Objective To evaluate the postoperative analgesia efficacy and clinical safety of hydro-morphone patients-controlled intravenous analgesia(PCIA)in patients with scar pregnancy after auxiliary uterine artery embolization(UAE).Methods A total of 116 patients with scar pregnancy,who received auxiliary UAE at the Fuyang Municipal People's Hospital of China between January 2021 and September 2022,were enrolled in this study.According to the intravenous self-controlled analgesic drugs used after UAE,the patients were randomly and equally divided into observation group(n=58)and control group(n=58).Ten minutes before the procedure,intravenous injection of 2 mg hydromorphone(observation group)or 2 μg/kg sufentanyl(control group)was performed,and the PCIA pump was connected.In the observation group,the mixed solution of 10 mg hydromorphone+100 mg flurbiprofen axetil+100 mL saline was put in the analgesic pump,while in the control group,the mixed solution of 2 μg/kg sufentanyl+flurbiprofen axetil 100 mg+100 mL saline was put in the analgesic pump.The post-UAE 0.5-h,4-h,8-h,12-h,24-h and 48-h visual analogue scale(VAS)scores,the Bruggrmann comfort scale(BCS)scores,the number of pressing analgesic pump times within postoperative 48 hours,the used dosage of analgesic drugs,the adverse reactions,and the incidence of postoperative complications were recorded.Results The difference in the post-UAE 0.5-h VAS scores between the observation group and the control group was not statistically significant(P＞0.05),while the post-UAE 4-h,8-h,12-h,24-h and 48-h VAS scores in the observation group were significantly lower than those in the control group,and the differences were statistically significant(all P＜0.05).The post-UAE 0.5-h,4-h,8-h,12-h,24-h and 48-h BCS scores in the observation group were significantly higher than those in the control group,and the differences were statistically significant(all P＜0.05).The number of pressing analgesic pump times and the used dosage of analgesic drugs within postoperative 48 hours in the observation group were lower than those in the control group,and the differences were statistically significant(all P＜0.05).No statistically significant differences in the complications such as drowsiness,skin itching,hypoxia,or respiratory depression,etc.existed between the two groups,while the difference in the incidence of adverse reactions between the two groups was statistically significant(P＜0.05).Conclusion Hydromorphone and sufentanil PCIA can relieve the pain in scar pregnancy patients after UAE.Hydromorphone is superior to sufentanil in reducing the number of pressing analgesic pump times within postoperative 48 hours,reducing the used dosage of analgesic drugs,and decreasing the incidence of adverse reactions,therefore,hydromorphone PCIA has a certain promotion value.(J Intervent Radiol,2024,33:240-244)

Objective To investigate the clinicopathological factors associated with pathological complete response(pCR)of axillary metastatic lymph nodes in breast cancer patients after neoadjuvant chemotherapy(NAC),and to analyze the postoperative survival.Methods A total of 116 patients with breast cancer with axillary lymph node metastasis were collected from Jiaxing Hospital of TCM,Jiaxing Maternity and Child Health Care Hospital and The First Hospital of Jiaxing.Univariate analysis was used to analyze the relationship between clinicopathological factors and the pCR of axillary lymph node metastasis in breast cancer after NAC.Binary Logistic regression was used to analyze the independent predictors of the pCR of axillary lymph node metastasis in breast cancer after NAC.Kaplan-Meier survival curve was used to analyze the disease-free survival rate and overall survival rate of patients with and non-pCR of axillary metastatic lymph nodes.Results Among 116 patients,52 cases of axillary metastatic lymph nodes achieved pCR after NAC,accounting for 44.83%.Univariate analysis showed that age,vascular invasion,pCR of primary breast tumor,the difference of Ki67 before and after NAC,NAC regimen,and the efficacy of NAC were statistically significant between breast cancer patients with pCR and those non-pCR(P<0.05).Binary Logistic regression analysis showed that age,vascular invasion and pCR of primary breast tumor were independent predictors of pCR of axillary metastatic lymph nodes(P<0.05).The 5-year disease-free survival rate(80.40%vs.54.60%)and overall survival rate(90.4%vs.70.10%)of patients with pCR and non-pCR of axillary metastatic lymph nodes were compared.Conclusion Some breast cancer patients with axillary lymph node metastasis can reach pCR in lymph nodes after NAC.Analyzing the correlation between clinical pathological factors and pCR of axillary metastatic lymph nodes after NAC,it was found that pCR of axillary metastatic lymph nodes after NAC is related to age≤50 years old,no vascular infiltration,and primary breast tumor pCR.At the same time,it was found that patients with axillary metastatic lymph node pCR had a better prognosis than those with non-pCR.

Objective To investigate the clinical features and risk factors of primary biliary cholangitis(PBC)comorbid with metabolic associated fatty liver disease(MAFLD)and the interaction between the two diseases.Methods A total of 187 patients who were diagnosed with PBC,MAFLD,or PBC with MAFLD in The First Affiliated Hospital of Kunming Medical University from January 2019 to December 2022 were enrolled and divided into PBC group with 70 patients,PBC+MAFLD group with 38 patients,and MAFLD group with 79 patients.Related data were collected,including general information,clinical symptoms,serological parameters,transient elastography(FibroScan),and non-invasive fibrosis markers,which were compared between the three groups.A one-way analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between groups,the chi-square test or the Fisher's exact test was used for comparison of categorical data between groups,and the binary Logistic regression analysis was used for multivariate analysis.Results There were significant differences between the three groups in sex,age,height,weight,body mass index(BMI),and history of autoimmune diseases(P<0.05).In the PBC+MAFLD group,female patients accounted for 89.5%,with a mean age of 57.26±12.72 years and a BMI of 23.35±3.70 kg/m2,and in the PBC group,the detection rate of autoimmune diseases was 25.7%(18 patients).There were significant differences between the three groups in the incidence rates of weakness,poor appetite,pruritus,jaundice,varices,ascites,and splenomegaly(all P<0.05).The PBC+MAFLD group had the common symptoms of weakness in 18 patients(47.4%),poor appetite in 15 patients(39.5%),abdominal pain in 14 patients(36.8%),and abdominal distension in 16 patients(42.1%);the MAFLD group had the common symptoms of abdominal pain in 34 patients(43%)and abdominal distension in 32 patients(40.5%);the PBC group had the common symptoms of weakness in 37 patients(52.9%),poor appetite in 25 patients(35.7%),jaundice in 25 patients(35.7%),abdominal pain in 18 patients(25.7%),abdominal distension in 25 patients(35.7%),varices in 19 patients(27.9%),ascites in 23 patients(32.9%),and splenomegaly in 44 patients(62.9%).The PBC+MAFLD group had a controlled attenuation parameter(CAP),which was higher than that of the PBC group,and the PBC group had significantly higher levels of liver stiffness measurement,aspartate aminotransferase-to-platelet ratio index(APRI),and fibrosis-4(FIB-4)than the MAFLD group(all P<0.05).The factors without multicollinearity were included in the regression analysis,and with the PBC group as the reference group,FIB-4(odds ratio[OR]=0.218,95%confidence interval[CI]:0.069-0.633,P<0.05)and history of autoimmune diseases(OR=0.229,95%CI:0.067-0.810,P<0.05)were influencing factors for the onset of PBC with MAFLD;with the MAFLD group as the reference group,ALT(OR=0.157,95%CI:0.025-1.000,P<0.05)and TBil(OR=0.995,95%CI:0.990-0.999,P<0.05)were influencing factors for the onset of PBC with MAFLD.Conclusion PBC with MAFLD lacks specific clinical manifestations,and PBC patients tend to have more severe clinical manifestations and a higher incidence rate of liver function decompensation.PBC comorbid with MAFLD may not aggravate the disease progression of PBC.

Objective:To explore the risk factors for urinary tract infection (UTI) after a spinal cord injury (SCI).Methods:The medical records of 403 SCI patients were analyzed retrospectively. They were divided into UTI group and no-UTI group according to whether they had a UTI at admission. Gender, age, cause of injury, injury level of the spinal cord, voluntary anal contraction, time from injury to admission, American Spinal Injury Association (ASIA) grade, axillary temperature at admission, complications at admission (diabetes, hypertension, fracture of the pelvis, pressure sores or anemia), white blood cell count and urinary bacteria were compared between the two groups. Binary logistic regression was used to highlight the risk factors for a UTI after an SCI.Results:Of the 354 patients included in the final analysis, 62 (17.51%) had a UTI at admission. The regression showed that UTI after an SCI was closely related to an inability to voluntarily contract the anus, anemia, elevated white blood cell count and a high level of bacteria in the urine.Conclusions:Inability to contract the anus, fever, anemia and an elevated white blood cell count are independent indicators of a UTI after an SCI. A temperature ≥37.3°C is a simple indicator of a concentration of bacteria in the urine ≥1266/μL.

Objective To investigate the clinical efficacy of low-dose plasma exchange (PE) combined with artificial liver in the treatment of acute-on-chronic liver failure (ACLF) and its effect on mortality rate after stratification. Methods A total of 272 ACLF patients who were admitted to Department of Infection and Hepatology, The First Affiliated Hospital of Kunming Medical University, from January 2018 to December 2020 were enrolled and divided into low-dose PE+double plasma molecular absorption system (DPMAS)/hemoperfusion (HP) group ( n =190) and medical treatment group( n =82). Laboratory markers were collected before and after treatment, and clinical outcome was compared between the two groups; stratified analysis (early stage, early-middle stage, late stage or types A, B, C) was performed for the two groups according to Diagnostic and treatment guidelines for liver failure (2018 edition), and all patients were followed up to observe general status and death at 12 weeks (short-term) and 48 weeks (long-term) after discharge. The independent samples t -test was used for comparison of normally distributed continuous data between two groups, and the paired samples t -test was used for comparison before and after treatment; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Wilcoxon test was used for comparison before and after treatment; the chi-square test was used for comparison of categorical data between groups. Results Both low-dose PE combined with DPMAS/HP and medical treatment alone could reduce the levels of alanine aminotransferase (ALT), aspartate aminotransferase, total bilirubin (TBil), and blood ammonia and increase the level of albumin (Alb), and both groups had significant changes in these indices after treatment (all P < 0.05). Compared with medical treatment alone, low-dose PE combined with DPMAS/HP better reduced ALT, TBil, and blood ammonia and improved Alb, with significant changes in these indices after treatment (all P < 0.05). Low-dose PE combined with DPMAS/HP could significantly reduce bile acid, international normalized ratio, neutrophil-lymphocyte ratio, and MELD score and increase platelet-to-white blood cell ratio (all P < 0.05), while medical treatment alone could not improve the above indices (all P > 0.05). Compared with medical treatment alone, low-dose PE combined with DPMAS/HP could reduce the short-term mortality rate of ACLF patients, especially the short-term mortality rate of ACLF patients with early-stage, early-middle-stage or type A ACLF, and there were significant differences between the two groups (all P < 0.05). In the low-dose PE+DPMAS/HP group, the patients with early-stage ACLF had significantly lower short- and long-term mortality rates than those with late-stage ACLF, and the patients with type A ACLF had significantly lower short- and long-term mortality rates than those with type C ACLF (all P < 0.05). Conclusion Low-dose PE combined with DPMAS/HP has good clinical efficacy and can effectively reduce the short-term mortality rate of ACLF, especially the short-term mortality rate of patients with early-stage, early-middle-stage, or type A ACLF.

OBJECTIVE：To study the effects of couplet medicine of Rheum p almatum-Salvia miltiorrhiza on the contents of enterogenous urotoxin and intestinal barrier function in chronic renal failure （CRF）model rats. METHODS ：Totally 55 male Wistar rats were randomly divided into sham operation group （10 rats）and modeling group （45 rats）. In sham operation group ，the kidneys were isolated but not removed ；CRF model was reproduced by 5/6 nephrectomy in modeling group. After modeling （excluding 5 dead and non-modeling rats ），modeling rats were divided into model group （water），Niaoduqing granules group （2.5 g/kg），couplet medicine of R. palmatum -S. miltiorrhiza groups（6，3 g/kg，by crude drug ），with 10 rats in each group. Sham operation group and model group were given constant volume of water intragastrically. Administration groups were given relevant medicine intragastrically ，once a day ，for consecutive 12 weeks. After last administration ，the contents of creatinine （Scr）and urea nitrogen（BUN）in serum ，the content of urinary creatinine （Ucr） in urine were determined by automatic biochemical analyzer；creatinine clearance rate （Ccr）was calculated. The contents of enterogenous urotoxin [trimethylamine-N-oxide （TMAO），indoxyl sulfate （IS）and p-cresyl sulphate （PCS）] were determined by UPLC-ESI-MS/MS. Real-time RT-PCR and immunofluorescence assay were used to detect the mRNA and protein expression of Occludin and ZO-1 in the ileum tissue. HE staining and Masson staining were used to observe the pathologi cal changes of renal tissue. The ultrastructural changes of rat colon were observed by transmission electron microscope. RESULTS ：Compared with sham operation group ，serum contents of Scr，BUN，TMAO，PCS and IS were increased significantly in model group （P＜0.01），while urine content of Ucr ，Ccr，mRNA and protein expression of Occludin and ZO- 1 in ileum tissue were decreased significantly （P＜0.01）；renal glomerulosclerosis ， renal tubules dilation and inflammatory invasion and fibrosisin the interstitium were all found ；the intestinal epithelial barrier structure of colon tissue was severely damaged. Compared with model group ，serum contents of Scr ，BUN，TMAO，PCS and IS were decreased significantly in administration groups （P＜0.05 or P＜0.01）；the mRNA and protein expression of Occludin and ZO-1 in the ileum tissue were increased significantly （except for mRNA expression of ZO- 1 in R. palmatum -S. miltiorrhiza low-dose group （P＜0.05 or P＜0.01）；the infiltration of inflammatory cells in renal interstitium ，the degree of fibrosis and the damage of intestinal epithelial barrier structure in colon tissue were reduced. CONCLUSIONS ：Couplet medicine of R. palmatum -S. miltiorrhiza can effectively protect the residual renal function of CRF model rats ，the mechanism of which may be associated with reducing the serum contents of enterogenous urotoxin ，up-regulating mRNA and protein expresssion of Occludin and ZO- 1 in the ileum tissue so as to improve intestinal barrier function.

Esophageal squamous-cell carcinoma (ESCC) is one of the most lethal malignancies in the world and occurs at particularly higher frequency in China. While several genome-wide association studies (GWAS) of germline variants and whole-genome or whole-exome sequencing studies of somatic mutations in ESCC have been published, there is no comprehensive database publically available for this cancer. Here, we developed the Chinese Cancer Genomic Database-Esophageal Squamous Cell Carcinoma (CCGD-ESCC) database, which contains the associations of 69,593 single nucleotide polymorphisms (SNPs) with ESCC risk in 2022 cases and 2039 controls, survival time of 1006 ESCC patients (survival GWAS) and gene expression (expression quantitative trait loci, eQTL) in 94 ESCC patients. Moreover, this database also provides the associations between 8833 somatic mutations and survival time in 675 ESCC patients. Our user-friendly database is a resource useful for biologists and oncologists not only in identifying the associations of genetic variants or somatic mutations with the development and progression of ESCC but also in studying the underlying mechanisms for tumorigenesis of the cancer. CCGD-ESCC is freely accessible at http://db.cbi.pku.edu.cn/ccgd/ESCCdb.

Objective: To investigate and analyze the impact on PLT recovery of recombinant human thrombopoietin (rhTPO) in severe aplastic anemia (SAA) patients with allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: A retrospective analysis of Hematology Division of General Hospital of Jinan Military Command was conducted in the 85 SAA cases who treated with allo-HSCT from January 2010 to March 2017. According to the administration of medicines for platelets, 85 patients were divided into rhTPO group (n=29), rhIL-11 group (n=27) and blank group (n=29), respectively. The median time of PLT ≥20×10⁹/L, PLT ≥50×10⁹/L, and PLT ≥100×10⁹/L, the numbers of megakaryocytes in marrow smear (25±5) days after transplantation and the quantities of platelet transfusion were analyzed retrospectively. The adverse events of rhTPO and rhIL-11 groups were observed. Results: There were no significant differences in the recovery of granulocytes and PLT ≥20×10⁹/L among the three groups (P>0.05). The time of PLT ≥50×10⁹/L in rhTPO group was shorter than that in blank group [16.5 (11-39) d vs 22 (14-66) d, P<0.05], as well as the time of PLT ≥100×10⁹/L [rhTPO: 23 (12-51) d; rhIL-11: 28 (12-80) d; blank group: 35 (18-86) d, P<0.05]. Platelet transfusions were also less in rhTPO group than in rhIL-11 and blank groups [20 (10-30) U, 30 (10-50) U, 35 (10-70) U, P<0.05]. The counts of megakaryocyte in rhTPO group, rhIL-11 group and blank group were 31.5 (0-200), 12 (0-142) and 11(0-187) (P<0.05), respectively. The difference between rhTPO group and rhIL-11 group was statistically significant (P<0.05), but no difference between rhIL-11 group and blank group (P>0.05). Multivariate analysis showed that rhTPO was an independent factor for platelet recovery [HR=4.01 (95%CI 1.81-9.97), P=0.010]. The rhTPO group had no obvious adverse events. Conclusion rhTPO can promote platelet recovery of SAA patients after allo-HSCT, reduce platelet transfusion with safety.
