ObjectiveWe conducted a drug resistance and homology analysis of diarrheagenic Escherichia coli (DEC) in Fengxian District of Shanghai in order to provide a basis for clinical rational drug use, risk monitoring and early warning. MethodsDEC were isolated from diarrheal patients in Fengxian District, Shanghai from 2019 to 2022. The minimum inhibitory concentrations (MIC) of 21 drugs to the DEC were determined. Genotyping and homology analysis were conducted with pulsed-field gel electrophoresis (PFGE). ResultsThe DEC detection rate of diarrhea cases was 18.99% (131/690), including enteroaggregative E.coli (EAEC) 64.89% (85/131), enterotoxigenic E.coli (ETEC) 22.14% (29/131), enteropathogenic E.coli (EPEC) 12.21% (16/131), and enterohemorrhagic E.coli (EHEC) 0.76%(1/131). The DEC detection showed obvious seasonal characteristics with a high incidence in summer. The DEC multidrug resistance rate was 66.41% with a total of 65 drug resistance profiles. The five antimicrobial drugs with the highest resistance rate were ampicillin (60.31%), nalidixic acid (51.91%), cefazolin (50.38%), tetracycline (44.27%), and cotrimoxazole (35.11%). The rate of DEC resistance to levofloxacin was significantly increased from 2019 to 2022. Cluster analysis showed that the similarity of 85 EAEC cluster was 58.4%‒100.0%, and 69 band patterns were obtained. The similarity of 29 ETEC cluster was 58.5%‒100.0%, and 13 band patterns were obtained, including 2 dominant band types. The similarity of 16 EAEC clusters was 53.9%‒100.0%, and 15 band patterns were obtained. Five groups of homologous strains were found, consistent with the resistance phenotypes. ConclusionAmong the diarrhea cases, the DEC epidemic intensity is high, the drug resistance situation is severe, and the risk of outbreak infection is high in Fengxian District, Shanghai. Therefore, health monitoring and prevention need to be strengthened.

Gastric cancer is one of the common tumors in the world and a major cause of cancer death.Although the 5-year survival rate of gastric cancer patients has increased greatly with the improvement levels of diagnosis and treatment,the high malnutri-tion rate of gastric cancer patients still has a significant impact on their overall survival and quality of life.Malnutrition is considered an independent prognostic factor for cancer patients,early detection of malnutrition in gastric cancer patients and more reasonable peri-operative nutritional support play an important role in the survival and prognosis of gastric cancer patients.This article combines exist-ing research at domestic and abroad to review the nutritional risk screening and assessment of gastric cancer patients during periopera-tive period,as well as the research progress of perioperative nutritional support and immunonutrition,in order to provide more compre-hensive nutritional management strategies for patients with gastric cancer during the perioperative period.

OBJECTIVE:
To investigate the expression of CD47 molecules in patients with newly diagnosis of adult acute myeloid leukemia (AML) and its correlation with clinical prognosis.
METHODS:
20 patients with acute myeloid leukemia diagnosed in Shanghai Fengxian District Central hospital from April 2020 to October 2021 and 5 cases with non malignant hematological diseases in the control group were collected, and the expression of CD47 in single nuclear cells of bone marrow and peripheral blood was detected by real-time fluorescence quantitative polymerase chain reaction (qPCR). Combined with the blood image, bone marrow smears, flow cytometry, chromosome and gene detection, ECOG score, etc. during the patient's initial diagnosis, the relationship between the patient's prognosis and CD47 was evaluated.
RESULTS:
The expression of CD47 in bone marrow (P=0.0115) and peripheral blood mononuclear cells (P=0.0069) in new diagnosis AML patients was significantly higher than that of controls. In bone marrow mononuclear cells, the total survival time of patients with high CD47 expression was less than that of CD47 low expression patients (P=0.036). There was statistical significance in difference stratification group (P=0.012), but there was no statistical significance between CD47 expression and survival time in peripheral blood mononuclear cells (P=0.116). There were no statistical significance between bone marrow mononuclear cell CD47 expression and gene mutation fusion genes related to leukemia , CD34+, CD38+, CD123+ (P>0.05). The proportion of bone marrow protocells in AML patients was >50%, the ECOG score was >2 points, MLLELL fusion gene and chromosome prognosis stratification were all risk factors affecting the survival of patients (P=0023, 0.036, 0.012, 0.001, respectively). The high expression of bone marrow CD47 in AML patients indicated a high risk of recurrence (P=0.017).
CONCLUSION
The high expression of bone marrow mononuclear cell CD47 in AML patients indicates poorer survival and higher risk of recurrence.

MEK is a canonical effector of mutant KRAS; however, MEK inhibitors fail to yield satisfactory clinical outcomes in KRAS-mutant cancers. Here, we identified mitochondrial oxidative phosphorylation (OXPHOS) induction as a profound metabolic alteration to confer KRAS-mutant non-small cell lung cancer (NSCLC) resistance to the clinical MEK inhibitor trametinib. Metabolic flux analysis demonstrated that pyruvate metabolism and fatty acid oxidation were markedly enhanced and coordinately powered the OXPHOS system in resistant cells after trametinib treatment, satisfying their energy demand and protecting them from apoptosis. As molecular events in this process, the pyruvate dehydrogenase complex (PDHc) and carnitine palmitoyl transferase IA (CPTIA), two rate-limiting enzymes that control the metabolic flux of pyruvate and palmitic acid to mitochondrial respiration were activated through phosphorylation and transcriptional regulation. Importantly, the co-administration of trametinib and IACS-010759, a clinical mitochondrial complex I inhibitor that blocks OXPHOS, significantly impeded tumor growth and prolonged mouse survival. Overall, our findings reveal that MEK inhibitor therapy creates a metabolic vulnerability in the mitochondria and further develop an effective combinatorial strategy to circumvent MEK inhibitors resistance in KRAS-driven NSCLC.
