RESUMO
Objective:To investigate the level of serum vascular endothelial growth factor (VEGF) and its correlation with clinical symptoms in patients with first-episode drug-naive schizophrenia patients of different genders.Methods:From January 2016 to October 2019, a total of 81 first-episode drug-naive schizophrenia patients(patient group, 41 male, 40 female) and 64 healthy controls (control group, 40 male, 24 female) were included in this study.The serum level of VEGF was detected with flow cytometric bear array (CBA). Positive and negative symptom scale (PANSS) was used to evaluate the relevant clinical symptoms of patients.SPSS 22.0 software was used for statistical analysis.Independent sample t-test and nonparametric test were used for comparison between groups.The relationship between VEGF and clinical variables was analyzed by Pearson correlation analysis and Spearman correlation analysis. Results:The level of serum VEGF in the patient group was significantly lower than that in the control group(148.08(75.89, 208.61)pg/mL, 179.94(99.14, 318.41)pg/mL, Z=-2.20, P=0.028). The total PANSS score((82.71±17.30), (73.45±16.36), t=2.473, P=0.016)and cognitive score((7.88±3.36), (6.23±2.81), t=2.402, P=0.019) in male patients were higher than those in female patients.There was a negative correlation between VEGF level and PANSS negative symptom score in the patient group( r=-0.228, P=0.041), as well as significant negtive correlation between VEGF level and cognitive score in male patients( r=-0.425, P=0.007). Conclusion:The level of serum VEGF is reduced in first-episode patients with schizophrenia, which influences their negative symptom. Moreover, the decline in serum VEGF level is implicated in cognitive impairments in male patients with first-episode schizophrenia.
RESUMO
Objective:To evaluate the safety and efficacy of endovascular interventional treatment of the intracranial vertebrobasilar trunk large aneurysms (VBTLAs) compared with conservative treatment.Methods:This is a prospective multi-center cohort study. From October 2012 to October 2018, a total of 69 patients with intracranial vertebrobasilar trunk large aneurysm (diameter>10 mm) from Henan Province People's Hospital and People's Liberation Army Rocket Medical Center were included in this study. Patients themselves chose either endovascular interventional therapy (interventional group) or conservative treatment (conservative group) after discussion with their doctors. The χ 2 test was used to compare the incidence of deaths, stroke, and all other serious adverse events including other site bleeding, myocardial infarction and others between the two groups. Results:A total of 69 patients were enrolled, of whom 51 patients were enrolled in interventional group, 18 patients underwent endovascular reconstructive therapy, 11 patients underwent deconstructive therapy, and 4 patients underwent conjunction interventional treatments. Eighteen patients were enrolled in conservative group, of whom 11 cases received simple risk factor control, 7 cases received antiplatelet and risk factors control. The proportions of hypertensive patients 94.4% (17/18) and giant aneurysms 50.0% (9/18) in the conservative group were higher than those in the surgery group 64.7% (33/51, χ 2=4.500, P=0.034), 19.6% (10/51, χ 2=4.730, P= 0.030).The incidence of all serious adverse events associated with protocol was 15.7% (8/51) in the interventional group and 44.4% (8/18) in the conservative group [risk ratio (RR) =0.353, 95% confidence intervals (CI): 0.156-0.801], and the difference was significant (χ 2=4.668, P=0.031). The incidence of fatal events associated with protocol was 2.0% (1/51) in the interventional group and 38.9% (7/18) in the conservative group (RR=0.050, 95%CI: 0.007-0.382), and the difference was significant (χ 2=14.281, P<0.001). The incidence of hemorrhage events associated with protocol was 2.0% (1/51) in the interventional group and 22.2% (4/18) in the conservative group (RR=0.088, 95%CI: 0.011-0.738), and the difference was significant (χ 2 =5.391, P=0.020). Follow-up imaging showed that the occlusion rate of aneurysms in 44 patients in the interventional group was 56.8% (25/44) after a median follow-up of 6 months. Imaging follow-up was obtained in 9 patients, whose occlusion rate of aneurysms was 0 and the median follow-up time was 12 months, in the conservative group. The difference was significant(χ 2 =7.534, P=0.006). Conclusion:Compared with conservative treatment, endovascular intervention of the intracranial VBTLAs has lower incidences of serious adverse events and death events.
RESUMO
Objective@#To evaluate the actual efficacy of cervical cancer and precancerous lesions screening approaches in real-world regions with different economic levels in China.@*Methods@#The demonstrative application and effect evaluation of cervical cancer screening program were conducted in 21 hospitals nationwide from 2015 to 2018. Multi-stage sampling method was adopted to divide the country into 7 large areas according to geographical location. Two to four screening sites of two types of cancer (cervical cancer and breast cancer) were selected in each area, and the grassroots screening sites were implemented under the guidance of superior hospitals. In rural areas, women were initially screened using cytology, human papillomavirus (HPV) testing and visual inspection. The women with positive cytology or visual inspection were referred for colposcopy, and the women with positive HPV infection were randomly referred for reflex cytology or visual inspection, or direct colposcopy examination. In urban areas, women were primarily randomized into cytology or HPV testing groups. The women with abnormal cytology or positive HPV 16/18 infection were directly referred for colposcopy examination, whereas the women with positive infection of the other 12 high-risk subtypes of HPV were referred for reflex cytology or colposcopy. All of recruited women would be follow-up and screened by the baseline screening techniques in the third year while the positive women underwent colposcopy examination. The positive rates, referral rates, the detection rates of grade 2 and above of cervical intraepithelial neoplasia (CIN 2+ ) were compared.@*Results@#A total of 63 931 women were recruited at the baseline. Among them, 11 rural sites included 33 823 women: 15 577, 11 157 and 7 089 women were screened by HPV testing, visual inspection via acetic acid or Lugol′s iodine (VIA/VILI) and cytology, respectively. Additionally, 30 108 women were from 10 urban sites: 9 907 and 20 201 women were screened by cytology and HPV subtyping, respectively. The HPV positive rate for urban women was 9.34%, whereas that for rural women was 12.53%. The abnormal rate of cytology for urban women was 5.63%, and that for rural women was 4.24%. The positive rate of VIA/VILI in the rural women was 12.25% Furthermore, the detection rate of CIN2+ at the baseline was 0.56%, and that was statistically higher in HPV-positive group than cytology-positive group (P<0.05).@*Conclusions@#All of screening sites completed the baseline screening tasks as expected. The prevalence of HPV infection is higher in rural women than urban women. The performance of HPV testing is better than cytology for detecting CIN2+ cases. This real-world demonstration study provides evidences for cervical cancer prevention and control in different regions.
