OBJECTIVETo explore the protective mechanism of electroacupuncture (EA) at "Neiguan" (PC 6) on ischemic myocardial injury, and to explain the response patterns and characteristics of the specific effect of acupoints along meridians in sodium channel in the level of cardiac organ.

METHODSA total of 60 SPF male rats were randomly divided into a blank group, a model group, a non-acupoint group, a Neiguan group and a Lieque group, 12 cases in each one. Except the blank group, rats in the remaining group were treated with subcutaneous injection of isoprenaline to establish the model of myocardial ischemia. Rats in the Neiguan group, Lieque group and non- acupoint group were treated with EA, dilatational wave, with a frequency of 2 Hz/20 Hz. The intensity was 2-3 mA. The needles were retained for 20 min per time, once a day for consecutive 7 days. In the blank group and control group, the rats were grasped and fixed at the treating time each day. The western-blot method was used to test the expression of voltage-gated sodium channel alpha subunit (Nav 1.5), protein tyrosine kinase (PTKs) and protein tyrosine phosphatase (PTPs).

RESULTSThe expression of Nav 1.5 and PTKs in the model group was lower than that in the blank group (both P<0. 01); the expression in the Neiguan group and Lieque group was higher than that in the model group (all P < 0.01); the expression of Nav 1.5 and PTKs in the Neiguan group was higher than that in the Lieque group (both P < 0.01). The expression of PTPs in the model group and non-acupoint group was higher than that in the blank group (both P < 0.01); the expression of PTPs in the Neiguan group and Lieque group was significantly down-regulated, which was lower than the model group (both P < 0.01); the down-regulation in the Neiguan group was significantly different from that in the Lieque group (P < 0.05).

CONCLUSIONEA at "Neiguan" (PC 6), by down-regulating the expression of PTPs, up-regulating the expression of Nav 1.5 and PTKs, is likely to achieve the aim of regulation on sodium channel activity and calcium overload, further to improve myocardial ischemia, which provides experimental basis for the theory of the specific effect of acupoints along meridians.

Objective:To explore the diagnostic performance of ultrasound attenuation imaging (ATI) in grading the degree of hepatic steatosis in metabolic dysfunction-associated fatty liver disease (MAFLD).Methods:The liver gray-scale ultrasound and ATI examinations were performed on 212 subjects who were treated in Zhongshan Hospital Affiliated to Fudan University from August 2020 to March 2021. The attenuation coefficient(AC) values among different degrees of hepatic steatosis were analyzed and the diagnostic performance of ATI was evaluated. Relationships between AC values and clinical characteristics were assessed by Pearson′s correlation analysis.Results:The AC values for normal liver, mild, moderate and severe fatty liver were (0.56±0.05)dB·cm -1·MHz -1, (0.68±0.09)dB·cm -1·MHz -1, (0.82±0.09)dB·cm -1·MHz -1, (0.94±0.09)dB·cm -1·MHz -1, respectively. There were significant differences in AC values among different hepatic steatosis divisions( P<0.008). There was highly significant correlation between AC values and the degree of hepatic steatosis( r=0.860, P<0.01), moderate correlation between AC values and BMI( r=0.425, P<0.01), weak correlation between AC values and HDL-C( r=-0.237, P=0.029), no correlations between AC values and age, TC, TG, LDL-C ( r=0.083, 0.055, 0.133, -0.039, all P>0.05) .The areas under the receiver operating characteristics curve of ATI for mild fatty liver and above, moderate fatty liver and above, severe fatty liver and above were 0.958, 0.962, 0.918; the sensitivity were 90.1%, 95.8%, 94.9%, the specificity were 96.1%, 87.1%, 73.9%, and the cut-off values were 0.666 dB·cm -1·MHz -1, 0.719 dB·cm -1·MHz -1, 0.803 dB·cm -1·MHz -1, respectively. Conclusions:ATI is a reliable and convenient method for evaluating the degree of hepatic steatosis in MAFLD.

Objective:To analyze the viscosity characteristics of liver tumors and investigate the clinical value of shear wave dispersion (SWD) in the differentiation of benign and malignant liver tumors.Methods:A total of 103 patients with focal liver lesions were prospectively collected in Zhongshan Hospital Affiliated to Fudan University from October 2020 to July 2021, including 80 cases with single lesion and 23 cases with multiple lesions, and only the largest lesion was observed in patients with multiple lesions. SWD values were measured within the tumor and in the liver parenchyma 2 cm away from the tumor, and were compared between benign tumor group and maligant tumor group. The ROC curves of SWD value, SWD ratio and their combination in differentiating benign and malignant liver tumors were plotted respectively, and the optimal diagnostic threshold, the sensitivity, specificity and accuracy of different diagnostic methods were analyzed.Results:Among the 103 patients, 35 were benign and 68 were malignant. The SWD value of liver benign tumor group was lower than that of liver malignant tumor group [(16.38±3.58)m·s -1·kHz -1 vs (18.59±3.12)m·s -1·kHz -1], the SWD value of liver parenchyma background in liver benign tumor group was lower than that in liver malignant tumor group [(10.88±3.37)m·s -1·kHz -1 vs (14.31±3.34)m·s -1·kHz -1], and the differences were statistically significant (all P<0.05). The SWD ratio of benign tumor to surrounding liver parenchyma was higher than that of malignant tumor group [1.57(1.25, 2.00) vs 1.27(1.06, 1.57)], and the difference was statistically significant ( P<0.05). When the SWD value >15.60 m·s -1·kHz -1 was used as the cut-off value, the area under ROC curve (AUC) was 0.72, the sensitivity was 88.2%, the specificity was 51.4%, and the accuracy was 75.7%. The sensitivity, specificity, accuracy and AUC were 58.8%, 74.2%, 63.1%, and 0.68, respectively, when the ratio of SWD value<1.32 was used as the cut-off value. SWD value combined with SWD ratio for the diagnosis of liver malignant tumor, the AUC was 0.88, the sensitivity was 82.3%, the specificity was 83.0%, and accuracy was 81.6%. The diagnostic efficacy of the two in combination for liver malignant tumor was superior to SWD value ( Z=2.678, P=0.007 4) and SWD value ratio ( Z=3.822, P=0.000 1). Conclusions:SWD imaging can reflect the viscosity information of liver tumors and surrounding liver parenchyma, and has potential clinical application value in the differentiation of benign and malignant tumors.

Objective To obtain the medical exposure frequency data of residents through a questionnaire survey on mobile phone networks in the community, and to analyze the main influencing factors. Methods A snowball sampling method was used to expand the sampling from medical staff in a county hospital to the community. The questionnaire included personal information such as occupation category, type of medical insurance, and education level as well as basic radiation-related knowledge and medical exposure type and frequency of respondents received in 2021. A logistic regression model was used to analyze the influencing factors of medical exposure. Results A total of 223 respondents were investigated, and 12.56% of them received radiological diagnosis and radiotherapy in 2021. The proportion of males receiving medical exposure was significantly higher than that of females (19.64% vs 10.18%). The likelihood of the person receiving medical exposure increased considerably with age, with the proportion of residents receiving medical exposure at 20, 30, 40, and 50 years of age being 6.25%, 7.95%, 19.23%, and 33.33%, respectively. Of persons who received medical exposure, 57.14% underwent CT scans. Persons participating in the new rural cooperative medical system were likely less to receive radiological diagnosis and radiotherapy than urban workers and residents (OR = 0.55, CI:0.13-2.23, P > 0.05). Conclusion Questionnaire survey in the community can obtain more information about the medical exposure of residents, and age and type of medical insurance are important factors affecting the frequency of medical exposure.
