ObjectiveTo investigate the protective effect of erythropoietin (EPO) on human renal tubular epithelial-mesenchymal transition (EMT) induced by high glucose. MethodsCultured HK-2 cells were divided into 5 groups: normal control group, osmolarity control group, high glucose group, high glucose with EPO (5 U/ml)group and high glucose with EPO (10 U/ml)group. The mRNA expression of α-SMA, TGF-β1, Smad2, ILK of cells were measured by RT-PCR. The levels of intracellular α-SMA and TGF-β1 protein were measured by immunocytochemistry. ResultsCompared with the control groups, mRNA expression of α-SMA, TGF-β1, Smad2, ILK and protein expression of α-SMA and TGF-β1 were increased after high glucose treatment (P<0.01). Compared with the high glucose group, EPO 5 U/ml or EPO 10 U/ml remarkably down-regulated the expression of α-SMA, TGF-β1, Smad2 and ILK (P<0.01). ConclusionEPO can inhibit the progression of EMT and the up-regulation of TGF-β1, Smad2 and ILK induced by high glucose.

OBJECTIVETo investigate the effect of the anticoagulants on PRP quality, so as to clarify the appropriate anticoagulant used in PRP production.
METHODSThe microstructure change of platelets collected via heparin, citrate, acid citrate dextrose (ACD) and citrate-theophylline-adenosine-dipyridamole ( CTAD) was observed by TEM following time course. The extent of spontaneous activation of platelets in four groups was detected by measuring sP-selectin in plasma. The TGF-β1 release amount of activated PRP of four groups was measured.
RESULTSCTAD is superior to other anticoagulants in maintaining the integrity of platelet structures for a long time and preventing platelet spontaneous activation. ACD slightly surpassed heparin and citrate in above two aspects. ACD-PRP and CTAD-PRP released significantly more TGF-β1 compared with heparin and citrate.
CONCLUSIONSThe PRP quality and biological effects were strongly associated with the type of Anticoagulants. ACD and CTAD are optimal anticoagulants in PRP production for they can maintain platelet viability at a high level.

Objective To compare in-vitro percutaneous absorption and pharmacodynamic actions of anti-inflammation and inhibiting delayed-type hypersensitivity of Chinese herbal compound cremor for eczema (CHCCE) with different mass concentrations of synthetic borneol. Methods By adopting modified Franz diffusion device add with isolated BALB/cnude mice skin as a barrier, in vitro percutaneous absorption effectiveness of CHCCE with different mass concentrations of borneol was compared by in vitro percutaneous test after the content of matrine was determined with high performance liquid chromatography(HPLC). Meanwhile, the effects of CHCCE with different mass concentrations of synthetic borneol on reducing dimethylbenzene-induced auricular edema and suppressing delayed-type hypersensitivity induced by 2,4-dinitrochlorobenzene(DNCB) in mice were compared. Results Cumulative permeation amount of matrine in CHCCE with synthetic borneol was higher than that in CHCCE without synthetic borneol 2~ 48 h after administration (P < 0.05). There was no significant difference of cumulative permeation amount (P>0.05) among CHCCE groups with different mass concentrations of synthetic borneol after 48 h. In vitro percutaneous absorption behavior of matrine arrived to the steady state and the cumulative permeation amount of matrine presented a decreasing trend in all medication groups 12 h after administration. Within 12 h of the medication, the permeation rate of CHCCE with different mass concentrations of borneol was in the sequence of 3% borneol > 1% borneol > 2% borneol > 0.5% borneol > no borneol. The content of matrine was decreased with the increase of mass concentration of synthetic borneol after 12 h. The results of pharmacodynamic actions of CHCCE showed that compared with the blank control group, CHCCE with 1%, 3% synthetic borneol could significantly suppress the acute inflammation induced by dimethylbenzene and inhibit contact dermatitis induced by dinitrochlorobenzene (DNCB) in mice(P < 0.05). Compared with Triamcinolone Acetonide Acetate and Miconazole Nitrate and Neomycin Sulfate Cream, CHCCE with 1%, 3%synthetic borneol could decrease the serum level of IL-4, but the difference was insignificant(P>0.05). Conclusion CHCCE with 1% synthetic borneol has good effects on in vitro transdermal absorption, and can suppress inflammation and delayed-type hypersensitivity effectively.

Objective:This study was designed to explore the effects and mechanisms of raltitrexed on the growth of the human gastric cancer cell line (MGC-803) transplanted in nude mice. Methods: Models of MGC-803 xenograft transplanted in nude mice were established. Body weight, mental state, food, and stool of the nude mice were closely monitored, and the inhibitory action in the tu-mors was evaluated after drug intervention. Distribution and apoptosis of the tumor cells were examined through flow cytometric assay. P53 mRNA and protein expression levels were determined through reverse transcription-polymerase chain reaction and Western blot analysis. Changes among the three groups were compared. Results:Body weights and tumor volumes of the nude mice were lower in the raltitrexed and 5-fluorouracil (5-Fu) groups than those in the control group. Tumor inhibition ratios were 49.02%and 45.75%in the raltitrexed and 5-Fu groups, respectively. In the G0/G1 stage, the number of cells decreased in the raltitrexed and 5-Fu groups. Signifi-cant differences were found between the experimental and control groups (P<0.01). In the S stage, the number of cells increased in the raltitrexed and 5-Fu groups, with significant differences from the control group (P<0.01). P53 mRNA and protein expression levels in the raltitrexed and 5-Fu groups were significantly higher than those in the control group (P<0.01), but no significant differences were found between the raltitrexed and 5-Fu groups (P>0.05). Conclusion:Raltitrexed can inhibit the growth of MGC-803 xenograft trans-planted in nude mice and shows inhibitory effect similar to that of 5-Fu. Raltitrexed can induce the S-phase block of the cell cycle and cell apoptosis in the MGC-803 xenografts in the nude mice. This drug may exhibit an antitumor effect by upregulating the p53 mRNA and protein expression levels.

Objective To evaluate the early clinical outcomes of anterior cruciate ligament(ACL)reconstruction combined with anterolateral tenodesis procedure in patient with high grade pivot-shift after ACL injuries.Methods Among the 140 patients diagnosed as ACL injury and undergoing operations in our hospital between June and December 2015,18 presenting high grade pivot-shift 2+ or 3+ under anesthesia were included into this study.During their surgeries,the anterolateral tenodesis procedure using iliotibial tract ITB was applied together with ACL reconstruction.The anteroposterior stability of the knee was examined and pivot-shift test was conducted right after the operation as well as 6 and 12 months after that.The Lysholm score was used to evaluate the clinical function of their knees.Results The mean follow-up period of the 18 patients was 12.7 ± 2.4 months.There were 14 males and 4 females,with an average of 28.3 ± 7.1 years.No patients complained about unstable symptoms during the follow-up.The mean side-to-side difference of anteroposterior knee laxity assessed using KT1000 at 30 degree knee flexion was 2.3 ± 0.7 mm,which was significantly improved compared with preoperative assessment(9.2 ± 2.6 mm)(P<0.01).For the preoperative examination,the pivot-shift examination indicated 2+ in 13 patients and 3+ in 5 patients.However,all were negative right after the operation.Seventeen patients presented negative pivot-shift at the final follow-up,while 1 had 1+ rotational laxity.Significant differences were found in the Pivot-shift test before and after the operation.The average Lysholm score improved significantly from 67.7 ± 5.9(ranging from 55 to 78)before the operation to 89.0-± 4.6(ranging from 75 to 95)after that.Conclusion The high grade pivot-shift rotational instability could be effectively restored using the anterolateral tenodesis procedure,in addition to ACL reconstruction.The early stage clinical outcomes indicate significant improvement of the knee stability postoperatively.
