急性重症胆管炎的预后因素分析

目的分析急性重症胆管炎(ACST)的预后因素,探讨合理的治疗方案。方法对168例ACST病人的临床资料进行回顾性分析,采用卡方(χ2)检验进行统计处理。结果影响ACST的预后因素有年龄、入院时休克与否、是否合并器官功能障碍综合征(MODS)、治疗方式及手术时机,而既往有无胆管炎发作史与预后无明显相关。结论针对影响预后的因素,及时采取手术干预,可提高治疗效果、降低病死率。     

Acute infections in children are accompanied by oxidative modification of LDL and decrease of HDL cholesterol, and are followed by thickening of carotid intima-media.

BACKGROUND: Atherosclerosis begins early in life. Infections might contribute to the pathogenesis of atherosclerosis. In this study, we investigated whether acute infections in children could alter the carotid wall morphology and the lipid profile. METHODS: Mean carotid intima-media thickness (IMT) was measured by high-resolution ultrasound in 28 hospitalised children (mean age: 5+/-2 years), who fulfilled the diagnostic criteria of acute infections (body temperature, >38 degrees C; C-reactive protein, >15mg/ml, and clinical), and in 20 age- and gender-matched controls. Antibodies against oxidised low-density lipoprotein (anti-oxLDL antibodies), as well as total and high-density lipoprotein cholesterol (HDL-C) were analysed in all children. The infection group was investigated both during the acute illness and 3 months after clinical recovery (post-infection). RESULTS: During the acute illness, the infection group had elevated anti-oxLDL antibodies and decreased HDL-C, as compared to those obtained at 3 months and in controls (p<0.05). These changes in the infection group were followed, at 3 months, by thickening of carotid intima-media. Those who received antibiotics during their acute illness had less carotid thickening than those who were not treated with antibiotics (p<0.05). CONCLUSION: Acute infections in children seem to be accompanied by enhanced oxidative modification of LDL and by decrease in HDL-C. These lipid changes may be followed by thickening of carotid artery intima-media. These findings suggest that, in childhood, acute infections could be associated with increased risk of atherosclerosis, and warrant further studies on this topic.     

床旁临时起搏器作为AMI的常备急救设备及其在基层医院推广应用研究

目的 床旁临时起搏器作为急性心肌梗死（AMI）的常备急救设备的价值及其在基层医院推广应用的可行性研究。方法 回顾性研究分析2001-2003年间不能床旁植入临时起搏器与2004-2005年能床旁植入临床起搏器抢救AMI的住院病死率、心衰、心源性休克、2mo后再次住院发生率。临时起搏器植入术安全性的指标比较。结果 不能床旁植入临时起搏器组的住院病死率为14．58％，心衰发生率为27．08％，心源性休克发生率为12．5％，2mo后再次住院发生率为16．67％。床旁植入临时起搏器组的住院病死率为3．57％，心衰发生率为7．14％，心源性休克发生率为3．57％，2mo后再次住院发生率为3．57％，两组相比p〈0．01有显著性差异。而起搏器植入的安全性指标：起搏器植入成功率为100％，脱位率为10．7％，并发症发生率为14.3％，住院病死率3．57％。结论 床旁临时起搏器抢救AMI住院病死率低，心衰发生率、心源性休克发生率及2mo后再次住院发生率低，应作为AMI抢救的常备急救设备，另外床旁临时起搏器植入是安全的、有效的，成功率高，操作不难，在基层医院（二甲医院）可推广应用。

Acute Cellular Rejection Predominated by Monocytes Is a Severe Form of Rejection in Human Renal Recipients With or Without Campath-1H (Alemtuzumab) Induction Therapy

Campath-1H has been used successfully for induction and has resulted in a low rate of acute cellular rejection (ACR) in renal transplantation in combination with various postoperative immunosuppression regimens. This study was undertaken to investigate the extent of monocyte involvement in ACR, with or without Campath-1H induction. We found that monocytes represented the majority of inflammatory cells in grades Ib or higher ACR, but not with Ia type of ACR, regardless of the status of Campath-1H induction. Cases of ACR, following Campath-1H induction, appear to demonstrate a 'pure form' of monocytic ACR, whereas monocytes were mixed with many other types of inflammatory cells in the cases of ACR in the absence of Campath-1H induction. In addition with Campath-1H induction, the cases of monocyte-predominant ACR were found to uniformly exhibit a good response to corticosteroid treatment. We conclude that monocyte-predominate ACR may represent a severe form of rejection, with or without Campath-1H treatment.

晕得宁毒性的实验研究

晕得宁为复方中药制剂,济宁市第一人民医院耳科用于治疗美尼尔氏病疗效良好,我室对此方剂进行了毒理学研究。急性毒性实验表明,小鼠一次灌胃量达人用量的200倍(n=10),观察72小时,未见异常表现及死亡。亚急性毒性实验:实验组12只家兔(分成大、中、小剂量三组),连续给药三周,其观察指标包括体重、血常规、肝功(GPT)和肾功(BUN),与对照组(n=4)相比,均无异常(P>0.05);病理检查10兔正常,另2兔患有肺炎。其中1只病兔属大剂量组,于给药第20～21天出现腹泻并死亡,可能与方剂组成中半夏的毒性有关。作者认为晕得宁的毒性较小;鉴于半夏有毒,临床用药宜避免大剂量、长期应用。     

闭合型双循环生物人工肝支持系统治疗犬急性肝功能衰竭实验研究

目的探讨和评价闭合型双循环生物人工肝支持系统(CBC-BALSS)在治疗犬急性肝功能衰竭模型过程中的稳定性、安全性和有效性。方法建立犬急性肝功能衰竭模型(门腔分流联合胆总管离断),采用CBC-BALSS进行支持治疗。20只模型犬分为两组CBC-BALSS治疗组(n=11);无肝细胞CBC-BALSS对照组(n=9)。治疗时限6h。检测实验犬血氨、生化全套、凝血因子(FactorⅦ)、支/芳氨基酸(BCAA/AAA)、单乙基甘氨酸二甲苯胺(monoethylglycinexylidide,MEGX)和细胞循环路生化全套、肝细胞密度和数量。结果CBC-BALSS细胞回路细胞悬液总体积200ml,肝细胞的总数1×1010个、密度5×107/ml、活率98%左右。治疗中16只犬的生命体征平稳,在治疗30min内均出现一过性低血压;2只转流开始15min出现过敏反应;1只转流中因上消化道出血死亡;1只因穿刺部位出血死亡。模型治疗前血氨、ALT、TBil/DBil、白蛋白、FactorⅦ和BCAA/AAA分别达150mmol/L、400U/L、80/55mmol/L、35g/L、20%和1.6;CBC-BALSS治疗6h后,血氨、TBil/DBil下降均显著低于对照组;ALT存在下降趋势且在第6小时差异有统计学意义;白蛋白、FactorⅦ和BCAA/AAA在所有时段、组间差异均无统计学意义。在治疗1h和2h,MEGX差异有统计学意义,治疗组MEGX比对照组提前2h达最高点。治疗15~30min后,双循环路压力至115mmHg趋于平稳,且在±5mmHg波动。在治疗过程中,治疗组细胞循环路ALT显著性升高;组间细胞循环路TBil/DBil变化差异无统计学意义,而两组在各时间点均显著性升高;白蛋白变化无统计学意义。结论CBC-BALSS治疗犬急性肝功能衰竭过程中,安全、有效、稳定且代谢支持作用明显。     

Sustained low-grade pro-inflammatory state in unmedicated, remitted women with major depressive disorder as evidenced by elevated serum levels of the acute phase proteins C-reactive protein and serum amyloid A.

BACKGROUND: Major depressive disorder (MDD) shows increased coronary artery disease (CAD) risk of unknown mechanism(s). MDD is more common in women than men; CAD diagnosis can be difficult in women. Elevations of the inflammatory markers C-reactive protein (CRP) and serum amyloid A (SAA) predict increased CAD risk in populations; few data on these markers exist in MDD, particularly in remitted patients. METHODS: We measured fasting am serum CRP (high sensitivity, CRP(hs)) and SAA in 18 unmedicated, remitted women with MDD (mean age 41 +/- (SD)12, body mass index (BMI) 25.2 +/- 4.1 kg/m(2)) and 18 BMI-matched healthy control subjects (age 36 +/- 10, BMI 25.3 +/- 3.8 kg/m(2)) on 2 separate occasions, > or = 6 days apart. RESULTS: Repeat SAA and CRP(hs) measurements strongly correlated across study days (SAA: r = .83, p < .001; CRP(hs): r = .94, p < .001). Both SAA (5.30 +/- 3.39 vs. 2.84 +/- 1.87 mg/L, p < .005) and CRP(hs) (3.23 +/- 3.17 vs. 1.12 +/- 1.45 mg/L; p < .01) were significantly elevated in MDD women versus controls. CONCLUSIONS: Elevated SAA and CRP(hs) in remitted, unmedicated women with MDD indicate a pro-inflammatory state unrelated to current depressive symptoms or pharmacotherapy. These findings suggest that inflammatory mechanisms may in part underlie findings of increased CAD risk in MDD.
