Objective To explore changes of serum fibroblast growth factor 2 (FGF2) levels after treatment with imatinib mesylate in patients with unresectable or metastatic gastrointestinal sromal tumor.Methods Serum FGF2 levels (with ELISA) were determined in 27 patients with unresectable or metastatic gastrointestinal stromal tumor both before and after treatment with imatinib mesylate.Results Before treatment with imatinib mesylate,of 27 cases of unresectable or metastatic gastrointestinal stromal tumor,17 cases (63.0 ％) were found positive for serum FGF2,after treatment with imatinib mesylate,9 cases (33.3 ％) were found positive for serum FGF2 (P ＜ 0.05).Using imatinib mesylate for 3 months,complete remission rate was 0,partial remission rate was 51.9 ％ (14/27),stable disease rate was 48.1％ (13/27) and progressive rate was 0.Conclusion Patients with unresectable or metastatic gastrointestinal stromal tumor have elevated serum FGF2 levels.Imatinib mesylate treatment can reduce serum FGF2 levels in patients with unresectable or metastatic gastrointestinal stromal tumor.

ObjectivesTo explore the serum insulin-like growth factor-1 (IGF-1)levels in the patients with unresectable or metastatic gastrointestinal stromal tumors before and after imatinib treatment and to discuss its clinical significance.MethodsThe serum samples of27 patients with unresectable or metastatic gastrointestinal stromal tumors were collected before imatinib treatment(before treatment group) and three months after imatinib treatment(after treatment group).The other serum samples were collected from 20 healthy volunteers who were accepting health examination (control group). The serum IGF-1 levels of the samples were determined by enzyme-linked immunosorbent assay (ELISA).ResultsThe mean serum IGF-1 levels were significantly higher in before treatment group than in control controls[(463.61±120.98)ng/ml vs.(115.75±39.27) ng/ml, t=12.355,P=0.000)]. Three months after imatinib treatment,the mean serum IGF-1 levels were significantly lower in after treatment group than in before treatment group [(244.64±100.11)ng/ml vs.(463.61±120.98) ng/ml, t=7.582,P=0.000].ConclusionsSerum IGF-1 levels may help to judge therapeutic effect,progression,recurrence or metastasis of the gastrointestinal stromal tumor.

Objective To investigate the expression of MMP-2 and c-erbB-2 and evaluate the correlation of clinical pathological parameters in non-small cell lung cancer. Methods Forty-five paraffin-embedded specimens of radical postoperative non-small cell lung cancer was detective for MMP-2 and c-erbB-2 using immunohistochemical method. Results The positive rates of MMP-2 and c-erbB-2 are 57.8 %, 75.6 %, there is a significance between the expression of MMP-2 and lymph node metastases(P =0.006), the expression of c-erbB-2 is related to clinical stage and lymph node metastases (P =0.015, P =0.032), The expression of MMP-2 and c-erbB-2 are related to 5-year survival rate (P =0.002, P =0.003). Conclusion The expression of MMP-2 and c-erbB-2 is significantly related to some clinical parameters and 5-year survival rate.

Objective To compare the efficacy and toxicity of melphalan + prednisone + thalidomide regimen (MPT) and melphalan + prednisone regimen (MP) in the treatment of multiple myeloma (MM).was given 100-200 mg/d everyday. 21 cases in MP group, the dose of melphalan and prednisone were the same as that in MPT group. The efficacy was evaluated after 6 cycles of treatment. Results The overall response rate (ORR) of MPT group and MP group were 65.4 % and 42.9 %, respectively (P＞O.05). The median response time in MPT group versus MP group was 2 months versus 3 months. Compared with the MP group. the increase of hemoglobin and albumin concentration in the MPT group is significantly higher (P＜ 0.05).The incidence of adverse effects of MPT group was higher than that of MP group (P ＜0.05), but the percentage of grade 3 and grade 4 toxicity was no different. The median PFS in MPT group was 11 months, 2-year PFS was 66.18 %. Conclusion Compared with MP, MPT could achieve higher response rate, improve the life quality and prolong the survival time of MM patients with better tolerance.

Objective To discuss hemorheologic changes and hepatic function in patients with chronic hepatitis B(CHB)and its correlation with HBV genotype.Methods Relative index of hemorheologic changes,ALT,HBV-DNA and HBV genotype were examined in 96 CHB patients and 24 healthy control people.The results underwent correlation analysis.Results Low-shear blood viscosity and RBC aggregation index were significantly higher in CHB patients than those in the healthy control people(P＜0.05).Low-shear blood viscosity and RBC aggregation index were significantly higher in CHB patients with abnormal ALT than those CHB patients with normal ALT and the healthy control people(P＜0.05).No statistical difference was seen when CHB patients with normal ALT were compared with the healthy control people and patients with positive HBV-DNA were compared with patients with nesative HBV-DNA(P＞0.05).No statistical difference was seen in hemorheologic changes in CHB patients with different genotype(P＞0.05).Conclusions Microcirculation disorder of CHB patients is correlated with damage degree of hepatic function.Hemorheologic changes are not correlated with HBV-DNA and HBV genotype,so it can be a relatively independent index for clinical evaluation of disease.

Objective To discuss and analyze the serum epidemiological characteristics of hepatitis B among people in Jinan in order to formulate applicable community nursing measures to control hepatitis B. Methods The serum marker of hepatitis B was tested by enzyme-linked immunosorbent assay in 26756 serum samples by strict operation according to the kit introduction. The data were analyzed by SPSS 13.0 software. Results The positive rate of HBsAg was 7.39%, among which the positive rate of male was 8.81% and female 5.54%, which was lower than that of the male (P<0.01). The positive rate of people lower than 20 years old was lower than those of above 20 years old. The positive rate of male from 21 to 30 years old was lower than those from 41 to 50 years old (P<0.05). No difference was seen between people with different professionals. Conclusions Vaccine inoculation of hepatitis B for susceptible population combined with community health education about hepatitis B related knowledge and comprehensive nursing intervention proved to be the pivotal measures for the control and prevention of hepatitis B.

Saussurea medusa is a rare traditional Chinese medicinal herb. Besides anti-inflammatory and analgesic activities, it has effects of disinhibiting cold, dispelling dampness and promoting blood circulation. Flavonoids are the main medicinal compounds in S. medusa. Contents of flavonoids and expression of flavonoids biosynthesis related genes in white and red (induced by low temperature, high sucrose and high light) callus were analyzed. The results showed that the total flavone in red line was 3.60 times higher compared to white line. The accumulation of rutin in red line (0.25% of dry weight) was 2.40 times higher compared to white line. Anthocyanins were abundant in red line, with the contents of cyanidin 3-O-glucosidechloride and cyanidin 3-O-succinyl glycoside 0.12% and 0.19% of dry weight respectively. CHS, F3'H, FNS, FLS, DFR and ANS genes were highly expressed in red line compared to white line. Expression of three transcription factors (MYB, bHLH and WD40) in red line was significantly higher than that in white line, especially the expression of MYB (19.70 times higher compared to white line). These results indicated that high expression levels of transcription factors induced high expression of structural genes in red line, thereby enhancing the flavonoids biosynthesis. The expression of bHLH and WD40 was similar, whereas it was significantly different from that of MYB, indicating that bHLH and WD40 could form a binary complex to regulate expression of structural genes and flavonoids biosynthesis.
