Objective To evaluate the efficacy and safety of a novel intravascular lithotripsy(IVL)balloon—Vesscrack shockwave balloon—for vascular preparation before stent implantation in patients with severe coronary artery calcification(CAC).Methods This was a prospective,single-arm,multicenter study conducted in China from June 2022 to October 2022.Patients with severe CAC were treated with the Vesscrack shockwave balloon for lesion preparation,followed by drug-eluting stent(DES)implantation.Of these,33 patients underwent optical coherence tomography(OCT).The primary endpoint was procedural success,defined as successful stent implantation with residual stenosis≤30％and the absence of in-hospital major adverse events,including cardiac death,target vessel-related myocardial infarction,or target lesion revascularization.Results A total of 170 patients[mean age:(65.9±7.9)years,116 males]were enrolled.After treatment with IVL and DES,the minimum lumen diameter increased significantly compared to baseline[(2.34±0.40)mm vs.(0.95±0.33)mm,P＜0.001],the degree of stenosis was significantly reduced[(13.24±6.60)％vs.(65.18±10.59)％,P＜0.001].Procedural success was achieved in 100％of cases,and device success was 98.8％.The 30-day patient-related cardiovascular clinical composite endpoint(POCE)rate was 0.0,with no target lesion failure,no confirmed or potential thrombotic events were observed.The shockwave energy generator demonstrated excellent stability and ease of use.Among the 33 patients assessed with OCT,after IVL intervention,the maximum calcified area of the lumen[(3.51±1.51)mm2 vs.(2.85±1.80)mm2,P＜0.001],and the minimum lumen area within the target lesion[(3.08±1.04)mm2 vs.(2.02±0.75)mm2,P＜0.001],and after DES intervention,the luminal area of the largest calcified site[(6.59±1.64)mm2 vs.(2.85±1.80)mm2,P＜0.001]and the minimum luminal area within the target lesion[(6.19±1.45)mm2 vs.(2.02±0.75)mm2,P＜0.001]were significantly increased,and the differences were statistically significant.Conclusions The Vesscrack shockwave balloon is effective and safe for vascular preparation in patients with severe CAC prior to stent implantation.It achieves significant calcified plaque modification,high procedural success rates,and minimal complications.

Aim To observe the effect of lipopolysac-charide(LPS)induced supernatant of BV-2 cells on the inflammatory response and apoptosis of HT22 neu-rons.Methods After the concentration and time of LPS were determined by CCK-8 method,BV-2 cells were cultured with medium without LPS and medium containing LPS,the morphological changes of BV-2 microglia were observed by inverted microscope,and the CD86/CD206 ratio of BV-2 microglia was detected by immunofluorescence.Subsequently,BV-2 cell cul-ture supernatants were isolated and added to HT22 neuronal culture to observe the effect on the inflamma-tory response of HT22 neurons.The proliferation of HT22 neurons was detected by CCK-8 method and EdU method.The structural changes of HT22 neurons were observed under the microscope and examined by urani-um-lead staining.The levels of cytokines interleukin-1β(IL-1β),interleukin-10(IL-10),nuclear factor kappa-B(NF-κB)and tumor necrosis factor-α(TNF-α)were detected by enzyme-linked immunosorbent as-say(Elisa).Neuronal apoptosis was detected by the TUNEL method.The protein expressions of Bax,Bcl-2 and inflammatory factors were detected by Western blot.Results After induction with 1 mg·L-1 LPS,BV-2 cells exhibited increased cell body size,thicker protrusions on both side,and some cells showed de-formed protrusions,the CD86/CD206 ratio in BV-2 cells decreased,promoting the transformation of BV-2 cells from M2 type to M1 type.After treating with the culture supernatant of BV-2 cells,HT22 neuronal cell activity and proliferation were reduced,axons short-ened,and the number of cells decreased.Neuronal cell bodies were enlarged and some cells were de-formed,with damaged cell membranes,round cell nu-clei but displaced nucleoli from the normal position,swollen mitochondria with vacuoles,reduced internal ridge structures,and increased levels of inflammatory factors NF-κB,IL-1 β,and TNF-α(P＜0.05 or P＜0.01),while the anti-inflammatory factor IL-10 de-creased(P＜0.05),protein expression of the pro-apoptotic indicator Bax increased(P＜0.01),and the protein expression of the anti-apoptotic indicator Bcl-2 decreased(P＜0.05).Conclusion After induction of BV-2 cell polarization by LPS,the supernatant could inhibit HT22 neuronal cell viability,upregulate inflam-matory factor expression and promote apoptosis.

Aim To investigate the protective effects of Tilianin on lipopolysaccharide(LPS)-induced septice-mia-induced myocardial injury in rats and to explore the related mechanisms.Methods Animals were ran-domly grouped and a rat septicemia-induced myocardial injury model was constructed.Echocardiography was used to assess the cardiac function of rats,left ventricu-lar internal diameter at end-diastole(LVIDd)and left ventricular internal diameter at end-systole(LVIDs)were measured,and left ventricular ejection fraction(LVEF)and left ventricular fractional shortening(LVFS)were calculated;the kits were used to detect the serum activity of the relevant cardiac enzymes and the level of inflammatory factors;HE staining was used to observe the morphological changes of myocardium;immunofluorescence staining of cardiac tissues was used to detect the nuclear translocation of NF-κB p65;Western blot was used to detect the expression of TLR4,MyD88,p-NF-κB p65,and NLRP3 proteins in cardiac tissues.Results Compared with the model group,each administration group differently upregulated LVEF,LVFS,and LVIDs,and improved the coordina-tion of LV wall fluctuations in the model group of rats;cardiac enzymes LDH and CK-MB levels increased,and levels of inflammatory factors TNF-α,IL-6,and IL-1 β were reduced,exerting cardioprotective effects;HE staining showed that myocardial tissue cell gap was re-duced,myocardial fiber breakage was reduced,cardio-myocyte arrangement tended to be normal,and inflam-matory cell infiltration was reduced;NF-κB p65 entry into the nucleus was reduced,and phosphorylated NF-κB p65(p-NF-κB p65)expression was reduced;and Western blot results showed that the expression of TLR4,MyD88,and NLRP3 proteins was reduced.Conclusions Tilianin pretreatment reduces serum my-ocardial enzymes and inflammatory factors and im-proves myocardial injury in rats with septicemia-in-duced myocardial injury,which may be related to the Tilianin anti-TLR4/NF-κB/NLRP3 inflammatory signa-ling pathway.

Objective:To evaluate the effects of glutamine-enriched parenteral nutrition on short-term postoperative outcomes compared with conventional nutritional support in colorectal cancer patients with enteral nutrition intolerance after surgery.Method:A retrospective cohort study was conducted to collect clinical data from colorectal cancer patients who underwent radical resection at the Department of Gastrointestinal Surgery of Zunyi Medical University Affiliated Hospital from January 2019 to December 2021.The differences in postoperative complication rates,perioperative nutritional indicators,and inflammatory factors between the two groups were analyzed.SPSS 29.0 software was used for statistical analysis.Result:Based on whether glutamine was added to parenteral nutrition,178 patients were divided into a control group(conventional nutritional therapy,n=120)and an observation group(glutamine enhanced nutritional therapy,n=58).The incidence of postoperative complications(Clavien Dindo grade≥III)in the control and observation groups was 14.17%(17/120)and 3.45%(2/58),respectively,with a statistically significant difference(P=0.030).The observation group recovered faster than the control group in terms of time to first expectoration,defecation and intake of liquid diet after surgery,and had a shorter hospital stay after surgery(P<0.05).However,there was no significant difference in the 30-day readmission rate between the two groups(P=0.393).There was no statistically significant difference in the changes in total protein,albumin,pre-albumin,neutrophil/lymphocyte ratio and endogenous creatinine clearance rate between the two groups of patients after surgery(P>0.05).There were also significant differences in the changes in lymphocyte count,white blood cell count,neutrophil percentage,alanine aminotransferase,aspartate aminotransferase,total bilirubin,and urea nitrogen levels between the two groups of patients after surgery(P<0.05).Conclusion:Compared with regular nutritional support,postoperative parenteral glutamine supplementation can reduce the incidence of postoperative complications in colorectal cancer patients,promote recovery of bowel function,shorten postoperative hospital stay,improve patient immune function and reduce inflammatory levels.

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.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

Objective:To explore the value of 18F-FDG PET brain imaging in the auxiliary diagnosis of autoimmune encephalitis (AE) before treatment, and to analyze the regional and course-related characteristics of brain metabolic changes. Methods:The 18F-FDG PET brain imaging data of 49 AE patients (26 males, 23 females, age 48.0(29.0, 61.0) years) who did not receive first-line immunotherapy were retrospectively analyzed. Patients were collected from Renji Hospital, Shanghai Jiao Tong University School of Medicine, between July 2015 and December 2023. Forty-nine age- and gender-matched healthy subjects who underwent routine physical examination at the same time period were selected as the healthy controls (HC). The statistical parametric mapping (SPM) 8 two-sample t test ( P<0.001, k=50) was used to compare the imaging results of AE patients with those of HC. The screening results were adjusted by the cluster-level family-wise error rate (FWER) for P<0.05. Metabolic abnormalities associated with AE were identified, and differences in metabolic patterns at different stages of the disease course (short: ≤1 month; medium: >1 month and ≤3 month; long: >3 month) were compared by subgroup analysis. Mann-Whitney U test was used to analyze the data. Results:In the included AE patients, regions with elevated metabolism were mainly located in the limbic lobe, insula, putamen, and amygdala ( t values: 3.18-5.07, Z values: 3.17-4.76), while local metabolic reduction was observed in the frontal, parietal, and occipital lobes ( t values: 3.18-5.43, Z values: 3.23-5.06), with most of these regions passing FWER correction. In patients with anti- N-methyl- D-aspartate receptor (NMDAR) encephalitis, local metabolism increased in the right superior temporal gyrus ( t values: 3.55-4.79, Z values: 3.67-3.86) and decreased in the left middle temporal gyrus and inferior frontal gyrus ( t values: 3.55-5.43, Z values: 3.45-4.21), but the results did not pass the FWER correction. Subgroup analysis showed that in patients with short disease course ( n=17), regions with locally elevated metabolism included the brainstem, limbic lobe, and cerebellum ( t values: 3.37-5.27, Z values: 3.52-4.44), while regions with reduced metabolism were mainly located in the frontal, parietal, and occipital lobes ( t values: 3.37-6.77, Z values: 3.34-5.30), and these abnormal results all passed FWER correction. In patients with medium ( n=7) to long ( n=25) disease course, the regions with metabolic abnormalities were significantly reduced and did not pass FWER correction. Conclusions:18F-FDG PET can accurately identify brain metabolic abnormalities in AE patients, demonstrating significant regional and course-related characteristics. Metabolic abnormalities are more pronounced in patients with short disease course, while they are relatively less obvious in patients with medium to long disease course.
