BACKGROUND: Fetal microchimerism is a kind of stem cells which comes from fetus in pluripara. The research on fetal microchimerism is a hotspot because it may affect the health condition of pluripara.OBJECTIVE: To introduce the methods of how to detect fetal microchimerism, and the function of fetal microchimerism during disease and tissue repair of the mother.METHODS: Fetal microchimerism was used as a key word, and papers published before 2011-05-20 were retrieved in PubMed. Repetitive papers were eliminated.RESULTS AND CONCLUSION: Totally 655 papers were retrieved, and finally 26 were reviewed. There are several methods used for fetal microchimerism detecting, and fetal microchimerism may pay an important role in the pathomechanism of pluripara autoimmune diseases, cancer and tissue repair.

Methods:Poly-vinyl alcohol 124 (PVA124) and bletilla striata gum were selected as the film-forming materials. The amounts of PVA 124, bletilla striata gum, glycerol and absolute ethanol were used as the influencing factors in an orthogonal test with the composite score of film-forming time and appearance as the indices to screen out the best composition of film-forming materials. Results:The best composition of film-forming materials was as follows:8 g PVA 124, 1 g bletilla striata gum, 2 ml glycerol and 15 ml ethanol. Conclusion:The op-timized film-forming materials can be used for the preparation of compound rhizoma corydalis plastics.

Methods:The anti-dys-menorrhea effect of different extracts of Rupixiao granules was studied by writhing test induced by oxytocin in mice. Results:Compared with the model group, the extracts of Rupixiao granules could reduce the writhing times induced by oxytocin significantly (P<0. 05,P<0. 01 or P<0. 001), and the water-soluble extract showed the best effect (P<0. 001) without significant difference when compared with the positive control group(P>0. 05). Conclusion:The water-soluble parts of Rupixiao granules have significant anti-dysmenor-rhea effect.

The stratum corneum barrier and the other issues in transdermal drug delivery system have attracted more and more at-tention, and the novel liposomes as the drug delivery vehicles effectively solve the problems. The novel liposomes can significantly im-prove transdermal drug penetration, therefore, can enhance efficacy and shows high application value and development prospects. In the paper, combined with some domestic and foreign current researches, the classification, penetration mechanisms and application of the novel liposomes were reviewed.

Objective To develop a blood gas,acid-base imbalance analysis computer software to diagnose systematically,rapidly,accurately and automatically determine acid-base imbalance type,and evaluate the clinical application. Methods Using VBA programming language,a computer aided diagnostic software for the judgment of acid-base balance was developed. The clinical data of 220 patients admitted to the Second Affiliated Hospital of Guangzhou Medical University were retrospectively analyzed. The arterial blood gas〔pH value,HCO3-,arterial partial pressure of carbon dioxide(PaCO2)〕and electrolytes included data(Na+and Cl-)were collected. Data were entered into the software for acid-base imbalances judgment. At the same time the data generation was calculated manually by H-H compensation formula for determining the type of acid-base imbalance. The consistency of judgment results from software and manual calculation was evaluated,and the judgment time of two methods was compared. Results The clinical diagnosis of the types of acid-base imbalance for the 220 patients:65 cases were normal,90 cases with simple type,mixed type in 41 cases,and triplex type in 24 cases. The accuracy of the judgment results of the normal and triplex types from computer software compared with which were calculated manually was 100%,the accuracy of the simple type judgment was 98.9% and 78.0% for the mixed type,and the total accuracy was 95.5%. The Kappa value of judgment result from software and manual judgment was 0.935,P=0.000. It was demonstrated that the consistency was very good. The time for software to determine acid-base imbalances was significantly shorter than the manual judgment(seconds:18.14±3.80 vs. 43.79±23.86,t=7.466,P=0.000),so the method of software was much faster than the manual method. Conclusion Software judgment can replace manual judgment with the characteristics of rapid,accurate and convenient,can improve work efficiency and quality of clinical doctors and has great clinical application promotion value.

Objective:To determine the inhibitory effect of Rupixiao ( RPX) granule on mammary gland hyperplasia ( HMG) in rabbits and explore the possible mechanism to provide reference for clinical medication. Methods:Rabbit model of mammary hyperpla-sia was established by estradiol benzoate and progesterone. Xiaoyao pills and tamoxifen were used as the positive control, and the RPX granule group was respectively at low, medium and high dose (0. 525,1. 05,2. 1 g·kg-1). Each group was with intragastric adminis-tration for 30 days. The levels of E2 , PROG, FSH, LH and PRL in serum and the expression of VEGF in the homogenate tissue were determined by an Elisa method. The breast tissue of rabbits in each group was withdrawn to observe the structure changes after Hema-toxylin-eosin staining ( HE) . Results:Ovarian preservation-benzoic acid, estradiol combined with progesterone could be used to estab-lish mammary gland hyperplasia in rabbits. RPX granule could significantly decrease the serum levels of E2 and PRL (P<0. 01)and increase that of PROG (P<0. 01 or P<0. 001). The results of pathological section showed that the breast structure in RPX granule high dose group could be restored to the level of the blank control group, which showed its therapeutic effect on HMG was better than that of tamoxifen and Xiaoyao pills. The expression of VEGF in each treatment group significantly decreased compared with that in the model group by the Elisa reagent (P<0. 001). Conclusion:RPX granule has good efficacy in HMG rabbits. The inhibitory effects of RPX granule on HMG in rabbits maybe related to the inhibition of VEGF in rabbit breast tissues, and the inhibition of RPX granule was similar to that of tamoxifen and Xiaoyao pills.
