ObjectiveTo investigate the serum soluble urokinase-type plasminogen activator (suPAR)in patients with multiple myeloma,its relationship with the 2-year survival rate and its clinical significance in predicting the disease prognosis.MethodsEnzyme-linked immunosorbent assay was applied to determine the levels of suPAR of 40 initial diagnosed patients with MM and 30 healthy persons as healthy control group.The patients were divided into three groups:effective (13 cases),remission (19 cases) and invalid (8 cases).ResultsUsually there was suPAR expression [(233.47±83.22) pg/ml] in serum of the healthy adults.There was no statistical difference of the suPAR expression in effective group or remission group before treated [(257.60±32.47) pg/ml,(331.00±99.80) pg/ml] compated with healthy group (t =2.04,t =1.83,P ＞ 0.05),and that in the invalid group,serum levels of suPAR [(562.20±291.0) pg/ml] was statistically significant with that of the effective group and that of the healthy control group (t =3.92,t =1.93,P ＜ 0.05).Through monitoring 17 patients,the suPAR of patients before treatment [(437.65±131.43) pg/ml] was statistically significant with that of healthy control group (P ＜0.01) and effective group after treatment [(298.76±108.59) pg/ml] (P ＜0.01).Serum suPAR of more than 2-year-survival patients [(333.02±85.37) pg/nl] during initial diagnosis was not statistically difference with that of the healthy control group (t =1.81,P ＞ 0.05).Serum suPAR of less than 2-year-survival patients [(646.01±103.97) pg/ml] was statistically different with that of healthy control group (t =3.84,P ＜0.01) and that of more than 2-year-survival patient group (t =3.50,P ＜0.01).ConclusionThe suPAR value was correlated to the stability of multiple myeloma,and can be used for disease prognosis and estimation of survival time.And the high expression of suPAR was related to the adverse prognosis.

In order to explore the possibility of Jerusalem artichoke stalk for bioenergy conversion, we analyzed the main composition of whole stalk, pitch, and core of the stalk. Meanwhile, these parts were pretreated with different NaOH concentrations at 121 degrees C. Afterwards, enzymatic hydrolysis was performed to evaluate the pretreatment efficiency. Jerusalem artichoke stalk was characterized by relatively high lignin content (32.0%) compared with traditional crop stalks. The total carbohydrate content was close to that of crop stalks, but with higher cellulose content (40.5%) and lower hemicellulose (19.6%) than those of traditional crop stalks. After pretreatment, the lignin content in the whole stalk, pitch, and core decreased by 13.1%-13.4%, 8.3%-13.5%, and 19.9%-27.2%, respectively, compared with the unpretreated substrates. The hemicellulose content in the whole stalk, pitch, and core decreased 87.8%-96.9%, 87.6%-95.0%, and 74.0%-90.2%, respectively. Correspondingly, the cellulose content in the pretreated whole stalk, pitch, and core increased by 56.5%-60.2%, 52.2%-55.4%, and 62.7%-73.2%, respectively. Moreover, increase of NaOH concentration for pretreatment could improve the enzymatic hydrolysis of the whole stalk and pitch by 2.3-2.6 folds and 10.3-18.5 folds, respectively. The hydrolysis of pretreated stalk core decreased significantly as 2.0 mol/L NaOH was employed, although the increased NaOH concentration can also improve its hydrolysis performance. Based on these results, hot-NaOH can be regarded as an option for Jerusalem artichoke stalk pretreatment. Increasing NaOH concentration was beneficial to hemicellulose and lignin removal, and consequently improved sugar conversion. However, the potential decrease of sugar conversion of the pretreated core by higher NaOH concentration suggested further optimization on the pretreatment conditions should be performed.

Objective To study the curative effect and side effect of thalidomide incorporation with NP in treatment of Ⅲ/Ⅳ lung cancer. Methods 36 lung cancer patients were randomly divided into three groups. The patients in experimental group were treated by NP plus thalidomide while without thalidomide in the control group. The difference between the first experimental group and second group is that the above used DDP followed with lobaplatin. The beginning dose of thalidomide was 100 mg/d, increase 50 mg/d every week till 400 mg/d, maintain for at least three months. Results The first experimental group had 4 partial relief cases (34.0 %), 5 improved cases(33 %), total efficacy rate was 34.4 %(4/15), clinical benefice rate 49 %(7/ 15), and the second group was 38 %(4/11), 27 %(3/11), 38 %(4/11), 55 %(6/11). All without significant difference. Conclusion It would be valuable to do clinical research further and widespread popularization study for evaluation of Thalidomide incorporation with NP in treatment of Ⅲ/Ⅳ lung cancer.

Aerenchyrna formation has been described in depth in a number of species at a histological level. But large gaps remain in our understanding of its regulation as a developmental process. It is attempted to analyse essential mineral elements like K, Mg, Cu, Zn, Ca and P in the cell wall of aerenchyma cells in petioles ofS. trifolia at five different developmental stages by CSEM-EDX technique. At early stage, K and Cl concentrations in cell wall were high up to 36% and 4.3% of dry weight, respectively. It supported the hypotheses that aerenchyma spaces are filled with liquid at early developmental stages of aerenchyma in S. trifolia petiole. Mg concentration was high at stage 2, up to 0.86% of dry weight. Zinc and Cu were detected only at rapid expansion stages, during which the concentrations were up to 1.5% and 2.5%, respectively. Calcium was detected in the cell wall only at mature stages, the concentration was high up to 1.3% of dry weight at stages 4 and 5. These results confirmed that the element concentration of aerenehyma cell wall undergoes dynamic changes during different developmental stages, and a low Ca with high Zn and Cu concentration are needed for cell expansion. Copper and Zn deposition in the cell wall showed a significant positive linear correlation, suggesting that these two elements share same or similar uptake and transport mechanism in plants.

OBJECTIVETo verify the clinical efficacy on chronic fatigue syndrome of qi deficiency syndrome treated with acupuncture at selective time and explore the effect mechanism.

METHODSEighty patients were randomized into a selective-time-acupuncture group and an acupuncture group, 40 cases in each one. Qihai (CV 6), Guanyuan (CV 4), Hegu (LI 4), Taichong (LR 3), Sanyinjiao (SP 6) and Zusanli (ST 36) were selected in the two groups. In the selective-time-acupuncture group, acupuncture was used at 9:00am to 11:00am. In the acupuncture group, acupuncture was used at any time except in the range from 9:00am to 11:00am. No any manipulation was applied after the arrival of needling sensation. The treatment was given once every day, 10 day treatment made one session and two sessions of treatment were required. The fatigue scale was adopted to evaluate the efficacy before and after treatment in the patients of the two groups. The ratios among CD3+, CD4+ and CD8+ T cells in the peripheral blood were detected before ad b a after treatment.

RESULTSIn the acupuncture group, the total score of fatigue and the score of physical fatigue were reduced after treatment as compared with those before treatment (all P<0.05). In the selective-time -acupuncture group, the total score of fatigue, the s core of physical fatigue and the score of mental fatigue after treatment were reduced obviously as compared with those hefore treatment (all P<0. 01). The improvements in the scores of the selective-time-acupuncture group were superior to the acupuncture group (all P<0. 05). The ratio of CD3+ and CD8+ T cells was increased obviously after treatment in the two groups (all P<0. 05) and the ratio of CD4+ and CD8+ T cells was reduced obviously in the selective-time-acupuncture group (P<0. 05), which was better than that in the acupuncture group (all P<0.05). The total effective rate was 95.0% (38/40) in the selective-time-acupuncture group, which was better than 80.0% (32/40) in the acupuncture group (P<0.05).

CONCLUSIONThe acupuncture therapy at selective time is effective in the treatment of chronic fatigue syndrome of qi deficiency syndrome, which is especially better at relieving mental fatigue. The effect of this therapy is achieved probably by improving the immune function via the regulation of the ratios among CD3+, CD4+ and CD8+ T cells.
