Objective To retrospectivly analyze the value of Pap smear,liquid-based cells, colposcopy and colposcopic cervical biopsy in the diagnosis of cervical cancer. Methods 116 cases of cervical cancer were retrospectively analyzed, and the value of Pap smear,liquid-based cells ,colposcopy,and colposcopic cervical biopsy in the diagnosis of cervical cancer were investigated. Result 116 patients were pathologically diagnosed with cervical cancer before and after surgery. Pap smear was performed for 30 patients (25.9%) ,and 10 patients (33.3%) were detected with HSIL. Liquid-based cells was performed for47 patients (40.5%) ,and 25 patients (53.1%) were detected with HSIL. Colposcopy was performed for 99 patients (85.3%), and 75 patients (75.8 % ) were detected with HSIL or invasive cancer. Preoperative colposcopic biopsy was performed for 99 patients, and the pathological coincidence rate was 94.9%. There was no significant difference statistically between two cytology screening ( P > 0.05 ). There was significant difference statistically between liquid-based cells and colposcopy ( P < 0.01 ). There were significant differences statistically among liquid-based cells,colposcopy ,and colposcopic cervical biopsy ( P <0.01 ). Conclusion Cytology, colposcopy, colposcopic cervical biopsy could not be individually more complete and accurate detection of cervical cancer. Colposcopy,colposcopic biopsy than cytology had higher accurate rate of diagnosis of cervical cancer. A reasonable combination of multiple detection methods could improve the diagnostic accuracy of cervical cancer.

Objective To analyze the polymorphisms of glycosylphosphatidylinositol-specific phospholipase D (GPI-PLD) gene Exon1 and Exon25,GPI-PLD activity of leucocyte in peripheral blood and their relationship in systemic lupus erythematosus patients of Han nationality in Hunan Chinese.Methods The polymorphisms were analyzed by PCR-SSCP and sequencing. GPI-PLD levels were determined by using glycosylphosphatidylinositol (GPI) anchored placental alkaline phosphatase (PLAP) as substrate and triton-X114 partioning.Results There were fourteen variations in the coverage of GPI-PLD gene Exon 1 of both 109 healthy persons' and 62 systemic lupus erythematosus patients',including seven variations at transcriptional start site upstream and seven variations at Exon1. The codons of variation were 14TTG→AAG (Leu14Lys),17CTC→GTC (Leu17Val),20AGA→AAA (Arg20Lys),21GGT→GGG (Gly21Gly),30GTA→ATA (Val30Ile),which leaded to four missense mutations and one synonymous mutation. In addition, the frequency of the variation at transcriptional start site upstream -24 C→T was significantly different between healthy control and systemic lupus erythematosus patients. At meanwhile, there was a variation in Exon25, the +60496 G→A, between two groups. The total various frequency, which was determined by SSCP, of healthy person was 33 03 percent and systemic lupus erythematosus patient was 25 81 percent. On the basis of the percentage of GPI-anchored PLAP conversion, the leucocyte GPI-PLD activities of total 62 systemic lupus erythematosus patients were measured. As compared with 109 healthy persons as control group, the leukocyte GPI-PLD activities of systemic lupus erythematosus patients were significantly raised, but GPI-PLD activities were not correlated with polymorphism sites significantly.Conclusions The leukocyte GPI-PLD gene in peripheral blood, which belongs to healthy persons and systemic lupus erythematosus patients of Han mationality in Hunan Chinses,is polymorphism.The frequency of transcriptional start site upstream -24 is significantly different between healthy control and systemic lupus erythematosus patients.The leukocyte GPI-PLD activeties of patients' also significantly increase.

AlM: To compare the effects of external approach microsurgery and conventional external approach surgery for retinal detachment ( RD) .METHODS: From January 2010 to January 2013, 60 patients (60 eyes) in our hospital were randomly divided into experimental group (29 cases, 29 eyes) and control group ( 31 cases, 31 eyes ) , the external approach microsurgery and conventional external approach surgery were performed respectively ( by the same skilled doctor ) . Retinal reattachment rate, visual acuity improvement rate and operative time were compared between two groups.RESULTS:lt cost shorter time for the external approach microsurgery than that of conventional external approach surgery ( P = 0. 0087 ). The once successful retinal reattachment rate in experimental group was 93% ( 27 cases ) , which was higher than that in control group (90%, 28 cases), there was no statistical difference. The vision improvement rate in control group was 86% ( 25 cases ) , compare to 90% ( 28 cases ) in experimental group, there was no statistical differences. CONCLUSlON: No statistical differences showed in visual acuity improvement and the once retinal reattachment rate between the two groups for rhegmatogenous retinal detachment. However, it is believed that external approach microsurgery could be faster, easier to learn with satisfactory effect.

AIM: To comprehensively investigate the current status of cataract surgery in Leshan city, and find the existing problems according to the survey results as a guide to cataract prevention and treatment in future.
METHODS: We surveyed the status of cataract surgery containing equipments, surgeons and surgery conditions in 17 ophthalmology departments of general hospitals from Leshan including 6 counties, 1 county-level city and 4 districts during 2012. Cataract surgery methods, according to various surgery financial resources, surgical performances and surgical incision, were divided into phacoemulsification and intraocular lens implantation ( Phaco + IOL ) , extracapsular cataract extraction and intraocular lens implantation ( ECCE + IOL ) , and each method contained 2 groups. We analyzed the outcomes following preoperative examination, surgeons, surgical methods, surgical equipments, types of IOL, surgical quantity, surgical results, and intraoperative complication.
RESULTS: In whole city there were 16 operating microscopes, 43 slit lamp microscopes, 12 non-contact tonometers, 1 intraocular lens Master, 8 optical A/B type ultrasonic examination systems, 4 YAG lasers and 12 phacoemulsification instruments. There 15 doctors could complete cataract surgery independently, and 5 of them were phacoemulsification surgeons. The total number of completed cataract surgeries reached 6 211 eyes, containing 3 564 eyes for Phaco+IOL ( 57%) ( preoperative visual acuity ≥0. 3 in Phaco+IOL1 were 1 520 eyes, 24%) and 2 647 eyes for ECCE+IOL ( 43%) ( 1 533 eyes in ECCE+IOL1, 25%). In various groups, off-blindness rate was 94. 80%-100%, off-disability rate was 90. 41%-100%, and 94. 96% - 100% received intraocular lens implantation, intraoperative complication rate was 1. 00%-15. 10%.
CONCLUSION: The distribution of surgeons and equipments in the whole city is unbalanced, and the utilization rate of phaco equipment is low. The levels are different in various hospitals on surgical technique, surgical quantity and surgical results. Phacoemulsification and intraocular lens implantation is considered as the main therapy for cataract, and as a transition to dioptric and personalized cataract surgery. The surgical condition of the city is good, but the proportion of cataract surgery for prevention of blindness in Leshan city is low, and the surgical technique remains to be further improved.

Objective To characterize mycosis fungoides (MF)-associated serum proteins by surface enhanced laser desorption/ionization time of flight-mass spectrometry (SELDI-TOF-MS) technique. Methods Serum samples were collected following informed consent from 15 patients with MF and 15 patients with chronic eczema or neurodermatitis. Serum protein profiles were detected by CM10 protein chip combined with SELDI-TOF-MS. The proteins differentially expressed between MF and chronic eczema or neuroder matitis were assessed by the Zhejiang University Cancer Institute - ProteinChip Data Analysis System (ZUCIPDAS). Results A total of 329 protein peaks were detected from these patients, significant difference was observed in only 30 protein peaks. The optimal diagnostic model was developed by support vector machine algorithm with two protein peaks at Mass/Charge (m/z) 3939 and 5909 respectively. The expression of protein peak at m/z 3939 was higher in chronic eczema and neurodermatitis than in MF, while that at m/z 5909 appeared to express in an opposite way. In simulation training, this model proved to be able to distinguish MF from chronic eczema and neurodermatitis with both the specifity and sensitivity being 100 percent. The leave-one-out cross-validation also revealed a specificity and sensitivity of 100 percent for this model in the comparison of MF with chronic eczema and neurodermatitis. Conclusion These results suggest that SELDITOF-MS technique combined with bioinformatics is highly specific and sensitive in the diagnosis of MF.
