The effects of flavones of epinedium brevicornum maxim (FEBM) on hemorrheological Parameters of rabbits were studied. It was found that FEBM at 0.1 or 0.4g?kg~(-1)?d~(-1)ig b. i. d. could inhibit thrombosis in vitro,at 0.4 g?kg~(-1)? d~(-1) could reduce blood mucosity at 2~40 s~(-1) shearing and inhibit agglutination of red cells. It was demonstrated that the inhibition of thrombosis and the reduction of blood mucosity might be due to the effects of FEBM on agglutination of red cells.

BACKGROUND: As a candidate gene of congenital heart disease, ACTC1 gene is related to congenital atrial septal defect inhumans.OBJECTIVE: To perform a mutation screen of ACTC1 gene in 110 nuclear families of congenital heart disease.METHODS: A case-control study was conducted based on 110 nuclear families of congenital heart disease and 300 normalhuman beings with no reported cardiac malformation. Six fragments in the coding region of ACTC1 gene was amplified by PCR invitro using five primers pairs. PCR products were screened for gene mutations.RESULTS AND CONCLUSION: A novel G-to-A variant was found at the third nucleotide of the intron downstream from exon 5.This mutation existed in a 5-year-old female with an isolated ventricular septal defect and her 30-year-old father, who had noreported cardiac anomalies. This mutation was not detected in 300 normal controls. These findings indicate that the mutation maybe related with congenital ventricular septal defects in humans.

Objective To analyze the feasibility of the recombinant cholera toxin B subunit (rCTB) as a carrier protein candidate for the preparing of polysaccharide-protein conjugate, and to discuss the immune effects of tetanus toxoid (TT) as the carrier protein in mucosal delivery vaccine. Methods The refolded pentrumer protein, rCTB was obtained by genetic engineering methods. Then conjugated the refold-ed protein with group A meningococcal polysaccharide (GAMP) using the chemical method(ADH) ,the pol-ysaccharide-protein conjugates(GAMP-rCTB) were prepared. BALB/c mice were immunized either intraper-itoneally ( i. p. ) or intranasally ( i. n. ) with GAMP-rCTB. Moreover, GAMP-TT vaccine that TT as carrier proteins was i.n. immunized to the mice. The evaluation of immunology is performed. Results The conju-gates of polysaccharide-potein with the rCTB and TT as protein carrier both are able to elicit high level of GAMP specific IgG antibody in serum after i.n. immunization, and the conjugates can also elicit specific IgA antibody in lung lavage and intestinal mucosa. Conclusion rCTB and TT can both as the protein carri-er for polysaccharide-protein conjugate as mucosal vaccine. The route of intranasal may be more ways for im-mune function than i.p. immunization when rCTB is used as the carrier of the polysaccharide-protein conju-gates.

Objective To investigate the status and needs of training medical staff in county-level medical institutions in Guangxi to provide preferences for developing training programs. Methods Self-designed questionnaires were used to investigate a random sample of 477 medical staffs in 9 county-level medical institutions including People's Hospi-tals, Chinese Medical Hospitals, Maternity and Child Care Hospitals in Wuming, Liujiang, Rongxian counties. Re-sults 13% of the medical staffs had never participated in training; 28.1% of them were trained once a month; 50.7% of them were trained for less than a week. 39.4% of them expected to receive training once a year , 21.6% expected a week to half a month and 21.8% expected three months to six months. 60.4% of them expected to receive new knowl-edge and technique training. 73.6%of them expected to go to provincial hospitals for training and 57% of them expect-ed to receive extension study. Conclusion There are differences between medical staff training needs and status. Exist-ing questions are incomplete training coverage, too dense training frequency ,too short training period, medical staffs urgently need the training of continuing professional development, new technology and professional knowledge, and training effect is not obvious. We can establish medical staff in-service training incentives ,increase medical staffing and reform training methods to encourage and attract more medical staff to attend training.

Autophagy is a highly conserved intracellular catabolic process used to degrade cytoplasmic components. In recent years, it has attracted much attention because of its importance in the pathogenesis and targeted therapy of acute and chronic kidney disease. Autophagy plays an important role in maintaining renal homeostasis under physiological and pathological conditions. The study of conditional autophagy related gene knockout specific to various renal cells has gradually revealed the role of autophagy in renal diseases. Recent studies have found that autophagy deficiency may play a key role in different pathological states of the kidney. Activated autophagy shows cytoprotective function in both glomerulus and renal tubulointerstitium, suggesting that the up regulation of autophagy may become a potential therapeutic strategy. However, there is also contrary evidence that autophagy may be harmful, which poses a great challenge to the development of therapeutic strategies for up-regulated autophagy.

【Objective】 To explore a transfusion therapeutic plan for hemolytic disease of the newborn(HDN) caused by anti-c antibodies in mother of Asian-type DEL. 【Methods】 The ABO blood type and Rh phenotype of the mother and child were determined using the saline tube method. The mother′s RhD negativity was confirmed through classical anti-human globulin testing and RhD adsorption-elution test. The mother′s unexpected antibodies were screened and their titers were measured using classical anti-human globulin testing, antibody card test and polyamine method. Cross-matching was conducted. The three hemolysis tests were performed by antibody card test. The mother′s RHD gene typing was conducted using a commercially available RHD negative identification gene detection kit (PCR-SSP method). 【Results】 The mother exhibited a CCee Rh serological phenotype, and the DEL gene test confirmed the presence of RHD*1227A, indicating the production of anti-c antibodies. The infant displayed a DCcEe Rh serological phenotype, positive for direct antiglobulin test and red cell elution. Based on the mother′s obstetric history, clinical manifestations of the infant and blood examination results, the diagnosis was HDN caused by anti-c antibodies. 【Conclusion】 For infants with HDN caused by anti-c antibodies in mother of Asian-type DEL, DCCee Rh phenotype red blood cell transfusion is recommended, while CCee Rh phenotype deglycerolized red blood cell transfusion is recommended for the mother.
