Objective To investigate the mechanisms of attachment of respiratory syncytial virus(RSV) to human airway epithelial cells.Methods Attachment of RSV to CFBE was quantitatively assessed by flow cytometry.Various polyclonal and monoclonal antibodies to RSV and heparin were pre-incubated with RSV.The blocking effects of these antibodies and heparin on attachment were evaluated.Results CFBE cells reduced capacity being bound by RSV.All the antibodies used were failed to block attachment of RSV on CFBE,whereas heparin blocked RSV attachment in a dose-response manner and the blokade by heparin was almost complete at the concentration of 0.4 mg/L.Conclusions Flow cytometry provides direct evaluation of attachment without growth of virus.Heparin-like molecules on cell surface of CFBE appears to be involved in attachment between RSV and human epithelial cells.

Objective To evaluate the clinical efficiency of partial splenic embolization on portal hypertension patients of hepatocellulocarcinoma(HCC).Methods 110 patients of hepatocellulocarcinoma with portohypertension were treated with 1-3 times of TACE, and partial splenic embolization, with PVA of 355~500 ?m injecting into the arteries of inferior splenic pole. In order to control the area of splenic embolization, multi-embolizations were done according to the various conditions. Results 172 times of embolization were performed in 110 patients involving 134 times of fever lasting for 3-30 days and 126 times of bellyache with 27 times appealing for morphine. Treatable hydrothorax appeared in six, and no serious complications occurred. The area of embolization covered 30%~60%. WBC and BPC counts were increased after the 24 hour (P

Objective To discuss the clinical value of preoperative embolization of vertebral tumors. Methods Data of 54 patients were retrospectively studied. Thirteen lesions were in the cervical, 17 in the thoracic, 15 in the lumber and 9 in the sacral regions. The vertebral tumors were embolized prior to operation with gelatin sponge particles, polyvinyl alcohol (PVA) particles or coils. Surgical operations were performed within 1-7 days after the embolization. Results Totally 79 vessels of 43 patients were embolized, which included ascending cervical artery,1;vertebral artery,1;intercostal artery,39; lumber artery,19;internal iliac artery,15 and median sacral artery,4. Intraoperative hemorrhage showed a mean value of 1312 ml with range of 300-3000 ml in patients after embolization, and a mean value of 2375 ml with range of 1500-5000ml in patients without embolization at the same period(P

Objective To analyze the treatment of transplant renal artery stenosis (TRAS) by percutaneous transluminal angioplasty (PTA) and stenting. Methods The average time duration from transplantation to the on set symptom of TRAS was 6.9 months (3 - 18 months) in 35 TRAS patients. BP and creatinine level were recorded before and after the procedure. PTA was performed through contralateral femoral or left brachial approach with ordinary balloon (5 F, length 20 ~ 30 mm) and / or small balloon catheters (2. 6 F, length 36 mm) in all patients, and stents were embedded in 11 of them. Results A total of 46 PTA were successfully performed (1 time, 20 cases; 2 times, 12 cases, and 3 times, 3 cases) via contralateral femoral approach (26) and left brachial approach (15). Stenosis were significantly decreased from 75% ~ 98% pre-PTA to 10% ~ 30% post-PTA.Systolic pressure decreased from 170 mmHg (150 ~ 210 mmHg) pre-PTA to 135 mmHg (100 - 190 mmHg) post-PTA and diastolic pressure decreased from 120 mmHg (90 - 145 mmHg) to 85 mmHg (80 - 125 mmHg) respectively. Restenosis rates were 39% after first PTA and 15% after the second time. All 46 times of PTA used 26 ordinary balloon catheters and 20 microballoon catheters. 8 self-expandable stents (Wallstent) and 3 balloon-dilatation stents (Palmaz) were released in 11 cases. There were healed case (n = 11) , melioration (n = 15), improvement (n = 7), and inefficiency (n = 2) after follow - up of 23 months (3 - 60 month). No complication occured except puncture site hematoma via the brachial artery approach in 1 case. Conclusions PTA is safe and effective in the treatment of TRAS and high rate of procedure success may be achieved with the help of brachial approach and micro-balloon catheter.Reasonable use of stents is beneficial in decreasing the restenosis.

OBJECTIVETo sum up the experience in diagnosis and treatment of Fournier's gangrene and find an optimal evaluation tool for its prognosis by comparing currently used prognostic scoring systems.
METHODSWe retrospectively analyzed 16 cases of Fournier's gangrene diagnosed and surgically treated in our hospital between 2004 and 2012. Using Fournier's Gangrene Severity Index (FGSI), Uludag Fournier's Gangrene Severity Index (UFGSI), Age-Adjusted Charlson Comorbidity Index (ACCI), and Surgical Apgar Score (sAPGAR) , we obtained the prognostic scores of the patients and made comparisons among different scoring systems.
RESULTSFGSI, UFGSI, ACCI, and sAPGAR were all clinically used scoring systems. Statistically significant differences were found in the scores of ACCI and UFGSI but not in those of FGSI and sAPGAR between the death and survival groups, with the maximum area under the ROC curve and minimum standard error for the ACCI score.
CONCLUSIONBoth ACCI and UFGSI are useful for evaluating the prognosis of Fournier's gangrene. However, ACCI is even better for its higher sensitivity and specificity and easier clinical collection.

To discuss the availability of evaluation on the dissolution studies of the multicomponents in traditional Chinese medicine, the in vitro dissolution of total composition of the tablet of rhizomes of Ligusticum chuanxiong components and its correlation with the in vivo were studied by the method of area under the absorbance-wavelength curve (AUAWC). Taken the tablet of rhizomes of Ligusticum chuanxiong components which is composed of sodium ferulate and ligustrazine hydrochloride as subject model, the dissolution tests were carried out with basket method. The plasma concentrations of tablets in different rats were determined by AUAWC at different interval times. The in vivo absorption percentage was calculated by Wagner-Nelson equation to evaluate the in vitro and in vivo correlation. According to the results, the cumulative dissolution in vitro of total composition of tablets of rhizomes of Ligusticum chuanxiong components at 60 min was 90.65% in water by AUAWC. The in vivo pharmacokinetics is fitted with an one-compartment model. The linear equation based on the cumulative dissolution rate (fr) and absorption percentage (fa) at 5, 10, 20, 30 and 60 min was fa = 0.819 7 fr+0.183 and the correlation coefficient was 0.959 5, which showed a good correlation between the in vitro dissolution and the in vivo absorption percentage. The method of AUAWC can be used accurately, feasibly and conveniently to evaluate the in vitro and in vivo correlation of total composition of tablets of rhizomes of Ligusticum chuanxiong components, which will provide better guidance to study the in vitro and in vivo correlation of sustained release preparation etc under complex system of traditional Chinese medicine in the future.

Objective To investigate the expression of T cell immunoglobulin domain and mucin domain (TIM)-3 and its ligand Galectin-9 in the peripheral blood of initial systemic lupus erythematosus (SLE)patients,and explore their effects on SLE.Methods The percentages of CD4+TIM-3+,CD8+TIM-3+cells from 33 SLE patients and 26 normal controls were detected by flow cytometry,and the Galectin-9 gene expression of PBMCs was determined by real-time PCR The SLE Disease Activity Index(SLEDAI),C3 level and lymphocyte count were evaluated.Mann-Whitney U test was used for independent samples analysis and Spearmen's test was used for correlation analysis.Results The percentages of CD4+TIM-3+ and CD8+TIM-3+ cells were markedly increased in SLE group than those of the control group(P<0.01).In particular,the CD4+TIM-3+,CD8+TIM-3+ level Was positively correlated with SLEDAI (r=0.517,P<0.01;r=0.400,P<0.05);but negatively correlated with C3(r=0.487,P<0.05;r=0.395,P<0.05).The Galectin-9 mRNA in SLE PBMCs was higher than that of the controls(P<0.05).Conclusion TIM-3-Galectin-9 pathway may be involved in T cell immune regulation of SLE,and is related to disease activity.
