To study the effect of physiological conditions on spidroins, we analyzed NTR1SR2CT module secondary structure, aggregation and silk-formation influenced by different salts (in different concentration intervals). According to the full-length Araneus ventricosus MiSp sequence, NTR1SR2CT module was constructed and expressed in Escherichia coli BL21 (DE3), and the recombinant proteins were purified by denaturation method mediated by 8 mol/L urea. Random coil and helix are the main secondary structures of NTR1SR2CT and could be induced into beta-sheet by drying natively and lyophilization, where methanol can be used as a promoter. Furthermore, potassium and phosphate cations can cause significant NTR1SR2CT protein aggregation and silk-formation. The results could be a basis for the determination of silk-formation mechanism, and also useful for industrialized generation of high performance spider silk-like fibers.

Objective To study the changes of umbilical blood lactate,pH, blood sugar(BS),bilirubin, electrolyte, osmotic pressure (OP) in the newboms with fetal distress.Methods Thirty-five newborns with fetal distress (distress group) and 40 healthy new-borns (control group) were studied. Distress group were divided into distress group Ⅰ and distress group Ⅱ respectively, based on without or with neonatal asphyxia. Concentration of umbilical blood lactate was determined with enzyme method, pH, BS,serum total bilirubin (BIL), serum electrolyte (Na+ ,K+ ,Ca2+ ) and OP were analyzed respectively. Results 1. The difference of incidence of newborn asphyxia between distress groups (29.03%) and control group (2.50%) was statistically significant. 2. Compared with the controls and distress group Ⅰ, the umbilical blood lactate concentration significantly increased in distress group Ⅱ (P 0.05).The incidence of hyperglycemia was significantly elevated in distress groups than that in the control group. 4. Lactate concentration in distress I and distress fl group showed negative correlation with pH. Conclusion The concentration of umbilical blood lactate can provide the proof for diagnosis and prognosis of fetal distress.

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.

Objective To investigate whether repeated low-frequency transcranial magnetic stimulation (rTMS) can affect the expression of Kca1.1,Nav1.6,NMDAR1 and/or GAD65 protein in the pyramid layer of the CA3 region of the hippocampus.Methods Fifty rats were randomly divided into an experimental group and a sham group.The former was administered low-frequency rTMS on 14 consecutive days ; the latter were given sham stimulation for 14 days.After the protocols were completed,each group was sub-divided into 6 h,24 h,1 week,3 week and 6 week sub-groups.The rats of each sub-group were sacrificed at the corresponding time points and the expression of KCa1.1,Nav1.6,NMDAR1 and GAD65 in the CA3 region of the hippocampus was examined using immunohistochemical techniques.Results Compared with the sham group,KCa1.1-positive neuron densities increased significantly in the period 6 h to 3 weeks after rTMS.GAD65-positive neuron densities were also elevated significantly from 6 h to 3 weeks.NaV1.6-and NMDAR1-positive neuron densities decreased transiently at 6 h after the completion of the rTMS protocol.Conclusions These results show that low-frequency rTMS can upregulate the expression of KCa1.1 and GAD65,and that the effect lasts for at least 3 weeks.It transiently downregulates the expression of NaV 1.6 and NMDAR1 in the hippocampal CA3 region,at least in rats.These changes may be one of its anti-epileptic mechanisms.

Results Compared with NP chemotherapy group, the tumor inhibiting rates, body weight, food intake, white blood cell number were increased and glutamate pyruvate transaminase, glutamic oxalacetic transaminase and urea nitrogen were decreased markedly in NP chemotherapy plus Scapharca Subcrenata Extraction groups. Conclusion Scapharca Subcrenata Extraction has a remarkable synergism and attenuation effects on NP chemotherapy.

Objective: To study the effect of arsenic trioxide (As 2O 3) on human pancreatic cancer cell proliferation and apoptosis (mainly early stage) in vitro . Methods: SW1990 cells line were treated with As 2O 3 at different concentration. Cell proliferation was evaluated by MTT and apoptosis by Annexin Ⅴ fluostaining, electron microscopy, flow cytometry and immunocytochemical staining of Bcl 2 and Bax. Results: As 2O 3 and cisplatin had the same cytotoxity on SW1990. The cytotoxic effect on tumor cell was produced by induction of apoptosis. Twelve hours after culture with 10 ?g/ml As 2O 3, much more SW1990 cells went into apoptosis than the control. The apoptosis rate reached 24% after 48 h with the similar concentration of As 2O 3. Immunohistochemical study revealed that the expression of Bcl 2 was decreased after treated with As 2O 3. Conclusion: As 2O 3 can depress the proliferation of SW1990 in vitro , mainly through the induction of apoptosis, and it is a potential agent for pancreatic cancer chemotherapy.
