Objective:To investigate the clinical value of abdominal adipose volume in predicting early tumor recurrence after resection of hepatocellular carcinoma (HCC).Methods:The retrospective case-control study was conducted. The clinicopathological data of 132 HCC patients with tumor diameter ≤5 cm who were admitted to The First Affiliated Hospital of Army Medical University from December 2017 to October 2019 were collected. There were 110 males and 22 females, aged (51±4)years. All patients underwent resection of HCC. Preoperative computer tomography scanning was performed and the visceral and subcutaneous fats of patients were quantified using the Mimics Research 21.0 software. Based on time to postoperative tumor recurrence patients were divided to two categories: early recurrence and non-early recurrence. Observation indicators: (1) consistency analy-sis; (2) analysis of factors influencing early tumor recurrence after resection of HCC and construction of prediction model. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribu-tion were represented as M( Q1,Q3) or M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Consistency analysis was conducted using the intragroup correlation coefficient (ICC) test. Multivariate analysis was performed using the binary Logistic regression model forward method. Independent risk factors influencing early tumor recurrence after resection of HCC were screened. The area under curve (AUC) of receiver operating characteristic (ROC) curve was applied to select the optimal cut-off value to classify high and low risks of recurrence. The Kaplan-Meier method was used to draw survival curve and calculate survival time. The Log-Rank test was used for survival analysis. Results:(1) Consistency analysis. The consistency ICC of abdominal fat parameters of visceral fat volume (VFV), subcutaneous fat volume, visceral fat area, and subcutaneous fat area measured by 2 radiologists were 0.84, 1.00, 0.86, and 0.94, respectively. (2) Analysis of factors influencing early tumor recurr-ence after resection of HCC and construction of prediction model. All 132 patients were followed up after surgery for 662(range, 292-1 111)days. During the follow-up, there were 52 patients with non-early recurrence and 80 patients with early recurrence. Results of multivariate analysis showed that VFV was an independent factor influencing early tumor recurrence after resection of HCC ( odds ratio=4.07, 95% confidence interval as 2.27-7.27, P<0.05). The AUC of ROC curve based on VFV was 0.78 (95% confidence interval as 0.70-0.85), and the sensitivity and specificity were 72.2 % and 77.4 %, respectively. The optimal cut-off value of VFV was 1.255 dm 3, and all 132 patients were divided into the high-risk early postoperative recurrence group of 69 cases with VFV >1.255 dm 3, and the low-risk early postoperative recurrence group of 63 cases with VFV ≤1.255 dm 3. The disease-free survival time of the high-risk early postoperative recurrence group and the low-risk early post-operative recurrence group were 414(193,702)days and 1 047(620,1 219)days, showing a significant difference between them ( χ2=31.17, P<0.05). Conclusions:VFV is an independent factor influen-cing early tumor recurrence of HCC after resection. As a quantitative indicator of abdominal fat, it can predict the prognosis of HCC patients.

Objective: To understand the distribution of tobacco retailer within 100 meters outside middle schools in Wuhan City and its impact on smoking behavior of middle school students, so as to provide basis and feasible suggestions for the development of tobacco control policy for adolescents. Methods: From February to May 2023, a multi stage stratified cluster random sampling method was used to select 20 middle schools from 4 districts in Wuhan City. To investigate the distribution of tobacco retailer within 100 metres outside the school and the sale of tobacco to minors. A total of 4 882 students were surveyed using the core questions of the 2021 Chinese Adolescent Tobacco Prevalence Questionnaire. Fisher exact probability test, Chi square test and Chi square trend test were used for statistical analysis. Results: Nearly 70.00% of middle schools had tobacco retailer within 100 metres, with an average of (1.10±0.97) per middle school. The awareness rate (100.00%) and labeling rate (87.50%) of licensed tobacco retailer were higher than those of non licensed tobacco retailer (33.33%, 16.67%) ( P <0.05). The rates of tried smoking, current smoking and buying cigarettes within 30 days were 7.13%, 1.99% and 2.54%, respectively. The rates of students who tried smoking ( 8.58 %), current smoking (2.29%) and buying cigarettes within 30 days (2.85%) in schools with tobacco retailer within 100 metres were higher than those in schools without tobacco retailer (3.79%, 1.28%, 1.83%)( χ 2=35.80, 5.37, 4.37 , P <0.05). And as the grade increased, the rates of tried smoking, current smoking and buying cigarettes among middle school students all showed an upward trend ( χ 2 trend =66.20, 36.10, 16.17, P <0.05). Conclusions Middle school students in Wuhan City have high tobacco availability. The findings suggest that school ban should be extended from 50 meters to 100 meters, and the regulatory authorities must strictly prohibit selling tobacco products to minors at tobacco retailer.

ObjectiveTo explore the therapeutic effect and mechanism of the Danhe granules on hypercholesterolemia rats by observing the changes in the efficacy indicators and the levels of proteins related to the cholesterol metabolism pathway in the rats under the intervention of Danhe granules. MethodSD rats were randomly assigned to either the blank group or the model group based on their body weight. The blank group had normal chow diets， while the model group was fed high-fat diets for seven weeks. One week after the establishment of the model， the content of the serum total cholesterol （TC） in the model rats was detected. According to the TC value， the model group was further randomly divided into a control group， pravastatin sodium tablet group（4.02 mg·kg^-1）， Xuezhikang capsule group（0.12 g·kg^-1）， high-dose， middle-dose， and low-dose groups of Danhe granules（4.536， 2.268， 1.134 g·kg^-1）. After grouping the model groups， each treatment group received continuous oral gavage for six weeks， with weekly measurements of body weight and food intake （the difference between feed intake and feed surplus）. Six weeks later， the levels of serum TC， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） were measured. The liver pathology and lipid droplet distribution were evaluated by hematoxylin-eosin （HE） staining and oil red O staining， with scoring and calculation conducted. Rat liver tissue was collected， and western blot and immunohistochemistry （IHC） were used to detect the expression levels of cholesterol metabolism-related proteins namely phosphorylated adenosine 5'-monophosphate （AMP）-activated protein kinase （p-AMPK）， AMPK， 3-hydroxy-3-methyl glutaryl coenzyme A reductase （HMGCR）， low-density lipoprotein receptor （LDLR）， cholesterol 7α-hydroxylase （CYP7A1）， Acyl-coenzyme A： cholesterol acyltransferase 2 （ACAT2）， and apolipoprotein B （ApoB） in hypercholesterolemia rats. ResultCompared with the blank group， the model group showed a significantly higher level of serum TC （P<0.01）. The TG level had no significant change， and the HDL-C level was significantly decreased （P<0.05）. The liver index， steatosis score， total score of pathological state， and the positive area ratio of oil red O staining were significantly increased （P<0.01）， and the protein expression levels of p-AMPK， p-AMPK/AMPK， LDLR， and CYP7A1 were significantly decreased （P<0.05， P<0.01）， while the protein expression levels of AMPK， HMGCR， and ACAT2 were significantly increased （P<0.05， P<0.01）. Compared with the model group， the TC level in each dose group of Danhe granules was significantly decreased （P<0.05）， and the positive area ratio of oil red O staining in the pravastatin sodium tablet group and medium-dose group of Danhe granules was significantly decreased （P<0.05）. In each administration group， the protein expression levels of p-AMPK and p-AMPK/AMPK were significantly increased （P<0.05， P<0.01）， and the levels of HMGCR and ACAT2 were significantly decreased （P<0.01）. The ApoB level showed a downward trend. The CYP7A1 level in the pravastatin sodium tablet group and each dose group of Danhe granules was significantly increased （P<0.05， P<0.01）， and the LDLR level in the pravastatin sodium tablet group， Xuezhikang capsule group， and high-dose and medium-dose groups of Danhe granules was significantly increased （P<0.05， P<0.01）. ConclusionDanhe granules can reduce serum TC levels and improve hepatic steatosis. It may activate AMPK， down-regulate the expression of HMGCR， and inhibit cholesterol synthesis. It can also up-regulate the expression of LDLR and CYP7A1， promote cholesterol uptake and excretion， down-regulate the expression of ACAT2 and ApoB， reduce cholesterol absorption and assembly of LDL and other lipoproteins， and thus play a role in the treatment of hypercholesterolemia.

This study was aimed at comparing performance differences among three metagenomic sequencing platforms,MGISEQ-2000,Illumina NextSeq 2000,and Ion GeneStudio S5 Plus,to optimize the sequencing process for trace samples.The three sequencing platforms were used to perform high-throughput sequencing on DNA standards and simulated samples.Through analysis of the quality of raw data and microbial detection capabilities,systematic differences among platforms were compared.The sequencing results were optimized for trace samples by incorporation of exogenous nucleic acids during the li-brary preparation process.In terms of data output per batch and base quality,MGISEQ-2000 surpassed the other two plat-forms.Illumina NextSeq 2000 had the lowest proportion of duplicate reads,whereas Ion GeneStudio S5 Plus had the highest proportion,and significant differences were observed across platforms(P＜0.001).In sequencing uniformity,MGISEQ-2000 and Illumina NextSeq 2000 were superior to Ion GeneStudio S5 Plus.MGISEQ-2000 provided a substantial advantage in microbial detection capability(P＜0.001),but the advantage diminished with decreasing bacterial fluid concentration.Ion GeneStudio S5 Plus had the shortest duration for single-batch sequencing.Moreo-ver,for trace samples with DNA content ≤0.05 ng,the experi-mental group(with added exogenous nucleic acids)achieved a higher number of reads than the control group(without exogenous nucleic acids),with a 11.09±8.03 fold increase.In conclu-sion,the different sequencing platforms each had advantages and disadvantages,thus allowing researchers to choose the appro-priate platform according to specific needs.Furthermore,the addition of exogenous nucleic acids improved the microorganism detection efficiency,and provided better support for subsequent diagnosis and evaluation of results.

Objective:To explore the clinical correlation and prognostic value of the Albumin-Bilirubin(ALBI)score in children with secondary hemophagocytic syndrome(sHLH).Methods:A retrospective analysis was conducted on the data of children's sHLH cases clearly diagnosed in the Affiliated Hospital of Zunyi Medical University from January 2012 to March 2023.Survival analysis was conducted according to the ALBI classification.Spearman correlation analysis was conducted between the ALBI score and clinical indicators.The Receiver Operating Characteristic(ROC)curve was used to evaluate the ALBI score,select the best cutoff value,and evaluate the accuracy of prognostic prediction value.Kaplan-Meier method was used to draw the survival curve.Log-rank method was used to compare the differences of survival curve between groups.Cox regression was used for prognostic analysis and restricted cubic spline curves used to calculate the relationship between ALBI scores and the risk of death in children with sHLH.Results:A total of 128 children with sHLH were included in this study,with a median age of 38(13.25,84)months.There were 70 males(54.69％)and 58 females(45.31％).The survival analysis results of ALBI grading showed that the survival rate of HLH patients with ALBI grade 3 was significantly lower than those with ALBI grades 1 and 2.Spearman correlation analysis results showed that ALBI score was positively correlated with splenomegaly,respiratory failure,disseminated intravascular coagulation(DIC),pulmonary hemorrhage,gastrointestinal hemorrhage,central nervous system involvement,ALT,AST,TG,LDH,PT,APTT,and SF(the correlation coefficients are:r=0.181,0.362,0.332,0.221,0.351,0.347,0.391,0.563,0.180,0.448,0.483,0.37,0.356),and was negatively correlated with HB,PLT,and FIB(the correlation coefficients are:r=-0.321,-0.316,-0.423),but was not significantly correlated with EBV infection,fungal infection,hepatomegaly,and ANC(P＞0.05).Using the ROC curve,the cutoff value of ALBI was-1.76.Single factor Cox regression analysis results showed that HB＜90 g/L,ALT ≥ 80 U/L,AST≥200 U/L,LDH ≥1 000 U/L,PT ≥20 s,APTT≥40 s,FIB＜1.5 g/L,ALBI ≥-1.76,combined pulmonary hemorrhage,DIC,central nervous system involvement,gastrointestinal bleeding,and not using blood purification may be the prognostic risk factors for children with sHLH(P＜0.05).Multivariate Cox regression results showed that FIB＜1.5 g/L(HR=2.119,95％CI:1.028-4.368),ALBI≥-1.76(HR=2.452,95％CI:1.233-4.875),and central nervous system involvement(HR=4.674,95％CI:2.486-8.789)were independent risk factors affecting prognosis,while blood purification(HR=0.306,95％CI:0.153-0.612)was an independent protective factor for prognosis.The application of restricted cubic splines shows that the risk of death increases with the increase of ALBI score.The area under the ROC curve(AUC)of the ALBI score for predicting the risk of 1-week,2-week,4-week,and overall mortality were 0.825,0.807,0.700,and 0.693,respectively,indicating good predictive performance for early mortality risk.According to subgroup analysis results of clinical manifestations,compared with the ALBI＜-1.76 group,ALBI≥-1.76 was associated with age ≤2 years,EBV infection,HLH-1994/2004 treatment,concomitant respiratory failure,and ANC≤1.0 × 109/L,HB＜90 g/L,PLT＜100 × 109/L,TG≥3.0 mmol/L,LDH ≥ 1 000 U/L,APTT≥40 s,and FIB＜1.5 g/L(P＜0.05).Conclusion:The ALBI score is related to the clinical characteristics and laboratory indicators of sHLH,and can be used as a beneficial indicator for assessing the prognostic risk of sHLH in children.It has good accuracy and clinical application value in predicting the prognosis of sHLH in children.

Objective:To observe the effect of Xuebijing injection on sepsis combined with acute gastrointestinal injury (AGI), and analyze the risk factors of sepsis combined with AGI.Methods:A retrospective cohort study was conducted. Patients with non-gastrointestinal origin admitted to the department of intensive care medicine of the First Hospital of Qinhuangdao from May 1, 2021 to October 30, 2023 were enrolled. The baseline data, source of sepsis infection, vital signs, acute physiology and chronic health evaluationⅡ(APACHEⅡ), sequential organ failure assessment (SOFA), laboratory tests, comorbidities, interventions during treatment, and the 28-day prognosis were collected. The patients were divided into Xuebijing group and non-Xuebijing group according to whether Xuebijing injection was used or not. According to whether AGI was merged or not, patients were divided into merged AGI group and non-merged AGI group. The main observational indexes were the difference in the incidence of AGI between the Xuebijing group and non-Xuebijing group and the difference in the magnitude of the decline in procalcitonin (PCT), C-reactive protein (CRP), and white blood cell count (WBC) at 7 days after admission, and the difference in the 28-day morbidity and mortality. Risk factors for AGI in septic patients were explored by univariate analysis, and statistically significant indicators were screened and included in binary Logistic regression analysis to determine independent risk factors.Results:A total of 129 patients with sepsis of non-gastrointestinal origin were enrolled, including 57 patients in the Xuebijing group and 72 patients in the non-Xuebijing group. Among 129 patients, 80 patients in the merged AGI group and 49 patients in the non-merged AGI group. There were no statistically significant differences between Xuebijing group and non-Xuebijing group in gender, age, body mass index (BMI), underlying disease, source of infection, vital sign, APACHEⅡscore, SOFA score, and clinical intervention, and there were no statistically significant differences in laboratory tests except for aspartate aminotransferase (AST) and blood urea nitrogen (BUN). The incidence of AGI was significantly lower in the Xuebijing group than that in the non-Xuebijing group [50.87% (29/57) vs. 70.83% (51/72), P < 0.05], and the 28-day mortality was slightly lower than that in the non-Xuebijing group [24.56% (14/57) vs. 30.56% (22/72), P > 0.05]. In the Xuebijing group, the decreases in CRP, PCT and WBC at 7 days after admission were greater than those in the non-Xuebijing group, with statistically significant differences in the decreases of CRP and PCT [CRP (mg/L): 47.12±67.34 vs. 7.76±111.03, PCT (μg/L): 14.08 (-1.22, 50.40) vs. 2.94 (-1.27, 14.80), all P < 0.05]. Univariate analysis showed that the use of acid suppressants, the use of analgesic sedation, the non-use of Xuebijing injections, pulmonary infections, and urinary tract infections were the risk factors for the development of AGI in patients with sepsis. Binary Logistic regression analysis further showed that the use of acid suppressants [odds ratio ( OR) = 2.450, 95% confidence interval (95% CI) was 1.021-5.883, P = 0.045], use of analgesic sedatives ( OR = 2.521, 95% CI was 1.074-5.918, P = 0.034), and urinary tract infection ( OR = 4.011, 95% CI was 1.085-14.831, P = 0.037) were independent risk factors for sepsis combined with AGI, in which the use of Xuebijing injection was a protective factor ( OR = 0.315, 95% CI was 0.137-0.726, P = 0.007). Conclusions:Xuebijing injection reduced the incidence of AGI in patients with non-gastrointestinal sepsis. PCT and CRP decreased more markedly than in patients who did not use Xuebijing injection. The use of acid-suppressing agents, analgesic and sedative agents, and urinary tract infections were independent risk factors for sepsis in combination with AGI, while the use of Xuebijing injection is a protective factor.

This study aimed to investigate the effect and molecular mechanism of sinomenine on proliferation, apoptosis, metastasis, and combination with inhibitors in human hepatocellular carcinoma HepG2 cells and SK-HEP-1 cells. The effect of sinomenine on the growth ability of HepG2 and SK-HEP-1 cells were investigated by CCK-8 assay, colony formation assay, and BeyoClick~(TM) EdU-488 staining. The effect of sinomenine on DNA damage was detected by immunofluorescence assay, and the effect of sinomenine on apoptosis of human hepatocellular carcinoma cells was clarified by Hoechst 33258 staining and CellEvent~(TM) Cystein-3/7Green ReadyProbes~(TM) reagent assay. Cell invasion assay and 3D tumor cell spheroid invasion assay were performed to investigate the effect of sinomenine on the invasion ability of human hepatocellular carcinoma cells in vitro. The effect of sinomenine on the regulation of protein expression related to the protein kinase B(Akt)/mammalian target of rapamycin(mTOR)/signal transducer and activator of transcription 3(STAT3) signaling pathway in HepG2 and SK-HEP-1 cells was examined by Western blot. Molecular docking was used to evaluate the strength of affinity of sinomenine to the target cysteinyl aspartate specific proteinase-3(caspase-3) and STAT3, and combined with CCK-8 assay to detect the changes in cell viability after combination with STAT3 inhibitor JSI-124 in combination with CCK-8 assay. The results showed that sinomenine could significantly reduce the cell viability of human hepatocellular carcinoma cells in a concentration-and time-dependent manner, significantly inhibit the clonogenic ability of human hepatocellular carcinoma cells, and weaken the invasive ability of human hepatocellular carcinoma cells in vitro. In addition, sinomenine could up-regulate the cleaved level of poly ADP-ribose polymerase(PARP), a marker of apoptosis, and down-regulate the protein levels of p-Akt, p-mTOR, and p-STAT3 in human hepatocellular carcinoma cells. Molecular docking results showed that sinomenine had good affinity with the targets caspase-3 and STAT3, and the sensitivity of sinomenine to hepatocellular carcinoma cells was diminished after STAT3 was inhibited. Therefore, sinomenine can inhibit the proliferation and invasion of human hepatocellular carcinoma cells and induce apoptosis, and the mechanism may be attributed to the activation of caspase-3 signaling and inhibition of the Akt/mTOR/STAT3 pathway. This study can provide a new reference for the in-depth research and clinical application of sinomenine and is of great significance to further promote the scientific development and utilization of sinomenine.
