Onco-critical care has emerged as an important subspecialty at the intersection of critical care medicine and oncology, attracting increasing attention in recent years. With continuous innovations in cancer therapies, patient survival has improved significantly; however, the incidence of associated critical complications has also increased. The reasons for cancer patients requiring intensive care unit admission are diverse and can be broadly categorized into three groups: progression of the underlying malignancy, treatment-related complications, and coexisting classical critical illnesses. Traditional critical care concepts and practices face limitations in addressing the multidimensional and heterogeneous challenges of onco-critical care. Based on the core mechanism of critical illness development—host/organ unregulated response (HOUR)—this article systematically elaborates on how this framework advances understanding and clinical practice into onco-critical care, with emphasis on its manifestations in neuroendocrine, immune-inflammatory, and coagulation-metabolic pathways. The review summarizes recent advances in clinical assessment and phenotyping systems for onco-critical illness and discusses a multidisciplinary, integrated management strategy centered on the "Disease Control, Host Response Modulation, Organ Support" triad. Finally, major challenges and future directions in this field are outlined. By integrating existing evidence and theoretical insights, this review aims to provide new perspectives and a theoretical foundation for the clinical management of onco-critical illness, thereby promoting its evolution toward precision and standardization.

Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Spinal surgical site infection (SSI), especially deep SSI after internal fixation is difficult in treatment, with long course of disease and poor prognosis. At present, there are many controversies in the diagnosis and treatment of spinal SSI, with unsatisfactory overall efficacy of its diagnosis and treatment. Besides, no diagnosis and treatment guideline based on evidence-based medicine has been in existence. To this end, the Spinal Infection Group of the Orthopedic Branch of the Chinese Medical Doctor Association and the Spinal Infection Group of the Spinal Surgery Branch of the Chinese Rehabilitation Medicine Association jointly organized relevant experts to formulate Evidence-based clinical guideline for the diagnosis and treatment of surgical site infection in spinal trauma ( version 2024) based on an evidence-based approach. A total of 10 recommendations were proposed on the diagnosis and treatment of spinal SSI, so as to provide a clinical reference for the diagnosis and treatment of spinal SSI.

ObjectiveTo assess the diagnostic efficiency of different diffusion models （DTI， DKI and NODDI） in grading glioma and predicting IDH-1 mutation status， and to further build logistic regression prediction models. MethodsTotally 66 patients （22 females； mean age： 47.8） with pathologically proved gliomas were retrospectively included. All cases underwent bipolar spin echo diffusion examination. Parameters of DKI （MK； Ka； Kr）， DTI （MD and FA） and NODDI （intracellular volume fraction： icvf， orientation dispersion index： odi） were derived. ROIs were manually drawn and corresponding average values were calculated. Logistic regression was performed to build a predictive model. ROC curve was obtained， and Hosmer-lemeshow test was carried out to test the goodness of fit. ResultsDKI， DTI and NODDI parameters were significantly different between HGGs and LGGs （P < 0.01）. And among all diffusion parameters， a further logistic regression model for grading glioma only included age and MK， which showed the highest diagnostic value ［AUC=0.88， AUC 95%CI （0.79， 0.96）］. Hosmer-lemeshow Test present excellent of goodness of fit. With IDH-1 mutation status， NODDI showed no significant value for distinction， whereas DKI and DTI can significantly differentiate IDH-1 mutated and non-mutated glioma （P < 0.05）. Further logistic regression only selected Kr （P <0.01） in the model， which demonstrated the highest diagnostic value ［AUC=0.72， AUC 95%CI （0.59， 0.85）］. ConclusionsDKI is superior to DTI and NODDI in grading gliomas and identifying IDH-1 mutation status. The model of MK value and age variables present the best discriminatory capacity for grading glioma and Kr value may serve as a potential predictive index for identify IDH-1 mutation.

According to the pathological characteristics of symptomatic chronic thoracic and lumbar osteoporotic vertebral fracture (SCOVF), the different clinical treatment methods are selected, including vertebral augmentation, anterior-posterior fixation and fusion, posterior decompression fixation and fusion, and posterior correction osteotomy. However, there is still a lack of a unified understanding on how to choose appropriate treatment method for SCOVF. In order to reflect the new treatment concept and the evidence-based medicine progress of SCOVF in a timely manner and standardize its treatment, the clinical guideline for surgical treatment of SCOVF is formulated in compliance with the principle of scientificity, practicability and advancement and based on the level of evidence-based medicine.

Objective: To analyze the genetic characteristics of a five generations pedigree with homozygous familial hypercholesterolemia (HoFH). Methods: Prospective study. Twenty family members included a proband diagnosed as familial hyperlipidemia at the cardiology Department of Xi′an Children′s Hospital in October 2018 were research object. Clinical data were collected. Genome DNAs were extracted. Whole exons sequencing was performed on the proband using target capture next generation sequencing. Candidate gene mutation sites identified by bioinformatics were verified by Sanger sequencing in the family members. The genotype-phenotype correlation of the pedigree was analyzed between heterozygous mutation carriers and non-carriers. Results: The proband was a 7-years and 10-month-old boy. He was born with a roundgreen bean size yellow skin protuberance in the skin of the coccyx. Since the age of 3-4 years old, xanthoma-like lesions with a diameter of 0.5-1.5 cm gradually appeared in the skin of bilateral elbow joints, knee joints and Achilles tendon. The height, weight and intellectual development of the child were the same as those of normal children at the same age. No similar xanthoma-like lesion was found in the other family members. The proband′s total cholesterol (TC) reached 18.16-21.24 mmol/L, and his low density lipoproteincholesterol (LDL-C) was 14.08-15.51 mmol/L. Carotid ultrasonography showed diffuse sclerotic plaques in bilateral carotid and vertebral arteries, and color Doppler echocardiography revealed aortic valve thickening and calcification. Gene testing identified that the proband carried a homozygous mutation C. 418G>A (p. E140K) in LDLR gene inherited from his parents who had a consanguineous marriage and carried a heterozygous mutation of LDLR-E140K, respectively.The TC, LDL-C and apolipoproteinB (ApoB) of LDLR-E140K gene heterozygous carriers ((8.40±0.13), (6.79±0.01) and (1.95±0.05) mmol/L, respectively) were significantly higher than those of non-carriers ((4.59±0.28), (3.35±0.39) and (0.86±0.10) mmol/L, t=7.269, 4.595, 6.311, respectively, P<0.05). Conclusions LDLR-E140K gene homozygous mutation is first reported to be associated with most severe phenotype HoFH. The genotype-phenotype analysis of the pedigree shows that the clinical phenotype of the proband with homozygous mutation is the most serious, and all the heterozygous mutation carriers present with hypercholesterolemia phenotype. The investigation confirms that LDLR-E140K is the pathogenic variation of familial hyperlipidemia.

OBJECTIVETo evaluate the value of blood lactic acid (BLA) as a predictor for the severity and prognosis of neonatal shock.

METHODSA total of 326 neonates with shock were enrolled and divided into three groups based on the severity, namely mild group (n=147), moderate group (n=105), and severe group (n=74). BLA level was measured during and early after (about 6 hours later) fluid resuscitation, and lactate clearance rate (LCR) was calculated. The receiver operating characteristic (ROC) curve was applied to evaluate the predictive value of BLA in neonatal shock.

RESULTSBLA level was high in all subjects prior to treatment, and was highest in the severe group and lowest in the mild group (P<0.01). BLA level was significantly higher among patients with septic shock than among those with hypovolemic, cardiogenic, and asphyxiating shock (P<0.05). BLA level was significantly reduced in patients in recovery after treatment (P<0.05). Mortality was significantly lower in patients with BLA level ≤4 mmol/L or LCR ≥10% than in those with BLA level >4 mmol/L or LCR <10% (P<0.01). BLA at 11.15 mmol/L had 100% sensitivity and 96.8% specificity in predicting severe shock. BLA at 10.65 mmol/L had 88.9% sensitivity and 74.1% specificity in predicting the prognosis (survival or dead) of newborns with shock.

CONCLUSIONSIn neonates with shock, arterial BLA level increases as the disease severity increases and is associated with prognosis, so it is a useful predictor of the severity and prognosis of neonatal shock.

The average recovery of phenol and L-menthol was 99. 01%(RSD=0. 90%,n=9)and 99. 70%(RSD=0. 98%,n=9), respectively. Conclusion: The method is sim-ple, accurate and reliable, and can be used to determine the concentration of phenol and L-menthol in glycerin Zhiyang lotions.

OBJECTIVETo explore the potential markers of colorectal cancer metastasis and the influence of 5-FU on differentially expressed proteins by using proteomic technology, and to elucidate the mechanism of colorectal cancer metastasis.

METHODSHuman colorectal carcinoma cell lines of different metastatic potential, Lovo and SW480 were conventionally cultured, and the protein was extracted. 50% inhibitory concentration (IC(50)) of 5-FU to these two cell lines was measured by MTT assay. Proteins of these two cell lines after intervention by 5-FU at IC(50) were extracted, then 2-dimensional gel electrophoresis was conducted for the proteins. The differential protein spots were examined by mass spectrometry and analyzed by bioinformatics. Difference of expressed proteins in two cell lines before and after the intervention of 5-FU was validated by Western blot and immunofluorescence.

RESULTSEleven differentially expressed proteins were identified by 2-dimensional gel electrophoresis and mass spectrometry. The hnRNP K protein and PDI were selected to be examined by Western blot and immunofluorescence. Results revealed that the expression of hnRNP K in Lovo was higher than that in SW480, while the expression of PDI was lower in Lovo. After intervention by 5-FU at IC(50), the expression of hnRNP K in Lovo decreased more as compared to SW480, while the expression of PDI in SW480 increased more as compared to Lovo.

CONCLUSIONThere are significant differences in expression of hnRNP K and PDI proteins between Lovo and SW480 cell lines, and the proteins alter regularly after 5-FU intervention.
