Objective To investigate the effects of Pravastatin on serum oxidative modified LDL (ox-LDL), tumor growth factor ?1 (TGF-?1), vascular cell adhesion molecule-1 (VCAM-1) and lipid levels in patients with acute cerebral infarction(ACI).Methods 114 cases with ACI were randomly divided into two therapy groups: (1) 56 cases were given Pravastatin combined with Aspirin;(2) 58 cases were treated with Aspirin only. The serum levels of ox-LDL, TGF-?1, VCAM-1 and lipid were detected 72 h after the onset of the disease and 3 months following the treatment. Meanwhile, the same were detected in the control group (50 healthy people). Results Within 72 h, the serum levels of ox-LDL, VCAM-1, cholesterol and LDL were higher in patients with ACI than those in control group(all P

Objective To systematically evaluate the effectiveness and safety of renal sympathetic denervation (RSD) for treatment of patients with resistant hypertension.Methods English and Chinese literatures of controlled clinical trials on RSD in treatment of resistant hypertension were searched from the Cochrane Library,PubMed,Web of Science,Wanfang Database and CNKI up to February 2013.Metaanalysis was performed with the selected studies by using software Rev.Man 5.0.Results Seven studies involving 354 cases with RSD and 146 controls were included for analysis.Compared with control group,RSD significantly lower both systolic and diastolic blood pressure in patients with resistant hypertension (systolic,1 month:MD =-18.04,95％ CI:-19.94--16.14,P ＜0.01; 3 months:MD =0.01,95％CI:-28.10--17.98,P＜0.01; 6 months:MD=-25.59,95％CI:-34.08--17.11,P＜0.01; diastolic,1 month:MD=-7.53,95％ CI:-8.60--6.45,P＜0.01; 3 months:MD =0.01,95％CI:-12.5--4.47,P ＜ 0.01; 6 months:MD =-10.54,95％ CI:-16.44--4.63,P =0.000 5).In addition,there was no significant difference in adverse reactions between RSD treatment group and control group (OR =1.13,95 ％ CI:0.34-3.76,P =0.84).Conclusions Renal sympathetic denervation can effectively reduce blood pressure in patients with resistant hypertension 1-6 months postoperatively,without increase of adverse reactions.The long-term efficacy and safety need to be further observed.

Objective To evaluate the efficacy of percutaneous transluminal septal myocardial ablation (PTSMA) and septal myectomy (SM) for treatment of hypertrophic obstructive cardiomyopathy.Methods We searched all clinical controlled trials of PTSMA and SM in treatment of hypertrophic obstructive cardiomyopathy in Cochrane Library,PubMed,Web of Science,Wanfang Database and CNKI update to August,2012.The selected studies in Chinese and English were used for Meta-analysis with software RevMan 5.0.Results Five studies including 286 cases (PTSMA:149,SM:137) were included in the study.Left ventricular outflow tract pressure was significantly reduced by SM treatment compared with PTSMA (OR =9.07,95％ CI:0.96-17.18,P =0.030).There were no significant differences in interventricular septum thickness (OR =1.15,95％ CI:-0.79-3.10,P =0.240),left atrial diameter (OR =1.95,95％ CI:-0.16-4.07,P =0.070),left ventricular end-diastolic (OR =0.70,95％ CI:-0.79-2.19,P =0.360),end systolic diameter (OR =1.14,95 ％ CI:-1.65-3.93,P =0.420),degree of symptom improvement (chest pain:OR =1.07,95 ％ CI:0.35-3.23,P =0.910;syncope:OR =0.32,95％ CI:0.08-1.23,P =0.100),and postoperative mortality (OR =1.63,95％CI:0.46-5.76,P =0.450) between PTSMA and SM treatment; but the rates of pacemaker implantation (OR =5.91,95％ CI:2.04-17.11,P =0.001) and reintervention treatment (OR =6.62,95％CI:1.20-36.62,P=0.030) in patients with PTMSA were significantly higher than those with SM.Conclusions There is no evidence to indicate that PTSMA can completely replace SM,as an alternative choice the therapy can be used according to left ventricular out flow tract pressure,symptoms,anatomy of target vessel and other conditions.

ObjectiveTo evaluate the clinical efficacy and safety of astragalus injection on the immune function in patients with senile sepsis.Methods Sixty patients with old age sepsis in Critical Care Medicine Department of Guangdong Provincial Traditional Chinese Medicine Hospital were enrolled and randomly assigned into control and treatment groups according to the table of random numbers, 30 cases in each group. According to 2012 sepsis guidelines for treatment, including antibacterial drug, mechanical ventilation, visceral function support, etc., the therapy was given to the control group; besides the treatment in the control group, intravenous drip of 60 mL astragalus injection(10 mL per ampoule) in 250 mL 0.9% normal saline was additionally given in the treatment group, once a day for 7 days. Before and after treatment, the immunological indexes, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, sequential organ failure assessment(SOFA) score, duration of mechanical ventilation and time of stay in intensive care unit(ICU), 28-day mortality and adverse drug reactions were compared between the two groups.Results Before treatment, there were no statistically significant differences in CD3+, CD3+CD4+, CD3+CD8+ and T helper cells /T suppressor cells(Th/Ts)levels between the two groups(allP>0.05), while CD3-NK+ of the control group was significantly higher than that in the treatment group〔(10.47±6.22)% vs. (6.26±4.13)%,P<0.05〕. After treatment in treatment group, CD3+, CD3+CD4+ and CD3-NK+ were increased, CD3+CD8+,Th/Ts were decreased compared with those before treatment; in the control group after treatment, CD3+,CD3+CD8+ and CD3-NK+ were decreased and CD3+CD4+ and Th/Ts increased compared with those before treatment. In the comparisons between the treatment group and control group after treatment, the differences in CD3+, CD3+CD4+ and CD3+CD8+ had statistical significance〔CD3+:(30.30±17.17)% vs.(41.91±22.29)%, CD3+CD4+:(31.54±13.24)% vs.(40.08±15.28)%, CD3+CD8+:(14.25±8.10)% vs.(9.52±9.33)%,allP<0.05〕; while the differences in Th/Ts and CD3-NK+ had no statistical significance(bothP>0.05). After treatment in the treatment group, IgG was increased compared with that in the control group〔IgG(g/L): 13.07±5.43 vs. 10.10±3.96,P<
0.05〕. The differences in IgA, IgM, complement(C3,C4) and total serum complement activity(CH50) in the comparisons between the two groups had no statistical significance after treatment(allP>0.05). The differences in APACHEⅡ score(13.83±6.18 vs. 15.90±7.48), SOFA score(7.38±4.66 vs. 6.89±4.19), time of stay in ICU(day: 11.63±5.13 vs. 13.62±8.08), invasive ventilation time(hour: 155.44±119.68 vs. 224.08±174.15) and noninvasive ventilation time(hour: 55.55±42.24 vs. 98.57±43.17) had no statistical significance in comparisons between the treatment group and control group after treatment(allP>0.05). The difference in 28-day mortality had no statistical significance in comparison between the treatment group and control group〔16.7%(5/30) vs. 20.0%(6/30),P>0.05〕. In 60 cases, there were 2 patients with adverse drug reaction, one diarrhea and another little rashes, the rest of the patients did not appear any drug side effect.ConclusionAstragalus injection combined with conventional western medicine therapy possibly has certain effect on adjustment of disturbance of immunologic functions in old patients with sepsis, and its therapeutic safety is well.

Mitochondrial dysfunction plays an important role in the process of PD, DJ-1 participates in regulating the function of mitochondria,which has an effect on the protection of mitochon-dria. DJ-1 mutations can lead to the decrease of the activity of mitochondrial complex Ⅰ, the decrease of mitochondrial mem-brane potential and then mitochondrial fragmention and mitoph-agy, and then further damage neurons and trigger PD. This re-view presents the role of DJ-1 in regulating the function of the mitochondria in the pathogenesis of Parkinson's disease(PD).

Objective To establish a malignant transformed human fetal osteoblastic human cells from the immortalized cell line hFOB1.19 in order to explore the molecular mechanism in tumorigenesis of osteosarcoma. Methods hFOB1.19 cells were treated sequentially by an initiated factor, N-methyl-N’-nitro-N-nitrosoguanidine (MNNG) and a promoter, 12-O-tetradecanoyl phorbol-13-acetate (TPA). The features of malignancy of transformed cells were identified by cell morphology, DNA content analysis, colony forming frequency on soft agar and tumorigenetic test in nude mice. Results Continuous passaging after the treatments resulted in the formation of a few paramorph foci and exhibited in an extensively random orientation. The poly-ploid of DNA was 81.08% in experiment group, much higher than that in control group (55.03%). Compared with that of negative control cell, colony formation efficiency of transformed cells in semisolid agar showed a a significant increase. The transformed cells formed tumors subcutaneously in the nude mice, which were verified to be poorly differentiated osteosarcoma histopathological examination. Conclusion Mocking the process of malignant transformation of human cells, we establish malignant transformed immortalized human fetal osteoblastic human cells (hFOB1.19) model.

Objective To evaluate effect of en bloc resection of malignant sacral tumor involving partial sacrum and ipsilateral sacroiliac joint with reservation of contralateral sacral foramina.Methods Between February 2005 and July 2010,16 patients with malignant sacral tumor involving partial sacrum and ipsilateral sacroiliac joint underwent hemi-sacrectomy and functional reconstruction.The operation achieved en bloc resection of tumor with reservation of contralateral sacral foramina.There were 10 males and 6 females,aged from 17 to 70 years (average,37.9 years).There were 5 cases of chondrosarcoma,3 cases of Ewing's sarcoma,2 cases of malignant schwannoma,2 cases of osteosarcoma,1 case of malignant giant cell tumor of bone,1 case of lymphoma and 2 cases of metastatic tumor.Results The surgical time ranged from 4 to 11.5 hours (average,6.5 hours).The average blood loss was 3600 ml (range,1500 to 5500 ml).Five patients underwent type Ⅰ resection,while 11 patients underwent type Ⅱ resection.All patients were followed up for 21 to 59 months (average,34.4 months).Three months after operation,13 patients had difficulty with ankle plantar flexion,while sphincter function was more or less reserved in 16 patients.Four patients (25％)had wound healing complications,which was cured after debridement and drainage.Local recurrence occurred in 7 patients.There were 5 cases of local recurrence among 6 patients who had intralesional margin;4 recurrence lesions located in the sacrum and 1 in soft tissue.Eight patients (50.0％) survived without tumor,2 patients (12.5％)survived with tumor,and 6 patients (37.5％) died of tumor.Conclusion The en bloc resection of tumor involving partial sacrum and ipsilateral sacroiliac joint with reservation of contralateral sacral foramina was feasible and had better outcome compared with total sacrectomy.

Objective To analyze the feasibility and the diagnostic yield of double-balloon enteroscopy (DBE) examinations for small bowel bleeding (SBB). Methods A retrospective analysis was conducted on 52 cases with small bowel bleeding between June 2015 and July 2016,and all was treated with DBE. therapeutic outcome, complications and follow-up were compared. Results The study included 52 patients (28 males and 24 females) with an average age of (51.0 ± 17.0) years (16~82 years) and onset time (8.3 ± 4.0) days (1~14 days) . 25 using oral route and 21 using the anal route, 1 using the colon ifstula route, a combination of using oral and anal (n=4).The bleeding source was identiifed in 40 of 52 patients (76.9%), complication rate was 5.8%(3/52), and rebleeding rate was 16.7%(2/12). The endoscopic treatments included polypectomies (n=5), argon plasma coagulation (APC, n=2), surgical treatment (n=14, 26.9%), and foreign-body extraction (n=1). Patients were diagnosed with the following:tumors (n=9, 17.3%), ulcers (n=9, 17.3%), Crohn’s disease (n=7, 13.5%), polyps (n=5, 9.6%), diverticulum (n=4, 7.7%). Patients with small bowel bleeding were followed up for a mean period of (8.3±2.0) months (range 4~10 months), 2 deaths were dying from small bowel cancer. Conclusions DBE is a safe endoscopic technique for patients with small bowel bleeding and can be safely carried out even after Roux-en-Y operation. Tumors, ulcers and Crohn’s disease are very common causes of SBB. The rebleeding rate after a negative DBE is considerable, especially small bowel vascular lesions.
