抗神经元抗体对副肿瘤综合征早期诊断的临床意义

目的 探讨抗神经元抗体抗-Hu、抗-Yo、抗-Ri抗体的检测与副肿瘤综合征早期诊断的关系。方法 采用蛋白免疫印迹分析(Western Blot)法对12例确诊为副肿瘤综合症(PNS)的患者血清及32例非PNS血清进行检测。结果 12例确诊患者血清中检测到一项或多项抗体阳性;PNS患者血清中抗-Hu、抗-Yo、抗-Ri抗体的阳性率高于非PNS对照组,差异有极显著性意义(P<0.01);正常对照组血清抗-Hu,抗-Yo,抗-Ri抗体全部为阴性。结论 抗神经元抗体抗-Hu、抗-Yo、抗-Ri抗体可作为PNS早期诊断及确诊的指标。     

Sonographic diagnosis of early recurrence after inguinal herniorrhaphy: Potential pitfalls

Three patients who presented with scrotal swelling within a few days of inguinal herniorrhaphy are reported. Ultrasonography scans performed in these patients all demonstrated features suspicious of recurrence of hernia. One patient underwent surgical exploration, which revealed only a scrotal haematoma without evidence of recurrent hernia. The other two patients were managed conservatively because clinically the swellings were regarded to be more compatible with haematoma. Both patients had subsequent resolution of the scrotal swelling with no clinical evidence of recurrence of hernia on follow‐up. It is concluded that sonographic diagnosis of recurrence of hernia shortly after inguinal herniorrhaphy can occasionally be misleading.     

Long-term effectiveness and quality of life improvement in entacapone-treated Parkinson's disease patients: the effects of an early therapeutic intervention

To evaluate the long-term effects of entacapone on both mean daily 'on' time and health-related quality of life (QoL) in patients with Parkinson's disease (PD) experiencing 'end-of-dose' motor fluctuations and the benefits of an early therapeutic intervention. A prospective, multicenter, observational, 12-month study was performed with an initial 3-month intervention phase, consisting of a phone call to half of the patients from randomly selected investigators to assess if dose adjustment was necessary. Effectiveness was determined by home diaries ('on' time), subscales II and III of the Unified Parkinson's Disease Rating Scale (UPDRS), and the Parkinson's Disease Questionnaire (PDQ-8). After 3 months of treatment, 4.0% of the intervention group patients discontinued the study, versus 18.4% in the control group ( P  < 0.01). The improvement in 'on' time was significantly increased since the 3-month visit (21%, P  < 0.0001) until the end of the study (23% at 12 months, P  < 0.0001). Entacapone also induced significant reductions in the UPDRS scores for subscales II and III and in the PDQ-8 score. 11.2% of patients experienced at least one adverse reaction. This study confirms the effectiveness of entacapone in reducing motor fluctuations by increasing 'on' time, and in improving QoL of PD patients. An early adjustment of entacapone and levodopa doses reduces the number of treatment discontinuations during the first months of treatment.     

重症急性胰腺炎早期治疗的探讨及分析

目的 探讨重症急性胰腺炎（SAP）早期治疗体会及外科手术治疗时机和手术方式的选择。方法 对比分析1989—1995年以早期手术为主的36例SAP（A组）与1996—2003年7年中非手术治疗为主的44例SAP（B组）的治愈率和死亡率。结果 B组的死亡率明显低于A组，A组的治愈率低于B组。结论 SAP早期的急性炎症反应期，手术只能加重对机体的打击，加重SAP全身炎症反应，增加手术死亡率。故SAP早期治疗应以非手术疗法为主。当内科治疗无效，手术治疗是唯一的选择，而手术时机的掌握和手术方式的选择更为重要，直接影响手术结果。     

Disorders in early embryonal cellular proliferative properties distort the postnatal formation of nervous, immune, and endocrine regulation systems in a newborn

Disorders in the postnatal nervous, immune, and endocrine regulation systems were revealed in the progeny of rats irradiated during the preimplantation period of embryogenesis. These disorders persist till adult age. The direction of disorders confirms the hypothesis about memorization of changed proliferative properties of embryonal cells during the development of the (pro)endocrine system of a new organism. Memorization results in distortion of postnatal nervous immunoendocrine regulation: hypertrophy of the endocrine component and coadaptive underdevelopment of the nervous and immune components.

腹腔镜在异位妊娠中的诊断和治疗价值

本文分析1982～1987年间收治的544例异位妊娠,其中270例行腹腔镜检查、274例未作腹腔镜检查。两组资料相比提示:腹腔镜检查组诊断符合率高达97.40％;由于能及早明确诊断,故该组腹腔内出血量比未作腹腔镜检查组少,平均为241m1/372ml(P<0.05),需输血例数明显减少30例(11.11％)/134例(48.90％)(P<0.01),输卵管未破裂者增高222例(82.22％)/194例(70.80％)(P<0.01)。270例无术后并发症发生。上述给年轻不孕患者作非手术治疗或输卵管保守手术以保留生育功能提供良好条件。

Deprivation of parenting disrupts development of homeostatic and reward systems in marmoset monkey offspring.

BACKGROUND: Early environment is a major determinant of long-term mental health, evidenced by the relationship between early-life neglect or abuse and chronically increased vulnerability to developmental psychopathology, including major depressive disorder (MDD). Animal studies can increase understanding of environmentally mediated causal risk processes. We describe how daily deprivation of biological parenting in primate infants disrupts development of homeostatic and reward systems central to MDD. METHODS: Nine breeding pairs of marmoset monkeys provided control twins (CON) and early-deprived twins (ED); the latter were socially isolated for 30-120 min/day on days 2-28. During the first year of life, basal urinary norepinephrine (NE) titers and cardiophysiologic activity were measured. At the end of year 1 (adolescence), automated neuropsychologic tests were conducted to measure responsiveness to changes in stimulus-reward association (simple/reversed visual discrimination learning) and to reward per se (progressive ratio [PR] reinforcement schedule). RESULTS: The ED monkeys exhibited increased basal urinary NE titers and increased systolic blood pressure relative to CON siblings. The ED monkeys required more sessions to reinstate stimulus-oriented behavior following reversal, suggesting increased vulnerability to perceived loss of environmental control; ED monkeys also performed less PR operant responses, indicating that reward was less of an incentive and that they were mildly anhedonic relative to CON. CONCLUSIONS: In marmoset monkeys, neglect-like manipulation of ED leads to chronic changes in homeostatic systems, similar to those in children and adolescents exposed to early-life adversity and in MDD, and to responses to environmental stimuli similar to those that characterize MDD.

Early rapid weight gain and current overweight in relation to asthma in adolescents born with very low birth weight

Early catch-up growth and subsequent overweight are suggested to be associated with later cardiovascular diseases and later type II diabetes. However, the impact of early catch-up growth and childhood overweight on the development of asthma has been less studied, particularly in children born with very low birth weight (VLBW). A birth cohort of 74 VLBW children (birth weight < or = 1500 g) was followed from birth and investigated on asthma at 12 yr of age. Early rapid weight gain was in one way defined as an increase of weight > or =1 standard deviation score (SDS) at 6 months of corrected postnatal age. Current overweight was defined by body mass index (BMI) exceeding 21.2 and 21.7 kg/m(2), respectively, for boys and girls at 12 yr of age. Current asthma was diagnosed by a pediatrician, according to asthma ever in combination with a positive response to hypertonic saline bronchial provocation test and/or wheeze at physical examination at 12 yr old. Being overweight at 12 yr of age was associated with an increased risk for current asthma in the VLBW children [crude odds ratio (OR): 5.5, 95% confidence interval (CI): 1.3-22.2]. After adjustment for early weight gain and neonatal risk, the OR of overweight increased nearly three times (adjusted OR: 15.3, 95% CI: 2.5-90.6). Early rapid weight gain seemed to be inversely associated with current asthma (adjusted OR: 0.49 for an increase of weight equal to 1 SDS, 95% CI: 0.23-1.02, p = 0.06). In addition, early rapid weight gain was inversely associated with the magnitude of bronchial responsiveness at 12 yr (coefficient -1.15, p < 0.01). There was a strong and positive association between overweight and asthma at 12 yr of age in the VLBW children. This strong association had been reduced by early rapid weight gain, possibly via the reduction of bronchial responsiveness.
