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 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 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 investigate the role of double-balloon enteroscopy (DBE) in the evolution of detection and surgical treatment of small bowel stromal tumors (SBSTs),based on nine years experience.Methods In this retrospective study,193 patients with localized SBSTs were divided into the CT-enterography (CTE) and/or DBE group (n =100) and conventional modalities group (n =93).These patients were further divided into the open surgery group (n =126) and laparoscopy-assisted resection group (n =67).The development of clinical diagnosis and surgical treatment strategies were compared before and after the introduction of DBE.Results The average age and tumor size were significantly smaller in the CTE and/or DBE group than those in the conventional modalities group,respectively (age:50.9 ± 12.1 vs.56.9 ± 11.6 years; tumor size:3.6 ± 1.3 vs.6.1 ± 2.6 cm,P ＜ 0.01).Before the introduction of DBE (from January 2001 to December 2002),all patients underwent conventional modalities,and only 4 cases/year for open surgery.Afterward,from January 2003 to December 2004,84.6％ (11/13) of SBSTs were detected by DBE.From January 2005 to December 2008,50.0％ (23/46) of SBSTs were found by CTE combination with DBE.From January 2009 to December 2011,80.5％ (33/41) of SBSTs were diagnosed by CTE,and the number of patients underwent operation increased up to 25 cases/year,which was nearly 5.3 folds higher than that before the introduction of DBE.Sixty-seven patients were successfully operated by laparoscopy-assisted resection,82.1％ (55/67) of them were detected by CTE ands/or DBE,89.1％ (49/55) of whom had low-or intermediate-risk SBSTs.Conclusion DBE plays an important role in optimizing the algorithm of detection and treatment of SBSTs.

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.
