Objective To observe the effects of soluble epoxide hydrolase inhibitor t-AUCB on foam cell formation and cholesterol efflux in macrophage.Methods Mouse macrophages RAW264.7 were cultured and stimulated with ox-LDL (80 μmol/L) in the absence (group A) or presence of t-AUCB (1,10,50,100 μmol/L,group B) or t-AUCB (100 μmol/L) pretreated with PPARγ antagonist GW9662 (5 μmol/L,group C).The foam cell was identified by oil red O staining.The cholesterol efflux rates of 3 Hcholesterol in cells were measured by liquid scintillation counter.mRNA and protein expressions of ABCA1 were detected by real-time PCR or Western blot,respectively.Results Oil red O staining showed that t-AUCB (100 μmol/L) significantly inhibited foam cell formation which could be significantly reversed by GW9662 (all P ＜ 0.05).t-AUCB dese-dependently increased cholesterol efflux rates in mouse macrophage [(5.91+0.18)％ in group A,(7.03 ±0.33)％,(8.05 ±0.32)％,( 9.04 ±0.14)％,(10.06±0.85)％ in 1,10,50,100 μmol/L t-AUCB groups,all P＜0.05 vs.group A],which could be reversed by pretreatment with GW9662 [ (6.33 ±0.15)％ in 100 μmol/L t-AUCB + GW9662 group].t-AUCB also upregulated ABCA1 mRNA and protein expressions in a dose-dependent manner which could be significantly attenuated by pretreatment with GW9662.Condusion t-AUCB could inhibit foam cell formation by improving cholesterol efflux through activating PPARγ-ABCA1 pathway in macrophage.

This is a case report of mediastinal fungal granuloma in an immunocompetent host. The definite diagnosis was made by pathological biopsy via video-assisted thoracoscopy and silver methenamine staining showed aspergillus hyphae and spores in the epithelioid granuloma. In conclusion, opportunistic pathogenic fungi can cause granulomatous inflammation in mediastinal lymph nodes in an immunocompetent host, as it can do in an immunocompromised host. More attention should be paid on tissue biopsy and pathological examination to ensure a correct diagnosis for these kinds of cases.

Objective To explore the effect of SA liposome mediated human interleukin-10 (IL-10) gent transfection on NHE-1 mRNA expression in penumbra area following focal cerebral ischemia reperfusion injury in rats. Methods Totally 78 male SD rats were randomly divided into normal control group (n=6), MCAO group (n=24), hIL-10 transfection group (n=24) and empty vector transfection group (n=24). Longa's method was employed to establish MCAO models in the latter 3 groups. The rats in the MCAO group underwent stereotactic operation without drug injection, and the hIL-10 transfection group and empty vector transfection group were injected stereotactieally with pcDNA3.1-IL-10 and pcDNA3.1, respectively, both by SA liposome mediation. After transfection, RT-PCR and ELISA were used to determine the effect of transfection, TTC staining was conducted to detect the infarct volume. Meanwhile, real-time quantitative PCR was performed to examine the expressions of NHE-1 mRNA and NF-κB mRNA in the penumbra area. Results (1) SA liposome effectively mediated the hIL-10 gene to transfect the brain tissue. Also hIL-10 gene transfection played neuroprotective effect by reducing the brain infarct volume. (2) The expression of NF-κB mRNA in different groups was 1.00±0.33, 4.76±0.41, 4.58±0.62 and 2.77±0.43, respectively, hIL-10 gene transfection also inhibited the increase of NF-κB mRNA expression in the penumbra area following the cerebral ischemia reperfusion injury. (3) The expression of NHE-1mRNA was 1.00±0.22, 4.16±0.48, 3.97±0.51 and 2.82±0.47, respectively, hIL-10 gene transfection also inhibited the increase of NHE-1 mRNA expression in the penumbra area following the cerebral ischemia reperfusion injury. Conclusions The hIL-10 transfection can exert the protective effect on the brain against cerebral ischemia-reperfusion injury partly via inhibiting the NHE-1 mRNA expression.

OBJECTIVETo investigate the sex chromosomes and the expression of insulin-like growth factor-II (IGF-II) on activated human unfertilized oocytes after intracytoplasmic sperm injection(ICSI) with calcium ionophore A23187 and puromycin.

METHODSAll 95 discarded oocyes that showed no evidence of fertilization at 16-18 h after in vitro maturation and intracytoplasmic sperm injection cycles (IVM-ICSI)/conventional ICSI were exposed to calcium ionophore A23187 (5 micromol/L) for 5 min and then were incubated with puromycin (10 microg/mL) for 4 h. After activation, the oocytes were cultured in vitro for 3-5 days. The sex chromosome analysis was performed by dual color fluorescence in situ hybridization. The expression of IGF-II on the activated embryos, normal embryos, and parthenotes was examined.

RESULTSThe combination of calcium ionophore A23187 with puromycin could activate the unfertilized oocytes 22 h after ICSI. The activated rate, cleavage rate, and quality of activated embryos of the IVM-ICSI group were similar to those of ICSI group, respectively. Sex chromosome analysis indicated that 8 male and 5 female embryos had been derived from two pronucleus and a second polar body. The expression of IGF-II on activated embryos and normal embryos was high and similar, which was much stronger than that of parthenotes.

CONCLUSIONThe combination of calcium ionophore A23187 with puromycin could effectively activate unfertilized oocytes 22 h after ICSI. Moreover, the unfertilized oocytes activated by calcium ionophore A23187 and puromycin had normal sex chromosomes and expression of IGF-II like the normal embryos. These suggest that oocyte activation may be considered as a remedial measure in the presence of total or nearly total fertilization failure in ICSI.

Objective To provide a practicable method for the complete display and localization of the posterolateral structures (PLS) of the normal knee through MRI study. Methods 30 tibial bone specimens were observed to establish the bony landmark for localizing the knee. In 50 cadaver knees, the angles between lateral tibial plateau and the long axis of the individual structure of PLS were measured. Then the scan methods of the oblique MR images were determined based on above results. The routine and oblique scans of T 1WI were performed in 40 normal knees. The display effect and appearance of the PLS were observed on MRI. Results The lateral tibial plateau was a stable bony landmark for measuring and localizing of the knee. In the 40 normal knees, The fibular collateral ligament could be intactly displayed on 70? posterior coronal oblique images in 34 cases (85%). The popliteus could be better seen on either 45? medial sagittal oblique in 34 cases (85%) or 60? posterior coronal oblique planes in 36 cases (90%). The popliteofibular ligament could be intactly appreciated on both 60? posterior coronal oblique in 32 cases (80%) and 70? lateral sagittal oblique images in 34 cases (85%). Although the arcuate ligament and the fabellofibular ligament could occasionally be seen on routine and oblique images, but the display rate was lower. Conclusion The oblique MR imaging can intactly display the main structures of PLS, and can be useful in diagnosing the injuries in those structures.
