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.

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.

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.

Cancer/testis(CT) antigens,of which more than 40 kinds have now been identified,are encoded by genes that are expressed normally in the human germ line,and are also expressed in various tumor types,including melanoma,and carcinomas of the bladder,lung and liver.These immunogenic proteins are being vigorously pursued as targets for therapeutic cancer vaccines.In this paper,the classification,expression and function of CT antigens are reviewed.
