Sepsis involves a complex cascade of inflammatory reactions and immune system dysregulation. Neutrophils play a crucial role in modulating the anti-inflammatory response, which is vital for managing sepsis. Impaired chemotaxis of granulocytes can significantly impact the outcome of sepsis. Shenfu Decoction, by tonifying Qi and warming Yang, enhances the propelling function of Qi for promoting the chemotactic function of neutrophils. This study aimed to investigate the effects of Shenfu Decoction on the chemotactic function of neutrophils in septic mice and the underlying mechanisms.

Thirty 10-week-old specific-pathogen-free male C57BL/6J mice were randomly divided into five groups: sham operation, model, and low-, medium-, and high-dose Shenfu Decoction treatment groups (n = 6 in each group). Sepsis was induced using cecum ligation and puncture procedures. The sham-operated group served as the control. The drug was administered 6 h after surgery; the sham-operated and model groups received saline, while the treatment groups were gavaged every 12 h with the respective concentrations of Shenfu Decoction. Four hours after the last gavage, the mice were euthanized, and samples were collected to determine neutrophil counts and related indices. Primary neutrophils were extracted from the peripheral blood of septic mice and divided into blank control, sham-operated, low-dose, and high-dose groups. These cells were cultured with serum containing the respective treatments to measure neutrophil chemotactic distance, intracellular calcium ion concentration, and the expression levels of chemokine receptors and P2X1 receptors.

Compared with the sham-operated group, the total number of colonies and the number of neutrophils in the peritoneal lavage fluid were increased in the model group (P < 0.05). In the treatment groups, the number of neutrophils in the peritoneal lavage fluid was significantly increased (P < 0.05), while the number of neutrophils in the blood was decreased. Compared with the blank control group, the neutrophil chemotaxis distance was significantly prolonged in the sham-operated group. Additionally, the expression levels of P2X1 and FPR1 receptors were decreased, the expression levels of CXCR1 and CXCR2 receptors were increased (P < 0.05), and the calcium ion concentration was decreased (P > 0.05). Compared with the sham-operated group, the treatment groups exhibited a prolonged neutrophil chemotaxis distance, significantly decreased expression levels of P2X1 and FPR1 receptors, significantly increased expression levels of CXCR1 and CXCR2 receptors (P < 0.05), and significantly decreased calcium ion concentrations (P < 0.05). These effects were positively correlated with the Shenfu Decoction dosage.

Shenfu Decoction can improve the chemotactic function of neutrophils, possibly through the downregulation of P2X1 receptor expression. Its effects are positively correlated with the dosage.

Chronic obstructive pulmonary disease (COPD) is an irreversible inflammatory lung disease. Studies have shown that macrophages and estrogen receptors play a pivotal regulatory role in the development of COPD. Ejiao (Colla Corii Asini, CCA, or donkey-hide gelatin), a traditional Chinese medicine, has anti-inflammatory and lung function-protective effects, but its specific mechanism in COPD remains unclear. This study aimed to explore the immunomodulatory effects of Ejiao on COPD, focusing on its impact on inflammatory pathways and macrophages.

This study is the first to apply a network pharmacology approach to explore the potential mechanisms underlying Ejiao’s therapeutic effects on COPD. We collected the peptides and chemical components of Ejiao and used the STRING database to screen for COPD-related targets of Ejiao components, constructing a drug-molecular network. Additionally, we established cigarette smoke extract (CSE) and lipopolysaccharide-induced cell injury models and treated them with Ejiao-containing serum. Western blot (WB) analysis was used to detect the expression of related proteins, enabling a preliminary exploration of Ejiao’s effects and regulatory mechanisms. In further experiments, a mouse COPD model was established, and eight weeks of Ejiao intervention were conducted. We assessed lung function, pathological changes in lung tissue, monitored cytokine levels in serum and bronchoalveolar lavage fluid, performed flow cytometry to evaluate abdominal macrophage levels, and conducted WB to analyze protein expression, providing an in-depth study of Ejiao’s regulatory effects on the mouse COPD model.

The findings from the network pharmacology analysis suggest a potential regulatory role of the estrogen receptor pathway in COPD. CSE stimulation of RAW264.7 cells resulted in elevated tumor necrosis factor-α levels, decreased interleukin-10 levels, reduced expression of estrogen receptors (ERs) α and β, decreased inhibitor of NF-κB levels, and increased p-AKT levels. Following Ejiao intervention, interleukin-10, ERα+β, and inhibitor of NF-κB levels increased, while p-AKT levels decreased. Ejiao significantly improved lung function in CSE/lipopolysaccharide-induced COPD mice, reduced the number of macrophages, lowered the levels of inflammatory factors in bronchoalveolar lavage fluid, and increased estradiol levels in serum. WB results indicated that Ejiao may ameliorate lung injury in COPD by modulating the ER/AKT/NF-κB pathway.

The results suggest that Ejiao may improve lung injury and inflammation in CSE/ lipopolysaccharide-induced COPD by regulating the ER/AKT/NF-κB pathway.

Gastrointestinal dysmotility commonly follows thermal injuries, such as burns. This study aimed to investigate the effects and mechanisms of electroacupuncture (EA) on burn-induced gastric dysmotility in rats.

Sprague-Dawley rats were divided into sham and thermal injury groups subjected to a 60% scald burn. Antagonists, including β-blockade (propranolol), α-blockade (phentolamine), or a selective cyclooxygenase (COX)-2 inhibitor (nimsulide), were administered to verify the pathways involved. Six hours after the burn, the animals were evaluated for gastric emptying and heart rate variability. Blood and gastric tissues were collected for assays of cytokines, hormones, and COX-2 levels. EA was performed at bilateral ST36 (Zusanli) acupoints for 45 m.

Burn injury delayed gastric emptying by 61% (P < 0.01), which was normalized by nimsulide or propranolol but not by phentolamine. EA improved gastric emptying by 87% (P = 0.03) in burned rats. Heart rate variability and plasma hormone (noradrenaline and pancreatic polypeptide) analyses indicated sympathetic hyperactivity in burned rats; EA improved burn-induced sympathovagal imbalance by enhancing vagal activity. Protein and mRNA expressions of COX-2 in the gastric fundus and antrum increased with burn but were normalized by propranolol. EA reduced the burn-induced increase in COX-2 expression in the gastric fundus but not in the antrum. EA also decreased burn-induced elevations in plasma interleukin (IL)-6 and IL-10. Negative correlations were found between gastric emptying and plasma IL-6 levels, as well as between gastric emptying and COX-2 mRNA levels.

These findings suggest that burn-induced gastric dysmotility is mediated via autonomic-COX-2 pathways. EA at acupoint ST36 improves burn-induced delays in gastric emptying by down-regulating COX-2 and pro-inflammatory cytokines through the autonomic nervous pathway.

Hepatocellular carcinoma (HCC) represents the most prevalent malignancy in Egypt and globally. However, non-invasive diagnostic/prognostic biomarkers for early detection of HCC are still lacking. Circular RNAs (circRNAs) are one of the promising biomarkers. They are considered stable, long-stranded non-coding RNAs in a sealed circular form held together by covalent bonds. circRNAs have been observed in several genetic studies to play a vital role in the initiation and progression of malignancy. Our current cross-sectional study aimed to evaluate the potential role of serum-derived hsa_circ_101555 as a diagnostic biomarker for HCC, in addition to comparing its prognostic significance and predicting the response to therapy.

The serum expression level of hsa_circ_101555 was measured using real-time polymerase chain reaction in 62 clinically/radiologically diagnosed Egyptian HCC patients at baseline and three months after HCC treatment. These results were compared to those of 30 healthy subjects.

Our data showed that the mean circRNA value was highest in HCC cases (7.66 ± 3.74) compared to healthy controls (1.21 ± 0.96). Furthermore, the circRNA value showed excellent diagnostic accuracy in differentiating HCC patients from healthy controls at a cutoff point of 1.966, as indicated by an area under the curve of 0.984. In addition, it showed a prognostic role in differentiating between HCC progression and regression in these patients based on response evaluation criteria in solid tumors (RECIST)/ modified- RECIST (mRECIST) response categories at the cutoff point 5.1150, with an area under the curve of 0.891 and a standard error of 0.058. Interestingly, positive correlations between post-intervention circRNA levels and laboratory measurements were observed in our HCC patients, including the albumin-bilirubin score (r = 0.424, P = 0.001**), the neutrophil-to-lymphocyte ratio (r = 0.410, P = 0.001**), alpha-fetoprotein (r = 0.273, P = 0.032*), the aspartate aminotransferase/alanine aminotransferase ratio (r = 0.284, P = 0.025*), fibrosis-4 (r = 0.501, P = 0.000**), and the aspartate aminotransferase to platelet ratio score (r = 0.436, P = 0.000**), indicating an association with worsening liver inflammation, fibrosis, and disease progression. Lastly, post-intervention circRNA values were significantly correlated with clinical/pathological tumor key features, including larger tumors (>5 cm) (P = 0.019), multiplicity (tumor numbers > 3) (P = 0.031), vascular invasion (P = 0.030), Barcelona Clinic Liver Cancer stage C (P = 0.007), and advanced Tomur, Node, Metastasis stage (P = 0.012).

To our knowledge, this is the first study to highlight the expression levels of serum-derived hsa_circ_101555 in Egyptian HCC patients. Our data showed its upregulation in HCC cases compared to healthy subjects. Additionally, its increased levels were associated with tumor progression according to the RECIST/mRECIST categories. Furthermore, its significant correlation with markers/scores of liver inflammation, dysfunction, and tumor pathological features underscores its potential as a promising diagnostic/prognostic biomarker, aiding in better clinical decision-making for the management of hepatocellular carcinoma.

This study investigates upper gastrointestinal tract (UGIT) involvement in patients with ulcerative colitis (UC), a condition traditionally considered limited to the colon. Although extra-colonic manifestations of UC are well recognized, UGIT issues have received less attention. This research aimed to document the clinical, endoscopic, and histopathological UGIT findings in adults with UC and assess their association with disease severity and extent.

This descriptive cross-sectional study was conducted at Ain Shams University over one year. A total of 78 UC patients underwent comprehensive clinical evaluations, including assessments of gastrointestinal complaints, medication history, disease progression, surgeries, and physical examinations. Endoscopic assessments of both the UGIT and colon were performed, accompanied by biopsies for histopathological analysis.

The study population had a mean age of 35.26 years, with a nearly equal gender distribution. Endoscopic findings revealed significant UGIT involvement: 64% of patients had esophagitis and/or gastroesophageal reflux disease, 93% had gastritis, and 80% had duodenitis. Histopathological findings showed notable inflammation, basal cell hyperplasia, and ulcerations in the esophagus, with 51.3% of patients exhibiting chronic gastritis and 38.5% testing positive for Helicobacter pylori infection. Statistical analysis demonstrated a strong association between colonic disease severity and UGIT endoscopic (p < 0.0001 and p < 0.001 in the esophagus and stomach, respectively) and histopathological (p < 0.004, p < 0.001, and p <0.005 in the esophagus, stomach, and duodenum, respectively) findings, particularly in patients with UGIT symptoms.

This study concludes that UGIT endoscopic and histopathological changes are prevalent among Egyptian UC patients, suggesting a significant link between UC and these UGIT findings.

Direct-acting antivirals (DAAs) have dramatically changed the landscape of chronic hepatitis C virus (HCV) treatment and significantly reduced the risk of HCV-related hepatocellular carcinoma (HCC) after achieving sustained virologic response. However, the risk of HCC persists, particularly in patients with pre-treatment cirrhosis or fibrosis stage 3 (F3), even after DAA-induced viral eradication. While professional guidelines agree on the need for surveillance in cirrhotic patients, there is no consensus regarding surveillance for the pre-treatment F3 population following HCV eradication. The risk of HCC in the F3 population falls below the threshold for cost-effective surveillance. However, co-existing risk factors—such as diabetes, hepatic steatosis, alcohol use, advanced age, and elevated alpha-fetoprotein levels—may warrant reconsideration of HCC surveillance in this group. This underscores the need for an individualized, risk-based approach to HCC surveillance. This review provided a simplified algorithm to assist clinicians in managing patients with HCV after DAA-induced sustained virologic response.

Surgical management of supratentorial spontaneous intracerebral hemorrhage (sICH) remains controversial. Craniotomy (CT) reduces mortality but offers limited functional benefits. Neuroendoscopic surgery (NE) has emerged as a viable alternative, providing improved outcomes. Recent randomized controlled trials (RCTs) strengthen ongoing comparisons between these approaches. This meta-analysis systematically evaluates the efficacy and safety of NE versus CT for supratentorial sICH.

RCTs comparing NE versus CT for supratentorial sICH were systematically identified through comprehensive searches of PubMed, Embase, Cochrane Library, and Web of Science databases. Evaluated outcomes included functional outcome (favorable or unfavorable), hematoma evacuation rate, mortality, intraoperative blood loss, operation time, rebleeding, infection (including pulmonary and intracranial), and total complications. Cochrane’s Risk of Bias-2 tool was employed to assess the risk of bias across the included studies.

Eight RCTs were included, comprising 1,354 patients. NE demonstrated a significant advantage in achieving a favorable functional outcome (risk ratio: 1.43; 95% confidence interval (CI) 1.22, 1.68; p < 0.001) and a notably higher hematoma evacuation rate (mean difference (MD): 7.60; 95% CI 3.59, 11.61; p < 0.001). Additionally, NE was associated with a marked reduction in intraoperative blood loss (MD: −152.95; 95% CI −261.68, −44.22; p = 0.006) and a substantial reduction in operative time (MD: −118.49; 95% CI −147.30, −89.67; p < 0.001). The incidences of unfavorable functional outcome and total complications, including pulmonary infection, were significantly lower in the NE group. However, NE did not lead to an improvement in the mortality rate, and there were no significant differences in the incidences of postoperative rebleeding or intracranial infection between the two groups.

These findings suggest that NE offers distinct advantages in terms of functional outcomes and surgical efficiency for patients with supratentorial sICH. Future studies should involve larger, higher-quality RCTs, and neuroendoscopic techniques should be continuously optimized.
