Objective:To propose policy recommendations for the compensation mechanism of high-quality development of municipal public hospitals.Methods:Taking the municipal public hospitals in Shanghai as the research object,the aspects of financial subsidies,the structure of medical service income,investment in scientific research and education,and other social compensations were examined to conduct a systematic simulation of the operation of the average municipal public hospital in Shanghai under different policy intervention scenarios.Results:If the current conditions remain unchanged,the average municipal public hospital in Shanghai will face a deficit starting in 2032,the proportion of income from examinations and laboratory tests will surpass that of medical service income in 2026 and 2031,respectively.If the hospitals follow a plan of Combination Plan 3,4,and 5,the average municipal public hospital in Shanghai will be able to break even from 2023 to 2033,and the structure of medical service income will be significantly optimized.Conclusion:To establish a new compensation mechanism for high-quality hospital development that enhances medical services,it is recommended to optimize the structure of government financial compensation,explore rational pricing strategies based on categories,increase investment in scientific research and education while paying attention to the transformation of scientific and technological achievements,expand compensation channels for public hospitals,and improve relevant laws and regulations.

Objective:To establish 30-day of age transcutaneous bilirubin (TcB) reference curves for healthy neonates, and to investigate regional variations in bilirubin dynamics.Methods:A multicenter retrospective cohort study was conducted. A total of 220 950 healthy neonates born at a gestational age of 35-<42 weeks, with a birth weight ≥2 000 g, who did not receive phototherapy within 60 h after birth were recruited. All of them underwent remote TcB monitoring using the Bilibaby remote jaundice monitoring system between August 1 st, 2020 and December 31 st, 2024 in 426 hospitals. TcB data were collected within the period from birth to 30-day of age. The P40, P75, and P95 of TcB values were calculated, and dynamic TcB curves for 30-day of age were constructed. Patterns of bilirubin change, rates of change, and transition outcomes were described. Regional comparisons between South and North were conducted using linear mixed-effects models for TcB trajectories and Pearson′s chi-square test for outcome differences. Results:A total of 220 950 neonates were included, of whom 101 711 (46.03%) were female. Gestational age at birth was (38.75±1.12) weeks, and birth weight was (3 272±417) g. TcB levels increased rapidly within 3-day of age, peaked at 4-6-day of age, with peak values at P40, P75, and P95 of 200.6, 239.7 and 275.4 μmol/L (11.8, 14.1 and 16.2 mg/dl), respectively. TcB levels gradually declined thereafter and stabilized after 13-day of age, with values at P40, P75, and P95 fluctuating between 147.9-159.8, 190.4-200.6, and 231.2-239.7 μmol/L (8.7-9.4, 11.2-11.8, 13.6-14.1 mg/dl), respectively. Notably, among neonates categorized as low-or low-intermediate-risk within 3-day of age, 6 700 (12.76%) progressed to intermediate-high or high risk between 4 and 30 days of age. Before 13-day of age, TcB levels in the southern regions were consistently higher than those in the northern regions ( P=0.039); from 14 to 30 days of age, the overall TcB levels had no statistically difference, but the temporal changes in TcB still showed regional differences (degrees of freedom=3, all interaction P<0.05). Among neonates classified as low-or low-intermediate risk within 3-day of age, 25 326 were from southern regions, of whom 4 254 (16.80%) progressed to intermediate-high or high risk between 4 and 30 days of age. In northern regions, 27 193 neonates were classified as low-or low-intermediate risk within 3-day of age, among whom 2 446 (8.99%) progressed to intermediate-high or high risk. The risk progression between the 2 regions had statistically difference ( χ2=716.49, P<0.001). Conclusions:A TcB percentile curve for neonates within 30-day of age was established, revealing that both the overall TcB level and its temporal trend were higher in southern than in northern newborns. These findings provide baseline data to support continuous management of neonatal jaundice.

In recent years,the market share of food and medicine homology substances has continued to grow,and various types of contamination issues have become the focus of attention both inside and outside the industry.The contamination not only affects the original medicinal quality,but also leads to the accumulation of toxic substances in the human body,causing acute and chronic severe hazards such as vomiting,poisoning and cancer.Therefore,the development of biosensors that can conveniently,accurately and sensitively detect various pollutants in food and medicine homology substances has become a research hotspot.Aptasensors based on metal-organic frameworks(MOFs)with advantages such as strong specificity,rapid response and simple operation,have been widely used in detection of various pollutants.This review focused on the research progress of aptasensors based on MOFs for detection of food and medicine homology contamination in the past few years,and provided a detailed comparison and analysis for detection of chemical pollutants(such as pesticide residues,heavy metal residues,mycotoxins,etc.)and microbial contamination in food and medicine homology substances.Besides,the development trend and possible challenges of MOFs aptasensors in detection of food and medicine homology substances in the future were discussed,which was anticipated to provide a reference for the development of new MOFs aptasensors.

Objective: To investigate the resistance to rifampicin and isoniazid and the changing trends among patients with pulmonary tuberculosis in Luohu District, Shenzhen City, Guangdong Province from 2012 to 2022, so as to provide insights into improving drug-resistant pulmonary tuberculosis control and prevention strategies. Methods: Basic information, treatment classification and drug resistance data of patients with pulmonary tuberculosis and positive pathogenic detection in Luohu District from 2012 to 2022 were collected through the Tuberculosis Surveillance System of Chinese Disease Prevention and Control Information System, and resistance rates of rifampicin and isoniazid and the changing trends were analyzed. Results: A total of 2 126 patients with pulmonary tuberculosis were collected and had a median age of 34 (interquartile range, 25) years, including 1 334 males (62.75%) and 792 females (37.25%). There were 302 patients with drug-resistance in Luohu District from 2012 to 2022, with a resistance rate of 14.21%. Among them, 60 patients were monoresistant to rifampicin (2.82%), 113 patients were monoresistant to isoniazid (5.32%), and 129 patients were multidrug resistant (6.07%). The rate of rifampicin monoresistance showed a downward trend from 2012 to 2022, while the rate of multidrug resistance showed an upward trend (both P<0.05). There was no significant tendency in the rate of isoniazid monoresistance (P>0.05). The rate of multidrug resistance among patients without Shenzhen residence was higher than that among patients with Shenzhen residence; the rates of rifampicin resistance and multidrug resistance among retreated patients were higher than those among treatment-naïve patients (all P<0.05). Conclusions The rate of rifampicin monoresistance appeared a downward trend and the rate of multidrug resistance appeared an upward trend among patients with pulmonary tuberculosis in Luohu District from 2012 to 2022. Attention should be given to non-Shenzhen residence and retreated patients.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the clinical characteristics and prognosis of pneumococcal meningitis(PM),and drug sensitivity of Streptococcus pneumoniae(SP)isolates in Chinese children.Methods A retrospective analysis was conducted on clinical information,laboratory data,and microbiological data of 160 hospitalized children under 15 years old with PM from January 2019 to December 2020 in 33 tertiary hospitals across the country.Results Among the 160 children with PM,there were 103 males and 57 females.The age ranged from 15 days to 15 years,with 109 cases(68.1% )aged 3 months to under 3 years.SP strains were isolated from 95 cases(59.4% )in cerebrospinal fluid cultures and from 57 cases(35.6% )in blood cultures.The positive rates of SP detection by cerebrospinal fluid metagenomic next-generation sequencing and cerebrospinal fluid SP antigen testing were 40% (35/87)and 27% (21/78),respectively.Fifty-five cases(34.4% )had one or more risk factors for purulent meningitis,113 cases(70.6% )had one or more extra-cranial infectious foci,and 18 cases(11.3% )had underlying diseases.The most common clinical symptoms were fever(147 cases,91.9% ),followed by lethargy(98 cases,61.3% )and vomiting(61 cases,38.1% ).Sixty-nine cases(43.1% )experienced intracranial complications during hospitalization,with subdural effusion and/or empyema being the most common complication[43 cases(26.9% )],followed by hydrocephalus in 24 cases(15.0% ),brain abscess in 23 cases(14.4% ),and cerebral hemorrhage in 8 cases(5.0% ).Subdural effusion and/or empyema and hydrocephalus mainly occurred in children under 1 year old,with rates of 91% (39/43)and 83% (20/24),respectively.SP strains exhibited complete sensitivity to vancomycin(100% ,75/75),linezolid(100% ,56/56),and meropenem(100% ,6/6).High sensitivity rates were also observed for levofloxacin(81% ,22/27),moxifloxacin(82% ,14/17),rifampicin(96% ,25/26),and chloramphenicol(91% ,21/23).However,low sensitivity rates were found for penicillin(16% ,11/68)and clindamycin(6% ,1/17),and SP strains were completely resistant to erythromycin(100% ,31/31).The rates of discharge with cure and improvement were 22.5% (36/160)and 66.2% (106/160),respectively,while 18 cases(11.3% )had adverse outcomes.Conclusions Pediatric PM is more common in children aged 3 months to under 3 years.Intracranial complications are more frequently observed in children under 1 year old.Fever is the most common clinical manifestation of PM,and subdural effusion/emphysema and hydrocephalus are the most frequent complications.Non-culture detection methods for cerebrospinal fluid can improve pathogen detection rates.Adverse outcomes can be noted in more than 10% of PM cases.SP strains are high sensitivity to vancomycin,linezolid,meropenem,levofloxacin,moxifloxacin,rifampicin,and chloramphenicol.[Chinese Journal of Contemporary Pediatrics,2024,26(2):131-138]

Objective To investigate the role and mechanism of β-catenin protein in the maintenance of malignant biological characteristics of pancreatic cancer stem cells.Methods Primary pancreatic cancer cells were isolated and cultured,then divided into the negative control(NC)group and the AD β-catenin group,cells in the NC group were transfected with negative empty vectors,and cells in the AD β-catenin group were transfected with β-catenin overexpression lentiviral vectors.Flow cytometry was used to analyze the expression of tumor stem cell surface markers CD24,CD44,and ESA.CD24+CD44+ESA+cells were sorted and expanded in culture,and their sphere-forming ability,colony-forming ability,proliferation ability,invasion ability and migration ability,cell cycle,and apoptosis were assessed.The impact of β-catenin overexpression on the biological characteristics of pancreatic cancer stem cells was analyzed.Results The relative expression levels of β-catenin mRNA and protein in the AD β-catenin group were significantly higher than those in the NC group(P=0.016,P=0.015).Flow cytometry analysis revealed that the percentage of CD24+and CD24+CD44+ESA+cells in the AD β-catenin group was significantly higher than that in the NC group(P<0.05).Compared with the NC group,the colony-forming ability,sphere-forming ability,numbers of invasion and migration of pancreatic cancer stem cells in the AD β-catenin group were significantly increased(P<0.05).The optical density(OD)values at 24 hours,48 hours,and 72 hours were significantly higher in the AD β-catenin group than those in the NC group(P<0.05).Compared with the NC group,the proportion of G0/G1 phase cells in the AD β-catenin group was significantly decreased(P<0.05),and the proportion of S phase cells was increased(P<0.05).The apoptosis rate in the AD β-catenin group was significantly lower than that in the NC group(P<0.05).Conclusion β-catenin can improve the percentage of CD24+CD44+ESA+cells in primary pancreatic cancer cells,promote sphere-forming ability,enhance cell proliferation,invasion,and migration,and inhibit cell apoptosis,thereby maintaining the malignant biological characteristics of pancreatic cancer stem cells.
