采用固相反应法制备高介电常数石榴石铁氧体材料。基于优化的材料性能,利用AnsysHFSS仿真软件对X波段微带环行器进行三维电磁场仿真分析,并结合微电子工艺进行实物研制。实验结果表明,高介石榴石铁氧体材料的介电常数为26,在9GHz附近材料的铁磁共振线宽为100Oe。器件仿真结果表明,在8~12GHz频率范围内,微带环行器的插入损耗小于0.4dB,隔离度大于20dB,电压驻波比小于1.2,表现出良好的环行特性。器件实物测试结果表明,在X波段内插入损耗小于1dB,隔离度大于18dB,驻波比小于1.25。造成实测性能变差的原因主要来自铁氧体较高的介电损耗,样品加工和测试过程产生的误差也有影响。相比于常规介电常数石榴石铁氧体材料研制的微带环行器,该环行器具有更小的体积和重量,实现了器件小型轻量化。

AIM： To evaluate the feasibility and efficacy of endo- scopic submucosal dissection （ESD） for foregut neuro- endocrine tumors （NETs）. METHODS： From April 2008 to December 2010, pa- tients with confirmed histological diagnosis of foregut NETs were included. None had regional lymph node enlargement or distant metastases to the liver or lung on preoperative computerized tomography scanning or endoscopic ultrasonography （EUS）. ESD was attempted under general anesthesia. After making several mark-ing dots around the lesion, a mixture solution was injected into the submucosa. The mucosa was incised outside the marking dots. Dissection of the submu- cosal layer beneath the tumor was performed under direct vision to achieve complete en bloc resection of the specimen. Tumor features, clinicopathological char- acteristics, complete resection rate, and complications were evaluated. Foregut NETs were graded as G1, G2, or G3 on the basis of proliferative activity by mitotic count or Ki-67 index. All patients underwent regular follow-up to evaluate for any local recurrence or dis- tant metastasis. RESULTS： Those treated by ESD included 24 patients with 29 foregut NETs. The locations of the 29 lesions are as follows： esophagus （n = 1）, cardia （n = 1）, stomach （n = 23）, and duodenal bulb （n = 4）. All le- sions were found incidentally during routine upper gastrointestinal endoscopy for other indications, and none had symptoms of carcinoid syndrome. Preop- erative EUS showed that all tumors were confined to the submucosa. Among the 24 gastric lesions, 16 le- sions in 11 patients were type I gastric NETs arising in chronic atrophic gastritis with hypergastrinemia, while the other 8 solitary lesions were type Ⅲ because of absence of atrophic gastritis in these cases. All of the tumors were removed in an en bloc fashion. The av- erage maximum diameter of the lesions was 9.4 mm （range： 2-30 ram）, and the procedure time was 20.3 rain （range： 10-45 rain）.

Photometric observations of AH Cnc, a W UMa-type system in the open cluster M67, were car- fled out by using the 50BIN telescope. About 100h of time-series/3- and V-band data were taken, based on which eight new times of light minima were determined. By applying the Wilson-Devinney method, the light curves were modeled and a revised photometric solution of the binary system was derived. We con- firmed that AH Cnc is a deep contact （f = 51%）, low mass-ratio （q - 0.156） system. Adopting the distance modulus derived from study of the host cluster, we have re-calculated the physical parameters of the binary system, namely the masses and radii. The masses and radii of the two components were estimated to be respectively 1.188（4-0.061） Me, 1.332（4-0.063） RQ for the primary component and 0.185（4-0.032） Me, 0.592（4-0.051） Re for the secondary. By adding the newly derived minimum timings to all the available data, the period variations of AH Cnc were studied. This shows that the orbital period of the binary is con- tinuously increasing at a rate of dp/dt = 4.29 x 10-10 d yr-1. In addition to the long-term period increase, a cyclic variation with a period of 35.26 yr was determined, which could be attributed to an unresolved tertiary component of the system.

BACKGROUND: Ischemic-type biliary lesions (ITBLs) play an extremely important role in influencing the long-term survival and quality of life of recipients after orthotopic liver transplantation (OLT). Some patients can be cured by interventional therapies, however others lose their grafts at last and receive liver retransplantation (re-OLT). The aim of this study was to analyze the data of 66 patients who had received re-OLT at our center because of ITBL and to discuss the treatment of ITBL after OLT. METHODS: We retrospectively analyzed 66 re-OLT cases due to ITBL from September 2001 to February 2007 at our center. The Kaplan-Meier method and the Cox-Mantel test were used to identify factors associated with mortality for univariate analysis and multivariate analysis, respectively. RESULTS: Fifty-five of 66 ITBL cases underwent interventional therapies before re-OLT. The actuarial survival at I month and I year for these patients was 83% and 74%, respectively. Prognostic factors for mortality in univariate analysis were model of end-stage liver disease score (MELD) >16.5 (chi(2)=5.856, P=0.016), cold ischemia time >8 hours (chi(2)=6.539, P=0.011), infections (chi(2)=5.550, P=0.018) and complications (chi(2)=12.168, P=0.002) after re-OLT. In the multivariate analysis (Cox regression), the risk factors independently associated with mortality were MELD score >16.5 (RR: 3.140; P=0.035), cold ischemia time >8.2 hours (RR: 0.192; P=0.016) and complications (RR: 3.896, P=0.003). CONCLUSIONS: The incidence of ITBL in China is higher than in other countries. Based on our experience, MELD score, cold ischemia time and complications after re-OLT are risk factors independently associated with mortality in retransplanted ITBL patients.

Repair techniques for short-distance peripheral nerve defects, including adjacent joint flexion to reduce the distance between the nerve stump defects, ＂nerve splint＂ suturing, and nerve sle eve connection, have some disadvantages. Therefore, we designed a repair technique involving intraoperative tension-free application of a nerve elongator and obtained good outcomes in the repair of short-distance peripheral nerve defects in a previous animal study. The present study compared the clinical outcomes between the use of this nerve elongator and performance of the conventional method in the repair of short-distance transection injuries in human elbows. The 3-, 6-, and 12-month postoperative follow-up results demonstrated that early neurological function recovery was better in the nerve elongation group than in the conventional group, but no signif- icant difference in long-term neurological function recovery was detected between the two gro ups. In the nerve elongation group, the nerves were sutured without tension, and the duration of postoperative immobilization of the elbow was decreased. Elbow function rehabilitation was significantly better in the nerve elongation group than in the control group. Moreover, there were no security risks. The results of this study confirm that the use of this nerve elongator for repair of short-distance peripheral nerve defects is safe and effective.
