Objective To further understand factors that influence health-related quality of life (HRQOL) in patients with ulcerative colitis (UC),especially the role of perceived stress and coping modes in Chinese patients with UC.Methods This study was a cross-sectional study.Patients with UC were recruited from July 2013 to September 2014 in Peking Union Medical College Hospital.HRQOL was measured using the inflammatory bowel disease questionnaire (IBDQ).Perceived stress was measured by Perceived Stress Scale (PSS).Coping strategy was evaluated using Medical Coping Modes Questionnaire (MCMQ).Demographic data,course of the disease,clinical disease activity,and disease phenotype according to Montreal classification were also collected.Univariate analyses were conducted to determine which variables were associated with HRQOL,and those were statistically significant were entered into a multivariate regression model.Results We recruited 214 patients (response rate 92.2％),whose median age was 37.5 (29.0,49.3) years old and median course of UC was 4 (2,9) years.Through univariate analyses,better HRQOL was significantly associated with regular medical visits,lower number of previous relapses and hospitalizations,no steroid use,Montreal E1,lower Mayo scores,clinical remission,less perceived stress and less acceptance strategy use.However,multivariate analyses revealed that perceived stress (OR =1.112,95％ CI 1.058-1.169),acceptance (OR =0.310,95％ CI 0.141-0.685),number of hospitalizations (OR =2.924,95 ％ CI 1.328-6.437) and clinical activity (OR =5.058,95 ％ CI 2.312-11.066) were most strongly related to HRQOL.Conclusions HRQOL of UC patients are not only associated with clinical activity of the disease,but also associated with coping strategy and perceivedstress.Further research needs to focus on whether or not relieving stress and guiding patients to cope with ulcerative colitis would improve HRQOL.

This study was aimed to solve the problem of overall syndrome differentiation information collection on patient’s main complain of traditional Chinese medicine (TCM) four diagnostic methods, in order to make syndrome differentiation standard of premenstrual syndrome (PMS) with liver-qi invasion pattern. The method of cluster sampling was applied in the investigation. The appropriate structural equation modeling (SEM) was established according to multi-dimension indexes of case features and TCM theories. The results of the “information acquisition form for doctor” structural equation showed that emotion dimension, body-symptom dimension, organism condition dimension load coefficients were 0.715, 0.574 and 0.904, respectively. The results of the “information acquisition form for patient” structural equation showed that emotion dimension, body-symptom dimension, organism condition dimension load coefficients were 0.705, 0.945 and 0.848, respectively. There were strong relativities among all dimensions. Combined with TCM theories, the main symptom of identified PMS with liver-qi invasion pattern was “irritable and angry”. And the secondary symptoms contained headache, breast tenderness, distention and pain of lower abdomen and stomach. The combining symptoms were insomnia, dreaminess, swelling of extremities, fatigue, inefficiency for work and housework, hard to focus the attention. It was concluded that the combination of information acquisition method from both the doctor and patient established a relative comprehensive information acquisition system. It established the syndrome differentiation standard of PMS with liver-qi invasion pattern for the first time based on epidemiologic investigation. It provided important reference for the study of PMS subtype.

Objective The article was to speed up the dissolution rate of poorly soluble drugs, reduce the configuration time and improve the allocative efficiency by analysis on factors influencing dissolution and adoption of proper allocative approaches accord-ing to different characteristics of insaluble drugs. Methods 5 insaluable drugs were chosen for the study, which were ornithine as-partate, mezlocillin sodium and sulbactam sodium, teicoplanin, omeprazole sodium injection and imipenem and cilastatin sodium.The control group were allocated by routine configuration approach, while the experiment group were improved by increasing the amount of solvent, loosing the powder inside the bottle before configuration, reducing the bubble, adopting special solvent and increasing the dis-solution temperature.Observation and comparative experiment were made on two groups along with the timing from configuration to com-plete dissolution into clear transparent liquid. Results As to the average complete dissolution time of 5 drugs, significant difference was found between two groups([42±5]s vs [246±35]s, [3±1]min vs [30±3]min, [5±1]min vs [10±3]min, [5±3]min vs [10± 5]min, [2±1]min vs [10±1]min, P<0.05).Compared with the control group, the dissolution time of 5 drugs was cut down by 83%, 90%, 50%, 50%, 80%in experiment group. Conclusion Appropriate increase of solvent, loose powder, bubble reduction, special solvent and increased solution temperature contribute to shortening the dissolution time of insoluble drugs and improving the configura-tion efficiency of pharmacy intravenous admixture.

Objective To analyze the epidemiologic features of visceral leishmaniasis in different age groups in China from 2005 to 2012,and to provide a scientific basis for prevention and treatment of the disease.Methods The visceral leishmaniasis cases were obtained from China disease epidemic monitoring information system from 2005 to 2012.All the cases were divided into subgroups by demographic characteristics:infant (＜1 year old),childcare (≥1 and ＜4 years old),child (≥4 and ＜15 years old),adult (≥15 and ＜65 years old) and senior adult (above 65 years old).The epidemiologic features,such as gender,season of disease onset and area distribution of visceral leishmaniasis were analyzed.Results The total reported visceral leishmaniasis from 2005 to 2012 were 2 979,among which cases in infant,childcare,child,adult and senior adult were 24.9％,21.7％,20.0％,32.4％ and 1.0％,respectively.Infant cases were most reported in April; childcare cases in December which began to increase since September; child cases in October and adult and senior adult in March.The reported cases were mainly from Xinjiang,Gansu and Sichuan areas.However,age characteristics differed among regions,which were mainly infants,both childcare and children,and adults,respectively in this three areas.The duration from onset to diagnosis was shortest in infant group (11 d) and longer in adult group (15 d).Conclusions The number of visceral leishmaniasis cases in different age groups peaks in different months.Regional distribution is not even.Cases are most concentrated in Xinjiang,Gansu and Sichuan areas.Infants predominate in Xinjiang,childcare and children in Gansu and adults in Sichuan.

The endocytosis/phagocytosis of calcium alginate nanocapsules by peripheral blood derived dendritic cells was confirmed with the use of Quantum dots labeling.Results further demonstrated these nanoparticles could cause the upregulation of HLA-DR expression to induce the maturation of dendritic cells in vitro.Dendritic cells stimulated by nanocapsules covalently loaded with BSA were shown to stimulate the proliferation of self T cells with blank capsules and free BSA as controls,suggesting their potential applications in cancer cell therapy as a new antigen delivery vehicle with a strong adjuvant effect.
