OBJECTIVE To provide references for the accurate identification and management of immune-related cutaneous adverse events （irCAEs） caused by durvalumab， and ensuring safe clinical drug use. METHODS Clinical pharmacists participated in the diagnosis and treatment process of a patient with gallbladder cancer who developed irCAEs caused by durvalumab. The clinical pharmacists systematically reviewed the patient’s past medical history and medication history， and assisted physicians in assessing the association between adverse drug reactions and administered drugs. Meanwhile， the clinical pharmacists conducted a graded assessment of the adverse reaction， proposed recommendations such as discontinuing durvalumab and adjusting the administration regimen of glucocorticoids， assisted physicians in restarting immunotherapy， and carried out medication education and other pharmaceutical care. RESULTS The occurrence of irCAEs in this patient was “highly likely” related to durvalumab and was classified as severe. The physicians adopted the clinical pharmacist’s opinion， and after symptomatic treatment， the patient’s skin symptoms improved， and discharged with medication. After the completion of glucocorticoid therapy for the patient， the physician restarted immunotherapy with tislelizumab， and no related adverse reactions occurred again in the patient. CONCLUSIONS Durvalumab can cause irCAEs such as severe skin maculopapular rash. In clinical practice， it is crucial to promptly identify and discontinue suspicious drugs， immediately implement effective symptomatic treatment measures， and actively resume immunotherapy to ensure the continuity and safety of the patient’s treatment.

Objective In order to understand the current resistance status of Aedes albopictus(Ae. albopictus) adult population to commonly used insecticides and the resistance dynamics development in Zhejiang Province and provide a theoretical basis for the scientific and rational use of hygienic insecticides. Methods Resistance determination was carried out using the diagnostic dose method(GB/T 26347-2010)recommended by WHO in the adult mosquito contact cylinder method to monitor the resistance of Ae. albopictus field populations in 11 cities and districts in Zhejiang Province in 2024. Results The monitoring result showed that adult Ae. albopictus in 11 areas were resistant or suspected resistant populations to both cis-cypermethrin and permethrin; suspected and resistant populations to the organophosphate insecticide malathion were as high as 81.82%; while suspected resistance to the carbamate insecticide residual carbofuran accounted for 45.45%, and the rest of the monitoring sites were sensitive to it. Conclusions The result suggest that the generalized resistance of Ae. albopictus populations to pyrethroids and organophosphorus insecticides in the field in Zhejiang Province needs to be highly emphasized. In future mosquito vector and mosquito-borne disease control, insecticides should be selected based on the resistance monitoring information, while following scientific guidelines for insecticide use.

This paper summarized professor ZHANG Boli's experience in syndrome differentiation and treatment of metabolic syndrome （MetS） based on the theory of "diseases related to damp， turbidity， phlegm， and rheum". It is considered that damp， turbidity， phlegm， and rheum are the key pathological factors in the onset of MetS. The core pathogenesis of this disease includes the failure of the liver to govern the free flow of qi， the depletion of spleen and kidney， and the accumulation and impairment caused by damp， turbidity， phlegm， and rheum. It is important to emphasize early intervention， sequential treatment， and thorough elimination of pathogenic factors. The treatment takes fortifying the spleen and promoting middle jiao （焦）， soothing the liver and regulating qi， and tonifying the kidney to restore transformation as the fundamental principles. Furthermore， targeted treatments are implemented according to the evolution of damp， turbidity， phlegm， and rheum， including treating damp early， examining the tongue coating to eliminate turbidity， differentiating and treating concurrent phlegm， and applying warm dredging moderately. At the same time， specific medicinals are combined based on abnormal indicators such as blood glucose， blood lipids， blood pressure， and uric acid， aiming to address both root causes and symptoms simultaneously.

Objective To investigate the association between dietary patterns and adolescent development in girls in Pudong New Area，Shanghai. Methods Using a stratified cluster sampling method, a total of 998 girls were selected from the cohort of growth, development, and health of children and adolescents in Pudong New Area of Shanghai. Physical development examinations and dietary surveys were conducted on these girls. Principal component analysis was used to determine girls' dietary patterns, and their relationship with adolescent development was analyzed using logistic regression. Results Among the 998 participants, 770 (77.15%) were pubertal girls. The factor analysis identified three dietary patterns, fungi and algae~nuts~legumes pattern, meat-vegetables and fruits-cereals pattern, and milk-eggs pattern. Logistic regression analysis revealed that after adjusting for age, waist circumference, residential district, mother's education level, and father's education level, the Q2 level (OR=0.54, 95% CI: 0.30-0.99), Q3 level (OR=0.50, 95% CI: 0.27-0.91), and Q4 level (OR=0.49, 95% CI: 0.26-0.90) of the fungi and algae-nuts-legumes pattern were negatively correlated with adolescent development. The Q2 level (OR=0.48, 95% CI: 0.27-0.87) and Q3 level (OR=0.49, 95% CI: 0.27-0.88) of the milk-eggs pattern were also negatively correlated with adolescent development. Conclusion The fungi and algae~nuts~legumes pattern and milk-eggs patterns are inversely related to pubertal development.

Objective To investigate the effects of hypoxia on the transcriptional phenotype and ultrastructure of tumor-associated macrophages(TAMs)in glioma.Methods CD14+monocytes were isolated from healthy human peripheral blood samples collected from the Blood Bank of the First Affiliated Hospital of Army Medical University,and the cells were induced to differentiate into TAMs through co-culture with glioma cell-conditioned medium.Hypoxic TAM models were established using varying concentrations of cobalt chloride hexahydrate(CoCl2,50～400 μmol/L)or hypoxic conditions(1%,5%,10%O2)for 48 h,while normoxic TAM models(21%O2)served as controls.RT-qPCR and transcriptome sequencing were employed to analyze transcriptional changes in TAMs under normoxic and hypoxic conditions.Gene set enrichment analysis(GSEA)was applied to compare the differences in angiogenesis,glycolysis and other hypoxia-responsive pathways between the 2 conditions.Transmission electron microscopy(TEM)or immunofluorescence staining was conducted to assess the ultrastructural alterations in cytoskeleton,endoplasmic reticulum(ER),and mitochondria in normoxic and hypoxic TAMs(1%O2).Results Hypoxic TAMs exhibited up-regulated transcription of hypoxia-responsive markers(oxygen transport,glycolysis,pro-angiogenesis),with the effects correlating with hypoxia severity(P<0.05).GSEA revealed significant up-regulation of hypoxia,angiogenesis regulation,glycolysis and gluconeogenesis,and starvation stress pathways,alongside down-regulation of innate immunity,macrophage activation,cytoskeleton,and protein maturation pathways in hypoxic TAMs(P<0.05).TEM and immunofluorescence staining demonstrated obvious ultrastructure changes,including disrupted cytoskeletal organization,shortened rough ER with reduced ribosomes,mitochondrial swelling with cristae damage,and diminished ER-mitochondria contacts in hypoxic TAMs.Conclusion CoCl2 and hypoxia induce a hypoxic transcriptional phenotype in TAMs,which may potentially associated with ultrastructural remodeling of the cytoskeleton,ER,and mitochondria.

Objective To develop a nurse-led dynamic monitoring protocol for fluid responsiveness and to evaluate its effectiveness in preventing fluid accumulation syndrome in patients with septic shock.Methods A nurse-led dynamic monitoring protocol for fluid responsiveness was developed through literature review and expert panel discussion.Using convenience sampling,160 patients with septic shock admitted to the emergency department of a tertiary hospital in Hangzhou,Zhejiang Province,were enrolled.According to admission period,80 patients admitted from November 2023 to August 2024 were assigned to an intervention group,and 80 patients admitted from January 2023 to October 2023 were assigned to a control group.The intervention group received the nurse-led dynamic monitoring in addition to routine care,while the control group received routine care and conventional fluid responsiveness monitoring.The therapeutic outcomes and incidence of complications were compared between the 2 groups.Results All 80 patients in each group completed the study.The intervention group demonstrated higher lactate clearance rates at 6 and 24 hours after fluid resuscitation,lower incidences of acute pulmonary edema and fluid accumulation syndrome,and shortened durations of mechanical ventilation and ICU stay(all P＜0.05)compared to the control group.There was no statistically significant difference in 28-day mortality between the 2 groups(P=0.212).Conclusion The nurse-led dynamic monitoring protocol for fluid responsiveness in patients with septic shock is both scientific and practical.Its implementation can effectively improve lactate clearance,reduce the incidence of fluid accumulation syndrome and acute pulmonary edema,and shorten the duration of mechanical ventilation and ICU stay.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To evaluate the anti-reflux effect of digestive tract reconstruction using esophageal-tubular gastric asymmetric anastomosis after radical resection of esophageal and esophagogastric junction cancer.Methods:The main steps were as follows:(1)oblique incision of the lower esophagus;(2)curved incision of the tubular anterior gastric wall;(3)the lower end of the esophagus was anastomosed to the tubular gastric incision with a 90-degree torsion; (4)The anterior wall of the anastomosis was reinforced with a transverse-inverted suture,the posterior wall with a folded suture,and the corners of the gastric stump were buried with sutures.The anastomosis operation time,postoperative complications and postoperative hospital stay were recorded;the reconstructed structure and anti-reflux effect of the anastomosis were observed by digestive tract radiography,gastroscopy and follow-up investigation.Results:The Department of Gastrointestinal and Thoracic Surgery of Huaian First People's Hospital, affiliated to Nanjing Medical University, treated 5 patients of esophagogastric junction cancer and 20 esophageal cancer cases between August 2022 and November 2024, including 19 men and 6 women, with a mean age of (66.7±7.4) years. The mean anastomosis time was (35.4±5.9) minutes, the intraoperative blood loss was (117.6±33.4) ml and the mean postoperative hospital stay was(16.6±5.2) days, with no complications such as anastomotic leakage and bleeding. Postoperative digestive tract radiography (Trendelenburg position)showed that all the patients had no contrast reflux,gastroscopy showed no signs of reflux esophagitis and bile reflux gastritis, the anastomosis showed an inverted whiskers valve-like structure. The median follow-up time was (16.8±6.3) months, and all patients had no reflux symptoms such as acid reflux and belching,and no acid suppressive medication was needed.Conclusion:The esophageal-tubular gastric asymmetric anastomosis is a safe and effective antireflux reconstruction technique.

Background and purpose:Polo-like kinase 4(PLK4)is a cell cycle regulatory protein,which is closely related to the occurrence and development of a variety of malignant tumors.The aim of this study was to investigate the role of PLK4 in the proliferation,invasion and apoptosis of oral squamous cell carcinoma(OSCC).Methods:Gene Expression Profiling Interactive Analysis 2(GEPIA2)and the University of Alabama at Birmingham Cancer Data Analysis Portal(UALCAN)were used to analyze the expression of PLK4 in head and neck squamous cell carcinoma and surrounding normal tissues.Real-time fluorescence quantitative polymerase chain reaction(RTFQ-PCR)and Western blot were employed to evaluate the mRNA and protein expression of PLK4 in OSCC cells.We further analyzed PLK4,phosphoinositide 3-kinase(PI3K),phosphorylated phosphoinositide 3-kinase(p-PI3K),protein kinase B(AKT),phosphorylated protein kinase B(p-AKT),survivin,and cyclin D1 protein expression.The effects of PLK4 on cell proliferation,apoptosis and invasion were analyzed by cell counting kit-8(CCK-8)assay,flow cytometry and transwell assay.In addition,12 4-week-old SPF BALB/c female nude mice were divided into sh-NC group(n=6)and sh-PLK4 group(n=6)by random number table method.The sh-NC/sh-PLK4 cells were injected into the right anterior armpit of nude mice for subcutaneous tumor formation.The body weight,tumor volume and tumor weight of the two groups of nude mice were observed,and the stripped tumor tissues were analyzed by H-E staining.The animal experiments were approved by the Animal Experiment Center of Shandong Second Medical University(No:2024SDL840).Results:The results of GEPIA2 and UALCAN online databases showed that PLK4 was highly expressed in OSCC compared with normal tissues.In addition,PLK4 was highly expressed in OSCC cell lines(HN6,Cal-27,SCC-4,SCC-9,SCC-25)compared with oral mucosal epithelial cells(P＜0.05).Western blot results showed that the expression levels of PI3K/AKT signaling pathway proteins p-PI3K,p-AKT,cyclin D1 and survivin were decreased after PLK4 knockdown and increased after PLK4 overexpression in OSCC cells(P＜0.05).The cell proliferation activity and the number of transmembrane cells were positively correlated with the decrease and increase of PLK4 expression(P＜0.05),while the cell apoptotic rate was negatively correlated(P＜0.05),indicating that cell proliferation and apoptosis were both affected.In addition,compared with the sh-NC group,the tumor volume and weight of the nude mice in the sh-PLK4 group were decreased(P＜0.05),while there was no significant difference in the body weight of the nude mice between the two groups(P＞0.05).Moreover,the nuclear atypia of tumor tissues in sh-PLK4 group was lower than that in sh-NC group(P＜0.05).Conclusion:PLK4 can regulate the invasion,proliferation and apoptosis of OSCC cells,potentially through the activation of PI3K/AKT signaling pathway.
