Objective To design a kind of aseptic drainage device with safe practice and accurate measurement for clinical nurses. Methods The experiment group included 63 cases using drainage device with accurate measurement,and control group included 63 cases using disposal drainage bag with scale of visual measurement.The accuracy of drainage liquid measurement was compared between two groups,and bacterial culture was made for the drainage liquid of two groups.Results The measurement error of experiment group and control group was(3.31±1.8)mL and(56.0±5.8)mL,respectively.The difference was significant(t=-4.593,P<0.01).The bacterial culture results showed no obvious difference between two groups(positive rate were 15.9%vs 17.5%,χ2=0.057,P>0.05). Conclusion The accurately measured aseptic drainage device is convenient for nurses to practice in clinics,and its application can reduce workload of nurses and decrease the occurrence of pollution.

The shape and structure of granules are controlled by the granulation process, which is one of the main factors to determine the nature of the solid dosage forms. In this article, three kinds of granules of a traditional Chinese medicine for improving appetite and promoting digestion, namely, Jianwei Granules, were prepared using granulation technologies as pendular granulation, high speed stirring granulation, and fluidized bed granulation and the powder properties of them were investigated. Meanwhile, synchrotron radiation X-ray computed micro tomography (SR-µCT) was applied to quantitatively determine the irregular internal structures of the granules. The three-dimensional (3D) structure models were obtained by 3D reconstruction, which were more accurately to characterize the three-dimensional structures of the particles through the quantitative data. The models were also used to quantitatively compare the structural differences of granules prepared by different granulation processes with the same formula, so as to characterize how the production process plays a role in the pharmaceutical behaviors of the granules. To focus on the irregularity of the particle structure, the box counting method was used to calculate the fractal dimensions of the granules. The results showed that the fractal dimension is more sensitive to reflect the minor differences in the structure features than the conventional parameters, and capable to specifically distinct granules in structure. It is proved that the fractal dimension could quantitatively characterize the structural information of irregular granules. It is the first time suggested by our research that the fractal dimension difference (Df,c) between two fractal dimension parameters, namely, the volume matrix fractal dimension and the surface matrix fractal dimension, is a new index to characterize granules with irregular structures and evaluate the effects of production processes on the structures of granules as a new indicator for the granulating process control and optimization.

Objective: To explore the effect of reproductive health education on health literacy of hospitalized female adolescents,and to provide reference for the protection of their physical and mental health. Methods: A total of 102 female adolescents who were hospitalized in department of gynaecology from January 2019 to December 2019 were selected for reproductive health education and questionnaire survey. Results: There were 65 cases of unplanned pregnancy (4 cases of tubal pregnancy), 18 cases of gynecological tumor (1 case of ovarian malignancy), 11 cases of gynecological inflammation (1 case of tubal abscess), and 8 cases of abnormal uterine bleeding (2 cases of blood transfusion).Eighty-six patients (84.3%) were treated surgically, 7 cases had their ovaries and/or fallopian tubes removed. After reproductive health education,health literacy of menstruation and ovulation, reproductive organ tumor, gynecological inflammation(inducing factors,clinical manifestations,harmfulness), harm of premature sexual life, scientific contraception, sexually transmitted diseases(types,transmission routes,preventioe measures), abortion hazard(short-term and longterm complications) and necessity of health examination improved significantly(χ2=14.8, 25.1, 15.7, 30.6, 18.6, 25.9, 31.1, 17.8, 19.1, 15.2, 40.1, 58.6, 69.8, P<0.05). Conclusion The lack of reproductive health knowledge of female hospitalized adolescents may lead to unplanned pregnancy, tumor, inflammation and abnormal uterine bleeding.Reproductive health education can significantly improve the health literacy of female adolescents and ensure their physical and mental health.

OBJECTIVE To investigate and analyze the pharmaceutical care needs of the elderly， thus providing a reference for improving the pharmaceutical care for the elderly. METHODS Based on the Kano model， a questionnaire was designed， and 1 200 community-dwelling elderly in the main urban area of Chongqing were selected as the survey subjects. The study analyzed the attributes and urgency of their pharmaceutical care needs to put forward optimization strategies. RESULTS A total of 1 200 questionnaires were distributed in the study， and 1 062 valid questionnaires were collected， with an effective response rate of 88.50%. The gender distribution of respondents was relatively balanced， with the majority aged between 60 and 69 （43.41%）， and generally possessing a relatively low level of educational attainment. The results showed that medication education and medication consultation were must-be needs； home-based pharmaceutical care was an expected need； drug reorganization， medication monitoring， pharmaceutical science popularization， and pharmaceutical ward round were attractive needs； internet-based pharmaceutical care was indifferent need. The urgent order of demand was medication education ＞ medication consultation ＞ home-based pharmaceutical care ＞ pharmaceutical science popularization ＞ drug reorganization ＞ medication monitoring ＞ pharmaceutical ward round ＞ internet-based pharmaceutical care. CONCLUSIONS The community elderly in Chongqing have high expectations for pharmaceutical care as a whole. Medical institutions should fully guarantee the two essential needs of medication education and medication consultation， and focus on ensuring the expected needs for home-based pharmaceutical care. Efforts should be made to develop the four attractive needs of pharmaceutical science popularization， drug reorganization， medication monitoring， and pharmaceutical ward round， and actively carry out age-friendly adaptations for internet-based pharmaceutical care.

Objective:To investigate the acceptance and attitude toward a novel fecal immunochemical test (FIT) in colorectal cancer screening among populations in China.Methods:From May 2018 to May 2019, 2 474 people aged 50-74 years were recruited from five provinces of China (Zhejiang, Anhui, Jiangsu, Hunan and Yunnan). The general demographic characteristics, acceptance of the new FIT technology and operational difficulties through the whole screening process were obtained through questionnaire survey. Multivariate logistic regression model was used to analyze the factors related to difficulties encountered in sampling stool, reading and uploading results.Results:The subjects were (60.0±6.4) years old, and female, high school of above educated, unemployed/retired/other, married and with medical insurance status of “new rural cooperative medical care (NRCMC)” accounted for 61.7% (1 526), 29.0%(718), 34.3% (849), 92.7% (2 293) and 31.3%(775), respectively. The population's acceptance of the FIT technology was 94.8%. In the process of FIT screening, the percentage of occurred difficulties in sampling stool, reading and uploading results were 33.1% (819), 46.4% (1 147) and 62.9% (1 557), respectively. The main difficulties were the uncertainty about whether the sampling operation was standard (28.0%), the inability to accurately judge the result displayed (32.5%) and the need for help without using a smartphone (44.2%). The results of multivariate logistic regression model analysis showed that people aged 65-74 years old and with medical insurance status of “NRCMC” were more likely to encounter difficulties in sampling, and those who were unemployed/retired/other and living with 3 or more family members were less likely to encounter difficulties in sampling. Those aged 65-74 years old, farmers or migrant workers, and those with “NRCMC” were more likely to encounter difficulties in readingresults, and those with 3 or more family members were less likely to encounter difficulties in reading result. Those with “NRCMC” were more likely to encounter difficulties in uploading results, and those with education level of high school or above, living with more than 3 family members were less likely to encounter difficulties in uploading results.Conclusion:The acceptance of the new FIT technology is relatively high among the subjects. Age, education level, occupation, number of family members living together and medical insurance status might be related to difficulties encountered in sampling stool, reading and uploading results, and it can be further strengthened in terms of the technology and characteristics of sub-populations.
