ObjectiveTo explore the effect of gypenosides （GPs） on liver lipid deposition in metabolism-associated fatty liver disease （MAFLD） mice and its mechanism based on classical/non-classical ferroptosis. MethodsEight male C57BL/6 mice in a blank group and 32 male apolipoprotein E gene knockout （ApoE^-/-） mice were randomly divided into a model group， a low-dose GPs （GPs-L） group， a high-dose GPs （GPs-H） group， and a simvastatin （SV） group. Starting from the second week， mice in the blank group were given a maintenance diet， and the other four groups were fed a high-fat diet daily. After eight weeks of feeding， mice in the GPs-L and GPs-H groups were given GPs of 1.487 mg·kg^-1·d^-1 and 2.973 mg·kg^-1·d^-1， respectively， and mice in the SV group were given simvastatin of 2.275 mg·kg^-1·d^-1. Mice in the blank group and the model group were given saline of equal volume by gavage for four weeks. The content of total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL-C）， alanine aminotransferase （ALT）， and aspartate aminotransferase （AST） in the serum of mice in each group was detected by an automatic biochemical analyzer. The level of non-esterified fatty acid （NEFA） and TG in the mouse liver was measured by the kit. The change in liver tissue structure and lipid deposition was observed by hematoxylin-eosin （HE） and oil red O staining. The levels of coenzyme Q₁₀ （CoQ₁₀）， glutathione （GSH）， malondialdehyde （MDA）， and Fe²⁺ in serum， as well as nicotinamide adenine dinucleotide phosphate ［NAD（P）H］ in the liver were detected by enzyme-linked immunosorbent assay （ELISA）. The expression of ferroptosis suppressor protein 1 （FSP1） in the liver of mice was observed by the immunohistochemical （IHC） method， and the expression of genes and proteins related to classical and non-classical ferroptosis pathways was analyzed by real-time polymerase chain reaction （Real-time PCR） and Wes automated protein expression analysis system. ResultsCompared with those in the blank group， the levels of TC， TG， LDL-C， ALT， and AST in serum and TG and NEFA in the liver in the model group were significantly increased， and the level of HDL-C in serum was significantly decreased （P<0.01）. The liver tissue structure changed， and there were fat vacuoles of different sizes and a large number of red lipid droplets， with obvious lipid deposition. The level of CoQ10 and GSH in serum and NADH in the liver were significantly decreased， while the level of MDA and Fe²⁺ in serum was significantly increased （P<0.01）. The mRNA and protein expressions of cystine/glutamate transporter （xCT/SLC7A11）， glutathione peroxidase （GPX4）， p62， nuclear factor E₂-related factor 2 （Nrf2）， and FSP1 were significantly decreased， and the mRNA and protein expressions of tumor antigen （p53）， spermidine/spermine N1-acetyltransferase 1 （SAT1）， arachidonate 15-lipoxygenase （ALOX15）， and Kelch-like epichlorohydrin-associated protein-1 （Keap1） were significantly increased （P<0.01）. Compared with those in the model group， the level of TC， TG， LDL-C， ALT， and AST in serum and TG and NEFA in the liver of mice in the GPs-L， GPs-H， and SV groups were decreased， while the level of HDL-C in serum was significantly increased （P<0.05， P<0.01）. The liver tissue structure and lipid deposition were improved. The levels of CoQ10 and GSH in serum and NADH in the liver were significantly increased， while the levels of MDA and Fe²⁺ in serum were significantly decreased （P<0.05， P<0.01）. The mRNA and protein expressions of xCT， GPX4， p62， Nrf2， and FSP1 were significantly increased， while the mRNA and protein expressions of p53， SAT1， ALOX15， and Keap1 were significantly decreased （P<0.05， P<0.01）. ConclusionGPs can interfere with liver lipid deposition in MAFLD mice through classical/non-classical ferroptosis pathways.

The collection， screening， weighting， and comprehensive evaluation of indicators are key steps in establishing the effectiveness evaluation index system of traditional Chinese medicine （TCM）. This article systematically reviewed the research methods in different stages， explored their existing problems， and provide reflections and recommendations. For indicator collection， literature research and expert interviews are generally used， but patient participation is not sufficient； for indicator screening， the Delphi method is the most widely used method， but there is still a lack of criteria and evidence to support indicator screening， and a few studies have applied clinical investigation methods； for indicator weighting， including subjective weighting and objective weighting， but they are mostly the application of a single type of method， and the indicator weights lack reliability； for comprehensive evaluation， analytic hierarchy process， TOPSIS， fuzzy comprehensive evaluation， rank sum ratio， the fuzzy-hierarchy technique for order preference by similarity to an ideal solution， grey relational analysis， and data envelopment analysis have gradually been applied to the study of TCM effectiveness evaluation， however， they often reflect the short-term effectiveness of TCM and can not highlight their long-term effectiveness advantages. Therefore， it is necessary to strengthen the participation of patients and consider their perspectives； in the process of selecting indicators， evidence support for importance judgments should be provided to experts； in indicator weighting， we should integrate subjective and objective data information and actively carry out research on optimizing combination weighting methods； finally， a disease information management platform could be established and a dynamic comprehensive evaluation model could be constructed to provide new ideas and methods for evaluating the effectiveness of TCM.

ObjectiveTo investigate the clinicopathological features， diagnosis and treatment methods， and prognosis of gallbladder sarcomatoid carcinoma （GBSC）. MethodsA retrospective analysis was performed for the clinical data of 16 patients with GBSC who were admitted to The First Affiliated Hospital of Zhengzhou University from January 2015 to April 2023， including general information， clinical manifestations， imaging features， pathological features， and treatment modality， and follow-up was performed for all patients. The Kaplan-Meier method was used to perform the survival analysis and plot the survival curve， and the Log-rank test was used for comparison between groups. ResultsAmong the 16 patients， there were 6 male patients and 10 female patients， with a mean age of 62.9±8.4 years. The main clinical manifestations were right upper abdominal pain in 13 patients （81.3%）， nausea in 5 patients （31.3%）， abdominal distension in 4 patients （25.0%）， poor appetite in 3 patients （18.8%）， weakness in 2 patients （12.5%）， fever in 2 patients （12.5%）， and jaundice in 1 patient （6.3%）， and 3 patients were asymptomatic and were found to have this disease by physical examination. Of all patients， 81.3% （13/16） were in the advanced stage （stage Ⅲ/Ⅳ） at the time of initial diagnosis. Histopathological examination showed that some cancer cells were spindle-shaped under the microscope， with marked nuclear division and noticeable heteromorphism. Immunohistochemistry showed a positive expression rate of 100% （16/16） for Vimentin， AE1/AE3， and CK8/18， and Ki-67 proliferation index was highly expressed in 81.3% （13/16） of the patients （≥50%）， with a median of 70% （range 20%‍ ‍—‍ ‍90%）. All 16 patients underwent surgical treatment， with radical surgery in 11 patients and palliative surgery in 5 patients， among whom 9 received R0 resection， 2 received R1 resection， and 5 received R2 resection， and 7 patients received adjuvant therapy after surgery. Effective follow-up was achieved for all 16 patients， with a follow-up time of 0.5‍ ‍—‍ ‍26.0 months and a median follow-up time of 11.0 months. By the end of follow-up， 2 patients survived and 14 patients died due to tumor recurrence or metastasis， with a median survival time of 10.0 months， and the 1- and 2-year cumulative survival rates after surgery were 31.3% and 8.3%， respectively. The prognostic analysis showed that TNM stage （χ²=6.727， P=0.009）， surgical approach （χ²=7.508， P=0.006）， margin condition （χ²=7.934， P=0.005）， and adjuvant therapy （χ²=4.608， P=0.032） were associated with the prognosis of patients. ConclusionThe clinical manifestations of GBSC lack specificity， and a confirmed diagnosis relies on immunohistochemical analysis. Most patients are in the advanced disease at the time of initial diagnosis and tend to have a poor prognosis. There are currently no targeted therapies for this disease， and radical surgery with negative margins and adjuvant therapy can improve the survival rate of patients.

OBJECTIVE To study the effects of methimazole on the urinary metabolomics of hyperthyroidism rats， and to preliminarily investigate its possible mechanism. METHODS Thirty SD rats were randomly divided into control group， model group and methimazole group， with 10 rats in each group. Except for the control group， the rats in the other two groups were given Levothyroxine sodium tablets 160 mg/kg by intragastric administration for 15 days； at the same time， methimazole group was additionally given methimazole 3.6 mg/kg daily by intragastric administration every day. The basic condition of the rats was observed， and the body weight and anal temperature were measured. After the last medication， the serum levels of triiodothyronine （T3）， tetraiodothyronine （T4）， free triiodothyronine （FT3）， free tetraiodothyronine （FT4）， and thyroid stimulating hormone （TSH） were determined； 24-hour urine was collected on the 15th day after administration. UPLC-TOF-MS was used to analyze the urine metabolomics of rats. Principal component analysis and orthogonal partial least squares-discriminant analysis were used to screen out related differential metabolites， and potential metabolic pathways were analyzed by using HMDB and KEGG. RESULTS Compared with the control group， the rectal temperature， serum levels of T3， T4， FT3 and FT4， the expressions of differential metabolites sebacic acid， cholic acid 3-O-glucuronic acid and N6， N6， N6-trimethyl-L-lysine in urine were significantly up-regulated， while body weight， serum level of TSH， the expressions of deoxycytidine and 2-oxo-4-methylthiobutanoic acid in urine were significantly down-regulated （P＜0.01）. Compared with model group， above indexes of rats were reversed significantly in methimazole group （P＜0.01 or P＜0.05）. Above five differential metabolites were mainly involved in four signaling pathways: pentose and glucuronate interaction， lysine degradation， cysteine and methionine metabolism， and pyrimidine metabolism. CONCLUSIONS Methimazole might improve hyperthyroidism by modulating the four pathways of pentose and glucuronate interaction， lysine degradation， cysteine and methionine metabolism， and pyrimidine metabolism.

Myelodysplastic syndrome (MDS) is a malignant hematologic tumor, which is currently difficult to cure. The theory of Xuanfu was proposed by Liu Wansu, which is unique in the clinical evidence of Chinese medicine and is less frequently applied to hematological diseases. The application of Xuanfu theory in myelodysplastic syndrome provides new ideas for the treatment of the disease. The abnormal flow of Qi, blood and fluids caused by the occlusion of the Xuanfu is the cause of toxic stasis obstruction, which is the pathogenesis of toxic stasis obstruction. Thus, the method of dispersion of Bone from Xuanfu, the external treatment of Xuanfu, and regulation of liver qi and Xuanfu help to return to normal of opening and closing function of Xuanfu, and release toxic stasis. In this paper, we analyzed the evidence of toxin-stasis obstruction in myelodysplastic syndrome from the theory of Xuanfu, aiming to provide a feasible theoretical basis for clinical treatment of the disease.

Objective To investigate the association between intraoperative hypotension and post-operative acute kidney injury(AKI)in patients undergoing brain tumor resections.Methods A total of 428 patients undergoing elective craniotomy for tumor resection were selected,276 males and 152 females,aged≥18 years,BMI 15-36 kg/m2,ASA physical statusⅡ orⅢ.Based on postoperative occurrence of AKI,the patients were divided into two groups:the AKI group and the control group.This study defined three thresholds for hypotension,including MAP during surgery below 65 mmHg,60 mmHg,and 55 mmHg.Multivariate logistic regression was used to analyze the correlation between intraoperative hypotension and postoperative AKI under three thresholds.Results A total of 107 patients had postoperative AKI.The re-sults of multivariable regression analysis indicated that intraoperative MAP＜65 mmHg(OR = 1.11,95%CI 1.03-1.20,P = 0.010)and intraoperative MAP＜60 mmHg(OR = 1.12,95%CI 1.02-1.23,P = 0.017)were associated with postoperative AKI.Conclusion Intraoperative MAP＜65 mmHg or 60 mmHg is associated with postoperative AKI in patients undergoing brain tumor resection.

Objective To investigate the risk factors of in-hospital mortality and establish a risk prediction model for patients receiving venoarterial extracorporeal membrane oxygenation(VA-ECMO).Methods We retrospectively collected the data of 302 patients receiving VA-ECMO in ICU of 3 hospitals in Guangdong Province between January,2015 and January,2022 using a convenience sampling method.The patients were divided into a derivation cohort(201 cases)and a validation cohort(101 cases).Univariate and multivariate logistic regression analyses were used to analyze the risk factors for in-hospital death of these patients,based on which a risk prediction model was established in the form of a nomogram.The receiver operator characteristic(ROC)curve,calibration curve and clinical decision curve were used to evaluate the discrimination ability,calibration and clinical validity of this model.Results The in-hospital mortality risk prediction model was established based the risk factors including hypertension(OR=3.694,95%CI:1.582-8.621),continuous renal replacement therapy(OR=9.661,95%CI:4.103-22.745),elevated Na2+ level(OR=1.048,95%CI:1.003-1.095)and increased hemoglobin level(OR=0.987,95%CI:0.977-0.998).In the derivation cohort,the area under the ROC curve(AUC)of this model was 0.829(95%CI:0.770-0.889),greater than those of the 4 single factors(all AUC<0.800),APACHE Ⅱ Score(AUC=0.777,95%CI:0.714-0.840)and the SOFA Score(AUC=0.721,95%CI:0.647-0.796).The results of internal validation showed that the AUC of the model was 0.774(95%CI:0.679-0.869),and the goodness of fit test showed a good fitting of this model(χ2=4.629,P>0.05).Conclusion The risk prediction model for in-hospital mortality of patients on VA-ECMO has good differentiation,calibration and clinical effectiveness and outperforms the commonly used disease severity scoring system,and thus can be used for assessing disease severity and prognostic risk level in critically ill patients.
