This paper aimed to explore the mechanism of the split components of Phytolaccae Radix by means of network pharmaco-logy. Based on the theoretical hypothesis of the nature and taste of traditional Chinese medicine, the chemical components of the separated components of Phytolaccae Radix were selected by using Traditional Chinese Medicine Systems Pharmacology Database(TCMSP) and Traditional Chinese Medicines IntegratedDatabase(TCMID) databases in combination with related literatures. Relevant target analysis was carried out based on PubChem and SwissTargetPrediction databases. Targets corresponding to disease were excavated based on GeneCards for each split component, corresponding potential targets were obtained through mapping the target set of target compounds to disease targets. GO biological process analysis and KEGG pathway enrichment analysis were performed on the mapped targets with the help of DAVID database. Based on Cytoscape software and the corresponding efficacy, the network diagram of "medicinal material-split components-compound-target-pathway" was constructed to explore the mechanism of different efficacy of the separated components of Cytoscape. And the target purgation and diuretic mapping was used as the target of the traditional efficacy of smoothening secretion for the first time. The study explored esculentoside component, fatty oil component and phenolic acid component, a total of 30 target compounds and 301 corresponding targets, involving 44 potential targets for "anti-inflammatory", 50 potential targets for "immunoregulation", 52 potential targets for "smoothening secretion", 28 potential targets for "antibacterial activity", 28 potential targets for "antiviral effect", and 29 potential targets for "antitumor effect". Topological analysis revealed 14 key gene targets such as MAPK8, MAPK14, EGFR and PTGS2. A total of 684 GO entries and 235 KEGG pathways were obtained through bioinformatics enrichment analysis, mainly involving TNF signaling pathway, NF-kappaB signaling pathway and MAPK signaling pathway. This study revealed the multi-component, multi-target, and multi-channel action mechanism of the split components of Phytolaccae Radix, which provided certain basis for the next step to clarify the split components of Phytolaccae Radix through the method of system biology, and injected new content and significance into the study of properties and flavors theory.

Herpes simplex virus type 1 (HSV-1) is a ubiquitous and widespread human pathogen, which gives rise to a range of diseases, including cold sores, corneal blindness, and encephalitis. Currently, the use of nucleoside analogs, such as acyclovir and penciclovir, in treating HSV-1 infection often presents limitation due to their side effects and low efficacy for drug-resistance strains. Therefore, new anti-herpetic drugs and strategies should be urgently developed. Here, we reported that baicalein, a naturally derived compound widely used in Asian countries, strongly inhibited HSV-1 replication in several models. Baicalein was effective against the replication of both HSV-1/F and HSV-1/Blue (an acyclovir-resistant strain)

【Objective】To provide a rabbit model for dry eye using a dry environment induced by Controlled Drying System.【Methods】Twenty-four male New Zealand rabbits were used in the experiment. They were randomly divided into control group and dry group,each one with 12 rabbits. The dry group was randomly housed in Controlled Drying System(CDS)for 14 days. The relative humidity,airflow and temperature were kept at(22±4)%,3~4 m/s and(23~25)℃, respectively. The control group were fed in a normal environment where relative humidity,airflow and temperature were kept at 60%~70%,0.2 m/s and(23~25)℃. The Schirmer test,corneal fluorescein staining,conjunctival lissamine green staining were performed during the experimental process on days 0,3,7,and 14. On the last day,the rabbits were euthanized and the eye tissues were made into paraffin-cut sections. After staining,we evaluated the corneal epithelial thickness and goblet cell number in the conjunctiva using light microscopy. MUC5AC in the conjunctival epithelium was detected by immunofluorescence. The apoptosis level changes on the ocular surface were evaluated using Caspase- 3 by immunohistochemistry. 【Results】 Decreased tear production ,increased corneal fluorescein staining and increased conjunctival lissamine green staining were found on days 3,7,and 14 in the dry group compared with the control group(P < 0.001). Corneal epithelial thickness of control group and dry group were (58.0±7.2)μ m and(47.8±7.6)μ m ,which showed corneal epithelial thickness of dry group was decreased(P<0.05). Goblet cells in the conjunctiva of control group and dry group were 15 ± 4 and 10 ± 2,which showed goblet cells of dry group was decreased(P<0.01). The expression of MUC5AC(consistent with goblet cells deficiency) was also reduced. Caspase- 3 was highly expressed on the corneal epithelium in the dry group. IOD/field of control group and dry group were(17±2)% and(20±2)%(P<0.01).【Conclusions】 Dry environment can make rabbits have pathological changes of dry eye on ocular surface epithelium. This dry eye model of rabbit caused by Controlled Drying System would be an effective tool to study the pathogenesis of dry eye.

Next generation sequencing (NGS) has developed very rapidly in the last decade. Compared with Sanger sequencing, NGS has the advantages of high sensitivity and high throughput. Movement disorders are a common type of neurological disease. Although traditional linkage analysis has become a standard method to identify the pathogenic genes in diseases, it is getting difficult to find new pathogenic genes in rare Mendelian disorders, such as movement disorders, due to a lack of appropriate families with high penetrance or enough affected individuals. Thus, NGS is an ideal approach to identify the causal alleles for inherited disorders. NGS is used to identify genes in several diseases and new mutant sites in Mendelian movement disorders. This article reviewed the recent progress in NGS and the use of NGS in Mendelian movement disorders from genome sequencing and transcriptome sequencing. A perspective on how NGS could be employed in rare Mendelian disorders is also provided.

Liver cancer is a common malignant tumor in China and a major health concern. We aimed to estimate the liver cancer incidence and mortality in China in 2010 using liver cancer data from some Chinese cancer registries and provide reference for liver cancer prevention and treatment. We collected and evaluated the incidence and mortality data of liver cancer in 2010 from 145 cancer registries, which were included in the 2013 Chinese Cancer Registry Annual Report, calculated crude, standardized, and truncated incidences and mortalities, and estimated new liver cancer cases and deaths from liver cancer throughout China and in different regions in 2010 from Chinese practical population. The estimates of new liver cancer cases and deaths were 358,840 and 312,432, respectively, in China in 2010. The crude incidence, age-standardized rate by Chinese standard population (ASR China), and age-standardized rate by world standard population (ASR world) were 27.29/100,000, 21.35/100,000, and 20.87/100,000, respectively; the crude, ASR China, and ASR world mortalities were 23.76/100,000, 18.43/100,000, and 18.04/100,000, respectively. The incidence and mortality were the highest in western regions, higher in rural areas than in urban areas, and higher in males than in females. The age-specific incidence and mortality of liver cancer showed a rapid increase from age 30 and peaked at age 80-84 or 85+. Our results indicated that the 2010 incidence and mortality of liver cancer in China, especially in undeveloped rural areas and western regions, were among high levels worldwide. The strategy for liver cancer prevention and treatment should be strengthened.

BACKGROUND AND OBJECTIVEThe effectiveness rate of all-trans-retinoic acid (RA) is only about 30% in the clinical application of inducing thyroid carcinoma differentiation. In addition, there are severe toxic side effects, which limit its clinical application. Phase I-III clinical studies have been conducted on the combined application of two or more kinds of inductors in tumors. Nevertheless, the combination of RA with histone deacetylase inhibitors is rarely reported. This article studied the effects of differentiation for papillary thyroid carcinoma and follicular thyroid carcinoma cell lines induced by RA combined with trichostatin A (TSA), enhancing the effect of induction, while reducing the toxic side effects of a single drug, to provide a theoretical basis for preclinical trials.
METHODSAfter incubation with RA combined with TSA, K1 and FTC-133 were grouped into Group 1 (RA 10(-4) mol/L plus TSA 1.65 x 10(-7) mol/L), Group 2 (RA 1 x 10(-4) mol/L plus TSA 3.31 x 10(-7) mol/L), Group 3 (RA 10(-5) mol/L plus TSA 1.65 x 10(-7) mol/L), Group 4 (RA 1 x10(-5) mol/L plus TSA 3.31 x 10(-7) mol/L) by four varied concentrations and three time points (12 h, 24 h, and 48 h). The cell proliferation, conformation, toxic effect, and induced differentiation on K1 and FTC-133 cell lines were studied microscopically with hematoxylin-eosin (HE) to observe cell quantity and morphology, methyl-thiazolyl-tetrazolium (MTT) to calculate cell survival rates, and electrochemiluminescence analysis measuring in vitro thyroglobulin (Tg) levels.
RESULTSThe research showed that K1 and FTC-133 cells had cell spacing increases, with an outer edge of smooth, nuclear chromatin condensation after RA combined TSA. Survival rate were assessed by an analysis of variance (ANOVA) by concentration and time point, F values of K1 and FTC-133 were 23.52 and 170.14, and 57.09 and 224.35, respectively. There were significant differences for both cells (P < 0.01). The SNK analysis indicated that survival rates were in the order of Group 2 < Group 1 < Group 4 < Group 3. Tg was also assessed by ANOVA, F values of K1 were 69.63 and 101.07, and F values of FTC-133 were 79.77 and 81.72 (P < 0.01). Group 1 was compared with Group 3 of K1 and FTC-133 by the least significant difference (LSD) method, and there was no statistical difference between the two group (P = 0.06, 0.2, respectively; P > 0.05), yet a significant difference was seen between the other Groups.
CONCLUSIONSLower concentrations of RA combined with lower concentrations of TSA have both inhibited cell proliferation, decreased toxicity of the drugs, and increased the effect of K1 and FTC-133 cell differentiation. The mechanism of action may be that TSA has pretranscription DNA regulation and that RA has posttranscriptional signal regulation to enhance the effects of inhibited proliferation and differentiation of cells by transcription systems.
