The incidence and mortality of hepatocellular carcinoma (HCC) in China are among the highest in the world, imposing a heavy social burden. Liver resection and liver transplantation are the primary radical treatments for HCC, although most patients are no longer able to meet the surgical requirements at initial diagnosis. Yttrium-90 microsphere selective internal radiation therapy (⁹⁰Y-SIRT) has the advantages of shrinking tumors, enlarging residual liver, regressing portal vein tumor thrombus and improving the quality of life, which can be used for conversion, downstaging and bridging therapy for HCC before surgical treatment, enabling patients regain the chance of radical treatment and reducing the postoperative recurrence rate. This review focuses on the clinical application and progress of ⁹⁰Y-SIRT in this field.

To improve the understanding of clinicians on the diagnostic criteria and treatment principlis of pulmonary alveolar proteinosis(PAP),which is a rare respiratory disease.European Respiratory Society published the first edition guidelines for PAP,including a systematic review of the literature and the application of the grading of recommendations,assessment,development and evaluation(GRADE)approach to assess the certainty of evidence and the strength of recommendations.Five questions of patient,intervention,comparison,outcome(PICO)and two narrative questions were developed.Recommendations and evidence-based evidence were given,including management of PAP,whole lung lavage,granulocyte-macrophage colony-stimulating factor(GM-CSF)therapy,rituximab,plasma exchange,and lung transplantation.In addition,recommendations were given for the use of GM-CSF antibody testing,bronchoalveolar lavage,and lung biopsy.This study is to interpret the main content of the guideline.

Herein we review the contribution of WHO to promote the construction and development of the global haemovigilance system, the ethical principles of donor safety of the

Multiple sclerosis (MS) is a neuroinflammatory demyelinating disease, mediated by pathogenic T helper 17 (Th17) cells. However, the therapeutic effect is accompanied by the fluctuation of the proportion and function of Th17 cells, which prompted us to find the key regulator of Th17 differentiation in MS. Here, we demonstrated that the triggering receptor expressed on myeloid cells 2 (TREM-2), a modulator of pattern recognition receptors on innate immune cells, was highly expressed on pathogenic CD4-positive T lymphocyte (CD4⁺ T) cells in both patients with MS and experimental autoimmune encephalomyelitis (EAE) mouse models. Conditional knockout of Trem-2 in CD4⁺ T cells significantly alleviated the disease activity and reduced Th17 cell infiltration, activation, differentiation, and inflammatory cytokine production and secretion in EAE mice. Furthermore, with Trem-2 knockout in vivo experiments and in vitro inhibitor assays, the TREM-2/zeta-chain associated protein kinase 70 (ZAP70)/signal transducer and activator of transcription 3 (STAT3) signal axis was essential for Th17 activation and differentiation in EAE progression. In conclusion, TREM-2 is a key regulator of pathogenic Th17 in EAE mice, and this sheds new light on the potential of this therapeutic target for MS.

Children and adults differ significantly in physiology,biochemistry and immune function,which leads to sig-nificant differences in blood transfusion strategies between children and adults.To guide the clinical transfusion practice of pediatric patients and improve the prognosis of children,the National Health Commission organized the formulation and re-lease of the health industry standard Guideline for Pediatric Transfusion(WS/T 795-2022).This paper will briefly introduce some concepts that help understand of the Standard and the preparation process of the Standard,and explain and interpret the preparation of the"scope","general provisions"and"factors to consider"of the Standard,hoping to contribute to the understanding and implementation of the Standard.

Objective To investigate the relationship between factors related to the transforming growth factor β(TGF-β)/Aerine-threonine kinase receptors(Smads)signaling pathway and cognitive dysfunction in peripheral blood of patients with aneurysmal subarachnoid hemorrhage(aSAH).Methods The clinical data of 100 patients with aSAH admitted to Chongzuo City People's Hospital from October 2018 to March 2022 were retrospectively selected and grouped according to the patients'Montreal Cognitive Assessment Scale(MoCA)scores,including 54 cases with cognitive dysfunction and 46 cases without cognitive dysfunction.The clinical data,peripheral blood TGF-β,Smad1,Smad3,and Smad7 mRNA expression levels of the two groups were compared.The relationship between pathway-related factors and cognitive dysfunction in patients with aSAH was analyzed in a multifactorial manner.The predictive value of pathway-related factors for cognitive dysfunction in aSAH patients was assessed using the receiver operating characteristic(ROC)curve.Results Peripheral blood TGF-β,Smad1,Smad3,and Smad7 mRNA expression levels were higher in the cognitively impaired group than in the group without cognitive impairment(P<0.05).Multifactorial showed that pathway-related factors were significantly associated with cognitive impairment in patients with aSAH(P<0.05).The ROC showed that the area under the curve(AUC)of pathway-related factors jointly predicted cognitive dysfunction in patients with aSAH was superior to that predicted alone(P<0.05).Conclusion The high expression of factors related to the TGF-β/Smads signaling pathway in the peripheral blood of aSAH patients suggests that this pathway may be associated with cognitive dysfunction in patients.

Objective:To investigate the clinical efficacy and safety of transarterial chemoembolization (TACE) combined with lenvatinib plus PD-1 inhibitor (TACE+Len+PD-1) versus TACE combined with lenvatinib (TACE+Len) for patients with unresectable intermediate-advanced hepatocellular carcinoma (HCC).Methods:The data of 94 patients with intermediate-advanced HCC who received TACE+Len+PD-1 (One week after TACE, the patient were treated with lenvatinib and PD-1 inhibitor. lenvatinib, 8 or 12 mg/d, orally; PD-1 inhibitor, 200 mg/3 weeks, iv) or TACE+Len (One week after TACE, the patient were treated with lenvatinib.lenvatinib, 8 or 12 mg/d, orally) in the Second Affiliated Hospital of Guangzhou Medical University from June 2019 to February 2021 were collected and retrospectively analyzed. Among these patients, 44 were in the TACE+Len+PD-1 group and 50 were in the TACE+Len group. Tumor responses were evaluated according to modified response evaluation criteria in solid tumors. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and adverse events (AEs) were compared between the two groups. The potential prognostic factors for PFS and OS were determined.Results:The ORR of TACE+Len+PD-1 group and TACE+Len group was 72.8% (32/44) and 52.0% (26/50) (χ2=4.25, P=0.039), respectively. The DCR of TACE+Len+PD-1 group and TACE+Len group was 86.4% (38/44) and 62.0% (31/50) (χ2=7.12, P=0.008), respectively. The median PFS and median OS in TACE+Len+PD-1 group were significantly longer than those in TACE+Len group (PFS, 7.9 vs. 5.6 months, χ2=7.91, P=0.005; OS, 18.5 vs. 13.6 months, χ2=4.40, P=0.036). Multivariate Cox regression analyses showed that TACE+Len (HR=2.184,95%CI 1.366-3.493), incomplete tumor capsule (HR=2.002,95%CI 1.294-3.209) and extrahepatic metastasis (HR=1.765,95%CI 1.095-2.844) were the independent risk factors for PFS, while TACE+Len (HR=2.081,95%CI 1.097-3.948) and BCLC stage C (HR=7.325,95%CI 2.260-23.746) were the independent risk factors for OS. The incidence of ≥grade 3 AEs in TACE+Len+PD-1 group was similar to that in TACE+Len group (χ2=0.45, P=0.501). Conclusion:Compared with TACE+Len, TACE+Len+PD-1 resulted in a better tumor response and a longer PFS and OS in patients with intermediate-advanced HCC.

Objective:To explore the rule of point selection and compatibility of auricular acupressure for climacteric syndrome based on data mining, so as to provide a reference for auricular acupressure for climacteric syndrome patients with different syndrome differentiation types.Methods:The article on auricular acupressure for climacteric syndrome was retrieved through computer in PubMed, Web of Science, China National Knowledge Infrastructure, WanFang Data and China Biomedical Literature Database. The retrieval time limit was from the establishment of the database to February 27, 2022. The database of auricular points for the treatment of climacteric syndrome with auricular acupressure was established using Excel. SPSS 25.0 was used to conduct frequency on auricular points in the database. The association rules were analyzed by SPSS Modeler 18.0 to describe the compatibility and association rules among auricular points.Results:A total of 145 articles were finally included. The main syndrome types of climacteric syndrome were deficiency syndrome, including kidney-yin deficiency syndrome, liver kidney-yin deficiency syndrome and kidney-yang deficiency syndrome. There were 63 auricular points involved in the treatment of climacteric syndrome with auricular acupressure. Most of the auricular points were distributed in the auricular concha. The most commonly used auricular points were kidney, endocrine, liver, and shenmen. The commonly used compatible auricular points for the treatment of climacteric syndrome with auricular acupressure were internal genitalia-endocrine-sympathy, liver-endocrine-kidney-shenmen, internal genitalia-endocrine-subcortex-sympathy-kidney.Conclusions:Data mining can effectively analyze the main syndrome types of climacteric syndrome, the commonly used auricular points and their compatibility rules in the treatment of climacteric syndrome with auricular acupressure, and can provide reliable basis for clinical nurses to select points.

Objective:To study the use of radioactive I-125 seed implantation in the treatment of transarterial chemoembolization (TACE)-refractory hepatocellular carcinoma (HCC).Methods:A retrospective study was conducted on 70 patients with HCC who were initially treated with TACE between July 1, 2016 and August 31, 2019 at the Second Affiliated Hospital of Guangzhou Medical University. After these patients were found to be refractory to TACE, 29 patients were converted to radioactive I-125 seed implantation (the 125I seed group), and 41 patients were continued with TACE (the TACE group). The objective response rate, progression-free survival (PFS), overall survival (OS), total overall survival (TOS) of the two groups were compared. Results:There were 59 males and 11 females, aged (60.5±11.9 ) years in this study. At 1, 3, 6 months after treatment, the objective response rates of the 125I seed group were 20.7%, 40.7%, 34.6%, respectively, which were significantly higher than that of the TACE group of 2.6%, 3.3%, 5.0%, respectively. The PFS, OS, TOS in the 125I seed group were 7.6, 21.1, 32.1 months, respectively, which were significantly better when compared with the TACE group (3.5, 8.5, 14.8 months, respectively, all P<0.05). There was no significant difference in the embolization syndrome between the two groups [93.1%(27/29) vs 100.0%(41/41), P>0.05]. Child-Pugh B grading ( HR=0.311, 95% CI: 0.160-0.603, P=0.005) and TACE ( HR=0.308, 95% CI: 0.159-0.597, P=0.002) were independent risk prognostic factors for survival. Conclusion:This study showed better treatment efficacy and safety using radioactive I-125 seed implantation in TACE-refractory HCC and this treatment significantly improved survival of patients when compared with TACE alone.

Objective:To evaluate the efficacy and safety of anti-programmed cell death 1 (PD-1) receptor monoclonal antibody (MoAb) in patients with advanced hepatocellular carcinoma (HCC) after treatment of transcatheter arterial chemoembolization (TACE) combined with tyrosine kinase inhibitor (TKI).Methods:From February 2019 to February 2020, 56 HCC patients who relapsed after TACE-TKI treatment in Department of Interventional Radiology, The Second Affiliated Hospital of Guangzhou Medical University were enrolled. All patients received anti-PD-1 MoAb (sintilimab injection) and followed up every 6 weeks. According to mRECIST, the curative effect was evaluated as complete response (CR), partial response (PR), stable disease (SD) or progressive disease (PD). Objective response rate (ORR) and disease control rate (DCR), progression-free survival (PFS) and treatment-related adverse events (TRAEs) were recorded. Univariate analysis by Chi-square test and binary logistic regression model was used to determine the influencing factors of DCR. The Kaplan-Meier method and Cox proportional hazard regression model were used to analyze the survival data.Results:A total of 48 patients were enrolled in this study including 42 males and 6 females, with a median age of 55 years (29-71 years). ECOG scores comprised of 0 in 24 cases, 1-2 in 24 cases. Thirty-six patients were in Child-Pugh grade A of liver function and 12 cases were grade B. The median follow-up time was 4.5 months. There were 2 patients achieved CR, 12 patients with PR and 16 with SD. ORR was 29.2%, DCR was 62.5%. The independent influencing factors of DCR was ECOG score and AFP level ( P=0.031, P=0.012). Median PFS was 4.1 months (95% CI 2.7-5.4 months), and ECOG score was the independent influencing factor of PFS ( P=0.042). Treatment-related adverse events were reported in 70.8% (34/48) patients. Incidence of grade Ⅲ-Ⅳ TRAEs was 22.9% (11/48). Conclusion:In patients with HCC who relapse from TACE and TKI treatment, anti-PD-1 monoclonal antibody is efficacious safe especially in those with ECOG 0 score.
