Objective:To investigate the modulating effects of anti-epidermal growth factor monoclonal antibody Cetux- imab(C225)on the ehemosensitivity and radiosensitivity in a Docetaxel-resistant human lung adenocarcinoma cell line SPC-A-1/doeetaxel.Methods:Radiosensitivity of SPC-A-1/docetaxel was determined by clone formation experiment and quantified by calculating the enhancement ratio(ER).The growth inhibition of SPC-A-1/docetaxel cell line caused by C225 or combination of C225 and Docetaxel in different orders was detected by MTT assay.The effect of C225 on cell cy- cle distribution and apoptosis was determined by flow cytometry.Results:C225 combined with radiation significantly de- creased the number of the cell clones than radiation alone;the D_0 values were 1.73 Gy for the former and 2.39 Gy for the latter,and the enhancement ratio was 1.38.C225 alone at concentration up to 1000?g/ml for 48h had neither cytotoxic nor eytostatie effect on SPC-A-1/docetaxel in vitro.C225 administration followed by Docetaxel significantly decreased the ICw of Docetaxel(85.2?g/ml vs 128.7?g/ml).Flow cytometry demonstrated that C225 exposure induced apoptosis of SPC-A-1/docetaxel cells in a time-dependent manner.The cell in the G_0/G_1 fraction increased from(43.80?4.46)% to (60.50?6.57)%(P

OBJECTIVETo discriminate and determine of the artificial bear bile of the compound bile capsule.

METHODTaking the pharmacopoeia as reference, the artificial bear bile was discriminated and determined by HPLC.

RESULTThe compound bile capsule and the control sample had chromatographic peak at the same time from HPLC. The content of the artificial bear bile was above 10 mg per tablets.

CONCLUSIONThe artificial bear bile of compound bile capsules can be discriminated effectively and determined accurately by HPLC method.

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.

In order to study the contraindications of the compatibility of Flos Genkwa-Radix et Rhizoma Glycyrrhizae, in this study, the solubilizing and poisoning essence were explored. In this experiment, chromatographic assay, field emission scanning electron microscopy, MTT cytotoxicity evaluation, and other methods were used to study the main chemical components, morphology and toxicity of the ethyl acetate part of Flos Genkwa and its co-decoction with glycyrrhizic acid, in order to clarify Flos Genkwa-Radix et Rhizoma Glycyrrhizae incompatibility provides a new idea for the research on incompatibility of Flos Genkwa-Radix et Rhizoma Glycyrrhizae. The results showed that after co-decoction of the ethyl acetate part of Flos Genkwa with glycyrrhizic acid, high performance liquid chromatography (HPLC) detected the dissolution of the toxic component yuanhuacine of 54.8%, while yuanhuacine chromatographic peak was not detected in the Flos Genkwa ethyl acetate part of the single decoction. The increase of co-decoction dissolution rate was observed by scanning electron microscopy, and it was found that glycyrrhizic acid uniformly dispersed the fat-soluble components of Flos Genkwa into nano-scale particles, which improved the solubility and stability in the solution. Furthermore, the results of cytotoxicity evaluation showed that the survival rate of cells decreased after co-decoction, 4',6-diamidino-2-phenylindole (DAPI) staining also gave the same results. In summary, the co-decoction of the ethyl acetate part of Flos Genkwa with glycyrrhizic acid promotes the dissolution of the toxic component yuanhuacine, and makes the part form uniformly distributed nanoparticles, which is conducive to the absorption of the ingredient and increases the toxicity.

OBJECTIVETo explore the effect of Danshensu on the lipid metabolism of hyperlipidemic rats.

METHODSixty clean male SD rats were selected. Twelve of them were selected in the basic control group and fed with common foods, and the remaining rats were fed with the high-fat feeds. After the successful modeling, they were randomly divided into the high-fat control group and low dose (10 mg x kg(-1) x d(-1)), medium dose (20 mg x kg(-1) x d(-1)) and high dose (40 mg x kg(-1) x d(-1)) Danshensu (dissolved in saline) groups. Both of the two groups were abdominally injected with the same volume of normal saline once a day for consecutively 30 days. The serum TG, TC, HDL-C and liver ACC1, FAS, HMGR, CPT-I mRNA expressions were detected.

RESULT AND CONCLUSIONDanshensu could inhibit the LDL-C level, timely clear redundant cholesterol and effectively regulate the lipid metablism of hyperlipidemic rats by reducing the TC content, decrease the fatty acid by reducing the FAS mRNA expression, and reduce the synthesis levels of endogenous cholesterol by inhibit the HMGR mRNA expression.

Objective: To observe the effectiveness and safety of electroacupuncture (EA) plus Luohua Anshen oral liquid for patients with perimenopausal insomnia. Methods: A total of 66 participants who met the inclusion criteria were enrolled in the randomized controlled trial and allocated to a treatment group and a control group at a ratio of 1:1, with 33 cases in each group. Both groups were given Luohua Anshen oral liquid as a basic treatment. The treatment group was additionally given EA every other day, three times a week. Both groups were treated for four weeks and a four-week follow-up was conducted. The scores of Pittsburgh sleep quality index (PSQI), Kupperman index (KI) and traditional Chinese medicine sleep syndrome scale (TCMSSS) were recorded at pre- and post-treatment, and at the follow-up. Meanwhile, adverse effects were monitored and recorded. Results: After four-week treatment, the global scores of PSQI, KI and TCMSSS in both groups declined significantly (all P<0.05), and the decreases in the treatment group were more significant than those in the control group (allP<0.05). The global scores of PSQI, KI and TCMSSS in both groups at the follow-up visit were significantly different from the corresponding baseline (allP<0.05), while insignificantly different from those assessed at post-treatment (allP>0.05). The total effective rate was 93.9％ in the treatment group, significantly higher than 72.2％ in the control group (P<0.05). No significant adverse event was reported in this trial excepted one patient experienced slight dizziness in the first acupuncture treatment. Conclusion: EA plus Luohua Anshen oral liquid is safe for perimenopausal insomnia with satisfactory short- and long-term effectiveness, and it shows certain advantage compared with using Luohua Anshen oral liquid alone.
