Objective To observe the effect of Renshen(ginseng)-Yuzhu(fragrant solomonseal rhizome)on inflammatory factors and inflammasomes in depression rats,and to explore the antidepressant mechanism of Renshen-Yuzhu.Methods Fifty male SD rats were divided into the blank group,model group,fluoxetine group(2.1 mg/kg),Renshen-Yuzhu low-dose group(1.89 g/kg),and Renshen-Yuzhu high-dose group(5.67 g/kg),with ten rats in each group.Except for the blank group,the rats in the other groups were treated with chronic unpredictable mild stress to establish a depression rat model.On the second day after the end of modeling,the rats in each group were given the corresponding drugs once daily for 14 days.After modeling and dosing,body weight,forced swimming immobility time,and sucrose preference rate were measured.After dosing,hematoxylin-eosin staining was used to detect neuronal damage in the cerebral cortex,enzyme-linked immunosorbent assay was used to detect the contents of interleukin-4(IL-4),interleukin-23(IL-23),and interleukin-27(IL-27)in cortex,real-time PCR was used to detect the mRNA expression of interleukin-24(IL-24)in cortex,and the protein expressions of nucleotide-binding oligomerization domain-like receptor protein 1(NLRP1),absent in melanoma 2(AIM2),and nucleotide-binding oligomerization domain-like receptor protein 4(NLRC4)were detected by Western blotting.Results After dosing,compared with the blank group,the body weight of the model group decreased,the sucrose preference rate decreased,the swimming immobility time was prolonged,the neuronal tissue in cortex was destroyed,the content of IL-4 in cortex decreased,the contents of IL-23 and IL-27 in cortex increased,and the protein expressions of NLRP1,AIM2 and NLRC4 in cortex increased(P＜0.01).Compared with the model group,the body weight of rats in each administration group increased,the sucrose preference rate increased,the swimming immobility time was shortened,the damage of neuronal tissues in cortex improved,the content of IL-4 in cortex increased,the contents of IL-23 and IL-27 in cortex decreased,and the protein expressions of NLRP 1,AIM2 and NLRC4 in cortex decreased(P＜0.05).Conclusion Renshen-Yuzhu couplet medicines can improve the depressive-like behavior and exert antidepressant effect in chronic stress rats,and its mechanism may be related to the inhibition of NLRP 1,NLRC4,AIM2 inflammasome activation and its mediated inflammatory response in cortex,reducing pro-inflammatory cytokines,and increasing the level of antiinflammatory cytokines.

OBJECTIVETo investigate the surgical techniques and appropriate perioperative management for ensuring successful orthotopic liver transplantation (ROLT) in rats.

METHODSBased on the double-cuff technique of Kamada, we modified the surgical techniques of separation, perfusion and cold preservation of the donor liver, shearing and anastomosis of the suprahepatic vena cava with optimized postoperative infusion protocols and animal care.

RESULTSTwo hundred and seventy rats underwent ROLT and a learning curve of the success rate was built to reflect the improvement of techniques. The learning curve showed steep improvements over the exploration stage, breakthrough stage and maturation stage, and the success rates increased sharply over time (0%, 71.1%, and 94.5%, respectively) until finally reaching over 90%. The shearing and anastomosis of the suprahepatic vena cava remained the most critical and difficult techniques in ROLT modeling.

CONCLUSIONProficient microsurgical techniques and meticulous nursing can reduce postoperative complications, enhance operational success rate and extend the survival time after ROLT.

BACKGROUND: This study aimed to determine the reasons for conversion and elucidate the safety and efficacy of transition to tenofovir alafenamide/emtricitabine/bictegravir sodium (TAF/FTC/BIC) in highly active antiretroviral therapy (HAART)-experienced HIV-infected patients in real-world settings. METHODS: We conducted a retrospective cohort study. The treatment conversion rationales, safety, and effectiveness in 1684 HIV-infected patients with previous HAART experience who switched to TAF/FTC/BIC were evaluated at Beijing Ditan Hospital from September 2021 to Auguest 2022. RESULTS: Regimen simplification (990/1684, 58.79%) was the most common reason for switching, followed by osteoporosis or osteopenia (375/1684, 22.27%), liver dysfunction (231/1684, 13.72%), decline in tenofovir alafenamide/emtricitabine/elvitegravir/cobicistat (TAF/FTC/EVG/c) with food restriction (215/1684, 12.77%), virological failure (116/1684, 6.89%), and renal dysfunction (90/1684, 5.34%). In patients receiving non-nucleotide reverse transcriptase inhibitors (NNRTI)-containing regimens, lipid panel changes 1 year after switching indicated a difference of 3.27 ± 1.10 mmol/L vs . 3.40 ± 1.59 mmol/L in triglyceride ( P  = 0.014), 4.82 ± 0.74 mmol/L vs . 4.88 ± 0.72 mmol/L in total cholesterol ( P  = 0.038), 3.09 ± 0.70 mmol/L vs . 3.18 ± 0.66 mmol/L in low-density lipoprotein ( P  <0.001), and 0.99 ± 0.11 mmol/L vs . 0.95 ± 0.10 mmol/L in high-density lipoprotein ( P  <0.001). Conversely, among patients receiving booster-containing regimens, including TAF/FTC/EVG/c and lopinavir/ritonavir (LPV/r), lipid panel changes presented decreased trends. We also observed an improved trend in viral load suppression, and alanine transaminase (ALT), aspartate transaminase (AST), estimated glomerular filtration rate (eGFR), and serum creatinine levels after the transition ( P  <0.001). CONCLUSION The transition to TAF/FTC/BIC demonstrated good treatment potency. Furthermore, this study elucidates the motivations behind the adoption of TAF/FTC/BIC in real-world scenarios, providing clinical evidence supporting the stable conversion to TAF/FTC/BIC for HAART-experienced patients.

Objective:To compare the policies and literature on scope of nurse practice in various countries, so as to provide reference for optimizing the expansion of scope of nurse practice in China.Methods:Literature on nurse practice was systematically searched on PubMed, Web of Science, China National Knowledge Infrastructure, WanFang Data, and nursing policy organization websites in various countries. The search period was from database establishment to June 2023.Results:A total of 19 articles from six countries were included. There were elements such as registration types and requirements, practice methods, prescription authority, supervision departments, and relevant laws. The inspiration for the hierarchical management of nurses in China mainly included four aspects: improving the hierarchical registration and management system, clarifying the job responsibilities of nurses; guiding the reasonable flow of nursing talents, encouraging multi-site practice in nurses; cultivating nurses' prescription ability and granting them prescription authority; improving supervision and legal protection to ensure that nurses practiced in accordance with the law.Conclusions:It is urgent to expand the practice scope of the nursing team in our country, supplement grassroots medical and health talents, undertake the functions of case management for chronic patients, improve the quality of life of patients, and meet the important task of community and family nursing needs.

Objective:To investigate the effect of the number of positive preoperative serological tumor markers on the surgical approach and prognosis of patients with intrahepatic cholangiocarcinoma.Methods:This is a retrospective case-series study. Data from 548 patients with intrahepatic cholangiocarcinoma after radical resection from October 2010 to April 2019 were retrospectively collected in 10 hospitals of China. There were 277 males and 271 females with an age of (57.8±10.2)years(range:23 to 84 years). Four hundred and twenty-six patients(77.7%) had at least one positive preoperative serum tumor marker. The data collection included the results of 4 preoperative serological tumor markers,other preoperative indicators(5 prodromal symptoms, 6 medical history,8 preoperative serological indicators,5 preoperative imaging indicators,and 14 preoperative pathological examination indicators),baseline data (gender and age),surgical methods,and prognostic follow-up data. Four preoperative results of serologic tumor marker and surgical procedure were converted into categorical variables. The number of positive preoperative serum tumor markers was used as the treatment variable,the surgical method was used as the mediating variable,and the survival time was used as the outcome variable. Univariate and multivariate analysis were used to screen for other preoperative indicators which were independent factors that influenced the surgical procedure and the prognosis of patients as covariates to analyze the mediating effect.Results:Of the 548 patients included in the study, 176 patients (32.1%) underwent partial hepatectomy,151 patients(27.5%) underwent hemihepatectomy, and 221 patients(40.3%) underwent partial hepatectomy or hemihepatectomy combined with other treatments. The results of the univariate and multivariate analysis showed that the number of positive serum tumor markers,intrahepatic bile duct dilatation,portal vein invasion,pathological differentiation,pathological type,vascular invasion,T stage,N stage and maximum tumor diameter were independent factors influencing the surgical procedure(all P<0.05). Intrahepatic bile duct dilatation,pathological differentiation and T stage were independent prognostic factors for patients with intrahepatic cholangiocarcinoma(all P<0.05). Intrahepatic bile duct dilatation,differentiation and T stage were included as covariates in the mediation effect model. The results showed that the number of positive serum tumor markers before surgery had a negative predictive effect on the survival time of patients with intrahepatic cholangiocarcinoma ( β=-0.092, P=0.039),and had a positive predictive effect on the surgical method ( β=0.244, P<0.01). The number of positive serum tumor markers had a negative predictive effect on the survival time of patients with intrahepatic cholangiocarcinoma ( β=-0.151, P=0.002). Direct and indirect effects accounted for 71.3% and 28.7% of total effects,respectively. Conclusions:The higher the positive number of preoperative tumor markers,the worse the prognosis of patients with intrahepatic cholangiocarcinoma. The number of positive cells not only directly affects the prognosis of patients,but also indirectly affects the prognosis of patients by affecting the surgical method.
