Objective To study the efficacy of simple Chinese medicine steam spray and comprehensive rehabilitation nursing after facial burn deep Ⅱ degree.Methods 80 patients were randomized into the treatment group (40 cases) and the control group (40 cases).The treatment group was given the treatment of Chinese medicine steam spray.The control group was given the treatment of Chinese medicine steam spray,pressure therapy,physical therapy,rehabilitation training and psychotherapy.The clinical efficacy of two groups was evaluated respectively after 3 months.Results After 3 months,the skins of most of patients in the treatment group were nearly normal with no pigmentation and scar hyperplasia.The cure rate was 72.5 ％,the obvious effective rate was 12.5 ％,and the effective rate was 7.5 ％.Some patients in the control group were lightly and inconspicuously pigmented,but the pigmentation area was reduced.The colour of their skins was not different from that of the normal skin.The cure rate was 42.5 ％,the obvious effective rate was 12.5 ％,and the effective rate was 25.0 ％.The effects of the two groups were significant differences (P＜0.05).Conclusions Comprehensive rehabilitation nursing after the facial burn can reduce the pigmentation and scar hyperplasia and improve the quality of life.

As a novel T cell population,Th17 cells are demonstrated to play an important role in autoimmune diseases,including Crohn' s disease.Several recent studies indicate the specific contributions of IL-23/Th17 axis and cytokines secreted by Th17 cells to the inflammatory bowel disease.This article is dedicated to describe the correlation between Th17 cells and Crohn' s disease.

Excitatory amino acid toxicity is one of the mechanisms of vascular dementia. Gluta-mate is the major excitatory neurotransmitter in brain. Memantine, a moderate affinity, uncom-petitive and voltage-dependent N-methyl-D-aspartate (NMDA) receptor blocker, can block NMDA receptor-induced intracellular calcium overload and prevent excitotoxicity. It can be used in the treatment of vascular dementia.

Objective To understand the operation room nurses' job stress and mental health status and discuss the countermeasures to ease pressure. Methods 82 patients were selected from five hospitals from April to August 2010. We used symptom checklist, self-rating anxiety scale, self-rating depression scale and nurse' job stress scale to carry out the questionnaire survey. Results The pressure of operation room nurses were related with their mental health status. Conclusions Some problems existed in mental health and work stress in operation room nurses, which should be highly valued by operation room nursing managers.

Transient ischemic attack (TIA) is the most important early warning signal of cerebral infarction, and it is also the critical period for the prevention of cerebral infarction. If we effectively control the risk factors of TIA, the onset and the progress of TIA can be prevented and controlled, This article reviews the correlation between the risk factors of TIA and prognosis.

Chinese herbal prescription (CHP) is the main method and mean of clinical medication in traditional Chinese medicine (TCM). The CHP efficacy is the summary of multi-herb function under the guidance of TCM theories. With the development of modern science and technology, the scientific and organic interpretation of scientific connotation of CHP efficacy is a difficult problem in TCM. In this paper, the modern research ideas and methods of CHP efficacy, which greatly enriched the modern research content of CHP efficacy as well as promoted its research and development, were discussed and summarized.

Objective To investigate the correlationbetween thecarcinoembryonic antigen ( CEA) level and hypoxic status of breast cancer, and itspotential of being a prognostic factor in breast cancer. Methods Breast cancer cell line MDA-MB-231 was cultured under hypoxic or normoxic condition to determine the protein level of CEA using Western blotting.30 breast cancer tissue sections were collected in Tianjin Medical University Cancer Institute and Hospital from April 2013 to June 2015.and were detected the expression of CEA, hypoxia-inducible factor-1α( HIF-1α) and carbonic anhydrase-9 ( CA-9 ) by immunohistochemistry.Serum CEA were detected by immunofluorescence assay of 166 breast cancer patients collected from April 2009 to June 2011.The correlation between the expression levels of CEA and breast cancer patients'clinical data was analyzed by Logistic univariate analysis.Kaplan-Meier method was employed to calculate the progression-free survival of patients with breast cancer. Log-rank test was conducted to compare the difference between groups.Results CEA levels were significantly higher in breast cancer cells under hypoxic condition in a time-dependent manner, compared to normoxiccontrol. Immunohistochemical staining indicated that CEA was coexpressed with HIF-1αand CA-9 in breast cancer and linear regression analysis revealed that CEA expression correlated with HIF-1α( P =0.0096 );Preoperative serum levels of CEA were closely related with tumor size ( P =0.015 ) andLymph node metastasis(P=0.032); CEA positive patients achieved a progression-free survival of 29.85months(versus 39.08 months in CEA negative patients, P=0.003).Conclusions Hypoxia upregulates CEA expression in breast cancer and the levels of preoperative serum CEA is a potential prognostic factor ofbreast cancer.

Thirty-six subclinical hypothyroidism patients with different pathogenic background were treated by levothyroxine. After treatment the levels of serum total cholesterol, low density lipoprotein and triglyceride were significantly lower than those before treatment (P

CyberKnife is a newly developed technology in the field of stereotactic radiosurgery/radiotherapy(SRS/SRT).Compared with conventional SRS/SRT,there are many advantages for CyberKnife in terms of being real-time image-guided,frameless,highly accurate,etc.Recently,it has been used to treat different types of malignant carcinoma including intracranial and extracranial tumors.This article summarized the contemporary progress of CyberKnife in the treatment of intracranial and extracranial tumors.

Objective:To observe apical sealing ability of two kinds of nanomaterial. Methods:40 straight human maxillary anterior teeth were randomly divided into four experimental groups of 8 samples each and two control groups of 4 samples each. The root canals were prepared using step-back technique and obturated with gutta-percha and one of the sealers by the lateral condensation technique. Group 1: Filled with zinc oxide-eugenol sealer and gutta-percha (ZOE); group 2: Filled with hydroxyapatite sealer and gutta-percha (HA); group 3: Filled with nano-zinc-oxide sealer and gutta-percha (NZO); group 4: Filled with nanohydroxyapatite sealer and gutta-percha (NHA). The teeth were placed into microleakage model. Glucose leakage from the coronal to apical was measured by the concentration of glucose in apical reservoir at 1, 2, 4, 7, 10, 15, 20, 25 and 30 days with GOD (glucose oxidase ) method. The apical sealing ability of the materials were assessed according to the concentration of glucose leakage. Results:The glucose leakage of four kinds of materials differed significantly (P
