BACKGROUND:Bone marrow stromal stem cels transplanted into infracted cardiac tissue can inhibit and reduce myocardial apoptosis, but whether this effect is correlated with improvement in cardiac function is stil unclear. OBJECTIVE:To study the early effect of bone marrow stromal stem cels transplanted into the ischemic myocardium on the cardiac function. METHODS: Models of acute myocardial infarction were established by ligation of the left anterior descending branch, while no ligation was done in the sham group. In the transplantation group, rat bone marrow stromal stem cels (0.1 mL, 2×106 RESULTS AND CONCLUSION:At 3 days after cel transplantation, myocardial apoptosis was more evident in the infarct and ischemic zones of the model group than the sham group; the number of apoptotic myocardial cels was significantly lower in the infarct and ischemic zones of the transplantation group than the model group. Compared with the sham group, the mean arterial blood pressure and left ventricular systolic pressure were ) were injected into five sites on the edge of infarcted myocardial tissues at 30 minutes after myocardial infarction. In the sham group and model group, the same volume of normal saline was injected into the myocardial tissues. Three days after cel transplantation, hemodynamic monitoring, echocardiography, TUNEL assay were employed to detect myocardial apoptosis. significantly reduced, the left ventricular end diastolic pressure was increased, and the left ventricular ejection fraction and shortened fraction were significantly lowered in the model and transplantation groups (P < 0.05), but there was no difference between the model and transplantation groups (P > 0.05). These findings indicate that myocardial apoptosis can be reduced but the cardiac function cannot be improved in acute myocardial infarction rats at early stage after bone marrow stromal stem cels transplantation.

BACKGROUND: Icari n as one of the main components of Epimedium has an inhibitory effect on osteoclasts.. OBJECTIVE: To further investigate the influence of icariin on the root absorption of the maxil ary first molar at mesial part during orthodontic treatment in rats. METHODS: Orthodontic root resorption models were established in the left maxil a of rats. Local injection of 200 mg/kg icari n (icari n group) or normal saline (positive control group) was administrated into the left first molar buccal periosteum. The right maxil a of rats served as negative control group that was treated with neither appliance nor drug injection. The mesial distance between bilateral first molars and the contralateral maxil ary incisor was measured before and after the appliance was placed. Mesial surface of the mesial root of bilateral maxil ary first molars was observed using scanning electron microscope. RESULTS AND CONCLUSION: Mesial movement of the maxil ary molars in the icari n group was significantly less than that in the positive control group (P < 0.05). Under the scanning electron microscope, smal absorption lacunae were scattered in the icari n group, while the positive control group showed a large amount of absorption lacunae and they were interconnected into a sheet, showing a stark contrast with the smooth root surface of the negative control group. It is indicated that icari n can inhibit root resorption caused by orthodontic treatment, while reducing the amount of mesial movement of the molar under corrective force.

ObjectiveTo evaluate the effects of all-trans retinoic acid(ATRA) on melanin content,activity and protein expression of tyrosinase,mRNA expression of Cu/Zn superoxide dismutase(SOD) in A375 cells irradiated with ultraviolet B(UVB).MethodsCultured A375 cells were classified into 6 groups:ATRA+UVB group treated with ATRA after UVB irradiation,hydroquinone+UVB group treated with hydroquinone after UVB irradiation,UVB group and ATRA group treated with UVB irradiation and ATRA respectively,negative control group receiving no treatment.Melanin content and tyrosinase activity were determined by NaOH solubilization assay and dopa-oxidation assay respectively at 24,48 and 72 hours after the addition of ATRA into medium.Western blot was performed to detect the protein expression of tyrosinase,and real-time quantitative PCR to measure the mRNA expressions of tyrosinase and Cu/Zn SOD in A375 cells after 24-hour culture with ATRA.ResultsThe melanin content and tyrosinase activity decreased in UVB-irradiated cells after being treated with ATRA for 24,48 and 72 hours.The protein (gray scale) and mRNA (2-△△Ct value) expression levels of tyrosinase were 0.72 ± 0.070 and 1.400 ± 0.135 respectively at 24 hours after UVB irradiation,decreased to 0.42 ± 0.056(P ＜0.01) and 0.810 ± 0.062(P ＜ 0.01 ) respectively after additional treatment with ATRA.The mRNA expression level of Cu/Zn SOD was 0.323 ± 0.066 in A375 cells at 24 hours after UVB irradiation,and increased to 0.625 ±0.103 (P ＜ 0.01 ) after additional treatment with ATRA.ConclusionATRA can suppress UVB-induced increase in melanin synthesis and elevate Cu/Zn SOD level in A375 cells,likely through tyrosinase pathway.

Objective: To detect the expression of CDX2, COX-2, and NF-κB in the tissues of gastric carcinoma (GC), precancerous lesions, and normal gastric mucosa and to in vestigate the correlation among CDX2, COX-2, and NF-κB. Methods:Data on the expression of CDX2, COX-2, and NF-κB were evaluated using immunohistochemistry in 60 cases with GC, 45 cases with precancerous lesions, and 20 cases with normal tissues. The protein levels in different pathological tissues, as well as their correlation with GC, were analyzed. Results:The positive rates of NF-κB and COX-2 proteins were significantly higher in GC group than those in precancerous lesion and normal tissue groups (P<0.05). CDX2 was expressed in GC and precancerous lesion groups but poorly expressed in the normal mucosa. The positive rate of CDX2 expression was significantly higher in precancerous lesion group than that in GC group (P<0.01). NF-κB expression was positively correlated with COX-2 in GC (P<0.01), whereas CDX2 expression was negatively correlated with COX-2 and NF-κB in GC (P<0.01). Conclusion:CDX2, COX-2, and NF-κB are possibly correlated with one another, and they cooperate during the onset, progression, and metastasis of GC.

As a member of nuclear receptor superfamily, farnesoid X receptor (FXR) has been shown to regulate numerous metabolic pathways, which include playing an important role in bile acid metabolism, maintaining lipid and glucose homeostasis when FXR is activated. With the prevalence of the glucose and lipids disorder, FXR attracts increasing attention. It may be a potential target for the treatment of type 2 diabetes mellitus and lipid disorders.

ObjectiveTo establish a central nervous system axonal mechanical transection model in vitro and observe the axonal regeneration style and speed following the transection. MethodsThe cortical explants the mice were cultured in vitro,of which the axon and dendrite parts were marked using immunofluorescence.The model was built by mechanically transecting the axons and removing the severed axons.The axonal regeneration style was observed by tracing the undeveloped cellular bodies adhering to the residual axonal surface.The growth speed of the regenerated axons and normal axons were measured as well.Results ( 1 ) After mechauically transecting the axons of explants,the axonal regeneration was largely founded at the transected line.The undeveloped cellular bodies went over the transected line and spread to the distal area with axonai regeneration. (2) The axonal growth speed was (118 ± 32) μm/d and (72 ±41) μm/d in the transection group,but was (41 ± 17) μm/d and (32 ± 19) μm/d in the control group at 24 and 48 hours respectively. ConclusionThe regeneration style of the transected axons is the extension of the axonal stumps,rather than sprouting growth,and the growth speed is faster than that of the normal axons.

Objective To establish a model fit for axonal regeneration research after its mechanical injury.Methods Cortical explants from mice were planted on culture dishes by microglass pipettes or routine glass pipettes.The cell body and dendrites in axonal area were detected by immunofluorescence and RT-PCR.Besides,purity of regenerated axons was also tested by immunofluorescence and RT-PCR after mechanical transection of axons under microscopy.Results Compared with explants planting by routine glass pipettes,in the outside 1/2 axons of explants planted by micro-glass pipettes,the immunofluorescence and RT-PCR showed negative nucleus and dendrites.In the regenerated axons following mechanical transection of explants planted by micro-glass pipette,the immunofluorescene and RT-PCR showed no regenerated axons nucleus mixed into the dendrites and nucleus.Conclusions Explants planted by micro-glass pipette obtains enough pure axons and regenerated axons.The establishment of models of axonal mechanical transection lays foundation for its molecular study after trauma.
