Objective To compare zinc-finger BED domain-containing 3 ( ZBED3 ) expression in various tissues of C57BL/6J mice and the effects of liraglutide, glucose, and insulin on the levels of ZBED3 protein expression in C57BL/6J mice and db/db mice. Methods The mRNA level of ZBED3 in various tissues of C57BL/6J mice was measured by realtime PCR. The protein level of ZBED3 was measured by using western blot. Results ZBED3 mRNA levels were detected in muscle, spleen, kidney, brain, heart, lung, and liver of C57BL/6J mice, yielding the highest expression in muscle. Additionally, The liver ZBED3 levels were higher in db/db mice compared with C57BL/6J mice (P<0. 01). Furthermore, the protein expression of ZBED3 was significantly increased in liver tissues of db/db mice treated with high concentrations of liraglutide, glucose or insulin(P<0. 05), however, the expression of ZBED3 only responded to high concentration of glucose in liver tissues of C57BL/6J mice. Conclusion ZBED3 may act as a novel factor in regulating glucose metabolism. The expression of ZBED3 can be regulated by liraglutide, glucose, and insulin. Thus, ZBED3 may play an important role in conditioning of hyperglycemia.

ObjectiveTo investigate the effect of rhPTH (1-34) and elcatonin on bone metabolism and serum secreted protein acidic and rich in cysteine ( SPARC ) in postmenopausal women with osteoporosis.Methods One hundred and twenty-four postmenopausal women with osteoporosis were randomly divided into 2 groups:One group was treated with recombinant human parathyroid hormone ( 1-34 ) [ rhPTH ( 1-34 ) ] 200 U/d by subcutaneous injection (PTH group,n =89 )and another group was treated with elcatonin 20 U/week by intramuscular injection (CT group,n =35 ) for 12 months.All patients received a basic therapy with oral calcium ( Ca 600 mg+ Vit D3125 U,q..d.).The bone mineral density ( BMD ) of lumbar spine( L2-4 ),the left femoral neck,greater trochanter,and Ward's triangle,serum calcium and phosphate were measured by baseline,6 months' and 12 months.Levels of serum bone-specific alkaline phosphatase( BSAP),serum secreted protein acidic and rich in cysteine (SPARC)were determined by an ELISA assay.ResultsBy 12 months,rhPTH ( 1-34 ) treatment significantly increased the lumbar spine L2-4 BMD 7.9％ (P＜0.05),serum calcium 8.3 ％ ( P＜ 0.05 ),serum BSAP 93.4％ ( P＜ 0.05 ),serum SPARC by 12.6％[ ( 195.68±59.57 vs 173.81 ±81.33 ) pμg/L,P＜0.05 ].Elcatonin therapy increased the lumbar spine L2-4 BMD by 3.2％ (P＜0.05) at the end of 12 months,but elcatonin did not influence serum calcium,BSAP and SPARC.The rhPTH( 1-34 ) increased lumbar spine L2-4 BMD more than elcatonin did at 12 months( P＜0.05 ).ConclusionrhPTH (1-34) could promote the bone anabolism more effectively than elcatonin did.Serum SPARC may play an important role in promoting osteogenesis by rhPTH.

Objective To evaluate the effect of electrical stimulation of the pelvic floor muscles combined with bladder training on urinary dysfunctionafter incomplete spinal cord injury.Methods Sixty-two incomplete spinal cord injury patients who had received an operation between November 2009 and December 2014 were enrolled and divided randomly into a control group (n=32) and a treatment group (n =30).Both groups were treated with conventional intermittent catheterization,while the treatment group was additionally given electrical stimulation of the pelvic floor muscles combined with bladder training.The residual urine volume was recorded before and after the treatment.Uurodynamic examinations were conducted,and the rate of successful catheter extraction and of urinary tract infection on the 15th and 30th day of treatment,were recorded and analyzed.Results All of the patients were followed-up for an average of 18.5 months.Significant improvement was observed in the residual urine volume,the maximum or average urinary flow rate,and the detrusor pressure at peak flow of both groups.However,at the end of follow-up the treatment group recorded significantly better results on all these measures than the control group.The successful catheter extraction rate of the treatment group (96.7％) was significantly higher than that of the control group and their average number of catheterization days was significantly fewer.The urinary tract infection rates on the 15th and 30th day of treatment were 16.7％ and 6.7％ in the treatment group,significantly lower than in the control group.Conclusions Electrical stimulation of the pelvic floor combined with bladder training significantly improves urination function after an operation for incomplete spinal cord injury,decreases the days of catheterization and lowers the rate of urinary tract infection.Such combined therapy is worth promoting in clinical practice.

Objective To investigate urine adiponectin changes and related factors in different stage of type-2 diabetic ne-phropathy.Methods A total of 1 1 9 DN patients admitted to the Yongchuan Hospital of Chongqing Medical University in 2013 were selected.The general indices and laboratory examination results were retrospectively analyzed.1 1 9 type-2 diabetic nephropathy patients were divided into normal Proteinuria group,micro-Proteinuria group,macro-Proteinuria group,according to urine albumin excretion rate in 24 hours.45 health subjects from Physical examination center were enrolled as normal group.The UAER of the three groups were compared and the correlation between each index and UAER was analyzed.Results Urine adiponectin levels in normal Proteinuria group was significantly lower than micro-Proteinuria group(P <0.01)and macro-Proteinuria group(P <0.01). Urine adiponectin levels in micro-Proteinuria group was significantly lower than macro-Proteinuria group (P <0.01)and higher than normal group(P < 0.01 ).Urine adiponectin levels in macro-Proteinuria group were significantly higher than normal group (P <0.01 ).Multiple linear regression analysis showed that HDL-C,FPG,HbA1c and UAER had effects on the levels of Urine adiponec-tin.Conclusion Urinary adiponectin levels are associated with type 2 diabetic nephropathy,and which was related with HDL-C, FPG,HbA1c and UAER.

Objective To investigate the incidence and etiological factors of hyponatremia following traumatic brain injury (TBI) and analyze the relationship between hyponatremia and the patient’s age, gender, type of injury, Glasgow coma scale (GCS), operation and computerized tomography (CT) scan of head. Methods Clinical data of 136 pa-tients with moderate or severe TBI in our hospital were analyzed retrospectively, including patient’s age, gender, type of injury, GCS, operation, brain edema and basal skull fracture. The relationship between clinical data and hyponatremia were analyzed statistically by Chi-square test and multivariate Logistic regression analysis. Results There were 56 pa-tients with hyponatremia in 136 patients (81 males) with moderate or severe TBI. Multivariate Logistic regression analysis showed that hyponatremia secondary to TBI was not associated with patient’s age, gender, type of injury and operation or not. However, there was a high correlation between hyponatremia following TBI and clinical characteristics of TBI at ear-ly stage, such as GCS, brain edema and basal skull fracture. Conclusions Patients with TBI is more likely to develop hy-ponatremia when they have the following clinical factors, such as GCS≤8, brain edema or basal skull fracture. Preven-tive measures should be given to these patients in advance.
