Objective To explore the relationship between apolipoprotein E ( ApoE ) genotype and diabetic nephropathy (DN) in Chinese Han population of Guangdong province. Methods 63 cases of DN patients were selected as group A; 57 diabetes patients without complications as group B; 55 healthy persons as group C. ApoE genotype of all objects were measured. Results ApoE2 in the group A was the highest, while the differences in other groups were not obvious. Detection of ApoE3 and ApoE4 was not obvious in three groups. The Level of triglyceride (TG) was highest inε2 group, and the level of total cholesterol (TC) and low density lipoprotein LDL-C were highest in ε4 groups. Conclusions In Chinese Han population of Guangdong province , ApoE gene polymorphism and DN are closely interrelated , and the occurrence ofε2 is proportionate to DN.

AIM: To evaluate the efficacy of phacoemulsification and intraocular lens implantation surgical intervention of complicated cataract in patients with uveitis.
●METHODS:Retrospective study. A total of 57 cases (57 eyes ) with complicated cataract with uveitis were involved in the study from Jan. 2015 to Dec. 2015. All cases underwent phacoemulsification and intraocular lens implantation surgery successfully. The postoperative reaction, effect, complications and so on were retrospectively analyzed after phacoemulsification and intraocular lens implantation surgery. The date of visual outcome was analyzed using Non - parametric Wilcoxon test.
●RESULTS: lris were bleed in 21 eyes ( 37%) , 4 eyes ( 7%) with posterior capsule rapture and posterior chamber intraocular lens was not implanted in 4 eyes ( 7%) . The uncorrected visual acuity ( UCVA ) was significantly increased after surgery. The UCVA of 8 eyes (14%) were 0. 1 or better before surgery, and the UCVA of 42 eyes (74%) were 0. 1 or better 3mo after surgery, the difference was statistically significant ( Z=23. 42, P<0. 001). The corneal edema (17 eyes, 30%), uveitis (2 eyes, 4%) and intraocular hypertension ( 1 eyes, 2%) were appeared in postoperative 1d. The corneal edema (3 eyes, 5%) was appeared in postoperative 1wk. The uveitis ( 1 eyes, 2%) was appeared in postoperative 1mo. The corneal edema (1 eyes, 2%), uveitis (2 eyes, 4%) , intraocular hypertension ( 1 eyes, 2%) and after-cataract ( 3 eyes, 5%) were appeared in postoperative 3mo.
● CONCLUSION: The phacoemulsification combined intraocular lens implantation surgical intervention of complicated cataract in patients with uveitis has good effect and fewer complications.

Objective To explore the therapy measurement of iron deficiency anemia(IDA)associated helicobacter pylori(HP)infection among children.Methods Eight hundred and ninty nine cases entrusted children aged from 2 to 7 years old were measured hemoglobin(Hb),mean corpuscular volume(MCV)mean corpuscular hemoglobin(MCH),mean corpuscular hemoglobin concentration(MCHC)and serum ferri,serum fettin(SF),HP-IgG antibodies.Divided the HP-IgG positive cases into two groups for treatment,The treatment group adopted omeprazole,amoxicillin and metronidazole to cure them for two weeks,then oral ferrous sulfate sugar liquid.The contrast group purely take the ferrous sulfate sugar liquid.After eight weeks re-examined the Hb and SF.Results Totally 279 cases were diagnosed as Hp-positive,620 as HP-negative and 99 children diagnosed as IDA,among the 99 cases IDA,58 cases with HP infection(20.8%) and 41 cases with non-HP infection(6.7%).That means the number of IDA cases with HP infection was higher than those with non-HP infection(?2=39.46 P

Background The biomeasurement and imageology of retinal nerve fiber layer(RNFL) thickness showed the damage of retinal structure in the early and middle stage of glaucomatous eye,however,the subtle functional damage of glaucoma can not be timely reflected only with automatic static perimeter.Microperimetry is a method of quantitatively assessing mean sensitivity (MS) of macular zone.Objective This study was to evaluate and compare the macular functional change in early and middle stage of primary open angle glaucoma (POAG) and chronic angle-closure glaucoma (CACG) with MP-1 microperimeter.Metbods This trail protocol was approved by Ethic Committee of Peiking University Third Hospital,and written informed consent was obtained from each subject prior to entering the study group.A cross-sectional and case-controlled study was designed.A total of 126 eyes from 126 subjects were enrolled in the trail,including 53 eyes of 53 normal subjects,50 eyes of POAG patients and 23 eyes of CACG patients.A macular 10° program was set with MP-1 microperimetry to record the MS of various subareas.The macula was zoned into central 2°,6°,and 10° visual fields and 4 quadrants in each ring.The MS of different rings and subareas was detected and compared among POAG patients,CACG patients and normal controls.Results The MS values of central 2°,6°,10° and whole macular area were (15.09 ± 3.03),(15.72 ± 3.22),(13.99 ± 3.63) and (14.91±3.07)dB in the POAG group,which were significantly lower than those of (17.29±1.59),(18.05±1.24),(16.76±1.89) and (17.37±1.46)dB in the normal control group (all at P=0.000).The MS values of central 2°,6°,10° and whole macular area was (16.00±2.39),(15.83±2.63),(14.45±3.15) and (15.42±2.54) dB in the CACG group,and the reduced MSs were seen at the 6°,10° rings and whole macular area in the CACG group compared with the normal control group (P =0.004,0.013,0.011).Within the 6° ring,the MS values in the inferotemporal quadrant were declined in the POAG group and CACG group compared with the normal control group (P =0.000,0.022),but the difference was not statistically significant between the POAG group and the CACG group (P =0.311).In addition,the MS value in the inferonasal quadrant was significantly lower than that of the normal control group (P =0.005); while that in the CACG group was not significantly different in comparison with the normal control group (P=0.119).In the POAG group,the MS value of the inferotemporal quadrant was significantly lower than that of the superonasal or superotemopral quadrant (P =0.043,0.016),but no significant differences were found among the 4 quadrants in the CACG group (all at P>0.05).Conclusions The mild damage of retinal function appears in the early and middle stage of POAG and CACG.More serious MS reducing occurs in the inferotemporal and inferonasal quadrants of POAG.

Objective To study the relationships between serum intedeukin-18(IL-18)and resistin for predicting intraamniotic infection.Method Serum levels of IL-18 and resistin were measured in 43 pregnant women with intraamniotic infection (infection group)and 40 normal pregnant women(control group).Results The level of IL-18 in infection group[(38.7±10.4)μg/L]was higher than that in control group [(23.5±5.6)μg/L],there was significant difference between two groups (P<0.01).The level of resistin in infection group[(24.84±5.32)μg/L]was higher than that in control group[(17.3±5.15) μg/L],there was significant difference between two groups(P<0.01).The levels of resistin and IL-18 were correlated in pregnant women with intraamniotic infection(r=0.61,P<0.01).Conclusion Detecting the levels of IL-18 and resistin in pregnant women can identify intramnniotic infection.

Objective:To establish a simple HPLC method for the determination of warfarin in human plasma and analyze the re-sults of 100 monitoring reports. Methods:Warfarin was extracted from the plasma samples by acetonitrile. The extract was separated on a ZORBAX Eclipse XDB-C8 column (150 mm × 4. 6 mm, 5 μm)with a mobile phase consisting of methanol and 0. 1% acetic acid (65∶35) at flow rate of 1. 0 ml·min-1 and detected by a diode array detector. The detection wavelength was at 308nm and the sample size was 20 μl. Results:The calibration curve was linear within the range of 0. 1-5. 12μg·ml-1 . The average recovery and RSD was ranged from 85. 0% to 102. 3% and 1. 2% to 3. 9%(n=6), respectively. Inter-and intra-day RSD were 1. 1%-1. 8% and 1. 6%-2. 9%, respectively. Conclusion:The proposed method is rapid, convenient and accurate in the detection of warfarinin concentration in plasma.
