Objective:This study aimed to observe the clinical efficacy of implanting radioactive 125I seeds to treat non-small cell lung cancer (NSCLC) on the basis of the recent changes in serum tumor markers (including CEA, CA125, SCC-Ag, and CYFRA21-1). Methods:We selected 72 patients who were pathologically confirmed with NSCLC and received CT-guided percutaneous implantation of radioactive 125I seeds from January 2009 to June 2012. The concentration of the serum tumor markers was detected 3 d before implan-tation and 1, 2, 3, and 6 months after implantation. Result:All of the operations were successfully completed. One month after implan-tation, a significant change was observed in the concentration of serum tumor markers (CEA, CA125, SCC-Ag, and CYFRA21-1) com-pared with their preoperative levels (P<0.01). No significant difference was observed between the different time points after implanta-tion. Conclusion:The treatment of NSCLC by implanting radioactive 125I seeds can effectively reduce the level of tumor markers. A sig-nificant difference was observed in the level of tumor markers between patients with different efficacy classifications.

Objective To investigate the relationship between plasma levels of chromogranin A (CHGA) and adi-pose triglyceride lipase (ATGL) in patients with type 2 diabetes (T2DM) combined non-alcoholic fatty liver disease (NAFLD). Methods The plasma levels of CHGA and ATGL were assayed by enzyme-linked immunosorbent assay (ELISA) in T2DM patients with NAFLD (group A, n=74), T2DM without NAFLD (group B, n=76), and normal group (group NC, n=75). The correlation between CHGA, ATGL and other metabolic index was analyzed. Results The plasma level of CHGA was significantly higher in group A (83.15±9.46) and group B (70.90±2.75) than that of group NC (46.74±8.15, P<0.01), and the level of CHGA was significantly higher in group A than that of group B (P<0.01). The plasma level of ATGL was sig-nificantly lower in group A (21.36±13.42) and group B (40.29±22.83) than that of group NC (72.30±26.41, P<0.01), and the level was lower in group A than that of group B (P<0.01). There was a negative correlation between the plasma CHGA, AT-GL and carbohydrate oxidation rate in group A. There was a positive correlation between fasting insulin (FINS), insulin resis-tance index (HOMA-IR), free fatty acid (FFA) and fat oxidation rate in group A. There was a negative correlation between plasma level ATGL and body mass index (BMI), FINS, cholesterol (TC), triglyceride (TG) and HOMA-IR, meanwhile, it was positively correlated with FFA. The multiple stepwise regression analysis showed that FINS, ATGL and FFA were indepen-dent variables for CHGA. The Logistic regression analysis showed that plasma levels of CHGA, ATGL and FFA were the in-dependent predictors of T2DM with NAFLD. Conclusion The plasma levels of CHGA and ATGL are closely correlated with substance and energy metabolism, and the interaction between them may play an important role in the pathogenesis of T2DM with NAFLD .

Objective To investigate the relationship of omentin-1 with adiponectin and inflammatory cytokines in type 2 diabetes (T2DM) patients with nonalcoholic fatty liver disease (NAFLD). Methods The serum levels of omentin-1 and adiponectin were assayed by enzyme-linked immunosorbent assay (ELISA) in patients of T2DM with NAFLD (group A, n=63), T2DM without NAFLD (group B, n=63)and normal control group (group C, n=70). At the same time the biochemical markers and inflammatory marker, such as tumor necrosis factor (TNF)-α, high-sensitivity C-reactive protein (hs-CRP) and interleukin 6(IL-6) were detected in three groups. The correlation analysis and multiple regression analysis were used to de-tect the association of omentin-1 with adiponectin and inflammatory markers. The logistic regression was used to analyze fac-tors influencing NAFLD in patients with T2DM. Results The serum levels of omentin-1 and adiponectin were significant-ly lower in group A [ (27.02±2.82)μg/L and (11.98±3.63) mg/L] than those of group B [(31.52±2.81)μg/L and (15.85±3.28) mg/L] and group C [(35.92±2.80)μg/L and (19.88±3.44) mg/L], and there were significantly lower levels of them in group B than those of group C (P<0.01). The plasma omentin-1 level was positively correlated with adiponectin and high density li-poprotein (HDL-C) in group A. Also the plasma omentin-1 level was negatively correlated with TNF-α, IL-6, fasting blood glucose (FBG), homeostasis model assessment of insulin resistance (HOMA-IR), visceral adipose tissue, waist, waist-to-hip ratio (WHR) and free fatty acid in group A (P<0.05 or P<0.01). Multiple stepwise regression analysis showed that adipo-nectin, TNF-αand IL-6 were independent factors influencing the level of plasma omentin-1. Logistic regression analysis showed that omentin-1 was one of independent factors influencing T2DM combined with NAFLD (P<0.01). Conclusion The incident of NAFLD in T2DM patients is related to the lower level of omentin-1, which may be influenced by adiponectin and inflammatory factors.

One case of 46, XY partial gonadal dysgenesis due to a congenital defect of DEAH-box RNA helicase 37(DHX37) was reported. The clinical and genetic data of a boy who was admitted to the Department of Endocrinology and Metabolism, the First Affiliated Hospital of Henan University of Science and Technology due to ambiguous external genitalia in September 2020 were collected and analyzed. This 3-month-old male patient showed a micropenis, bilateral cryptorchidism, 46, XY karyotype, a decrease in testosterone, anti-Müllerian hormone, inhibin B, an increase in follicle stimulating hormone. Testis biopsy indicated gonadal dysgenesis. The proband harbored a de novo heterozygous mutation in the DHX37 gene c. 923G>A(p.Arg308Gln). DHX37 variants need to be considered for 46, XY gonadal dysgenesis.
