Objective To explore the effects of microwave radiation from interphone on the electrocardiogram of occupational population. Methods 165 male security personnels (working age: 0.5-3.32 a) often exposed to microwave radiation from interphone and 80 male staffs (working age: 0.5-3.58 a) without exposure to microwave radiation in a same security guard company were selected for examination of electrocardiogram in June-July,2004. Results The prevalences of sinus arrhythmia,sinus bradycardia,and the total abnormal rate of electrocardiogram in exposure group were significantly higher than those in control group(P

37 diabetic patients and 49 normal subjects were examined with Goldmann-Weekers dark adaptometer.The results showed that the absolute thresholds of dark adaptation in each group of diabetic patients were higher than those in normal controls. The more severe retinopathy was, the higher was the absolute threshold.The patients with more damaged visual acuity showed worse dark adaptation. However the dark adaptation in patients with good visual acuity was also abnormal.lt is suggested that dark adaptation is more sensitive than visual acuity in determining the visual function of diabetic patients.

Objective To analyze the clinical application value of endometrial collector combined with liquid based cytology and histological examination for screening of endometrial cancer.Methods One hundred and eighty-two cases high-risk people with endometrial cancer in Songgang People's Hospital of Bao'an district of Shenzhen from June 2014 to December 2015 were collected,among them 71 patients with endometrial cancer were found in the patients who were diagnosed by pathological diagnosis,and the remaining 111 were not diagnosed with endometrial cancer.The material satisfaction,sample collection time of sample collection and endometrial curettage device were comparatively analyzed and also the cervical dilatation production rate,the amount of bleeding,pain score(VAS) were analyzed.The application value of endometrial collector combined with liquid based cytology and histological examination for screening of endometrial cancer was judged according to the results obtained.Results There was no significant difference between the two methods based on satisfaction(χ2=1.953,P=0.089).A methods of cervical endometrial expansion rate(3.85% vs.93.96%) and acquisition time((16.35±2.19) min vs.(11.23±4.26) min),bleeding volume((1.64±0.63) ml vs.(15.73±5.41) ml),VAS score((0.82±0.24) points vs.(4.34±2.43) points) were significantly lower than that of curettage sample collection method(χ2=16.473,P=0.000;t=5.733,P=0.034;t=11.183,P=0.000;t=3.618,P=0.043).With curettage pathological diagnosis as the gold standard,the specificity,sensitivity and diagnostic coincidence rate of endometrial biopsy combined with liquid based cytology and histological examination for screening endometrial carcinoma were respectively 94.51%,95.05% and 94.96%.Conclusion Compared with curettage sampling method,endometrial curettage collector has features of high success rate,short time,low pain and high security and the cervical dilation rate is low.Endometrial curettage collector can be combined with liquid based cytology and histology to examine and screen endometrial cancer.This methods is worth promoting.

Objective To investigate the efficacy and safety of hysteroscopic treatment for submucous uterine myoma.Methods From January 2000 to December 2004,a total of 168 women with submucous leiomyoma of the uterus were treated by hysteroscopy in our hospital.According to the type of the myomas,electro-resection was performed in different ways.For the patients with massive hemorrhage or older than 45 years,the endometrium was resected during the operation.Results The operation was completed in all the cases within 5 to 65 minutes mean,(27.6?12.1)minutes].The mean blood loss was(40.1?10.2)ml(8-50 ml).After the surgery,2 patients developed uterine perforation,3 had hyponatremia,and 5 showed transient fever.Among the patients,160(95.2%)were satisfied with the outcomes of the surgery.Conclusions Transcervical electro-resection by hysteroscopy is a minimally invasive,safe,and effective method for submucous uterine myoma.Preoperative preparation,strict indication criteria,and intraoperative monitor are three key points to avoid operation-related complications.

Objective To examine the validity and reliability of the abbreviated mental test (AMT) among Chinese subjects. Methods Two groups of subjects participated in the study. One group consisted of 38 patients with neurological disorders and the other 30 normal subjects (control group). They were assessed twice with AMT and mini mental state examination (MMSE) within one week. Results AMT was significantly correlated with MMSE as far as the total score and item scores were concerned( r =0.706～0.833).There were moderate to high correlation in all the items of AMT between the two assessment tools(ICC=0.810～0.996). The AMT scores in the patient group were significantly lower than that in the control group (7.60?2.55 vs 9.64?0.81, P

Objective To observe the effect of humanistic nursing care in rehabilitation ward.Methods 440 inpatients in rehabilitation ward were randomly divided into the observation group(228 cases,treated with humanistic nursing)and control group(212 cases,treated with traditional nursing).40 cases in each group received the investigation of patients' satisfaction to the service.Results The satisfactory rate of the patients in the control group to the attitude of the service,the nursing skill and health education missionary were 72.5%,75% and 67.5% respectively,but that of the patients in the observation group were all 100%,there was a significant difference between two groups(P<0.01).Conclusion Humanistic nursing care in rehabilitation ward can improve nursing qualification and increase patients' satisfactory rate.

OBJECTIVE:To observe the efficacy and safety of Guizhi fuling capsule combined with mifepristone in treatment of uterine fibroids. METHODS:116 patients with uterine fibroids were randomly divided into control group and observation group. Control group was orally given Mifepristone tablet 25 mg,2 h before meal in the first day of menstrual period,once a day,for con-tinuous 10 d;observation group was additionally given Guizhi fuling capsule 3 pills in non-menstrual period,3 times a day. 3 months was regarded as a treatment course,it lasted 2 courses. Clinical efficacy,and E2,FSH,SHBG,uterine volume,menstrual blood volume,uterine fibroid volume and incidence of adverse reactions in 2 groups before and after treatment were observed. RE-SULTS:Total effective rate in observation group was significantly higher than control group,the difference was statistically signifi-cant(P<0.05). After treatment,the FSH,E2,uterine volume,menstrual blood volume and uterine fibroid volume in 2 groups were significantly lower than before,and observation group was lower than control group,the differences were statistically signifi-cant(P<0.05);but there were no significant difference in the SHBG and adverse reactions between 2 groups(P>0.05). CONCLU-SIONS:The clinical efficacy of Guizhi fuling capsule combined with mifepristone in treatment of uterine fibroids is more signifi-cant than mifepristone alone,with good safety.
