This paper collected and sorted out the cross-cultural medical practice in the top 20 US hospitals in 2019-2020 through web surveys, and summarized the concepts, featured projects and models of cross-cultural medical services in American hospitals. Generally, hospitals in the US advocate the service concept of "patient-centered", provide full-process services before, during and after the treatment, involving appointments, accommodation, transportation, language translation, medical process management, etc., and attach great importance to the role of culture factors in medical treatment and cross-cultural medical education and training for employees. On this basis, it is proposed that Chinese medical institutions should focus on the following aspects in the development of foreign-related medical services: conform to international medical service concepts and standards, improve the cross-cultural medical competence of medical staff and other groups, explore cross-cultural medical service models with localized characteristics, and build the international image of the hospital with the construction of international environment.

Objective:To explore the distribution characteristics and antibiotic resistance of pathogen in children with hematological disorders and cancers complicated with sepsis in pediatric intensive care unit (PICU).Methods:The clinical data of children with hematological disorders and cancers complicated with sepsis hospitalized at Shenzhen Children′s Hospital affiliated to China Medical University from January 2016 to August 2023 were retrospectively analyzed. Patients were divided into survival group and death group based on the outcome of sepsis on 28 days after diagnosis.Results:A total of 202 sepsis episodes occurred in 176 children were enrolled in this study. Among all, 144 (71.3%) cases of bloodstream infection, 59 (29.2%) cases of pulmonary infection, 21 (10.4%) cases of abdominal infection, 9 (4.5%) cases of soft tissue infection, 9 (4.5%) cases of nervous system infection, and 3 (1.5%) cases of urinary tract infection. A total of 244 pathogenic strains were identified, in which 74 (30.3%) cases were gram-positive bacteria. The top 3 pathogens isolated were Coagulase negative Staphylococcus (21 strains), Staphylococcus aureus (19 strains) and Streptococcus pneumoniae (13 strains). Gram-negative bacteria accounted for 122 (50.0%) strains, in which top 3 were Klebsiella pneumonia (33 strains), Escherichia coli (25 strains), and Pseudomonas aeruginosa (23 strains). Fungi comprised 48 (19.7%) strains:the top 3 were Candida tropicalis (14 strains), Candida albicans (10 strains), Aspergillus and Pneumocystis jirovecii (7 strains each). The incidence of Acinetobacter baumannii, Stenotrophomonas maltophilia, and Pseudomonas aeruginosa were significantly higher in death group compared to survival group[9.0%（6/67）vs. 2.3%（4/177）, χ2＝3.971 ，P＝0.046; 9.0%（6/67）vs. 1.1%（2/177）, χ2＝7.080 ，P＝0.008;16.4%（11/67）vs. 6.8%（12/177）, χ2＝5.288 ，P＝0.021]. The samples of 57 cases were simultaneously detected by both culture and metagenomic next-generation sequencing (mNGS). Pathogens were detected in 25 cases by both culture and mNGS. In 30 cases, pathogen detection were mNGS positive but culture negative. Two cases showed positive results only with culture. A total of 79 (46.8%) strains were multi-drug resistant bacteria, including 27 (34.2%) strains of gram-positive bacteria and 52 (65.8%) strains of gram-negative bacteria. A total of 174 (86.1%) children with sepsis received empirical anti-infective drugs within 24 hours of fever onset. A total of 124 (61.4%) cases were appropriately covered by the initial empirical antibiotics, while 40 (19.8%) cases were not adequately covered and 10 (5.0%) cases had incomplete coverage. Despite the inclusion of pathogenic in the coverage, resistance to initial antibiotics was observed in 22 (10.9%) cases. Fifty-one patients died. Conclusion:The predominant pathogens responsible for sepsis in PICU with hematological disorders and cancers is gram-negative bacteria, followed by gram-positive bacteria and fungi. In comparison to healthy children with sepsis, there is a higher incidence of fungal infections among hematological disorders and cancers. The proportion of multi-drug resistant bacteria infection is high. Early identification and combination of local etiological distribution and drug resistance, along with the empirical selection of appropriate anti-infection treatment strategies, can greatly enhance survival rate.

Psoraleae Fructus （PF） is a non-toxic Chinese herbal medicine， while the liver injury caused by PF has aroused wide concern in recent years. At present， animal experiments and in vitro studies have been carried out to explore the mechanism， targets， and toxic components of PF in inducing liver injury， which， however， have differences compared with the actual conditions in clinical practice， and there are still some potential hepatotoxic components and targets of PF that have not been discovered. With the continuous progress in systems biology， establishing the drug-induced liver injury model and the liver injury prediction model based on network toxicology can reduce the cost of animal experiments， improve the toxicity prediction efficiency， and provide new tools for predicting toxic components and targets. To systematically explain the characteristics of liver injury in the application of PF and explore the potential hepatotoxic components and targets of PF， we reviewed the related articles published by China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， and PubMed from 1962 to 2021 and analyzed the characteristics and influencing factors of liver injury caused by PF in the patients. Furthermore， we summarized the chemical components of PF and the components entering blood. By reviewing the mechanism， targets， and components of PF in inducing liver injury that were discovered by in vivo and in vitro experiments， we summarized the known compounds in PF that may cause liver injury. Finally， the current methods for building the prediction model of PF-induced liver injury were summarized， and the predicted toxic components and targets were introduced. The possible factors of PF in causing liver injury were explained from three aspects： clinical characteristics， preclinical studies， and computer-assisted network prediction， which provide a reference for predicting the risk of PF-induced liver injury.

【Objective】 To investigate the development of adaptability in children aged 2 - 6, and to explore its influencing factors, so as to provide reference for promoting the development of adaptability in young children. 【Methods】 Data were from the National Nutrition and Health Systematic Survey for Children in China, and 3 319 children aged 2 - 6 and their parents from 28 sites across 14 provinces were recruited in this study.The Development Scale for Children Aged 0 - 6 years (WS/T 580-2017) was used to measure the developmental quotient of children′s adaptive ability, and a survey questionnaire was used to collect relevant information about children and their parents. 【Results】 Among 3 319 children aged 2 - 6, the proportion of slightly low or low level of adaptability, moderate adaptability development, good and excellent adaptability development was 7.68%,66.25% and 26.06%, respectively.The proportion of children aged 5 - 6 with good and excellent adaptability was lower in 3-year-old and 4-year-old groups (χ²=59.29, P<0.05).Multiple stepwise linear regression showed that children′s gender (β=0.06), gestational age of birth (β=-0.05), only child (β=-0.04), left-behind child (β=-0.04), the main caregiver (β=-0.06), and the education level of parents (β=0.09, 0.10), whether parents actively pay attention to children′s emotions (β=-0.06) and whether children play with homemade toys (β=-0.04) were the influencing factors of children′s adaptive development quotient.Girls, full-term children, only children, non-left-behind children, children with parents as main caregivers, parents with a high level of education, parents who often take the initiative to pay attention to children′s emotions, and children who play with homemade toys had a higher level of adaptability development quotient. 【Conclusions】 The development level of adaptability in children aged 2 - 6 in China is mostly above the average level and is related to multiple factors.Targeted intervention work can be carried out on relevant factors in order to promote the development of children′s adaptability.

Objective:To investigate the diagnostic performance of CT-derived fractional flow reserve (CT-FFR) derived from standard images (STD), images processed by first-generation (SSF1) and second-generation (SSF2) whole-heart motion correction algorithm, respectively.Methods:Patients who underwent both coronary CT angiography (CCTA) and invasive coronary angiography (ICA) with FFR examination within 3 months in Shanghai General Hospital, Shanghai Jiao Tong Univerisity School of Medicine from January 2020 to December 2022 were screened in this retrospective study. Totally of 121 patients (134 lesions) were finally included in the study. CCTA images were reconstructed using iterative reconstruction, iterative reconstruction plus SSF1 and SSF2 algorithms. All images were divided into three groups: STD group, SSF1 group, and SSF2 group. The image quality of the CCTA images was assessed using the Likert scale, and differences between the two groups were compared using the Mann-Whitney U and Kruskal-Wallis test. The correlation and consistency between CT-FFR and FFR were evaluated using Spearman correlation coefficient and Bland-Altman plots. The diagnostic performance of CCTA and CT-FFR from three groups was compared by receiver operating characteristic (ROC) curves. The area under the curve (AUC) was compared using the DeLong test. Results:Compared to the STD group and SSF1 group, the SSF2 group showed the best performance in image quality score (median=3.7). Best correlation ( r=0.652, P<0.001) and consistency (mean difference=0.03) between CT-FFR and FFR were observed in SSF2 group. ROC analysis results revealed that, at the per-lesion level, in the diagnosis of ischemic lesions, the diagnostic performance of CT-FFR in the SSF2 group was significantly better than that of the SSF1 group (AUC=0.88 vs. 0.76, P=0.003), while no significant difference was observed between STD group and SSF1 group ( P=0.125). At the per-patient level, the SSF2 group also demonstrated the highest diagnostic performance. Conclusion:The SSF2 algorithm significantly improved CCTA image quality and enhanced its diagnostic performance for evaluating stenosis severity and CT-FFR calculations.

Objectives:To investigate the association between social determinants of health(SDOH)and incident stroke and analyze the main risk factors for stroke among resident with different SDOH levels. Methods:From 2012 to 2015,30 036 residents(≥35 years old)from 30 districts in 14 provincial-level administrative divisions in China were enrolled this study based on stratified multi-stage-random-sampling method.The prevalence of cardiovascular diseases and related risk factors were investigated,and stroke events were followed up in 2018 to 2019.Principal component analysis was performed to establish SDOH scores based on 9 indicators related to socioeconomic and healthcare resources,participants were divided into low SDOH group(n=8 343)when it was≥-2.01 to<-1.14,middle SDOH group(n=7 257)when it was≥-1.14 to<0.10,and high SDOH group(n=8 457)when it was≥0.10 to≤5.79.Multivariate Cox regression was applied to estimate the association of SDOH levels with incident stroke.The random survival forest method was used to analyze the major risk factors in different SDOH levels. Results:A total of 24 057 participants were finally included,669(2.8%)participants developed stroke during a mean of(4.7±0.8)years follow-up.The incidence densities of stroke in the low,medium,and high SDOH groups were 468.39,628.85,and 700.39/100 000 person-years,respectively(Pdifference<0.05,Ptrend=0.01).Compared with individuals with low SDOH level group,fully HR for incident stroke among those with medium and high were 1.91(95%CI:1.54-2.36)and 1.59(95%CI:1.30-1.95),respectively(Ptrend<0.001).Advanced age is the primary risk factor for stroke in the population,especially in districts with high SDOH level.In districts with medium SDOH level,diabetes is an important risk factor for stroke.High blood pressure and alcohol consumption are important modifiable risk factors in low SDOH level districts. Conclusions:Present study shows that higher levels of SDOH are associated with increased risk of stroke.The main risk factors for stroke differ among participants with different SDOH level districts.Targeted interventions should be implemented to improve the prevention and treatment of stroke in populations with different levels of SDOH.

Health security for rare diseases has aroused much attention in the society nowadays, In this article, we analyzed in-depth the construction of rare diseases health security in China by studying the literature reviews, expert interviews, and reports of pilot policy investigations. We conclude in the study that it is an important step to constructing a multiple health security system for the rare disease making the basic health security as the cornerstone. For rare medications and treatments that cannot be covered by the current national health insurance, it is necessary to build an specific funding for rare disease funding as a means of safeguard. Finally, for those who are financially disadvantages, the system should involve relief and philanthropy to help them. By constructing a multiple health security system, rare diseases patients in our country will get a well-covered health care.

Objective:To evaluate the efficacy of combining modified manipulative reduction with functional training for the treatment of acute anterior disc displacement without reduction.Methods:Sixty anterior disc displacement patients aged from 19 to 55 years were randomly divided into an experimental group and a control group, each of 30. The experimental group was given modified manipulative reduction, while the control group was provided with traditional manipulative reduction. After the manipulative reduction, both groups received 3 months of functional training. Visual analog scale (VAS) ratings, maximum active mouth opening, a mandibular movement index and magnetic resonance imaging (MRI) were employed before and immediately after the reduction and after the functional training to evaluate their effectiveness. An oral health-related quality of life scale was also used. The number of attempts needed to achieve successful reduction and the overall success rate were compared between the two groups.Results:There was significant improvement in the average VAS ratings, maximum active mouth opening, mandibular movement index and oral health-related life quality of both groups after the experiment. Immediately after reduction, the maximum active mouth opening and mandible movement in the experimental group were significantly higher than in the control group, on average. Further improvement was observed after the treatment such that there was no significant difference between the two groups. After the functional training, however, the experimental group′s average VAS and oral health-related life quality scores were significantly better than the control group′s averages. According to MRI right after reduction, the success rate of the experimental group (96.7%) was significantly better than among the control group (80%). After the functional training the corresponding values were 86.7% and 73.3%. That difference was no longer significant. There was also no significant difference in the number of attempts needed to achieve successful reduction.Conclusion:The modified manipulative reduction not only has a higher success rate, but also can immediately improve mouth opening and mandible mobility. Combined with functional training, it can effectively reduce pain and improve life quality.
