AIM: To discuss the single application on iris localization technology in excimer laser for the treatment of astigmatism.
METHODS:Totally 203 cases (406 eyes) of laser in situ keratomileusis ( LASIK ) in the treatment of compound myopic astigmatism patients were operated from November 2011 to November 2012 in our hospital. They were divided into two groups. One was observation group using iris localization and the other was control group using routine operation. Patients in the observation group of 100 cases ( 200 eyes ) , aged 18-43 years old, spherical diopter was - 1. 25 to - 8. 75D, astigmatism was -1. 0 to -3. 25D. In control group, 103 patients ( 206 eyes ) , aged 19-44 years old, spherical diopter was -1. 75-9. 50D, astigmatism was -1. 0 to -3. 25D. The patients in the observation group before the application of WaveScan aberrometer check for iris image, spherical lens, cylindrical lens and astigmatism axis data operation, only single application of iris location, without using wavefront aberration guided technology, laser cutting patterns for conventional LASIK model, spherical, cylindrical mirror and astigmatism axis  RESULTS: Postoperative residual astigmatism, the observation group was significantly better than the control group. Astigmatism axial measurement after operation, the observation group was significantly less than that of the control group. Postoperative visual acuity at 6mo, the observation group was better than that of the control group. The difference was statistically significant.
data source to preoperative wavefront aberration results. The control group received routine LASIK. It was applicated comprehensive optometry optometry respectively to examine astigmatism and axial, based on the computer analysis during the preoperative, 1wk after the operation, and 6mo. Analysis of using SPSS 17 statistical software, it was independent-sample t test between the two groups of residual astigmatism and astigmatism axis.
CONCLUSION: For patients who cannot complete the wavefront aberration guided treatment of astigmatism, can separate the application of wavefront aberration analyzer automatic iris recognition technology to improve precision of astigmatism treatment, give full play to advanced technical performance of equipment, which has good application value.

Objective To determine the protein expression of P14ARF,MDM2 and mutant type P53 (P53mt) in skin specimens of coal-burning-type of endemic arseniasis patients and to reveal the molecular mechanism of the disease.Methods Sixty skin specimens from 60 endemic arseniasis patients including 35 of skin lesions patients,19 of precancerous lesion and 6 of skin cancer and 9 normal skin specimens from non-cancer patients were studied.Expression of P14~,MDM2 and P53mt was evaluated by immunohistochemistry using corresponding monoclonal antibodies.Results There was significant difference in the positive rates of P14ARF,MDM2 and P53mt among the 4 groups(x2 =9.39,6.21,20.64,all P ＜ 0.05).The positive rates of P14ARF in precancerous lesion and skin cancer specimens were 46.1％ (6/19) and 33.3％ (2/6),respectively,which were significantly lower than that of the normal skin specimens [88.9％(8/9),all P ＜ 0.05].Decreased expression of P14ARF was correlated with the development of dermopathy (P ＜ 0.05).The positive rates of MDM2 and P53mt in skin lesions,precancerous lesion and skin cancer specimens were 54.2％ ( 19/35 ),63.2％ (10/19),66.7％ (4/6) and 25.7％(9/35),73.7％(14/19),83.3％(5/6),respectively,which were significantly higher than those of the control (0,0,all P＜ 0.05).The expression of MDM2 and P53mt increased with the development of dermopathy(all P ＜ 0.05).Conclusions P53mt protein in skin tissue of coal-burning-type of endemic arseniasis patients is over expressed.Abnormal expression of P14ARF and MDM2 may be one of the reasons lead to abnormal cell cycle control disorders and may play a role in the development of endemic arseniasis.

Objective To investigate the causations, management and prevention methods on the complications of hysteroscopic procedures. Methods Retrospective analysis of 36 cases with hysteroscopic complication, focusing on their characteristics and clinical management as well as prevention methods during the ten years from 1993 to 2004. Results Among 36 cases, 11 cases with uterine perforation and incomplete perforation, which happened during the complicated procedures, were treated by both laparoscopy and laparotomy. Five cases with heavy bleeding were encountered because of the deeply injury to the uterine wall and Foley catheter was inserted into uterine cavity and it stopped the bleeding successfully except in one case done by hysterectomy. Three cases with fluid overload syndrome were cured by using diuretic agent and saline infusion. There is no serious consequence in one case with air embolism due to prompt diagnosis and treatment. Four cases with postablation-sterilization syndrome were treated effectively by performing hysterectomy plus single or bilateral salpingectomy, dilating cervical canal as well as resecting adhesions. Twelve cases with adhesion inside uterine cavity followed hysteroscopy were also treated by dilating cervical canal, underwent adhesionlysis and hysterectomy. Conclusions The potential factors causing complications of hysteroscopy include complicated procedures inside uterine cavity, higher pressure of irrigation, deep injury of endometrium as well as incomplete removal of endometrium during hysteroscopic operations. It is the necessary measures to reduce the complications by performing laparoscopy or B ultrasound monitoring simultaneously, standardizing the procedure and strengthening postoperation management.

Objective To evaluate the expression of macrophage migration inhibitor factor (MiF) and cyclinD1 in pancreatic carcinoma and their relationships with clinical pathology characteristics. Methods The expression of MIF and eyclinD1 in 89 carcinoma and 5 normal pancreatic tissues was detected with immunohis-tochemistry methods, and the relationships among MIF and cyclinD1 expression and clinicopathological factors were studied. Results The overexpression of MIF and cyclinD1 was found in 88.8%, and 50. 6% of pancre-atic carcinoma tissues respectively. The overexpression of MIF had a significant correlation with Ⅰ,Ⅱ,Ⅲ,Ⅳ tumor stage (69. 2%, 94. 7%, 96. 4%, 100%, P <0.05), while the positive expression rate of cyclinD1 only had a significant correlation with tumor stages Ⅲ,Ⅳ (33. 3%, 68. 8%, P <0. 05). Both of the two proteins had a correlative tendency with pathological grade and lymph node metastasis. The different expression of MIF between pancreatic carcinoma with and without liver metastasis had no statistical significance, (100% ,85.9%, P >0. 05)while there was a statistically significant difference about cyclinD1 (66. 7% ,46. 5% ,P <0. 05). A significant positive correlation was also found between MIF and cyclinD1 (P < 0. 05). Conclusion The ex-pression of MIF and CyclinD1 was higher in pancreatic cancer tissues than in normal tissue, and they may be associated with the malignant stage, tumor differentiation, local lymph node and liver metastasis of this tumor.

Objective To detect anti-clinically amyopathic dermatomyositis (CADM)-140 antibody in patients with dermatomyositis (DM) or CADM,and to estimate its clinical correlation.Methods Serum samples were collected from 22 patients with DM,16 patients with CADM,46 patients with other connective tissue diseases complicated by interstitial lung disease(including 8 cases of polymyositis,15 cases of systemic lupus erythematosus,5 cases of systemic sclerosis,6 cases of Sj(o)gren syndrome,6 cases of mixed connective tissue disease,6 cases of idiopathic pulmonary fibrosis),and 5 normal human controls.Enzyme-linked immunosorbent assay (ELISA) was performed with the recombinant melanoma differentiation-associated gene 5(rMDA)as a substrate to measure the anti-CADM-140 antibody in these serum samples.Clinical manifestations were compared between patients with anti-CADM-140 antibody and those without.Results The anti-CADM-140antibody was found in 43.8% (7/16) of patients with CADM and 9.1%(2/22) of patients with DM(P<0.05),but absent in the patients with other connective tissue diseases and in the normal human controls.A significant incroase was observed in anti-CADM-140 antibody-positive patients with DM/CADM in the incidence of cutaneous ulceration and necrosis,interstitial lung disease and rapidly progressive interstitial lung disease (8/9 vs.6.9%,P<0.01;9/9 vs.48.3%,P<0.01;5/9 vs.0,P<0.05),serum lactate dehydrogenase level(328.3±104.2 vs 241.1±100.3 IU/L P<0.05),erythrocyte sedimentation rate(40.8±23.1 vs.22.5±16.8 mm/1 h,P<0.05),high resolution computed tomography score(122.9±54.8 vs.70.0±59.8,P<0.05)compared with anti-CADM-140 antibody-negative patients with DM/CADM.The ereatine kinase level was significantly lower(156.3±260.8 vs.1806.2±3737.1 IU/L P<0.05)in anti-CADM-140 antibody-positive patients with DM/CADM than in anti-CADM-140 antibody-negative patients with DM/CADM,while no significant difference was noted in the positivity rate of antinuclear antibodies or incidence of malignancies between the antibody-positive and-negative patients with DM/CADM.Conclusions Anti-CADM.140 antibody not only is useful for the diagnosis of interstitial lung disease in patients with DM/CADM,but also may serve as a serum marker for rapidly progressive interstitial lung disease.Monitoring of serum anti-CADM-140 antibody might help to predict the progression of interstitial lung disease in patients with DM/CADM.

OBJECTIVETo explore the protective effect of electroacupuncture (EA) pretreatment on ovarian function in rats with ovulation induction.

METHODSThirty SD female rats were numbered according to random number table. According to vaginal smear method, rats of estrus were divided into a normal group (10 rats) and cohabitated with male SD rats with the proportion of 1:1. With computer-generated random number, the remaining rats were divided into a model group and an EA group, 10 rats in each one. The model of superovulation was established with pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (HCG) in the model group and EA group. Before model establishment and cohabitation, rats in the EA group were treated with EA at "Guanyuan (CV 4)" and "Sanyinjiao (SP 6)", once for 15 min, for consecutive 7 days. Rats in the normal group and model group received no further treatment. The third day 23:00 pm after cohabitation, blood samples in three groups were collected to test the level of estradiol (E₂) and progesterone (P). After the rats were sacrificed, the HE staining method was applied to observe the morphological changes of ovarian tissue; the immunohistochemical method was applied to measure the expression of vascular endothelial growth factor (VEGF) and its receptor VEGFR-2; the real-time quantitative PCR technique was applied to measure the gene expression of VEGF and VEGFR-2.

RESULTSThe number of ovarian follicle in the EA group was higher than that in the model group and normal group (all P < 0.05); the ratio of corpus luteum size to ovarian size in the EA group was lower than that in the model group (P < 0.01). The ratio of plasma estradiol to progesterone in the EA group tended to be normal group (P < 0.05) and lower than that in the model group (P < 0.01). The protein expression of VEGF and VEGFR-2 in lutein granulosa cell and follicular fluid in the EA group was lower than that in the model group (P < 0.05); gene level of VEGF and VEGFR-2 in ovarian tissue in the EA group was lower than that in the model group (P < 0.05, P < 0.01).

CONCLUSIONEA pretreatment has certain protective effect on ovarian function in rats with ovulation induction, which is likely to be related to regulation of VEGF and its receptor.

OBJECTIVETo explore if reduced number of circulating endothelial progenitor cells (EPCs) is a risk factor for patients with coronary slow flow (CSF).

METHODSThirty patients with CSF and 30 age and gender matched control subjects with normal coronary angiography were included in the study. Mononuclear cells were isolated from peripheral blood by Ficoll density gradient centrifugation and plated on fibronectin-coated culture dishes. EPCs were characterized as adherent cells double positive for DiI-AcLDL-uptake and lectin-binding by converted fluorescence microscope (×200).

RESULTSSmoking, diabetes mellitus, hypertension and the levels of plasma lipoprotein profile were similar between the two groups (all P > 0.05). The number of EPCs was significantly lower in patients with CSF compared with control subjects (35.7 ± 5.9 vs.53.2 ± 5.9, P < 0.01). TIMI frame counts was correlated with circulating EPCs number (OR = 0.424, 95%CI 0.358 - 0.621, P < 0.01) and not associated with gender, age, smoking, diabetes mellitus, hypertension and the levels of plasma lipoprotein profile.

CONCLUSIONDecreased circulating EPCs is an independent risk factor for CSF.
