Ethnopharmacological Relevance: Acrorus tatarinowii Schott has been widely used in the treatments of neuropsychiatric and digestive disorders in clinical practices of traditional Chinese medicine for thousands of years. Both clinical and preclinical studies demonstrated antidepressant effects of A. tatarinowii.

This research was aimed to evaluate the protective effect and potential mechanism of Yiqi Tongluo Particles(YQTLs).Firstly,an animal model of multiple cerebral infarction(MCI) with Qi deficiency and blood stasis was established.Rats were randomly divided into six groups:SHAM group,Vehicle group,Buyang Huanwu decoction original group(BYHWO),EGb761 group,high and low dose of YQTLs group.

Properties of starches isolated from soft and hard wheat dough after freezing/thawing (F/T) treatment were investigated. Significance of results was observed between isolated hard wheat starch (HWS) and soft wheat starch (SWS), but both cultivars showed an increase in the amounts of damaged starch and leaching proteins, lipids, and amylose with F/T cycles. The freezing-treated HWS exhibited a higher swelling power and peak, trough, breakdown and final viscosity than SWS after F/T treatment.

As an outstanding representative of traditional Chinese medicine(TCM) prescriptions accumulated from famous TCM doctors' clinical experiences in past dynasties, classical TCM excellent prescriptions (cTCMeP) are the most valuable part of TCM system. To support the research and development of cTCMeP, a series of regulations and measures were issued to encourage its simplified registration. There is still a long-way to go because many key problems and puzzles about technology, registration and administration in cTCMeP R&D process are not resolved.

Background: Lynch syndrome (or HNPCC) is a colorectal cancer syndrome caused by germline mutations in either one of the DNA mismatch repair (MMR) genes hMLH1, hMSH2, hMSH6 or hPMS2. Mutations in hMLH1 and hMSH2 are most prevalent. Here we aimed to determine the cancer risk of MMR gene mutation carriers and, in addition, the efficacy of colonoscopy surveillance in Chinese Lynch syndrome family members with and without MMR gene mutations.

Objective: To investigate the expression of Cyclooxygenase (COX)-2 and the relationship between cox-2, mismatch repair gene (MMR) proteins and microsatellite instability (MSI) in HNPCC.

Methods: Twenty-eight cases of adenomas and 14 cases of carcinomas were collected from 33 HNPCC families patients by colonoscopy. Sporadic adenomas (n = 32) and carcinomas (n = 24) were used as a control group.

Aim: To study the characteristics of mismatch repair gene mutation of Chinese hereditary non-polyposis colorectal cancer (HNPCC) and hMLH1 gene promoter methylation, and to improve the screening strategy and explore the pertinent test methods.

Methods: A systematic analysis of 30 probands from HNPCC families in the north of China was performed by immunohistochemistry, microsatellite instability (MSI), gene mutation and methylation detection.

Results: High frequency microsatellite instability occurred in 25 probands (83.

Objective: To investigate the mutations of the mismatch repair genes hMLH1 and hMSH2 in hereditary nonpolyposis colorectal cancer (HNPCC).

Methods: The DNA samples of 76 probands of HNPCC families underwent PCR amplification and sequencing on 35 exons in hMLH1 and hMSH2 genes.

Results: (1) The overall mutation rate of the hMLH1 and hMSH2 genes was 33% (25/76).

Objective: Hereditary non-polyposis colorectal cancer (HNPCC) syndrome is the most common cause of hereditary colorectal cancer with an early age of onset. Microsatellite instability (MSI) and germline mutation in one of the DNA mismatch repair (MMR) genes are found in the majority of HNPCC families and provide an opportunity for genetic diagnosis and prophylactic screening. The MMR gene mutation spectrum may vary across different populations and be influenced by founder mutations that prevail in specific ethnic groups.
