Objective To construct a human health literacy indicator system for prevention of parasitic diseases based on Delphi method. Methods Based on literature reviews and expert interviews, a questionnaire was designed and a two-round Delphi consultation was performed. A human health literacy indicator system for prevention of parasitic diseases was constructed according to the deletion criteria and experts’ advice. Results A total of 14 experts completed the two-round consultation. The second-round authority coefficients were 0.91 to 0.96 for the first-level indicators, 0.87 to 0.97 for the second-level indicators and 0.86 to 0.97 for the third-level indicators. A human health literacy indicator system for prevention of parasitic diseases was constructed with the main framework of basic knowledge and awareness, healthy behaviors, and healthy skills, which contained 3 first-level indicators, 12 second-level indicators and 48 third-level indicators. Among the three first-level indicators, basic knowledge and awareness had the highest weighting coefficient (0.336 5), followed by healthy behaviors (0.334 9), and healthy skills had the lowest weighting coefficient (0.328 6). The three secondary-level indicators with the highest combined weights included awareness of the epidemic status (0.088 2), awareness of the resource of infection (0.085 8) and basic awareness of parasitic diseases (0.085 5). Conclusion A human health literacy indicator system for prevention of parasitic diseases is preliminarily constructed, which provides insights into the development of health literacy evaluation tools for prevention of parasitic diseases in the new era.

Incremental value of epicardial fat volume on predicting obstructive coronary artery disease with myocardial ischemia / 中华心血管病杂志

Objective: This study aimed to investigate the association between epicardial fat volume (EFV) and obstructive coronary artery disease (CAD) with myocardial ischemia, and evaluate the incremental value of EFV on top of traditional risk factors and coronary artery calcium (CAC) in predicting obstructive CAD with myocardial ischemia. Methods: This study was a retrospective cross-sectional study. Patients with suspected CAD who underwent coronary angiography (CAG) and single photon emission computerized tomography-myocardial perfusion imaging (SPECT-MPI) at the Third Affiliated Hospital of Soochow University from March 2018 to November 2019 were consecutively enrolled. EFV and CAC were measured by non-contrast chest computed tomography (CT) scan. Obstructive CAD was defined as coronary artery stenosis≥50% in at least one of the major epicardial coronary arteries, and myocardial ischemia was defined as reversible perfusion defects in stress and rest MPI. Obstructive CAD with myocardial ischemia was defined in patients with coronary stenosis severity≥50% and reversible perfusion defects in the corresponding areas of SPECT-MPI. Patients with myocardial ischemia bot without obstructive CAD were defined as none-obstructive CAD with myocardial ischemia group. We collected and compared the general clinical data, CAC and EFV between the two groups. Multivariable logistic regression analysis was performed to identify the relationship between EFV and obstructive CAD with myocardial ischemia. ROC curves were performed to determine whether addition of EFV improved predictive value beyond traditional risk factors and CAC for obstructive CAD with myocardial ischemia. Results: Among the 164 patients with suspected CAD, 111 patients were males, and average age was (61.4±9.9) years old. 62 (37.8%) patients were included into the obstructive CAD with myocardial ischemia group. 102 (62.2%) patients were included into the none-obstructive CAD with myocardial ischemia group. EFV was significantly higher in obstructive CAD with myocardial ischemia group than in none-obstructive CAD with myocardial ischemia group ((135.63±33.29)cm3 and (105.18±31.16)cm3, P<0.01). Univariate regression analysis showed the risk of obstructive CAD with myocardial ischemia increased by 1.96 times for each SD increase in EFV(OR 2.96; 95%CI, 1.89-4.62; P<0.01). After adjustment for traditional risk factors and CAC, EFV remained as an independent predictor for obstructive CAD with myocardial ischemia (OR, 4.48, 95%CI, 2.17-9.23; P<0.01). Addition of EFV to CAC and traditional risk factors was related to larger AUC for predicting obstructive CAD with myocardial ischemia (0.90 vs. 0.85, P=0.04, 95%CI: 0.85-0.95) and the global chi-square increased by 21.81 (P<0.05). Conclusions: EFV is an independent predictor for obstructive CAD with myocardial ischemia. Addition of EFV to traditional risk factors and CAC has incremental value for predicting obstructive CAD with myocardial ischemia in this patient cohort.

Objective:To compare and analyze the pricing units and prices of traditional Chinese medicine (TCM) medical services in 4 provinces of the Yangtze River Delta, for reference for the integrated development of TCM medical service project setting and price coordination in the Yangtze River Delta region.Methods:The medical service price project specifications published on the official websites of relevant departments in 4 provinces of the Yangtze River Delta (updated to March 2022) were obtained to extract data such as project names and pricing units. The pricing units and prices of TCM medical service projects in each province were compared and analyzed; The Jevons index method was used to analyze comparable project prices.Results:The numbers of TCM medical service projects in Shanghai, Jiangsu, Zhejiang, and Anhui were 113, 146, 117, and 198, respectively. The types of pricing units were 15, 24, 13, and 12, respectively. There were differences in the setting of pricing units, especially in acupuncture and moxibustion, which had more decomposition projects. The average price of overall medical services in the Yangtze River Delta was 9.81 times that of TCM medical services. There were differences in the prices of comparable TCM medical service projects among the four provinces. Based on Anhui province, the inter provincial Jevons index of other categories of TCM medical service projects except for TCM massage were all less than 1.00.Conclusions:There were significant differences in the pricing units and prices of TCM medical service projects in the four provinces of the Yangtze River Delta, with Anhui province having the most significant difference compared to the other three provinces; The overall price of TCM medical service projects was relatively low.

Assessment of left ventricular diastolic dyssynchrony and its influencing factors early after acute myocardial infarction by SPECT gated myocardial perfusion imaging: an experimental study / 中华核医学与分子影像杂志

Objective:To evaluate the left ventricular diastolic dyssynchrony (LVDD) and its influencing factors early after acute myocardial infarction (AMI) using phase analysis of SPECT gated myocardial perfusion imaging (GMPI).Methods:Bama miniature swines ( n=16) were subjected to establish AMI models. GMPI was performed before and 1 d after AMI to obtain the extent of myocardial perfusion defect (Extent, %) and left ventricular systolic dyssynchrony (LVSD)/LVDD parameters, namely the phase histogram bandwidth (PBW) and phase standard deviation (PSD). Meanwhile, left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), and the ratio of early to late peak mitral diastolic flow (E/A) were obtained by echocardiography. Independent-sample t test, paired t test and Pearson correlation analysis were used to analyze the data. Results:Sixteen AMI swines were successfully created. Compared to baseline, Extent, LVEDV and LVESV significantly increased on 1 d after AMI ( t values: -11.14, -4.55, -6.12, all P<0.001), while LVEF and E/A significantly decreased ( t values: 10.16, 2.18, P<0.001, P=0.046). GMPI showed that the LVDD parameters PBW and PSD increased significantly on 1 d after AMI when compared to those at baseline((142.25±72.06)° vs (33.06±8.98)°, (56.15±26.71)° vs (12.51±5.13)°; t values: -6.11, -6.60, both P<0.001). There were significant differences between LVSD parameters and LVDD parameters (PBW: (109.06±62.40)° vs (142.25±72.06)°, PSD: (44.40±25.61)° vs (56.15±26.71)°; t values: -2.73, -2.20, P values: 0.016, 0.044). LVDD parameters PBW, PSD were negatively correlated with E/A after AMI ( r values: -0.569, -0.566, P values: 0.021, 0.022), and positively correlated with the Extent ( r values: 0.717, 0.634, P values: 0.002, 0.008). The phase analysis of SPECT GMPI to evaluate LVDD showed good intra-observer and inter-observe reproducibility (intraclass correlation coefficient (ICC): 0.953-0.984, all P<0.001). Conclusions:LVDD occurs early on 1 d after AMI, and can reflect left ventricular diastolic dysfunction. The Extent is correlated with LVDD significantly. Phase analysis of SPECT GMPI is an accurate method to evaluate LVDD and left ventricular diastolic function.

Time to initial diagnosis of imported malaria and its influencing factors in Jiangsu Province / 中国血吸虫病防治杂志

Objective To investigate the health-seeking behaviors of imported malaria cases after returning to China, and to investigate the factors affecting the time to initial diagnosis, so as to provide the scientific evidence for early identification of imported malaria cases and prevention of severe cases development and secondary transmission. Methods The individual demographic features, and the disease onset and the time to initial diagnosis of imported malaria cases in Jiangsu Province in 2019 were captured from the National Notifiable Disease Report System and the Information Management System for Parasitic Disease Control in China. The characteristics of health-seeking behaviors and epidemiological features of imported malaria cases were descriptively analyzed, and the factors affecting the time to initial diagnosis of imported malaria cases after returning to China were identified using multivariate logistic regression analysis. Results A total of 244 imported malaria cases were reported in Jiangsu Province in 2019, and the time to initial diagnosis of the cases were 1-12 days, with mean time of (1.53 ± 1.65) days, with median time of one day. The highest number of malaria cases seeking healthcare services were found on the day of developing primary symptoms (76 cases, 31.1%), followed by on the second day (68 cases, 27.9%), on the third day (46 cases, 18.9%), and 54 cases (22.1%) received initial diagnosis 3 days following presence of primary symptoms, including 3 cases with initial diagnosis at more than one week. High proportions of imported malaria cases with a delay in the time to initial diagnosis were seen in migrant workers who returned to China in January (14 cases, 5.7%) and December (13 cases, 5.3%) and those aged between 41 and 50 years (32 cases, 13.1%). Multivariate logistic regression analysis showed relative short time to initial diagnosis among imported malaria cases returning to China on March [odds ratio (OR) = 0.16, P = 0.03, 95% confidence interval (CI): (0.03, 0.85)] and those with a history of overseas malaria parasite infections [OR = 0.36, P = 0.001, 95% CI: (0.19, 0.67)]. Conclusions Timely health-seeking behaviors should be improved among imported malaria cases in Jiangsu Province, patients with a history of overseas malaria infections require faster health-seeking activities.

Analysis on the current situation of medical service price from the perspective of medical insurance integration in the Yangtze River Delta / 中华医院管理杂志

Objective:To sort out the medical service price management in provinces of the Yangtze River Delta, and identify problems in the process of promoting the integration of medical insurance in the said region.Methods:The service price reform policies and current medical service price items specifications as of December 2020 were collected from the official websites of the reform and developmet committees, health comissions and health insurane bureaus of these provinces. Descriptive analysis using R 4.0.2 software were conducted.Results:Given the reform of medical service prices advanced in these provinces successively, the current medical service price items were not yet unified. In terms of the numbers, Jiangsu topped the rest by 4 457 basic items, while Zhejiang ranked the lowest at 3 914. In terms of decomposed items, Zhejiang topped the rest by 1 988, 17.6 times that of Anhui province. In terms of pricing level, the average price of medical services in Shanghai topped the rest by 1 041.6 yuan, while Jiangsu province was the lowest at 768.6 yuan. The price of some items varied by more than 20 times among these provinces.Conclusions:The provinces in the Yangtze River Delta had significant gaps in medical service price items setup and price levels. It is necessary to promote the regional coordinated specifications of medical service price items, further optimize the price levels, improve the methodological system of medical service price comparison, and promote the integration of medical insurance in the Yangtze River Delta.

Status quo and countermeasures of the new medical service price items management in China / 中华医院管理杂志

New medical service price items (hereinafter referred to as the new item) management is key to deepening medical service price reform.Based on the review of the policy development of the new item management and status quo of provincial-level practices, the authors sorted out the problems in the new item management as follows. Namely the new item connotation was not clearly defined, linkage with the national specifications for medical service price items was not yet well defined, the approval process was imperfect, the pricing fundamentals were weak, and the maturity term system was to be strengthened. According to such analyses, the authors proposed countermeasure recommendations for optimizing the new item management: to introduce and implement unified national specifications for medical service price item and the new item guidance as quickly as possible, to promote the linkage between the new item management and the dynamic adjustment mechanism of medical service prices, and to strengthen institutional construction of the new item management.

Value of 18F-FDG PET/CT metabolic parameters of primary lesions for predicting occult lymph node metastasis in non-small cell lung cancer / 中华核医学与分子影像杂志

Objective:To investigate the predictive value of 18F-fluorodeoxyglucose (FDG) PET/CT metabolic parameters for occult lymph node metastasis (OLM) in non-small cell lung cancer (NSCLC). Methods:A total of 183 patients (72 males, 111 females; age (61.5±8.4) years) who underwent 18F-FDG PET/CT and preoperatively diagnosed with clinical N0 stage (cN0) in Third Affiliated Hospital of Soochow University from January 2013 to December 2018 were retrospectively enrolled. All patients underwent anatomical pulmonary resection with systematic lymph node dissections within 3 weeks after 18F-FDG PET/CT examinations. According to the presence or absence of lymph node metastasis, patients were divided into OLM positive (OLM+ ) group and OLM negative (OLM-) group. Parameters of primary lesions, such as the maximum diameter (D max), tumor sites, morphological features, maximum standardized uptake value (SUV max), mean standardized uptake value (SUV mean), metabolic total volume (MTV), total lesion glycolysis (TLG), tumor SUV max to liver SUV mean (TLR max), tumor TLG to liver SUV mean (TLR TLG) were analyzed. Mann-Whitney U test and χ2 test were used to compare the parameters between groups. Multivariable logistic regression was used to analyze the independent risk factors for OLM. Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic value of different parameters. Results:Among 183 patients, 25 (13.7%, 25/183) of them were diagnosed as OLM. In OLM+ group, 46 lymph nodes were pathologically positive for metastasis, including 15 N1 disease and 31 N2 disease. D max (2.9(2.3, 3.7) vs 2.3(1.7, 2.8) cm), lobulation ((76.0%(19/25) vs 37.3%(59/158)), SUV max (11.1(7.9, 17.7) vs 4.7(2.3, 9.2)), TLG (41.5(10.2, 91.1) vs 15.6(6.5, 23.8) ml), TLR max (4.7(3.5, 7.6) vs 2.1(0.9, 4.0)) and TLR TLG (18.1(5.0, 44.3) vs 6.1(3.0, 11.4) ml) of the primary lesions in OLM+ group were significantly higher than those in OLM-group ( z values: from -4.709 to -3.247, χ2=13.190, all P<0.05). Multivariable logistic regression analysis showed that TLR max (odds ratio ( OR)=15.145, 95% CI: 3.381-67.830, P<0.001) and D max ( OR=3.220, 95% CI: 1.192-8.701, P=0.021) were independent risk factors for OLM. TLR max yielded the highest area under curve (AUC; AUC=0.794) with the threshold of 3.12, and the sensitivity, specificity, accuracy, positive predictive value and negative predictive value for predicting OLM were 92.0%(23/25), 63.3%(100/158), 67.2%(123/183), 28.4%(23/81) and 98.0%(100/102), respectively. Conclusions:TLR max of tumor is the independent risk factor for OLM in NSCLC patients. TLR max can sensitively predict OLM preoperatively in patients with NSCLC.

Latest Progresses in Surgical Treatment of Median Arcuate Ligament Syndrome / 中国医学科学院学报

Median arcuate ligament syndrome(MALS)is compression of the celiac trunk by the median arcuate ligament.Median arcuate ligament release is the corner stone for the surgical treatment of MALS.Open surgery,laparoscopic surgery,and robot-assisted surgery have been developed,among which laparoscopic surgery has been proposed as the preferred approach in view of its minimal trauma and short hospital stay.Auxiliary celiac plexus neurolysis could further alleviate the patient's discomfort.Moreover,vascular reconstitution is of vital importance in the case of persistent stenosis in the celiac artery despite of median arcuate ligament decompression.Vascular reconstruction has satisfactory long-term patency rate,while endovascular treatment is less invasive.This article aims to summarize the consensuses and advances and shed light on the surgical treatment of MALS.

Correlation study between T lymphocyte-related cytokines and the outcome of chronic immune thrombocytopenia in children / 中华实用儿科临床杂志

Objective:To detect the levels of cytokines in peripheral blood of patients with chronic immune thrombocytopenia (ITP) and analyze their significance in the clinical prognosis of children with chronic ITP.Methods:Thirty patients with chronic ITP who were treated in the Department of Pediatrics, the First Affiliated Hospital of Xinxiang Medical Univercity from October 2015 to October 2018 were followed and enrolled in the experimental group and 40 healthy children in the same hospital were enrolled in the healthy control group.The levels of interleukin-2(IL-2), interferon-γ(IFN-γ), tumor necrosis factor(TNF), interleukin-4(IL-4), interleukin-6(IL-6), interleukin-10(IL-10) and interleukin-17A(IL-17A) in the experimental group and the healthy control group were detected by flow cytometry (CBA). The relationship between cytokines and prognosis of children with chronic ITP were analyzed.Results:Thirty patients with ITP were enrolled. The expressions of IL-2 and IL-17A in the experimental group before treatment were (7.86±3.90) ng/L and (10.45±12.35) ng/L, while those of IL-2 and IL-17A in the healthy control group were (3.11±2.41) ng/L and (2.97±7.04) ng/L. The levels of IL-2 and IL-17A in the experimental group were significantly higher than those in the healthy control group, and the differences were statistically significant ( t=-7.123, -5.582, all P<0.01). The expressions of IL-4 and IL-10 in the experimental group before treatment were (0.38±0.25) ng/L and (1.80±1.25) ng/L, while those of IL-4 and IL-10 in the healthy control group were (3.08±0.26) ng/L and (4.55±3.44) ng/L. The levels of IL-4 and IL-10 in the experimental group were significantly lower than those in the healthy control group, and the differences were statistically significant ( t=8.400, 5.653, all P<0.01). The expressions of IL-6, TNF and IFN-γ in the experimental group before treatment were (7.30±9.16) ng/L, (4.85±7.60) ng/L and (7.68±20.41) ng/L, while those of IL-6, TNF and IFN-γ in the healthy control group were (5.44±4.18) ng/L, (1.97±0.37) ng/L, (4.81±17.71) ng/L. There was no significant difference between the two groups ( P>0.05), and no significant difference in the levels of cytokines between the patients with chronic ITP before and 12 months after treatment ( P>0.05). Conclusions:The changes of T lymphocyte related cytokines are closely related to the pathogenesis and development of chronic ITP in children. There may be persistent immune dysfunction in children with chronic ITP. Dynamic monitoring of cytokines IL-2, IL-4, IL-10, IL-17A, especially IL-17A, is helpful to judge the prognosis of ITP in children, and may be of guiding significance in evaluating clinical prognosis.

Acupuncture has been widely used for treating diseases since the ancient days in China, but the mechanism by which acupuncture exerts such powerful roles is unclear. Epigenetics, including DNA methylation, histone modification, and post-transcriptional regulation of miRNAs, is the study of heritable changes in gene expression that do not include DNA sequence alterations. Epigenetics has become a new strategy for the basic and clinical research of acupuncture in the last decade. Some investigators have been trying to illustrate the mechanism of acupuncture from an epigenetics perspective, which has shed new lights on the mechanisms and applications of acupuncture. Moreover, the introduction of epigenetics into the regulatory mechanism in acupuncture treatment has provided more objective and scientific support for acupuncture theories and brought new opportunities for the improvement of acupuncture studies. In this paper, we reviewed the literatures that has demonstrated that acupuncture could directly or indirectly affect epigenetics, in order to highlight the progress of acupuncture studies correlated to epigenetic regulations. We do have to disclose that the current evidence in this review is not enough to cover all the complex interactions between multiple epigenetic modifications and their regulations. However, the up-to-date results can help us to better understand acupuncture's clinical applications and laboratory research.

Impact of the Timing of Traditional Chinese Medicine Therapy on the Therapeutic Effect and Prognosis of Severe Coronavirus Disease 2019 / 中国医学科学院学报

To explore the optimal therapy time for the treatment of severe coronavirus disease 2019(COVID-19)by traditional Chinese medicine(TCM)and its influence on the therapeutic effect and prognosis. The clinical data,laboratory findings,and outcomes of 64 patients with severe COVID-19 treated with TCM and western medicine in Chongqing from January 20,2020, to March 11,2020 were retrospectively analyzed.Patients were divided into early intervention group[TCM was initiated within 3 days (including day 3) after the first diagnosis of severe type/critical type COVID-19]and late intervention group[TCM was initiated after 7 days (including day 7) after the first diagnosis of severe type /critical type COVID-19].The changes in clinical parameters during the course of disease were compared between the two groups. On day 14,the oxygenation index was 292.5(252.0,351.0)mmHg in the early intervention group,which was significantly higher than that in the late intervention group [246.0(170.0,292.5)mmHg](=0.005).The length of hospital stay [(18.56±1.11)d (24.87±1.64)d,=0.001],duration of ICU stay [(14.12±0.91)d (20.00±1.53)d,=0.000] and time to negativity [(16.77±1.04)d (22.48±1.66)d,=0.001] in the early intervention group were significantly shorter than those in the late intervention group.The intubation rate(7.3%)in the early intervention group was significantly lower than that in the late intervention group(30.4%)(=0.028). Early TCM therapy within three days after a diagnosis of severe COVID-19 can shorten the length of hospital stay,duration of ICU stay,and time to negativity and decrease intubation rate.
