OBJECTIVE:
To develop a five fluorescence-labeled multiplex amplification system for 15 loci and study genetic polymorphism in Xinjiang Uygur population.
METHODS:
The STR loci were screened. The alleles were named according to the number of repeats by sequencing. The sensitivity, species specificity, identity and stability of the five fluorescence-labeled multiplex amplification system for the 15 loci were all tested. Then, the genetic polymorphism was analyzed in Xinjiang Uygur population and compared with other ethnic groups including Xizang Tibetan, Xiuyan Manchu, and Guangzhou Han population.
RESULTS:
The 15 loci multiplex amplification system was established. The sensitivity was 0.3 ng with good species specificity, identity and stability. The distributions of genotype for 13 STR loci in Uygur population were in accordance with Hardy-Weinberg equilibrium with no genetic linkage between these loci. Most loci showed statistically significant among different populations.
CONCLUSION
The established system has application value in forensic evidence. The 13 STR loci in Uygur population have

OBJECTIVETo evaluate the clinical efficiency of selective cyclo-oxygenase-2 (COX-2) inhibitor compared to traditional nonselective NSAIDs for the prevention of heterotopic ossification (HO) after total hip arthroplasty (THA).
METHODSBy searching Medline, Embase, CENTRAL (Cochrane Central Register of Controlled Trials) and Science Citation Index et al, only randomised controlled studies of selective COX-2 inhibitors VS nonselective COX-1 and COX-2 inhibitors for the prevention of HO after THA were included. The quality assessment of included studies was evaluated according to the standard of the Cochrane Collaboration, and the data were analysised by statistic software Stata 10.0. The HO incidence of both groups in different degrees was compared.
RESULTSFour eligible randomised controlled trials of totally 808 patients were included. Meta-analysis results showed that no statistically significant difference was found in overall incidence of HO (RR = 1.08, 95% CI: 0.71-1.64,P = 0.73), incidence of moderate severe HO (Brooker II and III) (RR = 0.83, 95% CI: 0.48-1.42, P = 0.49) and any grade of Brooker classification between two groups. In all included studies, 16 patients receiving nonselective COX inhibitor (4.4%) discontinued treatment because of gastrointestinal toxicity,whereas 10 patients in the selective COX-2 inhibitor group (2.7%) discontinued for gastrointestinal side effects.
CONCLUSIONThe selective COX-2 inhibitors are as equally effective as nonselective NSAIDs for the prevention of HO after THA. Considering the side effects of nonselective NSAIDs, selective COX-2 inhibitors were recommend for the prevention of HO after THA.

AIM: To evaluate the effect of binocular visual function training in pediatric ocular trauma. METHODS: There were 76 patients (76 eyes) that were hospitalized with a primary diagnosis of ocular injury at the Affiliated Hospital of Medical College, Qingdao University between January 2006 and December 2009. Binocular visual function training was given after primary wound repair. Far stereopsis function were checked using AIT-1000 synoptophore fusion, and near stereopsis function was checked using Titmus stereogram.Binocular visual function was compared before and after training. RESULTS: Before binocular visual function training,26 eyes(34%)had no binocular vision, after training there were only 16 eyes(21%) without binocular vision. Before undertaking binocular visual function training with fusion, only 27 eyes (36%) had binocular vision, after the training there were 48 eyes (63%) with binocular vision. Before undertaking binocular visual function training with far stereopsis ,there were 23 eyes (30%) with binocular vision, after the training there were 29 eyes (38%). Before binocular visual function training with near stereopsis, there were 14 eyes (18%) with binocular vision, after the training there were 33 eyes (43%) with binocular vision. There was a significant difference in the number of patients with binocular vision before and after binocular visual function training. CONCLUSION:The training is useful for the reconstruction of binocular visual function in pediatric ocular trauma.

AIMTo study the effects of rhBNP on the cardiac hemodynamics and renal function in dogs with heart failure.
METHODSCongestive heart failure in dogs was induced by either rapid ventricular pacing (RVP), 250 beats.min-1 for 7-14 days or by thoracic inferior vena cava constriction (TIVCC) to 1/2 its original diameter. When remarkable hemodynamic changes appeared rhBNP was infused intravenously at the dosage of 10, 30 and 100 ng.kg-1.min-1, each dose lasting 30 min.
RESULTSIn dogs (n = 7) with RVP heart failure, intravenous infusion of rhBNP at 10-100 ng.kg-1.min-1, caused decreases in mean arterial pressure (MAP), left ventricular systolic pressure (LVSP), LVdP/dtmax, pulmonary arterial pressure (PAP), left ventricular end diastolic pressure (LVEDP), total peripheral vascular resistance (TPR) and renal vascular resistance (RVR) dose-dependently, without significant changes in cardiac output (CO), LVdp/dt/P, left ventricular work (LVW), renal blood flow (RBF) and heart rate (HR). This suggested that rhBNP reduced the pre-load and after-load of the dogs with congestive heart failure but showed no distinct effect on the contractility of the heart. In dogs (n = 7) with TIVCC heart failure, there were remarkable decreases in MAP and LVEDP following the rhBNP infusion, without further reduction of CO, but no marked change in HR, LVSP, LVdP/dtmax, RAP and TPR. In both animal models of heart failure, there were significant increases in urine volume and sodium excretion which were more significant in TIVCC dogs than in RVP dogs.
CONCLUSIONrhBNP reduced the pre-load and after-load in dogs with heart failure and showed remarkable diuretic effect, but did not affect the contractility of the heart.

OBJECTIVETo establish a murine model of sensitization, and investigate the effect and mechanism of sensitization on allogeneic donor bone marrow cells (BMCs).
METHODSSensitized BALB/c mice were established by transfusions of allogeneic splenocytes. The donor reactive antibodies were detected by binding and complement-dependent cytotoxicity assays. After irradiation, 1 × 10(7) BMCs of C57BL/6 donor mice were injected into non-sensitized or sensitized BALB/c recipient mice. The distribution pattern of donor BMCs in peripheral blood, spleen and bone marrow of recipient mice were analyzed at different time points (2 h, 12 h and 48 h) post transplantation. Hematopoietic recovery post transplantation was assessed, and survival was monitored. Moreover, sera and splenocytes derived from non-sensitized or sensitized recipients were incubated with allogeneic BMCs in vitro, and the cytotoxic indexes were calculated in the immune experiments.
RESULTSThe binding and complement-dependent cytotoxicity assays showed that a high level of donor reactive antibodies was presented in sensitized sera. Compared with the non-sensitized recipients, the homing assay showed significantly decreased distributions of allogeneic donor BMCs in peripheral blood, spleen and femur of sensitized recipients. Non-sensitized recipients survived long term after irradiation, while all the sensitized recipients died within 12-15 days. Fourteen days post transplantation, the white blood cells and BMCs of non-sensitized recipients were (3240 ± 300) × 10(6)/L and (396 ± 27) × 10(6)/femur, respectively; while the white blood cells and BMCs of sensitized recipients were (320 ± 80) × 10(6)/L and (6 ± 2) × 10(6)/femur, respectively; the differences were statistically significant between this two groups (P < 0.05). Seven days post transplantation, the percentage of donor cells in bone marrow of non-sensitized and sensitized recipients was (48.07 ± 4.70)% and (0.77 ± 0.11)%, respectively, and the differences were statistically significant (P < 0.05). Furthermore, the white blood cells and BMCs following transplantation decreased along with time in sensitized recipients. The immune experiments of complement-dependent cytotoxicity reaction, cytotoxic T lymphocytes reaction and antibody-dependent cellular cytotoxicity showed the cytotoxic indexes were higher in sensitized group than the non-sensitized group.
CONCLUSIONA sensitized model was established by transfusions of allogeneic spleen cells. Allogeneic donor BMCs were rejected in sensitized recipients, and its mechanism might be through immune impairment pathways.

To investigate the inhibition of cyclosporin A (CsA) on neutrophil adhesion to human umbilical vein endothelial cells (HUVECs, ECV-304) induced by hypoxia/reoxygenation and further explore its mechanism, a 1 h hypoxia/4 h reoxygenation model was reproduced using ECV-304. The adhesion rate of neutrophils to ECV-304 was determined by measuring the activity of endogenous hexosaminidase. The expression of endothelial cell adhesion molecules of E-selectin and ICAM-1 was measured by flow cytometry. The expression of cyclophilin A (CyPA) and the activation of ERK1/2 was compared among experimental groups by Western blot. The content of reactive oxygen species (ROS) was measured by Fenton reaction. After being stimulated with 1 h hypoxia/4 h reoxygenation, ECV-304 showed an enhanced neutrophil adhensiveness in association with an increased surface expression of E-selectin and ICAM-1. In parallel, the content of ROS was also increased. These effects were significantly suppressed by the addition of CsA. Most importantly, the expression of CyPA was significantly increased following 1 h hypoxia/4 h reoxygenation, which was accompanied with an increased activation of ERK1/2. Treatment with CyPA inhibitor CsA and CyPA antisense oligonucleotides significantly inhibited the activation of ERK1/2 and decreased the adhesion of neutrophils to ECV-304. The specific ERK1/2 inhibitor PD98059 caused an inhibition of neutrophil adhesion to hypoxia/reoxygenation-stimulated ECV-304. Our data confirm that CsA inhibits neutrophil adhesion to hypoxia/reoxygenation stimulated ECV-304 by a mechanism involving inhibition of the signal transduction of ROS, CyPA and ERK1/2.
