ObjectiveTo investigate the impact of portal vein tumor thrombus （PVTT） classification on rebleeding in hepatocellular carcinoma （HCC） patients with different PVTT subtypes and esophagogastric variceal bleeding （EGVB）， and to provide a reference for formulating rational treatment regimens for such patients. MethodsA retrospective study was performed for 130 patients with HCC and PVTT who were treated due to EGVB in Beijing Ditan Hospital， Capital Medical University， from July 2020 to January 2025， and according to whether endoscopic treatment was performed， the patients were divided into endoscopic treatment group with 97 patients and conservative treatment group with 33 patients. Demographic and clinical data were collected from all patients， and the two groups were compared in terms of hemostasis success rate and rebleeding rate. The independent-samples t test was used for comparison of normally distributed continuous data between groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to estimate the cumulative incidence rate of rebleeding in patients with different subtypes of PVTT. Propensity score matching （PSM） was performed for the endoscopic treatment group and the conservative treatment group to balance the baseline data of the two groups. The Cox proportional hazards model was used to perform univariate and multivariate analyses and identify independent risk factors for rebleeding. ResultsThe endoscopic treatment group had a significantly lower cumulative rebleeding rate within 6 months than the conservative treatment group （35.1% vs 57.6%， hazard ratio ［HR］=0.480， 95% confidence interval ［CI］： 0.272—0.851， P=0.019）. The PVTT Ⅲ—Ⅳ group had a significantly higher cumulative rebleeding rate within 6 months than the PVTT Ⅱ group （52.2% vs 37.5%， HR=1.744， 95%CI： 1.008 — 3.018， P=0.022）. After PSM， there was no significant difference in rebleeding rate between the endoscopic treatment group and the conservative treatment group （38.1% vs 14.3%，HR=1.500，95%CI：0.125 — 2.002， P=0.588）， while the PVTT Ⅲ—Ⅳ group had a significantly higher cumulative rebleeding rate than the PVTT Ⅱ group （58.8% vs 12.5%，HR=1.561，95%CI：1.195 — 12.499，P=0.033）. The multivariate Cox regression analysis showed that PVTT subtype （HR=1.412， 95%CI： 0.998 — 1.997， P=0.049）， platelet count （HR=1.006， 95%CI： 1.001 — 1.010， P=0.021）， C-reactive protein （HR=1.011， 95%CI： 1.001 — 1.021， P=0.026）， and ascites （HR=1.803， 95%CI： 1.059 — 3.068， P=0.030） were independent risk factors for rebleeding. ConclusionFor HCC patients with PVTT and EGVB， endoscopic treatment can successfully achieve hemostasis， while it fails to significantly reduce rebleeding rates. PVTT classification can affect the risk of rebleeding， and patients with PVTT types Ⅲ—Ⅳ have a relatively high rebleeding rate.

ObjectiveTo investigate the risk factors for rebleeding after endoscopic therapy for esophageal and gastric varices in liver cirrhosis patients， to construct a clinical predictive model， and to provide a reference for predicting rebleeding in the early stage， reducing the incidence rate of rebleeding， and improving the clinical outcome of patients. MethodsA retrospective analysis was performed for the clinical data of 194 liver cirrhosis patients with gastroesophageal variceal bleeding who received initial endoscopic therapy at Department of Gastroenterology， The Second People’s Hospital of Lanzhou， from January 1， 2021 to May 31， 2025. According to whether rebleeding occurred within 1 year after endoscopic therapy， the patients were divided into rebleeding group and non-rebleeding group. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The patients enrolled were randomly divided into a training set and a validation set at a ratio of 7∶3. In the training set， the Lasso regression analysis was used to obtain optimal predictive variables， and the factors that might affect prognosis were included in the univariate and multivariate Logistic regression analyses to identify independent predictive factors for rebleeding after endoscopic therapy for esophageal and gastric varices in liver cirrhosis patients， which were used to construct a nomogram model. In both the training set and the validation set， the receiver operating characteristic （ROC） curve and the calibration curve were used to assess the discriminatory ability and calibration of the model， and decision curve analysis and the clinical impact curve were used to assess the clinical practicability of the model. ResultsAmong the 194 liver cirrhosis patients with esophageal and gastric varices， 116 （59.79%） experienced rebleeding within 1 year after endoscopic therapy， with 76 patients in the training set and 40 patients in the validation set. In the training set， the Lasso regression analysis and the univariate and multivariate Logistic regression analyses showed that etiology of liver cirrhosis （odds ratio ［OR］=3.540， 95% confidence interval ［CI］： 1.520 — 7.150， P<0.001）， Child-Pugh class （OR=3.560， 95%CI： 1.380 — 9.500， P=0.019）， severity of esophageal and gastric varices （OR=8.190， 95%CI： 3.568 — 17.850， P=0.026）， and main portal vein diameter （OR=2.954， 95%CI： 1.349 — 15.030， P=0.044） were independent predictive factors for rebleeding of esophageal and gastric varices in liver cirrhosis patients. A nomogram model was constructed based on the above independent predictive factors. The ROC curve analysis showed that this model had an area under the ROC curve of 0.845 （95%CI： 0.778 — 0.912） in the training set and 0.801 （95%CI： 0.798 — 0.868） in the validation set. The model had an index of concordance of 0.832 in the training set and 0.820 in the validation set， suggesting that the model had a good discriminatory ability. The Hosmer-Lemeshow test showed P values of 0.320 and 0.550 in the training set and validation set， respectively， the calibration curve indicated that the predicted probabilities of the nomogram model were in good concordance with the actual observed probabilities， suggesting that the model had good calibration. The decision curve analysis and the clinical impact curve showed that the model had good clinical utility. ConclusionThe nomogram model based on etiology of liver cirrhosis， Child-Pugh class， severity of esophageal and gastric varices， and main portal vein diameter has a certain clinical value in predicting the risk of rebleeding from esophageal and gastric varices in liver cirrhosis.

Existing studies revealed that there were still problems such as long waiting times for appointments and consultations (292 articles), uneven distribution of medical resources (198 articles), and poor doctor-patient communication (155 articles). To improve patients′medical experience, the following intervention measures were proposed: accelerating the medical reform process and strengthening government responsibilities (169 articles); enhancing service concepts and innovating service models (363 articles); optimizing the consultation process and simplifying medical procedures (221 articles); improving the consultation environment and optimizing the facilities in the consultation area (181 articles); and integrating technological advantages to cover the entire medical process (346 articles). Conclusions:Research on improving patients' medical experience was increasingly attracting the attention of more and more scholars. Issues such as low service efficiency, unbalanced resource allocation, and poor doctor-patient communication need to be given special attention. In the future, it is recommended to enhance the experience of patients′ medical experience by strengthening policy and institutional guarantees, accelerating the construction of information technology, improving doctor-patient communication skills and humanistic care, and enhancing the capacity of primary medical services.

ObjectiveTo investigate the safety and efficacy of puncture cyanoacrylate selective seal （PCSS） under endoscopic ultrasound in the treatment of gastroesophageal varices （GOV）. MethodsA total of 100 patients with liver cirrhosis who underwent endoscopic therapy for the secondary prevention of GOV bleeding in Beijing Ditan Hospital， Capital Medical University， from March 1 to December 31， 2023 were enrolled and randomly divided into PCSS group and traditional endoscopy group. The patients were followed up for 6 months after surgery， and the two groups were compared in terms of clinical outcome and complications. The primary outcome measure was the rate of alleviation or disappearance of GOV， and the secondary outcome measure was variceal rebleeding and death. The independent-samples t test was used for comparison of normally distributed or approximately normally distributed quantitative data between two groups， and the Wilcoxon non-parametric test was used for comparison of non-normally distributed quantitative data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of qualitative data between two groups. ResultsThere were 50 patients in the PCSS group， among whom 1 patient was lost to follow-up， and there were 50 patients in the traditional endoscopy group， among whom 3 patients were lost to follow-up. There were no significant differences between the two groups in baseline data such as age， sex， Child-Pugh class， varices grade， and GOV typing （all P>0.05）. Compared with the traditional endoscopy group， the PCSS group had significantly better results of the number of endoscopic treatment sessions （t=-15.671， P=0.001）， the total amount of tissue adhesive used （t=-2.830， P=0.006）， and the rate of alleviation or eradication of varices sclerosis （χ²=7.078， P=0.029）. Both groups had low rates of postoperative rebleeding， adverse reactions， and complications， and there were no significant differences between the two groups （all P>0.05）. ConclusionCompared with traditional endoscopy， PCSS can significantly enhance treatment outcome while maintaining safety standards.

Objective:This study aims to explore the relationship between the abundance of Lachnoclostridium genus in the gut microbiome and inflammatory markers with cognitive impairment in patients with first-episode schizophrenia. Methods:A total of 87 medication-naive patients with first-episode schizophrenia (patient group) and 87 matched healthy controls (control group) who visited the Department of Psychiatry, the First Affiliated Hospital of Zhengzhou University between January 2020 and December 2022 were selected for this study. A 24-week follow-up was conducted for the patients, and all patients received treatment with risperidone. Venous blood and fecal samples were collected from the subjects at baseline and week 24 to measure the levels of superoxide dismutase-1, erythrocyte sedimentation rate, and the abundance of Lachnoclostridium. The severity of symptoms in patients with schizophrenia was assessed using the Positive and Negative Syndrome Scale, and the cognitive function of all subjects was evaluated using MATRICS Consensus Cognitive Battery tests. The differences in the abundance of Lachnoclostridium, inflammatory markers, and cognitive scores between groups were analyzed using t-tests, and the correlations between Lachnoclostridium abundance, inflammatory markers, and cognitive scores were analyzed using Pearson correlation analysis. Results:(1) At baseline, compared with the control group, patients with first-episode schizophrenia had lower levels of superoxide dismutase-1( t=6.83, P<0.001) and total cognitive function test scores( t=6.35, P<0.001), and higher abundance of Lachnoclostridium( Z=-4.64, P<0.001). (2) At baseline, the levels of superoxide dismutase-1 in patients with first-episode schizophrenia were positively correlated with social cognition( r=0.30, P=0.005), while erythrocyte sedimentation rate was negatively correlated with information processing speed and social cognition( r=-0.23, -0.31, both P<0.050). The abundance of Lachnoclostridium genus was negatively correlated with speed of processing( r=-0.28, P=0.009), working memory( r=-0.22, P=0.040), and visual memory( r=-0.32, P=0.003). (3) After 24 weeks of risperidone treatment, the levels of superoxide dismutase-1( t=-2.07, P=0.045) and total cognitive function test scores( t=-3.47, P=0.001) increased in patients, while erythrocyte sedimentation rate( t=2.21, P=0.033) decreased. The abundance of Lachnoclostridium genus showed a decreasing trend( Z=1.52, P=0.128) and did not differ significantly from the control group( Z=1.68, P=0.094). (4) Among the 39 patients who completed the 24-week follow-up, the baseline abundance of Lachnoclostridium genus was negatively correlated with attention and vigilance( r=-0.39, P=0.014) and total cognitive function test scores( r=-0.34, P=0.032) at week 24. The baseline erythrocyte sedimentation rate was positively correlated with the differences in speed of processing, working memory, social cognition, and total cognitive function test scores between baseline and week 24( r=0.42, 0.32, 0.41, 0.36, all P<0.050). (5) At baseline, the abundance of Lachnoclostridium genus had predictive value for erythrocyte sedimentation rate( r=0.45, P=0.004), attention and vigilance( r=-0.39, P=0.014), and total cognitive function test scores( r=-0.34, P=0.032) at week 24. Conclusion:In first-episode schizophrenia patients, there is a significant correlation between the abundance of gut Lachnoclostridium and inflammation and cognitive function.

Objective:To explore the role of interaction between stearidonic acid (SDA) and fatty acid desaturase 2 ( FADS2) rs174570 genotyping in the cognitive function of schizophrenia (SCH). Methods:This study is a case-control study, patients with first-episode, drug-na?ve schizophrenia were recruited from the First Affiliated Hospital of Zhengzhou University′s Department of Psychiatry from October 2017 to October 2019. Healthy controls were recruited through advertisements and medical examinations during the same period. Peripheral blood SDA levels of the SCH patient group and the control group were measured and compared using liquid chromatograph-mass spectrometer (LC-MS), and paired sample t-test was conducted to analyze the changes in the patient group before and after treatment with risperidone. Genome-wide association study (GWAS) was used for analyzing the key enzyme of SDA, and analysis of variance was performed to evaluate the relationship between FADS2 single nucleotide polymorphism (SNP) genotyping and the level of SDA. The Positive and Negative Syndrome Scale (PANSS) and the MATRICS Consensus Cognitive Battery (MCCB) were used to assess the severity of psychotic symptoms and cognitive function, the comparison between the two groups was conducted by independent sample t-test, and the changes before and after risperidone treatment were analyzed by paired sample t-test. Linear regression analysis was performed to investigate the relationship between the interaction of SDA and FADS2 rs174570 genotyping, and cognitive impairment in SCH. Results:SDA levels were significantly lower in the SCH group compared to the control group ( t=-10.67, P<0.001). Cognitive score in patients with SCH were lower than that of HCs ( t=-10.30—-3.30, P<0.05 for all). Low levels of SDA in patients with SCH were positively correlated with the score of speed of processing (SOP; r=0.406, P<0.001) at baseline. After six months of treatment with risperidone, serum levels of SDA increased from (3.6±1.9) μmol/L to (4.4±2.3) μmol/L, and paired t-tests showed significant difference ( t=-2.29, P=0.024). The change of SDA levels before and after risperidone treatment was positively correlated with the change of SOP scores ( r=0.327, P=0.002). FADS2 rs174570 genotyping were significantly associated with SDA levels ( F=3.74, P=0.027) and cognitive function scores of SOP ( F=4.28, P=0.017), and attention/vigilance (AV; F=6.74, P=0.002). Pairwise comparisons showed that CC carriers of rs174570 genotype had higher SDA levels than CT and TT carriers ( P=0.024, and 0.048, respectively), and higher total scores of SOP, AV and MCCB than CT carriers ( P=0.006, 0.001, and 0.002, respectively). The interaction of SDA and FADS2 rs174570 genotyping were associated with cognitive function SOP scores in patients with SCH (β=1.82, P=0.029). Conclusion:The interaction of SDA and FADS2 rs174570 genotyping is associated with the cognitive function in patients with SCH.

Objective:To evaluate the reliability and validity of the Face, Legs, Activity, Cry, and Consolability (FLACC) Pain Behavioral Scale, the Children′s Hospital of Eastern Ontario Pain Scale (CHEOPS), and the Objective Pain Scale (OPS) during the general anesthesia recovery period in children with oral therapy, and to explore their screening ability for pain risk, so as to provide information for selecting appropriate pain assessment scales for pediatric patients.Methods:One hundred and four pediatric patients with oral therapy under general anesthesia were recruited at the Stomatological Hospital of Southern Medical University from January to May, 2024. Two researchers observed simultaneously and scored independently using three scales in random order at 15 minutes and 60 minutes after patients arrival at post anesthesia care unit (PACU). Those awake patients also used the Wong-Baker FACES Pain Rating Scale to report their pain. Internal consistency, inter-rater coefficient, construct and criterion validity of three scales were evaluated.Results:The final sample included 97 patients (50 males and 47 females), with an age of (4.88 ± 1.10) years. At 15 minutes and 60 minutes upon arrival at PACU, the Cronbach alpha coefficients for internal consistency of the FLACC, the CHEOPS, and the OPS were 0.993, 0.980, 0.990, and 0.991, 0.974, 0.989, respectively; the inter-rater correlation coefficients were 0.993, 0.985, 0.998, and 0.985, 0.984, 0.984, respectively; exploratory factor analysis extracted one factor from each scale, and cumulative variance contribution rates were 95.116%, 82.145%, 78.417%, and 89.706%, 67.652%, 75.978%, respectively. At 60 minutes upon arrival at PACU, the Spearman correlation coefficients between three scales and the Wong-Baker FACES Pain Rating scale were 0.621, 0.703, 0.588, respectively; Kappa coefficients of three scales were 0.608, 0.683, 0.520, and area under the ROC curve were 0.812, 0.839, 0.812, respectively.Conclusions:The three scales show good reliability and acceptable validity for assessing pain during the general anesthesia recovery period in children with oral therapy. The CHEOPS performs better in pain screening, followed by the FLACC, the OPS.
