Objective To evaluate the clinical significance of measuring IL-13 in serum and dynamics of pulmonary function in infants with bronchiolitis.Methods A total of 50 infants with bronchiolitis(30 in acute phase,20 in recovery phase) and 20 infants in healthy controls were recruited into this study.IL-13 level in serum were detected with Sandwich enzyme linked immunosorbent assay(ELISA),at the same time the object′s respiratory function were tested,then the above indexes were compared.Results The level of serum IL-13 in recovery phase of bronchiolitis was significantly lower than that in acute phase of bronchiolitis and those of both 2 groups were significantly higher than that in control group(all P0.05).Conclusions IL-13 plays a role in pathogenesis in infants with bronchiolitis.The reduction of level of IL-13 will contribute to recovery of infants with bronchiolitis.During the acute phase of bronchiolitis higher resistance can be seen.

The liver is an important organ of the body,with an extraordinary capacity for responding to physical or chemical injuries by regenerating. The mechanisms behind liver regeneration are very complicated as hundreds of substances are involved.However,most of them are not liver-specific,such as HGF,EGF etc. We recently isolated a pure protein with hepatic stimulatory activity from the extract of a weanling calf liver and named its hepatopoietin Cn (HPPCn).This paper,with reference to our own work, mainly reviews the development and bioactivity about hepatic stimulator substance(HSS),augmenter of liver regeneration(ALR),hepassocin(HPS) and HPPCn,which are liver-specific biologically active peptides.

More and more studies have shown that NOD-like receptor protein 3 (NLRP3) inflammasome has become the regulatory factor of inflammatory response and protective immunity, and the assembly and activation of NLRP3 inflammasomes are closely related to the anti-tumor immunity effect. Depending on the cell type and stimuli, activation of the NLRP3 inflammasome can induce immune cells to become polarized, hyperactive, or pyroptotic, releasing interleukin (IL)-1β and IL-18, which leads to cascade immune or inflammatory responses, and its role in tumor immunity has received extensive attention. Here, we review the mechanisms of the NLRP3 inflammasome enhancing CD8⁺ T cells-mediated anti-tumor immunity by inducing the pyroptosis of tumor cell, the pyroptosis or hyperactive state of dendritic cells (DCs), and the pyroptosis or polarization of the macrophages. Different anti-tumor immune roles of NLRP3 inflammasome activation in tumor cells and immune cells provide new directions for future research and may influence the development of next-generation immunotherapy.

Objective: To observe the clinical effect on treatment of Tourette's syndrome with combination of acupuncture and Chinese herbs. Method: Sixty cases were randomly divided into acupuncture-Chinese group and western drug group, which have been treated with acupuncture plus modified Tranquilizing Liver-wind Decoction and orally taken holoperidol respectively.Result: Therapeutic effect comparison between the two groups showed a significant difference (P＜0.05).Conclusion: Combination of scalp acupuncture and Chinese herbs has good effect in treating Tourette's syndrome, with better result than western drug.

To investigate the genetic diversity among wild Dipsacus asperoides in China, 66 germplasmic resources of D. asperoides were analyzed by Start Codon Targeted Polymorphism (SCoT) molecular markers. Genetic distance was calculated by TREECONW software and the systematic diagram of genetic relationship was clustered by UPGMA method. The results showed that the totals of 181 bands were detected using 20 primers , among which 109 were polymorphic bands. The average percentage of polymorphic bands was 60.13%. Genetic distance changed from 0.030 6 to 0.181 4. The clustering results showed that there was no significant correlation between the classification of the wild D. asperoides and their geographical origin. The relatively high genetic diversity of D. asperoides provides the basis for breeding new varieties.

Objective To study the MRI manitestation of juvemle acute pure cartilage fracture of the knee joint.Methods The MRI changes of cartilage,subcartilage low signal line and subcartilage bone were analysed retrospectively in 26 juvenile patients with acute pure cartilage fracture confirmed by arthroscopy.Sagittal and coronal MRI scanning were performed in 26 patients.Using fast low angle shot fat saturation T_1-weighted image(FLASH-FS-T_1WI)sequences,spin echo T_1-weighted image(SE-T_1WI)and fast imaging with steady-state precession three dimensional fat saturation T_2-weighted image(FISP-3D-FS- T_2WI)sequences in sagittal plane,SE-T_1WI and multi echo data image combination T_2-weighted imaging (MEDIC or ME-T_2WI)in coronal plane.Using ME-T_2WI sequence,axial plane MRI scanning in 5 patients.Results Twenty-seven sites of 26 patients include 8 patella,7 femoral medial condyle, 11 femoral lateral condyle and 1 tibial plateau.Three types pure cartilage fracture were observed,totally defect of the cartilage in 7 sites(include 3 patella,2 femoral medial condyle,1 femoral lateral condyle and 1 tibial plateau),fissuring fracture in 3 sites(include 2 femoral medial and 1 femoral lateral condyles), superficial defect of the cartilage in 17 sites(include 5 patella,3 femoral medial and 9 femoral lateral condyle).Corpus liberum was found in 21 patients'knee joints by arthroscopy,but only 3 cases by MRI. Bone bruise was detected,and subcartilage low signal lines were normal.Conclusion Using FLASH-FS- T_1WI,SE-T_1WI,FISP-3D-FS-T_2WI and ME-T_2WI sequences,sagittal and coronal MRI scanning in femoral and tibial plateau pure cartilage fractures,and using ME-T_2WI sequence axial scanning in patella r cartilage fractures may show the position,extension and types of the acute pure cartilage fracture of the knee joint. MRI is the hest non-invasive method for studying cartilage fracture.

OBJECTIVEThis study aimed to evaluate the diagnostic value of a 24-hour esophageal combined multichannel intraluminal impedance pH (24 h our MII-pH) monitoring in children with gastroesophageal reflux (GER) disease and recurrent pneumonia.

METHODSA total of 17 cases with a suspected diagnosis of GER disease children with unexplained recurrent pneumonia underwent a 24-hour MII-pH monitoring to analysis of the nature and characteristics of reflux.

RESULTSIn the 17 cases of GER disease with recurrent pneumonia, 11 (65%) were confirmed positively by a 24-hours of MII-pH monitoring. A total of 853 reflux cycle were detected, of which 65.3% were acid refluxes predominantly occurring within 2 hours after meal, and 71.6% were mixed refluxes. Refluxes occurred most frequently in the supine position, followed by the lateral position and the prone position. Distal reflux was the predominant form of reflux. According to the Biox-Ochoa classification, 73% of cases (8/11) were severe GER.

CONCLUSIONSMII-pH monitoring may effectively characterize refluxate properties and thereby increase the detection rate of GER disease.
