This study is aimed to establish a high-performance liquid chromatography (HPLC) method for simultaneous determination of skimmin, scopolin and umbelliferone in Saussurea hieracioides. Samples were analyzed on a Wondasil C18-WR column (4.6 mm x 250 mm, 5 microm) with methanol (A) and water containing 0.1% phosphate (B) as mobile phases for gradient elution at a flow rate of 1.0 mL x min(-1). The detection wavelength and column temperature were set at 325 nm and 35 degrees C, respectively, and the sample size was 10 microL. The results showed that skimmin, scopolin and umbelliferone were simultaneously achieved within 40 min under the above conditions. A good linearity was observed in the range of 0.18-5.6 microg (r = 1.000 0), 0.060-1.8 microg (r = 0.999 9), 0.032-0.97 microg (r = 0.999 8) for skimmin, scopolin and umbelliferone, respectively, with the average recoveries of 99.16% (RSD = 0.41%), 100.3% (RSD = 0.79%), 102.2% (RSD = 0.87%). The method is simple, accurate and reproducible and can be used for the quality control of S. hieracioides.

Objective To investigate the feasibility of a new polyclonal antibody specific to fetal hemoglobin (HbF) and its application in enrichment of circulating fetal nucleated red blood cell(NRBC) for non-invasive prenatal diagnosis. Methods A polyclonal antibody against a synthetic peptide comprising residues 69-78 of the γ-chain of HbF was prepared and conjugated to carrier protein KLH as the immunogen according to the specific antigenic determinant. The peptide-KLH solution was mixed with freund's complete or incomplete adjuvant and immunized goat to prepare specific polyclonal antibody against the γ-chain of fetal hemoglobin. After purification with protein G, maternal blood was obtained from 32 pregnant women at 22 to 39 weeks of gestation. NRBCs were separated and then stained with antibody against the γ chain of HbF. All the positive cells were collected by micromanipulator under microscopic observation, and whole genome was amplified by improved primer extension preamplification (PEP). Multiplex polymerase chain reaction amplification at nine different polymorphic short tandem repeat (STR) loci was also used to determine origin of the positive cells isolated from maternal blood. Results NRBCs stained with antibody against the γ chain of HbF were found in all of the blood from the 32 cases. Attached positive cells with anti-HbF staining have unique morphological characteristics, low nucleus-to-cytoplasm ratio, brown cytoplasm and blue dense nucleus after hematoxylin counterstain under microscopic observation, which can distinguished NRBCs with other cells. A total of 183 NRBCs were found in all of 32 pregnant women at a range of 0.6~1.8 cell/ml venous blood. The accurate rate was 90.6% by the STR genotype identification. Conclusion The antibodies specific to fetal γ-chain of fetal hemoglobin with synthetic peptide technology may have wide clinical utility in identification of fetal NRBCs from maternal circulation for non-invasive prenatal genetic diagnosis.

Background: Acute mastitis is an acute infectious disease of breast. Antibiotic treatment is often unable to obtain a good effect, and we should actively look for a safe and effective non-drug therapy. Objective: To validate the clinical efficacy of kneading and dispersing manipulation in treatment of early-stage acute mastitis. Design, setting, participants and interventions: According to the multicenter randomized controlled trial design, 198 cases of acute mastitis from Yueyang Hospital of Integrated Traditional Chinese Medicine, Longhua Hospital, and Shanghai Yangpu Maternity and Child Health Hospital were randomly divided into treatment group and control group. There were 99 cases in each group. Patients in the treatment group were only treated with manipulation, and cefradine was orally administered to patients in the control group. Main outcome measures: The local breast lump size, clinical symptoms and the adverse reactions in the two groups were observed before and after the treatment. Results: The total response rates in the treatment and control group were 95.92% (94/98) and 80% (76/95) respectively. There was a significant difference in the total response rate between the two groups (P<0.05). There were significant differences in the score of breast lump size, and the score of signs and symptoms between the two groups (P<0.05). Conclusion: Kneading and dispersing manipulation has certain effects on early-stage acute mastitis, and the therapy is safe and repeatable.
