Objective·To explore the effect of continuous nursing based on EMS[environment management(E),medicine direction(M)and self monitoring(S)]management mode on the preschool children with asthmatic diseases.Methods·A total of 67 children aged 0 to 6 years with asthmatic diseases admitted to the Department of Respiratory Medicine,Shanghai Children's Hospital,Shanghai Jiao Tong University School of Medicine from December 2019 to November 2020 were selected and divided into observation group(33 cases)and control group(34 cases)according to the random number table method,with 3 cases lost,and finally 32 cases in each group.The observation group received continuous nursing care based on EMS management mode,while the control group received routine care and discharge follow-up through the telephone.The children in the two groups were followed up at 1,3,and 6 months after discharge to evaluate the results of Test for Respiratory and Asthma Control in Kids(TRACK)and wheezing recurrence;Medication Adherence Report Scale for Asthma(MARS-A)and Nursing Job Satisfaction Questionnaire were used to evaluate medication adherence and nursing job satisfaction 6 months after discharge.Results·There was no significant difference in demographic characteristics and clinical baseline characteristics between the two groups.Repeated measures analysis of variance showed that effects of time,groups and the interaction of groups×time on the total score of TRACK were statistically significant.The total scores of TRACK in the observation group were significantly higher than those in the control group at 1,3,and 6 months after discharge(P=0.000).The total scores of TRACK in the two groups gradually increased with time(P=0.000).The recurrence rates of wheezing in the observation group were 25.0%,18.7%,and 9.4%at 1,3,and 6 months after discharge,which were significantly lower than those in the control group(50.0%,43.7%,and 31.3%,respectively,P<0.05).Generalized estimating equation analysis showed that there was a statistically significant difference between the two groups(P=0.013),and the intervention effect of the observation group was better than that of the control group(OR=0.292).The MARS-A score of the observation group was 4.519±0.395 at 6 months after discharge,which was significantly higher than that of the control group(3.994±0.739,P=0.001).The nursing job satisfaction of the observation group was significantly higher than that of the control group(P=0.000).There was a moderate positive correlation between the MARS-A score and the nursing job satisfaction(r=0.389,P=0.001).Conclusion·Continuous nursing based on EMS management mode can significantly improve the medication compliance and wheezing control level of the preschool children with asthmatic diseases,significantly reduce the recurrence rate of wheezing,and improve the nursing satisfaction.

RNAs are involved in the crucial processes of disease progression and have emerged as powerful therapeutic targets and diagnostic biomarkers. However, efficient delivery of therapeutic RNA to the targeted location and precise detection of RNA markers remains challenging. Recently, more and more attention has been paid to applying nucleic acid nanoassemblies in diagnosing and treating. Due to the flexibility and deformability of nucleic acids, the nanoassemblies could be fabricated with different shapes and structures. With hybridization, nucleic acid nanoassemblies, including DNA and RNA nanostructures, can be applied to enhance RNA therapeutics and diagnosis. This review briefly introduces the construction and properties of different nucleic acid nanoassemblies and their applications for RNA therapy and diagnosis and makes further prospects for their development.

Objective:To investigate the influence of trimethylamine N-oxide(TMAO)on the development of early neurological deterioration(END)in diabetic patients with acute ischemic stroke.Methods:In this cross-sectional study, 108 type 2 diabetes patients with acute ischemic stroke treated at the Department of Neurology in the Affiliated Wuxi People’s Hospital of Nanjing Medical University between October 2019 and November 2020 were consecutively recruited.END was defined as an increase in the National Institutes of Health Stroke Scale(NIHSS)≥ 2 points and exclusion of intracranial hemorrhage or bleeding transformation in cranial imaging evaluation within 5 days of initial deterioration of neurological dysfunction.The patients were divided into 2 groups, an END(n=36)group and a non-END group(n=72). Fasting plasma TMAO was measured using isotope dilution liquid chromatography coupled to tandem mass spectrometry.Results:Of the 108 patients, 36(33.3%)were diagnosed with END, and their plasma TMAO levels were significantly higher compared with patients without END( Z=-3.500, P<0.001). For prediction of END, the area under the ROC curve for plasma TMAO levels was 0.707(95% CI: 0.603-0.811, P<0.001). The frequencies of END in subjects grouped via tertiles of TMAO were 22.2%, 19.4% and 58.3%, respectively, with significant differences between the 3 groups( χ2=14.979, P=0.001). Univariate analysis showed that elevated TMAO( OR=1.160, 95% CI: 1.050-1.282, P=0.004)was associated with END.A multivariate logistic regression model further confirmed the association between TMAO and END( OR=1.145, 95% CI: 1.033-1.269, P=0.010). Conclusions:Increased plasma TMAO levels are associated with END in diabetic patients with acute ischemic stroke.

Cutaneous sterile pustulosis is categorized as a non-infectious and non-follicular impetigo, with a low prevalence and difficulty in the treatment.Deficiency of interleukin(IL)-36 receptor antagonist (DITRA) is an auto inflammatory disease featured by the decreased interleukin-36 receptor antagonist (IL-36Ra) activity caused by IL36 RN mutation.Functional or structural defects of IL-36Ra increase the secretion of inflammatory and pro-inflammatory factors by keratinocytes, macrophages and dendritic cells.Upregulation of IL-36 receptor agonists induce type 17 helper T lymphocytes to secrete IL-17, which is essential for the onset of multiple subtypes of aseptic pustulosis.Research on the relationship between DITRA and cutaneous sterile pustulosis is important for developing targeted therapies.

Objective To investigate the potential mechanism of Rhizoma Coptidis extracts (RCE) against sepsis associated with acute kidney injury. Methods C57BL/6 mice were divided into sham group, model group and RCE treatment group. The levels of Scr and BUN were measured by test kits. Gas chromatography-mass spectrometry was used to analyze metabolic changes in kidneys. Results The levels of Scr and BUN were increased in the model group than sham, which were reversed by RCE. 16 metabolites related to the progress of sepsis associated with acute kidney injury were detected, which were involved in amino acid metabolism and carbohydrate metabolism. Among these metabolites, the level of 8 metabolites can be reversed with RCE treatment. Conclusion RCE might exert therapeutic effects in sepsis associated with acute kidney injury by altering multiple metabolic pathways.

Objective:To elucidate the effects of andrographolide (AG) against acute pancreatitis (AP)-associated kidney injury and explore the potential mechanism.Methods:Thirty-two C57BL/6 mice were divided into control group, AP group, AG treatment group and AG control group. In AP group, AP model was established by intraperitoneal injection of L-arginine and LPS. AG treatment group was intravenously injected with AG 8 h before the model establishment. The control group was intraperitoneally injected with an equal volume of normal saline. The AG control group was intravenously injected with AG 8 h before the intraperitoneal administration of normal saline. Venous blood of inner canthus in mice was collected, and the levels of amylase, creatinine (Scr) and urea nitrogen (BUN) in serum were detected. Pancreatic and double kidney tissues were also collected. Pancreatic myeloperoxidase (MPO) activity was detected by colorimetry. Histopathological changes of pancreas and kidneys were observed under light microscope and pathological score was evaluated. Ultra-high-performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry was used to analyze metabonomics in renal tissue.Results:Compared to the control group, the levels of amylase, Scr and BUN in serum and pancreatic MPO activity in the AP group were obviously increased [(13.78±6.01)U/L to (0.23±0.04)U/L, (79.81±24.03)μmol/L to (9.02±2.87)μmol/L, (34.76±14.53)mmol/L to (8.52±2.55)mmol/L, (16.55±4.23)U/g pro to (2.32±0.55)U/g pro]; histopathologic scores of pancreas and kidney in the AP group were also increased (2.70±0.26 to 0.20±0.12, 3.00±0.35 to 0.30±0.12), and the differences were statistically significant (all P<0.05). The levels of amylase, Scr and BUN in serum and pancreatic MPO activity in the AG treatment group were decreased than the AP group [(8.26±3.87)U/L to (13.78±6.01)U/L, (55.42±17.25)μmol/L to (79.81±24.03)μmol/L, (20.66±10.30)mmol/L to (34.76±14.53)mmol/L, (11.51±3.29)U/g pro to (16.55±4.23)U/g pro]; histopathologic scores of pancreas and kidney were also decreased in the AG treatment group than those in the AP group (1.40±0.19 to 2.70±0.26、1.70±0.26 to 3.00±0.35), and the differences were statistically significant (all P<0.05). Metabonomics analysis detected a total of 31 metabolites. Most of metabolites were involved in amino acid and fatty acid metabolism, and a few of them were also involved in glucose, nucleotide, vitamin and bile acid metabolism. Conclusions:AG exerts protective effects on AP-associated kidney injury by altering the levels of multiple metabolites.

BACKGROUND: Studying the relationship between flexibility and body composition of college students is of great significance for enhancing the levels of physical health and sports. OBJECTIVE: To investigate the relationship between sit-and-reach and body composition of college students in Guangxi Zhuang Autonomous Region and differences between sexes. METHODS: Totally 2 175 students from a Guangxi university were randomly selected. Body composition was determined by the MC-180 body composition tester. The students were divided into four groups: ≤ 12.10 cm group,＞ 12.10-16.40 cm group,＞ 16.40-20.70 group and＞ 20.70 group according to quartile of sit-and-reach measured in accordance with the National Physical Health Test Standard. All data were processed by SPSS 22.0 software. RESULTS AND CONCLUSION: Sit-and-reach was significantly correlated with body mass index, percentage of body fat, fat-free mass index, upper limb lean mass and lower limb lean mass (P ＜ 0.05), and percentage of body fat was negatively correlated with sit-and-reach (P ＜ 0.05). The body mass index, fat-free mass index, upper limb lean mass and lower limb lean mass in the ≤ 12.10 cm group were significantly lower than those in the other groups. Fat-free mass index and upper limb lean mass were correlated with sit-and-reach in male college students (P ＜ 0.05). The fat-free mass index and upper limb lean mass in the＞ 16.40-20.70 cm group were significantly higher than those in the ≤ 12.10 cm group. Therefore, there is a positive correlation between the flexibility and fat-free mass index and upper limb lean mass in college students.

Lung cancer is one of the most important malignant tumors in the world. The morbidity and mortality rank the first in all kinds of cancer. Long non-coding RNA (lncRNA) is at least 200 nt long and has no protein coding capacity. It plays an important role in the epigenetic regulation, cell cycle regulation, the regulation of cell differentiation, and many other life activities. The studies indicate that dysregulation of lncRNAs in non-small cell lung cancer (NSCLC) tissue and blood circulation is associated with the occurrence and development of cancer. The lncRNAs play an significant role in proliferation, differentiation, migration and apoptosis of the tumor cells. Explore the potential mechanism between lncRNAs and NSCLC is beneficial for the early diagnosis, target therpy and improve prognosis. Therefore, the study aims to demonstrate the latest studies on the lncRNAs related to occurence, diagnosis, therpy and prognosis of NSCLC. It can help to deeply understanding of lncRNA, and provide new ideas for the prevention of NSCLC.
