This in vitro study demonstrated that taurine supplemented culture medium enhanced alkaline phosphatase (ALP) activity, osteocalcin secretion and mineralized matrix formation. Taurine induced activation of ERKI/2 and osteoblast differentiation, which was blocked by pretreatment of osteoblasts with ERKI/2 inhibitor (PD98059), suggesting taurine stimulated osteoblast differentiation via ERKI/2.

Objective To explore the association of HbA1C with microvascular complications,and to evaluate the diagnostic value of HbA1C in diabetes mellitus in high-risk populations of Guangzhou.Methods HbA1C,blood glucose,fundus photography,and microalbuminuria were detected in 208 permanent residents with high-risk factors of diabetes.The receiver operating characteristiC(ROC)curves were used to estimate the area of HbA1C,fasting plasma glucose(FPG),postprandial 2 h plasma glucose(2hPG)under the curve for discriminating microvascular complications.Results There were 14.9% adults suffering from diabetic retinopathy and 12% microalbuminuria in high risk populations of diabetes.The optimal cutoff points of HbA1C,FPG,and 2hPG in detecting retinopathy were 5.8%,7.0 mmol/L,and 10.9 mmol/L respectively.The thresholds for increasing prevalence of microalbuminuria were5.8% for HbA1C,6.4 mmol/L for FPG,and 10.7 mmol/L for 2hPG.Conclusions The prevalence of diabetic microvascular complications increases dramatically at the concentration of HbA1C 5.8%.As a diagnostic value for microvascular complications,there is no significant difference between HbA1C and 2hPG.

OBJECTIVE: To investigate the effect of acute cardiac injury on the activation of interleukin-1 beta (IL-1 beta) signaling in the spinal cord. METHODS: Acute cardiac injury rat model was established by intra-myocardial injection of formalin through diaphragm. IL-1 beta expression was determined by Western blot, immunohistochemistry and in situ hybridization. The DNA binding activities of 2 IL-1 beta transcription factors, activator protein (AP)-1 and nuclear factor kB (NF-kappaB) were measured by electrophoretic mobility shift assay (EMSA). RESULTS: After cardiac injury, the IL-1 beta protein level was dramatically upregulated in the spinal cord. The upregulated IL-1 beta was mainly expressed in the neurons in the lamina II approximately IV of the spinal cord. In response to cardiac injury, the DNA binding activities of NF-kappaB and AP-1 were greatly activated. CONCLUSION Acute cardiac injury could activate the spinal IL-1 beta signaling, which, in turn, may be involved in the progression of heart failure after injury.

Objective To explore the relationship between different types of female reproductive system dysplasia and age of visit, clinical manifestations, common types of combined malformations and endometriosis. Methods The patient′s medical records in the Second Hospital of Hebei Medical University from December 2002 to June 2016 were collected and retrospectively analyzed. Results Among 924 cases of genital tract dysplasia, uterine dysplasia (65.3%, 824/1 261) was the most common, followed by vaginal dysplasia (28.3%, 357/1 261), hymen atresia and urogenital fistula (3.7%, 47/1 261), and cervical dysplasia (2.6%, 33/1 261). (1) The youngest age was in patients with hymen atresia and urogenital fistula, with a median of 14.5 years old, while the older age were in patients with uterine, vaginal and cervical dysplasia, with median age of 25.0, 24.0 and 23.0 years old, respectively. (2) The clinical manifestations were lack of specificity, mainly abnormal findings of physical examination or accessory examination, primary amenorrhea, lower abdominal pain, infertility, adverse pregnancy history. (3) About other systemic malformations, urological malformations were the most common (4.8%, 44/924), followed by spinal malformations (0.5%, 5/924), inguinal hernia (0.4%, 4/924), heart malformations (0.2%, 2/924), cleft lip and palate (0.2%, 2/924). Oblique vaginal septal syndrome and MRKH syndrome were the most likely to be associated with other system malformations. (4) About combination with endometriosis, there was no significant difference between obstructive genital tract malformations (2.3%, 9/385) and non obstructive genital tract malformations (1.7%, 9/539; P=0.469). Conclusions Female reproductive system dysplasia is the most common in uterine dysplasia, followed by vaginal dysplasia, hymen atresia and urogenital fistula, and cervical dysplasia. The age of visit is generally older, often found by abnormal findings of physical examination or accessory examination, primary amenorrhea, lower abdominal pain, infertility, adverse pregnancy history;and could be combined with a variety of other system malformations, most seen by urinary system malformations,there is also the risk of endometriosis.
