Flap transplantation is a critical surgical strategy for the reconstruction of tissue defects caused by trauma, tumor resection, and congenital malformations, and its survival rate directly determines surgical efficacy and patient prognosis. Following transplantation, flaps inevitably undergo ischemia-reperfusion (I/R) injury, during which oxidative stress, inflammatory responses, and metabolic disturbances are intricately intertwined, ultimately leading to cellular injury and tissue necrosis. Recent studies have demonstrated that multiple forms of programmed cell death—including apoptosis, pyroptosis, ferroptosis, necroptosis, and PANoptosis—play central roles in flap I/R injury. The extensive crosstalk and molecular interactions among these pathways form a highly complex cell death network. Specifically, apoptosis is mediated by the imbalance of Bcl-2 family proteins and the activation of cysteine-dependent aspartate-specific protease (caspase) cascades; pyroptosis is driven by the NLRP3-caspase-1-GSDMD axis, resulting in membrane pore formation and the release of pro-inflammatory cytokines; ferroptosis is characterized by iron-dependent lipid peroxidation and dysfunction of glutathione peroxidase 4 (GPX4); necroptosis is triggered by the receptor-interacting serine/threonine-protein kinase 1 (RIPK1)-RIPK3-MLKL signaling complex, leading to membrane rupture; and PANoptosis represents an integrated form of inflammatory cell death that coordinates multiple death pathways. Importantly, these forms of programmed cell death are not independent but are interconnected through extensive signaling crosstalk. Key regulatory molecules, including caspase-8, reactive oxygen species (ROS), nuclear factor-κB (NF-κB), and nuclear factor erythroid 2-related factor 2 (Nrf2), collectively modulate the dynamic balance among these pathways. Therefore, the multidimensional interplay and spatiotemporal dynamics of programmed cell death constitute a fundamental pathological basis of flap I/R injury. This review systematically summarizes the latest advances in the mechanisms and interactions of various programmed cell death pathways in flap I/R injury, aiming to elucidate the underlying regulatory network. These insights may provide novel theoretical foundations for optimizing flap protection strategies, improving flap survival, and promoting tissue repair.

Objective To investigate the impact of osteotomy mode on the callus morphology in the ex-tension area of tibial bone transfer and its efficacy.Methods The information of the patients with bone defect treated in 910 Hospital of Joint Logistics and Security Force of Chinese People's Liberation Army from May 2016 to June 2022 was collected.By comparing the general data of the patients with different osteotomy meth-ods(minimally invasive osteotomy group,subperiosteal osteotomy group and extraperiosteal osteotomy group),callus morphology in the extension area(sunken type,uniform type and protruding type),healing in-dex,Ilizarov Method Research and Application Society(ASAMI)bone healing and functional evaluation and other information,the curative effect differences of different osteotomy methods on tibial bone transfer were investigated.Results The incidence rate of sunken type of callus in the extension area was 15.8%in the mini-mally invasive osteotomy group,18.9%in the subperiosteal osteotomy group,and 14.3%in the extraperioste-al osteotomy group,with statistically significant differences among the three groups(P<0.05);in which,the incidence of sunken type of callus in the minimally invasive osteotomy group was lower than that in the subpe-riosteal osteotomy group(χ2=10.178,P=0.005),but there was no statistically significant difference when compared to the extraperiosteal osteotomy group(χ2=0.102,P=0.814),the difference betrrween the extra-periosteal osteotomy group and subperiosteal osteotomy group also had no statistical difference(χ2=0.084,P=0.772).The incidence rate of uniform type of callus in the minimally invasive osteotomy group was lower than that in the subperiosteal osteotomy group(χ2=6.579,P=0.013),but there was no statistically signifi-cant difference when compared to the extraperiosteal osteotomy group(χ2=0.443,P=0.506).The difference in the subperiosteal osteotomy group and extraperiosteal osteotomy group also had no statistically significant(χ2=2.602,P=0.107).The incidence rate of protruding type of callus in the minimally invasive osteotomy group was higher than that in the subperiosteal osteotomy group(χ2=9.795,P=0.002),and the incidence rate of protruding type of callus in the extraperiosteal osteotomy group was higher than that in the subperios-teal osteotomy group(χ2=5.170,P=0.023),however,there was no statistically significant difference be-tween the minimally invasive osteotomy group and the extraperiosteal osteotomy group(χ2=0.308,P=0.579).There were no statistically significant differences in healing index,ASAMI scores,contact point non-union,pin tract infection and refracture incidence rate rates among the three groups(P>0.05).Conclusion Sub-periosteal osteotomy in the single plane tibial bone moving does not show the expected results in favor of the extension area mineralization,on the contrary,extraperiosteal osteotomy has the similar clinical efficacy to minimally invasive osteotomy.

The Healthy China 2030 Plan set the goal of reducing premature deaths from diabetes by 30% by 2030. However, there has been a lack of assessment of premature mortality for diabetes since the action plan was issued. This study used data from the Global Burden of Disease Study 2021, calculated the premature deaths for diabetes by sex, provinces, and subtypes from 1990 to 2021. We explored the temporal trend of premature mortality using the average annual percent change (AAPC) for different sexes, provinces, and subtypes from 1990 to 2021. Furthermore, we predicted premature mortality for diabetes through 2030 for China and its provinces according to the average annual change rate from 2010 to 2021. There was a first slow upward trend in premature mortality for diabetes from 0.5% in 1990 to 0.6% in 2004, and then a decline until 2021 with premature mortality of 0.4%. By 2030, only Fujian (30.3%) will achieve the desired level of reduction, with only seven provinces meeting the target for females and none for males. There is a large range in the degree of decline between inland and coastal regions, showing obvious geographic differences, and there should be a focus on balancing medical resources.

To clarify the genetic diversity and structure of the nucleus population of F1-generation Litopenaeus vannamei, this study utilized 15 pairs of highly polymorphic microsatellite primers to analyze the simple sequence repeat (SSR) markers and genetic diversity in 15 full-sib families of L. vannamei. A total of 112 alleles (N_a) and 60.453 effective alleles (N_e) were identified among the selected 15 SSR loci, with the average polymorphic information content (PIC) of 0.648. The average N_e, observed heterozygosity (H_o), and expected heterozygosity (H_e) in the 15 F1 families varied from 1.925 to 2.626, 0.425 to 0.783, and 0.403 to 0.572, respectively. The 15 full-sib families were primarily clustered into three categories in the phylogenetic analysis, with the genetic distance between families ranging from 0.252 to 0.574. Additionally, the genetic differentiation coefficient (F_st) among the families varied from 0.112 to 0.278, indicating substantial genetic differentiation. Overall, this study suggested that the genetic diversity of the 15 full-sib families was moderate, providing valuable genetic insights for the subsequent breeding initiatives aimed at enhancing the tolerance of L. vannamei to high levels of soybean meal.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
