X-ray is usually used to determine anatomy and localization during conventional permanent pacemaker implantation.But X-ray exposure might induce radiation injury to fetus.In this paper,we reported 2 cases successful double cavity permanent pacemaker implantation in pregnant women woman at 13 weeks of gestation under the guidance of transthoracic echocardiography.The postoperative pacing parameters were good,the whole process was finished with zero radiation,and there were complications during pregnancy.Both cases resulted in full-term pregnancies and the natural delivery of healthy newborns.Pacemaker electrodes were in normal position as confirmed by post-delivery X-ray examinations.

Standardization is the universal language of the world, and standardization of traditional Chinese medicine (TCM) is essential for its communication in China and globally. However, the principles and methods of TCM acupuncture standardization have been unclear and inadequate in the early stages. Based on an investigative approach to understanding the current status, identifying problems, and finding solutions, our team has established basic principles of TCM acupuncture that embody Chinese wisdom, evaluated the international strategic environment systematically, proposed the principle of “importance of harmony and exercise of impartiality”, and established basic working principles. A series of methods for TCM acupuncture standard development and evaluation have been constructed, including general standards for the revision of TCM acupuncture standards, the first TCM acupuncture clinical research management specification, a shared full chain technology platform, a data center, and an evaluation research base for TCM acupuncture clinical research. Evaluation criteria for ancient literature and expert experience, a recommendation method for the “three main and three auxiliaries” TCM guideline for prevention were established, and quantifiable assessment methods of TCM standard applicability were proposed. These findings provide methodological guidance for TCM acupuncture standardization.

OBJECTIVETo identify factors that predictive of quality of life after microsurgical removal of petroclival meningiomas.

METHODSA consecutive series of 71 cases of petroclival meningiomas received microsurgical removal between July 1991 and April 2010 were analyzed retrospectively. Quality of life was measured using Karnofsky performance scale (KPS). Complete pre-operative, post-operative and follow-up data were obtained from all 71 patients including 18 male and 53 female patients with the mean age of (47 ± 11) years (aging from 15 to 68 years). The duration between onset of symptoms and diagnosis ranged from 1 week to 180 months with the mean duration of (32 ± 30) months. And the tumor size was 15-72 mm with the average of (44 ± 11) mm. Main presentations included headache, unsteady gait, hemiparesis, dysphagia, hoarseness, facial numbness or pain, Bell's palsy, hearing impairment etc. The preoperative KPS was 40-100 with the average of 69 ± 11. The retrosigmoid (-transtentorial) approach was performed in most cases (91.5%). Intergroup χ² test and logistic regression analysis were conducted for prognostic factor characterization.

RESULTSThe gross total resection (all were Simpson gradeII) reached in 48 cases (67.6%) and 1 case died postoperatively. The main new neurological dysfunctions were cranial nerve paralysis and hemiplegia with the postoperative KPS of 20-100 with the average of 73 ± 16.Sixty-four cases were followed for 4-132 months with the average of (61 ± 48) months. Seven patients died during follow-up, tumor recurrence and progression were identified in 6 and 8 cases, respectively. The KPS at the last visit ranged from 50 to 100 with the average of 83 ± 13. The extent of tumor resection (OR = 0.280, 95% CI: 0.081-0.967, P = 0.044), preoperative brainstem edema (OR = 0.100, 95% CI: 0.027-0.372, P = 0.001), relationships between tumor and neurovascular structures (OR = 0.288, 95% CI: 0.084-0.985, P = 0.047) and depth of invasion into cavernous sinus (OR = 0.254, 95% CI: 0.061-1.057, P = 0.048) had significant correlations with the prognostic quality of life.

CONCLUSIONSWith regard of the choice of surgical approaches, the extent of tumor resection, the protection of neurovascular structures surrounding the tumor and the management of perioperative period, the therapeutic strategies for each patient should be customized to achieve better prognosis.
