OBJECTIVETo explore the relationship between ulcerative colitis (UC) and lung injuries by assessing their clinical manifestations and characteristics.
METHODSFrom July 2009 to April 2012, 91 UC patients presenting to Longhua Hospital who met the established inclusion and exclusion criteria were enrolled in this retrospective study. According to the scores of disease activity index, the patients were divided into the mild, moderate, and severe groups. Meanwhile, the records of pulmonary symptoms, chest X-ray image, and pulmonary function were reviewed.
RESULTSSixty-eight (74.7%) patients had at least 1 pulmonary symptom, such as cough (38.5%), shortness of breath (27.5%), and expectoration (17.6%). And 77 (84.6%) had at least 1 ventilation abnormality. Vital capacity value was significantly lower in the severe group than that in the mild group (91.82%±10.38% vs. 98.92%±12.12%, P<0.05).
CONCLUSIONSLung injury is a common extraintestinal complication of UC. According to the theory in Traditional Chinese Medicine that the lung and large intestine are related, both the lungs and large intestine should be treated simultaneously.

BackgroundIdiopathic epiretinal membranes(ERMs) is a common eye disease condition that leads to progressive decline of visual acuity. Studying the risk factors relating to this disease will shed light on its pathogenesis and allow opthalmologists to screen the affected individuals among the high-risk population and prepare for prevention and management strategies. ObjectiveThis survey was to investigate the risk factors of idiopathic ERMs in the population undergoing routine health check-ups. MethodsThe clinical data of idiopathic ERMs was obtained from the population of routine health check-ups in Peking Union Medical College Hospital from November 2009 to October 2010. The examination outcomes were compared between the individuals with and without idiopathic ERMs. The demographic and clinical factors associated with idiopathic ERMs were analyzed and assessed using univariate and multivariate logistic regression analyses. Result A total of 27 400 people were included in the survey and idiopathic ERMs were diagnosed in 76 cases. No obvious eye complaint was obtained from the idiopathic ERMs. The number of people affected with idiopathic ERMs was 12 ( 12/11 659 ) in the below 40 years group, 21 (21/4595) in the 51-60 years group and 32 (32/2544) in the over 60 years group. Hypertension, diabetes, diedyslipidemia, renal function insufficiency ,and cataract were found in 42% ,5% ,66% ,6% and 8% of the patients, respectively. The univariate logistic regression analyses revealed that significant correlations were found between age,hypertension,hyperlipidemia and history of cataract( P<0. 01 ). Multivariate regression models showed that the risk of idiopathic ERMs increased in age of 51-60( OR=2. 5,95% CI:1. 2-5.4,P=0.02) and over 60 years( OR =7.3,95% CI:3.4-15.6 ,P<0.01 ) and patients suffering from hyperlipidemia ( OR--2. 1,95% CI:1. 3-3.5, P<0. 01 ). ConclusionsOver the age of 50 years and hyperlipidemia are primary risk factors of idiopathic ERM.

To study the effects of Qingdai compound on proliferation and apoptosis of K562 cells, as well as the expression of bcr/abl and JWA mRNA, K562 cells were treated in culture with different concentrations of Qingdai compound (2.5, 5, 7.5, 10 and 20 mg/ml) and harvested at 24 hours. Then morphological changes were observed by light microscopy (LM); expressions of bcr/abl and JWA were detected with semi-quantitative RT-PCR. The results showed that morphological changes were observed as the increment of the Qingdai compound concentration. Inhibition effects on proliferation and apoptosis in K562 cells were seen. A concentration-dependent decreases were found in bcr-abl and JWA mRNA expression of K562 cells. Qingdai compound partially inhibited proliferation and induced apoptosis of K562 cells. Expressions of both bcr/abl and JWA, which took part in cell proliferation and apoptosis, were down-regulated in a dose dependent manner. In conclusion, Qingdai compound can partially inhibit the expressions of bcr/abl and JWA genes in K562 cells, and the clinical effect of Qingdai compound on CML may be associated with apoptosis of leukemic cells.

To investigate the antitumor activities of the immunoconjugates composed of anti-type IV collagenase monoclonal antibody Fab' fragment and lidamycin (LDM) prepared with different linkers. The immunoconjugates were prepared by linking Fab' to lysine-69 of LDM apoprotein by SPDP, LCSPDP, SMBS or SSMPB as the intermediate drug linkers. Immunoreactivities of the conjugates were determined by ELISA. The cytotoxicities of the conjugates were examined by clonogenic assay. In vivo antitumor effects of the conjugates were evaluated in nude mice bearing subcutaneously implanted HT-1080 tumor. ELISA assay showed that the conjugates retained part of the immunoreactivity of 3G11 against the antigen. The cytotoxicities of the Fab'-SMBS-LDM and Fab'-SSMPB-LDM to HT-1080 cells were significantly potent, compared with Fab'-SPDP-LDM, Fab'-LCSPDP-LDM and free LDM. In animal models at the same condition, free LDM, Fab'-SPDP-LDM and Fab'-LCSPDP-LDM inhibited the growth of HT-1080 tumor by 70.9%, 74.8% and 72.3%, while Fab'-SMBS-LDM and Fab'-SSMPB-LDM reached 78.0% and 87.7%, respectively. The median survival time of the mice treated with free LDM, Fab'-SPDP-LDM and Fab'-LCSPDP-LDM were prolonged by 71.9%, 82.2% and 107.5%, respectively, compared with that of untreated group. Whereas, the median survival time of Fab'-SMBS-LDM and Fab'-SSMPB-LDM were prolonged by 145.2% and 165.8%, respectively, indicating that Fab'-SSMPB-LDM was more effective than Fab'-SMBS-LDM in tumor suppression and life span prolongation. Fab'-SSMPB-LDM has more marked selective antitumor efficacy and lower toxicity, and might be a novel candidate for cancer therapy.

Objective To explore the plague epidemical trend of nearly a 10 years data in Qinghai province to provide basis for making the prevention and control measures. Method The regional distribution and time distribution of animal and human plague, monitoring and plague foci of survey data in Qinghai from 2001 to 2010 were analyzed with Excel software 2003. Results In Qinghai province, a total of 167 strains of Yersinia pestis were isolated from infected animals and insects in 10 years. Yersinia pestis was mainly distributed in Wulan,Delinha, Geermu, and Tianjun, along the Qinghai-Xizang railway. Human plague was occurred every year from 2001 to 2010 except 2002, 2007, 2008, and 2010. In the 10 years, there were 37 plague cases and 16 of these cases died, the mortality was 43.24%. The plague cases were mainly distributed in Nangqian, Qumalai, Chenduo,Zhiduo, Xinghai, Tongde, Tianjun, Wulan and Qilian. And these cases were found mostly in the period from May to October, especially in the period from August to October. Major clinical type of the plague cases was lung-type (62.16%,23/37). Conclusions The plague epidemic situation in Qinghai province is still severe, animal plague occurred year after year, and human plague outbreaks occasionally. Monitoring and early warning in the key areas should be strengthened, and the comprehensive measures of plague prevention and control should be carried out to reduce the incidence and prevalence of plague.
