This article was aimed to study effects of aqueous extracts and all chemical split fractions ofMori Cortex on hypoglycemic effect of diabetic mice model. Intra-peritoneal injection of 170 mg·kg-1 streptozocin (STZ) was given to male Kunming mice to establish type I diabetes mode. Continuous administration of medication was given for 4 weeks. And then, indicators such as body weight, water intake, food intake, fasting plasma glucose (FBG), insulin, C-peptide, total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-c), and low density lipoprotein cholesterol (LDL-c) were detected. Pathological morphology of the liver and pancreas were observed by light microscopy. The results showed that high-dose group ofM. Cortex aqueous extracts can improve weight loss of type I diabetic mice, significantly reduce water intake and food intake, reduce FBG, TC, TG and LDL-c levels in different degrees (P<0.05 orP<0.01), and increase C-peptide and HDL-c levels (P<0.05 orP<0.01). When dosages of 30% ethanol fraction and fatty oil fraction were only about 1/2 and 1/4 ofM.Cortex aqueous extracts, we found that it can improve lipid disorder status,repair liver cells, and improve liver tissue damage. Its effect was superior to M. Cortex aqueous extracts. It was concluded thatM. Cortexaqueous extracts showed a better hypoglycemic effect. The effective component parts were 30% ethanol fraction and fatty oil fraction. Its hypoglycemic mechanism may be related to the promotion of insulin secretion, regulation of blood lipid disorders, as well as the protection of liver structure and function.

Objective:To explore the correlation between the initial estimated glomerular filtration rate (eGFR) and all-cause mortality in end-stage renal disease (ESRD) patients undergoing urgent-start peritoneal dialysis (USPD).Methods:The clinical data of 380 ESRD patients undergoing USPD from January 2013 to June 2023 in Affiliated Hospital of Jining Medical University were retrospective analyzed. According to the median initial eGFR of 6.25 ml/(min·1.73 m 2), the patients were divided into low eGFR group with eGFR<6.25 ml/(min·1.73 m 2) and high eGFR group with eGFR ≥6.25 ml/(min·1.73 m 2), with 190 patients in each group. The baseline characteristics and hematological indexes within 48 h before USPD were compared between the two groups. The patients were followed up until death or until June 30, 2023, and all-cause mortality was recorded. The Kaplan-Meier survival curve was used to evaluate the accumulated survival rate. Multivariate Cox regression analyses were used to identify the independent risk factors for all-cause mortality in ESRD patients undergoing USPD, with subgroup analyses based on age, gender and diabetes. Results:The median follow-up time was 40.7 (21.7, 59.0) months, 112 patients died, with a total mortality rate of 29.5% (112/380). The blood potassium, blood phosphorus, urea nitrogen, uric acid, parathyroid hormone and dialysis age in high eGFR group were significantly lower than those in low eGFR group: (4.1 ± 0.7) mmol/L vs. (4.5 ± 0.8) mmol/L, (1.6 ± 0.4) mmol/L vs. (1.9 ± 0.6) mmol/L, (21.8 ± 7.2) mmol/L vs. (29.7 ± 11.0) mmol/L, (359.8 ± 99.4) μmol/L vs. (429.4 ± 116.9) μmol/L, 242.2 (151.5, 398.3) ng/L vs. 281.7 (189.1, 487.2) ng/L and 36.1 (18.8, 54.0) months vs. 43.7 (28.8, 68.2) months, the diabetes rate, hemoglobin, platelet count, blood chloride, fasting blood glucose and mortality rate were significantly higher than those in low eGFR group: 20.0% (38/190) vs. 11.6% (22/190), (100.6 ± 18.2) g/L vs. (96.1 ± 20.0) g/L, (207.7 ± 72.6) × 10 9/L vs. (192.4 ± 65.6) × 10 9/L, (100.6 ± 4.1) mmol/L vs. (99.4 ± 4.7) mmol/L, (5.9 ± 2.3) mmol/L vs. (5.5 ± 1.9) mmol/L and 34.2% (65/190) vs. 24.7% (47/190), and there were statistical differences ( P<0.01 or< 0.05). Kaplan-Meier survival curve analysis result showed that the all-cause mortality rate in high eGFR group was significantly higher than that in low eGFR group, and there was statistical difference (log-rank χ2 = 6.64, P<0.01). After adjusting for gender, age and confounding factors, multivariate Cox regression analysis result showed that elevated eGFR, increased mean corpuscular volume and elevated fasting blood glucose were independent risk factors for all-cause mortality in ESRD patients undergoing USPD ( HR = 1.14, 1.04 and 1.15; 95% CI 1.04 to 1.26, 1.01 to 1.08 and 1.03 to 1.29; P<0.01 or<0.05), while female was an independent protective factor ( HR = 0.59, 95% CI 0.38 to 0.92, P<0.05). Subgroup analysis result showed a consistent effect of eGFR on mortality in ESRD patients undergoing USPD. Conclusions:Higher initial eGFR in ESRD patients undergoing USPD is associated with an increased risk of all-cause mortality.

Objective To investigate the effect of respiratory movement of different amplitude,period and direction on the dose distribution of target area in dynamic intensity modulated radiation therapy.Methods A total of 30 cases of lung cancer were selected and divided into three groups according to the volume size of the target area,including groups A (72.0-200.2 cm3),B (271.7-380.0 cm3) and C (498.9-684.9 cm3).The average volume was 151.5,327.1 and 583.3 cm3,respectively.Breathing motion simulation platform was used to drive the mode body with two-dimensional ionization chamber matrix along the Gun-Target direction,then turn the collimator to 0° and 90°,respectively.The doses were collected at the central level in different amplitudes of 0,4,8,12 and 15 mm,periodic respiratory movement at the intervals of 3,4 and 5 s and respiratory motion measurement with a cycle of 4 s 5 times.The difference of dose distribution between the collected dose and TPS output was analyzed by taking the absolute dose and γ-passing rate (3 mm/3%) as indicators.Results In the two-sided upward,respiratory movement reduced the dose at the medial edge of the target area and increased the dose at the lateral edge of the target area.The difference of γ-passing rate between respiration cycle was up to 3.54% (t=2.301,P<0.05),and when the respiration movement was more than 8 mm,the γ-passing rate was less than 90% and decreased with the increase of amplitude.The difference of γ-passing rate between static and respiratory motion was negatively correlated with the volume of target area,and the average γ-passing rate of A,B and C three groups increased gradually.The γ-passing rate of 5 composited dose was higher than that of single dose,and the difference was statistically sigificant(t=-9.36--5.95,P<0.05).Conclusions The dose distribution of dynamic IMRT target area is mainly influenced by respiration range and its own volume,and the respiration cycle has an effect on dose distribution under partial amplitude.After implementing the multiple doses,some single dose implementation errors can be eliminated.Physicians need to expand the target area reasonably according to the range of respiratory movement,and optimize the amount of marginal tissue in the target area in the direction of respiratory movement.For patients with small target volume and large respiratory movement,respiratory management technology should be adopted to improve the accuracy of target dose implementation.
