胰岛素强化治疗在2型糖尿病骨折患者围手术期的应用

Objective To investigate the best way to control the blood sugar level during the perioperation of bone fracture patients with type 2 diabetes(T2DM).Methods Bone fracture patients with T2DM were randomly divided into three groups:continuous subcutaneous insulin infusion group(insulin aspart,group CSII,n=20),glargine treatment group(insulin aspart+insulin glargine,group GA,n=20),and NPH treatment(insulin aspart+rh-insulin,group NA,n=20).The levels of fasting plasma glucose(FPG)and the 2 hours postprandial glucose(2h PG),blood glucose fluctuation(BGF),insulin dosage(ID),good effective time(GET),incidence of hypoglycemia,dawn phenomenon and infection,average time of stitches removal(ATSR),average hospitalized length(AHL)of three groups were compared.Results FPG and 2hPG,ID in group CSII[(6.32±1.18)mmol/L,(7.72±1.53)mmol/L,(35.40±1.60)IU]and group GA [(6.25±0.88)mmol/L,(7.32±1.17)mmol/L,(36.20±0.80)IU]were significantly lower than those of group NA [(7.44±1.36)mmol/L,(8.52±0.76)mmol/L,(40.50±2.40)IU,all P<0.05],simulaneously,BGF,GET incidence of complications,ATSR,AHL of group CSII and GA were significantly lower than those of group NA(all P<0.05).There were not significant difference between group CSII and group GA.Compared with group CSII,group GA had less costs in-hospital and better practicability.Conclusion Both CSII and insulin glargine combined with insulin aspart can effectively,safely,rapidly and stablely control hyperglycemia.and might be the first choice to control blood sugar for bone fracture patients with T2DM in perioperation.     

Hepatic Disposition Characteristics of Electrically Charged Macromolecules in Rat in Vivo and in the Perfused Liver

The effect of electric charge on the hepatic disposition of macromolecules was studied in the rat. Charged derivatives of dextran (T-70) and bovine serum albumin (BSA), mitomycin C–dextran conjugates (MMC-D), and lactosaminated BSA (Lac-BSA) were employed as model macromolecules. After intravenous injection, cationic macromolecules were rapidly eliminated from plasma because of their extensive hepatic uptake, while anionic and neutral macromolecules were slowly eliminated. Cationic macromolecules were recovered from parenchymal and nonparenchymal hepatic cells at a cellular uptake (per unit cell number) ratio of 1.4–3.2, while that of Lac-BSA was 14. During liver perfusion using a single-pass constant infusion mode, cationic macromolecules were continuously extracted by the liver, with extraction ratios at steady-state (E _ss) ranging between 0.03 and 0.54, whereas anionic and neutral macromolecules were almost completely recovered in the outflow at steady state. The E _ss for cationized BSA (Cat-BSA) and cationic MMC-Dcat were concentration dependent and decreased at low temperatures and in the presence of colchicine and cytochalasin B. The possible participation of the internalization process in the uptake of cationic macromolecules by hepatocytes was suggested.     

临床输液反应的分析与预防

目的对临床发生的输液反应进行分析,找出发生的原因,探讨预防措施。方法:对30例输液反应资料进行分析。结果:以热原反应最为多见,占76.67%,而过敏反应,占16.67%,局部反应,占6.67%。结论:严格执行消毒制度,遵守无菌操作规程,把好药品和输液器具质量关,合理用药,注意配伍等是减少临床输液反应的关键。     

骨外科患者拔尿管时注入药物对排尿的影响

目的探讨提高长时间留置导尿管病人拔管后2h内排尿成功率的方法。方法按入院先后随机将64例导尿的男性骨折病人分两组,单数为观察组,双数为对照组。对照组常规拔尿管,观察组拔尿管时遵医嘱注入地塞米松5mg+2%利多卡因5ml+生理盐水5ml+庆大霉素8万U,比较首次排尿的自觉症状,包括尿痛、排尿困难、排尿障碍等。结果观察组较对照组病人首次排尿出现自觉症状的例数明显减少(P<0.01),有显著性差异。结论拔尿管时注入药物安全有效,明显提高了长期置管病人拔除尿管后首次排尿的成功率,减轻了病人的痛苦,有广泛的应用价值。     

实验性小肠动脉出血的垂体后叶素灌注治疗

经动脉导管灌注垂体后叶素治疗１０条犬小肠出血的实验研究结果表明，垂体后叶素灌注治疗的效果与出血部位累及的血管大小及出血速率有关。还提示垂体后叶素对较大血管引起的出血灌注治疗无效，其引起血管的收缩作用主要在末梢小血管。

Raised intracranial pressure,the syndrome of inappropriate antidiuretic hormone secretion,and arginine vasopressin in tuberculous meningitis

Intracranial pressure (ICP) monitored shortly after admission over a period of 1 h in 31 children with tuberculous meningitis (TBM) was significantly higher (median 22.5 mm Hg, range 8.4–50.9 mmHg) in 19 children with laboratory evidence of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) than in 12 children without such evidence (median 16.2 mmHg, range 5.8–42.5 mmHg; P = 0.027). Neither plasma nor cerebrospinal fluid arginine vasopressin (AVP) was related to ICP (r = 0.33 and 0.13 respectively). Mean arterial pressure (MAP) was measured in 23 children and a moderate correlation was found with plasma AVP (r = 0.62; P = 0.0019). In TBM, plasma AVP may be secreted as a response to raised ICP in an effort to raise MAP and maintain cerebral perfusion pressure. In this setting excess fluid may be inappropriately retained, leading to hyponatremia and hypo-osmolemia.
