Objective To evaluate the clinical efficacy of cutaneous scraping and cupping therapy for the treatment of hyperplasia of mammary glands. Methods Eighty patients with hyperplasia of mammary glands were randomized into test group(42 cases) and control group(38 cases). Both groups were given conventional basic treatment including psychological counseling and oral use of Chinese patent medicine, and the test group additionally received cutaneous scraping and cupping therapy on acupoints of Xuanji(CV21), Danzho ng (CV17), Jianjing(GB21), Kufang(ST14) , Tianzhong(SI11), Dazhui(GV14), and Ashi(focus of mammary mass and pain). The scores of pain visual analog scale(VAS) and World Health Organization Quality of Life Scale Brief Version(WHOQOL-BREF) were observed, and the clinical efficacy of the two groups was evaluated. Results (1) The total effective rate of the test group was 88.10%, and that of the control group was 65.79%, the inter-group difference being statistically significant (P<0.01). (2) After treatment, VAS scores of the test group were decreased obviously(P<0.01), and the control group showed a decreasing trend(P>0.05). Test group had better effect on improving VAS scores than the control group(P<0.05).(3) After treatment , the scores in physiological dimension of WHOQOL-BREF were much increased(P<0.05), and the changes in the scores of other dimensions were not obvious(P>0.05). The control group showed no obvious changes in the scores of each dimension of WHOQOL-BREF before and after treatment(P>0.05). The inter-group comparison showed that the test group had better effect on improving the scores in physiological dimension of WHOQOL-BREF (P<0 . 05). Conclusion Cutaneous scraping and cupping therapy is effective on relieving pain and improving QOL of patients with hyperplasia of mammary glands.

Objective To screen extraction process for Rosae Laevigatae Fructus.Methods With the content of total saponins and total phenolic acids from Rosae Laevigatae Fructus as the evaluation indexes, ethanol concentration, extraction time, solid-liquid ratio and extraction times as investigation factors, the test data were analyzed by Design-Expert8.0.5 software, and a multiple quadratic regression equation was set up to screen extraction process parameters of Rosae Laevigatae Fructus.Results The best extraction process parameters of Rosae Laevigatae Fructus were as follows:ethanol concentration was 62.79%;solid-liquid ratio was 13.12:1;the extraction time was 137.93 min;extraction times were 1.85 times. Considering the convenience for actual operation and the practicability of industrial production, the extraction process parameters should be ethanol concentration of 60%, revised solid-liquid ratio of 13:1, 2 hours' extracting time, and 2 extraction times.Conclusion Final selected parameters provide the basis for the extraction process of Rosae Laevigatae Fructus.

OBJECTIVE:To study the influential factors related to efficacy of Peach kernel-Rheum palmatum couplet medi-cines in TCM formula,and to reveal the general regularity of compatibility environment,common ratio,processing variety and dosage forms of P. kernel-R. palmatum couplet medicines. METHODS:Using Chinese Medical Prescription Selected Dictionary ed-ited by Peng Huairen as data source,142 formulas of P. kernel-R. palmatum couplet medicines were collected. By establishing data-base,compatibility types of P. kernel-R. palmatum couplet medicines,as well as common ratio,processed prodact,dosage form were classified statistically. The influential factors related to efficacy of P. kernel-R. palmatum couplet medicines with different pro-portions were summarized. RESULTS:The efficacy of P. kernel-R. palmatum couplet medicines could be divided into 6 aspects and 11 roles,including activating blood circulation to dissipate blood stasis(activating blood to relieve pain,promoting blood circula-tion to eliminate disease,activating blood to promote menstruation,breaking stagnant and eliminating blood stasis),eliminating carbuncle and detoxicating(cleaning intestine and clearing away the pathogenic heat of lung,eliminating carbuncle and expelling pus,eliminating sore and detoxicating),expelling the pathogenic heat to loosen the bowels,warming yang for dispelling cold,forti-fying the spleen and nourishing the stomach,relaxing tendon and activating blood. The compatibility environment of P. kernel-R. pal-matum couplet medicines were mainly compatible with TCM for activating qi to eliminate stasis,activating blood to promote menstru-ation,breaking stagnant and eliminating blood stasis,expelling the pathogenic heat to expel stasis. The ratio of P. kernel to R. palma-tum ranged 1 : 8-4 : 1,and the ratio ranged 1 : 8-3 : 1 when performing the role of actirating blood circalation to dissipate blood stasis. Common processed products were crude P. kernel and prepared R. palmatum. Common dosage forms were mainly decoction,pill and powder. CONCLUSIONS:Compatibility environment,ratio,processing varieties,dosage forms influence the effects of P. kernel-R. palmatum couplet medicines,especially compatibility environment.

In this study, we explored the feasibility of biotin-mediated modified polymeric micelles for pancreatic cancer targeted photodynamic therapy. Poly (ethylene glycol)-distearoyl phosphatidyl ethanolamine (mPEG2000-DSPE) served as the drug-loaded material, biotin-poly(ethylene glycol)-distearoyl phosphatidyl ethanolamine (Biotin-PEG3400-DSPE) as the functional material and the polymeric micelles were prepared by a thin-film hydration method. The targeting capability of micelles was investigated by cell uptake assay in vitro and fluorescence imaging in vivo and the amounts of Biotin-PEG-DSPE were optimized accordingly. Hypocrellin B (HB), a novel photosensitizer was then encapsulated in biotinylated polymeric micelles and the anti-tumor efficacy was evaluated systemically in vitro and in vivo. The results showed that micelles with 5 mol % Biotin-PEG-DSPE demonstrated the best targeting capability than those with 20 mol % or 0.5 mol % of corresponding materials. This formulation has a small particle size [mean diameter of (36.74 ± 2.16) nm] with a homogeneous distribution and high encapsulation efficiency (80.06 ± 0.19) %. The following pharmacodynamics assays showed that the biotinylated micelles significantly enhanced the cytotoxicity of HB against tumor cells in vitro and inhibited tumor growth in vivo, suggesting a promising potential of this formulation for treatment of pancreatic cancer, especially those poorly permeable, or insensitive to radiotherapy and chemotherapy.
