Background and purpose:The quality of life and psychological status of the advanced cancer patients has been widely valued. This study aimed to analyze the psychological status of the advanced cancer patients and its influence factors.Methods:The patients who were hospitalized in the palliative care department of Fudan University Cancer Center from Sep. 2011 to Mar. 2013 were included in this study. Self-rating anxiety scale(SAS), self-rating depression scale (SDS), EORTC QLQ-C30, social support revalued scale and symptom checklist 90 (SCL-90) were recorded and analyzed.Results:Fifty-six patients were included in this study, 18 were depression and 24 were anxiety while 16 of them were depression together with anxiety. The patients were divided into 2 groups according to their psychological status. There’s no signiifcant difference between the age and the social support between the two groups, while the mental disorders group have lower scores on body function, role function, emotional function and social function. The mental disorders were positive correlated with the symptoms score while negative correlated with the quality of life.Conclusion:There’s a high ratio of mental disorders in advanced cancer patients, the symptom scores and quality of life are related to mental disorders. We should pay more attention to the patients who were suffered more from the illness or had lower QOL scores.

Objective To detect the micrometastasis status and necessity of dissection of lymph nodes of hepatodudenal ligament in advanced gastric antral cancer. Methods Eighty-six lymph node samples of hepatodudenal ligament which were negative in routine pathological examinations were collected from 45 gastric antral cancer patients with radical dissection.The expressions of CK20 mRNA were detected for the existence of micrometastasis by RT-PCR. Results Micrometastasis was found in 46 out of 86 lymph nodes(53.49%) and 23 out of 45 patients(51.11%),significantly different from the routine pathological examinations(both P

Antagonism, esterase isozyme ployacrylamide gel electrophoretic (EST-PAGE) and cluster analysis was used in the study of 14 strains of Ganoderma. The results showed that there were 18 bands of EST with different Rf. Cluster analysis at 50% similarity level showed that all strains could be clustered into five groups, the first included Xian zhi, Da xian 823, Nan han, Yuan zhi 6, Tian zhi, Han zhi; the second included Chi zhi 10, Chi zhi 12, Chi zhi, Ri ben hong zhi; the third included Zi zhi, Hei zhi; the fourth included Xue zhi; the fifth included Bai zhi. And this result was similar to the result of antagonism and morphological characters. Because of its stablity, the technique of EST can be used for identification of Gamoderma.

Abstract Long noncoding RNA (lncRNA) is closely related to the pathogenesis of cancer,representing a burgeoning field in tumor research in recent years. MAGI2-AS3, a tumor-associated lncRNA, exerts pivotal roles in epigenetics, transcription and post-transcriptional regulation. Studies have suggested that MAGI2-AS3 may be involved in multiple stages of tumor development, and has potential applications for tumor diagnosis, therapy and prognosis. This review summarizes the expression, regulatory mechanism and clinical application value of MAGI2-AS3 in common malignant tumrs, providing the reference for tumor prevention and treatment.

The changes of carotid intima media thickness (cIMT) in type 2 diabetic patients with vitamin D insufficiency and subclinical macrovascular disease after 12 months' intervention therapy with calcitriol were observed.86 patients with vitamin D insufficiency [25 (OH) D＜30 ng/ml] and subclinical macrovascular disease were randomized to group A (n =44,treated with 0.5 μg/day calcitriol) or group B (n =42,blank control) for 12 months.40 patients in each group completed the follow up.After 12 months of therapy with calcitriol (0.5 μg.qd.po.),levels of high sensitive-Creactive protein,sCD36,and cIMT were significantly decreased,while 25 (OH) D and ankle brachial index were significantly increased (P＜0.05) in group A,suggesting that calcitriol could improve cIMT in patients with vitamin D insufficiency and subclinical macrovascular disease.

Objective To study the effect on body mass index ( BMI ) caused by treatment with Gonadotropin-releasing hormone analogs ( GnRHa) in girls with central precocious puberty ( CPP) or early and fast puberty ( EFP ) . Methods The BMI in 318 girls ( 227 CPP and 91 EFP ) treated with GnRHa alone was analyzed. Among them 89 were followed up to their final adult height. Results Before GnRHa treatment was started, thegirlswithCPPandEFPhadameanBMIstandarddeviationscore(SDS)forchronologicalage(BMISDSCA)of0.39 ±0.84andforboneage(BMISDSBA)of-0.11±0.69. Attheendoftreatment,themeanBMISDSCAwas0.59±1.01 and BMISDSBA was 0. 24 ± 0. 89, both were significantly higher than those at initiation. The increment in BMISDSBA (0.38±0.50)wasgreaterthanthatinBMISDSCA(0.21±0.56). Moreover,theratioofoverweight(BMI>85%)was significantly elevated. BMISDSCA of 89 girls who were visited at their final adult height was 0. 17 ± 1. 15, which was similar with BMISDS at initiation and in normal population. Conclusion The mean BMISDSCA of CPP and EFP was significantly higher than the general population, while BMISDSBA was significantly lower. During GnRHa treatment, BMISDS tended to be elevated. But it was reversible, for the mean BMISDS was back to normal at final adult height.
