Objective To develop a limb support suitable for timely treatment of a large number of patients in wartime or public emergencies.Methods There were two kinds of limb supports including a ground-based rollator and a table-mounted limb bracket,which were both composed of three components for bracing,supporting and regulating.The bracing component was responsible for load bearing,the supporting one contacted the limb,and the remained one was to regulate the support.The limb support could be driven electrically,pneumatically or manually.Results The limb support had its height,angle and width regulated easily to avail itself to the patients,and had no need for extra assistance.Conclusion The limb support gains advantages in practicability,safety,comfort and portability,and thus is worthy promoting in levels of medical facilities especially the first-line medical units in emergency conditions.

Objective: To investigate the changes of adhesion molecules in peripheral blood in patients with recurrent cerebral infarction. Methods: By cytometry and enzyme-linked immunosorbent assay, the expression of integrin Mac-1 ?-sub-unit(CD18) ,intercellular adhesion molecule-3(CD50) intercellular adhesion molecule-1 (CD54) ,very late antigen-4 ?-subunit and p-subunit(CD49d and CD29),CD44 and L-selectin(CD62L) in lymphocyte,the expression of platelet membrane glycopro-tein I b- I a complex a-subunit (CD41), P-selectin (CI)62p) ,the serum level of soluble P-selectin(sP-selectin) and soluble intercellular adhesion molecule-1 (sICAM-1) were measured in 33 recurrent cerebral infarction patients and 44 patients with previous ever-single cerebral infarction history. Results: Compared with previous ever-single cerebral infarction history patients, the positive percentage of CD18,CD50,CD54 ,CD49d,CD29,CD44 and CD62L in lymphocytes ,CD41 on platelet did not significantly change,while the positive percentage of CD62p on platelet and the level sP-selectin,sICAM-1 were significantly higher (P

Objective To explore the possibility of basic fibroblast growth factor(bFGF)and epidermal growth factor(EGF)combined with striatal conditioned medium promoting the directional differentiation of rat bone marrow mesenchymal stem cells(BMMSCs)into dopaminergie neurons.Methods 1.Separation and culture of BMMSCs:BMMSCs were harvested from healthy adult Wistar rats for serial subcultivation.2.Preparation of Striatal conditioned medium:newborn Wistar rats within 24 hours were selected,and their brain tissues were removed to prepare striatal conditioned medium.3.Induced differentiation of BMMSCs:the 5th passage BMMSCs were collected and pre-induced in low glucose-Dulbecco's modified eagle medium(L-DMEM)containing bFGF and EGF.Twenty-four hours later,pre-induction liquor was replaced with striatal conditioned medium for further induced differentiation.4.Result assessment:the morphological changes of stem cells were observed under inverted phase microscope.The expression of neuron specific enolage(NSE)and tyrosine hydmxylage(TH)were identified by immunocytochemical technique.Results The cell body of rat BMMSCs contracted into round and spindle shape after induction by bFGF and EGF combined with striatal conditioned medium.Partial neuron-like cells with prominence could be found.Immunocytochemieal detection showed that the percentages of NSE and TH positive cells were(72.70±14.81)% and(34.50±15.93)%,respectively.Conclusion BMMSCs can be induced directionally into dopaminergiC neurons by bFGF and EGF combined with striatal conditioned medium in vitro.

Objective To investigate the renal function changes of the children with breast milk jaundice(BMJ) and effect of early interference treatment on renal function. Methods Serum bilirubin and urine - minim protein (?2-MG,?1-MG, Alb and IgG) of the 50 patients with BMJ were measured when they were in hospital within 12 hours and the last day separately , at the same time, 20 healthy newborns had been chosen to serve as control group. Results Compared with control group, the urine minim protein of treatment group increased with the rise of serum bilirubin. When serum bilirubin was 205.2 - 256.5 ?mol/L, urine ?2- MG had mild increasing (P

Objective To detect the argyrophilic proteins in nucleolar organizer regions(Ag-NORs) that express rDNA and rRNA proliferation of T lymphocytes before chemotherapy and after complete remission(CR) in children with primary acute leukemia(AL).Methods The argyrophilic granules area of NOR/nuclear area(I.S%) of T lymphocytes was detected by image analysis system in peripheral blood of 42 patients before chemotherapy and after CR and 30 normal children.Results I.S% in the patients before chemotherapy(5.06%?1.36%) were significantly lower than those in the healthy donors(7.51%?1.06%)(t=8.238 P0.05).Conclusion These results suggest that decrease of Ag-NORs expresses the evidence for tumour induced suppression of immune function of T cells in children with AL prior to treatment.

This study is to establish the fingerprint for Phyllanthus emblica and their tannin parts from different habitats by HPLC for its quality control. The determination was carried out on a Diamonsil C18 (4.6 mm x 250 mm, 5 microm) column, with methanol-0.2% glacial acetic acid as mobile phase with gradient elution at a flow rate of 1 mL x min(-1). The temperature was maintained at 30 degrees C and the detected wavelength is 260 nm, Thirteen chromatographic peaks were extracted as the common peaks of the fingerprint of P. emblica, and eleven as the common peaks of P. emblica tannin parts, and five peaks were identified by comparing with referent samples. The fingerprints of 8 samples were compared and classified by similarity evaluation, cluster analysis and principal component analysis (PCA). The similarity degrees of eight P. emblica were between 0.763 and 0.993, while tannin parts were between 0.903 and 0.991. All the samples of P. emblica and their tannin parts were classified into 3 categories. The method was so highly reproducible, simple and reliable that it could provide basis for quality control and evaluation of P. emblica from different habitats.
