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 explore the effect of rehabilitation training combined with rational-emotive therapy on post-stroke depression (PSD).Methods 51 PSD patients were randomly divided into the treatment group (n=25) and control group (n=26). All patients received routine rehabilitation training, simultaneously took 20 mg of fluoxetine hydrochloride dispersible tablets per day. Based on above, the treatment group was given physiological rehabilitation treatment with rational-emotive therapy in early stage, 30 min each time, continuously 6 weeks. The two groups were assessed with Zung Self-rating Depression Scale and Fugl-Meyer Motor Scale before and after treatment.Results Afer treatment, the scoers of Zung Self-rating Depression Scale and Fugl-Meyer Motor Scale of the treatment group was higher than that of the control group ( P<0.05).Conclusion The rational-emotive therapy might improve the depression condition of post-stroke, enhance patients' motor function.

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 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.

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.

Abstract: Objective　To evaluate the free thalassaemia screening programme for preconception and pregnancy in Hainan Province, and to provide a theoretical basis for optimizing the screening process for thalassaemia. Methods From November 2020 to July 2021, a survey was conducted on 10 396 adults with Hainan household registration who participated in the Epidemiological Survey of Thalassemia in Hainan Residents in 19 cities and counties of Hainan Province. All of them underwent routine blood tests, haemoglobin electrophoresis tests and genetic tests for thalassaemia. The optimal diagnostic cut-off values for mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), and haemoglobin adult type 2 (HbA2) were determined using screening test indexes such as receiver operating characteristic curve and sensitivity. The diagnostic effectiveness of different primary screening programs for thalassemia gene carriers was evaluated. Results Using the existing MCV single-indicator thalassemia primary screening protocol in Hainan Province, where individuals with MCV<82 fL undergo thalassemia gene testing, resulted in a high missed diagnosis rate (34.06%) and low sensitivity (65.94%). The optimal cut-off values for MCV screening for alpha-and beta-thalassaemia were 84.45 fL and 79.05 fL, respectively; the optimal cut-off values for MCH screening for alpha-and beta-thalassaemia were 27.95 pg and 25.15 pg, respectively. The optimal cut-off value for HbA2 screening for alpha-thalassaemia was less than 2.55% and greater than 3.35% for beta-thalassaemia. The "combined HbA2 or MCH or MCV screening protocol" with the cut-off values recommended in this study had a better performance in primary screening for thalassemia, with the highest sensitivity (92.96%) and negative predictive value (92.67%) and the lowest underdiagnosis rate (7.04%), statistically significant differences compared with the existing protocol (P<0.05). Conclusions The current process of screening for thalassemia in Hainan Province may lead to missed diagnoses. The combined use of MCV, MCH and HbA2 for thalassemia screening, adopting locally suitable cutoff values for primary screening indicators, can improve the incidence of missed reporting of thalassemia and enhance diagnostic effectiveness.
