AIM: To compare and contrast different operation after cataract patients with refractive change rules. To analyze the patients with refractive stability after cataract surgery, and to provide a reference for cataract patients with clinical surgery after visual quality.
●METHODS: Retrospective study. A total of 126 cases (150 eyes) were selected from Jan. 2014 to Dec. 2015 in Changzhou First People′s Hospital of cataract extraction combined with foldable intraocular lens implantation for cataract patients as the research samples. According to the different operation for three groups, the first group of 42 patients ( 50 eyes ) underwent above 3 mm clear corneal incision;52 cases in group 2 (60 eyes) underwent temporal side 3 mm clear corneal incision. The third group, 32 cases (40 eyes) underwent 3 corner above the scleral tunnel incision. All the cases were measured at different time point in patients with naked eyes far visual acuity, best corrected visual acuity, spherical degree, the degree of astigmatism and astigmatic axial, comparative analysis of after cataract surgery in patients with refractive change regularity and stability of refraction.
●RESULTS: The uncorrected distance visual comparison within the group, and each time point after preoperative differences were significant ( P< 0. 01 ), and the early postoperative period after 1, 3mo significantly different (P<0. 05). Three groups of patients after surgery compared with preoperative uncorrected distance visual acuity improved significantly, and were stable after 1mo. Compare the best corrected distance vision within the group, and each time point after preoperative differences were significant (P<0. 01), postoperative 1wk and after 1, 3d significantly different (P<0. 05), after 1wk and after 1, 3mo was not significantly different ( P > 0. 05 ), three groups of patients were compared with the preoperative best corrected distance visual acuity were increased significantly, and were in stable after 1wk; relatively spherical degree within the array, after 1d and 3d was not significantly different (P>0. 05), hyperopia drift, after 1wk and 1, 3d was significantly different (P<0. 05), after 1wk and 1, 3mo was not significantly different ( P>0. 05 ). Three groups of patients′spherical degrees after 1wk were stabilized. Comparative degree of astigmatism within the array, postoperative compared with preoperative corneal astigmatism were increased 1d after surgery. Corneal astigmatism in each group reached the maximum, and then decreases 1wk and 1d after surgery, compared with postoperative 3d was significantly different ( P<0. 05 ). After 1wk and 1, 3mo was not significantly different ( P>0. 05 ) . Three groups of patients were compared with preoperative astigmatism were significantly increased, and in operation after 1wk were stabilized;astigmatic axis were three groups in the preoperative astigmatism against the rule, the first and third group after 1d, three Tianshun rule astigmatism proportional were increased, and then decreased. Group 2 the- rule astigmatism proportion, after 1wk, 1 and 3mo, the first and third group gradually reduced the proportion of cis regulatory astigmatism, and compared with preoperative increased, increasing the-rule astigmatism group 2 ratio, and increased compared with preoperative.
●CONCLUSION: Above 3 mm the transparent corneal incision, temporal clear corneal incision and above the scleral tunnel incision different surgical postoperative visual acuity are good. lt can be used as a routine surgical procedure in treatment of cataract;phacoemulsification in cataract patients with former majority against the rule astigmatism. After cataract surgery, early refractive state is a state of mild hyperopia and stabilized about 1wk, combined with clinical guide glasses.

· AlM:To investigate the effect of compound anisodine on fundus blood circulation after vitrectomy with face-down position.
· METHODS: Sixty patients ( 60 eyes ) with rhegmatogenous retinal detachment received vitrectomy with silicone oil tamponade operation, who were randomized divided into treatment group ( 30 eyes ) and control group ( 30 eyes ) .The patients in the treatment group received the subcutaneously injection of compound anisodine hydrobromide by the superficial temporal artery once daily for 14d since postoperative first day.Retinal microcirculation blood flow parameters were recorded with Heidelberg retinal flowmeter postoperative 1d, 1 and 2wk, and were compared between two groups.
·RESULTS: The blood flow parameters ( Vol, Flw, Vel) of control group postoperative 1 and 2wk were significantly less than those postoperative 1d.Otherwise the parameters of treatment postoperative 1 and 2wk were significantly more than those postoperative 1d. The parameters between two groups were significant different ( P<0.01) .
· CONCLUSlON: Facing down after vitrectomy with
silicone oil tamponade may reduce retinal blood supply, consequently lead to retinal ischemia; compound anisodine can effectively improve the retinal and choroidal microcirculation after vitrectomy with face-down posture, reduce retinal ischemia, and enhance the visual function.

BACKGROUND:The establishment of a good blood supply is a key mechanism for successful implantation of engineered tissues. OBJECTIVE:To observe the effect of basic fibroblast growth factor on the migration of human adipose-derived stem cells via implanting the human adipose-derived stem cells and sodium hyaluronate composite graft at the subcutaneous site of BALB/C mice, in order to explore an optimal scheme for soft tissue reconstruction. METHODS:Human adipose-derived stem cells were isolated from the adipose tissue of healthy cosmetic patients which received liposuction, and the cells were subcultured. Then 5×109/L passage 3 cellsuspension labeled by cm-dil was prepared. The working solution containing 2 mg/L basic fibroblast growth factor was prepared. Composite tissue al-lografts which were the mixtures of 0.25 mL sodium hyaluronate, 0.2 mL cellsuspension and 0.05 mL working solution or DMEM were implanted into the subcutaneous site of both sides of the mouse back. Specimens were taken at 6 weeks after operation and were evaluated histological y after hematoxylin-eosin and vascular immunofluorescent staining. RESULTS AND CONCLUSION:No necrosis, liquefaction, nodular tissue or gel remained in operated position. The hematoxylin-eosin staining showed the main components of the specimens were the adipose tissue and the loose connective tissue. The immunofluorescence staining showed the overlaps between the cm-dil fluorescence from human adipose-derived stem cells and the FITC fluorescence from the vascular endothelium in the experimental group were more than those in the control group (P<0.05). Basic fibroblast growth factor promotes the migration and the differentiation of human adipose-derived stem cells in the sodium hyaluronate scaffold into vascular endothelium.

BACKGROUND:Expanded polytetrafluoroethylene is a kind of porous polymer materials which is commonly used as clinical implants, and it has good biocompatibility, and is not easy to deformation or metamorphism. There is no existence of inflammation absorption reaction, and it al ows the cel migration and tissue ingrowth.
OBJECTIVE:To study the biocompatibility of expanded polytetrafluoroethylene scaffold and human adipose-derived stem cel s.
METHODS:The passage 4 human adipose-derived stem cel s were co-cultured with expanded polytetrafluoroethylene scaffold in vitro. The morphology and function of cel s adhered to the scaffold were observed by inverted phase contrast microscope, and cel adhesive rates and proliferation rates were also calculated by MTT assay.
RESULTS AND CONCLUSION:The inoculated cel s were round and bright, distributed on the surface of scaffolds uniformly, with good cel viability. After 3 hours a large number of adherent cel s were observed from the micrograph;after 24 hours there were a smal amount of short-spindle adipose-derived stem cel s. After cultured for 3 days, the short fusiform or polygon cel s could be seen clearly. After cultured for 7 days, the number of cel s increased significantly, few cel s fel off from the scaffold, and cel adhesion rate was up to an average of 95.7%. Meanwhile, the cel s revealed normal splitting proliferation rate. These findings indicate that human adipose-derived stem cel s are able to attach, grow and proliferate wel on the scaffold. Expanded polytetrafluoroethylene reveals excel ent cel ular compatibility and can be used as a vehicle for adipose tissue engineering.

Objective:To observe the effect of metformin on the expression of SIRT1 and UCP2 in rat liver of type 2 diabetes mellitus (T2DM) with nonalcoholic fatty liver disease (NAFLD), and discuss the pathogenesis of T2DM with NAFLD, and the treatment with and possible mechanism of metformin.Methods:Thirty-six male SD rats were randomly divided into a normal control group (group NC, n=12), a T2DM with NAFLD group (group MC, n=12), and a metformin group (group A, n=12). We established the model of T2DM with NAFLD rats by feeding high-fat and high-sugar diet and injecting STZ. After the success establishment of the model, the metformin group was given metformin 300 mg/(kg.d) for 8 weeks. At the end of the experiment, we measured FBG, ALT, AST, TC, TG, HDL-C, LDL-C, VLDL, FFAs, FINs and HOMA-IR respectively in group NC, MC and A. We observed the change of liver tissue pathology by HE, determined the expression of SIRT1 and UCP2 in rat liver by immunohistochemical method and real-time quantitative method. Results:FBG, ALT, AST, TC, TG, LDL-C, VLDL, FFAs, FINs and HOMA-IR were higher in group MC than in group NC (P<0.05), while HDL-C was obviously lower in group MC than in group NC (P<0.05). After the metformin treatment, the serum parameters in the rats had improved in group NC compared with in group MC (P<0.05). On immunohistochemical staining and mRNA level, the expression of SIRT1 was obviously lower in group MC than in group NC (P<0.05), and the expression of UCP2 was obviously higher in group MC than in group NC (P<0.05). After the metformin treatment, the expression of SIRT1 was higher than in group MC (P<0.05), and the expression of UCP2 was lower than in group MC (P<0.05). There was negative correlation between the expression of SIRT1 and UCP2 (r=-0.61, P<0.01).
Conclusion:The expression of SIRT1 is low and the expression of UCP2 is high in rat liver of T2DM with NAFLD. Metformin can increase the expression of SIRT1 and reduce the expression of UCP2, with negative correlation between the expression of SIRT1 and UCP2.

Objective To identify the outcome of pregnancy and the alteration of renal function in women with nephrotic syndrome. Methods From 2003 to 2007, 59 pregnant women with nephrotic syndrome in our hospital were enrolled in the study. Their clinical data were retrospectively analyzed, including the time of kidney disease onset, 24-hour proteinuria, serum albumin, serum creatinine, blood uric acid, blood pressure, fetal survival, fetal mortality, rate of premature delivery, birth weight of the newborn, and proteinuria, renal function, blood pressure of the patients during their postpartum follow-up. Logistic regression analysis was used to identify the risk factors influencing the outcome of the patients and the newborns. Results The average gestational week was (20.35±9.40) weeks when proteinuria was detected in these pregnant women. The 24-hour proteinuria ranged from 3.5 to 15 g/24 h (median 5.1 g/24 h). The serum albumin was between 10 and 28 g/L (median 22.5 g/L). The serum creatinine was between 32 and 825 μmol/L (median 84 μmol/L) and the serum uric acid ranged from 196 to 793 μmol/L (median 385.5 μmol/L). Pregnancy-induced hypertension syndrome occurred in 75% of the patients, among whom 55.5% suffered from preeclampsia. Forty-three (72.9%) newborns survived , among whom 76.7% (33/43) were premature births and 62.8% (27/43) were low birth weight infants. 50% of the pregnant women still had nephrotic syndrome after delivery. 75% of 24 patients with pre-existing chronic glomerulonephritis had increased proteinuria during pregnancy. Among the 38 patients with renal insufficiency, 36.8% had poorer renal function after delivery. 23.7% of the patients progressed into end stage renal failure after delivery, 80% of whom had serum creatinine ≥ 265 μmol/L. 89% of the patients had persistent hypertension after childbirth. The Logistic regression analysis indicated hyperuricemia during pregnancy (P=0.018, OR=1.012) and the increase of serum creatinine (P=0.039, OR=1.005) were risk factors of renal failure in pregnant women after delivery. Hyperuricemia (P=0.012, OR=1.006)was the risk factor of fetal death. Conclusions Pregnancy with nephrotic syndrome leads to a low fetal survival. Hyperuricemia is the most important risk factor of the poor outcome of pregnant women and newborn.

Background Research demonstrated that alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid GluR2 (AMPA-GluR2) is associated with amblyopia.It has been shown that levodopa and cytidine diphosphate choline can improve visual function of amblyopic children,but the mechanism is unclear.Objective This study was to explore the possible effects of levodopa and cytidine diphosphate choline on amblyopia.Methods Monocular deprivation (MD) animal models were created in 60 2-week-old SD rats by monolateral eyelid suturing and observed for 31 days and reared in natural light together with 15 other matched normal healthy SD rats.The models were randomly divided into the MD group,levodopa group,cytidine diphosphate choline group and normal saline control group,with 15 rats for each group.40 mg/kg of levodopa,80 mg/kg of cytidine diphosphate choline,I ml normal saline were given to the rats,respectively,for 28 consecutive days.Expressions of the AMPA-CluR2 protein and AMPA-CluR2 mRNA in the rat visual cortex were detected by immunohistochemistry,Western blot and real-time fluorescence quantitative PCR.Use of the animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The expression values of the AMPA-GluR2 protein (AMPA-GluR2/β-actin) and AMPA-GluR2 mRNA (2-△△Ct) were significantly lower in the MD group than those of the normal control group (protein:0.32 ± 0.02 vs.0.64 ± 0.05,t =13.287,P＜0.05 ;mRNA:0.30±0.01 vs.0.84±0.03,t=38.184,P＜0.05).Those in the levodopa group were significantly increased in comparison with the normal saline solution group (protein:0.59 ±0.04 vs.0.33 ±0.03,t =11.628,P＜0.05 ; mRNA:0.71±0.06 vs.0.33 ±0.02,t =13.435,P＜0.05).The expression values of the AMPA-GluR2 protein and AMPA-GluR2 mRNA were significantly increased in the cytidine diphosphate choline group compared with the normal saline solution group (protein:0.52 ± 0.04 vs.0.33 ± 0.03,t =8.497,P ＜ 0.05 ; mRNA:0.48± 0.04 vs.0.33 ± 0.02,t =7.500,P＜0.05).Conclusions AMPA-GluR2 is associated with the plasticity of visual development.Levodopa and cytidine diphosphate choline may improve visual function by down-regulating the expression of AMPA-GluR2 in the visual cortex.
