Objective To explore the allergic status and allergen composition in children with acute Henoch-Schonlein Purpura in Wuxi by allergen detection, thereby to establish appropriate therapeutic strategies. Methods Two hundred and forty-six patients with Henoch-Schonlein Purpura in their acute phase were examined for serum concentrations of total IgE and specific IgE using Germany AllergyScreen system. Results The positive rate of allergen-specific serum IgE was 48.7% (120/246) ,of which,positive reactions to two or more than two allergens were found in 86 cases (34.9%) and that to one kind of allergen were found in 34 cases (13.8%)The positive rate of total serum IgE was 78.9% (194/246). In inhalation allergen group, positive reaction to allergen was found in 134 cases (54.5%). The most common allergen was dust mite/flour mites (19.1%) ,and came the next were house dust(17.1%) and Penicillium notatum/Alternaria alternata(10.2%). In food allergen group,positive reaction to allergen was found in 77 cases (31.3%). The most common allergen was fish (6.5%),and came the next were egg (5.7%) and mutton (5.3%). We found no significantly different allergen positive rates between inhalation allergens group and food allergens group (χ2 = 2.59, P ＞ 0.05). Conclusions The combined allergens attacks were more common in children patients with acute Henoch-Schonlein Purpura by serum allergen detection. Various types of the allergens are associated with the occurrence of acute Henoch-Schonlein Purpura. To reduce the harmness of allergens,it is necessary to avoid touching these allergens.

Objective To study the correlation between early cognitive function and severity of pain in elderly patients after operation. Methods Selective open abdominal operation was performed in 30 elderly patients admitted to our department from January 2009 to June 2009. Severity of pain was assessed using visual analogue scale ( VAS) and cognitive function was scored with Mini-Mental State Examination ( MMSE) ,animal fluency test ( AFT) and clock drawing test ( CDT) ,respectively,in 24 and 48 h after operation. Cognitive function of the patients was assessed from the view of neurophysiology. Pain was scored after operation with VAS. Variables were analyzed with the linear correlation analysis. Correlation between early cognitive function and severity of pain in elderly patients was observed after operation. Results No linear correlation was observed between scores on MMSE,VAS and AFT scales in 24 and 48 h after operation ( r = -0. 053,P = 0. 786; and r = -0. 052,P = 0. 783; and r = -0. 323,P = 0. 082; and r = -0. 038,P = 0. 841). A negative linear correlation was found between scores on CDT and VAS scales in 24 and 48 h after operation ( r = -0. 731,P =0. 000; and r = -0. 636,P = 0. 001). Conclusion Cognitive function including visual space structure function and implementing function in elderly patients after operation is correlated with the pain scores on VAS scale.

Objective To compare the proteome difference between multiple myeloma cell line U266 cells treated and untreated with PS-341, to investigate the potential drug targets, and to provide theoretical evidence for clinical therapy of multiple myeloma. Methods Two-dimensional gel electrophoresis (2-DE) was performed to separate proteins from treated and untreated U266 cells with proteasome inhibitor PS-341. ImageMaster 2D Platinum software was used to analyze 2-DE image, and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) was used to identify the differentially expressed proteins. The expression levels of differential protein BAG-2 in the 2 groups of U266 cells lines were detected by Western blot. Results The 2-DE reference pattern of treated and untreated U266 cells with PS-341 was established. A total of 31 differential proteins were identified by MALDI-TOF-MS, 27 of which were down-regulated after PS-341 treatment. The differential expression level of BAG-2 in the 2 groups of U266 cells was confirmed by Western blot. Conclusion Some down-regulated proteins may be the potential drug targets of proteasome inhibitor PS-341.

Objective To observe the effect of reperfusion therapy on the prognosis of acute myocardial infarction (AMI) complicated by eardiogenic shock(CS)in reperfusion era.Methods 89 cases of AMI with CS were included with 57 male and 32 female.50 cases received conservative therapy and 39 cases reperfusion therapy.28 of the 39 cases had suecessflll reperfusion and 11 eases failed.18 patients had intra-aortic balloon pump (IABP) within 1 hour of CS,they constituted an early group;35 patients treated with IABP 1 hour after CS were of a late group.A group of 36 cases were not treated with IABP (no IABP group).Results The mortality of the early group with IABP Was significantly lower than that of the late and no IABP group(33.3% vs.74.2% vs.86.1%,P＜0.01).The mortality of the group with sucessful reperfusion was significantly lower than that of unsuccessful reperfusion and conservative no IABP group (42.8% vs.81.8% vs.84.0%,P＜0.01).logistic regression analysis showed that successful reperfusion therapy (OR 4.232,95% CI 1.407～12.730,P=0.01) and THE TIME of using IABP(OR 0.22.95% CI 0.063～0.764,P=0.017)were independent risk factors for death.Conclusion Early successful reperfusion and early institution of IABP were the most important therapeutic measures for reducing mortaliIv of AMI complicated by CS.

Objective To study the differences of esophageal manometry (M),pH set-up method (P) and X-ray (X) on positioning of the 24-hour esophageal pH catheter and relative factors. Methods Fifty subjects underwent M, then pH catheter was located by P and X. The difference between methods and the relative factors such as body height,lower esophageal sphincter (LES) length etc were analyzed. The difference of less than 2 cm between two methods was accepted. Results The length between the location determined by M,Pand X and nose were (37.9 ±2.9),(40.8 ±4.4) and (40.7 ±5.3) cm, respectively.There was significant difference between P and M as well as between X and M (P＜ 0.01 ). The coincidence rate was 62.0%(31/50) between P and M;84.0%(42/50) between P and X;and 58.0%(29/50) between X and M. Compared with P,M was (2.9 ±3.9) cm nearer to the stomach. Age, body height and LES length were main factors which affect the difference between P and M (P＜ 0.01 or ＜ 0.05),body height and LES length were main factors which affect the difference between X and M (P＜0.05 or ＜0.01). Conclusions Compared with M, the location determined by P is nearer to stomach. The location of X is varied. Body height and LES length are main relative factors.

Objective To assess the prevalence of Personality Diagnostic Questionnaire (PDQ)personality deviations in patients referred for functional dyspepsia (FD) with reliable and universal psychological measures, and to explore the relationship between co-occurring PDQ-personality deviations and functional dyspepsia. Methods The sample comprised 246 patients referred for functional dyspepsia. Four groups were divided according to their patterns of gastrointestinal symptoms: the FD group, FD with refluxlike symptom group(FD + RS group), FD with irritable bowel syndrome group( FD + IBS group), and FD with reflux-like symptom and irritable bowel syndrome group ( FD + RS + IBS group). Participants were assessed with the Personality Diagnostic Questionnaire for DSM-Ⅳ ( PDQ-4 ) to evaluate the presence of personality deviations. Results Overall 65% patients scored positive for any personality deviation, male and female alike. Cluster C (anxious/fearful) personality was most commonly found in FD patients (142 patients, 57.7% ). The FD + IBS group and the FD + RS +IBS group had significantly higher total PDQ scores than the FD group (23.39 ± 8. 77 and 24. 22 ± 10. 97 vs 18.98 ± 11.88, P ＜ 0. 05, respectively),indicating that FD patients with greater level of personality deviations tend to report other symptoms involving the esophagus and lower gastrointestinal tract. Reflux-like symptom without actual pathological acid regurgitation indicated cluster A (odd/eccentric) personality deviations. Conclusions The current study shows personality deviations are common in patients referred for functional dyspepsia. Negative emotions,maladaptive coping, and lack of social support, may strongly influence their healthcare-seeking behavior.There is no single personality type specific for some kind of gastrointestinal symptom. But FD patients with personality deviations tend to report other symptoms involving the esophagus and lower gastrointestinal tract.
