Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

BACKGROUND:Previous studies have demonstrated that moxibustion can alleviate osteoarthritis-induced cartilage lesions and delay the progression of knee osteoarthritis. In a previous study conducted by our research group,it was found that regulating the circPan3/miR-667-5p/Ghrelin signaling pathway can enhance the level of autophagy in chondrocytes,thereby exerting a cartilage protective role in knee osteoarthritis. OBJECTIVE:To explore the effect of moxibustion on knee osteoarthritis cartilage in rats based on the circPan3/miR-667-5p/Ghrelin signaling pathway. METHODS:Sprague-Dawley rats were randomly divided into three groups (n=10 per group):sham operation,model,and moxibustion groups. A rat model of knee osteoarthritis was established in the latter two groups by anterior cruciate ligament transection and medial meniscus resection. Rats in the sham operation group underwent arthrotomy only. At 6 weeks after modeling,moxibustion intervention at Zusanli and Shenyu acupoints was applied in the moxibustion group,20 minutes daily for 4 weeks,while the other two groups did not receive any special treatment. After 4 weeks,histopathological staining was performed to observe the degree of synovial lesions and cartilage damage in the knee joint. Additionally,changes in the serum levels of inflammatory cytokines,interleukin-6 and tumor necrosis factor-α,were detected by enzyme-linked immunosorbent assay. Furthermore,chondrocytes isolated from the above three groups of rats were divided into three groups:a normal control group,a model group,and a moxibustion group. The expression levels of cartilage matrix anabolic molecules (type Ⅱ collagen and Sox9),matrix degradation molecules (matrix metalloproteinase 13 and ADAMTS5),autophagy markers (ATG5,Beclin-1,microtubule-associated protein 1 light chain 3),Ghrelin,CircPan3,and miR-667-5P were determined by western blot and qRT-PCR in each group. RESULTS AND CONCLUSION:After 4 weeks of treatment,the model group exhibited significant thickening of the synovium,infiltration of inflammatory cells,narrowing of the joint space,rough and uneven cartilage surfaces,thinning,reduction in the number of chondrocytes,a significant increase in synovitis and Osteoarthritis Research Society International scores,and a significant up-regulation of interleukin-6 and tumor necrosis factor-α levels (P<0.0001). In comparison,the sham operation group showed no significant changes. Compared with the model group,the moxibustion group exhibited a reduction in synovial thickening,a decrease in inflammatory cell infiltration,an increase in joint space,a reduction in cartilage roughness and loss of integrity,an increase in the number of chondrocytes,a reduction in synovitis and Osteoarthritis Research Society International scores,and a significant reduction in the levels of interleukin-6 and tumor necrosis factor-α (P<0.0001). The results of in vitro experiments demonstrated that the expression of matrix metalloproteinase 13,ADAMTS5,and miR-667-5P was elevated,while the expression of type Ⅱ collagen,Sox9,autophagy markers,Ghrelin,and Circpan3 was reduced in the model group compared with the normal control group (P<0.01). Moxibustion was found to reverse these changes in the moxibustion group compared with the model group (P<0.01). To conclude,moxibustion may enhance chondrocyte autophagy by modulating the circPan3/miR-667-5p/Ghrelin signaling pathway,which may inhibit knee osteoarthritis inflammation and cartilage destruction,exerting a protective effect on cartilage.

OBJECTIVES: This study aimed to evaluate the filling effects of three biomaterial root canal sealers [iRoot SP, C-Root SP, and GuttaFlow Bioseal (GFB)] by using Micro-CT. METHODS: Sixty single-canal detached premolars were selected. After crown amputation, their uniform working length was set at 12 mm and prepared to a 06 taper 30# with M3 nickel-titanium file. The samples were randomly divided into six groups with different sealers and obturation techniques: iRoot SP+single-cone technique (SC), C-Root SP+SC, GFB+SC, iRoot SP+single cone-mediated ultrasonic technique (SU), C-Root SP+SU, and GFB+SU. Samples were scanned by Micro-CT, and the total and segmented filling rates were calculated with Mimics 22.0 software after 3D reconstruction. RESULTS: The overall filling rate of the three biomaterial root canal sealers was higher than 90%. The overall and coronal third and middle third segment filling rate of groups iRoot SP+SC, C-Root SP+SC was higher than that of group GFB+SC (P<0.01), with no significant difference between groups iRoot SP+SC and C-Root SP+SC (P>0.05). On the apical third, no significant difference was found among each group (P>0.05). The overall and segment filling rate of groups iRoot SP+SU and C-Root SP+SU was higher than that of GFB+SU (P<0.01), with no significant difference between groups iRoot SP+SU and C-Root SP+SU (P>0.05). The filling rate of the apical 1/3 of group C-Root+SC was lower than that of group C-Root+SU (P<0.01), and the filling rate of the coronal 1/3 of group GFB+SC was higher than that in the GFB+SU (P<0.01). Nevertheless, no significant difference was found in other filling rate of two obturation techniques (P>0.05). CONCLUSIONS The overall filling rate of the three biomaterial root canal sealers using SC and SU are satisfactory. iRoot SP and C-Root SP have similar filling rates, which are significantly higher than that of GFB. C-Root SP combined with SU technique can improve the filling quality of the root apical.

Autoimmune hepatitis （AIH） is an autoimmune disease characterized by chronic liver inflammation， with a gradually increasing incidence rate， and its social and medical burdens cannot be neglected. Intestinal microecology is becoming a research hotspot in the field of autoimmune disease. In recent years， it has been believed that changes in intestinal microecology can cause changes in autoimmune state， microbial metabolites， and intestinal barrier， which is one of the driving factors for the onset of AIH. Early diagnosis and correct treatment can help to improve the prognosis of AIH patients. This article introduces the characteristics of gut microbiota in AIH patients， elaborates on the impact of intestinal microflora imbalance on the pathogenesis of AIH， and briefly describes related treatment regimens from the perspective of intestinal microecology， so as to comprehensively understand and explain the role of intestinal microecology in AIH and the impact of intestinal microecology balance on the pathogenesis， diagnosis， and treatment of AIH.
