Objective Bibliometric analysis software VOSviewer and CiteSpace were applied to analyze literatures related to acupuncture for myocardial Ischemia/Reperfusion(I/R)injury published in Chinese and English,to explore the status quo,dynamic trend and hot spots in the field,in order to provide reference for future research.Methods Based on the literature on acupuncture and moxibustion for myocardial I/R injury published in CNKI and Web of Science Core Collection database,VOSviewer and CiteSpace software were used to analyze literature publication trends,authors,institutions,countries,journals,keywords and citations,and draw graphs and tables to show the development status of the field and analyze the future development direction.Results Both Chinese and English literatures on the treatment of myocardial I/R injury by acupuncture and moxibustion show an increasing trend,which is one of the academic hotspots with great potential at present.In terms of Chinese literature,Yan Jie is the scholar who has published the most papers,and Hunan University of Traditional Chinese Medicine is the representative of the high production institution.The journal of Acupuncture Research has published the most papers.In terms of English literature,lu sheng-feng is the representative scholar with a high number of publications,Nanjing University of Chinese Medicine is the institution with the largest number of publications,and Evidence-Based Complementary and Alternative Medicine is the journal with the largest number of publications.The authors in the field have weak interinstitutional cooperation and exchange,and their research is mainly from China,with little international collaboration and exchange.At present,acupuncture treatment of myocardial I/R injury covers three aspects:specific acupoints,molecular biological mechanisms and clinical studies,which mainly focus on seven hot spots.Conclusion The bibliometric visual analysis visually demonstrated the current status,hot spots and frontier trends of acupuncture in the treatment of myocardial I/R injury.In the future,it is necessary to strengthen international collaboration,promote exchanges and cooperation between scholars and institutions,and promote the publication of multi-center,large-sample and high-level clinical randomized controlled studies;At the same time,the effect mechanism was further discussed from the perspectives of new molecular biological mechanisms,new intervention measures and point selection,and clinical translational research was carried out.

Objective To explore the mechanism of electroacupuncture improving myocardial ischemia-reperfusion injury(MIRI),electroacupuncture PC6 Attenuates TRPV1 pathway in spinal cord C5-T6 dorsal root ganglion(DRG)on MIRI rats was observed.Methods After one week of experimental feeding,30 SD rats with normal electrocardiogram were randomly divided into sham-operated group and model group,PC6 group,non-meridian and non-acupuncture group,and PC6+capsaicin(TRPV1 receptor agonist)group,with 6 rats in each group.The MIRI model was prepared by ligation of the left anterior descending(LAD)coronary artery in the other groups.The next day after modeling,electroacupuncture of the"PC6"point in the EA group,electroacupuncture of the caudal"non-meridian non-points"in the the non-meridian non-acupuncture point group,and electroacupuncture of the"PC6"point after intraperitoneal injection of capsaicin in the PC6+capsaicin group,20 min/d for 7 days.ECG was used to record the changes of ST level and LF/HF ratio in rats.Evans blue-TTC double staining and HE staining was used to observe the myocardial infarction area and the changes of myocardial tissue morphology.ELISA was used to detect the levels of serum CK-MB and cTnI.Immunofluorescence staining was used to the phenomenon of sympathetic-sensory coupling with TH-CGRP positive labeling in the DRG of rats.qPCR was to detect the mRNA expression of TRPV1,TH,CGRP,SP,ERK and AKT in rat DRG.Results Compared with the sham-operated group,rats in the model group showed significant higher ST level and LF/HF ratio(both P<0.001),and IA/AAR ratio increased significantly(P<0.0001).Massive inflammatory cell infiltration,serum CK-MB,cTnI levels up-regulated significantly(both P<0.0001).The formation of TH-CGRP-labeled sympathetic budding phenomenon in the DRG and the TRPV1,TH,CGRP in the DRG,SP,ERK,and AKT mRNA expression levels increased significantly(both P<0.01).Compared with the model group,the ECG of the endograft group was significantly improved(both P<0.001).The IA/AAR ratio decreased significantly in PC6 group(P<0.001).The myocardial infarction area reduced significantly(P<0.0001).The levels of serum CK-MB and cTnI down-regulated significantly(both P<0.0001),and the phenomenon of sympathetic sprouting within DRG was not evident,and the DRG of the 6 corresponding mRNA expression decreased significantly(both P<0.01).Compared with the PC6 group,the effect of treatment was not obvious in the non-meridian and non-acupuncture group and PC6+capsaicin group,and the electrocardiogram,IA/AAR ratio,myocardial infarcted area,and serum CK-MB,and cTnI levels did not improve(both P<0.01),and a large number of sympathetic budding phenomena were seen in the DRG.The expression of the mRNA corresponding to the phase of 6 increased significantly(both P<0.01).Conculsion Electroacupuncture PC6 may reduce myocardial injury by inhibiting TRPV1 pathway-mediated sympatheticsprouting in dorsal root ganglia.

Objective:To analyze the clinical features of pachydermoperiostosis (PDP) and improve its diagnostic level.Methods:A retrospective analysis was conducted on the clinical data of four patients with PDP treated at Sun Yat-sen Memorial Hospital, Sun Yat-sen University from 2015 to 2023, including clinical manifestations, laboratory tests, imaging examinations, and genetic testing results.Results:All four patients were male with an average onset age of 15 years old (ranging from 9 to 18 years old). One patient′s uncle had PDP, and another patient′s parents were consanguineous, though neither parent showed signs of PDP. All four patients exhibited clubbing, skin thickening, and acne; three had frontal bossing and deepened nasolabial folds; two showed scalp sulci changes on head MRI, and all had periosteal thickening of the phalanges visible on X-ray. One patient accompanied with hypokalemic nephropathy, and another had gastric ulcer. One patient underwent whole exome sequencing test which revealed a homozygous mutation, SLCO2A1 gene c.1406C>T, leading to a protein change p.Pro469Leu. Computational tools REVEL, SIFT, and Polyphen2 predicted this variant as deleterious.Conclusion:In addition to skin thickening, frontal bossing, scalp sulci changes, clubbing, and periosteal proliferation, patients with PDP may also present with hypokalemic nephropathy and gastric ulcer. The SLCO2A1 gene c.1406C>T mutation may be pathogenic.

Objective To explore the value of the Physiology and Surgical Severity Score(POSSUM)scoring system in predicting postoperative complications in elderly patients with thoracic surgery,and to ana-lyze its correlation with Clavien-Dindo classification.Methods The data of 182 elderly patients who under-went thoracic surgery in this hospital from October 2019 to March 2023 were retrospectively analyzed.They were divided into the complication group and the non-complication group according to whether there were complications after surgery.The baseline data and POSSUM score of the two groups were analyzed,and the receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of POSSUM for post-operative complications in elderly patients.POSSUM of patients with different Clavien-Dindo classification was compared,and the correlation between POSSUM and Clavien-Dindo classification analyzed.Results The incidence of pulmonary infection was the highest in the complication group,followed by hypoproteinemia.POSSUM in the complication group was higher than that in non-complication group before operation,and the difference was statistically significant(P＜0.05).The ROC curve showed that the area under curve(AUC)value of POSSUM was 0.829;In the complication group,according to Clavien-Dindo classification,there were 5 cases of grade Ⅰ,47 cases of grade Ⅱ,8 cases of grade Ⅱ Ⅲ,7 cases of grade Ⅳ and 8 cases of grade V,the difference was statistically significant(P＜0.05).The correlation analysis showed that POSSUM score was positively correlated with Clavien-Dindo classification(r＞0.513,P＜0.05).Conclusion The POSSUM scoring system has a high value in predicting postoperative complications in elderly patients with thoracic surgery.

Objective:To investigate the cause of death, survival time, and risk factors in patients diagnosed with Alzheimer′s disease (AD) at memory clinic.Methods:The patients with AD were enrolled from the memory clinic at Huashan Hospital, Fudan University between August 2002 and December 2006. Baseline data were collected and 7 rounds of telephone follow-up visits were conducted to track clinical outcomes. For death cases, the date and cause of death were recorded. Patients were divided into several subgroups based on gender and baseline cognition [Mini-Mental State Examination (MMSE) score]. Kaplan-Meier analysis and Cox proportional hazards regression models were constructed to analyze the survival time of patients and identify the risk factors.Results:A total of 499 patients were enrolled, including 199 males and 300 females. The follow-up time was 5.5(3.4,7.4) years, with longest follow-up time of 19.3 years. The median survival time after symptom onset was 11.8 years (95% CI 10.2-13.4 years), which was 12.4 years (95% CI 11.2-13.5 years) in females, significantly longer than that in males (10.2 years, 95% CI 9.6-10.8 years, logrank test, P=0.010). The median survival time after diagnosis was 8.3 years (95% CI 7.3-9.4 years), which was 8.8 years (95% CI 6.9-10.6 years) for women, significantly longer than that for men (6.8 years, 95% CI 5.7-7.9 years, logrank test, P=0.001). Patients with baseline MMSE scores≥15 ( n=265) had a median survial of 11.4 years (95% CI 9.5-13.2 years), significantly longer than those with poorer cognitive function (baseline MMSE scores<15; n=234, 7.4 years, 95% CI 6.4-8.4 years, logrank test, P<0.001). Multivariable Cox proportional hazards regression analysis showed that aging ( HR=1.027, 95% CI 1.002-1.052, P=0.034), lower body mass index (BMI; HR=1.081, 95% CI 1.023-1.139, P=0.007), lower baseline MMSE score ( HR=1.056, 95% CI 1.026-1.086, P<0.001), diabetes ( HR=1.716, 95% CI 1.076-2.735, P=0.023), and history of falls ( HR=1.536,95% CI 1.007-2.341, P=0.046) were independent risk factors for death (all P<0.05). During the follow-up, 224 of the participants died. Except for 62 cases of unknown reason, the top 6 causes of death were pneumonia (39 cases, 24.1%), cerebrovascular disease (24 cases, 14.8%), circulatory system disease(21 cases, 13.0%), multi-organ failure (17 cases, 10.5%), tumor (13 cases, 8.0%), eating disorders and malnutrition (13 cases, 8.0%). Conclusions:In the current study, the median survival time after onset for patients with AD was 11.8 years; aging, lower BMI, lower baseline cognition, comorbidities, and history of falls were independent risk factors for death; pneumonia was the most common cause of death.

Objective:To improve the awareness of cholesterol crystal embolism syndrome (CCE) inrheumatologists.Methods:The clinical characteristics of 40 Chinese CCE patients admitted to our department (one case) were summarize and in the literature (thirty-nine cases) were reviewed.Results:Among these 40 patients, 87.5%(35/40) were male and the mean age was (68±6) years. All patients suffered from athero-sclerosis and 87.5%(35/40) of them had precipitating factors such as endovascular intervention, vascular surgery, anticoagulant, or thrombolytic therapy. The clinical manifestations included renal insufficiency (90.0%, 36/40), blue toe syndrome (82.5%, 33/40), ulceration or gangrene (25.0%, 10/40), and livedo reticularis (15%, 6/40). Acute phase reactant was tested in 25 cases, of whom 84.0%(21/25) showed elevated C-reactive protein (CRP) and 56.0%(14/25) showed elevated erythrocyte sedimentation rate (ESR).Conclusion:Rheumatologists should be alert that CCE is one of the differential diagnosis of systemic vasculitis, especially for patients with severe atherosclerosis.

Objective:To improve the differential diagnosis of systemic sclerosis (SSc) with hypertension and renal insufficiency.Methods:The clinical characteristics, diagnosis and treatment of a SSc patient with hypertension and renal insufficiency were reported and discussed.Results:A middle-aged female patient with a history of SSc for 5 years, headache and gross hematuria for 10 days was admitted. Abrupt increase in blood pressure and creatinine, glomerular hematuria, proteinuria, low complement C3 and C4, positive antinuclear antibody (ANA), anti-dsDNA antibody and perinuclear antineutrophil cytoplasmic antibody (pANCA) were presented. Renal pathology showed lupus nephritis (LN) (type Ⅳ). After glucocorticoid pulse therapy, followed by cyclophosphamide, belimumab, and symptomatic treatment, the symptoms were relievedand lupus disease activity were decreased.Conclusion:For SSc patients with increased blood pressure and creatinine, the presence of other diseases should be considered in addition to scleroderma renal crisis. Renal biopsy and pathological examination should be performed to confirm the diagnosis and avoid misdiagnosis.
