Effects of Dianxianqing granules on tau protein in P301S mice by regulating mitophagy / 中国药房

OBJECTIVE To study the effects of Dianxianqing granules on the tau protein in P301S mice by regulating mitophagy. METHODS Totally 36 P301S mice were randomly divided into model group， Dianxianqing granule group （12.48 g/kg）， donepezil hydrochloride group （positive control， 1.3 mg/kg）， with 12 mice in each group； another 10 C57BL6 mice were selected as control group. Administration groups were given relevant drug solutions intragastrically， and control group and model group were given constant volume of water intragastrically. The gavage volume was 20 mL/kg， once a day， for consecutive 5 months. During the experiment， the general condition of mice was observed in each group. After the last medication， the learning and memory ability was determined by Y maze test and Morris water maze test； HE staining was used to observe the morphological changes in brain tissue， and Nissl staining was used to observe the structure of neural cells and the number of Nissl bodies in cerebral tissue. Immunohistochemistry was used to detect the expressions of phospho-tau serine 202/threonine 205 （abbreviated as AT8） in brain tissue. Western blot assay was used to determine the expressions of mitophagy-associated proteins [PTEN-induced putative kinase-1 （PINK1）， Parkin， microtubule-associated protein 1 light chain 3B （LC3B）， p62]， synaptic-associated proteins [postsynaptic density protein-95 （PSD-95）， synaptophysin （SYP）， and growth-associated protein-43 （GAP-43）] and the phosphorylation of tau protein [expressed by the phosphorylation levels of serine 199 （Ser199） and Ser202] in brain tissue. RESULTS The mice in E-mail：lnzyxyqy2003@163.com model group showed symptoms such as white hair， decreased body mass， and lower limb paralysis， with incomplete hippocampal structures in their brain tissue， as well as incomplete cell membrane edges and cell structures； the spontaneous alternating response rate， the times of crossing platform， the number of Nissl bodies， the protein expressions of PINK1， Parkin， LC3B， SYP， GAP-43， and PSD-95 were decreased significantly， compared with control group； swimming latency （fourth and fifth day）， the protein expressions of AT8 and p62，the phosphorylation levels of Ser199 and Ser202 were increased or lengthened significantly， compared with control group （P＜0.05 or P＜0.01）. Compared with model group， the above symptoms and indexes of mice were improved significantly in administration groups （P＜0.05 or P＜0.01）. CONCLUSIONS Dianxianqing granules can effectively improve cognitive impairment in P301S mice，the mechanism of which may be associated with inducing mitochondrial autophagy， reducing the hyperphosphorylation of tau protein， up-regulating the expression of synaptic-associated proteins in brain tissue，and repairing damaged neural cells.

Application of immune checkpoint inhibitors in liver transplantation for patients with hepatocellular carcinoma / 临床肝胆病杂志

Liver transplantation, as one of the radical treatment strategies for hepatocellular carcinoma, has a good clinical effect in patients meeting the Milan criteria; however, the high recurrence rate and metastasis rate after surgery bring great challenges to the long-term survival of such patients. Therefore, how to improve long-term survival rate and reduce postoperative tumor metastasis has become a key problem that needs to be solved urgently. In recent years, immune checkpoint inhibitors (ICIs), with their good safety and objective reactivity, have provided a new opportunity for the treatment of patients with advanced liver cancer and have become potential candidates for improving the therapeutic effect of liver transplantation. At present, early clinical studies have reported the unique advantages of ICIs used alone or in combination in downstaging or bridging therapy before liver transplantation for hepatocellular carcinoma and adjuvant therapy after liver transplantation. Therefore, this article reviews the clinical trials of ICIs in liver transplantation for hepatocellular carcinoma and the advances in the application of ICIs in recent years and discuss its safety and efficacy, in order to provide a certain reference for clinical medication.

Clinical features and long-term prognosis of primary biliary cholangitis in patients with past hepatitis B virus infection / 中华肝脏病杂志

Objective: To investigate the clinical features and long-term prognosis of primary biliary cholangitis (PBC) in patients with past hepatitis B virus (HBV) infection. Methods: 353 cases with PBC who visited the Liver Disease Center of Beijing Friendship Hospital Affiliated to Capital Medical University between January 2000 and January 2018 were retrospectively analyzed and were divided into the past HBV infection group (156 cases) and the no HBV infection group (197 cases). The two groups' baseline clinical features were compared. Ursodeoxycholic acid response rate after one year, GLOBE score, UK-PBC score, and long-term liver transplantation-free survival rate were compared through outpatient and telephone follow-up. Results: PBC with past HBV infection had a significantly reduced female proportion compared to the no HBV infection group (91.9% vs. 79.5%, P = 0.001). However, there were no statistically significant differences in age, biochemical indices, immunological indicators, platelet count, cirrhosis proportion, and others. Ursodeoxycholic acid biochemical response rate was reduced in patients with past HBV infection at the end of one year of treatment, but the difference was not statistically significant (65.8% vs. 78.2%, P = 0.068). In addition, there were no statistically significant differences between the GLOBE score (0.57 vs. 0.59, P = 0.26) and UK-PBC 5-year (2.87% vs. 2.87%, P = 0.38), 10-year (9.29% vs. 8.2%, P = 0.39) and 15-year liver transplantation rates (16.6% vs. 14.73%, P = 0.39). Lastly, the overall 5-year liver transplantation-free survival rate had no statistically significant difference between the two groups of patients (86.4% vs. 87.5%, P = 0.796). Conclusion: Primary biliary cholangitis had no discernible effect in terms of age at onset, biochemical indices, immunological indicators, cirrhosis proportion, ursodeoxycholic acid response rate after one year, GLOBE score, UK-PBC score, or overall liver transplantation-free survival rate in patients with past hepatitis B virus infections.

Ten-year changes in clinical characteristics and antiviral treatment patterns of chronic hepatitis B in China: a CR-HepB-based real-world study / 中华肝脏病杂志

Objective: To understand ten-year changes in clinical characteristics and antiviral treatment patterns of chronic hepatitis B in China. Methods: Patients with chronic HBV infection:demographic, virologic, hematologic, blood biochemistry, and antiviral treatment data were extracted from the China Registry of Hepatitis B (CR-HepB) database between 2012 and 2022 for descriptive statistics and change trend analysis. Multiple group comparisons were conducted using the Kruskal Wallis H test, while counting data was compared between groups using χ (2) test. Results: A total of 180 012 patients with chronic HBV infection were included, with a median age of 40 years old, and a male proportion accounting for 60.2%. The HBeAg positive rate was 43.3%. Over time, the median age of new patients each year increased from 39 to 47 years, while the HBeAg positive rate decreased from 51.3% to 32.8%. The initial diagnosis of patients was mainly CHB (71.4%), followed by hepatitis B cirrhosis (11.8%), inactive HBsAg carrier status (10.6%), and chronic HBV carrier status (6.2%). Among the newly registered patients every year from 2012 to 2022, the proportion of hepatitis B cirrhosis remained stable, but after 2019, the proportion of CHB increased and the proportion of other diagnoses decreased. The proportion of patients with cirrhosis increased with age in different age groups, with 3.5%, 19.3%, and 30.4% in the < 40, 40-69, and≥70 age groups, respectively. The proportion of women in patients with cirrhosis also increased with age, from 16.1% in those < 30 years old to 44.3% in those≥80 years old. From 2012 to 2022, the proportion of patients receiving first-line nucleos(t)ide analog antiviral treatment increased year by year, from 51.0% in 2012-2013 to 99.8% in 2022. Conclusion: The CR-HepB registration data reflect the changes in clinical characteristics and antiviral treatment patterns in patients with chronic HBV infection in China over the past ten years and can thus provide a reference to promote hepatitis B diagnosis and treatment practice, as well as scientific research.

Recompensation of complications in patients with hepatitis B virus-related decompensated cirrhosis treated with entecavir antiviral therapy / 中华肝脏病杂志

Objective: To analyze the occurrence of recompensation conditions in patients with chronic hepatitis B virus-related decompensated cirrhosis after entecavir antiviral therapy. Methods: Patients with hepatitis B virus-related decompensated cirrhosis with ascites as the initial manifestation were prospectively enrolled. Patients who received entecavir treatment for 120 weeks and were followed up every 24 weeks (including clinical endpoint events, hematological and imaging indicators, and others) were calculated for recompensation rates according to the Baveno VII criteria. Measurement data were compared using the Student t-test or Mann-Whitney U test between groups. Categorical data were compared by the χ (2) test or Fisher's exact probability method between groups. Results: 283 of the 320 enrolled cases completed the 120-week follow-up, and 92.2% (261/283) achieved a virological response (HBV DNA 20 IU/ml). Child-Pugh and MELD scores were significantly improved after treatment (8.33 ± 1.90 vs. 5.77 ± 1.37, t = 12.70, P < 0.001; 13.37 ± 4.44 vs. 10.45 ± 4.58, t = 5.963, P < 0.001). During the 120-week follow-up period, 14 cases died, two received liver transplants, 19 developed hepatocellular cancer, 11 developed gastroesophageal variceal bleeding, and four developed hepatic encephalopathy. 60.4% (171/283) (no decompensation events occurred for 12 months) and 56.2% (159/283) (no decompensation events occurred for 12 months and improved liver function) of the patients had achieved clinical recompensation within 120 weeks. Patients with baseline MELD scores > 15 after active antiviral therapy achieved higher recompensation than patients with baseline MELD scores ≤15 [50/74 (67.6%) vs. 109/209 (52.2%), χ (2) = 5.275, P = 0.029]. Conclusion: Antiviral therapy can significantly improve the prognosis of patients with hepatitis B virus-related decompensated cirrhosis. The majority of patients (56.2%) had achieved recompensation. Patients with severe disease did not have a lower probability of recompensation at baseline than other patients.

A case-control study on the association between a healthy lifestyle and obesity among adult twins in Shanghai / 中华流行病学杂志

Objective: To investigate the associations between the numbers of healthy lifestyles and overweight/obesity and abdominal obesity in adult twins in Shanghai. Methods: Based on the Shanghai Twin Registry System Phase Ⅱ survey data in 2017-2018, a case-control study was conducted to analyze the association between healthy lifestyles and obesity and further adjusted for confounders by a co-twin control study. Results: A total of 7 864 adult twins (3 932 pairs) were included. In the co-twin case-control analysis for monozygotic twins, compared with participants with 0 to 2 healthy lifestyles, those with 3 and 4 to 5 healthy lifestyles had a 49% (OR=0.51, 95%CI: 0.28-0.93) and 70% (OR=0.30, 95%CI: 0.13-0.69) lower risk of overweight/obesity, respectively, and a 17% (OR=0.83, 95%CI: 0.44-1.57) and 66% (OR=0.34, 95%CI: 0.14-0.80) lower risk of abdominal obesity, respectively. For each additional healthy lifestyle, the risk of developing overweight/obesity was reduced by 41% (OR=0.59, 95%CI: 0.42-0.85), and the risk of developing abdominal obesity was reduced by 37% (OR=0.63, 95%CI: 0.44-0.90). Conclusion: An increasing number of healthy lifestyles was associated with a marked decreased risk for both overweight/obesity and abdominal obesity.

Liver manifestation of circulatory disorders / 中华肝脏病杂志

The liver is abundant in blood supply and receives 25% of the cardiac output via the hepatic artery and portal vein. Circulatory disorders may cause hepatic injury, resulting in congestive hepatopathy(CH) and ischemic hepatitis(IH). Hepatic congestion arising from increased hepatic venous pressure and decreased cardiac output is the common pathophysiological basis of both CH and IH. In addition, extensive arteriovenous shunts affect portal pressure and cardiac function, leading to alterations of hepatic blood supply. The current review summarizes the pathophysiology, clinical manifestations and therapeutic interventions of the above diseases, in order to provide reference for clinical practice.

Connective tissue diseases and the liver injury / 中华肝脏病杂志

Connective tissue disease (CTD) are closely related to liver abnormality. CTD can affect the liver causing various degrees of liver injury, coexist with other liver diseases, especially autoimmune liver disease (ALD). Medications for CTD can also lead to liver injury or reactivate the hepatitis B virus. CTD patients can also be positive for ALD-related autoantibodies without corresponding manifestation; and vis versa. The diagnosis and differential diagnosis should be made on integrating clinical presentation, laboratory, imaging, and histological studies, not solely relying on autoantibody positivity.

Liver involvement in endocrine diseases / 中华肝脏病杂志

As a secondary endocrine organ, the liver is closely related to the endocrine system. Liver involvement is not uncommon in endocrine diseases, such as hyper/hypothyroidism, diabetes, dysfunction of adrenal and gonadal. It can be manifested in a variety of forms, including hepatocyte injury (elevated transaminase), bile duct injury (cholestasis), hepatocyte steatosis, vascular injury and liver tumor. Direct and indirect liver injury caused by abnormal hormone levels and side effects of drugs for the treatment of endocrine diseases are common pathogenesis. In addition, endocrine diseases can be concomitant with liver diseases, such as autoimmune thyroiditis and autoimmune hepatitis. Systemic diseases can also involve the endocrine system and liver at the same time, such as systemic lupus erythematosus and IgG4 related diseases. For patients with unexplained liver injury, endocrine system diseases should be considered as the differential diagnosis.

Hepatic manifestations of hematological diseases / 中华肝脏病杂志

Liver involvement is often observed in hematological disorders, resulting in liver abnormality, including unconjugated hyperbilirubinemia, monoclonal hyperglobulinemia, portal vein, or hepatic vein thrombosis or portal hypertension, hepatosplenomegaly, or iron accumulation in the liver. Here we summarize the major hematological diseases that often affect the liver: hemolytic anemia, defect in coagulation or anti-coagulation factors, myeloproliferative neoplasm, hemophagocytic lymphohistiocytosis, multiple myeloma, leukemia, and lymphoma. We hope this review will help clinicians diagnose and manage the patients with liver involvement by hematological disorders.

Paying attention to other systemic diseases of hepatic manifestations: a return to common sense in clinical practice / 中华肝脏病杂志

Liver have complex functions with a high workload. Various liver diseases are the result of the interaction of diverse genetic and environmental factors. Moreover, other systemic diseases may also affect liver, producing corresponding manifestations, such as abnormal liver function tests, portal vein or hepatic vein thrombosis, portal hypertension, hepatosplenomegaly and liver space-occupying lesions. Therefore, it is extremely important for hepatologists to have an in-depth understanding of other systemic diseases of hepatic manifestations, especially hematologic, connective tissue, endocrine, and circulatory, in order to improve the level of clinical diagnosis and treatment.

Personalized surgical treatment for portal hypertension based on portal venous hemodynamics / 中华肝胆外科杂志

Objective:To study the clinical results of personalized surgical treatment for portal hypertension based on portal venous hemodynamics.Methods:A retrospective study was performed on patients with portal hypertension who underwent surgical treatment from January 2016 to December 2020 at the People’s Hospital of Ningxia Hui Autonomous Region and Wuhai People’s Hospital. Of 229 patients included into this study, there were 156 males and 73 females, with age of (4±11) years old. Portal vein CT and ultrasound doppler examination were performed preoperatively and portal vein manometry and ultrasound doppler examination were performed intraoperatively to evaluate portal venous hemodynamics. Based on the evaluation results, different surgical treatments were adopted. Postoperative complications and results of the operations were recorded. Long-term outcomes were evaluated by the rate of recurrence of gastroesophageal varices which was classified as disappearance, mild, moderate and severe according to endoscopic findings.Results:All the 229 patients completed the operations successfully. All together 13 operative treatments were used: (1) simple splenectomy ( n=11); (2) devascularization ( n=176), including 86 patients with splenectomy combined with extensive devascularization, 44 patients with splenectomy combined with selective devascularization and with preservation of paraesophageal veins, 39 patients with splenectomy combined with selective devascularization and reconstruction of spontaneous portosystemic shunt (34 patients with selective devascularization and reconstruction of spontaneous gastrorenal shunt and 5 patients with selective devascularization and reconstruction of spontaneous splenorenal shunt), 4 patients with secondary devascularization for variceal recurrence and 3 patients with devascularization and preservation of spleen; (3) shunt procedures were performed in 42 patients including 21 patients with splenectomy combined with coronary renal shunt, 11 patients with splenectomy combined with coronary-caval shunt, 6 patients with distal splenorenal shunt, 2 patients with proximal splenorenal shunt combined with devascularization, 1 patient with right gastroepiploic vein-inferior vena cava shunt and 1 patient with trans-inferior mesenteric vein coronary renal shunt. There were no operative deaths. The Clavien-Dindo grade 3 and above postoperative complication rate was 6.6% (15/229). Two hundred and eight patients were followed up for 6-60 months, with a median follow-up of 38 months. Severe recurrent varices were found in 21 patients (10.1%, 21/208), with 5 patients (2.4%, 5/208) presented with variceal bleeding. The rate of severe varices after selective shunting and selective devascularization by reconstructing the spontaneous portosystemic shunt (4.2%, 3/72) was significantly lower than that of the other devascularization procedures (13.7%, 17/124)(χ 2=4.53, P=0.033). Conclusion:Better clinical results were achieved by selecting the appropriate surgical procedures based on portal venous hemodynamic characteristics of patients. Selective shunting and selective devascularization by reconstructing the spontaneous portosystemic shunts significantly reduced the recurrence rate of severe varies.

Objective To evaluate the safety and efficacy of irreversible electroporation (IRE) combined with neoadjuvant chemotherapy in patients with locally advanced pancreatic cancer. Methods We searched PubMed, Embase, Cochrane Library, Web of Science, China Biomedical Literature Database, CNKI, Wanfang, and VIP databases for articles dated from the establishment of each database to March 2022. Meta-analysis was performed using RevMan5.4 software. Results A total of 3970 patients with locally advanced pancreatic cancer were enrolled in eight studies, including one randomized controlled trial, four retrospective studies, and three prospective studies. The patients were divided into the combined therapy group with 344 patients and the chemotherapy-only group with 3626 patients. Meta-analysis showed that the overall survival of patients in the combined therapy group was significantly higher than that in the chemotherapy-only group (OR=4.52; 95%CI: 2.63-7.77; P < 0.00001). However, no significant difference existed in the disease control rate between the combined therapy group and the chemotherapy-only group (OR=0.58; 95%CI: 0.02-18.74; P=0.76). Moreover, no significant difference existed in the disease progression between the two groups (OR=0.49; 95%CI: 0.23-1.02; P=0.06). The combination of neoadjuvant chemotherapy and IRE had no significant effect on the incidence of adverse reactions of gastrointestinal reaction (OR=0.37; 95%CI: 0.10-1.34; P=0.13) and bone marrow suppression (OR=0.61; 95%CI: 0.26-1.40; P=0.24). Conclusion IRE combined with neoadjuvant chemotherapy can remarkably improve the prognosis of patients with locally advanced pancreatic cancer, and significantly prolong the overall survival.

Saddle pulmonary embolism is not a sign of high-risk deterioration in non-high-risk patients: A propensity score-matched study / 世界急诊医学杂志（英文）

@#BACKGROUND: There is controversy regarding whether saddle main pulmonary artery (MPA) embolism represents a high risk of deterioration in non-high-risk acute pulmonary embolism (PE) patients. This study aims to address this issue by conducting a propensity score matching (PSM) study. METHODS: A total of 727 non-high-risk acute PE patients were retrospectively evaluated. We evaluated the Bova score and risk stratification to examine the risk of deterioration. Deterioration defined as any adverse event within 30 days after admission. Computed tomographic pulmonary angiography was used to identify the embolism type. All patients were matched into four subgroups by PSM according to age, sex, Bova score, and risk stratification: (1) MPA and non-MPA embolism; (2) non-saddle MPA and non-MPA embolism; (3) saddle MPA and non-saddle MPA embolism; (4) saddle MPA and non-MPA embolism. Correlations were analyzed using Cox regression analysis, and deterioration risk was compared between subgroups using Kaplan-Meier analysis. RESULTS: Cox regression analysis revealed that MPA embolism was correlated with deterioration, regardless of whether saddle MPA embolism was included or excluded. Saddle MPA embolism was not correlated with deterioration, regardless of comparison with non-saddle MPA embolism or non-MPA embolism. Patients with MPA and non-saddle MPA embolism presented a high risk for deterioration (log-rank test=5.23 and 4.70, P=0.022 and 0.030, respetively), while patients with saddle MPA embolism were not at a high risk of deterioration (log-rank test=1.20 and 3.17, P=0.729 and 0.077, respetively). CONCLUSIONS: Saddle MPA embolism is not indicative of a high risk of deterioration in non-high-risk acute PE patients.

Effect of proximal splenic vein ligation on prevention of portal vein thrombosis after splenectomy for portal hypertension / 中华普通外科杂志

Objective:To evaluate the preventive effect of proximal splenic vein ligation after splenectomy on the splenic vein originated portal vein thrombosis (PVT) in portal hypertension.Methods:The clinical data of 94 patients of portal hypertension who had received splenectomy were retrospectively analysed. The proximal splenic vein was ligated in 36 cases during pericardial devascularization and coronary renal shunt with splenectomy. The other 58 cases who had received pericardial devascularization without proximal splenic vein ligation served as control. All of the patients in both groups were given heparin infusion postoperatively through the catheter which was placed in the right gastroepiploic vein during operation. CT portal veinography was performed at the 7th-14th postoperative day for detection of PVT.Results:None of the PVT occurred in the splenic vein ligation group. In the control group, PVT occurred in 22 cases(38%) and splenic vein thrombosis occurred in all the 58 cases (100%). PVT incidence between the two groups is significantly different (0 vs. 38%, χ 2=17.828, P<0.05). Conclusions:Ligation of the proximal splenic vein during splenectomy can effectively prevent the postoperative splenic vein originated PVT in portal hypertension.
