Objective To assess the effectiveness and safety of Tongxinluo Capsule in the treatment of vertebrobasilar artery insufficiency. Methods The Cochrane Library, MEDLINE, VIP and CNKI were searched. Two authors independently collected data, including randomized controlled trials that met the inclusion criteria. They evaluated the quality of these trials and performed meta-analysis using The Cochrane Collaboration’s RevMan 5.0. Results Eleven studies involving 1157 participants were included. All the included studies were inadequate at reporting randomization, concealment of allocation and blinding. Meta-analysis based on the included studies showed that Tongxinluo Capsule with Danshen was better than Danshen alone in vertebrobasilar artery insufficiency (RR= 1.35, 95%CI 1.24 to 1.48) and blood flow velocity of vertebrobasilar artery (WMD=3.60, 95%CI 2.44 to 4.77 and WMD=3.46, 95%CI 1.89 to 5.04). Tongxinluo Capsule with simple basic therapy was better than simple basic therapy alone in vertebrobasilar artery insufficiency (RR=1.21, 95%CI 1.11 to 1.31) and blood flow velocity of vertebrobasilar artery (WMD=3.85, 95%CI 2.19 to 5.51). Conclusion Tongxinluo Capsule is an effective and safe drug for vertebrobasilar artery insufficiency. However, due to the limited quantity and quality of the included studies, we can not draw a firm conclusion about the effectiveness of Tongxinluo Capsule compared to the simple basic therapy or Danshen. The results suggest that further and larger-scale trials using Tongxinluo Capsule for vertebrobasilar artery insufficiency are needed.
Objective To assess the effectiveness of exemestane in the treatment of postmenopausal women with breast cancer. Methods We searched The Cochrane Library, PubMed, CBMdisc, and CNKI to identify randomized controlled trials (RCTs) that met the inclusion and exclusion criteria. Two reviewers extracted the data and evaluated the quality of included trials, respectively. Meta-analysis was performed using RevMan 5.0 software. Results A total of 12 RCTs involving 6 166 participants were included, and the results of meta-analyses showed that: (1) When used in neoadjuvant endocrine therapy after operation, exemestane was more effective in progression-free survival than tamoxifen; (2) When used in rescue therapy, exemestane was more effective in objective response than tamoxifen, but not more effective than letrozole or anastrozole; (3) When used in new neoadjuvant endocrine therapy before operation, exemestane was not more effective than letrozole, and there was too little research about it. Conclusions The current evidence shows that exemestane has certain short-term therapeutic effect, but its long-term therapeutic effect is unknown. More high-quality clinical trials are expected for further study.
【摘要】 目的 探討非諾貝特致藥品不良反應（ADRs）的一般規律和特點。 方法 檢索PubMed（1978年-2009年8月）、中國期刊全文數據庫CNKI（1980年-2009年8月）、中國生物醫學文獻數據庫CBMDise（1980年-2009年8月）非諾貝特所致ADRs文獻，進行統計、分析。 結果 非諾貝特致ADRs多發生在gt;40歲年齡段，與性別無顯著關聯；64例ADRs主要涉及骨骼肌肉系統、消化系統、泌尿生殖系統、過敏反應，及時處理者預后良好。 結論 臨床上應重視非諾貝特所致ADRs，及時處理。【Abstract】 Objective To analyse the clinical features, correlation factors, preventions and cures of (adverse drug reactions, ADRs) caused by fenofibrate. Methods The cases of ADRs caused by fenofibrate were collected and analyzed from Pubmed (1978 - August 2009), CNKI (1980 - August 2009) and CBMDise (1980 - August 2009). Results Fenofibrate-induced ADRs were mostly seen in patients over 40 years old, but which was independent for sex. Totally, 64 ADRs were involved in the skeletal musculature system, digestive system, urinogenital system, and allergic response. The prognosis was favorable. Conclusion More attention should be given to patients with fenofibrate and ADRs should be treated as soon as possibile.
Objective To compare lamivudine monotherapy versus lamivudine-thymosin alpha-1 combination therapy for HBeAg positive chronic hepatitis B. Methods We searched CENTRAL (Issue 4, 2008), PubMed (up to December 2008), the Chinese Biomedical database (CBM, up to December 2008), and CNKI (up to December 2008). We also scanned references of all included studies and pertinent reviews. Quality assessment and data extraction were conducted by two reviewers independently. Meta-analyses were conducted using RevMan 5.0. Results We identified 23 trials involving 1 488 patients. According to the results of meta-analyses, the HBeAg seroconversion rate of the combination therapy group was higher than that of the monotherapy group, both at the end of the treatment and the one year follow-up (RR=2.89, 95%CI 2.40 to 3.48; RR=4.99, 95%CI 2.99 to 8.31); and there were also significant differences between the two groups for secondary outcomes including HBV-DNA negative, ALT normalization, etc.. There was no significant difference between the two groups in adverse reaction. Conclusion Lamivudine-thymosin alpha-1 combination therapy might be more effective than lamivudine monotherapy for HBeAg positive chronic hepatitis B. However, the results should be interpreted with caution because of the low quality of the included studies. High-quality, large scale randomized controlled trials are needed to further prove the results.
Objective
To summarize types of post-mastectomy breast reconstruction and present situation.
Method
The relevant literatures about post-mastectomy breast reconstruction in recent years were reviewed.
Results
With the increasing incidence of the breast cancer and the progressing of the treatment methods, it has become a trend for the post-mastectomy breast reconstruction. If the patient’s condition is allowed, the post-mastectomy breast reconstruction can be performed. At present, the post-mastectomy breast reconstruction mainly include the implant based reconstruction, autologous tissue reconstruction, autologous fat transplantation, etc.. There are different options for the breast reconstruction according the indicators and it had the corresponding complications. So the selection of reconstruction technique depend on the individual requirements, determining by the patient choice, advice of the reconstructive surgeon, and anticipated post-mastectomy therapy, particularly the needs for the radiotherapy and chemotherapy, etc..
Conclusions
Post-mastectomy breast reconstruction is common abroad, corresponding research has been carried out in our country, experiences in learning are shairing. With deepening of domestic and foreign exchanges and progressing of technology, it is believed that post-mastectomy breast reconstruction might become one of conventional reconstruction options in future.
Objective
To summarize the progress of biological indexes which could predict the efficiency of neoadjuvant chemotherapy for breast cancer.
Methods
Various related researches were collected to make a review.
Results
Many indexes linked to the efficiency of neoadjuvant chemotherapy for breast cancer according to several studies. According to many studies, indexes such as human epidermal growth factor receptor-2 (HER-2) gene, estrogen receptor (ER), progesterone receptor (PR), Ki-67, P53 gene, neutrophil to lymphocyte ratio (NLR), platelet level, and mean platelet volume (MPV) may have association with the outcome of neoadjuvant chemotherapy in treatment of breast cancer, and these factors maybe individual biomarkers to predict the efficiency of the treatment, but no coincident conclusion has been reached for these indexes.
Conclusion
The value of these indexes that predict the efficiency of neoadjuvant chemotherapy is not sure, further study need to be done to solve this topic.
