To investigate the curative effect of minimally invasive sclera buckling on single retinal detachment.METHODS:Totally, 100 cases of patients with retinal detachment ( 106 eyes ) enrolled in our hospital were randomly divided into observation group and control group, 53 eyes in each group. Patients in observation group were treated with minimally invasive sclera buckling, while patients in control group received traditional limbal conjunctival incision. After surgery, patients were all followed up for 6 ~18mo, during which the retinal recurrence situation, degree of vision enhancement and compliance occurrence rate was recorded. RESULTS: The retinal reattachment rate once of observation group (96. 22%) was significantly higher than that of control group (88. 68%), there was statistically significance (P<0. 05). The vision enhancement rate of observation group (84. 90%) was significantly higher than that of control group (71. 70%), there was statistically significance (P<0. 05). The compliance occurrence rate of observation group (11. 32%) was significantly lower than that of control group (32. 08%), there was statistically significance (P<0. 05).CONCLUSlON: The improved minimally invasive sclera buckling can significantly enhance the curative effect for retinal detachment, decrease the compliance occurrence rate, improve vision function, and is a scientific, practical and rigorous tool for retinal detachment treatment.

Objective To explore the influence of score sheet of colostomy on reduction of complication in non-hospitalized patients with colostomy stoma.Methods 186 patients with colostomy stoma were randomly divided into group A and group B.Group A used the score sheet of colostomy with nurses during hospitalization and after discharge.Group B were in routine treatment without using the score sheet of colostomy.The two groups were followed-up by phone or by visiting in the following 1,3,6 months after discharge.Results The complications between the two groups were evaluated.The risk of the complications was only 14.0% in group A,and the risk in group B was 36.6%.The results of self-satisfaction degree was significantly different between two groups.Conclusions The use of the score sheet of colostomy can significantly reduce the incidence of stoma complications and obviously improve the quality of life of the patients with colostomy.

This study is to investigate the inhibitory effect of kaempferol on inflammatory response of lipopolysaccharide(LPS)-stimulated HMC-1 mast cells. The cytotoxicity of kaempferol to HMC-1 mast cells were analyzed by using MTT assay and then the administration concentrations of kaempferol were established. Histamine, IL-6, IL-8, IL-1β and TNF-α were measured using ELISA assay in activated HMC-1 mast cells after incubation with various concentrations of kaempferol (10, 20 and 40 µmol.L-1). Western blot was used to test the protein expression of p-IKKβ, IκBα, p-IκBα and nucleus NF-κB of LPS-induced HMC-1 mast cells after incubation with different concentrations of kaempferol. The optimal concentrations of kaempferol were defined as the range from 5 µmol.L-1 to 40 µmol.L-1. Kaempferol significantly decreased the release of histamine, IL-6, IL-8, IL-1β and TNF-α of activated HMC-1 mast cells (P<0.01). After incubation with kaempferol, the protein expression of p-IKKβ, p-IKBa and nucleus NF-κB (p65) markedly reduced in LPS-stimulated HMC-1 mast cells (P<0.01). Taken together, we concluded that kaempferol markedly inhibit mast cell-mediated inflammatory response. At the same time, kaempferol can inhibit the activation of IKKβ, block the phosphorylation of IκBα, prevent NF-KB entering into the nucleus, and then decrease the release of inflammatory mediators.

Objective To explore the possible effect of Nogo-A receptor antagonist NEP1-40 on neurite outgrowth in neonatal rats with hypoxic-ischemic brain damage(HIBD).Methods Sixty-four healthy Wistar rats were randomly divided into 8 groups at 2 different time points(6 h,24 h):control group,HIBD group,NEP1-40 group and ganglioside group(GM-1 group).Rats of control group and HIBD group were injected with saline(0.25 mL/kg)by intraperitoneal injection,while rats of NEP1-40 group and GM-1 group were administrated with 10 mg/(kg?d) NEP1-40 and 20 mg/(kg?d) GM-1 on request in each group,respectively.Immunohistochemical staining was adopted to detect the Nogo-A-positive cells,and ultrastructural changes of neuron and axon were observed by transmission electron microscopy.SPSS 13.0 statistical software was used to run One-Way ANOVA tests on the data presented.Results The Nogo-A-positive cells at 2 time points in rats of HIBD group were significantly higher than those of control group(t=7.63,15.13 Pa0.05),while the Nogo-A-positive cells in GM-1 group at 24 h was lower than that of HIBD group(t=4.25 P

The present is aimed at identifying the activation of TRAFs in n asopharyngeal carcinoma (NPC) in vitro. The differential expression of TRAF2\,TRAF3 was not detected in RN A and protein level, whereas the expression of TRAF1 in HNE2-LMP1 cell lines wa s much more abundant than that in HNE2 cell lines, suggesting that TRAF1 may be an inducible molecule; More importantly, TRAF1, TRAF2 or TRAF3 were activated in the HNE2-LMP1 cells, whereas TRAF1, TRAF2 or TRAF3 were not activated in HNE2 cells as detected by the immunoprecipitation-Western blotting assay. These data provide an experimental basis for our study beginning from the signal transduca tion pathway for the eluccidation of the mechanism of LMP1 carcinogenesis in NP C.

Objective To investigate whether the protein kinase C inhibitor can promote the apopto- sis of multidrug resistance tumor cell lines which are induced by chemotherapy drugs.Methods Choose the KB/S(oral squamous cancer cell line)and KB/VCR(its multidrug resistant cell line)to compare the Adri- amycin-induced apoptosis with or without staurospolin(protein kinase C inhibitor).The apoptosis is stained with acridine orange,tested by flow cytometry,and approved by electron microscope.Results 36 hours after the treatment with 0.04 ?g/ml adriamycin,apoptotic cells of KB/S are 96.68%,and after 48 hours,the apop- totic cells of KB/VCR are 64.99%.When the concentration of adriamycin are augmented to 0.4?g/ml and 2.0?g/ml,the apoptotic cells of KB/VCR are 69.74% and 37.18% respectively.When treated with stau- rospolin together,the apoptotic cells of KB/VCR increased to 72.58%(?~2=4.5,P0.05)respectively.These results were testified by electron microscope and acridine orange-stain.Conclu- sion The resistance to apoptosis may be one of the mechanisms of multidrug resistance and the protein ki- nase C inhibitor may reverse this resistance by promoting the apoptosis of multidrug resistance tumor cells.

OBJECTIVE:
To observe the efficacy of intratympanic steroid injection as supplementary or initial treatment for sudden sensorineural hearing loss (SSNHL).
METHOD:
A total of 68 patients diagnosed with SSNHL were randomized into group A (45 cases including systemic steroid for 33 cases and systemic steroid + intratympanic steroid as supplementary treatment for 12 cases) and group B (23 cases, initial intratympanic steroid). Then observe the therapeutic effect in two groups.
RESULT:
The total effective rate was 55.6% in group A and 56.5% in group B. No statistical difference was detected between these two groups (P > 0.05). There was statistical difference after therapy of intratympanic steroid as supplementary treatment for 12 patients due to poor hearing improvement after systemic steroid in group A (P < 0.05).
CONCLUSION
Both systemic and intratympanic steroid injection for SSNHL are effective. The efficiency of intratympanic steroid injection as supplementary or initial treatment for SSNHL is similar to that of systemic steroid. The intratympanic steroid injection for SSNHL as initial protocol or as supplementary treatment when poor hearing improvement after systemic steroid is recommended.

Objective To investigate the benefits of long-term home noninvasive positive pressure ventilation(NIPPV) for patients with stable chronic obstructive pulmonary disease(COPD). Methods From 2006 to 2007,46 patients with chronic respiratory failure due to stable COPD receiving NIPPV in Croix Rousse Hospital were retrospectively analysed.The arterial blood gas analysis of before treatment,1,3,6,12,24 and 36 months after treatment were compared,and the lung function of before treatment,6,12,24 and 36 months after treatment were also compared. Results PaCO2 of 1,3,6,12,24 and 36 months after receiving NIPPV significantly decreased(P
