Hepatocellular carcinoma(HCC),commonly known as primary liver cancer,is a major cause of malignant tumors and cancer-related deaths in China,accounting for approximately 85％of all cancer cases in the country.Several guidelines have been used to diagnose and treat liver cancer.However,these guidelines provide a broad definition for classifying advanced liver cancer,with an emphasis on a singular approach,without considering treatment options for individual patients.Therefore,it is necessary to establish a comprehensive and practical expert consensus,specifically for China,to enhance the diagnosis and treatment of HCC using the Delphi method.The classification criteria were refined for Chinese patients with HCC,and the corresponding optimal treatment regimen recommendations were developed.These recommendations took into account various factors,including tumor characteristics,vascular tumor thrombus grade,distant metastasis,liver function status,portal hypertension,and the hepatitis B virus replication status of patients with primary HCC,along with treatment prognosis.The findings and rec-ommendations provide detailed,scientific,and reasonable individualized diagnosis and treatment strategies for clinicians.

Objective An autoregressive integrated moving average model(ARIMA)was established to predict the incidence of tuberculosis in Heze in 2022.Methods Based on the monthly registered incidence of tuberculosis patients in Heze city from 2010 to 2020,the optimal ARIMA model was established to predict the incidence in 2021 and compare with the actual value,so as to evaluate the prediction effect and predict the incidence trend in 2022.Results The incidence of tuberculosis in Heze city showed a decreasing trend year by year,with certain seasonal changes.The optimal model was ARIMA(0,1,1)(1,1,1)12,the fitting results showed that the overall prediction error rate was 2.59%and the mean absolute percentage error was 17.76%in 2021.The number of cases predicted in 2022 was 1644,which continued to show a downward trend and the epidemic situation was stable.Conclusion ARIMA(0,1,1)(1,1,1)12 model can better predict the short-term incidence trend of tuberculosis in Heze city,but it should be modified according to the changes of monitoring data to improve the prediction accuracy.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

OBJECTIVE: To compare the mRNA level of cell proliferation-related genes Twist1, SIRT1, FGF2 and TGF-β3 in placenta mesenchymal stem cells (PA-MSCs), umbilical cord mensenchymals (UC-MSCs) and dental pulp mesenchymal stem cells (DP-MSCs). METHODS: The morphology of various passages of PA-MSCs, UC-MSCs and DP-MSCs were observed by microscopy. Proliferation and promoting ability of the three cell lines were detected with the MTT method. Real-time PCR (RT-PCR) was used to determine the mRNA levels of Twist1, SIRT1, FGF2, TGF-β3. RESULTS: The morphology of UC-MSCs and DP-MSCs was different from that of PA-MSCs. Proliferation ability and promoting ability of the PA-MSCs was superior to that of UC-MSCs and DP-MSCs. In PA-MSCs, expression level of Twist1 and TGF-β3 was the highest and FGF2 was the lowest. SIRT1 was highly expressed in UC-MSCs. With the cell subcultured, different expression levels of Twist1, SIRT1, FGF2, TGF-β3 was observed in PA-MSCs, UC-MSCs and DP-MSCs. CONCLUSION Up-regulated expression of the Twist1, SIRT1 and TGF-β3 genes can promote proliferation of PA-MSCs, UC-MSCs and DP-MSCs, whilst TGF-β3 may inhibit these. The regulatory effect of Twist1, SIRT1, FGF2 and TGF-β3 genes on PA-MSCs, UC-MSCs and DP-MSCs are different.

Objective To explore the synergism efficacy and mechanism of Warm Purgative and Strengthening Spleen (WPSS) therapy combined with antibiotics in the treatment of sepsis. Methods Thirty-two SPF Spargue-Dawley (SD) rats were used to replicate the rat sepsis model by cecum ligation perforation (CLP) method and equally divided into model control (MC) group, ceftriaxone group, Chinese herbal medicine (CHM) group and ceftriaxone +CHM group. Eight SD rats underwent sham surgery were used as a sham operation (Sham) group. Rats in Sham and MC groups were administered with 0.9% normal saline (NS) by intraperitoneal injection and gavage. Rats in CHM group were administered with modified Dahuang Fuzi Decoction (DFD, 8 mg/kg) by gavage + 0.9% NS by intraperitoneal injection, Bid. Rats in ceftriaxone group were administered with 0.9% NS by gavage and ceftriaxone (120 mg/kg) by intraperitoneal injection, Bid. Rats in ceftriaxone + CHM group were administered with modified DFD (8 mg/kg) by gavage and ceftriaxone (120 mg/kg) intraperitoneal injection, Bid. The drugs were given for 2 days. The mortality of rats in each group was observed after treatment. The intestinal flora changes and intestinal permeability [intestinal mucosa injury index (IMII), intestinal mucosa secretory immunoglobulin (sIgA), serum D-lactic acid, diamine oxidase (DAO) and sIgA] were detected. Meanwhile, the levels of serum inflammation indexes [lipopolysaccharide (LPS), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)] were detected. Results ① Mortality: ceftriaxone+CHM group (25.0%) < CHM group (37.5%) and ceftriaxone group (37.5%) < MC group (50.0%), the differences between groups were statistically significant (all P < 0.05). ② 16S rDNA sequencing analysis: the ratio of Bacteroidetesin in MC group was lower than that in the Sham group [(24.36±7.15)% vs. (45.20±6.05)%], and the ratio of Proteobacteria in MC group was higher than that in Sham group [(10.03±7.55)% vs. (0.41±0.21)%]. The diversity of intestinal flora in ceftriaxone group was significantly lower than that in Sham and CHM groups (404.60±17.09 vs. 470.80±16.97, 469.20±14.59), the differences between groups were statistically significant (all P < 0.05). The principal component analysis (PCA) suggested that the composition of CHM group was closer to that of Sham group, which indicated that WPSS therapy could reduce intestinal flora disorders in rats with sepsis. ③The pathological changes of intestinal mucosa: light microscope showed the intestinal mucosa of Sham group was intact; the intestinal mucosa became thinner, and local inflammatory cells had infiltration in MC group. The thickness of intestinal mucosa in CHM, ceftriaxone and CHM+ceftriaxone groups was slightly thicker, and the infiltration of local inflammatory cells was less than that in MC group. The thickness of intestinal mucosa in CHM group and ceftriaxone+CHM group was slightly thicker than that in the ceftriaxone group, and the arrangement was more regular than that in MC group and ceftriaxone group.④Intestinal mucosa permeability and inflammatory state: IMII, D-lactic acid, DAO, LPS, TNF-α and IL-6 of rats in MC group were higher than those of rats in Sham group [IMII: 4.37±0.56 vs. 0.26±0.29, D-lactic acid (mg/L):12.35±0.83 vs. 7.30±1.29, DAO (kU/L): 2.16±0.43 vs. 0.32±0.06, LPS (kU/L): 0.663±0.012 vs. 0.095±0.003, TNF-α (μg/L): 251.03±82.69 vs. 52.15±6.25, IL-6 (μg/L): 160.50±4.77 vs. 54.30±3.36], while sIgA in MC group was lower than that in Sham group (mg/L: 11.57±0.17 vs. 26.76±1.99). IMII, D-lactic acid, DAO, LPS, TNF-α and IL-6 of rats in CHM, ceftriaxone and CHM+ ceftriaxone groups were significantly lower than those of rats in MC group, while sIgA in CHM, ceftriaxone and CHM+ceftriaxone groups were significantly higher than that of rats in MC group. The change of CHM+ceftriaxone group was more significant than those of CHM group and ceftriaxone group [IMII:1.78±0.23 vs. 1.96±0.62, 3.39±0.43, D-lactic acid (mg/L): 8.56±0.37 vs. 9.62±0.57,11.42±0.39, DAO (kU/L):1.14±0.12 vs. 1.72±0.24, 2.01±0.32, sIgA (mg/L): 25.34±1.49 vs. 23.99±7.85, 17.46±1.20, LPS (kU/L):0.302±0.007 vs. 0.387±0.004, 0.715±0.013, TNF-α (μg/L): 57.10±3.98 vs. 101.49±21.49, 141.91±20.20, IL-6 (μg/L): 93.71±2.39 vs. 87.12±7.31, 104.27±1.84]. Conclusion WPSS therapy may improve the efficacy of antibiotics in the treatment of sepsis by regulating the intestinal flora and reducing the intestinal mucosa permeability and inflammation level.

OBJECTIVE： To observe neuroprotective effects of low-molecular-weight chondroitin sulfate （CS） on dopaminergic neurons in Parkinson’s disease （PD） mice model induced by 1-methyl-4-phenyl-1，2，3，6-tetrahydropyridine （MPTP）. METHODS： C57BL/6 mice were randomly divided into control group， MPTP injury group， low-molecular-weight CS low-dose and high-dose groups （100， 400 mg/kg）. Control group and MPTP injury group were given constant volume of normal saline intragstrically， administration groups were given relevant medicine intragastrically， once a day， for consecutive 17 d. Since 11th day after medication， except for control group， other groups were given MPTP solution （20 mg/kg） intraperitoneally to induce PD model， once a day， consecutive 5 d. After last medication， behavioral changes of mice （10 mice in each group） were evaluated by rotary rod fatigue tester. The damage of dopamine neurons （the percentage of TH positive cell and the percentage of fluorescence intensity） in substantia nigra of mice （3 mice in each group） was detected by immunohistochemistry and immunofluorescence. The content of dopamine in striatum was determined by HPLC （6 mice in each group）. The changes of oxidant stress indexes （SOD， GSH-Px， MDA） in substantia nigra of mice were determined by chemical colorimetry （6 mice in each group）. RESULTS： Compared with control group， retention time of mice on rotating rods was shortened significantly in MPTP injury group； TH positive cells of substantia nigra were decreased significantly， fluorescence intensity was obviously weakened； the percentage of positive cells and fluorescence intensity， the content of dopamine in striatum， the activities of SOD and GSH-Px in substantia nigra were decreased significantly， while the content of MDA was increased significantly （P＜0.01）. Compared with MPTP injury group， retention time of mice on the rotating rods was prolonged significantly in low-molecular-weight CS groups， the number of TH positive cells was increased significantly in substantia nigra and fluorescence intensity was increased significantly； the percentage of positive cells， the percentage of fluorescence intensity and the content of dopamine in striatum were increased significantly， while above indexes of high-dose group were significantly longer or higher than those of low-dose group （P＜0.05 or P＜0.01）. The activities of SOD and GSH-Px in substantia nigra were increased significantly in low-molecular-weight CS groups， while the content of MDA in substantia nigra was decreased significantly in low-molecular-weight CS high-dose group （P＜0.05 or P＜0.01）. CONCLUSIONS： Prophylactic administration of low-molecular-weight CS can relieve the damage of dopaminergic neurons in substantia nigra of PD model mice induced by MPTP in a dose-dependent manner， and increase the secretion of dopamine in striatum. The effect may be related to the inhibition of lipid peroxidation and the enhancement of antioxidant capacity of tissues.

Psoriasis (Ps) is an inflammatory skin disease caused by genetic and environmental factors. Previous studies on DNA methylation (DNAm) found genetic markers that are closely associated with Ps, and evidence has shown that DNAm mediates genetic risk in Ps. In this study, Consensus Clustering was used to analyze DNAm data, and 114 Ps patients were divided into three subclassifications. Investigation of the clinical characteristics and copy number variations (CNVs) of DEFB4, IL22, and LCE3C in the three subclassifications revealed no significant differences in gender ratio and in Ps area and severity index (PASI) score. The proportion of late-onset ( ≥ 40 years) Ps patients was significantly higher in type I than in types II and III (P = 0.035). Type III contained the smallest proportion of smokers and the largest proportion of non-smoking Ps patients (P = 0.086). The CNVs of DEFB4 and LCE3C showed no significant differences but the CNV of IL22 significantly differed among the three subclassifications (P = 0.044). This study is the first to profile Ps subclassifications based on DNAm data in the Chinese Han population. These results are useful in the treatment and management of Ps from the molecular and genetic perspectives.
