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.

As interstitial collagen,type Ⅲ collagen(Col Ⅲ)does not express in normal glomeruli.However,in Col Ⅲ nephropathy,a large amount of Col Ⅲ deposit in the mesangial and subendothelial area of the glomeruli.IgA nephropathy with Col Ⅲ deposition was extremely rare.In this article,we reported two cases of such disease.After treating with immunosuppressive agents or traditional Chinese medicine decoction,the renal function of the two patients remained stable and the urinary protein levels reduced significantly.

Objective To investigate the effect of erector spinae plane block on postoperative delirium and cognitive function in elderly patients with lung cancer undergoing thoracoscopic radical surgery.Methods A total of 90 elderly patients with lung cancer underwent thoracoscopic radical surgery were selected and randomly divided into the control group and the observation group,with 45 cases in each group.The patients in the control group were given general anesthesia,while the patients in the observation group were given erector spinae plane block before general anesthesia.The vital signs at different time points,opioid dosage,number of analgesic pump compressions,incision pain visual analogue scale(VAS)score,cognitive function and postoperative delirium of patients between the two groups were compared.Results At the end of anesthesia,the mean arterial pressure(MAP)and heart rate of patients in the observation group were significantly lower than those in the control group(P<0.05).The dosage of remifentanil during operation,sufentanil during perioperative period and number of analgesia pumps compressions of patients in the observation group were significantly less than those in the control group(P<0.05).The incision pain VAS scores 6 hours,12 hours,24 hours and 48 hours after surgery of patients in the observation group were significantly lower than those in the control group(P<0.05).The scores of cognitive function 6 hours and 24 hours after surgery of patients in the observation group were significantly higher than those in the control group(P<0.05);and the incidence of delirium 6 hours and 24 hours after surgery in the control group was significantly higher than those in the observation group(P<0.05).Conclusion Erector spinae plane block can significantly relieve the perioperative pain of elderly patients with lung cancer undergoing thoracoscopic radical surgery,reduce the dosage of opioids and the incidence of postoperative delirium,improve the postoperative cognitive function of patients,which provides a new idea for reducing the incidence of postoperative mental diseases.

Objective To explore the effects of different CO2 pneumoperitoneum pressures during operation on delirium and cognitive function of elderly patients undergoing laparoscopic radical resection of rectal cancer.Methods A total of 92 elderly patients who underwent laparoscopic radical resection of rectal cancer were selected as the research subjects,and the patients were randomly divided into H group and L group,with 46 cases in each group.Patients in H group used CO2 pneumoperitoneum pressure of 15 mmHg during surgery,while patients in L group used CO2 pneumoperitoneum pressure of 11 mmHg during surgery.The cognitive function scores,postoperative delirium,blood gas analysis results,vital signs and adverse reactions during anesthesia awakening period of patients in the two groups were compared.Results The cognitive function scores 6 hours and 24 hours after surgery of patients in L group were significantly higher than those in H group(P<0.05).The incidences of delirium 6 hours and 24 hours after surgery in L group were significantly lower than those in H group(P<0.05).There was no statistically significant difference in mean arterial pressure(MAP),heart rate or pulse oxygen saturation(SpO2)before and after pneumoperitoneum of patients between the two groups(P>0.05).There were statistically significant differences in pH and partial pressure of carbon dioxide(PaCO2)at the end of pneumoperitoneum of patients between the two groups(P<0.05).The incidences of delayed awakening and agitation during the awakening period of patients in H group were significantly higher than those in L group(P<0.05).Conclusion For elderly patients undergoing laparoscopic radical resection of rectal cancer,CO2 pneumoperitoneum of 11 mmHg pressure has a smaller effect on postoperative cognitive function and a lower incidence of postoperative delirium and adverse reactions during the awakening period,which may be related to the level of PaCO2 in the blood of patients,and should be paid attention to.

Deficiencies in the clearance of peripheral amyloid β (Aβ) play a crucial role in the progression of Alzheimer's disease (AD). Previous studies have shown that the ability of blood monocytes to phagocytose Aβ is decreased in AD. However, the exact mechanism of Aβ clearance dysfunction in AD monocytes remains unclear. In the present study, we found that blood monocytes in AD mice exhibited decreases in energy metabolism, which was accompanied by cellular senescence, a senescence-associated secretory phenotype, and dysfunctional phagocytosis of Aβ. Improving energy metabolism rejuvenated monocytes and enhanced their ability to phagocytose Aβ in vivo and in vitro. Moreover, enhancing blood monocyte Aβ phagocytosis by improving energy metabolism alleviated brain Aβ deposition and neuroinflammation and eventually improved cognitive function in AD mice. This study reveals a new mechanism of impaired Aβ phagocytosis in monocytes and provides evidence that restoring their energy metabolism may be a novel therapeutic strategy for AD.

Anti-seizure medications (ASMs) are the main therapy for epilepsy.There are many kinds of ASMs with complex mechanism of action, so it is difficult for pharmacists to examine prescriptions.This paper put forward some suggestions on the indications, dosage forms/routes of administration, appropriateness of usage and dosage, combined medication and drug interaction, long-term prescription review, individual differences in pathophysiology of children, and drug selection when complicated with common epilepsy, for the reference of doctors and pharmacists.

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 fulfill the automatic radiolabeling of the norepinephrine transporter (NET) trancer 18F-meta-fluorobenzylguanidine (mFBG), and explore the 18F-mFBG PET/CT imaging effect of pheochromocytoma. Methods:On the basis of the chemical structure of mFBG, a spirocyclic iodonium ylide was used as the precursor to undergo a 3-step reaction sequence (radiofluorination, deprotection and neutralization) on AllinOne synthesis module. Purification by high performance liquid chromatography and formulation were conducted to generate 18F-mFBG. The corresponding quality control tests of 18F-mFBG product was performed. Afterwards, a postoperative patient with pheochromocytoma underwent 18F-mFBG PET/CT imaging. Results:The radiosynthesis was accomplished within 70 min, and 18F-mFBG was obtained in (17.8±2.4)% non-decay-corrected radiochemical yield ( n=5), with radiochemical purity >97% and molar activity >59.2 GBq/μmol. Sterility test, bacterial endotoxins test, abnormal toxicity test and the acetonitrile residue all met the requirements of Pharmacopoeia of the People′ s Republic of China (2020 Volume Ⅳ). The 18F-mFBG PET/CT imaging disclosed high uptake in pheochromocytoma and clear localization of lesions. Conclusions:The automatic radiolabeling of the NET targeted tracer 18F-mFBG is successfully realized by commercially available synthesis module, and the production quality meets all requirements for clinical translation. 18F-mFBG has a potential to image neuroendocrine lesions in clinical setting.
