Objective To observe the clinical manifestations and fe at ures of fundus fluorescein angiograms (FFA) of patients with multifocal choroidi tis (MFC). Methods The data of 8 patients who had been diagnos ed by clinic and FFA as with MFC were collected, and their clinical manifestatio ns and results of FFA were analyzed and valued. Results The ag e of the 7 female and 1 male patients ranged from 16 to 32, and all of the 8 pa tients had high myopia (from -6.00 D to -8.00 D) with binocular multiple small yellowish white lesions in posterior pole of the fundus and a few phlogistic ce lls in vitreous body. In addition, macular choroidal neovascularization membrane (CNV) was found in 6 patients, binocular in 2 and monocular in 4. The results o f FFA in 7 patients showed hypofluorescence of the yellowish-white lesions at t he early phase and pigmentation at the late phase; Corresponding manifestations of FFA could be found in the patients attended by CNV surrounded by leakage. Conclusion MFC are mostly diagnosed in young females with myopia. Most of the patients had binocular affection with multiple small yellowish whit e lesions at the posterior pole, whose FFA shows hypofluoresence of the active l esions at the early phase and pigmentation at the late phase. CNV may occur in p atients with MFC.

Objective To evaluate the clinical result of anterior elbow approach and internal fixation for the treatment of capitulum humeri fractures. Methods From January 1997 to December 2003,11 patients of 9 males and 2 females with capitulum humeri fractures were chosen anterorredial approaches of elbow. The fractures were terated with under direct vision and were fixed with screws. The left arms in 7, right in 4, the age of the group were from 14 to 18 years old, with the average of 15 years. 7 cases of them were treated with close reduction but failed. The operative time was from 3 days to 7 days after injury. They were fresh and close fractures. According to wangyicong's classification system all were TypeⅠ. Results All operations were successful, no nerves and blood vessels injury, the incisions were all healed by first intention. The X-ray films shows that the fractures were anatomic reduction. The healing time was 6 weeks in average and all patients were followed up with an average 3.5 years, no postoperative complications such as:myositis ossificans, post-traumatic arthritis, avascular necrosis of capitulum humeri. According to Cassebanm and the percentage of elbow joints pain was measured with patient visual pain index function score system: 7 caese of excellent, 4 case of good. Conclusion Displace of capitulum-trochlea hemeri does not link with muscle and capsula articularis, blood carries supply. Without avascular necrosis probably occurs at far stage. The close manipulation of capitulum humeri fractures hardly succeeds. The treatment with accurate open reduction associated with strong fixation can decrease the rate of avascular necrosis in the capitulum humeri fractures. The capitulum humeri fractures are suitable for opening reduced direct vision and fixing with screws through anteroeedial approaches of the elbow. The patients were encouraged to proceed for active rehabilitation early such as the elbow flexion-extension. Its short-term clinical outcomes is more excellent.

Objective To evaluate glaucoma and anterior chamber angle changes after intravitreal silicone oil injection(SOI). Methods The intraocular pressure(IOP) and anterior chamber angles of 34 eyes(33 patients)undergone pars plana vitrectomy and SOI were observed. Results Glaucoma occurred in 9 eyes(26%),in which silicone oil glaucoma(SOG)accounted for 77%(7/9).The changes of the superior part of anterior chamber angle were peripheral anterior synechiae in 11 eye(32%) and SO emulsification droplets in 22 eyes(64%) in 1～4.5 months after surgeries.Glaucoma occurred in 6 eyes of 7 eyes undergone peripheral iridectomy at the inferior part of the iris after the closure of iridectomy holes(P

Objective To investigate the prognostic factors of life and functional outcome of the first hemiparetic stroke patients. Methods One hundred and eighteen stroke subjects were registered prospectively. The Barthel index (BI) , Rankin scale (RS) , Mortricity index(MI) , Mini-mental state examination (MMSE) , Montgomery-Asberg depression scale (MADRS) and a scale of general state and risk factors were used to evaluate at the 48th hour, the 15th day and the 90th day after stroke. Results The patients' performance, as demonstrated by their scores with all the evaluation instruments, changed significantly at all the time points of evaluation after stroke (P ＜0.05). There was no significant difference between the performance at the 48th hour and the 15th day after stroke ( P ＞ 0.05 ). But at the 90th day after stroke, the activity of daily living performance and the depression status recovered significantly (P ＜ 0.01 ). Logistic regression analysis showed that, such factors as pneumonia, urinary incontinence within 48th hour and deep sensation disturbance might adversely influence patients' activity of daily living performance at the 90th day after stroke; the muscle strength of upper extremities at the 48th hour, and MMSE scores at the 15th day after stroke acted as the protective factors. Conclusions The stroke patients improved significantly with regard to their clinical and functional manifestations when evaluated 90 days after stroke onset. The main factors influencing the activity of daily living performance 90 days after stroke onset included deep sensation disturbance,pneumonia, urinary incontinence and muscles strength of upper extremities at 48th hour, and MMSE scores at the 15th days after onset.

BACKGROUND:Recently, a neuroprotective effect of granulocyte colony-stimulating factor was reported in a model of cerebral infarction and a model of acute spinal cord injury. However, the applied animal model was not established by impact method, different from pathophysiological process of human.
OBJECTIVE:To observe effects of granulocyte colony-stimulating factor on motor function in a rat model of spinal cord injury induced by Al en’s method.
METHODS:Wistar rats were used to establish spinal cord injury at T 10 level using modified Al en’s method. They were randomly assigned to two groups, granulocyte colony-stimulating factor group, treated with granulocyte colony-stimulating factor, and vehicle group, treated with equal volume of PBS. The motor function was evaluated with Basso-Beattie-Bresnahan score and modified Rivlin loxotic plate test monitored at 1, 7, 14, 21, 28 and 35 days, and four-limb muscle strength was assessed using Grid walk test at 7, 14, 21, 28 and 35 days post-operatively.
RESULTS AND CONCLUSION:Hind limbs paralysis occurred in al animals postoperatively. Scores of Basso-Beattie-Bresnahan and modified Rivlin loxotic plate test were greater in granulocyte colony-stimulating factor group compared with vehicle group at 7, 14, 21, 28 and 35 days (P<0.05-0.01);mean Grid walk test errors were less in granulocyte colony-stimulating factor group compared with vehicle group at 14, 21, 28 and 35 days (P<0.05-0.01). Results indicate that motor function and four-limb muscle strength were improved fol owing granulocyte colony-stimulating factor therapy compared with vehicle group, indicating that granulocyte colony-stimulating factor has a positive effect on spinal cord injury.

Objective:To search for a better RT-PCR method for detecting CK19 mRNA. Methods: RT-PCR methods were used to detect the expression of CK19 mRNA in the tumor tissues and in the peripheral blood of patients with gastric cancer and in the peripheral blood of healthy subjects. Results: The influence of pseudogene and genome was observed through nonreversely transcripted RNA controls and comparison of several pairs of primers.The interference could be effectively eliminated by regulating the annealing temperature based on mismatched primers. Conclusion: The presence of pseudogene and genome interferes the experimental protocol in RT-PCR,which can be resolved with the method introduced in our paper.

Objective To develop a method for determination of 18 organophosphorous and carbamate pesticides in human plasma by UPLC-MS/MS. Methods Following deproteinization by acetonitrile, an aliquot of the biological sample was injected into a C18 column(1.7μm 2.1×50mm) using 5mmol/L Ammonium acetate-methanol as the mobile phase with the flow rate of 0.3mL/min, the injection volume was 10μL. Electro spray ionization(ESI) Indicators source was applied and operated in positive ion mode, and multiple reaction monitoring(MRM) mode was used to quantify. Results The limits of detection(LODs) in human plasma ranged from 0.1 to 40ng/mL, and the limits of quantitation(LOQs) ranged from 0.5 to 50ng/mL. An excellent linearity was observed for these LOQs up to 50ng/mL. The average extraction recoveries were with in 64.3%~111.9%, relative standard deviation(RSD) is 3.9%~10.3%. Conclusion This method is specific, sensitive and accurate, and can be used to detect pesticides in forensic.

Objective To illustrate and discuss the technique and clinical value of scapula Y-position radiography.Methods Scapula Y-position radiographies were performed on 110 patients with shoulder joint injury or omalgia.The patient standed in front of the panel face to face, with the affected joint closed to the panel, and the arms fell naturally and palms pronated to stick close to the body.The angle between the coronal plane and the panel was about 55 to 65 degree, put the affected caput humeri at the center of the panel,tilted the tube to foot-side by 15 degree,and aimed the axis at caput humeri.Results Among the 110 patients, 82 radiographies were successfully taken by the first time,28 failed because of the inappropriate body-tilt angle.We had exposed 5 acromion fractures cases, 20 flexural and hook-form acromion cases, 35 cases with the acomion-caput humeri distance less than 1 cm, and 2 coracoid fracture cases.Conclusion Scapula Y-position radiography has high clinical value that could expose the osseous anatomic exit of the rotator cuff and guide the clinical treatments.
