Objective To study Chinese medicine consultation strategies to achieve rapid capture of key information about patients'conditions and to advance the development of objectification in Chinese medicine consultation.Methods A symptom questioning model based on frequent pattern mining algorithm in correlation analysis was used,and a cross-merging method was used to establish a TCM symptom questioning strategy between single-system symptom questioning and multi-system integrated symptom questioning in TCM,to achieve the shortest time and highest efficiency in capturing key information about the patient's condition.Results A breakthrough from single-system questioning to five-system integrated questioning was achieved,and the process of efficiently obtaining information about the patient's condition was achieved through both single-system and five-system symptom questioning modes,and the system was able to obtain 92%of the patient's symptom information with at most 65%fewer questions than the traditional scale questioning method,greatly improving the efficiency of obtaining information about the patient's symptoms.Conclusion With the two different symptom questioning modes,the traditional TCM questioning mode of asking patients based on scales is broken,the time to obtain symptoms from patients is shortened,the questioning process is simplified,and discrepancies due to inexperience or human subjectivity are reduced,which can be used in clinical aids to diagnosis in TCM.

Objective To collect information from the traditional Chinese medicine(TCM)four diagnostic information of patients with coronary heart disease(CHD)and to observe the characteristics of their Chinese medicine syndrome factor at different ages,to provide an objective basis for the Chinese medicine treatment of patients with CHD at different ages.Methods The TCM Four Diagnostic Information Collection Scale for CHD developed by the group was used to collect the four diagnostic information of patients with coronary heart disease,and the syndrome elements were extracted according to the syndrome differentiation standard to observe the distribution of syndrome elements at different ages.Results CHD is located in the heart and accompanied by liver,kidney,stomach,lung and other organs.Qi deficiency is the most common syndrome factor,followed by phlegm turbidity,yin deficiency,blood stasis and qi stagnation.Among the syndrome elements of disease location,the heart and liver were the most common in the young group,and the heart and kidney were more common in the middle-aged group and the elderly group.Among the syndrome elements of disease nature,qi deficiency was more common in the young group,phlegm turbidity and qi stagnation were more common in the empirical group,and qi deficiency and phlegm turbidity were the most frequent.In the middle-aged group,qi deficiency was more common in deficiency syndrome,phlegm turbidity and blood stasis were more common in excess syndrome,and the frequency of qi deficiency and phlegm turbidity and blood stasis was the highest.In the elderly group,qi deficiency and yin deficiency were more common in deficiency syndrome,phlegm turbidity and blood stasis were more common in excess syndrome,and qi and yin deficiency combined with phlegm turbidity and blood stasis had the highest frequency.Conclusion The combination of syndrome elements in patients with CHD in different age groups has its own characteristics.The young,middle and elderly groups are all visible in the mixture of deficiency and excess,while the young group is the most common with qi deficiency and phlegm turbidity,the middle-aged group is the most common with qi deficiency and phlegm turbidity and blood stasis,and the elderly group is the most common with qi and yin deficiency and phlegm turbidity and blood stasis.With the increase of age,the complexity of the combination of syndrome elements is higher.

BackgroundSleep disorder can adversely affect human physical and mental health， with important implications for socioeconomic development. And higher vocational college students are subject to various pressures and stimuli exerted by academic studies， job seeking and family socioeconomic status， which may contribute to the onset insomnia symptom or sleep disorder. ObjectiveTo discuss the sleep status and influencing factors among higher vocational college students， and to provide references for improving their sleep status. MethodsIn January and February， 2022， a stratified random sampling method was utilized to enroll 3 300 students from five higher vocational colleges in Wenjiang district of Chengdu city. All the participants were assessed using Insomnia Severity Index （ISI）， Patient Health Questionnaire Depression Scale-9 item （PHQ-9） and Generalized Anxiety Disorder Scale-7 （GAD-7）. Pearson correlation analysis was conducted to test the correlation of ISI with PHQ-9 and GAD-7 scores， and the Logistic regression analysis was performed to identify the influencing factors of insomnia symptom in higher vocational college students. ResultInsomnia symptom was detected in 81.90% （2 497 / 3 300） of higher vocational college students. The detection rate of insomnia symptom among vocational college students yielded statistical difference in terms of gender， family socioeconomic status， being an only child or having siblings， degree of psychological pressure exerted by academic studies or job seeking， amount of hours spent on Internet per day， frequency of physical exercise， and the presence or absence of anxiety symptom and depression symptom （χ²=21.032， 22.172， 8.983， 75.939， 36.781， 32.350， 54.512， 86.561， P<0.01 or 0.05）. Among higher vocational college students， ISI score was positively correlated with GAD-7 and PHQ-9 scores （r=0.620， 0.714， P<0.01）， and GAD-7 score was positively correlated with PHQ-9 score （r=0.824， P<0.01）. Gender， family socioeconomic status， degree of psychological pressure exerted by academic studies or job seeking， amount of hours spent on Internet per day， frequency of physical exercise， and the presence or absence of anxiety symptom and depression symptom were effective factors in predicting the insomnia symptom in higher vocational college students （P<0.01 or 0.05）. ConclusionFemale gender， average and below average family socioeconomic status， moderate-to-severe degree of psychological pressure exerted by academic studies or job seeking， spending 2~5 h， 5~7 h or >7 h on Internet per day， inadequate physical exercise and presence of depressive symptom are the risk factors for insomnia symptom in higher vocational college students.［Funded by Sichuan Provincial Primary Health Development Research Center in 2022， North Sichuan Medical College （number， SWFZ22-C-89）］

Objective:To explore the clinical application of time of flight-magnetic resonance angiography (TOF-MRA), silent magnetic resonance angiography (SilenZ-MRA) and high-resolution vessel wall imaging (HR-VWI) in non-invasive evaluation of intracranial aneurysm after embolization.Methods:From February 2021 to February 2022, 39 patients, including 8 males and 31 females, who were 29-86 (54.50±11.80) years old and had received intracranial aneurysm embolization were collected in the Second Affiliated Hospital of Nanchang University. Kruskal-Wallis test was used to compare the image quality score and the evaluation results of lumen stenosis rate in the stent segments by TOF-MRA, SilenZ-MRA and HR-VWI. The diagnostic value of TOF-MRA, SilenZ-MRA and HR-VWI was analyzed by receiver operating characteristic (ROC) curve with DSA as the reference standard.Results:The image quality scores of TOF-MRA, SilenZ-MRA and HR-VWI were 2(1, 3), 4(3, 4) and 4(4, 4), respectively, with statistically significant difference ( H=80.78, P<0.05). The pairwise comparison results were as follows: TOF-MRA vs SilenZ-MRA, P<0.017; TOF-MRA vs HR-VWI, P<0.017; SilenZ-MRA vs HR-VWI, P>0.017. The lumen stenosis rates of stent segments measured by TOF-MRA, SilenZ-MRA, HR-VWI and DSA were 45.00% (29.60%, 61.05%), 17.60% (10.80%, 26.80%), 13.35% (8.90%, 15.95%) and 7.95% (4.80%, 11.25%), respectively, with statistically significant difference ( H=67.96, P<0.05). The results of comparison between TOF-MRA, SilenZ-MRA, HR-VWI and DSA were respectively as follows: TOF-MRA vs DSA, P<0.017; SilenZ-MRA vs DSA, P<0.017; HR-VWI vs DSA, P>0.017. DSA review showed that 12 (27.91%,12/43) aneurysms were not completely embolized, and 31 (72.09%, 31/43) aneurysms were completely embolized. The area under the curve of TOF-MRA, SilenZ-MRA and HR-VWI for evaluating the postoperative complete embolization of aneurysm was 0.75, 1.00 and 0.94, respectively, with statistically significant differences between TOF-MRA and HR-VWI ( Z=2.53, P<0.05) as well as between TOF-MRA and SilenZ-MRA ( Z=3.32, P<0.05). Conclusions:HR-VWI can clearly display the stent-segment lumen of the parent artery, and evaluate the stent-segment arterial wall and whether the stent-segment lumen is unobstructed or not. SilenZ-MRA is significantly superior to TOF-MRA in the evaluation of postoperative embolization status of aneurysms, and slightly superior to HR-VWI in tumor neck display. Combined application of HR-VWI and SilenZ-MRA has certain clinical significance for non-invasive evaluation of intracranial aneurysm after embolization.

Objective : To explore whether the NLRP3 inflammasome is activated after Newcastle disease virus (NDV) exposure to esophageal cancer ECA109 cells , whether its activation is related to K + efflux , and the effect of ATP/P2X7 axis on the activation of NLRP3 inflammasome. Methods: The expression of NLRP3 and IL⁃1β was detected by Western blot; the content of IL⁃1β in the supernatant was detected by ELISA ; the formation of ASC spots was detected by fluorescence immunoassay; the change of intracellular K + concentration was detected by fluorescent probe technology; Interventions with ATPase , ATP and P2X7 receptor inhibitors were used to investigate their role in NLRP3 inflammasome activation. Results: Compared with the control group , the expression of NLRP3 , IL⁃1β and ASC protein in cells was up⁃regulated after NDV F3 infection ; the intracellular potassium concen tration decreased with the prolongation of infection time (P < 0. 05) . After the intervention of P2X7 receptor inhibitor, the efflux of intracellular K + was blocked. With the increase of inhibitor concentration , the efflux of K + was maximally inhibited at 10 μmol/L (P < 0. 05) . The results of ATPase and ATP intervention showed that ATPase inhibited K + efflux , while ATP promoted K + efflux. Western blot results showed that compared with the control group , P2X7 receptor was inhibited , and the expressions of NLRP3 and IL⁃1β were down⁃regulated ; after ATPase intervened cells , the expressions of NLRP3 and IL⁃1β decreased ; After ATP intervention in cells , the protein expressions of NLRP3 and IL⁃1β were up⁃regulated (P < 0. 05) . Conclusion NDV F3 infection of ECA109 cells can activate the NLRP3 inflammasome , the mechanism may be related to the ATP/P2X7 axis.

Objective:To explore any effect of electroacupuncture (EA) at the Zusanli point on the scorch death of duodenal cells in rats with functional dyspepsia (FD) and possible mechanisms.Methods:Twenty-four 7-day-old Sprague-Dawley rats were randomly divided into a blank group, a model group and an EA group, each of 8. FD was induced in both the model and EA group rats using iodoacetamide gavage with tail-clip stimulation. After successful modeling the EA group was given acupuncture at the Zusanli point and then connected with a Korean acupuncture point nerve stimulator for 2 weeks. The other 2 groups were not given any intervention. The rats′ body weight was recorded before and after the modeling, as well as 7 and 14 days later. The gastric emptying rate and the small intestine propulsion rate of the three groups were detected right after the EA intervention, and the serum expression levels of interleukin-1β (IL-1β) and interleukin-6 (IL-6) were measured using enzyme-linked immunoassays. Real-time fluorescence quantitative polymerase chain reactions were used to detect the transcription levels of IL-1β and IL-6 in the rats′ duodenums, while western blotting was employed to assess the expression of caspase-1 P20 and dermatin D (GSDMD) in their duodenums.Results:After successful modeling, the average body weight of the rats in the model and EA groups was significantly different from that in blank group, and after 7 and 14 days the average body weight of the former groups was significantly different from that of the blank group, with significant differences between the two groups as well. After the EA intervention significant differences were observed in gastric reside and small intestine propulsion rate between the EA group and the model group, as well as between the model and the blank group. After the intervention, there were significant differences between the blank group and the other two groups in the average expression of IL-1β and IL-6 in serum, IL-1β and IL-6 mRNA in the duodenum, as well as the GSDMD and caspase-1 p20 proteins in the duodenum. There were significant differences between the model and EA groups in all of the above measurements.Conclusions:EA at the Zusanli point can significantly reduce the level of scorch death in the duodenum of FD rats, as well as relieve low-grade duodenal inflammation and the clinical symptoms of FD. Its mechanism may be related to the down-regulation of the expression of caspase-1 P20 and GSDMD-N protein, and of inflammatory factors such as IL-1β and IL-6, relieving low-grade duodenal inflammation.
