RESUMO

Background: Recent studies have demonstrated that activated microglia were involved in the pathogenesis of central sensitization characterized by cutaneous allodynia in migraine. Activation of microglia is accompanied by increased expression of its receptors and release of inflammatory mediators. Acupuncture and its developed electroacupuncture (EA) have been recommended as an alternative therapy for migraine and are widely used for relieving migraine-associated pain. However, it remains rare studies that show whether EA exerts anti-migraine effects via inhibiting microglial activation related to a release of microglial receptors and the inflammatory pathway. Therefore, this study aimed to investigate EA' ability to ameliorate central sensitization via modulation of microglial activation, microglial receptor, and inflammatory response using a rat model of migraine induced by repeated epidural chemical stimulation. Methods: In the present study, a rat model of migraine was established by epidural repeated inflammatory soup (IS) stimulation and treated with EA at Fengchi (GB20) and Yanglingquan (GB34) and acupuncture at sham-acupoints. Pain hypersensitivity was further determined by measuring the mechanical withdrawal threshold using the von-Frey filament. The changes in c-Fos and ionized calcium binding adaptor molecule 1 (Ibal-1) labeled microglia in the trigeminal nucleus caudalis (TNC) were examined by immunflurescence to assess the central sensitization and whether accompanied with microglia activation. In addition, the expression of Ibal-1, microglial purinoceptor P2X4, and its associated inflammatory signaling pathway mediators, including interleukin (IL)-1ß, NOD-like receptor protein 3 (NLRP3), and Caspase-1 in the TNC were investigated by western blot and real-time polymerase chain reaction analysis. Results: Allodynia increased of c-Fos, and activated microglia were observed after repeated IS stimulation. EA alleviated the decrease in mechanical withdrawal thresholds, reduced the activation of c-Fos and microglia labeled with Ibal-1, downregulated the level of microglial purinoceptor P2X4, and limited the inflammatory response (NLRP3/Caspase-1/IL-1ß signaling pathway) in the TNC of migraine rat model. Conclusions: Our results indicate that the anti-hyperalgesia effects of EA ameliorate central sensitization in IS-induced migraine by regulating microglial activation related to P2X4R and NLRP3/IL-1ß inflammatory pathway.

RESUMO

BACKGROUND: For patients with rectal cancer, the utilization of temporary ileostomy (TI) has proven effective in minimizing the occurrence of severe complications post-surgery, such as anastomotic leaks; however, some patients are unable to reverse in time or even develop a permanent stoma (PS). We aimed to determine the preoperative predictors associated with TS failure and develop and validate appropriate predictive models to improve patients' quality of life. METHODS: This research included 403 patients with rectal cancer who underwent temporary ileostomies between January 2017 and December 2021. All patients were randomly divided into either the developmental (70%) or validation (30%) group. The independent risk factors for PS were determined using univariate and multivariate logistic regression analyses. Subsequently, a nomogram was constructed, and the prediction probability was estimated by calculating the area under the curve (AUC) using receiver operating characteristic (ROC) analysis. A calibration plot was used to evaluate the nomogram calibration. RESULTS: Of the 403 enrolled patients, 282 were randomized into the developmental group, 121 into the validation group, and 58 (14.39%) had a PS. The development group consisted of 282 patients, of whom 39 (13.81%) had a PS. The validation group consisted of 121 patients, of whom, 19 (15.70%) had a PS; 37 related factors were analyzed in the study. Multivariate logistic regression analysis demonstrated significant associations between the occurrence of PS and various factors in this patient cohort, including tumor location (OR = 6.631, P = 0.005), tumor markers (OR = 2.309, P = 0.035), American Society of Anesthesiologists (ASA) score (OR = 4.784, P = 0.004), T4 stage (OR = 2.880, P = 0.036), lymph node metastasis (OR = 4.566, P = 0.001), and distant metastasis (OR = 4.478, P = 0.036). Furthermore, a preoperative nomogram was constructed based on these data and subsequently validated in an independent validation group. CONCLUSION: We identified six independent preoperative risk factors associated with PS following rectal cancer resection and developed a validated nomogram with an area under the ROC curve of 0.7758, which can assist surgeons in formulating better surgical options, such as colostomy, for patients at high risk of PS.

RESUMO

BACKGROUND: Temporary ileostomy (TI) has proven effective in reducing the severity of anastomotic leakage after rectal cancer surgery; however, some ileostomies fail to reverse over time, leading to conversion into a permanent stoma (PS). In this study, we aimed to investigate the preoperative risk factors and cumulative incidence of TI non-closure after sphincter-preserving surgery for rectal cancer. MATERIALS AND METHODS: We conducted a meta-analysis after searching the Embase, Web of Science, PubMed, and MEDLINE databases from their inception until November 2023. We collected all published studies on the risk factors related to TI non-closure after sphincter-preserving surgery for rectal cancer. RESULTS: A total of 1610 studies were retrieved, and 13 studies were included for meta-analysis, comprising 3026 patients. The results of the meta-analysis showed that the identified risk factors included older age (p = 0.03), especially > 65 years of age (p = 0.03), male sex (p = 0.009), American Society of Anesthesiologists score ≥ 3 (p = 0.004), comorbidity (p = 0.001), and distant metastasis (p < 0.001). Body mass index, preoperative hemoglobin, preoperative albumin, preoperative carcinoma embryonic antigen, tumor location, neoadjuvant chemoradiotherapy, smoking, history of abdominal surgery, and open surgery did not significantly change the risk of TI non-closure. CONCLUSION: We identified five preoperative risk factors for TI non-closure after sphincter-preserving surgery for rectal cancer. This information enables surgeons to identify high-risk groups before surgery, inform patients about the possibility of PS in advance, and consider performing protective colostomy or Hartmann surgery.

RESUMO

BACKGROUND: In some earlier studies, self-pulling and later transection (SPLT) esophagojejunostomy (E-J) was incorporated into total laparoscopic total gastrectomy (TLTG) procedures. Its effectiveness and safety, however, remain unknown. This study compared (SPLT)-E-J in TLTG with conventional E-J in laparoscopic-assisted total gastrectomy (LATG) in order to assess the short-term safety and efficacy of (SPLT)-E-J in TLTG. METHODS: This research analyzed patients with gastric cancer who received SPLT-TLTG or LATG between January 2019 and December 2021 in the First Affiliated Hospital of Chongqing Medical University. Baseline data and postoperative short-term surgical outcomes were obtained retrospectively and compared between the two groups. RESULTS: A total of 83 patients who underwent SPLT-TLTG (n = 40, 48.2%) or LATG (n = 43, 51.8%) were included in this study. There were no differences between the two groups in terms of patient demographics or tumor characteristics. No statistically significant differences were observed between the two groups in terms of operation time, intraoperative blood loss, harvested lymph nodes, postoperative complications, postoperative decrease in hemoglobin and albumin levels, or postoperative hospital stay. Five and seven patients experienced short-term postoperative complications in the SPLT-TLTG and LATG groups, respectively. CONCLUSIONS: SPLT-TLTG is a dependable and safe surgical method for the treatment of gastric cancer. Its short-term outcomes were similar to those of conventional E-J in LATG and had advantages regarding surgical incision and simplification of reconstruction.

RESUMO

PURPOSE: The purpose of this case report is to present a very atypical case of cervical intervertebral disc calcification (IDC) with extreme lateral herniated calcification in a child. This is the first ever reported case in which T2-weighted signal intensity of the involved disc was restored to normal after a 2-year follow-up. METHODS: A 10-year-old girl presented with neck pain and right upper limb numbness for 2 months. The initial computed tomography (CT) images on admission showed calcified nucleus pulposus with extreme lateral herniated calcification at the C6-C7 level. Meanwhile, T2-weighted magnetic resonance imaging (MRI) revealed decreased signal intensity of the involved disc. The patient was treated conservatively with nonsteroidal anti-inflammatory drugs and jaw-occipital belt traction for 2 weeks. The cervical CT and MRI scans were repeated at 2-year follow-up. RESULTS: Her clinical symptoms were completely resolved after 2 weeks. At 2-year follow-up, CT and MRI images demonstrated that calcification was completely absorbed and T2-weighted signal intensity of the C6-C7 disc was restored back to normal. CONCLUSION: Cervical IDC combined with extreme lateral herniated calcification is extremely rare in children. The recovery of signal intensity of intervertebral disc on MRI may provide further support to the feasibility of conservative treatment of IDC.

RESUMO

OBJECTIVE: To investigate the effect of electroacupunctrue on ERp57 in non-alcoholic fatty liver disease (NAFLD) rats, and study the therapeutic mechanism of electroacupunctrue in patients with NAFLD. METHODS: Sixty male SD rats were randomly divided into common diet group (n = 15) and high-fat diet group (n = 45). 5 weeks later, two rats from the two groups were executed and confirmed that the model was successful. Then 10 rats in common diet group were chosen as control group (Control), and 40 rats in high-fat diet group were randomly chosen and divided into diet group 1 (D1), diet group 2 (D2), electroacupuncture group 1 (EA) and electroacupuncture group 2 (EA2) (n = 10 each). D1 and EA1 were fed by high fat diet; D2 and EA2 were fed with common diet. In EA1 and EA2, filiform needle acupuncture was applied to ST36, SP6 and Liv3 and electroacupunctrue was applied to one-side of ST36, SP6 for 20 min once daily for 4 weeks. The rats in each group were weighed per-week. After the treatment the changes of blood lipid and liver functions of these rats were observed. ERp57 gene expression and protein expression were detected by RT-PCR and Western blot, and expression of ERp57 downstream SREBP-1c was detected. RESULTS: The body mass of D1 increased slowly and were lower than D2 and EA1 (P < 0.05); the body weights of EA2 increased rapidly and were higher than EA1 (P < 0.05), but without significant difference with D2 (P > 0.05). The contents of blood lipid, liver functions and the expression of ERp57 and SREBP-1c were significantly higher than those in Control, D2 and EA1 (P < 0.05). While compared to D2 and EA1 respectively, the index mentioned above in EA2 decreased more significantly (P < 0.05). CONCLUSION: Electroacupunctrue can decrease expression of ERp57 to improve endoplasmic reticulum stress (ERS) of rats with NAFLD and then decrease expression of SREBP-1c to regulate rat lipid, which could be one of mechanism to cure NAFLD.

RESUMO

OBJECTIVE: To observe the effect and mechanism of electroacupuncture (EA) on non-canonical pathway of hepatocellular pyroptosis in nonalcoholic fatty liver disease (NAFLD). METHODS: Sixty male SD rats were randomly divided into a normal diet group (n=15) and a high fat modeling group (n=45). The rats in the high fat modeling group were fed with customized high fat diet for 8 weeks to establish NAFLD model. Thirty successfully modeled rats were selected and randomly divided into a model group (n=10), an EA group (n=10) and a non-acupoint with shallow needling group (n=10), and 10 rats were randomly selected from the normal diet group as the control group additionally. In the EA group, EA was applied at bilateral "Fenglong" (ST 40) and "Ganshu" (BL 18), with disperse-dense wave, in frequency of 4 Hz/20 Hz and in intensity of 3 mA. In the non-acupoint with shallow needling group, shallow needling was delivered at points 5 mm from bilateral "Fenglong" (ST 40) and "Ganshu" (BL 18), the EA stimulation parameters were same as the EA group. The intervention was given once a day, 20 min a time, 5 days a week for 4 weeks in the two groups. After intervention, the liver morphology was observed by oil red "O" staining, the serum levels of lipopolysaccharide (LPS), interleukin (IL)-1ß, IL-18 and tumor necrosis factor-α (TNF-α) were detected by ELISA, the protein expression of gasdermin D (GSDMD), GSDMD-N, cysteine aspartic acid specific protease-11 (Caspase-11), IL-1ß, IL-18 and TNF-α in liver tissue were detected by Western blot, the mRNA expression of GSDMD, Caspase-11, IL-1ß, IL-18 and TNF-α in liver tissue was detected by real-time PCR in rats of each group. RESULTS: In the model group, vacuoles in different size were found in the hepatocellular cytoplasm, and the fat droplets were in schistose accumulation. Compared with the model group, the hepatocellular fat droplets and the degree of hepatic steatosis were reduced in the EA group and the non-acupoint with shallow needling group. Compared with the control group, the serum levels of LPS, IL-1ß, IL-18 and TNF-α were increased (P<0.01), the protein and mRNA expression of GSDMD, Caspase-11, IL-1ß, IL-18, TNF-α as well as the protein expression of GSDMD-N in the liver tissue were increased (P<0.01) in the model group. Compared with the model group, the serum levels of LPS, IL-1ß, IL-18 and TNF-α were decreased (P<0.01), the protein and mRNA expression of GSDMD, IL-1ß, IL-18 and TNF-α in the liver tissue were decreased (P<0.01), the protein expression of GSDMD-N and the mRNA expression of Caspase-11 in the liver tissue were decreased (P<0.01) in the EA group and the non-acupoint with shallow needling group. Compared with the model group, the protein expression of Caspase-11 in the liver tissue was decreased (P<0.01) in the EA group. Compared with the non-acupoint with shallow needling group, the serum levels of LPS, IL-1ß, IL-18 and TNF-α were decreased (P<0.01), the protein and mRNA expression of GSDMD, Caspase-11, IL-1ß and IL-18 in the liver tissue were decreased (P<0.01), the protein expression of GSDMD-N and the mRNA expression of TNF-α in the liver tissue were decreased (P<0.01) in the EA group. CONCLUSION: EA can inhibit hepatocellular pyroptosis in NAFLD rats, and its mechanism may be related to reducing the serum level of LPS, and down-regulating the expression of the non-canonical pathway related factors i.e. GSDMD, GSDMD-N, Caspase-11, IL-1ß, IL-18 and TNF-α.

RESUMO

BACKGROUND: The muscle cells myocytes are differentiated for the purpose of contraction function, which plays a major role in body metabolism and energy haemostasis, through different metabolic pathways, such as glucose and protein metabolic pathways. Alanine aminotransferase (ALT) plays a crucial role by reversibly catalysing transamination between alanine and a-ketoglutarate to form pyruvate and glutamate and by mediating the conversion of these four major intermediate metabolites. ALT plays important roles for energy homeostasis during fasting and prolonged exercise anaerobically, when muscle protein must first be broken down into its constituent amino acids. METHODS: Mouse skeletal myoblast cell line C2C12 was cultured in Dulbecco's modified eagle medium (DMEM) growth medium, supplied with 2% horse serum supplemented with 1 uM insulin, 2 mM glutamine and penicillin and streptomycin antibiotics for seven days. The differentiation medium is refreshed every 24 hours. Then, C2C12 cells were treated with insulin and dexamethasone to examine their effects on myocytes' ALT activity. RESULTS: In our study, we found an impact on ALT activity under different influences, including C2C12 differentiation, dexamethasone and insulin treatments, which shed light on the dynamic interplay between ALT activity, alanine metabolism, and cellular states, like differentiation and stress responses. CONCLUSION: The study provides valuable insights into the dynamic regulation of ALT activity and alanine metabolism in C2C12 cells across differentiation and drug treatments. Further research is encouraged to explore the underlying mechanisms and their implications for muscle function, differentiation and potential therapeutic interventions in metabolic disorders.

RESUMO

Pseudostellaria heterophylla (or Taizishen in Chinese), a medicinal, edible, and ornamental Chinese herb, is seriously affected by leaf spot disease (LSD). Oligochitosan is a natural agricultural antibiotic that is produced via the degradation of chitosan, which is deacetylated from chitin; pyraclostrobin is a broad-spectrum and efficient strobilurin fungicide. In this work, the ability of pyraclostrobin, oligochitosan, and their formula to manage P. heterophylla leaf spot disease and their role in its resistance, leaf photosynthesis, agronomic plant traits, root growth, and root quality were studied. The results show that the joint application of oligochitosan and low-dosage pyraclostrobin could control LSD more efficiently, with control effects of 85.75-87.49% compared to high-dosage pyraclostrobin or oligochitosan alone. Concurrently, the application of this formula could more effectively improve the resistance, leaf photosynthesis, agronomic plant traits, root yield, and medicinal quality of P. heterophylla, as well as reduce the application of pyraclostrobin. This finding suggests that 30% pyraclostrobin suspension concentrate (SC) 1500-time + 5% oligosaccharin aqueous solutions (AS) 500-time diluent can be recommended for use as a feasible formula to manage LSD and reduce the application of chemical pesticides.

RESUMO

Radical resection of rectal cancer is a safe and effective treatment, but there remain several complications related to anastomosis. We aimed to assess the risk factors and incidence of rectal anastomotic stenosis (AS) after rectal cancer resection. We conducted a systematic review and meta-analysis after searching PubMed, Embase, Web of Science, and Medline databases from inception until May 2023. Data are reported as the combined odds ratio (OR) for categorical variables and the weighted mean difference (WMD) for continuous variables. Six hundred and fifty-nine studies were retrieved, nine (3031 patients) of which were included in the meta-analysis. Young age (WMD = -3.09, P = 0.0002), male sex (OR = 1.53, P = 0.0002), smoking (OR = 1.54, P = 0.009), radiotherapy (OR = 2.34, P = 0.0002), protective stoma (OR = 2.88, P = 0.007), intersphincteric resection surgery (OR = 6.28, P = 0.05), anastomotic fistula (OR = 3.72, P = 0.003), and anastomotic distance (WMD = -3.11, P = 0.0006) were identified as factors that increased the risk of AS, while staple (OR = 0.39, P < 0.001) was a protective factor. The incidence of AS after rectal cancer resection was approximately 17% (95% CI: 13%-21%). We identified eight risk factors and one protective factor associated with AS after rectal cancer resection. These factors may be combined in future studies to develop a more comprehensive and accurate prediction model related to AS after rectal cancer resection.

RESUMO

PURPOSE: Currently, there is no consensus regarding whether super-elderly (aged > 80 years) patients are suitable candidates for laparoscopic surgery. This study aimed to analyse the short-term outcomes and oncological prognosis of laparoscopic gastrectomy in super-elderly patients with gastric cancer (GC). METHODS: Following PRISMA and AMSTAR-2 guidelines, we searched the Web of Science, Embase, Cochrane Library, and Pubmed databases from inception until May 2024 and performed a meta-analysis. All published studies exploring the surgical outcomes and oncological prognosis of laparoscopic versus open gastrectomy in super-elderly patients with GC were reviewed. Statistical analyses were performed using RevMan 5.3. RESULTS: A total of 1,085 studies were retrieved, eight of which were included in the meta-analysis, comprising 807 patients > 80 years of age with GC. The meta-analysis showed that compared with open gastrectomy, patients with GC > 80 years old who underwent laparoscopic gastrectomy had a longer operative time (weighted mean difference [WMD] = 30.48, p < 0.001), less intraoperative blood loss (WMD = -166.96, P < 0.001), shorter postoperative exhaust time (WMD =-0.83, p < 0.001), shorter length of stay (WMD = -0.78, p < 0.001), fewer overall complications (Odds ratio [OR] = 0.54, p = 0.003), higher 5-year overall survival rate (OR = 1.66, p = 0.03) and disease-specific survival rate (OR = 3.23, p < 0.001). Furthermore, laparoscopic gastrectomy did not significantly affect the number of lymph node dissections, the rate of D2 radical gastrectomy, major postoperative complications, or postoperative pneumonia. CONCLUSIONS: Compared to open gastrectomy, patients with GC aged > 80 years who underwent laparoscopic gastrectomy may have better short-term outcomes. Age should not be a contraindication for minimally invasive surgery.

RESUMO

Introduction: The ligamentum teres hepatis may block the field of vision during totally laparoscopic gastrectomy (TLG), especially in patients with obesity. Aim: We used electrocautery to increase the visual field of TLG by shrinking the ligamentum teres hepatis. This procedure is termed electro-vaporization of the ligamentum teres hepatis (EVLTH). Methods: Patients with body mass index (BMI) ≥24 who underwent total laparoscopic distal gastrectomy (TLDG) or total laparoscopic total gastrectomy (TLTG) between January 2020 and December 2023 were retrospectively enrolled. According to the scope of gastrectomy and whether the patients underwent EVLTH, the patients were divided into the TLDG-EVLTH, TLDG-NEVLTH, TLTG-EVLTH, and TLTG-NEVLTH groups. The clinical characteristics, surgical outcomes, and pathological features were compared between the TLDG-EVLTH and TLDG-NEVLTH groups and the TLTG-EVLTH and TLTG-NEVLTH groups. Results: This study included 65 patients who underwent TLDG (EVLTH: NEVLTH = 29:36) and 32 patients who underwent TLTG (EVLTH:NEVLTH = 15:17). There were no significant differences in clinical characteristics, surgical outcomes, and pathological features between the TLDG-EVLTH and TLDG-NEVLTH groups. However, the operation time in the TLTG-EVLTH group was significantly shorter than that in the TLTG-NEVLTH group, and the difference was statistically significant, although differences in other data were not statistically significant. Conclusions: EVLTH is a simple and safe procedure that reduces the operation time of TLTG in patients who are overweight and enhances the field of vision of TLG.

RESUMO

OBJECTIVES: To analyze the effects of electroacupuncture (EA) at "Fenglong" (ST40) and "Zusanli" (ST36) of different intensities and durations on rats with non-alcoholic fatty liver disease (NAFLD) based on the protein kinase R-like endoplasmic reticulum kinase (PERK)-activating transcription factor 4 (ATF4)-C/EBP homologous protein (CHOP) signaling pathway, so as to explore its mechanism underlying improvement of NAFLD. METHODS: SD rats were randomly divided into normal diet group, high-fat model group, sham EA group, strong stimulation EA (SEA) group, and weak stimulation EA (WEA) group, with 15 rats in each group. Each group was further divided into 2, 3, and 4-week subgroups. NAFLD rat model was established by feeding a high-fat diet. After successful modeling, rats in the SEA and WEA groups received EA at bilateral ST40 and ST36 with dense and sparse waves (4 Hz/20 Hz) at current intensities of 4 mA (SEA group) and 2 mA (WEA group), lasting for 20 minutes, once a day, 5 days a week with 2 days of rest. The sham EA group only had the EA apparatus connected without electricity. Different duration subgroups were intervened for 2, 3, and 4 weeks. After the intervention, the contents of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in rats were detected by an automatic biochemical analyzer;liver morphological changes were observed by Oil Red O staining;real-time fluorescence quantitative PCR and Western blot were used to detect the expression of PERK, ATF4, and CHOP mRNAs and proteins in the rat liver tissue. RESULTS: In the high-fat model group, there was a significant accumulation of red lipid droplets in the liver cells, which was reduced significantly in the SEA group at the 4th week. Compared with the normal diet group with the same treatment duration, the contents of serum ALT, AST, and the expression of PERK, ATF4, and CHOP mRNAs and proteins in the liver tissue were elevated (P<0.01) in the high-fat model group . Compared with the high-fat model group with the same treatment duration, the contents of serum ALT, AST, and the expression of PERK, ATF4, CHOP mRNAs and proteins in the liver tissue were decreased (P<0.01, P<0.05) in the SEA and WEA groups. Compared with the sham EA group with the same treatment duration, the contents of serum ALT, AST, and the expression of PERK, ATF4, and CHOP mRNAs were decreased (P<0.01, P<0.05) in the SEA and WEA groups, the expression of PERK, ATF4, and CHOP proteins in the liver tissue was decreased (P<0.01) in the SEA group at the 2nd, 3rd, and 4th week, the expression of PERK and CHOP proteins at the 2nd, 3rd, 4th week and ATF4 protein at 2nd week in the liver tissue were decreased (P<0.01, P<0.05) in the WEA group. Compared with the SEA group with the same treatment duration, the contents of serum ALT, AST, and the expression of PERK, ATF4, and CHOP mRNAs and proteins in the liver tissue were elevated (P<0.05, P<0.01) in the WEA group. Compared with the 2-week time point within the groups, the contents of serum ALT, AST, and the expression of PERK, ATF4, and CHOP mRNAs and PERK proteins in the liver tissue were decreased (P<0.01, P<0.05) in the SEA and WEA groups at 3rd and 4th week, the expression of ATF4 proteins in the liver tissue was decreased (P<0.01) in the SEA group at 3rd and 4th week, and the expression of CHOP proteins in the liver tissue was decreased (P<0.01) in the SEA group at 4th week and in the WEA group at 3rd and 4th week. Compared with the 3-week time point within the groups, the contents of serum ALT, AST, and the expression of PERK, ATF4, and CHOP mRNAs were significantly decreased (P<0.05, P<0.01) in the SEA and WEA groups at 4th week, the expression of PERK and CHOP proteins in the liver tissue was decreased (P<0.01) in the SEA and WEA groups at 4th week, and the expression of ATF4 protein in the liver tissue was decreased (P<0.05) in the SEA group at 4th week. CONCLUSIONS: EA at ST40 and ST36 can significantly improve liver function in NAFLD rats, and its mechanism of action may involve inhibiting PERK expression thereby targeting the downstream ATF4/CHOP signaling pathway to suppress endoplasmic reticulum stress, exerting a liver protective effect;the optimal effect was observed with EA intensity of 4 mA for 4 weeks.

RESUMO

BACKGROUND: Due to the prolonged life expectancy and increased risk of colorectal cancer (CRC) among patients with human immunodeficiency virus (HIV) infection, the prognosis and pathological features of CRC in HIV-positive patients require examination. AIM: To compare the differences in oncological features, surgical safety, and prognosis between patients with and without HIV infection who have CRC at the same tumor stage and site. METHODS: In this retrospective study, we collected data from HIV-positive and -negative patients who underwent radical resection for CRC. Using random stratified sampling, 24 HIV-positive and 363 HIV-negative patients with colorectal adenocarcinoma after radical resection were selected. Using propensity score matching, we selected 72 patients, matched 1:2 (HIV-positive:negative = 24:48). Differences in basic characteristics, HIV acquisition, perioperative serological indicators, surgical safety, oncological features, and long-term prognosis were compared between the two groups. RESULTS: Fewer patients with HIV infection underwent chemotherapy compared to patients without. HIV-positive patients had fewer preoperative and postoperative leukocytes, fewer preoperative lymphocytes, lower carcinoembryonic antigen levels, more intraoperative blood loss, more metastatic lymph nodes, higher node stage, higher tumor node metastasis stage, shorter overall survival, and shorter progression-free survival compared to patients who were HIV-negative. CONCLUSION: Compared with CRC patients who are HIV-negative, patients with HIV infection have more metastatic lymph nodes and worse long-term survival after surgery. Standard treatment options for HIV-positive patients with CRC should be explored.

RESUMO

Background: Electroacupuncture (EA) is used to treat inflammatory bowel disease (IBD). Nevertheless, the precise mechanisms by which this approach safeguards against obesity-induced intestinal barrier damage has not been fully understood. Objective: This study aimed to assess whether EA could ameliorate intestinal barrier damage that had been reversed in a mouse model of obesity induced by a high-fat diet (HFD) and whether this repair is correlated with ferroptosis and gut microbiota enhancement. Methods: To assess the potential of EA to prevent obesity and restore the intestinal barrier, we divided in C57BL/6J mice into two groups; one was fed with HFD and another one with a normal diet. Samples of stool, blood, fat, and intestinal epithelium were then evaluated, along with body weight. Results: Following EA, we observed a significant reduction in body weight, fat accumulation, and serum triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels; an increase was seen in high-density lipoprotein cholesterol (HDL-C) levels. EA also activated the Nrf2 signaling pathway; upregulated the expression of GPX4, FTH1, and SLC7A11; and downregulated the expression of TFR1. In addition, the administration of EA resulted in a notable modification of the gut microbiota composition, characterized by a decrease in the Firmicutes to Bacteroidetes ratio. Conclusion: EA had beneficial effects on weight loss and showed potential ability to repair the intestinal barrier by activating the Nrf2 signaling pathway, inhibiting intestinal inflammation and ferroptosis, and regulating the intestinal microbiota to treat IBD caused by HFD-induced obesity.

RESUMO

BACKGROUND: Acupuncture combined with nucleos(t)ide analogues (NAs) has shown promise in treating chronic hepatitis B (CHB), though mechanisms remain unclear. This study evaluates the antiviral effects of combining acupuncture with NAs against hepatitis B virus (HBV) and explores underlying mechanisms. METHODS: The HBV-infected mouse model, established using the high-pressure hydrodynamic method, was divided into three groups: normal saline (NS), tenofovir disoproxil fumarate (TF), and electroacupuncture combined with TF (E_T), n = 6. Antiviral effects were assessed by monitoring HBV DNA, HBsAg, and HBeAg levels weekly. Mechanistic insights were gained via transcriptomics, metabolomics, and 16S rDNA sequencing, validated by WB, PCR, and flow cytometry. RESULTS: Serum HBV DNA levels decreased by 1.98 log10 IU/mL in TF and 2.2 log10 IU/mL in E_T groups compared to NS. Serum HBeAg decreased by 10.61 % in TF and 35.75 % in E_T, while HBsAg decreased by 7.38 % and 37.58 %, respectively. Multi-omics indicated E_T modulates the PPAR pathway, upregulates taurine and all-trans-retinoic acid, and increases gut microbiota like Bacteroides and Blautia. E_T also enhanced tight junction proteins (ZO-1, Occludin, Claudin-4), improving intestinal barrier integrity. Mechanistically, E_T inhibited the PGC-1α/PPAR-α/SIRT1 pathway, reducing PGC-1α, PPAR-α, SIRT1, RXRα, and HNF4α, while promoting JAK/STAT signaling via IFN-γ, p-JAK1, p-JAK2, p-STAT1, IRF8, and suppressing SOCS-1. CONCLUSION: E_T more effectively inhibited HBV replication, showing superior antigen inhibition, particularly HBsAg, than TF alone. This may be due to PPAR-JAK/STAT pathway regulation, suggesting E_T as a potential adjuvant therapy for CHB, especially in achieving a functional cure.

RESUMO

Background: Chronic hepatitis B (CHB) remains a global health challenge, necessitating innovative therapeutic strategies. Enhancing the body's immune response against the hepatitis B virus (HBV) emerges as a fundamental strategy for achieving a functional cure. While acupuncture has shown potential in immune modulation, its specific anti-HBV effects are not well understood. This study evaluates the potential of electroacupuncture (EA) in HBV infection and explores its underlying immunological mechanisms using a mouse model. Methods: HBV-infected mice were established using the high-pressure hydrodynamic method and divided into four groups: normal saline (NS), EA, sham EA (SE), and tenofovir disoproxil fumarate (TF), with n = 6 per group. During treatment, blood was collected every Sunday via the orbital sinus to monitor HBV DNA, HBsAg, and HBeAg levels. Transcriptomics and metabolomics analyses were employed to unearth clues regarding EA's anti-HBV mechanism. Validation of these mechanisms included splenic T-cell flow analysis, Western blotting, RT-qPCR, immunofluorescence, and ELISA. Results: Serum HBV DNA levels decreased by 1.10, 0.19, and 1.98 log10 IU/mL in the EA, SE, and TF-treated mice, respectively, compared to the NS. Concurrently, the hepatic HBV DNA levels decreased by 1.09, 0.24, and 2.03 log10 IU/mL. EA also demonstrated superior inhibition of HBV antigens, with serum HBeAg levels decreasing by 43.86%, 8.74%, and 8.03%, and serum HBsAg levels decreasing by 28.01%, 0.26%, and 9.39% in the EA, SE, and TF groups, respectively. Further analysis through transcriptomics and metabolomics revealed that EA's anti-HBV effects primarily hinge on immune modulation, particularly the IFN-γ/JAK/STAT pathway and taurine metabolism. EA also increased the ratio of splenic CD8+ CD69+ and CD8+ IFN-γ+ T-cells while upregulating key proteins in the JAK/STAT pathway and cytokines associated with antiviral immunity. Conclusion: EA manifests inhibitory effects on HBV, particularly in antigen suppression, with its mode of action intricately linked to the regulation of IFN-γ/JAK/STAT.

RESUMO

Background: Protective ileostomy can effectively prevent severe anastomotic leakage after rectal cancer surgery; however, the optimal timing for ileostomy closure during adjuvant chemotherapy remains unclear. This study aimed to explore the safety and long-term outcomes of early ileostomy closure during adjuvant chemotherapy. Method: Patients who underwent laparoscopic rectal cancer surgery combined with protective ileostomy and adjuvant chemotherapy between April 2017 and April 2021 were retrospectively evaluated. Patients were divided into an early closure group during chemotherapy (group A) and a late closure group after chemotherapy (group B). Results: A total of 215 patients were included in this study, with 115 in group A and 100 in group B. There were no significant differences in demographic and clinical characteristics between the two groups. In group A, durations of stoma status (p < 0.001) and low anterior resection syndrome (LARS) (p < 0.001) were shorter, and rectal stenosis (p=0.036) and stoma-related complications (p=0.007), especially stoma stenosis (p=0.041), were less common. However, compliance with chemotherapy was worse (p=0.009). There were no significant differences in operative time, postoperative hospital stay, postoperative complications, incidence and severity of LARS, disease-free survival, or overall survival between groups. Conclusion: Early ileostomy closure can effectively reduce the duration of stoma status, duration of LARS, rectal stenosis, and stoma-related complications while not affecting surgical complications and oncological outcomes. Ileostomy closure should not be delayed because of adjuvant chemotherapy. However, follow-up should be strengthened to increase compliance and integrity with chemotherapy.

RESUMO

Background: To improve perioperative frailty status in patients undergoing laparoscopic colorectal cancer surgery (LCCS), we explored a new intensive prehabilitation program that combines prehabilitation exercises with standard enhanced recovery after surgery (ERAS) and explored its impact. Methods: We conducted a prospective randomized controlled trial. Between April 2021 to August 2021, patients undergoing elective LCCS were randomized into the standardized ERAS (S-ERAS) group or ERAS based on prehabilitation (group PR-ERAS). Patients in the PR-ERAS group undergoing prehabilitation exercises in the perioperative period in addition to standard enhanced recovery after surgery. We explored the effects of this prehabilitation protocol on frailty, short-term quality of recovery (QoR), psychological status, postoperative functional capacity, postoperative outcomes, and pain. Results: In total, 125 patients were evaluated, and 95 eligible patients were enrolled and randomly allocated to the S-ERAS (n = 45) and PR-ERAS (n = 50) groups. The Fried score was higher in the PR-ERAS group on postoperative day (7 (2(2,3) vs. 3(2,4), P = 0.012). The QoR-9 was higher in the PR-ERAS group than in the S-ERAS group on the 1st, 2nd, 3rd, and 7th postoperative days. The PR-ERAS group had an earlier time to first ambulation (P < 0.050) and time to first flatus (P < 0.050). Conclusion: Prehabilitation exercises can improve postoperative frailty and accelerate recovery in patients undergoing LCCS but may not improve surgical safety. Therefore, better and more targeted prehabilitation recovery protocols should be explored. Clinical trial registration: www.clinicaltrials.org , identifier NCT04964856.

RESUMO

Background: Sleep traits have been linked to diseases; particularly, their impact on cancer has received increasing attention. This study aimed to investigate whether sleep traits have a causal relationship with colorectal cancer (CRC) using two-sample Mendelian randomization (TSMR). Methods: Genetic instrumental variables (IVs) for seven sleep traits (sleep duration, ease of getting up in the morning, morning chronotype, daytime napping, insomnia symptoms, snoring, and daytime dozing) were selected from pooled data from published genome-wide association studies (GSWSs). Two-sample multivariate Mendelian randomization (MR) analyses were conducted to assess the causal association between sleep traits and CRC. Reverse MR analyses were performed to determine the causal relationship between CRC and sleep traits. Inverse variance weighted (IVW), MR-Egger, and weighted medians were calculated for all MR analyses. Results: The multivariable MR (MVMR) analysis found that appropriate sleep duration [odds ratio (OR) =0.989; 95% confidence interval (CI): 0.980, 0.999; P=0.04] and ease of getting up in the morning (OR =0.990; 95% CI: 0.980, 1.000; P=0.04) were protective factors for CRC. Snoring (OR =1.021; 95% CI: 1.002, 1.041; P=0.03) was associated with the risk of CRC. Ease of getting up in the morning (OR =0.990; 95% CI: 0.983, 0.997; P=0.003) was associated with reduced risk of colon cancer. Morning chronotype (OR =1.004; 95% CI: 1.000, 1.007; P=0.04) was associated with the risk of colon cancer. Insomnia symptoms (OR =0.995; 95% CI: 0.990, 0.999; P=0.03) were a protective factor for rectal cancer. There was no evidence found for a causal association between other sleep traits and CRC, colon, or rectal cancer. Conclusions: Proper sleep duration and ease of getting up in the morning may be protective factors against CRC, and snoring may increase the risk of CRC.
