Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.

Objective:To evaluate the efficacy and safety of oliceridine for treatment of moderate to severe pain after surgery with general anesthesia in patients.Methods:The patients with moderate to severe pain (numeric pain rating scale ≥4) after abdominal surgery with general anesthesia from 14 hospitals between July 6, 2021 and November 9, 2021 were included in this study. The patients were assigned to either experiment group or control group using a random number table method. Experiment group received oliceridine, while control group received morphine, and both groups were treated with a loading dose plus patient-controlled analgesia and supplemental doses for 24 h. The primary efficacy endpoint was the drug response rate within 24 h after giving the loading dose. Secondary efficacy endpoints included early (within 1 h after giving the loading dose) drug response rates and use of rescue medication. Safety endpoints encompassed the development of respiratory depression and other adverse reactions during treatment.Results:After randomization, both the full analysis set and safety analysis set comprised 180 cases, with 92 in experiment group and 88 in control group. The per-protocol set included 170 cases, with 86 in experiment group and 84 in control group. There were no statistically significant differences between the two groups in 24-h drug response rates, rescue analgesia rates, respiratory depression, and incidence of other adverse reactions ( P>0.05). The analysis of full analysis set showed that the experiment group had a higher drug response rate at 5-30 min after giving the loading dose compared to control group ( P<0.05). The per-protocol set analysis indicated that experiment group had a higher drug response rate at 5-15 min after giving the loading dose than control group ( P<0.05). Conclusions:When used for treatment of moderate to severe pain after surgery with general anesthesia in patients, oliceridine provides comparable analgesic efficacy to morphine, with a faster onset.

Objective To explore the mechanism of hydroxyl safflower flavin A(HSYA)in the treatment of sepsis-induced liver injury by using metabolomics and network pharmacology.Methods A total of 50 male C57BL/6 mice were randomly divided into sham-operation group(10 mice),sepsis group(20 mice)and HSYA group(20 mice).Cecal ligation and puncture was conducted to establish the sepsis-induced liver injury mouse model.The mice in HSYA group were subcutaneously injected with HSYA after 2 hours of modeling.The content of serum inflammatory factors and liver function were detected,and the pathological changes of liver tissue were observed with HE staining,UPLC-Q-TOF-MS metabolomics was used to analyze liver tissue,screening for differential metabolites using multivariate statistical methods,network pharmacology was used to predict potential targets for HSYA treatment of sepsis-induced liver injury,and conduct GO and KEGG pathway enrichment analysis on potential targets,Metabo Analyst 5.0 database was used to match differential metabolites and potential targets between the model group and HSYA group,a targets metabolite-metabolism pathway network was constructed.AutoDock Vina software was used to perform molecular docking between HSYA and core genes,and finally RT-qPCR was used to verify the expression of core genes.Results HSYA can reduce the contents of IL-6,IL-1β and TNF-α in serum,restore liver function,and alleviate the morphological alternation in liver induced by sepsis.A total of 26 differential metabolites identified by metabolomics were screened out,including flufenamic acid,cryptolepine,opthalmic acid,fenpropathrin etc.,which were mainly involved in 5 metabolic pathways such as biosynthesis of unsaturated fatty acids and alpha-linolenic acid metabolism.Network pharmacology identified 81 potential targets,2 735 items enriched in GO and 124 signaling pathways enriched in KEGG;a total of 5 differential metabolites were matched for joint analysis,corresponding to 14 targets including IL1B,STAT3,PTGS2,TP53,etc.,involved in the regulation of metabolic disorders in sepsis-induced liver injury by HSYA.Molecular docking results showed that HSYA had good binding activity to IL1B,STAT3,PTGS2 and TP53 targets.RT-qPCR results showed that HSYA could inhibit the expressions of IL1B,STAT3 and PTGS2 in liver tissue.Conclusions HSYA may inhibit the release of inflammatory cytokines,maintain metabolic homeostasis,and alleviate sepsis-induced liver injury through modulating the expressions of IL1B,STAT3,and PTGS2.

Objective:To analyze the clinical characteristics of functional esophagogastric junction outflow obstruction (EGJOO) and to improve the knowledge of functional EGJOO.Methods:From January 2015 to December 2019, at the Gastrointestinal Motility Center of The First Affiliated Hospital with Nanjing Medical University, 91 patients who underwent high resolution esophageal manometry (HREM) and met the EGJOO criteria of Chicago Classification for esophageal motility disorders, 3rd edition and excluded organic diseases by examination such as gastroscopy or upper gastrointestinal radiography were collected. The clinical manifestations, treatment methods, effect and clinical outcome of patients with functional EGJOO, the HREM parameters of patients with different clinical manifestations as well as symptoms and HREM parameters of patients with different treatments were analyzed. Least significant difference test or Tamhanes T2 test, Mann-Whitney U or Wilcoxon test, chi-square test or Fisher exact test were used for statistical analysis. Results:The most common symptom of 91 functional EGJOO patients was dysphagia (34/91, 37.4%). The lower esophageal sphincter pressure (LESP) and the intrabolus pressure during relaxation of the lower esophageal sphincter (IBP LESR) of patients with dysphagia were both higher than those of patients without dysphagia (30.95 mmHg (26.27 mmHg, 39.37 mmHg) (1 mmHg=0.133 kPa) vs. 27.35 mmHg (24.60 mmHg, 34.87 mmHg); (8.25±4.64) mmHg vs. (5.69±4.65) mmHg), and the differences were statistically significant ( Z=2.076, t=2.539; P=0.038, 0.013). Thirty patients (33.0%) had no special treatment, 52 patients (57.1%) were treated with medication, and nine patients (10.0%) underwent peroral endoscopic myotomy (POEM). The incidence of dysphagia before treatment and maximum intrabolus pressure of patients who underwent POEM were both higher than those of patients without special treatment and medication treatment (8/9 vs 43.3%, 13/30 and 25.0%, 13/52; 21.80 mmHg (15.45 mmHg, 28.95 mmHg) vs. 12.20 mmHg (10.00 mmHg, 18.10 mmHg) and 13.70 mmHg (11.07 mmHg, 17.82 mmHg)), and the differences were statistically significant (Fisher exact test, Fisher exact test; Z=2.814, 2.390; P=0.023, P<0.01, P=0.005, 0.017). The incidences of delayed esophageal emptying or esophageal dilation of patients who underwent POEM, without special treatment and with medication treatment was 6/9, 5/14 and 3/18, respectively, and the differences were statistically significant among three groups (Fisher exact test, P=0.039). Among them, the incidence of delayed esophageal emptying or esophageal dilation of patients received POEM before treatment was higher than that of patients with medication treatment (Fisher exact test, P=0.026). The symptoms of 24.2% (22/91) was spontaneously relieved, and two patients (2.2%) developed type Ⅱ achalasia during follow-up. Conclusions:The main manifestation of patients with functional EGJOO is dysphagia. Patients with significantly increased LESP and IBP LESP are more likely to have dysphagia. Patients with obvious signs of esophageal gastric junction obstruction are more inclined to choose POEM treatment. Some patients with functional EGJOO can relieve themselves, and a few patients can develop achalasia.

Objective To evaluate the safety and efficacy of endoscopic ultrasound (EUS) guided ethanol ablation of benign insulinoma and compare its' advantages and disadvantages with surgical treatment. Methods From April 2011 to February 2016, clinical data of 38 patients with benign insulinoma treated by EUS-guided ethanol ablation or surgical treatment were retrospectively analyzed. Results 97.4% (37/38) patients had a typical clinical manifestation of Whipple's triad, and the I/G ratio of 82.9% patients (29/35) was more than 0.3 with their onset of hypoglycemia. The positive preoperative etiologic diagnosis rates of transabdominal ultrasonography, CT, MRI, PET/CT and EUS were 50.0%, 67.6%, 66.7%, 75.0%, 89.7% respectively. In the current study, 18 patients underwent EUS-guided ethanol ablation (EUS-FNI group) and 20 patients received surgicaltreatment (surgical group). Compared with the surgical group, the operation time, intraoperative hemorrhage volume, postoperative complications, length of stay and hospitalization costs were significantly reduced in the EUS-FNI group (P < 0.05). No treatment-related complications was observed in EUS-FNI group, while 40.0% (8/20) patients in surgical group had complications. During the follow-up period, all these patients maintained stable blood glucose without taking medication, and there's no recurrence of insulinoma in EUS-FNI group after the last treatment with alcohol injection; In surgical group, only 90.0% (18/20) patients had no recurrence, episode of hypoglycemia was less after the operation in 10.0% (2/20) patients. Conclusion EUS-guided ethanol ablation of benign insulinoma is safe and effective, compared with traditional surgical treatment, EUS-guided ethanol ablation is minimally invasive, costs less, recovers fast after treatment and has fewer complications.

AIM: To investigate the effect of nucleolin on diabetic cardiomyopathy in mice.METHODS: A type II diabetic cardiomyopathy mouse model was prepared using a cardiac-specific nucleolin-overexpressing transgenic mice.The mice were divided into wild-type mouse control group, nucleolin transgenic mouse control group, wild-type mouse diabetes group and nucleolin transgenic mouse diabetes group.Wheat germ agglutinin (WGA) fluorescent dye, Masson staining and PowerLab system detection were used to further clarify the role of nucleolin on cardiac hypertrophy, fibrosis and cardiac function in type II diabetic cardiomyopathy mice.RESULTS: Compared with wild-type mouse control group, no significant increase in blood glucose level was found, while genetical myocardial cell hypertrophy was significantly attenuated in nucleolin transgenic mouse diabetes group.The collagen fibers were also significantly reduced, and hemodynamic indexes ± dp/dtmax, left ventricular end-diastolic pressure, left ventricular systolic pressure and heart rate were also improved.The above differences were statistically significant.CONCLUSION: Nucleolin may reduce the occurrence of myocardial hypertrophy and fibrosis, thus improving the cardiac function of diabetic cardiomyopathy mice.
