Objective To explore the clinical effect of Fu's subcutaneous needling combined with western medicine in the treatment of irritable bowel syndrome(IBS).Methods A total of 112 patients with IBS were randomly divided into the observation group and the control group,with 56 patients in each group.The control group was given conventional western medicine treatment,and the observation group was treated with Chinese medicine Fu's subcutaneous needling on the basis of the treatment in the control group.Both groups were treated for 4 consecutive weeks.After 1 month of treatment,the clinical efficacy of the two groups was evaluated,and the changes in the IBS system severity system(IBS-SSS)scores were observed before and after the treatment,as well as the time of the symptoms of abdominal pain,bloating and diarrhoea subsiding in the two groups,and the changes in the defecation thresholds,pain thresholds,sensory thresholds and the changes in the numbers of intestinal flora such as Bifidobacterium,Lactobacillus,Enterobacteriaceae,and Bacteriodendrobacteriaceae in the two groups were compared.The changes in the levels of vasoactive intestinal peptide,gastric motility and substance P were observed in the two groups.The safety and occurrence of adverse reactions were also evaluated in the two groups.Results(1)The total effective rate of the observation group was 96.43%(54/56),and the control group was 83.93%(47/56).The efficacy of the observation group was superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)The time for abdominal pain,abdominal distension and diarrhoea to subside was significantly shorter in the observation group than in the control group,and the difference was statistically significant when compared with the control group(P＜0.05).(3)After treatment,the defecation threshold,pain threshold,and sensation threshold of patients in the two groups were significantly improved(P＜0.05),and the observation group was significantly superior to the control group in terms of improving defecation threshold,pain threshold,and sensation threshold,and the difference was statistically significant(P＜0.05).(4)After treatment,the numbers of Bifidobacterium,Lactobacillus,Enterobacter,Bacteroides were significantly improved in the two groups(P＜0.05),and the observation group was significantly superior to the control group in terms of improving the numbers of Bifidobacterium,Lactobacillus,Enterobacter and Bacteroides,and the difference was statistically significant(P＜0.05).(5)After treatment,the levels of vasoactive intestinal peptide,gastric actin,and substance P of the patients in the two groups were significantly improved(P＜0.05),and the observation group was significantly superior to the control group in improving the levels of vasoactive intestinal peptide,gastric actin,and substance P,and the differences were all statistically significant(P＜0.05).(6)There was no significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion Fu's subcutaneous needling combined with western medicine in the treatment of IBS can significantly shorten the relief time of patients'clinical symptoms,strengthen patients'gastrointestinal function,regulate the number of intestinal flora and improve the function of gastrointestinal mucous membrane barrier,and the therapeutic efficacy is remarkable.

Objective To analyze the characteristics of adult anomalous aortic origin of coronary artery(AAOCA)and the causes of missed diagnosis by transthoracic echocardiography(TTE)so as to facilitate TTE in diagnosing adult AAOCA.Methods A total of 37 adult patients with AAOCA diagnosed by non-invasive coronary CT angiography(CCTA)and/or invasive coronary angiography(ICA)were selected as research samples at some hospital from January 2019 to December 2022,and their clinical symptoms and the findings of 12-lead electrocardiogram,cardiac enzymes and TTE were summarized;the patients were typed according to the site of origin of coronary artery anomalies,and the causes for the missed diagnosis of TTE were eplored.Chi-square test was used to compare the differences in TTE missed diagnoses.Results Of the 37 patients,31 ones had no or only mild symptoms;most ones had negative results in terms of 12-lead electrocardiography,cardiac enzymes,changes in the size of the cardiac chambers,segmental ventricular wall motion abnormalities and left ventricular systolic function.The patients with anomalous origin of the right coronary artery from left sinus(ARCA-L)gained the largest proportion of 59.45％(22/37);21 patients were diagnosed with anomalous origin of coronary artery arising from the opposite sinus(ACAOS)in the two examinations of TTE,of whom there were 19 cases of ARCA-L,and the detection rate of ACAOS by TTE was 87.5％;all the 13 patients origins in branches and high-grade openings were missed by TTE.The detection rate of ACAOS by TTE was significantly higher than that of coronary artery anomalies originating in branches and in high openings,and the difference was statistically significant(21/24 vs 0/13,P＜0.001).Conclusion Most adult AAOCA patients lack specificity in symptoms and related examination results.TTE has a high detection rate of ACAOS,while it is easy to miss the diagnosis of coronary artery anomalies originating from branches and high openings.Ultrasonographers have to identify false negative AAOCA by multi-section and multi-angle scanning and color Doppler flow imaging in order to reduce the rate of missed diagnosis.[Chinese Medical Equipment Journal,2024,45(1):71-75]

ObjectiveThe scale of microalgae farming industry is huge. During farming, it is easy for microalgae to be affected by miscellaneous bacteria and other contaminants. Because of that, periodic test is necessary to ensure the growth of microalgae. Present microscopy imaging and spectral analysis methods have higher requirements for experiment personnel, equipment and sites, for which it is unable to achieve real-time portable detection. For the purpose of real-time portable microalgae detection, a real-time microalgae detection system of low detection requirement and fast detection speed is needed. MethodsThis study has developed a microalgae detection system based on deep learning. A microscopy imaging device based on bright field was constructed. With imaged captured from the device, a neural network based on YOLOv3 was trained and deployed on microcomputer, thus realizing real-time portable microalgae detection. This study has also improved the feature extraction network by introducing cross-region residual connection and attention mechanism and replacing optimizer with Adam optimizer using multistage and multimethod strategy. ResultsWith cross-region residual connection, the mAP value reached 0.92. Compared with manual result, the detection error was 2.47%. ConclusionThe system could achieve real-time portable microalgae detection and provide relatively accurate detection result, so it can be applied to periodic test in microalgae farming.
