The lung is one of the important target organs of chemical poisoning. Chemical toxins may be absorbed into body through blood circulation of the lungs,inducing systemic damage. Mean?while,they may also directly damage the lungs themselves. Lung injury is usually rapid and life-threatening. This review systematically introduced the toxicological mechanisms and poisoning management of lung injury agents.

Pharmacognosy (Chinese Medicine) discipline has a long history and International cooperation is more and more frequent, but the communication of the Chinese traditional medicine cul-ture is very difficult. In order to solve this problem, it is urgent to improve the professional English level of the students. Thus, combined with the education survey and interview results, as well as the reports in previous studies and our own experience, we think about how to set pharmaceutical profes-sional English course and put forward some suggestions such as the innovation of curriculum organiza-tion strategy, convergence of basic English course, teaching content and form being closely linked to academic activities, and paying attention to highlighting the subject characteristics of pharmacognosy (Pharmacy).

Allograft rejection after xero organ transplantation rejection, especially acute rejection is still the major reason of failure and death. Active T cell play key roles in allograft rejection. It has been showed that the expressions of costimulatory molecules are associated with xero organ transplantation rejection. The pathways of CD28/CTLA-4 and CD40/CD40L are important costimulatory pathways that cause T cell activation.The article emphasizes on the role of CD28/CTLA-4-B7 pathway in allograft rejection.

Objective To explore the relationship of the mean color vessels density (MCVD) and pathologic microvessel density(MVD) in rectal cancers and their relation with T stags and lymph node metastasis.Methods MCVD were caculated preoperationly with transrectal color power angiography(TRCPA).After operation MVD was assessed immunohistochemically using anti-CD105 monoclonal antibody.The relationships within MCVD, MVD and T stages and lymph node metastasis were analysed.Results There were positive correlation between MCVD and MVD (r=0.763, P＜0.01) in rectal cancer.There were significant difference of MCVD and MVD in both the depth of carcinoma invasion and metastasis of lymphatic nodes( P＜0.05).Conclusions MCVD can display features of the blood supply and distribution of pathologic microvessels and reflect the development of rectal cancers.MCVD is a credible index to choose available treatment and to evaluate prognosis before operation of rectal cancer.

Objective To discuss the diagnostic value of soluble scavenger receptor(sCD163)for the patients of malignant tumor associated with fever in early infection .Methods Collect 102 cases of patients confirmed with malignant tumor in this hospi-tal since January to December 2014 ,all the patients were examined with blood culture .102 patients were divided into two groups ac-cording to the results of blood culture :infection group (60 cases) and uninfected group (42 cases) .ELISA ,electrochemical lumines-cence and immune transmission turbidimetric methods were used to detect the levels of sCD163 ,PCT and CRP in serum ,to compare the differences in the above indicators between two groups .The receiver-operating characteristic curve (ROC curve) was applied to evaluate the application value of sCD163 in diagnosing of malignant tumor associated with fever in early infection .Results The lev-el of sCD163 ,PCT and CRP had statistically difference in two groups(P< 0 .05) ;the critical values of sCD163 、PCT and CRP were 110 .80 ng/mL ,0 .45 ng/mL ,15 .60 mg/L respectively which can suggest the patients with malignant tumor complicated with fever in early infection .The area under the curve were 0 .894 ,0 .835 ,0 .743 respectively ,among that sCD163 area was the largest ;The corresponding sensitivity were 88 .9% ,77 .9% and 88 .0% ;specificity were 77 .0% ,74 .0% and 50 .0% respectively .Conclusion Compared with PCT ,CRP ,sCD163 has more value for diagnosing the patients of malignant tumor associated with fever in early in-fection .

Objective A classification for hepatic venous outflow obstruction after piggyback liver transplantation (PBLT) and its clinical significance.Methods We conducted a retrospective study on 248 patients who underwent liver transplantation from May 2000 to August 2006.The aims were to elucidate the causes and treatment of postoperative venous outflow obstruction.Results Venous outflow obstruction occurred in 38 patients after transplantation.Among those,2 (5.26％) had superior hepatic inferior vena cava (IVC) stenosis,13 (34,21％) had the hepatic vein anastomosis twisted at an angle,7 (18.42％) had IVC stenosis at the posthepatic segment,and 16 (42.10％) had outflow obstruction at the hepatic veins.In these 38 patients,34 underwent PBLT,2 underwent APBLT,and 2 COLT.Most patients with hepatic venous outflow obstruction improved with surgical treatment and interventional therapy.Conclusions Hepatic vein outflow obstruction was associated with the technique of hepatic vein anastomosis,the type of cavocaval anastomosis and graft size mismatch between the donor and the recipient.Performing piggyback liver transplantation according to the classification of hepatic vein and appropriate treatments could improve the prognosis of venous outflow obstruction in clinical practice.
