Objective To explore the safety of Yttrium-90 resin microsphere selective internal radiation therapy (90Y-SIRT) on malignant liver tumors. Methods A retrospective analysis was conducted on 64 patients with malignant liver tumors who underwent 90Y-SIRT from February 2023 to November 2024 at Weifang People’s Hospital. The clinical characteristics of the patients and the occurrence of adverse reactions after treatment were analyzed to assess the safety of 90Y-SIRT. Results Among the 64 patients, there were 52 males (81.25%) and 12 females (18.75%); the average age was (56.29±11.08) years. Seven patients (10.94%) had tumors with maximum diameter of less than 5 cm, 38 patients (59.38%) had tumors with maximum diameter of 5-10 cm, and 19 patients (29.68%) had tumors with maximum diameter of greater than 10 cm. There were 47 cases (73.44%) of solitary lesions and 17 cases (26.56%) of multiple lesions; 53 cases (82.81%) were primary liver cancers and 11 cases (17.19%) were metastatic liver cancers. Of the 64 patients, 63 successfully completed the Technetium-99m macroaggregated albumin (99mTc-MAA) perfusion test and received the 90Y-SIRT; one patient received 90Y-SIRT after the second 99mTc-MAA perfusion test due to a work error. The most common adverse reactions included grade 1 alanine aminotransferase (ALT) elevation in 26 cases (40.62%) and grade 2 in 2 cases (9.37%), grade 1 aspartate aminotransferase (AST) elevation in 27 cases (42.18%) and grade 2 in 7 cases (10.93%); grade 1 nausea in 17 cases (26.56%) and grade 2 in 6 cases (9.37%); grade 1 abdominal pain in 12 cases (18.75%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%); grade 1 vomiting in 11 cases (17.18%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%). Conclusion The adverse reactions of 90Y-SIRT for treating malignant liver tumors are mild, indicating good safety.

Corneal lymphangiogenesis plays a crucial role in ocular diseases. Normally, the cornea lacks blood vessels and lymph vessels, which are essential for maintaining transparency and function of cornea. However, certain diseases or injuries will prompt angiogenesis and lymphangiogenesis in cornea, thus disrupting the structure and function of cornea. Although various drugs targeting corneal angiogenesis have been applied in clinical practice, there is still a gap in medications targeting corneal lymphangiogenesis. Therefore, this review will introduce the factors related to corneal lymphangiogenesis, introduce related ocular diseases, and analyze the current treatment status, which will provide more options and possibilities for the treatment of lymphangiogenesis in ocular diseases and provide guidance for future research and drug development.

ObjectiveTo prepare a rat model of heart failure after myocardial infarction by ligation of the anterior descending branch of the left coronary artery, and to observe the effect of Shenfu Yixin granules on the mitochondrial dynamics of rats with heart failure. MethodFifty SD male rats were randomly taken ten as the sham operation group and the rest as modeling group. The rat model of heart failure after myocardial infarction was prepared by ligation of anterior descending branch of left coronary artery. According to the left ventricular ejection fraction(LVEF) on the 28th day after operation, the model rats were randomly divided into the model group, Shenfu Yixin granule low-dose and high-dose groups(3.011, 15.055 g·kg-1) and sacubitril valsartan sodium group(20.83 mg·kg-1). Each administration group was gavaged daily with the corresponding dose of drug solution, while the sham operation group and model group were given the same amount of normal saline once a day for 28 days, with 6 rats in each group. Ultrasound was used to detect the cardiac function parameters, rat heart mass and body mass were weighed to calculate the cardiac mass index, enzyme linked immunosorbent assay(ELISA) was used to detect serum brain natriuretic peptide(BNP) and soluble growth stimulation expressed gene 2 protein(sST2) levels. Hematoxylin-eosin(HE) staining was used to observe the pathological morphology of the myocardium. Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) and Western blot were used to detect the mRNA and protein expression of mitochondrial fusion protein 1/2(Mfn1/2), optic atrophy protein 1(Opa1), dynamin-related protein 1(Drp1) and fission protein 1(Fis1). ResultCompared with the sham operation group, the mRNA and protein expression of LVEF, Mfn1, Mfn2, Opal in the model group decreased(P<0.05), while BNP, sST2, cardiac mass index, Drp1, Fis1 mRNA and protein levels increased(P<0.05). Compared with the model group, the expression of LVEF, Mfn1, Mfn2, Opal mRNA and protein increased in Shenfu Yixin granule high-dose and sacubitril valsartan sodium groups(P<0.05), while BNP, sST2, cardiac mass index, Drp1, Fis1 mRNA and protein levels decreased(P<0.05). Pathological observation showed that compared with the sham operation group, the model group had disordered arrangement of myocardial cells, inflammatory cell infiltration and myocardial fibrosis. Compared with the model group, the degree of inflammatory cell infiltration, myocardial or interstitial fibrosis was improved and alleviated in all administered groups. ConclusionShenfu Yixin granules can resist heart failure, reduce cardiac mass index, decrease BNP and sST2 contents, and improve cardiac function. Its mechanism may be related to the adjustment of mitochondrial dynamics.

Spinal muscular atrophy(SMA)is a rare genetic neuromuscular disease characterized by significant clinical heterogeneity among patients.According to the severity and progression rate of the condition,the disease is classified into five types.In recent years,because of the promotion of multidisciplinary manage-ment and the application of disease-modifying therapies,the prognosis of SMA patients has significantly im-proved,resulting in more patients entering into the stage of adolescence and adulthood.The varying conditions of different types of patients in the adolescence and adulthood make the manifestations more complex and diverse,leading to the difficulty in identification and diagnosis.Because of the vast territory and large popula-tion in China,coupled with uneven health care development among different regions of the country,the diagno-sis and treatment for adolescent and adult SMA patients are very challenging.Misdiagnosis or delayed diagnosis remains a primary unresolved issue for many patients.The fact that patients have to visit various departments in their initial consultation highlights the importance of enhancing the recognition of high-risk adolescent and adult SMA populations among the non-neuromuscular specialists.This article attempts to explore a simple,clear,and highly operational"portrait"way of identifying the high-risk adolescent and adult SMA patients in the popula-tion,aiming at assisting the non-neuromuscular specialists to diagnose SMA patients in a way of early recogni-tion and diagnosis and to ensure patients receiving standardized treatment as early as possible.The ultimate goal is for the higher clinical gain and a better life for patients and their families.

Autoimmune paranodopathy (APN) has emerged as an independent rare disease,which is medicated by autoimmune antibodies against the essential complex of paranodal region of Ranvier. The antibodies include anti-neurofascin 155 antibody, anti-contactin-1 antibody and anti-contactin-associated protein 1 antibody. Although there are many similarities between APN and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), patients with APN have relatively unique clinical features, pathogenesis, histopathological results and responses to intravenous immune globulin, distinguishing from typical CIDP. The predominant subclass of IgG among pathogenic antibodies is IgG4, meanwhile, other subclasses have been rarely reported. Early detecting the APN related antibodies and their subclasses not only helps to clarify the diagnosis, but also provides valuable clinical information for the selection of precise treatment and prognosis.

OBJECTIVE To investigate the relationship between metformin and sarcopenia-related traits. METHODS Based on the data from publicly genome-wide association study-related databases, using single nucleotide polymorphisms strongly associated with metformin as instrumental variables, the two-sample Mendelian randomization (MR) analysis methods [inverse variance weighting (IVW) method, MR-Egger regression method and weighted median estimator method] were employed to investigate the relationship between metformin and three sarcopenia-related traits (low grip strength, muscle mass and walking speed). Cochran’s Q test was used to assess heterogeneity, MR-Egger intercept test was used to detect horizontal pleiotropy, and leave-one-out analysis was performed for sensitivity analysis. RESULTS The results of IVW method showed that metformin use was significantly associated with an increased risk of low grip strength (β=1.550, 95%CI was 0.389-2.711, P=0.009) and reduced limb muscle mass (right leg lean body mass: β=-0.665, 95%CI was -1.018--0.312, P<0.001; left leg lean body mass: β=-0.710, 95%CI was -1.049--0.371,P<0.001; right arm lean body mass: β=-0.471, 95%CI was -0.890--0.053, P=0.027; left arm lean body mass: β=-0.463, 95%CI was -0.865--0.061, P=0.024),but was not associated with walking speed. The results or causal effects of the other two methods are consistent with it. The Cochran’s Q test indicated some degree of heterogeneity in the result of this study. No horizontal pleiotropy was detected by the MR-Egger intercept test. The sensitivity analysis suggested that the results of this study were stable. CONCLUSIONS Metformin may increase the risk of sarcopenia.

Under the “patient-centered” drug regulation concept, the inclusion of patient dimensions in real-world evidence becomes increasingly important. Patient experience data can complement and interpret existing data, generate evidence directly from patients, and achieve patient participation in drug development. Data types include patient-reported outcomes and free-text data, which can be collected autonomously or obtained from databases. Application scenarios involve new drug registration, safety evaluation, and additional indications. In China, applying patient experience data to real-world study mainly faces the following challenges: lack of conditions, standards, and motivation to collect high-quality data, a single type of data, and the difficulty of balancing data security with freedom, etc. It is recommended to issue special guidelines, establish a measurement tool certification process, expand data collection channels, explore data source integration methods, optimize the informed consent mechanism, and establish an evidence synergy mechanism to promote the practical application of the “patient-centered” concept in real-world study of drugs.
