stair-climbing test in predicting postoperative cardiopulmonary complications in elderly patients with biliary

Pei-Tu REN BM, Bao-Chun LU MM, Zhi-Liang CHEN MM, Hong FU MM,

《医学前沿（英文）》 2010年 第4卷 第1期   页码 77-81 doi: 10.1007/s11684-010-0005-x

摘要： One hundred and twenty-six patients above 80 years old with biliary diseases undergoing operations in Shaoxing People’s Hospital from Jan. 2002 to Jan. 2007 were analyzed retrospectively. All patients performed a preoperative stair-climbing test, and the risks for cardiopulmonary €complications were evaluated with pair-matching and linear correlations analysis between stair-climbing height (h) and left ventricular ejective factor (EF), forced vital capacity (FVC) and forced expiratory volume in one second (FEV). There was a significant difference in the incidence of cardiopulmonary complications among different stair-climbing heights. Stair-climbing heights were positively related with EF, FVC and FEV. This suggests that the stair-climbing test is an effective and simple method for predicting cardiopulmonary complications in elderly patients with biliary diseases.

Observation on therapeutic efficacy of ursodeoxycholic acid in Chinese patients with primary biliary

null

《医学前沿（英文）》 2013年 第7卷 第2期   页码 255-263 doi: 10.1007/s11684-012-0227-1

摘要：

The efficacy of ursodeoxycholic acid (UDCA) on long-term outcome of primary biliary cirrhosis (PBC) has been less documented in Chinese cohort. We aimed to assess the therapeutic effect of UDCA on Chinese patients with PBC. In the present study, 67 patients with PBC were treated with UDCA (13–15 mg?kg-1?day-1) and followed up for 2 years to evaluate the changes of symptoms, laboratory values and histological features. As the results indicated, fatigue and pruritus were obviously improved by UDCA, particularly in patients with mild or moderate symptoms. The alkaline phosphatase and γ-glutamyl transpetidase levels significantly declined at year 2 comparing to baseline values, with the most profound effects achieved in patients at stage 2. The levels of alanine aminotransferase and aspartate aminotransferase significantly decreased whereas serum bilirubin and immunoglobulin M levels exhibited no significant change. Histological feature was stable in patients at stages 1–2 but still progressed in patients at stages 3–4. The biochemical response of patients at stage 2 was much better than that of patients at stages 3–4. These data suggest that, when treated in earlier stage, patients in long-term administration of UDCA can gain favorable results not only on symptoms and biochemical responses but also on histology. It is also indicated that later histological stage, bad biochemical response and severe symptom may be indicators of poor prognosis for UDCA therapy.

TNF-α in patients with advanced malignant obstructive jaundice treated by percutaneous transhepatic biliary

ZHU Lidong, CHEN Xiaoping

《医学前沿（英文）》 2007年 第1卷 第4期   页码 364-368 doi: 10.1007/s11684-007-0070-y

摘要： The aim of this article was to study the influence of immunity function of advanced malignant obstructive jaundice (MOJ) treated by percutaneous transhepatic biliary external and internal drainage. Ninety-six cases of MOJ were divided into two groups according to the different ways of biliary drainage. Fifty-two external drainage tubes were placed in 41 cases of percutaneous transhepatic biliary external drainage group and 66 metal stents were placed in 55 cases of percutaneous transhepatic biliary internal drainage group. Liver function, serum TNF- and cellular function were examined one day before operation and one week after operation and liver function was re-examined two weeks after operation, in order to observe the change and analyze the asso ciation among them and compare with the control group. All patients conditions were improved after operation. In the percutaneous transhepatic biliary external and internal drainage groups, the total level of bilirubin decreased from (343.54±105.56) μ mol/L and (321.19±110.50) μ mol/L to (290.56±103.46) μ mol/L and (283.72±104.95) μ mol/L after operation respectively, which were significantly lower than pre-operation (<0.05), but there was no significant difference between the two groups (>0.05). Serum alanine aminotransferase (ALT) of all patients one week after operation was significantly lower than that before operation. TNF- in percutaneous transhepatic biliary external and internal groups decreased from (108.58±19.95) pg/mL, (109.98±16.24) pg/mL of pre-operation to (104.32±19.59) pg/mL, (83.92±13.43) pg/mL of post-operation respectively, there was notable improvement (<0.01) in internal drainage group after operation. Patients serum CD4, CD3 and CD4/CD8 were notably increased, but CD8 was notably decreased (<0.05). There was no difference in external drainage group (>0.05). There was a significant difference between the two groups. Serum TNF- and ALT had positive correlation. Percutaneous transhepatic biliary internal or external drainage was an effective and important method to treat MOJ. Patients immune function was weak when they suffered MOJ, but body s cellular immune function can be notably improved after internal biliary drainage.

Reducing biliary complications in adult-to-adult living donor liver transplantation using right lobe

YAN Lunan, WEN Tianfu, WANG Wentao, YANG Jiayin, XU Mingqing, CHEN Zheyu, WU Hong

《医学前沿（英文）》 2008年 第2卷 第2期   页码 130-133 doi: 10.1007/s11684-008-0024-z

摘要： The aim of this paper is to summarize our experience of using right lobe liver grafts to reduce biliary complications in adult-to-adult (A-A) living donor liver transplantation (LDLT). From January 2002 to October 2007, 124 adult patients underwent living donor liver transplantation using right lobe grafts at the West China Hospital, Sichuan University Medical School, China. There was no death in all donors. Biliary reconstruction for 178 hepatic duct orifices from 124 donor grafts was performed which included 106 reconstructions of duct-to-duct anastomoses and 72 cholangiojejunostomy. Nine recipients had biliary complications including six bile leakages (four from the anastomotic site and two from the cut surface of the liver graft) and three biliary strictures. With the improved techniques for biliary reconstruction, we have achieved good results in 124 recipients of A-A LDLT. We ascribe our success to the introduction of microsurgical techniques and the use of fixed operators which help in decreasing the biliary complications of LDLT.

《医学前沿（英文）》 2012年 第6卷 第4期   页码 354-359 doi: 10.1007/s11684-012-0234-2

摘要：

Beh?et’s disease is defined as a multisystemic inflammatory disease. Although the precise pathogenesis and etiology is still a mystery, accumulating evidence shows that genetic variants of immune-related genes have a profound influence on the development of Beh?et’s disease. To explore the genetic factors for Beh?et’s disease, our group investigated the association of Beh?et’s disease with multiple immune response genes and has identified multiple Beh?et’s disease-related immunoregulatory pathways in the Chinese Han population. A large number of gene polymorphisms were studied including STAT4, IL23R, CD40, CCR1/CCR3, STAT3, OPN, IL17, JAK2, MCP-1, CTLA4, PD-1, PD-L1, PD-L2, TGRBR3, CCR6, PTPN22, FCRL3, IRF5, SUMO4 and UBAC2. Significant associations were found between Beh?et’s disease and STAT4, IL23R, CD40, CCR1/CCR3, STAT3, MCP-1, TGFBR3, FCRL3, SUMO4, UBAC2. These genetic predisposition studies support an important role for both lymphocyte differentiation as well as ubiquitination pathways. These findings are helpful in elucidating the pathogenesis of Beh?et’s disease and hopefully will allow the development of novel treatment regimes.

Minimal residual disease in solid tumors: an overview

《医学前沿（英文）》   页码 649-674 doi: 10.1007/s11684-023-1018-6

摘要： Minimal residual disease (MRD) is termed as the small numbers of remnant tumor cells in a subset of patients with tumors. Liquid biopsy is increasingly used for the detection of MRD, illustrating the potential of MRD detection to provide more accurate management for cancer patients. As new techniques and algorithms have enhanced the performance of MRD detection, the approach is becoming more widely and routinely used to predict the prognosis and monitor the relapse of cancer patients. In fact, MRD detection has been shown to achieve better performance than imaging methods. On this basis, rigorous investigation of MRD detection as an integral method for guiding clinical treatment has made important advances. This review summarizes the development of MRD biomarkers, techniques, and strategies for the detection of cancer, and emphasizes the application of MRD detection in solid tumors, particularly for the guidance of clinical treatment.

Heterogeneity of chronic obstructive pulmonary disease: from phenotype to genotype

null

《医学前沿（英文）》 2013年 第7卷 第4期   页码 425-432 doi: 10.1007/s11684-013-0295-x

摘要：

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality throughout the world and is mainly characterized by persistent airflow limitation. Given that multiple systems other than the lung can be impaired in COPD patients, the traditional FEV1/FVC ratio shows many limitations in COPD diagnosis and assessment. Certain heterogeneities are found in terms of clinical manifestations, physiology, imaging findings, and inflammatory reactions in COPD patients; thus, phenotyping can provide effective information for the prognosis and treatment. However, phenotypes are often based on symptoms or pathophysiological impairments in late-stage COPD, and the role of phenotypes in COPD prevention and early diagnosis remains unclear. This shortcoming may be overcome by the potential genotypes defined by the heterogeneities in certain genes. This review briefly describes the heterogeneity of COPD, with focus on recent advances in the correlations between genotypes and phenotypes. The potential roles of these genotypes and phenotypes in the molecular mechanisms and management of COPD are also elucidated.

Acupuncture for the management of dry eye disease

《医学前沿（英文）》 2022年 第16卷 第6期   页码 975-983 doi: 10.1007/s11684-022-0923-4

摘要： The effectiveness of using acupuncture for dry eye disease (DED) is controversial. Thus, this systematic review investigated the effectiveness and feasibility of using acupuncture for DED in accordance with the 2020 PRISMA statement. The outcomes of interests were (1) to evaluate the efficacy of acupuncture in improving the ocular surface disease index (OSDI), Schirmer I test score, and tear breakup time from baseline to the last follow-up; (2) to determine possible complications of using acupuncture; and (3) to investigate the superiority of acupuncture over other commonly used treatments for DED. Data from 394 patients were collected. Results showed that acupuncture significantly prolonged the tear breakup time (P < 0.0001), significantly increased the Schirmer I test score ( P < 0.0001), and significantly reduced the OSDI ( P < 0.0001) from baseline to the last follow-up. Compared with the control group, the acupuncture group had significantly greater Schirmer I test score ( P < 0.0001), significantly longer tear breakup time ( P = 0.0004), and significantly lower OSDI (P = 0.002). These results suggest that acupuncture is effective and feasible in improving symptoms and signs of DED. No severe adverse effects of acupuncture were observed.

Astrocytes in depression and Alzheimer’s disease

《医学前沿（英文）》 2021年 第15卷 第6期   页码 829-841 doi: 10.1007/s11684-021-0875-0

摘要： Astrocytes are an abundant subgroup of cells in the central nervous system (CNS) that play a critical role in controlling neuronal circuits involved in emotion, learning, and memory. In clinical cases, multiple chronic brain diseases may cause psychosocial and cognitive impairment, such as depression and Alzheimer’s disease (AD). For years, complex pathological conditions driven by depression and AD have been widely perceived to contribute to a high risk of disability, resulting in gradual loss of self-care ability, lower life qualities, and vast burden on human society. Interestingly, correlational research on depression and AD has shown that depression might be a prodrome of progressive degenerative neurological disease. As a kind of multifunctional glial cell in the CNS, astrocytes maintain physiological function via supporting neuronal cells, modulating pathologic niche, and regulating energy metabolism. Mounting evidence has shown that astrocytic dysfunction is involved in the progression of depression and AD. We herein review the current findings on the roles and mechanisms of astrocytes in the development of depression and AD, with an implication of potential therapeutic avenue for these diseases by targeting astrocytes.

Long-de Wang

《工程管理前沿（英文）》 2015年 第2卷 第1期   页码 2-12 doi: 10.15302/J-FEM-2015002

摘要： Chronic non-communicable diseases have become a major threat to humanity. International studies have shown that of 57 million deaths worldwide in 2008, 36 million (63%) were caused by chronic non-communicable diseases; of these, 29 million (80%) occurred in low and middle income countries. The WHO predicts that if the current trend continues, the annual number of deaths due to chronic non-communicable diseases will increase to 55 million by 2030. Due to acceleration of industrialization and urbanization, along with population aging and rapid changes of people’s lifestyle, the morbidity and mortality from chronic diseases are rapidly increasing in China. Therefore, dealing with the prevalence of chronic non-communicable diseases has become one of the current major health issues for China to address. On the basis of summarizing the status of major chronic diseases in China, analyzing the key issues and key factors in chronic disease prevention and control, and reviewing and summarizing the experience from the previous projects, this paper proposes the following recommendations as strategies for chronic disease prevention and control and development of relevant system, which China should adopt. All relevant government departments should formulate corresponding policies; establish a coordinated and efficient work system with rational structure and clear division of tasks and responsibilities within the system. Implementation and development of “integrated medicine” in system is necessary. Work norms and requirements will then improve the performance and efficiency in chronic disease prevention and control in China.

Zooming in and out of ferroptosis in human disease

《医学前沿（英文）》 2023年 第17卷 第2期   页码 173-206 doi: 10.1007/s11684-023-0992-z

摘要： Ferroptosis is defined as an iron-dependent regulated form of cell death driven by lipid peroxidation. In the past decade, it has been implicated in the pathogenesis of various diseases that together involve almost every organ of the body, including various cancers, neurodegenerative diseases, cardiovascular diseases, lung diseases, liver diseases, kidney diseases, endocrine metabolic diseases, iron-overload-related diseases, orthopedic diseases and autoimmune diseases. Understanding the underlying molecular mechanisms of ferroptosis and its regulatory pathways could provide additional strategies for the management of these disease conditions. Indeed, there are an expanding number of studies suggesting that ferroptosis serves as a bona-fide target for the prevention and treatment of these diseases in relevant pre-clinical models. In this review, we summarize the progress in the research into ferroptosis and its regulatory mechanisms in human disease, while providing evidence in support of ferroptosis as a target for the treatment of these diseases. We also discuss our perspectives on the future directions in the targeting of ferroptosis in human disease.

《医学前沿（英文）》 2011年 第5卷 第3期   页码 254-270 doi: 10.1007/s11684-011-0153-7

摘要： Multislice computed tomography (CT) has been widely used in clinical practice for the diagnosis of cardiovascular disease due to its reduced invasiveness and high spatial and temporal resolution. As a reliable alternative to conventional angiography, multislice CT angiography has been recognized as the method of choice for detecting and diagnosing head and neck vascular disease, abdominal aortic aneurysm, aortic dissection, and pulmonary embolism. In patients with suspected coronary artery disease, although invasive coronary angiography still remains as the gold standard technique, multislice CT angiography demonstrates high diagnostic accuracy; in selected patients, it is considered as the first-line technique. The imaging diagnosis of cardiovascular disease is based on a combination of two-dimensional (2D) and three-dimensional (3D) visualization tools to enhance the diagnostic value. This is facilitated by reconstructed visualizations which provide additional information about the extent of the disease, an accurate assessment of the spatial relationship between normal structures and pathological changes, and pre-operative planning and post-procedure follow-up. The aim of the present article is to present an overview of the diagnostic performance of various 2D and 3D CT visualizations in cardiovascular disease, including multiplanar reformation, maximum intensity projection, volume rendering, and virtual intravascular endoscopy. The recognition of the potential value of these visualizations will assist clinicians in efficiently using the multislice CT imaging modality for the diagnostic management of patients with cardiovascular disease.

The epidemiology of norovirus gastroenteritis in China: disease burden and distribution of genotypes

Honglu Zhou, Songmei Wang, Lorenz von Seidlein, Xuanyi Wang

《医学前沿（英文）》 2020年 第14卷 第1期   页码 1-7 doi: 10.1007/s11684-019-0733-5

摘要： With the improvements of sanitation and nationwide safe water supply the occurrence of bacterial diarrhea declined remarkably, while viruses became the leading causes of acute gastroenteritis (AGE). Of these viruses, noroviruses (NoVs) are responsible for a considerable burden of gastroenteritis, especially in children<2 years and elderly≥65 years. NoVs circulating in the Chinese population are antigenically highly diverse with the genotype GII.4 being the dominant strain followed by GII.3. Given the widespread contamination in environmental sources, and highly infectious nature of NoVs, vaccination would be the desirable strategy for the control of NoV infections. However, a better understanding of acquired immunity after infection, and a reliable immunological surrogate marker are urgently needed, since two vaccine candidates based on virus-like particles (VLPs) are currently moving into clinical evaluations in China.

Association of cardiac disease with the risk of post-lung transplantation mortality in Chinese recipients

《医学前沿（英文）》 2023年 第17卷 第1期   页码 58-67 doi: 10.1007/s11684-022-0937-y

摘要： The current organ allocation rules prioritize elderly and urgent patients on the lung transplantation (LT) waiting list. A steady increase in the threshold at which age is taken into consideration for LT has been observed. This retrospective cohort study recruited 166 lung transplant recipients aged ≥ 65 years between January 2016 and October 2020 in the largest LT center in China. In the cohort, subgroups of patients aged 65–70 years (111 recipients, group 65–70) and ≥ 70 years (55 recipients, group ≥ 70) were included. Group D restrictive lung disease was the main indication of a lung transplant in recipients over 65 years. A significantly higher percentage of coronary artery stenosis was observed in the group ≥ 70 (30.9% vs. 14.4% in group 65–70, P = 0.014). ECMO bridging to LT was performed in 5.4% (group 65–70) and 7.3% (group ≥ 70) of patients. Kaplan–Meier estimates showed that recipients with cardiac abnormalities had a significantly increased risk of mortality. After adjusting for potential confounders, cardiac abnormality was shown to be independently associated with the increased risk of post-LT mortality (HR 6.37, P = 0.0060). Our result showed that LT can be performed in candidates with an advanced age and can provide life-extending benefits.
