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.

Adenovirus as gene transfer vector is characterized by high transfection efficiency,high titer,good stability in target cells and low pathogenicity,and has been widely used in gene therapy.Compared to first-and second-generation adenovirus vectors,the third-generation adenovirus vectors have unique advantages for gene therapy because of their low immunogenicity and high capacity.However,the clinical application of the third-generation adenovirus vectors is hampered by the existance of helper contamination and difficulties in their large-scale production.

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.

This paper analyzes the influence of modern enterprise system on managerial mechanism and industrial management of pharmaceutical enterprise, and the countermeasure that should be adopted by enterprise are discussed as well.

Using proliferating inhibition test, the effects of three cultivars of black mushroom on the growth of gastric carcinoma cell in vitro were observed. We have found that the extracts of all three cultivars of black mushroom had inhibiting effects on the growth of tumor cells in medium at some levels, especially Cr-02 was the most evident one.The results suggest that black mushroom has some anti-tumor effects, and it is worthwhile to study farther for verification.

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.

Objective To evaluate the efficacy of dexmedetomidine mixed with ropivacaine for transversus abdominis plane (TAP) block combined with general anesthesia in the patients undergoing gynecological laparoscopy.Methods Ninety American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients, aged 20-50 yr, with body mass index of 18-24 kg/m2, scheduled for elective gynecological laparoscopic ovarian cyst resection under general anesthesia, were randomly divided into 3 groups (n =30 each) using a random number table: general anesthesia group (group G) , general anesthesia + ropivacaine for TAP block group (group G+R), and general anesthesia + dexanedetomidine mixed with ropivacaine for TAP block group (group G+DR).After the end of anesthesia induction, ultrasound-guided left-sided unilateral TAP block was performed in G+R and G+DR groups.In G+R and G+DR groups, 20 ml of 0.375％ ropivacaine and 20 ml of 0.375％ ropivacaine mixed with 1 μg/kg dexmedetomidine were injected, respectively.After induction of general anesthesia, the laryngeal mask airway (LMA) was inserted, and the patients were mechanically ventilated in the 3 groups.Anesthesia was maintenaned with iv infusion of remifentanil 0.2 μg · kg-1 · min-1 and propofol 4-8 mg · kg-1 · h-1.Narcotrend index was maintained at 37-46.Only group G received postoperative intravenous analgesia.The occurrence of TAP block-related adverse events was recorded.The emergence time, time for recovery of spontaneous breathing, time for removal of LMA, and Steward score at 5 min after removal of LMA were recorded.The occurrence of postoperative nausea and vomiting, and respiratory depression was recorded.Results Compared with G and G+R groups,the emergence time, time for recovery of spontaneous breathing, and time for removal of LMA were significantly shortened (P＜0.05 or 0.01) , and no significant change was found in Steward score in group G+DR (P＞0.05).There was no significant difference in the above parameters between group G and group G+R (P＞0.05).Compared with group G, the incidence of postoperative nausea and vomiting was significantly decreased in G+R and G+DR groups (P＜0.05).VAS score was maintained ≤ 3 after operation in the 3 groups.No TAP block-related adverse events were found in G+R and G+DR groups.Conclusion Dexmedetomidine mixed with ropivacaine provides faster recovery from anesthesia, and avoids postoperative hyperalgesia when used for TAP block combined with general anesthesia in the patients undergoing gynecological laparoscopy.
