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.

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.

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 investigate the abnormal region of gray matter and distribution in patients with Parkinson’s disease (PD),and explore the brain structural changes closely related to mild cognitive impairment(MCI).Methods 20 cases of PD-MCI, 1 7 cases of PD-nMCI and 20 normal controls (NC)were examined by 3D-T1 WI brain volume sequence.The data of three groups were analyzed using voxel-based morphometry(VBM)based on SPM8 to generate gray matter map.Results Compared to NC,decreased gray matter volume in PD-nMCI was observed in the right temporal lobe,including the middle temporal gyrus,inferior temporal gyrus,and right fusiform gyrus,uncus and left superior temporal gyrus.Compared to PD-nMCI,decreased gray matter volume in PD-MCI was observed in the bilateral midfrontal gyrus,inferior frontal gyrus,left precentral gyrus,right midtemporal gyrus,superior temporal gyrus,bilateral insular,and right cuneus,lingual gyrus,posterior cingutate.Conclusion Decreased gray volume in PD-nMCI is mainly located in the right temporal lobe and right uncus.With occurrence of MCI,abnormal brain regions are gradually extended.Gray matter atrophy in the bilateral midfrontal gyrus,inferior frontal gyrus,and left precentral gyrus are related to the MCI.

Objective To compare the clinical efficacy of herbal ion application and penetration therapy applied in the dog days, or in both of the dog days and coldest days for the treatment of recurrent respiratory tract infection (RRTI) in children. Methods This intervention was designed as a multi-center, randomized, single-blind, repeated-measurement design. A total of 240 RRTI children were randomly divided into Sanfu group (N=120, herbal ion application and penetration therapy applied in the dog days) and Fujiu group (N=120, herbal ion application and penetration therapy applied in both of the dog days and coldest days). Each group was treated for one year and then was followed up for one year. Before and after the treatment, we observed the frequency of respiratory tract infection, the period of onset, signs and symptoms of traditional Chinese medicine (TCM), and detected the salivary secretory immunoglobulin A (sIgA) at different time points. Results (1) The therapeutic effect of Fujiu group was better than that of Sanfu group, and the difference was significant (P<0.05). (2) The frequency of respiratory tract infection was reduced, the period of onset was shortened, and TCM signs and symptoms were improved in both groups, and the effect of Fujiu group was superior to that of Sanfu group (P<0.05). (3) Salivary sIgA showed a continuous upward trend in Fujiu group while a mild downward trend in Sanfu group at different time points (P<0.05). Conclusion Herbal ion application and penetration therapy applied in both of the dog days and coldest days shows better effect for the treatment of children RRTI than that applied only in the dog days.

Aim To investigate the effects of diallyl di-sulfide( DADS) on G2/M arrest in Chk1/MGC803 and Chk2/MGC803 cells so as to establish stable human gastric cancer MGC803 cells with overexpression of Chk1/2 gene. Methods The colony formation, flow cytometry, RT-PCR and Western blot were used to de-tect the proliferation, cell cycle, and expression of Chk1/2 mRNA and protein, p-Chk1/2, CDC25C and cyclinB1, respectively. Results The colony formation showed that the colony forming efficiency in Chk1/MGC803 and Chk2/MGC803 cells treated by 30 mg· L-1 DADS was lower than in control group and vector group ( P <0. 05 ) . Flow cytometry demonstrated that 41. 3%, 57. 4%, 68. 9% and 42. 9% of G2/M cells in Chk1/MGC803 were increased than in MGC803 and Chk2/MGC803 , respectively after treated by DADS in 12,24, 36 and 48 h(P <0. 05). At the same time, RT-PCR disclosed that expression of Chk1 and Chk2 mRNA had no marked change. Western blot showed that total proteins of Chk1 and Chk2 and p-Chk2 had invisible change, but expression of p-Chk1 was up-reg-ulated, and CDC25C and cyclinB1 were down-regula-ted time-dependently in Chk1/MGC803 cells ( P <0. 05 ) . Conclusion DADS arrests MGC803 cells at G2/M by increasing p-Chk1 expression to cause down-regulation of CDC25C and cyclinB1 simultaneously.

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.
