Toll-like receptor,TLR (TLR) can sense invading pathogens,the acute inflammatory response in the body,chronic airway inflammation and pathophysiology of allergic diseases and play an important role in the immune defense response.Among them,TLR2,TLR4 most prominent role and become a hot research topic.This paper summarizes the importance of TLR2,TLR4 in the pathogenesis of respiratory tract infections,and pointed out by interfering with TLR2,TLR4 signal transduction pathway or reduced TLR2,TLR4g role may help to weaken the disease or improve the prognosis,which provides a new way of thinking and clues for the treatment of clinical common diseases.

The development and compilation of Evidence-based Guidelines of Clinical Practice with Acupuncture and Moxibustion: Adult Bronchial Asthma are introduced from three aspects, named the guideline methodology, the guideline structure and the guideline content. Based on the acupuncture-moxibustion practice and clinical research, the evidence-based medicine method is adopted. During the development and compilation of the guideline, the characteristics and advantages of acupuncture and moxibustion are specially considered in the treatment of this disease; the latest optimum evidences at home and abroad, experts' experience and patients' value are closely integrated with each other. Additionally, the worldwide accepted assessments of evidence quality and the recommendation (GRADE system) are combined with the clinical evidences of the ancient and modern famous acupuncture-moxibustion experts, and the clinical research evidences are with the experts' consensus to the large extent. The purpose of the guideline is to provide the maximal guidance to the clinical physicians.

BACKGROUND:Endoplasmic reticulum stress participates in the occurrence and development of many diseases, such as atherosclerosis, diabetes, and Alzheimer’s disease. GRP78 is a marker of endoplasmic reticulum stress. The expression of GRP78 reflects the degree of endoplasmic reticulum stress.
OBJECTIVE:To investigate the effect of cyclic stretch on GRP78 expression of L6 rat myoblasts, and to identify the relationship between cyclic stretch and endoplasmic reticulum stress.
METHODS:In vitro culture-tensile stimulation models of myoblasts of L6 rats were established successful y. The expression of GRP78 of myoblasts exposed to cyclic stretch was determined by reverse transcription-PCR and western blot assay. Stretch groups were subjected to 15%surface elongation at a frequency of 10 cycles per minute, over a period of 1, 6, 12 and 24 hours. cells were simultaneously seeded on a plate in the control and experimental groups with no stimulation.
RESULTS AND CONCLUSION:The expression of GRP78 mRNA was continuously elevated over time after stretched treatment, and significant differences were detected as compared with the control group (P<0.05). GRP78 protein expression began to increase at 1 hour after stretched treatment, was significantly increased at 6 hours, peaked at 24 hours, and significant differences were visible as compared with the control group (P<0.05). In conclusion, cyclic stretch induced the occurrence of endoplasmic reticulum stress, which was enhanced with prolonged time. However, prolonged stretch caused severe endoplasmic reticulum stress and leaded to apoptosis of myoblasts.

Objective:To investigate the application of artificial intelligence based on the neural network radiation field in repair of soft tissue defects at lower limbs.Methods:A retrospective analysis was performed of the 23 patients who had been admitted to Department of Orthopedic Surgery, Renmin Hospital of Wuhan University from June 2020 to May 2022 for soft tissue defects at lower limbs. There were 14 males and 9 females, aged (38.6±6.7) years. Causes for soft tissue defects: traffic injury in 9 cases, benign or malignant primary soft tissue tumor in 6 cases, mechanical injury in 4 cases, crush injury in 2 cases, and chronic ulcer in 2 cases. Defect locations: the thigh in 3 cases, the lower leg in 7 cases, and the ankle and distal foot in 13 cases. The areas of soft tissue defect ranged from 6.0 cm×3.8 cm to 14.7 cm×12.8 cm. The defects were repaired and reconstructed by transplantation of an anterolateral femoral free flap in 7 cases and a pedicled flap in 16 cases with the assistance of artificial intelligence based on the neural network radiation field, a cutting-edge artificial intelligence algorithm that can quickly construct and process three-dimensional model images through volume rendering under the radiation field. The flap survival rate, aesthetic satisfaction before and after treatment, time for skin flap harvesting and transplantation, functional recovery of lower limbs and incidence of complications were recorded.Results:All the 23 patients were followed up for 32(28, 36) weeks. All the flaps were harvested smoothly and survived. The time for flap harvesting and transplantation was 65.8(50.0, 76.0) min. The aesthetic satisfaction scored (2.3±0.7) points before treatment and (8.4±1.6) points 4 weeks after treatment, showing a statistically significant difference ( P<0.05). The skin flaps healed well with no complications such as hematoma or infection in all but one patient who suffered from superficial necrosis at the distal skin flap due to venous crisis but healed with a scar. On average, the functional recovery of lower limbs scored 23.7(22.0, 25.0) points at 12 weeks after operation according to the Enneking evaluation system, and the functional recovery of lower limbs was 79% (23.7/30.0). Conclusion:Application of artificial intelligence based on the neural network radiation field can achieve ideal results in repair of soft tissue defects at lower limbs, due to its advantages of rapid and accurate surgical procedures, limited damage to the donor site, and a short learning curve.

: Objective: To investigate the effects of ezrin enhancer knockout on ezrin gene expression, cell proliferation and migration of human esophageal carcinoma Eca-109 cells. : Methods: The CRISPR/Cas9 recombinant plasmids targeting upstream/downstream of human ezrin enhancer were co-transfected into human esophageal carcinoma Eca-109 cells, and the cell line Eca-C2 with ezrin enhancer knockout was screened by purinomycin. Then the expression levels of ezrin mRNAand protein in Eca-C2 cells were detected by Real-time quantitative PCR (qPCR) and Western blotting, respectively; The expression levels of MAPK-pathway-related proteins were detected by protein array technology; and the effects of ezrin enhancer knockout on the proliferation and migration of Eca-C2 cells were analyzed by WST-1 method and wound-healing assay, respectively. : Results:The human esophageal carcinoma cell line Eca-C2 with stable ezrin enhancer knockout was established successfully. Compared with control cells, the mRNA and protein expressions of ezrin in Eca-C2 cells were significantly reduced (all P<0.05).Among the 17 detected MAPK pathway related proteins in Eca-C2 cells, 9 proteins (AKT, CREB, GSK3b, MKK6, mTOR, P38, P53, P70S6K and RSK1) were down-regulated, and the cell proliferation and migration were significantly inhibited (all P<0.05). Conclusion: ezrin enhancer knockout can significantly inhibit the cell proliferation and migration of human esophageal carcinoma Eca-109 cells.
