ABSTRACT

Objective To explore the safety and feasibility of single-segment paravertebral nerve block(PVNB)in elderly patients undergoing inguinal hernioplasty.Methods A retrospective analysis was made on clinical data of 58 elderly patients who underwent open tension-free inguinal hernioplasty from January 2016 to December 2022.According to the anesthesia method,they were divided into two groups with 29 cases in each:single-segment PVNB group(P group)and single subarachnoid block group(S group).Patients in the P group were given L1 single-segment PVNB guided by ultrasound combined with peripheral nerve stimulators or simple peripheral nerve stimulators by using 0.4%ropivacaine 20 ml.Patients in the S group underwent puncture in the interspinous space between L3/4 and received 0.5%bupivacaine 10 mg.The mean arterial pressure and heart rate before anesthesia(T0),at the time of skin incision(T1),at the time of hernia sac dissection(T2),and at the time of wound closure(T3)were recorded,and the block levels,anesthetic effect,remedial rate of fentanyl,local anesthetic toxicity,peripheral nerve injury,urinary retention,delirium,and nausea and vomiting of the patients were recorded.The patient's satisfaction with anesthesia was followed up.Results All the 58 patients underwent surgery smoothly.The difference in block levels was statistically significant between the two groups of patients(Z =-4.144,P =0.000),while the differences in the remedial rate of fentanyl,anesthesia effect,and anesthesia satisfaction were not statistically significant(χ2 =0.269,P =0.604;Z =-1.430,P =0.153;Z =-1.395,P =0.163).There were no statistically significant differences in mean arterial pressure and heart rate changes between the two groups at different time points(F =0.002,P = 0.960;F =0.260,P =0.612).The rate of urinary retention in the P group was significantly lower than that in the S group(0.0%vs.24.1%,Fisher's test,P =0.010).There were no statistically significant differences in rates of dilirium and nausea and vomitting(P>0.05).All the patients did not experience local anesthetic toxicity or peripheral nerve injury during the perioperative period.Conclusion Single-segment PVNB can provide comprehensive anesthesia and analgesia for elderly patients undergoing inguinal hernioplasty,helping to maintain the stability of intraoperative hemodynamics and reducing the risk of postoperative adverse reactions.

ABSTRACT

@#Abstract: Olfactory receptors (ORs) are transmembrane proteins mainly distributed in olfactory sensory neurons of the nasal epithelium, mediating the transmission of real-time sensory signals to the brain to produce smell. Recent studies have reported that ORs can also be expressed in tissues or organs outside the nasal cavity, and are closely related to a variety of biological processes, such as sperm chemotaxis, wound healing, glycolipid metabolism and intestinal secretion. In addition, ORs are closely related to a variety of malignant tumors such as prostate cancer, breast cancer and colorectal cancer, and may affect the occurrence and development of tumors by regulating cell proliferation, apoptosis, migration and invasion. This review provides an overview of the effects of ectopic ORs on the function of various human tissues and organs and assesses their potential value as drug targets for the treatment of human diseases.

ABSTRACT

A major impedance to neuronal regeneration after peripheral nerve injury(PNI)is the activation of various programmed cell death mechanisms in the dorsal root ganglion.Ferroptosis is a form of pro-grammed cell death distinguished by imbalance in iron and thiol metabolism,leading to lethal lipid peroxidation.However,the molecular mechanisms of ferroptosis in the context of PNI and nerve regeneration remain unclear.Ferroportin(Fpn),the only known mammalian nonheme iron export protein,plays a pivotal part in inhibiting ferroptosis by maintaining intracellular iron homeostasis.Here,we explored in vitro and in vivo the involvement of Fpn in neuronal ferroptosis.We first delineated that reactive oxygen species at the injury site induces neuronal ferroptosis by increasing intracellular iron via accelerated UBA52-driven ubiquitination and degradation of Fpn,and stimulation of lipid peroxidation.Early administration of the potent arterial vasodilator,hydralazine(HYD),decreases the ubiquitination of Fpn after PNI by binding to UBA52,leading to suppression of neuronal cell death and significant ac-celeration of axon regeneration and motor function recovery.HYD targeting of ferroptosis is a promising strategy for clinical management of PNI.

ABSTRACT

Objective To establish a solvent desorption inductively coupled plasma-mass spectrometry (ICP-MS) method for determination of iodine in workplace air. Methods Iodine in workplace air was collected with alkaline activated carbon tube and desorbed with 10.0 mL pure water or 20 mmol/L sodium bicarbonate solution. Rhenium-185 was used as an internal standard for quantification. The sample was determined in standard mode and kinetic energy discrimination collision (KED) mode by ICP-MS. Results In standard mode, iodine showed a good linear range in the concentration of 9.0 to 1 100.0 μg/L, with a correlation coefficient of 0.999 3 and a detection limit of 2.7 μg/L. In KED mode, iodine showed a good linear range in the concentration of 24.3 to 800.0 μg/L, with a correlation coefficient of 0.999 1 and a detection limit of 7.3 μg/L. The average desorption efficiency using pure water ranged from 99.1% to 106.7%, with within-run relative standard deviation (RSD) of 3.1% to 8.0% and between-run RSD of 4.9% to 9.3%. The average desorption efficiency using sodium bicarbonate solution ranged from 96.5% to 105.3%, with within-run RSD of 4.9% to 8.6% and between-run RSD of 2.5% to 9.9%. There were no statistical significant differences in the main effects of desorption solution, ICP-MS detection mode, their interaction on average desorption efficiency and within-run RSD (all P>0.05). Samples could be stored at room temperature for at least 7 days. Conclusion This method is highly sensitive, accurate, and suitable for the determination of iodine in workplace air.

ABSTRACT

Objective: To compare the impact of different prognostic scores in patients with acute-on-chronic liver failure (ACLF) in order to provide treatment guidance for liver transplantation. Methods: The information on inpatients with ACLF admitted at Beijing You'an Hospital Affiliated to Capital Medical University and the First Affiliated Hospital of Zhejiang University School of Medicine from January 2015 to October 2022 was collected retrospectively. ACLF patients were divided into liver transplantation and non-liver transplantation groups, and the two groups prognostic conditions were followed-up. Propensity score matching was carried out between the two groups on the basis of liver disease (non-cirrhosis, compensated cirrhosis, and decompensated cirrhosis), the model for end-stage liver disease incorporating serum sodium (MELD-Na), and ACLF classification as matching factors. The prognostic condition of the two groups after matching was compared. The difference in 1-year survival rate between the two groups was analyzed under different ACLF grades and MELD-Na scores. The independent sample t-test or rank sum test was used for inter-group comparison, and the χ (2) test was used for the comparison of count data between groups. Results: In total, 865 ACLF inpatients were collected over the study period. Of these, 291 had liver transplantation and 574 did not. The overall survival rates at 28, 90, and 360 days were 78%, 66%, and 62%, respectively. There were 270 cases of matched ACLF post-liver transplantation and 270 cases without ACLF, in accordance with a ratio of 1:1. At 28, 90, and 360 days, patients with non-liver transplantation had significantly lower survival rates (68%, 53%, and 49%) than patients with liver transplantation (87%, 87%, and 78%, respectively; P < 0.001). Patients were classified into four groups according to the ACLF classification criteria. Kaplan-Meier survival analysis showed that the survival rates of liver transplantation and non-liver transplantation patients in ACLF grade 0 were 77.2% and 69.4%, respectively, with no statistically significant difference (P = 0.168). The survival rate with an ACLF 1-3 grade was significantly higher in liver transplantation patients than that of non-liver transplantation patients (P < 0.05). Patients with ACLF grades 1, 2, and 3 had higher 1-year survival rates compared to non-liver transplant patients by 50.6%, 43.6%, and 61.7%, respectively. Patients were divided into four groups according to the MELD-Na score. Among the patients with a MELD-Na score of < 25, the 1-year survival rates for liver transplantation and non-liver transplantation were 78.2% and 74.0%, respectively, and the difference was not statistically significant (P = 0.149). However, among patients with MELD-Na scores of 25-30, 30-35, and≥35, the survival rate was significantly higher in liver transplantation than that of non-liver transplantation, and the 1-year survival rate increased by 36.4%, 54.9%, and 62.5%, respectively (P < 0.001). Further analysis of the prognosis of patients with different ACLF grades and MELD-Na scores showed that ACLF grades 0 or 1 and MELD-Na score of < 30 had no statistically significant difference in the 1-year survival rate between liver transplantation and non-liver transplantation (P > 0.05), but in patients with MELD-Na score≥30, the 1-year survival rate of liver transplantation was higher than that of non-liver transplantation patients (P < 0.05). In the ACLF grade 0 and MELD-Na score of≥30 group, the 1-year survival rates of liver transplantation and non-liver transplantation patients were 77.8% and 25.0% respectively (P < 0.05); while in the ACLF grade 1 and MELD-Na score of≥30 group, the 1-year survival rates of liver transplantation and non-liver transplantation patients were 100% and 20.0%, respectively (P < 0.01). Among patients with ACLF grade 2, the 1-year survival rate with MELD-Na score of < 25 in patients with liver transplantation was 73.9% and 61.6%, respectively, and the difference was not statistically significant (P > 0.05); while in the liver transplantation patients group with MELD-Na score of ≥25, the 1-year survival rate was 79.5%, 80.8%, and 75%, respectively, which was significantly higher than that of non-liver transplantation patients (36.6%, 27.6%, 15.0%) (P < 0.001). Among patients with ACLF grade 3, regardless of the MELD-Na score, the 1-year survival rate was significantly higher in liver transplantation patients than that of non-liver transplantation patients (P < 0.01). Additionally, among patients with non-liver transplantation with an ACLF grade 0~1 and a MELD-Na score of < 30 at admission, 99.4% survived 1 year and still had an ACLF grade 0-1 at discharge, while 70% of deaths progressed to ACLF grade 2-3. Conclusion: Both the MELD-Na score and the EASL-CLIF C ACLF classification are capable of guiding liver transplantation; however, no single model possesses a consistent and precise prediction ability. Therefore, the combined application of the two models is necessary for comprehensive and dynamic evaluation, but the clinical application is relatively complex. A simplified prognostic model and a risk assessment model will be required in the future to improve patient prognosis as well as the effectiveness and efficiency of liver transplantation.

ABSTRACT

Background@#There is no standard cut-off value of serum IgG4 concentration and serum IgG4/total IgG ratio for the diagnosis of IgG4-related disease (IgG4-RD) or as a marker of treatment responses. We aimed to explore this issue through a retrospective cohort analysis of adults in southwest China. @*Methods@#The diagnostic performance of serum IgG4 concentration and IgG4/IgG ratio for IgG4-RD was evaluated in a retrospective analysis of 177 adults newly diagnosed as having IgG4-RD and 877 adults without IgG4-RD. Dynamic analysis was performed to evaluate the significance of serum IgG4 concentration on IgG4-RD treatment responses. @*Results@#The serum IgG4 concentration differed according to sex. The optimal cut-off values of serum IgG4 concentration and IgG4/IgG ratio for IgG4-RD diagnosis were 1.92 g/L and 0.12 in males and 1.83 g/L and 0.11 in females, respectively. For patients with serum IgG4 concentration >2.01 g/L, the cut-off values in the total population were >3.00 g/L and 0.19, respectively. The median serum IgG4 concentration decreased over time, and the decrease rate increased over time. The serum IgG4 concentration significantly decreased at >1 week post-treatment (P=0.004), and the median decrease rate was close to 50% at >4 weeks post-treatment. @*Conclusions@#Serum IgG4 can be a good indicator for IgG4-RD diagnosis; however, different diagnostic cut-off values should be determined according to sex. The decreasing rate is more conducive than the serum IgG4 concentration to monitor treatment efficacy. The IgG4/IgG ratio did not improve the diagnostic efficacy for IgG4-RD.

ABSTRACT

Background In mainland China, patients with neovascular age-related macular degeneration (nAMD) have approximately an 40% prevalence of polypoidal choroidal vasculopathy (PCV). This disease leads to recurrent retinal pigment epithelium detachment (PED), extensive subretinal or vitreous hemorrhages, and severe vision loss. China has introduced various treatment modalities in the past years and gained comprehensive experience in treating PCV.Methods A total of 14 retinal specialists nationwide with expertise in PCV were empaneled to prioritize six questions and address their corresponding outcomes, regarding opinions on inactive PCV, choices of anti-vascular endothelial growth factor (anti-VEGF) monotherapy, photodynamic therapy (PDT) monotherapy or combined therapy, patients with persistent subretinal fluid (SRF) or intraretinal fluid (IRF) after loading dose anti-VEGF, and patients with massive subretinal hemorrhage. An evidence synthesis team conducted systematic reviews, which informed the recommendations that address these questions. This guideline used the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach to assess the certainty of evidence and grade the strengths of recommendations. Results The panel proposed the following six conditional recommendations regarding treatment choices. (1) For patients with inactive PCV, we suggest observation over treatment. (2) For treatment-na?ve PCV patients, we suggest either anti-VEGF monotherapy or combined anti-VEGF and PDT rather than PDT monotherapy. (3) For patients with PCV who plan to initiate combined anti-VEGF and PDT treatment, we suggest later/rescue PDT over initiate PDT. (4) For PCV patients who plan to initiate anti-VEGF monotherapy, we suggest the treat and extend (T&E) regimen rather than the pro re nata (PRN) regimen following three monthly loading doses. (5) For patients with persistent SRF or IRF on optical coherence tomography (OCT) after three monthly anti-VEGF treatments, we suggest proceeding with anti-VEGF treatment rather than observation. (6) For PCV patients with massive subretinal hemorrhage (equal to or more than four optic disc areas) involving the central macula, we suggest surgery (vitrectomy in combination with tissue-plasminogen activator (tPA) intraocular injection and gas tamponade) rather than anti-VEGF monotherapy. Conclusions Six evidence-based recommendations support optimal care for PCV patients' management.

ABSTRACT

Gastrointestinal mucositis is one of the most debilitating side effects of the chemotherapeutic agent irinotecan (CPT-11). Andrographolide, a natural bicyclic diterpenoid lactone, has been reported to possess anti-colitis activity. In this study, andrographolide treatment was found to significantly relieve CPT-11-induced colitis in tumor-bearing mice without decreasing the tumor suppression effect of CPT-11. CPT-11 causes DNA damage and the release of double-stranded DNA (dsDNA) from the intestine, leading to cyclic-GMP-AMP synthase (cGAS)‒stimulator of interferon genes (STING)-mediated colitis, which was significantly decreased by andrographolide both in vivo and in vitro. Mechanistic studies revealed that andrographolide could promote homologous recombination (HR) repair and downregulate dsDNA‒cGAS‒STING signaling and contribute to the improvement of CPT-11-induced gastrointestinal mucositis. These results suggest that andrographolide may be a novel agent to relieve gastrointestinal mucositis caused by CPT-11.

ABSTRACT

Objective:To investigate the application value of Hisense computer-assisted surgery system (CAS) three-dimensional reconstruction in the precision treatment of pediatric liver tumors.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 82 children with liver tumors who were admitted to Affiliated Hospital of Qingdao University from January 2013 to September 2021 were collected. There were 39 males and 43 females, aged 13(19)months. Children underwent upper abdominal dynamic enhanced computed tomography (CT) examination, and three-dimensional reconstruction was performed on CT images of arterial, equili-brium and venous phases with Hisense CAS. Surgical feasibility and scheme were evaluated and conducted based on the results of upper abdominal dynamic enhanced CT examination, and then revised according to three-dimensional reconstruction results of Hisense CAS. Observation indicators: (1) comparison of surgical scheme between two-dimensional enhanced CT images and three-dimensional reconstruction results of Hisense CAS; (2) intraoperative and postoperative situations; (3) follow-up. Follow-up was conducted by outpatient examination to detect postoperative compli-cations and residual liver compensation up to November 2021. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(IQR) or M(range). Count data were described as absolute numbers or percentages. Results:(1) Comparison of surgical scheme between two-dimensional CT images and three-dimensional reconstruction results of Hisense CAS. ① Based on the two-dimensional CT images, 42 cases of 82 children could undergo one-stage resection and 40 children could not. However, based on the three-dimensional reconstruction results of Hisense CAS, 48 cases of 82 children could undergo one-stage resection and 34 children could not. There were 6 children with one-stage resection feasibility based on the three-dimensional reconstruction results of Hisense CAS rather than the two-dimensional CT images. For the 34 children undergoing chemotherapy firstly, 31 cases had surgical feasibility after chemotherapy based on the two-dimensional CT images and 3 cases could not undergo surgery because of unapparent tumor regression or tumor surrounding impor-tant vessels. However, the 34 children had surgical feasibility after chemotherapy based on the three-dimensional reconstruction results of Hisense CAS. The revision rate of surgical feasibility was 11.0%(9/82) for the 82 children. ② Based on the two-dimensional CT images, 15 cases of 82 children underwent liver left lobectomy, 21 cases underwent liver right lobectomy, 7 cases underwent mesohepatectomy, 13 cases underwent extended left hemihepatectomy, 23 cases underwent extended right hemihepatectomy, 3 cases underwent segmental hepatectomy. However, based on the three-dimensional reconstruction results of Hisense CAS, 20 cases of 82 children underwent liver left lobectomy, 29 cases underwent liver right lobectomy, 7 cases underwent mesohepatectomy, 7 cases underwent extended left hemihepatectomy, 14 cases underwent extended right hemihepatectomy, 5 cases underwent segmental hepatectomy. The revision rate of surgical scheme was 36.6%(30/82) for the 82 children. (2) Intraoperative and postoperative situations. The operation time, volume of intraoperative blood loss, duration of postoperative hospital stay of the 82 children were (182±18)minutes, 20(10)mL, (10.2±1.9)days, respectively. (3) Follow-up. All the 82 children were followed up for 10 (range, 2?18)months. There was no obvious complication occurred to the 82 children after surgery, and the residual liver can satisfy the liver compensation of body. All the children survived well.Conclusion:Three-dimensional reconstruction of Hisense CAS is conducive to judging the surgical feasibility and formulation of accurate surgical plan of children with liver tumors.

ABSTRACT

Objective@#To analyze the prevalence of dry and wet age-related macular degeneration (AMD) in patients with diabetes, hypertension and hyperlipidemia, and to analyze the risk factors for AMD.@*Methods@#A population-based cross-sectional epidemiologic study was conducted involving 14,440 individuals. We assessed the prevalence of dry and wet AMD in diabetic and non-diabetic subjects and analyzed the risk factors for AMD.@*Results@#The prevalence of wet AMD in diabetic and non-diabetic patients was 0.3% and 0.5%, respectively, and the prevalence of dry AMD was 17% and 16.4%, respectively. The prevalence of wet AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 0.5%, 0.3%, 0.2%, and 0.7%, respectively. The prevalence of dry AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 16.6%, 16.2%, 15.2%, and 17.2%, respectively. Age, sex, body mass index, and use of hypoglycemic drugs or lowering blood pressure drugs were corrected in the risk factor analysis of AMD. Diabetes, diabetes/hypertension, diabetes/hyperlipidemia, and diabetes/hypertension/hyperlipidemia were analyzed. None of the factors analyzed in the current study increased the risk for the onset of AMD.@*Conclusion@#There was no significant difference in the prevalence of wet and dry AMD among diabetic and non-diabetic subjects. Similarly, there was no significant difference in the prevalence of wet and dry AMD among subjects with hypertension and hyperlipidemia. Diabetes co-existing with hypertension and hyperlipidemia were not shown to be risk factors for the onset of dry AMD.
