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 examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

Objective:Through the comparative analysis of the payment program for the therapeutic value of Traditional Chinese Medicine dominant diseases in 8 provinces,we found the shortcomings of the existing program and put forward the perfect policy suggestions.Methods:Comparative analysis of the core content of the programs in various places,the selection of disease types,efficacy evaluation indexes,the application of the payment link and the protection mechanism.Results:The fragmentation of existing programs is an obvious problem,the specific content settings of each item are quite different,reflecting differences in the understanding of the core content of the program,the existence of inconsistent understanding of Chinese medicine's therapeutic value,the failure to link the payment standard to the results of the therapeutic value evaluation,and the lack of recognition of the value of Chinese medicine's technical labor,among other problems.Conclusions:We can select disease types based on the prominent advantages of Traditional Chinese medicine,learn from the evaluation framework of western medicine value-based medical care,construct the evaluation system of Chinese medicine therapeutic value,and carry out"equal price"payment based on the"same effect"of health results,set performance indicators and payment standards in stages,realize the whole process management of disease,and enhance the Traditional Chinese Medicine's therapeutic value,and promote the development of Traditional Chinese Medicine inheritance and innovation.

Background and purpose:Melanoma is a highly invasive malignant tumor originating from melanocytes,which poses a great threat to human life and health around the world,and its morbidity and mortality have been rising continuously in recent years.Telomerase and autophagy play crucial roles in cell proliferation,survival and stress response.Telomerase maintains the replication ability of cells by prolonging telomeres at the ends of chromosomes,and autophagy,as a self-degradation mechanism of cells,can not only help cells remove damaged components to promote survival,but also induce cell death under certain conditions.In the tumor environment,they are often abnormally activated or out of balance,and participate in the occurrence and development of many cancers,including melanoma.This study investigated the roles of telomerase and autophagy in melanoma progression and evaluated the potential synergistic therapeutic effects of combined application of telomerase inhibitor BIBR1532 and autophagy inhibitor chloroquine(CQ)in melanoma treatment.Methods:Malignant melanoma cells A375 were treated with telomerase inhibitor BIBR1532.The cell viability was assessed using the cell counting kit-8(CCK-8)assay,and the cell apoptosis was detected using the Annexin Ⅴ/propidium iodide(PI)double staining method.Additionally,the expressions of autophagy-related proteins LC3-Ⅱand p62 were detected by Western blot,and the changes in autophagy flux were observed using dual-tagged adenovirus transfection technology.Based on these studies,BIBR1532 and the autophagy inhibitor CQ were further applied in combination to analyze cell proliferation,apoptotic rate,changes in mitochondrial membrane potential,and cell cycle distribution,and the cloning formation experiment was used to verify the cell's proliferative capacity,thereby comprehensively evaluating the efficacy of this combined treatment strategy.Results:Telomerase inhibitor BIBR1532 at a concentration of 50 μmol/L significantly inhibited the growth of malignant melanoma cells A375 and induced apoptosis.At the same concentration,BIBR1532 upregulated the expression of the autophagy-related protein LC3-Ⅱ in A375 cells,while downregulating the expression of p62 protein.By transducing A375 cells with a dual-tagged adenovirus,it was observed that autophagy flux was significantly enhanced after treatment with BIBR1532.Furthermore,the combined application of BIBR1532(50 μmol/L)and the autophagy inhibitor CQ(20 μmol/L)significantly promoted the death of A375 cells,induced apoptosis and destruction of mitochondrial membrane potential,caused cell cycle arrest at the G2/M phase,and significantly inhibited the cell's clonogenic ability.Conclusion:Telomerase inhibitor BIBR1532 not only inhibits the proliferation of malignant melanoma cells but also activates the autophagy process in these cells,and inhibition of the autophagy response by autophagy inhibitor CQ can enhance the sensitivity of malignant melanoma cells to telomerase inhibitor BIBR1532.

AIM To investigate the therapeutic mechanism of tanshinone ⅡA in a mouse model of chronic colitis induced by trinitrobenzene sulfonic acid(TNBS).METHODS The BALB/c mice were randomly divided into the control group,the model group,and the low-dose and high-dose tanshinone ⅡA groups(10,20 mg/kg).Chronic inflammatory bowel disease(IBD)was induced in the model and tanshinone ⅡA groups by epicutaneous application of 3.75 mg TNBS(dissolved in 48％ethanol),followed by intrarectal administration of TNBS(0.75,1.5 and 2.25 mg in 40％ethanol)on days 7,14 and 21.Starting on day 7 post-modeling,the mice underwent their 14-day consecutive dosing of corresponding drugs by gavage.The mice had their disease activity index(DAI)assessed;their colon length and weight measured;and their levels of inflammatory factors IFN-γ and TNF-α in the colon mucosa detected by ELISA.The wild-type and PXR-/-mice were randomly divided into the control group,the model group,and the tanshinone ⅡA group(20 mg/kg).After modeling and drug administration using the aforementioned method,Masson staining was used to assess the intestinal fibrosis;immunohistochemistry was employed to detect the colon expression of ZO-1 and Occludin proteins;and immunofluorescence was used to detect the colon expression of NF-κB p65.RESULTS Tanshinone ⅡA(20 mg/kg)reduced DAI scores,colon weight/length ratio,and the colon levels of IFN-γ and TNF-α of the mouse models(P＜0.05,P＜0.01).Compared with the WT control group,the WT model group and PXR-/-control group exhibited increased colon histopathological scores and fibrosis areas(P＜0.01),decreased protein expressions of ZO-1 and Occludin(P＜0.01),and increased expression of p-NF-κB p65(P＜0.01).Compared with the WT model group,the WT tanshinone ⅡA group showed reduced colon weight/length ratio,histopathological scores,and fibrosis areas(P＜0.01);increased protein expressions of ZO-1 and Occludin(P＜0.05,P＜0.01);and decreased expression of p-NF-κB p65(P＜0.01).However,tanshinone ⅡA showed no significant therapeutic effect upon PXR-/-model mice(P＞0.05).CONCLUSION Tanshinone ⅡA(20 mg/kg)can effectively alleviate TNBS-induced chronic colitis in mice,and this protective effect may be exerted by the modulation of PXR/NF-κB signaling pathway.

Objective To investigate the antimicrobial resistance of clinical isolates from elderly patients(≥65 years)in major medical institutions across China.Methods Bacterial strains were isolated from elderly patients in 52 hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program during the period from 2015 to 2021.Antimicrobial susceptibility test was carried out by disk diffusion method and automated systems according to the same CHINET protocol.The data were interpreted in accordance with the breakpoints recommended by the Clinical and Laboratory Standards Institute(CLSI)in 2021.Results A total of 514 715 nonduplicate clinical isolates were collected from elderly patients in 52 hospitals from January 1,2015 to December 31,2021.The number of isolates accounted for 34.3％of the total number of clinical isolates from all patients.Overall,21.8％of the 514 715 strains were gram-positive bacteria,and 78.2％were gram-negative bacteria.Majority(90.9％)of the strains were isolated from inpatients.About 42.9％of the strains were isolated from respiratory specimens,and 22.9％were isolated from urine.More than half(60.7％)of the strains were isolated from male patients,and 39.3％isolated from females.About 51.1％of the strains were isolated from patients aged 65-＜75 years.The prevalence of methicillin-resistant strains(MRSA)was 38.8％in 32 190 strains of Staphylococcus aureus.No vancomycin-or linezolid-resistant strains were found.The resistance rate of E.faecalis to most antibiotics was significantly lower than that of Enterococcus faecium,but a few vancomycin-resistant strains(0.2％,1.5％)and linezolid-resistant strains(3.4％,0.3％)were found in E.faecalis and E.faecium.The prevalence of penicillin-susceptible S.pneumoniae(PSSP),penicillin-intermediate S.pneumoniae(PISP),and penicillin-resistant S.pneumoniae(PRSP)was 94.3％,4.0％,and 1.7％in nonmeningitis S.pneumoniae isolates.The resistance rates of Klebsiella spp.(Klebsiella pneumoniae 93.2％)to imipenem and meropenem were 20.9％and 22.3％,respectively.Other Enterobacterales species were highly sensitive to carbapenem antibiotics.Only 1.7％-7.8％of other Enterobacterales strains were resistant to carbapenems.The resistance rates of Acinetobacter spp.(Acinetobacter baumannii 90.6％)to imipenem and meropenem were 68.4％and 70.6％respectively,while 28.5％and 24.3％of P.aeruginosa strains were resistant to imipenem and meropenem,respectively.Conclusions The number of clinical isolates from elderly patients is increasing year by year,especially in the 65-＜75 age group.Respiratory tract isolates were more prevalent in male elderly patients,and urinary tract isolates were more prevalent in female elderly patients.Klebsiella isolates were increasingly resistant to multiple antimicrobial agents,especially carbapenems.Antimicrobial resistance surveillance is helpful for accurate empirical antimicrobial therapy in elderly patients.

Purpose Discover new prostate cancer-related single nucleotide variants.Methods Tissue wax blocks from 21 prostate cancer patients who underwent radical surgery and had relatively complete clinical data were collected for somatic mutation detection to analyze new mutated genes associated with prostate cancer.The levels of cor-responding proteins in the urine of prostate cancer patients were tested according to the results of the selected genes.Results All 21 prostate cancer patients showed obvious somatic mutations,and the mutation types were dominated by C＞T and G＞A.The number of somatic mutations was 521,of which 27 genes had high mutation proportions(≥2 ca-ses),including ZSWIM6(5/21),FOXA1(4/21),SPTA1(2/21),FAM47C(2/21),FLG2(2/21),PRSS3(2/21),TP53(2/21),FLG(2/21),UBR4(2/21),and the mutations occurring in ZSWIM6 were all deletion muta-tions,and the mutations occurring in FOXA1 were missense mutations,deletion mutations,and deletion insertion mu-tations.The urinary levels of UPF1,SPTA1,and IDH1 proteins of the 10 prostate cancer patients were significantly different than those of the healthy controls.Correlation analysis showed that FOXA1 was positively correlated with UBR4(r=0.669,P=0.001),SPTA1 was positively correlated with FLG2(r=1.000,P＜0.001),FAM47C was positively correlated with PRSS3(r=1.000,P＜0.001),and there was a significant positive correlation between TP53 and FLG(r=1.000,P＜0.001).ZSWIM6 and FOXA1 were not correlated with biochemical recurrence.SP-TA1 mutation affected progression-free survival(PFS)[(66.0±0)months vs(30.0±7.8)months,P=0.008].FAM47C was positively correlated with PFS[(66.0±0)months vs(19.0±0)months,P＜0.001].ZNF676 was correlated with PFS[(66.0±0)months vs(26.0±5.0)months,P=0.008].FLG2 was correlated with PFS[(66.0±0)months vs(30.0±7.8)months,P=0.008].PRSS3 was correlated with PFS[(66.0±0)months vs(19.0±0)months,P＜0.001].Conclusion All 21 prostate cancer patients harbored somatic mutations,including ZSWIM6(5/21)and FOXA1(4/21)mutations.SPTA1,FAM47C,ZNF676,FLG2,and PRSS3 may be associated with prognosis.

Objective:To observe any impact of supplementing conventional rehabilitation training with electrothermal acupuncture on the upper limb motor functioning of hemiplegic stroke survivors.Methods:Thirty-six hemiplegic persons who had recently survived a stroke were divided at random into an electrothermal acupuncture group ( n=18) and a control group ( n=18). Both groups received conventional rehabilitation training, while the electrothermal acupuncture group was additionally provided with daily 30-minute sessions of electrothermal acupuncture, 6 days per week for 3 weeks. Before and after the treatment everyone′s upper limb motor functioning was quantified using the Fugl-Meyer assessment (FMA-UE), and their ability in the activities of daily living (ADL) was assessed using the modified Barthel index (MBI). The Hong Kong version of the functional test for the hemiplegic upper extremity (FTHUE-HK) was also administered. Surface electromyography (sEMG) was employed to compute the co-contraction ratios (CRs) of the agonist to antagonist muscles during elbow flexion and extension. Results:After the treatment, both groups exhibited significant improvements in their average FMA-UE, FTHUE-HK and MBI results, but with significantly greater improvement in the electrothermal acupuncture group. The root mean square values of the wrist flexor and extensor and elbow flexor muscles during flexion showed significant improvement in both groups, with the average values in the electrothermal acupuncture group significantly better than those of the control group. The CR values during elbow extension in the electrothermal acupuncture group demonstrated significant improvement compared to before the treatment.Conclusions:Supplementing conventional rehabilitation measures with electrothermal acupuncture can better increase the strength of the elbow and wrist extensor muscles in the early days after a stroke. It promotes the recruitment of muscle fibers in the extensor muscle group, reduces abnormal coordination patterns in the elbow joint, and improves upper limb motor function, the practicality of hand function, and ability in the activities of daily living.

BACKGROUND:For patients with anterior cruciate ligament re-rupture after reconstruction with abnormally increased posterior slope of the tibial plateau,anterior cruciate ligament reconstruction combined with anterior closing-wedge high tibial osteotomy was performed.However,there is a lack of precise tools for osteotomy.OBJECTIVE:To investigate the effectiveness of three-dimensional(3D)printed accurate osteotomy template in anterior cruciate ligament revision for patients with excessive posterior slope.METHODS:The medical records of 30 patients who underwent anterior cruciate ligament revision combined with anterior closing-wedge high tibial osteotomy were retrospectively collected and divided into two groups according to the operation method.The trial group(n=15)was assisted by 3D printing osteotomy guide plate.The control group(n=15)was conventional surgery.The osteotomy time,fluoroscopy times,intraoperative and 24 hours postoperative blood loss,preoperative and 3 months postoperative tibiofemoral anatomical angle,medial proximal tibial anatomical angle,posterior slope,the difference between planned posterior slope correction angle and actual correction angle,and KT-2000 side-to-side difference before operation,3 and 24 months after operation were compared between the two groups.Lachman test and Pivot shift test were performed before operation,immediately after operation,and 24 months after operation.International Knee Documentation Committee score and Lysholm score were performed before operation,3 and 24 months after operation.RESULTS AND CONCLUSION:(1)The osteotomy time,fluoroscopy times,and blood loss during operation and 24 hours after operation in the trial group were significantly less than those in the control group(P＜0.05).(2)The posterior slope of the two groups decreased significantly after operation.There was no significant change in tibiofemoral anatomical angle and medial proximal tibial anatomical angle after operation.The difference between preoperative planned and postoperative actual posterior slope degree in the trial group(0.64±0.41)° was smaller than that in the control group(2.18±0.54)°,and the difference was statistically significant(P＜0.001).(3)The KT-2000 side-to-side difference was significantly reduced in both groups after surgery(P＜0.05).At 3 and 24 months after operation,there was no significant difference in KT-2000 side-to-side difference between the two groups(P＞0.05).The Lachman test and Pivot shift test of the two groups were negative immediately after operation,3 and 24 months after operation.(4)The International Knee Documentation Committee and Lysholm scores of the two groups increased significantly after surgery(P＜0.05).At 3 months after operation,the International Knee Documentation Committee score and Lysholm score of the trial group were significantly higher than those of the control group(P＜0.05).At 24 months after operation,there was no significant difference in International Knee Documentation Committee score and Lysholm score between the two groups(P＞0.05).(5)In conclusion,with the assistance of 3D printing accurate osteotomy guide plate,anterior cruciate ligament reconstruction combined with anterior closing-wedge high tibial osteotomy is easier to operate,with shorter operation time,fewer fluoroscopy times,less intraoperative and postoperative blood loss,and faster recovery of knee joint function after operation,which has high clinical application value.
