Objective To investigate the impact of lipoprotein lipase (LPL) gene Hind Ⅲ polymorphisms on plasma lipid and body adipose tissue distribution in simple obese patients. Methods The Hind Ⅲ site of LPL gene intron 8 was detennined by PCR-RFLP in 98 simple obese patients and 51 normal controls. Anthropometry and blood lipid levels were also measured. The parameters for regional adipose tissue distribution were measured by computerized tomography (CT). Results In both groups, H + was the major allele. There was no statistically significant difference in frequencies of genotypes or alleles between the two groups. In obese subjects, Hind Ⅲ H + H + genotype was associated with higher level of triglycerides and lower level of high density lipoprotein-cholesterol ( HDL-C) , as compared with the heterozygote (H + H - ) or homozygote ( H - H - ) genotypes (both P

Background::Links between alterations in gut microbiota composition and amyotrophic lateral sclerosis (ALS) have previously been reported. This study aimed to examine the microbiota in the nasal cavity of ALS.Methods::Sixty-six ALS patients and 40 healthy caregivers who live in close proximity with patients were enrolled. High throughput metagenomic sequencing of the 16S ribosomal deoxyribonucleic acid (rDNA) gene V3–V4 region of nasal microbiota was used to characterize the alpha and beta diversity and relative abundance of bacterial taxa, predict function, and conduct correlation analysis between specific taxa and clinical features.Results::The nasal microbiome of ALS patients showed lower alpha diversity than that of corresponding healthy family members. Genera Gaiella, Sphingomonas, Polaribacter_1, Lachnospiraceae_NK4A136_group, Klebsiella, and Alistipes were differentially enriched in ALS patients compared to controls. Nasal microbiota composition in ALS patients significantly differed from that in healthy subjects (unweighted UniFrac P = 0.001), while Linear discriminant analysis Effect Size (LEfSe) analysis indicated that Bacteroidetes and Firmicutes dominated healthy nasal communities at the phylum level, whereas Actinobacteria was the predominant phylum and Thermoleophilia was the predominant class in ALS patients. Genus Faecalibacterium and Alistipes were positively correlated with ALS functional rating scale revised (ALSFRS-R; rs = 0.349, P = 0.020 and rs = 0.393, P = 0.008), while Prevotella-9 and Bacteroides operational taxonomic units (OTUs) were positively associated with lung function (FVC) in ALS patients ( rs = 0.304, P = 0.045, and rs = 0.300, P = 0.048, respectively). Prevotella-1 was positively correlated with white blood cell counts (WBC, rs = 0.347, P = 0.021), neutrophil percentage (Neu%, rs = 0.428, P = 0.004), and neutrophil-to-lymphocyte ratio (NLR, rs = 0.411, P = 0.006), but negatively correlated with lymphocyte percentage (Lym%, rs = -0.408, P = 0.006). In contrast, Streptococcus was negatively associated with Neu% ( rs = -0.445, P = 0.003) and NLR ( rs = -0.436, P = 0.003), while positively associated with Lym% ( rs = 0.437, P = 0.003). No significant differences in nasal microbiota richness and evenness were detected among the severe and mild ALS patients. Conclusions::ALS is accompanied by altered nasal microbial community composition and diversity. The findings presented here highlight the need to understand how dysbiosis of nasal microbiota may contribute to the development of ALS.

Objective To analyze the efficacy and safety of glimepiride treatment as initial monotherapy in newly diagnosed patients with type 2 diabetes mellitus (T2DM).Methods This was a subgroup analysis of the GREAT study,which investigated the efficacy and safety of glimepiride as initial monotherapy in Chinese patients with T2DM.This analysis was performed in 209 patients with disease duration less than 6 months and never received any anti-diabetic drugs.The change of HbA1C,fasting plasm glucose (FPG),2 h postprandial blood glucose (2hPPG),homeostasis model assessment for β-cell function index (HOMA-β),homeostasis model assessment for insulin-resistance index(HOMA-IR),the percentage of patients with HbA1C ＜ 7.0％ at endpoint and the incidence of hypoglycemia were evaluated after 16-weeks treatment.Results After 16-weeks glimepiride treatment,HbA1C value reduced significantly from baseline to endpoint,the reduction was statistically significant (9.21％ ± 1.65％ to 6.69％±0.83％,P＜0.001),69.7％ of the patients achieved HbA1C ＜7.0％ at study endpoint.Glimepiride-treated patients also achieved a significant improvement in FPG [from (10.15 ± 2.13) mmol/L to (7.23 ± 1.50) mmol/L,P＜0.001] and 2hPPG [from (17.21 ±4.14) mmol/L to (11.62 ± 3.34) mmol/L].HOMA-β was improved from 17.21± 15.19 [11.62 (2.90,115.8)] to 41.13 ± 44.12 [28.00 (5.1,360.00)],and HOMA-IR was reduced from 2.32± 1.90 [1.76 (0.60,12.80)] to 2.07 ± 1.74 [1.63 (0.4,12.3)].The incidence of all reported symptomatic hypoglycemia was 18.2％,and the incidence of confirmed hypoglycemia was 3.8％.Conclusion This analysis showed that glimepiride treatment as an initial mono-therapy could effectively improve blood glucose control in newly diagnosed patients with T2DM,and the treatment may improve islet β cell function,and the safety profile is reasonably good.

Objective To compare the safety and efficacy of insulin degludec (IDeg) with those of insulin glargine (IGlar) in insulin-naive subjects with type 2 diabetes (T2DM).Methods This was a 26-week,randomized,open-label,parallel-group,treat-to-target trial in 560 Chinese subjects with T2DM (men/women:274/263,mean age 56 years,mean diabetes duration 7 years) inadequately controlled on oral antidiabetic drugs (OADs).Subjects were randomized 2:1 to once-daily IDeg (373 subjects) or IGlar(187 subjects),both in combination with metformin.The primary endpoint was changes from baseline in glycosylated hemoglobin(HbA1c) after 26 weeks.Results Mean HbA1c decreased from 8.2％ in both groups to 6.9％ in IDeg and 7.0％ in IGlar,respectively.Estimated treatment difference (ETD) of IDegIGlar in change from baseline was-0.10％ points (95％ CI-0.25-0.05).The proportion of subjects achieving HbA1c ＜ 7.0％ was 56.3％ and 49.7％ with IDeg and IGlar,respectively [estimated odds ratio of IDeg/IGlar:1.26 (95 ％ CI 0.88-1.82)].Numerically lower rateof overall confirmed hypoglycaemia and statistically significantly lower nocturnal confirmed hypoglycemia were associated with IDeg compared with IGlar,respectively [estimated rateratio of IDeg/IGlar 0.69 (95％ CI 0.46-1.03),and 0.43 (95％ CI 0.19-0.97)].No differences in other safety parameters were found between the two groups.Conclusions IDeg was non-inferior to IGlar in terms of glycaemic control,and was associated with a statistically significantly lower rate of nocturnal confirmed hypoglycaemia.IDeg is considered to be suitable for initiating insulin therapy in Chinese T2DM patients on OADs requiring intensified treatment.Clinical trail registration Clinicaltrials.gov,NCT01849289.
