Objective To understand the positive screening results and the infection characteristics of high-risk human papillomavirus (HPV) in Huaiji County,Guangdong Province,in the two years of the free standardization testing for rural women's “two cancers”. Methods The cervical cancer screening results of 35~64 year-old women with rural household registration who volunteered to participate in the “two cancers” free testing for rural women in the region were analyzed. High-risk HPV testing was used as the primary screening method for cervical cancer. The results of HPV16 and 18 positive patients were directly referred to colposcopy. If other high-risk HPV was positive,thin-layer cervical fluid-based cytology(TCT) was perform on those patients,whose TCT result severer than atypical squamous cells of undetermined significance (ASC-US) were referred to colposcopy,and those with suspicious or abnormal colposcopy results were referred to histopathological examination. Results The total positive detection rate of high-risk HPV was 9.35%. The positive rates of HPV16,18 and other high-risk HPV were 0.70%,0.32% and 7.72% respectively,mixed infection rate was 0.61%. The age group with the highest overall positive rate of high-risk HPV is 60-64 years old,and the rate is 11.22%. The referral rate for cytology was 65.63%,and the referral rate for colposcopy was 61.23%. The positive rate of cervical precancerous lesions was 323.03/100 000,the positive rate of cervical cancer was 45.5/100 000,and the early diagnosis rate was 87.64%.HPV16,18 and HPV mixed infections of cervical precancerous lesions and cervical cancer accounted for 70.79%.Conclusions The positive rate of high-risk HPV,cervical precancerous lesions and cervical cancer positive rate were high in this area. The being referred rate of cytology and colposcopy in cervical cancer screening was low,suggesting that there was a higher incidence of cervical cancer in this area risk.

目的 探讨实时超声弹性成像技术联合常规超声检查在评估脑卒中患者颈动脉粥样硬化斑块稳定性中的临床应用价值。方法 收集我院收治的临床确诊脑卒中患者(卒中组)34例作为研究对象,另抽取同期存在颈动脉斑块但未发生过脑卒中的人群(对照组)56例作为对照研究对象,进行超声弹性成像检测,并对检查结果进行统计分析。结果 34例脑卒中患者发现颈动脉粥样硬化斑块57个,其中低回声斑块29个,混合回声斑块21个,强回声斑块7个;56例对照组患者发现颈动脉粥样硬化斑块75个,其中低回声斑块22个,混合回声斑块25个,强回声斑块28个;两组间比较斑块数量之间、斑块大小之间差异有统计学意义(P<0.05)。颈动脉粥样硬化低回声、混合回声及强回声斑块弹性评分依次升高,其斑块硬度值依次升高;两组间斑块的评分数量分布差异有统计学意义(P<0.05);对于同一类型斑块的硬度值两组间差异无统计学意义(P>0.05);脑卒中组不同类型斑块间的硬度值差异有统计学意义(P<0.05)。结论 超声弹性成像技术可对脑卒中患者颈动脉粥样硬化斑块的稳定性进行半定量评估,不同类型斑块因所含组织成分的不同其弹性应变率表现也不同,能有效补充常规超声检查的信息的不足,进而评估斑块的稳定性。

Objective To explore the clinical value of real-time ultrasound elastography combined with conventional ultrasound in assessing the stability of carotid atherosclerotic plaques in stroke patients. Methods Thirty-four patients with clinically confirmed stroke (stroke group) in our hospital were collected as the research object. Another 56 patients with carotid plaque but without stroke (control group) in the same period were selected as the control object for ultrasonic elastography detection, and the results were analyzed statistically. Results Thirty-four stroke patients were found 57 carotid atherosclerotic plaques, including 29 hypoechoic plaques, 21 mixed echoic plaques and 7 hyperechoic plaques; 56 control patients were found 75 carotid atherosclerotic plaques, including 22 hypoechoic plaques, 25 mixed echoic plaques and 28 hyperechoic plaques. There were significant differences between the number of plaques and the size of plaques (P<0.05). Carotid atherosclerosis low echo, mixed echo and strong echo plaque elasticity score increased in turn, the plaque hardness value increased in turn; the number of plaque scores between the two groups had statistical significance (P<0.05); for the same type of plaque hardness value between the two groups had no significant difference (P>0.05); There were significant differences in hardness values between the same types of plaques (P<0.05). Conclusion Ultrasound elastography may semi-quantitatively evaluate the stability of carotid atherosclerotic plaques in stroke patients. Different types of plaques have different elastic strain rates because of different tissue components. It may effectively complement the information deficiency of conventional ultrasound examination, and then evaluate the stability of plaques.

Objective To explore the value of ultrasound combined with different methods in improving the detection rate of patent foramen ovale. Methods 88 cases of clinically suspected patent foramen ovale in our hospital were collected as the research objects to carry out the ultrasonic image group examination (routine transthoracic echocardiography TTE, transesophageal echocardiography TEE, right heart contrast echocardiography), and the results of multiple groups of ultrasonic image examination were recorded for retrospective statistical analysis. Results Among 88 subjects, 12 (13.6%) were found to have PFO (+)by conventional transthoracic echocardiography, 2 of them had atrial septal aneurysm. 20 cases (90.9%) of PFO were found by transesophageal ultrasonography, and two of them were from pulmonary arteriovenous fistula.In all the subjects, 39 cases (44.3%) of PFO were found by right heart sonography, 24 cases were found in resting state, 39 cases were found after Valsalva operation, 4 cases were found with aneurysm of atrial septum, 3 cases with pulmonary arteriovenous fistula (one of them was from pulmonary vein). Among the 14 patients examined by transesophageal ultrasound combined with right cardiac sonography, 10 (71.4%) were found to have PFO(+). According to the number of microbubbles, the right echocardiography showed that there were 16 cases in grade I, 5 cases in grade II, 18 cases in grade III, and there were statistical differences in the semi quantitative classification of RLS in different states (χ²=12.729, P=0.02). Conclusion Ultrasound image histology can be used for semi quantitative evaluation of patients with patent foramen ovale, which can effectively supplement the lack of single conventional ultrasound information, and provide objective basis for clinical diagnosis and treatment.

Objective To investigate the effect of cytotoxin-1 (CTX-1)on the proliferation and apoptosis of ovarian cancer SKOV-3 cells. Methods SKOV-3 cells were treated with CTX-1 at concentrations of 0, 4, 8, 12 μg/mL for 6, 12, and 24 hours respectively. Cell viability was measured by MTS method. SKOV-3 cells were treated with 8 μg/mL CTX-1 for 24 and 48 hours, by Hoechst-33258 fluorescence staining to observe the morphology of nuclear chromatin. The apoptotic rate of SKOV-3 cells was detected by flow cytometry after 6 and 12 hours of treatment. Results CTX-1 at 4, 8, and 12 μg/mL inhibited the activity and proliferation of SKOV-3 cells in a time-dose-dependent manner. Hoechst-33258 staining observation showed that the apoptotic cell chromatin was condensed or fragmented chromatin, the chromatin was unevenly colored, and the nuclear morphology was different. It became more obvious with time. 8 μg/mL CTX-1 treated cells, the 6 h cell necrosis rate was (1.90±0.27)%, the late apoptosis rate was (10.96±1.56)%, and the early apoptosis rate was (1.52±0.39)%; 12 hours cell necrosis rate was (10.62±0.96)%, late apoptosis rate was (15.07±1.23)%, and early apoptosis rate was (1.88±0.17)%, compared with the control group, the difference was statistically significant (P<0.01). Conclusion CTX-1 may inhibit the activity of human ovarian cancer cells, inhibit its proliferation in vitro, and induce its apoptosis. The effect is dose-dependent and time-dependent. Mainly it causes late apoptosis and necrosis of cells.
