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.

This research aims to construct a stable epithelial cell senescence model for screening and e-valuation of senolytics.We explored the optimal conditions for doxorubicin-induced senescence of non-transformed epithelial cells MCF 10A,including the optimal induction concentration,the optimal inter-vention time,and the optimal senescence duration,and confirmed the feasibility of MCF 10A as an epi-thelial senescence model by multiple ways.The optimal condition for Doxorubicin-induced senescence of MCF 10A cells was treatment with 0.6 μmol/L Doxorubicin for 16 h to achieve the best senescence state on the 8th day.Under the optimal induction conditions,the positive rate of senescence-associated β-gal-actosidase(SA-β-gal)staining in the treated group reached 97％.At the same time,biochemical results of detecting the expression of mRNA,proteins,and immunofluorescence demonstrated that the expression levels of senescence-associated secretory phenotype(SASP),p16,p21 and p53 in the treated group were significantly higher than those in the control cells,and Lamin B1 was significantly decreased(P＜0.001),which were consistent with the specific characteristics of senescence.In summary,an epithelial senescence model was successfully induced in MCF 10A cells by Doxorubicin in this study,which will promote the screening of senolytics for senescent epithelial cells.

ObjectiveThe purpose of this study was to evaluate the functional outcomes and satisfaction in periprosthetic knee infection patients after above-the-knee amputation （AKA）. MethodsA review was performed in 13 patients who underwent AKA due to periprosthetic knee infection from October 2010 to August 2022， there were 7 females and 6 males with the median age of 69 （45~ 73） years. The mean number of surgical procedures between primary total knee arthroplasty and AKA was 2.9 times （range： 1 ~ 6）. Patients were segregated into non-elderly group （including patients <65 years old） and elderly group （involving patients ≥65 years old）. Functional outcomes were evaluated by SF-12 and Barthel activities daily living index （Barthel ADL index）. Patient satisfaction was accomplished through a questionnaire. ResultsFour patients died within 6 months after the amputation. Three patients received surgical procedures for recurrent infections after AKA. In the remaining 9 patients，the median time from AKA to the final follow-up was 4.2 （1.9~8.2） years， three patients received surgical procedures for recurrent infections after AKA. Patients in non-elderly group showed better functional outcomes than elderly patients after AKA （both P<0.05）. All patients in non-elderly group were fitted with a prosthesis. Whereas， elderly patients reported a better satisfaction after AKA than young patients. ConclusionYoung PJI patients seemed to have better function and ambulatory ability with high expectation and demand， which made them feel less satisfied about AKA. Meanwhile，despite poor function outcomes due to the less healthy physical condition， the alleviation of financial and psychological burdens resulting from reinfections and multiple surgeries and the less demand in function and daily activities made elderly patients have a good satisfaction after AKA.

OBJECTIVE: To investigate the relationship among the gross motor function classification system (GMFCS)and the development of hip joint and lumbar spine in children with spastic cerebral palsy. METHODS: The clinical data of 125 children with spastic cerebral palsy admitted from January 2018 to July 2021 were retrospectively analyzed. There were 85 males and 40 females, aged from 4 to 12 years old with an average of (8.4±2.9) years. According to GMFCS, the patients were divided into gradeⅠ, Ⅱ, Ⅲ and Ⅳ groups. There were 27 cases in gradeⅠgroup, 40 cases in gradeⅡgroup, 35 cases in grade Ⅲ group and 23 cases in grade Ⅳ group. The migration percentage(MP), central edge angle(CE), neck-shaft angle(NSA), acetabular index(AI) were measured by the radiograph of pelvis, abnormal parameters were selected to evaluate the relationship between different GMFCS grades and hip joint development. Lumbar sagittal Cobb angle, lumbar sacral angle, lumbar lordosis index and apical distance were measured by lateral lumbar radiographs to evaluate the relationship between different GMFCS grades and lumbar spine development. RESULTS: ①Among the 125 spastic cerebral palsy children, there were 119 cases of pelvic radiographs that met the measurement standards. In the four groups with gradeⅠ, Ⅱ, Ⅲ, Ⅳ, MP was (22.72±3.88), (26.53±4.36), (33.84±4.99), and (49.54±7.87)%, CE was(30.10±6.99) °, ( 22.92±4.19) °, ( 17.91±5.50) °, and (-0.70±17.33)°, AI was (16.41±2.77) °, (20.46±4.63) °, (23.76±5.10) °, and ( 29.15±7.35)°, respectively, there were significant differences between the two comparisons (P<0.05). And the higher GMFCS grade, the greater MP and AI, and the smaller CE.The NSA was(142.74±10.03) °, (148.66±9.09) °, (151.66±10.52) °, and (153.70±8.05)° in four groups with gradeⅠ, Ⅱ, Ⅲ, Ⅳ, respectively. The differences between the two comparisons of the GMFCS gradeⅠgroup and the other three groups were statistically significant (P<0.05). NSA of GMFCSⅠgroup was significantly lower than that of the others, there was no significant difference among other groups(P>0.05). ② Among the 125 spastic cerebral palsy children, there were 88 cases of lumbar spine radiographs that met the measurement standards. ③The lumbar sagittal Cobb angle was(32.62±11.10) °, (29.86±9.90) °, (31.70±11.84) °, and (39.69±6.80)° in the four groups with gradeⅠ, Ⅱ, Ⅲ, Ⅳ, respectively;GMFSS of grade Ⅳ group was significantly higher than that of other three groups, there was significant difference between the two comparisons (P<0.05);there were no significant differences between other groups (P>0.05). In the four groups with gradeⅠ, Ⅱ, Ⅲ, Ⅳ, the lumbosacral angle was (31.02±9.91) °, ( 26.57±9.41) °, (28.08±8.56) °, and ( 27.31±11.50)°, the lumbar lordosis index was (4.14±12.89), (8.83±13.53), (13.00±11.78), and (10.76±9.97) mm, the arch apex distance was (9.50±6.80), (6.68±3.20), (7.16±4.94), and (6.62±4.13) mm, respectively, there were no significant differences between the two comparisons(P>0.05). CONCLUSION ①In children with GMFCS gradeⅠ-Ⅳ, the higher the GMFCS grade, the worse the hip develops. ② Children with GMFCS grade Ⅲ-Ⅳ may be at greater risk for lumbar kyphosis.

Protein-protein interactions (PPI) are involved in a variety of biological processes, including cell-to-cell interactions, metabolism and development control. The misregulation, post-translational modification and interference of PPI are related to a variety of human diseases, making the regulation of these interactions a very attractive field of drug discovery. In recent years, the interaction between MDM2 and p53 has become a research hotspot, which plays an important role in the treatment of tumors. But unfortunately there are no such inhibitors approved all over the world. In this view, recent advances of MDM2-p53 inhibitors were briefly described and its inhibitors with potential therapeutic activities in clinical studies were introduced.

In recent years， the incidence of neurological diseases has been increasing year by year. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of neurological disorders， identify the breakthrough point of integrating TCM with western medicine， and further standardize the clinical diagnosis and treatment of TCM， the China Association of Chinese Medicine organized neurologists in TCM and western medicine to carry out in-depth discussion on the neurological diseases responding specifically to TCM and integrated TCM and western medicine， such as stroke， headache， vertigo， multiple sclerosis， and epilepsy， aiming to formulate a well-recognized and integrated treatment protocol for TCM and western medicine and improve the efficacy of neurological disorders. Furthermore， the treatment suggestions of the corresponding diseases in TCM and western medicine were proposed to provide references for clinical practice and scientific research.

Objective: To evaluate the 4-year clinical outcomes of patients following Firesorb bioresorbable scaffold (BRS) implantation. Methods: The study reported the 4-year follow-up results of the FUTURE I study. FUTURE I was a prospective, single-center, open-label, first-in-man study which evaluated the feasibility, preliminary safety, and efficacy of Firesorb stent in the treatment of coronary artery stenosis. A total of 45 patients with single de novo lesions in native coronary arteries ,who hospitalized in Fuwai Hospital from January to March 2016 were enrolled. After successfully stent implantation these patients were randomized in a 2∶1 ratio into cohort 1 (n=30) or cohort 2 (n=15). The patients in cohort 1 underwent angiographic, IVUS or OCT examination at 6 months and 2 years; and cohort 2 underwent angiographic, IVUS or OCT at 1 and 3 years. All patients underwent clinical follow-up at 1, 6 months and 1 year and annually thereafter up to 5 years. The primary endpoint was target lesion failure (TLF, including cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization). Secondary endpoints included patient-oriented composite endpoint (PoCE, defined as composite of all death, all miocardial infarction, or any revascularization). Results: A total of 45 patients were enrolled and implanted with Firesorb BRS, including 35 males (77.8%), and the age was (54.4±9.3) years. At 4 years, 10 patients in cohort 1 were reexamined by coronary angiography and OCT examination. Among them, 2 patients' stents were completely degraded and absorbed. Compared with the OCT images of the other 8 patients in cohort 2 at 3 years, the degree of stent degradation was increased, and no stent adherence was found. The 4-year clinical follow-up rate was 100%. In 4-year clinical following up, 2 patients suffered PoCE (4.4%): 1 patient underwent non-target vessel revascularization the day after index procedure and target vessel revascularization (Non-target lesion revascularization) at 2-year imaging follow-up; the other patient underwent target lesion revascularization during imaging follow-up at 4 years but not due to ischemic driven. There was no scaffold thrombosis or TLF events through 4 years. Conclusions: Four years after the implantation, complete degradation and absorption of the Firsorb stent are evidenced in some patients. Firesorb stent is feasible and effective in the treatment of patients with non-complex coronary lesions.
