Objective:To analyze the effect of first aid knowledge and skills training for women in poverty-stricken areas, and summarize the importance of first aid knowledge and skills for women in poverty-stricken families.Methods:By cluster sampling, 318 women from poverty-stricken families who participated in the vocational training class in Zhen’an County, Shaanxi Province were trained in first aid knowledge and skills. The mastery of first aid knowledge before and after the training was evaluated by questionnaire survey, and the mastery of first aid skills before and after the training was evaluated by on-site assessment.Results:After the theoretical training of women from poor families, the awareness rate ranked in the top five were fire, poisoning, burns, heatstroke and earthquake first aid measures, with a knowledge rate of 98.1%(312/318),96.5%(307/318), 95.3%(303/318), 93.4%(297/318), 91.8%(292/318), which were statistically different from the pre-training rate, 88.0%(280/318), 84.0%(267/318), 78.4%(249/318), 43.4%(138/318), 72.6%(231/318), ( χ2 value was 15.03-183.89, all P<0.01). The pass rate of post-training cardiopulmonary resuscitation, hemostatic, dressing, and carrying skills of poor family women were 69.8% (222/318) , 52.8% (168/318) , 50.0% (159/318) , 76.1% (242/318) , respectively, which were statistically different from pre-training, 1.3%(4/318), 2.2%(7/318), 1.9%(6/318), 6.9%(22/318), ( χ2 value was 191.57-326.19, all P<0.01). Conclusion:The effect of training on first aid knowledge and skills of women in poverty-stricken families is significant, and a long-term training mechanism can be established.

Objective To assess the influence of pre-exposure to non-ablating ultrasound on the effect of high intensity focused ultrasound(HIFU)ablation.Methods Forty rabbits with transplanted VX2 tumors on their livers were divided into three pre-exposure groups(60 W,80 W and 100 W)and a control group(O W),with 10 rabbits in each group.Each group was pre-exposed to lower intensity focused ultrasound at the corresponding power.From each group,5 rabbits were randomly selected to be exposed to HIFU on the next day.Each group received 14scans.The rabbits were sacrificed 24 h later to take tissue samples for tfipheny tetrazolium chloride(TTC)staining to measure the amount of coagulative necrosis.Hematoxylin and eosin(HE)staining and succinate dehydrogenase (SDH)were also measured to observe the structure and activation of pre-exposed tumors.Results After HIFU exposure,the ablated volumes increased with pre-exposure acoustic intensity,and all volumes were larger than those in the control group.The ablating efficiency in the 100 W group was the highest.The pre-exposure did not itself ablate tumor tissue,but in the 80 W and 100 W groups the structure and activation of the tissues changed.Those in the 60 W group were not obviously altered.Conclusion Prior exposure to non-ablating ultrasound can highly enhance the efficacy of HIFU ablation.

Objective To observe the pathological regression of rabbit liver after the low-dose irradiation with high intensity focused ultrasound (HIFU), and to explore the role and mechanism of the irradiation in changing acoustic environment of rabbit liver. Methods Pathological study was performed in 10 New Zealand white rabbits, the livers were observed under light and electron microscope. The observation was done immediately after low-dose HIFU irradiation and in 2, 3, 5, 7 days after the low-dose irradiation with HIFU. Results Light microscope changes: Edema existed in hepatocytes after irradiation instantly, congestion and aggravated edema were found at 2-3 days, then the injured cells recovered gradually. Electron microscope changes: Detached endothelial cells of hepatic sinusoid and swelling organelles were observed after irradiation, while 2 or 3 days later, erythrocyte aggregation was found in hepatic sinusoid and cavitation was found in cytoplasm. Thereafter, organelles swelling reduced till resumed to normal. Conclusion Low-dose HIFU irradiation can make corresponding changes to the acoustic environment of rabbit liver.

Objective To detect the difference of the light sensitivity in the central visual field between normal people and type Ⅱ diabetic patients without diabetic retinopathy , and evaluate the effect of perimetric examination in early diagnosis of diabetic retinopathy. Methods The light sensitivity at the 80 locations in the central field was measured by Dicon field analyzer (model TKS 4000) in 76 normal eyes of 44 normal volunteers aged from 45 to 72 years and 75 eyes of 40 type Ⅱ diabetic patients without retinopathy aged from 46 to 71 years. Results For the diabetic patients without diabetic retinopathy, the light sensitivity of locations decreased by 4 8 dB,and there were some decreased light sensitivity areas. The mean light sensitivity of three zones of the central field had significant reduction in the diabetic patients as compared with the control group( P

Objective To analyse the distribution and evolution law of TCM syndrome for elderly hypertension (EH), to provide evidence for syndrome standardization study. Methods Case history of 2 029 EH patients during recent ten years were investigated in the way of epidemiology. The main and complicated syndrome types were studied. Results The main syndrome types of EH were yin deficiency of liver and kidney (40.0%), kidney qi deficiency (28.4%), hyperactivity of liver-yang (9.7%), excessive accumulation of phlegm-dampness (7.4%), collateral obstruction by blood stasis (6.6%), phlegm and blood stasis (5.7%), liver-fire hyperactivity (1.1%).
