ABSTRACT
Objective@#To understand the prevalence of gynecologic diseases among married female workers.@*Methods@#The data of married female workers who underwent occupational health examination in a physical examination center from January to December 2017 were collected. The relationship between the detection of common gynecological diseases, age and occupational types examined by gynecological routine, TCT, breast B-mode ultrasound, uterus and appendix B-mode ultrasound were analyzed.@*Results@#Among the 1142 female workers, the total detection rate of reproductive tract infections was 67.25% (768/1142), the total detection rate of breast-related diseases was 75.22% (859/1142) ; the total detection rate of gynecological tumors and benign lesions was 14.71% (168/1142). The detection rate of breast hyperplasia was the highest 67.08% (766/1142), followed by vaginitis 51.66% (590/1142). Among the abnormalities detected in breast-related diseases, gynecological tumors and benign lesions, the highest detection rate was found in public institutions (85.66% and 27.13%), and the lowest was found in factory workers (70.24% and 7.89%). With the increase of age, the detection rate of breastrelated diseases (breast hyperplasia, breast cyst), gynecological tumors, benign lesions (uterine myoma), and Nessler's cyst abnormalities in married female workers increased (χ2trend=7.647、21.653、107.411、53.802, P<0.05), while the detection rate of columnar epithelium of cervix decreased (χ2trend=7.404, P<0.05). There was no significant difference in the total detection rate of reproductive tract infectious diseases (vaginitis, cervical polyps, cervical hypertrophy) among married famale workers of different ages (P<0.05) .@*Conclusion@#The common gynecological diseases of married female workers are affected by many factors such as age and occupation. Health examination and health education should be carried out regularly to reduce the incidence of gynecological diseases among female workers according to different ages and occupations.
ABSTRACT
Objective@#To study the hearing status and analyze the related influencing factors in noise-exposed workers in an automobile manufacture enterprise, and put forward suggestions for prevention of noise-induced hearing loss.@*Methods@#Noise exposure level testing, audiometry testing and questionnaires were performed for noise exposed workers in the automobile manufacture enterprise. To analyze the relationship between different factors and noise-induced hearing loss by cumulative noise exposure(CNE) calculated 8-hour continuous A-weighted equivalent noise level and seniority.@*Results@#The detection rate of hearing loss in noise-exposed workers was 22.8%. The noise exposure intensity of stamping workshop is higher than other workshop, and the hearing loss detection rate of stamping workshop workers is higher than other workshop workers. The detection rate of hearing loss has significant difference in LAeq·8 h, seniority, CNE, age, high temperature and wearing earplugs (P<0.05). The results of logistic regression analysis showed that CNE, age and high-temperature were risk factors for noise-induced hearing loss (P<0.05 and OR>1) and there was an increasing tendency of hearing loss with increase in length of service and CNE, while using of earplugs was a protective factor (P<0.05 and OR<1). With the increase of CNE, the incidence of hearing loss is the rising trend.@*Conclusion@#It is suggested to strengthen the noise control and individual protection and improve the high-temperature working environment, which plays an important role in reducing the occurrence of noise-induced hearing loss.
ABSTRACT
OBJECTIVE: To analyze the effect of occupational noise exposure on reproductive function in Chinese female workers.METHODS: The published literatures that showed the relationship between occupational noise exposure and female workers' reproductive function from Chinese National Knowledge Infrastructure,Wanfang Data,Chinese Biology Medicine Database and China Science and Technology Periodical Database from 1985 to 2016 were collected,screened and analyzed using bibliometric method.The Rev Man 5.2 software was used to calculate the pooled odds ratio(OR) and the 95%confidence interval(CI).RESULTS: A total of 25 original research papers were included.The occupational exposure to noise was significantly associated with abnormality of female menstrual cycle(OR = 2.26,95% CI: 1.70-3.01),dysmenorrheal(OR = 2.21,95% CI: 1.78-2.75),abnormal menstrual period(OR = 2.11,95% CI: 1.40-3.18),abnormal menstrual blood volume(OR = 1.73,95% CI: 1.34-2.23),pregnancy-induced hypertension(OR = 1.82,95% CI: 1.49-2.22),anemia in pregnancy(OR = 1.71,95% CI: 1.25-2.34),threatened abortion(OR = 1.98,95% CI: 1.23-3.20),spontaneous abortion(OR = 1.76,95% CI: 1.49-2.08),stillbirths(OR = 1.61,95% CI: 1.22-2.13),premature birth(OR = 1.57,95% CI: 1.36-1.81),neonatal low birth weight(OR = 1.66,95% CI: 1.39-1.98),and congenital malformations(OR = 1.58,95% CI: 1.10-2.27) compared with the controls(P<0.01).There was a doseresponse relationship between the above-mentioned indicators and the intensity of noise exposure.Occupational noise exposure was not associated with over-term birth(OR = 1.32,95% CI: 0.81-2.15,P>0.05) compared with the controls.CONCLUSION: Occupational noise exposure can affect the reproductive function and pregnancy outcomes of female workers.It is suggested that pregnant women should not be engaged in noise operations.
ABSTRACT
Objective To study the clinical effect of continuous central venous pressure monitoring and select a better method for central venous pressure momtoring. Methods Continuous central venous pressure wag monitored by connecting pressure sensor to central venous catheter in 56 patients with open heart operation.At the same time routine monitoring method was used in the same central venous vein of the saine patient The CVP values from the two methods were compared for 100 times and analyzed the difference.Results The VCP values of the two groups had no statistical difference(P＞0.05).Conclusions Continuous monitoring by pressure sensor had advantages such as continuous data,dynamic,direct-viewing,Veracious and decreased chance of infection.It could reduce the workload of nurses and possessed more clinical value compared with routine monitoring method.
