Intra-arterial chemotherapy (IAC) is an interventional treatment for retinoblastoma (RB) which infuses the chemotherapeutic agents through ophthalmic artery using microcatheters to control the tumor. Compared with systemic chemotherapy, IAC could significantly increase the globe salvage of advanced and recurrent RB without serious adverse event. Due to the absence of systemic absorption after IAC, no longer effectively kill tumor cell, which have potential danger to leads to inadequate elimination extraocular tumor cells. The most common systemic complications following IAC is myelosuppression; local ocular toxicities include eyelid edema, delacrimation, blepharoptosis, vitreous hemorrhage, retinal artery obstruction. During the last 10 years of clinical application, IAC become one of first-line treatment for intraocular RB. However, at present, there is still a lack of randomized controlled multicenter studies and long-term follow up of IAC.
ObjectiveTo analyze the correlation of thrombopoietin (TPO) and anti-TPO antibody with thrombocytopenia in patients with primary Sjögren syndrome (PSS). MethodsWe included in our study 40 PSS patients with thrombocytopenia (group A), 22 PSS patients who once had thrombocytopenia and returned to normal (group B), 40 PSS patients with normal platelet counts (group C) and 40 healthy controls (group D) between September 2013 and October 2014. Anti-TPO antibody was detected by indirect enzyme-linked immunosorbent assay (ELISA), and serum TPO levels were measured by ELISA. We analyzed the relationship between the assay results and the clinical manifestations and parameters. ResultsThe serum TPO levels in groups A, B, and C were (129.74±17.47) , (330.23±18.07) and (364.19±12.25) pg/mL, respectively, and they were significantly higher than that in group D [(54.04±10.71) pg/mL] (P ＜ 0.05) . The serum level of TPO was positively correlated with CRP and IgA (rs=0.224, P=0.039; rs=0.239, P=0.033) , and was negatively correlated with C4 level (rs=?0.220, P=0.041) , but it was not significantly correlated with platelet count, erythrocyte sedimentation rate, the level of antiphospholipid antibodies and the titer of antinuclear antibodies (P ＞ 0.05) . The positive rate of PSS patients was 20.59% (21/102) and the rate in groups A, B, and C was respectively 17.5% (7/40) , 22.72% (5/22) , and 22.5% (9/40) . There was no statistically significant difference between the positive and negative groups in various clinical indexes (P ＞ 0.05) . ConclusionAntiTPO antibody may not be the main mechanism of thrombocytopenia in PSS patients, and there is a certain correlation between TPO and inflammatory factors.
ObjectiveTo investigate the effects and safety of intravitreous injection of Conbercept combined with laser photocoagulation for macular edema secondary to branch retinal vein occlusion. MethodsAll subjects were assigned randomly to 3 groups:intravitreal Conbercept combined with laser photocoagulation group (CL group), intravitreal triamcinolone combined with laser photocoagulation group (TL group), and photocoagulation group (L group). The best-corrected visual acuity (BCVA), central macular thickness (CMT), fundus oculi and fundus fluorescein angiography (FFA), intraocular pressure (IOP), slit lamp were observed before and 1 day, 1 week, 1 month, 3 months after treatment. The changes of post-treatment BCVA and CMT in pre-therapy and post-treatment were compared, and related complications were recorded. ResultsThere were significant differences of BCVA (χ2=9.754, 12.430, 17.424, 13.189) and CMT (F=10.614, 4.099, 4.927, 8.99) between 3 groups in post-treatment 1 day, 1 week, 1 month and 3 months. The numbers of subjects of improving and stabilizing BCVA in CL group were remarkably more than that in L group in every post-treatment follow-up time (P < 0.01), whereas the CMTs in CL group were significantly less than that in L group in every post-treatment follow-up time (P < 0.05). The CMTs in post-treatment 1 day, 1 week, 1 month, 3 months were thinner than that in pretreatment in CL group and TL group (P < 0.05). Meanwhile, there was no significant difference (P > 0.05)between any two CMTs in post-treatment 1 day, 1 week, 1 month and 3 months in CL group. Yet, the CMT in post-treatment 3 months was thicker than those in post-treatment 1 day, 1 week and 1 month in TL group(P < 0.05). And there was no significant difference(P > 0.05)between any two CMTs in post-treatment 1 day, 1 week and 1 month in TL group. There was no conspicuous difference in CMTs(P > 0.05)between in CL group and in TL group in every viewing time, except for that in post-treatment 3 months(P < 0.05). There was only 1 case of intraocular hypertension in post-treatment in TL group. ConclusionsIntravitreous injection of Conbercept combined with laser photocoagulation for macular edema secondary to BRVO is effective, safe, and superior to laser photocoagulation only. Also it had a longer effective duration and less complications than intravitreal triamcinolone combined with laser photocoagulation.
ObjectiveTo determine the retinal thickness of normal children 3-6 years old and its relationship with the age and gender. MethodsIn a cross-sectional study, 480 eyes of 240 normal preschool children including 115 male and 125 female, ages 3 to 6 years in the urban of Beijing, China were included. The average age was (4.93±0.77) years old. The visual acuity, slit-lamp microscopy and frequency domain optical coherence tomography (FD-OCT, Optvue, Inc. USA) were examined. The retinal thickness of the macular fovea and 500, 750, 1500 μm from temporal and nasal side around the fovea were measured. 32 eyes were excluded from the study because they couldn't cooperate. Pearson correlation analysis was used to determine the correlation between age and macular retinal thickness. Independent samples group t-test was used to compare the differences between boys and girls. ResultsThe mean thickness of macular fovea was (169.10±20.587) μm. The mean macular thickness of boys was significantly higher than girls (t=-4.549, -6.167, -5.492, -5.163, -6.749, -7.494, -6.874; P≤0.001). The mean thickness of 500 μm and 750 μm from nasal side of macular fovea were significantly higher than temporal side (t=5.594, 15.778, 7.678, 18.180; P < 0.001). There was no significant relevance between macular thickness and age. ConclusionsThe mean macular thickness of boys is significantly higher than girls in normal children in the urban of Beijing. There is no significant relevance between macular thickness and age.
ObjectiveTo discuss the changes of joint fluid and blood-related indexes in patients with gouty arthritis and rheumatoid arthritis, and to analyze the clinical significance of these changes. MethodsSeventy-five patients with gouty arthritis and 68 with rheumatoid arthritis treated between January and December 2014 were included in our study. Their joint fluid-related indicators including white blood cell count (WBC), total protein (TP), albumin (ALB), glucose (GLU), and uric acid (UA), and their blood indicators including immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin A (IgA), C3 and C4, rheumatoid factor (RF), anti-streptolysin O (ASO), and c-reactive protein (CRP) were detected. ResultsFor joint fluid-related indicators, TP and ALB levels were not significantly different between the two groups (P > 0.05), while WBC, GLU, UA, RF and ASO between the two groups were significantly different (P < 0.05); For blood indexes, C4 was not significantly different between the two groups (P > 0.05), but IgG, IgM, IgA, CRP, C3, UA, RF and ASO were significantly different between the two groups (P < 0.05). The detection rate of ASO from the joint fluid was significantly higher than that detected from the blood in both the two groups (P < 0.05), while UA level was not significantly different between the joint fluid and the blood (P > 0.05). In patients with rheumatoid arthritis, RF detection rate was not significantly different between the joint fluid and the blood (P > 0.05), but it was significantly different for patients with gouty arthritis (P < 0.05). The positive rate of ASO in the blood and joint fluid of patients with gouty arthritis was respectively 38.7% and 44.0%, and it was 75.0% and 73.5% for patients with rheumatoid arthritis. UA positive rate in the blood and joint fluid of patients with gouty arthritis was 92.0% and 80.0% respectively, while it was 38.2% and 32.4% for patients with rheumatoid arthritis. RF positive rate was 33.3% and 40.0% in the blood and joint fluid of patients with gouty arthritis, while the rate was 86.8% and 91.2% for patients with rheumatoid arthritis. ConclusionThe joint fluid and blood indicators are in change in patients with gouty arthritis and rheumatoid arthritis, which has a certain clinical value in disease diagnosis and curative effect observation.
ObjectiveTo observe the efficacy of self-behavior management combined with glucosamine hydrochloride for patients with early knee osteoarthritis. MethodsBetween October 2013 and March 2015, 240 patients with early knee osteoarthritis were randomly assigned to behavior therapy group (n=80) , drug treatment group (n=80) and combined treatment group (n=80) . Patients in the behavior therapy group were treated only by self-behavior management; patients in the drug treatment group were treated by glucosamine hydrochloride (0.48 g, three times per day); patients in the combined treatment group were treated by self-behavior management combined with glucosamine hydrochloride. The effect of treatment, adverse reactions, efficiency and expulsion rate were assessed 4, 8 and 12 weeks after treatment. ResultsThe Lequesne index and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) significantly decreased from week 4 when compared with week 0 after treatment in the combined treatment group, and there was a significant difference between the combined treatment group and single therapy group at week 8 and 12 (P ＜ 0.05) . The Lequesne index in the behavior therapy group and drug treatment group began to significantly decrease from week 8, and the WOMAC score significantly decreased from week 4 in the drug treatment group and from week 8 in the behavior therapy group. The efficiency increased with the treatment time prolonged in all three groups, but the efficiency in the combined treatment group was significantly higher than the single therapy group (P ＜ 0.05) . The shedding rates in the behavior therapy group, drug treatment group and combined treatment group were respectively 12.5%, 7.5% and 6.3%, without statistically significant difference (P ＞ 0.05) . The adverse reaction rate was low in all the three groups. ConclusionThe self-behavior management combined with glucosamine hydrochloride is an effective, safe and well-tolerated treatment for early knee osteoarthritis.
Objective To investigate the relationship between the gastrointestinal function and ventilator-associated pneumonia (VAP) in critically ill patients who underwent invasive mechanical ventilation. Methods One-hundred and fifty-three cases of critically ill patients receiving mechanically ventilation were recruited in the study. After 5 days of ventilation, the gastrointestinal function score and the C-reactive protein (CRP) of each patient were recorded. The incidence of VAP was recorded during hospitalization. According to the incidence of VAP, all patients were divided intoaVAP group and a non-VAP group. The relationship between gastrointestinal function score and the incidence of VAP was analyzed. The relationship between CRP level and severity degree of VAP was also analyzed. Results VAP occurred in 42 cases with the incidence of 27.45%. The gastrointestinal function score (1.9±1.0 vs. 0.8±1.0, P < 0.05) and CRP level [(52.38±12.06) mg/L vs. (36.69±11.08)mg/L, P < 0.05] were both higher in the VAP group than those in the non-VAP group. At gastrointestinal function score of 0 - 3, the CRP levels were all higher in the VAP group than those in the non-VAP group (P < 0.05). The incidence of VAP was 8.33%, 23.68%, 45.45%, and 59.09% at gastrointestinal function score of 0, 1, 2 and 3, respectively, with significant differences between each other(P < 0.05). Conclusion For critically ill patients receiving invasive mechanical ventilation, the more severe the damage of gastrointestinal function is, the higher the incidence of VAP is, and the more serious the disease is.
