To construct a secretory-expression vector of antimicrobial peptide Bactenecin 7(Bac7),and identify the secretory-expression product in L.lactis MG1363 and its bioactivity.The splicing primers of regulation elements and Bac7 gene,which designed according to codon usage preferences of L.lactis MG1363,were chemically synthesized,and the overlap-extension PCR method was used to splice the full length of Bac7 gene.Then the Bac7 gene was linked to expression vector pMG36e to construct pMG36e/Bac7 vector,and pMG36e/Bac7 was transformed into L.lactis MG1363 by electrophoration.RT-PCR and Western blot assays were applied to investigate the expression of the Bac7 gene in L.lactis,and bioactivity of Bac7 in culture supernatant of L.lactis was tested with plate-diffusion method.The results showed that the Bac7 gene and its regulation elements was amplified and cloned in the vector pMG36e successfully,The secretory-expressed Bac7 in L.lactis MG1363 harboring pMG36e/Bac7 was identified by Western blot,and it had high bacteriostatic activity against E.coli.These results indicate that the recombinant L.lactis MG1363 could express bioactive Bac7,which lays a foundation for further study of oral administration of a Bac7-secreting L.lactis to treat intestinal bacteria infection.

ObjectiveTo evaluate the effect of Bone mesenchymal stem cells(BMSCs) intraarticular injection on the pathological development of collagen-induced arthritis(CIA) rats.MethodsCIA Wistar rats were divided into 2 groups:the saline injection control group and the BMSCs injection group.BMSCs were isolated from normal rats and cultured in vitro till P2 generation,which were injected into the affected the ankle joint consequently.After 2,4,8,12 weeks of processing,the following indexes were observed:arthritis score and X-ray.Twelve weeks later,all of the rats were sacrificed and the following histological indexes were evaluated:cartilage destruction and cartilage extracellular matrix secretion.Paired samples t-test was used for the statistical comparison.ResultsAll the arthritis indexes of the BMSCs group were much lower.than those of the saline control group.The arthritis scores were 3.18±0.62 vs 3.84±0.35 (at week 2),3.45±0.28 vs 5.96±0.48(at week 4),3.86±0.23 vs 6.75±0.36(at week 8),4.23±0.43 vs 7.86±0.66 (at week 12) respectively.X-ray scores were 2.04±0.21 vs 2.72±0.15(at week 2),2.52±0.47 vs 4.06±0.38 (atweek 4),3.56±0.29 vs 4.35±0.36 (at week 8),3.73±0.43 vs 4.86±0.62(at weekl2) respectively and the histological evaluation indexes were 2.34±0.22 vs 3.52±0.55 (at week 12).ConclusionBMSCs injection may inhibit the pathological development of CIA rats,and it may be a promising approach for the treatment of rheumatoid arthritis.

To understand the family sex education for young children in rural areas of Sichuan province and analyze the influencing factors. A multi-stage random sampling method was used to select 2246 parents of kindergarten children from rural areas in Sichuan province for a questionnaire-based survey.The Chi-square test and Logistic regression model were used for data analysis. It was found 1132(52.33%)parents had implemented family sex education for young children and 1031(47.67%)had not.Young children having asked sex-related questions(=1.536,95%=1.257-1.878),parents thinking that early childhood sex education is necessary(=3.691,95%=2.029-6.717),and parents having the intention to know early childhood sex education(=1.700,95%=1.274-2.269),and kindergarten having implemented early childhood sex education(=3.316,95%=2.515-4.372)were promoting factors for parents to conduct early childhood sex education,whereas a total annual household income at the middle level(=0.664,95%=0.456-0.968)was a hindering factor for parents to conduct early childhood sex education. Parents of young children in rural areas of Sichuan province have poor awareness of sex education,and the proportion of parents who have never conducted sex education for children is high.The total annual income of the family,whether the children have asked about sex-related questions,parents' attitude towards early childhood sex education,and whether the kindergarten has conducted the early childhood sex education are important factors that influence the level of children's family sex education.

OBJECTIVERett syndrome (RTT) is a neurodevelopmental disorder occurring almost exclusively in females as sporadic cases due to de novo mutations in the methyl-CpG-binding protein 2 gene (MECP2). Familial cases of RTT are rare and are due to X-chromosomal inheritance from a carrier mother. Recently, DNA mutations in the MECP2 have been detected in approximately 84.7% of patients with RTT in China. To explain the sex-limited expression of RTT, it has been suggested that de novo X-linked mutations occur exclusively in male germ cells resulting therefore only in affected daughters. To test this hypothesis, we have analyzed the parental origin of mutations and the XCI status in 15 sporadic cases with RTT due to MECP2 molecular defects.
METHODSAllele-specific PCR was performed to amplify a fragment including the position of the mutation. The allele-specific PCR products were sequenced to determine which haplotype contained the mutation. It was then possible to determine the parent of origin by genotyping the single nucleotide polymorphism (SNP) in the parents. The degree of XCI and its direction relative to the X chromosome parent of origin were measured in DNA prepared from peripheral blood leucocytes by analyzing CAG repeat polymorphism in the androgen receptor gene (AR).
RESULTSExcept for 2 cases who had a frameshift mutation; all the remaining 13 cases had a C-->T transition mutation. Paternal origin has been determined in all cases with the C-->T transition mutation. For the two frameshift mutations, paternal origin has been determined in one case and maternal origin in the other. The frequency of male germ-line transmission in mutations is 93.3%. Except for 2 cases who were homozygotic at the AR locus, of the remaining 13 cases, 8 cases had a random XCI pattern; the other five cases had a skewed XCI pattern and they favor expression of the maternal origin allele.
CONCLUSIONDe novo mutations in sporadic RTT occur almost exclusively on the paternally derived X chromosome and that this is most probably the cause for the high female: male ratio observed in sporadic cases with RTT. Random XCI was the main XCI pattern in sporadic RTT patients. The priority inactive X chromosome was mainly of paternal origin.

non-myeloablative BuCy+fludarabine conditioning regimen,and another one was treated with TBI+VP-1 6 +CTX+CCNU conditioning regimen.Only one case received short-term MTX,cyclosporin A and ATG regimen for prevention of graft-versus-host disease (GVHD).The GVHD prevention regimens of the other patients were based on short-term MTX,cyclosporin A,ATG and mycophenolate mofetil regimen.The hematopoietic reconstitution, complications and prognosis were observed.Results One patient died of intracranial hemorrhage,and hematopoi-etic reconstitution was achieved in the other 20 patients.The median time for hematopoietic reconstitution shortened by one day in large-dose group compared with that in low-dose group.Adverse reactions included high fever, shivering,gastrointestinal tract adverse reaction,liver injury,oral mucositis and other rare side effects.GVHD occurred more frequently in patients with HLA mismatched transplantation.Nine patients with aGVHD and 9 patients with cGVHD recovered after effective treatment.Within 100 days after transplantation,18 patients had bacterial or fungal infection,mainly upper respiratory tract infection;7 patients had cytomegalovirus infection;2 had EB viremia,and one had urinary BK virus infection.Only one patient died of VOD.Hemorrhagic cystitis occurred in 5 patients and improved after treatment.The median survival time was 24 months (ranging from 136 days to 9 years).One-year and 3-year overall survival rates were 85.2% and 63.9%,the disease free survival rates were 81% and 23.8%,recurrence free survival rates were 71.4% and 14.3%,respectively.Conclusion URD-HSCT was an effective method to treat leukemia.Conditioning regimen of BuCy and modified BuCy2 were safe and effective,the adverse reactions were reversible and well tolerated.Hematopoietic reconstitution time shortened in large-dose MNC and CD34 + cell number groups compared with that in low-dose group.The occurrence rate of GVHD with HLA mismatched transplantation was more than that of HLA matched transplantation.Low-dose heparin,prostaglandin E1 and Danshen injection can effectively prevent VOD.
