ABSTRACT
Objective To evaluate the clinical application of TCM nursing therapies and identify the problems during the therapy implementation, in order to explore the countermeasures to promote its clinical improvement. Methods A descriptive cross-sectional study was conducted,and a self-designed questionnaire was employed to investigate 218 nurses from 148 grade A class three TCM hospitals in China. Results 25 TCM nursing therapies were implemented in these hospitals. Ear acupressure therapy was the most frequently implemented,accounting for 83.5%(182/218);while wax therapy was the least implemented, accounting for 7.8%(17/218). The implementation frequency of these technologies varied significantly, 0~860 times a week. The top three of them were acupoint application therapy, hot compression of Chinese medicine and ear acupoints therapy.TCM nursing therapies were considered to be the most frequently used in insomnia, headache, edema, arthralgia, cold, epigastric pain, hypochondriac pain and fever.Storage of TCM nurses,lacking of TCM knowledge and inapposite therapy implementation were the main problems in the application. Conclusions Scientific and rational allocation of human resources, cultivation of the TCM-specific nursing professional, enhancement of nurses'awareness of Chinese medicine, establishment of a reasonable charging standard, and strengthening the risk management in implementation will promote its clinical development.
ABSTRACT
Objective To assess the efficacy and safety of multimedia visual training system for ambly-opic children through a randomized, controlled clinical trial. Methods A total of 203 amblyopic children (253 eyes) ages 3 to 12 years were randomly divided into a study group (100 patients, 170 eyes) and a control group (103 patients, 183 eyes). The study group received multimedia training system; while the control group received conventional integrated therapies. Best corrected visual acuity was examined 3 and 6 months after treatment. The efficacy and safety of multimedia visual training system for amblyopic children was assessed by comparing the ef-fect of treatment in both groups. Results 6 months after treatment, the total effectiveness rate was 74.1% in the study group and 52.5% in the control group, and there was a statistical difference (P < 0.0001). The effective-ness rate for refractive amblyopia was higher in the study group than in the control group (80.5% vs. 50.8%), and there was a significant difference (P < 0.001). As compared with the effectiveness rate for different ages, the subgroups of 3 to 6 years and 7 to 12 years in the study group was 80.8% and 58.0%, much higher than those in the control group (54.9% and 43.9%), and there were statistical differences(P < 0.001 and P < 0.05). Conclusions The efficacy of multimedia visual training system is superior to that of the traditional treatment , especially for refractive amblyopia. It is effective in all age groups.
ABSTRACT
OBJECTIVE:To improve the formulation of Kangfu cream,in order to increase the stability of it. METHODS:Ac-cording to the problem that demulsion of zinc oxide and poor stability of Kangfu cream,orthogonal test was used to optimize the formulation of cream matrix with oil phase ratio (stearic acid-white vaseline-glycerol monostearate),with the amount of polysor-bate 80,triethanolamine and SG-10 as factors,using comprehensive score of glossiness,delicacy,consistence,coating and stratifi-cation(10 points as full mark)as index. The stability of the cream was validated and investigated,such as compatibility,heat-re-sisting,cold-resistant,lighting. RESULTS:The formulation were as follows as 100 g cream containing stearic acid 8 g,white vase-line 8 g,glycerol monostearate 6 g,polysorbate 80 4 g,triethanolamine 3 g,SG-10 2 g and appropriate amount of water. The comprehensive scores of the cream were >9.5 points (n=3). Compared with the cream prepared by previous formulation,the cream prepared by modified formulation had no significant change in appearance and color,and demulsion and layering hadn’t been found. CONCLUSIONS:Kangfu cream with better stability than original formulation is successfully prepared.
ABSTRACT
Objective To establish a method for the determination of Ca2 + cations in the nutritive food by ion chromatography.Methods After being digested by the mixture of nitric acid and perchloric acid,the Ca2+ cations in the nutritive food were determined by ion chromatography(IC).Results The optimum chromatographic conditions were studied thoroughly,the linear range was 0.10-500 mg/L,r=0.9998.The lowest detection limit of Ca2+ cations in nutritive food was 0.02 mg/L,RSDs were 0.50%-4.00%,the rates of recovery tested by the standard addition method were in the range of 95.0%-103.0%.Conclusion This method is simple,fast,sensitive and accurate.
ABSTRACT
Objective To establish a method to determine dicofol and eight pyrethroid pesticides residues in vegetables and fruits by gas chromatography.Methods The crushed samples were extracted with organic solvent,then the extract was analyzed by DM-17 capillary column gas chromatography after being purified by PestiCarb-NH2 cartridge and silica cartridge solid phase extraction.Results The detection curve covered the linear range of 0.10-2.0 ?g/ml .The minimum detection limit was 0.011-0.090 ?g/kg.The rates of recovery were 85.4%-105%.The variable coefficient(RSD) was under 7.0%.Conclusion This method has the advantages of less disturb, simple and high accuracy, and it can be applicable to the routine analysis of dicofol and pyrethroid pesticides residues.
