Objective:To methodologically establish the lentivirus granule packaging, concentration and infection against CD34~+ cells from umbilical blood. Methods:The lentivirus system of the 3~(rd) generation was used to produce the virus. Ultrafiltration and ultracentrifugation were employed to concentrate virus. Several treatments were used to improve virus infection including in vitro amplification culture, facilitation of rest cells into cell cycle, promotion of cell adhesion and immobilization during infection, and repeat infection methods. Results:CD34~+ cells were not obviously changed by checking the expression level of CD34 marker on the cell surface after 48 h culture. After two-step concentration, virus titer was increased up to 5.06×10~7/ml, and the infection rate against CD34~+ cells from umbilical blood was increased up to 37.7%.Conclusion:Lentivirus supernatant with over 10~7/ml titer can be obtained using the above methods. Efficient infection against CD34~+ cells from umbilical blood can be achieved.

Objective To explore the implementation situation and influencing factors of long-acting reversible contraception (LARC) after receiving post-abortion care (PAC) in artificial abortion women.Methods According to the demographic characteristics and abortion risks,4 068 artificial abortion women in the family planning clinic of our hospital were classified.The LARC implementation situation after receiving PAC was compared among different characteristic populations.The Chi square test was utilized to analyze the statistical significance of the data by SAS software.Results The LARC rate in young women was 7.9%),which was lower than 27.7% in 19-40 years old women and 11.8% in perimenopausal women;the LARC rate in nulliparous women was 10.6%,which was lower than 27.7% in parous women;the LARC rate in high-risk abortion women was 33.1%,which was higher than 16.6% in low-risk abortion women,these data analysis had statistically significant significance (P<0.05).The LARC rate in ≤ 20 years old women among high-risk abortion women,breastfeeding women,delivery women within three months,cesarean section women within six months and more than three times artificial abortion women was low (< 50%).However,the LARC rate in the scar pregnancy women and more than two times cesarean section women was high (> 80%).Conclusion Young women,nulliparous women and postpartum women in high-risk artificial abortion should be ranked the focus group for PAC consulting.

Endophytic fungi were isolated from Macleaya cordata growing in Dabie Mountain by agar-block method, and then the endophytic fungi were grouped into different types based on their morphological characteristics, and thin layer chromatography (TLC) and high performance liquid chromatography (HPLC) were employed to determine whether the metabolic substances contained sanguinarine or not, and then preliminarily identified by morphological method. The results showed that the leaves hosted the largest number of endophytes (96 isolates) followed by the stems (57 isolates) and finally the roots (28 isolates), respectively. Based on morphological characteristics the endophytic fungi were grouped into 26 types in our study. TLC and HPLC results showed that there was sanguinarine in the metabolic substances of BLH 51 strain. According to the morphological characteristic, the BLH 51 strain was identified as Fusarium proliferatum. All these indicated that the medicinal plant M. cordata harbors abundant endophytes, which could be a new source for the search of active secondary metabolites.
