One case of non-small cell lung adenocarcinoma patient developed severe liver injury(ALT 319.6 U·L-1,AST 103.3 U·L-1,ALP 586.8 U·L-1,DBIL 104.0 μmol·L-1,TBIL 172.3 μmol·L-1,IBIL 68.3 μmol·L-1),after multiple cycles of chemotherapy combined with camrelizumab.Subsequently,fever and jaundice on the face and sclera were noticed.Based on the previous medication,the RUCAM scale and the R value was used to evaluated the symptons,suggested a high likelihood of drug-induced cholestatic liver injury caused by camrelizumab.Clinical pharmacist proposed drug therapy recommendations for liver injury treatment and the selection of protective drugs.The physician adopted some of these therapeutic suggestions,and the patient was treated with methylprednisolone and hepatoprotective drugs.Although there was a temporary improvement in transaminase levels,bilirubin levels continued to rise.Later,the patient asked to discharge and passed away at home.Immune-related cholestatic liver injury caused by camrelizumab is insensitive to glucocorticoid therapy,clinicians should promptly consider adding immunosuppressants to enhance prognosis.Literature studies have shown that dual-molecule plasma adsorption system sequential plasma exchange has a certain therapeutic effect on immune-related cholestatic liver injury.

Objective:To evaluate the safety and efficacy of mitoxantrone liposome (MIT-LIP) combined chemotherapy in treating mixed phenotype acute leukemia (MPAL) .Methods:December 2021 to November 2024, MPAL patients who underwent the MAED (MIT-LIP + cytarabine + etoposide + dexamethasone) regimen were retrospectively analyzed. Data on clinical characteristics, adverse reactions, therapeutic outcomes, and long-term prognoses were collected.Results:A total of 7 MPAL patients who received MAED regimen were admitted. Among them, two patients were initially diagnosed with T-ALL or B-ALL, respectively, and transformed into AML after treatment. Three patients were initially diagnosed as MPAL (B/myeloid), one as MPAL (T/myeloid), and one with MPAL (myeloid/plasmacytoid dendritic cell). Among the 7 patients, there were 3 males and 4 females, 1 chromosome abnormalities and 6 gene abnormalities, including 1 case with BCR∷ABL fusion gene. The median age was 38 years (range: 16–58 years). There was no clear related drug allergy and organ toxicity during MAED regimen, and the main adverse effect was hematological toxicity. After induced chemotherapy, all patients achieved complete remission (CR), 2 maintained MRD-negative CR and 1 maintained MRD-positive CR. The other 4 patients underwent allogeneic hematopoietic stem cell transplantation, 2 maintained MRD-negative CR, and 2 relapsed. The current median follow-up time was 12 months, the overall survival (OS) rate was 100%, the relapse-free survival (RFS) rate was 60%, and the median OS time and median RFS time were not reached.Conclusion:The MAED regimen demonstrates high safety and a favorable CR rate in MPAL treatment.

Objective To investigate the predictive value of serum homocysteine(HCY)and lipoprotein(a)[Lp(a)]in autologous arteriovenous fistula(AVF)failure in patients undergoing maintenance hemodialy-sis(MHD).Methods A total of 175 patients with MHD admitted to the hospital from January to December 2022 were selected as the observation group,among them,103 patients without AVF failure were selected as observation group 1,and 72 patients with AVF failure were selected as observation group 2.175 healthy indi-viduals who underwent physical examinations at the outpatient examination center of the hospital during the same period were selected as the control group.Enzyme-linked immunosorbent assay was used to detect the levels of HCY and Lp(a).Pearson method was used to analyze the correlation between HCY,Lp(a)with clin-ical indicators.Multivariate Logistic regression analysis was performed to analyze the influencing factors of AVF failure in MHD patients.Receiver operating characteristic(ROC)curve was plotted to analyze the pre-dictive value of serum HCY and Lp(a)for AVF failure in MHD patients.Results Compared with the control group,the serum levels of HCY and Lp(a)in observation group 1 were increased(P<0.05).Compared with the control group and observation group 1,the serum levels of HCY and Lp(a)in observation group 2 were in-creased(P<0.05).The serum levels of HCY and Lp(a)in observation group 2 were negatively correlated with ultrafiltration amount(P<0.05),and HCY and Lp(a)were positively correlated with parathyroid hor-mone(PTH),blood phosphorus(P),uric acid(UA)(P<0.05).Multivariate Logistic regression analysis showed that HCY,Lp(a),PTH,P,UA,diabetic nephropathy,duration of endovascular fistula use≥12 months,duration of puncture point compression≥30 min,and arteriovenous internal diameter<2 mm and vascular stenosis were the risk factors for AVF failure in MHD patients(P<0.05),and ultrafiltration a-mount was a protective factor for AVF failure in MHD patients(P<0.05).ROC curve results showed that the area under the curve of HCY and Lp(a)alone and in combination in the prediction of AVF failure in MHD patients were 0.822,0.820 and 0.908,respectively(Zcombination vs.HCY=3.144,Zcombination vs.Lp(a)=2.925,P<0.05).Conclusion The serum levels of HCY and Lp(a)in MHD patients with AVF failure are increased.They are the influencing factors of AVF failure in MHD patients,and the value of the combination of the two for pre-dicting AVF failure in MHD patients is relatively high.

Background and Purpose:The early prediction of local tumor progression-free survival(LTPFS)after radiofrequency ablation(RFA)for colorectal cancer(CRC)lung metastases has significant clinical importance.The application of radiomics in the prediction of tumor prognosis has been explored.This study aimed to construct a radiomics-based nomogram for predicting LTPFS after RFA in CRC patients with lung metastases.Methods:This study retrospectively analyzed 172 CRC patients with 401 lung metastases admitted to Department of Interventional Radiology,Fudan University Shanghai Cancer Center from August 2016 to January 2019.This study was reviewed by the medical ethics committee of Fudan University Shanghai Cancer Center(ethics number:2402291-24).After augmentation of pre-ablation and immediate post-ablation computed tomography(CT)images,the target metastases and ablation regions were segmented manually to extract the radiomic features.Maximum relevance and minimum redundancy algorithm(MRMRA)and least absolute shrinkage and selection operator(LASSO)regression models were applied for feature selection.The clinical model,the radiomics model,and the fusion model were constructed based on the selected radiomic features and clinical variables screened by the multivariate analysis.The Harrell concordance index(C-index)and area under receiver operating characteristic(ROC)curves(AUC)were calculated to evaluate the prediction performance.Finally,the corresponding nomogram of the best model was drawn.Results:Among all the lung metastases,102(25.4%)had final recurrence,and 299(74.6%)had complete response(CR).The median follow-up time was 21 months(95%CI:19.466-22.534),and the LTPFS rates at 1,2,and 3 years after RFA were 76.5%(95%CI:72.0-80.4),72.1%(95%CI:66.6-76.9)and 69.9%(95%CI:64.0-75.1).In both the training and test dataset,the fusion model based on the final 12 radiomic features through the LASSO regression and 4 clinical variables screened by multivariate analysis achieved the highest AUC values for LTPFS,with C-index values of 0.890(95%CI:0.854-0.927)and 0.843(95%CI:0.768-0.916),respectively.Conclusion:The fusion model based on radiomic features and clinical variables is feasible for predicting LTPFS after RFA of CRC patients with lung metastases,whose performance is superior to the single radiomic and clinical model.At the same time,the nomogram of the fusion model can intuitively predict the prognosis of CRC patients with lung metastases after RFA,thus assisting clinicians in developing individualized follow-up review plans for patients and adjusting treatment strategies flexibly.

Objective:To assess the efficacy of butylphthalide and sodium chloride injection combined with interventional therapy in treatment of patients with acute anterior circulation macrovascular occlusive stroke.Methods:Clinical data of 92 patients with acute anterior circulation macrovascular occlusive stroke admitted to the Department of Neurology of Luoyang Central Hospital Affiliated to Zhengzhou University from February 2018 to June 2019 were retrospectively analyzed. Among them, 46 cases were treated with auxiliary arterial thrombolysis, aspiration thrombectomy or balloon dilatation (control group); and 46 patients were treated with butylphthalide and sodium chloride injection combined with Solitaire AB (S-AB) recyclable stent (study group). In control group the lesions were located in distal end internal carotid artery ( n=4), M1 segment of middle cerebral artery ( n=18) and M2 segment of middle cerebral artery ( n=24). In study group the lesions were located in the distal end of internal carotid artery ( n=5), M1 segment of middle cerebral artery ( n=15) and M2 segment of middle cerebral artery ( n=26). The cerebral infarction thrombolysis classification was used to evaluate vascular recanalization during operation. The neurological function of the patients before and 4 weeks after operation was evaluated with National Institutes of Health Stroke Scale Score (NIHSS); and the Disease Disability Scale Score (MRS) was also used to evaluate the neurological function before and 2 and 4 weeks after operation. Results:There was no significant difference in NIHSS score before treatment between control group and study group (22.8±5.2 vs. 23.4±4.1, t=0.614, P=0.54); after treatment the NIHSS of study group was significantly lower than that of control group (7.6±1.1 vs. 12.2±1.6, t=16.068, P<0.01). The success rate of vascular recanalization in the study group was higher than that of the control group [91%(42/46) vs. 76%(35/46), χ 2=3.903, P=0.04]. The short-term recanalization rate was 84% (39/46) and occlusion rate was 15%(7/46) in study group, while those in control group were 70% (32/46) and 30% (14/46), respectively (χ 2=6.566, P=0.01; χ 2=6.566, P=0.01) . MRS scores at 2 and 4 weeks after operation in the study group (5.51±0.34, 2.39±0.47) were better than those in the control group (6.87±0.46, 3.26±0.39; t=16.125, 9.661, all P<0.01) . Conclusion:Butylphthalide and sodium chloride injection combined with S-AB recyclable stent can enhance the nerve function and improve the hemagglutination mechanism in patients with acute anterior circulation macrovascular occlusive stroke and also significantly improve the vascular recanalization rate.

Objective Analyze the effect of emergency thrombolytic therapy on door to needle time (DNT) in patients with acute ischemic stroke (AIS) and effect.Method Selected 182 cases of AIS patients underwent intravenous thrombolysis at the First Hospital of Qinhuangdao from May 2015 to June 2017.Thrombolytic therapy group (83 cases),for the May 2015-May 2016 after neurological consultation intravenous thrombolysis patients;Emergency thrombolytic group(99 cases),for the June 2016-June 2017 emergency thrombolysis group Emergency Department of intravenous thrombolysis patients.Compare the two groups of DNT,thrombolytic therapy 24 h symptomatic hemorrhage conversion rate,Thrombolysis 24 h,7 dNIHSS score,7 dthrombolysis and 3 months thrombolysis and thrombolysis 3 months improved Rankin score (mRs).Results There was no significant difference in baseline characteristics between the two groups (P＞0.05).Compared with the consultation group,the DNT[(69.77±11.66)min vs (80.12±15.49) min,t=5.745,P ＜ 0.01] of emergency thrombolytic group was significantly shortened,and the good score[39(39.4％) vs 21(25.3％),x2=4.272,P=0.039] at 3 months after treatment was significantly higher (P＜0.05);Treatment of 24 h intracranial hemorrhage conversion rate[12(12.12％) vs 5(6.02％),x2=1.982,P=0.159]、Treatment 7d mortality rate [10(10.10％) vs 6(7.22％),x2=0.464,P=0.496],3 months mortality rate [14(14.14％) vs 11 (13.25％),x2=0.030,P=0.862]、There was no significant difference in the 24h effective rate [57(57.6％) vs 53(63.8％),x2=0.745,P=0.388] and 7d effective rate [50(50.5％) vs 46(55.4％),x2=0.438,P0.508] after treatment (P＞0.05).Conclusions The emergency thrombolytic model can shorten the DNT of rt-PA intravenous thrombolysis in patients with AIS.The safety and efficacy of DNT are not different from the neurological consultation mode,and can improve the good prognosis rate.

Objective To evaluate the efficacy of zero ischemia index (ZⅡ) in predicting the complexity and perioperative outcomes of off-clamp nephron-sparing surgery (NSS).Methods The patients between June 2016 and June 2017 in our institution who underwent off-clamp NSS were prospectively evaluated.ZⅡ was defined as the product of the tumor diameter and depth within renal parenchyma.The ZⅡ ＞6 defined as higher risk while ZⅡ ≤ 6 defined as low risk.The operating time,estimated blood loss,hospital stay,drainage,and complication rate were analyzed.Results There were 35 males and 10 females with average age of 42 y(range 23-76y).Mean tumor size was 2.4 cm (range 0.8-4.2 cm).Mini-flank approach open NSS was performed in 33 cases and laparoscopic NSS was performed in 12 cases.Off-clamp NSS was successfully performed in 44 patients except for renal artery occlusion in 1 case.Mean operative time was (95.0± 17.5) min (range 50-150 min);The average estimated blood loss was (152.4 ± 134.2) ml (range 20-600 ml);Mean postoperative drainage was (97.3 ± 59.7) ml (range 50-300 md);Mean postoperative hospital stay was (6.1 ± 1.3) d (range 5-8 d).Not severe post operative complication was observed.There were 37 patients in low risk group and 8 patients in high risk group.Operating time was significantly longer in high risk group [(118.8 ± 14.6 min) vs.(89.9±13.4) min,P＜0.01].EBL [(375.0±158.1) ml vs.(104.3 ±61.4) ml,P＜0.01] and drainage [(161.2±91.3)ml vs.(83.5 ±40.4)ml,P ＜ 0.01] were also significantly higher in high risk group.But there was no significant difference in hospital stay between two groups.The postoperative pathology indicated that 35 cases of clear cell carcinomas,2 cases of chromophobe renal cell carcinomas,one case of papillary carcinoma and seven cases of angiomyolipomas.Conclusions The ZⅡ is a novel and effective measurable criterion which can help predict the risk of perioperative outcomes of off-clamp NSS.ZⅡ =6 is established as a preliminary threshold for patient selection of off-clamp NSS.

Objective To compare the osteogenesis effect of platelet-rich fibrin (PRF) and platelet-rich plasma (PRP) and investigate the methods of repairing bone defect with PRF.Methods Four defects measuring 7 mm in diameter were made in the parietal bone of 16 New Zealand white rabbits.The defects named A,B,C,and D and were filled with PRF,PRF-mixed Bio-Oss (BO),PRP-mixed BO,and PRP separately.Every four rabbits were sacrificed at postoperative 2,4,8,and 12 weeks and defects were examined grossly,radiographically,and histologically.Besides,bone mineral density and bone trabecular area were determined and expressed as gray-scale values.Results Newly regenerated bone appeared at all defect areas at postoperative 2 weeks.Thereafter,more bone formations were observed over time and area B demonstrated the best bone healing followed by area C,A,and D in succession.Bone trabecular area in areas A,B,C,and D was 10.95 ± 0.58,15.45 ± 0.79,10.22 ± 0.43,and 6.58 ± 0.64 at postoperative 2 weeks with significant differences in pair comparison (F =22.869,P ＜0.01),followed by some increase at postoperative 4 and 8 weeks.Whereas,bone trabecular area in areas A,B,C,and D increased largely at postoperative 12 weeks (35.09 ± 0.58,59.44 ± 0.60,50.75 ± 1.56,and 30.94 ± 1.19) and showed significant difference when compared in a pair (F =1 002.904,P ＜ O.01).Conclusion PRF is superior to PRP in promoting bone formation,but a much better effect of PRF/BO composite is observed in bone repair.
