The diagnostic value of tenascin-C in acute aortic syndrome

OBJECTIVES Misdiagnosis of acute aortic syndrome(AAS)significantly increases mortality.Tenascin-C(TN-C)is an extracellular matrix glycoprotein related to cardiovascular injury.The elevation of TN-C in AAS and whether it can discriminate suddenonset of acute chest pain in Chinese remains unclear.METHODS We measured the plasma concentration of TN-C by ELISA in a cohort of 376 patients with chest or back pain.Measures to discriminate AAS from acute coronary syndrome(ACS)were compared and calculated.RESULTS From October 2016 to September 2021,376 undiagnosed patients with chest or back pain were enrolled.166 of them were finally diagnosed as AAS,100 were ACS and 110 without cardiovascular diseases(NCV).TN-C was significantly elevated in AAS at 18.18 ng/mL(IQR:13.10–27.68)compared with 7.51 ng/mL(IQR:5.67–11.38)in ACS(P<0.001)and 3.68 ng/mL(IQR:2.50–5.29)in NCV(P<0.001).There was no significant difference in TN-C level among the subtypes of AAS.Of the 166 AAS patients,the peaked level of TN-C was at acute stage(P=0.012),then a slight of decrease was observed at subacute stage.The area under receiver operating characteristic curve for AAS patients versus NCV was 0.979(95%CI:0.964-0.994)for TN-C.At a cutoff level of 11.474 ng/mL,TN-C has a sensitivity of 76.0%,specificity of 85.5%,accuracy of 82.0%,positive predictive value(PPV)of 76.0%,negative predictive value(NPV)of 85.5%.Diagnostic performance of TN-C was superior to D-dimer and hs-cTnT.CONCLUSIONS The concentration of serum TN-C in AAS patients was significantly higher than that in ACS patients and NCV.TN-C could be a new biomarker to distinguish AAS patients in the early stage after symptoms onset from other pain diseases.

Primary prostate Burkitt's lymphoma resected with holmium laser enucleation of the prostate:A rare case report

BACKGROUND Primary prostate Burkitt's lymphoma is a rare and aggressive condition with a poor prognosis.Its clinical presentation can be challenging to differentiate from benign prostatic hyperplasia.Given the rarity of primary prostate Burkitt's lymphoma,its diagnosis and treatment remain unclear.CASE SUMMARY This report presents a case of a 57-year-old male with primary prostate Burkitt's lymphoma,initially misdiagnosed as prostatic hyperplasia.This case's operative process,intraoperative findings and postoperative management are discussed in detail.CONCLUSION Primary prostate lymphoma is difficult to distinguish from other prostate diseases.Holmium laser enucleation of the prostate(HoLEP),a minimally invasive procedure,is crucial in diagnosing and treating this rare disease.Clinicians should remain vigilant and thoroughly combine physical examination,imaging and test results when encountering patients of younger age with small prostate size but a rapid progression of lower urinary tract symptoms.HoLEP is an essential diagnostic and therapeutic tool in managing primary prostate Burkitt's lymphoma.

Bone marrow edema in a postpartum female following ankle sprain: a case report

Bone marrow edema(BME)is characterized by an accumulation of interstitial fluid within the bone marrow,the cancellous,hematopoietic compartment within bones.[1]BME is divided into two principal categories:idiopathic or primary BME,with an unknown etiology,and secondary BME,which occurs as a result of an identifiable underlying pathology.[2]Although the prevalence of BME is not limited to specific demographic parameters,it shows a predilection for males or individuals assigned male at birth,predominantly aged between the ages of 30 and 60 years,especially in cases of bone marrow edema syndrome(BMES),a rare idiopathic variant.[3]The etiological spectrum of BME is diverse,including oncological entities(such as acute myeloid leukemia and osteosarcoma),degenerative diseases(such as osteoarthritis),infectious processes(osteomyelitis),ischemic conditions(avascular necrosis),metabolic dysfunctions(osteoporosis),inflammatory disorders(rheumatoid arthritis),and traumatic injuries(such as stress fractures).[1,2]Clinically,BME primarily manifests as localized pain,often accompanied by joint effusion and warmth near the affected joint.Diagnostic protocols typically include physical examination,serological assays,bone marrow biopsies,dual-energy X-ray absorptiometry(DEXA)scans,magnetic resonance imaging(MRI),and ultrasonography,with computed tomography(CT)scans and radiographs being less effective.

Relationship of Inflammation and Endothelial Dysfunction with Risks to Cardiovascular Disease among People in Inner Mongolia of China

Objective To explore the relationship of inflammation and endothelial dysfunction with risks to cardiovascular disease （CVD）. Methods Blood pressure, body weight, body height, waist circumference and lifestyle risk factors were measured and studied among 2589 participants in Inner Mongolia of China, and biomarkers of inflammation and endothelial dysfunction including high-sensitivity C-reactive protein （hsCRP）, soluble inter-cellular adhesion molecule-1 （slCAM-1）, soluble E-selectin （sE-selectin）, and angiotensin II were investigated. Results Subjects with metabolic risk factors for CVD had higher levels of hsCRP, sE-selectin and slCAM-1 than those without such risk factors （all P〈O.05）. Levels of all biomarkers positively and significantly increased with aggregation of the metabolic risk factors among the subjects （all P for trend 〈0.001）. Data from the multivariate analysis showed that participants with high levels of hsCRP [odds ratio （OR}： 1.96, 95% confidence interval （CI）： 1.52-2.53], sE-selectin （OR： 1.35, 95% Cl： 1.05-1.72）, and angiotensin II （OR： 1.81, 95% CI＂ 1.40-2.33） were more likely to develop hypertension; participants with high levels of hsCRP （OR： 2.33, 95% CI： 1.85-2.94）, sE-selectin （OR： 1.24, 95% CI： 1.00-1.54）, and slCAM-1 （OR： 1.70, 95% CI： 1.30-2.22） were more likely to develop dyslipidemia, and those with high levels of hsCRP （OR： 2.95, 95% CI： 2.27-3.83） and slCAM-I（OR： 2.80, 95% CI： 2.06-3.80） were more likely to develop hyperglycemia. Conclusion Biomarkers of inflammation and endothelial dysfunction were separately associated with relevant metabolic risk factors for CVD. And appropriate measures should be taken to control inflammation and improve endothelial function among individuals with different metabolic risk factors for CVD.

The Role of NM23 in Patients with Colorectal Cancer:A Systematic Review and Meta-Analysis

This meta-analysis was carried out to evaluate the relationship between NM23 expression and the prognosis of patients with colorectal cancer. We searched Pub Med, EMBASE and Web of Science for relevant articles. The pooled odd ratios（ORs） and corresponding 95%CI were calculated to evaluate the prognostic value of NM23 expression in patients with colorectal cancer, and the association between NM23 expression and clinicopathological factors. In total, 2289 patients were pooled from 24 available studies. The incorporative OR combined by 16 studies with overall survival showed that high NM23 expression was associated with better overall survival（OR=0.67, 95%CI： 0.49–0.93, P=0.02, I2=56%, Ph=0.004）. And a new estimate without heterogeneity was produced when only combining high-quality studies（OR=0.70, 95%CI： 0.56–0.86, P=0.0007, I2=46%）. In disease free survival（DFS）, we also obtained a good prognosis（OR=0.30, 95%CI： 0.14–0.68, P=0.004）. Although we failed to find any significance in N status（P=0.10）, elevated NM23 expression was related to well tumor differentiation（OR=0.60, 95%CI： 0.44–0.820, P=0.001） and Dukes＇ A＆B（OR=0.55, 95%CI： 0.32–0.95, P=0.03）. These results indicated that over-expressed NM23 might be an indicator of good prognosis, well tumor differentiation and Dukes＇ A＆B of patients with colorectal cancer, but no significance was found in N status.

Comparison of Clinical Value between Right Distal Radial Artery Access and Right Radial Artery Access in Patients Undergoing Coronary Angiography or Percutaneous Coronary Intervention

Objective:To compare the feasibility and safety between right distal radial artery access and right radial artery access in patients undergoing coronary angiography(CAG)or percutaneous coronary intervention(PCI).Methods:On the basis of arterial access,113 patients who underwent CAG or PCI in Kunshan Hospital of Traditional Chinese Medicine between January and October 2018 were divided into two groups:a right distal radial artery group(52 patients)and a right radial artery group(61 patients).We collected general information,the number of puncture attempts,access times,postoperative compression time,and complications.Results:The general characteristics,rate of successful radial artery puncture,and rate of successful catheter placement in the two groups were not different.The right radial artery group had fewer puncture attempts(1.26±0.44 times vs.2.19±0.53 times,P=0.001)and a shorter access time(3.23±0.86 min vs.4.77±1.49 min,P=0.001)than the right distal radial artery group.However,the postoperative compression time in the right distal radial artery group was shorter(3.44±0.9 h vs.7.16±1.21 h,P=0.001).Two cases of bleeding,four cases of hematoma,and one case of artery occlusion in the right radial artery group and one case of hematoma in the right distal artery group occurred before discharge.The rate of total complications in the right distal radial artery group was lower than in the right radial artery group(1.93%vs.11.48%,P=0.048).Conclusion:CAG or PCI through the right distal radial artery is feasible and safe.

Effect of thalidomide combined with CHOP on immune function, angiogenesis and inflammatory factors in patients with diffuse large B-cell lymphoma

Objective:To mainly explore the effect of thalidomide combined with CHOP chemotherapy regimen on immunoglobulin,VEGF,lactate dehydrogenase,inflammatory factors and other related factors in patients with diffuse large B-cell lymphoma.Methods:A total of 83 patients with diffuse large B-cell lymphoma admitted to the Department of Hematology and Oncology in our hospital from December 2012 to December 2018 were collected.CHOP chemotherapy was given to 40 patients in the chemotherapy group.And 43 patients in the thalidomide group were treated with thalidomide combined with CHOP chemotherapy.Immunoglobulin IgG,IgA,IgM,vascular endothelial growth factor(VEGF),tumor necrosis factor(TNF-α),lactate dehydrogenase(LDH),β2 microglobulin(β2-MG),Th17 cell ratio and natural killer cell(NK)ratio were measured before and after treatment.Results:There were no significant differences in immunoglobulin,inflammatory cytokines and other related factors between the two groups before treatment(P>0.05).After 6 cycles of treatment,the levels of immunoglobulin IgG,IgA,IgM,VEGF,LDH,β2-MG and the ratio of NK cells in the chemotherapy group were significantly lower than those before treatment(P<0.05);TNF-αand the ratio of Th17 cells were significantly higher than that those before treatment.The levels of IgG,IgA,IgM,VEGF,LDH andβ2-MG in the thalidomide group were significantly lower than those before treatment(P<0.05).The levels of TNF-α,Th17 cells and NK cell rates were significantly higher than those before treatment(P<0.05).In addition,the levels of IgG,IgA,IgM,VEGF,LDH andβ2-MG in the thalidomide group were significantly lower than those in the chemotherapy group(P<0.05),and the level of TNF-α,the rates of Th17 cells and NK cells were significantly higher than those in the chemotherapy group(P<0.05).Conclusion:Thalidomide combined with CHOP chemotherapy has a significant therapeutic effect on diffuse large B-cell lymphoma.Thalidomide combined with CHOP chemotherapy can significantly reduce the levels of angiogenesis VEGF,lactate dehydrogenase andβ2-MG in patients,significantly regulate the immune function of patients,and improve the Th17 cell rate and natural killer cell rate and the level of TNF-αin the body.This article provides the basis for the treatment of clinical diffuse large B cell lymphoma.

Erxian decoction potentially prevents postmenopausal osteoporosis by modulating miR-335: a study based on bioinformatics analysis and preliminary clinical case validation

Background:miRNAs are closely related to bone metabolism.Studies have shown that Erxian decoction can improve bone metabolism,possibly achieving this regulatory effect through miRNA targets.Netinfer was used to predict the miRNA targets of Erxian decoction for the treatment of postmenopausal osteoporosis,and the results were validated by clinical trials.Methods:In this study,we identified possible targets of Erxian decoction in osteoporosis by means of network pharmacological analysis and bioinformatic prediction.Fifteen cases of postmenopausal osteoporosis with kidney Yin and Yang deficiency(In traditional Chinese medicine,kidney Yin nourishes and moistens the tissues of the internal organs of the body,while kidney Yang promotes and warms the tissues of the internal organs of the body.)were treated with Erxian decoction for four weeks,and serum bone metabolism indices(P1NP,osteocalcin,andβ-CTX)and miRNA-335-5p expression were measured before and after treatment.Results:The constructed miRNA postmenopausal osteoporosis related gene network of the effective compound of the Erxian decoction has 296 points and 981 edges.The 39 postmenopausal osteoporosis related genes regulated by miRNA-335-5p were enriched in ossification,while the signaling pathways were enriched in rheumatoid arthritis,the Toll signaling pathway,the HIF-1 signaling pathway,and the MAPK signaling pathway.After taking Erxian decoction,the expression of the serum bone formation index(P1NP,osteocalcin)and miRNA-335-5p gene expression levels increased significantly.The alterations in P1NP and osteocalcin were correlated with the changes in miRNA-335-5p.Conclusion:Circulating miRNA-335-5p may serve as an important target of Erxian decoction in the treatment of postmenopausal women.The effect of Erxian decoction on bone formation is significant,but the underlying mechanism requires further investigation.

Antioxidant and anti-inflammatory injectable hydrogel microspheres for in situ treatment of tendinopathy

Tendinopathy is a common disorder that causes local dysfunction and reduces quality of life.Recent research has indicated that alterations in the inflammatory microenvironment play a vital role in the pathogenesis of tendinopathy.Herein,injectable methacrylate gelatin(GelMA)microspheres(GM)were fabricated and loaded with heparin-dopamine conjugate(HDC)and hepatocyte growth factor(HGF).GM@HDC@HGF were designed to balance the inflammatory microenvironment by inhibiting oxidative stress and inflammation,thereby regulating extracellular matrix(ECM)metabolism and halting tendon degeneration.Combining growth factors with heparin was expected to improve the encaption,the catechol groups on dopamine have adhesion and antioxidant properties,allowing potential attachment at the injured site,and better function synergized with HGF.GM@HDC@HGF injected in situ in rat Achilles tendinopathy(AT)models significantly downregulated oxidative stress and inflammation,and ameliorated ECM degradation.In conclusion,the multifunctional platform developed presents a promising alternative for the treatment of tendinopathy.

Acupuncture and moxibustion for malignant tumor patients with psychological symptoms of insomnia,anxiety and depression:a systematic review and Meta-analysis

OBJECTIVE:To evaluate the efficacy and safety of acupuncture and moxibustion therapy(AMT) for cancerrelated psychological symptoms(CRPS) of insomnia,depression and anxiety.METHODS:Seven databases were searched for randomized controlled trials(RCT) comparing AMT to routine care or conventional drug for alleviating CRPS of insomnia,depression,and anxiety before April 2020.Two independent reviewers performed the data extraction and assessed the risk of bias.RESULTS:A total of 30 RCTs involving 2483 cancer patients were enrolled.The pooled analysis indicated that the treatment group was significantly better than the control group in improving the depression effective rate [RR = 1.29,95% CI(1.12,1.49),P = 0.0004],the quality of life(QOL) [MD = 1.11,95% CI(0.80,1.42),P < 0.000 01],and reducing Self-rating Anxiety Scale(SAS) [MD =﹣7.75,95% CI(﹣10.44,﹣5.05),P < 0.000 01].But there was no statistically significant difference between two groups in improving the insomnia effective rate [RR = 1.18,95% CI(0.93,1.51),P = 0.18].The subgroup analysis showed the effectiveness of different intervention on CRPS.Compared with routine care,AMT helps relieve CRPS better evaluated by Pittsburgh Sleep Quality Index(PSQI),Hamilton Depression Scale(HAMD),and Self-rating Depression Scale(SDS),and depression effective rate.Compared with conventional drug,AMT performs better evaluated by SDS,depression effective rate and QOL.Moreover,the conventional drug showed higher treatment efficacy on improving insomnia effective rate compared with AMT.Compared to conventional drug,AMT plus conventional drug resulted in a significant reduction on CRPS such as PSQI,HAMD,SDS,and SAS,and also had a meaningful improvement on insomnia effective rate,depression effective rate and QOL.Fewer published reports were found on the adverse events of AMT than the conventional drug.CONCLUSION:The results suggested that AMT might be effective in improving CPRI;however,a definite conclusion could not be drawn because the quality of trials are low.Further large-scale and high-quality RCTs to verify the efficacy and safety of AMT on CRPS are still warranted.

Influence of administrative intervention on the availability,utilization, and competency for the use of defibrillators in primary hospitals

To the Editor:Sudden cardiac death is a major public health issue across the world.[1] Timely cardiopulmonary resuscitation (CPR) and defibrillation helps improve prognosis and avert the neurological sequelae of ventricular fibrillation.[2] However,there is low availability and utilization of defibrillators in China.[3] Hence,we investigated the availability and utilization of defibrillators during two consecutive years (before and after an administrative intervention) at all primary (public and private) hospitals in Suzhou city (Jiangsu province,China) to assess the effect of administrative intervention.

Early warning prevention and control strategies to reduce perioperative venous thromboembolism in patients with gastrointestinal cancer

BACKGROUND Venous thromboembolism(VTE)is a major cause of unexpected and perioperative in-hospital deaths.It is characterized by high morbidity,high mortality,high misdiagnosis rate,and high missed diagnosis rates.VTE is a common postoperative complication in cancer patients.VTE is preventable,and early identification of risk factors leading to VTE and appropriate early preventive actions can reduce its occurrence and mortality.Presently,there is no uniform standard for the prevention and control of VTE in clinical practice,and hospitals in China lack mature and effective protocols for the assessment,prevention,and treatment of VTE.AIM To explore whether an early warning program could influence the occurrence of deep vein thrombosis(DVT)postoperatively.METHODS This is a comparative retrospective cohort study,which enrolled patients who underwent laparotomic or laparoscopic gastrointestinal tumor resection for gastrointestinal cancer between January 2016 and December 2019.Patients were divided into a control group and an early warning group depending on whether or not the early warning program was implemented.A venous thromboembolism prevention and control team was established.The outcomes included the occurrence of DVT,the correct rate of VTE assessment,the coagulation indicators,and the mastery of VTE knowledge by the nurses.RESULTS A total of 264 patients were included in this study,with 128 patients in the control group and 136 patients in the early warning group.The occurrence rate of DVT in the early warning group was 6.6%(9/136),compared with 14.1%(18/128)in the control group(P<0.05).The correct rates of VTE risk assessment by the nurses and standard implementation rate of VTE preventive measures were 86.8%vs 65.6%and 80.2%vs 57.8%in early warning and control groups,respectively(all P<0.001).The independent factors associated with postoperative DVT occurrence were age(OR=1.083,95%CI:1.070-3.265,P=0.032),Hyperlipidemia(OR=1.127,95%CI:1.139-2.564,P=0.042),preoperative high VTE risk(OR=2.131,95%CI:1.085-5.178,P=0.001),time of operation(OR=2.268,95%CI:2.005-5.546,P=0.026)and not adoption of early warning prevention(OR=3.747,95%CI:1.523-6.956,P=0.017).CONCLUSION The early warning strategy was independently associated with the decreasing occurrence of VTE,and it might be suitable for protection from VTE in patients undergoing gastrointestinal cancer surgery.

Tuina Intervention and Sleep and Emotional Disorders due to Chronic Fatigue Syndrome HAN Chou-ping

Objective： To study the tuina effect on sleep disorder and emotional problems of chronic fatigue syndrome （CFS） cases. Method： Thirty CFS cases were treated in the treatment group, by applying one-thumb pushing, rolling and pressing-kneading manipulations along the Governor Vessel, Bladder and Yangming Meridians. The intended major points include Fengfu （GV 16）, Yaoyangguan （GV 3）, Xinshu （BL 15）, Pishu （BL 20）, Ganshu （BL 18）, Hegu （LI 4） and Taixi （KI 3）. The treatment was done once every other day; 10 times constitute a course of treatment. Another 30 healthy cases were selected in the control group, without any intervention. The sleep quality and mental state in the two groups were evaluated by PSQI, HAMA and HAMD. In addition, the pre-treatment and post-treatment score changes were observed. Results： Before treatment, the total score of PSQI, sleep quality, time of falling asleep, sleep efficiency, sleep disorder, daytime functional impairment, and scores of HAMD and HAMA in treatment group were all substantially higher than the control group （P〈0.01）. After 10 tuina treatments, the total score of PSQI, time of falling asleep, sleep disorder and daytime flmctional impairment as well as scores of HAMD and HAMA in treatment group were significantly changed, compared with before treatment, P〈0.05. Conclusion： Those with CFS may present with sleep disorder and mental or psychological abnormality, tuina can improve their sleep quality and adjust their mental conditions.
