OBJECTIVE To investigate the effects and mechanisms of Buyang huanwu decoction （BYHWD） and its active fractions in ameliorating non-alcoholic fatty liver disease. METHODS BYHWD and its effective fractions obtained through ethanol precipitation， as well as 30% ethanol， 50% ethanol， and 75% ethanol fractions （namely， the CC effective fraction， 30YC effective fraction， 50YC effective fraction， and 75YC effective fraction）， were prepared. These preparations were administered to rats via intragastric administration to prepare corresponding drug-containing serum （blank serum and simvastatin-containing serum were prepared using the same protocol）. Human L02 hepatocytes were divided into control group， model group， simvastatin-containing serum group， BYHWD-containing serum group， CC-containing serum group， 30YC-containing serum group， 50YC-containing serum group， and 75YC-containing serum group. Except for the control group， other groups were given 0.2 mol/L oleic acid for 24 h to induce a lipid accumulation model， and then intervened with 20% drug-containing serum/blank serum for 24 h. The lipid deposition in cells was observed， and the proportion of lipid droplet area was calculated； the levels of triglycerides （TG） and indicators of oxidative stress [malondialdehyde （MDA）， superoxide dismutase （SOD）] as well as liver function [alanine amino- transferase （ALT）， aspartate amino-transferase （AST）] in cells were detected； protein and mRNA expressions of AMP-activated protein kinase （AMPK）/sterol regulatory element-binding protein-1 （SREBP-1）/glycerol-3-phosphate acyltransferase （GPAT） signaling pathway were also measured. RESULTS Compared with the control group， cells in the model group exhibited severe cellular steatosis， with a significantly increased proportion of lipid droplet area， as well as the elevated levels of TG， ALT， AST， and MDA in cells， along with significantly up-regulated mRNA and protein expression levels of SREBP-1 and GPAT （P＜0.05）. The level of SOD， mRNA expression of AMPK， as well as the protein phosphorylation level of AMPK were decreased significantly （P＜0.05）. Compared with the model group， cellular steatosis was alleviated in all drug-containing serum groups， and the levels of most of the aforementioned quantitative indicators were significantly reversed （P＜0.05）. CONCLUSIONS BYHWD and its active fractions can exert a therapeutic effect on improving non-alcoholic fatty liver disease by regulating the AMPK/SREBP-1/GPAT signaling pathway， inhibiting oxidative stress responses， and reducing lipid deposition.

Objective:To explore the clinical application value of a combined model based on the radiomics features of magnetic resonance imaging(MRI)and MRI signs in predicting recurrence after radical resection for hepatocellular carcinoma(HCC).Methods:A retrospective analysis was conducted on the imaging data of 100 patients with radical resection for HCC who admitted to Zibo 148 Hospital from May 2016 to May 2020.All patients underwent abdominal enhanced MRI examination before surgery,and they were followed up for at least 2 years after the surgery.They were randomly divided into training group(70 cases)and verification group(30 cases)as a ratio of 7:3.According to the postoperative follow-up results,the training group existed 12 cases of recurrence and 58 cases without recurrence,and the verification group existed 5 cases of recurrence and 25 cases without recurrence.The 3D-slicer software was used to extract radiomics features of preoperative MRI images of each HCC patient.The intra-group correlation coefficient(ICC)of the extracted imaging features of the observers was calculated.The maximum related minimum redundancy(mRMR)algorithm and LASSO regression were selected to analyze the established radiomics labels after dimensionality reduction and screening.Univariate and multivariate logistic regression analysis were used to screen the independent risk factors of predicting recurrence in MRI signs,and they were used respectively to construct radiomics models with the radiomics labels of plain scan,arterial phase,portal phase and hepatobiliary phase.The receiver operating characteristic(ROC)curve was used to assess the diagnostic efficacy of each radiomics model in predicting recurrence.Results:The ICC range of two physicians in selecting radiomics features from the MRI images of all patients were between 0.903 and 0.957,which consistency was favorable(ICC≥0.9).Compared with other predictive models,the highest area under curve(AUC)values of ROC curve of the radiomics model of plain scan of training group[0.951(95%CI:0.901-1.000)]and verification group[0.968(95%CI:0.917-1.000)]were respectively 0.951 and 0.968 in predicting recurrence after radical resection for liver cancer.Conclusion:The combined model that is constructed on the basis of MRI radiomics features has favorable predictive value for the recurrence of patients after radical resection for HCC.Among of them,the radiomics model of plain scan has a certain guiding role in the clinical implementation of personalized treatment plans under the absence of enhancement,and in underdeveloped areas.

Objective To study the expression of N6-methyladenosine(m6A)methyltransferase-like protein 16(METTL16),Ankyrin repeat and SOCS box containing protein 4(ASB13)in elderly breast cancer tissues and their relationship with clinicopathological features and prognosis.Methods 124 elderly patients with breast cancer diagnosed and treated in the Zibo 148 Hospital from January 2019 to January 2021 were selected.Immunohistochemistry(IHC)was used to detect the expression of METTL16 and ASB13 proteins in tissues.Real time fluorescence quantitative PCR(RT-qPCR)was used to detect the expression of METTL16 mRNA and ASB13 mRNA in tissues.Pearson correlation was used for correlation analysis.Survival analysis used Kaplan-Meier curves and Log Rank tests to compare the prognostic differences among patients with different METTL16 and ASB13 expression levels.COX regression analysis was used to analyze the prognostic factors of elderly patients with breast cancer.Results The positive rate of METTL16 in cancer tissue(70.97%)was higher than that in adjacent tissues(8.06%),while the positive rate of ASB13(22.58%)was lower than that in adjacent tissues(72.58%),the differences were statistically significant(χ2=102.642,62.146,all P<0.001).METTL16 mRNA,Snail mRNA and N-cadherin(N-cd)mRNA were higher in cancer tissues than in adjacent tissues,while ASB13 mRNA was lower in adjacent tissues,the differences were statistically significant(t=40.498～48.624,all P<0.001).METTL16 mRNA was positively correlated with Snail mRNA and N-cd mRNA in cancer tissue(r=0.712,0.669,all P<0.001),while ASB13 mRNA was negatively correlated with Snail mRNA and N-cd mRNA(r=-0.734,-0.759,all P<0.001).Compared with TNM stage Ⅰ-Ⅱ and patients with high to medium differentiation,patients with TNM stage Ⅲ and low differentiation had higher positive rate of METTL16 in cancer tissue and lower positive rate of ASB13,the differences were statistically significant(χ2=5.340～10.370,all P<0.05).The 3-year progression free survival rate(73.86%)of the METTL16 positive group was lower than that of the METTL16 negative group(88.89%),the 3-year progression free survival rate(92.86%)of the ASB13 positive group was higher than that of the ASB13 negative group(73.96%),and the differences were statistically significant(Log Rank χ2=4.483,4.882,all P<0.005).METTL16 positive,TNM stage Ⅲ,poor differentiation were risk factors affecting the prognosis of elderly breast cancer,and ASB13 positive was protective factors(Wald χ2=5.056～9.267,all P<0.001).Conclusion METTL16 expression is up-regulated and ASB13 expression is down-regulated in elderly breast cancer,both of which are related to the expression of invasion and metastasis genes,and are new prognostic markers for elderly breast cancer.

Objective:To evaluate the accuracy and safety profile of a novel cuboid orientation-guided frontal horn ventriculostomy technique in patients with large hemispheric infarction (LHI).Methods:It was conducted a retrospective cohort study of 48 consecutive LHI patients who underwent the innovative ventriculostomy procedure between time period. Primary outcomes included procedural accuracy (success rates, catheter positioning) and safety indicators (complication rates).Results:All the punctured ventricles were small or of normal size. The success rate of puncture was 100%, the success rate of one-time puncture was 87% (42/48), and the average number of puncture was 1.13 times per case. The ratio of well-positioned tube heads was 87.5% (42/48). The actual angle of the inward deviation of the puncture ranged from -2o to 5o, with an average of 0o±0.3o. The depth of puncture was 7.0-8.0 cm ( 7.3±0.3) cm. The incidence of bleeding around the puncture path was 1.3% (2/48 ) and no massive bleeding occurred. At the 6-month follow-up, one case (2.94%) among the 34 survivors had epilepsy.Conclusions:The cuboid orientation-guided frontal horn ventriculostomy technique demonstrates exceptional procedural accuracy and an excellent safety profile in LHI patients, with high first-pass success rates (87.5%) and minimal complications (4.2% minor hemorrhage). These findings support its clinical adoption for this patient population.

Objective To investigate the relationship between the expression of cartilage acidic protein-1(CRTAC-1)and proteasome 26S non-ATPase subunit-14(PSMD-14)in lesion tissues and recurrence after laparoscopic radical gastrectomy(LRG)for gastric cancer.Methods A total of 126 gastric cancer patients who underwent LRG at the hospital between January 2019 and December 2021 were enrolled.Recurrence rates were tracked during a 3-year postoperative follow-up,and patients were divided into recurrence group and non-recurrence group.Immunohistochemistry was used to detect CRTAC-1 and PSMD-14 protein expression in gastric cancer lesion and adjacent tissues.Kaplan-Meier method was constructed to evaluate disease-free sur-vival after LRG for patients with positive or negative expression of CRTAC-1 and PSMD-14.Receiver operat-ing characteristic(ROC)curve was drawn to calculate the area under the curve(AUC)to assess the predic-tive value of CRTAC-1 and PSMD-14 protein expression for recurrence after LRG.Results Compared to adja-cent tissues,the positive expression rates of CRT AC-1 and PSMD-14 in gastric cancer lesion tissues were sig-nificantly higher(52.38％vs.11.11％,57.14％vs.16.67％,P＜0.05).The 3-year recurrence rate after LRG in 126 patients was 34.13％(43/126).The recurrence group had higher positive expression rates of CRTAC-1 and PSMD-14(86.05％vs.34.94％,93.02％vs.38.55％,P＜0.05).The 3-year recurrence-free survival rate was 65.87％(83/126).Disease-free survival rates after LRG were lower in patients with positive expression of CRTAC-1 and PSMD-14(50.00％,51.39％)than those in patients with negative expression(83.33％,85.19％,P＜0.05).Independent risk factors for recurrence after LRG included TNM stage Ⅲ A(HR=4.400,95％CI:2.073-9.339),lymph node metastasis(HR=2.751,95％CI:1.412-5.361),positive CRTAC-1 expression(HR=3.521,95％CI:1.967-6.239),and positive PSMD-14 expression(HR=4.241,95％CI:2.347-7.134,P＜0.05).The AUC for combined CRTAC-1 and PSMD-14 protein expression to pre-dict recurrence after LRG was 0.869(95％CI:0.798-0.923),which was higher than that of CRTAC-1 or PSMD-14 alone(0.756,95％CI:0.671-0.828;0.772,95％CI:0.689-0.842,P＜0.05).Conclusion Elevat-ed expression of CRTAC-1 and PSMD-14 in gastric cancer lesion tissues is closely associated with recurrence after LRG and may serve as auxiliary predictive biomarkers for postoperative recurrence in gastric cancer pa-tients.

Post-stroke cognitive impairment (PSCI) is a common complication of stroke, which seriously affects the quality of life of patients. Therefore, early and accurate prediction of PSCI is crucial for implementing targeted intervention measures. Quantitative electroencephalography (qEEG), as a non-invasive and objective neurophysiological technique, can provide objective basis for early prediction and targeted intervention of PSCI during the critical period of 72 hours to 1 month after stroke onset. This article reviews the current application status of qEEG in predicting PSCI, aiming to provide theoretical basis for early identification of patients with high-risk PSCI.

Objective:To compare the benefits and prognostic risks of unilateral lobectomy (with or without isthmusectomy) or total (or near-total) thyroidectomy for primary foci of unilateral papillary thyroid cancer (PTC) patients with ipsilateral lateral cervical lymph node metastasis (LLNM) , so as to find out the optimal surgery for these patients.Methods:A total of 505 unilateral PTC patients with ipsilateral LLNM who underwent initial surgical treatment at the Thyroid Surgery Department of Zhejiang Cancer Hospital from Feb. 2012 to Jan. 2020 were retrospectively reviewed. The patients were divided into unilateral lobectomy group ( n=314) and total thyroidectomy group ( n=191) according to the extent of resection of primary foci. Then 177 pairs of cases were screened out after eliminating the potential confounding bias between the two groups by using propensity score matching (PSM) , analyzing the differences in clinical outcomes such as recurrence-free survival (RFS) , overall survival (OS) , hospitalization costs, and postoperative complications between the two groups. Results:After PSM, the postoperative complication rate was 37.3% ( n=66) in the total thyroidectomy group and 3.4% ( n=6) in the unilateral lobectomy group. The complication was mainly characterized by temporary hypoparathyroidism (HP) . Although the difference in length of hospitalization between the two groups was not statistically significant ( P=0.792) , patients in the unilateral lobectomy group used less surgical time ( P<0.001) , had lower hospitalization and surgical costs ( P<0.0001) , and took a relatively smaller dose of levothyroxine (L-T4) one month after the operation ( P<0.0001) , as compared with the total thyroidectomy group. Univariate analysis showed that the number of LLNM total lymph node metastasis (LNM) rate, LLNM rate, and T stage were significant risk factors for relapse. Multi-factor regression analysis indicated that T-staging was a risk factor for recurrence. After a median follow-up of 60 (3-138) months, 19 patients (10.7%) in the unilateral lobectomy group and 11 patients (6.2%) in the total thyroidectomy group recurred, with no statistical difference between the two groups ( P=0.133) . The OS curve displayed no significant difference between the unilateral lobectomy and total thyroidectomy groups ( P=0.740) . Conclusion:For unilateral PTC patients with ipsilateral LLNM without other high-risk features, unilateral lobectomy could be a better option.

Objective To evaluate the status of latent tuberculosis infection(LTBI)with Mycobacterium tubercu-losis and the risk of LTBI activation after glucocorticoid therapy in patients with anti-neutrophil cytoplasmic antibody(ANCA)-associated vasculitis(AAV).Methods Clinical data of AAV patients who visited Xiangya Hospital of Central South University from May 2018 to May 2023 were retrospectively analyzed.According to the results of in-terferon-γ release assay(IGRA),they were divided into a LTBI group and a non-LTBI group.The LTBI group was subdivided into an active TB group(ATB group)and a non-ATB group according to the presence of ATB.General conditions and biochemical indicator characteristics of the two groups were compared.The COX regression model was used to analyze the risk factors for LTBI activation in AAV patients.Results A total of 302 AAV patients were included in this study,with an age of 64.0(53.0,71.0)years old,169 male cases(55.96％),and an IGRA positive rate of 24.17％(n=73).The proportion of patients with renal insufficiency in the LTBI group was higher than that in the non-LTBI group(79.45％vs 60.70％),with statistically significant difference(P＜0.05).In the LTBI group,the age of patients was 62.0(53.5,72.0)years old,44 cases were male(60.27％),out of which 11 cases(15.07％)had ATB.In the non-LTBI group,4 male cases(1.75％)had ATB.In the LTBI group,there were statistically significant differences between the ATB group and the non-ATB group in terms of daily average glucocorticoid levels,age,renal dysfunction,neutrophils,and blood creatinine(all P＜0.05).COX univariate re-gression analysis showed that statistically significant differences existed among the groups in terms of daily average glucocorticoid levels,daily average glucocorticoid levels＞11.75 mg/day,age,age＞65 years old,and blood crea-tinine levels ≥150 μmol/L(all P＜0.05).COX multivariate regression analysis showed that daily average glucocor-ticoid levels＞11.75 mg/day(OR=0.14,95％CI:1.30-79.01)and age＞65 years(OR=0.08,95％CI:0.01-0.85)were independent influencing factors for LTBI activation.Conclusion AAV patients have a high rate of LT-BI,and daily average glucocorticoid levels＞11.75 mg/day is an independent risk factor for LTBI activation in AAV patients.Age＞65 years may benefit from receiving lower doses of immunosuppressive therapy,but it is necessary to expand sample size for further study.
