Objective To investigate the effects of ZGDHu-1 on T lymphocytes activation in vitro to elucidate its immunosuppressive effects. Methods Lymphocytes isolated from healthy persons were stim-ulated with phytohanmagglutinin(PHA) and different experimental groups were set by cocultured for 24 h, 48 h with ZGDHu-1 or with ZGDHu-1 and Cyclosporin A(CSA). To assess the proliferation and apoptosis of T lymphocytes, we detected CD3~+ CD69~+ , CD3~+ CD25~+ , CD4~+ CD25~+ , CD8~+ CD25~+ and CD3~+ Fas~+, CD4~+ Fas~+ , CD8~+ Fas~+ with flow cytometry. The early apoptosis rate of lymphocytes was analyzed with flow cytometry. Culture supernatant IL-2 and TGF-β1 were detected with ELISA. Results ZGDHu-1 decreased PHA activative CD3~+ CD69~+, CD3~+ CD25~+, CD4~+ CD25~+ and CD3~+ Fas~+, CD4~+ Fas~+, Annexin V~+/ PI~- and inhibited IL-2 secretion and promoted TGF-β1 secretion respectively. ZGDHu-1 has synergistic effect with CSA to be more obvious. Conclusion ZGDHu-1 can inhibit T lymphocytes activation and de-creased apeptosis of T lymphocytes. ZGDHu-1 has synergistic effect with CSA to be obvious.

Human errors are errors found in planning or implementation, and those found in medical practice are often major causes of mishaps.To name a few, wrong-site surgery, medication error, wrong treatment, and inadvertent equipment operation.Errors of this category can be prevented by learning from experiences and achievement worldwide.Preventive measures include those taken in human aspect and system aspect, reinforced education and training, process optimization, and hardware redesign.These measures can be aided by multiple safety steps in risky technical operations, in an effort to break the accident chain.For example, pre-operative surgical site marking, multi-department co-operated patient identification, bar-coded medication delivery, read-back during verbal communication, and observation of clinical pathway.Continuous quality improvement may be achieved when both the management and staff see medical errors in the correct sense, and frontline staff are willing to report their errors.

Objective To observe the effect of electroacupuncture(EA) on Calbindin D28K(CB) expression and apoptosis in hippocampus in hyperlipemia rats with concomitant cerebral ischemia(CI).Methods Forty male SD rats were rando-mized into control,hyperlipemia+CI(model),acupuncture Ⅰ,and acupuncture Ⅱ groups,with 10 cases in each.Hyperlipemia model was established by feeding the animals with high fat forage for 6 weeks and CI model established by occlusion of the unila-teral middle cerebral artery.For rats of acupuncture Ⅰ group,EA(1-3 mA,15 Hz) was applied to bilateral "Sanyinjiao"(SP 6) and "Fenglong"(ST 40) for 20 min every time,once daily for 10 days before CI.For rats of both acupuncture Ⅰ and Ⅱ groups,after CI,EA was applied to SP 6,ST 40,"Baihui"(GV 20) and "Shuigou"(GV 26) were punctured with filiform needles and stimulated by twirled the needle with hand continuously for 1 min,once daily for 7 days.The apoptotic cells of hippocampal CA 3 area were displayed by TUNEL(terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling) method.CB antibody staining with immunohistochemistry was used to show CB-positive cells which were observed by optic microscope.Results In comparison with control group,the percentage of apoptotic cells of the hippocampal CA 3 area in model group increased considerably(P

Objective To study the dose-and time-effects of X-ray irradiation on the expression of Pokemon gene in A549 cells of human lung adenocarcinoma.Methods A549 cells were cultured in vitro and exposed to X-rays with the doses of 2,4,6 and 8 Gy,respectively.Untreated A549 cells were used as control group.The relative levels of Pokemon mRNA expression in the cells were detected by using quantitative real-time PCR at 2,4,8,12,24,48 and 72 h after irradiation.Results The Pokemon mRNA expression levels decreased in the early period after irradiation(except 2 and 4 h after irradiation in 2 Gy group)and then increased in the later stage(48 h after irradiation)with significant statistical differences at the most time points in comparison with the control group(t=3.40-154.76,P<0.05).Conclusions Higher doses of X-rays may degrade the expression of Pokemon mRNA in the human A549 cells and induce apoptosis in the early period,hut also may upgrade its expression in the later period, which might be correlated with the cell cycle regulation and DNA damage repair in the A549 cells.

Objective We tried to observe the effects of Chinese herb fumigation and washing combined with electromyographic biofeedback on stroke patients with muscle cramp on limbs.Methods 84 patients who had muscle cramp on limbs were selected and divided into two groups randomly,namely the intervention group and the control group and both groups had 42 stroke patients.The intervention group was treated with routine treatment,Chinese herbal fumigation and washing and electromyographic biofeedback treatment.The control group received only routine treatment and electromyographic biofeedback treatment.We had compared and analyzed the Ashworth Spasticity Scale and the Daily Life Abihty Score (Barthel index) of the two groups at the time of the pre therapy,two weeks after the treatment and at the end of the treatment(after four weeks),respectively.Results There were no significant differences between the two groups in Barthel index,however,there were significant differences in Ashworth Spasticity Scale scores between the two groups four weeks after treatment,t=-3.84,P ＜ 0.05.Conclusions The effect of Chinese herb fumigation and washing combining with the electromyo-graphic biofeedback treatment is better than usage of the electromyographic biofeedback treatment alone on stroke patients with muscle cramp on limbs.
