Objective To explore the effect of psychological intervention on knee osteoarthritis patients. Methods A total of 92 OA patients were included into a one-month randomized controlled followup study, 47 of them were treated with combined psychological intervention, the other 45 cases were routinely treated. All cases were investigated on their demographic information , physiological parameters and score of the short form-36 health survey questionnaires (SF-36), self-rating depression scale (SDS) and self-rating anxiety scale (SAS). Statistics method used t-test and variance analysis. Results There was no signi-ficant difference in terms of the physiologic parameters changes between before and after treatment (P＞0.05) of the two groups. ① The SDS scores of the two groups decreased gradually after the treatment (P＜0.05),while there was remarkable descending of SDS score in patients of psychological intervention group (P＜0.05). ② The SAS scores of the two groups decreased gradually after the treatment (P＜0.05). And there was no significant difference between the two groups (P＞0.05). Compared with the non-intervention group, the fourfactors scores including physical function, pain, vitality and role limitations due to emotional problems of the intervention group were significantly improved (P＜0.05). Anegative correlation was observed between SDS and PF, BP, GH, VT and SF (r=-0.739-0521,P＜0.05). SAS was correlated negatively with VT and SF (r=-0.699～-0.475,P＜0.05). Conclusion Psychological intervention could ameliorate the depression of knee osteoarthritis patients. The quality of life of knee osteoarthritis patients can be improved by psychological intervention.

To investigate the role of NADH in preventing apoptotic damage of human hepatic cells induced by chemotherapy drug cisplatin, the ultrastructural changes in hepatic cells were examined with transmission and scanning electron microscopy, propidium iodide (PI) staining was used to measure the apoptotic rate with flow cytometry, the expressions of p53 and bcl 2 gene were detected with RT PCR, the change in caspase 3 and caspase 8 of apoptotic molecules was examined with colorimetric assay. The results showed that, compared with the group of cisplatin, morphological apoptotic changes were not obvious, the apoptosis rate was significantly decreased, p53 mRNA expression was decreased, bcl 2 mRNA expression was increased, caspase 3 and caspase 8 activity levels were kept in a low level in the group of NADH /DDP. The study indicates that NADH can prevent apoptosis of human hepatic cells, and increase the possibility of using NADH to reduce side effects of chemotherapy.

OBJECTIVE:To observe the influence of capecitabine combined with radiotherapy on postoperative survival rate, relapse rate and survival quality of elderly patients with rectal cancer at Ⅱ-Ⅲ stage. METHODS:110 patients with rectal cancer atⅡ-Ⅲ stage were selected and randomly divided into control group and observation group with 55 cases in each group. Both group received radical resection of rectal carcinoma. Control group was given three dimensional conformal radiation therapy(3DCRT)af-ter operation;observation group was additionally given capecitabine 1 500 mg/m2,d1-14,qd,on the basis of control group. A treatment course lasted for 21 d,and both groups received 2 courses of treatment and followed up for 3 years. The survival rate and metastasis and recurrence rate of 2 groups were compared as well as KPS score before and after treatment. Toxic reaction of 2 groups was also observed. RESULTS:The follow-up total survival rate and disease-free survival rate of observation group were 89.09%and 76.36%,which were significantly higher than 74.55%and 54.55%of control group;the distant metastasis rate and lo-cal recurrence rate were 12.73% and 5.45%,which were significantly lower than 30.91% and 21.82%,with statistical significance (P<0.05). KPS score of 2 groups were increased significantly,between 2 groups before and after treatment ,with statistical signifi-cance(P<0.05);Comparison between groups(P>0.05). There was no statistical significance in the incidence of nausea and vom-iting,diarrhea and urinary tract reaction between 2 groups (P>0.05);but the incidence of bone marrow arrest in observation group was significantly higher than control group(P<0.05). CONCLUSIONS:Capecitabine combined with 3DCRT can effectively improve postoperative distant survival rate of patients with rectal cancer at Ⅱ-Ⅲ stage,and reduce the metastasis and recurrence risk;do not lower life quality and induce serious adverse reactions.

Objective To evaluate the effect of intrathecal resveratrol on activation of Ca2+/ calmodulin-dependent protein kinase Ⅱ (CaMK Ⅱ) in spinal dorsal horn neurons of rats with bone cancer pain.Methods Thirty-two adult female Sprague-Dawley rats,weighing 180-220 g,were equally randomized into 4 groups using a random number table:sham operation group (group S),bone cancer pain group (B group),and bone cancer pain + solvent control group (BD group).Walker 256 mammary gland cancer cell suspension (4× 105 cells/ml) 5 μl was injected into the medullary cavity of the right tibia in B,BR and BD groups.Normal saline 5 μl was given in group S.On 12,13 and 14 days after injection of mammary gland cancer cells,resveratrol 200 μg/10 μl was injected intrathecally once a day in group BR,and 1％ dimethyl sulfoxide 10 μl was intrathecally injected once a day in group BD.Before injection of mammary gland cancer cells (T0) and on 3,5,7,10,12 and 14 days after injection of mammary gland cancer cells (T1-6),mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured.The rats were then sacrificed and L4,5 segments of the spinal cord were removed for confirmation of the location of phosphorylated CaMK Ⅱ (p-CaMK Ⅱ) in spinal dorsal horn neurons (by immunofluorescence) and for detection of p-CaMK lⅡ expression (using Western blot).Results Compared with group S,MWT and TWL were significantly decreased at T2-6,and p-CaMK Ⅱ expression was upregulated at T6,and p-CaMK Ⅱ was mainly co-expressed with neurons in B,BR and BD groups.Compared with group B,MWT and TWL were significantly increased at T5,6,and p-CaMK Ⅱ expression was down-regulated at T6 in group BR.There was no significant difference in MWT,TWL,and p-CaMK Ⅱ expression at each time point between group B and group BD.Conclusion Resveratrol can alleviate hyperalgesia in rats with bone cancer pain and inhibited activation of CaMK Ⅱ in spinal dorsal horn neurons may be involved in the mechanism.

Objective To investigate the changes in pentane (marker of lipid pemxidation) concentuation in the expired air induced by hepatic ischemia-reperfusion(IR)injury in rabbits.Methods Thirty healthy male Japanese white rabbits weighing 2.4-3.0 kg Were randomly divided into 2 groups(n=15 each):group Ⅰ sham operation and group Ⅱ hepatic IR.Anesthesia was induced with 3% pentobarbital 30mg/kg iv and maintained with The animals were tracheostomized and mechanically ventilated.Femoral artery and vein were cannulated for BP monitoring and blood sampling.Hepatic blood flow was occluded for 25 min followed by 180 min reperfusion.The expired air was collected before(baseline,T0)and at 1,10 and 25 min of ischemia and at 1,10,25,60,120 and 180 rain of reperfusion (T1-9) for determination of pentane concentration which was extracted by solid phase micro-extraction (SPME) and detected by gas chromatography-mass spectrography(GC-MS).Blood samples were also taken at the above time points for measurement of serm ALT,AST and SOD activities and MDA concentration.The animals were killed at the end of 180 min reperfusion.Liver specimens were obtained for histology.Results There was no significant difference in age,body weight,MAP and HR between the two groups.There was no significant change in pentane concentration in the expired air and the ALT,AST and SOD activities and MDA concentration at all time points as compared with the baseline in sham operation group.In IR group the pentane concentration in the expired air was significantly increased at T4,5 and the ALT and AST activities and MDA concentration were significantly increased and SOD activity was significantly decreased at T7-9 as compared with the basehne and the sham operation group.Conclusion The pentane concentration in the expired air can reflect the occurrence of lipid peroxidation during hepatic IR injury.
