[Effects of aminooxyacetic acid on the learning and memory ability and its possible mechanism in rats with chronic alcoholism].

Objective: To investigate the effects of aminooxyacetic acid (AOAA) on learning and memory ability and possible mechanisms in rats with chronic alcoholism.

Methods: Sixty SD male rats were randomly divided into three groups on average.The model group rats and the remedy group rats were fed with the water containing (v/v) 6% alcohol for 28 days.

[Effect of Beclin-1 shRNA on hypoxia-induced autophagy in SH-SY5Y cells].

Objective: To observe the effect of hypoxia on autophagy in Beclin-1-knockdown SH-SY5Y cells by constructing a stable transfected SH-SY5Y cell lines of silencing Beclin-1 gene.

Methods: Beclin-1shRNA lentiviral vector and negative control lentiviral vector were constructed; the vector was transfected into SH-SY5Y cells; then the expression of Beclin-1 mRNA was detected by RT-PCR, the level of Beclin-1 protein was detected by Western blot. CCK-8 method was used to determine the effect of Beclin-1 knockdown on the viability of SH-SY5Y cells.

Effects of rhein on intestinal transmission, colonic electromyography and expression of aquaporin-3 by colonic epithelium cells in constipated mice.

Constipation is one of the most common gastrointestinal diseases in the world. This study was to investigate the effects of rhein on intestinal transmission and colonic electromyography and expression of aquaporin-3 (AQP3) in the colonic mucosa of mice with constipation. The mouse model of constipation was established using the compound diphenoxylate.

Arginine vasopressin relates with spatial learning and memory in a mouse model of spinocerebellar ataxia type 3.

Spinocerebellar ataxia is an inherited neurodegenerative disorder that the most prevalent type is type 3 (SCA3). Arginine vasopressin (AVP) is released within the lateral septum for controlling the learning and memory. This communication studied the effect of AVP on the spatial learning and memory of SCA3 mice.

Enrichment of MTHFR 677 T in a Chinese long-lived cohort and its association with lipid modulation.

Background: Variants in the Methylenetetrahydrofolate reductase (MTHFR) gene may result in a lowered catalytic activity and associate with subsequent elevated serum homocysteine (Hcy) concentration, abnormal DNA synthesis and methylation, cardiovascular risk, and unhealthy aging. Several investigations on the relationship of MTHFR C677T polymorphism with serum lipid profile and longevity have been conducted in some populations, but the findings remain mixed. Herein, we sought to look at the association between MTHFR C677T and lipid profile in a longevous cohort in Bama, a well-known home of longevity in China.

Microsomal triglyceride transfer protein gene -493G/T polymorphism and its association with serum lipid levels in Bama Zhuang long-living families in China.

Background: The -493G/T polymorphism in the microsomal triglyceride transfer protein (MTP) gene is associated with lower serum low-density lipoprotein cholesterol (LDL-C) and triglyceride (TG) levels and longevity in several populations, but the results are inconsistent in different racial/ethnic groups. The current study was to investigate the plausible association of MTP -493G/T polymorphism with serum lipid levels and longevity in Zhuang long-lived families residing in Bama area, a famous home of longevity in Guangxi, China.

Methods: The MTP -493G/T was genotyped by PCR-restriction fragment length polymorphism in 391 Bama Zhuang long-lived families (BLF, n = 1467, age 56.

Cholesteryl ester transfer protein TaqIB polymorphism and its association with serum lipid levels and longevity in Chinese Bama Zhuang population.

Background: TaqIB polymorphism in the cholesteryl ester transfer protein (CETP) gene has been reported to be associated with serum high-density lipoprotein cholesterol (HDL-C) levels and longevity in several populations, but controversial results also arose probably due to racial/ethnic diversity. Bama is a remote and mountainous county located in the northwest of Guangxi, People's Republic of China, which has been well known for its longevity for centuries. The current study was to investigate the possible association of CETP TaqIB polymorphism with serum lipid levels and longevity in the Bama Zhuang population.

[Analysis of publication of West China Journal of Stomatology from 2000 to 2005].

Objective: To analyze the characteristic of publication of West China Journal of Stomatology (WCJS).

Methods: Making use of literature metrology, a comprehensive analysis of the information publication of West China Journal of Stomatology from 2000 to 2005 was made.

Results: The quantity of articles published from 2000 to 2005 in West China Journal of Stomatology was 964, the average fund paper ratio was 0.
