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.

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

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 analyze the pattern of early catch-up growth In children with prepubertal short stature and various secretory forms of growth hormone(GH)following recombinant human growth hormone (rhGH)treatment and to explore the mechanism. Methods Sixty-two children with prepubertal short stature and various GH secretory forms were analyzed retrospectively, 27 with complete growth hormone deficiency (cGHD), 23 with partial growth hormone deficiency (pGHD)and 12 with idiopathic short stature(ISS). According to the GH peak value in GH provocative test, the group of pGHD was divided into pGHD-1(5.0-6.9μg/L)and pGHD-2(7.0-9.9μg/L). Height velocity, increase in height standard differentiation score (SDS), was calculated; serum levels of somatotrophic axis hormone were detected and bone age was determined. Results The quick early catch-up growth in different groups were similar in the initial 6 months. While that in the ISS group persisted for shorter period and was correlated with lower level in serum GH-binding protein(r=0.526,P=0.025)and Δinsulin-like growth factor-binding protein-3 (IGFBP-3) SDS (r=0.532,P=0.034) after rhGH treatment. The same doses of rhGH were applied to children with cGHD and pGHD. Children with pGHD-1 showed similar response to rhGH,regarding height velocity and ΔIGFBP-3 SDS, as compared with those of cGHD. However, children with pGHD-2 presented similar response with ISS, being worse than cGHD. Conclusion Downregulation of GH receptor and decrease in post-receptor effect seem to be the mechanism leading to early retardation in ISS. The incomplete catch-up growth in pGHD-2 may be caused by relatively inadequate rhGH dose. The cut-off value of GH provocative test in diagnosing GHD is more reasonable to be 7μg/L.

Objective To understand how serum DHEAS levels change with sex,age and stage of sexual maturation in children and adolescents and explore the relationship between adrenarche and pubertal maturatiotL Methods Serum samples from 120 healthy boys,198 healthy girls and 152 girls with idiopathic central precocious puberty (ICPP) were examined for DHEAS.Referenee ranges for healthy children and adolescents and statistical difierences between heahhy girls and ICPP girls were analyzed with respect to sex,age and stage of sexual maturation.Results Both healthy children and ICPP girls showed extremely low levels of serum DHEAS and they were not related to sex.age or tanner stages in the individuals below age of 6 years.Serum DHEAS levels were positively related to both age (above age of 6 years)and tanner stage in healthy groups(r=0.69 and 0.71 respectively,P＜0.01).After the onset of puberty,serum DHEAS levels appeared to be higher in boys than that in girls within the same tanner stage(P＜0.05).Within the individusis in the same age group with same sex.serum DHEAS levels increased along with pubertal development.While within the individuals in same tanner stage group with salne sex after puberty onset.serum DHEAS levels showed no significant difference among different age groups.For example.there was no difference in serum DHEAS levels of healthy girls in tanner stage Ⅲ among different age subgroups(age of8-9;age of 10-11,age of 12-13)and the mean vallie of serum DHEAS was 532.0-557.8μg/L(F=0.21,P=0.98).In different age subgroups above age of 6 years,Z scores for serum DHEAS in ICPP girls were highher than them healthy ones with advanced tanner stages(0.97us-0.1 and 1.39us-0.08,JP≤0.01)In different tanner stage subgroups.Z scores for serum DHEAS showed no difierence between healthy and ICPP girls despite apparent different age ranges(0.00 us-0.31-0.18,P＞0.05).Conclusions Serum DHEAS level increased along with both age (above 6 years) and tanner stage in healthy children and adolescents.There was no gender difference until the onset of puberty.It was demonstrated that adrenache and gonadarche were related to each other.Reference ranges for adolescents should be interpreted according to sex.age and tanner stage simultaneously.
