Objective To investigate the relationship of the changes of bone density and biochemical marker of bone turnover with osteoporosis in the elderly with type 2 diabetes mellitus(T2DM). Methods A total of 102 elderly patients with type 2 diabetes and 42 healthy subjects (normal controls) were included in this study.The bone mineral density (BMD) of lumbar vertebrae and femur were measured by dual-energy X-ray absorptiometry (DXA).The T2 DM subjects were divided into two groups:osteoporosis group (56 cases) and non-osteoporosis group (46 cases).The levels of total procollagen type Ⅰ amino-terminal propeptide (TP Ⅰ NP),β-isomerized carboxyterminal propeptide (β-CTx),parathyroid hormone (PTH),serum calcium (Ca2+),serum phosphorus (P),alkaline phosphatase (ALP),fasting blood glucose(FBG),glycosylated hemoglobin (HbAlc) and body mass index (BMI) were detected. The correlations between BMD of the osteoporosis group and other related factors were analyzed. Results The BMD values of lumbar vertebrae and femur neck,troch,ward's triangle in the osteoporosis group were decreased as compared with control(t=9.006,6.347,7.387,5.321,P＜ 0.01) and the serum TP Ⅰ NP,β-CTx,PTH,ALP,FBG,HbAlc,Creatinine and albumin/Cr in the osteoporosis group were significantly higher than controls(t=2.212,4.431,2.215,3.544,0.433,1.629,0.365,5.436,P＜0.01 or P＜0.05),the 25-(OH)VD3 in the osteoporosis group was lower than in controls(t=2.700,P＜0.01).Correlation analysis showed TP Ⅰ NP was negatively correlated with the BMD of femoral Troch and Ward's triangle (r=-0.413,-0.375,P＜0.01),and β CTx was negatively correlated with the BMD of femoral Troch (r=-0.301,P＜0.05).The TP Ⅰ NP,β-CTx in the overweight group and obesity group were higher than in normal group(F=50.59,51.28; F =96.20,95.71,all P＜0.01);the melbine group had higher TP Ⅰ NP,β-CTx than the thiazolidinedione and sulfonylurea group(F=32.33,33.35,F=31.07,39.18,P＜0.01);the TP Ⅰ NP,β-CTx in the better blood glucose control group were lower than in the bad control group(F=11.32,13.69,P＜0.01);the TP Ⅰ NP,β-CTx in the group with complication were increased as compared with no complication group(F=52.75,70.34,P＜0.01).Conclusions The spine BMD in elderly T2DM patients is decreased to some degree.The combined application of TP Ⅰ NP and β-CTx is helpful for the early diagnosis of osteoporosis in patients with type 2 diabetes.

Objective To observe the difference in treament of thoracolumbar vertebral bodies fractures be- tween AF nail and Dick nail.Methods From March 1998 to March 2007,85 cases of thoracolumbar vertebral bod- ies fractures were followed up.20 cases were fixed with Dick nail,and 65 cases with AF nail.Results The mean,fol- low-up period was 12 months.By comparison of the operating rime,bleeding amount,the recovery rate of vertebral height,the reduction of Cobb angle and capacity of vertebral canal,AF nail was much better than Dick nail.But there was no marked difference in the recover of nerve function.Conclusion AF nail has more power to reduce vertebral height and is easier to set than Dick nail.It will be worthy of more and wider application in basic level hospitals.

Objective To study the macrophage colony-stimulating factor(M-CSF)expression levels of serum and synovial fluids from patients with spondyloarthropathy(SPA)and its contribution to the pathogen- esis of SpA.Methods Eleven SpA synovial tissue samples were compared to those from peripheral blood mononuclear cells(PBMC)of 10 normal subjects using a 1176 gene array.M-CSF was detected in both serum samples and synovial fluids by enzyme linked immunosorbent assay(ELISA).Two groups of AS subjects were tested.The first group consisted of 41 ankylosing spondylitis(AS)patients who had not been treated with bio- logics.The second group consisted of 13 subjects whose serum samples were collected before and 14 weeks af- ter initiation of infliximab.These were compared to serum samples from 28 normal subjects,and synovial fluid samples from 15 SpA patients.Results Expression of M-CSF could be detected in both serum samples and synovial fluids.The concentration of M-CSF in the group of 41 AS patients not treated with biologics correlated with the Bath Ankylosing Spondylitis Disease Activity Index(BASDAI)values(r=0.41,P=0.004).Treatment of infliximab in AS patients led to a significant decrease in the values of BASDAI(P=0.000 07),but no signif- icant change in the serum M-CSF values.Conclusion M-CSF is a promising candidate for research on the mechanisms of SpA and its signaling on pathway in SpA is different from tumor necrosis factor(TNF)-?,and it may provide new basis for developing new anti-biologics for SpA.

Forest musk deer (Moschus berezovskii), a rare wild medicinal animal, is listed under the category of the state key protected wildlife list of China. Musk, secreted by the musk glands, is with high economic and medicinal value and used as precious traditional medicine in China. In order to meet the needs of musk in Chinese traditional medicine, forest musk deer farming was conducted in 1950s, but the research progress on musk secretion mechanism was slow. Therefore, by reviewing the histological and anatomical structure of forest musk deer musk gland, the relationship between sex hormones and the musk secretion process, and the molecular mechanism of the musk secretion, the existing problems in investigating the musk secretion mechanism were analyzed and the development trends in this field were also discussed, in order to provide a reference for further studies on the musk secretion mechanism and improve musk production of forest musk deer.

Objective To evaluate the application of non-bioartificial liver support system (ALSS) combined with liver transplantation(LT) in treating mid-or end-stage chronic severe hepati- tis.Methods ALSS plus liver transplantation were employed in treating 28 patients with mid-or end- stage chronic severe hepatitis.Clinical data from the patients before and after treatment were collect- ed.The survive rate of ALSS plus LT group were compared with that of medication group 99 cases and medication plus ALSS group 30 cases.The data were analyzed with t test and X~2 test.Results After 57 times ALSS treatment,the serum total bilirubin(TBil),prothromin time(PT),bile acid, blood urea nitrogen(BUN),creatnine(Cr) and ammonia of all the 28 patients got improved(P 0.05).The clinical symptoms and signs of the patients were ameliorated at median 3 d(1～153 d). All patients were bridged to liver transplantation successfully after median 20 d(1～153 d).The 3 and 6 months post-operation survival rate of ALSS plus LT group(71.4%,71.4%) were significantly higher than those in medication group(18.2%,11.1%) and medication plus ALSS group(36.7%, 26.6%)(P

Objective To compare the prophylactic efficacy of combination of ganciclovir and acy- clovir or acyclovir alone against cytomegalovirus pneumonia in renal transplant recipients.Methods A to- tal of 217 renal transplant recipient(124 men and 93 women;mean age,32 years;age range,16-72 years) were divided into 3 groups randomly.In 51 cases,acyclovir was taken orally at a dose of 400 mg,3/d,from the third d to 3 months after transplantation.In 74 cases,ganciclovir was administered at a dose of 250 mg/d intravenously from the 21st d to 27th d to replace Acyclovir.In 92 cases,no prophylaxis against eytomegalov- irus pneumonia was performed.All patients were followed 3 months after transplantation.Comparison of the incidence rates of cytomegalovirus pneumonia among the 3 groups was performed using Fisher's exact test. Results Cytomegalovirus pneumonia developed in 20 cases in the 3 groups,including 4 cases(5.4%) in combined use group,2 cases(3.9%)in acyclovir alone group,and 14 cases(15.2%)in control group. Significant difference existed between the 2 experimental and control groups(P＜0.05).However,no signifi- cant difference existed between the 2 experimental groups(P＞0.05).Of the 20 cases,17(85.0%)were cured,and 3 died of respiratory failure.Conclusions Ganciclovir and acyclovir have prophylactic effect a- gainst cytomegalovirus pneumonia in renal transplant recipients.These 2 medications are inexpensive,and the patients have good compliance.
