Family system test (FAST): Are parents' and children's family constructs either different or similar,or both?

Perceptions of family cohesion and hierarchy structures were assessed by theFamily System Test (FAST), a clinically-derived figure placement technique. Parents (N=140) and their preadolescent offspring (N=70) completed typical and conflict representations in individual as well as group settings. Typical representations were characterized by balanced family structures (i.e. cohesive and moderately hierarchical) and those displaying conflict situations showed predominantly unbalanced patterns. FAST portrayals were related to respondent (mother vs. father vs. child). Fathers represented typical family relations as balanced more often than mothers. Regarding conflict representations, children were more likely than fathers to portray the family as unbalanced. However, analyses of representations of the same family (i.e. intra-family comparisons) indicated that all respondents differed in their perceptions and, that fathers' typical portrayals showed most often the same structure as those done by the family members as a group.

多发性颅骨内血管瘤一例报告并文献复习

目的探讨多发性颅骨内血管瘤的临床特征和预后。方法报告1例多发性颅骨内血管瘤病例,结合相关文献分析该疾病的X线、CT、MRI和DSA等临床特征,探讨治疗效果和预后。结果多发性颅骨内血管瘤临床上极为罕见,大约占所有骨肿瘤的0.2%。X线平片检查见整个颅骨内蜂窝状改变,CT、MRI显示颅骨溶骨性病变或糜烂并向颅内外发展,DSA造影病变无染色,病理显示大小不等的异常血管,骨结构异常以及出血征象。外科治疗效果不佳。结论多发性颅骨血管瘤为颅骨内破坏性病变,涉及整个颅骨的多发性颅骨血管瘤,外科治疗效果不佳。     

非常见胆道梗阻性或黄疸性疾病的诊治

黄疸作为一个最具警觉的体征，容易诊断。然而发生黄疸的病因繁多，可由肝前性、肝细胞性和梗阻性（包括肝内胆汁淤积和肝外胆道狭窄梗阻）三类疾病引起。对于临床上的黄疸，首先是同步进行诊断和鉴别诊断。如确诊为梗阻性黄疸，因常需采用外科治疗（包括手术及介入方法）而得到根治或缓解，故临床上通常称为外科性黄疸。但并非所有的梗阻性黄疸均需用外科手术解决，有些肝内胆小管弥漫性疾病也可出现梗阻性黄疸，称为肝内胆汁淤积性黄疸，如毛细胆管型肝炎（又称胆汁淤积性病毒性肝炎）、原发性胆汁性肝硬化、药物性肝炎和妊娠期特发性黄疸等。此时仅需内科治疗，手术非但无益，反而会加重病情。     

膀胱癌组织P-gp,GST-π和TOPO-Ⅱ表达评估灌注化疗

目的：探讨膀胱癌的多药耐药性(MDR)，指导灌注化疗用药。方法：采用免疫组化法检测44例膀胱癌病理标本中P-糖蛋白(P-gp)、谷胱肽S转移酶(GST-π)和拓扑异构酶(TOPO—Ⅱ)的表达，评估肿瘤耐药谱。结果：①P-gp检测显示，54．5％的病例对阿毒索、丝裂毒索、长春新碱等抗生索类和生物碱类抗癌药高耐药。②GST-π检测显示仅34．1％的病例对顺铂、环磷酰胺等高耐药，而反有56．8％的病例对该类药无耐药或低度耐药。③TOPO-Ⅱ检测显示对阿霉索、柔红毒索、VP16等TOPO-Ⅱ抑制剂类抗癌药，仅13．6％的病例高度耐药，29．5％中度耐药。56．8％低度耐药。结论：检测膀胱癌MDR，了解多药耐药谱，可指导灌注化疗用药。     

外科围手术期糖尿病的治疗

目的:探讨外科手术病人伴发糖尿病的治疗及围手术期处理。方法:对1998年至2000年收治的125例外科手术伴发糖尿病病例进行回顾总结。结果:93例给予补液、降糖等处理无1例死亡。其他32例未进行有效的降糖处理,死亡5例。结论:外科手术病人伴发糖尿病时,围手术期要控制血糖,可以降低手术并发症及死亡率。     

肩锁钩板治疗不稳定性锁骨外侧段骨折的临床研究

目的：比较肩锁钩板和传统克氏针内固定治疗不稳定性锁骨外侧段骨折的疗效。方法：54例不稳定性锁骨外侧段骨折的患者接受了手术治疗，内固定分别是锁骨钩板或克氏针，根据国外的锁骨外侧段骨折肩部功能评价标准进行6－12个月的术后随访，随访结果运用统计学方法进行分析处理，结果：克氏针内固定组的手术优良率为77．3％，并发症发生率为27．3％，骨折愈合率为81．8％；锁骨钩板内固定组的手术优良率为100％，并发症发生率为3．1％，骨折愈合率100％。两组数据统计学差异有显著性，结论：在不稳定性锁骨外侧段骨折的手术治疗中，锁骨钩板较传统克氏针内固定有较高的手术优良率和骨折愈合率，且并发症的发生率较低，因此，它是一种疗效满意的内固定方法。     

重度烧伤患者休克期血浆B型钠尿肽含量变化及意义

Objective To study the plasma content of B-type natriuretic peptide (BNP) in patients with severe burn during shock stage and probe its clinical significance. Methods Forty-two patients aged 18-60 years, with total burn surface area ≥30%TBSA or full-thickness burn area ≥10% TBSA, hospital-ized within 4 hours after burn, were divided into A group (with total burn surface area 30% -50% TBSA or full-thickness burn area 10% -20% TBSA, n = 21 ), and B group (with total burn surface area 50% TB-SA or full-thickness burn area > 20% TBSA, n = 21 ). Twenty patients admitted during the same time for plastic surgery were enrolled as control group. The plasma levels of BNP, creatine kinase (CK), CK-MB, troponin I (Tnl) of all patients were determined on admission. The levels of BNP, Tnl and fluid resuscita-tion volume were examined at 8, 16, 24, 48 post burn hour (PBH) in A and B groups. Analysis of correla-tion between BNP and fluid resuscitation volume was performed. Results On admission: BNP level in A group (68±19 ng/L) and B group (99±38 ng/L) , respectively, was increased as compared with that in control group (17±7 ng/L, P <0.01 ). Tnl level in A group (2.13±0.67 μg/L) and B group (2.98± 0.58μg/L), respectively, was increased as compared with that in control group (0.12 ± 0.03 μg/L, P < 0.01). There was no obvious difference in CK, CK-MB levels among A, B, and control groups ( P > 0.05). BNP levels in A, B groups continuously rose during 8 - 48 PBH, and they were positively correlated with fluid resuscitation volume. TnI level peaked at 24 PBH, and decreased at 48 PBH. Conclusions The plasma level of BNP is sensitive to reflect changes in myocardial ischemia and hypoxia as a rise in level of TnI in shock stage of severe burn, and it was positively correlated with fluid resuscitation volume. BNP can be used to guide fluid resuscitation during shock stage.
