Objective To explore the effect of standardized rehabilitation training and acupuncture therapy on knee osteoarthritis(KOA).Methods One hundred KOA patients were evenly divided into the treatment group and the control group by random digits table.The control group were treated by acupuncture plus general functional exercise guidance and the treatment group by standardized rehabilitation training and treatment for 3 courses(10 d as 1 treatment course).After 3 courses,the two groups were observed in terms of knee joint pain,joint function improvement and clinical curative effect.Result After treatment,the treatment group was significantly better than the control group in terms of knee joint pain,joint function improvement and clinical curative effect(all P<0.05 ).Conclusion The standardized rehabilitation training combined with acupuncture therapy may be effective in the reduction of the knee pain and improvement of knee function for patients with osteoarthritis.

Objective To explore the variation of insulin like growth factor-I (IGF-I) and glucose and correlation in children with sepsis. Methods Forty-two children with sepsis in pediatric intense care unit were enrolled from January 2009 to January 2010. In the morning (2nd morning) after admission, the blood glucose, serum IGF-I, cortisol, insulin, IL-6, and IGF-binding protein-I (IGFBP-1) were detected. In the 3rd and 5th morning, the serum IGF-1 was detected again. According to the blood glucose level of the 2nd morning, the children with sepsis were divided into hyperglycemia group and normal group. Meanwhile, 60 healthy children were served as control group. The data had been compared among three groups. Results In the 2nd morning, the levels of blood glucose, serum IGF-I, cortisol, insulin, and IL-6 were signiifcantly different among three groups (all P<0.05), but the serum IGFBP-I was not signiifcantly different (P>0.05). Compared with control group, the sepsis children with hyperglycemia and with normal blood glucose all had signiifcantly higher serum levels of cortisol and IL-6, and signiifcantly lower serum level of IGF-I. In the 2nd, 3rd, and 5th morning, the serum levels of IGF-1 were not signiifcantly changed with time in sepsis children with hyperglycemia and with normal blood glucose (all P>0.05). Meanwhile, there were no signiifcant differ-ences in the serum levels of IGF-1 between sepsis children with hyperglycemia and with normal blood glucose in the 2nd, 3rd, and 5th morning (all P>0.05). In children with sepsis, the blood glucose and serum IGF-1 was not correlated in the next morning (r=0.152, P=0.267). Conclusions The serum level of IGF-I decreased but maintain stable in children with sepsis. The change of blood glucose may be not related with IGF-I.

Objective To explore the variation and clinical significance of growth hormone(GH) and insulin like growth factor-Ⅰ(IGF-Ⅰ) in children with critical disease.Methods One hundred and twenty-two cases were recruited into the study,among which 42 cases were sepsis in paediatric intensive care unit (sepsis group),20 cases had finished the cardiopulmonary bypass surgery without infection (surgery group).Sixty healthy children served as control group.Serum levels of GH and IGF-Ⅰ were deteced with immunochemiluminometric assay.Results The serum levels of GH were (6.71 ± 6.62) ng/ml in sepsis group,(8.86 ±8.06) ng/ml in surgery group,(3.87 ± 3.31) ng/ml in control group.Compared with the control group,the serum levels of GH in sepsis group and surgery group were increased significantly (P ＜ 0.05).There was no significant difference between sepsis group and surgery group.The serum IGF-Ⅰ levels were (63.72 ±54.17) ng/ml in sepsis group,(119.06 ± 102.12) ng/ml in surgery group and(154.22 ± 107.10) ng/ml in control group separately.The serum IGF-Ⅰ level of sepsis group was significantly decreased compared to the other two groups (P ＜ 0.05).There was no significant difference between surgery group and control group (P ＞0.05).In sepsis group,compared with those who died,the GH of the survival showed no significant difference,IGF-Ⅰ was significantly increased.(P ＜ 0.05).Conclusion GH playes a positive effect in patients with critical disease.IGF-Ⅰ decreases greatly in patients with serious infection.It suggests that IGF-Ⅰ could be a sensitive marker for reflecting whether there is serious infection.The sharply decreasing of IGF-Ⅰ may predict a bad outcome.

Objective To investigate the variation of interleukin-6 ( IL-6 ) , vascular endothelial growth factor(VEGF),E-selectin and intercellular adhesion molecule-1(ICAM-1)in children with sepsis and the clinical significance. Methods This was a prospective and control study. Thirty-two children diagnosed as sepsis in PICU from December 2008 to December 2009 served as the sepsis group. According to whether there was a shock, sepsis group were divided into shock subgroup and no shock subgroup. Fifteen healthy children served as control group. The serum levels of IL-6,VEGF,E-selectin and ICAM-1 were detected with enzyme linked immunosorbent assay. Results The serum level of IL-6 was 65. 00(30. 49~237. 14) ng/L in shock subgroup and 48. 68(30. 25~75. 00) ng/L in no shock subgroup,which were significantly higher than that in control group[0. 80(0. 60 ~1. 00) ng/L](P<0. 05). There was no significant difference between shock subgroup and no shock subgroup. The serum levels of VEGF and E-selectin showed no significant differences among the three groups. The serum level of ICAM-1 was 998. 72(666. 93~1 526. 44) ng/ml in shock subgroup,and 925. 71(683. 53~1 225. 12) ng/ml in no shok subgroup,which were significantly high-er than that in control group[660. 59(525. 48~685. 47) ng/ml]. Compared with those who survived in sep-sis group,the serum levels of VEGF and E-selectin in the died children with sepsis showed no significant difference,but IL-6 and ICAM-1 significantly increased(P<0. 05). Conclusion IL-6 and ICAM-1 increase greatly and accentuate inflammation in septic patients,the changes of which may help to determine the prog-nosis of sepsis.

Objective To evaluate the effectiveness and predictive value of high-resolution manometry(HRM) for POEM in treating achalasia. Methods A total of 84 achalasia patients categorized into subtypes by HRM, who also underwent POEM, were enrolled in our study. Eckardt score, Barium esophagogram and HRM were performed before, 6 months and 1 year after POEM. Results POEM was successfully performed in all 84 patients. No perforation occurred in any patient. The Eckardt scores and esophageal diameter after POEM significantly reduced compared with those before(P<0. 05). The 4s-IRP decreased from 33. 4±9. 0 mmHg (1 mmHg =0. 133 kPa) to 14. 6±3. 8 mmHg six months after POEM (P<0. 05) and to 16. 4±3. 9 mmHg one year after POEM (VS preoperate, P<0. 05). The LESP before treatment was 41. 8±15. 4 mmHg, decreasing to 18. 4±7. 1 mmHg six months after POEM (P<0. 05) and 20. 7±7. 6 mmHg one year after POEM (VS preoperate, P <0. 05) . When categorizing patients into 3 subtypes by HRM, 4s-IRP of type II showed the most dramatic decrease six months after POEM(62. 8%), followed by typeⅠ(53. 5%), while type III had the least decrease(41. 8%). The mean decreasing rate of LESP in type III was 42. 3% six months after POEM, followed by typeⅠ(55. 3%) , while type II showed the highest rate(57. 8%). Conclusion POEM is a safe treatment for achalasia and has significant short-term efficacy with Type II responding best to POEM. HRM plays a vital role in typing AC and predicting the effectiveness of POEM and can be useful in selecting an appropriate treatment.

OBJECTIVETo explore the role of histone H3 acetylation in cleft palate induced by 2, 3, 7, 8-Tetrachlorodibenzo-p-dioxin (TCDD) in C57BL/6J mice, and its mechanism.

METHODSOn gestation day 10 (GD10), 36 pregnant mice were randomly divided into two groups as the treated group(n = 18) and the control group( n = 18). The mice in the treated group received intragastric administration with TCDD 28 μg/kg, while the mice in the control group received equivalent corn oil. The pregnant mice were sacrificed on GD13. 5, GD14. 5 and GD15. 5, collecting fetal palates to determine the activities of histone acetyltransferases (HATs) by Colorimetric and the expression level of acetylated histone H3 (Acetylated histone H3, Ac-H3) by Western-blot.

RESULTSThe activity of HATs was 0.409 7 ± 0.0147, 0.522 3 ± 0.017 1 and 0.643 5 ± 0.013 9 in control group on GD13.5, GD14.5 and GD15.5; 0.865 0 ± 0.0129, 0.719 1 ± 0.017 8 and 0.551 2 ± 0.016 8 in TCDD group. The activity of HATs in TCDD group was higher than that in control group on GD13. 5, GD14. 5, showing significantly difference between the two groups (t = - 56. 932, t = - 19. 516, P < 0.01); however, the activity of HATs in TCDD group was significantly lower than that in control group on GD15. 5 (t = 10. 382, P < 0.01). The expression level of Ac-H3 was 0.745 0 ± 0.113 5, 1.055 9 ± 0.249 4 and 1.795 5 ± 0.081 9 in control group on GD13. 5, GD14. 5 and GD15. 5; while 1.4490 ± 0. 1460, 1. 641 8 ± 0.099 7 and 1. 512 1 ± 0. 150 2 in TCDD group. The expression of Ac-H3 in TCDD group was higher than that in control group on GD13. 5, GD14. 5, showing significantly difference( t = -6. 593, -3. 779, P <0. 01, P <0.05) ; However, the expression of Ac-H3 in TCDD group was statistically lower than that in control group (t = 2. 870, P <0. 05).

CONCLUSIONThe acetylation of histone H3 was involved in the cleft palate of C57BL/6J mice induced by TCDD, which may be one of the mechanisms in TCDD-induced cleft palate.
