AIM: To evaluate the clinical effect and the rotational stability of AcrySof Toric intraocular lens ( IOL ) implantation to correct preexisting corneal astigmatism in cataract surgery.
METHODS: Twenty-three patients ( 28 eyes ) were enrolled from the department of ophthalmology in the first Affiliated Hospital of Nanjing Medical University. All patients underwent similar phacoemulsification procedure combined with AcrySof Toric IOL implantation from June 2012 to December 2013. The uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA ) , anticipated residual astigmatism, postoperative residual astigmatism, and Toric IOL axis were detected and measured.
RESULTS:Three months after operation, the UCVA of all eyes were 0. 75±0. 16 and the BCVA were 0. 84±0. 15, there was no significant difference between UCVA and BCVA ( t = 1. 036, P>0. 05 ). The anticipated residual astigmatism was ( 0. 28±0. 12 ) D. The actual residual astigmatism after 3mo of the operation was (0. 42±0. 17) D. There was no significant difference between anticipated and actual residual astigmatism (t=1. 259, P>0. 05). The mean axis rotation of Toric IOL was 3. 02o±1.56o (0o-7o) after 1d of operation and 3. 28o±1. 85o (0o-7o) after 3mo. Among all the eyes, 25 eyes ( 89%) rotated <5o, in 3 eyes (11%) rotated 5o-7o.
CONCLUSION: The AcrySof Toric IOL implantation shows good effectiveness, predictability and stability in correcting pre-existing astigmatism in cataract patients.

Objective:To assess the efficacy and safety of oncoplastic breast-conserving surgery (OBCS) in the treatment of early breast cancer. Methods:The clinicopathological data of breast cancer patients who were treated with OBCS (67 cases) and standard breast-conserving surgery (SBCS;117 cases) in Affiliated Cancer Hospital of Guangxi Medical University were retrospectively analyzed. Postop-erative complication, specimen weight, margins, and surgery re-excision rate between the two groups were compared. Results:Sero-ma (14.9%versus 48.7%, P<0.001), hematoma (4.5%versus 14.5%, P=0.035), and poor wound healing (3.0%versus 11.9%, P=0.036) were more common in the SBCS group than in the OBCS group. The patient satisfaction in the OBCS group was statistically higher than in the SBCS group (P<0.05). Compared with standard surgery, oncoplastic techniques can be employed for significantly larger tumors (25.04 mm versus 21.14 mm, P<0.001). OBCS resulted in higher mean specimen weights (92.24 g versus 57.44 g, P<0.001), wider clear nearest margins (12.04 mm versus 9.58 mm, P<0.001), and wider furthest margins (24.16 mm versus 15.24 mm, P<0.001). No statisti-cal increase was observed in further surgery re-excision of margins. Conclusion:OBCS is more successful than standard wide local exci-sion in treating larger tumors and obtaining wider radial margins. Oncoplastic approach showed no increase in postoperative complica-tion rate. The postoperative complication was excellent. OBCS is a safe and effective procedure for early breast cancer.

Objective To investigate the impact of desmoglein 3 (Dsg3) on the proliferation of peripheral T lymphocytes from patients with pemphigus vulgaris (PV).Methods Peripheral blood mononuclear cells (PBMCs) were obtained from 12 patients with PV and 22 normal human controls,cultured with or without the presence of Dsg3 or phytohemagglutinin for 3 days.Flow cytometry was performed to detect the changes of T-lymphocyte subsets in PBMCs stimulated with Dsg3 and proliferation of T-lymphocytes.Results In patients with PV,the percentage of Th2 and Th1 cells was 12.17%±5.32% and 4.08%±1.50%,respectively in Dsg3stimulated PBMCs,9.84%±5.41% and 3.91%±1.38%,respectively in non-stimulated PBMCs.Increased percentage of Th2 cells was observed in Dsg3-stimulated and non-stimulated PBMCs from patients with PV compared with those from normal human controls (both P<0.05).After stimulation with Dsg3,there was a significant proliferation of T cells from patients,and the proliferation rate of CD4+T cells was 4.65%±3.28%,which was significantly higher than that from normal controls(P<0.05).Conclusion Dsg3 can induce the specific proliferation of CD4+T cells,especially Th2 type CD+4 T cells,from patients with PV.

[ ABSTRACT] AIM:In order to observe the myocardial differentiation capacity of the dedifferentiated fat ( DFAT) cells treated with vitamin C in vitro.METHODS: DFAT cells were dedifferentiated from the mature rat adipocytes with ceiling adherent culture.The DFAT cells of passage 3 were used in the study.Vitamin C and/or neonatal rat heart tissue lysate were added into the culture medium to induce myocardial differentiation for 3 weeks.The cell morphology was ob-served under microscope.The myocardial-specific markers, such as cTnT, GATA-4 and NKx2.5, were examined by the methods of immunofluorescence, PCR and Western blot.RESULTS:Mature rat adipocytes dedifferentiated into fibroblast-like DFAT cells after ceiling adherent culture.The DFAT cells spontaneously differentiated into cardiomyocyte-like cells under normal culture condition with a low incidence.After treated with neonatal rat heart cell lysate, the DFAT cells be-came cardiomyocyte-like cells that had bigger size, longer shape and myotubule-structure.The expression of cTnT, GATA-4 and NKx2.5 was remarkably increased at both mRNA and protein levels as compared with the normal cultured DFAT cells.The expression of cTnT, GATA-4 and NKx2.5 was further increased in DFAT cells after treating with vitamin C.No spontaneous beating cell was observed.CONCLUSION:Vitamin C enhances the differentiation of DFAT cells into cardio-myocyte-like cells.

Objective To evaluate clinical value of ultrasound contrast agent the sulfur hexafluoride micro-bubble in the treatment of T2WI high signal uterine fibroids with high intensity focused ultrasound (HIFU).Methods A total of 36 patients with T2WI high signal uterine fibroids were randomly divided into experimental group and control group.Eighteen patients in experimental group received HIFU treatment with sulfur hexafluoride micro-bubble before,during and after the operation while another eighteen in control group received HIFU treatment with sulfur hexafluoride micro-bubble only after the operation.We recorded operation time (min),changing time of massive gray (s),irradiation time (s),therapeutic dose (J),incidence of complications and ablation rate (％).Results Operation time,changing time of massive gray,irradiation time,and therapeutic dose in experimental group were (101.51±43.02) min,(856.42±451.14) s,(1077.37±546.23) s,and (496581.81 ± 267192.31) J,respectively while those in control group were (261.34 ± 85.53) min,(1 833.32 ± 642.67) s,(1 890.21 ± 1 268.43) s,and (784 608.31 ± 357 621.45) J,respectively.Significant differences were found among those parameters between the two groups (P ＜0.05).Tumor ablation rate in experimental group was 83.3％ while that in control group was 55.5％,which was of significant difference between the two groups (P＜0.05).One case of muscular stiffness was found in experimental group while one case of second-degree burn and two cases of muscular stiffness were found in the control group.The incidence of complications was 1/18 (5.5％).No severe complication like bowel perforation or bladder perforation was found in the two groups.Conclusion The effect of ultrasound contrast agent sulfur hexafluoride micro-bubble can shorten operation time,improve tumor ablation rate and reduce complications and it can play a guiding role in clinical work.

BACKGROUND:The position of median and radial nerves corresponding to elbow is usual y estimated by macroscopical measurements, but there are big data errors when the elbow is bent. OBJECTIVE:To measure and analyze the impacts of elbows in different positions on median and radial nerves under X-ray. METHODS:Ten fresh frozen upper limb specimens were selected. The distance of median and radial nerves to the osseous marks inside the elbow was measured when the elbow was in extension, extension-half pronation, bent at flexion 90 degrees and bent at 90 degrees with the injection of normal saline into the joint capsule, respectively. RESULTS AND CONCLUSION:The positions of median and radial nerves were not influenced when the elbow was in extension or in extension-half pronation (P>0.05). The distance of median and radial nerves to the osseous mark of the elbow was significantly lengthened when the elbow was moved from from extension to was bent at 90 degrees (P<0.05). The intra-articular injection of normal saline when the elbow flexion 90 degrees significantly elongated the distance of median and radial nerves to the osseous mark of elbow (P<0.05). These results suggest that the elbow in different positions can induce the displacement of median and radial nerves. In addition, the distance between median, radial nerves and the osseous marks of the elbow is obviously lengthened when the elbow is in flexion with intra-articular injection of normal saline.

To improve the yield of industrial fermentation, a method based on near infrared spectroscopy was presented to predict the growth of yeast.The spectral data of fermentation sample were measured by Fourier-transform near-infrared (FT-NIR) spectrometer in the process of yeast culture.Each spectrum was acquired over the range of 10000-4000 cm1.Meanwhile, the optical density (OD) of fermentation sample was determined with photoelectric turbidity method.After that, a method based on competitive adaptive reweighted sampling (CARS) was used to select characteristic wavelength variables of NIR data, and then extreme learning machine (ELM) algorithm was employed to develop the categorization model about the four growth processes of yeast.Experimental result showed that, only 30 characteristic wavelength variables of NIR data were selected by CRAS algorithms, and the prediction accuracies of training set and test set of the CARS-ELM model were 98.68% and 97.37%, respectively.The research showed that the near infrared spectrum analysis technology was feasible to predict the growth process of yeast.
