He had an uneventful postoperative recovery. Elderly patients who have emphysematous cholecystitis may present with only right upper abdominal pain. Other signs may be absent. Preoperative diagnosis can be difficult. When the gallbladder is poorly visualized and gas is suspected on ultrasonography, it should be defined by plain film and computed tomography and emergent cholecystectomy is needed to minimize the risk of mortality.

急性气肿性胆囊炎的老年患者，经常只以右上腹胀痛表现而缺乏典型的症候，术前诊断不容易，当超音波检查发现胆囊无法清楚显现而怀疑胆囊内有气体存在时，必须安排腹部X光及电脑断层作更进一步确认，一旦确立诊断，必须作紧急手术治疗以降低死亡的危险性。

In this paper, several traditional models for computing are introduced at first. Conferring probability theory, the load boundary condition of that collector is analyzed, the characteristic values of Tubesheet in different design reference periods are computed. Based on homogenization method, after lots of numerical experiments, the mechanical characteristic of Tubesheet controlled different structure parameters is studied, and an empiristic formulas that could simplify Tubesheet to stiffen plate is gained. Then, G-M method is employed and Tubesheet is simplified to a normal plate.

本文在总结传统计算方法的基础上，参考概率设计方法，分析了大型袋式除尘器的荷载边界条件，计算了不同设计基准期下的花板可变荷载标准值，结合均匀化方法，通过大量数值实验，得出了不同参数对花板受力性能的影响规律，并拟合了将花板简化为加劲板的经验公式，再参考正交异性板法，最终推导了花板简化为均匀平板的经验公式。

objective to explore the reasonable utilization of cephalosporins in chronic renal failure patients with cephalosporin encephalopathy.method we retrospectively analyzed the clinical characteristics of 29 crf patients,who developed encephalopathic syndrome and was treated with cephalosporin.results the encepha1opathic syndrome include (1)mental confusion in 4 cases;(2)unconsciousness in 2 cases;(3)seizure in 23 cases.physical examination did not show signs of cerebral focal injury.computed tomography of the brain in 29 patients did not show acute lesions.the state of neurotoxicity was completely recovered after discontinuation of cephalosporins.conclusion cephalosporins used in conventional doses or reduced doses can cause temporary encephalopathy in patients with crfwhich might due to prolongation of drug half life.

目的 通过研究慢性肾功能衰竭患者抗生素脑病的发病机制和临床特点，探讨头孢菌素在crf患者中的合理应用。方法 29例crf患者在使用常规剂量或减量使用头孢菌素后出现神经精神症状，诊断为抗生素脑病，将其临床资料进行回顾性分析。结果神经精神症状表现多样：(1)精神异常4例，表现为胡言乱语、烦躁不安、睡眠倒错；(2)意识障碍2例，表现为嗜睡、昏睡、神志不清；(3)癫痫样抽搐23例，表现为肌阵挛、全身抽搐、癫痫样发作；部分患者同时出现几组症状。所有患者均无神经系统定位体征，行颅脑ct检查无急性病变。

Methods 100 cases with enophthalmos and orbital fracture were operated, and examinated by using the computed tomography, flash electroretinogram and pattern visual evoked potentials before and after operation.

应用螺旋CT影像和视觉电生理检查技术对100例施行眼眶重建和眼球复位手术的患者进行观察研究。

Optimization of contrast agents for small intestine computed tomography enteroclysis.

小肠CT造影对比剂的优选。

AIM: To evaluate which contrast agents can fully distend the intestinal canal and demonstrate the enteric cavity and intestinal wall in computed tomography enteroclysis.

摘要目的：评价何种对比剂在小肠CT造影时能充分充盈扩张肠管、不易形成伪影，在显示小肠肠腔、肠壁方面最佳。

Computed tomography enteroclysis and magnetic resonance enteroclysis, as new imaging technologies, provide three-dimensional imaging capabilities and excellent soft-tissue contrast, which can analyze the abnormalities of peripheral intestinal structure as well as the tunica mucosa, greatly advancing the cognition of the imaging diagnosis for the intestinal disease.

新的影像技术CT小肠灌肠造影、MR小肠灌肠造影具有良好的软组织对比度及三维成像能力，不仅可以观察黏膜，同时能够分析肠管周围的改变，提高了人们对小肠疾病影像诊断的认识。

In this paper the mathematical models and methods for GPS single-point positioning are studied systematically on the theory.All kinds of error correction formulas are studied,such as ironsphere correction,troposphere correction,relativistic effect correction,earth rotation correction ,earth tides correction ,satellites antenna phase center offset correction. GPS single-point positioning programs is coded with pseudoranges and broadcast ephemerides,phases and broadcast ephemerides,and phases and precise ephemerides.And a great amount of computation has been done using the data collected .The results are computed with the 24 hour pseudoranges observation data before and after the canceling of the SA.

本文从理论上系统地研究了GPS单点定位的数学模型和方法，研究了各项误差改正公式，例如电离层改正、对流层改正、相对论周期部分改正、地球旋转改正、地球固体潮改正、卫星天线相位中心偏差改正；编写了伪距与广播星历、相位和广播星历及相位和精密星历的定位程序，并使用有关数据进行了大量的计算工作。

Methods: 28 patients with isolated patellofemoral complications after total knee arthroplasty were scaned by computed tomography. The epicondylar axis and tibial tubercle were used as references to measure rotational alignment of the femoral and tibial components.

28例施行人工全膝关节置换术后出现单纯髌股关节并发症的患者进行膝关节轴位CT扫描，选择股骨髁上轴和胫骨结节作为CT扫描的参考标志来测量股骨假体和胫骨假体的旋转角度，分析旋转稳定性与髌股关节并发症的相关性。
