Alzheimer's disease (AD) is the most frequent type of dementia in elderly,which has been regarded as a neurodegenerative disease.The traditional point of view considers that AD and vascular dementia are two different types of dementias both from their pathogenesis and treatment;however,in recent years,a growing body of evidence indicates that the vascular factors are playing an important role in the development and occurrence of AD.This article reviews cerebral ischemia and its risk factors including the effects of hypertension,diabetes,and cholesterol in the development and occurrence of AD,so as to provide new strategies in preventing,and delaying the occurrence and progression of AD.

Insertion of foreign genes into the genome map of Chinese herb always produces the intended beneficial effects, but also the unintended effects. Analysis of genomic function and metabolic end products based on the principle of substantial can reveal the influence on the quality of herbs, which is able to provide valuable refer-ence for the following evaluation on pharmacology and toxicology.

After 28 foreign species of AM fungi were inoculated in sterilized soil, the effects of the AM mycorrhizal colonization and the medicine quality of Paris polyphylla var. yunnanensis were observed by combination of inoculation test in pot at room temperature and instrumental analysis. The results showed that, compared with control group (CK), the inoculation of foreign AM fungi in the soil influenced the spore density, mycorrhizal infection rate, and colonization intensity of AM fungi in root system of P. polyphylla var. yunnanensis. The inoculation of foreign AM fungi enhanced the mycorrhiza viability of P. polyphylla var. yunnanensis by increasing the activity of succinic dehydrogenase (SDH) and alkaline phosphatase (ALP) in intraradical hyphae. The content of single steroid saponin in rhizome of P. polyphylla var. yunnanensis showed variation after P. polyphylla var. yunnanensis was inoculated by different foreign species of AM fungi, which was beneficial for increasing the medicine quality; however, the kinds of steroid saponin showed no difference. In a degree, there was a selectivity of symbiosis between P. polyphylla var. yunnanensis and foreign AM fungi. And we found that the Claroideoglomus claroideum and Racocetra coralloidea were best foreign AM fungi species for cultivating P. polyphylla var. yunnanensis under field condition.

Objective To evaluate the role of spinal Toll-like receptor 4 (TLR4) signaling pathway in the development of inflammatory pain in rats.Methods Thirty-six adult male Sprague-Dawley rats were divided into 3 groups (n=12 each) using a random number table:control group,inflammatory pain group and TLR4 signaling pathway inhibitor epigallocatechin gallate (EGCG) group (EGCG group).Inflammatory pain was induced by injecting 50 μl of complete Freund's adjuvant (CFA) into the ankle joint cavity of the left hindpaw of rats anesthetized with isoflurane.At 1-3 days after injection of CFA,EGCG 30 μg was intrathecally injected once a day in group EGCG.At 1,3 (30 min after intrathecal injection),5and 7 days after injection of CFA,the mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured.The ipsilateral L4.5 segments of the spinal cord were removed at 3 days after CFA injcction for determination of TLR4 expression (by Western blot) and contents of tumor necrosis factor-alpha (TNF-oα),interleukin-6 (IL-6) and IL-1β in the spinal dorsal horn (by enzymelinked immunosorbent assay).Results Compared with control group,the MWT was significantly decreased and the TWL was shortened at each time point after injection of CFA,the expression of TLR4 in the spinal dorsal horn was up-regulated,and contents of TNF-α,IL-6 and IL-1β in the spinal dorsal horn were increased in inflammatory pain group (P< 0.05),and no significant change was found in the parameters mentioned above in EGCG group (P>0.05).Compared with inflammatory pain group,the MWT was significantly increased and the TWL was prolonged at each time point after injection of CFA,the expression of TLR4 in the spinal dorsal horn was down-regulated,and contents of TNF-α,IL-6 and IL-1β in the spinal dorsal horn were decreased in EGCG group (P<0.05).Conclusion Spinal TLR4 signaling pathway is involved in the development of inflammatory pain in rats.

In this paper, the varying pattern of the amount of rhizospheric microorganisms, including bacteria, actinomycetes and fungus, was observed during the cultivation of Paris polyphylla var. yunnanensis. And the correlations between number of rhizospheric microorganisms and the quality of P. polyphylla var. yunnanensis were also studied. The results showed that the rhizospheric microorganism source of P. polyphylla var. yunnanensis was rich. The distribution of rhizospheric microorganisms (soil bacteria, fungus, actinomycetes, potassium-solubilizing bacteria, inorganic phosphorus-solubilizing bacteria, organic phosphorus-solubilizing bacteria) collected from different origin places existed significant difference (P < 0.05). The varying pattern for the amount of rhizospheric microorganisms was showed as following: the amount of bacteria > the amount of actinomycetes > the amount of fungus. The medicinal quality of P. polyphylla var. yunnanensis was influenced by their habits, and the increase of cultivation years caused the obvious decrease of the quality of P. polyphylla var. yunnanensis. Therefore, the increase of cultivation years will cause the variation of the soil micro-ecology flora, and decrease the nutrient absorption and the utilization of P. polyphylla var. yunnanensis, which will make the decrease of the medical quality of P. polyphylla var. yunnanensis.

Objective To explore protective effect of Heme oxygenase-1(HO-1) on irradiation-induced endothelial cell apoptosis.Methods Human endothelial cell line EA.hy926 were administered with or without HO-1 activator Copp and/or HO-1 inhibitor Znpp,respectively.Then,cells were treated with or without 8 Gy radiation.The HO-1 protein expression of cells were assessed with Western blotting and apoptosis of cells treated with irradiation were evaluated with flow cytometry.Moreover,cytochrome C releasing into cytosol were also determined by Western blotting. Results In PBS+R group,HO-1 protein expression of EA.hy926 was low posterior to irradiation.When cells were preconditioned with Copp and/or Znpp,then recieved with 8Gy irradiation,the HO-1 protein expression of EA.hy926 increased significantly in comparision with the PBS+R group(P

Objective To investigate the status and needs of community nurses' education in Changzhou,and to provide evidence for improving quality of further training.Methods Totally 402 community nurses from 72 community hospitals in Changzhou were recruited in the survey and finished the questionnaires.Results 73.1% of community nurses continue to degree education after work,79.3% of them have attend the post training.98.7% of them considered post training is necessary,and only 35.6% were willing to participate in training.Age and whether received community nursing education are the most important influence factors (OR =0.541,P =0.001 ; OR =2.430,P =0.003).In the need of knowledge and skills,there were significant differences in the age groups ( F =3.074,P =0.028).Conclusions Teaching reform is necessary.Increasing the training of young community nurses backbone is imperative and giving full play to the advantages of high qualification community nurses.

OBJECTIVETo analyze the parameters of urodynamic tests for patients with type-III B prostatitis and evaluate the significance of the results of urodynamic tests in the choice of therapies for this disease.
METHODSUrodynamic tests were performed for 87 type-III B prostatitis patients aged 22-45 (30.7 ± 8.5) years, who had moderate or severe lower urinary tract symptoms (LUTS) and failed to respond to routine therapy. Different treatments were administered according to the results of urodynamic tests followed by observation of the therapeutic effects.
RESULTSUrodynamic abnormalities were found in 70 of the 87 patients, bladder outlet obstruction in 28 (32.2%), detrusor overactivity in 25 (28.7%), bladder hyperesthesia in 18 (20.7%), low compliance in 10 (11.5%), detrusor-external urethral sphincter dyssynergia in 1 (1.1%), and impaired detrusor contractile function in 1 (1.1%). Treatments achieved obvious effectiveness in 26 cases (29.9%), effectiveness in 51 (58.6%), and no effectiveness in 10 (11.5%).
CONCLUSIONUrodynamic tests contribute significantly to the choice of therapies for type-III B prostatitis patients with moderate or severe LUTS.
