目的探讨子宫输卯管造影术（HSG）在诊治宫腔粘连（IUA）中的价值。方法回顾性分析本院2007年3月～2011年4月经HSG诊断为宫腔粘连的200例患者的临床资料。结果经HSG诊断,宫腔完全性粘连22例（11．0％）,中央型粘连34例（17．0％）,周围型粘连69例（34．5％）,混合性粘连75例（37．5％）。经官腔镜检查,HSG与宫腔镜诊断符合率为91．0％,误诊率为9．0％。结论HSG可以确定粘连的部位和范围、程度,且操作简单、方便,患者痛苦较少,是诊断宫腔粘连常规、可靠的检查手段。     

不同疾病状态下新生儿脑组织氧合变化的对照研究

目的采用近红外光谱测定技术（NIRS）检测新生儿脑组织氧饱和度（rSO2）,探讨不同疾病状态下新生儿脑rSO2的变化规律,为临床应用提供依据。方法2007年4月至2008年10月以无特殊疾病的223名足月儿作为正常组足月儿亚组,于生后3d内测定脑rSO2;以196例患有可能影响脑氧合疾病的新生儿作为疾病组,在疾病急性期测定脑rSO2。疾病组分为呼吸系统疾病亚组（97例）,分析脑rSO2与PaO2的关系;循环系统疾病亚组（44例）,分析脑rSO2与心率的关系;脑损伤亚组（55例）,分析脑rSO2与脑血流的关系。结果①疾病组脑rSO2为（56±6）%,显著低于正常组足月儿亚组（P〈0.05）。②轻度与重度呼吸系统疾病亚组脑rSO2分别为（60±3）%和（54±6）%,轻度和重度循环系统疾病亚组脑rSO2分别为（59±3）%和（53±6）%,轻度和重度脑损伤亚组脑rSO2分别为（59±3）%和（54±4）%。3个疾病亚组中轻度与重度间脑rSO2差异均有统计学意义（P〈0.01）。③呼吸系统疾病亚组脑rSO2与PaO2呈三次方程曲线（y=-62.93＋4.75x-0.059x2＋0.00024x3）。PaO2≥60mmHg时,脑rSO2约为62%,脑氧合正常;PaO2〈50mmHg时,脑rSO2〈57%,脑组织缺氧。循环系统疾病亚组脑rSO2与心率呈二次方程曲线（y=1.11＋0.8241x-0.0027x2）。心率在105～200.min-1时,脑rSO2〉58%,脑氧合正常;心率低于105.min-1或高于200.min-1时,脑rSO2〈58%,脑组织缺氧。脑损伤亚组脑rSO2〈58%时,大脑前动脉血流平均速度代偿性增高,阻力指数偏低,脑损伤较重。结论严重疾病状态下可同时伴有脑组织缺氧。脑rSO2的变化与PaO2、心率及脑血流的变化密切相关。NIRS技术为临床提供了一种可靠的、有价值的脑氧合检测方法,有助于临床直观量化地发现脑组织的缺氧。     

Knowledge of Cervical Cancer Among 25–54-Year-Old Women in Beijing

The purpose of this study is to examine knowledge of cervical cancer and the relationship between knowledge of human papillomavirus (HPV) infection and cervical disease in a largely representative Beijing population. A questionnaire-based survey was conducted in a Beijing population sample of married women ages 25 to 54 years (n = 6,339), evaluating knowledge and relevant factors with regard to cervical cancer. Knowledge levels were low; only 52.5% (n = 3,328) of the respondents knew that cervical cancer can be detected in its early stage. Only 26.9% reported that human HPV infections were risk factors for cervical cancer. The level of knowledge was lower among older, with less education, less income, unstable profession, and non-Beijing Hukou women (all P < 0.01). An increasing level of knowledge may impact positively on intentions to participate in cervical cancer screening. Education schemes to improve knowledge of cervical cancer should be performed in a multimodel, multichannel method.

Rapid Method for Multi-residue Determination of Avermectins in Bovine Liver Using High-performance Liquid Chromatography with Fluorescence Detection

A simple method using high-performance liquid chromatography and fluorescence detection is presented for the simultaneous determination of the antiparasitic agents avermectins (abamectin, ivermectin and doramectin) in bovine liver. Samples were extracted using acetonitrile and cleaned up on an alumina SPE column and derivatized with trifluoroacetic anhydride. The derivatives were detected using fluorescence detector set at 365 nm excitation and 475 nm emission wavelengths. As the results, the limit of quantification for three avermectins was about 1 μg/kg. Inter-assay showed the mean recoveries of avermectins in bovine liver ranged from 72% to 81%, with RSD less than 9.9%.     

The LNG-IUS study on adenomyosis: a 3-year follow-up study on the efficacy and side effects of the use of levonorgestrel intrauterine system for the treatment of dysmenorrhea associated with adenomyosis

Background

The objective of this study was to evaluate the efficacy and side effects of the levonorgestrel-releasing intrauterine system (LNG-IUS) in the treatment of moderate or severe dysmenorrhea associated with adenomyosis for a 3-year follow-up period.

Study Design

The LNG-IUS was inserted into 94 women who had moderate or severe dysmenorrhea associated with adenomyosis diagnosed by transvaginal sonography during Cycle Days 5-7. A visual analogue scale (VAS) of dysmenorrhea, uterine volume and serum CA125 levels were used to assess the efficacy of the treatment at baseline and 3, 6, 12, 24 and 36 months after the LNG-IUS insertion. Side effects were recorded at every follow-up visit.

Results

The VAS of dysmenorrhea dropped continuously and significantly from the baseline score of 77.9±14.7 to 11.8±17.9 after 36 months of the LNG-IUS insertion (p<.001). The uterine volume decreased significantly from 113.8±46.9 mL to 94.5±40.1 mL (p=.003) at 6 months and to 87.7±35.8 mL (p<.001) at 12 months and then rose slightly, but the variables at 24 and 36 months still decreased significantly in comparison with the baseline variable (p<.001). The serum CA125 levels reduced significantly starting from 6 months after device insertion (p<.001). The most common side effects were weight gain (28.7%), simple ovarian cyst formation (22.3%) and lower abdominal pain (12.8%). At 36 months, the overall satisfaction rate of the treatment was 72.5%.

Conclusions

The LNG-IUS appears to be an effective method in alleviating dysmenorrhea associated with adenomyosis during 3 years. It may be a valuable long-term alternative for the treatment of adenomyosis.
