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.

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.
ObjectiveTo investigate the early clinical results of MitraClip system in domestic patients. Methods We retrospectively analyzed the clinical data of 36 patients who underwent transcatheter edge-to-edge repair procedure using MitraClip system in Beijing Fuwai Hospital, Shenzhen Fuwai Hospital and Fuwai Yunnan Cardiovascular Hospital between January and June 2021. There were 24 males and 12 females, with a median age of 70 (47-86) years. Ten (27.8%) patients had 3+ mitral regurgitation (MR) and 26 (72.2%) patients had 4+ MR preoperatively. ResultsAll procedures were successfully performed. The reduction in MR was 2+ at least immediately after surgery, and 91.7% of patients had MR≤2+ at 3 days postoperatively. There was no statistical difference in left ventricular ejection fraction change postoperatively. Forward velocity and peak gradient of mitral valve were increased after the procedure. Mean gradient of mitral valve were increased at 3 days postoperatively than immediately after surgery (P<0.001). Two patients had acute pericardial effusion intraoperatively, and received pericardial puncture and drainage immediately. ConclusionMitraClip system has been applied well in domestic patients and can significantly improve MR. This sutdy has a good consistency with foreign studies, and the early results are satisfactory.
ObjectiveTo explore the safety and effectiveness of different interventional approaches for the treatment of patent ductus arteriosus (PDA) in children.MethodsThe children (≤7 years) who underwent interventional treatment for PDA from 2019 to 2020 in our hospital were retrospectively included. The patients were divided into 3 groups according to the procedures: a conventional arteriovenous approach group, a simple venous approach group, and a retrograde femoral artery approach group. The clinical efficacy of the patients was compared. Results A total of 220 patients were included. There were 78 males and 142 females, with an average age of 3.21±1.73 years, weight of 14.99±5.35 kg, and height of 96.19±15.77 cm. The average diameter of the PDA was 3.35±1.34 mm. A total of 85 patients received a conventional arteriovenous approach, 104 patients received a simple venous approach, and 31 patients received a retrograde femoral artery approach. The diameter of PDA in the retrograde femoral artery group was smaller than that in the other two groups (3.44±1.43 mm vs. 1.99±0.55 mm; 3.69±1.17 mm vs. 1.99±0.55 mm, P<0.001); the contrast medium usage [40 (30, 50) mL vs. 20 (20, 30) mL; 35 (25, 50) mL vs. 20 (20, 30) mL, P≤0.001] and operation time [32 (26, 44) min vs. 25 (23, 30) min; 29 (25, 38) min vs. 25 (23, 30) min, P<0.05] in the simple venous approach group were significantly less or shorter than those in the other two groups; the length of hospital stay of the conventional arteriovenous group was longer than that in the other two groups [3 (3, 5) d vs. 4 (3, 6) d; 4 (3, 5) d vs. 4 (3, 6) d, P<0.05]. There was no significant difference in postoperative complications.ConclusionIt is safe and effective to close PDA through simple venous approach. The retrograde femoral artery approach has the advantage of simplifying the surgical procedure for PDA with small diameters.
