继发性甲旁亢的锁骨骨吸收

１８例慢性肾衰继发性甲旁亢病人发现有锁骨骨吸收。发病部位包括锁骨内端、外端、外１／３下缘及内段下缘４个部位。其中锁骨内、外端骨吸收属软骨下骨吸收，内、外段下缘骨吸收属韧带下骨吸收。作者对锁骨骨吸收的Ｘ线表现及发病机制作了讨论。认为锁骨骨吸收是继发性甲旁亢的重要Ｘ线征象，对诊断肾性骨病具有重要的意义。     

有机药物化学中不对称合成手性产率及其随温度变化规律的研究

本文首次用分子力学计算产物或过渡态分子内张力能来估算热力学或动力学,控制不对称合成反应生成的立体异构体的相对比例,并从热力学上推导了这一比例随温度变化公式,而且从实验上得到证明,在有机或药物化学最富有挑战性的领域——不对称合成中具有重要的理论和实际意义。     

Low sodium content formula for infants with congestive heart failure

Twenty-two infants of isolated ventricular septal defect with congestive heart failure were fed with lower-sodium content formula-Lonalac (Mead-Johnson) to study the clinical response of treatment for congestive heart failure. There were no significant changes of intake, urinary output, serum sodium, potassium and osmolality before, 2 days and 6 days after Lonalac feeding. The low sodium content formula may feed the infants with congestive heart failure in addition to the traditional anticongestive therapy.     

海口地区2000年临床分离菌耐药性监测

目的：监测海口地区临床分离菌对抗菌药物的耐药状况。方法：采用VITEK微生物自动分析仪测定药敏。结果：2000年共收集临床分离菌1399株，革兰阳性球菌426株（30．5％），革兰阴性杆菌973株（69．5％），以铜绿假单胞菌、大肠杆菌、金黄色葡萄球菌、肺炎克雷伯杆菌最多见，所监测的细菌总体耐药率比国内其他地区偏高，且出现万古霉素耐药的表皮葡萄球菌和粪肠球菌。结论：海口地区的细菌耐药严重，控制细菌耐药成为当务之急。     

深低温停循环逆行脑灌注脑组织自由基变化的实验研究

研究深低温停循环（ＤＨＣＡ）与逆行脑灌注（ＲＣＰ）时脑组织自由基的变化。健康杂种犬１４只，随机等分为ＤＨＣＡ组和ＲＣＰ组，在停循环前（Ａ点）、ＤＨＣＡ／ＲＣＰ３０分（Ｂ点）、ＤＨＣＡ／ＲＣＰ６０分（Ｃ点）ＤＨＣＡ／ＲＣＰ９０分（Ｄ眯）和复温再灌注３０分（Ｅ点）取脑皮层ｌｇ，检测丙二醛（ＭＤＡ）和超氧化物歧化酶（ＳＯＤ）水平。结果见两组在Ａ点ＭＤＡ和ＳＯＤ无差别。在Ｂ、Ｃ、Ｄ、Ｅ点，ＤＨＣＡ组ＭＤＡ     

大鼠肝细胞Ⅰ，Ⅲ型前胶原基因表达及PDGF的影响

目的观察大鼠肝细胞Ⅰ，Ⅲ型前胶原基因的表达及ＰＤＧＦ对其表达的影响．方法应用原位杂交技术检测分离培养的ＳＤ大鼠肝细胞（ｎ＝３０）内Ⅰ，Ⅲ型前胶原基因的表达．同时观察１０μｇ／Ｌ（ｎ＝３０）和３０μｇ／Ｌ（ｎ＝３０）ＰＤＧＦ促进前胶原基因表达的作用．测定基因表达颗粒总面积占细胞总面积的百分比，并作比较分析．结果无论正常肝细胞或是在两种浓度的ＰＤＧＦ存在时，肝细胞内均可见到Ⅰ，Ⅲ型前胶原基因的表达．正常肝细胞Ⅰ，Ⅲ型前胶原基因表达面积的百分比（％）为７７±１９和７５±２１；加１０μｇ／ＬＰＤＧＦ后为１１５±１９和１１２±１０，而加３０μｇ／Ｌ后为１５２±３４及１８１±２８，且在后者中表达明显增强（Ｐ＜００５及Ｐ＜００１）．结论ＰＤＧＦ在转录水平上促进肝细胞胶原的合成．     

CT造影剂碘海醇注射液的制备及动物实验

本文报道了非离子型Ｘ－ＣＴ造影剂碘海醇注射液的制备及动物实验结果。磺海醇的最大吸收波长λ＿（ｍａｘ）为２４４ｎｍ。讨论了温度、浓度对磺海醇溶液粘度的影响：粘度随温度的升高而下降，呈负线型相关；粘度随浓度（Ｃ）升高而激剧升高，与浓度的四次方呈线性相关：Ｖ＿（３７℃）＝４７２．５８９［Ｃ］￣４＋１．１２１（ｒ＝０．９９７７）Ｖ＿（３０℃）＝６６３．８１３［Ｃ］￣４＋１．１５２（ｒ＝０．９９９６）Ｖ＿（２０℃）＝１０８２．９５３［Ｃ］￣４＋１．４３３（ｒ＝０．９９８２）使用该注射液进行狗的造影实验，获得了清晰的造影图像。     

大气中不同粒径颗粒物诱导人羊膜FL细胞UDS的研究

本研究以诱导人羊膜细胞ＵＤＳ为指标，对太原市大气不同粒径的颗粒物提取液进行了致突变性检验，结果表明，不同粒径颗粒物的提取液均可产生一定的遗传毒性，尤以３．３μｍ以下的颗粒物的遗传毒性较强。     

Clinical and experimental study of xiao er ke cuan ling oral liquid in the treatment of infantile bronchopneumonia]

Xiao Er Ke Chuan Ling Oral Liquid (KCL) is a Chinese herbal preparation consisted of 10 herbs such as Prunus armeniacae, Scutelaria baicalensis, Lonicera japonica etc. 30 children suffering from bronchopneumonia and/or acute bronchitis were treated with KCL (treated group) and another 30 cases were treated with penicillin and aminophylline (control group). Results: cure rate and effective rate in treated group was 26.6%, and 93.3% respectively. While in control group was 30% and 96.6% respectively. No significant differences were seen between them(P > 0.05). The pharmacodynamic experiment showed KCL had potent pharmacological action. The experiment on tracheal fragment of Guinea pig in vitro showed it caused moderately strong smooth muscle relaxation, through inhibition the effect of histamine and acetylcholine. Asthma induction experiment of Guinea pig in vivo showed KCL could significantly prolong the latent period of asthma and alleviate asthmatic symptom. Ammonium water cough induction experiment in mice showed it may apparently prolong cough latent period and reduce times of cough relapse and alleviate cough symptom. KCL had potent antipyretic effect on fever model induced by triple vaccine in rabbits. Bacteriostatic and antiviral experiment in vitro showed the drug had quite strong inhibitory effects for Streptococcus hemolyticus, Staphylococcus aureus, Flexners Dysentery bacillus, Diplococcus pneumoniae and Pseudomonas aeruginosa, and it could potently inhibit the respiratory syncytial virus. KCL is an effective drug in treating bronchopneumonia and acute bronchitis.
