Objective To study the value of interventional therapy for chest diseases via internal mammary artery (IMA) and the features of internal mammary artery angiography. Methods 31 cases of different chest diseases were undertaken the angiography and interventional therapy through IMA. Results The lesions of 31 cases were supplied by internal mammary artery partly or totally. The good therapeutic effectiveness was achieved in 20 cases with pulmonary carcinoma. The masses and the enlarged lymph nodes were shrinked obviously in 4 cases of advanced breast carcinoma and one of them was cured with operation after internal mammary arterial infusion. One case of low invasive thymoma was cured by internal mammary arterial infusion combined with resection. The bleeding was stopped absolutely after IMA embolization in 6 cases of hemoptysis (bronchiectasis in 2 cases, pulmonary tuberculosis in 4 cases). Conclusions The interventional therapy via IMA is very important and necessary when the mass in the chest is supplied by IMA.

Objective To investigate the efficacy of acupoint selection at distant places and local tenderness points in treating migraine without aura.Method Sixty patients were randomly allocated, using a random number table, to two groups, 30 cases each. The treatment group received acupuncture at distant points selected along meridians and local tenderness points and the control group, acupuncture at conventionally selected points. The therapeutic effects were evaluated using the visual analogue scale (VAS) and the short-form McGill Pain Questionnaire (SF-MPQ).Result After treatment, the VAS pain score was lower in the treatment group than in the control group; there was a statistically significant difference (P<0.05). The total efficacy rate was 93.3% in the treatment group and 73.3% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Both acupuncture at distant points selected along meridians and local tenderness points and acupuncture at conventionally selected points have a certain therapeutic effect on migraine, but the former produces a better effect than the later and can markedly relieve the pain and improve the quality of life in the patients. The outcome of this study provides a certain reference value for clinical treatment of this disease.

Objective To investigate the surgical techniques and clinical effects of anterior retropharyngeal approach in treatment of C2/3 fracture and dislocation.Methods Twelve patients with C2/3 fracture and dislocation treated via anterior retropharyngeal approach between November 2011 and April 2013 were included in the study.There were 7 males and 5 females aged from 19 to 65 years (mean,35 years).Primary pathologies included 7 patients with traumatic C3 fracture,2 with Hangman fracture and 3 with fracture and dislocation of the anteroinferior margin of C2 vertebrae.C2-C4 vertebrae were exposed using anterior retropharyngeal approach,followed by C2/3 discectomy or C3 corpectomy,decompression,interbody cage fusion or titanium mesh cage fusion,and anterior internal fixation.Results Exposure of lesion was sufficient for all patients and all operations were completed under direct vision,with mean operation time of 140 minutes and mean blood loss of 120 ml.One patient with reduced tone after operation gradually recovered in a week; one with dysphagia after operation recovered in 3 months; one with skin necrosis 7 days after operation was recovered by changing dressing; for the rest,there were no complications of incision hematoma,infection,or asphyxia.Ten patients were followed up for mean 15 months,which showed bony fusion in mean 6 months.At final follow-up,no implant loosening or displacement occurred.Conclusion Anterior retropharyngeal approach to C2/3 fracture and dislocation provides sufficient exposure of lesions,minor trauma,and less bleedings and complications,but as the local anatomy is complicated,there indeed exists a learning curve of the approach.

Objective To induce the immunoincompetence of T cells to oxidized-low density lipoprotein(ox-LDL)in vitro,in order to prevent immune injuries in atherosclerosis(AS)and to find new strategies to prevent AS.Methods Monocytes were separated from peripheral blood to induce dendritic cells (DC).DCs were treated with LPS(30 ng/m1),ox-LDL(10μg/m1)and LDL(10μg/m1)for 48 h,respectively.Then DCs were mixed with allogeneic T lymphocytes to earry out mixed lymphoeytes reaction (MLR).CTLA4Ig in different concentrations was added into the MLR of ox-LDL group.MTr method was used to assay the proliferation of T cells.The CD25 expression and apoptosis of T cells in MLR were tested by flow cytometry.And the excretion of IL-2,IFN-γ and IL-4 were assayed by ELISPOT method.Results SI of the ox-LDL group was higher than that of the LDL group significantly(DC:T=1:5,1.6717±0.3152vs 1.4250±0.2874.P<0.05;DC:T=1:10,1.5458±0.2748 vs 1.3352±0.2991,P<0.05),and CTLA4Ig inhibited the SI of the ox-LDL group in dose-dependence(CTLA4Ig 1.25μg/ml,0.96±0.30 vs μg/ml 1.29±0.28 vs 1.64±0.33 P<0.05).CTLA4Ig caused the decrease of CD25 expression(CTLA4Ig 1.25 μg/ml,11.26±0.58 vs 14.25±1.02,P<0.05;CTLA4Ig 10μg/rnl 8.42±0.45,P<0.01)and induced apoptosis of T cells in MLR(CTLA4Ig 1.25μg/ml,12.54±3.69 vs 6.09 4-2.24,P<0.05;CTLA4Ig 10μg/ml,26.87±5.06 VS 6.09±2.24,P<0.01).CTLA4Ig caused the decrease of ELISPOT counts of IL-2(CTLA4Ig 1.25μg/ml,386±42 VS 534±54,P<0.05;CTLA4Ig 10μg/rnl,230±27 VS 534±54,P<0.01)and IFN-γ(CTLA4Ig 1.25μg/ml,445±48 VS 672±46,P<0.05;CTLA4Ig 10μg/ml,193±39 VS 672±46,P<0.01),while that of IL-4 increased(CTLA4Ig 1.25μg/ml,401±32 VS 332±41,P<0.05;CTLA4Ig 10μg/ml,453±57 VS 332±41,P<0.05).Conclusion CTLA4Ig can induce T cens immunoin competence to ox-LDL in vitro by inhibiting T cells activation,inducing T cells apoptosis and TH 1/TH2 immune deviation.

Objective: To explore the role of human hematopoietic growth factors (HGFs) in proliferation and differentiation of cord blood CD34+ cells. Methods: Human cord blood mononuclear cells (MNC) were cultured with different combinations of HGFs (including rhIL-1,rhIL-3, rhIL-6, rhG-CSF, rhGM-CSF and rhSCF). The expansion folds of MNC, the changes of cellular surface markers by FACS, and CFU-GM of hematopoietic cells were observed. Results: The total nucleated cells expanded by 44 folds after cultured with 6 cytokines for 20 days. The number of CFU-GM increased by 14 .74 folds after cultured in liquid for 8 days, but decreased heavily after 18 days. The total number of CD34+ cells increased by 127. 79 ~ 196 .40 folds at 6 to 8 day, but decreased to 101.51 folds at 18 day. Conclusion: Human hematopoietic growth factors can increase the expansion of cord blood CD34+ cells and CFU-GM significantly.

Objective To investigate the clinical significance of anti-nuclear envelope protein antibody (gp210),anti-soluble acid resistant nucleoprotein (sp100) and anti-mitochondrial antibody M2 subtype (AMA-M2) in sjogren syndrome (SS) and primary biliary cirrhosis (PBC).Methods A total of 241 hospitalized patients diagnosed with connective tissue disease (CTD) were recruited.Anti-gp210,anti-sp100 and AMA-M2 were detected by indirect immunofluorescence.Results (1) Positive rate of AMA-M2,anti-sp100 and antigp210 in 241 cases CTD patient were 10.4％ (25/241),3.3％ (8/241) and 2.9％ (7/241) respectively.(2) There were 16 cases with SS,5 cases with SS-PBC overlap syndrome and 17 cases with PBC in 241 patients with CTD.Distinction among groups of PBC,SS,SS overlapping PBC of positive incidence of AMA-M2 antibody (x2 =6.584,P =0.03) and anti-gp210 (x2 =8.735,P ＜ 0.01) were significantly different,while there was no apparent difference about positive rate of anti-sp100 among the three groups (x2 =3.343,P =0.18).(3) Positive expression of either antibody of anti-gp210 or anti-sp100 in the three groups of SS,SS overlapping PBC,PBC were 3 cases,4 cases,4 cases respectively.The positive rates of any of three autoantibodies in three groups of were 8 cases,5 cases,13 cases respectively.(4) There were significant difference in terms of serum ALB(t =3.858,P＜0.000 1),TSB(t =5.473,P＜0.000 1),ALT(t =2.235,P=0.026),AKP(t =3.141,P =0.002) and γ-GT (t =2.317,P =0.021) in liver damaged patients of all CTD between AMA-M2 positive and negative patients (P ＜ 0.05).However,serum TSB in anti-sp100 positive and negative patients were differed (t =7.892,P ＜ 0.000 1).Serum AKP was different between anti-gp210 positive and negative patients (t =2.451,P =0.015).Conclusion Positive rate of anti-gp210,anti-sp100 and AMA-M2 are the highest in patients with SS overlap of the PBC among CTD patients.Combined detection can improve the sensitivity of diagnosis.Antisp100 and anti-gp210 are valuable for the diagnosis of SS-PBC overlaps syndrome with negative AMA-M2.

Objective To evaluate the anti-proliferation and anti-angiogenesis effect of curcumin-K30 solid dispersion (Cur-K30) on tumors in vivo. Methods Growth inhibition rates of the tumor cells was measured with MTT method. Tumor inhibition was detected by tumors transplanted subcutaneously in mice treated with Cur-K30 ［50， 100， and 200 mg/(kg·d)］. The expressions of CD34 and vascular endothelial growth factor (VEGF) were assessed by immunohistochemical study, and analyzed by Imageproplus software. Results Cur-K30 had inhibitory effect on different tumor cell lines in a dose dependent manner with IC50 values from 6.6 to 12.12 μg/mL. The in vivo study showed that the inhibitory rates of the 200 mg/(kg·d) Cur-K30 group on H22, B16, and SW480 were 43.2%, 53.1%, and 59.8%, respectively, which were all much higher than the inhibitory rates of curcumin suspension group with the same dose. Compared with the control group， the expression of CD34 and VEGF in SW480 tumors was down-regulated in the 200 mg/(kg·d) Cur-K30 group (P<0.01). Conclusion The proliferation inhibition of Cur-K30 is higher than curcumin in vivo， and the most significant effect is obtained in SW480 tumors transplanted subcutaneously in nude mice. Down-regulation of VEGF and decreased microvascular density may contribute to the anti-tumor effect of Cur-K30.
