Objective: To discuss the effect of early enteral nutrition support on immunological function in patients with acute stroke. Methods: Forty-nine stroke patients with dysphagia were randomly allocated into study group (n = 24) and control group (n = 25). They were received enteral nutrition via nasogastric tube and ordinary nasal feeding of liguid diet, respectively within 72 hours after admission. The levels of total lymphocyte count (TLC), immune globulin A (IgA), immune globulin G (IgG), immune globulin M (IgM), complement 3 (C3), and complement 4 (C4) in both groups were detected on day 1, 7 and 21 respectively after admission. The changes of nutritional index and the incidence of infective complications were observed. Results: The levels of TLC [(2.1 ± 0.4) × 109/L], IgA [(2.7 ± 0.5) g/L], IgG [(11.1 ± 2.2) g/L], IgM [(1.7 ± 0.7) g/L], and C3 [(1.2 ± 0.2) g/L] in the study group were significantly higher than the levels of TLC (1.7 ± 0.4 × 109/L, P < 0.05), IgA [(2.0 ± 0.4) g/L, P < 0.01], IgG [(8.9 ± 2.5) g/L, P < 0.01], IgM [(1.3 ± 0.6) g/L, P < 0.05], and C3 [(1.0 ± 0.3) g/L, P < 0.01] in the control group after 21 days. The incidence of infective complications in the study group (29.1%) was significantly lower than that in the control group (60.0%; P < 0.05). The nutritive index of the study group was also significantly better than that in the control group. Conclusion: Early enteral nutrition support may improve the immunological function in patients with acute stroke, and decrease the incidence of infective complications.

OBJECTIVETo investigate the differences in the condylar position of subjects with skeletal class I and skeletal class II. To provide a basis of diagnosis and treatment.

METHODSGroup A was composed of 50 subjects with skeletal class I (27 males and 26 females; age range = 18 years to 30 years; mean age=26 years). Group B comprised 50 subjects with skeletal class II (24 males and 26 females; age range = 18 years to 28 years; mean age=25 years). The condylar position and the shapes of the condyle and the glenoid fossa were linearly measured on the sagittal and coronal sections by cone-beam computed tomography (CBCT). Data were analyzed by SPSS 19.0.

RESULTSNo statistically significant differences were found in the measurements of the condylar position between the sides of each group on the sagittal plane and the coronal plane (P > 0.05). There were significant differences on the anterior space and the posterior space between group A and B (P < 0.05). The A/P joint space ratio of group A was larger than that of group B (P < 0.05).

CONCLUSIONThe subjects of skeletal class I show an anterior condyle position. The subjects of skeletal class II show a posterior condyle position.

Objective To investigate the changes of CA125 between primary cytoreductive surgery and interval debulking surgery for prediction the rate of optimal interval cytoreductive surgery and prediction the recurrence and the prognosis in patients with epithelial ovarian cancer.Methods A total of 39 cases with suboptimal primary cytoreductive surgery admitted from Jan.1996 to Jan.2009 were retrospectively analyzed.The median age of patients was 56 years( range:41 -68 years).Based on the changes in CA125level between primary cytoreductive surgery and interval debulking surgery,all cases were divided into four groups,group A (CA125 reduced to normal after primary cytoreductive surgery,n=6),group B (CA125reduced to normal after 1 - 2 cycles of chemotherapy,n =11 ),group C ( CA125 reduced to normal after 3 -4 cycles of chemotherapy,n =14),and group D ( CA125 did not reduced to normal after the chemotherapy,n =8 ), and all received platinum-based chemotherapy.The response to chemotherapy evaluated by pathological examination versus CA125 level,and recurrence and prognoses were also analyzed.Results ( 1 )The rate of optimal interval cytoreductive surgery in group A,B,C and D were 6/6,8/11,9/14 and 2/8respectively,in which there were statistically different between group A or B and group D (P ＜0.05).(2)The clinical benefit rates evaluated by the pathological examination in group A,B,C and D were 4/6,4/11,5/14 and 0,respectively and there were statistically different between group A and group D (P =0.030).( 3 ) There was significant difference in the recurrence rate between group A and group D (3/6 vs.8/8,P =0.024),while there were not significant differences between group B or C and group D ( all P ＞ 0.05 ).The rate of drug-resistant recurrence in group A,B,C and D were 1/6,3/11,5/14 and 7/8,respectively,in which there were significant differences between group A,B or C and group D ( all P ＜ 0.05 ). ( 4 ) The median progression-free survival (PFS) for patients in group A,B,C and D were 32,10,18 and 3 months,respectively,in which there were significant differences in the PFS between group A,B or C and group D (P =0.012,P =0.003,P =0.032 ).The median overall survival (OS) were 44,45,44 and 16 months,respectively.There were significant differences in the OS between group A,B or C and group D ( P =0.022,P =0.004,P =0.000 ).Conclusion The change of CA125 between primary cytoreductive surgery and interval debulking surgery may be predict the recurrence type and the prognosis in patients with epithelial ovarian cancer.

Objective To study the relationship of serum visfatin level and coronary heart disease (CHD). Methods Eighty eight hospitalized patients were enrolled into the study and divided into CHD group(n = 62) and non-CHD control group(n = 26) according to the angiography results; the CHD group was further divided into single-, double-, multi-vessel affected groups. The serum level of visfatin was measured by ELISA,the lesion severity of coronary arteries was assessed by Gensini coronary scoring system, and the correlation between serum visfatin level and coronary lesion severity was evaluated statistically. Results The level of serum visfatin was significantly higher in CHD group than the control group([ 10. 77 ± 2. 63 ] μg/L vs. [ 7. 13 ± 2. 06 ]μg/L,P ＜ 0. 05). The visfatin level increased along with the the number of stenosis vessels(P ＜ 0. 05). The sermn visfatin levels of no stenosis, single-, double-, multi-vessel groups were(7. 13 ± 2. 06) μg/L,(9. 30±2. 19) μg/L,(10. 81 ± 2. 12) μg/L,(12. 79 ± 2. 20) μg/L respectively. A significant positive correlation was found between coronary lesion severity score and serum visfatin level(r = 0. 483, P ＜ 0. 01). Conclusion The visfatin may be directly related to the initiation and development of coronary diseases. The higher level of serum visfatin was, the more severe coronary artery disease would be.
