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.

Objective To investigate the effect of tissue-resident memory T cells(TRM)on imiquimod-induced psoriatic-like skin lesions in mice,and to elucidate the underlying mechanisms of TRM involvement in this process.Methods Forty female BALB/c mice were procured and randomly allocated into four groups:ten in the blank control group,and thirty for the establishment of a psoriasis mouse model.Following successful modeling,the thirty mice were further randomized into three groups:the model control group,the methotrexate-treated group,and the imiquimod-treated group,with ten mice in each group.Mice in the blank control group and model control group were uniformly treated with Vaseline for intervention.The methotrexate group and the imiquimod group were treated with 62.5mg of 5％imiquimod cream.The methotrexate group was administered by gavage at a dose of 1 mg/kg,and the gavage volume of each group was 10 mL/kg.The model control group,blank group and imiquimod group were gavaged with the same volume of normal saline.Treatment was conducted over six consecutive days.Subsequently,comparisons were made across groups regarding the psoriasis area and severity index(PASI),histopathological findings,inflammatory cytokine levels,and TRM cell levels.Results(1)The imiquimod group exhibited signifi-cantly lower scores for erythema(2.54±0.32),skin thickening(2.59±0.25),and scaling(2.52±0.29)compared to the methotrexate group,model control group,and blank control group(P<0.05).Additionally,the methotrexate group demonstrated reduced scores for erythema,skin thickening,and scaling compared to the model control group(P<0.05).(2)Hematoxylin-eosin(HE)staining revealed that the epidermis in the methotrexate group became thin-ner,with fewer parakeratotic cells and increased hair follicles.Conversely,the imiquimod group displayed abnor-mal cell morphology and relatively thicker white skin after modeling.(3)The imiquimod group showed significantly lower levels of TNF-α(51.63±4.39 pg/mL),IL-1β(35.53±4.15 pg/mL),IFN-γ(23.43±3.41 pg/mL),and IL-23(15.24±2.95 pg/mL)compared to the methotrexate and model control groups(P<0.05).Similarly,the methotrexate group exhibited reduced levels of TNF-α,IL-1β,IFN-γ,and IL-23 compared to the model control group(P<0.05).(4)The imiquimod group had significantly lower levels of CD8+CD103+cells(15.39±2.31)than the methotrexate and model control groups(P<0.05).Furthermore,the methotrexate group demonstrated lower levels of CD8+CD103+cells compared to the model control group(P<0.05).Conclusion Miquimod induces heavier skin lesions,faster response,and more epidermal thickening in psoriasis like mice.CD8+CD103+TRM cells and inflammatory factors may be involved in the recurrence of psoriasis.

Objective:To explore the hematological phenotype and genotypic characteristics of five Chinese individuals with a rare thalassemia mutation HBB: c. 93-21G>A. Methods:A retrospective study was carried out on five individuals identified by the People′s Hospital of Yangjiang and Guangzhou Hybribio Co., Ltd. from May 2018 to September 2022. Routine blood test and hemoglobin electrophoresis were performed, and the genotypes of five subjects were determined by using PCR combined with reverse dot blotting (RDB), nested PCR, Gap-PCR and Sanger sequencing. This study was approved by Medical Ethics Cornmittee of the People′s Hospital of Yangjiang (Ethics No. 20240001).Results:Among the five individuals, hematological data of one was unavailable, and the remaining four had presented with microcytosis and hypochromia. The results of hemoglobin electrophoresis indicated that all of them had a HbA 2 level of ≥4.7%. Genetic analysis showed that one case had harbored compound heterozygous mutations of ααα anti3.7 triplet and HBB: c. 93-21G>A, one had compound heterozygous mutations of -α 3.7 and HBB: c. 93-21G>A, whilst the remaining three were heterozygous for the HBB: c. 93-21G>A mutation. Conclusion:The hematological phenotype of β-thalassemia carriers ( HBB: c. 93-21G>A) is similar to that of other β + thalassemia heterozygotes with mild β-thalassemia characteristics.

OBJECTIVE: To assess the association of Eph-receptor tyrosinekinase-type A2 (EphA2) gene polymorphisms with susceptibility to age-related cataract (ARC) among ethnic Han Chinese from Hubei Province. METHODS: 280 patients with cortical ARC and 200 healthy controls were recruited. Polymorphisms at four loci (rs3768293, rs3754334, rs477558 and rs7548209) of the EphA2 gene were detected by PCR-restriction fragment length polymorphism (PCR-RELP) assay. Allelic and genotypic frequencies of the two groups were compared. RESULTS: Compared with the control group, the AA genotype of rs3768293 locus was more common, while the AC genotype was much rarer (P< 0.05). No significant difference was found in allelic and genotypic frequencies of rs3754334 locus between the two groups (P> 0.05). The AA genotype of the rs477558 locus was more common in the patient group, while the AG genotype was much rarer (P< 0.05). The genotype GG of the rs7548209 locus was more common in the patient group, while the CG genotype was rarer (P< 0.05), though no significant difference in allelic or haplotypic frequencies between the two groups (P> 0.05). CONCLUSION Polymorphisms of rs477558, rs7548209 and rs3768293 loci of the EphA2 gene are associated with susceptibility to ARC among ethnic Han Chinese from Hubei province.

Objective To investigate the expression levels of serum miR-210and miR-375in patients with non-small cell lung cancer (NSCLC).Methods A total of 25NSCLC patients (NSCLC group) and 14healthy volunteers (control group) were enrolled in this study.The relative expression levels of 9miRNAs (miR-182, miR-126, miR-31, miR-21, miR-221, miR-200b, miR-183, miR-210and miR-375) in 6 NSCLC patients and 6healthy volunteers were measured by RT-qPCR.The dysregulated miRNAs will be selected as candidate miR-NAs.The diagnostic value were evaluated by ROC curve.Results Compared with control group, 2 (miR-210and miR-375) out of 9miRNAs were up-regulated in NSCLC group, and the differences were statistically significant (P＜0.05), while the other 7miRNAs were not consistent with the reported literatures.Therefore, miR-210and miR-375were selected as candidate miRNAs.We found that the relative expression level of miR-210in the lung adenocarcinoma group was significantly different from control group (P＜0.05), while there was no significant difference between the squamous cell carcinoma group and the control group (P＞0.05).There was no significantly statistical difference in the relative expression level of miR-375between lung squamous cell carcinoma group, lung adenocarcinoma group and the control group (P＞0.05).The AUC of serum miR-210of lung adenocarcinoma group was 0.737 5 (95％CI:0.498 3-0.976 7, P=0.091 4) with a medium diagnostic value.Conclusion MiR-210is highly expressed in the serum of patients with lung adenocarcinoma, suggesting that miR-210may be a novel tumor marker for the diagnosis of lung adenocarcinoma.The value of miR-375in the diagnosis of lung cancer still needs to be further explored.

Objective To explore the influence of telephone follow-up after discharge on the re-admission rate of patients with chronic heart failure.Methods In total,161 patients were randomly divided into the observation(n=81)and control group (n=80).All participants received conventional guidance following discharge from our hospital.The patients in the observation group were subject to telephone follow-up for 6 months and individualized caring intervention.The re-admission rates after 6 months after discharge between two groups were statistically compared.Result The re-admission rate in the observation group was 30.9%, significantly lower compared with 42.5% in the control group(P<0.05).Conclusion The telephone follow-up combined with individualized caring intervention can reduce the re-admission rate among the patients with chronic heart failure.

Objective To compare the effects of two positions in the infant megacolon radical operation.Methods Sixty infants undergoing abdominal perineal megacolon radical operation were randomly divided into the control group and the observation group in equal number.The former took the traditional lithotomy position and the latter modified suspended lithotomy position.Results The operative exposures in the observation group were much more sufficient than that of the control group(P<0.05).While adverse skin reactions in the observation group were more uncommon than those of the control group(P<0.05).Conclusion The suspended lithotomy position may provide a better exposure and result in fewer adverse skin reactions during the abdominal perineal megacolon radical operation.

ObjectiveTo study the risk factors for children with incomplete Kawasaki disease(IKD) to decrease the development of coronary artery lesions (CAL).MethodsAll children diagnosed as IKD from Jan.2005 to Apr.2011 in our department were reviewed retrospectively for their clinical data,laboratory values and treatment measures.ResultsEight of the children (8/36,22.2％ ) were positive for CAL.The count of white blood cell( WBC),count of platelet(PLT),hematocrit and C reactive protein(CRP) level were ( 18.36 ± 4.63) × 109/L,(450.30 ± 155.40) × 109/L,( 25.63 ± 3.53 ),( 18.30 ± 3.80) mg/L and ( 13.48 ±3.27) × 109/L,(350.60 ± 56.80) × 109/L,( 33.78 ± 2.24 ),(9.70 ± 2.50) mg/L in the CAL group and non-CAL group respectively.And there were significant differences on the four indexes between CAL group and non-CAL group ( t =2.58,2.65,2.73,2.48,respectively,P ＜ 0.05 ).Pyretolysis time of children first undergoing globulin treatment was (2.5 ± 1.5 ) d and ( 1.5 ± 1.0 ) d in children under 1-year old and those above l-year old respectively,and the difference was significant ( t =2.35,P ＜ 0.05).ConclusionCAL should be cautiously prevented in IKD infants under l-year old with a fever lasting for over 5 days,decreased hematocrit and elevated WBC count,PLT count,Hct and CRP.Infant IKD patients are not so sensitive to intravenous gamma globulin and tend to occur CAL.They should be given an early diagnosis and timely treatment.
