In order to explore the protective effect of metformin mediated nuclear factor-κB (NF-κB) signaling pathway on the damage of diabetic nephropathy cells, HGPC cells were cultured in vitro and treated with 10, 20, 30 and 40 mmol/L D-glucose to select the optimal concentration of D-glucose for the construction of HGPC hyperglycemic inflammatory injury model. Then 20, 40, 80 and 160 mmol/L metformin were used for intervention, and the optimal concentration of metformin was screened. The cells were then divided into control group (Con group), high glucose group (HG group) and metformin group (Met group, 30 mmol/L D-glucose+80 mmol/L metformin), inhibitor group (Y group, 30 mmol/L D-glucose+1 μmol/L NF-κB pathway inhibitor BAY 11-7082), metformin+inhibitor group (Met+Y group, 30 mmol/L D-glucose+80 mmol/L metformin+1 μmol/L BAY 11-7082) and metformin+agonist groups (Met+A group, 30 mmol/L D-glucose+80 mmol/L metformin+1 μmol/L NF-κB pathway agonist Prostratin), intervention was conducted for 24 h. Cell count kit 8 (CCK-8) was used to detect cell viability; the expression levels of inflammatory cytokines were detected by enzyme-linked immunosorbent assay (ELISA); cell invasion and migration were determined by Transwell assay. Western blotting (WB) was used to detect the expression levels of E-cadherin, N-cadherin, vimentin, Fibronectin (FN), NF-κB p65 and p-NF-κB p65. The results show that: HGPC cells were treated with 30 mmol/L D-glucose for 24 h to construct HGPC hyperglycemic inflammation model, and 80 mmol/L was the optimal concentration of metformin. Compared with Con group, the levels of inflammatory cytokines tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), invasion ability, migration ability, the expression levels of N-cadherin, vimentin, FN and p-NF-κB p65 protein in HG group significantly increased, while the expression level of E-cadherin protein decreased (P<0.05). Compared with HG group, the levels of inflammatory cytokines TNF-α, IL-1β, cell invasion ability, migration ability, the expression levels of N-cadherin, vimentin, FN and p-NF-κB p65 protein in Met group and Y group significantly decreased, and the expression level of E-cadherin protein increased (P<0.05). Compared with the Met group, the above indexes changed more significantly after the addition of BAY 11-7082 (P<0.05), and the trend of Met+A group was opposite to that of Met+Y group (P<0.05). Metformin inhibits D-glucose-induced HGPC inflammatory response, invasion, migration and epithelial-mesenchymal transition process by blocking the activation of NF-κB pathway, and protects podocyte injury induced by high glucose.

Objective To explore effects of MCF-7 breast cancer cell conditioned medium on proliferation, apoptosis and migration of bone marrow mesenchymal stem cells (BMSC) and its molecular mechanism. Methods BMSC cultured under normal environment was used as the control group. BMSC cultured with MCF-7 cell conditioned medium was selected as the MCF-7 conditioned medium group. The MCF-7 conditioned medium group supplemented with 10 nmol/L GSK690693 (Akt inhibitor) was used as the Akt inhibitor group. The MCF-7 conditioned medium group added with 10 µmol/L Reparixin (CXCR1/2 inhibitor) was used as the CXCR1/2 inhibitor group. BMSC proliferation was detected by MTT assay. Annexin V-FITC/PI double labeled flow cytometry was used to detect BMSC apoptosis rate in each group. Transwell cell migration assay was used to detect the migration ability of BMSC in each group. The contents of interleukin (IL)-8 protein in two kinds of cell culture supernatant and MCF-7 cell conditioned medium were detected by enzyme-linked immunosorbent assay. The protein expression levels of protein kinase B (Akt)/phosphorylated Akt (p-Akt) and mammalian target of rapamycin (mTOR)/phosphorylated mTOR (p-mTOR) in BMSC of each group were detected by Western blot assay. Results Compared with the control group, cell proliferation level, migration number and the relative expression levels of p-Akt, p-mTOR protein of BMSC were increased in the MCF-7 conditioned medium group, and the apoptosis rate was decreased (P＜0.05). Compared with the MCF-7 conditioned medium group, cell proliferation level, migration number and the relative expression levels of p-Akt, p-mTOR protein of BMSC were decreased in the CXCR1/2 inhibitor group and the Akt inhibitor group, and the apoptosis rate was increased (P＜0.05). The contents of IL-8 protein in MCF-7 cell conditioned medium and MCF-7 culture supernatant were higher than that in the BMSC culture supernatant (P＜0.05). Conclusion MCF-7 cell conditioned medium promotes BMSC proliferation and migration and inhibits BMSC apoptosis by activating Akt-mTOR signaling pathway, in which IL-8-CXCR1/2 axis plays a key role.

Objective To understand the satisfaction of diabetic patients to family doctor contract services and its influencing factors, and to provide evidence for further improving the contract services of family doctors for diabetic patients. Methods From August to September 2019, a total of 514 diabetic patients who had been contracted by their family doctors were investigated using a multi 一 stage stratified random sampling method in three cities of Shandong province. Descriptive analysis, chi 一 squared test and logistic regression analysis were used to study the degree of satisfaction with contracted services and its influencing factors. Results 71. 8% diabetic patients were satisfied with family doctor contract services. Age =7. 025, P =0. 030), familiarity with family doctor = 13. 227, P <0. 001), change of life habit 仗？ = 15. 217, P < 0. 001), change of medical cost =4. 904, P = 0. 027), changes in convenience of medical treatment (2 = 16. 578, P <0. 001), change of waiting time (y2 = 9. 155, P 二 0. 002), and other factors will affect the satisfaction of diabetes patients with the services signed by family doctors. Multivariate logistic regression results showed that diabetes patients with higher annual family income (OR = 2. 321, 95% CI: 1. 298 -4. 148), knew their family doctorJ s name (OR = 1. 804, 95% CI: 1. 041 - 3. 126), believed that their living habits improved after signing the contract (OR = 1. 903, 95% CI: 1. 081 - 3. 350), and had more convenient medical consultation (OR = 1.741, 95% CI: 1. 037 - 2.920) were more satisfied with the service of signing the contract Conclusion The overall satisfaction of diabetic patients to family doctor contract services in Shandong province is relatively high, but there is still room for further improvement. It is suggested that measures should be taken to optimize the contracting services for low 一 income and elderly diabetic patients, and the contact between family doctors and patients should be further strengthened. Emphasis should be placed on guiding patients to form healthy behaviour, and improving the convenience of healthcare in order to improve patients' satisfaction. [ABSTRACT FROM AUTHOR]

Objective To explore the longitudinal bidirectional relationship between depressive symptoms and HIV infection risk behaviors among young men who have sex with men (YMSM). Methods A longitudinal study design was used to recruit 489 YMSM from September 2017 to January 2018 (Tl), and two follow 一 up surveys were completed from July to September 2018 (T2) and from June to July 2019 (T3), respectively. The cross - lagged path analysis model was used to analyze the causality, time series relationship and interactive direction between depressive symptoms and HIV infection risk behaviors. Results Data of 347 YMSM were analyzed using cross 一 lagged path analysis. The results showed that Tl depressive symptoms significantly and positively predicted T2 HIV infection risk behaviors (仔=0.071, 95% CI: 0. 000 - 0. 142), and T2 depressive symptoms significantly and positively predicted T3 HIV infection risk behaviors (仔=0.072, 95% CI: 0. 000 一 0. 143). However, Tl HIV infection risk behaviors did not significantly predict T2 depressive symptoms and T2 HIV infection risk behaviors did not significantly predict T3 depressive symptoms. Conclusion Depressive symptoms among YMSM significantly and positively predicted HIV infection risk behaviors, with a unidirectional causal temporal relationship. Therefore, the level of depressive symptoms should be considered as an essential factor in HIV infection risk behavior interventions for YMSM. [ABSTRACT FROM AUTHOR]

The northern agro-pastoral ecotone is an important ecological security barrier to curb desertification and sandification east to South in China,which is of great strategic significance to national food security and border stability. For a long time,the problems of farmland desertification degradation and productivity decline caused by serious soil wind erosion and over-cultivation have become increasingly prominent. The technology of straw crushing and covering surface wind erosion prevention has been carried out at home and abroad. The application of straw in the agro-pastoral ecotone is easy to blow away the soil and the stability of wind erosion control is poor. Therefore,the in-depth study of straw mulching technology for wind erosion prevention is of great significance in farmland ecological management. The paper discusses straw mulching techniques such as stubble mulching,broken straw mulching and stubble-straw composite mulching on wind erosion prevention and soil moisture conservation and fertilization,elucidates the effects of straw mulching on soil microbial community structure and crop agronomic traits and yield traits,summarizes the innovative content and application effects of stubble-straw composite mulching technology,and clarifies the effect and suitability of the wind erosion prevention by the differentiated stubble-straw composite precision mulching technology created in combination with the ecological characteristics of agro-pastoral ecotone and complex farming systems.The differentiated stubble-straw composite precise mulching technology has become the leading technology in major projects such as black soil protection in Northeast China,national farmland protection and quality improvement,and has been widely promoted and applied,providing important scientific and technological support for farmland protection and utilization,and national food security.

In order to address the current issues of insufficient extraction of deep load features, low decomposition accuracy, and high training costs in the load decomposition model, a multi-scale feature fusion model was proposed. The model was composed of two parts: the load decomposition subnetwork and the load recognition subnetwork, both of which were employed with convolutional blocks composed of one-dimensional convolution and batch normalization for the initial extraction of load features. Subsequently, a pyramid pooling module was incorporated to precisely extract deep load features from multiple dimensions and fused them with the initial feature extraction part. Network parameters and training costs were significantly reduced by the pyramid pooling module. At the same time, in contrast to previous models with attention mechanisms, a multi-head self-attention mechanism was incorporated by the network. Different segments of load features were focused on by each attention head, achieving the selection of crucial load characteristics from multiple perspectives and further enhancing the performance of load disaggregation. Finally, experiments on the UK-DALE and REDD datasets show that the proposed model outperforms four benchmark models in both load disaggregation performance and appliance operation state recognition ability.

Systemic application of effective antifungal drugs is the basic treatment for pulmonary mycosis, meanwhile, drug spraying under bronchoscope is one of the most important treatment options for tracheal, bronchial and pulmonary mycosis. Compared with bronchoscopic drug injection, indwelling guided drug injection cannula through nasal suspension with or without anchoring has more advantages in the treatment of pulmonary mycosis, including the ability to connect to a syringe pump for continuous and slow injection of drugs, which can avoid repeatedly performing bronchoscopy. This article describes the standard operating procedure of indwelling nasal cannula with or without anchoring for the treatment of pulmonary mycosis. [ABSTRACT FROM AUTHOR]

The treatment of mediastinal tumor has always been a clinical difficulty due to its complex anatomical location and many important organs. Compared with traditional local treatment, endobronchial ultrasound guided laser multi)point ablation of mediastinal tumors has many advantages, including real-time monitoring of ablation range and effect, avoidance of damage to normal tissue and organs, few side effects and good tolerance. This article describes the standard operating procedure for endobronchial ultrasound guided laser multi-point ablation of mediastinal tumors. [ABSTRACT FROM AUTHOR]

Objective To discusse a more simplified operation method on the basis of the combined operation of blepharoplasty with transverse incision for correction of epicanthus. Methods From June 2016 to June 2021, 273 patients with single-fold eyelids and epicanthus were treated by correction of epicanthus combined with blepharoplasty. The method of transverse incision medial canthoplasty combined with blepharoplasty was used. On the basis of traditional methods, the design line and operation sequence were adjusted to simplify the operation process. The correction effect of medial canthoplasty, the shape of double eyelids, and patient satisfaction after surgery were observed. Results Totally 273 patients were followed up for 6 to 18 months. In 257 patients, the epicanthus was fully corrected, the double eyelid was symmetrical and natural with inobvious scar. Basic correction of epicanthus was in 9 patients while the epicanthus was uncorrected in 7 patients. The efficiency rate was 97.44%. The patient satisfaction evaluation showed that 248 patients were very satisfied, 17 patients were relatively satisfied, and 8 patients were dissatisfied, with a satisfaction rate of 97.07%. Conclusion The modified transverse incision epicanthoplasty combined with blepharoplasty is a simple and effective technique. The correction of epicanthus is adequate, with little trauma, short recovery time and satisfied scarring outcomes. The contour of double-eyelid is natural and the postoperative outcome is satisfactory. [ABSTRACT FROM AUTHOR]
