AlM:To observe the changes of corneal endothelium after phacoemulsification cataract surgery in different types of cataract patients.
METHODS: Randomly selected age-related cataract, diabetic cataract and cataract of high myopia 30 eyes of 30 cases, respectively, in our hospital. All patients underwent phacoemulsification combined with intraocular lens implantation, corneal endothelial density and the percentage of hexagonal cells were measured by corneal endothelial cell instrument without touching before surgery and one week after surgery.
RESULTS: The difference of the preoperative corneal endothelial cell density and the percentage of hexagonal cells among three groups were not statistically significant (P>0. 05). One week after surgery, the cell density in three groups were respectively 2 496. 86 ± 298. 96/mm2 , 2 379. 51 ± 375. 13/mm2 , 2 425. 38 ± 312. 68/mm2 , the percentage of hexagonal cells were respectively ( 46. 20 ± 12. 03)%, (43. 44±13. 99)%, (44. 35±8. 13)%. Both the cell density and the percentage of hexagonal cells one week after surgery were lower than those before operation. There were significant difference in three groups ( P <0. 05). Both the measurements in diabetic cataract group and cataract of high myopia group after surgery were lower than those in age-related cataract group, the cell density and the percentage of hexagonal cells in diabetic cataract group were lower obviously compared with those in age- related cataract group and the difference was significant (P<0. 05).
CONCLUSlON:The tolerance of corneal endothelial cell to phacoemulsification cataract surgery is lower in cataract with diabetes and high myopia. Corneal endothelium should be assessed preoperatively and protected intraoperatively.

In order to investigate the influence of iron deficiency on the mRNA expression of iron regulatory protein (IRP(2)) mRNA and ferritins (FN) in intestinal mucosa of rat, the animal model of rat with nutritional iron deficiency was established. According to the measurement of serum iron (sI), serum fertitin (sFn) and Hb, the experiments were divided into 4 groups: control group, recessive iron deficiency group, mild iron deficiency group and moderate iron deficiency group. sI was measured by flame assay and sFN was measured by radioimmunoassay, the expressions of irp(2) mRNA and fn mRNA were detected by RT-PCR. The results showed that (1) with aggravation of iron deficiency, the levels of sI and sFN in experimental groups decreased and had significant difference from that in control group, except sI level in the recessive iron deficiency group; (2) with aggravation of iron deficiency, the expression of irp(2) mRNA in duodenum mucosa elevated, and the expressions of irp(2) mRNA in moderate iron deficiency group and mild iron deficiency group were higher than that in control group (p < 0.01), the expression of irp(2) mRNA in moderate iron deficiency group was higher than that in recessive iron deficiency group (p < 0.05), but the expression of irp(2) mRNA did not showed statistical difference between mild iron deficiency group and moderate iron deficiency group (p > 0.05); (3) with aggragation of iron deficiency, the expression of fn mRNA in dudemum mucosa decreased, the expression levels fn mRNA in control and moderate groups were highest and lowest, respectively, there were significant differences between experimental and control groups (p < 0.05), and between experimental groups (p < 0.05); (4) the expression of irp(2) mRNA and fn mRNA in moderate iron difficiency group showed negative correlation (r = 0.662, p < 0.05). It is concluded that IRP(2) protein serves as an important regulator of iron metabolism in the human body, and regulates iron uptake from the intestine by controlling the expression of fn mRNA at the post transcriptional level.

【Objective】 Tostudy the effect of ABO blood group on the FⅧ∶C and Fib content in human plasma, so as to provide the oretical guidance for the quality control of fresh plasma products and the establishment of relevant quality standards. 【Methods】 Samples determined included fresh plasma collected and fresh plasma separated manually. The FⅧ∶C and Fib content were determined by coagulation method. The exon6 of ABO gene was amplified and sequenced to determine the genotype. 【Results】 The FⅧ∶C in fresh plasma collected was (147.421±45.773)%, and that in fresh plasma separated manually was (119.083±35.130)%, showing significant differences(P<0.05). The Fib content in fresh plasma collected was (2.252±0.381)g/L, and that in fresh plasma separated manually was (2.324±0.470)g/L, with no significant differences observed (P>0.05). The FⅧ∶C in non-O type (A, B, AB type) fresh plasma collected and fresh plasma separated manually were (167.048±40.862)% and (129.251±33.503)%, respectively, significantly higher than that in O type fresh plasma collected and fresh plasma separated manually as(121.386±38.632)% and (91.589±22.328)%, respectively. The Fib contents in non-O type fresh plasma collected and fresh plasma separated manually were (2.242±0.385)g/L and (2.329±0.472)g/L, respectively. The Fib contents in O type fresh plasma collected and fresh plasma separated manually were (2.287±0.370)g/L and (2.307±0.462)g/L, respectively, and no significant difference was noticed (P>0.05). 【Conclusion】 There was no significant correlation between Fib content and ABO blood group, while FⅧ∶C was significantly correlated with ABO blood group. In the preparation and quality control of FⅧ related blood products, the effect of ABO blood group on the FⅧ∶C should be considered, and the quality standard of FⅧ in plasma products should be established based on the ABO blood group.

OBJECTIVETo assess the value of cerebral spinal fluid (CSF) and serum myelin basic protein (MBP) levels in the diagnosis of multiple sclerosis (MS).
METHODSEnzyme-linked immunosorbent assay was used to detect the CSF and serum levels of MBP in patients with MS (n=45), patients with Guillain-Barre syndrome (GBS) (n=36) and control subjects (control) (n=33). The sensitivity and specificity of MBP in CSF and serum in the diagnosis of MS were evaluated using the receiver-operating characteristic (ROC) curves.
RESULTSThe MBP levels in CSF and serum both increased significantly in MS group as compared with those in GBS (P<0.01) and control groups (P<0.01). The area under the curve (AUC) of the ROC curve of MBP in CSF was 0.853-/+0.037 for MS diagnosis, and with the optimal cut-off value of 0.87 pg/ml, CSF MBP showed a diagnostic sensitivity of 83.7% and specificity of 78.3%. The AUC of the ROC curve of serum MBP was 0.761-/+0.046, and the optimal cut-off value of 0.25 pg/ml resulted in a diagnostic sensitivity of 62.8% and specificity of 73.9%. No statistically significant difference was found between the two AUCs (P>0.05).
CONCLUSIONEvaluation of CSF and serum MBP levels allows accurate diagnosis of MS, and MBP level in the CSF has greater diagnostic sensitivity than serum MBP. The combination of both CSF and serum MBP levels may serve as a sensitive index for the diagnosis of MS.

Objective To investigate the effect of 131I on apoptosis of thyrocytes in patients with Graves disease. Methods Forty-seven patients with Graves disease were divided into two groups, two week group (G2w) and four week group (G4w). All patients underwent thyoid needle biopsy before 131I treatment and the repeated biopsy at two weeks (G2w) or four weeks (G4w) after 131I treatment. The positive units of pro-apoptotic proteins (Fas, FasL) and anti-apoptotic protein (Bcl-2) were studied with immunohistochemistry staining. The differences of the two groups were compared with t-test. Liner correlation analysis was applied to study the correlation between 131I dose and apoptosis-related proteins and that between serum sTSH after 131I treatment and apoptosis-related proteins. Results Fas, FasL and Bcl-2 expression (positive units) were significantly increased in both groups after 131I treatment, G2w :22.84 ± 9.31 vs 16.20 ± 6.75,21.13±6.29vs 14.56±4.06, 21.69±7.83 vs 15.22 ±5.94, t= -3.08, -3.73, -4.05 (allP<0.05); G4w:21.69 ±4.52 vs 15.83 ±5.03, 19. 11 ±3.75 vs 14.02 ±4.98, 19.06 ±3.44 vs 16.63 ±4. 73, t = - 5.26, - 5.00, - 2.41 (all P<0.05). However, no statistical differences were found between G2w and G4w (t = 0. 53, 0. 82, 1.46, all P > 0.05). Significant correlation was found between 131I 0. 727, rFasL = 0. 763 (both P<0.05)), but not between the dose and Bcl-2, rBcl-2 = - 0. 094, 0. 102(both P > 0.05). There were significant correlation between serum sTSH three months after 131I treatment and apoptosis-related proteins, rFas = 0.433, rFasL = 0. 601, rBcln2 = - 0. 397, (all P<0. 05). Conclusions 131I can induce thyrocytes to express the pro-apoptotic proteins in patients with Graves disease.
