OBJECTIVE To explore the significance of pharmaceutical care through the diagnosis and treatment of a patient with exogenous insulin autoimmune syndrome （EIAS）， combined with the analysis of literature reports. METHODS Clinical pharmacist participated in the diagnosis and treatment process of one case of EIAS. Based on the characteristics of the patient’s condition， the pharmacist provided medication suggestions and formulated pharmaceutical monitoring measures. At the same time， the pharmacist searched for relevant literature on insulin autoimmune syndrome （IAS） and EIAS， extracted data （gender， age， occurrence time， laboratory tests， clinical symptoms， intervention and outcome）， and conducted analysis. RESULTS Based on the patient’s medication information in the past 3 years， clinical pharmacist determined that the EIAS was likely caused by insulin aspartate 30. The clinician adopted the clinical pharmacist’s suggestion to discontinue insulin and switch to oral hypoglycemic drugs. The patient improved after treatment. The literature analysis showed that among the 257 patients with IAS reported， 212 cases were caused by drugs； among them， 23 cases were caused by lipoic acid， and 56 cases were caused by exogenous insulin. There were no significant differences in age， glycosylated hemoglobin， and body mass index between the two groups. The lowest blood glucose level in the lipoic acid group was significantly lower than that in the exogenous insulin group （P＜0.05）. The proportion of females and the proportion of fasting insulin ≥ 1 000 μU/mL were significantly higher in the lipoic acid group than in the exogenous insulin group （P＜0.05）. CONCLUSIONS Compared with EIAS， lipoic acid-induced IAS usually causes more severe hypoglycemia， and the fasting insulin level is usually higher than 1 000 μU/mL， which is more common in female patients. The participation of clinical pharmacists in the diagnosis and treatment of EIAS can help improve the diagnosis and treatment level of similar rare diseases and ensure the safety of patients’ medication.

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.

[摘 要] 目的：探讨人参皂苷Rb1（Gn-Rb1）对肝细胞癌（HCC）HepG2细胞氧死亡的影响及其可能的分子机制。方法：采用生物信息学方法分析氧死亡的关键基因PGAM5表达对HCC患者生存期的影响。选取辽宁省肿瘤医院收治的8例HCC患者的HCC组织与癌旁组织，通过WB法及qPCR检测氧死亡相关基因蛋白与mRNA的表达情况。将HepG2细胞随机分为对照组与Gn-Rb1组（予以200 μmol/L Gn-Rb1干预），采用细胞克隆形成实验、划痕愈合实验分别检测Gn-Rb1对HepG2细胞的集落形成能力、迁移能力的影响，ELISA检测对细胞ROS生成水平的影响，微板法检测对细胞LDH释放水平的影响；WB法、qPCR法检测Gn-Rb1对HepG2氧死亡关键基因蛋白质与mRNA水平表达的影响。结果：生物信息学分析发现，PGAM5高表达肝癌患者总生存时间较低表达患者更长（P<0.05）。在临床HCC组织与癌旁组织样本中发现，相较于癌旁组织，在蛋白质与mRNA水平上，肿瘤组织KEAP1与PGAM5表达显著降低，NRF2表达显著升高（均P<0.01），p-AIFM1蛋白水平显著升高（P<0.05）。对HepG2细胞予以200 μmol/L Gn-Rb1干预后，相较于对照组，Gn-Rb1组HepG2细胞的迁移能力与集落形成能力显著降低（均P<0.01），而LDH水平显著升高（P<0.05）；相比于对照组，在mRNA和蛋白质水平上，Gn-Rb1组细胞中KEAP1、PGAM5表达均显著升高而NRF2表达均显著降低（均P<0.05），p-AIFM1蛋白表达显著降低（P<0.01）。结论：HCC组织中氧死亡被抑制，而Gn-Rb1能够通过调控KEAP1/PGAM5/AIFM1通路促进HepG2细胞氧死亡的发生，抑制细胞增殖和迁移能力。

ObjectiveTo explore the effect of grain-sized moxibustion at "Zhongwan （RN12）" "Tianshu （ST25）" and "Shangjuxu （ST37）" on the colon tissue of mice with ulcerative colitis （UC）， and to analyze the potential mechanism. MethodsForty C57BL/6 male mice were randomly divided into blank group， model group， moxibustion group and mesalazine group， with 10 mice in each group. In all the groups except for the blank group， UC mouse model was prepared by freely drinking 3% sodium dextran sulfate solution. After successful modeling， the moxibustion group was treated with grain-sized moxibustion at Zhongwan， Tianshu and Shangjuxu ， 3 cones per acupoint， 30 s of each cone. The mesalazine group was given 300 mg/kg of mesalazine enteric-coated tablet solution by gavage. The blank group and the model group were only fixed by grasping without any intervention. Each group was intervened once a day for 7 consecutive days. The general condition of mice in each group was observed， and the disease activity index （DAI） score was evaluated. The colon length， intestinal weight and colon mucosal injury score were detected. The contents of serum intercellular adhesion molecule-1 （ICAM-1）， interleukin-6 （IL-6） and tumor necrosis factor-α （TNF-α） were detected by ELISA. The pathological changes of colon tissue were observed by HE staining. The mRNA and protein expressions of non-receptor tyrosine protein kinase 2 （JAK2）， signal transducer and activator of transcription 3 （STAT3） and suppressor of cytokine signaling 3 （SOCS3） in colon tissue of mice were detected by real-time fluorescence quantitative PCR and immunohistochemistry， respectively. The mean fluorescence intensity of JAK2 and SOCS3 in colon tissue of mice was detected by immunofluorescence double staining. ResultsCompared to the blank group， the mice in the model group had unclean perianal area， unformed stool， destroyed colonic mucosal morphology， shortened body weight and colon length， increased DAI score， intestinal weight index， colonic mucosal injury and pathological score， serum ICAM-1， IL-6 and TNF-α levels， increased mRNA and protein expression of JAK2 and STAT3 in colon tissue， and decreased mRNA and protein expression of SOCS3 （P＜0.01）. Compared to those in the model group， the perianal area of mice in the moxibustion group and the mesalazine group was improved， and the colonic mucosal morphology was more complete； body weight and colon length increased， while DAI score， intestinal weight index， colonic mucosal injury and pathological score， serum ICAM-1， IL-6 and TNF-α levels decreased， with decreased mRNA and protein expression of JAK2 and STAT3 in colon tissue， and increased SOCS3 mRNA and protein expression （ P＜0.01 or P＜0.05 ）. There was no significant difference in any index between the moxibustion group and the mesalazine group. ConclusionGrain-sized moxibustion at "Zhongwan"， "Tianshu" and "Shangjuxu" can improve the damage of colon mucosa in UC model mice， and the mechanism may be related to the key factors regulating JAK2 / STAT3 signaling pathway based on SOCS3.

Objectives:To investigate the feasibility of using bedside echocardiography on the evaluation of potential donors with different causes of brain death for adult heart transplantation. Methods:Bedside echocardiographic and clinical data of consecutive potential donors for adult heart transplantation evaluated by the team of our institution from February 2018 to December 2020 were retrospectively analyzed.Based on different causes of brain death,the potential donors were divided into stroke(ischemic or hemorrhagic,n=398)and non-stroke(head trauma,brain tumor,anoxia,n=272)groups.The clinical and echocardiographic features were compared between the two groups.A total of 350 donors were assigned to our hospital by the China Organ Transplant Response System and met the inclusion criteria for donor selection.There were 195 cases in the stroke group and 155 in the non-stroke group.Retrieval operations were performed and the retrieval rate of hearts for transplantation in stroke donors was compared to that in non-stroke donors. Results:(1)Among the 670 potential heart donors,compared with the non-stroke group,donors in the stroke group were significantly older,had higher body mass index,larger left ventricular end-diastolic diameter,thicker interventricular septum,higher rates of echocardiographic abnormalities,higher prevalence of hypertension(all P<0.001).Among the 670 potential heart donors,17.5%(117 cases)did not meet the echo selection criteria,the common causes were left ventricular hypertrophy(59 cases,50.4%),left ventricular ejection fraction<50%(27 cases,23.1%),wall motion abnormalities(21 cases,17.9%),and left ventricular dilation(14 cases,12.0%).(2)Among the 350 donors who had met the selection criteria and assigned to our hospital by the China Organ Transplant Response System and underwent retrieval operation,70.3%(246 cases)were successfully procured,110 cases(44.7%)in the stroke group and 136 cases(55.3%)in the non-stroke group.The retrieval rate of stroke donors(110/195,56.4%)was lower compared with that of non-stroke(136/155,87.7%,P<0.001),104 cases(29.7%)were not retrieved,and the leading cause of unsuccessful organ retrieval was the occlusion of at least one major coronary artery(91 cases,87.5%). Conclusions:Bedside echocardiography is of great value as a screening tool for cardiac donors.Cardiac structures of the potential donor with stroke as the cause of brain death were different from those with non-stroke causes.The retrieval rate of stroke donors was lower than that of non-stroke donors,even if the initial criteria for donor selection were fulfilled.

Aim To explore the effect of quercetin(Que)on ferroptosis and the potential mechanisms in an Erastin-induced ferroptosis model in chondrocytes.Methods A model of Erastin-induced ferroptosis was established in C28/I2 chondrocytes.Cells were treated with different concentrations of Que.Cell viability and cytotoxicity were assessed by MTT and LDH assays.The expression levels of Prdx6 and ferroptosis-related proteins ACSL4 and GPX4 in chondrocytes were deter-mined by Western blot.Lipid ROS production in chon-drocytes was measured by flow cytometry,while the changes in mitochondrial membrane potential were de-tected by RH123 staining.Prdx6 mRNA expression in chondrocytes was quantified by RT-qPCR.The chan-ges in the expression of the ferroptosis-related proteins ACSL4 and GPX4 were detected by immunofluores-cence staining.Results Compared to the Erastin-in-duced ferroptosis model group,Que significantly im-proved the viability of C28/I2 chondrocytes and re-duced cell cytotoxicity.It decreased the expression of the ferroptosis-related protein ACSL4 and increased the expression of GPX4.Que also inhibited the production of lipid ROS in chondrocytes and strengthened their mitochondrial membrane potential.In addition,the ex-pression of Prdx6 was significantly reduced in the Eras-tin group compared to the control group,while Que treatment upregulated the expression of Prdx6.Mean-while,the inhibitory effect of Que on chondrocyte fer-roptosis was reduced by the use of MJ33,an inhibitor of Prdx6.Conclusion Que can inhibit Erastin-induced ferroptosis of C28/I2 chondrocytes,possibly by upregu-lating Prdx6,and thus play a protective role in chon-drocytes.

Objective To observe the efficacy of gray-scale ultrasound-based radiomics for differentiating peripheral pulmonary adenocarcinoma and squamous cell carcinoma.Methods Data of 88 patients with single peripheral lung adenocarcinoma and 58 patients with single peripheral lung squamous cell carcinoma proved pathologically with puncture biopsy and clearly visualized with lung ultrasound were retrospectively analyzed.The patients were divided into training set(n=103)and test set(n=43)at the ratio of 7:3.Based on gray-scale ultrasound of training set,radiomics features associated with differential diagnosis of peripheral lung adenocarcinoma and lung squamous cell carcinoma were extracted and screened.Using 4 different classifiers,including support vector machine(SVM),linear discriminant analysis(LDA),logistic regression(LR)and the least absolute shrinkage and selection operator combined with logistic regression(LASSO-LR),4 corresponding radiomics models were obtained,and the relative best models were selected according to their performances under 10-fold cross validation.The receiver operating characteristic curves were drawn,the areas under the curve(AUC)were calculated to evaluate the differentiating efficacy of each model,and DeLong test was used for the comparison.The differentiating accuracy of models were obtained under the best cutoff value with the maximum Youden index.Results The AUC of SVM,LDA,LR and LASSO-LR radiomics models for differentiating peripheral lung adenocarcinoma and lung squamous carcinoma in test set was 0.864,0.867,0.880 and 0.844,respectively,and no significant difference was found among 4 models(all P＞0.05).Under the best cutoff value of each model,the corresponding accuracy of SVM,LDA,LR and LASSO-LR radiomics models for differentiating peripheral lung adenocarcinoma and lung squamous cell carcinoma was 86.05％,83.72％,88.37％and 86.05％,respectively.Conclusion Radiomics models based on gray-scale ultrasound could be used to differentiate peripheral lung adenocarcinoma and lung squamous cell carcinoma.

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.
