RESUMO

Objective: To explore the applied value of super-selective cervical lymph node dissection in papillary thyroid carcinoma (PTC) patients with clinically suspicious lateral lymph node metastasis (LNM). Methods: We retrospectively analyzed the clinical data of 232 cN1b PTC patients who underwent surgery from September 2013 to May 2018 in the Department of Head and Neck Surgical Oncology, National Cancer Center. Among them, 90 cases received super-selective neck dissection (level Ⅲ and IV) and 142 cases underwent selective neck dissection (level Ⅱ-Ⅳ). The LNM of two groups were analyzed. Results: Postoperative pathological results showed that 173 cases had LNM in the central compartment. The LNM cases of level Ⅱ-Ⅳ were 47, 147 and 130, respectively. Eight patients of super-selective neck dissection and 6 of selective neck dissection had postoperative lymphatic fistulas (P=0.146). No patients in super-selective neck dissection group while 9 patients in the selective lymph node dissection group had postoperatively permanent impairment of shoulder mobility, the difference was statistically significant (P=0.015). In the super-selective neck dissection group, 2 patients had long-term postoperative incision discomfort, and 5 cases had obvious cicatrix after surgery. In the patients with selective neck dissection, 27 cases experienced long-term incision discomfort after surgery, and 26 patients had apparent scar tissue, the differences were statistically significant (P<0.005). There was no recurrence during the follow-up. Conclusions: Super-selective neck dissection is a feasible, safe and effective treatment for cN1b PTC patients. It can improve the quality of postoperative life and avoid the over treatment for patients.

RESUMO

Exosomes are a kind of membrane vesicle with a diameter of 30-150 nm. It is formed by the budding of multiple vesicles in cells, which can fuse with the cell membrane and be released into the extracellular matrix. Adipose derived stem cells (ADSCs) have the potential of self-renewal and multi-directional differentiation. They can transport the active substance, regulate the inflammatory response, cell migration, proliferation, differentiation and angiogenesis via the action of paracrine exosomes, so as to enhance the ability of wound repair, promote wound healing, and inhibit the formation of scars. Chronic wounds refer to the wounds that can not reach the anatomic and functional integrity through the normal, orderly, and timely repair process, and the course of the wound healing is more than 4 weeks. At present, there are various treatment methods for chronic wounds, among which ADSCs, although showing a good application prospect, have some limitations due to ethical issues, while exosomes can avoid this problem. This article reviews the treatment of chronic wounds with ADSC exosomes.

RESUMO

OBJECTIVE: To investigate the changes of CaM-CaMK-CREB signaling pathway and related neuron factors in hippocampus of rats after sevoflurane and propofol administration. MATERIALS AND METHODS: A total of 90 SD rats, half male and half female, were selected. They were randomized into anesthesia group (AG) and control group (CG), in which 30 rats under propofol anesthesia in the AG were included in group A, 30 rats under sevoflurane anesthesia were included in group B, and 30 rats under mixed ventilation of air and oxygen were included in the CG. Before (10 rats were killed in each group) and at the end of anesthesia (2 weeks of anesthesia and 7 days of Morris water maze test), rats were respectively killed and then an appropriate amount of hippocampus was separated. Human tumor necrosis factor-alpha (TNF-α), vascular endothelial growth factor (VEGF), calmodulin (CaM), calmodulin-dependent kinase Ⅱ a (CaMK II a), NMDA receptor 2B (NR2B), cysteine aspartate specific protease-3 mRNA (Caspase-3mRNA) and protein contents were detected. RESULTS: The latency of rats in group A and group B, as well as their times of crossing the original platform on 1, 4, and 7d were markedly higher than those of the CG, and those in group B were markedly lower than those in group A (p<0.001). The total distance of rats in group A and group B on 1, 4, and 7d was significantly higher than that of the CG, and that in group B was dramatically lower than that in group A (p<0.001). The speed of rats in the three groups ranged from 1d to 7d, and there was no significant difference at different time points (p>0.05). At the end of anesthesia, the expression levels of CaM mRNA and protein in hippocampus of rats in group A and group B were remarkably higher than those of the CG, and those of CaMK II a mRNA and protein were remarkably lower than those of the CG; the CaM mRNA and protein expression levels in hippocampus of group A were significantly higher than those of group B, and those of CaMK IL a mRNA and protein were significantly lower than those of group B (p<0.001). Simultaneously, the expression levels of NR2BmRNA, Caspase-3mRNA and protein in hippocampus of group A and group B were substantially higher than those of the CG, and those in group B were substantially lower than those in group A (p<0.001). What's more, the TNF-a and VEGF expression levels in hippocampus of group A and B were markedly higher than those of the CG, and those in group B were dramatically lower than those of group A (p<0.001). CONCLUSIONS: Sevoflurane anesthesia on the CaM-CaMK-CREB signaling pathway and learning and memory function of rats is less volatile, which does better in safeguarding stability.

RESUMO

Objective: To discuss the safety and feasibility of transradial access (TRA) in performing peripheral arterial intervention. Methods: The clinical data of the patients underwent peripheral vascular intervention via TRA in our hospital from September 2017 to March 2019 were reviewed. The success rate of radial artery puncture and subsequent operation after puncture, and related postoperative complications within 30 days were analyzed. Results: The clinical data of 112 peripheral arterial intervention procedures via TRA performed on 106 patients were reviewed, including transcatheter arterial chemoembolization in 83 cases, bronchial arterial infusion in 4 cases, pelvic tumor embolization in 11 cases and 14 other cases. The success rate of all interventional punctures was 97.3% (109/112), the operative success rate of interventional procedures was 98.2% (107/109). The TRA operation was failed in 5 patients, who were then converted to receive the femoral artery puncture and complete successfully. The severe complication of the operation was aortic dissection (2 cases). Minor complications included 2 cases of radial artery occlusion, radial artery spasm, arm pain and puncture point hematoma for each case. The severe complication and the minor complication rates were 1.8% (2/112) and 4.5% (5/112), respectively. Sixteen emergency operations were performed successfully, and no complication occurred. Conclusion: The TRA is a clinically safe and feasible approach for peripheral arterial interventional procedure.

RESUMO

Objective: To evaluate and compare the quality of life (QOL) in patients with hypopharyngeal squamous cell carcinoma after laryngeal preservation surgery and total laryngectomy. Methods: We selected parts of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 and the Head and Neck Module (EORTC QLQ-C30 and EORTC QLQ-H&N35) and designed the QOL questionnaire. We investigated 42 patients with hypopharyngeal squamous cell carcinoma underwent laryngeal preservation surgery and 38 patients underwent total laryngectomy by QOL questionnaire and followed up their survival. Results: The somatic function dimension, psychological function dimension, and social function dimension of patients underwent laryngeal preservation surgery were (92.46±15.71), (80.56±22.67) and (90.08±19.50), respectively, which were higher than (79.39±32.75), (68.42±25.05) and (61.84±29.55) of the total laryngectomy group (P<0.05), while the economic dimension was not significantly different between the two groups (P>0.05). The social function dimension (including social support and socialization, family relationship) of laryngeal preservation surgery group were (89.04±25.47) for postoperative time < 70 months and (90.94±13.28) for postoperative time ≥70 months, which were higher than (65.48±29.14) and (57.35±30.32) of the total laryngectomy group (P<0.01). Conclusions: The somatic function dimension, psychological function and social function of patients with hypopharyngeal squamous cell carcinoma underwent laryngeal preservation surgery obtain a better QOL than patients underwent total laryngectomy. Therefore, we should improve the laryngeal function and QOL of patients under the premise of ensuring the survival rate.

RESUMO

OBJECTIVE: To investigate and analyse the clinical and immunological features of patients with myositis complicated with thromboembolism. METHODS: We identified a cohort of 390 myositis patients diagnosed with myositis admitted to People's Hospital of Peking University from 2003 to 2019. The patients were retrospectively enrolled in this investigation. According to the outcome of the color Doppler ultrasound, CT pulmonary angiography, pulmonary ventilation and perfusion scan patients were divided into myositis with and without thromboembolism group. Demographic, clinical (heliotrope rash, Gottron's sign/papules, periungual erythema, skin ulceration, subcutaneous calcinosis, Mechanic's hands, myalgia, interstitial lung disease, pulmonary arterial hypertension), laboratory, immunological [anti-autoantibodies including melanoma differentiation associated gene 5 (anti-MDA5), anti-Mi-2, anti-transcription intermediary factor-1γ (anti-TIF-1γ, anti-nuclear matrix protein 2 (anti-NXP2), anti-small ubiquitin-like modifier activating enzyme (anti-SAE), anti-synthetase], imaging and therapeutic status data of the patients at the diagnosis of myositis with and without thromboembolism were collected and the differences in these data were analyzed. Logistic regressive analysis was used to identify the risk factors of thromboembolism. RESULTS: In the retrospective study, 390 myositis patients were investigated. The mean age of onset was (49.6±13.4) years, male to female ratio was 0.31 :1. Thromboembolism was identified in 4.62% (18/390) of the myositis patients, which was lower than the published reports. Out of 18 patients with thromboembolism, 55.6% (10/18) of them were deep venous thrombosis, followed by cerebral infarction (22.2%, 4/18), pulmonary embolism (11.1%, 2/18), renal artery embolism (5.6%, 1/18) and embolism of upper extremity (5.6%, 1/18). Fifty percent of thromboembolism events occurred 6 months after the diagnosis of myositis, 38.9% of thromboembolism events occurred 6 months within the diagnosis of myositis, 11.1% of thromboembolism events occurred 6 months before the diagnosis of myositis. As compared with the myositis patients without thromboembolism, the myositis patients complicated with thromboembolism were older [(58.3±11.7) years vs. (49.3±13.4) years, P=0.006]. C-reaction protein (CRP) (12.2 mg/L vs. 4.1 mg/L, P < 0.001), ferritin (20 085.5 µg/L vs. 216.6 µg/L, P < 0.001) and D-dimer (529.0 µg/L vs. 268.0 µg/L, P=0.002) were significantly higher in thromboembolism group. Diabetes (44.4% vs. 16.4%, P=0.006), coronary heart disease (22.2% vs. 3.0%, P=0.003) and surgery (16.7% vs. 3.5%, P=0.032) were observed more common in thromboembolism group than those without thromboembolism. Activated partial thromboplastin time (APTT) (26.9 s vs. 28.7 s, P=0.049) and albumin (32.4 g/L vs. 36.5 g/L, P=0.002) was lower in thromboembolism group. The risk factors of thromboembolism in the myositis patients were low level of albumin (OR=0.831, 95%CI: 0.736-0.939, P=0.003), diabetes (OR=4.468, 95%CI: 1.382-14.448, P=0.012), and coronary heart disease (OR=22.079, 95%CI: 3.589-135.837, P=0.001) were independent significant risk factors for thromboembolism in the patients with myositis. There was no significant difference in clinical manifestations, myositis-specific antibodies or myositis-associated antibodies between the two groups. CONCLUSION: Thromboembolism is a complication of myositis. Lower levels of albumin, diabetes, and coronary heart disease might be risk factors of thromboembolism in myositis patients.

RESUMO

OBJECTIVE: To investigate the clinical features and outcome of hydronephrosis induced by retroperitoneal fibrosis (RPF), and to evaluate the effect of corticosteroid based therapy combined with surgical intervention of ureteral obstruction. METHODS: A total of 17 RPF patients with hydronephrosis hospitalized in Peking University International Hospital from May 2016 to December 2019 were analyzed retrospectively. RESULTS: The median age was 56 (53, 65) years, the male to female ratio was 2.4 : 1, and the disease duration was 4.00 (0.83, 8.00) months. The initial symptoms included back pain (9 cases), abdominal pain (6 cases), oliguria (2 cases) and lower limb edema (3 cases). Eight patients presented left hydronephrosis, 1 right hydronephrosis and 8 bilateral hydronephrosis. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were both elevated in 13 patients (76.5%, n=17). Immunoglobin (Ig) G4 increased in 5 cases (29.4%, n=17). IgG, IgE and IgA increased in 4 cases (30.8%, n=13), 4 cases (30.8%, n=13) and 1 case (7.7%, n=13), respectively. Among 12 patients who underwent biopsy, 3 patients were diagnosed with IgG4-relate disease. The level of IgG4 in the tissues varied, 6 cases expressed less than 10 per high power field (HPF) or no expression (50.0%). Only 2 cases expressed 10-30/HPF (16.7%), and 4 cases revealed more than 30/HPF (33.3%). Among the 17 patients with ureteral obstruction, no urinary drainage procedure was needed in 4 patients who had mild ureteral obstruction, whereas, ureteral stenting was carried out in the other 13 cases before drug treatment. Time was too short to evaluate the effect of urinary drainage procedures in 4 patients. For the rest, ureterolysis had to be performed in 3 cases after failed ureteral stent insertion. Successful drain removal was accomplished in all of these 9 patients and the mean time to drain removal was (6.7±3.0) months. In addition, 10 patients had complete medical records after an average follow-up time of 5 (3-13) months. Levels of ESR, CRP, IgG4, IgG, IgE, IgA were 54.0 (36.3, 98.5) mm/h, 26.8 (8.7, 53.0) mg/L, 1.34 (0.55, 3.36) g/L, 16.3 (13.0, 21.1) g/L, 40.5 (31.4, 203.0) IU/mL, 2.51 (1.82, 3.25) g/L at baseline, which all decreased predominantly after treatment. ESR, CRP, IgG4, IgG, IgE and IgA dropped by 38.5 (23.5, 54.3) mm/h (P < 0.01), 23.0 (5.5, 52.0) mg/L (P < 0.05), 0.92 (0.40, 2.85) g/L (P < 0.01), 6.5 (1.7, 9.1) g/L (P < 0.05), 23.7 (4.8, 162.0) IU/mL (P < 0.05) and 0.77 (0.32, 1.26) g/L (P < 0.05), respectively. Size of mass measured by CT/MRI imaging became smaller significantly and hydronephrosis relieved. CONCLUSION: Onset of RPF is insidious and lack of specific initial symptoms. Corticosteroid based therapy combined with surgical intervention of relieving obstruction is effective.

RESUMO

OBJECTIVE: To investigate the heterogeneity of decidual endothelial cells and their changes during delivery. PATIENTS AND METHODS: Single-cell RNA sequencing was used to characterize the transcriptomes of decidual endothelial cells before and after the onset of labor. RESULTS: Decidual endothelial cells (9748 cells) were divided into five subgroups with different functions according to differences in the transcriptome. The functions of cluster 5 were enriched in vascular development and response to growth factors. After the onset of labor, the activities of each cluster were different, including the interleukin 17 pathway and regulation of ERK1 and ERK2 cascade. The downregulated genes were related to scavenger receptor (cluster 5), which may reflect the process of endothelial activation. In terms of genetic changes, cluster 5 may be more actively involved in labor than the other clusters. CONCLUSIONS: Peripartum decidual endothelial cells are heterogeneous and participate in labor to varying degrees. One of the five subtypes of endothelial cells may be more actively involved in labor onset. Our findings may enable the assessment of decidual endothelial cells and labor onset.

RESUMO

OBJECTIVE: To measure the level of serum Semaphorin 3A (Sema3A) and to analyze the relationship between serum Sema3A and systemic lupus erythematosus (SLE) with thrombocytopenia. METHODS: The concentration of serum Sema3A was detected by enzyme-linked immuno sorbent assay (ELISA) in 170 SLE patients, 50 Sjögren's syndrome (SS) patients, 19 hypersplenism (HS) patients and 150 healthy controls (HC). Based on the presence of thrombocytopenia and whether the thrombocytopenia was in remission, the SLE patients were divided into three groups: SLE with thrombocytopenia (41 cases), SLE with thrombocytopenia remission (28 cases), and SLE without thrombocytopenia (101 cases). According to whether there was thrombocytopenia, the SS patients were divided into SS with thrombocytopenia (18 cases) and SS without thrombocytopenia (32 cases). The 28 SLE patients who underwent bone marrow aspiration biopsy were divided into two groups from the aspect of whether the bone marrow hyperplasia was normal (19 cases) or low (9 cases), as well as from the aspect of whether the maturity disturbance of megakaryocyte was positive (8 cases) or negative (20 cases). The serum Sema3A levels in SLE, SS, HS with HC were compared, meanwhile, the correlation between serum Sema3A level and platelet (PLT) in the patients with different diseases analyzed. RESULTS: (1) Serum Sema3A levels in SLE were significantly lower than in HC [(3.84±2.76) µg/L vs. (6.96±2.62) µg/L, P < 0.001], serum Sema3A levels in SS were also obviously lower than in HC [(4.35±3.57) µg/L vs. (6.96±2.62) µg/L, P < 0.001], and in HS it was lower than HC at a certain extant [(5.67±2.26) µg/L vs. (6.96±2.62) µg/L, P=0.041]. (2) Serum Sema3A levels in SLE were slightly lower than in SS, but there was no significant difference [(3.84±2.76) µg/L vs. (4.35±3.57) µg/L, P=0.282]. However, when compared with HS, serum Sema3A levels in SLE were significantly lower [(3.84±2.76) µg/L vs. (5.67±2.26) µg/L, P=0.006]. (3) Serum Sema3A concentration in SLE with thrombocytopenia was significantly lower than in SLE with thrombocytopenia remission [(1.28±1.06) µg/L vs. (3.83±2.65) µg/L, P < 0.001], and in SLE patients without thrombocytopenia [(1.28±1.06) µg/L vs. (4.87±2.60) µg/L, P < 0.001]. There was no significant difference between SLE with thrombocytopenia remission and SLE without thrombocytopenia [(3.83±2.65) µg/L vs. (4.87±2.600 µg/L, P=0.123]. Serum Sema3A concentration in SLE with thrombocytopenia was slightly lower than in SS with thrombocytopenia, but there was no significant difference [(1.28±1.06) µg/L vs. (1.68±1.11) µg/L, P=0.189]. (4) Strong positive correlations were found between serum Sema3A and PLT in SLE (r=0.600, P < 0.001). Positive correlations were also found between serum Sema3A and PLT in SS (r=0.573, P < 0.001). However, there was no such correlation showed in HS patients (P=0.393). (5) There was no significant difference of serum Sema3A concentration in SLE whether the bone marrow hyperplasia was normal or low. And the same situation appeared in the patients whether the maturity disturbance of megakaryocyte was positive or negative (P>0.05). CONCLUSION: Serum Sema3A was significantly reduced in SLE patients, and it was highly correlated with the blood damage. Similar conclusions could be drawn in patients with SS. The serum level of Sema3A was generally decreasing in desmosis which merged thrombocytopenia, and was obviously positive correlated with platelet counts.

RESUMO

OBJECTIVE: To evaluate decision regret among patients receiving penile girth enhancement with acellular dermal matrix (PGE with ADM) and to investigate the potential indicators for decisional regret so as to facilitate the decision-making process for this special group. METHODS: In the study, 78 patients receiving PGE with ADM from Jun. 2016 to Jan. 2019 at Peking University People's Hospital and cooperative hospitals were eligible. Penile girth was taken by only one surgeon 1 week before surgery. Hospital anxiety and depression scale (HAD), international index of erectile function (IIEF) and a 10 cm long visual analogue scale named visualized penile image (VPI) were applied to measure psychological burden, erectile function and satisfaction with penile image respectively at the same time. All the patients were followed up for 3 months. Decision regret scale (DRS) was adopted for measuring decisional regret. Multivariate analysis of variance was applied to investigate the potential indicators for regret. Data analysis process was conducted with SPSS (version 24.0; SPSS, Chicago, IL, USA). RESULTS: Mean penile girth recorded before intervention was (8.29±0.30) cm and increased to (9.46±0.29) cm post surgery (t=76.28, P < 0.01). As for both subscales of HAD measuring psychological burden, a signi-ficant reduction in the mean score was seen, that is, 2.8±1.3 (t=19.28, P < 0.05) for anxiety and 3.0±1.2 (t=20.67, P < 0.05) for depression, respectively. The average score of VPI increased by 3.7±1.1 (t=30.63, P < 0.05). There was no significant change in the average score of IIEF measuring erectile satisfaction (t=1.60, P=0.11). Twenty-nine (38.2%) patients expressed regret to some degree, and the mean DRS score was 23.4±14.8. The scores of DRS correlated negatively with scores of visualized penis image (r=-0.348, P < 0.01), and positively with scores of anxiety (r=0.760, P < 0.01) and depression subscale (r=0.471, P < 0.01). The scores of DRS was irrelevant to those of IIEF (r=0.02, P=0.867). The patients with high annual income (> 120 000 yuan) and education level above undergraduate were more prone to experience decision regret after intervention (P < 0.01). CONCLUSION: PGE with ADM did augment penile girth and lower psychological burden, the regret rate of which was acceptably low among the patients. High income and good education might indicate more post-operative regret. Additional decision-making aids should be offered to patients with high income and education level above high school.

RESUMO

Objective: To systematically evaluate the safety and efficacy of dexmedetomidine combined with ketamine during dressing changes in burn patients using meta-analysis. Methods: Foreign language databases including PubMed, Cochrane Central, Embase, and Web of Science were searched with the terms of " burns, dexmedetomidine, ketamine, and dressing" , and Chinese databases including Chinese Journal Full-Text Database, Wanfang Data, and China Academic Journal Network Publishing Database were searched with the terms in Chinese version of ",,,,," to retrieve the publicly published randomized controlled trials on the application of dexmedetomidine combined with ketamine for sedation and analgesia during dressing changes in burn patients from the establishment of each database to March 2019. The outcome indexes included systolic blood pressure at 5 minutes after administration, arousal restlessness score, ketamine dosage, dressing change time, body movement/recovery time, pain score, Ramsay sedation scores at 10 minutes after the start of dressing change and 1 hour after dressing change, physician satisfaction score, neuropsychological symptoms, nausea and vomiting times, nausea and vomiting score. RevMan 5.3 and Stata 14.0 statistical software were used to conduct a meta-analysis of eligible studies. Results: A total of 396 burn patients were included in 7 articles, including 198 patients in dexmedetomidine+ ketamine group who received dexmedetomidine and ketamine for sedation and analgesia, and 198 patients in ketamine alone group who received ketamine alone for sedation and analgesia. The bias risks of the seven studies included were uncertain. Compared with those of ketamine alone group, the systolic blood pressure at 5 minutes after administration, arousal restlessness score, nausea and vomiting score of patients in dexmedetomidine+ ketamine group were significantly decreased, with standardized mean differences of -13.89, -0.84, and -0.99 (95% confidence interval=-20.89--6.89, -1.17--0.52, -1.31--0.68, P<0.01), the Ramsay sedation score at 10 minutes after the start of dressing change and that at 1 hour after dressing change were significantly increased, with standardized mean differences of 1.53 and 0.72 (95% confidence interval=1.05-2.02, 0.13-1.31, P<0.05 or P<0.01), and the number of neuropsychological symptom and number of nausea and vomiting were significantly reduced, with relative risks of 0.20 and 0.16 (95% confidence interval=0.07-0.58, 0.05-0.58, P<0.01). The patients in the two groups were similar in ketamine dosage, dressing change time, body movement/recovery time, pain score, and physician satisfaction score. There was no publication bias in dressing change time or ketamine dosage (P>0.05), while the other indexes might have publication bias (P<0.05). Conclusions: Compared with ketamine alone, combination of dexmedetomidine and ketamine during dressing changes in burn patients can reduce the occurrence of restlessness, nausea and vomiting, neuropsychological symptoms, and other complications, better stabilize blood pressure, and enhance sedation effect.

RESUMO

Objective: To investigate the expression of CD8(+)CD25(+)T cells in peripheral blood of patients with rheumatoid arthritis (RA) and its correlation with clinical indicators of rheumatoid arthritis. Methods: Peripheral blood was collected from 38 patients with RA, and 20 healthy control subjects, RA patients admitted to Peking University people's hospital from May to October 2018, and record the RA patients with the clinical manifestations and laboratory indexes, extraction in the peripheral blood lymphocytes, using flow cytometry to analyse the percentage of CD8(+)CD25(+)T cells in peripheral blood, by using the software SPASS20 and Prism6 to analyze its correlation with clinical and laboratory indices. Results: The expression of CD8(+)CD25(+)T cells in peripheral blood of RA patients was significantly increased, which was statistically different from that of healthy patients (P<0.05). CD8(+)CD25(+)T cells in peripheral blood of RA patients showed significant positive correlation with ESR(r=0.352,P=0.030), CCP(r=0.312,P=0.047) and DAS28(r=0.330,P=0.043), and negatively correlated with C3 (r=-0.354,P=0.046) and C4(r=-0.440,P=0.010).No significant correlation was found in other indicators. In RA patients, there were statistically significant differences in CD8(+)CD25(+)T cells between the low-disease active group and the high-disease active group(P<0.05), but CD8(+)CD25(+)T cells between the low-disease active group and the moderate-disease active group, or between the moderate-disease active group and the high-disease active group had no significant statistical difference. Conclusion: CD8(+)CD25(+)Tcells in peripheral blood of patients with RA are significantlyincreased, and aresignificantly correlated with laboratory and clinical indicators, which may play an important role in the pathogenesis of rheumatoid arthritis.

RESUMO

Objective: To explore the correlation between Semaphorin 4D (Sema4D) and rheumatoid arthritis (RA) clinical manifestations, laboratory indexes, bone destruction and rheumatoid arthritis related interstitial lung disease(RA-ILD), and to analyze its significance in evaluating the severity of patients with rheumatoid arthritis. Methods: A total of 108 RA patients and 50 healthy controls from September 2018 to October 2019 were collected from the Department of Rheumatology and Immunology, Peking University People's Hospital and Beijing Haidian Hospital. According to the DAS 28 score, RA patients were divided into active disease group (DAS28>2.6) and stable disease group (DAS28 ≤ 2.6). Fifty healthy controls. The levels of Sema4D in serum were detected by enzyme-linked immunoassay method (ELISA), and their correlation with clinical manifestations of RA, laboratory indicators, degree of bone damage and RA-ILD were analyzed. Results: The level of serum Sema4D in RA active group was significantly higher than that in stable group and healthy control group (P<0.05). The concentration serum Sema4D was positively correlated with C-reactive protein(CRP) (r=0.28, P<0.05), rheumatoid factor(RF) (r=0.25, P<0.05) and the 28-joint disease activity score (DAS28) (r=0.45, P<0.01). The concentration serum Sema4D was positively correlated with ß-Crosslaps(r=0.20, P<0.05) and Sharp-van der Heijde score (SHS)(r=0.13, P<0.05). The concentration serum Sema4D was positively correlated with Vascular endothelial growth factor (VEGF)(r=0.25, P<0.05) and Warrick score of chest CT in RA patients(r=0.27, P<0.05). The anti-cyclic citrullinated peptid(CCP) antibody, DAS28, VEGF and the incidence of RA-ILD were significantly higher than that in Sema4D negative group (P<0.05). Conclusions: Serum Sema4D level in RA patients is closely related to the disease activity, bone destruction and RA-ILD. Serum Sema4D can be used as an indicator of disease monitoring and prognosis evaluation in RA patients.

RESUMO

Objective: To explore the role and mechanism of aging pathway in patent ductus arteriosus closure of rats. Methods: Thirty outbreeding Sprague Dawley rats(20 females, 10-15 weeks old, 270-330 g) underwent random mating and conception. The primary Ductus Arteriosus smooth muscle cells (DASMCs) of pregnant 19 days(E19 group), 21 days(E21 group) and newborn(Day0 group) fetus were extracted and cultured. mRNA expression of cell senescence related markers p16, 21 and 53 genes in each group were detected by real-time fluorescent quantitative PCR(RT-PCR) after 48 hours culture. After hypoxic culture on DASMCs for 3 days, the DASMCs were divided into 3 groups: hypoxic control group(G0 group), 3 hours normal oxygen concentration treatment group(G3 group) and 6 hours normal oxygen concentration treatment group(G6 group). After intervention, mRNA expression of p16, 21 and 53 RT-PCR was detected. The DASMCs of newborn rats(Day0 group) were extracted and divided into 3 groups:low-oxygen culture control group, low-oxygen+siRNA culture group and normal oxygen concentration culture group. The DASMCs migration ability was tested experimentally by Transwell method. Result: The mRNA levels of p16, 21 and 53 in DASMCs were higher in E19 group than in Day0 group(all P<0.01), and the mRNA levels of p16, 21 and 53 in DASMCs were also higher in E21 group than those in Day0 group (all P<0.01). The mRNA levels of p16, 21 and 53 in DASMC were all higher in G0 group than those in G3 group (P<0.05 or 0.01), and the mRNA levels of p16, 21 and 53 in DASMCs were all higher in G0 group than those in G6 group (all P<0.01), and the mRNA levels of p16, 21 and 53 in DASMCs were all higher in G3 group than those in G6 group (all P<0.05). DASMCs migration ability of newborn rats was higher in normal oxygen concentration culture group than that in low-oxygen culture group (P<0.01), and DASMCs migration ability of newborn rats was also higher in low-oxygen+siRNA culture group than that in low-oxygen culture group (P<0.01). Conclusion: The expression of senescence marker of DASMCs decreases with the birth in rats during the process of ductal closure, and the aging pathway may affect ductal closure by inhibiting DASMCs migration in rats.

RESUMO

Objective: The aim of present study is to analyze clinical and laboratory features of mixed connective tissue disease (MCTD)-associated trigeminal neuropathy (TN). Methods: Clinical records of 12 cases of MCTD complicated with TN diagnosed in Peking University People's Hospital from January 2008 to October 2019 were analyzed retrospectively. Results: The present study included 12 cases, 1 males and 11 females, average age was(40±13)years. TN was developed before the diagosis of MCTD in 1 case. TN and MCTD were occurred simutaneously in 1 case. Raynaud phenomenon (12 cases), arthritis (10cases), edema of fingers (9cases), myositis (6 cases), and pulmonary involvement (11cases) were main cinical feature of MCTD-associate TN. Antinuclear antibody (ANA) and high titer anti-U1-RNP antibody could be detected in serum of all patients. Elevated erythrocyte sedimentation rate (ESR) and creatine kinase were found in serum of 7cases and 5cases, respectively. Blink reflex tests were positive in 6 cases. Neurological symptoms improve slowly without any progress by using glucocorticoid combined immunosuppressants or intravenous gamma globulin. Conclusions: TN is often associted with actived MCTD. Positive ANA and anti-U1-RNP antibody were common in MCTD-associated TN. Blink reflex test is essential to diagnose MCTD-associated TN. Intensive treatment of MCTD contributes to control the progress of TN.

RESUMO

Objective: To investigate the clinical and immunological features of cardiac involvement in patients with dermatomyositis (DM). Methods: Data of 271 adult patients with DM diagnosed in the Department of Rheumatology and Immunology, Peking University People's Hospital from 2003 to 2018 were collected retrospectively and analyzed statistically. Results: The occurrence of cardiac involvement in DM was 15.9% (43/271). Main feature of cardiac involvement in DM was elevated cardiac troponin I (cTnI). The most common abnormalities of ECG were T wave abnormality (27.9%, 12/43), sinus tachycardia (16.3%,7/43), ST-T change (14%, 6/43) and right bundle branch block (7%, 3/43). The common manifestations of echocardiography were left ventricular diastolic dysfunction (23.3%, 10/43) and pericardial effusion (23.3%, 10/43). As compared with DM patients without cardiac involvement, DM patients with cardiac damage were more likely to have rapidly progressive interstitial lung disease (ILD), skin damage, anemia, elevated creatine kinase, decreased C3 and serum albumin (P<0.05). Positive anti-Ro-52 antibody and Jo-1 antibody were detected more common in DM with cardiac involvement(P<0.05). Conclusions: Cardiac damage is common complication of DM. Manifestations of cardiac damaging are varied. Rapid progressive ILD and positive Jo-1 and Ro-52 antibodies are more common in this group. Clinicians should improve the awareness of cardiac involvement in DM patients.

RESUMO

OBJECTIVE: To detect the levels of Dickkopf-1 (DKK-1) in the plasma of patients with rheumatoid arthritis (RA), and to analyze their correlation with peripheral blood T cell subsets and clinical indicators. METHODS: Enzyme-linked immunosorbent assay (ELISA) was used to detect plasma DKK-1 levels in 32 RA patients and 20 healthy controls, and to record the various clinical manifestations and laboratory indicators of the RA patients, and flow cytometry to detect peripheral blood T cell subsets in the RA patients (Including Treg, nTreg, aTreg, sTreg, Teff, Tfh, CD4+CD161+T, CD8+T, CD8+CD161+T cells). The plasma DKK-1 levels between the two groups were ompared, and its correlation with peripheral blood T cell subsets and clinical indicators analyzed. RESULTS: (1) The plasma DKK-1 concentration of the RA patients was (124.97±64.98) ng/L. The plasma DKK-1 concentration of the healthy control group was (84.95±13.74) ng/L. The plasma DKK-1 level of the RA patients was significantly higher than that of the healthy control group (P < 0.05), and the percentage of CD8+CD161+T cells in the peripheral blood of the RA patients was significantly higher than that of the healthy control group (P < 0.05). (2) The plasma DKK-1 level was positively correlated with erythrocyte sedimentation rate (r=0.406, P=0.021), DAS28 score (r=0.372, P=0.036), immunoglobulin G(r=0.362, P=0.042), immunoglobulin A(r=0.377, P=0.033); it had no correlation with age, course of disease, C-reactive protein, rheumatoid factor, anti-cyclic citrullinated peptide antibody, immunoglobulin M, complement C3, complement C4, white blood cell, neutrophil ratio. (3) The plasma DKK-1 level in the RA patients was positively correlated with the percentage of peripheral blood CD161+CD8+T cells (r=0.413, P=0.019);it had no correlation with Treg, nTreg, aTreg, sTreg, Teff, Tfh, CD4+CD161+T, CD8+T cells. (4) The percentage of CD161+CD8+T cells was negatively correlated with erythrocyte sedimentation rate (r=-0.415, P=0.004), C-reactive protein (r=-0.393, P=0.007), DAS28 score(r=-0.392, P=0.007), rheumatoid factor (r=-0.535, P < 0.001), anti-citrullinated protein antibody (r=-0.589, P < 0.001), immunoglobulin G(r=-0.368, P=0.012) immunoglobulin M (r=-0.311, P=0.035); it had no correlation with age, disease course, immunoglobulin A, complement C3, complement C4, white blood cell, and neutrophil ratio. CONCLUSION: RA patients' plasma DKK-1 levels and the percentage of CD8+CD161+T cells in T cell subsets in peripheral blood increase, which may be related to the secretion of proinflammatory cytokines in patients; DKK-1 is involved in the regulation of bone homeostasis and can be used as a marker of bone destruction in RA.
