OBJECTIVE: To investigate the distribution of positive allergens in patients with allergic rhinitis in Changzhou. METHOD: A total of 4242 cases with allergic symptoms and signs underwent skin prick test with 16 kinds of standardized allergens. The common allergens were found out. The samples were stratified on seven age groups to analysis the distributive characteristics of allergens responsible for each group. The samples were also stratified on children group and adults group to analysis their response degree to dust mite. RESULT: 2638 cases (62.19%) had the positive reaction, including male 1380 (52.3%) cases, female 1258 (47.7%) cases. Dermatophagoides farinae and dermatophagoides pteronyssinus had the highest positive ratio (85.86%, 83.55%) in inhalation group, followed cockroach (11.49%) and Humulus L. (9.82%), fungus (2.92%) in the lower positive ratio. Shrimp (5.76%) was the most common allergen in food group. The distribution of common allergens in different age groups was variable. There was significantly higher sensitivity to dust mite between children group compared to adults group (P < 0.01). CONCLUSION The study shows that Dust mite was the mostly responsible common allergen in Changzhou district. The distribution of common allergens in children group and adults group was variable.

Non-coding RNAs(ncRNAs) are special RNAs that they don't have protein coding function, but they can affect chromosome structure, gene transcription and participate in the processes of epigenetic modifications. ncRNAs include long non-coding RNAs, microRNA, etc. In recent years, it has been found that these ncRNAs can maintain bone remodeling by adjusting bone resorption and formation in osteoporosis(OP). In the future, it may be a key target of the drug action screening which is clarifying the regulatory mechanism of ncRNAs in the occurrence and development of OP. OP belongs to bone rheumatism category in traditional Chinese medicine, according to the theory of “the kidney generating marrow and dominating bone” in traditional Chinese medicine, kidney tonifying and bone strengthening formulas are used to treat the OP in clinic, and the curative effect is remarkable. It has been found that kidney tonifying and bone strengthening prescriptions can enhance the proliferation of osteoblasts or inhibit the differentiation of osteoclasts by up-regulating or down-regulating the expression of ncRNA, and finally maintain OP bone homeostasis, thus exerting therapeutic effect. However, the specific molecular mechanism is still in its exploratory stage. Therefore, this paper summarized the molecular mechanism of kidney tonifying and bone strengthening prescriptions regulating ncRNAs in the treatment of OP in recent years, in order to provide the new ideas for the screening of the key therapeutic targets of OP drugs and the prevention and treatment of OP with traditional Chinese medicine.
