Objective To investigate the role of dynophin and substance P in pruritus with 5/6 subtotal nephrectomy rats (STNx). Methods 5/6 subtotal nephrectomy rots were prepared. After 24 weeks , STNx rats entered in end stage renal disease(ESRD). Sixty male SD rats were divided into 4 groups, STNx+P group(n=15), STNx+dynophin group( n=15), STNx control group(n=15) and sham operation group(n=15). Substance P (SP), dynophin and saline were intradermal injected separately. After injection, scratch reaction of rats in 30 minutes were recorded. And then SP concentration in blood was estimated by ELISA and SP expression in skin was examined by immunohistochemisty. Results SP concentration in blood of STNx rats were (1010.2±103.5)pg/ml, which increased to (2530.0± 236.3) pg/ml in STNx+SP group and decreased to (612.4±72.2)pg/ml in STNx+dynophin group, and it was the lowest in sham opera- tion group (240.2±36.5)pg/ml. SP expression in skin was similar to that of in blood. The scratch times in STNx+SP group were highest (7.3±1.9 times), there was no significant difference between STNx + dynophin group and STNx control group. Conclusion Pruritus in ESRD rats was correlated to the increase of SP in blood and skin. Intradermal injection of dynophin can decrease SP in blood and skin, but can not induce scratch in STNx rats.

Sweetpotato starch thermal properties and its noodle quality were analyzed using a rapid predictive method based on near-infrared spectroscopy (NIRS). This method was established based on a total of 93 sweetpotato genotypes with diverse genetic background. Starch samples were scanned by NIRS and analyzed for quality properties by reference methods. Results of statistical modelling indicated that NIRS was reasonably accurate in predicting gelatinization onset temperature (T(o)) (standard error of prediction SEP=2.014 degrees C, coefficient of determination RSQ=0.85), gelatinization peak temperature (T(p)) (SEP=1.371 degrees C, RSQ=0.89), gelatinization temperature range (T(r)) (SEP=2.234 degrees C, RSQ=0.86), and cooling resistance (CR) (SEP=0.528, RSQ=0.89). Gelatinization completion temperature (T(c)), enthalpy of gelatinization (DeltaH), cooling loss (CL) and swelling degree (SWD), were modelled less well with RSQ between 0.63 and 0.84. The present results suggested that the NIRS based method was sufficiently accurate and practical for routine analysis of sweetpotato starch and its noodle quality.

OBJECTIVETo evaluate the value of echocardiography in the diagnosis of noncompaction of the ventricular myocardium (NCVM) and to elucidate the echocardiographic characteristics of NCVM.

METHODSThis study included 53 patients (28 boys and 25 girls), with an age for initial diagnosis of 15 days to 18 years, who were diagnosed with NCVM by echocardiography between May 2006 and May 2015. Transthoracic two-dimensional echocardiography and color Doppler were performed for qualitative diagnosis, and the end-diastolic non-compacted layer/compacted layer (N/C) ratio measured in the parasternal ventricular short-axis sectional view was selected as the criterion for quantitative diagnosis.

RESULTSThe excessively prominent ventricular trabeculae and deep inter-trabecular recesses were all seen in 53 cases, and the blood flow in the cardiac chambers was connected to the inter-trabecular recesses. The areas involved in NCVM were mainly the apex (100%) and the middle segment of the left ventricular lateral wall (98%), followed by the middle segment of the left ventricular posterior wall (49%) and the middle segment of the left ventricular inferior wall (42%). In 53 children with NCVM, the N/C ratio was 4.3±1.9 (2.1-10.0). Cardiac insufficiency was found in 83% (44/53) of the children with NCVM, and the left ventricular ejection fraction for these children was (43±9)%.

CONCLUSIONSEchocardiography can be used in the qualitative and quantitative diagnosis of NCVM and in the evaluation of cardiac function. The apex and the middle segment of the left ventricular lateral wall are often involved in NCVM, accompanied by decrease in the left ventricular ejection fraction.

Six heavy metals, including As, Cu, Hg, Cd, Pb and Cr in Panax notoginseng were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES) combined with wet digestion method. The samples of P. notoginseng were collected in 12 different regions, including Yunnan and Guangxi Province. Green Standards of Foreign Trading Medicinal Plants & Preparations was used as the standard to evaluate the pollution status of As, Cu, Hg, Cd, Pb and Cr in P. notoginseng. The results showed that content of As and Cd exceeded the limit of the standard and the percentage was 32.4% and 29.7%, respectively, while Cu, Hg and Pb were all bellow the limit. The SPSS 16.0 software was used to analyze the data. The occurrence of contained heavy metals has been discussed.

OBJECTIVETo compare the impact of various types of neck dissection on postoperative shoulder function.

METHODSThe shoulder functions of 66 patients with oral squamous cell carcinoma (OSCC) and cN0 necks who underwent various types of neck dissection were evaluated by Constant's shoulder function test and neck dissection impairment index at least 12 months after surgery.

RESULTSThe patients with accessory spinal nerve reserved had better shoulder function than those with accessory spinal nerve resected. In the group with accessory spinal nerve reserved, the patients receiving selective neck dissection (SND) showed better shoulder function than those with modified radical neck dissection (MRND). The shoulder dysfunction and pain arising from SND were minor in patients with selective neck dissection.

CONCLUSIONSThe shoulder function after SND was superior to those after RND and MRND.

In order to evaluate the effect and mechanism of the mulberry leaf alkaloid, flavones, and polysaccharide intervention on diabetes, the overall metabolite profiling characteristics for the plasma of diabetic mouse was performed by using an ultra-performance liquid chromatography/electrospray-tandem mass spectrometry (UPLC-ESI-MS). The 8 potential biomarkers were found in diabetic mice plasma based on the data of MS/MS characteristics obtained from the UPLC-OrbitrapMS analysis, which mainly involved in sphingolipids, amino acid metabolic pathway. The principal component analysis showed that the normal group and model group were obviously distinguished and implied that metabolic disturbance was happened in diabetic mice plasma. The extracts of mulberry leaf flavonoids, polysaccharide, alkaloid had exhibited the effects of callback function for diabetic mice through regulating the amino acid metabolism and sphingolipid metabolism.

This study was aimed to evaluate whether mesenchymal stem cells (MSCs) obtained from patients with myelodysplastic syndrome possess immunosuppressive effect. MSCs from bone marrow samples of MDS patients were isolated, cultured and expanded. MSCs were morphologically analyzed and their immunophenotype were determined by flow cytometry. Various amounts of MSCs were added into one-way mixed lymphocyte reaction. MSCs from MDS patients were tested for their ability to suppress in vitro proliferation of autologous and allogeneic peripheral blood lymphocytes (PBLs). The results showed that 3 x 10(3 - 1) x 10(5) MSCs from MDS patients could inhibit autologuous PBLs proliferation to (66.9 +/- 20.1)% - (30.2 +/- 5.9)% of maximal response, as well as inhibit allogeneic PBLs proliferation to (56.6 +/- 14.7)% - (20.5% +/- 9.7)% of maximal response, as compared with inhibitory ability of MSCs from healthy donors, there was no significant difference (P>0.05). It is concluded MSCs from patients with myelodysplastic syndrome also possess immunosuppressive activity.

This study was purpose to examine the effect of dimethyl sulfoxide (DMSO) and Tween 80 on the growth and viability of stromal cells (BMSC), colony-forming units for granulocytes and macrophages (CFU-GM) and bone marrow endothelial cell line (BMEC) from murine bone marrow in vitro, and to analyze the concentration-effect relationship. The colony yields of colony-forming units fibroblastic (CFU-F) and CFU-GM were assessed in the murine bone marrow cell cultures at various concentrations of DMSO or Tween 80 and in the control groups. The MTT assay and trypan blue exclusion were used to determine the cell viability and percentage of survival in BMSC and BMEC cultures with or without either of these organic solvents. The results showed that the colony yields of both CFU-F and CFU-GM were decreased significantly (p<0.05 or <0.01) at the concentrations (v/v final) of 2% DMSO or 0.005%-0.01% Tween 80 respectively, as compared with control. The cell viability and percentage of survival of BMSC and BMEC cultures were significantly reduced (p<0.05 or <0.01) at 0.5%-1.0% DMSO or 0.002%-0.005% Tween 80, as compared with control. With the increase of volume fractions of these solvents, the decreased percentages of corresponding measurements were increased by degrees. It is concluded that when the concentration of DMSO or Tween 80 goes to a certain level in cell culture medium, either of the organic solvents has an inhibitory action or/and cytotoxicity on the growth and viability of BMSCs, CFU-GM and BMECs. The growth inhibition and cytotoxic response are more significant at higher concentrations of these solvents.
