Non-point source phosphorus (P) loss from farmland is one of the most serious causes of agricultural non-point source pollution. It is very necessary to identify the critical source areas and influence factors for the risk of P loss from farmland in a watershed, in order to prevent non-point source pollution. The objective of this study was to assess the risk of P loss from farmland in China from 2000 to 2020. P index model was also used. Among them, the soil available P content and fertilizer-P application rate were selected as the source factors. The soil-erosion modulus, annual runoff depth, and the normalized differential distance index between farmland and river network were used as the transport factors. Additionally, the GIS technology was then combined to identify the critical source areas of P loss from farmland. Random Forest (RF) was utilized to derive the critical influencing factors on the P loss from farmland in China. Structural Equation Modeling (SEM) was constructed to explore the relationship between the P index and influencing factors. The results show that: 1) The low, medium, high, and very high-risk areas of P loss from 2000 to 2020 accounted for 43.8%, 40.5%, 13.4%, and 2.4% of the total area of farmland, respectively. 2) The annual average percentage of the total area at high and very high risk of P loss from farmland in 2000, 2005, 2010, 2015, and 2020 was ranked in the descending order: the Huaihe River Basin, Yangtze River Basin, Pearl River Basin, Southeast River Basin, Songhua and Liaohe River Basin, Southwest River Basin, Yellow River Basin, Continental River Basin, and Haihe River Basin. 3) The RF results showed that the available P content and normalized differential distance index were the critical influencing factors of the P index, whose importance eigenvalues were 129.53 and 65.12, respectively. The available P content was the critical influencing factor of the P loss from the farmland. 4) SEM images showed that the P index was extremely significantly positively correlated with the source and transport factor indexes. The P index of the 14 selected index factors amounted to 0.62, in which the contribution rates of the source factor and the migration factor to the P index were 0.77 and 0.19, respectively (P<0.001). In conclusion, the findings can provide scientific references for the evaluation of non-point source pollution in farmland. It is of great significance for the decision-making on the prevention and control of agricultural surface pollution. [ABSTRACT FROM AUTHOR]

A reinforced concrete subsoil granary has been the promising type in agricultural production in recent years. Among them, a steel plate is used as the waterproof layer, which is connected to the reinforced concrete silo wall by welded bolts on the contact side of the steel plate and the reinforced concrete silo wall. The moisture-proof layer is taken as the aerated concrete blocks using epoxy structural adhesive. Specially, the aerated concrete block is bonded to the steel plate, thus forming a structural layer of epoxy structural adhesive bonding the steel plate and aerated concrete block. This study aims to evaluate the safety and reliability of this structural layer under the horizontal lateral pressure and friction of grain. The results are as follows: 1) Once the adhesive area was the same, there was the increase in the deformation, ultimate bearing capacity and bond strength at the interface of steel plate aerated concrete block under horizontal-vertical bidirectional loading, compared with the vertical unidirectional loading. The better bonding performance was then achieved under the horizontal lateral pressure that generated by the grain storage in the silo; 2) The damage pattern of vertical unidirectional loading was obtained, where the aerated concrete blocks were peeled off from the epoxy structural adhesive; In horizontal-vertical bidirectional loading, a penetrating crack was formed in the aerated concrete blocks, and then the whole block moved downward under the horizontal load, but without peeling off. A comparison was made on the damage patterns of vertical unidirectional loading and horizontal-vertical bidirectional loading. Therefore, it was beneficial to the stabilization of the interface, in the case of aerated concrete blocks under vertical loading while applied horizontal lateral pressure. 3) The bond strength was closely related to the friction force on the silo wall, when the adhesive area was A, 0.8A, 0.5A (A was the contact area between a single aerated concrete block and a steel plate). Once the adhesive area was 0.5A, the smallest height of grain storage was achieved under the vertical unidirectional loading, indicating the larger than the actual height. Therefore, the structural layer with the gluing area of 0.5A was fully met the requirements of the bearing capacity and bonding strength under grain storage loads in the design of underground granaries. 4) It was feasible to adopt the construction practice of epoxy structural adhesive bonding steel plates and aerated concrete blocks for underground granaries under the horizontal lateral pressure and vertical friction of grain. 5) The bearing capacity and bond strength were fully met the requirements, when the bonding area of epoxy structural adhesive exceeded 50% of the total area of aerated concrete block. Further consideration should be given to the influence of the epoxy structural adhesive thickness and application mode on the displacement, bearing capacity, bond strength and damage pattern of the structural layer. The findings can provide a strong reference for the safety and reliability of the waterproof and moisture-proof structural layer in the new underground granary. [ABSTRACT FROM AUTHOR]

Objective: To explore the effect and mechanism of Shenfu Injection on heart failure rats based on the PI3K-AKT-mTOR signaling pathway. Methods: Sixty SD rats were randomly divided into a normal control group (n=20）, a heart failure model group (n=20）, and a Shenfu injection treatment group (n=20）. The normal control group did not receive any treatment, while the other two groups were treated with abdominal aortic constriction to construct a heart failure model. The heart failure model group was given sodium chloride solution, and the Shenfu injection treatment group was given Shenfu injection. Compare the cardiac function, oxidative stress, inflammatory factors, and P13K Akt m TOR expression of rats in each group. Results: Compared to the normal control group, the levels of left ventricular end diastolic diameter (LVEDD) and left ventricular end systolic diameter (LVESD) in the Shenfu injection treatment group and heart failure model group increased sequentially, while the levels of left ventricular ejection fraction (LVEF) decreased sequentially (P＜0.05）. Compared to the normal control group, the level of serum malondialdehyde (MDA) in the Shenfu injection treatment group and the heart failure model group increased in turn, and the level of serum superoxide dismutase (SOD) decreased in turn (P＜0.05）. Compared to the normal control group, the Shenfu Injection treatment group and the heart failure model group had serum interleukin-6 (IL-6) and interleukin-1 levels β (IL-1 β）, Tumor Necrosis Factor-α (TNF-α) The levels increased sequentially (P＜0.05）. Compared to the normal control group, the expression of P13K-Akt-mTOR in the Shenfu Injection treatment group and heart failure model group decreased sequentially (P＜0.05）. Conclusion: Shenfu Injection can protect the cardiac function of heart failure rats, alleviate oxidative stress response, and inhibit the expression of inflammatory factors. Its mechanism of action may be related to the activation of the P13K-Akt-mTOR signaling pathway. [ABSTRACT FROM AUTHOR]

Objective: To explore the study of mother group B streptococcus(GBS) colonization causing macrophage cytokine and cellular immune function alterations in newborns. Methods: Forty-three neonates with confirmed maternal GBS colonization admitted to the Second Affiliated Hospital of Guangzhou Medical University from March 2020 to January 2022 were prospectively selected and set as the study group, while forty normal newborns at the same time period were control group. The levels of macrophage-related cytokines and T lymphocyte subsets, and NK cell levels were compared between two groups. The clinical manifestations that appeared in neonates after GBS colonization were analyzed. Results: The levels of CD3+ T, CD19+ T, CD3+ CD8+ T, CD4+ /CD8+ T, and NK cells were higher in study group than control group, and CD3+ CD4+ was lower than control group(P<0.05). The levels of IFN-γ, IL-13, IL-4, IL-10 were higher in the children of study group than control group(P<0.05). The levels of serum macrophage migration inhibitory factor(MIF), CXCL9, CXCL10 and CCL3 were higher in study group than control group(P<0.05). Levels of CD4+ /CD8+ T cells, NK cells, IFN-γ, IL-13, IL-4, IL-10, MIF, CXCL9, CXCL10 and CCL3 were proved to be positively correlated with neonatal GBS infection, and levels of CD3+ CD4+ T cells were negatively correlated with neonatal GBS infection(P<0.05). There were 4 cases of respiratory distress, 1 case of shock, 2 cases of sepsis, 1 case of meningitis and 2 cases of positive gastric fluid culture in study group of neonates. Prognosis and regression: all study groups were discharged cured. Conclusion: Macrophage-associated cytokines and T lymphocyte subpopulation levels are involved in the immune response process of neonatal GBS infection, and macrophage-associated cytokines and altered cellular immune function are associated with neonatal GBS infection. Maternal GBS PCR screening in late pregnancy is beneficial in identifying early-onset GBS infection. [ABSTRACT FROM AUTHOR]

Castor bean root rot is a root disease caused by Fusarium solani, which seriously threatens the production of castor bean. Due to the lack of resistance genes, the breeding for root rot resistance in castor bean is seriously restricted. In order to mine resistant resources and establish resistant molecular markers, the phenotypic and molecular marker identification was performed on the disease resistance of 252 castor bean accessions in this study. The results were as follows: (1) Irrigating roots with the conidia suspension of 1×106 spores·mL-1 was an effective inoculation method. The 5-grade evaluation method based on the days of wilt after inoculation could be used as the criteria to evaluate the resistant level of accessions objectively. (2) According to the criteria, the resistance of 252 accessions were divided into five grades from high to low, among which Grade 1 was high resistance and Grade 2 was moderate resistance. The number of accessions with different grades from 1 to 5 were 105, 25, 33, 31 and 58, respectively, accounting for 42%, 10%, 13%, 12% and 23%, respectively. A total of 130 resistant accessions were identified, of which 105 were high resistance and 25 were moderate resistance. (3) The proportion of resistant accessions in wild accessions (66%) was much higher than that in cultivated accessions (35%) . Among wild accessions from South China, 69% were resistant accessions, and 60% were high resistance accessions. It is strongly suggested that the research and utilization of wild accessions, especially the wild accessions in South China, should be an important direction of resistance breeding in the future. (4) Eight SSR markers associated with the resistance were preliminarily established. Although different resistant accessions carried different markers or marker combinations, most of them carried three to four of the above markers, therefore, they can be used as resistant molecular markers for assisted selection. The results of this study provide an effective method and evaluation criteria for root rot resistance identification, screen out a number of resistance genetic resources urgently needed in breeding, and preliminarily establish the SSR markers available for assisted selection, which lay an important foundation for resistance breeding of castor bean root rot.

OBJECTIVE: To evaluate the efficacy and safety of 5% minoxidil combined with finasteride in the treatment of androgenic alopecia (AGA), so as to provide evidence-based reference for clinical application of 5% minoxidil. METHODS: PubMed, the Cochrane Library, CNKI, VIP, CBM and Wanfang Data were retrieved for randomized controlled trials (RCT) on 5% minodil combined with finasteride in the treatment of AGA published before Jun. 1st, 2022. Literature was screened by title, abstract and full text in turn, and Meta-analysis was performed by using RevMan 5. 4 statistical software. RESULTS: After screening, 7 RCT were included. Results of Meta-analysis showed that after 3, 6 and 12 months of treatment, the efficacy of AGA in the combined treatment group was better than that in the 5% minoxidil group or finasteride group, the differences were statistically significant (P<0. 01). The incidence of adverse drug reactions of topical 5% minoxidil was significantly higher than that of oral finasteride, the difference was statistically significant ( P < 0. 01). CONCLUSIONS: For patients with AGA, topical 5% minoxidil combined with oral finasteride is the most effective. However, local itching, increased dandruff or dermatitis may occur during medication, and attention should be paid to the occurrence of adverse reactions on the skin and its accessories. Adverse drug reactions such as sexual dysfunction may occur and should be given attention, patient’ s liver function should be promptly monitored during drug medication. [ABSTRACT FROM AUTHOR]
