The study investigated the hospitalization cost in patients with AECOPD and the associated factors. Methods A multi-center, retrospective study was conducted in the four hospitals in Beijing including two level III hospitals and two level II hospitals. Patients with AECOPD admitted to the hospitals between January and December in 2006 were enrolled. The hospitalization cost and its relationship with disease severity and treatment were analyzed. Results Totally 439 patients were enrolled with 294 men （67.0%） and a mean age 73.4 years. The mean hospital stay was 20.7 days. A total of 204 patients （46.5%） had respiratory failure, 153 （34.9%） with cor pulmonale, 123 （28.0%） with coronary artery disease, 231 （52.6%） with hypertension, 70 （15.9%） with cerebrovascular disease and 32 （7.3%） with renal failure. The percentage of drug cost to total cost was the highest （71.2%）, followed by laboratory cost （16.7%）, therapy cost （9.7%）, oxygen cost （7.3%）, radiology cost （4.5%）, examination cost （4.5%）, bed cost （4.1%）. Correlation analysis showed that cost was positively correlated with age, hospitalization days, co-morbidities such as respiratory failure and cor pulmonale, hypertension. Three hundred and twenty-one patients were further analyzed. The hospitalization cost increased in patients with non-invasive ventilation （P〈0.01）, invasive mechanical ventilation （P〈0.01）, ICU stay （P〈0.01）, antibiotics （P〈0.05）, systemic steroids （P〈0.01）, and poor prognosis （P〈0.05）. Correlation analysis showed that the hospitalization cost was negatively correlated with percentage forced expiratory volume in 1 second （FEV1%） （r=-0.149, P〈0.05）, pH （r=-0.258, P〈0.01）, and PaO2 （r=-0.131, P〈0.05）, positively correlated with PaCO2 （r=0.319, P〈0.01）, non-invasive positive pres展开更多

METHODS： Human MK and tMt（ plasmids were constructed and expressed in BGC823 （a gastric adenocarcinoma cell line） to investigate the effect of over-expressed MK or tMK on cell growth and turmorigenesis in nude mice. RESULTS： The growth of MK-transfected or tMK- transfected cells was significantly increased compared with that of the control cells, and tMK-transfected cells grew more rapidly than MK-transfected cells. The number of colony formation of the cells transfected with MK or tMK gene was larger than the control cells. In nude mice injected with MK-transfected or tMK-transfected cells, visible tumor was observed earlier and the tumor tissues were larger in size and weight than in control animals that were injected with cells without the transfection of either genes. CONCLUSION： Over-expressed MK or tMtC can promote human gastric cancer cell growth in vitro and in vivo, and bMK has greater effect than MK. tMK may be a more promising gene therapeutic target compared with MK for treatment of malignant tumors.展开更多

Their coexistence is referred to as the overlap syndrome. They are both related to pulmonary hypertension (PH) development. This study investigated the effects of OSA on PH in patients with COPD and the associated factors. Methods: Consecutive patients with stable COPD were recruited for an observational cross-sectional study from September 2016 to May 2018 at Peking University Third Hospital. In total, 106 patients with COPD were enrolled and performed home portable monitoring and echocardiography. OSA was defined by an apnea hypopnea index (AHI)>10 events/h. Based on OSA absence or presence, patients were divided into the COPD with OSA and COPD without OSA groups. Factors affecting pulmonary artery pressure (PAP) and PH were identified using univariate analysis and logistic regression models. Results: In the 106 patients with COPD, the mean age was 69.52 years, 91.5% were men, and the mean forced expiratory volume in 1 s (FEV!) percentage of predicted was 56.15%. Fifty-six (52.8%) patients with COPD were diagnosed with OSA, and 24 (22.6%) patients with COPD were diagnosed as PH. Compared with COPD without OSA group, the median PAP in COPD with severe OSA group increased by 5 mmHg (36.00 [26.00-50.00] mmHg vs. 31.00 [24.00-34.00] mmHg, P = 0.036). COPD with percent of night-time spent with oxygen saturation below 90%(T90)> 10% group had higher PAP than COPD with T90 < 1 % group (36.00 [29.00-50.00)] mmHg vs. 29.00 [25.50-34.00] mmHg, F = 7.889, P = 0.007). Univariate analysis revealed age, FEVi% predicted, T90, and Charlson index had statistically significant effects on PH. Multiple regression analysis showed a significant and independent effect of both FEVj% predicted (odds ratio [OR]= 3.46;95% confidence interval [Cl]: 1.15-10.46;P = 0.028) and AHI (OR = 3.20;95% Cl: 1.09-19.35;P = 0.034) on PH. Conclusions: Patients with COPD with OSA are more susceptible to PH, which展开更多

METHODS: Clinical screening of colonoscopy was performed for 2196 patients aged 60-90 years old according to the protocol,and 1740 of them (79.2%) were followed-up. RESULTS: Colorectal cancer was found in 52 patients, and the detectable rate was 2.4%. Among them, 19 were diagnosed as early colorectal cancer, accounting for 36.5% of the detected colorectal cancer. Among the followed-up patients, early colorectal cancer was found in 9, accounting for 45.0% of the detected colorectal cancer. The resectable rate and 5 years survival rate of colorectal cancer were 97.7% and 80.9% respectively. The incidence of complication was 0.05%, and the successful rate of cecum intubation was 98.9%. CONCLUSION: Colonoscopic screening and follow-up of the elderly for colorectal cancer and pre-cancerous lesion (adenomatoid polyp) can increase the detectable rate of early colorectal cancer and improve its prevention and treatment.展开更多
