Objective:To analyze the effects of different doses of butorphanol on prolactin, serotonin and lipid hydrogen peroxide after cesarean section.Methods:A total of 124 women who underwent cesarean section in the Affiliated Hospital of Jining Medical University from January 2023 to January 2024 were prospectatively selected as study subjects, and divided into the study group 1 (41 cases), study group 2 (41 cases) and study group 3 (42 cases) according to random number table method. All three groups underwent patient-controlled analgesia after surgery, and 0.2 mg fentanyl was used as analgesic drug. However, the doses of butorphanol were 100 mg/L in the study group 1, 120 mg/L in the study group 2, and 140 mg/L in the study group 3. The level of PRL and first lactation time before and after surgery were compared among the three groups at different time points, serotonin and LHP levels were compared among the three groups at different time points after surgery, Ramsay and visual analog scale (VAS) scores were compared among the three groups at different time points after surgery, and the occurrence of adverse reactions and satisfaction with analgesic effect were compared among the three groups.Results:At 24, 48 and 72 h after operation, the level of PRL in the study group 3 was higher than that in the study group 2 and study group 1: (383.02 ± 47.57) μg/L vs. (376.39 ± 46.83), (302.88 ± 41.38) μg/L; (412.38 ± 40.22) μg/L vs. (394.82 ± 38.30), (315.09 ± 37.93) μg/L; (434.39 ± 39.39) μg/L vs. (427.48 ± 40.27), (344.39 ± 42.78) μg/L, there were statistical differences ( P<0.05). The first lactation time in the study group 2 and study group 3 was lower than that in the study group 1: (50.31 ± 6.52), (49.54 ± 6.27) h vs. (53.91 ± 8.42) h, there was statistical difference ( P<0.05). At 2 h (T 1), 12 h (T 2), 24 h (T 3) and 48 h (T 4) after surgery, the levels of serotonin in the study group 3, study group 2 and study group 1 were increased successively, and the levels of LHP were decreased successively, there were statistical differences ( P<0.05). At 30 min after surgery (T 0), T 1, T 2, T 3 and T 4, the Ramsay score in the study group 3, study group 2 and study group 1 were increased successively, and the VAS score were decreased successively, there were statistical differences ( P<0.05). There was no significant difference in the incidence of adverse reactions among the three groups ( P>0.05). The total satisfaction of study group 3 was higher than that of study group 2 and study group 1: 92.86%(39/42) vs. 73.17%(30/41), 68.29%(28/41), there was statistical difference ( Z = 2.52, P = 0.008). Conclusions:Butorphanol 140 mg/L has a more significant analgesic effect after cesarean section, and can improve the levels of serum PRL, serotonin and LHP, reduce the occurrence of adverse reactions, and improve the satisfaction of analgesia

Objective:To explore the clinical application value of MRI-PDFF on different liver segments for the evaluation of non-alcoholic fatty liver disease (NAFLD).Methods:178 volunteers from March 2019 to February 2020 were included. PDFF values ??of all nine segments of the liver were measured using CSE3.0T MRI scan. The obtained average value was used to represent the average liver fat content. PDFF values of each or combined liver segment were equally compared with the average value to observe the representativeness of fat content. Receiver operating characteristic curve was used to analyze the diagnostic performance of each liver segment, and the Youden index was used to calculate the cutoff value. Paired-sample t-test or non-parametric Kruskal-Wallis test were used to compare measurement data among groups.Results:178 volunteers average liver fat content ranged from 0.89% to 42.61% with MRI-PDFF, and 71.35% (127/178) of the volunteers had PDFF > 5%. There was no significant difference between SIII, SIVb, SV, and SVIII liver segments when compared with the average value ( P > 0.05). PDFF values ??of SI, SII, and SIV a liver segments were all lower than the average value, while the PDFF values ??of SVI and SVII liver segments were all higher than the average value ( P ??< 0.05). MRI-PDFF sensitivity value for diagnosing liver steatosis of nine liver segments was 85.8% ~ 94.5%, and the specificity was higher than 96.0%. Among them, the SV liver segment had the highest sensitivity (94.5%), and the corresponding optimal diagnostic threshold value was 5.13%. Compared with single and combined liver segment, the PDFF value of SII, SV, SVI combined liver segment had the highest diagnostic performance for fatty liver, with the sensitivity and specificity of 96.9%, and 100%, respectively, and the corresponding optimal diagnostic threshold value was 5.17%. Conclusion:Compared with single and other combined liver segments, MRI-PDFF values of SII, SV, and SVI combined liver segments have higher sensitivity and specificity for the diagnosis of NAFLD, and it can be used as the first choice for the determination of liver fat content with MRI.

Objective To explore the prevalence and clinical characteristics of food allergy in bronchial asth-matic children less than 14 years old in China. Methods A case - controlled study was designed. The questionnaires were given to children,who were diagnosed to be asthmatic during the national epidemiological survey of asthma in chil-dren in 31 cities from September 2009 to August 2010. Non - asthmatic children,matched with the cases in age and gender,were selected during the same survey as control subjects if they were matched with the cases in age and sex. In-formation regarding the food allergen and symptom of food - induced anaphylaxis was analyzed. The difference in food allergy was compared between children with or without bronchial asthma. Results As a result,9235 asthmatic children and 11391 control subjects were enrolled in the case - control study. There were 14. 66％(1354 / 9235 cases)of the asthmatic children who had food allergy,compared to 3. 99％(455 / 11391 cases)of the non - asthmatics children, and the findings showed a significant difference (χ2 = 725. 25,P < 0. 001). The most common food allergens were fish and shrimp in both groups,and the difference was not significant [44. 09％ (597 / 1354 cases)vs. 42. 20％ (192 / 455 cases),χ2 = 0. 50,P > 0. 05]. The rate of peanut allergy was 4. 58％ (62 / 1354 cases)and 1. 54％ (7 / 455 cases) (χ2 = 8. 58,P < 0. 05),respectively. And the rates of fruit allergy in the asthmatic group and the non - asthmatic group were 14. 03％(190 / 1354 cases)and 27. 69％(126 / 455 cases)(χ2 = 44. 01,P < 0. 05),respectively. Cutaneous and nasal symptoms were common clinical manifestations. The rates of rash,pruritus,and swelling sympions were 47. 27％(640 / 1354 cases)and 61. 32％(279 / 455 cases)(χ2 = 26. 90,P < 0. 001),respectively for asthmatic group and non -asthmatic group. Rates of nasal symptoms were 17. 13％(232 / 1354 cases)and 10. 55％(48 / 455 cases)(χ2 = 11. 29, P = 0. 001),respectively in the asthmatic group and the non - asthmatic groups. Respiratory symptoms,such as cough and wheezing,were 25. 33％(343 / 1354 cases)and 5. 49％(25 / 455 cases)(χ2 = 80. 72,P < 0. 001)in 2 groups. Twenty cases of 1354 asthmatic children had severe food allergy,while such severe conditions occurred only 1 child without asthma (455 cases)occurred severe condition (1. 48％ vs. 0. 22％,χ2 = 4. 96,P < 0. 05). Conclusion The-rate of food allergen sensitization is highly prevalent in the children with asthma. Compared to those without asthma, and their types of food allergen and clinical symptoms are different from the latter.

Little is known about the effects of chronic alcohol intake on the outcome of acute kidney injury (AKI). Hence, we examined the effects of chronic alcohol intake on the development of renal fibrosis following AKI in an animal model of bilateral renal ischemia–reperfusion (IR) injury. We first found that chronic alcohol exposure exacerbated bilateral IR-induced renal fibrosis and renal function impairment. This phenomenon was associated with increased bilateral IR-induced extracellular matrix deposition and an increased myofibroblast population as well as increased bilateral IR-induced expression of fibrosis-related genes in the kidneys. To explore the mechanisms underlying this phenomenon, we showed that chronic alcohol exposure enhanced β-arrestin 2 (Arrb2) expression and Akt and glycogen synthase kinase-3 (GSK3)β activation in the kidneys. Importantly, pharmacological GSK3 inhibition alleviated bilateral IR-induced renal fibrosis and renal function impairment. Furthermore, we demonstrated that Arrb2(−/−) mice exhibited resistance to IR-induced renal fibrosis and renal function impairment following chronic alcohol exposure, and these effects were associated with attenuated GSK3β activation in the kidneys. Taken together, our results suggest that chronic alcohol exposure may potentiate AKI via β-arrestin 2/Akt/GSK3β-mediated signaling in the kidney.
