Objective To investigate the seroprevalence of antibody against Toxoplasma gondii among patients with hematological malignancies, and compare it with that among health individuals, so as to provide insights into unraveling the pathogenesis of hematological malignancies. Methods A total of 225 patients with hematological malignancies in Department of Hematology, Xuzhou Central Hospital and 300 healthy individuals in the same hospital were enrolled from 2017 to 2024. Blood samples were collected from all subjects, and the serum IgG and IgM antibodies against T. gondii were detected using chemiluminescent immunoassay. Demographic and clinical features were collected from patients with hematological malignancies, including gender, age, contact with cats, consumption of raw or undercooked meat, type of malignancy, clinical symptoms, blood transfusion and treatment, and the seroprevalence of anti-T. gondii antibody was compared among patients with different characteristics. Results The age (t = 0.72, P > 0.05) and gender (χ² = 0.93, P > 0.05) were compared between patients with hematological malignancies and healthy individuals. The seroprevalence of T. gondii infection was 20.89% among patients with hematological malignancies and 4.33% among healthy individuals (χ² = 34.81, P < 0.01), and the seroprevalence of anti-T. gondii IgG antibody was 20.89% among patients with hematological malignancies and 4.33% among healthy individuals (χ² = 34.81, P < 0.01), while there was no significant difference in the seroprevalence of anti-T. gondii IgM antibody between patients with hematological malignancies and healthy individuals (1.33% vs. 0; corrected χ² = 2.02, P > 0.05). The seroprevalence of T. gondii infection was 23.08% among patients with leukemia, 16.67% among patients with lymphoma, 19.23% among patients with multiple myeloma, 24.00% among patients with myeloproliferative neoplasm, and 26.09% among patients with myelodysplastic syndrome (χ² = 1.44, P > 0.05), and was all higher than among healthy individuals (corrected χ² = 23.92, 10.74, 13.76, 12.84 and 14.54; all P values < 0.01). In addition, there were no significant differences in the detection of anti-T. gondii antibody among patients with hematological malignancies in terms of gender, age, contact with cats, consumption of raw or undercooked meat, chemotherapy or blood transfusion (χ² = 0.76, 1.97, 0, 2.81, 2.38 and 0.66; all P values > 0.05). Conclusions There is a high risk of T. gondii infection among patients with hematological malignancies, and intensified surveillance of T. gondii infection is recommended among patients with hematological malignancies.

OBJECTIVE To explore the significance of pharmaceutical care through the diagnosis and treatment of a patient with exogenous insulin autoimmune syndrome （EIAS）， combined with the analysis of literature reports. METHODS Clinical pharmacist participated in the diagnosis and treatment process of one case of EIAS. Based on the characteristics of the patient’s condition， the pharmacist provided medication suggestions and formulated pharmaceutical monitoring measures. At the same time， the pharmacist searched for relevant literature on insulin autoimmune syndrome （IAS） and EIAS， extracted data （gender， age， occurrence time， laboratory tests， clinical symptoms， intervention and outcome）， and conducted analysis. RESULTS Based on the patient’s medication information in the past 3 years， clinical pharmacist determined that the EIAS was likely caused by insulin aspartate 30. The clinician adopted the clinical pharmacist’s suggestion to discontinue insulin and switch to oral hypoglycemic drugs. The patient improved after treatment. The literature analysis showed that among the 257 patients with IAS reported， 212 cases were caused by drugs； among them， 23 cases were caused by lipoic acid， and 56 cases were caused by exogenous insulin. There were no significant differences in age， glycosylated hemoglobin， and body mass index between the two groups. The lowest blood glucose level in the lipoic acid group was significantly lower than that in the exogenous insulin group （P＜0.05）. The proportion of females and the proportion of fasting insulin ≥ 1 000 μU/mL were significantly higher in the lipoic acid group than in the exogenous insulin group （P＜0.05）. CONCLUSIONS Compared with EIAS， lipoic acid-induced IAS usually causes more severe hypoglycemia， and the fasting insulin level is usually higher than 1 000 μU/mL， which is more common in female patients. The participation of clinical pharmacists in the diagnosis and treatment of EIAS can help improve the diagnosis and treatment level of similar rare diseases and ensure the safety of patients’ medication.

ObjectiveTo compare the clinical features of patients with hepatitis B virus （HBV）-related early-onset liver cancer and those with late-onset liver cancer， to assess the severity of the disease， and to provide a theoretical basis for the early diagnosis and treatment of liver cancer. MethodsA retrospective analysis was performed for 695 patients who were diagnosed with HBV-related liver cancer for the first time in Guangzhou Eighth People’s Hospital， Guangzhou Medical University， from January 2019 to August 2023， among whom 93 had early-onset liver cancer （defined as an age of50 years for female patients and40 years for male patients） and 602 had late-onset liver cancer （defined as an age of ≥50 years for female patients and ≥40 years for male patients）. Related clinical data were collected， including demographic data， clinical symptoms at initial diagnosis， comorbidities， smoking history， drinking history， family history， routine blood test results， biochemical parameters of liver function， serum alpha-fetoprotein（AFP）， virological indicators， coagulation function， and imaging findings. The pan-inflammatory indices neutrophil-to-lymphocyte ratio （NLR）， platelet-to-lymphocyte ratio （PLR）， and lymphocyte-to-monocyte ratio （LMR） were calculated， as well as FIB-4 index， aspartate aminotransferase-to-platelet ratio index （APRI）， S index， Model for End-Stage Liver Disease （MELD） score， Child-Turcotte-Pugh （CTP） score， albumin-bilirubin （AIBL） grade， and Barcelona Clinic Liver Cancer （BCLC） stage. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or Fisher’s exact test were used for comparison of categorical data between two groups. ResultsThere were significant differences between the two groups in the proportion of male patients and the incidence rates of diabetes， hypertension， and fatty liver disease （χ²=6.357， 15.230， 11.467， and 14.204， all P0.05）， and compared with the late-onset liver cancer group， the early-onset liver cancer group had a significantly higher proportion of patients progressing to liver cancer without underlying cirrhosis （χ²=24.657， P0.001） and a significantly higher proportion of patients with advanced BCLC stage （χ²=6.172， P=0.046）. For the overall population， the most common clinical symptoms included abdominal distension， abdominal pain， poor appetite， weakness， a reduction in body weight， edema of both lower limbs， jaundice， yellow urine， and nausea， and 55 patients （7.9%） had no obvious symptoms at the time of diagnosis and were found to have liver cancer by routine reexamination， physical examination suggesting an increase in AFP， or radiological examination indicating hepatic space-occupying lesion； compared with the late-onset liver cancer group， the patients in the early-onset liver cancer group were more likely to have the symptoms of abdominal distension， abdominal pain， and jaundice （all P0.05）. Compared with the late-onset liver cancer group， the early-onset liver cancer group had a significantly larger tumor diameter （Z=2.845， P=0.034）， with higher prevalence rates of multiple tumors and intrahepatic， perihepatic， or distant metastasis （χ²=5.889 and 4.079， both P0.05）， and there were significant differences between the two groups in tumor location and size （χ²=3.948 and 11.317， both P0.05）. Compared with the late-onset liver cancer group， the early-onset liver cancer group had significantly lower FIB-4 index， proportion of patients with HBsAg ≤1 500 IU/mL， and levels of LMR and Cr （all P0.05）， as well as significantly higher positive rate of HBeAg and levels of log₁₀ HBV DNA， AFP， WBC， Hb， PLT， NLR， PLR， TBil， ALT， Alb， and TC （all P0.05）. ConclusionCompared with late-onset liver cancer， patients with early-onset liver cancer tend to develop liver cancer without liver cirrhosis and have multiple tumors， obvious clinical symptoms， and advanced BCLC stage， which indicates a poor prognosis.

OBJECTIVE To explore the independent factors affecting tissue inflammatory cells changes in recurrent nasal polyps.METHODS The clinical data of 31 patients with nasal polyps who underwent endoscopic surgery at the Department of Otolaryngology Head and Neck Surgery,Yantai Yuhuanding Hospital from December 2007 to December 2021 were selected and analyzed by stepwise regression logistic analysis.RESULTS The number of tissue inflammatory cells in recurrent nasal polyps changed compared with that in primary nasal polyps,and the number and percentage of neutrophils in recurrent polyps increased(P<0.05).Logistic analysis revealed that smoking was an independent risk factor for eosinophilia in recurrent nasal polyps,increasing age was an independent factor for lowering neutrophils,and the comorbid allergic rhinitis and the time interval of recurrence were independent factors for lowering and increasing lymphocytes,respectively.CONCLUSION The number of tissue-infiltrating cells is altered in recurrent polyps compared with primary polyps.Smoking is an independent risk factor for eosinophilia in recurrent polyps.

Purpose To investigate the predictive value of chest CT-based radiomics for spread through air spaces in stage T1 peripheral type lung cancer.Materials and Methods A total of 173 patients with surgically pathologically confirmed stage T1 non-small cell lung cancer were retrospectively collected and divided into positive group(49 cases)and negative group(124 cases)according to the presence or absence of spread through air spaces.All lesions were randomly divided into training set(122 cases)and validation set(51 cases)according to the ratio of 7∶3.The primary area of lung cancer(the main body of the lesion),the peripheral infiltrative area(a 5-mm annular area expanding outward along the edge of the lesion)and the tumor margin area(a 5-mm annular area retracting inward along the edge of the lesion)were used as areas of interest to extract imaging histological features.Three imaging histological models were established for the primary area of lung cancer,the peripheral infiltrative area and the tumor margin area,and combined with the morphological features of CT to establish three combined models.The efficacy of each model was evaluated and the optimal model was selected.Results The lobulation signs of positive group was significantly more than that of negative group(χ2=9.946,P=0.002).The area under the curve(AUC)of the imaging histological model based on the three regions of interest were 0.899,0.825,0.840 for the training group and 0.876,0.811 and 0.832 for the validation group,respectively.The model with the highest AUC was the primary tumor imaging model(P=0.043,P<0.001,P=0.017),the AUC of the combined model established by adding the lobar sign were 0.917,0.835 and 0.851,respectively.The AUC of the three regions of interest in the validation group were 0.912,0.832,and 0.845 and the highest AUC was found in the primary tumor area(P<0.001,P=0.017,P=0.049).Conclusion It is feasible to study lung cancer with airway metastasis via CT-based radiomics,taken lobulation signs as the risk predictive factor.

Objective To investigate the correlation between serum Angiopoietin-like protein 4(ANGPTL4)and soluble bone marrow cell-like transcription factor-1(sTLT-1)levels and cognitive function and prognosis in elderly patients with vascular dementia(VD).Methods A total of 92 elderly patients with vascular dementia admitted to Hebei Yanda Hospital from June 2020 to June 2022 were selected as the study group.They were divided into mild(n=30),moderate(n=36)and severe groups(n=26)according to the minimum mental state examination(MMSE)score,and 92 patients with healthy physical examination during the same period were selected as the control group.According to the prognosis of patients,the cognitive dysfunction was divided into grade Ⅰ～Ⅱ and grade Ⅲ.ELISA method was used to detect the levels of serum ANGPTL4 and sTLT-1.Pearson and Spearman methods were used to analyze the correlation between serum ANGPTL4 and sTLT-1 and MOCA scores.Logistic regression analysis was used to analyze the influencing factors of the prognostic grade Ⅲ of elderly patients with vascular dementia.The receiver operating characteristic(ROC)curve was plotted to analyze the predictive value of serum ANGPTL4 and sTLT-1 levels in the prognostic grade Ⅲ in elderly patients with vascular dementia.Results The serum ANGPTL4 level(987.57±53.25 pg/ml)in the study group was lower than that in the control group(1 108.35±62.13 pg/ml),and the serum sTLT-1(68.01±5.15 pg/ml)level was higher than that in the control group(50.12±4.57 pg/ml),with significant differences(t=14.158,24.922,all P＜0.05).Serum ANGPTL4 levels and MOCA scores were decreased sequentially in the mild,moderate and severe groups(F=33.495,66.617),while serum sTLT-1 level was increased sequentially(F=66.718),and the differences were statistically significant(all P＜0.05),respective.Pearson analysis showed that serum ANGPTL4 was negatively correlated with sTLT-1(r=-0.621,P＜0.05).Spearman analysis showed serum levels of ANGPTL4 and sTLT-1 were positively and negatively correlated with MoCA scores,respectively(r=0.545,-0.557,all P＜0.05).The serum ANGPTL4 level(953.45±51.16 pg/ml)in the prognostic patients of grade Ⅲ was lower than that of grade Ⅰ～Ⅱ(1 005.76±54.27 pg/ml),and the serum level of sTLT-1(73.14±5.40 pg/ml)was higher than that of grade Ⅰ～Ⅱ(65.28±5.02 pg/ml),with significant differences(t=4.490,6.967,all P＜0.05).Logistic regression analysis showed low expression of ANGPTL4[OR(95％CI):5.089(1.833～14.129)]and high expression of sTLT-1[OR(95％CI):4.258(1.739～10.428)]were risk factors affecting the prognosis of elderly patients with vascular dementia(P＜0.05).According to the ROC curve,the combined prediction of two for the grade Ⅲ prognosis of elderly vascular dementia patients was better than the individual prediction of ANGPTL4 and sTLT-1(Z=2.135,3.268,all P＜0.05).Conclusion Serum ANGPTL4 level was decreased but sTLT-1 level was increased in elderly patients with vascular dementia,and ANGPTL4 and sTLT-1 were closely related to cognitive function and prognosis.

Objective To explore the association between peripheral retinal defocus and myopia in adolescents.Methods This study encompassed 192 adolescents(192 right eyes),aged between eight and fifteen years,who sought treatment at Ineye Hospital of Chengdu University of TCM from October 2022 to April 2023.Based on the spherical equiva-lent(SE),the patients were divided into three groups:Emmetropia(E),low myopia(LM),and moderate myopia(MM),with each group comprising 64 patients(64 right eyes).After mydriatic refraction,the SE values were documen-ted.Ocular biological parameters,including axial length(AL),central corneal thickness(CCT),lens thickness(LT),and keratometry values(K1,K2),were obtained using IOL Master 900.Multispectral refraction topography was employed to measure the retinal defocus:positive values indicated hyperopic defocus,while negative ones represented myopic defocus.With the macular fovea as the center,the total retinal defocus value was recorded as TRDV.The ring partition(eccentrici-ty)was divided into 0°-10°、＞10°-20°、＞20°-30°、＞30°-40°、＞40°-53°,which was recorded as RDV-0°-10°,RDV-10°-20°,RDV-20°-30°,RDV-30°-40°,and RDV-40°-53°,respectively;the quadrants were recorded as RDV-Superior(RDV-S),RDV-Inferior(RDV-I),RDV-Temporal(RDV-T)and RDV-Nasal(RDV-N),respectively.The variance of RDV across different ranges was analyzed using One-Way ANOVA and non-parametric tests.The associations between SE,AL and RDV were examined using Spearman and Pearson correlation analyses.Results The RDV-20°-30°,RDV-30°-40° and RDV-40°-53° of Groups E,LM and MM all exhibited hyperopic defocus.Statistically significant differences were identi-fied in TRDV,RDV-10°-20°,RDV-20°-30°,RDV-30°-40°,RDV-40°-53°,RDV-S,RDV-T and RDV-N among the three groups(all P＜0.05).TRDV,RDV-20°-30°,RDV-30°-40°,RDV-40°-53°,RDV-S,RDV-T,and RDV-N were found to be negatively correlated with SE while positively correlated with AL(all P＜0.05).RDV-0°-10° and RDV-I were uncorrelated with both SE and AL(all P＞0.05);RDV-10°-20° was positively correlated with AL(P=0.012)while uncorrelated with SE(P=0.233).Conclusion Peripheral retinal hyperopic defocus tends to advance with escalating eccentricity and my-opia.Peripheral retinal defocus is asymmetrical.Peripheral(10°-53°),superior,nasal and temporal retinal defocus may be closely related to the development of myopia.

Objective To explore the changes in periretinal defocus and visual quality after femtosecond laser-assis-ted in situ keratomileusis(FS-LASIK).Methods Fifty-one myopic patients(102 eyes)who underwent FS-LASIK at the Ineye Hospital of Chengdu University of Traditional Chinese Medicine from March to May 2023 were selected for the study,including 27 females(54 eyes)and 24 males(48 eyes).The defocus around the retina was measured using a multispectral refraction topography,and the total refraction difference value(TRDV)was recorded.The refraction difference value(RDV)in four quadrants:superior RDV(RDV-S),inferior RDV(RDV-I),nasal RDV(RDV-N),and temporal RDV(RDV-T),as well as the RDV in the concentric ring areas corresponding to 10°,20°,30°,40°,and 53° from the fovea of the mac-ula(represented as RDV 0°-10°,RDV 10°-20°,RDV 20°-30°,RDV 30°-40°,and RDV 40°-53°,respectively)were also re-corded.The objective scattering index(OSI),Strehls ratio(SR),modulation transfer function(MTF)values(represen-ted as 10 c·d-1 MTF,20 c·d-1 MTF,and 30 c·d-1MTF,respectively)and cutoff frequencies(MTF cutoff)at the spa-tial frequencies of 10 c·d-1,20 c·d-1 and 30 c·d-1 were measured and recorded using a visual quality analysis system.The data of corneal vertical trefoil(Z3-3),vertical coma(Z3-1),horizontal coma(Z31),horizontal trefoil(Z33),vertical tetrafoil(Z4-4),vertical secondary astigmatism(Z4-2),spherical aberration(Z40),horizontal secondary astigmatism(Z42),horizontal tetrafoil(Z44),and total higher-order aberration(HOA)were measured and recorded using the iTrace aberration meter.The measurement data of patients before surgery,one month after surgery,and three months after sur-gery were compared,and their correlations were analyzed.Results TRDV,RDV-S,RDV-N,RDV 20°-30°,RDV 30°-40°,and RDV 40°-53° around the retina of patients decreased one month and three months after surgery compared with those be-fore surgery,and the differences were statistically significant(all P＜0.001).There were statistically significant differences in OSI,MTF cutoff,and 10 c·d-1 MTF among patients before surgery,one month after surgery,and three months after surgery(all P＜0.05).There were statistically significant differences in corneal Z3-3,Z3-1,Z31,Z33,Z4-4,Z4-2,Z40,Z42,Z44,and HOA among patients before surgery,one month after surgery,and three months after surgery(all P＜0.001).The Pearson correlation analysis results showed that,ΔRDV 0°-10° was positively correlated with ΔZ3-3,ΔZ31,ΔZ4-2,ΔZ40,and ΔZ42(all P＜0.05);ΔRDV 10°-20° was positively correlated with ΔZ4-4 and ΔZ4-2(both P＜0.05);ΔRDV 20°-30° was positively correlated with ΔZ4-4 and ΔZ44(both P＜0.05);ΔTRDV and ΔRDV 40°-53° were negatively correla-ted with ΔHOA(both P＜0.05).ΔRDV-S and ΔZ3-1 were negatively correlated with ΔHOA(both P＜0.05)and positively correlated with ΔZ44(P＜0.05);ΔRDV-N was positively correlated with ΔZ4-4(P＜0.05).Conclusion FS-LASIK can reduce periretinal hyperopic defocus in myopic patients,but it introduces corneal HOA,and there is a certain correlation between the two.

Objective:To investigate the impact of elevated glucose-induced RNA oxidation on pancreatic β-cell function, activity, and underlying molecular mechanisms.Methods:Rat pancreatic islet β-cell tumour INS-1 cells were cultured in vitro and subjected to nucleic acid oxidation assessment using isotope dilution ultra-high performance liquid tandem mass spectrometry(ID LC MS/MS)following high glucose exposure.In vitro simulation of increased RNA oxidation in INS-1 cells was achieved using 8-oxoguanosine-5'-triphosphate(8-oxoGTP).Cell proliferation was evaluated through CCK-8 assay, apoptosis was measured via flow cytometry, and gene expression of insulin(INS), pancreatic-duodenal homologous cassette 1(PDX1), cysteine-aspartate proteinase 3(Casp3), and cysteine aspartate protease 6(Casp6)was analyzed at the mRNA level.Additionally, whole transcriptome sequencing was performed to elucidate the molecular mechanisms underlying the impact of RNA oxidation on INS-1 cells.Results:Elevated glucose levels induced an increase in RNA oxidation within INS-1 cells.This heightened RNA oxidation led to the inhibition of INS-1 cell proliferation, a reduction in mRNA levels of INS and PDX1 genes, and the promotion of apoptosis-related casp3 and casp6 gene mRNA synthesis.Transcriptome sequencing analysis unveiled that the elevated RNA oxidation caused differential expression of mRNA, lncRNA, miRNA, and circRNA in INS-1 cells.This included a significant down-regulation of transcription factors such as Mafa, Pdx1, Pax6, and Mnx1, alongside an up-regulation of various miRNAs like rno-miR-124-3p, rno-miR-133a-3p, rno-miR-3120, rno-miR-212-3p, and rno-miR-7a-2-3p.These molecular changes contributed to the altered expression of associated lncRNAs, ultimately hindering insulin synthesis and secretion, as well as β-cell proliferation.Conclusions:Increased RNA oxidation down-regulates the levels of key β-cell transcription factor mRNAs, contributes to the differential expression of related non-coding RNAs(ncRNAs), particularly lncRNAs, impacts β-cell insulin synthesis and secretion, hinders cell proliferation, and serves as a significant factor in β-cell dysfunction and decreased activity in type 2 diabetes mellitus(T2DM).

Objective:To observe any effect of dynamic scalp acupunture on the lower limb motor function and balance of stroke survivors.Methods:Eighty-two hemiplegic stroke survivors were randomly divided into a traditional scalp acupuncture group and a dynamic scalp acupuncture group, each of 41. In addition to routine symptom support treatment, the traditional scalp acupuncture group was given daily scalp acupuncture treatment and lower limb motor training 5 times a week for 3 consecutive weeks. The dynamic scalp acupuncture group was treated separately on the same schedule. Before and after the treatment, all were evaluated using the lower extremity part of the Fugl-Meyer motor function scale (FMA-LE), the Berg Balance Scale (BBS), the modified Barthel index (MBI) and functional ambulation categories (FAC).Results:Where was no significant difference between the two groups in any of the measurements before the treatment. Afterward the average FMA-LE, MBI and BBS scores of both groups had increased significantly, with greater improvement in the dynamic scalp acupuncture group. There was no significant difference in the two groups′ average functional ambulation categorization after the treatment.Conclusions:Dynamic scalp acupunture can effectively improve the lower limb motor function and balance of stroke survivors.
