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]

Based on whether the expected output includes agricultural ecosystem services, this paper makes a comparative analysis of agricultural ecological efficiency in Guizhou karst mountain area, in order to provide theoretical reference and data support for promoting the green development of agriculture in this area. The super-efficiency SBM model and GML index were used to measure the two agricultural eco-efficiency of nine cities and prefectures in Guizhou from 2000 to 2019,and the Tobit regression model was used to explore its influencing factors. The results show that: The traditional agro-ecological efficiency is only effective in Guiyang. After considering agro-ecosystem services, the average agricultural efficiency of other cities and states enters the effective zone except Liupanshui, Anshun, Qianxi and Qiannan. During the study period, the traditional agricultural total factor productivity (GML) of Guizhou increased by 2% annually, especially the exponential growth of GML after 2012. In addition to Zunyi, Qiandongnan and Tongren,the traditional agricultural total factor productivity (GML) of the other cities and states was greater than 1,and the improvement of agricultural ecological efficiency in each city and state was mainly driven by technological progress. In addition to Zunyi and Tongren, the improved GML index of other cities and states is lower than the traditional one. Industrial structure, financial support for agriculture, and agricultural mechanization density were positively correlated with both traditional and improved agroecological efficiency; farmers’ income level and fertilizer use intensity were negatively correlated with both traditional and improved agroecological efficiency; per capita cultivated land level and vegetation coverage were positively correlated with improved agroecological efficiency, but negatively correlated with traditional agroecological efficiency.

Lactic acid bacteria (LAB)plays an important role in the intestinal health of animals. In order to screen out excellently properties LAB strains, in this study, LAB from the feces of healthy south China tigers (Panthera tigris amoyensis) were isolated, cultured, purified and identified. The biological characteristics of these strains were evaluated by studying its bacteriostatic properties against Escherichia coli, Staphylococcus aureus, Salmonella sp. and Edwardsiella tarda, acid resistance and bile salts resistance, hemolytic activity and drug against resistance test of 24 kinds of drugs. The results showed that a total of 78 strains of LAB were isolated, among which 15 strains had good antibacterial performance and the antibacterial circles were greater than 15 mm against the four pathogenic bacteria mentioned above, including six strains(22YY08，22DC20，22XX19，22Hui09，22LL14 and 22XX03) of Lactobacillus reuteri, three strains(22HH02，22YY13 and 22YY09)of L. crispatus, two strains(22Hui15 and 22LL07) of Ligilactobacillus animalis, one Pediococcus pentosaceus(22DC18), one Lactobacillus mucosae (22DC10), one L. johnsonii(22DC09), and one Lactococcus garvieae (GaL110). Further, eight LAB strains were screened out and showed good tolerance at pH 2. 5 and bile salt concentration of 0. 1%, and had no hemolytic activity. Among them, three strains of Lactobacillus reuteri(22Hui09，22YY08 and 22LL14) were resistant to multiple drugs while others were susceptible. In conclusion, three strains of L. reuteri(22DC20，22XX03 and 22XX19)，Pediococcus pentosaceus 22DC18, and Lactococcus garvieae GaL110 obtained in this study are promising candidates for the development of probiotic preparations in south China tiger.

BACKGROUND: At present, there are few reports on the application of compressed sensing technology in ankle MRI. OBJECTIVE: To investigate the effect of different acceleration factors in compressed sensing (CS) on image quality and scanning time of conventional 2D-MRI of the ankle joint. METHODS: Totally 24 healthy volunteers (38 ankles) underwent conventional 2D-TSE sequence scanning at 3.0T MR. Based on SENSE parallel imaging (S group) and compressed sensing technique (CS group), sequence images of T1WI-TRA (S1.3, CS1.3, CS1.9, CS2.7), PDWI-Dixon-SAG (S1.8, CS1.8, CS2.6, CS3.2) and PDWI-SPAIR-COR (S1.3, CS1.3, CS1.6, CS2.0) were obtained separately. Other scan parameters of each sequence remained consistent. The tendon, cartilage, ligament and muscle structures of the ankle joint images were subjectively scored by 5 points. The standard deviation of background noise and signal intensity of bone, cartilage, ligament, tendon, muscle, effusion and fat structures were measured, and the signal-to-noise ratio and contrast-to-noise ratio were calculated. The subjective score and objective evaluation of different acceleration factor images were statistically analyzed. SENSE group was used as the standard reference for the image quality of each sequence. RESULTS AND CONCLUSION: (1) When acceleration factor was the same, there were no statistically significant differences in subjective score, signal-to-noise ratio and contrast-to-noise ratio between the S group and the CS group (P > 0.05). (2) The acceleration factor of CS (TRA), CS (SAG) and CS (COR) sequences at CS1.9, CS2.6 and CS1.6 showed no significant difference in the image quality of cartilage, tendon, ligament and other main observed structures of the ankle joint (P > 0.05), and the scanning time was 1 minute and 32 seconds, 1 minute and 42 seconds, 1 minute and 48 seconds, respectively. When the acceleration factor of CS (TRA), CS (SAG) and CS (COR) sequences increased to CS2.7, CS3.2 and CS2.0, respectively, the subjective scores of all anatomical structures were still greater than 3, but signal-to-noise ratio and contrast-to-noise ratio of each sequence decreased significantly (P < 0.05). (3) These findings confirm that when acceleration factor is the same, compared with CS group, the image quality obtained by CS group is generally higher than that of S group. When acceleration factor increases, the scanning time of CS sequence decreases gradually, and the image quality also decreases. On a 3.0T MR, CS technology recommended CS1.9, CS2.6, and CS1.6 accelerators for conventional 2D sequences T1WI-TRA, PDWI-Dixon-SAG, and PDWI-SPAIR-COR, respectively, reducing the overall time by about 27% (1 minute and 53 seconds).

Objective: To investigate the effect of lipopolysaccharide (LPS) of Porphyromonas gingivalis(P. g)on the expression levels of ferroptosis-related factors in the macrophages, and to clarify the influence of ferroptosis-related factors in the pathogenesis of periodontitis. Methods: The mouse mononuclear/macrophage line RAW264. 7 cells were cultured and divided into experimental group and control group. The cells in experimental group were treated with 10 mg·L -1 P. g-LPS for 6, 12, and 24 h, respectively；the cells in control group were not treated. Real-time fluorescence quantitative PCR (RT-qPCR) method was performed to detect the expression levels of long chain acyl-CoA synthetase 4 (ACSL4), glutathione peroxidase 4 (GPX4), and transferrin receptor 1 (TfR1) mRNA in the RAW264. 7 cells in two groups. The levels of reactive oxygen species(ROS)in the RAW264. 7 cells in two groups were detected by 2', 7'-dichlorodihydrofluorescein diacetate(DCFH-DA) fluorescence probe method. The levels of malondialdehyde(MDA)in the RAW264. 7 cells in two groups were detected by thiobarbituric acid (TBA) method and the levels of ferrous ion (Fe2+) in the RAW264. 7 cells in two groups were detected by Ferrousion fluorescent probe (FeRhonox-1) method. The expression levels of ACSL4, GPX4, and TfR1 proteins in the RAW264. 7 cells in two groups were detected by Western blotting method. Results: Compared with control group, the expression levels of GPX4 mRNA in the RAW264. 7 cells in experimental group after treated for 6, 12, and 24 h were decreased(P<0. 05), the expression levels of ACSL4 and TfR1 mRNA in the RAW264. 7 cells in experimental group after treated for 12 and 24 h were increased (P<0. 05)；the expression levels of ACSL4 and TfR1 proteins in the RAW264. 7 cells in experimental group after treated for 12 and 24 h were increased (P<0. 05)；the expression levels of GPX4 protein in the RAW264. 7 cells in experimental group after treated for 12 and 24 h were decreased(P<0. 05). Compared with control group, the levels of ROS, MDA, and Fe2+ in the RAW264. 7 cells in experimental group were significantly increased(P<0. 05), and showed an increasing trend with time prolongation. Conclusion: The expression levels of ferroptosis-related factors ACSL4 and TfR1 are increased and the expression level of GPX4 is decreased in a time-dependent manner induced by P. g-LPS, suggesting that the changes of ferroptosis-related factors may be related to the pathogenesis of periodontitis.
