Predictive validation of existing bleeding and thromboembolic scores in elderly patients with comorbid atrial fibrillation and acute coronary syndrome / 老年心脏病学杂志（英文版）

BACKGROUND@#The validation of various risk scores in elderly patients with comorbid atrial fibrillation (AF) and acute coronary syndrome (ACS) has not been reported. The present study compared the predictive performance of existing risk scores in these patients.@*METHODS@#A total of 1252 elderly patients with AF and ACS comorbidities (≥ 65 years old) were consecutively enrolled from January 2015 to December 2019. All patients were followed up for one year. The predictive performance of risk scores in predicting bleeding and thromboembolic events was calculated and compared.@*RESULTS@#During the 1-year follow-up, 183 (14.6%) patients had thromboembolic events, 198 (15.8%) patients had BARC class ≥ 2 bleeding events, and 61 (4.9%) patients had BARC class ≥ 3 bleeding events. For the BARC class ≥ 3 bleeding events, discrimination of the existing risk scores was low to moderate, PRECISE-DAPT (C-statistic: 0.638, 95% CI: 0.611-0.665), ATRIA (C-statistic: 0.615, 95% CI: 0.587-0.642), PARIS-MB (C-statistic: 0.612, 95% CI: 0.584-0.639), HAS-BLED (C-statistic: 0.597, 95% CI: 0.569-0.624) and CRUSADE (C-statistic: 0.595, 95% CI: 0.567-0.622). However, the calibration was good. PRECISE-DAPT showed a higher integrated discrimination improvement (IDI) than PARIS-MB, HAS-BLED, ATRIA, and CRUSADE (P < 0.05) and the best decision curve analysis (DCA). For thromboembolic events, the discrimination of GRACE (C-statistic: 0.636, 95% CI: 0.608-0.662) was higher than CHA2DS2-VASc (C-statistic: 0.612, 95% CI: 0.584-0.639), OPT-CAD (C-statistic: 0.602, 95% CI: 0.574-0.629) and PARIS-CTE (C-statistic: 0.595, 95% CI: 0.567-0.622). The calibration was good. Compared to OPT-CAD and PARIS-CTE, the IDI of the GRACE score slightly improved (P < 0.05). However, NRI analysis showed no significant difference. DCA showed that the clinical practicability of thromboembolic risk scores was similar.@*CONCLUSIONS@#The discrimination and calibration of existing risk scores in predicting 1-year thromboembolic and bleeding events were unsatisfactory in elderly patients with comorbid AF and ACS. PRECISE-DAPT showed higher IDI and DCA than other risk scores in predicting BARC class ≥ 3 bleeding events. The GRACE score showed a slight advantage in predicting thrombotic events.

Effect on postoperative visual quality with modified ABC design aspheric IOL implantation of cataract patients / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To evaluate the visual quality of patients after modified design aspheric balance curve(ABC)with intraocular lens(IOL)implantation, and to analyze the influencing factors of clinical IOL selection and guide the patient's IOL selection plan. METHODS: A prospective case-control study was conducted in 67 patients(74 eyes)with simple cataract underwent phacoemulsification and foldable aspheric IOL implantation, and 23 eyes in the observation group were implanted with modified design IOL(HOYA Vivinex XY1 group), the control group was implanted with 51 eyes of traditional design IOL(Tecnis ZCB00 group with 27 eyes, IQ SN60WF group with 24 eyes). The uncorrected visual acuity, the best corrected visual acuity, total ocular spherical aberration(SA)and coma under different pupil diameters(3, 4, 5, 6mm), and different pupil diameters(3, 4, 5mm)were measured 1wk and 1mo after operation, the modulation transfer function(MTF)curve, objective scattering index(OSI), intraocular scattered light value Log(s)and contrast sensitivity were obtained. Statistical analysis was performed on the obtained data.RESULTS: The uncorrected visual acuity and best corrected visual acuity at 1wk and 1mo after operation in the three groups were significantly improved compared with those before operation, there was no significant difference among groups(P&#x003E;0.05). The difference of total ocular spherical aberration was statistically significant among the three groups with 5 and 6mm pupil diameter 1wk after operation(P=0.045, 0.037)and there were differences among three groups in pupil diameter of 6mm at 1mo after operation(P=0.042). Comparing the total ocular coma aberration, there were differences among the three groups at 1wk and 1mo after the operation at the pupil diameter of 5 and 6 mm(P&#x003C;0.05). With the increase of pupil diameter at 1wk and 1mo after operation, the total ocular spherical aberration in the HOYA Vivinex XY1 group was lower than that in the other two groups. The MTF values of the Vivinex XY1 group were higher than those that of the control group at each spatial frequency, there was no significant difference among groups(P&#x003E;0.05), and there were no statistical differences in objective scattering index, intraocular scattered light value Log(s)and contrast sensitivity among the three groups(P&#x003E;0.05).CONCLUSION:The improved design of the modified Vivinex IOL can reduce the total ocular spherical aberration and coma, improve the visual quality, and provide a new method for the selection of aspheric IOL.

Toxicity-reducing effect of compatibility of Tripterygium and licorice in animals: systematic review / 中国中药杂志

The aim of this paper was to systematically evaluate the toxicity-reducing effect of Tripterygium-licorice in animal experiments,and also to provide evidence for basic research on the toxicity reduction of Tripterygium wilfordii. The PubMed,EMbase,Web of Science,CBM,CNKI and Wan Fang Databases from their establishment to August 31 th,2018 were searched. Two independent reviewers screened the papers,extracted the data,assessed the risk of bias using SYRCLE assessment tool and conducted Meta-analysis with Rev Man 5. 3 software. A total of 10 papers involving 31 studies were finally included,15 studies of which were used for Meta-analysis. Four studies were included for chronic hepatotoxicity animal model. In experimental group( 34 animals),Tripterygium was administered at dose of 0. 09-0. 1 mg·kg-1·d-1,and glycyrrhizic acid was administered at dose of 90-100 mg·kg-1,both for 2 weeks; in control group( 34 animals),glycyrrhizic acid was replaced with equal volume of normal saline. Eleven studies were included for acute hepatotoxicity animal model. In experimental group( 66 animals),glycyrrhizic acid was administered at dose of 75-480 mg·kg-1 for 7 days,then glycyrrhizic acid was stopped,and Tripterygium began to be administered at dose of 0. 6-1. 0 mg·kg-1 per 24 h or 48 h for a total of 1-2 times; in control group( 66 animals),glycyrrhizic acid was replaced with equal volume of normal saline or corresponding solvent. The results of Meta-analysis showed that in both chronic hepatotoxicity animal model and acute hepatotoxicity animal model,the transaminase levels in the experimental group were lower than those in the control group( P < 0. 05). Subgroup analysis of acute hepatotoxicity animal model showed that the transaminase levels in the experimental group were lower than those in the control group for every subgroup except " glycyrrhizic acid 75 mg·kg-1" subgroup. However,in terms of the mean difference( MD) and confidence interval( CI),there was no significant difference in transaminase decline between each subgroup. Low dose of glycyrrhizic acid( 90-100 mg·kg-1) has a toxicity-reduction effect on chronic hepatotoxicity induced by tripterygium( 0. 09-0. 10 mg·kg-1). Middle and high doses of glycyrrhizic acid( 120-480 mg·kg-1) have a toxicity-reduction effect on acute hepatotoxicity induced by tripterygium( 0. 6-1. 0 mg·kg-1),but with no significant dose-effect relationship.

Research status and progress of non-constant aberration aspherical IOL / 国际眼科杂志(Guoji Yanke Zazhi)

@#With the continuous development of cataract surgery and intraocular lens(IOL), the evaluation of visual quality after IOL implantation has become a research hotspot, and aberration is an important factor that affecting visual quality. After more than 60y of development, IOL has made great improvement in optical design. Due to the fact that conventional spherical IOL has a positive spherical aberration and cannot correct the positive spherical aberration existing in the normal human cornea, it is improved to an aspherical IOL having a negative spherical aberration and a zero spherical aberration. The former can correct the cornea positive spherical aberration, improve the contrast sensitivity and improve visual quality. However, if the optical position does not match, the formation of other higher-order aberrations will have greater impact on visual effects. Although the latter is well tolerated to tilt and decentration, it still cannot compensate for the positive aberration from the cornea. The advent of the non-constant aberration IOL provides a new way for cataract surgeons to solve this problem. In this paper, the concept of aberration, the design principle and advantages and disadvantages of different kinds of aspheric IOL, as well as the observation of clinical application effect of non-constant aberration aspheric IOL are discussed.

Identification and function analysis of target group for cardioprotection of Baoyuan decoction / 中国中药杂志

Baoyuan decoction (BYD) is a well-known traditional Chinese medicine formula for coronary heart disease with Qi deficiency. However, the detailed pharmacological mechanism of BYD is still unknown because of its complicated chemical compositions. In this study, we synthesized a kind of solid beads with benzophenone groups on its surface. Benzophenone can be activated and chemically cross-linked with the C-H bonds of the chemical compositions in BYD (BYD beads) under UV activation. We thus captured all the target proteins from mouse heart tissue lysates by using BYD beads. Based on proteomics analysis, we discovered totally 46 potential binding target proteins, most of which were located in mitochondria. KEGG analysis revealed that these target proteins were mainly associated with TCA cycle and amino acid metabolism signaling pathways, suggesting that the cardioprotection of BYD might be associated with regulating mitochondrial function and energy production. Moreover, JC-1 staining analysis also confirmed the protective effect of BYD on mitochondrial damage. In summary, our findings elucidated the potential mechanism of BYD on cardioprotection through "target fishing" strategy, and further explained its traditional efficacy in the molecular level. In addition, we also provide an approach for investigating the target group of complicated compositions in Chinese herbal formula. This novel method may provide a methodological reference for exploring the pharmacological mechanism of traditional Chinese formula in the future.

Effect of allitridum on remodeling of the transient outward potassium current of ventricular myocytes of spontaneously hypertensive rats / 药学学报

We aimed to study the effect of allitridum (All) on the transient outward potassium current (Ito) of ventricular myocytes of spontaneously hypertensive rats (SHR). Totally 30 male SHRs were randomly divided into three groups: low-dose All group (7.5 mg·kg(-1)), high-dose All group (15.0 mg·kg(-1)) and normal saline group. The other 10 sex and age matched Wistar-kyoto rats (WKY) were also taken as control group (WKY group). All animals received i.p. administration for 8 weeks. The dual enzymatic method was used to separate single ventricular myocyte from animals. Patch-clamp technique was used to record Ito and analyze the effect of All on the current. It was shown that the left ventricular hypertrophy of SHR was reversed significantly by All. Furthermore, the density of Ito was recovered in both high and low dose All groups. The peak current densities of Ito were enhanced from 18.23±3.64 to 25.17±2.86 pA/pF (P<0.01) and 36.47±5.42 pA/pF (P<0.01) at +50 mV by All 7.5 mg·kg(-1) and 15.0 mg·kg(-1), respectively, which was not significantly different with WKY group. The effect was associated with positive shift of the steady-state, close-state inactivation, and shortened recovery from inactivation of Ito. It is concluded that All decreases the remodeling of Ito of ventricular hypertrophic myocytes of SHR.

Remarks on the relationship between deqi and effect of acupuncture / 中国针灸

Acupuncturists have always paid high attention to deqi (needling sensation) in clinical. However, relationship between deqi and curative effect has not been elucidated yet. In order to have a further understanding on effect of deqi on clinical effect, through study on literature associated with deqi since the establishment of People's Republic of China in 1949, it is held that various factors can influence therapeutic effect of acupuncture treatment, including whether needling sensation appears or not, the speed of deqi, the intensity of deqi, different types of sensations as well as propagated sensation along meridians (PSM). Joint launched multidisciplinary researches should be carried out to reveal the influence principle of deqi on acupuncture effect, and to lay foundations for the further studies on mechanism of deqi.

Progression of the study on the acupoints from 2006 to 2010 overseas / 中国针灸

With retrieval of MEDLINE database (from Jan 2006 to Dec 2010) and supplementary search on other important literatures, 29 overseas articles that were in accord with inclusive criteria were included. The results showed that the overseas scholars issued the international standard on human acupoint locations and proposed the localization system of animal acupoint model; discovered the new acupoint structure, characteristic of acupoint microcirculation, the states of the diseases could be specifically reflected through acupoint temperature, electric resistance, pressure and pain threshold, and the specific brainstem reaction could be induced by electroacupuncture at acupoints; verified initially the effect on nausea and vomiting with the related acupuncture methods at acupoints and explained the mechanisms on the local analgesia of acupuncture at acupoints; suggested that a further study should be expected on the low electric resistance property of acupoints and the effect specificity in the treatment of disease. Additionally, they were proposed that the domestic study should focus on the symptom treatment, correct application of logic reasoning, the secondary literature study and international exchange and cooperation. It is indicated that the overseas study has made the great progression on the acupoint locations, morphological structure, biological and physical properties, pathological reaction, stimulation effect, therapeutic effect and mechanism, and it provides the references for the domestic study in terms of study clues and methods.

Progress on research of specificity of acupoint effects during "the 11th five-year" / 中国针灸

With retrieval in CNKI and MEDLINE data base, the articles in Chinese and English that were written by Chinese authors, which were about the specificity of acupoint effects during "the Eleventh Five-Year (2006-2010)", are included. Researchers have studied about the specificity of acupoint effects by cerebral function imaging technique and it turns out that from the perspective of central mechanism, there are differences among aupoint stimulatory effect. The curative effect of acupoints is significantly better than that of nonacupoints, different acupoints have different curative effects, the effect of disease-related acupoints is better than that of unrelated acupoints, those above have intitally proved the existence of specificity of acupoint effects. However, part of the research results need futher summaries, analysis and promotion as well as try to avoid low-level repeat in research design.

Progress on the research of acupuncture's role in anti-early pregnancy in recent 9 years / 中国针灸

Through CNKI retrieval, 40 articles were selected from Medical Journals published between January 2003 and December 2011, and the study designs, intervention methods and conclusions of the articles were analyzed. It turned out that in the area of clinical research, the main usage of acupuncture was assist treatment of artificial abortion and drug-induced abortion: in artificial abortion, acupuncture can play a role in analgesia, artificial abortion syndrome relieving, and cervix dilating, while in the drug induced abortion, acupuncture can play a role in improving completed abortion rate, accelerating foetal sac release, decreasing side effects and regulating postoperative bleeding. In mechanism research, the effect of acupuncture on uterine tissue was revealed in terms of neuroendocrine. Although the certain role of acupuncture in assisting artificial abortion and drug-induced abortion has been confirmed in numerous clinical trials, its mechanism revealing was limited. The further study should focus on improving research method, acupuncture manipulation standardization and stimulation parameters optimization. What's more, the revealing of acupuncture's role in anti-early pregnancy should be emphasized to improve its effectiveness and scientificalness.
