Objective:To investigate different sleep duration and glucose and lipid metabolism levels in residents of a community in Urumqi.Methods:Using the 2 049 residents′ data of chronic metabolic disease in a community of Urumqi collected in May 2017, 1 822 subjects aged between 19-80 years with complete information were enrolled, their blood pressure, waist circumference, height, weight, body mass index were measured and recorded. Using oral glucose tolerance test to measure fasting and 2 h after meal plasma glucose, uric acid, HbA 1C, total cholesterol, triglyceride, low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C) levels were all tested. Results:(1)There were 363 (19.9%), 1 349 (74.0%), and 110 (6.1%) respondents with sleep time≤6.0, 6.1 to 8.0, and>8.0 h/d, respectively. There were statistically significant differences in age, education, and family income in groups with different sleep time ( P<0.05), while their gender, smoking status, and exercise status were not statistically significant ( P>0.05). The rates of overweight, obesity, abdominal obesity, high uric acid, and hypertension in people with different sleep durations were statistically different ( P<0.01). The rates of the above indicators were higher in the group of sleep time≤6.0 h/d than the other two groups. (2) Differences in diastolic blood pressure, systolic blood pressure, body mass index, abdominal circumference, total cholesterol, and LDL-C levels were statistically significant among different sleep duration groups ( P<0.05). Further comparisons of the above indicators among three groups with different sleep durations were performed ( P<0.05). The levels of the above indicators in the sleep time≤6.0 h/d group were higher than those in the other two groups. There were no significant differences in fasting blood glucose, glycated hemoglobin, uric acid, triglyceride, and HDL-C among the three groups. (3) Multivariate logistic regression analysis showed that groups whether or not adjusted of age, family income, and education level, sleep time≤6.0 h/d was related to abdominal obesity, and sleep time≤6.0 h/d was be a risk factor for abdominal obesity [Unadjusted: OR=1.48(95% CI1.04-2.08); Adjusted: OR=1.65(95% CI1.18-2.32; P<0.05]. Conclusion:Sleep time ≤6.0 h/d is associated with abdominal obesity, and sleep time≤6.0 h/d may be a risk factor for abdominal obesity.

Objective:To observe the therapeutic effect of echinacoside (ECH) on liver injury and glucose metabolism disorder in sepsis rats induced by cecal ligation and puncture (CLP), and to explore its possible mechanism.Methods:Forty eight male Sprague Dawley (SD) rats were randomly divided into four groups: sham group (sham), model group (CLP), treatment group (CLP+ ECH) and inhibitor group (CLP+ ECH+ EX527). The sham group only received laparotomy, and the model group underwent CLP. The treatment group was intragastric administration of echinacea (30 mg/kg) every day after CLP modeling. The inhibitor group was injected with silence information regulator 1 (SIRT1) inhibitor EX527 (5 mg/kg) one hour before CLP, and then treated the same as the treatment group. Fasting blood glucose, insulin and serum biochemical indexes were detected in virous groups. The serum levels of interleukin (IL)-1 β, IL-6 and tumor necrosis factor-α(TNF-α) were detected by enzyme-linked immunosorbent assay (ELISA). 2′, 7′- dichlorofluorescein diacetate (DCFH-DA) staining was used to observe the production of reactive oxygen species (ROS) in liver tissue of rats in each group; hematoxylin-eosin (HE) staining was used to observe the pathological changes of liver tissue in each group; The expressions of SIRT1, glucose-6-phosphatase (G6Pase), phosphoenolpyruvate carboxykinase (PEPCK), phosphorylated signal transducers and activators of transcription 3 (p-STAT3) and phosphorylated protein ki-nase B(p-AKT) were detected by Western blot.Results:Compared with sham group, the levels of serum glucose, serum insulin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), ROS, IL-1β, IL-6 and TNF-α in model group increased, while the liver glycogen and survival rate decreased (all P<0.05). After echinacoside treatment, the serum glucose, serum insulin, ALT, AST, ROS , IL-1β, IL-6 and TNF-α levels decreased, and the liver glycogen and survival rate increased (all P<0.05); After SIRT1 inhibitor intervention, the levels of serum insulin, ALT, AST, IL-6 and ROS in the inhibitor group increased ( P<0.05). HE staining showed that there were infiltration and necrosis of inflammatory cells in the liver tissue of model group, and echinacoside could significantly reduce the focal and massive necrosis; Western blot showed that compared with the sham group, the expression levels of SIRT1, p-STAT3 and p-AKT protein in the model group decreased, while the expression levels of G6Pase and PEPCK protein increased ( P<0.05); After echinacoside treatment, the expression levels of SIRT1, p-STAT3 and p-AKT increased, while the expression levels of G6Pase and PEPCK decreased ( P<0.05). After SIRT1 inhibitor intervention, the expression of SIRT1, p-STAT3 and p-AKT protein decreased, and the expression of G6Pase and PEPCK protein increased in the inhibitor group ( P<0.05). Conclusions:Echinacoside is a potential therapeutic agent for sepsis associated liver injury and glucose metabolism disorders, which may play a role by targeting SIRT1 to activate STAT3 and AKT in the liver.

Objective:To investigate whether miRNA-296-5p can inhibit enterovirus 71 (EV71) virus replication in neural cells SK-N-SH by targeting the phosphatase and tensin homology deleted on chromosome 10 (PTEN)/phosphatidylinositol 3-kinase (PI3K)/serine/threonine kinases (AKT) signaling pathway.Methods:Serum samples were collected from patients with EV71 virus-infected hand-foot-mouth disease and normal physical examination, and the expressions of serum inflammatory factors procalcitonin (PCT), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) , interleukin-6 (IL-6), IL-1β, and IL-13 were detected by enzymelinked immunosorbent assay (ELISA). Human neuroblastoma SK-N-SH cells infected by EV71 virus in logarithmic growth phase were set up as control group, miRNA-296-5p mimic group and miRNA-296-5p inhibitor group. The transfection was carried out according to the Lipofectamine 2000tm cell transfection reagent. The expression of EV71-VP1 gene mRNA and protein and PTEN/PI3K/Akt signal pathway related molecules in three groups of cells was observed by real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) and Western blot.Results:ELISA test results showed that the levels of serum inflammatory factors PCT, CRP, TNF-α, IL-1β, IL-6 and IL-13 in patients with EV71 virus-infected hand, foot and mouth disease were significantly higher than those in normal physical examination ( P<0.05). The results of qRT-PCR and Western blot showed that the mRNA and protein levels of mirna-296-5p and PTEN in SK-N-SH were significantly decreased after EV71 virus infection, while the mRNA and protein levels of EV71-VP1 and molecules related to PI3K/AKT signaling pathway were significantly increased ( P<0.05). The expression of PTEN was significantly increased in the miRNA-296-5p mimic group, and the expression of EV71-VP1 and the activation of the PI3K/AKT signaling pathway were inhibited, while the effect was reversed in the miRNA-296-5p inhibitor group ( P<0.05). Conclusions:MiRNA-296-5p inhibits the replication of EV71 virus in neural cells SK-N-SH by targeting the PTEN/PI3K/AKT signaling pathway, while reducing the cellular inflammatory response, targeting miRNA-296-5p and downstream PTEN/PI3K/AKT The signal pathway is expected to provide therapeutic targets and theoretical basis for the treatment of hand-foot-mouth disease caused by clinical EV71 virus.

Objective:To observe the dynamic changes of thyroid hormone levels and thyroid autoimmune antibodies in pregnant women in Xinjiang Uygur Autonomous Region during pregnancy, and to investigate the significance of repeated screening of thyroid function in different gestational ages.Methods:A retrospective study was carried out of pregnant women who completed thyroid function screening in Clinic, People's Hospital of Xinjiang Uygur Autonomous Region from January 2015 to December 2017, and the test results of thyroid stimulating hormone (TSH), free thyroxine (FT 4), free triiodothyronine (FT 3), thyroid peroxidase antibody (TPOAb), and anti-thyroglobulin antibody (TGAb) were collected and analyzed of their changes during pregnancy. Pregnant women were divided into 2 different gestational age groups by the age limit of 30, the changes of thyroid dysfunction rate with pregnancy were analyzed, and the clinical significance of repeated screening in different pregnancy stages was discussed. Results:Changes of thyroid-related indicators with pregnancy: first, second, and third trimesters were 404,725, and 767 cases, respectively; TSH level in the third trimester (2.76 mU/L) was significantly higher than those in the first and second trimesters (2.55, 2.36 mU/L, P < 0.05), there was no significant difference between the first trimester and the second trimester ( P > 0.05); the FT 4 and FT 3 levels decreased gradually with pregnancy ( P < 0.05); the positive rate of TPOAb was significantly higher in the first and second trimesters than that in the third trimester ( P < 0.05), there was no significant difference between the first trimester and the second trimester ( P > 0.05); the positive rate of TGAb decreased gradually with pregnancy ( P < 0.05). Comparison of abnormal rate of TSH in different gestational ages: the first, second, and third trimesters were 352, 664, 735 cases, respectively; the abnormal rate of TSH in the overall study was statistically significant at different stages of pregnancy (χ 2=31.627, P < 0.05), the first trimester was significantly higher those in the second and third trimesters ( P < 0.05). In pregnant women aged ≥30 years old, the abnormal rate of TSH in the first trimester was significantly higher than those in the second and third trimesters ( P < 0.05); in pregnant women aged < 30 years old, the abnormal rate of TSH in the first trimester was significantly higher than that in the third trimester ( P < 0.05). There were no significant differences in the abnormal rate of TSH in the first, second, and third trimesters between the < 30 years old group and ≥30 years old group ( P > 0.05). Comparison of abnormal rate of FT 4 in different gestational ages: there were no significant differences in the FT 4 abnormal rate among different pregnancy groups in the overall, < 30, ≥30 years old groups (P > 0.05). In early pregnancy, the abnormal rate of FT 4 in the ≥30 years old group was higher than that in the < 30 years old group ( P < 0.05); in second and third trimesters, there were no significant differences between the two age groups ( P > 0.05). Conclusions:Screening for thyroid function in the first trimester of pregnancy is important for women of different ages. Except for women with abnormal thyroid function who have not been treated during the first trimester, the rest may not need to be screened again. Pregnant women aged ≥30 years old may have a higher risk of thyroid dysfunction than those < 30 years old.

To analyze the clinical manifestations and gene mutations in children with congenital insensitivity to pain with anhidrosis (CIPA), and review related literature. An infant diagnosed with congenital insensitivity to pain with anhidrosis was reported. The main clinical manifestations of the infant were painless, no sweat, and repeated fever. Peripheral blood of the infant and his parents was collected, and candidate variants were confirmed by Sanger sequencing. The results of molecular genetic analysis showed that there were compound heterozygous mutations (c.36G>A, c.851-33T>A) of neurotrophic tyrosine kinase receptor type 1 (NTRK1) in the infant. c.36G>A and c.851-33T>A were inherited from his father and mother, respectively. c.851-33T>A is a previously reported mutation, c.36G>A is an unreported mutation, which can lead to the tryptophan changing into a stop codon. According to the American College of Medical Genetics and Genomics (ACMG) variant interpretation guidelines, the mutation is interpreted as pathogenic, and the biological hazard is potentially harmful. Congenital insensitivity to pain with anhidrosis is a rare inherited disorder. Genetic molecular genetic analysis is helpful to diagnose and discover new gene mutations.

Objective To investigate the status of increased blood parathyroid hormone(PTH)level among community residents in Urumqi,and to analyze its correlation with the metabolic parameters including serum Ca and P levels. Methods In May 2013,a cross-sectional survey was conducted,when 1 473 permanent residents in Urumqi, including 844 Han and 629 Uyghurs,were selected by cluster random sampling. PTH and 25-OH vitamin D[25(OH)D] levels were detected by chemiluminescence. Blood Ca, P, Mg, albumin, and creatinine (Cr) were also measured. Based on serum 25(OH)D level,the residents were divided into vitamin D deficiency(<20 ng/ml), vitamin D insufficiency(≥20 and<30 ng/ml),and vitamin D sufficiency(≥30 ng/ml)groups. According to the PTH level,the residents were divided into PTH<65 pg/ml group and PTH≥65 pg/ml group. The metabolic parameters including Ca and P were compared among different ethnic groups. Results In the surveyed population,the rate of increased blood PTH was 12.22%,being higher in females than that in males(13.82% vs 8.45%,P=0.004)and higher in Han Chinese than that in Uyghurs(19.87% vs 6.52%,P<0.01). The proportions of residents with vitamin D sufficiency,insufficiency and deficiency were 3.34%,9.06%,and 87.60% in Uyghurs,and 10.43%,29.98%, and 59.60% in Han,respectively. The rate of 25(OH)D deficiency was significantly higher in Uyghurs than that in Han(P<0.01),especially higher in female Uyghurs(91.43%). In vitamin D deficiency group,the rate of increased serum PTH was significantly increased,higher in Uyghurs than that in Hans(22.14% vs 6.56%,P<0.01),which revealed a negative correlation with 25(OH)D(r=-0.251, P< 0.01). Conclusion 25(OH)D deficiency is prevalent among the community population in Urumqi, with ethnic differences in serum PTH level and the rate of increased blood PTH,which might be associated with vitamin D deficiency.

Objective To construct a ciaR gene-knockout (ΔciaR) mutant of Streptococcus pneu-moniae ( S. pneumoniae) and to investigate the effects of CiaR in CiaH/CiaR, a streptococcal two-component signal-transducing system, on the expression of genes encoding penicillin-binding proteins ( pbps genes) and cia-dependent small RNAs (csRNAs). Methods Electrophoretic mobility shift assay (ESMA) was per-formed to detect the recombinant CiaR (rCiaR)-binding pbps genes. A suicide plasmid pEVP3ciaR for ciaR gene knockout was constructed and then aΔciaR mutant was obtained through homologous recombination and insertion inactivation of the suicide plasmid, and screening with chloromycin. The mutant was identified using PCR and sequencing analysis. E-test was used to detect the minimal inhibitory concentrations ( MIC) of penicillin ( PCN) and cefotaxime ( CTX) against S. pneumoniae strains. Changes and differences in the expression of pbps genes and csRNAs in theΔciaR mutant and its wild-type strain before and after treatment with 1/4 MIC of PCN or CTX were detected using real-time quantitative RT-PCR. Results The rCiaR could bind to the promoter regions in pbp1a, pbp1b and pbp2b genes of S. pneumoniae. The ciaR gene in ΔciaR mutant was inactivated by insertion according to the results of PCR and sequencing analysis. After treatment with 1/4 MIC of PCN or CTX, the expression of pbps genes at mRNA level ( pbps-mRNAs) in theΔciaR mu-tant was significantly increased (P<0. 05), but the levels of csRNAs were significantly decreased (P<0. 05);whereas a significantly decreased pbps-mRNAs (P<0. 05) and increased csRNAs (P<0. 05) were observed in its wild-type strain. The result of E-test showed that the MICs of PCN and CTX against ΔciaR mutant were increased by 250-fold as compared with those against its wild-type strain. Conclusion The CiaR can enhance the drug resistance of S. pneumoniae to PCN and CTX through down-regulating the expres-sion of PBP1a, PBP1b and PBP2b and up-regulating the expression of csRNAs to inhibit the expression of PBPs.
