ObjectiveTo clarify the expression of TRIM28 in non-M3 acute myeloid leukemia （AML） and its correlation with clinical indicators and prognosis， and to further explore the effect of TRIM28 expression levels on the proliferation and apoptosis of AML cells using small interfering RNA. MethodsThe GSE34577 dataset was analyzed using R software to compare TRIM28 expression between healthy controls and non-M3 acute myeloid leukemia （AML） patients. Clinical samples from non-M3 AML patients were collected， with TRIM28 expression levels measured using real-time quantitative PCR （qPCR）. The analysis focused on correlations between TRIM28 expression and various clinical indicators， treatment efficacy， and patient prognosis. Furthermore， small interfering RNA （siRNA） technology was employed to downregulate TRIM28 expression in human primary AML cells （HL60 cell line）. The effects on cell proliferation and apoptosis were then assessed through CCK-8 assays and flow cytometry， respectively. ResultsThe results showed that TRIM28 was up-regulated in non-M3 AML of both online database GSE34577 and clinical samples （P<0.000 1）， TRIM28 expression of new diagnosis group and relapsed refractory group was higher than iron deficiency anemia group （P<0.01）， and there was no significance between different French-American-British classification systems subtype. TRIM28 expression was higher in non-M3 AML patients with a poor genetic prognosis stratified as moderate than in the good prognosis group， and TRIM28 expression was associated with NPM1 combined with the FLT3-ITD mutation， positively correlated with age， bone marrow blast， peripheral blood blast and white blood cell， negatively correlated with hemoglobin. In addition， interference TRIM28 greatly inhibited cell proliferation and promoted cell apoptosis. ConclusionThis study reveals that TRIM28 is highly expressed in non-M3 AML and associated with prognosis， and plays a key role in the proliferation and apoptosis of AML cells， suggesting that TRIM28 may serve as a novel therapeutic target for non-M3 AML.

Objective:To prepare the nanodrug paclitaxel dimer(PTX2)-loaded nanoparticles(NPs)using the block copolymer 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-polyethylene glycol 2000,(DSPE-PEG2000),and to explore the killing effect of PTX2 NPs on the human lung cancer A549 cells and its influence on apop to tis.Methods:The PTX2 NPs were prepared using nanoprecipitation method.Dynamic light scattering(DLS)was employed to determine the particle size distribution,and transmission electron microscope(TEM)was used to observe the ultrastructure of the nanoparticles.After treatment of 0 and 10 mmol·L-1 dithiothreitol(DTT),dialysis method was used to evaluate the in vitro drug release profile of PTX2 NPs.The cell counting kit-8(CCK-8)method was used to assess the survival rates of the A549 cells after treated with PTX2 and PTX2 NPs with different concentrations(0.000 1,0.001 0,0.010 0,0.100 0,and 1.000 0 μmol·L-1).The A549 cells were divided into control group,PTX2 group,and PTX2 NPs group.Live/dead staining method was used to detect the survival of the A549 cells in various groups,and flow cytometry was used to detect the apoptotic rates of the A549 cells in various groups.Results:The mean hydrodynamic diameter of PTX2 NPs was determined to be 144.7nmbyDLS.TheTEM imaging confirmed uniform spherical morphology of PTX2 NPs.In a reductive environment,the PTX2 NPs exhibited continuous drug release with total paclitaxel(PTX)release of 84％within 72 h.The results of CCK-8 method showed that both PTX2 and PTX2 NPs inhibited the proliferation of A549 cells in a dose-dependent manner.When the concentrations of PTX＜0.01 μmol·L-1,compared with PTX2 group,the survival rates of A549 cells in PTX2 NPs group were significantly decreased(P＜0.01 or P＜0.001).The live/dead staining results showed that compared with PTX2 group,the number of red fluorescence-labeled dead cells in PTX2 NPs group was increased.The flow cytometry results demonstrated that compared with control group and PTX2 group,the apoptotic rates of the A549 cells in PTX2 NPs group were significantly increased(P＜0.05 orP＜0.01).Conclusion:The PTX2-loaded nanoparticles PTX2 NPs are successfully prepared which exhibits responsive drug release and demonstrates a more significant killing effect on the human lung cancer A549 cells compared to PTX2.

Objective:To analyze the current preparation and usage situation of first-aid drugs in the rescue vehicles in children's medical institutions, and provide references for optimizing the list of emergency drugs.Methods:First-aid drug lists in the rescue vehicles of 12 children's medical institutions from 11 provinces and municipalities in China were collected through questionnaire surveys, and the drugs as well as their quantities were compared. The existing problems in the use of first-aid drugs in the 12 medical institutions were investigated by on-site interviews. The usage information of first-aid drugs in the rescue vehicles of the General Surgery and Cardiology Department of Shanxi Children's Hospital from May 2022 to April 2023 was collected through the hospital information center, and usage frequency and dosage per patient of the drugs were calculated. Descriptive statistical analysis was conducted on the collected data.Results:The first-aid drug lists in 12 hospitals were various, including 7 to 22 kinds of drugs and involving a total of 23 drugs. These mainly included vasoactive drugs, cardiotonic drugs, antiarrhythmic drugs, antiangina and anti-ischemic drugs for the heart, antispasmodic drugs, diuretics, dehydrating drugs, sedative-hypnotic drugs, and glucocorticoids, all of which were injections. The drugs that were included in all the lists of 12 hospitals were epinephrine, dopamine, dexamethasone, furosemide, and atropine. The drug lists of different rescue vehicles throughout the hospital were the same in 4 hospitals, while the lists varied among departments based on their specific clinical needs in the other 8 hospitals. None of the 12 hospitals had a first-aid drug usage manual. The on-site interview results showed that, the existing problems about drug preparation and use in rescue vehicles mainly involved the following 6 aspects: drug types, quantities, labels, storage, procurement, and usage. In Shanxi Children's Hospital, the types and quantities of first-aid drugs in rescue vehicles of General Surgery Department and Cardiology Department were the same. There were 6 and 9 kinds of drugs were used in the 2 departments during rescue operations, respectively. The drugs that were never used in either department included promethazine, lidocaine, diazepam, phenobarbital, raceanisodamine, sodium bicarbonate, atropine, glucose, and calcium gluconate.Conclusions:The phenomenon of unreasonable kinds and quantities of first-aid drugs in the rescue vehicles existed in the children's medical institutions, and the drugs provided did not fully match the actual clinical needs. There was an urgent need for preparation guidelines and usage manuals of first-aid drugs that were suitable for children's medical institutions to enhance the scientificity of drug supply and the correctness of usage.

Objective To investigate the clinical characteristics and prognosis of acute myeloid leukemia(AML)patients with PTPN11 gene mutation.Methods Total 115 adult AML patients who underwent initial diagnosis,treatment,and second-generation sequencing(NGS)detecting at hospital were recruited in this study.Clinical da-ta included disease characteristics,treatment efficacy,long-term prognosis,immune cell subpopulations,and leu-kemia stem cells were collected to analyze the clinical characteristics and prognosis of AML patients with PTPN11 gene mutation.Results PTPN11 gene mutation rate in newly diagnosed adult AML was 9.57％,and the mutation site mainly occurred in exon 3 region with all mutation type being point mutation.Compared with PTPN11 wild-type group,PTPN11 gene mutation group had a higher early mortality rate(18.18％vs 4.00％,P=0.048),a lower complete response rate(33.33％vs 67.71％,P=0.039),a higher recurrence rate(83.33％vs 42.31％,P=0.043),a shorter median overall survival time(9 months vs 20 months,P=0.026),a lower proportion of ef-fector T cells[(1.39±0.12)％vs(3.56±0.46)％,P=0.038],and a higher proportion of leukemia stem cells[(13.82±3.66)％vs(3.87±1.40)％,P=0.021].Conclusion PTPN11 gene mutation is a poor prognostic marker for AML.Those patients have a high early mortality rate,low complete remission rate,high recurrence rate,short median overall survival time,a low proportion of effector T cells,and a high proportion of leukemia stem cells.

BACKGROUND:After the internal fixation of cannulated screws in femoral neck fractures,because the affected limb is often unable to bear weight in the short term and the implants with high stiffness have a stress shielding effect on the fracture end,it is easy to cause osteoporosis of the affected limb and changes in the biomechanical distribution of the proximal femur,the incidence of osteonecrosis of the femoral head is high after surgery.At present,few studies have been conducted on the biomechanical effects of osteoporosis at the proximal end of the femur occurring after femoral neck fracture surgery on femoral neck fracture treated with cannulated screws. OBJECTIVE:Using finite element analysis,to investigate the biomechanical effects of osteoporosis occurring after femoral neck fracture surgery on femoral neck fracture treated with cannulated screws and explore the role of biomechanical factors in osteonecrosis of the femoral head. METHODS:Based on the obtained CT scan data of the femur in a patient with a femoral neck fracture,a proximal femoral model for internal fixation for femoral neck fracture was established by Mimics 19.0,3-Matic,UG 11.0,Hypermesh 14.0,and Abaqus software.One finite element model of the proximal femur without osteoporosis and three finite element models of the proximal femur with osteoporosis were analyzed using Abaqus software.The stress,contact pressure,displacement peak and cloud map under different components of the four models were measured and analyzed,and the internal stress changes and distribution of the femoral head were compared and analyzed. RESULTS AND CONCLUSION:The stresses and contact pressures of the femoral head and lower anterior cannulated screws varied more with the degree of osteoporosis.The peak displacement of the four models increased slowly with the degree of osteoporosis.By one-way analysis of variance,there was no significant effect of the degree of osteoporosis on the peak stress,contact pressure,and displacement of the different components.The internal stress distribution of the femoral head changed with the degree of osteoporosis.Changes in the biomechanical environment of the proximal femur have an important impact on osteonecrosis of the femoral head.

Objective To comprehensively analyze the effectiveness of exercise training-based respiratory rehabilitation therapy on patients with occupational pneumoconiosis (hereinafter referred to as "pneumoconiosis"). MethodsLiterature on randomized controlled trials of exercise training-based respiratory rehabilitation therapy for pneumoconiosis patients published from the establishment of the database to July 2023 was retrieved from academic systems such as the China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, VIP Database, and China Biology Medicine using bibliometrics method. The RevMan 5.4 software was used for meta-analysis of the selected literatures. Subgroup analysis was conducted to explore the source of study heterogeneity. The funnel plot method was used to test publication bias. Results A total of 55 articles were included, involving 2 436 pneumoconiosis patients in the experimental group and 2 405 pneumoconiosis patients in the control group. The result of random or fixed effect model showed that the six minutes walking distance, the total score of Short from Health Survey-36, forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), FEV₁/FVC, arterial partial pressure of oxygen of pneumoconiosis patients increased after respiratory rehabilitation therapy (all P<0.05), while the total score of the St. George's Respiratory Questionnaire and arterial partial pressure of carbon dioxide decreased compared with the conventional treatment (all P<0.05). The result of subgroup analysis showed that the total score of the St. George's Respiratory Questionnaire, FEV₁, and the index of arterial partial pressure of oxygen of pneumoconiosis patients was better in the rehabilitation treatment for ≥six months compared with those

BACKGROUND: Textbook outcome (TO) can guide decision-making among patients and clinicians during preoperative patient selection and postoperative quality improvement. We explored the factors associated with achieving a TO for gallbladder carcinoma (GBC) after curative-intent resection and analyzed the effect of adjuvant chemotherapy (ACT) on TO and non-TO patients. METHODS: A total of 540 patients who underwent curative-intent resection for GBC at the Department of Hepatobiliary Surgery of the First Affiliated Hospital of Xi'an Jiaotong University from January 2011 to December 2020 were retrospectively analyzed. Multivariable logistic regression was used to investigate the factors associated with TO. RESULTS: Among 540 patients with GBC who underwent curative-intent resection, 223 patients (41.3%) achieved a TO. The incidence of TO ranged from 19.0% to 51.0% across the study period, with a slightly increasing trend over the study period. The multivariate analysis showed that non-TO was an independent risk factor for prognosis among GBC patients after resection ( P = 0.003). Age ≤60 years ( P = 0.016), total bilirubin (TBIL) level ≤34.1 μmol/L ( P <0.001), well-differentiated tumor ( P = 0.008), no liver involvement ( P <0.001), and T1-2 stage disease ( P = 0.006) were independently associated with achieving a TO for GBC after resection. Before and after propensity score matching (PSM), the overall survival outcomes of non-TO GBC patients who received ACT and those who did not were statistically significant; ACT improved the prognosis of patients in the non-TO group ( P <0.05). CONCLUSION Achieving a TO is associated with a better long-term prognosis among GBC patients after curative-intent resection, and ACT can improve the prognosis of those with non-TO.
