Objective: Using the improved volatile oil extractor to extract the essential oil of Caryophylli Flosand emulsified fragrance water. To research the correlations of the emulsified fragrance water from different condensing temperature and different temperature with the physicochemical parameters under the different temperature of essential oilin Caryophylli Flos;The results help a lot for the optimization of extraction process parameters of essential oil in Caryophylli Flos. Methods: Using surface tension tester, determination of viscometer to measure viscosity, surface tension, interfacial tension under different temperature of essential oil density in Caryophylli Flos, using stability analyzer to determine the emulsified fragrance water stability within 1 h and particle sizeunder different extraction temperature and different collecting temperature. Using multivariate data analysis to research the relationship between the essential physical and chemical parameters with emulsified fragrance water stability.Results: Relativedensity, viscosity, and surface tension reduced as the temperature of essential oil in Caryophylli Flos increased gradually, interfacial tension with increased first and then decreased as temperature increased. Turbiscan Stability Index(TSI) of the volatile oil emulsified fragrance water was negative correlation with the condensation temperature and interfacial tension, and was positive correlation with collecting temperature, density, viscosity, and surface tension. Conclusion: During the extraction process, temperature, interfacial tension, and condensation temperature of volatile oil in Caryophylli Floswere collected with aromatic water, and TSI hascertain relevance. Through controlling the collected temperature, condensation temperature, interfacial tension, and oil/water separation speed of volatile oil emulsified fragrance water have been changed and the guidance to the extraction process has been provided.

Objective To study the clinical and pathologic features,histological criteria and pathologic factors contributing to diagnosis of mixed epithelial and mesenchymal tumors(mixed m?llerian tumors,MMT)of the uterus.Methods A retrospective study of 102 cases of MMT of the uterus (74 adenofibromas including 9 recurrent cases,3 atypical polypoid adenomyomas,2 carcinofibromas,10 adenosareomas and 13 carcinosarcomas)was undertaken.Clinical records,gross features and tissue slices were reviewed.The follow-up data were analysed.Results The most common symptom was vaginal bleeding.Clinical signs included pelvic mass,uterine polyps,and enlarged uterus.Benign MMT usually presented as exophytic polypoid masses extending into the uterine cavity or protruding through the external os,often broad-based,lobulated and papillary.It was hard to distinguish low-grade malignant MMT from the benign ones by gross appearance.High-grade malignant MMT had the common gross features of carcinoma and sarcoma.Histologically,MMT showed a biphasic differentiation of mesenchymal and epithelial components.MMT were classified according to whether these elements were benign or malignant.Nine cases of adenofibroma without unique features for the diagnosis of adenosarcoma recurred at postoperative intervals of 3 to 96 months.Recurrent tumors were almost always confined to the original site.Conclusions Uterine MMT tumors according to WHO diagnostic criteria are not rare.The differential diagnosis depends on a multifactorial analysis.The recurrent adenofibromas may be a kind of borderline tumors with benign appearances and malignant behavior.

Objective To explore the clinical and MR imaging features of myxoid liposarcoma.Methods Clinical and MR imaging data of 7 patients with histologically confirmed myxoid liposarcomas on extremities were retrospectively analyzed.The age of the patients ranged from 41 to 59 years with a median age of 51 years.Results Three tumors occurred in thigh,two in calf,one in foot and one in shoulder.Six tumors were situated deeply,and one was superficial.On T_1-weighted images,all 7 tumors showed predominant isointense or slightly hypointense signals relative to muscle,with 6 having lacy,linear or amorphous loci of high signal intensity.The major portion of each tumor displayed hyperintense signals compared with fat on T_2-weighted images.Following the injection of Gd-DTPA,all tumors showed inhomogenous and strong enhancement.All tumors had septa and were well defined without obvious surrounding edema and invasion of the adjacent bones.Conclusion Myxoid liposarcomas usually show predominant isointense or slightly hypointense signals relative to muscle on T_1-weighted images and hyperintense signals relative to fat on T_2-weighted images.The fat components within the tumors may be identified as linear,lacy or amorphous foci of high signal intensity on T_1-weighted images.The contrast enhancement of the mvxoid liposarcomas is usually pronounced and heterogeneous.

Age-related macular degeneration(AMD), the most common cause of irreversible blindness over 50 years in developed countries, is a degenerative disease occurs with age. The prevalence rate in our country is also increasing by year and the pathogenesis is still undiscovered. In this review, we focus on the associated risk factors reported in recent years, aim to further understand the pathogenesis of AMD.

ObjectiveTo observe the curative effect of the Chinese traditional medicine combined with traction and physical therapeutic on lumbar intervertebral discprolapse (LIDP).Methods95 LIDP patients were randomly divided into the treatment group (50 cases) and control group (45 cases). Patients of the treatment group were treated by Chinese traditional medicine, traction and physical therapy. Patients of the control group were treated by traction and physical therapy only.ResultsThe total clinical effective rate of the treatment group was 100%, but that of the control group was 75.6%, there was a significant difference between two groups (P<0.05).ConclusionChinese traditional medicine therapeutics is an effective non-surgical therapeutics for LIDP.

Xanthine oxidase (XOD), catalyzing purine metabolism, is the key enzyme in uric acid (UA) biosynthesis, and becomes an important target for hyperuricemia treatment. The inhibition on XOD plays an important role in the treatment of hyperuricemia-related diseases, such as gout, as well as oxidative stress-induced tissue injury. Here, studies on the natural products with XOD inhibition are reviewed.
