Objective To investigate the characteristics of post-transplantation diabetes mellitus and analyze its risk factors. Methods Extensive survey was carried out to understand the characteristics of post-transplantation diabetes mellitus in patients who received kidney grafting from February 1984 to December 2006. Results Three hundred forty-four post-transplantatian diabetes mellitus patients from 1872 ones after kidney grafting were found from February 1984 to December 2006. The prevalence of new onset post-transplant diabetes mellitus and impaired fasting glucose in kidney allograft recipients were 18. 4% and 12. 7% respectively, being significantly higher than that in general population and other inpatients. The options of immunosuppressants were significantly associated with the prevalence of post-transplantation diabetes mellitus. By multivariate logistic regression analysis, the baseline characteristics of the post transplantation diabetes mellitus patients were significantly associated with increased age(OR: 1. 309, P = 0. 049), elevated level of the triglyceride (OR: 1. 311, P = 0. 005), treatment with taerolimus (FK506) (OR: 1. 522, P = 0. 008), and large dose of intravenous pulsed prednisolane(OR: 1. 239, P = 0. 011), as compared with patients without post-transplantation diabetes mellitus. Besides, the number of patients with at least one acute rejection episode was significantly greater in the post-transplantation diabetic patients. Mycophenolate mofetil (OR: 0. 716, P = 0. 028) and diltiazem (OR: 0. 737, P =0. 015) were associated with lower risk of post-transplantation diabetes mellitus. Conclusions High prevalence of abnormal glucose metabolism in renal allograft recipients during hospitalization was observed. Many risk factors contributed to the development of post transplantation diabetes mellitus.

Effect of interleukin-6 receptor (IL-6R) antibody on polymethyl methacrylate (PMMA) bone cement-mediated expression of osteoprotegerin (OPG) and receptor activator of nuclear factor-kappaB ligand (RANKL) in synovial fibroblasts was investigated. Synovial tissue obtained from total knee arthroplasty was digested and cultured. Inverted microscope was employed to observe the synovial cells and immunocytochemistry (SABC method) staining was used to identify synovial fibroblasts. This experiment was divided into three groups according to different culture media: PMMA group (75 μg/mL PMMA bone cement particles), IL-6R antibody group (10 ng/mL IL-6R antibody+75 μg/mL PMMA bone cement particles), and control group (no IL-6R antibody or PMMA bone cement particles). Influence of IL-6R antibody and PMMA on proliferation of synovial fibroblasts was measured by cell counting kit-8 (CCK-8). ELISA method was used to measure OPG and RANKL levels in culture solution. Fluorescence quantitative real-time PCR (FQ-PCR) was used to detect the expression of OPG and RANKL mRNA. After three consecutive passages, more than 95% of the primary synovial cells became long spindle fibroblast-like cells. SABC staining results showed that the fibroblast-like cells were negative for anti-CD68 antibody and positive for anti-vimentin antibody, with brown madder stained. CCK-8 test demonstrated that the absorbance (A) value at 450 nm was significantly lower in IL-6R antibody group than in PMMA group and control group (P<0.01), but there was no statistically significant difference in A value at 450 nm between the control group and PMMA group (P>0.05). Results of ELISA indicated that the expression of OPG was significantly higher in IL-6R antibody group than in PMMA group and control group (P<0.01). The expression of RANKL was inhibited (P<0.05), and the ratio of OPG/RANKL was significantly increased in IL-6R antibody group as compared with PMMA group and control group. There was no significant difference in the expression of OPG between control group and PMMA group (P>0.05), but the expression of RANKL was higher in PMMA group than in control group (P<0.05), and there was a significant difference in the ratio of OPG/RANKL between them (P<0.05). Results of FQ-PCR revealed the expression of RANKL mRNA was significantly inhibited (P<0.01) and the expression of OPG mRNA was significantly increased (P<0.01) in IL-6R antibody group as compared with PMMA group and control group. The expression of RANKL mRNA was higher in PMMA group than in control group (P<0.05), but the expression of OPG mRNA had no significant difference between them (P>0.05). IL-6R antibody could significantly increase the expression of OPG, but inhibit the expression of RANKL, which might provide a theoretical basis of molecular biology for the prevention and treatment of aseptic loosening of prosthesis.

A cross-sectional survey of 3589 adolescents was conducted in three cities from different typical geographical zones of Guangdong province. The median urinary iodine concentrations (MUI) of adolescents in Nanxiong, Guangzhou and Maoming were 286.6,204.1 and 166.0μ/L, respectively. The MUI of all these adolescents Was 231.7μg/L, which was slightly higher than the current World Health Organization recommendation.

OBJECTIVETo explore the chaotic dynamic process of multiple organs dysfunction syndrome (MODS) and the regulatory effect of Shenqin Liquid (SQL), a Chinese herbal liquid preparation with the action of purging and qi-tonifying.

METHODSEighty SD rats were divided into 4 groups, and were given suspension of zymosan A and paraffine (1 mL/kg) by peritoneal injection except for those in the blank control group to set up the multiple organs dysfunction syndrome (MODS) model. Low and high doses SQL were administered twice at the doses of 30 and 60 g/kg of SQL respectively at an interval of 8 h per day before modeling. Serum concentration of tumor necrosis factor alpha (TNF-alpha) and nitric oxide (NO) in MODS model animals were tested diachronically, eg. 12, 6 h before modeling, during modeling, 6 and 12 h after modeling, and then the mathematic models were built up with compartment analysis. Lyapunov exponents (LE) of the mathematic models were calculated to evaluate their chaotic characteristics of movement and the degree of chaos was ascertained with the correlation dimension (CD).

RESULTSThe serum levels of TNF-alpha and NO were significantly higher than those in the bland control group at modeling, 6, and 12 h after modeling (P <0.01), while those in the low and high doses of SQL were significantly lower than the model group (P <0.01). Moreover, the level of NO in the high dose of SQL was significantly lower than that in the low dose group (P <0. 01). CD of TNF-alpha movement in the blank control group was 0.803 with the LE less than zero; those in the model group was 1. 966 and > 0 respectively; in the low dose and high dose SQL treated groups, CD was 0.517 and 0.653 respectively and LE >0. CD of NO movement in the blank control group was 0.670 and with LE < 0; in the model group, 1.242 with LE > 0; in the low dose SQL group, 0.574 and in the high dose SQL group 0.850, and LE <0 in the two groups.

CONCLUSIONUnder the normal physiologic condition, TNF-alpha and NO moved steadily without chaotic properties; while under the pathologic condition of MODS, they manifest relatively complicated chaotic properties. SQL can intervene the movement of TNF-alpha and NO, decrease the complexity of their chaotic movement, and make them return back to a stable state.

In this work, the titanium powder was used for preparing highly interconnected porous scaffolds by impregnating polymer method. Subsequently, the electrochemical method and the biomimetic mineralization method were adopted to deposit calcium phosphate coatings on the sintered scaffold which was supposed to improve the scaffold bioactivity. The experimental results show, with the use of the two methods, the scaffolds are successfully covered by the deposition of the nano-net structure calcium phosphate coating, and they hold their three dimensional interconnected porous structures. Therefore, this kind of bioactive composite scaffold with such mechanical strength as that of woven bone should be a promising bone graft in clinical applications.

OBJECTIVETo investigate the current state of oral administration of Chinese patent medicine in treatment of chronic kidney disease (CKD) in the Westem medicine hospitals.

METHODSOutpatients of Department of Nephropathy, Peking University Third Hospital with diagnosed CKD confirmed by CKD diagnosis standard were surveyed by questionnaire in May 2009. The following patients' information was collected using the Questionnaire of the Current State of Oral Administration of Chinese Patent Medicine at CKD Clinics. (1) The present symptoms, tongue figure, pulse figure were syndrome typed referring to The Diagnosis, Syndrome Typing, and Efficacy Assessment of Chronic Renal Failure 2006 by Chinese Society of Renal Diseases, Chinese Society of Traditional Chinese Medicine. (2) Names of Chinese patent medicines and Western medicines patients use presently, the dose and dosage, names of hospitals responsible for prescriptions. (3) Patients' basic diseases including diabetes, hypertension, hyperuricemia, and so on at present. Irrational applications of Chinese patent medicines were classified according to the drug instruction and Guiding Principle of Clinical Application of Chinese Patent Medicines (issued by State Administration of Traditional Chinese Medicine). The irrationality was analyzed. Correlated factors such as age, sex, deficiency in origin syndrome, sthenia in superficiality syndrome, the nature and grade of hospitals responsible for prescriptions, total numbers of Chinese patent medicines, and primary diseases, etc. were analyzed using Logistic regression model. These factors might result in irrational application of Chinese patent medicines.

RESULTS102 questionnaires were handed out, with 78 effective ones. Of them, 41 patients (41/78, accounting for 52.6%) were taking Chinese patent medicines. Of the 41 patients, irrational application happened to 24 patients (24/41, accounting for 58.5%), absolute discrepancy of medicines and syndromes to 5 (5/41, accounting for 12.2%), repeated medication to 7 (7/41, accounting for 17.1%), and interaction to 2 (2/41, accounting for 4.9%). Logistic regression model was analyzed. Variables were screened by Enter method. The number of Chinese patent medicines had statistic significance (P<0.05).

CONCLUSIONSThe occurrence rate of irrational application of Chinese patent medicines in CKD outpatients in Westem medicine hospitals was higher. They were mainly manifested as absolute discrepancy of medicines and syndromes and repeated medication. Increased numbers of Chinese patent medicines in recipes would increase the occurrence rate of irrational application of Chinese patent medicines.
