Objective To detect circulating antigen (Cag) for diagnosing neurocysticercosis. Method ELISA was performed with monoclonal antibody 4B6 against the cyst fluid antigen of Cyticercus cellulosae for detecting Cag in serum and/or cerebrospinal fluid (CSF) of patients with neurocysticercosis or with other diseases. Results In the group of 82 cases of neurocysticercosis, the positive rate of serum Cag was 79.2% (65/82) and the positive rate of CSF Cag was 100% (26/26). After chemotherapy for 20 cases with positive serum Cag, the titer of serum Cag in 17 cases dropped to zero(85% ). Cag could not be detected in specimens from patients with other diseases. Conclusion These results indicate that the determination of Cag, especially of the CSF Cag, is useful for the diagnosis of neurocysticercosis and the drop in serum Cag is a good parameter for the evaluation of the effectiveness of chemotherapy.

Objective To investigate the application value of identification of the scalp surface locations of cerebral ischemia lesions before direct revascularization for moyamoya disease and to design surgical approaches according to this by using the fusion of single photon emission computed tomography ( SPECT) cerebral perfusion imaging with CT imaging. Methods The clinical data of 13 adult patients with ischemic-type moyamoya disease underwent superficial temporal artery-middle cerebral artery bypass surgery were analyzed retrospectively. SPECT cerebral perfusion imaging was fused with CT imaging of the same machine before procedure. The lesions of ischemia were located on the cortical surface. The surgical approaches were designed at the center of the ischemic lesions. The patients were followed up for 6 to 12 months after procedure. The improvement of clinical symptoms and cerebral perfusion of the patients were observed after operation. Results One patient had perioperative cerebral hyperperfusion syndrome,and the others did not have any perioperative complications. At one-month follow-up, the improvement of symptoms in 4 patients were excellent,in 5 were good,in 4 were fair,and none was poor. At 6 to 12 month follow-up,the improvement of symptoms in 9 patients were excellent,in 4 were good,and none was poor. The postoperative visual SPECT cerebral perfusion imaging analysis suggested that the cerebral perfusion was improved significantly as compared with before procedure in all patients. Quantitative analysis:There was significant difference in target ischemic lesions between preoperative Fb and postoperative Fb ([2. 13±1. 06]% vs. [4. 13±2. 09]%;P<0. 05). There was significant difference between preoperative Fb and Fe ([2. 46±1. 97]% vs. [2. 13±1. 06]%;P<0. 05). The postoperative BFCR was [67. 57±3. 78]%( >50%) , which indicated that the efficacy of the procedure was remarkable. The superficial temporal arteries fed to brain of the patients were observed after procedure by using the head CT angiography. The postoperative head MRI reexamination showed no new infarcts occurred at 6 months. Conclusion Combine SPECT cerebral perfusion imaging with CT imaging to design surgical approach for superficial temporal artery-middle cerebral artery bypass surgery may improve the efficacy and reduce the risks of operation.

Objective:To investigate the therapeutic clinical effect of laparoscopic high uterosacral ligament suspension (LHUS) combined with cervical amputation and vaginal sacrospinal ligament fixation (SSLF) in the treatment of prolapse of uterus in childbearing period.Methods:From October 2011 to December 2016, the clinical data of 78 patients with uterine prolapse above grade Ⅱ treated in Department of Gynecology, Jizhong Energy Fengfeng Group Hospital were retrospectively analyzed.According to different surgical methods, the patients were divided into LHUS group (40 cases) and SSLF group (38 cases). The operation time, intraoperative bleeding volume and hospital stay of the two groups were compared by independent sample t test.Before and 6 months after the operation, the prolapse quality of life questionnaire (P-QOL), pelvic organ prolapse/incontinence sexual function questionnaire-12 (PISQ-12) and pelvic floor distress inventory-short form 20 (PISQ-20) were used.PFDI-20 and pelvic floor impact questionnaire-short 7 (PFIQ-7) were used to evaluate patients′ quality of life, sexual function and pelvic floor function.Paired t test was used to compare the above scores before and 6 months after operation in the same group.Results:There were no significant differences in operation time, intraoperative bleeding volume and hospital stay between the two groups ( t value were 1.593, 1.203 and 0.535, , respectively, all P>0.05). The preoperative P-QOL, PISQ-12, PFDI-20, and PFIQ-7 scores of patients in the LHUS group were (55.4±11.1), (25.1±4.6), (15.0±4.9), (8.9±2.8) points, and (53.7±10.5), (23.9±3.7), (14.1±4.2), (9.2±3.0) in the SSLF group.There was no statistically significant difference in the indexes between the two groups before operation (t value were 0.694, 1.265, 0.869 and 0.457, respectively, all P>0.05). The scores of P-QOL, PISQ-12 at 6 months after operation in LHUS group((87.9±12.0), (39.1±6.1)) and SSLF group((81.3±11.7), (35.6±4.0)) were significantly higher than those before operation( t value were 12.574, 11.589, 10.823 and 13.236, respectively, all P<0.001). The scores of P-QOL and PISQ-12 at 6 months after operation in the two groups were higher than those before operation((87.9±12.0), (39.1±6.1)), and the P-QOL score of LHUS group was higher than that of SSLF group 6 months after operation, the difference was statistically significant ( t value were 12.574, 11.589, 10.823 and 13.236, respectively, all P<0.001). At 6 months after operation, PFDI-20 and PFIQ-7 scores in LHUS group((2.1±0.3), (1.3±0.2) points) were significantly lower than before operation ( t value were=16.619 and, 17.123, all P<0.001). The PFDI-20 and PFIQ-7 scores in LIHUS group were lower than those in SSLF group((2.7±0.3), (1.9±0.2)) at 6 months after operation (t values were 10.096 and 13.073, respectively, all P<0.001). Conclusion:LHUS combined with cervical resection in the treatment of prolapsed uterine prolapse can effectively improve the quality of life, sexual function, and pelvic floor function.The effect is better than SSLF, which is worthy of clinical promotion.
