Research progress in drugs targeting tumor associated macrophage / 药学学报

Tumor brings great threat to human public health. In recent years, incidence rate and mortality of tumor were rapidly increased in the world. Anti-tumor therapies have undergone the development of cytotoxic therapy, targeted therapy, and immunotherapy. Among them, tumor immunotherapy is rapidly developed and becomes an important anti-tumor therapy in recent years, although it also brings some related side effects. Tumor microenvironment (TME) is composed of immune cells, vascular vessels, fibroblasts, the extracellular matrix, etc. TME significantly affects the efficacy of immunotherapy. Macrophages in the TME are named as tumor associated macrophages (TAMs). Recently, increasing studies have shown that TAMs play an important role in the regulation of tumor immunity, especially in tumor immune surveillance and immune escape. Currently, more and more anti-tumor immunotherapy strategies targeting TAMs are at the development stage. Based on the important role of TAMs in the TME and their potential as therapeutic targets in tumor immunotherapy, we first reviewed the subtypes and functions of TAMs, as well as the roles of TAMs in tumors. Furthermore, we summarized the research progress on anti-tumor strategies targeting TAMs and the current status of drug targeting TAMs. The current review will provide new ideas and novel insights for tumor immunotherapy.

Progress on targets and therapeutic drugs for pancreatic cancer / 药学学报

Pancreatic cancer is a highly malignant tumor with a poor prognosis. It is very hard to treat pancreatic cancers for their high heterogeneity, complex tumor microenvironment, and drug resistance. Currently, gemcitabine plus nab-paclitaxel, capecitabine and FOLFIRINOX are standard chemotherapy for resectable or advanced metastatic pancreatic cancer. Considering the limited efficacy and toxic side effects of chemotherapy, targeted and immune drugs have gradually attracted attention and made some progress. In this article, we systematically reviewed the chemotherapeutic drugs, targets and related targeted drugs, and immunotherapy drugs for pancreatic cancer.

Study on the relationship between the age at natural menopause and postmenopausal metabolic syndrome / 中华预防医学杂志

To explore the relationship between the early or delayed age at natural menopause and metabolic syndrome (MS) in women. A total of 4 734 natural menopausal women who completed the baseline survey from November 2017 to January 2020 in the Guangzhou Middle-aged and Elderly Chronic Disease Prospective Cohort Study were selected in this cross-sectional study. Data on general demographic characteristics, disease history and female physiological health indicators were collected. Logistic regression model and restricted cubic spline curve were used to analyze the relationship between the age at natural menopause and MS. The results showed that the mean age of the subjects was (60±6) years old. The median (Q1,Q3) age at natural menopause was 50 (49, 52) years old, and the prevalence of MS was 14.8%(699/4 734). After adjusting for confounders, the age at natural menopause was closely related to MS in an approximate"U"shape. Compared with the group of normal age at natural menopause, the early age at menopause (OR=1.52, 95%CI: 1.12-2.06) and delayed age at menopause (OR=1.77, 95%CI: 1.36-2.30) had a higher risk of MS. In the group with time since menopause ≤6 years and 7-9 years, the risk of MS in the group with delayed age at menopause was 2.40 times (95%CI: 1.54-3.75) and 2.19 times (95%CI: 1.11-4.31) higher than that in the group with normal menopausal age, respectively. In conclusion, the early and delayed age at natural menopause increased the risk of MS. The increased risk of MS in delayed age at natural menopause mainly occurred within 10 years since menopause.

The application progress on diagnostic scales of laryngopharyngeal reflux disease / 临床耳鼻咽喉头颈外科杂志

At present, objective methods for diagnosing laryngopharyngeal reflux disease(LPRD) are not minimally invasive, effective, and economical. Diagnostic scales are widely used worldwide due to the advantages of inexpensive, noninvasive, and easy to operate. The reflux symptom index(RSI) and the reflux finding score(RFS) are preferred to use in clinical diagnosis. However, many controversies have appeared in the application of RSI and RFS in recent years, causing many troubles to clinical diagnosis. Therefore, this review briefly discusses the problems of RSI and RFS in clinical applications to provide reference for diagnosing LPRD accurately.

Mid- and long-term results of different techniques for subaortic stenosis / 中国胸心血管外科临床杂志

@#Objective    To evaluate the mid- and long-term outcomes of different surgical techniques for subaortic stenosis. Methods    The clinical data of 75 patients with subaortic stenosis who underwent surgery in our hospital from January 2008 to January 2018 were retrospectively analyzed, including 48 males and 27 females, with a median age of 72 (48, 132) months and mean weight of 21.35±15.82 kg. There were 40 (53.3%) patients combined with aortic regurgitation; 38 (50.7%) patients were the first time and 37 patients were the second time to receive the operation. According to the surgical techniques, 75 patients were divided into two groups: a group A (40 patients with simple subaortic membrane resection) and a group B (35 patients with subaortic membrane and muscle resection or modified Konno procedure). Results    Two (2.67%) patients died in hospital. There was one late death in the group B. The average preoperative and postoperative pressure gradient of all patients was 69.96±42.02 mm Hg and 7.44±12.45 mm Hg, respectively. All patients were followed up for 51 (12, 120) months. Pressure gradient at follow-up in the group A and the group B was 8.83±14.52 mm Hg and 5.86±9.53 mm Hg, respectively with no statistical difference (P=0.294). Four patients in the group A and 2 patients in the group B needed reintervention. However, there was no statistical difference in the long-term reintervention rate between the two groups (P=0.480). Conclusion    For the different degree of lesions in the left ventricular outflow tract, our management strategy is feasible. Although there is no statistical difference between two the groups in the long-term reintervention rate after simple valvular membrane resection, prolonged follow-up is necessary to examine the long-term outcomes of different surgical techniques.

Research progress on the regulation of mammalian energy metabolism by the circadian clock system and gut microbiota / 生理学报

The mammalian internal circadian clock system has been evolved to adapt to the diurnal changes in the internal and external environment of the organism to regulate diverse physiological functions, such as the sleep-wake cycle and feeding rhythm, thereby coordinating the rhythmic changes of energy demand and nutrition supply in each diurnal cycle. The circadian clock regulates glucose metabolism, lipid metabolism, and hormones secretion in diverse tissues and organs, including the liver, skeletal muscle, pancreas, heart, and vessels. As a special "organ" of the host, the gut microbiota, together with the intestinal microenvironment (tissues, cells, and metabolites) in a co-evolutionary process, constitutes a micro-ecosystem and plays an important role in the process of nutrient digestion and absorption in the intestine of the host. In recent years, accumulating evidence indicates that the compositions, quantities, colonization, and functional activities of the gut microbiota exhibit significant circadian variations, which are closely related to the changes of various physiological functions under the regulation of host circadian clock system. In addition, several studies have shown that the gut microbiota can produce many important metabolites such as the short-chain fatty acids through the degradation of indigestive dietary fibers. A portion of gut microbiota-derived metabolites can regulate the circadian clock system and metabolism of the host. This article mainly discusses the interaction between the host circadian clock system and the gut microbiota, and highlights its influence on energy metabolism of the host, providing a novel clues and thought for the prevention and treatment of metabolic diseases.

@#Objective    To report the short-term outcomes of a standardized, simplified and reproducible strategy of mitral valvuloplasty (MVP), which was focused on leaflet foldoplasty and anatomic anomalies of congenital mitral regurgitation (MR). Methods    Consecutive 74 patients who underwent MVP by our standardized strategy in our institution from 2016 to 2018 were included retrospectively. There were 30 males and 44 females with a median age of 18.5 (6-146) months and weight of 15.4 (7-51) kg. Results    Anatomic anomalies of MR included: (1) subvalvular apparatus: 72 (97.3%) patients with mal-connected chordae tendineae, 31 (41.9%) with absent chordae tendineae and 14 (18.9%) with fused or dysplastic papillary muscle; (2) leaflet: 10 (13.5%) patients with cleft of anterior leaflet, 61 (82.4%) with leaflet prolapse including 56 (91.8%) with anterior leaflet prolapse; (3) annulus: 71 (95.9%) patients with annular dilatation. Leaflet foldoplasty was performed in 61 (82.4%) patients with leaflet prolapse. All patients were successfully discharged and 4 (5.4%) patients were with moderate MR. The follow-up time was 22.0 (9.1-41.8) months. During the follow-up period, 3 patients had moderate MR and 1 patient had reoperation for severe MR. All patients were in normal cardiac function with a mean left ventricular ejection fraction of 66.0%±6.1%. In addition, the mean left ventricular end-diastolic dimension was 31.8±6.0 mm, which was significant smaller than that before the operation (t=6.090, P<0.000 1). Conclusion    The standardized leaflet foldoplasty with resection of mal-connected chordae tendineae and posterior annuloplasty technique is safe and feasible with favorable short-term outcomes in MR patients.

The role of the intestinal microflora dysbiosis in chronic kidney disease / 药学学报

In recent years the interaction between host and gut microbiota has attracted increasing attention. However, intestinal flora dysbiosis may lead to many diseases, and there is increasing evidence that the intestinal microbiota in patients with chronic kidney disease (CKD) is associated with the pathophysiological status of the host. "Gut-kidney axis" provides a better explanation of the two-way communication between intestinal flora and CKD. Impaired kidney function leads to dysbiosis of intestinal flora and an altered intestinal flora can damage the intestinal mucosal barrier and facilitate the entry into the bloodstream of harmful bacteria, which can induce chronic inflammation and thus accelerate renal injury. In addition, the accumulation of nephrotoxic metabolites from an altered intestinal flora can aggravate CKD in the "gut-kidney axis". Among them, p-cresol sulfate, indoxyl sulfate and trimethylamine oxide are the most widely studied metabolites of nephrotoxicity, and their renal toxicity has been widely confirmed in basic research and clinical studies. Current studies show that the intestinal microbiota-metabolite network is closely related to the occurrence and development of chronic kidney disease. Thus, intervention in the intestinal microbiota may provide a new approach to the prevention and treatment of chronic kidney disease.

Advances in understanding the pathogenic factors and pathogenesis of Parkinson's disease / 药学学报

Parkinson's disease (PD) is the second most common neurodegenerative disease of the central nervous system. It is currently believed that PD is related to factors such as age, gender, family inheritance, gene mutation and environment. The pathogenesis of PD is complex and is related to dysfunction and loss of dopaminergic neurons, involving accumulation of α-synuclein, neuroinflammation, oxidative stress, mitochondrial dysfunction and excessive accumulation of neuromelanin. In many ways, various factors act both independently and through cross-promotion, resulting in an ongoing pattern of brain tissue damage and progressing PD pathology. This article reviews the recent research on the pathogenic factors and pathogenesis of PD and explores new ideas and potential targets for PD treatment and drug development.

Hematopoietic Stem Cells Differentiate into the Megakaryocyte Lineage--Review / 中国实验血液学杂志

Abstract　　Hematopoietic stem cells are able to self-renewal and differentiate to all blood lineages. With the development of new technologies, recent studies have proposed the revised versions of hematopoiesis. In the classical model of hematopoietic differentiation, HSCs were located at the apex of hematopoietic hierarchy. During differentiation process, HSCs progressively lose self-renewal potential to be commited to progenitors with restricted differentiation potential. For instance, HSCs first give rise to multipotent progenitor cells, then produce bipotent and unipotent progenitors, and finally differentiate to mature blood cells. For the differentiation of megakaryocytes, common myeloid progenitors derived from HSCs give rise to megakaryocyte-erythrocyte progenitors and then develop to megakaryocytes. However, recent results show that megakaryocytes can be directly generated from HSCs without multipotent or bipotent phases. Alternatively, platelet-biased HSCs produce megakaryocyte progenitors. In this article, recent advances in the hematopoiesis and megakaryocyte differentiation pathway are reviewed.

Analysis of the strategy to intervene the progress of inflammatory bowel disease by targeting intestinal bacterial respiration and energy metabolism / 药学学报

Gut microbiota dysbiosis is closely related to a variety of host diseases. Recently, targeting the metabolic pathways of gut microbiota for the prevention and treatment of host diseases has become a frontier strategy and research hotspot. Inflammatory bowel disease (IBD) is a group of chronic progressive intestinal inflammatory diseases of unknown etiology. The relationship between IBD and gut microbiota disorders and bacterial respiratory/energy metabolism has been confirmed in recent research. This article will introduce the relationship among them, and propose a new treatment strategy to alleviate host gut inflammation by regulating gut microbiota respiration and energy metabolism based on the latest research progress. In the progression of IBD, the gut microbiota homeostasis is disturbed. The main reasons include two aspects: on the one hand, when the intestinal inflammation of the host occurs, with increasing of oxygen concentration in the intestinal cavity, facultative anaerobic bacteria, especially Enterobacteriaceae bacteria would proliferate abnormally; while the growth of absolute anaerobic bacteria such as Firmicutes is inhibited. On the other hand, intestinal inflammation by-products also support the expansion of facultative anaerobic bacteria, which ultimately exacerbates the imbalance of gut microbiota. Dysregulated intestinal flora will further disturb intestinal immune homeostasis and exacerbate intestinal inflammation. The latest research proposed the possibility that IBD can be alleviated by interfering with the respiration of bacteria, inhibiting the abnormal proliferation of bacteria, or increasing the level of "beneficial" metabolites of gut microbiota. The above studies suggest that alleviating host intestinal inflammation can be explored by focusing on the metabolic pathways of gut microbiota and regulating the intestinal bacterial respiration and energy metabolism, which is of great significance for the clinical treatment of IBD and the research of innovative drugs.

Efficacy of surgical balloon valvuloplasty via right ventricular outflow tract for right ventricular decompression in the treatment of pulmonary atresia with intact ventricular septum / 中国胸心血管外科临床杂志

@#To analyze the mid-long-term outcomes of surgical balloon valvuloplasty (SBV) for right ventricular decompression in the treatment of pulmonary atresia with intact ventricular septum (PA/IVS). Methods    Clinical data of consecutive 91 patients who were diagnosed with PA/IVS and underwent SBV in our institution from January 2005 to December 2017 were retrospectively analyzed, including 52 (57.1%) males and 39 (42.9%) females. The median age was 3 months (1 d, 24 months) and the median weight was 4.1 (2.5, 12.0) kg. Results    The SBV was performed in all patients, and 62 of whom received other simultaneous surgeries, including ligation of patent ductus arteriosus (PDA, 33 patients), ligation of PDA with modified Blalock-Taussig shunt (23 patients), ligation of PDA with bidirectional Glenn shunt (6 patients). There was no early postoperative death. The median follow-up time was 8.8 (2.5, 13.4) years, 4 patients were lost. There were 7 (8.0%) deaths and 1 (1.1%) patient with a re-SBV for pulmonary stenosis. The one and a half ventricular repair was performed in 5 (5.7%) patients and Fontan procedure in 2 (2.3%) patients. In addition, the mean Z-value of tricuspid valve annulus was −1.7±1.5, which was significant bigger than that before the operation (t=5.587, P<0.001). Conclusion    SBV via right ventricular outflow tract for right ventricular decompression in the treatment of PA/IVS is safe and reliable. The majority of patients can receive biventricular repair instead of single ventricular palliation by SBV with individually customized shunt.
