Objective Macrophages are important innate immune cells,and are also the main target cells of Mycobacterium tuberculosis.Macrophages express many kinds of Toll like receptors.TLR2 is a structural component of macrophages in the identification of Mycobacterium tuberculosis.Activation of TLR2 signaling pathway can activate cell signal transduction,induce specific gene expression and secretion of cytokines.Immune function decline in old people and the function of macrophages was also changed.In this article,The role of immunity mediated by TLR2 in macrophages against tuberculosis in the elderly is reviewed.

Objective To investigate the effection of Shenfu Injection (Ginseng-radix aconitum Injection)to the blood coagulation system and its prognosis in the patient of multiple trauma complicated with shock.Methods We prospectively studied 90 patients of multiple trauma complicated with shock,who came from the emergency center of the Second Affiliated Hospital of Medicine' s college of Zhe-Jiang University and emergency department of Lishui People' s Hospital from February 2007 to December 2011,and excluded those suffered with the dysfunction of coagulation system and uncontrolled ongoing bleeding before trauma.And then these eligible patients were randomly divided into two groups:treatment group ( 45 cases ) and control group (45 cases),the control group were received the routine treatment,the treatment group were received Shenfu Injection in early stage based on the routine treatment.The two groups were measured the platelet count (PLT),prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time (TT),fibrinogen (FIB) before treatment and 3,7 days after treatment.Results The differences of the PLT,PT,APTT,TT,FIB between the treatment group and control group at 3,7 d after the treatment was statistically significant (P ＜ 0.05 ). Conclusions Shenfu Injection has positive regulation to the coagulation system in the patient of multiple trauma complicated with shock.

Ten pharmacophore models of beta-tubulin inhibitors were established from the training set of seventeen beta-tubulin inhibitors (two categories) with comformer analysis by using the Catalyst software. The optimal pharmacophore model with two hydrophobic units and two hydrogen bond acceptor units were confirmed (RMS = 0.43, Correl = 0.98, Weight = 2.06, Config = 15.97). This pharmacophore model is able to predict the activity of known beta-tubulin inhibitors and can be further used to identify structurally diverse compounds with higher activity.

Objective To investigate the significance of microsatellite instability(MSI) and expressions of cyclin D1 and P53 in 7,12 dimethylbenz(a)anthracene (DMBA) induced breast carcinoma in rats. Methods Animal model of rat breast carcinoma was duplicated in 30 female Wistar rats by gastric irrigation of DMBA at the dose of 200 mg/kg. Eight microsatellite loci(D1Mitl4, D1Mgh2, D1Mgh6, D3Mit3, D3Mgh9, D5Mitll, D5Mgh5 and D7Mgh1) were selected for the examination of MSI of breast carcinoma by PCR analysis. S P immunohistochemical staining was used to study the expressions of cyclin D1 and P53 in DMBA induced breast carcinoma in rats. Results Of the 27 cases of breast carcinoma, there were 2 cases of MSI at 8 loci, 9 cases with P53 overexpression and 12 cases with cyclin D1 overexpression. All these were associated with histological grading. Conclusion MSI is infrequent in breast carcinogenesis in rats. Cyclin D1 overexpression may be the early event but P53 protein overexpression may be the late event in breast carcinoma.

Objective To study the correlation between the expressions of Bcl-2 and Caspase-3 in intestinal epithe-lial and inflammatory cells of lamina propria and the staging and pathogenesis of ulcerative colitis (UC). Methods The pathomorphological changes of 25 samples of UC in the active phase and remission phase and 25 samples of control were ob-served under microscope. The expressions of Bcl-2 and Caspase-3 were detected by immunohistochemistry SP method. The correlations between expressions of Bcl-2, Caspase-3 and UC staging were analyzed. Results There were no significant dif-ferences in expressions of Bcl-2 and Caspase-3 in intestinal epithelial cells between three groups (P>0.05). The expression of Bcl-2 in inflammatory cells of lamina propria was significantly higher in active UC group than that of normal control group (P＜0.05), no significant difference between UC remission group and normal control group (P>0.05). There was a higher positive expression of Caspase-3 in inflammatory cells of lamina propria in UC remission group. There was correlation be-tween Bcl-2, Caspase-3 and UC staging (r=0.371 and 0.4453 respectively). Conclusion The expression levels of Bcl-2 and Caspase-3 were related with pathogenesis of UC. The detection of expression levels of Bcl-2 and Caspase-3 has a cer-tain application value in UC staging.

Objective To study the correlation between TCM differentiation of syndromes typing for ulcerative colitis (UC) and expressions of Bax and Caspase-3.Methods 50 patients with UC were divided into 2 groups according to TCM syndrome differentiation including dampness-heat internal accumulation syndrome group (25cases),deficiency of spleen and stomach syndrome group (25cases).Immunohistochemistry was used to study expression of Bax and Caspase-3 in colonic mucosas and compare with the normal group (25cases).Results The expressions of Bax were highest in dampness-heat internal accumulation syndrome group (4.56±1.58).The expressions of Bax of deficiency of spleen and stomach syndrome group were lower than dampness-heat internal accumulation syndrome group(3.28± 1.14)scores.There were significant differences between the three groups (P＜0.05).However,There were no significant difference between dampness-heat internal accumulation syndrome group and deficiency of spleen and stomach syndrome group in terms of the Caspase-3expressions (P＞0.05).In addition,Caspase-3 and Bax were positively related in each group(r=0.23and 0.21).Conclusion The high expressions of Bax,Caspase-3 in ulcerative colitis were closely related to TCM typing according to syndrome differentiation.Caspase-3 and Bax were adjustment in apoptosis.The detection of expression of Bax,Caspase-3 is helpful to the TCM syndrome differentiation and to the selection of treatment plan.At the same time,it can provide more important experiment basses for the pathogenesis of ulcerative colitis.

A method was developed to assay α-Hydroxyltriazolam and α-Hydroxyalprazolam,　which are the major metabolites of triazolam and alprazolam respectively,in human urine.　After addition of 2-hydroxyflurazepam　(interal standard) and hydrolysis with β-glucuronidase, the hydroxy-metabolites were extracted with hexane-dichloromethane (1∶1) at pH　10.8, then were derivated with (BSTFA). The analysis was performed on a HP-5 capillary column with electron-capture detector.The detection limits of analysis in urine were about 1μg/L.The method was successfully applied to urine specimens collected from healthy human volunteers who ingested 0.5 mg of triazolam or 0.8 mg alprazolam. The method was enough sensitive to assay urine specimen excreted at 24 h by volunteers after taking the medicine.

BACKGROUND:Bone cement has certain toxic effects on the human body. The probability of renovation is high after bone cement total hip arthroplasty. It is reported that the long-term effect of cementless total hip arthroplasty is apparently better than bone cement total hip arthroplasty, and can be renovated conveniently. OBJECTIVE:To investigate the clinical effect of cementless total hip arthroplasty on hip joint disease, and to compare the difference between unilateral replacement and bilateral replacement. METHODS: Clinical and folow-up data of 233 patients (280 hips), who were treated with cementless total hip arthroplasty in the Department of Orthopedics, Wuzhou Worker’s Hospital, Seventh Affiliated Hospital of Guangxi Medical University from July 2007 to December 2013, were retrospectively analyzed. According to the replacement program, they were divided into unilateral replacement group (n=186) and bilateral replacement group (n=47). Harris score of hip joint, visual analog scale score of thigh pain, the excelent and good rate of hip joint during final folow-up and complications were compared between the two groups before replacement, at 6, 12 and 24 months after replacement. RESULTS AND CONCLUSION:No significant difference in Harris scores was detected before replacement, at 6, 12 and 24 months after replacement (P > 0.05). Harris score was significantly higher at 6, 12 and 24 months after replacement compared with that before replacement in both groups (P < 0.05). No significant difference in the excelent and good rate was detected in the unilateral replacement group (87%) and the bilateral replacement group (86%) (P > 0.05). No significant difference in the visual analog scale score was seen before replacement, at 6, 12 and 24 months after replacement (P > 0.05). Visual analog scale scores were significantly lower at 6, 12 and 24 months after replacement than that before replacement in the two groups (P < 0.05). There was no significant difference in the incidence of complications after replacement in patients of both groups (P > 0.05). These findings confirm that the effects of cementless total hip arthroplasty for hip joint disease are evident, can effectively restore hip joint function. No significant difference was detected between unilateral replacement and bilateral replacement. Strict replacement operation and matching of prosthesis and medulary cavity can effectively reduce thigh pain after replacement.

Objective To investigate the effects of Dihuangyinzi(DHYZ) on behaviors and RAGE/p38 pathway in APP/PS1 mice.MethodTwenty APP/PS1 dementia mice were randomly divided into model group(n=10) and Chinese medicine group(n=10).The blank group was C57 BL/6 J normal mouse(n=10).The mice in Chinese medicine group were intragastric administration with DHYZ (9.75 g·kg-1·d-1).The mice in model group and blank group were treated with distilled water.After 30 days,the abilities of learning and memory of mice were detected by Morris water maze.The expression of amyloid-beta1-42(Aβ1-42) in the hippocampus and cortex was detected by immunohistochemistry.Reactive oxygen species of brain tissue were detected by DCFH-DA Methods in the brain of APP/PS1 mice.Gene expression level of receptor for advanced glycation end products(RAGE) was measured by real-time polymerase chain reaction (RT-PCR) in the cortex and hippocampus of APP/PS1 mice.The expression of phospho-mitogen-activated protein kinases (p38) was analyzed with Western blot and immunofluorescence analysis in the cortex and hippocampus of APP/PS1 mice.Results Behavioral Results showed that DHYZ significantly increased the distance((23.088±7.083)cm) and residence time((1.961±1.230)s)of effective area in Morris water maze on the fifth day(P<0.05,P<0.01)and remarkably increased the number of effective area crossings((1.607±0.405) times) and plats((0.893±0.283) times) in Morris water maze on the fifth day(P<0.01,P<0.05).DHYZ also significantly reduced the intracelluar ROS level(122.611±7.630) in the brain(P<0.01),and DHYZ could depress the expression of RAGE(1.467±0.081,7.983±0.136) and phosphorylation of p38 (0.376±0.026,0.538±0.016)in the cortex and hippocampus of APP/PS1 mice(P<0.01,P<0.05).Conclusions The Results demonstrate that DHYZ can partly improve memory impairment of APP/PS1 mice by the inhibition of RAGE/p38 pathway.
