Objective To explore the effects oflosartan on brain natriuretic peptide(BNP)and C-reactive protein(CLRP)in diabetic cardiomyopathy patients. Methods Sixty diabetics were divided into diabetic control group(30 cases)and diabetic cardiomyopathy group(30 cases), and the levels of BNP and CRP in plasma were determined. Then, diabetic cardiomyopathy group were divided into conventional treatment group(15 cases)and losartan treatment group(15 cases)by random digits table to take corresponding treatment for 12 weeks. The changes of cardiac function, the levels of BNP and CRP in plasma were detected and compared. Results The levels of BNP and CRP in diabetic cardiomyopathy group [(331.27 ±65.64)ng/L,(26.10±10.13)mg/L]were significantly higher than those in diabetic control group[(76.09±39.14)ng/L,(7.03±2.71)mg/L](P＜0.01). After treatment 12 weeks, the levels of BNP and CRP were significantly lower, left ventricular ejection fraction was significantly higher and left ventricular end-diastolic diameter was significantly lower in losartan treatment group than those in conventional treatment group(P＜0.05).Conclusions The increasing levels of BNP and CRP can reflect clinical severity of diabetic cardiomyopathy.Losartan can decrease the levels of BNP and CRP, and improve heart function, and it has better effective on diabetic cardiomyopathy.

There lack scientific methods for evaluating the treatment of cancer pain with external therapies of traditional Chinese medicine (TCM). The level of clinical study in this field needs to be improved. The authors assert that when external therapies of TCM are applied to treat cancer pain, different types of cancer pain should be distinguished and treatment should be applied according to such a differentiation. Under this framework scientific evaluation can be conducted. The authors also assert that the findings of randomized, blinded and controlled trials should be given particular attention, and it is necessary to include titration of morphine into clinical trails of external therapies for the treatment of cancer pain, not only complying with the three-ladder principle for treating cancer pain suggested by the World Health Organization, but also not influencing the effect evaluation of external therapies of TCM on cancer pain. Patient diaries recording pain were revised as observation indexes. The primary indicator of efficacy was the pain intensity score and the secondary indicators were the equivalent of morphine and the remission rate of pain. The time to onset, remission duration and comparison of assessment of pain influence can mirror the characteristics of external therapies of TCM on cancer pain.

OBJECTIVE: To study the antineoplastic mechanism of Pingfei Mixture. METHODS: Thirty C57BL mice bearing Lewis pulmonary carcinoma were randomly divided into 3 groups: saline control group, Pingfei Mixture group and cisplatin group. Fifteen days later, tumor tissues and spleens were taken out and made into unicellular suspension. Argyrophil staining was taken to carcinoma cells and cultured T cells. KL-2 style cell image analysis system was used to analyze the rate between AgNORs and nuclear region (I.S). RESULTS: There were dense brownish-black granules in tumor cell nuclear of saline control group. The brownish-black granules of Pingfei Mixture group and cisplatin group were less than those of saline control group. The differences of T cell I.S in these three groups were significant. The I.S of Pingfei Mixture was higher than that of the other groups, and the I.S of the cisplatin group was the lowest. CONCLUSION: Pingfei Mixture can inhibit tumor cell proliferation, although the effect is inferior to cisplatin. Pingfei Mixture can also promote T cell proliferation and its effect was superior to cisplatin.

A medical studies have indicated that there would be a defense response from human body after TBI,which mainly comes with inflammatory reaction. Human body's resistance seems likely to be enhanced,during this process, by inflammatory cytokines leading to rehabilitation of the cellular organization.However,a strong Inflammation from the whole human body may be caused due to the excessive activation,which, instead, worsens secondary brain injury. This article discusses the relationship between cytokines and traumatic brain injury.

OBJECTIVE To investigate the protective effect of velvet antler polypeptides(VAP)on hydrogen peroxide( H2 O2 )-induced injury in vascular endothelial cells and the possible mechanism.METHODS The EVC-304 cells cultured invitrowere incubated with H2 O2 for another 12 h after pretreat-ment with VAP 20,40 and 80 mg·L-1 for 24 h. Cell viability was determined by MTT assay, Hoechst333258 staining was used to observe cell morphology,the activity of superoxide dismutase (SOD)and the level of malondialdehyde( MDA)were detected with kits and the expression of heat shock protein(HSP70)and caspase 3 was detected by Western blotting. RESULTS Compared with the normal control group,the cell survival rate was decreased significantly in H2 O2 injury group( P ﹤0.01),cell shrinkage,chromatin condensation,and nuclear fragmentation were seen,the intracellular SOD activity decreased while MDA content increased(P﹤0.01),and caspase 3 and HSP70 expression increased(P﹤0.01). Compared with H2 O2 group,the cell survival rate in VAP 20,40 and 80 mg·L-1 pre-treatment groups increased significantly(P﹤0.01),the apoptosis ratio declined from(25.3±1.0)% to (15.2±1.2)%,(10.3±0.9)% and(7.9±1.4)%(P﹤0.01),the SOD activity increased to 19.2±0.5,22.3± 1.7 and(24.9±0.6)kU·g-1 protein(P﹤0.01),MDA concentration decreased to 1.51±0.2,1.48±0.3 and (1.02±0.1)μmol·g-1 protein(P﹤0.01),and the expression of caspase 3 and HSP70 declined significant-ly(P﹤0.01). CONCLUSION VAP has exert protective effect on H2 O2-induced injury in vascular endothe-lial cells. The possible mechanism might be related to improvement of intracellular oxidative stress level.

Objective To investigate etiologies,treatment approaches and prophylaxis for delayed thoracostomach emptying in esophageal or gastric cardiac cancer patients treated with esophagogastrostomy.Methods We performed a retrospective review of the clinical data of 24 patients suffering delayed thoracostomach emptying among 1985 post-surgical patients with esophageal or gastric cardiac cancer from January 2000 to June 2011.Results Eighteen patients in the 24 patients were cured by conservative managements including endoscopic dilatation procedures.The remaining 6 patients were treated with surgery.Conclusion The main etiology of delayed thoracostomach emptying is gastroparesis,which can be treated with nonsurgical conservative approaches; whereas mechanical emptying disturbance requires surgery.Endoscopic examination appears to be the most important diagnostic approach in identifying and differentiating the etiologies of delayed thoracostomach emptying in post-surgical patients.Endoscopic dilatation procedure is proved to be effective for the treatment of delayed thoracostomach emptying in post-surgical patients in this study.

Objective To investigate changes in the number of endothelial progenitor cells (EPC) from peripheral blood and pathological feature in the development of transplant arteriosclerosis in mouse abdominal aortic allografts, and discuss their correlations. Methods A segment of abdominal aorta was transplanted orthotopically from C57BL/6 to Balb/c mice. The grafts were harvested at 3rd day, 2nd week, 4th week and 6th week after the operation and studied by light and electronic microscopy. Regional changes in the lumen and intima were measured with computer imaging analysis system. EPC from peripheral blood were quantified by flow cytometry. Results Endothelium injury and inflammatory cells infiltration were seen in the aortic allografts at 3rd day after transplantation.Neointimal lesions and acute rejection were observed as early as 2nd week after surgery. The lumen of allografts was significantly narrowed due to neointima hyperplasia and had progressed at 4th and 6th week postoperatively. The number of circulation EPC was increased from 1 st day after operation and reached the peak at 3rd day. Thereafter the number of EPC was decreased rapidly and significantly less at 14th and 28th day postoperation than that pre-operation. Conclusion Abdominal aortic transplantation from C57BL/6 to Balb/c mice presents typical pathological feature of transplant arteriosclerosis. The number of EPC from peripheral blood is related to the process of injured endothelial repair and neointima formation of aortic grafts. EPC count may be considered a novel biological marker and therapeutic intervention for transplant arteriosclerosis.

Objective To explore the effect of acupuncture combined with facilitated technique on lower limb function and activities of daily living of stroke patients.Methods 120 stroke patients with lower limb palsy were divided into the group Ⅰ (treated with acupuncture combined with facilitated technique), group Ⅱ (treated with acupuncture), third group Ⅲ (treated with facilitated technique) and the group Ⅳ (treated with medicine). The lower limb function and ADL of four groups were evaluated with Functional Ambulation Classification (FAC), Fugl-Meyer Assessment (FMA), Modified Barthel Index (MBI) before and 10 weeks after treatment.Results The scores of FAC, FMA and MBI of all the groups improved significantly, but it was more significantly in the first group than the in other groups (P<0.01), in group Ⅰ, Ⅱ, Ⅲ than in group Ⅳ (P<0.01). The difference between the group Ⅱ and Ⅲ was insignificantly(P>0.05).Conclusion Acupuncture combined with facilitated technique can improve the lower limb function and activities of daily living of stroke patients more effectively.
