Objective To prepare complex material—hydroxyapatite/silicone rubber (HA/SR) used in filling parenchyma and to measure and analyse its mechanical properties, looking for proper proportion of material. Methods The complex material was mixed based on different proportion (the HA/SR mass ratio of 23%, 33.3% and 41%), and its respective properties were tested according to national standard and performed statistical analysis. Results With the increasing proportion of hydroxyapatite in complex material, the rigidity of complex material enhanced gradually, but the mechanical property decreased. Conclusion If the HA/SR mass ratio was 23% to 33.3%, the mechanical properties of complex material are equal to that of pure SR. If the HA/SR mass ratio was over 41%, the mechanical properties of complex material decrease so that the complex material can not be used in filling.

Objective To study the effects of embryonic neural stem cells transplantion on trauma of red nucleus neu-rons of the rats with spinal cord injury.Methods NSCs in logarithmic phage were labeled with BrdU,a Sprague Dawley rat mode of spinal cord injury (SCI) was developed with electrocircuit control spinal cord injuring device.Thirty SD rats were randomly divided into three groups: sham group,SCI group and NSC group.The NSCs were trans-planted into injured site three days after SCI.Then NSCs labeled with Brdu were detected by immunohistochemisty,rubrospinal tract (RST) neurons were labeled by retrograde transport of the horseradish peroxidase (HRP) from the lesion site,which were taken by damaged axons and remained in the neurons,then the labeled red nucleus (RN) neurons were counted.Hind limb function of experimental rats was evaluated by a blinder observer using BBB open field locomotion rating score.Results BrdU positive NSCs were detected in the spinal cord after transplantation,the number of RST neurons labeled by HRP in NSC group was more than that in SCI group (P <0.01),the BBB score of NSC group was higher than SCI group (P <0.01).Conclusion The transplanted NSCs can survive in the injured site of spinal cord and protect RN,then promote more remarkably functional recovery after SCI.

Objective To improve the detail of the surgery for cicatricial ectropion,and the the effect was investigated. Methods Based on 46 patients withⅡ,Ⅲdegree cicatricial ectropion admitted to our department,choose the junction of normal skin and scar tissue as the incision line according to the degree of ectropion and local situation,and to reserve and recover the orbicularis oculi muscle as possible. The released areas exceeded separately the external canthus and reached the level of eye fissure,take advantage of full-thickness skin graft to correct the parallel lines and make fixation to the eyelid ectropion fusion skin graft on external canthal ligament. Results After followed up for 6 months to 2 years,46 cases of eyelid skin grafts survived completely and eyelids were in good reduction,with none case of incomplete eyelid closure. Conclusion Choose the surgical incision and the released areas in a proper way to reserve the structural integrity of orbicu-laris muscle and make skin graft fixation to inner and external canthal skin can prevent effectively the recurrence of ectropion and improve surgical progress.

OBJECTIVE:To establish a method for simultaneously determination of glycyrrhizic acid and glycyrrhetinic acid in Yaotongning capsule. METHODS:HPLC was performed on the column of Agilent TC-C18 with mobile phase of methanol-0.2 mol/L ammonium acetate(gradient elution) at a flow rate of 1.0 ml/min;detection wavelength was 250 nm and column temperature was 25 ℃ and injection volume was 10 μl. RESULTS:The linear range was 0.007 1-0.178 0 mg/ml(r=0.999 8)for glycyrrhizin acid and 0.354 8-8.720 0 μg/ml of glycyrrhetinic acid(r=0.999 8);RSDs of precision,stability and reproducibility tests were no more than 1.74%,average recoveries were 95.49%-100.62%(RSD=1.98%,n=9)and 96.80%-102.26%(RSD=1.83%,n=9),respec-tively. CONCLUSIONS:The method is simple,reproducible,accurate and reliable,and can be used for the simultaneous determi-nation of glycyrrhizic acid and glycyrrhetinic acid in Yaotongning capsule.

Objective: To analyze the correlation of miR-625 expression with clinicopathological characteristics in esophageal squa-mous cell carcinoma (ESCC) and to explore the effect of miR-625 on the migration and proliferation of ESCC cells. Methods:The expres-sion level of miR-625 was determined through real-time PCR in 86 paired human ESCC tissue specimens and tumor-adjacent normal esophageal tissue specimens, ESCC cell lines, and esophageal epithelial cell line. The associations of miR-625 expression with clinico-pathological characteristics and survival in ESCC patients were analyzed. Transwell and CCK-8 assays were performed to examine the effect of miR-625 expression on migration and proliferation of ESCC cells. Results:Compared with tumor-adjacent normal specimens, miR-625 was significantly downregulated in ESCC tissue specimens (P<0.05). MiR-625 expression was decreased in ESCC cell lines com-pared with human esophageal epithelial cell lines (P<0.05). Lower miR-625 expression was associated with poorer prognosis and sur-vival. The migration and proliferation abilities of ESCC cells were inhibited by miR-625 overexpression (P<0.05). Conclusion:MiR-625 acts as a tumor suppressor gene in the development and progression of ESCC, suggesting that miR-625 may serve as an efficient prog-nosis biomarker and a potential therapeutic target for ESCC.

OBJECTIVETo investigate the effects of micro(mi) RNA-195 on high-glucose induced neonatal cardiomyocyte hypertrophy and to explore the related mechanism.

METHODSThe potential target gene of miRNA-195 (Smad7) was predicted by TargetScan5. 1 software. Cardiomyocytes were isolated from neonatal SD rats and cells were then randomly divided into three groups: cells treated by culture medium containing 5 mmol/L glucose (control group) , by culture medium containing 25 mmol/L glucose (high glucose group) and treated by culture medium containing 25 mmol/L glucose and miRNA-195 inhibitor transfection (miRNA-195 inhibitor group). After 24, 48, or 72 h of in vitro culture, the morphology of cardiomyocytes was examined under phase contrast microscope. Micrographs were captured and the cell surface was calculated. The mRNA expressions of miRNA-195 and myosin heavy chain β (β-MHC), a biomarker for cardiomyocyte hypertrophy, in cardiomyocytes were detected by RT-PCR. The protein expression of Smad7 was determined by Western blot. The concentration of transforming growth factor-β1 (TGF-β1) in the supernatant of culture medium was measured by ELISA.

RESULTSCross-sectional area of cardiomyocytes, expression of miRNA-195 and β-MHC and secretion of TGF-β1 were significantly increased in high glucose-treated cells (P < 0.05 vs. normal control). The protein expression of Smad7 was significantly downregulated in cells exposed to high glucose for 48 h (P < 0.05 vs. normal control). Downregulation of miRNA-195 partly reversed the high glucose-induced effects. The expression of Smad7 was negatively correlated with miRNA-195 in high glucose control group (correlation coefficient: -0.945, P < 0.05).

CONCLUSIONOur results demonstrate that Smad7 could be the target gene of miRNA-195. miRNA-195 might play a crucial role in the development and progression of diabetic cardiomyopathy possibly through downregulating the expression of Smad7 and modulating TGF-β/Smad pathways.
