BACKGROUND: Previous research has demonstrated that bone marrow mesenchymal stem calls (BMSCs) differentiate into varying mesoderm-derived mesenchymal cells, such as myocardial cells.OBJECTIVE: To investigate the feasibility of construction of engineered myocardial tissues with polylactic-co-glycolic acid (PLGA) olymer and cardiomyocyte-like cells derived from BMSCs in vitro.METHODS: BMSCs were isolated from bone marrow of SD rats by density gradient cantrifugation. The third passage cells were induced with the culture medium including 5-aza for 4 weeks. After successful induction, the cells were trypsinized and suspended, then the cell suspension was added to the polylactic-co-glycolic acid square slowly and cultured in the incubator for 14 days. The morphological changes were observed before and after induction under phase contrast microscope. The cardiomyocyte-like cells were identified by immunofluorescanca staining. The naked eyes were used to observe the morphology of engineered myocardial tissues. The ultrastructures of the engineered myocardial tissues were viewed with a transmission electron microscope.RESULTS AND CONCLUSION: BMSCs of primary culture formed cell colonies at 14 days. The passaged cells were larger than those of primary culture. After induction by 5-aza, the cells presented long spindle and aligned in parallel. The expression of specific proteins of cardiac troponin Ⅰ (cTnl) in induced BMSCs was positive. Transmission electron microscopy showed that the engineered myocardial tissues had myofilaments, Z line-like substances. With PLGA and cardiomyocyte-like cells derived from BMSCs, the engineered myocardial tissues which resemble native cardiac tissues can be successfully constructed in vitro.

Experience mode of marine medicine (EMMM) is the summary of experiences on marine medicine con-cluded by ancient doctors for thousands of years. The mining of EMMM is very important for the clinic application and development of marine medicine. However, these experiences are very difficult to discover for they are all scat-tered in the large number of ancient documents. We proposed that the EMMM can be built by the procedure of in-formation of ancient documents, text-mining of ancient documents, and associate network of informatics unit of ma-rine medicine by non-interactive literature-based knowledge discovery methods, and expert evaluation at the end, so as to provide database for the clinic application and further development of marine medicine.

Document resources of TCM treatment on hypertension play an important role as references and guidance. Agile construction thinking, architecture based on MVC, and data demand driven will make the building of information service system with efficiency and high quality. The content provided by this information service system will promote the scientific research and clinical practice of hypertension.

Objective: To analyze the effect of cardiac resynchronization therapy (CRT) in patients with chronic heart failure (CHF) combining left bundle branch block (LBBB) conformed to new diagnostic standard. Methods: A total of 19 CHF patients who received CRT in our hospital from 2005-06 to 2013-05 were studied. The patients were divided into 2 groups: True LBBB group,n=13 patients conformed to new diagnostic standard and False LBBB group, n=6 patients conformed to traditional diagnostic standard. Pre- and Post-operative LVEF, LVEDD, QRS duration (QRSd) and IVMD were compared in all patients; post-operative LVEF, LVEDD, QRSd, IVMD and Tmsv16-SD, Tmsv16-Dif were compared between 2 groups. Results: The post-operative LVEF, LVEDD, QRSd and IVMD were improved than pre-operative condition in both groups. Compared with False LBBB group, the improvements were more obvious in True LBBB group as LVEDD by mm (5.95±0.72 vs 7.13±0.78), IVMD by ms (22.45±8.00 vs 27.63±13.09), and QRSd by ms (140.38±5.80 vs 153.68±14.38), all P<0.01. The post-operative LVEF and Tmsv16-SD, Tmsv16-Dif were similar between 2 groups. Conclusion: CHF patients combining either true or false LBBB could be beneift from CRT, while the patients with true LBBB may receive better clinical outcomes from CRT.

This study was aimed to analyze the research status of marine medicine in China. The research hot issues and feature rules were summarized in order to discuss development trends for the clinic application and further development of marine medicine in recent 20 years. The CNKI library was used as a source to retrieve literatures on marine medicine. The bibliometric methods and Cytoscape 3.1.1 were used to analyze. The results showed that 582 papers were included. A total of 260 papers were published during 2010 to 2014. And 52 papers were published annually. 266 papers in this field were funded. The papers were mostly published in theChinese Journal of Marine Drugs. A total of 278 research institutes were engaged in the research. And the institute published the most paper was the Ocean University of China. There were 12 researchers who had published more than 5 articles. This study focused on the keywords with highly frequency, which were marine drugs, chemical composition, marine natural products, fingerprints and antitumor. It was concluded that marine medicine had become hot issues. The core of the group has been formed. However, most researches had focused on natural products and pharmacological aspects. Traditional Chinese medicine (TCM) theory had not been taken seriously and the infrastructure was weak, which obstructed the clinical application of marine medicine. We should expand the discovery and study of knowledge on ancient herbal literature as well as clinic application of marine medicine in order to build the knowledge database of marine medicine and experience mode of clinic application.

Objective To observe the application of mtDNA COI genes in common sarcosaphagous flies species identification. Methods 30 sarcosaphagous fly samples were indentified by morphological method which collected in different regions belonging to 2 families, 4 genera and 6 species. MtDNA was extracted for the PCR amplification reaction in COI gene. The PCR products were purified through agar gel electrophoresis and sequenced. Sequences of 498 bp in COI gene were disposed by multiple-alignment software of DNAMAN. Sequences divergence of 498 bp between and within species of COI gene were processed by software of MEGA. Results It was showed that there is a certain sequence differences between the 30 samples from 6 species. The intraspecific and interspecific divergence of sequence variation ranged from 0.1% to 1.6% and 2.2% to 11.2% respectively. All the species can be identified successfully by this method. Conclusion Species identification of sarcosaphagous flies can be conducted by sequence analysis and phylogenetic tree of COI gene. This method can be effectively used in fast and accurate identification in forensic entomology.

Objective To assess the efficacy of combination of Jiehe pellet and the standardized anti-tuberculosis therapeutic regimen for pulmonary tuberculosis complicating cervical lymph node tuberculosis in the aged. Methods A total of 103 aged patients with pulmonary tuberculosis complicating cervical lymph node tuberculosis were enrolled and randomly allocated to either a standardized anti-tuberculosis therapeutic regimen group (control group with 51 patients) or a standardized anti-tuberculosis therapeutic regimen plus Jiehe pellet group (treatment group with 52 patients). The patients in the control group and the treatment group received the treatment with 2HRZE/4HR and 2HRZE/4HR plus Jiehe pellet for 6 months, respectively. The abscessed lymph nodes were treated by either total excision or incision and drainage after 4 weeks of medicine treatment in both groups. Sputum smear was examined for acid-fast bacilli. The CD8 cells expressing natural killer T cells receptors NKG2A, NKG2D in peripheral blood were detected by flow cytometry. The treatment outcome was measured at the end of treatment. Results The rates of lesion resolution (78.85%vs. 58.82%;χ2=4.439, P<0.05) and cavity closure (62.86% vs. 35.48%;χ2=3.893, P<0.05) in the treatment group were significantly higher than those in the control group. In the end of 2, 4 and 6 months of treatment, cumulative rates of sputum conversion from positive to negative in the treatment group were significantly higher than those in the control group (χ2 were 5.343, 5.067 and 4.118,all P<0.05). The CD8 cells expressing NKG2A after treatment in the treatment group were significantly lower than those before treatment in the treatment group (t=9.510, P<0.01) and after treatment in the control group (t=9.832, P<0.01);the CD8 cells expressing NKG2D after treatment in the treatment group were significantly higher than those before treatment in the treatment group (t=10.622, P<0.01) and after treatment in the control group (t=10.433, P<0.01). The serum levels of IL-6 and TNF-αafter treatment were significantly lower than those before treatment in both groups (t were 17.344 and 21.142 in the treatment group, 10.984 and 12.203 in the control group;all P<0.01 );the serum levels of IL-6 and TNF-α after treatment in the treatment group were significantly lower than those after treatment in the control group (t were 7.832 and 5.478,all P<0.01). The serum IL-10 levels after treatment were significantly higher than those before treatment in both groups (t were 12.454 in the treatment group, 7.934 in the control group; all P<0.01 ); and the serum IL-10 level after treatment in the treatment group was significantly higher than that after treatment in the control group (t=4.720, P<0.01). The effective rate for cervical lymph node tuberculosis in the treatment was significantly higher than that in the control group (88.5%vs. 64.7%;χ2=6.855, P<0.01). Conclusion Combination of Jiehe pellet and the standardized anti-tuberculosis therapeutic regimen may improve immune function, increase the rate of sputum conversion from positive to negative, and facilitate lesion resolution in aged patients with pulmonary tuberculosis complicating cervical lymph node tuberculosis.
