AIM: To investigate the sensibility of pattern visual evoked potential (P-VEP) on the diagnosis of glaucoma in different temporal frequency.METHODS: The P-VEP were recorded in 51 eyes of 30 primary glaucoma (PG) patients, 16 eyes of 13 ocular hypertension (OHT) patients and 46 eyes of 23 age-equivalent normal people using an array of different temporal frequency and then the patients were compared respectively with the normal group.RESULTS: The P100 wave amplitude in OHT group was significantly lowered at 8Hz, and was lowered at all temporal frequency in PG group, especially when the temporal frequency was higher.CONCLUSION: The P-VEP can be abnormal when the PG is still in its early stage, so it can be an index of early diagnosis and this is more obvious when the temporal frequency is higher, especially at 8Hz.

To investigate and analyze the epidemiology of serious corneal ulcer.
● METHODS: A total of 133 serious corneal ulcercases from June 2010 to December 2013 in Xiangya Hospital Affiliated to Central South University were retrospectively reviewed for risk factors, demographic characteristics and diagnosis.
●RESULTS: There were 91 male patients (68. 4%) in the 133 patients. A peak incidence age was from 41 to 60 years old (82 cases, 44. 4%). Most of patients were peasant (77 cases, 57. 9%) and the percentage of the low schooling patients was 85. 0% (113 cases). The number of patients who had been sick was 73 before hospitalization (54. 9%) in all cases. The peak incidence season was January (34. 6%). Average length of stay was 9. 84d. The number of emergency cases was 44 (33. 1%). Most of patient were not only corneal ulcer cases but the hypopyon (92 cases, 69. 2%). The figure of inpatients who received operations was 102 cases ( 76. 7%). And the most of operations was amniotic membrane transplantation (31 cases, 39. 2%). Additionally, this data was classified regard to gender differences.
● CONCLUSlON: The peasant of the middle age and elderly represents a distinct clinical group in the serious corneal ulcer in hospital. Severity, ocular trauma in agriculture and health awareness are the major predisposing factors.

Objective 　To evaluate the value of 99m　Tc-TRODAT-1 SPECT DAT imaging in the early diagnosing of Parkinsons disease (PD).Methods　 Eleven patients (9 PD and 2 possible PD) and eighteen healthy subjects matched by sex and age were studied with 99m　Tc-TRODAT-1 SPECT DAT imaging. Striatum specific uptake of 99mTc-TRODAT-1 was calculated according to the ratio of DAT uptake in striatum (ST) and cerebellum (CB). Results　In the hemi-Parkinsons disease group, the DAT specific uptake of 99mTc-TRODAT-1 was significantly lower (P＜0.01) in contralateral than in ipsilateral striatum to the clinically symptomatic side. There was significant decrease (p＜0.01) of striatum DAT uptake in patients with hemi-PD compared to the controls.Conclusions　99mTc-TRODAT-1 SPECT DAT imaging may help to confirm the diagnosis of PD at the early stage.

OBJECTIVETo evaluate clinical outcomes of fixation for the treatment of radial head fracture with collapse of anterior articular surface.

METHODSFrom March 2006 to January 2013,17 patients with radial head fractures with collapse of anterior articular surface were analysed. According to the Mason classification, there were 12 cases with Mason type II fractures and 5 cases with Mason type III fractures. All the patients were treated with open reduction through posterolateral entrance of elbow joint and Herbert or titanium cannulated screw internal fixation.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 18 months, with a mean of 11.3 months. According to the Broberg and Morrey score system, 2 patients got an excellent result, 12 good and 3 fair. There were no complications such as infection of elbow joint, nerve injury, non-union, traumatic osteoarthritis, heterotopic ossification and elbow instability. However, the postoperative activity range of elbow in the injuried side was less than that in the normal side.

CONCLUSIONRadial head fracture with collapse of anterior articular surface is easily misdiagnosed, and it can be treated with open reduction and internal fixation through posterolateral entrance.

OBJECTIVETo establish osteoblast model, primary cilla model was removed by chloral hyrate, observe effects of osteoblast primary cilla moved on enhancing ALP staining and calcified nodules staining in electromagnetic field.

METHODSThree 3-day-old male SD rats weighed between 6 and 9 g were killed, cranial osteoblast was drawed and adherencing cultured respectively. Cells were subcultured and randomly divided into 4 groups until reach to fusion states. The four groups included chloral hydrate non-involved group (control group), 2 mM, 4 mM and 8 mM chloral hydrate group, and cultured in 37 °C, 5% CO2 incubator for 72 h. Morphology of primary cilla was observed by laser confocal scanning microscope, and incidence of osteoblast primary cilia was analyzed by Image-Pro Plus 6.0 software. Cells in the correct concentration group which can removed cillia most effectively were selected and divided into 3 groups, including control group (C), Electromagnetic fields group (EMFs), and EMFs with 4 mM chloral hydrate group. DMEM nutrient solution contained 10%FBS were added into three groups and cultured for 9 days and formation of ALP were observed by histochemical staining of alkaline phosphatase. After 12 days' cultivation, formation of mineralization nodes was observed by alizarin red staining.

RESULTSCompared with control group and 2mM chloral hydrate group,4 mM chloral hydrate group could effectively remove osteoblast primary cilla (P<0.01). Removal of osteoblast primary cilla could weaken the formation of ALP and mineralization nodes in osteoblast in EMFS. Compared with EMFs group, the area of ALP and mineralization nodes in EMFs with 4 mM chloral hydrate group were decreased obviously (P<0.01).

CONCLUSION4mM chloral hydrate could effectively remove osteoblast primary cilia. Primary cilla participate in EMFs promoting formation of ALP and mineralization nodes in osteoblast and provide new ideas for exploring mechanism of EMFs promoting osteoblast maturation and mineralization.

Objective To examine the prevalence ofHelicobacter pylori in Shanghai and relevant risk factors, evaluate the resistance proifle ofH. pylori isolates to antibiotics used in ifrst-line therapy in two hospitals in Shanghai.MethodsH. pylori were isolated from the biopsy samples of gastric mucosa collected from September 2013 to January 2015. Antimicrobial susceptibility test was performed by E-test method for 131H. pylori strains to 4 antibiotics, clarithromycin, metronidazole, amoxicillin and tetracycline. Results A total of 955 patients receiving gastroscopy were enrolled. And 248 (26.0%)H. pylori strains were isolated from the biopsy samples of gastric mucosa. Overall, 14.5%, 64.1%, 0 and 0.8% of the strains were resistant to clarithromycin, metronidazole, amoxicillin and tetracycline, respectively. Resistance to two drugs was found in 10.7%(14/131) of the strains, and majority (92.8%, 13/14) of which were resistant to clarithromycin and metronidazole.Conclusions The prevalence ofH. pylori in gastric mucosa is rather lower compared with the data reported previously. It is associated with the sex, age and clinical outcome of patients, however, antibiotic resistance profile is not related to these factors.H. pylori eradication therapy should be individualized according to the results of susceptibility test in Shanghai.

AIM: To test the ability of multifocal visual evoked potential (mfVEP) in the detecting of glaucoma by comparing the mfVEP recorded from normal subjects and glaucoma patients.METHODS: The mfVEP of 32 normal eyes (n =21) and of 58 eyes (n =37) with primary glaucoma were recorded with the Vision Monitor electrophysical apparatus by the second kernel analysis and to determine the correlation of the topographic location between them.RESULTS: There were significant variability (the coefficient of variation was 43.05%) in mfVEP RMS amplitude in the normal subjects; The RMS amplitude of eyes with glaucoma were smaller than that of the normal eyes and significantly statistical difference were found in the relatively center (namely the 0° -10° ring zone) and in superior nasal quadrant (P＜0.05) while there were no significantly statistical differences of the latency time between them.CONCLUSION: The normal subjects have large individual variability of mfVEP responses. The RMS amplitude of the mfVEP of glaucomatous eyes descends, especially in center zone and superior nasal quadrant.
