Objective To investigate the clinical features of subarachnoid hemorrhagic moyamoya disease and the therapeutic effect of encephalo-duro-arterio-synangiosis (EDAS). Methods The clinical and imaging data of 38 patients with subarachnoid hemorrhagic moyamoya disease admitted to the Department of Neurosurgery,the 307th Hospital of PLA from January 2002 to April 2013 were analyzed retrospectively. Thirty-five patients underwent unilateral or bilateral EDAS (64-sides underwent EDAS,4 patients with aneurysms underwent endovascular embolization first),and 3 patients did not undergo any surgery. Results (1)Subarachnoid hemorrhagic moyamoya disease accounted for 10. 8%(38/353)of all the hemorrhagic moyamoya disease admitted in hospital over the same period,including 37 adults and 1 child. The male to female ratio was 1∶3. 22 (9/29),and the age of onset was 12 to 59 years. The mean age of patients was 39 ± 11 years. Four patients were combined with aneurysms. There were no significant differences in the distribution of Suzuki stage,anterior choroidal artery dilatation and posterior communicating artery dilatation in the remaining 34 patients without aneurysms between the bleeding sides and non-bleeding sides (P>0.05). (2 ) The patients were followed up for 13 -125 months (mean 51 ± 27 months ),two patients had rebleeding,one of them was intraventricular hemorrhage,the other was parenchymal hemorrhage. The postoperative modified Rankin score (mRS)was significantly lower in 35 patients whom were treated with EDAS. Compared with before surgery,there was significant difference (P<0. 05). The re-examination of positron emission tomography (PET)for 16 patients at 3 to 19 months after surgery showed that among the 23 surgically treated hemispheres,the cerebral metabolisms of 17 hemispheres were improved after surgery, and 6 did not have any change after surgery. The re-examination of whole brain digital subtraction angiography (DSA)at 5 to 30 months after surgery in 13 patients showed that revascularizations in 19 of 23 surgical hemispheres were effective. Conclusion Subarachnoid hemorrhagic moyamoya disease often occurs in adults,and women are more common. EDAS can achieve good revascularization effect and improve brain metabolism of patients,and thus relieve the symptoms of cerebral ischemia.

Objective: To explore the clinical value of plasma copeptin level on major adverse cardiovascular event (MACE) occurrence in patients with acute ST-segment elevation myocardial infarction (STEMI) during hospitalization.
Methods: Our research included 2 groups:STEMI group, n=80 and Control group, n=80 patients with stable coronary artery disease (CAD). All patients were treated in our hospital from 2012-06 to 2014-06. Plasma level of copeptin was detected by ELISA, other relevant examinations were conducted to study the MACE occurrence in STEMI patients.
Results: Plasma copeptin level in STEMI group (523.26 ± 142.69) pg/ml was higher than that in Control group (345.25 ± 89.36) pg/ml, P<0.05. In STEMI group, there were 28/80 (35%) patients suffered from MACE, compared with non-MACE patients, they had increased plasma copeptin, cardiac muscle protein I (cTnI), kinase isoenzyme (CK-MB) and left ventricular ejection fraction (LVEF), P<0.05. Multivariate regression analysis indicated that plasma copeptin, cTnI and LVEF were the independent risk factors for MACE occurrence. According to occurred area under the curve, compared with cTnI and CK-MB, plasma copeptin level had the higher predictive value to judge the ROC, positive/negative possibility, sensitivity and speciifcity for MACE occurrence in STEAMI patients, P<0.05.
Conclusion: Plasma copeptin level could effectively predict MACE occurrence in patients with acute STEMI during
hospitalization, it may predict their prognosis at certain point.

Objective: To observe the clinical efficacy of herb-partitioned spreading moxibustion at Baliao points plus climen for diminished ovarian reserve (DOR). Methods: A total of 60 patients with DOR were randomized into a spreading moxibustion group and a Western medicine group by the random number table method, with 30 cases in each group. The Western medicine group was treated with climen, starting from the 5th day of the menstrual cycle for 21 d. The spreading moxibustion group was treated with herb-partitioned spreading moxibustion at Baliao points on the basis of the medication in the Western medicine group, 1 h per time, once a week. The treatment was performed for 1 month as one treatment course in both groups, for 3 courses in total. The serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in the patients were measured before and after treatment. The peak systolic velocity (PSV) and resistance index (RI) were also detected. The traditional Chinese medicine (TCM) symptom score was evaluated. The clinical efficacy was evaluated after treatment. Results: The total effective rate in the spreading moxibustion group was 93.3%, which was significantly higher than 80.0% in the Western medicine group, and the difference between the groups was statistically significant (P<0.05). After treatment, the TCM symptom scores, the serum FSH levels, FSH/LH ratios and RI in both groups decreased, and the intra-group differences were all statistically significant (all P<0.05). The serum E2 level and PSV increased compared with those in the same group before treatment, and the intra-group differences were statistically significant (all P<0.05). After treatment, the TCM symptom score, the serum FSH level, FSH/LH ratio and RI in the spreading moxibustion group were lower than those in the Western medicine group, while the serum E2 level and PSV were higher than those in the Western medicine group, and the differences between the groups were statistically significant (all P<0.05). Conclusion: Herb-partitioned spreading moxibustion at Baliao points plus climen can produce valid therapeutic efficacy for DOR. It can improve the clinical symptoms, regulate serum hormone levels and increase ovarian blood perfusion, thus improving ovarian reserve function, producing more significant efficacy than climen alone.
