OBJECTIVETo observe the effect of Jianpi Bushen Qingchang Huashi Recipe (JBQHR) on proliferation and migration of bone marrow mesenchymal stem cells (BMSCs).
METHODSBMSCs were isolated and cultured in vitro with adherence screening method to prepare cell suspension. No drug intervention was given to BMSCs in the vehicle control group. JBQHR at 0.39, 0.78, 1.56 µg/mL was added in BMSCs of low, mid, and high dose JBQHR groups for co-incubation. Its effect on the proliferation of BMSCs was detected by CCK-8. BMSCs migration and chemotactic ability was detected using Transwell method. Each dose JBQHR combined ERK kinase inhibitor U0126 was set up as control. The phosphorylation of extracellular regulated protein kinase (ERK) and CAMP responsive element-binding protein (CREB) were detected by Western blot.
RESULTSCompared with the vehicle control group, the proliferation of BMSCs and BMSCs migration number could be promoted in the 3 JBQHR groups (P < 0.05). Besides, the proliferation of BMSCs was better in mid and high dose JBQHR groups than in the low dose JBQHR group (P < 0.05). Compared with the vehicle control group, the phosphorylation of ERK and CREB could be elevated in the 3 JBQHR groups (P < 0.05), and could be inhibited by U0126 (P < 0.01). Compared with the low dose JBQHR group, the phosphorylation of ERK increased in mid and high dose JBQHR groups with statistical difference (P < 0.05).
CONCLUSIONJBQHR could promote the proliferation and migration of BMSCs, and its mechanism might be related to ERK/CREB signaling pathway

OBJECTIVETo prepare cryptotanshinone (CT)-cyclodextrin inclusion compound and improve dissolution of CT.
METHODInclusion ratio was determined by plotting the phase solubility curve of CT versus hydroxypropyl-beta-cyclodextrin (HPCD). CT-cyclodextrin inclusion compound was made by wet grinding method. Properties of the inclusion compound was investigated by in vitro dissolution test, DTA and IR spectrum.
RESULTInclusion ratio of CT versus HPCD was 1:1. Dissolution of CT-HPCD inclusion compound at 45 min was 21.6 times of material drug.
CONCLUSIONDissolution of CT was improved remarkably in CT-HPCD inclusion compound. The complexation force of the inclusion compound was hydrogen bond formed by carbonyl group of CT and hydroxyl group of HPCD.

OBJECTIVETo observe the survival of hand allograft under the state of immunosuppression and the pathological changes of rejection in the recovery process.
METHODSThe biopsies of the skin, nerve, muscle, tendon and bone tissue of hand allografts during different stages from 1 day to 7 months after operation were observed using routine histological technique.
RESULTSNo significant changes due to rejection in skin, nerve, muscle and bone tissue were observed. But different degrees of weak rejective changes were found on the wall of blood vessels; in the muscle and nerve the reactions were markedly stronger than those found in skin tissues.
CONCLUSIONSThe rejection in deep tissues should be monitored in controlling the rejection of hand allograft.

OBJECTIVE To explore the mechanism of ulcerative colitis(UC)treatment by Jianpi-Bushen Fang through pro-moting the differentiation of BMSCs in model rats.METHODS The rats were divided into 5 groups:normal group,model group,BMSCs group,BMSCs intervene group and combine group.BMSCs intervene group and combine group were injected with decoction intervened BMSCs through tail veins in vitro (1×106/mL),the combine group were also given the decoction in oral for 10 d.BMSCs group were injected with BMSCs through tail veins(1×10 6/mL).The normal and model groups were in-jected with 1 mL of normal saline through tail veins.5 rats were killed on 10th day after the intervention,respectively,for specimen.The expression of Lgr5,Ephrin-B3 and E-cadherin were detected with Western blot,and the levels of IL-6,IL-17 and TGF-βwith ELISA assay.RESULTS The expression of Lgr5 and Ephrin-B3 in treatment groups increased(P <0.05), compared with the model group.E-cadherin in treatment groups increased compared with the model group,and the combine group and BMSCs intervene group increased significantly(P <0.05).The levels of IL-6 and IL-17 in combine group and BM-SCs group significantly decreased(P <0.05),while TGF-βincreased(P <0.05).The difference between the combine group and BMSCs group was significant(P <0.05) in Lgr5,Ephrin-B3,E-cadherin,IL-6 and TGF-βexpression.CONCLUSION Jianpi-Bushen Fang can promote the venously transplanted BMSCs proliferation and differentiation into intestinal stem cell, regulate immune function and repair intestinal mucosa,which may be one possible mechanism for UC treatment.

OBJECTIVESTo determine the level of anti-Toxoplasma antibody in serum of infertile couples to explore the relationship between toxoplasma infection and infertility.
METHODSEnzyme-linked immunosorbent assay (ELISA) was applied to detect the anti-Toxoplasma antibody, antisperm antibody (AsAb) and anticardiolipin antibody (ACA) in serum of 178 couples with infertility and 190 couples who had normal pregnant history.
RESULTSThe positive result of Toxoplasma infection in the infertile couples was significantly higher than that in fertile couples which was 34.83% vs 12.11% (chi 2 = 26.72, P < 0.01) with the odds ratio 3.88. The positive result of serum AsAb in the Toxoplasma infected group was significantly higher than that in the no Toxoplasma infected group (32.50% vs 15.94%, chi 2 = 10.76, P < 0.01) with the odds ratio 2.54.
CONCLUSIONSToxoplasma infection was related to infertility. The Toxoplasma infection and was posibly related to the antisperm antibodies which can be involved in the pathogenisis of infertility.

BACKGROUNDMultidrug resistance to chemotherapeutic agents is an important clinical problem during the treatment of leukemia. The resistance process is multifactorial. To realize the total factors involved in multidrug resistance, we analyzed the differentially expressed proteins of K562 and K562/ADM cells and we investigated one of the up-regulated proteins (CRKL) using siRNA to determine its role in K562/ADM cells.
METHODSAltered protein expressions between K562/S (K562 ADM-sensitive cell line) and K562/ADM (K562 multidrug resistant cell line induced by adriamycin) were identified by 2D-DIGE coupled with mass spectrometry. Meanwhile, we confirmed the differential expression of CRKL and Stathmin in both K562 and K562/ADM cells by Western blot analysis. Furthermore, we used RNA interference to silence the CRKL gene expression.
RESULTSAmong the 9 differentially expressed proteins, 3 were up-regulated in K562/ADM cells, while 6 were down-regulated in the K562/ADM cells compared with its parent cell line. The expression of CRKL was up-regulated significantly in K562/ADM cells, and it can be decreased by recombinant lentivirus. Moreover, the multidrug resistance of K562/ADM cells was efficiently reversed by silence of CRKL gene expression.
CONCLUSIONSThe data provided the differentially expressed proteins in K562 and its resistant cell line and highlights the power of 2D-DIGE for the discovery of resistance markers in cancer. We found CRKL may be a new protein involved in the multidrug resistance of leukaemia cells.

A gene appA encoding a novel phytase was firstly cloned from Hafnia alvei by PCR and sequenced. The gene was consisted of 1335 bp, encoding 444 amino acids. The calculated molecular weight of the mature APPA was about 45.2 kD. The gene appA was expressed in E. coli BL21 (DE3). Recombinant APPA was purified and its enzymatic properties were determined. The optimum pH for the enzyme was 4.5 and the optimum temperature was 60 degrees C. The pH stability of r-APPA is good, the relative phytase activity was above 80% after treated in buffers of pH 2.0-10.0. The specific activity of r-APPA is 356.7 U/mg, and the Km value was 0.49 mmol/L and Vmax of 238 U/mg. The enzyme showed resistance to pepsin and trypsin treatment.
