Chinese Journal of Schistosomiasis Control 2014;(4):437-438,452
Objective To investigate the relationship between Toxoplasma gondii(TOX)infection and abnormal pregnancy outcomes. Methods A total of 126 cases of abnormal pregnancy women in the Department of Obstetrics and Gynecology,the Fourth People’s Hospital of Langfang from March to December 2013 were chosen as an experimental group,and 263 cases of normal pregnancy women of childbearing age as a control group. The TOX-IgM and-IgG antibodies were detected by ELISA. The data in the two groups were processed and analyzed by SPSS13.0. Results The positive rates of TOX-IgM,-IgG in 126 cases of abnormal pregnancy women were 7.94%and 19.84%respectively,and 1.90%and 8.75%in the control group respectively,and there were significant differences between them(χ2IgM=6.82,χ2IgG=9.70,both P<0.01). The positive rates of TOX-IgM,-IgG in the normal pregnancy women were lower than those in 4 sub-groups of abnormal pregnancy women,and all the differences were statistically significant(χ2spontaneous abortion = 10.40,χ2premature delivery = 9.03,χ2embryo damage =4.32,χ2birth defect = 4.04,all P<0.05). However,the TOX-IgM,-IgG positive rates in the 4 sub-groups of abnormal pregnancy women had no statistically signifi-cant difference(P > 0.05). Conclusions TOX infection could cause serious abnormal pregnancy outcomes. Therefore,the comprehensive control measures should be strengthened.

Objective To compare rotational DSA with routine DSA in the assessment of intracranial aneurysms. Methods Conventional anteroposterior, lateral and oblique views of DSA and rotational DSA were respectively performed in 20 patients suspected of intracranial aneurysms in subarachnoid hemorrhage using DSA (Philips Integris V 3000DSA system). Images were compared for localization of the aneurysm, shape of the aneurysmal neck and vascular branch anatomy. Results Among 20 patients, only 18 intracranial aueurysms were found by convertional DSA and the other two were only by the rotational DSA. Furthermore, conventional DSA examination could not clarify the relationships of 6 (6/18) aneruysms with their parent arteries and with the vascular branch anatomy including the aneurysmal neck could not be clarified in 7 (7/18) patients. However, shape of the aneurysms and visibility of the aneurysmal neck could be clarified after using the rotational DSA, and meanwhile, vascular anatomy can be indentified with the rotational DSA. Conclusion Rotational DSA often allows better visibility of vascular anatomy and aneurysmal neck compared with conventional DSA, offering more important information for operation.

Objective To study the variable orderliness of vocal fold vibration caused by the voice with different frequency in chest register of various healthy subjects having several age and sex through electroglottographic examination.Methods 120 healthy subjects were respectively evaluated with electroglottography, including the old group, the adult group, the men group and the female group. Meanwhile the parameters of vocal fold vibration, such as the contact quotient, the contact index, the contact quotient perturbation and the contact index perturbation were measured and analyzed.Results With increase of the frequency, the contact quotient was decreased in all subjects, having signification difference. The contact quotient of old group and adult group ,men and female group had also signification difference. But other parameters not represented the difference in statistics.Conclusion The closer degree of vocal fold was varied with the different frequency in chest register voice from the healthy subjects who were different in age and sex ,but the symmetry and regulation of vocal fold vibration were not related to age and sex. The results were help to study physiology of vocal fold.

Objection To study the effect of letrozole on EM rat models and influence on the reproductive system. Methods Surgically transplanted autologous uterine tissues to ectopic site beside the uterines in rats were used as animal models to study endometriosis. 20 EM model rats were random divided into letrozole-treated group and saline solution-treated control group. The change of ectopic lesion volume in each group was compared before and after treatment. Apoptotic cells were assessed by the terminal deoxynucleotidyl transferase-mediated deoxy-UTP nick-end labeling (TUNEL) assay, and the uterian horn and ovary were weighted and observed by optical microscopy to study the change of morphology. Results The volumes of the endometriotic tissues of letrozole group reduced more than that in control group[ ( 28. 75 ± 2.28 )mm3 vs ( 108.39 ±9. 98)mm3, P <0.01 ]. The apoptotic rate in letrozole group [ (5.52 ±2. 81 )% ]was higher than control group[ (2.11 ± 1.70)%, P <0. 01 ]. The ovarian weights in letrozole-treated group increased significantly[ (25.25 ± 9. 89) mg/100g vs ( 13. 10 ± 2. 70 ) mg/100g, P < 0. 01 ], arid the ovaries showed polycyst. The uterian weights in letrozole-treated group[ (41.46 ± 15.81 ) mg/100g vs (94. 81 ±18.00) mg/100g, P <0. 05 ] significantly decreased, and the endometriums presented atrophy. Conclusion Letrozole treated EM by means of increasing the apoptosis of the ectopic tissues. Letrozole would give ovarian over stimulating and the uterian weighting decreased as well as endometriums atrophy.

Objective To study transcerebellomedullary fissure approach to the fourth ventricle and the lateral brainstem without splitting vermis and depict its adjacent structure, and provide clinicians with anatomical information.Methods Five cadaveric heads fixed with formaldehyde and perfused with color latex in their arteries and veins were dissected with microsurgical anatomical skills. The composition of cerebellomedullary fissure and the distribution of the tela choroida, the inferior medullary velum and the posterior inferior cerebellar artery, and study anatomic base of this approach.Results Cerebellomedullary fissure is a natural anatomical gap which is located between the cerebellar tonsil, biventral lobule and medulla oblongata. The tela choroida and inferior medullary velum do not contain nerve tissue, and thus can be dissected to expose the fourth ventricle. The tonsil- medulla segment and telovelotonsillar segment of the posterior inferior cerebellar artery are the most important blood vessels of the cerebellomedullary fissure approach.Conclusions The transcerebellomedullary fissure approach can reach the fourth ventricle and dorsal brain stem through normal anatomic spaces without splitting the vermis, thus reducing the post-operative complications.
