Objective To evaluate the clinical effect of the reversed saphenous fasciocutaneous island flap combined with the VSD therapy in plate exposure of the distal tibia.Methods From January 2008 to July 2010,seven patients with hardware exposure following internal fixation of the distal tibia fracture were treated by VSD therapy and reversed saphenous fasciocutaneous island flap reconstruction.The VSD therapy was performed from 7 to 26 days after hardware exposure,and the flap transfer was performed 7 to 14 days after the VSD therapy.The size of the soft-tissue defect ranged from 4 cm × 2 cm to 13 cm × 4 cm.The mean follow-up was 10.6 months after the fracture (range,8-14 months).Results The average times of the VSD therapy was 1.3.After VSD was removed,the exposed hardware was covered by healthy granulation tissue in all cases.All flaps were successfully transplanted,and the size of flap ranged from 6 cm × 3 cm to 15 cm × 6 cm.Six of 7 flaps survived completely without further procedures.The necrosis of the distal margin of the flap occurred in 1 patient.A solid bony union was confirmed by the X-ray in all patients after 4-6 months postoperatively.No skin defects or fistulae were observed.Conclusion The combination of the reversed saphenous fasciocutaneous island flap and VSD therapy could save the exposed hardware and cover the soft tissue defects in the distal tibia.

Objective To study the efficacy and safety of tacalcitol combined with monochromatic excimer light (MEL) 308 nm vs MEL 308 nm monotherapy in treating vitiligo.Methods Thirty-eight pa- tients with vitiligo were enrolled in the single-blind clinical trial,using plabebo-treated lesions in the same patient as controls.Contralateral or nearby lesions were randomly selected to be treated by either tacalcitol or placebo.All lesions were treated weekly with MEL 308 nm,for a total of 12 sessions.Patients were ex- amined at monthly intervals.The mean number of sessions and the cumulative dosage for initial and excel- lent repigrnentation were calculated.Results Thirty-five patients were evaluated.The mean?SEM cumu- lative dose and number of MEL exposures for initial repigmentation,respectively,were 4.27?3.59 J/cm~2 and 4.89?3.16 on tacalcitol-treated site,5.36?4.12 J/cm~2 and 5.69?3.29 on placebo-treated site,re- spectively (both P＜0.05).For excellent repigrnentation,the cumulative dose and number of exposures were 7.72?5.64 J/cm~2 and 7.79?4.70 respectively on tacalcitol-treated site,and 8.18?4.87 J/cm~2 and 8.4?3.92 respectively on placebo-treated site (both P＞0.05).Treatment with tacalcitol resulted in a sig- nificantly higher percentage (71.4% vs 54.3%) of repigmentation than that with placebo.Conclusions Our results show that MEL 308 nm is safe and effective for the treatment of vitiligo.Additionally,concur- rent topical tacalcitol potentiates the efficacy of MEL 308 nm in the treatment of vitiligo;this combination achieves more rapid pigmentation with a lower total MEL dosage.

Objective To explore the impacts of over-expression of microRNA-7 (miRNA-7) on the sensitivity of cis-platin in esophageal carcinoma cell line TE-1, and the possible mechanism thereof. Methods Lipofectmin 2000 method was used to transient transfect with miRNA-7 mimic into esophageal cancer cell line TE-1, which was taken as transfection group, mimic negative control was taken as transfection conrtol group. The expressions of miRNA-7 and epidermal growth factor receptor (EGFR) mRNA were detected by RT-PCR in the above two groups and normal control group. The total EGFR and EGFR in cytoplasmic and nucleus were detected with Western blot assay in transfection group and transfection control group. CCK-8 was used to detect IC50 of cisplatin in transfection group and transfection control group. The expression of EGFR was observed with immunofluorescence confocal microscope in two groups. Results The miRNA-7 expression was signifi-cantly increased in transfection group than that of transfection conrtol group and control group. The expression of EGFR mRNA was significantly reduced in transfection group (P<0.001). The total EGFR was significantly decreased in transfec-tion group than that of transfection conrtol group. The level of nuclear EGFR was significantly increased ( P<0.01),and cyto-plasm EGFR expression was significantly decreased in transfection group than that of transfection control group ( P<0.05). CCK-8 results showed that after the over expression of miRNA-7 in TE-1, the IC50 of cisplatin (48 h) increased in transfec-tion group than that of control group (P<0.01). Immunofluorescence results showed that EGFG in nuclear was higher in transfection group than that of transfection control group but its expressions reduced in cell membrane and cytoplasm. Con-clusion The over-expressed miRNA-7 in esophageal cancer cells TE-1 can reduce cisplatin sensitivity by the increased EGFR in nuclear translocation.

Objective To study the white matter fiber integrity in patients with posttraumatic stress disorder by using MR diffusion tensor imaging (DTI).Methods Twelve patients with posttraumatic stress disorder and twelve healthy volunteers were examined with MR T1WI、T2WI and DTI.Fractional anisotropy maps、directionally encoded color maps were created with the software of DTV-II.Fractional anisotropy (FA) were measured in the genu (anterior),body and splenium (posterior) of corpus callosum,horizontal part and posterior part of the bilateral cingulste fibers.Results In normal volunteers group,FA measurements in white matter regions were normal and reconstructed FA images and directionally encoded color(DEC) maps could display main white fibers in normal controls.The FA value of the splenium (posterior) of corpus callosum and horizontal part of the bilateral cingulate fibers was significant lower in PTSD patients than in normal controls (P<0.05).Conclusions The fiber bundle of the limbic system in patients with PTSD may have structural abnornalities.

Objective To compare the relative efficacy and quality of extraction of human fecal DNA using four methods.Methods Real-time PCR were utilized for analysis both quantification and quality of the fecal targeted bacteria(including gut all eubaeterium,Bacteriodes-PrevoteUa group,Bifidobacterium spp Enterobacteriaceae and Enterococcus spp)by using 16s rRNA gene-targeted genus or group-specific primer sets.Results The negative rat of PCR product from method 3(phenol-chloroform plus bead-beating) was about 40%(4/10)by using universal primers,the PCR inhibition disappeared after fecal DNA purified with column.The total fecal 16s rRNA gene copy numbers(per gram of wet weight of feces)as well as the numbers of Bacteriodes-Prevotella group from method 1(QIAamp~DNA stool mini kit)and 4(QIAamp~ DNA stool mini kit combined with bead-beating)was higher significantly than that from method 2(FastDNA ~Kit,Biol01)and 3(P

OBJECTIVETo investigate cell apoptosis, mitochondrial membrane potential, cytochrome C and mechanisms of mitochondria in lymphocyte apoptosis of sepsis.

METHODSIn the research, female C57BL/6 mice whose body weight ranged from 17 to 25 grams were utilized and assigned randomly to two groups: sham operated group (Control), cecal ligation and puncture group (CLP). The present study was undertaken by using the mice splenic lymphocyte to investigate cell apoptosis, mitochondrial membrane potential, cytochrome C. The apoptosis alteration was evaluated by Annexin V-FITC/PI double staining with flow cytometry. The alteration of mitochondrial membrane potential was investigated by Rhodamine-123 staining of cells. Cytochrome C of mitochondria and cytosol was investigated by Western blot methods. Statistical analysis was performed using SPSS 11.5 for Windows software. Experiment data was indicated with mean ± standard.

RESULTSThe splenic lymphocyte apoptosis was significantly accelerated in the CLP group when compared with that in control group (17.3% ± 2.2% vs. 3.5% ± 0.5%, P < 0.05). The Rhodamine-123 fluorescent intensity in splenic lymphocyte apoptosis was reduced in CLP group (76.2% ± 1.6%). Comparison between sham group (99.6% ± 0.4%) and CLP group had statistical significance (P < 0.05). Apoptosis could induce mitochondrial cytochrome C release into cytoplasm. In the CLP group, elevation of cytochrome C in cytosol was concurrently in accordance with decline in mitochondrial cytochrome C content.

CONCLUSIONThese data suggest that mitochondria and mitochondria signal pathway play an important role in lymphocyte apoptosis of sepsis.

OBJECTIVETo explore the effect of Qiling Decoction (QD) combined highly active antiretroviral treatment (HAART) on expression levels of peripheral blood Th17 and Treg cells in HIV/AIDS patients.

METHODSTotally 55 HIV/AIDS patients were randomly assigned to the treatment group (28 cases) and the combination group (27 cases). Besides, 21 HIV negative patients were recruited as the healthy control group. Those in the treatment group received HARRT alone, while those in the combination group received HAART combined QD. The observation lasted for 24 weeks. Meanwhile, according to peripheral blood CD4+ T cell counts before treatment, HIV/AIDS patients were assigned to three subgroups. For patients in subgroup 1, 1 cells/microL < CD4+ T cell counts < or = 100 cells/microL; For patients in subgroup 2, 101 cells/microL < CD4+ T cell counts < or = 200 cells/lL; For patients in subgroup 3, 201 cells/microL < CD4+ T cell counts < or = 350 cells/microL. Expression of peripheral blood Th17 and Treg cells, and number of CD4+ T cell counts were detected using flow cytometry (FCM)in HIV/AIDS patients at the pre-treatment baseline, week 4, 12, and 24, as well as those in the healthy control group.

RESULTSCompared with the healthy control group, CD4+ T cell counts and the baseline expression level of Th17 cells in the peripheral blood of HIV/AIDS patients significantly decreased, the expression level of Treg cells significantly increased P < 0.01). Compared with before treatment in the same group, CD4+ T cell counts all increased at week 4, 12, and 24 in the two treatment groups, showing statistical difference (P < 0.05, P < 0.01). There was no statistical difference in the effective rate at various CD4+ T cell levels between the two groups (P > 0.05). There was no statistical difference in expression levels of Th17 and Treg cells between the combination group and the treatment group at any time point (all P >0.05). The Th17/Treg ration significantly increased in the combination group after 24 weeks of treatment, showing statistical difference when compared with the treatment group (U = 2.135, P = 0.038).

CONCLUSIONQD could improve the immune balance of Th17/Treg cells, which might be one of its mechanisms for improving HIV/AIDS patients' immunity.

Objective To analyze the molecular epidemiological characteristic of rubella virus strains isolated in Zhejiang province from 2005 to 2010, to provide basic data for rubella prevention and control. Methods Rubella virus strains were isolated on Vero cells from the suspected patients' specimens collected in Zhejiang province during 2005 to 2010. Partial fragments of the structural gene of Zhejiang rubella strains were amplified, using nested reverse transcription-polymerase chain reaction (RT-PCR). The amplified products were sequences and analyzed.Results In total, 7 rubella strains were isolated from 52 clinical specimens, of which six were classified as genotype I E and only one was characterized as genotype 2B. In the phylogenetic tree, the Zhejiang IE genotype rubella strains were located in the same branches with Hongkong or Hainan isolates respectively, but the Zhejiang 2B genotype strain were located in the same branch with oversea strain BuenosAires.ARG/46.08. Through p-distance analysis, results also showed that the Zhejiang 2B genotype strain was closer to the 2B strains isolated from overseas (0.011 ) than those strains from other provinces of China (0.023). Compared with Chinese vaccine strain BRD Ⅱ, the homology on three structural genes was C＞E2＞E1, but the homology of deduced amino acid sequence was E1 ＞ C ＞ E2, with corresponding 3,11 and 23 amino acid mutations. There was only one amino acid on E1 gene with entropy value higher than 0.600, but seven sites on E2 gene with entropy value appeared higher than 0.600 and one with entropy value higher than 1.000. Conclusion Two genotypes of rubella virus had circulated in Zhejiang province during 2005 to 2010. Genotype IE appeared to be the predominant genotype and 2B being an imported one. Amino acid sequence of E1 gene from Zhejiang rubella strains was comparatively conserved, but E2 gene was hypervariable.Study on rubella virus E2 and C gene should be conducted in the epidemiological surveillance program of rubella.
