生化修饰疗法对晚期恶性肿瘤病人的治疗与护理观察

目的：探讨生化修饰疗法对晚期恶性肿瘤病人的治疗效果。方法：对57例晚期恶性肿瘤病人采用置管经输注泵输注化疗药物治疗与护理。结果：此法较全身化疗疗效高，毒副作用小。尤其适用于一般状况差又难于耐受全身化疗的晚期消化系统恶性肿瘤病人。结论：生化修饰疗法安全、有效、方便、费用低，值得推广。

离体牙上釉珠的观测与临床意义

本文从12379枚离体牙上观测了釉珠的发生率、发生部位、形态、直径大小。结果釉珠的发生率为2.49％,以上颌第三磨牙发生率最高,下颌第一磨牙次之。最常发生的部位是在冠颈部的根分叉处,上颌磨牙的釉珠多呈园形,下颌磨牙釉珠多呈梭形。釉珠最大直径为3.2mm,最小为0.5mm,平均为1.56mm。结合文献认为釉珠是一种牙齿形态发育异常,它对牙周病的发生、发展、治疗与预后有重要影响,口腔科医师对这种牙齿形态变异应予以重视。     

Screening Mouse Genes Related to Blastocyst Implantation by Using PCR Subtraction

Objective To identify genes that may be related to embryo implantation Materials & Methods The PCR subtraction technique was applied at implantation and inter-plantation sites on day 4. 5 of pregnancy in mice. Two novel Expressed Sequence Tags (ESTs ), EST8 and EST81 were identified; their expression in tissues was analyzed by Northern blotting, and their full-length cDNAs were synthesized by PCR.Results We found that these two novel ESTs (EST8and EST81) were noticeably expressed in implantation site in the mouse on day 4. 5 of pregnancy. EST8 was expressed at high level in livers and implantation sites of the mice, while at low level in ovaries and inter-plantation sites. EST81 was predominantly expressed in implantation site and ovary, and at low level in all other tissues. Their complete cDNAs, 1 665bp and 1 264 bp respectively, were synthesized by using PCR.Conclusion The two full-length cDNAs were responsible for embryo implantation,and their functions need to be further studied.

严重胸腹部闭合性联合伤致呼吸心跳停止成功救治1例

报告1例严重胸腹部闭合性联合伤所致的急性呼吸心跳骤停得到成功救治的病例。闭合性胸腹联合伤后,因病情可能发展,应随时注意复查胸片、血气等;若基层医院条件不够,应及时转往上级医院,以免延误患者的治疗。     

手术治疗125例分化性甲状腺癌的5年随访结果分析

目的：探讨甲状腺全切除术在治疗分化性甲状腺癌中的临床应用价值。方法：采用我院1988年1月～2001年5月甲状腺全切除术或甲状腺侧叶切除加峡部切除术治疗分化性甲状腺癌125例,对其手术并发症发生、局部复发、转移情况及术后5年生存率进行回顾性对比分析。结果：甲状腺全切除术术后并发症发生率高于甲状腺侧叶切除加峡部切除术组;局部复发、转移率低于侧叶切除加峡部切除术组;5年生存率两组无显著性差异。结论：甲状腺全切除术是治疗甲状腺癌有效的手术方式,但应掌握手术指征,改进、提高手术技术,减少并发症。     

Laparoscopic Local Resection Based on Sentinel Node Evaluation for Early Gastric Cancer: A Preliminary Report

We previously reported that lymphatic mapping using isosulfan blue can be used to identify sentinel nodes (SNs). This study was undertaken to evaluate the feasibility of using the SN technique in treating early gastric cancer and to explore its usefulness for minimal invasive surgery. Twenty-three patients with early gastric cancer who underwent SN biopsy were retrospectively evaluated. Based on SN evaluation, individualized surgery was performed in five patients with T1N0M0 gastric cancer. When pathological examination of frozen sections revealed metastasis in SNs, we performed a standard D2 gastrectomy. Laparoscopic local resection was applied when the SN biopsy was negative. Our results showed that the success rate with SN biopsy in early gastric cancer was 100%, as were the accuracy, sensitivity, and specificity. All five patients with early gastric cancer had SNs negative for metastases both by frozen section and by postoperative pathology. Thus, all these patients underwent laparoscopic local resection without extended lymphadenectomy. We conclude that SN biopsy is a useful tool to individualize the operative procedure, and laparoscopic local resection can be safely performed using SN guidance in selected patients with early gastric cancer.
