ObjectiveTo investigate the therapeutic effect and mechanism of modified Chunzetang on bladder fibrosis and detrusor function in rats with neurogenic bladder urinary retention induced by spinal cord injury. MethodsIn this study， an improved Hassan Shaker spinal cord transection method was used to establish a model of neurogenic bladder urinary retention induced by spinal cord injury， and rats with a spinal cord injury behavior score of 0 were selected for follow-up experiments. The selected rats were randomly divided into a model group （normal saline gavage）， low-dose traditional Chinese medicine （TCM） group （gavage of 14.4 g·kg^-1 modified Chunzetang）， high-dose TCM group （gavage of 28.8 g·kg^-1 modified Chunzetang）， positive drug group ［intraperitoneal injection of 0.05 g·kg^-1 nuclear transcription factor-κB （NF-κB） inhibitor pyrrolidine dithiocarbamate （PDTC）］， and combination group （intraperitoneal injection of 0.05 g·kg^-1 PDTC + gavage of 28.8 g·kg^-1 modified Chunzetang）. The rats in these groups were administrated with corresponding drugs once a day for four weeks. The BL-420s biofunction acquisition system was used in the experiment to calculate the urodynamic indexes， and the isolated bladder was quickly weighed. The detrusor traction experiment was used to record the minimum bladder contraction tension and frequency in each group. The pathological morphology and tissue fibrosis of detrusor in each group observed by Hematoxycin-eosin （HE） staining and Masson staining were compared. The expression level of α-smooth muscle actin （α-SMA） was detected by immunohistochemistry. Western blot was used to detect the protein expression of NF-κB p65， nuclear transcription factor-κB suppressor protein α （IκBα）， transforming growth factor-β₁ （TGF-β₁）， type Ⅰ collagen （ColⅠ）， and type Ⅲ collagen （ColⅢ） in bladder tissue of rats in each group. Enzyme-linked immunosorbent assay （ELISA） was used to detect the changes in serum levels of IL-6， IL-1β， and TNF-α. ResultsCompared with that in the sham operation group， the pressure at the urinary leakage point in the model group decreased （P<0.01）， and the bladder mass， bladder contractile tension， maximum bladder capacity， and bladder compliance increased （P<0.05，P<0.01）. HE staining showed that the arrangement of bladder epithelial cells was disordered， and the pathological manifestations such as mucosa and myometria neutrophil infiltration were obvious. The lamina propria structure was destroyed， and the muscle fiber arrangement was disordered. The interstitial widening and tissue edema were obvious. Masson staining showed that the bladder wall of the model group had more collagen fiber deposition， and the degree of detrusor fibrosis was more severe. The content of detrusor in the visual field was reduced. At the same time， the protein expressions of NF-κB p65， TGF-β₁， IκBα， ColⅠ， and ColⅢ in bladder tissue of rats in the model group were significantly increased （P<0.01）， and the serum levels of IL-6， IL-1β， and TNF-α were significantly increased （P<0.05）. Compared with that in the model group， the pressure at the urinary leakage point in the modified Chunzetang and positive drug groups was increased （P<0.05）， and the wet bladder weight， minimum bladder contractile tension， maximum bladder capacity， and bladder compliance were restored （P<0.05， P<0.01）. HE and Masson showed that the bladder epithelial cells were relatively neatly arranged， and the structure of the bladder lamina propria was relatively stable. The detrusor bundles were arranged in an orderly manner， and the interstitium was narrow. The degree of tissue edema was relatively low， and the degree of bladder detrusor fibrosis in the modified Chunzetang and positive drug groups was reduced， while the degree of bladder detrusor fibrosis in the positive drug group and combination groups was not obvious. The results of Western blot showed that the expression of NF-κB p65， IκBα， TGF-β₁， ColⅠ， and ColⅢ in bladder tissue， as well as the serum levels of IL-6， IL-1β， and TNF-α in modified Chunzetang and positive drug groups were significantly lower， and the expression of bladder tissue-related proteins and the serum levels of IL-6， IL-1β， and TNF-α in the TCM groups decreased significantly with the increase in dose （P<0.05）. The results of immunohistochemistry suggested that modified Chunzetang could fully affect the expression of α-SMA in bladder tissue. ConclusionModified Chunzetang can inhibit collagen deposition in bladder tissue of rats with urinary retention induced by spinal cord injury， delay the occurrence and development of bladder fibrosis， and protect the normal contractile function of bladder detrusor， and its mechanism may be related to inhibiting the NF-κB/TGF-β₁ signaling pathway， reducing the production of NF-κB p65， IκBα， TGF-β₁， ColⅠ， ColⅢ， and other related proteins， and protecting the muscle strength of detrusor.

Objective: To explore the safety and feasibility of the disconnection of the left renal artery preferentially during robot-assisted inferior vena cava (IVC) thrombectomy for patients with left renal cell carcinoma and tumor emboli. Methods: Clinical data of 7 patients who underwent robot-assisted IVC thrombectomy and radical nephrectomy in the First Affiliated Hospital of Zhengzhou University during Dec.2021 and Oct.2024 were retrospectively analyzed.Thrombectomy was performed first，followed by nephrectomy. The “IVC-first, kidney-last”robotic technique was developed to minimize chances of IVC thrombus. When patients in left lateral decubitus position, the left renal artery was severed from the right side through the inferior vena cava and abdominal aorta. After removal of thrombus from IVC was completed, patients changed to the right lateral position to complete radical left nephrectomy. Results: Imaging examinations revealed that the median diameter of the renal cell carcinomas was 83(46-99) mm; the median length of the inferior vena cava cancerous emboli was 49(2-91) mm.According to the Mayo classification，the cancerous emboli were gradeⅠ in 2 cases，gradeⅡ in 4 cases，and grade Ⅲ in 1 case.All surgeries were successful.The median operation time was 248(201-331) minutes，blood loss 500(200-1000) mL，and 6 cases required intraoperative blood transfusion.The median time for transition into the intensive care unit was 1(1-4) days，and drainage tube removal 6(5-12) days.Serum creatinine increased significantly in 5 cases，4 of which returned to normal after 1 week，but 1 had renal insufficiency (creatinine 166 μmol/L).Chylous fistula occurred in 1 patient，and lower extremity venous thrombosis developed in 3 patients.Pathological examinations indicated 6 cases of renal cell carcinoma and 1 case of MiT family translocation renal cell carcinoma.During the median follow-up of 17(1-35) months，5 cases were tumor-free，while 2 had lung and retroperitoneal metastases.They received targeted therapy of axitinib combined immunotheraphy and lived with tumors. Conclusion: In the left lateral position for left renal cell carcinoma with cancerous emboli，robot-assisted laparoscopic thrombectomy by crossing the inferior vena cava and abdominal aorta and disconnecting the left renal artery first is safe and feasible.

Objective To evaluate the differential diagnostic value of synthetic magnetic resonance imaging(syMRI)and field of view optimized and constrained undistorted single shot diffusion weighted imaging(FOCUS DWI)in patient with breast imaging reporting and data system(BI-RADS)4 breast lesions.Methods A total of 68 patients who underwent breast MRI and were classified as BI-RADS category 4 were prospectively enrolled.Among them,there were 31 cases of benign lesions(benign group)and 37 cases of malignant lesions(malignant group).All patients underwent T1WI,T2WI,FOCUS DWI,dynamic contrast-enhanced magnetic resonance ima-ging(DCE-MRI)and syMRI.Two radiologists delineated the region of interest(ROI)on quantitative parameters images of syMRI and the apparent diffusion coefficient(ADC)images generated from FOCUS DWI and calculated T1,T2,proton density(PD)and ADC values,respectively.The thresholds and diagnostic efficacy of syMRI and FOCUS DWI parameters were evaluated by the receiver op-erating characteristic(ROC)curve.Logistic regression analysis was used to combine the parameters of the two sequences and evalu-ate the diagnostic efficacy.Results The T2,PD,and ADC values in the malignant group were significantly lower than those in the benign group(P＜0.05),but there were no statistically significant difference in T1 values between the groups(P＞0.05).T2 and ADC values could be used as important diagnostic indexes in patient with malignant lesions of BI-RADS 4 breast lesions,and the area under the curve(AUC)of T2 and ADC was 0.833 and 0.867,respec-tively.There was no significant difference in AUC of T2 and ADC between benign and malignant groups(Z=0.485,P=0.627).The AUC of T2 value combined with ADC value was 0.910,and the sensitivity and specificity was 90.3％and 89.2％,respectively.Conclusion T2 value of syMRI and ADC value of FOCUS DWI can be used as quantitative diagnostic indicators in patients with BI-RADS 4 breast lesions.The combination of T2 and ADC values can further improve the differential diagnosis efficiency.

Objective To investigate the predictive value of inflammatory cells and clinical features in the prognosis of immune checkpoint inhibitors (ICIs) treating non-small cell lung cancer (NSCLC).Methods The data of 163 cases of stage Ⅲ and Ⅳ NSCLC patients treated with the ICIs in this hospital from January 1,2017 to December 31,2022 were collected.The CT examination was conducted after 6-8 weeks treatment.The pa-tients were divided into the objective remission group[complete remission (CR)+partial remission (PR)]and non-objective remission group[stable disease (SD)+progressed disease (PD)],disease control group (CR+PR+SD) and non-disease control group (PD),persistent clinical benefit group (DCB) and non-DCB group.The differences in clinical features and inflammatory cells indicators were compared among the differ-ent groups.The receiver operating characteristic (ROC) curve was adopted to evaluate the predictive efficiency of the inflammatory cells indicators for DCB.The influencing factors analysis of progression free survival (PFS) time and overall survival (OS) time adopted the Cox regression analysis.Results The lymphocyte count (ALC) in the disease control group was higher than that in the non-disease control group.The neutro-phil to lymphocyte ratio (NLR),platelet-lymphocyte ratio (PLR) and mononuclear lymphocyte ratio (MLR) were lower than those in the non-disease control group.The proportions of squamous cell carcinoma,stage Ⅲ,ECOG score 0-1 point,adverse reactions in the DCB group were higher than those in the non-DCB group (P<0.05),the PLT count,NLR,PLR and MLR were lower than those in the non-DCB group (P<0.05). The ROC curve analysis results showed that PLT,NLR,PLR and MLR could serve as the indicators for pre-dicting DCB,the area under of ROC curve (AUC) was 0.633,0.602,0.635 and 0.604 respectively,the opti-mal cut off values were 187×109/L (P=0.004),5.0 (P=0.026),235 (P=0.003) and 0.35 (P=0.024) re-spectively.The multivariate Cox regression analysis showed that non-squamous carcinoma including adenocar-cinoma (HR=1.565,95％CI:1.057-2.316) and other pathologic types (HR=2.285,95％CI:1.326-3.936),ECOG score 2-3 points (HR=2.375,95％CI:1.652-3.415),AMC≥0.65×109/L (HR=1.847,95％CI:1.160-2.938) and PLR≥235 (HR=1.557,95％CI:1.016-2.386) were the independent risk factors for short PFS.The ECOG score 2-3 points (HR=4.615,95％CI:2.882-7.391),AMC≥0.65×109/L (HR=5.161,95％CI:2.984-8.925) and PLR ≥235 (HR=1.732,95％CI:1.059-2.833) were the independent risk fac-tors for short OS (P<0.05),and having adverse reactions (HR=0.472,95％CI:0.294-0.757) was the independ-ent protective factor for short OS (P<0.05).Conclusion Lower PLT,AMC,NLR,MLR and PLR,higher ALC,squamous cell carcinoma,TNM stage Ⅲ,ECOG score 0-1 point and immunotherapy related adverse reactions could prompt that the prognosis is good in ICIs treating advanced NSCLC.PLT,NLR,PLR and MLR could serve as the indicators for predicting DCB.

Multiple thrombosis in the coronary arteries need to be characterized by a thorough determination of the source of the thrombus to distinguish them as thrombosis or coronary embolism.This case was a 38-year-old male patient with chest pain and an electrocardiogram showing acute inferior wall and right ventricular myocardial infarction.Emergency coronary angiography showed thrombosis in the proximal middle of the left anterior descending artery,the opening of the first diagonal artery,and the middle of the right coronary artery,but no obvious stenosis was seen.Postoperative electrocardiogram showed acute inferior wall,right ventricular and anterior wall myocardial infarction,and intensive antithrombotic treatment was applied,elective re-examination of coronary angiography and intraluminal imaging showed mixed plaques and suspicious intimal dissection,indicating the possibility of thrombosis secondary to unstable plaque and coronary dissection,and intensive drug treatment was given.After discharge,the patient was stable during the regular follow-up visits.
