The human GM CSF cDNAandEGFP cDNA were linked together with IRES and then inserted into the expression vector pCI Egr 1, which was constructed by substituting CMV promoter in pCIneo with the Egr 1 promoter(Egr EG).The vector was transfered into human bone marrow stromal cell line HFCL by Lipofectin TM . The results indicated that the activity of EGFP in transfected cells increased at 18h after exposure to 2.5 Gy. The amounts of secreted GM CSF and CFU GM in serum free supernatants of Egr EG was significantly higher than the control group. EGFP and GM CSF cDNA were successfully integrated and expressed in the cells, which were confirmed by FACS and RT PCR analysis respectively. These in vitro data provide an experimental basis for the in vivo use of gene therapy of GM CSF gene regulated by Egr 1 promoter to protect hematopoiesis from total body irradiation.

Objective To explore the findings and clinical value of bedside ultrasonography in superior vena cava(SVC) syndrome in children after cardiac operations for congenital heart disease. Methods Bedside ultrasonography was performed on 6 children suspected of SVC syndrome after 5-38 hours[(22?11) hours] postoperatively,to view the structure and blood flow of SVC and its main branches. All the patients were reoperated as soon as diagnosed. Results Five children got severe SVC obstruction, marked with stenosis, turbulent, continuous and high velocity in SVC. Color Doppler flow imaging presented almost absence of flow due to nearly complete occlusion of the innominate vein in 1 child. Ultrasonographic diagnosis was confirmed by the reoperative findings. All the patients were cured by reoperation and discharged with normal ultrasonographic results. Conclusions Bedside ultrasonography can provide early and accurate diagnosis in children with SVC syndrome after cardiac operation.

Objective To examine outcomes of superficial vein stripping for vein varicosis caused by combination of superficial and deep venous reflux and the effect on deep vein reflux. Methods From January 2004 to December 2006, twenty patients (22 lower extremities) with combined superficial and deep venous reflux were enrolled for evaluation, patients with superficial venous reflux alone worked as controls.All patients underwent superficial vein stripping and followed up for 2 years. Venous clinic severity score (VCSS) and color duplex ultrasound test were used to evaluate the change of clinic symptoms and valve reflux of deep veins. Results Preoperative VCSS of superficial and deep vein reflux group and superficial vein reflux group was 7.1 ± 2. 9 and 6. 6 ± 2. 0 respectively (P = 0. 44). At two years after operation the VCSS was 2. 3 ± 1.2 and 1.8 ± 0. 8 respectively without significant statistic differences, whereas comparing postoperative VCSS with individual preoperative parameters there was a significant decrease (P <0. 01). In combined superficial and deep vein group, deep venous reflux reduced in 7 limbs, progressed in 4 limbs, no change in 12 limbs. While in superficial reflux alone group, deep venous reflux occurred in 4 limbs.Conclusions Superficial vein stripping effectively improves symptoms of great saphenous vein varicosis of lower extremity caused by combination of superficial and deep vein reflux without a significant effect on the stares of deep vein reflux.

Objective To investigate the influence of heme oxygenase-1 (HO-1) on rat renal tubular epithelial cell apoptosis induced by albumin and the possible mechanism. Methods The renal tubular epithelial cells (NRK-52E) were cultured in DMEM/F12 1:1 medium as normal control group; NRK-52E cells were cultured with 30 g/L fat-free bovine serum albumin (BSA) as the BSA control group; NRK-52E cells were cultured with CoPP (Cobalt pretoporphyrin Ⅸ) 5 μ mol/L for 24 hours as the treatment group. MTT assay was used to observe the effects of CoPP on growth inhibition induced by BSA in NRK-52E cells. The effect of CoPP was observed in BSAinduced apoptosis with the fluorescence microscope dyed by AnnexinV-FITC PI. The levels of HO-1, and expression of Bcl-2 and Bax mRNA were detected by reverse transcript polymerase chain reaction (RT-PCR). Results Compared with normal control group, BSA inhibited the growth of NRK-52E cells (P<0.05) and increased cell apoptosis rate (P<0.05). The CoPP pretreatment partially inhibited the BSA-induced apoptosis(P<0.05). Compared with normal control group, HO-1 mRNA expression increased (0.44±0.06 vs 0.39±0.05, P<0.05) in BSA control group. Compared with the BSA control group, the expression of HO-1 mRNA significantly increased after CoPP pretreatment(0.50±0.06 vs 0.44±0.06, P<0.05 ). Meanwhile, BSA increased the expression of Bax mRNA (0.87±0.04 vs 0.67±0.03, P<0.05)and reduced the expression of Bcl-2 mRNA (0.25± 0.04 vs 0.42±0.02, P<0.05 ). CoPP could inhibit the effect of BSA (Bax mRNA: 0.75±0.07, Bcl-2 mRNA: 0.36±0.03, P<0.05, respectively). Conclusions BSA can increase the apoptosis rate significantly and regulate the expression of apoptosis associated proteins in mRNA level directly. CoPP inhibits these changes, which provides evidence to support the essential role of HO-1 in cytoprotective function .

Chinese Traditional and Herbal Drugs 2013;44(14):1962-1966
Objective: To study the antidiabetic constituents of Tibetan Medicine "Meiduoluomi". Methods: Erigeron multiradiatus (EM) is one of the crude materials. The chemical constituents in EM were extracted and isolated by extraction and macroporous resin column. The inhibitory activities of the extracts against aldose reductase (AR) were evaluated in vitro to make sure the active fragments. Diabetic rats induced by streptozotocin were randomly divided into four groups: model (distilled water), positive control (epalrestat 10 mg/kg), EM II low-and high-dosage (200, 400 mg/kg) groups. The rats were ig administered once daily for 11 weeks. The rat normal sign, body weight, urine glucose, blood glucose, hemodynamics, and cardiac function parameters were determined. Results: Both EM I and EM II showed the inhibitory activities against AR with IC50 values of 0.64 and 0.12 mg/mL, respectively. Compared with diabetic group, body weight, heart rate, left ventricular end diastolic pressure average (LEVDP) and the left ventricular maximum rate of pressure development (+dp/dtmax) in EM II group were significantly improved, while blood glucose was decreased (P < 0.05, 0.01, 0.001). Conclusion: EM II demonstrates the obvious inhibitory activity on AR, and could improve the hemodynamics and protect heart function, which may be the antidiabetic active constituents of "Meiduoluomi".
9. Authentication of Angelica sinensis and adulterants by analysis of plastid trnL-F and rpoC1 sequences
Chinese Pharmaceutical Journal 2015;50(10):840-845
OBJECTIVE: To establish a new method for identification of Angelica sinensis from its adulterants by analyzing trnL-F and rpoC1 sequences. METHODS: The plastid trnL-F and rpoC1 of 25 samples of A. sinensis and its adulterants were amplified, sequenced, and analyzed. The K-2-P distances of A. sinensis and its adulterants were calculated, and the phylogenetic trees were constructed. RESULTS: The trnL-F sequence showed significantly larger length variation range, numbers of variable sites and informative sites, and evolutionary distance than rpoC1 sequence. There were significant differences between A. sinensis and the adulterants based on the trnL-F sequences. One SNP site and one repeated base A region could be used as specific authenticable sites. The distance of A. sinensis and its adulterants ranged from 0.002-0.231 as shown by trnL-F sequences. Phylogeny tree reconstruction using MP analysis based on trnL-F sequences could effectively distinguish A. sinensis from adulterants. However, analysis of the rpoC1 sequences could not identify A. sinensis and its adulterants. CONCLUSION: The rpoC1 sequence has poor capability for identification of A. sinensis and its adulterants. The trnL-F sequence could be used as an efficient molecular marker for authenticating A. sinensis from its adulterants.
