Antimicrobial peptides (AMPs) are small molecules produced by a myriad of cells and play important roles not only in protecting against infections and sustaining skin barrier homeostasis but also in contributing to immune dysregulation under pathological conditions. Recently, increasing evidence has indicated that AMPs, including cathelicidin (LL-37), human β-defensins, S100 proteins, lipocalin 2, and RNase 7, are highly expressed in psoriatic skin lesions. These peptides broadly regulate immunity by interacting with various immune cells and linking innate and adaptive immune responses during the progression of psoriasis. In this review, we summarize the recent findings regarding AMPs in the pathogenesis of psoriasis with a main focus on their immunomodulatory abilities.

The mutations in the dual oxidase 2 (DUOX2) and dual oxidase maturation factor 2 (DUOXA2) genes can cause congenital hypothyroidism (CH). This study reports the pedigree with goitrous congenital hypothyroidism (GCH) due to the coexistence of heterozygous mutations in the DUOX2 and DUOXA2 genes. The two sisters with GCH were diagnosed with CH at neonatal screening and were enrolled in this study. The DUOX2, DUOXA2, and thyroid peroxidase (TPO) genes were considered for genetic defects screening. Family members of the patients and normal controls were also enrolled and evaluated. The two girls harbored compound heterozygous mutations, including a new mutation of c.2654G>T (p.R885L) in the maternal DUOX2 allele and c.738C>G (p.Y246X) in the paternal DUOXA2 allele, that has been previously reported. The germline mutations from the families were consistent with an autosomal recessive inheritance pattern. No mutations in the TPO gene and the controls were observed.

OBJECTIVETo investigate clinical results of AO clavicular hook plate for the treatment of fresh Tossy type III acromioclavicular joint dislocation.
METHODSFrom December 2006 to December 2008, 28 patients with fresh Tossy type III acromioclavicular joint dislocation were treated with AO clavicular hook plates. There were 23 males and 5 females. The average age at surgery were 46.4 years (ranged, 22 to 68 years). The average time from suffering injuries to the operation was 3.9 days(ranged, 1 to 21 days). And the average time from the operation to plate removal was 9.4 months(ranged, 6 to 22 months).
RESULTSAll the patients were followed up, the duration ranged from 6 to 24 months, with an average of 15 months. There was 1 patient with traumatic arthritis, 1 patient with plate fracture. And the others had good results without fracture and re-dislocation after operation. According to Karlsson standards, 21 patients got an excellent result, 6 good and 1 poor. Eight patients had pain and restricted activities in shoulder joints before the plate removal, and all the symptoms were catabatic after removing the clavicular hook plates. After exercise, the function of the shoulder joints achieved normal level.
CONCLUSIONClavicular hook plate used for the fresh Tossy type III acromioclavicular joint dislocation has advantages such as simple operation, little wound, less blood loss and early exercises.

OBJECTIVETo determine the number of goblet cells, the change of MUC5AC expression in chronic obstructive pulmonary disease (COPD) patients and the relationship of smoking with goblet cell, MUC5AC, and lung function.
METHODSEighteen patients undergoing lung resections for a solitary peripheral carcinoma were classified by lung function as having COPD. Twenty patients with normal lung function served as the control group. Normal lobe bronchioles far away from the lesion site were taken for paraffin section. Goblet cells were identified by AB/PAS staining and the expression of MUC5AC in the paraffin's section was tested by immunohistochemistry.
RESULTSGoblet cell hyperplasia was observed in the COPD group. The positive rate of goblet cell in COPD group (0.20% +/- 0.10%) was significantly higher than that in the normal lung function group (0.13% +/- 0.06%, P < 0.05). The positive rate of MUC5AC expression in the COPD group (0.27% +/- 0.09%) was higher than that in the normal lung function group (0.20% +/- 0.10%, P < 0.05). The positive rate of goblet cell in smokers (27.93% +/- 9.00%) of the COPD group and normal lung function group was higher than that in non-smokers (17.70% +/- 9.37%, P < 0.05), while MUC5AC expression had no significant difference between smokers and non-smokers (17.88% +/- 6.44% and 10.88% +/- 7.10%, respectively).
CONCLUSIONFor COPD patients with declined lung function, there were goblet cell hyperplasia and increased expression of MUC5AC. MUC5AC expression up-regulation may due to goblet cell hyperplasia. Smoking may be an important factor for goblet cell hyperplasia.

AIMThe anti-gastric ulcer constituents from the roots of Crepis napifera (Franch) Babc (Compositae) were studied.
METHODSSolvent partition, Si gel and Rp-18 column chromatography, crystallization and spectral methods were used to extract, isolate and identify two compounds. The activity of compound 1 was tested on the rat stomach by determining the effect on aspirin-induced gastric lesions and on histamine-stimulated gastric acid secretion.
RESULTSTwo sesquiterpene lactone glycosides, taraxinic acid-1'-O-beta-D-glucopyranoside (1) and 11,13-dihydro-taraxinic acid-1'-O-beta-D-glucopyranoside (2) were obtained. Compound 1 at the dose of 80 mg.kg-1 p.o. inhibited significantly the development of aspirin-induced gastric lesions in the rat and at an i.v. dose of 70 mg.kg-1 did not affect histamine-stimulated gastric acid secretion in the lumen-perfused rat stomach.
CONCLUSIONCompound 1 is the active component of the plant which protects gastric mucosa and exhibits anti-gastric ulcer action.

OBJECTIVETo set up the HPLC fingerprints of different samples of processed Rhizoma Coptidi (RC) in order to offer evidence for identifying different processed RC and preliminary discussion on processing mechanism.
METHODSeven different samples of processed RC were determined by HPLC and the results were analyzed by Hierarchical clustering and similarity evaluation system for chromatographic fingerprint of TCM.
RESULTThe characteristic of common peaks for fingerprints of different samples of processed RC is distinct, but there are differences among various processed RC. The different samples of processed RC were classified into two and the result of hierarchical clustering is correlated with the property of traditional Chinese drug.
CONCLUSIONIt is proved that the method which is convenient, rapid and repeat well can be used to identify different samples of processed RC. The change of property of different processed RC is related with processing adjuvant, the possible mechanism is that new components are produced or the contents of known components have changed due to the adjuvant during processing.

OBJECTIVETo assess whether these characteristics of less misclassification and greater area under receiver operator characteristic (ROC) curve of the new injury severity score (NISS) are better than the injury severity score (ISS) as applying it to our multiple trauma patients registered into the emergency intensive care unit (EICU).
METHODSThis was a retrospective review of registry data from 2 286 multiple trauma patients consecutively registered into the EICU from January 1,1997 to December 31, 2006 in the Second Affiliated Hospital, Medical School of Zhejiang University in China. Comparisons between ISS and NISS were made using misclassification rates, ROC curve analysis, and the H-L statistics by univariate and multivariate logistic progression model.
RESULTSAmong the 2 286 patients, 176 (7.7%) were excluded because of deaths on arrival or patients less than 16 years of age. The study population therefore comprised 2 110 patients. Mean EICU length of stay (LOS) was 7.8 days ?2.4 days. Compared with the blunt injury group, the penetrating injury group had a higher percentage of male, lower mean EICU LOS and age. The most frequently injured body regions were extremities and head/neck, followed by thorax, face and abdomen in the blunt injury group; whereas, thorax and abdomen were more frequently seen in the penetrating injury group. The minimum misclassification rate for NISS was slightly less than ISS in all groups (4.01% versus 4.49%). However, NISS had more tendency to misclassify in the penetrating injury group. This, we noted, was attributed mainly to a higher false-positive rate (21.04% versus 15.55% for ISS, t equal to 3.310, P less than 0.001), resulting in an overall misclassification rate of 23.57% for NISS versus 18.79% for ISS (t equal to 3.290, P less than 0.001). In the whole sample, NISS presented equivalent discrimination (area under ROC curve: NISS equal to 0.938 versus ISS equal to 0.943). The H-L statistics showed poorer calibration (48.64 versus 32.11, t equal to 3.305, P less than 0.001) in the penetrating injury group.
CONCLUSIONSNISS should not replace ISS because they share similar accuracy and calibration in predicting multiple blunt trauma patients. NISS may be more sensitive but less specific than ISS in predicting mortality in certain penetrating injury patients.
