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 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 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 To investigate the accuracy of image registration with computed tomograpby (CT) and magnetic resonance imaging(MRI) and to determine gross tumor volume(GTV) of hepatocellular carcinoma(HCC).Methods Thirteen patients were enrolled in this study.CT image was taken in inhala tion phase,and MRIT2 image at the time of peak exhalation.Additional MRIT2 image was taken by fast scanning(MRIT2F) in peak inhalation phase in 6 patients.After mutual information method to CT/MRI im age registration,manual adjustment was made to optimize the accuracy of image fusion.The GTV and liver of each patient was independently contoured by two observers on CT,MRIT2 and MRIT2F images.The accura oy of image fusion was assessed by the ratio of liver overlap(P-LIVERCT-MRIAT2 ,P-LIVERCT-MRIT2F) ,and the dis tance between bone markers(DCT-MRIT2,DCT-MRIT2F) of CT and MRI on the fused image.The volumes of GTV contoured on CT (V-GTVCT),MRIT2 (V-GTVMRIT2),MRIT2F (V-GTVMRIT2F) and their overlap (V GTVCT-MRIT2,V-GTVCT-MRIT2F) and composite volumes (V-GTVCT+MRIT2,V-GTVCT+MRIT2F)were measured.The percentage of V-GTVCT and V-GTVMRIT2 on V-GTVCT+MRIT2,V-GTVCT and V-GTVMRIT2F on V-GTVCT+MRIT2F,V GTVCTMRIT2 and V-GTVCT-MRIT2F on V-GTVCT was also calculated,respectively.Results The mean DCT-MRIT2 and DCT-MRIT2F were 2.7±0.8 mm and 2.1Q±0.9mm.The mean P-LIVERCT-MRIT2 and P-LIVERCT-MRIT2F were 85.9% ± 4.1% and 92.7%± 1.5%.Interobserver difference was significant for GIN defined by CT,but not by MRIT2.V-GTVCT,V-GTVMRIT2 and V-GTVMRIT2F were 387±396 cm3 ,488 ±461 cm3 and 597 ±541 cm3 ,respectively.The percentage of V-GTVCT and V-GTVMRIT2 on V-GTVCT+MRIT2 was 66.2%±13.5% and 88.7% ± 10.2% ,while V-GTVCT and V-GTVMRIT2F on V-GTVCT-MRIT2F was 71.3%±12.7% and 93.5%± 4.8%,respectively.Conclusions CT and MRI for image fusion should be obtained in the same respirato ry phase and in the same treatment position.Automatic registration using mutual information method by auto matic registration software is useful.CT and MRI image should be integrated for HCC GTV delineation.GTV used for planning should be the sum of CT-defined GTV and MRl-defined GTV.

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 evaluate the value of three-dimensional power Doppler imaging(3D-PDI) in the discrimination between benign and malignant endometrium in women with postmenopausal bleeding. Methods Eighty-four women with post menopausal bleeding who examined by 3D-PDI were enrolled. All patients scheduled for pathological examination were divided into benign group (30 cases with endometrial polyps and 34 cases with hyperplasia) and malignant group (20 cases with endometrial carcinoma). Endometrial volume, vascularity index ( VI) , flow index ( FI) and vascularity flow index ( VFI) were measured. The diagnostic value of parameters derived from 3D-PDI was evaluated by using the receiver operating characteristic ( ROC) curve. Results Differences of these parameters (VI, FI and VFI) were considered statistically significant between two groups, the parameters of endometrial volume had no significant differences between two groups; the area under ROC curve(AUC) of the meaningful data were 0.976,0.888 and 0.894 respectively. Among these parameters, VI had the highest diagnostic value for discriminating between benign and malignant endometrium, the cut-off value of which was 2. 97 with a sensitivity of 95% and a specificity of 86%. Conclusions 3D-PDI is a good diagnostic tools in the discriminations between benign and malignant endometrium in women with postmenopausal bleeding.

Objective To understand the clinical characteristics of elderly patients aged 60 years and over in Anhui Province who receive maintenance hemodialysis (MHD).Methods Clinical data of MHD patients in hemodialysis centers of 26 hospitals in Anhui Province from March 31, 2014 to January 1, 2014 were collected.With non-elderly MHD patients (aged over 18 old and under 60) serving as controls, similarities and differences in the primary disease, vascular access, nutritional status, mineral and bone disorders (MBD), and other related aspects in MHD patients were compared.Results The top three original diseases for elderly patients were chronic glomerulonephritis (CGN) (32.8 ％), hypertensive nephrosclerosis (HNS) (27.7 ％) and diabetic nephropathy (DN) (26.2％).The proportion of patients with DN and HNS in the elderly was higher than in the control group (P ＜ 0.001).Vascular access types in elderly MHD patients were arteriovenous fistula (AVF) (89.4 ％), tunneled cuffed catheter (TCC) (8.9 ％), and temporary venous catheter (1.3％).The proportion of patients with AVF was lower (P＜0.001) and the proportion of patients with TCC was higher (P＜0.001) in the elderly group than in the control group.The incidence of anemia was higher in the elderly patients than in the control group (P＜0.05);the proportion of elderly patients with hemoglobin (Hb) levels was 30.3％, in which had no significant difference as compared with the control group (P ＞ 0.05).The incidence of hypoalbuminemia was 21.2％ in elderly patients, which was higher than in the control group.The proportions of elderly MHD patients with normal levels of adjusted serum calcium, serum phosphorus, and intact parathyroid hormone (iPTH) were 52.0％, 27.9％ (higher than in the control group, P＜0.001), and 47.9％, respectively, while there was no difference in adjusted serum calcium and iPTH between the two groups (P＞0.05).The treatment rates for low serum calcium,hyperphosphatemia and secondary hyperparathyroidism (SHPT) in elderly patients were 50.6％,51.6％ and 71.5％, respectively, which had no significant difference as compared with those in the control group (P＞0.05).Conclusions Elderly patients with MHD show distinct characteristics in primary diseases, vascular access types, and nutrition and MBD status, including higher proportions of HNS and DN as their primary diseases.The type of vascular access is still dominated by AVF, and the proportion of TCC is higher.The nutritional status is poor, with a lower incidence of high phosphorus and a higher incidence of low iPTH.Efforts should be made to promote compliance in elderly patients to better control MBD, improve nutritional status and increase safety and effectiveness of treatment.

Objective:To compare the effects of rotational night shifts on the micturition patterns of fe-male nurses.Methods:A total of 58 nurses without lower urinary tract symptoms were recruited,who worked in the Peking University People’s Hospital during January and June in 2014.The nurses aged 20 -43 years were divided into two groups,the night-shift group (n =28)and the non-shift group (n =30).The alcohol or coffee intaking were forbidden.In the night-shift group,nurses had worked on rota-tional shifts for at least 6 months.Their average age was (26.75 ±4.11)years.In the non-shift group, nurses took regular day-time work,whose average age was (27.80 ±5.60)years.A voiding diary was kept for 7 consecutive days at the end of 6 months,starting 2 days before their night duties until 4 days after completion of their night duties.For comparison,the non-shift group with regular shifts completed a 7-day voiding diary.In the 7-day recording voiding diary,the nurses were required to have the normal in-take of liquid about 1 500 -2 000 mL/d.The frequency volume charts of nocturia,the 8-hour interval urine production and frequency were compared between the two groups.Results:Nocturia frequency was increased in the night-shift group [0.5 (0 -2.4)]compared with the non-shift group [0 (0 -2),P =0.02].The volume of nocturia was increased in the night-shift group [125 mL (0 -660 mL)]compared with the non-shift group [0 mL (0 -340 mL),P <0.01].The 8-hour interval indices showed that urine production changed with shift (P <0.01).In the consecutive 7 days,the nocturnal volume of the night-shift group increased on the day after night shift.When the night-shift nurses returned to daytime duty, the volume of urine decreased but nocturnal urine production remained high,and the frequency of noctu-ria also increased significantly (P <0.05).Compared with the 8-hour interval indices,the night-shift group’s voiding volume [(542.35 ±204.66)mL]and voiding frequency (2.24 ±0.69)were more than those of the non-shift group at the afternoon time (from 2 pm to 10 pm).During the 8 h interval night time (from 10 pm to 6 am),the volume of nocturia in the night-shift group [(309.74 ±162.74) mL]was more than that in the non-shift group [(199.38 ±153.98)mL,P =0.01];the frequency of nocturia in the night-shift group (1.31 ±0.52)was increased than that in the non-shift group (0.82 ± 0.55,P <0.01).Conclusion:The rotational shifts affect the micturition patterns of nurses who go through the night shift work,which increases the volume and frequency of the nocturia.

Objective:To investigate the impact of preoperative urodynamic study on the diagnosis and treatment for female patients with clinical diagnosis of stress urinary incontinence by studying their diag-nosis and treatment database,and to assess its clinical significance of urodynamic study.Methods:From April 2011 to December 2015,196 female patients diagnosed clinically with stress urinary incontinence underwent preoperative urodynamics study,after excluding pelvic organ prolapse.The preoperative uro-dynamic data of these 196 cases were analyzed and the clinical significance of urodynamics on differential diagnosis and treatment for the female patients with stress urinary incontinence was evaluated.Results:In this study,23 cases (11.73%)changed or amended their diagnoses by the urodynamic study,which were inconsistent with the previous clinical diagnoses concluded by the symptoms,physical examinations, and lab tests.A total of 10 cases underwent a different surgery or conservative treatment instead of the original treatment according to urodynamic study.Of them,3 were diagnosed as detrusor overactive and undertook conservative treatment;3 were diagnosed as bladder outlet obstruction plus stress urinary in-continence and were undertaken the transurethral resection of the bladder neck (TURBN)plus tension free vaginal tape (TVT);2 were diagnosed as bladder outlet obstruction plus stress urinary incontinence and were undertaken TURBN alone;1 was diagnosed as bladder outlet obstruction plus stress urinary in-continence and was undertaken TURBN plus tension free vaginal tape obturator (TOT);1 was found no abnormal bladder function turned out to be interstitial cystitis and went for a bladder instillation of drug. The changed treatments avoided the risk of dysuria or residual urine increased after operation due to inap-propriate surgical methods.Conclusion:In order to make a correct diagnosis and suitable treatment for female patients with stress urinary incontinences,the preoperative urodynamic study is necessary besides detailed medical history,physical examination,and laboratory tests.With the help of the urodynamic study,the concomitant diseases of patients with stress urinary incontinence may be detected,the individualized treatment regimen can be developed,and more importantly,the inappropriate surgical de-cision can be avoided.
