Protocarcinogenic gene Her-2/neu was closely related to the development of gastric cancer. Herceptin is an antibody according to Her-2/neu and is used for treating breast cancer. Topo Ⅱ α is the important Nuclear enzymes needed by DNA duplicate, and is closely related to the proliferation of malignant tumors, so it is the important target enzymes of cancer chemotherapy. Her-2/neu and Topo Ⅱ α are located in the same chromosomes, there are correlation between the two genes' proliferation or loss. We reviewed the expression of Her-2/neu and Topo Ⅱ α in the stomach and the new progress of the correlation between the two genes home and abroad in this paper, which provides new methods for the prevention and treatment of gastric cancer.

Evidence has indicated that low doses of anti-tumor regimens can induce cell apoptosis in vitro, although different regimens induce apoptosis by different mechanism and pathway. In recent years, new tumor treatment strategy has been mainly focused on inducing tumor cell apoptosis. The present review discusses the advantages and disadvantages of inducing tumor cell apoptosis. The benefit of inducing apoptosis is not to cause inflammatory reaction, but as its disadvantage, it inhibits immune responses, and the phagocytosis of apopotic bodies may result in horizontal transfer of genes (including oncogenes and other oncogenic materials), which can be one of the causes of tumor relapse. This paper proposes that the tumor treatment strategy should be turn into promoting tumor cell necrosis and inducing anti-tumor immune responses.

Objective:To study the biological characteristics of condylar chondrocytes isolated from mechanical stress stimulated TMJ condylar cartilage of rats.Methods:The rat models of mechanical stress stimulated condylar cartilage were made by class III orthope-dic force for 14 days.The cartilage from control and experimental rats were observed in gross view.The cell harvest rate and viability were examined,proteomic analysis was performed.Results:After stress stimulation the thickness,the elasticity of condylar cartilage and number of chondrocytes were significantly reduced.The weight of mandibular cartilage was decreased(P<0.01).The harvest rate and the viability rate of the cells were decreased(P<0.01).The chondrocytes in the experimental group appeared to be elongated. Proteomic analysis showed that stress-related proteins,signal transduction proteins were up-regulated;cytoskeleton proteins,cell prolif-erative proteins were down-regulated.Conclusion:Mechanical stress stimulation of condylar cartilage may result in biological activity and protein changes of the condylar cartilage chondrocytes.

Objective To investigate the predictive value of plasma lipoprotein associated phospholipase A 2 (Lp-PLA2 ) in cere-bral infarction(CI) after transient cerebral ischemia attack (TIA).Methods Plasma Lp-PLA2 level was detected in 112 TIA pa-tients ,and the incidence rate of CI was observed on 7 ,30 ,90 d after TIA.Then the grouping was performed according to the Lp-PLA2 level ,and the predictive value of Lp-PLA2 in the risk of CI occurrence after TIA was evaluated.Results Among 112 patients with TIA ,27 cases (24.1% ) developed CI within 90 d;there were 17 cases(63.0% ) of CI after TIA in the Lp-PLA2 >207 μg/L group ,which were significantly higher than that in the 175-207 μg/L group and <175 μg/L group (P<0.05);moreover the CI occurrence in TIA patients was mainly concentrated within 7 d after onset ;the patients of Lp-PLA2 ≥175μg/L were mainly distrib-uted in the moderate and high risk groups of ABCD2 score system ;in ROC curve of Lp-PLA2 for predicting CI after TIA ,with Lp-PLA2 ≥194 μg/L as the diagnostic critical point ,the sensitivity was 0.730 and specificity was 0.680.Conclusion Lp-PLA2 may be an effective risk predictive indicator of CI occurrence after TIA ,and can improve the adverse outcome of TIA patients.

Objective To investigate the associated risk factors of postoperative complications after rad?ical resecting of colorectal cancer. Methods The clinical data of 237 patients with colorectal cancer performed radical resection in the Second Affiliated Hospital of Kunming Medical University from January 2011 to Decem?ber 2014 were analyzed retrospectively. The incidence of postoperative complications was analyzed,and the relat?ed factors were analyzed by single factor and multi factor correlation analysis. Results The postoperative com?plications occurred in 114 cases of 237 patients( 48. 1%) . Univariate analysis showed that the age more than 70 years old,preoperative comorbidity,intraoperative blood loss,surgeon’ s experience,combined evisceration or en?larged evisceration were related to postoperative complications ( P = 0. 033, 0. 014, 0. 045, 0. 028, 0. 040 ) . Compared with the patients without complications,the postoperative anal exhaust time,length of stay was longer of the patients with complications((3. 7±1. 6) d vs. (3. 2±1. 4) d,P=0. 035;(21. 3±6. 5) d vs. (12. 1 ±2. 4) d,P=0. 001). Logistic regression analysis showed that depth of tumor invasion(P=0. 001),preoperative comorbidity including NRS>3 points (χ2 =8. 903, P=0. 003 ) , anemia and hypoproteinemia (χ2 =3. 494, P=0. 048) ,hypertension complicated with type 2 diabetes mellitus(χ2=5. 418,P=0. 026) ,not complete intesti?nal obstruction(χ2=8. 376,P=0. 003),mild and severe ventilation dysfunction(χ2=6. 331,P=0. 011) and WBC<3. 9×109(χ2=4. 256,P=0. 041) were closely related to the occurrence of complications. The rate of post?operative complication of laparoscopic group and open group had no significant difference( 44. 4%( 64/144) vs. 47. 3%(44/93),P>0. 05) . Conclusion Age>70 years old,preoperative comorbidity,intraoperative blood loss,surgeon`s experience,combined evisceration or enlarged evisceration are main risk factors for patients per?formed colorectal cancer radical resection,but laparoscopy?assisted radical resection is not the risk factor.

Up to date, eight types of human herpes viruses have been identified, all of which are ubiquitous, and usually establish latent infection in the host after primary infection. Since most of the herpes viruses are maintained in an asymptomatic form, they are often neglected. However, under some circumstances, these herpes viruses can cause fatal or severe diseases. Furthermore, the association of herpes viruses with hematopoietic malignancies is attracting researchers' attention. With the extensive development of hematopoietic stem cell and organ transplantation, reports regarding transplantation failure and complication caused by infection of human herpes virus has been increasing. Cytokine storm was firstly suggested as the mechanism of graft-versus-host diseases. In recent years, which has also been applied in the pathogenesis research of inflammation, and is supposed to play an important role in severe virus infection. In this paper, through discussing the possible role of latent infection of human herpes virus in the failure or complication of bone marrow or hematopoietic stem cell transplantation, and in refractory leukemia, the function and significance of latent infection of human herpes virus and the cytokine storm it caused were investigated.

Objective To observe the protection of human lens epithelial cells(HLEC) by different polar alkaloids extracted from Herba Dendrobii(HD).Methods We extacted the Herba Dendrobii powder with ethanol,and then treated the extract with falling-film concentration,acidification,salting out,chloroform extraction,and washing with water.Different polar alkaloids were extracted from HD after the above treatment.The protective effect of HD alkaloids was observed on HLEC,which were cultured with DMEM medium containing 10% fetal calf serum.Ten groups were set up for the experiment: normal control group,model group,high-and low-dose water-soluble alkaloids groups,high-and low-dose fat-soluble alkaloids groups,high-and low-dose low-polar alkaloids group,and high-and low-dose weak-polar alkaloids groups.The high-dose dosage of the alkaloids was 25.0 ?g/L and low-dose dosage was 12.5 ?g/L.Methyl thiazolyl tetrazolium(MTT) assay was used to evaluate the proliferation of HLEC under the different conditions of interventions.Results The single-factor experiments showed that the highest extracting rate of HD alkaloids was obtained under the conditions of extracting the powder with 80% ethanol for 3 times and for 3 hours.The results of protective experiment showed that the proliferation of HLEC in the model group was inhibited by hydrogen peroxide(H2O2),and the inhibitive rate was lower in low-dose fat-soluble alkaloids group than that in the model group(P
