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 Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

Ankylosing spondylitis (AS) combined with spinal fractures with thoracic and lumbar fracture as the most common type shows characteristics of unstable fracture, high incidence of nerve injury, high mortality and high disability rate. The diagnosis may be missed because it is mostly caused by low-energy injury, when spinal rigidity and osteoporosis have a great impact on the accuracy of imaging examination. At the same time, the treatment choices are controversial, with no relevant specifications. Non-operative treatments can easily lead to bone nonunion, pseudoarthrosis and delayed nerve injury, while surgeries may be failed due to internal fixation failure. At present, there are no evidence-based guidelines for the diagnosis and treatment of AS combined with thoracic and lumbar fracture. In this context, the Spinal Trauma Academic Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate the Clinical guideline for the diagnosis and treatment of adult ankylosing spondylitis combined with thoracolumbar fracture ( version 2023) by following the principles of evidence-based medicine and systematically review related literatures. Ten recommendations on the diagnosis, imaging evaluation, classification and treatment of AS combined with thoracic and lumbar fracture were put forward, aiming to standardize the clinical diagnosis and treatment of such disorder.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

OBJECTIVE: To compare the clinical efficacy and its effect on serum levels of tumor necrosis factor α(TNF-α), interleukin 1β(IL-1β), interleukin 6 (IL-6) and prostaglandin E₂ (PGE₂) between short needling (close-to-bone needling) and conventional acupuncture for knee osteoarthritis (KOA) with blood stasis obstruction. METHODS: A total of 68 KOA patients with blood stasis obstruction were randomized into a short needling group (34 cases, 3 cases dropped off) and a conventional acupuncture group (34 cases, 3 cases dropped off). The same acupoints (Dubi [ST 35], Neixiyan [EX-LE 4], Binzhong [Extra], Liangqiu [ST 34], etc. on the affected side) were selected in the two groups. In the short needling group, short needling technique was adopted, the needles were slowly inserted and the needle bodies were shaken, thus gradually penetrated to the bone. In the conventional acupuncture group, conventional acupuncture was adopted, the needles were penetrated to the muscle. After qi-arrival, Dubi (ST 35) and Neixiyan (EX-LE 4), Zusanli (ST 36) and Liangqiu (ST 34) were connected with CMNS6-1 electronic acupuncture instrument, with disperse-dense wave, 2 Hz/10 Hz in frequency, the current intensity was based on patients' feeling, the needles were retained for 30 min, at the same time, the knee joint was irradiated for 30 min with a special electromagnetic wave apparatus in the two groups. Once every other day, 3 times a week for 4 weeks. Before and after treatment, the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score, knee joint pain visual analogue scale (VAS) score, inflammatory response related indexes (serum TNF-a, IL-1β, IL-6 and PGE₂) and knee joint ultrasound were observed，and the clinical effect was evaluated in the two groups. RESULTS: After treatment，the pain, stiffness, function scores and total scores of WOMAC were decreased as compared with those before treatment in the two groups (P<0.05), except for the pain score, the changes of above scores in the short needling group were greater than the conventional acupuncture group (P<0.05). After treatment, the VAS scores, serum levels of TNF-a, IL-1β, IL-6, PGE₂ and knee joint synovium thickness, intra-articular effusion were decreased as compared with those before treatment in the two groups (P<0.05), the levels of TNF-a, IL-1β, IL-6 in the short needling group were lower than the conventional acupuncture group (P<0.05). The total effective rate in the short needling group was 87.1% (27/31), which was superior to 83.9% (26/31) in the conventional acupuncture group (P<0.05). CONCLUSION Short needling could improve the knee joint function, relieve the pain and inflammatory response, improve the knee joint synovium inflammatory response, reduce the knee joint intra-articular effusion for KOA patients, its effect is better than conventional acupuncture.

Objective:To explore the effects of cold ischemia time (CIT) and donor age upon postoperative and long-term follow-ups of heart transplantation.Methods:A total of 761 patients underwent orthotopic heart transplantation from 2004 to 2018. According to the length of CIT, they were divided into group of >4 hours (n=502) and group of <4 hours (n=259). Each group was further divided into two subgroups according to the age of donors: group of <40 years and group of <40 years. The basic profiles of recipients and donors were recorded, including applying mechanical assistance during and after operation, postoperative mortality and follow-up survival rate.Results:The average age of donors was (31.1±8.6)(5-58) years and the average CIT (5.3±2.0)(1.0-12.0) hours. No significant difference existed in hospital mortality between CIT groups (3.5% vs 5.6%, P=0.22). In subgroup analysis, there was a significant increase (4.3% vs 12.0%, P=0.01) in subgroup with CIT >4 hours and higher donor age. No significant difference existed in the number of patients using mechanical assistance during or after operation. During follow-ups, no significant difference existed in survival rate between CIT groups ( P=0.97) or survival rate among subgroups. Conclusions:Long CIT has a more significant effect on postoperative mortality of heart donors. However, it does not significantly increase the proportion of mechanical assistance, follow-up mortality and the incidence of cardiac allograft vasculopathy.

Objective    To analyze the risk factors of new-onset postoperative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG). Methods    From September 2011 to October 2013, 1 614 consecutive patients underwent elective coronary artery bypass grafting in Fuwai Hospital. There were 1 281 males and 333 females at average age of 60.3±8.4 years. Holter data recorded for 5 days after operation were collected and analyzed. The risk factors associated with POAF were assessed according to the baseline and intraoperative data, and the positive variables were stratified. Results    A total of 314 patients (19.5%) developed new-onset POAF. The rate of POAF was elevating with the increase of age (P<0.001). Conclusion    Age was an independent risk factor for POAF in patients undergoing elective CABG alone.

The effects of catechin on inflammatory response of BV-2 cells were investigated using the lipopolysaccharide (LPS) model. BV-2 cells were incubated with LPS (1 mg·L^-1) for 12 h in the microglia inflammatory model in vitro. After catechin and LPS co-incubation for 12 h, MTT, ELISA and Western blot were used to detect cell viability, cytokines, cell migration and protein expression. In addition, transwell assay was conducted to investigate the effect of catechin on cell chemokaxis. Catechin did not show any cytotoxicity effect on BV-2 cells, but reversed the change in cell morphology and inhibited the release of TNF-α and IL-1β, cell chemotaxis and phosphorylation of NF-κB/p65. In conclusion, Catechin could inhibit the LPS-induced inflammatory response in BV-2 cells.

Objective: To describe the incidence,clinical characteristics,therapy strategy and outcomes of spontaneous coronary artery dissection based on single-center experience in China.Methods:We performed retrospective case-identification study in 16 526 patients underwent coronary angiography in Zhongshan Hospital of Fudan University between March 2015 to December 2016,and identified 17 patients with spontaneous coronary artery dissection.Risk factors,clinical features,angiographic features,therapy strategy,and clinical outcomes were analyzed.Results:The incidence of SCAD was 17 of 16 526(1.03/1 000).The mean age was(49.06 ± 10.73)years old(range:26-67 years old).In these 17 cases,4 cases were males,and others were females.Females constituted 13 of 17(76.5%).All SCAD patients presented with acute coronary syndrome,including 10 patients with acute ST-elevated myocardial infarction,3 patients with acute non-ST-elevated myocardial infarction and 4 patients with unstable angina.Twenty dissection sites were identified in 17 SCAD patients. Dissection was predominantly located at the left descending artery(50%)and the right coronary artery(35%).All lesions fell into three types:type Ⅰ(n=5),type Ⅱ A(n= 7),type ⅡB(n= 6),and type Ⅲ(n= 2).The TIMI flow in the distal segment of the coronary dissection was classified as follows:class 0(n=4),class 1(n=2),class 3(n=14).Conservative medical treatment was adopted by 7 of 17(41.1%)patients,and percutaneous transluminal coronary angioplasty(PTCA)in 1 of 17(5.9%)patients.No recurrent angina and other cardiovascular events was observed during clinical follow up. Percutaneous coronary intervention(PCI)was performed in 9 of 17(52.9%)patients,and the mean number of deployed stent was(2.44 ± 1.13).Intramural hematoma was extended during PCI in 5 of 9(55.6%)patients,resulting in new-onset nonfatal myocardial infarction in one patient and cardiac death in another patient.Conclusions:SCAD should be considered in young and middle-aged female patients presented with acute coronary syndrome,especially in those with few coronary risk factors. Interventional cardiologist should be familiar with the angiographic characteristics of SCAD,and turn to intravascular ultrasound if necessary.Conservative treatment should be the first choice in most patients with SCAD,while PCI intervention could be considered in high risk patients.Be caution to prevent interventional complications such as dissection expansion in the patients with high-risk.
