RESUMEN
The aim of this study is to investigate the effect of the chimeric intron in different directions on the expression of the nerve growth factor (NGF) in recombinant Chinese hamster ovary (CHO) cells. The chimeric intron that contained the splice sequence of the first intron of the human β-globin and the human immunoglobulin heavy chain variable region intron was used. NGF gene was cloned into the expression vectors containing the chimeric intron in the forward or reverse direction, followed by transfecting into CHO cells, and screened under G418 to produce the stable transfected CHO cells. Fluorescence quantitative PCR, ELISA, and Western blotting were performed to detect the recombinant NGF gene expression in CHO cells. The results showed that the chimeric introns could significantly enhance the expression of NGF in recombinant CHO cells. Moreover, the enhancing effect on NGF expression level by the intron in the forward direction showed stronger than that of the reverse direction both at mRNA and protein level. In conclusion, the chimeric intron could increase NGF expression in stably transfected CHO cells and the effect is associated with the direction of the intron insertion.

RESUMEN
OBJECTIVE:To provide reference for the formulation of correct antifungal treatment strategy,and to promote stan-dard use of antifungal agent. METHODS:A retrospective survey was conducted for 138 haematologic patients from May 2013 to May 2014 in a third grade class A hospital,of whom all had used antifungal drugs during hospitalization. We collected all patients' information and analyzed it statistically. RESULTS:Of 138 haematologic patients,3 were proven IFD (all were Candida infec-tion),6 were probable IFD,12 were possible IFD,and 117 were undefined IFD. The positive rates of fungi pathogenic detection, fungal smear,G-test,and GM-test were 15.3%,9.4%,6.4% and 23.4% respectively. 6 kinds of antifungal were used,and vori-conazole had the highest frequency,followed by fluconazole,itraconazole,amphotericin B,caspofungin and micafungin. 62.3%patients used only one kind of antifungal,but 15.9% patients used 2 or more kinds of antifungal. The average medication course was 20.5 days(1 day to 125 days). Irrational drug use showed improper drug selection,unreasonable dose,and replacing antifun-gal with insufficient basis. CONCLUSIONS:The antifungal use in haematologic patients in the hospital is consistent with the re-quirements of guidelines,but there are still some issues as insufficient antifurgal drug treatment course to be further standardized.
RESUMEN
OBJECTIVE:To provide reference for rational use of antibacterial drugs in the clinic. METHODS:In retrospective study,outpatient and emergency antibacterial drugs prescriptions were randomly selected from a hospital during 2013-2014,and then analyzed statistically. DDDs of antibacterial drugs were analyzed by using DDD method. RESULTS:From 2013-2014,the ap-plication rate of antibacterial drugs in the hospital declined substantially from 13.8% to 11.9%,and the rate of irrational use dropped from 2.7% to 1.2%. The application rate of antibacterial drugs was higher in pediatric department,emergency department and urology department;drug cost per capita was higher in infectious department,nephrology department and emergency depart-ment. The application rate of antibacterial drugs in pediatric department decreased greatly in 2014,compared with 2013,maintain-ing about 40%. The application rate of antibacterial drugs in emergency department during Jan.-Sept. in 2014 was lower than corre-sponding period in 2013,and that of the hospital during Jan.-Sept. in 2014 was lower than corresponding period in 2013,but dur-ing Oct.-Dec. in 2014 was slightly higher than corresponding period in 2013. Single type of antibacterial drugs were mainly used in outpatient department,accounting for 91.50% and 90.77% of antibacterial drug prescriptions in 2013 and 2014;two-drug account-ed for 8.44% and 9.11%. The top 3 antibacterial drugs in the list of DDDs during 2013-2014 were roxithromycin,cefuroxime and cefminox. CONCLUSIONS:The use of antibacterial drugs is up to the requirements of Nation Special Rectification Actirity for Clin-ical Application of Antibacterial Drugs in 2013. The prescription comment improve the quality of antibacterial drug prescriptions and rational use index greatly in outpatient department,but the application rate of antibacterial drugs is too high in some depart-ment. There still is irrational use of antibacterial drugs.
RESUMEN
To explore the influence of low light on the synthesis of carotenoids, chlorophyll and the adaptability of transgenic plants with tomato Solanum lycopersicon L. GGPS2 gene, we constructed a vector containing a GGPS2 gene with green fluorescent protein (GFP) as report gene under the control of a cauliflower mosaic virus 35S promoter and introduced it into tobacco Nicotiana tabacum L. cv. Wisconsin 38 by Agrobacterium tumefaciens-mediated transformation. PCR analysis of the DNA from kanamycin resistant tobacco indicated that the transgenic tobacco containing the nptII gene, SlaGGPS2 gene and without contamination of Agrobacterium. We also detected the root tip of kanamycin resistant tobacco showing characteristic fluorescence. The contents of carotenoid, chlorophyll and photosynthesis of transgenic tobacco increased in comparison with wild tobacco after low light treatment. In addition, leaf mass per unit area, total dry weight, ratio of root to shoot in transgenic tobacco were all higher than that of the wild tobacco, which proved that the transgenic tobacco could increase the accumulation of biomass and promote it transport to root. The transgenic tobacco with SlaGGPS2 gene can increase the contents of carotenoid, chlorophyll, enhance the photosynthetic rate, promote the biomass accumulation and its distribution to root. Hence, the transgenic tobacco with SlaGGPS2 gene had increased low light tolerance and the SlaGGPS2 gene maybe can be used in other crops.

Objective: To investigate the absorption and transepithelial transport characteristics of scutellarin and scutellarein in the human colonic adenocarcinoma cell (Caco-2) monolayer model. The influence factors on these two compounds' absorption were investigated, such as buffer solution, duration of culture, and inhibitors of multidrug resistance-associated protein 2 (MRP(2)), breast cancer drug resistance protein (BCRP) and P-glycoprotein (P-gp). Methods: By using Caco-2 monolayer as an intestinal epithelial cell model, the transport process was studied from apical (AP) side to basolateral (BL) side or from BL to AP. The two compounds were determined by high-performance liquid chromatography coupled with diode-array-detector detection. Transport parameters and apparent permeability coeffients (P(app)) were calculated. Results: The P(app) values of scutellarin and scutellarein were different in two buffer solutions, respectively. In phosphate buffered saline, scutellarin had no absorption from AP to BL, while its P(app) value was 0.74×10(-6) to 1.58×10(-6) cm/s from BL to AP. The P(app) values of scutellarein were 4.33×10(-6) to 6.79×10(-6) cm/s and 1.32×10(-6) to 2.56×10(-6) cm/s from AP to BL and from BL to AP, respectively. The P(app) value gradually decreased with time. The absorption of scutellarein was better than that of scutellarin. The scutellarin absorption was improved by verapamil, MK-571 and reserpine. The scutellarein absorption was improved by verapamil whereas its excretion was improved by MK-571. Conclusion: Absorption of scutellarin is difficult in Caco-2 monolayer cells, which contributes to its low bioavailability. Scutellarein absorption is better than scutellarin absorption. Scutellarein transepithelial transport is passive diffusion. The inhibitor of P-gp can improve scutellarin and scutellarein transportation. The inhibitors of MRP(2) and BCRP can promote transportation of scutellarin. The inhibitor of MRP(2) can promote efflux of scutellarein. The multidrug resistance-associated protein may be the second reason for low bioavailability of scutellarin.
RESUMEN
Objective To evaluate the synergistic effect of DSA and MSCTA in interventional therapy for lung cancer. Methods Interventional therapy was performed in 46 patients with lung cancer. With real time helical thin slice CT scanning, MSCTA of tumor feeding artery was performed in 26 patients. Images obtained from enhanced MSCT scanning were processed at the console workstation. Spatial anatomical characteristics of tumor feeding artery were observed by using different rotations of view. DSA study and the interventional therapy were followed up in 26 patients with lung cancer. Results All tumor feeding arteries in 26 patients with lung cancer were observed by using VR, MIP and MPR, which could exactly display the origin, course and diameter of the vessels. DSA had a high consistency with MSCTA in displaying the tumor vascularity, tumor stain, and the origin of tumor-feeding artery in the patients who received MSCTA and the interventional therapy. The number of catheter used, the dosage of contrast medium, the sequence of subtraction, the fluoroscopic time and operation time in the group with use of CTA was less than that in the group without use of CTA, and the difference between two groups was statistically significant (P < 0.05), while no significant difference in detecting feeding artery existed between two groups (P > 0.05). Conclusion The anatomical characteristics of tumor-feeding artery in patients with lung cancer can be stereoscopically and clearly displayed on preoperative routine MSCTA, providing useful information and thus making the interventional procedure more safe and effective. Simultaneous use of DSA and MSCTA is reasonable and practicable, which has synergistic effect in interventional therapy for lung cancer.

Objective To explore the efficiency of arterial perfusion chemotherapy combined with embolization for the treatment of giant carcinoma of the kidney. Methods Arterial perfusion chemotherapy combined with embolization was performed through the renal artery in 21 cases of giant carcinoma of the kidney from April 1992 to April 2006. The chemotherapeutic agents contained carboplatin(300 mg), mitomycin(20 mg) and cyclophosphamide(800 mg). The embolization was conducted with anhydrous alcohol, sodium morrhuate, and lipiodol plus gelatin sponge. Results The arterial perfusion with embolization was successfully obtained in all 21 cases. Surgical resection was accomplished in 15 cases, 1 - 8 weeks after the embolization; revealing severely less or no blood supply to the tumor. Pathological findings showed marked necrosis of tumor cells with peripheral inflammatory infiltration, fibrous proliferation as well as capillary embolization. The survival rates at 1-, 2-, and 3-, year were 80%(12/15), 53.33%(8/15) and 40%(6/15) respectively. Conclusions Combination of perfusion chemotherapy and embolization through the renal artery for the treatment of giant carcinoma of the kidney offers promising clinical effects.
RESUMEN
Objectvive To evaluate the blood supply of pulmonary metastases using small volume of lipiodol through pulmonary arterial infusion. Methods 10 cases of lung metastasis were enroled including the primary tumors of liver cancer(n = 5), renal carcinoma(n = 3), chordoma(n = 1) and malignant neurofibroma (n = 1). Plain CT scan was performed to exclude calcification or ossification within metastasis and then pulmonary arterial DSA was undertaken to evaluate tumor vessels or staining. After pulmonary arteriovenous fistula or other anomalous circulation was excluded by lobar arterial DSA, small volume of lipiodol was infused under fluoroscopy (0.5 -1.5 ml for each lobar artery, total volume less than 3.0 ml). CT scan was immediately performed. Blood supply of the pulmonary metastases was assessed according to the accumulation of lipiodol on CT scans. Results No cases but one experienced cough, expectoration, suffocating or dyspnea. No complication of cerebral or visceral embolism occurred. Totally 27 nodules were studied including 6 nodules with cloudy lipiodol accumulation and 6 nodules with tiny granules of lipiodol accumulation. No enlarged tumor vessel or tumor stain was observed within all 27 nodules on pulmonary arterial DSA. Conclusions Pulmonary artery supplys only parts of pulmonary metastases, especially those sited at the peripheral region of the lung. Infusion of small volume of lipiodol through pulmonary artery is safe, and the increased density of lung field could return normal after several days.

Objective To analyze the treatment of transplant renal artery stenosis (TRAS) by percutaneous transluminal angioplasty (PTA) and stenting. Methods The average time duration from transplantation to the on set symptom of TRAS was 6.9 months (3 - 18 months) in 35 TRAS patients. BP and creatinine level were recorded before and after the procedure. PTA was performed through contralateral femoral or left brachial approach with ordinary balloon (5 F, length 20 ~ 30 mm) and / or small balloon catheters (2. 6 F, length 36 mm) in all patients, and stents were embedded in 11 of them. Results A total of 46 PTA were successfully performed (1 time, 20 cases; 2 times, 12 cases, and 3 times, 3 cases) via contralateral femoral approach (26) and left brachial approach (15). Stenosis were significantly decreased from 75% ~ 98% pre-PTA to 10% ~ 30% post-PTA.Systolic pressure decreased from 170 mmHg (150 ~ 210 mmHg) pre-PTA to 135 mmHg (100 - 190 mmHg) post-PTA and diastolic pressure decreased from 120 mmHg (90 - 145 mmHg) to 85 mmHg (80 - 125 mmHg) respectively. Restenosis rates were 39% after first PTA and 15% after the second time. All 46 times of PTA used 26 ordinary balloon catheters and 20 microballoon catheters. 8 self-expandable stents (Wallstent) and 3 balloon-dilatation stents (Palmaz) were released in 11 cases. There were healed case (n = 11) , melioration (n = 15), improvement (n = 7), and inefficiency (n = 2) after follow - up of 23 months (3 - 60 month). No complication occured except puncture site hematoma via the brachial artery approach in 1 case. Conclusions PTA is safe and effective in the treatment of TRAS and high rate of procedure success may be achieved with the help of brachial approach and micro-balloon catheter.Reasonable use of stents is beneficial in decreasing the restenosis.

RESUMEN
Objective:To optimize the injection protocol of contrast medium for contrast-enhanced MRA (CEMRA) of pulmonary artery and to evaluate the diagnostic value of CEMRA and pulmonary perfusion imaging (PPI) in an experimental model of acute pulmonary embolism. Methods:CEMRA and PPI were performed in 6 normal pigs with different doses of gadolinium contrast agent (5ml, 10ml, 15ml, 20ml and 25ml) at an injection rate of 3ml/s, and 3 pulmonary embolism models were injected with 20 ml contrast agent at 3 ml/s. DSA was also performed for comparison. Results:The signal intensities and the signal to noise ratios of the pulmonary arteries kept increasing with the dose increase of the contrast agent, but the best angio-pulmonary contrast dose was 10-15ml (0.25-0.375mmol/kg), while the optimal dose for PPI was 15-20ml (0.375-0.5mmol/kg). Although CEMRA demonstrated less obstructed pulmonary arteries than DSA (5/10 vs 8/10)did, it detected all obstructions when combined with PPI. The pulmonary infarction zones showed wedge-shaped perfusion defects on the PPI images, with the signal intensities lower than those of the normal areas (137.86±45.32 vs 330.14±46.52, P<0.001). Conclusion:It is suggested that the optimal dose of the contrast agent is 0.25mmol/kg to 0.375mmol/kg for CEMRA, and 0.375mmol/kg to 0.5mmol/kg for lung perfusion. CEMRA combined with PPI may be better than DSA in demonstrating pulmonary embolism.
