Objective To investigate the changes of bone mineral density (BMD) in patients with type 2 diabetes (T2DM) complicated with osteoporosis (OP) and analyze the factors related to diabetic osteoporosis (DOP) so as to provide theoretical evidence for early diagnosis and prevention of osteoporosis complicated with T2DM. Methods According to their BMD values, patients were divided into OP group and non-OP group. Then we compared differences in sex, age, body mass index (BMI), diabetes duration, fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), fasting insulin (FIns), insulin sensitivity index (ISI), quantitative of urinary albumin (ALb), quantitative of urinary protein in 24 hours, serum calcium (Ca), phosphorus (P) and alkali phosphatase level (ALP), and made correlation analysis. Results Compared with those in non-OP group, patients in OP group had older age, longer disease course, smaller baric index, lower bone density, higher alkali phosphatase, lower insulin sensitivity index, higher glycosylated hemoglobin, higher quantitative of urinary protein in 24 hours and urinary microprotein, which were significantly different according to t-test (P<0.05). However, the levels of fasting plasma glucose, serum phosphorus and serum calcium did not differ obviously. BMD of type 2 diabetes was negatively correlated to age, disease course, glycosylated hemoglobin, quantitative of urinary protein in 24 hours, ALb and ALP, but positively correlated to BMI and ISI, and had no correlation with serum calcium, serum phosphorus and fasting plasma glucose. Conclusion Many factors, such as older age, low body weight, long duration of the disease, high level of blood sugar, insulin dysfunction, low insulin sensitivity, high serum alkaline phosphatase and diabetic nephropathy, contribute to osteoporosis in T2DM.

Objective To develop a method of loop-mediated isothermal amplification(LAMP) to Staphyloccocus aureus rapidly, specifically, sensitively and simply suited for the primary health agency. Methods According to conserved nucleotide of Staphyloccocus aureus and principle of LAMP, we designed a set of LAMP primers and set up an LAMP reaction system. We evaluated the specificity, sensitivity and re-peatability of the method. In addition,we evaluated the linearity between initial template copies 1g value and reaction time (the time when the fluorescent value is 1×10~4). Results The optimal assay showed that it was no cross-reaction with other closely related members of pathogens, and was 10 times more sensitive than PCR. The coefficient of variance between tests was less than 5% ,and the kinetics curves showed a good line-arity between initial template copies lg value and reaction time(r~2=0. 9501). The detection activity could be finished within 1 h with the sensitivity of LAMP was 100% and the specificity was 94.4%, and the accuracy was 96.6%. Conclusion These findings demonstrated that the LAMP had the potential clinical application for detection and differentiation of Staphyloccocus aureus in the public health agency for its sensitive, specific and simple feature.

OBJECTIVETo test the efficiency of transfecting (99)Tc(m)-labeled anti-miR208b oligonucleotide into early hypertrophic cardiac myocytes in vitro.
METHODSThe anti-oligonucleotide targeting miR208b (AMO) was synthesized and modified with LNA followed by conjugation with N-hydroxysuccinimidyl S-acetyl-meraptoacetyl triglycine (NHS-MAG3) and radiolabeling with (99)Tc(m). NHS-MAG3-LNA-AMO and labeled AMO were purified with Sep-Pak C18 column chromatography, and the former was examined for UV absorption at the 260 nm using Gene Quant DNA/RNA calculator. The labeling efficiency, radiochemical purity, stability and molecular hybridization activity were analyzed. An angiotensin II-induced cell model of hypertrophic cardiac myocytes was transfected with (99)Tc(m)-NHS-MAG3-LNA-AMO via liposome, and the relative expression of miRNA208b and retention ratio of the labeled AMO in early hypertrophic cells were determined.
RESULTSThe labeling efficiency and radiochemical purity of the labeled AMO after purification exceeded 84% and 86%, respectively. The radio- chemical purities of the labeled AMO incubated in serum and normal saline for 12 h were both higher than 80%, and the labeled AMO showed a capacity to hybridize with the target gene. In the hypertrophic model of cardiac myocytes, the retention ratio of labeled AMO at 6 h was higher than 20%.
CONCLUSIONThe (99)Tc(m)-labeled antisense probe can be efficiently transfected into hypertrophic cardiac myocytes in vitro, which provides an experimental basis for subsequent radionuclide imaging studies.

BACKGROUNDThe effectiveness and safety of initiating biphasic insulin aspart 30 in patients who were poorly controlled on oral glucose-lowering drugs were studied in randomized controlled trials, while results from clinical practice remain limited. This subgroup analysis was to provide such findings from a large-scale non-interventional study.
METHODSA1chieve was a multinational, prospective, open-label, non-interventional, 24-week study in patients with type 2 diabetes initiating insulin analogues in 28 countries across Asia, Africa, Europe, and Latin America. After physician had taken the decision to use this insulin, any patient with type 2 diabetes who was not treated with or who had started the study insulin within 4 weeks before inclusion was eligible. Patients were treated with study insulin alone or in combination with oral glucose-lowering drugs. Data on adverse drug reactions, hypoglycemia and glycemic control were collected at baseline, week 12 and 24. This is a report of a Chinese subgroup analysis from the A1chieve study.
RESULTSTotally, 4 100 patients constituted this subgroup. No serious adverse drug reactions were reported. Rates of total, major, nocturnal hypoglycemic events (events/patient per year) were 1.47, 0.10, 0.31 at baseline and 1.35, 0.00, 0.22 at week 24, respectively. Glycemic control was improved as measured by hemoglobin A1c (mean 9.3% to 7.0%, reduction -2.3%), fasting plasma glucose (mean 10.2 to 6.8 mmol/L, reduction -3.5 mmol/L) and postprandial plasma glucose (mean 14.4 to 8.8 mmol/L, reduction -5.6 mmol/L), all P < 0.001. Change in mean body weight was +0.3 kg (P < 0.001).
CONCLUSIONIn this subgroup analysis of the A1chieve study, biphasic insulin aspart 30 improved glycemic control with low risk of hypoglycemia.
