Rheumatoid arthritis (RA) is an autoimmune disease with a complex etiology. Monocyte-derived macrophages (MDMs) infiltration are associated with RA severity. We have reported the deletion of G-protein-coupled receptor kinase 2 (GRK2) reprograms macrophages toward an anti-inflammatory phenotype by recovering G-protein-coupled receptor signaling. However, as more GRK2-interacting proteins were discovered, the GRK2 interactome mechanisms in RA have been understudied. Thus, in the collagen-induced arthritis mouse model, we performed genetic GRK2 deletion using GRK2f/fLyz2-Cre+/- mice. Synovial inflammation and M1 polarization were improved in GRK2f/fLyz2-Cre+/- mice. Supporting experiments with RNA-seq and dual-luciferase reporter assays identified peroxisome proliferator-activated receptor γ (PPARγ) as a new GRK2-interacting protein. We further confirmed that fms-related tyrosine kinase 1 (Flt-1), which promoted macrophage migration to induce angiogenesis, was inhibited by GRK2-PPARγ signaling. Mechanistically, excess GRK2 membrane recruitment in CIA MDMs reduced the activation of PPARγ ligand-binding domain and enhanced Flt-1 transcription. Furthermore, the treatment of mice with GRK2 activity inhibitor resulted in significantly diminished CIA pathology, Flt-1+ macrophages induced-synovial inflammation, and angiogenesis. Altogether, we anticipate to facilitate the elucidation of previously unappreciated details of GRK2-specific intracellular signaling. Targeting GRK2 activity is a viable strategy to inhibit MDMs infiltration, affording a distinct way to control joint inflammation and angiogenesis of RA.

Objective To explore the prevalence rate and related factors of urban and rural residents with hyperuricemia (HUA). Methods A total of 360 subjects in physical examination department of Sanliusan Hospital from January 2020 to January 2023 were selected and divided into urban residents and rural residents according to their permanent residence addresses, and the demographic information, living habits and underlying diseases were collected. Fasting blood glucose (FBG), serum uric acid (SUA), body mass index (BMI) and triglyceride (TG) were measured. The risk factors of HUA were analyzed by logistics regression analysis. Results The incidence rates of HUA in urban and rural residents were 12.18% and 12.88%. There were statistically significant differences in education level, occupation, BMI, sleep time, alcohol drinking, FBG and TG between urban and rural residents (all P<0.05). Logistics regression analysis showed that male, BMI>24 kg/m2, alcohol drinking and chronic kidney disease were independent risk factors for HUA occurrence among urban residents (all P<0.05). Chronic kidney disease, FBG≥7.0 mmol/L and TG≥2.3 mmol/L were independent risk factors for hyperuricemia occurrence among rural residents (all P<0.05). Conclusion Rural residents should strengthen health education and blood glucose and lipid control, and urban residents should pay more attention to reasonable exercise, control alcohol consumption and reduce HUA occurrence.

Objective:
To compare the efficacy and safety of combining diosmin with Jiuhua hemorrhoid suppository versus diosmin alone for the treatment of hemorrhoid hemorrhage.
Methods:
The Jiuhua hemorrhoid suppository study was conducted in 10 medical centers across China from April 1, 2019 to June 30, 2020. Patients with hemorrhoid bleeding were randomized in a ratio of 1 : 1 to either receive Jiuhua hemorrhoid suppository and diosmin tablets (the study group) or diosmin tablets alone (the control group). The suppository was used once a day after defecation or at bedtime after rinsing the anus with warm water. Diosmin tablets were administered only once a day (0.9 g). The primary endpoint of the study was the assessment of hemorrhoid bleeding relief 7 ± 2 days after treatment, classified as “very effective” “effective” and “ineffective”. The secondary endpoint included the evaluation of pain alleviation using the visual analogue scale (VAS, with scores ranging from 0 to 10) and edema (with scores ranging from 0 to 3). The safety of the two treatment regimens was evaluated 14 ±
2 days after drug administration.
Results:
The full analysis set (FAS) comprised 107 participants in the study group and 111 in the control group, while the per-protocol set (PPS) included 106 participants in the study group and 111 in the control group. In terms of hemorrhoid bleeding, the proportion of very effective and effective cases in the study group were significantly higher than that in the control group [106 (99.06%) vs. 91 (81.98%), P < 0.0001] in the FAS, and the PPS results [105 (99.06%) vs. 91 (81.98%), P < 0.0001] were comparable to the FAS results. The pain VAS scores at day 7 after treatment were comparable between the two groups (0.80 ± 1.17 vs. 0.80 ± 1.20, P = 0.2177). The majority of the participants in both groups had an edema score of 0 at day 7 after treatment [96 (89.72%) vs. 99 (91.67%), P = 0.370 5]. Adverse events (AEs) occurred in 9 patients (8.4%) in the study group and 3 patients (2.7%) in the control group. In addition, 5 AEs in the study group and 1 AE in the control group were possibly in association with the study drug.
Conclusion
Compared with the administration of diosmin oral tablets alone, the addition of Jiuhua hemorrhoid suppository to the tablets demonstrates enhanced efficacy in addressing hemorrhoid bleeding, with satisfactory patient adherence and acceptable safety.

Objective:
To establish an inducible macrophage-specific knockout G protein-coupled receptor kinase 2 ( GRK2) gene ( GRK2flox / flox Lyz2-CreERT + ) mice model.
Methods:
GRK2flox / flox Lyz2-CreERT + mice were constructed based on Cre / LoxP system.The genotypes of GRK2flox / floxLyz2-CreERT + mice were identified by PCR amplification and agarose gel electrophoresis.After the mice were sacrificed by carbon dioxide method,the expression of GRK2 in bone marrow-derived macrophages ( BMDMs) and peritoneal macrophages ( PMs) was detected by Western blot.Immunofluorescence was used to detect GRK2 expression in mouse brain,heart and spleen macrophages.The M1 / M2 ratio in PMs induced by prostaglandin E2 (PGE2) was analyzed by flow cytometry.
Results:
The results of genotype identification showed that the mice with a band at 355 bp in the length of the flox amplification product and a band at 355 bp in the length of the Cre amplification product were GRK2flox / floxLyz2-CreERT + mice.Western blot results showed that GRK2 expression in BMDMs and PMs of GRK2flox / floxLyz2-CreERT + mice decreased compared with GRK2flox / flox mice(P<0. 01) .Immunofluorescence results showed that GRK2 expression decreased in the brain,heart and spleen of GRK2flox / floxLyz2-CreERT + mice compared with GRK2flox / flox mice (P < 0. 01) .Flow cytometry showed that compared with GRK2flox / flox mice,there was no significant difference in the proportion of CD86 / CD206 in the PMs of GRK2flox / floxLyz2-CreERT + mice.Under PGE2 ( 10 μmol / L) stimulation, the proportion of CD86 / CD206 in GRK2flox / floxLyz2-CreERT + mice PMs increased (P <0. 01) .The proportion of CD86 / CD206 in the PMs of GRK2flox / flox mice was higher than that of GRK2flox / floxLyz2-CreERT + mice(P<0. 01) .
Conclusion
In this study,GRK2flox / floxLyz2-CreERT + mice model was successfully constructed,and the mice promoted PGE2-induced polarization of PMs to M2-type macrophages compared with control mice.

Objective To evaluate the short-term therapeutic effect of extended adventitial inversion with graft eversion anastomosis technique in the root treatment of acute type A aortic dissection (ATAAD). Methods From November 2019 to July 2020, 28 patients with ATAAD were treated by extended adventitial inversion with graft eversion anastomosis technique in the Department of Cardiovascular Surgery, Dalian Municipal Central Hospital, including 19 males and 9 females, aged 60.11±11.11 years. The intima of the ascending aorta was trimed to 5 mm above the sinotubular junction. The adventitia of the ascending aorta was longitudinally cut to the reserved intima margin along the junction of the three aortic valves. The extended adventitial inversion was sutured continuously, no coronary sinus was sutured over the aortic annulus, and the left and right coronary sinus was sutured above the coronary ostium. The anastomotic graft was everted and inserted into the aortic lumen, and the everted graft was continuously sutured at the level of sinotubular junction which was 5 mm away from the edge of graft. Results There was no intraoperative death, intractable root hemorrhage, residual root false lumen, root dilatation, anastomotic hematoma or other complications. There was no recurrence of the pain in the back of all patients, and the results of the CT angiography were not significantly changed. In 22 patients with no regurgitation, only 1 (4.55%) patient had a mild regurgitation. In 6 patients with mild aortic regurgitation, the disappearance rate of regurgitation was 50.0% (3/6). Conclusion The treatment of extended adventitial inversion with graft eversion anastomosis technique in the root treatment of aortic dissection eliminates the residual dissection at the root. The anastomotic hemorrhage is prevented, the root structure of aortic dissection is reconstructed and strengthened, the root function is restored, and the possible expansion of the root is prevented. The short-term results are satisfactory.

Objective:To investigate the expression of forkhead box protein O3(FOXO3) in pancreatic cancer and its effect on the motility and proliferation of pancreatic cancer cells.Methods:The FOXO3 expression in pancreatic cancer and adjacent tissues was retrieved from LinkedOmics database. Western blotting and real-time quantitative polymerase chain reaction were used to detect FOXO3 expression in pancreatic cancer cells and human pancreatic stellate cells. PANC-1 and MIAPaCa-2 pancreatic cancer cells with low FOXO3 expression were selected to transfect FOXO3 overexpression plasmid and negative control plasmid, respectively. The motility and proliferation ability of pancreatic cancer cells were detected by colony formation assay, cell scratch assay, Transwell assay and flow cytometry.Results:In the LinkedOmics database, the relative expression of FOXO3 protein in the cancer tissues of 64 patients with pancreatic cancer was significantly lower than that in the adjacent tissues ( t=8.36, P<0.001). The number of clones in PANC-1 cell line was (30.0±6.6) after overexpressed FOXO3, which was lower than that in negative control cells (92.7±6.7), and the difference was statistically significant ( t=11.54, P<0.001). After overexpressed FOXO3 in PANC-1 and MIAPaCa-2 cell lines, the scratch repair rate was significantly decreased compared with the control group. In Transwell experiment, the number of cells in FOXO3 overexpressed group in PANC-1 cell lines was (21.0±6.6), which was lower than that of negative control groups (55.7±8.5), and the difference was statistically significant ( t=5.59, P=0.005). The results of MIAPaCa-2 cell line were consistent with that of PANC-1 cell line. After overexpressing of FOXO3 in PANC-1 and MIAPaCa-2 cell lines, the proportion of cells in the G0/G1 phase decreased, while the proportion in the S phase increased. Conclusion:The expression of FOXO3 was decreased in pancreatic cancer. Overexpression of FOXO3 could significantly inhibit the proliferation, migration and invasion of pancreatic cancer cells and induce cell cycle arrest, which is a potential target for the treatment of pancreatic cancer.

Objective:To explore the current situation of rumination and hope level in stroke patients and to analyze the effect of rumination on their hope level, so as to provide a basis for clinical intervention.Methods:Using the convenient sampling method, stroke patients admitted to Lanling County People's Hospital from March to June 2021 were selected as the research objects. General data questionnaire, Chinese Version of Event Related Rumination Inventory (C-ERRI) and Herth Hope Scale were used to investigate the patients. Multiple linear regression analysis was used to analyze the influencing factors. A total of 100 questionnaires were distributed in this study, and 92 valid questionnaires were recovered, with an effective recovery rate of 92.0%.Results:The total score of C-ERRI in 92 stroke patients was (29.40±7.89) and the total score of Herth Hope Scale was (32.97±6.52) . Pearson correlation analysis showed that purposeful rumination in stroke patients was positively correlated with the total score and each dimension scores of Herth Hope Scale ( P<0.05) . The results of multiple linear regression analysis showed that gender, education level, economic income level, Barthel index and purposeful rumination were influencing factors of the hope level of stroke patients ( P<0.05) . Conclusions:The hope level of stroke patients is not high, and more attention should be paid to stroke patients who are female, have a lower education level, a lower level of economic income and have poor activities of daily living. And certain measures should be taken to improve the level of purposeful rumination of patients, thereby raising its hope level.
