Purpose:To evaluate the differences in expression of carcinoembryonic antigen mRNA (CEA mRNA) in various tissues and its use in the diagnosis of digestive tract carcinoma.Methods:There were 35 patients with digestive tract carcinoma and 12 patients with non carcinoma disease in the study. The expression of CEA mRNA in the digestive tract tissues specimens was detected with nested reverse transcriptase polymerase chain reaction(RT PCR). A contrast test was detection of carcinoembryonic antigen (CEA) in blood sepcimen with enzyme linked immunosorbent assay (ELISA). Results:The expression of CEA mRNA in cancer tissues with RT PCR was 29 (82.86%) with positive results and that of CEA in blood with ELISA was 15 (42.86%) in the patients with digestive tract carcinoma. The difference in positive results was significant ( P

Objective To retrospectively evaluate the role of consolidative repeat radiofrequency ablation (CRRFA) based on safety margin (SM) analyses in local tumor control for alpha-fetoprotein (AFP) negative hepatocellular carcinoma (HCC) patients who had been shown to have radiological complete ablation (CA) with radiofrequency ablation (RFA). Methods From July 2002 to July 2009,152 AFP negative HCC patients who were shown to have radiological CA with RFA therapy were retrospectively analyzed. Among them, 110 patients had a SM of less than 1 cm and the other 42 patients had a SM of 1cm or more. Among 110 patients with SM less than 1 cm, fifty nine patients accepted CRRFA within 6 months after the first RFA and 51 did not. From these patients, a narrow SM-CRRFA group (n=41) and a narrow SM-single RFA group (n=37) were enrolled respectively. The wide SM-single RFA group (n= 30) was enrolled from the 42 patients with a SM of 1 cm or more.The LTP (local tumor progression)-free survival rate of the 3 groups were compared with a log-rank test. Results One-, two-, three-, four-, and five-year LTP-free survival rates respectively were 97. 1%, 90.9%, 69.6%, 47.2%, and 33. 0% in the narrow SM-CRRFA patients. 85.9%, 66. 5%,43.5%, 15.8%, and 0. 0%, in the narrow SM-single RFA patients, and were 92.7%, 83.7%,59.3%, 36. 9%, and 9.2% in the wide SM-single RFA patients. There were statistically significant differences (χ2 = 14. 789, P= 0. 001) between the groups. Conclusions An ablation zone with an SM of 1 cm or greater was the most important factor for local control of AFP negative HCC ranging from 3 to 5 cm in diameter. For these patients with a SM of less than 1 cm, CRRFA improved the overall local control outcomes.

The typical manifestations of rheumatoid arthritis are joint pain, swollen and morning stiffness.If the disease is not treated promptly and reasonably,most patients will face joint deformity and physical disability. At present, the choice of evaluation tools related to physical disability is still lack of basis, the influencing factors have not reached the academic consensus, the related interventions are insufficient, rheumatoid arthritis patientsˊ rehabilitation and quality of life can be affected. This article reviews the above three aspects in order to provide the theoretical basis for the development of similar studies and interventions in China.

Objective To compare short-term therapeutic outcomes and the safety of percutane-ous radiofrequency ablation (PRFA) with left single lung ventilation (LSLV) for liver cancer of the hepatic dome (LCHD) and that of PRFA for right liver carcinoma in favorable location. Methods Thirty one patients with hepatocellular carcinoma (belonging to LCHD) receiving PRFA with LSLV (Group LCHD) between January 2006 and January 2009 in our hospital were selected, and 45 control patients with right lobe HCC ≥1 cm away from the liver capsule, gallbladder, and main portal bran-ches were also included. One month after PRFA, residual tumors were followed up with contrast en-hanced CT and alpha fetal protein and PRFA was repeated in the presence of residual foci. Tumor-free survival time was defined as the duration from complete ablation to diagnosed local tumor progression.The Mann-Whitney test was used to compare age, tumor diameter, and average number of punctures between LCHD patients and controls. A χ2 test was used for comparison of the incidence of complica-tions and incomplete tumor ablation rate. The Kaplan-Meier's method was used for calculation of local tumor-free survival rate compared with a log-rank test. Results The incidence of right shoulder pain was significantly higher in LCHD patients than in controls (87. 1% vs 11. 1%, P<0. 01). LCHD pa-tients showed no difference from controls in the average number of punctures (2. 8±. 5 vs 3. 2±. 5,P>0. 05). Meanwhile, there was no difference between the 2 groups in average duration of treatment and hospitalization, and the complete tumor ablation rate at first PRFA. No differences were observed in the 1-, 2- and 3-year local tumor-free survival rates between LCHD patients (85. 5% , 65. 8% , and 36. 4% ,respectively) and controls (87.7%, 62. 3% , and 34.0% , respectively). Conclusion PRFA with LSLV for LCHD seems to promise comparable short-term outcomes and safety to PRFA for right liver carcinoma of fa-vorable location and should be preferred as one of the therapeutic options for LCHD patients with tumor di-ameters≤5 cm regardless of its unique location.

Objective: To explore the effect of anxiety, depression, perceived social support on maternal-fetal attachment (MFA) in women during late pregnancy. Method: A sample of 207 cases of women during late pregnancy was assessed with Maternal Antenatal Attachment Scale, Perceived Social Support Scale and Hospital Anxiety and Depression Scale. Results: Anxiety and depression scores were negatively correlated with MFA scores (r=-0.401,-0.416, P<0.01); perceived social support scores were negatively correlated with anxiety and depression (r=-0.233,-0.362, P<0.01), but positively correlated with MFA scores (r=0.200, P<0.01). The interactive effects of anxiety×perceived social support and depression × perceived social support on MFA were significant(β=0.196、0.204, P<0.01). Conclusion Perceived social support played a moderating role between negative emotion and MFA.

Objective To assess the therapeutic efficacy and safety of CT-guided percutaneous radiofrequency ablation(PRFA) for hepatocellular carcinoma in the bare area (HCCBA). Methods During the period from April 2000 to June 2009, 26 patients with HCCBA were treated with CTguided PRFA, and 26 other HCC patients were selected as controls, whose lesions were located in the right lobe ≥1.0 cm away from the liver capsule, gallbladder, and main portal branches. One month after PRFA, the residual tumors of each patient were examined by contrast-enhanced CT and alpha-fetoprotein test, and repeated PRFA was undertaken if residual was present. Tumor-free survival was defined as the duration from complete ablation to diagnosed local recurrence. The 2-independent-samples t-test was used to compare tumor diameter between HCCBA patients and controls. The MannWhitney U test was used to compare patient's age, etiologies of liver disease, liver function status,number of needle punctures and the value of AFP. A χ2 test was used for comparison of the complete tumor ablation rate and the cumulative local tumor-free survival rate. Results No significant difference was observed in the incidence of complication between the HCCBA patients and the controls (26. 9% vs 19.2%,P＞0.05). There were no differences between the two groups in the number of needle punctures and the complete tumor ablation rate at first PRFA. Furthermore, no differences were observed in the cumulative 1-,3- and 5-year local tumor-free survival rates between HCCBA patients (88. 5%, 46.2% and 19. 2% respectively) and patients in the control group (92.3%, 53.8% and 15.4% respectively). Conclusion CT-guided PRFA is effective and safe for HCCBA and could be preferred as one therapeutic option for HCCBA.

Objective To translate Rheumatoid Arthritis Self-efficacy Scale (RASE) into Chinese and to evaluate its reliability and validity. Methods A total of 188 hospitalized patients with rheumatoid arthritis (RA) were selected as research subjects through convenience sampling method. According to the translation mode of the scale, Chinesization and cultural adjustment were conducted to the English version of RASEto test reliability and validity. Results Item analysis showed that the Chinese version of RASE could discriminate the high-score group from the low-score group (P<0.01). Pearson correlation analysis showed that the correlation coefficient between the score of each item and the total score of the Chinese version of RASE was positively correlated (P<0.01).Exploratory factor analysis extracted a total of 8 common factors, which explained 68.55％of the total variance. The Cronbachαof the Chinese version of RASE was 0.901, and Cronbachαof each dimension ranged from 0.660 to 0.867;the retest reliability was 0.955 after 1 week, and ranged from 0.819 to 0.984 for each dimension;the split-half reliability coefficient was 0.848. Conclusion The Chinese version of RASE has good reliability and validity, which can be applied to the research of self-efficacy of patients with RA in China.

Guided bone regeneration technology applied in alveolar bone defect regeneration is based on the barrier function and space maintenance of the barrier membrane. Therefore, traditional development strategies for barrier membranes focus on their physical barrier function, degradation characteristics and biocompatibility to avoid immunogenicity. However, not only does the barrier membrane passively block connective tissue, it is recognized as a “foreign body”that triggers a persistent host immune response, known as a foreign body reaction. The theories of osteoimmunology reveal a close relationship between the immune system and bone system and emphasize the role of immune cells in bone tissue-related pathophysiological processes. Based on these findings, we propose a novel development strategy for barrier membranes based on immune microenvironment regulation: by manipulating mechanical properties, surface properties and physiochemical properties, barrier membranes are endowed with an improved immunomodulation ability, which helps to regulate immune cell reactions to induce a favorable local immune microenvironment, thus coordinating osteogenesis and osteoclastogenesis as well as barrier membrane degradation to increase the efficiency of barrier membranes in GBR applications. In this paper, we review the development of barrier membranes and their close relationship to the immune microenvironment concerning bone regeneration and membrane degradation. Additionally, the outcomes of research on barrier membranes based on the regulation of the immune microenvironment have been summarized to improve the osteogenesis efficiency of barrier membranes and solve the problem of the regeneration and repair of bone defects, especially alveolar bone defects.

Objective: To investigate the effect of long-term exposure of nitrogen dioxide on the incidence of hypertension. Methods: From March to December 2009, 37 386 eligible residents from four cities in northern China (Tianjin, Shenyang, Taiyuan, and Rizhao) were enrolled in a follow-up study by using the random cluster sampling method. Demographic characteristics, lifestyle, history of diseases, and self-report situation of hypertension were collected by using questionnaire. Based on the average annual concentration of NO₂ during the period from the cohort to the onset of hypertension as an estimate of exposure, the effect of NO₂ exposure on hypertension was analyzed by employing Cox proportional hazards model. The interactions between NO₂ exposure and different characteristics (age, sex, body mass index, smoking, alcohol consumption, education, economy, exercise, and fruit intake) were also examined. Results: The baseline age of residents was (43.74±13.78) years, and the body mass index (BMI) was (22.56±2.92) kg/m². During an average follow-up time of 11.40 years, 2 619 (7.0%) new cases of hypertension were reported. The overall mean environmental pollution levels during the study period for the entire cohort was (40.74±17.07) μg/m³. After adjusting for age, sex, BMI, family history of hypertension, socio-economic information, and lifestyle, the hazard ratio (HR) of incident hypertension with a 10 μg/m³ increase of NO₂ was 1.21 (95%CI: 1.18-1.25). Compared with residents aged 60 years and over (HR=1.19, 95%CI: 1.14-1.26), former and current smoking (HR=1.20, 95%CI: 1.14-1.25), and high-frequency fruit consumption (HR=1.17, 95%CI: 1.13-1.21), residents younger than 60 years (HR=1.28, 95%CI: 1.25-1.32), non-smoker (HR=1.23, 95%CI: 1.19-1.27), and low-frequency fruit consumption (HR=1.27, 95%CI: 1.20-1.35) had stronger interaction effect with NO₂ (all P values for interaction<0.05). Conclusion NO₂ exposure may lead to the onset of hypertension, which has a stronger effect on people younger than 60 years old, without smoking history and with low-frequency fruit consumption.
