Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective:To evaluate the effect of Salvianolic acid B (Sal B) on the inflammatory responses of vascular smooth muscle cells (VSMCs) in septic mice and the role of circACTA2.Methods:In vivo experiment Eighty-one healthy male C57BL/6 mice, aged 6-8 weeks, were divided into 3 groups ( n=27 each) by a random number table method: sham operation group, sepsis group and Sal B group. Sepsis model was developed by cecal ligation and puncture. After sucessful preparation of the model, Sal B 7 mg/kg/d was intraperitoneally injected once a day for 2 consecutive days in Sal B group. Twenty mice in each group were randomly selected to measure systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and whole blood lactic acid (Lac) and to record the survival within 7 days after developing the model. Seven mice in each group were randomly selected at 48 h after developing the model, and the arterial vascular tissues were collected for determination of the expression of interleukin-1beta (IL-1β) (by immunofluorescence staining), expression of IL-1β, tumor necrosis factor-alpha (TNF-α) and IL-6 protein and mRNA (by Western blot and quantitative real-time polymerase chain reaction, respectively), and expression of circACTA2 (by quantitative real-time polymerase chain reaction). Cell experiment Mouse VSMCs were cultured and divided into 6 groups ( n=3 each) by a random number table method: control group (C group), lipopolysaccharide (LPS) group, Sal B group, si-circACTA2+ C group, si-circACTA2+ LPS group, and si-circACTA2+ Sal B group. The cells were incubated for 24 h with LPS (final concentration 1 μg/ml) in LPS group and with LPS (final concentration 1 μg/ml) and Sal B (final concentration 5 μmol/L) in Sal B group. VSMCs were transfected with si-circACTA2 only in si-circACTA2+ C group. At 24 h after transfection of si-circACTA2 into VSMCs, the cells were incubated with LPS (final concentration 1 μg/ml) in si-circACTA2+ LPS group and with LPS (final concentration 1 μg/ml) and Sal B (final concentration 5 μmol/L) for 24 h in si-circACTA2+ Sal B group. The expression of IL-1β, TNF-α and IL-6 protein and mRNA was detected using Western blot and quantitative real-time polymerase chain reaction, and the expression of circACTA2 was determined by the quantitative real-time polymerase chain reaction. Results:In vivo experiment Compared with sham operation group, SBP, DBP and MAP were significantly decreased, the concentrations of whole blood Lac were increased, 7-day survival rate was decreased, the expression of IL-1β, TNF-α and IL-6 protein and mRNA in arterial vascular tissues was up-regulated, circACTA2 expression was down-regulated ( P<0.05), and the fluorescence of IL-1β was enhanced in sepsis group. Compared with sepsis group, SBP, DBP and MAP were significantly increased, whole blood Lac concentrations were decreased, 7-day survival rate was increased, the expression of IL-1β, TNF-α and IL-6 protein and mRNA in arterial vascular tissues was down-regulated, the expression of circACTA2 was up-regulated ( P<0.05), and the fluorescence of IL-1β was weakened in Sal B group. Cell experiment Compared with group C, the expression of IL-1β, TNF-α and IL-6 protein and mRNA was significantly up-regulated, and the expression of circACTA2 was down-regulated in LPS group ( P<0.05). Compared with LPS group, the expression of IL-1β, TNF-α and IL-6 protein and mRNA was significantly down-regulated, and the expression of circACTA2 was up-regulated in Sal B group ( P<0.05). Compared with si-circACTA2+ C group, the expression of IL-1β, TNF-α and IL-6 protein and mRNA was significantly up-regulated in si-circACTA2+ LPS group ( P<0.05). There were no significant differences in the expression of IL-1β, TNF-α and IL-6 protein and mRNA between si-circACTA2+ LPS group and si-circACTA2+ Sal B group ( P>0.05). Conclusions:Sal B can reduce the inflammatory responses of VSMCs, and the mechanism may be related to promoting the expression of circACTA2 in septic mice.

Objective:To explore the mechanism of Huangqi Jiedu Decoction (HQJD) in the treatment of breast cancer with the syndrome of Zheng deficiency and toxic incandescence by network pharmacology and molecular docking technology.Methods:The main active ingredients and targets of HQJD were screened through the traditional Chinese medicine (TCM) systematic pharmacology database and analysis platform. The relevant targets of breast cancer with the syndrome of Zheng-deficiency, toxic-incandescence were obtained using OMIM, GeneGards and Drugbank databases, and the relevant targets of HQJD for the treatment of breast cancer with the syndrome of Zheng-deficiency and toxic incandescence were obtained by intersection; The Cytoscape 3.9.1 software was used to build the protein protein interaction (PPI) network and the " drug active component target disease" network on the basis of String 11.0 database, and the core active components and core targets of HQJD in treating breast cancer with the syndrome of Zheng-deficiency and toxic-incandescence were inferred according to the topological parameters. gene ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were performed on core targets using R language; and molecular docking verification on the main active ingredients and core targets were conducted.Results:230 effective targets of active ingredients of HQJD were screened, and 15 467 active ingredients of breast cancer with syndrome of Zheng-deficiency/toxic-incandescence were obtained; 217 intersection targets; GO function enrichment analysis showed that the treatment of HQJD for breast cancer with the syndrome of Zheng-deficiency and toxic-incandescence mainly involved oxidative stress and cytochemical stress; The enrichment analysis of KEGG pathway showed that HQJD treatment of breast cancer with the syndrome of Zheng-deficiency and toxic-incandescence was mainly related to phosphatidylinositol 3-protein kinase B (PI3K-Akt), interleukin-17 (IL-17) and other signal pathways. The molecular docking results showed that the main active ingredients such as β-sitosterol, stigmasterol, luteolin had good binding ability with core targets.Conclusions:HQJD has the characteristics of multi-component, multi target and multi pathway in the treatment of breast cancer with syndrome of Zheng-deficiency and toxic-incandescence, and its main mechanism may be related to PI3K-Akt, IL-17, P53 and other signal pathways.

In recent years, nucleic acid therapy, as a revolutionary therapeutic tool, has shown great potential in the treatment of genetic diseases, infectious diseases and cancer. Lipid nanoparticles (LNPs) are currently the most advanced mRNA delivery carriers, and their emergence is an important reason for the rapid approval and use of COVID-19 mRNA vaccines and the development of mRNA therapy. Currently, mRNA therapeutics using LNP as a carrier have been widely used in protein replacement therapy, vaccines and gene editing. Conventional LNP is composed of four components: ionizable lipids, phospholipids, cholesterol, and polyethylene glycol (PEG) lipids, which can effectively load mRNA to improve the stability of mRNA and promote the delivery of mRNA to the cytoplasm. However, in the face of the complexity and diversity of clinical diseases, the structure, properties and functions of existing LNPs are too homogeneous, and the lack of targeted delivery capability may result in the risk of off-targeting. LNPs are flexibly designed and structurally stable vectors, and the adjustment of the types or proportions of their components can give them additional functions without affecting the ability of LNPs to deliver mRNAs. For example, by replacing and optimizing the basic components of LNP, introducing a fifth component, and modifying its surface, LNP can be made to have more precise targeting ability to reduce the side effects caused by treatment, or be given additional functions to synergistically enhance the efficacy of mRNA therapy to respond to the clinical demand for nucleic acid therapy. It is also possible to further improve the efficiency of LNP delivery of mRNA through machine learning-assisted LNP iteration. This review can provide a reference method for the rational design of engineered lipid nanoparticles delivering mRNA to treat diseases.

Objective To investigate the epidemiological characteristics and mutation spectrum of monogenic diseases in Chinese population through a large-scale,multicenter carrier screening.Methods This study was conducted among a total of 33 104 participants(16 610 females)from 12 clinical centers across China.Carrier status for 223 genes was analyzed using high-throughput sequencing and different PCR methods.Results The overall combined carrier frequency was 55.58%for 197 autosomal genes and 1.84%for 26 X-linked genes in these participants.Among the 16 669 families,874 at-risk couples(5.24%)were identified.Specifically,584 couples(3.50%)were at risk for autosomal genes,306(1.84%)for X-linked genes,and 16 for both autosomal and X-linked genes.The most frequently detected autosomal at-risk genes included GJB2(autosomal recessive deafness type 1A,393 couples),HBA1/HBA2(α-thalassemia,36 couples),PAH(phenylketonuria,14 couples),and SMN1(spinal muscular atrophy,14 couples).The most frequently detected X-linked at-risk genes were G6PD(G6PD deficiency,236 couples),DMD(Duchenne muscular dystrophy,23 couples),and FMR1(fragile X syndrome,17 couples).After excluding GJB2 c.109G>A,the detection rate of at-risk couples was 3.91%(651/16 669),which was lowered to 1.72%(287/16 669)after further excluding G6PD.The theoretical incidence rate of severe monogenic birth defects was approximately 4.35‰(72.5/16 669).Screening for a battery of the top 22 most frequent genes in the at-risk couples could detect over 95%of at-risk couples,while screening for the top 54 genes further increased the detection rate to over 99%.Conclusion This study reveals the carrier frequencies of 223 monogenic genetic disorders in the Chinese population and provides evidence for carrier screening strategy development and panel design tailored to the Chinese population.In carrier testing,genetic counseling for specific genes or gene variants can be challenging,and the couples need to be informed of these difficulties before testing and provided with options for not screening these genes or gene variants.

Objective To establish the finite element model of spinal canal reconstruction and internal fixation,analysis influence of spinal canal reconstruction and internal fixation on spinal stability,and verify the effectiveness and reliability of spinal canal reconstruction and internal fixation in spinal canal surgery.Methods A 30-year-old male healthy volunteer with a height of 172 cm and weight of 75 kg was selected and his lumbar CT data were collected to establish a finite element model of normal lumbar Lo3-L,and the results were compared with in vitro solid results and published finite element analysis results to verify the validity of the model.They were divided into normal group,laminectomy group and spinal canal reconstruction group according to different treatment methods.Under the same boundary fixation and physiological load conditions,six kinds of ac-tivities were performed,including forward bending,backward extension,left bending,right bending,left rotation and right rota-tion,and the changes of range of motion(ROM)of L3-L4,L4-L5 segments and overall maximum ROM of L3-L5 were analyzed under the six conditions.Results The ROM displacement range of each segment of the constructed L3-L5 finite element model was consistent with the in vitro solid results and previous literature data,which confirms the validity of the model.In L3-L4,ROM of spinal canal reconstruction group was slightly increased than that of normal group during posterior extension(＞5％dif-ference),and ROM of other conditions was similar to that of normal group(＜5％difference).ROM in laminectomy group was significantly increase than that in normal group and spinal canal reconstruction group under the condition of flexion,extension,left and right rotation.In L4-L5,ROM in spinal canal reconstruction group was similar to that in normal group(＜5％differ-ence),while ROM in laminectomy group was significantly higher than that in normal group and spinal canal reconstruction group(＞5％difference).In the overall maximum ROM of L3-L5,spinal canal reconstruction group was only slightly higher than normal group under the condition of posterior extension(＞5％difference),while laminectomy was significantly higher than normal group and spinal canal reconstruction group under the condition of anterior flexion,posterior extension,left and right rotation(＞5％difference).The changes of each segment ROM and overall ROM of L3-L5 showed laminectomy group＞spinal canal reconstruction group＞normal group.Conclusion Laminectomy could seriously affect biomechanical stability of the spine,but application of spinal canal reconstruction and internal fixation could effectively reduce ROM displacement of the responsi-ble segment of spine and maintain its biomechanical stability.

Objective To investigate disease characteristics and hospitalization costs of children with Mycoplasma Pneumoniae pneumonia(MPP)admitted to Shanghai municipal medical hospitals from 2019 to 2023.Methods Depending on the Shanghai Municipal Hospital Pediatric Alliance,we retrospectively investigated community acquired MPP pediatric patients hospitalized in 22 municipal hospitals with pediatric qualifications(including 4 children's hospitals)in Shanghai from Jan 2019 to Dec 2023.We collected the patients'diagnosis codes,gender,age,length of hospital stay,hospitalization costs,and whether they progressed to severe Mycoplasma pneumoniae pneumonia(SMPP).Results From 2019 to 2023,a total of 29 045 hospitalized children with MPP were treated,with 6 035 cases(20.8%)identified as SMPP in the 22 hospitals.Trend analysis revealed a rising trend with years in the proportion of SMPP patients(χ2trend=365.498,P<0.001).Among the 4 children's hospitals,there were 18 710 cases with MPP,including 4 078 cases(21.8%)of SMPP.The proportion of SMPP patients also showed an increasing trend with years(χ2trend=14.548,P<0.001),and the proportion in 2023(23.0%)was higher than that in previous years with statistical significance.There were statistical differences in the seasonal distribution of MPP cases between different years,with higher proportions in summer and autumn overall.The age distribution of hospitalized MPP children varied among different years,with school-age children accounting for the majority(56.8%)in 2023.There was no difference in the distribution of severe cases between different genders,but there were differences in the proportion of severe cases among different age groups in different years,with a gradual increase in severe cases among children aged 1 to 3 years(χ2trend=191.567,P<0.001).The average length of hospital stay for MPP during the epidemic was higher than that during non-epidemic periods,and there were statistically significant differences in the average length of hospital stay between different years(P<0.001).The individual hospitalization costs during the epidemic were higher than in other years,and there were statistically significant differences in individual hospitalization costs between different years(P<0.001).The total hospitalization costs were still higher in 2019 and 2023.The individual hospitalization costs for SMPP were higher than for non-SMPP cases.Conclusion MPP outbreaks occurred in Shanghai in 2019 and 2023,with the higher proportions in summer and autumn overall.Compared to previous years,the number of hospitalized MPP children in Shanghai was higher in 2023,with a higher proportion of SMPP cases,especially among children under 3 years old.The individual per capita hospitalization expenses for SMPP cases were higher than for non-SMPP cases.

Objective:To explore the current status of decision conflict in breast cancer patients with immediate breast reconstruction, and analysis the relationship with personality traits, which can provides new ideas for understanding decision-making behavior and promotes effective decision-making.Methods:A cross-sectional survey was conducted to select 175 breast cancer patients who met the inclusion and exclusion criteria for immediate breast reconstruction in Cancer Hospital of Tianjin Medical University from May to December 2022 by convenient sampling method. A questionnaire was conducted using the general information questionnaire, Revised NEO Personality Inventory, Decisional Conflict Scale, and the Control Preference Scale. Single factor analysis and multiple linear regression were used to analyze the current situation and influencing factors of decision-making conflict.Results:The 175 patients with immediate breast reconstruction were all female, aged 24-67(45.26 ± 8.01) years. The decision conflict score of 175 breast cancer patients with immediate breast reconstruction was (25.05 ± 7.05), the standardized decision conflict score was (39.14 ± 10.04), the dimension score of factors affecting decision making was(7.18 ± 2.58), the score of decision uncertainty dimension was (7.34 ± 2.28). 37 patients (21.14%) had no decision conflict, 64 patients (36.57%) had moderate decision conflict, and 74 patients (42.29%) had high level decision conflict. The scores of altruism, neuroticism, openness, sociality and moral sense of patients in this survey were (15.16 ± 3.43), (18.14 ± 4.95), (13.71 ± 3.71), (18.12 ± 4.40) and (17.46 ± 4.03) respectively. The decision conflict was negatively correlated with altruism, sociality and moral sense ( r=-0.355, -0.543, -0.331, all P<0.05), and positively correlated with neuroticism( r=0.208, P<0.05). Multivariate regression analysis showed that age, decision type, neuroticism and sociality were the influencing factors of decision conflict ( F=16.39, P<0.05), accounted for 47.1% of the variation. The variance inflation factor of the above variables was less than 10, indicating no collinearity. Conclusions:The decision conflict of breast cancer patients with immediate breast reconstruction needs to be improved urgently. Based on the influencing factors (age, decision-making type and personality traits) of decision conflict, medical staff should implement personalized decision-making aid process to meet decision-making information needs, reduce decision-making conflict and optimize decision-making quality.

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.
