Objective To evaluate the efficacy and safety of low-dose erythromycin for the prevention of feeding intolerance in preterm infants. Methods Fifty-two preterm infants (30-31 weeks' GA group) and 68 preterm infants (32-34 weeks' GA group) were randomly subdivided into prevention groups and control groups. From the second day the prevention groups received intravenously erythromycin [3 mg /(kg·d)] for 10 days,the control groups received placebo of glucose. Results In 30-31 weeks' GA group,days to achieve full enteral feeding (DAFEF) ,days to regain birth weight (DRBW) and duration of hospitalization (DH) were shorter in the prevention group as compared to those in the control group, the incidence of feeding intolerance was lower too,but there was no significant difference (P >0.05). In 32-34 weeks' GA group, DAFEF [(13.8±4.5) d],DRBW [(10.5±1.6) d],DH [(28.5±6.8) d] were significantly shorter in the prevention group than those in the control group [(17.2±4.2), (13.8±1.5), (35.5±7.2) d],the incidence of feeding intolerance in the prevention group was lower too[ 17.6%(6/34) vs 35.3%( 12/34) ], there was significant difference (P < 0.05 ). Conclusion In 32-34 weeks' GA, low-dose erythromycin can be a safe and effective method to promote food tolerance in preterm infants, but not sure in 30-31 weeks' GA.

Objectives To explore the effect of transient continuous subcutaneous insulin infusion (CSII) on β cell function, insulin resistance and vascular endothelial injury in newly diagnosed type 2 diabetic patients and its potential mechanism. Methods Ten patients with newly diagnosed type 2 diabetes mellitus (T2DM) accepted CSII for two weeks. Intravenous glucose tolerance test (IVGTT) and hyperinsulinemia euglycemia clamp test were performed before and after CSII. Serum soluble E-selectin (sE-selectin) was used to evaluate the injury of vascular endothelial cell, while serum high sensitivity C reactive protein (hsCRP) and soluble CD_(14) (sCD_(14)) were both used to assess inflammatory condition. Results (1) Compared with those before treatment, the blood glucose levels of IVGTT, the area under the curve of the blood glucose, glycosylated hemoglobin, TC and LDL-C in the patients were decreased after CSII (P < 0. 05 or 0. 01). (2) Compared with those before treatment, the insulin levels of IVGTT (except the fasting insulin), the area under the curve of insulin and acute insulin response were all increased after CSII(P < 0.05 or 0.01). (3) Compared with that before treatment, the glucose infusion ratio in the clamp test [(3.46±1.66)mg·kg~(-1)·min~(-1) increased to (7.14±2.37)mg·kg~(-1)·min~(-1)]and HOMA-β elevated, while HOMA-IR declined (P <0. 05 or 0. 01 in all). (4) Compared with those before treatment, the levels of serum sE-selectin, sCD_(14) and hsCRP were decreased (P < 0. 01, except for hsCRP) . Conclusion Transient intensive insulin therapy in patients with newly diagnosed T2DM is useful to restore 13 cell function, attenuate insulin resistance, repair vascular endothelial injury and improve the disorder of blood sugar and lipid. The mechanism may be related with the inhibition of inflammation in patients.

Objective:To investigate the effects of preoperative administration of parecoxib sodium on stress reaction and postoperative nausea and vomiting score in patients undergoing laparoscopic cholecystectomy.Methods:A total of 112 patients undergoing laparoscopic cholecystectomy in Lishui City People's Hospital from January 2020 to January 2021 were included in this study. They were randomly divided into observation group and control group, with 56 patients per group. The observation group was intravenously administered 40 mg parecoxib sodium 30 minutes before surgery, and the control group was identically administered equal amount of 0.9% sodium chloride injection. At 1, 6, 12 and 24 hours after surgery, Visual Analogue Scale (VAS) score, cortisol and adrenocorticotropic hormone levels and postoperative nausea and vomiting score were compared between the two groups.Results:At 1, 6 and 12 hours after surgery, VAS score in the observation group was (3.23 ± 0.85) points, (2.44 ± 0.76) points, (2.37 ± 0.69) points, respectively, which were significantly lower than (4.06 ± 1.12) points, (3.24 ± 0.95) points, (3.10 ± 1.07) points in the control group ( t = 4.41, 4.92, 4.29, all P < 0.001). At 1, 6, 12 and 24 hours after surgery, cortisol level in the observation group was (287.79 ± 35.46) ng/L, (303.55 ± 34.77) ng/L, (368.58 ± 31.22) ng/L, (397.16 ± 32.60) ng/L, respectively, which were significantly lower than (337.64 ± 39.52) ng/L, (364.18 ± 36.90) ng/L, (405.56 ± 37.29) ng/L, (455.51 ± 37.81) ng/L in the control group ( t = 7.02, 8.94, 5.69, 8.74, all P < 0.05). At 1, 6, 12 and 24 hours after surgery, adrenocorticotropic hormone level in the observation group was (59.25 ± 7.63) ng/L, (65.27 ± 8.23) ng/L, (72.29 ± 7.49) ng/L, (83.63 ± 8.57) ng/L, which were significantly lower than (64.48 ± 8.06) ng/L, (71.44 ± 8.59) ng/L, (79.79 ± 8.15) ng/L, (90.08 ± 8.26) ng/L in the control group ( t = 3.52, 3.88, 5.07, 4.05, all P < 0.05). Within 24 hours after surgery, the incidence of postoperative nausea and vomiting in the observation group was significantly lower than that in the control group [12.50% (7/56) vs. 28.57% (16/56), χ2 = 4.43, P < 0.05). Within 2 hours, 2-6 hours, and > 6-24 hours, postoperative nausea and vomiting score in the observation group was (1.31 ± 0.26) points, (1.43 ± 0.32) points, and (1.46 ± 0.41) points, respectively, which was significantly lower than (1.67 ± 0.41) points, (1.83 ± 0.39) points, (1.88 ± 0.44) points in the control group ( t = 2.12, 2.37, 2.14, all P < 0.05). Conclusion:Preoperative administration of parecoxib sodium exhibits a good postoperative analgesic effect in patients undergoing laparoscopic cholecystectomy. It can effectively reduce postoperative stress reactions, decrease the incidence of postoperative nausea and vomiting, and lower the severity of postoperative nausea and vomiting, and thereby can be widely used in clinical practice.

Objective:To explore the postprandial plasma low-density lipoprotein cholesterol (LDL-C) changes by various detection methods.Methods:A total of 85 subjects admitted to the Second Xiangya Hospital of Central South University from November 2017 to May 2019 were included. Serum samples were collected from fasting and the 2 nd hour and the 4 th hour after breakfast. Serum lipid levels were measured with enzymatic assays and nuclear magnetic resonance spectroscopy (NMRS), and proprotein invertase subtilisin/kexin type 9 (PCSK9) levels were measured with enzyme-linked immunosorbent assays. The differences of blood lipid components at different time points were compared by Friedman two-way rank analysis of variance and Wilcoxon signed rank test, and the correlation between PCSK9 level and lipoprotein particles was analyzed by Spearman correlation. Results:Measured by enzymatic assays, compared with the fasting state, LDL-C decreased at the 2 nd hour and the 4 th hour after the meal (2.58[2.09, 3.12], 2.47[1.92, 3.02], 2.37[1.82, 2.80] mmol/L, P<0.001). Measured by NMRS, the concentration of LDL particles (1 086[830, 1 239], 1 083[848, 1 213], 1 061[814, 1 213] nmol/L, P=0.417) did not change significantly, and cholesterol in LDL particles were 2.13 (1.56, 2.54), 2.16 (1.68, 2.50), 2.06 (1.58, 2.50) mmol/L, respectively ( P=0.047),and postprandial cholesterol in LDL particles in the 2 nd hour and in the 4 th hour did not change significantly compared with fasting ( P>0.05). while the concentration of large LDL particles (185.2[150.6,221.6], 173.0[144.8,220.3], 178.1[144.0,233.6] nmol/L, P=0.001), and the cholesterol level in large LDL particles (0.49[0.39, 0.57], 0.47[0.38, 0.57], 0.46[0.37, 0.58]mmol/L, P<0.001) decreased after the meal. The PCSK9 level also decreased significantly after the meal (299[233, 397], 257[208, 342], 251[215, 340] ng/ml, P<0.001). There was an independent positive correlation between the decrease of PCSK9 levels and the increase of remnant cholesterol detected by MNRS after the meal ( r=0.232, P=0.035). Conclusions:The postprandial LDL-C level measured by NMRS and enzymatic assays is not consistent. The decrease of LDL-C measured by enzymatic assays is not caused by the clearance of LDL particles, but by the redistribution of cholesterol in each LDL subfraction.
