Objective:To explore the potential categories of symptom characteristics of early breast cancer patients undergoing postoperative chemotherapy, analyze the differences of symptoms among different categories of patients, and compare their quality of life according to different categories.Methods:This was a cross-sectional study. From January to June 2023, 240 patients with early breast cancer who received chemotherapy after surgery in General Hospital of Ningxia Medical University were selected by convenience sampling. They were investigated by general information questionnaire, Memory Symptom Assessment Scale, and Functional Assessment of Caner Therapy-Breast Cancer. Mplus 8.3 was used to carry out potential profile analysis and identify the potential categories of symptom characteristics of early breast cancer patients undergoing postoperative chemotherapy. Binary Logistic regression analysis was used to determine the influencing factors of symptom characteristics. SPSS 26.0 software was used to compare the differences in quality of life scores of patients undergoing postoperative chemotherapy for different categories of early breast cancer.Results:Totally 233 valid questionnaires were ultimately collected, with an age of 50.85 ± 8.09. There were two potential categories of postoperative chemotherapy patients with early breast cancer: low symptom troubled group (159 cases, 68.2%) and high symptom troubled group (74 cases, 31.8%). The quality of life score of the high symptom distress group was (76.84 ± 13.15) points, which was significantly lower than (89.56 ± 11.29) points of the low symptom distress group, and the difference was statistically significant ( t=7.18, P<0.01). Logistic regression analysis showed that patients with early breast cancer who had financial burden after postoperative chemotherapy were more likely to belong to the group with high symptoms [ OR (95% CI) was 3.028 (1.434-6.394), P<0.01]. Postoperative chemotherapy patients with early breast cancer who had satisfactory sleep at night are more likely to belong to the group with low symptoms [ OR(95% CI) was 0.446 (0.217-0.920), P<0.05]. Conclusions:There is population heterogeneity in the symptom characteristics of patients with early breast cancer undergoing postoperative chemotherapy. and economic burden and night sleep are the influencing factors of symptom distress categories of breast cancer patients. It is suggested that medical staff should give individualized and targeted intervention measures centered on patients′ needs according to different types of population characteristics, so as to reduce the symptom burden and improve their quality of life.

Objective:To evaluate the clinical rehabilitation effect of external counterpulsation(ECP)on patients with coronary heart disease(CHD)by meta-analysis.Methods:We searched the databases of CNKI,WanFang,VIP,CBM,PubMed,Web of Science,Cochrane Library and Embase for randomized controlled trials(RCTs)and prospective cohort studies upon rehabilitative effect of ECP on CHD patients before May 2024.And meta-analysis was conducted to calculate the pooled MD and 95％CI using the random(P＜0.5 or I2≥50％)or fixed effect models(other situations).Results:13 eligible literatures were finally included in the meta-analysis.Compared with participants in control group,those in trial group had significant higher left ventricular ejection fraction(MD=4.15,95％CI 2.55～5.76,P＜0.001),stroke volume(MD=9.11,95％CI 7.59～10.64,P＜0.001),peak oxygen uptake(MD=5.42,95％CI 2.53～8.32,P＜0.001),6-min walking distance(MD=31.14,95％CI 24.89～37.40,P＜0.001),metabolic equiv-alent(MD=0.58,95％CI 0.45～0.71,P＜0.001),exercise duration time(SMD=0.77,95％CI 0.55～0.99,P＜0.001),oxygen pulse(MD=0.88,95％CI 0.68～1.09,P＜0.001),and significant lower left ventricular end-diastolic diameter(MD=-3.19,95％CI-5.20～-2.61,P＜0.001).Conclusion:This study showed that ECP could effectively improve heart function,exercise capacity and tolerance of CHD patients.

Objective To explore the clinical efficacy and medical costs of high ligation and stripping of the great saphenous vein,simple foam sclerotherapy,and high ligation of the great saphenous vein combined with foam sclerotherapy for treating varicose of great saphenous vein.Methods The clinical data of patients with varicose of great saphenous vein undergoing high ligation and stripping of the great saphenous vein,simple foam sclerotherapy,or high ligation of the great saphenous vein combined with foam sclerotherapy were analyzed retrospectively.The evaluation included efficacy assessment,quality of life evaluation,hospitalization days and costs,postoperative complications,and recurrence after surgery.Results There were no statistical differences in gender,age,disease course and clinical etiology anatomy pathophysiology(CEAP)grading system among the three groups(P＞0.05).The clinical efficacy assessments in all patients among the three groups showed significant effects at 3 and 6 months postoperatively.One patient in the group treated with high ligation of the great saphenous vein combined with foam sclerotherapy suffered deep vein thrombosis of lower extremity after operation.In terms of quality of life,there was no statistically significant difference in venous clinical severity score(VCSS)among the three groups at 3 months postoperatively(P＞0.05).The group treated with simple foam sclerotherapy showed significantly shorter hospitalization days compared with the other two groups.Additionally,the group treated with simple foam sclerotherapy showed lower hospitalization expenses,which was not statistically significant when compared to the group treated with high ligation and stripping of the great saphenous vein group(P＞0.05),but there was a statistical difference compared to the group treated with high ligation of the great saphenous vein combined with foam sclerotherapy(P＜0.05).Conclusion There are no significant differences in clinical efficacy,postoperative pain,and quality of life evaluation among the three methods.However,simple foam scle-rotherapy may reduce the length of hospitalization stay and direct medical costs.

Objective:To develop an artificial intelligence (AI)-based platelet review strategy to identify abnormal platelet histograms with no significant difference between initial impedance platelet count (PLT-I) and PLT-F results.Methods:This study included 5 119 routine blood analysis in Nanfang Hospital of Southern Medical University and its Ganzhou branch from July 2023 and March 2024. Specimens exhibiting abnormal platelet histograms and an initial platelet count >40×10?/L underwent review using the fluorescent platelet count (PLT-F) channel. Consistency of the results was defined as a difference between impedance platelet count (PLT-I) and PLT-F less than ±20% of the PLT-F results. A deep learning model was developed using platelet and red blood cell histogram data from a training set of 3 807 specimens. The model′s diagnostic performance was evaluated on an independent external validation set ( n=805) using receiver operating characteristic (ROC) curve analysis. Changes in the number of reviewed samples and sample turnaround time were analyzed to assess its clinical utility. Results:The deep learning model based on platelet and red blood cell histograms achieved an area under the ROC curve (AUC) of 0.854 in the training set. At a cutoff value of 0.1, the sensitivity was 0.954 and specificity was 0.358. The model could reduce review by 16.80% (190/1 131). In the validation set, the AUC was 0.805, with a sensitivity of 0.955 and specificity of 0.307, corresponding to a reduction of 17.41% (47/270) in reviewed specimens.Conclusion:The platelet review prediction model developed based on deep learning technology can efficiently identify samples with consistent results before and after review, reducing unnecessary reviews and shortening specimen testing time, thereby improving the efficiency of platelet test.

Objective:To analyze the surveillance results of brucellosis in Shanxi Province, to gain a understanding of the epidemic characteristics and changing trend of brucellosis in Shanxi Province, and to provide scientific basis for formulating prevention and control strategies and measures for brucellosis.Methods:The surveillance data of brucellosis in Shanxi Province from Infectious Disease Reporting Information Management System of China Disease Prevention and Control Information System, and the active surveillance results of 5 national brucellosis surveillance sites from 2018 to 2023 were collected for descriptive analysis.Results:From 2018 to 2023, a total of 24 041 cases of human brucellosis were reported in Shanxi Province, with the number of cases increased from 2 800 in 2018 to 5 131 in 2023. The annual reported incidence was 11.22/100 000, ranging from 7.56/100 000 to 14.74/100 000, showing an overall upward trend (χ 2trend = 1 377.43, P < 0.001). The epidemic had affected all counties (cities and districts) in the province, mainly concentrated in Linfen City, Jinzhong City, Datong City, and Shuozhou City, with a total of 13 489 cases of human brucellosis reported, accounting for 56.11%. The population distribution was mainly composed of individuals aged 40 - 69 (17 682 cases), males (18 513 cases), farmers (20 295 cases), and household and unemployed individuals (1 017 cases). The onset of the disease showed obvious seasonality, with the peak time from March to August, accounting for 66.39% (15 961/24 041). A total of 14 130 occupational individuals were investigated at the surveillance sites, and 11 141 underwent serological tests, with a positive rate of 5.25% (585/11 141), including 299 new cases. The positive rate of serological tests was relatively high in Qinyuan County, at 8.51% (241/2 832). Etiological culture was conducted on 338 human blood samples, and 43 strains of Brucella were isolated, with a detection rate of 12.72%. All strains were Brucella melitensis, including 42 strains of Brucella melitensis biovar 3. Conclusions:The overall trend of human brucellosis epidemic in Shanxi Province from 2018 to 2023 is on the rise, and it is still at a high level. It is suggested to continue strengthening monitoring, study the epidemic situation in a timely manner, take comprehensive prevention and control measures, and effectively control the spread of brucellosis.

This paper summarizes the progress of theoretical research and practice of One Health in China,and discusses the paradigm of One Health governance to improve the prevention and control of infectious diseases in China and the world,and provide an example for the improvement of the public health system.In particular,China has long history to apply the concept of One Health in the national schistosomiasis control programmes and patriotic health campaigns,which were not only focusing on human health,but also emphasizing the sustainable development of animal health and ecological environment.At the same time,the application of tools such as system dynamics model,eDNA technology,One Health economic assessment and global One Health index(GOHI)in the field of disease control and environmental health provides technical support for the concept of One Health.Despite the challenges of practical application of these tools,the One Health concept will play a greater role in providing sustainable solutions for human-animal-environmental health by strengthening interdisciplinary collaboration,improving standardization protocols and promoting inter-national cooperation.

Aim To investigate the effects of tran-scription factor FoxO1 on acute kidney injury(AKI)induced by ischemic reperfusion injury(IRI)and to explore the underlying mechanisms.Methods Male C57BL/6 mice were randomly divided into four groups:Sham,IRI,FoxO1 inducible cell-specific knockout(FoxO1 icKO),and IRI+FoxO1 icKO.Tamoxifen(25 mg·kg-1)was intraperitoneally injec-ted to specifically knock out FoxO1 in mouse macro-phages,and a unilateral renal IRI model was estab-lished.The levels of serum creatinine(Scr),blood u-rea nitrogen(BUN),Fe2+,malondialdehyde(MDA),reactive oxygen species(ROS),and reduced glutathi-one(GSH)in renal tissues were detected.Hematoxy-lin-eosin(HE)staining was used to observe the patho-logical changes in renal tissues.Quantitative polymer-ase chain reaction(qPCR)was used to detect the mR-NA levels of inflammatory factors such as IL-1β and MCP1 in renal tissues.Western blot was used to detect the expression levels of apoptosis and ferroptosis-relat-ed proteins.Results Compared with the control group,the levels of Scr and BUN in the IRI group were significantly upregulated,the infiltration of inflammato-ry factors IL-1β,TNF-α and MCP1 increased,the pro-tein expressions of Bax/Bc12,cleaved-caspase-3/caspase-3,cytochrome C,and FTH1 in renal tissues were significantly enhanced,while the expression of GPX4 decreased.In addition,the levels of Fe2+,MDA and ROS in the renal cortex of the IRI group signifi-cantly increased,and the level of GSH markedly de-creased(P＜0.05).Compared with the IRI group,the levels of Scr and BUN in the FoxO1 icKO group were significantly reduced,the infiltration of inflammatory factors was alleviated,the expression of apoptosis-relat-ed proteins in renal tissue decreased,the expression level of ferroptosis protein GPX4 increased,and the ex-pression of FTH1 decreased.The levels of Fe2+,MDA and ROS in the renal cortex decreased,and the level of GSH significantly increased(P＜0.05).Conclusion Inducing the specific knockout of FoxO1 in macro-phages can alleviate AKI induced by IRI,and its mech-anism may be related to the inhibition of ferroptosis caused by IRI by FoxO1.

Objective To explore the time-varying pattern of potential symptoms in breast cancer patient before and after chemotherapy,and further analyze its influencing factors,aims to provide reference for clinical nursing practice.Methods 233 cases of breast cancer in a tertiary A hospital in Ningxia from June to October,2023 were selected as the research subjects.By the general information questionnaire and the Chinese version of Anderson Symptom Assessment Scale,the potential change of symptoms of breast cancer patients undergoing chemotherapy 1-3 days before the first chemotherapy(T1,233 cases)and 7-14 days after the third or fourth chemotherapy(T2,225 cases)was analyzed.Results 225 cases of breast cancer patients completed 2 surveys,and their symptom characteristics before and after chemotherapy can be divided into 2 categories:a high symptom troubled group and a low symptom troubled group.The high-symptom troubled group has strong stability,and the probability of maintaining the original group is 85.20％,while the low-symptom troubled group is more inclined to change to the high-symptom troubled group,and the transition probability is 26.60％.Logistic regression analysis showed that the mass was located on the left side,and the patients who obtained disease knowledge mainly through the Internet were more likely to change from the high symptom troubled group to the low symptom troubled group,while the patients who were employed,with unsatisfactory sleep at night,and never exercised were more likely to change from the low symptom troubled group to the high symptom troubled group.Conclusion The symptoms of breast cancer patients before and after chemotherapy are heterogeneous.Patients who are on the job,have unsatisfied sleep at night and never exercise are more likely to change from the low-symptom troubled group to the high-symptom troubled group,which suggests that medical staff should identify potential high-risk groups at an early stage,and make full use of the predictive function of symptom characteristics to carry out individualized management based on the dynamic monitoring of symptoms according to different types of population characteristics,so as to reduce the burden of symptoms and improve their quality of life.
