Objective To study the related risk factors for recurrence of venous thromboembolism （VTE）. Methods The literatures about the related factors for recurrence of VTE were searched. The relationships between the factors and recurrence of VTE were determined by meta-analysis. Results A total of 12 literatures were included. The results of meta-analysis showed that factors such as males， age＜50 years old， malignant tumor， and antiphospholipid syndrome related with the recurrence of the first VTE after treatment， but there were no correlation between the recurrence of VTE， the type of first VTE， and causes of VTE. Conclusions The recurrence of VTE correlate with various factors. In order to avoid the recurrence of VTE， the patients with the risk factors for recurrence of VTE should be appropriate to extend the duration of anticoagulation
Microsurgery has always been the main treatment for large vestibular schwannomas. With the progress of microsurgical technique and neuroimaging, the application of the intraoperative physiological monitoring technology, as well as the popularization of the concept of minimally invasive neurosurgery, the current development trend of surgery for vestibular schwannomas is to realize both the maximal tumoral resection and the maximal preservation of facial nerve function, which puts more emphasis on the improvement of quality of life. It is still a challenge for neurosurgeons to resect the tumor to the maximum extent and preserve the nerve function as well. In view of this background, the strategy of " near-total resection” and " subtotal resection” combined with stereotactic radiotherapy has been more and more accepted in the past years. However, as a neurosurgeon, the ultimate goal should be " gross-total resection of tumor” and preservation of the nerve function as well. For those tumors severely adherent to neurovascular structure, " near total resection” might be a rational choice. Meanwhile, long-term follow-up should be conducted to clarify the biological behavior of tumor residues, as well as the necessity and long-term effect of stereotactic radiotherapy.
Objective To evaluate the effectiveness of combination therapy with lamivudine (LAM) and hepatitis B immunoglobulin (HBIG) versus LAM monotherapy in prevention of hepatitis B virus recurrence after liver transplantation. Methods Databases including MEDLINE (Ovid), PubMed, EMbase, Cochrane Central Register of Controlled Trials (CENTRAL), CBM, VIP, and CNKI were searched up to Dec. 2008. Clinical trials including randomized controlled, non-randomized concurrent-control and case-control studies about combination therapy with HBIG and LAM versus LAM monotherapy in prevention of hepatitis B virus recurrence after liver transplantation were screened. Trial selection and data extraction were conducted by two reviewers independently. Meta-analysis was performed using RevMan 5.0.18 software. Results Eleven non-randomized concurrent-control studies involving 1 421 patients (1 035 patients in combination therapy group, and 386 patients in LAM monotherapy group) were included. The results of meta-analyses showed: Compared with LAM monotherapy group, the risks of hepatitis B virus recurrence, YMDD mutation, and death associated with HBV recurrence were significantly reduced by 73% (RR=0.27, 95%CI 0.20 to 0.37, Plt;0.000 01), 72% (RR=0.28, 95%CI 0.15 to 0.53, P=0.000 01), and 79% (RR=0.21, 95%CI 0.09 to 0.49, P=0.000 3) respectively in combination therapy group after liver transplantation; overall survival rates of both recipients and grafts in combination therapy group were similar to LAM monotherapy group (RR=1.03, 95%CI 0.95 to 1.11, P=0.51; RR=1.04, 95%CI 0.97 to 1.12, P=0.26). Conclusion Current evidence indicates that compared with LAM monotherapy, combination therapy with LAM and HBIG could reduce the risks of hepatitis B virus recurrence, YMDD mutation, and death associated with HBV recurrence after liver transplantation.
Objective To investigate the recurrence of intrahepatic bile duct stones and study the relations to the primary intrahepatic stones.Methods One hundred and twenty nine patients who experienced complete lithotomy were followed up for 2-10 years. Results Thirty five cases had the recurrence of intrahepatic stones at 49 sites (27.13%). The recurrent stones were found at following sites: 13 at left duct, 12 right duct , 8 left medial segment, 6 right anterior segment, 4 right posterior segment, 3 left lateral segment, 3 caudate. Nine cases were asymptomic, 16 cases had slight symptoms and 10 cases suffered from the serious attacks of stones. The time of recurrence was from 2 to 9 years (5.49±2.25 years) after surgery. The recurrent rate was 27.13% in our group. Conclusion The recurrence of intrahepatic stones also developed at several sites in the liver. The recurrence of intrahepatic stones had a tendency to develop at the primary sites. The recurrence of intrahepatic stones may be asymptomic and most patients suffered from slight attack. Liver resection is the best way to prevent the recurrence from intrahepatic stones.
Objective To study the effect of Huaier granule on the recurrence and metastasis of hepatocellular carcinoma (HCC) and immune rejection in the postoperative patients with liver transplantation for HCC. Methods Twenty-eight patients of liver transplantation for HCC who had taken Huaier granule orally for more than 6 months from September 2001 to March 2007 in West China Hospital were included as treatment group, and other 56 patients of liver transplantation for HCC who didn’t take any Huaier granule in the same time were included as the control group according to the same stage of TNM, degree of tumor differentiation (Edmondson grading) respectively with the treatment group. The method of retrospective cohort study was used to compare the incidence of immune rejection and the 6-month, 1-year, and 2-year recurrence and metastasis of HCC, disease free survival rate, and survival rate between two groups after 2 years’ follow-up beginning from the date of surgery. Results The 6-month, 1-year, and 2-year tumor recurrence and metastasis incidences in treatment group were 14.3%, 32.1%, and 39.3% respectively, which were 23.2%, 32.1%, and 50.0% respectively in control group, and the 2-year tumor recurrence and metastasis incidence of the treatment group was lower than that of the control group. The 6-month, 1-year, and 2-year disease free survival rates in treatment group were 85.7%, 67.5%, and 60.0% respectively, which were 76.7%, 67.6%, and 49.3% respectively in control group, and the 2-year disease free survival rate of treatment group was higher than that of the control group. The 6-month, 1-year, 2-year survival rates in treatment group were 92.9%, 78.6%, and 67.9% respectively, which were 89.3%, 75.0%, and 62.5% respectively in control group. But the 2-year tumor recurrence and metastasis incidence (P=0.353), 2-year disease free survival curve (P=0.386), and 2-year survival curve (P=0.620) were not significantly different between two groups. The incidence of immune rejection was 14.29% in the treatment group and 16.07% in the control group, which was not significantly different between the two groups (P=0.831). Conclusions Huaier granule can increase the 2-year tumor-free survival rate and restrain the recurrence and metastasis of HCC, and does not increase the incidence of immune rejection. Huaier granule as a treatment of HCC in patients with liver transplantation is safe and effective.
ObjectiveThe purpose of this study was to investigate clinical aspects as risk factors for seizure recurrence in patients with post-stroke epilepsy. MethodsDuring January 2010 to April 2016, patients admitted into Department of Neurology, West China Hospital were retrospectively selected. Inpatients diagnosed as epilepsy following stoke and attending our follow-up were participated in this study. Logistic regression model was used to analyze the risk factors of seizure recurrence. ResultsWe included 105 patients with diagnosis of post-stroke epilepsy, among them, 59.0% were male and the median age was 72 years. Median time from stroke onset to seizure attack was 180 days. Approximately 80% patients received antiepileptic drugs(AEDs). During 720 days follow-up period, 70% patients reported without seizure attack. Risk factors significantly associated with seizure recurrence were younger age [OR=3.03, 95 % CI(1.19, 7.76), P=0.02], poor modified Rankin Scale score [OR=3.01, 95 % CI(1.1, 8.18), P=0.03] and using more than two kinds of AEDs [OR=3.85, 95 % CI(1.3, 11.18), P=0.01]. ConclusionsIn the clinical course of post-stroke epilepsy, clinicians should realize the management for primary disease to alleviate stroke sequel and select rational AEDs to reduce seizure recurrence.
ObjectiveTo compare the efficacy and safety of Huaier and Sorafenib in treatment of small hepatocellular carcinoma(HCC)following radical resection. MethodsEighty-two patients with small HCC accepted radical liver resection and then taken Huaier or Sorafenib were collected retrospectively. These patients were divided into Huaier group(51 cases)and Sorafenib group(31 cases)according to the different administration drugs after operation. The baseline characteristics, tumor characteristics, survival rate, tumor recurrence rate, and side effects were compared between two groups. Results①There were no significant differences on the baseline demographic characteristics, liver function, and tumor characteristics between two groups(P > 0.05).②The overall survival rate and tumor-free survival rate had no significant differences between the Huaier group and the Sorafenib group(P=0.737, P=0.699).③The rate of recurrence or metastasis had no significant difference between the Huaier group and Sorafenib group(37.3% versus 32.3%, P=0.648). The most common site of the recurrence or metastasis was the liver and the lung followed.④There were only 5 cases suffered side effects after taking Huaier and no case needed Huaier discontinuance. However, 11 cases suffered side effects after taking Sorafenib and 3 cases needed Sorafenib discontinuance, and the rate of the side effect in the Sorafenib group was much higher than that in the Huaier group(35.5% versus 9.8%, P=0.026). ConclusionFor the small HCC who accepted radical liver resection, Huaier seems to be an effective and safe drug.
Objective To analyze the effects and recurrence rate of single miconazole and the miconazole plus living preparation of lactobacillus for the treatment of the uncomplicated vulvovaginal candidiasis. Methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 4, 2008) MEDLINE (1966 to January 2009); PubMed (1966 to January 2009); EMbase (1966 to January 2009); CNKI (1966 to January 2009), and the Chinese Biomedicine Database (CBM) (1966 to January 2009) to identify randomized controlled trials of single miconazole versus the miconazole plus living preparation of lactobacillus.The quality of the included trials was assessed. RevMan 5 software was used to conduct meta–analysis. Results Eight trials involving 5 156 patients were included in the effect analysis. Meta-analysis showed miconazole plus with living preparation of lactobacillus was better compared with just miconazole (RR=0.96, 95%CI 0.92 to 1.00, Z=2.12, P=0.03; RR=0.92, 95%CI 0.85 to 0.99, Z=2.17, P=0.03).Seven trials involving 4 852 patients were included in recurrence rate analysis. Meta-analysis showed miconazole plus living preparation of lactobacillus had lower recurrence rate compared with single miconazole (RR=3.72, 95%CI 1.94 to 7.13, Z=3.97, Plt;0.000 1; RR=12.85, 95%CI 8.27 to 19.96, Z=11.37, Plt;0.000 01). Conclusion Currently available evidence shows that the effect in the combined group is better, and the recurrence rate is lower.
ObjectiveTo determine the risk factors for recurrence of hepatocellular carcinoma (HCC) after orthotopic liver transplantation (OLT). MethodsThe clinical data from seventysix consecutive HCC patients who underwent OLT were retrospectively analyzed. The patients were divided into nonrecurrence 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 oneyear 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 antitumor therapy shall be given as soon as possible.
Objective To evaluate the prognostic and pathobiologic significance of DNA content. Methods DNA content was conducted on 140 hepatocellular carcinoma patients by flow cytometry. Cancer recurrence was followed up after the patients were discharged. The statistical software used was SPSS. Results DNA ploidy did not correlate with clinicobiologic features, except with the age of the patients (Ｐ＜0.05), tumor size and AFP level (Ｐ＜0.01). The mean following up time of the patients with diploid was 31.2 months. The recurrence rate was 23.1%. In aneuploid group the mean following up time was 22.6 months. The recurrence rate was 50.0%. Ploidy correlated significantly with recurrence rate, the recurrence rate for patients with aneuploid were significantly higher than for those of diploid (Ｐ=0.013), also the recurrence rate of aneuploid within one year (37.9%) was much higher than that of diploid (4.3%) Ｐ=0.002. In a Logistic multivariate analysis of DNA content, the grade of cirrhosis severity and the tumor size were considered to be independent factors that related with recurrence. Conclusion FCM DNA analysis of radically resected HCC is a simple and valid method to predict the recurrence.
