Objective To obtain the specific human scFv basic fibroblast growth factor(bFGF)using phage antibody library technology. Methods The library was panned with human recombinant bFGF for 4 rounds. The antigen binding activities of random clones were tested by ELISA in order to select specific antibodies, which were then examined by DNA sequence analysis. Results The positive clone selected from the 104 random clones was able to bind bFGF specifically, while not able to bind other growth factors,such as aFGF, VEGF(vascular endothelial growth factor). By competition ELISA assay we found one clone 44 could inhibit bFGF binding to FGFR1. Conclusion Seven specific human phage antibody against bFGF was obtained by phage display technique, one clone could inhibit bFGF binding to its high affinity receptor FGFR1.

Objective:To clarify the contribution of endogenous bFGF, bFGF mRNA and FGFR1 to the abnormal growth and phenotypic transformation of neoplastic tumors cells.Methods:The antisense oligonucleotide primers was used to evaluate the influence of endogenous bFGF on growth of human glioma malignant cell lines SWO-38 in vitro. MTT was used to examine the variety of cells growth treated with bFGF antisense oligonucleotide primers. The methods of ELISA, in situ hybridization, immuno-hischemistry and image analysis were used to detect the expression level of bFGF, bFGF mRNA and FGFR1. The colony formation of cells in soft agar was used to assess the cloning efficiency of the cells after exposed to bFGF antisense oligo-nucleotide primers.Results:The cells multiplication, expression of bFGF mRNA and FGFR1 was inhibited by bFGF antisense oligonucleotide primers,and the cells multiplication was dose-dependent. Treated with antisense oligo-nucleotide primers, the expression of FGFR1 and secretion of bFGF were distinctly reduced, and the inhibition efficiency of cells multiplication of WSO-38 was 48% and the inhibition efficiency of colonies of SWO-38 in soft agar was 35%. The inhibition of cells multiplication can be reversed completely by external bFGF, and the reverse efficiency was 8%.Conclusion:The synthesis of bFGF mRNA and expression of bFGF can be specifically inhibited by antisense oligonucleotide, but the inhibition can be cleared up with the addition of external bFGF. The study suggested that the bFGFantisense oligonucleotide could have good effect in inhibiting of tumor under special condition.

Objective: To determine the optimal manipulation parameters in Liu's back tuina therapy for remission-stage cough variant asthma (CVA) in kids. Methods: A 5-factor 3-level L18(37) orthogonal design was adopted. The experimental factors and levels were selected: A, the number of times of Rou-kneading Feishu (BL 13); B, the frequency of Rou-kneading Feishu (BL 13); C, the number of times of Tui-pushing in a '介'-like pattern; D, the frequency of Tui-pushing in a '介'-like pattern; E, the intensity of red color after Ca-scrubbing Feishu (BL 13) with salt. A1, A2 and A3 stood for 10 times, 20 times and 30 times, respectively; B1, B2 and B3 stood for 200 times/min, 240 times/min and 280 times/min, respectively; C1, C2 and C3 stood for 50 times, 75 times and 100 times, respectively; D1, D2 and D3 stood for 150 times/min, 175 times/min and 200 times/min, respectively; E1, E2 and E3 stood for pinkish, bright red and dark red, respectively. A total of 108 kids with CVA in remission stage were divided into 18 groups using the random number table method, with 6 cases in each group. Changes in the cough score and fractional exhaled nitric oxide (FENO) level were observed after 15-day treatment. Results: The cough score and FENO level changed significantly in every group after treatment (all P<0.01). By the effect in improving cough score, the factors were listed as D, B, A, C and E in descending order; the most optimal manipulation parameter combination was group 17 (A3B2C1D3E1); the second optimal parameter combinations were group 7 (A3B1C2D1E3), group 13 (A2B1C2D3E1) and group 14 (A2B2C3D1E2). Regarding the effect in down-regulating the level of FENO, the factors were listed as C, A, E, B and D in descending order; the most optimal manipulation parameter combination was group 13 (A2B1C2D3E1); the second optimal parameter combinations were group 18 (A3B3C2D1E2), group 16 (A3B1C3D2E3) and group 14 (A2B2C3D1E2).Conclusion: Two most effective manipulation parameter combinations were selected out of 18 different parameter combinations in Liu's back tuina therapy for remission-stage CVA in kids. Doctors can choose an appropriate manipulation based on the symptom features of the disease.

OBJECTIVETo analyze the relationship of quality of life and pain in patients receiving chemotherapy in the outpatient departments in a general hospital.

METHODA questionnaire-based survey was conducted to collect data on pain status, sleep disorder,vomiting,constipation as well as the social function status.

RESULTSAmong the 428 patient-times of survey, 12.2% of the patients had moderate to severe pain,of which 78.8% was consistent pain. The occurrence of pain was closely related to the metastasis of cancer (P = 0.000). The intensity and location of pain were independently correlated to the origin of cancer (P = 0.035, P = 0.000). Nearly a quarter of patients (24.5%) agreed that talking with his/her family was helpful to relieve pain, while 17.3% of patients had ambulatory restriction or changes in social function. The changes in social function were closely related with sleeping disorder, constipation, fatigue, and intensity of pain (all ,0.05). Furthermore, sleeping disorder was related to pain intensity (P=0.000), while constipation had no relationship with analgesic medicines (P = 0.798).

CONCLUSIONSA significantly large proportion of patients who are receiving chemotherapies in the outpatient departments of general hospital are suffering from moderate to severe pain. Their decreased social functions correlate with the cancer-related somatic symptoms.

OBJECTIVETo observe the effect of Bushen Huoxue Recipe (BHR) on inhibiting vascular calcification (VC) in chronic renal failure (CRF) rats by regulating BMP-2/Runx2/Osterix signal pathway, and to explore its possible mechanism.

METHODSThirty SD rats were randomly divided into the normal group, the model group, and the BHR group, 10 in each group. Rats in the model group and the BHR group were administered with 250 mg/kg adenine suspension by gastroagavage and fed with 1.8% high phosphorus forage, once per day in the first 4 weeks, and then gastric administration of adenine suspension was changed to once per two days in the following 5-8 weeks. Rats in the BHR group were administered with BHR at the daily dose of 55 g/kg by gastrogavage in the first 8 weeks, once per day. Equal volume of normal saline was given to rats in the normal group by gastrogavage for 8 weeks. Histological changes in renal tissue and aorta VC were observed by HE staining and alizarin red staining respectively. Levels of calcium (Ca), phosphorus (P), serum creatinine (Cr), blood urea nitrogen (BUN), and intact parathyroid hormone (iPTH) in serum were detected. Protein expression levels of bone morphogenetic protein (BMP-2), Runt related transcription factor (Runx2) , and Osterix were detected by Western blot.

RESULTSHE staining showed that compared with the normal group, disordered glomerular structure, tubular ectasia and dropsy, intracavitary inflammatory cell infiltration, dark brown crystal deposition in kidney tubules, renal interstitial fibrosis, and decreased number of renal blood vessels in the model group. Compared with the model group, normal glomerular numbers increased more, reduced degree of tubular ectasia, decreased number of inflammatory cells, and reduced adenine crystal deposition in the BHR group. Alizarin red staining showed that compared with the normal group, calcified nodes could be found in the model group, with extensive deposition of red particle in aorta. Compared with the model group, calcified nodes were reduced in the BHR group. Compared with normal group, serum levels of P, SCr, BUN, and iPTH significantly increased, serum Ca level significantly decreased, protein expressions of BMP-2, Runx2, Osterix also increased in the model group (P < 0.05, P < 0.01). Compared with the model group, serum levels of P, SCr, BUN, and iPTH levels significantly decreased, serum Ca level significantly increased, protein expressions of BMP-2, Runx2, Osterix also decreased in the BHD group (P < 0.05, P < 0.01).

CONCLUSIONBHD could improve renal function, Ca-P metabolism, and renal histological changes in CHF rats, down-regulate the expression level of BMP-2/Runx2/Osterix signal pathway in vascular calcification of CRF, which might be one of the mechanisms for inhibiting VC in CHF.

The effect of CO2 and the manner of CO2 offer on the growth rate and maximual cell density of ultro-high density culture of Chaetoceros mulleri in the photobioreactor were studied in the work. The amount of CO2 offered to the culture was controlled by the parameter of pH value in the culture. Furthermore the growth kinetics of Chaetoceros muller in the photobioreactor was studied. The results showed requirement of CO2 by the cells and the increase of pH in the culture were the key limiting factors to the growth, when a high cell concentration in the culture was reached. The offer of CO2 could improve the statute of CO2, could control the pH in the culture and increase the growth rate and maximum cell density. The results from the experiments of CO2 offer manner showed different efficiency to growth was resulted from differences of CO2 offer manner. The best way is mixing the CO2 and air before the CO2 was offered to the culture.
