· AlM: To explore the correlation of center retinal thickness and axial length in non-proliferative diabetic retinopathy ( DR) .
· METHODS:A total of 80 cases ( 155 eyes ) of non-proliferative DR patients were divided into three groups according to the axial length, 22~24mm of 27 cases (51 eyes) were normal group, 24 ~26mm of 28 cases ( 55 eyes) were long axis group, >26mm of 25 cases ( 49 eyes) were super long axis group.The center retinal thickness and ocular axial length of three groups were measured and the correlation of center retinal thickness and axial length were analyzed.
· RESULTS:Among the inner ring and outer ring, the center retinal thickness of upper and lower, bitamporal and nasal side of super long axis group was thicker than that in normal group, with statistically significant difference ( P<0.05 ); Among the inner ring and outer ring, the center retinal thickness of upper and lower, bitamporal and nasal side of super long axis group was thicker than that in long axis group, with statistically significant difference ( P<0.05); The DR central macular of retinal thickness was no correlation of the axial length ( P >0.05 ), but retinal thickness get thinning with increased of axial length on the inner ring and outer ring area, showed a negative correlation ( rinner ring =-0.63, router ring=-0.67, P<0.05).
·CONCLUSlON:Center retinal thickness and ocular axial length in non -proliferative DR patients, and center retinal thickness of super long axis patients are thinning obviously.

Objective:To explore the clinical characteristics of patients with pituitary thyrotropin-secreting adenoma and evaluate the effect of preoperative short-acting octreotide treatment on hyperthyroidism.Methods:A retrospective analysis was performed in 40 patients with pituitary thyrotropin adenoma diagnosed in Beijing Tiantan Hospital from January 2008 to January 2018. The general data, laboratory examinations and imaging findings were reviewed and analyzed. The clinical effect of preoperative octreotide on hyperthyroidism was evaluated.Results:The age of onset year of the 40 patients (male: female = 24∶16) was (30.5±5.1) years. Among them, 35 patients (87.5%) were with macroadenoma. The most common symptoms were thyroid hypermetabolism syndrome, followed by headache, dizziness, visual field damage and hypogonadism. The thyroid function of 30 patients (75%) recovered to normal within 3-5 days after the octreotide treatment. The total effective rate of the octreotide was 90.0%. The level of free thyroxine (FT 4) before treatment in patients with more than 10 times of effective cumulative dose was significantly higher than that in patients with less than 10 doses. Conclusions:Thyroid hypermetabolism syndrome and pituitary occupying effect are the most common clinical manifestations of thyrotropin-secreting adenoma. Preoperative octreotide treatment can effectively control hyperthyroidism. The level of FT 4 is a crucial factor affecting the efficacy of octreotide.

ObjectiveTo explore the clinical presentation, diagnosis, treatment, and outcome of the Barth syndrome (BTHS).MethodsClinical data were collected and analyzed from 3 patients with conifrmed genetic diagnosis of BTHS from June 2013 to October 2014.ResultsAll of the 3 patients were males and two of them were twins. The main clinical manifes-tations of the 3 patients were cardiomyopathy and heart failure, accompanied by different degrees of trabeculations of the left ventricle. Two of them were diagnosed of left ventricular noncompaction (LVNC). All of the 3 patients presented with motor retardation, muscle weakness, growth delay and signiifcantly increased urinary excretion of 3-methylglutaconic acid (3-MGC). One patient was found to have neutropenia. All 3 patients hadTAZ gene mutations which included a novel missense mutation (c.527A>G, p.H176R) detected in the twins and a known nonsense mutation (c.367C>T, p.R123X) identiifed in the other patient. All of the mutations were inherited from their mothers. During the follow-up, the twins died at 7 months old and 7.5 months old respectively. The other patient was still alive.ConclusionBTHS is one of the causes of cardiomyopathy in children. In the male patients who presented with muscle weakness, neutropenia, and increased urinary excretion of 3-MGC, especially in those com-bined with LVNC, BTHS should be screened.

Objective To investigate the different effect among ropivacaine,bupivacaine,lidocaine on analgesia after harvesting grafts from the scalp in burn patients. Methods 84 patients who need harvesting grafts from the scalp after burn were divided in 4 groups random-ly(n=21). Patients in group C hypodermically injected with saline 200 mL were control,while patients in group R injected with 0. 05% ropi-vacaine 200 mL,group B with 0. 188% bupivacaine,and group L with 0. 1% lidocaine. Motor activity assessment scale( MAAS) and visual analogue scale(VAS) were made before anesthesia(T0) and 20 min,5 h,10 h after awake of patients. VAS were made focus on head and body in part. Vital signs were also monitored and recorded for assessment of security. Results All patients in 4 groups had passed the period of operation safely. Patients in group R have better VAS than other groups. Conclusion Low concentration ropivacaine hypodermically injec-tion of head is helpful to relieve the pain after harvesting grafts from the scalp.

RNA interference ( RNAi) is a process in which double-stranded RNA ( dsRNA) induces specific postranscriptional silencing of homologous transcripts. Systematic silencing of genes on a genome-wide scale using RNAi library targeting many thousands of genes provides a powerful research tool in functional genomics. RNAi libraries, which may be derived from plasmids cloning, virus packaging, PCR amplification, chemically synthesis or enzymatic digestion, have been successfully used to identify gene function, dissect signaling pathway and discover drug targets, etc. Promising progresses have been made in this field. The development, application and problems of RNAi library methodology and future prospects were reviewed.

There are many different opinions about the taxonomy of plant pathogenic coryneform bacteria since they were departed from genus of Corynebacteria. In recent years, they were classified into 5 genus, including Clav-ibacter, Curtobacterium, Arthrobacter, Rhodococcus and Rathayibacter. Some new points of view about their taxonomy have been published thereafter. The changing of taxonomy is maily because of the methods'altering from old to new molecular and polyphasic taxonomy, and the latter is in continuously development. Taxonomy of plant pathogenic coryneform bacteria somehow depends on the cooperation of phytopathologists, microbilogists and other scientists.

Objective To observe the effects of static pressure on the number of cultured retinal M?ller glial cells(RMGC)and expression of glial fibrillary acidic protein(GFAP)and heat shock protein(HSP)70 by these cells.Design Experimental study. Participants Cultured rat RMGC.Methods Rat RMGCs were cultured and identified according to previous method described by Reichenbach.These cells were treated with different static pressures and divided into 4 groups:A(1.33kPa),B(2.67kPa),C(5.33kPa)and D(10.67 kPa)while the cells without treatment was as control group(NC).The morphologies of RMGC in these groups were observed under inverted phased contrast microscope,the number of RMGC counted with conservative method and the viability were studied with trypan blue staining.The expressions of GFAP and HSP70 in RMGCs were detected with the method of western blot.Main Outcome Measures The morphologies of RMGC,cell number,cell viability.Results There were pressure-dependent changes of RMGC number. The cell number of group C and D was less than that of group NC,A and B(P＜0.01).High static pressure resulted directly in the decreased ratio of unstained RMGCs(P＜0.01).The ratio of unstained RMGCs in group C and D was less than that in group NC,A and B(P＜0.01).Many cells in group C and D were injured and the higher the pressure elevated,the more the degree of injury became.The expressions of GFAP and HSP70 in group NC were less than other pressure treated groups and the expression of GFAP in group C and D was higher than that in group A and B.There was no obvious difference between these pressure treated groups.Conclusions High static pressure could cause the injuries of RMGCs.The increased expression of GFAP and HSP70 in RMGC might be regarded as a sign of retinal injury response to high intraocular pressure.
