Eighteen male patients and 10 female patients with Bt.Behccedil;et's disease were addressed to study the influences of sex factor on Behccedil;et's disease. It was found that recurrences of uveitis were more frequent in malepatients than in females,and that male patients were worse than females in prognosis due to the high severity of retinal vasculitis and the low sensitivity to treatment.It is pressumed that the sex hormone may, at least in part,contribute to the diffrenees between the male and female patients. （Chin J Ocul Fundus Dis,1994,10:143-145）
ObjectiveTo investigate the effect of sex on learning and memory ability of newborn mice with hypoxic-ischemic brain injury.MethodsFifty C57BL/6 mice aged 10 days were divided into hypoxia-ischemia group and sham group according to the random number table method, and there were 28 in the hypoxic-ischemic group and 22 in the sham group with half female and half male respectively. In the ischemia-hypoxia group, the left common carotid artery was ligated and then the mice were placed in 34℃ hypoxia chambers with 8% oxygen and 92% nitrogen mixture for 45 minutes. In the sham group, only the skin of the left neck was cut and sutured. After 2 months, Y maze test and Morris water maze test were used to evaluate the learning and memory ability of mice.ResultsThe success rate of the hypoxic-ischemic group was 71.4% (20/28), and that of the sham group was 100.0% (22/22), a total of 42 mice were enrolled in the experiment. In Y maze test, there were differences in entries and total distance of new arms between the two groups (entries: F=16.068, P<0.001; total distance: F=8.532, P=0.007); compared between different groups in the same gender, the entries and total distance of new arms in the hypoxic-ischemic group were lower than those in the sham group with statistically significant differences (entries in males: P=0.001, entries in females: P=0.012; total distance in males: P=0.010, total distance in females: P=0.046). Compared between males and females in the same group, the entries and total distance of new arms of females were higher than those of males in the hypoxic-ischemic group, with statistically significant differences (P=0.039, 0.043). In Morris water maze test, the escape latency of positioning navigation in the hypoxic-ischemic group was higher than that in the sham group, and males showed more obviously poor performance (P<0.001); in the experiment of space exploration, differences were found in the duration of stay and the target quadrant entries between the two groups (duration of stay: F=8.297, P<0.001; entries: F=4.042, P=0.014), and there were statistically significant differences in the same gender males and females in the hypoxic-ischemic group and the sham group (duration of stay in males: P=0.003, duration of stay in females: P=0.038; entries in males: P=0.006, entries in females: P=0.041). Compared between males and females in the same group, the duration of stay and the target quadrant entries of females were higher than those of males in the hypoxic-ischemic group, with statistically significant differences (duration of stay: P=0.018; entries: P=0.032).ConclusionsThe learning and memory ability of newborn mice may be slightly impaired after hypoxic ischemic brain injury. There is significant difference in the effect on learning and memory ability between different genders, and the effect on males is higher than that on females.
ObjectiveTo explore the correlation between coronary artery plaque composition and the gender via 128-slice spiral CT coronary angiography (128-SCTCA). MethodsBetween January and December 2012, 143 patients with coronary artery plaque diagnosed by 128-SCTCA were selected. The patients were divided into group A (no more than 50 years old, n=37) and group B (over 50 years old, n=106). ResultsThere were 29 male patients in group A, with 70 plaques including 30 fibrous plaques, 17 mixed plaques, 11 soft plaques, 12 calcified plaques; and the other 8 female patients had 13 plaques including 7 fibrous plaques, 2 mixed plaques, 2 soft plaques, and 2 calcified plaques. In group B, 56 male patients had 116 plaques, including 48 mixed plaques, 40 fibrous plaques, 14 soft plaques and 14 calcified plaques; the other 50 female patients had 90 plaques, including 36 mixed plaques, 22 fibrous plaques, and 16 soft plaques and calcified plaques. The differences of the plaque composition between males and females were not significant both in group A (χ2=0.664, P>0.05) and group B (χ2=3.708, P>0.05). ConclusionThere is no obvious correlation between gender and coronary plaque composition.
ObjectiveTo elucidate the relationship between clinical characteristics and pathology findings of solitary pulmonary nodules (SPN). MethodsA retrospective cohort study was carried out on 231 SPN patients pathologically confirmed between January 2009 and December 2013 in Nanjing General Hospital of Fuzhou Military Command and Fuzhou Second Hospital. Using pathological results as reference standard, the sex, age, smoking history, smoking amount, quit smoking history, and extrapulmonary malignant tumor history were compared between the SPN patients with different pathological type. ResultsFemale and age were positively correlated with the probability of malignancy in SPN with correlation coefficients as 1.090 and 0.063 respectively. Extrapulmonary malignant tumor history, smoking history, smoking amount, quit smoking history did not show significant relationship. Gender was a factor that affects pathological types of SPN. Female patients were in higher risk than male patients to have precancerous lesions, pulmonary aspergillosis, pulmonary sclerosing hemangioma, adenocarcinoma. Male patients had higher risk suffering from pulmonary tuberculosis, pulmonary cryptococcosis, squamous cell carcinoma, adenosquamous carcinoma, inflammatory pseudotumor and metastases. Distribution of SPN pathologic types in each age group was similar. Most patients who had precancerous lesions, pulmonary hamartoma, pulmonary aspergillosis, pulmonary sclerosing hemangioma, adenocarcinoma and inflammatory pseudotumor were not smokers. ConclusionsGender and age are valuable in distinguishing benign SPN from malignant SPN. Pathologic types of SPN are related to patients' gender and smoking history.
ObjectiveTo determine the retinal thickness of normal children 3-6 years old and its relationship with the age and gender. MethodsIn a cross-sectional study, 480 eyes of 240 normal preschool children including 115 male and 125 female, ages 3 to 6 years in the urban of Beijing, China were included. The average age was (4.93±0.77) years old. The visual acuity, slit-lamp microscopy and frequency domain optical coherence tomography (FD-OCT, Optvue, Inc. USA) were examined. The retinal thickness of the macular fovea and 500, 750, 1500 μm from temporal and nasal side around the fovea were measured. 32 eyes were excluded from the study because they couldn't cooperate. Pearson correlation analysis was used to determine the correlation between age and macular retinal thickness. Independent samples group t-test was used to compare the differences between boys and girls. ResultsThe mean thickness of macular fovea was (169.10±20.587) μm. The mean macular thickness of boys was significantly higher than girls (t=-4.549, -6.167, -5.492, -5.163, -6.749, -7.494, -6.874; P≤0.001). The mean thickness of 500 μm and 750 μm from nasal side of macular fovea were significantly higher than temporal side (t=5.594, 15.778, 7.678, 18.180; P < 0.001). There was no significant relevance between macular thickness and age. ConclusionsThe mean macular thickness of boys is significantly higher than girls in normal children in the urban of Beijing. There is no significant relevance between macular thickness and age.
Objective To explore the correlation between gender and long-term prognosis of patients with type-B acute aortic dissection (AAD) after endovascular therapy (EVT). Methods From January to December 2012, all patients with type-B AAD undergoing EVT were enrolled by retrospective and observational study. They were divided into male and female groups. Kaplan-Meier analysis was used to analyze the correlation between gender and the cumulative survival rate. Results A total of 131 tyep-B AAD patients who had undergone EVT were selected, including 97 males (74.0%), and 34 females (26.0%). The medium follow-up duration was 2.1 years. Smoking history, cholesterol, white blood cell count, hemoglobin, creatinine and uric acid of the patients in males were higher than those in females (P<0.05); while the difference in other indexes were not significant (P>0.05). The inhospital mortality of male patients was 10 (10.3%), and was 3 (8.8%) in female patients; there was no significant difference between the two groups (P=0.803). Kaplan-Meier analysis showed that there was no significant difference in cumulative survival rate between the two groups (84.5% vs. 82.4%; Logrank test χ2=0.023, P=0.880). Conclusion No correlation between gender and long-term prognosis in patients with type-B AAD after EVT is found.
Objective To explore the impact of gender difference in 90-day outcomes after mechanical thrombectomy for acute cerebral infarction. Methods A prospective registration, observational, and retrospective analysis study was carried out. Patients with acute cerebral infarction who were admitted to the Department of Neurology of the First Affiliated Hospital of Chengdu Medical College and the Department of Neurology of Nanjing First Hospital between June 2015 and June 2019 were collected. Patients were divided into two groups based on gender. The detailed demographic, laboratory examination, imaging examination and clinical data were collected. Then, the data were analyzed using univariate and multivariate logistic regression analyses. Results A total of 298 patients were included. Among them, there were 185 males and 113 females. The differences in age, smoking, atrial fibrillation, using antiplatelet drugs before stroke, TOAST classification, and involved cerebrovascular sites between the two groups were statistically significant (P<0.05), and there was no statistically significant difference in other baseline data between the two groups (P>0.05). The results of univariate logistic regression analysis showed that the rate of 90-day favourable outcome of female patients was lower than that of male patients [odds ratio (OR)=0.462, 95% confidence interval (CI) (0.275, 0.775), P=0.030]. The results of multivariate logistic regression analysis showed that, after adjusting for confounding factors, there was no independent correlation between gender and the 90-day favourable outcome of patients with acute cerebral infarction who underwent mechanical thrombectomy [OR=1.511, 95% CI (0.745, 3.066), P=0.253]. Conclusion The gender has no significant effect on the 90-day favourable outcome of acute cerebral infarction patients treated with mechanical thrombectomy.
The incidence of chronic kidney disease is increasing worldwide, which greatly increases the risk of end-stage renal disease. It is particularly important to find out the risk factors for the development and progression of chronic kidney disease. Whether gender is a risk factor for the progression of kidney disease remains controversial with inconsistent results in human cohort studies with diabetic or non-diabetic kidney disease. In most of the studies, women seem to exhibit certain gender advantages. Sex hormones, renal hemodynamics and lifestyle differences may play an important role. The underlying mechanism of gender affecting the progression of kidney disease deserves further exploration. This article reviews the gender differences and possible mechanisms in diabetic and non-diabetic chronic kidney disease, in order to provide reference for future research.
