ABSTRACT
Objective To investigate the genetic variation of Eurytrema pancreaticum isolated from goats in Huaihua City, Hunan Province. Methods The partial sequence of mitochondrial cytochrome I (pcox1) and ribosomal 18S rRNA genes were amplified using a PCR assay in E. pancreaticum isolates from goats in Huaihua City, Hunan Province, and the PCR amplification products were sequenced. Then, the gene sequences were subjected to genetic variation and phylogenetic analyses. Results The sequences of the pcox1 and 18S rRNA genes were 430 bp and 1 857 bp in length in 18 E. pancreaticum isolates from goats in Huaihua City, Hunan Province, and there were 14 and 35 variation sites in pcox1 and 18S rRNA gene sequences, with intra-species genetic variations of 0 to 1.4% and 0 to 0.8%, respectively. The sequences of pcox1 and 18S rRNA genes had 99.0% to 99.8% and 99.5% to 99.8% homologies with those from E. pancreaticum Chinese strain recorded in the GenBank database. Consistent phylogenetic analysis results were found based on pcox1 and 18S rRNA genes. The 18 E. pancreaticum isolates from goats in Huaihua City were clustered into a clade with the known E. pancreaticum isolates registered in GenBank, and the clade with these 18 E. pancreaticum isolates was close to the clades with Eurytrema species and far from the clades with other trematodes. Conclusions The E. pancreaticum isolates from goats have a low genetic variation in Huaihua City, Hunan Province. Mitochondrial pcox1 and ribosomal 18S rRNA genes may serve as molecular markers for the studies on the genetic variation in goat-derived E. pancreaticum.

ABSTRACT
Objective: To explore the material basis and anti-inflammatory mechanisms of Zukamu granules (ZKMG)based on the headspace-solid phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GCMS) technique and network pharmacology analyses. Methods: HS-SPME-GC-MS technique was used to extract and identify the volatile components of ZKMG. Then combined with the non-volatile components obtained by literature retrieval, we constructed the main chemical composition table. The bioactive components were screened based on the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and their targets were predicted by the Swiss Target Prediction database. Thereafter, the anti-inflammatory-related targets were screened based on the Thera- peutic Targets Datebase and DrugBank with”Anti-inflammatory”as keyword. Then, the STRING database to analyze protein-protein interaction(PPI)and the software of Cytoscape 3.6.1 was used to construct the component-target-antiinflammatory target network. Finally, enrichment of function and signaling pathways of the target genes was conducted by Gene Ontology(GO)database and the Database for Annotation, Visualization and Integrated Discovery(DAVID). Re- sults: Thirty bioactive components including thymol, kaempferol and quercetin in ZKMG were screened out. Ninety-seven targets were predicted and AKR1B1, ALOX15, ALOX5, CYP1A2, EGFR, CHRM1, NOS3, PLA2G1B, PTGS2, BCHE were key anti-inflammatory targets. Sixty-eight pathways related to anti-inflammation were obtained by KEGG enrichment analysis, mainly including arachidonic acid metabolism, MAPK signaling pathway, inflammatory mediator regulation of TRP channels, IL-17 signaling pathway and NF-κB signaling pathway. Conclusion: This study focuses on the chemical constituents of ZKMG and network pharmacology to predict the material basis and pharmacological mecha- nism of their anti-inflammatory effect, which lays a good foundation for the verification of the later biological experiments and provides certain reference basis for the research on the anti-inflammation mechanism of other compound preparations.
ABSTRACT
A 61-year-old woman was referred to our department with a 11-year-erythra. In the anterior tibia of both lower extremities, we could see large dark red infiltrating erythema, waxy luster, clear boundary, slight central atrophy, depression and capillary dilatation. He was diagnosed with "dermatitis contusiformis" in local hospitals, but the treatment of traditional Chinese medicine and external drugs was not effective. She had normal laboratory findings for blood routine test, biochemical indexes, C reactive protein(CRP) and erythrocyte sedimentation rate(ESR)．Furthermore, autoimmune antibodies were all negative. The skin pathology showed degeneration and necrosis of collagen fibers, chronic granulomatous inflammation in the dermis, and there were more acute and chronic inflammatory cell infiltration around the small vessels and in the wall of the tube. We eventually diagnosed it as necrobiosis lipoidica (NL) according to the history, erythra morphology and skin pathology. After treatment of low dose hormone and thalidomide for 1 year, the color and range of skin lesions gradually alleviated. NL was a rare chronic granulomatous inflammatory disease. There appeared to be a predominance in females. The incidence of NL was higher in patients with diabetes mellitus, although this asscoiation was currently questioned. NL might also be connected with autoimmune diseases, such as rheumatoid arthritis, sarcoidosis, ulcerative colitis and Crohn's disease. The pathological changes of the tissue were mainly in the dermis, including necrotic type, granulomatous type or mixed type. NL typically presented on the pretibial surface of lower extremities. Less typical locations included the face, scalp, vulva and upper limbs. Leisions usually began with small papules and nodules that gradually infiltrated into brownyellow patches and developed central wax-like atrophy. The diagnosis is often based on clinical examination and skin biopsy. NL is rare and easy to be misdiagnosed. For rheumatologists, we should carefully compare with the nodular erythema, the microscopic polyangitis and allergic purpura. It is significant for differential diagnosis to perform skin biopsy. Lacking of randomized controlled trials, no specific treatment has proven to be the gold standard. First-line therapy mainly consists of intralesional and systemic corticosteriods. Additionally, other reported treatment options include immunomodulator, biological agent, antiplatelet aggregation drug and plateletrich plasma. These patients need long term follow up continuously for progression of the disease, ulcerations, and possibility of malignant tranformation.

BACKGROUND: Bone marrow mesenchymal stem cells improve neurological functional recovery from cerebral infarction, but they are a rare population in the bone marrow with difficulty in cell separation and purification. OBJECTIVE: To investigate the neuroprotective effects and the potential mechanisms of human placenta-derived mesenchymal stem cell transplantation for cerebral infarction in rats. METHODS: Totally 120 rats subjected to middle cerebral artery occlusion were randomized into treatment group and control (n=60 per group). The rats were intravenously treated with human placenta-derived mesenchymal stem cells in the treatment group or the phosphate buffer saline in the control group. Then, a modified neurological severity score was assessed at 1, 3, 7, 14 days post transplantation, and measurement of infarct volume in the ischemic brain was performed using 2,3,5-triphenyltetrazolium chloride staining at 14 days post transplantation. The anti-human specific immunostain for mitochondria in the ischemic brain was performed and the mitochondria-positive cells were counted; TUNEL immunostaining was performed and TUNEL positive cells were counted. ELISA assays for brain-derived neurotrophic factor (BDNF), vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) were also performed in the ischemic brain. RESULTS AND CONCLUSION: At 1, 3, 7 and 14 days after treatment, the modified neurological severity score in the treatment group was significantly lower than that in the control group (P < 0.05). At 14 days after treatment, the infarct volume in the treatment group was significantly lower than that in the control group (P < 0.05), only few mitochondria-positive cells were present in the ischemic brain, and the number of TUNEL positive cells in the treatment group was significantly less than that in the control group (P < 0.05). At 3 and 14 days after treatment, BDNF expression levels in the treatment group were significantly higher than those in the control group (P < 0.05). At 7 and 14 days after treatment, VEGF expression levels in the treatment group were significantly higher than those in the control (P < 0.05). At 7 days after treatment, HGF expression level in the treatment group was significantly higher than that in the control group (P < 0.05). To conclude, intravenous administration of human placenta-derived mesenchymal stem cells can promote neuroprotective effects against cerebral infarction. These effects may be related to the increase of BDNF, VEGF and HGF expression and the decrease of apoptosis in the ischemic brain.

Objective: To study the various processes involved in transcellular transport (TT) of huperzine A alone or in combination with ginkgolide B in Caco-2 and Madin-Darby canine renal (MDCK) cell monolayer. Methods: The transepithelial passage was assayed in the apical-to-basolateral (AP to BL) direction and opposite direction (BL to AP) in both cell lines. The determination of huperzine A and ginkgolide B were performed by high performance liquid chromatography (HPLC). The passage rates of huperzine A and ginkgolide B were calculated. Bi-directional TT (absorption and secretion) were taken in huperzine A and ginkgolide B in Caco-2 and MDCK cell monolayer. Results: TT absorption and secretion kinetics of huperzine A and ginkgolide B across two cells existed at the same time. The passage rates of huperzine A were increased significantly with adding different concentrations of ginkgolide B. Conclusions: The compound preparations of HA in combination with GB for dementia caused by cerebral ischemic have synergistic effects on the pharmacodynamics, and improve the bioavailability through BBB.
