Objective: To examine the characteristics of childhood traumatic experiences in borderline personality disorder (BPD) in college students. Methods: The Personality Diagnosis Questionnaire-~(4+) (PDQ-~(4+)), Personality Disorder Interview- Ⅳ (PDI - Ⅳ) and Childhood Trauma Questionnaire -28 Short Form (CTQ-SF) were administered to 3227 college students of sophomore and junior. Results: (1) In the investigation of PDQ-~(4+), 31 subjects with childhood traumatic experiences (0.96%) were diagnosed as BPD, and the total score of BDL sub-scale was (2. 62 ± 1.70), including 18 females and 13 males. In CTQ test, the scores of bad environment in females were significantly higher than that in males [(13.63±4.54) vs. (9.83±1.95), P<0.01] . (2) Subjects with BPD got higher scores than normal controls in CTQ-SF, such as the emotional abuse [(2.11 ±0.77) vs. (1.66±0.49), P<0.01] .Conclusion: college students with borderline personality disorder mostly have d different childhood traumatic experiences, and there exists a sex difference.

The tumor volumes of mice for 21 d in the NC+ empty vector group, miR-20a-5p+ empty vector group and miR-20a-5p+ KDM6B group were (1 667.50±250.40) mm 3, (129.20±21.00) mm 3 and (775.41±77.51) mm 3 respectively, with a statistically significant difference ( F=77.651, P<0.001). The tumor weights of the 3 groups were (1.35±0.18) g, (0.12±0.01) g and (0.61±0.03) g respectively, with a statistically significant difference ( F=104.191, P<0.001). Conclusion:The expression of miR-20a-5p is significantly decreased in osteosarcoma tissues, and the expression of KDM6B is significantly increased in osteosarcoma tissues. Overexpression of miR-20a-5p may inhibit the proliferation, migration and invasion of osteosarcoma cells and tumor growth by targeting to reduce the expression of KDM6B.

Trachoma, a contagious keratoconjunctivitis ( KC ) , caused by Chlamydia trachomatis infection, is rife in 57 countries in the world at present. The World Health Organization ( WHO) listed the global alliance to eliminate blinding trachoma by 2020 as one of top priorities of its blindness prevention in 1998. A simplified classification system for identifying and naming trachoma, designated by WHO, and the SAFE strategy based on community intervention were extended continuously in the world in 10 years since then. The trachoma prevalence trend has showed a change compared with that in the past. China has launched the blindness prevention action, aimed to eliminate blinding trachoma by 2016. In this paper, we reviews progress in diagnosis, treatment and epidemic of trachoma since the extension of the SAFE strategy.

Objective To study the effect of selenium on peripheral and splentic T-cell subset, apoptosis of spleen cells in fluorosis chicken and its mechanism. Methods One hundred and eighty 8-day Hailanhe chicks were randomly divided into 3 groups(each 60): ①control group: 195 mg/kg fluoride and 0.08 mg/kg of selenium; ②fluorine group : 1000 mg/kg fluoride and 0.08 mg/kg of selenium ;③selenium antagonism group : 1000 mg/kg On 30~(th), 60~(th), 90~(th) day, peripheral and splentic CD4~+, CD8~+ T-cell subset analyses underwent flow cytometry and apoptosis of spleen cells were detected by TUNEL for study subjects.

OBJECTIVETo study the effect of Chinese drugs for invigorating qi and tonifying Shen (IQTS) on expression of CD4+CD25+ regulatory T cells in spleen and maternal-fetal interface of abortion-prone mice during pregnancy.

METHODSCBA female mice were mated with DBA/2 male mice to establish abortion-prone models, which were randomly divided into 4 groups, the negative control group (fed with normal saline), the positive control group (treated with CsA), the Chinese medicine group (treated with IQTS), and the Chinese and Western medicine group (treated with IQTS+CsA). Mice were sacrificed in batches on the 9th and the 14th day of gestation, their splenic and decidual tissues were taken out to analyse CD4+CD25+ regulatory T-cell expression by flow cytometry.

RESULTSCompared with the negative control group, the expression of splenic CD4+CD25+ regulatory T all significantly increased on the 9th day of gestation (P < 0.01 or P < 0.05). There was no statistical difference in intergroup comparison of the three treatment groups (P > 0.05). Compared with the negative control group, the expression of splenic CD4+CD25+ regulatory T all significantly increased on the 14th day of gestation (P < 0.01 or P < 0.05). Of them, its expression was the highest in the Chinese and Western medicine group, showing significant difference from that in the Chinese medicine group and the positive group (P < 0.01). The difference between the Chinese medicine group and the positive group was insignificant (P > 0.05). On day 9 of gestation, compared with the negative control group, the expressions of CD4+CD25+ regulatory T in maternal-fetal interface increased in the three treated groups, showing no statistical significance (P > 0.05). Its expression was ordered from high to low in sequence as the Chinese and Western medicine group, the positive control group, the Chinese medicine group, and the negative control group. On day 14 its expression was obviously enhanced in the Chinese and Western medicine group, showing statistical difference from that in the negative control group (P < 0.05). But its expression was obviously enhanced in the Chinese medicine group and the positive group, showing insignificant difference from that in the negative group. The same sequence was found in the percentage of CD4+CD25+ T cells in CD4+ T cells.

CONCLUSIONSChinese drugs for IQTS could up-regulate the expression of CD4+CD25+ regulatory T in spleen of abortion-prone mice in the early and late pregnancy stages. When combined with CsA, it also could up-regulate its expression in maternal-fetal interface in the mid and late pregnancy stages, suggesting that Chinese drugs for IQTS are facilitate to maintain the immune tolerance state in mice during pregnancy.

This paper aims to construct a Bayesian(BN) fault diagnosis model of traditional Chinese medicine dry granulation based on the failure model and effect analysis(FMEA), effectively control risk factors and ensure the quality of granules.Firstly, the risk ana-lysis of dry granulation process was carried out with FMEA, and the selected medium and high risk factors were taken as node variables to establish corresponding BN network with causality.According to the mathematical reasoning method of probability theory, the model was accurately inferred and verified by Netica, and the granule nonconformance was used as the evidence for reversed reasoning to determine the most likely cause of the failure that affected the granule quality.The BN fault diagnosis model of traditional Chinese medicine dry gra-nulation was established based on the medium and high risk factors of process, prescription and equipment screened out by FMEA, such as roller pressure, raw material viscosity, clearance between rollers in the paper.The fault diagnosis of traditional Chinese medicine dry granulation process was then carried out according to the model, and the posterior probability of each node under the premise of nonconforming granule quality was obtained.This method could provide strong support for operators to quickly eliminate faults and make decisions, so as to improve the efficiency and accuracy for fault diagnosis and prediction, with innovation in its application.
