This study was aimed to solve the problem of overall syndrome differentiation information collection on patient’s main complain of traditional Chinese medicine (TCM) four diagnostic methods, in order to make syndrome differentiation standard of premenstrual syndrome (PMS) with liver-qi invasion pattern. The method of cluster sampling was applied in the investigation. The appropriate structural equation modeling (SEM) was established according to multi-dimension indexes of case features and TCM theories. The results of the “information acquisition form for doctor” structural equation showed that emotion dimension, body-symptom dimension, organism condition dimension load coefficients were 0.715, 0.574 and 0.904, respectively. The results of the “information acquisition form for patient” structural equation showed that emotion dimension, body-symptom dimension, organism condition dimension load coefficients were 0.705, 0.945 and 0.848, respectively. There were strong relativities among all dimensions. Combined with TCM theories, the main symptom of identified PMS with liver-qi invasion pattern was “irritable and angry”. And the secondary symptoms contained headache, breast tenderness, distention and pain of lower abdomen and stomach. The combining symptoms were insomnia, dreaminess, swelling of extremities, fatigue, inefficiency for work and housework, hard to focus the attention. It was concluded that the combination of information acquisition method from both the doctor and patient established a relative comprehensive information acquisition system. It established the syndrome differentiation standard of PMS with liver-qi invasion pattern for the first time based on epidemiologic investigation. It provided important reference for the study of PMS subtype.

Objective To investigate the role of synaptic plasticity on the formation of visceral hypersensitivity induced by transient intestinal infection in rats. Methods Thirty male Sprague-Dawley rats were divided into normal control, acute infection and chronic infection groups with 10 each. The area under curve (AUC) of electromyography (EMG) in 10 s was used to evaluate the visceral sensitivity induced by different eolorectal distention (20,40,60 and 80 mmHg). Histological change of the colon was evaluated by H-E staining. Synaptic uhrastrueture such as synaptic cleft and synaptic vesicles was observed using transmission electron mieroseope. The mRNA and protein expressions of synaptophysin and postsynaptic density protein-95 (PSD-95) were examined by RT-PCR and Western blot, respectively. significantly higher than those of normal controls(P=0. 012, 0. 005, respectively ). In contrast, AUC of acute infection were significantly lower than those of normal controls ( P = 0. 018,0. 012, respectively ). Under the distention of 20 and 80 mmHg, no significant difference was observed among three groups (P= rats compared to normal controls(23.45±4.10 vs. 9.10±2.42, P=0. 027),but there was no statistical difference between chronic infection rats and normal controls (13. 95±7.96 vs. 9.15±2.42, P=0.78). increased. In acute infection rats, mitochondria cristae disappeared, synaptic vesicles and the length of controls, mRNA and protein of synaptophysin in ileocecum, proximal colon and distal colon were significantly increased in chronic infection rats (P<0. 05 ), but decreased in acute infection rats with no significant difference. Compared with controls, no significant downregulation was noted in the expression protein expressions of PSD-95 were both increased in chronic infection rats (P<0.05), and decreased in acute infection rats (P<0.05). Conclusion Synaptic plasticity plays an important role in the formation of visceral hypersensitivity induced by transient intestinal infection in rats.

The endocytosis/phagocytosis of calcium alginate nanocapsules by peripheral blood derived dendritic cells was confirmed with the use of Quantum dots labeling.Results further demonstrated these nanoparticles could cause the upregulation of HLA-DR expression to induce the maturation of dendritic cells in vitro.Dendritic cells stimulated by nanocapsules covalently loaded with BSA were shown to stimulate the proliferation of self T cells with blank capsules and free BSA as controls,suggesting their potential applications in cancer cell therapy as a new antigen delivery vehicle with a strong adjuvant effect.

This study is to establish the methods for determination of iridoid glycosides and triterpenic acids in Corni Fructus and provide technical support for the quality control of Corni Fructus. Morroniside, loganin and sweroside were determined by HPLC-UV method with acetonitrile and 0.1% formic acid as the mobile phase, and the detective wavelength was set at 240 nm. Oleanolic acid and ursolic acid were determined by HPLC-ELSD method with methanol-0.5% ammonium acetate (87:13) as the mobile phase. The results showed that the linear ranges of morroniside, loganin and sweroside were 5.335-213.4 mg · L(-1) (r = 0.9999), 5.515-220.6 mg · L(-1) (r = 1.0000), 1.992-79.68 mg · L(-1) (r = 1.0000), respectively. The average recoveries of the above three iridoid glycosides were 98.49%-99.28% with RSDs of recoveries being less than 2%. The linear ranges of oleanolic acid and ursolic acid were 7.74-154.8 mg · L(-1) (r = 0.9964), 10.82-216.4 mg · L(-1) (r = 0.9996), respectively. The average recoveries of the above two triterpenic acids were 98.11%-99.27% with RSDs of recoveries being less than 3%. The method established in this research is simple, rapid and reliable, and can be used for quality control of Corni Fructus. Furthermore, the research provided experimental data for the improvement of present quality standard of Corni Fructus, which has important significance to guarantee its quality and clinical curative effect.

Objective To explore the lowest effective dosage of mifepristone combined with misoprostol in terminating ultra-early pregnancy.Methods All the cases of ultra-early pregnancy classified by amenorrhea days,β-hCG and vaginal B-ultrasonic were randomly divided into two groups.One hundred cases in G1 group (minimized dosage) were orally administered 25 mg mifepristone once a day for 2 days and combined with 200 μg misoprostol 48 hours later,while 150 mg mifepristone combined with 600 μg misoprostol 48 hours later were given to 100 cases in G2 group (normal dosage).All cases were observed for 6 hours after taking misoprostol and returned for assessment three days later.Results None missing.Expulsion of conceptus:G1 and G2 group were 22 (22.0%,22/100) and 25 (25.0%,25/100;P > 0.05).Failure rate:cases with incomplete abortion were 1 (1.0%,1/100) and 2 (2.0%,2/100) in G1 and G2 group,hospitalization for suspected ectopic pregnancies both was 1 (1.0%).Bleeding:bleeding cases during the administration of mifepristone in G1 and G2 group were 71 (71.0%,71/100) and 78 (78.0%,78/100; P>0.05); the mcan bleeding time were (5.3 ± 1.4) days and (6.0± 1.5) days (P <0.01).Other side effects:in G1 group,majority showed light nausea (7.0%,7/100) and light abdominal pain (20.0%,20/100).Menses recovery:99 (99.0%,99/100) for G1 group and 98 (98.0%,98/100) for G2 group to recovery on scheduled time.Satisfactions:both were 99 (99.0%,99/100).Except mean bleeding days and side-effects,the differences above showed no significance (P > 0.05).Conclusion It is safe and effective treatment with the lowest dosages of mifepristone and misoprostol to terminate ultra-early pregnancies.

Objective To compare the consistency of immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) in detecting c-erbB-2 status in breast cancer tissues. Methods A total of 50 breast cancer paraffin embedded samples were selected, of which there were 10 cases of c-erbB-2 protein expression (+), 20 cases of (++) and 20 cases of (+++). FISH was used to assess the amplification of c-erbB-2 gene, and SPSS 13.0 software was employed to analyze the difference and consistency between the two methods. Results IHC and FISH methods had a good consistency when detecting c-erbB-2 (+) and (+++) expressions in breast cancer tissues, with the coincidence rate of 89.2%. However, when IHC was used to test c-erbB-2 (++), the result of FISH was quite different, with the coincidence rate of only 35.3%. Conclusion IHC is a preliminary method to detect c-erbB-2 status in breast cancer. IHC and FISH methods have a good consistency in detecting c-erbB-2 (+) and (+++) status in breast cancer tissues. As detection of c-erbB-2 (++) with IHC has a different result from FISH, such patients should receive FISH confirmation for herceptin therapy.
