Objectives: The b-value in the Gutenberg-Richter relation is often used as an essential indicator for estimating the magnitude of regional stress, and it plays a vital role in evaluating the probability of earth-quake occurrence. At 02:04:11 on May 22th, 2021, an Mw 7.4 earthquake occurred in Maduo County, Qing-hai Province. The Maduo earthquake unexpectedly occurred inside the Bayan Har block, and located in Kunlun-Jiangcuo fault,which is a secondary fault in south of the East Kunlun fault. Methods: To reveal the seismogenic environment of the source region before the Maduo earthquake and the evolution of the after-shocks, the distribution and change of b-value before the Maduo earthquake are investigated by using the earthquake catalog provided by the China Earthquake Networks Center from January 1, 2009 to May 20, 2021. The catalog includes 32 230 well-located events with a complete magnitude. Results: The results indicate that b-value in the source area is extremely low before the 2021 Maduo earthquake, indicating a significant stress accumulation in the source region. Moreover, there is a noticeable decrease in b-value in the source region before the 2021 event. Conclusions: The b-value is an essential indicator of the upcoming great earthquake and has excellent potential for predicting a future large earthquake within the block. More‐ over, the early b-value variations are of guiding significance to the location prediction of aftershock in the future. [ABSTRACT FROM AUTHOR]

To investigate the effects of quercetin on oxidative stress and endoplasmic retic‑ ulum stress of human umbilical vein endothelial cells（HUVECs）induced by high glucose and their pos‑ sible mechanism. Methods HUVECs were cultured in vitro，and the cells were divided into the control group（Control group），high glucose（HG）group，and quercetin groups with different concentrations （20 µmol/L，50 µmol/L，and 100 µmol/L，named as Q20，Q50，Q100 groups），respectively. HU‑ VECs in the Q20 group were pretreated with 20 µmol/L quercetin for 1 h，and then were added with 10 mg/L glucose for culture. HUVECs in the Q50 group were pretreated with 50 µmol/L quercetin for 1 h，and then were added with glucose for culture. HUVECs in the Q100 group were pretreated with 100 µmol/L quercetin for 1 h，and then were added with 10 mg/L glucose for culture. In the HG group， 10 mg/L HG was added to the culture medium，and the cells in the Control group were cultured in the low-glucose DMEM medium. After 24 hours of intervention，the cell viability was detected by cell count‑ ing Kit-8（CCK-8）method. The apoptosis rate and reactive oxygen species（ROS）level were detected by flow cytometry. The degree of cell membrane damage was evaluated by detecting lactate dehydrogenase （LDH）activity in the media. Western blotting was used to detect the expression levels of glucose-regulat‑ ed protein 78 （GRP78），CCAAT/enhancer-binding protein homologous protein （CHOP） and Cas‑ pase12. Results Compared with the Control group，the activity of endothelial cells in the HG group de‑ creased after 24 h（P<0. 05）. Compared with the HG group，the activity of endothelial cells in the Q20， Q50 and Q100 groups increased，and the cell viability increased with the increased concentrations of quercetin（all P<0. 05）. Compared with the Control group，the apoptosis rate of the HG group increased （P<0. 05），while the apoptosis rates of the Q20，Q50 and Q100 groups decreased，and the apoptosis rate decreased with the increased concentrations of quercetin（all P<0. 05）. Compared with the Control group，the ROS in the HG group increased（P<0. 05）；compared with the HG group，the ROS in the Q20，Q50 and Q100 groups decreased，and the ROS decreased with the increased concentrations of quer‑ cetin（all P<0. 05）. Compared with the Control group，the LDH activity in the cell culture medium of the HG group increased（P<0. 05）. Compared with the HG group，the LDH activity in the cell culture medi‑ um of the Q50 group and Q100 group decreased （both P<0. 05）. Compared with the Q50 group， the LDH activity in the cell culture medium of the Q100 group decreased（P<0. 05）. Compared with the Control group，the expression levels of GRP78，CHOP，and Caspase 12 in the endothelial cells of the HG group increased（all P<0. 01）. Compared with the HG group，the expression levels of GRP78， CHOP，and Caspase 12 decreased in the endothelial cells of the Q20，Q50 and Q100 groups（all P< 0. 01）. Conclusions Quercetin can increase endothelial cell activity，reduce LDH activity，inhibit the apoptosis，reduce ROS content，and inhibit the expression levels of GRP78，CHOP and Caspase 12 of endothelial cells in the high glucose solution，and its inhibitory effect is enhanced with the increased con‑ centrations of quercetin. Quercetin may play a protective effect on endothelial cells by inhibiting endothe‑ lial cell oxidative stress，endoplasmic reticulum stress and reducing apoptosis under the condition of high glucose.

Objective To investigate the compliance of postoperative cervical cancer patients with home rehabilitation. Methods A total of 50 patients with cervical cancer admitted to a tertiary hospital in Chongqing from June to December 2021 were selected, and a self-designed questionnaire was used to investigate, and general condition and rehabilitation compliance of the patients were analyzed. Results The scoring rates of healthy lifestyle and lifestyle compliance were greater than 70.00%.The scoring rates of disease rehabilitation compliance from high to low were medication, follow-up, condition observation, wound care, functional exercise, pelvic floor rehabilitation and sexual life. The score rates of intermittent catheterization compliance were low. The score rates of health belief compliance were more than 87.00%.The scores of rehabilitation compliance of patients with different marital status were compared, and the difference was statistically significant (P<0.05). Conclusion The compliance of patients with cervical cancer during home rehabilitation is low, such as disease rehabilitation and intermittent catheterization. Medical staffs should take effective measures to improve the compliance of patients with home rehabilitation. [ABSTRACT FROM AUTHOR]

In the flood seasons of 2018 and 2019, the inflow of Xiaolangdi Reservoir was higher than before and it was the first time that the operation of low reservoir level, long duration,large discharge, and high sediment concentration was applied for two consecutive years, which effectively scoured the sediment in the reservoir area. This paper analyzed the influencing factor of sediment discharge and established the calculation formula of the reservoir sediment discharge ratio by the regression analysis method, based on the actual sediment discharge operation of the reservoir. The results point out that pondage, lowest water depth and inflow are most closely related to sediment discharging, with a high correlation above 0.80. The calculation formula for the sediment discharge ratio verified by the measured data can simulate the sediment discharge of the reservoir well. Based on the observation data of the topography of the reservoir dam area, the sediment scour and silting change in the dam area were analyzed, and it was proposed that the river bed gradient within 4.5 km of the reservoir area had been stabilized between 4.3‰ and 5.1‰ since 2014, under the influence by the discharge bottom hole. The lowest elevation of sediment deposition in front of the intake tower varies between 176 m and 181 m. On the right bank in front of the dam, the sediment deposition elevation gradually rises and the slope becomes steeper. Currently, a stable slope has not been formed. As the left bank in front of the dam is close to the mountain with a high slope and there is little sediment accumulation. [ABSTRACT FROM AUTHOR]

Preventing sediment siltation in front of intake tower group of the Xiaolangdi Reservoir affects the safety operation and the generation benefits of the project. It is vital to determine a proper operation dispatch scheme of the outlet structures. This paper did the numerical research on the prevention of silt plug in the Xiaolangdi Reservoir by a vertical 2D numerical model. The bed evolution, sediment delivery ratio and generation benefit were discussed under typical water and sediment conditions with the two different dispatch schemes of the outlets. The results of the numerical modeling show that neither of the dispatch schemes will cause the sediment siltation and the scheme I shows a better performance in promoting the generation benefits. The present work provides the technical support for the operation dispatch scheme of outlets in engineering practices. [ABSTRACT FROM AUTHOR]

Objective To investigate glucose metabolism and insulin secretion in patients with chronic hepatitis B (CHB) of different Child-Pugh grades and liver cirrhosis and their association with inflammatory response. MethodsA total of 147 patients with CHB and liver cirrhosis who were admitted to Guangzhou Red Cross Hospital from January 2013 to January 2018 were enrolled, and 65 healthy individuals who underwent physical examination in our hospital during the same period of time were enrolled as control group. The clinical data within 12 hours after admission were collected, including age, sex, body mass index, systolic pressure, diastolic pressure, HBV DNA load, total cholesterol, triglyceride, low-density lipoprotein, high-density lipoprotein, alanine aminotransferase, aspartate aminotransferase, tumor necrosis factor α (TNFα), neutrophil-lymphocyte ratio (NLR), fasting blood glucose, plasma insulin, C-peptide level, homeostasis model assessment of insulin resistance (HOMA-IR), and insulin secretion function. Blood glucose, insulin, and C-peptide were recorded at 2 hours after oral glucose tolerance test (OGTT). The chi-square test was used for comparison of categorical data between two groups; the t-test was used for comparison of continuous data between two groups; the Kruskal-Wallis H test was used for comparison of ranked data between multiple groups and further comparison between two groups. A Pearson correlation analysis was used to investigate correlation. ResultsCompared with the control group, the patients with CHB and liver cirrhosis had significantly higher TNFα, interleukin-6 (IL-6), NLR, insulin, and HOMA-IR (all P＜0.05) and significantly lower insulin secretion function (P＜0.05). The 147 patients with CHB and liver cirrhosis were divided into Child-Pugh A, B, and C groups according to Child-Pugh grade, and there were significant differences in TNFα, IL-6, NLR, insulin, HOMA-IR, and insulin secretion function between these three groups (all P＜005). Compared with the control group, the patients with CHB and liver cirrhosis had significantly higher blood glucose, insulin, C-peptide, NLR, TNFα, and IL-6 at 2 hours after OGTT (all P＜0.05); there were significant differences in blood glucose, insulin, NLR, TNFα, and IL-6 at 2 hours after OGTT between the three groups with different Child-Pugh grades (all P＜0.05). Child-Pugh score was positively correlated with NLR and blood glucose and insulin at 2 hours after OGTT (r=0.678, 0.451, and 0.644, all P＜0.001), and NLR was positively correlated with blood glucose and insulin at 2 hours after OGTT (r=0.408 and 0.795, both P＜0.001). ConclusionThere is a certain degree of abnormal glucose metabolism and insulin resistance in CHB patients with liver cirrhosis, and the severities of abnormal glucose metabolism and insulin resistance increase with the increase in liver injury, while inflammation may mediate the association between them.
