ABSTRACT

Open ocular trauma in children is one of the main causes of non-congenital monocular blindness in children. Children’s psychological and daily activities are different from those of adults; the eye tissue structure is not maturely enough, and the characteristics of high response to injury and incompatibility with various diagnostic and treatment methods determine the factors that cause injuries and injuries in children with open ocular trauma. The environment, diagnosis and treatment, and prognosis of children are more complicated than adults. For the emergency of first and second stage on diagnosis and treatment of children with open ocular trauma, it should follow the principles of adult open ocular trauma management, combined with the children's characteristics, clarifying the anatomical location of the ocular trauma before surgery, and closing the wound during the first-stage operation. At the same time, the disturbance of intraocular tissue should be minimized, the timing of the second stage operation and the individualization of the operation design, and the medication and care after the operation should also be combined with the characteristics of children. Prevention of ocular trauma in children is the focus of attention. In the new information era, clinical research and public information platforms should be fully utilized to advance the epidemiological study of children's ocular trauma and guide the construction of the prevention and treatment system for children's ocular trauma more scientifically.

ABSTRACT

Objective:To observe the clinical effect of 3D digital head-up vitreoretinal surgery and conventional optical microscope surgery in the treatment of persistent fetal vasculature (PFV).Methods:A retrospective case analysis study was performed. From November 2017 to August 2019, the enrolled patienres included that 20 eyes of 19 patients with PFV undergoing 3D digital head-up vitreoretinal surgery and 26 eyes of 26 patients with PFV undergoing traditional microscopic vitrectomy in the Eye Center of Beijing Tongren Hospital. The operation age of patients in the two groups were ≤14 years old and followed up for at least 1 month. There were no significantly statistical differences in gender ( χ2=0.114), age ( t=0.337), axial length ( t=0.578) between the two groups ( P=0.267, 0.782, 0.650). All the patients were operated under general anesthesia by the same doctor. All the surgical procedures were completed by the surgeon watching the 3D screen with 3D glasses, and all the surgical process were observed by the other medical staff including the nurses and the anaesthetists in the observation group. While in the observation group, the surgical doctor and one assistant doctor watched the surgery through the operating microscope, the other doctors watched the 2D surgical video system. The general information, pre-and postoperative visual acuity, anatomical changes and surgical complications were reviewed and compared between the two groups. Difficulty and complexity of each surgery were classified by the chief surgical doctor into 5 scores. 1: easy, 2: a little difficult, 3:much difficult, 4 very difficult; 5:most difficult. Opinions of medical staff majored in or not majored in ophthalmology were also recorded. Independent sample t test was used to compare the count data between the two groups, while chi-square test was used to compare the measurement data. Results:The average operating time was 34.7±8.5 minutes and the difficulty score was 2.8±0.9 in the observation group. The average operating time was 37.5±1.6 minutes and the difficulty score was 3.1±1.1 in the comparison group. There was no significant statistically differences between the two groups ( t=0.782, 0.938; P=0.703, 0.562). Seven eyes had visual acuity improvement at last visit while 13 eyes with no changes compared with pre-operative visual acuity in the observation group, 8 eyes showed visual acuity improvement at last visit while 18 eyes showed no changes compared with pre-operative visual acuity in the comparison group. There was no significantly statistical differences between the two groups ( χ2=0.279, P=0.254). No surgical complications such as endophthalmitis or secondary glaucoma were observed in the two groups. 3D digital system showed better stereoscopic pictures and better resolution compared with traditional microscopic vitrectomy. All the medical staff which participated in the surgery preferred to the 3D digital vitrectomy system. Conclusions:3D heads-up digital vitrectomy shows better stereoscopic pictures and better resolution. 3D heads-up digital vitrectomy and traditional microscopic vitrectomy yielded comparable visual and anatomical outcomes for treatment of pediatric vitreoretinal diseases, however, there is not a significant difference in clinical outcomes.

ABSTRACT

Objective:To investigate whether the deficiency of death associated protein kinases (DAPK) 3 can reduce vascular calcification by inhibiting endoplasmic reticulum stress.Methods:The method of prospective cohort study was used to observe and analyze the cell culture in vitro.Human aortic vascular smooth muscle cells (VSMC) were cultured in F10K Kaighn′s modified medium, and divided into calcified group and non-calcified group according to whether β-phosphoglycerin (10 mmol/L) was added into the medium.The cells in calcified group and non calcified group were divided into DAPK3 inhibition group and its control group, endoplasmic reticulum stress inhibition group and its control group, mitogen-activated protein kinase (MAPK) activation group and its control group, DAPK3 inhibition + AMP-activated protein kinase (AMPK) inhibition and blank control group, respectively. DAPK3 mRNA and protein concentration, calcium content, alkaline phosphatase, protein concentration of VSMC differentiation marker genes (SM22α, α-SMA), osteogenic differentiation transcription factor (Runχ2, bone morphogenetic protein-2, BMP-2), endoplasmic reticulum stress markers (AFT4, GRP78, GRP94 and CHOP) and p-PAMK protein expression were measured.Results:The mRNA level(highest value was 15.24±0.72 on the 14th day ) and protein level(highest value was 11.31±0.38 on the 14th day) of DAPK3 were significantly higher than those in non calcified cells(5.63±0.62, 2.59±0.33, respectively). The difference was statistically significant ( P< 0.001). In the calcified cells, calcium content (86.54±8.21) mmol/g in dapk3 deficient group was significantly lower than that in control group (194.63±8.54) mmol/g ( t=22.35, P<0.001), alkaline phosphatase activity was significantly decreased((96.27±10.28) IU/g vs.(224.67±10.94) IU/g, t=20.951, P<0.001), the expression of the VSMC differentiation marker genes (SM22α, α-SMA) were upregulated significantly (SM22α: (0.82±0.14) vs.(0.44±0.13), t=4.872, P=0.001; α-SMA: (0.95±0.18) vs.(0.56±0.13), t=4.303, P=0.002), the level of bone differentiation transcription factor (Runχ 2, BMP2) was significantly decreased (Runχ 2: (1.12±0.28) vs.(2.21±0.35), t=5.957, P<0.001; BMP2: (0.82±0.12 ) vs.(1.26±0.16), t=5.39, P<0.001), MAPK level was up-regulated (DAPK3 inhibited group 0.74±0.12 of calcified cells, 1.04±0.14 of non calcified cells, higher than the control group 0.44±0.10 of calcified cells, 0.78±0.12 of non calcified cells, t=4.704, P=0.001; t=3.454, P=0.006), and the inhibited calcium content of ESR calcified cells significantly reduced (after inhibition of AMPK pathway, cells transfected with shRNA group 150.21±11.98, cells transfected with shRNA group 83.21±12.12 were lower than those transfection blank control group 164.82±12.34, P<0.001). The activity of alkaline phosphatase was significantly reduced (226.54±16.57) IU/g protein in the shRNA group and (112.34±15.96) IU/g protein in the shRNA group were significantly lower than 242.32±16.32 in the blank control group, P<0.001); calcium content and ALP activity in the calcified MAPK cells were significantly reduced ( P<0.001).

ABSTRACT

Objective To compare the changes in IFN-γ, IL-4, IL-10 and IL-1β expression at mRNA level in gastric mucosae of BALB/c, C57BL/6 and nude mice at different stages of Helicobacter heilmannii ( H. heilmannii) infection, and to investigate the types of induced immune responses. Methods Each kind of mice was randomly divided into two groups: infection ( n=30 ) and control ( n=6 ) groups. Those in the infection groups were intragastrically inoculated with H. heilmannii strains to establish long-term stable mouse infection models. Gastric mucosa tissues were collected at weeks 4, 8, 12, 24 and 36 and ana-lyzed by semi-quantitative RT-PCT to detect the expression of IFN-γ, IL-4, IL-10 and IL-1βat mRNA lev-el. Results In the early stage of infection (weeks 4-12), INF-γ, IL-4, IL-10, and IL-1β expression at mRNA level in the gastric mucosae of BALB/c and C57BL/6 mice were significantly increased compared with those of the control groups (P<0. 05). IL-4, IL-10 and IFN-γexpression peaked at weeks 8-12, while IL-1βexpression reached the peak at week 4. After 12 weeks, IFN-γexpression at mRNA level in BALB/c mice was significantly decreased, but showed no significant change in C57BL/6 mice. IL-4 expression at mRNA level in C57BL/6 mice at the late stage of infection (week 36) was lower than that in the correspond-ing control group (P<0. 05). Expression of IFN-γ, IL-4, IL-10 and IL-1β at mRNA level in nude mice were all higher than those in the control group, and there were significant differences in IL-1βand IL-4 ex-pression between groups (P<0. 05). Conclusions Expression of cytokines in H. heilmannii-infected mice increased over time. IFN-γ-mediated Th1 immune responses were the predominant immunity induced by H. heilmannii infection. Immune responses to H. heilmannii infection varied with the kinds of mice. C57BL/6 mice showed mainly Th1 cell immune responses, while Th1/Th2 mixed immune responses were induced in BALB/c mice.

ABSTRACT

Objective To observe manifestations of thyroid papillary carcinoma (PTC) in CEUS and planewave ultrasensitive imaging (AngioPLUS). Methods CEUS and AngioPLUS features of histopathologically proved PTC in 83 patients were retrospectively analyzed. According to CEUS enhancement, the patients were divided into hypo-enhancement group, iso-enhancement group and hyper-enhancement group. The differences of the peak intensity (PI) between lesion and adjacent thyroid tissue (ΔPI) were compared among 3 groups. The correlation of PI, ΔPI and CEUS enhancement of the lesions were evaluated, so as the correlation of CEUS enhancement, PI, ΔPI and the microvascular distribution showed with AngioPLUS. Results The differences of ΔPI among the 3 groups were statistically significant (χ2=52.35, P<0.001). ΔPI of hypo-enhancement group was less than that of iso-enhancement group (Z=-6.45, P<0.001) and hyper-enhancement group (Z=-3.99, P<0.001). ΔPI of iso-enhancement group was less than that of hyper-enhancement group (Z=-3.73, P<0.001). The differences of PI were statistically significant among 3 groups (F=34.97, P<0.001). PI of hypo-enhancement group was less than that of iso-enhancement group and hyper-enhancement group (both P<0.001). No significant difference was found for PI between iso-enhancement group and hyper-enhancement group (P=0.322). PI (rs=0.650, P<0.001) and ΔPI (rs=0.798, P<0.001) both had positive correlation with CEUS enhancement of the lesions. CEUS enhancement (rs=0.768, P<0.001), PI (rs=0.442, P<0.001) and ΔPI (rs=0.647, P<0.001) all had positive correlation with microvascular distribution demonstrated with AngioPLUS of the lesions. Conclusion CEUS enhancement of PTC showes positive correlation with microvascular distribution demonstrated with AngioPLUS of the lesions, which may be used to evaluate the perfusion indirectly of the lesions.

ABSTRACT

Investigations on the genetic diversity of Mycobacterium tuberculosis in China have shown that Beijing genotype strains play a dominant role. To study the association between the M. tuberculosis Beijing genotype and the drug-resistance phenotype, 1286 M. tuberculosis clinical isolates together with epidemiological and clinical information of patients were collected from the center for tuberculosis (TB) prevention and control or TB hospitals in Beijing municipality and nine provinces or autonomous regions in China. Drug resistance testing was conducted on all the isolates to the four first-line anti-TB drugs (isoniazid, rifampicin, streptomycin, and ethambutol). A total of 585 strains were found to be resistant to at least one of the four anti-TB drugs. The Beijing family strains consisted of 499 (53.20%) drug-sensitive strains and 439 (46.80%) drug-resistant strains, whereas the non-Beijing family strains comprised 202 (58.05%) drug-sensitive strains and 146 (41.95%) drug-resistant strains. No significant difference was observed in prevalence (χ= 2.41, P > 0.05) between the drug-resistant and drugsensitive strains among the Beijing family strains. Analysis of monoresistance, multidrug-resistant TB, and geographic distribution of drug resistance did not find any relationships between the M. tuberculosis Beijing genotype and drug-resistance phenotype in China. Results confirmed that the Beijing genotype, the predominant M. tuberculosis genotype in China, was not associated with drug resistance.

ABSTRACT

Objective To explore the association between estimated glomerular filtration rate (eGFR) and prognosis of acute ischemic stroke (AIS) patients who were treated by intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA).Methods We consecutively screened AIS patients who were treated by intravenous thrombolysis with rt-PA from January 2006 to September 2016 in Tangshan Gongren Hospital.According to eGFR value of patients at admission,the eligible patients were divided into two groups:normal eGFR group (eGFR ≥ 90 ml ? min-1 ? 1.73 m-2) and decreased eGFR group (eGFR < 90 ml? min-1 ? 1.73 m-2).The incidence of symptomatic intracerebral hemorrhage (SICH),early neurological deterioration (END) at 24 hours and seven days after thrombolysis,mortality within seven days and 90 days,and excellent recovery at 90 days were compared between the two groups.The OR with 95% CI and the adjusted OR with 95% CI were analyzed by univariate and multivariate Logistic regression models.Results A total of 258 patients were enrolled,including 182 cases in the normal eGFR group and 76 cases in the decreased eGFR group.After adjusting for the potential confounders,multivariate Logistic regression analysis showed that the rates of SICH (13.2% (10/76) vs 3.3% (6/182),OR =3.859,95% CI 1.313-11.341),END at 24 hours (21.1% (16/76) vs 8.2% (15/182),OR =2.958,95% CI 1.347-6.495) and seven days (32.9% (25/76) vs 12.6% (23/182),OR =3.129,95% CI 1.555-6.293),mortality within seven days (22.4% (17/76) vs 6.0% (11/182),OR =4.079,95% CI 1.588-10.477) and 90 days (23.7% (18/76) vs 9.9% (18/182),OR =2.457,95% CI 1.050-5.749) were higher in the decreased eGFR group than in the normal eGFR group.On the other hand,the chance of excellent recovery at 90 days (22.4% (17/76) vs 43.4% (79/182),OR =0.435,95% CI 0.229-0.824) was less in the decreased eGFR group than in the normal eGFR group.Conclusion Decreased eGFR may not only increase the risks of SICH,END and death,but also reduce the chance of 90-day excellent recovery in AIS patients after intravenous thrombolysis with rt-PA.

ABSTRACT

Objective To analyze the correlation of serum levels of galectin-3(Gal-3), N-terminal pro brain natriuretic peptide(NT-proBNP),brain natriuretic peptide(BNP)and C reactive protein(CRP)with prognosis of patients with decompensated acute attack of chronic heart failure (DAACHF),and to evaluate its significance in predicting mortality during 30-day hospitalization. Methods 103 DAACHF patients admitted in Peking University First Hospital and Capital Medical University-affiliated Beijing Anzhen Hospital Department of Cardiology from July 2012 to June 2015 were divided into death group(n=53,died of DAACHF)and survival group(n=50)matched for age, gender,cardiac function during 30-day hospitalization.Serum levels of Gal-3,NT-proBNP,BNP,CRP and the Minnesota Living with Heart Failure Questionnaire(MLHFQ)were retrospectively collected and compared on the first hospital day and 3 days,7 days,14 days after treatment.After 7 days of treatment,the serum levels of four markers were correlated with MLHFQ.The areas under the receiver operating characteristic(ROC)curve were used for estimating efficiencies of serum levels of four markers in predicting DAACHF patients' mortality during 30-day hospitalization. Results With prolonged treatment,the scores of Gal-3,NT-proBNP,BNP,CRP and MLHFQ were gradually increased in the group of death,and gradually decreased in survival group.The scores of Gal-3,NT-proBNP,BNP,CRP and MLHFQ were higher in the death group than in control group(P<0.05)at the day of hospital admission and at 3 days,7 days and 14 days after treatment(P<0.05).On 7 days after treatment,Gal-3,NT-proBNP, BNP,and CRP were positively correlated with MLHFQ score(r=0.748,0.730,0.6872,all P<0.01),and the areas under ROC curves predicting performance for mortality during 30-day hospitalization were 0.943, 0.907,0.876,0.867,0.913 for Gal-3,NT-proBNP,BNP,CRP and MLHFQ score,respectively,all P<0.01). Conclusions Serum levels of Gal-3,NT-proBNP,BNP and CRP were positively correlated with adverse prognosis for DAACHF patients,and they may be predictors of mortality during 30-day hospitalization with sequence effect of Gal-3>NT-proBNP>BNP>CRP.And their joint monitoring is better in predicting the prognosis of patients with heart failure.

ABSTRACT

Objective To explore the licorice herbs principal component isomer content and percentage change in differ-ent processing and extracting conditions.Methods RP-HPLC method were used with 18 beta glycyrrhizic acid(18β-Gly)and 18 alpha glycyrrhizic acid(18α-Gly)as the basis of evaluation,determination of main components and impurities of licorice pieces,effects of processing temperature and processing time on licorice pieces and standard mixture of principal components andimpuritiesthecontentof18-Glyand18α-Glyand18β-Glyratiochange.Results Duringtheprocessof Glycyrrhizauralen-sis Fisch,increasing the processing temperature and prolonging the processing time caused the decomposition of 18β-Gly and 18α-Gly,which was the main component isomer of licorice root,and the total content of licorice root was slightly decreased. During the processing,the main components did not change the conformation,and had no effect on the proportion of the two. The content of 18β-Gly and 18α-Gly content of glycyrrhizic acid in Glycyrrhiza uralensis Fisch after processing were lower than those before processing in 18β-Gly and 18α-Gly.Conclusion The processing time of licorice pieces could not be too long,the temperature could not be too high,so as to avoid excessive loss of active ingredients.Baking conditions suitable for baking tem-perature was 65 ℃,time was 1-2 h.The processing condition was convenient,the time and the temperature were controllable, and the sample quality was stable.

ABSTRACT

Objective: To observe the impact of vascular calcification on kidney injury rats with the expressions of β-Klotho, fibroblast growth factor receptor 1 (FGFR1) in kidney tissue in order to find the predictor for early chronic kidney disease (CKD), to provide the prevention and investigation basis of vascular calcification and CKD. Methods: Vascular calcification model was induced by vitamin D3 and nicotine injection in experimental rats and the animals were divided into 2 groups: Normal control group and Calcification group. n=6 in each group. Serum levels of creatinine and urea nitrogen were examined by sarcosine oxidase method and UV-glutamate dehydrogenase method respectively; blood levels of calcium and phosphorus were detected by biochemistry method; kidney tissue alkaline phosphatases (ALP) activity was measured by ALP detection kit, protein expressions of β-Klotho and FGFR1 were assessed by ELISA.Results: Compared with Normal control group, Calcification group showed increased serum levels of creatinine (35.200±4.087) umol/L vs (26.000±5.0990) umol/L and urea nitrogen (6.900±0.623) mmol/L vs (5.400±0.803) mmol/L, both P<0.05; elevated kidney tissue ALP activity (60.510±31.090) U/g vs (26.590±8.664) U/g and β-Klotho protein expression (9.052±1.238) ng/mg vs (6.860±1.036) ng/mg, both P<0.05. Blood levels of calcium, phosphorus and kidney tissue FGFR1 protein content were similar between 2 groups. Conclusion: Large dose vitamin D3 and nicotine injection may induce vascular calcification and early CKD symptom in experimental rats; β-Klotho protein expression was significantly increased suggesting that β-Klotho had been involved in the early regulation of vascular calcification and it could be used for the early diagnosis of CKD at certain point.

ABSTRACT

Objective To investigate the influencing factors of in-hospital delay using alteplase for intravenous thrombolytic therapy in patients with acute ischemic stroke.Methods From January 2006 to May 2015,220 consecutive patients with acute ischemic stroke admitted to the Department of Neurology,Tangshan Gongren Hospital Affiliated to North China University of Science and Technology were enrolled retrospectively.They all received alteplase for intravenous thrombolytic therapy.Their mean National Institutes of Health Stroke Scale (NIHSS) score on admission was 16±8.According to door-to-needle time (DNT),they were divided into either a delay group (DNT >60 min;n=151) or a non-delay group (DNT ≤60 min;n=69).The baseline data,laboratory tests,onset-to-door (OTD) time,imaging,and etiology classification of trial of org 10172 in acute stroke treatment (TOAST) of both groups were recorded.Univariate analysis was performed on both groups,and further multivariate logistic analysis was performed.Results (1) The proportion of the past history of transient ischemic attack,blood glucose level on admission,time from onset to hospital in the non-delay group were significantly higher than those of the delay group.There were significant differences between the two groups (43.5%[30/69] vs.3.3%[5/151],7.9±3.0 mmol/L vs.6.9±2.1 mmol/L,95±53 min vs.80±34 min,all P0.05).(2) Multivariate Logistic regression analysis showed that the risks of patients with the past history of transient ischemic attack (OR,0.330,95%CI 0.109-0.998,P=0.046),elevated blood glucose levels on admission (OR,0.775,95%CI 0.657-0.914,P=0.005),prolonged onset-to-door time (OR,0.648,95%CI 0.504-0.831,P=0.013),internal carotid artery lesions (OR,0.192,95%CI 0.038-0.960,P=0.044) for occurring in-hospital delay after thrombolysis were low.Systolic pressure on admission(OR,1.275,95%CI 1.091-1.491,P=0.027)and cardioembolism(OR,3.892,95%CI 1.661-9.112,P=0.006) for occurring in-hospital delay after thrombolysisin were high.Conclusion The patients with past history of transient ischemic attack,higher blood glucose,prolonged onset-to-door time,and having internal carotid artery lesions may be cause the attention of family members and doctors,and were less prone to having thrombolytic in-hospital delay,whereas those with higher systolic blood pressure on admission and cardioembolism were prone to having in-hospital delay.
