Objective:To reflect the training of basic-level medical stuff by investigating the doctor-patient cognition status of patients in a county-level hospital.Methods:The questionnaire of 180 patients collected from a county hospital in Shaanxi province was analyzed by Rank sum test and Descriptive analysis with SPSS17.0.ReSults:There were no statistically significant differences in the evaluation of current doctor-patient relationship from patients of different ages,occupations and degrees of education (P ＞ 0.05).82.2％ of the patients believed that the doctor-patient relationship is harmonious or somewhat harmonious.Moreover although the patient's trust in doctors is not high,there is a certain sense of recognition;and they put forward some expectation and requirements on doctor's professional skills,communication skills and professionalism.Conclusion:Considering the patients' feedback,local medical colleges and universities should reflect medical education ideas,play an active synergy model in the training of students' professional skills.In the meantime,they should strengthen the medical internship management,while paying equal attention to enhance students' responsibility and professionalism to serve the grassroots.

Applying the principle of Evidence-Based Medicine to the clinical teaching,we have made the students raise the cognition level on the diagnose of diseases and treating policy and trained their clinical logic thinking ability.

Clinical thoughts based on symptoms, physical signs and examine outcomes is a process of analysis, judgement and conclusion of disease diagnosis. To cultivate an exact thinking model can avoid taking a part for the whole or a miss in disease analysis, so to cultivate clinical thoughts in clinical practice can elevate medical students'clinical skills.

Objective] To observe the clinical efficacy and 5-HT of Shugan Jianpi Tiaoshen acupuncture treatment for senile patients with constipation type of irritable bowel syndrome(IBS-C). [Method] A total of 68 patients with IBS-C were allocated into control group and acupuncture group from June 2015 to June 2014. 34 patients in the control group, who accepted Lactulose oral solution and Citrate Mosapride Citrate, of in 15 males and 19 females, the mean age was 66.8, the average duration of disease was 15.6 months;34 patients in acupuncture group, who accepted acupuncture treatment based on control group, in 17 males and 17 females, the mean age was 65.9, the average duration of disease was 17.1 months. Acupoint selection:Tianshu, Zusanli, Taichong, Xingjian, Qimen, Baihui, Neiguan. Observe constipation symptoms, depressive symptoms, and quality of life and serum 5-HT levels before and after treatment. [Result] The pre-treatment constipation symptoms and depressive symptom scores in two groups were decreased than post-treatment( P<0.05), which showed two methods can improve constipation and depressive symptoms of IBS-C patients. After treatment, constipation symptoms and depressive symptoms score in acupuncture group were lower than that in control group(P<0.05), which showed the effect of acupuncture was better. The eight dimensions of SF-36 were higher than those before treatment in total patients(P<0.05), which showed two methods can improve quality of life of patients; differences of physiological function, physiological function between acupuncture group and control group had no statistical significance( P>0.05), but body pain, vitality, emotional function, mental health, social function, and general health values were higher than that of the control group( P<0.05), which showed acupuncture treatment can reduce physical discomfort and improve the quality of life of patients. After treatment,serum 5-HT in control group was 33.8 pg/ml, in acupuncture group was 27.6 pg/m, which were lower than pre-treatment. 5-HT in acupuncture group was lower than control group( P<0.05), which showed the effect of acupuncture on regulation of 5-HT was more significant. [Conclusion]Shugan Jianpi Tiaoshen acupuncture can modulate 5-HT level of elderly patients with IBS-C, and play its role in modulating gastrointestinal function, improving constipation symptoms, depressive symptoms and quality of life.It is an effective method for the treatment of elderly patients with IBS-C.

Objective To observe and explore the value of combined detection of serum BNP and TnI in patients with acute heart failure(AHF). Methods 60 AHF patients from February 2015 to April 2016 were selected as observation group, and divided into Level III group(n=32) and Level IV group(n=28) according to NYHA classification;60 healthy patients at the same period were selected as control group.BNP and TnI levels were detected by chemiluminescence in each group, and were compared.Results BNP and TnI of observation group were(2624.4 ±378.6) ng/mL and(0.87 ± 0.22) ng/mL, while in control group were(72.4 ±20.2) ng/mL and(0.13 ±0.02) ng/mL, the differences were significant(P<0.05);BNP and TnI in level III group before treatment were significantly lower than grade IV group(P<0.05), after treatment, the level of BNP and III in group IV and group TnI were significantly lower(P<0.05), and the levels of BNP and TnI were significantly lower than those in III group after treatment(P<0.05). Conclusion BNP combine with TnI levels monitoring play an important role in AHF diagnosis and prognosis evaluation, can help to guide the treatment of AHF.

Objective　To investigate the changes and its clinical significance of plasma neuropeptide Y(NPY) concentration in patients with pregnancy induced hypertension (PIH). Methods　Plasma NPY levels were detected by radioimmunoassay in 30 patients with PIH, 20 normal non-pregnant women and 23 normal pregnant women. The PIH group was subdivided into mild, moderate and Severe subgroups, and the NPY concentration was also measured in these subgroups respectively at admission and one week after delivery. Results　The plasma NPY levels in patients with PIH ［(164.16±68.32) ng/L］ were significantly higher than those of normal non-pregnant women and normal pregnancies ［(86.60±20.65) ng/L, (82.42±12.46) ng/L, P<0.01, respectively］. There was significant difference among plasma NPY levels among the patients with mild, moderate, and severe PIH at admission (P<0,01). At one week after delivery the concentrations of plasma NPY were significantly decreased in the moderate and severe subgroups compared with the value measured at admission (P<0.01). Moreover, the NPY levels in patients with severe PIH after delivery were still higher than those of normal non-pregnant women. Conclusions　The results suggested that the level of NPY in plasma is increased in women with PIH. Elevated plasma NPY levels may play a key role in the development of PIH.

BACKGROUND:Extracel ular vesicles (EVs) are a kind of subcel ular component produced by paracine mechanism including exosomes, microparticles and microvesicles, which have become hotspots in recent years. OBJECTIVE:To review the research status and progress of EVs, especial y in the studies about definition, secreting mechanism, isolation and identification, biological characteristics and functions in diseases as wel as in biomedical research. METHODS:The first author retrieved PubMed and CNKI databases for relative articles published from July 2006 to August 2016. The keywords were“extracel ular vesicles, exosome, microvesicle, microparticle”in English and Chinese, respectively.RESULTS AND CONCLUSION:A total of 44 eligible literatures are enrol ed. Almost al cel s can secrete EVs, which contain a variety of metrocyte-derived bioactive molecules, such as lipids, proteins, mRNAs, microRNA, lncRNA, cicrRNA, and non-coding RNA. These bioactive molecules are encapsulated in EVs or binding with the membrane. EVs are described to be involved in inflammation, immunity, signal transduction, cel survival and apoptosis, angiogenesis, thrombogenesis, and autophagy, which are of great significance to the maintenance of homeostasis and disease progression. Special EVs may be used as new biomarkers for the diagnosis and prognosis of many diseases and serve as novel tools in the fields of antitumor therapy, regenerative medicine, immunoregulation and vaccination and drug delivery. But the molecular mechanisms regulating the secretion of EVs and the specific pathways activated upon EVs interaction with the target cel are not ful y understood. Based on miRNA, lncRNA and circRNA are attracting researchers’ attention.
