Objective To understand the quality of malaria blood examinations in township?level hospitals,so as to provide the evidence for continuing the malaria blood examinations in the stage of post?malaria elimination. Methods A total of 64 township hospitals were investigated and 640 negative malaria blood slides were scored individually according to 10 indicators inMalaria Elimination Technical Schemein 2013 and 2014. The single and multiple indicators were calculated,and the work of blood examinations and situation of technicians were investigated. The data of malaria blood examinations and patient discovery in township hospitals of Nantong City were collected and analyzedduring the period of 2011-2014. Results Forthe single indi?cator,29.5%of the thick blood films did not reach the standard,and 35.8%of thin blood films did not reach the standard. For the multiple indicators,blood slides with more than 4 indicators below the standard(poor quality)accounted for 32.5%. From ma?laria blood examinations and malaria situation,the number of slides was 194 635 during the period of 2011-2014,and there were no local vivax malaria casesin 4consecutive years from 2011 to 2014,andlocal malaria has been effectively controlled in Nantong City. For health facilities where malaria patients initially presented,the township and village level accounted for 16.3%,and county and higher level accounted for 83.7%. Conclusions The quality of malaria blood examinations in township level hospitals of Nantong City is not high and the microscopic examination has a relatively low efficiency in the discovery of ma?laria cases. A new model for malaria blood examinations needs to be further explored.

Objective To investigate the action of chondrogenesis differentiation of bone marrow stromal cells (BMSCs) transfected with adeno-hTGF-β1. Methods In the experiment group, replication-deficient a denoviruses carrying human hTGF-β1 complementary DNA (adeno-hTGF-β1 was constructed and applied to transfect to the first generation BMSCs. As a control, each BMSCs was transduced with 200 pfu of adeno-LacZ gene. One day after transfer, BMSCs were trypsinized, counted, and 5×105 cells aliuots were spun down at 500 rpm per minute in 15 ml polypropylene conical tubes and then cultured in a defined medium in an incubator at 37℃ for 21 days. The aggregates were harvested at time points to 21 days and assessed by gross observation, histological analyses and immunohistochemical localization of type Ⅱ collagen. Results When harvested at 21 days, each pellet shrinked to spheroid tissue with apearly opalescence in gross morphology and found to be relatively firm. H.E staining showed elongate dlining cells appeared as perichon drium-like cells at the surface. Some nests of cartilage were observed at the substrate of the tissue. Mature chon drocytes were embeded in the lacuna in the experiment group. In addition, Safranin'O staining confirmed the presence of sulfated proteoglycans in the ECM of chondrogenesis region. Immunohistochemical staining revealed the presence of type Ⅱ collagen in chondrogenesis region. By contrast, HE staining showed no evidence of cartilage formation in the control group. They were fibrous tissue with no architectural feature. Safranin'O staining and Immunohistochemical staining showed no evidence of sulfated proteoglycans or typeⅡ collagen expression. Conclusion BMSCs transfected with adeno-hTGF-β1 could induce its chondro-genesis when aggregate cultured in a defined medium in vitro, laying a foundation for the application of hTGFβ1 gene-transfected BMSCs in cartilage tissue engineering.

Objective: To study the mechanism of jindengshanggen (JDSG) oral liquid's anti infectiion effect.Methods: inhibition on bacteria growth, resistance to Escherichia coli endotoxin and measurement of monocytic phagocaryosis in mice were taken. Results: The effects of JDSG oral liquid is probably not due to the inhibition on bacteria growth, but rather due to its stimulation on other anti infection mechanisms in human body. The enhancement of immune response and toxin tolerance may be one of the mechanisms for JDSG oral liquid to cure acute pharynx infection. Conclusions: These results provide a basis for clinical application of JDSG.

Objective To observe the effect of early occupational therapy intervention on unilateral spatial neglect caused by stroke.Methods A total of 92 patients with unilateral spatial neglect caused by stroke were ran- domly divided into a treatment group(46 cases)and a control group(46 cases).The cases of the control group were treated by routine clinical treatment plus positioning on the bed,passive joint motion,bridging movement,facilitation techniques,balance training in sitting and standing positions,gait training immediately after the patients' conditions got stable.The patients in the treatment group were treated with activities of daily living(ADL)training in addition to the interventions employed in the control group.Results Effect of the treatment group are superior to that of the control group as reflected by the scores with Fug1-Meyer scale and Barthel Index(P

We studied the effect of surfactin on cell proliferation, apoptosis and the cytoskeleton in human breast cancer cell line MCF-7 in vitro. The result of 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) showed that the surfactin inhibited proliferation of MCF-7 cells in a dose- and time-dependent manner, with IC50 at 48 h of 27.3 micromol/L. Surfactin-induced cell death was considered to be apoptotic by observing the typical apoptotic morphological changes by AO/EB staining. Flow cytometric analysis also demonstrated that surfactin caused time-dependent apoptosis of MCF-7 cells through cell arrest at G2/M phase. Immunofluorescence and Western blotting showed that surfactin significantly suppressed the expression of vimentin, induced the alpha-tubulin depolymerization and rearrangement and then the skeleton system of the cells changed dramatically. Based on our findings, surfactin can significantly inhibit the growth of MCF-7 cells and induce apoptosis.

Objective: To analyze the epidemiological characteristics of varicella epidemic situation at schools and kindergartens in Fengxian district of Shanghai during 2012-2018, and to provide evidence for developing control and prevention strategies. Methods: Data of varicella epidemic situation at schools and kindergartens and varicella cases were analyzed by descriptive methods. The rates were compared with chi-square test. Results: A total of 6 727 varicella cases were reported in Fengxian during 2012-2018, for an incidence of 85.34 per 100 000 population. Totally 66 varicella epidemic outbreaks and public health emergencies caused by varicella were reported, which involved 741 varicella cases. Among them, 426 were breakthrough cases (57.49%). The average interval time of breakthrough cases were (6.78±2.79)years, and the incidence was more concentrated in the 3-9 years after vaccination with varicella vaccine. Most breakthrough cases appeared 5 years past vaccination. The peak time of varicella was from April to June and from October to December. Most of cases were in the 5-11 year-old group and 15-17 year-old group. The cases in males was higher than in females. Kindergarten childcare and primary school children were at high risk of varicella. Timeliness of reporting was positively correlated with the duration of the varicella epidemic situation( r =0.52， P <0.05). Conclusion Most varicella epidemic situation in Fengxian district of Shanghai occued in primary schools during autumn and winter, and most of the varicella cases were breakthrough cases. Emergency vaccination of varicella vaccine can effectively control the spread of the epidemic. It is suggested to increase the publicity of the immunization program of 2 doses of varicella vaccine and raise the awareness of varicella vaccination of children’s parents.
