Objective:To evaluate the effectiveness of oral-nasal oxygen supply mouth guard in painless gastroscopy for snoring patients.Methods:The snoring patients who underwent painless gastroscopy at two Endoscopy Centers of Shanghai East Hospital, Tongji University in July 2022 were randomly divided into the observation group (using oral-nasal oxygen supply mouth guard) and the control group (using ordinary nasal oxygen tube and mouth guard). Parameters such as the wearing time and the removal time of the mouth guard, lowest pulse oxygen saturation (SpO 2), incidence of hypoxemia, and the satisfaction of medical staff were compared between the two groups. Results:The wearing time of mouth guard was 11.63±0.84 seconds and the removal time was 5.33±0.76 seconds in the observation group ( n=40), which were lower than those in the control group ( n=47) (14.91±1.21 seconds, t=-14.463, P<0.001; 10.38±0.80 seconds, t=-30.095, P<0.001). The wearing satisfaction score was 9.80±0.61, the lowest SpO 2 was (96.70±3.42)%, the removal satisfaction score was 9.75±0.67, and the anesthesiologists' satisfaction score was 9.20±1.42 in the observation group, which were higher than those in the control group [7.70±0.93, t=12.209, P<0.001; (94.06±3.72)%, t=3.417, P=0.001; 7.96±0.98, t=9.803, P<0.001; 8.13±1.35, t=3.615, P=0.001] with significant difference. There was no significant difference in the incidence of hypoxemia [10.00% (4/40) VS 14.89% (7/47), χ2=0.130, P=0.718] and endoscopic physician satisfaction score (9.30±0.97 VS 9.02±1.31, t=1.112, P=0.269) between the two groups. Conclusion:The oral-nasal oxygen supply mouth guard is easy to wear and remove, effectively reducing SpO 2 fluctuations during painless gastroscopy for snoring patients. It can enhance medical staff satisfaction with high clinical value.

Objective:To investigate the application of multiscale low-rank plus sparsity (MLRS) modeling in fast ultra-high-field intracranial 4D Flow imaging.Methods:Ten healthy volunteers, 5 males and 5 females, aged 23-35 (29±4) years old, recruited from October 2022 to January 2023 at Huashan Hospital of Fudan University, were prospectively collected. A MLRS model acceleration algorithm was proposed according to the characteristics of 4D Flow data based on the multiscale low-rank (MLR) model. Firstly, full sampling brain 4D Flow scans were performed on healthy volunteers using 7.0 T MR, and the acquired data were under-sampled with Gaussian distributions at different acceleration rates (R of 4, 8, 12, and 16, respectively). The root mean square error (RMSE) and peak signal-to-noise ratio (PSNR) of the compressed sensing algorithm (CS), low-rank plus sparse algorithm (L+S), MLR, and MLRS model were calculated at different acceleration rates, with fully sampled data as reference. And the comparison of models was performed using the paired-samples t-test or Wilcoxon signed rank test. Pearson′s test was used to assess the correlation between hemodynamic parameters of the 4 algorithms and the fully sampled reference values at different acceleration rates, and the correlation coefficients were compared using Wilcoxon signed rank test. Results:The RMSE under the same acceleration rates was MLRS, MLR, L+S, and CS models in ascending order, and the RMSE of the MLRS model was significantly lower than that of the MLR, L+S, and CS models ( P<0.05); the PSNR was MLRS, MLR, L+S, and CS models in descending order, and the PSNR of the MLRS model was significantly higher than that of the MLR, L+S, and CS model ( P<0.05). The correlation coefficients between the blood flow velocity measured by the MLRS model and the reference value were significantly higher than those of the MLR, L+S, and CS models for different acceleration rates ( P<0.05). Conclusion:The proposed MLRS algorithm is capable of accelerating ultra-high-field 4D Flow MR imaging of the brain while guaranteeing the image quality, and the MLRS model has higher reconstruction accuracy compared with conventional acceleration models at the same acceleration rate.

ABSTRACT OBJECTIVE To investigate the current situation of pediatric pharmacist-managed clinic in China, and to provide reference for pediatric pharmacist-managed clinic construction and improvement. METHODS Domestic Children's hospitals, Women's & Children's Hospital, and general hospitals with pediatric unit were selected as the survey objects, questionnaires were distributed through the Wenjuanxing Application, and SPSS 26.0 was used to describe the data. The development of pediatric pharmacist-managed clinic, the qualification of visiting pharmacists, the situation of post training and training needs were analyzed. RESULTS A total of 101 valid questionnaires were collected. Pediatric pharmacist-managed clinics had been set up in 55(54.5%) hospitals, of which 35 were independent pharmacists' clinics, and most had well medical document and patient management processes. However, about 70% of hospitals did not charge registration fees, and more than half of hospitals had fewer than 5 patient-visits per day. 85.5% of the hospitals were visited by clinical pharmacists, and about half of them were senior clinical pharmacists with more than 10 years of working experience. But only 3.6% of visiting pharmacists had the right of specific prescription. In 101 hospitals relevant post training for pharmacists had been carried out in 36 hospitals, of which 25 hospitals had set up pharmacist-managed clinic. In addition to pharmaceutical expertise, more than 50% of pharmacists had a strong demand for the improvement of physician-patient communication and problem-solving ability, and 30%-40% of the demand was focused on the collection of medication history, psychological counseling ability, and case-based learning in the pharmacist-managed clinic. CONCLUSION At present, the domestic pediatric pharmacist-managed clinic shows a vigorous development trend, however, there are insufficient registration fees, visits, and post training. Appropriate service methods of pediatric pharmacist-managed clinic should be actively explored, and a pediatric specialized training system for should be well constructed to improve the competency.

Abstract OBJECTIVE To analyze the drug-drug interaction during the use and treatment of nirmatrelvir/ritonavir tablets in children, and to provide reference for rational drug use in clinical practice. METHODS All hospitalized pediatric patients with using nirmatrelvir/ritonavir tablets from December 23, 2022 to February 8, 2023 in Children's Hospital, Zhejiang University School of Medicine were collected. The use of nirmatrelvir/ritonavir was analyzed, and the combination drugs were classified. The potential clinical drug-drug interactions of nirmatrelvir/ritonavir were analyzed through micromedex drug interaction database and the severity was graded. RESULTS A total of 48 patients using nirmatrelvir/ritonavir tablets were collected, with a median age of 6.71 years old(87 d-17.75 years old). The usage departments were mainly in the departments of hematology, ICU, infectious disease, and general internal medicine, and the main underlying disease being tumors. The median fever-reducing time after medication was 3 d. Many drugs were combined during medication period. A total of 15 potential drug-drug interaction drugs of nirmatrelvir/ritonavir tablets were collected, and potential drug interaction with antifungals should be considered. CONCLUSION The department with more usage of nirmatrelvir/ritonavir tablets in children is hematology, and the main underlying disease is tumors. When nirmatrelvir/ritonavir tablets are used in combination with potential drug-drug interaction drugs, attention should be paid to monitoring the efficacy and adverse reactions.

To assess the positive predictive value (PPV) of extended noninvasive prenatal testing (NIPT-plus) for fetal chromosomal abnormalities. This retrospective research enrolled 511 cases of pregnant women with positive NIPT-plus results at the Obstetrics and Gynecology Hospital of Fudan University from May 2017 to January 2021. Karyotype analysis and chromosome microarray analysis (CMA) techniques was applied for verification. All cases were followed to determine their pregnancy outcome. The Chi-square test was used in PPV. 63 out of 511 refused prenatal diagnosis after counseling, 448 pregnant women with prenatal diagnosis showed that the PPVs of NIPT-plus test for fetal trisomy 21, 18 and 13 (T21, T18, T13), sex chromosome aneuploidy (SCAs) and chromosome microdeletion/microduplication syndrome (MMS) were 86.0% (92/107), 79.5% (35/44), 54.5% (12/22), 39.5% (75/190), and 41.7% (30/72), respectively. The results revealed that the PPV was higher among older pregnant women compared to young pregnant women (77.8% vs. 51.9%, P<0.01). With increasing maternal age, the PPV of NIPT-plus presented increasing trends for T21, T13, and composite PPV except for T18 or SCAs. In addition, the termination rates for confirmed SCAs fetal karyotypes 45, X; 47, XXX; 47, XXY and 47, XYY were 11/11, 3/15, 91.7% (22/24) and 1/14, respectively. NIPT-plus can safely and effectively detect fetal chromosomal abnormalities and can be extended to MMS screening, significantly reducing the proportion of interventional prenatal diagnoses, and those with positive screening still require further confirmation.

The health literacy refers to the ability of individuals to acquire and understand basic health information and services and use them to make the right decisions to maintain and promote their health. Health literacy data focusing on cancer prevention and control was limited in China. In order to understand the health literacy and awareness of cancer risk factors and the cancer screening, early diagnosis and treatment in Chinese urban residents and compare the effect of different stages of the cancer intervention, the Cancer Screening Program in Urban China (CanSPUC) program, supported by the National Key Public Health Program, conducted a survey on the health literacy of the cancer prevention and treatment among urban residents in 16 provinces nationwide from 2015 to 2017. Four subgroups were designed in this survey, including (1) general population who have never participated in any cancer screening programs at a community-level; (2) individuals who have previously attended the CanSPUC program for cancer risk assessment or screening intervention; (3) cancer patients who were receiving treatment in local hospitals; (4) a special group from employees of government and public institutions (non-health system), state-owned enterprises and private enterprises (to have better understand on the impact of socioeconomic factors). The self-designed questionnaire covered six parts, including basic information, consciousness of common risk factors to cancer, awareness of early detection, awareness of early diagnosis, awareness of early treatment, and the needs and approaches for knowledge of cancer prevention and treatment. A total of 32 257 individuals were included in the final analyses. This paper landscaped the overall design of the survey, including participants, domains of the instrument, quality control, basic characteristics of the included individuals. These descriptions are applicable to each individual report of the current special issue of "Health Literacy of Cancer Control in Urban China" and future reports, in which more detailed results are and will be reported. The findings of this survey could provide some useful implications for similar researches in the future.

Caspases are a group of structurally related cysteine proteases present in cytosol. One of their important common points is that the active sites contain cysteine and can specifically break the peptide bonds after the aspartic acid residues. Caspases are broadly divided into two groups based on their functions, including inflammatory Caspases and apoptotic Caspases. Inflammatory Caspases include Caspase-1, Caspase-4, Caspase-5, Caspase-11 and Caspase-12, which play important roles in the process of innate immune defense. Unlike inflammatory Caspases, apoptotic Caspases(2/3/6/7/8/910)initiate and execute an immunologically silent form of programmed cell death known as apoptosis. However, ongoing investigations have uncovered essential functions of Caspase-8 in the regulation of immunity in cells and organisms. Accumulated studies have shown that Caspases play important roles in the occurrence and development of various immunity-related diseases. In order to comprehensively elucidate the relationship between Caspases and innate immunity, and to provide some scientific basis and theoretical reference for the treatment of various diseases, this article reviews the regulation of activity and inflammation mechanism of innate immunity-related Caspase-1/4/5/11/8/12.
