Objective:To investigate the value of community acquired respiratory distress syndrome (CARDS) toxin combined with IFN-γ in the early prediction of refractory Mycoplasma pneumoniae pneumonia (RMPP). Methods:A total of 100 children diagnosed with Mycoplasma pneumoniae pneumonia (MPP) were selected as the study objects. Among them, 36 cases were diagnosed with RMPP and 64 cases without RMPP were set as control group. The general data, clinical symptoms, signs, laboratory tests and internal and external pulmonary complications were compared between the two groups. The independent risk factors for RMPP was analyzed by Binary Logistic regression, and receiver operating characteristic (ROC) curve was used to analyze the predictive value of the indicators. Results:The fever time and hospital stay in RMPP group were significantly longer than those in control group, the relative expression of CARDS toxin, neutrophil ratio, C-reactive protein, D-dimer, lactate dehydrogenase, IL-6 and IFN-γ levels in RMPP group were higher than those in control group, and the differences were statistically significant. Binary Logistic regression analysis showed that long fever duration, increased expression of IFN-γ and CARDS toxin and extrapulmonary complications were independent risk factors for RMPP. ROC curves were drawn for the three continuous variables of fever time, IFN-γ, and relative expression of CARDS toxin, the sensitivity and specificity of the combined prediction of the three indexes were 86.1% and 73.4%, respectively.Conclusions:CARDS toxin is closely related to MPP. Fever duration, IFN-γ, relative expression of CARDS toxin and extrapulmonary complications are independent risk factors for RMPP. Especially when the fever time is more than 10.5 d, IFN-γ is more than 31.79 pg/ml, and the relative expression of CARDS toxin is more than 1.18, the possibility of RMPP should be noted.

AIM: To study the effect of intense pulsed light(IPL)combined with meibomian gland massage on postoperative dry eye in cataract patients with meibomian gland dysfunction(MGD).METHODS: A retrospective analysis was conducted on the general data of 100 patients(100 eyes)with cataract and postoperative dry eye syndrome accompanied by MGD treated in our hospital from June 2022 to June 2023. They were divided into a control group(n=50)and an observation group(n=50)according to different treatment methods, and received meibomian gland massage and meibomian gland massage combined with IPL treatment, respectively. The tear film break-up time(BUT), Schirmer I test(S I t), meibomian gland secretion score, ocular surface disease index(OSDI), ocular staining score(OSS), and treatment efficacy of the two groups of patients were compared before treatment and at 1 wk and 1 and 3 mo after treatment.RESULTS: The BUT and SIt in both groups after treatment were higher than those before treatment, while the secretion of meibomian gland, OSS score, and OSDI score were lower than those before treatment(all P<0.05); the observation group had higher levels of BUT and SIT at 1 wk, 1 and 3 mo compared to the control group(all P<0.05), and lower levels of meibomian gland secretion, OSS score, and OSDI score compared to the control group(all P<0.05); the effective rate of treatment in the observation group was 86.0%, which was higher than that in the control group(68.0%; P<0.05).CONCLUSION: IPL combined with meibomian gland massage for treating postoperative dry eye in cataract patients with MGD can promote the extension of BUT, increase tear secretion, and reduce OSS and OSDI scores.

Objective To investigate the dietary patterns of rural residents in the high-incidence areas of esophageal cancer (EC), and to explore the clustering and influencing factors of risk factors associated with high-incidence characteristics. Methods A special structured questionnaire was applied to conduct a face-to-face survey on the dietary patterns of rural residents in Yanting county of Sichuan Province from July to August 2021. Univariate and multivariate logistic regression models were used to analyze the influencing factors of risk factor clustering for EC. Results There were 838 valid questionnaires in this study. A total of 90.8% of rural residents used clean water such as tap water. In the past one year, the people who ate fruits and vegetables, soybean products, onions and garlic in high frequency accounted for 69.5%, 32.8% and 74.5%, respectively; the people who ate kimchi, pickled vegetables, sauerkraut, barbecue, hot food and mildew food in low frequency accounted for 59.2%, 79.6%, 68.2%, 90.3%, 80.9% and 90.3%, respectively. The clustering of risk factors for EC was found in 73.3% of residents, and the aggregation of two risk factors was the most common mode (28.2%), among which tumor history and preserved food was the main clustering pattern (4.6%). The logistic regression model revealed that the gender, age, marital status and occupation were independent influencing factors for the risk factors clustering of EC (P<0.05). Conclusion A majority of rural residents in high-incidence areas of EC in Yanting county have good eating habits, but the clustering of some risk factors is still at a high level. Gender, age, marital status, and occupation are influencing factors of the risk factors clustering of EC.

This study aimed to compare clinical features between membranous nephropathy (MN) and nonmembranous nephropathy (non-MN), to explore the clinically differential diagnosis of these two types, and to establish a diagnostic model of MN. After renal biopsy was obtained, 798 patients were divided into two groups based on their examination results: primary MN group (n = 248) and non-MN group (n = 550). Their data were statistically analyzed. Logistic regression analysis indicated that anti-PLA2R antibodies, IgG, and Cr were independently correlated with MN, and these three parameters were then used to establish the MN diagnostic model. A receiver operating characteristic (ROC) curve confirmed that our diagnostic model could distinguish between patients with and without MN, and their corresponding sensitivity, specificity, and AUC were 79.9%, 89.4%, and 0.917, respectively. The cutoff value for this combination in MN diagnosis was 0.34. The established diagnostic model that combined multiple factors shows a potential for broad clinical applications in differentiating primary MN from other kidney diseases and provides reliable evidence supporting the feasibility of noninvasive diagnosis of kidney diseases.

Breast cancer is one of the most common malignant tumors in clinic,and its pathogenesis has been extensively studied by people.miRNA play an important regulatory role in normal breast cell proliferation and apoptosis,they are widely involved in the occurrence and development of breast cancer and are attracting more and more attention as new tumor markers.The Wnt/β-catenin signaling pathways involved in breast cancer and other malignancies have long been confirmed.Recent studies have shown that a variety of important members of the Wnt/β-catenin signaling pathway can be regulated as miRNA target genes,affecting the occurrence and development of breast cancer.At the same time,Wnt/β-catenin signaling pathway changes can also cause the expression of related miRNA changes.Both miRNA and Wnt/ β-catenin signaling pathways play an important regulatory role in the pathogenesis of breast cancer,but the complex regulatory relationship between them has not been elucidated yet.Therefore,in this review,the roles of miRNA and Wnt/β-catenin signaling in breast cancer and its relationship with each other are reviewed in order to gain a deeper understanding of the complex pathogenesis of breast cancer and to explore new diagnostic molecular markers and therapeutic targets for breast cancer,provide a new idea for the diagnosis and treatment of breast cancer.

Breast cancer is the most common malignant tumor in female,and the recurrence and metastasis is the leading cause of death.Previous image evaluation of breast cancer could not detect the tumor at its early stage timely.The circulating tumor cells in the peripheral blood are like the seeds buried in the body,which cause the later recurrence and metastasis.So we can detect circulating tumor cells in peripheral blood to evaluate breast cancer progression.In present study,circulating tumor cells cau be implied more than three ways in clinical application of breast cancer.They could be used to monitor the therapeutic effect in breast cancer therapy timely,to analyze molecular classification of breast cancer and conduct clinical drug sensitivity tests.Although the value of circulating tumor cells in breast cancer has been widely recognized,many factors limited their application in clinical.Thus,we conduct this review about the current progress of circulating tumor cells in breast cancer.
