Abstract ( 290 PDF (524KB) ( 75 )  
Background: Follicular variant papillary thyroid carcinoma (FVPTC) is the most common subset of papillary carcinoma. Lymph-node metastasis (LNM) is one of the main predictors of survival in PTC patients, but we found few data related to the correlation between LNM and FVPTC. We therefore aimed to elucidate the relationship between LNM and survival in patients with FVPTC. Method: Logistic regression models were used to determine the factors associated with LNM. The Cox proportional-hazards model was applied to assess the association between LNM and disease-specific mortality. Kaplan-Meier survival analysis and the log-rank test were used to estimate the disease-specific survival rates in patients with and without LNM. Results: In total, 1418 FVPTC patients were identified. The multivariate logistic regression model showed that age, female sex, being married, tumor size > 4cm and extrathyroidal extension and radiation were predictors of LNM. The multivariate Cox regression model showed that age, multifocality and radiation were risk factors of disease-specific mortality. Especially, LNM (p=0.271) did not independently predict disease-specific mortality. Kaplan-Meier survival analysis and the log-rank method also showed that LNM did not impact survival in FVPTC (p=0.235). Conclusion: Using data in the SEER database from 2004 to 2014, and after multivariate model correction, we found that age, multifocality and radiation were strongly related to disease-specific mortality. It is worth noting that LNM does not impact the survival of FVPTC patients.

Objective: As a Chinese drugs preparation to clear heat and remove toxicity, Shuanghuanglian(SHL)has been widely used, but the clinical efficacy and safety of SHL on chronic pharyngitis remain unclear, especially the application of atomized inhalation of SHL need to be verified. The aim of this study was to evaluate its clinical efficacy and safety for chronic pharyngitis. Methods: From the Cochrane Library, Pubmed, EMbase, Wanfang Datebase, CNKI (China National Knowledge Infrastructure), VIP (Chinese Scientifc Journals Database), CBM (Chinese Biomedicine Database), We got the qualified randomized controlled trials(RCTs) and adopted RevMan5.3 software and the risk of bias tool according to the Cochrane to perform a meta-analysis. Results: Ten RCTs, a total of 950 cases (involving 472 cases in SHL group and 478 in control group) were included. The results showed that the clinical efficacy in SHL group was superior to control group [Chi2=5.61, 95%CI (4.29, 11.43), P<0.05], and four literatures reported no obvious adverse reactions in SHL group. Conclusion: Application of atomized inhalation of SHL may have a potential advantage in treating chronic pharyngitis. However, due to the limitation of the quality and sample size of those studies, the accuracy of the result should be treated with caution, higher standardized researches are required to justify the conclusion.

Abstract ( 179 PDF (493KB) ( 73 )  
Objective: The meta-analysis is to objectively evaluate the efficacy of swaddling in neonates. Methods: Randomized controlled trials (RCTs) and Randomized cross-over design (RCD) about the effects of swaddling in neonates from multiple electronic databases (PubMed, Web of Science, the Cochrane Library, EMBASE, CINAHL,CNKI, Wanfang and VIP) until January 2019. Two investigators independently screened eligible studies, extracted data, and assessed the methodological quality by using the quality evaluation criteria for RCTs recommended by Cochrane Handbook. Then data were analyzed by Rev Man 5.3. Results: A total of 6 papers (4 randomized controlled trials and 2 Randomized cross-over design) with 318 participants were included. The meta-analysis indicated that there was a significant difference on Body Temperature, Heart Rate, crying time, incidence of open eyes and incidence of closed eyes (P<0.05); There was no significant difference in Spo2 level between the two groups (p>0.05). Conclusion: Swaddling bath has little influence on the Body Temperature, Heart Rate, and behavioral response of newborn. And it has no significant effect on maintaining Spo2 level. However it can reduce the stress behavior of the newborn. Due to the limitations of the quality of studies included, multi-centered randomized controlled trial large sample size are needed in the future to evaluate the effects of prone position ventilation on neonatal respiratory distress syndrome.

Abstract ( 161 PDF (477KB) ( 96 )  
Objective: To systematically evaluate the effects of Pilates exercise on balance, walking and lower limbs motor function in stroke patients. Methods: The literature databases such as the Cochrane Library, EMbase, PubMed, Web of Science, Chinese Biomedicine Database (CBM), China National Knowledge Infrastructure (CNKI), VIP Database for Chinese Technical Periodicals (VIP) and Wan Fang database (Wan Fang) were retrieved. Randomized controlled trials (RCTs) regarding the effects of Pilates exercise on balance, walking and lower limbs motor function of stroke patients were retrieved. Data were collected and evaluated independently by two researchers. Then, we adopted RevMan 5.3 software to perform a meta-analysis. Results: A total of 5 RCTs were included, including 182 subjects were chosen. The result showed that compared with the routine care group, Pilates exercise can effectively improve the balance of stroke patients when they have trained eight weeks [MD=4.71, 95%CI (2.14, 7.28), P=0.0003], shorten the time of the Timed Up and Go test (TUG) [MD=-1.63, 95%CI (-2.69, -0.56), P=0.003], increase the stride velocity [MD=3.83, 95%CI (1.43, 6.23), P=0.002]. However, the evidence did not support the effectiveness of Pilates exercise on increasing the score of Fugl-Meyer Assessment-Lower Extremity (FMA-LE) of stroke patients [MD=6.70, 95%CI (-3.46, 16.86), P=0.20]. Conclusion: The findings suggest that Pilates could improve the balance and walking speed of stroke patients. However, there still is the lack of the evidence in improving lower limb function. Due to the limitation of the quality of the included studies. high-quality studies still should be conducted to investigate the effect of Pilates exercise in stroke patients.

92Medical Data Mining    2019, 2 (2): 66-75.   https://doi.org/10.12032/mdm2018019
Abstract ( 121 PDF (2923KB) ( 55 )  
Objective: The protective effects of curcumin on myocardial ischemia-reperfusion were systematically evaluated by analyzing the related literatures of curcumin and myocardial ischemia-reperfusion. Methods: The computer was searched for Wanfang, VIP, China National Knowledge Infrastructure(CNKI), SinoMed, and Pubmed database to find animal experiments on curcumin treatment of myocardial ischemia-reperfusion.The retrieval time is from the establishment of the database to November 2018. Two researchers independently screened the literature based on inclusion and exclusion criteria, extracted the data, and assessed the risk of bias in the included studies. Meta analysis was performed using RevMan 5.3 software. Results: Finally, 9 studies were included for analysis. Meta-analysis showed that the curcumin group can reduce LDH and MDA levels compared with the ischemiar-reperfusion group  (LDH: SMD=-4.75, 95% CI [-6.56, -2.94], P < 0.01, MDA: SMD=-2.27, 95% CI [-3.07, -1.47], P < 0.01), the difference was statistically significant (P<0.01). In the subgroup analysis of different doses of curcumin, different doses of curcumin (0.8, 10, 12.5, 20, 25, 30, 50 mg) were able to reduce LDH content compared with the ischemia-reperfusion group, and the differences were statistically significant. Different doses of curcumin (5,10,20,30,40mg) can reduce MDA content, and the difference is statistically significant; curcumin (0.8mg) group has no statistically significant effect on MDA content (SMD = -0.54, 95% CI [-1.35, 0.28], P = 0.20). The relationship between the content of MDA and the dose of curcumin showed that compared with the curcumin (20 mg) group, the curcumin (40 mg) group could better reduce the MDA content, and the difference was statistically significant (P=0.03). Conclusion: Curcumin can reduce the content of LDH and MDA in myocardial ischemia-reperfusion,  and has a protective effect on myocardium. Moreover,  the ability to reduce the damage is related to the dose of curcumin. However, the sample of the included studies is limited, and this conclusion requires more high-quality experiments to verify.

Abstract 

Objective: To systematically evaluate the efficacy and feasibility of high-flow nasal cannula (HFNC) on patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods: Systematic searches on PubMed, Web of Science, the Cochrane Library, Embase, CBM (Chinese Biomedicine Database), CNKI (China National Knowledge Infrastructure), Wanfang Database and VIP were performed for randomized controlled trials (RCTs) which explored the effects of HFNC on patients with AECOPD. The retrieval time was from the establishment of each database to July 2019. RevMan5.3 software was used for statistical analysis. Results: A total of 12 articles were included, involving 812 patients. The results showed that: (1) Compared with conventional oxygen therapy, HFNC could improve patients' arterial partial oxygen pressure (PaO2) (MD = 12.70, 95% CI (7.00,18.40), Z = 4.37, P < 0.0001), reduce partial arterial blood carbon dioxide (PaCO2) (MD = -10.99, 95% CI (-14.42, -7.55), Z = 6.26, P < 0.00001) and reduce endotracheal intubation rate (OR = 0.19, 95% CI (0.04, 0.93), Z = 2.05, P = 0.04), shorten the hospitalization time (SMD = -0.74, 95% CI (-1.11,-0.37), Z = 3.95, P < 0.0001). (2) Compared with non-invasive positive pressure ventilation, it has fewer adverse reactions (OR = 0.18, 95% CI (0.09, 0.35), Z = 5.08, P < 0.00001) and shorter hospital stay (SMD = -0.57,95% CI (-0.90,-0.23), Z = 3.33, P = 0.0009). Conclusion: HFNC can improve the patients’ hypoxia symptoms and CO2 retention, reduce the rate of tracheal intubation, and alleviate adverse reactions. However, Limited by the quality and region of the included studies, more high-quality are needed to test it.

Abstract 

Purpose: In the present study, we focused on the 46 microRNAs and 719 genes in the microRNA-gene network, reported by us, and aimed to build a research blueprint of feedforward loops and reveal the key TFs in H1N1-infected mouse lung. Method: Based on microRNAs and genes in the microRNA-gene network previously reported by us, we used Jemboss software to find relationships between TFs and microRNAs (or genes), and then built a TF-microRNA-gene network exploiting the interactions between TFs and microRNAs (or genes). Next, we searched the sequences of above genes or microRNAs near the transcription start site (TSS) area, and then used the MatchTM algorithm to predict relevant TFs, and built the TF-Gene-Network. Result: We built a TF-microRNA-gene network and exploreed eight key TFs, namely NF-AT1, GKLF, SRY, SOX10, AML1, MZF1, CRX and myogenin, in the network, and then constructed subgraphs of these eight TFs. Simultaneously, we predicted the possible target genes of microRNAs and identified the feedforward regulation relationship of possible TFs, microRNAs and mRNAs. The results showed that all eight factors with a score greater than 100 were TFs, namely NF-AT1, GKLF, SRY, SOX10, AML1, CRX, myogenin and MZF1. We then constructed subtables of the above eight TFs.Conclusion: In this study, TFs including NF-AT1, GKLF, SRY, SOX10, AML1, MZF1, CRX and myogenin showed the highest score ( > 100) not only in the TF-microRNA-gene network but also in feedforward loops, indicating that these eight TFs play the most important roles in mouse H1N1 influenza virus infection biology.

Abstract 

Objective: This study aims to explore the regularity of syndrome differentiation and treatment of traditional Chinese medicine (TCM) for allergic purpura. Methods: CNKI, Weipu Chinese science and technology database, wanfang medical network database, and Chinese biomedical literature database were searched for eligible studies. Medical records including complete patient personal information, patient symptoms, TCM syndromes, treatment, and medication were included. The data was analyzed using the Chinese medicine heritage support platform provided by the Chinese Academy of Chinese medicine (V2.5). Results: Differentiation of health gas camp blood was the most commonly used method of differentiation of symptoms and signs in famous veteran TCM. The treatment included cooling blood, activating blood circulation, clearing heat and detoxifying toxins, removing blood stasis and stopping bleeding. Honeysuckle, Forsythia suspensa, cicada slough and other drugs were interrelated. Potential drug pair combinations and drug networks showed the basic drug composition of Qingying Decoction. According to the entropy cluster analysis, 28 core drug combination and 12 new formulations were obtained. Conclusion: The regularity of syndrome differentiation and treatment of traditional Chinese medicine for Henoch-Schonlein purpura based on the famous and old TCM doctors was complex. Further researches are still needed.

Abstract 

Objective: This study aimed to collect, sort out and excavate the literature on the diagnosis and treatment of insomnia in Chinese Medical Code, and to explore the law of internal administration of traditional Chinese medicine in the treatment of insomnia. Methods: We used "Chinese Medical Code" as the source of data retrieval, "insomnia", "not sleepy", "no sleeping" and "eye not sleeping" as the key words, and excluded temporary insomnia, physiological insomnia, insomnia caused by other diseases, and excluded other methods such as acupuncture and massage, the medical cases. Prescriptions of insomnia treated with traditional Chinese medicine were screened out. The database was established by using Microsoft excel 2010. Descriptive statistics were used to analyze the frequency, menstruation of nature, taste and efficacy of traditional Chinese medicine. We analyzed the association rules between drugs and mined the rules of prescriptions by the Apriori algorithm in SPSS Modeler 14.1. Results: A total of 147 prescriptions, 138 traditional Chinese medicines, 20 pairs of core drugs, 57 common drug combinations and 3 core pharmaceuticals were included. The basic prescription is:Suan Zao Ren, Bai Zi Ren, Fu Shen, Fu Ling, Yuan Zhi, Dang Gui, Gan Cao (Zhi). Conclusion: In summary, according to the drug analysis above, the main disease of insomnia is in the heart, involving the liver, spleen and kidney. Because it involves different viscera and syndrome, the methods of treatment are also different. However, there is a basic pathogenesis, that’s the loss of mental nourishment. By excavating the law of the use of traditional Chinese medicine in the treatment of insomnia on the Chinese Medical Code, we expect that it can guide the treatment of insomnia.
