Objective To investigate the effect of Xuebi-jing injection on the change of the serum high-sensitivity C-reactive protein (hs-CRP) in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD). Methods 86 patients with AECOPD were enrolled in this study, who was randomly divided into a control group (43 cases)and a treatment group (43 cases). Both treatment group and control group were given conventional therapy. On this basis, Xuebi-jing injection was added to the treatment group. Hs-CRP, blood gas analysis, blood cell count and severity of illness score (acute physiological and chronic health evaluation Ⅱ, APACHE Ⅱ) were monitored before and 5 days after treatment. Results There was no obvious difference of hs-CRP levels between two groups before treatment. Hs-CRP was decreased in both groups after the treatment, while the treatment group showed an obvious decrease compared with the control group (t＝5.3302,P＜0.01). Blood gas analysis, blood cecount, APACHE Ⅱ scores were improved after the treatment in both groups, while the improvement in treatment group showed obvious difference than the control group (t＝13.5089、26.3077 、13.4053,P＜0.01). Conclusion The conventional therapy plus Xuebi-jing injectiong for AECOPD can improve serum hs-CRP levels and improve the efficacy of AECOPD .

Recently the research of vaccines and drugs against anthrax is one of hot spots. The efficacy of anthrax vaccines and drugs can't be experimented in human, therefore the testing model is very important. The cell models mainly include CHO and J774A.1. Now, various kinds of animals including mice, rats, rabbits, and nonhuman primates were experimented as animal models. Because the models are different, the results of experiments are significantly different, sometimes they are contrary. Many experiments of Bacillus anthracis in different cell and animal models are reviewed, and the principles of choosing animal models of anthrax are discussed. In order to analyze the different results of experiments in different models, the pathogenesis of Bacillus anthracis and the researching progress of anthrax vaccines and drugs are also simply introduced .

Objective Evaluate the diagnostic value of PET/CT in the preoperative advanced gastric carcinoma comparing with mult;-slice spiral computed tomography. Methods Thirty-nine advanced gastric carcinoma patients taking PET/CT and abstract 40 advanced gastric carcinoma patients performing MSCT before operation,were done the TNM staging, and the Results were compared with the operation histopathology. Results For diagnosing primary lesions, regional lymph nodes, N3 lymph nodes ,PET/CT was accurate in 92.3% , 66.7% and 100.0%.Instead, MSCT was accurate in 82.0% , 50.0% and 62.5%. Conclusions (1) PET/CT and MSCT have high accuracy in diagnosing primary lesions and regional lymph nodes. But for detecting the N3 lymph nodes and distant metastasis, PET/CT has higher accuracy than MSCT. PET/CT combining abdominoscopy may decrease or avoid exploratory laparotomy.

Objective To investigate the clinical effects of the posterior atlantoaxial pedicle screw fixation combined with unilateral axial spinous process and lamina screws and allogeneic bone graft for atlantoaxial instability.Methods From March 2010 to April 2014,data of 10 patients with atlantoaxial instability who had undergone atlanto-axial vertebral pedicle fixation and interbody fusion combined with posterior atlanto-axial spines lamina nails were retrospectively analyzed.There were 6 males and 4 females with an average age of 39 (range,16-62) years old.The inclusion criteria was atlantoaxial instability together with unilateral vertebral artery segment high cross deformity (7 patients) or atlantoaxial joint break bad involving unilateral pedicle (7 patients).3 patients have spinal cord disease symptoms and physical signs,both suffered limited neck mobility and pain.The VAS scores were 1-8,with an average of 3.70±2.11.Preoperative X-ray,CT three-dimensional reconstruction and MRI were collected.X-ray and CT examination were performed 7 d and 1,3,6,12 months after operation to evaluate the internal fixation and bone grafting fusion.Results There's no occurrence of cervical spinal cord and vertebral artery injury.Screws were successfully implanted.1 case's incision occurred infiltration liquid 3 days after operation.For allograft rejection consideration,we changed the plan,and the infiltrating stopped 5 days later.Other incisions were all primary healing.VAS scores were 1.01±0.89 after operation,which was significantly reduced.X-ray showed good recovery of cervical sequence after the operation,and CT revealed 1 patient with atlas pedicle screw in the medial cortex damage.Spinal canal was without infringing,and the other screw positions were normal.6 months after operation,X-ray or CT examination both showed bony fusion.Conclusion Atlantoaxial pedicle screw fixation combined with unilateral axial spinous process and lamina screws and allograft bone graft fusion for the treatment of atlantoaxial instability can observe good clinical effects.

Objective To observe the expression changes of peripheral endothelial progenitor cells (EPCs) and Ang-1/Tie2 in patients with pulmonary arterial hypertension (PAH).Methods From Jun 2011 to Dec 2012,45 patients with PAH charged in Affiliated Hospital of Hangzhou Normal University were divided into 3 groups according to mean pulmonary arterial blood pressure (15 per group):mild(Group L),moderate(Group M),and severe(Group S),with another 15 normal people as control group(Group C).The EPCs were isolated from peripheral blood of every patient,number counting using fluorescence activated cell sorter (FACS),function test using cell culture in vitro.Expression of Ang-1 and Tie2 in the peripheral EPCs were measured by RT-PCR or Western-blot.Non normal data was analyzed by non parametric statistical test.Results The statistical discrepancy existed among Group L,M,S and the control in the number of EPCs [32.0 (27.0,37.0),26.0 (19.0,31.0),24.0 (22.0,26.0) vs 40.0 (37.0,51.0),P ＜ 0.05].The ability of migration [32.1 (26.5,37.5),26.8 (22.4,35.4),21.0 (17.8,34.0) vs 39.0 (33.3,42.4),P＜0.05] and adhesion of the EPCs [57.1(50.9,61.8),51.8(45.2,58.7),46.0 (37.2,55.1) vs 64.1 (56.2,75.0),P ＜ 0.05] among study groups and control group was different in statistic,the same with the proliferation activity of EPCs in different groups [0.6 (0.5,0.7),0.5 (0.4,0.6),0.4(0.3,0.5) vs 0.7(0.6,0.8),P ＜0.05].The mRNA expression of Ang-1 and Tie2 in Group M & S were significantly reduced compared with control [4.33 (2.49,4.62) and 2.89 (2.39,3.44) vs 5.31(3.78,6.22),P＜0.05],Tie2 mRNA[1.32(1.23,1.34)and 1.23(1.08,1.42)vs 1.49(1.25,1.66),P ＜ 0.05],and the protein expression of the phosphorylated Tie 2 in Group M &S were decreased [0.16 (0.15,0.24) and 0.12 (0.08,0.18) vs 0.22 (0.19,0.28),P ＜ 0.05].No significant difference of Ang-1 and Tie2 expression was observed between Group L and control [5.42 (4.72,5.95),1.54 (1.43,1.66) and0.23(0.19,0.33),P=0.674,0.867 and 0.674].Conelusion With the severity of PAH,the number and function of circulating EPCs decreased,as consistent with Ang-1 and Tie2 expression changes,suggesting that function decrease of EPCs in patients with PAH may be associated with the decrease of Ang-1/Tie2 expression.

Objective To determine the expression and clinical value of neuropilin-1 (NRP-1) in hepatocellular carcinoma (HCC).Methods One hundred and fifty-one cases of HCC tissues and 89 cases of healthy liver tissues were chosen to compare the expression of NRP-1 by immunohistochemistry.Then the relationships between different clinical factors and the expression of NRP-1 were analyzed by univariate and multivariate statistical analysis.Moreover,the survival rates were compared by survival analysis between different expressions of NRP-1 in HCC patients.Results Eleven cases were lost to follow-up or died for non HCC disease,and the effective cases in the final study were 140 cases.The positive expression rates of NRP-1 in HCC and normal liver tissues were 65.00％ and 35.96％ respectively,and the difference was statistically significant (x2 =18.843,P ＜0.001).According to the expression level of NRP-1,140 patients with HCC were divided into negative expression group (n =49) and positive expression group (n =91).Univariate analysis showed that the expression of NRP-1 in HCC was correlated with tumor number (x2 =8.025,P =0.005),TNM stage (x2 =26.467,P ＜ 0.001),differentiation degree (x2 =15.296,P ＜ 0.001),portal vein invasion (x2 =9.054,P =0.003) and hepatic vein invasion (x2 =5.928,P =0.015).Multivariate statistical analysis showed that TNM stage (OR =1.392,95％ CI:1.121-1.730,x2 =8.950,P =0.003),differentiation degree (OR =1.469,95％ CI:1.102-1.958,x2 =6.862,P =0.009),portal vein invasion (OR =1.829,95％ CI:1.157-2.893,x2 =6.665,P =0.010) and hepatic vein invasion (OR =2.161,95％ CI:1.172-3.987,x2 =6.084,P =0.014) were important factors for NRP-1 expression.The median survival time of NRP-1 negative HCC patients was significantly longer than that of positive group (44 months vs.23 months),and the difference was statistically significant (x2 =21.922,P ＜0.001).Conclusion NRP-1 is over-expression in HCC tissue and related to the malignant progress of HCC,and this suggests poor prognosis in patients with HCC.

OBJECTIVE:To explore the clinical efficacy and safety of oxymatrine membrane,rhEGF gel respectively com-bined with Yunnan baiyao for postoperative cervical wound after LEEP. METHODS:300 patients with cervical intraepithelial neo-plasia(CIN)Ⅱ and Ⅲ were divided into group A,B,C(100 cases in each group)based on CIN grading and stratification and random sampling in each stratification. After conventional LEEP,patients in group A were cleaned the wound by 0.9% Sodium chloride injection,spraying Yunnan baiyao powder,once only after surgery;patients in group B were additionally given recombi-nant human epidermal growth factor (rhEGF) on the basis of group A,once every week after surgery,for 3 weeks;patients in group C were additionally given oxymatrine membrane on the basis of group A,1 tablet every evening after surgery,for 2 weeks. Postoperative bleeding,bleeding duration,rebleeding and duration after postoperative bleeding stopped,postoperative drainage du-ration,the incidence of adverse reactions in 3 groups were observed. RESULTS:The patients of postoperative bleeding,bleeding time ≥7 d and rebleeding after stopping bleeding in group B were significantly lower than group A;the incidence of bleeding time ≥7 d in group C was significantly lower than group A,the proporition of postoperative drainage duration for less than 7 d was significantly higher than group A,for 8-13 d was significantly less than group A;early wound healing rate in group B and group C were significantly better than group A,with statistical significances (P<0.05). There were no significant differences in above-mentioned indexes in group B and group C(P>0.05),and there were no obvious adverse reactions in 3 groups. CONCLU-SIONS:Oxymatrine membrane and rhEGF gel respectively combined with Yunnan baiyao have better healing than Yunnan baiyao alone,do not increase the incidence of adverse reactions,while there is no significant difference in oxymatrine membrane and rhEGF gel.

This study was designed to investigate the correlation between autophagy and polarization of macrophages in atherosclerosis (AS) plaque in arteriosclerosis obliterans amputees. Femoral artery specimens from arteriosclerosis obliterans amputees were performed hematoxylin and eosin (HE) staining, oil red O and immunofluorescence staining to observe the morphology of atherosclerotic plaque, phenotype of macrophages and autophagy in plaque; using real-time quantitative RT-PCR technology to detect the mRNA level of M1 and M2 type markers in arterial tissue; to analyze polarized signal pathway and autophagy protein levels in macrophages by Western blotting. Arterial specimens staining showed obvious lipid deposition and obvious infiltration of amount of foam cells and inflammatory cells. Macrophages were mainly expression M1 type in percentage in fibrous plaque. Although both M1 and M2 macrophages were upregulated in atheromatous plaque, the increase was dominant in M2 type in percentage. The level of autophagy was significantly higher in the atheromatous plaque than that of fibrous plaque. The expression of tumor necrosis factor- α (TNF-α), monocyte chemotactic protein-1 (MCP-1), inducible nitric oxide synthase (iNOS), interleukin-6 (IL-6) and interleukin-12 (IL-12) mRNA was significantly higher in fibrous plaque than that of atheromatous plaque (P < 0.01 or 0.05), and arginase-1 (Arg-1), transforming growth factor-β (TGF-β), CD163 and interleukin-10 (IL-10) mRNA was significantly lower than that in atheromatous plaque (P < 0.01). The levels of p-STAT1 and NF-κB were significantly increased in fibrous plaque (P < 0.01), while p-STAT6 expression was significantly increased in atheromatous plaque (P < 0.01). The level of LC3-II was significantly higher in atheromatous plaque than that in fibrous plaque (P < 0.01). Macrophages in early atherosclerotic plaque were induced to M1 type through p-STAT1/NF-κB pathway and expressed moderate levels of autophagy; while macrophages in advanced plaques were induced to polarization of M2 type through p-STAT6 pathway. M2 macrophages expressed a higher level of autophagy than M1 macrophages.
