The role of cardiopulmonary exercise testing in evaluating children with exercise induced dyspnoea

Exercise induced dyspnoea (EID) is a common manifestation in children and adolescents. Although EID is commonly attributed to exercise induced bronchoconstriction, several conditions other than asthma can cause EID in otherwise healthy children and adolescents. Cardiopulmonary exercise testing (CPET) offers a non-invasive comprehensive assessment of the cardiovascular, ventilatory and metabolic responses to exercise and is a powerful diagnostic and prognostic tool. CPET is a reproducible, non-invasive form of testing that allows for comparison against age- and gender-specific norms. CPET can assess the child’s exercise capacity, determine the limiting factors associated with this, and be used to prescribe individualised interventions. EID can occur due to asthma, exercise induced laryngeal obstruction, breathing pattern disorders, chest wall restriction and cardiovascular pathology among other causes. Differentiating between these varied causes is important if effective therapy is to be initiated and quality of life improved in subjects with EID.     

Prospective comparative study of intraoperative “Towel clip test” and “Vertical patella test” assessing lateral retinaculum tightness in patients undergoing TKA

BackgroundProper patellar tracking is one of the most important aspect of TKA to ensure good functional outcome. A patellar tracking problem noted intraoperatively serves as a warning sign and should prompt the surgeon to reassess position of each component. Various tests are there to assess lateral retinaculum tightness viz. "No thumb test", "Towel clip test". A new test "Vertical patella test" is described to assess lateral retinaculum tightness. A study was conducted to assess the effectiveness, correlation and validity of two techniques.Materials & MethodsPatients >50 years of age and with diagnosis of Osteoarthritis knee having less than 30 varus and flexion deformity going in for primary TKA were selected with a sample size of 100 knees in a tertiary care centre. Revision cases or patients with flexion contracture more than 30, complex knee surgery; with pre existing patellar tilt were excluded from study.ResultsResults of both tests were found to correlate in 75% of case with sensitivity of 96.65% and specificity of 75.00%. Kappa came out to be 0.634 which shows good agreement of vertical patella test and towel clip test. Result was computed using excel and SPSS and was found to be significant with p value< 0.05. Lateral retinaculum release was done in 8 knees.ConclusionsVertical patella test correlates with towel clip test, is easy to perform and saves time. The limitation of our study was small sample size.     

自拟温润方治疗风寒袭肺型急性咳嗽病的临床观察

目的 观察自拟温润方治疗风寒袭肺型急性咳嗽病的临床疗效。方法 64例风寒袭肺型急性咳嗽病患者,随机分为对照组(31例)和治疗组(33例)。对照组患者给予复方甘草口服溶液治疗,治疗组患者给予温润方治疗。比较两组患者治疗前和治疗3、6 d后的中医症状评分以及临床疗效。结果 治疗3、6 d后,两组患者咳嗽、咯痰、恶风、咽痒、鼻塞、流涕、鼻干、口干咽燥症状评分均低于治疗前,差异均具有统计学意义(P<0.05)。治疗组患者治疗3 d后咳嗽、咽痒、鼻干、口干咽燥症状评分分别为(2.18±0.98)、(1.15±0.81)、(0.60±0.61)、(0.81±0.71)分,均低于对照组的(3.04±1.62)、(1.68±0.96)、(0.96±0.67)、(1.37±0.86)分,差异均具有统计学意义(P<0.05);治疗组患者治疗6 d后咳嗽、咽痒、鼻干、口干咽燥症状评分分别为(0.54±0.51)、(0.42±0.48)、(0.40±0.46)、(0.47±0.51)分,均低于对照组的(1.12±0.76)、(1.11±0.98)、(0.88±0.98)、(1.01±0.92)分,差异均具有统计学意义(P<0.05)。两组患者治疗3、6 d后咯痰、恶风、鼻塞、流涕症状评分比较,差异无统计学意义(P>0.05)。治疗3 d后,治疗组治疗总有效率90.9%高于对照组的71.0%,差异具有统计学意义(P<0.05)。治疗6 d后,治疗组患者治疗总有效率93.9%与对照组的90.3%比较,差异无统计学意义(P>0.05)。结论 在风寒袭肺型急性咳嗽病治疗中,温润方在缓解咳嗽以及部分次症方面明显优于复方甘草口服溶液,起效更快。     

Emodin attenuates acute lung injury in Cecal-ligation and puncture rats

Acute lung injury (ALI) is a major cause of sepsis-induced acute respiratory failure. Emodin has been considered to play a protective role for acute lung edema in cecal ligation and puncture (CLP)-induced sepsis model. In this study we aimed to investigate whether emodin could improve CLP-induced lung sepsis via regulating aquaporin (AQP) and tight junction (TJ), inflammatory factors, and pulmonary apoptosis. The results showed that sepsis-induced pulmonary pathological changes were significantly improved after emodin treatment. Emodin was found to upregulate AQP and TJ expression in the CLP model. Meanwhile, inflammatory cytokine release and pulmonary apoptosis was remarkably reduced after emodin treatment in lung sepsis. Our data demonstrated that emodin could suppresse inflammation, restore pulmonary epithelial barrier and reduce mortality in CLP-induced ALI, suggesting the potential therapeutic application of emodin in sepsis.     

急诊心肌梗死冠状动脉介入治疗术后患者T3水平与心肌再灌注的关系

目的探讨急性心肌梗死（AMI）患者急诊经皮冠状动脉介入治疗（PCI）术后血清三碘甲状腺原氨酸（T3）与心肌再灌注的关系。方法采用化学发光法检测205例AMI患者PCI术后血清T3水平，根据T3水平将患者分为A、B、C、D4组，记录并比较4组患者术后冠状动脉TIMI血流分级、心肌呈色分级（MBG）。结果A组（重度低T3组）TIMI3级比例低于B、C、D组，差异有统计学意义（P＜0.01）；MBG3级比例低于B、C、D组，差异有统计学意义（P＜0.01）。女性患者T3水平（1.00±0.05）nmol/L、TIMI3级比例（32/46，69.6%）、MBG3级比例（24/46，52.2%）均低于男性患者，后者分别为（1.19±0.02）nmol/L、（143/159，89.9%）、（110/159，69.2%），差异均有统计学意义（P＜0.05或0.01）。结论女性AMI患者心肌再灌注水平较男性患者低。AMI患者T3水平与PCI术后冠状动脉再灌注相关，监测T3可以间接反映病情的严重程度。
