Here reports a rare case of severe pneumonia with pulmonary abscess and empyema caused by Trophe-ryma whipplei(TW)infection.TW infection was confirmed by clinical manifestations as well as polymerase chain reaction(PCR)of bronchoalveolar lavage fluid(BALF)and pleural effusion.After treatment with meropenem(fo-llowed by sequential ceftriaxone)combined with compound sulfamethoxazole,the patient improved and was dis-charged from hospital.Combined with literature review,this study explores the clinical manifestations,laboratory examinations,and treatment scheme of TW infection,aiming to improve the awareness and vigilance of clinicians on TW infection,conduct targeted anti-infection therapy as early as possible,and reduce the mortality of patients.

Metabolic bariatric surgery is an effective intervention for obesity and related metabolic disorders.Beyond substantial weight reduction,it modulates orexigenic and anorexigenic neuropeptides and their signaling pathways to improve energy homeostasis and metabolic function.This review summarizes the regulatory effects of various bariatric procedures(such as Roux-en-Y gastric bypass and sleeve gastrectomy)on orexigenic neuropeptides and anorexigenic factors,highlighting the involvement of key signaling pathways including mTOR and AMPK.These mechanisms contribute to weight control,enhanced insulin sensitivity,and remission of metabolic diseases.By integrating central and peripheral regulatory processes,metabolic surgery provides new biological insights into individualized obesity management.Future research should focus on interindividual variability and long-term neuro-metabolic adaptations to optimize surgical outcomes and improve metabolic health.

Tumors exhibit abnormal glucose metabolism, consuming excessive glucose and excreting lactate, which constructs a tumor microenvironment that facilitates cancer progression and disrupts immunotherapeutic efficacy. Currently, tumor glucose metabolic dysregulation to reshape the immunosuppressive microenvironment and enhance immunotherapy efficacy is emerging as an innovative therapeutic strategy. However, glucose metabolism modulators lack specificity and still face significant challenges in overcoming tumor delivery barriers, microenvironmental complexity, and metabolic heterogeneity, resulting in poor clinical benefit. Nanomedicines, with their ability to selectively target tumors or immune cells, respond to the tumor microenvironment, co-deliver multiple drugs, and facilitate combinatorial therapies, hold significant promise for enhancing immunotherapy through tumor glucose metabolic reprogramming. This review explores the complex interactions between tumor glucose metabolism-specifically metabolite transport, glycolysis processes, and lactate-and the immune microenvironment. We summarize how nanomedicine-mediated reprogramming of tumor glucose metabolism can enhance immunotherapy efficacy and outline the prospects and challenges in this field.

Objective:To investigate the related factors of kidney injury in patients with masked hypertension (MHT).Methods:This study was a cross-sectional study. A total of 311 MHT patients who visited Dongguan Liaobu Community Health Service from June 1,2022 to June 1, 2023 were enrolled in the study. The complete blood biochemistry, urinary microalbumin and 24-hour urinary protein tests were conducted, and the risk factors of renal injury in MHT patients were analyzed with multivariate logistic regression.Results:The age of the 311 enrolled patients was(48.8±9.2)years, with 192 males(61.7%) There were 73 cases with microalbuminuria (MAU), accounting for 23.47% (73/311); and 28 cases of positive 24-hour urine total protein (24-hour UTP), accounted for 9.00% (28/311). Multivariate logistic regression analysis showed that fasting blood glucose level and mean nocturnal systolic blood pressure were independent risk factors of positive MAU in MHT patients ( OR=1.577, 95% CI: 1.049-2.370, P=0.030; OR=1.024, 95% CI: 1.001-1.047, P=0.038), while older age was a protective factor of MAU ( OR=0.965, 95% CI: 0.935-0.997, P=0.030); mean nocturnal systolic pressure, 24-hour mean systolic pressure and mean diurnal systolic pressure were independent risk factors of positive 24-hour UTP in MHT patients ( OR=1.031,95% CI: 1.000-1.064, P=0.049; OR=1.048,95% CI: 1.008-1.091, P=0.020; OR=1.042,95% CI: 1.003-1.083, P=0.035). Conclusion:Older age, fasting blood glucose, mean nocturnal systolic pressure, 24-hour mean systolic pressure and mean diurnal systolic pressure are associated with the renal injury in MHT patients.
