OBJECTIVE:To investigate the effect of Xuebijing injection on coagulation function and prognosis in patients with sepsis. METHODS:50 patients with sepsis were randomly divided into control group and observation group according to the hospi-talization sequence,with 25 cases in each group. Control group received conventional treatment,and observation group was addi-tionally given Xuebijing injection(50 ml added into 5% Glucose solution or 0.9% Sodium chloride solution 250 ml intravenously, bid) on the basis of conventional treatment. Treatment course lasted for 7 d. The coagulation function,APACHE Ⅱscore after 7 days of treatment and 28 d mortality were compared between 2 groups. RESULTS:After 7 d treatment,the coagulation indexes were improved significantly in 2 groups compared with before treatment,and the APACHEⅡscores were decreased significantly in both groups;the observation group were significantly better than the control group,with statistical significance (P<0.05). After followed up for 28 d,the mortality rate of 2 groups were 16% and 28%,there was no statistical significance (P>0.05). CON-CLUSIONS:Xuebijing injection can inhibit blood clotting activation,correct the coagulation disorders,and improve the sepsis se-verity.

Aim To determine whether AngⅡin para-ventricular nucleus (PVN)was involved in the chronic intermittent hypoxia (CIH ) induced-hypertension in rats.Methods Male Sprague-Dawley rats were ran-domly divided into Sham and CIH groups,the Sham rats were exposed to continuous normoxia,while the CIH rats were submitted to CIH (8 h per day for 15 days).The conscious noninvasive method with tail cuff was performed in rats to record the systolic blood pres-sure during establishing the model of CIH induced hy-pertension.Mean arterial pressure (MAP)and heart rate (HR)were recorded in vivo on a PowerLab data acquisition system after CIH.Rats were fixed on the stereotaxic instrument to conduct microinjection in the PVN.We used Western blot to measure Ang Ⅱ level and AngⅡtype 1 receptor (AT1 R)protein expression in PVN.Results The level of PVN Ang Ⅱin CIH rats was significantly higher than that in Sham rats,a-long with increased AT1 R protein expression.Microin-jection of Ang Ⅱ(0.03,0.3,3 nmol)in bilateral PVN dose-dependently increased MAP in both CIH and Sham rats,and this response was significantly augmen-ted in CIH rats.Losartan (50 nmol),AT1 R antago-nist,had no effect on MAP in Sham rats,but caused significant MAP decreases in CIH rats,and prevented Ang Ⅱ-induced increases in MAP in both CIH and Sham rats.Conclusion The results suggest that the increased AngⅡrelease and enhanced AT1 R activation in the PVN contribute to CIH induced-hypertension in rats.

Objective To investigate the effects of continuous positive airway pressure (CPAP) on the levels of hemorheology and C-reactive protein in patients with obstructive sleep hypopnea apnea syndrome (OSAHS). Methods 58 moderate to severe OSAHS subjects were selected as treatment group and 32 healthyadults were selected as control group. Hemorheology and C-reactive protein in all subjects were examined and compared. The levels of hemorheology and C-reactive protein were also examined and compared before and after 3 months CPAP treatment in treatment group. Results In treatment group, the levels of the whole blood viscosity and hs-CRP were significantly higher than those in control group (P < 0.01). After treatment of CPAP for three months, the levels of the whole blood viscosity and hs-CRP obviously decreased (P < 0.01). Conclusion Levels of hemorheology and hs-CRP are elevated in patients with OSAHS and CPAP therapy could effectively decrease serum levels of hemorheology and hs-CRP in patients with OSAHS.

Object To evaluate the efficacy and toxicity of L-asparaginase based regimen for extranodal nasal type NK/T cell lymphoma (ENKTL).Methods 36 patients were treated with L-asparaginase based regimen from February 2008 to November 2011. 20 stage Ⅰ /Ⅱ patients were administered with VLD regimen based chemo-radiotherapy. 4 of 16 stage Ⅲ/Ⅳ patients received modified SMILE regimen chemotherapy, followed by involved field radiation therapy (IFRT), while others received modified SMILE regimen chemotherapy alone.Results Among 36 patients,35 were eligible for treatment response evaluation.The overall response rate (RR) was 68.6％ (24/35) with complete response (CR) rate of 54.3％ (19/35).After the median follow-up of 13.5 (range 3-31) months,for all patients,the 1-year overall survival (OS) rate was 82 ％,and the rate of progression-free survival (PFS) at 1 year was 65 ％.The patients who attained response with treatment showed better 1-year OS (93 ％) and PFS (80 ％) as compared with patients without response (35 ％; 33 ％),and the differences were statistically significant (x2=13.909,P =0.000; x2=8.216,P =0.004).The major adverse event was myelosuppression. No chemotherapy-related mortality occurred. Conclusion L-asparaginase based regimen is obviously effective and well tolerant for ENKTL. The large prospective clinical trials of L-asparaginase based regimen in the first-line treatment for ENKTL are worth for further investigation.

Objective To evaluate the clinical value of double-balloon enteroscopy( DBE)in as-sessing the effect of mucosal healing in patients with moderate small bowel Crohn's disease( CD)treated with low-dose azathioprine. Methods CD patients who were naive to any immunomodulators or biological a-gents with lesions mainly located in ileu were screened by multislice CT enterography and anal-route DBE at baseline. Lesions at 150 cm proximal to ileocecal valve were assessed by DBE with Simple Endoscopic Score for CD( SES-CD)after 12 and 24 months of low-dose azathioprine treatment,respectively. Results A total of 36 patients were enrolled and the average tolerated dose of azathioprine was(61. 8 ± 17. 2)mg/day. The total rates of complete,near-complete,partial and no mucosal healing in 36 patients were 19. 4%(7/36), 5. 6%(2/36),27. 8%(10/36),and 47. 2%(17/36)at month 12 and 30. 6%(11/36),25. 0%(9/36), 33. 3%(12/36),and 11. 1%(4/36)at month 24,respectively. The baseline SES-CD score(OR=2. 71, 95%CI:1. 11-6. 63,P=0. 029)and duration of disease(OR=1. 27,95%CI:1. 10-1. 47,P =0. 001) were two relevant factors associated with mucosal healing of small bowel CD. Conclusion DBE has a signif-icant advantage in assessing post-therapy mucosal healing for patients with small bowel CD. The optimal time point for the first follow-up by DBE is at least 12 months after low-dose azathioprine treatment.

Objective To explore the therapeutic effects of statin in patients with chronic obstructive pulmonary disease (COPD) in stable period. Methods 83 patients with COPD in stable period were recruited and randomly divided into two groups, treatment group (n = 41) and control group (n = 42).The control group received conventional routine therapy, and treatment group was given rosuvastatin calcium 20 mg once per day on the basis of routine treatment. The levels of sera C-reactive protein (CRP), pulmonary function (FEV1、FEVl%pred), and COPD assessment test (CAT) were observed at the time points of 0 week and 12th week, 24th week and 48th week were compared between two groups. Results At 12th week after the treatment, sera CRP levels, FEV1, FEV1%pred and CAT scores in either control group or treatment group showed some extent of improvements as compared to those at the time point of 0 week, and there was statistical difference of sera CRP levels and CAT scores between two groups (P < 0.05). There was no statistical difference of FEV1, FEV1%pred between two groups (P > 0.05) .24th week and 48th week after the treatment; sera CRP levels, FEV, FEV1%pred and CAT scores in two groups all significantly improved and were statistical different between two groups (P < 0.05). Conclusion Statin can alleviate inflammatory reaction, improve pulmonary function and life quality of patients with COPD.

Objective To investigate the value of double-balloon endoscopy (DBE) and multi-slice CT enteroclysis (MSCTE) in diagnosis of Crohn's disease (CD) in small intestine. Methods DBE and MSCTE were performed in 71 patients with suspected Crohn's disease in small intestine. The two methods were compared in terms of diagnosis, extents of disease, existance of complications and activity of the disease according to the pathologic findings and the outcome of follow-up. Results The diagnostic yields of DBE and MSCTE were comparable with no significant difference (χ2=2.29, P> 0.05). The positive and negative likelihood ratios were 22.5 and 0. 022 in DBE respectively, and were 1.6 and 0. 240 in MSCTE respectively. The results of DBE was consistent with MSCTE in diagnosis of mild bowel stenosis, but was inconsistent with MSCTE in diagnosis of moderate-severe bowel stenosis (χ2=11.298, P=0.001). The concordance of two methods in diagnosis of disease activity was 95.8%. Conclusions The first choice in diagnosis of small bowel CD is DBE. The combination of two methods will be helpful in diagnosis and evaluation of CD severity.
