BACKGROUND/OBJECTIVES: The objectives of this study were to investigate the effects of lycopene on the migration, adhesion, tube formation capacity, and p38 mitogen-activated protein kinase (p38 MAPK) activity of endothelial progenitor cells (EPCs) cultivated with high glucose (HG) and as well as explore the mechanism behind the protective effects of lycopene on peripheral blood EPCs. MATERIALS/METHODS: Mononuclear cells were isolated from human peripheral blood by Ficoll density gradient centrifugation. EPCs were identified after induction of cellular differentiation. Third generation EPCs were incubated with HG (33 mmol/L) or 10, 30, and 50 microg/mL of lycopene plus HG. MTT assay and flow cytometry were performed to assess proliferation and apoptosis of EPCs. EPC migration was assessed by MTT assay with a modified boyden chamber. Adhesion assay was performed by replating EPCs on fibronectin-coated dishes, after which adherent cells were counted. In vitro vasculogenesis activity was assayed by Madrigal network formation assay. Western blotting was performed to analyze protein expression of both phosphorylated and non-phosphorylated p38 MAPK. RESULTS: The proliferation, migration, adhesion, and in vitro vasculogenesis capacity of EPCs treated with 10, 30, and 50 microg/mL of lycopene plus HG were all significantly higher comapred to the HG group (P < 0.05). Rates of apoptosis were also significantly lower than that of the HG group. Moreover, lycopene blocked phosphorylation of p38 MAPK in EPCs (P < 0.05). To confirm the causal relationship between MAPK inhibition and the protective effects of lycopene against HG-induced cellular injury, we treated cells with SB203580, a phosphorylation inhibitor. The inhibitor significantly inhibited HG-induced EPC injury. CONCLUSIONS: Lycopene promotes proliferation, migration, adhesion, and in vitro vasculogenesis capacity as well as reduces apoptosis of EPCs. Further, the underlying molecular mechanism of the protective effects of lycopene against HG-induced EPC injury may involve the p38 MAPK signal transduction pathway. Specifically, lycopene was shown to inhibit HG-induced EPC injury by inhibiting p38 MAPKs.

Objective To explore the distribution of arsenic speciafion and to estimate the effect of arsenic on glutathione(GSH)levels in the blood and liver of mice exposed to different concentrations of inorganic AsⅢ through drinking water.Methods Mice drank water containing arsenite at concentrations of iAsⅢ of 0(contr01),25,50,100 ms/L for 6 weeks.Blood and liver were sampled to asses$the levels of inorganic arsenic(iAs),monomethylarsenic acid(MMA),dimethylarsenic acid(DMA)by the method of hydride generation trapping and ultra-hypothermia coupled with atomic absorption spectrometry,and the level of GSH by the method of 5,5'-Dithio-bis (2-Nitrobenzoic acid).Results Leveh of iAs.MMA and DMA in blood and in liver increased along with the increase of iAs concentrations in drinking water.Primary methylated index(PMI)and secondary methylation index (SMI)of liver and blood were significantly higher in exposed groups than those in control group(P＜0.05).SMI of liver in 50 mg/L exposed group[(50.45±2.94)%]was significantly higher than those in 25 mg/L and 100 mg/Lgroups[(41.68±7.09)%and(41.19±8.87)%,respectively],the difference being statistically significant(P＜0.05).The ratio of iAs.MMA and DMA in blood and liver in exposed group were 2:3:5 and 4:3:3,the percentage of level of organic arsenic(MMA+DMA)were 80%and 60%.GSH in blood and liver in exposed group decreased along with iAs concentrations in drinking water and had significant differences compared with those in control group (P＜0.05).However,levels of GSH in liver and blood did not differ significantly between exposed groups and control group(P＞0.05).Conclusions Membolism of iAs in liver is maximized when the iAs concentrations in drinking water increases to a certain level.However,the percentage of arsenic speciation in blood is different from that in liver,suggesting that other organs and tissues may be capable of methylation of inorganic arsenic.The level of GSH in liver and blood in mice is a good mark tO reflect the toxicity of arsenic.

Objective: To observe the effects of acupuncture plus spinal manipulations on the physical functioning and levels of alkaline phosphatase (ALP), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and osteoprotegerin (OPG) in patients with ankylosing spondylitis (AS). Methods: A total of 128 AS cases were allocated into a control group and an observation group using random number table method, with 64 cases in each group. Patients in both groups took sulfasalazine and meloxicam. Patients in the observation group received additional acupuncture plus spinal manipulations. The efficacy, Bath AS functional index (BASFI), Bath AS disease activity index (BASDAI), and the levels of ALP, ESR, CRP and OPG were compared between the two groups after eight weeks of treatment. Results: After treatment, the symptom scores of traditional Chinese medicine in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); the VAS, BASFI and BASDAI scores in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); and the ALP, ESR, CRP and OPG levels in both groups were decreased (all P<0.05), and these levels in the observation group were significantly lower than in the control group (all P<0.05). The total efficacy rate was 92.2％ in the observation group, versus 78.1％ in the control group, presenting a statistical significance (P<0.05). Conclusion: Conventional medication combined with acupuncture and spinal manipulations can improve clinical symptoms, accelerate the recovery of physical functioning, and reduce the ALP, ESR, CRP and OPG levels.

OBJECTIVETo understand antibody responses to and RNA sequences of Hantavirus in patients with hemorrhagic fever renal syndrome (HFRS) in Yantai areas and to demonstrate the type of the prevalent viruses caused HFRS.

METHODSSerum specimens collected at acute and convalescent stages from 90 patients with HFRS and IgM and IgG antibodies against Hantavirus were detected with ELISA, and cross plaque reduction neutralizing tests were performed to detect neutralizing antibody. Viral RNA was extracted from the patients? sera by using Trizol method and nested PCR was utilized to amplify the specific segments of the viral cDNA and the products of the PCR were TA cloned and then the nucleotide sequences were determined.

RESULTSThe IgM antibody was positive in 82.2% (88/107) of the patients while the IgG antibody was positive in 85.7% (66/77) of the patients. Both the serologic and sequence analyses demonstrated that the epidemic of HFRS in Yantai areas was caused by mixed types of Hantavirus. The prevalent strains of Hantavirus had higher homology with the strains isolated in Korea than with those isolated previously in China.

CONCLUSIONSThe serologic and sequencing analyses indicated that the epidemic of HFRS in Yantai areas was caused by mixed types of Hantavirus dominated by type SEO.

OBJECTIVETo observe therapeutic effect of electroacupuncture (EA) at Jiaji (EX-B 2) combined with laser needle-knife on lumbar disc herniation.

METHODSOne hundred and twenty cases of lumbar disc herniation were divided into an Jiaji EA group, a laser needle-knife group and a combination group (Jiaji EA plus laser needle-knife) according to random number table. Changes of symptoms at different stages before and after treatment were investigated with SF-MPQ cumulative scores.

RESULTSAll the 115 cases completed all of the study, SF-MPQ score in the combination group was significantly lower than those in the Jiaji EA group and the laser needle-knife group (P<0. 01, P<0.05), with a significant difference at the end of treatment of 2 weeks (P<0.01) between the laser needle-knife group and the Jiaji EA group, and with no significant difference at treatment of 1 week and 3 weeks (P>0.05). The recurrence rate at a half year later in the combination group was significantly lower than those in laser needle-knife group and the Jiaji EA group (P<0.05).

CONCLUSIONEA at Jiaji (EX-B 2) combined with laser needle-knife can significantly increase clinical therapeutic effect, alleviate pain of the patient and reduce recurrence.

Objective To evaluate the effectiveness of post-exposure varicella vaccination in elementary schools in Beijing and to explore its influencing factors. Methods From May to July 2007, variceila cases from 49 elementary schools in 4 districts in Beijing were observed prospectively. The study included 7882 children who were from the same classrooms, same floor or same bungalow areas with the varicella cases. Vaccination status, history on varicella and onset of rashes were collected to calculate the secondary attack rate among those children under observation and then the effectiveness of vaccine was calculated. Results The protection rate on post-exposure vaccination among children under observation was 85.26%. The rates were higher when the 1st case had received varicella vaccine before the onset, vaccines were administered soon after the exposure or there were less varicella cases occurred in the schools. For children in the same class, same floor or bungalow with varicella cases before post-exposure vaccination, the average rates of protection by vaccination were 84.26% and 87.06%, respectively. When the 1st case had received varicella vaccine prior to the onset, the post-exposure protection rates reached 92.09% and 93.06%, respectively, higher than that of the case when the 1st case had received no vaccination. When the administration of vaccine right after the occurrence of first varicella case, the rates of the effectiveness of vaccine were 83.09% and 93.02%, both of which were higher than that of vaccine administered after the occurrence of 2 or 3 cases. When the vaccine administration of vaccination combined with the isolation of the already infected cases or within 5 days after the onset of the 1st case, the vaccine effectiveness could reach 86.60% and 92.73%, both were higher than otherwise. However, in those schools that bungalows were used as classrooms but without bus, canteen from school or student lodgings, it seemed that post exposure vaccination was more effective in preventing varicella from occurring. Conclusion Varicella vaccination after exposure in elementary schools in Beijing was effective in prevention and control of the disease. Immediate administration together with the isolation of cases could maximize the effectiveness of the vacine.

BACKGROUNDEstrogen might play an important role in type 2 diabetes mellitus pathogenesis. A number of polymorphisms have been reported in the estrogen receptor alpha (ERalpha) gene (also named ESR1), including the XbaI and PvuII restriction enzyme polymorphisms of ESR1, which may be involved in disease pathogenesis. The aim of this study was to determine whether ERX gene polymorphisms are associated with type 2 diabetes mellitus and serum lipid level.

METHODSTwo hundred and ninety-nine patients with type 2 diabetes mellitus were compared with three hundred and forty-one health controls of Guangzhou in China, both were male and postmenopausal female residents at 51 - 70 years. ESR1 genotyping was performed using polymerase chain reaction (PCR) and PvuII and XbaI restriction fragment length polymorphism (PCR-RFLP) analysis.

RESULTSESR1 allelic frequencies of P, p and X, x alleles were 0.408, 0.592; 0.360, 0.640 in the type 2 diabetes mellitus group and 0.318, 0.682; 0.328, 0.672 in the control group, respectively. In case-control study, there was significant difference in PvuII, but not XbaI, allele frequency between the type 2 diabetes mellitus and control groups (P = 0.001 and P = 0.122). When the group was separated into men and women, the difference was significant in women (P < 0.001) but not in men (P = 0.854) with the PvuII genotype, and the effect of PvuII variant on the development of type 2 diabetes mellitus was improved with aging. In addition, PvuII genotype was associated with blood glucose [fasting blood glucose (FBG), postprandial blood glucose (PBG)] and serum lipid [total cholesterol (TC) and low density lipoprotein (LDL)-c] concentration in healthy women.

CONCLUSIONSPvuII polymorphism of ESR1 increases susceptibility to type 2 diabetes mellitus in Chinese Guangzhou women. ESR1 variants may also impact serum lipid metabolism, which might provide a mechanism connecting ESR1 to type 2 diabetes.

Objective To investigate the phenotype, frequency and function of CD4 + T cell subsets and the relevant cytokines, as well as the relationship between these cells and appearance of pneumonia of novel (H1N1 ) influenza A patients. Methods 68 healthy people,53 confirmed novel A( H1N1 ) influenza patients without pneumonia and 16 confirmed severe novel A( H1N1 ) influenza patients with pneumonia were enrolled in this study. Viral load in nasopharyngeal swabs specimens was measured by real time PCR assay.The phenotype and percentage of CD4+ T cell subsets including Th1, Th2, Th17, and Treg cells were measured by Flow cytometry analysis. The relevant cytokines in plasma including TGF-β, IL-6 and IFN-γ were measured by ELISA. Data was analyzed by one way ANOVA. Results It was found that peak viral load and viral shedding period of severe patients with pneumonia was significantly increased compared with mild patients without pneumonia ( P ＜ 0. 05 ). The percentage of Th17 cells of severe patients with pneumonia was significantly diminished compared to that of healthy subjects and mild patients without pneumonia( P ＜ 0. 05 ). However, Th1 ,Th2, Treg cells frequencies had no significant differences ( P ＞ 0. 05 )among these three groups. The level of TGF-β in plasma for the severe patients with pneumonia was also significantly decreased compared to that of healthy subject and mild patients without pneumonia( P ＜0. 05 ).The viral shedding period inversely correlated with the frequency of Th17 cells ( r = - 0. 38, P ＜ 0.05 ).Conclusion H1N1 influenza A virus can inhibit Th17 cells to differentiate, particularly more extent in patients with pneumonia. Impaired Th17 cells may correlate with viral clearance and pneumonia of novel H1N1 influenza A patients.
