Objective To reveal the potential different longitudinal motion characteristics and differences of left and right muscular band (L-MB,R-MB)of interventricular septum (IVS) during systole and diastole in normal subjects.Methods Dual Doppler tissue imaging was applied for the longitudinal velocity curves of L-MB and R-MB of anterior and posterior interventricular septum(P-IVS,A-IVS) at basal,mid,and apical levels in eighty-two healthy subjects.Peak isovolumetric contraction (VIVC),systolic (Vs),early(Ve) and late (Va) diastolic velocities were measured,and myocardial velocity gradient(MVG)and Ve/Va ratio of each segment of L-MB and R-MB were calculated.Results ①Peak velocity of MB:the VrvC,Vs,Ve and Va of R-MB of both A-IVS and P-IVS were higher than those of L-MB; the VrvC,Vs,Ve and Va were gradually decreased from the base to apex of both A-IVS and P-IVS;the VIVC and Vs of A-IVS were higher than those of P-IVS; the Ve and Va of A-IVS were lower than those of P-IVS.②Correlation and MVG analyses of peak velocity of MB:the systolic and diastolic velocities between L-MB and R-MB of both A-IVS and P-IVS have shown a very strong positive correlation;the isovolumetric systolic MVG1 of L-MBof A-IVS,systolic MVG1 of R-MB of P-IVS and the diastolic MVG1 of both A-IVS and P-IVS were higher than those of MVG2.Conclusions The heterogeneity of longitudinal peak systolic and diastolic velocity and regional myocardial compliance,the consistency of moving direction and positive correlation of longitudinal peak systolic and diastolic velocity between L-MB and R-MB of both A-IVS and P-IVS have been demonstrated in normal subjects.

ObjectiveTo study the relationship between GDNF and ChAT Mrna and their potential role in the diabetic cognitive dysfunction by observing the change of the expression of GDNF and ChAT mRNA in brain under different blood glucose levels in STZ induced diabetic rats.MethodsForty male Wistar rats were randomly divided into diabetic group without blood glucose control( DM1 group),diabetic rats treated with insulin group( DM2 group),and normal control group( NC group).Blood glucose and body weight were detected every 4 weeks.Twelve weeks later,the hippocampus were submitted for cryostat sections which were subjected to the reverse transcription-polymerase chain reaction(RT-PCR) for GDNF and ChAT mRNA.ResultsThe expression of GDNF mRNA and ChAT mRNA in the hippocampus have negative correlation with HbAlc level( r =-0.962,-0.974,all P ＜ 0.001 );The GDNF expression had positive correlation with the ChAT mRNA expression( r =0.974,P ＜ 0.001 ).ConclusionLongterm chronic hyperglycation caused the “downregulation” of the GDNF expression in the hippocampal,which could cause the central cholinergic dysfunction symbled with the decrease of ChAT mRNA expression and the decline of learning and cognition ability.

Immune system is the autologous defense system for people to resist disease. Immunotherapy stimulates the immune system to resist disease, including treatment with immunocyte and vaccine. In recent years, the prognosis and survival quality of tumour patients have been greatly improved through cell immunotherapy by immunoregulation and killing directly on tumor. Immunotherapy becomes the hotspot in research.The study of DN Treg cell on immunotherapy will be of vital significance.

OBJECTIVE:To compare therapeutic efficacy and safety of dexamethasone with different administration routes in the treatment of chronic secretory otitis media. METHODS:A total of 150 patients with chronic secretory otitis media were random-ly divided into control group(75 cases)and observation group(75 cases). Control group was given Dexamethasone sodium phos-phate injection 5 mg by auripuncture under endoscope. Observation group was given Dexamethasone sodium phosphate injection 5 mg via eustachian tube under endoscope. Both groups were given relevant medicine every 2 days,for 3 times in total. Clinical effi-cacies of 2 groups were observed as well as bone conduction threshold under 1,2,4,8 kHz,the levels of water channel protein 1 and water channel protein 4,recurrence,the occurrence of tympanic cavity effusion before and after treatment. The occurrence of ADR was recorded. RESULTS:The total response rate of observation group(93.33%)was significantly higher than that of control group(80.00%);recurrence rate and the incidence of tympanic cavity effusion of observation group were significantly lower than those of control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in bone con-duction threshold,the levels of water channel protein 1 and water channel protein 4 between 2 groups(P>0.05). After treatment, the levels of bone conduction threshold in 2 groups were significantly lower than before;the observation group was significantly lower than the control group. The levels of water channel protein 1 and water channel protein 4 in 2 groups were significantly high-er than before;the observation group was significantly higher than control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:The administration of dexa-methasone via eustachian tube under endoscope is significantly better than auripuncture in terms of therapeutic efficacy for chronic secretory otitis media,relieving clinical symptom,improving bone conduction threshold,up-regulating water channel protein level, reducing the risk of recurrence and tympanic cavity effusion. The two routes of adimistration have similar safety.

Objective To investigate the effect of tirofiban hydrochloride in the treatment of coronary heart disease and its influence on homocysteine level.Methods 92 patients with coronary heart disease were selected as research subjects.They were randomly divided into the observation group and the control group,46 cases in each group.The control group was treated with anti-thrombotic,nitrates and other conventional western medicine.The observation group was treated with tirofiban hydrochloride based on the conventional treatment.Results The total effective rate of the observation group was 95.65%,which was higher than 82.61% of the control group,the difference was significant (χ2=4.039,P<0.05).And the homocysteine level in the observation group was (5.38±1.02)μmol/L,which was lower than (7.27±1.19)μmol/L in the control group,the difference was statistically significant (t=8.179,P<0.01).After treatment,the cardiac function CO level[(4.96±0.98)L/min],EF level[(62.48±11.16)%]and SV level[(86.37±11.47)mL]in the observation group were higher than those in the control group,the differences were statistically significant (t=2.271,2.954,2.911,all P<0.05).After treatment,the hs-CRP level[(4.25±1.32)mg/L]and Fib level[(3.14±0.73)g/L] in the observation group were lower than those in the control group,the differences were statistically significant (t=7.981,3.174,all P<0.01).ConclusionTirofiban hydrochloride in the treatment of coronary heart disease can effectively contribute to the reduction of homocysteine levels and alleviate atherosclerosis lesion progression,not only can reduce severity of myocardial ischemia and fibrinogen and high-sensitivity C-reactive protein levels,but also can reduce the thrombosis and inflammation produced by the degree of harm to the patients.
