RESUMO
Objective:To find the preferences of nursing staff when they provide " Internet + nursing service" for elderly patients.Methods:By means of the discrete choice experiment, a questionnaire was designed to investigate the preferences of nursing staff when they provide " Internet + nursing services" for elderly patients. In-service nursing staff from 8 medical and health institutions in Ningbo city and Wenzhou city were selected by random sampling, for an online questionnaire survey conducted from May to June 2022. The preferences of nursing staff on their service income, service content, service distance, service continuity and residence status of elderly patients when providing " Internet + nursing service" were analyzed by mixed logit regression.Results:A total of 420 valid questionnaires were collected. Compared to 50 yuan/order, nursing staff preferred to a price of 150 yuan/order ( β= 1.22, P<0.001) nursing services; Compared to specialized nursing services, nursing staff preferred to the routine care ( β= 0.86, P<0.001) and health promotion ( β= 0.86, P<0.05) service; Compared to<5 km, nursing staff were unwilling to provide nursing services for elderly patients at distances of 5-10 km and 11-15 km ( β=-0.66, P<0.05; β=-0.95, P<0.001) ; Compared to 1-2 visits per month, nursing staff preferred not to provide continuing care services ( β=-0.70, P<0.05); Compared to homestay with the patient family, nursing staff preferred to provide nursing services for elderly patients residing in nursing homes ( β= 1.21, P<0.001) . Conclusions:Considering the preference of nursing staff tend to provide " Internet + nursing service" for the elderly patients with services featuring appropriate price, non-specialist care, close distance, low continuity (moderate intensity used as the reference) and security assurance for practice.
RESUMO
Objective:To establish a model C-GALAD for detecting hepatocellular carcinoma (HCC) from the chronic liver disease and healthy people based on the serum markers.Methods:A clinical cohort including 229 hepatocellular carcinoma patients, 2 317 patients with chronic liver disease and 982 healthy people, was retrospectively collected from eight hospitals or physical examination institutions from April 2018 to October 2020. The data were divided into a training set and a testing set by stratified sampling with a 6∶4 ratio. A predictive model was established on the training set using a logistic backward regression method and validated on the testing set. In addition, clinical data from March to July 2021 in Beijing You′ an Hospital affiliated to Capital Medical University, including 84 patients with liver cancer and 204 patients with chronic liver disease collected were used for external independent validation of the model. The receiver operating characteristic curve (ROC) area under curve (AUC), the sensitivity and the specificity were used to evaluate the effectiveness of the model.Results:Through the logistic backward regression method, the seven signatures including age, gender, alpha-fetoprotein (AFP), alpha-fetoprotein alloplasm-3 ratio (AFP-L3%), des-gamma-carboxyprothrombin(DCP), platelet (PLT) and total bilirubin (TBIL) were selected as risk factors in the detection model. The area under the ROC curve (AUC) of the model on the testing set was 0.954, with an 88.04% sensitivity and a 94.85% specificity, and the AUC of model on the external independent validation set was 0.943, with an 89.29% sensitivity and a 90.2% specificity, which were better than other published models.Conclusion:The C-GALAD Ⅱ model can accurately predict the risk of hepatocellular carcinoma occurrence, and thus provide a trustworthy diagnosis method of hepatocellular carcinoma.
RESUMO
Objective:To investigate the therapeutic efficacy and mechanisms of transcutaneous electrical acupoint stimulation (TEAS) in the treatment of postprandial distress syndrome (PDS) in functional dyspepsia (FD).Methods:A double-blinded, randomized, controlled study was conducted. At Sir Run Run Shaw Hospital, Medical School Zhejiang University 40 patients aged 18-70 years old who met the Rome Ⅳ diagnostic criteria of PDS were prospectively enrolled. After informed consent, the patients were randomly assigned to TEAS group or sham-TEAS group. The patients in the TEAS group received transcutaneous electrical acupoint stimulation at acupoints Zusanli and Neiguan, and those in the sham-TEAS group underwent stimulation at other mimic acupoints for four weeks. The symptoms, gastric accommodation (initial satiety volume (ISV) and maximum tolerable volume (MTV), time of half gastric emptying of solid food ( T1/2) and heart rate variability (high frequency, low frequency and ratio of low frequency to high frequency) were compared between the two groups before and after treatment. The expression levels of inflammatory cytokines in duodenal mucosa were also evaluated by polymerase chain reaction in PDS patients and 24 healthy volunteers. Independent sample t test, Mann-Whitney U test and chi square test were used for statistical analysis. Results:A total of 26 PDS patients were enrolled in the study, 13 cases each in the TEAS group and sham-TEAS group. Between the patients of the two groups, there were no statistically significant differences in gender, age, or score of 36-item short form health survey (SF-36), score of self-rating anxiety scale (SAS), score of self-rating depression scale (SDS), score of dyspeptic symptom severity index (DSSI), ISV, MTV, T1/2 or heart rate variability indexes (high frequency, low frequency and ratio of low frequency to high frequency) before treatment (all P>0.05). After treatment, the DSSI score of TEAS group was lower than that of sham-TEAS group (13.5±5.3 vs. 19.9±9.3), the values of ISV and MTV were both higher than those of sham-TEAS group ((180.0±44.6) mL vs. (121.9±61.0) mL, (480.4±200.7) mL vs. (338.5±108.8) mL), and the differences were all statistically significant ( t=2.18, 2.77 and 2.24, all P<0.05). After treatment there was no statistically significant difference in T1/2 between TEAS group and sham-TEAS group ( P>0.05). There was no statistically significant difference in T1/2 between before and after treatment in patients of TEAS group ( P>0.05). After treatment, the high frequency increased (5.3±1.2 vs. 4.0±0.9) and the ratio of low frequency to high frequency decreased (1.0±0.2 vs. 1.3±0.2), and the differences were statistically significant ( t=-3.31 and 3.73, both P<0.01). The expression levels of interleukin 6 (IL-6) mRNA in mucosa of duodenal bulb and descending duodenum of PDS patients were both higher than that of healthy control group (0.68, 0.11 to 6.74 vs. 0.03, 0.02 to 0.25; 6.46, 1.35 to 12.62 vs. 0.86, 0.32 to 2.90), and the differences were statistically significant ( Z=-2.24 and -2.03, P=0.02 and 0.04). After TEAS treatment for four weeks, the expression of IL-6 mRNA in duodenal bulb mucosa decreased compared with that before treatment in TEAS group (0.04, 0.01 to 0.06 vs. 0.23, 0.09 to 3.66) and the difference was statistically significant ( Z=-2.07, P=0.04). Conclusions:TEAS can improve the gastric accommodation and dyspeptic symptoms in PDS patients. The mechanism may be related with the vagal pathway mediating and regnlating the expression of inflammatory cytokine IL-6 in duodenal bulb mucosa.
RESUMO

RESUMO
Berberine (BBR) is known as a classic drug for intestinal infection treatment.BBR inhibits intestinal bacteria,which is the core of its role in the treatment of intestinal infection.With the survival of local intestinal bacteria and its related metabolites on the physiological and pathological functions of the body continue to recognize the impact of it,more and more literatures have presented the effect of BBR through the impact of intestinal bacteria on the body glycol-lipid metabolism,even brain function.This allows us to re-understand the pathophysiology of BBR in inhibiting gut microbiome.In this paper,the antibacterial activity of BBR was reviewed and analyzed.The possible molecular target of BBR was analyzed according to the characteristics of prokaryotes gene expression,which was helpful to the in-depth study of BBR on intestinal bacteria.Thus,a more comprehensive understanding of the pharmacological effects of BBR is given.
RESUMO
There have been many reports on berberine (BBR) effect of the inhibition on gut bacteria,but more from the protein level.In view of the preference of BBR for DNA binding,we here investigated the expression of BBR from the transcriptional expression level of the gene.The results showed that BBR had a higher affinity for UP element of Escherichia coli (E.coli) gene,and the transcription initiation region of this element contained TATA base sequence.The expression of genes sulA,recA and 16S which contain the genes of the UP element regulatory elements in the upstream of the promoter could be suppressed by BBR,and the expression of lpxC,secG and mutT which did not contain the genes of the UP element regulatory elements in the upstream of the promoter could not be inhibited by BBR.It is shown that the TATA sequence is the target of BBR.This result provides a new perspective for exploring the effect of BBR's inhibition of microbiota from gene transcription.

HPLC method can accurately detect the content of p-coumaric acid and ananasate of pineapple leave. There are different contents of p-coumaric acid and ananasate of pineapple leave in different origins. In Y unnan province, the contents of p-coumaric acid and ananasate of pineapple leave are the highest; while the contents of p-coumaric acid and ananasate in Guangxi province are the lowest. It was concluded that ananasate can be used in the quality identification. The p-coumaric acid and ananasate can be used in the quantitative determination in the better control of the quality of pineapple leaf.
RESUMO
This article was aimed to study the general reproductive toxicity in mice in order to give a better evalua-tion of the medicinal plant of pineapple leaves (A nanas comasus L). Adult male and female mice were orally admin-istered with pineapple leaves. And then, each of the male and female mice was put together in one cage for mating. The mating success females were fed continuously. The experimental observation was conducted in pregnancy, fetal development, as well as the offspring of mice. The results showed that in addition to a large dose of pineapple leaves (4 g·kg-1) of the parental male rats having a lower body weight, pineapple leaves did not significantly affect on other parameters. There were no significant effects on pregnant mice and their offspring of mice. It was concluded that the pineapple leaves did not influence the general reproductive function of mice apparently.
RESUMO
This article was aimed to study the antioxidant and antihyperlipidemic effect of total phenolic composition prepared from pineapple (A nanas comosus L.) leave. It had a rapid absorption after intragastric administration and the principle ingredient, p-coumaric acid, reached the peak concentration after 5 minutes of administration. The mice model with single intragastric administration of lipid and glucose were used in the observation of changes on postprandial glucose, lipid and intestinal lipase at different time points after drug administration. The results showed that phenols of pineapple leave can inhibit triglyceride and glucose absorption in certain extent. No significant effect was observed on inhibition at 30 minutes after the phenol administration. However, the intestinal lipase activity was obviously inhibited in normal mice and the intestinal lipase activity decline caused by acute lipid consumption can be reversed. It was concluded that the phenols pineapple leave may inhibit the absorption of lipids with correlation to lipase activity. It had certain regulation effect on the high postprandial glucose and fat absorption.
RESUMO
Brazilein is one of the active ingredients of a Chinese medicine Caesalpinia sappan L. This study was aimed to test the vasodilator effect of brazilein on vascular smooth muscle cells in vitro from the perspective of molecular biology. The results showed that brazilein mainly acted through the influence of potassium ion channels, reducing membrane depolarization in order to affect the vessel relaxation. This effect can be influenced by blocking 5-HT receptor, and, simultaneously, correlating with the regulation of intracellular calcium ion concentration, affecting calmodulin and downregulating MLCP. In addition, the alterations of cAMP, PKA and PGI2 were involved in the pharmacological process of brazilein.
