In order to effectively manage the groundwater, this paper provided a method of choosing the monitoring wells and determining controlled and assessed water level in over-exploitation areas from the perspective of regional and depression cone areas control. For the whole over-exploitation areas, Thiessen polygon method was used to assign control areas to each observation well, and the ratio of the control area of each well to the total area of the region was used as a weight to calculate the weighted average water level of the areas. Then, according to the proximity to the average water level, one regional water level of the controlled well was selected, regarding the water level of the controlled well at the end of the most recent normal year as the controlled and assessed water level. However, if the assessed year was a dry year, assessed water level should set slackness. For groundwater depression cone areas, it used the water level contour map to judge the distribution of the depression cone, and then chose a controlled well which was located near the center of the cone. Then, it similarly regarded the water level of the controlled well at the end of the most recent normal year as controlled and assessed water level. Applying this method to Guantao County, Hebei Province, the monitoring wells of W16 and W17 were selected as regional and depression cone areas of the controlled wells respectively. When the government had not formulated a plan for the water level recovery, the regional controlled water level was determined as 17.13 m. When the government had formulated a plan for the water level recovery (for example, the water level was recovered by 0.5 m within 5 years), the regional controlled water level was needed to increase by 0.1 m every year on the basis of 17.13 m. The assessed water level was equal to the controlled water level in wet and normal years, but the assessed water level in dry years was equal to the controlled water level minus 0.93 m (slackness). The controlled and assessed water levels in the depression cone areas were all determined to be 12.19 m. [ABSTRACT FROM AUTHOR]

Objective To investigate the effect of Life′s Simple 7 (LS7) intervention on chemotherapy-related cardiovascular system damage in HER2 positive patients with breast cancer after radical surgery. Methods A total of 120 HER2 positive patients who received standardized chemotherapy for breast cancer were randomly divided into control group and LS7 group. The control group was addressed with standard chemotherapy scheme, and LS7 group was treated with LS7 intervention for 12 months on the basis of the control group. The improvement effect of cardiovascular system damage in the two groups was evaluated by comparing the degree of cardiovascular system damage, anxiety, depression, and quality of life before and after treatment. Results Compared with the control group, the LS7 group had better overall LS7 score and 7 cardiovascular health indicators (P < 0.05). The LS7 group had higher LVEF (P < 0.05), lower NT-proBNP (P < 0.05), lower anxiety and depression score (P < 0.05), and higher quality of life score (P < 0.05). Conclusion LS7 intervention can significantly reduce chemotherapy-related cardiovascular system damage in HER2 positive breast cancer patients and improve the mental health and quality of life of breast cancer patients, which is worthy of clinical promotion.

BACKGROUND: In recent years, there have been many studies on the prevention and treatment of femoral head necrosis with traditional Chinese medicine. A variety of single Chinese medicines, Chinese medicine monomers and Chinese medicine compounds can regulate bone metabolism, lipid metabolism, and oxidative stress by targeting signaling molecules. The prevention and treatment of femoral head necrosis by translation-related signaling pathways has become a research hotspot. OBJECTIVE: To expound the global research progress in hormone-induced femoral head necrosis treated with Chinese medicine, in order to provide some ideas for the treatment of hormone-induced femoral head necrosis. METHODS: CNKI, WanFang, VIP, SinoMed, PubMed, Embase, and Web of Science databases were searched with the search terms “glucocorticoids, avascular necrosis of the femoral head, ANFH, pathogenesis, signal path, Chinese medicine compound, oxidative stress” in Chinese and English. Literature was retrieved on Chinese medicine compounds and active ingredients for intervention of the signaling pathway related to hormone-induced femoral head necrosis. A total of 71 documents were included according to the inclusion and exclusion criteria. RESULTS AND CONCLUSION: Chinese medicine may treat hormone-induced femoral head necrosis through multiple signaling pathways. Total saponins of Panax notoginseng, total flavonoids of Rhizoma Drynariae, and resveratrol glucoside promote osteoblast proliferation and differentiation and inhibit osteoclast formation by regulating the level of β-catenin protein and the formation of β-catenin-TCF/LEF complex via the Wnt/β-catenin signaling pathway. Recipes for invigorating blood and reinforcing marrow, warming yang and tonifying kidney, and relieving bone bi-syndrome maintain osteoblast-osteoclast dynamic balance and bone homeostasis by regulating the OPG/RANK/RANKL pathway. Puerarin, salidroside, allicin, and icariin influence the proliferation and apoptosis of osseous cells and angiogenesis of microvascular endothelial cells in the femoral head via the PI3K/Akt signaling pathway. Ginsenosides can down-regulate the expressions of superoxide dismutase and catalase by interfering with the Keapl-Nrf2-ARE signaling pathway, thereby attenuating oxidative stress damage. Gastrodin, lutein, and astragaloside IV can promote the proliferation and differentiation of osteoblasts by intervening Nrf2/HO-1 signaling, thereby improving the level of oxidative substances. Naringin and polygonin balance the osteogenic/adipogenic differentiation of bone marrow mesenchymal stem cells via the Nrf2/ARE signaling pathway. Traditional Chinese medicine can regulate oxidative stress response of osteocytes, which is another important way to treat hormone-induced necrosis of the femoral head. [ABSTRACT FROM AUTHOR]

Objective In the gathering and transportation of natural gas mines with high hydrogen sulfide content, in order to effectively reduce the corrosion hazard of hydrogen sulfide to the system, dehydration is often used to control the water dew point. Methods Based on the research of dehydration technology of high sulfur natural gas at home and abroad, triethylene glycol solvent absorption method was selected as the dehydration treatment process of high sulfur natural gas in Shunbei No. 2 area. Considering the characteristics of high sulfur natural gas in Shunbei No. 2 area, the traditional triethylene glycol dehydration process was optimized and improved locally, and the separation process before the raw gas inlet adsorption tower and the flash-vapor recovery process were added at the same time. Based on the influence of the pre-heating location, regeneration purity and hydrogen sulfide, the paper adopted a two-stage low-liquid/high-liquid heat exchange pre-heating process and LNG gasification gas extraction process to form a dehydration process which is suitable for high-sulfur natural gas in Shunbei No. 2 area. Results After transformation, the dehydration process realized zero discharge of sulfur-containing tail gas from dehydration system by pressurized recovery, and the combination of efficient desulfurization and purification of triethylene glycol (TEG) realized by LNG gasification and gas stripping, the problem of corrosion and maintenance of regeneration device in acid environment was solved. Conclusions This dehydration process effectively promoted the realization of the overall development plan of Shunbei No. 2 area, and formed a high-pressure gathering and transportation dehydration process suitable for natural gas with high hydrogen sulfide content in Shunbei No. 2 area, which provides technical support for the further development of Shunbei natural gas blocks.
