A prospective study of the association of cerebrospinal fluid monoamine metabolite levels with lethality of suicide attempts in patients with bipolar disorder

Objectives:  Bipolar disorder is a severe illness that is associated with suicidal behavior. A biological predictor of highly lethal suicide attempts in patients with bipolar disorder would be valuable. We hypothesized that cerebrospinal fluid (CSF) monoamine metabolite levels are related to lethality of suicide attempts in bipolar patients and examined the relation between CSF 5-hydroxyindolacetic acid (5-HIAA), homovanillic acid (HVA), and 3-methoxy-4-hydroxyphenylglycol (MHPG) levels and maximum lethality of suicide attempts at baseline and during a 2-year follow up.
Methods:  Twenty-seven bipolar depressed patients participated in the study. Demographic and clinical parameters were examined and recorded. Lumbar punctures were performed and CSF 5-HIAA, HVA, and MHPG were assayed by high-performance liquid chromatography with electrochemical detection. Following discharge, patients were evaluated after 3 months, 1 year, and 2 years. Each follow-up interview included an in-depth assessment of suicidal behavior during the intervening time period.
Results:  Six subjects made suicide attempts during the 2-year follow-up. Bipolar patients who attempted suicide during the follow-up period had higher aggression and hostility scale scores compared to bipolar subjects who did not make a suicide attempt during the follow-up period. CSF 5-HIAA, HVA, and MHPG levels were negatively correlated with the maximum lethality of suicide attempts during the 2-year follow-up period.
Conclusions:  Our finding is the first observation that CSF monoamine metabolite levels may be predictors of lethality of suicide attempts in patients with bipolar disorder. Further studies are necessary to answer the question whether CSF monoamine metabolite levels are clinically useful biochemical predictors of highly lethal suicide attempts or completed suicides.     

齐墩果酸免疫治疗恶性肿瘤病人的临床Ⅱ期研究

前瞻性双盲法临床研究,可评价的恶性肿瘤病人28例,口服齐墩果酸40mg,每日3次,1个月后测定吞噬细胞百分比,由54.1％提高至67.42％。吞噬指数由0.69提高至0.81。迟发超敏反应1:1000浓度转阳性率52.6％(10/19)。E-玫瑰花结试验在本组试验前后无显著变化。同期服用安慰剂的9例对照病人则无变化。治疗后齐墩果酸对骨髓、肝、肾功能均无影响,故可做为比较理想的生物反应调节剂应用于临床,以促进病人的免疫功能。     

小儿氨基酸注射液治疗胎儿宫内发育迟缓的探讨

经临床鉴定静脉内注射小儿氨基酸对治疗胎儿宫内发育迟缓具有肯定效果。在Ｂ超监视下，使用小儿氨基酸的孕妇组于用药期间，胎儿生长参数ＢＰＤ和ＨＣ显著高于使用成人氨基酸的孕妇组。１０例足月娩出胎儿体重均达到甚至超过２．５ｋｇ。由此得出结论：使用小儿氨基酸注射液对于改善胎儿宫内发育迟缓优于成人氨基酸。     

舒必利治疗精神分裂症患者脑脊液HVA含量的对照研究

为了探讨精神分裂症患者治疗期间多巴胺的变化,我们选择舒必利治疗组20例,非舒必利治疗组10例作为病例组;15例非精神病患者作为对照组;检测脑脊液中多巴胺代谢产物高香草酸的含量;结果显示两组无显著性差异。精神分裂症患者治疗后舒必利组高香草酸含量升高,非舒必利组则降低,进一步分析显示舒必利治疗组非显效者较显效者治疗后高香草酸显著升高。提示机体对药物阻滞多巴胺受体后代偿反应的强弱与疗效有一定关系。     

Testicular seminoma with human chorionic gonadotropin production

Testicular seminoma with elevated serum human chorionic gonadotropin level (hCG-positive seminoma) is regarded as more malignant than marker-negative seminoma, although Its prognosis is still unclear. To clarify the malignant potential of seminoma with hCG production, the serum levels of the beta subunit of hCG (β-hCG) and lactic acid dehydrogenase (LDH) were examined in 35 and 40 patients, respectively, and the Immunohistochemical expression of β-hCG examined in 45 tumors. The elevation of the LDH serum level correlated to the Invasive status, metestatic status and poor outcome, while that of the serum β-hCG level correlated only to the metastatic status. Immunohistochemical expression of β-hCG was observed in syncytiotrophoblastic giant cells in 11 tumors and a few mononuclear seminoma cells In 36 tumors. Expression was not associated with the malignancy potential, except where the expression In mononuclear cells Inversely correlated to the invasive status. These results suggest that most seminomas produce a slight amount of hCG; that an elevated hCG serum level Indicates the pressnce of metastatic tumors and mainly reflects an increase in tumor volume but not in cellular malignancy potential; and that the LDH serum level, rather than hCG, is more useful as a prognostic indicator for patients with seminoma.     

L—NAME促进大鼠红藻氨酸诱导性发作

为证明癫痫发作早期一氧化氮（ＮＯ）抗发作效应，用ＮＯ合酶（ＮＯＳ）抑制剂Ｌ－硝基精氨酸甲酯（Ｌ－ＮＡＭＥ）对大鼠红藻氨酸（ＫＡ）诱导性发作进行干预，同时用分光光度法检测海马结构中ＮＯＳ活性的早期变化。发现ＫＡ发作１０ｍｉｎ、３０ｍｉｎ组海马结构中ＮＯＳ活性明显升高，而ＫＡ注射前３０ｍｉｎ给予Ｌ－ＮＡＭＥ可显著抑制ＮＯＳ活性的升高，这种抑制效应与大鼠ＫＡ发作中湿狗样摇动（ＷＤＳ）的提早出现和发生次数增多显著相关。结果提示在ＫＡ诱导大鼠发作早期内源性ＮＯ具有明显的抗发作效用。     

The effect of preconceptional multivitamin supplementation on the menstrual cycle

The database of the Hungarian randomised controlled trial of periconceptional multivitamin supplementation for the prevention of neural-tube defects was used to evaluate the length of the pre- and postovulatory phases of the menstrual cycle before and during multivitamin supplementation. The female cycle was more regular (i.e., the variance was lower) during the multivitamin supplementation.     

三种氨基酸对兔血浆皮质酮浓度的影响

侧脑室注射甘氨酸使健康家兔和烧伤家兔血浆皮质酮浓度降低;注射L—谷氨酸和L—天冬氨酸使健康家兔血浆皮质酮浓度升高,但不能使烧伤后升高的血浆皮质酮浓度发生改变。提示这三种氨基酸作为神经递质参与下丘脑—垂体—肾上腺皮质轴的调控。烧伤刺激通过下丘脑引起内分泌紊乱,这种紊乱与L—谷氨酸和L—天冬氨酸失控有关。     

刺激视上核对大鼠痛阈及电针镇痛的影响

以钾离子透引起的大鼠甩尾反应为痛指标，观察了电和化学刺激视上核（ＳＯＮ）对大鼠痛阈（ＰＴ）和电针（ＥＡ）镇痛的影响。电刺激ＳＯＮ后，ＰＴ明显高于假刺激组（Ｐ＜０．０５～０．００１），电刺激ＳＯＮ后电针足三里，镇痛效应明显提高，并有明显的量效关系。电刺激ＳＯＮ的近旁部位（０．５—１ｍｍ）对ＰＴ及电针镇痛无明显影响。ＳＯＮ内注射Ｌ－谷氨酸（Ｌ－Ｇｌｕ）后痛阈和电针镇痛效应都明显对照组，也有明显的量效关
