Objective To analyze the effection of improved three-dimensional conformal radiotherapy (3D-CRT) to the dose of target area of local advanced non-small-cell lung cancer (NSCLC) and observe the therapeutic efficacy and toxity.Methods 81 patients with local advanced NSCLC were collected and treated.The diameter of tumor exceed 5 cm.52 patients were squamous carcinoma.24 patients were adencarcinoma.5 patients were adenosquamous carcinoma.63 patients were onstage of Ⅲ A,18 patients were Ⅲ B.The patients were randomized into two groups,the first group was unmodified planning of 3D-CRT group (T1 group,39 patients),the second group was modified planning of 3D-CRT group (T2 group,42 patients).The 31 patients of T1 group (79.5 %) received radiotherapy and chemotherapy.Toties quoties was 2 Gy.The fractions were 26-30.The total dose was 52-60 Gy.The 31 patients of T1 group (73.8 %) received radiotherapy and chemotherapy.Toties quoties was 2 Gy.The fractions were 30-35.The total dose was 60-70 Gy.Results The 1-,2-,3-year overall survive rates of T1 group were 56.4 %,33.3 %,28.4 %,the 1-,2-,3-year local control survive rates were 38.4 %,28.2 %,20.5 %,and the median survive time was 17 months.The 1-,2-,3-year overall survive rates of T2 group were 61.9 %,35.7 %,28.5 %,the 1-,2-,3-year local control survive rates were 47.6 %,40.4 %,30.9 %,and the median survive time was 19 months.The significant difference was found for the local control survive rates between T1 and T2 group (P < 0.05).No significant difference was found for the overall survive rates and the median survive time between T1 and T2 group (P > 0.05).Conclution Improved 3D-CRT can advance local control survive rate and living quality to local advanced NSCLC.Meanwhile,it also increases survive rate of 1-year,but can not increase long-time survival rate.

Double cannulation model of conscious rat allowing simultaneous collection of mesenteric lymph and jugular venous blood was established to investigate the intestinal lymphatic transport of breviscapine orally administered in rat. The concentrations of breviscapine in plasma and lymph were determined by HPLC. The pharmacokinetics of breviscapine after oral and intravenous administration was evaluated in the conscious rat model. It was observed that scutellarin distributed from blood circulation to lymphatic system after intravenous injection. The cumulative lymphatic transport amount within 12 h was (2.78 +/- 0.25) microg, equivalent to 0.0792% of intravenous dose. After oral administration of scutellarin to double-cannulation rats, the cumulative lymphatic transport amount within 12 h was (0.92 +/- 0.08) microg, equal to 0.0083% of oral dose. The absolute bioavailability of breviscapine orally administered to double-cannulation rats was 4.91%, indicating that scutellarin was mainly absorbed into the bloodstream through the portal vein. Lymphatic transport of scutellarin appears to reflect high affinity for the lymph lipoproteins to chylomicron. This study provided a biopharmaceutics basis for developing oral lipid delivery system for the promotion of intestinal lymphatic transport to improve oral bioavailability of breviscapine.

Objective To survey birth defects of neonates conceived by using various types of in vitro fertilization and embryo transfer (IVF-ET) between 1998 and 2007 in Shanghai. Methods From 1998 to 2007, 8507 neonates from 6551 pregnancies conceived through assistant reproductive technology (ART) from 7 reproductive medicine center in Shanghai were enrolled in this retrospective study, including Shanghai Ji-Ai Genetics and IVF Institute, Shanghai Jiaotong University School of Medicine affiliated Renji Hospital,Buijin Hospital, China Welfare Institute International Maternal and Infant Health Hospital, Shanghai First Maternity and Infant Health Hospital, Shanghai the Ninth People's Hospital and the Second Military Medical University affiliated Changhal Hospital. The clinical data about the type and incidence of birth defect were analyzed. Meanwhile, the factors associated with birth defect were investigated, such as various ART,gender, mother age, numbers of gestational sac, the source and quality of sperm. Results The birth defect rate was 1.08% (92/8507) and the most remarkable malformation occurred in circulation system [34% (31/92)]. The rates of major congenital malformations were 1.21% (34/2799) in fresh conventional IVF-ET, 1.07% (20/1871) in IVF-frozen-thawed embryo transfer(IVF-FET), 1.04% (23/2212) in fresh intracyto plasmic sperm injection (ICSI)-ET and 0.92% (15/1625) in ICSI-FET, which did not show statistical difference (P>0.05). There was also no significantly different incidence of malformations between 1.12% (49/4371) in male neonates and 1.02% (42/4136) in female neonates (P >0.05).However, the occurrence of congenital malformation is positively related with maternal age, the rates were 0.84% (41/4884) in mother's age less than 30 years and 1.77% (16/902) in mother' age more than 35 years, which reached statistical difference (P < 0.05). It also showed remarkable different incidence among 0.53% (25/4679) in singletons, 1.59% (57/3576) in twins and 3.97% (10/252) in triplets (P< 0.05). No remarkable difference of malformation rate among sperm sources used in fertilization were observed, including 1.09% (81/7419)in ejaculated sperm, 1.21% (7/579)in percutaneous epididymal aspiration (PESA) and 0. 79% (4/509) in donor sperm (P>0.05). Conclusions The overall incidence of birth defect in neonates from ART is similar to those conceived naturally and is not associated with different types of IVF-ET, embryo cryopreservation, sperm sources. However, maternal age and multiple pregnancies coder the higher possibility of birth defect.
