Objective To explore the correlations of evaluations of right heart function parameters in patients with Ebstein anomaly(EA)using echocardiography and cardiac MRI.Methods Data of transthoracic echocardiography and cardiac MRI in 32 patients with EA confirmed by operation were retrospectively analyzed.The correlations of cardiac cavity size,right ventricular function and strain parameters obtained using echocardiography and the functional right ventricular(fRV)ejection fraction(EF)measured using MRI were explored.Results MRI fRV-EF in 32 cases of EA was(23.20± 7.61)％.Among echocardiographic parameters in 32 cases of EA,fractional area change(FAC)of fRV(r=0.347,P=0.015)was slightly,while global longitudinal strain(GLS)of fRV(r=0.801,P＜0.001)was highly positively correlated with MRI fRV-EF,respectively,whereas atrialized right ventricle(aRV)area/fRV area(r=-0.730,P=0.007)was highly negatively,aRV area/left ventricular area(r=-0.450,P=0.042)and right ventricular anterior-posterior diameter(r=-0.650,P=0.022)were both moderately negatively correlated with MRI fRV-EF.Both the left ventricular eccentricity index(r=-0.347,P=0.049)and Glasgow outcome scale extended(r=-0.336,P=0.024)obtained with echocardiography were slightly negatively correlated MRI fRV-EF.Conclusion Right heart function parameters in EA patients obtained with echocardiography were correlated with those of MRI fRV-GLS,among which aRV area/fRV area were highly positively correlated with MRI fRV-EF,hence having great value for evaluating right heart function in EA patients.

Objective:To evaluate the efficacy and safety of hypomethylating agents (HMA) in patients with myelodysplastic syndromes (MDS) .Methods:A total of 409 MDS patients from 45 hospitals in Zhejiang province who received at least four consecutive cycles of HMA monotherapy as initial therapy were enrolled to evaluate the efficacy and safety of HMA. Mann-Whitney U or Chi-square tests were used to compare the differences in the clinical data. Logistic regression and Cox regression were used to analyze the factors affecting efficacy and survival. Kaplan-Meier was used for survival analysis. Results:Patients received HMA treatment for a median of 6 cycles (range, 4-25 cycles) . The complete remission (CR) rate was 33.98% and the overall response rate (ORR) was 77.02%. Multivariate analysis revealed that complex karyotype ( P=0.02, OR=0.39, 95% CI 0.18-0.84) was an independent favorable factor for CR rate. TP53 mutation ( P=0.02, OR=0.22, 95% CI 0.06-0.77) was a predictive factor for a higher ORR. The median OS for the HMA-treated patients was 25.67 (95% CI 21.14-30.19) months. HMA response ( P=0.036, HR=0.47, 95% CI 0.23-0.95) was an independent favorable prognostic factor, whereas complex karyotype ( P=0.024, HR=2.14, 95% CI 1.10-4.15) , leukemia transformation ( P<0.001, HR=2.839, 95% CI 1.64-4.92) , and TP53 mutation ( P=0.012, HR=2.19, 95% CI 1.19-4.07) were independent adverse prognostic factors. There was no significant difference in efficacy and survival between the reduced and standard doses of HMA. The CR rate and ORR of MDS patients treated with decitabine and azacitidine were not significantly different. The median OS of patients treated with decitabine was longer compared with that of patients treated with azacitidine (29.53 months vs 20.17 months, P=0.007) . The incidence of bone marrow suppression and pneumonia in the decitabine group was higher compared with that in the azacitidine group. Conclusion:Continuous and regular use of appropriate doses of hypomethylating agents may benefit MDS patients to the greatest extent if it is tolerated.

Objective To study the feasibility and safety of right ventricular angiography(RVG)to as-sist pacing in the left bundle branch region(LBBaP).Methods The retrospective study was adopted.A total of 67 patients receiving LBBaP in this hospital from January 2019 to June 2022 were included as the study sub-jects.The basic information of the patients was collected,including the sex,age,clinical diagnosis,EKG pa-rameters,etc.The RVG three-stage adjuvant LBBaP was adopted.The specific operation was to perform RVG under the right anterior oblique perspective of 30°.A straight line was connected between the highest point of the tricuspid valvular ring and the apex of the right ventricle,and then the straight line was divided into 3 e-qual parts.The proximal junction was the LBBaP electrode implantation area.The success of LBBaP operation was defined as the simultaneous satisfaction of right bundle branch block form of QRS wave in unipolar pa-cing,QRS wave width(QRSd)＜130 ms and peak time of left ventricular excitation＜90 ms.The operation related parameters and occurrence situation of complications were recorded.The follow up was conducted in 1,3,6,12 months.The electrode parameters,electrocardiogram and color Doppler ultrasound results were recor-ded.Results Among 67 patients,43 cases were males aged(65.0±8.0)years old;twenty-two cases(32.8％)were symptomatic sick sinus syndrome,and 45 cases(67.2％)were second-degree type Ⅱ and above atrioven-tricular block.The preoperative QRS width(QRSd)was(103.0±22.0)ms.The LBBaP operation success was in 61 cases(91.0％).The operation time was(134.6±32.3)min,and the X-ray exposure time was(43.6±12.6)min.The pace-making threshold value was(0.8±0.4)V,the R wave perception amplitude was(12.1±4.7)mV,and the impedance was(741.2±130.8)Ω.At 1 V pacing,the peak time of left ventricular activation in the lead V5 was(83.4±13.7)ms.The postoperative QRSd was(116.5±18.3)ms.During the operation,8 cases developed interventricular septal perforation and 1 case developed bundle branch injury.No other serious complications occurred.After 12 months of follow-up,all patients had stable electrode parame-ters.Conclusion RVG three-stage adjuvant LBBaP is a simple,feasible and safe physiological pacing method.

Objective To explore the applicability,safety and effectiveness of hepatic arterial infusion chemotherapy(HAIC)combined with sintilimab and bevacizumab in the patients with intermediate and ad-vanced hepatocellular carcinoma(HCC)failed by lenvatinib treatment.Methods A total of 62 patients with intermediate and advanced liver cancer failed by lenvatinib treatment in this hospital from February 2023 to February 2024 were selected as the study subjects and divided into the HAIC group(n=13),HAIC+targeted therapy group(n=18)and HAIC+combined therapy group(n=31)according to different treatment regi-mens.The HAIC group only received the HAIC treatment,the HAIC+targeted therapy group adopted the HAIC+lenvatinib combined treatment and the HAIC+combined treatment group received the HAIC+sintil-imab and bevacizumab combined treatment.The objective remission rate(ORR),disease control rate(DCR),median progression-free survival time(mPFS),median overall survival time(mOS),carcinoembryonic antigen(CEA),vascular endothelial growth factor(VEGF),carbohydrate antigen 125(CA125)levels after treatment were observed in 3 groups,and the treatment related adverse reactions were recorded.The Kaplan-Meier method was used for conducting the survival analysis.Results According to RECIST1.1 criteria,ORR of the HAIC+combined treatment group was higher than that of the HAIC group and HAIC+targeted therapy group(35.5％vs.23.1％vs.22.2％),DCR was lower than that of the other two groups(83.8％vs.92.3％vs.88.9％),but the differences were not statistically significant and the differences were not statistically sig-nificant(P＞0.05).mOS of the HAIC+combined treatment group was longer than that of the HAIC group and HAIC+targeted therapy group[18.1(95％CI:13.3-22.9)months vs.12.6(95％CI:9.0-16.2)months vs.15.9(95％CI:11.5-20.3)months].mPFS in the HAIC+combined treatment group was longer than that in the the HAIC group and HAIC+targeted therapy group[12.0(95％CI:9.4-14.6)months vs.9.7(95％CI:2.2-17.2)months vs.10.1(95％CI:8.3-11.9)months],and the differences were not statistically sig-nificant(P＞0.05).The levels of CEA,VEGF and CA125 after treatment in 3 groups were decreased com-pared with before treatment,moreover the levels in the HAIC+combined treatment group was the lowest(P＜0.05).There was no statistically significant difference in the incidence rate of adverse reactions among the three groups(P＞0.05).Conclusion The HAIC combined with immunotherapy regimen is effective in the pa-tients with intermediate and advanced HCC failed by lenvatinib treatment,moreover which has high safety.

Objective To investigate the clinical characteristics of asthma patients with deficiency of various viscera through the analysis of mitochondrial dysfunction and related influencing factors,and to explore the DDAH1/L-Arg/ADMA pathway as well as the trend of changes in the mitochondrial function and oxygen metabolism of the asthma patients through the analysis.Methods A total of 122 patients with acute exacerbation of bronchial asthma who met the inclusion criteria were selected,and their clinical data were collected.The patients were divided into 3 groups based on the criteria of visceral deficiency syndrome differentiation,namely lung qi deficiency group(47 cases),lung-spleen qi deficiency group(39 cases),and lung-spleen-kidney deficiency group(36 cases).Meanwhile,the normal control group including 44 cases was set up.For the asthma patients with visceral deficiency,an observation was conducted in the lung function indicators of forced expiratory volume in the first second(FEV1),the ratio of FEV1 to forced vital capacity(FEV1/FVC)and peak expiratory flow(PEF)as well as the severity of the disease.Moreover,venous blood was sampled from the patients for the detection of L-arginine(L-Arg)and asymmetric dimethylarginine(ADMA)levels with high-performance liquid chromatography coupled with mass spectrometry(HPLC-MS/MS),and for the detection of arginine metabolism related indicators of protein arginine methyltransferase 1(PRMT1)and dimethylarginine dimethylammonium hydrolysate 1(DDAH1)as well as the oxidative damage parameters of reactive oxygen species(ROS),thiobarbituric acid reactive substance(TBARS),8-iso-prostaglandins(8-iso),lipid peroxide(LPO),and malondialdehyde(MDA)with enzyme-linked immunosorbent assay(ELISA).The platelet mitochondria were extracted from asthma patients and normal controls,and then the mitochondrial membrane potential(MMP),adenosine triphosphate(ATP),and activities of cytochrome C oxidase(COX)in the platelet were determined by JC-1 flow cytometric assay in order to assess the mitochondrial function.The changes in the mitochondrial function and their influence on the mitochondrial function of asthma patients with deficiency of various viscera were analyzed and then compared with those of the normal control group.Results(1)There were statistically significant differences in the age and lung function(FEV1,FEV1/FVC,PEF)among asthma patients with deficiency of various viscera(P＜0.01):the age of the lung-spleen-kidney deficiency group was significantly older than that of the lung qi deficiency group and the lung-spleen qi deficiency group(P＜0.05),and the lung function(FEV1,FEV1/FVC,PEF)showed a significant downward trend with the aggravation of viscera deficiency(P＜0.05).(2)There was a statistically significant difference in the illness grading of patients with deficiency of various viscera(P＜0.01).In the lung qi deficiency group,the illness status was predominated by intermittent state of asthma(grade 1),accounting for 65.96%,and then followed by mild asthma(grade 2),accounting for 25.53%.In the lung-spleen qi deficiency group,the illness status was predominated by moderate asthma(grade 3),accounting for 41.03%,and then followed by intermittent state of asthma(grade 1),accounting for 30.77%.In the lung-spleen-kidney deficiency group,the illness status was predominated by severe asthma(grade 4),accounting for 52.78%,and then followed by moderate asthma(grade 3),accounting for 33.33%.It is indicated that with the aggravation of viscera deficiency,the severity of asthma tended to be aggravated.(3)There were significant differences in plasma 8-iso,ROS,LPO and MDA levels between asthma patients with deficiency of various viscera and normal control group(P＜0.05).The plasma 8-iso and LPO levels of the asthma patients with deficiency of various viscera and the plasma MDA and ROS levels of asthma patients with lung-spleen qi deficiency and lung-spleen-kidney deficiency were significantly higher than those in normal control group(P＜0.05),and the plasma ROS level of asthma patients with lung-spleen qi deficiency and lung-spleen-kidney deficiency was significantly higher than that in asthma patients with lung qi deficiency(P＜0.05).The plasma TBARS level of asthma patients with deficiency of various viscera tended to be higher than that of normal control group,but the difference was not statistically significant(P＞0.05).It is indicated that reactive oxygen species and peroxide lipids accumulated in the body of asthma patients with deficiency of various viscera,and their levels increased with the aggravation of visceral deficiency.(4)The levels of MMP,ATP and COX in asthma patients with deficiency of various viscera were significantly lower than those in normal control group(P＜0.05),and the activity of COX decreased with the aggravation of visceral deficiency.(5)The levels of plasma L-Arg,L-Arg/ADMA and DDAH1 in asthma patients with deficiency of various viscera were significantly lower than those in normal control group(P＜0.05),and their levels decreased gradually with the aggravation of visceral deficiency.There was no significant difference in the plasma ADMA and PRMT1 levels between asthma patients with deficiency of various viscera and normal control group(P＞0.05).Conclusion It is indicated that the visceral deficiency in asthma patients is consistent with the progression of illness status,oxygen metabolism and its influencing factors,and the degree of oxidative damage.It is suggested that the progression of illness status can be judged by visceral deficiency in traditional Chinese medicine according to the parameters of body metabolism.

Objective To report the clinical and imaging characteristics of a case with the clinical manifestation of multiple lung and liver nodules,diagnosed as IgG4-related hepatic inflammatory pseudotumor(HIPT)complicated by hepatic tissue-infection,and review the literature in order to facilitate clinical diagnosis and differential identification of IgG4-related HIPT.Methods A retrospective analysis was conducted on the medical records of a patient with IgG4-related disease(IgG4-RD)characterized by multiple lung and liver nodules.A literature review was performed by searching Chinese and English databases to summarize the clinical and imaging characteristics of IgG4-related HIPT and hepatic tissue infection.Results The case involved a 64-year-old female admitted to the Rheumatology and Immunology Department of the First Medical Center of Chinese PLA General Hospital due to"poor appetite and fatigue for over a year,and dry cough for four months".She presented with multiple nodules in the lungs and liver,without involvement of the eyelids,salivary glands,submandibular glands,or pancreas.Laboratory test results revealed elevated serum IgG4 levels at 14.1 g/L and C-reactive protein(CRP)at 82.1 mg/L.Pulmonary CT scans indicated multiple solid nodules in both lungs with clear boundaries.Abdominal contrast-enhanced MRI revealed a nodule in liver segment S7 with a pseudocapsule around it,clear boundaries,and uniform enhancement;another nodule in liver segment S5 with blurred boundaries and ring enhancement.The final diagnosis of the liver nodules was confirmed by pathological and metagenomic sequencing to be an IgG4-related HIPT in segment S7 and hepatic tissue infection in segment S5.After a full course of anti-infection and treatment with methylprednisolone and leflunomide,follow-up imaging showed near-complete resolution of the lung and liver nodules.Literatures were searched in China National Knowledge Infrastructure(CNKI),Wanfang,and PubMed databases(up to September 2023),and no case of IgG4-RD complicated with both liver involvement and infection was found.A total of 26 cases of IgG4-RD involving the liver have been reported so far,predominantly in males(92.3%),with an average age of 51 years.Most patients presented with abnormal liver function as the initial symptom,with normal blood inflammatory markers.Imaging typically shows a single nodule in 88.5%of cases,with clear boundaries and uniform enhancement,as well as ring enhancement.Concurrent involvement of the pancreas and biliary tract is common.Pathology is the gold standard for confirming the disease.Conclusions This case reports coexistence of IgG4-related HIPT and infection within multiple hepatic nodules.In the diagnosis and treatment of patients with IgG4-RD presenting with multiple hepatic nodules,if the imaging characteristics of the nodules are inconsistent,it is necessary to consider the possibility of the underlying disease coexisting with other conditions,which can be easily misdiagnosed.Actively obtaining pathological tissue is crucial for aiding in the definitive diagnosis.

Aim To explore the mechanism of Yanghe decoction-containing serum on the migration and inva-sion of MCF-7 breast cancer cells in a co-culture sys-tem with M2 tumor-associated macrophages(TAMs)based on the paracrine epidermal growth factor(EGF)/epidermal growth factor receptor(EGFR)sig-naling pathway.Methods The M2-type TAMs model was induced from THP-1 monocytic cell line through in vitro treatment with phorbol 12-myristate 13-acetate(PMA)and recombinant human macrophage colony-stimulating factor(M-CSF).The MCF-7 cells were co-cultured with M2-type TAMs using a Transwell non-contact co-culture system to evaluate their effects on migration and invasion.Subsequently,the cells were intervened with serum containing Yanghe decoction,and the proliferation of MCF-7 cells was detected using the CCK-8 assay,while their lateral migration ability was assessed through scratch assays.The invasion and vertical migration abilities of the cells were evaluated separately using Transwell assays,and the concentra-tion of EGF was measured using ELISA.Finally,the expression of EGFR,MCP-1,and MMP9 proteins was detected using Western blot.Results Compared to the control group,Yanghe decoction-containing serum in-hibited the proliferation of MCF-7 cells before and after co-culture.The serum reduced the scratch healing a-bility before and after co-culture and decreased their migration and invasion abilities.Additionally,Yanghe decoction-containing serum reduced the levels of EGF before and after co-culture and decreased the expres-sion of EGFR,MCP-1,and MMP9 proteins before and after+co-culture.Conclusion Yanghe decoction-containing serum can inhibit the migration and invasion of breast cancer MCF-7 cells before and after co-cul-ture with M2 TAMs.This effect may be related to the inhibition of the EGF-EGFR signaling pathway.

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.

Huocao(a traditional Chinese herbal medicine) moxibustion is a characteristic technology in Yi medicine suitable for cold-dampness diseases. Huocao, as the moxibustion material, is confusedly used in clinical practice and little is known about its quality control. In this study, UPLC method was used to establish the chemical fingerprint of non-volatile components in Huocao, and the contents of eight phenolic acids such as chlorogenic acid were determined. Multivariate statistical analysis was performed to obtain the indicator components of Huocao for quality evaluation, and thus a comprehensive evaluation system for the quality of Huocao was built. The UPLC fingerprints of 49 batches of Huocao were established, and there were 20 common peaks, of which eight phenolic acids including neochlorogenic acid and chlorogenic acid were identified. Except for three batches of Huocao, the similarity of the other 46 batches was higher than 0.89, suggesting that the established fingerprint method could be used for quality control of the medicinal herb. The correlation coefficient between entropy weight score of the eight phenolic acids and comprehensive fingerprint score in Huocao was 0.875(P<0.01), which indicated that the eight phenolic acids could be used as indicator components for the quality evaluation of Huocao. Furthermore, in multivariate statistical analysis on the common peaks of fingerprint and the contents of the eight phenolic acids, chlorogenic acid, isochlorogenic acid A and isochlorogenic acid C were screened to be the indicator components. The results revealed that the proposed method achieved a simple and accurate quality control of Huocao based on UPLC fingerprint and multi-component content determination, which provided useful data for establishing the quality standard of Huocao.
