During 2 months from December 1979 to January 1980, Medical practitioners in chonnam province were grouped into Si (city), Eup(town) and Myun (rural area) groups according to the locations of their clinic. 40 practitioners were randomly selected in each group and were asked their opinions about rural medical care in general. Total of 88 practitioners replied to the question as 73.3 percent of response rate in average. The most frequently mentioned advantages of rural practice were ease of clinic opening in Si-and Myun-group respondents and good social relationship in Eup-group respondents. The most frequently mentioned disadvantages were medical isolation in Si-group respondents and resident's ignorance in medicine in Eup-and Myun-group respondents. In all groups, most respondents though that rural medicine care should be delivered by and controled by physician. Suggestions made by Eup-and Myun-group respondents for improving rural medical care by structural change focused on the regional medical insurance system, while Si-group respondents noted district hospital or hospital linkage as most preferable system.

Objective To evaluate the promote effect of Danisco products Bifidobacterium Lactis Bi07 & Lactobacillus acidophilus NCFM on physical intestinal canal microbial eco-system.Methods A 3-week randomized trial was conducted in 400 healthy persons aged from 25 to 45 years,with a male to female ratio of 1∶1,they were randomly divided into 2 groups: placebo group and probiotics group.Each group takes the corresponding products 100 g twice everyday at 10 a.m.and 4 p.m respectively.Results Digestive system on microbial eco-system was effectively improved.The viable count of Bifidobacteria and Lactobacillus was significantly increased.The viable count of Clostridiumperfringen was significantly decreased.Conclusions Significant effectiveness on physical intestinal canal microbial ecosystem were proved by intake Danisco probiotics products 200 g per day for 21 days.

TXB_2 and 6-keto-PGF_(1?) levels of arterial and venous plasma in Wistar and4 Hilltep rats were measured to investigate the roles of TXA_2 and PGI_2 in the hypoxic pulmonary vasoconstriction(HPV) and responsiveness difference of pulmonary vessels to hypoxia between different strains of rats. The results showed that PGI_2 might play an important role in maintaining the low resistance of pulmonary circulation in these two strains of rats. TXA, increased during hypoxia might partially mediate HPV in Hilltop rats, on the contrary, PGI_2 augmented during hypoxia might modulate HPV in Wistar rats. This might be the major methanism responsible for the more intensive responsiveness of pulmonary vessels to hypoxia in Hilltop than in Wistar rats.

Objective To determine the prevalence of sleep disorders and related symptoms of 1 0 years old children in Baoshan Dachang area of Shanghai.Methods From September 201 4 to June 201 5,1 01 6 children at the age of ten were randomly selected and information was collected by using a parent -completed questionnaire to ascer-tain in sleep disorders and related symptoms.Results The prevalence of sleep disturbances in 1 01 6 childrens was 53.5 %,included active 1 6.9%,inattention 1 3.0%,allergic rhinitis 1 2.8%,poor academic performance 1 2.4%, poor learn ablity 1 2.4%,too much sweat at night 8.7%,irritable and slapstick 8.5%,muoth breathing 6.7%,repeat respiratory infection 5.5%,tired easily in the day 5.3%,tousillar hypertrophy 4.7%,growth retardation 3.9%, aweeks at night and sleep terrors 3.4%,anorexia 3.4%,night sleep snoring 2.8%,nasosinusitis 2.6%,bronchial asthma 1 .6%.326 boys in the 502 sleep disorder related symptoms,accounted for 64.9%,21 8 girls in the 51 4 sleep disorder related symptoms,accounted for 42.4%.It was under high prevalence of sleep disorders in male and female children(χ2 =51 .81 5,P <0.01 ).According to BMI,these children were divided into four groups.To compare the incidence of sleep disturbance associated symptoms in children with different BMI.Lean group of children in apnea, aweeks at night and sleep terrors,growth retardation of the occurrence rate was higher,compared to all other groups among children with significant difference.Conclusion At present,it is under high prevalence of sleep disorders and related symptoms at the age 1 0 children in Baoshan Dachang area of Shanghai,which the doctors in Department of ENT and related departments and parents should pay high attention.To develop a good sleep habit of children can help to reduce the occurrence of sleep disorders.

18 F-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) and bone marrow biopsy (BMB) have high consistency in the detection of lymphoma bone marrow infiltration (BMI).18F-FDG PET/CT has a high sensitivity to Hodgkin lymphoma (HL) and aggressive non-Hodgkin lymphoma (NHL) BMI,while the sensitivity of indolent NHL is low.Since 18F-FDG PET/CT may appears false positive or false negative,so it can not replace the conventional BMB.We can carry out a BMB under the guidance of 18F-FDG PET/CT,which can greatly improve the detection rate of BMI.

With the increasing incidences of pancreatic diseases and the rapid development in techniques of magnetic resonance imaging (MRI) lately, superiorities of MRI are obvious. This article reviewed MRI depictions of pancreatic diseases, their values in diagnosis and differential diagnosis, and clinical application of MRI in this field.

Long non-coding RNA(lncRNA) is a group of functional RNA molecules, which is more than 200 nucleotides in length and lacks ability of encoding protein. The current study indicates that the abnormal expression of lncRNA is closely related with breast cancer progression. Some lncRNA takes part in regulating the process of breast cancer invasion and metastasis. This article reviews the abnormal expression of lncRNA in breast cancer and the relevance with breast cancer invasion and metastasis, which is expected to provide new strategy for breast cancer diagnosis and treatment.

目的观察75岁以上老年人急性心肌梗死(acute myocardial infarction,AMI)静脉溶栓治疗的疗效。方法48例75岁以上采用尿激酶溶栓治疗的患者与同期94例<75岁的AMI患者溶栓治疗做对照。结果≥75岁组的再通率为68.7%,<75岁组为72.3%;轻度出血分别为6.3%和5.3%,重度出血均为0%;心率失常分别为41.6%和49.9%;病死率为6.3%和5.3%。两组患者12h静脉溶栓治疗再通率无显著性差异,并发症及病死率也无显著性差异(P>0.05)。结论75岁以上老人静脉溶栓治疗是安全有效的。
