Objective:To study and promote the quality standard for Shuangbai Quyu powder. Methods:A microscopic identifi-cation method was performed to identify Phellodendri amurensis cortex, Rhei radix et rhizoma, Platycladi cacumen and Andrographis herba. TLC was performed to identify Phellodendri amurensis cortex, Andrographis herba and Rhei radix et rhizoma. HPLC was used to determine the content of berberine hydrochloride in Phellodendri amurensis cortex. and the lower limit was determined. Results: The microscopic identification method was simple. The spots in TLC were distinct without any interference from the negative coutrol. Ber-berine hydrochloride had a good linear range of 0. 010-0. 400 μg(r=0. 999 9). The average recovery was 99. 51%, and RSD was 0. 31% (n=6). Conclusion:The method can be used for the quality control of Shuangbai Quyu powder effectively,which is beneficial to the quality standard promotion of hospital preparations.

Objective To investigate the imaging features of Budd-Chiari syndrome(BCS) on 64 slice spiral computed tomography(64SCT) and the diagnostic value of 64SCT for BCS.Methods Twenty-nine patients diagnosed as BCS by 64SCT were retrospectively included into this study and all the patients were researched by digital substraction angiography(DSA).Two abdominal radiologists analyzed the CT imaging features of BCS,paying attention to the vascular lesion,the morphology abnormality of the liver and the degree of portal hypertension,with review of DSA findings.Results ①The accuracy of 64SCT for BCS was 93.1%(27/29),and there were 2 false positive cases and no false negative case.The accuracy of 64SCT for those patients with thrombosis of inferior vena cava(IVC) and(or) hepatic vein(HV) was high as compared to those with stenosis of IVC and(or) HV.②The morphology abnormality of the liver included hepatomegaly(24 cases),low attenuation(27 cases) and inhomogeneous pattern of parenchymal contrast enhancement(5 patients in arterial phase and 19 patients in portal vein phase).③The images of all the patients showed the features of portal hypertension.Conclusion The accuracy of 64SCT for BCS is satisfactory and the false negative is seldom.The 64SCT could accurately display the morphology abnormality of the liver and the compensatory circulation in BCS patients.For those patients with stenosis of IVC and(or) HV,however,the diagnostic power of 64SCT is limited.

Bone marrow-derived mesenchymal stem cell (BMSC) transplantation is one ot the most popular therapeutic measures in severe acute pancreatitis (SAP). However, technical challenges and ethical concern have hindered its clinical application. Paracrine factor, as a new safe and easy handing therapeutic measure, can work comparably effective as BMSC transplantation in SAP therapy, but bio-safe risks could be greatly reduced. In this paper, we reviewed the therapeutic effect and potential mechanism of paracrine factors in the treatment of SAP. The injection of paracrine factors yielded from cultured cell suspension will be a new cell therapeutic measure for SAP.

Objective To investigate the clinical characteristics of pontine infarction and the value of MRI in diagnosis of pontine infarction. Methods The cilinical feature and image manifestation of 65 cases with pontine infarction were analyzed retrospectively. Results Pontine infarction had complicated clinical presentation,classical syndrome was less,most presentation was similar to anterior circulation infarction. MRI especially DWI could found the infarction lesions earlier. Conclusion Pontine infarction and anterior circulation infarction have simlar presentations.MRI especially DWI could show the infarction lesions in supper-acute stage,could be helpful to diagnose.

Objective To report the clinical, myopathological and genetic features in myofibrillar myopathy (MFM) with numerous cytoplasmatic-spheroid bodies. Methods Ten patients in 5 successive generations began to present progressive proximal limbs weakness at 35 to 40 years old. Additionally, 4 cases manifested diarrhea and 6 cases accompanied with cardiorespiratory symptoms. An open biopsy was performed on the proband. In addition to histological, enzymhistochemical staining and ultrastructural examination, immunohistochemical staining with antibody against tau, desmin, ubiquitin, dysferlin, dystrophin-C', dystrophin-N' and dystrophin-R were done. All the exons of the MYOT, CRYAB, DESMIN, LDB3, LMNA, SEPNI gene and the FLNC exon 48 were analysed. Results Cytoplasmatic bodies and spheroid bodies were found in the fibers. The deposited material were positive for tau, desmin, ubiquitin, dysferlin and dystrophin-R, dystrophin-C'. Electron microscope showed granular dense Z-disc material in the inclusions which were surrounded by thin filament. There was no mutation in the above exons of the 7 candidate genes. Conclusions Myofibrillar myopathy involves multiple system impairment. Cytoplasmatic and spheroid bodies contain microtubule and membrane associated protein. The disease might be induced by some unknown genetic abnormities.

Objective To investigate the infection of Xuebijing injection on inflammatory factor of large sized avulsion patients.Methods 70 patients being selected with large sized avulsion were randomly recruited into a treatment group(35 patients)and a control group(35 patients).The control group received traditional comprehensive treatment.On this basis,Xucbijing injection was injected to the treatment group on admission day,and Xuebijing injection 50 ml in 0.9%NaCl solution 100 ml was,intravenously infused for 60 min once,2 times daily,up to 7 d.TNF-α,IL-6,CRP,WBC and NEU%of the two groups were respectively detected before treatment and 7 days after the treatment.Exudation of wound surface was also observed.Results After 7 days of treatment,there was significant difierence in the treatment group compared with pretreatment(P<0.01).There was statistical difference between two groups after 7 days of treatment(P<0.01).Exudation of wound surface of the treatment group was less than the control group's.Conclusion Xuebijing injection has antagonistic effect on inflammatory factor of large sized avulsion patients and can lessen exudation of wound surface.

Objective The aim of this study was to assess the current situation and master degree on medical statistics among the medical correlation personnel, in order to provide useful information for transformation of education towards the medical correlation personnel . Methods Using cluster random sampling method to select 358 the medical correlation personnel who were recruited from health institutions in Chongqing to respond to the questionnaires. Questionnaire including respondent basic information, statis-tical knowledge and statistical knowledge needs. The data of the survey were analyzed by chi-square test, descriptive statistics analysis. Results 94.7% of the surveyed used statistical knowledge in the process of work or study. The main concentration of medical statistical knowledge utilization rate, the proportion of receive professional education or training courses of medical statistics and the willingness to participate in specialized training of medical statistics is 20-30 age group, No Title group, Master and over group andStudents group. As for ten categories of common statistical methods, thirty percent of people can use them skillfully, but the majority of the more advanced statistical analysis methods cannot be used or have never heard of. The greatest demand for learning ten kinds of common statistical methods is calculating cor-rectly through statistical software. Conclusion The vast majority of medical personnel need to use medical statistics in the actual work and study, but they have a lower mastery of statistical methods. Therefore, we should strengthen the medical statistics teaching and training for medical personnel.
