OBJECTIVE: To explore the safety and effectiveness of separation surgery in patients with neurological symptoms of spinal metastases. METHODS: From January 2020 to December 2022, 14 patients with neurological symptoms of spinal metastases underwent separation surgery, including 7 males and 7 females, aged from 30 to 76 years old with an average of (61.57±12.16) years old. In comparison with eleven patients underwent conservative treatment during the same period, including 6 males and 5 femals, aged from 46 to 88 years old with an average of (66.55±12.32) years old. The changes in visual analogue scale (VAS), Frankel grades, Karnofsky scores, and quality of life score (QOL) before and after treatment were compared between two groups. RESULTS: Fourteen patients in the separation surgery group underwent surgery successfully, with surgery time of (218.57±50.00) minutes and intraoperative blood loss of (864.29±332.97) ml, 2 patients developed delayed hematoma and recovered well finally after emergency surgery, the follow-up time was 3 to 36 months, after separation surgery, the pain was significantly relieved, and neurological function recovered well in the patients. Three months after treatment, the VAS in the separation surgery group (1.43±0.76) scores was significantly lower than that in the conservative treatment group (8.64±0.51) scores (P<0.05);and the Frankel grades, Karnofsky scores, and QOL scores in the separation surgery group were significantly better than those in the conservative treatment group(P<0.05). CONCLUSION For patients with obvious neurological symptoms of spinal metastases, separation surgery not only can rapidly relieve nerve compression but also carry relatively low surgical risks, and improve the quality of life of patients.

Objective:To analyze the hepatobiliary phase (HBP) image manifestation classification and pathological features of nodules in nodules accompanied by hepatocellular carcinoma (NIN-HCC).Methods:Twenty-five cases cases (27 lesions) with cirrhosis who were confirmed as NIN-HCC by surgical pathology and underwent gadoxetate disodium-enhanced MRI examination before surgery at Nantong Third Hospital affiliated with Nantong University from July 2015 to November 2022 were retrospectively enrolled. The size, signal intensity, enhancement pattern, and pathological features of internal and external nodules were analyzed in NIN-HCC. The lesions score were recorded according to the 2018 version of the Liver Imaging Reporting and Data Systems (LI-RADS) classification criteria. NIN-HCCs were grouped and typed according to the different HBP signal intensities of the inner and outer nodules. The independent-samples t-test, Mann-Whitney U test or Fisher's exact probability method were used to compare the differences in imaging features and LI-RADS scores between the groups. The Spearman correlation coefficient was used to evaluate the correlation between the pathological differentiation degree of internal and external nodules and the HBP signal intensity. The Kaplan-Meier curve was used to analyze recurrence-free survival (RFS) following NIN-HCC surgery. Results:The internal nodules of the 27 NIN-HCCs showed altered hypervascularity with a maximum diameter of (13.2±5.5) mm during the arterial phase. 51.9% (14/27) and 48.1% (13/27) showed "fast in and fast out" and fast in and slow out"enhancement patterns. The external nodules showed altered hypovascularity with a maximum diameter of (25.7±7.3) mm, and 13 (48.1%) of them were accompanied to manifest during the arterial phase. NIN-HCC was divided into two groups according to the signal intensity of HBP of the outer nodules with the background liver parenchyma signal intensity as a reference: the hyposignal group ( n=17, 63.0%) and the isosignal group ( n=10, 37.0%). The hyposignal group and the isosignal group were divided into A~C type and D~F type, a total of six types, according to the hypo, iso, and hyper signals of the inner nodules and the signal intensity of the outer nodules as a reference. Within the hyposignal group, 7.4% (2/27) of the inner nodules showed hyposignal (type A), 37.0% (10/27) showed isosignal (type B), and 18.5% (5/27) showed hypersignal (type C). Within the isosignal group, 29.6% (8/27) of the inner nodules showed hyposignal (type D), 7.4% (2/27) showed isosignal (type E), and there was no hypersignal (type F). 40.7% (11/27) of the lesions were LR-4 in LI-RADS score, and 59.3% (16/27) were LR-5. There was no statistically significant difference ( P>0.05) in the maximum diameter, enhancement pattern, and LI-RADS score of internal and external nodules between the hypo and iso signal group. Histologically, NIN-HCC showed fine trabecular/pseudoglandular duct type without microvascular invasion, among which the inner nodules were mainly moderately differentiated HCC, and the outer nodules were mainly well-differentiated HCC. The degree of differentiation between the inner and outer nodules and the HBP signal intensity had no statistically significant difference ( r=0.290, P=0.143; r=0.079, P=0.697). The median RFS follow-up time after NIN-HCC radical resection was 31.7 months, and the cumulative RFS rates at 1, 3, and 5 years were 96.0%, 76.0%, and 64.0%, respectively. Conclusions:NIN-HCC can serve as a morphological marker for early-stage diagnosis of multi-step cancer evolution in HCC, with certain imaging and pathological features. HBP imaging classification is helpful to enhance the diagnostic recognition of this disease.

Objective To explore the efficacy of camrelizumab injection combined with transcatheter arterial chemoembolization(TACE)in the treatment of patients with primary liver cancer.Methods Patients with primary liver cancer were retrospectively studied and divided into control group and treatment group according to different treatment regimens.The control group was treated with TACE,while the treatment group was intravenously injected with 200 mg of camrelizumab injection once every 3 weeks on the 3rd day-7th day after first TACE on the basis of treatment in control group.All patients were treated for 12 weeks.The efficacy[objective response rate(ORR),disease control rate(DCR)],liver function[total bilirubin(TBil),glutamic oxalacetic transaminase(GOT),glutamic pyruvic transaminase(GPT)],serum tumor-related markers[alpha fetoprotein(AFP),hepatocyte growth factor(HGF),intercellular adhesion moleclar-1(ICAM-1)],T lymphocyte subsets(CD4+/CD8+ratio)and the safety was evaluated.Results There were 38 cases in treatment group and 42 cases in control group.After treatment,the ORR in treatment group and control group were 65.79％(25 cases/38 cases)and 42.86％(18 cases/42 cases),the DCR were 89.47％(34 cases/38 cases)and 71.43％(30 cases/42 cases),the differences were statistically significant(all P＜0.05).After treatment,serum TBil levels in treatment group and control group were(18.34±5.52)and(21.03±6.32)μmol·L-1;GOT levels were(54.79±17.07)and(60.57±18.29)U·L-1;GPT levels were(47.23±6.15)and(54.48±7.68)U·L-1;serum AFP levels were(96.94±28.17)and(152.49±41.22)ng·mL-1;HGF levels were(75.08±8.26)and(90.17±9.03)ng·mL-1;ICAM-1 levels were(432.38±131.43)and(526.15±184.36)ng·mL-1,respectively;CD4+/CD8+ratios were 1.31±0.23 and 1.16±0.21,respectively(all P＜0.05).Compared with the control group,the above indexes in treatment group were statistically significant(all P＜0.05).The adverse drug reactions in the treatment group were mainly reactive cutaneous capillary hyperplasia,gastrointestinal reaction and hand-foot syndrome,while the adverse drug reactions in the control group were mainly hand-foot syndrome and gastrointestinal reaction.The incidence of reactive cutaneous capillary hyperplasia in test group and control group was 52.63％and 0,the difference was statistically significant(P＜0.05).Conclusion Camrelizumab injection combined with TACE has significant efficacy in the treatment of patients with primary liver cancer.It can effectively reduce the levels of serum AFP,HGF and ICAM-1,and improve the immune function.

AP2 transcription factors belong to the AP2/ERF superfamily and are involved in the regula-tion of various biological processes in plant growth and development,as well as in response to biotic and abiotic stresses.However,studies on the AP2 transcription factor family of Perilla frutescens have not been reported.In this study,totally 18 AP2 family members were identified from the Perilla frutescens ge-nome and analyzed for gene structure,conserved motifs,and cis-acting elements using bioinformatics.WRINKLED1(WRI1)is a key regulator of lipid biosynthesis in many plant species and plays an impor-tant role in the regulation of lipid synthesis.Sequence comparison revealed that one member of WRI1 is highly homologous to AtWRI1 and contains two conserved AP2 domains,named PfWRI1.The expression levels of PfAP2 family genes were analyzed in different tissues of Perilla frutescens and at different stages of seed development in conjunction with the transcriptome data,and the results showed that PfWRI1 is highly expressed only in the seeds of Perilla frutescens,suggesting that PfWRI1 may be related to the de-velopmental process of the seeds.The overexpression vector of plant pCAMBIA1303-PfWRI1 was con-structed,and wild-type(Col)and mutant(wri1-1)Arabidopsis thaliana were transformed by Agrobacte-rium tumefaciens to obtain overexpression and complementation lines,respectively.The results showed that the expression of P fWRI1 led to an increase in oil content of Arabidopsis seeds by 8.90％-13.57％compared with Col,and promoted the accumulation of oleic acid(C18:1)and linoleic acid(18:2)and reduced the accumulation of palmitic acid(C16:0),arachidonic acid(C20:0),and cis-11-Eicosenoic acid(C20:1)in transgenic Arabidopsis seeds.In addition,PfWRI1 gene expression increased the ex-pression of glycolysis and fatty acid biosynthesis-related genes AtPKP-α,AtPKP-β1,AtBCCP2,AtSUS2,and AtLIP1.Taken together,PfWRI1 may promote lipid accumulation by increasing unsaturated fatty acid content through interaction with the above genes.

Perilla frutescens,a short-day plant,is rich in biologically active substances and nutrients.Current research on Perilla frutescens focuses on agronomic traits such as yield and fatty acid accumula-tion,with limited exploration of the flowering process and floral organ development.The molecular regu-latory mechanisms underlying these aspects remain unclear.FLOWERING LOUC T(FT)is a florigen in Arabidopsis,plays critical roles in floral transition.PfFT3 is unannotated by genome but annotated by transcriptomics data to the FT-like subfamily.Its function in controlling flowering is yet to be explored.Here subcellular localization analysis showed that PfFT3 is localized in the nucleus and cytoplasm.The plant over-expression vector pCAMBIAI1303-PfFT3 was constructed and transformed into wild-type(Col-0)and mutant fd-2,fd-3,and ft-10 plants by agrobacterium-mediated inflorescence infiltration as a means of obtaining genetically stable and pure overexpression and backfill transgenic lines in Arabidopsis,respectively.Analysis of the results showed that overexpression of PfFT3 significantly promoted early flowering in Arabidopsis and rescued the late-flowering phenotype of the mutants fd-2,fd-3,and ft-10,and that expression of the exogenous PfFT3 promoted the expression of the downstream endogenous flow-ering genes AtSOC1,AtAP1,AtFUL,and AtLFY.This study demonstrates the positive role of PfFT3 in promoting flowering,providing a foundation for further investigation of PfPEBP function and advancing the breeding of early-flowering Perilla frrutescens cultivars.

Transcatheter aortic valve replacement(TAVR)has emerged as a promising therapeutic alternative for addressing aortic valve-related pathologies.However,the occurrence of rapid arrhythmias linked to TAVR procedures is progressively drawing scrutiny.Presently,pharmacologic interventions constitute the mainstay of managing atrial arrhythmias related to TAVR,while the potential of ablation as a viable treatment modality remains undefined.Notably,in cases where the arrhythmia's genesis is presumed to be intricately linked to the prosthetic valve,the practicality and safety of ablation procedures remain unverified.Our institution has successfully ventured into radiofrequency ablation for a distinctive patient presenting with this intricate condition,thereby tentatively affirming the efficacy and safety of catheter ablation administered on the surface of prosthetic valves.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

H 1-antihistamines are widely used in the treatment of various allergic diseases, but there are still many challenges in the safe and rational use of H 1-antihistamines in pediatrics, and there is a lack of guidance on the prescription review of H 1-antihistamines for children.In this paper, suggestions are put forward from the indications, dosage, route of administration, pathophysiological characteristics of children with individual difference and drug interactions, so as to provide reference for clinicians and pharmacists.

Platelets are reprogrammed by cancer via a process called education, which favors cancer development. The transcriptional profile of tumor-educated platelets (TEPs) is skewed and therefore practicable for cancer detection. This intercontinental, hospital-based, diagnostic study included 761 treatment-naïve inpatients with histologically confirmed adnexal masses and 167 healthy controls from nine medical centers (China, n = 3; Netherlands, n = 5; Poland, n = 1) between September 2016 and May 2019. The main outcomes were the performance of TEPs and their combination with CA125 in two Chinese (VC1 and VC2) and the European (VC3) validation cohorts collectively and independently. Exploratory outcome was the value of TEPs in public pan-cancer platelet transcriptome datasets. The AUCs for TEPs in the combined validation cohort, VC1, VC2, and VC3 were 0.918 (95% CI 0.889-0.948), 0.923 (0.855-0.990), 0.918 (0.872-0.963), and 0.887 (0.813-0.960), respectively. Combination of TEPs and CA125 demonstrated an AUC of 0.922 (0.889-0.955) in the combined validation cohort; 0.955 (0.912-0.997) in VC1; 0.939 (0.901-0.977) in VC2; 0.917 (0.824-1.000) in VC3. For subgroup analysis, TEPs exhibited an AUC of 0.858, 0.859, and 0.920 to detect early-stage, borderline, non-epithelial diseases and 0.899 to discriminate ovarian cancer from endometriosis. TEPs had robustness, compatibility, and universality for preoperative diagnosis of ovarian cancer since it withstood validations in populations of different ethnicities, heterogeneous histological subtypes, and early-stage ovarian cancer. However, these observations warrant prospective validations in a larger population before clinical utilities.

Objective To evaluate extrathyroidal extension (ETE) in papillary thyroid microcarcinoma (PTMC) with three-dimensional tomographic ultrasound imaging (3D-TUI). Methods A total of 97 thyroid nodules of 79 patients with PTMC treated in PUMC Hospital from February 2016 to January 2018 were included in this study.Two ultrasound experts performed independent blinded assessment of the relationship between thyroid nodules and thyroid capsule by two-dimensional ultrasound (2D-US) and 3D-TUI.The results of 2D-US and 3D-TUI in evaluating ETE were compared with intraoperative findings and postoperative histological and pathological results. Results Among the 97 nodules,54 (55.7%) nodules had ETE.The diagnostic sensitivity (68.5% vs.37.0%;χ²=10.737,P=0.002),accuracy (74.5% vs.56.7%;χ²=6.686,P=0.015),and area under the receiver operating characteristic curve[0.761 (95%CI=0.677-0.845) vs.0.592 (95%CI=0.504-0.680);Z=3.500,P<0.001] of 3D-TUI were higher than those of 2D-US.However,3D-TUI and 2D-US showed no significant difference in the specificity (84.1% vs.81.4%;χ²=0.081,P=0.776),negative predictive value (67.9% vs.50.7%;χ²=3.645,P=0.066),or positive predictive value (84.1% vs.71.4%;χ²=1.663,P=0.240). Conclusion Compared with 2D-US,3D-TUI demonstrates increased diagnostic efficiency for ETE of PTMC.
