Objective:To evaluate the effect of hyperthermia on radiation pneumonitis (RP) in elderly patients with esophageal cancer undergoing intensity-modulated radiotherapy (IMRT).Methods:Clinical data of 177 elderly esophageal cancer patients (aged ≥60 years) receiving IMRT in the First Affiliated Hospital of Soochow University and Yixing Cancer Hospital from August 1, 2017 to February 6, 2023 were retrospectively analyzed. Patients were divided into the hyperthermia and non-hyperthermia groups based on whether they received hyperthermia treatment. Patients in two groups received IMRT with 6 MV X-rays. Patients in the hyperthermia group underwent high-frequency hyperthermia within 1 h before radiation using the external thermotherapy device HG-2000Ⅲ (heating temperature: 41-43 ℃ for 40 min, twice a week). After adjusting for confounding factors between two groups using propensity score matching (PSM), the short-term effective rates between two groups were compared using Chi-square test. Univariate analysis and logistic multivariate analysis were employed to compare the incidence of RP between two groups. Results:After applying PSM, 42 pairs were successfully matched, and the baseline data and radiotherapy parameters showed no statistically significant differences between two groups (all P>0.05). The objective response rate (ORR) in the hyperthermia group was significantly higher than that in the non-hyperthermia group (83.3% vs. 64.3%, P=0.047). Univariate analysis revealed that the incidence of RP and symptomatic RP (≥ grade 2) in the hyperthermia group was significantly lower than that in the non-hyperthermia group (61.9% vs. 85.7%, P=0.013; 21.4% vs. 47.6%, P=0.012). Logistic multivariate analysis indicated that hyperthermia was an independent protective factor for symptomatic RP ( P=0.011). Conclusions:The incidence and severity of RP in elderly esophageal cancer patients receiving IMRT can be reduced by hyperthermia. Hyperthermia, as a clinically beneficial green treatment, improves efficacy and reduces toxicity for patients with esophageal cancer.

ObjectiveTo analyze the epidemic characteristics of foodborne disease outbreaks in Mengla County, Yunnan Province, so as to provide basis for formulating corresponding prevention and control measures. MethodsThe data of foodborne disease outbreaks in Mengla County, Yunnan Province from 2017 to 2021 in the national "foodborne disease outbreak monitoring system" were collected. The time, population, region, place, pathogenic factors and inducing links of the events were statistically analyzed. ResultsFrom 2017 to 2021, a total of 68 incidents were reported, including 526 cases and 5 deaths. The total incidence rate was 23.40% and the case fatality rate was 0.95%. The peak period was from May to July, with the largest number of reported events in July. The reporting areas were mainly Mengla Town (35.29%), Guanlei Town (11.76%) and Mengpeng Town (10.29%). The main place of the incident was family (76.47%). The main pathogenic factors were plant toxins (79.41%), mainly through the ingestion of wild mushrooms (68.52%), improper processing of green beans (12.96%) and aconitum (9.26%). ConclusionAccording to the epidemiological characteristics of Mengla County, we should focus on the public education of health knowledge in key areas and places, especially on the identification of wild mushrooms, to prevent accidental eating. At the same time, we should strengthen the monitoring and risk assessment of foodborne diseases, find potential risks as soon as possible, issue early warning and forecast in time, and constantly improve the clinical treatment ability of poisoned patients.

Objective:To investigate the predictive value of tumor necrosis factor receptor-associated factor 6 (TRAF6) expression in the efficacy of radiotherapy for patients with esophageal squamous cell carcinoma (ESCC).Methods:A total of 278 patients with ESCC received radical radiotherapy in Yixing Cancer Hospital of Jiangsu Province from February 2012 to March 2015 were included. The expression of TRAF6 in esophageal cancer tissue was detected by immunohistochemistry. The correlations between the expression of TRAF6 and clinicopathological features, short-term efficacy of radiotherapy and survival of ESCC patients were investigated.Results:All the patients were divided into positive expression group ( n=194) and negative expression group ( n=84). TRAF6 expression was significantly associated with TNM stage and lymph node metastasis in ESCC patients ( χ2=13.670, P<0.001; χ2=45.497, P<0.001). The total effective rate of radiotherapy in the TRAF6 positive expression group was 62.9% (122/194), which was significantly lower than that of TRAF6 negative expression group (92.9%, 78/84), and the difference was statistically significant ( χ2=26.085, P<0.001). The median survival time of TRAF positive expression group was 51 months, while that of TRAF negative expression group was not reached, and the difference of survival curve between the two groups was statistically significant ( χ2=7.952, P=0.005). Further analysis showed that higher TNM stage, lymph node metastasis and positive expression of TRAF6 increased the risk of death in ESCC patients ( HR=1.96, 95% CI: 1.39-2.76; HR=1.72, 95% CI: 1.29-2.29; HR=2.31, 95% CI: 1.57-3.39). Conclusion:Patients with TRAF6 positive expression of ESCC have low radiotherapy sensitivity. TRAF6 may be a new target for diagnosis and treatment of ESCC patients, which provides a new idea for the diagnosis, treatment and prognosis of ESCC.

OBJECTIVETo study the molecular mechanism of cyclooxygenase-2 (COX-2), one of effective ingredient of brucine, in inducing non-small cell lung cancer cell apoptosis.
METHODCOX-2 promoter, transcription factor deletion mutants and COX-2 mRNA 3'-UTR-containing report plasmids were transfected with Renillia to non-small cell lung cancer A549 cell, in order to detect the activity of report gene luciferase and minimum cis-acting element of COX-2 promoter inhibited by brucine. The influence of brucine on IkappaB phosphorylation and the nuclear translocation of p65 were detected by immunoblotting assay.
RESULTBrucine significantly suppressed LPS-induced COX-2 promoter activation, but revealed minor impact on COX-2 mRNA stability. NF-kappaB in the vicinity of COX-2 promoter-262 was an important cis-acting element of brucine for inhibiting the activity of COX-2 promoter. Brucine was found to inhibit the phosphorylation of IkappaBalpha as well as the nuclear translocation of p65.
CONCLUSIONBrucine can improve A549 cells apoptosis by inhibiting the activity of NF-kappaB and the subsequent COX-2 gene expression.
