Aerotitis media occurs frequently among flyers. 40 cases have been treated with electro- acupuncture in our hospital with satisfactory results. Xiaguan was selected as local point and Hegu as distal point. The patients were needled once a day or every other day. The total rate of effectiveness was 90.0%. According to Western medicine, this disease is due to poor pressure-equilibrating function of the Eustachian tube. The mechanism of treating this disease was explained by traditional Chinese medicine and western medicine theory.

OBJECTIVETo observe the effect of Hydroxy Safflower Yellow A (HSYA) on the expression of osteogenic markers, such as alkaline phosphatase, Cbf(alpha)l and type I collagen, and explore the mechanism of HSYA in the prevention and treatment of glucocorticoid-induced ischemic necrosis of femoral head.

METHODSFifteen healthy and adult New Zealand white rabbits were collected and weighted 0.9 to 1.3 kg. The rabbits were injected abdominally with anesthetic drugs, then received marrow cavity puncture of tibia and anterior superior iliac spine to get bone marrow blood. Rabbits bone marrow mesenchymal stem cells (BMSCs) were separated from the bone marrow blood, cultured in vitro and passaged. The 3rd generation of BMSCs which had good growth condition were randomly divided into blank group, model group and HSYA groups with different doses. The BMSCs in model group were treated with high dose of dexamethasone to induce adipogenic differentiation of cells cultured in vitro, and inhibit osteogenic differentiation. The BMSCs in HSYA groups received high dose of dexamethasone and different concentrations of HSYA simultaneously. The blank group received not any special handling. After a week,the expressions of alkaline phosphatase, Cbf(alpha)l and type I collagen mRNA were detected.

RESULTSThe alkaline phosphatase activity was significantly decreased in BMSCs of the model group as compared with the blank group (P < 0.01), and the expression of Cbf(alpha)l and type I collagen mRNA were also decreased significantly (P<0.01). The alkaline phosphatase activity was significantly increased in BMSCs of each HSYA group as compared with the model group (P < 0.05 or P < 0.01), and the expression of Cbf(alpha)l and type I collagen mRNA were also increased significantly (P < 0.05 or P < 0.01).

CONCLUSIONThe mechanism of HSYA may be related to the effect of antagonism to the reduced osteogenic differentiation induced by glucocorticoid.

OBJECTIVETo determine the levels of blood spot carnitine and acylcarnitine in children aged 0-15 years by tandem mass spectrometry, offer basic data for evaluating carnitine nutritional status and diagnosing metabolic diseases of organic acid and fatty acid.

METHODSThe concentration of carnitine and acylcarnitines were measured in blood spot by tandem mass spectrometry using underivatized samples. The samples included those from 1376 perinatal neonates, 49 neonates above 1 week of life, 64 children aged up to 1 year and 401 children aged 1 year to 15 years. A few premature infants and low birth weight infants were involved in perinatal neonates without selection. Other samples were taken from mainly outdoor patients for little surgical preoperative examination. Patients suffering from fever, diarrhea, liver disease, severe fat-metabolic diseases were excluded from this study.

RESULTSThe concentrations of carnitine (C(0)); short-chain acylcarnitines (SC-AC), including acetyl (C(2)), propionyl (C(3)), malonyl (C(3)DC), butyryl (C(4)), methylmalonyl (C(4)DC), isovaleryl (C(5)), glutaryl (C(5)DC); middle-chain acylcarnitines (MC-AC), including hexanoyl (C(6)), hexanediol (C(6)DC), octylenoyl (C(8:1)), octanoyl (C(8)), decadienoyl (C(10:2)), decanoyl (C(10:1)), decanoyl (C(10)); total carnitine and acylcarnitines (TCAC)were lower in neonate, highest in 1-3 months of age, higher in 6-12 months of age, and kept at the same level between 2 and 15 years of age. The concentrations of total long-chain acylcarnitines (LC-AC), including lauren (C(12:1)), lauroyl (C(12)), tetradecanoyl (C(14:1)), tetradecanoyl (C(14)), 3-hydroxy-tetradecanoyl (C(14)OH), hexadecenoyl (C(16:1)), hexadecanoyl (C(16)), 3-hydroxy-hexadecanoyl (C(16)OH), 3-hydroxy-hexadecanoyl (C(16:1)OH), octadecadienoyl (C(18:2)), octadecenoyl (C(18:1)), octadecanoyl (C(18)), 3-hydroxy-octadecenoyl (C(18:1)OH), and 3-hydroxy-octadecanoyl (C(18)OH) were the highest in neonate, decreased gradually, and kept the same level between 2 and 15 years of age. The concentrations of C(0) (23.387 ± 7.702) µmol/L, (30.064 ± 8.252) µmol/L, (25.021 ± 6.630) µmol/L, of LC-AC (4.998 ± 1.557) µmol/L, (2.854 ± 0.821) µmol/L, (2.459 ± 0.553) µmol/L, of TCAC (43.497 ± 12.632) µmol/L, (49.013 ± 12.497) µmol/L, (39.656 ± 9.257) µmol/L were significantly different among the groups of neonate, up to 1 year and above 1 year (P < 0.01). The concentrations of C(0) (24.115 ± 7.715) µmol/L and TCAC (43.65 ± 5.252) µmol/L in perinatal male neonates were higher than that (22.696 ± 7.246) µmol/L, TCAC (41.90 ± 5.038) µmol/L in female neonates. The C(0)/TCAC ratio of neonatal group (54.0% ± 7.1%) was significantly lower than that in the children group (62.1% ± 6.1%, P < 0.05), LC-AC/TCAC (33.5% ± 6.0%), MC-AC/TCAC (1.3% ± 0.3%), SC-AC/TCAC (11.6% ± 2.5%)ratios of neonatal group were higher than that of children group respectively (30.1% ± 4.9%; 0.9% ± 0.6%; 6.5% ± 2.3%, P < 0.05).

CONCLUSIONSConcentrations and profiles of carnitine and acylcarnitines change significantly during the first year of life, the age should be considered as a factor when evaluating carnitine nutritional status and diagnosing metabolic diseases of organic acid and fatty acid. Concentrations of carnitine and acylcarnitines were a little higher in male neonates than in female.

To determine whether Smac/DIABLO (second mitochondrial activator of caspases/direct inhibitor of apoptosis protein-binding protein of low isoelectric point [PI]) and XIAP (X-chromosome-linked inhibitor of apoptosis protein) serve to regulate neuronal apoptosis following seizures, we investigated seizure-induced changes in caspase-9, Smac/DIABLO and XIAP protein expression and the in vivo effect of caspase-9 inhibition. Animals received unilateral intra-amygdaloid injection of kainic acid (0.5 microg) to induce seizures for 1 h. The seizures were then terminated by diazepam (30 mg/kg). Animals were killed 0, 2, 4, 8, 24 or 72 h following diazepam administration. The apoptotic and surviving neurons in hippocampus were observed by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) and cresyl violet staining, the expression of Smac/DIABLO, XIAP and caspase-9 was detected with immunofluorescence and western blot. The results showed that the levels of XIAP and the 46-kDa proenzyme form of caspase-9 were unaffected by the seizures. The expression of Smac increased at 2 h and the 37-kD cleaved fragment of caspase-9 was detected at 4 h, TUNEL-positive neurons appeared at 8 h and reached maximal at 24 h following seizure cessation within the ipsilateral (the same side as the intra-amygdaloid injection of kainic acid) CA3 subfield of the hippocampus. Intracerebroventricular infusion of caspase-9 inhibitor z-LEHD-fluoromethyl ketone (z-LEHD-fmk) significantly decreased TUNEL-positive neurons and increased the number of surviving cells. Caspase-9 immunoreactivity increased and Smac/DIABLO, XIAP immunoreactivity became extensive within the ipsilateral CA3 neurons. TUNEL-positive neurons and the alterations of the expression of Smac/DIABLO and XIAP within the ipsilateral CA3 were not detected within the contralateral hippocampus. These results suggest that seizures lead the translocation of Smac/DIABLO into the cytosol, the activation of caspase-9 and the change of subcellular locoalization of XIAP. These changes may play a role in the brain damage induced by seizures. Caspase-9 is possibly a potential therapeutic target in the treatment of brain injury associated with seizures.

Background Posterior capsular opacification(PCO) is common complication after extrecapsular extract of cataract.Matrix metalloproteinases-3 (MMP-3) can degrade all the extracellular matrix except polyose.The gene therapy of PCO upon MMP-3 is the researching hot topic.Fibronectin ( FN ) is a degrade gelatin,so its expression can reflect the effect of MMP-3 on LECs indirectly. Objective The aim of this study was to construct MMP-3 eukaryotic recombination plasmid and transfect to lens epithelium cells(LECs) for the observation of MMP3 expression,and to explore the feasibility of gene therapy for after cataract. Methods Six fresh lenses were obtained from pigs.LECs were cultured using explant method.The eukaryotic expression vector pEGFP-N1-MMP-3 was reconstructed with MMP-3 and pEGFP-N1 plasmids.The accuracy of MMP-3 gene fragment was confirmed by double enzyme digestion and DNA sequencing analysis.After transfecting pEGFP-N1-MMP-3 into LECs of pig,the expression of MMP-3 protein in the cells was indirectly observed by green fluorescent protein.The expression of FN in LECs was detected using Western blot. Results The result of double enzyme digestion was consistent with the base number of pEGFP-N1 plasmids and target fragment.By enlacing the result of DNA sequencing analysis with software,the resemblance of the DNA sequence of MMP-3 from recombination plasmid pEGFP-N1-MMP-3 and that of homo MMP-3 was 99.6％,indicating that the target fragment was inserted to pEGFP-N1 plasmids successfully.Green fluorescence for GFP was seen in the LECs in pEGFP-N1-MMP-3 transfected group,but absent response for GFP was in empty vector group.Western blot revealed that the relative expression level of FN in LECs was 0.666±0.008 in pEGFP-N1-MMP-3 trasfected group and 0.326 ±0.071 in empty vector group,with a significant difference between these two groups(P=0.000). Conclusions Eukaryotic recombination plasmid pEGFP-N1-MMP-3 is successfully constructed,and MMP-3 can be expressed in LECs after transfected.These results lay a foundation for the further research of MMP-3 gene therapy for PCO.

OBJECTIVESTo investigate role of hypoxia inducible factor 1 (HIF-1) in the transcriptional activation of heat shock protein 70-2 (HSP70-2) in hepatocellular carcinoma (HCC) cells under hypoxic conditions.

METHODSHCC cells were exposed to reduced oxygen atmosphere (1% O2), or treated with YC-1 or HIF-1 alpha siRNA, the expression of HIF-1 alpha and HSP70-2 were detected by Western blot analysis. Serial deletions of the HSPA2 promoter were cloned in the reporter pGL3-Basic plasmid. These reporter plasmids were co-transfected with HIF-1 alpha siRNA, and the promoter activities were detected with the dual luciferase assay.

RESULTSWestern blot analysis showed that both HIF-1 alpha and HSP70-2 proteins were strongly increased after HCC cells were exposed to hypoxic conditions (1% O2) for 6 h, and the expression level of HSP70-2 was increased in a time-dependent manner. Treatment of HepG2 cells with YC-1 or HIF-1 alpha siRNA significantly inhibited the expression of HIF-1 alpha and HSP70-2. In silico analysis of the HSP70-2 promoter using the Gene2 Promoter software revealed the presence of two putative hypoxic response element (HRE) consensus at -446bp (HRE1) and -238bp (HRE2). Depletion of promoter sequence between -653 and -385 led to a dramatic reduction of promoter activity, whereas further deletion to position -201 did not reduce the activity further. These data suggested that HRE1 plays an important role in hypoxia-induced activation of the HSPA2 promoter. Site-directed mutagenesis further confirmed these results. Mutation of HRE1 but not of HRE2 abrogated the sensitivity of the HSP70-2 promoter to hypoxia.

CONCLUSIONSHSP70-2 expression is up-regulated in response to hypoxia and a HIF-1 binding site (HRE1) in the HSP70-2 promoter is involved in this response.
