The international dissemination of Chinese acupuncture represents a successful model of medical and cultural exchange between the East and the West, as well as an exemplary case of Chinese culture going global. In 1971, following the announcement by Xinhua News Agency that "acupuncture anesthesia technology had achieved success", American medical educator Professor Edmunds Grey Dimond became the first foreign doctor to visit China for an investigation of acupuncture anesthesia. His efforts significantly contributed to the promotion of Chinese acupuncture within western medical communities. From the perspective of acupuncture humanities, this article reviews and analyzes Dimond's academic background, his journey to study acupuncture anesthesia in China, and his unique insights into acupuncture, exploring how his open-minded and objective approach facilitated the acceptance and dissemination of acupuncture anesthesia and acupuncture techniques in the West.

Objective To compare the effects of two different surgical methods in the treatment of female unilateral cT1N0-1a thyroid cancer and the satisfaction of incision cosmetics.Methods A retrospective analysis of the data of female patients with unilateral cT1N0-1a stage thyroid cancer in our hospital from October 2020 to September 2022 was conducted.They were divided into open group(65 cases)and oral group(55 cases)according to different surgical methods.Patients in open group were underwent traditional open thyroid surgery,and patients in oral group were underwent transoral vestibular approach laparoscopic thyroid surgery.Intraoperative conditions,postoperative complications and satisfaction degree of postoperative incision beauty between the two groups were comparded.Results The operation time was(124.40±11.59)minutes and the dissection time of the central lymph node was(26.44±5.33)minutes in the transoral group,which were longer than those in the open group[(65.91 ±11.44)minutes and(17.38±4.32)minutes,(P＜0.05)].Vancouver scar evaluation[(3.29± 0.96)points],patient scar evaluation[(8.62±1.57)points],observer scar evaluation[(6.67±1.17)points]and scar self-awareness score[(1.65±0.70)points]in the oral group were significantly lower than those in the open group[(5.29±1.20)points,(15.02±2.85)points,(19.57±2.94)points and(3.12±0.98)points,(P＜0.05)].There were no significant difference in the amount of blood loss,the amount of drainage,the number of days in hospital and the number of central lymph nodes dissection between the two groups(P＞0.05).There was no significant difference in total incidence of postoperative complications(hoarseness,cough after drinking water,postoperative bleeding,subcutaneous effusion)between oral group and open group(7.2％vs7.6％,P＞0.05).Conclusion The two surgical methods have their own advantages,the incidence of postoperative complications is low,safe and reliable,and the patients in the oral group are more satisfied with the cosmetology of the postoperative incision.In actual clinical work,the appropriate operation can be chosen according to the specific conditions of the patients.

Objective To evaluate the change of cardiac structure and function in patients with hypertrophic obstructive cardiomyopathy(HOCM)after ultrasound-guided percutaneous intramyocardial septal radiofrequency ablation(PIMSRA)via cardiac magnetic resonance(CMR).Methods Patients with HOCM who underwent PIMSRA,echocardiography and CMR preoperative scanning and one year after surgery were analyzed retrospectively.Myocardial structural and functional parameters were measured by Circle cardiovascular imaging post-processing software.The changes of myocardial parameters before and after surgery were compared by using paired sample t-test and Chi-square test.Results Compared with the preoperative assessment,patients'clinical symptoms and the cardiac function were significantly improved one year after surgery.The left ventricular outflow tract pressure gradient(LVOT-PG)was significantly decreased and length of mitral regurgitation was shortened one year after surgery compared with before surgery via ultrasound(P<0.05).Compared with the preoperative assessment,CMR showed that patients with end-systolic volume of left atrium,minimum volume of left atrium,transverse diameter of left atrium,thickness of ventricular septum and free wall of left ventricular at end-systolic section were significantly reduced,and left ventricular mass(LVM)was significantly decreased one year after surgery,with statistical significance between before and after surgery(P<0.001).One year after surgery,the left atrium ejection fraction(LAEF)was significantly increased(P<0.05),the maximum slope and the maximum signal intensity of the ventricular septum and the left ventricular free wall of the papillary muscle were significantly increased(P<0.001),and the peak time was significantly decreased(P<0.001)compared with before surgery.Conclusion After PIMSRA treatment,the systolic function of left atrium in HOCM patients is improved,and the microcirculation perfusion of left ventricular is significantly improved.

Objective To explore the impact of severe weather on road traffic injuries (RTIs). Methods Relevant literature on the impact of meteorology on the occurrence and resulting casualties of road traffic injuries was searched. Meta-analysis was performed on the included literature using state16.0 software. Results A total of 28 articles were included. The results of meta-analysis showed that heat wave, cloudy day, snowy day, rainy day and other severe weather such as storm had a statistically significant impact on the occurrence of road traffic injuries. Severe weather such as storms had a statistically significant impact on RTIs casualties. Conclusion Heat wave, cloudy day, snowy day, rainy day, storm and other bad weather are independent risk factors for the occurrence of RTIs. Storm is a risk factor for accident casualties. There is not enough evidence to show that low temperature, cold wave and heavy fog are the influencing factors of road traffic accidents.

Objective To systematically review the epidemiological studies on primary biliary cholangitis (PBC), and to investigate the prevalence rate of PBC in the Chinese general population and its influencing factors. Methods PubMed, Embase, The Cochrane Library, CNKI, and Wanfang Data were searched for articles on the epidemiology of PBC in China published up to 31th March 2022. Two researchers independently performed screening and data extraction, and then related analyses were performed. Results A total of 9 articles were included. The positive rate of AMA was 1 049.05/100 000 (ranging fr om 159.65/100 000 to 2287.40/100 000), and the prevalence rate of PBC was 123.68/100 000 (ranging from 42.70/100 000 to 276.59/100 000). The positive rate of AMA was 636.51/100 000 (ranging from 52.55/100 000 to 1 164.33/100 000) in men and 1 265.47/100 000 (ranging from 225.23/100 000 to 1 704.93/100 000) in women, with a male/female ratio of 1∶1.99 for the prevalence rate of AMA. The prevalence rate of PBC was 40.81/100 000 (ranging from 23.54/100 000 to 75.10/100 000) in men and 148.71/100 000 (ranging from 77.36/100 000 to 214.91/100 000) in women, with a male/female ratio of 1∶3.64 for the prevalence rate of PBC. Conclusion Different studies show great differences in the positive rate of AMA and the prevalence rate of PBC in the Chinese general population, which is mainly affected by sex, age, and region. The positive rate of AMA and the prevalence rate of PBC increase with age, and the patients aged ≥50 years have a significantly higher positive rate of AMA than those aged < 50 years. The positive rate of AMA is significantly higher than the prevalence rate of PBC. There are significantly more women than men in the AMA-positive population and the PBC patients, and the influence of sex on AMA is lower than that on PBC.

For patients with chronic hepatitis B, the indications of antiviral treatment are gradually expanding, and the pursuit of various degrees of cure (partial cure, functional cure and complete cure) is consistently improving, which enhances the urgent clinical need for improving the detection sensitivity of hepatitis B virus (HBV) surface antigen and DNA. Based on the availability of commercial highly sensitive hepatitis B surface antigen and HBV DNA detection reagents, we summarized their applications in the diagnosis of HBV infection, their role on guiding selection of antiviral treatment agents and treatment plans, their prediction efficacy and indication for drug withdrawal, their role on monitoring therapy efficacy and the prediction of disease outcomes. Taken together, highly sensitive hepatitis B virus surface antigen and DNA assays and related detection technology play an important role in the whole management process of chronic HBV infection.

Objective:To construct a porcine model of ischemia with non-obstructive coronary artery (INOCA) and explore the diagnostic value of a one-stop noninvasive method including CT myocardial perfusion imaging (CT-MPI) and coronary CT angiography (CCTA).Methods:Twelve swines were divided into the experimental group (9) and the normal group (3). Coronary microvascular dysfunction (CMD) porcine model was constructed in the experimental group by inducing diabetes mellitus, chronic kidney disease, and hypercholesterolemia. Invasive coronary angiography (ICA) and functional examination were performed on all 7+3 trial swines to clarify the INOCA diagnosis after completion of the modeling. Then, CT-MPI and CCTA were performed on all individuals to explore the CT-MPI and CCTA characteristics of INOCA porcine models. CT-MPI parameters, including myocardial blood flow (MBF), and myocardial blood volume (MBV) in rest and stress conditions, and CCTA parameters, including severity of stenosis and CAD-RADS, were analyzed.Results:ICA and functional tests showed that all swines in the experimental group met the diagnostic criteria for INOCA, which meant that INOCA porcine model was constructed successfully. CCTA results confirmed that there was no obstructive coronary stenosis in all 10 swines which were examined, which was consistent with ICA findings. CT-MPI results demonstrated that the mean MBF values, as well as the mean MBV values, in the rest and stress condition of each swines in the experimental group were lower than those of the control group. In contrast to the control group, the mean MBF and MBV values of swines in the experimental group in stress condition were generally lower than those in resting condition.Conclusions:In this study, a porcine model of CMD is successfully constructed by inducing hypercholesterolemia+diabetes mellitus+chronic kidney disease. ICA and invasive functional tests show that this CMD model meet the diagnostic criteria for INOCA. It has been confirmed that one-stop CT multimodality examination including CT-MPI and CCTA can be used for the diagnosis of INOCA as a noninvasive diagnostic method.

Objective:To explore the difference of the vessel and plaque characteristics, myocardial perfusion and cardiac function between patients with ischemia with non-obstructive coronary artery disease (INOCA) and obstructive coronary artery disease (CAD).Methods:From July 2021 to June 2022, 101 patients with angina were referred to dynamic computed tomography myocardial perfusion (CTP) and coronary computed tomography angiography (CCTA) and retrospectively included in our hospital. Based on the results of CTP and CCTA, patients were divided into INOCA (27 cases), moderate obstructive CAD (26 cases) and severe obstructive CAD (48 cases). The anatomical coronary artery stenosis, plaque characteristics and myocardial perfusion features of all patients were analyzed. Furthermore, left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), and global radial strain (GRS) were obtained on full-phase reconstruction CCTA image by using Medis Suite 3.2 postprocessing software. Multigroup analysis used one way ANOVA or Kruskal Wallis H test. Results:Patients with INOCA were younger than patients with moderate and severe obstructive CAD ( P<0.001). INOCA patients (7.4%, 2/27) had lower rate of positive remodeling than both moderate (57.7%, 15/26, P<0.001) and severe obstructive CAD patients (33.3%, 16/48, P=0.017). The percentage of ischemic myocardium volume in patients with INOCA were similar with those in patients with severe CAD (all P>0.05), but significantly higher than those in patients with moderate CAD (all P<0.05). No significant difference in terms of GLS was detected between patients with INOCA [-17.4% (-21.6%, -11.6%)] and severe CAD [-17.6% (-21.9%, -14.8%), P=0.536], however, patients both with INOCA and severe CAD also had higher GLS than patients with moderate obstructive CAD [-22.3% (-29.8%, -19.0%), all P<0.05]. Conclusions:Based on"one-stop-shop"CTP combined with CCTA imaging, early cardiac functional changes including abnormal myocardial perfusion and myocardial strain in INOCA patients were similar to those in patients with severe obstructive CAD and more severe than those in patients with moderate obstructive CAD.

Purpose To investigate the feasibility of CT-based feature tracking technology to quantify left ventricular myocardial strain(MS)and its significance in hypertrophic obstructive cardiomyopathy(HOCM).Materials and Methods A total of 35 HOCM patients who underwent cardiac coronary angiography from March 2019 to December 2021 in the First Affiliated Hospital of the Air Force Military Medical University were retrospectively included,and a total of 60 cases who were negative for cardiac coronary angiography among those who visited the hospital with suspected coronary artery disease were randomly enrolled.Conventional cardiac functional parameters and MS parameters were quantified via post-processing software,and differences of parameters between the groups were analyzed.The diagnostic efficacy of MS parameters for HOCM was further evaluated.Results Compared to the control group,the HOCM group exhibited significant increases in various conventional left ventricular functional parameters,including left ventricular wall thickness,mass,mass index,end-diastolic volume and stroke volume(t=2.119 to 24.861,all P<0.05).However,there were no statistically significant differences in end-systolic volume and cardiac output between the two groups(P>0.05).The global longitudinal and radial strain values of HOCM group were significantly lower than those of control group(t=12.857,-6.427,P<0.01),while the endocardial global circumferential strain of HOCM group was significantly higher than that of control group(t=-2.369,P<0.05).Among MS parameters,global longitudinal strain exhibited the best diagnostic efficacy for HOCM,with an area under the curve of 0.997.A cutoff value of≤20.78%for global longitudinal strain showed that the sensitivity and specificity was 100%and 95%,respectively.Conclusion The MS parameters quantified by the CT-based feature tracking technique are superior to left ventricular ejection fraction in quantifying left ventricular function,with the highest sensitivity and specificity for early myocardial function impairment of longitudinal strain.In addition,the technique has good repeatability and is expected to become a new indicator for the assessment of myocardial function in HOCM.
