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.

Gastric cancer(GC)is one of the most common and high mortality tumors in the world,and the clinical staging during diagnosis is closely related to the prognosis of patients.Therefore,finding sensitive diagnostic biomarkers to improve the early diagnosis rate has become an urgent issue.Exosomes are nanoscale extracellular vesicles secreted by various cells,which play an important role in cellular communication by transporting bioactive substances in tumor microenvironment(TME).CircRNA is a type of non-coding RNA with a specific structure.Because it is difficulty in degradation,it can be enriched in extracellular vesicles and participate in various pathophysiological processes mediated by it.Exo-circRNA can affect the proliferation,invasion,drug resistance and tissue metastasis of tumor cells,and has more significant diagnostic specificity than conventional diagnostic biomarkers in clinical practice.It may become a supplement to biomarker for the diagnosis and prognosis of GC.This article briefly introduces the characteristics,formation mechanism and role of extracellular vesicles and circRNA in GC.It discusses in detail the role of exo-circRNA in the occurrence and development of GC,and discusses their potential clinical application value and challenges in GC.

Conclusions:Streptococcus parasuis could cause human infection and be identified by whole-genome sequencing.

Objective:To investigate the value of multi-stage dynamic contrast enhanced MRI (DCE-MRI) histogram in predicting survival of patients undergoing surgical treatment of colorectal cancer (CRC).Methods:The retrospective cohort study was conducted. The clinico-pathological data of 81 patients with CRC who were admitted to the Jiuquan City People′s Hospital from January 2018 to February 2019 were collected. There were 47 males and 34 females, aged (62±6)years. All patients underwent routine MRI and DCE-MRI examination to extract relevant imaging parameters. Observation indicators: (1) treatment, imaging examination and follow-up; (2) imaging factors influencing postoperative disease-free survival of patients with CRC. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Univariate and multivariate analyses were conducted using the COX proportional risk model. Pearson correlation test was used to analyze and exclude factors with correlation in univariate analysis, and the multi-variate analysis was conducted on the rest of factors. The Kaplan-Meier method was used to calculate survival rates, and Log-Rank test was used for survival analysis. Results:(1) Treatment, imaging examination and follow-up. All 81 patients underwent preoperative MRI plain scan, enhanced imaging, and diffusion weighted imaging. After complete examination, all patients underwent radical resection of CRC and received postoperative chemotherapy using the FOLFOX regimen. All 81 patients were followed up for 42(range, 11-61)months after surgery. The 1-, 3-, 5-year overall survival rate of 81 patients after surgery was 98.8%, 96.3%, 93.8%, respectively. During the follow-up period, 56 of the 81 patients survived from disease-free and 25 patients had disease progressed. (2) Imaging factors influencing postoperative disease-free survival of patients with CRC. Results of multivariate analysis showed that the kurtosis value and skewness value of positive enhancement integral (PEI) were independent imaging factors influencing postoperative disease-free survival of patients of CRC ( odds ratio=1.840, 1.243, 95% confidence interval as 1.403-2.412, 1.020-1.516, P<0.05). Taking the median values of kurtosis value and skewness value of PEI as 4.864 and 5.042 for further analysis. The postoperative 5-year disease-free survival rate of patients with kurtosis value of PEI <4.864 and ≥4.864 was 89.7% and 10.3%, showing a significant difference between them ( χ2=31.265, P<0.05). The postoperative 5-year disease-free survival rate of patients with skewness value of PEI<5.042 and ≥5.042 was 63.4% and 36.6%, showing a significant difference between them ( χ2=8.164, P<0.05). Conclusions:The kurtosis value and skewness value of PEI in DCE-MRI are independent imaging factors influencing postoperative disease-free survival of patients of CRC. The DCE-MRI histogram can effectively evaluate the postoperative prognosis of patients of CRC.

Breast cancer has become the most commonly diagnosed cancer type in the world. A combination of chemotherapy and photothermal therapy (PTT) has emerged as a promising strategy for breast cancer therapy. However, the intricacy of precise delivery and the ability to initiate drug release in specific tumor sites remains a challenging puzzle. Therefore, to ensure that the therapeutic agents are synchronously delivered to the tumor site for their synergistic effect, a multifunctional nanoparticle system (PCRHNs) is developed, which is grafted onto the prussian blue nanoparticles (PB NPs) by reduction-responsive camptothecin (CPT) prodrug copolymer, and then modified with tumor-targeting peptide cyclo(Asp-d-Phe-Lys-Arg-Gly) (cRGD) and hyaluronic acid (HA). PCRHNs exhibited nano-sized structure with good monodispersity, high load efficiency of CPT, triggered CPT release in response to reduction environment, and excellent photothermal conversion under laser irradiation. Furthermore, PCRHNs can act as a photoacoustic imaging contrast agent-guided PTT. In vivo studies indicate that PCRHNs exhibited excellent biocompatibility, prolonged blood circulation, enhanced tumor accumulation, allow tumor-specific chemo-photothermal therapy to achieve synergistic antitumor effects with reduced systemic toxicity. Moreover, hyperthermia-induced upregulation of heat shock protein 70 in the tumor cells could be inhibited by CPT. Collectively, PCRHNs may be a promising therapeutic way for breast cancer therapy.
