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 investigate the epidemiological characteristics of malaria and provide a basis for developing improved prevention and control measures. Methods Data were obtained from the Chinese Disease Prevention and Control Information System. Malaria surveillance data for Nanning City from January 1,2023, to December 31,2024, were exported from the Infectious Disease Reporting Information Management Subsystem. The characteristics of the two groups of malaria cases were compared. Results A total of 103 imported malaria cases were reported in Nanning City in 2024, representing a 38.32% decrease compared with the same period of the previous year. No statistically significant difference were observed between cases reported in 2023 and 2024 in terms of average age, gender ratio, proportion of parasite species, and monthly reporting distribution;however, statistically significant differences were found in the proportion of reporting areas and current residence areas(χ2= 13.572 and 10.355, respectively; P = 0.001 and 0.035, respectively). The proportion of cases reported in Shanglin County and the proportion of cases residing in Shanglin County were both lower than those during the same period of the previous year. Conclusions The high aggregation of imported malaria cases in Nanning City has decreased. Medical institutions in areas other than Shanglin County should strengthen their vigilance against malaria.

Aim To study whether intravenous injec-tion of miR-129-3p mimetic(agomir)can resist bone loss caused by hind limb disuse,and to provide new i-deas for preventing bone loss in microgravity environ-ment.Methods Forty-eight C57BL/6J male mice were randomly divided into the control group(CON),tail suspension model group(TS),tail suspension+miR-129-3p agomir administration group(miRNA)and tail suspension+miR-129-3p negative sequence agomir control group(NC).The miRNA group was given 4 mg·kg-1 miR-129-3p agomir by intravenous injection into the medial canthus twice a week.The NC agomir group were consistent with those in the miR-129-3p agomir group,and the CON and TS groups were given only equal volumes of normal saline.After four weeks,all mice were sacrificed and samples were collected.Micro-CT scan of femur,three-point femur bending test,serum bone metabolism index detection,oxidative stress index detection and osteogenesis-related protein expression analysis in bone tissue were per-formed.Results After four weeks,the number of tra-becular bone in the TS group was significantly re-duced,and Tb.BMD,Tb.Th,Tb.N,Tb.BS/TV and Tb.BV/TV were significantly lower than those in the CON group(P＜0.01).While Tb.Sp TS group was significantly higher than the CON group(P＜0.05),the maximum load and flexural strength of the femur significantly decreased(P＜0.01),the content of ser-um bone formation index PINP was significantly lower than that of the CON group(P＜0.01),and the con-tent of bone resorption index CTX-I was significantly higher than that of the CON group(P＜0.01),the content of serum oxidative damage indexes 8-iso-PGF2α and 8-OHdG significantly increased(P＜0.01),and the expression of osteogenesis-related pro-teins in bone tissue markedly decreased(P＜0.01).However,the increase or decrease of all indexes in miRNA group was significantly lower than that in TS group.Conclusions miR-129-3p mimetic can signifi-cantly reduce bone loss caused by hind limb disuse.This experiment provides a new idea and method for preventing bone loss in microgravity environment.

Objective To investigate the clinical efficacy of dual-layer artificial dermis combined with vacuum sealing drainage and autologous split-thickness skin graft in the treatment of chronic refractory wounds.Methods A total of 60 patients with chronic refractory wounds were prospectively selected and divided into the control group(30 cases)and the observation group(30 cases)according to random number table method.In the control group,patients were treated with simple vacuum sealing drainage in the first phase and autologous split-thickness skin graft in the second phase.In the observation group,patients received dual-layer artificial dermis combined with vacuum sealing drainage in the first phase and autologous split-thickness skin graft in the second phase.The survival of autologous split-thickness skin,the incidence of adverse reactions,and the degree of scarring[Vancouver scar scale(VSS)score]of patients in the two groups were observed.The degree of pain before and after treatment[visual analogue scale(VAS)score],serum matrix metalloproteinase 13(MMP-13)level,serum tissue inhibitor of metalloproteinase 1(TIMP-1)level,and MMP-13/TIMP-1 ratio of patients in the two groups were compared before and after treatment.Results After treatment,the survival rate of autologous split-thickness skin in the observation group was better than that in the control group,the incidence of adverse reactions,the VSS score of the graft site and the donor site,and the pain degree in the observation group was lower/lighter than those in the control group,and the above differences were statistically significant(P<0.05).After treatment,the serum MMP-13 level and MMP-13/TIMP-1 ratio of patients in the two groups were lower than those before treatment,and the serum TIMP-1 level was higher than that before treatment,and the changes in the observation group were greater than that in the control group,and the differences were statistically significant(P<0.05).Conclusion Dual-layer artificial dermis combined with vacuum sealing drainage and autologous split-thickness skin graft have significant effects in the treatment of chronic refractory wounds,which can increase the survival rate of autologous split-thickness skin,reduce adverse reactions,alleviate scar conditions and pain degree,and regulate serum MMP-13 and TIMP-1 levels.

Objective In order to understand the current status and influencing factors of perioperative pulmonary rehabilitation knowledge,attitude,and practice among Chinese thoracic surgery nurses,and to provide references for managers to take targeted measures to improve their pulmonary rehabilitation knowledge,attitude,and practice level.Methods From August to October 2023,a convenience sampling method and cross-sectional descriptive survey were used to anonymously survey 1 167 thoracic surgery nurses from tertiary-level A cancer specialty hospitals and tertiary-level A general hospitals in 24 provinces through the Wenjuanxing platform.A general information questionnaire and a knowledge,attitude and practice questionnaire for lung cancer perioperative pulmonary rehabilitation nurses were used,including knowledge dimension(14 items),belief dimension(6 items),and behavior dimension(14 items),totaling 34 items.Univariate analysis and linear regression multivariate analysis were used to determine the influencing factors of the knowledge,attitude and practice level of thoracic surgery nurses in perioperative pulmonary rehabilitation.Results 1 089 nurses completed the investigation.The total standard score and the dimension scores on knowledge,attitude,and behavior of the perioperative pulmonary rehabilitation questionnaire for thoracic surgery nurses were(80.45±11.84)(73.72±14.68)(89.61±11.38)and(83.46±14.48),respectively.The nature of the hospital,whether there is an administrative position,whether the department carries out ERAS,and whether they have received pulmonary rehabilitation training are the influencing factors of the perioperative pulmonary rehabilitation knowledge,attitude,and practice level of thoracic surgery nurses(P＜0.05).Conclusion The knowledge,attitude,and practice of perioperative lung rehabilitation among thoracic surgery nurses are generally at a moderate level.However,their knowledge of perioperative lung rehabilitation is relatively insufficient,and there are many influencing factors.Managers should strengthen pulmonary rehabilitation training for thoracic surgery nurses,improve their knowledge reserves and evidence conversion capabilities,and coordinate cross-integration among multidisciplinary teams to improve their knowledge,attitude and practice in perioperative pulmonary rehabilitation.
