Objective To investigate the clinical features of moyamoya disease complicated with Graves′disease and the efficacy of extra-and intra-cranial revascularization. Methods The clinical data of 4 patients with moyamoya disease complicated with Graves′disease were analyzed retrospectively. Among them,three were females and one was a male. Their mean age was 32 ± 7 years. After medical treatment, their thyroid function was normal. The patients were treated with superficial temporal artery-middle cerebral artery bypass grafting. Results (1) Three patients showed cerebral infarction and one showed frequent transient ischemic attack. DSA confirmed that 2 patients had unilateral moyamoya disease and 2 had bilateral moyamoya disease. Head MRI revealed brain infarcts. (2) The thyroid function was normal after drug treat-ment,the symptoms of moyamoya disease were stable in 3 cases. One patient had high metabolic symptoms, such as high fever and accelerated heart rate within one week after procedure. The patients were followedup for 6 to 18 months,one was good,3 were excellent,and there was no recurrence of Graves′disease. Postoperative head MRI revealed that the 4 patients did not have new brain infarcts. MRA showed that the arterial filling in cerebral sulci in the ischemic lesion areas was obviously improved compared with that before procedure. Retrograde filling of the ipsilateral middle cerebral artery M2-M3 segment was observed in 2 patients. Postoperative single photon emission computed tomography perfusion imaging revealed that the ischemic perfusion lesions on the operated sides were obviously improved compared with those before procedure. Conclusion When complicated with Graves′ disease,the symptoms of moyamoya disease will aggravate. It manifests as acute and chronic cerebral ischemia. After controlling the symptoms of hyperthyroidism,most cerebral ischemic symptoms can be alleviated. Superficial temporal artery-middle cerebral artery bypass grafting may establish an effective collateral circulation and improve the clinical symptoms.

Objective:To investigate the relationship between FA,ET-1,Hcy and VEGF in patients with pregnancy induced hypertension.Methods:Selected 80 cases of patients with pregnancy induced hypertension who were treated in our hospital from January 2013 to September 2016,divided into A group (40 cases),and preeclampsia and preeclampsia B group (40 cases),60 cases of normal late pregnant women as C group,60 cases of normal non pregnant women as D group.The plasma levels of FA,ET-1,Hcy and VEGF in each group were detected,and the correlation analysis was performed.Results:The plasma levels of FA and VEGF of group B were lowest in the four groups (P＜0.05),the plasma ET-1 and Hcy levels of group B were highest (P＜0.05).The plasma FA and VEGF levels of women with pregnancy induce hypertension were lower than those of the healthy late pregnant women.The plasma ET-1 and Hcy levels were higher (P＜0.05).The multivariate logistic regression analysis showed that FA,ET-1,Hcy and VEGF levels were risk factors for pregnancy induce hypertension.Conclusion:The elevation of plasma Hcy level caused by FA deficiency in pregnancy might be related to the development of the disease and the incidence of pregnancy induced hypertension syndrome,VEGF might be an important factor in the occurrence and development of pregnancy induced hypertension syndrome.

A novel member of extremely halophilic archaea, strain AJ2, was isolated from Ayakekum Lake located in Altun Mountain National Nature Reserve of Xinjiang Uygur Autonomous Region in China. The strain AJ2 requires at least 10% (w/v) NaCl and grows 10% to 30% (optimum at 20%). Phylogenetic analysis based on 16S rDNA sequence comparison revealed that strain AJ2 clustered to three Natrinema species with less than 97.7% sequence similarities, suggesting AJ2 is a novel member of Natrinema. A bacteriorhodopsin-encoding (bop) gene was subsequently detected in the AJ2 genome using the polymerase chain reaction technique. The cloning and sequencing of a 401 base pairs fragment indicated the deduced amino acid sequence of bop from AJ2 is different from that reported for bacteriorhodopsins. This is the first reported detection of a bop gene in Natrinema.

OBJECTIVETo investigate the effcacy of the staple fixation for the treatment of hamate metacarpal joint injury.

METHODSFrom May 2009 to November 2012,16 patients with hamate metacarpal joint injury were treated with staple fixation including 10 males and 6 females with an average age of 33.6 years old ranging from 21 to 57 years. Among them, 11 cases were on the fourth or fifth metacarpal base dislocation without fractures, 5 cases were the fourth or fifth metacarpal base dislocation with avulsion fractures of the back of hamatum. Regular X-ray review was used to observe the fracture healing, joint replacement and position of staple fixation. The function of carpometacarpal joint and metacarpophalangeal joint were evaluated according to ASIA (TAM) system evaluation method.

RESULTSAll incision were healed well with no infection. All patients were followed up from 16 to 24 months with an average of (10.0 +/- 2.7) months. No dislocation recurred, the position of internal fixator was good,no broken nail and screw withdrawal were occurred. Five patients with avulsion fracture of the back of hamatum achieved bone healing. The function of carpometacarpal joint and metacarpophalangeal was excellent in 10 cases,good in 5 cases, moderate in 1 case.

CONCLUSIONThe application of the staple for the treatment of hamatometacarpal joint injury has the advantages of simple operation, small trauma, reliable fixation, early postoperative function exercise and other advantages, which is the ideal operation mode for hamatometacarpal joint injury.

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.

Sodium houttuyfonate (SH) is a derivative of effective component of a Chinese material medica, Houttuynia cordata, which is applied in anti-infection of microorganism. But, the antimicrobial mechanisms of SH still remain unclear. Here, we firstly discovered that SH effectively inhibits the three types of virulence related motility of.Pseudomonas aeruginosa, i.e., swimming, twitching and swarming. The plate assay results showed that the inhibitory action of SH against swimming and twitching in 24 h and swarming in 48 h is dose-dependent; and bacteria nearly lost all of the motile activities under the concentration of 1 x minimum inhibitory concentration (MIC) (512 mg x L(-1) same as azithromycin positive group (1 x MIC, 16 mg x L(-1)). Furthermore, we found that the expression of structural gene flgB and pilG is down-regulated by SH, which implies that inhibitory mechanism of SH against motility of P. aeruginosa may be due to the inhibition of flagella and pili bioformation of P. aeruginosa by SR Therefore, our presented results firstly demonstrate that SH effectively inhibits the motility activities of P. aeruginosa, and suggest that SH could be a promising antipseudomonas agents in clinic.
