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.

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.

The production conditions of glutathione with shaking flask fermentation by the mutant Saccharomyces J-X25, a methionine-defected strain were studied, and the optimum culture conditions are as follows: initial pH6. 0, temperature 30℃, 100ml in 500ml flask, the inoculum size 10% and agitation rate 220r/min. The emphasis was on the stimulating effect on the cells by dioxogen and the sodium lactate as surfactant. Both of which were added at the logarithmic phase of fermentation, and the GSH production was up to 0. 253g/L , 52% higher than the control without the additions. Compared with the production of GSH initial strain that by the mutant in optimum conditions was increased by 79%.

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.

Objective To investigate the association factors affecting the course of IVF/ICSI-ET. Methods The clinical data of 348 cycles of IVF/ICSI-ET in patients with different causes of infertility were analyzed retrospectively. Results Ovarian reserve and response to stimulation declined with aging. The ability of bFSH predicting ovarian response was low. E 2 peak concentration, number of big follicle and retrieved oocytes decreased significantly when bFSH concentration evelated. The number of big follicle and retrieved oocytes obviously increased with the E 2 peak concentration increasing. The number of antral follicle and volume of ovary were positive relation with ovarian response. None of the factors above could predict the outcome of IVF indenpedently. Conclusion Age was strongly associated with ovarian reserve and response. The bFSH level was one of the indices reflecting ovarian reserve, and had the limited capability for predicting ovarian response and IVF outcome.E 2 peak concentration could not predict the IVF consequence. The number of total antral follicle and volume of ovary were the most direct index reflecting ovarian response. The conditions of patients should comprehensively be evaluated to raise the pregnant rate of IVF.

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, .

Objective To systemically discuss the role of Parvalbumin (PV), Calretinin (CR) and Calbindin-D28k (CB)-containing GABAergic interneurons in the acute onset and development of temporal lobe epilepsy.Methods Immunohistochemistry method was used to detect the changes of PV, CR and CB-containing interneuron numbers in hippocampus of temporal lobe epileptic rats induced by lithium-pilocarpine at different time points (6 h, 24 h, 7 d, 15 d, 30 d and 60 d).Results Compared with control group, no loss of PV-positive cells was observed in CA3 region at any time point in epileptic model groups, while dramatic reduction of PV-positive cells was seen in CA1 region ( P0.05). In CA1 region, the number of CB positive interneurons decreased dramatically at 6 h ( P
