Objective To study anti-inflammatory and analgesic effects of extract from the roots and leaves of Citrulluslanatus and assess their acute toxicity in animals.Methods The mouse model with ear edema induced by xyleneand the rat model with paw edema or granuloma by carrageenin or cotton pellet were used for anti-inflammatoryeffects of the extract.Effects of the extract on analgesia was tested respectively by measuring the latency of micelicking hind foot from hot plates and by counting the times of body twisting in response to acetic acid.The acutetoxicity of the extract was determined with the method of Bliss.Results The extract significantly inhibited the earedema,granuloma hyperplasia,and paw edema.It significantly lifted the pain threshold on mouse hot-plateresponses and reduced their writhing times.During the 7 d observation period in its acute toxicity assay,no apparenttoxic reaction was shown and all mice survived at a dose of 87 g extract per kg body weight.Conclusion Theextract could protecte mice/rates from inflammation and analgesia,and may be safe as an orally administered naturalproduct for humans.

This study was aimed to reveal the medication patterns of Chinese patent medicine in the treatment of breast hyperplasia based on association rules and clustering of data mining technology. Articles on Chinese patent medicine in the treatment of breast hyperplasia were retrieved from databases. External formulas or those mixed with western drugs were excluded. Terminologies in the selected formulas were standardized. Information was extracted to build excelltables. Association rules analysis and cluster analysis were used to reveal the medication patterns of Chi-nese patent medicine in the treatment of breast hyperplasia with software R2.15.2 and Cytoscape 2.8.3. The results showed that Chinese medicinals with higher frequency in 195 formulas were Radix bupleuri, Rhizoma cyperi, Chinese Angelica, Selfheal, White Peony Root, Trichosanthes kirilowii Maxim et al. Chinese medicinals with lower frequency were Chinese Alangium leaf, Rhinacanthus nasutus et al. The commonly used herbal pairs were Radix bupleuri -Chinese A ngelica, Rhizoma curcumae - Rhizoma sparganii, frankincense - myrrh et al. The strong association rules indicated that Xiaoyaosan, which takes Radix bupleuri and Chinese A ngelica as its core, is the key character of Chinese patent medicine in the treatment of breast hyperplasia. The cluster analysis revealed several Chinese medicine functional modules, such as Fructus forsythiae - Rhizoma smilacis glabrae - Evodia lepta - Chinese mahonia stem - Lignum millettiae et al. It was concluded that the herbal frequency, herbal pairs, strong associa-tion rules and cluster analysis can reveal the medication patterns of Chinese patent medicine in the treatment of breast hyperplasia in order to provide reference evidences in the optimization of clinical treatment for mula and im-provement of therapeutic efficacy.

OBJECTIVE: To investigate the clinopathological characteristics, differential diagnosis, therapy and prognosis of sinonasal mucosal malignant melanoma. METHOD: Clinopathological data of 18 cases which were diagnosed by pathology and immmunohistochemistry were analyzed retrospectively. All cases were proved by pathology and immmunohistochemistry. All cases were performed operations. 5 underwent single surgery. 4 underwent surgery plus adjuvant radiotherapy. 4 underwent surgery plus adjuvant radiotherapy chemotherapy. 5 underwent surgery plus adjuvant chemoradiation. RESULT: All cases were followed up for a period of 1 to 7 years after operation. Twelve patients died of tumor until the last follow-up, meanwhile 6 patients stayed alive. In Six cases recurrence occurred. In five casescervical lymph node metastasis occurred, of which 3 cases received neck dissection and 2 cases received chemotherapy and radiotherapy due to no surgical indications. In three cases distant metastasis oc- curred. CONCLUSION Sinonasal mucosal malignant melanoma is rare and highly heterogenous. Current diagnosis depends on clinical characteristics and immunohistochemical examination. It still should be differentially diagnosed from other tumors. CT and MRI image examination can provide some helpful information to understand the extent and nature of lesions. The treatment of nasal endoscopic or the surgery under endoscopy has become to be a safe, viable and reasonable alternative to open resection. Appropriate indication must be carefully selected for these lesions.

Cardiovascular diseases are the leading cause of death in the world today. Atherosclerosis （AS） is a chronic inflammatory disease characterized by thickening or functional degeneration of the arterial wall， and in the later stage of the disease， plaque ruptures to induce thrombosis， which in turn causes ischemia in tissues or organs. It is therefore the pathological basis for all types of cardiovascular diseases. Nuclear transcription factor kappa B （NF-κB）， an important nuclear transcription factor in the inflammatory response， is activated to mediate the transcription of inflammatory factors that can trigger or exacerbate the development of AS. Vascular endothelial cells are activated by inflammatory factors. NF-κB mediates related regulatory genes in endothelial cells to secrete adhesion molecules， chemokines， and coagulation factors， promotes selective aggregation of monocytes， up-regulates the expression of adhesion molecules to make adhesion molecules stick to the endothelium and move toward the intima， promotes the degradation of the extracellular matrix， and forms unstable plaques. In recent years， traditional Chinese medicine （TCM） has achieved certain results in the prevention and treatment of AS， and many Chinese medicines have been proved to be effective in resisting AS and can act on multiple targets in the human body， affecting the occurrence and development of AS in different links. This paper mainly introduced the NF-κB pathway and its relationship with AS， reviewed research progress on 75 components of different types in Chinese medicine monomers such as flavonoids， terpenoids， and alkaloids in AS resistance based on the NF-κB pathway， and found that Chinese medicine monomers mainly regulate cholesterol balance， inhibit the inflammatory response， reduce cell proliferation， inhibit intercellular adhesion， and suppress foam cell formation by regulating the NF-κB pathway to provide a reference for the prevention and treatment of AS.
