Case 1 A 68-year-old male patient presented with poor appetite persisting for over 2 months and had been diagnosed with liver cancer 7 days prior. He was admitted to Liaocheng Second People′s Hospital on October 17, 2017. On October 18, 2017, at 8:00, the patient underwent transcatheter arterial chemoembolization under local anesthesia. At 17:30, the patient developed a fever. At 20:00, "port wine-colored" urine was noted during catheterization, prompting transfer to the intensive care unit (ICU) for enhanced treatment. Case 2 A 67-year-old male patient with a previous diagnosis of hilar cholangiocarcinoma presented to the Emergency Department of Liaocheng Second People′s Hospital at 17:40 on March 25, 2025, due to "unconsciousness for one hour". Routine blood testing revealed significantly decreased white blood cells, red blood cells, and platelets. Considering the critical condition, the patient was transferred to the ICU. At 19:30, "port wine-colored" urine was observed in the urinary catheter. Both cases showed evident signs of hemolysis in blood samples, rapid disease progression, with fatal outcomes occurring within a short period. Blood cultures from both patients signaled positive in anaerobic bottles. Identification using the bioMérieux VITEK 2 COMPACT ANC card confirmed Clostridium perfringens. Bloodstream infections caused by Clostridium perfringens leading to such severe intravascular hemolysis are rare. The disease course is notoriously aggressive. In clinical practice, early recognition of this infection is paramount.

Objective:To analyze the metabolism of blood glucose and lipid in breast cancer patients after the first chemotherapy.Methods:Breast cancer patients who received chemotherapy for the first time from December 2016 to January 2020 were collected in our hospital, and their blood glucose and lipid levels were monitored. Patients were grouped according to different treatment plans. Non-parametric rank sum test was used for statistical analysis on SPSS software.Results:There were 1 356 female breast cancer patients were enrolled, blood glucose and lipid levels were compared before and after chemotherapy. Our results showed that baseline medium blood glucose was 5.2 mmol/L, lower than 5.3 mmol/L after chemotherapy ( P<0.05). The baseline triglyceride (TG) was 1.2 mmol/L, lower than 1.6 mmol/L after chemotherapy ( P<0.05). The baseline small dense low-density lipoprotein (sdLDL) was 0.7 mmol/L, lower than 0.8 mmol/L after chemotherapy ( P<0.05). The baseline high density lipoprotein (HDL) was 1.3 mmol/L, higher than 1.2 mmol/L after chemotherapy ( P<0.05). Patients′ menstrual status and body mass index were related with blood glucose, TG, LDL and sdLDL (all P< 0.05). Conclusions:Abnormal metabolism of blood glucose and lipid are observed in breast cancer patients after the first chemotherapy. More awareness of cardiovascular disease in breast cancer patients might ensure their overall clinical benefits.
