Objective To investigate the clinical characteristics,imaging features,laboratory test results,and prognosis of children with acute lymphoblast leukemia(ALL)complicated by cerebral hemorrhage.Methods A retrospective analysis was conducted on the clinical data of 20 children with ALL complicated by cerebral hemor-rhage admitted to the Department of Hematology,Children's Hospital of Soochow University from June 20,2014 to June 20,2024.Results The clinical manifestation of the 20 children with ALL complicated by cerebral hemorrhage were complex and diverse,with disturbance of consciousness being the most common initial symptom.The prognosis varied depending on the size and location of the hematoma and whether it ruptured into the ventricle.Among the 20 cases,14(70％)demonstrated improvement in intracranial lesions,with 8(40％)cases exhibiting substantial lesion absorption and favorable prognosis.Six cases(30％)showed improvement in intracranial lesions but not complete resolution,three cases developed focal encephalomalacia,two cases had residual symptomatic epi-lepsy and one had residual right-sided hemiplegia.Furthermore,three(15％)cases suffered recurrent cerebral hemorrhages at distinct locations from the initial event following improvement of the primary hemorrhage,and 3(15％)cases led to mortality.Conclusions Neurological symptoms in children with acute lymphoblast leukemia(ALL)complicated by cerebral hemorrhage are diverse and often atypical.Timely cranial imaging and laboratory tests are necessary,while surgical intervention and platelet transfusion should be a prudential consideration.

Objective To compare the efficacy of stenting in the treatment of idiopathic intracranial hypertension(IIH)complicated by different types of venous sinus stenosis(VSS).Methods The clinical data of 48 patients with IIH complicated by VSS,who received stenting therapy at the First Affiliated Hospital of Zhengzhou University of China from January 2019 to September 2023,were retrospectively analyzed.According to the type of VSS,the patients were divided into intrinsic stenosis group(n=20)and the extrinsic stenosis group(n=28).The improvement of symptoms,Frisén grade of papilledema,lumbar puncture opening pressure(LPOP),trans-stenosis pressure gradient(△P)of VSS,and surgery-related complications were compared between the two groups.Results The mean age of the patients in the intrinsic stenosis group was greater than that of the patients in the extrinsic stenosis group(41.60 years vs.35.25 years,P=0.049).The length of the narrowed segment in the extrinsic stenosis group was 22.5 mm,which was significantly longer than 19.0 mm in the intrinsic stenosis group(P=0.007).The postoperative Frisén grade of papilledema in the extrinsic stenosis group was obviously lower than that in the intrinsic stenosis group(P=0.037).No statistically significant differences in the other clinical data existed between the two groups(all P＞0.05).After stenting,all of the median △P,mean LPOP,and median Frisén grade of papilledema were decreased significantly when compared with their preoperative values(all P＜0.001),and the postoperative 3-day median Frisén grade of papilledema in the extrinsic stenosis group was much lower(P=0.037).The patients were followed up for one year,the clinical symptoms of the patients in both groups were improved to varying degrees.At the time of discharge,the proportion of patients having no symptoms of papilledema in the extrinsic stenosis group was 57.1％,which was higher than 22.2％in the intrinsic stenosis group(P=0.049),and no statistically significant differences in the improvements of other symptoms existed between the two groups(all P＞0.05).There was no significant difference in the incidence of complications between the two groups(P=0.563).Conclusion Venous sinus stenting can effectively treat patients with IIH complicated by different types of VSS.

Objective To compare the clinical efficacy of medication and stenting in treating patients with idiopathic intracranial hypertension complicated by venous sinus stenosis.Methods The clinical data of 74 patients with idiopathic intracranial hypertension complicated by venous sinus stenosis,who were admitted to the First Affiliated Hospital of Zhengzhou University of China from January 2020 to June 2023,were retrospectively analyzed.The patients were divided into medication group(n=35,receiving drug therapy)and stenting group(n=39,receiving stent implantation therapy).Before and after treatment,lumbar puncture and fundus examinations were performed,and the postoperative improvements in intracranial pressure and papillary oedema were evaluated.The changes in the median papillary oedema Frisén grade and the average opening pressure of lumbar puncture were compared between the two groups during hospitalization period.The improvement degrees of the clinical symptoms determined at discharge,as well as at the 6 months and 12 months after discharge were compared between the two groups.The incidence of complications during the follow-up period in the two groups was recorded.Results The time interval from onset to treatment in the stenting group was longer than that in the medication group(2 months vs.one month,P=0.021),and the differences in the other baseline data between the two groups were not statistically significant(all P＞0.05).After treatment,different degrees of improvement were obtained in both groups(all P＞0.05).At the time of discharge,the degree of median papillary oedema in the stenting group was Frisén grade I,which was lower than Frisén grade Ⅱ in the medication group(P=0.011);the average opening pressure of lumbar puncture in the stenting group was 205.26 mm H2O,which was lower than 248.14 mm H2O in the medication group(P=0.002).The proportions of patients having no symptom or showing symptom improvement in the stenting group and in the medication group at the time of discharge were 74.4％and 45.7％respectively(P=0.017),which at the time of 6 months after discharge were 84.6％and 48.6％respectively(P=0.001)and at the time of 12 months after discharge were 87.2％and 57.1％respectively(P=0.004).No statistically significant difference in the incidence of complications existed between the two groups(10.3％and 8.6％respectively,P=1.000).Conclusion For the treatment of patients with idiopathic intracranial hypertension complicated by venous sinus stenosis,stent implantation therapy is superior to medication therapy in quickly and effectively relieving papillary oedema,decreasing lumbar puncture opening pressure,and improving their corresponding symptoms and signs,with satisfactory patient's prognosis and clinical safety.

Objective To summarize the characteristics of chemotherapy-induced peripheral neuropathy(CIPN)in children with acute B-lymphoblast leukemia(B-ALL)and to identify the influencing factors and prognosis of CIPN.Methods The clinical data of 60 children with B-ALL admitted to the 29th Ward of the Department of Hematology and Oncology,Children's Hospital Affiliated to Soochow University from June 2020 to December 2023 who received chemotherapy and had finished chemotherapy for 6 months were retrospectively reviewed.Results There were 37 cases of B-ALL combined with CIPN;the incidence of CIPN was 61.7% .Increasing age of onset was a risk factor for CIPN in children[OR=1.209,95% CI(1.023-1.428),P=0.026]with the highest incidence of sensory nerve dysfunction(78.4% ).Electromyography indicated that B-ALL combined with CIPN was multiple peripheral neurogenic lesions with certain reversibility.In the induction stage of chemotherapy,13 cases(35.1% )showed CIPN,accounting for the highest proportion.The CIPN improvement rate 6 months after chemotherapy was 67.6%,the age of onset[OR=2.418,95% CI(0.212-2.106),P=0.018]and the severity of CIPN[OR=203.394,95% CI(2.29-18 065.04). P=0.02]were risk factors for poor prognosis of children with CIPN.The older the age of onset was,the higher the severity of CIPN and worse prognosis were found.Conclusions Children with B-ALL complicated with CIPN are reversible multiple peripheral nerve lesions,and the occurrence and outcome of CIPN is potentially related to individual differences of children.

Objective To explore the diagnostic value of serum interleukin(IL)-1β and IL-18 levels in the severity of pneumonia.Methods A total of 200 patients with pneumonia treated in the Affiliated Yongchuan Hospital of Chongqing Medical University from January to December 2022 were retrospectively selected and divided into mild group(n=100)and severe group(n=100)according to the severity of pneumonia,and 100 healthy people who underwent physical examination in our hospital were included as normal group.The general clinical data,hematology index,fever peak,cough,rales and complications were analyzed.Propensity score matching was performed for patients in mild group and severe group,and the receiver operating characteristic(ROC)curve was used to calculate the diagnostic efficacy of IL-1β and IL-18 before and after matching.Results There were statistically significant differences in IL-1β and IL-18 levels among the three groups(P<0.05),and severe group>mild group>normal group.The cut-off values of IL-1β and IL-18 in the diagnosis of severe pneumonia before matching were 12.169pg/ml and 194.535pg/ml,respectively.IL-1β was more effective than IL-18 in the diagnosis of severe pneumonia(0.490 vs.0.380).The cut-off values of IL-1β and IL-18 in the diagnosis of severe pneumonia after matching were 10.542pg/ml and 191.372pg/ml,respectively.IL-1β was more effective than IL-18 in the diagnosis of severe pneumonia(0.493 vs.0.360).Conclusion IL-1β and IL-18 increase with the severity of pneumonia and have high diagnostic value for severe pneumonia.

Objective To compare therapeutic efficacy of anticoagulation alone and combining with intervention for treating severe cerebral venous thrombosis(CVT).Methods Data of 65 severe CVT patients were retrospectively analyzed.The patients were divided into anticoagulation group(n=32)or combined group(n=33)according to therapeutic methods.The modified Rankin scale(mRS)score at admission and discharge,the prognosis of patients,vascular recanalization rate as well as incidence of complications during follow-up period were compared between groups.Results No significant difference of mRS scores at admission was found between groups(P＞0.05),while mRS scores of combined group were lower than of anticoagulation group at discharge(P＜0.05).The rate of good prognosis at discharge(84.85%vs.59.38%),6 months after discharge(87.88%vs.65.63%)and 12 months after discharge(93.94%vs.75.00%)in combined group were all higher than those in anticoagulation group(all P＜0.05).The vascular recanalization rate in combined group was higher than that in anticoagulant group(100%vs.75.00%,P＜0.05).At the end of follow-up,no significant difference of complication incidence was found between groups(15.15%vs.18.75%,P＞0.05).Conclusion For patients with severe CVT,anticoagulation combined with interventional therapy could significantly alleviate clinical symptoms and improve prognosis compared with anticoagulation alone.

Objective To observe the value of stent implantation for treating idiopathic intracranial hypertension(IIH)complicated with venous sinus stenosis(VSS).Methods Data of 54 patients with IIH complicated with VSS who underwent stent implantation were retrospectively analyzed.The papillary edema grade,lumbar puncture-opening pressure(LP-OP)and trans-stenotic pressure gradient of venous sinus(ΔP)before and after stent implantation were compared,and the symptom improvement and treatment-related complications during the follow-up period were recorded.Results Totally 60 stents were successfully implanted in 54 patients.Before stent implantation,the papillary edema grade was 3(3,3),LP-OP was(391.39±92.62)mmH2O and the ΔP was 18.50(15.00,25.00)mmHg,which decreased to 1(0,1),(208.80±62.31)mmH2O and 1.25(0.88,2.55)mmHg after stent implantation,respectively,all with significant differences(all P＜0.001).Clinical symptoms improved after stent implantation in all 54 patients.At the end of follow-up,disappearance of headache,papillary edema,visual disorder,abducent nerve paralysis and tinnitus were noticed in 30(30/37,81.08%),38(38/45,84.44%),41(41/45,91.11%),8(8/10,80.00%)and 9 cases(9/10,90.00%),respectively.Treatment-related complications occurred in 4 cases(4/54,7.41%),all improved after intervention.Conclusion Stent implantation was effective and safe for treating IIH complicated with VSS.

Objective:To evaluate the effect of emodin on liver injury in a mouse model of intestinal ischemia-reperfusion (I/R) and the role of heme oxygenase-1-mediated autophagy.Methods:Twenty-four SPF-grade healthy male C57BL/6 mice, aged 6-8 weeks, weighing 18-22 g, were divided into 4 groups ( n=6 each) using a random number table method: sham operation group (Sham group), I/R group, emodin group (E group) and emodin plus HO-1 inhibitor Zinc Protoporphyrin Ⅸ (ZnPP) group (ES group). The intestinal I/R injury model was established by clamping the superior mesenteric artery for 45 min followed by 120 min of reperfusion. Emodin 40 mg/kg dissolved in 5% methylcellulose sodium was given by gastric gavage once a day for 5 days before ischemia in E group. Emodin 40 mg/kg dissolved in 5% methylcellulose sodium was given by gastric gavage once a day for 5 days before intestinal I/R, and ZnPP 7.5 mg/kg was injected via the tail vein at 12 h before ischemia in ES group. Orbital venous blood samples were collected at the end of reperfusion for determination of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) concentrations. Then the mice were sacrificed, and liver tissues were obtained for microscopic examination of the pathological changes (after HE staining) and for determination of the activity of superoxide dismutase (SOD), content of malondialdehyde (MDA), expression of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) mRNA (by fluorescent quantitative polymerase chain reaction), the expression of HO-1, autophagy-related protein Beclin1 and microtubule-associated protein 1 light chain 3 (LC3) (by Western blot). The LC3-Ⅱ/Ⅰ ratio was calculated. Results:Compared with Sham group, the activity of SOD was significantly decreased, the content of MDA and serum ALT and AST concentrations were increased, the expression of IL-6 and TNF-α mRNA and HO-1 was up-regulated, the expression of Beclin1 was down-regulated, the LC3-Ⅱ/Ⅰ ratio was decreased ( P<0.05), and the pathological changes of liver tissues were found in I/R group. Compared with I/R group, the activity of SOD was significantly increased, the content of MDA and serum ALT and AST concentrations were decreased, the expression of IL-6 and TNF-α mRNA was down-regulated, the expression of HO-1 and Beclin1 was up-regulated, the LC3-Ⅱ/Ⅰ ratio was increased ( P<0.05), and the pathological changes of liver tissues were significantly attenuated in E group ( P<0.05). Compared with E group, the activity of SOD was significantly decreased, the content of MDA and serum ALT and AST concentrations were increased, the expression of IL-6 and TNF-α mRNA was up-regulated, the expression of HO-1 and Beclin1 was down-regulated, the LC3-Ⅱ/Ⅰ ratio was decreased ( P<0.05), and the pathological changes of liver tissues were aggravated in ES group. Conclusions:Emodin can alleviate liver injury induced by intestinal I/R in mice, and the mechanism may be related to the activation of HO-1-mediated autophagy.

OBJECTIVE: To investigate the incidence and potential risk factors associated with postoperative spinal epidural hematoma (SEH) following anterior cervical spine surgery (ACSS). METHODS: A retrospective analysis was conducted on the clinical data of patients who underwent ACSS for cervical spondylosis at Peking University Third Hospital between March 2013 and February 2022. Patients who developed postoperative SEH were categorized as the SEH group, while those in the cohort without SEH were randomly selected as the non-SEH group by individually matching with the same operator, same gender, same surgery year, and similar age (±5 years) at a ratio of 4 ∶ 1. The general condition, preoperative comorbidities, anticoagulant or antiplatelet therapy, preoperative coagulation and platelet counts, American society of Anesthesiologists physical status classification, cervical spondylosis classification, preoperative modified Japanese Orthopaedic Society score and cervical disability index score, surgical modality, surgical segment levels, ossification of the posterior longitudinal ligament among the surgical level, surgery duration, estimated blood loss, postoperative drainage volume, preoperative mean arterial pressure, mean arterial pressure during postoperative awakening periods, hospital stay and hospitalization cost were compared between the two groups. A bivariate Logistic regression model was applied to screen out the independent risk factors and calculate the odds ratios of indicators associated with SEH. Receiver operating characteristic curve and area under the curve (AUC) were used to describe the discrimination ability of the indicators. RESULTS: A total of 85 patients were enrolled in the study, including 17 patients in the SEH group and 68 patients in the non-SEH group. Seventeen patients with SEH underwent hematoma evacuation, and all of them were successfully treated and discharged from the hospital. Corpectomy (OR=7.247; 95%CI: 1.962-26.766; P=0.003) and the highest mean arterial pressure during awakening (OR=1.056; 95%CI: 1.002-1.113; P=0.043) were independent risk factors for SEH. The AUC values were 0.713 (95%CI: 0.578-0.848) and 0.665 (95%CI: 0.51-0.82) respectively. The patients with SEH had longer hospital stays (P < 0.001) and greater hospitalization costs (P=0.035). CONCLUSION Corpectomy and elevated maximum mean arterial pressure during awakening are independent risk factors for the development of postoperative SEH following ACSS. High-risk patients should be closely monitored during the perioperative period.

Objective:To investigate the surgical efficacy and prognosis influencing factors of hilar cholangiocarcinoma based on multidisciplinary diagnosis and treatment.Methods:The retrospective cohort study was conducted. The clinicopathological data of 91 patients with hilar cholangiocarcinoma who underwent surgery in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from April 2004 to April 2021 were collected. There were 59 males and 32 females, aged (61±10)years. Patients who were admitted from April 2004 to March 2014 underwent traditional surgical diagnosis and treatment, and patients who were admitted from April 2014 to April 2021 underwent multidisciplinary diagnosis and treatment. Observation indica-tors: (1) surgical situations; (2) postoperative situations; (3) postoperative pathological examina-tions; (4) postoperative prognosis analysis; (5) influencing factors of postoperative prognosis. Follow-up was conducted using telephone interview and outpatient examination. Patients were followed up once every 6 months after surgery to detect survival. The follow-up was up to April 2023. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Comparison of ordinal data was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Kaplan-Meier method was used to draw survival curve and calculate survival rate. The Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard model. Results:(1) Surgical situations. Of the 91 patients, there were 65 cases receiving hemi- or expanded hemi-hepatectomy, 13 cases receiving tri-hepatectomy, 9 cases receiving partial hepatectomy, 4 cases receiving extrahepatic bile duct resection. There were 24 cases receiving combined vein resection and reconstruction, 8 cases receiving combined pancreaticoduodenectomy, 6 cases receiving com-bined hepatic artery resection and reconstruction, including 24 cases receiving extended radical surgery (tri-hepatectomy, hepatic artery resection and reconstruction, hepatopancreaticoduodenec-tomy). The operation time, volume of intraoperative blood loss and intraoperative blood transfusion rate of 91 patients was (590±124)minutes, 800(range, 500?1 200)mL and 75.8%(69/91), respectively. Of the 91 patients, cases receiving extended radical surgery, the volume of intraoperative blood loss were 4, 650(range, 300?1 000)mL in the 31 patients who were admitted from April 2004 to March 2014, versus 20, 875 (range, 500?1 375)mL in the 60 patients who were admitted from April 2014 to April 2021, showing significant differences between them ( χ2=4.39, Z=0.31, P<0.05). (2) Post-operative situations. The postoperative duration of hospital stay and cases with postoperative infectious complications were (27±17)days and 50 in the 91 patients. Cases with abdominal infection, cases with infection of incision, cases with bacteremia and cases with pulmonary infection were 43, 7, 5, 8 in the 91 patients. One patient might have multiple infectious complications. Cases with bile leakage, cases with delayed gastric emptying, cases with chylous leakage, cases with liver failure, cases with pancreatic fistula, cases with intraperitoneal hemorrhage, cases with reoperation, cases dead during the postoperative 90 days were 30, 9, 9, 6, 5, 3, 6, 3 in the 91 patients. Cases with abdominal infection was 10 in the 31 patients who were admitted from April 2004 to March 2014, versus 33 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=4.24, P<0.05). Cases dead during the postoperative 90 days was 3 in the 31 patients who were admitted from April 2004 to March 2014, versus 0 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( P<0.05). (3) Post-operative pathological examinations. Of the 91 patients, cases with Bismuth type as type Ⅰ?Ⅱ, type Ⅲ, type Ⅳ, cases with T staging as Tis stage, T1 stage, T2a?2b stage, T3 stage, T4 stage, cases with N staging as N0 stage, N1 stage, N2 stage, cases with M staging as M0 stage, M1 stage, cases with TNM staging as 0 stage, Ⅰ stage, Ⅱ stage, Ⅲ stage, ⅣA stage, ⅣB stage, cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 46, 30, 1, 9, 25, 30, 26, 49, 36, 6, 85, 6, 1, 7, 13, 58, 6, 6, 63, 28. Cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 16 in the 31 patients who were admitted from April 2004 to March 2014, versus 48, 12 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=9.59, P<0.05). (4) Postoperative prognosis analysis. Of the 91 patients, 3 cases who died within 90 days after surgery were excluded, and the 5-year overall survival rate and median overall survival time of the rest of 88 cases were 44.7% and 55 months. The 5-year overall survival rate was 33.5% in the 28 patients who were admitted from April 2004 to March 2014, versus 50.4% in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=5.31, P<0.05). Results of further analysis showed that the corresponding 5-year overall survival rate of cases without lymph node metastasis was 43.8% in the 16 patients who were admitted from April 2004 to March 2014, versus 61.6% in the 31 patients who were admitted from April 2014 to April 2021. There was a significant difference in the 5-year overall survival rate between these patients without lymph node metastasis ( χ2=3.98, P<0.05). The corresponding 5-year overall survival rate of cases with lymph node metastasis was 18.5% in the 12 patients who were admitted from April 2004 to March 2014, versus 37.7% in the 29 patients who were admitted from April 2014 to April 2021. There was no significant difference in the 5-year overall survival rate between these patients with lymph node metastasis ( χ2=2.25, P>0.05). (5) Influencing factors of postoperative prognosis. Results of multivariate analysis showed that poorly differentiated tumor and R 1 or R 2 resection were inde-pendent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma ( hazard ratio=2.62, 2.71, 95% confidence interval as 1.30?5.29, 1.30?5.69, P<0.05). Conclusions:Compared with traditional surgical diagnosis and treatment, treatment of hilar cholangiocarcinoma based on multidisciplinary diagnosis and treatment can expand surgical indications, reduce proportion of dead patients within 90 days after surgery, improve proportation of radical resection and long-term survival rate. Poorly differentiated tumor and R 1 or R 2 resection are independent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma.
