The main obstacles and limitations on development of advanced life-rescuing information technology are identified based on analysis of existing information technology.The research ideas on digital information to replace analog information and response technology in lieu of new type life-rescuing information technology are putted forward,which combines RFID technology with biomedical engineering technology to research and design the life transponder that application bottleneck and advantage of the technique are analyzed.

Objective To observe neutrophil activation and protease imbalance in airway of children after foreign-body aspiration(FBA).Methods Bronchoalveolar lavage fluid(BALF) was obtained through fiberoptic bronchoscopy.The supernatant was assayed for the concentration of neutrophil elastase(NE) using enzyme-linked immunosorbent assay(ELISA) and elastase inhibition capacity(EIC)/free elastase activity using a colorimetric assay.The cell pellet were smeared for the expression of ?1-antitrypsin(?1-AT) using cellular immunohisto-chemistry and cytologic analysis by Wright-Giemsa stain.Results Percentage of neutrophil,concentration of NE and the expression of ?1-AT in BLAF group,pair group and pneumonia group significantly increased compared with that of control group(Pa0.05).The ratio of Lib NE in FBA,par and peumcria group was 30.3%,27.3% and 22.7%.Conclusions FBA induces similar airway neutrophil activation and protease imbalance to bacterial pneumonia.The contralateral airway showes the same change as the foreign body side.

Access of safe, effective, convenient and affordable medical and health care services to the people is set as the goal of public hospitals health services as stated in the "Guidelines for Public Hospitals Pilot Reform". Such a goal, however, can hardly be achieved by mechanism changes within the public hospitals. The input and output of public hospitals rely critically on such factors as the input mechanism, regional pattern of healthcare system, the economic and industrial conditions of the region,payment quota and payment approval procedures of medical insurance. This paper set off from the input compensation mechanism of public hospitals in China and analyzed the input and output characteristics of the hospitals. Furthermore, the paper proposed to establish an input compensation mechanism based on public welfare performance for such hospitals. This provided further reference for improving the management of public hospitals and building a public welfare-oriented operation mechanism of public hospitals.

Objective To evaluate the soft tissue profile in adults with unoperated isolated cleft palate. Methods Twenty patients older than 16 years(median age,18.4) with unoperated isolated cleft palate were enrolled.Soft tissue lateral cephalograms were traced and compared with those of cleft operated patients and class-Ⅰocclusion individuals.The results of various measurements were analyzed with ANOVA by SPSS11.5. Results In adults with unoperated isolated cleft palate,there was restriction at the top of the upper lip,and the antelabrum of upper lip and the lower lip were found normal. Conclusion The soft tissue profile in adults with unoperated isolated cleft palate exhibits almost the same characteristics as the corresponding hard tissue,and there is covering over effect of the soft tissue to some extent.

Cyclophosphamide (CPA) is the most common alkylating antineoplastic agent, as well as a strong immunosuppressant that is frequently applied to autoimmune diseases and organ transplantation. It is metabolized by cytochrome P450 oxidases (CYPs) to its active metabolite which played a critical role in therapy. CPA has serious and even fatal side effects, and its efficacy and adverse reactions are significantly varied among individuals. In this review, the association of the genetic polymorphisms in the metabolic enzymes and transporters involved in the disposition of CPA with the efficacy and adverse effects of CPA were summarized, thereby providing fundamental reference for further pharmacogenomic study of CPA.

Objective To explore the clinical value of squamous cell carcinoma associated antigen (SCC) and tumor specific growth factor (TSGF) in cervical carcinoma. diagnose. Methods The serum samples of SCC and TSGF were collected from 40 health volunteers, 56 cervical intraepithelial neoplasia (CIN) patients and 101 squamous cell cervical cancer patients. SCC and TSGF amount were measured by MEIA and biochemistry olorimetry method respectively, and were compared. Results The mean level of serum SCC and TSGF in the cervical cancer group was (6.95 ± 1.23) ng/mL and (81.0 ± 16.3)U/mL respectively, significantly higher than that in the CIN group and control group. The sensitivity and accuracy of combining SCC with TSGF in diagnosing cervical carcinoma were 91.1%and 87.4% respectively, both higher than allying SCC or TSGF alone. Conclusions SCC and TSGF levels are helpful in the diagnosis of cervix carcinoma. The combined determination can improve the sensitivity and accuracy of cervical carcinoma diagnose.

Objective To evaluate the effectiveness of biofeedback for anxiety patients by carrying out a Meta-analysis.Methods We searched CNKI,VIP,CBM(1989 to 2013) to identify relevant randomized-control trials applying biofeedback for anxiety patients.We used Review Management (RevMan) 5.0 software (provided by the Cochrane collaboration) to conduct Meta-analysis.Results We included 11 studies.Meta-analysis for the biofeedback group vs.the control group showed that biofeedback was significantly superior to control (SMD=-3.00,95％CI:-4.40～-1.61); Meta-analysis for the biofeedback plus drug group vs.drug group showed that biofeedback plus drug was significantly superior to drug (SMD=-1.33,95％CI:-1.82～-0.85).Conclusions We found evidence that biofeedback (applying alone or combined with drugs) is effective in improving anxiety symptom.But all the studies had methodological limitations,our conclusion needs further studies with strict design,high quality and consistent assessment tools to be expounded and proven.
