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.

Abnormal tumour cell adhesion is a key step in tumour metastasis， in which weakened homologous and enhanced heterologous adhesion of tumour cells is an important cause of tumour metastasis. Chronic stress can activate the sympathetic nervous system to link and regulate the homologous and heterologous adhesion of tumour cells and exacerbate tumour metastasis. Combining the understanding of traditional Chinese medicine （TCM） and Western medicine on tumour metastasis， it is believed that the mechanism of "qi constraint and stagnation， tumor toxin transmission and retention" in TCM theory is highly related to the abnormal adhesion of tumour cells triggered by chronic stress. Qi constraint and stagnation is closely related to chronic stress and its activation of the sympathetic nervous system， and transmission and retention of tumor toxin explained the mechanism of tumour metastasis due to abnormal adhesion of tumour cells from the perspective of TCM. By regulating the key link of sympathetic nervous system-tumour cell adhesion， application of the formulas of regulating qi and resolving toxin can improve chronic stress and inhibit tumour metastasis.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

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.

Objectives: This study aimed to present the Asia-Pacific consensus on long-term and sequential therapy for osteoporosis, offering evidence-based recommendations for the effective management of this chronic condition.The primary focus is on achieving optimal fracture prevention through a comprehensive, individualized approach. Methods: A panel of experts convened to develop consensus statements by synthesizing the current literature and leveraging clinical expertise. The review encompassed long-term anti-osteoporosis medication goals, first-line treatments for individuals at very high fracture risk, and the strategic integration of anabolic and anti resorptive agents in sequential therapy approaches. Results: The panelists reached a consensus on 12 statements. Key recommendations included advocating for anabolic agents as the first-line treatment for individuals at very high fracture risk and transitioning to anti resorptive agents following the completion of anabolic therapy. Anabolic therapy remains an option for in dividuals experiencing new fractures or persistent high fracture risk despite antiresorptive treatment. In cases of inadequate response, the consensus recommended considering a switch to more potent medications. The consensus also addressed the management of medication-related complications, proposing alternatives instead of discontinuation of treatment. Conclusions This consensus provides a comprehensive, cost-effective strategy for fracture prevention with an emphasis on shared decision-making and the incorporation of country-specific case management systems, such as fracture liaison services. It serves as a valuable guide for healthcare professionals in the Asia-Pacific region, contributing to the ongoing evolution of osteoporosis management.

OBJECTIVES: To analyze the gross pathological data of sudden cardiac death (SCD) with different causes, to provide data support for the identification of sudden cardiac death with unknown causes. METHODS: A total of 167 adult SCD cases in the archive of the Forensic Expertise Institute of Nanjing Medical University from 2010 to 2020 were collected. The gross pathological data of SCD cases were summarized and the characteristics of different causes of death were statistically analyzed. RESULTS: The ratio of male to female SCD cases was 3.4∶1. Coronary heart disease was the leading cause of SCD, and mainly distributed in people over 40 years old. SCD caused by myocarditis was mainly distributed in young people and the mean age of death was (34.00±9.55) years. By analyzing the differences in cardiac pathological parameters of SCD with different causes, it was found that the aortic valve circumference was significantly dilated in the SCD caused by aortic aneurysm or dissection (P<0.05). The heart weight of SCD caused by aortic aneurysm or dissection and combined factors was greater, and both pulmonary and tricuspid valvular rings were dilated in the SCD caused by combined factors in adult males (P<0.05). CONCLUSIONS Various gross pathological measures of SCD with different causes are different, which has reference value in the cause of death identification of SCD.

Objective To evaluate the safety and efficacy of intravascular lithotripsy(IVL)in the treatment of coronary artery calcification lesions.Methods A total of 53 patients who underwent endovascular imaging guided treatment of coronary artery calcified lesions with either IVL or cutting balloon(CB)at the Affiliated Hospital of Jining Medical College from January 2023 to July 2023 were retrospectively analysed(IVL:n=18,CB:n=35)were retrospectively analysed to compare the technique,clinical success rate,major adverse cardiovascular events(MACE)and readmission for cardiovascular events in patients followed during hospitalisation and 1 month after the procedure.Results Clinical success rates were identical in the IVL and CB groups(100.0％vs.100.0％,P＞0.999),the minimum lumen area of lesions was similar in the VL and CB groups[(1.7±0.4)mm2 vs.(1.7±0.5 mm2),P=0.628].And there was a statistically significant difference in the overall mean lesion length between the IVL and CB groups[(28.4±9.6)mm vs.(20.9±8.6)mm,P=0.008].During the procedure,there were no complications such as aneurysm,thrombus,or emergency vessel closure.There was a statistically significant difference in the overall mean value of residual stenosis between the IVL and CB groups[(1.7±1.7)％vs.(6.9±2.0)％,P=0.049].There were no MACE in either group during hospitalisation or at the one-month follow-up(0 vs.0,P＞0.999),and 3 patients in the CB group were readmitted for angina pectoris(0 vs.8.6％,P=0.543),with no significant difference in readmission rates between the two groups.Conclusions The technique of intravascular lithotripsy is safe and effective in the treatment of coronary artery calcification lesions.

Objective:To explore the characteristics of gut microbiota in the preoperative, short-term postoperative and long-term postoperative period at (15.61±4.51) months in children with ventricular septal defect (VSD) of congenital heart disease (CHD) treated with cardiopulmonary bypass (CPB).Methods:A prospective study was conducted.In Guangzhou Women and Children′s Medical Center, 13 patients with VSD who were scheduled for CPB and additional 10 age- and gender-matched healthy infants as pre-CPB control group from January 2021 to January 2022 were enrolled.Fecal samples were collected at pre- and early post-CPB.Meanwhile, 18 gender- and CHD diagnosis and operation-matched patients at (15.61±4.51) months after CPB and 8 healthy age- and gender-matched children as long-term control group after CPB were also enrolled, and fecal samples were collected.16S rRNA sequencing of fecal samples from all subjects were performed and comparing the differences in gut microbiota between two groups via comparing alpha and beta diversity, parameter test or nonparametric test, and LEfSe analysis.Results:Compared with those of pre-CPB control group, there was a significant difference in the composition of gut microbiota in the preoperative period of VSD children, with significantly increased abundances of Enterobacteriaceae and Shigella, and decreased abundance of Bifidobacterium (all P<0.05). The diversity of gut microbiota was comparable in VSD children before CPB and in the short period time after CPB (all P>0.05), except for the abundances of Clostridium and Streptococcus (all P<0.05), and there was no significant difference in the relative abundances of other highly abundant gut bacteria between the two periods (all P>0.05). Compared with that in VSD children in the short period time after CPB, the abundances of short-chain fatty acids-producing microbes were significantly higher at (15.61±4.51) months postoperatively (all P<0.05), and the gut bacteria profile was similar to that of the long-term control group after CPB (all P>0.05). Conclusions:Gut microbiota imbalance exists in VSD children before CPB.The gut microbiota profile is not influenced by CPB, which returns normal at (15.61±4.51) months postoperatively.

Abstract: Objective　To analyze the laboratory indexes of patients infected with malaria patients and COVID-19, so as to provide reliable evidence for the diagnosis of mixed infection of both. Methods　The routine clinical laboratory items such as routine blood, biochemistry and lymphocyte subsets were tested in three cases of COVID-19 complicated with falciparum malaria who admitted to Guangzhou Eighth People's Hospital Affiliated to Guangzhou Medical University from July to December 2020 were tested. Laboratory data were stage-wise analyzed in conjunction with changes in the course of disease. Results　Three patients confirmed COVID-19 infection recruited all had malaria infection history. Fever, headache, and other symptoms emerged on the 4rd to 11th day after admission. Malaria parasite was detected by malaria parasite antigen testing and blood smear testing, and all three patients had re-ignition of malaria after being confirmed COVID-19 infection. In the early stage of malaria relapse, lymphocytes decreased, CRP and SAA increased, and gradually returned to normal level after antimalarial treatment. Interestingly, we only found one patient at the initial stage of malaria detection showed PLT decreased, no other unnormal changes in other routine blood results (WBC, ESO) and liver function results (ALT, AST, GGT, TBIL, DBIL, CG) were found from the beginning to end course of the disease. Conclusion　COVID-19 infection may promote the resurgence of malaria, so the relapse of malaria should be monitored especially for the patient with malaria infection history who begin to develop fever and other symptoms a few days after the diagnosis of COVID-19. The inflammatory indicators would be worth able as an auxiliary judgment basis for the effective treatment of the two combined infection.
