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.

Objective To explore the spatiotemporal expression patterns of Patched 1(Ptch1)and insulin enhancer binding protein-1(Isl 1)in mouse embryonic foregut and their relationship with the early development of trachea-main bronchus.Methods The foregut of 60 mouse embryos at E9.5-12.5 was separated for the detection of Isl1 and sonic hedgehog(Shh)protein by Western blotting.Serial paraffin sections of 6 mouse embryos at E9.5-14.5 were taken for immunohistochemical staining and immunofluorescence double staining with Isl1,Ptch1,forkhead box protein A2(Foxa2),type Ⅱ collagen α1 chain(Col2a1)and α-smooth muscle actin(α-SMA),as well as HE staining and Masson staining.Results The expression trend of Isl1 and Shh in foregut endoderm at E9.5-12.5 was similar,and the peak of Shh expression was later than Isl1.The foregut developed into the trachea at E9.5-12.5,Ptch1 was expressed in the thickening and protrusion of the respiratory endoderm,the laryngal-tracheal groove and the solid cell cord,accompanied by the increase and aggregation of Isl1-positive mesenchymal cells,forming a characteristic pyramidal structure centered on the respiratory endoderm and the solid cell cord;The main bronchus appeared at E12.5-13.5,Ptch1 was only expressed in its lateral wall,accompanied by the accumulation of Isl1-positive mesenchymal cells;The trachea-main bronchial epithelium lost Ptch1 expression and the surrounding Isl 1-positive mesenchymal cells also decreased rapidly at E13.5-14.5.Co12a1-positive chondrocytes first appeared in the Isl1-positive mesenchymal area adjacent to the Ptch1-positive epithelium at E12.5;Col2a1-positive cartilage was nested within the Isl1-positive mesenchymic area in a"C"shape and expanded in a proximal-distal pattern at E12.5-13.5;Col2a1-positive cartilage extended to the dorsal trachea beyond the Isl1-positive mesenchyma and encircles α-SMA positive smooth muscle in a circular manner at E14.5.Conclusion The expression of Ptch1 in the foregut endoderm is involved in the development and morphogenesis of the trachea-main bronchus epithelium,and is closely related to the proliferation and aggregation of Isl1-positive mesenchyme in the trachea-main bronchial wall,Subsequently,they jointly determine the time,location and extent of airway cartilage.

Objective:To investigate the impact of early invasive arterial blood pressure (IBP) monitoring on survival and neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR).Methods:This retrospective cohort study analyzed 44 OHCA patients receiving ECPR between January 2021 and January 2023. Patients were divided into: Early intervention group : IBP established within 3 min of ECMO initiation; Late intervention group : IBP established after ICU admission. Baseline characteristics, ECMO parameters, and clinical outcomes were compared. Multivariable logistic regression (adjusted for age, initial rhythm, etc.) and Spearman's correlation were used.Results:This study included a total of 44 patients treated with OHCA and ECPR, divided into an early intervention group of 23 cases and a late intervention group of 21 cases. The early intervention group showed significantly higher: Survival to discharge (43.5% vs. 9.5%, P<0.05), Good neurological recovery (CPC 1-2: 34.8% vs. 9.5%, P<0.05).Early intervention independently predicted survival (adjusted OR=18.84, 95% CI:1.97-179.98, P=0.01). Stratified analysis by pH (cutoff 7.0) demonstrated consistent benefits in both pH>7.0 ( aOR=0.392, 95% CI:0.106-0.678) and pH≤7.0 subgroups ( aOR=0.385, 95% CI: 0.075-0.695; interaction P=0.183). Early IBP positively correlated with CPC scores ( ρ=0.40, P=0.007). Conclusions:Early IBP monitoring significantly improves survival and neurological outcomes in OHCA-ECPR patients, supporting its integration into standardized protocols.

Objective:To investigate the value of CT radiomic model based on analysis of primary gastric cancer and the adipose tissue outside the gastric wall beside cancer in differentiating stage T1-2 from stage T3-4 gastric cancer.Methods:This study was a case-control study. Totally 465 patients with gastric cancer treated in Affiliated People′s Hospital of Jiangsu University from December 2011 to December 2019 were retrospectively collected. According to postoperative pathology, they were divided into 2 groups, one with 150 cases of T1-2 tumors and another with 315 cases of T3-4 tumors. The cases were divided into a training set (326 cases) and a test set (139 cases) by stratified sampling method at 7∶3. There were 104 cases of T1-2 stage and 222 cases of T3-4 stage in the training set, 46 cases of T1-2 stage and 93 cases of T3-4 stage in the test set. The axial CT images in the venous phase during one week before surgery were selected to delineate the region of interest (ROI) at the primary lesion and the extramural gastric adipose tissue adjacent to the cancer areas. The radiomic features of the ROIs were extracted by Pyradiomics software. The least absolute shrinkage and selection operator was used to screen features related to T stage to establish the radiomic models of primary gastric cancer and the adipose tissue outside the gastric wall beside cancer. Independent sample t test or χ2 test were used to compare the differences in clinical features between T1-2 and T3-4 patients in the training set, and the features with statistical significance were combined to establish a clinical model. Two radiomic signatures and clinical features were combined to construct a clinical-radiomics model and generate a nomogram. The area under the receiver operating characteristic curve (AUC) was used to evaluate the efficacy of each model in differentiating stage T1-2 from stage T3-4 gastric cancer. The calibration curve was used to evaluate the consistency between the T stage predicted by the nomogram and the actual T stage of gastric cancer. And the decision curve analysis was used to evaluate the clinical net benefit of treatment guided by the nomogram and by the clinical model. Results:There were significant differences in CT-T stage and CT-N stage between T1-2 and T3-4 patients in the training set ( χ2=10.59, 15.92, P=0.014, 0.001) and the clinical model was established. After screening and dimensionality reduction, the 5 features from primary gastric cancer and the 6 features from the adipose tissue outside the gastric wall beside cancer established the radiomic models respectively. In the training set and the test set, the AUC values of the primary gastric cancer radiomic model were 0.864 (95% CI 0.820-0.908) and 0.836 (95% CI 0.762-0.910), and the adipose tissue outside the gastric wall beside cancer radiomic model were 0.782 (95% CI 0.731-0.833) and 0.784 (95% CI 0.702-0.866). The AUC values of the clinical model were 0.761 (95% CI 0.705-0.817) and 0.758 (95% CI 0.671-0.845), and the nomogram were 0.876 (95% CI 0.835-0.917) and 0.851 (95% CI 0.781-0.921). The calibration curve reflected that there was a high consistency between the T stage predicted by the nomogram and the actual T stage in the training set ( χ2=1.70, P=0.989). And the decision curve showed that at the risk threshold 0.01-0.74, a higher clinical net benefit could be obtained by using a nomogram to guide treatment. Conclusions:The CT radiomics features of primary gastric cancer lesions and the adipose tissue outside the gastric wall beside cancer can effectively distinguish T1-2 from T3-4 gastric cancer, and the combination of CT radiomic features and clinical features can further improve the prediction accuracy.

Objective To investigate the role of inhibition of Runt-associated transcription factor 1(Runx1)expression in arterial interventional chemotherapy for lung cancer in rats.Methods A549 cells were randomly divided into control group(normal cultured cells),si-NC group(transfected with si-NC plasmid),si-Runx1 group(transfected with si-Runx1 plasmid).Cell proliferation was detected by cell counting kit-8(CCK-8)assay,and the relative expression level of protein was detected by Western blotting.Rats were randomly divided into model group(constructed lung cancer transplanted tumor rats),sh-Runx1 group(knockdown Runx1 expression),OXA arterial group(single arterial interventional chemotherapy),sh-Runx1+OXA group(knockdown Runx1+intravenous chemotherapy),sh-Runx1+OXA arterial group(knockdown Runx1+arterial interventional chemotherapy).After continuous treatment for 3 weeks,tumor volume and weight were measured,TdT mediated dUDP nick end labeling(Tunel)assay was used to detect tumor apoptosis,and Western blot assay was used to detect the expression of migration and invasion-related proteins.Results The survival rates of A549 cells in the control group,si-NC group and si-Runx1 group were(100.00±5.13)％,(99.56±3.44)％and(60.96±7.00)％,respectively;the expression levels of Runx1 protein were 0.84±0.06,0.85±0.06 and 0.20±0.03,respectively.Compared with the control group and si-NC group,the cell survival rate and Runx1 protein expression level in the si-Runx1 group were significantly decreased(all P＜0.05).The tumor volume of the model group,sh-Runx1 group,OXA arterial group,sh-Runx1+OXA group and sh-Runx1+OXA arterial group after the last treatment were(1 069.58±121.79),(819.30±6.98),(639.34±66.64),(486.91±29.88),(416.57±21.58)mm3,respectively;the apoptosis rates were(4.32±0.36)％,(13.95±1.22)％,(15.46±1.14)％,(23.71±2.01)％,(31.16±3.04)％,respectively;the expression levels of E-cadherin protein were 0.31±0.05,0.61±0.07,0.67±0.09,0.92±0.07,1.23±0.13,respectively.The above indexes of sh-Runx1 group,OXA arterial group,sh-Runx1+OXA group and sh-Runx1+OXA arterial group were compared with those of the model group,and the difference was statistically significant(all P＜0.05).The above indexes of sh-Runx1+OXA arterial group were compared with those of sh-Runx1,OXA arterial group and sh-Runx1+OXA group,and the difference was statistically significant(all P＜0.05).Conclusion inhibition of Runx1 can enhance the apoptosis induction and cell metastasis inhibition of arterial interventional chemotherapy in lung cancer rats.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective:To assess the clinical effect and safety of comprehensive therapy of traditional Chinese medicine(TCM)in the treatment of erectile dysfunction(ED)with damp-heat stasis.Methods:We selected 108 cases of ED with damp-heat stasis meeting the inclusion criteria and treated with tadalafil(the control group,n=54)or tadalafil+comprehensive TCM therapy(the trial group,n=54)in the First Affiliated Hospital of Henan University of Chinese Medicine in the same period.After 8 weeks of treatment,we recorded the patients'scores on IIEF-5,TCM syndrome,erectile quality(EQS),9-Item Patient Health Questionnaire(PHQ-9)and Generalized Anxiety Scale 7(GAD-7).At 16 weeks of our study,we collected the efficacy parameters,safety indicators and adverse reactions by telephone follow-up and compared the data obtained between the two groups of patients.Results:Totally,103 of the patients completed the study,51 in the control and 52 in the trial group.Compared with the baseline,the IIEF-5 and EQS scores were both markedly increased after 8 weeks of treatment in the trial group(12.35±3.00 vs 18.36±2.82,P＜0.05;39.5[30.25-43]vs 67.5[54.5-76.75],P＜0.05)and the control(11.96±2.79 vs 15.88±3.86,P＜0.05;38.0[29-42]vs 56[49-64],P＜0.05),even more significantly in the former than in the latter(P＜0.05);the TCM syndrome and GAD-7 scores were remarkably decreased in the trial(9.5[8-12]vs 4.0[2.25-5],P＜0.05;5[2.25-6.75]vs 2.5[1-4.75],P＜0.05)and the control group(10.0[8-12]vs 5.0[3-6],P＜0.05;5.0[3-6]vs 4.0[2-5],P＜0.05),even more signif-icantly in the former than in the latter(P＜0.05),so were the PHQ-9 scores(P＜0.05),but with no statistically significant differ-ence between the two groups(P＞0.05).The IIEF-5 scores of the two groups remained significantly higher than the baseline during the follow-up(P＜0.05),even higher in the trial than in the control group(17.04±2.60 vs 14.16±3.34,P＜0.05).No obvious abnormal safety indicators or adverse events were observed during the study.Conclusion:Comprehensive TCM therapy combined with tadalafil is superior to tadalafil alone in the treatment of ED with damp-heat stasis,and has a better long-term efficacy and a higher safety.

Objective:To investigate the clinical effect of pulsed thulium laser(PTL)combined with triamcinolone acetonide injection in the treatment of failed posterior urethral anastomosis(FPUA).Methods:This retrospective study included 35 male pa-tients treated in Gongli Hospital for failed posterior urethral anastomosis from January 2018 to December 2023.All the patients under-went direct-vision internal urethrotomy(DVIU)with transurethral PTL(the PTL group,n=15)or transurethral plasma(the TUP group,n=20),and all received intralesional injection of triamcinolone acetonide.We followed up the patients for a median of 21 months,recorded the age,length of urethral stricture,operation time,pre-and post-operative maximum urinary flow rate(Qmax),postoperative complications and recurrence of urethral stricture,and compared the data obtained between the two groups.Results:All the patients smoothly completed the treatment procedures.No statistically significant differences were observed in the age,length of urethral stricture,operation time and postoperative complications between the two groups(P>0.05).The median follow-up time for the thulium laser group and plasma group was 21.0 months(IQR 16.0-24.0)and 21.0 months(IQR 17.0-25.0),respectively,with a statistically significant difference observed in the maximum urine flow rate before and after surgery at the 12-month mark(P<0.01).No significant disparity was found in terms of relapse-free survival between the two groups(P=0.398)Conclusion:Pulsed thulium laser combined with triamcinolone acetonide injection can effectively maintain a short-term cicatricial stability of the ure-thral stricture and satisfactory urethral patency,obviously superior to plasmotomy as a remedial treatment of urethral stricture after failed posterior urethral anastomosis.
