Currently, self-propelled trimming machines for tea gardens have problems of low automation level and poor maneuverability. In this work, a contact-style automatic ridge-following navigation system and its corresponding control algorithm for a small-scale, wheeled trimming machine in tea gardens were proposed considering the structural features of tearidge boundaries. A contact-style automatic ridge detection mechanism based on low-cost laser ranging sensors was designed.The working principle of the detection mechanism was introduced and analyzed. The position and heading information of the trimming machine with respect to the tea ridge was derived through the opening and closing of two side baffles of the detection mechanism caused by the changing profiles of the tea ridge boundaries. The navigation system hardware included a power supply unit, remote control unit, sensing unit, steering unit, driving unit, and control unit. The sensing unit consisted of twolow-cost laser ranging sensors for measuring the changing distances of the baffles of the ridge following the detection mechanism and an absolute optical encoder for determining the real-time steering angle of the steering wheel. The steering unit replaced the original manual steering mechanism of the trimming machine with a stepper motor to realize electrical control. By analyzing the four pose states of the trimming machine with respect to the tea ridge, the kinematic navigation model of the trimming machine was derived, and the lateral and heading deviations of the trimming machine with respect to the tea ridge centerline were obtained. A navigation controller was designed based on an LQR (linear quadratic regulator) algorithm derived from the kinematic model of the trimming machine. The position and heading information of the machine were taken as control inputs. After calculation by the control algorithm, proper steering signals were sent to the stepper motor for deviation correction. Tovalidate the feasibility of the contact-style navigation system and evaluate the performance of the control algorithm, field experiments in a tea garden were conducted. The trimming machine was controlled to automatically follow a tea ridge at three different speeds, 0.2, 0.4, and 0.6 m/s. The experiment for each speed was repeated three times. Results showed that under three speeds, the maximum absolute deviation of the trimming machine was no larger than 0.134 m, the absolute deviation maximum was no larger than 0.107 m, and the standard deviation maximum was no larger than 0.105 m. This navigation performance was comparable to mainstream navigation systems developed based on RTKGNSS, vision and laser sensors. The mean absolute deviation and standard deviation increased slightly as the running speed of the trimming machine increased. However, theywere kept in the 0.15 m limit. This indicated that the navigation method based on the contact-style automatic ridge-following mechanism was feasible, and the LQR algorithm derived based on the kinematic model of the trimming machine could meet the accuracy requirement of tea ridge following under a practical tea garden environment. The low-cost, contact-style navigation system and its corresponding algorithm proposed in this work can provide a reference for the development of automatic navigation systems for self-propelled operation machines in tea gardens.

Objective To investigate the regulatory effect of miRNA-933 on the apoptosis and proliferation of human hepatic stellate cell line LX-2 and its mechanism. Methods Firstly, with human liver tissue for research, gene micmarray technology was used to detect the differentially espressed genes in liver tissue between liver cirrhosis/chronic hepatitis B tissue and normal liver tissue, among which the significantly differentially expressed miRNAs were identified, and thus miltNA-933 was determined as the research object. Then, with the human hepatic stellate cell line LX-2 for research, miRNA-933 mimic and inhibitor (miRNA-933 siRNA) were used to construct the LX-2 models of overexpression and knockdown, and the cells transfected with mimic-NC (overexpression) or siRNA-NC (knockdown) were established as the negative control group. Quantitative real-time PCR and Western blot were used to measure the expression levels of miRNA-933 and activation biomarkers; techniques such as cell proliferation assay and flow cytometry were used to investigate the effect and mechanism of miRNA-933 on cell apoptosis. proliferation, and activation. The independent-samples i test was used for comparison of contimaous data between two groups; a une way analysis of variance was used for comparison between multiple groups, and Bonferroni correction was also performed. Results A total of 18 significantly differentially expressed miRNAs were obtained based on the results of gene microarray, among which miRNA-933 was significantly downregulated (P<0.05). After LX-2 cells were transfected with miRNA-933 mimiy or siRNA. compared with the negative conttul group, milINA-933 siRNA significantly downregulated the expression of miRNA-933 (P=0.0007), while miRNA-933 mimic significantly upergulated the expression of miRNA-933 (P=0.000 3). Western blot and quantitative real- time PCR showed that miRNA-933 siRNA significantly upregulated the expression of collagen 1 and a SMA (P<0.001), while miRNA-933 mimic significantly inhibited the expression of collagen 1 and -SMA (P<0.05). Flow cytometry showed that compared with the negative control group, miRNA-933 siRNA significantly downregulated the apoptosis rate of LX-2 cells (P=0.031 9), and miRNA-933 mimic significantly upregulated the apoptosis rate of LX-2 cells (P=0.005.5), Western blot showed that compared with the negative control group, miRNA-933 siRNA could inhibit the expression of Caspase-3 (-0.006 7) and poly (ADP-ribuse) polymerase-1 (PARP-1) (P=0.0030) and upregulate the expression of B-cell lymphoma-2 (Bel-2) in LX-2 cells (P=0.0020), while miRNA-933 mimie could significantly upregulate the expression of Caspase-3 (P=0.0118) and PARP-1 (P=0.049 5) and downregulated the expression of Bel-2 (P=0.002 1). Cell proliferation assay showed that compared with the negative control group. miRNA-933 siRNA could promote the proliferation of LX-2 cells (P=0.0115), while on the contrary, miRNA-933 minic could inhibit the proliferation of LX-2 cells (P=0.001 2). Western blot and quantitative real-time PCR showed that miRNA-933 IRNA significantly inhibited the expression of Kruppel-like factor 6 (KLF6) and downregulated the expression of activating transcription factor 4 (ATF4), activating transcription factor 3 (ATF3), and C/ERP homologous protein (CHOP), while miRNA-933 mimie promoted the experssion of the above proteins (all P<0.05). Conclusion This study shows that miRNA-933 may promote cell apoptosis and inhibit cell activation and proliferation by promoting the activation of the KLF6/ATF4/ATF3/CHOP/Bel-2 signal axis in LX-2 cella, [ABSTRACT FROM AUTHOR]

As the material basis for the survival of life, fresh water resources are facing serious challenges. Using efficient solar-driven interface evaporation (SSG) is an important means to solve the current water shortage. A new porous material conjugated microporous polymer (CMPs) plays an important role in water treatment technology. A new type of solar energy evaporator (CMC/SCMP-PPY) was prepared by spraying polypyrrole on its surface with CMCZ SC MIy as a precursor. The light absorption rate was up to 91 % and the photothermal conversion ability was realized. The aerogel showed good photothermal conversion performance under 1 kW/mJ irradiation, and the evaporation efficiency reached 85.57%. The porous structure and hydrophilic characteristics make it have excellent water transport ability, and the stable chemical structure makes it have excellent salt resistance to prevent salt crystal deposition and clogging material channels, so that it can realize the photothermal conversion ability. This work further optimizes the purification of CMPs in wastewater, realizes the utilization of clean energy, and provides a new idea for the development of new photothermal materials.

To explore the relationship between fertility index (EFI) score, serum macrophage migration inhibitory factor (MMIF), Chitin enzyme protein 40 (YKL-40), ovarian function and clinical stage of patients with Endometriosis. Eighty patients with Endometriosis admitted to our hospital from June 2020 to June 2023 were selected as the study subjects, and they were dividedinto an observation group. Eighty healthy female volunteers who came to our hospital for physical examination at the same time were selected as the control group. The EFI score, serum MMIF, YKL-40 and the expression level of ovarian function indicators of the twogroups were compared. Eighty patients with Endometriosis were classified according to the American Association of ReproductiveMedicine Endometriosis staging criteria (r-AFS), including 15 patients with stage I, 23 patients with stage II, 25 patients with stage III, and 17 patients with stage IV. The EFI scores, serum MMIF, and YKL-40 expression levels in patients with different r-AFS stages were compared. And the Spearman correlation analysis method was used to analyze the correlation between EFI score, serum MMIF, YKL-40, and ovarian function indicators. The EFI score of the observation group was lower than that of the control group, and the expression levels of serum MMIF and YKL-40 were higher than those of the control group (P<0.05); The expression levels of anti M俟llerianhormone (AMH), Luteinizing hormone (LH) and follicle stimulating hormone (FSH) in the observation group were lower than those in the control group, and the level of estradiol (E2 ) was higher than that in the control group (P<0.05); The EFI scores of patients with Endometriosis in different stages from high to low were stage I, stage II, stage III, and stage IV, and the levels of MMIF and YKL-40 from high to low were stage IV, stage III, stage II, and stage I. The EFI scores, serum MMIF, and YKL-40 expression levels in different stages were significantly different (P<0.05); The Spearman correlation analysis showed that the EFI score was positively correlated with AMH, LH, FSH, and negatively correlated with E2 (P<0.05). MMIF and YKL-40 were negatively correlated with AMH, LH, FSH, and positively correlated with E2 (P<0.05). EFI score, serum MMIF, and YKL-40 levels are significantly correlated with the ovary of Endometriosis patients, and there are significant differences between the EFI score, serum MMIF, and YKL-40 levels of different Endometriosis patients. Clinical application of EFI score, serum MMIF, and YKL-40 levels can be considered to assist in judging the ovarian function and disease severity of Endometriosis patients. [ABSTRACT FROM AUTHOR]

To investigate the effects of ecological planting of an economic forest on the soil bacterial community in a rocky desert area, two natural restoration plots (shrub and arbor shrub) and two ecological planting plots (kiwifruit and walnut) were selected. Soil bacterial community structure and diversity experiments were conducted in a rocky desert area of southeast Yunnan Province. The results showed that the richness and diversity of soil bacterial communities in shurb and arbor shurb natural restoration lands were lower than those in kiwifruit and walnut planted restoration lands. Proteobacteria, Actinobacteriota, Acidobacteriota, and Chloroflexi were the most abundant phyla in soil bacterial communities in shurb natural restoration land,kiwifruit and walnut planted restoration lands, while Proteobacteria, Actinobacteriota, Acidobacteriota, and Bacteroidetes were the most abundant phyla in arbor shurb natural restoration land. Acidibacter spp. were the main active bacteria in arbor shurb natural restoration land. The main active species in shurb natural restoration land belonged to Actinobacteriota and Thermoleophilia. The main bacterial species in kiwifruit and walnut planted restoration land belonged to the Gemmatimonadetes and Chloroflexia, respectively. Correlation analysis of soil bacteria and environmental factors under different restoration plots showed that soil total potassium and available potassium concentrations decreased with the change in vegetation from kiwifruit and walnut planted restoration land to shurb and arbor shurb natural restoration land kiwifruit and walnut to shrub and arbor shrub. In contrast, the soil N, P, and organic matter content and pH value showed a weak recovery trend after natural recovery. [ABSTRACT FROM AUTHOR]

Objective To investigate the correlation between serum levels of small dense low density lipoprotein-cholesterol （sdLDL-C） and chemokine CXC motifligand12（CXCL12） and diabetes mellitus with car⁃ diovascular disease（CVD). Methods A total of 256 diabetic patients treated in our hospital between June 2021 and September 2022 were selected as the diabetic group. The patients were grouped according to whether they had combined CVD or not. And the serum sdLDL-C as well as CXCL12 levels of each group were compared with healthy volunteers. Risk factors for the complication of CVD in diabetic patients were analyzed. To analyze the diag⁃ nostic value of sdLDL-C, CXCL12 and combined test for diabetic patients with complicated CVD. Results Serum sdLDL-C and CXCL12 levels were higher in the diabetes group than in the control group （P < 0.05). The duration of disease, BMI, LDL-C, and serum sdLDL-C and CXCL12 levels were higher in the cardiovascular disease group than in the non-cardiovascular disease group （P < 0.05). A multifactorial logistic regression analysis showed that sdLDL-C and CXCL12 were independent risk factors for the complication of CVD in diabetic patients （P < 0.05). The sensitivity and specificity of serum sdLDL-C and CXCL12 combined test were higher than that of single test. Conclusion Elevated serum sdLDL-C and CXCL12 levels in patients with diabetes mellitus are independent risk factors for the complication of CVD, and the combination of these two tests has a high diagnostic value for diabetes mellitus with CVD.

The current harvesting of edible sunflowers can be discrete two-stage mode, including manual picking for the insert trays to dry for 7 to 10 days, and then machine picking, threshing and cleaning. Edible sunflower combine harvesting equipment is still lacking in adaptability, low cleaning loss, and impurity rate in the field, due to that mostly modified from wheat, and corn harvesters. Cleaning is one of the key steps in the mechanized harvesting of edible sunflower, which is directly related to the rate of impurity and loss of sunflower seeds. Sunflower cleaning device has been focused mainly on theoretical analysis and parameter optimization in recent years. However, only a single-hole sieve has been used to explore the seeds passing-through performance of various edible sunflowers, leading to a high impurity rate and large cleaning loss. It is a high demand for the low-loss and high-efficiency edible sunflower cleaning device, in order to promote the high mechanization level of edible sunflower harvesting. In this study, a new cleaning device was designed with the double-layer vibrating air-sieve for the edible sunflower, particularly for the low loss rate and impurity rate during mechanized harvesting. The device consisted of the fan, upper sieve body with guide tooth plate, lower sieve body of step shaking plate, and the drive mechanism of offset crank slider. The structural parameters of the edible sunflower cleaning device were then determined, where the sieve length was 1 600 mm, the width was 900 mm, and the clearance of the upper and lower sieve was 120 mm. Mechanical design was also carried out to obtain the crank length of 32.5 mm, the slider stroke of 70 mm, and the slideway inclination of 23°. Two groups were determined by the upper and lower woven sieves with square hole diameters of 20, 18 mm, and 18, 16 mm, respectively. Two varieties of edible sunflower were selected as the ‘Sanrui No.10’ and ‘Sunflower 363’ with the threshing mixture of different seed sizes. The movement process of material on the sieve surface was analyzed to obtain the optimal working conditions and the influencing factors on the cleaning performance. The kinematics of the sunflower on the sieve was also explored to obtain the properties of seeds passing through the sieve using the Fluent-EDEM platform. The simulation results showed that the cleaning device with a vibrating air was successfully realized the cleaning work of sunflower seeds, indicating a reasonable structural design. Orthogonal tests were carried out on the self-developed shelf of the cleaning device, where the influence factors were the crank speed, airflow direction angle, and sieve inclination, whereas, the test indexes were the impurity rate and loss rate. The primary and secondary influencing factors were ranked in descending order of the crank speed, sieve inclination, and airflow direction angle. The optimal combination of parameters was the crank speed of 250 r/min, sieve inclination of 4°, and airflow direction angle of 21°. The optimization of parameter combination was repeated five times on the bench for validation tests. The results showed that the impurity rate of both varieties of edible sunflower was less than 3%, and the loss rate was less than 2%, fully meeting the standard for the mechanized harvesting of edible sunflower. The performance of the cleaning device was also better than before. This finding can provide theoretical support for the improvement and optimization of the cleaning system during mechanized harvesting of edible sunflowers. [ABSTRACT FROM AUTHOR]

The aim of the experiment was to investigate the effect of dietary protein level on growth performance, serum immune indexes, antioxidant indexes, rumen fermentation parameters and microflora composition of Angus calves after weaning. Eighteen weaned calves at 90 days of age with good health and similar body weight were randomly divided into three groups (half male and half female) with six replicates per group and one cow per replicate. Calves in experimental groups were fed diets with high protein (19.65% protein, 5.74 MJ/kg net energy, T group), medium protein (18.60% protein, 5.62 MJ/kg net energy, S group) and low protein (17.76% protein, 5.40 MJ/kg net energy, F group), respectively. The experiment lasted for 100 d. The results showed that high protein level diet significantly increased body weight and average daily gain of calves at 120 days of age and 180 days of age ( P<0.05). Compared with S group, the content of IgA and IgM, the activity of SOD and T-AOC in serum of calves in T group were significantly increased ( P<0.05), and the content of TNF- α was significantly decreased ( P<0.05). The content of acetic acid, propionic acid, isobutyric acid and valeric acid in the rumen of T group were increased ( P<0.05). The rumen bacterial diversity index of T group was significantly increased ( P<0.05), and Firmicutes and Bacteroidetes were the dominant bacterial groups. The study indicates that high protein level diet can significantly promote the growth performance and rumen fermentation function of calves, and is beneficial to rumen development of calves.

OBJECTIVE: To systematically review the efficacy of Songling Xuemaikang capsules in the treatment of hypertension and hyperlipidemia by methodological quality assessment tools including AMSTAR 2 scale and grading system of evidence evaluation ( GRADE). METHODS: Systematic reviews of studies with Songling Xuemaikang capsules were enrolled by retrieving databases including CNKI, CBM, Wanfang Data, VIP, the Cochrane Library, PubMed, Web of Science and Springer from base-building to Jul. 27th, 2022. The research results of systematic review were collated and summarized, the quality of each outcome index was evaluated by using the GRADE system, and the quality of enrolled literature was evaluated by using the AMSTAR 2 scale. RESULTS: Finally 9 systematic reviews were enrolled, 8 of which were on the treatment of hypertension with Songling Xuemaikang capsules and 1 on hyperlipidemia with Songling Xuemaikang capsules. The research results of systematic review indicated that compared with pharmaceutical chemicals alone, the efficacy of Songling Xuemaikang capsules combined with pharmaceutical chemicals was better, mainly in terms of indicators such as the total effective rate, systolic blood pressure, diastolic blood pressure, total cholesterol, triacylglycerol, low density lipoprotein cholesterol and low density lipoprotein cholesterol. The results of the GRADE evaluation showed that 9 were moderate evidence, 23 were low evidence and 2 were very low evidence. The results of AMSTAR 2 scale evaluation showed that the methodological quality of all 9 studies was extremely low. CONCLUSIONS: Songling Xuemaikang capsules have a certain efficacy in the treatment of hypertension and hyperlipidemia, but the original literature is of low quality. It is recommended that high-quality clinical randomized controlled trials be conducted to evaluate the safety, efficacy and economical efficiency of Songling Xuemaikang capsules with reference to the evaluation methods of evidence-based medical guidelines, so as to provide higher-quality evidence for clinical purposes.

Macrophages are the second most abundant lymphocyte in the maternal uterine decidua during pregnancy, which can secrete a variety of cytokines and chemokines with anti-inflammatory and pro-inflammatory effects. In addition to participating in decidual immunity as the main antigen presenting cells, macrophages play a key role in the establishment and maintenance of immune tolerance at the maternal-fetal interface, trophoblast invasion, angiogenesis, spiral artery remodeling and phagocytosis of apoptotic cells. Thus, abnormalities in cell number, polarization and function of macrophages are believed to be closely associated with pregnancy complications such as abortion, pre-eclampsia and preterm birth. In order to providing new insights into the pathogenesis of pathological pregnancy from the perspective of immunity and developing precise prevention and treatment strategies, this review focuses on the latest research achievements of the polarization and function of uterine macrophages and their mechanisms in the establishment and maintenance of normal pregnancy and pathological pregnancy in recent years.

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility. Ovulation induction is the first choice of treatment for PCOS patients with fertility requirements. According to the current domestic and international treatment guidelines, clomiphene citrate (CC) is the traditional first-line drug to induce ovulation for infertile women with PCOS. However, the response of CC ovulation treatment varies significantly for different patients. It was reported that about 40% of PCOS patients cannot respond to CC, that is, CC resistance. This paper provides a review on the research progress of predictive indicators for PCOS infertile women with CC resistance as well as alternative ovulation induction strategies in recent years. This paper mainly expounds the predictive indicators for PCOS patients with CC resistance from the perspective of phenotype, biochemical characteristics and genetics. Single or combined schemes are selected in the treatment methods of letrozole (LE), gonadotropin (Gn), laparoscopic ovarian perforation (LOD), in vitro fertilization (IVF) and adjunctive therapy of traditional Chinese medicine to elaborate their alternative ovulation induction strategies, and the advantages and potential shortcomings of these single and combined schemes are discussed to provide more accurate and individualized ovulation induction schemes for PCOS infertile women.
