OBJECTIVETo observe the clinical efficacy of Safflower Injection (Al) in treating and preventing the vascular crisis after free flap transplantation.

METHODSSixty patients undergoing free flap transplantation were randomly assigned to the treatment group and control group according to the visiting sequence, thirty in each. Free flap transplantation was performed on all patients, and medication was given 0. 5 h before flap vascular anastomosis, 1-7 days after surgery. Twenty mL Al was intravenously dripped to patients in the treatment group after adding in 250 mL 5% glucose injection, while Dextran-40 was intravenously dripped to patients in the control group. The medication was conducted once per day. The hemorheology and four indices of blood coagulation [prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (APTT), fibrinogen (FIB)] were compared between the two groups before operation (TO), during operation (T1), 24 h after operation (T2), three days after operation (T3), and seven days after operation (T4). Meanwhile, flaps were observed and adverse reaction recorded. The clinical efficacy and safety were compared.

RESULTSBetter result was obtained in the treatment group when compared their clinical efficacy (86. 67% vs 60. 00%, P<0.05). The whole blood high and low viscosity, plasma viscosity, red blood cell (RBC) volume, RBC aggregation index all decreased, and RBC deformed index increased in the two groups at T4, showing statistical difference when compared with those at T3 (P<0.05, P<0.01). There was no statistical significance in the four indices of blood coagulation when compared with any time point in the same group (P>0.05). There was no statistical significance in hemorheology and the four indices of blood coagulation between the two groups at the same time point (P>0.05). The adverse reaction rate in the treatment group was lower than that in the control group, showing statistical difference (13.33% vs 30.00%, P<0.05).

CONCLUSIONSAI could effectively prevent and treat the vascular crisis after free flap transplantation. It had less adverse reaction and good safety. It was better than Dextran-40. It was a safe and effective drug to prevent the vascular crisis.

OBJECTIVE: To explore the correlations between symptom-based principal factors of rheumatoid arthritis (RA) and the effect of traditional Chinese medicine or Western medicine on RA after factor analysis of RA symptoms. METHODS: Four hundred and thirteen RA patients from 9 clinical centers were included in the clinical trial. They were randomly divided into Western medicine (WM) treated group with 204 cases and traditional Chinese medicine (CM) treated group with 209 cases. A complete physical examination and 18 common clinical manifestations were recorded before the randomization and after the treatment. The WM therapy included voltaren extended action tablet, methotrexate and sulfasalazine. The CM therapy included glucosidorum Tripterygll totorum tablet and Yishen Juanbi Tablet. The American College of Rheumatology 20 (ACR20) was used for efficacy evaluation. All data were analyzed on SAS 8.2 statistical package. Eighteen symptoms in the RA patients were analyzed by factor analysis and the relationships between the factors and effects were analyzed with Chi-Square test. RESULTS: Four principal factors were obtained from the analysis results of the 18 symptoms. The factors could represent the symptoms related to joints, cold-syndrome, deficiency syndrome and heat-syndrome in traditional Chinese medicine (TCM), respectively. The effect of WM therapy was better than CM therapy. After 12 weeks of treatment, the effect of CM on patients without deficiency-syndrome was better than the patients with deficiency-syndrome. After 24 weeks of treatment, WM therapy showed better effect on patients with cold syndrome than patients without cold syndrome. CONCLUSION: The results based on the factor analysis of RA symptoms are similar to the results of syndrome differentiation of TCM, and the factor-related different categories of symptoms are associated with the curative effect, thus further research on the symptoms is necessary.

HER2, a member of epidermal growth factor receptor family proteins, is overexpressed in about 30% of human breast cancer. Increased levels of HER2 are associated with poor patient prognosis and enhanced metastasis. RNA interference (RNAi) is developed recently as a new technique which can inhibit gene expression specifically in mammalian cells. On the basis of previous study,in which two target sequences with favorable RNAi effect on HER2 were identified, a series of dual promoter siRNA-expressing vectors containing two opposing U6 and H1 promoters were constructed. After transfection of HER2-overexpressing SKBR3 breast cancer cells with the siRNA-expressing vectors, downregulation of HER2 was identified quantitatively. Subsequently, the siRNA-expressing cassettes were subcloned into lentiviral vectors by LR recombination reaction and lentivirus was prepared successfully. The results from infection of SKBR3 cells with siRNA-expressing lentivirus demonstrated that lentiviral-mediated RNAi could downregulate HER2 expression efficiently through fluorescent quantitative PCR (FQ-PCR), western blot, and FACS analysis. Furthermore, cell growth was inhibited in cell proliferation assay after treatment with siRNA lentivirus.A new tool for clarifying the function of HER2 in cancer metastasis and developing the gene therapy drug was offered.

Fhx/P25 in silkworm, Bombyx mori, one of the main components of silk fibroin, is presumed in previous reports to be expressed exclusively in the posterior silk gland (PSG) of the animal with strict territorial and developmental specificities. On the basis of a large-scale analysis ofthe silkworm EST data, it was found that Fhx/P25 gene is transcribed not only in the posterior silk gland, but in the ovary and in other tissues of the larvae at day 3 of the fifth-instar as well and that this gene has distinct transcription start sites (TSSs) in the posterior silk gland and the ovary. The TSS in the ovary is located about 115 bp upstream sequence of that in the posterior silk gland. Subsequent RT-PCR, FQ-PCR and sequencing have verified the validity of this presumption. In addition, alternative splicing is predicted in pre-mRNA of Fhx/P25 gene and confirmed by RT-PCR. In conclusion, Fhx/P25 gene is not a gene with strictly tissue-specific transcription.Complicated regulation mechanisms may exist for its transcription and expression and it may have other functions to perform.

Objective To investigate the inhibitory effect of octreotide on transforming growth factor-alpha (TGF-?)-induced cell proliferation of human hepatocellular carcinoma cells and its possible mechanism. Methods The effect of octreotide on TGF-?-induced cell proliferation of the liver cancer cells (LCC) was evaluated by immunohistochemistry method. The effect of octreotide on TGF-? secretion and epidermal growth factor receptor(EGFR) expression in the cells was determined by reverse-transcriptase polymerase chain reaction(RT-PCR). The effect of octreotide on extracellular signal-regulated protein kinase (ERK) expression in the cells was measured by Western-blot and immunohistochemistry method. Results The TGF-?-induced expressions of proliferating cell nuclear antigen (PCNA) in nucleus were obviously increased by TGF-?. TGF-?mRNA index of hepatocellular carcinoma cells was decreased by octreotide. Octreotide inhibited significantly the expressions of EGFR mRNA induced by TGF-?. Octreotide inhibited significantly the expressions of ERK protein induced by TGF-?. There was intense staining in the nucleus of the cells by TGF-? and weak staining in the nucleus of the cells treated simultaneously by octreotide and TGF-?.Conclusions Octreotide can inhibit the secretion of TGF-?, the expression of EGFR, and the signal transduction of EGFR of LCC, and consequently exerts an inhibitory effect on TGF-?-induced hepatocellular carcinoma cells proliferation.
