Relationship between skeletal muscle mass index and metabolic phenotypes of obesity in adolescents / 中国当代儿科杂志

OBJECTIVES@#To study the relationship between skeletal muscle mass index (SMI) and metabolic phenotypes of obesity in adolescents, and to provide a basis for the prevention and control of adolescent obesity and related metabolic diseases.@*METHODS@#A total of 1 352 adolescents aged 12 to 18 years were randomly selected by stratified cluster sampling in Yinchuan City from October 2017 to September 2020, and they were surveyed using questionnaires, physical measurements, body composition measurements, and laboratory tests. According to the diagnostic criteria for metabolic abnormalities and the definition of obesity based on the body mass index, the subjects were divided into four metabolic phenotypes: metabolically healthy normal weight, metabolically healthy obesity, metabolically unhealthy normal weight, and metabolically unhealthy obesity. The association between SMI and the metabolic phenotypes was analyzed using multivariate logistic regression.@*RESULTS@#The SMI level in the metabolically unhealthy normal weight, metabolically healthy obesity, and metabolically unhealthy obesity groups was lower than that in the metabolically healthy normal weight group (P<0.001). Multivariate logistic regression analysis showed that after adjusting for gender and age, a higher SMI level was a protective factors for adolescents to develop metabolic unhealthy normal weight, metabolically healthy obesity, and metabolically unhealthy obesity phenotypes (OR=0.74, 0.60, and 0.54, respectively; P<0.001).@*CONCLUSIONS@#Increasing SMI can reduce the risk of the development of metabolic unhealthy/obesity.

Quality study of Prunellae spica dispensing granules based on standard decoction / 国际中医中药杂志

Objective:To establish the quality evaluation method of Prunellae spica dispensing granules based on three quality indexes of standard decoction. Methods:Fourteen batches of Prunellae spica were collected from different habitats. According to technical requirements, fourteen batches of Prunellae spica standard decoction and three batches of formula granules were prepared and the paste-forming rates were calculated. The fingerprints of Prunellae spica standard decoction and formula granules were established by Ultra High Performance Liquid Chromatography (UPLC). The similarity values of fingerprints between dispensing granules and standard decoction were calculated. The content and transferring rate of Rosmarinic acid were determined and calculated. Results:The average paste-forming rate of Prunellae spica was (12.59±2.32)%. The paste-forming rates of the three batches were 11.14%, 10.78% and 10.39% respectively. The average content of Rosmarinic acid in standard decoction was (18.99±9.74)mg/g. The average transferring rate was (60.58±7.87)%. The contents of three batches were 7.40 mg/g, 7.49 mg/g and 7.09 mg/g. The transferring rates were 52.06%, 50.10% and 50.40% respectively. Nine common fingerprint peaks were identified in the fingerprints of standard decoction and formula granules, two of which were identified as Rosmarinic acid and Caffeic acid by comparison of reference substance. The fingerprints similarity of Prunellae spica dispensing granules and standard decoction were 0.954, 0.973 and 0.952, respectively. Conclusions:The quality indexes of three batches of formulation granules are consistent with standard decoction. This method could provide reference for the establishment of quality standard of Prunellae spica dispensing granules.

Mechanism of rhein inhibition of colorectal cancer through arginine metabolism based on protein chip / 药学学报

Rhein is an anthraquinone compound extracted from rhubarb, aloe vera, Polygonum multiflorum. In this study, we screened the potential targets of rhein through protein chip technology and investigated the underlying mechanism of its inhibition of colorectal cancer. Colony formation assay and scratch assay were used to examine the effect of rhein on the proliferation and migration abilities of HCT116 cell; KEGG and protein interaction analyses of rhein specific binding proteins by screening rhein binding proteins using protein chip; qRT-PCR and Western blot assays were used to determine the effect of rhein on the expression levels of BCL-2-associated X protein (BAX), B-cell lymphoma-2 (BCL-2) and argininosuccinate synthetase 1 (ASS1) in HCT116 cell. The antitumor effect of rhein was verified by azoxymethane combined with dextran sodium sulfate (AOM/DSS) induced colorectal cancer model. Experimental animal procedures were performed in accordance with animal welfare and the standards of the Laboratory Animal Ethics Committee of South China Agricultural University, with approval from the ethics committee. In vivo and in vitro results indicate that rhein specific binding proteins are mainly involved in amino acid anabolism, especially the arginine anabolic signaling pathway. Rhein inhibited the proliferation and migration of HCT116 cell in a concentration-dependent manner. Treated with rhein for 24 h significantly enhanced the expression of BAX and ASS1 in HCT116 cells, as well as the level of nitric oxide (NO) metabolism. In a mouse model of colorectal cancer, rhein significantly alleviated AOM/DSS induced weight loss and reduced fecal occult blood score. Meanwhile, rhein enhanced BAX and ASS1 expression in colon tumor tissue, as well as increased arginine and NO in serum. IHC and HE stain indicated that rhein alleviated Ki67 expression and macrophage infiltration in the colonic tissue of mice with AOM/DSS and delayed tumor formation. In conclusion, rhein can exert antitumor activity by regulating arginine and NO metabolism through ASS1.

Diagnosis and treatment for emphysematous pyelonephritis: analysis of 14 cases from a single centre / 中华外科杂志

Objective: To examine the modalities of treatment and clinical outcomes of emphysematous pyelonephritis (EPN), in order to improve the survival rate of EPN patients. Methods: Totally 14 patients diagnosed as EPN between October 2011 and November 2020 at Department of Urology, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine were included in this article. Data collection including patient demographics, clinical manifestations, management and clinical outcomes were conducted by retrospective charts review, after receiving the institutional review board's approval. There were 11 females and 3 males with a median age of 59 years (range: 52 to 73 years). The lesions were located on the left side in 10 patients and right side in 4 patients. All the 14 patients suffered from fever, and present with severe sepsis or septic shock. The median time from symptom onset to admission to hospital was 3 days(range: 2 to 5 days). All cases had diabetes mellitus. Escherichia coli was the most common organism been cultured (11 cases), while Klebsiella pneumonia was the second (3 cases). CT scan showed bubbly or located gas in the renal parenchyma in 5 cases and presence of steaky or mottled gas in the renal parenchyma in 9 cases. All patients had been admitted to ICU for anti-septic shock therapy. Three patients had undergone percutaneous catheter drainage along with broad-spectrum antibiotics therapy while 3 patients had immediate nephrectomy, the other 8 cases had a combination of an initial percutaneous catheter drainage and second stage nephrectomy. Results: In this case series, 3 patients were died from EPN while the other 11 were survived. The median ICU stay time was 6 days (range: 3 to 11 days). Of the 3 patients died from EPN, 2 had undergone percutaneous catheter drainage along and 1 had received immediate nephrectomy. Among the 11 patients who were survived, only 1 had received percutaneous catheter drainage while the other 10 received nephrectomy (8 patients had staged nephrectomy). Follow-up was performed 6 months after discharge. Of the 11 surviving patients, 2 were lost to follow-up, and the remaining 9 patients had an creatine level of (118.4±29.4) μmol/L (range: 89 to 176 μmol/L). Conclusions: For patients coupled with diabetes who were initially diagnosed as acute pyelonephritis, the possibility of EPN should be considered when the disease progressed rapidly especially septic shock occurred. On the basis of empirical broad-spectrum antibiotics therapy and standardized anti-septic shock treatment, a combination of an initial percutaneous catheter drainage and second stage nephrectomy could be efficacious.

Analysis of acupoint-symptom relationship in CHENG Dan-an's Note About Treatise on Cold-Attack based on complex network / 中国针灸

Acupoint-symptom relationship in CHENG Dan-an's Note About Treatise on Cold-Attack was analyzed based on complex network, acupoint names and indications were extracted from the book, which provided ideas and methods for promoting the modernization of acupuncture and moxibustion by using complex network technology. A total of 112 acupoints in 201 acupuncture prescriptions were included, and the total frequency of acupoints was 880 times, forming 42 034 acupoint pairs. In terms of network indexes, compared with the complex network of comprehensive acupuncture books, such as Meridian and Acupoint Science, Zhenjiu Dacheng, Acupuncture A and B Meridians formed based on the same mathematical method, the complex network model for CHENG Dan-an's Note About Treatise on Cold-Attack shows more typical small world effect, which is characterized by higher network density (6.762) and shorter average path length (1.064). This phenomenon may be related to the tongue and pulse which added the link between acupoints. For the node indexes, the analysis of topological indexes such as Page Rank shows that acupoints represented by Dazhui (GV 14) has higher compatibility value in the treatment of exogenous diseases, which further demonstrates the clinical value of eigenvector centrality in guiding intelligent compatibility of points.

Resistance to apoptosis should not be taken as a hallmark of cancer / 癌症

In the research community, resistance to apoptosis is often considered a hallmark of cancer. However, pathologists who diagnose cancer via microscope often see the opposite. Indeed, increased apoptosis and mitosis are usually observed simultaneously in cancerous lesions. Studies have shown that increased apoptosis is associated with cancer aggressiveness and poor clinical outcome. Furthermore, overexpression of Bcl-2, an antiapoptotic protein, is linked with better survival of cancer patients. Conversely, Bax, CD95, Caspase-3, and other apoptosis-inducing proteins have been found to promote carcinogenesis. This notion of the role of apoptosis in cancer is not new; cancer cells were found to be short-lived 88 years ago. Given these observations, resistance to apoptosis should not be considered a hallmark of cancer.

Association of depression with inflammation in hospitalized patients of myocardial Infarction

The aim of this study was to examine the associations between depression and inflammatory markers in patients admitted to the hospital for myocardial infarction. Inflammatory cytokines, including high-sensitivity C-reactive protein [hs-CRP], interleukin [IL]-1beta, IL-6, and tumor necrosis factor-alpha [TNF-alpha] were assessed in a group of 75 depressed participants [score of >/= 12] and compared to a control group of 75 nondepressed participants [score < 12], all who had been admitted to the hospital for myocardial infarction. The presence of depressive symptoms was assessed using the Beck Depressive Symptoms Inventory II Scale [BDI-II]. Depressed myocardial infarction participants had significantly greater levels of TNF-alpha [t = 2.070, P < 0.05] compared with control myocardial infarction participants. The BDI-II score was positively correlated with TNF-alpha levels [r = 0.222, P < 0.05]. These results indicate that the presence of depressive symptoms is positively associated with TNF-alpha levels among patients who have suffered from myocardial infarction

Progression in metastasis of colorectal carcinoma / 浙江大学学报·医学版

Globally, the incidence of colorectal carcinoma (CRC) ranks the third among all cancers. The incidence of CRC is continually increasing in China. Invasion and metastasis are the major causes of death. Metastasis is a complex multistep malignant process, including the detachment of tumor cells from the primary site, interaction of tumor cells with the surrounding extracellular matrix, entering into the circulation or lymph system, adhesion to the endothelial cells of vascular wall, migration of tumor cells into secondary sites, angiogenesis and formation of new metastases. This article reviews the recent research progress in aspects of the metastasis related genes, microRNAs, epithelial mesenchymal transition, tumor stem cells, and micro environment of colorectal cancer.
