Objective To investigate the vaccination status and vaccination willingness of novel coronavirus in HIV/AIDS population in Yunnan.Methods From October 2021 to June 2022,a questionnaire survey was conducted among 2180 HIV/AIDS patients in Kunming,Qujing,Yuxi,Zhaotong,Puer,Baoshan,Lincang,Honghe,Wenshan,Xishuangbanna,Dali,Dehong and Nujiang prefectures.The questionnaire included age,sex,education,nationality,education level,vaccination,adverse reactions within 7 days after the vaccination,safety of COVID-19 vaccine,awareness of effectiveness,vaccination willingness and so on.Results Among the subjects,2109 completed 3 injections,accounting for 96.74%,and 71 were not vaccinated,accounting for 3.26% .Within 7 days of inoculation,local adverse reactions occurred in 116 cases,accounting for 5.50%,and systemic adverse reactions occurred in 56 cases,accounting for 2.66% .Injection site pain,fatigue and muscle pain accounted for the highest proportion of adverse symptoms in different sex,age and the Han nationality,while the proportion of minority adverse reactions was very low,and there was no difference among the different sex and age(P>0.05).The main reasons for the reluctance of HIV/AIDS population to be vaccinated were(recommended by doctors)that HIV/AIDS patients could not be vaccinated(67.61%)and may have serious adverse reactions after the vaccination(19.72%).The factors affecting the vaccination were found by logistic regression analysis,whether they were worried about infecting novel coronavirus(OR = 0.121,95% CI = 0.083～0.640,P<0.001)and how much they knew about COVID-19 vaccine(OR = 28.932,95% CI = 15.469～54.115,P<0.001),safety of vaccination(OR = 13.953,95% CI = 4.819～40.404,P<0.001)and belief in the preventive effect of vaccine(OR = 14.017,95% CI = 4.752～41.348,P<0.001)were significant factors affecting vaccination.Among the 13 prefectures and cities,Dehong(20),Zhaotong(21)and Lincang(14)had the largest number of unvaccinated people.Conclusion After the mass vaccination,the rate of adverse reaction in HIV/AIDS population is low,the symptoms are mild,the correct and scientific advice and guidance from doctors and the full understanding of the harmfulness of the disease,the safety,prevention and effectiveness of the vaccine are the key to complete vaccination and put an end to vaccine hesitancy.

This study aims to construct C57/B6-L and A549 cell lines that stably overexpress circu-lar RNA LAMP3(circLAMP3),laying the foundation for further research on the biological func-tions of circLAMP3.Total RNA was extracted and reverse transcripted into cDNA from C57/B6-L and A549 cells to amplify the full-length sequence of circLAMP3.Then,the fragments of cir-cLAMP3 were ligated into pLC5-ciR vector to obtain pLC5-Mouse-circLAMP3 and pLC5-Human-circLAMP3 recombinant plasmids.The lentiviruses expressing circLAMP3 were packaged on tran-sient transfected HEK293T cells.C57/B6-L and A549 cells were infected with lentiviruses to gen-erate cell lines overexpressing circLAMP3 through puromycin screening.To verify the overexpres-sion efficiency of circLAMP3 of cell lines,we performed the fluorescence microscopy,PCR amplifi-cation,quantitative PCR(qPCR),and Sanger sequencing experiments.The results indicated that the overexpression plasmids of pLC5-Mouse-circLAMP3 and pLC5-Human-circLAMP3 were suc-cessfully constructed.Strong green fluorescence was observed under a fluorescence microscopy.C57/B6-L and A549 cell lines showed a significant increase in the expression of circLAMP3 by PCR and qPCR methods.Sanger sequencing results showed that the junction site of circLAMP3 was correct.This study successfully constructed C57/B6-L and A549 cell lines overexpressing circLAMP3,providing biomaterials for further exploration of the biological function of circLAMP3 in influenza virus replication.

Objective:To construct a classification model for endoscopic ultrasonography (EUS) images of gastrointestinal stromal tumors (GISTs) and leiomyomas (LM) based on deep learning technology, and to verify its value for differential diagnosis.Methods:From October 2014 to October 2021, 69 patients of GISTs and 73 of LM who underwent EUS and were pathologically confirmed by surgery or endoscopic resection in the Second Affiliated Hospital of Soochow University were retrospectively studied. One clear EUS image with typical lesion was selected for each case. Using the hold-out method, the images of each disease were divided into the training set and the validation set according to the ratio of the number of images in the training set to the number of images in the validation set, which was 8∶2. Finally, 113 EUS images (55 GISTs and 58 LM) were used to form the training set, and 29 EUS images (14 GISTs and 15 LM) were used to form the validation set. The training set was used to train and optimize the deep learning model, and the validation set was used to verify the classification model. The main observation indicators included the sensitivity, the specificity, the positive predictive value, the negative predictive value and the accuracy of differential diagnosis.Results:The accuracy of the classification model established by Resnet 34 network structure in the differential diagnosis of GISTs and LM tended to be 0.89, better than the classification model established by Resnet 50 network structure (0.81). The sensitivity, the specificity, the positive predictive value, the negative predictive value and the accuracy of the classification model based on Resnet 34 network structure for differentiating EUS images in the validation set were 85.71% (12/14, 95% CI: 67.38%-100.00%), 93.33% (14/15, 95% CI: 80.71%-100.00%), 92.31% (12/13, 95% CI: 77.82%-100.00%), 87.50% (14/16, 95% CI: 71.30%-100.00%) and 89.66% (26/29, 95% CI: 78.57%-100.00%), respectively. Conclusion:It is feasible to use deep learning technology in the differential diagnosis of EUS images of GISTs and LM, which can provide auxiliary diagnostic opinions for clinicians. The deep learning model based on Resnet 34 network structure shows higher accuracy in the differential diagnosis of EUS images of GISTs and LM.

Objective To explore the potential categories of self-regulatory fatigue among maintenance hemodialysis patients and their relationships with self-management. Methods A total of 502 maintenance hemodialysis patients in Lanzhou were surveyed using a general information questionnaire, a Self-Regulatory Fatigue Scale, and a Self-Management Scale for Hemodialysis Patients. Potential profile analysis was conducted on self-regulatory fatigue, and its relationship with self-management was explored. Results Based on their self-regulatory fatigue status, maintenance hemodialysis patients could be categorized into four potential groups: low self-regulatory fatigue group (5.0%), moderate self-regulatory fatigue group (49.2%), high self-regulatory fatigue group (13.9%), and high cognitive regulatory fatiguegroup (31.9%). Gender, education level, and monthly per capita family income were identified as influencing factors for the potential categories of self-regulatory fatigue. Significant differences were observed in the total self-management scores among patients belonging to different potential categories of self-regulatory fatigue (F=50.617, P < 0.001). Conclusion Maintenance hemodialysis patients can be classified into four potential categories of self-regulatory fatigue, with patients in the low self-regulatory fatigue group demonstrating higher levels of self-management. Reducing the level of self-regulatory fatigue can contribute to enhancing patients'self-management capabilities.

ObjectiveIn the treatment of acute gouty arthritis （AGA）， western medicine is mostly used for anti-inflammatory and analgesic purposes to control the blood uric acid level， but some patients are still at risk of poor control and recurrent attacks. Chinese medicinal prescriptions， potent in resisting inflammation and relieving pain， are able to stabilize the blood uric acid level， reduce acute attacks， and improve the clinical efficacy of western medicine. However， there is a lack of evidence to support their use as evidence-based medicine. This study employed network Meta-analysis （NMA） to evaluate the efficacy and safety of common Chinese medicinal prescriptions in the treatment of AGA， aiming to provide evidence-based medical evidence for the clinical use of Chinese medicinal prescriptions in the treatment of AGA. MethodChinese and English databases were searched for prospective cohort studies and randomized controlled trials （RCTs） on Chinese medicinal prescriptions against AGA from database inception to December 1， 2022. Stata software and Review Manager were used for statistical analysis. ResultForty-four papers with 3 564 cases involved were included in the current NMA. In terms of reducing blood uric acid， the cumulative probability results showed that Mahuang Lianyao Chixiaodou Tang showed optimal efficacy （87.60%）. In terms of relieving joint pain， Danggui Niantongtang and Guizhi Shaoyao Zhimutang showed optimal efficacy （92.00% and 82.30%）. In terms of improving erythrocyte sedimentation rate （ESR）， Simiaowan was superior to other prescriptions （87.00%）. In terms of reducing C-reactive protein （CRP）， Simiaowan and Baihutang modified with Guizhitang showed superior efficacy （76.00% and 66.10%）. In terms of safety， except for the basic treatment group， Mahuang Lianyao Chixiaodou Tang had the lowest probability of adverse events， and Danggui Niantongtang had the highest probability of adverse reactions during treatment. According to the results of cluster analysis， Mahuang Lianyao Chixiaodou Tang and Simiaowan are effective and safe. ConclusionAccording to the results of NMA， Chinese medicinal prescriptions can assist in the treatment of AGA and improve the effectiveness of western medicine. For patients with AGA， clinicians can choose Mahuang Lianyao Chixiaodou Tang or Simiaowan as an auxiliary drug for routine western medicine treatment.

To present the clinical characteristics and the misdiagnosis rate of acute coronary syndrome manifested primarily as throat discomfort, we conducted a multicentric and retrospective study in the cardiology and otorhinolaryngology departments. Records of patients with primary complaint of throat discomfort, absence of chest pain at onset, and an ultimate diagnosis of acute coronary syndrome, as well as patients with pharyngitis (as controls) were collected from May 2015 to April 2016. The patients' main manifestations were compared. Logistic regression results showed that chest tightness, dyspnea, perspiring, and exertional throat symptoms were significantly associated with acute coronary syndrome, with odds ratios of 8.3 (95% CI 2.2-31.5), 10.9 (95% CI 1.8-66.9), 25.4 (95% CI 3.6-179.9), and 81.2 (95% CI 13.0-506.7). A total of 25 (56.82%) out of 44 acute coronary syndrome patients, who were first admitted to the otorhinolaryngology department, were misdiagnosed, with a 12% (3/25) mortality rate. Throat discomfort can be the principal manifestation of acute coronary syndrome. Such patients exhibit high misdiagnosis and mortality rates. Exertional throat symptoms, chest tightness, perspiring, and dyspnea were important indicators of acute coronary syndrome in patients whose main complaint was throat discomfort. The awareness of this condition will result in prompt diagnosis and reduce morbidity and mortality.

Objective: To investigate the effects of parental feeding practices on anemia in children aged 0-6 years in the minority area of the plateau, and to provide evidence for anemia intervention. Methods: A total of 1 726 children aged 0-6 years in 4 counties of Gannan Tibetan Autonomous Prefecture were selected by stratified random cluster sampling to measure hemoglobin level. Parental feeding practices were evaluated. Results: The anemia prevalence rate among children aged 0-6 years was 50.3%. The prevalence of anemia was higher in those with younger age, Tibetan ethnic, rural residence, low parents education level and family income(χ2=156.95，899.51，148.17，8.18，16.36，11.03，P<0.05). Parentl awareness rates on feeding knowledge were 10.0%-53.7%. The report rates of distraction and force-feeding were 51.4% and 36.1%, respectively. Logistic regression analysis showed that parents incorrect feeding knowledge and compulsive feeding behaviors were positively associated with anemia in children(P<0.05). Conclusion Improvement of parents health literacy and feeding behavior is an important intervention to reduce anemia in children aged 0-6 years.

Objective: To analyze the role of school based symptom monitoring system in public health emergencies in Hangzhou, to provide the basis for prevention and control strategies for public health emergencies in schools. Methods: Data regarding school public health emergencies in Hangzhou in 2019 were collected from the Public Health Emergencies Report Management Information System, and data regarding public health early warning in schools were collected from the Hangzhou School Symptom Monitoring System. The usage of school symptom monitoring system was analyzed by SAS 9.0 software, and the positive warning events and public health emergencies were compared and analyzed, the rate and composition ratio were compared with the χ 2 test, the number of cases was compared with the non parameter rank and the Mann Whitney test, and the trend test was conducted using Cochran Armitage test. Results: In 2019, the average use rate of the city s school symptom monitoring system was 54.65%, the average response rate of automatic early warning was 70.68%, and the use rate (χ 2=860.79, p<0.01) and automatic early warning response rate (χ 2=1 615.91，P<0.01) of school systems varied greatly by region. In 2019, 161 positive early warning incidents were detected through the school symptom monitoring system, 197 public health emergencies were reported through the emergency network, and fewer public health emergencies were reported in areas where more positive warning events were detected(Z=10.65，P<0.01). The proportion of disease category in positive warning events was different from that in public health emergencies in(χ 2=28.33, P<0.01). The number of cases of positive early warning events of the same disease was much lower than the number of cases of public health emergencies without warning, and the time of positive warning signals was on average 4 days ahead of the time of receiving the report of public health emergencies. Conclusion Smartphone based school symptom monitoring system in Hangzhou plays a sentinel role in public health emergencies prevention and control in schools.
