Objective To analyze the epidemiological characteristics of perinatal birth defects in Henan Province from 2011 to 2020 and to provide basis for the prevention of birth defects. Methods Perinatal birth defect surveillance data from 37 national monitoring sites in Henan Province were collected for newborns delivered from 2011 to 2020. Joinpoint regression was used to describe the trends in birth defect incidence, and Chi-square tests compared incidence rates among different groups (including region, infant sex, and maternal age). Results A total of 29 418 cases of birth defects were monitored in Henan Province from 2011 to 2020, resulting in a total incidence rate of 216.81 per 10 000 births. The annual incidence showed a significant upward trend (AAPC=20.07%, P < 0.001). Incidence rates were significantly higher in urban areas compared to rural areas, in boys compared to girls, and in mothers aged ≥ 35 years compared to those < 35 years (χ²=5 545.926, 257.052, and 403.326 respectively, all P < 0.001). The top 10 birth defects were congenital heart disease (118.47 per 10 000), other malformations (47.62 per 10 000), polydactyly (14.34 per 10 000), cleft lip and palate (10.23 per 10 000), other malformations of the external ear (9.74 per 10 000), syndactyly (5.73 per 10 000), congenital hydrocephalus (5.32 per 10 000), hypospadias (5.24 per 10 000), equinovarus (4.35 per 10 000), and limb shortening (2.69 per 10 000). Conclusion The incidence of birth defects in Henan Province demonstrated a significant upward trend from 2011 to 2020. Comprehensive measures for birth defect prevention and treatment are essential to reduce incidence rates and enhance the quality of the population. [ABSTRACT FROM AUTHOR]

In view of the defect that the vibration signal collected by a single sensor is difficult to accurately describe the dynamic characteristics of rotating machinery, which lead to the inability to accurately identify the fault characteristics of rotating machinery. A fault diagnosis method for rotating machinery based on composite multivariate multiscale fluctuation dispersion entropy (CMMFDE), multi-sensor information fusion and Harris hawk algorithm optimized extreme learning machine ( HHO-ELM) was proposed. Firstly, the composite multivariate coarse-grained processing was introduced and the CMMFDE method was proposed, the defect of traditional univariate analysis methods was avoided, it could only handle single channel vibration signals, resulting in insufficient feature characterization performance, and the representation performance of fault features was enhanced. Then, sensors arranged in different parts of the rotating machinery were used to collect various types of signals to compose mixed multi-channel signals, and CMMFDE analysis was carried out to construct fault characteristics. Finally, HHO was used to optimize the parameters of the extreme learning machine, and the feature samples were trained and tested to complete the fault identification of the rotating machine. Two typical rotating machinery data sets of gear box and centrifugal pump were used for experimental analysis. The research results show that the accuracy obtained when analyzing signals from multiple channels reaches 100% and 98%, which is superior to the accuracy obtained when analyzing single channel signals. At the same time, the recognition accuracy and feature extraction time of the CMMFDE method are superior to the refined composite multivariate multiscale sample entropy (RCMMSE), refined composite multivariate multiscale fuzzy entropy (RCMMFE), refined composite multivariate multiscale permutation entropy (RCMMPE), and multivariate multiscale fluctuation dispersion entropy (MMFDE).

Life conditions and habitat status of mammals could be reflected by trace elements and heavy metals in animal hair which is also a key biological-chemical indicator. To explore the feasibility of monitoring the habitat environment through the content of trace elements and heavy metals in hair of Père David's deer (Elaphurus davidianus), we studied 34 trace elements and 10 heavy metals in hair of Père David's deer from Beijing Milu Park (BMP) and Lin'an City of Zhejiang Province (LAZJ). The results showed that except Re, the other 43 elements were detected in the hair of Père David’s deer. 34 elements were the characteristic elements such as Li, Be, Sc, V, Co, Ga, Rb, Ir, Mo, Cd, Cs, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Tl, Bi, Th, U, Nb, Ta, Zr and Hf. Concentration of six trace elements includ⁃ ing Sr, In, Sb, W, Bi, U and five heavy metals including Zn, Cu, Cr, Pb, Cd in hair of LAZJ were lower than those in BMP, concentration of the other 32 trace elements in LAZJ were higher than those in BMP. Independent sample t-test showed that among the 43 elements, only six elements including Cr (p=0. 064), Ni (p=0. 769), Mo (p=0. 129), Tl (p= 0. 065), Zr (p=0. 138) and Hf (p=0. 057) did not differ significantly between BMP and LAZJ, thereby regional difference existed in hair of Père David's deer. Habitats and food resources of Père David’s deer in BMP and LAZJ were not affected by Zn, Cu, Cr, Pb, Cd, V, Co, Ni, Sb and Tl heavy metals pollution. It is concluded that the content of trace elements and heavy metals in hair of Père David’s deer can serve as non-invasive indicator materials for heavy metal pollution in their habitat.

【Objective】Investigate the effects of different tillage methods on soil moisture,heat dynamics as well as maize dry matter accumulation and yield,to provide theoretical support for maize production in dry farming regions of Inner Mongolia.【Methods】Using random block design,four tillage methods were set up,including conventional ridge cropping (CP),straw off-field no-tillage (NT),straw mulching no-tillage (RNT),and straw mulching strip tillage (RST). Throughout the maize growth stages in 2021—2022,the soil temperature,soil moisture content and maize dry matter accumulation were monitored and measured. Yield was determined at harvest.【Results】Compared with CP,NT,RNT and RST reduced the average soil temperature and 0-5 cm soil active accumulated temperature in the maize growth stages. The 0-5 cm average soil active accumulated temperature of NT and RNT significantly decreased by 69.81 and 127.52 ℃ (P<0.05),respectively in the two years,while RST only decreased by 18.94 ℃ with no significant difference (P>0.05). RNT and RST significantly increased soil water content during the maize growth period,with RNT increasing 107.75 and 74.14 mm and RST increasing 71.50 and 37.89 mm compared to CP and NT,respectively. RST increased maize emergence by an average of 1.58%,9.28% and 9.11% compared to NT,CP and RNT respectively. Both dry matter accumulation and yield at maize maturity stage were RST>NT>CP>RNT in the two years. In comparison to CP,NT and RNT,the dry matter accumulation in RST increasing by 11.68%,4.47% and 12.69%,yield increased by 6.06%,4.22% and 7.21%,and water use efficiency (WUE) increased by 7.63%,5.61% and 6.52%,respectively.【Conclusion】Straw mulching strip tillage had better effect in temperature increasing and soil moisture preserving,significantly increased maize dry matter accumulation and yield,was one of the tillage methods to increase maize yield and efficiency in dry farming regions of Inner Mongolia.

Objective: To explore the mechanism of ropivacaine promoting apoptosis of hepatoma carcinoma cell based on mitochondrial dysfunction and caspase-3 signaling pathway. Methods: Human hepatoma carcinoma cell line BEL-7402 was used for experimental study. After Bel-7402 cells were treated with different concentrations of ropivacaine, the proliferation of hepatoma carcinoma cell was detected by MTT method, the cell morphology was observed by light microscopy and DAPI solution staining, the cell viability was determined by trypan blue staining, the apoptosis of Bel-7402 cells was analyzed by flow cytometry, and the mitochondria were observed under electron microscopy. The nuclear migration of caspase-3 in Bel-7402 cells was observed by laser confocal microscopy, and the effects of ropivacaine on the expression of cytoplasmic apoptosis-related proteins, mitochondrial apoptosis-related proteins, Bel-7402 cells and mitochondrial apoptosis-related proteins were evaluated by western blot assay. Results: Ropivacaine can inhibit the growth of hepatoma carcinoma cell in a dose-dependent and time-dependent manner. The apoptosis of Bel-7402 cells was induced by ropivacaine, and the apoptosis rate of Bel-7402 cells was significantly increased. Ropivacaine can injure mitochondrial function of hepatoma carcinoma cells. Laser confocal microscopy showed the migration of caspase-3 molecules to the nucleus. Ropivacaine interacts with caspase-3 to promote the migration of caspase-3 into the nucleus, stimulate the expression of caspase-3, PARP-1 and caspase-9 proteins, inhibit the expression of Bcl-2, promote the expression of APAF-1, promote mitochondria to release Cytochrome C and activate caspase-3 activity. Conclusion: Ropivacaine can promote the apoptosis of hepatoma carcinoma cell, and its mechanism may be related to the destruction of mitochondrial function and activation of caspase-3 signaling pathway.
