Objective To investigate the situation of visual memory impairment in patients with myasthenia gravis (MG).Methods Thirty MG patients and 28 normal control subjects were tested with a battery of computerized tests (modified Smith working memory software), which was designed to assess visual-spatial and visual-object working memory.Results There was no significant difference in the accuracy rate of visual-object working memory test between the MG group and normal controls (MG group 73.4% ±9.7%, normal controls 72.7% ±8.5%).The accuracy rate of the visual-spatial working memory test in the MG group (76.6% ± 16.5%) was significantly lower than that in the normal controls (86.6% ±7.5%, Z = -2.204, P = 0.028).Conclusion The visual-spatial working memory is probably impaired while the visual-object working memory is relatively spared in MG patients.

Objective:To evaluate the surgical corrective results of maxillary hypoplasia in patients with cleft lip and palate withtranspalatal modified Le Fort Ⅰ osteotomy.Methods:In the study,1 1 patients (4 women,and 7 men)with maxillary hypoplasia secondary to cleft lip and palate underwent transpalatal modified Le Fort Ⅰ osteotomy at Peking University School of Stomatology from Jan.201 2 to Dec.201 3, with the mean age of 21 years (from 1 8 to 27 years),Bilateral sagittal split ramus osteotomy (BSSRO) and genioplasty were performed simultaneously in 9 of them for better appearance and functional occlu-sion.Lateral cephalometric radiographs were taken and traced before surgery,immediately after surgery and 6 months after surgery.The position of subspinale (A)on horizontal direction,the angle of sella-na-sion-subsipmale (SNA)and the angle of sella-nasion-supramental (SNB)were collected and analyzed to evaluate the results.Results:All the patients were uneventful with transpalatal modified Le Fort Ⅰosteotomy.All of them had a better profile and a satisfactory occlusionafter operation.The position of A was moved forward (6.6 ±1 .1 )mm on average in horizontal direction when surgery was completed,and maintained (6.0 ±1 .2)mm on average 6 months after surgery.The average of SNA was 75.9°±2.8° before surgery,81 .6°±8.6°immediately after surgery,and maintained 81 .0°±2.6°6 months after sur-gery.The average of SNB was 82.6°±3.7°before surgery,78.0°±2.4°immediately after surgery,and maintained 78.5°±2.4°6 months after surgery.Conclusion:The maxillary hypoplasia in cleft lip and palate patients can be successfully corrected with transpalatal modified Le Fort Ⅰ osteotomy and the func-tional occlusion can be achieved simultaneously.The effect of deformity correction was satisfactory. Transpalatal modified Le Fort Ⅰ osteotomy can move maxilla more sufficiently,especially applicable for the patient with severe palatal scars preoperatively.

Objective To explore the predicative value of transvaginal ultrasonography and 48 hours blood HCG ratio for ectopic pregnancy(EP).Methods A total of 90 patients in our hospital from June 2014 to May 2016 were selected as the object according to the pregnancy result and postoperative pathology (40 cases in EP group and 50 cases in control group).The endometrial thickness was measured through transvaginal ultrasonography while blood HCG was detected by chemiluminescence technique and 48 hours blood HCG ratio was calculated.To evaluate the individual and combined predicative value of endometrial thickness and 48 hours blood HCG ratio for EP,receiver operating characteristic curves(ROC) were generated and logistic regression analysis was conducted.Results The endometriam thickness and 48 h blood HCG ratio of EP group were (11.75 ± 3.42) mm and (1.06 ± 0.38) ％,respectively,which were lower than (15.52 ± 3.98) mm and (1.46 ± 0.20)％ of control group,the differences were statistically significant (P =0.000).The AUCs and their corresponding 95％ confidential intervals(CI) were 0.77[95％ CI(0.67,0.87)] and 0.82[95％ CI(0.73,0.91)],respectively.Combined ROC analysis based on the 2 indexes revealed an elevated AUC of 0.89 [95％ CI(0.83,0.95)],the differences were statistically significant(P =0.04).Conclusion The endometrial thickness and 48 hours blood HCG ratio can be acted as useful predicative biomarkers for detection of EP.A combination of the two indexes could be a useful predicative biomarker for future clinical trials with EP and may act as a suitable add-on biomarker to the panel of methods already existing for EP.

Adrenergic receptors are members of the G-protein coupled receptor superfamily. Recent studies revealed that these adrenergic receptors are playing an important role in the growth and metastasis of prostate cancer cells. The expression of adrenergic receptors rises significantly in prostate cancer cells and tissues. Agonists of these receptors promote the growth and mobility of prostate cancer cells, while antagonists may suppress their proliferation, trigger their apoptosis, and inhibit their metastasis. Clinically, receptor antagonists can significantly reduce the risk of prostate cancer and improve its prognosis after androgen depravation therapy. This article presents an overview on the roles of adrenergic receptors in prostate cancer.
