Objective To investigate the efficacy of centrally fixed eyeball for assessment of the depth of anesthesia in premature infants undergoing outpatient fundus examination. Methods Fifty eight premature infants undergoing examination of fundus of eyes were enrolled in this study. Their gestational age (from the first day of last menstruation period to birth) + after birth age (from birth to the day when examination of fundus of eyes was performed) = 44-64 weeks. The patients were randomly divided into 2 groups: Ⅰ group body movement (group M, n = 27) and Ⅱ group centrally fixed eyeball (group E, n = 31). Anesthesia was induced and maintained with isoflurane inhalation. The patients were breathing spontaneously. The eyelids were kept open with speculum after induction of anesthesia. The EC50 of sevoflurane concentration which could inhibit body movement or make eyeballs centrally fixed was determined by up-and-down sequential experiment. The initial isoflurane concentration was 3% in both groups. Each time the isoflurane concentration was increased/decreased by 0.5 %. 95 % confidence interval (CI) was calculated. The lowest SpO2, respiratory rate and coughing during maintenance of anesthesia were recorded. Results The EC50 of sevoflurane (95% CI) was 2.9% (2.2%-3.6%) in group M and 3.4%(2.6%-4.6%) in group E. Examination was successfully completed in all patients. No respiratory depression and coughing occurred during examination and no vomiting and coughing were observed during feeding at 1 h after recovery from anesthesia. No body movement occurred in 15 patients whose eyeballs were centrally fixed in group E. Conclusion Centrally fixed eyeball can be used as sign of appropriate depth of anesthesia for fundus examination in premature infants.

Through defining the connotation of division and cooperation among medical institutions, this paper introduces the current status for division and cooperation among medical institutions of Britain, Germany, Singapore and USA. The advantages include excellent general practices, optimal health resource allocation, effective first treat-ment in community health facilities, and effective two-way referral. We analyzed the influence of some new policies on the division and cooperation among medical institutions such as medical association, managed care and the General Practices’ service contract. This provided a lot of experience and revelations, including the dynamics to promote the division and cooperation, the separation of outpatient services and inpatient services, privatization of primary medical institutions, division and cooperation between medical institutions and nursing, rehabilitation institutions, distinguis-hing the division and cooperation from hospitals alliance, and division and cooperation among medical institutions can not resolve the all issues in the medical care supply system.

ObjectiveTo evaluate prognostic factors and the surgical results of pulmonary carcinoid tumors.Methods We retrospectively reviewed the medical records of 62 patients who were diagnosed as pulmonary carcinoid tumors between January 2000 and October 2010 at Department of Thoracic Surgery,Shanghai Chest Hospital.The following information was available for each of the 62 patients:age,sex,pathological type,and TNM stage.ResultsThere were no operative death.The 3-year and 5-year survival rates after surgery were 92.1％ and 77.8％,respectively.Of the 62 patients,42 were diagnosed as typical carcinoid tumor,and among them,4 patients (8.3％) had lymph node metastases.Their 3-year and 5-year survival rates were 97.8％ and 94.7％,respectively.The remaining 20 patients were diagnosed as atypical carcinoid tumor,and among them,6 patients (37.5％) had lymph node metastases.Their 3-year and 5-year survival rates were 84.4％ and 58.8％,which were statistically significant compared with typical carcinoid tumor( P =0.0047 ).There was significant difference in survival rate between the patients with lymph node metastases and the patients without lymph node metastases (P =0.0048).CondusionThe main risk factors affecting survival rate of those patients who were diagnosed as pulmonary carcinoid tumors were pathological types and lymph node metastases.

Objective To investigate the effect of high mobility group box-1 protein (HMGB1) on cytokine expression in splenic dendritic cell (DCs). Method DCs isolated from the spleens of male Wistar rats were seed-ed on 96-well (1×10s cells/well) cell culture plates, and the cells were stimulated with HMGB1 for various length of time or in different concentrations. (1) The time-dependent response between HMGB1 and tumor necrosis factor-α(TNF-α) as well as interleukin-12 (IL-12) gene/protein expressions: 24 wells of DCs were dividedly into six groups including 24 h-normal controls (n=4), 48 h-normal controls (n=4), 72 h-normal controls (n=4), and 24 h-HMGB1 treated group (n=4), 48 h-HMGB1 treated group (n=4) as well as 72 h-HMGB1 treated group (n=4), respectively. Among three HMGB1-treated groups, DCs were stiraulated by 1 μg/mL HMGB1. DCs were denatured in cell culture plates to determine gene expression of IL-12 as well as TNF-α, and supernatants were harvested to determine Il-12 as well as TNF-α protein levels. (2) The dose-dependent response between HMGB1 and TNF-α as well as IL-12 gene/protein expressions: 16 wells of DCs were dividedly into four groups in-cludingnormal controls (n=4), 0.1 μg/mL HMGB1 treated group (n=4), 1 μg/mL HMGB1 treated group (n =4), and 10 μg/mL HMGB1 treated group (n=4), respectively. After stimulated for 48 h, DCs were dena-tured in cell culture plates to determine gene expression of IL-12 as well as TNF-α, and supernatants were harvest-ed to determine IL-12 as well as TNF-α protein levels. Total RNA was extracted from cells using the single-step technique of acid guanidinium thiocyanate-chloroform extraction according to the manufacturer' s instruction (Promega, Madison, WI). mRNA for TNF-α and IL-12 were quantified by SYBR Green two-step, real-time re-verse transeription-polymerase chain reaction taking glyceraldehyde-3-phesphate dehydrogenase (GAPDH) as an internal standard. Levels of IL-12 and TNF-α in cell culture supernatants were determined with ELISA, strictly fol-lowing the protocols provided by the manufacturer. Data were analyzed with a one-way ANOVA. A P-values <0.05 were considered statistically significant. Results After stimulation with 1 μg/mL HMGB1, IL-12 and TNF-α protein and gene expressions in rat splenic DCs were markedly up-regulated at 24 h to 72 h (P<0.05 or P<0.01), and the expression levels of IL-12 and TNF-α peaked at 48 h (P<0.01). When DCs were cultured in the presence of 0.1 μg/mL, 1 μg/mL, and 10 μg/ml HMGBI for 48 h, expressions of IL-12 and TNF-α were also significantly up-regulated (P<0.01), and values of these cytokines were highest in 1 μg/mL HMGB1-treated group (P<0.01). Conclusions These data suggest that HMGB1 appears to be a potential immunostimulatory signal that induced DC maturation, and HMGB1 stimulation can result in marked up-regulation of IL-12 as well as TNF-α synthesis and release in splenic DCs.
