RESUMEN
Phosphodiesterase 4 (PDE4) is an important member of the phosphodiesterase enzyme family that specifically catalyzes the hydrolysis of cyclic adenosine monophosphate (cAMP), activates the downstream phosphorylation cascade pathway by altering cAMP concentration, and is strongly associated with multiple diseases. Inhibition of PDE4 is clinically investigated as a therapeutic strategy in a broad range of disease areas, including respiratory system diseases, autoimmune disorders, central nervous system diseases, and dermatological conditions. However, the incidence of adverse reactions such as nausea and vomiting is relatively high in the marketed PDE4 inhibitors, which has stalled their clinical development. In this review, we provide an overview of the clinical progression and safety issues of the marketed PDE4 inhibitors. We also review the main causes underlying PDE4-mediated adverse effects by combining the structural analysis of the PDE4 protein, the mechanism of action of PDE4 inhibitors, and the related side effect mechanism research, aiming to provide a reference for the development of safe and effective PDE4 inhibitors.
RESUMEN
Objective: To analyze the efficacy and safety of letermovir in primary prophylaxis of cytomegalovirus (CMV) reactivation in patients receiving haploidentical hematopoietic stem cell transplantation. Methods: This retrospective, cohort study was conducted using data of patients who underwent haploidentical transplantation at Peking University Institute of Hematology and received letermovir for primary prophylaxis between May 1, 2022 and August 30, 2022. The inclusion criteria of the letermovir group were as follows: letermovir initiation within 30 days after transplantation and continuation for≥90 days after transplantation. Patients who underwent haploidentical transplantation within the same time period but did not receive letermovir prophylaxis were selected in a 1∶4 ratio as controls. The main outcomes were the incidence of CMV infection and CMV disease after transplantation as well as the possible effects of letermovir on acute graft versus host disease (aGVHD), non-relapse mortality (NRM), and bone marrow suppression. Categorical variables were analyzed by chi-square test, and continuous variables were analyzed by Mann-Whitney U test. The Kaplan-Meier method was used for evaluating incidence differences. Results: Seventeen patients were included in the letermovir prophylaxis group. The median patient age in the letermovir group was significantly greater than that in the control group (43 yr vs. 15 yr; Z=-4.28, P<0.001). The two groups showed no significant difference in sex distribution and primary diseases, etc. (all P>0.05). The proportion of CMV-seronegative donors was significantly higher in the letermovir prophylaxis group in comparison with the control group (8/17 vs. 0/68, χ2=35.32, P<0.001). Three out of the 17 patients in the letermovir group experienced CMV reactivation, which was significantly lower than the incidence of CMV reactivation in the control group (3/17 vs. 40/68, χ2=9.23, P=0.002), and no CMV disease development observed in the letermovir group. Letermovir showed no significant effects on platelet engraftment (P=0.105), aGVHD (P=0.348), and 100-day NRM (P=0.474). Conclusions: Preliminary data suggest that letermovir may effectively reduce the incidence of CMV infection after haploidentical transplantation without influencing aGVHD, NRM, and bone marrow suppression. Prospective randomized controlled studies are required to further verify these findings.

Objective: To analyze the detection rate, clinical significance, and prognosis of Epstein-Barr virus (EBV) in the cerebrospinal fluid (CSF) of patients following allogeneic hematopoietic stem cell transplantation. Methods: A retrospective analysis was performed on 1100 patients who underwent the CSF virus test after allogeneic hematopoietic stem cell transplantation in Peking University People's Hospital between January 2017 and June 2022. Among them, 19 patients were screened positive for EBV in their CSF, and their clinical characteristics, treatment, and prognosis were analyzed. Results: Among 19 patients with EBV-positive cerebrospinal fluid, 12 were male and 7 were female, with 5 patients aged <18 years and 12 aged ≥18 years, with a median age of 27 (5-58) years old. There were 7 cases of acute myeloid leukemia, 8 of acute lymphocytic leukemia, 2 of aplastic anemia, 1 of Hodgkin's lymphoma, and 1 of hemophagocytic syndrome. All 19 patients underwent haploid hematopoietic stem cell transplantation, including 1 secondary transplant. Nineteen patients had neurological symptoms (headache, dizziness, convulsions, or seizures), of which 13 had fever. Ten cases showed no abnormalities in cranial imaging examination. Among the 19 patients, 6 were diagnosed with EB virus-related central nervous system diseases, with a median diagnosis time of 50 (22-363) days after transplantation. In 9 (47.3%) patients, EBV was detected in their peripheral blood, and they were treated with intravenous infusion of rituximab (including two patients who underwent lumbar puncture and intrathecal injection of rituximab). After treatment, EBV was not detected in seven patients. Among the 19 patients, 2 died from EBV infection and 2 from other causes. Conclusion: In patients who exhibited central nervous system symptoms after allogeneic hematopoietic stem cell transplantation, EBV should be screened as a potential pathogen. EBV detected in the CSF may indicate an infection; however, it does not confirm the diagnosis.

BACKGROUND@#The scale assessment was helpful in predicting the presence of antibodies to autoimmune encephalitis. This study aimed to evaluate the application of antibody prevalence in Chinese patients with epilepsy and encephalopathy (APE2-CHN) and response to immunotherapy in Chinese patients with epilepsy and encephalopathy (RITE2-CHN) for patients with different neuronal surface antibodies.@*METHODS@#A total of 1365 patients with epileptic seizures as the prominent feature in Xuanwu Hospital, Capital Medical University, from June 2016 to June 2020 were enrolled in our study. Of these, 915 patients with epilepsy of unknown etiology whose serum and/or cerebrospinal fluid samples were examined for autoimmune antibodies were selected. All patients were scored with antibody prevalence in patients with epilepsy and encephalopathy (APE2), response to immunotherapy with epilepsy and encephalopathy (RITE2), APE2-CHN, and RITE2-CHN scores.@*RESULTS@#Of the 915 patients, 191 patients were positive for neural-surface specific antibodies (115 N-methyl-D-aspartate receptor (NMDAR) Ab, 47 leucine-rich glioma-inactivated protein 1 (LGI1) Ab, 8 contactin-associated protein 2 (CASPR2) Ab, 4 AMPA2R-Ab, and 11 GABAR-B-Ab; 3 CASPR2-Ab and LGI1-Ab, 2 NMDAR-Ab and CASPR2-Ab, and 1 NMDAR-Ab and myelin-oligodendrocyte glycoprotein [MOG] Ab). The sensitivity and specificity of APE2 ≥4 in predicting the presence of neural-surface specific antibodies in our study were 74.35% and 81.77%, respectively, and the sensitivity and specificity of APE2-CHN ≥4 were 75.92% and 84.53%, respectively. Eight cases had an APE2 score <4 and APE2-CHN score ≥5; all these patients had memory decline as the prominent manifestation. We divided the patients into six groups according to the different antibodies. APE2-CHN scores showed higher sensitivity for the prediction of NMDAR-Ab, but lower sensitivity for LGI1-Ab. A total of 187/191 (97.91%) patients received immunotherapy and 142/191 (74.35%) patients benefited from the treatments. The patients who were positive for LGI1-Ab with RITE2-CHN ≥8 responded well to immunotherapy.@*CONCLUSIONS@#APE2-CHN had the highest value for predicting the positivity of NMDAR-Ab and RITE2-CHN evaluated the response of immunotherapy for anti-LGI1 encephalitis appropriately. However, RITE2 and RITE2-CHN do not appear to be good predictors of immunotherapy outcomes for patients with specific neuronal-surface antibodies and high APE2-CHN scores are often indicative of a poor response to immunotherapy.

Purpose: To evaluate keratocyte viability and proinflammatory cytokine secretion induced by HSV-1 infection. Methods: Keratocytes were separated from corneal tissues obtained with the SMILE procedure, and an in vitro system was established to study HSV-1 infection in human keratocytes. Cell viability, HSV-1 genomic DNA copy number, and the expression levels of α-SMA, ALDH1A1, phospho-p38, p38, phospho-IRF3, and IRF3 were evaluated. Antibody array and ELISA kits were used to measure the production of proinflammatory cytokines and chemokines. Results: We found that HSV-1 infection reduced cell viability and activated keratocyte transdifferentiation into corneal fibroblast-like cells. Furthermore, p38 inhibition improved cell viability and IFN-ß production and played an anti-inï¬ammatory role by reducing the production of proinflammatory cytokines and chemokines. Conclusions: Our study reveals an important role played by keratocytes during innate immune responses and identifies p38 inhibition as a potential therapeutic approach to control ocular HSV-1 infection.

Objective:To investigate the correlation between single-breath counting (SBC) and standard measures of pulmonary function in patients with spinal cord injury, to evaluate the value for predicting pulmonary function. Methods:Forty-two patients (24 with cervical injury and 18 with thoracic injury) were selected from October, 2018 to February, 2019 in outpatients and inpatients. SBC and standard laboratory spirometer tests were performed separately. The correlation of the outcome of SBC and lung function indicators including forced vital capacity (FVC), forced respiratory capacity in the first second (FEV1), FEV1/FVC, slow expiratory vital capacity (EVC) and all the predicted values on the percentage (%pred) were analyzed. A receiver operating characteristic (ROC) curve was constructed according to the lung function classification criteria. Results:The outcome of SBS was correlated with FVC, EVC as well as the percentage of predicted values (r = 0.723 to 0.760, P < 0.01 for the whole patients; r = 0.549 to 0.657, P < 0.01 for cervical ones; r = 0.623 to 0.847, P < 0.01 for thoracic ones), and was also correlated with FEV1 as well as the percentage of predicted values (r = 0.622 to 0.760, P < 0.01 for whole patients and cervical ones). The area under the ROC curve was 0.864 to 0.941. Conclusion:There is a good correlation between SBC and standard lung function for patients with spinal cord injury, suggesting an assistive diagnostic value for patients with reduced lung function.
RESUMEN
Objective:To explore the posture control of professional dancers. Methods:From April to August, 2017, 21 professional dancers from an international famous club were as experimental group. Matching the height and age, etc., 21 medical workers were recruited as control group. They were tested with Tetrax Balance Evaluation System, and assessed with Trunk Stability Test (TST) and the Star Excursion Balance Test (SEBT). Results:There was no significant difference on fail-time of TST and maximum distance of SEBT between right and left sides in both groups. The fail-time of TST was less in the experimental group than in the control group (t =-2.667, P < 0.05), as well as the maximum distance of SEBT (t = -3.991, P < 0.001). There was no significant difference on falling index between both groups (t = 1.810, P > 0.05). Conclusion:Compared with medical workers, professional dancers do better in static balance, but worse in dynamic balance. Their performance of posture control is almost the same as the others.
RESUMEN
Objective:To compare the expectation and perception of rehabilitation services for patients with work injury with or without early intervention. Methods:From August, 2017 to February, 2018, 350 inpatients with work injury accepted early intervention and non-early intervention were investigated with the modified ServQual scale. Results:There was no significant difference in the expectation between the inpatients accepted early intervention and non-early intervention (t < 1.904, P > 0.05). In both groups, expectation was the highest in assurance and responsiveness dimension, and the lowest in reliability dimension. The perception was higher in the early intervention group than in the non-early intervention group. In both groups, perception was the highest in tangibility, and the lowest in empathy. Conclusion:Early intervention of rehabilitation may improve the perception of services.
RESUMEN
Objective:To determine the test-retest reliability of lumbar passive reposition accuracy for older people. Methods:A total of 58 healthy older people stood on an isokinetic dynamometer, and passively moved their trunk forward and backward to the target positions as accurately as possible. The targeted positions were set as flexion forward 15°, 30° and 60°, and flexion backward 15°. The absolute error (AE) was recorded. They were tested again a week latter. The intraclass correlation coefficient (ICC) and standard errors of measurement (SEM and SEM%) were calculated. Results:The ICC of AE was 0.699 to 0.833 for all the subjects, SEM was 1.18 to 3.26, and SEM% was 26.84% to 37.13%. For the men, the ICC was 0.462 to 0.818, SEM was 1.60 to 3.68, and SEM% was 36.37% to 48.78%. For the women, the ICC was 0.782 to 0.891, SEM was 1.48 to 2.71, and SEM% was 28.48% to 33.34%. Conclusions:Lumbar passive reposition accuracy is some reliable to assess the position sense for older people. However, there are too large errors for clinical measurement, which need further improvment.
RESUMEN
Objective To apply the Baltimore Therapeutic Equipment (BTE), a kind of vocational training and evaluation system, in rehabilitaion of patients post traumatic upper extremity injury from work, and to observe the effects. Methods Inpatients from September, 2014 to August, 2015 for rehabilitation of traumatic upper extremity injury from work were selected as control group (n=42), and inpatients from September, 2015 to August, 2016 were selected as intervention group (n=36). Both groups received routine rehabilitation, while the control group received con-ventional work simulation training, and the intervention group received work simulation training with BTE, for four weeks. They were measured the standing lifting strength (elbow), squatting lifting strength, dynamic lifting strength (floor to waist), dynamic lifting strength (floor to shoulder), and grip strength of the injured hand and the healthy hand with BTE, before and after rehabilitation; while they were assessed with Disability of Arm Shoul-der and Hand (DASH). The incidence of return to work was investigated at six months of follow-up. Results The standing lifting strength (elbow) (t=4.290, P<0.001), squatting lifting strength (t=2.645, P=0.010), dynamic lifting strength (floor to waist) (t=2.639, P=0.010), dynamic lifting strength (floor to shoulder) (t=5.361, P<0.001), and grip strength of the injured hand (t=2.320, P=0.023) and the healthy hand (t=3.130, P=0.002) im-proved better in the intervention group than in the control group after rehabilitation. However, there was no sig-nificant difference between two groups in score of DASH (t=-0.851, P=0.398), as well as incidence of return to work (χ2=0.05, P=0.944). Conclusion BTE may help to improve the body function in patients post traumatic upper extremity injury from work. However, vocational rehabilitation should focus on the factors other than body function, to improve their return to work.

Objective To observe the short-term effect of comprehensive pulmonary exercise on the impaired respiratory function of convalescence patients suffered from cervical spinal cord injury. Methods From November, 2011 to December, 2016, 100 patients with cervical spinal cord injury (C3-C6,ASIA A-D) were randomly divided into control group(n=50)and observation group(n=50).The control group received rou-tine rehabilitation training,and the observation group added comprehensive pulmonary exercise.They were ex-amined with forced vital capacity(FVC),forced expiratory volume in first second(FEV1),maximum expiratory flow rate with remaining 25% vital capacity (MEF25%) and maximum ventilation volume (MVV) before and two months after intervention. Results The FVC,FEV1,MEF25% and MVV improved significantly in the observation group(t>4.110,P<0.001),and the D-value was more in the observation group than in the control group before and after intervention(t>4.390, P<0.001). Conclusion Comprehensive pulmonary exercise has short-term effect on pulmonary function in convalescent patients survived from cervical spinal cord injury.
RESUMEN
The aims of the present study were to determine the effects of heparin-derived oligosaccharides (HDOs) on vascular intimal hyperplasia (IH) in balloon-injured carotid artery and to elucidate the underlying mechanisms of action. An animal model was established by rubbing the endothelia within the common carotid artery (CCA) in male rabbits. The rabbits were fed a high-cholesterol diet. Arterial IH was determined by histopathological changes to the CCA. Serum lipids were detected using an automated biochemical analysis. Expressions of mRNAs for vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), vascular cell adhesion molecule-1 (VCAM-1), monocyte chemoattractant protein-1 (MCP-1), scavenger receptor class B type I (SR-BI), and ATP-binding cassette transporter A1 (ABCA-1) were analyzed using reverse transcription polymerase chain reaction assays. Expressions of VEGF, VCAM-1, MCP-1, SR-BI and ABCA-1 proteins were analyzed by Western blotting. Enzyme-linked immunosorbent assays were used to quantify expression levels of VEGF and bFGF. Our results showed that administration of HDO significantly inhibited CCA histopathology and restenosis induced by balloon injury. The treatment with HDOs significantly decreased the mRNA and protein expression levels of VEGF, bFGF, VCAM-1, MCP-1, and SR-BI in the arterial wall; however, ABCA-1 expression level was elevated. HDO treatment led to a reduction in serum lipids (total cholesterol, triglycerides, high-density and low-density lipoproteins). Our results from the rabbit model indicated that HDOs could ameliorate IH and underlying mechanism might involve VEGF, bFGF, VCAM-1, MCP-1, SR-BI, and ABCA-1.

@#Objective To investigate the effects of Kinesio taping on function of knees in girls. Methods 20 female students were tested the peak torque of centripedal and eccentric contraction of knee flexion and extension with Biodex isokinetic testing at 60°/s angular velocity, with Kinesio taping, placebo taping and without taping. Their amplitude root of mean square (RMS) of surface electromyography of vastus medialis (VM), rectus femoris (RM) and vastus lateralis (VL) were also recorded. Results For centripedal isokinetic contraction, the relative extensors peak torque was the most as Kinesio taping (P<0.01). There was no significant difference in relative flexor peak torque (P> 0.05). Standardized RMS of VM and VL were the least as Kinesio taping (P<0.01), but not significantly different of RF among all the conditions (P>0.05). For eccentric isokinetic contraction, the relative extensor peak torque of both extensors and flexors were the most as Kinesio taping (P<0.01), while the Standardized RMS of VM and VL were the least (P<0.01), but no significant difference was observed in RF (P> 0.05). Conclusion Kinesio taping may enhance the strength of centripedal, eccentric contractions of quadriceps and eccentric contractions of hamstring, and increase the muscle fibers recruitment of VM and VL.
RESUMEN
In this study, the effect of heparin-derived oligosaccharide (HDO) on platelet-derived growth factor (PDGF) induced vascular smooth muscle cells (VSMCs) proliferation and the related signal transduction mechanisms were investigated. MTT assays were used to measure VSMCs proliferation. Cell cycle distribution was analyzed by flow cytometry. The level of key regulatory proteins in PKC, MAPK and Akt/PI3K pathways were determined by RT-PCR, Western blot and immunocytochemical methods. Meanwhile, mRNA expressions of some proto-oncogenes were assayed by RT-PCR method. Our data showed that HDO (0.01, 0.1 and 1 μmol · L(-1)) inhibited 30 ng · mL(-1) PDGF-induced VSMCs proliferation in a dose-dependent manner, blocked the G1/S transition and inhibited the level of key regulatory proteins and some proto-oncogenes (P < 0.05). The results showed that HDO may decrease the key regulatory proteins expression, hence suppress the transcription of proto-oncogene and G1/S transition, finally inhibiting VSMCs proliferation.

Objective: To evaluate the prevalence and risk factors of microalbuminuria (MAU) in hospitalized patients. Methods: A total of 1 259 hospitalized patients undergoing detection of urinary microalbumin in 2012 were recruited from Tongji Hospital. They were divided into two groups according to the level of urinary microalbumin, with 907 cases in the normal albuminuria (NAU) group and 352 in the MAU group. The clinical data of the two groups were compared and the risk factors of MAU were analyzed. Results: The MAU prevalence was 27.9% in our study. Patients in the MAU group had an elder age and higher prevalence rates of type 2 diabetes mellitus, hypertension, and type 2 diabetes combined with hypertension compared with the NAU group (P80 years old,OR=1.668,95%CI 1.185-2.348) and type 2 diabetes mellitus (OR=1.718,95%CI 1.334-2.211) increased the risk for MAU in hospitalized patients. Conclusion: MAU is closely related to age and type 2 diabetes mellitus in hospitalized patients, which suggests that strict control of blood glucose and timely treatment can slow down diabetic nephropathy and cardiovascular disease in hospitalized patients.
RESUMEN
Objective To study the effects of recombinant human erythropoietin (rhEPO) on learning and memory functions and expressions of apoptosis-related proteins (P53 and Bcl-2) in rats induced by chronic cerebral ischemia.Methods Sixteen healthy male SD rats were randomly divided into control group and experimental group (n=8); the permanent bilateral occlusion of common carotid arteries in these rats was adopted to establish the chronic cerebral ischemia models; rats in the experimental group weekly received intranasal rhEPO delivery at the dose of 150 U/125 μL after chronic ischemia for 3 days,whereas models in the control group accepted equivalent volume of saline at the same time.Eight weeks after the inducement,Morris water maze test was performed to evaluate the movement and the spatial learning and memory capabilities.Morphology changes of cerebral cortex and hippocampal CA1 nerve cells were observed by HE staining.P53 and Bcl-2 proteins levels were detected by immunohistochemistry.The number of apoptotic cells was detected by means of TUNEL.Results Morris water maze test showed that shorter escape latency and higher frequency through platform in the experimental group were noted as compared with those in the control group (P<0.05).HE staining indicated that less pyramidal cells and more serious karyopyknosis changes of cerebral cortex and hippocampal CA1 nerve cells and thinner cerebral cortex in control group were noted as compared with those in the experimental group (P<0.05).Immunohistochemistry indicated that the experiment group had increased Bal-2 expression and mean gray value of P53 as compared with control group (P<0.05).TUNEL showed that the apoptotic cells of control group were significantly increased as compared with those in the experimental group (P<0.05).Conclusion The rhEPO can improve the abilities of movement,memory and spatial orientation in rats induced by chronic cerebral ischemia,whose mechanism might be related to the restrain apoptosis.
RESUMEN
<p><b>BACKGROUND</b>The new Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation was developed to address the systematic underestimation of glomerular filtration rate (GFR) by the Modification of Diet in Renal Disease (MDRD) Study equation in patients with relatively well-preserved kidney function. Performance of the new equation in the Chinese population is unknown. The goal of the present study was to compare performance of these two equations in Chinese patients with chronic kidney disease (CKD).</p><p><b>METHODS</b>We enrolled 450 Chinese patients (239 women and 211 men) with CKD in the present study. The renal dynamic imaging method was used to measure the referenced standard GFR (rGFR) for comparison with estimations using the two equations. Their overall performance was assessed with the Bland-Altman method and receiver-operating characteristics (ROC) analysis. Performance of the two equations in lower and higher estimated GFR (eGFR) subgroups was further investigated.</p><p><b>RESULTS</b>Both eGFRs correlated well with rGFR (r = 0.88, 0.81, P < 0.05). In overall performance, the CKD-EPI equation showed less bias, higher precision and improved accuracy, and was better for detecting CKD. In the higher-eGFR subgroup, the CKD-EPI equation corrected the underestimation of GFR by the abbreviated MDRD equation.</p><p><b>CONCLUSIONS</b>The CKD-EPI equation outperformed the abbreviated MDRD equation not only in overall performance but also in the subgroups studied. For the present, the CKD-EPI equation appears to be the first-choice prediction equation for estimating GFR.</p>
