Objective To explore the effect of different needle track management on Yttrium-90 microsphere selective internal radiation therapy (⁹⁰Y-SIRT) on liver cancer after liver biopsy. Methods A retrospective analysis was conducted on the clinical data of 21 patients with liver cancer who underwent Technetium-99m-macroaggregated albumin (^99mTc-MAA) evaluation and ⁹⁰Y-SIRT after liver biopsy from June 2023 to December 2024. The methods of needle track management, hepatic arteriovenous shunting, and lung shunt fraction (LSF) were recorded. The occurrence of hepatic arteriovenous fistula (HAVF), as well as the corresponding countermeasures were analyzed. Results Among the 21 liver cancer patients, 7 cases (medical glue group) underwent embolization of the needle tract with medical glue (N-butyl 2-cyanoacrylate [NBCA]) immediately after biopsy, and no significant HAVF was observed during the ^99mTc-MAA tests; 14 cases (non-medical glue group) were treated with delayed needle extraction or gelatin sponge particle blocking after biopsy, among which 7 cases developed significant HAVF, and the fistulas were treated with NBCA. The LSF of the medical glue group was significantly lower than that of the non-medical glue group ([7.06±2.33] % vs [12.43±7.73] %, P＝0.037). All 21 patients successfully completed ⁹⁰Y-SIRT. Conclusions Liver biopsy may affect ⁹⁰Y-SIRT by causing iatrogenic HAVF. Immediate NBCA-embolization of the needle tract after biopsy or timely NBCA-embolization of fistulas during ^99mTc-MAA tests may reduce the impact.

Objective To study anti-inflammatory activities of oridonin derivatives without Michael fragment. Methods Two oridonin sulfonylureas were designed and synthesized by a photocatalysis reaction and a scaffold hopping strategy. The inhibitory rate of IL-1β was selected for anti-inflammatory activity evaluation. Results Both compound ZM658 and ZM659 revealed potent anti-inflammatory activities with the values of 69.3% and 59.7% in THP-1 cells, respectively. Moreover, two compounds also showed dose-dependent and low cytotoxicity. Conclusion The result indicated that Michael receptor fragment of oridonin could be substituted with sulfonylurea group.

Cardiac arrest (CA) is a serious cardiac event, which has a high incidence and low survival rate at home and abroad. In order to predict the risk of CA in advance, a large number of studies have been conducted by relevant researchers. This paper mainly summarizes the characteristics and research status of the existing analysis and prediction of CA from three aspects: the risk prediction factors of CA, the evaluation index of risk prediction of CA and the early warning scoring system of CA. We hope it can help medical staff to understand the current progress in this field, and provide new ways and methods for predicting the risk of CA.

OBJECTIVE To explore the effect of changing lifestyle diet in the treatment of laryngeal reflux disease(LRPD).METHODS A total of 92 patients with LRPD who received outpatient treatment in the Second Affiliated Hospital of Fujian Medical University from January 2022 to June 2023 were selected as the study control,divided into control group(46 cases)and treatment group(46 cases).The control group was treated with conventional acid suppression and gastric motogenic therapy.The treatment group was treated on the basis of the control group with giving guidance on lifestyle and diet.The changes of reflux symptom index scale(RSI)and reflux sign score scale(RFS)and the clinical efficacy of the two groups were compared 8 weeks and 12 weeks after treatment.RESULTS RSI total score was improved 8 weeks after treatment compared with before treatment in both RSI control group and treatment group(P＜0.05).The total RSI score of 12 weeks after treatment was improved compared with that of 8 weeks after treatment in both control and treatment groups(P＜0.05).The total RFS score at 8 weeks after treatment was improved in both control group and treatment group compared with before treatment(P＜0.05).Compared with 8 weeks after treatment,the total RFS score in both control group and treatment group was improved(P＜0.05).After 8 weeks of treatment,the total effective rate of the control group(60.9%)was compared with that of the treatment group(71.7%),and there was no significant difference between the two groups(χ2=1.335,P=0.513).After 12 weeks of treatment,the total effective rate of the control group(73.9%)was compared with the total effective rate of the treatment group(91.3%),and the difference between the two groups was statistically significant(χ2=6.226,P=0.044).CONCLUSION The change of lifestyle and diet should become an important part of the treatment of LRPD.By adjusting the unhealthy lifestyle and diet,the symptoms of patients can be significantly reduced and better clinical efficacy can be obtained.

Objective:To investigate the value of soluble interleukin-6 (IL-6) receptor (sIL-6R) level in predicting ultrafiltration insufficiency in peritoneal dialysis (PD) patients.Methods:It was a prospective cohort study. The patients who received continuous ambulatory PD and regular follow-up between November 2016 and July 2018 in the PD Center of Renji Hospital, School of Medicine, Shanghai Jiao Tong University were enrolled. Enzyme-linked immunosorbent assay was used to determine dialysate sIL-6R and its appearance rate (AR) was calculated. Patients were divided into high sIL-6R AR group and low sIL-6R AR group according to median value of sIL-6R AR and prospectively followed up until death, PD cessation, or the end of the study (December 31, 2022). Multiple linear regression was used to analyze the related factors of sIL-6R AR. Kaplan-Meier method and log-rank test were used to compare the survival rate difference of ultrafiltration insufficiency between high sIL-6R AR group and low sIL-6R AR group. Multivariate Cox regression and multivariate competing risk models were used to assess the risk factors associated with occurrence of ultrafiltration insufficiency.Results:A total of 198 PD patients were enrolled, including 115 (58.1%) males, with age of (54.9±13.7) years old and PD duration of 22.5 (6.6, 65.0) months. The sIL-6R AR of the cohort was 2 094.7 (1 672.4, 2 920.9) pg/min. Compared with low sIL-6R AR（<2 094.7 pg/min）group, high sIL-6R AR（>2 094.7 pg/min）group had older age ( t=-3.269, P=0.001), higher body mass index ( t=-3.248, P=0.001), proportion of combined diabetes mellitus ( χ2=8.890, P=0.003), 24 h glucose exposure ( Z=-2.257, P=0.024), 24 h ultrafiltration capacity ( Z=-2.515, P=0.012), 4 h dialysate creatinine to serum creatinine ratio ( t=-2.609, P=0.010), mass transfer area coefficient of creatinine ( Z=-2.308, P=0.021), IL-6 AR ( Z=-3.533, P<0.001) and solute glycoprotein 130 AR ( Z=-8.670, P<0.001), and lower serum albumin ( t=2.595, P=0.010) and residual renal function ( t=2.133, P=0.033). Multiple linear regression analysis showed that body mass index ( β=0.194, P=0.005), serum albumin ( β=-0.215, P=0.002) and dialysate lg[IL-6 AR] ( β=0.197, P=0.011) were independently correlated with sIL-6R AR. By the end of the study, 57 (28.8%) patients developed ultrafiltration insufficiency. Kaplan-Meier analysis showed that high sIL-6R AR group had a significantly inferior ultrafiltration insufficiency-free survival rate than that in low sIL-6R AR group (log-rank χ 2=5.375, P=0.020). Multivariate Cox regression analysis and multivariate competing risk models showed that high dialysate sIL-6R AR (>2 094.7 pg/min) was an independent influencing factor of ultrafiltration insufficiency ( HR=2.286 , 95% CI 1.254-4.165 , P=0.007 ; SHR=2.074, 95% CI 1.124-3.828, P=0.020) in PD patients. Conclusions:Dialysate sIL-6R level was associated with body mass index, serum albumin and dialysate IL-6 level. Dialysate sIL-6R may be a predictive factor of ultrafiltration insufficiency in PD patients.

Isocitrate dehydrogenase (IDH) is an essential metabolic enzyme in the tricarboxylic acid cycle (TAC). The high mutation frequency of the IDH gene plays a complicated role in gliomas. In addition to affecting gliomas directly, mutations in IDH can also alter their immune microenvironment and can change immune-cell function in direct and indirect ways. IDH mutations mediate immune-cell infiltration and function by modulating immune-checkpoint gene expression and chemokine secretion. In addition, IDH mutation-derived D2-hydroxyglutarate can be absorbed by surrounding immune cells, also affecting their functioning. In this review, we summarize current knowledge about the effects of IDH mutations as well as other gene mutations on the immune microenvironment of gliomas. We also describe recent preclinical and clinical data related to IDH-mutant inhibitors for the treatment of gliomas. Finally, we discuss different types of immunotherapy and the immunotherapeutic potential of IDH mutations in gliomas.

Objective:To observe whether endoplasmic reticulum stress and NOD-like receptor protein 3 (NLRP3) inflammasome activation were involved in severe heat stroke induced intestinal mucosal injury and to investigate the potential protective effect of the endoplasmic reticulum stress inhibitor 4-phenylbutyric acid (4-PBA).Methods:Thirty male BALB/c mice were randomly (random number) assigned to 3 groups: the control group, heat stroke group (HS), and 4-PBA pretreatment group (4-PBA+HS, 4-PBA 120 mg/kg, intraperitoneal injection). Mice in the control group were placed at room temperature, while mice in the HS group and 4-PBA+HS group were placed in a prewarmed chamber [temperature (35.5±0.5) °C, humidity (60.0±5.0)%]. A rectal temperature (Tc) that reached 42 °C was considered to indicate severe heat stroke. The concentrations of malondialdehyde (MDA) and superoxide dismutase (SOD) in intestinal homogenate were analyzed by a colorimetric method, serum interleukin-1β (IL-1β) and interleukin-18 (IL-18) were assessed by ELISA, intestinal histopathology was evaluated by hematoxylin and eosin (HE) staining, intestinal ultrastructure was observed by electron microscopy, and the protein expression of GRP78, CHOP, NLRP3 and cleaved caspase-1 were analyzed by Western blot. Data were statistically analyzed by ANOVA test and LSD- t multiple comparison test if homogeneous variance, or analyzed by Welch test and Dunnett's T3 multiple comparison test if heterogeneous variance. Results:The concentration of MDA in the HS group was increased ( t=14.243, P<0.01), while SOD was decreased compared with that in the control group ( t=7.781, P<0.01), and the concentrations of serum IL-1β and IL-18 were significantly elevated ( t=12.664, P<0.01; t=16.240, P<0.01). Under light microscopy, extensive destruction of small intestinal villi and inflammatory cell infiltration were observed in the intestines of mice with severe heat stroke. Transmission electron microscopy showed that endoplasmic reticulum structures were significantly expanded, and mitochondria were vacuolated in the intestines of mice with severe heat stroke. Compared with those in the control group, the protein expression levels of GRP78, CHOP, NLRP3 and cleaved caspase-1 in the small intestine were elevated in the HS group ( t=14.824, P <0.01; t=12.667, P<0.01; t=9.298, P<0.01; and t=6.588, P=0.001). Compared with those in the HS group, mice in the 4-PBA pretreatment group exhibited reduced concentrations of MDA ( t=9.167, P<0.01), increased SOD ( t=6.077, P<0.01) , and reduced serum IL-1β and IL-18 levels ( t=4.889, P= 0.001; t=5.693, P<0.01). In addition, 4-PBA pretreatment significantly alleviated the pathological disruption and ultrastructural damage to small intestine tissues. Moreover, 4-PBA pretreatment reduced GRP78, CHOP , NLRP3 and cleaved caspase-1 protein expression ( t=9.080, P<0.01; t=7.152, P<0.01; t=4.249, P=0.005; t=3.650, P=0.011). Conclusions:Endoplasmic reticulum stress and NLRP3 inflammasome are involved in intestinal mucosal injury induced by severe heat stroke. 4-PBA plays a protective role by alleviating endoplasmic reticulum stress and NLRP3 inflammasome activation.
