BACKGROUND: The association of systemic inflammatory response index (SIRI) with prognosis of coronary artery disease (CAD) patients has never been investigated in a large sample with long-term follow-up. This study aimed to explore the association of SIRI with all-cause and cause-specific mortality in a nationally representative sample of CAD patients from United States. METHODS: A total of 3386 participants with CAD from the National Health and Nutrition Examination Survey (NHANES) 1999-2018 were included in this study. Cox proportional hazards model, restricted cubic spline (RCS), and receiver operating characteristic curve (ROC) were performed to investigate the association of SIRI with all-cause and cause-specific mortality. Piece-wise linear regression and sensitivity analyses were also performed. RESULTS: During a median follow-up of 7.7 years, 1454 all-cause mortality occurred. After adjusting for confounding factors, higher lnSIRI was significantly associated with higher risk of all-cause (HR = 1.16, 95% CI: 1.09-1.23) and CVD mortality (HR = 1.17, 95% CI: 1.05-1.30) but not cancer mortality (HR = 1.17, 95% CI: 0.99-1.38). The associations of SIRI with all-cause and CVD mortality were detected as J-shaped with threshold values of 1.05935 and 1.122946 for SIRI, respectively. ROC curves showed that lnSIRI had robust predictive effect both in short and long terms. CONCLUSIONS SIRI was independently associated with all-cause and CVD mortality, and the dose-response relationship was J-shaped. SIRI might serve as a valid predictor for all-cause and CVD mortality both in the short and long terms.

Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

Chinese patent medicine (CPM) is an important part of traditional and Chinese medicine (TCM). Its quality has direct impact on the safety and effectiveness of clinical use. The quality standard is the pivotal approach to guarantee the quality of CPM. Due to the complex material basis, multitudinous quality influencing factors and unveiled active ingredients, dose-effect relationship and action mechanism, the investigation on quality standard faces many difficulties. This paper surveys the current quality status of CPM and the general situation of CPM standards. At present, the dosing problem has the crucial impact on the quality of CPM. The current quality standard system of CPM is confirmed and the limitations are indicated. Based on the above analysis, the principles and considerations on investigation of quality standard are proposed as follows: ① Adhere to safety as the bottom line, strengthen the risk-control ability of the standard of CPM; ② Adhere to theory of TCM and comprehensive quality, improve the integrative control level of the CPM standard; ③ Emphasize technological development and innovation, promote the quality control competence of CPM standard; ④ Facilitate planning and coordination, optimize the management of the CPM standard system; ⑤ Reinforce investigation on evaluation method, develop grade evaluation standard, accelerate high-quality development of CPM. Finally, the future perspective on investigation of CPM quality standard is prospected.

AIM: To investigate the effect of modified Zhujing pill on retinal autophagy in mice with form deprivation myopia.METHODS: Thirty C57BL/6 mice were randomly divided into a negative control group, a myopia model group and a traditional Chinese medicine intervention group, with 10 mice in each group. Except for the negative control group, all mice in the myopia model group and the traditional Chinese medicine intervention group used translucent EP tubes to cover their right eyes to make a form deprivation myopia(FDM)model; The traditional Chinese medicine intervention group gavage Zhujing pill modified suspension 0.546g/(kg·d)(0.15mL/d), the negative control group and the myopia model group were given an equal amount of normal saline(0.15mL/d)for 4wk. At the beginning and the end of the experiment respectively, the right eye diopter of the mouse was measured with a strip retinoscope, measurement of the axial length of the right eye of mouse by A-ultrasound. At the end of the experiment, the right eyes of all mice were taken for detection, and immunofluorescence method was used to locate and detect the activity and migration of the retinal microglia marker(Iba1); Transmission electron microscope observation of autophagosome formation in retinal pigment epithelial cells; Western Blot, real-time fluorescent quantitative PCR(q-PCR)to detect the autophagy marker LC3Ⅱ and p62 protein quantitative and gene expression in retinal tissues.RESULTS: At the end of the experiment, the refractive power of the right eyes of mice showed that the myopia model group and the traditional Chinese medicine intervention group formed relative myopia, the myopia model group and the traditional Chinese medicine intervention group were significantly lower than those of the negative control group(all P<0.01). At the end of the experiment, the axial length of the myopia model group and the Chinese medicine intervention group were significantly increased compared with the negative control group(P<0.01). Immunofluorescence method for locating and detecting Iba1 showed that the average optical density of Iba1 in the retina of the myopia model group increased the most obviously, followed by the increase in the negative control group, and the decrease in the traditional Chinese medicine intervention group. Compared with the negative control group, the myopia model group increased significantly(P<0.05), and the traditional Chinese medicine intervention group was significantly lower than the myopia model group(P<0.05). It was found that Iba1 migrated to the ganglion cell layer in the myopia model group and the traditional Chinese medicine intervention group. Transmission electron microscopy showed that autophagosomes were observed in the retinal pigment epithelial cells of the myopia model group and the Chinese medicine intervention group. The results of Western Blot and q-PCR showed that the expression of LC3Ⅱ and p62 increased most obviously in the traditional Chinese medicine intervention group, followed by the myopia model group, and the negative control group was the lowest.CONCLUSION: The results of the study show that modified Zhujing pill may enhance retinal autophagy in mice with FDM by inhibiting the activation of microglia.

Objective:To evaluate the effect of ionizing radiation on chromosome aberration of peripheral blood lymphocytes in children with vascular interventional procedure.Methods:The chromosome aberration of peripheral blood lymphocytes was analyzed before and after vascular interventional procedure to assess the effect of low-dose ionizing radiation on chromosomes. Peripheral blood (PB) was collected using heparin as an anticoagulant from 26 patients before and after (within 10 minutes) vascular interventional surgery. Informed consent was obtained from the patients′ parents.Results:Dicentric + centric ring (dic+ r) formation increased significantly ( U=647, P<0.01) in peripheral blood lymphocytes of children after interventional operation. No correlation was observed between the rate of dic+ r and the cumulative dose (CD), dose area product (DAP), age, body weight, gender and the estimated effective dose E ( P>0.05). There was no significant difference in dic+ r rate of children between different genders, ages and lesion sites ( P>0.05). The dic+ r rate after interventional operation exceeded 40×10 -3 in 4 of 26 cases with the highest of 95.83×10 -3. Conclusions:The ionizing radiation during children′s vascular interventional procedure might lead to the increase of chromosome aberration of peripheral blood lymphocytes and some children are abnormally sensitive. Great attention should be paid to the justification and radiation protection during interventional procedure for children.

Sesquiterpene pyridine alkaloids are important components in Tripterygium plants, possessing a wide range of pharmacological activities, such as anti-inflammation immunosuppression, anti-tumor, anti-virus, and deinsectization, and are of great research value. They are composed of highly oxidized dihydro-β-furansquiterpene and pyridine dicarboxylic acid through ester bonds. According to the structural characteristics of pyridine dicarboxylic acid fragments, they can be divided into various structural subtypes. Up to now, more than 110 sesquiterpene pyridine alkaloids have been isolated and identified from Tripterygium plants. This study reviewed the structural features and spectral(i.e., UV, IR, MS, and NMR) characteristics of sesquiterpene pyridine alkaloids and summarized the structural elucidation process in detail to provide references for their further research and development.

To systematically evaluate the clinical efficacy and safety of Danhong Injection combined with conventional therapy in improving diabetes mellitus complicated with coronary heart disease. Based on the online literature database(CNKI, Wanfang, VIP, PubMed, Web of Science, Cochran Library), the Chinese and English papers about the randomized controlled trial(RCT) of Danhong Injection in the treatment of diabetes mellitus complicated with coronary heart disease were searched comprehensively from the establishment of the databases to January 1, 2020. The papers were screened strictly according to the inclusion and exclusion criteria. Based on Jadad scale, the risk assessment of literature was carried out, and Meta-analysis was performed by STATA 12.0 software. Seventeen RCTs were included, involving 1 453 patients. The results of Meta-analysis showed that the combination of Danhong Injection and conventio-nal treatment could improve the clinical comprehensive effective rate(RR=1.47, 95%CI[1.38, 1.58], P<0.000 1), electrocardiogram(ECG) efficiency(RR=1.30, 95%CI[1.16, 1.46], P<0.000 1), efficiency of the angina pectoris(RR=1.41, 95%CI[1.25, 1.58], P<0.000 1), cholesterol level(SMD=-1.05, 95%CI[-1.95,-0.16], P=0.02), low-density lipoprotein(LDL) level(SMD=-0.50, 95%CI[-0.79,-0.21], P<0.000 1), coronary angina attack frequency(SMD=-3.71, 95%CI[-4.05,-3.36], P<0.000 1) and duration of angina pectoris(SMD=-2.96, 95%CI[-3.25,-2.66], P<0.000 1), with statistically significant differences. But the differences in fasting plasma glucose(FPG)(SMD=-0.19, 95%CI[-0.45, 0.08], P=0.16), plasma glucose of two hours after meal(2 hPG)(SMD=0.19, 95%CI[-0.11, 0.49], P=0.22), and high-density lipoprotein(HDL) level(SMD=0.10, 95%CI[-0.30, 0.49], P=0.62) after treatment were not statistically significant. Compared with the control group, there was no significant difference in adverse reactions(SMD=-2.96, 95%CI[-3.25,-2.66], P=0.75). The existing evidence shows that the combination of Western medicine and Danhong Injection can improve the clinical effect for diabetes mellitus complicated with coronary heart disease and has no obvious adverse reactions. However, due to the low level of overall literature evidence, high risk and some kind of publication bias, it still needs more high-quality randomized controlled trials and low-bias studies for further verification.
