【Objective】In-vitro antibacterial activity of the combination of Herba Violae(HV)and Herba Taraxaci(HT)in different proportions was compared and analyzed for the optimization of the combination proportion of Herba Violae and Herba Taraxaci and the influencing factors.【Methods】The minimum inhibitory concentration(MIC)of the combination of HV and HT was determined by agar double dilution method and the minimum bactericidal concentration(MBC)by broth dilution method,and bactericidal curve was traced.Meanwhile,the resistance of the combination of HV and HT induced by sub-inhibitory concentration was analyzed,and the influencing factors of in-vitro antibacterial activity were investigated.【Results】The combination of HV and HT in the proportion of 1∶4 had a better antibacterial activity on four kinds of gram-positive bacteria and on four kinds of gramnegative bacteria,and exerted an bactericidal effect on Escherichia coli and Klebsiella Pneumoniae(both MBC_(50)/MIC_(50) and MBC_(90)/MIC_(90) being 2).The bactericidal curve showed that 2?Log cfu/mL bacteria strain could be killed by the combination of the proportion being 1∶4 at 8~(th) hour,the effect being superior to that of other two combinations.Inoculation dosage,serum amount and pH value had no effect on in-vitro antibacterial activity.【Conclusion】The combination of HV and HT in the proportion of 1∶4 has a better antibacterial activity.

OBJECTIVE: To establish a practical, convenient and accurate method of DNA molecular marker for the identification of Testudinis Carapax et Plastrum. METHODS: Phenol extraction method and salting-out method were used to extract mtDNA from Testudinis Carapax et Plastrum and its adulterants. Cyt b mtDNA sequences of Chinemys reevesii and other turtle species were downloaded from GenBank. Species specific PCR primers were designed according to the differential DNA fragments of Cyt b genes, and Cyt b gene segment was amplified by PCR technique and sequenced. RESULTS: The complete 16.6 kb mtDNA was extracted from all samples by the two extraction methods. The specific primers could only amplify the Cyt b gene sequence of Chinemys reevesii, and its fragment was about 319 bp. The result of sequencing indicated that the homologous similarity was 100% with Chinemys reevesii. CONCLUSION: Salting-out method is suitable for the DNA extraction from Testudinis Carapax et Plastrum. The primers are specific to Chinemys reevesii and can be used to distinguish Testudinis Carapax et Plastrum from its adulterants. Copyright 2012 by the Chinese Pharmaceutical Association.

Objective To explore the influence of helicobacter pylori(Hp) on gastric motor function in children with chronic gastrictis.Methods Forty-seven children with chronic gastrictis were classified into Hp positive and negative groups according to Hp and histology exa-mination.Each child underwent gastric emptying test of solid by using nuclide method and electrogastrogram(EGG) examination.These cases with Hp-positive acceptted these triple eradication therapy[clarithromycin 15 mg/(kg?d),amoxicillin 50 mg/(kg?d),omeprazole 0.8 mg/(kg?d)]for 2 weeks,and underwent EGG examination again after eradicating Hp.Results The half emptying time(GET_1/2)in Hp-positive gastric group were significantly longer than those in Hp-negative group(t=6.403 P

Objective To investigate the effects of broadband ultraviolet B (BB-UVB) on the proliferation of, tyrosinase activity and melanogenesis in melanocytes.Methods Melanocytes isolated from human foreskin were subjected to primary culture.Some cultured primary melanocytes were irradiated with BB-UVB at 10, 20, 30, 40, 50, 100, 200 and 300 mJ/cm2.Then, CCK-8 assay was performed to evaluate the proliferative activity of melanocytes, dopa oxidation assay to estimate the activity of tyrosinase, and sodium hydroxide (NaOH)-lysis method was used to determine melanin content.Real-time fluorescence-based quantitative PCR was conducted to measure the mRNA expressions of genes involved in non-canonical Wnt pathways in melanocytes after irradiation with BB-UVB at 30, 50 and 100 mJ/cm2.Western blot was carried out to determine the expressions of proteins involved in non-canonical Wnt pathways in melanocytes before and after irradiation with BB-UVB of 100 mJ/cm2.The melanocytes receiving no treatment served as the control group.Statistical analysis was carried out by one-way analysis of variance followed by least significant difference (LSD)-t test for multiple group comparisons and by the independent sample t test for two-group comparisons.Results After irradiation with BB-UVB at 10-300 mJ/cm2, the proliferative activity of melanocytes was gradually reduced compared with the control group (all P ＜ 0.05), and the survival rate of melanocytes was less than 50％ when the irradiation dose of BB-UVB was higher than 100 mJ/cm2.Furthermore, tyrosinase activity gradually increased in melanocytes after irradiation with BB-UVB at 10-100 mJ/cm2 compared with the control group, and the increase was statistically significant at the radiation dose of 100 mJ/cm2 (P ＜ 0.05).Compared with the control group, the WIF-1 mRNA expression level decreased, while c-Jun N-terminal kinase (JNK), microphthalmia-associated transcription factor (MITF), Ras-related C3 botulinum toxin substrate 1 (RAC 1) and tyrosinase (TYR) mRNA expression levels increased in melanocytes after irradiation with BB-UVB at 30, 50 and 100 mJ/cm2 (all P ＜ 0.05);the WNT5A mRNA expression significantly decreased in melanocytes irradiated with 30 and 50 mJ/cm2 BB-UVB, but increased in those irradiated with 100 mJ/cm2 BB-UVB (all P ＜ 0.05).The radiation with 100 mJ/cm2 BB-UVB significantly decreased the expression of WIF-1 protein, but enhanced the expressions of WNT5A, JNK, MITF, RAC1 and TYR proteins in melanocytes compared with the control group (all P ＜ 0.05).Conclusions BB-UVB can decelerate the proliferation of, elevate tyrosinase activity and melanin level in, melanocytes.The WIF-1 gene may inhibit melanogenesis, and the decrease in its expression may promote melanogenesis by activating the JNK/MITF/TYR pathway through the combined effects of proteins involved in non-canonical Wnt pathways.

Objective To investigate relationship between different degrees of asymptomatic carotid artery stenosis and cognitive impairment. Methods The cognitive function were evaluated with the montreal cognitive assessment scale (MoCA) in 80 patients with asymptomatic carotid artery stenosis and 56 controls, the total MoCA scores and subprojects scores were compared between the patients with different degrees of ACS and controls. Results The total MoCA score, visual space and executive function, attention and delayed recall had significant difference among the mild, moderate, severe ACS patients and control group (all P < 0.05). There was no statistical significance of the total MoCA score and the scores of all subprojects between the patients of mild ACS patients and the control group (all P > 0.05). The total MoCA score and the scores of visual space and executive function , attention and delayed recall in moderate and severe ACS patients were significantly lower than the control group and mild ACS patients (P < 0.05). Furthermore, the severe ACS patients, compared with the moderate ACS patients , performed worse on the cognitive tasks which involved visual space and executive function, attention and delayed recall (P < 0.05). Conclusions Cognitive function is impaired in the patients with moderate and severe ACS,the neuropsychological characteristics are mainly impaired in visual space and executive function, attention and delayed recall.
