Chinese Traditional and Herbal Drugs 2016;47(22):3975-3981
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.

Objective To investigate the relationship between proteinuria components and the severity of pregnancy induced hypertension syndrome (PIH), the unconcentrated urine samples from patients with PIH were analyzed on proteinuria components by electrophoresis.Methods Proteinuria components were analyzed by sodium dodecyl sulfate-agarose gel electrophoresis (SDS-AGE) in unconcentrated urine samples from PIH patients (PIH group,n=114) and normal third trimester pregnant women (control group,n=110).Results Eleven kinds of urinary protein were detected in the PIH group and four in the control group. The results showed positive relationship between the urine protein component complexity and the severity of PIH (P

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.

Background: Myoclonic epilepsy with ragged-red fi bers (MERRF) is a type of mitochondrial
encephalomyopathy, clinical experience with the antiepileptic treatment for myoclonus in MERRF is
still limited. Myoclonus appears to be intractable, and some antiepileptic drugs may change the blood
lactate level. Objective: In this study, we report on two patients, a girl and her mother, both with
MERRF in a Chinese family. We aimed to study their myoclonus attack, response to AEDs and blood
lactate level. Methods: The diagnosis was based on muscle biopsies and a genetic test. We recorded
their myoclonus and detected alterations of blood lactate when the patients received antiepileptic
drugs. Results: The patients displayed substantial differences in their responses to antiepileptic drugs.
The mother exhibited a good response to valproic acid, although valproic acid is not recommended
for mitochondrial disease; however, her daughter was refractory to many antiepileptic drugs until
she received a combination treatment of levetiracetam and topiramate. We did not fi nd valproic acid,
levetiracetam or topiramate affected the blood lactate levels.
Conclusion: These fi ndings imply that not all MERRF patients are resistant to antiepileptic drugs, and
for those who are intractable, combination treatment involving levetiracetam and topiramate may be
effective for treating myoclonus in MERRF and does not worsen lactic acidosis.
