This paper describes a patient security detection system developed with two dimensional bar codes, wireless communication and removal storage technique. Based on the system, nurses and correlative personnel check code wait operation patient to prevent the defaults. The tests show the system is effective. Its objectivity and currency are more scientific and sophisticated than current traditional method in domestic hospital.

Objective To investigate the suppressive effects of collagen from Cyanea nozakii on adjuvant induced arthritis inrat.Methods Rats with adjuvant arthritis received different do- ses of Cyanea nozakii collagen by intragastric administration for two weeks.Incidence and severity of arthritis were assessed by calculation of mean arthritis index,the concentrations of NO,MDA and activity of SOD in the serum were examined.Results Cyanea nozakii colla- gen at different doses could ameliorate the adjuvant induced arthritis,suppress the concen- trations of NO,MDA and increase the activity of SOD in the serum.Conclusion Cyanea noza- kii collagen has therapeutic efficacy in treatment of adjuvant arthritis rats,and the mecha- nism of Cyanea nozakii collagen is probably related to the antioxidation.

A total of 160 type 2 diabetic patients were divided into microalbuminuria(42 cases)and normoalbuminuria(118 cases)groups.Multivariate analysis demonstrated that the presence of microalbuminuria was independently associated with brachial-ankle pulse wave velocity(baPWV)and intima-media thickness(both P

AIMTo determining whether the level of serum leptin altered and whether the expression of leptin receptor immunoreactivity changed following taste stimuli.

METHODSAfter intraoral infusions of chemical solutions, which included 3 mol/L sucrose, 5 mmol/L sodium saccharin, 0.1 mol/L NaCl, 0.01 mol/L HCl, 1 mmol/L quinine H2SO4 and 0.1 mol/L monosodium glutamate, serum leptin concentration were measured by using rat leptin RIA kit. Immunohistochemistry ABC method was used for brain sections with high-specify-goat antiserum against leptin receptors.

RESULTSComparing with the control group (intraoral infusion of distilled water), the level of serum leptin only in sweet group (sucrose an d saccharin) raised (P < 0.05). Many neuronal cell bodies and dendritic processes showed leptin receptors immunoreactivity (LR-IR) in many brain regions, such as amygdala, hypothalamus, parabrachial nucleus and nucleus of the solitary tract, which had intense relationship with taste and feeding. But the number of positive-stained cells showed no difference in aforementioned brain regions between the taste stimuli group and the control group.

CONCLUSIONAfter intraoral stimuli of sweet substances, the serum leptin concentration increased. LR-IR cells exist in amygdala which plays a critical role in the initiation and guidance of feeding. This findings led us study possible effects of leptin on taste responses. Probably, leptin influences food intake through the sense of taste.

OBJECTIVEAfter sinboneHT bone replacement (SBR) was implanted in animals, to evaluate the biocompatibility of SBR and compounded in autogenetic bone in the proportion of one to one in order to prepare for the clinical applications in the future.

METHODSBone defects of 10 mm x l0 mm x 2 mm was made at the mandibular of rabbits, then SBR with different granule diameter and autogenetic bone was compounded in the proportion of being applied in the left defects, while autogenetic bone was implanted in the right defects and nothing was used in the right reformed defects. Animals were sacrificed at 2, 4 and 8 weeks respectively. The biologic capacity was evaluated with anatomy, X-rays studies and histology.

RESULTSSBR has better biocompatibility, which can effectively accelerate the reconstruction of bone defects and help the new bone by being compounded with autogenetic bone. It provides the appropriate scaffold or template which would allow cellular infiltration, attachment and multiplication.

CONCLUSIONSBR is a kind of bone substitute material with good biocompatibility. SBR compounded with self-bone has a better regeneration function.

OBJECTIVETo study the validity of single plane Simpson's method with conventional X-ray ventriculography for estimation of right ventricular (RV) volume.

METHODSFifteen human RV casts were obtained from 15 subjects who died from non-cardiac causes within 24 hours after death. These casts were photographed respectively and their volumes were calculated by using the single plane Simpson's method based on a new half-circle model. The actual RV cast volumes were determined by water displacement method.

RESULTSThe actual RV volume was (64.23 +/- 24.51) ml and the calculated volume was (58.04 +/- 24.45) ml. The calculated RV volume underestimated the actual volume by (6.19 +/- 12.38) ml, but there was no significant difference between the actual and the calculated RV volume (P > 0.05). There was a significant correlation between the actual cast volume and the calculated volume (r = 0.983, P < 0.01). The regression equation was: RV actual volume = 1.074 x (RV calculated volume).

CONCLUSIONRV volume calculated by single plane Simpson's method with conventional X-ray ventriculography is accurate and deserves further study.

OBJECTIVETo evaluate the treatment of recurrent acute cholangitis with hepatolithiasis.

METHODSWe retrospectively analyzed the clinical data of patients with recurrent acute cholangitis who were treated in Peking Union Medical College Hospitals emergency department from January 1998 to December 2008.

RESULTSTotally 408 patients underwent surgery, of which 167 patients received emergency operations and 241 underwent selective operations after medication and interventional treatment. The incidence of complications was 6.4% among those who received emergency operations and 3.2% among selective operations. The 30-day mortality rate of selective operations was zero.

CONCLUSIONAlong with the progress of percutaneous cholangiographic drainage and endoscopic retrograde cholangiopancreatography, selective operations have been increasingly applied for acute cholangitis with notably low complications and postoperative death.

OBJECTIVETo observe the role of Panax notoginosides (PNS) in up-regulation of GATA family transcription factors, and explore intracellular signal pathway of PNS in the proliferation of hematopoietic cells.

METHODSHuman bone marrow cells were incubated with different concentrations of PNS for colony-forming assay. Human cell lines HL-60, K562, CHRF-288 and Meg-01 were incubated with PNS (10 mg/L) for 14 days. The cell nuclear proteins were extracted and analyzed by Western blot with antibodies against GATA-1, GATA-2. Electrophoretic mobility shift assay (EMSA) and antibody gel supershift assay was performed using (32)P labeled GATA consensus oligonucleotide which contains binding site for GATA transcription factors.

RESULTSPNS could promote the proliferation of CFU-GM and CFU-E and induce the expression of GATA-1, GATA-2. The nuclear proteins of both GATA-1 and GATA-2 in K562, CHRF-288 and Meg-01 cells treated by PNS were increased by (1.5 - 2.8) and (2.0 - 3.1)-fold over untreated cells respectively. GATA binding activity initiated by PNS was apparently elevated to form higher density band of GATA-DNA complex. While there was no detectable change in HL-60 cells before and after PNS treatment. The predominant GATA binding complex was mainly attributable to both GATA-1 and GATA-2 proteins being in phosphorylated status.

CONCLUSIONPNS can induce the synthesis of transcription factors GATA-1 and GATA-2 and enhance their DNA binding activity, which could play a role in the up-regulation of the expression genes related to proliferation and differentiation in hematopoietic cells.
