Background: Evidence suggests that the rs11615 (C>T) polymorphism in the ERCC1 gene may be a risk factor for gynecological tumors. However, results have not been consistent. Therefore we performed this meta-analysis. Methods: Eligible studies were identified by search of PubMed, MEDLINE and Chinese National Knowledge Infrastructure (CNKI). Odds ratios (ORs) and 95% confidence intervals (CIs) were applied to assess associations between rs11615 (C>T) and gynecological tumor risk. Heterogeneity among studies was tested and sensitivity analysis was applied. Results: A total of 6 studies were identified, with 1,766 cases and 2,073 controls. No significant association was found overall between rs11615 (C>T) polymorphism and gynecological tumors susceptibility in any genetic model. In further analysis stratified by cancer type, significantly elevated ovarian cancer risk was observed in the homozygote and recessive model comparison (TT vs. CC: OR=1.69, 95% CI=1.03-2.77, heterogeneity=0.876; TT vs. CT/CC: OR=1.72, 95% CI=1.07-2.77, heterogeneity=0.995). Conclusion: The results of the present meta-analysis suggest that there is no significant association between the rs11615 (C>T) polymorphism and gynecological tumor risk, but it had a increased risk in ovarian cancer.

Background: In recent years, numerous studies have been performed to investigate the CCND1 G870A gene polymorphism impact on brain tumors susceptibility. Unfortunately, the results of previous studies were inconsistent. Therefore, we performed a meta-analysis to derive a more precise estimation of any association. Materials and Methods: We conducted a search in PubMed, Embase and CNKI covering all published papers up to November, 2013. Odds ratios (ORs) and their 95% confidence intervals (95%CIs) were applied to assess associations. Results: A total of 6 publications including 9 case-control studies met the inclusion criteria. The pooled ORs for the total included studies showed significant association among comparison A vs G (OR= 1.246, 95%CI= 1.092-1.423, p= 0.001), homozygote comparison AA vs GG (OR= 1.566, 95%CI= 1.194-2.054, p= 0.001), heterozygote comparison AG vs GG (OR= 1.290, 95%CI= 0.934-1.782, p= 0.122), dominant model AA/GA vs GG (OR= 1.381, 95%CI= 1.048-1.821, p= 0.022) and recessive model AA vs GA/GG (OR= 1.323, 95%CI= 1.057-1.657, p= 0.015) especially in glioma. Conclusions: CCND1 G870A polymorphism may increase brain tumor risk, especially for gliomas. However, more primary large scale and well-designed studies are still required to evaluate the interaction of CCND1 G870A polymorphism with brain tumor risk.

Background: Studies investigating the association between 2R/3R polymorphisms in the thymidylate synthase 5'-untranslated enhanced region (TYMS 5'-UTR) and gastric cancer risk have generated conflicting results. Thus, a meta-analysis was performed to summarize the data on any association. Methods: Pubmed, Embase, and CNKI databases were searched for all available studies. The strength of association between TYMS 5'-UTR 2R/3R polymorphism and gastric cancer risk was estimated by odds ratios (ORs) with 95% confidence intervals (CIs). Results: Six individual case-control studies with a total of 1, 472 cases and 1, 895 controls were included into this meta-analysis. Analyses of total six relevant studies showed that there was no obvious association between the TYMS 5'-UTR 2R/3R polymorphism and gastric cancer risk. Subgroup analyses based on ethnicity showed 2R of TYMS 5'-UTR 2R/3R contributes to gastric cancer risk in the Asian population ($OR_{Homozygote\;model}$ = 1.71, 95%CI 1.19-2.46, P = 0.004; $OR_{Recessive\;genetic\;model}$ = 1.70, 95%CI 1.18-2.43, P = 0.004). However, the association in Caucasian populations was uncertain due to the limited studies. Conclusions: Our meta-analysis suggests that 2R of TYMS 5'-UTR 2R/3R contributes to gastric cancer risk in the Asian population, while this association in Caucasians populations needs further study.

Objective: Methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms have been reported to be associated with pancreatic cancer, but the published studies had yielded inconsistent results.We therefore performed the present meta-analysis. Methods: A search of Google scholar, PubMed, Cochrane Library and CNKI databases before April 2012 was conducted to summarize associations of MTHFR polymorphisms with pancreatic cancer risk. Assessment was with odds ratios (ORs) and 95% confidence intervals (CIs). Publication bias were also calculated. Results: Four relative studies on MTHFR gene polymorphisms (C667T and A1298C) were involved in this meta-analysis. Overall, C667T(TT vs. CC : OR = 1.61, 95%CI = 0.78 - 3.34; TT vs. CT : OR = 1.41, 95%CI = 0.88-2.25; dominant model: OR = 0.68, 95%CI = 0.40-1.17; recessive model: OR = 0.82, 95%CI = 0.52-1.30) and A1298C(CC vs. AA:OR=1.01, 95%CI=0.47-2.17; CC vs. AC: OR=0.99,95%CI=0.46-2.14; dominant model: OR=1.01, 95%CI = 0.47-2.20; recessive model: OR = 1.01, 95%CI = 0.80-1.26) did not increase pancreatic cancer risk. Conclusion: This meta-analysis indicated that MTHFR polymorphisms (C667T and A1298C) were not associated with pancreatic cancer risk.

Objectives The purpose of this study is to provide clinical evidence of Korean medicine for febrile seizure by review of randomized controlled trials on the effect of TCM (traditional Chinese medicine) for febrile seizure. Methods We searched randomized controlled trials about TCM treatment of febrile seizure from the China National Knowledge Infrastructure (CNKI) (January 2008 to June 2016). The selected literatures were assessed by Jadad scale. Results 40 papers were selected from 160 studies. Analyses of selected studies indicated that the TCM treatment group has significantly higher cure rate for febrile seizure than first aid or western medicine group. The most commonly used herbs were Gardeniae Fructus (梔子), Uncariae Ramulus cum Uncis (鉤藤), Cornus Gazeliae (羚羊角), Margarita (珍珠), Scutellariae Radix (黃芩), Glycyrrhizae Radix (甘草). The most commonly used acupoints were GV26 (人中), LI4 (合谷), KI1 (湧泉), GV20 (百會). There were no serious adverse events reported from the TCM treatment group during the treatment period. Conclusions TCM has been shown as not only effective but also safe treatment on febrile seizure. This finding can be widely utilized in clinical practice and can form the basis for development of clinical practice guidelines in future.

Objectives The purpose of this study is to analyze studies about the effects of topical application of Chinese herbal medicine for allergic rhinitis within randomized controlled trials (RCT). Methods The search database includes KJTK (Korean Traditional Knowledge Portal), OASIS (Oriental Medicine Advanced Searching Integrated system), CNKI (China National Knowledge Infrastructure), PubMed, and EMBASE. We used the following key search terms: "allergic rhinitis", "traditional Chinese medicine", "traditional Korean medicine", "Chinese herbal medicine", "randomized controlled trial", "clinical study", "nasal spray", and "nasal drop" Results Five studies were selected for analysis. Three studies used nasal spray of Chinese herbal medicine and two studies used nasal drops of Chinese herbal medicine for the intervention. Frequently used herbs were Magnoliae Flos (辛夷), Scutellariae Radix (黃芩), Coptidis Rhizoma (黃連), and Astragali Radix (黃芪). For the outcome measures, studies used symptom score, questionnaire of Quality of Life, nasal airway resistance, or laboratory studies. From all 5 studies, it has been shown that topical application of Chinese herbal medicine was effective for improving symptoms of allergic rhinitis. Two out of five studies showed statistical difference between study group and control group. Conclusions This study shows that topical application of Chinese herbal medicine can improve symptoms of allergic rhinitis. Well-designed RCT studies with low risk of bias and studies with outcome measures for assessing the immunomodulatory effects are necessary to confirm these findings.

Objectives The purpose of this study is to analyze clinical studies on effectiveness of herbal medicine in refractory nephrotic syndrome (RNS). Methods We searched the randomized controlled trials (RCTs) with herbal medicine treatment on RNS from the Pubmed, CNKI, OASIS, NDSL, J-stage, and CiNii. The demographic data, duration of illness, intervention, treatment period, outcome, adverse events, and composition of herbal medicine were analyzed for this study. Results 11 RCT studies were selected and analyzed. The children in the control group were given western medicine therapy, and the treatment group was given herbal medicine along with the same western medicine of the control group. The most commonly used herbal medicines were the prescriptions to treat 'Kidney Deficiency with Blood Stasis (腎虛兼瘀血)' which composed of 'Promoting blood circulation (化瘀)', 'Diuresis-inducing (利水)', or 'Heating Yang (溫陽)' medicine based on 'Replenishing Kidney or Spleen (補腎, 補脾)' medicine. In the treatment group, proteinuria and serum lipid was significantly decreased, serum albumin was significantly increased, and total effective rate was significantly higher than the control group. Hypercoagulation and relapse rate was also significantly reduced. Adverse events were significantly lower in the treatment group. Conclusions Herbal medicine treatment on pediatric RNS can be suggested as a new treatment for children who have less response to the conventional therapy. It can also supplement the limitations of the western medicine by reducing adverse events from the steroids and immuno-suppressive agents, and lower the relapse rate as well.

Objectives : The purpose of this study was to review the clinical studies on antihypertensive effects of Oryeong-san. Methods : We searched papers using KTKP, Oasis, CNKI, PubMed, Embase, Science Direct, CINAHL, J STAGE and CiNii, and the key words "Oryeong-san (韓)", "Wuling-san (中)", "Gorei-san (日)", and "Hypertension" were used. Search range included randomized controlled trials (RCTs), clinical reports, reviews and animal experiments. Papers not matched with inclusion criteria were excluded. Results : A total 479 studies were found, with 457 excluded during title and screening. After scanning 22 papers, a final 3 RCTs and 6 case reports were selected and analyzed. In the 3 RCTs, the number of patients varied between 65 and 156. Patients with hypertension were randomized into groups for treatment group and control group. They were all treated with antihypertensive drugs (Vamlodipine Besylate, Benazepril, Perindopril); the treatment group was also given modified Oryeong-san. After treatment, results were that blood pressure was significantly decreased in the treatment group, compared to the control. The other 6 case reports reported that modified Oryeong-san alone or the combination of Oryeong-san plus antihypertensive drugs had beneficial effects on blood pressure. Conclusions : Oryeong-san appears to be effective in improving blood pressure and hypertension-related symptoms. The results of this study could be applied to clinical treatment of hypertension. Further large-scale clinical researches should be conducted.
