Objective To analyse the maternal and perinatal morbidity after 40 weeks and postdate pregnancy,and to research suitable time of labor induction. Methods Clinical data of 357 pregnant women after 40 weeks with normal menstrual period were analysed.They were divided into four groups according to the different weeks of gestation. Results There were no significant difference in the four groups for maternal and perinatal morbidity,the rate of spontaneons labor,the degree of cervical repine and the successful rate of labor induction.The successful rate of artificial rupture of membranes was higher in the groups with Bishop score ≥6(P

Objective To explore the effect of nuclear factor-kappaB(NF-?B) on cardiac myocyte apoptosis and understand the molecular mechanism of decrease of heart function in septic shock rats.Methods Twenty Wistar rats were randomly divided into the septic shock group and the normal control group.The septic shock group(n=10) were fixed with anaesthesia and made into 1.5 cm slices just along the abdomen midline.Then the roots of appendices were returned to the belly cavity after being ligated and punctured 4 times with the No.14 pinhead.After that,the slices were sewn up layer by layer.After 12 hours,the rats were all sacrificed,the blood taken and the serum separated.In the end,the heart specimens of the septic shock group were set aside.Meanwhile,the normal control group were dealt with in the same way except that they were not subjected to cecal ligation and puncture.Then NF-?B protein levels in cardiac tissue and the index of cardiac myocyte apoptosis were measured.Results NF-?B protein levels in the septic shock group(9 cases were strong masculine gender,1 case was middle masculine gender)elevated significantly compared with the normal control group(8 cases were negative gender,2 cases were weak masculine gender) in cardiac tissue(P

To explore the correlation between the ecological factors and the contents of podophyllotoxin and total lignans in root and rhizome of Sinopodophyllum hexandrum, podophyllotoxin in 87 samples (from 5 provinces) was determined by HPLC and total lignans by UV. A correlation and regression analysis was made by software SPSS 16.0 in combination with ecological factors (terrain, soil and climate). The content determination results showed a great difference between podophyllotoxin and total lignans, attaining 1.001%-6.230% and 5.350%-16.34%, respective. The correlation and regression analysis by SPSS showed a positive linear correlation between their contents, strong positive correlation between their contents, latitude and annual average rainfall within the sampling area, weak negative correlation with pH value and organic material in soil, weaker and stronger positive correlations with soil potassium, weak negative correlation with slope and annual average temperature and weaker positive correlation between the podophyllotoxin content and soil potassium.

RNA-Sequencing (RNA-Seq) is a newly-developed method in transcriptome research, it can afford more accurate transcription information and be more quickly by using Next-generation Sequencing (NGS) technology. RNA-Seq has been widely used in various biological fields. Genuine traditional Chinese medicines (TCM), with good quality and therapeutic effect, were always praised highly and used by famous physicians. The geo-herbalism formation of TCM is based on the product of the gene expression at specific space and time. So it has been a research hotspot to analyze the mechanism of biosynthesis through RNA-Seq in the study on the secondary metabolism of medicinal plant. This article mainly illustrates the RNA-Seq and its advantages, it also discusses the potential application in genuine TCM, and it can provide useful information for other researchers.

The purpose of this study is to explore the feasibility of wheat germ agglutinin (WGA) modified liposome as a vehicle for ophthalmic administration. Liposome loaded with 5-carboxyfluorescein (FAM) was prepared by lipid film hydration method. WGA was thiolated and then conjugated to the surface of the liposome via polyethylene glycol linker to constitute the WGA-modified and FAM-loaded liposome (WGA-LS/FAM). The amount of thiol groups on each WGA molecule was determined, and the bioactivity of WGA was estimated after it was modified to the surface of liposome. The physical and chemical features of the WGA-modified liposome were characterized and the ocular bioadhesive performance was evaluated in rats. The result showed that each thiolated WGA molecule was conjugated with 1.32 thiol groups. WGA-LS/FAM had a mean size of (97.40 +/- 1.39) nm, with a polydispersity index of 0.23 +/- 0.01. The entrapment efficacy of FAM was about (2.95 +/- 0.21)%, and only 4% of FAM leaked out of the liposome in 24 h. Erythrocyte agglutination test indicated that after modification WGA preserved the binding activity to glycoprotein. The in vivo ocular elimination of WGA-LS/FAM fitted first-order kinetics, and the elimination rate was significantly slower than that of the unmodified liposome, demonstrating WGA-modified liposome is bioadhesive and suitable for ophthalmic administration.

OBJECTIVETo observe the curative effect of Qingjin Runfei Decoction (QRD) combined with hormone and antibiotic in treating radiation pneumonia (RP).

METHODSPatients were randomly assigned to two groups, the control group (51 cases) treated with hormone and antibiotic and the treated group (53 cases) with the above therapy plus QRD. The curative effects on RP, quality of life (QOL), chest radiography and TCM symptoms were observed.

RESULTSThe curative effects on the above items in the treated group were all significantly better than those in the control group (P < 0.05).

CONCLUSIONQRD could enhance the effects of hormone and antibiotic in treating RP, as well as improve QOL of the patients.

OBJECTIVE: To study the mTOR expression of cancer stem cells(CSCs) in nasopharyngeal carcinoma and preliminarily explore the mechanism of inhibiting its proliferation with rapamycin. METHOD: Nasopharyngeal carcinoma spherical cells were gathered by using serum-free suspension culture method, CCK8 assay was used to detect cell proliferation, Western blot assay was used to detect the expression of CD44, OCT4, SOX2 and mTOR signaling. The spherical cells and CNE2 were treated with rapamycin in concentrations of 0, 0.1, 1.0, 10.0, 100.0, 1000.0 nmol/L, CCK8 assay was used to detect cell inhibition ratio, Western blot assay was used to detect the expression of mTOR signaling of nasopharyngeal carcinoma spherical cells. RESULT: Compared with CNE2, the spherical cells exhibited a high proliferation rate in RPMI 1640 medium supplemented with fetal bovine serum, and overexpressed in OCT4, SOX2 (P < 0.05), but not that of CD44 (P > 0.05). Although the expression levels of mTOR, P70S6, 4EBP1 were not significantly different between the two kinds of cells (P > 0.05) the proteins of phosphorylation activation form of them (P-mTOR, P-P70S6, P-4EBP1) were highly expressed in spherical cells (P < 0.05). The spherical cells and CNE2 were treated with rapamycin in different concentrations, the concentrations for 50% of maximal effect of spherical cells and CNE2 were 2.59 nmol/L and 78.12 nmol/L respectively, rapamycin inhibited the spherical cells more strongly compared with CNEZ. The expression levels of P-mTOR, P-70S6, P-4EBP1 in spherical cells were gradually decreased with increasing of the concentrations of rapamycin, but the difference of the expression levels of mTOR, P70S6, 4EBP1 were not significant. CONCLUSION The proteins of mTOR signaling pathway of CSCs in nasopharyngeal carcinoma are overexpressed, and rapamycin can effectively inhibit cell proliferation of CSCs in nasopharyngeal carcinoma by blocking mTOR signaling pathway.

Objective To investigate the pregnancy outcomes of couples with either maternal or paternal balanced translocations.Methods One hundred and ninety-four couples were divided into three groups based on the kind of translocations:135 with reciprocal translocation,52 with nonhomologous Robertsonian translocations,and 7 with homologous Robertsonian translocations.Past reproductive histories were surveyed.For those who wanted to have their own babies by natural conceptions after knowing their karyotypes as well as the risks of abnormal offsprings,subsequent pregnancy outcomes were recorded.Total pregnancy outcomes were compared between three groups.Results(1)503 previous and subsequent pregnancies were recorded in detail.The pregnancy outcomes are as follows:spontaneous abortions 81.7% (411/503);induced terminations because of fetal abnormalities 3.2%(16/503);birth defects 7.2% (36/503);normal/balanced offsprings 8.0%(40/503).In reciprocal translocations,nonhomologous Robertsonian translocations and homologous Robertsonian translocations,the birth defects rates were 5.7% (20/350),10.9%(14/128)and 8.0%(2/25),respectively(P
