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.

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.

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 To study the mental hea lth of drug addicts and its correlation with addictive behavior. Method s 143 drug addicts in treatment were investigated and analyzed with The Symptom Checklist 90 and Addictive Behavior Questionnaire. Results The mental health of drug addicts was worse than that of normal peo ple, and somatization, depression, anxiety and psychopathy in the factor of SCL -90 had high proportion in high score field. Sex, having occupation or not, and living alone had no significant differences in SCL-90 score. The results of co rrelation analysis of mental health and addictive behavior were that the quantit y and frequency of drug use had positive correlation with mental health. The con trol power of drug use desire had negative correlation with mental health. Conclusion The mental health of drug addicts is worse, and addi ctive behavior is correlated with mental health.

Objective To evaluate the efficiency of ten years of iodized salt supply in prevention and control of iodine deficiency disease (IDD) in Tianjin. Methods 1 200 pupils aged 8-10 years with 1:1 of sex ratio were chosen in the regions where iodized salt supply had been conducted for 10 years (1995-2005), the prevalence rate of goiter, the level of urine iodine and the iodized salt consumption were investigated. Results The prevalence rate of goiter of children aged 8-10 years in Tianjin decreased from 32.6% to 1.8% after 10 years of iodized salt supply, the median of urinary iodine increased from 96 ?g/L to 228 ?g/L. In the high water iodine regions, the prevalence rate of goiter was 8.1%, the median of urinary iodine was 576 ?g/L. Conclusion 10 years of iodized salt supply can significantly prevent and control IDD in the regions where there is iodine deficiency in drinking water, but the problem should not be neglected that iodine excess in the regions where the concentration of iodine in drinking water is higher. Reasonable iodine supplement is the key to prevent and control IDD as a whole.

Objective To evaluate the relationship between fragile histidine triad(FHIT) transcription abnormalities and HPV16 infection and human cervical tumorigenesis.Methods Total RNA from 5 cervical carcinoma cell lines(SiHa,HeLa,RJC-1,CS1213 and C4-1),58 primary cervical cancer specimens and 18 normal cervical epithelial tissues were extracted and FHIT transcripts were characterized by a two-step(nested) reverse transcription(RT)-PCR.The seven of the PCR products with different size were purified and sequenced.HPV16 infection was assessed by PCR.Results ① There were altered FHIT transcripts in SiHa,HeLa and C4-1 cells.Aberrant FHIT transcripts were detected in 39 out of the 58 cervical cancer samples(67.2%),but none out of 18 in the normal cervix tissue specimens(0%);HPV16 infections were identified in 37 of the 58 cervical cancer tissues(63.8%),but 1 in the 18 normal cervical epithelial tissues(5%),which showed a significant difference between these two groups(P0.05).③ The exon 5 and exon 6 were mainly deleted in the altered FHIT transcripts and no insertion and point mutation were found by DNA sequencing.Conclusion Aberrant FHIT expression was significantly common in cervical cancers and was correlated with HPV16 infection.These findings suggest that the tumor suppressor gene FHIT and high risk HPV16 may play a very important role in human cervical carcinogenesis.

Objective To investigate the role of oestrogen receptors and enteric mast cells in the pathogenesis of irritable bowel syndrome (IBS) . Methods Biopsies from 59 patients with IBS and 24 control subjects were analyzed blindly for the number of mast cell ( MC ) , estrogen receptors and progestogen receptors in terminal ileum , caecum and descending colon (DC). Immunohistochemical methods were used to detect the estrogen receptors (ER) , progestogen receptors (PR) and MC. And double Immunohistochemical staining was used to manifest the expression of oestrogen receptors in intestinal MC. Results The cells positive for ER were morphologically similar to the MC (R = 0. 884, P

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.
