Objective To find the mechanism of traditional Chinese medicine Heshouwuyin(HSWY) in anti-aging in ovary of the aging model rats,so as to provide theoretical and experimental evidence to anti-aging in female sexual gland.Methods Thirty-six rats were divided into three groups at random: normal group,aging model group,prevent aging group.Rats the in prevent aging group were subdivided into four groups: HSWY low dosage group,HSWY medium dosage group,HSWY high dosage group and Heshouwan(HSWW) group.The sub-acutely aging model rats were induced by D-galactose,and rats in the prevent aging group were received intragastric administration of HSWY and HSWW with D-galactose intraperioneal injection.The gene expressions of p53,p19~(ARF),Rb and p16 were detected in the ovaries of each group with reverse transcription polymerase chain reaction,and the protein expressions of Rb and p16 in the ovaries with Western blotting.Results The model group rats were in the aging status with low spirits and withered and yellowed hair.The ovaries of the rats in the model group expressed aging change.The gene expressions of p53,p19~(ARF),Rb and p16 were up-regulated and the protein expressions of Rb and p16 were increased in the ovaries of aging rats.HSWY significantly suppressed the gene expressions of p53,p19~(ARF),Rb and p16(P

The development of effective therapy for children with acute lymphoblastic leukemia (ALL) is one of the greatest successes of clinical oncology. However, cure rates for adults with ALL remain relatively low. Adolescents are the special population between children and adults. These patients group will be received protocol from either pediatric or adult oncologists depending on referral pattern. In recent years, researchers from abroad large cooperative groups show pediatric-based protocol has better outcome than adult-based protocol. In this article, the protocol of ALL in children and adults are compared . It seems the first and probably the most important reason is the dose intensity of the nonmyelosuppressive chemotherapeutic agents, especially asparaginase.

Tumor recurrence and drug resistance impact patients'therapeutic effect and prognosis seriously.In recent years,it has been found that epigenetic changes are involved in drug resistance.DNA methylation is one of the ways of epigenetic.DNA methylation of drug metabolism enzyme gene can affect gene's expression,leading to drug resistance.Methotrexate(MTX),a folic acid antagonist,is the most widely used drug in the treatment of malignant tumors,such as leukemia,osteosarcoma,head and neck cancer,and so on.Reduced folate carrier(RFC) is the main transporter cartier of MTX,and gene methylation is related to tumor cells'resistance to MTX.This paper reviews the role of RFC,relation of RFC methylation and methotrexate resistance and the factors of RFC methylation.

Objective: To investigate the expression of histone deacetylase 2 (HDAC2) in esophageal squamous cell carcinoma (ESCC), and to explore the effects of downregulation of HDAC2 expression on cell proliferation, cell cycle and apoptosis of EC9706 cells and their possible molecular mechanisms. Methods: The expression of HDAC2 protein in ESCC tissues was detected by immunohistochemistry. HDAC2 small interfering RNA (siRNA) and control siRNA were transfected into ESCC EC9706 cells, and then the EC9706 cells were randomly divided into three groups, including untreated group, siRNA control group and HDAC2 siRNA group. The expression of HDAC2 protein in EC9706 cells was detected by Western blotting. The cell proliferation status was examined by cell counting Kit-8 (CCK-8) method. The cell cycle and apoptosis were detected by flow cytometry (FCM). The expressions of proteins related to cell proliferation, cell cycle and apoptosis were detected by Western blotting. Results: The positive expression rate of HDAC2 in ESCC tissues (79.71%) was significantly higher than those in normal esophageal mucosa (51.11%) and paracancerous tissues (dysplasia, 23.19%), and there was a significant difference among these three tissues (χ2=44.121, P=0.000). The expression of HDAC2 protein wasnot associated with age and gender of patients with ESCC (both P>0.05), but closely associated withhistological grade, invasive depth, TNM stage and lymph node metastasis (all P<0.05). HDAC2 siRNA effectively down-regulated the expression of HDAC2 protein, obviously inhibited the cell proliferation, arrested cell cycle at G0/G1 phase and induced apoptosis of EC9706 cells. In addition, the result of Western blotting showed that down-regulation of HDAC2 expression could markedly increase the expressions of p21 protein and apoptosis-related bax protein while decrease the expressions of cyclin D1 and bcl-2 proteins. Conclusion: HDAC2 may play an important role in occurrence and development of ESCC. The downregulation of HDAC2 expression-mediated proliferation inhibition, cell cycle arrest and apoptosis of EC9706 cells may be tightly associated with the increased expression levels of p21 and baxas well as the decreased expression levels of cyclin D1 and bcl-2.

OBJECTIVE:To explore the feature and regularity of ADR induced by animal bone polypeptide medicine,so as to provide reference for rational use of these drugs in clinical practice. METHODS:In retrospective analysis,96 cases of ADR oc-curred in our hospital during Jan. 2009-Jun. 2016 were analyzed statistically in terms of patients'gender and age,drugs involved, occurrence time,route of administration,organs and systems involved,association,prognosis,etc. RESULTS:Among 96 cases (including 17 serious ADR),the ratio of male to female was 1.34 : 1,and 56.25% of them were above 40 years old. ADR mainly occurred within 15 minutes after medication(39.58%)dominated by intravenous drip. Organs/systems involved in ADR were main-ly lesion of skin and its appendants(34.81%),followed by respiratory system damage(18.35%)and systemic damage(16.46%). In aspect of ADR association,41 were probable(42.71%)and 55 were possible(57.29%). After suffering from ADR,43 patients (44.79%)were cured after drug withdrawal or corresponding treatment,and 53 patients(55.21%)were recovered. CONCLU-SIONS:Medical staff should master the regularity and characteristics of ADR induced by animal bone polypeptide medicine,while strengthen rational drug use management and monitoring to ensure the safety and effectiveness of clinical drug use.

Objective:To control the maintenance cost of medical equipment and improve the efficiency and service level for maintenance, and to research the management about classification maintenance for medical equipment based on analytic hierarchy process (AHP).Methods: 69 clinical department and 14 engineers were involved in the questionnaire survey and the evaluated factors were obtained from their questionnaires. The (AHP) was used to determine what is the factor weight of maintenance for the medical equipment, and then calculate the maintenance scores of the equipment. Finally, the weight scores were applied to ABC classification method and the equipments will be divided into three types (A\B\C) as this method, and they will be managed by different mode.Results: Depended on the sixth order analysis data from 6 factors of evaluation (price, frequency, stability, running time, standby factor and difficulty of maintenance) that were compared between any two factors by using AHP, through comprehensive scores ratio to got A\B\C classification and work out relative implement countermeasure of maintenance. The new classification management mode has achieved planning and preventive maintenance for key equipment, regular maintenance for major equipment, and maintenance after event for general equipment. After the method was applied, the fault rate of second half of 2016 year was decrease 30% compared with same time of 2015 year. The total cost of maintenance of 2016 year decreased 10% compared with that of 2015 year. And the satisfaction of clinical department for department of equipment was enhanced.Conclusion: The AHP is applied to classified manage medical equipment and maintain them as weight of factor. This method has resolved many problems on maintenance of equipment, such as confused primary and secondary, and formalism and so on. According to the factor weight of maintenance to manage medical equipment at classification mode, hospital can catch key point of maintenance of equipment, and the maintenance cost can be efficiently controlled, and the work efficiency and clinical service level of equipment department can be improved and enhanced.
