In this work, starting from 4-hydroxycoumarin, three series of 22 coumarin derivatives, among which 8 have not been reported in the literature, were synthesized and their in vitro anti-inflammatory activities and mechanisms of action were preliminarily investigated using mouse macrophage model. The results showed that most of the derivatives could significantly inhibit the production of pro-inflammatory factor NO, with compounds 2e, 2f, 2g, 2h, 2i, 2j, 4e, and 4f showing better anti-inflammatory activity than the positive control drug dexamethasone. Further experiments showed that compounds 2h and 4f significantly inhibited the production of pro-inflammatory factors IL-6, TNF-α and IL-1β in RAW264.7 macrophages, and could, therefore, be used as lead compounds for further studies.

Objective To investigate the expression of serum Elabela and leucine-rich-alpha-2-glycoprotein-1(LRG1)in ulcerative colitis(UC)patients and their correlation with disease activity index(DAI).Methods A total of 98 patients with UC admitted to Yuncheng Central Hospital from January to December 2022 were selected as the UC group,including 62 patients in active stage and 36 patients in remission stage.According to the severity of the disease,these patients were divided into mild group(n=26),moderate group(n=43)and severe group(n=29).In addition,these patients were grouped into gradeⅠ group(n=25),grade Ⅱ group(n=40)and grade Ⅲ group(n=33)based on the endoscopic activity index(EAI).According to the mucosal healing condition under endoscopy,these patients were divided into the healed group(n=65)and the unhealed group(n=33).Another 51 patients with colonic polyps were selected as control group 1,and 50 healthy individuals were selected as control group 2.Serum Elabela and LRG1 levels were detected by enzyme-linked immunosorbent assay(ELISA).Pearson method was used to analyze the correlation between serum Elabela,LRG1 levels and DAI in UC patients.Receiver operating characteristic(ROC)curve was applied to analyze the predictive value of serum Elabela and LRG1 for endoscopic mucosal healing.Results The levels of Elabela(4.77±1.36 ng/ml)and LRG1(352.12±39.45 ng/ml)in UC group were higher than those in control group 1(2.51±0.53 ng/ml,121.02±21.06 ng/ml)and control group 2(2.35±0.42 ng/ml,120.35±23.49 ng/ml),and the differences were statistically significant(t= 11.410～39.000,all P＜0.05).The levels of Elabela(5.26±0.54 ng/ml)and LRG1(370.42±12.49 ng/ml)in the active group were higher than those in the remission group(3.93±0.42 ng/ml,320.60±8.47 ng/ml),and the differences were statistically significant(t=12.705,21.242,all P＜0.05).The levels of Elabela(5.89±0.20 ng/ml)and LRG1(369.92±16.59 ng/ml)in the severe group were higher than those in the moderate groups(4.51±0.67 ng/ml,356.12±18.75 ng/ml)and mild groups(3.95±0.21 ng/ml,325.65±10.14 ng/ml),and the differences were statistically significant(t=3.205～35.077,all P＜0.05).The levels of Elabela(5.80±0.18 ng/ml)and LRG1(369.16±13.47 ng/ml)in grade Ⅲ group were higher than those in grade Ⅱ group(4.49±0.35 ng/ml,355.46±16.34 ng/ml)and grade Ⅰgroup(3.86±0.16 ng/ml,324.15±8.71 ng/ml),and the differences were statistically significant(t= 3.854～48.725,all P＜0.05).The levels of Elabela(5.12±0.42 ng/ml)and LRG1(367.12±14.27 ng/ml)in unhealed group were higher than those in healed group(4.08±0.37 ng/ml,322.57±10.35 ng/ml),and the differences were statistically significant(t=12.043,15.917,all P＜0.05).The serum levels of Elabela and LRG1 in UC patients were positively correlated with EAI and ESR(r=0.602,0.298;0.576,0.302,all P＜0.05),but negatively correlated with hemoglobin level(r=-0.351,-0.334,all P＜0.05).The area under the curve predicted by the combination of serum Elabela and LRG1 for endoscopic mucosal healing was 0.926(95%CI:0.880～0.958),was higher than the 0.803(95%CI:0.741～0.856)and 0.783(95%CI:0.720～0.838)predicted by Elabela and LRG1 alone,and the difference was statistically significant(Z=4.101,4.228,all P＜0.05).Conclusion The serum levels of Elabela and LRG1 in UC patients increased,and they were related to the increase of DAI and worsening of the condition.Testing serum Elabela and LRG1 can provide a reference for evaluating mucosal healing under UC endoscopy.

Objective:To observe the effect of Xuebijing injection on sepsis combined with acute gastrointestinal injury (AGI), and analyze the risk factors of sepsis combined with AGI.Methods:A retrospective cohort study was conducted. Patients with non-gastrointestinal origin admitted to the department of intensive care medicine of the First Hospital of Qinhuangdao from May 1, 2021 to October 30, 2023 were enrolled. The baseline data, source of sepsis infection, vital signs, acute physiology and chronic health evaluationⅡ(APACHEⅡ), sequential organ failure assessment (SOFA), laboratory tests, comorbidities, interventions during treatment, and the 28-day prognosis were collected. The patients were divided into Xuebijing group and non-Xuebijing group according to whether Xuebijing injection was used or not. According to whether AGI was merged or not, patients were divided into merged AGI group and non-merged AGI group. The main observational indexes were the difference in the incidence of AGI between the Xuebijing group and non-Xuebijing group and the difference in the magnitude of the decline in procalcitonin (PCT), C-reactive protein (CRP), and white blood cell count (WBC) at 7 days after admission, and the difference in the 28-day morbidity and mortality. Risk factors for AGI in septic patients were explored by univariate analysis, and statistically significant indicators were screened and included in binary Logistic regression analysis to determine independent risk factors.Results:A total of 129 patients with sepsis of non-gastrointestinal origin were enrolled, including 57 patients in the Xuebijing group and 72 patients in the non-Xuebijing group. Among 129 patients, 80 patients in the merged AGI group and 49 patients in the non-merged AGI group. There were no statistically significant differences between Xuebijing group and non-Xuebijing group in gender, age, body mass index (BMI), underlying disease, source of infection, vital sign, APACHEⅡscore, SOFA score, and clinical intervention, and there were no statistically significant differences in laboratory tests except for aspartate aminotransferase (AST) and blood urea nitrogen (BUN). The incidence of AGI was significantly lower in the Xuebijing group than that in the non-Xuebijing group [50.87% (29/57) vs. 70.83% (51/72), P < 0.05], and the 28-day mortality was slightly lower than that in the non-Xuebijing group [24.56% (14/57) vs. 30.56% (22/72), P > 0.05]. In the Xuebijing group, the decreases in CRP, PCT and WBC at 7 days after admission were greater than those in the non-Xuebijing group, with statistically significant differences in the decreases of CRP and PCT [CRP (mg/L): 47.12±67.34 vs. 7.76±111.03, PCT (μg/L): 14.08 (-1.22, 50.40) vs. 2.94 (-1.27, 14.80), all P < 0.05]. Univariate analysis showed that the use of acid suppressants, the use of analgesic sedation, the non-use of Xuebijing injections, pulmonary infections, and urinary tract infections were the risk factors for the development of AGI in patients with sepsis. Binary Logistic regression analysis further showed that the use of acid suppressants [odds ratio ( OR) = 2.450, 95% confidence interval (95% CI) was 1.021-5.883, P = 0.045], use of analgesic sedatives ( OR = 2.521, 95% CI was 1.074-5.918, P = 0.034), and urinary tract infection ( OR = 4.011, 95% CI was 1.085-14.831, P = 0.037) were independent risk factors for sepsis combined with AGI, in which the use of Xuebijing injection was a protective factor ( OR = 0.315, 95% CI was 0.137-0.726, P = 0.007). Conclusions:Xuebijing injection reduced the incidence of AGI in patients with non-gastrointestinal sepsis. PCT and CRP decreased more markedly than in patients who did not use Xuebijing injection. The use of acid-suppressing agents, analgesic and sedative agents, and urinary tract infections were independent risk factors for sepsis in combination with AGI, while the use of Xuebijing injection is a protective factor.

Objective To observe the application effect of magnetic resonance imaging technology in evaluating the brain structure and function of patients with type 2 diabetic painful neuropathy (PDN). Methods Forty patients with type 2 diabetes mellitus hospitalized in our hospital were selected as the study objects, and were divided into diabetes mellitus (DM) group (n=12), peripheral neuropathy (DPN) group (n=14) and PDN group (n=14). General clinical biochemical indexes of three groups were analyzed. The structural brain and function of brain area in three groups were compared. Results Age, duration of diabetes, systolic blood pressure, diastolic blood pressure, fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), free fatty acid (FFA), albumin (ALB), creatinine (Cr), uric acid (UA), estimated glomerular filtration rate (eGFR), cystatin C (Cys-C), total cholesterol (TC), triglyceride (TG) of the three groups were compared, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triiodothyronine (T3), thyroxine (T4), thyroid stimulating hormone (TSH), thyroglobulin antibody (TGAb), thyroid peroxidase antibody (TPO-Ab) and serum calcium (Ca) in the three groups showed no significant differences (P > 0.05). Compared with the DM group, the gray matter volume (GMV) in the DPN group was significantly decreased (P < 0.05). Compared with the DM group, amplitude of low frequency fluctuation (ALFF) and fractional amplitude of low frequency fluctuation (fALFF) of left medial superiorfrontal gyrus in the PDN group were significantly decreased (P < 0.05). Conclusion Abnormal GMV in the left angular gyrus in DPN patients may be associated with a higher risk of concomitant cognitive impairment. The decrease of ALFF in the right cerebellar vermis and fALFF in the left medial superior frontal gyrus in PDN patients may be related to the pathogenesis of pain.

Objective:To investigate the efficacy of hemodiafiltration combined with hemoperfusion in the treatment of secondary hyperparathyroidism (SHPT) in patients undergoing maintenance hemodialysis (MHD).Methods:A total of 40 patients with SHPT undergoing MHD who received treatment at the Blood Purification Center of The First Affiliated Hospital of Anhui University of Science and Technology from February 2021 to March 2023 were included in this prospective cohort study. They were randomly divided into a control group and an observation group ( n = 20/group).The control group received a single high flux hemodialysis, while the observation group used a combination of hemodialysis filtration and hemoperfusion for 3 months. In both groups, the changes in hemoglobin, blood urea nitrogen, serum creatinine, serum calcium, serum phosphorus,and parathyroid hormone levels were compared before and after dialysis. Results:After dialysis, the hemoglobin level in the observation group was (119.45 ± 5.27) g/L, which was significantly higher than (106.30 ± 6.52) g/L in the control group ( t = -7.02, P < 0.001). The serum phosphorus level in the observation group was (1.18 ± 0.17) mmol/L, which was significantly lower than (1.52 ± 0.22) mmol/L in the control group ( t = 5.49, P < 0.001). The parathyroid hormone level in the observation group was (122.14 ± 40.57) ng/L, which was significantly lower than (168.78 ± 78.27) ng/L in the control group ( t = 2.39, P = 0.023). Conclusion:Hemodiafiltration combined with hemoperfusion can reduce clinical symptoms, increase hemoglobin level, and reduce phosphorus and parathyroid hormone levels in patients with SHPT undergoing MHD, which deserves clinical promotion.

Objective To observe the clinical efficacy of Jiangshabanxia nano-paste on nausea and vomiting in end-stage patients and its effect on the quality-of-life (QOL) in cancer patients. Methods 120 end-stage patients with nausea and vomiting symptoms above grade III were randomly divided into observation group and control group. They were treated with Jiangshabanxia nano-paste and placebo paste respectively. The paste patch was changed every 24 hours and used continuously for 7 days. The nausea and vomiting symptom score, the quality-of-life measurement score and KPS score of cancer patients in the two groups were observed to evaluate the curative effect. Results After 7 days of treatment, the symptom scores of nausea and vomiting in the observation group decreased significantly, the KPS score of the observation group increased, and the effective rate was higher than that in the control group. The score of QOL measurement showed that after treatment, the score of main symptom areas and other symptom areas (except external dyspnea, diarrhea and economic difficulties) in the observation group decreased, and the score of overall health area increased. After treatment, the score of main symptom areas and other symptom areas (except external dyspnea, diarrhea and economic difficulties) in the observation group was lower than that in the control group, and the scores of overall health area in the observation group were higher than those in the control group. Conclusion Jiangshabanxia nano-paste has a good clinical efficacy nausea and vomiting in end-stage patients, it also can improve the quality of life end-stage cancer patients.
