Objective: To observe the effect of Yi Jin Jing (Sinew-transforming Qigong Exercises) on the muscle strength in senile sarcopenia. Methods: Sixty-five old people with sarcopenia were randomized into Yi Jin Jing group and a blank control group. Thirty-three patients in Yi Jin Jing group practiced Yi Jin Jing (Sinew-transforming Qigong Exercises), while 32 patients in the blank control group didn't receive any interventions. The muscle strength was measured before and after 12-week training. Results: During the study, each group had 1 dropout. The muscle strength was improved after 12-week training in Yi Jin Jing group, and the difference was statistically significant (P<0.05); there was no significant difference in the blank control group (P>0.05). After the intervention, there was a significant difference between Yi Jin Jing group and the blank control group in comparing the muscle strength (P<0.05). Conclusion: Constant Yi Jin Jing (Sinew-transforming Qigong Exercises) training can notably improve skeletal muscle strength in senile sarcopenia.

It proved that the probe was of highly speciality.Conclusion Reverse dot blot is a good method of quickly identification of haemophilus influenzae.

Objective To induce mice bone marrow(BM) mono-nuclear cells into dendritic cells(DC) in vitro,and then produce function vaccine of anti-myeloma by bone marrow derived dendritic cells(BM-DC).Methods Mono-nuclear cells separated from mice bone marrow were cultured in tissue culture plastics which supplemented granulocyte-macrophage clonystimulating factor(GM-CSF),IL-4.During the 8 days,there were numerous of mature DCs outgrown,and then fused with SP 2/0 myeloma cells in logarithmic growth phase cultured with 8-azaguaine by polyethylene(PEG).The resulting purified DC/myeloma hybrids were generated by selecting with hypoxanthine-aminopterin-thymidine(HAT).The specific anti-tumor activity was examined in vitro.Results Mono-nuclear cells derived from BM cultured by supplement propriate cytokines milieu in tissue culture plastics,and then exposed to lipopolysaccharide(LPS).There were plenty of mature DCs appear as early as day 8,and exhibit dramatic veils of cytoplasm and extensive dendrites in their surfaces,high express CD11c(83.19%),major histocompatibility complex(MHC)-Ⅱ(95.25%),CD86(89.24%),their capacity to stimulate primary T cell responses in mixed leukocyte reaction(MLR) would be shown strongly.Hybrids could grow well through PEG fusion and HAT selection.These hybrids could stimulate naive T cells into cytotoxic T-lymphocyte(CTLs) directed against SP 2/0 myeloma,and exhibit strong specific killed ability.Conclusions BM-DCs is fused with tumor cells ensure the tumor associated antigens could be processed and presented effectively,and stimulate specific anti-tumor immunity so that prevent or cure this kind of tumor.So it's feasible in practice to produce anti-tumor vaccine by BM-DCs.

Objective To analyze the clinical and pathological characteristics of children with lupus nephritis(LN).Methods The data of 116 inpatients from Mar.2000 to Nov.2008 with LN were retrospectively analyzed.The clinical,immunochemical and pathological data were recorded.Renal tissue was observed by light microscopy and electron microscopy after HE,PAS,Masson and PASM staining according to WHO standards.Follow-up results showed complete remission,partial remission,disease activity,renal insufficiency and death.Results Of the 116 cases of LN,there were 27 male and 89 female with a ratio of male to female 1.03.3,and the mean age was(12.0?2.2) years.The incidence of nephrotic syndrome was 63.8 %(74 cases),and acute nephritis was 21.5%(25 cases).Class Ⅳ LN was the most frequent type(14 cases,50%) and classⅢ was next(25 cases,21.5%).In view of the outcome,rapidly progressive glomerulonephritis and class Ⅳ LN were the worst.LN was initially controlled in 96.5% of the patients.Relapses of LN were most caused by the intermittent treatment.Totally 32 cases showed different renal injury,and 6 cases progressed to death.Conclusions Renal biopsy is important to diagnosis,treatment and prognosis evaluation of LN.Long and regular treatment is important for children with LN.

Objective:To observe the clinical efficacy of Yi Jin Jing (Sinew-transforming Qigong Exercises) for primary osteoporosis in the elderly.Methods:Eighty old patients with primary osteoporosis were randomized into a Yi Jin Jing group and a medication group,40 cases in each group.The Yi Jin Jing group was intervened by Yi Jin Jing (Sinew-transforming Qigong Exercises) training,while the medication group was intervened by oral administration of alendronate sodium tablet.Prior to and after 6-month intervention,the bone mineral density (BMD) of the proximal femur,visual analog scale (VAS) and activities of daily living (ADL) were estimated.Results:There were no significant differences in the BMD of the proximal femur,and VAS and ADL scores between the two groups before the intervention (P＞0.05).After 6-month intervention,the above items all improved significantly in both groups (both P＜0.01);the improvements in VAS and ADL scores in Yi Jin Jing group were more significant than those in the medication group (P＜0.01),while the between-group difference in the BMD of the proximal femur was statistically insignificant (P＞0.05).Conclusion:Practice of Yi Jin Jing (Sinew-transforming Qigong Exercises) can effectively ameliorate the BMD in the elderly with primary osteoporosis,and it can reduce the pain and improve ADL,with a better general effect compared to oral administration of alendronate sodium tablet.

OBJECTIVETo screen the optimized methods for detection seed viability and germination rate determination of Atractylodes macrocephala, and determine the relationship between seed viability and germination rate.

METHODThere were four methods, which including 2,3,5-triphynel tetrazolilum chloride (TTC) staining, red ink staining, BTB staining and Nongjia method, to evaluate the 12 A. macrocephala local varieties'seed viability and measure their germination rate.

RESULTSeed viability of A. macrocephala using TTC staining ranked the first compared to that of other three methods. Seed viability was significantly related with germination rate using TTC method. Their correlation coefficient reached 0.915 and regression equation was also found out between seed viability (X) and germination rate (Y), which was Y = -0.083 4 + 0.995 4X.

CONCLUSIONTTC staining was the optimal method to determine A. macrocephala seed vitality. Furthermore, seed viability was significant related with germination rate of A. macrocephala.

Background Congenital heart disease (CHD) is a diverse group of diseases determined by genetic and environmental factors.Considerable research has been done on genes associated with the development of the heart.Recently,focus is on the role of transcription factor NFATc1 in the development of proper valve and septa.As part of a larger study,high density single nucleotide polymorphism (SNP) scanning was used to explore the relationship between NFATc1 gene polymorphism and susceptibility to ventricular septal defect (VSD) in the Chinese Han population.Methods One hundred and ninety-two pediatric patients with congenital VSD and 192 matching healthy control subjects were studied.The haplotype reconstructions were calculated by PHASE2.0 software.Haploview software was used to perform linkage disequilibrium assessment and define haplotype blocks.The algorithm used for defining the blocks was the confidence interval method.Results The NFATc1 gene region can be divided into 11 haplotype blocks.Strong linkage disequilibrium existed within blocks 6,8,9,and 11.Three SNPs (rs7240256,rs11665469,and rs754505) within the NFATc1 gene had significant correlation with VSD by single marker association analysis.In addition,two haplotypes correlated with VSD.Conclusions NFATc1 is associated with the occurrence of VSD and it may be a predisposing gene to CHD in Han Chinese.This finding has set a direction for further genetic and functional studies.
