Objective To evaluate the feasibility and efficacy of intravascular optical coherence tomography (OCT) in the assessment of plaque characteristics and drug eluting stent deployment quality in the elderly patients with unstable angina (UA) and non-ST segment elevation myocardial infarction (NSTEMI). Methods OCT was used in elderly patients undergoing percutaneous coronary interventions.Fifteen patients, 9 males and 6 females with mean age of 72.6±5.3 years (range 67-92 years) were enrolled in the study. Images were obtained before initial balloon dilatation and following stent deployment. The plaque characteristics before dilation, vessel dissection,tissue prolapse, stent apposition and strut distribution after stent implantation were evaluated. Results Fifteen lesions were selected from 32 angiographic lesions as study lesions for OCT imaging after diagnostic coronary angiography. There were 7 lesions in the left anterior descending artery, 5 lesions in the right coronary artery and 3 lesions in the left circumflex coronary artery. Among them,12 (80.0%) were lipid-rich plaques, and 10 (66.7%) were vulnerable plaques with fibrous cap thickness 54.2±7.3 μm. Seven ruptured culprit plaques (46.7%) were found; 4 in UA patients and 3 in NSTEMI patients. Tissue prolapse was observed in 11 lesions (73.3%).Irregular stent strut distribution was detected in 8 lesions (53.3%). Vessel dissections were found in 5 lesions (33.3%). Incomplete stent apposition was observed in 3 stents (20%) with mean spacing between the struts and the vessel wall 172±96 mm (range 117-436 mm).Conclusions 1) It is safe and feasible to perform intravascular OCT to differentiate vulnerable coronary plaque and monitor stent deployment in elderly patients with UA and USTEMI. 2) Coronary plaques in elderly patients with UA and USTEMI could be divided into acute ruptured plaque, vulnerable plaque, lipid-rich plaque, and stable plaque. 3) Minor or critical plaque rupture is one of the mechanisms of UA in elderly patients. 4) Present drug eluting stent implantation is complicated with multiple tissue prolapses which are associated with irregular strut distributions. 5) The action and significance of tissue prolapse on acute vessel flow and in-stent thrombus and restenosis need to be further studied.

Objective To investigate the possible differences in safety and efficacy between re-use and initial use in patients with ankylosing spondylitis (AS) treated with tumor necrosis factor inhibitors (TNFi). Methods From October 2016 to October 2017, 82 patients with AS who were admitted to the Second Hospital of Lanzhou University were studied. Among them, 57 patients used TNFi for the first time and 25 patients reuse it after the interruption. After 3 months of standardized use of TNF-inhibitor, we compared the efficacy indicators [visual analogue scale/score (VAS), morning stiffness, bath ankylosing spondylitis disease activity index (BASDAI), Bath ankylosing spondylitis functional index (BASFI), Bath ankylosing spondylitis metroloty index (BASMI), ankylosing spondylitis disease activity score (ASDAS), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) 0 and safety events between the two groups. T test and covariance analysis were used. Results The efficacy indexes of the two groups after treatment were significantly improved, the difference was statistically significant (P<0.05) compared with the baseline [Before and after treatment in the first treatment group: ESR: (40±31) mm/1 h, (8±8) mm/1 h, CRP: (28±35) mg/L, (5±9) mg/L, VAS: (6.5±1.6), (2.0 ±1.7), Morning stiff time: (0.6 ±0.4) h, (0.1 ±0.2) h, BASDAI: (5.0 ±1.3) h, (1.6 ±1.2) h, BASFI: (4.1 ±2.3), (1.3±1.3), BASMI: (2.6±2.0), (0.8±1.0), ASDAS: (3.5±0.8), (1.2±0.7); Before and after treatment in the re-use group: ESR: (39 ±33) mm/1 h, (9 ±10) mm/1 h, CRP: (28 ±28) mg/L, (5 ±6) mg/L, VAS: (6.6 ±1.9), (1.6 ±1.0), Morning stiff time:(0.6±0.4) h, (0.1±0.1) h, BASDAI:(5.1±0.8), (1.4±1.4), BASFI (5.1±2.2), (1.3±1.4), BASMI:(3.4 ±1.8), (1.0 ±0.9), ASDAS: (3.6 ±0.8), (1.2 ±0.4)]. But there was no statistical significant difference between the two groups in patients after treatment (P>0.05). Conclusion Patients with AS who re-uses TNFi after discontinuation could achieve the same safety and efficacy as they first use it.

Specnuezhenide(SNZ)is among the main components of Fructus Ligustri Lucidi,which has anti-inflammation,anti-oxidation,and anti-tumor effect.The low bioavailability makes it difficult to explain the mechanism of pharmacological effect of SNZ.In this study,the role of the gut microbiota in the metabolism and pharmacokinetics characteristics of SNZ as well as the pharmacological meaning were explored.SNZ can be rapidly metabolized by the gut microbiome,and two intestinal bacterial metabolites of SNZ,salidroside and tyrosol,were discovered.In addition,carboxylesterase may be the main intestinal bacterial enzyme that mediates its metabolism.At the same time,no metabolism was found in the incubation system of SNZ with liver microsomes or liver homogenate,indicating that the gut microbiota is the main part involved in the metabolism of SNZ.In addition,pharmacokinetic studies showed that salidroside and tyrosol can be detected in plasma in the presence of gut microbiota.Interestingly,tumor development was inhibited in a colorectal tumor mice model administered orally with SNZ,which indicated that SNZ exhibited potential to inhibit tumor growth,and tissue distribution studies showed that salidroside and tyrosol could be distributed in tumor tissues.At the same time,SNZ modulated the structure of gut microbiota and fungal group,which may be the mechanism governing the antitumoral activity of SNZ.Furthermore,SNZ stimulates the secretion of short-chain fatty acids by intestinal flora in vitro and in vivo.In the future,targeting gut microbes and the interaction between natural products and gut microbes could lead to the discovery and development of new drugs.

At present, clinical interventions for chronic kidney disease are very limited, and most patients rely on dialysis to sustain their lives for a long time. However, studies on the gut-kidney axis have shown that the gut microbiota is a potentially effective target for correcting or controlling chronic kidney disease. This study showed that berberine, a natural drug with low oral availability, significantly ameliorated chronic kidney disease by altering the composition of the gut microbiota and inhibiting the production of gut-derived uremic toxins, including p-cresol. Furthermore, berberine reduced the content of p-cresol sulfate in plasma mainly by lowering the abundance of g_Clostridium_sensu_stricto_1 and inhibiting the tyrosine-p-cresol pathway of the intestinal flora. Meanwhile, berberine increased the butyric acid producing bacteria and the butyric acid content in feces, while decreased the renal toxic trimethylamine N-oxide. These findings suggest that berberine may be a therapeutic drug with significant potential to ameliorate chronic kidney disease through the gut-kidney axis.

To unravel the genetic mechanisms of disease and physiological traits, it requires comprehensive sequencing analysis of large sample size in Chinese populations. Here, we report the primary results of the Chinese Academy of Sciences Precision Medicine Initiative (CASPMI) project launched by the Chinese Academy of Sciences, including the de novo assembly of a northern Han reference genome (NH1.0) and whole genome analyses of 597 healthy people coming from most areas in China. Given the two existing reference genomes for Han Chinese (YH and HX1) were both from the south, we constructed NH1.0, a new reference genome from a northern individual, by combining the sequencing strategies of PacBio, 10× Genomics, and Bionano mapping. Using this integrated approach, we obtained an N50 scaffold size of 46.63 Mb for the NH1.0 genome and performed a comparative genome analysis of NH1.0 with YH and HX1. In order to generate a genomic variation map of Chinese populations, we performed the whole-genome sequencing of 597 participants and identified 24.85 million (M) single nucleotide variants (SNVs), 3.85 M small indels, and 106,382 structural variations. In the association analysis with collected phenotypes, we found that the T allele of rs1549293 in KAT8 significantly correlated with the waist circumference in northern Han males. Moreover, significant genetic diversity in MTHFR, TCN2, FADS1, and FADS2, which associate with circulating folate, vitamin B12, or lipid metabolism, was observed between northerners and southerners. Especially, for the homocysteine-increasing allele of rs1801133 (MTHFR 677T), we hypothesize that there exists a "comfort" zone for a high frequency of 677T between latitudes of 35-45 degree North. Taken together, our results provide a high-quality northern Han reference genome and novel population-specific data sets of genetic variants for use in the personalized and precision medicine.
