People′s misunderstandings about the radiological check in health examination: Equalize the price of the medical check equipment with the accuracy of the check .The health examinees′misunderstanding about the harm which X-Ray can cause , thinking that low dose chest CT only can do very little harm to human body .The health examination unit makes the rate of finding out early lung tumor a main basis of assessing a medical personnel ′s achievement , which caused medical staff go against epidemiological laws when diagnosing tiny nodules .Misun-derstandings about some biological features such as the scale or the growing speed of the nidus , and laying exces-sive importance on the check accuracy , which caused some examinees received excessive X -Ray, overdiagnosis and overtreatment .So, people must treat radiological check in health examination rationally and dialectically , in order to further realize the legitimation and rationalization of radiological check .

As a part of the central nervous system,retina shares many characters of the brain,including many of the functions and dysfunctions of microglia.Microglia plays important roles in multiple inflammatory procedures and degenerative diseases of the central nervous system and retina.Retinal microglia is involved in ocular inflammatory,age-related macular degeneration and diabetic retinopathy.These cells have also been identified in brain tumor and retinoblastoma.They can secrete various cytokines and growth factors that may contribute to the successful immune evasion and therefore promote the growth and invasion of tumor.To better understand the function of microglia is essential for us to develop the immune-based treatment strategies against central nervous system tumor and retinoblastoma.

ObjectiveTo evaluate the effect of health education combined with psychological counseling on mental state of patients with coronary heart disease complicated with anxiety and depression. Methods70 cases of patients with coronary heart disease with anxiety and depression were divided into the observation group and the control group with 35 cases in each group.The control group received regular professional care,while the observation group was given health education combined with psychological counseling on the basis of regular professional care.The SAS and SDS score was compared between the two groups. ResultsAfter treatment,SAS and SDS score of two groups apparently improved.After treatment,SAS and SDS score of the observation group was less than the control group. ConclusionsHealth education combined with psychological counseling for patients with coronary heart disease complicated with anxiety and depression can effectively alleviate the anxiety and depression emotion of patients and increase life quality of them.

Objective To explore and establish the possible method of low-intensity pulsed ultrasound(LIPUS) irradiation directly combined with SonoVue microbubbles could enhance 5-azacytine (Aza) induced cardiomyogenic differentiation of human bone marrow mesenchymal stem cellin(MSCs)vitro,initially explore the appropriate irradiation condition,and to provide experimental basic data for ultrasound-mediated microbubble destruction application in MSCs transplantation for acute myocardial infarction.Methods (1) In order to screen out the appropriate ultrasound irradiation intensity and time without conspicuous harm to MSCs,stem cells were exposed to different ultrasound intensity irradiation (0.11,0.33,0.55,0.77,0.99 W/cm2) and time (0,30,60,90 s) and then cell proliferation determined by methyl thiazolyl tetrazolium(MTT).In order to screen out the appropriate microbubble-to-cell ratio without conspicuous harm to MSCs,stem cells of different microbubble-to-cell ratios (0,10,50,100,150) were exposed above the screened ultrasound irradiation intensity and time and then cell proliferation determined by MTT.(2) MSCs were divided into four groups and induced cardiomyogenic differentiation by different inducing systems in vitro as follows:no-treatment group,5-Aza inducing group(10 μmol/L),microbubble and ultrasound group,5-Aza inducing (10 μmol/L) with microbubble and ultrasound group,followed by four weeks of further culture.The morphological changes were studied daily under phase-contrast microscope,then the expression of cardiac troponin-T (cTnT) was detected by immunocytochemistry method to analyze and compare differentiation rate of cardiomyocyte-like cells in each group.Results (1)The direct ultrasound irradiation condition of no conspicuous harm to MSCs,but with destruction was intensity of 0.55 W/cm2,exposure time of 30 s and microbubble-to-cell ratio of 50.(2) This study confirmed the feasibility of direct ultrasound exposure of LIPUS on MSCs in vitro.(3) At 28 days after induction,the stem cells of 5-Aza inducing group and 5-Aza inducing with microbubble and ultrasound group expressed cTnT and the positive rate of the latter was higher than the former by immunocytochemistry (13.69％ vs 34.13％,P ＜0.05).Conclusions The appropriate ultrasound direct irradiation condition was intensity of 0.55 W/cm2,exposure time of 30 s and microbubble-to-cell ratio of 50.Appropriate conditions of LIPUS could enhance 5-Aza induced cardiomyogenic differentiation of MSCs in vitro.

Objective Understand the hospital surgical treatment of female infertility patients after discharge health needs,to provide evidence for continuity of the corresponding nursing measures.Methods After surgical treatment of hospital preparation of hospital,100 cases of infertility patients designed questionnaire,to understand the patient's health requirements.Results About 94％ of patients had continuity care needs,The need for continuity care content in the top three:observation,the knowledge of the disease,mental health counseling.Continuity of care means demand is in the top three:We Chat public information push,add patients group of exchange of experience and telephone follow-up on a regular basis.Conclusion the hospitalized patients with infertility of the continuity of care after discharge and demand is high,enhancing health education for patients after discharge,the continuity of the individualized modern nursing measures,improve the patients discharged from hospital after conception rate and quality of life.

Objective To discuss the clinical observation of Montmorillonite combined with Compound Eosinophil-Lactobacillus Tablet in the treatment of pneumonia infants of antibiotic associated diarrhea (AAD).Methods Eighty pneumonia infants with antibiotic associated diarrhea were selected,they were divided into two groups according to the random number table method.The observation group (41 cases) was given Montmorillonite.The control group (39 cases) was given Montmorillonite and Compound Eosinophil-Lactobacillus.The efficacy of Montmorillonite combined with compound Eosinophil-Lactobacillus Tablet in the treatment of pneumonia infants of antibiotic associated diarrhea was evaluated by efficacy,clinical symptom,immune function changes and adverse reactions during the treatment period.Results After treatment,the effective rate of observation group was higher than that of the control group (P ＜ 0.05).After treatment,the fever time,correcting dehydration time,and antidiarrheal time of observation group was shorter than that of the control group (P ＜ 0.05).After treatment,the serum IgG,IgA,and T lymphocyte subsets of CD3+,CD4+ levels were significantly increased in the observation group (P ＜ 0.05).There was no statistical significance on CD8+ before and after treatment.In contrast,there were no statistical significance on the serum immunoglobulin and T lymphocyte subsets before and after treatment in the control group.During the treatment period,no adverse reaction occurred in two groups.Conclusion In summary,Montmorillonite combined with Compound Eosinophil-Lactobacillus Tablet had a good effect on AAD.They could quickly improve the symptoms of diarrhea and immunoglobulin levels in children.It was worthy of clinical use.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disorder of hematopoietic stem cells due to acquisition of somatic mutations.Somatic mutations in phosphatidylinositol glycan class A (PIGA) account for intravascular hemolysis and other PNH manifestations,but the pathophysiology of clonal expansion of PNH cells cannot be elucidated clearly.PNH is closely related to aplastic anemia and myelodysplastic syndromes.Today,the gold standard for PNH is flow cytometry to detect the absence or severe deficiency of glycosylphosphatidylinositol (GPI)-anchored proteins on white and red blood cells.However,PNH diagnosed by phenotype is a group of heterogeneous disease in pathogenesis.Eculizumab,a first-in-class monoclonal antibody that inhibits terminal complement,is highly effective in stopping intravascular hemolysis and improving quality of life.Further research on the pathogenesis of PNH would be helpful to understand the underlying reasons for PNH phenotype cells in different patients,improve differential diagnosis and more targeted and specific therapy.Research progress in recent years will be reviewed in this article.
