Through several thousand years’ inheritance and development by Chinese people, traditional Chinese medicine (TCM) has formed its unique theoretic system, whose efficacy has been widely accepted. However, because TCM theory focuses on the relationships among syndromes, treatment and efficacy, instead of the cause-and-effect relationship explored by modern natural science, the scientificity of TCM has always been questioned. In recent years, because virtual-world clinical research mode and the concept of “big data” were emphasized, increasing researchers began to put their research emphasis on the correlativity between intervening measures of diseases and outcome indicators. This change and the advancement of computer data mining and analysis technology, bring great opportunities for the further development of TCM theory and practice. This article concluded data mining technology used in TCM diagnosis and treatment in recent years, such as clustering analysis, decision tree, Bayesian network, neural network and multi-instance learning, which showed how to apply these methods to reveal rules of TCM diagnosis and treatment from a large number of TCM syndrome data, find knowledge hidden in data, and show TCM effectiveness supported by data.

Objectives:
. The annual prevalence of chronic rhinosinusitis (CRS) is increasing, and the lack of effective treatments imposes a substantial burden on both patients and society. The formation of nasal polyps in patients with CRS is closely related to tissue remodeling, which is largely driven by the epithelial-mesenchymal transition (EMT). MicroRNA (miRNA) plays a pivotal role in the pathogenesis of numerous diseases through the miRNA-mRNA regulatory network; however, the specific mechanism of the miRNAs involved in the formation of nasal polyps remains unclear.
Methods:
. The expression of EMT markers and Smad3 were detected using western blots, quantitative real-time polymerase chain reaction, and immunohistochemical and immunofluorescence staining. Differentially expressed genes in nasal polyps and normal tissues were screened through the Gene Expression Omnibus database. To predict the target genes of miR-145-5p, three different miRNA target prediction databases were used. The migratory ability of cells was evaluated using cell migration assay and wound healing assays.
Results:
. miR-145-5p was associated with the EMT process and was significantly downregulated in nasal polyp tissues. In vitro experiments revealed that the downregulation of miR-145-5p promoted EMT. Conversely, increasing miR-145-5p levels reversed the EMT induced by transforming growth factor-β1. Bioinformatics analysis suggested that miR-145-5p targets Smad3. Subsequent experiments confirmed that miR-145-5p inhibits Smad3 expression.
Conclusion
. Overall, miR-145-5p is a promising target to inhibit nasal polyp formation, and the findings of this study provide a theoretical basis for nanoparticle-mediated miR-145-5p delivery for the treatment of nasal polyps.

Objective To compare the hemostatic safety and efficacy of a new butterfly femoral artery compression device (FACD) with those of manual compression (MC) in patients undergoing percutaneous peripheral endovascular interventions via femoral artery. Methods A total of 283 patients, who received percutaneous endovascular interventions via femoral artery during the period from September 2016 to December 2017, were enrolled in this study. After endovascular intervention, 167 patients received FACD to make hemostasis (FACD group), and 116 patients received MC hemostasis (MC group) . The patient's comfortableness, time used for hemostasis (min), limb immobilization time (h), and the incidence of vascular complications in both groups were analyzed. Results All 283 patients were included in analysis, the results indicated that the hemostatic success rates in FACD group and MC group were 96.4% (161/167) and 94.0% (109/116) respectively, the difference between the two groups was not statistically significant (P>0.05) . The postoperative Kolcaba Comfort Scale score of FACD group was (85.0 ±11.2) points, which was remarkably higher than (58.4±11.7) points of MC group (P<0.05), the time used for hemostasis in FACD group was (9.2 ±2.2) min, which was strikingly shorter than (18.5 ±2.9) min in MC group (P <0.05) . The limb immobilization time in FACD group was (10.4±2.4) hours, which was obviously shorter than (23.1±4.1) hours in MC group (P <0.05) . The incidence of vascular complications in FACD group was 3.6%, which was dramatically lower than 9.5% in MC group (χ2=4.206, P=0.04) . Conclusion The use of the new butterfly FACD can promptly, safely and effectively stop bleeding of femoral artery puncture site. The new butterfly FACD is superior to MC in shortening hemostatic time and limb immobilization time, in reducing incidence of vascular complications, as well as in improving patient's comfortableness degree.

BACKGROUND AND PURPOSE: Both genetic factors and smoking are associated with ischemic stroke (IS) risk. However, little is known about the potential interaction of these factors. We aimed to assess whether smoking and a positive family history interact to increase the risk of IS. METHODS: The nationwide prospective study recruited 210,000 men and 300,000 women in 2004 to 2008 at ages 30 to 79 years. During 9.7 years of follow-up, we documented 16,923 and 20,656 incident IS cases in men and women without major chronic diseases at baseline, respectively. Multivariable Cox regression models were used to examine associations between family history and IS. Likelihood ratio tests were used to test the smoking-family history interactions on IS. RESULTS: About 67.8% (n=135,168) of men ever smoked regularly compared with 2.7% (n=7,775) of women. Among men, a significant interaction between family history and smoking on IS was observed (P for interaction=0.03), with more pronounced association between family history and IS among ever-regular smokers (hazard ratio [HR], 1.21; 95% confidence interval [CI], 1.16 to 1.27) than among never-smokers (HR, 1.11; 95% CI, 1.01 to 1.23). The association between family history and IS among ex-smokers after more than 10 years of cessation (HR, 1.01; 95% CI, 0.85 to 1.20) appeared similar to that among never-smokers. Among women, a similar but not significant interaction between family history and smoking on IS was observed. Ever-regular smokers who had a family history of stroke had the highest risk of IS. CONCLUSIONS: Among Chinese men, the association of family history with IS was accentuated by smoking, and such accentuation tended to be lowered by cessation.

The cost-effectiveness analysis policy for drugs was institutionalized in Japan since 2019, realizing quantitative adjustment of price across varieties. A hierarchical categorization approach was adopted to select medicines with high expected annual sales. For selected medicines, adjustments were made to the premium and profit components within the existing price structure based on a pre-defined incremental cost-effectiveness ratio (ICER) threshold, effectively resolving the issue of inconsistent criteria and magnitudes caused by subjective judgment. Meanwhile, incentive measures like evaluation exemption or threshold enhancement were granted for specific medicines. Besides, a price adjustment mechanism, which was allowed for upward and downward adjustments, involving tiered ICER threshold and quantified formulas, had been established for the premium and profit components of drug price. In China’s National Reimbursement Drug List (NRDL) access, certain issues remained to be addressed: insufficient clarity in the quantitative mechanism of price formation, incomplete price adjustment measures, and lagging in the communication channels. It is recommended that the following measures could be referred to when further improving the scientificity and fairness of drug pricing during China’s NRDL access, such as enhancing the ICER threshold for medicines catering to special populations, quantifying criteria and extents for price adjustment, granting preferential pricing policies to pharmaceutical companies that present high-quality evidence of effectiveness, preceding communication channels with pharmaceutical companies, as well as exploring a price floor mechanism for the drugs with excessive price reduction.
