Objective:To evaluate the impact of sample pooling strategy on 2019-nCoV RNA detection results.Methods:Ten negative swabs were stored in 6 ml virus transport medium, mixed thoroughly and diluted 1∶2 and 1∶10. Inactivated 2019-nCoV culture medium was added to simulate pooling samples: 10 pooling samples, 5 pooling samples and 1 swab sample. Extraction and amplification were made using three nucleic acid extraction reagents a, b, and c with different extraction methods and systems, as well as five 2019-nCoV detection reagents A-E with various template loading volumes and sensitivities respectively.Results:For the same sample, the Ct values of extracted templates a were 2.10±0.47 and 3.46±0.62 earlier than extracted templates b and c. For samples with identical amplifying, the Ct valves of N and ORF1ab gene of A reagent were 1.16±0.48 and 2.36±0.54 earlier than that of reagent B. Adding nucleic acid of 10 negative swabs to the amplification system lagged the Ct values of reagent A by about 1.36±0.32 Ct, while Ct values of reagent B were not affected. Extracted by regent a, a lag of 1.66±0.39 Ct on average was observed in C, D, and E reagents in detecting pooling samples of ten swabs as compared with one swab sample. When extracting 400 copies/ml pooling samples of ten swabs by reagent a, N gene could be detected by reagents C and E, but not by reagent D.Conclusion:Large amount of extraneous DNA is introduced by sample pooling, which could interfere the effiency of extraction and amplification. Strategies of using extraction reagents with large loading volume and high effiency, together with amplification reagents with large template volume and low limit of detection are helpful for ensuring detection sensitivity of pooling samples, and greatly reducing the risk of false negative results.

Objective:To investigate the value of renal glucose threshold and related factors in patients with type 2 diabetes mellitus.Methods:According to the cut-off point of normal renal glucose threshold(RT G 8.9-10 mmol/L), 107 patients with type 2 diabetes mellitus hospitalized in the Endocrinology Department of our hospital were divided into three groups: high RT G group(RT G>10 mmol/L), medium RT G group(8.9 mmol/L≤RT G≤10 mmol/L), and low RT G group(RT G<8.9 mmol/L). The clinical data and biochemical characteristics of each group were collected and analyzed. Results:The proportions of patients with high, medium, and low RT G of type 2 diabetes mellitus were 56%, 29%, and 15%, respectively. There were significant differences in RT G value, age, course of disease, body mass index(BMI), fasting plasma glucose(FPG), HbA 1C, total cholesterol(TC), serum creatinine, mean blood glucose(MBG), and 24-hour urine glucose between high and medium RT G groups. RT G, gender, BMI, FPG, HbA 1C, TC, and MBG in patients with high RT G group were different from those in low RT G group. Only RT G revealed a difference between medium and low RT G groups. Correlation analysis showed that RT G was positively correlated with gender, age, BMI, HbA 1C, TC, and low density lipoprotein-cholesterol(LDL-C). Regression analysis showed that BMI, HbA 1C, and LDL-C were the related factors affecting the RT G of patients with type 2 diabetes. Conclusion:There is a larger proportion of patients with high RT G in type 2 diabetes mellitus. Their BMI, HbA 1C, and LDL-C are associated with RT G in the patients with type 2 diabetes mellitus.

Objective:To explore the association of bone resorption marker β carboxyterminal peptide of collagen Ⅰ (β-CTX) with hypercalcemia in patients with Graves′ disease (GD).Methods:287 patients with GD who were hospitalized in the endocrinology department of Fuyang People′s Hospital from January 2021 to December 2021 were divided into control group ( n=251) and hypercalcemia group ( n=36) according to the corrected blood calcium level. The clinical data and serum β-CTX level of the two groups were compared. Logistic regression model was used to analyze the risk factors of hypercalcemia in GD patients. Pearson correlation was used to analyze the correlation between serum β-CTX level and other indexes. Results:Of the 287 GD patients, 36 were diagnosed as hypercalcemia, and the incidence of hypercalcemia was 12.54%. The levels of free triiodothyronine (FT3), free thyroxine (FT4), blood phosphorus (P) and β-CTX in hypercalcemia group were higher than those in control group, and the total parathyroid hormone (iPTH) in hypercalcemia group were lower than those in control group (all P<0.05). Multivariate Logistic regression analysis showed that FT3 ( OR=1.283, 95% CI: 1.049-1.570, P<0.05), iPTH ( OR=0.924, 95% CI: 0.863-0.989, P<0.05), β-CTX ( OR=2.488, 95% CI: 1.193-5.189, P<0.05) were the influencing factors for hypercalcemia in GD patients. Pearson correlation analysis showed that β-CTX was positively correlated with FT3, FT4, blood calcium, P, alkaline phosphatase (ALP), total procollagen type I amino end terminal peptide (PINP), N-bone-gamma-carboxyglutamic-acid-containing proteins (N-MID) and 25(OH)D, and negatively correlated with iPTH (all P<0.05). Conclusions:β-CTX is highly expressed in the serum of GD patients with hypercalcemia, which is a risk factor for the occurrence of hypercalcemia in GD patients.

Chronic non-communicable disease is a major public health problem affecting the health of residents in china. Evidence shows that, in addition to four major risk factors, i.e. unreasonable dietary, lack of physical activity, smoking and drinking, epidemic and severe outcome of chronic disease is associated with many infectious diseases. Increasingly cancers have been shown to have an infectious etiology. There is also a significantly increased risk of infectious disease such as influenza, pneumonia and other infectious disease in people with pre-existing chronic non-communicable diseases like diabetes, heart disease, and lung diseases. And more than that, there is a high risk of susceptibility to death and severe outcomes among them. Epidemiological studies has confirmed, that through targeted vaccine inoculation, liver cancer, cervical cancer can be effectively prevented, while influenza or pneumonia vaccine are related to reduced risk of hospitalization or death and hospitalization expenses regarding with a variety of chronic diseases. World Health Organization and several other professional organizations have put forward recommendations on vaccine inoculation of chronic disease patients. Programs targeting infectious factors are also an important aspect of chronic diseases prevention and control, therefore, related researches need to be strengthened in the future.
