Objective To evaluate the relationship between body mass index (BMI) and malignant lymphoma by means of Meta-analysis. Methods Such databases as Web of Science, PubMed, EBbase, CNKI, Wanfang, VIP and CBM were searched from the date of their establishment to April 2011 to collect the case control studies on the relationship between BMI and malignant lymphoma. Two researchers independently selected studies, extracted data and assessed the quality according to the inclusive and exclusive criteria, and then conducted Meta-analyses by using RevMan5.0 software for heterogeneity test and pooled OR calculation. Results Seven case control studies involving 8416 malignant lymphoma patients and 14760 other patients were included. The quality of all studies scored 4, indicating reliable quality. Meta-analyses of the low BMI, overweight and obesity population were OR=0.8, 95%CI 0.79 to 0.95, P=0.003; OR=1.04, 95%CI 0.98 to 1.11, P=0.16; and OR=1.22 95%CI 1.04 to 1.43, P=0.01, respectively. The stratified Meta-analysis on histological subtypes showed that obesity was associated with a significantly increased risk of diffuse large B cell lymphoma (OR=1.33 95%CI 1.18 to 1.50, Plt;0.000 01), but was not associated with the follicular lymphoma or small lymphocytic lymphoma/chronic lymphocytic leukemia. Conclusion These findings demonstrate that low BMI is associated with the decrease of malignant lymphoma, and obesity is an increasing risk of malignant lymphoma, especially, the diffuse large B cell lymphoma.
Objective We aimed to describe the prevalence of metabolic syndrome, its epidemiological characteristics, and to analyse the relationship of waist-to-hip ratio (WHR) and body mass index (BMI) with metabolic syndrome (MS) among staff at Southeast University. Methods The data from the overall physical examination of 1979 staff were analyzed.Results The crude prevalence of MS were 21.7%,26.4% and 14.2% in the whole population, men and women respectively. The standardized rates were 14.7%,19.0% and 9.4%. The prevalence of MS in men was significantly higher than that in women(Plt;0.05). Both abdominal obesity and visceral obesity were positively correlated with the prevalence of MS(r=0.295, 0.248, P=0.000). Conclusion The prevalence of MS among staff of Southeast University has shown a significant increase in 2006. WHR and BMI are both correlated with the prevalence of MS.
Objective To investigate the relationship between adipocyte fatty acid binding protein ( A-FABP) and obstructive sleep apnea hypopnea syndrome ( OSAHS) . Methods A total of 120 patients were recruited and underwent polysomnography. The groups were allocated according severity of OSAHS and obesity. Plasma A-FABP ( ng/mL) levels were measured by ELISA. The associations between A-FABP and AHI, BMI, LSaO2 , MSaO2 , neck collar, waist /hip ratio, insulin resistance index were analyzed. Results Plasma A-FAPB levels were significantly higher in the OSAHS group than in the non-OSAHS group of same weight, independent of age and gender. In the non-OSAHS group and the severe OSAHS group, plasma A-FABP levels of obesity persons were significantly higher than those without obesity, independent of age and gender. Plasma A-FAPB level was positively correlated with AHI, BMI, insulin resistance index, neck collar, SLT90% , and waist/hip ratio, but negatevely correlated with LSaO2 and MSaO2 in the OSAHS group. In the non-OSAHS group, plasma A-FAPB level was positively correlated with BMI and insulin resistance index. Conclusions Plasma A-FABP level is higher in patients with severe OSAHS. Plasma A-FABP level is positively correlated with BMI and insulin resistance index both in OSAHS and non-OSAHS patients.
Objective Chronic obstructive pulmonary disease( COPD) is highly heterogeneous. In theory, the patients with same clinical manifestations, treatment response and prognosis can be classified into one phenotype, which may have same biological or physiological mechanisms. In this study the profiles of patients with COPD including body mass index( BMI) , Goddard score, fractional exhaled nitric oxide( FeNO) were analyzed in order to find some special phenotypes.Methods Patients with COPD at stable stage in Ruijin Hospital from May 2011 to February 2012 were evaluated with COPD assessment test ( CAT) in Chinese version, St. George’s Respiratory Questionnaire( SGRQ) , hospital anxiety and depression( HAD) rating scale, pulmonary function test, and 6-minute walking test ( 6MWT) . Baseline data was collected including height, weight, drug use, times of exacerbation, etc. Results A total of 126 patients were recruited. The patients with low BMI had poorer quality of life, lower FEV1 , poorer diffusion function, and higher Goddard score, and was easier to develop anxiety and depression. The patients with high BMI had lower oxygen saturation at rest. We failed to define a certain kind of phenotype according to FeNO. The patients of emphysema phenotype( assessed by Goddard score) had lower BMI, decreased lung diffusion capacity, and poorer quality of life. Conclusion The study can define COPD patients into some special phenotypes( low BMI and emphysema phenotype) , but failed to define a certain kind of phenotype according to FeNO.
Objective To analyze the influence of the body mass index (BMI) and age on deep vein thrombosis (DVT) after the total hip arthroplasty(THA) or total knee arthroplasty(TKA) in Chinese patients who received prophylactic treatment for DVT. Methods We used a randomized clinical case-control study. From April 2004 to August 2004, weperformed THA and TKA for 95 patients (128 hips and knees). There were 27 men and 68 women with an average age of 60 years (range, 23-78) at surgery, and withan average BMI of 25.88 kg/m2 (range, 14.34-40.39) before surgery. All the patients were given low-molecular-weight heparin for 7-10 days pre-and postoperatively to prevent DVT. Color Doppler ultrasonography was used to detect DVT of bilateral lower extremities in all the patients before operation and 7-10 days after operation.The patients were divided into 4 groups according to their BMI:the non-obese group (BMI≤25.00 kg/m2), the overweight group (BMI, 25.01-27.00 kg/m2), the obese group (BMI, 27.01-30.00 kg/m2), and the morbidly obese group (BMIgt;30.00 kg/m2); and they were also divided into 4 groups according to their ages (≤40, 4160, 61.70, gt;70 yr) so as to analyze the influence of the BMI and age on DVT. Results The total incidence ofDVT in all the patients was 47.4% (45/95) and the incidence of proximal DVT was 3.2%. Forty-five patients had DVT and 50 patients had no DVT. The average BMI of the patients with DVT was significantly higher than that of the patients with no DVT (Plt;005). The overweight, obese, and morbidly obese patients had an odds ratio of 7.04, 4.8,and 9.6 for DVT compared with the nonobese patients (P＜0.05); but the obese group had a less risk than the other 2 groups.The 41-60, 61-70, and gt;70-year-old patients had an odds ratio of 24.0, 38.2, and 24.4 for DVT compared with the ≤40year-old patients (P＜0.05). Conclusion Obesity (BMIgt;25 kg/m2) and an increasing age (gt;40 yr) are identified as statistically significant risk factors for DVT after THA or TKA, and patients aged 61-70 years are more likely tohave DVT than the other patients. We should pay more attention to those obesity and aged patients when they are undergoing the total joint replacement, and we should give them enough prophylaxis and closely observe the symptoms in their bilateral lower extremities after operation, taking ultrasonography or venography to check DVT if necessary, so that we can give them prompt treatment and prevent fatal pulmonary thromboembolism.

MethodsA survey, including height, weight, blood pressure and pulse, was carried out in a general population of Chengdu. A total of 711 subjects (average age: 63.28±6.25 years; male: 57.8%) were recruited by random sampling method. Results：The proportion of overweight and obesity was about 45%. The hypertension prevalence rate was significantly positively correlated with BMI (Plt;0.01), and that was also seen in the level of SBP and DBP for the female (Plt;0.05). In logistic regression analysis adjusting for age, gender, waist, uric acid, the standardized OR for higher BMI (≥28.0 kg/m2) as a risk factor of hypertension was 5.140. Conclusion：The proportion of overweight and obesity was great in Chengdu area. BMI can affect the prevalence rate of hypertension and the level of blood pressure.
ObjectiveTo investigate the nutritional risk, incidence of malnutrition, and clinical application of nutrition support in hospitalized patients with gastric cancer by the nutritional risk screening (NRS) 2002 score summary table. MethodsFrom June 2009 to February 2010, nutritional risk screen and application of clinical nutritional support were carried out in the hospitalized patients with gastric cancer in this hospital. Nutritional risk was assessed case-by-case according to the severity of illness, nutritional status 〔including body mass index (BMI), recent changes in body weight and eating〕 and patients age. NRS ≥3 was accepted as nutritionally at-risk, while NRS lt;3 no nutritional risk; BMI lt;18.5 kg/m2 (or albumin lt;30 g/L) combined with clinical conditions was judged to be malnourished. Results Three hundreds and eighty-six patients were included, 329 of which completed the NRS2002 screening. One hundred and sixty-five patients (50.15%) were at nutritional risk, while another 164 (49.85%) were no nutritional risk. Malnutrition was found in 57 patients (17.33%). By gender, male malnourished patients and nutritionally at-risk patients were accounting for 16.45% (38/231) and 48.05% (111/231) respectively, while female nutritionally at-risk patients and malnourished patients were accounting for 55.1% (54/98) and 19.39% (19/98) respectively, 72.04% (237/329) of the screened patients accepted clinical nutrition support, among which, 115 patients were at nutritional risk, accounting for 69.70% in that group, and 122 patients were no nutritional risk, accounting for 74.39% in that group. ConclusionsThe incidences of malnutrition and nutritionally at-risk in hospitalized gastric cancer patients are high. And irrationality of clinical nutrition support exists. Evidence-based guidelines are required to improve the nutritional status of support.
