OBJECTIVETo investigate the relationship between hemostatic changes in liver cirrhosis patients with different degrees of their liver lesions.
METHODSForty-three patients (35 men, 8 women; age: 25 to 71 yr) with liver cirrhosis were divided into three subgroups (A, B, and C) on the basis of Child-Pugh classification. Among the patients, 13 were classified as Child-Pugh class A, 15 were class B, 15 were class C. 16 healthy individuals served as controls. A series of hemostatic tests and parameters including prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib), factors II, V, VII, VIII, IX, X, vWF assay, antithrombin-III (AT-III), protein C (PC), D-dimer, tissue plasminogen activator antigen (t-PA), plasminogen activator inhibitor activity (PAI) were performed on 43 patients and the 16 healthy controls.
RESULTSPT and APTT were progressively prolonged from A to B and then to C. In comparison to the controls there was a significant difference. Fibrinolytic activity and the activities of factors II, V, VII, IX, X were progressively decreased from A to B and then to C. In comparison to the controls there was a significant difference . AT-III and PC activity were progressively decreased from A to B and then to C. In comparison to the controls there was a significant difference. D-dimer and t-PA-antigen were progressively increased from A to B and then to C. In comparison to the controls there was significant difference. PAI activity did not display significant changes in the four groups.
CONCLUSIONWe found that there is a close relationship between the severity of cirrhosis and the hemostatic changes. Because the deterioration of the coagulation function and increasing fibrinolytic activity parallel the severity of liver cirrhosis, adequate treatment for cirrhotic bleeding should not only correct the coagulation defects, but also lower the increased fibrinolytic activity.

PURPOSETo explore the needs for basic community-based rehabilitation services for disabled persons in Xuanwu District, Beijing, China, and to identify factors which influence disabled persons to accept rehabilitation services.
METHODOne hundred and eight disabled persons were selected by systematic sampling and simple random sampling to assess their needs for community-based rehabilitation services.
RESULTSOf the interviewees, 57.4% needed the community-based rehabilitation services, but only 13.9% took advantage of it. The main factors influencing the interviewees to accept these services were cost (P < 0.05), knowledge about rehabilitation medicine (P < 0.05); and the belief in the therapeutic benefit of the community-based rehabilitation service (P < 0.05).
CONCLUSIONA considerable gap exists between the supply of community-based rehabilitation services in Beijing and the needs for these services by disabled residents underscoring the need for improved availability, and for additional research.

OBJECTIVETo explore the changes in the mRNA expression of adiponectin (Adp), adiponectin receptors(AdpR), and leptin in different adipose tissues of Wannanhua pigs at different stages of development, and their sexual dimorphism.
METHODSFive Wannanhua boars and five Wannanhua gilts were sampled at birth, 30, 45, 90, and 180 days of age respectively. The delta delta Ct relative quantification real-time PCR was used to detect the transcription levels of Adp, AdpR1, AdpR2, and leptin mRNAs in subcutaneous (SC) and perirenal (PR) adipose tissues, and beta-actin were used as internal standards.
RESULTSThe expression level of Adp, AdpR1, AdpR2, and leptin mRNA in SC and PR adipose tissue were changed with age significantly (P < 0.01). In general, Adp mRNA expression in SC adipose tissue was significantly lower than that in PR adipose tissue (P < 0.05), while AdpR1, AdpR2, and leptin mRNA expression in SC adipose tissue were significantly higher than those in PR adipose tissue (P < 0.05 or P < 0.01). Although the sexual dimorphism were found in apart genes or apart days of age, Adp, AdpR1, AdpR2, and leptin mRNA expression both in SC adipose tissue and PR adipose tissue had no significant differences between Wannanhua gilts and boars in general. Significant positive correlation was found between Adp and AdpR1, AdpR2 (P < 0.05 or P < 0.01), and significant negative correlation was found between Adp and leptin (P < 0.05) in SC adipose tissue and PR adipose tissue respectively (P < 0.05).
CONCLUSIONThe expression of Adp, AdpR1, AdpR2, and leptin mRNA in adipose tissue of Wannanhua pigs followed specific developmental patterns and tissue specificity. Adp correlated with its receptors.

Background:
Dysimmunity plays a key role in diabetes, especially type 1 diabetes mellitus. Islet-specific autoantibodies (ISAs) have been used as diagnostic markers for different phenotypic classifications of diabetes. This study was aimed to explore the relationships between ISA titers and the clinical characteristics of diabetic patients.
Methods:
A total of 509 diabetic patients admitted to Department of Endocrinology and Metabolism at the Affiliated Hospital of Nantong University were recruited. Anthropometric parameters, serum biochemical index, glycosylated hemoglobin, urinary microalbumin/creatinine ratio, ISAs, fat mass, and islet β-cell function were measured. Multiple linear regression analysis was performed to identify relationships between ISA titers and clinical characteristics.
Results:
Compared with autoantibody negative group, blood pressure, weight, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), visceral fat mass, fasting C-peptide (FCP), 120 minutes C-peptide (120minCP) and area under C-peptide curve (AUCCP) of patients in either autoantibody positive or glutamate decarboxylase antibody (GADA) positive group were lower.Body mass index (BMI), waist circumference, triglycerides (TGs), body fat mass of patients in either autoantibody positive group were lower than autoantibody negative group. GADA titer negatively correlated with TC, LDL-C, FCP, 120minCP, and AUCCP.The islet cell antibody and insulin autoantibody titers both negatively correlated with body weight, BMI, TC, TG, and LDL-C. After adjusting confounders, multiple linear regression analysis showed that LDL-C and FCP negatively correlated with GADA titer.
Conclusion
Diabetic patients with a high ISA titer, especially GADA titer, have worse islet β-cell function, but less abdominal obesity and fewer features of the metabolic syndrome.

OBJECTIVETo evaluate the feasibility, therapeutic effects and complications of three-dimensional conformal radiotherapy (3DCRT) for small-cell lung cancer (SCLC).
METHODSThe data of 19 SCLC patients treated between June 2001 and August 2003, with 3DCRT were reviewed and analyzed. Eighteen patients were treated by radiotherapy plus chemotherapy while only 1 patient by radiotherapy alone. Radiotherapy was delivered at 2 Gy/fraction, 5 fractions per week with a median total dose of 54 Gy. Chemotherapy consisted of 4 - 6 cycles of etoposide and cisplatin or carboplatin. The median follow-up time was 24 months.
RESULTS(1) The overall response rate after 3DCRT was 79.0%, with a complete remission rate of 31.6% (6/19), partial remission rate of 47.4% (9/19). The 1- and 2-year overall survival (OS) was 71.7% and 35.8% respectively, with a median survival time (MST) of 19 months, and both the 1- and 2-year local progression free survival (LPFS) were 94.7%. (2) Of these 19 patients, grade 2 acute radiation pneumonitis developed in 5.3%, grade 2 late radiation pneumofibrosis in 5.3%, grade 2 acute radiation esophagitis in 10.5% and grade 2 acute hematologic toxicity in 10.5%.
CONCLUSIONThree-dimensional conformal radiotherapy is feasible in the treatment of SCLC with high response rate and acceptable complications. Further observation, more patients treated by 3DCRT and prolonged follow-up are needed to evaluate remote survival.

PURPOSE: The purpose of this study was to investigate the function of Zinc finger protein 488 (ZNF488) in nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS: The endogenous expression of ZNF488 in NPC tissues, normal nasopharyngeal epithelium tissues and NPC cell lines were detected by quantitative reverse transcription polymerase chain reaction. ZNF488 over-expressing and knock-down NPC cell line models were established through retroviral vector pMSCV mediated over-expression and small interfering RNA (siRNA) mediated knock-down. The invasion and migration capacities were evaluated by wound healing and transwell invasion assays in ZNF488 over-expressing and control cell lines. Soft-agar colony formation and a xenograft experiment were performed to study tumorigenic ability in vitro and in vivo. Immunofluorescence and western blotting analysis were used to examine protein changes followed by ZNF488 over-expression. Microarray analysis was performed to explore gene expression profilings, while luciferase reporter assay to evaluate the transcriptive activity of Tcf/Lef. RESULTS: ZNF488 was over-expressed in NPC tissues compared with normal tissues, especially higher in 5-8F and S18, which are well-established high metastatic NPC clones. Functional studies indicate that over-expression of ZNF488 provokes invasion, whereas knock-down of ZNF488 alleviates invasive capability. Moreover, over-expression of ZNF488 promotes NPC tumor growth both in vitro and in vivo. Our data further show that over-expression of ZNF488 induces epithelial mesenchymal transition (EMT) by activating the WNT/beta-catenin signaling pathway. CONCLUSION: Our data strongly suggest that ZNF488 acts as an oncogene, promoting invasion and tumorigenesis by activating the Wnt/beta-catenin pathway to induce EMT in NPC.

OBJECTIVETo provide information on epidemiology of rotavirus infection in Beijing, China.
METHODSAn ongoing hospital-based surveillance was conducted among children < 5yr old with acute diarrhea according to WHO generic protocol (CID-98). During a 3-year study (Apr. 1998 to Mar. 2001), a total of 484 stool samples were collected from 1 457 patients, including 275 samples from 1 048 outpatients and 209 samples from 409 inpatients.
RESULTSThe overall detection rate of rotavirus infection was 25.4%. Rotavirus was responsible for 27.3% of diarrhea inpatients on a yearly base, and 46.2% during rotavirus season. Two peaks of diarrhea were observed each year, one in the summer (June-Sep.) due to bacterial dysentery (16.7%) and another in fall winter (Oct.-Dec.) due to rotavirus infection (23.0%). The detection rate on rotavirus was the highest in age group of 6 - 11 months (38.2%), followed by 1 - 2 years old (28.5%). Ninety six point eight percentage of children were infected under 3 years of age. The number of deaths, possibly caused by rotavirus diarrhea were accounted for 40% of all diarrhea deaths and 11.1% of the total deaths. Serotyping of 123 rotavirus isolates showed that serotype G1 (55.3%) was predominant, followed by G2 (26.8%), G3 (9.8%), G4 (0.8%), and 10 isolates (8.1%) remained non-typeable. Mixed infections (0.8%) seemed to be rare.
CONCLUSIONRotavirus diarrhea was an important infectious disease among children in Beijing. Safe and effective rotavirus vaccines for the prevention of severe diarrheas and the reduction of treatment costs are of significant importance to China.

BACKGROUND:
Pulmonary vein (PV) occlusion generally depends on repetitive contrast agent injection when cryoballoon ablation for atrial fibrillation (AF). The present study was to compare the effect of cryoballoon ablation for AF guided by transesophageal echocardiography (TEE) vs. contrast agent injection.
METHODS:
Eighty patients with paroxysmal AF (PAF) were enrolled in the study. About 40 patients underwent cryoballoon ablation without TEE (non-TEE group) and the other 40 underwent cryoballoon ablation with TEE for PV occlusion (TEE group). In the TEE group during the procedure, PVs were displayed in 3-dimensional images to guide the balloon to achieve PV occlusion. The patients were followed up at regularly scheduled visits every 2 months.
RESULTS:
No differences were identified between the groups in regard to the procedure time and cryoablation time for each PV. The fluoroscopy time (6.7 ± 4.2 min vs. 17.9 ± 5.9 min, P < 0.05) and the amount of contrast agent (3.0 ± 5.1 mL vs.18.1 ± 3.4 mL, P < 0.05) in the TEE group were both less than the non-TEE group. At a mean of 13.0 ± 3.3 mon follow-up, success rates were similar between the TEE group and non-TEE group (77.5% vs. 80.0%, P = 0.88).
CONCLUSIONS
Cryoballoon ablation with TEE for occlusion of the PV is both safe and effective. Less fluoroscopy time and a lower contrast agent load can be achieved with the help of TEE for PV occlusion during procedure.
