Saposhnikoviae Radix Enhanced the Angiogenic and Anti-Inflammatory Effects of Huangqi Chifeng Tang in a Rat Model of Cerebral Infarction.

Huangqi Chifeng Tang (HQCFT), a traditional Chinese formula of three herbs, has been used to treat cerebral infarction (CI). Saposhnikoviae Radix (SR) was designed as a guiding drug for HQCFT to improve its angiogenic and anti-inflammatory effects. In this study, TTC staining was used to detect the area of CI.

Anti-inflammation effects of the total saponin fraction from Dioscorea nipponica Makino on rats with gouty arthritis by influencing MAPK signalling pathway.

Background: Dioscorea nipponica Makino is widely used in traditional Chinese medicine to treat gouty arthritis.

Methods: Sixty male Wistar rats were divided into six groups: the normal group, model group, colchicine group (COL) and three total saponin groups (RDN) (high dose [160 mg/kg], middle dose [80 mg/kg] and low dose [40 mg/kg]). HE staining was used to detect the histopathologic changes of the synovial tissue of joint.

Molecular epidemiological characteristics of Streptococcus pyogenes strains involved in an outbreak of scarlet fever in China, 2011.

Objective: To investigate molecular characterization of streptococcus pyogenes isolates involved in an outbreak of scarlet fever in China in 2011.

Methods: Seventy-four Streptococcal pyogenes involved in an outbreak of scarlet fever were isolated from pediatric patients in the areas with high incidence in China from May to August of 2011. Emm genotyping, pulsed-field gel electrophoresis (PFGE), superantigen (SAg) genes and antimicrobial susceptibility profiling were analyzed for these isolates.

[Expression analysis and subcellular localization of an ERF transcription factor from Salvia miltiorrhiza].

Objective: A SmERF1 gene was isolated from Salvia miltiorrhiza, and expression patterns to different stress condition were analysed in the root tissues of S. miltiorrhiza.

Method: The cDNA of SmERF1 gene from S.

[An outbreak of gastroenteritis caused by contaminated well water in a village, Henan province].

Objective: To identify the cause and mode of transmission of a gastroenteritis outbreak in a village, Henan province.

Methods: Gastroenteritis patients were identified through family visits, interviewing the village doctors and reviewing diagnosis and prescription records at the village health clinic. Cases were defined as onset of one of the four symptoms from the village resident during July 20 to August 12, 2010.

[An anatomical study on lateral ligaments of rectum].

Objective: To identify the location and contents of the rectal lateral ligaments and its relationship with the middle rectal artery and pelvic plexus.

Methods: Twenty-nine pelvics of human cadavers were sagittally sectioned into 58 hemipelvic specimens. All of hemipelvics were dissected with sharp technique under direct vision by one surgeon.

[Expression of osteopontin mRNA and its clinical significance in gastric cancer].

Objective: To investigate the expression of osteopontin mRNA and its correlation with clinicopathologic features of gastric cancer and elucidate its role in tumor invasion and distant metastasis.

Methods: The expression of OPN mRNA was detected by semi-quantitive RT-PCR. The relationship between the relative content of OPN mRNA and clinicopathologic features of gastric cancer was analyzed.
