Objective To investigate the dynamic change of serum Hcy level in patients with non-small lung cancer when under-going chemotherapy,and to study the value of monitoring serum Hcy for chemotherapy efficieney in non-small-cell carcinoma.Meth-ods In our study,we enrolled 62 patients with non-small-cell carcinoma when undergoing chemotherapy.The concentrations of ho-mocysteine,carcino-embryonic antigen and cytokeratin 1 9 fragments were detected,and then these results were analyzed by statisti-cal methods.Results Compared with before treatment,the serum homocysteine,carcino-embryonic antigen and cytokeratin 1 9 frag-ments levels in patients who had effective response decreased.After 2 courses of chemotherapy,the levels of the three markers were significantly lower than those detected before chemotherapy (P <0.05).But at the end of the first course,the serum hcy level was significantly lower than that detected before chemotherapy.There was no significant difference in the levels of the serum three markers in non-responders between before and after chemotherapy (P >0.05).The positive rates of the three markers were statisti-cally significant between single lung squamous cell carcinoma and adenocarcinoma of the non-small-cell carcinoma.Conclusion The detection of the dynamic changes of serum Hcy in patients with non-small-cell carcinoma when undergoing chemotherapy is useful in evaluating the effect of chemotherapy and tumor activity.

Objective To assess the expression patterns of apoptosis-related genes in human pancreatic cancer cells (Patu-8988)induced by Kanglaite (KLT), a novel anti-cancer botanical product. Methods The apoptosis of Patu-8988 cells was determined by flow cytometry with Annexin V-FITC and propidium iodide staining. A human apoptosis microarray containing 96 cDNA fragments was used to detect gene expressions, and followed by Western blot analysis to confirm changes in expression of selected gene products. Results KLT induced apoptosis of Patu-8988 cells in a time-dependent manner. cDNA microarray analysis identified 5 down-regulated genes and 12 up-regulated genes (more than three fold) in the first 24 h as a consequence of treatment. Western blot performed for P53, Bcl-2, Bax and Caspase-3 were consistent with the microarray results. The enhanced activity of Caspases-3 was evidently verified by the cleavage of the 89?103 form of poly ADP-ribose polymerase. Conclusion KLT could alter the expression profile of apoptosis- related genes in human pancreatic Patu-8988 cancer cells, which provides valuable insight into the tentative signaling pathways mediating the outcome of KLT-induced apoptosis.

Rat hepatic oval cell model was induced by hyperglycemia and streptozotocin in vivo. Expression of insulin and mRNA expression of pancreatic transcription factors(Nkx6.1, PDX-1) were carried out. It showed that under high glucose, liver tissues were positive for insulin staining, the expression of Nkx6.1 and Pdx-1mRNA was significantly enhanced, and insulin-1mRNA was found to be expressed. The result suggests that under high glucose, hepatic oval cells can differentiate into insulin-producing cells.

OBJECTIVETo investigate the effects of Zuogui pill, Yougui pill and the relative compositions on the differentiation towards germ cells of stem cells.

METHODThe rat drug sera for Zuogui pill, Yougui pill and the common composition of Zuogui pill and Yougui pill were prepared respectively as the experimental drugs; the mouse embryonic stem cell 1B10 (MESC-1B10) was used as the representative of stem cells; the above rat drug sera were used to intervene MESC-1B10 and the process was traced by microscopy imaging; after 72 h of the intervention, the RNAs were extracted from the different intervened MESC-1B10, cDNAs were synthesized immediately and finally the Real-time quantitative PCR (qPCR) was used to measure the expression patterns of the 10 reproductive-differentiation-related genes for each intervention.

RESULTThe rat drug serum of Zuogui pill (ZGW-RS) significantly up-regulated Oct-4 and SCP3 and significantly down-regulated GDF-9 and Stra8; the rat drug serum of Yougui pill (ZGW-RS) significantly up-regulated Oct-4, GDF-9, Mvh and SCP3 and significantly down-regulated Stra8, Itga6 and Itgb1; the rat drug sera for the common composition of Zuogui pill and Yougui pill (ZGWYGW-RS) significantly up-regulated Oct-4, SCP3 and ZP3 and significantly down-regulated GDF-9, Stra8, Itga6 and Itgb1.

CONCLUSIONZGW-RS can initiate the change towards meiosis, but can not start the reproductive differentiation of MESC-1B10; YGW-RS can initiate the change towards meiosis, and can also start the reproductive differentiation of MESC-1B10 towards female germ cells; ZGWYGW-RS can initiate the change towards meiosis, and can lightly start the reproductive differentiation of MESC-1B10 towards female germ cells but the inductive effect is smaller than YGW-RS. The experimental results, on one hand, strengthen the knowledge about the influence of the relative compositions of Zuogui pill and Yougui pill on the reproductive differentiation of stem cells, on the other hand, help to explain the mechanism of the treatment of the infertility by Zuogui pill and Yougui pill.

Objective To evaluate the diagnostic value of endoscopic ultrasound guided fine needle aspiration (EUS-FNA) in combination with flow cytometry (FCM) in lymphoma.Methods From January 2011 to December 2011,the cases of suspicious lymphoma with EUS-FNA examination at Shanghai Ruijin Hospital were retrospectively analyzed.The final diagnosis was according to pathological diagnosis of specimen from the surgery and follow up results.The sensitivity,specificity and accuracy of EUS-FNA combined with FCM in lymphoma diagnosis were initially analyzed.Results A total of 14 suspicious lymphoma patients were collected,eight cases were diagnosed as lymphoma by pathological examination of specimen from the surgery or.tissue from aspiration,four cases were non-lymphoma lesions and two cases still had no final diagnosis.The sensitivity and specificity of FCM alone in lymphoma diagnosis were 4/8 and 4/4 respectively.Six cases of lymphoma were detected by EUS-FNA with FCM.The sensitivity,specificity and accuracy of EUS FNA combined with FCM were 6/8,6/6 and 10/12 respectively.Conclusion EUS-FNA combined with FCM has better diagnostic value in lymphoma,especially for gastrointestinal lymphoma and those surrounding deep lesions.

ObjectiveTo observe the change of cardiac function after acute myocardial infarction (AMI) in rabbit model,and to study MRI characteristics of left ventricular remodeling (LVR).Methods Forty-five japanese white rabbits underwent chest-opening coronary artery ligation surgery to obtain rabbit myocardial infarction model The animals were scanned on a 1.5 T MR scanner ( GE Healthcare,Chalfont St.Giles,UK) at six time-points as surgery,1,2,4,6,8 weeks after surgery. Cardiac function parameters were measured,including left ventricular end diastolic volume ( EDV ),stroke volume ( SV ),ejection fraction (EF),peak ejection rate ( PER ) and peak firing rate (PFR).At each time point,5 rabbits were randomly selected and performed re-thoracotomy to obtain heart specimen.Each specimen was examined by MRI with the diffusion tensor imaging ( DTI ).The value of ADC and fractional anisotropy (FA) were collected. Cardiac function data sets of different time points were analyzed using repeated measures data of ANOVA.The FA and ADC values of infarction myocardium set of different time points or different parts of the myocardium were analyzed using one-way ANOVA. The average was compared statistically between two adjacent groups using LSD-t test. Results Left ventricular EDV increased in progress with the time.It was increased from ( 2.21 ± 0.35 ) ml preoperatively to ( 3.15 ± 0.57 ) ml 8-week postoperatively.But the difference was not statistical significant ( F =1.384,P =0.220).EF was decreased from(57.31 ± 11.11 )％ to( 34.71 ± 8.72 )％.It dropped significantly and the difference was statistically significant (F =27.134,P =0.001 ).EF showed a downward trend with the increase of EDV.By linear regression analysis,an equation was set up with y =- 5.58x + 57.7 ( F =8.855,P =0.005 ).On the other hand,PER showed a progressive decline from (27.31 ± 13.06) ml/s to ( 17.31 ± 6.41 ) ml/s ( F =2.105,P =0.037 ),and PFR decreased from ( 23.79 ± 14.15 ) ml/s to ( 12.07 ± 6.91 ) ml/s ( F =2.366,P =0.011 ).FA value decreased from 0.442 ±0.093 to 0.107 ±0.037( F =12.61,P =0.001 ),and ADC valueshowed upward trend from (5.07 ± 1.15) ×10-4 mm2/s to(6.39 ±0.78) ×10-4 mm2/s (F=4.166,P =0.022 ).FA values of infarct,adjacent and remote region were 0.201 ± 0.049,0.316 ± 0.127 and 0.323 ± 0.117 respectively( F =3.896,P =0.004 ),and the ADC values in these regions were (6.19 ± 1.78 ) ×10 -4,(5.44 ± 2.63 ) × 1 0 -4,(5.29 ± 2.02 ) × 10 -4 mm2/s respectively ( F =3.248,P =0.018 ).FA and ADC values were significantly different between the infarct region and adjacent region ( t =7.327,P =0.001 ;t =3.292,P =0.005,respectively),but there was no significantly different between adjacent region and remote region ( t =1.024,P =0.129 ; t =1.467,P =0.164,respectively ).ConclusionsMRI measurement of parameters of cardiac function can be used to monitor the process of left ventricular function remodeling after AMI.The process of micro-structural remodeling of myocardium can be reflected by DTI.MRI provides a feasible imaging modality for LVR after AMI.

Objective To explore the technique of maximum entropy model for extracting Oncomelania hupensis snail habi?tats in Poyang Lake zone. Methods The information of snail habitats and related environment factors collected in Poyang Lake zone were integrated to set up the maximum entropy based species model and generate snail habitats distribution map. Two Land?sat 7 ETM+remote sensing images of both wet and drought seasons in Poyang Lake zone were obtained,where the two indices of modified normalized difference water index(MNDWI)and normalized difference vegetation index(NDVI)were applied to ex?tract snail habitats. The ROC curve,sensitivities and specificities were applied to assess their results. Furthermore,the impor?tance of the variables for snail habitats was analyzed by using Jackknife approach. Results The evaluation results showed that the area under receiver operating characteristic curve(AUC)of testing data by the remote sensing?based method was only 0.56, and the sensitivity and specificity were 0.23 and 0.89 respectively. Nevertheless,those indices above?mentioned of maximum en?tropy model were 0.876,0.89 and 0.74 respectively. The main concentration of snail habitats in Poyang Lake zone covered the northeast part of Yongxiu County,northwest of Yugan County,southwest of Poyang County and middle of Xinjian County,and the elevation was the most important environment variable affecting the distribution of snails,and the next was land surface tem?perature(LST). Conclusions The maximum entropy model is more reliable and accurate than the remote sensing?based meth?od for the sake of extracting snail habitats,which has certain guiding significance for the relevant departments to carry out mea?sures to prevent and control high?risk snail habitats.

1.The external features and arterial supply of the papillary muscles of the leftventricle were studied in 54 human,52 dogs' and 110 rabbits' hearts.Radiopaquemedium or Chinese ink were injected into coronary arteries.After injection,arter-iography of some hearts were taken,and serial celloidin sections of the papillarymuscles of other hearts were made.The diameters of the papillary arteries and thedensity of the vessels were measured.2.The papillary muscles could be divided into three patterns,depending on theextent of their attachment to the ventricular wall and the relative length of theirfree part protruding into the ventricular cavity.The three patterns were as follows:(1)The attached type,the papillary muscle was largely adherent to the sucbjacentventricular myocardium,with only one third or less of its length protruding into theventricular cavity(34% in human hearts,100% in dogs' and 38% in rabbits').(2)The free type,the free end of the papillary muscle was one half of its length ormore(28% in human hearts,10% in rabbits').(3)The intermediate type,thelength of the free protruding part of the papillary muscle was intermediate between(1)and(2)(38% in human hearts,52% in rabbits').3.In the human and the dogs' hearts the anterolateral papillary muscle receivedbranches from the anterior descending artery and the diagonal left ventricularbranches or the left circumflex artery;while in the rabbits' it received branchesmainly from the anterior branches of the left ventricular artery.The posteromedialpapillary muscle received a variable supply from the left circumflex artery and orthe branches of the right coronary artery in the dogs' hearts and in the human hearts,while in the rabbits' hearts,it mainly received branches from the posteriorbranches of the left ventricular artery.4.The arrangement of the arterial vasculature of the papillary muscle seemedto be related to the different patterns of the papillary muscles.The free typereceived a large central artery which coursed through the entire papillary muscle toits apex(87.5%).The attached type had a segmental supply of 3～9 long penetrat-ing intramyocardial vessels(94.29%).The intermediate type had a combination ofboth types of vascular arrangement(98.5%).5.The average diameter of the central arteries was 617.50 ? in human hearts atits entry into the base of the papillary muscle,and 236.05 ? in rabbits.The dia-meters of the segmental arteries were 323.60 ? in human hearts,300.05 ? in dogs',121.78 ? in rabbits' respectively.The diameters of the capillary vessels were 5～8 ?in human hearts,3～6 ? in dogs',2.5～6 ? in rabbits' respectively.The numbersof capillaries that observed in a length of 200? were 15.45 in human hearts,16.2in dogs',19.3 in rabbits'.The specific values of the density of vessels per unitarea were 34.4% in human hearts,34.1% in dogs',56% in rabbits'.
