There are increasing experimental evidences and clinical data showing that inflammatory reaction plays an important role in the production and development of atherosclerosis. Inflammatory process promotes the production and release of inflammatory factors by activation of monocytes and stimulation of endothelial cells, which stimulate the migration and proliferation of vascular smooth muscle cells. Hydrolases and cytokines are released from the activated and stimulated cells to increase local lesion and form atherosclerotic plaque with the development of inflammation. So, on the basis of the new pathogenesis of atherosclerosis,scientists try to interfere with atherosclerosis by anti-inflammatory pathway. This paper reviews the progress of drugs against atherosclerosis by the modulation of C reaction protein ,CD40-CD40L,infection and NF-?B.

AIM To observe the protective effect of quercetin on vascular endothelial cells injured by homocysteine in rabbits. METHODS The model of the vascular endothelial cells of rabbits injured by homocysteine was established; 50 mg?kg -1, 100 mg?kg -1 and 200 mg?kg -1 of quercetin were orally adminstered. After 30 days, the number of CEC, levels of MDA and NO,SOD activity in the serum were determined; ET concentration in the plasma was detected. The thoracic aorta was isolated to observe the vascular reactivity to nitroglycerin and ACh and tissue change. RESULTS The number of CEC, levels of MDA and ET were decreased and levels of SOD and NO were significantly increased in the quercetin-administered group compared with the injured group.Non-endothelium dependent relaxation of vessel caused by nitroglycerin was similar in all groups. Endothelium dependent relaxation caused by ACh was reduced in the injured group,whileas the relaxation trended to the normal degree in the quercetin-administered group. Pathological examination showed that quercetin was effective on the injured endothelial cells. CONCLUSION Quercetin produces protective effect on the injured vascular endothelial cells by homocysteine in rabbits.

AIM: There are many active components of tonifying kidney to strengthen the bone in Kanggu Zengsheng capsule, but there are few reports about its effect in treating bone fracture. CR molybdenum target X-ray is often used in mammary gland examination and disease diagnosis. This study detected the callus density during fracture healing in rats by CR molybdenum target X-ray to explore the promoting effects of Kanggu Zengsheng capsule on fracture healing. METHODS: The experiment was performed at the Laboratory Centre of Second Hospital of Hebei Medical University from July 2005 to March 2006. Sixty Wistar rats with an equal amount of males and females, 170-200 g, aged 9-10 months were randomly divided into experimental group and control group (n =30). After the tibial fracture model was made, the rats in the experimental group were given 1 mL Kanggu Zengsheng capsule suspension, 14.00-15.75 mg for each, once daily, while the rats in the control group orally took matching normal saline (9 g/L) once daily. All animals were executed under anesthesia by batch on the 3rd, 10th, 17th, 24th, and 33rd days after the operation, separately. The diameter of callus was measured with vernier caliper. The values of callus density were calculated by image analysis system in the CR molybdenum target X-ray. RESULTS: Sixty rats were all included in the final analysis. The photo of CR molybdenum target X-ray showed clear bone lines, and bone and soft tissue were evident. During the process of fracture union, there were significant differences in callus density between the two groups (P

Objective To investigate the expression of succinate dehydrogenase subunit A(SDHA)and subunit B (SDHB) in patients with renal cell carcinoma (RCC),and its relationship with the clinicopathologic characteristics. Methods The expression of SDHA and SDHB was detected in 179 cases of RCC by immunohisto-chemistry and the relationship between the SDHA ,SDHB expression and the clinicopathologic characteristics of RCC were analyzed. Results In 179 cases of RCC,18 cases(10.1%)were shown with negative or suspicious-negative expression of SDHA and SDHB,including 2 cases(1.1%)with suspicious-negative expression of SDHA and SDHB. 12 cases(66.7%)had tumor located in left kidney and 6 cases(33.3%)had tumor located in right kidney. The well-differentiation group contained 15 cases(83.3%),moderate-differentiation group contained 1 case (5.6%)and poor-differentiation group contained 2 cases(11.1%). Most of SDH negative and suspicious negative RCC had the following characteristics that the normal renal tubule could be seen within the tumor. The tumor was composed of polygonal cells arranged in nest ,and the polygonal cells were separated by a fine fibrovascular stroma. The nuclei were shown around with vesicular chromatin. The eosinophilic flocculet material ,vacuole and eosino-philic inclusion body could be seen in the cytoplasm of tumor cells. Conclusion The RCC cases with negative expression of SDHA and SDHB protein have unique histological features ,with significantly higher incidence in the left kidney than that in the right kidney.

[ ABSTRACT] AIM: To evaluate the guiding effect of high-frequency stimulation ( HFS) on renal denervation ( RDN) , and to compare the similarities and differences of blood pressure changes at the time of electrical stimulation and radiofrequency ablation .METHODS:A total of 6 Kunming dogs were included in this study .Renal artery abnormalities were excluded by angiography .High-frequency stimulation and radiofrequency ablation were performed at the same sites from distal to proximal segments of the renal artery .Invasive blood pressure ( BP) was recorded during the whole proce-dure.The change of the blood pressure was analyzed .HE and Masson staining was adopted to detect the structural changes in the wall of the renal artery and surrounding tissues .The immumohistochemical staining for tyrosine hydroxylase ( TH) was used to observe the renal nerve damage after ablation .RESULTS: Electrical stimulation and radiofrequency ablation were delivered in a total of 50 sites.The BP increasing response was induced at 34%sites (n=17), while the rest sites (66%, n=33) had no response.Compared with the baseline , HFS caused the increases in systolic BP of (0.34 ±3.38), (0.41 ±3.04), (10.47 ±5.73), (13.27 ±3.63), (10.17 ±1.87) and (0.78 ±1.87) mmHg in 6 serial 20 s time segments during 120 s of HFS at positive BP response sites .Similarly, the increases in systolic BP by (-0.88 ±3.44) , (-1.64 ±3.47), (13.17 ±3.12), (12.82 ±3.21), (9.50 ±2.68) and ( -6.09 ±2.21) mmHg were observed dur-ing 120 s of ablation procedure at the same sites in 6 serial 20 s time segments .At non-responding sites , HFS and ablation failed to cause a significant increase in systolic BP .The mean area of nerves in the response sites was ( 0.51 ±0.28 ) mm2, whereas that in non-response sites was (0.09 ±0.06) mm2(P<0.01).The average absorbance values of TH in re-nal nerves at ablation and non-ablation sites were 0.031 ±0.015 and 0.085 ±0.018 ( P <0.01 ) , respectively . CONCLUSION:Renal sympathetic nerves can be effectively mapped by HFS .Radiofrequency ablation guided by HFS is valid to injure sympathetic nerves around renal artery .

Objective To evaluate the effect of a nurse-led case management intervention on arm function and uncertainty for women with breast cancer.Methods 90 women with breast cancer were divided into the intervention group and the control group according to their nurses,with 45 patients in each group.All participants were followed six months after surgery.The intervention group attended a 6-month nurse-led case management program,while the control group received the routine care and follow-up only.Questionnaires on arm function and uncertainty were administered 1 month,3 months and 6months after the surgery respectively.Score changes were compared by repeated-measure ANOVA and MANOVA.Results The arm function of the intervention group was better than the control group,except for the 10th day after the operation,there were significant differences at other three time points.The disease uncertainty level of the intervention group was better than that of the control group,except for the dimension of unpredictability,there were evident differences in other dimensions at other three time points.Conclusions The nurse-led case management intervention could improve arm function recovery and decrease the uncertainty to disease of breast cancer survivors.

Objective To investigate the outcomes of increased gestational diabetes mellitus (GDM) and the influencing factors after the implementation of the new GDM diagnostic criteria.Methods A total of 1 439 GDM women who delivered in the Peking University First Hospital between May 1,2011 and December 31,2012 were studied and divided into two groups.Group Ⅰ included the women who met the new GDM diagnostic criteria (fasting plasma glucose and 1 or 2 h plasma glucose levels for 75-g oral glucose tolerance test performed between 24 and 28 weeks of gestation were no less than 5.1,10.0 and 8.5 mmol/L),but did not meet the National Diabetes Data Group (NDDG) criteria;and Group Ⅱ included the women who met the NDDG criteria only.Women in Group Ⅰ were further divided into two subgroups according to whether attending the one-day GDM outpatient visit.Follow-up rate and detecting rate of abnormal glucose metabolism at 6-12 weeks after delivery were analyzed.Chi-square test,t test and multivariate Logistic analysis were used for statistical analysis.Results There were 849 GDM women in Group Ⅰ (59.0％,849/1 439) and 590 (41.0％,590/1 439) in Group Ⅱ.The follow-up rate in group Ⅰ was lower than in group Ⅱ [25.9％(220/849) vs 32.0％(189/590),x2=6.112,P=0.013].There were five cases of impaired fasting glucose and 34 impaired glucose tolerance in Group Ⅰ;and four cases of impaired fasting glucose,56 impaired glucose tolerance,eight impaired fasting glucose tolerance with impaired glucose tolerance and five diabetes mellitus in Group Ⅱ;there were significant differences [17.7％(39/220) vs 38.6％(73/189),x2=33.810,P=0.000].(2) In Group Ⅰ,the increased glucose level at 2 h in oral glucose tolerance test during pregnancy (OR=1.547,95％CI:1.038-2.306,P=0.032) and family history of diabetes mellitus (OR=1.879,95％CI:1.066-3.313,P=0.020) were risk factors for postpartum abnormal glucose metabolism,while breast-feeding was a protective factor (OR=0.290,95％CI:0.092-0.914,P=0.035).(3) In group Ⅰ,the follow-up rate in those who attended the one-day GDM outpatient visit was higher than those who did not [30.7％(185/603) vs 14.2％(35/246),x2=23.780,P=0.000],but the detecting rate of postpartum abnormal glucose metabolism were similar in women attending the one-day GDM outpatient visit and those not attending [17.8％(33/185) vs 17.1％(6/35),x2=0.020,P=0.887].Conclusions Increased GDM women still have glucose metabolism abnormality after delivery,especially those who have higher glucose level at 2 h after glucose intake in 75 g oral glucose tolerance test during pregnancy and who have a family history of diabetes mellitus.The one day GDM outpatient visit may improve the follow-up rate for these women.

OBJECTIVE:To evaluate therapeutic efficacy of strontium dichloride (89SrCl2 ) combined with local radiotherapy for pain caused by malignant tumor bone metastasis. METHODS:115 patients with malignant tumor complicated with bone metasta-sis were analyzed retrospectively,and they received therapy regimen of 89SrCl2 combined with local radiotherapy. The amount of 89SrCl2 was calculated according to body weight of patients,and given by intravenous injection manner at the beginning of treat-ment,and then radiotherapy target section was confirmed according to iconography for irradiation. Effect of bone pain control,side effects (myelosuppression) and the effect of treatment on quality of life were evaluated at the end of treatment. RESULTS:After one month of treatment,there were 32 cases of complete remission(CR)and 62 cases of partial remission(PR),and total effec-tive rate was 81.7%;after one month of treatment,6 cases(5.1%)suffered from Ⅲ-Ⅳ degree myelosuppression;but there was none of Ⅲ-Ⅳdegree myelosuppression case after 2 months of treatment. The improvement of overall quality of life was not signifi-cant after treatment. Pain symptoms,general situation and sleep quality all improved significantly. CONCLUSIONS:89SrCl2 com-bined with local radiotherapy can control pain caused by malignant tumor bone metastasis and induce side effect,and improve quali-ty of life to certain extent.
