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 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 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 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.

The Ly-6 and uPAR (LU) domain-containing proteins represent a large family of cell-surface markers. In particular, mouse Ly-6A/Sca-1 is a widely used marker for various stem cells; however, its human ortholog is missing. In this study, based on a systematic survey and comparative genomic study of mouse and human LU domain-containing proteins, we identified a previously unannotated human gene encoding the candidate ortholog of mouse Ly-6A/Sca-1. This gene, hereby named LY6A, reversely overlaps with a lncRNA gene in the majority of exonic sequences. We found that LY6A is aberrantly expressed in pituitary tumors, but not in normal pituitary tissues, and may contribute to tumorigenesis. Similar to mouse Ly-6A/Sca-1, human LY6A is also upregulated by interferon, suggesting a conserved transcriptional regulatory mechanism between humans and mice. We cloned the full-length LY6A cDNA, whose encoded protein sequence, domain architecture, and exon-intron structures are all well conserved with mouse Ly-6A/Sca-1. Ectopic expression of the LY6A protein in cells demonstrates that it acts the same as mouse Ly-6A/Sca-1 in their processing and glycosylphosphatidylinositol anchoring to the cell membrane. Collectively, these studies unveil a novel human gene encoding a candidate biomarker and provide an interesting model gene for studying gene regulatory and evolutionary mechanisms.

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative pulmonary function in the patients undergoing robot-assisted radical resection of colon cancer.Method:Ninety-four patients of either sex, aged 50-80 yr, with body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, with ARISCAT grade of medium risk, undergoing elective robot-assisted radical resection of colon cancer, were enrolled in this study. The patients were divided into TEAS group (group T, n=47) and sham-TEAS group (group S, n=47) using a random number table method. In group T, patients received 30 min of TEAS at Hegu (LI4), Quchi (LI11), Zusanli (ST36) and Feishu (BL13) between 5: 00 and 7: 00 a. m. from 1st day before operation to 3rd day after operation, with disperse-dense wave 2/100 Hz, and the stimulation intensity was the maximum intensity that the patient could tolerate. Patients in group S were also connected to the device without electrical stimulation. Both groups adopted lung-protective ventilation strategy during operation. The oxygenation index was calculated at the time of entering the operating room (T 0), 5 min after anesthesia induction (T 1), 5 min of pneumoperitoneum (T 2), 5 min after changing to Trendelenburg position (T 3) and immediately after the end of pneumoperitoneum (T 4). Peak airway pressure, plateau airway pressure, driving pressure and dynamic lung compliance were recorded at T 0-T 4. The serum concentration of lung Clara cell 16 kDa protein was recorded using enzyme-linked immunosorbent assay at T 0, T 4 and 2 h after extubation (T 5). On 1 day before operation and 1, 3 and 7 days after operation, the forced expiratory volume in the first second (FEV 1) and forced vital capacity (FVC) were measured, and the FEV 1/FVC was calculated, and the concentrations of serum tumor necrosis factor-alpha, interleukin-6 and cardiopulmonary resuscitation were simultaneously determined using enzyme-linked immunosorbent assay. The occurrence of pulmonary complications within 7 days after operation was recorded. Results:There was no significant difference in pH values, PaCO 2, oxygenation index, peak airway pressure, plateau airway pressure, driving pressure, and dynamic lung compliance at each time point between the two groups ( P>0.05). Compared with S group, the serum Clara cell 16 kDa protein concentrations were significantly decreased at T 5, FEV 1 and FVC were increased at 3 and 7 days after operation, the serum tumor necrosis factor-alpha, interleukin-6 and cardiopulmonary resuscitation concentrations were decreased at 1, 3 and 7 days after operation, the incidence of unexpected oxygen supply and total incidence of postoperative pulmonary complications were decreased ( P<0.05), and no significant change was found in FEV 1/FVC at each time point in T group ( P>0.05). Conclusions:TEAS can improve lung function in the patients undergoing robot-assisted radical resection of colon cancer.

OBJECTIVE To develop a whole-process intelligent model of pharmaceutical care for peritoneal dialysis （PD） patients， and to provide a reference for clinical pharmacists to provide standardized PD pharmaceutical care. METHODS The pharmaceutical care mode of PD patients at home and abroad was investigated and analyzed. Based on the actual situation of the First Affiliated Hospital of Soochow University （hereinafter referred to as “our hospital”）， with “home→PD center outpatient→ inpatient department” as the main node， the recycling process of medication reconciliation was optimized. The whole-process intelligent pharmaceutical care model of PD was illustrated by improving the Chinese version of the drug-related problems （DRPs） classification tool， developing the corresponding pharmaceutical care process， and presenting specific cases. RESULTS Based on the medication therapy management （MTM） platform， our hospital had built a closed-loop PD whole-process intelligent pharmaceutical care model of “in-hospital pharmaceutical care （building document）-PD outpatient MTM-home pharmaceutical care （online App management）”. A “double cycle” workflow of “admission→discharge→outpatient” medication reconciliation cycle and “discovery-analysis-intervention-follow-up-record-evaluation” DRPs cycle was formed. CONCLUSIONS The establishment of the whole-process intelligent pharmaceutical care model for PD in our hospital provides experience for standardizing pharmaceutical care for PD patients， and can reduce DRPs.

Objective To observe the therapeutic effect of endovascular embolization for perimedullary arteriovenous fistula(PMAVF).Methods Data of 8 PMAVF patients who underwent endovascular embolization were retrospectively analyzed.Findings of digital subtraction angiography(DSA)immediately and 6 months after treatment were reviewed,and the modified Aminoff-Logue score(mALS)was compared before and 6 months after treatment.Results Among 8 cases of PMAVF,there were 2 cases of type Ⅰ,5 cases of type Ⅱand 1 case of type Ⅲ,among them 3 were treated with Onyx glue while 5 with Glubrane glue.The immediate DSA results after treatment showed complete embolization of the fistula in all 8 cases,while those 6 months after treatment showed no recurrence.One case recovered and the other 7 cases improved,and mALS(2.25±2.12)6 months after treatment was lower than that(5.50±2.39)before treatment(P＜0.05).Conclusion Endovascular embolization could safely and effectively treat PMAVF.
