Retroperitoneal lymphangioma is exceptionally rare. We present a case of a 41-year-old asymptomatic patient with a large abdominal cystic mass detected on contrast-enhanced computed tomography (CT) scan, initially suspected to be pseudomyxoma peritonei. Laparoscopic exploration revealed a 30 x 30 cm multilocular cystic tumour originating from the retroperitoneum. The tumour was successfully resected laparoscopically, and pathological analysis confirmed a lymphangioma. The patient recovered well with no recurrence over five years. For uncertain tumour types, transabdominal laparoscopic exploration should be prioritised. For treating retroperitoneal lymphangiomas with the origin in the retroperitoneum and a main body in the abdominal cavity, the transabdominal laparoscopic approach is a less invasive and effective treatment option.

Abstract Objective: This study mainly explores (2R,6R; 2S,6S)-HNK and its compounds whether there are antidepressant effects. Methods: Four HNK compounds were obtained from 2-(Chlorophenyl) Cyclopentylmethanone. Forced swimming test, locomotor sensitization test, and conditioned location preference test were used to screen the antidepressant activity of the synthesized target compounds. Results: In the case of 10 mg HNK treatment, compared with saline, the immobile time of mice in the HNK group, I5 group and I6 group at 1 h and 7 days had statistical significance. In the case of 10 mg HNK treatment, compared with saline, the immobile time of compound C and D groups in the glass cylinder area was significantly different. In the locomotor sensitization test, the movement distance of compound C and D groups on day 15 and day 7 mice increased significantly compared with the first day. In the conditioned place preference experiment, compound C and compound D induced conditioned place preference in mice compared with the Veh group. Conclusion: The results of the forced swimming test, locomotor sensitization test, and conditioned location preference test showed that compounds C and D may have certain anti-depressant activity. However, HNK exerts a rapid and significant antidepressant effect within 1 week, but the duration is short.

ABSTRACT This investigation focused on the application of microwave pyrolysis technology, utilizing metal oxide clay minerals as both catalysts and microwave absorbers, with the goal of enhancing resource utilization efficiency in the treatment of oily sludge. Experimental results demonstrated that incorporating metal oxide clay minerals into the microwave pyrolysis process at 2000 W power substantially improved the yield of pyrolysis oil and gas, while simultaneously optimizing the products’ chemical composition. This study elucidates, for the first time, the distinct catalytic roles of three metal oxide clay minerals—hematite (Fe2O3), apatite (P2O5), and corundum (Al2O3)—in the microwave pyrolysis process. The findings indicate that these catalysts effectively increase the proportion of light fractions in pyrolysis oil and significantly reduce the production of harmful gases.The composition of combustible gases (H2 + CH4 + CO) in the pyrolysis gases exhibited increases of 7.224 wt%, 2.831 wt%, and 18.895 wt% for hematite, apatite, and corundum, respectively, relative to the control group. Specifically, hematite markedly enhanced the gas yield, particularly the concentrations of H2 and CO, and improved the quality of the pyrolysis oil, thereby augmenting the sludge’s energy recovery value. Furthermore, apatite exhibited outstanding nitrogen removal efficacy during the pyrolysis process, contributing to a reduction in nitrogen content in the pyrolysis oil and consequently diminishing the associated environmental risks. technology absorbers sludge 200 products elucidates time mineralshematite Fe2O3, Fe2O3 FeO , Fe O (Fe2O3) P2O5, P2O5 PO P (P2O5) Al2O3in AlOin Al2O3 Al gasesThe H (H CH CO 7224 7 224 7.22 wt 2831 2 831 2.83 18895 18 895 18.89 respectively group Specifically sludges s value Furthermore risks 20 Fe2O (Fe2O3 P2O (P2O5 AlO Al2O 722 22 7.2 283 83 2.8 1889 1 89 18.8 (Fe2O (P2O 72 7. 28 8 2. 188 18.

Nuclear factor erythroid 2 (NF-E2)-related factor 2 (Nrf2) is a key transcription factor in the antioxidant response and is associated with various chronic diseases. The aim of this study was to explore the action of esculetin, a natural dihydroxy coumarin, on attenuating middle cerebral artery occlusion (MCAO) and reperfusion, and whether its effect is dependent on Nrf2 activation, as well as nuclear factor-kappa B (NF-κB) inhibition. Two doses of esculetin (20 and 40 mg/kg) were tested on rats with MCAO reperfusion. Neurological deficiency, oxidative stress, and pathological analyses were performed to evaluate its effect. An in vitro analysis was also used to confirm whether its action was dependent on the Nrf2/HO-1/NQO-1 pathway. Compared with MCAO reperfusion rats, esculetin improved infarct volume and increased normal-shaped neuron cells by decreasing tumor necrosis factor-alpha (TNF-α), interleukin (IL)-6, and IL-1β levels. The oxidative stress parameter malondialdehyde (MDA) decreased and the activity of superoxide dismutase (SOD) and glutathione/glutathione disulfide (GSH/GSSG) ratio increased after esculetin treatment. Moreover, esculetin inhibited NF-κB activation induced by MCAO. In vitro, hypoxia/reoxygenation (H/R) impaired the viability of rat neuron cells and esculetin showed a neuron protection effect on cells. Nrf2 inhibitor Brusatol inhibited the activation of Nrf2, heme oxygenase-1 (HO-1), and NAD(P)H quinone oxidoreductase 1 (NQO-1) caused by esculetin and abolished its protection effect. Esculetin protected cerebral neurons from ischemia-reperfusion injury by inhibiting NF-κB and Nrf2/HO-1/NQO-1 activation.

OBJECTIVE: The objective of this study was to examine whether the National Institute of Health Stroke Scale was associated with the short- and long-term prognosis of patients with acute ischemic stroke treated with intravenous thrombolysis. METHODS: A total of 247 patients with acute ischemic stroke admitted to the hospital from April 2019 to October 2020 were retrospectively selected as study subjects, and the immediate and long-term prognosis after thrombolysis was assessed using the modified Rankin Scale and divided into good prognosis group (119 cases) and poor prognosis group (128 cases) based on the effect of thrombolysis. Both groups were treated with alteplase, the National Institute of Health Stroke Scale of the two groups was compared, and the factors affecting the prognosis of acute ischemic stroke were analyzed. RESULTS: After intravenous thrombolysis, 24 h, and 7 days of treatment, the National Institute of Health Stroke Scale in the poor prognosis group was higher than those of patients in the good prognosis group, and the differences were statistically significant (p<0.05). The results of the multivariate analysis suggested that National Institute of Health Stroke Scale before treatment was an independent factor associated with the 3-month (OR: 1.068, 95%CI 1.015–1.123, p=0.011) and long-term poor prognosis (OR: 1.064, 95%CI 1.012–1.119, p=0.015) in patients with acute ischemic stroke receiving intravenous thrombolysis after adjustment of age, gender, body mass index, smoking, alcohol consumer, onset-to-door time, door-to-needle time, and imaging score. CONCLUSION: The National Institute of Health Stroke Scale could be a promising indicator for the prognosis, and active intervention is needed to improve the quality of life in patients with acute ischemic stroke.

Abstract Introduction: Long QT Syndrome (LQTS) is an inherited disease with an abnormal electrical conduction system in the heart that can cause sudden death as a result of QT prolongation. LQT2 is the second most common subtype of LQTS caused by loss of function mutations in the potassium voltage-gated channel subfamily H member 2 (KCNH2) gene. Although more than 900 mutations are associated with the LQTS, many of these mutations are not validated or characterized. Methods and results: Sequencing analyses of genomic DNA of a family with LQT2 identified a putative mutation. i.e., KCNH2(NM_000238.3): c.3099_3112del, in KCNH2 gene which appeared to be a definite pathogenic mutation. The family pedigree information showed a gender difference in clinical features and T-wave morphology between male and female patients. The female with mutation exhibited recurring ventricular arrhythmia and syncope, while two male carriers did not show any symptoms. In addition, T-wave in females was much flatter than in males. The female proband showed a positive reaction to the lidocaine test. Lidocaine injection almost completely blocked ventricular arrhythmia and shortened the QT interval by ≥30 ms. Treatment with propranolol, mexiletine, and implantation of cardioverter-defibrillators prevented the sustained ventricular tachycardia, ventricular fibrillation, and syncope, as assessed by a 3-year follow-up evaluation. Conclusions: A putative mutation c.3099_3112del in the KCNH2 gene causes LQT2 syndrome, and the pathogenic mutation mainly causes symptoms in female progeny.

Abstract Objective To compare the analgesic effect of intercostal nerve block (INB) with ropivacaine when given preventively or at the end of the operation in patients undergoing video-assisted thoracic surgery (VATS). Methods A total of 50 patients undergoing VATS were randomly divided into two groups. The patients in the preventive analgesia group (PR group) were given INB with ropivacaine before the intrathoracic manipulation combined with patient-controlled analgesia (PCA). The patients in the post-procedural block group (PO group) were administered INB with ropivacaine at the end of the operation combined with PCA. To evaluate the analgesic effect, postoperative pain was assessed with the visual analogue scale (VAS) at rest and Prince Henry Pain Scale (PHPS) scale at 6, 12, 24, 48, and 72 hours after surgery. Results At 6 h and 12 h post-surgery, the VAS at rest and PHPS scores in the PR group were significantly lower than those in the PO group. There were no significant differences in pain scores between two groups at 24, 48, and 72 hours post-surgery. Conclusion In patients undergoing VATS, preventive INB with ropivacaine provided a significantly better analgesic effect in the early postoperative period (at least through 12 h post-surgery) than did INB given at the end of surgery.

Abstract This study aims to investigate the effect and specific mechanism of Coix Seed Oil (CSO) on immune hepatic fibrosis in immune injury rats. In this study, healthy Wister rats were injected with porcine serum in order to establish hepatic fibrosis model. We choose the compound Sophora flavescens injection as the positive control drug. HE staining was used to observe the morphological and histological changes. HSC-T6 cells were cultured in vitro. MTT and AO/EB staining were used to detect the effect of CSO on the proliferation and apoptosis of HSC-T6 cells. The results shown that Coix seed oil significantly improved hepatic fibrosis of immune injury rats, and the degree of hepatic fibrosis in CSO group was significantly reduced. Intraperitoneal injection of 15 mg/kg, 30 mg/kg and 40 mg/kg significantly reduced the levels of serum ALT, AST, ALP, HA, LN, PIIINP and C-IV in rats (P < 0.01).), MTT assay showed that the cells proliferated well. The results of HE staining showed that Coix seed oil had a good therapeutic effect on immune-induced hepatic fibrosis in rats. AO/EB staining showed that 0.5 mg/mL CSO for 24 h and 0.1 mg/mL CSO for 48 h both significantly promoted the apoptosis of HSC-T6 cells. In conclusion, Coix seed oil has a significant therapeutic effect on immune hepatic fibrosis, and its molecular mechanism may be related to antagonizing cytokine TGF-β1, inhibiting the expression of TIMP-1, promoting collagen degradation, inhibiting the activation of hepatocyte and promoting the apoptosis of activated hepatic stellate cells.

Abstract Objective The neuroinflammatory reaction activated after the activation of microglia plays a critical role in the pathological mechanism of early brain injury after subarachnoid hemorrhage. The inhibitory effect of Puerarin on inflammatory response plays a protective effect against various diseases. The present study mainly explored whether Puerarin alleviates the inflammation after SAH by inhibiting the Notchl pathway. Methods: Rat SAH model was induced by internal carotid artery puncture. The content of brain edema was evaluated and assessed. Evans blue staining was used to detect the degree of blood-brain barrier damage. FJC staining was used to assess neuronal apoptosis. Western blot method was employed to detect the expressions of Notchl receptor and downstream factors to clarify the protective effect and specific mechanism of Puerarin on brain tissue after SAH. Results: Puerarin can attenuate the brain edema and blood-brain barrier damage caused by early brain injury within 72 h after SAH, reduce the contents of Ibal and CD68 positive microglia. Intraventricular injection of Notchl receptor blockers and Notchl siRNA can inhibit the activation of Notchl pathway after SAH, mitigate brain tissue edema, blood-brain barrier damage, and neuronal apoptosis, as well as inhibit the activation of microglia and the release of inflammatory factors. Puerarin can inhibit the activation of Notchl receptor and downstream pathways, and simultaneously increase the content of Botch in brain tissue. Conclusion: Puerarin can inhibit the activation of Notchl receptor through Botch factor, thereby inhibiting the neuroinflammatory reaction mediated by Notchl pathway, and finally improve the early neurological dysfunction after SAH.

Abstract Response surface methodology (RSM) was used to investigate the preparation-process parameters on calcium acetate from eggshell. Box-Behnken was employed for experimental design, and the optimal combination of reaction temperature, solid-liquid ratio, acetic acid concentration, primary reaction time and secondary reaction time for preparing calcium acetate was analyzed. Multiple regression analysis was used to fit the experimental data to the second-order polynomial equation, and appropriate statistical methods were used for analysis. The results showed that the optimum preparation conditions of calcium acetate were as follows: reaction temperature of 39 °C, solid-liquid ratio of 1:12, acetic acid concentration of 159%, primary reaction time 1.5 h and secondary reaction time of 80min. Under the optimum preparation conditions, the experimental yield of calcium acetate was 96.5%, which was in good agreement with the predicted value.

ABSTRACT Purpose: To assess the effect of continuously covering the sick eye affected with central serous chorioretinopathy for 48 h. Methods: This retrospective, case-control study involved 32 central serous chorioretinopathy patients categorized in the treatment group composed of 17 sick eye that received continuous covering treatment for 48 h with a medical gauze and the observation group composed of 15 of these patients who were followed up. None of the patients received any other treatments or medications. The logarithm of the minimal angle of resolution (logMAR) best-corrected visual acuity, macular retinal thickness, and the root mean square value of the amplitude density in the first ring of multifocal electroretinogram were examined before and after the 48-h treatment. Results: After the continuous treatment, the logMAR best-corrected visual acuities were 0.31 ± 0.18 and 0.56 ± 0.37 in the treatment and observation groups, respectively (p=0.019). The macular retinal thicknesses were 461 ± 43 µm and 498 ± 50 µm in the treatment and observation groups, respectively (p=0.032). The root mean square values of the amplitude density in the first ring of multifocal electroretinogram were 32.5 ± 5.3 nV/deg2 and 26.6 ± 4.3 nV/deg2 in the treatment and observation groups, respectively (p=0.002). Conclusions: The continuous application of the covering treatment for 48 h on the sick eye showed positive outcomes with respect to the best-corrected visual acuity, macular retinal thickness, and macular retina functions in the treatment of central serous chorioretinopathy.

ABSTRACT This study aimed to investigate the effect of Lactobacillus plantarum DPP8 and Lactobacillus acidophilus C7282 in feed supplementation on growth performance, Salmonella invasion, inflammation, and mediating signaling in broilers infected with Salmonella Typhimurium (S. Typhimurium). A total of 240 broilers at day old were randomly allocated into four groups, orally infected with S. Typhimurium and supplemented with individual or combined Lactobacilli DPP8 and C7282 at doses of 0 (control), 1010 (individual), or 2.0 × 1010 (combination) cfu/kg of diet for 21 d. The results showed that supplementing Lactobacilli improved (p<0.05) feed intake and body weight gain and decreased (p<0.05) S. Typhimurium load in the caecum, harder gland, spleen and bursa of Fabricius. Also, the supplements decreased (p<0.05) interleukin (1β/2/4), tumor necrosis factor α and interferon γ in the serum, enhanced (p<0.05) interleukin 10, and downregulated gene expressions of inflammatory mediators including Janus kinase (Jak2/3), signal transducer and activator of transcription protein (STAT3/4/5/6) in the intestinal mucosa. In contrast, diets containing DPP8 exhibited greater effects on the inhibition of the pathogen and inflammatory response than C7282. The obtained data suggest that Lactobacilli C7282 and DPP8 can be used as feed additives to inhibit colonization and translocation of S. Typhimurium and inflammatory responses via downregulating Jak/STAT signaling in broilers.
