OBJECTIVETo prepare and identify a polyclonal antibody (pAb) against (mouse) cysteinyl leukotriene receptor 1 (CysLT(1)) and to investigate the changes of CysLT(1) receptor expression in BV2 microglial cells after rotenone treatment.

METHODSRabbits were immunized with KLH-coupled CysLT(1) peptide to prepare the pAb. The titer of the pAb in rabbit plasma was detected by ELISA method, and the specificity of the pAb was tested by antigen blockade. After BV2 cells were treated with rotenone (0.01-1 μmol/L) for 24 h, the expression of CysLT(1) was determined by immunostaining, Western blotting and RT-PCR.

RESULTThe pAb showed a titer of 1/32728, and was not cross-reacted with antigens of CysLT(2) receptor and GPR17. Immunostaining, Western blotting and RT-PCR analysis showed the expression of CysLT(1) receptor in BV2 microglia. Rotenone at 1μmol/L significantly induced an increased expression of CysLT(1) receptor.

CONCLUSIONThe prepared CysLT(1) receptor polyclonal antibody has a high titer and high specificity to meet testing requirements of Western blotting and immunostaining; CysLT(1) is associated with rotenone-induced injury of BV2 microglial cells.

OBJECTIVETo investigate the application and significance of aerodynamic parameters in voice function assessment.

METHODSThe phonatory aerodynamic system (PAS) was used to collect aerodynamic parameters from subjects with normal voice, vocal fold polyp, vocal fold cyst, and vocal fold immobility. Multivariate statistical analysis was used to compare measurements across groups.

RESULTSPhonation threshold flow (PTF), mean flow rate (MFR), maximum phonation time (MPT), and glottal resistance (GR) in one hundred normal subjects were significantly affected by sex (P < 0.05), while phonation threshold pressure (PTP), subglottal pressure (SGP), and vocal efficiency (VE) were not (P > 0.05). PTP, PTF, MFR, SGP, and MPT were significantly different between normal voice and voice disorders (P < 0.01), and there were no significant differences among the three disorders (P > 0.05). Receiver operating characteristic (ROC) analysis found that PTP, PTF, SGP, MFR, MPT, and VE in one hundred thirteen voice dis orders had similar diagnostic utility (P < 0.01), with PTP exhibiting the highest area under the curve. The aerodynamic parameters of the three degrees of voice dysfunction due to vocal cord polyps were compared and found to have no significant differences (P > 0.05). PTP, PTF, MFR, SGP and MPT in forty one patients with vocal polyps were significantly different after surgical resection of vocal cord polyps (P < 0.01).

CONCLUSIONThe aerodynamic parameters can objectively and effectively evaluate the variations of vocal function, and have good auxiliary diagnostic value.

OBJECTIVETo assess the effects of ambient air pollutants on hospital outpatient visits for allergic disease and pollinosis.

METHODSThe monitoring data of daily air pollution (SO(2), NO(2) and PM(10)) in 8 national monitoring and controlling sites of Beijing air quality, airborne pollen in 4 monitoring sites of Beijing, and daily meteorological data, along with the daily numbers of outpatients visits for allergic disease and pollinosis at the Allergy Department of Beijing Shijitan Hospital from April to September in 2004 were collected. Associations between the levels of air pollutants and outpatient visits for allergic disease and pollinosis were estimated by time serial analysis using a generalized addictive model (GAM), considering lag effect and the influence of multipollutants.

RESULTSDuring the study period, the average daily ambient concentrations of SO(2), NO(2) and PM(10) were (20.9 ± 12.9), (58.6 ± 13.6) and (126.8 ± 64.1) µg/m(3), respectively. The mean daily pollen count was (163.8 ± 209.0) grains/1000 mm(2), while the average daily numbers of doctor visits for allergic disease and pollinosis were (16.3 ± 5.3) and (3.5 ± 5.0), respectively. Time serial analysis showed that significant positive associations were found between levels of airborne pollen and doctor visits, with an excess risk (ER) of 2.44% (95%CI: 0.75% - 4.13%)for allergic disease and 6.58% (95%CI: 3.82% - 9.34%) for pollinosis per 100 grains/1000 mm(2) increase in pollen, in single-pollutant models. There were associations between ambient air pollutants (SO(2), NO(2), PM(10)) and doctor visits with lag effects. A 10 µg/m(3) increase in NO(2) was associated with a 3.14% (95%CI: 0.42% - 5.85%) increase in doctor visits for allergic disease at lag 6 d. For pollinosis, the highest ER was observed for 10 µg/m(3) increases in SO(2) at lag 1 d, NO(2) at lag 6 d, PM(10) at lag 3 d. However, this association was not statistically significant (RR (95%CI) were 1.0460 (0.9640 - 1.1280), 1.0325 (0.9633 - 1.1017), 1.0079 (0.9942 - 1.0217), respectively). The associations enhanced slightly in multi-pollutant models with an ER of 2.56% (95%CI: 0.80% - 4.31%) for allergic disease and 6.81% (95%CI: 3.91% - 9.71%) for pollinosis per 100 grains/1000 mm(2) of pollen.

CONCLUSIONSOur results suggest that level of airborne pollen may have a stronger effect than ambient air pollutants on allergic disease and pollinosis.

The plaque-forming characteristics of Newcastle disease viruses of chickens and geese source were compared on various cells. The result showed that there were obvious differences of plaque formation between F48E9 and NA-1 on Vero cells, chicken embryo fibroblast cells (CEF) and goose embryo fibroblast cells (GEF). The plaque-forming ability of NA-1 was higher than F48E9 on GEF, but lower than F48E9 on CEF. On Vero cells, the plaque-forming ability of NA-1 was slightly stronger than F48E9. It demonstrated that the plaque-forming characteristics were consistent with host tropism of virus. The morphogenesis of F48E9 and NA-1 on Vero cells was observed with transmission electron microscope. There were different replication processes between F48E9 and NA-1 on cells at different stages. NA-1 had stronger adaptability to host than F48E9 according to budding processes and envelope integrity.

OBJECTIVETo evaluate the diagnostic value and safety of flexible bronchoscopy in congenital great vessel diseases complicated with airway compression.

METHODThe medical records of patients with great vessels abnormalities who were admitted to the neonatal intensive care unit (NICU) from October 2005 to June 2009 were retrospectively reviewed; 34 cases were diagnosed as airway compression by flexible bronchoscopy, 10 cases as vascular ring, 24 cases as aortal arch obstruction. The age of the patients was 6 d - 11 m, body weight 2.2 - 8.7 kg [(4.6 +/- 1.4) kg]. Recorded airway abnormalities detected by bronchoscopy and CT, cardiac vascular defects and airway compression were consistent with the findings on operation. The relation between the airway compression and cardiac vascular abnormalities, treatment of the airway compression and outcome were analysed.

RESULTBronchoscopic assessment was successfully performed in NICU or operating room for all the patients. (1) Initial presentation of the 34 cases were tachypnea, stridor, refractory lung infection and prolonged mechanical ventilation. (2) Extrinsic compression was found in all the 10 cases with vascular ring by bronchoscopy initially which indicated vascular ring, airway compression was mainly of lower part of trachea. Diagnosis of 9 cases was consistent with CT diagnosis and in 1 case the diagnosis was confirmed by surgery; among these cases, 7 had congenital tracheal stenosis. (3) In the 24 cases with aortic obstructive lesion, 5 were detected to have tracheal stenosis by CT before correction of vascular abnormality, among whom one case was indicated to have tracheal stenosis by bronchoscopy, the other 19 cases were found with airway compression by bronchoscopy during or after vascular correction. Among the 24 cases, 21 had left main bronchial stenosis, 2 had congenital tracheal stenosis. Airway compression diagnosed by bronchoscopy agreed with the findings of CT. Two cases developed transient decrease of oxygen saturation, 5 cases developed transient tachycardia.

CONCLUSIONFlexible bronchoscopy plays an important role in assessment of the airway compression complicated with great vessel abnormalities. Bronchoscopy is an accurate, convenient, safe and rapid way for airway assessment, but further examination of the peripheral structure and vascular malformation need combined examination with CT.

OBJECTIVETo investigate the application of penile cavernous bodies elongation combined with fat flap for the treatment of micro-penis.

METHODSAnatomic study was performed to study the thickness of penile suspension ligaments and the relationship between the penile erection stability and the mobilization of cavernous bodies crus. The suspension ligaments were divided and cavernous bodies crus were partially mobilized, so as to release part of the cavernous bodies from inferior ramus of pubis. Then the penis was elongated sufficiently. Local fat flap was transposed to fill the front space of pubis to make sure the effective elongation of penis.

RESULTS205 cases of micro-penis were treated. The average length of the penis was 4.26 cm in the static state, 8.13 cm in erectile state before operation. After operation, it increased to 8.63 cm in the static state, 12.11 cm in erectile state.

CONCLUSIONSThe cavernous bodies can be elongated 1-2 cm more with the modified method, while the stability of penile erection is not affected.

OBJECTIVETo investigate the clinicopathological characteristics and prognosis in breast cancer with brain metastasis (BCBM).

METHODSThe clinical data of 137 BCBM from June 2002 to June 2008 was reviewed and analyzed. Their molecular subtypes were categorized based on detection of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2) expression. The focal area included 35 cases of triple-negative breast cancer (TNBC), 38 cases of HR (ER and PR) (-)/HER-2(+), 40 cases of HR(+)/HER-2(-), 24 cases of HR(+)/HER-2(+). The clinical characteristics and the outcome in patients with influence were analyzed.

RESULTSIn 137 BCBM, the median overal survival after brain metastasis was 6.5 month. The median survivals of TNBC, HR(-)/HER-2(+), HR(+)/HER-2(-) and HR(+)/HER-2(+) were 5.0, 5.5, 10.0 and 9.5 months, respectively. The median survivals after brain metastasis of the breast cancer patients who received the combination therapy of whole brain radiation therapy (WBRT) and neurosurgery and/or stereotactic radiosurgery, received WBRT but not combination therapy and didn't receive WBRT were 15.0, 9.5 and 4.0 months, respectively. In univariate survival analysis, substyle, number of brain metastasis, brain metastasis as initial recurrence or not, brain-only metastases or not, the combination therapy status after brain metastasis were obviously correlated with the prognosis (χ(2) = 6.891 to 29.414, P < 0.05). Substyle (RR = 1.234, 95%CI: 1.057 to 1.440) and the combination therapy status after brain metastasis (RR = 1.838, 95%CI: 1.389 to 2.431) were independent prognostic factor in multivariable analysis (P < 0.05).

CONCLUSIONSTNBC confers a high risk of death after brain metastases. Systemic treatment via combined modalities are helpful for breast cancer patients, even after the detection of brain metastases.

OBJECTIVESTo explore the diagnostic value of color Doppler flow imaging (CDFI) in monitoring portal vein complications (PVC) following orthotopic liver transplantation (OLT).

METHODSFive hundred and four patients received OLT and had CDFI examinations before and after their transplantations. CDFI monitoring parameters before the operation included portal vein diameter, blood flow velocity and the presence of thrombi within the portal vein. Monitoring parameters after the operation included portal vein diameters of donor and receiver sides, and the diameter of the mouth of anastomosis, inner side of blood vessel echo, the direction of blood flow and its speed.

RESULTSOf the 504 patients examined, the median velocity of the portal blood flow was 46.27 cm/s (range: 15.8 to 110.8) on the day of the operation. The blood flow speed of 358 cases (71.03%) was higher than 40 cm/s. Of the 358 patients, 347 (68.85%) had a blood flow speed lower than 40 cm/s one month after the operation. Sixty-four patients (12.70%) showed hepatofugal blood flow once, and only one case had a total hepatofugal blood flow. Thirteen patients (2.58%) had portal vein complications, including 4 cases with portal vein thrombosis and 9 with portal vein stenosis.

CONCLUSIONNot all abnormal portal vein blood flow signals will lead to complications. It is worthwhile to monitor the portal blood flows. CDFI plays an important role in the diagnosis of portal vein complications after orthotopic liver transplantation.
