This article retrospectively analyzed the clinical data of three recipients who developed acute antibody mediated rejection (AMR) after receiving different courses of immunotherapy prior to liver transplantation for hepatocellular carcinoma. It focused on their diagnostic and therapeutic processes, including the immunosuppressive induction regimen [rabbit anti-human thymocyte globulin (rATG) + methylprednisolone] , postoperative liver function changes, diagnostic methods for acute AMR (such as allograft liver biopsy, panel reactive antibody testing, and donor-specific antibody testing) , and the combination treatment strategies used (rATG, rituximab, intravenous immunoglobulin, and plasma exchange). The aim of this article is to summarize the clinical characteristics, diagnosis, and treatment experiences of acute AMR occurring after liver transplantation in patients with liver cancer who had received immunotherapy, explore the potential risks involved, and provide a reference for clinicians in managing such cases.

Bovine neosporosis,a significant disease affecting the livestock industry,is caused by the protozoan parasite Neospora caninum(N.caninum).The current absence of efficacious vaccines and therapeutics necessitates the exploration of novel interventions.Cordycepin,a bioactive nucleo-side derived from Cordyceps militaris,has garnered attention for its diverse pharmacological properties.This study endeavors to elucidate the inhibitory effects of cordycepin on N.caninum in-fection.The cytotoxicity of cordycepin to bovine macrophages was assessed using the CCK-8 assay to ascertain a non-toxic concentration range.The impact of cordycepin on the N.caninum burden within bovine macrophages was evaluated using qPCR analysis and immunofluorescence assays.Additionally,the modulation of cytokine,interferon,and defensin expression induced by N.cani-num in the presence of cordycepin was examined through qRT-PCR analysis.The results showed that cordycepin exhibited negligible cytotoxicity to bovine macrophages at concentrations ranging from 2.812 5 to 180.000 0 μmol/L,compared to the control group.At concentrations of 5.625 0,11.250 0,and 22.500 0 μmol/L,cordycepin significantly reduced the intracellular N.caninum loads and diminished the intensity of intracellular parasite fluorescence.While N.caninum infection downregulated the expression of pro-inflammatory cytokines such as TNF-α,IL-1β,and IL-6,cordycepin treatment robustly induced their expression.Furthermore,although cordycepin treatment reduced the expression levels of IFN-α,IFN-β,and IFN-γ that were upregulated by N.caninum infection,it maintained substantial expression levels.In conclusion,cordycepin demon-strates a promising resistance against N.caninum infection,suggesting its potential as a therapeu-tic agent for the treatment of bovine neosporosis.

On the premise of ensuring system accuracy,lightweight models can be deployed on embedded devices or mobile terminals with limited hardware resources.Therefore,a method using modified lightweight residual network is proposed for arrhythmia classification.The method transforms one-dimensional electrocardiogram data into Gramian angular summation field maps which are then taken as the model input,and reduces the number of model parameters by substituting ShuffleNet V2 convolutional units for the traditional convolution inside the ResNet34 basic residual blocks.In addition,the network incorporating efficient channel attention module makes the model focus on important feature regions,thereby improving model accuracy and realizing the automatic arrhythmia classification.The proposed model has an accuracy of 99.78%on MIT-BIH arrhythmia database,and it reduces the number of parameters,FLOPs and MAdd by 95%,91%and 91%,as compared with the traditional ResNet34 model,demonstrating its characteristics of lightweight and high accuracy,and proving the possibility of deployment on mobile devices.

Objective To investigate the effects of different medical nutrition therapy on blood glucose variability in elderly patients with type 2 diabetes .Methods Eighty‐five patients with type 2 diabetes were randomly divided into three groups ,29 cases in the control group ,27 cases in the low GI diet group ,29 cases in water‐soluble dietary fiber group .Each patient was established a individuality diabetic diet recipe according to the guidelines of medical nutrition therapy ,combined with oral hypoglycemic agents , The breakfast and dinner for patients in low GI diet group were completely instead of low GI diet ,while the breakfast and dinner for patients in water‐soluble dietary fiber group were added 10 g dietary fiber .Blood glucose ,blood lipid ,renal function and blood glu‐cose fluctuation were observed before and after one‐month intervention .Results Compared with before intervention ,the concentra‐tion of blood glucose after the intervention in each group were decreased (P < 0 .05) ,the glucose fluctuation index in low GI diet group and water soluble dietary fiber group decreased obviously after the intervention (P< 0 .05) .After the intervention ,average fasting blood glucose ,postprandial glucose average ,and mean blood glucose in low GI diet group were significantly lower than those in control group (P< 0 .05) ,Meanwhile ,the blood sugar standard deviation and MAGE in low GI dietary intervention group and in water‐soluble dietary fiber group were significantly lower than that of control group (P< 0 .05) .Conclusion On the basis of the di‐abetes diet recipes and oral drug treatment giving low GI dietary replacement therapy or adding water soluble dietary fiber ,for eld‐erly patients with type 2 diabetes ,could effectively control the blood glucose level ,and significantly reduce glucose variability .

Objective To study the relationship between plasma free fatty acids composition and the incidence of nonalcoholic fatty liver disease(NAFLD) .Methods By the design of case‐control study ,105 patients with NAFLD as cases and 110 healthy peo‐ple as controls were enrolled into the study .Plasma free fatty acid levels were determined by gas chromatography .Results High level of plasma palmitic acid(C16 :0)(OR=1 .769) was the risk factors of NAFLD ,while plasma levels of linoleic acid(C18 :2 n‐6) (OR=0 .855) and arachidonic acid(C20 :4 n‐6)(OR=0 .181)were negatively associated with the incidence of NAFLD .Conclusion These findings suggest that a proper ratio of diet fatty acids intake may reduce the risk of NAFLD .

Objective To study the effects of retinoic acid on the radiation sensitivity in HL-60 cells transfected with the IFN? expression vector containing retinoic acid response element and its possible mechanism.Methods HL-60 cells were transfected with pRARE4-IFN?,then treated by all-trans retinoic acid at the dose of 2?10~(-7)mol/L and/or irradiation under 4 Gy.The cellular proliferation capacity was observed with MTT assay,the cell apoptosis was measured with DNA fragmentation rate,the protein expression of caspase-3 was analyzed with Western blotting.Meanwhile,the activity of caspase-3 was examined.Results After HL-60 and HL-60~(IFN?)cells were treated by RA and/or radiation,the cellular proliferation capacity was decreased,the DNA fragmentation rate was increased,the protein expression and activity of caspase-3 were up-regulated.These changes were more apparent in transfected cells than non-transfected cells,and more significant in cells treated by radiation and RA than that treated by radiation or RA alone.The special caspase-3 inhibitor,DEVD-CHO could inhibit the activity of caspase-3 and impair the growth inhibition and apoptosis induced by RA and/or radiation.Conclusion Our study demonstrated that DNA fragmentation and growth inhibition of transfected and non-transfected cells induced by radiation could be enhanced with RA.The up-regulated expression and activity of caspase-3 may play a partial role in cell apoptosis induced by RA and radiation.
