0.51 at 6,12,and 18 months postoperatively. During the follow-up period,there were no serious immunological rejection and complications.

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.
