Objective To investigate the effects of liver X receptor agonist on the expressions of C-reactive protein and CD40 ligand and smooth muscle cell ?-actin in the aorta of ApoE gene knockout mice with earlier atherosclerosis. Methods Male ApoE gene knockout mice (8-week old) were divided randomly into control group and T0901317 treatment group (n=6 in each group). The mice in T0901317 group were administered intraperitoneally with T0901317 at the dose of 20 mg?kg-1?d-1 for 4 weeks. Mice in the control group were only given equivalent amount of dimethyl sulfoxide (DMSO). The expressions of C-reactive protein and CD40 ligand and smooth muscle cell ?-actin were detected by immunological histochemical method. Results The expressions of C-reactive protein and CD40 ligand in the atherosclerotic plaque in the aortic wall were significantly lower in T0901317 group as compared with those in the DMSO control group (P0.05). Conclusion Liver X receptor agonist may reduce the formation of atherosclerotic lesions by inhibiting the inflammation and the expressions of C-reactive protein and CD40 ligand in the aorta of ApoE gene knockout mice.

Background and purpose: Docetaxel plus prednisone chemotherapy can improve the patients' survival for castrate-resistant prostate cancer. Angiogenesis inhibitors can also inhibit the growth of tumor. The curative effect of combined treatment is still not clear. This study aimed to evaluate the efficacy of docetaxel plus prednisone combined with thalidomide in treating castrate-resistant prostate cancer (CRPC) patients with bone metastasis. Methods:A total number of 78 CRPC patients were selected in Fuzhou General Hospital from Dec. 2008 to Jun. 2015. Seventy-eight patients were divided into two groups: 40 patients in chemotherapy group (docetaxel plus prednisone) and 38 patients in combined treatment group (docetaxel plus prednisone combined with thalidomide). A total number of 78 subjects were evaluated by the effective rate, the remission rate of bone pain, the prostate specific antigen (PSA) progression-free surviv-al, the overall survival and adverse effect. Results: The response rate (65.79%) and the remission rate of bone pain (86.84%) in combined treatment group were both higher than those in chemotherapy group (40.00% and 60.00%, P<0.05). The PSA progression-free survival (4.13 months), progression-free survival (4.25 months) and the overall survival (18.06 months) in combined treatment group were all longer than those in chemotherapy group (3.54, 3.75 and 16.26 months). The PSA pro-gression-free survival was significantly longer in combined treatment group (P<0.05). There was no significant difference in the overall survival between two groups (P>0.05). The rates of adverse effects including peripheral neuritis and lethargy in combined treatment group (26.32% and 55.26%) were higher than those in chemotherapy group (5.00% and 17.50%, P<0.05). Conclusion: Thalidomide combined with docetaxel plus prednisone in CRPC patients with bone metastasis can prolong the PSA progression-free survival and overall survival. The adverse effects are mild. It may become a new choice of treatment for CRPC.

Objective To evaluate the efficacy of pregabalin on painful radiation-induced brachial plexus injury.Methods A total of forty-five patients with painful radiation-induced brachial plexus injury were assigned to treatment group with pregabalin 150-600 mg/d combined with conventional therapy, and to control group with conventional treatment for 12 weeks.The visual analogue scale (VAS) and neuropathic pain symptom inventory (NPSI) were evaluated.The response rate (proportion of subjects with at least a 30％ to 50％ reduction in visual analogue scale) was evaluated as the primary endpoint.Results The response rate of the pregabalin group(36.4％) was significantly higher than that of the control group (9.1％) (x2 =4.98, P ＜ 0.05).Although hospital anxiety and depression level, clinical global impression of change, and clinical global impression of change (CGIC) did not differ significantly between pregabalin group and control group (P ＞ 0.05), improvements in neuropathic pain symptom inventory (NPSI), patient global impression of change (PGIC) and the sleep interference score(t =-6.62,-5.65,-6.16, P ＜ 0.05)suggested some utility in the management of radiation-induced brachial plexus.Conclusions Pregabalin treatment combined with conventional treatment exerts efficacy on patients with painful radiation-induced brachial plexus and patients are well tolerated.

Objective To establish and evaluate 3 kinds of minimally-invasive valve implantation model in vivo.Methods A novel tissue engineered heart valve(TEHV) manufactured by branched polyethylene glycol cross-linked acellular porcine valve and a minimally-invasive valve implantation system according to the design of Corevalve revalving system were adopted.After anesthesia,18 adult male goats were randomly divided into 3 groups: the ulrasound-directed orthotropic group (group A,n =6),angiography-directed orthotropic group (group B,n =6) and direct-released heterotopic group (group C,n =6),and all received minimally-invasive valve implantation orthotropically or heterotopically.4 weeks later,the valvular function was evaluated by CTA and/or echocardiography.Results All 3 kinds of caprine model were successfully constructed.The operation success rate of each group was A: 66.7％,B: 50.0％ and C: 100.0％,respectively(multiple x2 analysis,group A and B P ＞0.05; group A and C,group B and C,P ＜0.05).The operation-time of each group was A: (79 ± 18) min,B:(61 ±23) min,C: (45 ± 15) min(one-way ANOVA,P ＜0.05).The survival rate at4 weeks was A: 100％,B: 100％ and C: 83.3％ (multiple x2 analysis,P ＞ 0.05).Echocardiography and CTA proved the short-term function of implanted TEHV was satisfactory.Conclusion All 3 kinds of caprine valve implantation model can be established without cardiopulmonary bypass and blood transfusion.The devices and equipments required in group A is relatively simple,but the procedure cost longer time for it is hard to determine the right position by ultrasound.The application of angiography made the positioning much easier in group B while the procedure had to be performed in specific operation room with angiographic apparatus.Group C did rely on neither special equipments nor complex operation,but the valve leaflets cannot work normally,so this model was only suitable for testing in vivo characteristics such as biocompatiblities.

Objective To evaluate the efficacy and safety of donepezil in the treatment of cognitive dysfunction caused by radiation-induced encephalopathy.Methods A total of fifty-five patients with radiation-induced cognitive impairment were divided into treatment group with extra donepezil 5-10 mg/d combined with conventional therapy and control group with conventional treatment for 16 weeks.The cognitive function was assessed according to Montreal cognitive assessment (MoCA) and mini-mental state examination (MMSE) before and 16 weeks after treatment.Results After 16 weeks of treatment,the patients in treatment group displayed significantly greater improvement in cognitive function.In treatment group,the scores of patients after donepezil therapy in MoCA and MMSE were obviously higher than the control group (t =5.40,3.88,P ＜ 0.01).The scores in the visual space and executive function,naming,attention,abstract thinking,delayed memories also had improved,which suggested the statistically significant difference(t=-3.55,-3.08,-3.21,-2.58,-3.65,P＜0.05).The scores of control group unchanged accordingly.Conclusions Donepezil combined with conventional treatment was signally effective in the therapy of cognitive dysfunction caused by radiation-induced encephalopathy.

OBJECTIVETo learn about the photosynthetic characteristics of Sarcandra glabra and provide the theoretic references for its better planting.

METHODThe photosynthetic parameters of twenty different provenances of Sarcandra glabra were determined by Li-6400 portable photosynthesis system, and the data was analyzed by Excel and SAS software.

RESULTThe results showed that the light saturation point of different Provenances of S. glabra were almost about 800 micromol x m(-2) x s(-1), while the light compensation point of them were from 14.70 micromol x m(-2) x s(-1) to 48.68 micromol x m(-2) x s(-1). The curve of net photosynthetic rate had two peaks on sunny day, the first one was in the morning and the other one was in the afternoon. The photosynthetic "noon- break" of S. glabra appeared between 11:00-13:00, when the net photosynthetic rate goes down sharply. Intercellular CO2 concentration (C(i)), CO2 concentration (CO2S) and transpiration rate (T(r)) all have effect on the diurnal change of net photosynthetic rate (P(n)) of S. glabra, and the average correlation coefficient between P(n) and the parameters above were orderly as -0.89 (P < 0.01), -0.75 (P < 0.05) and 0.69 (P < 0.05);

CONCLUSIONS. glabra was a plant with characteristics of shade-tolerance, and through the way of covering, sprinkling for decreasing the surrounding temperature would be effective to reduce its "noon-break" time and increas its efficiency of photosynthesis.
