Background and purpose:Correct target positioning is an important factor affecting the precision of stereotactic body radiotherapy (SBRT) in patients with lung tumors. This study investigated the setup errors in patients with malignant lung tumors receiving SBRT with cone-beam CT (CBCT) and analyzed the factors influencing setup errors.Methods:Twenty-nine patients with solitary malignant lung tumors were enrolled in the study. Each patient underwent SBRT with CBCT before each treatment. Setup errors in CBCT were obtained according to the matched and planned CT images in anterior-posterior (AP), superior-inferior (SI) and left-right (LR) directions. The expanding margins of clinical target volume (CTV) to planning target volume (PTV) according to the analyzed setup errors were then calculated. And the influencing factors of setup errors were analyzed.Results:A total of 155 CBCT images from 29 patients were obtained during the treatment. The setup errors were (-1.68±3.62), (-1.34±3.90) and (0.36±2.15) mm in the AP, SI and LR directions, respectively. The absolute setup errors were (3.16±2.42), (3.29±2.48) and (1.74±1.30) mm in the AP, SI and LR directions, respectively. The suggested expanding margins of CTV to PTV were 9.6, 10.0 and 5.3 mm in the AP, SI and LR directions according to the setup errors. The setup errors in the AP direction of peripheral lesions and in the SI direction of inferior, right and metastatic lesions were relatively larger(P=0.007, 0.008, 0.000 and 0.000)..Conclusion:In patients with malignant lung tumors receiving SBRT, the setup errors were more obvious in the SI and AP directions. Tumor motion management techniques including CBCT, breath-holding technique are required to reduce the setup error in patients with lung tumors receiving SBRT.

Objective To identify the histological features as well as factors influencing the course of HBeAg-negative chronic hepatitis B virus ( HBV)-infected patients with persistently normal alanine amino-transferase (ALT) levels (PNAL). Methods Ninety-eight HBeAg-negative chronic HBV-infected patients with PNAL who underwent percutaneous liver biopsy were recruited from October 2003 to March 2008. The ALT level, HBV markers, HBV DNA level and liver histological changes were detected. Comparison of means was done by t test and single factor analysis of variance. Nonparametric statistics was done by Marm-Whitey U test and Kruskal-Wallis test. Analysis of independent risk factor was done using Logistic model. The dianostic value of ALT level to significant liver histological changes was evaluated by receiver performance curve. Results Twenty-two point four percent and 17.3% of subjects had the histological activity index (HAI)≥4and fibrosis (F) score≥3 respectively. Subgroup analysis showed that subjects with ALT＞0.50 × upper limit of normal (ULN) had a significantly higher rate of HAI≥4 and F score≥3 than those with ALT≤0.50×ULN (HAI≥4:36.4% vs 11.1%, χ2 =8.881, P=0.003;F score≥3:27.3% vs 9.3%, χ2 =5.487, P= 0.019, respectively), and older subjects (more than 45 years old) had a higher proportion of HAI ≥4 than the younger (33.3% vs 13.4%, χ2 =4.923, P=0.027). Multivariate Logistic regression analysis revealed that a decade increase in age was the independent predictor of HAI≥4 (OR=2.410, P=0.023).Receive operating characteristic (ROC) curve showed that 87.0% and 90.7% of subjects with ALT＜0.50× ULN had histological changes of HAI＜4 and F score＜3 respectively. The proportions of HAI≥4 and F score≥3 in subjects with HBV DNA＜1×104 copy/mL were 14.9% and 12.8%, respectively. Conclusions Significant histological changes may be present in part of the subjects with persistently normal ALT and different HBV DNA levels, so that liver biopsy is very important, especially in those with age ＞45 years.Half time the ULN may serve as an appropriate cutoff value of normal ALT level for managing Chinese HBeAg-negative chronic HBV-int'ected patients.

Objective To elucidate the roles of TANK-binding kinase-1(TBKl)in hepatitis B virus (HBV)infection induced interferon antiviral immunity.Methods Peripheral blood monocytes were separated by CD14 magnetic microbeads from healthy volunteers(HV)and chronic hepatitis B(CHB)patients.Purified mDCs were induced and proliferated in the culture medium with human granulocyte-macrophage concentration of 25 mg/L were stimulated.The mRNA expressions of TBK1,interferon regulatory factor (IRF)3 and interferon(IFN)-βwere quantified by real time polymerase chain reaction(PCR).The levels of IFN-β in supernatants were determined by enzyme-linked immunosorbent assay(ELISA).Reslllts The mRNA levels of TBK1,IRF3 and IFN-β did not change significantly at 0,12,24 and 48 h after the significantly at 0, 12, 24 and 48 h in CHB group, whereas, it was significantly up-regulated at 12 h in HV group. Conclusions Our results suggest that there may be some disorders in host antiviral signal transduction pathways downstream the binding between ligands and receptors on mDC surface. The insufficient IFN-β expression after HBV infection may result in persistent chronic infection.

OBJECTIVETo investigate the effect of Tongxinluo capsule (TXLC) on the patients with unstable angina pectoris (UAP).

METHODSPatients of UAP were divided into two groups, the treated group (n = 60) was treated with TXLC and the Danshen group (n = 30) was treated with composite Danshen tablet. The plasma endothelin (ET) and calcitonin gene related peptide (CGRP) were measured before and after treatment. Data were compared between the two groups and also compared with those measured in 20 healthy subjects for control.

RESULTSET level was higher and CGRP level lower significantly in UAP patients than that in healthy subjects significantly (P < 0.05). After TXLC treatment, ET significantly lowered (P < 0.01) and CGRP increased (P < 0.05). But in the Danshen group after treatment, the former decreased (P < 0.05), while the latter remained unchanged (P > 0.05). The effect of TXLC was better than that of composite Danshen tablet.

CONCLUSIONTXLC is an effective drug for UAP treatment, which could efficiently regulate the ET and CGRP metabolism and ameliorate the degree of myocardial ischemia damage.

OBJECTIVETo observe the effect of umbilical sticking therapy (UST) with Qitou Xiaugu Plaster (QXP) on hemodynamics of portal system in patients with liver cirrhosis.

METHODSOne hundred and twenty patients of liver cirrhosis with portal hypertension were assigned to two groups. On the basis of conventional therapy, UST was applied in the 66 patients in treated group, which was exchanged once every 3 days with an interval of 1-day rest. The 54 patients in the control group were orally administered with propanolol. The therapeutic course for both groups was 1 month. Before and after treatment, the hemodynamic changes in portal or splenic veins were observed by color Doppler ultrasonograph, and the changes of liver function, blood coagulation and patients' subjective symptoms were observed as well.

RESULTSAfter treatment, portal vein diameter and splenic vein diameter significantly decreased (P < 0.05, portal venous flow velocity and splenic venous flow velocity apparently increased (P < 0.05), and portal venous flow apparently decreased in both groups (P < 0.05), while no significant change was found in the splenic venous flow (P > 0.05). The liver function and blood coagulation indexes in both groups were improved. The improvement of clinical symptoms in the treated group was superior to that in the control group.

CONCLUSIONUST with QXP could decrease the portal vein pressure in a short time, with the therapeutic effect comparable to propanolol, and with no adverse reaction.
