Proteome and genome integration analysis of obesity / 中华医学杂志(英文版)

The prevalence of obesity has increased worldwide in recent decades. Genetic factors are now known to play a substantial role in the predisposition to obesity and may contribute up to 70% of the risk for obesity. Technological advancements during the last decades have allowed the identification of many hundreds of genetic markers associated with obesity. However, the transformation of current genetic variant-obesity associations into biological knowledge has been proven challenging. Genomics and proteomics are complementary fields, as proteomics extends functional analyses. Integrating genomic and proteomic data can help to bridge a gap in knowledge regarding genetic variant-obesity associations and to identify new drug targets for the treatment of obesity. We provide an overview of the published papers on the integrated analysis of proteomic and genomic data in obesity and summarize four mainstream strategies: overlap, colocalization, Mendelian randomization, and proteome-wide association studies. The integrated analyses identified many obesity-associated proteins, such as leptin, follistatin, and adenylate cyclase 3. Despite great progress, integrative studies focusing on obesity are still limited. There is an increased demand for large prospective cohort studies to identify and validate findings, and further apply these findings to the prevention, intervention, and treatment of obesity. In addition, we also discuss several other potential integration methods.

Clinical effects of oral motor intervention combined with non-nutritive sucking on oral feeding in preterm infants with dysphagia

Abstract Objective: To explore the effectiveness of oral motor intervention combined with non-nutritive sucking in treating premature infants with dysphagia. Methods: Sixty preterm infants admitted to the neonatal intensive care unit of the present study's hospital were selected and randomly divided into the control and intervention groups. The control group was given non-nutritive sucking intervention alone, while the intervention group was given oral motor intervention combined with non-nutritive sucking. The oral motor ability, milk sucking amount and sucking rate, feeding efficiency and outcomes, and the occurrence of adverse reactions were measured and compared. Results: Compared to first-day interventions, preterm infant oral feeding readiness assessment scale-Chinese version (PIOFRAS-CV) scores of the two groups significantly increased after 14 days of intervention, and this score was higher in the intervention group compared to the control group. Similarly, after 14 days of intervention, the intervention group's milk sucking rate and amount were significantly higher than the control group. Also, after the intervention, the intervention group's total oral feeding weeks were considerably lower, while the feeding efficiency and body weight were significantly higher than the control group. Moreover, the overall adverse reaction rate in the intervention group was lower than that in the control group. Conclusions: Oral motor intervention combined with non-nutritive sucking can significantly improve the oral motor ability of premature newborns, promote the process of oral feeding, improve the outcome of oral feeding, and reduce the occurrence of adverse effects. The combined intervention seems to have a beneficial effect on oral feeding proficiency in preterm infants.

Moxibustion alleviates decreased ovarian reserve in rats by restoring the PI3K/AKT signaling pathway / 中西医结合学报

OBJECTIVE@#Moxibustion, a common therapy in traditional Chinese medicine, has potential benefits for treating decreased ovarian reserve (DOR). The present study investigates the protective effect of moxibustion in a rat model of DOR and explores the possible mechanisms.@*METHODS@#Sixty-four female Sprague-Dawley rats were randomly divided into four groups: control, DOR, moxibustion (MOX), and hormone replacement therapy (HRT). The DOR rat model was established by intragastric administration of 50 mg/kg Tripterygium glycoside suspension (TGS), once daily for 14 days. MOX and HRT treatments were given from the day TGS administration was initiated. The ovarian reserve function was evaluated by monitoring the estrus cycle, morphological changes in ovaries, levels of serum estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and anti-Mullerian hormone (AMH), pregnancy rate and embryo numbers. Terminal-deoxynucleotidyl transferase-mediated nick-end-labeling staining was used to identify ovarian granulosa cell apoptosis, while the protein and mRNA expressions of Bax, B-cell lymphoma-2 (Bcl-2), phosphatidylinositol 3-kinase (PI3K) and protein kinase B (AKT) in ovarian tissues were examined by immunohistochemistry, Western blot and quantitative reverse transcription-polymerase chain reaction.@*RESULTS@#Compared with the DOR group, MOX improved the disordered estrous cycle, promoted follicular growth, reduced the number of atresia follicles, increased the concentrations of serum E2 and AMH, and decreased serum FSH and LH concentrations. More importantly, the pregnancy rate and embryo numbers in DOR rats were both upregulated in the MOX treatment group, compared to the untreated DOR model. Further, we found that the MOX group had reduced apoptosis of ovarian granulosa cells, increased Bcl-2 expression and reduced expression of Bax. Furthermore, the PI3K/AKT signaling pathway was triggered by the moxibustion treatment.@*CONCLUSION@#Moxibustion improved ovarian function and suppressed apoptosis of ovarian granulosa cells in a rat model of DOR induced by TGS, and the mechanism may involve the PI3K/AKT signaling pathway.

Metagenomic data-analysis reveals enrichment of lipopolysaccharide synthesis in the gut microbiota of atrial fibrillation patients / 中华心血管病杂志

Objective: To investigate the functional changes of key gut microbiota (GM) that produce lipopolysaccharide (LPS) in atrial fibrillation (AF) patients and to explore their potential role in the pathogenesis of AF. Methods: This was a prospective cross-sectional study. Patients with AF admitted to Beijing Chaoyang Hospital of Capital Medical University were enrolled from March 2016 to December 2018. Subjects with matched genetic backgrounds undergoing physical examination during the same period were selected as controls. Clinical baseline data and fecal samples were collected. Bacterial DNA was extracted and metagenomic sequencing was performed by using Illumina Novaseq. Based on metagenomic data, the relative abundances of KEGG Orthology (KO), enzymatic genes and species that harbored enzymatic genes were acquired. The key features were selected via the least absolute shrinkage and selection operator (LASSO) analysis. The role of GM-derived LPS biosynthetic feature in the development of AF was assessed by receiver operating characteristic (ROC) curve, partial least squares structural equation modeling (PLS-SEM) and logistic regression analysis. Results: Fifty nonvalvular AF patients (mean age: 66.0 (57.0, 71.3), 32 males(64%)) were enrolled as AF group. Fifty individuals (mean age 55.0 (50.5, 57.5), 41 males(82%)) were recruited as controls. Compared with the controls, AF patients showed a marked difference in the GM genes underlying LPS-biosynthesis, including 20 potential LPS-synthesis KO, 7 LPS-biosynthesis enzymatic genes and 89 species that were assigned as taxa harbored nine LPS-enzymatic genes. LASSO regression analysis showed that 5 KO, 3 enzymatic genes and 9 species could be selected to construct the KO, enzyme and species scoring system. Genes enriched in AF group included 2 KO (K02851 and K00972), 3 enzymatic genes (LpxH, LpxC and LpxK) and 7 species (Intestinibacter bartlettii、Ruminococcus sp. JC304、Coprococcus catus、uncultured Eubacterium sp.、Eubacterium sp. CAG:251、Anaerostipes hadrus、Dorea longicatena). ROC curve analysis revealed the predictive capacity of differential GM-derived LPS signatures to distinguish AF patients in terms of above KO, enzymatic and species scores: area under curve (AUC)=0.957, 95%CI: 0.918-0.995, AUC=0.940, 95%CI 0.889-0.991, AUC=0.972, 95%CI 0.948-0.997. PLS-SEM showed that changes in lipopolysaccharide-producing bacteria could be involved in the pathogenesis of AF. The key KO mediated 35.17% of the total effect of key bacteria on AF. After incorporating the clinical factors of AF, the KO score was positively associated with the significantly increased risk of AF (OR<0.001, 95%CI:<0.001-0.021, P<0.001). Conclusion: Microbes involved in LPS synthesis are enriched in the gut of AF patients, accompanied with up-regulated LPS synthesis function by encoding the LPS-enzymatic biosynthesis gene.

Clinical significance of telomerase reverse transcriptase promoter mutation in radioactive iodine refractory papillary thyroid cancer / 中华核医学与分子影像杂志

Objective:To evaluate the influence of telomerase reverse transcriptase (TERT) promoter mutation on radioiodine uptake status of radioactive iodine refractory papillary thyroid cancer (RAIR-PTC) and radioiodine therapy response by analyzing the mutation frequency of TERT promoter in RAIR-PTC.Methods:A total of 37 patients with RAIR-PTC (15 males, 22 females, age (49.8±16.1) years) and 40 PTC patients with effective radioiodine therapy (13 males, 27 females, age (39.8±10.9) years) between January 2005 and June 2020 in JiangYuan Hospital Affiliated to Jiangsu Institute of Nuclear Medicine were retrospectively analyzed. TERT promoter mutation and B-Raf proto-oncogene, serine/threonine kinase (BRAF) V600E mutation of patients were observed. The differences across genotype patterns on radioiodine uptake status and therapy response were compared. The Fisher′s exact test and independent-sample t test were used for data analysis. Results:The incidence rate of TERT promoter mutation in the RAIR-PTC group was 40.54% (15/37, all C228T), which was significantly higher than that in the effective radioiodine therapy group (0, 0/40; P<0.001). No statistically significant difference was found for the mutation rate of BRAF V600E between the RAIR group (64.86%, 24/37) and the effective radioiodine therapy group (72.50%, 29/40; P=0.858). Patients with TERT promoter mutation were older ( t=3.76, P=0.001) and the non-intake rate of radioiodine in distant metastases of those patients was higher ( P=0.037). Furthermore, 2/3 of patients who received targeted therapies and 3/4 deaths had TERT promoter mutation. Among 35 patients with negative thyroglobulin antibody (TgAb), 11/14 of patients with TERT mutation had a rising stimulated thyroglobulin (sTg), while the percentage of the non-TERT mutation group was 57.1% (12/21; P=0.357). Conclusion:The TERT promoter mutation rate is significantly increased in RAIR-PTC patients and can serve as a prognostic predictor in RAIR.

Progress on standardized nutrition therapy for head and neck cancer during the peri-radiotherapeutic period / 中华放射肿瘤学杂志

Malnutrition is a common complication of cancer patients, and solving nutrition problems is still one of the challenging tasks in clinical practice. The incidence of malnutrition in head and neck cancer patients during the peri-radiotherapeutic period is high, which is not only related to disease-mediated metabolic disorders, complications and psychological factors, but also associated with the toxic and side effects induced by radiotherapy. Malnutrition will reduce the tolerance, accuracy, and therapeutic effects of radiotherapy, which in turn lowers the quality of life and even adversely affects the prognosis of disease. Medical nutrition therapy can improve the nutritional status of the body, ensure smooth progress of radiotherapy, and improve the efficacy of comprehensive cancer treatment. It is necessary and urgent to deliver standardized nutrition therapy and management of head and neck cancer patients during the peri-radiotherapeutic period. Nutritional risk screening, nutritional assessment, and acute radiation injury assessment are required to develop an individualized nutrition treatment plan and make dynamic adjustment. In this article, relevant literature of nutrition therapy for head and neck radiotherapy at home and abroad was summarized, and the standardized nutrition therapy for head and neck cancer patients during the peri-radiotherapeutic period was reviewed.

Research Progress of Histone Deacetylase Inhibitor Combined with Immune Checkpoint Inhibitor in the Treatment of Tumor / 中国肺癌杂志

Immunotherapy is one of the main strategies of anti-tumor therapy at present, in which immune checkpoint inhibitors (ICIs) are the most widely used drug. ICIs resistance is mediated by a variety of cytokines and immune cells, and the mechanism is complex, which is the main reason for the failure of immunotherapy in cancer patients. Histone deacetylase inhibitor (HDACi), as a class of epigenetic regulatory drugs, plays an important role in regulating cell cycle, proliferation, differentiation, and activity. In recent years, Studies have found that HDACi can not only regulate cell biological characteristics, but also closely related to the improvement of tumor ICIs drug resistance. Therefore, the study on how HDACi enhances the efficacy of ICIs is of great significance to tumor immunotherapy. This article will review the research progress of HDACi combined with ICIs in treating malignant tumors and their related mechanism.

Study on iodine nutrition and related influencing factors of children aged 8-10 in Wuhan / 中国学校卫生

Objective@#To understand the status of iodine nutrition and its related influencing factors of school-age children in Wuhan, so as to provide the basis for adjusting the strategies of IDD prevention and control.@*Methods@#In 5 districts of Wuhan (Hongshan, Hanyang, Hannan, Jiangxia, Dongxihu), non-boarding students aged 8-10 years old were selected from each of the five sample areas in the east, west, south, north and middle. Samples of urine and the cooking salt from their home were randornly colleted among children. Height, weight measurement and a self-administered questionnaire were conducted at the same time. A total of 942 valid questionnaires were collected, including 484 boys and 458 girls.@*Results@#The median of iodine content of children s household salt was 23.20 mg/kg, the median of urinary iodine of children in the city was 251.00 μg/L. Children s random urine iodine concentration was related to gender, whether kelp was consumed the day before the survey, the frequency of consuming milk, and whether they received radiological examinations(P<0.05). Male (OR=1.38, 95%CI=1.04-1.82), consumption of kelp the day before the survey (OR=1.67,95%CI=1.13-2.47) and radiological examination (OR=1.26,95%CI=1.05-1.52) were risk factors for children with urinary iodine concentration higher than the upper limit of the appropriate value(P<0.05). The awareness rate of children s iodine deficiency disease prevention knowledge in Wuhan was 69.64%.@*Conclusion@#The iodine nutritional status of children aged 8-10 years in Wuhan was higher than the appropriate level recommended by international organizations. The random urine iodine concentration of children was affected by many factors and the awareness rate of children s iodine deficiency disease knowledge in Wuhan was low. Therefore, health education for children and residents on iodine deficiency disorders should be strengthened, and they should be properly guided and intervened to ensure that iodine deficiency is prevented while iodine excess is avoided.

The role of FGF21 in the pathogenesis of cardiovascular disease / 中华医学杂志(英文版)

The morbidity and mortality of cardiovascular diseases (CVDs) are increasing worldwide and seriously threaten human life and health. Fibroblast growth factor 21 (FGF21), a metabolic regulator, regulates glucose and lipid metabolism and may exert beneficial effects on the cardiovascular system. In recent years, FGF21 has been found to act directly on the cardiovascular system and may be used as an early biomarker of CVDs. The present review highlights the recent progress in understanding the relationship between FGF21 and CVDs including coronary heart disease, myocardial ischemia, cardiomyopathy, and heart failure and also explores the related mechanism of the cardioprotective effect of FGF21. FGF21 plays an important role in the prediction, treatment, and improvement of prognosis in CVDs. This cardioprotective effect of FGF21 may be achieved by preventing endothelial dysfunction and lipid accumulating, inhibiting cardiomyocyte apoptosis and regulating the associated oxidative stress, inflammation and autophagy. In conclusion, FGF21 is a promising target for the treatment of CVDs, however, its clinical application requires further clarification of the precise role of FGF21 in CVDs.

Abstract Introduction The types of allergic rhinitis are roughly classified based on the causative antigens, disease types, predilection time, and symptom severity. Objective To examine the clinical typing and individualized treatment approach for allergic rhinitis and to determine the optimal treatment method for this disease using various drug combination therapies. Methods A total of 108 participants with allergic rhinitis were divided into three groups based on symptoms. Subsequently, each group was further categorized into four subgroups based on the medications received. The efficacy of the treatments was evaluated using the visual analog scale VAS scores of the total and individual nasal symptoms, decline index of the symptom score, histamine and leukotriene levels, and mRNA and protein expression levels of histamine 1 and cysteinyl leukotriene 1 receptors. Results Loratadine + mometasone furoate and loratadine + mometasone furoate + montelukast significantly improved the sneezing symptom and reduced the histamine levels compared with the other combination therapies (p < 0.05). Meanwhile, montelukast + mometasone furoate and montelukast + mometasone furoate + loratadine considerably improved the nasal obstruction symptom and decreased the leukotriene D4 levels compared with the other combination therapies (p < 0.05). Conclusion Clinical symptom evaluation combined with experimental detection of histamine and leukotriene levels can be an objective and accurate method to clinically classify the allergic rhinitis types. Furthermore, individualized treatment based on allergic rhinitis classification can result in a good treatment efficacy.

Objective To discuss the clinical characteristics of adrenal metastases,and summarize the experience of diagnosis and treatment.Methods From January 2008 to June 2018,the clinical data of 55 patients with adrenal metastases treated in our hospital were analyzed retrospectively.This study included 34 male patients and 21 female patients and the median age was 60 years old (ranged 55 to 84 years old).The median value of maximum diameter of adrenal metastases was 3 cm (ranged 1.9 to 10.3 cm);with 35 cases on the left side,13 cases right and 7 cases bilateral.The primary sites of malignant tumors were pancreas (18 cases,32.7％),lung (12 cases,21.8％),liver (6 cases,10.9％) and colorectum (6 cases,10.9％),respectively.Thirty-four cases were confirmed by pathology after adrenalectomy and 21 cases were confirmed by needle biopsy.Thirty cases were diagnosed synchronously with the primary tumor and 25 cases were metachronous.The median time from diagnosis of primary tumors was 13.3 months (ranged 2.0 to 97.4 months).42 cases of these 55 cases were diagnosed within one year.Treatment options for adrenal metastatic lesions included single adrenalectomy in 18 cases,adrenalectomy combined with radiotherapy 16 cases,single intravenous chemotherapy 10 cases,intravenous chemotherapy combined with non-operative treatment 10 cases and single radiotherapy 1 case.Results The main pathological types were adenocarcinoma (19 cases,34.5％),ductal adenocarcinoma (10 cases,18.2％),hepatocellular carcinoma (6 cases,10.9％) and clear cell carcinoma (4 cases,7.3％).Two cases were lost follow-up and the follow-up rate was 96％,the median follow-up time was 8 months (ranged 1 to 135 months).The median overall survival (OS) time of 55 patients was 5.3 months (ranged 1 to 134 months).The one-year survival rate was 23.6％ (13/55),the two-year survival rate was 12.7％ (7/55),the three-year survival rate was 9.1％ (5/55) and the five-year survival rate was 1.8％ (1/55).Conclusions Pancreatic cancer was the most common type of malignant tumor for adrenal metastases in our hospital.Most primary tumors and adrenal metastases were diagnosed synchronously or within one year.Comprehensive treatment with retroperitoneal adrenalectomy may improve the OS,however the overall prognosis is poor.
