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.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective To investigate whether interleukin-37(IL-37)affects macrophage M1 polarization via nu-cleotide oligomerization of structural domain receptor protein 1(NOD1)/nuclear factor κB(NF-κB)in plasma cell mastitis.Methods A total of 15 patients with plasma cell mastitis were recruited according to the collection standard as inflammatory breast tissue and normal breast tissue with a distance of ≥ 3 cm from the edge of the in-flammatory breast tissue.QPCR was performed to detect NOD1 and IL-3.Phorbol ester(PE)was used to induce THP-1 cells to differentiate into resting macrophages(M0).Lipopolysaccharide(LPS)combined with interferon(IFN-γ)was used to induce the polarization of M0 macrophages towards the M1 phenotype.NOD1 lentiviral RNA interference or over-expression vectors were constructed to regulate the expression of NOD1 in M1 macrophages.M0 macrophages were pretreated with IL-37 recombinant protein and then incubated with LPS and IFN-γ for induction.The expression of NOD1,IL-37,M1 markers(IL-6 and iNOS)and M2 markers(IL-10 and Arg-1)was quantified by qPCR.Western blot was employed to assess the protein level of NOD1,NF-κB p65,and p-NF-κB p65.Co-immunoprecipitation was used to detect the interaction between NOD1 and IL-37.Results Up-regulation of NOD1 and down-regulation of IL-37 as were found in inflammatory breast tissues(P＜0.05).Compared to M0 cells,M1 cells showed up-regulated NOD1 and M1 markers and the elevated phosphorylated NF-κB p65 but the down-regulated IL-37(P＜0.05).In M1 macrophages,both NF-κB inhibitor and NOD1 knockdown led to the down-regulation of NOD1 and M1 markers and caused a decrease in the phosphorylated NF-κB p65(P＜0.05).IL-37 recombinant protein decreased phosphorylation of NOD1,M1 marker and NF-κB p65,which was reversed by over-expression of NOD1.IL-37 may interact with NOD1(P＜0.05).Conclusions IL-37 may inhibit M1 polarization in macrophages by down-regulating NOD1/NF-κB pathway thereby preventing plasma cell mastitis progression.

Objective:To investigate the effects of unilateral ureteral obstruction on renal pelvic peristalsis and pacemaker cells in neonatal rats.Methods:An animal experimental study.Thirty-six 2-day-old newborn SD rats were randomly divided into the partial unilateral ureteral obstruction (PUUO) group, complete unilateral ureteral obstruction (CUUO) group, and sham operation group, with 12 rats in each group.One week after surgery, all rats were subjected to renal pelvic pressure (RPP) measurement by puncture.After measurement, the rats were euthanized, and their left renal pelvis and ureter were removed and fixed for histological examination.Parameters such as RPP, peristaltic wave frequency and amplitude at different perfusion speeds were recorded and compared, and the changes in pacemaker cells (atypical smooth muscle cells and Cajal-like interstitial cells) were also compared.The independent samples t-test was used for comparison between 2 groups, and the one-way ANOVA of variance was used for comparison among 3 groups. Results:In the sham operation group, the RPP increased gradually with the increase of perfusion speed; the frequency of peristaltic waves rose rapidly and then dropped after reaching the highest level with the increase of perfusion speed; similarly, the amplitude of peristaltic waves first increased and then decreased as the perfusion speed increased.In the PUUO group, the RPP increased rapidly with the increase of perfusion speed, higher than that in the sham operation group; the frequency of peristaltic waves was higher than that in the sham operation group, and it was relatively constant under the perfusion speed of 40 mL/h, but when the perfusion speed increased again, the frequency began to decline; the amplitude of peristaltic waves increased quickly and then declined at a faster rate than the sham operation group with the increase of perfusion speed.In the CUUO group, the basic RPP was 12 cmH 2O(1 cmH 2O=0.098 kPa); at the perfusion speed of 5 mL/h, the RPP rose gradually, and no plateau appeared; when the RPP reached 73 cmH 2O, the perfusate retrograded from the side of the puncture needle, then the RPP slightly decreased and then balanced, and no regular peristaltic waves were observed in the renal pelvis throughout the whole perfusion process.Immunofluorescence staining analysis showed the pacemaker cells were all located in the smooth muscle of the renal pelvic wall.The sham operation group had the highest positive rate, followed by the PUUO group and then the CUUO group. Conclusions:Ureteral obstruction has a significant impact on the peristalsis of the renal pelvis, and its impact on the peristaltic wave frequency and amplitude and RPP can be predicted.The reduction of pacemaker cells in the renal pelvis may be involved in the changes of renal pelvic peristalsis caused by ureteral obstruction, but further research is needed on how pacemaker cells regulate the peristalsis of the renal pelvis and ureter.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

  Objective  Different from other etiologies of early-onset scoliosis (EOS), congenital early-onset scoliosis (CEOS) is mainly linked to vertebral anomalies, such as formation failures and segmentation failures at the apex segments. So far, there is little research on CEOS patients who have completed traditional growing rods (TGR) treatment, and the initial outcomes of TGR with or without apical control technique (ACT) are different. Therefore, we compared the "final" results of CEOS patients who completed TGR treatment with or without ACT.  Methods  We conducted a retrospective study of CEOS patients who completed TGR treatment from 2007—2020. They either had final fusion or were followed up after reaching skeletal maturity. We split the patients into two groups based on whether they had ACT with TGR or not. The ACT-TGR group had apical vertebrectomy/hemivertebrectomy with short fusion and TGR. The TGR-only group had only TGR. We looked at their demographic features, radiographic measurements, and complications.  Results  This study enrolled 46 CEOS patients, of which 13 patients were in the ACT-TGR group and 33 patients in the TGR group. The ACT-TGR group had a longer distraction interval (1.17 years vs. 0.75 years). The ACT-TGR group had a larger preoperative main curve [87.00(63.50, 98.00)], but the residual curve degrees were comparable between the two groups at the last follow-up (P=0.354). At the last follow-up, the T1-12 and T1-S1 heights were similar between the two groups. The ACT-TGR group had a lower number of implant-related complications per patient (0.77 vs. 1.48). Three patients in the ACT-TGR group underwent final fusion, while 17 patients in the TGR group underwent final fusion (P=0.060).  Conclusions  Both ACT-TGR and traditional TGR coud effectively correct deformity and preserve spinal growth in CEOS patients. ACT-TGR had a better corrective effect on patients with severe deformity and did not have a significant impact on spinal height. For patients with acceptable correction, spontaneous fusion and without implant failure, retaining the implant and continuing observation could be a strategy for graduating from growing rod treatment.

Objective:To investigate the safety and prognosis of partial nephrectomy (PN) in the treatment of highly malignant non-clear renal cell carcinoma (nccRCC).Methods:Clinical data of 47 patients with cT 1N 0M 0 high malignant nccRCC treated in Changhai Hospital from March 2016 to March 2022 were retrospectively analyzed. All patients received PN. There were 34(72.3%) males and 13(27.7%) females. The mean age was (53.5±15.0) years, and average BMI, was(23.7±3.4)kg/m 2.The maximum tumor diameter was (29.8±12.6) mm, and R. E.N.A.L. score was 7(5-9), with 37(78.7%) cases of T 1a and 10(21.3%) cases of T 1b. The mean estimated glomerular filtration rate (eGFR) before surgery was (96.3±25.5) ml/ (min·1.73m 2). All patients underwent PN, including 1 patient (2.1%) undergoing open surgery, 29 patients (61.7%) undergoing laparoscopic surgery, and 17 patients (36.2%) undergoing robotic surgery. There were a total of 22(46.8%) cases of papillary cell carcinoma(pRCC)type Ⅱ, 4(8.5%) cases of collecting duct carcinoma (cdRCC), 9(19.1%) cases of MiT family translocated renal cell carcinoma (tRCC), 5(10.6%) cases of mucoid tubular and spindle cell carcinoma (mtSCC)and 7(14.9%) cases of unclassified renal cell carcinoma (uRCC). The surgical conversion rate, positive margin rate, operative time, intraoperative blood loss, complications, and postoperative hospital stay were analyzed. Preoperative and postoperative eGFR were analyzed, and overall survival (OS) and cancer specific survival (CSS) were calculated. Results:All the operations were successfully completed. No radical operation or open operation was performed, with operation time of(100±60) min and intraoperative blood loss of(100±59) ml. There were no intraoperative complication and 1 case (2.1%) suffered from postoperative complication. Postoperative hospital stay were 5 (4-6) days. The mean eGFR after surgery was (86.5±27.1) ml/(min·1.73m 2), and the difference was statistically significant ( P=0.041). In this study, the mean follow-up time was (45.7±20.9)months, and no adjuvant therapy was used after surgery. During the follow-up period, 2 patients died, who all of them were kidney cancer-related death, and both OS and CSS were 95.7% (45/47). Conclusions:PN is safe, feasible and has a good prognosis in the treatment of high malignant T 1 nccRCC. For tumors with clear imaging boundaries and complete envelope, complete tumor resection is more likely, postoperative follow-up should be strict, and no remedial radical or systemic treatment was required.
