  • Diclofenac for Preventing Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis: A Systematic Review

    Objective?To assess the effectiveness and safety of diclofenac, one of the routine-used NSAIDs, in preventing post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP). Methods Firstly, the electronic searches were conducted to retrieve Randomized controlled trials (RCTs) from The Cochrane Library, PubMed, Embase, OVID, CBM, CNKI, VIP and WanFang Data. Secondly, 12 kinds of specific Chinese journals like Chinese Journal of Gastroenterology and conference proceedings were hand-searched till June 2011, and all references in all included trials were searched, too. The RCTs on diclofenac for preventing PEP were identified and retrieved. The systematic review was conducted by using methods and principles recommended by the Cochrane Collaboration. Results A total of 5 RCTs involving 675 PEP patients were included. The Meta-analysis showed that diclofenac might reduce the incidence of PEP (OR=0.41, 95%CI 0.18 to 0.95, P=0.04), but the sensitivity analysis indicated this result was not stable. No evidence showed diclofenac could reduce the incidence of severe PEP (OR=0.40, 95%CI 0.08 to 2.06, P=0.27). And no adverse reactions related to the drug were reported. Conclusion Diclofenac may be safe and effective in reducing the incidence of PEP, but it has no significant effect on preventing severe PEP. Considering the methodological and scale limitation of included studies, this conclusion still needs to be proved by more large-scale and high-quality RCTs.

  • Analysis of Risk Factors for Recurrence of Hepatocellular Carcinoma after Liver Transplantation

    ObjectiveTo determine the risk factors for recurrence of hepatocellular carcinoma (HCC) after orthotopic liver transplantation (OLT). MethodsThe clinical data from seventysix consecutive HCC patients who underwent OLT were retrospectively analyzed. The patients were divided into nonrecurrence group (n=53) and recurrence group (n=23) based on recurrence, and the characteristics of tumor recurrence were analyzed. ResultsThe overall recurrence rate of tumor was 30.3% (23/76). By univariate analysis, gender (P=0.449), age (P=0.091), received preoperative therapy or not (P=0.958), tumor numbers (P=0.212), and HBV/HCV infection (P=0.220) were not closely related with tumor recurrence, while the integrality of tumor capsule (P=0.009), tumor stage (P=0.002), tumor diameter (Plt;0.001), vascular invasion (Plt;0.001), and AFP level before transplantation (P=0.044) were significantly related with tumor recurrence. Furthermore, the oneyear recurrence rate of tumor was higher in patients whose AFP level returned to normal within two months after transplantation (Plt;0.001) and tumor diameter was less than 5.0 cm (P=0.001). Multivariate analysis revealed that tumor diameter (P=0.001, OR=6.456, 95%CI: 2.356-17.680), vascular invasion (P=0.030, OR=10.653, 95%CI: 1.248-90.910), and AFP level before transplantation (P=0.017, OR=2.601, 95%CI: 2.196-5.658) were independent risk factors for tumor recurrence. ConclusionMore attentions shall be paid to these patients with tumor diameter gt;5.0 cm, vascular invasion, and AFP level before transplantation ≥400 μg/L, in particular AFP level is beyond normal within two months after transplantation, and antitumor therapy shall be given as soon as possible.

  • Comparative Effectiveness of Medicated γ-IUD (Intrauterine Device) with Other IUDs for Contraception:A Systematic Review

    Objective To evaluate the effectiveness of Medicated γ-IUD compared with other IUDs for contraception. Methods CBMdisc (1986 -2005), VIP (1989 -2005) , CNKI (1994-2005) , The Cochrane Library (Issue 4, 2005 ) and 10 related journals were searched for randomized controlled trials (R.CTs) and quasi-randomized controlled trials (quasi-RCTs) on the comparison between γ-IUD and other IUDs. The quality of included trials was critically appraised. RevMan 4.2.8 software was used for statistical analysis. Results Ten published studies with 8 381 participants were included. The results of meta-analysis were expressed with Peto OR ( cumulative pregnancy rate, cumulative expulsion rate, cumulative rate of removing for medical reasons) or OIL ( cumulative continuation rate ) and 95% CI. Compared with MSSR-165, Medicated γ-25,200 resulted in lower pregnancy rate at 1, 2, 3 years of follow-up [ with the OR (95% CI) 0. 31 (0.15,0.64) , 0. 31 (0. 17,0.54) , 0. 31 (0.19,0. 51) , respectively], lower cumulative expulsion rate in5 year follow-up [0.26 (0.17,0.40), 0.28 (0.20,0.41), 0.30 (0.21,0.42), 0.29 (0.19,0.44), 0.32 (0.21, 0. 48 ), respectively], lower cumulative rate of removing for medical reasons.after 4 year follow-up [0.57 (0.36,0. 92 ) ], and higher rate of cunmlative continuation in 5 years of follow-up 13.35 ( 2.29,4.89 ) , 2.76 ( 2.06,3, 69 ) , 2.41 (1.89,3.08), 2.22 (1.69,2.91), 1.99 (1.55,2.55), respectively]. Compared with TCu220, Medicated γ-25,200 resulted in lower cumulative pregnancy rate after follow-up 2, 3 years [ 0.46 (0.25 ,0.87 ) ; 0.48 (0.27,0. 85 ) ], lower cumulative expulsion rate after 1 year follow-up [ 0. 58 (0.35,0.97) ] , lower cumulative rate of being removed for medical reasons in5 year follow-up [0.37 (0.23,0.59), 0.38 (0.26,0.56), 0.45 (0.32,0.64), 0.47 (0.30,0.73), 0.58 (0.39,0.87), respectively ] and higher rate of cumulative continuation in 5 years of follow-up [ 2. 15 ( 1.61,2.87 ), 2.02 ( 1.56,2.63), 1.72 ( 1.34,2.20), 1.44 ( 1.08,1.91 ), 1, 39 ( 1.07,1.80), respectively]. Compared with Uterus-Cu, Medicated γ-25,200 resulted in higher rate of cumulative continuation after follow-up 1 year [ 0.51 (0.34, 0.77) ]. Compared with MLCu375, Medicated γ-25,200 resulted in lower cumulative rate of being removed for medical reasons and higher rate of cumulative continuation after follow-up for 3 years [ 0. 22 (0.09,0.52) , 2.84 ( 1.64,4. 94 )]. Compared with TCu380A, Medicated γ-25, 200 resulted in lower cumulative rate of being removed for medical reasons and higher rate of cumulative continuation in follow-up for 2 years [ 0.36 ( 0.18,0.73 ), 0.29 ( 0. 12,0.70 ) ; 3.06 ( 1.72,5.44), 3.61 (1.75,7.47) ]. Conclusions Available evidence shows that Medicated γ-IUD has better or equal effectiveness when compared with other IUDs. However, more RCTs with high quality and longer follow up period are needed to confirm the conclusion.

  • Clinical pathological characteristics and prognosis of 468 thymoma patients

    ObjectiveTo assess the correlation of WHO pathological classification and Masaoka stage of thymomas with its prognosis.MethodsA total of 468 patients with thymomas who received surgeries during 2009-2019 in Huashan Hospital, Fudan University, were collected. There were 234 males and 234 females with an average age of 21-83 (49.6±18.7) years. A total of 132 patients underwent video-assisted thoracic surgery (VATS) and 336 patients underwent thymectomy with median sternal incision. The follow-up time was 5.7±2.8 years. The clinical data of the patients were analyzed.ResultsThe amount of intraoperative bleeding was 178.3±133.5 mL in the median sternal incision group, and 164.8±184.1 mL in the VATS group (P=0.537). The operative time was 3.3±0.7 h in the median sternal incision group and 3.4±1.2 h in the VATS group (P=0.376). Postoperative active bleeding, phrenic nerve injury and chylothorax complications occurred in 8 patients, 9 patients and 1 patient in the VATS group, respectively, and 37 patients, 31 patients and 7 patients in the median sternal incision group, respectively. There was no statistical difference between the two groups (P=0.102, 0.402, 0.320). The 5-year cumulative progression free survival (PFS) rates of patients with WHO type A, AB, B1, B2, B3 and C thymomas were 100.0%, 100.0%, 95.7%, 81.4%, 67.5% and 50.0%, respectively (P<0.001). The 5-year PFS rates of patients with Masaoka stageⅠ-Ⅳ thymomas were 96.1%, 89.2%, 68.6% and 19.3%, respectively (P<0.001). The 5-year PFS rate was 87.3% in patients with myasthenia gravis (MG) and 78.2% in patients without MG (P<0.001). The 5-year PFS rates of patients with different surgeries were 82.4% and 83.8%, respectively (P=0.904). ConclusionWHO pathological classification and Masaoka stage have significant clinical prognosis suggestive effect. Thymoma patients combined with MG have better prognosis, which suggests early diagnosis and treatment of thymoma are important.
