Objective To evaluate the therapeutic effects of aminoguanidine(AG) on cerebral ischemia-reperfusion damage in rats. Methods The intravascular thread models with 2 h of occlusion and 22 h of reperfusion were made in the rats.The brain infarction size and the degree of blood brain barrier(BBB) disruption in the ischemic regions were evaluated by staining with 2,3,5-triphenyl tetrazolium chloride and observing with Evans blue fluorescence microscope.HE staining was utilized for observing neutrophil infiltration. Results The brain infarction(volume,) the area of BBB disruption and the degree of neutrophil infiltration were dramatically decreased in the treatment group as compared to the control group(P

Abstract: Objective To investigate the distribution and drug resistance of pathogenic bacteria separated from ascites of patients in Children’s Hospital Affiliated to Zhengzhou University from 2015 to 2021, and to provide a basis for rational clinical antimicrobial agents. Methods Bacterial culture, bacterial identification and drug sensitivity analysis were performed on 1 058 non-duplicate ascites culture specimens from January 2015 to December 2021. The clinica1 and microbiologica1 data were ana1yzed by WHONET 5.6 and SAS 9.4 Results Of the 1 058 specimens, 586 (55.39%) were positive for pathogenic bacteria, with a total of 781 strains isolated. There was no significant trend of increase or decrease in the positivity rate over different years. Male children (63.99%) were more prevalent than female children. Appendicitis (59.22%) was the most common disease and Escherichia coli was the most common causative bacteria. Among neonates (≤28 d), the bacteria with the highest detection rate were Klebsiella pneumoniae (23.50%) and Enterococcus faecium (23.50%), while among children (>28 d), the highest detection rate was Escherichia coli (35.98%). Gram-negative bacteria accounted for 64.79% of the 781 strains, mainly Escherichia coli (38.28%), Klebsiella pneumoniae (8.58%), and Pseudomonas aeruginosa (5.89%); Gram-positive bacteria accounted for 29.45%, mainly Enterococcus faecium (8.58%), Streptococcus constellatus (2.69%), and Enterococcus avium (2.43%); fungi accounted for 1.66% and anaerobic bacteria accounted for 4.10%. The resistance rates of Escherichia coli to cefoperazone/sulbactam, piperacillin/tazobactam, imipenem and meropenem were 6.02%, 4.35%, 4.35%, and 3.68%, respectively. The resistance rates of Klebsiella pneumoniae to these drugs were 59.70%, 59.70%, 50.75% and 53.73% respectively. Linezolid-resistant strains of Enterococcus faecium were found. Conclusion Appendicitis is the most common abdominal infection in children, and the distribution of ascites pathogens varies with ages and diseases. The pathogenic bacteria are mainly Gram-negative bacteria, and the drug resistance of Klebsiella pneumoniae was more serious. It is particularly important to use antibiotics correctly and rationally to reduce the emergence of drug resistant bacteria.

With the help of ROSE, changing the ways, methods and modalities of interventional pulmonary diagnostic technology to obtain the target lesions is the core of this system. In this statement, the most commonly used standard operating techniques in The System of Diagnostic Interventional Pulmonology Based on Rapid on-site Evaluation are described in detail, including double-hinge curette operating technique, transbronchial lung biopsy (TBLB) technique, and transbronchial brushing technique.

AIM:To evaluate the feasibility and advantages of two-port 27-gauge pars plana vitrectomy for treatment of recurrent retinal detachment in silicone oil dwelling eyes.METHODS:A retrospective study.Two-port 27-gauge pars plana vitrectomy was performed in 7 eyes with recurrent retinal detachment without remove of silicone oil.Proliferative membrane peeling, endolaser treatment, and drainage of subretinal fluid were performed.Scleral bulking was performed if necessary.RESULTS:Sucessful retina re-attachment was accomplishied in all eyes.No visually significant intraoperative complication occurred.All eyes expericend quick recoveray of visual acuity and mild postoperative irritation.One eye developed a recurrent inferior retinal detchment in 20d after the surgery using non-remove technique, and recovered after conventional silicone oil removal and retinal reattachment surgery.CONCLUSION:Two-port 27-gauge pars plana vitrectomy is an efficacious (and potentially cost-efficient) method to treat early stage recurrent retinal detachment in silicone oil dwelling eyes.

Objective To explore the feasibility of constructing tissue engineered porcine corneal stroma with skin fibroblasts in vivo.Methods Skin fibroblasts were isolated from embryonic porcine,cultured and expanded in vitro.Cells were labeled with green fluorescence protein(GFP) gene by retro-viral infection.Cells at passage 3 were seeded on polyglycolic acid(PGA) non-woven fibers to form a cell-scaffold complex.The complexes were then implanted into porcines' corneal stroma after culturing in vitro for 1 week.Engineered stroma was observed continuously and harvested after 8 weeks for gross and histological evaluation.PGA with corneal stromal cells was served as control. Results The engineered tissue in the stroma gradually became transparent over a period of 8 weeks,showing no difference with the control group.Histologically,the engineered stromal lamellar was relatively regular and similar to the control.The implanted cells were confirmed by GFP expression under fluorescent microscope.By transmission electron microscopy examination, no significant difference in the diameter of collagen fiber was observed between the engineered stroma and normal stroma. Conclusion Tissue engineered corneal stroma may be formed with skin fibroblasts in porcine corneal microenvironment.

Objective To compare the Immunoreactivity of various HEV Antigen with Anti-HEV IgM. Methods Solid-phase enzyme immunoassay( EIA ) was developed for detecting anti-HEV IgM by using synthetic peptides E30, E42, E33, and recombinant antigen from HEV ORF-2. Results Of 60 anti-HEV positive sera by using E30, E42, E33 and recombinant antigen as coating antigen, Anti-HEV IgM positive rates were 76.7%, 26.6%, 18.3% and 66.7% respectively. In Acute-phase and convalescence-phase sera of the patients with Hepatitis E, Anti-HEV IgM positive rate was 90% and 3.3% respectively. Conclusions The HEV E30-based EIA will be very useful in the early diagnosis of Hepatitis E.

Abstract?AlM:To investigate the choice of different treatments for malignant glaucoma.? METHODS: ln this retrospective case series, 21 malignant glaucoma patients ( 21 eyes ) admitted in Wuhan General Hospital of Guangzhou Military Command from May 2012 to May 2013 were analyzed. Sixteen eyes ( 76%) developed malignant glaucoma after filtration surgery, 3 eyes ( 14%) after EX - PRESS glaucoma filtration device, 2 eyes ( 10%) after glaucoma filtration Ahmed valve implantation. Main Outcome of corrected visual acuity, intraocular pressure ( lOP ) , anterior chamber depth and complications were detected.?RESULTS: lOP recovered by drug control in 13 eyes, anterior chamber depth. Four eyes were treated by vitreous water- bag aspiration combined with anterior chambers reconstructing. Two eyes were treated by cataract extraction and intraocular lens implantation. Two eyes were treated by posterior capsule excision combined with anterior vitrectomy. lOP before and after treatment was 29. 81±4. 98, 12. 71±3. 77mmHg, respectively (P=0. 00). Anterior chamber depth before and after treatment was 0.41± 0. 34, 2. 13 ± 0. 54mm, respectively (P = 0. 00). Corrected visual acuity before treatment was 0. 19 ± 0. 17, after treatment was 0. 20±0. 16 (P= 0. 36). Except for vitreous hemorrhage in 1 eye, there were no ocular or systemic adverse events observed in all patients.? CONCLUSlON: lt is good to diagnose malignant glaucoma in early period, and treated it step by step. For this can reduce lOP and restore anterior chamber.
