Regulatory T cells (Tregs) possess the function of immune suppression and achieve immunosuppression by the approach of expressing cytotoxic T lymphocyte-associated antigen,perforin-particle enzyme mediated cytotoxic effect,and secretion of cytokines such as IL-10,TGF-β,et al.The antibodies,vaccines and chemical drugs can be applied for targeting FOXP3 + CD25 + CD4 + Tregs,depleting Tregs in peripheral blood and tumor tissues of patients of various forms of cancers.The function of immune suppression can be decreased and antitumor curative effects by immunotherapy can be enhanced.

Aim To develop a modified model of subarachnoid hemorrhage in rats. Motheds The SAH model was induced by injecting autologous blood into the cisterna magna without exposing the occipitoaxial ligament.The main modified point was a hole bored by a dental drill at the middle point of the boundary between the parietal bone and the occipital bone,then a catheter was inserted 8 mm to cisterna magna and the autologous blood was injected . Hemorrheological parameters were measured after the model was created.The intrinsic oversxidase method was used to show the microvessel of CA_1 region. The diameter, density ,and the aera of microvessel were measured and ananlyzed by Image-Pro Plus image analysis system. Results The total blood viscosity(?b) and erythroagglutation index(AL) in SAH model group increased significantly,however,the microvesse area and microvesse density in SAH model group decreased obviously. Conclusion The modified model of subarachnoid hemorrhage in rats is reliable and easy to operate on.

AIM:To compare the curative effect of conjoint fascial sheath suspension and the simple frontalis muscle suspension for moderate or severe ptosis.METHODS:In March 2013 to March 2016 in our hospital, 46 patients with moderately severe ptosis(68 eyes) were taken as the research objects.According to random number table method, they were divided into study group and the control group, 23 cases in each group.Study group(34 eyes) received the joint fascial sheath suspension (CFS), the control group(34 eyes) received frontalis muscle suspension.The degree of ptosis correction, upper eyelid retracted, satisfaction and complications of two groups were compared.RESULTS:The corrected rate of the treatment group was higher than that of the control group, the difference was statistically significant (P<0.05).After treatment, the upper eyelid retracted of the study group was significantly lower than that of the control group, the difference was statistically significant (P<0.05).The satisfaction of the treatment group was higher than that of the control group, the difference was statistically significant (P<0.05).The incidence of complications in the study group was significantly less than that in the control group, and the difference was statistically significant (P<0.05).CONCLUSION:Conjoint fascial sheath suspension is more effective on the treatment of severe ptosis than the simple frontalis muscle suspension, and has advantages such as less trauma, repeatable, and less complication.

Objective To evaluate the relationship between extracelluar signal?regulated protein kinase 1∕2 (ERK1∕2) and signal transducer and activator of transcription 3 (STAT3) signaling pathways involving in cardioprotection induced by diazoxide postconditioning in rats. Methods Sixty adult male Sprague?Dawley rats, aged 3 months, weighing 240-260 g, were randomly divided into 5 groups ( n=12 each) using a random number table: sham operation group ( SH group ) , ischemia?reperfusion ( I∕R ) group, diazoxide postconditioning group ( D group ) , ERK1∕2 inhibitor U0126 group ( U group ) , and STAT3 inhibitor Stattic group ( St group) . Myocardial I∕R was produced by occlusion of anterior descending branch of the coronary artery followed by 120 min reperfusionIn I∕R and D groups, 0?4% dimethyl sulfoxide 1 ml and 7 mg∕kg diazoxide ( in 1 ml of 0?4% dimethyl sulfoxide) was injected through the femoral vein at the onset of reperfusionIn U and St groups, U0126 100 μg∕kg and Stattic 500 μg∕kg were injected through the femoral vein at 10 min before reperfusion, and the other procedures were similar to those previously described in group DAt 120 min of reperfusion, the rats were sacrificed, and myocardial specimens were obtained from the left ventricle for determination of myocardial infarct size, cell apoptosis, and ERK1, ERK2 and STAT3 mRNA expression ( real?time PCR), and phosphorylated ERK1∕2 ( p?ERK1∕2) and phosphorylated STAT3 (p?STAT3) (using Western blot). Apoptosis index (AI) was calculated. Results Compared with group S, the myocardial infarct size and AI were significantly increased, and the expression of ERK1, ERK2 and STAT3 mRNA, p?ERK1∕2 and p?STAT3 was down?regulated in group I∕R. Compared with group I∕R, the myocardial infarct size and AI were significantly decreased, and the expression of ERK1, ERK2 and STAT3 mRNA, p?ERK1∕2 and p?STAT3 was up?regulated in group D. Compared with group D, the myocardial infarct size and AI were significantly increased in U and S groups, the expression of ERK1, ERK2 and STAT3 mRNA, p?ERK1∕2 and p?STAT3 was down?regulated in group U, and the expression of STAT3 mRNA and p?STAT3 was down?regulated, and no significant change was found in ERK1 and ERK2 mRNA and p?ERK1∕2 expression in group S. Conclusion STAT3 signaling pathway is located downstream of ERK1∕2 signaling pathway in the mechanism by which diazoxide postconditioning reduces myocardial I∕R injury in rats.

Objective To evaluate the role of ERK1/2 signaling pathway in mitigation of myocardial ischemia-reperfusion (I/R) injury by diazoxide postconditioriing in rats.Methods Sixty adult male SpragueDawley rats,aged 3 months,weighing 240-260 g,were randomly divided into 5 groups (n =12 each) using a random number table:sham operation group (S group),I/R group,vehicle group (Ⅴ group),diazoxide postconditioning group (D group),and ERK1/2 signaling pathway inhibitor U0126 group (U group).Myocardial I/R was produced by occlusion of left anterior descending branch of coronary artery for 30 min followed by 120 min reperfusion.In V and D groups,0.4％ DMSO and diazoxide 7 mg/kg (in 1 ml 0.4％ DMSO) were administrated,respectively,through the femoral vein at the onset of the reperfusion.In U group,U0126 was given through the femoral vein at 10 min before reperfusion,and the following procedures were similar to those previously described in group D.At 120 min of reperfusion,myocardial specimens were obtained for detection of myocardial infarct size,cell apoptosis (using TUNEL),and expression of ERK1/2 mRNA (by RT-PCR),total ERK1/2 (t-ERK1/2) and phosphorylated ERK1/2 (p-ERK1/2) (by Western blot).Apoptosis index was calculated.Results Compared with S group the myocardial infarct size and apoptosis index were significantly increased in the other groups,the expression of ERK1/2 mRNA and p-ERK1/2 was down-regulated in I/R,V and U groups,and no significant change was found in the expression of ERK1/2 mRNA and p-ERK1/2 in Dgroup.Compared with I/R group,the myocardial infarct size and apoptosis index we re significantly decrcaed,and the expression of ERK1/2 mRNA and p-ERK1/2 was up-regulated in D group,and no significant change was foundin the parameters mentioned above in V and U groups.Compared with D group,the myocardial infarct sizeand apoptosis index were significantly increased,and the expression of ERK1/2 mRNA and p-ERK1/2 was down-regulated in U group.There was no significant difference in t-ERK1/2 expression between five groups.Conclusion Diazoxide postconditioning mitigates myocardial I/R injury possibility through activating ERK1/2 signaling pathway in rats.

Objective To investigate the changes in cerebral oxygen metabolism during liver transplantation in patients with liver cirrhoses.Methods Sixteen ASAⅢorⅣpatients with liver cirrhoses(14 male,2 female)aged 25-67 yrs,weighing 45-80 kg undergoing liver transplantation were studied.Radial artery was cannulated for direct BP monitoring and blood sampling.Swan-Ganz catheter was placed in pulmonary artery (PA)via right internal jugular vein(IJV)for cardiac output(CO)monitoring and sampling mixed venous blood. Left IJV was cannulated and the catheter was advanced cephalad until jugular bulb for blood sampling.Anesthesia was induced with midazolam,fentanyl,propefol and vecuronium and maintained with isoflurane inhalation and intermittentⅣboluses of fentanyl and vecuronium.The patients were mechanically ventilated after tracheal intubation.PaCO_2 was maintained between 30-45 mm Hg.Blood samples were taken from radial artery,pulmonary artery and jugular bulb simultaneously for blood gas analysis before operation(T_0,baseline),10 min before anhepatic phase(T_1)20 min after onset of anhepatic phase(T_2),30 min after graft reperfusion(T_3)and at the end of operation(T_4).Oxygen delivery(DO_2),oxygen consumption(VO_2),oxygen content of jugular bulb blood (CjvO_2),cerebral arterial-venous oxygen content differences(Ca-jvO_2)cerebral oxygen extraction ratio(CERO_2) and CBF/CMRO_2 were calculated.Results The mean duration of operation was(364?51)min and the mean intraoperative blood loss was(1340?430)ml.CO was significantly increased before anhepatic phase(T_1), during neohepatic phase(T_3)and at the end of operation(T_4)but decreased during anhepatc phase(T_2)as compared with the baseline value at T_0.Hb,CaO_2,Ca-jvO_2 and CERO_2 were all decreased while SjvO_2 and CBF/ CMRO_2 were increased during operation;DO_2,VO_2 and CjvO_2 were decreased during anhepatic phase;DO_2 was increased during other phases;VO_2 was increased at the end of operation as compared with the baseline(T_0)(P＜0.05 or 0.01).Conclusion There is no cerebral oxygen deficiency during liver transplantation in patients with liver cirrhoses.

It is to observe the therapeutic action of Guizhi Fuling capsule and the combination of active ingredients on model rats with uterine leiomyoma. The hysteromyoma rats models was established in rats by loading eatrogen, to observe the effect on pathological condition of uterus, uterus wet weight, the content of estradiol and progesterone. Guizhi Fuling capsule and the combination of active ingredients remarkably decreased uterus weight, restrained the excess proliferation of the smooth muscle of uterus, decreased the estraiol and progesterone in blood serum. Guizhi Fuling capsule and the combination of active ingredients can restrain the formation of hysteromyoma in a dose-dependent manner. Perhaps the combination of active ingredients is the material foundation of antihysteromyoma.
