Objective : To investigate the effect of aluminum exposure on expression of miR-497-5p, wingless murine breast cancer virus integration site family member 3a (Wnt3a), β-catenin protein, glycogen synthase kinase-3β (GSK-3β) protein and tau protein in rat adrenal pheochromocytoma PC12 cells, so as to provide insight into unraveling the mechanisms underlying aluminum exposure-induced abnormal phosphorylation of tau protein. Methods: PC12 cells were exposed to Al(mal)3 at concentrations of 0, 100, 200, 400 μmol/L for 24 h. The viability of PC12 cells was measured using cell counting kit-8 (CCK-8) assay. The relative expression of miR-497-5p and Wnt3a was detected using a real-time fluorescent quantitative PCR (RT-qPCR) assay, and the expression of Wnt3a, β-catenin, GSK-3β, P-GSK-3β (Ser9), tau and p-tau (Ser396) proteins were determined using Western blotting. Results : The viability of PC12 cells appeared a tendency towards a decline with the increase of aluminum dose (Ftrend=323.473, P=0.001). RT-qPCR assay detected that the relative miR-497-5p expression appeared a tendency towards a rise with the increase of aluminum dose (Ftrend=14.888, P=0.031), and the relative Wnt3a expression appeared a tendency towards a decline with the increase of aluminum dose (Ftrend=165.934, P<0.001). The miR-497-5p expression negatively correlated with the relative Wnt3a expression (r=-0.693, P=0.012). The expression of Wnt3a (Ftrend=357.656, P=0.001), β-catenin (Ftrend=208.750, P=0.001) and p-GSK-3β (Ser9) proteins (Ftrend=512.583, P<0.001) appeared a tendency towards a decline with the increase of aluminum dose, and the expression of GSK-3β (Ftrend=39.965, P<0.001), tau (Ftrend=277.929, P=0.006) and p-tau (Ser396) proteins (Ftrend=96.247, P=0.002) appeared a tendency towards a rise with the increase of aluminum dose. Conclusion Up-regulation of miR-497-5p and GSK-3β expression and down-regulation of Wnt3a and β-catenin expression may be a mechanism underlying aluminum exposure-induced abnormal phosphorylation of tau protein.

To discuss the distribution of patents' holders for Chinese herbal compounds in treating cardiovascular and cerebrovascular, the patents' holders for Chinese herbal compounds in treating cardiovascular and cerebrovascular were cluster analyzed by means of simple statistics and cluster analysis. Clustering variables were composed of patent applications, patent maintained number, related papers' quantity, etc. Chinese herbal compound patents' holders were divided into four categories according to their different scientific research and patent strength. It is the magic weapon for Chinese herbal compound patents' holders that have scientific research patents' transforming and make coordination of patent protection and scientific innovation.

Objective To determine the effects of prostaglandin E_2 alone and the combination with omeprazole for poisoning related acute mucosal lesion. Methods Forty-two healthy SD rats were randomly divided into 7 groups: control group (control), methamidophos poisoning model group (intox), 10 mg/kg omeprazole group (ome1), 50 mg/kg omeprazole group (ome2), 10 μg/kg prostaglandin E_2 group (PG1), 50 μg/kg prostaglandin E_2 group (PG2), 10 μg/kg prostaglandin E_2 combined with 10 mg/ kg omeprazole group (union). The gastric ulcer index was counted and the content of serum cholinesterase, endothelin, and tumor necrosis factor were measured, and dependability was analyzed. Results There was no obvious difference between the prostaglandin group and the poisoning model group in gastric ulcer index, endothelin, and tumor necrosis factor. The omeprazole alone and the combination treatment could improve the acute gastric mucosa lesion induced by methamidophos poisoning. Conclusion Prostaglandin E_2 alone can not obviously improve the acute gastric mucosa lesion by methamidophos poisoning. The combination with omeprazole may be a promising treatment.

Objective To study the effect of intracerebroventricular(icv) injectionon acetylcholine(ACh) on the elecric activities of pain-related neurons in the hippocampal CA1 area of rat.Methods Trains of the electric impulses applied to the right sciatic nerve were used as noxious stimuli.The discharges of neurons were led out by extracellular recording method with glass microelectrodes.Results Icv injection of ACh(20?g/10?l) caused an decrease of the evoked discharge frequency of pain-excited neurons(PEN) and a prolongation latency as well as an increase of the evoked discharge of pain-inhibited neurons(PIN) and a shortening of inhibitory duration.Conclusion The response of pain-related neurons in hippocampal CA1 area to the noxious stimulation is weakened by icv injection of ACh,exhibiting analgesic effect.

Objective To develop a system for hand function evaluation and training based on virtual reality. Methods 5DT Data Glove 5 Ultra, Visual Studio 2010 were integrated as the development environment and DirectX 9.0 as components, and the system was developed based on the MFC programming framework. Results and Conclusion The system can assess the fingers function, recognise gestures and can be used as a 3D environment for virtual training, which may guide the patients to take the training actively.

OBJECTIVE:To reduce the types of drugs which was not consistent with the accounts in monthly checking of out-patient department,reduce the wastage of dismounted drugs and improve dismounted drug management. METHODS:Through qual-ity control circle(QCC),analyzing the reasons for inconformity of accounts and drugs,adopting relevant countermeasures of staff training,cipher prescription,counter storage,managed by designated person,expiry data management and so on,the process of dismounted drug management was formulated and implemented. The types of drugs which was not consistent with the accounts and activity growth value of circle members were analyzed statistically before,during and after QCC. RESULTS:The types of drugs which was not consistent with the accounts were 33.6,21.2 and 13.6 before,during and after QCC,decreasing by 59.5%. The ac-tivity growth value of circle members were all positive value. CONCLUSIONS:QCC of outpatient pharmacy can effectively reduce the types of drugs which is not consistent with the accounts in monthly checking,standardize dismounted drug management and im-prove pharmaceutical care quality.

The lower limb rehabilitation training robots were divided into standing robots and sitting robots. Standing lower limb reha-bilitation robots included three kinds of typical structures, which mainly support body weight by suspension, and partially by air bags. Sit-ting lower limb rehabilitation robots were divided into chair and bed types, they support body weight by chairs and beds. This article re-viewed the development of products in the structures of the configuration, combined with some of the existing product and research, as well as the clinical application, .

ObjectiveTo study the effect of TGF-? 1 signal transduction blocked by antisense-Smad 4 gene on progression of experimental liver fibrosis of Kunming mice.MethodsWe transfered retrovirus-mediated antisense Smad 4cDNA into the CCl4/ethanol induced cirrhotic liver of Kunming mouse model to investigate the antisense-Smad 4 gene integration by Southern blot. The expression of Smad 4 in cirrhotic liver was observed by Northern blot, RT-PCR, and Western blot. The fibrotic degree of the livers among the three groups were compared.ResultsThe antisense-Smad 4 gene was confirmed to integrate into the liver of the retrovirus-treated mouse .In the non-treated cirrhotic liver, the expression of Smad 4 mRNA was significantly increased than normal liver, the antisense Smad 4 gene could decrease the expression of Smad 4. Compared with the non-treated liver, the fibrotic septa of the liver in the retrovirus-treated mouse were fewer,narrow, and incomplete,and their fibrotic degree of the treated-liver was reduced.ConclusionThese results indicate that antisense-Smad 4 gene can reduce the expression of Smad 4,inhibit the progression of liver fibrosis.
