S100B is a class of acid calcium-binding protein. It mainly exists in neuroglial cells in the central nervous system, and it is one of the signs of astrocyte activation. S100B may reflect the function of neuroglial cells and regulate the complex interactions between the neurons and neuroglial cells. Studies in recent years have demonstrated that S100B protein is involved in the pathological processes of acute ischemic brain injury. Serum S100B protein can be used as an important marker for identifying the severity of cerebral infarction, progress and outcome.

OBJECTIVE: How to promote the generation of neural stem cells (NSCs) and induce them differentiate into the goal cell type has been the focus of neuroscience. In this article, we review the adjustment of basic fibroblast growth factor (bFGF) and epidermal growth factor (EGF) to the proliferation and differentiation of NSCs. DATA SOURCES: A computer-based online search of Medline database was undertaken to identify the related articles published in English from January 1998 to March 2006 by using the keywords of "bFGF, EGF, nerve stem cells". At the same time, Chinese relevant articles were searched in China National Knowledge Infrastruction published between January 2000 and March 2006 with the same keywords in Chinese. STUDY SELECTION: The data were selected firstly to look over the citations of every literature. Inclusive criteria: Articles related to the effect of bFGF and EGF on the proliferation and differentiation of NSCs. Exclusive criteria: Duplicate research or Meta analysis. DATA EXTRACTION: A total of 78 related articles were collected, of which 32 accorded with the inclusive criteria and 46 with duplicate or old contents literatures were eliminated. Among the 32 literatures, 8 involved in the research status of NSCs, 10 about the effect of bFGF on the proliferation and differentiation of NSCs and the mechanism, 4 involved in the effect of EGF on the proliferation and differentiation of NSCs and the mechanism, respectively, 8 related to the effect of bFGF and EGF together, and 5 related to the comparison of the effect of bFGF and EGF. DATA SYNTHESIS: ①NSCs are self-renewed, and can differentiate into different stem cells and mature tissue cells in different microenvironment. Many cytokines in the microenvironment play essential roles in the differentiation direction of NSCs. ②bFGF has strong improvement effect on the proliferation of NSCs and can activate the potential regeneration capacity of neuronal precursor cell in distinct areas of central nervous system, proliferation and differentiation of cells present bFGF concentration dependent. ③EGF can improve the growth of NSCs, and promote them differentiate into neuron and glial cells; its effect of facilitating cell proliferation also presents concentration dependent. ④To elevate the efficacy of proliferation and differentiation of NSCs, allied application of bFGF and EGF is usual in NSCs culture. ⑤There is not a unified cognition to the effect difference of bFGF and EGF. CONCLUSION: bFGF and EGF have powerful effect to improve the proliferation and differentiation of NSCs; therefore, both of them are important neural somatomedin. Moreover, their effects present concentration dependent.

Objective To dynamic monitoring the changes of serum cortisol,adrenocorticotropic hormone (ACTH) in children with sepsis and servere sepsis,and to assess it's relationship with clinical features.Methods Thirty children with sepsis were enrolled in this study from Sep 2010 to Jan 2011 in our hospital,and were divided into severe sepsis group (n =10) and sepsis group (n =20).The serum cortisol and ACTH were analysed in acute and recovery period respectively in both two groups,and compared with 10 non-sepsis children as control group.Results In the acute period,the level of serum cortisol in severe sepsis group [ (33.97 ±6.83) μg/ml ] was significantly higher than those in sepsis group [ (26.30 ± 10.43) μg/ml]and control group [ ( 19.06 ± 6.91 ) μg/ml ] ( P ＜ 0.01 ) ; the level of serum ACTH in severe sepsis group [ (25.47 ± 9.41 ) pg/ml ] was significantly higher than those in sepsis group [ ( 15.52 ± 5.85 ) pg/ml ] and control group [ (9.16 ± 3.02 ) pg/ml ] ( P ＜ 0.01 ).Conclusion Stress response exists in the early period of sepsis,and the levels of serum cortisol and ACTH are increased significantly.The levels of serum cortisol and ACTH are positive correlation with the severity of diseases,and they could be used as serious index and a marker for evaluating prognosis in children with sepsis.

Objective To explore the eorrelafion factors of health promotion lifestyle of the elderly los-ing their land and sea estate. Methods Using the health value scale, health promotion lifestyle profile and the general conditions scale to investigate the health value, health promotion lifestyle and general conditions of 85 old people losing their land and sea estate in Dalian development area. Results There was no correlation between health value and health promotion lifestyle of the eldly, age, education degree, number of children and previous employment were rehted with the health promotion lifestyle. Conclusions There was distance be-tween their thought and actual health behavior of the elderly, community management personnels and med-ical workers should strengthen the concrete intervention in lifestyle, not simply relying on propaganda of the importance of health.

Objective To investigate the clinical characteristics,diagnosis,treatment of endometriosis in adolescent and to improve our knowledge,and to reduce misdiagnosis.Methods Clinical data of 17 patients with endometriosis in adolescents were analyzed retrospectively.Results Preoperative diagnosis is wrong in nine out of 17 cases.All patients underwent surgical operation and post-operative medcine treatment.Five cases have complicated genital tract anomalies.Four cases relapsed,good prognosis is expected in the other patients.Conclusion Clinical characteristics of endometriosis in adolescents are not positive.The treatment involves the surgical operation and medicine.

OBJECTIVE:To provide retrieval techniques for chemical and medical workers to mater the latest technology dynamic state.METHODS:The four basic retrieval methods of CA on CD(American Chemical Abstracts)were introduced,and of which,several classic logical combination retrieval techniques were exemplified in detail.RESULTS & CONCLUSIONS:The retrieval of CA on CD is characterized by convenience,rapidity,flexibility,multiform logical combination.Medical information worker should skillfully use the combination retrieval techniques and unceasingly explore the exemplification of these retrieval techniques.

Objective To analyse the clinical usage of Shenmai injection, promote the rational use of Shenmai injection. Methods 400 hospital medical records that used Shenmai injection in 2015 were collected and reviewed from hospital information system (HIS) by retrospective analysis method, aggregated and evaluated data by EXCEL. Results In 400 cases, 11 clinical departments used the Shenmai injection, mainly in cardiology of 347 cases(86.75%).The percentage of the non-standard clinical application of Shenmai injection was 84 cases (21.00%). The non-standardized rates of solvent dispensing was 287 cases (71.75%), and the specification incompatibility accounted for 105 cases (26.25%). There was no adverse drug reaction of Shenmai injection. Conclusion The clinical use of Shenmai injection is not yet standardized, which suggests that drugs should be strictly used in accordance with the instruction, in order to avoid risks of off-label use.

Objective To evalute the feasibility of a double hand allogroft to reconstuct the limbs'function. Methods A brain dead donor was chosen under the test of blood group in ABO and Rh,HLA match,PRA and the mixed leukocyte culture.The level of the transplantated hands was 5 cm proximal to the wrists The procedure of the allotransplantation was similar to that of the autologous replantation.The immunosuppressants were taken two days before the operation,in the operation and after the operation. The circulation,the vital signs and the rejection were under the supervision. Results The progress was satisfactory. No rejection was found postoperation.After 10 weeks the callus in both ends of radius and ulna was obvious.After 5 months sensation recovered.After 7 months the internal fixation(plates and screws) was removed and tenolysis was done. Now the recipient could use engrafted hands to wash face,make the bed,wear clothes,brush teeth,peel oranges,eat with a spoon,tie the shoelace slowly,pick up a telephoneor and use the conroller of Television. Conclusions With the immunosuppressive agents,the double hands allograft can survive.The growth rate of bone and nerve is faster than that of autologous replantation.
