Objective To investigate the correlation between serum leptin level and body mass index(BMI)in in-fants with cyanosis congenital heart disease,and the relationship between leptin and Ob gene receptor(Ob-R)and hypoxia-inducible factor 1α(HIF-1α)in myocardium.Methods A total of 52 children under 6 months of age with congenital heart disease who underwent surgical treatment in the Department of Congenital Heart Surgery,Fuwai Hospital from January 2019 to October 2020 were included in this study.According to the arterial partial pressure of oxygen(PaO2)of 90 mmHg,they were divided into cyanotic group(n=30)and acyanotic group(n=22).Their height and weight were collected to calculate BMI.The serum leptin level was measured by ELISA.The ex-pressions of HIF-1α and Ob-R in myocardial tissue were detected by RT-PCR and Western blot.In animal mod-el,SD rats were divided into normoxia group and hypoxia intervention group,which were subjected to continuous hypoxia(10% O2)for 4 weeks.The hypoxia intervention group received intraperitoneal injection of HIF-1α in-hibitor digoxin(2 mg/kg)daily from the 14 th to 21st day of hypoxia,respectively.The body weight of rats was recorded,and the expressions of HIF-1α and Ob-R were detected by RT-qPCR and Western blot.Results Com-pared with the acyanosis group,the cyanosis group had a significantly lower BMI(P<0.05)and a lower leptin/BMI ratio(leptin/BMI)(P<0.05).Spearman correlation analysis confirmed that serum leptin in the circulatory system was positively correlated with BMI(P<0.05).In the cyanosis group,the expression of Ob-R increased with the upregulation of HIF-1α,showing a positive correlation.In animal model,with the down-regulation of HIF-1α expression in digoxin injection,the Ob-R level was significantly lower than that in the control group(P<0.05),the trend of weight loss was significantly inhibited(P<0.05).The right ventricular hypertrophy in-dex was significantly lower than that in the control group(P<0.05).Conclusions HIF-1α regulates the expres-sion of Ob-R in myocardial tissue,and the mechanism of its association with leptin and Ob-R may help to find new therapeutic target for improving the prognosis of infants with congenital heart disease.
Résumé
Sepsis is a condition characterized by organ dysfunction resulting from the systemic inflammatory response triggered by an infection. Excessive inflammation and immunosuppression are intertwined, and severe cases may even develop into multiple organ failure. Studies have shown that indoleamine 2,3-dioxygenase 1-mediated tryptophan metabolism is involved in the occurrence and development of sepsis, and elevated plasma kynurenine levels and Kyn/Trp ratios are early indicators of sepsis development. In this paper, we provide a comprehensive summary of the role of IDO1 in the acute inflammatory phase of sepsis, late immunosuppression, and organ damage. This includes its regulation of inflammatory state, immune cell function, blood pressure, and other aspects. Additionally, we analyze preclinical studies on targeted IDO1 drugs. An in-depth understanding and study of IDO may help to understand the pathogenesis and clinical significance of sepsis and multiple organ damage from a new perspective and provide new research ideas for exploring its prevention and treatment methods.

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.

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.
Résumé
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.
Résumé
Represented by colorectal cancer, gastrointestinal malignancies have unique clinical characteristics and biological behaviors, ranking high in the incidence and mortality rates in China. In recent years, with technological innovations and continuous optimization of disease management models, the concept of "precision surgery" has been driving the transformation of colorectal cancer surgery from traditional empirical surgical paradigms to modern precision surgical paradigms. Rapid advancements have been made in colorectal surgical treatment, including surgical techniques, instrument platforms, various novel targeted therapies, and immune combination therapies, which have demonstrated significant efficacy in colorectal cancer treatment. Meanwhile, with 30 years of development in laparoscopic colorectal surgery in China, the surgical approach for colorectal cancer has shifted from traditional open-bellied surgery to minimally invasive surgery. The diagnostic and therapeutic models for colorectal cancer patients have gradually transitioned from experience-driven to precision-based and individualized care. Guided by the concept of "precision surgery", this article combines the current status and trends in colorectal cancer surgery to discuss relevant molecular subtyping and precision treatment strategies, aiming to promote precise surgery and comprehensive treatment for colorectal cancer.

@#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.
Résumé
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 summarize the clinical outcomes and experience of surgical treatment for patients with complete atrioventricular septal defect (CAVSD) above the optimal age for surgery. Methods We retrospectively reviewed clinical data of 163 simple type CAVSD patients less than 7 years who underwent operations in Fuwai Hospital from 2002 to 2013. The patients were divided into a normal group (n=84, including 37 males and 16 females with an average age of 7.6±2.7 months) and an over-age group (n=79, including 30 males and 49 females with an average age of 34.6±19.6 months) according to whether the age was more than 1 year. Results The average aortic cross clamp time (88.3±24.4 min vs. 106.1±35.4 min, P<0.001) and cardiopulmonary bypass time (123.6±31.1 min vs. 142.6±47.1 min, P=0.003) were statistically different between the two groups. During the follow-up period (the normal group 53.3±43.9 months, the over-age group 57.2±48.2 months), there was no statistical difference in all-cause mortality (10.7% vs. 8.9%, P=0.691), the incidence of moderate or severe left atrioventricular valve regurgitation (16.7% vs. 21.5%, P=0.430) and reintervention rate (3.6% vs. 0.0%, P=0.266) between the two groups. No left ventricular outflow tract obstruction and complete atrioventricular block occurred in both groups. Conclusion For CAVSD children above the optimal age, rational surgical treatments can also achieve satisfying results.

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.
Résumé
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.
