Objective To investigate the correlation between RDW and disease activity in patients with IBD and evaluate clinical significance of RDW as a potential indicator to monitor IBD activity. Methods 256 patients with IBD were divided into two groups. One was UC group including 136 patients with 80 active period cases and 56 emission period cases. Another was CD group including 120 patients with 75 active period cases and 45 emission period cases. 60 bacillary dysentery diseases and 80 healthy controls were selected as bacillary dysentery group and healthy control group. RDW, Hb, WBC, PLT, CRP, ESR, MCV were tested and monitored with development of disease at different stages. We compared RDW with CRP,ESR, PLT, Hb, MCV parameters. By ROC curve analysis, the sensitivity and specificity of RDW was estimated in identifying the IBD's activity. Results The mean values of RDW in active UC group, remission UC group, bacillary dysentery group and control group were ( 16. 1 ± 2. 7), ( 13.5 ± 2. 1 ), ( 13.0 ± 2. 0)and ( 12. 8 ± 1.8), respectively. There was significant difference among four groups ( F = 51.9, P < 0. 01 ).RDW in active UC group was significant higher than that in remission UC group, bacillary dysentery group and healthy control group ( t = 8. 12, 9. 67, 11.85, P < 0.05) and RDW in remission UC group was significant higher than that in bacillary dysentery group and healthy control group as well ( t = 2. 45, 2. 67,P <0. 05). The mean values of RDW in active CD group, remissive CD group,bacillary dysentery group and control group were ( 16. 9 ± 2. 2 ), ( 13. 8 ± 1.1 ), ( 13.0 ± 2. 0), ( 12. 8 ± 1.8 ). There was significant difference among four groups ( F = 113.9, P < 0. 01 ). RDW in the active CD group was significant higher than that in remission CD group, bacillary dysentery group and healthy control group (t = 11.47,18.63,18. 72, P < 0. 05 ) and RDW in remission CD group was also significant higher than that in bacillary dysentery group and healthy control group ( t = 3.60, 3. 72, P < 0. 05 ). RDW in UC and CD groups demonstrated a positive correlation with CRP and ESR (r=0. 484, 0. 525, 0. 286, 0. 358 and P<0. 01, <0. 01, < 0. 05, < 0. 01, respectively) but an inverse correlation with Hb and MCV (r = -0. 378, -0. 271,- 0. 329, - 0. 298 and P < 0. 01, < 0. 01, < 0. 05, < 0. 01, respectively). In UC groups RDW represented a larger area under ROC curve (0. 8.54) compared with CRP, ESR, PLT, Fib and MCV. When the cut-off value of RDW was 14. 0, the sensitivity and specificity for identifying active UC were 82% (65/80) and 72% (40/56) respectively. In CD groups, the area of RDW under ROC curve was the largest (0. 925 )among all indicators. When the cut-off of RDW was 14.5, the sensitivity and specificity for identifying active CD was 88% (66/75) and 82% (37/45) respectively. Conclusion RDW in patients with IBD is a useful indicator to estimate the IBD activity and predict disease progression.

OBJECTIVETo compare the effect of electro-acupuncture (EA) and maprotiline (Map) in treating depression.
METHODSThirty patients of depression were treated with EA and 31 patients with Map orally taken respectively. The therapeutic effect and side-effect were evaluated by measurement of Hamilton Depression Rating Scale (HAMD), Self-Rating Scale for Depression (SDS), Self-Rating Scale for Anxiety (SAS), Clinical Global Impression Scale (CGI) and Asberg Rating Scale for side-effects (ARS) before treatment and on the day 14, 28 and 42 of the therapeutic course.
RESULTSAfter treatment, the scores of HAMD and SDS lowered significantly (P < 0.01) than before treatment, and with insignificant difference between the group (P > 0.05). For patients with somatic syndrome, the HAMD score decrease rate was obviously higher in the Map group than that in the EA group. However, for the patients with anxiety somatization syndrome, the score of SAS, ARS in the EA group were significantly lower than those in the Map group (P < 0.05). Moreover, the efficacy index was higher in the EA group (P < 0.01).
CONCLUSIONBoth EA and Map are effective in treating depression.

OBJECTIVETo explore the feasibility and practical value of fluorescence in situ hybridization (FISH) detection of TERC gene amplification in cervical intraepithelial lesions (CIN) and squamous cell carcinoma (SCC).
METHODSTissue microarray was constructed to cover 150 cases of various cervical conditions, including 24 cases of normal cervical mucosa, 78 cases of CINs (CINI, 25 cases; CINII, 21 cases and CINIII, 32 cases) and 48 cases of SCC. FISH was used to detect TERC gene amplification.
RESULTSTERC gene amplification was detected in 8% (2/25) CINI, 47.6% (10/21) CINII, 71.9% (23/32) CINIII and 87.5% (42/48) SCC. There were significant differences among these groups (P < 0.05). The amplification rates of TERC gene in SCC, CINIII and CINII were significantly higher than those of normal cervical epithelium and CINI (P < 0.05). Significant differences were also observed among CINI and CINII, CINIII and SCC (P < 0.05), and between CINII and SCC (P < 0.05). There were no significant differences between normal cervical epithelium and CINI, CINII and CIN III, and between CINIII and SCC (P > 0.05). FISH detection of amplification of TERC gene in CINI and CINII-III demonstrated the following statistics: sensitivity of 62.3%, specificity of 92.0%, accuracy of 71.8%, positive and negative predictive values of 94.3% and 53.5%, respectively.
CONCLUSIONSFISH detection is a reliable method in detecting TERC gene amplification using paraffin tissue sections. When histological evaluation becomes difficult, TERC amplification detectable by FISH may offer a diagnostic distinction of CINI from CINII. Moreover, TERC amplification may be used as a biomarker in predicting CIN progression to invasive cancer.
