ABSTRACT

Objective To explore the value of dynamic ultrasound combined with 3.0T MRI for diagnosing and typing synovial plica of knee joint.Methods Dynamic ultrasound and 3.0T MRI data of 100 patients with suspected synovial plica of knee joint were retrospectively analyzed.Taking the results of arthroscopy as standards,the efficacy of dynamic ultrasound and 3.0T MRI alone and their combination for diagnosing synovial plica of knee joint were evaluated and compared.The length and thickness of synovial plica of knee joint measured with dynamic ultrasound,3.0T MRI alone and their combination were compared with those of arthroscopy,and the consistencies of the location and classification of synovial plica of knee joint with arthroscopy were analyzed.Results Synovial plica was detected in 70 cases,including 11 cases of supropatellar synovial plica,15 cases of infrapatellar synovial plica,medial patellar in 30 cases and lateral patellar synovial plica in 14 cases,among them type A,B,C and D were classified in 9,35,23 and 3 cases,respectively.No significant difference of sensitivity was found between dynamic ultrasound and 3.0T MRI alone for diagnosing synovial plica of knee joint(P>0.05),which were both lower than that of their combination(both P<0.05).The length and thickness of knee synovial plica measured with dynamic ultrasound and 3.0T MRI alone were lower than those measured with their combination and arthroscopy(all P<0.05),and there was no significant difference between the results of their combination and arthroscopy(both P>0.05).Dynamic ultrasound,3.0T MRI alone and their combination had high consistency of location(Kappa=0.755,0.826,0.897)and classification of knee synovial plica with those of arthroscopy(Kappa=0.721,0.744,0.860).Conclusion Dynamic ultrasound combined with 3.0T MRI was valuable for diagnosing and typing of synovial plica of knee joint.

ABSTRACT

Purpose To explore the correlation between phosphatidylinositol 3 kinase/serine-threonine kinase(PI3K/AKT)signaling pathway and elastic characteristics of breast lesions.Materials and Methods A total of 115 breast lesions were prospectively analyzed in 114 patients who underwent surgery from May 2021 to May 2022 at Chinese PLA General Hospital.Ultrasound and shear wave elastography were performed preoperatively.Immunohistochemical staining was used to detect the expression of PI3K/AKT protein levels in the tissue specimens,and the correlation between the staining results and the elastic parameters of shear wave elastography was analyzed.Results Surgical pathology revealed benign breast lesions in 50 cases and malignant lesions in 65 cases(25 cases with axillary lymph node metastasis).The maximum modulus of elasticity(F=40.47),the average modulus of elasticity(F=45.11),the ratio of elasticity of the lesion to that of the surrounding tissue(F=48.98),the detection rate of"hard ring sign"(χ2=62.25),the expression level of PI3K/p-PI3K(F=15.19,58.95)and AKT/p-AKT(F=46.94,74.21)were found in benign and malignant lesions without axillary lymph node metastasis,malignant lesions with axillary lymph node metastasis(all P<0.05).The expression levels of PI3K/p-PI3K and AKT/p-AKT were positively correlated with the maximum elastic modulus value,the mean elastic modulus value,and the ratio of elasticity of the lesion to the surrounding tissues(r=0.475,0.475,0.451;r=0.533,0.540,0.542;r=0.371,0.402,0.445;r=0.482,0.455,0.545,all P<0.05).Conclusion The expression level of PI3K/AKT in breast lesions is correlated with elastic characteristics,suggesting that it plays an important role in the regulation of elastic characteristics of breast lesions.

ABSTRACT

@#Objective To evaluate the relationship between the systemic immune-inflammation (SII) index,systemic inflammation response index (SIRI),and the severity and functional prognosis of patients with cervicocranial arterial dissection (CCAD). Methods A total of 101 patients with CCAD were enrolled and divided into the acute mild stroke group (n=48) and moderate to severe stroke group (n=15) caused by CCAD,and CCAD without stroke group (n=38). The SII index and SIRI were compared across the three groups. Logistic regression and receiver operating curve (ROC) analysis were performed to identify independent predictors of an unfavorable outcome and predictive power. Results Compared with CCAD without stroke group,patients with stroke had higher SII index and SIRI,and significantly higher values of these biomarkers were observed in patients with moderate/severe stroke than those with minor stroke (P<0.05). SII index and SIRI were associated with the NIHSS score at admission (rSII=0.306,PSII=0.002; rSIRI=0.271,PSIRI=0.006) and the mRS score at discharge (rSII=0.264,PSII=0.008; rSIRI=0.240,PSIRI =0.016). In multivariate analysis,elevated SII index,but not SIRI,was independently associated with poor short-term outcomes after CCAD (P<0.05). NIHSS score played a full mediation effect between SII index level and poor prognosis. The sensitivity of the SII index in predicting unfavorable clinical outcomes was 66.7%,the specificity was 82.6%,and the best critical value was 1 160.63×109/L. Conclusion Elevated SII index and SIRI values are associated with the severity and clinical outcomes of patients with CCAD. An elevated SII index,but not SIRI,could be an independent predicting factor for a poor short-term outcome after CCAD.

ABSTRACT

Objective:To compare the detection rate and time cost of different imaging methods for retinal and optic disc neovascularization in proliferative diabetic retinopathy (PDR).Methods:A cross-sectional study was conducted.Thirty-eight patients (48 eyes) with PDR were enrolled in Henan Eye Hospital from October 2019 to February 2021, including 22 males (28 eyes) and 16 females (20 eyes). The average age of the patients was (51.08±13.35) years.All patients underwent ultra-widefield imaging (UWFI), fundus fluorescein angiography (FFA), optical coherence tomography angiography (OCTA), en face optical coherence tomography (OCT), near-infrared fundus imaging (IR) combined with spectral domain OCT (SD-OCT). Wide field swept-source OCTA (WF-SS-OCTA) was performed in the patients who were unsuitable for FFA.The time required for each examination in one eye and the detection rate of neovascularization at the optic disc (NVD) and retinal neovascularization elsewhere (NVE) were recorded.This study adhered to the Declaration of Helsinki.The study protocol was approved by Henan Eye Hospital (No.HNEECKY-2021[22]). All patients were informed about the method and purpose of the study and voluntarily signed the informed consent form.Results:The mean monocular examination time costs of UWFI, IR+ SD-OCT, OCTA+ en face OCT, FFA and WF-SS-OCT was (0.51±0.13), (2.08±0.57), (5.79±0.68), (17.66±1.83) and (13.38±1.23)min, respectively.There was a significant overall difference in the mean monocular examination time among the five methods ( F=2 077.960, P<0.001). The detection rates of UWFI, IR+ SD-OCT, OCTA+ en face OCT, FFA+ WF-SS-OCT for NVE and NVD were 52.1%(25/48) and 12.5%(6/48), 81.3%(39/48) and 20.8%(10/48), 83.3%(40/48) and 27.1%(13/48), 93.8%(45/48) and 29.2%(14/48), respectively.There were significant differences in the detection rates of NVE ( χ2=26.460, P<0.001) but not in the detection rates of NVD ( χ2=4.645, P=0.200) among the various methods.Five neovascular buds were detected by OCTA in 3 eyes, but not by FFA. Conclusions:UWFI and IR+ SD-OCT are faster and non-invasive methods for the screening of NVD and NVE in PDR eyes.Compared with FFA, OCTA and en face OCT can show the shape of neovascularization more clearly.FFA provides a wide-range retinal image, but it is time-consuming and invasive.WF-SS-OCTA extends the examination range of OCTA and detects neovascularization non-invasively and faster than FFA.

ABSTRACT

In grating-based phase contrast imaging,the phase stepping technique is commonly utilized for data acquisition and signal retrieval from acquired intensity data.However,the algorithm efficiency with respect to the dark-field retrieval has yet to be sufficiently evaluated.Herein the algorithm efficiency of dark-field retrieval based on Cramér-Rao lower bound is evaluated.The theoretical analysis and numerical results demonstrates that fully efficient algorithm is currently available only for 3-step phase stepping technique,and other techniques with more phase steps are all sub-optimal.Quantitatively,the dependence of the algorithm efficiency on the phase step number and the visibility is investigated.It is shown that the phase stepping technique can nearly approach its theoretical optimal efficiency in the case of a low visibility.With a phase step greater than 5,the algorithm efficiency is only 77.4%in the case of a high visibility.The study can provide some reference for signal-to-noise ratio improvement and potential dose optimization in X-ray and neutron grating-based dark-field imaging.

ABSTRACT

Objective:To investigate the imaging features of iris fluorescein angiography (IFA) combined with fluorescein fundus angiography (FFA) in diabetic iridopathy.Methods:A cross-sectional study was conducted.Sixty-five eyes of 44 patients with proliferative diabetic retinopathy (PDR) combined with diabetic iridopathy (DI) were enrolled in Henan Eye Hospital from May 2013 to May 2020.Patients were divided into non-proliferative diabetic iridopathy (NPDI) group and rubeosis iridis group according to the imaging results.Ophthalmic examinations including visual acuity, intraocular pressure, slit lamp miacroscopy, IFA and FFA were carried out in all patients.IFA was used to detect the iris imaging characteristics and the regression time of fluorescein in anterior chamber, and FFA was used to observe the retinal image characteristics and the incidence of optic disc neovascularization.To avoid the statistical error of recording the IFA examination time of the contralateral eye, only the relevant data of the affected eyes were analyzed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2020[06]). Written informed consent was obatined from all patients before any medical examination.Results:Among the patients, 30 cases (50 eyes) were with NPDI and 14 cases (15 eyes) were with rubeosis iridis.The fluorescein regression time in anterior chamber of NPDI group was (3.37±0.11) minutes, which was significantly shorter than (6.02±0.29) minutes of rubeosis iridis group ( t=8.541, P<0.001). Strong fluorescence of retinal neovascularization was observed in both groups.The incidence of optic disc neovascularization in NPDI group was 20% (6/30), which was significantly lower than 50% (7/14) in rubeosis iridis group ( P=0.04). Conclusions:Diabetic rubeosis iridis can be diagnosed by the imaging features of IFA and the fluorescein regression time in anterior chamber.PDR combined with optic disc neovascularization should be evaluated by FFA combined with IFA.

ABSTRACT

【Objective】 To explore the relationship between climate factors and the number of street voluntary blood donors in Beijing and develop a reliable predictive model, so as to provide reference for donor recruitment. 【Methods】 The data of weather and the number of street blood donors from January 2018 to October 2019 were collected to formulate generalized additive model(GAM) and autoregressive integrated moving average model(ARIMA), and the predicative accuracy of the two models was assessed using data from November to December 2019. 【Results】 GAM indicated that the number of donors decreased when the wind force was 4 to 5 (95%CI: 0.805, 0.995), and the number on weekends and official holidays was 1.562 (95% CI: 1.510, 1.617) and 1.779 (95%CI: 1.035, 3.055) times that of the working day respectively. The number of blood donors increased with the elevation of temperature until 25℃, then declined with temperature increasing slowly. The two-day predictive accuracy of GAM and ARIMA was 92.14% and 90.55%, with overall accuracy at (84.46±11.12)% and (87.65±9.3)%, respectively. 【Conclusion】 Considering official holiday, strong wind and temperature, etc, the ARIMA model runs stable overall, while GAM is good at short-term prediction. The comprehensive use of two predictive models is helpful in guiding the recruitment of blood donors.

ABSTRACT

IntroductionThe purpose of this systematic review is to evaluate the efficacy and safety of using potential drugs: remdesivir and glucocorticoid in treating children and adolescents with COVID-19 and intravenous immunoglobulin (IVIG) in treating MIS-C. MethodsWe searched seven databases, three preprint platform, ClinicalTrials.gov, and Google from December 1, 2019, to August 5, 2021, to collect evidence of remdesivir, glucocorticoid, and IVIG which were used in children and adolescents with COVID-19 or MIS-C. ResultsA total of six cohort studies and one case series study were included in this systematic review. In terms of remdesivir, the meta-analysis of single-arm cohort studies have shown that, after the treatment, 37.1% (95%CI, 0.0% to 74.5%) experienced adverse events, 5.9% (95%CI, 1.5% to 10.2%) died, 37.2% (95%CI, 0% to 76.0%) needed extracorporeal membrane oxygenation or invasive mechanical ventilation. As for glucocorticoids, the results of the meta-analysis showed that the fixed-effect summary odds ratio for the association with mortality was 2.79 (95%CI, 0.13 to 60.87), and the mechanical ventilation rate was 3.12 (95%CI, 0.80 to 12.08) for glucocorticoids compared with the control group. In terms of IVIG, the two included cohort studies showed that for MIS-C patients with more severe clinical symptoms, IVIG combined with methylprednisolone could achieve better clinical efficacy than IVIG alone. ConclusionsOverall, the current evidence in the included studies is insignificant and of low quality. It is recommended to conduct high-quality randomized controlled trials of remdesivir, glucocorticoids, and IVIG in children and adolescents with COVID-19 or MIS-C to provide substantial evidence for the development of guidelines.

ABSTRACT

Objective:To observe the incidence of diabetic iridopathy and optic disc neovascularization in the contralateral eyes of proliferative diabetic retinopathy (PDR) with proliferative diabetic iridopathy (PDI).Methods:A retrospective case-control study. From February 2014 to May 2020, 72 eyes of 36 patients with PDR and PDI who underwent iris fluorescein angiography (IFA) combined with fluorescein fundus angiography(FFA) at the Henan Eye Institute were enrolled in the study. Among them, there were 34 eyes in 17 males and 38 eyes in 19 females; the average age was 62.3±4.7 years. All patients underwent best corrected visual acuity(BCVA), intraocular pressure, IFA combined with FFA examination. The BCVA examination was performed using the international standard visual acuity chart, which was converted into logarithm of the minimum angle of resolution BCVA for statistic analysis. According to PDI staging, patients were divided into early rubeosis iridis(RI) group and neovascular glaucoma (NVG) group, with 28 and 8 cases respectively. Compared with NVG group, RI group had better BCVA and intraocular pressure, and the difference was statistically significant( t=6.433, 10.619; P=0.000, 0.011). The incidence of PDI and the incidence of binocular optic disc neovascularization in the two groups were compared, and Fisher's exact probability method was used for comparison. Results:The results of the IFA examination showed that in the RI group, the pupil border and the iris surface of the iris of the affected eyes had strong neovascular bud-like or patchy fluorescence; the pupil border and the middle of the iris of the patients in the NVG stage had strong neovascular cluster-like fluorescence. Among the contralateral eyes in the RI group, 6 eyes (21.4%, 6/28) were with PDI (stage RI), 21 eyes (75.0%, 21/28) were with non-PDI (NPDI), and 1 eye (1/ 28, 3.6%) were absence of diabetic iris disease. Among the contralateral eyes in the NVG group, there were 5 eyes with PDI (62.5%, 5/8), including 4 eyes with RI stage, 1 eye with NVG stage (12.5%, 1/8); 3 eyes with NPDI. The image of IFA in patients with NPDI early showed as punctate fluorescence in the local small blood vessels of the iris itself. The incidence of PDI in the contralateral eye of the RI group was lower than that of the NVG group, and the difference was statistically significant ( P=0.040). The results of FFA examination showed that 9 (32.1%, 9/28) and 8 (28.6%, 8/28) eyes of the affected eye and the contralateral eye in the RI group were combined with optic disc neovascularization. In NVG group, there were seperately 6 eyes (75.0%, 6/8) in the affected eyes and the contralateral eyes with optic disc neovascularization. The differences in the incidence of optic disc neovascularization between the two groups of the affected eyes and the contralateral eye were statistically significant ( P=0.046, 0.040). Conclusion:The incidence of PDI and optic disc neovascularization in the contralateral eye of PDR and PDI, RI is lower than that of NVG.

ABSTRACT

【Objective】 To investigate the tension of donors during blood donation, so as to explore the utmost period for proper psychological intervention. 【Methods】 The donation procedure, from the completion of blood donation consultation form to the end of blood donation was divided into 17 steps, and donors were asked to recall the degree of tension at each step after the donation. 【Results】 71.65%(207/293) of the donors reported tension during donation, dominated by female donors(P<0.05)and first-time donors(P<0.05). The beginning of phlebotomyis the most intense moment.First-time donors (P<0.05), accidental donors (P<0.05) and female donors (P<0.05) were more nervous than others. Statistical differences in needle fear before and after the donation was observed(P<0.05). Multivariate analysis indicated that donation history and fear of puncture would affect the nervous level during donation. 【Conclusion】 More attention should be paid to female donors and first-time young donors to improve their self-efficacy and reduce the tension by explaining the donation procedure in detail, promoting donation appointment, and shielding the needles and blood bags.

ABSTRACT

Objective:To compare the efficacies of MRI, X-ray mammography (XMG) and Ultrasound (US) in detecting and diagnosing breast ductal carcinoma in situ (DCIS).Methods:Two hundred and forty one consecutive patients with pathology-confirmed DCIS were retrospectively recruited from January 2011 to December 2017 in PLA General Hospital. The imaging examination modalities included MRI and/or XMG and/or US.The breast imaging reporting and data system (BI-RADS) categorizations by MRI, XMG and US were compared and their sensitivities of detecting DCIS were calculated. The causes of underestimation on MRI were interpreted with the information of XMG and US. Chi-square test was used to compare the differences.Results:The diagnostic sensitivity of XMG, US and MRI was 65.9% (29/44), 71.6% (101/141) and 91.2% (145/159), respectively, with statistical significant differences (χ2 =24.034, P<0.001). Breast density and lesion type would influence the sensitivity of XMG. And the sensitivity of US was decreased because of non-mass lesion. Of the 14 cases under-evaluated as BI-RADS category 1 to 3 on MRI, 5 were corrected by XMG and/or US to BI-RADS category 4. The cause of underestimation on MRI was the coexistence of DCIS with adenoma or other benign lesion. Conclusion:The retrospective comparison of MRI, XMG and US in this study showed that MRI had significant higher sensitivity in detecting breast DCIS, while the false negative rates of XMG and US were un-negligible.

ABSTRACT

Peripheral nerve hyperexcitability syndromes (PNHS) encompass a spectrum of a heterogeneous condition with clinical as well as electrophysiological manifestations of peripheral nerve hyperexcitability. The PNHS consist of Isaacs syndrome, Morvan syndrome and Cramp-fasciculation syndrome, which cause widespread symptoms and signs while without evident peripheral nerve disease. Probably the most well-known condition of PNHS is Isaacs syndrome, often called acquired neuromyotonia. Clinical symptoms of PNHS are characterized by muscle twitching, cramps, stiffness, and neuropathic pain. The electrophysiological findings that are very useful in the diagnosis of PNHS are spontaneous myokymic, neuromyotonic, and cramp discharges. An overview of the history, clinical manifestations, pathophysiology, electrophysiological findings and management of PNHS is presented.

ABSTRACT

Objective Evaluating the effects of Bushen-Gufeigao and breathing movements on the patients with chronic obstructive pulmonary disease of Lung and kidney deficiency TCM pattern. Methods The patients with chronic obstructive pulmonary disease of lung and kidney deficiency TCM pattern were recruited and randomly divided into two groups the treatment group (32 cases) and the control group (34 cases). The control group was treated with the conventional medicine, and the treatment group were added Bufei-Gushengao and breathing movements based on the treatment of control group. Both groups were treated for 1 month. The changes of the clinical symptoms, lung function and frequency of attack and duration of each attack in 10 months after treatment were observed. Results After the treatment, compared with the control group, the TCM patterns scores (5.32 ± 2.67 vs. 9.12 ± 4.11, t=4.424) of the treatment group significantly decreased, while the FVC (3.00 ± 0.49 L vs. 2.71 ± 0.47 L, t=2.408), FEV1 (2.27 ± 0.44 L vs. 1.85 ± 0.54 L, t=3.496), and the percentage of FEV1%(75.62 ± 6.84 vs. 66.86 ± 9.32, t=4.333) increased significantly. In the 10 mouths after the treatment, the treatment group showed significantly fewer patients who had attacked more than 6 times than that in the control group, and the duration of attacks showed significantly fewer minutes in the treatment group than the control group (5.56 ± 1.45 d vs. 8.06 ± 1.80 d, t=6.190). Conclusion Bushen-Gufeigao and breathing movements can effectively improve patient's lung function and symptoms.

ABSTRACT

Purpose To explore the expressional differences of immunohistochemical indicators between the non-mass-like and mass-like breast cancers,and to identify the biological characteristics of non-mass-like breast cancer.Material and Methods Various immunohistochemical indicators (HER2,ER,PR,Ki-67) were analyzed in 19 cases non-mass-like cancer and 18 cases mass-like breast cancer retrospectively,and the expressional differences of the two groups were compared.Results 12 cases (63.2%) were diagnosed DCIS in the non-mass-like breast cancer group,but in the mass-like breast cancer group,the majority (12 cases,66.7%) were invasive cancer.HER2,ER,PR expression had no statistical difference between the two types (P>0.05).But the Ki-67 positive rate expressed in non-mass-like breast cancer was lower significantly (P<0.05).Conclusion The HE immunohistochemical characteristics of non-mass-like breast cancer are overlapped with that of mass-like breast cancer,but Ki-67 expression has significant difference between the two groups.There are some differences in biological characteristics of these two kinds of breast cancers.

ABSTRACT

Background Neovascular glaucoma (NVG) is secondary to retinal ischemia and hypoxia.Iris fluorescein angiography (IFA) can be used for early detection of NVG,but it can not reflect the condition of retinal blood vessels comprehensively.IFA combined with fundus fluorescein angiography (FFA) can detect the condition of retina and iris neovascularization comprehensively,but its application on diabetic retinopathy(DR) with NVG was rare in China.Objective This study was to evaluate the clinical application of IFA combined with FFA in proliferative diabetic retinopathy (PDR) patients with NVG.Methods A retrospectively study was designed.One hundred and thirty-three eyes with PDR were enrolled in Henan Eye Hospital from February 2013 to January 2016,including 100 eyes with no iris diseases,21 eyes with rubeosis iridis,and 12 eyes with NVG.All eyes underwent ophthalmic examinations that included best-corrected visual acuity,intraocular pressure,slit lamp,IFA and FFA.The differences of IFA examination and slit lamp examination in the eyes with rubeosis iridis were compared and statistical analyzed by McNemar nonparametric test.Results In this study,100 eyes with no iris leakage were identified by IFA,32 eyes with panretinal photocoagulation (PRP) treatment history had no retinal neovascularization and 68 eyes had retinal neovascularization;21 rubeosis iridis eyes with iris leakage at pupillary border or on iris surface were observed at the early stage of IFA,and all the eyes were identified having retinal neovascularization according to FFA images;12 NVG eyes were observed having iris neovascular leakage on iris surface at the early stage of IFA,and all the eyes were identified having retinal neovascularization according to FFA images.The detection rate of IFA examination on rubeosis iridis was 100% (21/21),which was higher than 71.43% (15/21) of slit lamp examination,and there was a significant difference between the two detection methods (P =0.03).Conclusions IFA combined with FFA can detect PDR with rubeosis iridis early,and it is helpful to guide the treatment timely.
