Objective To explore the effect of aerobic exercise and progressive relaxation training on cancer-related fatigue in lung cancer patients during chemotherapy. Methods Sixty lung cancer patients undergoing chemotherapy were randomly assigned to an experiment group (n=30) and control group (n=30). The patients in the study group received regular nursing plus 6 weeks aerobic exercise intervention and progressive relaxation training, while the patients in the control group only received regular nursing care. The effect of intervention was evaluated by the Piper fatigue scale (PFS). Results Before the intervention, three were no difference in the PFS scores and all dimentions scores between the two group. After the intervention, the total score of the cancer-related fatigue and the score on every dimension of PFS were significantly lower than those of the control group (P<0.01). For the control group, the total score and the score on the dimension had insignificant difference between pre-and post-intervention (P<0.01), except the dimensions of emotion and feeling which showed significant differences between pre- and post-intervention (P < 0.05). Conclusion Aerobic exercise and progressive relaxation training can decrease the cancer-related fatigue and improve the quality of life.

OBJECTIVE:To optimize the processing technology of nine steaming nine drying of Rehmannia glutinosa. METH-ODS:L9(34) orthogonal experimental design was adopted to investigate the effects of the amount of added wine,steaming time and drying way on processing technology using the content and property of 5-hydroxymethyl furfural,acteoside,reducing sugar wa-ter extract,and character score as indexes. Comprehensive balance method was used for result evaluation,and optimized technolo-gy was validated. RESULTS:The optimized processing condition was as follows as the amount of added yellow wine 40%,steam-ing for 9 times,lasting for 6 h each time,blast drying at 70 ℃. Average value of each factor in validation test was 4.030 mg/g, 0.117 mg/g,0.376 7 g/g,0.733 g/g and 9.0 points,respectively. Their RSDs were 1.78%,2.9%,1.54%,2.13% and 0.1%(n=3). CONCLUSIONS:Optimized technology is reasonable and controllable in product quality,and can provide reference for quality control study of nine steaming nine drying of R. glutinosa.

Conotruncal defects(CTD) is a kind of severe cardiovascular abnormality, which is the major cause of death in rinatal pelriod. Some researches suggest that CTD and 22q11 microdeletion had close relationship. In addition, HIRA gene is located in 22q11, which was speculated as a candidate gene in CTD.

Objective To investigate the effect of atorvastatin on circulating endothelial progenitor cells (EPCs) and BP in hypertensive patients with normal lipid profiles.Methods Thirty-eight hypertensive patients were randomly to receive conventional anti-hypertensive drugs (n=18) or conventional anti-hypertensive drugs plus atorvastatin(20 mg QN)combination treatment (n=20).Eight healthy subjects were given atorvastatin (20 mg QN) for 8 weeks as control group.Before and after treatment,peripheral blood were drawn to isolate and culture EPCs.The circulating EPCs were identified by direct fluorescent staining under a laser scanning confocal micro- scope.EPCs populations were assessed using the colony forming unit assay (EPC-CFU) through a inverted phase contrast microscope 10 days after culture.Results After treatment,SBP was decreased (conventional treatment from 165.8?10.3 to 132.7?10.3 mmHg;combined group from 163.7?10.2 to 127.9?10.1 mmHg P

To investigate vincristine-induced dopaminergic neurons toxicity and mechanism, and explore the molecular target to reduce the toxicity, zebrafish was chosen as a model animal, based on RT-PCR, Western blotting, whole mount in situ immunofluorescence and other technical means. The results showed that the transcription levels of tyrosine hydroxylase gene and dopamine transporter protein gene were inhibited. Furthermore, the number of dopaminergic neurons was decreased by vincristine. Autophagy was suppressed and beclin1 gene expression was inhibited in a dose-dependent manner by vincristine in larval zebrafish. Up-regulated beclin1 partly reduced vincristine-induced neurotoxicity, and down-regulated beclin1 increased toxicity. Beclin1 plays an important role in vincristine-induced dopaminergic neurons toxicity.

The Notch pathway is an evolutionarily conserved signal transduction pathway. It consists of a complex system of interaction. Its function is associated with the embryonic development and cell differentiation regulation. Studies in recent years have demonstrated that Notch pathway is associated with specific human diseases, in which Notch3 signaling pathway is closely associated with the nervous system development and the structural integrity of blood vessels. Notch3 mutation may cause cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy.

Objective To investigate the protective effect of exercise on osteopenia female rats caused by ovariectomy and its mechanism. Methods Twenty-four female rats aged 6 months were randomly divided into 3 groups: control group(CON),ovariectomized model group(OVX) and exercise group(Ex).The ovariectomy operation was performed with rats in OVX and Ex groups. Rats in Ex group were trained on a treadmill at a velocity of 18m/min for 1h, once daily for 5 days a week. Each group of rats were sacrificed at 12 weeks postoperatively and Dual-energy X-ray absorptiometry was carried out to measure the bone mineral density(BMD) of the femur. IGF-1 proteins in trabecular bone of proximal femur were examined by using immunochemical stain and the intensity of IGF-1 was determined by use of imaging analysis techniques. The apoptotic osteocytes in the trabecular bone of proximal femur were detected by using terminal-deoxynucleotidyl mediated nick end labeling (TUNEL) technique. Results The BMD of CON, Ex and OVX group was (0.170?0.011)g/cm2,(0.154?0.013)g/cm2 and(0.167?0.013)g/cm2, respectively. The difference of the BMD level between Ex and CON groups was not significant, however, the BMD level in OVX group was significantly lower than that of the Ex and CON groups (P

Objective: To obtain a strain which has stronger antagonistic effect against Streptococcus mutans(S. mutans), and then to study the antagonistic effect of the fermentation filtrate of the strains.
