Objective To investigate the clinical efficacy of Xiaozhi Tea(composed of Eupatorii Herba,Nelumbinis Folium,Chrysanthemi Flos,Cassiae Semen,Crataegi Fructus,bran-fried Atractylodis Macrocephalae Rhizoma,Poria,Pseudostellariae Radix,Citri Reticulatae Pericarpium,Glycyrrhizae Radix et Rhizoma Praeparata cum Melle)combined with Atorvastatin Calcium Tablets for the treatment of hyperlipidemia patients with turbid phlegm obstruction syndrome.Methods A retrospective cohort study was conducted in 200 hyperlipidemia patients with turbid phlegm obstruction syndrome who visited the outpatient department of Shenzhen Bao'an Traditional Chinese Medicine Hospital Group from September 2023 to September 2024.The patients were equally divided into a trial group and a control group based on the treatment regimen,with 100 cases in each group.The control group received oral use of Atorvastatin Calcium Tablets alone,while the trial group received Xiaozhi Tea in addition to Atorvastatin Calcium Tablets orally,both groups were treated for 8 weeks.Changes in traditional Chinese medicine(TCM)syndrome scores and lipid profiles of total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDL-C)in the two groups were observed before and after treatment.After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)There were 3 patients in the control group dropping out due to lack of follow-up data,leaving 197 patients who eventually completed the study,100 cases in the trial group and 97 cases in the control group.(2)After 8 weeks of treatment,the total effective rate in the trial group was 97.00%(97/100)and that in the control group was 87.63%(85/97).The intergroup comparison(tested by chi-square test)showed that the trial group showed significantly stronger efficacy than the control group(P＜0.05).(3)Both groups exhibited significant reductions in TCM syndrome scores after treatment in comparison with those before treatment(P＜0.05),and a more pronounced reduction was presented in the trial group(P＜0.05).(4)Both groups showed decreased TC,TG,and LDL-C levels(P＜0.05)and increased HDL-C level after treatment in comparison with those before treatment(P＜0.05).The trial group demonstrated more obvious reduction of TC,TG,LDL-C,and more obvious elevation of HDL-C than the control group(P＜0.05).(5)In terms of safety,no severe adverse reactions occurred in either group.The incidence of adverse reactions in the trial group was 1.00%(1/100)and that in the control group was 2.06%(2/97),with no statistically significant difference between groups(P＞0.05).Conclusion Xiaozhi Tea combined with Atorvastatin Calcium Tablets exerts certain efficacy in treating hyperlipidemia with turbid phlegm obstruction syndrome,and is effective on significantly improving lipid profiles and clinical symptoms.The combination therapy demonstrates superior efficacy compared to Atorvastatin Calcium Tablets alone.

Objective To analyze the relationship between the body mass index(BMI)and anal fistula occurrence based on the results of cross-sectional survey.Methods The clinical data of 545 patients with a-nal fistula visiting in the proctology department of this hospital from March 2022 to November 2023 were ana-lyzed.The patients were divided into 4 groups based on BMI:skinny group(BMI＜18.5 kg/m2),normal group(BMI 18.5-＜24.0 kg/m2),overweight group(BMI 24.0-＜28.0 kg/m2)and obese group(BMI ≥28.0 kg/m2).The logistic regression was used to analyze the influencing factors of fistula occurrence.The dose-response relationship between BMI and the occurrence risk of anal fistula was analyzed by combining with the restricted cubic spline(RCS)model.Results The logistic regression analysis results showed that obese was the risk factor of anal fistula occurrence(OR=2.08,95％CI:1.08-3.99,P=0.028).The combining RCS a-nalysis results showed that there was a"J"shaped trend between the BMI and the risk of anal fistula.In addi-tion,smoking could increase the risk of anal fistula occurrence in obese population.Conclusion Overweight and obesity are the risk factors for anal fistula occurrence.It is suggested that the susceptible population should control their body weight reasonably to prevent the occurrence of anal fistula.

Objective:To analyze the research hotspots and trends of swallowing disorders in patients with head and neck tumors both domestically and internationally, to provide reference for future research directions.Methods:Using the China National Knowledge Infrastructure and Web of Science core collection databases as data sources, research literature related to swallowing disorders in head and neck tumor patients published from January 1, 2013, to December 31, 2022, was retrieved. A knowledge graph was drawn using Cite Space 6.2 R3 software, and the graph was interpreted and analyzed from the aspects of publication volume, publication country, and institution, high-frequency keyword co-occurrence and clustering, and emergent words.Results:A total of 427 English literature were included. The overall number of publications is on the rise. The countries with a high volume of collaborative publications were the United States, Australia, the Netherlands, and the United Kingdom. The top three institutions in terms of publication volume were the University of Queensland in Australia, the University of Newcastle in the UK, and the Amsterdam Institute in the Netherlands. A total of 10 cluster clusters and 25 prominent keywords were obtained. The hot topics of research and analysis were "swallowing dysfunction" "associated complications" and "long-term effects", with the forefront being "radiation-induced dry mouth syndrome".Conclusions:Compared to foreign countries, China currently has a relatively small number of publications, loose cooperation between research authors and institutions, and a need for more diverse disciplines and research methods. Focusing on hot topics and cutting-edge content, exploring the mechanism of swallowing disorders in head and neck tumors, implementing targeted interventions, strengthening health education, predicting postoperative dangerous complications, constructing feasible nursing plans, and improving the quality of life of patients will become the development trend of future research.

ECG signals and sleep monitoring parameters complement each other and can be used for qualitative diagnosis of sleep apnea syndrome and cardio-related diseases.However,due to the limitations of the instrument volume and the detection environment,it is often challenging to integrate these two functions in practical applications.In this paper,a 12-lead dynamic electrocardiograph integrated with sleep monitoring is designed.The system's volume is reduced by combining the integrated ECG simulation front end with a miniature sensor.The system achieves the extraction,conditioning,and calculation of 12-lead ECG signals and sleep-related parameters and writes the data to a memory card in real time,which offers convenience for users and doctors in the diagnostic process.

Objective:To explore the mediating role of disease progression′s fear and positive affect in the relationship between disease perception and demoralization in patients with chronic heart failure. It provided a theoretical basis for targeted interventions for healthcare workers.Methods:From October 2022 to March 2023, 320 patients with chronic heart failure in the First Affiliated Hospital of Zhengzhou University were selected as the research objects by convenience sampling. The General Information Questionnaire, Demoralization Scale Redacted Mandarin Version, Brief Illness Perception Questionnaire, Fear of Progression Questionnaire-Short Form, Positive and Negative Affect Schedule (Positive Affect Schedule) were used to conduct the questionnaire survey exploring the mediating effects of fear of disease progression and positive emotions between disease perception and disorientation by construction structural equation model.Results:There were 268 valid questionnaires. Of the 268 patients, 168 were male and 100 were female, 3.36% (9/268) were ≤40 years old, 55.22% (148/268) were 41-65 years old, and 41.42% (111/268) were >65 years old. Correlation analysis showed that disease perception was positively correlated with disease progression ′s fear, and every dimension of demoralization ( r values were 0.300-0.586, all P<0.01), and negatively correlated with positive affect ( r=-0.374, P<0.01); disease progression′s fear was negatively correlated with positive affect ( r=-0.318, P<0.01), and positively correlated with every dimension of demoralization ( r values were 0.339-0.464, all P<0.01); positive affect was negatively correlated with every dimension of demoralization ( r values were -0.430--0.334, all P<0.01). Structural equation model analysis showed that the direct effect of disease perception on demoralization was significant ( β=0.407, P<0.01), and both mediating effects of disease progression ′s fear and positive affect between disease perception and demoralization in patients with chronic heart failure were significant ( β=0.074, 0.079, both P<0.01). The chain mediating effect of disease progression ′s fear and positive effect was also significant ( β=0.019, P<0.01). Conclusions:Disease perception could directly predict the demoralization of patients with chronic heart failure and indirectly predict the demoralization of patients with chronic heart failure through the mediating effect of disease progression ′s fear, positive affect, and the chain mediating effect of disease progression ′s fear and positive affect.

Fetal ECG monitoring is a routine clinical detection method that can reflect the changes of fetal heart in utero in real time. At present, most of the clinical fetal heart rate detection adopts the ultrasonic Doppler method, which is technically difficult and highly specialized in operation and expensive. This study introduces a fetal ECG detection system based on the maternal abdominal electrode method. The weak fetal ECG changes are sensed through the maternal abdominal electrode, and the mixed ECG signal is obtained through the corresponding amplification and filtering circuit. Finally, the obtained signal is passed through WiFi, transmitted to the host computer. The host computer uses the adaptive filtering algorithm to estimate the fetal ECG signal. The system has strong feasibility, low operation expertise, low cost, and is more convenient.

Body temperature is an important physiological parameter of the human body and is used in medicine to reflect the physiological state and health status of the human body. At present, the commonly used clinical thermometers on the market are mainly divided into contact and non-contact types.
