It is reported that anisodamine exhibited cell protection action during anoxia and ischemia, the mechanism of which is still obscure. Present study found that: (1) 654-2 significantly reduced the reperfusion mucosal damage of ischemic intestines and the accumulation of intracellular calcium; (2) anisodamine could blunt the contraction of the high potasium depolarized guinea pig ileum with calcium; (3) intermittent injections of 5mg/kg 654-2 significantly inhibited the cardiac function.The above results suggest that 654-2 possesses calcium-antagonist action, which may be one of the chief mechanism of its cell protection action.

This study investigated the reversal effect of isotetrandrine, an isoquinoline alkaloid extracted from Caulis mahoniae, on P-glyeoprotein-mediated multidrug resistance in human breast cancer doxorubicin-resistant (MCF-7/DOX) cells. RT-PCR assay and immunity histochemistry assay were used to determine the expression level of mdrl gene and P-gp in MCF-7/DOX cells to elucidate resistant character of MCF-7/DOX cells. The activity of isotetrandine to enhance doxorubicin cytotoxicity was tested using MTT (3-(4,5-dimethyhhiazol)-2,5-diphenyltetrazolium bromide) assay and was evaluated by the reversal fold (RF) values. Intracellular accumulation of doxorubicin was assessed by the determination of doxorubicin-assoeiated fluorescence intensity. Effect of isotetrandrine on the expression level of P-gp in MCF-7/DOX cells was then determined by immunity histochemistry assay. The ability of isotetrandrine to inhibit P-gp function was evaluated by detecting the accumulation and efflux of rhodamine123 ( Rh123 )with flow cytometry (FCM). Verapamil was employed as a comparative agent in whole experiment. The results indicated that MCF-7/DOX cells had phenotype of MDR and that the positive expression of P-gp MCF-7/DOX cells and reversal fold (RF) was significantly higher than that of verapamil (P < 0.05 ), butit hardly affected cytotoxicity of DOX in MCF-7 cells and the expression level of P-gp in MCF-7/DOXcells. The ability of isotetrandrine to inhibit P-gp function was reversible, because incubation of MCF-7/DOX cells with isotetrandrine caused a marked increase in uptake and a notable decrease in efflux of Rh123 and a marked increase of intracellular DOX concentrations. In conclusion, isotetrandrine exhibited potent effect on the reversal of P-gp-mediated MDR in vitro, suggesting that it might become a candidate of effective MDR reversing agent in cancer chemotherapy.

Objective To evaluate apelin level in patients with obesity and different glucose tolerances, investigate relevance of apelin with body mass index(BMI), blood lipid and blood glucose. Methods According to different glucose results of oral glucose tolerance test, 120 subjects were divided into three groups: normal glucose tolerance(NGT),impaired glucose tolerance(IGT) and type 2 diabetes(T2DM). All of the subjects were also divided into obese and non-obese subgroups based on their BMI(≥25kg/m~2 or ＜25kg/m~2 ). Plasma apelin levels were compared among groups of NGT, IGT and T2DM. Fasting plasma glucose(FPG)and 2h postprandial plasma glucose (2hPG) after OGTT, lipid profile and BMI were measured. Results Both fasting and 2h postprandial plasma apelin had significant differences in these groups (P<0.05,or P<0.01). The overweight and obese subgroups in the IGT group and diabetes group had higher apelin levels than their counterpart subgroups in the NGT group. BMI, FPO, systolic blood pressure(SBP) were independent influencing factors for apelin (P<0.05 ,or P<0.01). Conclusions Plasma apelin level is related to obesity and type 2 diabetes.

Objective To understand the mastery situation of the knowledge about common infectious diseases among the prima-ry and middle school students,in order to provide the evidence for the prevention and treatment of infectious diseases.Methods The stratified random cluster sampling method was adopted.The survey was performed by the questionnaire form.The data were analyzed by the Chi square test,logistic regression model in the SPSS17.00 statistical software.Results Among the primary and middle school students in Chongqing,the students mastering 75% of the basic knowledge about infectious diseases accounted for 24.6% of the total respondents (P<0.01).From the view of the distribution of disease entities,the top six diseases with the awareness rate of less than 60% were hepatitis B,bacterial dysentery,cholera,measles,pinworm and rabies respectively(P<0.01), whose awareness rates are under 60%(P<0.01).As for the level of mastery among different grades,the senior middle school students had a better knowledge of tuberculosis,flu,SARS,AIDS,hepatitis B,poliomyelitis,etc(P<0.01).Comparatively,the pri-mary school students grasped the knowledge of hand-foot-and-mouth disease and pinworm better(P<0.01).Conclusion The pri-mary and middle school students have a low awareness rate of infectious diseases.Pertinently strengthening the popularization of the knowledge about infectious diseases is the powerful measure for reducing the occurrence of infectious diseases and promote the healthy development of students.

Objective:To study the optimal process of reflux extraction for lignans from Acanthopanax sessiliflorus roots. Methods:Sesamin as the reference substance, a colorimetric method was used to detect the absorption value of the samples at 558 nm to calculate the content directly. The extraction time, the extraction times and the volume of extraction solvent were applied to optimize the extrac-tion conditions for total lignans by orthogonal experiment. Results:The absorbance had a linear relationship with the amourt of sesamin within the range of 10. 6-53. 0 μg·ml-1(r=0. 999 7). The average recovery of sesamin was 102. 2%(RSD=1. 6%, n=6). The content of total lignans (measurement by sesamin) in the extracts was 10. 0 mg·g-1. The optimum reflux extraction conditions were as follows:adding 40-fold 50 % methanol, extracting once for 30 min. Conclusion:The UV method for determining the total lignans is feasible, stable and reliable as well as precise, and the optimal extraction process is reasonable.

Objective To explore the clinical significance of prenatal ultrasound examination in diagnosing twin reversed arterial perfusion sequence (TRAP). Methods This was a retrospective study on 5 cases of TRAP sequence conifrmed by prenatal ultrasound and clinical method. The clinical data and ultrasound images were analyzed. Cases were collected at Hubei Maternal and Child Health Hospital from 2001 January to 2013 February. Results Four-iffths of TRAP were not corrected diagnosed and another one was misdiagnosised as asymmetrical conjoined twins in early pregnancy. Five cases of TRAP were correctly diagnosed during the second trimester. Sonographic ifndings of ifve acardia without blood lfow were as follows:(1) All acardias had no blood perfusion in body and umbilical cord, were absence of the fetal head (acephalous) and heart (acaidia), without skin edema, and a linear object resemble as umbilical cord extend from umbilical region of acardia to plcenta could be seen. Four (case 2-5) had lower limbs or dysplasia of lower limbs (two had spine), and one (case 1) had an irregular mass with bone. (2) Four pump twins had no obvious abnormity, while one had two clubfeet (case 2). Three died in uterus, one underwent induced labor due to oligohydramnios and heart dysfunction, and another one survived. Prenatal ultrasound images were consistent with MRI, X-ray examination, autopsy and postnatal neonatal examination results. Conclusions Acardia without blood lfow which was generally misdiagnosed as single gestation in utero can be diagnosed according to the special disformity of acardia and the linear umbilical cord extend from umbilical region to placenta, besides, it still need to strengthen monitoring the pump twin even if there was no blood perfusion to acardia.
