Objective:To analyze the anatomical characteristics and surgical management measures of acute Stanford type A aortic dissection (AAD) involving coronary arteries, and to preliminarily explore the clinical efficacy of different coronary artery treatment techniques.Methods:A retrospective analysis was conducted on the clinical data of 42 patients who underwent surgery for AAD involving coronary arteries in Hunan Provincial People′s Hospital from January 2022 to May 2025. They were divided into the MI group (14 cases) and the nMI group (28 cases) according to whether they had acute myocardial infarction before surgery. The clinical data such as the actual surgical methods and mortality in the two groups were summarized.Results:Among 294 surgeries, 42 cases (14.3%) had definite coronary artery involvement, including 14 cases in the MI group and 28 cases in the nMI group; 1 case had bilateral coronary artery involvement and 41 cases had right coronary artery involvement. Regarding injury types: 16 cases were of the coronary trunk compression type, 12 cases were of the sinus intimal tear neal to ostium type, and 14 cases were of the coronary trunk intimal type. There was no statistically significant difference in the types of coronary artery involvement between the two groups ( P>0.05). There were 18 cases of Sun′s procedure with preserved aortic sinus and aortic valve, 7 cases of Bentall procedure without bypass, and 17 cases of Bentall procedure plus bypass. There was no statistically significant difference in the surgical plans between the two groups ( P>0.05). There were 4 deaths within 30 days (2 cases in each group). Conclusions:AAD involving coronary arteries is a critical condition, and accurate diagnosis is somewhat difficult. Myocardial ischemia is not significantly associated with the type of coronary artery involvement. The surgical plan depends on the type of coronary artery involvement. The classification method in this study is conducive to selecting appropriate surgical methods and improving surgical prognosis.

Objective To observe the effectiveness and safety of the"Stomach Three Needles"in preventing acute chemotherapy-induced nausea and vomiting(CINV)in patients with breast cancer.Methods Seventy patients with breast cancer who received highly emetogenic chemotherapy(HEC)and were admitted to the Third People's Hospital Affiliated to Fujian University of Traditional Chinese Medicine from January 2023 to May 2025 were selected as research subjects.They were divided into treatment group(35 cases)and control group(35 cases)according to the random number table method.The treatment group received"Stomach Three Needles"combined with triple-drug prophylactic antiemetic therapy,while the patients in control group were given triple-drug prophylactic antiemetic therapy alone.The severity of nausea and vomiting symptoms during the acute phase,functional living index-emesis(FLIE),and adverse reactions between two groups of patients were compared.Results The severity grades of acute-phase nausea and vomiting symptoms in treatment group were all lower than those in control group(P＜0.05).The complete response rate and total effective rate of acute-phase nausea and vomiting in treatment group were significantly higher than those in control group(P＜0.05).The FLIE score of the patients in treatment group was significantly higher than that in control group(P＜0.05).There was no statistically significant difference in the occurrence of adverse reactions such as headache,fatigue,constipation,and abdominal distension between two groups of patients(P＞0.05).Conclusion The"Stomach Three Needles"combined with triple-drug prophylactic antiemetic therapy can effectively reduce the incidence and severity of acute CINV in breast cancer patients,improve their quality of life,and has good safety.It is worthy of clinical promotion.

Objective To compare the long-term survival of elderly patients with esophageal squamous cell carcinoma (ESCC) treated with surgical versus non-surgical treatment. Methods A retrospective analysis was conducted on the clinical data of elderly patients aged ≥70 years with ESCC who underwent esophagectomy or radiotherapy/chemotherapy at Sichuan Cancer Hospital from January 2009 to September 2017. Patients were divided into a surgical group (S group) and a non-surgical group (NS group) according to the treatment method. The propensity score matching method was used to match the two groups of patients at a ratio of 1∶1, and the survival of the two groups before and after matching was analyzed. Results A total of 726 elderly patients with ESCC were included, including 552 males and 174 females, with 651 patients aged ≥70-80 years and 75 patients aged ≥80-90 years. There were 515 patients in the S group and 211 patients in the NS group. The median follow-up time was 60.8 months, and the median overall survival of the S group was 41.9 months [95%CI (35.2, 48.5)], while that of the NS group was only 24.0 months [95%CI (19.8, 28.3)]. The 1-, 3-, and 5-year overall survival rates of the S group were 84%, 54%, and 40%, respectively, while those of the NS group were 72%, 40%, and 30%, respectively [HR=0.689, 95%CI (0.559, 0.849), P<0.001]. After matching, 138 patients were included in each group, and there was no statistical difference in the overall survival between the two groups [HR=0.871, 95%CI (0.649, 1.167), P=0.352]. Conclusion Compared with conservative treatment, there is no significant difference in the long-term survival of elderly patients aged ≥70 years who undergo esophagectomy for ESCC. Neoadjuvant therapy combined with surgery is still an important choice to potentially improve the survival of elderly patients with ESCC.

BACKGROUND: Doxorubicin hydrochloride (DOX) is extensively used in the treatment of various tumors. However, its clinical application is limited due to dose-dependent cardiotoxicity. Currently, few effective strategies exist to mitigate or eliminate DOX-induced cardiomyopathy (DIC). Although ferroptosis is implicated in DIC and its inhibition partially alleviates the condition, the direct targets of DOX in the progression of cardiotoxicity remain unclear. This study aimed to discover the direct targets of DOX in ferroptosis-mediated DIC. METHODS: A DOX pulldown assay was performed to identify proteins specifically binding to DOX in murine hearts, followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) to identify candidate proteins. A cardiac injury mouse model was established by DOX treatment. Based on this, multiple ferroptosis biomarkers were detected by flow cytometry, quantitative real-time polymerase chain reaction, western blotting, immunochemistry, etc. Besides, specific activator and inhibitor of signaling pathways were applied to illuminate molecular mechanisms. RESULTS: Glutathione S-transferase P1 (GSTP1) was identified as a DOX target. GSTP1 activity was inhibited in DOX-treated cardiomyocytes, while its overexpression significantly alleviated DIC. Moreover, GSTP1 overexpression inhibited acyl-CoA synthetase long-chain family member 4 (ACSL4)-dependent ferroptosis. Mechanistically, GSTP1 overexpression suppressed c-Jun N-terminal kinase (JNK) phosphorylation, thereby reducing reactive oxygen species (ROS) production and inhibiting ferroptosis in DIC. CONCLUSIONS This study identifies the DOX/GSTP1/JNK axis as a critical pathway mediating ACSL4-dependent ferroptosis in DIC. GSTP1 is highlighted as a potential key mediator of ferroptosis and a promising therapeutic target for DIC.

Objective:To analyze the characteristics of non-seroconverted cases after rabies vaccination and observe the effect of booster vaccination.Methods:A retrospective collection of data was conducted from March 2022 to March 2023 across 409 rabies vaccination clinics in 27 provinces in China, focusing on cases with rabies virus neutralizing antibody (RVNA) levels less than 0.5 IU/ml after vaccination.Results:A total of 77 cases were identified in whom seroconversion was not observed within 30 days post-vaccination with the rabies vaccine. The gender distribution was 51.9% male and 48.1% female, with ages ranging from 2 to 83 years old. Delayed vaccination was observed in 11 cases (14.3%), and 63 cases (81.8%) received human rabies immunoglobulin (HRIG) injections. None of the cases had a confirmed immunosuppressive disease or taking immunosuppressive drugs, and the body mass index (BMI) distribution ranged from 14.37 to 34.74 kg/m 2. Seventy-six cases seroconverted after 1 to 3 doses of rabies vaccines as a booster vaccination. One case that did not seroconvert after the initial booster vaccination seroconverted after receiving additional 2 doses of vaccine. All patients were followed up for one year, with no cases of rabies reported. Conclusions:The characteristics of cases that failed to seroconvert after the full course of rabies vaccination lacked specificity, and booster vaccination could lead to seroconversion.

Non-neonatal tetanus is an acute, specific, toxic disease in patients over 28 days of age, characterized by continuous rigidity and paroxysmal spasms of the skeletal muscles throughout the body caused by the intrusion of Clostridium tetani through skin or mucosal membrane into the body and reproducing in anaerobic environments to produce exotoxins. The mortality rate of severe patients is close to 100% without medical intervention. Even with aggressive comprehensive treatment, the global mortality rate remains at 30%-50%, making it a potentially fatal disease. In order to standardize the diagnosis, treatment and prevention of non-neonatal tetanus, based on "Regulation for Diagnosis and Treatment of Non-neonatal Tetanus (2019 Edition)", experts have revised this regulation according to clinical practice and recent research progress in this field to guide medical institutions in the prevention and control of non-neonatal tetanus. This article interprets the key points and basis for updating the 2024 edition regulation to guide clinical implementation and application.

Objective:To analyze the epidemiological characteristics of rabies in China from 2007 to 2023, and to provide reference evidence for tailoring strategies to facilitate the elimination of rabies in the country.Methods:Case data from 2007 to 2023 were obtained from China′s National Notifiable Infectious Disease Reporting Information System, and the spatial, temporal, and demographic features of cases were analyzed.Results:From 2007 to 2023, a total of 18 751 human rabies cases were reported in China, with an average annual incidence rate of 0.08 per 100 000. The average annual percentage change (AAPC) in incidence rate was -18.58% (95% CI: -21.32% to -15.75%, P<0.05), with three significant turning points in 2011, 2018, and 2021. Based on the trend of the epidemic, Chinese provinces can be roughly divided into five categories. The geographical range affected by rabies has decreased from 23 provinces and 984 counties (districts) in 2007 to 17 provinces and 101 counties (districts) in 2023. Since 2019, the high-incidence counties (districts) have been mainly concentrated in the southwestern part of Hunan, the southern part of Henan, and the western part of Anhui. Fourteen provinces have reported no cases for at least two consecutive years. Males (70.24%) and farmers (72.18%) were the main affected groups, and the proportion of cases aged 65 and above increased from 17.43% in 2007 to 36.07% in 2023. Conclusions:The incidence of rabies in China has changed from endemic in many areas to sporadic, with the remaining endemic regions mainly located in parts of the middle and lower reaches of the Yangtze River. The main vulnerable groups are middle-aged and elderly farmers. The current prevention and control measures can effectively curb the transmission of rabies, but the decline of cases has slowed down recently.
