Objective To ascertain the pressure ulcer prevalence among secondary and tertiary general hospitals in different areas of Guangdong Province, and describe pressure ulcer related nursing measures in hospitalized patients. Methods A cross-sectional descriptive design was used in the present study. 5 secondary and tertiary general hospitals including 25164 hospitalized patients from different regions in Guangdong Province were recruited. There were 267 pressure ulcer patients among them. Minimum Data Set (MDS) was used to measure prevention measures of hospitalized patients. Pressure ulcer patients′questionnaire was used to measure medical treatment of pressure ulcer patients. Results The overall prevalence rates of pressure ulcers in the 25 hospitals range from 0 to 3.49%, with an average of 1.26%. The prevalence rate in the secondary general hospitals was 1.8%(41/2266), which was significant higher than that of in the tertiary general hospitals(1.0%, 226/22998), χ2=13.48, P<0.01. For the hospitalized patients at risk, 42.0%(1408/3353) of patients didn′t use any systemic support surface, 45.8%(1537/3353) of patients didn′t use any local support surface. In the pressure ulcer patients, 35.2%(94/267) of patients didn′t use any systemic support surface, 14.2% (38/267)of patients didn′t use any local support surface, and 61.4%(164/267) of pressure ulcer patients didn′t use any skin care products. Conclusion The prevention measures of pressure ulcer in Guangdong province were not effective, further improvements are still required.

Objective To evaluate the impact of autoantibodies to angiotensin Ⅱ type 1 receptor AT1-AA on clinic outcomes of delayed graft function (DGF) grafts.Method We reviewed the records of all 139 consecutive adult recipients who received single kidney transplantation and clinical management between Jan.2010 and Dec.2012 in our centre.The serum levels of AT1-AA were measured by a streptavidin-enzyme-linked immunosorbent assay.All patients with DGF were enrolled in this study and divided into two groups:(1) AT+ DGF group (serum AT1-AA positive,11 cases) ;(2) AT-DGF group (serum AT1-AA negative,23 cases).All clinical and laboratory data were recorded in our transplant database system at each visit.Result 139 recipients were enrolled.The overall presence of DGF was 24.5％ (34/139).The incidence of DGF in patients with high binding AT1-AA was significantly higher than that in those with low binding of AT1-AA (11/24 vs.23/115,45.8％ vs.20.0％,P＜0.05).In addition,longer duration of renal replacement therapy (59 ± 32 vs.47 ± 26 months,P＜0.05),higher resistance index (0.80 ± 0.10 vs.0.72 ± 0.10,P＜0.05) of allografts and more severe acute tubular injury (2.7 ± 0.5 vs.1.8 ± 1.1,P＜0.05)/acute tubular necrosis (0.9 ± 0.5 vs.0.5 ± 0.3,P＜0.05) were observed in AT + DGF group than in AT-DGF group.One-year graft survival and death censored graft survival were similar between two groups (90.9％ vs.95.7％,P＞0.05).Conclusion Presence of high binding anti-AT1 receptor had detrimental impacts on initiation and development of DGF.

OBJECTIVETo explore the correlationship between platelet count and efficacy of traditional Chinese medicine (TCM) or Western medicine (WM) in treating rheumatoid arthritis (RA) patients.

METHODSA total of 356 patients with confirmed diagnosis of active RA from 9 clinical centers were randomly assigned to the TCM group (184 cases) and the WM group (172 cases). The TCM group was treated with basic therapy (administration of glucosidorum tripterygll totorum and Yishen Juanbi Pill) and TCM syndrome differentiation dependent treatment, while the WM group was treated with non-steroidal anti-inflammatory drugs and slow-acting anti-rheumatic drugs. The therapeutic efficacy was assessed with ACR20, the joint damage degree of both hands was evaluated by X-ray.

RESULTSThe platelet count was positively correlated to the X- ray grading of joint damage, namely, patients with a more severe joint damage often presented a higher platelet count. After treatment, in patients with joint damage of X-ray grade II or III and effectively treated with TCM, also in patients with joint damage of grade III and effectively treated with WM, the platelet count was lower than that in those treated ineffectively.

CONCLUSIONPlatelet count is closely correlated to the efficacy of drug therapy, therefore, it may be taken as an important index for judging the curative effect of therapeutic approach in treating RA patients.

OBJECTIVETo explore the correlations between diagnostic information and therapeutic efficacy in rheumatoid arthritis (RA) with decision tree model analysis.

METHODSThree hundred and ninety seven patients came from 9 clinical centers were randomly divided into the Western medicine (WM) group (n=194) treated with non-steroidal anti-inflammatory drugs and slow-acting antirheumatic drug and the Chinese medicine (CM) group (n=203) with basic therapy and syndrome-differentiation dependant TCM treatment. TCM and WM diagnostic information were collected. The ACR 20 was used for efficacy evaluation and the information of patients before treatment was analyzed by SAS 8.2 statistical package. Through single-factor exploratory analysis, odds ratio of efficacy and variable was calculated taken P < 0.2 as the including criteria for data mining analysis with decision tree model. All data were classified into the training set (75%) and verifying set (25%) with efficacy as the variable for layering to make further verification of the data-mining analysis.

RESULTSTwenty variables were included in the CM group and 26 in the WM group in the data-mining model. In the former, 9 variables were positively correlated to the efficacy, including degree of arthralgia, tenderness and morning stiffness, number of swollen joint, and joint with tenderness, levels of IgM, rheumatoid factor (RF), C-reactive protein (CRP), and total assessment from doctor; and disease duration and degree of nocturnal polyuria were negatively correlated to that. While in the latter, 8 were positively correlated to the efficacy, including erythrocyte sedimentation rate (ESR), sour and weak waist and knees, white fur in tongue, joint ache and stiffness, swollen joint, and total assessment from doctor and patient, and red tongue with yellow fur and leucocyte count negatively correlated to it. Data mining with decision tree analysis revealed that different combinations of morning stiffness, slight red tongue, joint tenderness and nocturnal polyuria in the CM group, and those of white fur in tongue, CRP level, leucocyte count and morning stiffness in the WM group showed different efficacy, which were also verified in the randomly chosen verifying set.

CONCLUSIONTo analyze the correlations between diagnostic information and therapeutic efficacy with decision tree analysis is conformed to the theory of TCM in applying treatment according to syndrome differentiation individually, thus it would contribute to elevate the accuracy of therapy.

Objective To investigate the role of transcriptional-coactivator with PDZ-binding motif( TAZ) in genistein-induced osteoblastogenic differentiation of mouse bone marrow-derived mesenchymal stem cells ( BMSCs) .Methods Mouse BMSCs were cultured in phenol red-freeα-MEM containing osteogenic supplements for inducing osteogenic differentiation.BMSCs were transfected with siRNA-TAZ and treated with genistein.The temporal sequence of osteoblastic differentiation in BMSCs cultures was assayed by measuring alkaline phosphatase activity (ALP) and calcium deposition.The mRNA expression of bone sialoprotein ( BSP) and osteocalcin ( OC) were detected by reverse transcription-polymerase chain reaction(RT-PCR).The binding interaction between TAZ and cbfa1 was identified by co-immunoprecipitation.Results TAZ expression was detected during the induction of osteogenic differentiation, the ALP activity and calcium deposition were significantly decreased in BMSCs which were transfected with siRNA-TAZ.Genistein(0.01-1 μmol/L) exhibited a dose-dependent effect on TAZ expression in mouse BMSCs cultures.Treatment with genistein ( 1 μmol/L ) resulted in increased ALP avtivity and calcium deposition of BMSC cultures as function of time.Genistein(1μmol/L) also promoted the nuclear localization of TAZ and augmented the interaction between TAZ and cbfa1, and by which upregulated cbfa1-mediated gene expression such as BSP and OC.However, the ALP avtivity and calcium deposition, as well as the expression of BSP and OC were not promoted by genistein in BMSCs transfected with siRNA-TAZ.Conclusion These data suggest that the TAZ plays an important role in genistein-induced osteoblastic differentiation of mouse BMSCs cultures.

OBJECTIVETo perform a meta-analysis on clinical outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults.

METHODSPubmed database (from 1968 to March 2014), Cochrane library and CNKI database (from 1998 to March 2014) were searched. Case-control study on minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults were chosen,and postoperative infection, operative time, blood loss, fracture nonunion rate, delayed union,fracture malunion rate were seen as evaluation index for meta analysis. The system review was performed using the method recommended by the Cochrane Collaboration.

RESULTSTotally 5 studies (366 patients) were enrolled. Meta-analysis showed that there were significant meaning in postoperative infection between MIPPO and ORIF [OR = 0.23,95% CI (0.06,0.92), P = 0.04]; fracture nonunion rate in MIPPO was lower than in ORIF group [OR = 0.16, 95% CI (0.03,0.76), P = 0.02]; operative time in MIPPO was shorter than in ORIF group, and had significant difference [MD = -14.42, 95% CI (-27.79, -1.05), P < 0.05]; blood loss in MIPPO was less than in ORIF group [MD= -87.17,95%CI (-99.20, -75.15), P < 0.05]; there was no obviously meaning in delayed union between two groups.

CONCLUSIONFor distal tibial fractures in adults, MIPPO has, advantages of short operative time, less blood loss, lower incidence of infection and fracture non-uniom, but with high fracture malunion rate. MIPPO for distal tibial fractures in adults is better than ORIF, and the best treatment should choose according to patient's condition.

Objective: To observe the effect of electroacupuncture (EA) pretreatment on the protein expression of c-fos in fastigial nucleus (FN) and lateral hypothalamus area (LHA) in rats with acute myocardial ischemia-reperfusion injury (MIRI), and to explore the role and mechanism of FN and LHA in EA at the Heart Meridian fighting against acute MIRI reaction. Methods: Seventy Sprague-Dawley rats were randomly divided into a sham operation group, a model group, an EA-Heart Meridian group and an EA-Lung Meridian group, with 14 rats in each group; an LHA lesion plus EA-Heart Meridian group (LHA+EA-Heart Meridian group) and a FN lesion plus EA-Heart Meridian group (FN+EA-Heart Meridian group), with 7 rats in each group. Except the sham operation group, the left anterior descending branch of coronary artery was ligated to establish acute MIRI rat models in the other 5 groups. In the three groups with EA-Heart Meridian treatment, Shenmen (HT 7) and Tongli (HT 5) were selected; Taiyuan (LU 9) and Lieque (LU 7) were selected in the EA-Lung Meridian group. All the EA groups received EA stimulation prior to modeling, with 1 mA in current intensity and 2 Hz in frequency, 20 min each time, once a day for a total of 7 d. The sham operation group and the model group did not receive EA stimulation. The electrocardiogram was observed in the rats to analyze the ST-segment deviation and cardiac arrhythmia score. The expression of c-fos protein in FN and LHA was detected by immunohistochemistry method. Results: Compared with the sham operation group, the ST-segment deviation, cardiac arrhythmia score and the expression of c-fos protein in the FN and LHA increased significantly in the model group (all P<0.05). Compared with the model group, the ST-segment deviation, cardiac arrhythmia score and the expression of c-fos protein in FN and LHA decreased significantly in the EA-Heart Meridian group (all P<0.05). Compared with the EA-Heart Meridian group, the ST-segment deviation and cardiac arrhythmia score increased significantly in the EA-Lung Meridian group, LHA+EA-Heart Meridian group and FN+EA-Heart Meridian group (all P<0.05); the expression of c-fos in FN increased significantly in the EA-Lung Meridian group and LHA+EA-Heart Meridian group (both P<0.05); the expression of c-fos in LHA increased significantly in the EA-Lung Meridian group and FN+EA-Heart Meridian group (both P<0.05). Conclusion: FN and LHA are involved in the mechanism of EA at Heart Meridian to improve the acute MIRI reactions, and the cerebellum may participate in the improvement of cardiac function by EA through the cerebellum-hypothalamus projection.

The mammalian cell nucleus is highly structured and organized into various membrane-less nuclear compartments called nuclear bodies. Nuclear bodies are highly dynamic structures, with a variety of substances gathered inside to promote the more efficient conduct of certain biological reactions. It dynamically produces responses under different biological processes and stress conditions such as tumorigenesis, apoptosis, antiviral defense, and plays an important role in regulating cell homeostasis. Tumor is a major public health problem, and finding new targets is the key to tumor therapy. How the nuclear bodies are involved in the development of tumor has not been reported. This review aims to provide a new understanding of how the nuclear bodies regulates tumor progression and provide a new effective strategy for tumor prevention and treatment.

Based on the transcriptome database of Salvia miltiorrhiza, specific primers were designed to clone a full-length cDNA of ent-kaurene oxidase synthase (SmKOL) using the RACE strategy. ORF Finder was used to find the open reading frame of SmKOL cDNA, and ClustalW has been performed to analysis the multiple amino acid sequence alignment. Phylogenetic tree has been constructed using MEGA 5.1. The transcription level of SmKOL from the hairy roots induced by elicitor methyl jasmonate (MeJA) was qualifiedby real-time quantitative PCR. The full length of SmKOL cDNA was of 1 884 bp nucleotides encoding 519 amino acids. The molecular weight of the SmKOL protein was about 58.88 kDa with isoelectric point (pI) of 7.62. Results of real-time quantitative PCR analyses indicated that the level of SmKOL mRNA expression in hairy roots was increased by elicitor oMeJA, and reached maximum in 36 h. The full-length cDNA of SmKOL was cloned from S. miltiorrhiza hairy root, which provides a target gene for further studies of its function, gibberellin biosynthesis and regulation of secondary metabolites.
