Objective: To explore the glycemic control of newly-diagnosed type 2 diabetes with different levels of baseline body mass index (BMI) after 6 months treatment under the standardized metabolic disease management model. Methods: (1) 163 patients of newly-diagnosed type 2 diabetes were divided into normal weight (BMI 18.5-23.9 kg/m²), overweight (BMI 24.0-27.9 kg/m²), and obese (BMI≥28 kg/m²) groups according to baseline BMI, the blood glucose and lipids levels were compared among 3 groups. (2) The blood glucose levels were compared among 3 groups after 6 months of standardized management. (3) The overweight and obese patients were divided into group weight loss≥5% and group weight loss<5% or weight gain in 6 months. The blood glucose levels were compared. Results: (1) At baseline, overweight and obese groups had higher homeostasis model assessment for insulin resistance and lower high density lipoprotein-cholesterol compared with normal weight group. (2) After 6 months of treatment, HbA_1C and HbA_1C reduction showed no difference among 3 groups (normal, overweight and obese) after adjusted by baseline HbA_1C. The rate of HbA_1C<7% among 3 groups were 77.78%, 83.95%, and 80.43% (P>0.05). (3) After 6 months of treatment, 32.28% overweight and obese patients lost weight by ≥ 5%, while HbA_1Cand HbA_1Creduction showed no difference between 2 groups (weight loss≥5% and weight gain or weight loss<5%) after adjusted by baseline HbA_1C. Both groups achieved good glycemic control [(6.27±1.38 vs 6.43±0.66)%], but have no significantly(P>0.05). Group weight loss≥5% had better glucose control (92.68% vs 77.91%, P<0.05). Conclusions As BMI increased, insulin resistance and lipid disorders were more serious in newly-diagnosed type 2 diabetes. After 6 months of standardized metabolic management, newly-diagnosed type 2 diabetes with different baseline BMI and weight changes both achieved good glycemic control. In addition, patients losing weight equal to or more than 5% achieved higher attainment of HbA_1C targets.

BACKGROUND:Overactive osteoclasts disrupt bone homeostasis and play a bad role in the pathological mechanisms of related skeletal diseases,such as osteoporosis,fragility fractures,and osteoarthritis.Studies have confirmed that ellagic acid and ellagtannin have the potential to inhibit osteoclast differentiation.As their natural metabolites,urolithin A has antioxidant,anti-inflammatory,anti-proliferative and anti-cancer effects,but its effect on osteoclast differentiation and its underlying molecular mechanisms remain unclear. OBJECTIVE:To explore the effect of urolithin A on osteoclast differentiation induced by receptor activator for nuclear factor-κB ligand and its mechanism. METHODS:Mouse mononuclear macrophage leukemia cells(RAW264.7)that grew stably were cultured in vitro.Toxicity of urolithin A(0,0.1,0.5,1.5,2.5 μmol/L)to RAW264.7 cells were detected by cytotoxic MTS assay to screen out the safe concentration.Different concentrations of urolithin A were used again to intervene with receptor activator for nuclear factor-κB ligand-induced differentiation of RAW264.7 cells in vitro.Then,tartrate-resistant acid phosphatase staining and F-actin ring and nucleus staining were performed to observe its effect on the formation and function of osteoclasts.Finally,the expressions of urolithin A on upstream and downstream genes and proteins in the MAPK signaling pathway were observed by western blot and RT-qPCR assays. RESULTS AND CONCLUSION:Urolithin A inhibited osteoclast differentiation and F-actin ring formation in a concentration-dependent manner and 2.5 μmol/L had the strongest inhibitory effect.Urolithin A inhibited the mRNA expression of Nfatc1,Ctsk,Mmp9 and Atp6v0d2 and the protein synthesis of Nfatc1 and Ctsk,related to osteoclast formation and bone resorption.Urolithin A inhibited the activity of osteoclasts by downregulating the phosphorylation of p38 protein to inhibit the mitogen-activated protein kinase signaling pathway.

BACKGROUND: Plasma epidermal growth factor receptor (EGFR) mutation tests are less invasive than tissue EGFR mutation tests. We determined which of two kits is more efficient: cobas EGFR Mutation test v2 (cobasv2; Roche Molecular Systems, Pleasanton, CA, USA) or PANAMutyper-R-EGFR (Mutyper; Panagene, Daejeon, Korea). We also evaluated whether pleural effusion supernatant (PE-SUP) samples are assayable, similar to plasma samples, using these two kits. METHODS: We analyzed 156 plasma and PE-SUP samples (31 paired samples) from 116 individuals. We compared the kits in terms of accuracy, assessed genotype concordance (weighted κ with 95% confidence intervals), and calculated Spearman's rho between semi-quantitatively measured EGFR-mutant levels (SQIs) measured by each kit. We also compared sensitivity using 47 EGFR-mutant harboring samples divided into more-dilute and less-dilute samples (dilution ratio: ≥ or <1:1,000). RESULTS: cobasv2 tended to have higher accuracy than Mutyper (73% vs 69%, P=0.53), and PE-SUP samples had significantly higher accuracy than plasma samples (97% vs 55–71%) for both kits. Genotype concordance was 98% (κ=0.92, 0.88–0.96). SQIs showed strong positive correlations (P<0.0001). In less-dilute samples, accuracy and sensitivity did not differ significantly between kits. In more-dilute samples, cobasv2 tended to have higher sensitivity than Mutyper (43% vs 20%, P=0.07). CONCLUSIONS: The kits have similar performance in terms of EGFR mutation detection and semi-quantification in plasma and PE-SUP samples. cobasv2 tends to outperform Mutyper in detecting less-abundant EGFR-mutants. PE-SUP samples are assayable using either kit.

Lymphocytic hypophysitis(LYH) is a rare autoimmune inflammatory disorder of the pituitary gland, usually affecting young women in late pregnancy or postpartum period. To enhance the knowledge of LYH, herein we reported a case of LYH in a female during postpartum who presented with pituitary crisis.

ERK1/2 is a key protein that mediates cell signal transduction, and it is involved in regulating biological processes such as chromatin remodeling, nuclear disintegration, proliferation, survival, metabolism, and cell migration and differentiation. Its overactivation is closely related to the occurrence and progression of cancer, and the mechanism is manifested as the overactivation of ERK1/2 by gene mutations of upstream pathway molecules or regulators and the reactivation of ERK1/2 after inhibition against the above targets. ERK1/2 is a potentially valuable target. In this review, the mechanism of post-translational modification and spatial regulation of ERK1/2 and the application status of corresponding small-molecule inhibitors were discussed. The current antitumor strategy of targeting and regulating ERK1/2 was summarized, and the possibility of exploring potential targets was elucidated, thus providing new insights into the developmental research of ERK1/2 as an ideal anticancer target.

Objective To investigate the microRNA ( miRNA ) expression level of peripheral blood mononuclear cell ( PBMC) in autoimmune diabetes mellitus ( ADM) which includes type 1 diabetes mellitus ( T1DM) and latent autoimmune diabetes in adults ( LADA ) , T2DM patients, and matched healthy individuals. Methods Patients of T1DM, LADA, and T2DM were recruited in the Second Xiangya Hospital of Central South University from January 2015 to December 2016. The subjects were divided into two groups. The first group was used for high-throughput screening of differentially expressed microRNAs. The second group was used to validate the expression of miR-142-5p and miR-143-3p by real-time quantitative polymerase chain reaction (RT-qPCR). Results (1)The different miRNA expression patterns of PBMC were found among T1DM patients, LADA patients, T2DM patients, and health individuals. ( 2) Compared with T2DM patients and healthy controls, LADA and T1DM patients had down-regulated PBMC miR-142-5p expression, and up-regulated miR-143-3p expression. (3)RT-qPCR validation showed that the expression of miR-142-5p in LADA patients was significantly lower than that in T2DM patients (0.30±0.24 vs 1.33 ± 1.29, P<0.05) . The expression of miR-143-3p in T1DM and LADA was higher than that in T2DM and health individuals. However, no significant differences were found. Conclusion The miRNA expression patterns are different in the PBMC of T1DM patients, LADA patients, T2DM patients, and healthy individuals; the abnormal expressions of miR-142-5p and miR-143-3p may participate in the development of ADM by affecting apoptosis and immune cell differentiation.

Objective To study the implementation effects of China′s contracted service policy for family physicians. Methods Systematic evaluation method was used to extract, describe and analyze the literature information of the research on the implementation effect of family physicians contracted service policy. Results A total of 80 papers of four types were rounded up, including 47 on the effect of health management on patients with chronic diseases, 11 on the effect of health management on the elderly, 15 on the effect on the first diagnosis in the community, and 7 on the effect on the control of medical expenses.The research is mostly distributed in the developed areas in the east. The family physicians contracted service promotes the health management effect of patients with chronic diseases and the elderlies, improves the first visit ratio of residents at their community, and effectively controls the medical expenses.Existing research shows that such a service has achieved initial success.However, the research also identified such common problems as the shortage and low competence of family physicians, low quality, resource integration and inadequate policy publicity. Conclusions The contracted service policy in China has begun to play the role of " health gatekeeper" and " cost gatekeeper" to some extent.It is suggested to strengthen the training of general practitioners, establish and perfect incentive mechanism, and improve the construction of information platform, while the implementation effect of contracted services for family physicians deserve further study in a broader scope, deeper level and design specifications.
