ObjectiveTo understand the infection characteristics of multidrug-resistant organisms (MDROs) in hospitalized patients in a tertiary sentinel hospital in Shanghai, so as to provide an evidence for the development of targeted prevention and control measures. MethodsData of MDROs strains and corresponding medical records of some hospitalized patients in a hospital in Shanghai from 2021 to 2023 were collected, together with an analysis of the basic information, clinical treatment, underlying diseases and sources of sample collection. ResultsA total of 134 strains of MDROs isolated from hospitalized patients in this hospital were collected from 2021 to 2023 , including 63 strains of methicillin-resistant Staphylococcus aureus (MRSA), 57 strains of carbapenem-resistant Acinetobacter baumannii (CRAB), and 14 strains of carbapenem-resistant Klebsiella pneumoniae (CRKP). Of the 134 strains, 30 strains were found in 2021, 47 strains in 2022 and 57 strains in 2023. The male-to-female ratio of patients was 2.05∶1, with the highest percentage (70.90%) in the age group of 60‒<90 years. The primary diagnosis was mainly respiratory disease, with lung and respiratory tract as the cheif infection sites. There was no statistically significant difference in the distribution of strains between different genders and infection sites (P>0.05). However, the differences in the distribution of strains between different ages and primary diagnosis were statistically significant (P<0.05). Patients who were admitted to the intensive care unit (ICU), had urinary tract intubation, were not artery or vein intubated, were not on a ventilator, were not using immunosuppresants or hormones, and were not applying radiotherapy or chemotherapy were in the majority. There was no statistically significant difference in the distribution of strains for whether received radiotherapy or chemotherapy or not (P>0.05), while the differences in the distribution of strains with ICU admission history, urinary tract intubation, artery or vein intubation, ventilator use, and immunosuppresants or hormones use or not were statistically significant (all P<0.05). The type of specimen was mainly sputum, the hospitalized ward was mainly comprehensive ICU, the sampling time was mainly in the first quarter throughout the year, the number of underlying diseases was mainly between 1 to 2 kinds, the application of antibiotics ≥4 kinds, and those who didn’t receive any surgery recently accounted for the most. There were statistically significant differences in the distribution of strains between different specimen types, wards occupied and history of ICU stay (P<0.05), but no statistically significant difference in the distribution of strains between different sampling times, number of underlying diseases and types of antibiotics applied (P>0.05). ConclusionThe situation of prevention and control on MDROs in this hospital is still serious. Focus should be placed on high-risk factors’ and infection monitoring and preventive measures should be strengthened to reduce the incidence rate of MDROs infection.

Objective: To understand the interrelationships of parental control, peer relationship, and aggressive behavior in junior high school students, in order to provide a theoretical basis for preventing the occurrence of adolescent aggressive behavior. Methods: During June to July, 2022, 2 564 students of grade one to grade three were selected from 6 junior high schools from each of Suzhou and Xuancheng cities in Anhui Province by using convenient cluster random sampling method, and then the questionnaire survey was administered, including the Chinese version of Parent Control Questionnaire, Chinese version of Buss & Perry Aggression Questionnaire and Adolescent Peer Relationship Questionnaire. Results: Boys scored (185.31±27.49, 21.65±7.43, 21.77 ±8.18, 69.50±11.41, 72.39±11.53) higher than girls (178.21±25.13, 20.08±7.09, 20.61±7.62, 66.56± 11.14 , 70.95± 11.84 ) in parental control, father s psychological control, mother s psychological control, father s behavioral control, and mother s behavioral control ( t =8.63, 5.47, 3.70, 6.60, 3.12), while girls scored (48.41±11.26) higher in peer relationship than boys ( 47.13 ± 10.84 ) ( t =-2.95) ( P <0.01). The scores of first grade students in parental control, father s psychological control, mother s psychological control, father s behavior control, peer relationship, and aggressive behavior (184.67±27.18, 21.83± 7.29 , 22.15±8.07, 68.81±10.95, 50.21±9.57, 80.23±17.66) were higher than those of second gradestudents (180.98±25.46, 20.16±7.82, 20.21±7.55, 68.29±11.69, 45.47±11.67, 74.08±17.70) and third grade students (179.21±26.79, 20.53±7.22, 21.17 ± 8.06 , 66.81± 11.39 , 47.54±11.43, 75.75±16.29) ( F =9.44, 12.87, 13.61, 6.84, 42.85, 30.40, P <0.01). The scores of parental control and peer relationship were positively correlated with the scores of aggressive behavior ( r=0.22, 0.47, P <0.01). Peer relationship partially mediate the relationship between parental control and aggressive behavior, with a partial mediation effect value of 0.04, accounting for 26.39% of the total effect of parental control on aggressive behavior. Conclusions High parental control and poor peer relationship are both positively correlated with the level of aggressive behavior. The peer relationship of teenagers should be improved by establishing appropriate parenting style, tackling campus violence, and maintaining good social norms, in order to reduce the occurrence of aggressive behavior among adolescents.

Objective By analyzing the anti-tumor innovative drug policies text in China,this study aimed to explore the focus and shortcomings of policies related to anti-tumor innovative drugs,and provide the reference for future policy formula-tion and optimization in the field of anti-tumor innovative drug.Methods By accessing the official websites of relevant minis-tries and subordinate institutions such as the Central Committee of the Communist Party of China,the State Council of the People's Republic of China,the National Health Commission of the People's Republic of China,and National Medical Products Administra-tion,and using the keywords"cancer","tumor","anti-tumor drug",and"innovative drug",etc,the national level policies related to the anti-tumor innovative drugs from January 1,2005,to December 31,2022,were collected.Based on a two-dimensional analy-sis framework of policy tools and stakeholders,the collected policy texts were classified,encoded,and statistically analyzed.Results A total of 30 policy texts were involved,and a total of 90 policy codes were generated.There were 24,43,and 23 codes for demand-based policy tools,environmental policy tools,and supply-based policy tools,accounting for 26.67%,47.78%,and 25.56%,respectively.Based on policy tools and stakeholders,a total of 183 codes were generated,with government departments,pharmaceutical enterprises,medical institutions,and patients having 70,36,54,and 23 codes respectively,accounting for 38.25%,19.67%,29.51%,and 12.57%.Conclusions China had the highest proportion of environmental policy tools in the application of innovative anti-tumor drug policies,while supply-oriented and demand-oriented policy tools were underutilized,resulting in an overall imbalance in application;The distribution pattern of stakeholders was not coordinated,with government departments and medical institutions having higher attention than pharmaceutical enterprises and patients..It was necessary to reasonably promote the collaborative application of anti-tumor innovative drug policy tools,scientifically plan the layout of anti-tumor innovative drug policy sub-tools,and balance the interests of all stakeholders to ensure the efficient implementation of the policies.

Objective:To explore the impact of baseline remnant cholesterol levels at a single time point and cumulative remnant cholesterol exposure on the progression trajectories of arterial stiffness.Methods:This prospective cohort study included 2 401 eligible participants from the Beijing Health Management Cohort who consecutively attended health examinations in 2010-2011, 2012-2013, and 2014-2015. The remnant cholesterol value measured in 2014-2015 served as the baseline remnant cholesterol level at a single time point. The cumulative exposure indices were calculated based on remnant cholesterol values from three health examinations from 2010 to 2015, including cumulative exposure, cumulative exposure burden, and duration of high remnant cholesterol exposure. Arterial stiffness was assessed by brachial-ankle pulse wave velocity (baPWV). The follow-up continued until December 31, 2019, with annual check-ups. During the follow-up period, a group-based trajectory model was employed to construct the progression trajectories of baPWV. The associations between the baseline remnant cholesterol level, cumulative exposure indices of remnant cholesterol and baPWV trajectories were examined using ordinal logistic regression models, adjusting for traditional cardiovascular risk factors and low-density lipoprotein cholesterol (LDL-C) levels.Results:The age of the 2 401 participants was 61 (54, 69) years, with 1 801 (75.01%) being male. The group-based trajectory model indicated that the best-fit model categorized the participants into three subgroups: low-rising group (1 036 individuals, 43.15%), moderate-rising group (1 137 individuals, 47.36%), and high-rising group (228 individuals, 9.50%). After adjusting for traditional cardiovascular risk factors, baseline remnant cholesterol levels at a single point ( OR=1.170, 95% CI: 1.074-1.274), cumulative remnant cholesterol exposure ( OR=1.194, 95% CI: 1.096-1.303), cumulative remnant cholesterol exposure burden ( OR=1.270, 95% CI: 1.071-1.507), and high-remnant cholesterol exposure duration (6 years: OR=1.351, 95% CI: 1.077-1.695) were significantly associated with the risk of developing a poor baPWV progression trajectory. These results remained significant after adjusting for cumulative average LDL-C levels. The association between baseline remnant cholesterol levels and baPWV progression became insignificant after adjusting for cumulative remnant cholesterol levels ( OR=1.053, 95% CI: 0.923-1.197), while the association between cumulative remnant cholesterol exposure and baPWV progression remained significant after adjusting for baseline remnant cholesterol levels ( OR=1.145, 95% CI: 1.008-1.305). Conclusions:Higher levels of baseline remnant cholesterol and cumulative remnant cholesterol are independent risk factors for the progression of arterial stiffness. These associations remain significant even after adjusting for traditional cardiovascular risk factors and LDL-C levels. Furthermore, the effect of cumulative remnant cholesterol levels on the progression of arterial stiffness was stronger than the effect of baseline remnant cholesterol levels.

Objective:To investigate the incidence and prothrombotic risk factors of postoperative venous thromboembolism(VTE) in Cushing′s disease and to further develop an assessment model to identify those at high risk of postoperative VTE events.Methods:A retrospective study was performed in 82 patients who were admitted to Huashan Hospital, Fudan University during January 2019 and January 2020 and diagnosed with Cushing′s disease. These patients underwent the evaluation about their clinical, hormonal, and coagulation parameters, as well as ultrasonography and pulmonary angio-CT when necessary. The least absolute shrinkage and selection operator(LASSO) regression analysis was used to screen independent risk factors, and a nomogram model for postsurgical VTE risk assessment in Cushing′s disease was initially established, and Bootstrap method was used for internal verification. Finally, the predictive model was evaluated for calibration and clinical applicability in the study cohort.Results:Nineteen patients(23.17%) developed VTE events, with 14 cases occurring after endoscopic transsphenoidal surgery. Compared to patients without VTE, those in the VTE group were older( P<0.001), had longer postoperative bed rest, higher rates of current infection, higher HbA 1C levels, and more severe glucose tolerance impairment(all P<0.05). Through LASSO regression analysis, two independent risk factors for postoperative VTE were identified: Age and current infection. Then a VTE risk assessment nomogram model was established to predict the patients at high risk of VTE. In the nomogram model for VTE risk assessment, the area under the receiver operating characteristic curve was 0.868(95% CI 0.787-0.949), with the calibration curve closely aligning with the ideal diagonal line and the clinical decision curve exceeding the two extreme curves. Conclusions:Advanced perioperative assessment needs to be taken to screen those with high VTE risks in patients diagnosed with Cushing′s disease. Additionally, during the perioperative period, patients with Cushing′s disease should undergo mandatory physical activity or prophylactic anticoagulant therapy.

【Objective】 To investigate the application value of three-dimensional printed guiding device in sacral neuromodulation in children. 【Methods】 A total of 17 patients admitted during Jan.2017 and Nov.2022 were divided into two groups: control group (n=8), using traditional method to locate sacral foramen for puncture; three-dimensional printed guiding device group (n=5), using three-dimensional printing technology to make individual guiding device for puncture. The clinical indexes of the two groups were evaluated, including puncture time, puncture numbers, intraoperative X-ray exposure times, postoperative evaluation time and second-stage conversion rate. The evaluation indexes of postoperative complications were wound bleeding, wound infection, wound rupture, electrode fracture, displacement or prolapse. 【Results】 In the control group, 1 case was diagnosed as bladder-bowel dysfunction, the remaining 7 were neurogenic bladder; in the three-dimensional printed guiding device group, all 9 cases were diagnosed as neurogenic bladder. The puncture time was shorter in the three-dimensional printed guiding device group than in the control group [85(70-90) min vs.138(133-208) min], the puncture numbers were fewer [15(12-20) vs.22(18-26)], and the X-ray exposure times were fewer [12(12-17) vs.19(16-23)] (all P<0.05). The initial stimulation voltage, postoperative evaluation time and second-stage conversion rate were not statistically significant. 【Conclusion】 Compared with the traditional method, the use of three-dimensional printed guiding device can reduce the puncture numbers and shorten the puncture time in the process of sacral neuromodulation in children.

Pediatric acute respiratory distress syndrome(PARDS) is a common clinical syndrome in pediatric intensive care unit, and a serious threat to children′s life health.The standardized diagnosis and management of PARDS is very important.Insufficient understanding of PARDS by clinical physician may delay diagnosis and treatment, worsen disease progression, and lead to serious consequences such as irreversible lung injury.The diagnosis and management guidelines for PARDS has been updated in The Second Pediatric Acute Lung Injury Consensus Conference (PALICC-2). This article focuses on the definition, diagnosis, management strategies, and other aspects of PARDS in PALICC-2 for clinical reference, in order to improve the standardized diagnosis and management level of pediatric physicians for PARDS.

Objective:To study the factors influencing survival after radical resection in patients with intrahepatic cholangiocarcinoma (ICC), and to construct a nomogram on survival prediction.Methods:The clinical data of 139 patients with ICC who underwent radical resection at the People's Hospital of Zhengzhou University from June 2018 to December 2021 were retrospectively analyzed. There are 69 males and 70 females, aged (59.5±10.2) years old. These patients were divided into two groups based on a 3: 1 ratio by using the random number method: the test group ( n=104) and the validation group ( n=35). Data from the test group was used to construct a nomagram and data from the validation group was used to validate the predictive power of the nomagram. Univariate and multivariate Cox regression analyses were used to analyse factors influencing survival on the test group patients and to construct a nomogram. The predictive accuracy of the nomogram was determined by receiver operating characteristic (ROC) curves, concordance index (C-index) and calibration curves. Results:The results of the multivariate regression analysis showed that a combined hemoglobin, albumin, lymphocyte and platelet immunoinflammation (HALP) score <37.1 ( HR=1.784, 95% CI: 1.047-3.040), CA19-9 > 35U/ml ( HR=2.352, 95% CI: 1.139-4.857), poorly differentiated tumor ( HR=2.475, 95% CI: 1.237-4.953) and vascular invasion ( HR=1.897, 95% CI: 1.110-3.244) were independent risk factors that affected prognosis of patients with ICC after radical resection (all P<0.05). The AUCs of the nomogram in the test group in predicting the overall survival at 1, 2 and 3 years of patients with ICC after radical resection were 0.808, 0.853 and 0.859, respectively. There was good consistency between the prediction of the nomogram and actual observation. The predicted C-index of the total survival period of the test group was 0.765 (95% CI: 0.704-0.826), and the C-index of the validation group was 0.759 (95% CI: 0.673-0.845). Conclusion:A HALP score <37.1, CA19-9>35 U/ml, poorly differentiated tumour and vascular invasion were independent risk factors for prognosis of ICC patients after radical resection. The nomogram was established based on the above factors and showed good performance in predicting overall survival after radical resection in patients with ICC.

The spinal fracture in patients with ankylosing spondylitis (AS) is predominantly unstable, involving all three columns of the spine. If AS combined with spinal fracture is not effectively treated in the early stage, continuous stress on the lesion site may result in pseudarthrosis, progressive kyphotic deformity, neurologic deficits and other complications during later stages. Currently, the diagnosis of AS combined with spinal fracture mainly relies on symptoms, signs and imaging examination. However, there is a certain rate of missed diagnoses. Although surgical intervention is preferred, there is no unified standard for selecting the surgical approaches. Anterior cervical surgery, due to potential risks of unstable fixation and vascular nerve damage, is limited to a selected group of AS patients combined with concurrent cervical spine fracture. The combined anterior and posterior approach provides good stability, but patients may not tolerate the surgical trauma. The traditional posterior open surgery is widely employed and can achieve good results, but it also causes significant surgical trauma and intraoperative bleeding. Minimally invasive posterior percutaneous procedures are becoming more and more popular due to its advantages of less trauma, less bleeding and faster recovery. Additionally, the use of robot-assisted and navigation techniques increases both safety and accuracy during operations. In this study, the authors reviewed the progress in the diagnosis and treatment of AS combined with spinal fracture, providing references for optimizing diagnostic and therapeutic strategies.
