The purpose of the present overview of meta-analysis is to summarize and critically assess the effect of isoflavones and genistein on glucose metabolism among the peri- and post-menopausal women. Two independent authors searched the databases of MEDLINE, Scopus and Cochrane Library for meta-analysis. Three databases were searched from inception to January 2018. Methodological quality of each meta-analysis of randomized controlled trials was evaluated using the AMSTAR (a measurement tool used to assess systematic reviews). Four meta-analyses were included to the current overview. Fasting insulin levels and homeostatic model assessment of insulin resistance (HOMA-IR) values were significantly lower in peri-menopausal and postmenopausal. Two meta-analyses showed that treatment with isoflavones could not alter fasting blood glucose. However, one meta-analysis depicted that isoflavones significantly improved blood glucose levels in non-Asian postmenopausal women. Treatment with genistein could have significant beneficial effects on fasting insulin, blood glucose and HOMA-IR in comparison to the control group. Regardless of the population, the treatment with genistein is effective in improving fasting insulin, HOMA-IR and glucose levels. Nevertheless, the high heterogeneity among studies and poor methodology of reviews made it difficult to draw a definite conclusion on the positive impacts of soy on glucose metabolism.

BACKGROUND:
Progressive lipid loss of adipose tissue is a major feature of cancer-associated cachexia. In addition to systemic immune/inflammatory effects in response to tumor progression, tumor-secreted cachectic ligands also play essential roles in tumor-induced lipid loss. However, the mechanisms of tumor-adipose tissue interaction in lipid homeostasis are not fully understood.
METHODS:
The yki -gut tumors were induced in fruit flies. Lipid metabolic assays were performed to investigate the lipolysis level of different types of insulin-like growth factor binding protein-3 (IGFBP-3) treated cells. Immunoblotting was used to display phenotypes of tumor cells and adipocytes. Quantitative polymerase chain reaction (qPCR) analysis was carried out to examine the gene expression levels such as Acc1 , Acly , and Fasn et al .
RESULTS:
In this study, it was revealed that tumor-derived IGFBP-3 was an important ligand directly causing lipid loss in matured adipocytes. IGFBP-3, which is highly expressed in cachectic tumor cells, antagonized insulin/IGF-like signaling (IIS) and impaired the balance between lipolysis and lipogenesis in 3T3-L1 adipocytes. Conditioned medium from cachectic tumor cells, such as Capan-1 and C26 cells, contained excessive IGFBP-3 that potently induced lipolysis in adipocytes. Notably, neutralization of IGFBP-3 by neutralizing antibody in the conditioned medium of cachectic tumor cells significantly alleviated the lipolytic effect and restored lipid storage in adipocytes. Furthermore, cachectic tumor cells were resistant to IGFBP-3 inhibition of IIS, ensuring their escape from IGFBP-3-associated growth suppression. Finally, cachectic tumor-derived ImpL2, the IGFBP-3 homolog, also impaired lipid homeostasis of host cells in an established cancer-cachexia model in Drosophila . Most importantly, IGFBP-3 was highly expressed in cancer tissues in pancreatic and colorectal cancer patients, especially higher in the sera of cachectic cancer patients than non-cachexia cancer patients.
CONCLUSION
Our study demonstrates that tumor-derived IGFBP-3 plays a critical role in cachexia-associated lipid loss and could be a biomarker for diagnosis of cachexia in cancer patients.

Objective: To evaluate the consistency of mass spectrometry (MS) and chemiluminescence immunoassay (CLIA) in detecting serum insulin-like growth factor-1 (IGF-1) and IGF-1 standard deviation score (SDS). Methods: This cross-sectional parallel control study prospectively collected the serum samples of 115 children with short stature disorders who were admitted in the Department of Endocrinology, Beijing Children's Hospital, Capital Medical University from February 2020 to December 2021. The serum IGF-1 level was detected by CLIA and MS, and converted to SDS for consistency analysis. Pearson analysis was used to analyze the correlation between the 2 methods, and Deming regression equation was established. Bland-Altman diagram and weighted Kappa coefficient were used to evaluate the consistency of the 2 methods. Results: There were 46 boys (40.0%) and 69 girls (60.0%), aged (8±3) years. Among the 115 cases, 37 were Turner syndrome, 59 were small for gestational age (SGA) at term, 1 was growth hormone deficiency (GHD) and 18 were other diseases. Pearson correlation analysis showed a preferable correlation between IGF-1 measured by the 2 detection methods (r=0.94, P<0.01), and IGF-1 SDS was also significantly correlated (r=0.92, P<0.01). Bland-Altman analysis showed that the consistency of serum IGF-1 levels detected by the 2 methods was poor, and the mean difference between CLIA and MS was 33.38 μg/L. The result detected by CLIA was significantly higher than that by MS, with SDS of 43.51 μg/L (95%CI -51.89-118.7 μg/L). After converting the results to SDS and removing 3 outliers (including 1 GHD patient), the weighted Kappa showed acceptable consistency (κ=0.68). Conclusion: In clinical application, after converting to IGF-1 SDS, IGF-1 detected by MS and CLIA can be used for cross-reference, but too high or too low levels should be cautious about.

5.Switching from human insulin to biphasic insulin aspart 30 treatment gets more patients with type 2 diabetes to reach target glycosylated hemoglobin < 7%: the results from the China cohort of the PRESENT study.
Chinese Medical Journal 2010;123(9):1107-1111
BACKGROUNDThe clinical importance of glycaemic control in patients with diabetes has been well established. This study aimed to explore twice-daily biphasic insulin aspart 30 (BIAsp 30) for insulin initiation in patients with type 2 diabetes mellitus (T2DM) who had poor glycaemic control with human insulins (HIs). We use data from a Chinese cohort of the PRESENT study.
METHODSIn the 3-month study, Chinese subjects with T2DM started insulin therapy with BIAsp 30 in routine care. Glycaemic control was measured by glycosylated hemoglobin (HbA(1C)), fasting plasma glucose (FPG) and posting plasma glucose (PPG). The safety assessment included hypoglycaemia and other adverse events.
RESULTSA total of 1989 subjects previously treated with His were switched to BIAsp 30 for 3-month treatment. Mean HbA(1C), FPG and PPG were significantly improved after the therapy. The overall rate of hypoglycaemia decreased at the end of the trial except for the patients previously treated with long-acting insulin. Most of the events were minor and diurnal hypoglycaemia. Only one serious adverse drug reaction (SADR), a local hypersensitivity, was reported. The majority of the patients (> or = 96.7%) and physicians (> or = 84.7%) were either satisfied or very satisfied with the treatment using BIAsp 30 compared with previous HI therapy.
CONCLUSIONThe BIAsp 30 treatment improved both glycaemic control and patients' satisfaction without increasing hypoglycaemia in T2DM subjects inadequately controlled by His.

BACKGROUNDThe effectiveness and safety of initiating biphasic insulin aspart 30 in patients who were poorly controlled on oral glucose-lowering drugs were studied in randomized controlled trials, while results from clinical practice remain limited. This subgroup analysis was to provide such findings from a large-scale non-interventional study.
METHODSA1chieve was a multinational, prospective, open-label, non-interventional, 24-week study in patients with type 2 diabetes initiating insulin analogues in 28 countries across Asia, Africa, Europe, and Latin America. After physician had taken the decision to use this insulin, any patient with type 2 diabetes who was not treated with or who had started the study insulin within 4 weeks before inclusion was eligible. Patients were treated with study insulin alone or in combination with oral glucose-lowering drugs. Data on adverse drug reactions, hypoglycemia and glycemic control were collected at baseline, week 12 and 24. This is a report of a Chinese subgroup analysis from the A1chieve study.
RESULTSTotally, 4 100 patients constituted this subgroup. No serious adverse drug reactions were reported. Rates of total, major, nocturnal hypoglycemic events (events/patient per year) were 1.47, 0.10, 0.31 at baseline and 1.35, 0.00, 0.22 at week 24, respectively. Glycemic control was improved as measured by hemoglobin A1c (mean 9.3% to 7.0%, reduction -2.3%), fasting plasma glucose (mean 10.2 to 6.8 mmol/L, reduction -3.5 mmol/L) and postprandial plasma glucose (mean 14.4 to 8.8 mmol/L, reduction -5.6 mmol/L), all P < 0.001. Change in mean body weight was +0.3 kg (P < 0.001).
CONCLUSIONIn this subgroup analysis of the A1chieve study, biphasic insulin aspart 30 improved glycemic control with low risk of hypoglycemia.
