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.

Miao medicine is guided by the medical theories of the Miao ethnic group,and the drugs used by the Miao people are derived from natural plants and animals for the prevention and treatment of diseases and protection of health.In recent years,a large number of clinical studies have shown good clinical efficacy of traditional Miao medicine in the treatment of prostatic diseases,with the advantages of easy availability,low price,and minimal adverse reactions.However,currently no systematic literature review has been reported on the treatment of prostatic diseases with Miao medicine.This article focuses on the commonly used Miao drugs recorded in the Chinese Materia Medica-Miao Medicine,with a systematic review of relevant literature retrieved on the treatment of prostate disea-ses with Miao medicine in recent years and a summarization of the advances in the studies of its pharmacological effects,mechanisms of action and clinical application,aiming to provide some new perspectives and ideas for further academic research and clinical develop-ment of Miao medicine.

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 analyze the prevalence trend and spatiotemporal distribution characteristics of congenital heart disease in China.Methods:Data on the incidence of congenital heart disease in China and provinces from 2002 to 2021 were collected through publicly available literature and reports. Joinpoint regression was used to assess the temporal trend of the incidence of congenital heart disease. Spatial autocorrelation analysis and spatiotemporal scanning statistics were used to analyze the spatial aggregation of hotspots and clustering areas of congenital heart disease occurrence.Results:The incidence of congenital heart disease in China showed a continuously increasing trend from 2002 to 2021, with an average annual increase of 15.33% (AAPC=15.33%, P<0.001). Except for areas with missing data, 25 provinces showed an increasing trend (all AAPC>0, all P<0.05), while there was no significant change in Guangdong and Guangxi ( P=0.397 and 0.081). The results of global autocorrelation analysis showed that the occurrence of congenital heart disease had a certain clustering distribution, with the Global Moran′s I>0 in 2005, 2006 and 2016, which were 0.23, 0.26 and 0.23 ( P=0.027, 0.017 and 0.022). The results of local spatial autocorrelation showed that Hunan, Jiangxi and Fujian were high-high clustering areas, while the central and southwestern regions were low-low clustering areas. The results of segmental spatiotemporal scanning showed that eight clustering areas were found in four time periods ( P≤0.001), and the clustering areas showed a trend of gradually expanding from none to certain coverage. Conclusion:From 2002 to 2021, the overall trend of congenital heart disease in China has been on the rise, with a certain degree of spatial aggregation. The clustering areas of spatiotemporal scanning have gradually increased, and the scope has gradually expanded.

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:To investigate the clinical characteristics of limb overgrowth following proximal femoral osteotomy (PFO) for unilateral developmental dysplasia of the hip (DDH) in children.Methods:A retrospective analysis was conducted on 36 children with unilateral DDH who underwent PFO at Xi'an Honghui Hospital from June 2017 to June 2021. The cohort included 4 males and 32 females, with a mean age of 4.23±3.15 years (range: 2-12 years), comprising 28 left-sided and 8 right-sided cases. According to the International Hip Dysplasia Institute (IHDI) classification, there were 2 type I, 9 type II, 16 type III, and 9 type IV cases. Radiographic parameters [femoral length, femoral neck anteversion angle, neck-shaft angle, acetabular index (AI), center-edge angle (CEA), center-head distance discrepancy (CHDD)] and PFO parameters (varus angle, shortening length, derotation angle) were measured on X-ray and 3D CT reconstructions. Comparisons were made between the overgrowth ≥1 cm group ( n=14) and <1 cm group ( n=22) to analyze risk factors and patterns. Results:The overgrowth ≥1 cm group had significantly younger patients (2.49±1.03 years vs. 5.13±3.47 years, t=-2.757, P<0.001). Overgrowth magnitude varied significantly across age subgroups: 11.08±6.17 mm in the 2-4 years group, 5.08±0.19 mm in the >4-<6 years group, and 2.44±4.50 mm in the ≥6 years group ( F=5.436, P=0.031). The highest incidence of overgrowth occurred in the 2-4 years subgroup (56%, 20/36). Limb overgrowth initiated at 3 months postoperatively, exhibited a linear correlation with follow-up duration during 6-18 months [ r=0.78, 95% CI(0.62, 0.88), P<0.001)], and plateaued after 18 months [ r=-0.15, 95% CI(-0.75, 0.57), P=0.710]. Postoperative CEA and CHDD showed significant improvements ( P<0.05), while AI remained unchanged ( P>0.05). Conclusions:Children aged 2-4 years exhibit higher incidence and severity of post-PFO limb overgrowth. The rapid progression phase occurs within 6-18 months postoperatively, stabilizing thereafter. CEA and CHDD serve as critical indicators for evaluating intervention efficacy in DDH-related overgrowth.

Objective To investigate the outcome of endovascular aortic repair under digital subtraction angiography (DSA) in the treatment of Stanford type B aortic dissection (TBAD). Methods A total of 104 TBAD patients admitted to our hospital from October 2019 to October 2022 were selected,of which 52 patients treated with best medication treat (BMT) were included into the BMT group,and 52 patients who underwent endovascular aortic repair under DSA on the basis of BMT were included into the combination group. The acute physiological and chronic health evaluation Ⅱ (APACHE Ⅱ) score,serum inflammatory indicators,liver and kidney function indicators,and coagulation function indicators before and after treatment,and hospital stay were compared between the two groups. Results The APACHE Ⅱ score,liver and kidney function indicators and inflammatory factors after treatment in the combination group were lower than those before treatment and in the BMT group (P<0.05). The combination group had more significant changes of coagulation function indicators after treatment than those before treatment and in the BMT group (P<0.05). The hospital stay of the combination group was shorter than that of the BMT group (P<0.05). Conclusion Endovascular aortic repair under DSA for TBAD can reduce inflammatory response,improve liver and kidney functions and coagulation function,and shorten the hospital stay,which has a better therapeutic effect than conservative drug treatment.

Radiation-induced esophageal injury (RIEI) is a frequent complication following radiotherapy for thoracic and head-neck malignancies, which may lead to severe sequelae including esophageal stricture and perforation, adversely affecting patients' quality of life and therapeutic outcomes. With advancements in radiotherapy techniques — particularly the adoption of unconventional fractionation regimens, concurrent chemoradiotherapy, and combined molecular targeted / immunotherapy — the incidence of RIEI has been increasing. In this review, recent advances in understanding the pathogenesis, clinical manifestations, risk factors, and management strategies for RIEI were comprehensively summarized. Current therapeutic approaches have evolved beyond conventional anti-inflammatory and nutritional support to include novel interventions such as targeted therapy, free radical scavengers, and microbiota modulation, etc. Future research should prioritize the development of optimized, individualized prevention and treatment protocols to mitigate RIEI risk and improve patient prognosis.

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.
