BACKGROUND: As indicated by previous researches, aluminium (Al) could affect learning and memory of animals through many approaches in cluding affecting the stable status of intracellular calcium, decreasing protein kinase C(PKC) activity, and affecting the release of glutamic acid(Glu) . The formation of long-term potentiation(LTP) weakens in hip pocampal CA3 region of rats fed by forage containing Al. It could be found that Al would weaken evoked potential(EP) in hippocampal CA3 region and inhibit LTP formation, which might be related with the damaging effect of Al on L-Arg-NO approach through further application of acute Al administration, i.e., AlCl3 is directly injected into hippocampal CA3 region by microinjection.OBJECTIVE: To investigate the damaging effect of Al on learning and memory, and its correlation with cholinergic system and gamma-aminobutyric acid (GABA) system.DESIGN: A completelyrandomized controlled verifying study based on the experimental animals.SETTING: Department of psychology in a university and the medical college of an occupational technology college.MATERIALS: The study was conducted in the Laboratory of Neuro-Electrophysiology, the Faculty of Physiology, Tongji Medical College,Huazhong University of Science and Technology between September 2000 and April 2001. Totally 68 SD rats of ordinary grade in either gender with a body mass between 150 g and 250 g were obtained from the Department of Experimental Animals of Tongji Medical College, Huazhong University of Science and echnology.INTERVENTIONS: SD rats were randomly divided into 9 groups including normal NS ( NS ) control group ( n = 6): 1 μL of NS was injected twice ( 1 minute interval) into hippocampal CA3 region by microinjection; NS + AlCl3 group( n = 6): 1 μL of NS and 0.5 mol/L of AlCl3 were injected(1 minute interval) into hippocampal CA3 region by microinjection;NS + Tac group( n = 6): 1 μLof NS and 1 × 10-9 mol/L of Tacrine were injected in turn into hippocampal CA3 region by microinjection; NS + Bic group(n=6): 1 μL of NS and 1 × 10-3 mol/L of Bicuculline were injected in turn into hippocampal CA3 region by microinjection; Tac +AlCl3 group: 1 μL of 1 × 10-9 mol/L( n =8),1 × 10-10 mol/L ( n = 6) and 1 × 10-8 mol/L of Tacrine were firsdy injected into hippocampal CA3 region by microinjection, and 1 μL of 0. 5 mol/L AlCl3was injected 1 minute later; Bic + AlCl3 group: 1 μL of 1 × 10-3 mol/L( n = 9) and 1 × 10 -4 mol/L( n = 7) of Bicuculline were firstly injected into hippocampal CA3 region by microinjection, and 1 μL of 0.5 mol/L AlCl3 was injected 1 minute later. Population spike(PS) in hippocampal CA3 region was recorded after using single pulse to stimulate perforating fiber(PF). When PS became stable, medication was injected into hippocampal CA3 region to observe the impacts of Al on EP in hippocampal CA3 region and the impacts of some central transmitters on the effect of Al in in hibiting PS.MAIN OUTCOME MEASURES: PS evoked in hippocampal CA3 region;the impacts of Al on EP in CA3 region and the impacts of some central transmitters on the effect of Al in inhibiting PS. RESULTS: ① After the application of 0.5 mol/L of AlCl3 in hippocampalCA3 region by microinjection, the recorded amplitude of PS reduced to peakat 1 minute, which accounted for(33.8 ± 11. 0) % of the level beforemedication( n = 6). The inhibitive effect of AlCl3 lasted for 120 minutes. ② After the pre-application of 1 × 10-9 mol/L of Tacrine(cholinesterase in hibitor) into CA3 region by microinjection and the application of AlCl3 at oneminute later, it was found that Tacrine antagonized the inhibitive effects ofAlCl3 on PS within 1 to 30 minutes( n = 8) . Its antagonism would extend to60 minutes if 1 × 10-8 mol/L of Tacrine was administrated( n = 6) . How ever, the antagonism of 1 × 10-10 mol/L of Tacrine was weaker than that of 1×10-9 mol/L group within 3-5 minutes(n=6) ③ After thepre-application of 1 × 10-3 mol/L of Bicuculline into CA3 region by mi croinjection and the application of AlCl3 at one minute later, Bicucullinecould partially weaken the effects of AlCl3 within 1 to 20 minutes( n = 9). CONCLUSION: Al of certain concentration can inhibit the evoked PS am plitude in hippocampal CA3 region; Tacrine can antagonize Al' s effects andits antagonism might be related with dose. Hence, the inhibitive effects of Almight be related with the damage in Ach transmitter system. The applicationof Bicuculline, a GABAA inhibitor, also can weaken the PS inhibitive effectsof Al, which indicates that the inhibitive effect of Al also might be effective through GABA approach.

Reviewing the literatures about adverse reactions induced by traditional Chinese medicine injections (TCMI) reported on CNKI from 1983 to 2013. Analyzing the causes of adverse reactions induced by TCMI from its quality standards. Provide ideas for improving security of TCMI and completing its quality standards. This review indicates that TCMI-induced adverse reactions have little relationship with the number of compositions, but have tight connection with chemical ingredients and solvents. Adverse reactions can be decreased by perfecting the quality standards of TCMI.

Objective To explore the clinical characteristics and effects of thrombolytic and anti coagulation treatment in over 70 year old patients with pulmonary thromb embolism(PTE). Methods The clinical findings, diagnostic techniques, effects of thrombolytic therapy and anti coagulation in 58 over 70 year old patients with PTE were analyzed retrospectively. Results Deep venous thrombosis (DVT) in lower limbs (74 1%) was the most common thrombolism prone factors in our study. Limitation of movement and long term stay in bed due to a variety of causes were in the next place. The clinical findings were atypical, associated with a false diagnostic ratio of 46 5% in elderly patients with PTE. Undefined causal and different degree of dyspnea along with sudden and persistent hypoxemia were the main characteristics. Spiral CT and radioactive nuclear ventilation perfusion scan were important methods for diagnosis of PTE with positive finding of 95 7% and 62 5%, respectively. The effective and cure rate of thrombolytic therapy combined with anti coagulation, anti coagulation and anti platelet therapy was 91 3%, 75 8%, 0 and 47 8%, 17 2%, 0, respectively. Conclusions The most common risk factors of PTE in the elderly was DVT and the long term stay in bed or stay without active moving. The clinical symptoms were not only atypical but also variable. Thrombolytic with anti coagulation therapy is safe and effective, but anti platelet coagulation alone is not benefit.

OBJECTIVEE23K polymorphism in KCNJ11 gene is associated with cardiovascular disease and diabetes. In order to explore the mechanism of E23K correlation to related diseases, the effect of E23K polymorphism in KCNJ11 gene on membrane current was investigated.

METHODSThe exon of KCNJ11 was obtained by PCR amplification and the G-->A mutation was completed by overlap extension PCR. The sequences of KCNJ11 exon contained 23E or 23K was inserted into pcDNA3.1/CT-GFP vector respectively. The recombinant plasmid, pcDNA3.1-KCNJ11(E) and pcDNA3.1-KCNJ11(K), were transfected into HEK293T cells by lipofectamine and the membrane current density was determined by whole-cell patch clamp technique.

RESULTS1,173 bp sequences of KCNJ11 gene's exon were amplified by PCR and the recombinant expression plasmid, pcDNA3.1-KCNJ11(E) and pcDNA3.1-KCNJ11(K), were constructed successful. Positive and negative currents were detected in HEK293T cells transfected with difference plasmid by whole-cell patch clamp technique. Results showed that the reversed voltage was 50mV. The current in HEK293T cells with pcDNA3.1-KCNJ11(E) was significantly greater than that with pcDNA3.1-KCNJ11(K) (P < 0.05, n = 10).

CONCLUSIONThe polymorphism of E23K in exon of KCNJ11 gene changed the membrane currents in HEK293T cells. It could be an experiment support for the possible mechanism between the locus and related diseases.

This study was aimed to evaluate the reliability and validity of the Traditional Chinese Medicine Self Rate Health Assessment Questionnaire (TCM-SRHAQ). A total of 859 middle age and aged cases were enrolled in a cross-sectional study, which were evaluated by the questionnaire. The salivary level of ɑ-amylase was tested at the same time. The results showed that the split-half reliability coefficient was 0.91, which can highly differentiate the health level of the crowd. The spearman correlation coefficients between items in the “spleen deficiency” sub-scale were all higher than 0.3. While the correlation coefficients between items were less than 0.25. Salivary level of ɑ-amylase was used as indicator. The “spleen deficiency” sub-scale showed high validity in identifying spleen-qi deficiency people from healthy people. It was concluded that TCM-SRHAQ showed good reliability and validity in this study, which indicated it can be used as a valuable measurement for assessing different types of health status, especially the spleen-qi deficiency type.
