China Pharmacy 2016;27(5):657-659
OBJECTIVE:To evaluate therapeutic efficacy and safety of chemotherapy combined with Xiaoaiping injection in the treatment of elderly patients with advanced gastric cancer. METHODS:60 elderly patients with advanced gastric cancer were collected from our department during 2012-2014,and then divided into union group and single group with 30 cases in each group. Single group was given irinotecan(CPT-11)150 mg/m2 added into 0.9%Sodium Chloride injection,and union group was addition-ally given Xiaoaiping injection 80 ml,qd,on the basis of single group. A treatment course lasted for 14 days,and both groups re-ceived 4 courses of treatment. The tumor markers,disease single rate,progression-free survival (PFS) and the incidence of ADR were compared between 2 groups. RESULTS:After treatment,the levels of CEA,CA199 and CA242 in 2 groups were significant-ly lower than before;the union group was significantly lower than the single group,with statistical significance(P<0.05). The dis-ease single rate of union group was 70.00%,which was significantly higher than that of single group (33.33%). PFS of union group was(11.23±2.17)months,which was significantly longer that of single group [(9.36±0.84)months],with statistical signif-icance(P<0.05). The incidence of leucopenia,alanine aminotransferase elevation,diarrhea,stomatitis and hand-foot syndrome in union group was significantly lower than in single group,with statistical significance(P<0.05). CONCLUSIONS:Xiaoaiping in-jection combined with irinotecan chemotherapy for advanced gastric cancer has obvious effect with a low incidence of ADR.

3.Growth factors-mediated effects on the differentiation of human adipose-derived stem cells into chondrocytes.
Journal of Biomedical Engineering 2014;31(6):1409-1413
In recent years, there has been a growing emphasis on use of human adipose-derived stem cells (hADSCs) for cartilage tissue engineering owing to their ability to differentiate into chondrocytes, which is mainly induced by growth factors (GFs). In general, GFs for chondrogenic induction come from the transforming growth factor beta (TGF-beta) superfamily. To date, the most commonly used GFs for chondrogenes is TGF-beta1/3. However, the response of hADSCs to GFs may differ significantly from that of human bone marrow stem cells (hBMSCs). It has been reported that bone morphogenetic protein-6 (BMP-6) treatment induced TGF-beta receptor-I expression of hADSCs. It seems that these two cell populations varied strongly in their potency to undergo chondrogenesis in the same medium conditions. Here, we provide a concise review on various GFs used in chondrogenic differentiation of hADSCs in vitro.

4.Deguelin down-regulates the expression of cyclin D1 gene in zebrafish embroys through the whole mount in situ hybridization
Chinese Journal of Tissue Engineering Research 2015;(15):2382-2386
BACKGROUND:In the early development of zebrafish embryos, cels divide and proliferate rapidly, but low concentration of deguelin can delay the development of zebrafish embryos.
OBJECTIVE:To observe the effect of different concentrations of deguelin on cyclin D1 gene expression in zebrafish embryos.
METHODS:Though normal fertilization, zebrafish embryos that incubated to the 2-cel stage (about 0.75 hour after fertilization) and shield stage (6 hours after fertilization) were colected and put into 12-wel plates treated with 100, 200, 400 nmol/L deguelin at 28.5℃in an incubator til the shield period and 24 hours after fertilization, respectively. Simultaneously embroys treated with 1% dimethyl sulfoxide solution were as a control group, cultured in the same conditions. Cyclin D1 RNA probes were prepared for the whole mountin situhybridization, observing staining by an upright fluorescent microscope camera to detect the effect of deguelin on cyclin D1 expression in zebrafish embryos.
RESULTS AND CONCLUSION:Deguelin showed significant negative regulation on the expression of cyclin D1 gene in zebrafish embryos. Cyclin D1 expressed in outsourcing cels in embryos of shield stage, and a significant reduction in the expression of cyclin D1 came up with the increasing concentrations of deguelin. In the 400 nmol/L deguelin treatment group, there was nearly no expression of cyclin D1. Cyclin D1 expressed in the brain, central nervous system, immature eye, somites, trunk, and tail of embryos at 24 hours after fertilization, and reduced significantly in the 100 nmol/L deguelin treatment group, especialy in the proliferative area. In the 200 and 400 nmol/L treatment groups, the embryonic development slowed down signficantly, and cyclin D1 gene mainly expressed in the dorsal ectoderm cels.

Objective: To compare the effects of three fluoride-containing agents on the remineralization of deciduous teeth in vitro. Methods: 36 deciduous teeth were randomly divided into four groups with 9 in each. The teeth were fenestrated on the labial middle surface and the rest parts of the teeth were covered with red nail polish.Every exposed area was etched,rinsed and puffed.Then the exposed areas were treated with 100 g/L(NH 4) 2MoO 2F 4(group ①) , 380 g/L Ag(NH 3) 2F (group ②) and APF-LaCl 3(group ③) for 3 minutes respectively, those in group④ were treated with deionized H 2O as the controls.Then,the teeth were placed into a bottle containing 5 ml remineralization solutions. 4 days later, the concentration of Ca 2+ in the remineralization solutions was measured. Results: The Ca 2+ concentrations (mmol/L) in the remineralization solution of group ①,②,③ and ④ were 0.338 9?0.116 5,0.570 0?0.145 5,0.517 8?0.084 8 and 0.120 4?0.046 8 respectively (P0.05:②vs③). Conclusion: The results indicate that all of the three fluoride-containing agents can promote the remineralization of deciduous teeth in vitro, and that both APF-LaCl 3 and 380 g/L Ag(NH 3) 2F are more effective than 100 g/L(NH 4) 2, MoO 2 F 4.
