Methods By plant tissue culture technology, the effects of various carbon source, NAA, and active carbon at different concentration on the rhizomatous formation of B. chinensis in vitro were studied. Results MS+6-BA 2.0 mg/L+NAA 0.5 mg/L+6% white sugar was the optimal medium for the rhiz-omatous formation of B. chinensis in vitro. Active carbon should not be added to the medium. The germination rate of rhizomatous in vitro was 61.03% on the MS + BA 2.0 mg/L+3% white sugar. Conclusion Sugar concentration is the main factor of the influence on the rhizomatous formation of B. chinensis in vitro.

BACKGROUND:Studies have shown that human umbilical cord mesenchymal stem cel s can improve pulmonary ventilation function by reducing inflammations. OBJECTIVE:To observe the therapeutic effect of human umbilical cord mesenchymal stem cel transplantation on acute lung injury. METHODS:Thirty Sprague-Dawley rats were randomized into normal group, model group and experimental group. Rats in the latter two groups were used to establish animal models of acute lung injury by intratracheal instil ation of lipopolysaccharide. One hour after modeling, rats in the experimental group were intratracheal y administered human umbilical cord mesenchymal stem cel suspension (0.1 mL, 1×106 cel s), and those in the other two groups were given normal saline in the same dose intratracheal y. Twenty-four hours after treatment, the pathological changes of lung tissue were observed using hematoxylin-eosin staining;the wet and dry weight ratio of the lung tissue and the levels of serum interleukin-1 and interleukin-8 were detected. RESULTS AND CONCLUSION:Compared with the normal group, the wet and dry weight ratio of the lung tissue and the levels of serum interleukin-1 and interleukin-8 were significantly increased in the model group (P<0.05), while compared with the model group, these levels were significantly decreased in the experimental group (P<0.05). Hematoxylin-eosin staining results showed clear alveolar space structure with complete alveolar septum in the normal group. In the model group, the alveolar septum was markedly thickened, and there was visible pulmonary capil ary hyperemia, edema, as wel as a large amount of inflammatory cel infiltrations in the pulmonary capil aries and alveolar space. Edema fluid rich in proteins was observed in a part of the pulmonary alveoli, and an extensive transparent membrane formed in the alveolar space. In the experimental group, the alveolar structure was clear, but the alveolar septum became thickened, and red blood cel s and a smal amount of infiltrated inflammatory cel s were leaked from the pulmonary interstitial tissue. In conclusion, human umbilical cord mesenchymal stem cel transplantation for treatment of acute lung injury can reduce inflammatory factor levels and al eviate lung injury.

Objective To study the molecular pathologic features of CD71 and the correlation between CD71 expression and IgA deposit in IgA nephropathy(IgAN),and to investigate the role of CD71 in pathogenesis of IgAN in order to direct the therapeutic strategies.Methods According to clinical manifestations and pathological diagnosis,170 cases of renal biopsy were divided into IgA deposition nephritis(primary group),non-IgAN with IgA deposition(secondary group)and no IgA deposited nephritis(control group).Immunofluorescence double-staining using TRITC-conjugated anti CD71 antibody and FITC-conjugated anti-human IgA antibody was performed to illustrate the expression of CD71 and IgA respectively by confocal microscopy.Results No CD71 expression was found in control group,while the CD71 was positively expressed in primary and secondary groups to various levels.The intensity of expression of CD71 in primary group was more intense than that in the secondary group.The expression of CD71 in the IgAN tissues correlated closely with the accumulation of IgA.CD71 and IgA were distributed in mesangial area and capillary lumina of glomeruli of IgAN(primary group).The study showed that CD71 expression and IgA deposition were co-localized under confocal fluorescence microscopy.Conclusion CD71 is highly expressed in the glomeruli of primary IgAN.The expression of CD71 in the IgAN tissues correlats closely with the accumulation of IgA.CD71 and IgA are co-localized under confocal fluorescence microscopy.The present study reveals that CD71 is one of IgA receptors and involves in the course of IgAN.The results suggests that CD71 may play an important role in immunopathogenesis of IgAN.

The aim of this study was to investigate the role of adhesion molecules P selectin (CD62P) in the pathogenesis of primary nephrotic syndrome (NS) and its relationship with its different pathological types. The expression of CD62P in renal biopsy tissue and peripheral blood platelets from patients with NS were measured with direct immunofluorescence labelling monoclonal antibody and flow cytometry respectively. The results showed that CD62P was expressed in 140/165 cases with NS (84 8%). Among these patients, renal expression of CD62P was lower in MN and FSGS patients than that in MPGN and MsPGN patients, and even lower in MCD patients. The expression of CD62P in peripheral blood platelets of patients with NS was significantly higher than that in the normal control group( P
