利培酮对精神分裂症首次发病患者血清脑源性神经营养因子水平的影响

目的：探讨利培酮对首发精神分裂症患者血清脑源性神经营养因子（BDNF）水平的影响。方法：采用酶联免疫吸附法测定40例首发精神分裂症患者（患者组）在给予利培酮治疗前和治疗8周后的血清BDNF水平,并与40名正常人（正常对照组）的血清BDNF水平进行比较。结果：治疗前患者组血清BDNF水平显著低于正常对照组（P〈0．05）,治疗8周,患者组血清BDNF水平较治疗前明显升高（P〈0．01）;与正常对照组差异无统计学意义（P〉0．05）。患者组中有阳性家族史者（8例）与阴性家族史者（32例）之间血清BDNF水平差异无统计学意义（P〉0．05）。患者组治疗前后血清BDNF水平与阳性与阴性症状量表评分（r=0．283,r=0．09;P〉0．05）无显著相关;两组血清BDNF水平与年龄（r=-0．142,r=-0．122;P〉0．05）、体质量指数（r=-0．112,r=0．039;P〉0．05）均无显著相关。结论：首发精神分裂症患者可能存在血清BDNF水平低下,利培酮治疗可提高其血清BDNF水平。     

偏头痛患者血清肿瘤坏死因子的检测及其意义

通过检测偏头痛患者血清中肿瘤坏死因子α（tumornecrosisfac－tor－α,TNF－α）的含量,探讨其与偏头痛发病的关系。方法　50例病程1年以上、无用激素及免疫抑制剂的偏头痛患者和20例神经衰弱患者及20名正常对照者抽血后,用放射免疫分析法测定血清中TNF－α的含量。结果　　偏头痛患者血清中TNF－α水平显著高于神经衰弱患者（P＜0．01）及正常对照组（P＜0．01）;偏头痛患者发作期血清TNF－α水平高于间歇期（P＜0．05）;有先兆偏头痛患者与无先兆患者血清TNF－α水平差别不显著（P＞0．05）;女性偏头痛患者血清TNF－α水平高于男性（P＜0．05）;不同年龄段患者血清TNF－α水平无差别（P＞0．05）。结论TNF－α与偏头痛发病有关系,可能是引起偏头痛发作的原因。     

性激素与脑梗死的初步研究

目的 探讨性激素失衡与脑梗死（CI）的关系及其引起CI可能的机制。方法 采用放射免疫法测定52例急性CI患者及35名健康对照者的血清性激素水平;并对其中26例CI恢复期患者的性激素进行复查;采用沉淀飘浮酶联法及乙酰丙酮显色法测定两组血脂。结果 CI患者急性期、恢复期男性雌二醇（E2）、E2／睾酮（T）比值明显高于对照组男性（P＜0．01、P＜0．05）,急性期、恢复期女性E2明显低于对照组女性（P＜0．01、P＜0．05）,此改变与病情轻重无关。CI组血清TC、LDL－C显著高于对照组;HDL－C、HDL2－C显著低于对照组。男性患者E2、E2／T比值与TC、LDL－C呈正相关（P＜0．05）,与HDL－C、HDL2－C、HDL3－C呈负相关（P＜0．01、P＜0．05）;女性患者E2与TC、LDL－C呈负相关（P＜0．05、P＜0．01）,与HDL－C、HDL2－C呈正相关（P＜0．01）。结论 CI急性期男性E2、E2／T比值升高,女性E2水平降低。CI的发病机制之一是血脂代谢紊乱,从而引起动脉粥样梗化。

偏头痛患者血清镁水平的变化及其意义

对78例偏头痛患者和21例正常健康人对照的血清镁离子的测定，结果发现偏头痛患者发作期血清镁水平为0．82±0．12mmol／L，自然缓解期为0．87±0．12mmol／L，均显著低于正常对照组的0．95±0．14mmol／L（P＜0．01和0．05）；而补镁治疗后缓解或血清镁水平为0．94±0．15mmol／L，显著高于发作期和自然缓解期（P＜0．01和0．05），与正常对照组无差异（P＞0．05）。认为血清镁在偏头痛的发病中起重要作用，以及在发作期补充镁离子可起到良好的治疗和预防作用。

A psychoendocrine study in male paranoid schizophrenics with delusional ideas of homosexual content

The serum prolactin (PRL), luteinizing hormone (LH), testosterone (T) and estradiol (E) levels were investigated in a group of male paranoid schizophrenics with delusional ideas of homosexual content, in a group of male paranoid schizophrenics without delusional ideas of homosexual content, and in a group of healthy, male heterosexual subjects. Only male paranoid schizophrenics with delusional ideas of homosexual content had significantly lower serum PRL values and significantly higher serum E levels than those of the age-matched group of normal, male heterosexual controls; also, these patients tended to have higher (though not to a statistically significant degree) serum LH and T levels than those of normal controls. Findings of this study are discussed within the framework of the possible involvement of endocrine factors in the occurrence of delusional ideas of homosexual content in male patients with paranoid schizophrenia.     

Serum testosterone levels, mental disorders and criminal behaviour.

OBJECTIVE: Although previous studies have revealed an association between androgens and aggression, there is a lack of knowledge of this issue in different mental disorders. METHOD: The associations between serum testosterone levels and criminal behaviour in different mental disorders were examined using data collected from forensic psychiatric male patients (20 schizophrenics and 42 subjects with personality disorders). RESULTS: Male criminals with personality disorders had significantly higher serum levels of total and free testosterone than criminal schizophrenics. Among schizophrenics, total (P=0.01) and free testosterone (P=0.01) declined significantly more with age compared to healthy controls and patients with personality disorders, and also correlated with duration of neuroleptic drug use (r=-0.60, P=0.000 for total and r=-0.46, P=0.0001 for free testosterone). The recidivists with personality disorder had higher total (P=0.04) and free testosterone (P=0.05) levels than non-recidivists with personality disorder. CONCLUSION: Personality disordered criminals with multiple offences had high serum testosterone levels. The low testosterone concentrations among schizophrenics may be due either to long-term use of neuroleptic agents or to the mental illness itself and its possible inhibition of the pituitary-gonadal axis.     

帕罗西汀对首发抑郁症患者治疗前后性激素水平 变化及与疗效的关系

目的 探索抑郁症患者性激素水平和治疗后的变化与治疗效果的关系.方法 收集抑郁症患者60例作为观察组,健康体检的志愿者60例作为对照组,检测患者治疗前后的血清雌二醇、孕酮及睾酮的水平,用汉密尔顿抑郁量表(HAMD)对抑郁患者进行评分,分析抑郁程度与性激素水平之间的相关性.结果 治疗前观察组男性和女性的血清雌二醇水平均低于对照组,男性的孕酮及睾酮水平低于对照组,差异均有统计学意义(P<0.05),女性的孕酮和睾酮水平与对照组差异无统计学意义(P>0.05);治疗后男性和女性患者的血清雌二醇水平高于治疗前,差异有统计学意义(P<0.05),男性患者的睾酮水平高于治疗前,差异有统计学意义(P<0.05),而男性和女性患者孕酮水平及女性患者的睾酮水平与治疗前的差异无统计学意义(P>0.05);治疗后观察组男性和女性患者的孕酮及睾酮水平与对照组之间的差异均无统计学意义(P>0.05),观察组女性患者的血清雌二醇水平与对照组之间的差异无统计学意义(P>0.05),观察组男性患者血清雌二醇水平低于对照组,差异有统计学意义(P<0.05);HAMD减分率与血清雌二醇水平之间呈正相关(r=0.561,P=0.007);而与血清孕酮及睾酮之间无相关性(P>0.05).结论 抑郁症患者血清雌二醇与抑郁症之间呈负相关,睾酮水平的变化可能仅是男性抑郁症患者的一个危险因素.     

cGMP level in idiopathic Parkinson's disease patients with and without cardiovascular disease - A pilot study

We have previously found that average serum cGMP level in unselected patients with Parkinson’s disease (PD), particularly in patients treated with a combination of l-DOPA and the dopamine agonist pergolide mesylate, is markedly higher than that in healthy controls. Here we compared serum cGMP and total testosterone levels between l-DOPA/pergolide mesylate-treated male idiopathic PD patients without and with cardiovascular disease (iPD, n = 10, and iPD-CVD, n = 10, respectively) and age-matched healthy volunteers (n = 10). There was no difference in PD-related disability between the two patient groups as assessed by UPDRS motor score and Hoehn-Yahr staging. Whereas none of the patients showed hypoandrogenemia, PD patients compared to controls revealed significantly lower serum testosterone levels, and iPD-CVD patients showed significantly lower levels than iPD patients. Serum cGMP levels were but moderately while significantly higher in the two groups of PD patients than in the controls, and were the highest in the iPD-CVD group. For all study groups combined, there was a high negative correlation between total testosterone level and cGMP level. Our data indicate that blood total testosterone level is negatively correlated with general health status in PD patients, whereas the reverse is true for blood cGMP level.     

血清尿酸与进行性核上性麻痹的相关性研究

目的探讨血清尿酸与进行性核上性麻痹(PSP)的相关性。方法收集71例PSP患者,选取70例健康人群为对照组。采用两独立样本t检验比较PSP组与健康对照组血清尿酸的差异,比较不同性别、PSP各亚型之间以及各亚型与对照组之间血清尿酸差异,采用Spearman分析PSP血清尿酸与Hoehn-Yahr分期、统一帕金森病(PD)评定量表第Ⅲ部分(UPDRSⅢ)评分及病程的相关性。结果 PSP组UPDRSⅢ评分、PSPRS评分明显高于健康对照组(P0.05)。而PSP组尿酸则明显低于健康对照组(P0.05)。按不同性别比较时,男性PSP组尿酸明显低于女性(P0.01),亦低于男性健康对照组(P0.01)。PSP各亚型尿酸均明显低于健康对照组(P0.05),差异均有统计学意义。Spearman相关分析,HY分期、UPDRSⅢ评分与尿酸呈明显负相关,而病程与尿酸呈显著负相关(P0.01)。结论血清尿酸减低可能与PSP患病相关,尤其是男性患者,血清尿酸越低,PSP患病越严重;尿酸作为抗氧化剂,对PSP患者可能具有一定的保护作用。     

男性痴呆患者血清性激素的变化

目的:观察阿尔茨海默病(AD)和血管性痴呆(VD)男性患者血清性激素及促性腺激素的变化。方法:老年男性共114人,其中AD 3 2例;VD 3 0例;无痴呆正常老年人5 2名。采用化学发光法测定血中黄体生成素(LH )、促卵泡成熟素(FSH)、雌二醇(E2 )、催乳素(PRL)、睾酮(T)的含量,并计算E2 /T的比值。结果:AD组及VD组患者血清T水平较正常对照组低,差别有显著意义(P <0 .0 5 ,P <0 .0 1)。VD组患者血清E2 /T较正常对照组显著升高;也较AD组明显升高(P <0 .0 1,P <0 .0 5 )。AD、VD组患者血清E2 、LH、FSH、PRL与正常对照组比较,差别均无显著意义(P >0 .0 5 )。结论:老年男性AD及VD患者血清T水平降低。

目的探讨急性一氧化碳中毒后迟发性脑病(DEACMP)患者血清促肾上腺皮质激素释放激素(CRH)水平的变化及其临床意义。方法应用酶联免疫吸附法动态测定33例DEACMP患者血清CRH水平,并与32例急性一氧化碳中毒(ACMP)后未发生DEACMP患者和32例正常对照者进行比较;采用日常生活能力量表(ADL)、常识-记忆-注意测验(IMCT)、长谷川痴呆量表(HDS)动态检查DEACMP患者的病情变化。结果 DEAC-MP组急性期血清CRH水平明显高于正常对照组(P<0.05),与ACMP组急性期比较无显著差异(P>0.05);AC-MP组急性期明显高于正常对照组(P<0.05)。DEACMP组恢复期血清CRH水平明显低于急性期(P<0.05),但仍明显高于ACMP组随访期和正常对照组(均P<0.05);ACMP组随访期血清CRH水平明显低于急性期(P<0.05),与正常对照组比较无显著差异(P>0.05)。DEACMP组急性期ADL、HDS、IMCT评分与恢复期比较均有显著差异(均P<0.05)。DEACMP组急性期、恢复期患者血清CRH水平变化与HDS评分变化之间呈显著正相关性(P<0.05)。结论下丘脑-垂体-肾上腺皮质轴参与了DEACMP的发病机制,CRH的水平变化与病情变化基本一致。

Indolethylamine-N-methyltransferase activity in psychiatric patients and controls.

The level of INMT activity was determined in the sera of 29 psychiatric patients and 11 healthy controls from St. Louis; and in 13 psychiatric patients and 15 healthy controls from Chicago. The level of enzyme activity in the serum of paranoid schizophrenics in the St. Louis group was significantly higher than in other types of schizophrenics. The mean level of enzyme activity in the serum in nonschizophrenic psychiatric patients in the Chicago group was significantly higher than that in the same group of patients from St. Louis. The serum level of INMT activity in all psychiatric patients and schizophrenic patients from St. Louis was positively correlated with severity of delusions. The only significant difference in the Chicago patients was that the occurrence of depressive features was greater in the group of patients with a low serum INMT level than in the group with a high enzyme level.
