Talented persons and medical equipment are both important for the development of the hospital. Improved management of medical equipment maintenance can make the equipment effective and lower maintenance cost, in which regular maintenance, enhanced management of equipment files are involved in.

BACKGROUND: In vivo animal experiments have found that magnesium al oy stents can be completely degraded in a slow, orderly and non-toxic manner fol owing the vascular remodeling. OBJECTIVE: To investigate the applied effect and biocompatibility of a new type of magnesium al oy stent in blood vessels. METHODS: Forty-two crossbreed dogs were implanted with absorbable magnesium al oy stents via the coronary artery or left femoral artery. At days 1, 3, 5 and weeks 1, 2, 3, 4 after implantation, coronary or femoral artery angiography, inflammatory factor detection and morphological analysis targeting intimal hyperplasia were performed. RESULTS AND CONCLUSION: At 1 day after implantation, the stents had the complete shape and were ful y extended; at 3 days after implantation, the stents were degraded partial y; at 1 week after implantation, the stents were degraded completely. Within 1-3 weeks after implantation, the levels of tumor necrosis factor α, interleukin-6 and interleukin-8 continued to decrease. At 2 and 3 weeks after implantation, the target vessels presented with mild intimal hyperplasia. As time went on, the hyperplasia area increased gradual y, and the percentage of intimal hyperplasia increased gradual y. Blood magnesium concentration remained unchanged before and after stent implantation. The results show that the new absorbable magnesium al oy stent can be completely degraded within 1 week after stent implantation and has good biocompatibility.

Lung cancer is the most common cause of cancer death worldwide.To separate and identify the proteins expression in tissue or serum in lung cancer patients which have significance meanings in nosogenesis, early diagnosis, metastasis and treatment. Hepatocyte growth factor is a muhifunctional factor,and with a number of biological activities in tumor. In this review, we summarize the effects and perspectives of hepatocyte growth factor and its receptor c-Met in lung cancer.

Objective To explore the value of MRI sequence and MRA for diagnosis of moyamoya disease(MMD).Methods Retrospective analysed of 1 8 cases of moyamoya disease clinical datas,1 8 cases were used routine head MRI scan,including T1 WI, T2WI,DWI,transverse and sagittal T2WI sequence FLAIR;MRA three dimensional time of flight(3D-TOF).Results 18 cases of patients with MRA showed bilateral internal carotid artery,anterior cerebral artery distal and proximal middle cerebral artery steno-sis or occlusion of signs.Among them,1 1 cases were found with secondary cerebral infarction,3 cases of cerebral hemorrhage,7 ca-ses of centrum semiovale,corona radiata and periventricular cerebral ischemia,4 cases of cerebral atrophy,8 cases of cerebral soften-ing and gliosis.Conclusion MRI and MRA examination have important value in the diagnosis of moyamoya disease,treatment.

The literatures on methods of pharmacodynamic of Chinese medicine in treating brain injury in vitro nearly 10 years were collected and summarized. The studies found that evaluated methods of pharmacodynamic of Chinese medicine in treating brain injury in vitro as followed: the experimental methods of anti-brain injury medicine were mainly used in vitro by serum or cerebrospinal fluid pharmacology, the cell models ofβ-amyloid toxicity, low sugar hypoxia, MPP+ toxicity were often used, the indexes of evaluation such as pathology, neuronal apoptosis, brain energy metabolism and oxidative stress of neuronal cells were chosen. When the researchers evaluate the pharmacodynamic of Chinese medicine, the appropriate experimental models and indexes will be selected based on experimental purposes.

OBJECTIVE:To investigate the feasibility of defined individual treatment course as evaluation index of rational use of drugs.METHODS:The doses of antibiotics and treatment course in 63 patients with type Ⅰ incision operation of our hospital in Jan.2010 were taken as examples.Case analysis,DUI evaluation and defined individual treatment course evaluation were adopted.Similar results were obtained by 3 kinds of methods.RESULTS&CONCLUSION:Results of 3 kinds of methods are consistent.DUI evaluation isn't closely associated with treatment course.Defined individual treatment course is more sensitive and available than DUI based on the introduction of dose and treatment course.

Objective To compare the different operation routes of laparoscopic right hemicolectomy (up‐to‐down vs.medial‐to‐lateral dissection sequences ).Methods In total ,56 cases enrolled in the Central Hospital of Wuhan between Janu‐ary 2013 and January 2014 were randomly divided into the up‐to‐down group and medial‐to‐lateral group.Statistical data in terms of general information ,operation time ,blood loss ,rate of conversion to open surgery ,number of lymph nodes harvested , postoperative complications ,time to first bowel movement and hospital stay time were compared and analyzed.Results The up‐to‐down group has the advantages of shorter operation time [(128.24 ± 21.14) min vs.(166.45 ± 30.23) min ,P<0.01] ,lower conversion rate(0% vs.7.14% ,P=0.035)and less blood loss= [(45.67 ± 10.66) mL vs.(78.45 ± 40.28) mL ,P<0.01] than the medial‐to‐lateral group.However ,there were no significant differences in terms of general information ,number of lymph nodes harvested ,rate of postoperative complications ,time to first bowel movement and hospital stay time (all P>0.05) .Conclu‐sion Taking the superiority of broad perspective ,clear image ,safety and less blood loss into consideration ,the up‐to‐down op‐eration route of laparoscopic right hemicolectomy deserves clinical recommendation.

Tissue engineering is a kind of cross subject,which develops on the basis of cell biology,molecular biology,bio-material science and clinical medicine.The aim of tissue engineering is to restore and improve the function of scathing tissue using bio-substituent.The basis of tissue engineering is to study and develop the frame materials of bio-substituent.Besides the physical and chemical properties satisfying the growth and reproduction of the seed cell,the materials should hold the following properties,including tissue compatibility,bio-degradability,degradable modulability,nontoxicity,easy to mold.The materials studied extensively are PLA and PGA.The polylacticacids frame materials have been used to be the frame materials of bone,cartilage gristle,blood vessel,nerve and skin.The preparation of polylacticacids and its improvement are reviewed in this article.The application development to tissue engineering is also presented.
