Objective To investigate the safety, economic benefits and psychological effects of day breast conserving surgery for breast cancer. Methods The demographic data and clinical data of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgeries in West China Hospital of Sichuan University from March 2020 to June 2021 were retrospectively collected; the demographic data, clinical data, medical and related transportation costs, and preoperative and postoperative BREAST-Q scores of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgery in West China Hospital of Sichuan University from June 2021 to June 2022 were prospectively collected. The safety, economic benefit, and psychological satisfaction of day surgery was analyzed. Results A total of 42 women with breast cancer were included in the retrospective study and 39 women with breast cancer were included in the prospective study. In both prospective and retrospective studies, the mean age of patients in both groups were <50 years. There were only statistical differences between the two groups in the aspects of hypertension (P=0.022), neoadjuvant chemotherapy (P=0.037) and postoperative pathological estrogen receptor (P=0.033) in the prospective study. In postoperative complications, there were no statistical differences in the surgical-related complications or anesthesia-related complications between the two groups in either the prospective study or the retrospective study (P>0.05). In terms of the overall cost, we found that the day surgery group was more economical than the ward surgery group in the prospective study (P=0.002). There were no statistical differences in postoperative psychosocical well-being, sexual well-being, satisfaction with breasts or chest condition between the two groups (P>0.05). Conclusion It is safe and reliable to carry out breast conserving surgery in day surgery center under strict management standards, which can save medical costs and will not cause great psychological burden to patients.

Objective To evaluate efficacy and safety of 5 different Chinese herbal decoctions in the treatment of rheumatoid arthritis(RA)by network Meta-analysis.Methods PubMed,Embase,Cochrane Library and Web of Science,CNKI,WanFang Data and VIP databases were electronically searched to collect randomized controlled trials(RCTs)of 5 kinds of traditional Chinese medicine decoctions(Juanbi decoction,Wutou decoction,Baihu plus Guizhi decoction,Guizhi Shaoyao Zhimu decoction and Duhuo Jisheng decoction)combined with conventional treatment such as methotrexate and meloxicam from inception to January 1,2024.Two reviewers independently screened literature,extracted data and assessed risk bias of included studies.The network Meta-analysis was then performed using Stata 17 software.Results A total of 35 RCTs involving 3 316 patients were included.The results of the network Meta-analysis found that compared with conventional treatment,5 kinds of traditional Chinese medicine decoction+conventional treatment significantly increased total clinical effective rate(P＜0.05);Juanbi decoction+conventional treatment,Guizhi Shaoyao Zhimu decoction+conventional treatment,Duhuo Jisheng decoction+conventional treatment significantly reduced RF level(P＜0.05);Juanbi decoction+conventional treatment,Wutou decoction+conventional treatment,Guizhi Shaoyao Zhimu decoction+conventional treatment,Duhuo Jisheng decoction+conventional treatment significantly reduced CRP level and ESR level(P＜0.05);Guizhi Shaoyao Zhimu decoction+conventional treatment,Duhuo Jisheng decoction+conventional treatment significantly reduced incidence of adverse reactions(P＜0.05).The cumulative probability ranking results showed that Guizhi Shaoyao Zhimu decoction+conventional treatment had the best effect in improving the total clinical effective rate and reducing RF level and incidence of adverse reactions;Wutou decoction+conventional treatment had the best effect in reducing CRP level;Juanbi decoction+conventional treatment had the best effect in reducing ESR level.Conclusion Traditional Chinese medicine decoction combined with conventional treatment can improve the overall efficacy of RA.In terms of improving indexes,Guizhi Shaoyao Zhimu Decoction or Juanbi decoction combined with conventional treatment can be selected for clinical treatment of RA.Guizhi Shaoyao Zhimu decoction or Duhuo Jisheng decoction combined with conventional therapy can be selected to improve safety.Due to the limited quantity and quality of the included studies,more high-quality studies are needed to verify the above conclusion.

Objectives:To analyze the correction of postoperative coronal imbalance in adult degenerative scoliosis patients undergoing spinal fusion surgery,and to explore the impact of leveling of the most tilted vertebra(L4 or L5)in the lumbosacral curve on the correction of coronal imbalance.Methods:A retrospective analysis was conducted on 61 patients(17 male and 44 female;aged 51 to 78 years,mean 63.57±8.41 years;body mass index 15.79-35.55kg/m2,mean 25.83±3.69kg/m2)who underwent degenerative scoliosis correction surgery between January 2019 and March 2023 in Tianjin Union Medical Center.The patients were catego-rized based on the Obeid classification and the length of fusion segments into concave long segment group(17 cases),concave short segment group(15 cases),convex long segment group(15 cases),and convex short seg-ment group(14 cases).Coronal radiographic parameters[Cobb angle,coronal balance distance(CBD),coronal tilt angle]and sagittal radiographic parameters(sagittal vertical axis,thoracic kyphosis,lumbar lordosis,pelvic inci-dence,pelvic tilt,sacral slope)were measured on full spine anteroposterior and lateral X-rays preoperatively and on 3d postoperatively.The postoperative coronal and sagittal imbalance corrections were compared be-tween groups.Pearson correlation analysis was performed to investigate the relationship between the correction ratio of the maximal coronal tilt angle in the lumbosacral curve(L4 or L5)and postoperative CBD.The opera-tive time,blood loss,and visual analogue scale(VAS)pre-and postoperatively were compared between the four groups.Results:The postoperative coronal Cobb angle,CBD,and maximal coronal tilt angle at L4 or L5 of the concave long segment group,convex long segment group,and convex short segment group were statisti-cally different from those before operation(P＜0.05).In the concave short segment group,the postoperative coronal Cobb angle and maximal coronal tilt angle at L4 or L5 were significantly different from those before operation(P＜0.05),while no significant difference was found between pre-and postoperative CBD(P=0.085).Pearson correlation analysis revealed a significant negative correlation(r=-0.570,P＜0.01)between postoperative CBD and coronal tilt correction ratio in the convex group,with the linear regression equation being postoper-ative CBD=32.81-28.38 x coronal tilt correction ratio.When the correction ratio of the maximal coronal tilt angle at L4 or L5 exceeding 45％in convex coronal malalignment patients,it's predicted that the CBD could be corrected to within 20mm.No significant correlation was found between postoperative CBD and the coronal tilt correction ratio in the concave group(r=0.098,P=0.59).Patients in both the convex and concave short segment groups had shorter operative time and less blood loss than long segment groups.Postoperative VAS scores improved significantly in all groups(P＜0.05).Conclusions:In adult degenerative scoliosis patients with convex coronal malalignment,both short and long segment fusions are capable of correcting coronal imbalance.Concave coronal malalignment patients require long segment fusion for the correction of coronal imbalance.To achieve optimal coronal balance in convex coronal malalignment patients,a correction ratio of the maximal coronal tilt angle at L4 or L5 shall exceed 45％.

To report a case with hereditary spastic paraplegia type 11(SPG11)in association with typical thin corpus callosum(TCC)and"Ears-of-the-lynx sign"on MRI imaging.The patient was a 13-year-old boy.The main symptoms are walking instability and falling easily.Over the period of one year,the symptoms gradually progressed when accompanied by poor handwriting and a decrease in learning ability.The parents are not related.Brain MRI shows a thin corpus callosum,and high symmetric signals in the anterior horn of the lateral ventricles on T2 and Flair sequence.WES detected two heterozygous mutations in the SPG11 gene,NM_025137:c.2073delT and c.257+5G>A,respectively from the parents.The proband was finally diagnosed with SPG11.Brain MRI found that TCC and"lynx ear sign"are highly sensitive and specific for the diagnosis of SPG11.The patients with spastic paraplegia should be considered the possibility of SPG11.

Objective: To establish a novel classification system for predicting the risk of intraoperative neurophysiological monitoring (IONM) events in surgically-treated patients with kyphotic deformity. Methods: Patients with kyphotic deformity who underwent surgical correction of cervicothoracic, thoracic, or thoracolumbar kyphosis in our center from July 2005 to December 2020 were recruited. We proposed a classification system to describe the morphology of the spinal cord on T2-weighted sagittal magnetic resonance imaging: type A, circular/symmetric cord with visible cerebrospinal fluid (CSF) between the cord and vertebral body; type B, circular/oval/symmetric cord with no visible CSF between the cord and vertebral body; type C, spinal cord that is fattened/deformed by the vertebral body, with no visible CSF between the cord and vertebral body. Furthermore, based on type C, the spinal cord compression ratio (CR) < 50% was defined as the subtype C-, while the spinal cord CR ≥ 50% was defined as the subtype C+. IONM event was documented, and a comparative analysis was made to evaluate the prevalence of IONM events among patients with diverse spinal cord types. Results: A total of 294 patients were reviewed, including 73 in type A; 153 in type B; 53 in subtype C- and 15 in subtype C+. Lower extremity transcranial motor-evoked potentials and/or somatosensory evoked potentials were lost intraoperatively in 41 cases (13.9%), among which 4 patients with type C showed no return of spinal cord monitoring data. The 14 subtype C+ patients (93.3%) had IONM events. Univariate logistic regression analysis showed that patients with a type C spinal cord (subtype C-: odds ratio [OR], 10.390; 95% confidence interval [CI], 2.215–48.735; p = 0.003; subtype C+, OR, 497.000; 95% CI, 42.126– 5,863.611; p < 0.001) are at significantly higher risk of a positive IONM event during deformity correction compared to those with a type A. In further multiple logistic regression analysis, the spinal cord classification (OR, 5.371; 95% CI, 2.966–9.727; p < 0.001) was confirmed as an independent risk factor for IONM events. Conclusion We presented a new spinal cord classification system based on the relative position of the spinal cord and vertebrae to predict the risk of IONM events in patients with kyphotic deformity. In patients with type C spinal cord, especially those in C+ cases, it is essential to be aware of potential IONM events, and adopt standard operating procedures to facilitate neurological recovery.

Pien Tze Huang(PZH),a class-1 nationally protected traditional Chinese medicine(TCM),has been used to treat liver diseases such as hepatitis;however,the effect of PZH on the progression of sepsis is un-known.Here,we reported that PZH attenuated lipopolysaccharide(LPS)-induced sepsis in mice and reduced LPS-induced production of proinflammatory cytokines in macrophages by inhibiting the acti-vation of mitogen-activated protein kinase(MAPK)and nuclear factor-kappa B(NF-κB)signalling.Mechanistically,PZH stimulated signal transducer and activator of transcription 3(STAT3)phosphory-lation to induce the expression of A20,which could inhibit the activation of NF-κB and MAPK signalling.Knockdown of the bile acid(BA)receptor G protein-coupled bile acid receptor 1(TGR5)in macrophages abolished the effects of PZH on STAT3 phosphorylation and A20 induction,as well as the LPS-induced inflammatory response,suggesting that BAs in PZH may mediate its anti-inflammatory effects by acti-vating TGR5.Consistently,deprivation of BAs in PZH by cholestyramine resin reduced the effects of PZH on the expression of phosphorylated-STAT3 and A20,the activation of NF-κB and MAPK signalling,and the production of proinflammatory cytokines,whereas the addition of BAs to cholestyramine resin-treated PZH partially restored the inhibitory effects on the production of proinflammatory cytokines.Overall,our study identifies BAs as the effective components in PZH that activate TGR5-STAT3-A20 signalling to ameliorate LPS-induced sepsis.

Objective:To explore the predictive value of 18F-FDG PET/CT in molecular subtyping of triple-negative breast cancer. Methods:A retrospective analysis was performed on the clinical and imaging data of 227 breast cancer patients who underwent 18F-FDG PET/CT examination in the Tianjin Medical University Cancer Institute & Hospital from January 1, 2010 to December 31, 2022. Based on the expression levels of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2) in the primary breast cancer, the patients were categorized into two groups: triple-negative breast cancer (TNBC) and non-TNBC. Radiomic features were extracted from images of both groups, and a radiomic model was constructed to predict the molecular subtype of the TNBC groups. In addition, the clinical data, CT morphological features, and PET metabolic parameters of both groups were compared to determine the indicators with statistically significant differences and develop a comprehensive radiomic model combined with clinical characteristics. Results:Compared to the non-TNBC group, the TNBC groups exhibited more significant invasiveness in terms of tumor diameter, margins, ipsilateral axillary lymph node metastasis, invasion of neighboring skin or papillae, and PET metabolic parameters ( t = -3.19; χ2 = 7.30, 8.10, 5.34; t = 3.80, 3.30, 3.42, P < 0.05). The constructed 18F-FDG PET/CT radiomic model proved effective in predicting the molecular subtype of the TNBC group, and the receiver operating characteristic (ROC) curve showed an area under the curve (AUC) of 0.83 (95% CI 0.78-0.88), an accuracy of 75.9%, a sensitivity of 74.5%, and a specificity of 77.2%. In contrast, the constructed comprehensive radiomic model displayed an AUC of 0.86 (95% CI 0.81-0.90), an accuracy of 77.2%, a sensitivity of 78.6%, and a specificity of 75.9%. Conclusions:18F-FDG PET/CT plays an important role in predicting molecular subtypes of TNBC. The constructed radiomic model and comprehensive radiomic model can further enhance the prediction efficacy of PET metabolic parameters and accelerate the development of accurate treatment protocols in clinical practice, thus improving the prognosis of breast cancer.

Objective To evaluate the differential diagnostic value of synthetic magnetic resonance imaging(syMRI)and field of view optimized and constrained undistorted single shot diffusion weighted imaging(FOCUS DWI)in patient with breast imaging reporting and data system(BI-RADS)4 breast lesions.Methods A total of 68 patients who underwent breast MRI and were classified as BI-RADS category 4 were prospectively enrolled.Among them,there were 31 cases of benign lesions(benign group)and 37 cases of malignant lesions(malignant group).All patients underwent T1WI,T2WI,FOCUS DWI,dynamic contrast-enhanced magnetic resonance ima-ging(DCE-MRI)and syMRI.Two radiologists delineated the region of interest(ROI)on quantitative parameters images of syMRI and the apparent diffusion coefficient(ADC)images generated from FOCUS DWI and calculated T1,T2,proton density(PD)and ADC values,respectively.The thresholds and diagnostic efficacy of syMRI and FOCUS DWI parameters were evaluated by the receiver op-erating characteristic(ROC)curve.Logistic regression analysis was used to combine the parameters of the two sequences and evalu-ate the diagnostic efficacy.Results The T2,PD,and ADC values in the malignant group were significantly lower than those in the benign group(P＜0.05),but there were no statistically significant difference in T1 values between the groups(P＞0.05).T2 and ADC values could be used as important diagnostic indexes in patient with malignant lesions of BI-RADS 4 breast lesions,and the area under the curve(AUC)of T2 and ADC was 0.833 and 0.867,respec-tively.There was no significant difference in AUC of T2 and ADC between benign and malignant groups(Z=0.485,P=0.627).The AUC of T2 value combined with ADC value was 0.910,and the sensitivity and specificity was 90.3％and 89.2％,respectively.Conclusion T2 value of syMRI and ADC value of FOCUS DWI can be used as quantitative diagnostic indicators in patients with BI-RADS 4 breast lesions.The combination of T2 and ADC values can further improve the differential diagnosis efficiency.
