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.

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.

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.

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.

Objective To probe the neuroprotective effect of memantine in hippocampal CA1 region of rats with vascular dementia(VD). Methods 36 male Wistar rats were randomly divided into sham-operated group,VD group and memantine group,and each group have 12 rats. Rats of VD were treated with a permanent bilateral common carotid arteries occlusion(2-VO). Then memantine was given by intragastric administration.The behavioral abnormalities were investigated by Y-type maze test.The changes of cell morphology and the expressions of neuronal nitric oxide synthase(nNOS) and cysteine proteinase-3 (Caspase-3) of neuron in hippocampal CA1 region were detected by HE stain and immunohistochemistry respectively.The percentage of neuronal apoptosis by TUNEL. Results Compared with VD group and sham-operated group,the performance records of learning and memory(learning records:63.16±1.75,79.25±2.01,50.83±1.80,F =707.91,P <0.01;memory records:53.17±1.85,69.17±1.70,40.67±1.83,F =762.43,P <0.01),the expressions of nNOS (average gray scale:140.23±2.30,175.87±3.34,105.63±3.52,F =1539.67,P <0.01)and Caspase-3 (average gray scale:132.78±5.36,162.78±5.25,99.54±5.06,F =439.37,P <0.01)and the percentage of neuronal apoptosis (33.75±2.70,56.17±3.56,6.33±3.65,F =672.91,P <0.01)of memantine group were in the middle. Conclusion Memantine can improve spatial memory and attenuate neuronal apoptosis by down-regulation excessive expression of nNOS and Caspase-3 in rats with vascular dementia.

Hypocalcemia often exists in critical illness children. Most of the sick children do not have an underlying disease of calcium homeostasis, and the mechanism of the hypocalcemia is complicated. Abnormal values of blood calcium may be a sign of critical illness and normalize spontaneously with resolution of the primary disease process. Hypocalcemia may be a autoprotection , and it may be harmful if we try to correct it. This article focuses on the theory and clinical treatment of hypocalcemia in critical illness children.

It is still controversial whether or not the severe pneumonia is associated with heart failure in children.Currently,we pay more attention to the pathophysiological procedure of heart failure,such as pneumonia complicated with respiratory failure,shock and myocardial injury.Pay attention to the cardiopulmonary interaction mechanism and systemic inflammatory response.According to different pathophysiological mechanisms,guide the treatment by monitoring the hemodynamic status.

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.

This article explains four cases of professor REN Ji-xue,including anasarca,serious blepharoptosis,head cold,summer diarrhea,from which we can find the laws of syndrome differentiation by him. In which,the key point of the pathogenesis of anasarca is spleen-qi deficiency, so replenishing qi and invigorating the spleen, warming yang for diuresis are the treatment nethod for anasarca. Sinking of qi due to deficiency of spleen leads to serious blepharoptosis and Invigorating Spleen and Replenishing Qi Decoction is the main prescription. The key pathogenesis of head cold is disharmony of nutrient qi with defensive qi, so regulating ying and wei, dispersing lung qi for resuscitation are the treatment methods, and both inside and outside therapies are in use. Cold-damp invasion of spleen is the main cause of summer diarrhea, so activating qi flowing and warming spleen and stomach, dissipating dampness for stopping diarrhea are used. Professor REN Ji-xue is good at taking different method according to different key point of the pathogenesis, so the efficiency is good. This is one feature of Professor REN in treating miscellaneous diseases.

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
