The effect of myocardium subjected to 60 min ischemia and 60 min reperfusion on the level of lipid peroxides (LPO) and function of myocardial mitochondria and activity of superoxide dismutase (SOD) was studied in cat cardiopulmonary bypass. Myocardial mitochondrial function was slightly depressed after 60 min ischemia but significantly depressed after 60 min reperfusion. Increased lipid peroxides content and decreased SOD activity were observed at 60 min ischemia. After reperfusion, the SOD activity continued decreasing, but LPO elevated apparently. These results support a hypothesis that the free radicals may contribute to the myocardial mitochondrial reperfusion injury.

To search for potent drugs against non-small-cell lung cancer(NSCLC),a series of hybrids(9a-9e, 10a-10e and 11a-11e﹚ from anilinopyrimidines and diazeniumdiolates were designed and synthesized.The MTT assay was employed to evaluate their antiproliferative activity against H1975 cells harboring epithelial growth factor receptor(EGFR)L858R/T790M mutation.The results showed that compounds 9a-9e displayed remarkable inhibitory activity on H1975 cells.Among these compounds, the most potent was compound 9b(IC50=0.65 μmol/L),which was superior to the positive control gefitinib.Additionally,molecular docking study indicated that 9b could bind with EGFR T790M by forming hydrogen bond, electrostatic interactions, et al, suggesting that compound 9b may be a potential anti-NSCLC agent for further investigation.

Objective To investigate the effect of Yam gruel on postoperative incision healing in patients with Type Ⅱ diabetes and complicated with colorectal cancer,hence to provide a better diet plan for postoperative incision healing.Methods A convenience sampling method was used to select 92 patients with Type Ⅱ diabetes who were complicated with colorectal cancer and underwent surgery of laparoscopic radical resection for colorectal cancer in a general hospital in Fujian province.IBM SPSS 25.0 software was used to randomly divide the patients into control group and trial group,with 46 patients per group.Conventional postoperative treatment and care was offered to the patients in control group,while patients in the trial group,after anal exhaust,consumed Yam gruel made from Chinese Yam along with the remaining breakfast after deducting an 84 kcal of energy produced by the gruel for 3 weeks.The two groups were compared in terms of the post-intervention healing time,healing grade,incidence of poor incision healing,and changes in blood glucose before intervention,at 1 week and 3 weeks post-intervention.Results Forty-four patients completed the trial in the trial group,with two left at the third week of intervention.A total of 45 patients completed the study in the control group,with one dropped out of the follow-up after 3 weeks of intervention.After intervention,the incision healing time in the trial group was significantly shorter than that of the control group(P<0.05).Additionally,the healing grade was better(P<0.05),and the incidence of incision infections was significantly lower than that of the control group(P<0.05).Repeated measures ANOVA revealed that there were statistically significances in both groups in either main effects on fasting blood glucose and blood glucose at 2 hours after breakfast(all P<0.001).Particularly,at Week 1 and Week 3 post-intervention,the trial group showed both lower fasting blood glucose and blood glucose at 2 hours after breakfast compared with those in the control group(both P<0.01).Conclusion Yam gruel can reduce the time for incision healing,improve the quality of incision healing and regulate blood sugar.

Objective To explore the role of impulsivity in manic episodes of bipolar I disorder and cognitive impairment. Methods Sixty-one patients with bipolar I manic-episode ( study group) and 43 healthy volunteers (control group) were included in the study,and the cognitive function and impulsivity of the subjects were assessed using the MATRICS consensus cognitive battery (MCCB) and BIS-11 impulsivity scale (BIS-11). The differences in impulsivity and cognitive function between the study group and control group were compared. Partial correlation analysis was used to analyze the correlation between impulsivity and cognitive function in patients with bipolar I manic episode. Results ( 1) The scores of several cognitive function in study group,were significantly lower than those in healthy control group including information pro-cessing speed,attention alertness,word learning,visual learning,working memory,reasoning and problem sol-ving (all P<0. 01). (2)The total score,motor factor score and cognitive factor score of BIS-11 impulse scale in study group were significantly higher than those in control group (58. 39±15. 77 vs 48. 02±11. 16,62. 09± 19. 01 vs 44. 24±21. 09,56. 97±16. 57 vs 50. 06±13. 87,all P<0. 05). Increased overall scores on the bis-11 impulse inventory may be a risk factor for bipolar I episodes( OR=1. 204,95% CI=1. 032-1. 404). (3) In study group,the total score of BIS-11 was negatively correlated with the speed of information processing, working memory,word learning,reasoning and problem solving,and the total score of MCCB(r=-0. 417,-0. 360,-0. 294,-0. 348,-0. 348,P<0. 05). The score of unplanned factor was negatively correlated with the speed of information processing,word learning,the total score of MCCB(r=-0. 397,-0. 302,-0. 358,P<0. 05). The score of cognitive factor was negatively correlated with the speed of information processing,work-ing memory,word learning,reasoning and problem solving,and the total score of MCCB(r=-0. 327,-0. 351,-0. 374,-0. 391,-0. 463,P<0. 05). The score of motor factor was negatively correlated with working memo-ry and the total score of MCCB(r=0. 370,r=0. 389,P<0. 05). Conclusion High impulsivity is a risk factor for manic episodes of bipolar I disorder and may be associated with cognitive impairment in patients with ma-nic episodes of bipolar I disorder.

Objective:To investigate the risk factors of olfactory dysfunction (OD) of female patients with primary Sj?gren′s syndrome (pSS) and a prediction model was constructed.Methods:A total of 252 female pSS patients in the Third Municipal Hospital of Huzhou, from January 2021 to 2023 were recruited. According to the olfactory function,they were divided into OD group (144 cases) and without OD group (108 cases).The independent risk factors of OD were evaluated and the clinical prediction efficiency of the model was analyzed by receiver operating characteristic (ROC) curve, Hosmer-Lemeshow goodness-of-fit test and the decision curve analysis (DCA) curve.Results:The rate of OD was 57.1%((144/252)) in female pSS patients. Hyposmia was the main olfactory disorder in OD group (140/144, 97.2%). Univariate analysis showed that there were significant differences between OD and without OD groups, including disease course ( t=-2.05, P=0.040), RF( t=2.90, P=0.004), IgG( t=4.41, P=0.001), C3( t=5.47, P=0.001), ESSPRI( t=2.55, P=0.011), ESSDAI( t=3.80, P=0.001), HAMD ( t=3.38, P=0.001). Logistic regression analysis showed that high serum RF, IgG and low complement 3, high scores of ESSDAI and HAMD high scores were independent risk factors for pSS patients with OD patients[ OR(95% CI)=1.01(1.01, 1.03), 1.21(1.06, 1.38), 0.98(0.96, 0.89), 1.52 (1.20, 1.92), 1.13(1.03, 1.23)] ( P value were 0.016, 0.005, 0.004, <0.001 and 0.007 respectively). Based on the above independent risk factors, we constructed the prediction model nomogram and performed the internal data validation. The ROC curve AUC (95% CI) of the modeling group was 0.83(0.77, 0.89) and validation group was 0.69(0.57, 0.82), the prediction model was well differentiated.Hosmer-Lemeshow goodness-of-fit test showed that the prediction model had good calibration ability ( P=0.083), and the DCA curve display model is clinically valuable. Conclusion:The clinical prediction model developed in this study can be used to assess the risk of pSS-OD development, which is helpful for early detection and timely interention so can improve the quality of life of pSS-OD patients in turn.

Objective To describe the cardiovascular risk profile of inpatients with schizophrenia and estimate the 10-year CVD risk in schizophrenia patients. Methods Four hundred sixty-six randomly selected cases of schizophrenia patients and 507 health controls were included in the study. Body mass index (BMI), Fasting blood glucose (FBG), triglyceride (TG),,total cholesterol (TC), smoking rate (smoking people/total people), Framing-ham Risk Score (FRS), high density lipoprotein-cholesterol (HDL-C) and age of the vessel (VA). The 10-year cardiovascular risk(FRS) and age of the vessel (VA) were assessed using the Framing-ham Risk Score. Results 10-year CVD risk was significantly higher in patients with schizophrenia than in control group [(6.71 ±6.95)％ vs. (4.76 ±3.07)％], (P<0.05). Comparing with the control group, smoking prevalence[(41％) vs. (19％)], MS[(25％) vs. (17％)], BMI[(23.67 ±3.61)kg/m2 vs. (21.73±4.11)kg/m2] and VA[(46.7±15.3) vs. (43.7±9.8)] were higher in patients group. SBP[(119.86±14.90)mmHg vs. (128.10±15.41)mmHg] and HDL-C [(1.08±0.27)mmol/L vs. (1.38±0.22)mmol/L] were lower in patients group than in the healthy controls. The FRS score of the patient group was positively correlated with BMI, FBG level and SBP, waist circumference and smoking index (P<0.05) and was negatively correlated with the levels of HDL-C. Multivariate Linear Regression analysis demonstrated that FRS was correlated with FBG (β=0.181,P<0.01)、SBP (β=0.149,P<0.01)、HDL-C (β=-0.107,P<0.01) and smoking index(β=0.554,P<0.01). Conclusion The risk of cardiovascular disease in patients with schizophrenia over the next 10 years is 6.7％, which is significantly higher compared with the control group. Fasting blood glucose, systolic blood pressure, high density lipoprotein, smoking may be associated with 10-year CVD risk of schizophrenia patients.

Background::Gastric cancer (GC), a malignant tumor with poor prognosis, is one of the leading causes of cancer-related deaths worldwide; consequently, identifying novel therapeutic targets is crucial for its corresponding treatment. NUF2, a component of the NDC80 kinetochore complex, promotes cancer progression in multiple malignancies. Therefore, this study aimed to explore the potential of NUF2 as a therapeutic target to inhibit GC progression. Methods::Clinical samples were obtained from patients who underwent radical resection of GC at Lanzhou University Second Hospital from 2016 to 2021. Cell count assays, colony formation assays, and cell-derived xenotransplantation (CDX) models were used to determine the effects of NUF2 on GC progression. Flow cytometry was used to detect the effect of NUF2 or quercetin on cell cycle progression and apoptosis. A live-cell time-lapse imaging assay was performed to determine the effect of NUF2 on the regulation of mitotic progression. Transcriptomics was used to investigate the NUF2-associated molecular mechanisms. Virtual docking and microscale thermophoresis were used to identify NUF2 inhibitors. Finally, CDX, organoid, and patient-derived xenograft (PDX) models were used to examine the efficacy of the NUF2 inhibitor in GC. Results::NUF2 expression was significantly increased in GC and was negatively correlated with prognosis. The deletion of NUF2 suppressed GC progression both in vivo and in vitro. NUF2 significantly regulated the mitogen-activated protein kinase (MAPK) pathway, promoted G2/M phase transition, and inhibited apoptosis in GC cells. Additionally, quercetin was identified as a selective NUF2 inhibitor with low toxicity that significantly suppressed tumor growth in GC cells, organoids, CDX, and PDX models. Conclusions::Collectively, NUF2-mediated G2/M phase transition and apoptosis inhibition promoted GC progression; additionally, NUF2 inhibitors exhibited potent anti-GC activity. This study provides a new strategy for targeting NUF2 to suppress GC progression in clinical settings.
