OBJECTIVETo observe the immediate analgesic effect of tendon acupuncture on soft tissue injury in different sites.

METHODSA total of 140 cases of soft tissue injury, involving 14 injury sites, were treated with tendon acupuncture. According to the principle of "considering pain as acupoint", based on injury sites, one to three tendon acupoints were selected in each tendon, which were treated with 1 to 5 times. Totally 676 times Of treatment was given. The visual analogue scale (VAS) was used to evaluate the immediate. analgesic effect before and after the treatment.

RESULTSAfter the treatment, the score of VAS was significantly reduced (4. 20+ 1. 77 vs 2. 43 ± 1. 30, P<0. 001); regardless of the total number of treatment, the score of VAS after each acupuncture was obviously reduced compared with that before acupuncture (all P<0. 001); the score of VAS at each injury sites after treatment was significantly reduced compared with that before treatment (all P<0. 001).

CONCLUSIONThere is an immediate analgesic effect of tendon acupuncture for different sites of soft tissue injury. Also, the effect has been shown in different frequencies of treatment.

Objective To investigate the clinical effect of porcelain fused for metal crown restoration after root canal therapy.Methods Totally 90 patients with pulpitis or periapical periodontitis from December 2013 to December 2015 had their clinical data analyzed,who underwent root canal therapy and were divided equally into an observation group and a control group.The observation group took porcelain endocrowns repair and the control group applied ceramic crown.The two groups were compared on the restoration integrity,edge sealing,residual rate,gum,food impaction and color 3 months,6 months and 1 a after treatment.Results The observation group behaved significantly better than the control group in the edge sealing and restoration integrity (P＜0.05).There were significant differences between the residual rates,gum and food impaction in the two groups (P＜0.05).Conclusion Porcelain endocrowns repair gains advantages over ceramic crown repair in edge sealing,integrity,gum,food impaction and color after root canal therapy,though its long-term effect needs further investigation.

Aim:To investigate the effect of Hemangiopoietin (HAPO) on the hematopoiesis reconstitution in sub-lethally irradiated Balb/c mice.Methods: Balb/c mice were underwent total body irradiation at 700 cGy 137Cs ? radiation and were treated with HAPO or recombinant human granulocyte colony stimulating factor (rhG-CSF) after irradiation. The hematopoiesis reconstitution of mice were detected. Cells from bone marrow of Balb/c mice were cultured with HAPO or rhG-CSF for 24 hours or 72 hours before or after the cells were irradiated. The viability of cells were assessed and the ability of in vitro hematopoiesis reconstitution were also detected. Result: rhG-CSF and HAPO treated mice both showed increased survival rate and increased colony forming units. The peripheral WBC number increased greatly. The HAPO group was most quickest compared with rhG-CSF group and PBS control group. The number of bone marrow cells at day 14 of rhG-CSF group was higher than that in HAPO group, but the number of bone marrow cells at day 32 of rhG-CSF was lower than that in HAPO group. The number of bone marrow cells at day 42 of rhG-CSF was below normal. The number of bone marrow cells at day 42 of HAPO group was nearly normal. The number of CFU-GEMM in HAPO group was most compared with that in rhG-CSF group and PBS control group at day 7, 14 and 21 after radiation. The survival rate of cells after radiation in HAPO group was markedly higher than that in PBS control group, but the survival rate of cells after radiation in rhG-CSF group was no notable difference compared with that in PBS control group. In MTT assay, both HAPO and rhG-CSF incubation stimulated proliferation of bone marrow cell at 72 hours after radiation. Bone marrow cells formed Hematopoietic islands in HAPO group after radiation and were positive for sca-1 and CD31. CD31 positive endothelial cells increased around the Hematopoietic islands. There was no Hematopoietic islands formation, few CD31 positive endothelial cells and no sca-1 positive cells in PBS control group. Conclusion: HAPO can promote hematopoiesis reconstitution in sub-lethally irradiated Balb/c mice. It can increase the survival rate of mice and stimulate the proliferation of hematopoietic stem cells.

To explore the optimized dispatch of the rescue resources based on the mastered resources informa-tion. The objective function was set as the shortest rescue time, and 0-1 programming models were established and solved for the conditions that the number of medical rescue units was more or less than needed by the missions. In the two conditions, the model's calculated results were both optimal, and could be used to obtain the optimal dispatch solutions while the medical rescue time was the shortest. The 0-1 programming model can be effectively used to optimize dispatch strategy for medical rescue team.

Objective To observe the expression of HER-2 and TOPO-Ⅱα in ovarian epithelial cancer,analyze the correlation between their expression and provide theoretical basis for clinical diagnosis,prognosis and treatment. Methods Expression levels of HER-2 and TOPO- Ⅱα in 10 normal ovarian tissues,20 benign tumors and 58 cases of ovarian epithelial cancers were detected by immunohistochemical method, and their correlations with pathological features were analyzed. Results The positive expression rate of HER-2 in normal ovarian and benign tumor tissues were significantly lower than ovarian epithelial cancers respectively ( 10. 0% , 15.0% VS 46. 6% ;P ＜ 0. 05 ). The positive expression rate of TOPO- Ⅱα in ovarian epithelial cancers was significantly higher than normal and benign epithelial ovarian tumor tissue (53.4% vs 10. 0%, and 15.0%,Ps ＜ 0. 05 ), but we did not find significant difference in the comparison between normal and benign epithelial ovarian tumor tissue ( Ps ＞ 0. 05 ). The expression of HER-2 and TOPO- Ⅱα were significantly correlated with clinical stages, histological differentiation of tumor cells (Ps ＜ 0. 05 ) ,but there were no correlations between the age or histological type. In ovarian cancer tissues, a positive correlation between the expression of HER-2 and TOPO- Ⅱα was observed ( r = 0. 324, P ＜ 0. 05 ) . Conclusion The overexpression of HER-2 and TOPO- Ⅱαplay an important role in ovarian carcinogenesis and development. The expression of HER-2 is positively correlated with TOPO- Ⅱα in ovarian epithelial cancers. Coexpression of the two moleculars may be involved in the development and progression of ovarian epithelial cancer, which should be further studied.

In this study, five rhesus macaques were inoculated intravenously with SIVmac251 to establish a model of simian autoimmune deficiency syndrome (SAIDS). Peripheral blood samples were collected at different time points to monitor changes in the total T cell number and T lymphocyte subset. Plasma viral loads, cytokine expression levels and anti-SIV antibody levels were also assayed to acquire certain basic indexes to evaluate disease progression in the rhesus macaque SAIDS model. During the acute stage of infection, plasma viral loads reached a peak at week 1 post-inoculation and lasted for approximately 3 to 44 weeks. The CD3+ CD4+ T lymphocyte count in peripheral blood also transitorily decreased. During the same period, the level of interferon-gamma show an increasing trend, whereas IL-12 levels decreased; IL-2, IL-4, IL-10 and TNF-alpha were maintained at normal levels or could not be detected. During the asymptomatic and ARC phases, plasma viral loads persisted above 10(4) RNA copies/mL and either increased or declined during the later stages of disease; CD3+ CD4+ counts showed a steadily declining trend and the ratio of CD4 to CD8 decreased during late-stage disease. Moreover, antibodies against viral proteins were detected in the plasma and showed a significant increasing trend, while there were no apparently changes in the levels of IFN-gamma, IL-12, IL-2, IL-4, IL-10 and TNF-alpha. In conclusion, the characteristics of the SIV animal models in our study are similar to those of patients with AIDS. Therefore, the rhesus macaque SIVmac251 infection models can be applied for further studies into AIDS.

Murine norovirus (MNV) was first discovered in mice in 2003. MNV is a member of the genus Norovirus in the family Caliciviridae. It is one of the most important and prevalent pathogens of laboratory mice, and almost all mouse strains are susceptible to MNV infection. In this study, a MNV strain was isolated from the cecal contents of infected mice and identified by the cytopathic effect (CPE) assay, virus plaque assay, 50% tissue culture infectious dose (TCID50) assay, electron microscopy, indirect immunofluorescence assay (IFA) and nucleotide sequencing. On infection, the RAW264.7 cell line showed obvious cytopathic effects within 24 to 48 hours post-inoculation, as infected cells became rounded, bright and shrunken, with ultimate disintegration of the cell sheet. After the isolation of the MNV virus, the virus was plaque-purified in RAW264.7 cells. The TCID50 of the virus was 10(5.25/0.1 mL. Electron microscopic observations of the purified virus showed the presence of spherical and non-enveloped viral particles that were 30 to 35 nm in diameter. According to the identification results, the isolate was named as MNV Guangzhou/K162/09/CHN. Thereafter, five overlapping gene fragments that covered the entire open reading frame (ORF) were amplified by RT-PCR, and the 3'-untranslated region (UTR) and 5'-UTR were amplified using the 3'-rapid amplification of cDNA ends (RACE) and the 5'-RACE method, respectively. Each of the gene fragments were cloned and sequenced, and whole genome sequences of the strain were obtained by assembling the cDNA fragment sequences. The results showed that the length of the complete genome was 7 380 nucleotides (GenBank accession number: HQ317203). The comparison of nucleotide and deduced amino acid sequences of the isolate was performed against other MNV strains in the GenBank database. A phylogenetic tree based on VP1 nucleotide sequences was constructed using MEGA5.0 software. The homology of nucleotides between the MNV Guangzhou/K162/09/CHN strain and other MNV isolates ranged from 87.4% to 89.7%. Phylogenetic analysis showed that there was a close genetic relationship between the Guangzhou/K162/09/CHN strain and MNV strains isolated from Japan (S7-P2 and S7-PP3 isolates), Korea (K4 isolate), and Germany (Berlin/04/06/DE and Berlin/05/06/DE isolates). This is the first report of the isolation and identification of MNV in China, and the first report of the genetic analysis of its complete genome.

The data mining technique is adopted to analyze characteristics and rules of acupoint and meridian selection of acupuncture-moxibustion for treatment of vertigo at different time periods in the ancient. The data is collected from literature regarding acupuncture-moxibustion from the pre-Qin period to the end of Qing Dynasty, so as to establish a clinical literature database of ancient acupuncture-moxibustion for treatment of vertigo. Data mining method is applied to analyze the commonly used meridians, acupoints and special acupoints in different dynasties, also possible rules are explored. Totally 82 pieces of prescription of acupuncture-moxibustion for treatment of vertigo are included. In the history the leading selection of acupoitns are Fengchi (GB 20), Hegu (LI 4), Shangxing (GV 23) and Jiexi (ST 41) while that of meridians are mainly three yang meridians of foot and the Governor Vessel, especially the acupoints on the Bladder Meridian of foot yangming had the highest utilization rate, accounting for 23.04%. The acupoint selection is characterized by special acupoint, accounting for 80.6%, among which the crossing points are the most common choice. Distal-proximal acupoints combination is the most frequent method. The results indicate that the ancient acupuncture-moxibustion for treatment of vertigo focused on acupoints in the yang meridians, and the specific acupoints play an essential role in prescription; also the principle of syndrome differentiation and selecting acupoints along the meridians could be seen.

Objective Despite regular treatment,antineutrophil eytoplasmie antibodies(ANCA)asso- ciated systemic vasculitis(AASV),in which the role of Fc?Rs has been established,are still associated with significant long-term mortality and remain an important cause of end-stage renal failure.ANCA plays an im- portant role in the pathogenisis of primary systemic small vessel vasculitis(PSV)by their potential to activate neutrophils.Because the interaction between ANCA and its receptors on the Fc portion of immunoglobulins (Fc?R)on neutrophils is essential in the activation process,we investigate the inhibitory,effect of tg19320 on ANCA induced activation of neutrophils,which is a tetrameric tripeptide that interferes with IgG/Fe?Rs in- teraction.Methods We prepared tg19320 by solid-phase peptide syntbesis.The binding between tg19320 and human IgG was assessed by enzyme-linked immunosorbent assay.The biological activity of tg19320 to intefere with FcF?receptor recognition was identified by rosette formation assay.ANCA IgG was prepared from the sera of active Wegener's granulomatosis(WG)and microscopic polyangiitis(MPA)patients.Neu- trophils isolated from the blood of healthy volunteers were primed with TNF-?(2 ng/ml)and then incubated with ANCA IgG(200?g/ml),or pretreated with tg19320(2.5 mg/ml)and then added with ANCA IgG.Su- peroxide burst of neutrophils was determined by Ferri-cytochrome reduction assay.Results We found that tg19320 bound tightly to human IgG in a dose dependent manner and the inhibition of the rosette formation between SRBC-IgG and U937 cells was statistically significant(20.3% vs 53.2%,P
