Based on commonly used acupoints in the clinical acupuncture treatment of functional dyspepsia （FD）， this study systematically analyzes the therapeutic differences and synergistic effects between local and distal point selection. It also examines the suitability of primary acupoint selection for different FD subtypes， postprandial distress syndrome （PDS） and epigastric pain syndrome （EPS）. The findings suggest that a combination of local and distal acupoints may be more appropriate as primary points for PDS， whereas local acupoints alone may be more suitable for EPS. Additionally， the study explores the impact of various factors， such as stimulation techniques， needling order， intensity or stimulation parameters， and depth， on the efficacy of acupuncture. It concludes that the intrinsic properties of acupoints are the primary determinants of therapeutic direction. Other factors mainly influence the magnitude rather than the direction of the effect. Future research may further investigate how different acupoint combinations， local versus distal， affect the treatment outcomes of FD subtypes， providing new insights for clinical acupuncture prescriptions.

The apprenticeship education of Traditional Chinese medicine(TCM)is an important pathway for the cultivation of talents in TCM education.The combination of institutional education and apprenticeship education is considered to be the most suitable educational model that aligns with the inherent characteristics of TCM education.The current status of TCM education in western medical institutions and the main challenges include the difficulty in transitioning between western and Chinese medical reasoning and limited clinical internship hours for TCM.The strengths and features of TCM apprenticeship education lie in cultural heritage,classical teachings,mentorship,practice orientation and personalized education.Therefore,integration of TCM apprenticeship education and clinical internships for western medical students represents a new educational model for medical undergraduates.

As the continuation of the left ventricle,the left atrium and left ventricle interact and play an important role in the function of the whole heart.At present,there are many techniques to evaluate the atrial structure and function,but the left atrial structure is complex and the myocardium is thin,which brings some challenges to the relevant evaluation.This paper introduces the parameters,precautions and relevant clinical applications in the process of left atrial evaluation from the aspects of myocardial strain and delayed enhancement.

Purpose To explore the influence of different spin-locking frequencies on T1ρ values based on a 3.0T MR system.Materials and Methods Thirty-eight healthy adult volunteers underwent cardiac magnetic resonance imaging at the First Affiliated Hospital of Anhui Medical University from July to September 2023.T1ρ mapping and short-axis cine imaging with steady-state free precession sequences were performed with 3.0T MR system.T1ρ mapping sequence in three short-axis slices with three spin-lock frequencies at the amplitude of 5 Hz,300 Hz,400 Hz,and 500 Hz was scanned,respectively.T1ρ relaxation times and myocardial fibrosis index were quantified for each slice and each myocardial segment,the difference in T1ρ of different spin-locking frequencies and myocardial fibrosis index was analyzed using one-way repeated-measures analysis of variance method.Results T1ρ of 5 Hz,300 Hz,400 Hz,and 500 Hz were(33.9±2.8)ms,(43.4±2.1)ms,(45.4±2.6)ms and(46.5±2.4)ms,respectively;and T1ρ values showed a significant progressive increase from the low spin-lock frequency to the high spin-lock frequency of the heart(300 Hz vs.400 Hz:P<0.001;300 Hz vs.500 Hz:P<0.001;400 Hz vs.500 Hz:P=0.043).In addition,the measured myocardial fibrosis index at 300 Hz,400 Hz and 500 Hz were(9.4±2.2)ms,(11.3±2.9)ms and(12.6±2.7)ms,respectively.Statistical analysis underscored significant variations among these measurements(300 Hz vs.400 Hz:P<0.001;300 Hz vs.500 Hz:P<0.001;400 Hz vs.500 Hz:P=0.033).Conclusion In this prospective study,myocardial T1ρ values for the specific cardiac magnetic resonance setting are provided,and we found that spin-lock frequency can affect the T1ρ values.

The study aimed to analyze the efficacy and safety of rituximab in the treatment of 23 cases of lupus nephritis and explore the prospect of half-dose rituximab in lupus nephritis treatment. Twenty-three patients with lupus nephritis hospitalized in the Department of Rheumatology and Immunology at the First Medical Center of the PLA General Hospital from May 2013 to December 2021 were selected. Eighteen patients received rituximab 375 mg/m 2 on the first and 14th days, 5 patients received 500 mg of rituximab on the first and 14th days, and rituximab was used as needed 6 months later. Methylprednisolone (80-120 mg) was given together with rituximab. Afterward, 1 mg/kg prednisone was used for 4 weeks, which was progressively tapered to maintenance doses or discontinued. B lymphocyte level, renal function, 24-h urine protein level, and systemic lupus erythematosus (SLE) disease activity index 2000 (SLEDAI2K) score before and after treatment were recorded. The efficacy and adverse reactions were analyzed. The results showed that 11 patients suffered from renal insufficiency [creatinine (162.7±58.6) μmol/L ] at baseline, while the creatinine level of 9 patients returned to normal 12 months after the treatment [ (66.3±10.1)μmol/L ]. Normal renal function of the other 12 patients was maintained during treatment. After 12 months, the 24-h urine protein level decreased from 4.00 (2.00,6.80) g in the baseline period to 0.10 (0.08,0.40) g. SLEDAI2K score decreased from 22 (18,26) in the baseline period to 3 (0,6) 12 months after the treatment. The B lymphocyte level reached 0.00 (0.00,0.01)% at 3 months. Of 23 patients, 13 patients achieved complete remission, and 7 patients achieved partial remission after 6 months of rituximab treatment. Five patients experienced adverse reactions related to rituximab, including 1 case of transfusion reaction, 1 case of perioral herpes with pulmonary infection, and 3 cases of decreased IgG levels. Therefore, rituximab regimen used in this study can be an effective treatment strategy for lupus nephritis.

Objective:To evaluate the therapeutic effect of excimer laser ablation (ELA) in the treatment of lower extremity arterial ischemic diseases.Methods:The clinical data of 44 patients with lower extremity ischemic diseases treated with ELA in the People′s Hospital of Xinjiang Uygur Autonomous Region from December 2020 to April 2021 were analyzed retrospectively. Among the 44 patients, there were 29 patients in lower extremity arteriosclerosis obliterans (ASO), including 3 patients with femoral artery stent occlusion. 8 patients of diabetes foot (DF) and 7 patients of thromboangiitis obliterans (TAO). Observation indicators include target vascular patency rate, amputation rate, vascular reintervention rate and mortality rate. The measurement data were expressed as mean ± standard deviation ( ± s), one-way analysis of variance was used for inter-group comparison, and paired sample t-test was used for intra-group comparison. The Chi-square test was used for comparison between count data. Results:The success rate of operation was 100% in 44 patients. The rate of major amputation in ASO group was 10.3%, while the other two groups had a major amputation rate of 0. The minor amputation rates of the three groups were 6.9%, 25.0% and 28.6%, respectively. The vascular reintervention rate was 10.3% in ASO group, 12.5% in DF group and 0 in TAO group. The 1-year mortality rate in the ASO group was 10.3%, while the other two groups had a mortality rate of 0. The 2-year mortality rate of the three group were 31.0%, 12.5% and 0, respectively.Conclusion:For the treatment of lower extremity arterial ischemic diseases, ELA is safe and effective, but the curative effect need to further clarify by large sample and long-term clinical follow-up observation.

Objective:To explore the optimal acceleration factor and feasibility of the compressed SENSE (CS) technique in non-contrast MR coronary angiography (NMRCA) for clinical practice.Methods:The image data of completed coronary CTA and 3.0 T NMRCA sequence in 31 patients with suspected coronary heart disease were prospectively recruited at Fuyang People′s Hospital from August 2021 to November 2021. NMRCA sequences included conventional SENSE2 sequence and CS sequences with acceleration factors of 4, 5, and 6, respectively. The subjective scores of image quality and the objective scores, the contrast ratios between assessed coronaries and myocardium (CMCR) were compared among the 4 groups using the Friedman and Wilcoxon rank sum test.Results:Compared with the conventional SENSE2 [(343±46)s], the scan time of CS4 (269±36), CS5 (214±29) and CS6 (178±26) s were shortened by 21.5%, 37.5% and 48.0%, respectively. There was a good consistency between the subjective scores of the four groups (Kappa=0.769, 95% Cl 0.738-0.800). There was no significant difference in subjective score and CMCR value between CS4 and SENSE2 ( P>0.05). The coronary artery segments of CS5 and CS6 were significantly different from SENSE2 group ( P<0.05). Conclusions:For 3.0 T NMRCA, CS technology shows high feasibility. The CS4 can reduce imaging time while ensuring high-quality coronary arterial images, which has a well-established clinical application value for NMRCA.

Ureteral calculi after lingual mucosal ureteral reconstruction are rare. In this paper, we reported a case of a male patient who had undergone robotic-assisted laparoscopic lingual mucosal right ureteroplasty. Calculi were found in the right reconstructed ureteral segment 4 months after surgery. Then the patient underwent transurethral ureteroscopic holmium laser lithotripsy combined with a stone retrieval basket, and postoperative urological CT showed no residual calculi in the right ureter. No recurrence of right ureteral calculi or complications were observed during 20 months of follow-up.

Objective: To evaluate the accuracy and feasibility of coronary artery calcium score ( CACS) on virtual non-contrast scan ( VNC) images obtained from coronary artery CT angiography ( CCTA) scan with dual －layer spectral detector CT (SDCT) ． Methods : The data of 197 patients who underwent CCTA scan in hospital were analyzed retrospectively，and 88 patients with CACS ＞0 were further analyzed． Linear regression analysis of CACS and coronary artery calcium volume ( CACV) of true non-contrast (TNC) images and VNC images ( CACS-TNC， CACS-VNC，CACV-TNC，CACV-VNC) was performed to obtain linear regression equation and correction coefficients λ 1AVG and λ2AVG ．CACS-VNC and CACV-VNC were corrected by the corresponding regression equation and recorded as CCACS-VNC and CCACV-VNC，respectively．Spearman correlation coefficient was used for correlation analysis and Bland-Altman plot was used for consistency test．Mann-Whitney U test was used to compare the difference between the two groups. Results : For the total coronary artery，there was a strong correlation between CACS- TNC and CACS-VNC (rs = 0. 952，P ＜0. 001 ，λ 1AVG = 2. 19 ) ，CACV-TNC and CACV-VNC ( rs = 0. 954，P < 0. 001，λ2AVG = 1. 93) ．The results of Mann-Whitney U test showed that there was no significant difference between CACS-TNC and CCACS-VNC or between CACV-TNC and CCACV-VNC，and the Bland-Altman plot showed good consistency between CACS-TNC and CCACS-VNC ，CACV-TNC and CCACV-VNC． Conclusion VNC images based on SDCT can accurately measure CACS and be used for cardiovascular risk classification，which is expected to replace TNC scan and reduce the radiation dose of patients.

Objective:To explore whether left ventricular interstitial fibrosis is associated with left atrial enlargement and left atrial dysfunction in patients of hypertrophic cardiomyopathy(HCM) with preserved ejection fraction.Methods:From October 2018 to September 2021, 59 HCM including 30 with enlarged maximal left artrial volume index (LAVI max), 29 with normal LAVI max and 28 age-and gender-matched controls were retrospectively enrolled. Imaging protocol included cine sequence, late gadolinium enhancement and T 1 mapping.The relationships between left ventricular mass index (LVMI), quantitative myocardial fibrosis and left atrial-related indexes were analyzed. One-way analysis of variance with Bonferroni post hoc correction or Kruskal-Wallis was performed for continuous variables. Categorical variables were assessed using the Chi-square test or Fisher′s exact test. Pearson or Spearman analysis was used for linear or monotonic nonlinear correlations. Results:The left ventricular end-diastolic volume index, left ventricular end-systolic volume index, left ventricular cardiac output and LVMI of HCM with enlarged LAVI max group were higher than HCM with normal LAVI max group and control group( P<0.05).Correlation analysis showed that LVMI correlated positively with LAVI max( r=0.780, P<0.001) and minimal left artrial volume index (LAVI min) ( r=0.816, P<0.001), extracellular volume correlated positively with LAVI max( r=0.462, P<0.001) and LAVI min( r=0.483, P<0.001),%LGE was correlated positively with LAVI max( r=0.311, P<0.05) and LAVI min( r=0.327, P<0.05),left ventricular index interstitial volume was correlated negatively with left atrial ejection fraction of reservoir ( r=-0.669, P<0.001),left atrial ejection fraction of conduit ( r=-0.472, P<0.001),left atrial ejection fraction of pump ( r=-0.518, P<0.001)and left atrial expansion index( r=-0.626, P<0.001). Conclusion:There is association between LVMI and fibrosis and left atrial enlargement and phases dysfunction in HCM with preserved ejection fraction.
