水稻亚种间杂种优势利用研究

本试验探讨了华南双季稻区利用亚种同杂种优势的特点和问题,结果表明:当前,两系亚种问杂种一代主要存在的问题是结实率低和谷草比低;籼粳交杂种易受环境条件的影响;每穗实粒数和单株有效穗数是决定单株产量的重要因子;每穗实粒数增加的关键在于结实率的提高,本文还就提高结实率和谷草比等问题提出了意见。     

嗜肺军团菌聚合酶链反应检测方法及其应用研究

根据嗜肺军团菌基因组ＤＮＡ的种特异性ＤＮＡ片段序列，合成一对引物进行聚合酶链反应（ＰＣＲ）。经琼脂糖凝胶电泳、ＥＢ染色结果表明，一条８７０ｂｐ的核苷酸区带为嗜肺军团菌１～１４血清型菌株所共有。ＰＣＲ检测水中军团菌，其敏感性为３５０ｃｆｕ／ｍｌ，而用同位素标记探针、斑点杂交法检测，其敏感性为４３ｃｆｕ／ｍｌ。ＰＣＲ检测人工感染嗜肺军团菌的豚鼠组织标本，阳性率为８３．３％，而细菌分离培养的阳性率仅为２６．６％。在现场调查中，用ＰＣＲ法初步验证了一起由Ｌｐ１０引起的军团菌病爆发。上述结果表明，ＰＣＲ法能快速、敏感、特异性检测嗜肺军团菌感染。     

Acute repetitive giratory seizures as a manifestation of nonketotic hyperglycemia]

This 71 years old women without any history of epilepsy had diabetes mellitus. She was admitted for repetitive giratory seizures in relation with non-ketotic hyperglycaemia. The EEG showed right centro-parietal paroxysmal slow activity. Symptomatology disappeared within 48 hours after insulin therapy. One month later, she presented with a left hemiplegia in relation with a right sylvian infraction. The role of focal transitory ischaemia in connection with hyperglycaemia is discussed.

孤立性左肝胆管结石并肝管狭窄的外科治疗

目的总结近２０年来孤立性左肝胆管结石并发左肝胆管狭窄的临床治疗体会．方法原发性肝胆管结石１０１８例，年龄２７～７２岁，其中孤立性左肝胆管结石１３３例，手术治疗１１２例，对其临床资料进行回顾性分析，包括各肝管狭窄并发率，术前各项检查确诊率，手术治疗方式，再狭窄率．结果左肝管狭窄的发生率为５９８％，左外肝管和左内肝管分别为８４０％和８４８％，均以重度狭窄为主．狭窄切开整形后高位胆肠吻合术是处理左肝管狭窄的常用手术方式（５２２％），远期再狭窄率为１７１％；左半肝切除术施实率为１９４％，再狭窄率为００％；狭窄整形术和狭窄扩张术的施实率分别为９０％和１９４％，再狭窄率分别为５００％和９２３％．左外肝管狭窄通常采用肝段或肝叶切除术（７８７％），而左内肝管狭窄的处理则通常采用非左半肝切除术（８４８％）．左内肝管狭窄的术前／后影像学确诊率明显低于左肝管和左外肝管，平均确诊率依次２５９％，９３３％和８７９％．结论二级肝管狭窄是孤立性左肝管结石的常见并发症，肝叶或肝段切除术是其首选治疗原则．过多依赖非肝叶／段切除术和不适当的肝段切除术是遗留狭窄和远期疗效差的重要原因     

Hyperexcitability associated with localizable lesions in epileptic patients

Intracellular recordings from neurons were carried out in cortical slices obtained from tissue removed from patients suffering from intractable seizures. The patients were divided into two groups based on the presence or absence of an anatomical abnormality that could be imaged preoperatively. The lesion or its surround was the presumptive epileptogenic area. The tissue removed from the patients without lesions was removed either for biopsy purposes or for access to epileptic tissue and was not considered epileptogenic. All neurons from patients without an imageable lesion, and some (19%) from patients with an imageable lesion, responded to orthodromic stimuli with a sequence of synaptic excitation followed by inhibition; these properties resembled those of normal rodent cortical slices. Different responses, classified as abnormal, were observed in 81% of the neurons in tissue specimens obtained near lesions. The most common was prolonged synaptic excitation with no noticeable inhibition, even at high stimulus strengths. In three resections, long latency all-or-none depolarization shifts were observed that resemble the classic paradoxical depolarization shift seen in in vivo extracellular recordings. Loss of specific inhibitory systems within the cortex may contribute in part to these abnormal responses.

Modeling two dimensions of patient satisfaction: a panel study.

Measurement of patient satisfaction is an essential part of health outcome assessment. The purpose of this study is (a) to compare the stability of an aggregate summary measure and two separate summary measures of patient satisfaction; and, (b) to examine causal effects between two separate summary measures at two points in time. Data were collected from 1,451 Medicare HMO beneficiaries. In conclusion, (a) separate summary measures are recommended for constructing the measure of patient satisfaction and (b) moderate causal relationships and cross-lagged effects between the patient satisfaction measures of qualify of care and access to care were found.     

美宝湿润烧伤膏在治疗慢性泪囊炎的应用

目的：观察美宝湿润烧伤膏(MEBO)在治疗慢性泪囊炎的应用价值。方法：对87例102只慢性泪囊炎采用泪道探通手术与MEBO置留治疗。常规泪点表面麻醉，扩张泪点，用生理盐水或氯霉素眼水冲洗鼻泪管、泪囊、泪小管，再用无菌注射器装入5ml MEBO，用5号自制泪道冲洗针沿泪道方向插入，直达泪囊推药，使鼻泪管、泪囊、泪小管内充满MEBO，一周后继续上述方法治疗，一般连续治疗2—5次。结果：治疗总有效率为100％，随访6个月，无一例复发。结论：在泪道探通手术后随即留置MEBO治疗慢性泪囊炎，临床效果良好，操作简单方便，经济有效，值得临床推广应用。
