Objective To study the variation characteristics of peripheral blood β-catenin and DKK1 levels in patients with rheumatoid arthritis (RA) and the correlation with bone and joint damage.Methods One hundred and eight patients with RA (observation group) and 110 healthy individuals (control group) were selected.The bone mineral density(B MD) in the femur (femur neck,Ward area,greater trochanter,total femur area) and lumbar spine (L2,3,4) were measured by dual-energy X-ray absorptiometry instrument.X-ray for two hands were evaluated according to the Sharp score.The peripheral blood β-catenin and DKK1 levels were detected by enzyme-linked immunosorbent assay (ELISA).Multiple analysis was completed by multiple linear regression and Logistic regression.Results The peripheral blood DKK1 level in observation group was significantly higher than that in control group [(8.2 ±5.0) mg/L vs.(6.1 ±4.2)mg/L],there was statistical difference (t =2.452,P =0.025),but there was no statistical difference in β-catenin level between the 2 groups (t =15.947,P =0.142).Compared to control group,patients with RA had lower BMD at femur and lumbar spine (P ＜ 0.01).The incidence of osteoporosis in observation group was significantly higher than that in control group [31.5％ (34/108) vs.15.5％ (17/110)],there was statistical difference (x2 =9.289,P =0.005).The correlation analysis results showed that the peripheral blood DKK1 was positive correlation with erythrocyte sedimentation rate (ESR),28-jonit disease activity score (DAS28),alkaline phosphatase (AKP) and two hands X-ray joint narrowing space score in patient with RA (P ＜ 0.01 or ＜ 0.05) ;the peripheral blood β-catenin level was positively correlated with ESR and AKP (P ＜ 0.01 or ＜ 0.05).The multiple linear regression results showed that the disease duration,health assessment questionnaires (HAQ),DKK1 influenced two hands X-ray joint narrowing space score; but the age,disease duration,HAQ influenced two hands X-ray bony erosion score.The multiple Logistic regression results showed that the two hands X-ray Sharp score was the risk factor of osteoporosis at femur in patients with RA; but the age was the risk factor of osteoporosis at lumbar in patients with RA.Conclusions Peripheral blood DKK1 level in patients with RA increases significantly,while there is no apparent alteration in β-catenin level.Peripheral blood DKK1 level is correlated with disease activity and joint space narrow score.

Objective The aim of this study was to determine whether psychomotor performance and visual reaction time were affected by acute exposure to mild or moderate hypoxia. Method Eighteen healthy male volunteers performed finger tapping, simple reaction time(SRT) and 4-choice reaction time(CRT) tests at simulated altitude of 300 m (control),2800 m, 3600 m and 4400 m for 1 h in a hypobaric chamber. Result SaO2 decreased from 98%(control) to 90%,82% and 74% respectively at the various altitudes. All the performance parameters showed no significant change after exposure to 2800 m for 1 h relative to ground level(P>0.05). However the mean reaction time of 4-CRT under 3600 m prolonged and performance decreased as compared with baseline value(P<0.05), and the performance decreased further under 4400 m(P<0.01). No significant difference was found in finger tapping and SRT even under exposure to 4400 m for 1 h.Furthermore, no decrease in correct rate were observed at any altitude (P>0.05). Conclusion The results from this study demonstrated that there were no measurable impairment of visual reaction time and psychomotor performance under exposure to an altitude of 2800 m for 1 h. However, adverse effects on psychomotor performance were observed under 3600 m and over.

Objective To explore the effects of acute mild and moderate hypoxia on human mood state.Method The mood states of 18 healthy male volunteers were evaluated by self-assessment questionnaires,profile of mood state (POMS) and state anxiety inventory (S-AI) after random exposure to simulated altitude of 300 m (control),2800m,3600 m and 4400 m for 1 h in a hypobaric chamber.Result The data at 300 m level were taken as the baseline control.The negative mood state factor points (tension,fatigue etc.) increased gradually as the altitude level increased while V (vigor-activity) points had a tendency to decrease (P<0.05 or P<0.01).No significant difference was found in the points of (D,A) even under exposure to 4400 m(P>0.05).At the early period of 2800 m exposure the tension points of POMS and S-AI scores were higher than those of control level (P<0.05) then dropped to baseline level when exposure to this altitude for 1 h.Conclusion Exposure to acute mild hypobaric hypoxia at 2800 m for 1 h has adverse effect on mood state of healthy person and the negative effect was further aggravated with the increment of altitude level.

OBJECTIVE: To investigate the clinical outcomes of artificial bone (hydroxyapatite) and bone cement implantation in treating young patients with avascular necrosis of the femoral head caused by different reasons. METHODS: A total of 18 patients (23 hips) with Ficat stage Ⅲ and Ⅱ avascular necrosis of the femoral head were treated with dead bone debridement, artificial bone and cement implantation in Department of Orthopedics, Third Affiliated Hospital of Guangxi Traditional Chinese Medical College from October 2003 to July 2008. The patients were followed up for 24.6 months (ranging 3 months to 5 years). The affected hip function was evaluated by modified Merled'Aubigne Scores and X-ray. RESULTS: Mean hip scores improved significantly from 11.65 to 15.09 after surgery. Postoperative radiographs demonstrated the improved collapse and restoration of femoral head sphericity. The femoral heads of most patients remained the appearance after surgery, and the necrosis range did not enlarge. The patients were satisfactory to the treatment results. CONCLUSION: Artificial bone and cement implantation could restore head sphericity and prevent further collapse. The method can be used as an alternative for treatment of avascular necrosis of femoral head at Ficat stage Ⅱ and Ⅲ, especially for young patients.

Toimprovethesensitivity,aCuOnanoparticledopedinmolecularlyimprintedpolymer(MIP)film for the determination of phenobarbital was prepared by using methacrylic acid as functional monomers, ethylene glycol maleic rosinate acrylate as a cross linking agent by thermal polymerization method. The electrochemical properties of the nano-doped sensor were investigated using cyclic voltammetry ( CV ) , differential pulse voltammetry ( DPV ) , electrochemical impedance spectroscopy ( EIS ) and chrono-amperometry ( CA) . The chemical structures and morphologies of the imprinted films were characterized using Fourier transform infrared spectroscopy and scanning electron microscopy. The results indicated that the sensors response value of peak current showed a linear dependence on the phenobarbital concentration in the ranges of 1. 2 × 10-7-1. 5 × 10-4 mol/L of phenobarbital. ( Linear regression coefficient=0. 9984 ) with the detection limit ( S/N=3 ) of 8. 2 × 10-9 mmol/L. The prepared sensor was successfully applied to the determination of phenobarbital in practical samples with recovery ranging from 96 . 5% to 103 . 0%.

Objective To analyze the relationship between renal pathological characteristics and clinical prognosis in type 2 diabetic kidney disease patients,and discuss predictive value of pathological type and indexes for renal function declining rate and related outcome events.Methods Ninety-two type 2 diabetes patients from PUMC Hospital (with macroalbuminuria and followed up no less than 6 months,excluding patients with non-diabetic renal disease) were divided into typical diabetic glomerulopathy group (DG,n=51) and atypical diabetes-related renal disease group(ADRD,n=41) according to renal pathological findings.A retrospective cohort study was performed to investigate renal pathological features and prognosis.Results Total of 29 renal outcome events and 12 death events occurred in DG group and none in ADRD group; the survival rate and kidney survival rate are different between two groups (P ＜ 0.05); DG group,thick GBM,severe vascular and tubular lesion are predicative indicators for renal outcome event; mesangial volume fraction is predicative indicator for renal outcome events independent of age and serum creatinine.Conclusions DG and ADRD patients have different prognosis and might undergo different pathophysiological mechanisms; renal pathological type and mesangial volume fraction could help predicting outcomes of type 2 diabetic nephropathy patients.

Objective To explore whether hypoxia could promote epithelial-mesenchymal transition (EMT) in various differentiated colorectal cancer cells, and analyse the effect of hypoxia on invasion and migration of colorectal cancer cells. Methods HCT116 (poorly differentiated) and HT-29 (highly differentiated) colorectal adenocarcinoma cells were selected respectively. The morphological changes of two cell lines were observed after 0,10,25,50,100 and 150 mg/L cobalt chloride (CoCl2) treatment for 48 h. The expression of hypoxia-inducible factor-1α(HIF-1α) protein was analysed after 0, 10,25,50,100 and 150 mg/L CoCl2 treatment for 48 h. An optimal concentration of CoCl2 was then selected. Methylthiazolyl tetrazolium (MTT) assay was used to detect the proliferation of two kinds of colorectal cancer cells induced by CoCl 2 at different time points (0, 24, 48, 72 and 96 h), and to select an optimal time. Under the optimal concentration and time conditions, the HCT116 and HT-29 cells were processed by hypoxia (hypoxia group) and normoxia (normoxic group). Transwell invasion assay and Wound healing assay were used to detect cell invasion and migration in two groups. Western blot assay and RT-PCR were used to detect protein and mRNA expression levels of HIF-1α, E-cadherin and Vimentin in two groups. Results Two kinds of cells showed obvious morphological changes after 50 mg/L CoCl2 treatment for 48 h. HIF-1αprotein level first increased and then decreased in two groups of cells with the increased concentration of CoCl 2, and 50 mg/L CoCl2 was the optimal concentration (P<0.05). The cell proliferation showed a tendency to decrease after the increase in both kinds of cells with or without hypoxia for 0-96 h (P<0.05), and 48 h was the optimal time. The transmembrane number and cell migration rate were significantly more in hypoxia group than those of normoxic group (P<0.05). The protein and mRNA levels of HIF-1α and Vimentin were significantly higher in hypoxia group than those of normoxic group in HCT116 and HT-29 cell lines (P<0.05). E-cadherin protein and mRNA levels were significantly lower in hypoxia group than those of normoxic group (P<0.05). Conclusion Hypoxia can promote EMT in different differentiated colorectal cancer cells, and can enhance invasion and migration of two kinds of colorectal cancer cells.

Both phytase and endoglucanase are additives in feed for mono-gastric animal known for their effects. Recombinant vector pPICZalpha-EG was constructed and transformed to GS115-phyA, a Pichia pastoris strain that had integrated with phytase gene, generating GS115-phyA-EG. Both phytase and endoglucanase activities in the supernatant were determined after methanol induction of GS115-phyA-EG. Phytase and endoglucanase activity reached 39.4% and 56.2% activity compared to GS115-phyA and GS115-EG, respectively. Properties of the mixed enzyme suggest that the optimal temperature and pH value be 55 degrees C and 5.5 respectively. Both phytase and endoglucanase showed greater than 80% activity across temperature ranges 45 degrees C to 55 degrees C and pH ranges 4.5 to 5.5. Expressing more than one enzyme in one system could save time and money during induced expression, and the mixed enzyme might apply for treating forge before feeding with poultry.
