[Objective] To investigate the relationship between the body constitution and the syndromes of the bronchiectasis patients and provide the basis for the clinical treatment.[Methods] Col ected 80 out-patients and in-patients of bronchiectasis in the first affiliated hospital of Zhejiang Chinese Medical University from May 2011 to March 2012. Al patients met with the inclusion criteria, adopted the standardization of physical scale for physical identifica-tion and dialectical type and analyzed the relationship between constitution and syndrome.[Results] ①The gentleness type, qi-deficiency type and yin-defi-ciency type were more popular in the bronchiectasis, fol owed by the phlegm-wet type, wetness-heat type, yang-deficiency type and qi-depression type. The special inherited type and blood-stasis type were very rare. ②The syndrome of phlegm heat obstructing lung was the top one in the Chinese tradi-tional medical syndromes(48.75%).The frequency of liver-fire attacking lung syndrome, hyperactivity of fire due to yin deficiency syndrome and qi-yin de-ficiency syndrome were 21.25%, 18.75% and 11.25% respectively. ③From different body constitution distribution of TCM syndromes in patients with bronchiectasis, it could be found:gentleness type, qi-deficiency type, yang-deficiency type, phlegm-wet type and wetness-heat type were most presented as phlegm-heat stasis lung syndrome. Patients with qi-deficiency type were most presented as qi-yin deficiency syndrome .Patients with Yin deficiency type were always performed as hyperactivity of fire due to yin-deficiency syndrome. Patients with lung qi-stasis type were liver-fire invading lung syn-drome.[Conclusion] Phlegm-heat stasis syndrome was the main syndrome in patients with bronchiectasis. It conformed to the pathological characteristics of deficiency essence with virtual reality. Different body constitutions decided the different traditional Chinese medical syndromes after the disease onset.

Methods Thirty one cases of maloclusion (subclass Ⅰ of the class Ⅱ) were selected,in which all the mandible were in a backward position revealed by clinical examination and roentgenographic cephalometry.Functional appliance was used to put forward the mandible,and then the changes of IMPA, Z angle, H angle, soft tissue profile angle, upper lip E Line, lower lip E Line, upper lip/lower lip, and lower facial height were compared before and after treatment. Results All of the cases showed up a better improvement of the profile after the functional appliance therapy. Z angle, H angle, soft tissue profile angle, upper Lip E line, upper Lip/lower lip, lower facial height became normal or close to normal.There was a statistical significantce in the changes ( P

Objective To investigate the imaging features of Budd-Chiari syndrome(BCS) on 64 slice spiral computed tomography(64SCT) and the diagnostic value of 64SCT for BCS.Methods Twenty-nine patients diagnosed as BCS by 64SCT were retrospectively included into this study and all the patients were researched by digital substraction angiography(DSA).Two abdominal radiologists analyzed the CT imaging features of BCS,paying attention to the vascular lesion,the morphology abnormality of the liver and the degree of portal hypertension,with review of DSA findings.Results ①The accuracy of 64SCT for BCS was 93.1%(27/29),and there were 2 false positive cases and no false negative case.The accuracy of 64SCT for those patients with thrombosis of inferior vena cava(IVC) and(or) hepatic vein(HV) was high as compared to those with stenosis of IVC and(or) HV.②The morphology abnormality of the liver included hepatomegaly(24 cases),low attenuation(27 cases) and inhomogeneous pattern of parenchymal contrast enhancement(5 patients in arterial phase and 19 patients in portal vein phase).③The images of all the patients showed the features of portal hypertension.Conclusion The accuracy of 64SCT for BCS is satisfactory and the false negative is seldom.The 64SCT could accurately display the morphology abnormality of the liver and the compensatory circulation in BCS patients.For those patients with stenosis of IVC and(or) HV,however,the diagnostic power of 64SCT is limited.

Objective:To develop an HPLC method for determining the total ginkgo flavonoid in self-emulsifying drug delivery sys-tem. Methods:Effective chromatographic separation was achieved using a phenomenex C18 column (250 mm × 4. 6 mm, 5 μm) with a mobile phase composed of methanol and water (0.4% phosphoric acid) with the ratio of 50 ∶50 (v/v). The mobile phase was pumped using an isocratic HPLC system at a flow rate of 1. 0 ml·min-1 , the detection wavelength was 360 nm and the column temper-ature was 30 ℃. Results:The three components in the total ginkgo flavonoid were well separated by the proposed method. The linear relationship between the peak area and the concentration was promising within the range of 2. 0-40. 0 μg·ml-1 for quercetin, 3. 0-60. 0 μg·ml-1 for kaempferide and 2. 0-40. 0 μg·ml-1 for isorhamnetin. The mean recovery of quercetin, kaempferide and isorham-netin was 98. 4%, 99. 7% and 100. 5% with RSD of 0. 92%,0. 62% and 1. 24% (n=9), respectively. Conclusion:The method is specific and stable in the determination of total ginkgo flavonoid in self-emulsifying drug delivery system.

Objective:To prepare total ginkgo flavonoid self-emulsifying drug delivery system(TGF-SMDDS)and estimate its char-acteristics in vitro. Methods:The formula of TGF-SMDDS was optimized based on the solubility tests,formula compatibility and microe-mulsion area in the pseudo ternary phase diagram. The appearance,morphology,particle size,zeta potential and in vitro dissolution of TGF-SMDDS were investigated. Results:The formula was composed of oleoyl macrogolglycerides as the oil phase,Tween-80 as the sur-factant and XCF as the co-surfactant. The ratio of oil phase,surfactant and co-surfactant was 10 ∶ 6 ∶ 4. The drug loading was 10. 0 mg· g -1 . After mixed with water,TGF-SMDDS was formed a clear and transparent microemulsion with homogeneous small spheres as seen un-der a transmission electron microscope. The particle size and zeta potential of TGF-SMDDS was(87. 4 ±26. 7)nm and( -13. 1 ±1. 5) mV,respectively. The accumulative dissolution of TGF-SMDDS in pH1. 2 hydrochloric acid solution was(96. 1 ±4. 8)% in 45 min. Con-clusion:The TGF-SMDDS can significantly enhance the dissolution of TGF in vitro,which may be a potential effective preparation for TGF.

Objective To evaluate the effects of tumor-associated macrophages on the proliferation,invasion and migration of human cutaneous malignant melanoma cells.Methods Cultured U937 human monocytic cells at logarithmic phase were classified into three groups to be pretreated with phorbol ester for 48 hours followed by 48-hour activation by phorbol ester (M polarization),lipopolysaccharide (LPS) at 25 mg/L (M1 polarization),and interleukin (IL)-4 at 15 μg/L (M2 polarization) respectively.Then,enzyme-linked immunosorbent assay (ELISA) was performed to determine the levels of IL-12p70 and IL-10 in the supernatant of these activated cells.A375 human malignant melanoma cells were divided into four groups to be cultured alone or with M-,M1-and M2-polarized macrophages respectively.After additional culture for different durations (24,48 and 72 hours),methyl thiazolyl tetrazolium (MTT) assay was conducted to estimate the proliferative activity,and Transwell assay to evaluate the invasion and migration activity,of the A375 cells.Results The proliferation of A375 cells was accelerated by coculture with M-and M2-polarized macrophages,but inhibited by that with M1-polarized macrophages,with significant differences among the four groups in the proliferative activity at 48 and 72 hours (all P ＜ 0.05),but not at 24 hours (P ＞ 0.05).Invasion assay showed that the number of A375 cells that migrated through Transwell chambers was significantly larger in M2 and M groups (147.00 ± 7.92 and 113.22 ± 8.15 respectively),but smaller in the M1 group (56.44 ± 7.55),than in the control group (84.11 ± 6.07,all P ＜ 0.05).Similarly,migration assay revealed a significant increase in the number of A375 cells that migrated through Transwell chambers in the M2 and M(p) groups (198.33 ± 8.22 and 156.00 ± 8.83 respectively),but a significant decrease in the M1 group (97.11 ± 6.75) as compared with the control group (123.89 ± 7.01,all P＜ 0.05).Conclusions The proliferation,invasion and migration of A375 cells can be accelerated by IL-4-activated M2-polarized macrophages,but decelerated by LPS-activated M1-polarized macrophages.Phorbol ester tends to induce monocytic cells to differentiate into M2-polarized macrophages.

objective:To investigate the clinical features and prognosis of pinealoblastoma in children. Methods:The clinical data of 10 patients with pinealoblastoma were retrospectively analyzed. These patients were admitted to the Department of Radiation Oncology, Beijing Shijitan Hospital, Capital Medical University from December 2011 to December 2015. Results:This study included 10 patients, with 8 males and 2 females, with a median age of 7 years. Of the 10 patients, 5 underwent gross total resection and 5 underwent sub-total resection. The 10 patients were exposed to craniospinal irradiation after surgery. The median doses of craniospinal irradiation and tumor bed were 30.6 (25.5-36) Gy and 55.8 (50.4-60) Gy, respectively. Of the 10 patients, 4 underwent chemotherapy 1 month af-ter radiotherapy. The median follow-up period was 16.5 (1.5-49) months. The 10 patients survived. No local and distant recurrences were observed. Conclusion:Pinealoblastomas are rare, malignant, and pineal regional lesions that can metastasize along the neuroax-is. Surgery combined with adjuvant radiotherapy and chemotherapy should be applied to patients with pinealoblastoma. Prognosis is also favorable.

Idiopathic pulmonary fibrosis ( IPF) is a kind of Interstitial lung disease with cause unknown,which is aggressive for its increasing prevalence and high morbidity and mortality.At present the pathogenesis of IPF is not entirely clear, but cells and cel-lular interactions play a decisive role on the alveolar inflammation and fibrosis results.We review IPF related cells of interest ( immune competent cells and fibroblast, fibrocyte, myofibroblast, endothelial and alveolar epithelial cells) , to summarize cells and cellular in-teractions in the pathogenesis of IPF,and discuss new research directions and therapeutic targets.

Objective To evaluate the hematological toxicity of craniospinal irradiation,and determine the short-term clinical efficacy and prognostic factors in medulloblastoma.Methods Eightseven patients who underwent craniospinal irradiation were retrospectively analyzed with respect to the changes in hematology during craniospinal irradiation.The effect of sex,age,tumor location,interval between surgery and radiation,interval time during radiation and radiation sequence on survival were also studied.Results The 1,2,3-year overall survival (OS) and progress-free survival (PFS) rate were 95.0％,92.4％,84.9％ and 93.7％,89.8％,80.8％,respectively.The incidence of 2-3 grade leucopenia was 90.8％,while the incidence of 1-2 grade thrombocytopenia was 70.1％,and the incidence of 3 grade thrombocytopenia was 1.1％.The incidence of 1-2 grade hemoglobin reduction was 16.1％.No patient had grade 3-4 hemoglobin reduction.Kaplan-Meier analysis shows that more favorable prognoses in terms of 3-year PFS were evident for 0-1 grade thrombocytopenia compared with 2-4 grade thrombocytopenia (x2 =3.936,P ＜ 0.05).And 3-year PFS and 3-year OS were evident for 0 grade hemoglobin reduction compared with 1-4 grade hemoglobin reduction (x2 =10.269,9.336,P ＜ 0.05).The 3-year PFS between interval time during radiation ＜ 3 days and ≥ 3 days was 84.6％ and 68.6％ (x2 =4.413,P ＜ 0.05).Conclusions Hematological toxicity during craniospinal irradiation and the interval time during radiation were prognostic factors.
