Objective:To analyze the effect of Maixuekang Capsule on the treatment outcome of coronary heart disease (CHD) by propensity score.Methods:Based on the electronic medical record database of 22 large-scale tertiary hospitals nationwide, this study matched the coronary heart disease patients using and not using Maixuekang capsule according to a certain standard (1∶1). After matching, there were 2 464 cases in the patients group (group A) and the patients group (group B). In the database, the recombination of " recovery" and " improvement" is defined as effective treatment, and " invalid" , " death" and " other" are combined as ineffective treatment population. The effectiveness of the two groups after the re combination is compared by propensity score.Results:The results of χ 2 test showed that the difference between the two groups was statistically significant ( P<0.05) without controlling the confounding factors, and the treatment effect of group A was better than that of group B. In order to further observe the difference between the two groups, three logistic regression analysis methods were used to analyze, which showed that the regression coefficient was >0, and there was statistical significance ( P<0.01). Conclusions:The therapeutic effect of Maixuekang capsule on coronary heart disease is higher than that of patients without the drug.

Objective To estimate the value of multi-modal guiding in transrectal ultrasound-guided prostate targeted biopsies (TB) in the biopsy naive patients.Methods From June 2016 to December 2017,178 patients with suspicious prostate cancer were retrospectively evaluated.The age of patients was 54-87 years(median 70 yesrs).Serum PSA level before biopsy was 1.5-95.0 ng/ml (median 13.2 ng/ml),in which 70 cases with PSA ＜ 10 ng/ml,58 cases 10-20 ng/ml,and 50 cases ＞ 20 ng/ml.All patients underwent transrectal ultrasound (TRUS),real-time tissue elastography (RTE) and contrast-enhanced ultrasonography(CEUS).All positive sites on imaging undergoing two-core TB and 10 core-systematic biopsy (SB).The detection rates and positive rates of biopsy for any cancer (PCa) and clinically significant prostate cancer (CsPCa) were compared between TB and SB.Pathological findings of each biopsy core was analyzed for Gleason grade and the single-core length of prostate cancer.Results The total detection rate for PCa was 48.8％ (87/178).The diagnostic accuracy of PCa did not significantly differ between TB 35.5％ (63/178) and SB 42.8％ (76/178) groups.There was no significant difference between the proportion of CsPCa in TB group and SB group [80％ (50/63) vs.66％ (50/76),P =0.21].TB had an obvious higher single-core positive rate for prostate cancer 60.6％ (449/740) and an obvious higher singlecore positive rate for high-risk prostate cancer [10.3％ (76/740)] than SB [29.7％ (530/1 780) and 5.5 ％ (98/1 780)],with statistically signficant difference (P ＜ 0.001,P =0.002).TB also had a higher single-core length of prostate cancer than SB [6.80 (0.20-15.00) mm vs.5.50 (0.06-18.00) mm,P ＜0.05].Conclusions This study revealed a similar rate of prostate cancer detection between multi-modal guiding in transrectal ultrasound-guided prostate targeted biopsies (TB) and 10 core-systematic biopsy (SB).TB maybe tend to detect higher proportion of high-risk PCa.

Cinnamomi Ramulus and Alismatis Rhizoma are commonly used in the treatment of external-contraction diseases. Cinnamomi Ramulus is pungent， sweet， and warm， with the effects of ventilating lung and dispersing cold， warming Yang and transforming Qi， and promoting water and liquid flow from Taiyang meridian to remove dampness. Alismatis Rhizoma is sweet and cold， with the effects of draining dampness and promoting urination， regulating the waterway， removing water retention in lung， and promoting urination to remove dampness and heat. Herbal pairs are extracted from the accumulated experience of medical practitioners over the ages in the use of medicines and have been proved by clinical application to be composed of simple and effective combinations for specific diseases. The herb pair Cinnamomi Ramulus-Alismatis Rhizoma is an important part in ancient classic formulas such as Wulingsan. Both herbs play a role in draining dampness and promoting urination， warming Yang and transforming Qi， being a representative herb pair used for treating external-contraction exterior syndrome and water retention inside. The review of ancient medical publications revealed that there were a large number of compound formulas containing Cinnamomi Ramulus-Alismatis Rhizoma for dispersing cold and removing dampness， which were widely used for thousands of years in clinical practice. Modern pharmacological studies have shown that the active pharmacological components of Cinnamomi Ramulus （cinnamaldehyde and cinnamic acid） and Alismatis Rhizoma （alisol A and 23-acetate alisol B） have anti-inflammatory， antiviral， and immunoregulatory effects and high safety. Qingfei Paidu decoction containing this herbal pair played an important role in fighting against COVID-19. Despite the extensive pharmacological studies on Cinnamomi Ramulus and Alismatis Rhizoma， few studies have been carried out regarding this herb pair. This paper summarizes the traditional Chinese medicine knowledge about Cinnamomi Ramulus and Alismatis Rhizoma in the treatment of external-contraction diseases and summarizes the chemical composition， pharmacological effects， toxicology and other aspects of the two herbs before and after compatibility， aiming to provide a reference for further research and clinical application.
