Objective: To investigate the clinical symptoms, laboratory tests, and treatment strategies of a case of fetal/neonatal alloimmune thrombocytopenia (FNAIT) complicated with piperacillin drug antibody. Methods: The platelet antibodies in the mother were screened and identified by ELISA. The HLA antigens of the newborn were genotyped through PCR-SSO, while the specificity of HLA antibodies in the mother was determined using a Single Antigen kit. The drug antibody was detected by a piperacillin kit. Results: Maternal antibodies against paternally-derived platelet antigens were detected. The HLA genotypes of the newborn were identified as HLA A 33∶03 and HLA B 58∶01. The mother exhibited strong positive antibodies against the specific platelet antigens of the newborn, namely anti-HLA-A33 and anti-HLA-B58 antibodies. The piperacillin antibody was detected in the newborn. Following treatment of continuous intravenous immunoglobulin (IVIG), platelet transfusions, red blood cell transfusions and discontinuation of piperacillin treatment, the platelet count and hemoglobin levels increased in the newborn. Conclusion: The newborn in this case was diagnosed with FNAIT complicated by the presence of anti-HLA-A33 and anti-HLA-B58 antibodies, as well as drug-induced hemolytic anemia caused by piperacillin drug antibody. The condition is more complicated under the influence of dual immune antibodies. Laboratory detection techniques such as platelet antibody and drug antibody tests can assist in early clinical diagnosis. At the same time, more active drug and blood transfusion treatments should be given in clinical practice to improve the prognosis.

OBJECTIVE To investigate the effects of alirocumab combined with atorvastatin on clinical efficacy and safety of patients with acute coronary syndrome （ACS） who underwent percutaneous coronary intervention （PCI）. METHODS A total of 207 patients with ACS who underwent PCI in our hospital from January 2021 to December 2023 were randomly divided into alirocumab group， ezetimibe group and control group， with 69 cases in each group. All patients received routine thrombosis prevention and antihypertensive treatment after PCI. On this basis， patients in the control group were treated with atorvastatin （20 mg/time， once a day）； patients in the ezetimibe group were treated with ezetimibe （10 mg/time， once a day） + atorvastatin （20 mg/time， once a day）； patients in the alirocumab group were treated with alirocumab （75 mg/time， once every 2 weeks） + atorvastatin （20 mg/time， once a day）. All patients in the three groups were treated for 8 weeks and followed up for another 6 months after treatment. The levels of cardiac function and lipid metabolism indices before and after treatment， as well as the occurrence of major adverse cardiovascular event （MACE） and other adverse drug reaction （ADR） during the follow-up period were compared among the three groups. RESULTS After treatment for 8 weeks， the levels of cardiac function and lipid metabolism indices in the three groups were significantly improved compared with those before treatment （P＜0.05）. Compared with the control group and ezetimibe group， the left ventricular ejection fraction in the alirocumab group was significantly increased， and the left ventricular end-diastolic diameter （LVEDD） was significantly shortened （P＜0.05）. Compared with control group， LVEDD of ezetimibe group was significantly shortened （P＜0.05）， the levels of total cholesterol， triglyceride and low-density lipoprotein cholesterol in the alirocumab group and ezetimibe group were significantly decreased （P＜0.05）. During the follow-up period， there was no significant difference in the total incidence of MACE and the total incidence of other ADR such as headache and abdominal pain among the three groups （P＞0.05）. CONCLUSIONS Alirocumab combined with atorvastatin can significantly improve cardiac function and regulate lipid metabolism indices in patients with ACS after PCI without increasing the risk of MACE or other ADR.

Objective To assess the effectiveness of various traditional Chinese medicine(TCM)compound prescription combined with conventional western medications for treating coronary heart disease with depression through network Meta-analysis.Methods Search CNKI,Wanfang data,VIP,SinoMed,PubMed,Web of Science,Embase,Cochrane Library by computer.Randomized controlled trials of TCM compound prescription combined with conventional Western medications in the treatment of coronary heart disease with depression were collected from established to March 17,2024.The quality of the literatures was assessed using RoB 2.0 software,and network Meta-analysis was conducted using Stata 16.0 software.Results A total of 41 iteratures were included,involving 7 efficacy combinations.The results of the analysis showed that the highest clinical efficacy was found in the heat-clearing and tranquilizing category of TCM compound prescription+conventional western medicine[surface under the cumulative ranking curve(SUCRA)=79.4%],which significantly improved Hamilton depression scale scores(SUCRA=84.4%).The regulating qi type of TCM compound prescription+conventional western medicine significantly improved TCM symptoms(SUCRA=68.4%)and depression-related symptoms(SUCRA=94.8%).Conclusion Compared to using conventional Western medicines alone,the combined application of TCM compound prescription proves to be more effective,with regulating qi being crucial for treating this condition.

Objective To investigate the correlation between novel bone metabolism markers and the degree of aortic calcification as well as cardiovascular event risk in elderly patients treated by PD.Methods A prospective trial was conducted on 230 elderly patients receiving continuous am-bulatory PD in our department from February 2022 to February 2024.According to the occur-rence of cardiovascular events during dialysis treatment,they were divided into a cardiovascular event group(n=92)and a control group(n=138).Relevant clinical data were collected,aortic calcification was assessed using AAC scores,and serum levels of bone metabolism markers,inclu-ding osteoprotegerin,TRACP,and PINP were measured.Results The serum levels of osteoprote-gerin,TRACP and PINP were significantly higher in the cardiovascular event group than the con-trol group(P＜0.01).The cardiovascular event group had obviously severe calcification and higher AAC score than the control group(P＜0.01).The serum levels of the three bone metabolism markers were notably higher in the patients with severe calcification than those with moderate calcification,followed by mild calcification in turn(P＜0.01).Spearman correlation analysis indi-cated that the levels of the three indicators were positively correlated with the degree of aortic cal-cification in elderly PD patients(r=0.465,P=0.000;r=0.396,P=0.000;r=0.434,P=0.000).Multivariate logistic regression analysis showed that these three indicators were risk factors for cardiovascular events in elderly PD patients(P＜0.01).Conclusion The three bone metabolism markers are significantly correlated with aortic calcification severity and cardiovascular event risk in elderly PD patients.Monitoring these marker levels may be helpful for the assessment and man-agement of cardiovascular risk.

OBJECTIVE To evaluate the short-term efficacy of single-session microwave ablation for benign thyroid nodule.METHODS Patients with benign thyroid nodules treated by microwave ablation between June 2019 and December 2022 at the Department of Otolaryngology Head and Neck Surgery,the First Affiliated Hospital of Xi'an Jiaotong University,were included for analysis.Thyroid function was tested 1 month after treatment,and ultrasound and thyroid function were performed 3 months,6 months and 1 year after treatment.Volume reduction rates(VRR)of nodules were calculated.Data of the last follow-up within 1 year were included for analysis.Variables including gender,age,whether Hashimoto's thyroiditis was present,longitudinal diameter of nodules,solid volume of nodules were included for univariate and multivariate analysis.RESULTS A total of 151 patients with 163 nodules were included.The perioperative complication rate was 1.99%(3/151).The VRR at half year after treatment was(79.58±17.70)%,and the success rate at half year after treatment was 93.43%(128/137).The VRR of at 1year after treatment was(81.24±24.29)%.The 1-year treatment success rate was 92.77%(77/83).Univariate and multivariate analysis showed that nodular solid volume and age were independent factors affecting VRR after ablation.Regression coefficient of age and solid volume was 0.34(P<0.05)and-0.47(P<0.05),respectively.For every 1 cm3 increase in solid volume,1-year VRR(%)decreased by 0.47.Regression equation:1-year VRR=68.92+0.34×age-0.47×solid volume.Serum FT4 gradually decreased and the thyroid stimulating hormone(TSH)gradually increased within 6 months after ablation,and the differences were statistically significant(P<0.05).After 6 months,serum FT4 gradually recovered to the normal level and TSH gradually recovered.However,TSH still did not reach the preoperative level one year after ablation.FT3 decreased gradually after treatment,but there was no significant difference between the values at each time point(P=0.40).After the ablation of thyroid nodule,the mean value of thyroid function index fluctuated,but all of them were within the normal reference range.CONCLUSION Microwave ablation is a safe and effective treatment method for benign thyroid nodules,with an overall success rate of over 90%.Solid nodule volume and age are independent factors affecting the microwave ablation effect of benign thyroid nodules.

Objective To investigate the effect of ultrasound-guided erector spinae plane block(ESPB)on early postoperative respiratory function and inflammatory cytokines in patients with multiple rib fractures(MRFs).Methods Fifty-eight patients who underwent MRFs surgery,42 males and 16 females,aged 18-64 years,BMI 18.5-30.0 kg/m2,ASA physical status Ⅰ or Ⅱ,were selected from February 2019 to December 2021.The patients were divided into two groups using random number method:ESPB combined with general anesthesia group(group E)and general anesthesia alone group(group G),29 pa-tients in each group.All the patients in group E underwent ultrasound-guided ESPB in the lateral decubitus position after general anesthesia induction,and 0.5％ropivacaine 0.4 ml/kg was administered.Forced vital capacity(FVC),arterial blood gas analysis,VAS pain scores at rest and cough were recorded before anes-thesia induction,at discharge from PACU,24 and 48 hours after operation.The number of effective PCIA compressions during 0-24 hours and 24-48 hours after surgery and the number of rescue analgesia were re-corded.The concentrations of IL-6 and TNF-α were recorded before anesthesia induction,24 and 48 hours after operation.Results Compared with group G,the FVC was significantly higher,and the VAS score and PaCO2 were significantly lower in group E at discharge from PACU,24 and 48 hours after operation(P＜0.05).The number of effective PCIA compressions during 0-24 hours and 24-48 hours after surgery,the rate of rescue analgesia,the concentrations of IL-6 and TNF-α 24 and 48 hours after operation in group E were significantly lower than those in group G(P＜0.05).Conclusion Ultrasound-guided ESPB can pro-vide good postoperative analgesia,promote early postoperative recovery of respiratory function in patients with MRFs.

Pain is an uncomfortable and emotional experience associated with,or similar to,real or po-tential tissue damage.However,far from being a purely physiological sensation,pain involves complex emo-tional and neuromodulatory mechanisms.The pain neural circuit is a complex biological system,covering the multi-level structure of the central nervous system from peripheral neurons to the cerebral cortex,thalamus,a-mygdala and dorsal horn of the spinal cord,participating in the perception,conduction,and regulation of pain signals,involves multiple molecular and cellular interactions to build a comprehensive pain perception process.In recent years,the field of pain neural circuit research has used a variety of scientific and technological tools to provide the theoretical and technical support for the in-depth understanding and treatment of pain.This article aims to provide a comprehensive research status quo for the scholars in related fields and new ideas for clinical pain research and treatment by combing the application of different technologies in the study of pain neural circuits.
