The effect of gelatin on anaero-cultivation of Bifidobacterium adolescent is and stabilization of its living cell in dried preparation was investigared. It was shown that the well-distributed mixture of gelatin and medium could have a cushioning effect on pH reduction resulting from acid-production while incubating, and the dried mixture comprising living cell of bifidobacterium adolescentis was prepared, in which the stability and viability of cell come from cultures of gelatin mixture was increased compared with that without gelatin mixture. It was shown that oxygen toxicity to anaerobic cell was well reduced because of cell immobilization by the gel mixure after drying with saccharide substance , and then fermentable dynamics in 50L fermentor was tested as well as the relationship of growth kinetics, pH, dissolved oxygen rate, and content of soluble solids.

Purpose:To investigate the association between the expression of vascular endothelial growth factor (VEGF) and p53, and their influence on clinicopathological characteristics and prognostic value in gastric cancer.Methods:A total of 108 paraffin embedded gastric cancer tissues were stained with the monoclonal antibodies VEGF and P53 protein by immunohistochemistry.Results:VEGF and P53 expression were observed in 53.7% and 57.4% of gastric tumors, respectively. A significant correlation was found between VEGF and p53 status ( P

Objective To evaluate the clinical effect of salmeterol xinafoate and fluticasone propionate powder for inhalation combined ipratropium bromide aerosol in patients with stable chronic obstructive pulmonary disease (COPD).Methods One hundred and twenty patients with stable COPD was randomly divided into control group and observation group with 60 patients each.The control group was received ipratropium bromide aerosol inhalation,and the observation group was given salmeterol xinafoate and fluticasone propionate powder for inhalation and ipratropium bromide aerosol for 6 months.BODE index,SGRQ scores,plasma cortisol and bone mineral density were compared between two groups before and after treatment.Results BODE index scores had no significant difference between two groups before treatment (P＞0.05).After treatment,BODE index scores,dyspnea scale,FEV1％,6MWD and BODE index total scores in observation group were superior to those in control group [ (1.9 ± 0.5) grades vs. (2.3 ± 0.5)grades,(58.5 ± 7.3)％ vs.(50.4 ± 6.2)％,(411.1 ± 56.8) m vs.(347.5 ± 60.4) m,(3.3 ± 1.0) scores vs.(3.8 ± 1.3 ) scores ],there were significant differences (P＜0.05 ).SGRQ scores had no significant difference between two groups before treatment (P＞0.05 ).After treatment and in SGRQ scores,respiration symptom,limitation of activity,disease influence scores in observation group were significantly lower than those in control group [ (20.7 ± 10.3 ) scores vs.(37.9 ± 14.4) scores,(20.7 ± 9.5 ) scores vs.(34.8 ± 13.0) scores,(16.3 ± 6.7) scores vs.(27.2 ± 11.8) scores,(17.5 ± 7.0) scores vs. (34.6 ± 12.3) scores],there were signiticant differences (P＜0.01 ).There were no significant difference of plasma cortisol and bone mineral density between two groups (P＞0.05).Conclusions Salmeterol xinafoate and fluticasone propionate powder for inhalation and ipratropium bromide aerosol in patients with stable COPD can greatly improve the lung function and life quality and with less adverse reaction.

Objective To observe the effect of acupuncture penetrated from Tiaokou (ST38) to Chenshan (BL57) combined with exer-cise on affected limbs of shoulder-hand syndrome (SHS) at stage I after stroke. Methods 40 inpatients with SHS at stage I after stroke from January, 2013 to December, 2014 were randomly divided into treatment group (n=20) and control group (n=20). The treatment group accept-ed acupuncture from Tiaokou to Chenshan on unaffected sides and exercise of affected upper limbs, and the control group accetpted routine acupuncture on Triple Shoulder Acupoints on affected sides. They were assessed with Pain Rating Index (PRI), Fugl-Meyer Assessment (FMA) and modified Barthel Index (MBI) before and 4 weeks after intervention. Results The incidence of improvement was 90% in the treatment group, and 80%in the control group (χ2=0.784, P=0.376). The scores of PRI decreased (t>5.37, P<0.001), and the score of FMA and MBI increased (t>4.66, P<0.001) significantly after intervention. The score of FMA and MBI improved more in the treatment group than in the control group (t>2.25, P<0.05). Conclusion Acupuncture from Tiaokou to Chenshan combined with exercise is more effective on SHS at stage I after stroke than conventional Triple Shoulder Acupoints.

Objective To investigate the application of PBL teaching mode in laboratory diagnosis teaching. Methods 80 clinical medicine undergraduate students were divided into two groups. Tradition lecture was conducted to control group in laboratory diagnosis teaching,while PBL teaching mode PBL teaching mode was carried out to experiment group,and then the mastery of knowledge and appreciation on these two teaching modes was compared. Results The students in the experiment group mastered knowledge better than those in the control group,and the gratification of appreciation on PBL teaching mode was higher than that on the control group. Conclusion The activeness,energeticity,ability of self-study and combination diathesis of the students were improved through PBL teaching. There was good mutual communication between teacher and students and the teaching quality was improved.

Objective To investigate the suitable mode of cognitive-behavioral therapy for lung transplant recipients during waiting for lung and evaluate the effect to improve patients' physical and mental state.Methods 50 cases were randomly divided into the experimental group and the control group,each group with 25 cases.The control group received conventional treatment.The experimental group received cognitive-behavioral therapy in addition to conventional treatment.SAS and vital signs were measured in the two groups on admission,2 weeks and 4 weeks after admission.Results The SAS score of the experimental group was lower than the control group 2 weeks and 4 weeks after admission and SAS score decreased as the intervention extended.The SBp of the experimental group was lower than the control group 4 weeks after admission.There was no significant difference of DBp between two groups.The heart rate of the experimental group was lower than the control group 4 weeks after admission.The heart rate of the experimental group was lower on 2 weeks and 4 weeks after admission than on admission.4weeks after admission,the respiratory rate of the experimental group was lower than the control group and on admission.Conclusions Cognitive-behavioral therapy can reduce the level of anxiety and keep vital signs stable with good feasibility and effectiveness.

Objective To observe the effects of treadmill training on hindlimb motor recovery and noradrenaline (NA) fibers in rats with spinal cord contusion.MethodsSpinal cord contusions at the T10 level were induced in 3-month old female SD rats by dropping a 10 g rod from a height of 25 mm.The injured rats were then randomly divided into a control group and a treadmill training group ( n =15 in each group).Treadmill training began 1 week post-injury.No treatment was administered to the control group rats.Hindlimb motor function was evaluated weekly from the 1 st to the 9th week post-injury using Basso Beattie Bresnahan (BBB) scores and average combined scores (ACOs).The expression of dopamine beta hydroxylase (DBH) in the spinal cord caudal to the injured area was detected by immunohistochemical staining.ResultsThe treadmill training group exhibited significantly greater improvement in BBB scores from the 3rd week to the 7th week and in ACOs from the 2nd to the 9th week post-injury compared with the control group.The number of DBH positive fibers in the injured spinal cords and the number of DBH positive neurons in the injured frontal horns were also significantly higher in the training group.ConclusionsTreadmill training can promote the recovery of hindlimb motor function in rats after spinal cord contusion,perhaps by increasing the number of DBH positive fibers and DBH positive neurons.
