ABSTRACT:Many studies show that helminth‐derived molecules can induce immunoregulatory cells to form immune net‐work‐mediated immune ,thereby inhibiting allergic and autoimmune diseases .Helminth parasites can induce immune cell activa‐tion and produce cytokine .And parasites play an inhibitory effect to affect other immune related diseases .However ,the associ‐ation between helminths infections and immune related diseases does not always have an unequivocal outcome .While some hel‐minths infections protect against allergic diseases ,other helminth can exacerbate this immunopathology .

Objective To explore the expression of the nuclear factor -κB (NF-κB) regulating monocyte ehemoactracttive peptide -1 ( MCP-1) in asthma patients, and investigate the effect of seretide, budesonide and vento-lin. Methods 81 asthma patients were randomly divided into seretide therapy group and budesonide and ventolin therapy group. The NF-κB activation in PBMC and the plasma concentrations of MCP-1 were measured by ELISA. ventolin therapy group (1.70±0.39) ng/L of asthma patients were significantly higher than that control group (0.89±0.34) ng/L ( P<0.001 ) ; The plasma MCP-1 level in seretide therapy group ( 66.89±5.62 ) ng/L and in budesonide and ventolin therapy group (73.35±7.52 ) ng/L of asthma patients were also significantly higher than level of seretide therapy group in asthma patients were significantly lower than budesonide and ventolin therapy group (P <0.001 ). Conclusion NF-κB gene and its regulating protein MCP-1 may be involved in asthma. Glucocotios-teroid and beta2 agonists combination may prolong the process of asthma.

Objective To explore the changes and the clinical relevance of plasma p-selectin (PS) and vascular endothelial cell function in patients with carotid stenosis (CS) before and after carotid artery stenting (CAS). Methods The plasma levels of PS, yon willebrand (vWF) and endothelin-1 (ET-1) before CAS and 1hour,6 hours,24 hours,2 months after CAS in 67 patients with carotid stenosis and 54 cases of TIA with negative result from cerebral angiography were measured. The patients of the therapy group were further divided into group A and group B according to complexity of CAS. The plasma levels of PS and vWF were determined by enzyme linked immunosorbent assay,and the level of ET-1 was measured by radioimmunoassay. Results The plasma levels of PS,vWF and ET-1 all increased in the patients group after CAS. In the therapy group,the level of PS reached peak value (29.23 ± 6.98) ng/ml 1 hour after CAS, and the levels of vWF and ET-1 reached peak value (119.63 ±16.75) %, (79.71 ± 9.78) ng/L 6 hour after CAS. In therapy group, there was significant difference in the levels of PS and ET-1 between each time points after CAS and before CAS (P＜0.05,P ＜0.01 respectively). There was significant difference in the level of vWF between 1 hour, 6 hours, 24 hours after CAS and before CAS (P ＜ 0.05 orP ＜ 0.01). There was significant difference in tihe levels of PS 1 hour after CAS and ET-1 at 6 hours after CAS (P ＜0.05) ,and in the level of vWF at 1 hour,6 hours after CAS between control group and therapy group (P ＜0.01).There was significant difference in the level of vWF at every time point after CAS (P ＜ 0.05 or P ＜ 0.01), and in the level of ET-1 at 1 hour,6 hours,24 hours between A group and B group(P ＜0.05 or P ＜0.01). Conclusions PS, vWF and ET-1 were activated to some extent and related to pathological changes degree and complexity of CAS. Monitoring these biological indexes after CAS maybe of great value in predicting risk, evaluating clinical therapy and judging prognosis.

BACKGROUND:For the department of orthopedics, digital technology can be used for a three-dimensional reconstruction of the fracture site, and visual virtual reset. This not only can preoperatively plan the operation path, make reasonable operation plan, but also can predict the prognosis after surgery. OBJECTIVE:To discuss the feasibility and clinical effect of digital technology for three-dimensional measurement and preoperative design in intertrochanteric fracture patients undergoing proximal femoral nail antirotation. METHODS:Eighty patients of intertrochanteric fractures, who underwent proximal femoral nail antirotation in the Changyi People’s Hospital from January 2010 to January 2014, were selected in this study. According to the order of visiting, they were randomly divided into traditional treatment group and three-dimensional design group, with 40 cases in each group. Patients in the traditional treatment group received proximal femoral nail antirotation. Patients in the three-dimensional design group received preoperative CT scan to establish the digital three-dimensional model of intact femur. The analog was reset by technology. The length and diameter of medul ary cavity were measured. The appropriate specifications of intramedul ary nail were selected. On this basis, the plan of the operation and implementation of operation were made. Operation time, intraoperative bleeding volume and blood transfusion were recorded in the two groups. Hip function was evaluated by hip Harris score. RESULTS AND CONCLUSION:(1) Operations in the two groups were successful. Significant differences in operation time, intraoperative bleeding volume and blood transfusion were determined between the two groups (P<0.05). No significant difference in length of stay was detected between the two groups (P>0.05). (2) Al patients were fol owed up. Postoperative wound was healed. Broken nail or broken rod was not found at the end of the study. (3) At the end of the fol ow-up, the excel ent and good rate of Harris hip score was 95%in the traditional treatment group and 93%in the three-dimensional design group;no significant difference was detected between the two groups. (4) Results suggested that the application of digital department of orthopedics technology for the treatment of intertrochanteric fracture of femur in patients with preoperative three-dimensional measurement and surgical design can significantly shorten the operation time and improve hip function.

(2) The rate of depressive disorder increased with age from 0.10% (6～8 years) to 2.59% (≥ 15 years) . (3) The co-morbidity was 40% . The most common comorbidity diagnosis was anxiety disorders (29.1%) and behavior disorders (25.5%) . Conclusion: The prevalence of depressive disorder among children and adolescents in Chengdu is 1.2%. Gender and age may be the related factors. The co-morbidity is common in children and adolescents with depression disorder.

Objective To discuss the method and efficiency of less invasive stabilization system (LISS) in treatment of comminuted tibia[ fractures. Methods A total of 14 patients with comminuted tibial fractures were treated with LISS between January 2005 and July 2006. There were 10 males and four females, at age range of 19-61 years (mean 34 years). Of all, 11 patients were with proximal fractures of tibia and three with distal ones, including six with open fractures and eight with closed ones. The period from injury to operation was 2-13 days. An observation was done on postoperative soft tissue recovery and fracture healing. Results The average period of follow-up was 9.4 months (4-16 mouths). All frac-tures were healed up after average 7.8 months (4-12 months). All incisions were healed up at one stage, with no complications on nerves, blood vessels or soft tissues. The axes of tibia were good, with sound function of knee and ankle joints. Conclusion LISS is characterized by easy operation, minor trauma, high healing rate and low complications in treatment of comminuted tibial fractures.
