Objective To compare the differences of safety and immunogenicity of DTaP-IPV-Hib-HepB hexavaccine,DTaPIPV-Hib pentavaccine plus HepB single vaccine or DTaP-IPV-HepB pentavaccine plus Hib single vaccine,so as to provide a reference for the marketing and use of hexavaccine in China.Methods Randomized controlled trials(RCTs)of DTaP-IPVHib-HepB hexavaccine,DTaP triple vaccine,Hib,IPV and HepB vaccines published at home and abroad were searched.The safety and immunogenicity of the hexavaccine were evaluated by Meta-analysis using Revman 5.4.1 software.Results A total of 7 articles,8 RCTs and 3 429 subjects were included. Meta-analysis of safety showed that there was no significant difference in the incidence of injection site and systemic adverse reactions after vaccination with hexavaccine and pentavaccine plus single vaccine(P > 0. 05)except for induration at the inoculation site and crying. Meta-analysis of immunogenicity showed no significant difference in antibody indexes after vaccination with hexavaccine and pentavaccine plus single vaccine(P > 0. 05).Conclusion The safety and immunogenicity of DTaP-IPV-Hib-HepB hexavaccine in basic immunity was comparable to that of the control vaccine,and might be applied to infants and young children to prevent related diseases. However,due to the limitations of the quantity and quality of included studies,the above conclusions still depend on the further development of larger sample,multicenter and high-quality

Tumor dormancy is a phase of occurrence and progress of cancer.In recent years,with the further study of circulating tumor cells,disseminated tumor cells and cancer stem cells,it is found that they are closely related to the tumor dormancy.Moreover,tumor microenvironment is another important factor in tumor dormancy.

Small fiber neuropathy is a peripheral neuropathy that selectively involves unmyelinated C-type fibers and (or) thin myelinated Aδ-type fibers. It is mainly manifested as abnormal pain and temperature perception and autonomic symptoms. Changes in certain inflammatory markers and antibodies related to autoimmune diseases can occur in patients with immune-related small fiber neuropathy. This article aims to explore the immunological progress in small fiber neuropathy.

Objective To establish a model of isoniazid induced necrosis and apoptosis in HepG2 cell and to observe the expressions of Fas/Fas ligand (FasL) in this model.Methods HepG2 cells were treated with different dosages of isoniazid (0,1,2,4,6 and 8 mg/mL) or blank control for 24 hours.Flow cytometer was used to observe the cellular morphology of the HepG2 cell.Annexin V/propidium iodide double staining and flow cytometry were employed to detect the necrosis and apoptosis of HepG2 cells.The expressions of Fas/FasL on the cells were also determined by flow cytometry.The data were analyzed by one-way ANOVA.The comparisons between the drug groups and the control group were performed by using Dunnett t test. Results The higher the dose of isoniazid (4,6,8 mg/mL) was,the more necrosis and apoptosis were observed.In the 4,6 and 8mg/mL isoniazid arms,the total mortality rates were all higher than the control group [(32.1 ±7.5)％,(34.9±8.1)％,(38.2±9.4)％ vs (7.2±1.5)％ respectively](t=4.62,5.14 and 5.75,respectively; all P＜0.01 ).The expression levels of Fas increased along with the dose of isoniazid increasing [(8.7±2.2)％,(11.5±2.8)％,(12.3±3.0)％ and (10.6±2.9)％ in isoniazid 2,4,6and 8 mg/mL arms,respectively],which were all higher than that in control arm [(3.1 ±0.8) ％](t=2.97,P＜0.05; t=4.46,P＜0.01; t=4.88,P＜0.01; t=3.98,P＜0.05).Furthermore,the expressions of FasL increased as well when the dose of isoniazid increased.The expression levels of FasL were (16.2±3.5)％,(21.7±4.8)％ and (18.7±4.9)％,respectively in isoniazid 4,6 and 8 mg/mL arms,which were all higher than that in the control group [(7.4±1.4)％](t=3.11,P＜0.01; t=5.06,P＜0.01; t=3.99,P＜0.05).HepG2 cell necrosis increased with isoniazid of 8 mg/mL.However,the increase of apoptosis was not observed.Conclusion Isoniazid can induce HepG2 cell necrosis and apoptosis,and the apoptosis may be related with the increased expressions of the Fas/FasL on the cells.

Objective To study previous cesarean section effects on re-eesarean section, and to seek better operation way of cesarean section. Methods The conditions of entrance into abdominal cavity and adhesion of 452 cases of abdominal cavity were retrospectively analyzed. The information about initial operation was investigated, dis-covering 104 cases underwent new type,and 348 cases underwent improved cesarean section. Results Time of en-trance into abdominal cavity once more by new type of cesarean section were (9.25±2.27) min and the incidence of adhesion in abdominal cavity was 18.27%,while time of entrance into abdominal cavity once more by improved cesarean section were (7.23±2.21) min and the incidence of adhesion indominal cavity was 9.87% (u=8.016, P<0.05; χ25.57,P<0.05). Conclusion New type of improved cesarean section has little effect on re-cesarean section, worthing more clinical practice.

Objective The aim of this study is to provide guidance on rehabilitation nursing via observing the effect of comprehensive relaxation training on perioperative psychological stress in patients with coronary intervention treatment. Methods In this study, eighty patients ready to receive coronary intervention were randomly divided into the experimental group and the control group (40 patients in each). The control group were treated with routine percutaneous coronary intervention care, and the experimental group received both comprehensive relaxation training and routine care. The anxiety state and subjective feelings on comprehensive relaxation training in both groups were dynamically investigated via State-Trait Anxiety Inventory questionnaire and subjective feeling questionnaire from pre-operation to 7 days after operation. Results Anxiety levels between two groups showed the similar trend, and there was statistically significance between two groupsin the state anxiety level. The subjective feeling in the experimental group improved. Conclusions The psychological stress in patients receiving coronary intervention surgery maintains at high level form pre-operation to 24h post operation, and comprehensive relaxation training can significantly reduce the level of state anxiety. These patients consider that this simple training shows obvious relaxing effect.

The expression of CD107a,NKG2D on the surface of natural killer (NK) cells and serum soluble major histocompatibility complex class Ⅰ chain-related A (sMICA) level in patients with extranodal NK/T cell lymphoma,nasal type (ENKL) were detected.We found that CD107a expression was reduced on the surface of NK cells,suggesting impaired NK cell activity in ENKL patients,which may result from decreased NKG2D expression.

Objective To preliminarily evaluate the diagnostic value of co registration and fusion of positron emission tomography and MR images in Alzheimer disease (AD). Methods Twelve patients with AD (53-83 years) and six normal volunteer (45-71 years) were scanned by positron emission tomography (PET) and MR imaging. The interval between two examination was 1-32 days (average:18 2?11 6 days). The disc and magnetic tape were used to transfer the imaging data to image work station (SGI O 2), then the special software for co registration and fusion: Statistical Parametric Map was used to do automatic co registration between PET and MR images of brain in 3D. Results The findings of PET was completely accorded with the changes of AD in 9 patients (9/12), and accorded with AD, but should be differentiate from other diseases in 3 cases (3/12). According to the measurement of special cerebral structures, MR images could make the diagnosis of AD in 11 patients (11/12), and had no abnormal finding in 1 case. The medial temporal atrophy could be seen on the MR images co registrated with PET in AD patients, on the other hand, PET demonstrated the pink color region of metabolic rate of glucose decreased in temporoparietal lobes of cerebral hemisphere. The similar findings depicted on fusion images as red color region of metabolic rate of glucose decreased in temporoparietal lobes. Conclusion The co registrated images can accurately observe the abnormal findings of PET and MR images, and fix the location of foci depicted by PET, in addition, fusion images increase the contrast of the foci. Analyzing the images of co registration and fusion of PET and MRI can lead to the diagnosis of AD in all the patients.
