Methods A total of 32 patients with traumatic hemorrhagic shock were randomly divided into polygeline injection group and HES group,with 16 patients in each. The same measures such as hemstasis, expanding blood volume, correction of acid base disturbance and so on were adopted in the both groups. The patients in the polygeline injection group and HES group were respectively treated with polygeline injection and HES NaCl injection in a dose of 1500 mL by intravenous infusion. The time from injection to the recovery of BP, urinary output, and blood gas to normal level was recorded. Results BP, urinary output, and blood gas were all improved significantly, there was no significant difference between the two groups (Pgt;0.05). Conclusion The clinical effect of polygeline injection on stabilizing BP and improving microcirculation appears comparable to that of HES.
ObjectivesTo systematically review the efficacy of Chinese herbal medicine (CHM) combined with chemotherapy for ovarian cancer.MethodsCNKI, VIP, WanFang Data and PubMed databases were searched to collect randomized controlled trials on the CHM combined with chemotherapy for ovarian cancer from inception to March 31st, 2018. Two reviewers independently screened literature, extracted data and evaluated the risk bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsThirteen studies were included. Meta-analysis showed that, CHM combined with chemotherapy group was superior to the chemotherapy alone group in effective rate of TCM syndrome (RR=1.72, 95%CI 1.46 to 2.03, P<0.00.000 1), effective rate of tumor change (RR=1.40, 95%CI 1.21 to 1.63,P<0.000 01), physical condition score (MD=9.19, 95%CI 5.89 to 12.48,P<0.000 01), tumor markers (MD=–18.00, 95%CI –20.62 to –1.538,P<0.000 01), leukocyte reduction (RR=0.67, 95%CI 0.58 to 0.77,P<0.000 01), granulocy tedepletion (RR=0.67, 95%CI 0.55 to 0.81,P<0.000 1), thrombocytopenia (RR=0.55, 95%CI 0.45 to 0.69,P<0.000 01), and digestive tract reaction (RR=0.66, 95%CI 0.50 to 0.87,P=0.004).ConclusionsThe current evidence shows that CHM combined with chemotherapy is superior to chemotherapy alone in the treatment of ovarian cancer. Due to limited quality and quantity of included studies, the above conclusions are required to be verified by more high-quality studies.
Lipid globules in retina and choroid are new definitions based on pathology and high-resolution optical coherence tomography (OCT). OCT examination shows that the lipid globules are low reflective circular cavities in the choroid and retina, without strong reflective boundaries around them, followed by a characteristic superreflective tail. It occurs in healthy human eyes and in age-related macular degeneration characterized by retinal pigment epithelium (RPE) atrophy. Its characteristic superreflective tail is the key to distinguishing it from other diseases. At present, the understanding of lipid globules is still in the initial stage. Although lipid globules can be observed in healthy human eyes, a certain prevalence rate indicates that they are associated with choroidal hypoperfusion and RPE atrophy. In the future, larger randomized controlled trials and longer follow-up time are needed to explore its pathogenesis, pathological characteristics and treatment prognosis.
Objective To investigate the expression of eotaxin-1, eotaxin-2 and eotaxin-3 in ARPE-19 human RPE cells after exposure to light. Methods Cultured human RPE cells (5th~10th generations) were divided into lightinduced group and control group. Cells light-induced group were exposed to the blue light at the intensity of (600plusmn;100) Lux for 12 h to establish the light damaged model. Eotaxin-1, eotaxin-2 and eotaxin-3 mRNA and protein were determined by real time polymerase chain reaction and Western blot at 0, 3, 6, 12, 24 hours after light-induced. Results In light-induced groups, mRNA levels of eotaxin-1 and eotaxin-2 were increased at 0 h (t1=6.05.t2=12.561) and 3 h （t1=2.95.t2=3.67） significantly(P＜0.05), but the mRNA level of eotaxin-3 had not changed （t3=1.57 and 1.00 respectively，P＞0.05） at that time. At 6 h （t1=4.73，t2=18.64，t3=28.48）, 12 h （t1=3.11，t2=20.62，t3=18.50）, 24 h （t1=8.25，t2=38.27，t3=18.60）, mRNA levels of eotaxin-1, 2, 3 were increased significantly （P＜0.05）. Except for the eotaxin-3 protein had not changed at 3 h （t3=1.28，P＞0.05）, protein expression of eotaxin-1, 2, 3 were increased significantly （P＜0.05） at 0 h （t1=4.85，t2=5.45，t3=6..21）, 3 h （t1=5.64，t2=4.55）, 6 h （t1=31.60，t2=6.63，t3=7.15）, 12 h （t1=14.09，t2=18.22，t3=15.76）, 24 h （t1=6.96，t2=10.47，t3=12.85）. Conclusion Eotaxin-1, eotaxin-2 and eotaxin-3 expression were increased after Light-damage, corresponding to the time after light exposure. Eotaxin-3 was the most prominent isoform.
ObjectiveTo observe the blood perfusion changes of peripapillary and macular vessels in patients with nonarteritic anterior ischaemic optic neuropathy (NAION).MethodsRetrospective cohort study. Thirty-six eyes (19 affected eyes and 17 fellow eyes) of 19 patients with NAION diagnosed in People’s Hospital of Wuhan University from November 2017 to January 2019 were included in this study. There were 10 males and 9 females, with the mean age of 55.05±7.11 years. Forty eyes of 20 normal subjects matched with NAION patients were included as controls. BCVA, fundus color photography, SD-OCT and OCT angiography were performed in normal controls and repeated in NAION affected eyes at 1-2 weeks, 1-2 months, 3-5 months intervals. OCT quantitative measurements: average retinal nerve fiber layer thickness (aRNFL) of the disc and its superior values (sRNFL) and the inferior values (iRNFL), average ganglion cell complex thickness (aGCC) in macular region and its superior values (sGCC) and the inferior values (iGCC). OCTA quantitative measurements: average radial peripapillary capillary density (aRPC) and its superior values (sRPC) and the inferior values (iRPC), average vascular density of superficial retina (aSVD) in macular region and its superior values (sSVD) and the inferior values (iSVD), average vascular density of deep layer retina (aDVD), areas of foveal avascular zone (FAZ). The differences of OCT and OCTA quantitative measurements between NAION eyes and the fellow eyes and normal controls were comparatively analyzed. Independent sample t test, paired sample t test or nonparametric rank sum test were performed for comparison among three groups. Pearson or Spearman correlation analysis were used to analyze the correlation between RNFL and RPC, GCC and SVD, RNFL and GCC, RPC and SVD.ResultsAt baseline, the aRNFL, aRPC and aDVD of NAION patients were significantly higher than those of normal controls. Compared with the fellow eyes, the aRNFL increased significantly and the aRPC decreased significantly in NAION affected eyes. The overall differences of aRNFL, aRPC, aGCC and aSVD at four intervals within NAION affected eyes were statistically significant (P＜0.05). The average sRNFL, sRPC, sGCC and sSVD at 1-2 months interval were significantly lower than the average iRNFL, iRPC, iGCC and iSVD (P＜0.05). Correlation analysis: at 1-2 months interval, aGCC was positively correlated with aSVD (r=0.482, P=0.037); at 3-5 months interval, aRNFL was positively correlated with aRPC (r=0.631, P=0.037).ConclusionThere is a sectorial reduction of vascular density of peripapillary RPC and macular SVD with the disease progression of NAION.
ObjectiveTo systematically review the comprehensive evaluation methods applied to estimate the medical service performance based on diagnosis-related groups (DRGs) in China and to provide suggestions for the promotion of methods in further studies.MethodsLiterature published before May 2019 were searched in China National Knowledge Infrastructure, WanFang Data, CQVIP and PubMed for studies about DRGs-based comprehensive evaluation. After literature screening and information extracting by two reviewers independently, qualitative approaches were used to describe the application of DRGs-based comprehensive evaluation methods in the performance evaluation of medical services.ResultsA total of 24 articles were included in the systematic review. Different indexes were used to evaluate the medical service performance. Delphi Method, expert discussion, Saaty’s Method and some other means were applied to determine the weights of indexes in 8 articles. Rank-sum ratio method, Technique for Order Preference by Similarity to an Ideal Solution and synthetic index method were proposed for the comprehensive evaluation in 9, 7 and 9 articles, respectively; besides, analytic hierarchy process and combination evaluation were also used.ConclusionsBased on DRGs, the choose of indicators, weighting approaches, and calculation methods of comprehensive values vary richly in different studies. More attention should be paid to weight using and combination of comprehensive evaluation methods in further studies. Meanwhile, the quality of information source used for estimation and the rationality of results application are supposed to be emphasized.
ObjectiveTo observe the changes of eotaxin-1(CCL11), eotaxin-2(CCL24)and eotaxin-3(CCL26)in ranibizumab treated light-injured human retinal pigment epithelium (RPE) cells ARPE-19 and investigate the effects of vascular endothelial growth factor (VEGF) antagonist to the expressions of eotaxins. MethodsCultured human RPE cells(8th-12th generations)were divided into light-injured group, ranibizumab treated group and normal control group. Cells of the three groups were exposed to the blue light at the intensity of(600±100) Lux for 12 h to establish the light injured model, while cell culture dishes of the normal control group were wrapped with double-layer foil. The cells of ranibizumab treated group were treated with VEGF-A antagonist(ranibizumab)at the final concentration of 0.125 mg/ml for 24 hours directly after the illumination. The mRNA and protein of VEGF-A, eotaxin-1, eotaxin-2, eotaxin-3, NF-κB were determined by Real time-PCR, enzyme-linked immunosorbent assay, Western blot, immunohistochemical staining at 0, 3, 6, 12, 24 hours after light damage. ResultsThe mRNA and protein level of VEGF-A, eotaxin-1, eotaxin-2, eotaxin-3, NF-κB in the light-injuried group increased significantly compared to that in normal control group (P < 0.05). After treating with ranibizumab, the expression of eotaxin-1, eotaxin-2, eotaxin-3, NF-κB were significantly suppressed (P < 0.05). ConclusionThe suppression of over-expression of VEGF in human RPE may down-regulate the expression of eotaxins, via the suppression of NF-κB.
Objective To observe the angiographic features of patients with retinal vein occlusion (RVO) by ultra-wide-field fluorescein angiography (UWFA) and compare with the conventional 7 standard field (7SF) imaging. Methods This is a retrospective clinical description study. Fifty-eight eyes of 56 RVO patients were included. There were 25 males (26 eyes) and 31 females (32 eyes). The age ranged from 25 to 69 years, with a mean age of (48.12±18.56) years. The course of disease was from 2 days to 25 months, with a mean course of (12.78±11.35) months. Thirty eyes were diagnosed with central RVO (51.72%), 26 eyes were diagnosed with branch RVO (44.83%) and 2 eyes were diagnosed with hemicentral RVO (3.45%). Retinal laser photocoagulation was performed in 11 eyes (18.97%). All patients received examinations of UWFA (British Optomap 200Tx imaging system) and optical coherence tomography (OCT). Using the protocol for obtaining 7SF images as described in the Early Treatment Diabetic Retinopathy Study, 7 circular regions with a range of 30 degrees were combined as the 7SF template to determine the observation area. This template was then overlaid on the UWFA image to identify the potential viewable area of 7SF. The visualized retinal area, retinal non-perfusion area, retinal neovascularization area, and laser spot area of UWFA and 7SF were quantified by a retinal specialist. In addition, the OCT images of the affected eye were observed and analyzed to confirm the existence of macular edema. Correlation analysis was done between retinal non-perfusion, retinal neovascularization and macular edema detected by UWFA. Results The results of UWFA and 7SF examination were the same. Compared with 7SF, UWFA showed 3.53 times more retinal visual area, 3.31 times more non-perfusion area, 1.94 times more neovascularization area, and 3.59 times more laser spots (t=72.13, 4.69, 1.76, 5.78;P=0.000, 0.005, 0.102, 0.000). Lesions of 11 eyes (18.97%) were found outside the range of 7SF images. By UWFA, non-perfusion area correlated with neovascularization and macular edema (χ2=12.13, 4.82;P=0.000, 0.028;C=0.42, 0.28). Non-perfusion area anterior to the equator have significantly correlations with macular edema (χ2=6.32,P=0.012,C=0.31), but non-perfusion posterior to the globe equator have no relevance with macular edema (χ2=2.88,P=0.090, C=0.22). Conclusions UWFA can detect more peripheral retinal lesions than 7SF images. By UWFA, non-perfusion area has correlation with neovascularization and macular edema.
