Acute intermittent visible fluorescent light was used as an experimental light source (18175?300lux, 1 hour dark: 1 hour light, 3 cycles). After light exposure, the myeloperoxidase activity (MDA) levels increased in rat retina, and the retinal structure and blood-retinal barrier were damaged. When 2 doses of anisodaminum (10 mg/Kg) were given 12 hours and just before light exposure, MDA levels lowered and the retinal structure was protected.

Objective To assess the safety and feasibility of minimally invasive percutaneous nephrolithotomy(mPCNL) in the treatment of solitary kidney calculi.Method Thirty-eight patients with solitary kidney calculi,treated with mPCNL from Jan 1998 to May 2004,were retrospectively investigated.Results Of 38 cases,there was 6 cases with pyonephrosis and 32 cases with the treatment of one stage percutaneous nephrolithotomy.With the treatment of 1 to 3 tract was used for calculus removed in all cases,a total of 86% stone-free rate was achieved.Only one case with pyonephrosis suffered from postoperative infection shock while one stage minimally invasive percutaneous nephrolithotomy was performed.Another one patient with diabetes suffered from postoperative ketoacidosis and no major complications were noted in other patients.Conclusion Minimally invasive percutaneous nephrolithotomy is safe and effective in the treatment of solitary kidney calculi.

The injectable calcium phosphate material is present to solve the clinical bone defects of bone tissue and the potential to undermine the ideal substitute. But the properties and biological evaluation are still to be improved. Therefore,the material of the academic community and the academic orthopedic bone cement was modified for a variety of studies,and the addition of strontium bone cement significantly improved the performance. The article indicated strontium-mixed calcium phosphate bone cement was characterizing by the compressive strength,the degradability,the hardening time,the solubility,the injection and the anti-water-solubility,suggesting the clinical practice of the strontium-mixed calcium phosphate bone cement. Prospectively,the strontium-mixed calcium phosphate bone cement may take in the bone tissue repair domain as a artificial bone substitution material.

Objective To establish an evaluation index system for access to ophthalmic surgery so as to standardize the access. Method Collect 14 ophthalmologists' recommendations on access criteria for ophthalmic surgery in two rounds of questionnaire survey by Delphi method. Results The return rate of rounds of consultation questionnaire was 93.33%, and the average expert authority coefficient was 0.78.Nine ophthalmic surgery access indicators were established. The coordination of expert coefficient was 0.521 after two consultation. It had significant difference ( P＜0.01 ). Conclusion The ophthalmic surgery access indicator system is highly credible and allows quantitative assessment of ophthalmic surgery from various aspects. It is more demanding for ophthalmologist, and gets more involvement of patients in the evaluation of ophthalmic surgery access. It could contribute to scientific and rational decision-making on access for ophthalmic surgery.

Objective To investigate,the significance of serum high-sensitivity C-reactive protein (hs-CRP) concentration in subjects with various glucose tolerance and study the role of hs-CRP in patients of impaired glucose tolerance (IGT) and diabetes mellitus.Method All subjects in the study underwent oral glucose tolerance test (OGTT).Determination of serum hs-CRP levels in normal glucose tolerance(NGT),IGT and type 2 diabetes mellitus (T2DM) patients were made by immunologic projective turbidimetry method.Results The levels of serum hs-CRP were (1.57 + 0.46) mg/L in NGT patients,(2.84 ±0.48) mg/L in IGT patients,and(4.18± 0.76) mg/L in T2DM patients.The levels of serum hs-CRP were positively correlated with body mass index,systolic blood pressure,diastolic blood pressure,fasting plasma glucose,OGTr 2 hPG,triglyceride,and total cholesterol.ConclusionsInflammation has already existed not only in T2DM patients but also in subjects with IGT.Inflammation might participate in the oeeurrance and development of T2DM.hs-CRP as an inflammator factor can be used to predict and monitor T2DM.

The advanced brain imaging technology and events related potentials, besides the traditional neuropsychological check method, had been much more applicated and studied in the diagnostic research of Chinese aphasia at present, and in the future the check methods of Chinese aphasia showed diversification, systematic and standardized development. A large number of clinical reshearches tended to comprehensive treatment as the main approach for Chinese aphasia in a conclusion.

Objective To apply joint fixation with breast bracket and body phantom to breast cancer radiotherapy after breast-conserving operation.Methods Totally 36 patients after breast-conserving operation underwent joint fixation with breast bracket and body phantom, whose cone beam computed tomography (CBCT) images were obtained with on board imager (OBI) before radiotherapy. The errors between the CBCT images and planning CT images were acquired by matching.Results The setup errors in the directions of left-right (X), head-foot (Y) and belly-back (Z) were (2.6±0.783), (3.0± 1.027) and (1.6 ±0.872)mm respectively, and the percentages that the setup errors were more than 5 mm were 16.5%, 20.7% and 9.1% respectively.Conclusion Joint fixation with breast bracket and body phantom may decrease the setup error in radiotherapy after breast-conserving operation, especially in the belly-back direction, and thus has high clinical values.

Objective To investigate the clinical efficacy and its security on different kinds of atomization with mucosolvan and chymotrypsin in treating neonatal pneumonia.Methods Seventy-eight neonates who were diagnosed as neonatal pneumonia were divided into treatment group (n =39) and control group (n =39) by random number table method from Jul 2011 to Aug 2013 in our hospital.The control group was treated with chymotrypsin atomization,and the treatment group was treated with compression atomizing to inhale mucosolvan.The treatment effects of two groups were compared.Results Compared with the control group after treatment for 24 h,48 h,72 h,the treatment group had more significant increasing in PaO2,more decreasing in PaCO2 and more significant improvement in oxygenation index.There were statistical significances between the two groups(P ＜ 0.01).The treatment group spent shorter time in remission of symptoms,disappear of signs and hospital stay than that of the control group(P ＜ 0.05).In the treatment group,25 cases were markedly improved,9 cases were effective,5 cases were invalid.The effective rate was 87.2％.In the control group,14 cases were markedly effective,6 cases were effective,19 cases were invalid.The effective rate was 51.3％.The effective rate was significant difference between the two groups (P ＜ 0.01).The adverse drug reactions were not found in the process of treatment for two groups.Conclusion Mucosolvan atomizing inhalation has a better treatment effect than chymotrypsin.It can shorten the course of treatment,and is worth promoting the application.

A 1.8 kb HinfI fragment carrying the chitinase gene(chiA) from Serratia marcescens was isolated from the plasmid pLCHIA and was inserted into the SmaI site downstream of the strong Ptac promoter in the expression vector pKK223-3,yielding the plasmid pKChiA.The 2.1 kb PtacChiA fusion fragment was excised by BamHI from the plasmid pKChiA and was inserted into the single BamHI site present within the plasmid pMC71A,thus generating the plasmid pMChiA.High levels of chitinase were produced by the E.coli strains HB101 and JM105 carrying the plasmid pKChiA or the plasmid pMChiA,with the amount of production were higher 1～3 fold than that produced by the strains carrying the plasmid pLCHIA.
