BACKGROUND: We sought to investigate whether the unique lateral patterns of lymphatic drainage impacted lymphadenectomy (LND), lymph node metastasis (LNM), and long-term survival of patients after curative hemi-hepatectomy for left- versus right-sided intrahepatic cholangiocarcinoma (ICC).METHODS: Data on patients who underwent curative hemi-hepatectomy for left- or right-sided ICC were collected from 15 high-volume centers worldwide, as well as from the Surveillance, Epidemiology, and End Results (SEER) registry. Primary outcomes included overall survival (OS) and disease-free survival (DFS).RESULTS: Among 697 patients identified from the multi-institutional database, patients who underwent hemi-hepatectomy for left-sided ICC (n = 363, 52.1%) were more likely to have an increased number of LND versus patients with right-sided ICC (n = 334, 47.9%) (median, left 5 versus right 3, p = 0.012), although the frequency (left 66.4% versus right 63.8%, p = 0.469) and station (beyond station no. 12, left 25.3% versus right 21.1%, p = 0.293) were similar. Consequently, left-sided ICC was associated with higher incidence of LNM (left 33.3% versus right 25.7%, p = 0.036), whereas the station and number of LNM were not different (both p > 0.1). There was no difference in OS (median, left 34.9 versus right 29.6 months, p = 0.130) or DFS (median, left 14.5 versus right 15.2 months, p = 0.771) among patients who underwent hemi-hepatectomy for left- versus right-sided ICC, which were also verified in the SEER dataset. LNM beyond station no. 12 was associated with even worse long-term survival versus LNM within station no. 12 among patients with either left- or right-sided ICC after curative-intent resection (all p < 0.05).CONCLUSIONS: The unique lateral patterns of lymphatic drainage were closely related to utilization of LND, as well as LNM of left- versus right-sided ICC.

Background. Systemic lupus erythematosus (SLE) is an autoimmune disease with strong heterogeneity, leading to variable clinical symptoms, which makes diagnosis and activity evaluation difficult. Methods. The original dataset of GSE88884 was analyzed to screen differentially expressed genes (DEGs) of SLE and the correlation between DEGs and clinical parameters (SLEDAI, anti-dsDNA, C3, and C4). The result was validated by microarray GSE121239 and SLE patients with RT-qPCR. Next, receiver operator characteristic (ROC) analysis, correlation analysis, and ordinal logistic regression were applied, respectively, to evaluate the capability of diagnosis and prediction of the candidate biomarker. Subsequently, the biological functions of the candidate biomarker were investigated through KEGG and GO enrichment, protein–protein interaction network, and the correlation matrix. Results. A total of 283 DEGs were screened, and seven of them were overlapped with SLE-related genes. DDX60 was identified as the candidate biomarker. Analyses of GSE88884, GSE121239, and SLE patients with RT-qPCR indicated that DDX60 expression level is significantly higher in patients with high disease activity. ROC analysis and the area under the ROC curve ( AUC = 0.8818 ) suggested that DDX60 has good diagnostic performance. DDX60 expression level was positively correlated with SLEDAI scores ( r = 0.24 ). For every 1-unit increase in DDX60 expression value, the odds of a higher stage of activity of SLE disease are multiplied by 1.47. The function of DDX60 mainly focuses on IFN-I-induced antiviral activities, RIG-I signaling, and innate immune. Moreover, DDX60 plays a synergistic role with DDX58, IFIH1, OASL, IFIT1, and other related genes in the SLE pathogenesis. Conclusions. DDX60 is differently expressed in SLE, and it is significantly related to both serological indicators and the disease activity of SLE. We suggested that DDX60 might be a potential biomarker for SLE diagnosis and management.

The benefit of adjuvant therapy (AT) after curative resection of distal cholangiocarcinoma (DCC) remains unclear. The objective of the current study was to investigate the impact of AT on long-term survival of patients who underwent curative-intent resection for DCC.Patients who underwent curative-intent resection for DCC between 2000 and 2020 were identified from a multi-institutional database. The primary outcomes included overall (OS) and recurrence-free survival (RFS).Among 245 patients, 150 (61.2%) patients received AT (chemotherapy alone: n = 43; chemo- and radiotherapy: n = 107) after surgical resection, whereas 95 (38.8%) patients underwent surgery only. Patients who received AT were younger, and more likely to have an advanced tumor with the presence of perineural invasion (PNI), lymph node metastasis (LNM), lymph-vascular invasion, and higher T categories (all p 0.05). Overall, there was no difference in OS (median, surgery + AT 25.5 vs. surgery alone 24.5 months, p = 0.27) or RFS (median, surgery + AT 15.8 vs. surgery alone 18.9 months, p = 0.24) among patients who did versus did not receive AT. In contrast, AT was associated with improved long-term survival among patients with PNI (median OS, surgery + AT 25.9 vs. surgery alone 17.8 months, p = 0.03; median RFS, surgery + AT 15.9 vs. surgery alone 11.9 months, p = 0.04) and LNM (median, surgery + AT 20.0 vs. surgery alone 17.8 months, p = 0.03), but not among patients with no PNI or LNM (all p 0.1).AT was commonly utilized among patients with DCC. Patients with more advanced disease, including the presence of PNI or LNM, benefited the most from AT with improved long-term outcomes among this subset of patients.

To define surgical outcomes of patients with high-grade gastro-entero-pancreatic neuroendocrine neoplasm grade G3 (GEP-NEN G3).Patients who underwent surgical resection between 2000 and 2016 were identified. The overall survival (OS) and recurrence-free survival (RFS) of patients with gastro-entero-pancreatic neuroendocrine tumors grade G3 (GEP-NET G3) versus neuroendocrine carcinoma (NEC) were evaluated.Fifty-one out of 2182 (2.3%) patients who underwent surgical resection were diagnosed as GEP-NEN G3. The pancreas was the most common primary site (n = 3772.5%). A majority of patients had lymph node metastasis (n = 3262.7%); one in three (n = 1631.4%) had distant metastasis. The median OS and RFS of the entire cohort were 56.4 and 34.5 months, respectively. Perineural invasion was a strong prognostic factor associate with OS after surgical resection. Patients with NEC had a worse survival outcome versus patients with NET G3 (median OS: 33.1 months vs. not attained, p = 0.088). In contrast, among patients who underwent curative-intent resection, patients with NEC had comparable RFS versus patients with NET G3 (median RFS: 35.6 vs. 33.9 months, p = 0.774).Surgical resection provided acceptable short- and long-outcomes for well-selected patients with resectable GEP-NEN G3. NEC was associated with a worse OS versus NET G3.

Simple ileocecectomy and right hemicolectomy are two potential operative approaches to treat patients with neuroendocrine neoplasm in the terminal ileum and/or cecum (IC-NENs). We sought to define the long-term outcome of patients undergoing ileocecectomy versus right hemicolectomy for IC-NENs, as well as characterize number of nodes evaluated and lymph node metastasis (LNM) associated with each procedure.Patients who underwent curative-intent resections for IC-NENs between 2000 and 2016 were identified from a multi-institutional database. The clinicopathologic characteristics, surgical procedures, and the overall (OS) and recurrence-free survival (RFS) were compared among patients who underwent formal right hemicolectomy versus ileocecectomy only.Among 127 patients with IC-NENs, median size of the largest tumor size was 2.0 (IQR 1.2-2.9) cm; 35 (27.6%) patients had multiple lesions. At the time of surgery, 93 (73.2%) patients underwent a right hemicolectomy, whereas 34 (26.8%) had ileocecectomy only. Every patient had a lymph node dissection (LND) with a median number of 16 (IQR 12-22) nodes evaluated. A majority (n = 110, 86.6%) of patients had LNM with a median number of 3 (IQR 2-5) LNM. Patients who underwent hemicolectomy had more lymph nodes evaluated versus patients who had an ileocecectomy only (median, 18 vs. 14, p = 0.004). Patients who underwent formal right hemicolectomy versus ileocecectomy had a similar OS (median OS, 101.9 vs. 144.5 months, p = 0.44) and RFS (median RFS, 70.3 vs. not attained, p = 0.80), respectively.Ileocecectomy had similar long-term outcomes versus right hemicolectomy in treatment of IC-NENs despite a difference in the lymph node harvest.

To characterize the prognostic implication of jaundice and preoperative biliary drainage on postoperative outcomes among patients with gallbladder cancer (GBC) undergoing surgical resection.Patients who underwent surgical resection of GBC identified from a multicenter database between January 2000 and December 2019 were retrospectively analyzed. Data on clinical and pathological details, as well as short- and long-term overall survival (OS), were obtained and compared among patients with and without preoperative jaundice and biliary drainage.Among 449 patients with GBC, median and 1-, 3-, and 5-year OS were 17.4 months, 63.7%, 28.4%, and 22.1%, respectively. Patients who presented with preoperative jaundice (n = 100, 22.3%) were more likely to have advanced disease, a lower incidence of R0 resection (29.0% vs. 69.1%, p 0.001), as well as a higher incidence of postoperative liver failure (4% vs. 0, p = 0.002), and worse long-term survival versus patients without jaundice (median OS, 10.4 vs. 27.1 months, p 0.001). Preoperative biliary drainage was performed for the majority of jaundiced patients (77.0%) and was associated with decreased risk of postoperative liver failure (1.3% vs. 13.0%, p = 0.041); preoperative biliary drainage failed to improve long-term survival (median OS, 10.2 months vs. 12.0 months, p = 0.679). On multivariable analysis, R0 resection (17.5 vs. 7.6 months, p 0.001) and adjuvant therapy (15.6 vs. 6.6 months, p = 0.027) were associated with improved long-term survival among jaundiced patients.While preoperative biliary drainage of jaundiced GBC patients decreased the risk of postoperative liver failure, it did not impact long-term outcomes. Rather, preoperative jaundice was associated with a lower chance at R0 resection and worse long-term survival.

BACKGROUNDThe removal of bilirubin from serum is the primary method for treating hyperbilirubinemia. However, currently used treatment methods have several limitations. This study was designed to introduce a novel method to remove bilirubin from the blood of jaundiced rats.METHODSThis novel therapy involved cross-circulation of blood between a rat liver preserved in vitro and a rat with hyperbilirubinemia. All model animals were randomly divided into two groups based on whether they received the novel therapy. Serum samples were collected at different time points. The levels of serum transaminase and bilirubin were detected and compared between different groups. Long-term survival was compared by Kaplan-Meier analysis between different groups.RESULTSAcross different hyperbilirubinemia models, serum total bilirubin level was significantly improved (24.8 ± 1.2 vs. 17.4 ± 1.2 µmol/L, P P>0.05; ALT: 5051 ± 722 vs. 5488 ± 707 U/L, PP CONCLUSIONThis novel method could safely and effectively help eliminate bilirubin from the blood of jaundiced rats.

Background: Kashin-Beck disease (KBD) can seriously affect labor capacity. In recent years, KBD is mainly a disease of poor farming families, which are primarily distributed in China. The purpose of this study was to assess the effectiveness of control strategies implemented in China, and provide the basis for formulating relevant strategies to eliminate KBD in the future. Method: This study collected demographic information of adult KBD cases by census.Result: KBD is particularly serious in the Tibetan region with a high prevalence and a high proportion of young patients. Most patients were ethnically Han and Tibetan, farmers and herdsmen. Low-income patients showed higher disability rates, long-term medication ratios and operative intention than higher-income patients. Conclusion: The age composition of KBD patients demonstrates that comprehensive prevention and treatment measures implemented in China since the 1990s have achieved remarkable results. The treatment of adult KBD patients, especially those with a lower income, is currently an important part of the effort to eliminate KBD.

Second-trimester induced labor in pregnant women was often more likely to suffer from psychological and physiological double pain. However, the analgesic management received less attention, and the optimal analgesic mode for second-trimester induced labor had not been determined. Our objective was to evaluate the feasible of epidural analgesia (EA) in second-trimester induced labor.From January 2020 to December 2021, Primipara who planned to undergo second-trimester induced labor in the First Affiliated Hospital of Yangtze University were collected. The method of labor induction was oral mifepristone + amniotic cavity injection of Ethacridine Lactate. Based on whether or not patients received epidural analgesia, which were divided into EA group (30 cases) and non-EA (NEA) group (30 cases). The primary outcome were visual analog scale (VAS) score of pain and result of follow-up, the secondary outcomes included relative clinical parameter and labor duration.Vaginal induction of labor was successful in both groups. There was no statistically significant difference in VAS of pain between the two groups before analgesia (P .05), but the VAS of pain in the EA group was significantly lower than the NEA group (P .05) after analgesia or at delivery. The following outcomes showed no statistical difference between two groups: labor duration, postpartum hemorrhage, hemorrhage ≥ 500 mL, intrapartum injury, second days hemoglobin, C-reactive protein, antibiotic therapy days, hospitalizations days, and placenta residue (P .05). The median hospitalization costs of EA group was 4697.5 yuan, and NEA group was 3673 yuan, the difference was statistically significant (P .001). No adverse events related to EA occurred during hospitalization, only 3 patients showed mild lumbago and back pain after follow-up to three months postpartum, which was significantly relieved after proper rest.EA can significantly reduce the pain of parturients, which may be effective and safe in the second-trimester induced labor.
