Objective:To analyze the usage intention and key issues of medical staff to use telemedicine, for improving telemedicine service system in China.Methods:From October to November 2019, medical workers of both the inviting party and invited party who experienced telemedicine in seven provinces of Fujian, Hainan, Henan, Hunan, Guizhou, Sichuan and Qinghai were selected for an online questionnaire survey. Areas covered included their usage intention, satisfaction and cognitive appraisal of telemedicine. Descriptive statistical analysis and non-parametric test were used to discuss the intention of further use, satisfaction and challenges of medical workers in various provinces and regions.Results:1 084 valid questionnaires were recovered. The data found the overall satisfaction was 98.62%, and the proportion of their intention of further use was 98.25%, and those from the eastern and western provinces presented higher intention of usage. The top challenges as reflected by these medical workers were named as follows: timeliness of consultation progress and information feedback; long latency time; low Internet speed, poor and interrupted Internet signal; inadequate system equipments and inconvenient operation; difficulties in remote physical checkup and overall understanding of patient conditions; as well as substandard, incomplete and poor medical records.Conclusions:These medical workers are satisfied with the telemedicine services and willing to continue to use telemedicine.For those existing problems, it is suggested to strengthen the infrastructure and optimize the process of telemedicine services, so as to encourage them in greater use of telemedicine.

Objective:To analyze the actual and expected incentives and key issues of telemedicine providers in China and to provide important references for optimizing telemedicine incentive policies.Methods:The sample data came from a questionnaire survey of 1 084 providers in 7 provinces of Fujian, Hainan, Henan, Hunan, Guizhou, Sichuan and Qinghai in October and November 2019 and a semi-structured interview data at 6 hospitals in Henan province in January 2020. Descriptive analysis was used to sort such data into text data for classified summation.Results:The greatest gaps were found between actual incentives and expected ones in expense subsidies, title promotion and excellence awards, with such gaps as high as 18.65, 28.26, 29.28 percentages among providers of junior, deputy senior and senior academic titles respectively. Hospitals fall short in providing adequate incentives for telemedicine providers, not to mention lack of differentiation and diversification in personnel incentives, and poor implementation of incentive policies.Conclusions:It is suggested to strengthen incentive demand analysis, break the homogenization bottleneck of incentive policies, and consolidate internal publicity and implementation of incentive policies.

Background/Aims: To evaluate temporal trends of atrial fibrillation (AF) prevalence in critically ill patients who received prolonged mechanical ventilation (MV) in the United States. Methods: We used the 2008 to 2014 National Inpatient Sample to compute the weighted prevalence of AF among hospitalized adult patients on prolonged MV. We used multivariable-adjusted models to evaluate the association of AF with clinical factors, in-hospital mortality, hospitalization cost, and length of stay (LOS). Results: We identified 2,578,165 patients who received prolonged MV (21.27% of AF patients). The prevalence of AF increased from 14.63% in 2008 to 24.43% in 2014 (p for trend < 0.0001). Amongst different phenotypes of critically ill patients, the prevalence of AF increased in patients with severe sepsis, asthma exacerbation, congestive heart failure exacerbation, acute stroke, and cardiac arrest. Older age, male sex, white race, medicare access, higher income, urban teaching hospital setting, and Western region were associated with a higher prevalence of AF. AF in critical illness was a risk factor for in-hospital death (odds ratio, 1.13; 95% confidence interval, 1.11 to 1.15), but in-hospital mortality in critically ill patients with AF decreased from 11.6% to 8.3%. AF was linked to prolonged LOS (2%, p < 0.0001) and high hospitalization cost (4%, p < 0.0001). LOS (–1%, p < 0.0001) and hospitalization cost (–4%, p < 0.0001) decreased yearly. Conclusions The prevalence of comorbid AF is increasing, particularly in older patients. AF may lead to poorer prognosis, and high-quality intensive care is imperative for this population.

OBJECTIVETo investigate the differences in dielectric properties (relative permittivity and conductivity) between the mucosal surface and serosal surface of malignant colorectal tissues, adjacent tissues at 1 cm and 3 cm from the tumor focus and normal colorectal tissues.

METHODSThe dielectric properties of the mucosal and serosal surface of malignant colorectal tissues, adjacent tissues (1 cm and 3 cm) and normal colorectal tissues from 39 patients with colorectal cancer were measured with an open-ended coaxial probe within the frequency range of 50 MHz-3 GHz, and the corresponding dielectric properties were analyzed respectively; statistical tests of the data were used to analyze the dielectric properties at 6 specific frequency points.

RESULTSThe dielectric properties were significantly higher in the malignant mucosa surface than in the adjacent tissues and normal colorectal tissues at the 6 specific frequency points (P<0.01). The dielectric properties decreased progressively in adjacent tissues at 1 cm and 3 cm and normal mucosa surface. The mucosal and serosal surface of malignant tissues showed significant differences in dielectric properties at 64 MHz, 128 MHz, 298 MHz, 433 MHz, and 915 MHz (P<0.01) but not at 2450 MHz (P>0.01), but such differences were not observed in normal tissues (P>0.01).

CONCLUSIONThe dielectric properties of the mucosal surface of the mucosal decrease in the order of malignant colorectal tissue, adjacent tissues at 1 cm and 3 cm from the tumor foci and normal colorectal tissues. The dielectric properties are higher in the mucosal surface than in the serosal surface in the malignant tissue, but comparable in normal colorectal tissues.

Objective: To investigate the molecular characteristics of ciprofloxacin-cefotaxime-azithromycin co-resistant Salmonella enterica serovar Thompson (S. Thompson) isolates from sporadic cases of foodborne diseases and aquatic foods in Hunan province. Methods: Ciprofloxacin-cefotaxime-azithromycin co-resistant S. Thompson isolates were selected from samples, and broth microdilution method was used to determine the resistance to 11 antibiotics of these isolates in vitro. Whole genome sequencing was used for investigating antimicrobial resistance gene patterns and phylogenetic relationships of strains. Results: Nine ciprofloxacin-cefotaxime-azithromycin co-resistant isolates were recovered from 19 S. Thompson isolates. Among nine ciprofloxacin-cefotaxime-azithromycin co-resistant isolates, eight of them harbored IncC plasmids, simultaneously carrying plasmid-mediated quinolone resistance (PMQR) genes qepA and qnrS1, β-lactamase resistance gene bla_CMY-2, azithromycin resistance gene mph(A), and one isolate harbored IncR plasmid, and carried PMQR genes qnrB4 and aac(6')-Ib-cr, bla_OXA-10 and mph(A). Genetic environment analysis showed that qnrS1, qepA, mph(A) and bla_CMY-2 genes might be integrated on genomes of strains by ISKra4, IS91, IS6100 and ISEcp1, respectively. Phylogenetic core genome comparisons demonstrated that ciprofloxacin-cefotaxime-azithromycin co-resistant isolates from patients and aquatic foods were genetically similar and clustered together. Conclusion: Ciprofloxacin-cefotaxime-azithromycin co-resistant S. Thompson isolates have been isolated from both human and aquatic food samples, suggesting that the spread of multidrug resistant Salmonella between human and aquatic animals.

Aim To observe the effect of epimedium on the proliferation and stem cell-like character expression of breast cancer cells, and investigate the relationship between the inhibition of stem cell-like character and miR-148a by epimedium, and its molecular mechanism. Methods After treatment with different concentrations of epimedium, cell viability and population dependence were detected by MTT assay and colony formation assay; the breast cancer stem cell-derived mammosphere formation was examined by Mammosphere assay; the expression levels of CD44,ALDH-1, Oct4,BMIl and EpCAM were detected by qPCR; the protein expression levels of EpCAM, SOX4, ZO-1, E-cadherin and vimentin were detected by Western blot; the protein localization of EpCAM was observed by im-munofluorescence assay; the effect of epimedium on migration was detected by wound healing assay. The miR-148a mimic was transfected into MDA-MB-231 cells, and the effects of epimedium on stem-like character expression of transfected MDA-MB-231 cells were observed. Results Epimedium significantly inhibited the proliferation and population dependence of MDA-MB-231 cells (P < 0.05 ), and reduced the breast cancer stem cell-derived mammosphere formation; compared with control group, epimedium significantly decreased mRNA levels of CD44, ALDH-1, Oct4, BMI1 and EpCAM (P <0.05) ,decreased protein contents of EpCAM, SOX4 and Vimentin (P < 0.05 ), up-regulated the protein expression of ZO-1 and e-cadherin ( P <0.05) ,and decreased the migration ability of MDA-MB-231 cells (P < 0.05). Epimedium up-regulated the expression of miR-148a in MDA-MB-231 cells (P <0.01). YYH + miR-148a mimic group significantly inhibited stem-like character expression and EMT process of breast cancer MDA-MB-231 cells compared with control group (P <0.05). Conclusions Epimedium can inhibit the proliferation of MDA-MB-231 cells, which may be related to the up-regulation of miR-148a, decrease of stem-like character expression of breast cancer cells,and inhibition of EMT.

OBJECTIVETo evaluate the effects of wrist-ankle acupuncture combined with ginger moxibustion against gastrointestinal tract reactions (nausea, vomiting, and constipation) to chemotherapy in cancer patients.

METHODSA total of 60 patients with gynecological tumors treated by chemotherapy were randomly divided into two groups. The treatment group (30 cases) underwent wrist-ankle acupuncture and ginger moxibustion, whereas tropisetron hydrochloride and dexamethasone were intravenously administered to the control group (30 cases) during chemotherapy.

RESULTSThe frequency of nausea in the treatment group was significantly less than that of the control group from the 2nd to the 5th day of chemotherapy (P<0.01). The anti-emetic effect in the treatment group was significantly better than that in the control group on the 3rd day of therapy (P<0.05). The incidence rate of constipation was significantly lower in the treatment group than that in the control group (P<0.01). Furthermore, the cost of therapy for the treatment group was significantly lower than that of the control group (P<0.01). Only 1 patient manifested a post-acupuncture side effect in the form of subcutaneous blood stasis.

CONCLUSIONWrist-ankle acupuncture combined with ginger moxibustion could prevent gastrointestinal tract reactions to chemotherapy in cancer patients. In addition, the proposed method had fewer side effects, lower cost, and less risk.

BACKGROUND: Delivery room resuscitation assists preterm infants, especially extremely preterm infants (EPI) and extremely low birth weight infants (ELBWI), in breathing support, while it potentially exerts a negative impact on the lungs and outcomes of preterm infants. This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China. METHODS: The clinical data of EPI (gestational age [GA] <28 weeks) and ELBWI (birth weight [BW] <1000 g), admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018, were analyzed. The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation (DRI). The secondary outcomes were survival rates, incidence of bronchopulmonary dysplasia (BPD), and risk factors for BPD. RESULTS: A cohort of 952 preterm infants were enrolled. The incidence of DRI, chest compressions, and administration of epinephrine was 55.9% (532/952), 12.5% (119/952), and 7.0% (67/952), respectively. Multivariate analysis revealed that the risk factors for DRI were GA <28 weeks (odds ratio [OR], 3.147; 95% confidence interval [CI], 2.082-4.755), BW <1000 g (OR, 2.240; 95% CI, 1.606-3.125), and antepartum infection (OR, 1.429; 95% CI, 1.044-1.956). The survival rate was 65.9% (627/952) and was dependent on GA. The rate of BPD was 29.3% (181/627). Multivariate analysis showed that the risk factors for BPD were male (OR, 1.603; 95% CI, 1.061-2.424), DRI (OR, 2.094; 95% CI, 1.328-3.303), respiratory distress syndrome exposed to ≥2 doses of pulmonary surfactants (PS; OR, 2.700; 95% CI, 1.679-4.343), and mechanical ventilation ≥7 days (OR, 4.358; 95% CI, 2.777-6.837). However, a larger BW (OR, 0.998; 95% CI, 0.996-0.999), antenatal steroid (OR, 0.577; 95% CI, 0.379-0.880), and PS use in the delivery room (OR, 0.273; 95% CI, 0.160-0.467) were preventive factors for BPD (all P < 0.05). CONCLUSION Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.
