The ecology of mining areas has been one of the most crucial components in terrestrial ecosystems. However, the over-exploitation of mineral resources has posed a great threaten to the ecosystem in recent years, leading to frequent environmental issues, such as land degradation, vegetation loss, and water scarcity. Therefore, accurate monitoring of mining ecology is of great importance to protect the ecological environment and balance. Remote sensing technology can be expected to provide an effective means for the ecological monitoring in mining areas. In this study, Remote Sensing Ecological Index (RSEI) was improved to realize the overall spatial average on the indicator weights for the ecological monitoring of mining sites. The factor of coal dust pollution was also added into the conventional greenness, wetness, dryness and heatness. The indicator weights were then determined using Geographically Weighted Principal Component Analysis (GWPCA). The indicator was finally selected to construct Geographically Weighted-Remote Sensing Ecological Index (GW-RSEI). Taking the Datong coal field in Shanxi Province as an example, the validity and applicability of GW-RSEI were verified for monitoring mining area ecology using multi-phase remote sensing images from 2000 to 2020. The results showed that the indicator weights of GW-RSEI were varied continuously over the space, indicating the spatial heterogeneity within different local surface areas. GW-RSEI shared the average correlation coefficients with universal normalized vegetation index (UNVI), normalized difference moisture index (NDMI), soil index (SI), temperature vegetation dryness index (TVDI) and index-based coal dust index (ICDI) of 0.76, 0.78, -0.77, -0.82 and -0.41, respectively, (P<0.05). Furthermore, the GW-RSEI was integrated each indicator to fully reflected the ecological environment of mining areas. The overall monitoring that obtained by GW-RSEI was similar to that by RSEI over the past two decades. However, the GW-RSEI was focused on the real ecological impacts at the surface, indicating the more reliable at local scales. Whether in areas with single or complex land use types, GW-RSEI exhibited the higher correlations with soil moisture (SM), net primary productivity (NPP) and particulate matter 2.5 (PM2.5) than RSEI. The GW-RSEI monitoring was more consistent with the actual surface, in order to effectively reflect the ecological environment of the mining areas. Therefore, the GW-RSEI was successfully used to monitor the severe pollution of coal dust in local coal mining activity areas. The grade of GW-RSEI was lower than that of RSEI in the areas with the severe pollution of coal dust. The trend was the gradually increasing from the area with the high level of coal dust pollution as the center to the surrounding areas, indicating the spatial pollution in mining areas. The GW-RSEI values were higher than RSEI ones in urban areas of the county with the medium to high vegetation cover, and in rural areas where the land type was mainly arable land and grassland. There were significantly more medium to low GW-RSEI value in the mining area and surroundings, compared with the RSEI. Furthermore, the gradual trend was highlighted the spatial continuity in ecological environment quality. GW-RSEI averages were 0.51, 0.48, 0.46, 0.59, and 0.56, indicating that the overall ecological environment experienced a process of first deterioration and then improvement. The trend in the southeastern region of Datong Coal field was consistent with the overall trend, while the northwestern region showed a trend of first improvement and then deterioration. The GW-RSEI can provide the more effective way to accurately monitor the ecology of the mining area. [ABSTRACT FROM AUTHOR]

Objective To investigate the weight status of normal single-born live newborns of different gestational ages, obtain the latest birth weight standards of normal newborns of different gestational ages and birth weight standards of male and female newborns of different gestational ages, and draw birth weight curves of newborns. Methods A retrospective analysis was conducted on the birth weight of newborns delivered in the department of Obstetrics of Yunnan First People’s Hospital from January 1, 2014 to December 31, 2020 without complications, severe malformation or edema during live birth. The birth weight curve was fitted by the internationally established LMSP method. The curve was drawn and checked by the Generalized Additive Model based on Position, Scale and Shape (GAMLSS) 5.3-4 software package in R4.0.2 software. Result The percentile values of birth weight P3, P10, P25, P50, P75, P90, P97 and corresponding birth weight curves were obtained from 36 551 cases of newborns born alive at 26 to 42 weeks of normal gestation. There were 19, 072 males (52.18%) and 17, 479 females (47.82%), respectively, with an average birth weight of 3 231 g and 3 128g. The average birth weight of female newborns was 103 g less than that of male newborns, and the difference was statistically significant (P < 0.05). The overall incidence of < gestational age and > gestational age was 8.98% and 9.29%, respectively. Conclusion It is the first time to collect the weight of single live newborn born at 26-42 weeks of normal gestation in Yunnan First People’s Hospital in the past 10 years with large sample size and updated data. The birth curve drawn can accurately and objectively evaluate the current intrauterine growth and development status of fetuses and perinatal outcomes in Yunnan First People’s Hospital. It provides important reference value for perinatal health care in Yunnan First People’s Hospital and even in Kunming area. [ABSTRACT FROM AUTHOR]

In recent years，due to the increase of high-risk pregnancies in obstetrics and the improvement of diagnostic techniques，clinical attention to pregnancy complicated with venous thrombotic diseases is increasing from year to year. Although various risk factors that induce deep vein thrombosis have been identified，the mechanism of thrombosis is not yet completely clear. Studies have demonstrated that histones play a key role in venous thrombotic diseases，mediating the production of thrombus through inflammatory pathways or TLRs that activate inflammation.This article aims to provide an overview of histone-induced venous thrombotic diseases through TLRs to stimulate inflammation，and provide a new breakthrough point for the prevention and treatment of obstetric venous thrombotic diseases in the future.

BACKGROUND: Extraction is commonly used for class II malocclusion to achieve normal cover and improve facial feature and lateral appearance, and the treatment efficacy is directly related to adduction degree of anterior teeth and alveolar bone reconstruction. OBJECTIVE: To investigate the alveolar bone change of the maxillary anterior region after retraction in adult patients with class II1 malocclusion. METHODS: Thirty adult patients with class II1 malocclusion were selected. After aligned and replaced with stainless steel square wire for 1 month (T0 stage), the upper anterior teeth were retracted with type II traction for 1 month (T1 stage). Cone-beam CT was made before and at T0 and T1 stages. The upper anterior teeth volume, alveolar bone thickness and height were measured. RESULTS AND CONCLUSION: (1) After retraction, the crown of the upper middle incisor was moved lager than root in tongue direction. (2) The thickness of the alveolar bone significantly increased in the labial region except the apical region (P < 0.05), and the apical area changed inversely. (3) Both labial and palatal alveolar ridge decreased, and difference on the palatal side was significant (P < 0.05). (4) In summary, for adult patients with class II1, a tipping movement occurred in the process of anterior retraction. During retraction, the alveolar bone changes are not consistent with the movement of the teeth, and active bone remodeling occurred on both labial and palatal sides, but overall, bone resorption is greater than bone hyperplasia.
