Objective: To establish a multiplex PCR-microarray method for detecting important enteropahogens.Methods: Uniplex and multiplex PCR were performed to obtain the best primer sets for identifying the target bacteria at species and multi-species level.Fluorescent dyes were mixed into PCR reaction to determine whether it can affect the efficiency of amplification.To improve the efficiency of microarray,a 35 pairs primer-labeling system was optimized based on the hybridization results to find the best combination to avoid false negative results.Results: Specific PCR products were all obtained using species-specific primer sets.More preferential amplification may happen when more primer pairs were added to the reaction.The hybridization results showed a positive association between the efficiency of multiplex-PCR and signal intensity.Conventional PCR yielded more products than fluorescent dyes labeled PCR.Thirty-five primers were divided into three different combinations to label target respectively,hybridization results showed a high specificity.Conclusion: Mixing fluorescent dyes into PCR may reduce the efficiency of amplification and hybridization,but may have no effect on the analysis of hybridization results.The hybridization efficiency of microarray depends on the amplification efficiency of multiplex PCR.For microarray target labeling,three primer sets could be used to avoid negative hybridization led by preferential amplification of multiplex-PCR.It indicates that the multiplex PCR-microarray method is an attractive diagnosis tool for the high-throughput identification of enteropathogenic organisms especially for multiple causative agents and epidemiological investigations.

AIM:To investigate the therapeutic and preventive effects of paeoniflorin ( PF) on APP/PS1 mice, and to explore the possible mechanism. METHODS:Fifteen male 5-month-old APP/PS1 non-dominant mice were chosen as normal control group, 15 male 5-month-old APP/PS1 double transgenic mice were used as model group, and 15 male 5-month-old APP/PS1 double transgenic mice treated with 5 mg/kg PF by intraperitoneal injection were allocated in administation group. The learning and memory ability of the mice in each group was detected by Morris water maze. The apoptosis was assessed by TUNEL fluorescence staining. The protein expression of PI3K, Akt, p-PI3K, p-Akt, caspase-3, caspase-9, Bcl-2 and Bax in cerebral cortex and hippocampus was detected by Western Blot. The protein expression levels and distribution of caspase-3 and caspase-9 were detected by immunohistochemistry. RESULTS:(1) Compared with nor-mal control group, the learning and memory ability declined in APP/PS1 model group. Compared with APP/PS1 model group, PF obviously improve the ability of learning and memory in mice. (2) Compared with normal control group, the ap-optosis of nerve cells in APP/PS1 model group significantly increased and distributed in wider areas, while that in PF group was reduced (P<0.05). (3) Compared with APP/PS1 model group, PF could significantly lower pro-apoptotic factors, caspase-3, caspase-9 and Bax (P<0.05), and increase the expression of anti-apoptotic factors, p-PI3K, p-Akt and Bcl-2 (P<0.05). CONCLUSION:PF can up-regulate the expression of Bcl-2 and down-regulate the expression levels of caspase-9, caspase-3 and Bax via the activation of PI3K/Akt pathway, thereby inhibiting the nerve cell apoptosis and pro-tecting the nerve cells, so as to treat neurodegenerative diseases.

OBJECTIVETo investigate the distribution of pathogenic C.albican genotype and Candida species in association with the severity of vulvovaginal candidiasis (VVC).
METHODSPolymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) of the internal transcribed spacer analysis was employed to identify the Candida species isolated from the vaginal secretions of 198 patients with acute VVC. SSCP and GeneScan analyses of microsatellite locus I polymorphism were used to determine the genotypes of the clinical isolates of C. albican associated with VVC. All the patients were scored for clinical signs and symptoms to evaluate the severity of VVC.
RESULTSA total of 198 Candida strains were isolated from VVC patients, including 140 (70.7%) C. albicans strains and 58 (29.3%) non-albicans strains. In the 95 patients with severe VVC and 103 with mild-moderate VVC, C.albican was detected in 62.1% and 76.6% of the patients, respectively (P=0.011). Thirty-eight microsatellite locus I genotypes were detected in 140 unrelated C. albican strains, among which the dominant genotypes 30-45 (44 strians, 31.43%) and 32-46 (23 strains, 16.43%) were the most common, followed by genotypes 30-46 (4 strains, 2.86%) and 32-47 (9 strains, 6.42%). The overall frequencies of the 4 genotypes were significantly higher in severe VVC than in mild-moderate VVC cases (77.9% vs 42.0%, P<0.001).
CONCLUSIONC. albicans remains the most common pathogenic Candia species in patients with VVC, but the non-alibcans species seem more likely to cause severe VVC. The dominant genotypes of C. albicans with a tropism for the vagina are correlated to the severity of VVC.
