Objective To observe the baseline characteristics and visual outcomes after two years follow-up of exudative age-related macular degeneration (AMD) patients treated with ranibizumb. Methods Forty-four eyes of 44 patients with exudative AMD were enrolled into this retrospective study, 19 were men and 25 were women. The mean age was 78 years (range 64–92 years). All patients were underwent best corrected visual acuity (BCVA, Early Treatment of Diabetic Retinopathy Study), fundus color photography, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optical coherence tomography (OCT). The mean BCVA was (50.36±14.43) letters, the mean central foveal thickness (CFT) was (291.95± 82.19)μm, and the fluorescence leakage area of choroidal neovascularization (CNV) was (7.61±5.84) mm2. All patients received three initial intravitreous injection of ranibizumb (IVR) and were retreated with monthly IVR when needed. The mean follow up time was 25.6 months (range 24–29 months). On 1, 2, 3, 6, 12, 18 and 24 months after treatment, BCVA and OCT were repeated. On 3, 6, 12, 18 and 24 months after treatment, FFA and ICGA were repeated. The change of BCVA, CFT and fluorescence leakage area of CNV were observed. The association of baseline characteristics and two year visual outcomes were analyzed. Results On 1, 2, 3, 6, 12, 18 and 24 months after treatment, the BCVA were improved significantly (t=?1.89,?3.51,?4.61,?4.04,?5.77,?4.69;P<0.05), the CFT were decreased significantly (t=1.51, 2.30, 3.40, 3.28, 3.54, 3.88, 3.73;P<0.05). On 3, 6, 12, 18 and 24 months after treatment, the fluorescence leakage area of CNV were reduced significantly (t=2.12, 2.90, 3.51, 4.12, 4.06;P<0.05). The lower baseline BCVA, the more improved after treatment. The BCVA improvement degree has a negative relationship with baseline BCVA and fluorescence leakage area of CNV (r=0.505,?0.550;P<0.05), but no correlation with baseline CFT (r=0.210, P>0.05). Conclusion Two year visual outcomes of exudative AMD patients treated with ranibizumb is negative correlated with baseline BCVA and fluorescence leakage area of CNV, but not correlated with baseline CFT.

Objective To compare the short-term efficacy of conbercept and ranibizumab for macular edema in central retinal vein occlusion (CRVO)and explore the relationship between the integrity of ellipsoidal zone and visual acuity.Methods Forty-four eyes of 44 patients with macular edema in CRVO were enrolled into this retrospective and comparative study.There were 15 eyes of 15 males,29 eyes of 29 females;age ranged from 49-61 years old,with an average age of (54.65±3.10) years.All patients were examined with best-corrected visual acuity (BCVA),intraocular pressure (IOP),slit lamp,fundus photograph,fundus fluorescein angiography (FFA),optical coherence tomography(OCT).BCVA were examined with interactional visual chart and recorded with logarithm of the minimum angle of resolution acuity.Twenty-three eyes were intravitreal injected with conbercept 0.5 mg (group A) and 21 eyes were intravitreal injected with ranibizumab 0.5 mg (group B).There was no statistical difference of age (t =-1.41),gender (x2 =0.55),the percentage of hypertension patients (x2 =0.27),average BCVA (t =-2.06),IOP (t=-2.52),central macular thickness (CMT) (t=-1.96),number of different integrity of ellipsoidal zone patients (x2 =1.00) and number of different types of macular edema patients (x2 =1.03)among the two groups (P＞0.05).The change in BCV.A.and CMT at 3,6 months between the two groups were compared.The relationship between BCVA at 6 months and BCVA,CMT at baseline were explored.The relationship between three groups of ellipsoidal zone and BCVA at baseline were evaluated.The change of BCVA after treatment between the three groups of ellipsoidal zone were Compared.The number of intravitreal injections between two groups was compared.Results During the 3,6 months after treatment,the mean BCVA were all improved with statistically difference in group A 0=5.13,7.39;P＜0.05) and group B (t=6.60,11.52;P＜0.05).There was no significant difference of BCVA at 3,6 moths between group A and group B (t=-0.99,-0.40;P＞0.05).During the 3,6 months after treatment,the mean CMT were all decreased with statistically difference in group A (t=11.58,i5.96;P＜0.05) and group B (t=18.77,35.16;P＜0.05).There was no significant difference of CMT at 3,6 months between group A and group B (t=-1.52,-1.63;P＞0.05).In both groups,BCVA at 6 months was related to BCVA at baseline (r=0.44,0.62;P＜0.05),but not related to CMT at baseline (r=0.19,0.01;P＞0.05).In the two groups,BCVA at baseline was related to the integrity of ellipsoidal zone (r=0.97,0.70;P＜0.05).There was statistical difference of the number of intravitreal injections in the two groups (t =-6.88,P＜0.05).There was no systemic or ocular serious side effects during the follow up.Conclusions Comparing to ranibizumab,conbercept has the same effective to the treatment of macular edema in CRVO,but the number of intravitreal injections is less.The integrity of ellipsoidal zone is related to BCVA.

Objective To analyze the clinical outcomes of patients treated with in vitro fertilization and embryo transfer (IVF-ET) and influence factors of pregnancy rate. Methods We retrospectively analyzed the clinical data of 12 491 cycles, including 6832 fresh IVF/intracytoplast single sperm injection (ICSI) cycles and 5659 frozen embryo transfer (FET) cycles from 2005 to 2007. Results The clinical pregnancy rate per cycle was 32. 99% (2254/6832)in fresh embryo transfer program, and the live birth rate was 25.75% (1394/5413); the early pregnant loss rate was 9. 36% (211/2254), and the prenatal defect rate was 1.45% (25/1722). Through analysis of these patients' basic data, we found that the patients' age, causes for infertility, egg retrieval and cycle number affected the pregnancy rate. Using logistic regression method, we found that patients′ age was the most important factor affecting pregnancy outcome. In FET cycles, the clinical pregnancy rate was 38.08% (2155/5659), significantly higher than fresh embryo transfer cycles. Conclusions IVF-ET treatment is a safe and effective method for infertility couples. However, the female age and poor ovarian response are the main factors affecting pregnancy rate. Thawed embryo transfer can increase the accumulated pregnancy rate effectively.

The nanocomposites of poly-diallyldimethylammonium chloride (PDADMAC) and CdTe quantum dots (QDs) (i.e.QDs-PDADMAC nanocomposites) have been prepared based on electrostatic interaction and their fluorescence stability in aqueous solution has been investigated. MTT method(3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazoliumbromide method) was used to study their cytotoxicity and A549 lung cancer cell as a model cell was also used to evaluate their cellular imaging.It was shown that the fluorescence stability of QDs-PDADMAC nanocomposites was much better than that of bare QDs both in aqueous solution and cell.Meanwhile,QDs-PDADMAC nanocomposites display very low cytotoxicity in the low concentrations and better staining ability compared with QDs.QDs-PDADMAC nanocomposites will have great advantage on the cell analysis detection and imaging.

Objective To study and to optimize culture conditions of islet-like cells induced in vitro from fetus bone marrow(BM) mesenchymal stem cells(MSCs).Methods BM was obtained from miscarried human fetus.The MSCs between three to eight passages were used to differentiate into islet-like clusters-through three stages of culture supplemented with 2mercaptoethanol,epidermal growth factor(EGF),basic fibroblast growth factor(bFGF),B_(27) and nicotinamide.Results The 2nd stage cells expressed nestin and/or panceatic and duod-enal homeobox 1(PDX-1),and the 3rd stage cells formed islet-like clusters expressing insulin and glucagon together with positive dithizone staining.Specific insulin secretion could be detected(81.3?23.6?u /ml) from differentiated MSCs which have the capacity to respond to different glucose concentrations.Conclusion Fetal bone marrow MSCs can be differentiated into pancreatic islet-like clusters,and 20mmol/L nicotinamide could be the optimal concentration in culture.

Objective To investigate the effects of subthreshold micropulse yellow laser (577 nm) on vascular endothelial growth factor (VEGF),nerve growth factor (NGF) and Chemerin expressions in retina of early stage diabetic rats.Methods A total of 40 Brown Norway rats were treated with streptozocin (65 mg · kg-1) to establish the diabetic model.20 diabetic BN rats' right eyes were received subthreshold micropulse yellow laser (577 run) therapy after 2 weeks.The left eyes were used as control group.At 3 days,7 days,14 days,28 days after laser therapy,5 BN rats were randomly chosen to perform RT-PCR and Weston-blot.The expressions of mRNA and protein of VEGF,NGF and Chemerin were analyzed.Results The expression of VEGF mRNA and protein increased in control group at 3 days,7 days,14 days and 28 days (all P ＜ 0.05).Compared with the control group,VEGF mRNA and protein decreased in the subthreshold micropulse yellow laser (577 nm) group (all P ＜ 0.05).The expression of NGF mRNA and protein decreased in the control group at 3 days,7 days,14 days and 28 days (all P ＜ 0.05),however,the difference was not statistically significant between 3 days and 7 days(P ＞0.05).Compared with control group,NGF mRNA and protein increased in the subthreshold micropulse yellow laser (577 nm) group (all P ＜ 0.05),with maximum expression at 14 days.The expression of chemerin mRNA and protein increased at 3 days,7 days,14 days and 28 days in the control group (all P ＜0.05).Compared with the control group,chemerin mRNA and protein decreased in the subthreshold micropulse yellow laser (577 urn) group (all P ＜ 0.05).Conclusion Subthreshold micropulse yellow laser (577 urn) can suppress VEGF,Chemerin expression and upregulate NGF expression in early stage diabetic rats.

Objective To investigate the expression levels of serum vascular endothelial growth factor (VEGF), lactate dehydrogenase (LDH), sugar chain antigen-125 (CA125), and β2-microglobulin (β2-MG) in peripheral blood of patients with diffuse large B-cell lymphoma (DLBCL) and their clinical significances. Methods Thirty cases of DLBCL diagnosed by pathology in Fenyang Hospital of Shanxi Province and Shanxi Dayi Hospital from December 2011 to June 2013, 20 cases of healthy individuals as normal control group were enrolled. The levels of serum VEGF, CA125 and β2-MG in peripheral blood were detected by enzyme-linked immunosorbent assay (ELISA). Serum levels of LDH were detected by the rate method for measuring. Results The expression levels of VEGF, LDH, CA125 and β2-MG in DLBCL patients were higher than those in the healthy control group [(368±194) vs. (156±48) pg/ml, t=5.718, P=0.000;(487±252) vs. (177±32) U/L, t= 6.658, P= 0.000; (58 ±16) vs. (19 ±10) U/ml, t= 9.701, P= 0.000; (3.1 ±1.5) vs. (1.6 ±0.3 ) mg/L, t=5.612, P=0.000]. The expression levels of serum VEGF and LDH in DLBCL patients with stage Ⅲ-Ⅳ were significantly higher than those in patients with stage Ⅰ-Ⅱ [(506±165) vs. (275±154) pg/ml, t= 3.896, P=0.000; (886 ±433) vs. (220 ±86) U/L, t= 5.244, P= 0.000]. The expression levels of VEGF and LDH in DLBCL patients with bone marrow infiltration were higher than those in patients without bone marrow infiltration [(505±201) vs. (299±152) pg/ml, t= 3.148, P= 0.004; (798±463) vs. (331±166) U/L, t= 3.113, P=0.005]. There were no significant differences in the expression levels of VEGF and LDH between patients with A symptoms and B symptoms (all P>0.05). The serum levels of CA125 and β2-MG in the observation group had not relationship with clinical stage, the presence of A or B symptoms and the presence of bone marrow infiltration (all P> 0.05). The high expression of VEGF had correlation with the high expression of LDH in the observation group (r=0.458, P<0.05). Conclusions The expression levels of VEGF, LDH, CA125 andβ2-MG in DLBCL patients before treatment are high, and the high expression levels of VEGF and LDH are closely related to the clinical stage, disease progression and invasion. Combined detection of VEGF and LDH may be a useful predictor of bone marrow involvement in patients with DLBCL.

Objective:To evaluate the clinical efficacy of neck pricking combined with oral pricking in the treatment of dysphagia after stroke.Methods:Seventy-four patients with post-stroke dysphagia who met the inclusion criteria were randomly divided into the treatment group (acupuncture + rehabilitation training group) and the control group (rehabilitation training group) according to random number table method, 37 cases for each group. Both groups of patients were given conventional drug therapy and rehabilitation of Chinese and Western medicine. On this basis, the control group used swallowing rehabilitation training. The treatment group used acupuncture combined with neck pricking and oral pricking based on swallowing rehabilitation training. Both groups were treated for 3 weeks. Before and after the treatment, three different traits of sputum (liquid, mushy and paste) videofluoroscopic swallowing study (VFSS) were observed for each patient, and the swallowing conditions were observed. The primary outcome measures were the oral swallowing scale score, the pharyngeal swallowing scale score, the Rosenbek infiltration/aspiration scale score, and the standard swallowing function rating scale (SSA). The improvement in swallowing function and aspiration was compared between the two groups.Results:After treatment, the SSA score of the treatment group (25.05 ± 5.27 vs. 28.66 ± 5.33, t=2.884) was lower than that of the control group ( P<0.05). Compared with the same group before treatment, treatment group and control group of oral stage VFSS liquid ( t=5.199, 5.413), mushy ( t=4.761, 4.824) and pasty ( t=5.295, 4.428) scores, throat stage liquid ( t=4.986, 3.919), mushy ( t=4.789, 4.170) and pasty ( t=4.136, 3.673) scores were increased ( P<0.01), but there was no statistically significant difference between the groups ( P>0.05). After treatment, Rosenbek's leakage-aspiration degree classification was significantly reduced ( Z values were 4.224, 2.956, all Ps<0.01), but there was no statistically significant difference between the groups ( P>0.05). The total effective rate was 89.2% (33/37) in the treatment group and 74.3% (26/35) in the control group. There was no statistically significant difference between the two groups ( Z=1.125, P=0.261). Conclusions:Neck pricking combined with oral pricking and rehabilitation training for stroke dysphagia is better than simple rehabilitation training, and could significantly improve swallowing-feeding function, which could be promoted in clinical rehabilitation.
