Objective To study the effects of phycocyanin on the expressions of matrix metalloproteinase 2 and 9(MMP-2 and MMP-9) after focal cerebral ischemic reperfusion in rats.Methods A rat middle cerebral artery occlusion/reperfusion(MCAO/R) model was built up using the intraluminal filament method and treated by phycocyanin.The brain water content(BWC) was calculated with dry-wet method and the Evans blue(EB) of the brain was measured with the method of colorimetry.The expressions of MMP-2 and MMP-9 were determined by immunohistochemical assay.Results The BWC and EB of the brain increased after cerebral ischemic reperfusion and peaked at reperfusion 2d,and decreased after applying phycocyanin.In control group,the upregulation of MMP-2 began at ischemic reperfusion 24h,reached a maximum at 3～7d,then subsided gradually,but was still in high level at 14d.In phycocyanin group,the expressing time-phase pattern of MMP-2 was similar to and significantly lower than that in control group at same time.In control group,the upregulation of MMP-9 began at ischemic reperfusion 6h,increased at 12h and reached a maximum at 2d,then subsided gradually at 3d to sham group level at 14d.In the phycocyanin group,the expression of MMP-9 was significantly lower than that in control group,and the time-phase pattern of MMP-9 was similar to that in control group.Conclusions Phycocyanin might play an neuroprotective effect by down regulating the expressions of MMP-2 and MMP-9 to reduce brain edema after cerebral ischemic reperfusion.

Objective To compare the analgesic effects of fire needling, conventional acupuncture and acupoint catgut embedding in rats with rheumatoid arthritis.Methods Fifty healthy male SD rats were randomized into control, model, acupuncture, fire needling and catgut embedding groups, 10 rats each. A SD rat model of rheumatoid arthritis was made by intracutaneous injection of complete Freund’s adjuvant into the right hind foot pad. Right Kunlun and Zusanli were selected as therapeutic points in the three groups and given fire needling, acupuncture or catgut embedding. The right paw mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were used as observation indices and measured in every group of rats at one day before and four days after model making and at one, seven and fourteen days after the beginning of treatment. Rat paw inflammatory tissues were separated after the completion of treatment. The IL-1 and TNF-α contents of them were measured. Results There were statistically significant differences in MWT and TWL between the model, acupuncture, fire needling or catgut embedding group and the control group after model making, and one, seven and fourteen days of treatment (P<0.01). There were statistically significant differences in MWT and TWL between the fire needling group and the model, acupuncture or catgut embedding group after one, seven and fourteen days of treatment (P<0.01,P<0.05). There was a statistically significant difference in MWT between the acupuncture or catgut embedding group and the model group after one, seven and fourteen days of treatment (P<0.01). There was a statistically significant difference in TWL between the acupuncture or catgut embedding group and the model group after seven and fourteen days of treatment (P<0.01,P<0.05). There were statistically significant differences in IL-1 and TNF-α contents between the model, acupuncture, catgut embedding or fire needling group and the control group after model making (P<0.01). after treatment, there were statistically significant differences in IL-1 and TNF-α contents between the acupuncture, catgut embedding or fire needling group and the model group and between the acupuncture or catgut embedding group and the fire needling group (P<0.05).Conclusions Fire needling can raise pain threshold in rats with rheumatoid arthritis. It alleviates rheumatoid arthritis-induced chronic pain by reducing the inflammatory factor content of affected muscular tissues.

Objective To investegate the effect of ginsenoside Rg1 on the apoptosis related protein FLICE-inhibitory protein(FLIP),Fas-associated death domain protein (FADD)and Caspase-3 in the subatania nigra(SN)of 1-methyl-4-phenyl-1,2,3,6-tetrahyd-ropyridine (MPTP)-induced mouse models of Parkinson’s disease(PD), and to investigate the role of FADD and FLIP in the pathogenesis of PD and the protective effect of ginsenosides Rg1 on dopaminergic neurons.Methods 45 C57BL/6N mice were randomly divided into control group,model group and ginsenoside Rg1 group (n=15).The mice in model group were injected with MPTP by intraperitoneal,the mice in Rg1 group were injected with ginsenoside Rg1 before injecting MPTP,and the mice in control group were injected with normal saline by intraperitoneal. The behavioral changes of the mice in various groups were observed, and immunohistochemistry and Western blotting methods were used to observe the expressions of tyrosine hydroxylase (TH),FADD,FLIP and Caspase-3 in substantia nigra of the mice.Results Compared with control group,the mice in model group presented with typical symptoms of PD, the TH-positive neurons in the subatania nigra was significantly reduced (P<0.01 ), the number of FADD, FLIP and Caspase-3 positive cells was significantly increased(P<0.01),and the cytoplasm was deeply stained;the protein expression levels of FADD,FLIP and Caspase-3 were significantly increased (P<0.01).Compared with model group,the PD symptoms of the mice in ginsenoside Rg1 group reduced, the number of TH-positive neurons was significantly increased, the number of positive cells of FLIP,FADD and Caspase-3 were significantly reduced(P<0.01),and the cytoplasm was lightly stained;the protein expression levels of FADD, FLIP and Caspase-3 were significantly reduced (P<0.01 ). Nonlinear correlation analysis found that there was a positive relationship between the number of FADD and Caspase-3 positive cells (r=0.791,P<0.05).Conclusion Ginsenoside Rg1 may play a neural protective effect dopaminergic on neurons by modulating the FADD and FLIP expressions in SN of PD model mice.

Objective To investigate the status and influencing factors of infusion-related adverse events in third-party cord blood stem cell infusion. Methods A total of 305 patients successfully underwent haploidentical stem cell transplantation combined with the third-party cord blood(CB) infusion,were recruited by convenience sampling from January 2013 to December 2015,in hematological department of a tertiary hospital in Suzhou. A self-developed questionnaire and adverse event assessment scale were used to investigate the influencing factors. Results The rate of infusion-related adverse events was 49.51%,81.82% were related to cardiovascular adverse events with the high-est rate of hypertension(76.14%). Logistic regression analysis showed that age(OR=1.030,95CI%:1.010-1.051),HLA matching between CB and receptor (OR=0.589,95%CI:0.413-0.838),thawed CB cell activity (OR=1.064,95%CI:1.015-1.115)were major influencing factors. Conclusion Nurses should pay attention to patients who are elderly,with low matching HLA and receive thawed CB product with high cell activities,and provide timely nursing care in advance.
