Alzheimer's Disease (AD) is a chronic neurodegenerative disease that usually takes many years from preclinical phase to prodromal phase characterized by mild symptoms before the onset of dementia. Once diagnosed with AD, the brain is already severely damaged and the disease will process quickly to the most severe stages since there is no medications that reverse the neuronal injuries in the brain. Thus, simple, inexpensive, and widely available methods for detecting potential AD patients during their preclinical phases are urgently needed. In such case, olfactory testing may offer a chance for early diagnosis of AD. However, there are limitations in these olfactory tests due to the complexity of the brain areas it extends to and the frequently olfactory fatigue occurred in the behavioral olfactory tests. Great efforts have been done epidemiologically to investigate the correlation between olfactory functions and possibility of developing AD. Different patterns of olfactory dysfunction have been found in AD at early stages and even mild cognitive impairment (MIC), but the cause of the dysfunction remained unclear. Various kinds of AD animal models have been used in the field to clarify the existence of olfactory dysfunctions and thus study the underling mechanism of the dysfunction. In this review we discuss (1) the function of Tau physiologically and pathologically; (2) the genetic background and biological characteristics of the most commonly used Tau transgenic mice; (3) the structural and molecule basis of olfaction; (4) the possible relationship between Tau pathology and olfactory dysfunction. Finally, we suggest that the tau transgenic mouse models may be helpful in studying the possible mechanisms of the dysfunction.

OBJECTIVETo study the effects of Citalopram on the mRNA expression of bax and bel-2 in frontal cortical neurons and on cell apoptosis of rats after stress.

METHODSTwenty-four healthy male SD rats were randomly divided into three groups (n = 8). The control group did no receive any treatment, the stress group was subject to stress and given normal saline and experimental group was given Citalopram irrigation stomach after stress. Rats were forced to swim to establish chronic stress model (15 min/d, 4 weeks), bax, bcl-2 mRNA expression were tested by in situ hybridization technique (ISH), TUNEL assay was used to determine cell apoptosis, Nikon image analysis software were used to measure the number of positive cells in each index.

RESULTSCompared with the control group, the stress group showed a larger number of bax mRNA expressing cells( P < 0.01), a smaller number of bcl-2 mRNA expressing cells (P < 0.01), and the staining intensity of positive cells was significantly reduced( P < 0.01). Compared with the stress group, the experiment group showed more reduced number of bax mRNA positive cells( P < 0.01) and significantly increased bcl-2 mRNA positive cells( P < 0.05), a small amount of positive cells were found, compared with that in the stress group, nuclear condensation in the experimental group was reduced significantly and the staining was obviously weaker( P < 0.01).

CONCLUSIONCitalopram significantly antagonizes bax mRNA and potentiatesbcl-2 mRNA protein expression and inhibits apoptosis of rat prefrontal cortical neurons caused by chronic stress, which might be one possible mechanism of Citalopram for prevention and treatment of psychosis caused by chronic stress.

The present study aimed to investigate the effect of Glomus versiforme and Trichodema harzianum on the growth and quality of Salvia miltiorrhiza continuous cropping under field conditions. The field plot experiment was conducted, these active components in the plant were analyzed by HPLC, the root diseases incidence rate of S. miltiorrhiza determined by observation and counting, and relative parameters were measured. The data was statistically processed. The result showed that inoculation of G. versiforme and combined inoculation of G. versiforme with T. harzianum significantly decreased the root diseases incidence rate of S. miltiorrhiza, and combined inoculation of G. versiforme with T. harzianum was better than other treatments. All treatments improved accumulation of active ingredients in root. Inoculation of G. versiforme and combined inoculation of G. versiforme with T. harzianum significantly increased the content of salvianolic acid B and cryptotanshinone of root (P < 0.05), Inoculation of G. versiforme, T. harzianum and combined inoculation of G. versiforme with T. harzianum significantly enhanced the content of tanshinone I and tanshinone II(A) of the root (P < 0.05). It may conclude that inoculation of G. versiforme and combined inoculation of G. versiforme with T. harzianum can effectively reduce the root diseases incidence of continuous cropping S. miltiorrhiza, and improve the quality of S. miltiorrhiza.
