    Objective To design and validate a mouse gambling experimental paradigm so as to provide an objective measure to evaluate impulsivity in decision-making associated with neuropsychiatric diseases. Methods The experimental paradigm was validated using C57/BL6J mice. The experimental paradigm was structured into six sessions, each with specific criteria and assessment standards. The first session involved a food restriction phase, maintaining the mices weight at 85% of the initial weight. The second session focused on apparatus adaptation, where mice obtained food solely within the operant chamber. The third session was dedicated to touchscreen training, subdivided into three tasks, i.e., initial touchscreen task, two-choice touchscreen task, and single-choice touchscreen task, which trained mice to touch white squares on the screen to obtain food. The fourth session was the basic touchscreen task, in which the mice continued to touch white squares for food access, but intervals between tasks were introduced without varying the levels of reward or risk. The fifth session, the forced-choice task, required mice to touch white squares to get food, teaching them the associations among different squares and their corresponding rewards and risks. The sixth session introduced a free-choice task, allowing mice to freely choose between high-risk or low-risk squares for variable rewards, thereby evaluating their impulsivity in decision-making. Results The number of completed trials in the touchscreen tasks exceeded 130 times per day. In the basic touchscreen task, the accuracy rate was above 80.00%, with a missing rate below 20.00%. The number of completed trials in the forced-choice task exceeded 80 times per day, with a consistent accuracy rate of 100.00%. In the free-choice task, the number of completed trials exceeded 60 times per day, with high-risk proportions ranging from 20.00% to 30.00%. Conclusion This paradigm outperforms alternative models by yielding higher accuracy in trained mice and avoids the use of punitive measures, providing a reward-dependent approach to studying impulsivity in decision-making. It holds significant theoretical and practical value in advancing our understanding of the neural mechanisms underlying neuropsychiatric diseases and in the development of new treatment strategies.

    Objective To investigate the expression of orphan nuclear receptor 4A1(NR4A1)in human umbilical vein endothelial cells(HUVECs)induced by hydrogen peroxide(H2O2)oxidative stress, and its effects and mechanism in cell apoptosis. Methods After HUVECs were treated with different concentrations and exposure times of H2O2, cell activity, apoptosis and protein expressions of Bcl-2, Bax and NR4A1 were detected with CCK-8, TUNEL and Western blotting, respectively. siRNA was transfected into HUVECs to obtain the knocked down NR4A1 cells(si-NR4A1)and control(si-NC). After H2O2 treatment, the levels of cell apoptosis, and the Bax/Bcl-2 ratio were detected. Lentivirus transfection was used to establish stably overexpressed NR4A1 HUVECs, which were treated with H2O2 and divided into empty vector control group(NC), NR4A1 overexpressed group(OV), NC+H2O2 group, and OV+H2O2 group. The cell apoptosis was determined with TUNEL, and the protein expressions of NR4A1, Bcl-2, Bax, total IκBα, and the nuclear/cytoplasmic localization of P65 protein in each group were determined with Western blotting. Results After the cells were treated with 200 μmol/L H2O2 for 6 hours, the vitality of HUVECs significantly decreased, the rate of apoptosis significantly increased, the Bax/Bcl-2 ratio increased(P<0.001), and the protein expression of NR4A1 increased. Compared with the si-NC group, the si-NR4A1 group had decreased Bax/Bcl-2 ratio and cell apoptosis after H2O2 treatment(P<0.001). Compared with the NC+H2O2 group, the OV+H2O2 group had significantly decreased cell apoptosis rate and Bax/Bcl-2 ratio(P<0.05). Compared with the NC+ H2O2 group, the OV+ H2O2 group had significantly decreased P65 protein expression in the nucleus(P<0.05), but significantly increased expression in the cytoplasm(P<0.001). Compared with the NC+ H2O2 group, the OV+ H2O2 group had significantly upregulated total IκBα expression(P<0.001). Conclusion H2O2 induces apoptosis in HUVECs; NR4A1 inhibits cell apoptosis by regulating the expression of IκBα and inhibiting the nuclear translocation of NF-κB in HUVECs.

    Objective To investigate the influence of GPR56 Stachel peptide(P19)on the browning of beige adipose tissue and its molecular mechanisms. Methods qPCR and Western blotting techniques were used to assess the expression levels of GPR56 in beige adipose tissue. ELISA assay was used to investigate the impact of 50 μmol/L P19 on the downstream IP3 level changes caused by activation of GPR56 Gq pathway in mouse beige adipose tissue. Subsequently, during the induction of browning differentiation in primary beige adipocytes, the expression levels of browning marker genes and thermogenic marker genes were evaluated using qPCR. A comprehensive analysis was performed to elucidate the effects of P19, YM-254890(YM), and Gpr56 gene silencing on the differentiation process. Results GPR56 was highly expressed in beige adipose tissue. P19 can increase the expression levels of browning marker genes(Tbx and Tmem26)and heat production marker genes(Ppargc1a, Cox7a1 and Cidea)with statistically significant differences(P<0.05). Moreover, when YM was added or Gpr56 expression was silenced, a reversal in the expression levels of these browning and thermogenic marker genes was observed. Conclusion P19 can promote the browning process of beige adipose tissue through the activation of the Gq pathway.

    Objective To study the secondary metabolites and biological activities of fungus Penicillium terrigenum RD 4-3 isolated from saline-alkali soil in the Yellow River Delta. Methods The secondary metabolites were isolated and purified using various chromatographic methods from culture broth, and the structures of the pure compounds were identified based on their physicochemical properties and spectral data. Cytotoxic activity and NO detection were performed to explore antineoplastic activity and anti-inflammatory activity. Results Fourteen pure compounds were isolated and identified from the extracts of Penicillium terrigenum RD 4-3, including sesquiterpenes 14-hydroxypetasol(1), 6-dehydropetasol(2), isopetasol(3), acremeremophilane G(4), phomenone(6), 7-hydroxypetasol(7), sporogen-AO1(9), petasol(10), JBIR-28(11), JBIR-27(12), 3-acetyl-13-deoxyphome(13)and penicilleremophilane A(14), and benzene derivatives 3-chloro-4-hydroxypheylacetamide(5)and phenols(8), among which 14-hydroxypetasol was a new compound. The activity results showed that phomenone(6)and sporogen-AO1(9)exhibited significant antitumor activities against non-small cell lung cancer cells A549 and H1299, with IC50 values below 10 μmol/L. At a concentration of 50 μmol/L, phomenone, petasol and JBIR-28 exhibited anti-inflammatory activity in the LPS-induced inflammation model. Preliminary structure-activity relationship revealed that the 6,7-epoxyl structure could significantly increase the antitumor and anti-inflammatory activities of the compounds. Conclusion The sesquiterpenes of the secondary metabolitesfrom fungus Penicillium terrigenum RD 4-3 from the Yellow River Delta exhibit great potential in the discovery of antitumor and anti-inflammatory lead compounds.

    Objective To investigate the early clinical efficacy of left internal thoracic artery(LITA)plus radial artery(RA)in total arterialized coronary artery bypass grafting(TA-CABG). Methods The clinical data of 105 patients who underwent total TA-CABG during Jan. 2020 and Jun. 2022 in the Department of Cardiovascular Surgery of Shandong Provincial Qianfoshan Hospital were retrospectively analyzed, including 59 who underwent off-pump coronary artery bypass grafting(OPCAB)and 46 who underwent on-pump coronary artery bypass grafting(ONCAB). Preoperative data, intraoperative graft acquisition and anastomosis methods, postoperative complications and management measures were included. Computed tomography angiography(CTA)was conducted in all patients 12 months after surgery to evaluate the graft patency rate and incidence of adverse cardiovascular events. Results The operation time of ONCAB group was longer than that of OPCAB group, while the postoperative hospital stay was shorter, with statistically significant difference(P=0.006). However, there were no statistically significant differences in the number of anastomosis, flow in grafts, postoperative mechanical ventilation time, 24 h postoperative drainage, arrhythmia, perioperative myocardial infarction, incision infection and forearm complications(P>0.05). No death or postoperative cerebrovascular events occurred in either groups. Conclusion LITA plus RA yields satisfactory early clinical outcomes in TA-CABG. ONCAB group needs shorter hospital stay than OPCAB group. Protection of radial nerve branch is important when RA is obtained. Intraoperative and postoperative antispasmodic therapy is essential.

    Objective To analyze the adverse reaction signals of nintedanib using the food and drug administration adverse event reporting system(FAERS)database. Methods Cases reported in the FAERS database from the July of 2014 to September of 2023 with nintedanib as suspected cause of adverse drug events were collected. After standardization of the WHO adverse drug reaction terminology, the reporting odds ratio method(ROR), proportional reporting ratio method(PRR)and multinomial gamma Posson distribution(MGPS)methods were used for adverse reaction signal detection. Results In total, 17,547 adverse reaction case reports listing nintedanib as the primary suspected drug were extracted from the FAERS database. Most patients were male(9,709 cases, 55.3%). The age mainly ranged from 65 to 85(8,856 cases, 50.5%). The majority of cases were reported from United States(10,209 cases, 58.2%), and the largest number of cases was reported in 2022(2,876 cases, 17.46%). In total, 24 cardiovascular adverse reaction signals were obtained through the ROR, PRR and MGPS methods, among which the RORs were highest for paroxysmal arrhythmia, aortic rupture, aortic valve calcification, heart valve surgery, and cardiac catheterization were ranked higher. The reported adverse reactions included hypertension(385 cases), elevated blood pressure(291 cases), myocardial infarction(182 cases), hypotension(175 cases), and atrial fibrillation(142 cases). The adverse reaction signals were consistent with the excavation signals, although adverse reactions such as aortic rupture, aortic valve calcification, and atrial fibrillation were not listed in the drug instructions. Conclusion Drug evaluation should be performed before the clinical use of nintedanib, especially for high-risk patients with cardiovascular diseases such as vascular disease, ischemic heart disease,and arrhythmia. Monitoring using electrocardiogram, electrolyte measurement, cardiac ultrasound, and other techniques should be strengthened, and clinicians should pay attention to adverse reactions beyond those listed in the instructions are included to ensure the safe use of this drug.

    Objective To compare the effects of different body mass index(BMI)on the cumulative birth rate(CLBR)in patients with normal ovarian response undergoing in vitro fertilization/intracytoplasmic sperm microinjection(IVF/ICSI). Methods A retrospective analysis of 3,227 oocyte retrieval cycles treated with IVF/ICSI was performed. Patients were divided into low BMI group(BMI<18.5, n=167), normal BMI group(18.5≤BMI<24.0, n=2,024), overweight group(24.0≤BMI<28.0, n=816), and obese group(BMI≥28.0, n=220). Clinical characteristics, laboratory indicators and pregnancy outcomes were compared among the groups. Results The total amount of gonadotrophin(Gn)elevated with increasing BMI in all four groups, with significant difference(P<0.001). There were no significant differences in the number of oocytes, number of high-quality embryos, 2PN fertilization rate, and 2PN cleavage rate among the four groups(P>0.05). The high-quality embryo rate and blastocyst formation rate in the obese group were lower than those in the normal BMI group(P=0.012, P<0.001)and overweight group(P=0.014, P<0.001). Oocyte utilization was significantly lower in the overweight and obese groups than in the normal BMI group(P=0.031, P=0.002). The miscarriage rate was higher in the overweight group than in the normal BMI group(P=0.013). CLBR was lower in the obese and overweight groups than in the normal BMI group(P=0.009, P=0.023). There were no significant differences in the clinical pregnancy rate and preterm labor rate among the four groups(P>0.05). Higher BMI was significantly associated with lower CLBR, and an adjusted OR(95%CI)was 0.953(0.948-0.958). Conclusion In patients with normal ovarian response undergoing assisted reproductive technology, overweight and obesity lead to increased total dosage of Gn, and the high-quality embryo rate, blastocyst formation rate, oocyte utilization rate and CLBR are significantly lower in obese patients, indicating that such patients should undergo aggressive weight loss before proceeding to assisted reproduction therapy.

    Objective To explore the diagnostic value of dynamic changes of monocyte/lymphocyte ratio(MLR)in the prognosis of acute-on-chronic hepatitis B liver failure(ACHBLF). Methods The study involved ACHBLF patients from January 2010 to July 2023 in the Department of Hepatology, Qilu Hospital of Shandong University. Smooth curve fitting and threshold effect analysis were used to evaluate the nonlinear relationship between MLR and 30-day mortality of ACHBLF patients. Logistic regression analysis and the Boruta algorithm were used to assess risk factors for 30-day mortality. The receiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of MLR and the bootstrap method was used for internal validation. Results In this study, 98 of the 243 individuals died within 30 days after hospitalization. MLR on the 8th day was identified as an independent risk factor for 30-day mortality of ACHBLF patients(OR=1.33, 95%CI:1.01-1.75, P=0.044), which was reported to be nonlinearly associated with 30-day mortality. Patients with MLR >1 on the 8th day showed a higher risk of mortality than those with MLR≤1(P<0.001). ROC curve showed that combination of MLR on the 8th day and the model for end-stage liver disease(MELD)score presented the area under the ROC of 0.775(95%CI: 0.69-0.86). Conclusion MLR>1 on the 8th day predicts poor 30-day prognosis in ACHBLF patients, and monitoring the dynamic changes of MLR is essential for the treatment of ACHBLF.

    Objective To determine the molecular etiology in a child with 21-hydroxylase deficiency using single molecular real-time sequencing(SMRT), and explore its clinical application for gene detection. Methods SMRT technology was applied to perform long-read sequencing on the candidate gene for congenital adrenal hyperplasia in the proband, and the results were compared to those obtained from multiplex ligation-dependent probe amplification(MLPA)and Sanger sequencing in the family. Results The SMRT results revealed three pathogenic variants in the probands CYP21A2 gene, including two tandemly arranged gene copies on one chromosome(one CYP21A2 copy with c.955C>T mutation and the other CYP21A2/CYP21A1P chimeric copy with a c.1069C>T mutation), and a deletion of the CYP21A2 gene on the other chromosome. These variants were consistent with the results obtained by MLPA+Sanger sequencing in the family, and the arrangement of the CYP21A2/CYP21A1P chimeric gene was clarified. Conclusion SMRT technology can identify gene copy number variations, structure variations, and chimeric genes, providing more valuable information for genetic diagnosis and carrier screening of 21-hydroxylase deficiency.

    Objective To evaluate the therapeutic effect of rapid maxillary expansion combined with anterior traction on maxillary transverse deficiency in patients with skeletal Class III malocclusion during the mixed dentition period using cone beam computed tomography(CBCT)technology. Methods A total of 19 mixed dentition patients(average age 8.47±0.70 years old )with skeletal Class Ⅲ malocclusion were selected. CBCT was taken before maxillary protraction combined with rapid maxillary expansion(T1)and 3 months after treatment(T2), respectively, to measure the inclination of the first maxillary molar, the crown width and alveolar width of the first maxillary premolar, the second primary molar and the first molar, the width of the maxillary basal bone, the height of the alveolar crest and the location of the second maxillary premolar germ in the alveolar bone. The differences in various measurement items before and after treatment were compared. Results The crown width of the first maxillary premolar increased by(2.37±3.47)mm(P=0.008), the median increase in crown width of the second primary molar was 3.37mm(P=0.009)and the crown width of the first molar increased by(2.60±2.53)mm(P<0.001)from T1 to T2. The alveolar width of the maxillary first premolar, the second primary molar and the first molar increased by(1.63±2.45)mm(P=0.010),(2.12±2.59)mm(P=0.002)and(1.98±2.10)mm(P<0.001)respectively. The width of the apex of the palatal root and the width of resistance center of the first molar increased by(2.00±2.40)mm(P=0.002)and(2.00±2.07)mm(P<0.001)respectively, with statistically significant differences. There was no statistically significant difference in.the tipping of the first maxillary molar(P=0.196, P=0.251), the width of the maxillary basal bone(P=0.192), the width of the mandibular basal bone(P=0.266)and the width of the center of resistance of the first molar(P=0.678), the height of the alveolar bone of the first maxillary molar(P=0.136), the second primary molar(P=0.638)and the first molar(P=0.274)and the location of the germ of the second premolar in alveolar bone(P=0.058)before and after treatment. Conclusion Rapid maxillary expansion combined with maxillary protraction can significantly improve the transverse deficiency of the middle-posterior arch and maxillary bone in mixed dentition patients with skeletal Class Ⅲ malocclusion. The treatment has no effect on the relative position of the premolar tooth germ in the alveolar bone.

    Objective To investigate the incidence and epidemic trend of food-borne diseases in Dezhou City by analyzing the data of active surveillance from 2019 to 2022, so as to provide scientific basis for government departments to formulate policies. Methods Surveillance data of food-borne diseases were collected and analyzed with χ2 tests. Results A total of 207,515 cases were monitored, the majority of which were middle-aged and elderly people aged 45-<75 years(106,131 cases, 51.23%), and mostly farmers(147,620 cases, 71.10%). The onset time was May to September. The main clinical manifestations were digestive system symptoms(203,425 cases, 98.03%). Up to 65,391 cases were exposed to fruit or fruit products(31.51%). In 92,370 cases(44.51%), the foods were processed at households; in 196,967 cases(94.92%), the foods were consumed at households. Conclusion Summer is the peak season for food-borne diseases, which occur mostly in farmers. Food-borne diseases occurring in households should be the focus of prevention and control, and publicity, education and monitoring should be targeted according to the epidemiological characteristics of food-borne diseases to reduce the prevalence.
