Merely having complete sequences of genomes is not sufficient to elucidate biological function. Proteomics is complementary to genomics because it focuses on the large scared gene products, which are the active agents in cells. As almost all the drugs are directed against proteins, proteomics have been widely used in pharmacological research.Proteomics profiling in drug target identification, toxicological and drug resistances research was reviewed.

Objective:To study the wound healing effects of the extracts of Shengji Huayu Fang with different solvents and demon-strate their important role in wound healing for deep second degree burn wound. Methods:Sixty Sprague-Dawley rats were randomly di-vidied into six groups(ten rats in each group): the control group (saline), the positive control group (asiaticoside group), Shengji Huayu Fang group respectively with petroleum ether, chloroform, ethyl acetate and n-butanol as the extraction solvent. The extracts of Shengji Huayu Fang with different solvents were applied in the rats with deep second degree burn wound, and the wound healing was e-valuated by the healing rate judged by naked eyes and computer image analysis, DNA cell cycle analysis using a flow cytometry, patho-logical reports and the degree of re-epithelialization studied by the other methods. Results:The mean healing time of the chloroform ex-tracts group [(15. 67 ± 1. 12)d] was much shorter than that of the control group [(22. 87 ± 1. 01)d, P<0. 01]. The hydroxyproline content and the percentage of S-phase cells in wound tissue in the chloroform extracts group was obviously higher than those in the con-trol group (P<0. 01). Conclusion:The present study indicates that topical application of chloroform extracts of Shengji Huayu Fang is beneficial to burn wound healing, and the chloroform extracts of Shengji Huayu Fang is the main bioactive fraction.

Neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory demyelinating disease of the central nervous system, primarily affecting the optic nerve and spinal cord.In addition to aquaporin 4 antibody, more and more studies have shown that interleukins (IL) also play an important role in the progression of NMOSD.For example, among the most common CD4 + T cells, Th17 cells can destroy the blood-brain barrier to invade the central nervous system and then affect autoimmunity; Th2-mediated IL-4 and IL-10 regulate immune activities by activating macrophages; Tregs can suppress the immune response by restricting various immune cell functions.The levels of related IL in the cerebrospinal fluid and blood of NMOSD patients vary at different stages of the disease course.This article mainly reviews the role and a change characteristics of interleukins related to NMOSD, which helps us to understand its pathogenic mechanism in-depth, and discusses whether IL can be used as immunophysiological markers to diagnose NMOSD.

Objective:To review and analyze the prescriptions for Chinese herbal pieces in an integrative traditional Chinese and western medicine hospital to explore the trend and problems in clinical application for Chinese herbal medicines and provide reference for dispensing in pharmacy of traditional medicine and rational drug use. Methods: Totally 1200 prescriptions for Chinese herbal pieces in our hospital were surveyed from January to December in 2014. The irrational use was analyzed, and reasonable suggestions were provided for the clinical application. Results:The problems in the prescriptions for Chinese herbal pieces included uncompleted diagnosis,incompatible diagnosis and medication,nonstandard Chinese name,unclear footnote,irrational usage or dosage and incompati-bility. The prescriptions including above 15 varieties of Chinese herbal pieces in one accounted for 65. 70%, and those with average dose above 250 g accounted for 40. 25%. Conclusion:Regular inspection and quality supervision on the prescription for Chinese herb-al pieces should be strengthened to improve the quality of prescriptions and guarantee the safety and economy of the medication.

Objective To inquire into the location of the relevant gene mutations in the Chinese familial hypokalaemic periodic paralysis, and to specify the correlation between the genotype and the clinical features of this disease. Methods Target-exon PCR and DNA direct sequencing were used to research the mutations in the CACNA1S, SCN4A, and KCNE3 genes of 14 familial hypokalaemic periodic paralysis probands. If a positive member was found, the other members of his (her) family must be inspected with the sequencing method. Results The probands of 3 families showed the known correlating mutations of hypokalaemic periodic paralysis, which were R1239H mutations in the CACNA1S in 1 family and R672H mutations in the SCN4A in the other 2 families. In addition, the differences of the age of onset, the responsibility to the treatment with acetazolamide and penetrance were found between the CACNA1S R1239H and SCN4A R672H mutations. Conclusions SCN4A R672H and CACNA1S R1239H mutations exist in the Chinese familial hypokalaemic periodic paralysis. Differences of the clinical features exist, resulting from these 2 kinds of mutations.

Objective To observe the blood perfusion of optic nerve and macular areas and investigate its relationship with visual field defect in nonarteritic anterior ischemic optic neuropathy (NAION). Methods Twelve consecutive unilateral NAION patients (course of disease <3 months) and 12 healthy Chinese adults were enrolled in the study. The affected eyes and fellow eyes from 12 NAION patients were defined as group A and group B; 12 eyes from 12 healthy adults were defined as group C. Best corrected visual acuity (BCVA), intraocular pressure (IOP), indirect ophthalmoscope and computer optometry were performed on all of the three groups of patients. Visual field (VF) and optical coherence tomography (OCT) were performed on NAION patients. Logarithm of the minimum angle of resolution (logMAR) was used to calculate visual acuity. Compared to group B, logMAR BCVA, mean deviation (MD) and pattern standard deviation (PSD) in group A were significant decreased (t=3.278, -4.909, 4.130, P<0.05). There was no significant difference in spherical equivalent, IOP, peripapillary retinal nerve fibre layer (pRNFL) between group A and group B (t=0.000, 0.890, 1.215; P>0.05). OCT angiography (OCTA) was used to measure the flow area (FA) at optic disc, flow area at radial peripapillary capillaries (RCFA) and FA, non-perfusion area (NFA), parafoveal vessel density (PVD) and parafoveal vascular index (PVI) in macular area. Pearson correlations between the deficiency of optic blood flow and visual field were analyzed. Results The differences of FA at optic disc and peripapillary RCFA among 3 groups were significant (F=4.162, 3.357; P<0.050). Compared to group B (t=-5.822, -7.467; P<0.001) and C (t=9.435, 4.615, P<0.05), FA at optic disc and peripapillary RCFA in group A was significantly reduced. There is several NAION showed quadrantal FA decreased in optic nerve. However, there was no significant difference in optic disc FA and peripapillar RCFA between group B and C (F=0.004, 0.030; P>0.050). There was no differences of FA, NFA, PVD and PVI among 3 groups (F=0.488, 1.107, 0.493, 1.086, 1.098, 0.093, 1.093, 1.221; P>0.05). Positive correlation between optic disc FA, peripapillary RCFA and MD (r=0.542, 0.585;P<0.05) were observed. However, there was no significant correlation between optic disc FA, peripapillary RCFA and PSD (r=-0.404, -0.430; P>0.05), and negatively correlated to BCVA (r=-0.617, -0.596; P<0.05). PRNFL was negatively correlated to optic disc FA (r=-0.643, P<0.05), but not correlated to peripapillary RCFA (r=-0.377, P>0.05). Conclusions The optic disc blood flow reduced in affected eyes of unilateral NAION whose disease course was less than 3 months, while the macular perfusion was normal. There was a positive correlation between optic disc flow and visual field.
