AimTo explore the kinetic change of the IgG,T-cell subsets and IL-2 level from the mice infected with T. Spiralis. Methods The level of specific IgG A band IL-2 was determined by ELISA,the percentage of CD4+and CD8+ T-cells were examined by flow cytometry on 7, 14,21,28,35 days after mice infected with T. spiralis respectively. ResultAfter infected with T. spiralis,the level of IgG in mice rised gradually,and reached its peak on the 35th day. The change of T-cell subsets showed that CD4+T cells decreased,which CD8+Tcells increased. The ration of CD4+/CD8+cells decreased,and which was the obvious on the 14thday. It did not recover to normal level even on the 35th day. The IL-2 of level reached the peak on the 7th day after infected,then IL-2 level decreased quickly and lower than that of normal mice on 35th day after infected. Conclusion When the acute phase of T. spiralis infection,the immune function of host was inhibited. The protective immunity of against T. spiralis infection was cellular immunity mainly ,in cooperation with humoral immunity.

Objective To explore the change and its clinical significance of neuron-specific enolase (NSE) and S-100? in serum and hippocampus tissue in rats with epilepsy induced by Kainic acid (KA).Methods 180 Wistar rats were randomly classified into control, KA and carbamazepine (CBZ) group, and the later two groups were further divided into 6 sub-groups (1 h, 4 h, 12 h, 24 h, 48 h and 72 h ) according to epileptic attack at different time point. The NSE and S-100? concentrations in serum and homogenate of hippocampus were determined by radioimmunity assay (RIA) and enzyme linked immunosorbent assay (ELISA), respectively.Results The concentrations of NSE and S-100? were dynamic change during 72 h after epileptic attack in serum and hippocampus homogenate, and the changes were synchronous. The concentrations reached peak at 12 h. Both NSE and S-100? concentrations in KA and CBZ group were obviously higher than those in control group ( P

Objective To assess the reliability of the modified lateral transgluteal approach (modified Bauer approach) to the hip for the joint prosthesis.Method The Bauer approach modification was used for 43 hip endoprosthetic replacement.Results The modified approach provided good exposure of the hip for arthroplasty, and early chance of function recovery.Excellent and good rate was 96.97% according to Harris result evaluation. No evidence of weakness of abductors of the hip and damage to superior glouteal nerve was found at six months.Conclusion The modified Bauer approach is reliable and recommendable for primary hip replacement because of its good exposure of the hip and the least disturbance to the abductor function.

Objective To introduce a new method for correcting square face deformity.Methods This operation consists of malar reduction (MR)and mandibular angle osteotomy (MAO),which could be done simutaneously or at different time.Results A total of 21 patients with square face deformity accepted MR and MAO in which 12 cases were done simutaneously and 9 cases at different time.After this procedure, the width of the mid face and the lower face reduced by 15.3?3.2mm and 14.2?2.5mm, respectively. A11 the cases achieved satisfactory results without complications.Conclusion This method can effectively correct square face deformity by reducing the width and protrusion of the mid face and the width of the lower face.

The cultivation of communication skill of anesthesiology medical students has already become a request as time developing.Not only it accommodates the request of medical model and society development to cultivate the communication skill of anesthesiology medical students from the aspect of strengthening their self-confidence and pride,global consciousness and international view,catholicity and humanity as well as cognitive ability,but also embodies the requirement of anesthesiology anthropo-culture.So there should be pertinent measures to cultivate the communication skill of anesthesiology medical students.

Objective To study the immune response induced by the mice immunized with Trichinella spiralis(T.spiralis) adult worm soluble antigen(AWSAg). Methods T.spiralis AWSAg was prepared to immunize Kunming strain mice. Dynamic changes of IgG, IL 2 and T lymphocyte subsets from immunized mice were determined after challenge infection on d 7, d 14 , d 21 , d 28 and d 35 . Results On d 7 after challenge infection, IgG and CD4 + T cells of immunized group were markedly elevated and persisted higher over the observation period. In contrast, CD4 + T cells and CD4/CD8 ratio were significantly decreased in unimmunized group resulted from immune suppression after infection. IL 2 levels reached the peak on d 7 and persisted in high level from d 7-d 21 in both immunized and unimmunized group after infection, then decreased gradually. Till 35 days after infection, IL 2 level was still higher than the normal mice. Conclusion Mice immunized with AWSAg of T. spiralis produced a potential cellular and humoral immune response.

Objective To evaluate the effects of endothelial nitric oxide synthase (eNOS) gene transfer on intrahepatic vascular resistance (IHVR) and portal venous pressure (PVP) in cirrhotic rats. Methods (1) 5 days after eNOS gene transfer, the in situ liver perfusion system (ISLP) was prepared and in different groups of controls and eNOS treated rats, the followings were analyzed: portal perfusion pressure (PP) dose-response curve to norepinephrine (NE); the effects on PP caused by specific nitric oxide synthase (NOS) inhibitor N-monomethyl-L- arginine (L-NMMA) or the nitric oxide (NO) synthesis substrate L-arginine (L-Arg). (2) The experiment of perfusion via portal vein in vivo was performed and the effects of L-NMMA on the PVP was observed. Results (1) In ISLP model, after L-NMMA was added into the perfusate of the control rats, PP dose-respose to NE increased remarkably and the peak of PP increased to (26.7?0.9) mm?Hg. The increased PP response to NE caused by L-NMMA was offsetted by L-Arg and the peak of PP decreased to (23.2?0.9) mm?Hg. In eNOS treated rats, PP response to NE was significantly lower than that in controls (P

The effect of hydrazine on blue membrane was investigated by the UV/VIS absorption spectrum technique and the flash photolysis technique, the results show that: hydrazine can convert blue membrane to purple membrane and the photocycle returns, but the rate of decay of photcycle intermediate(M412) quickens, this phenomenon is not seen when metal cations are added to blue omembrane solution(the rate of decay of photcycle intermediate slowers). At the same time , the effect of pH and temperature on the interaction between hydrazine and blue membrane was investigated. When hydrazine was added to blue membrane solution, the sensitivity of the reaction is pH and temperature dependent. Over the pH range(2~4.8), the sensitivity of the reaction lowers with the increase of the acidity. Over the temperature range(20~40℃), the sensitivity of the reaction lowers with the increase of the temperature.
