Lung cancer is one of the most frequent malignant tumors. Target therapy is a milestone of non-small cell lung cancer (NSCLC) treatment in the 21st century. Biomarker detections have provided a solid foundation for individualized treatment. This review mainly focused on significance of EGFR mutation detection in EGFR tyrosine kinase inhibitors (EGFR-TKIs) as first line, second line and maintenance therapy in NSCLC. Simultaneously, this review introduced predicting significance of EGFR FISH test for the response of TKI treatment, and analyzed potential predictive biomarkers for antiangiogenic agents and status of antiEGFR monoclonal antibody in NSCLC individual therapy.

The standard operating procedures (SOP) of tumor tissue bank (TTB) involves the collection, processing, storage, quality control of biological samples. It is also the key to the normal operation of TTB and strengthen the cooperation between them. Many countries have recognized the need for the establishment of TTB, but the prevailing issue is that TTB is lack of access to a set of SOP for high-quality tissue samples. To further standardize the construction of TTB will also be involved in information management and common data elements (CDE) development of TTB.

MicroRNA(miRNA) is involved in virtually all biologic processes, including cellular proliferation, apoptosis, and differentiation. Thus, miRNA deregulation often results in impaired cellular function and disease development, so miRNAs have potential therapeutic relevance. The elucidation of these processes regulated by miRNAs and the identification of novel miRNA targets in the pathogenesis of hypertension is a highly valuable and exciting strategy that may eventually led to the development of novel treatment approaches for hypertension. Several mechanisms have been implicated in the pathogenesis of hypertension: overactivation of therenin-angiotensin-aldosterone system (RAAS), dysfunction of the vascular endothelium, damnification of vascular smooth muscle. To maintain and restore target organ expression of miRNA stable may be a new strategy for treatment of hypertension. The article reviews pathogenesis of miRNA and hypertension, researches of miRNAs as biomarker and therapeutic target, discusses advances in miRNA-based approaches that may be important in treating hypertension.

From June 1976 to December 1989, 76 patients with cancer of the rectum of Duke's stage C2 disease were cured treated by surgical resection . 54 patients received surgery only, 22 patients received surgery in combination with postoperative radiation therapy. Follow-up rate was 98%. Radiotherapy regimen in this study was 40～50 Gy in 4～5 weeks to the pelvic. The results showed that postoperative irradiation group had lower recurrence and distant metastasis rates(48.9%) than those of surgery alone one (96.1%). Survival in patients receiving postoperative radiation was substantially better(40.4%) than surgery only group(14.4%).

Objective:To investigate the effect of PBL+LBL double-track mode in Ophthalmology teaching.Methods:121 students were divided into two groups.Trial group practiced PBL+LBL double-track teaching,while control group practiced LBL teaching.Results:The results of exam showed that the students in trial group had a significant higher score in sum score and analysis subjects than those in control group(P

Objective To investigate the effects of ketamine on endotoxin-induced production of proinflammatory cytokines (IL-6, TNF-?) and activation of their modulating factor NF-?B in rat. Methods Thirty-six adult male Wistar rats weighing 250-300 g were randomly divided into 4 groups : (Ⅰ Ⅰ ) control group ( n = 6) ; (Ⅱ) endotoxin group received intravenous endotoxin ( Escherichia coli O111: B4)5mg?kg-1(n = 6); (Ⅲ) ketamine group received ketamine 50 mg?kg-1 ? h-1 i.v. (n = 6) and (Ⅳ) endotoxin + ketamine group received ketamine 0.5 or 5 or 50 mg?kg-1 ? h-1 after endotoxin ( n = 18 ) . The animals were anesthetized with urethane i. p. (1 g?kg-1) . Carotid artery was cannulated for BP and HR monitoring and jugular vein was cannulated for fluid or drug administration. Two hours after endotoxin administration the animals were sacrificed by exsanguination. Blood was collected and peripheral blood monocytes (PBMC) were isolated. NF-icB content in PBMC was measured by EMSA and plasma TNF-? and IL-6 concentrations were determined by ELISA. Results Progressive hypotension and tachycardia developed after endotoxin administration. Endotoxin also increased NF-icB content in PBMCs and plasma TNF-? and IL-6 concentrations. Ketamine 50 mg?kg-1 attenuated the endotoxin-induced hemodynamic response. Ketamine (0.5, 5, 50 mg?kg-1?h-1 ) suppressed NF-?B content in PBMC and inhibited plasma TNF-? level but plasma IL-6 level was not affected. Conclusion Ketamine can suppress endotoxin-induced NF-kappa B activation. Subanesthetic dose of ketamine has anti-inflammatory action.

Objective To investigate the effect of cluster nursing on quality of life and mental state of cervical cancer patients receiving chemotherapy. Methods 72 cervical cancer patients receiving chemotherapy were randomly divided into control group and observation group.The control group was given routine care and the observation group was given cluster nursing on the basis of routine care.The quality of life core questionnaire (EORTC QOL-C30) and Symptom Checklist SCL-90 score were tested at the end of treatment. Results Compared with the control group, after using cluster nursing, the EORTC QOL-C30 functional areas of physical function role function, cognitive function , social function, emotional function of patients in the observation group were significantly improved( <0.05), the main symptoms of nausea areas vomiting and pain were decreased significantly ( <0.05),and sleep,diet,diarrhea and constipation were improved significantly (<0.05) . SCL-90 scale showed that the somatization,obsessive-compulsive symptoms,depression and anxiety in observation group were decreased significantly compared with the control group ( <0.05),the somatization, obsessive-compulsive symptoms and anxiety were increased significantly in control group compared with China norm (<0.05) .Conclusion Cluster nursing on patients with cervical cancer receiving chemotherapy can effectively improve quality of life and reduce the incidence of negative emotions.

Human serum albumin (HSA) is a small molecule, non-glycosylated, negatively charged serum protein, and due to its flexible structure it possesses multiple functions, such as it acts as a carrier in the plasma by binding and transporting various substances, helps preserve the integrity of vascular endothelium, and it also possesses functions of anti-oxidation, anti-inflammation, protection of organ function, and maintenance of colloid osmotic pressure. HSA has been used as a therapeutic agent for critical ill patients for a long time. Comprehensive and meta analysis based on previous studies revealed that HSA has a certain effect in lowering incidence of complications in the treatment of critical disease. For some diseases, like sepsis, hepatocirrhosis complicated with spontaneous bacterial peritonitis, etc., the use of HSA can significantly improve the prognosis of the patient, however, its positive role in reducing overall mortality rate is still undetermined.

Objective To understand the status quo of pre-deployment training for PLA peacekeeping medical unit and to propose suggestion for improvement. Methods Questionnaire survey, spot investigation and seminars were used in this study. The participants included those who had attended the pre-deployment training for PLA peacekeeping medical unit from five military area commands, namely, Shenyang, Beijing, Lanzhou, Chengdu, and Jinan, and the international military medical students in Second Military Medical Universitiy. Microsoft Excel and SPSS 21.0 were used for data processing and analysis. Results PLA commands of different levels all attached great importance to peacekeeping health service, and the candidates for peacekeeping were of high quality, but their English communication ability needed improvement. Pre-deployment training was carried out by different units themselves, with poor training facilities, lack of experienced teachers, text books, and scientific test evaluation system. Conclusion More attention is needed on English communication training for PLA peacekeeping medical unit. A training base for PLA peacekeeping mission should be established, and the training should be carried out by a third party in a standard and intensive manner.
