ABSTRACT
Objective To investigate the awareness of osteoporosis and its influential factors in middle-aged and older people. Methods By using self-designed questionnaire, 354 middle-aged and old people were investigated as to their awarness of osteoporosis in Chajiao street community in Guangzhou. Among them, 58 people were measured the bone density in the calcaneal bone by Ultrasound. Results The average score of the questionnaire was 9.46 ± 5.13, and the accuracy was 39.4%. In the diagnosis and treatment, the accuracy was just 17.8%. The diet (the accuracy in 54%) and sport (the accuracy in 50.3%) were good. The statistical analyses showed the linear relationship between the T value of bone density and the age (P = 0.021), between the T value and the score (P = 0.047). Wilcoxon rank sum test found that the T value between female and male was significantly different (Z = -3.749, P < 0.000). With multiple linear regression analysis, the T value had a linear correlation with the score (F = 4.224, P = 0.045) positively. Conclusions Currently, the awareness of osteoporosis in the middle-aged and old people was inadequate. To better prevent osteoporosis, the propogation of knowledge and guidance provided by clinicians in osteoporosis should be improved necessarily and emergently.
ABSTRACT
Objective To investigate the status of smoking and drinking among the officers and soldiers in associated logistics army,analyze the feature and primary cause of service men' s smoking and drinking,and provide scientific reference for the intervention measures.Methods A questionnaire survey was conducted among 1102 officers and soldiers in associated logistics army in Guangdong.Results 95.6％ officers and soldiers knew smoking was harmful to health,and 94.1％ knew drinking was harmful to health.The rate of recognition of smoking and drinking harm in officers,high-ranking soldiers and obligatory soldiers were significantly different (P ＜0.001 ),and the rate of recognition in different educational background wasn't significantly different (P ＞ 0.05 ).34.5％ officers and soldiers smoked or drank for reducing pressure.The total smoking or drinking rate was 64.7％or 72.6％ respectively in the service men.The rate of smoking and drinking in the officers and soldiers were significantly different (P＜0.01).In total 713 smokers,28.3％ smoked occasionally,25.8％ often,and 45.9％ heavily.In 800 drinkers,56.6％ drank lightly,32.3％ moderately,and 11.1％ heavily.In all drinkers,45.9％ drank beer,11.5 ％ drank distillate spirit,12.1％ drank port wine,and 5.5 ％ drank imported wine and spirits.Officers drank beer or distillate spirit dominantly (49.2％ and 30.8％,respectively),while high-rank soldiers and obligatory soldiers (40.6％ and 59.3％,respectively) drank beer dominantly.16.9％ officers,1.6％ high-rank soldiers and 0％ obligatory soldier respectively drank heavily distillate spirit ( ＞ 250 g every time).Conclusion Heath education and good environment for service men should be provided to give up smoking and drinking,thus to further prohibit smoking and drinking in the army.
ABSTRACT
Objective To investigate the epidemiological information of patients in pre-hospital medical care for our large and medium-sized cities and probe the patients' characteristic. Method The data in 2008 were exported from the computer databases of 8 large and medium-sized cities' emergency medical centers in our country.The thorough records of data were conducted to statistical analysis. Results ( 1 ) The scheduling time, running time, rescue time, returning time, total time and service radius in the pre-hospital medical care group were 2.16± 1.10(min), 14.01 ±6.82(min), 12.12±5.96(min), 14.08± 6.85(min), 42.34± 20.21(min)and 8.50±4.18(km), and the above parameter in the non-death group were 2.19 ± 1.13(min), 14.15 ± 7.14(min),11.60±6.72(min), 14.92 ±6.89(min), 41.86± 19.53(minutes) and 8.63±4.31(Km), and the above parameter in the death group were 2.10± 1.08(min), 13.68 ± 7.14(min), 25.25 ± 12.34(min), 13.75±6.48(min), 54.74 ± 25.47(min) and 7.86± 3.91(Km), and the above parameter in the non-sudden cardiac death group were2.09± 1.03(min), 13.58±6.78(min), 25.53± 12.34(min), 13.60± 6.54(min), 53.79±23.77(min) and 7.67 ± 3.86(Km), and the above parameter in the sudden cardiac death group were 2.12 ±1.02(min), 14.10±7.05(min), 24.79± 12.08(min), 13.79±6.61(min), 54. 80 ± 25. 36( min) and 7.90±3.92(Km) respectively. The scheduling time, running time, returning time and service radius in the death group were less than those of the non-death group, but the rescue time and total time of the former were more than those of the latter respectively ( P ＜ 0.05 or P ＜ 0. 001 ). The scheduling time and returning time didn' t have significant difference between the sudden cardiac death group and the non-sudden cardiac death group respectively ( P ＞ 0.05), but the running time, total time and service radius of the sudden cardiac death group were more than those of the non-sudden cardiac death group, and the rescue time of the former was less than that of the latter respectively ( P ＜ 0.05 or P ＜ 0.001 ). (2)The patients' amount in pre-hospital medical care group, the non-death group, the death group, the non-sudden cardiac death group and the sudden cardiac death group were at most in first quarter, and the least time slice of patients' amount were 4:00～ 6:00, 4:00～6:00, 4:00～ 6:00, 22:00～ 24:00, 2:00～4:00 respectively, and the most time slice of patients' amount were 20:00～ 22:00, 20:00～22:00, 8:00～ 10:00, 2:00 ～ 4:00, 8:00 ～ 10:00 respectively. (3)In 241 876 cases of pre-hospital medical care group, the patients' amount of trauma was at most, whose age grades was by far among21 ～50, and the others in sequence were nervous system, circulatory system, other group, digestive system, respiratory system and poisoning group respectively, whose age grades in nervous system, circulatory system and respiratory system was by far above 51, especially above 70. The patients' age grades in other group and digestive system had two climax age groups, which the one was 21 ～ 30, and the other was above 70. The patients' age grades in poisoning group was by far among 21 ～ 50, which the patients' amount of acute alcoholism was at the most. (4) In 12 568 cases of death group, the death amount of circulatory system, other group, respiratory system, nervous system and digestive system ranked at the lst,2nd,4th,5th 8th respectively, whose age grades was by far above 51, especially above 70,and the patients' amount of sudden cardiac death was at the most in the death amount of circulatory system. The death amount of trauma and poisoning group ranked at the 3rd, 6th respectively, whose age grades was by far among 21 ～ 50. (5)The total amount, the death amount and the sudden cardiac death amount of male patients were more than those of female patients. (6)The percentage of the death group to the pre-hospital medical care group was 5.20%, and the percentage of the sudden cardiac death group to the pre-hospital medical care group was 1.29%,and the percentage of the sudden cardiac death group to the death group was 24.87 %, and the percentage of the sudden cardiac death group to the circulatory system group was 67.33 %. Conclusions ( 1 )The trauma and the sudden cardiac death are the overriding reason of disease and the overriding reason of death in our large and medium-sized cities respectively. (2) It is very important to cut the death rate of the middle-old age patients by strengthening prevention and cure of cardiovascular and cerebrovascular diseases, discerning the critical illness early and improving the level of pre-hospital medical care. (3)It is a strong method to decrease the total amount and the death amount of the trauma, especially in traffic accident, by strengthening safety in production, observing traffic regulation and enhancing the legal awareness.
ABSTRACT
Objective To investigate the clinical efficacy and safety of hyperthermic intraperitoneal perfusion chemotherapy (HIPC) in treatment of advanced colorectal cancer.Methods The Meta-analysis was applied to analyze 8 randomized controlled quantitative studies published at domestic and abroad.These patients treated by HIPC after radical operation with colorectal cancer were included for the treatment group,and those treated only by radical operation with colorectal cancer for the control group.Relative risk (RR) of outcome variable of 3-year and 5-year survival rate and safety between the two groups were compared.Results There were 8 selected literatures,including 1 501 cases,in which 765 cases for treatment group,and 736 cases for control group.RR of 5-year survival rate of the total patients was 2.39 (95% CI:1.66-3.45).RR of 3-year survival rate of the total patients was 2.13 (95% CI:1.45-3.13).The results demonstrated that HIPC could improve 5-year and 3-year survival rate,and sensitivity analysis confirmed the conclusions more reliable.The security was described in 5 literatures,the available information showed smaller potential security issue.Conclusions HIPC after radical operation of advanced colorectal cancer can increase 5-year and 3-year survival rate of patients,improve the prognosis of patients.Whether patients with increased incidence of postoperative complications related to the HIPC is no clear-cut conclusions for lack of related research.
