The influence of Chang-Bai Xin kui(长白新圭) on the acid ?-naPhthyl acetate esterase(ANAE) positive lymphocytes was studied by using ANAE as a cytochemical marker.S180 cells ef ascites tumor were inoculated into the mice in experimental and control group. 3 days later, 0.8mg/0.2ml of Chang-Bai Xin Kni was injected peritoneally into the mice in experimental group everyday in 7 days. Eaeh of the two groups has its own self control.The experimental results show that there is no significant differences in total numbar of ANAE positive lymphoctes between the two groups and all self-controls.But after 7 days of injecting the drug, the granular pattern and scattered granular pattern of lymphoctes were increased significantly(P

Normal lung tissues are inevitably exposed to X-ray in thoracic radiotherapy,causing radiation-induced lung injury (RILI).The main pathological manifestations include the accumulation of inflammatory cells,release of cytokines,accumulation and proliferation of fibroblasts,and excessive deposition of alveolar interstitial collagen in the irradiated region.RILI severely affects the treatment compliance and quality of life and even threatens the life in the patients receiving radiotherapy.In recent years,numerous studies have found that Th1/Th2 imbalance is closely associated with the development and progression of RILI,and the cytokine network plays an executive role in the progression of RILI.Therefore,restoring the Th1/Th2 balance in vivo may provide a new way to prevent and treat RILI.

Objective Recent studies suggest that the red blood cell distribution width ( RDW) may play a role in the diag-nosis and treatment of cardiovascular disease.The aim of this study was to investigate the correlation of red blood cell distribution width (RDW) with cardiovascular events in patients with Acute ST-segment elevation myocardial infarction (ASTEMI) in order to provide the basis for improving the diagnosis level and therapeutic effect. Methods Retrospective study was made on the clinical data of 189 patients with ASTEMI enrolled in Sichuan Provincial People′s Hospital from January 2013 to March 2014.The survival rates of patients with ASTEMI with different RDW were estimated by Kaplan-Meier and compared by Log-rank test and the prognosis factors were inves-tigated by Cox proportional hazard regression model. Results 97 patients′RDW levels were more than 13.7% and 92 patients′RDW levels were less than or equal to 13.7% in 189 ASTEMI patients. The hs-CRP, BNP, LVEF and HDL-C were significantly different be-tween two groups (P<0.05).The rates of recurrent myocardial in-farction, heart failure, sudden death cardiac in patients with highRDW were higher than that in patients with low RDW (22.7%vs 8.7%, 27.8%vs 10.9%, 15.5%vs 5.4%)(χ2 =6.915, 8.632, 5.019, P<0.05) .There were 60 patients with high RDW who experienced cardiovascular events and the 1-year cardiovascular event-free survival rate was 38.1%, and 20 patients with low RDW cardiovascular events was 79.3% in follow-up period (χ2 =30.959, P<0.001).Multivariate cox regression showed that age>65 (HR=2.43, 95%CI:1.09~5.44) and RDW>13.7%(HR=2.20, 95% CI:1.10~4.43) were risk prognostic factors. Conclusion There is a certain correlation between RDW and cardiovascular e-vents in patients with ASTEMI.The ASTEMI patients with high RDW hold higher risk of cardiovascular events and poorer prognosis.

Objective The objective of this study was to provide a way to assess the nutritional status of patients and to afford targeted nutritional supports during the radiotherapy on the basis of the laboratory parameters related to nutrition and chest muscle size in lung cancer patients at the different time.Methods The laboratory parameters were obtained in a cohort of 160 lung cancer patients who received thoracic radiotherapy in our department from March 2012 to November 2015.Fourteen patients who had complete chest CT scan images during radiotherapy were selected to evaluate chest muscles volume.The Chest muscles and its volume were delineated and calculated by CT scan images.Results The levels of(Hemoglobin)HGB,lymphocyte,total protein and albumin were decreased in different degrees during and after radiotherapy,which had the positive correlation with the number and doses of radiotherapy(P<0.05).The changes of hemoglobin and lymphocyte were more obviously among them;these indicators began to recover after 5 weeks of radiotherapy.Chest muscle volume was also the same as the trend of hematological indicators(P>0.05).Conclusion Cancer patients were prone to suffer from malnutrition during radiotherapy.The intake of energy and protein was less than the requirements.We should always take the nutritional status of patients into account and provide targeted nutritional support to improve treatment tolerance and quality of life of patients during radiotherapy.

Objective To explore the value of two-dimensional strain echocardiography for quantitative assessing the change of regional left ventricular myocardial function in rats following acute myocardial infarction. Methods Sixty Wistar rats were randomly divided into two groups. The study group consisted of 50 rats with occlusion of LAD for 30-45 minutes and the sham-operated group consisted of 10 rats without occlusion of LAD. Echocardiography were performed before operation, which was defined as baseline, and 1 week, 4 weeks and 8 weeks after operation. Left ventricular internal diameter at diastole ( LVIDd) and systole < LVIDs), fractional shortening( FS), ejection fraction (EF) and left ventricular mass(LVM) were measured by anatomical M-model echocardiography. High frame rate two-dimensional images were recorded in the left ventricular short-axis views at the papillary muscle level. Peak systolic radial strain(PRS) and circumferential strain(PCS) of each segment were measured using 2-dimensional strain software. The rats were sacrificed and the infarcted size of each segment was measured using triphenyl tetrazolium chloride (TTC) after echocardiography was performed. Fibrosis of left ventricular myocardium was displayed using Van Gieson stain in 1 weeks after infarction. Results Based on the TTC findings,the left ventricle of the study group was divided into three regions:infarcted,peri-infarct and remote myocardial regions. Van Gieson stain showed fibrosis existed in all the three regions. Compared with baseline and sham-operated group, PRS and PCS of infarcted, peri-infarct and remote myocardial regions of the study group significantly decreased within 1 week after operation ( P <0. 01) and persisted for 8 weeks. PCS and PRS of infarcted, peri-infarct and remote myocardial regions of the study group in 4 weeks and 8 weeks after operation showed no significant difference when compared with those in 1 week after operation ( P >0. 01). Compared with baseline and sham-operated group,LVIDd,LVIDs and LVM of study group all increased significantly ( P <0. 05) in 4 weeks and 8 weeks after operation,and FS and EF reduced significantly ( P <0. 05). Two-dimensional strain obtained in interobserver and intraobserver both showed high agreement. Conclusions Two-dimensional strain echocardiography can assess regional function of myocardium with different perfusion in rats following acute myocardial infarction, and provides a sensitive and reliable method to follow up the process of left ventricular remodeling after myocardial infarction.

5-FU-resistance in HCT116/5-FU cells.

The effects of combined RNA interference (RNAi) of human telomerase RNA (hTR) and human telomerase reverse transcriptase (hTERT) genes on telomerase activity in a bladder cancer cell line (BIU-87 cells) were investigated by using gene chip technology in vitro with an attempt to evaluate the role of RNAi in the gene therapy of bladder transitional cell cancer (BTCC). Three TR-specific double-stranded small interfering RNAs (siRNAs) and three TERT-specific double-stranded siRNAs were designed to target different regions of TR and TERT mRNA. The phTR-siRNA, phTERT-siRNA, and the combination of both plasmids phTR+phTERT-siRNA were transfected into BIU-87 cells. The expression of hTR and hTERT mRNA was detected by quantitative fluorescent reverse transcription-polymerase chain reaction, and a telomeric repeat amplification protocol was applied to detect telomerase activity. Growth inhibition of BIU-87 cells was measured by MTT assay. Gene chip analysis was performed to evaluate the effects of the combined RNAi of hTR+hTERT genes on telomerase activity and growth of BIU-87 cells in vitro. The results showed that the expression of hTERT and hTR mRNA was inhibited by pRNAT-hTERT-III, pRNAT-hTR-III, and pRNAT-hTR-III+hTERT-III in BIU-87 cells. The inhibition efficiency of pRNAT-hTERT-III, pRNAT-hTR-III, pRNAT-hTERT-III+pRNAT-hTR-III was 67% for TERT mRNA, 41% for TR mRNA, 57% for TR mRNA and 70% for TERT mRNA in BIU-87 cells respectively. The growth of BIU-87 cells was inhibited and telomerase activity was considerably decreased, especially in the cells treated with combined RNAi-hTR and -hTERT. Gene chip analysis revealed that 21 genes were down-regulated (ATM, BAX, BCL2, BCL2L1, BIRC5, CD44, CTNNB1, E2F1, JUN, MCAM, MTA1, MYC, NFKB1, NFKBIA, NME4, PNN, PNN, SERPINE1, THBS1, TNFRSF1A, and UCC1). The results indicated that hTR-siRNA and hTERT-siRNA, especially their combination, siRNA hTR+hTERT, specifically and effectively suppressed the expression of both hTR and hTERT mRNA and telomerase activity. Molecular biological mechanism by which combined siRNA-TR and -TERT inhibited telomerase activity and growth of BIU-87 cells in vitro may involve the down-regulation of the 21 genes.
