刺五加注射液及抗凝剂对糖尿病足的早期干预治疗

目的观察刺五加注射液及抗凝剂(潘生丁、肠溶阿斯匹林)对糖尿病足早期干预治疗的影响。方法将符合1999年WHO诊断标准的100例糖尿病合并早期足病变的患者分为两组:干预治疗组50例,对照组50例。在控制血糖、血压、糖尿病教育的基础上,干预组予以静滴刺五加注射液及口服抗凝剂(潘生丁、肠溶阿斯匹林)治疗,对照组为口服VitB1、VitB6、复方丹参片治疗。观察治疗前后两组患者足背动脉搏动、皮肤颜色、温度,痛、温、触觉等相关指征,血糖、HbA1c、血TG、TC、HDL-C,及血流变学、眼底病变、心脑血管事件发生率等。结果干预组糖尿病足病变治疗好转率高,恶化发展率低,心脑血管事件发生率少。血脂、血流变学、下肢血管多普勒彩超及眼底病变等好转改善明显,与对照组比较差异有统计学意义(P<0.05或P<0.01)。结论刺五加注射液及抗凝剂(潘生丁、肠溶阿斯匹林)对糖尿病足病变的早期干预治疗疗效显著,有重要的临床意义。     

Treatment of pigment epithelial detachments due to age-related macular degeneration with intra-ocular C3F8 injection*

Purpose: To flatten pigment epithelial detachments (PED) cue to age-related macular degeneration in an attempt to visualize the underlying choroidal neovascularization by fluorescein angiography (FA) and reveal a treatment target. Methods: Nine patients with PED received intravitreal gas injections via the pars plana and postured face down. Fluorescein angiograms were obtained before and after gas injection. In two patients, retinal scotopic sensitivity was also measured. Results: Eight patients demonstrated change in the shape and size of the PED following gas injection. Four patients showed a better delineation of underlying structures on FA. Three patients had focal laser treatment to the newly visible choroidal neovascular complex, but this was successful in only one patient with flattening of the PED. Conclusion: Pigment epithelial detachments can be modified by intravitreal gas injection in some patients, but this treatment did not have a major impact on overall outcome or management.

Contrast on T2-weighted images of the lumbar spine using fast spin-echo and gated conventional spin-echo sequences

A prospective study in 31 patients was designed to compare contrast quantitatively using axial conventional, gated spin-echo T2-weighted (T2W) (SE) (asymmetrical echo TE 30 and 80 ms) and axial dual-echo fast spin-echo (FSE) sequences (TE_eff20 and 120 ms) to image lumbar discs, nerve roots, and cerebrospinal fluid CSF. We used two quantitative measures, percent (%) contrast and contrast-to-noise ratio (CNR), to compare the sequences. The FSE sequence had greater % contrast and CNR on the first and second echo images for both disc and nerve root detection using these scan parameters. An axial FSE sequence, therefore, provided contrast characteristics similar to those of gated axial T2W SE sequence in the lumbar spine, with a 60% saving in acquisition time. The FSE sequence is now our standard axial T2W study for the lumbar spine.

Comparison of Simulated and in-Vivo Plasma Levels of Cilastatin Following Intravenous in-Line Drug Administration

The primary objective of this work was to establish a method to simulate the plasma levels of cilastatin, a model drug, following an intravenous in-line delivery scheme. In-vivo data in dogs obtained from this work were used to demonstrate the validity of the proposed approach. The in-line drug delivery system consists of a drug containing device which is placed between a large volume parenteral and a patient. Numerous advantages have been identified for this automatic in-line reconstitution delivery system. The numerical convolution integral algorithm was used in this work to perform plasma profile simulation. The results indicated that the simulated cilastatin plasma profile following in-line delivery closely agreed with the in-vivo data.     

Disc herniation in the lumbar spine during growth: Long-term results of operative treatment in 18 patients

We studied 18 patients who had undergone surgery for herniated lumbar discs between the ages of 11 and 17 years. The inclusion criteria for girls was an age of 15 years or below and for boys 17 or below at surgery. The mean follow-up time was 10 years and the clinical outcome was good. Age at surgery and length of the follow-up had no effect on the result. The radiological disc height at follow-up did not correlate with the follow-up time or age of the patient at operation. MRI scans at follow-up from ten patients operated at less than 15 years of age revealed multilevel disc degeneration but favourable clinical results.     

经纤支镜局部注射抑瘤仙(Immusyn)治疗肺癌临床观察(附9例报告)
