Though prokaryotic cells could hardly express recombinant human beta nerve growth factor (rhNGF-?) with a proper three-dimensional conformation, using of E. coli as a host for industrial production of rhNGF-? is controversial. Recombinant human beta NGF was expressed in E. coli and was refolded in vitro. The isolated products was shown to be consistent with those expressed and secreted by CHO cells in biochemical characters by SDS-PAGE, RP-HPLC, mass spectrometry, N terminal analysis and bioassay determined using DRG and PC12 cells. The products can be acquired with 95% purity, 1.8 ng/U biological activity from both expression system,which remain invariable biological activity when lyophilized in excipient and store at 37℃?2℃, RH 75%?5% for 3 months. Moreover, the product refolded from inclusion bodies of E. coli shows the predominance in homogeneity and the lower cost.

This article introduces the development history of ultrasound-assisted thrombolysis technology and operating points.It rainly focuses on the research status and application prospects of the technology in the treatment of acute cerebral infarction.

Functional dyspepsia(FD)is a commonly seen gastrointestinal disease. Dyspepsia symptom scale and quality of life questionnaire are two objective approaches for evaluating the efficacy of intervention measures on FD. This article reviewed the advances in study on evaluation of FD by dyspepsia symptom scale and quality of life questionnaire.

Diabetic cardiomyopathy is one of the main causes of death in diabetic patients.Mitochondrial dysfunction plays a key role in the development of diabetic cardiomyopathy,and mitochondrial function depends on the stabilization of the mitochondrial membrane structure.Studies on the molecular alteration and the underlying mechanism of the cardiocyte mitochondrial membrane of the diabetic heart may give us deeper insights into diabetic cardiomyopathy,and help us make a breakthrough in the therapeutic strategies.

Objective:To develop a materials management information system for military hospital warehouse of combat readiness based on RFID so as to enhance the management of military medical corps for materials of war preparation.Methods:RFID(Radio Frequency Identification) tags were attached on war materials and the information could been read by bar-code reader. SQL Server 2005 was used as the backend database, and VC# was combined with RFID to develop the software system.Results: This research has developed a materials management information system for military hospital warehouse of combat readiness based on RFID and this system could achieve informatization for information management, management of out and in warehouse, emergency plans management and forewarning management. Through manoeuvre, the average time of war materiel out warehouse has saved 12min.Conclusion: The research and development of information management system for materiel information of hospital warehouse for combat readiness has reference value for the application of researching RBID technique in material management.

Objective To investigate the clinical features and genetic tests of a case with congenital muscular dystrophy type 1A (MDC1A). Methods Clinical data of proband were collected, and genetic change were tested using next generation sequencing, and literatures pertinent to the epidemiology, mechanisms, especially genetic testing of lisencephaly were reviewed. Results A 5 year and 2 month old boy present with normal intelligence and delayed motor development, he can be sit alone but not walk at two years old. Physical examination showed normal mental reaction, muscular dystrophy, hypotonia, and joint contracture at early age. From biochemical tests, we found creatine kinase (CK) and CK-MB were increased (491U/L, 41.8U/L). EMG test suggested possible muscle-derived damage. Brain MRI showed white matter abnormality. And a heterozygous mutation (c.2045-2046delAG) inherited from his mother in LAMA2 gene, and another novel heterozygous mutation (del Exon5) inherited from his father were identified by genetic test. Conclusions LAMA2 gene deficiency can lead to MDC1A, and gene testing can help diagnosis.

Pancreatic cancer has a bad curative effect because of low rate of early diagnosis.Plasma cancer marker becomes the most ideal screening method for the special advantages.With the development of proteomics,many new plasma cancer markers,such as apolipoprotei A-Ⅱ,apolipoprotei C-Ⅰ,MBL2、ML-CK2,REG4 and so on,have been detected.The article describes the research progress of plasma tumor marker.
