Objective:To compare psychosocial factors and immune function between patients with breast cancer and benign tumor before operation.Methods:The patients of breast tumor(56 case)were measured by clinical psychological rating scale(EPQ、HAMD、HAMA、LES、SSRS、DSQ)before operation,and their serum levels of IgA, CD_4~+,CD_(19)~+ and the activity of NK cell were measured.The patients of breast tumor were divided into breast cancer group(36 case)and benign tumor group(22 case)bases on results of pathology.Results:In breast cancer group, there were significantly higher scores of neurotic,total and negative life events,immature defense styles,HAMA and HAMD than those in benign tumor group;while NK cell activity,levels of CD_4~+ and CD_(19)~+ and the score of mature defense,social supports,subjective supports and utility degree of supports were marked lower.There were significantly correlation between immune function(NK cell activity,content of CD_4~+,CD_(19)~+,IgA)and psychosocial factors(social support,P score of EPQ,HAMD and HAMA total score,quantity of negative life events etc). Conclusion:Cancer patients had more server psychosocial problems and lower immune function.The immune function of patient with breast cancer before operation is associated with the various psychosocial factors.

Membrane proteins are the main undertakers of biofilm function, and also the most important target group for innovative drug discovery and research. About 60% of drugs targets are membrane proteins. Due to the obvious aggregation and denaturation tendency of membrane proteins in aqueous solution, it is difficult to simulate the membrane like environment to maintain the correct conformation of membrane proteins in vitro, which results in the slower-growing research on the structure and function of membrane proteins and related ligand drugs than that of water-soluble proteins. Membrane protein stabilization technology is the premise of establishing high specificity, high sensitivity and high throughput drug screening methods for membrane protein ligands, which is of great significance. In this paper, some techniques for stable separation and purification of membrane proteins are reviewed, including detergents, artificial membranes, polymers, lentiviral particles and so on, as well as their specific applications in drug screening.

OBJECTIVETo discriminate Descurainiae Semen and Pantagirus Semen.

METHODA high-performance liquid chromatographic method was developed to establish the fingerprint of Descurainiae Semen, and hierarchical cluster analysis (HCA) and partial least squares discriminant analysis (PLS-DA) were applied to study HPLC fingerprinting and chemical recognition.

RESULTThere exists large difference of chromatographic peaks and its relative peak area of HPLC fingerprints between Descurainiae Semen and Pantagirus Semen, and after conducting statistical analysis, the result demonstrated that all samples were classified into three categories: Descurainiae Semen, Pantagirus Semen and their mixtures.

CONCLUSIONThe developed HPLC fingerprint combined with chemometrics can be utilized to discriminate between Descurainiae Semen and Pantagirus Semen, which was quick, simple, accurate and reliable an can provide the basis for the characterization and quality assess of Descurainiae Semen and Pantagirus Semen.

"Tinglizi", the ripe seed of Descurainia sophia and Lepidium apetalum, is a member of Brassicaceae (Cruciferae). Traditionally, the former is called "Nantinglizi" (Descurainiae Semen) while the latter is called "Beitinglizi" (Lepidii Semen). In the theory of traditional Chinese medicine, it has the power to purge lung-fire, relieve dyspnea, promote diuresis and reduce edema, and it is mainly indicated in a case with phlegm-fluid accumulation, cough with excessive sputum, dyspnea with being unable to lie, and general swelling. In view of its wide-spread application in clinic, a comprehensive review of Lepidii Semen and Descurainiae Semen was conducted from the following aspects: herbalogical study, variety identification, historical evolution of processing, chemical constituents, pharmacological effects, quantitative determination and toxicity which could provide reference for further research and development of "Tinglizi".

OBJECTIVETo compare the clinical efficacy differences between acupoint catgut embedding and Kuntai capsule for perimenopausal syndrome, so as to provide an effective treatment method for perimenopausal syndrome.

METHODSThirty-three cases in the embedding group were treated with acupoint catgut embedding at back-shu points and front-mu points of liver, spleen and kidney combined with syndrome differentiation and disease differentiation, ten days per times; the Kuntai group was treated with oral administration of Kuntai capsule, 4 capsules each time, three times per day. The Kupperman index (KI) was observed in the two groups before treatment after 10 days, 30 days and 60 days of treatment, respectively; the efficacy was evaluated according to the ratio of KI.

RESULTSAfter the treatment, as treatment proceeded, the score of KI and ratio of KI were gradually reduced in two groups; the score of KI and ratio of KI in the embedding group after 10 days of treatment was lower than those in the Kuntai group (both P<0.05); after 10 days of treatment, the total effective rate was 36.4% (12/33) in the embedding group, which was superior to 3.0% (1/33) in the Kuntai group (P<0.05); however, after 30 days and 60 days of treatment, the differences of each index between two groups were not statistically significant (all P>0.05).

CONCLUSIONBoth the acupoint catgut embedding and Kuntai capsule could reduce the score of KI and improve clinical symptoms, and the acupoint catgut embedding has certain advantage on the early stage of treatment.

OBJECTIVETo observe the effect of Buyang Huanwu Decoction (BYHWD), a representative formula of qi benefiting blood activating method on aorta Rho associated coiled-coil forming protein serine/threonine kinase (Rhokinase, ROCK) and nuclear transcription factor kappa B (NF-κB) p65 mRNA expressions and levels of blood lipids in atherosclerosis (AS) model rats.

METHODSThe AS rat model was prepared by vitamin D3 and high fat diet. Totally 60 rats were randomly divided into 6 groups, i.e., the normal control group, the model group, the low dose BYHWD group (10 g/kg), the high dose BYHWD group (20 g/kg), the Simvastatin control group (0.6 mg/kg), and the BYHWD prevention group (10 g/kg), 10 in each group. After successful modeling all medication was intervened for 28 days. Expression levels oxidized low density lipoprotein (ox-LDL) were detected by ELISA. Levels of TG, TC, LDL-C, HDL-C were determined by enzyme method. Pathological changes of aortic tissue were observed under light microscope. mRNA expressions of Rho kinase and NF-κB p65 in aorta were detected by real time (RT) PCR.

RESULTSHigh fat diet and peritoneal injection of vitamin D3 could induce AS rat model. Typical atheromatous plaque formed in aorta of AS model rats. Compared with the normal control group, levels of TC, TG, LDL-C, and ox-LDL significantly increased in the model group, but the HDL-C level decreased (P < 0.01). Compared with the model group, levels of TC, TG, LDL-C, and ox-LDL all decreased, but HDL-C increased in low and high dose BYHWD groups, the Simvastatin control group, and the BYHWD prevention group (P < 0.05, P < 0.01). Compared with the low dose BYHWD group, above-mentioned indices were more obviously lowered in the high dose BYHWD group, the Simvastatin control group, and the BYHWD prevention group (P < 0.05). Compared with the normal control group, mRNA expression levels of Rho kinase and NF-κB p65 significantly increased in the model group (P < 0.01). Compared with the model group, mRNA expressions of Rho kinase and NF-κB p65 obviously decreased in low and high dose BYHWD groups, the Simvastatin control group, and the BYHWD prevention group (P < 0.01). Compared with the low dose BYHWD group, the two indicators were more obviously lowered in the high dose BYHWD group, the Simvastatin control group, and the BYHWD prevention group (P < 0.05). But there was no statistical difference in blood lipids levels, mRNA expression levels of Rho kinase or NF-κB p65 among the high dose BYHWD group, the Simvastatin control group, and the BYHWD prevention group (P >0. 05).

CONCLUSIONSBYHWD could down-regulate mRNA expression levels of Rho kinase and NF-κB p65, lower levels of blood lipids, and fight against AS. Suppressing Rho kinase pathway might be one of its mechanisms.
