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.

Objective To analyze the cause of acute brain swelling,brain encephalocele in brain traumatic injury craniotomy,and the reason,diagnosis and treatment methods of progressive epidural hematoma.Methods The clinical data of 381 patients with brain traumatic injury craniotomy were retrospetively analyzed.Of 318 patients,27cases had progressive epidural hematoma during operation.Results 9 cases died because of functional failure of brain stem,the other 18 cases were all clinically cured.Conclusion If acute brain swelling and encephalocele occured during operation,the cause should be found quickly,especially when there was skull fracture or epidural hematoma on the contralateral brain,the head CT and operation should be taken immediately,and the bulging brain tissue should not be removed blindly,and the skull should not be forced to close,otherwise the prognosis maybe poor.

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.

Objective To explore the value of the 64-slice spiral CT angiography(SCTA)in diagnosis of aortic disease.Methods 32 cases with aortic diseases confirmed by operation underwent 64-slice spiral CT enhanced scan,raw data were dealed with multiplanar reformation(MPR),curved plannar reformation(CPR),maximum intensity projection(MIP),volume rendering(VR)and advantage vessel analysis(AVA).Results The aortic disease in 32 cases included aortic dissection in 16 cases,pseudoaneurysm in 7 cases,true aneurysm in 4 cases,narrowing of the aortic arch in 3 cases and amputation of aortic arch in 2 cases.The endometrial break and mural thrombus better showed with MPR and the detecting rat of intimal flake and the initial break was 81%(13/16),while for the periphery thrombosis in 7 cases with pseudoaneurysm,the detecting rate was 100%(7/7).The showing rate for displaying the whole with CR was 100%(32/32).In showing calcification and accurate of vessels with MIP,the detecting rate was 84%(27/32).The showing rate of the extent of the disease and the relationship between peripheral vascular was 100%(32/32).AVA was of significance in the measurement of vascular diameter and vascular cross-sectional area,the showing rate was 44%(14/32).Conclusion 64-slice spiral CT angiography is of significance in diagnosing aortic diseases.

Objective　To investigate the actions of extra cellular medium in growth and differentiation of hair follicle and to look for growth adjusting factors for dermal papilla cells (DPC). Methods　Dermal papilla cells were isolated and cultivated with two steps method and the cells were identified by immunohistochemical staining for actin. Influence was examined on the adhesion and growth of dermal papilla cells by chondroitin sulfate A, chondroitin sulfate C and heparin sulfate. Results　Two steps method of enzyme digestion for isolating and cultivating dermal papilla cells was an efficient method and large amount of dermal papilla of high purity were harvested with this method. The method is very simple and easy to manege with. Increased adhesion and growth of dermal papilla cells were observed in specimen treated with chondroitin A and heparin sulfate. No significant effects was observed in the cells treated with chondroit in sulfate C. Conclusion　Some extra cellular medium can regulate the adhesion and growth of dermal papilla cells and therefore influence the growth and development of hair follicle.

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.
