Gonadotrophin dynamics during reproductive life.

OBJECTIVE: To evaluate the follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels in early follicular phase throughout the reproductive years. METHOD: FSH and LH concentrations were determined by radioimmunoassay (RIA). Linear and polynomial regressions were carried out considering basal FSH as the dependent and age as the independent variable. RESULTS: FSH levels increased throughout the reproductive years (P<0.025). A positive correlation between age and basal FSH levels was detected (P<0.05). The Pearson squared coefficient of r(2)=0.889 was obtained. Using polynomial regression, the inclination of the parabole (Y=7.97-0.009x+0.057x(2)) was 0.359 and the generalized correlation coefficient was r=0.795. The goodness of fit analysis showed that the parabole may better represent the phenomenon (F=4.7; P<0.05). The LH levels remained constant, increasing only beyond 40 years of age. CONCLUSION: The FSH levels rose in a nonlinear way during the reproductive life and the LH concentrations increased discreetly only in patients over 40 years of age.

内镜激光治疗食管和贲门早期表浅癌疗效及DNA和p53表达与预后关系的研究

目的：研究内镜Ｎｄ：ＹＡＧ激光治疗食管和贲门早期表浅癌的远期疗效和ＤＮＡ及ｐ５３表达与预后的关系。方法：对内镜激光治疗癌细胞消失的３２例食管和贲门早期表浅癌病人进行３３～７８个月（平均５５．３个月）的随访。并与１１７例早期食管癌和贲门癌的自然病程对比分析。应用ＰｒｏｄｕｃｔＬｉｍｉｔＥｓｔｉｍａｔｅ方法计算其存活率。应用免疫组化染色法检测ｐ５３表达。应用分光光度计测定癌细胞ＤＮＡ含量。结果：内镜激光治疗５年存活率为９７％，自然病程５年存活率为６７％（Ｐ＜０．０１）。ｐ５３阳性表达和ＤＮＡ非整倍体型病人的复发率分别为７６．９％和６４．３％。结论：内镜Ｎｄ：ＹＡＧ激光是治疗食管和贲门早期表浅癌的有效方法。抗癌基因ｐ５３和ＤＮＡ倍体数与病人的预后有关。     

早期胃癌的诊治(附15例临床分析)

目的：总结15例早期胃癌临床特点，诊治经验，探讨治疗新进展。方法：对15例早期胃癌诊治进行回顾性总结。结果：早期误诊率达66．7％，15例手术，术后存活5年以上13例（86．7％）。结论：早期胃癌缺乏特异症状，早期误诊率高，内镜下平坦型胃癌最易误诊，作认为D2术应为根治EGC的标准术式，内镜下粘膜切除术（EMR），保留迷走神经胃段切除术有利于保护患术后生存质量。     

Early and late onset bacteremia have different risk factors in trauma patients

Objective The aim of this study was to identify risk factors and to describe epidemiological patterns for early—(EOB) and late—onset bacteremias (LOB) after trauma.Design A prospective study conducted on 141 consecutive trauma patients.Setting A general intensive care unit (ICU) of a university hospital.Patients All multiple trauma patients admitted to our general intensive care unit (ICU) from December 1990 to May 1992 were prospectively enrolled in the study. The following information was collected for each patient and recorded in a computer database: demography, severity of trauma according to the Abbreviated Injury Scale (AIS), severtity of trauma according to the Glasgow Coma Scale (GCS), presence of pneumothorax, pulmonary contusion, rib fractures, hemothorax, and abdominal trauma, use of mechanical ventilation, and placement of central venous catheters. Bacteremias were defined as EOB when onset occurred within 96 h after trauma, and as LOB when appearing after 96 h from trauma.Results Thirty-seven patients developed bacteremia during their ICU stay (26%): 11 (29.7%) EOB and 26 (70.3%) LOB. Gram-positive cocci were isolated more frequently in EOB than in LOB (x ²=4.1,P=0.04). The risk of EOB was significantly increased by the presence of pulmonary contusion [relative risk (RR) 15.0; confidence interval (CI) 1.99-113.25], pneumonia before the onset of bacteremia (RR 3.56; CI 1.17-10.69), AIS score greater than 32 and an abdominal injury score greater than 9 (RR 3.11; CI 1.02-9.49), while intravascular catheters and mechanical ventilation did not represent risk factors for EOB. LOB had a very different pattern and their risk was significantly increased by exposure to intravascular catheters (RR 4.96; CI 1.23-19.94) and to mechanical ventilation lasting more than 7 days (RR 3.6; CI 1.6-8.1).Conclusions Scoring with the AIS of the abdominal and thoracic trauma at admission to the ICU appears a useful tool for identifying trauma patients at increased risk of EOB. A rigorous policy of catheter placement and maintenance as a means of reducing late bacteremias in trauma patients is essential.     

The Effects of Early Childhood Abuse and the Development of Resiliency

Recently, the number of young children who have suffered from the traumas of abuse and neglect has increased. There are negative cognitive, neurological, and psychological effects from this maltreatment which is described in this article. Interventions which can prevent neglect and abuse and further resiliency in the young victims are discussed. As concerned individuals, we need to advocate for preventive and therapeutic efforts which promote resiliency in maltreated children.     

老年人主观认知下降与慢性病共病的相关性分析

The Modality Specificity of the Slow Negative Wave

Event-related potentials were recorded in a simple reaction time task using a 3-sec interval between S₁ and S₂. The sensory modalities of S₁ and S₂ were varied across 4 conditions to yield all possible combinations of tones and flashes. A negative component which peaked between 600 and 800 msec after S₁ was specific in scalp distribution to the modality of S₁ but not S₂. It was concluded that this negative component is a response to S₁ and not related to processes associated with anticipation of S₂. A slow negative shift which peaked at S₂ was largest at the vertex in all conditions, suggesting its motor origin. A trend for the latter activity to be more negative in posterior recordings when S₂ was visual than auditory leaves open the possibility that the terminal CNV is a combination of motor activities and anticipation of the sensory modality of S₂.
