Acid a-naphthyl acetate esterase (ANAE), a cytoplasmic marker was used to identify the T lymphocytes and their subpopulations in peripheral blood of mice experimemally infected with T. spiralis. The results showed that the absolute number of lymphocytes and T lymphocytes increased in parallel on d, after infection, reachiug the peak on d14, and remaining above normal level on d60. The spotted granular ANAE positive cells (Helper T cells, Th) were decreasing and the scattered granular ANAE positive cells (suppressor T cells, Ts) were increasing, leading to a lowering of the Th/Ts ratio which was most marked on d14 and returned to normal on d60. The depres-sion of host immune function during T. spiralis infection might be related to the lowering of Th/Ts ratio.

Trauma and infection may cause a stress reaction to the body,which leads to the metabolic imbalance of organs and tissues,but some treatment methods can effectively reduce the negative effects of undesirable stress on body metabolism.This article focuses on the effects of trauma and infection stress on the protein metabolism,furthermore,introduces some related treatment methods.

Objective To study whether the HBC-A2/scFv fusion protein mediates killing of tumor cells by viral specific cytotoxic T cells. Methods The fusion protein was attached to the CD71-expressing, HLA class Ⅰ negative tumor cells. And then, cytolysis by viral peptide-specific CTLs which were generated by co-culture of peripheral blood lymphocytes from HLA-A2 positive donors with inactivated T2 cells pulsed with the viral peptide were tested by lactate dehydrogenase (LDH) releasing. Results The fusion protein can attach the active viral peptide/HLA-A2 complex to K562, HepG2 and U937 cells through binding of CD71 scFv to CD71 (37.30% ±8.25%, 27.20% ±3.88%, 21.80% ±6.49% ) and mediate cytotoxicity of viral peptide-specific CTLs against those cells in vitro ( K562: 42.08% ± 1.14% vs 8.07%± 1.39%; HepG2: 49.72% ± 1.59% vs 12.46% ± 1.26%; U937: 39.72% ± 3.26% vs 7.13% ±1.48% ). Conclusion This viral peptide/HLA-A2 complex targeted by CD71 scFv is able to redirect viral peptide-specific T-cell mediated immune responses against tumor cells.

Objective To explore the effect of isometric contraction-induced ischemic burden for evoking maximal intrinsic femoral artery collateral circulation. Methods Twenty-four adult New Zealand rabbits weighing (2.0±0.5) kg were subjected to a model of isometric contraction-induced ischemia. An electrode was implanted in the sciatic nerve of the left hind limb for evoking isometric contraction of the gastrocnemius, which blocked local blood flow and induced local ischemia. Femoral artery collateral blood flow (FCBF) was measured using a micro-sphere technique. Results Local blood flow was the lowest at 40% of the maximal isometric contraction (IEmax), and reached plateau at 60% of IEmax. FCBF increased gradually and reached a plateau at 40% of IEmax in the 4th min. After 4 minutes at 40% of IEmax, FCBF had increased to higher than pre-stimulus, peaking in the 2nd minute, and then decreasing gradually to baseline at the 5th minute after reperfusion. It ceased to increase when reperfusion was prolonged to 8 or 10 min. Conclusions The minimal ischemic burden for full obstruction of the femoral artery is 40% of IEmax, and the shortest stimulus duration is 4 min. The maximal FCBF opening duration is no more than 5 min.

Interleukin 33 (IL 33),one member of the IL-1 family,is expressed in many types' tissue and regulation of multiple target cells via its suppression of tumorigenicity 2 (ST2) receptor.Therefore,the crucial roles of the novel cytokine IL-33 in allergic,endocrine diseases,infectious diseases and cancer are becoming characterized.The function of IL-33 in different parasite infection is distinctive in parasitic infections,due to the difference in pathogenic mechanism and in the time course of IL-33 expression.

Objective To study the protective effect of minocycline against ischemia-reperfusion injury after liver transplantation and its molecular mechanism after circulatory death in rats.Methods The rat donation after circulatory death (DCD) liver transplantation model was established by using magnetic-ring method.The donor and recipient were male SD rats.The rats were divided into sham operation group (SHAM group),liver transplantation group,minocycline group (MIN group),atractyloside + minocycline group (ATR + MIN group),24 rats in each group.In the MIN group,10 mg/kg minocycline was injected through the dorsum vein of the penis after reperfusion.The ATR + MIN group was injected with 2 mg/kg atractyloside.The open status of mitochondrial permeability transition pore (mPTP) was detected at 2,6,and 24 h after operation.Western blotting and immunohistochemistry were used to detect the expression of caspase3 and cyt c.Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were determined.Liver tissues were stained with hematoxylin-eosin (HE) and pathological changes were evaluated by Suzuki's standard.The survival of each group was calculated.Results As compared with liver transplantation group and ATR+ MIN group,the mPTP opening of MIN group decreased (P＜0.05),the expression of caspase3 and cyt c and the serum ALT and AST levels decreased significantly (P＜0.05),liver tissues injury was alleviated (P＜0.05),and the survival rate increased significantly after 30 days (P ＜0.05).There was no significant difference between liver transplantation group and ATR + MIN group (P ＞ 0.05).Conclusion Minocycline reduces ischemia-reperfusion injury in DCD liver transplantation in rats probably by inhibiting the mPTP opening,and preventing cyt c release and caspase3 activation to reduce hepatocyte apoptosis.This effect can be blocked by mPTP opener.
