China Medical Equipment 2014;(12):130-132
Objective: To study the acute myocardial infarction (Acute myocardial infarction, AMI) rescue emergency care patient outcomes analysis process optimization (Emergency care process optimization, ECPO). Methods: From July 2012 to May 2013, our hospital 98 cases of AMI patients as research subjects, both ST-segment elevation and emergency hospital. Patients included in the control group (47 cases) before this, the patient is classified after the cut-off point in the observation group (51 cases). The control group received routine emergency care programs, and the observation group ECPO measures to rescue the effect of index contrast two levels, two-hospital AMI recurrence rate and re- PCI hospital treatment ratio, and two groups of patients satisfaction with care process for the situation. Results: The expansion of time and out of the emergency room observation group and emergency balloon time was significantly less than the control group, the difference was statistically significant(t=3.577, t=2.928; P<0.05). AMI hospital observation group relapse rate and re-PCI hospital treatment ratios were significantly less than the control group, the difference was statistically significant(x2=4.006, x2=4.581; P<0.05). The patients' satisfaction for the care process was significantly higher, the difference was statistically significant(x2=11.055, P<0.05). Conclusion: In patients with AMI ECPO rescue measures, the effect is very significant, and can effectively shorten the rescue time and increase the success rate, it is recommended clinical applications.

3.Effect of Ginseng Rhizome Saponin by cAMP and cGMP in the Formation of the E~*-Rosette of the Human Lymphocytes
Chinese Journal of Immunology 1985;0(01):-
The concentration of the cyclic nucleotides and its relation with the E-RFC were determined by using ginseng rhizome saponin in human peripharal leukocytes.Result were compared with the ckange of the E-RFC by using cAMP.cGMP and theophylline. Experiments proved that girseng rhizome saponin mainly affected the lymphocytes and significantly increased the concentration of cAMP and cGMP,especially,the cAMP. Lymphocytes were incubated with ginseng rhizome saponin to form Et-RFC. It is different where lymphocytes were incubated in diffierent times. cAMP and theophylline reduced the Ea-RFC and Et-RFC, cGMP increased the Ea— RFC,but no effect to the Et-RFC. Ginseng rhizome or root saponin could promote the Ea-RFC,but inhibited the Et-RFC. It is consistent with the effect of both cAMP and cGMP. Experiments showed that ginseng rhizome saponin increased the concentration of cAMP and cGMP in human lyphocytes followed by that of E-RFC.It was suggested that the change of cyclic nucleotides in lymphocytes may be a mechanism of adjusting the immunity on cell level.

Journal of Environment and Health 2007;0(09):-
Objective To establish a new kinetic fluorimetry method for the determination of trace catechol in waste water. Methods Trace catechol inhibited the catalytic oxidation of pyronine Y by potassium periodate in the presence of vanadium(the catalyst) in H2SO4 medium. A linear relation appeared between the concentration of catachol and the changing of catalyzed reaction speed. A new inhibitory kinetic fluorimetry method for the determination of trace catechol in waste water was established. Results The linear range of determination was 10.0-1 500.0 ?g/L,and the detection limit was 7.8 ?g/L. The RSDs and recovery rates of the method were 2.42%-2.71%,and 98.3%-103.3% respectively. Conclusion This method is simple and sensitive for the determination of trace catechol in waste water with satisfactory results.

Journal of Environment and Health 1993;0(01):-
Objective To establish a new kinetic fluorimetry method for the determination of trace nickel in human hair samples. Methods The method was based on the catalysis of nickel on the oxidation of fluorescein(CF) by hydrogen peroxide in an almost neutral medium. As nickel is present, the fluorescence intensity of the solution decreases. Results The wavelength of excitation was 492 nm and the wavelength of emission was 516 nm. The reaction was optimized at 100 ℃ for 10 min. The linear range of determination was 4.0-80.0 ?g/L and the detection limit was 2.2 ?g/L . The RSDs and recovery rates of the method were 2.6%-3.2%, and 96.7%-102.8% respectively. Conclusion This method is simple, rapid and sensitive for the determination of trace nickel in human hair samples.

Objective:To compare the adverse reactions for patients with brain tumor before and after gamma knife treatment, and analyze the application effect about pertinency nursing intervention measures.Methods: From January 2015 to February 2016, 80 patients with brain tumor who were treated by gamma knife were divided in observation group (40 cases, received pertinency nursing) and control group(40 cases, received normal nursing intervention) with random number table. And to compare the nursing effect difference between the two goups.Results: The average intracranial pressure of the two groups was (186.4±34.2)mmH2O before treatment; it was (232.3±41.5)mmH2O after treatment; and the difference was statistical significant (t=7.634,P=7.634). The observation group were lower than control group in epilepsy, scalp rupture and scalp infection rate, and the difference was statistical significant(x2=4.211,x2=5.541,x2=3.914;P<0.05). The average intracranial pressure and recovery time of observation group were (195.3±36.9)mm H2O and (13.4±3.2)d, respectively, after treatment. Both of the two indexes were lower than (218.2±42.5) mmH2O and (16.1±3.7)d of control group, and the difference was statistical significant(t=2.573, t=3.491;P<0.05). The observation group were lower than control group in occurrence rates of headache, vomiting and papilledema, and the difference were statistical significant (x2=4.114, x2=5.000,x2=4.211;P<0.05); the observation group was higher than control group for treatment satisfaction, and the difference was statistical significant (x2=5.165,P<0.05).Conclusion: The intracranial pressure of brain tumor patients will significantly rise after gamma knife treatment, and the pertinency nursing can reduce the occurrence rates of adverse reaction, intracranial pressure and symptom of encephaledema.

The changes of skeletal muscle mitochondral monoamine oxidase (MAO) activity in rats fed with low Se grains from a Keshan-disease area were observed. The rats were killed at the time for feeding 30, 60 and 90 days respectiely. The mitochondrium of skeletal muscle was isolated MAO activity was determined with fluorescent methed. The results showed that in low-Se group the mitochondrial MAO activity was significantly decreased only at the time for 90 days feeding however GSH-px activity in red blood cells and Se content in plasma were significantly decreased at all experimental period as compared to Se-supplemented or stock died group.

Objective To verify the ability of distal ends of internal mammary artery and vein used as recipient vessels on breast and chest wall reconstruction. Methods Four bilateral (left 2 and right 2) scent pig buttock island flaps pedicled circle deep iliac artery and vein were used by comparing the different hemodynamic parameters (pressure; flux volume; perfusion unions) between the original pedicl artery (deep iliac artery), proximal and distal ends of internal mammary artery. The free flaps were transplantated by anastomosed end-end to the distal-ends of internal mammary artery and vein after the proximal ends were ligated. Results The pressure of distal end of internal mammary artery was 61%-65% of the pressure with original pedicl artery (deep iliac artery), the immediate volume of anastomasis stoma was a little lower than that of original pedicl artery. The flap, 15 cm?30 cm?2 cm in size, completely survived more than 14 days after operation. Conclusion The slightly decreased distal arterial pressure does not compromise flap survival. Bilateral scent pig buttock island flap pedicled circle deep iliac artery and vein is an ideal animal flap model. This hymodynamic model can be widely used .
