Microbiology experiment existing independently from microbiology theoretical curriculum is an indispensable compulsory course in contemporary life science. This article presents the principle applied by the National Excellent Microbiology Course teaching group in Nankai University, which is to strengthen the undergraduates’ basic skills of conducting microbiology experiments. With an aim to enhance the core competitiveness of the undergraduates, we have established the three-level experimental contents. A new multilevel teaching pattern focusing on basic skill training as the cornerstone has been applied to enhance the overall competences of the students and to stimulate their innovation abilities. Students’ experimental accomplishment will also be taken into consideration when their experiment results are evaluated, which helps to standardizing their research ethics.

Objective To explore the relationship between the serum level of E-selectin and S128R polymorphisms in the exon 4 of E-selectin gene and acute myocardial infarction (AMI) in local Han peoples. Method The genotype of E-selectin were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method in 168 patients with acute myocardial infarction and 200 healthy controls,and the serum level of E-selectin was measured by enzyme-linked immunosorbent assay (ELISA).Results There was significant difference in frequencies of allele and genotype in S128R polymorphism between acute myocardial infarction and control groups respectively,The relative risk suffered from acute myocardial infarction of SS genotype was 2.234 times of the SR genotype (OR=2.234,95% CI:1.112～4.437),The serum E-selectin level was significantly higher among carriers of SR genotype as compared with SS genotype (41.65?8.87)?g/L vs (34.23?6.72)?g/L,P

Metabonomics is a new method to study on the metabolic network and the relationship between body and environment, which conforms to the way of traditional Chinese medicine (TCM) research. In the study process of modernization of traditional Chinese medicine, effectively conjunction with metabonomics method will facilitate the integration of TCM with modern biological science and technology, and promote the modernization of TCM. This paper introduce the application of metabonomics in the research of toxicity mechanism of TCM, compatibility mechanism of TCM formula, pharmacology effect of TCM and processing mechanism of TCM. This paper summarize the problems in the TCM metabonomics research and prospect its bright future.

Objective To separate and amplify Hantaan virus(HV)in serum of hemorrhagic fever patients with renal syndrome(HFRS)in Heilongjiang,and look for its difference from intemational standard type strain(76-118strains).Methods HVs of different phase in the 8erum of 50 HFRS patients were separated and amplified by RTnested-PCR,its products were analyzed the amplified by sequencing.Results Detectable rate of HV in the patients serum was 36.36%(8/22)in 7 days after onset,it Was 13.04%(3/23)in patients having an onset 8 days to 14 days earlier,5 cases were not detectable 15 days after onset.Comparing the sequence of HV S gene fragment,sample 1,9,18,31,37,38,44 strain had a homology of 90.24%,86.72%,89.97%,89.16%,86.45%,87.26%and 89.43%to 76-118 strains,respectively.Conclusions The positive rate is the highset in 7 days after onset.Nucleotide sequence difference exists between pathogenic strain of Heilongjiang's HV and international standard strain,indicating that not only hosts but also locations can affect HV.

To explore the effect and mechanism of Guhong injection against cerebral ischemia reperfusion injury, SD rats were randomly divided into the sham-operated group, the model group, the nimodipine group, and high, medium and low-dose Guhong injection groups, with 10 rats in each group. The middle cerebral artery embolization (MCAO) model was established to observe neurological deficit symptoms, infarct volume, SOD activity, MDA content, GSH-Px and CAT activity in rats, as well as the contents of t-PA, PAI, TXB2 and 6-keto-PGF1α in serum. The results showed that Guhong injection could obviously promote the recovery of neurological deficit symptoms, narrow the brain infarct volume in rats after surgery, significantlyincrease the activities of SOD, GSH-Px and CAT and decrease the content of MDA. Meanwhile, it also could obviously increase the contents of t-PA and 6-keto-PGF1α and decrease the contents of PAI and TXB2 in serum, indicating that Guhong injection have better antioxidant and antithrombus effects, as well as a significant protective effect against cerebral ischemia reperfusion injury in rats.
