Inflammation is a common ocular surface disease.Glucocorticoid drugs are effective on the ocular surface inflammation,but their long-term and massive application is prone to serious side effects.Nonsteroidal antiinflammatory drugs (NSAIDs) have anti-inflammatory,anti-allergic,analgesic effects.The topical application of NSAIDs for the prevention and treatment of ocular inflammatory disease is much safer than that of glucocorticoid.Therefore,NSAIDs have more and more concerns in the treatment of ocular surface inflammation in recent years.Although NSAID has good anti-inflammatory effectiveness and less adverse effects,it should be correctly administered.During the treatment process of inflammatory ocular surface diseases,the combination of NSAIDs with glucocorticoid drug can strengthen the curative effect and reduce the adverse reactions.

Objective To investigate the efficacy of steroid spray nose treated in child with chronic nasosi- nusitis.Methods 161 cases who were examined a patient of the 5～14 years old child of a chronicⅠtype nasosi- nusitis were divided into two groups,A group 92 cases,spray with the steroid spray nose+the complex treatment.B group 69 cases,only uses the complex treatment,a month of the course of treatment,two groups of all match with the nasal sinuses to douche.Results All cases were followed-up for at least 6 months.In A group,71 cases were cured,13 cases turned for the better,8 was invalid.Total efficient rate was 91.3 %.In 13 group,40 cases were cured, 13 cases turned for the better,16 was invalid.The efficient rate was 76.8 %.The A group obviously surpassed the B group(P

Objective To explore the effect of bone marrow stromal cells (BMSC) transferred by Nell-1 gene combined with biomaterial fibrin glue (FG) to enhance segmental bone defect healing in dog mandible. Methods Nell-1 gene vector was reconstructed in retroviral vector and then transfected BMSC. The protein of Nell-1 gene in transferred cells was determined by immunohistochemistry. Segmental defects were created surgically in the dog’s mandible. The defect was repaired with BMSC transfected by Nell-1 retroviral granules in presence of FG,untransfected BMSC in combination with FG,and FG alone. The control group was left untreated. The defect-repairing capability for each treatment were assessed by gross observation,radiography,and histology at 8th week and 16th week. Results Cells transfected by Nell-1 retroviral granules expressed abundant Nell-1 mRNA and protein in the cytoplasm. Positive results were not found in those cells that were not transferred. The use of BMSC transferred by Nell-1 retroviral granules combined with FG materials exhibited the strongest defect-repairing ability. Gross observation,radiographical and histomorphometric analyses revealed a significantly greater total area of bone formation,increased amount of the new bone in the defects than in those treated with the untransfected BMSC. Conclusion Nell-1 gene transfection may be used to promote the osteogenic ability of BMSC.

Objective To investigate the relationship between the expression of laminin and laminin-receptor in pulmonary carcinoma and cancer metastasis as well as prognosis.Methods Techniques of immune histochemistry were used.Results The higher the pathological grade of pulmonary carcinoma was, the higher the level of expression of laminin was. There were significant differences betweenⅠgrade group andⅡgrade group and Ⅲ grade group and Ⅳ grade group. The expression of laminin was also related to lymph node metastasis (P

Objective To analyze the clinical and imaging features of 2 siblings with leukoencephalopathy due to NADH dehydrogenase (ubiquinone)flavoprotein 2 (NDUFV2) gene mutation,in order to better understand and diagnose it earlier.Methods Clinical and follow-up data of the proband and his brother were collected.Clinical features including symptoms,signs and cranial magnetic resonance imaging (MRI) were analyzed,and 2 patients were followed up for a long time.Sanger sequencing,targeted next generation sequencing,and whole exome sequencing were performed to identify potential genetic variations in the 2 patients and their parents.Results (1) Clinical characteristics and follow-up:ages of onset were 4 months and 1 year respectively.Both of the patients presented rapid motor regression hyperinyotonia,positive pathological character.During the follow-up the condition became stable,motor function and cognition improved gradually after cocktail therapy.(2) Brain MRI of the 2 patients showed prominent abnormalities in deep cerebral white matter,presenting T1 hypointense,T2 and fluid attenuated inversion recovery (FLAIR) hyperintense in the periventricular area.FLAIR images revealed that the abnormal white matter was partially rarefied and cavitated.Diffusion weighted images (DWI) showed high signals along the periphery of the involved areas.The follow-up MRI showed the cavitation still existed and even expanded,and DWI showed regional linear or spotty high signals around the original lesions.(3) Novel mutations in NDUFV2 gene,c.467T>A and c.404G>C,were identified in proband and his brother.The former inherited from his father,while the latter inherited from his mother,which was the new mutation not reported in the international.Conclusions The clinical features of the brothers presented subacute leukoencephalopathy with relatively stable or improved outcome.This was distinctive from the phenotypic features reported in 12 cases with hypertrophic cardiomyopathy or Leigh syndrome.The finding expanded the phenotypic spectrum of NDUFV2 mutations.Pathogenic gene of these patients which is the basis of genetic counseling for this family was determined.

Background and purpose: Urokinase-type plasminogen activator receptor is related to invasion and metastasis of tumor. Inhibition of uPAR expression in tumor cells results in reducing its metastasis. This study was aimed to construct an expression vector with short hairpin RNA (shRNA) of uPAR, which could pave the way for RNAi-mediated tongue squamous cell carcinoma therapy. Methods: Genome sequences of uPAR gene were retrieved from Genhank and cDNA was designed to code expression of shRNA for uPAR gene. The cDNA was synthesized and inserted into the eukaryotic expression vector pWH1, and the recombinant pWH1-uPAR expression vector was identified by enzyme cutting method. Then, pWH1-uPAR expression vector was transfected into tongue squamous cell carcinoma Ts cells by Lipofectomine 2000. At last, the expression of uPAR in Ts cells transfected with pWH1-uPAR expression vector was observed by RT-PCR, immunocytochemistry staining and Western blot. MTT assay was performed to measure the proliferation of Ts cell. Results: The uPAR shRNA eukaryotic expression vector was successfully constructed. Compared with Ts cells and Ts cells transfected with plasmid pWH1, the Ts cells transfected with pWHI-uPAR expression vector showed a lower mRNA and protein expression of uPAR. The inhibition rate of proliferation was 32.9% of Ts cells by transfected with pWHl- uPAR. Conclusion: The constructed uPAR shR.NA expression vector could inhibit the expression of uPAR in tongue squamous cell carcinoma, which may be helpful for further research on the function of uPAR and provide effective methods for therapy of tongue squamous cell carcinoma.
