OBJECTIVEIn this study, five heavy metals contamination of soil and different parts of Panax notoginseng in the plantation area was investigated. Analysis of heavy metals correlation between the planting soil and P. notoginseng; and the absorption and accumulation characteristics and translocation of soil heavy metals by P. notoginseng plants was revealed.

METHODThrough field investigation and laboratory analytical methods, analysis of China's 30 different soil P. notoginseng origin and content of heavy metals in five different parts of the P. notoginseng plant content of heavy metals.

RESULTThe results revealed that the soil heavy metals should not be neglected in the plantation area Referring to the national soil quality standards (GB15608-1995), the excessive degree of soil heavy metals pollution showed Hg > As > Cd > Cr in the plantation area, and Pb content of soil was in the scope of the standard. Refer to 'Green Industry Standards for Import and Export of Medical Plants and Preparations', the excessive degree of heavy metals content of P. notoginseng plants showed As > Pb > Cr > Cd, and Hg content of plants was in the scope of the standard. Concentrations of five heavy metals of underground parts of P. notoginseng plants are higher than aboveground, and heavy metals elements are more concentrated in the root, followed by the rhizome of P. notoginseng plants. Heavy metal accumulation characteristics of the different parts of the P. notoginseng of the overall performance is the root > the rhizome > the root tuber > leaves > stems. From the point of view BCF value analysis of various parts of the P. notoginseng plants to absorb heavy metals in soil, BCF values of all samples were less than 1, description P. notoginseng not belong Hyperaccumulator. From the view of transportation and related analysis of the soil-P. notoginseng systems, the rhizome of P. notoginseng and the content of As and Cr in soil was significantly correlated, the root of P. notoginseng and the content of Cd in soil was significantly correlated, and no significant correlation between the other indicators. Through the analysis of transportation transfer coefficient showed: Pb, As and Cr are not easy to transport aboveground part from the underground, but Cd and Hg are relatively easy to transport stems from rhizome, the migration of five heavy metals in the aerial part is relatively strong, and heavy metal of stems is easily transported to the leaves.

CONCLUSIONP. notoginseng does not belong to the enrichment of heavy metals in crops, especially for Hg in soil with strong patience. In survey area, the content of heavy metals of P. notoginseng's planting soil is relatively high, and the heavy metals As, Pb, Cr, Cd of P. notoginseng also exist heavy metals exceeded problems. Due to the presence of heavy metals in crops internal absorption and translocation of special laws, accumulation of heavy metals varied significantly in different parts of P. notoginseng. The overall, the performance for the heavy metal content of the underground parts is more than aboveground, it explain heavy metals of P. notoginseng plants is still the main source of the soiL Therefore, the key to control of planting area soil environmental quality and reduce exogenous harmful substances secondary pollution of soil in the cultivation process are to study and solve the heavy metals pollution problem of P. notoginseng.

Objective To investigate the clinical manifestions, pathological features and diagnosing methods of Lafora disease. Methods The chnical and pathological features of 5 patients with Lafora disease who were diagnosed by axillary biopsies were systemically studied. The specimen were stained by HE, PAS and AB-PAS methods. Results Four of 5 cases had an onset during adolescence and 1 during adulthood. All cases presented with progressive generalized tonic-clonic seizure, myoclonus and dementia. Emotional disturbance, dysarthria and ataxia appeared in the early course of the disease. Lafora bodys were identified in myoepithelial cells and duct cells of both eccrine sweat glands and apecrine sweat glands in the biopsies of axillary skin. Conclusions Lafora disease could be confirmed by round and oval periodic acid-Schiff- positive inclusions in skin biopsy specimen combined with the proper clinical settings. Both axillary and other skins can be chosen as the sites of biopsy.

BACKGROUND: Proliferation and differentiation of mesenchymal stem cells (MSCs) is associated with platelet concentration in platelet-rich plasma (PRP). Low enrich multiple cannot reach proper effects, but high level had inhibitory effects on osteoanagenesis.OBJECTIVE: To observe the effect of different volume fraction of PRP on dog BMSC proliferation.DESIGN: A cytological in vitro study.MATERIALS: Healthy 12-month male Beagle dogs were supplied by the Experimental Animal Center, Xiangya Medical College,Central South University.METHODS: Dog BMSCs of 5 passage were adjusted to 3×10~8/L, and incubated in a 96-well plate at 200 μL per well. Following 24 hours of routine culture, primary medium and non-adherent cells were discarded. Prepared PRP gel was mixed with serum-free low-glucose DMEM containing penicillin and streptomycin, and then diluted into 5%, 6.25%, 7.5%, 8.75%, 10% volume fraction. 200 μL above-described liquid was added into the 96-well plate, which was subsequently placed in a incubator.We set up a blank control.MAIN OUTCOME MEASURES: MTT was used to investigate effect of different volume fraction of PRP on dog BMSC proliferation.RESULTS: Compared with the blank control group, various volume fraction of PLP could promote dog BMSC proliferation in early stage. With prolonged time, proliferation speed began to increase at day 6 in the 8.75% and 10% PRP groups, entering platform stage. BMSC number was increased rapidly in the 5% and 6.25% PRP groups, especially in the 6.25% PRP group.CONCLUSION: PRP gel could promote BMSC proliferation markedly and proliferation strength of BMSCs was correlated to the density of PRP. BMSC proliferation would be accelerated by the low density of PRP.

BACKGROUND: Platelet-rich plasma (PRP) contains abundant growth factors that were needed for osteanagenesis. Moreover,the proportion of each growth factor formed by an organism, with good synergism.OBJECTIVE: To explore the influence of PRP on osteogenetic activity of canine bone marrow mesenchymal stem cells (BMSCs) after induction in vitro.DESIGN, TIME AND SETTING: The in vitro cytological experiment was performed at the Central Laboratory of Xiangya Hospital of Central South University from June 2007 to February 2008.MATERIALS: Healthy 12-month male Beagle dogs were supplied by the Experimental Animal Center, Xiangya Medical College,Central South University.METHODS: The 3~(rd) generation BMSCs were collected and divided into 4 groups. BMSCs in the control group were incubated in standard medium. BMSCs in the osteogenetic induction medium group were incubated in high-glucose DMEM containing fetal calf serum, dexamethasone, beta-sodium glycerophosphate and vitamin C. BMSCs in the PRP group were incubated in low-glucose DMEM containing 6.25% PRP. BMSCs in the combination group were incubated in high-glucose DMEM containing 6.25% PRP, dexamethasone, beta-sodium glycerophosphate, and vitamin C.MAIN OUTCOME MEASURES: Alkaline phosphatase activities were measured. Expression of collagen type I was examined by immunocytochemical staining. Calcium tuberoses were labeled using modified Von Kossa staining. Expression of osteocalcin mRNA was examined by RT-PCR.RESULTS: Levels of alkaline phosphates of all groups became increased along with time. The alkaline phosphates level of combination group was strongest (P < 0.05). Following 7 and 14 days of induction, type I collagen expressed positively in the osteogenetic induction medium and combination groups, but negatively in the PRP and control groups. Following 14 days,formation of calcium nodules were found in the osteogenetic induction medium and combination groups. Following 7 and 14 days,expression of osteocalcin mRNA were similar between the control and PRP groups (P > 0.05), which was significantly lower than the osteogenetic induction medium and combination groups (P < 0.05). Expression of osteocalcin mRNA was significantly lower in the osteogenetic induction medium group compared with the combination group (P < 0.05).CONCLUSION: PRP gel can effectively promote osteoblastic effect of BMSCs after induction in vitro following induction in osteogenetic medium.

OBJECTIVETo observe the effects of Xiongshao Capsule (XSC) on blood vessel collagenase gene expression in experimental rabbits with arterial restenosis, and to probe its mechanisms for preventing restenosis.

METHODSRestenosis rabbit model was established by injuring endothelium of abdominal aorta by balloon dilation and feeding with high fatty diet for 6 weeks. Eighty rabbits were randomly allocated into 8 groups, Group A, normal rabbit for control; Group B, rabbit with simple injured arterial endothelium; Group C, model rabbits at different times after modeling (3 days for Group C1, 2 weeks for Group C2, and 6 weeks for Group C3); Group D, model rabbit treated with Probucol for 6 weeks; Group E and F, model rabbit treated with small and large dose of XSC respectively. The effect of XSC on collagenase gene expression during the course of restenosis was observed adopting RT-PCR method and computer image analyzer, and its mechanisms in preventing RS were probed by combined analyzing the change of collagen and patho-morphological examination.

RESULTSCompensatory dilation of lumens appeared at the end of the 2nd week; while 6 weeks after modeling, the diameters of lumens obviously diminished with an apparently increased proliferation index. The cell proliferation inhibiting effect in Group D and F was significant. The total amount of collagen increased and reached the peak at the 2nd week but without conspicuous accumulation on intima, which increased gradually and reached its peak at the 6th week. In Group D-F, especially in Group F, the amount of collagen in vascular wall (intima, media and externa) was lesser than that in Groups C. MMP-1 mRNA showed weak expression in Group A and Group C1-C3; significant difference only existed in comparing Group F with C3 (P < 0.05).

CONCLUSIONXSC could markedly increase the MMP-1 mRNA expression in injured portion of vessels, suggesting that its action in preventing RS might be related with the up-regulating of MMP-1 mRNA expression, increasing collagen degradation and reducing collagen deposition in vascular wall.

Objective To explore the relationship between asthma exacerbation and respiratory tract infections of viruses,Mycoplasma pneumoniae(MP),Chlamydia pneumoniae(CP)in children.Methods Seven viruses including respiratory syncytial virus(RSV),adenovirus(AdV),influenza virus A(IFVA),influenza virus B(IFVB) and parainfluenza virus Ⅰ,Ⅱ,Ⅲ(PFVⅠ,Ⅱ,Ⅲ) from the nasopharyngeal aspirate of 74 patients with asthma were rapidly diagnosed by direct immunofluorescence assay,as well as the serum MP-IgM,CP-IgM were detected by the granule agglutinating method and indirect solid-phase enzyme immunoassay(EIA),respectively.Results Pathogens were detected in 29 out of 74 cases(39.2%) with asthma exacerbation.Of whom 14 cases(43.8%) were in infant and another 15 cases(18.8%) were in preschool and school children.RSV was the leading pathogen in infant,it was discovered in 6 cases(accounting for 18.8%).The se-cond pathogen was PFVⅢ which was discovered in 4 cases(12.5%).MP,AdV and CP accounted for 6.25%,3.1%,3.1%,respectively.But in preschool and school children,MP was the most common pathogen which were discovered in 9 cases(21.4%),the following pathogen was CP which was discovered in 3 cases(7.1%),PFVⅢ and RSV only accounted for 4.8%,2.4%,respectively.There was significant differences statistically between two groups in viral respiratory tract and atypical-microorganism infections rate(Pa

BACKGROUNDProteins or peptides can be directly transferred into cells when covalently linked to protein transduction domains (PTDs). TAT is one of the most widely studied PTDs. The effect of fusion protein TAT and heme oxygenase-1 (HO-1) on liver sinusoidal endothelial cells (SECs) apoptosis during cold storage is unknown. The present study aimed to determine whether fusion protein TAT-HO-1 would transduce efficiently into liver during cold storage, and, if so, to determine whether TAT-HO-1 would attenuate SECs apoptosis during preservation injury in rat.

METHODSLivers of Sprague-Dawley rats were harvested and randomly assigned to group 1 (HTK solution) and group 2 (HTK solution containing TAT-HO-1 fusion protein) according to the type of the preservation solution. The transduction efficiency of TAT-HO-1 was examined and the impairment of SECs was assessed during the period of cold storage followed by 1 hour of reperfusion.

RESULTSTAT-HO-1 can transduce efficiently into liver during cold storage. A significantly lower apoptotic index of SECs was observed in group 2, at 6, 12 and 18 hours of cold storage after 1 hour reperfusion, when compared with group 1. TAT-HO-1 reduced HA and ET levels in liver at each time point. Both Bcl-2 and Bax protein were expressed in hepatocytes and SECs at the periphery of the sinusoidal space. Moreover, higher Bcl-2 expression and lower Bax expression were observed in group 2.

CONCLUSIONSTAT-HO-1 can transduce efficiently into rat livers and shows a protective effect on SECs by attenuating apoptosis during cold ischemia/reperfusion injury. Protein transduction will be a novel therapeutic strategy to reduce the risk of preservation injury in liver transplantation.
