Objective To investigate whether there is a thinning of the retinal nerve fiber layer (RNFL) in the eyes of diabetic patients and to analyze the relationship between RNFL thickness and several diabetic risk factors. Methods Forty-two type 2 diabetes mellitus patients aged 47-70 years were enrolled in this study. All the subjects underwent ophthalmologic examinations and glaucoma diagnosis (GDx) nerve fiber analyzer scanning with two different modes: variable cornea compensation (VCC) and enhanced cornea compensation(ECC).The GDx parameters included the temporal-superior-nasal-inferior-temporal average (TSNITave), superior and inferior averages, the TSNIT standard deviation and the nerve fiber indicator (NFI). The receiver operating characteristic (ROC) was applied to study the diagnostic ability of indices. The association between risk factors and the NFI was studied. Results The area under the curve for the ROC of the NFI was the largest for both the ECC and VCC modes. There was a significant relationship between age and RNFL thinning. However, there was no significant association between diabetic duration and fasting blood glucose with RNFL thinning. The influence of age on NFI was greater in diabetic patients than in control subjects. Conclusions Age has an important influence on the NFI of diabetic patients. Diabetic patients with normal ocular fundus may have RNFL thinning.

Objective To evaluate the association of age and retinal nerve fiber layer (RNFL) thickness by means of scanning laser polarimetry in a sample of healthy Chinese eyes. Methods One hundred and fifty eyes of 150 healthy subjects underwent RNFL scan in two different modes (Variable Cornea Compensation,VCC;Enhanced Cornea Compensation,ECC) of Glaucoma Diagnosis Variable Cornea Compensation Nerve Fiber Analyzer.The parameters included temporal-superior-nasal-inferior-temporal (TSNIT) average,superior average,inferior average,TSNIT standard deviation,and nerve fiber indicator (NFI). Results Mean values of TSNIT average,superior average,inferior average,TSNIT standard deviation and NFI in VCC mode were (57.12±6.26),(69.35±4.21),(67.59±7.06),(25.46±4.02),(17.35±7.59),while the parameters' values in ECC mode were (56.15±5.32),(68.24±6.63),(66.90±2.40),(24.80±6.76),(18.84±8.51),respectively.The differences between the values of VCC and ECC modes were not statistically significant.The parameters' values of total subjects were associated with age.But there were no significant associations between age and parameter values in the eyes of those older than 40 years old subjects. Conclusions There are no significant differences between the RNFL values detected by VCC and ECC modes in 150 healthy Chinese eyes.Age has influence on RNFL thinning in 21-70 years old healthy eyes,but not in the eyes of older than 40 years old people.

Objective To explore the differences of nerve conduction of lower limbs in general population with different nationalities in Xining region.Methods Physical examination and healthy volunteers in No.1 People's Hospital of Xining were collected.Two hundred and forty Hui people of them was Hui group.Two hundred and forty people with other ethnic minorities including Tibetan,Tu and Mongolian of them was mixed group.Two hundred and forty Han people of them was Han group.The nerve conduction of lower limbs in all the people were detected.And the differences were compared.Results The differences of nerve conduction of posterior tibial nerve among all the groups were not statistical significant (all P>0.05).The latent period of common peroneal nerve in Hui group was significantly longer than mixed group and Han group,the motor conduction velocity of which was significantly slower,the motor nerve action potential of which was significantly reduced (all P<0.05).The latent period of superficial peroneal nerve in Hui group was significantly longer than mixed group and Han group,the sensory conduction velocity of which was significantly slower,the sensory nerve action potential of which was significantly reduced (all P<0.05).The differences of nerve conduction of sural nerve among all the groups were not statistical significant (all P>0.05).The differences of nerve conduction of each group among different age periods were statistical significant(all P<0.05).Conclusions The nerve conduction of lower limbs in general Hui people in Xining region must be different with other general people.It must be noticed in clinical examination.

Objective To investigate the effect of glutathione on serum IL-6, IL-8 and TNF-α levels in severe acute pancreatifis (SAP). Methods Thirty-six patients with SAP were randomly divided into glutathione treatment group and non-glutathione treatment group. Age-matched controls were enrolled from healthy volunteers. Serum levels of IL-6, IL-8, and TNF-α were measured within 24 h of admission and the seventh day after admission. Results The serum levels of IL-6, IL-8, and TNF-α in SAP patients were (81.34±5.99)ng/L, (97.81±15.61) ng/L and (28.21±1.53)ng/L, respectively, which were significantly higher than (16.69±2.86) ng/L, (26.42±1.59) ng/L and (15.89±1.41) ng/L in control group (P＜0.05). Seven days later, the serum levels of IL-6, IL-8, and TNF-α in glutathione treatment group were (31.21±3.88)ng/L, (35.51±1.27)ng/L and (16.15±1.31)ng/L, respectively, and those in non- glutathione treatment group were (53.88±6.21 ) ng/L, (51.91±9.88) ng/L, (17.88±1.51 ) ng/L, redpectively. The serum levels of IL-6, IL-8, and TNF-α at the seventh day after treatment were lower than those before treatment and the decrease in glutathione treatment group was more significant (P＜0.05). Conclusions Glutathione may reduce the serum levels of IL-6, IL-8, and TNF-＜ and may play a role in the treatment of SAP.

Objective To evaluate the methods of carrying out radiotherapy quality control (QC) and quality assurance (QA) in the whole province. Methods From 1995, radiotherapy quality control center of Zhejiang province (the guiding team consists of specialists in radiation oncology of the province) has carried out a QC and QA program including evaluation of administration, departmental infrastructure, equipment, staff and treatment for 28 centers in the whole province. The regulation and scoring system were designed and first informed to every center, with the 28 centers checked and examined by the guiding team from 1999 to 2000. Results Great variations in equipment and staff were observed among participating centers. Equipment condition was not very satisfactory. Most of the treatment protocols were reasonable except that the indication for radiotherapy was not strict enough in some centers. Conclusions It is feasible for the radiotherapy quality control center to check and examine the department of radiation oncology in the whole province. Good QC and QA is invaluable to standardize the treatment protocol and ensure the radiotherapy quality and also helpful to carry out multi center study in the future.

Aim ToconstructHEK293cellsstablyex-pressing corticotropin releasing factor receptor 1 ( CRFR1 ) , and evaluate its function by the cAMP as-say.Methods CulturedHEK293cellsweretransfect-ed with CRFR1-expressing vector by Lipofectamine 2000 and were selected by using G418 . CRFR1 ex-pression was detected by Western blot, RT-PCR and immunofluorescence.Results Westernblot,RT-PCR and immunofluorescence data revealed that the HEK293 cells expressed CRFR1 protein stably. The dose-responsive relationship experiment revealed that CRF induced a CRFR1-mediated cAMP production in HEK293 cells with EC50 =(5. 64 ± 0. 05) × 10 -10 mol ·L-1.Conclusion HEK293celllinesstablyex-pressing CRFR1 were constructed successfully, which would provide a cellular model to facilitate the research on the biological function of CRFR1 and CRFR1-targe-ted drug screening.

Objective To quantitatively assess anterior chamber angle of primary angle-closure glaucoma (PACG) and primary angle-closure (PAC) patients after laser pheripheral iridotomy (LPI) by spectral-domain anterior segment optical coherence tomography (SD-AS-OCT),and investigate which parameters should be used in these patients and the clinical significance of these parameters in screening and follow-ups of glaucoma.Methods Fifty-five eyes of 40 patients diagnosed with PACG remission (11 eyes,8 patients),PAC (20 eyes,20 patients) or PAC suspect (24 eyes,12 patients) were examined.Each eye was examined by SD-AS-OCT at upper,lower,nasal,and temporal sides.Anterior chamber angle (ACA),trabecular iris angle (TIA),and trabecular iris space area (TISA500/750) were measured or calculated.All results were analyzed.Results The points from the inside to the corneal scleral spur 500 μm and 750 pm were selected,AOD,TIA,ACA,TISA at upper,lower,nasal,and temporal sides were measured,which were included into 500 series and 750 series.The mean values of TIA,ACA and AOD in the 500 series and 750 series were the largest in the temporal side and the lowest in the nasal side.The mean values of TISA measurement was the largest in the lower side and the smallest at the upper side.Pearson correlation analysis showed that TIA500 and ACA500 (r =0.799,P =0.00),TIA750 and ACA750 (r =0.799,P =0.00),TIA500 and TISA500 (r=0.919,P =0.00),TIA750 and TISA750 (r =0.920,P =0.00) had positive correlation.With TIA500 as independent variable x and TISA500 as dependent variable y,the regression equation was obtained:y =-0.300 + 0.005x (F =1195,P =0.00),which showed TISA500 and TIA500 were linearly positive correlated.With TIA750 as independent variable x,and TISA750 as dependent variable y,the regression equation was obtained:y =-0.440 + 0.009x (F =854,P =0.00),which showed TISA750 and TIA750 were linearly positive correlated.The coefficient of variation of the 750 series parameters were less than the 500 Series in the four directions.Conclusion SD-AS-OCT is an efficient tool for efficiency evaluation and follow-up during the course of PACG and PAC after LPI.For narrow angles,as the parameters of 750 series parameters have less variability,so 750 series are more recommended in clinical application.
