OBJECTIVETo gain some insights into the critical events relating to HBV transcriptional regulation by comparing HBV replicative characteristics in different cell lines.

METHODSHepatic cell lines QSG-7701 and HepG2 were transfected with plasmid PUC18-HBV 1.2 by standard calcium phosphate precipitation method, and 1.0 microg pSEAP2-control vector was included in the transfection procedures to serve as an internal control monitoring the transfection efficiency. Hepatitis B surface antigen (HBsAg) in the medium was detected by ELISA method and HBV DNA was quantitated using fluorescent quantitative PCR. The intracellular HBsAg and HBcAg were detected with immunofluorescent staining. The gene expression profiles of QSG-7701 and HepG2 were compared using oligonucleotide microarray; partial differentially expressed genes were verified with quantitative RT-PCR.

RESULTSIn the medium of the cultured HepG2 cells, HBsAg and HBV DNA could be detected 6 days after the transfection, whereas in QSG-7701 cells, the HBsAg and HBV DNA could be detected for 2 weeks. The HBV DNA in the culture medium of QSG-7701 was about 50 times more than that of the HepG2 cells which were kept in 1 x 10(7)copies/ml(-3) x 10(7)copies/ml for 0 to 10 days after the transfection. On the 4th day after the transfection, 20% to 30% of the QSG-7701 cells were positive with HBsAg and HBcAg immunofluorescent staining. The gene microarray analysis showed that most transcription factors involved with HBV life cycle in QSG-7701 and HepG2 cells had similar levels, whereas some factors involved with HBV transcriptional regulation and core particle disassembly, such as interleukin-6 (R=5.1340), retinoid X receptor, alpha (R=5.1268), hepatic leukemia factor (R=3.2538), serine protease PRRS23 (R=2.8356), hepatitis B virus x interacting protein (R=0.4939), serine protease inhibitor Kazal type 1 (R=0.0740) and matrix metalloproteinase 3 (negative in QSG-7701) were all differentially expressed by HepG2 cells.

CONCLUSIONDifferent than HepG2 cells, the QSG-7701 cells could support a high level and relatively stable HBV replication after HBV DNA transient transfection. The HBV core particles were probably recycled in the QSG-7701 cells. The differential gene expressions between QSG-7701 and HepG2 might explain the mechanism of the different HBV replication patterns. Hepatic cell line QSG-7701 might serve as a useful tool for HBV transcriptional regulation research.

OBJECTIVETo study the efficacy and safety of Eviprostat for the treatment of benign prostatic hyperplasia (BPH).

METHODSAn open, multicentral clinical trial was conducted in 100 patients with BPH. Patients received a 12-week oral administration of Eviprostat 2 tablets per-time, 3 times a day. The main indexes of efficacy include international prostatic symptom score (IPSS), maximum urinary flow rate (Qmax), residual urine ( Ru) and prostatic volume (V). The additional indexes are quality of life score (QOL) and average urinary flow rate (Qave).

RESULTSAfter a 12-week therapy, IPSS, QOL score, Qmax and Qave were significantly improved. IPSS was averagely decreased by 5.67 (P < 0.001); QOL score was averagely decreased by 1.44 (P < 0.001); Qmax was averagely increased by 1.70 ml/s (P <0.001); Qave was averagely increased by 1.15 ml/s (P < 0.001); Ru was averagely decreased by 5.07 ml (P = 0.046) , PSA level was averagely decreased by 0.129 microg/L (P < 0.017). The clinical adverse event rate was 1%.

CONCLUSIONEviprostat is a kind of safe, effective and preferable drug for treating BPH. It can improve the subjective symptoms and objective measures of the patients.

OBJECTIVETo evaluate the prognostic value of plasma brain natriuretic peptide (BNP) and C-reactive protein (CRP) in patients with acute coronary syndromes (ACS) underwent percutaneous coronary intervention (PCI).

METHODSPatients with ACS underwent PCI in our hospital from December 2004 to September 2005 were included in this study. Plasma BNP (n = 189) and CRP (n = 141) were measured at a median of (34.2 +/- 16.3) hours from symptom onset, total mortality and the risk for major adverse cardiac events (MACE, including death, recurrent MI, recurrent angina, heart failure, readmission for any reason) at 30 days and at 3 months was analyzed.

RESULTSPatients were divided into 4 groups according to their BNP levels (BNP 100 ng/L to 300 ng/L to 600 ng/L) and the 3-month mortality was 0%, 1.4%, 7.7%, 48.3% and 3-month incidence of MACE was 7.9%, 17.1%, 57.7%, 79.3% respectively. Multivariate logistic regression analyses showed that the plasma BNP level predicted 30-day (r = 0.8515, P < 0.01) and 3-month (r = 0.9201, P < 0.01) mortality and 30-day (r = 0.7066, P < 0.01) and 3-month (r = 0.7090, P < 0.01) incidence of MACE independent of other known prognostic factors such as age, gender, family heredity, hypercholesterolemia diabetes, hypertension, smoking and LVEF. Patients were divided into 3 groups according to their CRP levels (CRP 8.0 mg/L to 32.0 mg/L) and 3-month mortality was 2.7%, 7.7% and 28.6% and 3-month incidence of MACE was 28.4%, 41.0% and 60.7% respectively. CRP predicted 30-day (r = 0.5882, P = 0.0044) and 3-month (r = 0.5235, P = 0.0038) mortality independent of traditional risk factors, and predicted 30-day (r = 0.2705, P = 0.0380) and 3-month (r = 0.2290, P = 0.0429) incidence of MACE after adjustment for patient age. CRP lost its predictive value after BNP was introduced into the model, while BNP was still an independent predictor for mortality and incidence of MACE at 30 days and 3 months in ACS patients underwent PCI.

CONCLUSIONBoth plasma BNP and CRP are good predictors for early mortality and MACE incidence in ACS patients underwent PCI.

OBJECTIVETo investigate the change in dendritic cells (DCs) in children with chronic immune thrombocytopenia (cITP) and the effect of glucocorticoid on DCs in children with cITP.

METHODSFifteen children with cITP and 20 healthy controls were included in the study. Flow cytometry was used to measure the DC subsets count in the 15 children with cITP before and after glucocorticoid treatment as well as the corresponding values in the 20 healthy controls. The DCs derived from peripheral blood monocytes in children with cITP were cultured in vitro and collected, and their immunophenotypes were determined by flow cytometry.

RESULTSBefore glucocorticoid treatment, the children with cITP showed no notable change in the absolute count of myeloid DCs (mDCs) but showed decreased absolute count of plasmacytoid DCs (pDCs) and increased mDC/pDC ratio compared with the healthy controls (P<0.05). After glucocorticoid treatment, the children with cITP demonstrated increased absolute count of pDCs and decreased absolute count of mDCs and mDC/pDC ratio compared with before treatment (P<0.05). Before glucocorticoid treatment, the children with cITP had significantly higher positive rates of HLA-DR, CD80, CD83 and CD86 on peripheral blood DCs than the healthy controls (P<0.01). All the positive rates were significantly decreased after glucocorticoid treatment (P<0.01), so that there was no significant difference from the healthy controls (P>0.05).

CONCLUSIONSDisproportion and functional disturbance of DC subsets is associated with the pathogenesis of cITP in children. Glucocorticoid can strengthen the immunosuppression of DCs in children with cITP, which may contribute to the effectiveness of glucocorticoid as a treatment.

OBJECTIVEThe purpose of this study was to investigate the clinicopathologic factors associated with false-negative rate of sentinel lymph node biopsy (SLNB) in breast cancer, and to explore how to reduce the false-negative rate of SLNB.

METHODSThe clinicopathological data of 2265 patients with invasive breast carcinoma who underwent sentinel lymph nodes biopsy (SLNB) in Shandong Cancer Hospital between November 1999 and December 2011 were retrospectively analyzed. We screened 1228 patients who received axillary lymph node dissection after SLNB, and studied the clinicopathological factors that could be associated with false-negative rate of SLNB.

RESULTSThe false negative rate of this group was 10.7% (73/683), accuracy rate was 94.1% (1155/1228), and negative predictive value was 88.2% (545/618). Clinical tumor size (all P < 0.05), calendar year of surgery (all P < 0.05) and numbers of detected SLNs (all P < 0.05) were significantly related with false negative rate and accuracy rate of SLNB, determined by single factor analysis. Logistic regression model analysis showed that calendar year of surgery (P = 0.034) and numbers of detected SLNs (P = 0.012) were independent predictive factors for the false negative rate of SLNB.

CONCLUSIONSFalse negative rate and accuracy rate of SLNB are significantly related to the calendar year of surgery and number of detected SLNs. Strict case selection, standard operation procedure, increaseing numbers of detected SLNs, and improvement of the skill of operators are effective measures to reduce the false negative rate of SLNB.

OBJECTIVETo investigate the clinical characteristics of diffuse large B-cell lymphoma (DLBCL) and the factors affecting its prognosis.

METHODSFrom 1994 to 2002, 138 patients with DLBCL were confirmed by morphological and immunohistochemical examination. Sex, age, clinical stage, performance status (PS), serum lactate dehydrogenase (LDH), number of extranodal lesions, treatment response, cycles of chemotherapy, B symptom, erythrocyte sedimentation rate (ESR), 5-year survival rate and median survival time (mST) were included as the analysis indeces.

RESULTSLymph nodes were involved in 87.7% of the patients, and extranodal lesions were found in 60.1%. Five-year survival rate was 41.3% for the entire group. Age, stage, PS, serum LDH, number of extranodal lesions, international prognostic index (IPI) and remission rates were significantly correlated with overall survival (OS) and mST (P < 0.05), However, sex, chemotherapy cycles, B symptom, ESR were not related to OS and mST (P > 0.05). Age, stage, remission rates were identified as independent factors affecting the prognosis. Combination of surgery and chemotherapy was quite impressive in the prolongation of survival of patients with extranodal lesions and gastrointestinal lymphoma compared to those by chemotherapy alone.

CONCLUSIONAge, stage, PS, serum LDH, number of extranodal lesions, IPI, chemotherapy cycles and remission rates are significant factors affecting the prognosis in DLBCL patients. Age less than 40 years or >/= 65 years, Stage III-IV, partial remission or progressive disease are demonstrated as poor prognostic factors. Combined treatment is the strategy suggested for DLBCL patients with extranodal lesions.

Accurate prenatal diagnosis of complex congenital cardiovascular anomalies,vascular ones in particular,is still challenging.A fetal cardiovascular cast model can provide a copy of the cardiac chambers and great vessels with normal or pathological structures.This study was aimed to demonstrate three-dimensional anatomy of complex congenital cardiovascular anomalies in fetuses by means of corrosion casting.Twenty fetuses with prenatal-ultrasound-diagnosed complex cardiovascular anomalies were enrolled in this study (19 to 35 gestational weeks).Fetal cardiovascular cast models were made by a corrosion casting technique.The specimens were injected with casting material via the umbilical vein,and then immersed in strong acid after casting fluid was solidified,to disclose the geometries of cardiovascular cavities.Nineteen cast models were successfully made from 20 specimens.The casts distinctly showed the morphological malformations and spatial relationship between cardiac chambers and great vessels.One hundred and eleven abnormalities were revealed by casting in the 19 specimens,including 34 abnormalities located in the cardiac chambers (3,4 and 27 anomalies in the atria,atrioventricular valves and ventricles,respectively),and 77 in the great vessels (28,20,24 and 5 anomalies in the aorta and its branches,the pulmonary artery,the ductus arteriosus and the major veins,respectively).Corrosion casting can display three-dimensional anatomy of fetal complex cardiovascular anomalies.This improves our understanding of related pathomorphology and prenatal diagnosis.

Objective To investigate the efficiency and complications of stereotactic surgery combined with intra-operative electrocorticography (ECoG) and intra-operative neurophysiologic monitoring (IOM) in treating epilepsy secondary to subcortex small tumors in the functional areas.Methods Fifteen patients with epilepsy secondary to subcortex small tumors in the functional areas,admitted to our hospital from June 2006 to June 2011, were chosen in our study. Resection was performed to these tumors. Guiding with stereotaxic apparatus, epileptogenic foci and boundary localizing by intra-operative ECoG monitoring,functional areas and neuronal structures in the epileptic region judging by IOM,the epileptogenic foci were resected or performed multiple subpial wansaction (MST) and/or cortices lower output powers thermocoagulation.The treatment efficacy was concluded.Results Total resection was achieved in 13 patients and subtotal resection in 2.Epileptogenic foei were ablated in 4 patients,and peri-lesioned cortex of epileptogenic foci in other 11 patients were performed lower output powers thermocoagulation or/and MST. ECoG monitoring found epileptiform discharge disappearance in 6 patients,residual of a few spikes in 6,residual of a lot of spikes as well as having mild to moderate abnormal basilic rhythms in EEG in 3.No permanent and severe complications were noted.All patients were followed up for 1 to 3 y; tumor recurrence was noted in 2; according to Engel's classification standards,Engel I was noted in 10,Engel Ⅱin 3 and Engel Ⅲ in 2,and the effective rate was 100％. Conclusion Stereotactic surgery combined with intra-operative ECoG and IOM is a safe,effective and microinvasive management for epilepsy secondary to subcortex small tumor in the functional areas; it can accuratly locate and totally resect the tumors,treating the epileptogenic foci and avoiding functional defects.

Background: Right upper lobectomy (RUL) for lung cancer with different dissecting orders involves the most vari-able anatomical structures, but no studies have analyzed its effects on postoperative recovery. This study compared the conventional surgical approach, VAB (dissecting pulmonary vessels first, followed by the bronchus), and the alter-native surgical approach, aBVA (dissecting the posterior ascending arterial branch first, followed by the bronchus and vessels) on improving surgical feasibility and postoperative recovery for lung cancer patients. Methods: According to the surgical approach, consecutive lung cancer patients undergoing RUL were grouped into aBVA and VAB cohorts. Their clinical, pathologic, and perioperative characteristics were collected to compare periop-erative outcomes. Results: Three hundred one patients were selected (109 in the aBVA cohort and 192 in the VAB cohort). The mean operation time was shorter in the aBVA cohort than in the VAB cohort (164 vs. 221 min, P < 0.001), and less blood loss occurred in the aBVA cohort (92 vs. 141 mL, P < 0.001). The rate of conversion to thoracotomy was lower in the aBVA cohort than in the VAB cohort (0% vs. 11.5%, P < 0.001). The mean duration of postoperative chest drainage was shorter in the aBVA cohort than in the VAB cohort (3.6 vs. 4.5 days, P = 0.001). The rates of postoperative complica-tions were comparable (P = 0.629). The median overall survival was not arrived in both cohorts (P > 0.05). The median disease-free survival was comparable for all patients in the two cohorts (not arrived vs. 41.97 months) and for patients with disease recurrences (13.25 vs. 9.44 months) (both P > 0.05). The recurrence models in two cohorts were also comparable for patients with local recurrences (6.4% vs. 7.8%), distant metastases (10.1% vs. 8.3%), and both (1.8% vs. 1.6%) (all P > 0.05). Conclusions: Dissecting the right upper bronchus before turning over the lobe repeatedly and dissecting veins via the aBVA approach during RUL would promote surgical feasibility and achieve comparable postoperative recovery for lung cancer patients.
