ABSTRACT
Objective To design a multi-function first-aid module integrating instruments with the box to solve the existing problems in integration, operation, deployment, withdrawal, environmental adaptability and etc, so as to realize integrated storage, transport and operation of the instruments. Methods The module had its structure, modes of deployment and withdrawal, instruments buffering and vibration isolation, ergonomics and etc designed with the technologies of integrating box and instruments, integration, buffering and vibration isolation, centralized oxygen and power supply as well as the methods of system modeling,structure simulation and CAD.Results The first-aid module was gifted with the functions of respiratory and circulatory rehabilitation,vital signs monitoring,emergency treatment of complex and multi injuries, which could be used as a 2 000 mm×800 mm×600 mm emergency treatment platform when deployed. There were 4 angles for adjusting the backboard to form anti-shock positions for the severe casualties.The module had the time for deployment and withdrawal not more than 5 min,and was easy to deploy,withdraw,transport and store.Conclusion The module behaves well in structure,function,layout,operation and military service when used for the treatment of the severe casualties in the tent-form field medical system,which contributes to enhancing the casualty treatment efficiency and prognosis.[Chinese Medi-cal Equipment Journal,2018,39(5):12-16]
ABSTRACT
Objective To develop a set of field tent hospital system to further enhance campaign-level medical support service. Methods The system had its service orientation, functional requirements, component unit and modular elements determined with system analysis. The technical architecture was realized with tent combined with boxes, and the system modules were designed with the method of integrated box and instruments.Results The system had its design executed from the aspects of layout,composition of grid tent,medical functional units,support unit and packaging unit,which was applied in a series of military medical support operations in foreign countries and China as well as in the construction of national medical emergency rescue forces. Conclusion The system gains advantages in modularity, integration, completing, informatization and standardization,and thus greatly enhances the military medical support ability and national emergency medical rescue ability in China.[Chinese Medical Equipment Journal,2018,39(5):1-6,16]
ABSTRACT
Objective To design a whole process management information system of the field medical equipment.Methods According to the problems found in the management of medical equipment, the functional requirements of different user systems were determined.The system was developed with combined Java and C languages,Eclipse and Visual Studio 2012, and was connected into military integrated information network according to security requirements.Results By applying the whole process management system of the field medical equipment, all process data could be managed from purchasing, warehousing,distribution,use,maintenance,R&D and so on.Conclusion By applying this system,the management of the field medical equipment is improved, functional requirements are met of all levels of health equipment management, the platform for data sharing among relevant departments is set up,and the static mode is transformed into a real-time,dynamic and whole process one for field medical equipment management.
ABSTRACT
Objective To observe the clinical efficacy of Tangqianping Granules in the treatment for patients with pre-diabetes. Methods Totally 140 patients with pre-diabetes were divided into treatment group and control group through random number table method, with 70 cases in each group. Both groups had lifestyle intervention and health education, such as diet and exercise. The control group was treated with metformin hydrochloride enteric-coated tablets, 0.25 g per time, three times a day, orally. The treatment group was treated with Tangqianping Granules on the basis of the control group, one dosage per day, twice a day, orally. The treatment course for both groups were 3 months. Clinical efficacy of both groups were evaluated. TCM symptom scores, blood glucose, lipid level and prognosis were observed. Results The total effective rate was 89.9％ (62/69) in the treatment group and 58.8％ (40/68) in the control group, and the treatment group was better than the control group, with statistical significance (P＜0.05). Compared with before treatment, TCM symptom scores of the two groups after treatment were significantly lower, with statistical significance (P＜0.05). After treatment, TCM symptom scores in the treatment group were lower than those in the control group, with statistical significance (P＜0.05). Compared with before treatment, fasting blood glucose (FBG), glycosylated hemoglobin (Hb A1 c), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), fasting insulin (FINS), and insulin resistance index (HOMA-IR) decreased after treatment in both groups, with statistical significance (P＜0.05). After treatment, the levels of FBG and TC in the treatment group were lower than those in the control group, with statistical significance (P＜0.05). The rate of reversal of pre-diabetes and the incidence of new diabetes after treatment in the treatment group were better than those in the control group (P＜0.05). Conclusion Intervention of Tangqianping Granules in the pre-diabetic population has significant clinical efficacy, which can effectively prevent the occurrence of diabetes.
ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of polydatin on phospholipase A(2) in lung tissues in rats with endotoxic shock.</p><p><b>METHODS</b>Thirty-two healthy male Wistar rats were employed in this study. A total of 8 rats received normal saline intravenously (control group), 8 rats received 10 mg/kg of endotoxin (endotoxic shock group), 8 rats received 1 mg/kg of polydatin after endotoxin injection (polydatin treatment group), and 8 rats received 1 mg/kg of polydatin (polydatin prevention group) 30 minutes before endotoxin injection. Mean arterial pressure was measured once half an hour. Lung tissues were collected 6 hours later. Phospholipase A(2) activity was measured with acid titration. The gene expression of secretory phospholipase A(2) type IIA was detected with reverse transcription polymerase chain reaction. Meanwhile, the histological changes of the lungs among four groups were compared through microscopic examination.</p><p><b>RESULTS</b>Phospholipase A(2) activity and the gene expression of secretory phospholipase A(2) type IIA increased after endotoxin injection, but polydatin could inhibit these effects of endotoxin. Obvious morphological evidence could be found in the lung pathological sections and the protective effect of polydatin was most significant in the polydatin prevention group.</p><p><b>CONCLUSIONS</b>Polydatin has prophylactic and therapeutic effects (the former is more distinct than the latter) on acutely injured lungs in rats with endotoxic shock and which suggests that polydatin may be a phospholipase A(2) inhibitor.</p>
