OBJECTIVETo detect the expression level of interleukin 17 (IL-17) in the plasma and colonic mucosa of patients with ulcerative colitis (UC), and to explore the synergistic mechanism of qingchang huashi recipe (QHR) combined with Mesalazine.
METHODSRecruited were 24 mild or moderate UC patients of damp-heat inner accumulation syndrome (DHIAS). Their samples of intestinal tissues were histologically graded. They were assigned to the combination group and the Western medicine (WM) group, 12 in each group. Besides, another 12 healthy volunteers were recruited as the healthy control group. QHR combined Mesalazine were given to patients in the combination group, while those in the WM group took Mesalazine. The therapeutic course for all was 3 months. By the end of treatment the expression level of IL-17 in the plasma and colonic mucosa was detected using ELISA. The infiltration of IL-17 in the intestinal mucosal tissue was detected by immunohistochemical SP method.
RESULTSThe expression level of IL-17 in the plasma and colonic mucosa was significantly higher in UC patients than in healthy controls (P <0. 05). The higher the histological grading the higher the expression level. The expression level of IL-17 in plasma and colonic tissues decreased after treatment in the two treatment groups (P < 0.05). Besides, the expression level of IL-17 was lower in the combination group than in the WM group (P <0.05).
CONCLUSIONQHR combined Mesalazine could synergically enhance the effect and effectively inhibit intestinal inflammation through down-regulating the expression of IL-17.

BACKGROUND: It is very important to explore an optimal loading force that can both allow effective intrusion and cause no damage to the teeth.OBJECTIVE: To investigate the optimal loading conditions, including loading force values and directions, in the intruding mechanics of maxillary anterior teeth.METHODS: A three-dimensional finite element model (3D FEM) of the maxillary anterior teeth was constructed to include the periodontal ligament (PDL), alveolar bone, and appliance (brackets and wire). The initial stress distribution and force of the maxillary anterior teeth were analyzed when the 3D FEM was loaded with different intruding force values and directions. RESULTS AND CONCLUSION: The optimal value of the intruding force for 6 anterior teeth fell within the range from 0.5 N to 1.0 N. The maximum stress was detected at the distal cervical level of the lateral incisor, and a relatively even distribution of initial stress was observed at 20° palatal deviation to the Y axis. The results suggest that using mini-screw implants at the labial region between the canine and lateral incisor and a combined 0.5-1.0 N intruding force with a distal force could be an optimal intrusion force system by which patients with normal occlusion could obtain a pure intrusion of anterior teeth.

Objective To investigate the genotype in Chinese patients with nonclassical 21 hydroxylase deficiency (NC 21OHD). Methods Eight patients with NC 21 OHD, 35 patients with classical one and 20 normal controls were studied as followed: CYP21 gene was amplified into fragment 1 (exon1→exon3) and fragment 2 (exon3→exon10) through PCR with specific primers. Second round PCRs were performed using fragment 1 and 2 as template, and PCR products were digested by restrictive endonucleases to analyze mutations by 3% 4% agarose gel electrophoresis. Results (1) The most frequent mutation in 8 cases of Chinese NC 21 OHD was P30L(6/16,37.5%), followed by V281L(4/16,25.0%). NC 21 OHD also carried mutations causing moderate or severe degree of enzymatic compromise, such as i2g (3/16, 18.8%), Q318X and R356W (1/16, 6.3% respectively), and I172N (3/16, 18.8%). (2) In ACTH 1 24 stimulation tests of 8 NC 21 OHD patients, basal 17 OH progesterone level was (23.9?28.4)?g/L and stimulated 17 OH progesterone level was (92.0?83.7)?g/L. (3) Genotype had strong correlation with phenotype in 21 OHD patients. Conclusion (1) As compared with caucasians, the most frequent mutation in Chinese NC 21 OHD is P30L, not V281L. (2) Much more attention should be paid to patients with hyperandrogenism to screen NC 21 OHD.
