Results Pulmonary carcinosarcoma and blastoma both were found to be rare malignant tumors, and both epithelial and mesenchymal elements can be seen under the microscopy with different characteristic features.

结果 肺癌肉瘤及肺母细胞瘤均为肺内罕见的恶性肿瘤，镜下均可见上皮及间质两种成分，但又有其不同之处，手术前很难确诊。

Objective To investigate the applied value of function magnetic resonance imaging and electrocorticogram in surgery for the tumor in the eloquent brain areas with associated epilepsy.

目的 探讨术前功能磁共振成像和术中皮质脑电图在伴继发性癫脑肿瘤手术中的应用价值。

Bleeding of limbus cornea in LASIK affect the operation effect and much attention should be paid in the operation.

特别是随着波前像差的应用和波前像差引导的个性化LASIK的开展，其对手术效果的影响将日显突出。

RESULTS: A total of 45 eyes from 45 patients were treated with the Ahmed glaucoma valve implant and its combination surgery. At a mean follow up of 9.7 months (range3～18months), the mean intraocular pressure was reduced from 36.8±12.3mmHg before the implant surgery to 18.0±4.5mmHg at the last follow up after surgery. The success rate was 87%.The best postoperative corrected visual acuity improved 16 eyes(35%).Transient postoperative hypotony and shallow anterior chamber occurred in 20% of cases.

结果：难治性青光眼45例（45眼）实行了Ahmed青光眼阀植入术或联合晶状体摘除、玻璃体切割、人工晶状体植入术等；术后平均观察(3～18)9.7mo；患者术前的平均眼压36.8±12.3mmHg，术后平均眼压18.0±4.5mmHg；手术成功率87%；术后最佳矫正视力提高16眼（35%），视力无变化21眼（47%），视力降低8眼（18%）；术后早期最常见的并发症是一过性浅前房及低眼压，发生率为20%，晚期最常见的并发症是滤过泡包裹，发生率是13%。

Methods The central corneal thickness of 637 patients (1210 eyes) of myopia was measured with DGH-4000 pachymeter before and 1、3 month after LASIK.

应用 DGH- 40 0 0型超声角膜测厚仪分别测量6 37例(12 10只眼)近视患者在施行 L ASIK手术前及术后 1月、3月的角膜中央厚度；根据术前的屈光度分为 4组，对各组所测得角膜中央厚度的数值进行分析。

Methods: The authors conducted medical record reviews and telephone interviews of 106 consecutive patients with ACL reconstruction using quadrupled semitendinosus-gracilis autograft from 2004 to 2006. Data included anthropometric measurements (height, mass, gender, and age at the time of surgery). Hamstring diameter was obtained using cylindrical sizers in 0.5-mm increments and recorded in the patient's surgical record. Correlation coefficients and stepwise, multiple linear regression were used to determine the relationship between the outcome variable and the predictor variables (age, gender, height, mass, and BMI). Independent sample t tests were used to compare hamstring graft diameter between genders.

从2004年到2006年作者对106名相关的采用股四头肌半腱肌-股薄肌自体移植重建前十字交叉韧带的病人进行了病历综述和电话随访，资料包括人体测量结果(手术时的身高，体重，性别和年龄)，腘绳肌肌腱的直径用计算机圆柱分检器以0.5毫米的增值测量并记录在病人的手术病历中，相关系数和逐步，多个直线回归被用来确定结果变量和猜测变量(年龄，性别，身高，体重和体重指数)之间的关系，独立样本的t检验被用来比较不同性别之间的腘绳肌腱移植物的直径。

The results suggested that the qualitative diagnosis of the lacrimal gland tumor could be made before operation according to the clinical features and the characteristics of CT image, and operation was the only way to cure it.

重点探讨术前的定性诊断及手术治疗问题。本组病例的诊治经过表明，通过临床表现及 CT的影像学特征能够在术前做出定性诊断。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
