ABSTRACT
<p><b>OBJECTIVE</b>To assess the efficacy and safety of topical tacrolimus for erosive oral lichen planus (EOLP).</p><p><b>METHODS</b>Literatures published up to December 2013 were searched from PubMed, Embase, CENTRAL, Chinese BioMedical Literature Database (CBM), and System for Information on Grey Literature in Europe (SIGLE). All randomized controlled trials (RCTs) of topical tacrolimus for EOLP which compared with other interventions or a placebo were considered in this Meta-analysis. Two researchers collected data independently. The assessment of methodological quality was based on Cochrane Handbook and the materials were analyzed with the software Revman 5.2.5. The primary outcome measures were the symptoms (e.g. pain, discomfort) complained by patients. The secondary outcome measures included the improvement rate of clinical signs assessed by the investigators and the incidence of adverse effects (e.g. clinical candidiasis).</p><p><b>RESULTS</b>A total of 9 RCTs involving 476 patients were finally included. The pooled odds ratio (OR) of clinical improvement for topical tacrolimus vs. topical corticosteroids was 1.19 [95% confidence interval (CI): 0.64-2.22, I2: 44%]. Regarding to 0.1% tacrolimus and 0.03% tacrolimus, the pooled OR were 1.87 (95% CI: 0.60-5.82) and 1.47 (95% CI: 0.14-16.04) respectively in subgroup analysis. No serious adverse events were reported in topical tacrolimus group.</p><p><b>CONCLUSIONS</b>There was no evidence to support that topical tacrolimus for EOLP was more effective and safer than topical corticosteroids in this Meta-analysis. Clinical assessment criteria should be established and accepted by clinicians and researchers before further RCTs are undertaken.</p>

OBJECTIVE: To investigate the expression of proteasome immunosubunit low molecular weight polypeptide (LMP)2 and LMP7 in labial glands of patients with primary Sjogren's syndrome patients, and thus explore their role in the diagnosis, differential diagnosis and pathogenesis of primary Sjogren's syndrome (pSS). METHODS: Labial specimens were collected from 40 patients with pSS, 15 patients with connective tissue diseases other than pSS, and 9 healthy controls. The expressions of LMP2 and LMP7 in labial specimens were determined using immunohistochemical approaches and analyzed using semi-quantitative methods. The positive rate of acinar was calculated. After the square arcsine transformation of data, the differences of the positive rate in acinar between LMP2 and LMP7 were compared among three groups. Spearman's rank correlation coefficient was used for analyzing the correlation of clinical manifestations with LMP2 and LMP7 expressions. RESULTS: The expressions of LMP2 and LMP7 within the acinar and ductal epithelial cells were confirmed. Although the LMP2 expression in labial specimens was not significantly different among three groups(P=0.369), the expression of LMP7 was significantly higher in pSS patients compared with patients with connective tissue disease and healthy controls (P<0.01). Only in pSS group, LMP7 was found to be with higher positive rate in acinar than LMP2 (P<0.01). No significant correlation was found between LMP2/LMP7 and clinical manifestations (P>0.05). CONCLUSION: In patients with pSS, the expression of LMP7 (but not LMP2) is up-regulated in labial gland, indicating these two proteins have different genetic regulation mechanisms.

<p><b>OBJECTIVE</b>To reveal malocclusion of primary dentition in the suburb of Chengdu.</p><p><b>METHODS</b>Cross-section survey and malocclusion rate calculation were performed.</p><p><b>RESULTS</b>There are 491 children with malocclusion from total 1 279 children; the rate of malocclusion is 38.38%. The most important malocclusion in primary dentition are over bite (III degrees), anterior cross bite, edge to edge bite, early loss of deciduous teeth, fused teeth.</p><p><b>CONCLUSION</b>The rate of malocclusion of primary dentition in the suburb of Chengdu is a little bit light. Much work should be done to prevent or treat the malocclusion of primary dentition.</p>
