AIM:To explore the molecular mechanism of panaxadiol saponin(PDS)by observing Toll like receptor(TLR)2 and TLR9 mRNA expression induced by lipopolysaccharide(LPS).METHODS:Rats were divided into LPS,LPS+PDSL,LPS+PDSM and control group,respectively.Nitric oxide synthase(NOS)activity,nitric oxide(NO)content,LPO content,SOD activity and TLR2 and TLR9 mRNA expression were assayed 4 h after intravenous injection of LPS.RESULTS:NOS activity,NO content,LPO content of LPS+PDSL group and LPS+PDSM group were significantly lower than those in LPS group.TLR2 mRNA expression in the liver tissue of LPS+PDSL group and LPS+PDSM group was decreased compared with LPS group.CONCLUSION:PDS has a protective effect on liver tissues by triggering the down-regulation of TLR2 expression,reducing NOS activity,and NO content.

Objective To explore the relationship between some single nucleotide polymorphisms (SNP)loci of interferon regulatory factor 6(IRF6)gene,transforming growth faetor-?(TGFA)gene and nonsyndromic cleft lip with or without cleft palate(NSCL/P)in nuclear families consisting of fathers, mothers and affected offspring with NSCL/P from southeast China.Methods Some SNloci of IRF6 and TGFA were detected by applying microarray technology in nuclear families,and then haplotype relative risk (HRR)and transmission disequilibrium test(TDT)were performed.Results There were no significant difference in genotypes and alleles distribution between patients and their parents.The SNP locus——V274I of IRF6 was associated with NSCL/P(HRR:?~2=4.5816,P

OBJECTIVETo observe the effects of puerarin on ADRP gene mRNA expression in fatty tissue of type 2 diabetes mellitus rats (T2DM).

METHODWiastar rats of T2DM model were made by feeding with high glucose and fat diet and injecting with small dose of streptozocin (25 mg x kg(-1)). 40 model rats were randomly divided into model control group and three puerarin groups (40, 80, 160 mg x kg(-1)), another 10 rats were selected as normal control group. FBG and FINS were measured to calculate IR after rats were injected consecutively for 6 weeks. The level of ADRP gene mRNA in fatty tissue was determined by RT-PCR after rats were injected eight weeks.

RESULTCompared with model control group, high and middle dosage of puerarin can decreased ADRP gene mRNA expression in fatty tissue obviously, FBG, IR level in each puerarin group and FINS in high and middle dosage puerarin groups decreased obviously.

CONCLUSIONPuerarin can decrease the blood glucose level of T2DM by downregulating ADRP mRNA expression and depressing the insulin resistance.

This study was aimed to investigate the effects of DMSO on platelets during pre-treatment for lyophilization, including centrifugation, washing and loading trehalose. After pre-treatment for lyophilization, the expression of platelet membrane surface glycoprotein (GP) including CD62p and PAC-1 was analyzed by FCM before and after induction with thrombin, the mean platelet volume (MPV) and platelet maximal aggregation with several platelet inducers were investigated. The results showed that the expression rates of CD62p and PAC-1, as the platelet activation signs, increased and were 30.37% and 15.01% respectively in group without DMSO after pre-treatment. And their differences in comparison with control were statistically significant, but that of CD62p was 10.72% and PAC was 10.11% in group with DMSO, in comparison with group without DMSO respectively, their differences were statistically significant after diluting with DMSO, CD62p was re-expressed to 54.39% in group with DMSO and more than that in group without DMSO and lower than control statistically significant. PAC-1 was re-expressed to 49.28% in group with DMSO and more than that in group without DMSO (p<0.01) and reached to control. Platelet maximal aggregations induced by thrombin, restocetin and propyl gallate were 92.76%, 91.24% and 89.66 respectively in group with DMSO. These were closed to that in control group and in group without DMSO. But the aggregation induced by ADP was 34.33%, it was less than control (p<0.01) and more than that in group without DMSO (p<0.01). It is concluded that DMSO can inhibit the expression of CD62p and PAC-1 on platelet in vitro. But when diluted with plasma, platelets can express CD62p and PAC-1 induced by thrombin and be led to aggregate by several inducers, so the inhibitory effects of DMSO on platelet activation are reversible. DMSO play roles in inhibitor damage from platelet activation and cryoprotectant. This property of DMSO is very important in research of platelets lyophilization.

METHODSFinancial records were used to collect the information about the fund source and allocation of the resource invested for the MSM intervention between 2006 and 2009. Key staff was interviewed to get related information. The activity-based costing method was adopted to analyze the actual expenditure of MSM intervention in different sites, and the allocation of the total cost to each activity, the intervention times in different sites and the unit cost in actual HIV testing person-times promoted by MSM intervention was then calculated.

RESULTSInterventions through internet and in bar and bathhouse were conducted in the certain city. Total funds for MSM intervention between 2006 and 2009 were 4.441 million, 56.7% (¥2.530 million) of which were from international cooperation programs, whose direct cost covered 50.5% (¥2.243 million) of the total cost. The actual expenditure in interventions through Internet was ¥750 656 (16.9%), including direct expenditure ¥317 088 and indirect expenditure ¥433 568. The actual expenditure in interventions in bar was ¥2 061 846 (46.4%), including direct expenditure ¥1 114 423 and indirect expenditure ¥947 423. The actual expenditure in interventions in bathhouse was ¥1 628 751 (36.7%), including direct expenditure ¥811 474 and indirect expenditure ¥817 277. The person-times of receiving MSM intervention and the unit cost for promoting HIV test through the above 3 access all decreased. The average cost for one person-time intervention through internet and in bar and bathhouse decreased from ¥68.7 (1011 person-times), ¥67.3 (3282 person-times), ¥67.9 (3140 person-times) in 2006 to ¥40.9 (25 523 person-times), ¥30.2 (28 121 person-times), ¥17.5 (28 381 person-times) in 2009 respectively, and the cost for promoting one person-time HIV test decreased from ¥1789.2 (58 person-times), ¥1175.6 (188 person-times), ¥574.2 (312 person-times)per person time to ¥676.9 (394 person-times), ¥556.5 (1637 person-times), ¥316.5 (2237 person-times) respectively.

CONCLUSIONThe unit cost of MSM intervention through internet and in bar and bathhouse decreased, as well as the cost for HIV test promotion per person-time in the city. Meanwhile, the intervention covered more and more people annually.

OBJECTIVEContinuous spike-and-wave during slow wave sleep (CSWS) syndrome is one of the presentations of electrical status epilepticus during sleep (ESES). The purpose of this study was to investigate the characteristics of CSWS syndrome in children.

METHODSBetween 2007 and 2009, a total of 778 nocturnal long-term or 24-hr video-EEG records were included. The EEG, clinical and neuroimaging characteristics were studied in children who met standard criteria for CSWS.

RESULTSNine children met standard criteria for CSWS in video-EEGs. Their ages ranged 6 to 13 years. Their EEGs were characterized by continuous spike-and-wave (SW) discharges during non-rapid eye movement (NREM) sleep, accounting for 85%-100% of the period of NREM sleep. Clinically, these children had various types of epileptic seizures and exhibited different degrees of neuropsychiatric impairments, language dysfunction, and/or behavioral disturbances. Neuroimaging abnormalities were found in 6 cases, including atelencephalia or atrophy, gray matter heterotopia and leucomalacia.

CONCLUSIONSThis study indicates the characteristics of CSWS syndrome in clinical manifestations, EEG and neuroimaging examinations. This will be helpful in understanding CSWS syndrome.

BACKGROUND: With the improvement of medical imaging technology, the visualization of human anatomy has been further developed; the role of three-dimensional (3D) reconstruction in medical treatment is also becoming increasingly prominent. Mimics is the most widely used medical image reconstruction software. Arigin 3D Pro is a recently developed 3D reconstructed medical software system based on 3D printing. OBJECTIVE: To study the accuracy of 3D reconstruction models obtained by using Arigin 3D Pro and Mimics with medical images. METHODS: The image data of liver, spine, knee joint and heart were selected, and the deviations of two software reconstruction models were analyzed based on the 3D model reconstructed by Mimics. Totally 10 cases of skull and 1 case of femoral comminuted fracture image data were selected and reconstructed. Each reconstruction model was measured with 10 groups of feature sizes to evaluate the differences between the two software programs. RESULTS AND CONCLUSION: Arigin 3D Pro and Mimics were used to reconstruct the liver, spine, knee and heart data. The mean ± standard deviation of model deviations were (0.93 ± 1.05), (0.36 ± 0.74), (0.45 ± 0.74), (0.18 ± 0.41) mm. It took 3 minutes and 35 minutes for Arigin 3D Pro and Mimics to reconstruct the liver model respectively, and both software reconstructed other models for less than 1 minute. There was no statistically significant difference between the feature sizes of the two software for the 3D reconstruction models of skull and femoral comminuted fracture data (P > 0.05). The 3D reconstruction model of Arigin 3D Pro is comparable to that of Mimics. For the liver model, the reconstructed time of Arigin 3D Pro is significantly shorter than that of Mimics.
