Objective To screen out some Chinese medicines with obvious inhibitory actions on triple-negative breast cancer based on data mining. Methods Literatures of breast cancer effectively treated by Chinese medicine issued in recent 15 years were collected, and then the frequency analysis and cluster analysis were used to screen the frequently-used herbs. According to the above results, the serum containing the obtained drugs were prepared respectively. And then the proliferation, migration and invasion abilities of breast cancer cells MDB-MB-231 treated with the serum containing various Chinese medicines for 12, 24 h were observed by methyl thiazolyl tetrazolium(MTT) assay and transwell cell invasion and migration experiments, respectively. Results The frequently-used herbs were screened out as Rhizoma Chuanxiong, Herba Taraxaci, Herba Hedyotis Diffusae, Radix Trichosanthis, Radix Achyranthis Bidentatae. The proliferation of MDB-MB-231 cells was significantly inhibited by serum seperately containing Rhizoma Chuanxiong, Herba Taraxaci, Herba Hedyotis Diffusae, Radix Trichosanthis, and Radix Achyranthis Bidentatae to different degrees, and the migration abilities of MDB-MB-231 cells were obviously inhibited by serum containing Herba Taraxaci, Herba Hedyotis Diffusae, Radix Achyranthis Bidentatae, respectively. And the invasion abilities of MDB-MB-231 cells were obviously inhibited by serum containing Herba Taraxaci, Rhizoma Chuanxiong, Herba Hedyotis Diffusae, respectively. Conclusion Chinese medicines such as Rhizoma Chuanxiong, Herba Taraxaci, Herba Hedyotis Diffusae, Radix richosanthis, Radix Achyranthis Bidentatae obtained by data mining technology have obviously inhibitory effects on triple-negative breast cancer.

Objective To study the effect of the long-term administration of hemocoagulasein vitro and in vivo,whether it may cause hypofibrinogenemia and changes of cytokine interleukin-6(IL-6) expression level which related to fibrinogen synthesis.Methods Totally 50 healthy subjects pooled plasma was chose in vitro experiments,which was divided into 7 groups.After that,added various of dilutions of injection hemocoagulase and incubated at 37 ℃,detected FIB concentration every 12 h.In vivo experiments,80 rats with six-week old were randomly divided into 4 groups:negative control group,high-dose group,middle-dose group,low-dose group,After 3 weeks administration,the serum level of Ⅴfactor,Ⅷ factor,PT,activated partial thromboplastin time (APTT),FIB,IL-6 was detected.Results Hemocoagulase in vitro had a strong role to reduce fibrin,and showed a significant dose-dependent and time-dependent;Hemocoagulase prolonged low-dose use might reduce the concentration of FIB in mice,but theⅤfactor,Ⅷ factor,PT,APTT,TT were not significantly affected.Compared with the negative control group,FIB and IL-6 concentration decreased in high-dose group,middle-dose group,low-dose group and had statistically significant differences (P<0.05);The level of FIB among the groups had statistically significant differences (P<0.05).The APTT of the middle and high dose groups was slightly prolonged,which was significantly different from that of the negative control group (P<0.05).Conclusion Hemocoagulase has a strong effect to reduce the concentration of fibrin,when there is a long-term medication,fibrin concentration of the patient should be closely monitored,hemocoagulase not only directly decomposed fibrin,but also may affect the synthesis of IL-6,the specific mechanism needs further study.

Objective To observe the impact of the five-emotion restrictive therapy on coronary heart disease. Methods109 hospitalized patients with coronary heart disease were randomly divided into a experimental of 56 patients and a control group of 53 patients according to length of stay. The control group was treated with the conventional therapy; the experimental group was imposed five-emotion restrictive psychological intervention on the basis of conventional therapy. The investigation was done using self-rating anxiety scale(SAS) and self-rating depression scale(SDS) on 1 day after admission and ld before discharge respectively. SAS and SDS scores were surveyed. At the same time Holter monitoring and normal ECG test were compared. Results Compared with control group, the experimental group 1 d before discharge of the SAS and SDS scores were (41.9±7.4) and (38.6±8.4), and the difference was statistically significant (P＜0.01) . The total effective rate of Holter monitoring and normal ECG was 64.15％ and 92.85％ in the control and experimental group, and the difference was significant (P＜0.01) . ConclusionThe pathological seven emotions have a certain affection on the incidence of coronary heart disease, treatment and prognosis of the course. Five-emotion restrictive psychological intervention can adjust timely psychological state of patients, eliminate negative emotions, and significantly help the incidence, treatment and prognosis of the disease.

Phagocytic capacities of both dendritic cells (DC) and macrophages(M?) in the DC-enriched fractions isolated from rat spleen were comparatively observed under electron microscope. Experiments were divided into two groups: in vitro and in vivo. In group 1, candida albicans(CA), cock red blood cells (CRBC) and CRBC opsonized with rat antiserum against CRBC (OCRBC) used as phagocytic markers were incubated with the DC-enriched fractions for 1h at 37℃ separately in vitro. In group 2, colloidal carbon (CC) (india ink) and heat killed Candida albicans (HKCA) were injected in vivo. The animals were sacrificed 18h later and DC-enriched fractions were isolated from the spleens. The results are as follow: generally, in the cytoplasm of DC, no phagocytic markers were identified except a few of DC ingested a small amount of CC in vivo and few CA occationally in vitro, while M? under the same conditions, ingested a lot of the substances mentioned above. It indicates that spleen M? phagocytose actively either to immunogenic or non-immunogenic, opsonized or non-opsonized particles (especially to opsonized particles), while DC in the same preparations are not.

Expression of Ia-antigen on cells in lymphoid dendritic cells (LDCs)-enrt- ched fractions isolated from unstimulated rat spleens was observed with ABC immunoperoxidase and indirect immunofluorescent staining methods. The results appeared that there were three types of cells in stained preparaions: 1. Large cells with dendritic processes on their surfaces showed dark brown in colour with ABC staining method and emitted intense light-green fluorescence with immuno- fluorescent staining technic. 2. Large rounded or ovoid cells without obviously ramifications revealed colourless or light yellow-brown in colour with ABC sta- ining method and emitted no or weak yellow-green fluorescence with immuno- fluorescent staining technic. 3. Spherical lymphocytes of varying in size were similar to type 2 cells in immunoreactivity. The results of SEM and S-100 pro- tein staining confirmed that these three types of cells were LDCs, macrophages and lymphocytes in turn. It is indicated that LDCs consistently expressed Ia- antigen in large amount on their surfaces.

Objective To evaluate the relationship between 25-(OH) vitamin D [25-(OH) D] level and peripheral neuropathy in patients with type 2 diabetes mellitus.Methods Eighty patients with type 2 diabetes mellitus were enrolled in this cross-sectional study,including 37 subjects with and 43 without diabetic neuropathy.Anthropometric data was collected and serum levels of 25-(OH) D,HbA1c,blood lipid,and hepatic and renal functions were determined in all patients.Results Serum 25-(OH) D level was significantly lower in patients with diabetic neuropathy compared to those without neuropathy [(12.73 ± 4.68 vs 17.56 ± 5.28) ng/ml,P＜0.01].Logistic regressions demonstrated that vitamin D level was associated with diabetic neuropathy (OR=1.222,95％ CI 1.095-1.364).Conclusions Vitamin D insufficiency is associated with diabetic peripheral neuropathy.25-(OH) D level seems to be an independent risk factor of diabetic neuropathy in patients with type 2 diabetes mellitus.
