ABSTRACT
Objective:To compare the efficacy between olecranon sled fixation and tension band wiring fixation in the treatment of Mayo ⅡA olecranon fractures.Methods:A retrospective study was conducted to analyze the data of 54 patients with Mayo ⅡA olecranon fracture who had been admitted to Department of Traumatology and Orthopedics, Beijing Jishuitan Hospital from October 2018 to February 2021. There were 20 males and 34 females with an age of (45.5±17.7 years), and 36 left and 18 right sides. They were divided into 2 groups according to different methods of internal fixation. Group A (25 cases) was subjected to olecranon sled fixation and group B (29 cases) to tension band wiring fixation. Preoperative data, operation time, reoperations and complications during follow-up were recorded and compared between the 2 groups. In both groups at the last follow-up, the range of the elbow motion, the Mayo elbow performance score (MEPS) and the Disabilities of the Arm, Shoulder and Hand (DASH) score were recorded to evaluate the elbow function.Results:The 2 groups were comparable because there were no significant differences in all their preoperative demographic data ( P>0.05). There were no significant differences between the 2 groups either in follow-up time [(32.8±8.9) months for group A and (35.8±9.0) months for group B] or in operation time [60.0 (60.0, 82.5) min for group A and 60.0 (60.0, 67.5) min for group B] ( P>0.05). At the last follow-up in group A and group B, respectively, the flexion and extension of the elbow was 141.0°±8.4° and 140.0 (140.0, 150.0)°, the pronation-supination 180.0 (175.0, 180.0)° and 180.0 (175.0, 180.0)°, the MEPS score 100.0 (85.0, 100.0) and 100.0 (92.5, 100.0), and the DASH score 4.2 (1.7, 6.3) and 5.8 (1.3, 8.3), all showing no statistically significant differences between the 2 groups ( P>0.05). Olecranon skin irritation occurred in 5 patients (20.0%,5/25) in group A and in 15 patients (51.7%,15/29) in group B, and 7 patients (28.0%,7/25) in group A and 21 patients (72.4%,21/29) in group B underwent removal of internal fixation, both showing statistically significant differences between the 2 groups ( P<0.05). Conclusion:In the treatment of Mayo ⅡA olecranon fractures, compared with tension band wiring fixation, olecranon sled fixation may lead to comparable efficacy in fixation and functional recovery, but significantly reduced rates of complications and internal fixation removal.
ABSTRACT
Elbow arthrolysis is the most commonly used treatment for elbow stiffness. Ulnar nerve complications are one of the most important evaluation indicators of postoperative health status. However, there is no consensus on the management of ulnar nerve and the control of surgical indications. Combining relevant literature and clinical experience, this review discussed the necessity of ulnar nerve release and the choice of ulnar nerve operations during elbow arthrolysis with or without preoperative ulnar nerve symptoms. It is considered that more attention should be paid to the management of ulnar nerve complications and further research should be performed.
ABSTRACT
As the most effective treatment for acute ischemic stroke, intravenous thrombolysis can not only improve the outcome of patients, but also affect post-stroke depression (PSD) through direct or indirect mechanisms. Therefore, it is of great clinical significance to explore the effect of intravenous thrombolysis on PSD. This article reviews the characteristics of PSD, the possible impact and mechanisms of intravenous thrombolysis on PSD, and the prevention and treatment of PSD.
ABSTRACT
Undifferentiated connective tissue disease (UCTD) has clinical and laboratory characteristics of connective tissue disorders, but it can not meet the diagnostic criteria of any specific disease. Pregnancy complicated with UCTD is one of the most common rheumatic diseases in women of childbearing age. UCTD will increase the risk of adverse events of pregnancy, such as spontaneous abortion, preeclampsia, fetal growth restriction, small for gestational age,recurrent implantation failure and so on. Pregnancy may lead to recurrence, aggravation and even serious complications of UCTD; multidisciplinary monitoring and appropriate treatment can improve the pregnancy outcome.
ABSTRACT
Olecranon fracture is one of the most common types of elbow fracture. The traditional surgical methods are tension band wiring and plate internal fixation. Both surgical methods can well restore the range of motion and function of the elbow, but there are still problems such as occurrence of complications and high rate of secondary surgery. Olecranon sled is a new type of internal fixation, the unique design of which helps reduce the incidence of complications. Combining relevant literature and clinical experience, the author will discuss the research progress in common internal fixation techniques for olecranon fracture, considering that the clinical effect of internal fixation is good at present, but the problems of postoperative complications and secondary operation are still worthy of attention.
ABSTRACT
Objective:To investigate the effect of psychological support during perithrombotic period on post-stroke depression (PSD) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS received intravenous thrombolysis in the Affiliated Lianyungang Hospital of Xuzhou Medical University from January 1, 2021 to July 31, 2021 were enrolled prospectively. The intervention group received one-to-one individual psychological support therapy in the perithrombolytic period on the basis of receiving standard intravenous thrombolytic therapy. At 30 d after onset, Hamilton Depression Scale was used to assess whether PSD occurred. Multivariate logistic regression analysis was used to evaluate the independent influencing factor of PSD. Results:A total of 126 patients with AIS were enrolled, and 86 of them were male (68.25%). Their age was 63.65±10.46 years; 65 were in the intervention group and 61 were in the control group. The incidence of PSD in the intervention group was significantly lower than that in the control group (20.00% vs. 36.07%; χ2=4.049, P=0.044). Multivariate logistic regression analysis showed that psychological intervention (odds ratio [ OR] 0.333, 95% confidence interval [ CI] 0.132-0.838; P=0.020] was an independent protective factor for PSD, while ischemic heart disease ( OR 4.510, 95% CI 1.181-17.217; P=0.028), alcohol consumption ( OR 3.421, 95% CI 1.317-8.888; P=0.012), anticoagulation therapy ( OR 3.145, 95% CI 1.155-8.567; P=0.025) and modified Rankin Scale score before thrombolysis ( OR 1.627, 95% CI 1.142-2.317; P=0.007) were the independent risk factors for PSD. Conclusion:Perithrombolytic psychological support may reduce the incidence of PSD.
ABSTRACT
Objective:To investigate the therapeutic effects of sled board internal fixation on the treatment of olecranon fractures.Methods:The clinical data were retrospectively analyzed of the 21 patients with olecranon fracture who had been treated with sled board internal fixation at Department of Traumatology and Orthopedics, Beijing Jishuitan Hospital from May 2019 to January 2021. They were 11 males and 10 females with 14 left and 7 right sides affected, aged from 18 to 68 years (mean, 42.0 years). By the preoperative Mayo classification for olecranon fractures, one case was type ⅠA, 11 cases were type ⅡA and 9 cases type ⅡB; by the Schatzker classification, one case was type A, 4 cases were type B and 16 cases type C. The operation time and the complications were recorded; at the last follow-up, the range of motion of the elbow joint was recorded and the elbow function and pain were evaluated by the Mayo elbow performance score (MEPS) and visual analogue scale (VAS).Results:The 21 patients were followed up for 13 to 34 months (mean, 19.6 months) after operation. At the last follow-up, the flexion and extension of the affected elbow averaged 139.8° (from 125° to 160°), and the pronation-supination 177.9° (from 160° to 180°). The operation time averaged 77.8 min (from 40 to 135 min). Postoperative olecranon skin discomfort developed in 4 patients, 2 of whom underwent removal of internal fixation; no such complication as internal fixation breakage, screw loosening, incision infection or elbow stiffness was observed in the other 17 cases. At the last follow-up, the MEPS scores averaged 97.9 points (from 85 to 100 points) and the VAS scores 0.2 points (from 0 to 2 points).Conclusion:The sled board internal fixation can result in good therapeutic effects on the treatment of olecranon fractures.
ABSTRACT
Objective:To investigate the correlation between total cholesterol (TC)/high-density lipoprotein cholesterol (HDL-C) ratio and unstable carotid plaque.Methods:From February 2021 to May 2021, adult patients with asymptomatic carotid atherosclerotic plaque admitted to the Department of Neurology, the First People's Hospital of Lianyungang were retrospectively enrolled. The demographic and related clinical data were collected. Carotid artery plaques were detected by ultrasound, and the subjects were divided into a stable plaque group and an unstable plaque group. Multivariate logistic regression analysis was used to assess the independent risk factors for unstable carotid plaques. Receiver operating characteristic (ROC) curve was used to evaluate the predictive efficacy of TC/HDL-C ratio for unstable carotid plaques. Results:A total of 362 patients with asymptomatic carotid atherosclerotic plaque were enrolled, including 226 (62.43%) in the stable plaque group and 136 (37.57%) in the unstable plaque group. Multivariate logistic regression analysis showed that after adjusting for confounding factors, only TC/HDL-C ratio was the independent risk factor for unstable carotid plaque (taking the 1 st quintile array of TC/HDL-C ratio as a reference, the 4 th quintile array: odds ratio 3.13, 95% confidence interval 1.50-6.55, P=0.002; the 5 th quintile array: odds ratio 6.75, 95% confidence interval 3.21-14.22, P<0.001). ROC curve analysis showed that the area under the curve of TC/HDL-C ratio for predicting unstable carotid plaque was 0.691 (95% confidence interval 0.634-0.748; P<0.001), the optimal cut-off value was 4.38, and the sensitivity and specificity were 50.0% and 82.7%, respectively. Conclusion:TC/HDL-C ratio is an independent risk factor for unstable carotid plaques and has a certain predictive value for unstable carotid plaques.
ABSTRACT
Blood pressure management is an important and complex part of the treatment of acute ischemic stroke. There is no consensus on blood pressure management options for patients with acute ischemic stroke receiving intravenous thrombolysis. Blood pressure levels and blood pressure variability before and after thrombolysis, and timing of blood pressure interventions have significant effects on hemorrhagic transformation, functional outcome, and recurrence risk in patients with acute ischemic stroke. This article reviews the necessity, safety, goals of blood pressure management before and after thrombolysis, and its impact on the outcomes in acute ischemic stroke.
ABSTRACT
Objective To investigate the relationship between low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio (LHR) and asymptomatic carotid plaques and their stability in high-risk stroke population.Methods Between December 2012 and April 2015,a total of 39 944 permanent resident population ≥40 years were used as subjects of the survey from 11 rural communities in Haitou Town,Banzhuang Town and Tashan Town,Ganyu District,and 9 urban communities in Xinpu District and Haizhou District,Lianyungang City using epidemiological survey method of cluster sampling.Excluding those who took lipid-lowering drugs within 3 months and had a history of stroke or transient ischemic attack,6 592 people at high risk of stroke were finally screened out.Ultrasound was used to detect carotid plaques.The subjects were divided into plaque-free group and plaque group.The latter was further divided into stable plaque group and unstable plaque group.Multivariate logistic regression analysis was used to evaluate the independent risk factor for carotid plaques and their stability.The odds ratio (OR) and 95％ confidence interval (CI) were calculated.Receiver Operating Characteristic (ROC) curve was used to evaluate the prediction efficiency of LHR on carotid plaques.Results Multivariate logistic regression analysis showed that low-density lipoprotein cholesterol (LDL-C) was an independent risk factor for carotid plaques,while high-density lipoprotein cholesterol (HDL-C) was an independent protection factor of carotid plaques.Using the lowest quintile (Q1) of LHR as a reference,carotid plaque risk increased significantly with the increasing LHR (Q2:OR 1.448,95％ CI 1.082-1.937,P =0.013;Q3:OR 2.414,95％ CI 1.754-3.322,P＜0.001;Q4:OR 2.939,95％ CI 1.945-4.441,P＜0.001;Q5:OR 4.884,95％ CI 3.143-7.115,P＜0.001).ROC curve analysis showed that the area under the curve (AUC) of LHR predicting carotid plaques was 0.795 (95％ CI 0.792-0.807;P＜ 0.001),and the optimal cut-off value was 3.00 (sensitivity 68.37％,specificity 75.65％).LHR ≥3.92 (LHR in the Q4 and Q5 subgroups) was an independent risk factor for unstable carotid plaques (OR 2.915,95％ CI 2.104-4.040;P＜0.001).The AUC of the LHR predicting unstable carotid plaques was 0.658 (95％ CI 0.633-0.684;P＜0.001).Conclusions LHR was an independent predictor of carotid plaques in high-risk stroke patients.It had higher predictive value for carotid plaques,and its conversion threshold for promoting plaque formation was 3.00.When LHR was ≥3.92,there was a significant increase in the risk of unstable carotid plaques.

ABSTRACT
Objective To identify Chinese character writing related cortex (WRC) and its relationship with hand motor cortical areas. Methods Ten native Chinese-speaking, right-hand volunteers were recruited in the study. NTMS mapping was conducted during picture naming task. The WRC were mapped based on nTMS-induced impairment of Chinese character writing. The extent and area of WRC was calculated. The right-hand motor representations were mapped while motor-evoked potentials were produced under nTMS stimulation. EMG data and coordinates of positive stimulus were recorded. The relationship between WRC and hand motor cortex (HMC) was analyzed on the basis of area comparison and distance calculation. Results The cortical areas related to Chinese character writing were mapped successfully in all subjects by nTMS. WRC was primarily centered in left posterior middle frontal gyrus (pMFG) (86%,55/64). The mean WRC area (161.03 mm2 ±62.58mm2) was significantly smaller than the mean HMC area (589.50 mm2±227.34mm2) (P<0.001). The WRC and HMC were not conjoined or overlapped in the dominant hemisphere. The distance between those two was 12.58mm±2.71mm. Conclusions NTMS can provide reliable assistance in mapping WRC areas. The WRC is relatively fixed and centralized in pMFG but is not overlapped with the HMC.

ABSTRACT
Objective To investigate the correlation between morning blood pressure surge and Coronary Microvascular Dysfunction.Methods 58 cases of patients with hypertension in our hospital were given 24 h ambu-latory blood pressure monitoring(ambulatory blood pressure monitoring,ABPM).The coronary microvascular dys-function was estimated by the index of microcirculatory resistance(IMR). All cases were given biochemical test-ing,included TCH,TG,HDL-c,LDL-c and SUA.Results According to whether ABMP was arise,the patient were divided into MBPS group(n=21)and the Non-MBPS group(n=37).24 h,day,night and morning peak of systolic blood pressure were significantly higher in the morning peak group than in the average morning peak group. Multiple linear regression analysis showed that,MBPS,24 h average systolic blood pressure,day average systolic blood pressure,night average systolic blood pressure,and age were independent risk factors for coronary artery disease.Conclusion Morning blood pressure surge is closely related to severity of coronary microcirculation dysfunction. It is an independent risk factor for coronary microcirculation dysfunction. To control the blood pres-sure in patients with hypertension effectively can reduce morning peak target organ damage.

Methods A total of 196 CHD with IGT and 160 controls were included. The changes of plasma lipid indexes and coronary artery atherosclerotic plaque in TaqI B genotypes were analyzed before and after Rosovastatin therapy. Sequenom Mass ARRAY platform was used to detect the CETP TaqI B SNPs. Results The genotype frequency of the B1B1, B1B2 and B2B2 in CHD with IGT group was 35.7%, 48.0% and 16.3% respectively, while in control group was 31.3%, 53.1% and 15.6% respectively. HDL-C, PA and MLA levels increased after Rosuvastatin therapy, while LDL-C, TG, TCH, Lpa, PA, EEMA and PB levels decreased. Conclusions CETP gene polymorphisms TaqI B would have association with the effects of Rosuvastatin therapy in the CHD with IGT.
ABSTRACT
Objective To compare the adverse reactions of intranasal and intravenous dexmedetomidine on tracheal extubation during wake up of general anesthesia.Methods One hundred and twenty patients who ASA Ⅰ or Ⅱ grade were divided into four groups (each 30 patients) by random digits table method.The patients in intravenous group were given 0.5 μ g/kg intravenous dexmedetomidine (diluted to 10 ml by 0.9％ sodium chloride,intravenous injection slowly,≥30 s).The patients in intranasal group 1 were given 0.5 μg/kg intranasal dexmedetomidine.The patients in intranasal group 2 were given 0.8 μg/kg intranasal dexmedetomidine.The patients in control group were given intravenous 0.9％ sodium chloride.The systolic blood pressure(SBP),mean arterial blood pressure (MAP),heart rate were compared among groups.Eyes open time and extubation time,the rate of cough and the degree during extubation were compared too.Results The SBP,MAP,heart rate in intravenous group,intranasal group 1 were significantly higher than those in basal state (P ＜ 0.05).The SBP,MAP,heart rate at different time in intranasal group 2 had no significant difference (P ＞ 0.05).The SBP,MAP,heart rate before extubation and after extubation for 3 min in control group were significantly higher than those in intravenous group,intranasal group 1 and intranasal group 2 (P ＜ 0.05).Eyes open time and extubation time among four groups had no significant difference(P ＞0.05).The rate of cough,restlessness and 3 scores of degree before extubation in intravenous group,intranasal group 1 and intranasal group 2 were significandy lower than those in control group [43％ (13/30),50％(15/30),47％(14/30) vs.70％ (21/30); 17％(5/30),23％(7/30),20％(6/30) vs.43％(13/30);53％ (16/30),60％ (18/30),50％ (15/30) vs.80％ (24/30)] (P ＜ 0.05).Conclusions Either intravenous or intranasal dexmedetomidine can effectively prevent the stress reaction during extubation,decrease the degree of restlessness and cough.Intranasal dexmedetomidine(0.8 μ g/kg) is more effective and safe.
ABSTRACT
Objective To investigate the electrophysiological changes of peripheral nerves in both patients with hereditary neuropathy with liability to pressure palsies(HNPP).Methods The nerve conduction velocities of a family consisting of a proband and 4 members were tested,and the proband was detected by biopsy.Results The proband's median nerve,ulnar nerve,sural sensory nerve conduction velocity (SCV) were decreased.The median nerve,ulnar nerve,common peroneal nerve motor nerve conduction velocity(MCV) of proband were decreased.The sensory fibers of the most frequently involved nerve sural nerve,sural nerve damage to the results:the motor nerve conduction motor nerve evoked potential latency and 18 abnormal rate was 75.0％,the nerve distal to the abnormal rate of MCV was 87.5％.Conclusion Prolongation of distal nerve conduction latencies occurs in essentially all individuals whether symptomatic or asymptomatic.Nerves may be more easily damaged at the site of compression.
ABSTRACT
Objective To investigate any changes in motor functional connectivity in the brains of acute ischemic stroke patients after low frequency electrical stimulation.Methods Twenty-five ischemic stroke patients were given low frequency electrical stimulation in addition to their conventional rehabilitation treatment.Another 20 patients received only conventional treatment as a control group.Resting-state functional magnetic resonance imaging (rs-fMRl)was employed to assess motor function connectivity in the brains of all 45 subjects before and after treatment.Any differences in functional impairment,extremity motor function or ability in the activities of daily living were also recorded before and after treatment.Results In both groups,average scores on the Canadian neurological scale (CNS)and the National Institutes of Health stroke scale (NIHSS) had been reduced significantly after treatment and FuglMeyer assessment (FMA) and modified Barthel index (MBI) scores had significantly increased.The average improvements in terms of FMA and MBI scores were significantly greater in the observation group.Compared with before treatment,the coefficient of functional connectivity of the bilateral motor cortex had decreased significantly after treatment in both groups.In the observation group the changes were significantly correlated with the improvements in FMA scores.Conclusion Neural functional impairment after ischemic stroke can be reduced significantly and extremity motor function and ability in the activities of daily living can be significantly improved by low frequency electrical stimulation.
