Background and purpose:Matrix metalloproteinase11(MMP-11)is an interesting member of the MMP family,and its overexpression has been demonstrated in human cancers such as non-small cell lung cancer and oesophageal adenocarcinoma.Furthermore,strong MMP11 gene expression is correlated with both increased aggressiveness of tumors and a poor clinical outcome,but there was no related reports on gastric cancer.We focussed our study on the significance of MMP-11 expression in gastric cancer.Methods:MMP-11 was selected and confirmed at both mRNA and protein level in 130 cases of gastric cancer serum specimen by RT-PCR,enzyme-linked-immuno-sorbent-assay(ELISA)techniques,respectively.Results:The total positive rates of serum MMP-11 mRNA in gastric cancer and healthy people were 68.4% and 5%,respectively.Our data demonstrated that MMP-11 protein levels in gastric cancer were(44?27)ng/ml,significantly higher than those in control subjects(P=0.001).MMP-11 protein levels in 30 cases with recurrence were(51?27)ng/ml and(27?28)ng/ml in 30 patients without recurrence.MMP-11mRNA positive expression was consistent with MMP-11 protein levels in gastric cancer patients.Conclusions:Serum MMP-11 may play an important role as a biomarker in diagnosis and prediction of recurrent gastric cancer.

Objective To analyze the clinical characteristics of systemic lupus erythematosus (SLE) patients with septic arthritis.Methods Twelve SLE patients with septic arthritis admitted to Peking Union Medical College Hospital from January 1990 to December 2012 were retrospectively analyzed.Results The median duration from onset of SLE to septic arthritis was 8.5 months (ranged from 1 to 120 months).All patients had received higher doses of steroid therapy (equal to prednisolone 1 mg ·kg-1 ·d-1) and immunosuppressant,and 5 of them had received methylprednisolone pulse therapy.The infectious manifestations included joint pain (all cases),swelling (5 cases),reduced joint function (8 cases) and fever (10 cases).All patients were oligo-arthritis.The hip and knee joints were most commonly involved.Three patients were infected by Salmonella,4 patients were infected by S.aureus,and 3 patients were infected by tuber culosis.Conclusion When SLE patients with long term steroid and immunosuppressant therapy developedacute joint pain and swelling,septic arthritis should be considered.Synovial fluid Gram stain,culture,blood culture and arthroscopy should be performed promptly.Appropriate antibiotics should be administered,and early treatment can improve the outcomes.

砄bjectives:To observe the difference of programmed cell death (PCD) and the expression of related gene p 53 in the development of normal palate and in the formation of cleft palate.Methods:The model of the development of cleft palat was estabished with retinoid acid (80 mg?kg 1 for each pregnant mouse). The palate samples were obtained at GD13 14 (at 13rd day 14 hours of prenancy),13 22 ,14 8,14 14 ,14 33 ,15 8,15 22 and 16 8 respectively.PCD was detected with TUNEL staining,while the mRNA transcription of p 53 was observed by in situ hybridization.Rssults:In early development of palate process,the positive index of PCD in the cleft palate samples was significantly higher than that in the normal ( P 0.05) between the two groups.Conclusion:The proliferation of mesenchymal cells of the early developmental palate process may be inhibited due to the abnomal PCD in the formation of cleft palate.The mechanism of PCD in this study may be a p 53 independed pathway.

Objective To observe the effect of electroacupuncture(EA) on the hippocampal expression of GluA1,pGluA1,CaMK Ⅱ and pCaMK Ⅱ in rats with vascular dementia(VD),so as to find out the underlying mo lecular mechanisms of EA in treating VD.Methods Thirty-two Wistar rats were randomly divided into a shamoperation group,a model group,a sham-acupuncture group,and an EA group (8 in each group).Permanent bilateral common carotid artery occlusion was performed to model vascular dementia in the model group,the shamacupuncture group and the EA group,while exposure but no occlusion of the bilateral common carotid were performed in the sham-operating group.Novel object recognition test was adopted to prove the establishment of VD rat model.All the rats were kept in an immobilization apparatus while receiving treatments.EA was applied ontoBaihui (GV20) and Zusanli (ST36) in EA group for 30 min,once daily for 7 days.Sham-acupuncture group were treated with needles inserted 0.5 mm superficially.And the sham-operation group and the model group were only immobilized.The protein expression of GluA1,pGluA1,CaMK Ⅱ and pCaMK Ⅱ in hippocampal tissue was detected by western blotting.Results The expression of GluA1 in the model group (1.216 ± 0.102) was significantly less than in the sham-operating group (1.918 ± 0.137) (P ＜ 0.05).The expression of GluA1 in the EA group (1.653 ± 0.169) was significantly higher than in the model group (1.216 ± 0.102) and in sham-acupuncture group (1.231 ±0.188) (P＜0.05).The expression of CaMKⅡ in the model group (1.516±0.392) was less than in the sham-operating group (2.187 ± 0.231) (P ＜ 0.05).The expression of CaMK Ⅱ in the EA group (2.733 ±0.387) was significantly higher than in the model group (1.516 ±0.392) and sham-acupuncture group (1.493 ±0.205) (P＜0.05).The expression ofpGluA1 in the model group (1.502 ±0.419) was less than in the sham-operating group (2.253 ± 0.244) (P ＜ 0.05).The expression of pGluA1 in the EA group (2.382 ± 0.308) was significantly higher than in the model group (1.502 ± 0.419) and the sham-acupuncture group (1.498 ± 0.223) (P ＜ 0.05).The expression of pCaMK Ⅱ in the model group (0.394 ± 0.227) was less than in the sham-operating group (0.667 ±0.175) (P＜0.05).The expression ofpCaMKⅡ in the EA group (1.189± 0.346) was significantly higher than in the model group (0.394 ± 0.227) and the sham-acupuncture group (0.408 ± 0.231) (P ＜ 0.05).Conclusion EA can enhance the protein expression and phosporylation of GluA1 and CaMK Ⅱ,causing silent synapses transforming into functional synapses,and consequently,long term potentiation was facilitated and cognitive impairment was improved by EA.

The abdominal visceral fat content in obese SD rats induced by high fat diet for 10 weeks was significantly higher than that in control group [(26±6 vs 13±3)g,P<0.01] ,along with increased CRP mRNA expression in abdominal visceral fat (0.901±0.085 vs O. 402±0.036, P<0.01). As compared with normal control group, in the high fat group the concentrations of CRP in portal vein [(743.8±95.8 vs 558.3 ±118.3) mg/L, P<0.01] and peripheral vein[(596.3±38.9 vs 485.8±30.2) mg/L,P<0. 05] were higher. The concentration of CRP in portal vein was significantly higher than that in peripheral vein in high fat diet group(P<0.01) ,but this was not evident in control group. These results suggest that the increased CRP expression in visceral adipose tissue may partially account for the elevation of serum CRP in obesity.

Objective To investigate whether functional electrical stimulation (FES) can improve the expression of proteins in the NMDAR1-pGLuR1 pathway so as to promote the recovery of motor function and sensation after stroke.Methods Eighty-one Wistar rats were used to make a photochemical brain model of local ischemia.Rats were randomly assigned into a sham, placebo stimulation or FES group.Rats in the placebo and FES groups had local ischemia induced in the M1 zone of the brain using the photosensitive dye Bengal rose.It was administered intravenously and a laser beam was then stereotactically positioned on the skull.The rats in the FES groups were stimulated for 30 minutes (10 minutes on, 10 minutes off, then 10 minutes on).The placebo group's treatment was similar, but without the electric current.The rats in the sham group received no intervention.The cylinder test and the adhesive-removal test were used to test the rats' motor function and sensation before the operation and before they were sacrificed.Cohorts were sacrificed after 3, 7 and 14 days of intervention.NMDA receptor and AMPA receptor were detected in the peri-ischemic cortex using western blotting.Results After 7 and 14 days the index of forelimb motor function in the cylinder test of the FES group was significantly better than that of the placebo group.The average adhesive-removal time of the FES group was also significantly faster compared with the placebo group.After 7 days the average expression of NMDAR1 in the FES group was significantly higher than in the placebo group.The average expression of GluR1 and pGluR1 in the FES group was significantly higher than in the placebo group after 14 days.Conclusion Functional electrical stimulation can improve motor function after ischemia through the NMDARAMPAR signal pathway, at least in rats.
