Objective: To investigate the apoptosis-inducing effect of matrine on murine hepatocarcinoma cell line H22 in vivo and in vitro and explore the underlying mechanisms. Methods: The H22 cell apoptosis induced by matrine at the early stage was detected with Annexin V-FITC/PI double staining assay, The expressions of Bcl-2 and Bax proteins in H22 cells as well as in the BALB/c H22 xenograft tumor tissues were detected using immunohistochemical method. Transmission electron microscopy (TEM) was used to observe the ultramicro-structure alterations of H22 xenograft tumor cells in BALB/c mice. The effect of matrine on the kinetics of tumor growth after subcutaneous injection of H22 cells in BALB/c mice was observed and the tumor inhibition rate was calculated. Results: Annexin V staining detected early apoptosis of H22 cells after treatment with matrine 1.0 mg/mL and 1.5 mg/mL for 48 h. The apoptotic rates were 11.71% and 17.86%, respectively, both of which higher than that of control groups (P <0.05). The tumor inhibition rate was above 60% after matrine treatment. Immunohistochemistry analysis revealed that matrine increased Bax protein expression and reduced Bcl-2 protein expression in both H22 cells in vitro and xenograft tumor tissues in vivo. TEM demonstrated the existence of apoptotic cells and apoptotic bodies in H22 xenograft tumor tissues after matrine treatment. Conclusion: Matrine significantly suppresses tumor growth and induced apoptosis both in vitro and in vivo. The apoptosis-inducing effects is related with up-regulation of Bax protein and down-regulation of Bcl-2 protein.

Objective To elucidate the related risk factors for the cardiorenal syndrome(CRS),and to provide a reference for the prevention and treatment of CRS. Methods A retrospective study was conducted on 269 patients with chronic heart failure. The subjects were divided into two groups in accordance with estimated glomerular filtration rate(eGFR):patient group(CRS group),eGRF<60 mL/(min ! 1.73 m2)and control group,eGRF≥60 mL/(min!1.73 m2). The patients'general information as well as the related clinical lab indices and accessory examination indi-ces were collected. The risk factors for chronic heart failure and renal insufficiency were analyzed with multivariate logistic regression analysis. Re?sults The prevalence of chronic heart failure patients suffering from CRS was 26.39%. The single factor analysis showed that there were statistically significant differences between the two groups in terms of age,body weight,history of hypertension,and history of diabetes(all P<0.05). Compared to the control group,uric acid,cystatin C,serum urea nitrogen,brain natriuretic peptide,glycosylated hemoglobin,high-sensitivity C-reactive pro-tein,and left ventricular end-diastolic diameter in the CRS group were significantly higher;white blood cell count,hemoglobin,albumin,and left ventricular ejection fraction were significantly lower(all P<0.05). There was no statistically significant difference(P>0.05)between the two groups in regard to white blood cell count,glutamic-pyruvic transaminase,glutamic oxalacetic transaminase,cholesterol,triglycerides,high density lipoprotein,low density lipoprotein,troponin I,serum free triiodothyronine,serum free thyroxine,or thyroid stimulating hormone. Multivariate logis-tic regression analysis showed that older age,low body weight,history of hypertension,history of diabetes,hypoalbuminemia,superb sensitivity C-re-active protein levels,high uric acid,high cystatin C hyperlipidemia,and low ejection fraction were independently associated with the occurrence of CRS. Conclusion Older age,low body weight,history of hypertension,history of diabetes,hypoalbuminemia,high-sensitivity C-reactive protein levels,high uric acid,high cystatin C hyperlipidemia,and low ejection fraction are the high risk factors for CRS in heart failure patients and are inde-pendently associated with the occurrence of CRS. Early identification and control of these risk factors are important for the prevention and treatment of CRS.

Objective To study the preparation of volatile oils obtained from asarum and lily magnolia complexed with ?-cyclodextrin and hydroxypropyl-?-cyclodextrin in Xuetie Dingchuan plaster,and to study its impacts of transdermal absorption.Methods The volatile oil was complexed with ?-cyclodextrin and hydroxypropyl-?-cyclodextrin.GC method was used in the determination of volatile oils complexed with ?-cyclodextrin and hydroxypropyl-?-cyclodextrin to investigate the impacts of transdermal absorption.Results The accumulation transmission of the volatile oils complexed with ?-cyclodextrin was superior to that with hydroxypropyl-?-cyclodextrin.Conclusion The inclusion of volatile oils with ?-cyclodextrin can enhance drug penetration via skin.

Objective To investigate the prognosis and its influencing factors of post-encephalitic epilepsy ( PEE) .Methods Fifty viral encephalitis patients with PEE were followed up, which prognosis was observed by whether their no seizures for at least 1 year or not.The clinical data of patients was collected, and the relate risk factors on the poor prognosis of PEE were analyzed.Results The disturbance of consciousness and the seizure presence during acute encephalitis, more than ten seizures in poor prognosis group were much higner than the good one (all P<0.01).The age, sex, seizure type, dysphrenia and neurological defect in acute encephalitis, status epileptisus in acute encephalitis, abnormal EEG and abnormal head CT/MRI had no correlation with poor prognosis ( all P>0.05 ) .Multiple logistic regression analysis demonstrated that disturbance of consciousness during acute encephalitis、seizures presence in acute encephalitis were independent risk factors of poor outcome in PEE ( OR=7.269,95%CI:1.22 -43.35,P=0.029;OR =22.893,95%CI:4.02 -130.43,P=0.000).Conclusion Disturbance of consciousness during acute encephalitis, seizure presence in acute encephalitis both are the single risk factors of poor prognosis in PEE.

OBJECTIVE:To reduce the types of drugs which was not consistent with the accounts in monthly checking of out-patient department,reduce the wastage of dismounted drugs and improve dismounted drug management. METHODS:Through qual-ity control circle(QCC),analyzing the reasons for inconformity of accounts and drugs,adopting relevant countermeasures of staff training,cipher prescription,counter storage,managed by designated person,expiry data management and so on,the process of dismounted drug management was formulated and implemented. The types of drugs which was not consistent with the accounts and activity growth value of circle members were analyzed statistically before,during and after QCC. RESULTS:The types of drugs which was not consistent with the accounts were 33.6,21.2 and 13.6 before,during and after QCC,decreasing by 59.5%. The ac-tivity growth value of circle members were all positive value. CONCLUSIONS:QCC of outpatient pharmacy can effectively reduce the types of drugs which is not consistent with the accounts in monthly checking,standardize dismounted drug management and im-prove pharmaceutical care quality.

Innate immunity is on the frontline of fight against pathogenic microorganism invasion .As a DNA sensor, absent in melanoma 2 (AIM2) is an important member of innate immune system.It can recognize dsDNA of pathogenic microbes to form AIM 2 inflammasomes , which facilitates defending and clearing the invasion of pathogens by activating caspase-1 dependent pyroptosis and the mature of IL-18 and IL-1β.AIM2 inflammasomes play an important part in responding to Listeria monocytogenes, Francisella tularensis, Streptococcus pneumoniae, Mycobacterium tuberculosis, Aspergillus fumigatus, vaccinia virus , murine cytomegalovirus , and hepatitis B virus infections .This paper introduces the components of AIM 2 inflammasomes and summarizes its function in defending the invasion of pathogenic microorganisms .
