Objective To investigate the clinical outcome of post-traumatic tibial osteomyelitis treated by induced membrane technique combined with the antibiotic cement-coated locking plate.Methods A restrospective case series analysis was made on 71 cases of post-traumatic tibial osteomyelitis treated by induced membrane technique from September 2014 to September 2014.There were 55 males and 16 females, aged 18-60 years(mean, 37.4 years).Mean length of bone defect following debridement was 4.5 cm(range, 4-11 cm).Antibiotic cement-coated locking plates were used to provide the stability of the bone defects after one-stage debridement.Bone grafting and exchanging the plates with ntramedullary nails were done during the second-stage surgery.Parameters were monitored dynamically after operation to evaluate infection recurrence and bone healing, including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), clinical features(sinus formation, redness and swelling, warmth and pain) and X-ray films of the involved limbs.Results All patients were followed up for 13-25 months (mean, 19.5 months).There was no sign of recurring infection and CRP and ESR were normal in all cases after the first stage surgery.However, four cases (6%) had recurrent infection with sinus exudates and their CRP and ESR were abnormal after the second stage surgery, and further treatments were carried out on these patients.Follow-up showed bony union in all patients within mean 5.5 months (range, 4-6 months).Conclusion Induced membrane technique with antibiotic cement-coated locking plates for treatment of post-traumatic tibial osteomyelitis can shorten bone healing time and decrease infection recurrent rate without obvious impact on osteogenic activity.

10-15 years were 7 cases(6.3%),they were randomly divided into treatment group and contol group.The treatment group with 60 patients were given INF-? and polyresistin,age 3 years,given IFN-? 200 000 U per day;and polyresistin 5 mg per time,3 times every day,the course of therapy were 5 days.The control group was given traditional Chinese medicine at the same time.Results After therapy,in treatment group,53 cases(88.3%) of children′s cooling time were lower than 5 days,47 cases(78.3%) of children′s rash subsided time were lower than 6 days,48 cases(75%) of children′s Catarrhal symptoms disappeared time were lower than 5 days,and the rate of complications′ occurrence were 15 cases(18.3%).In control group,28 cases(53.8%) of children′s cooling time were lower than 5 days,14 cases(26.9%) of children′s rash subsided time were lower than 6 days,28 cases(53.8%) of children′s Catarrhal symptoms disappeared time were lower than 5 days,and the rate of complications′ occurrence were 37 cases(71.5%),there were significant differences between both groups(Pa

The zinc chloride and cystine resistant strain of S.cerevisiae YZM-14(ZnCl2r,Cysr) was screened with the mutant processing of the protoplast of S.cerevisiae by combinative mutagens of ultraviolet and nitrite.The glutathione(GSH) production(84.72 mg/L),dry cell weight(7.63 g/L) and the intracellular GSH content(11.10 mg/g) of YZM-14 were 2.79,1.63 and 1.71 times compared with that of the initial strain.The biosynthetic process of GSH was divided into three phases according to the time course of the specific cell growth rate and GSH yielding coefficient.In the second phase,the metabolic flux of the pentose phosphate pathway and the GSH precursors biosynthetic pathway of the mutant strain increased by 8.1 mmol/(g?h),compared with that of the initial strain.Furthermore,the metabolic flux of the organic acids secretion of the mutant strain decreased.Through these mechanisms,the utilization efficiency of the carbon sources was enhanced and high production of GSH was obtained.

Objective:To investigate the heterogeneity of epitopes recognized by anti-GBM autoantibodies in sera from a large cohort of Chinese patients with anti-GBM disease and its clinical significance.Methods: The present study included 108 patients with anti-GBM disease who were diagnosed in our hospital, between Jan 1991 and May 2009, with complete clinical and renal pathological data. Sera or plasma exchange of the patients were used to incubate with cryostat section of normal human renal tissue for indirect immunofluorescence (IIF) assay. The cryostat sections of normal renal tissue were pre-treated by 6 mol/L urea to unmask cryptic epitopes, and untreated cryostat sections were used to detect natural exposed epitopes. The sera were diluted from 1:2 to 1:512 to determine titers of anti-GBM autoantibodies Patients with anti-GBM autoantibodies against cryptic or exposed epitopes were further stratified;their clinical and pathological associations were analyzed. Results: Sera from all the 108 patients could recognize cryptic epitopes on normal renal tissue ( urea treated section). IIF showed IgG linear staining along GBM. However, sera from 56/108 patients (group A) could also recognize exposed epitopes on normal renal tissue (untreated section) ; sera from the rest 52/108 patients (group B) could not recognize exposed epitopes. In urea treated condition, the average titer of anti-GBM autoantibodies from sera of patients in group A was significantly higher than that in group B (P＜0.01) , ANCA-positive patients in group A were significant less than that in group B (P＜0.01) . There was no significant difference between the two groups in regard to other clinical data (including serum creatinine) and renal histopathologic data. Conclusion: Anti-GBM autoantibodies from some patients with anti-GBM disease could recognize natural exposed epitopes, however, their anti-GBM titer for cryptic epitopes was higher than that of those recognizing cryptic epitopes only and the prevalence of serum ANCA was significantly less.

The purpose of this study is to prepare galactosyl modified lipid bilayer-coated mesoporous silica nanoparticles (GPEM) to enhance the antitumor efficacy against hepatocellular carcinoma cells. The irinotecan (CPT-11) loaded mesoporous silica nanoparticles (MSNs) was coated with the Gal-P123 modified functional lipid bilayer by thin-film dispersion method. Nanoparticles were characterized with particle size, zeta potential, morphology and drug release in vitro. Afterwards, the cell uptake, intracellular concentration of CPT-11, cell apoptosis rate and cytotoxicity were evaluated on human hepatocellular carcinoma cell line Huh-7. The results showed that MSNs were coated with intact lipid bilayers and the nanoparticles had clear core-shell structure. GPEM is stable with the mean particle size of (78.01 +/- 2.04) nm. The low leakage rate in normal physiological conditions in vitro is contributed to the protection of stable lipid bilayer, and the fast drug release in acid environment due to the destruction of the lipid bilayer. On the cell level, the vector could improve the intracellular CPT-11 concentration by 4 times because of the functional lipid bilayer. The high CPT-11 concentration led to the increasement of apoptosis rate by 48.6%, and the reduction of half maximal inhibitory concentration (IC50) values of CPT-11 by 2 times, indicating stronger cell cytotoxicity.
