Agricultural Microbiology is a professional foundation curriculum for biology,botany and envi-ronmental majors in agricultural universities.After 1999,with the increase enrollment of the national under-graduate education and rapid construction of the university,the number of majors and students increased rapidly and quality of students and talent demand of society changed dramatically.Under such condition,in order to meet the society demand of microbiology,according to the distinguishing feature of different major groups,based on strengthening the basis teaching and stretching application teaching,new curriculum teaching model and method were explored positively,and then new curriculum system was constructed.Be-ing aroused sufficiently of the students’ subjective initiative,both the teaching quality and comprehensive quality were improved.

OBJECTIVETo examine the effects of sodium phenylbutyrate on the apoptosis of human tongue squamous cancer cell line and expression of p21 and survivin genes.

METHODSThe inhibition effects of sodium phenylbutyrate on Tca8113 and human tongue squamous cell carcinoma (TCSSA) cell lines were detected by methyl thiazoly terazolium (MTT) and the apoptosis of the cancer cells after being induced by sodium phenylbutyrate examined by flow cytometry (FCM). The expression of p21 and survivin genes were observed with Western blotting and RT-PCR.

RESULTSCompared with control group, the level of p21 mRNA and protein of Tca8113 cellline increased to 0.09 ± 0.08 and increased 0.72 ± 0.10, that of TCSSA cellline increased 1.34 ± 0.12 and 1.56 ± 0.09 (P < 0.05). Compared with control group, the level of surrive mRNA and protein of Tca8113 cellline decreased to 1.10 ± 0.05 and 1.14 ± 1.10, that of TCSSA cellline decreased to 0.12 ± 0.08 and 0.94 ± 0.09 (P < 0.05). Sodium phenylbutyrate inhibited the cell proliferation, promoted cell apoptosis and arrested the cells in G₁/G₀ phase. The amount of p21 mRNA and protein were increased, and the expression of survivin gene was decreased.

CONCLUSIONSSodium phenylbutyrate exhibited remarkable inhibitory effects on human tongue squamous cancer cell proliferation and induced cancer cell apoptosis. The mechanism may be due to up-regulation of p21 gene and down-regulation of survivin gene. The mRNA level of p21 gene and survivin gene showed a strong correlation.

OBJECTIVETo observe the effects of three fluid resuscitation methods on apoptosis of visceral organs in rats with hemorrhagic shock.

METHODSA model of rat with severe hemorrhagic shock and active bleeding was established in 32 SD (Sprague-Dawley) rats. The rats were randomly divided into control group, no fluid resuscitation group (NF group), controlled fluid resuscitation group (NS40 group) and rapid large scale fluid resuscitation group (NS80 group). Each group contained 8 rats. The curative effects were compared. At the same time, the apoptosis in liver, kidney, lung and small intestinal mucosa of survivors after hemorrhage and resuscitation was detected by light microscopy in HE (hematoxylin and eosin) stained tissue sections, flow cytometry and terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL).

RESULTSThe survival rate of early fluid resuscitation (14/16) was markedly higher than that of NF group (3/8). There was some apoptosis in liver, kidney, lung and small intestinal mucosa of all survivors. Compared with NF and NS40 groups, the apoptosis of liver, kidney and small intestinal mucosa of NS80 group was obviously increased.

CONCLUSIONSAmong three fluid resuscitation methods, controlled fluid resuscitation can obviously improve the early survival rate and the apoptosis of liver, kidney and small intestinal mucosa in rats with severe and uncontrolled hemorrhagic shock, and may benefit improvement of prognosis.

OBJECTIVETo investigate the effects of methanol extract of Celastrus orbiculatu (MECO) on synovial hyperplasia and cartilage erosion and degradation in rheumatoid arthritis (RA), and explore the possible mechanisms to provide clues for new drug development for RA treatment.

METHODSThe articular synovium from patients with RA and normal articular cartilage were co-implanted into the back of severe combined immunodeficient (SCID)mice to establish the chimeric model SCID- HuRAg. Four weeks later, the mice were given MECO intragastrically at 30 mg/day, leflunomide at 500 microg/day or distilled water, respectively, for 4 consecutive weeks. After completion of the treatments, the histological scores of the grafts for synovial hyperplasia, cartilage invasion by synoviocyte and cartilage degradation around the chondrocytes were evaluated, and serum level of tumor necrosis factor-alpha (TNF-alpha) was measured with radioimmunoassay. The expression of TNF-alpha mRNA and the cell apoptosis in the synovium were detected with in situ hybridization (ISH) and TUNEL, respectively, and the results were analyzed with the image analysis system.

RESULTSThe grafts survived in the mice till the end of experiment. MECO and leflunomide, in comparison with distilled water, significantly lowered the scores for synovial hyperlasia (2.00+/-0.76 and 2.25+/-0.89 vs 3.63+/-0.52), cartilage erosion (1.69+/-0.80 and 2.00+/-1.36 vs 3.75+/-0.53), cartilage degradation (1.88+/-0.83 and 2.13+/-0.83 vs 3.63+/-0.74) and serum TNF-alpha level (0.84+/-0.09 and 0.83+/-0.12 vs 0.99+/-0.11 ng/ml). Cell apoptosis of the synovium increased significantly with MECO and leflunomide treatments, but the expression of TNF-alpha mRNA in the synovium decreased significantly in MECO group.

CONCLUSIONMECO can effectively suppress synovial hyperplasia and cartilage erosion and degradation SCID-HuRAg mice by reducing TNF-alpha production in the synovium and promoting synovial apoptosis. MECO can be comparable with leflunomide in their effect, but the former is more effective in suppressing TNF-alpha expression in the synovium.

OBJECTIVETo evaluate the efficacy and safety of postoperative adjuvant chemotherapy with imatinib in gastrointestinal stromal tumor(GIST) patients who had high risk of recurrence.

METHODSA prospective, open-label, multi-center trial conducted in sixteen teaching hospitals in China was carried out. The criteria of the enrolled patients included age more than 18 years old, CD117 positive GIST, tumor size more than 5 cm, pathological mitosis counts more than 5/50 HPF, and treatment beginning within 4 weeks after complete resection and with imatinib (400 mg, once a day) for at least 12 months. The 1, 3 year recurrence rates, disease free survival, overall survival rate and quality of life were evaluated.

RESULTSFrom Aug. 16th 2004 to Sep. 13th 2005, there were totally 74 patients screened and 57 patients (34 men, 23 women) enrolled in the imatinib treatment group. The primary tumors were located in the stomach in 50.9%, the small intestine in 38.6% and the colorectum in 10.5% of the cases. All the patients received radical resection. Until the cut-off date of interim analysis, there was no evidence of tumor relapse or metastasis in all patients and no death was reported either. Among the 57 enrolled patients with intention to treat(ITT), twelve patients finished the protocol (per protocol, PP). The disease free survival was (268.3 +/-120.2) d in ITT analysis, and (396.7+/-38.2) d in the PP analysis. The incidence of adverse effect was 44.4% . The score in quality of life showed no statistically significant difference between the baseline visit and the follow-up visits.

CONCLUSIONImatinib is a promising postoperative adjuvant chemotherapy in GISTs patients with high risk of recurrence, and the adverse effects are receivable.
