Objective To assess the effect of sodium hyaluromate (HA) on degenerative disorders of the knee joint (KJ). Methods A prospective randomized controlled clinical trial was conducted. The experimental group received injections in the compartments of the involved KJ with 1% HA 20mg, whereas the control group received prednisolone (PS) of 75mg once a week with five injections as one course. One week before and after the treatment , clinical symptoms, amount of interleukin-6 (IL-6) and total protein of synovial fluid were measured and compared. Results Both drugs could relieve the clinical symptoms of KJ degenerative disorders. In HA group, marked improvement rate was 52.78% and failure rate was 2.86%, whereas marked improvement rate was 39.29% and failure rate 17.86% in PS group. The declined levels of IL-6 in synovial fluid were notably greater in HA group than those in PS group. Conclusion Intra-articular injection of HA is effective and safe in treating KJ dgenerative disorders with mild adverse reactions.

Objective To investigate the consistent long-term clinical efficacy of the procedure for prolapsed hemorrhoids (PPH) treatment for hemorrhoids.Methods Data of 87 patients with third-and fourth-degree hemorrhoids treated by surgical procedure for prolapsed hemorrhoids were collected.In all cases,third-degree hemorrhoids in 65 cases,fourth-degree hemorrhoids in 22 cases,median followed up after PPH was (3.8 ± 0.5) years.The long-term efficacy and the occurrence of complications were followed up to assess the effect of surgical procedure for prolapsed hemorrhoids.Results In patients with third-degree hemorrhoids,bleeding recurred in 2 cases (3.1%) for again bleeding,for anal bulge in 4 cases (6.2%).In patients with fourth-degree hemorrhoids,prolapse recurred in 2 cases (9.1%) for bleeding in 5 cases (22.7%).anal bulge 3 patients (13.6%),defecation difficult in one case (4.5%),one-degree of fecal incontinence in 1 case (4.5%),no other complications found,such as anal pain,anal stenosis,foreign body discomfort and fecal urgency.The chi-square test for comparison analysis suggested that:third-degree hemorrhoids postoperative prolapse and bleeding recurrence rate was significantly lower than fourth-degree hemorrhoids.Conclusions Procedure for prolapsed hemorrhoids treatment for hemorrhoids is safe and feasible,has small trauma,little pain,and definite efficacy,fewer complications,shorter hospital stay,lower reoperation rate,etc.But the long-term efficacy for third-degree hemorrhoids is superior to the fourth-degree hemorrhoids.

Objective To verify the effects of different conc entrations of auecifemine on the function of osteoblast cell expression and oste ogenic ability in vitro . Methods Iliac spongy bone specimens were obtained from twel ve adult patients scheduled surgery. After the bone pieces were treated with col lagenase-trypsin, osteoblasts were obtained from cancellous bones. Then the ost eoblasts were purified and cultivated. They were cultured in medium with various concentrations(1?10 -11 , 1?10 -9 , 1?10 -7 , 1?10 -6 , 1 ?10 -5 , 5?10 -5 mol?L -1 ). The alkaline phosphatase (ALP) acti vity, osterocalcin and osteogenic ability were examined by biochemical assay and radioimmunologic assay (RIA), respectively. Results The co rrelation of auecifemine of different concentrations with ALP activity and osteo calcin secretion was positive. Auecifemine of lower concentrations (1?10 -11 mol?L -1 , 1?10 -9 mol?L -1 and 1?10 -7 mol?L -1 ) s howed the stimulating effect on osteogenic ability and but not higher concentrat ion. Conclusion Estrogen can increase osteoblast ALP activi ty, osteocalcin production, and osteogenic ability.

Objective To study the surgical treatment of the pilonidal disease.Methods The clinical data of 33 cases of the pilonidal disease were retrospectively analyzed from Jul 2007 to Feb 2014.18 cases were treated with Excision and Marsupialization,and 15 cases were treated with Rhomboid excision and Limberg flap.Results All 18 cases in the excision and marsupialization group,were cured by surgery.all 15 cases in the rhomboid excision and Limberg flap group were cured,five of these cases were delayed healing dehiscence or necrosis,all this cases were healed after dressing drainage.The average healing time of the Limberg flap group was shorter than that of the Marsupialization group[(19 ±7) d vs.(37 ± 12) d,t =6.556,P < 0.01].Postoperative recurrence of the Marsupialization group was 1 case,the recurrence rate was 5.6%,and there was no recurrence after Limberg flap transfer.The recurrence rate of the 2 groups was statistically insignificant (P > 0.05).Conclusion The excision and marsupialization and the rhomboid excision and Limberg flap are effective in the treatment of the pilonidal disease,and the Limberg flap transfer is recommended in complicated and recurrence cases.

OBJECTIVE: To analyze transforming growth factor-β1( TGF-β1)-induced differentially expressed genes( DEGs) in human embryonic lung fibroblast( IMR-90) using microarray,and to screen the key genes and signaling pathways related to trans-differentiation of fibroblast.METHODS: The gene chip GSE17518,attained from TGF-β1 stimulated IMR-90 cells,was downloaded from the Gene Expression Omnibus database.The DEGs were screened by GENE-E software.Then,the DEGs were imported into the DAVID online database for Gene Ontology( GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes( KEGG) pathway enrichment analysis.The proteinprotein interaction( PPI) network was constructed and the hub genes were screened using STRING database and Cytoscape software.RESULTS: A total of 394 DEGs related to TGF-β1 stimulation were identified,including 171 down-regulated genes and 223 up-regulated genes.The results of GO analysis showed that the DEGs were widely distributed in cytoplasm,cell membrane,extracellular matrix( ECM) and exosomes,regulating biological functions such as ECM organization,cell migration and adhesion,cell proliferation and apoptosis.The results of the KEGG pathway analysis indicated that most of DEGs were enriched in cell focal adhesion,ECM-receptor interaction and phosphoinositide 3 kinase-Protein kinase B( PI3K-Akt) signaling pathways.The PPI network screened 10 core genes,included nucleolar protein 2( NOP2),succinate dehydrogenase B,glutamyl-prolyl-tRNA synthetase( EPRS),FtsJ homolog 3( FTSJ3),prefoldin subunit 4,Ras-related C3 botulinum toxin substrate 2,signal recognition particle receptor subunit beta,succinate-Co A ligase GDPforming beta subunit,pumilio RNA binding family member 3( KIAA0020),and general vesicular transport factor p115.NOP2,EPRS,FTSJ3,KIAA0020 were mainly distributed in M1 module.The NOP2 is the core gene with the highest number of nodes in M1 module.CONCLUSION: A total of 10 core differential genes and 7 signaling pathways related to TGF-β1 stimulation were screened.Among them,focal adhesion,ECM-receptor interaction,PI3K-Akt and NOP2,EPRS,FTSJ3,KIAA0020 may provide new direction for research of mechanisms of abnormal activation of fibrotic diseases including silicosis in incidence and development of multiple lung fibrotic diseases.

【Objective】 To investigate the preparation quality and clinical application effect of pooled platelets with leukocytes reduced. 【Methods】 The quality and clinical effect of the buffy-coated method prepared pooled platelets leukocytes reduced (experimental group, n=40) and apheresis platelets leukocytes reduced (control group, n=40) were compared. 【Results】 The platelet volume (mL), platelet count (×1011), red blood cell contamination (×108) and residual white blood cell (×106) of the experimental group and control group were 278.90±7.92 vs 276.52±8.01, 2.66±0.09 vs 2.66±0.83, 0.54±0.42 vs 0.83±0.84, 0.29±0.54 vs 0.27±0.51, respectively, with no significant difference. The results of bacterial culture were negative, all met the requirements of relevant national standards. In addition, the CCI (×103, 24 h) and PPR (%) were 15.11±9.86 vs 14.61±12.55 and 54.23±18.70 vs 61.41±19.09 respectively, with no significant difference, indicating a certain degree of therapeutic effect. 【Conclusion】 The quality and clinical therapeutic effect of pooled platelets leukocytes reduced were consistent with that of apheresis platelets leukocytes reduced.
