A 42-year-old female patient presented with a complete ear amputation resulting from a collision with a machine. The ear was avulsed by blunt trauma, meaning that it was torn away rather than being cleanly cut. Fortunately, the auricular cartilage remained intact and preserved its overall shape despite the amputation. However, the surrounding blood vessels were not suitable for microanastomosis. In the first-stage operation, the auricular cartilage was de-epithelialized and embedded into the postauricular area. Three months later, during the second-stage operation, the embedded auricular cartilage framework was elevated to achieve normal auricular projection. During the postoperative period, a customized mold based on the shape of the patient’s contralateral ear was fabricated using 3D printing technology and applied to the reconstructed ear to refine the contour and achieve a natural appearance. The overall outcome was favorable, with no complications observed during the postoperative care period.

We report the first identification in Korea of the rare ABO*AW31.02-05 allele in a patient with an ABO discrepancy.Forward ABO typing demonstrated a clear B phenotype, whereas reverse typing showed no agglutination. Molecular analysis revealed an ABO*AW31.02-05/B.01 genotype. In silico prediction using PolyPhen-2 and SIFT indicated that both amino acid substitutions (p.Phe216Ile and p.Val277Met) were deleterious, consistent with markedly reduced A-transferase activity. This case highlights the value of genotyping and in silico prediction in identifying the causative allele and clarifying ABO discrepancies.

In December 2025， the American Association for the Study of Liver Diseases （AASLD） and the American Society of Transplantation （AST） jointly issued an updated guideline on the evaluation of adult liver transplant candidates. The guideline is organized into four domains， i.e.， referral for liver transplantation， candidate evaluation， contraindications to liver transplantation， and special considerations （e.g.， living donor liver transplantation）， in order to provide a standardized framework for clinical assessment. This new guideline updates the 2013 edition based on the latest evidence-based medical evidence and incorporates discussions on emerging indications for liver transplantation， including intrahepatic cholangiocarcinoma and colorectal liver metastases. This guideline emphasizes that candidate assessment must be individualized， and the assessment process must be transparent and consistent. This article gives an excerpt of the key recommendations in this guideline for readers’ reference.

In order to investigate the related pathogens and reveal the etiological characteristics of gout in goslings,191 typical clinical cases from partial regions of China were examined by RT-PCR/PCR detection of viral nucleic acids in domestic poultry and pathological analysis.The autop-sy results show that the clinical cases could be classified into three types based on the severity of urate deposition:severe,moderate,and mild,namely systemic urate deposition,local urate deposi-tion mainly in the liver and kidneys,and only a small amount of fine-grained urate deposition in the liver,gallbladder,or glandular stomach.The results of RT-PCR/PCR detection showed that the to-tal positive rates were as follows:GAstV Group2 63.9％,GAstV Group1 50.3％,AAstV-2 38.7％,novel Muscovy duck parvovirus(NPV)17.8％,GPV 16.2％,GoCV 12.6％,MDPV 7.9％,MDRV 8.4％,DPV 0.5％,GPMV and NDV 0.5％,the AstV-1、ARV、TMUV、NDV、FAdV、GHPyV were zero.Among all the postive samples,the rates of single positive,double positive,and multiple posi-tive were 18.3％,27.2％,and 44.0％,respectively.The rate of single positive samples containing AAstV was only 12.0％,the double or multiple positive samples containing GAstV Group 1/2 was 60.7％,and the rate of samples without GAstV Group 1/2 was 10.5％.The results also showed that 20(10.5％)samples were negative for 16 types of viruses.The AAstV particles isolated from single positive samples appear spherical shape,non-enveloped and 20-80 nm minsize.Two types of virus particles which with spherical shape and diameters of 40-100 and 20-40 nm can be isolated from the negative samples.The virus inoculation results show that the goose embryos can be led to death by clinical GAstV isolates,which with classic histopathological characteristics.Although the GAstV isolates cannot led to death and obvious typical histopathological change in goslings,the vi-ral nucleic acids can be detected in heart,liver,spleen,kidney,intestine and cloacal anal swabs.The above results indicated that there were multiple pathogens co-infection dominated by AAstv in Gosling gout in China,including cross species infections of multiple AAstVs,parvovirus,ARV and suspec-ted novel viruses.Moreover,the GAstV maybe not the only pathogen causing gout in goslings.

A significant portion of newly diagnosed lung cancer cases occurs in populations exposed to air pollution. The World Health Organization has identified air pollution as a human carcinogen, prompting many countries to implement monitoring systems for ambient particulate matter (PM). PM is composed of a complex mixture of organic and inorganic particles, both solid and liquid, that are found in the air. Given the carcinogenic properties of PM and the high prevalence of lung cancer among exposed populations, exploring their connection and clinical implications is critical for effectively preventing lung cancer in this group. This review explores the relationship between ambient PM and lung cancer. Epidemiological studies have demonstrated a dose-response relationship between PM exposure and lung cancer risk. PM exposure induces oxidative stress, disrupts the body’s redox balance, and causes DNA damage, which is a crucial factor in cancer development. Recent findings on the strong correlation between ambient PM and adenocarcinoma highlight the importance of understanding the specific molecular and pathological mechanisms underlying pollution-related lung cancer. In addition to efforts to control emission sources at the international level, a more individualized approach is essential for preventing PM-related lung cancer.

Objective: We aimed to elucidate the metabolic function and phenotype of AK5, a gene with an unknown function in metabolism. Methods: We generated AK5 knockout (KO) mice and administered high-fat and fasting diets to the mice to confirm their physiological phenotype and metabolic differences. Results: In the high-fat diet (HFD) test, no differences in body weight, epididymal white adipose tissue (eWAT), or fat mass of AK5 KO mice were observed. In indirect calorimetry, the respiratory exchange ratio and activity counts increased in normal chow diet mice, but there was no difference between the HFD groups. At the mRNA level, there were no significant differences in the expression of lipid metabolism markers between wild-type and AK5 KO mice. Still, the glucose signal of adipocytes increased in AK5 KO mice. In the fasting test, the eWAT of AK5 KO mice was significantly reduced, as was the expression of lipid metabolism and inflammation-related immune markers. Thus, the apoptosis of adipocytes increased, and an imbalance in energy metabolism occurred. Conclusions and Relevance: When AK5 KO mice are energy deficient, it becomes difficult to use eWAT for energy storage, imbalance occurs, and apoptosis of adipocytes in eWAT increases.
