目的 探討乙型肝炎病毒（HBV）表面抗原（HBsAg）陽性肝硬化患者血清中HBV前S1抗原(前S1抗原)、HBV e抗原（HBeAg）及HBV核酸定量檢測（HBV DNA）相關性。 方法 2008年7月－2011年5月對97例HBsAg陽性肝硬化住院患者和50份HBsAg陰性的健康體檢者血清進行前S1抗原、HBV血清標志物檢測及實時熒光定量PCR檢測HBV DNA結果進行分析。 結果 97份HBsAg陽性肝硬化患者血清中，前S1抗原、HBeAg及HBV DNA陽性率分別為53.6%（52/97）、22.7%（22/97）及61.8%（60/97）。22例HBeAg陽性血清中，前S1抗原陽性18例（81.8%）， HBV DNA陽性20例（90.9%)。75例HBeAg陰性血清中，前S1抗原陽性34例（45.3%），HBV DNA陽性40例（53.3%），兩者的前S1抗原與HBV DNA結果間都具有很好的相關性。HBV DNA含量與前S1抗原及HBeAg陽性結果顯示：HBsAg陽性的肝硬化患者血清中HBV DNA陰性率為38.1%（含量＜103 copies/mL），而陽性檢出率HBV DNA含量主要集中在103～105 copies/mL，占81.7%（49/60），HBV DNA含量＞105 copies/mL占18.3%（11/60）。 結論 HBsAg陽性的肝硬化患者血清中主要以HBV非HBeAg陽性血清學模式為主，HBV DNA陽性檢出率的含量主要集中在103～105 copies/mL。前S1抗原在HBeAg陽性血清中與其含有HBsAg病毒及HBeAg陽性患者具有很好的相關性，而在HBeAg陰性血清中存在著差異。Objective To study the correlation among Pre-S1 antigen, HBeAg and HBV DNA results in patients with HBsAg-positive liver cirrhosis. Methods We retrospectively analyzed the serum pre-S1-antigen, HBV serum markers and real-time quantitative PCR HBV DNA results in 97 patients with HBsAg-positive liver cirrhosis and 50 HBsAg-negative healthy volunteers in our hospital from July 2008 to May 2011. Results Among the 97 samples of HBsAg-positive liver cirrhosis patients’ serum, the positive rates of Pre-S1 antigen, HBeAg and HBV DNA were 53.6% (52/97), 22.7% (22/97) and 61.8% (60/97), respectively. In the 22 samples of HBeAg-positive serum, the number of positive pre-S1 antigen and HBV DNA was 18 (81.8%) and 20, respectively. In the 75 samples of negative HBeAg serum, the number of positive pre-S1 antigen and HBV DNA was 34 (45.3%) and 40 (53.3%) respectively. The pre-S1 antigen was correlated well with HBV DNA results in both the two groups. HBV DNA level, pre-S1 antigen and HBeAg-positive results showed that the serum HBV DNA negative rate of HBsAg-positive patients with cirrhosis was 38.1% (＜103 copies/mL), while the positive rate of HBV DNA level was mainly concentrated at 103~105 copies/mL, accounting for 81.7% (49/60), and HBV DNA level over 105 copies/mLaccounted for only 18.3% (11/60). Conclusions HBsAg-positive patients with cirrhosis mainly have a serum non-HBeAg-positive HBV serology pattern, and HBV DNA positive rate of the content is mainly concentrated at 103~105 copies/mL. There is a good correlation between pre-S1 antigen in HBeAg-positive serum and patients with HBsAg virus or positive HBeAg, while for Pre-S1 antigen in HBeAg-negative serum, it is quite different.
目的 了解高校護理本科生（下稱護生）在臨床實習階段對帶教教師的具體期望，為臨床帶教老師的培養提供依據。 方法 以杜威的反思思維理論為基礎，使用Van Manen的詮釋現象學研究方法暨反思日記分析，于2011年1月對67名護生的臨床反思日記進行分析；同時采用自行設計的問卷就護生對臨床教學的評價進行調查。 結果 護生對臨床帶教教師的反思主要集中于5個主題，即期望帶教老師制定合理的、有針對性的帶教計劃并采用靈活多樣的教學手段，期望得到帶教老師的肯定和鼓勵，期望得到獨立實踐護理角色的機會，期望帶教老師注重培養護生的臨床思維能力，期望帶教老師擁有良好的綜合素質；護生對臨床教學評價總平均分為（4.51 ± 0.06）分，得分率為87.3%。 結論 臨床帶教老師在不斷提升自身綜合素質的同時，應根據護理本科人才能力培養目標制定合理的實習計劃，選擇恰當的教學方式，提供良好的臨床學習環境，以進一步提高臨床教學質量。
Objective To investigate the prevalence of depression in patients with chronic obstructive pulmonary disease ( COPD) and risk factors. Methods 215 patients with stable COPD were recruited in the study. The Patient Health Questionnaire-9 ( PHQ-9) standardized scale were performed for the depression survey. Meanwhile CAT, pulmonary function test and the history taking ( sex, age, height, weigh, smoking status, education level) were applied to evaluate all the COPD patients. The COPD patients were classified into A, B, C, and D groups according to 2011 GOLD new COPD classification system. Pearson chi-square test and multivariate logistic modeling were used to estimate the prevalence of depression and the risk factors. Results The prevalence of depression in COPD patients whose PHQ-9 scores ≥7 was 37.7% with 18.5% , 35.8% , 46.5% , and 62.5% respectively in A, B, C, and D groups. There was significant difference in prevalence between each groups ( Plt;0.05) . Compared with the COPD patients without depression, the COPD patients with depression had younger age, more female, higher education level, higher CAT scores and smaller means of body mass index ( BMI) . Logistic analysis revealed that depression in COPD was associated with age, sex, education level, BMI, FEV1% pred and CAT scores. The patients who with younger age, female sex, higher education level, lower FEV1% pred, lower BMI and higher CAT scores were had higher rsik to be complicated with depression. However no significant difference was observed between different FEV1 /FVC or smoking status. Conclusions This study confirms the high prevalence of depression in patients with stable COPD, and the prevalence in A, B, C, and D groups of COPD are different. Sex, age, education level, FEV1% pred, BMI, and CAT scores are the risk factors of depression in COPD.
Objective To explore the effect of antihypertensive therapy for hypertension patients from plateau area. Method A retrospective analysis of medical records for Tibetan patients with hypertension from October to December 2013 in Hospital of Chengdu Office of People’s Government of Tibetan Autonomous Region. Results The study recruited 165 patients. The rate of treatment, control, and compliance of hypertension patients were 86.7% (143/165), 23.8% (34/143), 43.4% (62/143), respectively. The main characteristics of hypertension treatment were higher proportions of single-drug therapy (81.1%, 116/143); among those the Tibetan drug (24.1%), calcium channel blockers (21.6%), diuretics (19.0%), and traditional compound preparation (18.1%) were most commonly used in the antihypertensive therapy. Conclusions The rate of treatment was high, but the rate of control and compliance were low in Tibetan patients with hypertension. It was necessary to carry out hypertension education to patients and strengthen the training of doctors at the plateau.
