Hepatic venous pressure gradient (HVPG) is the "gold standard" for the diagnosis of portal hypertension, which could be applied in the evaluation of liver cirrhosis. Combined use of HVPG with model for end-stage liver disease (MELD) scoring system may more accurately match the donors and recipients undergoing liver transplantation for liver cirrhosis, select the appropriate timing of surgery, and provide guidance for bridging treatment for patients on the waiting list for liver transplantation. Besides, HVPG may also predict clinical prognosis of liver transplant recipients, and provide evidence for early detection and intervention of potential complications. Therefore, the value of HVPG in preoperative evaluation and prognosis prediction of liver transplant recipients was reviewed, aiming to provide guidance for clinical diagnosis and treatment of liver transplant recipients before and after surgery.

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 investigate the diagnostic value of independent and combined subtests of the psychometric hepatic encephalopathy score (PHES) in mild hepatic encephalopathy(MHE) of patients with liver cirrhosis, so as to optimize the PHES.Methods:This was a prospective, multicenter and real-world study which was sponsored by the National Clinical Research Center of Infectious Diseases and the Portal Hypertension Consortium. Twenty-six hospitals from 13 provinces, autonomous regions and municipalities countrywide participated in this study, induding Tianjin Third Central Hospital, the Fourth People′s Hospital of Qinghai Province, the Second Affiliated Hospital of Baotou Medical College, the Third People′s Hospital of Taiyuan, the Fifth Medical Center of PLA General Hospital and so on. From October 2021 to February 2022, outpatients and hospitalized patients with liver cirrhosis and no obvious hepatic encephalopathy were consecutively enrolled. All patients received 5 PHES subjects in the same order: number connection test(NCT)-A, NCT-B, digit symbol test(DST), line tracing test(LTT) and serial dotting test(SDT), and the scores were calculated. The total score of PHES <-4 was taken as the cut-off value for diagnosing MHE. Compare the differences in each subtest between MHE group and non-MHE group. Receiver operating characteristic curve(ROC) and area under the curve(AUC) was performed to assess the diagnostic value of independent and combined subtests in MHE. Mann-Whitney U test and DeLong test were used for statistical analysis. Results:A total of 581 patients with liver cirrhosis were enrolled, 457 were diagnosed as MHE, and the incidence of MHE was 78.7%. The results of NCT-A, NCT-B, SDT, LTT, DST of MHE group were 60.00 s(47.01 s, 88.00 s), 90.45 s(69.32 s, 125.35 s), 74.00 s(57.65 s, 96.60 s), 74.72(60.00, 98.61) and 27.00(20.00, 36.00), respectively. Compared those of non-MHE group(34.00 s(29.15 s, 44.48 s), 50.00 s(40.98 s, 60.77 s), 50.00 s(41.07 s, 63.03 s), 46.23(38.55, 59.42) and 42.00(34.00, 50.75)), the differences were statistically significant( Z=12.37, 12.98, 9.83, 11.56, 10.66; all P<0.001). The AUC(95% confidence interval(95% CI)) of subtests of PHES NCT-B, NCT-A, LTT, DST and SDT alone in MHE diagnosis were 0.880(0.849 to 0.910), 0.862(0.828 to 0.896), 0.838(0.799 to 0.877), 0.812(0.772 to 0.851) and 0.788(0.743 to 0.832), respectively. The combination of 2 PHES subtests significantly increased the diagnostic efficacy. Among them the diagnostic efficacy of the combination of NCT-B and LTT was the best, the AUC(95% CI) was 0.924(0.902 to 0.947), the specificity was 91.9% and the sensitivity was 79.2%, which was better than a single PHES subtest (NCT-A, NCT-B, SDT, LTT and DST) and the combination of NCT-A and DST(AUC was 0.879, 95% CI0.847 to 0.910) which was recommended by guidelines on the management of hepatic encephalopathy in cirrhosis, the differences were statistically significant ( Z=3.78, 3.83, 5.57, 5.51, 5.38, 2.93; all P<0.01). Furthermore, compared between the combination of NCT-B and LTT and the combination of 3 subests of PHES, only the diagnostic efficacy of combination of NCT-B, LTT and SDT (AUC was 0.936, 95% CI 0.916 to 0.956) was better than that of the combination of NCT-B and LTT, the difference was statistically significant( Z=2.32, P=0.020). Conclusion:Based on the diagnostic efficacy and clinical feasibility of PHES subtests and their combinations, the combination of NCT-B and LTT is recommended for the diagnosis of MHE.

Objective:To summarize the clinical manifestation and imaging of superficial siderosis of the central nervous system and explore the potential etiology.Methods:The clinical and imaging data of 7 patients diagnosed as superficial siderosis of the central nervous system in Peking Union Medical College Hospital from May 2013 to November 2019 were retrospectively reviewed. The etiology and follow-up prognosis through phone call were analyzed.Results:There were 7 patients included (3 male and 4 female) with an average age of 53 years (41-58 years). The cardinal manifestations were sensorineural deafness (all 7 cases), cerebellar ataxia (all 7 cases) and pyramidal signs (all 7 cases). Dizziness (6 cases), bladder disturbance (5 cases), headache (3 cases), double vision (2 cases) and congnitive impairment (1 case) could also happen. Magnetic resonance imaging showed symmetrical well-defined curvilinear homogeneous low signal on T 2 or blood-sensitive sequences (T 2* gradient echo or susceptibility-weighted imaging) over the superficial surface of cerebellar, brain stem, and spinal cord or cranio-cervical junction. All the 7 patients showed cerebellar atrophy especially the upper vermis. The potential causes included trauma history in 3 cases, intraspinal fluid-filled collection which indicated dural defect or duropathologies in 3 cases, intraspinal mass in 1 case and vertebral and disc degeneration in all 7 patients. The 5 patients who successsfully got follow-up showed exacerbation of variable degree. Conclusions:Classical superficial siderosis of the central nervous system is a rare disease with cardinal manifestation of progressive ataxia, sensorineural deafness and pyramidal signs. T 2WI of magnetic resonance imaging showing low signal over the superficial surface of cerebellar, brain stem, and spinal cord could indicate the diagnosis, and blood-sensitive sequences such as T 2* gradient echo or susceptibility-weighted imaging were more sensitive. Duropathologies or dural defect may be the most probable causes of the disease and should be examined and treated carefully.

Surgery is an accepted standard in the treatment of adenocarcinoma of esophagogastric junction (AEG), but the efficacy of surgery alone for locally advanced AEG is limited. In-depth studies concerning combined therapy for AEG have been carried out worldwide, including neoadjuvant chemotherapy (nCT), neoadjuvant chemoradiotherapy (nCRT), perioperative chemotherapy (pCT), postoperative chemoradiotherapy, etc. Significantly, the contribution of nCRT and pCT to improving the prognosis of locally advanced AEG patients has been shed light on. Compared with that, multimodality treatment for AEG patients is not well established in China. An attempt was thus made to take an overview of the evidence-based research advance regarding integrated therapy of AEG.

Most hepatocellular carcinoma are diagnosed at an advanced stage and thereby have a high mortality rate. Thus, the key to improving patient prognosis is early diagnosis of hepatocellular carcinoma. In recent years, Asian scholars have summarized a series of hepatocellular carcinoma risk score model for population with chronic hepatitis B, which can help to identify high-risk groups early and improve the early diagnosis rate. This paper briefly analyzes the risk factors and validated risk model for early prediction of hepatitis B virus-related hepatocellular carcinoma, and further reviews the effect of antiviral therapy on the risk of hepatocellular carcinoma.

Objective: To explore the relationship among self-regulatory focus and depression, anxiety symptoms and suicidal risks of medical college students. Methods: A total of 2 251 freshmen were recruited from a medical university by convenienee sampling methood. A cross-sectional questionnaire survey using Regulatory Focus Questionnaire (RFQ), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Beck Hopelessness Scale (BHS), Psychache Scale (PAS), and Suicide Behaviors Questionnaire-Revised (SBQ-R) was conducted. Results: The prevalence rate of freshmen’s depression symptoms was as high as 20.4%, the prevalence rate of anxiety symptoms was 11.2%, and the risk of suicide increased by 5.85 times among students with depression-anxiety comorbid symptoms. Girls reported higher prevention focused scores than boys, as well as higher anxiety symptoms and suicidal risks(t=4.84,2.18,5.57,P<0.05). College students with a prevention focused self-regulation style had significantly higher scores on depression, anxiety symptoms and suicidal risks than those with a promotion focused regulatory style, the effect sizes of the differences were moderate or large (Cohen’s d>0.50). Conclusion Self-regulatory focus plays an important role in emotional health. The pursuit of promotion goals is beneficial to mental health, while the pursuit of prevention goals is more likely to be associated with depression, anxiety symptoms and a higher risk of suicide.

Nonalcoholic fatty liver disease (NAFLD) is a clinicopathological syndrome with similar hepatic histological changes to alcoholic liver disease, but without a history of excessive alcohol intake. Obesity, hyperlipidemia, diabetes, hypertension and other metabolic disorders are closely related to its occurrence and development, and its core mechanism is insulin resistance. In addition, there are also non-metabolic-related factors for the occurrence of non-alcoholic fatty liver disease, such as pancreatoduodenectomy. Pancreatoduodenectomy is the standard procedure for the treatment of tumor around the head of pancreas and ampulla. Postoperative pancreatic malfunction induced by pancreatic exocrine function after pancreatoduodenectomy is associated with the occurrence and development of secondary non-alcoholic fatty liver disease.

Objective To assess the efficacy and safety of 100 mg or 200 mg yimitasvir phosphate combined with sofosbuvir in patients with non-cirrhotic chronic hepatitis C virus ( HCV) genotype 1 infection who were treatment-na?ve or had a virologic failure to prior interferon-based treatment.Methods A multicenter, randomized, open-label, phase 2 clinical trial was conducted.The patients were randomly assigned to yimitasvir phosphate 100 mg+sofosbuvir 400 mg group (Group 100 mg) and yimitasvir phosphate 200 mg+sofosbuvir 400 mg group ( Group 200 mg) in a 1∶1 ratio with the stratified factors of " treatment-naive" or"treatment-experienced" for 12 weeks and followed up for 24 weeks after the end of treatment.During the clinical trial, HCV RNA was tested in all patients.Resistance of virus in patients who didn′t achieved sustained virological response (SVR) was monitored.Safety and tolerability were assessed by monitoring adverse events , physical examination , laboratory examination, electrocardiogram, and vital signs during the study.The primary end point was SVR12 after the end of therapy.Descriptive statistics were used for categorical variables and eight descriptive statistics were used for continuous variables.Descriptive statistics were used and summarized according to HCV genotypes and treatment groups.Safety data were presented using descriptive statistics and summarized according to treatment groups.Results A total of 174 subjects were screened from July 31, 2017 to September 26, 2018.One hundred and twenty-nine patients were successfully enrolled and received treatment , and 127 completed the study.There were 64 patients and 65 patients assigned to Group 100 mg and Group 200 mg, respectively.Among the 129 patients who underwent randomization and were treated , 18.6% were treatment-experienced and: 100%were HCV genotype 1b infection.The total SVR rate was 98.4%(127／129), with 98.4%(63／64, 95%confidence interval [CI]: 91.60%-99.96%) in the Group 100 mg, and 98.50%(64／65, 95%CI: 91.72%-99.96%) in the Group 200 mg.There was no significant difference between the two groups (χ2 ＝0.000 2, P＝0.989 2).The SVR rates in treatment-naive group and treatment-experienced group were 98.10%(95%CI: 93.29%-99.77%) and 100.00%(24／24, 95%CI: 85.75%-100.00%), respectively.Virological failure during treatment ( including breakthrough , rebound and poor efficacy) and relapse after treatment did not occur during the trial.By Sanger sequencing , 11.6%(15／129) patients had baseline NS5A Y93H／Y or Y93H resistance-associated substitutions ( RAS), 1.6%( 2／129) patients had baseline NS5A L31M RAS.No mutation was observed in NS5B S282 at baseline.There was no S282 mutation in HCV NS5B.A total of 100 (77.5%) subjects had adverse events.No adverse events ≥Grade 3 or severe adverse events related to the study treatment.No patient prematurely discontinued study treatment owing to an adverse event.No life-threatening adverse event was reported.Conclusion Twelve weeks of yimitasvir phosphate 100 mg or 200 mg combined with sofosbuvir 400 mg daily is a highly effective and safe regimen for patients without cirrhosis with HCV genotype 1b infection who had not been treated previously or had a virologic failure to prior interferon-based treatment.

Objective To validate the predictive value of hepatitis B virus ( HBV )-related hepatocellular carcinoma ( HCC) risk score model D2AS in chronic HBV infection patients without antiviral therapy.Methods A total of 93 patients with chronic HBV infection were selected between January 2015 and July 2017 in the Third Affiliated Hospital of Hebei Medical University.Clinical data including age , gender, medical history, ultrasonography, hepatitis B surface antigen ( HBsAg), hepatitis B surface antibody ( anti-HBs), hepatitis B e antigen ( HBeAg), hepatitis B e antibody ( anti-HBe), hepatitis B core antibody ( anti-HBc), HBV DNA and alanine aminotransferase levels were collected by information center .REACH-B score and D2AS score were used to predict the risk of HCC.Receiver operating characteristic curve (ROC) was used to evaluate the discrimination , and Hosmer-Lemeshow ( H-L) goodness-of-fit test was used to evaluate the calibration of the model.Results REACH-B score and D2 AS score for the 95 chronic HBV infection patients were 9 (8,12) and 0.95 (0.57,2.08), respectively.The area under the curve ( AUC) for REACH-B score and D2 AS score were 0.916 (95% confidence interval [ CI] 0.834-0.998) and 0.784 (95%CI 0.587-0.981), respectively.The difference was not statistically significant ( P ＝0.195).However, for HBeAg-negative patients with chronic HBV infection , the AUC for D2 AS score and REACH-B score were 0.952 (95%CI 0.876-1.000) and 0.913 (95%CI 0.821-1.000), respectively (P＝0.458).The H-L goodness-of-fit test was P＞0.05.Conclusions The D2 AS score can be used for HCC prediction among patients who do not meet antiviral criteria.The predictive value of the D 2AS score for HCC is comparable to the REACH-B score in HBeAg-negative patients with chronic HBV infection.
