稳定性核素测定大鼠小肠蛋白质合成

目的：建立稳定性核素（[L-^15N]亮氨酸）测定大鼠小肠蛋白质合成率的方法。方法：分别测定静脉注射相同剂量[L-^15N]亮氨酸不同时相的大鼠小肠^15N丰度及不同剂量[L-^15N]亮氨酸同一时相的大鼠小肠^15N丰度。结果：大鼠小肠游离氨基酸池中^15N核素丰度在注射后0．5h内呈线性上升并达高峰，维持4h后缓慢下降，小肠蛋白质中的^15N丰度0．5h至12h基本维持不变；随着注射剂量的增加，大鼠小肠蛋白质分数合成率（FSR）亦增加，当[L-^15N]亮氨酸剂量在1．0mmol／kg以上，FSR并不随施加[L15N]亮氨酸剂量的加大而增加。结论：在进行大鼠小肠蛋白质合成率测定时，一次性静脉注射的测量最佳时限为0．5h，剂量为1．0mmol／kg。     

Performance and comparison of the Cockcroft-Gault and simplified Modification of Diet in Renal Disease formulae in estimating glomerular filtration rate in a Chinese Type 2 diabetic population.

AIMS: Our aim was to assess performances of the Cockcroft-Gault and simplified Modification of Diet in Renal Disease (MDRD) formulae in estimating glomerular filtration rate (GFR) in Chinese diabetic populations and their association with vascular risks. METHODS: A total of 1009 patients with Type 2 diabetes were categorized into low estimated GFR groups (GFR < 60 ml/min/1.73 m(2)) and control groups by the two equations. The performances of these formulae were assessed at different stages of kidney function. Carotid artery intima-media thickness (IMT) and the prevalence of diabetic retinopathy or albuminuria were compared among the groups. The ability of these formulae to identify established vascular risk markers using sensitivity, specificity, positive and negative predictive values were also compared. RESULTS: The prevalence of low estimated GFR was 32.7% with the Cockcroft-Gault formula and 5.2% with the MDRD formula, respectively. In low estimated GFR subjects by the MDRD formula, IMT was significantly thicker than those by the Cockcroft-Gault formula (1.2 mm vs. 1.0 mm; P < 0.05), with a higher prevalence of albuminuria (78.4 vs. 52.8%, P < 0.05) and diabetic retinopathy (46.5 vs. 30.5%; P < 0.05). The Cockcroft-Gault formula gave a specificity of 71.7% and a sensitivity of 37.0%, and the MDRD formula gave a specificity of 96.6% and a sensitivity of 7.9% in estimating low GFR relevant for established vascular risks. CONCLUSIONS: These formulae performed differently in Chinese diabetic populations. The simplified MDRD formula is minimally superior to the Cockcroft-Gault formula for its high specificity and positive predictive values in estimating low GFR relevant for vascular risks.

Investigation of the Effect of Neoadjuvant Chemotherapy on Stage Ⅱ Breast Cancer

OBJECTIVE To investigate the effect of neoadjuvant chemotherapy in treatment of Stage Ⅱ breast cancer. METHODS The data from 113 patients with breast cancer of the same pathologic type in Stage Ⅱ,during the period of 1995 to 2001,were analyzed retrospectively.Among the patients,47 were treated with neoadjuvant chemotherapy,and 66 received no adjuvant therapy before surgery（control group）.After the patients of the neoadjuvant chemotherapy group had received 2 courses of chemotherapy with the CMF regimen,the surgical procedure was conducted. RESULTS Complete remission（CR）was attained in 9 of the 47 cases receiving neoadjuvant chemotherapy and partial remission（PR）was reached for 22 cases.The rate of breast-conserving surgery was enhanced from 22.73%to 46.81%（P〈0.05）in the neoadjuvant treatment group. There was no difference in the 5-year overall survival（OS）and disease-free survival（DFS）rate between the two groups（P〉0.05）,but the 5-year OS and DFS of the cases with clinical tumor remission was higher compared to the control group（P〈0.05）. CONCLUSION Neoadjuvant chemotherapy can enhance the rate of breast conservation for Stage Ⅱ breast cancer and may improve the prognosis of the cases with clinical remission.     

CT导引经皮穿刺注射无水乙醇治疗溶骨性骨转移瘤

目的探讨CT导引下经皮穿刺注射无水乙醇（CT～PEI）治疗溶骨性骨转移瘤的价值及安全性。方法对17例骨转移瘤患者（25个病灶）采用CT—PEI治疗，使用无水乙醇和超化碘油10：1的混合剂，用CT精确定位、准确穿刺瘤灶并密切监控无水乙醇弥散情况及用量，以减少并发症。对接近椎管及椎间孔的病灶，采用利多卡因实验性治疗以避免严重并发症。术前及术后定期CT检查，3例病人行同位素骨扫描检查，与治疗前检查进行对照研究。对患者随访3～30个月观察其临床疗效。结果所有患者经1次CT—PEI治疗后，疼痛即明显减轻，经2～3次CT-PEI治疗后疼痛完全缓解（CR）16例（24处病灶），疼痛部分缓解（PR）1例。术后随访3个月时，23处病灶内肿瘤组织均发生坏死，被高密度碘油混合液均匀浸润。其中，9处病灶体积缩小。随访3～30个月，除1例因周边出现新的肿瘤浸润灶而再次出现疼痛，其余病例转移瘤处止痛效果无反复。所有病例无严重并发症。结论CT—PEI是一种治疗骨转移瘤有效、微创、安全、简便的方法，使骨转移瘤内肿瘤组织坏死，最大限度的杀灭肿瘤细胞，从而达到满意的止痛效果，明显改善恶性肿瘤溶骨性转移病人的生活质量。     

Peritoneal dialysis patient survival: a comparison between a Swedish and a Korean centre.

BACKGROUND: Dialysis patient mortality remains high, and this high mortality may be due to many factors. In peritoneal dialysis (PD) patients, old age, co-morbid diseases, malnutrition, low residual renal function (RRF) and a high peritoneal transport rate have been shown to influence survival, but the relative importance of these factors may differ between different patient populations. Besides, centre practice patterns may differ between centres and may influence patient survival. In addition, the literature suggests that dialysis patient survival may be better in Asian than in Caucasian patients. METHODS: The influence of centre and patient characteristics on patient survival was investigated in 132 Korean and 106 Swedish incident PD patients, who underwent initial biochemical measurements and assessment of adequacy of dialysis, nutritional status, RRF and peritoneal transport characteristics. RESULTS: At the start of PD, Korean patients had a higher prevalence of diabetes, peritoneal Kt/V(urea), peritoneal creatinine clearance and peritoneal fluid removal, and lower body mass index, RRF and dialysate to plasma creatinine concentration ratio (D/P Cr) compared with Swedish patients. Significantly more patients from Korea were placed on temporary haemodialysis before PD (100 out of 132) when compared with Swedish patients (21 out of 106). During the follow-up, there was a significantly higher rate of transfer to other units in Korea and a significantly higher rate of kidney transplantation in Sweden. On Kaplan-Meier analysis, overall patient survival did not differ and relative risk for death was also not different between the two centres even after adjustment for age, diabetes, cardiovascular disease, RRF and D/P Cr. On Cox proportional hazards multivariate analysis, age, diabetes, RRF and D/P Cr were found to be independent predictors of mortality in the combined cohort of patients. While age, diabetes and D/P Cr were independent predictors of mortality in Korean patients, age and RRF independently predicted mortality in Swedish patients. CONCLUSION: Although there were significant differences in centre and patient characteristics, we were unable to confirm a survival advantage for Korean over Swedish PD patients. The results of this study suggest that the reported difference in survival between Asian and Caucasian dialysis patients may have been due, in part, to differences in centre and patient characteristics rather than to race as such. The genetic influence on patient characteristics remains, however, to be elucidated.

不同疗法对肌筋膜疼痛病人的自主神经功能的影响

目的：本研究的目的是观察注射疗法及复合小针刀疗法治疗肌筋膜疼痛综合征对自主神经系统功能的影响。方法：选择40例诊断明确的肌筋膜疼痛病人，随机分为两组，每组20例。Ⅰ组：采用注射疗法治疗；IS组：采用注射疗法加小针刀治疗。观察两组病人治疗前后心率变异（HRV）的频域变化，低频LF、超低频LLF、高频HF、低高频比LF／HF及心率变异指数HR-Ⅵ；用视觉模拟评分法（VAS）评定治疗前后疗效并随访观察其远期疗效。结果：①HRV频域指标组内比较：LF、LLF、HF以及HRVI治疗前舆治疗后1min比较有显着性差异（P〈0．05），与5min、10min比较有非常显着性差异（P〈0．01）。LF／HF治疗前与治疗后5min、10min比较有显着性差异（P〈0．05）。组间治疗后1、5、10min，两两比较无显着性差异。②组间比较：病人治疗后临床症状、VAS评分均较治疗前降低．治疗前后IS组有非常显着性差异（P〈0．01）。两组VAS降低率有非常显着性差异（P〈0．01）。③回访病例中，两组治疗有效率比较有显着性差异（P〈0．05）。结论：注射疗法以及复合小针刀疗法均可有效改善肌筋膜疼痛病人的自主神经功能，其机制可能是通过调节、稳定自主神经系统功能达到缓解疼痛。注射疗法复合小针刀疗法的远期疗效优于单纯注射疗法。
