ABSTRACT
Objective: To investigate the chemical constituents of the barks and stems of Melaleuca alternifolia and its antitumor activities. Methods: The chemical constituents were separated and purified consecutively by silica gel, Sephadex LH-20 column chromatography, recrystallization as well as preparative HPLC. Their structures were determined by physicochemical properties and spectral analyses. Furthermore, the cytotoxicity of some compounds against PC-9 (human non-small cell lung cancer cell line), HT29 (human colon cancer cell line) and MCF-7 (human breast cancer cell line) were tested by CCK8 method. Results: Eleven compounds were isolated and identified as ursolic acid 3-O-β-cis-caffeate (1), ursolic acid 3-O-β-trans-caffeate (2), tricontyl ferulates (3), 3-O-acetyl-11(12)-en-urs-28,13β-olide (4), 3-O-acetyl-ursolic acid (5), tricontyl caffeate (6), ursolic acid (7), n-nonacosanol (8), urs-12(13)-en-3-one-28-oic acid (9), 3β-O-acetyl-11α,12α-epoxy-oleanane-28,13β-olide (10), and betulin (11). Conclusion: Compound 1 and 2 are cis-trans isomers. Compound 1 is isolated from natural product for the first time, all the compounds are isolated from this plant for the first time except for compound 11. Compound 1 exhibited moderate inhibited effect on the proliferation of three human cancer cell lines.

Objective@#To evaluate the effect and implementation of auricular acupressure therapy (AAT) in the treatment of acute and chronic non-cancerous pain.@*Methods@#Computer search China Knowledge Network, China Biomedical Literature Disc (CBM), Wanfang Database, Weip Chinese Science and Technology Journal Database, PubMed, Web of Science, EMbase, Ebsco, Cochrane databases, a randomized controlled trial of AAT in the treatment of acute and chronic non-cancerous pain was included. The main outcome of AAT treatment for pain was pain intensity and analgesic drug use.@*Results@#Of the 29 studies included, 93.1% (27/29) indicated that AAT was effective in relieving pain and/or reducing the amount of analgesic drugs; 15 and 12 of them were for acute and chronic non-cancerous pain, respectively. In the positive study with specific information description, 100% (27/27) selected the acupoints of the nervous system, 70.4% (19/27) chose the acupoints corresponding to the pain site, and 92.6% (25/27) used the seeds of the king to retain the seeds. Bean material, 81.0% (17/21) was self-administered by adult patients after successful mission; 12/13 of acute pain studies in AAT lasted for 7 days, 8/11 of chronic non-cancer Sexual pain treatment ranged from 14-28 days; 12/25 of the study was pressed 3-4 times/d, and 36.0% (9/25) of the study lasted 2-5 minutes per test; 16/17 The study used "Deqi" as the appropriate standard for pressing.@*Conclusion@#The included studies have shown that AAT can effectively alleviate 88.2% (15/17) of acute pain and 100% (12/12) of chronic non-cancerous pain. AAT can be performed with auricular acupoints and pain points corresponding to auricular points. The seed is not kept as a pressed bean material, and the adult patient himself is pressed to take the patient′s "getting gas". The duration of AAT is related to the type of pain. Although there is no uniform data on the number of auricular compressions/d and the length of each compression, there is a certain tendency.

ABSTRACT
0bjective To translate and revise《knowledge and attitudes survey regarding pain》(KASRP)(2014), and to test the reliability and validity of the Chinese version of KASRP (2014) and to conduct application testing. Methods Compared with the original English versions of KASRP 2014 and 2008 , the adjusted or newly added items were translated into Chinese through repeated review process, and 140 nurses were conveniently sampled for questionnaire survey. At the same time, 35 subjects were repeatedly measured at intervals of 3 weeks.The internal consistency coefficient and the test-retest were used to assess the reliability , and the content validity and construct validity were used to assess the validity. Results The total Cronbach α coefficient of the questionnaire was 0.717; the test-retest reliability was 0.765; accumulating contribution rate of 14 factors was 67.815% ; the expert evaluation result was: the average score of 4 items among 6 different items was 5 points, which was"extremely applicable"; the average score of 2 items was≥4 points, which was "applicable". The number of correct answers for the respondents was 12-27, and the average answer was 19.28 ± 3.11. The answer rate was between 29% and 66% , with an average of (47 ± 8)% . Conclusion The Chinese version of KASRP (2014) has good reliability and validity and application results.

ABSTRACT
Molecular imprinting technique (MIT) involves the synthesis of polymer in the presence of a template to produce complementary binding sites in terms of its size, shape and functional group orientation. Such kind of polymer possesses specific recognition ability towards its template molecule. Despite the rapid development of MIT over the years, the majority of the template molecules that have been studied are small molecules, while molecular imprinting of proteins remains a significant yet challenging task due to their large size, structural flexibility and complex conformation. This review, we summarized the research findings over the past years, and discussed the nano-reinforcing materials used to prepare molecular imprinting of proteins and the perspective of these nano-reinforcing materials.
