This paper summarizes clinical experience in treating acne based on the staged therapeutic principles of "eruption in warm diseases". It is considered that acne results from wind-heat retained in the lungs， invading the ying level and obstructing the blood collaterals， and is primarily a disorder involving both the wei and ying systems. In clinical practice， the treatment emphasizes the use of acrid-cool and sweet-cold methods. The core prescription is namely Yinqiaosan Qu Douchi Jia Xishengdi Danpi Daqingye Bei Xuanshen Fang （from Epidemic Warm Diseases ［《温病条辨》］）， and is adjusted according to the stage of disease. In the non-inflammatory stage， when the pathogen initially attacks the wei level， treatment focuses on acrid-cool herbs to release the exterior， with supplementary bitter-sweet ingredients such as Yejuhua （Chrysanthemum Indicum）. In the inflammatory stage， with pronounced heat toxin in the qi level affecting the ying and blood， and local stagnation of qi and blood， the approach is to clear heat and resolve toxin， using blood-cooling and stasis-resolving herbs early to prevent progression. Herbs such as Pugongying （Taraxacum Mongolicum）， Zihuadiding （Viola Yedoensis）， Tiankuizi （Semiaquilegia Adoxoides）， Chonglou （Paris Polyphylla）， Machixian （Portulaca Oleracea）， Zaojiaoci （Gleditsia Sinensis）， Chuanshanjia （Manis Pentadactyla） may be added. In the post-inflammatory erythema stage， when yin of the ying level is depleted and internal deficiency-heat arises， sweet-cold herbs are recommended to nourish the stomach and generate fluids， with the possible addition of Yiwei Decoction （益胃汤）.

This paper　explored the disease mechanism of autism spectrum disorders （ASD） from the perspectives of “vital activity” and “qi configuration”， and it is believed that “vital activity” represents the internal regulatory mechanisms of the human body， while “qi configuration” represents the ability of the body to communicate and adapt to the external environment. Abnormal genetic factors lead to the extinction of vital activity in children with ASD， resulting in increased susceptibility to ASD. Environmental instability leads to the solitary qi configuration in ASD， triggering and exacerbating the manifestations of ASD on the basis of genetic susceptibility. In addition， epigenetic mechanisms also play an important role in the pathogenesis of ASD. Imbalances in vital activity and disruptions in qi configuration result in failure in qi transformation of zang-fu organs， with abnormal symptoms manifested through the five orifices. It is proposed that the treatment of ASD should aim to achieve a harmonious interaction between “vital activity” and “qi configuration” to accelerate the recovery of affected children.

Postoperative delirium, one of the common complications in patients with hip fracture, has a high incidence and poor prognosis. As there have been no effective treatments for this complication, early prediction and intervention is the most effective method available to reduce its occurrence. This study reviews the types and characteristics of the patients who suffer from postoperative delirium after hip fracture, as well as the risk factors that have been currently found. The risk prediction models for postoperative delirium are also analyzed and compared in hip fracture patients from the perspectives of cohorts included, research design, model construction and validation methods, model performance, and clinical application. The limitations of existing models are analyzed to foresee the development trend of future delirium prediction models for hip fracture patients. This study aims to help clinical healthcare professionals to identify as soon as possible those who will face a high risk for postoperative delirium after hip fracture surgery and to work out algorithms for targeted prevention and management.

Proteins usually associate with other molecules physically to execute their functions. Identifying these interactions is important for the functional analysis of proteins. Previously, we reported the parallel analysis of translated ORFs (PLATO) to couple ribosome display of full-length ORFs with affinity enrichment of mRNA/protein/ribosome complexes for the "bait" molecules, followed by the deep sequencing analysis of mRNA. However, the sample processing, from extraction of precipitated mRNA to generation of DNA libraries, includes numerous steps, which is tedious and may cause the loss of materials. Barcoded PLATO (PLATO-BC), an improved platform was further developed to test its application for protein interaction discovery. In this report, we tested the antisera-antigen interaction using serum samples from patients with inclusion body myositis (IBM). Tripartite motif containing 21 (TRIM21) was identified as a potentially new IBM autoantigen. We also expanded the application of PLATO-BC to identify protein interactions for JQ1, single ubiquitin peptide, and NS5 protein of Zika virus. From PLATO-BC analyses, we identified new protein interactions for these "bait" molecules. We demonstrate that Ewing sarcoma breakpoint region 1 (EWSR1) binds to JQ1 and their interactions may interrupt the EWSR1 association with acetylated histone H4. RIO kinase 3 (RIOK3), a newly identified ubiquitin-binding protein, is preferentially associated with K63-ubiquitin chain. We also find that Zika NS5 protein interacts with two previously unreported host proteins, par-3 family cell polarity regulator (PARD3) and chromosome 19 open reading frame 53 (C19orf53), whose attenuated expression benefits the replication of Zika virus. These results further demonstrate that PLATO-BC is capable of identifying novel protein interactions for various types of "bait" molecules.

Objective To investigate the value of leukotriene B4(LTB4)and leukotriene E4(LTFA)in early diagnosis of renal involvement in children with Henoch Schonlein purpura(HSPN)and its influence on prognosis.Methods A total of 185 children with HSPN were enrolled in our hospital from January 2014 to October 2016.A total of 50 healthy children were selected as control group at the same period.The serum levels of LTB4 and LTFA in all subjects were detected,and their value in early diagnosis of HSPN and its influence on prognosis were analyzed.Results Compared with the control group,the serum levels of LTB4 and LT-FA in children with HSPN were significantly higher(P<0.05),the contents were 987.6 ng/L and 896.3 ng/L,respectively.The AUC of the combined detection of HSPN was 0.899 and the sensitivity was 0.810,which was better than that of LTB4 and LTB4 alone(P<0.05).The average follow-up was(28.4 ± 10.3)months,with grade A prognosis in 133 cases(71.9%),B grade in 47 ca-ses(25.4%),and C grade in 5 cases(2.7%).The rank sum test showed,the prognosis of children with LTB4<987.6 ng/L was better than that of children with LTB4≥987.6 ng/L,the prognosis of children with LTFA<896.3 ng/L was better than that of children with LTFA≥896.3 ng/L.Spearman analysis showed that the content of LTB4 and LTFA was negatively correlated with prognosis(Rs= -0.693 and -0.637,P<0.05).The higher contents of LTB4 and LTFA,the worse the prognosis.Conclusion Combined detection of LTB4 and LTFA has important clinical significance for early diagnosis and prognosis of HSPN.

The biotransformation, CYP reaction phenotyping, the impact of CYP inhibitors and enzyme kinetics of 3-cyanomethyl-4-methyl-DCK (CMDCK), a new anti-HIV preclinical candidate belonging to DCK analogs, were investigated in human intestinal microsomes and recombinant cytochrome P450 (CYP) enzymes. CMDCK (4 micromol L(-1)) was incubated with a panel of rCYP enzymes (CYP1A2, 2C9, 2C19, 2D6 and 3A4) in vitro. The remaining parent drug in incubates was quantitatively analyzed by a LC-MS method. CYP3A4 was identified as the principal CYP isoenzyme responsible for its metabolism in intestinal microsomes. The major metabolic pathway of CMDCK was oxidation and a number of oxidative metabolites were screened with LC-MS. The Km, Vmax, CLint and T1/2 of CMDCK obtained from human intestinal microsome were 45.6 micromol L(-1), 0.33 micromol L(-1) min(-1), 12.1 mL min(-1) kg(-1) and 25.7 min, respectively. Intestinal clearance of CMDCK was estimated from in vitro data to be 3.3 mL min(-1) kg(-1), and was almost equal to the intestinal blood flow rate (4.6 mL min(-1) kg(-1)). The selective CYP3A4 inhibitors, ketoconazole, troleandomycin and ritonavir demonstrated significant inhibitory effects on CMDCK intestinal metabolism, which suggested that co-administration of CMDCK with potent CYP3A inhibitors, such as ritonavir, might decrease its intestinal metabolic clearance and subsequently improve its bioavailability in body.

Studies have suggested that human cytomegalovirus-activated infection is closely associated with atherosclerosis. The levels of interleukin-8 increase significantly in human cyto-megalovirus infection-related atherosclerosis, inducing and aggravating inflammatory reaction through the chemokine receptors, and thus plays an important role in the process of atherosclerosis.
