AIM: To investigate clinical effects of local resection of eyelid tumors and pathological examination or frozen section examination as well as the stage I recovery.
METHODS: For all 92 cases 92 eyes of eyelid tumor patients who underwent local resection, reconstruction in stage Ⅰ and routine pathological examination ( 37 cases of suspected malignant tumors using frozen section examination. If it was malignant, excision by Moths surgery) . Using free palate mucosa autograft in stage I or reconstruction by Hughes surgery combined with eye flaps repaired eyelid defects.
RESULTS: The postoperative pathological diagnosis:52 cases were benign tumors, and 40 cases malignant tumors. All cases of eye flaps and hard palate mucosa grafts were survived. Followed up for more than 6mo, no tumor were recurred. The appearance and function of eyelid were satisfactory.
CONCLUSION: In this group of cases, nearly half of eyelid tumors are malignant tumors. It should be treated and operated as early as possible. For suspected malignant tumors, we use frozen section examination to confirm its properties in order to excision cleanly in stageⅠ, reducing the recurrence and metastasis. According to the eyelid defect after resection, we could do repair operation in stage Ⅰ. The inner larger defect is repaired by using hard palate mucosa transplantation or Hughes surgery. The outer layer of the eyelid defect is repaired by using eye flap glide, the free flap, the kite flap, the simple suture, etc. It should be careful when using the hard palate mucosa transplantation in the upper eyelid defect.

OBJECTIVETo compare the therapeutic effects between close reduction and plaster slab fixation combined with plaster external traction and operation for the treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications.

METHODSFrom June 2009 to June 2012, 151 children with closed Gartland III supracondylar humerus fractures were retrospectively studied and divided into two groups, including 87 boys and 64 girls, ranging in age from 1 to 12 years old with an average of 5.3 years old. Among them, 76 children (conservative group) were treated with close reduction and plaster slab fixation combined with plaster external traction; 75 children (operation group) underwent surgical operation. The time of elbow joint function exercise, the healing time of fracture, the function recovery of elbow joint and carrying angle was recorded and analyzed. The therapeutic effects were evaluated by the Flynn criteria system.

RESULTSAll patients were followed up from 6 to 36 months (18.3 months on average). The average time of fracture healing and elbow joint functional exercise of the conservative group was shorter than those of operation group (P < 0.001). Motion range of the elbows and carrying angle of two groups were no statistical difference (P > 0.05). According to Flynn criteria system, in conservative group, the result was excellent in 31 cases, good in 35, fair in 7, and poor in 3; in operation group, 27 in excellent, 30 in good, 17 in fair and 1 in poor; there was no significant difference between two groups in therapeutic effects (P > 0.05).

CONCLUSIONClose reduction and plaster slab fixation combined with plaster external traction in treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications,which has similar effect to surgical treatment, and the time of fracture healing and elbow joint function exercise are significantly shorter.

Objective To elucidate significance of hyperintense vessel signs(HVS)on FLAIR MRI in patients with cerebral infarction. Methods Two hundred and sixty-two patients with cerebral infarction admitted in our hospital were included in this study. We retrospectively defined HVS on FLAIR MRI in these patients in comparison with time of flight(TOF)on MR angiograms(MRA), hyperintense lesions on diffusion-weighted images(DWI). Results HVS on FLAIR MR[were identified in 117 patients with cerebral infarction(45.4%), of which 47 patients(83.9%)were obtained within 24 hours of symptom onset. HVS on FLAIR MRI were detected in 74 patients at sylvian fissure(62.2%), 11 at cortical sulci (9.2% ,11/119),34 at the posterior circulation regions(28.6% ,34/119). HVS on FLAIR MRI coincided well with ischemia of TOF on MRA and lesion patterns on DWI (χ2 test,P<0.01, respectively). Conclusion HVS on FLAIR MRI is helpful to evaluate abnormal major cerebral arteries of patients with cerebral infarction.

Background Vancomycin has been increasingly recommended for the management of endophthalmitis,but few research report has been published about the pharmacokinetics of intravitreal vancomycin up to now.It is necessary to have an exact method to measure the concentration of vancomyein in animal eyes after intravitreal injection.Objective This study was to observe and compare the phamacokinetical process of vancomycin in serum,vitreous and aqueous humor between normal and infected rabbit eyes.Methods Seventy-two healthy adult rabbits were randomly divided into normal group and infected group and 36 rabbits for each.The animal models of endophthalmitis were established by intravitreal inoculation of 2000 CFU/ml staphylococcus aureus in the right eyes of rabbits in the infected group.Once endophthalmitis developed,0.1 ml vancomycin ( 10 g/L) solution was injected into the vitreous of every rabbit.The peripheral blood,vitreous and aqueous humor samples were respectively collected in 4 rabbits for each group at 0.5,2,4,6,12,24,48,72 and 84 hours after injection for detection of vancomycin concentration by high performance liquid chromatography(HPLC-UV).3p97 software was used to create fit parameters of pharmacokinetics.This experiment followed the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission (Version 1988).Results The accuracy of HPLC fitted the detecting request of biological specimen.The concentration-time data of vancomycin in normal rabbit aqueous humor and vitreous was subject to two-compartment model.The pharmacokinetic parameters were separately as following:Cmax was 50.16 mg/L and 751.42 mg/L,t1/2was 51.04 hours and 53.21 hours.The concentration-time data of vancomycin in infected rabbit aqueous humor and vitreous was subject to one-compartment model.The pharmacokinetic parameters were separately as following:Cmaxwas 24.94 mg/L and 687.66 mg/L,t1/2was 11.42 hours and 12.91 hours.The concentration of vancomycin in serum was much lower and almost undectable.The concentration of vancomycin in vitreous was gradually reduced as the prolong of time after injection in both normal group and infected group,but a obvious decline after increased level was scen in aqueous humor.Compared with normal group,the concentrations of vancomycin in both vitreous and aqueous humor were reduced at various time points(P＜0.05,P＜0.01 ).Conclusions HPLC is simple,highly sensitive and specific for the pharmacokinetic analysis of vancomycon.These results indicate that pharmacokinetic parameters of vancomycin alter in pathological condition,which is helpful for us to establish the better treatment guidelines for endophthalmitis.

Objective To compare the clinic features of neuromyelitis optica (NMO) and multiple sclerosis(MS).To compare the positive rate of NMO-IgG in NMO,MS and other related diseases,and determine whether it can be considered as a biomarker for differential diagnosis.Methods Detected serum NMO-IgG in 34 NMO patients,22 MS patients,24 high risk syndrome,5 clinical isolated syndrome,and 35 patients with other neumlogical diseases.Compared the clinic features(onset age,severity,prognosis,MRI lesions,autoimmune antibodies,CSF)of 34 NMO patients and 22 MS patients.Results The onset age of NMO is older than that of MS.It is more severe and with worse prognosis than MS.Longitudinal spinal cord lesions are easily found in NMO.NMO-IgG positive rate in NMO and high risk syndrome patients are 58.8% (20/34)and 45.8%(11/24)respectively,which are higher than that in MS(1/22),clinical isolated syndrome(1/5)and other neurological diseases(1/35;x2=37.2,P<0.01).The positive rate may have a relationship with the length of spinal cord lesions.Condusions MS and NMO are probably different diseases.NMO-IgG positive rate in NMO is significandy higher than that in MS,it can be considered as a biomarker for differential diagnosis.
