In order to provide scientific basics for exploitation and sufficient application of Dendrobium officinale leaves resources, the phenol-sulfuric acid method was applied to determine the polysaccharide content. The monosaccharides were derivated by PMP and the derivatives were identified by HPLC-DAD-ESI-MS(n) and the contents of mannose and glucose were determined simultaneously. Similarity evaluation system for chromatographic fingerprint of traditional Chinese medicine (2004A) was employed to generate the mean chromatogram and similarity analysis of the samples was carried out. The results demonstrated that polysaccharide content, monosaccharide compositions and composition ratio had an obvious difference between stems and leaves. The polysaccharide content of stems was higher than that of leaves. Monosaccharide composition in leaf was significantly different from that in stem. The polysaccharide from stems was composed of mannose and glucose, however the polysaccharide of leaves was acid heteropolysaccharide and was mainly composed of five monosaccharides, including mannose, galacturonic acid, glucose, galactose and arabinose. The similarity value of the 14 batches was above 0.9, indicating that similarity of fingerprints among different samples was high. The study can provide evidence for expanding the medicinal parts of D. officinale.

OBJECTIVETo measure and assess the quality of life (QOL) and to explore the influencing factors on patients with malignant lymphoma.

METHODSQOL of 110 patients with malignant lymphoma were marked using EORTC QLQ-C30 short form, and multiple linear regression models were used to study the main factors influencing the QOL of patients with malignant lymphoma on five functional scales (physical, role, cognitive, emotional, and social) and the total scores.

RESULTSThe influencing factors of quality of life on patients with malignant lymphoma appeared to be: history of relapse, refraining from smoking, older age, educational level, space for living, exercises, medical care system, and available health care programs. Relapse (beta = 5.997, P= 0.020) and refraining from smoking (beta = -6.526, P= 0.006) were associated with total QOL scores, educational level (beta = -2.144, P= 0.057), History of relapse (beta = 5.857, P = 0.003) was associated with total functional scales while exercises (beta= -0.771, P = 0.097) and refraining from smoking (beta= -4.106, P = 0.005) were with physical scales, refraining from smoking (beta = -4.644,P = 0.008) and older age (beta = 0.989, P= 0.029) were with role scales, relapse (beta = 14.035, P= 0.001) and older age (beta = 2.230, P= 0.023) were with cognitive scales, relapse (beta = 8.500, P= 0.031) and living space (beta = - 3.054, P= 0.0901) were with emotional scales and medical care system and available health care programs (beta = -6.577, P= 0.018) were with social scales respectively.

CONCLUSIONFactors as prevention of relapse, correct cognition on malignant lymphoma, reasonable exercise, refrain from bad habits, improving medical care system could all increase the functions of malignant lymphoma patient, and to improve their quality of life.

OBJECTIVETo investigate contrast-enhanced ultrasound imaging features of diabetic foot ulcers.

METHODSSixteen patients with diabetic foot ulcers underwent conventional and contrast-enhanced ultrasound examinations, and the features of contrast-enhanced ultrasound imaging were analyzed. Pathological examination was also carried out in some cases.

RESULTSContrast-enhanced ultrasound showed slow enhancement in the artery phase in the 16 ulcers after administration of SonoVue. The mean time of initial enhancement was 30.02 ± 2.35 s, and the mean time for the occurrence of peak enhancement was 37.54 ± 4.13 s. In 5 cases a homogeneous enhancement pattern was clearly displayed, and in the other 11 cases, a pattern of homogenous peripheral enhancement with non-enhanced patches within the ulcers was found. Contrast-enhanced ultrasound showed a greater ulcerous area than conventional ultrasound.

CONCLUSIONContrast-enhanced ultrasound is a valuable means for evaluating the ulcerous area and the treatment efficacy for diabetic foot ulcers.
