As a leading cause of cancer deaths worldwide, lung cancer is a collection of diseases with diverse etiologies which can be broadly classified into small-cell lung cancer (SCLC) and non-small-cell lung cancer (NSCLC). Lung cancer is characterized by genomic and epigenomic alter-ations; however, mechanisms underlying lung tumorigenesis remain to be elucidated. Long non-coding RNAs (lncRNAs) are a group of non-coding RNAs that consist of P200 nucleotides but possess low or no protein-coding potential. Accumulating evidence indicates that abnormal expres-sion of lncRNAs is associated with tumorigenesis of various cancers, including lung cancer, through multiple biological mechanisms involving epigenetic, transcriptional, and post-transcriptional alter-ations. In this review, we highlight the expression and roles of lncRNAs in NSCLC and discuss their potential clinical applications as diagnostic or prognostic biomarkers, as well as therapeutic targets.

Objective To study the possibility of medication treatment in Alport′s syndrome(AS).Methods Two boys with AS,received cyclosporin A(CyA) in combination with angiotensin-converting enzyme inhibitor(ACEI) or only ACEI,which lasted 22 months and 20 months,respectively.Results After the treatments with the medication,there was obvious effectiveness in the 2 patients with relieved symptom and almost normal serum standard,especially the permanent and obvious recession of proteinuria.There was no side effects of medication during the treatment.Conclusion Patients with AS can be treated with CyA and ACEI,with symptomatic recession,as well as suspend the progression of pathology of kidney.

Objective To investigate the relationship between the clinical character and pathological variants as well as response to treatment of focal segmental glomerulosclerosis(FSGS) in children.Methods The clinical feature, laboratory data and histological variants of 48 children with idiopathic FSGS proven by renal biopsy were studied retrospectively. Among them,34 were boys;14 cases were girls. The age ranged from 1.75 to 16.0 years.Results Of 48 children with FSGS,nephrotic syndrome in 32(66.7%)was the predominant clinical manifestation. The pathological classification included FSGS not otherwise specified(NOS) in 29 cases(60.42%), perihilar variant in 14 cases(29.17%), tip variant 3 cases(6.25%), cellualr variant 2 cases(4.17%)and no collapsing variant. The different pathological variants had similar rate of segmental sclerosis glomeruli; perihilar variant had a higher global sclerosis glomeruli than FSGS NOS and other variants and there was a statistical significance(P 0.05).Vascular lesions were rarely seen in all kinds of histological variants of children.Conclusions Hypertension and renal insufficiency are less frequently seen in children FSGS, isolated hematuria as unique clinic presentation is common in FSGS. All pathological variants have tubular-interstitial lesions, but vascular lesions are rarely seen. Most FSGS children with nephrotic syndrome are sensitive to steroid at initial stage, and easy to develop frequent relapse gradually, immunosuppressive agent may be helpful to elevate remission rate.

OBJECTIVETo explore the effect of total flavonoids of Herba Epimedium (FHE) on BMP-2/RunX2/OSX signaling pathway in promoting osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs).

METHODSPassage 3 BMSCs were randomly divided into the control group, the experimental group, and the inhibitor group. BMSCs in the control group were cultured in 0.2% dimethyl sulfoxide + Osteogenuxic Supplement (OS) fluid + DMEM/F12 culture media. BMSCs in the experimental group were intervened by 20 microg/mL FHE. BMSCs in the inhibitor group were intervened by 20 microg/mL FHE and 1 microg/mL NOGGIN recombinant protein. At day 9 alkaline phosphatase (ALP) activity was measured. Calcium nodules were stained by alizarin red staining and the density was observed. The transcription expression of osteogenic differentiation-related proteins (type I collagen, osteocalcin, and osteopontin) and related factors of BMP-2/RunX2/OSX signaling pathway was assayed by RT-PCR.

RESULTSCompared with the control group, ALP activities were enhanced and the density of calcium nodules significantly increased; type I collagen, osteocalcin, and osteopontin expression levels were increased in the experimental group. The expression of osteogenesis-related transcription factor was also increased in the experimental group. Noggin recombinant protein inhibited FHE promoting BMSCs osteogenesis in the inhibitor group. Compared with the experimental group, ALP activity decreased (P < 0.05), the density of calcium nodules was lowered, expression levels of type I collagen, osteocalcin, osteopontin significantly decreased (P < 0.05) in the inhibitor group.

CONCLUSION20 microg/mL FHE promoted osteogenic differentiation process of BMSCs by BMP-2/RunX2/OSX signaling pathway.

OBJECTIVETo explore biomechanical properties and stress-strain of mucosa scars after cleft palate surgery.

METHODSAfter the model of mucosa scars was made, the mucosa scars and normal mucosa were excised and examined immediately by tensionometry.

RESULTSThe mucosa scars after cleft palate surgery were compared with normal mucosa. The Poisson's ratio of mucosa scars and normal mucosa was 0.5 and 0.49, respectively, showing no significant difference between the two groups. The ultimate Young's modulus of mucosa scars was about 24.22 MPa, however, it declined to 3.32 Mpa in normal mucosa.

CONCLUSIONSThe mucosa scars after cleft palate surgery are biomechanically weaker than normal mucosa. It can be used for further research, such as maxillary orthognathic surgery, distraction osteogenesis, and orthodontic treatment.

Abstract: Fifteen novel ligustrazine-tetrahydroisoquinoline derivatives were designed and synthesized according to the association principle of pharmaceutical chemistry. The structures were identified by IR, NMR and ESI-MS. The inhibitory activities of platelet aggregation induced by ADP and AA have been measured by Bron method. Preliminary pharmacological results showed that compounds 7g, 7h and 7n had potent inhibitory activity against platelet aggregation induced by AA, and the compound 7o showed significant inhibitory activity against platelet aggregation induced by ADP.

As there is widely application in clinical diagnosis and treatment with complete blood count(CBC)and differential count(DC),the experts of clinical hematology laboratory in the word have paid highly attention to the review of CBC and DC.In this paper,we would like to have an introduction for the suggested criteria for action following automated CBC and WBC differential analysis obtained from The International Consensus Group for Hematology Review and Clinical and Laboratory Standards Institute (CLSI).
