ObjectiveTo investigate the effect of early electro-acupuncture treatment on prevention of post-operative adhesions.Methods40 rabbits were randomly divided into 5 groups: normal control group, model group 1, model group 2, early electro-acupuncture group and later electro-acupuncture group with 8 animals in each group. Muscle adhesion model was established by operation. The early electro-acupuncture group was received the treatment from the 11th to 20th day after the operation; later electro-acupuncture group was from the 21st to 30th day after the operation. The weight, gait and range of motion (ROM) of animals were observed and analyzed.ResultsThe standing, walking and ROM of animals of the early electro-acupuncture group improved; but only few gait indexes improved and ROM not changed in the later electro-acupuncture group.ConclusionThe early electro-acupuncture treatment can prevent the post-operative adhesion of muscles, but not having effect on formed adhesion.

Wide- angle viewing system as an important auxiliary device can clearly observe the whole fundus field of vision in vitreous surgery, which enable vitreoretinal surgery more efficient, safer and more effective. So it has very high application value in ophthalmologic operation. In this paper, we studied the development and application of wide - angle viewing system in vitreoretinal surgery in recent years, from which we summed up the advantage of non - contact wide - angle viewing system in clinical field, and pointed out the shortcomings. The ultimate goal is to make the non -contact wide - angle viewing system better applied in vitreous surgery.

AIM: To investigate the potential role of 14-3-3 tau in trophoblast cells on invasiveness. METHODS: 14-3-3 tau expression was detected in first-trimester villi, deciduas and human trophoblastic cell line (BeWo) by immunohistochemistry. Small interference RNA (siRNA) targeting 14-3-3 tau was transfected into BeWo cells. The effects of down-regulated 14-3-3 tau on invasion of human trophoblasts cell line BeWo were examined by matrigel invasion assay, and the transcription, translation of E-cadherin and snail were estimated by RT-PCR or Western blotting. U0126 was used to detect the extracellular-signal related kinase 1/2 (ERK1/2) function on down-regulation of 14-3-3 tau induced cell invasion. RESULTS: 14-3-3 tau was detected in the invasive trophoblastic cells in the first trimester villi and that invaded to the deciduas. BeWo cells also expressed 14-3-3 tau. Down-regulation of 14-3-3 tau increased the invasive cell-number of BeWo, as well as the expression of snail, and inhibited E-cadherin. U0126 inhibited the enhanced invasiveness in these cells induced by the down-regulation of 14-3-3 tau. CONCLUSION: 14-3-3 tau may regulate the invasiveness of human trophoblastic cells through ERK1/2 signaling pathway.

Objective To analyse a novel splice mutation in EXT1 gene of hereditary multiple osteochondroma, and study its pathogenic mechanism.Methods In April of 2013, the proband was hospitalized from the outpatient department with multiple joint deformity for more than 20 years, peripheral blood of the proband and his parents were collected and genomic DNA was extracted .Coding regions and adjacent intron sequences of EXT1/EXT2 genes in genomic DNA of the family members were amplified and sequenced.Bioinformatics was used to analyze the mutation from sequencing .cDNA from peripheral blood of the proband ,the mother and normal control was made respectively as a template for amplifying coding regions of EXT1 gene, and the product was T-A cloned and sequenced.The abnormal transcripts of each group were counted and analyzed using chi square test to study the pathogenic mechanism of the mutation .Results Sequencing results of family members revealed that there was a heterozygous deletion mutation ( c.1284 +2del) in the 5′splice site of intron 4 in EXT1 gene of the proband and his mother .Bioinformatics predicted that exon 4 of EXT1 gene was skipping or spliced aberrantly due to the mutation .T-A clone and sequencing results as well as the statistical analysis suggested that there was a significantly higher proportion of transcripts with skipping exon 4 in the proband and his mother compared with the normal control (P=0.000, P<0.01).Conclusions c.1284+2del in EXT1 gene is reported for the first time internationally , which results in a considerable number of abnormal transcripts with skipping exon 4 in EXT1 gene, thereby influences the normal transcription and translation of EXT1 gene.

Objective To observe the bioactivity of recombinant human scFv antibody against NH-lipopolysaccharide binding protein in vitro and in vivo. Methods KM mice, weighing 20-25 g, were burnt on the back to the third degree covering 20% total body surface area. The mice in only burn group were intraperitoneally injected with 1 ?g/g LPS and those in scFv-treated group with 1 ?g/g LPS and 0.5 ?g/g scFv after burn. The mice without any treatment served as controls. All mice were sacrificed in 1, 3, 6, 12, 24 h after all treatment and the whole blood, the tissues of liver, lung and kidney were collected. The serum concentration of TNF-?, IL-6 in burnt mice with endotoxemia was detected by ELISA and the pathological changes of liver, lung and kidney tissues were observed by light microscope. The inhibition of scFv antibody of different concentrations against NH-lipopolysaccharide binding protein on FITC-LPS binding with U937 cells was assayed by FCM. Results The histopathological changes of liver, lung and kidney in mice of scFv-treated group revealed that less inflammatory cell infiltration, less degenerated cells, weaker congestion in tissue as compared with control and only burnt mice. The serum concentration of TNF-? in only burnt mice increased significantly than that of the controls (P

Objective patients with pSS and 30 cases of healthv contrels.The streptavidin immunohistochemical staining was performed to detect the expression and distribution of MMP-9 and CD147 in labial salivary glands.Quantitative analysis was performed by image analysis software-image plus 5.0 at the site of positive expression of MMP-9 and CD147.The correlation between their expression and the infiltrating lymphocyte foci per 4 mm2 of labial gland was analyzed by SPSS software as well as the correlation between the expression of MMP-9 and CD 147 in the salivary glands of patients with pSS.Results MMP-9 was hiKhly expressed in labial salivary glands from 52 patients with pSS and 30 healthy controls,but the expression of MMP-9 in pSS was stronger compared with that of healthy controls(P<0.01).There was a significant positive correlation between lymphocyte foci score and up-regulated expression of MMP-9 in labial salivary glands from 52 patients with pSS(P<0.01).CD147 was highly expressed in labial salivary glands from 52 patients with pSS and 23 healthy controls，but over-expression of CD147 in PSS was more Drominent compared with that of controls(P<0.01).There was a significant positive correlation between lymphocyte foci score and up-regulated expression of CD147 in labial salivary glands from 52 patients with pSS(P<0.01).The expression of MMP-9 and CDl47 was detected in ductal and acinar epithelial cells,lymphocyte foci in pSS.There was linear correlation between the expression of MMP-9 and CDl47 in the salivary glands of patients with pSS(P<0.01).Conclusion The results of this study suggest that the abnormal expression of MMP-9 and CD 147 is involved in the pathogenesis of pSS and play a crucial role.The interaction of MMP-9 and CD147 may be one of theimportant mechanisms leading to labial salivary glands destruction found in pSS.

Objective To analyze the characteristics of hospitalized patients with systemic lupus erythematosus (SLE) in Ningxia Hui Autonomous Region,and to characterize the epidemiology of SLE.Methods The data of 184 patients admitted to Ningxia Medical College Hospital during January 2008 to December 2013 were retrospectively analyzed.The data analysis included the initial symptoms,system involvement and clinical situations.Chi-square test,t test,Mann-Whitney U test and Logistic analysis were used for statistical analysis.Results ① The ratio of male and female was 1∶9.8.The most common clinical symptoms was rash in 72 cases (39％),and followed by joint pain in 61 cases (33％),swelling in 28 cases (15％) and fatigue in 21 cases (11％).② Eighteen percent (33/184) patients were late-onset SLE patients.Compared with regular SLE patients,the interval was longer in late-onset SLE patients between clinical symptoms onset and the time when they saw the doctor.③ Blood and kidney were the most commonly affected organs.④ The highest diagnosis rate occurred in rheumatology department,the highest diagnosis rate occurred in the kidney department for patients with dropsy as starting symptom.Conclusion SLE primarily occurs in childbearing aged women.The reason of misdiagnosis of SLE is mainly due to the incorrect hospital selection for the first visit.Delayed diagnosis will lead to delay in the treatment.
