【摘要】 目的 总结慢性阻塞性肺疾病（chronic obstructive pulmonary disease，COPD） 患者院外用药情况，并分析其院外用药情况、痰真菌检出率以及激素不良反应发生率的变化。 方法 调查2011年1-6月住院的161 例COPD 患者院外用药情况，将其分为遵医嘱使用糖皮质激素组（A组，包括口服和吸入激素）、使用非准字号药物组（B组）和未使用以上两种药物组（C组），对各组的痰真菌检出率进行统计学分析，并对A、B组激素不良反应的发生率进行分析。再将现阶段的调查结果与2006年同样研究结果进行比较。 结果 161例患者中使用口服糖皮质激素6例，使用吸入激素29例，使用非准字号药物32例，未使用以上两种药物94例。痰真菌检出率情况:B组检出率为62.5%，明显高于A组的17.14%、C组的27.66%；组间比较有统计学意义（Plt;0.001）。B组的药物不良反应发生率为37.5%；A组中口服激素发生率为50%，而使用吸入激素发生率为0%。与2006年同样研究结果比较，B组患者的比例明显下降，A组患者明显增多。 结论 使用非准字号药物的患者，真菌感染的危险性及激素不良反应的发生率较高，健康教育对于减少这些不良现象的发生发挥了重要作用。【Abstract】 Objective To investigate the use of drugs in patients with chronic obstructive pulmonary disease (COPD) outside the hospital, and analyze the detection rate of fungus and the side effects of glucocorticosteroids (GCs), and their changes. Methods We investigated the drugs used outside the hospital in 161 patients with stable COPD between January and June 2011, who were divided into prescribed medication GCs group (group A, including oral GCs group and inhaled GCs group), drugs without authorization by SFDA (DWAS) group (group B) and other drugs group (group C). Then we made a statistical analysis on the detection rate of fungus, and the incidence rate of the side effects of GCs in the three groups. Finally we compared the present findings with the similar studies five years ago. Results Among the 161 patients, 6 took oral GCs, 29 used inhaled GCs, 32 used DWAS, and 94 used other drugs. The detection rate of fungus in group B was 62.5%, obviously higher than the other groups (17.14% in group A, and 27.66% in group B, Plt;0.05). The rate of side effects of GCs in group B was 37.5%, and 50% in oral GCs group, while no side effects of GCs was found in the inhaled GCs group. Compared with the similar study five years ago, the use of DWAS decreased, and the use of prescribed medication GCs among the patients increased significantly. Conclusions Patients taking DWAS have a high incidence rate of mycotic infection and side effects of GCs. Health education plays an important role in reducing the occurrences of these undesirable phenomena.
Objective To explore the perioperative management of the coexisting diseases for the elderly patients with gastric cancer. Methods The clinical data of perioperative management for coexisting diseases in 528 patients with gastric cancer over 70 years old treated in the First Affiliated Hospital of China Medical University from March 1980 to November 2008 were analyzed retrospectively. Results The main coexisting diseases included cardiovascuclar disease (259 cases, 49.05%), respiratory disease (161 cases, 30.49%), diabetes (72 cases, 13.64%). Adjusting blood pressure and blood glucose, improving cardiopulmonary function, and hepatic and renal function were mainly given. The common postoperative complications included intestinal obstruction (10 cases), pneumonia (10 cases), reflux esophagitis (9 cases), functional evacuation disorder of gastric remnant (7 cases), and anastomotic leakage (5 cases). Ten patients died during perioperative period: 6 died of heart and lung failure, 2 of acute myocardial infarction, 1 of anastomotic leakage, 1 of intestinal obstruction. Conclusions The common coexisting diseases in the elderly patients with gastric cancer are hypertension， bronchitis and diabetes. Complete assessment of the patient’s general health before operation and intensive perioperative management of the coexisting diseases not only can decrease the risk of surgical procedures， but also decrease the incidence of complication and perioperative mortality.

Objective To investigate the current situation of randomized controlled trials (RCTs) on compound salvia pellet (CSP) for angina pectoris and assess whether there is adequate evidence for clinical practice. Methods We collected all the published clinical studies on CSP for angina pectoris from 1994 to December 2005, and assessed each included report using the Jadad scale, the revised CONSORT statement and other self-edited items. Results We finally identified 115 RCTs. Among which, 1 scored 3 points, 6 scored 2 points, 106 scored 1 points and 2 socred 0 points. No RCT performed allocation concealment according to the CONSORT criteria, only 4 RCTs (3.5%) described the generation of the randomization sequence, among which 2 were quasi-randomized. No RCT provided randomization implementation,1 RCT (0.9%) carried out placebo control, 1 RCT (0.9%) reported endpoint, 9 RCTs (7.8%) adopted single blinding, 4 RCTs (3.5%) reported double blinding, 11 RCTs (9.6%) calculated statistical values, 2 RCTs (1.7%) provided the record of follow-up, 1 RCT (0.9%) reported negative outcome, 25 RCTs (21.8%) described adverse events, no RCT described how the sample size was estimated, and how an intent-to-treat (ITT) analysis and correlation analysis were reported, 1 RCT (0.9%) was multi-center, no RCT completed ethical approval and informed consent, 27 RCTs (23.5%) described syndrome type of TCM. Conclusion Currently, the methodology and reporting of studies on CSP for angina pectoris are not good enough to provide reliable evidence for clinical practice.
Objective To analyze the influencing factors on postoperative complications and mortality of gastric cancer after total gastrectomy. Methods The clinical data of 622 patients with gastric cancer received total gastrectomy were collected. According to the extent of lymph node dissection, the patients were divided into 2 groups: D0/D1 group (n=35) and D2/D3 group (n=587). The risk factors influencing postoperative morbidity and mortality were determined by logistic multiple regression analysis. Results The total postoperative complication morbidity and mortality for all patients were 9.81% (61/622) and 2.89% (18/622), respectively. The postoperative complication morbidity was 8.57% (3/35) and 9.88% (58/587) in the two groups, the postoperative mortality was 2.86% (1/35) and 2.90% (17/587) in the two groups, there were no significant differences between the two groups (Pgt;0.05). The most common postoperative complication was intestinal obstruction (18.03%, 11/61). Multivariate analysis revealed that risk factors on the postoperative complications and mortality were age ≥ 70 years, TNM stage Ⅳ, preoperative complication, palliative excision, merely manual or mechanical anastomosis, and multivisceral resection (Plt;0.05), however, the extent of lymph node was not influencing factor (Pgt;0.05). Conclusions Patients with advanced gastric cancer have a high risk of postoperative complications and mortality. Multiple organ resection should be avoided for patients with gastric cancer of TNM stage Ⅳ.
Objective To compare the efficacy and indication of the three different surgical methods in the treatment of the senile osteoporotic comminuted proximal humerus fracture. Methods From January 2006 to April 2008, 70 senile patients with osteoporotic comminuted proximal humerus fracture were randomly divided into three groups to receive different surgical methods. There were 21 patients in the group A receiving Kirschner tension band or screw internal fixation, 37 patients in group B receiving internal fixation of locking proximal humeral plate, and 12 patients in group C receiving humeral head replacement. There were 36 males and 34 females aged 53-76 years old (average 61.9 years old). All the fractureswere closed, osteoporotic, and III and IV-part according to Neer classification. The disease course was 1-8 days (average 2.8 days). There was no significant difference among three groups in terms of basel ine information (P gt; 0.05). The effective antiosteoporosis therapy was given during perioperative period. Results All the incision healed by first intention. All patients reached anatomical or almost anatomical reduction without compl ications such as postoperative infection, neurovascular injury, and nonunion of bone. Seventy patients were followed up for 9-20 months (average 11.5 months). The heal ing time of the fracture was 8-12 weeks in group A and group B, the average heal ing time was 10.5 weeks in group A and 10 weeks in group B, and there was no significant difference between two groups (P gt; 0.05). Group C presented with no sign of prosthesis loosening or shoulder dislocation. Six cases in group A suffered from frozen shoulder, pain or acromion impingement syndrome 6 months after operation and obtained various degrees of improvement via functional exercises. One of them had humeral head avascular necrosis 12 months later and achieved fair recovery after performing humeral head replacement. Two cases in group B had frozen and painful shoulder 6 months after operation and achieved fair recovery after functional exercises. One cases in group C had frozen shoulder and poor performance of abduction and upl ifting and achieved improvement after exercises. The rest patients achieved satisfactory curative effects. The incidence of compl ication was 28.6% in group A, 5.4% in group B, and 8.3% in group C. The incidence of complication in group A was significantly higher than that of group B and group C (P lt; 0.05), and there was no significant difference between group B and group C (P gt; 0.05). Neer scale system was adopted to evaluate the postoperative shoulder function, the excellent and good rate was 66.7% in group A, 78.4% in group B, and 83.3% in group C. The excellent and good rate in group A was significantly less than that of group B and group C (P lt; 0.05), and there was no significant difference between group B and group C (P gt; 0.05). Conclusion The senile osteoporotic comminuted proximal humerus fracture treated by surgery can obtain satisfied results. Most patients can use locking plate fixation. Those with poor general condition can use Kirschner wire fixation with tension band or screws, but this method is subject to certain constraints. For some elder patients with humeral head necrosis and humeral head crushed, priority should be given to the use of humeral head replacement.
Objective To systematically review the clinical effectiveness and safety of Lianhuaqingwen capsule in the treatment of influenza. Methods Databases including MEDLINE, The Cochrane Library, PubMed, VIP, WanFang Data, CNKI and CBM were searched to collect the randomized controlled trials (RCTs) on Lianhuaqingwen capsule treating influenza published from 2000 to 2011. The studies were screened according to the inclusion and exclusion criteria, the data were extracted, the quality of the included RCTs was assessed, and meta-analysis was performed using RevMan 5.0 software. Results Among 12 RCTs included, 11 were in Chinese and 1 was in English. The results of meta-analyses based on stratified therapeutic strategies showed that: a) Lianhuaqingwen caspule vs. other traditional Chinese medicinals (TCM): A total of 5 RCTs were included. Compared with the Lingyangganmao capsule, significant differences were found in the clinically marked effective rate (RR=1.32, 95%CI 1.15 to 1.52), the marked effective rate of temperature (RR=1.31, 95%CI 1.10 to 1.55), and the time of defervescence (RR=3.98, 95%CI –4.81 to –3.15); compared with the Kugan granules, significant differences were found in the clinically marked effective rate (RR=1.33, 95%CI 1.08 to 1.64) and the marked effective rate of temperature (RR=1.58, 95%CI 1.20 to 2.09); compared with the TCM decoction, the time of defervescence was significantly different (WMD=5.52, 95%CI 0.32 to 10.72); and b) Lianhuaqingwen capsule vs. western drugs: A total of 9 RCTs were included. Compared with ribavirin, the clinically marked effective rate was significantly different (RR=1.52, 95%CI 1.15 to 2.02); compared with Phosphate oseltamivir, the clinically marked effective rate was not significantly different (RR=0.96, 95%CI 0.77 to 1.18), and the WMDs (95%CI) of such indexes as the time of defervescence, the duration of cough, sore throat, myalgia, expectoration and headache, and the time of viral shedding were –4.50 (–8.83, –0.17), –10.38 (–13.89, –6.87), –13.92 (–19.81, –8.04), –16.44 (–26.50, –6.39), –10.80 (–18.98, –2.63), –9.24 (–17.92, –0.57), and 1.39 (–7.24, 10.02), respectively. Except for the time of viral shedding, all the other indexes showed significant differences between the two groups. No obvious adverse reactions related to Lianhuaqingwen capsule were reported. Conclusion Current evidence shows that Lianhuaqingwen capsule is more effective than other Chinese medicinals and western drugs in alleviating flu-like symptoms when treating influenza. Due to the low methodological quality of the included RCTs, more high-quality large-scale RCTs need to be conducted to verify this conclusion.
Objective To systematically assess the effectiveness of traditional Chinese medicines (TCM) in treating upper airway cough syndrome (UACS) or postnasal drip syndrome (PNDS). Methods Such databases as MEDLINE (1950 to 2011), PubMed (1996 to 2011), VIP (1989 to 2011), WanFang Data (1998 to 2011), CNKI (1979 to 2011) and CBM (1978 to 2011) were searched for collecting the randomized controlled trials (RCT) or quasi-RCTs about TCM treating UACS/PNDS. The trials were screened according to the inclusive and exclusive criteria, and then after the quality assessment and data extraction were conducted, the statistical analysis was conducted by using RevMan 5.0 software. Results A total of 10 RCTs and quasi-RCTs in Chinese were identified. The results of analysis showed that: a) The integrated Chinese and western medicine was superior to western medicine alone, either for adults and children with UACS, or for adults with PNDS. However the effectiveness had to be further assessed due to lack of high-quality literatures; b) TCM alone was probably more effective than western medicine alone for adults with PNDS, but not for adults and children with UACS. No obvious adverse reaction related to TCM was reported. Conclusion The recent research outcomes show that the integrated Chinese and western medicine is superior to western medicine alone, either for adults and children with UACS, or for adults with PNDS, but no definite evidence is found to support the superiority of TCM in treating UACS/PNDS. More high-quality RCTs with large scale need to be conducted in future to verify this conclusion due to the overall low methodological quality and significantly different intervention of the included trials.
目的 评估中医药临床研究是否与我国主要疾病负担相关。 方法 首先从1999年－2004年出版的13种中医、中西医结合杂志中手工检索出随机对照试验（RCT），并提取出杂志名称、出版年限、治疗的疾病类别及样本含量等数据。然后采用死亡率和伤残调整寿命年（DALY）作为衡量标准，统计2002年我国疾病负担前30位病因的RCT数量，采用秩相关分析这些疾病负担与发表的中医药RCT及其受试者数量的关系。 结果 最终确认7 422个RCT，约38%的RCT来自于3种国家级杂志。这些RCT覆盖了我国疾病负担中的主要病种，其中4 280个RCT（57.7%）研究前30位病因合并产生的42个病种，只有3个病种（7%）没有任何RCT研究。采用DALY得到的相关系数分别是0.108（P=0.569）、0.092（P=0.628），通过死亡率产生的相关系数分别是0.453（P=0.012）、0.536（P=0.002）。 结论 中医药RCT与采用死亡率衡量的疾病负担明显相关，但采用DALY分析却未发现二者存在相关性。中医药临床研究可能更注重死亡率高的病种，一定程度上忽略了DALY衡量的疾病负担。
