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.

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.

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.

microRNAs (miRNAs) are short non-protein-coding RNAs,which play important roles in the cell proliferation,differentiation,apoptosis,as well as activation of oncogenic and antioncogenic signals.Researches show that the abnormal expressions of miRNAs are closely related to the tumorigenesis,histological type,diagnosis,treatment and prognosis of lung cancer.So miRNAs may be the most potential and promising therapeutic targets for lung cancer.

Objective To investigate the effects of eye movement desensitization and reprocessing (EMDR) versus cognitive behavior therapy (CBT) for treating adult posttraumatic stress disorder (PTSD) .Methods A total of 81 patients with PTSD con‐forming to the including standard were randomly allocated to the EMDR group ,CBT group ,and control group ,27 cases per group . The PTSD symptoms ,anxiety and depression moods in 3 groups were assessed before and after treatment by adopting the Clinician‐administered PTSD Scale (CAPS) ,Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) .Results The drop‐out rates were 29 .63% for the EMDR group ,7 .41% for the CBT group and 7 .41% for the control group respectively ;the re‐experience symptoms score of CAPS in the EMDR group was lower than that in the CBT group with statistical difference (P=0 . 036) .Conclusion Both EMDR and CBT are the effective psychological therapeutic method ,EMDR has more effective than CBT in the reproving the re‐experience symptoms of PTSD .The future studies should pay more attention to the application of stabilization technologies for reducing the dropout rate of EMDR .
