This paper analyzes the document contents of targeted admission medical students in 16 provinces of China in 2016.Through analyses of the characteristics of the program, this study found that, 1) the number of admissions is determined by the national level and issued to the provincial level, where rural students are the main source of students, undergraduate program is the main enrollment category, and clinical medicine and traditional Chinese medicine are the main majors of admission;2) the number of admissions and the actual demand of health professionals of primary health care institutions do not match, the incubation period is too long, there is a shortage of targeted training model, contract signing is difficult to implement, and other problems.Therefore, in accordance with the problems, this paper suggests that, 1) the government should increase the number of admissions to match with the demands;2) a three-year bachelor's degree should be set up in order to shorten the incubation period;3) the training model of targeted admission medical students should be changed;and 4) various powerful measures should be carried out to attract and keep excellent health care professionals.

Objective To identify the occurrence and microorganism profile of device-associated healthcare-associa-ted infections (DA-HAIs)in the intensive care unit (ICU)of a university hospital in China.Methods From Janua-ry 1 to November 30,2015,patients admitted to the ICU of a university hospital in China for more than 48 hours were performed prospective descriptive study. DA-HAIs were defined according to the criteria of the Centers for Disease Control and Prevention (CDC)of U.S.,descriptive statistical analysis was performed.Results Of 254 pa-tients admitted to ICU,the overall incidence of DA-HAIs was 15.35% ,with 10.23 cases of DA-HAIs per 1 000 ICU-days;the incidence of ventilator-associated pneumonia (VAP ),catheter-associated urinary tract infection (CAUTI),and central line-associated bloodstream infection (CLABSI)were 7.05 per 1 000 ventilator-days,4.91 per 1 000 urinary catheter-days,and 3.22 per 1 000 central line-days,respectively. The main infection site was lower respiratory tract,accounting for 48. 27% ,followed by bloodstream system (27. 59% ),urinary tract (22.99% ),and gastrointestinal tract(1.15% ). The major isolated microorganism was Acinetobacterbaumannii (21 .52% ).Conclusion The surveillance system can identify the epidemiological status of DA-HAIs and make effec-tive control measures to ensure the healthcare safety.

Cancer is one of the main diseases that threaten the health of human.In order to increase the cure rate of cancer,the accurate therapy of cancer must be developed speedily.The most effective method for curing cancer is intensity modulated radiation therapy(IMRT),which can increase the local control rate of cancer and decrease complications of tissues.IMRT is considered to be an important breakthrough in cancer therapy.The dose produced by it is better than 3D-CRT and can achieves better results of therapy,which has been confirmed in the clinical therapies of head cancer,neck cancer,prostate cancer,breast cancer,cervical cancer and pancreas cancer etc.The developing course of IMRT,the methods of intensity modulation,the enforcement process of IMRT and the feasibility test of therapy plans are emphatically introduced.

With the developmetn of the medical humanistic education,more and more problems appear.The casualness of the medical humanistic curriculum,the monotony of the method of the evaluation,the insufficiency of the content,the inadequacy of the quality of the teachers,and the poor effect of the education are the factors affecting the development of our medical humanistic education.Through comparison of the humanistic education home and abroad,we find the key to these problems are the innovation of the curriculum and evaluation.

Possessing ideological qualities is a gradual process. We should establish a multiplex, synthetical and entire assessment system for the ideological and political theory course exams in medical colleges. The innovation of exam mode can promote the diversification of teaching style.

Based on the anatomical study of kidney in mammals of 27 families and 163 species, the authors discovered Anoa depressicornis type kidney, and obtained the evidence of morphological transition between Ox-type kidney and Pig-type kidney. After observing the renal papillary structure of Budorcas taxicolor, the evidence of fact and theoretical bases of the biological view was proved that the general papillae are developed from the multi-papillae kidney. The author advanced a new type of leaf-shaped multipapillae kidney. The authors suggest to classify the mammalian kidneys principally into 2 groups, i. e, simple and composite kidney, and subdivide them into 4 types, i. e, multipapillae and concentrated papillae for simple kidney and leaf-shaped multipapillae and ball-shaped mono-papillae for composite kidney. In contrast to the previous classification, the 2-group 4-type classification recommended here with its solid anatomical foundation is conformable with the viewpoint of biology, and is more practical and integrated.

BACKGROUND:It is discovered recently that miRNA is a new regulator that is able to have an impact on gene expression and miRNA contributes to proliferation, differentiation and self-renewal of pluripotent stem cels.
OBJECTIVE:To investigate the mechanism by which miR-155 regulates chondrogenic differentiation of bone marrow mesenchymal stem cels.
METHODS: Sixty healthy Sprague-Dawley aged 12 weeks were randomized into study group and control group, with 30 in each group. Under anesthesia, rats were sacrificed to harvest bone marrow of the lower limbs. Then bone marrow mesenchymal stem cels were isolated, cultured, and transfected with miR-155 mimics in the study group and a negative control sequence in the control group. After chondrogenic induction, RT-PCR was used to detect the expressions of Sox9, Colagen II, Aggrecan and Colagen X gene, and western blot assay to detect the expression of Sox9 and Runx2 proteins.
RESULTS AND CONCLUSION:Compared with the control group, the mRNA expressions of Sox9, Colagen II and Aggrecan were higher, but the mRNA expression of Colagen X was lower in the study group (P < 0.05); the protein expression of Sox9 was higher, but the protein expression of Runx2 was lower in the study group (P < 0.05). These findings indicate that miR-155 promotes the chondrogenic differentiation of bone marrow mesenchymal stem cels and moreover, it can suppress the hypertrophy trend of bone marrow mesenchymal stem cels differentiating into chondrocytes.

Objective To observe the factors affecting inadequate ST-segment resolution in patients with acute ST-segment elevation myocardial infarction after emergency percutaneous coronary intervention (PCI). Methods The patients with acute ST-segment elevation myocardial infarction undergoing emergency PCI were enrolled for study. According to the ratio of ST-segment resolution, 186 cases were divided into inadequate ST-segment resolution group (54 cases) and relatively adequate ST-segment resolution (132 cases). Clinical data of two groups were compared. The single factor and multiple Logistic regression analysis were performed to determine the factors influencing inadequate ST-segment resolution. Results Pre-infarction angina was protective factor of inadequate ST-segment resolution after emergency PCI (OR=0.361, 95%CI 0.131-0.994, P<0.05). Anterior myocardial infarction, attack-to-balloon time, Killip classification and white blood cell counts were risk factors of inadequate ST-segment resolution (OR=2.389, 95%CI 1.194-4.781;OR=1.655, 95% CI 1.082-2.532; OR=1.319, 95% CI 1.026-1.695; OR=1.184, 95% CI 1.004-1.396, P<0.05). Conclusions Patients with pre-infarction angina could reduce the risk of inadequate ST-segment resolution after PCI. Patients with anterior myocardial infarction,long attack-to-balloon time, Killip classification≥2 and high blood cell counts could increase the risk of inadequate ST-segment resolution, and earlier and more active clinical intervention should be taken.
