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.

Objective To explore the use of Swedish medical company CMS 4.6.4 radiotherapy XIO system for the design process of cervical cancer postoperative IMRT plans in different iterative times of the same case,and to observe the Segment Weight Optimization(SWO)effect generated after the plan results.Methods Ten cases of cervical cancer patients were chosen ,the use of XIO 4.6.4 CMS treatment system was performed for the development of the intensity modulated radiation therapy .In the SWO process , iterative times were used to generate different plans ,without affecting the clinical dose target area requirements , and compared the organs at risk( OAR) by determining whether there were differences between dose and the number of segments ,monitor units (MU).Results For the same patients,different iterative times within a certain range of SWO IMRT plan were selected to compare the different iterative times plan ,femoral head,rectum and the bladder dose did not change the basic plan.The total number of segments and MU did not change significantly (P>0.05).Conclusion IM-RT plans in the use of CMS XIO 4.6.4 design of cervical cancer after operation in the process of using the itera-tive times below 100 times for SWO is the most suitable method for ensuring the organ dosimetry in radiotherapy . The total number of segments and the MU reduces the radiotherapy plan time so as to improve work efficiency .

Objective To compare three kinds of irradiation treatment plans for cervical and upper thoracic esophageal cancer,in order to arrived at proper decision for the patient.Methods From February 2001 to June 2004,43 such patients were studied with three different simulated treatment plans made including conformal plan,conventional four-field plan and conventional two-field plan for every one.All plans were evaluated with iso- dose curve and dose-volume histogram.Results GTV on 95% isodose curve was 99.5%,98.2% and 87.4% in conforaml plan,conventional four-field plan and conventional two-field plan,respectively;PTV_1 and PTV_2 on 95% isodose with 97.8%,97.2%,94.8% and 95.8%,86.6%,73.7%.The volume of＞20 Gy dose of left lung accepted was 18.6%,17.2% and 32.3%,in conformal plan,conventional four-field plan and conventional two-field plan,respectively;the right lung received 20.5%,19.9% and 35.5%.Conclusions Conformal plan is the best in radiotherapy,as it can provide ideal dose distribution of irradiated target with adequate protection of the normal tissues.Conventional four-field plan,being easy to carry out,can replace the conformal plan in most situations.Conventional two-field has the most uneven dose distribution and largest lung volume irradiated.

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.

Objective To explore the relationship of proteinuria,immunopathogenesis and humoral immunity in children with Henoch-schonlein purpura nephritis(HSPN).Methods Serum IgG,IgA,IgM,C3 and C4 levels were detected with complete-automatic biochemistry analyzer in 47 children with HSPN and 18 heathy children,and the differences in the findings were compared among groups.The levels of IgG,IgA,IgM,C3 and C4 were compared among groups according to the count of proteinuria.The renal tissues were adopteded with immunity in the children with HSPN were taken for biospy examination,and the differences in immunopathalogy were compared among groups with immunof-luorescence assay.Results The IgG,IgA levels in children with HSPN were higher than those of heathy children,on the contrary,the IgM,C3 and C4 levels were lower than those of heathy children(Pa0.05),but the IgM level of the nephritic syndrome group were higher than that of other groups(Pa0.05).Conclusions There is severe disturbance of immunologic function in children with HSPN.There is no connections among serum IgG,IgA,IgM,C3 and C4 levels,proteinuria and renal immunopathlogy.

OBJECTIVETo investigate the sociopsychological basis of hypertensive disorder in pregnancy (HDP) and explore a new pathway for etiological study of HDP.

METHODSA prospective investigation was conducted in 1154 women in second trimester pregnancy and 9 factors were surveyed using Olson marital quality questionnaire (ENRIC). The discrepancy between the norms and factor scores of ENRIC was analyzed, and the scores of ENRIC were compared between normal gravidas and patients with HDP. The correlation between ENRIC scores and the severity of the condition was also evaluated.

RESULTSThe score of the 1124 gravidas for marital satisfaction was significantly higher than the norm (P<0.05), but the scores for relationship with relatives and sexual life were significantly lower (P<0.05). The other 6 factors had similar scores with the norms (P>0.05). Patients with HDP had significantly lower scores for 7 factors than the normal gravidas (P<0.05), but had comparable scores for financial arrangement and sexual life (P>0.05). The severity of HDP was not found to associate with variation of the scores for the 9 factors (P>0.05).

CONCLUSIONSMarital quality is an important social and psychological basis of HDP, and this study provides some evidence for the social and psychological investigation of the etiology of HDP.
