Objective To explore the relationships of quality of life ( QOL ) and functional status in patients with malignant bone tumors after operation. Methods European organization for research and treatment of cancer quality of life questionnaire C30 (EORTC-QLQ-C30), social support revalued scale (SSRS) and Karnofsky performance scale (KPS) were used to investigate the levels of QOL, social support and functional status. The correlations between them were explored. Results The overall score by QOL was (58.33 ± 18.94). The score by KPS was positively related to somatic function, role function, social function, and general health status (P<0.01), but negatively related to tiredness, pains, insomnia and financial burden (P<0.01). Conclusions The QOL in patients with malignant bone tumors after operation is at a lower level and the function is at a medium level. Nurses should assess the function and make out interventional measures for them so as to improve their QOL.

To study the pharmacokinetics characteristic of loganin, ferulic acid and stilbene glucoside in rat plasma after oral administration of Bushen Tongluo formula. The plasma samples were treated by using liquid-liquid extraction technique, the concentrations were determined by HPLC-UV. Johnson spherigel C18 column (4.6 mm x 250 mm, 5 μm) was adopted and eluted with the of mobile phase of methanol-water containing 0.01% glacial acetic acid in a gradient mode, with the flow rate at 1.0 mL x min(-1), column temperature at 30 degrees C and injection volume of 10 μL. According to the findings, loganin was determined at 235 nm, ferulic acid and stilbene glucoside were determined at 320 nm, with the sample size of 10 μL. The pharmacokinetic parameters of loganin, ferulic acid and stilbene glucoside were calculated by DAS 2. 0 software as follows: C(max) was (0.369 ± 0.042), (0.387 ± 0.071), (0.233 ± 0.044) mg x L(-1); t(max) was (0.226 ± 0.022), (0.282 ± 0.031), (0.233 ± 0.044) h; t(½β) was (6.89 ± 0.20), (10.73 ± 0.11), (6.93 ± 0.09) h; AUC(0-∞) was (1.91 ± 0.36), (3.22 ± 0.52), (1.52 ± 0.33) mg x h x L(-1); AUCO(0-t) was (1.62 ± 0.33), (2.58 ± 0.43), (1.30 ± 0.30) mg x h x L(-1); CL was (20.2 ± 4.0), (1.39 ± 0.23), (31.7 ± 6.9) L x h(-1) x kg(-1), respectively. The results showed that after the oral administration with Bushen Tongluo formula, loganin, ferulic acid and stilbene glucoside showed concentration-time curves in conformity with the two compartment model, with a rapid absorption, loganin and stilbene glucoside was excreted at a moderate speed, and ferulic acid was excreted slowly (but with the highest bioavailability).

Objective To study the effects of Cad-Ⅱgene on osteogenic differentiation of human mesenchymal stem cells in vitro. Methods The human marrow mesenchymal stem cells (hBMSCs) were isolated and cultured in vitro before they were divided into 2 groups. In the transfeetion group, the hBMSCs were transfeeted with Cad- Ⅱgene;in the simple osteogenic inducement group, they were cultured in the condition medium. Then the expressions of Cad- Ⅱ protein were determined and the alkaline phosphatase (ALP) activities and the expressions of ostcocalein were measured at 3, 7, 14 and 21 days for comparison between the 2 groups. Results The ALP activity and positive expression of osteoealcin were regulated significantly higher in the transfeetion group than in the simple osteogenic inducement group at different times (P <0.05). The mineralized nodes began to appear at 14 days in the 2 groups and increased with time. Conclusion Cad-Ⅱgene transfeetion can promote differentiation of hBMSCs into the osteoblasts.

The fermentative H2-producing strain Clostridium sp. H-61 was isolated from anaerobic sludge,was used as an original strain which was induced by NTG and UV for increasing and the hydrogen production ability. One of the highest efficient H2-producing mutants was named as HCM-23 with its stable hydrogen production ability. which was measured in the batch culture experiments. With the condition of 10 g/L glucose,its cumulative hydrogen yield and hydrogen production rate was 3024 mL/L and 33.19 mmol H2/g DW?h,69.89% and 68.14% higher than that of the original strain,respectively. The terminal liquid product compositions showed that the mutant HCM-23 fermentation was ethanol type,while the original strain H-61 fermentation was butyric acid type. Varieties of parameters of hydrogen production fermentation studied,including time,carbon source,nitrogen source,glucose concentration,glucose utilization,initial pH and incubation temperature had been studied,indicated the optimum condition of hydrogen production for the mutantHCM-23 as initial pH 6.5,temperature 36 ℃,and the favorite substrate was sucrose. The hydrogen production characters of the mutant and the original strain were different,such as,the growth lag phase and the utilization of inorganic nitrogen source,etc. This work shows a good application potential of NTG-UV combined mutation in the biohydrogen production. And the hydrogen production mechanism and metabolic pathway should be explored furthermore.

Objective To investigate the relationship between recurrent spontaneous abortion (RSA) and the level of interferon-γ(IFN-γ) and interleukin-4 (IL-4) in peripheral blood and gingival crevicular fluid of patients with chronic periodontitis.Methods Fifty pregnant women with recurrent spontaneous abortion(gestational age: 5-28 weeks) and 40pregnant women (gestational age: 39-41 weeks)were included and their periodontal status was examined.The level of IFN-γ and IL-4 in gingival crevicular fluid and peripheral blood was detected by enzyme-linked immunosorbent assay.Results Nine RSA women and 5 in control group had periodontitis.The prevalence of periodontitis in RSA group was 18％ (9/50) and 13％ (5/40) in the control group(P ＜0.05).The probing depth,attachment loss and bleeding index in RSA group were higher than those in the control group(P ＜0.05).The level of IFN-γwas (52.98 ± 17.56) ng/L in gingival crevicular fluid of RSA group and (25.25 ± 7.93) ng/L in control group(P ＜ 0.01).The level of IL-4 was (15.43 ± 1.77) ng/L in gingival crevicular fluid of RSA group and (19.62 ± 4.04) ng/L in control group (P ＜0.01).The content of IFN-γwas (27.79 ± 3.59) ng/L in peripheral blood of RSA group and (18.39 ±2.65) ng/L in control group(P ＜0.05).The content of IL-4 was (15.88 ± 0.95) ng/L in peripheral blood of RSA group and (22.98 ± 4.30) ng/L in control group (P ＜ 0.001).The content of cytokines in gingival crevicular fluid and peripheral blood in the same group was positively related (r ＞ 0.8,P ＜ 0.001).Conclusions Pregnant women of RSA have a higher chance of getting periodontitis.The change in the level of cytokines in periodontal tissue could result in excursion of maternal intrauterine immune environment to T-helper 1 (Th1).Periodontitis was related to RSA.

OBJECTIVETo study emetic and anti-emetic effects of Rhizoma pinelliae in minks.

METHODThe emetic effect of raw pinellia 2 g kg(-1) (i.g.) was investigated. Three preparations of Rhizoma pinelliae (processed with ginger) were made by ethanol extraction, water extraction and water decoction respectively and their effects on emesis model induced by cisplatin (7.5 mg kg(-1), i.p.) or apomorphine (1.6 mg kg(-1), s.c.) were then studied; the effect of the decoction of ginger-processed Rhizoma pinelliae on rotation-induced emesis model in minks was also observed.

RESULTThe emesis was induced by raw pinellia in minks (P < 0.01); ginger-processed Rhizoma pinelliae, metoclopramide and ondansetron significantly inhibit the emesis induced by cisplatin and apomorphine (P < 0.05).

CONCLUSIONGinger-processed Rhizoma pinelliae exhibits a anti-emetic effect in minks, which may be mediated by inhibiting the function of the vomiting center in central nervous system.

OBJECTIVETo observe whether Xuefu Zhuyu Decoction (XZD) could induce the differentiation of mesenchymal stem cells (MSCs) into cardiac myoid cells, thus seeking for safe and effective inducers.

METHODSThe serum pharmacological method was used to induce. XZD containing serum was prepared. MSCs were isolated and cultured. The serum cytotoxicity was detected by MTT. The third generation of favorably grown cells was selected in this experiment. Cells were divided into three groups, i.e., the vehicle control group, the XZD containing serum induced group, and the 5-azacytidine induced group. Expressions of Desmin and alpha-actin were detected by immunocytochemical staining method.

RESULTSBefore induction protein expressions of Desmin and alpha-actin were negative, and few was weakly positive. There was no statistical difference in the weak positive expression rate among the 3 groups (P > 0.05). After induction protein expressions of Desmin and alpha-actin were negative, and few was weakly positive in the vehicle control group. Protein expressions of Desmin and alpha-actin were positive in the XZC containing serum induced group and the 5-azacytidine induced group. There was statistical difference in the positive expression rate when compared with the vehicle control group (P > 0.05).

CONCLUSIONSXZD played a role in in vitro inducing differentiation MSCs to cardiac myoid cells. It might participate in expressions of Desmin and alpha-actin.
