OBJECTIVE: To investigate the effect of arsenic trioxide (As2O3) combined with cisplatin on expression of RASSF1A in nude mice with human nasopharyngeal carcinoma xenograft. METHOD: The models of human poorly differentiated nasopharyngeal carcinoma in nude mice were established and randomly divided into four groups, control group (NaCl group), As2O3 group, DDP group and As2O3 + DDP group. The expression of RASSF1A mRNA and protein were detected by Real-time RT-PCR and immunohistochemistry respectively. The methylation rate of RASSF1A promoter CpG islands was analyzed by HRM. RESULTS: Experimental groups could obviously inhibit the growth of tumor and up-regulate the expression of RASSF1A. The methylation rate of RASSF1A in transplanted tumors in experimental groups was lower than the control group. Especially As2O3 combined with DDP were superior to the single drug use. CONCLUSION As2O3 inhibits the growth of human nasopharyngeal carcinoma cell strain CNE2 xenograft in nude mice and increases mRNA expression of RASSF1A. As2O3 inhibits the malignant phenotypes of human nasopharyngeal carcinoma cells and reverses hypermethylation of RASSF1A.

Objective To discuss the clinical application value of 256-slice helical CT 3D-imaging in guiding interventional occlusion therapy for patent ductus arteriosus (PDA).Methods A total of 40 patients with sonography-proved PDA were randomly divided into group A (angiography group) and group B (CT-guided group) with 20 patients in each group.For the patients of group A,occlusion of PDA was performed based on the intraoperative angiography findings;and for the patients of group B,occlusion of PDA was carried out according to CT examination results.Intraoperative cardiac ultrasound monitoring was adopted and the curative effect was evaluated.Results The morphology of PDA demonstrated on CT 3Dimaging in group B was highly consistent with the configuration of PDA displayed on intraoperative angiography in group A.The most narrow diameters of PDA in group B and group A were (3.88±1.59) mm and (3.63±1.41) mm respectively,and the lengths of PDA in group B and group A were (6.1±1.06) mm and (6.82±0.74) mm respectively;the differences between the two groups were not statistically significant (P＞0.05).The time spent for surgery in group B and group A was (34.3±9.11) min and (17.33±5.81) min respectively,and the intraoperative X-ray radiation doses in group B and group A were (33.93±11.0) mGy and (66.48±9.77) mGy respectively;the differences between the two groups were statistically significant (P＜0.001).In group B,the preoperative X-ray radiation dose from CT examination was (119.79±29.45) mGy,when it was added to the intraoperative X-ray radiation dose the total cumulative radiation dose of group B was strikingly higher than that of group A.Conclusion Contrast-enhanced 256-slice helical CT scan and 3D-imaging technique can replace intraoperative angiography to get accurate anatomical imaging information of PDA,which are very helpful for the performance of interventional occlusion of PDA,meanwhile,it can effectively reduce the damage to the punctured artery and shorten the operation time.However,the radiation dose is a factor that should be taken into consideration.(J Intervent Radiol,2017,26:206-209)

OBJECTIVE:To explore the present situation of scientific research of clinical pharmacists in domestic third-grade class A hospitals,and discuss its feasible research ideas. METHODS:Questionnaire was conducted for the scientific research situa-tion of clinical pharmacists who obtained the certification in domestic 63 third-grade class A hospitals,the questionnaire data was collected,and data was statistically analyzed by using IBM SPSS Statistics 22.0 software. RESULTS:Totally 315 questionnaires were sent out,282 were effectively received,with effective recovery of 89.52%. In terms of attitude to scientific research,propor-tion of the surveyed clinical pharmacists who thought it was quite necessary and necessary was more than 70%;except for academ-ic degree(P<0.05),the different gender,age and job title did not cause the differences in scientific research attitude(P>0.05). In terms of the present situation of scientific research,achievements of them were relatively simple,thinking the biggest difficulty was insufficient of experiment condition;there was significant difference in the numbers of authorized patents in recent 5 years by different gender (P<0.05),the numbers of applications for approved funds,authorized patents and paper published in recent 5 years by different academic degrees(P<0.05),as well as the numbers of applications for approved off-campus funds(title also re-lated to the number of hospital funds)and the numbers of paper published in domestic magazine in recent 5 years by different ages and job titles (P<0.05). In terms of direction of scientific research,most of surveyed clinical pharmacists thought they should strengthen communicate with physicians and look for the breakthrough point,they also thought the optimal one was clinical re-search;the direction selection was basically similar no matter the gender,academic degree,age and job title(P>0.05). In terms of ability enhancement,the surveyed pharmacists thought liter-ature review,evidence-based literature/experimental interpreta-tion and foreign language reading were the abilities most need to be enhanced;except for gender,academic degree,age andjob title showed similarity in enhancing the literature review,evidence-based literature/experimental interpretation ability (P>0.05),while there were significant differences in enhancing foreign language reading ability by different gender,academic degree, age and job title (P<0.05). CONCLUSIONS:Clinical pharmacists show certain differences in the attitude to scientific research, present situation and direction of scientific research,and ability enhancement because of different gender,academic degree,age and job title,but there are also common. In order to improve the competence of scientific research and promote the discipline devel-opment of clinical pharmacy,pharmacy administrator in hospital should improve the academic degree and job title on clinical phar-macists and provide necessary advanced scientific platform and pertinent training at the same time. Additionally,except for the ratio-nal drug use,evidence-based pharmacy and pharmacoeconomics,clinical pharmacists can find new breakthrough point from phar-maceutical care,drug treatment decisions,translational medicine and medicine large data.

This paper focuses on a differential equation logistic model simulating tumor growth. We design a kind of tumor dynamic growth model with one-dimensional cellular automata. A discrete logistic model is developed from the continuous logistic model. Based on others' work, we design discrete mathematical growth dynamic model with cellular automaton. In terms of discrete model, we design stochastic evolving rules of cellular automaton. And this paper simulates the tumor growth dynamic model with cellular automata. The theoretic analysis and results of cellular automaton model are in agreement with data from the ideal differential equation logistic growth of cancer.

Objective. To understand drug susceptibilities to common antibacterials, resistance mechanism to β-lactams and quinolones and the clonal spread of resistant stains of Haemophilus influenzae (H. influenzae) and Haernophilus parainfluenzae (H. parainfluenzae) isolated from some hospitals in Shanghai. Methods The in vitro antimicrobial susceptibilities to 13 antibacterials, such as ampicillin, of 156 Haemophilus strains collected from 5 hospitals of Shanghai in 2006 were tested by agar dilution method. The β-lactamase production was determined by chromogenic cephalosporin test. TEM and ROB type of β-lactamase genes and quinolone resistance determining regions (QRDR) of ciprofloxacin-resistant strains were detected by polymerase chain reaction (PCR) amplification. The homology of H. influenzae strains were analyzed by enterobacterial repetitive intergenic consensus (ERIC)-PCR. Results The susceptible rate of 109 strains H. influenzae to ampicillin was 74.3%, while those to ampicillin-sulbactam, cephatosporins and fluoroquinolones were all 100.0%. The β-lactamases-producing rates of 109 strains H. influenzae and 47 strains H. parainfluenzae were 25.7% and 19.1% (χ2=0.776,P=0.378), respectively. TEM gene was detected in all β-lactamases-producing strains. Of 109 H. influenzae isolates, only one was resistant to ciprofloxacin, and Ser84Leu mutation was detected in gyrA gene and Gly206Arg mutation in parC gene. The results of ERIC-PCR showed that 106 H. influenzae strains were clustered into 73 groups with similarity level of 85%. Conclusions Clinical isolates of H. influenzae from hospitals in Shanghai remain highly susceptible to common antimicrobial agents except ampicillin. TEM type of β-lactamase production is the main ampicillin-resistant mechanism of the tested stains. The clonal spread of H. influenzae, including ampicillin-resistant strains, is not prevalent.

Objective To evaluate the effects,hemodynamies and hepatic functional reserve of a combined procedure of modified pmximal splenocaval shunt and pericardial devascularlzation (PCDV) in the treatment of portal hypertension.Methods From 1997 to 2007,a total of 255 patients with cirrhotic portal hypertension received combined (135 cases) or PCDV procedure (120 cases,) in our hospital.The clinical results were retrospectively analyzed.Changes of hemodynamics of the portal venous system were studied by Doppler color flow imaging and intraoperative free portal pressure (FPP) measurement.The hepatic functional reserve was evaluated by indocyanine green (ICG) retention ratio and functional hepatic flow(FHF).Results Postoperative mortality was 2.2% in combined group and 4.3% in PCDV group.The long term rebleeding rate was 5.5%as revealed by follow-up in combined group,which was significantly lower than that in PCDV group of 14.1%(P<0.05).The incidence of encephalopathy was 6.4%and 5.4%in combined group and PCDV group respectively(P>0.05).The 1-,3-,5-and 10 year-survival rates were 96.4%,90.0%,81.3%and 62.5% in combined group and 95.7%,86.7%,75.0%,57.1%in PCDV group.In combined group,the FPP、PVF and FHFwere(32.0±1.5)cm H_2O、(880±260)ml/min and(430±1 80)ml/min respectively,a significant decrease when compared with preoperative parameters (P<0.05),while R_(15) (30%±4%)increased (P<0.01).The similar results were observed in PCDV group postoperatively (P<0.05).Compared to PCDV group,the decrease of FPP in combined group was more significant(P<0.05),but the PVF,FHF and R_(15) were not significantly different (P>0.05).Conclusions The combined procedure is safe and effective in treatment of portal hypertension with better clinical outcome,moderate homodynamic changes and good maintenance of hepatic functional reserve.
