ABSTRACT
Objective:To observe the clinical features and prognosis of eyes with corneal suture-related infective endophthalmitis.Methods:A retrospective interventional case series. From January 2020 to December 2021, 5 patients (5 eyes) with corneal suture-related infectious endophthalmitis diagnosed by ophthalmic examination at Department of Ophthalmology of the Eye-ENT Hospital of Fudan University were included in the study. Among them, there were 3 males and 2 females; all had unilateral disease; the mean age was 30.80±21.98 years. Sutures of 4 cases were secondary to lens related surgery and of 1 case was secondary to penetrating keratoplasty. Average retention time of corneal suture was 20.00±7.41 months. Of the 5 eyes, corneal sutures were removed in 1 eye due to redness and eye pain in another hospital; 3 eyes were loosened of the sutures in the remaining 4 eyes. The patients were given standard treatment for infectious endophthalmitis, including systemic and local anti-infective therapy; corneal suture removal, intraocular injection, and vitrectomy (PPV). In PPV, it was decided whether to give silicone oil filling according to the situation. The follow-up time after treatment was 11.00±7.38 months. The best corrected visual acuity (BCVA), B-mode ultrasound and microbial culture results of the affected eye before and after surgery were observed and analyzed.Results:Infiltrates, ulcers, or abscesses surrounding the suture may be seen on the cornea of the affected eye. B-mode ultrasonography showed vitreous opacity, preretinal cords, and spherical wall edema in the entire segment of the affected eye. The results of vitreous humor culture were positive in 3 eyes, which were Streptococcus viridis, Staphylococcus hominis subspecies, Staphylococcus epidermidis. After treatment, all the intraocular infections in the affected eyes were successfully controlled, and there were no cases of enucleation of ocular contents or enucleation. Before treatment, the BCVA of the affected eye was from no light perception to counting fingers; after treatment, 2 eyes had BCVA> 0.3.Conclusions:Infiltration, ulcers or abscesses around the sutures can be seen in the cornea of corneal suture-related infective endophthalmitis patients, which are related to the long-term retention of the sutures in the eye. Most of the affected eyes have loose sutures when they go to the doctor; timely treatment can effectively control the infection, and some eyes have good visual prognosis.
ABSTRACT
Objective@#To investigate the protective effect of human umbilical cord mesenchymal stem cells (UCMSCs) on light-damaged retinal pigment epithelial (RPE) cells in vitro.@*Methods@#Human UCMSCs were cultured, and then identified by flow cytometry.Human RPE cells were isolated and cultured, and then the model of light-damaged RPE cells was prepared.The noncontact co-culture system of light-damaged RPE cells and UCMSCs was established by Transwell chamber.RPE cells were divided into normal control group, model control group and UCMSCs co-culture group.RPE cells in the normal control group were not treated.RPE cells in the model control group were treated with blue light to induce RPE cell damage.Co-culture system of light-damaged RPE cells and UCMSCs was established in the UCMSCs co-culture group.The proliferative ability of RPE cells was measured by methyl thiazolyl tetrazolium (MTT) assay at 24 hours and 48 hours after co-culture.ELISA kits were used to quantitatively measure the levels of pigment epithelium-derived factor (PEDF) and basic fibroblast growth factor (bFGF) in the culture supernatant at 48 hours after co-culture.And the photoreceptor outer segments (POS) phagocytosis assay of RPE cells was also conducted.@*Results@#UCMSCs displayed spindle-shaped morphology, positively expressed CD29, CD44, CD90 and CD105, while negatively expressed CD34 and CD45.RPE cells were polygonal in morphology and positive for the specific marker RPE65 protein.The proliferative ability(A value) of RPE cells in the three groups at different timepoints were significantly different (Fgroup=132.388, P=0.000; Ftime=231.440, P=0.000), the A values of RPE cells in model control group and UCMSCs co-culture group were significantly lower than that in the normal control group, the A value of RPE cells in UCMSCs co-culture group was significantly higher than that in the model control group, and the differences were statistically significant both at 24 hours and 48 hours after co-culture (all at P<0.01). POS phagocytosis test showed that there was a significant difference in the average number of POS particles phagocytized by RPE cells among the three groups(F=28.087, P=0.000). The average number of POS particles phagocytized by RPE cells in model control group was significantly lower than that in normal control group, and the average number of POS particles phagocytized by RPE cells in UCMSCs co-culture group was significantly more than that in model control group (all at P<0.01). ELISA showed that the concentrations of PEDF in RPE cell supernatant of normal control group, model control group and UCMSCs co-culture group were (18.8±1.9), (10.0±1.7) and (20.2±6.0)ng/ml, respectively.The concentrations of bFGF in RPE cell supernatant were (25.2±1.5), (26.3±3.6) and (61.9±14.3)pg/ml, respectively.There were significant differences in PEDF and bFGF concentrations among the three groups (F=8.654, P=0.008; F=23.698, P=0.000). The concentration of PEDF in the model control group was significantly lower than that in the normal control group, and the concentration of PEDF in the UCMSCs co-culture group was significantly higher than that in the model control group (all at P<0.01). The concentration of bFGF in UCMSCs co-culture group was significantly higher than that in the normal control group and model control group (all at P<0.01).@*Conclusions@#Cocultivation with UCMSCs can improve the proliferation ability and phagocytosis function of light-damaged RPE cells, and promote the secretion of PEDF by RPE cells.UCMSCs may protect RPE cells from light damage through paracrine secretion of bFGF.

ABSTRACT
BACKGROUND: In lumbar spondylolisthesis patients with severe osteoporosis, screw is easily loose and pul s out during reposition, or loss of reduction and internal fixation failure easily occur after repair. Therefore, it is very important to elevate the intensity of pedicle screw fixation during repair. At present, few studies concern application of bone cement screw enhancement technology in lumbar spondylolisthesis patients with osteoporosis. OBJECTIVE: To investigate the clinical value of augmented pedicle screw with polymethylmethacrylate for lumbar spondylolisthesis accompanied with osteoporosis. METHODS: From June 2009 to June 2011, 27 patients suffering from lumbar spondylolisthesis accompanied with osteoporosis were included in this retrospective study. These patients received augmented pedicle screw with polymethylmethacrylate. The levels of disability and pain were evaluated by Oswestry Disability Index and visual analog scale. The internal fixation and fusion were evaluated by radiological findings. Al complications were recorded. RESULTS AND CONCLUSION: Al cases were fol owed up for 15-37 months. Oswestry Disability Index and visual analog scale scores were significantly better in final fol ow-up than that pre-treatment (P < 0.05). Imaging results revealed that bone cement tightly connected to bone interface. The position of screw and bone cement was good. Symptomatic bone cement leakage was not found. No fixation failure was detected during final fol ow-up. Al patients achieved interbody fusion. These results suggested that polymethylmethacrylate bone cement could increase the gripping force of the pedicle screw in osteoporotic vertebral body. It is safe and effective to treat spondylolisthesis accompanied with osteoporosis with augmented pedicle screws. Satisfactory fixation stability and interbody fusion can be obtained.
ABSTRACT
BACKGROUND:There are so many studies about ovariectomized rats at present, but the research on the change rules of bone mass, bone turnover markers, estrogen levels and their correlation in different periods of ovariectomized rats is rarely reported. OBJECTIVE:To analyze the change rules of bone mass, bone turnover markers, estrogen level and their correlation in different periods of ovariectomized rats. METHODS: Thirty-four 3-month-old female Sprague Dawley rats were randomly divided into three groups: baseline group, ovariectomized group and sham operated group. At the beginning of the experiment, the rats in the baseline group were sacrificed, then rats in the ovariectomized group and sham operated group were executed at 4, 8, 12 weeks postoperative respectively. The bone mineral density, bone mass content, area of different zones of the L1-3 lumbar vertebrae and femurs were detected by dual-energy X-ray absorption method, and meanwhile the serum levels of type I procolagen amino-terminal pro-peptide, I colagen carboxy-terminal peptide and estrogen were determined by ELISA. At last, we analyzed the correlation between body mass, bone mineral densityin vitro, type I procolagen amino-terminal pro-peptide, I colagen carboxy-terminal peptide and estrogen levels and the age of ovariectomized rats. RESULTS AND CONCLUSION: (1) The bone mineral density and bone mass content of the lumbar vertebral and femurs in the ovariectomized group were significantly lower than those in the sham operated group and baseline group at the 4th week after operation (P < 0.05). The bone mineral density and bone mass content in the ovariectomized group were ameliorated obviously at the 8th and 12th weeks compared with those at the 4th week after operation (P < 0.05). The bone mass loss was highest in the L1 and intertrochanteric regions. (2) Serum levels of type I procolagen amino-terminal pro-peptide and I colagen carboxy-terminal peptide in the ovariectomized group were significantly higher than those in the baseline group and sham operated group at the 4th week after operation, but there was no difference at the 8th and 12th weeks. (3) The serum estrogen level in the ovariectomized group was prominently lower than that in the sham operated group and baseline group at the 8th and 12th weeks after operation (P < 0.01 at the 8th week,P < 0.05 at the 12th week). (4) The age was positively correlated with body mass and bone mineral density of the lumbar vertebrae and femursin vitro, while the serum levels of type I procolagen amino-terminal pro-peptide and I colagen carboxy-terminal peptide were negatively correlated with the bone mineral density of the lumbar vertebrae and femurs in vitro (P < 0.01). These results suggested that the bone mass of the lumbar vertebrae and femurs in ovariectomized rats was decreased rapidly firstly, and then rose slowly with time; the bone mass in the L1 and intertrochanteric regions lost seriously; the bone turnover markers showed a significant increase at the beginning of ovariectomy and reduced gradualy to normal condition, while the estrogen level was increased at the first month after ovariectomy and then decreased rapidly. In addition, the body mass, bone turnover markers and estrogen level were associated with the change of bone mass.

This study was aimed to investigate the expression and clinical significance of forkhead box protein O3a (FoxO3a) in the patients with acute myeloid leukemia (AML). Western blot was used to detect the FoxO3a protein expression in bone marrow samples from 44 newly diagnosed AML patients and 5 healthy donors. Additionally, 14 patients' samples were reevaluated when they got complete remission (CR). The results showed that FoxO3a expression (FoxO3a/β-actin 0.43 ± 0.19) in newly diagnosed AML patients was much higher than that in healthy donors (FoxO3a/β-actin 0.19 ± 0.06) (P < 0.001). The FoxO3a level was down-regulated when CR was got and there was not significant difference between patients in CR and healthy donors (P > 0.10). The correlation analysis showed that the level of FoxO3a expression positively correlated with the white blood cell count of AML patients at the time of diagnosis. Although FoxO3a expression did not positively correlate with the CR rate, the higher FoxO3a expression in AML patients showed a shorter remission duration. It is concluded that FoxO3a may be a oncoprotein in AML, and the high FoxO3a expression is associated with poor prognosis.

Dry eye is a most common external eye disease in clinic and it can cause ocular discomfort and visual disturbance. The conventional examinations for dry eye have some shortcomings, for example, high variability and insufficient association with symptoms. Recently, routine ophthalmic technologies play more extending roles in evaluation of dry eye, including corneal topography, wavefront aberrometer, optical coherence tomography (OCT) and confocal microscope. Corneal topography and wavefront aberrometer could be used to evaluate the stability of tear film and visual function. OCT could image tear meniscus directly, and confocal microscope could observe histopathology of ocular surface in vivo. The studies on ophthalmic technologies in dry eye make us deepen the understanding of pathophysiology of dry eye and also provide new diagnostic approaches.
ABSTRACT
Objective To investigate the correlation between the serum ghrelin levels and nutrition state in the patients with chronic obstructive pulmonary disease(COPD) ,as well as to explore the role of ghxelin in the nutri-tion metabolism. Methods Fifty-three COPD patients were observed, thirty-one of them were with malnutrition (group A), twenty-two COPD patients with normal nutrition status(group B), and twenty were healthy controls.Serum ghrelin, and nutritional parameters such as body mass index(BMI), ideal body weitht( % IBW), mid-upper arm cricumference(MAC), serum albumin(ALB), total lymphocyte counts(LYM) were determined. The correlation between ghrelin and nutritional parameters was analysed. Resuits The level of serum ghrelin in group A were sig-nificantly higher than those in group B and in healthy controls. And the serum ghrelin showed a negative correlation with BMI, % IBW, MAC, but there was no correlation between serum ghrelin level, ALB and LYM. Conclusion Ghrelin participated in the nutrition metabolism in patients with COPD, it would become much higher because of malnutrition in COPD.
