不同剂量普伐他汀治疗急性脑梗死的疗效和安全性研究

目的：探讨不同剂量普伐他汀在脑梗死急性期治疗的可行性、降脂疗效及安全性。方法：脑梗死急性期病人146例，随机分为3组，A组（50例）为对照组，B组（49例）每晚服普伐他汀10mg，C组（47例）每晚服普伐他汀20mg，观察30d。比较治疗前后血脂、神经功能缺损评分、生化指标等变化，并记录服药后不良反应。结果：各组总胆固醇（TC）、低密度脂蛋白（LDL-C）、超敏C-反应蛋白（hs-CRP）在治疗后都有所下降，C组下降最显著，B组次之，A组下降程度较小。A组TG治疗前后无明显变化，B组和C组TG治疗后有所下降，两组间无明显差别。脂蛋白（Lpa）在A组治疗后有下降，B组无明显变化，C组较前轻度升高。各组治疗前后神经功能缺损评分均有降低，但各组之间比较无明显差异（P〉0.05）。观察期间所有病人均能耐受普伐他汀，治疗前后肝、肾功能、肌酸激酶（CK）等无明显变化。结论：在脑梗死急性期应用普伐他汀（每日10～20mg）是安全可行的，且每日20mgTC、TG降低更显著，脑梗死急性期的病人应用普伐他汀后取得较好的降脂疗效，神经功能缺损评分的改善有待较长期观察。     

One-year follow-up of the outcome of a randomized controlled trial of a home-based intervention programme for children with autism and developmental delay and their families

Introduction There is debate about the type and intensity of early childhood intervention that is most helpful for children with developmental problems. The aim of the study was to determine whether a home‐based programme provided over 12 months resulted in sustained improvement in development and behaviour 12 months after the intervention ceased. The characteristics of the children and families who benefited most from the intervention were also studied. Method Randomized controlled trial. Participants A total of 59 children, aged 3–5 years, attending two early childhood intervention centres in Melbourne, Australia. Intervention Half of the subjects received an additional home‐based programme consisting of 40 weekly visits. Main outcome measures Bayley Scales of Infant Development and Wechsler Preschool and Primary Scale of Intelligence Revised, Preschool Behaviour Checklist, Bayley Behaviour Rating Scale and Behaviour Screening Questionnaire. All tests administered pre‐intervention, following the intervention and 12 months later. Secondary outcome measures Family stress, support and empowerment. Results Fifty‐four children completed the assessments 12 months after conclusion of the intervention. Compared with the control group, improvement in aspects of cognitive development in the children who received the extra intervention was sustained 1 year later (P= 0.007) while significant behavioural differences post intervention were not. Analyses of the data by the Reliable Change Index indicated improvement of clinical significance occurred in non‐verbal areas. In contrast to the control group who deteriorated, language skills in the intervention group remained stable. Improvements were significantly associated with higher stress in the families. Conclusion Improvements following the provision of a home‐based programme to preschool children with developmental disabilities were sustained 1 year later. Children from highly stressed families appeared to benefit most, reinforcing the importance of involving families in early childhood intervention programmes.     

脑梗死后早发性癫(癎)发作临床特点分析

目的:探讨脑梗死(CI)后早发性癫癎发作(EES)的临床特点。方法:对2643例确诊为CI患者的临床资料进行回顾性研究。结果:CI后EES的发生率为4.58%,女性高于男性(P<0.05);婴幼儿及未成年人高于成年人(P<0.01)和老年人(P<0.01);累及皮质的发生率高于未累及皮质的(P<0.01);EES作为CI首发症状者占49.59%,24h内出现者占76.03%,1周内出现者占94.21%,仅有5.79%在第2周出现;局灶性发作占65.29%,全面性发作占34.71%;给予AEDs治疗发作均可控制,伴有EES的患者病死率高于不伴有者(P<0.05)。结论:CI后EES较为常见,女性多于男性,未成年人的发生率高于成年人及老年人,与梗死部位有关,以局灶性发作为主,抗癫癎治疗有效,临床预后较差。     

感染性休克早期目标指导性治疗方案的应用体会

目的 为加强外科围手术期处理，观察应用早期目标指导性治疗方案（early goal directed therapy，EGDT）对感染性休克患者的救治效果。方法 运用EGDT使入ICU8h内的感染性休克患者的中心静脉压（CVP）、平均动脉压（MAP）和上腔静脉血氧饱和度（ScvO2）达标。结果 本组20例感染性休克患者，在8h内CVP达标20例，MAP达标20例，ScvO2达标16例。结论 应用EDGT治疗感染性休克有较好的理论基础和实用性，在限定的时间内使所有的目标值达标存在一定的困难。     

肾结核90例临床分析

目的 探讨肾结核的临床特征及有效治疗方法。方法 回顾性分析90例肾结核患者的临床资料。结果 近年来肾结核病例仍较多见，早期诊断困难，单纯药物治疗可治愈者约16％，手术切除仍是主要治疗方法。结论 不典型肾结核的发病率仍较高。尿常规、B超、静脉肾盂造影为主要诊断方法，诊断性治疗仍是确诊的重要依据。     

Cognitive behavioral treatment for young children with obsessive-compulsive disorder.

Obsessive-compulsive disorder (OCD) is a distressing and functionally impairing disorder that can emerge as early as age 4. Cognitive behavior therapy (CBT) for OCD in youth shows great promise for amelioration of symptoms and associated functional impairment. However, the empirical evidence base for the efficacy of CBT in youth has some significant limitations, particularly as related to treating the very young child with OCD. This report includes a quantitative review of existing child CBT studies to evaluate evidence for the efficacy of CBT for OCD. It identifies gaps in the literature that, when addressed, would enhance the understanding of effective treatment in pediatric OCD. Finally, it presents a proposed research agenda for addressing the unique concerns of the young child with OCD.

Regional Variation and Use of Exception Letters for Cadaveric Liver Allocation in Children with Chronic Liver Disease

The Pediatric End-Stage Liver Disease (PELD) score was designed to reduce subjectivity in liver allocation and to advantage patients with a higher probability of waiting list mortality. The aims of this study were to determine the impact of PELD implementation for children with chronic liver disease and to assess whether PELD met its goal of standardization of liver allocation for children. This study used data reported to the United Network for Organ Sharing (UNOS) registry for children with chronic liver disease receiving primary cadaveric liver transplant between January 2000 and December 2001 (pre-PELD) and March 2002 and July 2003 (PELD). PELD reduced the percentage of children transplanted while in an intensive care unit and as status 1. A calculated PELD score was used for allocation in only 52% of recipients. Thirty percent were status 1 at transplant and PELD scores granted by exception were used for allocation in 18% of patients. There was regional variation in PELD score at allocation and use of exception scores with a significant relationship between PELD score and percentage of exception cases. Regional variation suggests that PELD has not resulted in standardization of listing practices in pediatric liver transplantation.     

Autologous implantation of chondrocytes on a solid collagen scaffold: clinical and histological outcomes after two years of follow-up

Abstract From our overall experience in 56 patients, we here report the treatment with matrix-induced autologous chondrocyte implantation (MACI) of 35 patients suffering from knee cartilage defects measuring about 4 cm², and followed for a minimum of 6 months. A total of 36 knees were treated (1 patient on both knees) and clinically observed for 22 months (in some cases for over 39 months), in accordance with a standardised protocol. Subjective parameters (pain, well-being, functional state, symptoms during specific activity) and objective outcomes (IKDC score and Lysholm and Tegner scores) were recorded. One or 2 years after implantation, some biopsies of the regenerated cartilage were histologically evaluated. The subjective parameters (VAS pain score, 2.80±1.49, p<0.0001; change vs. basal score, 2.72) promptly normalized after 1 month, as did the objective ones (IKDC score after 6 months, 1.53±0.59, p<0.0001; change vs. basal score, 1.78). Similar results were observed after the treatment of a femoropatellar kissing lesion. The three cartilage biopsies that were analysed from different patients showed a tissue positivity to immunohistochemical markers of hyaline cartilage. The conclusions of this preliminary analysis are that the clinical outcome and histological evaluation suggest that MACI is able to relieve pain and restore the functionality of the knee, and that the treatment appears capable of regenerating hyaline cartilage.     

小儿病毒性脑膜炎病原诊断与临床分析

应用酶联免疫吸附（ELISA）方法，对88例临床诊断病毒性脑膜炎患儿急性期及恢复期脑脊液进行了单纯疱疹病毒（HSV－I、HSV－Ⅱ）、柯萨奇B组病毒（CoxBV）、埃可病毒（ECHO）、EB病毒（EBV）、腺病毒（AdV)及流感病毒（IFV）特异性IgM抗体检测。结果表明：HSV、CoxBV、ECHO、EBV、AdV、IFV病毒感染率分别为9．09％、18．18％、22．72％、3．41％、4．54％、5．68％；HSV及EBV感染致残率及病死率分别为87．5％（7／8）和100％（3／3）。提示脑脊液中病毒特异性IgM抗体检测可作为早期病原诊断的指标之一；CoxBV及ECH病毒是本地区小儿中枢神经系统病毒感染的主要病毒；HSV及EBV感染致残率及病死率较其它病毒高，预后不良；早期阿昔洛韦治疗，可大大降低病死率。
