Brain cell microenvironment,also known as cerebral tissue channel,consists of the brain extracellular space and its contents.For a long time,because of the limit of technology,the research about brain extracellular space hasn't been given enough attention in the field of cognitive sciences and neuroscience.With the development of medical imaging technology,the research about brain extracellular space will open up a new space for brain and cognitive sciences,and provide a new approach for diagnosis and treatment of encephalopathy.Based on the method of medical informatics,this article reveals hot topics on brain science,presents the history of the research about brain cell microenvironment,and analyzes the construction of neurology literature so as to provide reference for the future researchers.

The Roles of the clinicians in different medical models are quite different,which not only led to the change of the relationship between the clinicians and the patients, but also had a significant clinical effect. The authors compared the clinicians'role in different medical models and showed the humanism underlying this change.

Objective To discuss whether potassium sensitivity test(PST) is correlated with PUF in Interstitial Cystitis (IC). Methods The data of 14 IC patients (female 13, male 1) were an-alyzed. The mean age was 48 years (range 35-67 years). The clinical symptoms included urinary fre-quency, urgency, pelvic and peritoneal region pain after bladder filling. All the patients met the diag-nostic criteria of NIDDK for IC. Dilatations by hyponome were performed, medicine including heparin-sodium, lidocaine, NaHCO3 were used by intravesical instillation. PST and the pelvic pain and urgen-cy/frequency patient symptom (PUF) were used for evaluation. The relationship of the PST and PUF was assessed by statistics. Results PST median decreased from 4.0 to 1.0 (P<0.01). PUF medi-an decreased from 27.5 to 13.5(P<0.01). PST was directly correlated with PUF (rs=0. 868, t= 4.418, P= 0.001 before treatment, rs = 0.779, t=4.300, P = 0.001 after treatment). Conclusions PST and PUF are correlated. Both can be used as index in diagnosis, differential diagno-sis, symptom severity and treatment effectiveness evaluation of IC.

Objective This investigation was to define the occupational security-related factors in community nurses and effective strategies to improve their service awareness and occupational protection ability.Methods A questionnaire was used for 1702 community nurses in Guangzhou to learn occupational security-related factors and occupational protection skills.Results Self-report results found that 21.3% (362/1702) nurses fully understood the occupational security-related factors,12.0% (204/1702) nurses knew the requirement for occupational security,and 12.3% (209/1702) nurse could provide occupational protection.Conclusions These results suggested that most community nurses showed poorer occupational protection awareness and ability.Thus,occupation safety management regulations,standardized performance procedure and emergency response plan should be put forward,and further community nurse training programme need to be initiated.

Chemokine CXCL9/Mig (monokine induced by IFN-?) belongs to the subfamily of chemotactic cytokines known as CXC-chemokines. In vivo CXCL9 is mainly induced by IFN-? in macrophages and primary glial cells. In vitro, CXCL9 can be secreted by cells such as macrophages, microvascular endothelial cells and neutrophils, in response to the synergy of IFN-? and TLR(toll-like receptor) ligands. CXCL9 is a chemoattractant for activated T lymphocytes, tumor-infiltrating T-lymphocytes, but not for neutrophils or monocytes. The receptor specific for CXCL9 is CXCR3, a G protein-coupled protein which has seven transmembrane domain. The structure and the chemical characterization of CXCL9, as well as its effects on autoimmune deseases, allograft rejection, cancer therapy were reviewed.

Objective To screen for clopidogrel metabolism related gene CYP2C19 in patients with coronary artery disease in Wuhan.Methods 316 patients,from Jan to Dec 2014,after cardiology percutaneous coronary interventional therapy (PCI) for the treatment of coronary artery disease were selected as research object.Clopidogrel metabolism related CYP2C19 geno-types (* 1,* 2,* 3)were detected by the gene chip,and for different types of metabolism of patients according to CYP2C19 gene type:strong metabolize type (*1/*1),intermediate metabolizer types (*1/*2,*1/*3),poor metaboli-zer types (*2/*2,*3/*3,*2/*3).Results According to the CYP2C19 gene polymorphism of metabolic function type, strong metabolic type carrying CYP2C19*1 (*1/*1)accounted was 43.4%,intermediate metabolizers carrying CYP2C19*2 or *3 (* 1/* 2 and * 1/* 3)and poor metabolizers (* 2/* 2,* 2/* 3 and * 3/* 3)accounted was 42.4% and 14.2%,respectively.Different gender had no statistical significance in CYP2C19 genotype differences.Conclusion Clopi-dogrel metabolism functional of CYP2C19 gene in patients with interventional coronary heart disease in Wuhan area had more deletion gene.

BACKGROUND:A large number of literatures have shown that surgeons expose to a higher radiation dose during puncture and bone cement injection in percutaneous vertebral augmentation. OBJECTIVE:To review the research progress in radiation doses and safeguard procedures in percutaneous vertebral augmentation. METHODS: By using percutaneous vertebral augmentation, radiation doses, radiation protective as key words, we retrieved articles related to radiological protection during percutaneous vertebral augmentation published from January 1995 to December 2014 in Wangfang database and PubMed database. RESULTS AND CONCLUSION:One basic principle of radiation protection is that the radiation dose decreases rapidly with distance from the radioactive sources. Surgeons should maximize the distance from the radioactive sources as far as possible in case there is no effect on the operation. To optimize the setting and position of C-arm machine, wear protective devices and put lead shields as wel as computer navigation and radiation training in surgeons al can help to reduce the radiation doses during percutaneous vertebral augmentation. Remote bone cement injection device is easy to control but not increases the radiation doses. In addition, the influence of surgery bed on radiation dose remains to be further studied. We believe that with the in-depth research on radiological protection, vertebral augmentation technique wil be safer in clinical application.

Background Phacoemulsification for hard nuclear cataract is easy to cause corneal edema and posterior capsular rupture.Researches determined that soft-shell technique phacoemulsification can effectively reduce corneal edema,but the risk of posterior capsular rupture during the surgery is still existed.Whether intra-capsular bag soft-shell technique can protect the posterior capsular of lens from rupture is still unclear.Objective This study was to observe the effect of intra-capsular bag soft-shell technique phacoemulsification on hard nuclear cataract.Methods A prospective cohort study was designed.One hundred and sixty-eight eyes of 160 patients with age-related cataract and Ⅳ-Ⅴ grade of nucleus were enrolled in Affiliated Second Hospital of Zhengzhou University from November 2013 to May 2015 under the approval of Ethic Commission and informed consent of the patients.The eyes were randomized into the intra-capsular soft-shell technique group and conventional soft-shell technique group with the matched age,gender and nuclear hardness in a manner of randomized block design.A 3.0 mm incision of cataract phacoemulsification with soft-shell technique in capsular bag was performed on 80 eyes of 78 patients in the intracapsular soft-shell technique group,and conventional soft-shell technique phacoemulsification was performed on 88 eyes of 82 patients in the conventional soft-shell technique group.Intraoperative records including the cumulative dissipated energy,effective phacoemulsification time and posterior capsular changes were recorded during the surgery.Postoperative follow-up indexes included corneal edema,endothelial cell density,BCVA and intraocular pressure changes.Results The mean cumulative dissipated energy and operation duration were (20.13 ± 8.34) ％ and (14.28-±2.17) minutes in the intra-capsular soft-shell technique group,and those in the conventional soft-shell technique group were (19.67±5.24)％ and (15.36±3.49) minutes,showing significant differences between them (t =0.216,P =0.376;t =0.403,P-=0.518).Posterior capsular rupture occurred in 1 eye in the intra-capsular softshell technique group and 7 eyes in the conventional soft-shell technique group.The percentages of eyes with BCVA ≥ 0.5 were 78％,83％ and 92％ in postoperative 1 day,1 week and 1 month in the intra-capsular soft-shell technique group,and those in the conventional soft-shell technique group were 56％,71％ and 89％,with a significant increase in postoperative 1 day,1 week in the intra-capsular soft-shell technique group (x2 =5.130,P =0.027;x2 =4.361,P =0.032).The corneal endothelial cell loss rates were 6.97％ and 7.19％ in the intra-capsular soft-shell technique group and conventional soft-shell technique group respectively in postoperative 3 months,with no significant difference between them (P＞0.05).The intraocular pressure was (20.16±4.23) mmHg (1 mmHg =0.133 kPa) in postoperative 1 day in the intra-capsular soft-shell technique group,which was significantly higher than (17.38± 5.21) mmHg in the conventional soft-shell technique group (t =1.241,P =0.037).Conclusions Intra-capsular bag soft-shell technique phacoemulsification for hard nuclear cataract can decrease the intraoperative and postoperative complications and quicken the visual recovery after surgery.

This review focuses on the fetal origins of adult disease hypothesis put forward by David Barker and his colleagues,recent advances in epidemiological studies and experimental research in this field.Barker Hypothesis states that environmental factors,particularly intrauterine nutrition,as indicated by birth weight,operate in early life to program the risks for adverse health outcomes in adult life.A large growing body of reports described the association between the early development and adult diseases,such as diabetes,hypertension,coronary heart disease,abnormal lipids metabolism,obesity and cancer,etc.Experimental studies show that the changes of some key genes' expression,caused by epigenetic modifications,lead to a permanent alteration of cellular proliferation and differentiation and finally the genesis in key tissues and organs.These results bring about the impairment in structures and functions and the increased susceptibility to chronic diseases in adult life.The hypothesis provides a new perspective for the prevention and therapy of chronic diseases.
