OBJECTIVECentral obesity is considered to be a central component of metabolic syndrome. Waist circumference (WC) has been widely used as a simple indicator of central obesity. This study is aimed to evaluate the sensitivity of WC cut-off values for predicting metabolic risk factors in middle-aged Chinese.

METHODSThe study involved 923 subjects aged 40-65 years. The metabolic risk factors were defined according to the Chinese Joint Committee for Developing Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults. WC cut-off 85-90 cm and ⋝90 cm were used as cut-off values of central pre-obesity and central obesity in males, respectively, while WC 80-85 cm and ⋝85 cm were used as cut-off values of central pre-obesity and central obesity in females.

RESULTSFirst, WC values corresponding to body mass index (BMI) 24 kg/m2 and visceral fat area (VFA) 80 cm2 were 88.55 cm and 88.51 cm in males, and 81.46 cm and 82.51 cm in females respectively. Second, receiver operating characteristic curves showed that the optimal WC cut-off of value was 88.75 cm in males, higher than that in females (81.75 cm). Third, the subjects with higher WC values were more likely to have accumulating metabolic risk factors. The prevalence of metabolic risk factors increased linearly and significantly in relation to WC levels.

CONCLUSIONWC cut-off values of central pre-/central obesity are optimal to predict multiple metabolic risk factors.

A strain KX6,producing thermotolerant endoglucanase,was isolated from compost. The morpholo-gical identification and 16S rRNA sequence analysis showed it belongs to Streptomyces xylophagus. The production and characterization of endoglucanase from Streptomyces xylophagus KX6 was studied. Maximum endoglucanase yield of 0.538 IU/ml was achieved with medium pH8.0,containing CMC2Na 1.0% as carbon resource,soybean meal 1% as nitrogen resource,2% inoculating volume,30% 250 ml triangle flask bulk for medium volume at 40℃ 200r/min shaker for 48h. The endoglucanase exhibited optimum catalytic activity at pH7.0 and 50℃. The enzyme was stable at 50℃,and able to retain 60% of the full activity,when it was incubated at 60℃ for 1h.The enzyme was stable at pH6.0~7.0. All these findings suggest that the enzyme is a thermotolerant neutral endoglucanase.

The morphological index of the seedlings including the plants height, the ground diameter, the leaf amounts, the fresh weight of the whole plant and the ratio of height to diameter was measured and the principal components were analyzed so as to determine the grading index, and stepwise cluster analysis was applied for clustering analysis. Pot experiments were used to measure the indicators of plant growth and development, the yield and the quality. The results showed that the height and ground diameter were determined as the quality indicators of the seedlings grading and the standard quality grading of seedlings of Anoectochilus roxburghii was initially set up, different seeding plants influenced the plants growth and the yield. The ground diameter of the class I was larger than that of the class II and III, so as the yield. The seedling grading had no obvious effect on the internal quality of medicinal materials. The results of the study provide the basis for standard cultivation of A. roxburghii.

Objective To carry out mutation analysis of deafness-associated genes for deaf newborns and their parents, and to estimate the recurrence risk for their parents to have deaf descendants.Methods Suspected cases of inherited deafness were identified by neonatal hearing screening and questionnaires. Genomic DNAs of suspected cases and their parents were extracted from their peripheral blood samples . Common deafness-associated genes(i.e. GJB2,SLC26A4 and 12S rRNA genes)were amplified by polymerase chain reaction(PCR),and those PCR products were sequenced for the mutation analysis.Results From 2013 to 2016, 193 cases of deafness were found in neonatal hearing screening,29 cases of suspected as hereditary deafness were screened,and 17 out of 29 cases were found to have mutations in deafness-associated genes(detection rate:58.62%). GJB2 homozygous mutations were identified in two cases and their parents,and the recurrence risk to have deaf descendants was 100%. Four cases of suspected hereditary deafness had GJB2 homozygous mutations,and their parents were both GJB2 mutation carriers. There was one case with SLC26A4 homozygous mutations,and their parents were both SLC26A4 mutation carrier. Two cases were detected to have GJB2 V371 homozygous mutations,and their parents were both GJB2 V371 mutation carriers. For those seven parents carrying deafness-associated mutations above,the recurrence risk of deafness for their descendants was 25%.Conclusion In addition to hearing screening,the genetic diagnosis of deafness-associated genes is helpful to clarify the cause of suspected neonatal hereditary deafness,and can provide objective reproductive counseling and guidance for those deaf parents or parents with deaf children.

Background: The detection of glutamic acid decarboxylase 65 (GAD65) autoantibodies is essential for the prediction and diagnosis of latent autoimmune diabetes in adults (LADA). The aim of the current study was to compare a newly developed electrochemiluminescence (ECL)-GAD65 antibody assay with the established radiobinding assay, and to explore whether the new assay could be used to define LADA more precisely. Methods: Serum samples were harvested from 141 patients with LADA, 95 with type 1 diabetes mellitus, and 99 with type 2 diabetes mellitus, and tested for GAD65 autoantibodies using both the radiobinding assay and ECL assay. A glutamic acid decarboxylase antibodies (GADA) competition assay was also performed to assess antibody affinity. Furthermore, the clinical features of these patients were compared. Results: Eighty-eight out of 141 serum samples (62.4%) from LADA patients were GAD65 antibody-positive by ECL assay. Compared with ECL-GAD65 antibody-negative patients, ECL-GAD65 antibody-positive patients were leaner (P<0.0001), had poorer β-cell function (P<0.05), and were more likely to have other diabetes-associated autoantibodies. The β-cell function of ECLGAD65 antibody-positive patients was similar to that of type 1 diabetes mellitus patients, whereas ECL-GAD65 antibody-negative patients were more similar to type 2 diabetes mellitus patients. Conclusion Patients with ECL-GAD65 antibody-negative share a similar phenotype with type 2 diabetes mellitus patients, whereas patients with ECL-GAD65 antibody-positive resemble those with type 1 diabetes mellitus. Thus, the detection of GADA using ECL may help to identify the subtype of LADA.

OBJECTIVETo observe the effect of Chuanhuang No.1 Recipe (CHR) on renal function and micro-inflammation in phase 3 chronic kidney disease (CKD) patients.

METHODSTotally 60 phase 3 CKD patients were randomly assigned to the treatment group (treated by CHR) and the control group (treated by Losartan Potassium), 30 in each group. All patients received basic treatment. Patients in the treatment group took CHR decoction, 400 mL each time, one dose per day, while those in the control group took Losartan Potassium, 50-100 mg per day. All medication lasted for 24 weeks. Changes of serum creatinine (SCr), blood urea nitrogen (BUN), estimated glomerular filtration rate (eGFR), serum uric acid (UA), 24 h urinary protein excretion (24 h U-pro), urinary microalbumin (U-Alb), high-sensitivity C-reactive protein (hs-CRP), serum tumor necrosis factor (TNF)-alpha, and serum IL-6 were detected and compared before and after treatment. Efficacy was also compared.

RESULTSCompared with before treatment, SCr and BUN significantly decreased in the treatment group (P<0.05, P<0.01); eGFR in- creased (P<0.05). Only UA obviously decreased in the control group (P<0.05), but with no obvious change in SCr, BUN, or eGFR. Compared with before treatment, 24 h U-pro decreased after treatment in the treatment group (P<0.05), but with less decreased level when compared with the control group. U- Alb was also significantly decreased in the control group (P<0.01). There was statistical difference in 24 h U-pro and U-Alb between the two groups after treatment (P<0.05). Compared with before treatment, hs-CRP obviously decreased after treatment in the two groups, but serum levels of TNF-alpha and IL-6 obviously decreased only in the treatment group (P<0.05). The total effective rate was obviously higher in the treatment group than in the control group (70.00% vs. 43.33%, P<0.01).

CONCLUSIONCHR could efficiently improve the renal function of phase 3 CKD patients and alleviate the micro-inflammation.
