OBJECTIVE:To investigate the effects of Tongxinluo capsules on the levels of serum cyclophilin A (CyPA) and matrix metalloproteinase-9 (MMP-9) in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI).METHODS:A total of 115 CHD patients undergoing PCI were randomly divided into control group (59 cases) and observation group (56 cases).Control group was given conventional treatment.Observation group was additionally given Tongxinluo capsules 0.78 g,3 times a day,for consecutive 6 months,on the basis of control group.The levels of CyPA and MMP-9 as well as the occurrence of ADR were observed in 2 groups before and after treatment.RESULTS:Before treatment,there was no statistical significance in serum level of CyPA and MMP-9 between 2 groups (P＞0.05).The levels of CyPA in 2 groups 1 d and 1 month after surgery as well as the level of CyPA in control group 6 months after surgery were all significantly higher than before surgery,but the observation group was significantly lower than the control group 1 and 6 months,this index was decreased gradually as time,with statistical significance (P＜0.05).There was no statistical significance in the levels of CyPA between 2 groups 1 d after surgery or in observation group between 6 months after surgery and before surgery (P＞0.05).The levels of MMP-9 in 2 groups 1 d and 1 month after surgery were significantly higher than before surgery,and the observation group was significantly lower than the control group,this index was decreased gradually as time,with statistical significance (P＜0.05).There was no statistical significance in the levels of MMP-9 of 2 groups between 6 months after surgery and before surgery(P＞0.05).There was no statistical significance in the incidence of ADR between 2 groups (P＞0.05).CONCLUSIONS:Based on routine treatment,Tongxinluo capsules can significantly reduce the levels of CyPA and MMP-9 in CHD patients after PCI.

Anxiety and depression are common conditions among patients with irritable bowel syndrome(IBS)which may induce or aggravate intestinal symptoms. Psychological factors are considered to be involved in the pathogenesis of IBS via both central and peripheral pathways,and functional magnetic resonance imaging(fMRI)revealed that several brain areas,such as anterior cingulate cortex and prefrontal cortex,are associated with IBS,anxiety and depression. This article reviewed the use of fMRI for studying the correlation of IBS brain activity with anxiety and depression and its role in the central pathogenesis of IBS.

Objective To establish the murine congenital infection model by MCMV and observe the pathological changes and infection status of brain tissue.Methods After anesthesia,mice who were pregnant 11-13.5 days (E11-13.5 d) were intra-amniotic injected one uterus by one with virus (MCMV K181 suspension,1 μl,1×103 PFU).The control group of the same period was intra-anmiotic injected with culture medium DMEM (1 μl).Carefully reset the uteruses and close the abdomen.After 5 days of separated feeding,kill the pregnant mice,take the fetus out of the uterus,anesthetize and kill them.Make frozen sections of these fetal brains.Some sections were stained using conventional HE method,to observe the pathological changes under the light microscope.Detect MCMV early antigen in the brain tissue by immunohistochemistry staining and immunofluorescence assay.Results The survival rates of the infected group were 71.9％.Compared with the control group,intra-amniotic inoculation of MCMV does not affect the rate of fetal survival,fetal absorption,fetal death and the average weight of the heads,but decrease their average weight of the bodies.The pathological changes are found in the brain tissue of the mouse in the infection group.Through enzyme immunohistochemistry assay,there are many MCMV infected cells in brain-ventricular zone,brain subependymal zone,cerebral cortex and hippocampus area in the infection group.Similar findings were observed by immunofluorescence method.Conclusion By intra-amniotic injection of MCMV suspension,murine model of MCMV congenital infection can be successfully established.This model could be used to study the mechanisms of encephalodysplasia caused by congenital CMV infection in vivo.

Objective To explore the effects of murinecytomegalovirus(MCMV)infected mouse embryonic fibroblasts(MEF)on the proliferation and activation of regulatory T cell in vitro. Methods A co-culture system of T cell and MCMV infected MEF(T-MEF MCMV)was established.The viral load of supernatant was determined by plaque assay.The proliferation of T cells was observed with cell counting.The proportion of CD4+ CD25+ cells was measured by flow cytometry.The levels of Foxp3 protein were measured by Western blot.Reverse transcription polymerase chain reaction(RT-PCR)assay was utilized tO determine whether MCMV infection of MEF influenced the level of transforming growth factor(TGF)-β mRNA.The level of TGF-β protein in supernatant was measured by double-antibody sandwich enzyme linked immunosorbent assay(ELISA).The difference between T-MEF MCMV group and control group was assessed by one-way ANOVA.Results When T cells were co-cultured with MCMV infected MEF for 1 day and 3 days,the viral load in supernatant decreased.But when co-culture lasted for 6 days,the antiviral effect obviously diminished,as the viral load[(5.58±0.67)×105 PFU/mL]of the experimental group showed no statistic difference with MEF MCMV control group[(6.05±0.34)×105PFU/mL].When co-cultured with MCMV infected MEF for 3 days,T cell increased from pre-culture level of[(2.02±0.05)×106/mL]to(2.25± 0.13)×106/mL(P＜0.05).But when co-culture lasted for 6 days,the number of T eelI returned to (2.08±0.14)×106/mL,which had no statistic difference with that of co-culture for 3 days system. Both the expressions of Foxp3 protein and the proportion of CD4+ CD25+ Foxp3+ Treg cells in T-MEF MCMV group were up-regulated as the infection time extended,which were two times and three times of the control group level,respectively.The mRNA level(A value)of TGF-β in MCMV infected MEF increased from baseline of 1.09±0.13 to 3.15±0.54 on day 3 after infection.The expression of TGF-β in supernatant 3 days after infection was(3.85±0.32) μg/L,which was significantly higher than that before infection[(1.74±0.14)μg/L,P＜0.05].Conclusions Activated T cells have antiviral effect.However,the function of T cells is rapidly inhibited after activation,which may be due to the expression of Foxp3 mRNA induced by MCMV infected MEF and increased CD4+ CD25+ Treg proportion of the co-cultured T cells.TGF-β level is significantly increased after CMV infection,which may be an important mechanism of Treg proliferation.MCMV may manipulate Treg to evade specific immune elimination and,as a result,to cause CMV replication.

Objective To develop a sheet to assess infection risks in children with malignant tumors after chemotherapies.Methods A risk assessing sheet (to consult) was designed and used to consult 24 experts from 9 hospitals located in 6 provinces.After 3 rounds of expert consultation,a sheet (to try) was developed and tried by nurses in the clinic.And then a sheet (to use) was developed.Results The authority coefficient of experts was 0.79,the positive coefficient of experts was 1.00 and 0.96.The sheet (to try) developed after 3 rounds of expert consultation consisted of 30 items and was divided into 2 parts,one was about static items and the other was about dynamic items.Depending on the trying of the sheet (to try),the sheet (to use) was constituted by 8 fundamental immune state assessing items and 16 infection risk screening items.Conclusions Experts consulted in the study were quite reliable,representative and positive.The sheet (to use) seemed to have good pertinence and practicability.Further studies should be done to verify whether the sheet (to use) may help nurses to prevent children with malignant tumors from infections after chemotherapies.
