Objective To compare the effects of equivalent dose sufentanil,remifentanil or fentanyl on hemodynamic and cardiac output in the elderly patients during induction of general anesthesia.Methods Ninety elderly patients(ASA Ⅰ ～ Ⅱ) undergoing elective abdominal surgery under general anesthesia were randomly divided into sufentanil group(group S),remifentanil group(group R) and fentanyl group(group F),30 patients in each group.Patients in group S,group R and group F received sufentanil 0.2μg/kg,remifentanil 2μg/kg and fentanyl 2μg/kg Ⅳ,respectively,using an blind method before intubation.SBP,DBP,MAP,HR,CO,CI and SVR were recorded before of anesthesia (T0),immediately after induction (T1),1,3 minutes after tracheal intubation (T2,T3).Changes of SBP and HR during observation were also recorded.Results The MAP and HR in three groups at T1 were significantly lower than those at T0 and decreased significantly in group R than those in group F and S(P ＜0.05).The MAP and HR in group F significantly increased at T1 than T0.The MAP and HR in group R were significantly decreased after tracheal intubation.Compared with the baseline,the MAP and HR in group S at T1,T2,remained unchanged.In group R,there were two patients whose HR were under 50 bpm.In group F,the MAP at T1,T2 were significantly higher than those at T.In group S,there were no significant changes in CO,CI,SVR which were all within normal range (P ＞ 0.05).Conclusion Both sufentanil and remifentanil effectively inhibit the stress response during induction of general anesthesia.At the same time,sufentanil has better hemodynamic stability.

Objective To explore the correlation between TCM constitution and sleep status in escort troops. Methods Standardized TCM Constitution Questionnaire and Pittsburgh Sleep Quality Index (PSQI) were used to investigate escort troops. Factors of PSQI and constitution types were analyzed. Results The results of PSQI showed the number of escort troops who had bad sleeping (PSQI>7) was 64, which accounted for 46%of the escort troops, among which, 45 people (70.3%) were justified as biased constitution, while 19 were normal constitution (29.7%). The top three biased constitution in bad sleeping were:qi deficiency, phlegm-dampness and dampness-heat. PSQI factors such as sleep disorder, daytime dysfunction and total score had positive correlation with qi deficiency, yang deficiency, yin deficiency, dampness-heat and blood stasis, and negative correlation with normal constitution. Conclusion Sleep condition of escort troops has correlation with TCM constitution, which indicates that sleep status could be improved by regulating TCM constitution.

Objective To investigate the value of whole-tumor histogram analysis of quantitative perfusion in the prediction of ablation response in MR-guided high-intensity focused ultrasound (MR-HIFU)treatment for uterine fibroids.Methods A total of 31 fibroids in 28 eligible patients were treated with MR-HIFU.Four histogram parameters of the quantitative perfusion parameter (Ktrans )were obtained prior to MR-HIFU treatment:mean,median,skewness and kurtosis.T1 contrast-enhanced MRI immediately after MR-HIFU was performed to determine the non-perfused volume (NPV)and acquire non-perfused volume ratio (NPVR).The relationship between NPVR and all fibroid characteristics was determined by Spearman correlation analysis.Results The 3 1 fibroids were divided into high-response group and low-response group according to whether NPVR was higher than 60%.Four histogram metrics of Ktrans showed statistical difference between the two groups.The mean and median of Ktrans ,fibroid maximum diameter and T2 signal intensity type were correlated with NPVR.The Spearman correlation coefficient were －0.60,－0.66,－0.45 and －0.39,respectively (P＜0.05).Conclusion Uterine fibroids with lower whole-tumor Ktrans can achieve higher immediate ablation efficiency in MR-HIFU.Together with its histogram metrics,it might be a valuable indicator for patient selecting.

Objective:To evaluate the clinical relevant effect of hospital-wide blood glucose management in perioperative cholelithiasis patients with type 2 diabetes.Methods:The subjects of the study were patients with type 2 diabetes mellitus complicated with cholelithiasis who were treated at the Baiqiu'en Hospital in Shanxi from September 2022 to October 2023. The patients were divided into hospital-wide blood sugar management group and conventional treatment group, according to different blood glucose management they received. The differences in preoperative blood glucose control, length of stay, postoperative complications, and hospitalization expenses between the two groups were compared.Results:Compare based on the median (quartiles) of the observed indicators, patients with cholelithiasis who underwent hospital-wide blood glucose management based on insulin pumps had a higher proportion of time in range [72.00(70.21, 82.90)% vs. 64.80 (61.55,70.50)%, P<0.001)], lower average blood glucose level [9.00 (8.55, 10.44) mmol/L vs. 11.50 (10.50, 12.50) mmol/L, P<0.001], and shorter hospital stay [8.00 (7.00,13.00) days vs. 10.00 (8.00, 12.00) ) days, P<0.05]. Moreover, the incidence of postoperative complications was lower [5(11.11)% vs. 15(33.33)%, P<0.05], and hospitalization expenses were lower [16 535.34 (14 271.44, 29 569.23) yuan vs. 18 633.85 (17 482.66) yuan , 22 855.02) yuan, P<0.05] in patients who received hospital-wide blood glucose management. Conclusion:Hospital-wide blood glucose management based on insulin pumps showed favorable effects in the perioperative clinical application in cholelithiasis patients with type 2 diabetes, and could contribute to shortening the average length of stay, reducing hospitalization costs, and reducing postoperative complications.

Objective:To explore the material basis and molecular mechanism of Liu-He-Dan (LHD) in treating acute pancreatitis (AP).Methods:Active chemical components of LHD, their corresponding targets and related AP pathogenic genes were searched and selected in the Encyclopedia of Traditional Chinese Medicine (ETCM) and disease information related databases (OMIM, DisGeNET, HPO, and NCBI), respectively. The protein-protein interaction (PPI) was analyzed through the STRING database. Enrichment analysis on those targets was performed by using CPBD and STRING databases to examine the function and pathway involved in the treatment of AP by active chemical components of LHD. Finally, " Chinese medicinal materials-active chemical components-targets-pathways" network was constructed by Cytoscape 3.6.0.Results:Network analysis showed that a total of 111 active chemical components of LHD were correlated with 39 targets of AP. The gene ontology functional enrichment analysis of 39 targets by CPBD and STRING databases obtained 575 enrichment results of biological process, 49 results of molecular function and 26 results of cellular components; Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis obtained 46 enrichment results involved in pancreatic secretion, bile secretion, RRAR signaling pathway, arachidonic acid metabolism and calcium signaling.Conclusions:The molecular mechanism of LHD in the treatment of AP by multiple components, multiple targets and multi-signaling pathways was preliminarily determined, which provides a basis for further analysis on active chemical components of LHD and molecular function.

Objective:To analyze and compare the effects of conventional treatment and the dynamic 3C therapy, continuous glucose monitoring system, and on outcomes, length of hospital stay and medical costs in patients with type 2 diabetes mellitus.Methods:A total of 122 type 2 diabetes mellitus patients who visited the Department of Endocrinology of Shanxi Baiqiu'en Hospital between June 2022 and December 2022 were selected and randomized at 1:1 into the control group and the experimental group using the randomized numerical table method. The t-test and non-parametric test were used as appropriate to compare the glycemic control, length of hospital stay and medical costs of the two groups.Results:Before treatment, there was no significant difference in the indicators for blood glucose levels and fluctuations between the two groups ( P>0.05). After treatment, the glycosylated hemoglobin, fasting plasma glucose, and 2-hour postprandial blood glucose decreased in both groups. Moreover, the glycosylated hemoglobin, fasting plasma glucose, and 2-hour postprandial blood glucose showed more significant decreases in the experimental group compared with the control group after treatment. The glycemic variability indicators, including the time out of range, standard deviation of blood glucose, and the largest amplitude of glycemic excursion, decreased after treatment in both groups. The time in range increased after treatment. After treatment, the standard deviation of blood glucose and the largest amplitude of glycemic excursion in the experimental group were lower than those in the control group, and the length of hospital stay in the experimental group was shortened (all P<0.05). Conclusion:3C therapy contributes to better glycemic control and shorter hospital stay in patients with type 2 diabetes mellitus.
