Objective To investigate Zunyi C Class infectious diseases ,and provide basis for formulating prevention and control measures .Methods A network report of class C infectious diseasesfrom in Zunyi city from 2009 to 2012 was statistically analyzed by Excel software ,and data analysis was conducted by descriptive epidemiological method for .Results In Zunyi city from 2009 to 2013 reported a total of 8 kinds of class C infectious diseases (68 915 cases) ,annual report incidence rate was 213 .23/10 million;the top three are hand foot and mouth disease ,mumps and other infectious diarrhea ,accounted for 62 .22% of the total reported ca‐ses ,19 .68% and 13 .44% .There was slightly higher incidence rate of the disease from March to August and the main risks were in scattered children ,kindergarten children and students ;the age of onset lie in the population under 14 years old ,the male to female ratio was 1 .67∶1 .00 (χ2 =3 445 .64 ,P<0 .01) .Conclusion Hand foot and mouth disease ,mumps ,other infectious diarrhea and other infectious disease has become an important public health problem in Zunyi city .Therefore ,the kindergarten ,school infectious disease epidemic monitoring should be strengthened ,the infectious disease outbreaks should be reduced ,and communicable disease diagnosis and reporting standards ,which is helpful to improve the epidemic situation of infectious diseases research and prevention and control level should be improved to maintain the protection of public health .

Objective To summarize the image features of nutcracker syndrome (NCS)on 320 multi-slice spiral computed tomo-graphy angiography (CTA).Methods The clinical and CTA data of 1 5 cases with NCS were analyzed retrospectively.The angle(α) between superior mesenteric artery (SMA)and abdominal aorta(AA)was measured.The ratio(a/b)of the diameters of the most narrow and the most wide at the hilus of left renal vein (LRV)was calculated.Results The angel(α)of 1 5 cases were ranged from 15.5°to 27.6°.The range of a/b was from 0.22 to 0.35.Left renal enlargement were observed on four cases.Collateral circulation were detected on two cases.Duodenal stasis was detected on one case.Conclusion CTA findings of NCS is characteristic,which can noninvasively,rapidly and comprehensively display the surrounding anatomy of LRV.It is helpful in clinical diagnosis.

OBJECTIVE： To evaluate the literature quality of systematic reviews/Meta-analysis of oral administration of traditional Chinese medicine （TCM） in the treatment of lumbar disc herniation （LDH） using radar plot， and to provide scientific and effective evidence for clinical use of medicine. METHODS： Retrieving CNKI， VIP， Wanfang database， CBM， PubMed， Cochrane library and Embase during the establishement of database to Oct. 1st， 2018， the literatures about systematic reviews/Meta-analysis of oral administration of TCM in the treatment of LDH were collected. After data extraction of literatures met inclusion criteria， the quality literatures were evaluated from 6 aspects of radar plot （year of publication， design type， AMSTAR methodological quality evaluation， PRISMA reprot quality evaluation， homogeneous， publication bias risk）. The average score of rank number was calculated. Moreover， Excel 2010， Adobe Illustrator CC and other software were used to draw and optimize the radar plot. RESULTS： A total of 6 qualified literatures were included； average score of rank number of 6 aspects were 3.83， 4.67， 3.83， 3.67， 6.00， 4.67， scoring 4.56 in average. Multivariate evaluation of radar plot showed that 2 studies had higher qualities and only 1 study had lower qualities relatively. However， problems could be found such as information selection bias， inclusion and exclusion criteria， publication situation， limitations， project registration. CONCLUSIONS： The literature quality of systematic review/Meta-analysis of oral administration of TCM in the treatment of LDH need to be improved， starting with strengthening methodological quality and reporting quality. Radar plot is a visual and effective method of graphic evaluation， which is worth popularizing and applying in the future.
