In July 2024， the European Association for the Study of the Liver released the latest edition of EASL Clinical Practice Guidelines on liver transplantation. The purpose of the EASL guidelines presented here is not to cover all aspects of liver transplantation， but to focus on important advances since the release of the 2016 edition of EASL guidelines. This article gives an excerpt of the recommendations in the guidelines.

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.

OBJECTIVE: To evaluate the clinical effect of "Tongdu Yisui" (unblocking the governor vessel and benefiting marrow) acupuncture and moxibustion on Meige syndrome. METHODS: Fifteen patients with Meige syndrome were treated with "Tongdu Yisui" acupuncture and moxibustion. Acupuncture was applied to Baihui (GV20), Dazhui (GV14), Shenzhu (GV12), Zhiyang (GV9), Jinsuo (GV8), bilateral Taixi (KI3), Zhaohai (KI6) and etc. Moxibustion was delivered at Jinsuo (GV8). After acupuncture and moxibustion at these body points, Jiao's scalp acupuncture was operated at bilateral chorea-tremor control area, and the patients were asked to walk for 20 min during needle retaining. Acupuncture and moxibustion were administered 20 min each time, once every two days, 3 times weekly and for 8 consecutive weeks. Assessments were conducted before treatment, after treatment, and follow-up at three months after treatment completion using the Burke-Fahn-Marsden dystonia rating scale (BFMDRS-M), abnormal involuntary movement scale (AIMS), and blepharospasm disability index (BSDI); and the clinical effect was evaluated after treatment. RESULTS: Compared before treatment, the scores of the sub-items of BFMDRS-M for eyes, mouth, speech and swallowing, and neck, as well as the total score of the scale, AIMS score and BSDI score decreased after treatment and during follow-up (P<0.05); the scores of the above indexes were not different statistically in comparison between the follow-up and after treatment (P>0.05). After treatment, 13 cases were effective, 2 cases were failed and the total effective rate was 86.7% (13/15). CONCLUSION "Tongdu Yisui" acupuncture and moxibustion can effectively alleviate motor symptoms and dysfunction of Meige syndrome and presents the sustained therapeutic effect.

Elastofibroma is a rare soft tissue tumor that most commonly occurs in the subscapular region. It has also been reported in several other anatomical locations. To our knowledge, no previous reports have described elastofibromas in the anterior aspect of the face. A 36-year-old man with intellectual disability was referred to our department for the evaluation of a painless multinodular lesion on the philtrum. The lesion was initially misdiagnosed as a dermatologic condition by the department of dermatology and was treated accordingly, however, it worsened, prompting referral to our department. We performed a surgical excision of the lesion and reconstructed the resulting skin defect with a skin graft. Histopathological examination confirmed the diagnosis of elastofibroma. This case underscores the importance of including elastofibroma in the differential diagnosis of facial neoplasms, particularly when the presentation is phymatous.
