To explore the potential of the anti-sense nucleic acid of CyclinD1 in lung cancer therapy, the expression vector containing the anti-sense nucleic acid of CyclinD1 was constructed and named pcDNA3.1-CyclinD1. The A549 cells were transfected with pcDNA3.1-CyclinD1 vectors. After being screened by G418, the stable expression positive clones were obtained. MTT method and flow cytometry technique were used to detect cell proliferation and apoptosis, respectively. The results showed the transfected cells exhibited significantly increased apoptosis and inhibited cell growth, compared with negative control and empty vector groups. To investigate the mechanism for anti-sense nucleic acid of CyclinD1 inducing A549 cells apoptosis, the expression levels of retinoblastoma protein (pRb), adenovirus E2 factor-1 (E2F-1), vascular endothelial growth factor (VEGF), matrix metalloproteinase (MMP)-2 and MMP-9 were detected by Western blot, and the results showed the expressions of these proteins were all decreased significantly in anti-sense nucleic acid of CyclinD transfected group, compared with those in negative control and empty vector groups. In a word, anti-sense nucleic acid of CyclinD1 induces the apoptosis of lung adenocarcinoma cancer cells, and the depressions of pRb, E2F-1, VEGF, MMP-2 and MMP-9 expressions may be the possible mechanism.

OBJECTIVETo observe the influence of H102 on the expression of amyloid protein and amyloid precursor protein in the hippocampus of APP695 transgenic mice.

METHODSThe 9-month-old APP695 transgenic mice were randomly divided into the model group and the H102 group; C57BL/6J mice were adopted as normal control group. The H102 group were injected with H102 in a dose of 3 microl/per mouse in lateral ventricle, once a day, for ten days; while the model group and the control group were injected with saline. The hippocampus and temporal cortex of the brain sections from transgenic mice and wild type female mice were subjected to immunohistochemistry and Congo red histological staining, and observed the difference of the protein expression under microscope. The expression of the APP protein was detected by Western blot.

RESULTSAbeta and APP immunohistochemistry showed density of positive cell in the CA1 region of hippocampus of control group were less than model group. H102 peptide reduced the area, and density of positive cells. Congo red staining showed there were lots of amyloid plagues in the brains of model mice but not in the brains of normal control. And the Western blot showed the content of the APP protein of the model group was much higher than the H102 group. H102 significantly decreased the amyloid plagues.

CONCLUSIONThe expression of APP, Abeta are increased in APP695 transgenic mice, and H102 can decrease the level of APP, Abeta in transgenic mice.

Objective To investigate the distribution status of coal-burning fluorosis (endemic fluorosis) areas in Luoyang and to provide scientifc evidence for making strategies in prevention and control. Methods In 2006, a household per village was chosen to carry the general survey so as of disease condition, living habits and housing structure among 941 coal-burning pollution fluorine sickness natural villages in Yanshi, Mengjin, Xin'an, Luanchuan counties and Geely area which were under the jurisdiction of Luoyang. In the general survey, the sampled village having a population of more than 500 person was considered as a major survey village, and water fluoride, 8 - 12 year-old child fluorine spot on tooth and the urinary fluoride were surveyed. Water fluoride and the child urinary fluoride determination used the fluoride ion selective electrode method, and the children's dental fluorosis used Dean method. Results The endemic fluorosis of Luoyang existed 742 in endemic fluomsis villages, compared with history, a decrease of 199 in number. Ninety-six point seven per cent( 142 543/147 419) of the households were consuming smoke-free coal. Households using intact kitchens accounted for 93.6%( 137 919/147 419). Of which 63.0%(86 889/137 919) of kitchens were mixed up with bedrooms. Total 125 060 people were using coal- fired furnace for heating, of which 87.8%(109 802/125 060) had smoke-free facilities, 12.2%(15 258/125 060) had none. Among 52 endemic villages with population of more than 500 people surveyed, a total of 183 water samples were collected, 2 had water fluoride exceeding 1.0 rag/L, the highest water fluoride being 1.04 rag/L, averaging 0.39 mg/L Sixteen villages had a prevalence rate of dental fluorosis for children less than 30.00%, accounting for 30.8% (16/52), 36 endemic villages the prevalence of dental fluorosis detection rate of more than 30.00%, accounting for 69.2%(36/52). Twenty-thrce villages had a dental fluorosis index greater than 0.6, severe dental fluorosis was not found. Real-time measurement of 1408 urine samples of children aged 8 - 12 showed that urine fluoride highest value 6.88 nag/L, the minimum value of 0.10 mg/L, geometric mean 1.10 mg/L. The prevalence rate of dental fluorosis for children was 36.06%. Conclusions In Luoyang city, numbers of coal-burning endemic fluorosis villages are less than before, children's dental fluorosis has significantly declined, however some people still use kitchens connecting with bedrooms and lack smoke-free facilities, they need to be educated to change lifestyle and improve furnace to reduce soot fluoride pollution.

OBJECTIVETo explore the role of inflammatory reaction mediated by p38-mitogen activated protein kinase (p38-MAPK) signal path on prevention and treatment of Parkinson disease (PD) model rats by electroacupuncture (EA).

METHODSThirty-two healthy male SD rats were randomly divided into a normal group, a sham operation group, a model group and an EA group, eight rats in each one. The PD model was established in the model group and EA group by subcutaneous injection of rotenone in skin-back area (2 mg/kg, dissolved in sunflower oil, 2 mg/mL in density), while the injection of sunflower oil emulsion without rotenone at the same point and quantity as the model group was applied in the sham operation group. The normal group was not given any intervention. The EA treatment (continuous wave, 2 Hz in frequency, 1 mA in intensity, 20 min) was applied at "Fengfu" (GV 16) and "Taichong" (LR 3) in the EA group, once a day for continuously 14 days. No treatment was given in the other groups. The expression of tyrosine hydroxylase (TH), phosphorylated p38-MAPK, cyclooxygenase-2 (COX-2) in the substantia nigra were detected with immunohistochemical method.

RESULTSThere was typical PD ethology change in the model group. Compared with the normal group and sham operation group, the expression of TH positive neuron in the substantia nigra in the model group was significantly decreased, while the expression of phosphorylated p38-MAPK and COX-2 were significantly increased (all P < 0.01). Compared with the model group, the expression of TH positive neuron in the EA group was apparently increased, while the expression of phosphorylated p38-MAPK and COX-2 were significantly decreased (all P < 0.01).

CONCLUSIONThe EA therapy could obviously reduce the expression of inflammation mediator COX-2, inhibit the phosphorylation of p38-MAPK, reduce the damage of dopaminergic neurons in the rats with PD, and this effect may be related with the impact of p38-MAPK signal path

BACKGROUNDIt is known that excessive release of glutamate can induce excitotoxicity in neurons and lead to seizure. Dexamethasone has anti-seizure function. The aim of this study was to investigate glutamate-dexamethasone interaction in the pathogenesis of epilepsy, identify differentially expressed genes in the hippocampus of glutamate-induced epileptic rats by mRNA differential display, and observe the effects of dexamethasone on these genes expression.

METHODSSeizure models were established by injecting 5 microl (250 microg/microl) monosodium glutamate (MSG) into the lateral cerebral ventricle in rats. Dexamethasone (5 mg/kg) was injected intraperitoneally at 30 minutes after MSG inducing convulsion. The rats' behavior and electroencephalogram (EEG) were then recorded for 1 hour. The effects of dexamethasone on gene expression were observed in MSG-induced epileptic rats at 1 hour and 6 hours after the onset of seizure by mRNA differential display. The differentially expressed genes were confirmed by Dot blot.

RESULTSEEG and behaviors showed that MSG did induce seizure, and dexamethasone could clearly alleviate the symptom. mRNA differential display showed that MSG increased the expression of some genes in epileptic rats and dexamethasone could downregulate their expression. From more than 10 differentially expressed cDNA fragments, we identified a 226 bp cDNA fragment that was expressed higher in the hippocampus of epileptic rats than that in the control group. Its expression was reduced after the administration of dexamethasone. Sequence analysis and protein alignment showed that the predicted amino acid sequence of this cDNA fragment kept 43% identity to agmatinase, a member of the ureohydrolase superfamily.

CONCLUSIONSThe results of the current study suggest that the product of the 226 bp cDNA has a function similar to agmatinase. Dexamethasone might relax alleviate seizure by inhibiting expression of the gene.
