The sequence of Neurospora crassa(XP_322380)and Gibberella zeae PH-1(EAA76971)ribosomal protein gene were subjected to local tBlastn searching against the Chaetomium globosum ESTs datebase.The 765 bp full length cDNA encoding 60S ribosomal protein L10a gene was obtained.The open reading frame was 654 bp and encoded 217 amino acids.The protein molecular mass was 23.9 kD.The BlastP analysis revealed that amino acids sequence of ribosomal protein L10a gene from C.globosum shared 89% high similarity with N.crassa and 78% low similarty with Ustilago maydis.The cDNA and deduced amino acid sequence of 60S ribosomal protein L10a gene were accepted by GenBank(accession numbers: AY669070,AAT74578).

The time that industrial microbiology alone took the course is short,so it requires a discussion about reform on teaching content and method.The thesis first discusses the reforms on teaching content from basic theory knowledge combining to scientific research,experiment and producing practice.Then reforms the teaching method,such as adopting the computer-assisted instruction(CAI) pattern,combining the problem-based learning(PBL) and case-based studying(CBS) each other,and leading into partly bilingual education method.By all above investigation and discussion practice in two aspects,the students produces deep interest to industrial microbiology,and reached the purpose of teaching reform.

Prostate cancer (PCa) incidence is increasing in China.Because of the limited clinical symptoms,early detection of PCa is critical and difficult.Current clinical diagnostic methods for localizing PCa including both the conventional anatomic imaging and histological techniques have many problems.Enormous novel PCa specific molecular probes have been evaluated.Those probes have substantially improved the diagnostic accuracy and specificity of PCa.This review briefly introduces the conventional noninvasive imaging techniques for PCa diagnosis.Nuclear medicine probes that have great clinical value for PCa molecular imaging are also discussed.

Chimeric antigen receptor T-cell (CAR-T) therapy is an emerging cancer immunotherapy strategy in recent years. CAR-T therapy has shown significant efficacy in the treatment of relapsed or refractory diffuse large B cell lymphoma and refractory pediatric acute lymphoblastic leukemia. However, restricted by the complexity of solid tumor microenvironment, the application of CAR-T therapy in solid tumors is still underway. Molecular imaging can trace the in vivo status of T cells in real time and in depth, which is of great significance to investigate the biological behavior of CAR-T cells in vivo and to evaluate their activation status. Meanwhile, molecular imaging strategy can also act as an early predictor of CAR-T treatment efficacy and related side effects, which can provide effective information for clinical intervention and play an important role in guiding the development of CAR-T therapy.

Objective To observe the therapeutic effect of plum-blossom needle therapy and cupping therapy combined with traction on cervical spondylosis of vertebral artery type.Methods 60 patients with cervical spondylosis of vertebral artery type were randomly divided into the treatment group and control group with 30 cases in each group. The patients of the treatment group were treated with plum-blossom needle therapy and cupping therapy combined with traction, and those of the control group only with traction. The therapeutic effects of two groups were compared.Results The total effective rate of the treatment group was 83.3 %, that of the control group was 60.0%. There was a significant difference between two groups ( P<0.05).Conclusion The effect of plum-blossom needle therapy and cupping therapy combined with traction on cervical spondylosis of vertebral artery type is superior to traction therapy alone.

The full length cDNA encoding peroxisomal membrane protein from Chaetomium globosum was cloned using RACE technology and the sequence in cDNA library of C. globosum in GenBank ( Accn: BP099709). The 747bp full length cDNA encoding peroxisomal membrane protein allergen (pero) gene was assembled with 412bp 3'and 508bp 5'RACE products. The open reading frame was 501 bp encoding 166 amino acids. The molecular weight of the protein was 17. 5kDa and its theoretical isoelectric point was 5.75. The pero gene was amplified using specific primers of cDNA 5'and 3'untranslated region, sequence analysis indicated that the gene have 3 exons and 2 introns. ClustalX analysis revealed that amino acids sequence of pero gene from C. globosum and Neurospora crassa shared 83% high similarity. To construct pET28a-pero expressive plasmid, pero gene was inserted into pET28a expressive vector. Escherichia coli BL21 transformed by pET28a-pero plasmid was induced with IPTG. The protein expression was analyzed with SDS-PAGE. A 21kDa pero fusion protein representing the pero gene was expressed in recombinant E. coli BL21. The sequences of cDNA,DNA and deduced amino acid of the pero gene from C. globosum were submitted to GenBank (Accn: AY555771, AY584753,AAS66898).

Objective To label human VEGF targeted bevacizumab (avastin) with 111In and to evaluate the application of 111 In?DTPA?avastin SPECT imaging for tumor diagnosis. Methods DTPA?avastin was prepared by coupling with a bifunctional chelating agent, and then labeled with 111 In to obtain 111 In?DTPA?avastin. The stability and molecular integrity of the labeled radiotracer were studied. Human hepatoma cell ( BEL7404) bearing nude mice tumor model was employed for tumor targeting evaluation. Gamma imaging was acquired after intravenous injection of 18.5 MBq probe. At the end of the observation, animals were sac?rificed for bio?distribution study. Results 111 In?DTPA?avastin tracer was synthesized and purified to a?chieve a radiochemical purity yield above 98% and specific activity up to 185 GBq/nmol. Its stability in 5%BSA was optimal, and the radiochemical purity after incubation for 96 h was over 90%. Gamma imaging re?sults showed that the tracer possessed definite tumor targeting property. Its biodistribution was consistent with that of normal in vivo antibody metabolism while possessing a good tumor?targeting property with a relatively high uptake of (3.8±0.8) %ID/g in tumor tissues 96 h after injection. Conclusions 111 In?DTPA?avastin tracer has good physicochemical properties, in vivo stability and good VEGF targeted binding. 111 In?DTPA?avastin has potential to be a new molecular probe for SPECT imaging.
