Thanks to the transmission characteristics of 2019 novel coronavirus pneumonia, Internet-based hospitals can effectively cut off the transmission route via online consulting service. The hospital, leveraging the UTAUT model and DST theory, and advantages of Internet-based hospitals, is deploying step by step such four modules, as "pre-hospital screening", "patient acceptance", "auxiliary diagnosis and treatment", and "prevention and control linkage". These efforts ultimately contribute to an innovative prevention and control pattern against the novel coronary pneumonia for Internet-based hospitals and based on the UTAUT-DST model. This practice proves an initial success, and offers useful references for prevention and control of the NCP and development of other Internet-based hospitals.

The differences of transitional components and metabolic processes of Huatan Jiangqi Capsules(HTJQ) in rats under normal physiological and pathological conditions of COPD were analyzed by UPLC-Q-TOF-MS. The rat COPD model was established by passive smoking and intratracheal instillation of lipopolysaccharide. After the normal and COPD model rats were douched with HTJQ, the blood was collected from hepatic portal vein and the drug-containing serum samples were prepared by methanol precipitation of protein. Then, 10 batches of drug-containing serum samples of HTJQ were prepared and analyzed by UPLC serum fingerprint to evaluate the quality and stability of drug-containing serum samples. UPLC-Q-TOF-MS was used to collect the mass spectrometric information of the transitional components. Twenty-eight transitional components of HTJQ in normal rats and 25 transitional components of HTJQ in COPD model rats were identified by UPLC-Q-TOF-MS. Under pathological and physiological conditions, there were not only the same transitional components in rat serum, but also corresponding differences. Further studies showed that there were also differences in the metabolic process of transitional components between the two conditions. In normal rats, most of the metabolic types of transitional components were phase I reactions. In COPD model rats, phase Ⅰ reactions decreased and phase Ⅱ reactions increased correspondingly. With UPLC-Q-TOF-MS technology, the differences of transitional components and the metabolism process of HTJQ in rats under normal physiological and pathological conditions were analyzed. The results showed that types of transitional components and the activity of some metabolic enzymes would be changed in COPD pathological state, which would affect the metabolic process of bioactive components in vivo. It laid a foundation for further elucidating the metabolic process and pharmacodynamic substance basis of HTJQ.

OBJECTIVE: To investigate the clinical features and outcome of neonatal acute respiratory distress syndrome (ARDS) in southwest Hubei, China. METHODS: According to the Montreux definition of neonatal ARDS, a retrospective clinical epidemiological investigation was performed on the medical data of neonates with ARDS who were admitted to Department of Neonatology/Pediatrics in 17 level 2 or level 3 hospitals in southwest Hubei from January to December, 2017. RESULTS: A total of 7 150 neonates were admitted to the 17 hospitals in southwest Hubei during 2017 and 66 (0.92%) were diagnosed with ARDS. Among the 66 neonates with ARDS, 23 (35%) had mild ARDS, 28 (42%) had moderate ARDS, and 15 (23%) had severe ARDS. The main primary diseases for neonatal ARDS were perinatal asphyxia in 23 neonates (35%), pneumonia in 18 neonates (27%), sepsis in 12 neonates (18%), and meconium aspiration syndrome in 10 neonates (15%). Among the 66 neonates with ARDS, 10 neonates (15%) were born to the mothers with an age of ≥35 years, 30 neonates (45%) suffered from intrauterine distress, 32 neonates (49%) had a 1-minute Apgar score of 0 to 7 points, 24 neonates (36%) had abnormal fetal heart monitoring results, and 21 neonates (32%) experienced meconium staining of amniotic fluid. Intraventricular hemorrhage was the most common comorbidity (12 neonates), followed by neonatal shock (9 neonates) and patent ductus arteriosus (8 neonates). All 66 neonates with ARDS were treated with mechanical ventilation in addition to the treatment for primary diseases. Among the 66 neonates with ARDS, 10 died, with a mortality rate of 15% (10/66), and 56 neonates were improved or cured, with a survival rate of 85% (56/66). CONCLUSIONS Neonatal ARDS in southwest Hubei is mostly mild or moderate. Perinatal asphyxia and infection may be the main causes of neonatal ARDS in this area. Intraventricular hemorrhage is the most common comorbidity. Neonates with ARDS tend to have a high survival rate after multimodality treatment.

BACKGROUND: An artificial intelligence system of Faster Region-based Convolutional Neural Network (Faster R-CNN) is newly developed for the diagnosis of metastatic lymph node (LN) in rectal cancer patients. The primary objective of this study was to comprehensively verify its accuracy in clinical use. METHODS: Four hundred fourteen patients with rectal cancer discharged between January 2013 and March 2015 were collected from 6 clinical centers, and the magnetic resonance imaging data for pelvic metastatic LNs of each patient was identified by Faster R-CNN. Faster R-CNN based diagnoses were compared with radiologist based diagnoses and pathologist based diagnoses for methodological verification, using correlation analyses and consistency check. For clinical verification, the patients were retrospectively followed up by telephone for 36 months, with post-operative recurrence of rectal cancer as a clinical outcome; recurrence-free survivals of the patients were compared among different diagnostic groups, by methods of Kaplan-Meier and Cox hazards regression model. RESULTS: Significant correlations were observed between any 2 factors among the numbers of metastatic LNs separately diagnosed by radiologists, Faster R-CNN and pathologists, as evidenced by rradiologist-Faster R-CNN of 0.912, rPathologist-radiologist of 0.134, and rPathologist-Faster R-CNN of 0.448 respectively. The value of kappa coefficient in N staging between Faster R-CNN and pathologists was 0.573, and this value between radiologists and pathologists was 0.473. The 3 groups of Faster R-CNN, radiologists and pathologists showed no significant differences in the recurrence-free survival time for stage N0 and N1 patients, but significant differences were found for stage N2 patients. CONCLUSION: Faster R-CNN surpasses radiologists in the evaluation of pelvic metastatic LNs of rectal cancer, but is not on par with pathologists.

Objective: To evaluate the scale, efficiency and quality of secondary and tertiary public hospitals in Anhui province, and analyze the degree of coupling and coordination among the three dimensions. Methods: Thirty-two hospitals′ data were extracted from the direct reporting system of Anhui Health Commission. Hospital efficiency was evaluated by DEA model, hospital quality was evaluated by TOPSIS model, and coupling coordination degree was analyzed by coupling function. Results: In the single-dimension evaluation, there were significant differences in the distribution of the three dimensions among different levels of hospitals, and the efficiency and quality of secondary hospitals were better than those of tertiary hospitals. In the coupling evaluation, the average degree of coupling coordination in Anhui was 0.637, which was in the " primary coordination" level. The overall coupling and coordination degree of the tertiary hospitals were better than that of the secondary hospitals, and the highest score was in central Anhui. Conclusions Single-dimensional evaluation method cannot objectively represent a general picture of the hospitals. On the other hand, coupling coordination degree evaluation can provide a more comprehensive and objective result. The development strategy of hospitals should be made to fit local conditions and to coordinate the development of scale, efficiency and quality.
