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.

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.

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.

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 observe the security, major cardiac adverse events and target lesion revascularization (TLR) in patients underwent Sirolimus Eluting Stents and Paclitaxel Eluting Stents implantation. Methods A total of 224 consecutive patients from Dec, 2002 to Dec, 2004 who randomized to receive SES and PES implantation were enrolled with 168 male cases and 56 female cases. The average age was 60.9?11.1 years (35-86 yrs) and the median follow-up period was 13.4?6.7 months (3-27 ms). Results There was no difference in baseline characteristics between both groups. No acute and subacute thrombosis events occurred in both groups but two delayed thrombosis occurred in the PES group. There were six MACEs in the PES group, and among them two patients occurred delayed thrombosis and four patients underwent target lesion revascularization. There was one patient underwent TLR in the SES group. Conclusion Both drug eluting stents reduced MACEs and TLR, but the rate of delayed thrombosis, MACEs and TLR was lower in the SES group than in the PES group.

Objective:To investigate the training of writing research paper for graduate students majoring in medical imaging, therefore improving international academic communication. Methods: Analyzing the problems existed in English paper writing for the graduate students majoring in medical imaging. According to the feature of English paper writing in the field of medical imaging, the new teaching model was used and the problem-based-learning method was introduced.Results: The new training model of English research paper writing is practical and helpful for graduate students majoring in medical imaging to improve their writing skill and research ability.Conclusion: The training of English research paper writing is efficient for graduate students majoring in medical imaging. The training process can lay good foundation for their future research careers.

Objective To study the value of contact heat evoked potentials (CHEPs) for the early diagnosis of diabetic peripheral polyneuropathy. Methods Seventy-five diabetic patients were examined by conventional nerve conduction velocity studies and then divided into 2 groups: diabetics with normal nerve conduction and diabetics with abnormal nerve conduction. Thirty-three normal subjects were used as controls. Toronto Clinical Neuropathy Sco-ring System was used to evaluate the patients. CHEPs were recorded using different stimulation intensities at different temperatures. Results The peak latencies of 45℃ , 50℃, 53℃ in diabetics with normal nerve conduction group were longer than those in normal control group, with a significant difference between the 2 groups(P<0.05). The peak latencies of diabetics were positively related to Toronto scores. Conclusion CHEPs could detect the impair-ment of diabetic peripheral nerve and reveal the impairment earlier than conventional nerve conduction velocity exami-nation, The prolongation of peak latency in diabetics group was significantly and positively related to clinical condi-tion.
