OBJECTIVE:To discuss the health risk links involved in self-medication of Chinese urban residents. METHODS: Based on literature study and the experts consultation, the high risk links of the self-medication were defined according to the process of self-medication behavior and the probability of the health harm involved in the self-medication behavior, and the intervention suggestions were put forward for the health risks. RESULTS & CONCLUSIONS: The health risk links involved in self-medication of Chinese urban residents appear as 6 links include self-diagnostic error, incorrect drug choice, failing to understand or follow drug package inserts in taking drugs, irrational drug use, unaware of the drug contraindication, disregarding the physiological particularity of the special drug users. Carrying out education on self-mediation and behavior management among the residents, and reinforcing the government control are the effective ways to reduce the health risk of self-medication.

OBJECTIVE:To explore consumers’perceptions for pharmaceutical care by community pharmacist when purchas-ing OTC drugs. METHODS:Semi-structured interview was conducted for 100 consumers who were recruited in Xingqing District, Jinfeng District and Xixia District of Yinchuan,Ningxia Hui Autonomous Region,their expection for pharmaceutical care by com-munity pharmacists was summarized. RESULTS:Totally 100 residents were interriewed,and 97 completed a full interview with ef-fective interview rate of 97%. Consumers still did not clearly on distinguishing the OTC drugs. The majority of consumers chosen OTC drugs were based on experience and brand,a handful of consumers were under the guidance of community pharmacists. Con-sumers were most concerned about the efficacy,adverse reactions and drug quality in using OTC drugs. Most consumers were not satisfied with the pharmaceutical care in purchasing OTC drugs. Nevertheless,due to a lack of medicine knowledge,consumer had a great demand for pharmaceutical care and willingness to accept it. Low professional level of community pharmacist and staff in current community pharmacy and lack of effective communication between pharmacist and consumer were the obstacles of develop-ing pharmaceutical care. CONCLUSIONS:Because of their distrust on competence of community pharmacist,consumers seek less pharmaceutical care of OTC drugs at community pharmacy though they had expectations on pharmaceutical care of OTC drugs by community pharmacist. Consumers’rely on self-choice of drugs make them exposed to more drug risks.

Objective To investigate the clinical features,diagnosis,treatment and prognosis of gastric neuroendocrine carcinoma (G-NEC).Methods Clinical data of 52 G-NEC cases were analyzed.Follow-up was conducted by telephone.The survival curves were drawn using Kaplan-Meier method.Univariate analysis was performed by the Log-rank test and multivariate analysis was performed by COX proportional hazards model.Results The median overall survival rate was 19 months (range 6 to61 months),and the overall 1,3,5-year survival rates were 74％,16％ and 5％ respectively.Tumor stage surgery,vascular nerve involvement and Ⅲ and Ⅳ phase chemotherapy were related to prognosis (x2 =24.254,10.005,7.261,8.790,all P ＜ 0.05).Multivariate analysis showed tumor stage and vascular nerve involvement were independent prognostic factors (x2 =17.170,5.810,all P ＜ 0.05).Conclusion G-NEC is a highly malignant tumor with poor prognosis.Preoperative diagnosis rate is low.Surgery is the treatment of first choice.Definite diagnosis depends on postoperative pathology and immunohistochemical examination.

Objective To investigate the changes of plasma free carnitine (FC) concentrations in preterm infants supplemented with L-carnitine, and to provide a reference for routine preterm infants L-carnitine supplements. Methods A total of 99 preterm infants supplemented with 10 mg/(kg·d) L-carnitine on days 2 and 5 after birth, and 65 full term infants from Department of Neonatology, the Fifth People′s Hospital of Dongguan during July 2014 to December 2015 were recruited in this study , and filter-paper blood spots were collected by heel prick on days 1, 3 and 7. FC was measured using electron spray ionization (ESI) tandem mass spectrometry (MS-MS). Results Concentrations of FC decreased steadily from day 1 to day 7 in full term infants , while it remained the same level during the first week after birth as at birth. Additionally, concentrations of FC were significantly higher in preterm infants than full term infants on day 1 after birth. Conclusions The reasonable L-carnitine supplements may keep the levels of plasma FC at the levels at birth , which is important for fatty acid metabolism in preterm infants.

OBJECTIVE Epidemic diseases have been recorded in traditional chinese medicine(TCM) for a long time,this paper describes the cognition of TCM on treatment and prevention for epidemic diseases.METHODS This topic was discussed from etiology,pathogenesis,and the process of epidemic diseases in TCM.TCM holds that the occurrence of epidemic diseases is the result of the combined effects of the seasonal and environmental factors,and the internal factor of human body and the epidemic pathogenic factors play the same important role in the process of epidemic diseases.The diagnosis patterns of syndrome differentiation were six meridians,differentiation of Wei,Qi,Ying,and blood,and syndrome differentiation of Sanjiao.RESULTS TCM emphasizes the harmful effects of pathogenic factors on human body,while it pays more attention to the sufficiency of vital Qi defeating the pathogenic factors and the maintenance of human body positive vital Qi.Beside the treatment method,also have some preventive methods been described in TCM,such as different sterilization methods.CONCLUSIONS TCM has its unique system in struggle against epidemic diseases.It is useful and effective in preventing and treating the epidemic diseases.

Objective To explore the value of strain rate and dobutamine stress echocardiography(DSE) in the diagnosis of coronary heart disease. Methods High-dose DSE was performed in 18 patients with coronary heart disease and 10 healthy persons, proved by selected coronary angiography. Ten patients had single coronary lesion, and the other 8 patients had more. By strain rate technology, systolic peak strain rate(SR_ SYS ) was measured in 12 segments of healthy persons and ischemic segments of patients. Results SR_ SYS of healthy subjects enhanced by the increasement of dose of DSE. In patients with single coronary lesion, SR_ SYS enhanced on the first states of baseline, 10 and 20 ?g?kg -1 ?min -1 ,while SR_ SYS changed non-significantly on 30 ?g?kg -1 ?min -1 , and began to decrease on 40 ?g?kg -1 ?min -1 . However in patients with more than one coronary lesions, SR_ SYS of 10 ?g?kg -1 ?min -1 became larger than that of baseline, while SR_ SYS didn't increase any longer on 20 ?g?kg -1 ?min -1 , and fell significantly on 40 ?g?kg -1 ?min -1 . Conclusions Combining stain rate and DSE to quantify local myocardial motion is valuable to offer many important clinic messages, and improves the diagnosis of coronary heart disease.

AlM: To investigate the refractive status of the preschool children in Xiantao, Hubei Province in order to find out the abnormal refraction error beyond the physiological range.
METHODS: ln this cross - sectional study, we investigated preschool children in kindergartens and the scattered ones were 12 716 ( 25 432 eyes ) ranging from 6mo ~ 6 years old. 1 581 children ( 3 162 eyes ) were diagnosed ametropia by Suresight refractive screening instrument, which were confirmed again after mydriasis optometry.
RESULTS: The incidence rate of ametropia in preschool children in Xiantao was 12. 4%, and statistics showed no significant difference between boys and girls (P>0. 05), but had differences of morbility rate among each age group (P<0. 05). With age increasing morbility rate of the refractive error decreased. The simple hyperopia and the compound hyperopia astigmatism were dominant in all refraction error. Professional ophthalmologists diagnosed amblyopia in 261 children (522 eyes), which was 16. 5%, among 1581 abnormal refractive children (3 162 eyes) screened out by Suresight refractive screening instrument.
CONCLUSlON: The incidence rate of ametropia decreases with age increasing in the preschool children from 6mo~6 years old, which imply preschool children should have mydriasis optometry in order to find out amblyopia and other congenital eye disease.

Objective To evaluate prognostic factors for early bronchopleural fistula after pneumonectomy with non small cell lung cancer,and establish a validated clinical model to estimate the risk of early-BPF.Methods We reviewed the medical records of 429 patients who underwent pneumonectomy for NSCLC at our institution.We used univariate and multivariate analysis to identify potential independent risk factors for early-BPF after pneumonectomy for NSCLC.A model to estimate risk of early-BPF was developed by combining independent risk factors.Results The rate of early-BPF after pneumonectomy for NSCLC was 6.5％ (28/429).Three factors were independently associated with early-BPF:neoadjuvant therapy (HR:2.406),bleeding (HR:2.171)and diabetes (HR:1.144).A scoring system for early-BPF was developed by assigning 2 points for each major risk factor (neoadjuvant therapy and bleeding) and 1 point for each minor risk factor(diabetes).Scores were grouped as low (0-1),intermediate (2-3),and high (3),yielding the rate of early-BPF was 14％,27％,and 43％,respectively.Conclusion This clinical model is established on the basis of independent risk factors.This model can be used as a predictive tool for early-BPF after pneumonectomy for NSCLC.

Currently, the basic network resource of the entire traditional Chinese medicine (TCM) industry is fragmented. Issues of data unify are not easily resolved. It seems that there is no new breakthrough in key technologies, especially on the problem of data sharing and resources' integration. In this context, a method of medical information data sharing is advocated to solve the problem. We use the RESTful style to define resources of the pharmaceutical industry, which is based on the UDDI Web services standards. The objective of this paper is to create a method of TCM resource URL defined and exchanged. Finally, this paper provided an easy way for TCM data network sharing.

Objective To investigate the clinicopathological features of renal cell carcinoma (RCC).Methods From December 1956 to August 2012,the clinicopathological features of RCC were studied in 705 cases and related literatures were reviewed.Results The diameter of RCC ranged from 0.6 to 18.0 cm,which the average size was 4.6 cm.The proportions of the clear cell,papillary,multilocular clear cell,chromophobe and unclassified histologic subtype were 88.9％ (627/705),4.1％ (29/705),3.3％ (23/705),1.3％ (9/705) and 2.4％ (17/705),respectively.According to the Fuhrman grading system,the proportions of grade 1,2,3,4 were 19.0％ (116/612),58.3％ (357/612),18.1％ (111/612)and 4.6％ (28/612),respectively.The rates of invasion into the renal pelvis,perirenal fat and vascular were 10.9％ (66/603),10.6％ (64/603) and 4.8％ (29/603),respectively.Of 705 cases,464 (76.6％)cases were in T1,65 (10.7％) cases in T2,73 (12.0％) cases in T3,and 4 (0.7％) cases in T4.As to the lymph node and distant metastasis,the rate was 2.8％ (17/606) and 3.5％ (21/606).The percentages of stage Ⅰ,Ⅱ,Ⅲ and Ⅳ RCC were 74.3％ (450/606),9.9％ (60/606),11.7％ (71/606) and 4.1％(25/606),respectively.The 3-,5-,10-and 15-year disease-specific survival rate for RCC was 92.8％,86.9％,76.8％ and 55.5％,respectively.To those patients with clear cell RCC,the disease-specific survival at the same time point was 92.8％,88.1％,77.4％ and 55.4％,respectively.Multivariate analysis showed that the stage was the only independent prognostic factor for RCC.Conclusions Tumor stage of RCC is the independent prognostic factor for disease-specific survival.The evaluation of renal sinus invasion and lymph node should be noted in the diagnosis of RCC.
