BACKGROUND: The active ingredients of Chinese herbs, such as hongjingtian (rhodiola root, Radix Rhodiolae), srenshen (ginseng, Radix Ginseng), and danggui (Chinese angelica root, Radix Angelicae Sinensis),were found to be effective to inhibit the hypoxia injury.OBJECTIVE: To observe the protecting effect of xionggui diwan (Dripping Pills) on the hippocampal neurons from hypoxia by whole-cell recording patch-clamp technique.DESIGN: An auto-control observation on cells.SETTING: The 88 Hospital of Chinese PLA and Academy of Military Medical Science of Chinese PLA.MATERIALS: The experiment was performed during March to August 2002 in the Institute of Toxicology and Pharmacology of Academy of Military Medical Sciences of Chinese PLA. The neonatal Wistar rats, clean degree, were used. The hippocampal neuron cells out of 9 rats were cultured and divided into the control groups of before and after hypoxia-oxygenation,and xionggui diwan 1 × 10-6 mol/L and 10 × 10-6 mol/L groups. (Xionggui diwan was provided by the 88 Hospital of Chinese PLA and its active ingredient was the volatile ingredient of chuanxiong and danggui.)METHODS: While hypoxia-reoxygenation groups were not given any medicine intervention as control, the treatment of xionggui diwan 1×10-6mol/L was subdivided into xionggui diwan 1 × 10-6 mol/L + non-hypoxia and xionggui diwan 1 × 10-6 mol/L + hypoxia groups, and the treatment of xionggui diwan 10 × 10-6 mol/L was subdivided into xionggui diwan 10 × 10-6 mol/L + non-hypoxia and xionggui diwan 10 × 10-6 mol/L + hypoxia groups. The patch-clamp technique was performed to determine the Na+ and K+ currents of rat hippocampal neurons cultured in vitro before and after hypoxia-reoxygenation.MAIN OUTCOME MEASURES: The Na+ and K+ current amplitude of rat hippocampal neurons cultured in vitro.RESULTS:① The Na+ current amplitude of hippocampal neurons: After hypoxia-reoxygenation, it was significantly lower than that before [(-3.8±1.0, -10.3±0.5) nA, t=3.49, P < 0.01]. ② The K+ current amplitude of hippocampal neurons: After hypoxia-reoxygenation, the activation thresholdof K+ current was changed from -40 mV to -20 mV.③The Na+ and K+ currents of hippocampal neurons before and after hypoxia-reoxygenation with xionggui diwan pretreatment: Before hypoxia-reoxygenation, the ampli tudes of Ⅰ Na and J K of hippocampal neurons at the threshold point were very similar, without significant difference. After hypoxia-reoxygenation,those amplitudes of xionggui diwan 10.0 × 10-6 mol/L group were higher than that of xiongguidiwan 1.0 × 10-6 mol/L group [(-58.5±1.9, -6.9±1.4,-3.8±1.0) nA, t=7.51,P < 0.05].CONCLUSION: It was suggested that xionggui diwan propect the function of hippocampal neurons from hypoxia.

Antiaging effects or powdered Nelumbo nucifera seed were studied on wistar rats by comparing thcir viscera/body, T lymphocyte, SOD, LPO, GSH-Px between fed animals and control. Results showed that there was obvious increase of T lymphocyte in thorax cortex between fed and control, whereas distinct disparity of other indexes can not be found. These results implied that powdered N.nucifera seed has some functions of enforcing immunity.

Objective To evaluate the effect of implementing quality control circle (QCC)activities on nurses’ knowledge about ventilator-associated infection(VAP),as well as head-of-bed (HOB)elevation and incidence of VAP in patients.Methods 100 patients who used ventilators in an intensive care unit(ICU)of a hospital were ran-domly selected,50 patients were selected before the implementation of QCC(January-June,2013),and 50 were se-lected after the implementation of QCC (July-December,2103).Condition of nurses and patients who used ventila-tors before and after implementation of QCC were investigated.Results After implementing QCC,the scores of nurses’recognition on knowledge about causes and risks of VAP,significance and standard of HOB elevation,and HOB elevation≥ 30°were all higher than before implementing QCC;the total score was higher than before imple-menting QCC ([18.32±3.14]vs [7.98 ±1 .12],P <0.05 );patients’compliance to HOB elevation was higher than before implementing QCC([96.00%,n=48]vs [44.00%,n=22],P <0.05);incidence of VAP was lower than before implementing QCC ([4.00%,n =2]vs [36.00%,n =18],P <0.05).Conclusion Implementation of QCC activities can effectively improve ICU nurses’recognition on knowledge about VAP and enhance patients’ compliance to HOB elevation,as well as reduce the incidence of VAP,it is helpful for improving healthcare-associat-ed infection management quality.

Objective To develop infant thermal container with forced protection circuit so as to ensure its security. Methods Temperature database was set in thermal container and Cygnal F005 was used as intelligent controller. The state of the sensor was judged by comparison precisely. Double temperature controller was adopted to ensure normal working temperature. When the container went wrong, it could automatically switch to protection circuit to keep the temperature for infant. Results With precise temperature control and steady working station, the new type thermal container for infant could provide a safe and comfortable condition with clean air and fitting temperature and humidity. Conclusion The container is steady, accurate, safe and convenient.

OBJECTIVE:To discuss the drug resistance situation and influential factors of sputum culture positive tuberculosis patients in a specialized subject hospital. METHODS:The information of sputum culture positive tuberculosis inpatients were col-lected from Heze infectious disease hospital during Jan. 1st 2014 to Apr. 30th 2015;the results of drug sensitive test were analyzed retrospectively by using absolute concentration method. RESULTS:Among 259 patients,137 cases were drug-resistant(52.90%), among including 69(26.64%) mono-drug resistant cases,52(20.08%) poly-drug resistant cases,15(5.79%)multi-drug resistant cases and 1(0.39%)extensively drug resistant case;streptomycin (31.66%) and amikacin (15.44%) were drugs with the highest drug-resistant rate;there was no statistical significance in resistant rate between different genders and ages(P>0.05),the rate of drug resistance in first-treatment patients was 47.21%,and that of the re-treatment patients was 70.97%,the difference was statisti-cal significant(P<0.05). In addition to ethambutol and kanamycin,other all had mono-drug resistance,there were 27 combinations of poly-drug resistance and 9 combinations of multi-drug resistance. Logistic regression analysis showed that treatment history was a risk factor for drug-resistance,the risk of re-treatment patient was 2.734 times of first-treatment patients. CONCLUSIONS:Sputum culture positive tuberculosis inpatients patients have high drug resistance and complex spectrum in the hospital;we should pay great attention to the risk of drug resistance in senile patients and re-treatment patients,and rational use of streptomycin,amikacin,isoni-azid and capreomycin.
