With rapid developmerit of technology of three dimensional conformal radiotherapy(3DCRT)and intensity-modulated radiotherapy(IMRT),the immobilization and repetition of patients'treatment position need is more accurate.The setup errors of thoracic cancer patients are great because of the breathing motion of lungs.The method of utilizing CBCT(cone beam computered tomography)to verify and correct setup errors is convenient and effective.CBCT,as one way of imaging guided radiation therapy(IGRT),is directly fixed on linear accelerator,has an important role and broad application prospects in reduction of setup error.

Important developments have been obtained in research for gastric carcinoma with maturity of proteomics technology.The proteomics technology has been used to determine gastric carcinoma specimens such as cell lines,tumor tissues,serum,gastric juice,etc.Achievements have been gained in finding tumor marker and investigating biological behavior of gastric carcinoma as well as other aspects.

This paper analyzes deficiencies of our journal in contribution source, quality of articles, correlative policy, editing system, journal feature, distribution, etc. Starting from the present conditions, it offers special suggestions on thesis quality control, conversion of the journal to a bimonthly, establishment of scientific editing system and the ways to make the journal prominent with its own feature, and to improve its overall academic standard by a series of measures.

In recent years many basic-level hospitals formed teaching cooperation relationshipwith the medical universities and colleges. And more and more basic-level hospitals successfully become affiliated hospitals indirectly under medical colleges. Some medical universities and colleges make bold attempt to put foreign students in the affiliated hospitals indirectly under medical colleges. This essay analyzes the problems and deficiencies of foreign students' practice in such hospitals in combination with receiving foreign students practice experience, puts forward concrete proposals to solve the problem and gives some suggestions.

Objective To observe the effect of edaravone on haemorheology in the patients with cerebral infarction. Methods 96 patients with cerebral infarction were collected and randomly divided into observation group and control group. 48 patients were divided into each group. Conventional thrombolysis therapy was used in control group,and salvia miltiorrhiza intervenous drop infusion after thrombolysis. Edaravone intervenous drop infusion after thrombolysis was used in observation group. The curative effect,neurologic impairment score,and the haemorheology index(the whole reduced viscosity,hematocrit, ESR and fibrinogen) were detected in all patients. Results All the patients got a good curative effect, the improved neurologic impairment score and the haemorheology index after different treatment. The curative effect,the neurologic impairment score and the haemorheology index were better in observation group after treatment than that in control group (all P＜0. 05). Conclusion Edaravone could play'a better therapeutical effect in patients with cerebral infarction by cleaning the free radical and improving the state of haemorheology.

Diabetes and cancer, two heterogeneous multffactorial severe chronic diseases, are closely related. Epidemiological studies clearly indicate that diabetics have an increased risk and mortality of several cancers, including cancers of the pancreas, liver, breast, colorectum and urinary tract. Insulin is a growth factor with preeminent metabolic and mitogenic effects and functions at both receptor and post-receptor level during cancer development. As a result, hyperinsulinemia is the most likely cause of cancers among diabetic patients. However, anti-diabetic drugs, obesity, hyperglycemia, and increased oxidative stress may also contribute to the increased cancer risk among diabetics.

Cerebral palsy(CP)is one of the main diseases which induce the invalids of children nervous system.The pathogenesis of CP iS fairly complex,which correlates with many factors.At present,there is no one kind of animal odel of CP that can be received by the public.To solve this problem,this review summarizes the most up-to-date three models which relate to the pathogenesis,ischemia and hypoxia model,infection model and hyperbilirubin model,and compares their different validities,eventually brings forward the common effective criterions to identiticare different models.Among these three models,the ischemia and hypoxia model is the most popular application and research objection,the two others are sprouting on their way waiting further develpoment.

Objective To evaluate the clinical effect and safety of gemcitabine plus carboplatin regimen in the treatment of advanced non-small cell lung cancer(NSCLC) in aged patients. Methods 110 cases of aged patients with NSCLC , were divided into GEM group and NVB group according to the patients "options. GEM group received 1 000 mg/m2, GEM at day 1 and 8, and AUC 5 CBP at day 1. NVB group underwent the therapy of 2.5 mg/m2, NVB at day 1 and8,and 80 mg/m2 DDP at day 1 and 3. Both were treated with 21 days as a cycle. Results Overall re-sponse rate was 75.0% in GEM group and 72.0% in NVB group without significant difference( P>0.05). The medi-an survival time(MST) ,disease median response time(DPT) and one year survival rate were similar in two groups( P>0.05). The incidence of adverse reactions was significantly lower in GEM group than in NVB group ( P<0.05 ).Conclusion Gemcitabine plus carboplatin regimen is effective and safe in treatment of advanced non-small cell lung cancer in aged patients

Many voting activities such asThe Best Medical Workers put medical workers onto moral high ground,while medical dispute,medical anomie and other news pushed them to the abyss of criticism.These are all involved in the pan-moralization of medicine-related consensus of mass media.Taking specific opinion as example,this paper listed the pan-moralization characteristics including judging the complicated problems with ethical standard merely,evaluating behaviors of physicians and patients with idealistic principles,determining the whole moral outlook from the individuals,analyzed the reason of social emotional outbursts,traditional moral interference,media ethics anomie,and lack of public rationality,and finally proposes the strategies to avoid pan-moralization of medicine-related consensus from the micro and macro level.
