The ^1 S0 nucleonic superfluids are investigated within the relativistic meanfield model and Bardeen-Cooper-Schrieffer theory in hyperonic neutron stars. The ^1 S0 pairing gaps of neutrons and protons are calculated based on the Reid soft-core interaction as the nucleon-nucleon interaction. In particular, we have studied the influence of degrees of freedom for hyperons on the ^1 S0 nucleonic pairing gap in neutron star matter. It is found that the appearance of hyperons has little impact on the baryonic density range and the size of the ^1S0 neutronic pairing gap; the ^1S0 protonic pairing gap also decreases slightly in this region where ρB = 0.0-0.393 fm^-3. However, if baryonic density becomes greater than 0.393 fm^-3, the ^1S0 protonic pairing gap obviously increases. In addition, the possible range for a protonic superfluid is obviously enlarged due to the presence of hyperons. In our results, the hyperons change the 1 So protonic pairing gap, which must change the cooling properties of neutron stars.

AIM: To evaluate the role of the 13C-methacetin breath test(13C-MBT) in the assessment of acute liver injury in a rat ***: Acute liver injury in rats was induced by a single intraperitoneal injection of D-galactosamine(D-GalN). Forty-eight male Sprague-Dawley rats were randomly assigned to a control group(n = 8) and five model groups(each n = 8), and acute liver injury was assessed at different time points(6, 12, 24, 48 and 72 h) after D-GalN injection. The 13C-MBT, biochemical tests, 15-min retention rate of indocyanine green(ICGR15), and liver biopsy were performed and compared between the control and model groups. Correlations between parameters of the 13C-MBT(Tmax, MVmax, CUM120 and DOBmax), biochemical tests, ICGR15 and liver necrosis score were also analyzed using Spearman'scorrelation ***: Tmax, MVmax, CUM120 and DOBmax, as well as most of the traditional methods, correlated with the liver necrosis score(r = 0.493, P < 0.05; r =-0.731, P < 0.01; r =-0.618, P < 0.01; r =-0.592, P < 0.01, respectively). MVmax, CUM120 and DOBmax rapidly decreased and were lower than those in the controls as early as 6 h after D-GalN injection(3.84 ± 0.84 vs 5.06 ± 0.78, P < 0.01; 3.35 ± 0.72 vs 4.21 ± 1.44, P < 0.05; 52.3 ± 20.58 vs 75.1 ± 9.57, P < 0.05, respectively) and reached the lowest point 24 h after D-GalN injection. MVmax, CUM120 and DOBmax returned to normal levels 72 h after D-GalN injection and preceded most of the traditional methods, including liver ***: The 13C-MBT is a sensitive tool for the timely detection of acute liver injury and early prediction of recovery in a rat model. Further clinical studies are warranted to validate its role in patients with acute liver injury.

AIM: To investigate the effects of Msx2 on lens epithelium cell cycle, and evaluate the changes of the proliferation, apoptosis of lens epithelium cells. METHODS: Mice lens epithelium cells were cultured and transfected with pEGFP-Msx2 and control. Msx2-deficient mice (Msx2(-/-)) lens tissue were isolated. Lens tissue and transfected cells were prepared for mRNA extraction using Trizol reagent. CyclinD1 and Prox1 expression were evaluated by real-time RT-PCR. BrdU incorporation and apoptosis rate were investigated by immunofluorescence and flow cytometry analysis. RESULTS: After transfected with pEGFP-Msx2, lens epithelium cells failed to incorporate BrdU and anti - phospho-histone-3 immunofluorescence failed to detect cell nuclei which GFP were positive. Msx2 over expression resulted in increasing apoptosis rate in lens epithelium cells. CyclinD1 and Prox1 expression increased significantly in Msx2 knockout mice by real time RT-PCR quantization and CyclinD1 expression decreased significantly in Msx2overexpressed cell. CONCLUSION: Msx2 has the effect of inhibiting proliferation and differentiation, triggering apoptosis on mice lens epithelium cells.
