OBJECTIVETo study the expression and the role of heme oxygenase-1 (HO-1) and inducible nitric oxide synthase (iNOS) in preterm rats with hyperoxia-induced lung injuries.

METHODSSixty-four three-day-old preterm Sprague-Dawley rats were randomly assigned to a hyperoxia group (90% oxygen exposure) and a control group (room air exposure), with 32 rats in each group. After 3 days or 7 days of exposure, the lung activity of HO-1 and nitric oxide (NO) contents in bronchoalveolar lavage fluid (BALF), pulmonary histopathologic changes, and the cellular distribution and expression of HO-1 and iNOS in the lungs were measured.

RESULTSAfter 3 days and 7 days of exposure, the hyperoxia group showed acute lung injuries characterized by the presence of hyperaemia, red cell extravasation and inflammatory infiltration. The NO contents in BALF and the iNOS expression in the lungs increased significantly in the hyperoxia group compared with those in the control group 3 and 7 days after exposure. The expression of HO-1 in macrophages in the lungs increased significantly in the hyperoxia group compared with that in the control group 3 and 7 days after exposure. The NO contents in BALF and the iNOS and HO-1 expression in the lungs increased significantly 7 days after hyperoxia exposure compared with 3 days after hyperoxia exposure.

CONCLUSIONSiNOS and HO-1 levels in the lungs increase in preterm rats with hyperoxia-induced lung injuries, suggesting that iNOS and HO-1 may play roles in hyperoxia-induced pulmonary injuries.

OBJECTIVES: This cohort study investigated the correlation between Parkinson’s disease (PD) risk and chronic obstructive pulmonary disease (COPD) risk under particulate matter with an aerodynamic diameter ≤2.5 μm (PM2.5) exposure. METHODS: Data from the National Health Research Institutes of Taiwan were used in this study. The Environmental Protection Administration of Taiwan established an air quality monitoring network for monitoring Taiwan’s general air quality. COPD was indicated by at least 3 outpatient records and 1 hospitalization for COPD. After the implementation of age, sex, and endpoint matching at a 1:4 ratio, 137 patients and 548 patients were included in the case group and control group, respectively. Based on the 2005 World Health Organization (WHO) standards, monthly air particle concentration data were classified into the following 4 groups in analyses of exposure–response relationships: normal level, and 1.0, 1.5, and 2.0 times the WHO level ([concentration ≥2]×25 μg/m3×number of exposure months). RESULTS: A multivariate logistic regression revealed that the 1.0 and 1.5 WHO level groups did not significantly differ from the normal level group, but the 2.0 WHO level did (odds ratio, 4.091; 95% confidence interval, 1.180 to 14.188; p=0.038). CONCLUSIONS Elevated PM2.5 concentrations were significantly correlated with an increased risk of PD among patients with COPD. Furthermore, exposure to high PM2.5 levels can further increase the risk of PD.

OBJECTIVETo differentiate patients with esophageal cancer or premalignant lesions from the high-risk population for preliminary screening of esophageal cancer using a feature index determined by a computer-aided tongue information acquisition and processing system (DS01-B).

METHODSTotally, 213 patients diagnosed with esophageal cancer or premalignant lesions and 2,840 normal subjects were collected including primarily screened and reexamined, all of them were confirmed with histological examinations. Their tongue color space values and manifestation features were extracted by DS01-B and analyzed. Firstly, the analysis of variance was performed to differentiate normal subjects from patients with esophageal cancer and premalignant lesions. Secondly, the logistic regression was conducted using 10 features and gender, age to get a predictive equation of the possibility of esophageal cancer or premalignant lesions. Lastly, the equation was tested by subjects undergoing primary screening.

RESULTSSaturation (S) values in the HSV color space showed significant differences between patients with esophageal cancer and normal subjects or those with mild atypical hyperplasia (P<0.05); blue-to-yellow (b) values in the Lab color space showed significant differences between patients with esophageal cancer or premalignant lesions and normal subjects (P<0.05). Logistic regression analysis showed that the computer-aided tongue inspection approach had an accuracy of 72.3% (2008/2776) in identifying patients with esophageal cancer or premalignant lesions for preliminary screening in high-risk population.

CONCLUSIONComputer-aided tongue inspection, with descriptive and quantitative profile as described in this study, could be applied as a cost- and timeefficient, non-invasive approach for preliminary screening of esophageal cancer in high-risk population.

Objective To study the integrated monitoring program regarding mouse and plague, hemorrhagic fever of renal syndrome(HFRS)and leptospirosis. Methods Integrated monitoring plan was used. A designated office coordinated 5 departments' actions within the Zhejiang Provincial Center for Disease Control and Prevention(CDC). Cage-trapping method was conducted to monitor the density of mice from June to October, respectively. Results Lishui municipal CDC had finished the integrated monitoring program on mouse and mouse-borne disease while the Longyou CDC had finished the field investigation, using the integrated monitoring program.Specimens were sent to provincial CDC. The integrated monitoring program needed more number of personnel and better coordination. Lishui reported 3 leptospirosis cases and 58 HFRS cases in 2009,with the incidence rates as 0.13 and 2.44 per 100 000, respectively. Longyou reported 2 leptospirosis case and 1 HFRS cases in 2009, with the incidence rates as 0.49 and 0.25 per 100 000, respectively.Lishui and Longyou had no plague case. Lishui caught 91 mice in 2009 and the density was 4.17%.Longyou caught 37 mice in 2009, with the density as 1.18 percent. Most mice caught from Lishui were Apodemus agrarius and the next was Mus musculus. In Longyou the Rattus tanezumi ranked the first, followed by Apodemus agrarius. The positive rate of HFRS antigen in Lishui and Longyou were 10.42% and 4.59% respectively. The positive rate of HFRS antibody in Longyou was 3.70%. The culture positive rate of leptospirosis in mouse renal of Lishui and Longyou were 0 and 0.98%respectively. The culture positive rate of leptospirosis in pig renal, duck renal, frog renal and cattle urine of Longyou was 0. The culture positive rate of leptospirosis in duck blood of Longyou was 80%.Conclusion The integrated monitoring program on mouse and mouse-borne disease seemed to be feasible and could promote the integrated surveillance and control program on mouse and mouse-borne diseases in China.

OBJECTIVETo study the clinicopathologic features and prognostic factors of Chinese patients with mantle cell lymphoma.

METHODSOne hundred and two cases of mantle cell lymphoma occurring in Chinese patients were studied by light microscopy and immunohistochemistry. The follow-up information was also analyzed. The cases were classified as mantle zone, nodular or diffuse patterns and as typical or blastoid variants. Age, Ann-Arbor staging, B symptoms, hematologic parameters, histologic variants, mitotic index and immunophenotype were assessed for possible prognostic implication.

RESULTSThe median age of the patients was 59 years (range: 30 to 79 years) and the male-to-female ratio was 2.92:1. Seventy-one patients (87.65%) presented with advanced stage disease (Ann Arbor stage III to IV). B symptoms were present in 45.45% of patients. The commonest site of involvement was lymph node (100%). The other involved sites included bone marrow (64.44%), spleen (63.16%), Waldeyer's ring (31.25%), peripheral blood (29.41%), liver (22.64%) and gastrointestinal tract (14.71%). All cases expressed B-cell markers but were negative for T-cell marker. Majority of cases were positive for cyclin D1 (94.12%) and CD5 (71.43%). Blastoid variant accounted for 24.51% of cases. Amongst the 68 cases with follow-up data available, the median survival was 10 months. Parameters associated with shorter survival included diffuse pattern, blastoid variant, high mitotic index, high proliferative activity and presence of bone marrow involvement.

CONCLUSIONSThe clinicopathologic features and prognostic factors of mantle cell lymphoma occurring in Chinese are similar to those in Caucasians. Diffuse pattern, blastoid variant, high mitotic index, high proliferative activity and involvement of bone marrow indicate poor prognosis.

OBJECTIVE: To review the surgical treatment for reconstructing hypopharynx and cervical esophagus after hypopharyngo-oesophagectomy, and to evalue its efficacy. METHODS: Different methods were adopted to reconstruct the hypopharynx and cervical esophagus among 25 cases, including 14 cases of carcinoma of the hypopharynx and 11 of carcinoma of hypopharynx and cervical esophagus. In accordance with the standard of the International Union Against Cancer in 1997, the 25 cases were divided into different clinic stages, among which 5 were in T(2)N(0), 2 in T(2)N(1), 4 in T(3)N(0), 3 in T(3)N(1), 7 in T(4)N(1) and 3 in T(4)N(2). Treatment protocol was as follow: Pure operation for 5 cases, re-operation after radiotherapy for 2 cases, operation plus radiotherapy for 18 cases, laryngeal conservation operation for 8, and neck dissection for 21 cases. Reconstruction was done by using free jejunal transplantation, gastric pull-up, the laryngotracheal flap, and myocutaneous flap. RESULTS: After the reconstruction, 3 cases of free jejunal graft and gastric pull-up, 4 of laryngotracheal flap recovered oral fleeding within 2 weeks. No serious complications occurred. After 18 cases underwent the myocutaneous flap reconstruction, no complications occurred in 10 patients, but there were different complications in 8 cases, including pharyngocutaneous fistula (6 cases), haryngoesphageal stenosis (7 cases), and pectoralis major myocutaneous flap necrotic (1 case). The 3-year survival rate was 38.9% (7/18). CONCLUSION Reconstruction with free jejunal graft, gastric pull-up, and laryngotracheal flap constitutes is a safe and reliable method to restore the continuity of the upper digestive tract after pharyngo-laryngo-oesophagectomy. After the reconstruction with myocutaneous flap, there is high incidence of pharyngocutaneous fistula and haryngoesophageal stenosis.
