Objective: To identify Persicae Semen and its sibling species, and to secure the quality and clinical safety of this medicinal material. Methods: The internal transcribed spacer 2 (ITS2) of nuclear ribosomal DNA of Persicae Semen and its sibling species were amplified and bidirectionally sequenced by DNA barcoding. Sequence assembly and consensus sequence generation were performed by the CodonCode Aligner 4.1. The genetic distances were computed by MEGA 5.0 in accordance with the Kimura 2-parameter (K2P) model, and the phylogenetic tree constructed by the neighbor-joining (NJ) method. Results: The length of ITS2 sequences of the two origin plants of Persicae Semen was between 212 bp to 213 bp. Their intraspecific genetic distance was much lower than the interspecific genetic distance with their sibling species. The ITS2 sequence possessed the character of good stability and low intra-specific sequence variation. In the NJ tree, both Prunus persica and P. davidiana were clustered into one large branch, and clearly separated with their sibling species. Conclusion: ITS2 can be used to effectively distinguish Persicae Semen from its sibling species, which can provide a reference for the iden-tification of other Chinese medicine and its sibling species.

Germ cells make two major decisions when they move from an indeterminate state to their final stage of gamete production. One decision is sexual commitment for sperm or egg production, and the other is to maintain mitotic division or entry into meiosis. It is unclear whether the two decisions are made as a single event or separate events, because there has been no evidence for the presence of germ cell sex prior to meiosis. Here we report direct evidence in the fish rainbow trout that gonia have distinct sexuality. We show that dazl expression occurs in both male and female gonia but exhibits differential intracellular distribution. More strikingly, we show that boule is highly expressed in male gonia but absent in female gonia. Therefore, mitotic gonia possess sex, sperm/egg decision and mitosis/meiosis decision are two independent events, and sperm/egg decision precedes mitosis/meiosis decision in rainbow trout, making this organism a unique vertebrate model for mechanistic understanding of germ cell sex differentiation and relationship between the two decisions.

Objective? To explore the effects of Roy's cognitive adaptation process theory on pediatric nursing courses. Methods? Totally 119 three-year specialized nursing students who were admitted in 2016 in Nanyang Medical College were selected as the treatment group by convenient sampling, while another 114 specialized nursing students admitted in 2015 were selected as the control group. Nursing students in the control group were taught using the conventional method, whereas nursing students in the treatment group were involved into four-step teaching activities according to Roy's cognitive adaptation process. The Learning Attitude Questionnaire for College Nursing Students and the Critical Thinking Rating Scale were used to evaluate the teaching effects at the end of these courses. Results? At the end of these courses, the treatment group scored higher than the control group on the whole and in different dimensions of the Learning Attitude Questionnaire (P<0.05). The treatment group also scored higher than the control group on the whole and in different dimensions of the Critical Thinking Rating Scale (P< 0.05). Conclusions? Multiple teaching methods based on Roy's cognitive adaptation process, when used in pediatric nursing courses, can enhance nursing students' learning attitude and critical thinking, which is worth promoting in other nursing courses.

Objective:To systematically evaluate the predictive model of intensive care unit (ICU) -acquired weakness so as to provide objective basis for clinical workers to choose appropriate predictive model and provide reference for future model update and new model development.Methods:Sixth databases including PubMed, Embase, web of science, The Cochrane Library, CNKI and Wanfang were searched by the computer. The retrieval time was the construction of the database to October 15, 2019, and the language was limited to Chinese and English. A total of two researchers conducted independent screening of literature, data extraction and evaluated the quality of the included literature in turn, and then used prediction model risk of bias assessment tool (PROBAST) to evaluate the quality of the models included in the literature.Results:A total of 8 articles with high quality were included. The area under the ROC curve of the five models were all greater or equal to 0.7. The model risk of bias assessment showed that only Witteveen's model was rated as low bias, and the remaining 7 models all had a higher risk of bias, but all models had good applicability.Conclusions:The predictive performance of ICU acquired weakness model is good, but there are some biases in development and report. In the future, the whole process of model development and verification should be reported in a standardized way to reduce methodological bias and provide high-quality evidence for clinical practice. Future studies should focus on external validation and updating of models to continuously improve model prediction performance and provide practical models for clinical practice.

Intensive Care Unit (ICU) acquired weakness is a common complication in ICU critically ill survivors. Early intervention is an important measure to prevent and treat ICU acquired weakness. The scientific and standardized intervention has a positive effect on the prognosis of patients. In recent years, integrated care, as a management method for some specific patients, can effectively improve the quality of care, reduce the cost of care, and is gradually applied to the prevention and treatment of ICU acquired weakness. This paper describes the research status of integrated care clinical intervention on ICU acquired weakness, in order to provide the basis for the construction of practical plan of integrated care for ICU acquired weakness.

OBJECTIVES:
This study aimed to investigate the associations of obesity phenotypes with hypertension stages, phenotypes, and transitions among middle-aged and older Chinese.
METHODS:
Using the 2011-2015 waves of the China Health and Retirement Longitudinal Study, we conducted a cross-sectional analysis included 9,015 subjects and a longitudinal analysis included 4,961 subjects, with 4,872 having full data on the hypertension stage and 4,784 having full data on the hypertension phenotype. Based on body mass index and waist circumstance, subjects were categorized into 4 mutually exclusive obesity phenotypes: normal weight with no central obesity (NWNCO), abnormal weight with no central obesity (AWNCO), normal weight with central obesity (NWCO), and abnormal weight with central obesity (AWCO). Hypertension stages were classified into normotension, pre-hypertension, stage 1 hypertension, and stage 2 hypertension. Hypertension phenotypes were categorized as normotension, pre-hypertension, isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), and systolic-diastolic hypertension (SDH). The association between obesity phenotypes and hypertension was estimated by logistic regression. A comparison between different sexes was conducted by testing the interaction effect of sex.
RESULTS:
NWCO was associated with normal→stage 2 (odds ratio [OR], 1.95; 95% confidence interval [CI], 1.11 to 3.42), maintained stage 1 (OR, 1.62; 95% CI, 1.14 to 2.29), and normal→ISH (OR, 1.39; 95% CI, 1.05 to 1.85). AWCO was associated with normal→stage 1 (OR, 1.75; 95% CI, 1.40 to 2.19), maintained stage 1 (OR, 2.77; 95% CI, 2.06 to 3.72), maintained stage 2 (OR, 2.80; 95% CI, 1.50 to 5.25), normal→ISH (OR, 1.56; 95% CI, 1.20 to 2.02), and normal→SDH (OR, 2.54; 95% CI, 1.72 to 3.75). An interaction effect of sex existed in the association between obesity phenotypes and hypertension stages.
CONCLUSIONS
This study highlights the importance of various obesity phenotypes and sex differences in hypertension progression. Tailored interventions for different obesity phenotypes may be warranted in hypertension management, taking into account sex-specific differences to improve outcomes.

OBJECTIVETo explore the prevalence and the different risk factors for asthma in children between urban and rural areas in Fuzhou, Fujian province.
METHODThe epidemiological survey of asthma in 0-14 years old children was conducted from October 2009 to October 2010 between Fuzhou urban and rural areas in Fujian province. The investigation subjects were selected in urban and rural areas by phased stratified random cluster sampling. The 2010 third national epidemiological survey questionnaire of children with asthma was used for screening for possible patients. Diagnosis of asthma was confirmed by physical examination. The children with asthma were designated as the positive cases, while non asthmatic children who were age, gender, ethnic, and living environment matched with asthmatic patients were designated as negative control. Comparison of the prevalence of asthma in children between Fuzhou urban and rural areas was performed. The influencing factors of asthma were analyzed and screened by the regression equation model of two element Logistic regression.
RESULTTotally 12 235 questionnaires of children with asthma and allergic disease screening were issued and 11 738 questionnaire were sent back (6 221 were male and 5 517 were female). The return rate was 95.9% in urban Fuzhou; 648 children were diagnosed as asthma. The prevalence of asthma in male was 6.48% and female children was 4.44% (comparison of the prevalence of gender χ(2) = 23.267, P < 0.001) in urban areas . A total of 6 000 questionnaires of children with asthma and allergic disease screening were sent out and 5 860 were responded (male children 3 228, female children 2 632). The recovery rate was 97.7% in rural Fuzhou; 135 children with asthma was diagnosed. The prevalence of asthma in male was 2.73%and female children and was 1.79%. Adding protein supplement before 6 months (OR = 1.908, 95%CI:1.233-2.959), the use of antibiotics in the treatment of asthma (OR = 14.541, 95%CI:8.920-23.705), furniture materials (non wood) (OR = 2.432, 95%CI:1.563-3.785) were the main risk factors of children with asthma in urban. Adding protein supplement before 6 months(OR = 3.021, 95%CI:1.357-6.711), the use of antibiotics in the treatment of asthma(OR = 14.784, 95%CI:3.842-56.885), the use of coal as fuel (OR = 63.339, 95% CI: 7.993-501.943), domesticated livestock (OR = 13.659, 95% CI:1.342-139.068), the family smoking before and after birth (OR = 6.226, 95%CI:2.674-14.495) and chemical fiber pillow (OR = 3.638, 95%CI:1.241-10.666) were the main risk factors of children with asthma in rural areas.
CONCLUSIONThe prevalence of children with asthma in urban areas was higher than that in rural areas. The prevalence of asthma in male children was higher than in female children. Adding protein food supplement before 6 months, the use of antibiotics and non solid wood furniture material were the main risk factors in children with asthma in urban areas. Adding protein supplement before 6 months, the use of antibiotics, domesticated livestock, the use of coal as fuel and the family smoking before and after birth were the main risk factor of asthma in children in rural areas.
