The characteristics of non-arteritic anterior ischemic optic neuropathy (NAION) include sudden decline of visual acuity, sector-shaped visual field defect connected with the physiological blind spot or hemi-visual field defect, and optic disc edema. Early angiographic abnormalities of optic disc and peripapillary choroidal circulation are important cues for the diagnosis. Angiography combined with visual field test can make the diagnosis more accurate. The pathological mechanism and process of NAION and ischemic cardiovascular/cerebrovascular disease are essentially the same. There are several critical issues in this field we need focus on, including strengthening the cooperation with relevant professional disciplines; improving the ocular ischemia through drugs, intervention and other means; preventing more serious cardiovascular events and intervening in a number of high-risk populations to reduce the incidence of AION.

AIM:To analyse the risk factors of age, sex, course, best corrected visual acuity(BCVA),diopter and fundus features of high myopes with progressive high myopia. METHODS: A total of 167 patients with high myopes were categorized into four groups: group 1,age of 29 years or younger; group 2,between the age of 30 to 49 years; group 3,between the age of 50 to 69 years and group 4,age of 70 years or older. The refractive errors of all patients were measured without cycloplegia with an autorefractometer. Data of the spherical equivalent(SE) of the refractive errors in diopters (D)and fundus examed by direct ophthalmoscope were used in statistical analyses.RESULTS: The number of female was statistically larger than that of male(P＜0.01),also the disease course was correlated to the age. The visual acuity of high myopes significantly decreased as they grew older including the higher incidence of lacquer cracker, submacular hemorrhage, Fuchs spots, chorioretinal atrophy . CONCLUSION: Female maybe a risk factor of high myopia, advanced age is an important factor of visual acuity decrease. High myopes ought to be treated early to delay the progress of myopia and development of macular degeneration.

Objective To investigate the application of laparoscope,duodenoscope and choledochoscope in the treatment of intra-and extrahepatic bile duct stone.Methods The clinical data of 3 16 patients with intraand extrahepatic bile duct stone who were admitted to the Bethune First Hospital from April 2007 to August 2010were retrospectively analyzed.There were 269 patients with cholecystolithiasis and choledocholithiasis,10 patients with cholesystolithiasis,choledocholithiasis and hepatolithiagis,and 37 patients with choledocholithiasis.Laparoscopic cholecystectomy(LC)+laparoscopic common bile duct exploration(LCBDE)+choledochoscopy was applied to patients with hepatolithiasis or with the diameter of common bile duct≥10 mm;endoscopic sphincterotomy (EST)+LC or LC+EST was applied to patients with the diameter of common bile duct between 10 mm and 5 mm and the diameter of cystic duct<5 mm;LC+laparoscopic transcystic common bile duct exploration(TC-CBDE)+choledochoscopy wag applied to patients with the diameter of common bile duct≤5 mm and the diameter of cystic duct≥5 mm.Results The success rate of operation was 96.8%(306/316).A total of 163 patients received LC +LCBDE+T-tube drainage+choledochoscopy,and the mean operation time,expense,duration of hospital stay were 93.6 minutes,2.8×104 yuan and 9.8 days,respectively,and 5 patients had complications postoperatively.Fifty-four patients received EST+LC,and the mean operation time,expense,duration of hospital stay were 45.0minutes,6.6 days,2.3×104yuan,respectively,and 1 patient had complication postoperatively.Sixty-seven patients received LC+EST,and the mean operation time,expense and duration of hospital stay were 40.0minutes,6.1 days,2.4×104 yuan,respectively,and 2 patients had complication postoperatively.Thirty-two patients received one-stage repair of common bile duct and LC+TC-CBDE+choledochoscopy,and the mean operation time,expense and duration of hospital stay were 97.3 minutes,7.3 days and 2.5×104yuan,respectively,and 1 patient had complication postoperatively.A total of 272 patients were followed up for 12 months,except for 6 patients with recurrence of common bile duct stone,no residual stone or biliary stricture was etected.Conclusion Combined application of laparoscope,duodenoscope and choledochoscope has advantages of less trauma,quick ecovery and fewer complications in the treatment of intra-and extrahepatic bile duct stone.

Objective To explore and establish a kind of dissertation evaluation system which can fully reflects the characteristics of academic medical doctoral training.Methods 41 medical doctoral dissertation evaluation systems and related literatures were collected,to get the current situation of this dissertation evaluation system in our country and find the key points of various evaluation systems.A questionnaire survey was conducted among 350 doctoral supervisors coming from 6 universities so as to define the framework and connotation of evaluation indicators.Using the Delphi expert consultation method,the connotation of evaluation indicators and composition as well as the weight of various indicators was improved.Results The doctoral supervisors who participated in the research considered that building the dissertation evaluation system should follow the principle of science,innovation and fairness,and the evaluation frame-work should have secondary index and evaluation elements.The evaluation contents concluded choosing topic,literature review,basic theory and professional knowledge,paper writing,innovation,research ability and academic morals and so on.And on the basis of this,the paper explored and developed a more scientific and comparative dissertation quality evaluation system with medical specialty.Conclusion The cultivation units should take the educational goal of evaluation target and the requirements of awarding degree into consideration,seeking opinions fully to the first-line supervisors and combing quantitative and qualitative evaluation effectively with scientific and operable principles when specifying evaluation system.

Point-of-care testing (POCT) of blood glucose has been widely used for continuous monitoring of glucose in clinic due to high sensitivity, convenience, accessibility and shorter TAT.It has been developed rapidly in recent years. But glucose POCT is often out of control and management from central laboratory and usually it was performed by non-laboratorians.It becomes the growing concerns that how to avoid the discrepancy between POCT results and central laboratory results, how to ensure POCT quality of each batch of blood glucose results, how to solve issues in the application and ensure that patients' results are accurate and reliable. The hospital should put the POCT management under the whole management system and improve the accuracy of POCT to achieve the complete quality assurance. This article introduced the management program experiences of glucose POCT in Huashan hospital according to the JCI accreditation and CAP-LAP.

Cyclic amp receptor protein (CRP) is a global transcriptional factor in many prokaryotes, capable of governing nearly half of the total genes in Escherichia coli. Through the method of error-prone PCR or DNA shuffling, we can first obtain CRP mutant library and then get the expected cell phenotype with enhanced resistance. In this article, we reviewed the following desired phenotype: enhanced tolerance towards oxidative stress, improved osmotolerance, enhanced organic solvent (toluene) tolerance, improved acetate tolerance of E. coli fermentation and improved ethanol tolerance during bio-ethanol production. We then concluded that CRP can also be applied in other host cells to get desired phenotypes. Last, we predicted potential applications of mutant CRP transcriptional factor.

This paper reports the nursing care of 12 patients with idiopathic scoliosis treated with halo-pelvic traction preoperatively which focused on breathing training, traction frame management. One patient suffered from temporary brachial plexus injury and four cases suffered from superior mesenteric artery syndrome. With 14-21 day's traction and nursing care, the correction rate of Cobb angle was 35%-50%,the forced vital capacity was improved by 25%,and all the patients received orthomorphia surgery in time. It is suggested that the patients with severe idiopathic scoliosis treated by halo-pelvic traction could take out-of-bed activity freely. It could not only relieve pain and reduce mental pressure, but also improve the safety of orthomorphia surgery.
