Objective: To evaluate the efficacy and side effects of tocilizumab for the treatment of systemic juvenile idiopathic arthritis. Method: In this prospective self case-control study, the children diagnosed with refractory systemic juvenile idiopathic arthritis admitted to Department of Rheumatism and Immunology of Children's Hospital Affiliated to Capital Institute of Pediatrics from December 2013 to June 2016 were enrolled and information before and after treatment of tocilizumab was analyzed. The tocilizumab was introvenously guttae in a dose of 8-12 mg/kg every 2 weeks. Complete blood count, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were tested before and after the application of tocilizumab. Detailed clinical manifestations were recorded. All results were analyzed by χ² test and t test. Result: Forty patients with a median age of (6.6±3.7) years were enrolled, including 15 males and 25 females. All of the patients presented with fever and 38 patients got normal temperature 24-48 hours after treatment with tocilizumab. Symptoms disappeared in 13 and improved in 4 patients after treatment among the 17 patients who presented with arthritis. Within the 10 patients who manifested with rashes, 9 patients' rashes disappeared without relapse accompanied by the normalization of temperature after the treatment of tocilizumab. One patient got normal temperature but intermittently emerged rashes after symptoms of arthritis improved. In the 40 patients, 38 well tolerated tocilizumab while 2 showed rashes and chill which disappeared shortly after antianaphylaxis treatment. No severe treatment-related infection was found in any patients. According to the study, the white blood cell counts(×10⁹/L), CRP(mg/L) and ESR(mm/1h) tested 2 weeks after the treatment with tocilizumab were significantly lower than that before treatment(12.1±1.2 vs. 16.5±1.8, 47±8 vs. 67±9, 21±5 vs. 57±6, t=2.75, 3.98, 5.22, P=0.009, 0, 0, respectively). No significant changes were found in concentration of IL-6 and TNF-α (65(207) vs. 45(137) ng/L, and 14(6) vs. 17(19)ng/L, Z=-1.247 and-1.285, P=0.212 and 0.199 respectively). Conclusion Tocilizumab is a treatment with good efficacy and safety for refractory systemic juvenile idiopathic arthritis. Adverse effects would be found in some patients.

Objective: To summarize the clinical data of 15 patients with fibrodysplasia ossificans progressiva (FOP), follow up and analyze the characteristics of the joint involvement in FOP. Method: From May 2005 to December 2016, fifteen FOP cases had been diagnosed in the Children′s Hospital Capital Institute of Pediatrics. All medical records and follow-up data were collected and a retrospective analysis was made on the joint involvement in FOP. Pearson correlation analysis was used for data, P<0.05 for the difference was statistically significant. Result: There were 8 males and 7 females in 15 cases. The age of onset was 2(1-6)years. The age at diagnosis was 6 (4-9) years. All cases had hallux valgus deformity and bone mass formation. Twelve cases had joints involvement on enrollment into this study: 8 cervical vertebra, 7 shoulder joint, 5 hip joint, 4 elbow joint, 3 wrist joint, 2 temporomandibular joint, 2 lumbar vertebra. The age of diagnosis and duration of disease were positively correlated with the number of the involved joints (r=0.523, 0.628; P=0.045, 0.012); mild changes were found in joint imaging. Thirteen cases received telephone follow-up, the average duration of follow-up was 6(3-7)years, no change in 11 cases, disease progress in 2 cases. Conclusion Joint involvement is a common complication of FOP, especially the cervical vertebra.Multiple joints involvement, dominant functional impairment, and mild imaging changes are the characteristics of joint lesions caused by FOP.The number of involved joints gradually increases with increase of age of the patients and the prolonged course of the disease.

Objective To investigate the clinical treatment strategy of large and giant pituitary adenomas invading the cavernous sinus.Methods One hundred and nine patients with large and giant pituitary adenomas invading the cavernous sinus,admitted to our hospital from January 2010 to December 2018,were chosen in our study.Four patients with prolactin-type pituitary adenomas received oral treatment with bromocriptine;the remaining 105 patients received surgical treatment,and choices of surgical approach were based on classification of pituitary adenomas.The clinical data and efficacies of these patients accepted different treatment approach were retrospectively analyzed.Results Of the 105 patients with pituitary adenomas,63 (60％) were of type Ⅰ,15 (14.3％) were of type Ⅱ,18 (17.1％)were of type Ⅲ,and 9 (8.6％) were of type Ⅳ.Single extended transsphenoidal approach was used in 75 patients,transcranial approach was used in 26 patients,and combined extended transsphenoidal and transcranial approach was used in 4 patients.Gross total tumor resection was achieved in 86 patients,subtotal resection in 17 patients,and partial resection in two patients.Ten patients had new cranial nerve palsy after surgery,including 7 with oculomotor nerve palsy and three with abductor nerve palsy;two patients with preoperative neurological paralysis were aggravated,and both of them were oculomotor nerves;transient insipidus was noted in 19 patients and electrolyte disorder was noted in 23 patients;no permanent insipidus,cerebrospinal fluid leakage or intracranial infection,and no new or aggravated visual field vision disorder were noted.Conclusion Reasonable clinical treatment strategies and appropriate microsurgical approaches can achieve good therapeutic effect in patients with large and giant pituitary adenomas invading the cavernous sinus.

Objective:To summarize the clinical characteristics of children with rheumatic disease combined with endocrine disorder.Methods:A retrospective analysis was performed on the clinical data, including sex, age, clinical presentation, laboratory tests, treatment and outcome, of 13 patients with rheumatic diseases combined with endocrine disorder, who were admitted to our department in Children′s Hospital, Capital Institute of Pediatrics from January 2014 to December 2020.Results:Among the 13 cases, 3 were males and 10 were females, without family history. Their age was (10±4) years. And the average course of disease was 4.1 months. Eight of them were diagnosed with systemic lupus erythematosus (JSLE), 2 with juvenile idiopathic arthritis (JIA), 1 with childhood vasculitis, 1 with juvenile-onset systemic sclerosis (JSSc) and 1 had juvenile dermatomyositis (JDM). Regarding the initial presentation, 10 cases had symptoms of rheumatic disease, 2 had polydipsia and polyuria, and 1 had goiter. All the 13 patients had multiple system involvement. Regarding endocrine disorder, 10 had thyroiditis or subclinical thyroiditis, 4 had diabetes mellitus and one had both thyroid and pancreas involvement. Thyroid stimulating hormone in 10 patient with thyroid involvment was 19.6 (5.2-34.0) mU/L, and their total thyroxine was 75.3 (45.2-105.4) nmol/L. Besides, thyroid peroxidase antibody or thyroglobulin antibody was positive in 7 cases. The blood glucose of 4 children with pancreatic injury was 25.0 (17.0-33.0) mmol/L, and C-peptide was 0.4 (0.3-0.5) mg/L. Glutamate dehydrogenase antibody, protein tyrosine phosphatase antibody and zinc transporter 8 antibody were positive in two cases. After treatement with immunosuppressant or immunoglobulin combined with glucocorticoid or nonsteroidal antiinflammatory drugs for rheumatic symptoms, and levothyroxine or insulin for endocrine diseases, they were all followed up for more than 6 months and maintained clinical stability.Conclusions:Rheumatic diseases in children can be complicated with endocrine disorders, and the involved organs are usually thyroid and pancreas. In children with rheumatic disease, thyroid injury usually has subtle onset, whereas pancreas injury develops rapidly, even life-threatening. Insulin should be used persistently under the instruction of endocrinologist.

Objective:To summarize the clinical features of 14 cases with clinically and genetically diagnosed progressive pseudorheumatoid dysplasia(PPRD) and analyze the characteristics of joint lesions caused by PPRD to provide references for clinical diagnosis and treatment of PPRD.Methods:A retrospective analysis was made on the clinical data and genetic test data of 14 patients admitted to Children′s Hospital, Capital Institute of Pediatrics and cooperative units, from December 2017 to September 2023.An observational retrospective analysis was performed on hospitalization and follow-up data, and correlation factors were analyzed using the Kendall correlation test.Results:The 14 patients, including 6 males and 8 females, were all Chinese Han children.The average age of onset was 6.12 years(2-11 years), the average age of diagnosis was 10.61 years old(5-17 years old), and the average duration of the disease was 4.46 years(0.5-6.0 years) at diagnosis.The number of joint involvements ranged from 4 to 14, with an average of 9.20.There were 12 patients with claudication as the first symptom.All these 14 children had limited hip mobility and no obvious hip pain.The hip joint imaging indicated that space narrowing occurred in 11 cases, femoral neck shortening in 2 cases, femoral head displacement in 4 cases, and articular surface sclerosis, cystic degeneration or bone destruction in 8 cases.The joints of the four limbs were mainly manifested as enlargement of the proximal interphalangeal joints and metacarpophalangeal joints of both hands.The other joints were knees(11 cases), elbows(8 cases), wrists(7 cases) and ankles(5 cases) in the order of easy involvement, and the shoulder joint was less involved(1 case).The spine was mainly characterized by changes in the curvature, and limited movement was found in 8 cases.Thoracic and lumbar spines were mainly involved(13 cases), while cervical involvement was rare(1 case).The duration of the disease at diagnosis was positively correlated with the number of joint involvements and the number of joint mobility limitations( r=0.584, 0.671; P=0.007, 0.002).In this study, 8 children were misdiagnosed as juvenile idiopathic arthritis, and the longest misdiagnosis time was 6 years.All the 14 children had CCN6 gene mutations, including 10 complex heterozygous mutations and 4 homozygous mutations.Five children had c. 342T>G and c. 667T>G, 4 children had c. 589 + 2(IVS4)T>C, 3 children had c. 866dup, and 2 children had c. 136C>T and c. 624dupA. Conclusions:PPRD is characterized by multiple joint involvements, among which hip involvement is the most common.The lesions are serious and easily misdiagnosed as juvenile idiopathic arthritis.The number of affected joints increases gradually with the prolongation of the disease course.

Objective: To evaluate the value of serum cytokine level in the efficacy of tocilizumab for the treatment of systemic-onset juvenile idiopathic arthritis. Methods: 30 cases with SoJIA hospitalized in Capital Institute of Paediatrics from June 2016 to October 2018 were treated with Interleukin-6 receptor antagonist(tocilizumab) injection. Among them, 20 were males(67%) and 10 were females(33%). The age at diagnosis was between 0.84 to 13years. Whiteblood cell, C-reactive protein, erythrocyte sedimentation rate, serum interleukin(IL-6, IL-2R, IL-8, IL-10, IL-1β) and tumor necrosis factor-alpha levels were observed before treatment, after the 2nd week, after the 6th week and after the 22nd week.Mann-Whitney nonparametric test and Chi-square test were used to analyze the data of cytokines pre and after-treatment. Results: All of the 30 cases had fever before medication. The fever disappeared in 28 cases after using tocilizumab. One case stopped using tocilizumab because of allergic reaction and one case stopped because of poor efficacy. Among 28 cases with normal body temperature after medication, the arthritis and rash manifestations were significantly improved. WBC, AESR and CRP were all lower than those before medication. Within these 28 cases, the serum IL-6 level was168.50(67.40-589.25) pg/mL pre-treatment, 107.50(28.03-281.50) pg/mL after the 2nd week. There was no statistical difference between them(Z=-1.754, P>0.05). The serum IL-6 level was 64.05 (19.90-130.75) pg/mL after the 6th week and 24.80 (3.45-95.40) pg/mL after the 22nd week. Compared with pre-treatment, they were all lower than pre-treatment levels(Z=-2.942,-3.334,P<0.01,<0.01).Serum IL-2R level was 740.50(510.00-1 161.00)U/mL after the 2nd week, 796.50 (534.00-1 008.00) U/mL after the 6th week and 688.00 (527.00-889.50) U/mL after the 22nd week. Compared with pre-treatment [1 322.50(812.00-1 659.00)U/mL], they were all lower than pre-treatment levels (Z=-2.818,-3.130,-3.466, P<0.01, <0.01, <0.01). Serum TNF-alpha level was 23.70 (20.30-41.23) pg/ml after the 2nd week, 26.75(16.83-47.03) pg/ml after the 6th week,18.60(13.10-34.90) pg/ml after the 22nd week. Compared with pre-treatment [26.50(20.55-37.43) pg/ml], there were no statistical difference between after and pre-treatment(Z=0,-0.560,-1.954,P>0.05,>0.05,>0.05). Serum IL-8 level was 200.85(95.43-364.00)pg/ml after the 2nd week, 194.50(50.75-433.00)pg/ml after the 6th week, 161.50 (38.98-308.00)pg/ml after the 22nd week. Compared with pre-treatment [96.20(59.75-371.75) pg/ml], there were no statistical difference between after and pre-treatment(Z=-0.86,-0.131,-0.186,P>0.05,>0.05,>0.05). There was no statistical difference between after the 2nd week and pre-treatment in the IL-10 level(χ²=2.33, P>0.05). The IL-10 level after 6th week and after 22nd week were all lower than pre-treatment levels(χ²=4.08, 4.08, P<0.05, <0.05). There were no statistical difference between after and pre-treatment(χ²=0.084, 2.504,3.818,P>0.05,>0.05,>0.05)in IL-1β level. Conclusion After treatment with tocilizumab, the levels of serum IL-6 and IL-2R are helpful to assess the activity of SoJIA and the efficacy of therapy.

Narrative is the cornerstone of interpersonal relationships and life safety. However， its important value in daily life， school education， health management， personal happiness， career development， and other aspects has been ignored. The narrative ecology of families， schools， hospitals， workplaces， and elderly care institutions is worrying， the narrative connection between parent-child and intergenerational is broken， the narrative nature of adolescents is ignored， the narrative demands of patients are neglected， narrative relationships in the workplace are indifferent， and the narrative capital of the elderly is idle. These issues have resulted in serious social problems， such as depression and suicide among adolescents， conflicts between doctors and patients， workplace and life burnout among middle-aged people， and the inability of the elderly to achieve healthy aging， which have become a “stumbling block” to the realization of holistic health. Advocating the construction of narrative ecology and interpersonal narrative connections is an important measure of achieving holistic health. Taking the “narrative concept” as the overall framework， and based on the research， education， and practice carried out by the Alliance of Narrative Medicine in Higher Education Institutions， this paper proposed that actively build China’s narrative system of life and health， to enable narrative play an active and dynamic role in the construction of narrative ecology in different spaces， such as the families， the schools， the hospitals， the workplaces， and the elderly care institutions， as well as practically improve the quality of life of the people.

Objective: To investigate the early typing diagnostic and predictive value of anti-keratin antibodies(AKA), anti-perinuclear factor(APF) and anti-citrullinated protein antibodies(ACPA) in patients of juvenile idiopathic arthritis (JIA). Methods: A retrospective study was conducted to collect 144 cases of JIA who were hospitalized in Capital Institute of Pediatrics from December 2013 to June 2016 and followed up for at least one year.Among them,66 were males (46%) and 78 were females (54%).The age at diagnosis was between 1 year 5 months to 15 years 9 months.144 patients were tested for AKA,ACPA,APF and TNFα upon admission. Chi-square test or Fisher exact test were used to compare the positive rates of three antibodies among different subtypes. Mann-Whitney nonparametric test and Chi-square test or Fisher exact test were used to analyze the data of prognosis between antibody-positive group and antibody-negative group in the course of disease. Results: In 144 patients, 49(34%) were classified as systemic arthritis, 28 (19.4%) as polyarthritis, 61(42.3%) as oligoarthritis, and 6(4.2%) as enthesitis-associated arthritis. 52 cases (36.1%) were positive for one antibody or more antibodies of AKA/APF/ACPA at the early stage, 14(9.7%) were AKA positive, 44(30.6%) were ACPA positive and 12(8.3%) were APF positive. The positive rates of ACPA/AKA/APF antibodies were significantly different among different subtypes(χ²=33.863,26.860,14.395; P<0.01,<0.01,<0.05).The rates in polyarthritis were higher than those in systemic arthritis and oligoarthritis; In 95 children with non-systemic form, the level of TNFα in antibody-positive group (43 cases) was higher than that in antibody-negative group (52 cases) at the early stage(Z=4.785, P<0.01);144 patients were followed up for at least one year,the rates of patients who accepted biologic therapies were significantly different between antibody-positive group and antibody-negative group (50% vs 25%). So do the rates of patients with joint deformities (17.3% vs 2.2%) and with important joints involvement (hip and axis joints) (59.6% vs 14.1%) (χ²=9.249,10.875,32.392; P<0.01,<0.01,<0.01). Further more, the number of joints involved in the antibody-positive group (7.07±3.85) was significantly more than that in the antibody-negative group (2.31±1.64) (F=63.822, P<0.01). Conclusions AKA,APF and ACPA are important in the early typing diagnosis of JIA,and may be closely related to the prognosis of patients with JIA.

Objective: To improve the understanding and diagnosis and treatment level of infant with Takayasu arteritis (TA) by analyzing the clinical features of 14 pediatric patients and reviewing related articles. Methods: The clinical and follow-up data of infants with TA who were admitted to the Children′s Hospital Affiliated to Capital Institute of Pediatrics between July 2016 and May 2019 were retrospectively analyzed.By reviewing related articles, the clinical features of this disease were summarized. Results: The age of 14 patients (including 6 males and 8 females) were between 1 month and 23 days and 28 months.The most common clinical manifestations were fever in 10 cases (71.4%), hypertension in 9 cases (64.3%), weak or no pulse in 5 cases (35.7%). According to the clinical type of lesion vessels, 11 cases (78.5%) were generalized type, 3 cases (21.4%) were brachiocephalic artery type, and there was no thoracic abdominal aorta or single pulmonary artery type in this group.Among 14 infants with TA, 12 cases had common carotid artery, carotid artery, subclavian artery, coronary artery and its branches (anterior descending branch, circumflex branch) involved (85.7%); 11 cases had renal artery involved (78.6%); 9 cases had radial artery involved (64.2%); 8 cases had abdominal aorta involved (57.1%); 6 cases had descending aorta involved (42.9%); 6 cases had thoracic aorta involved (42.9%); 6 cases had superior mesenteric artery involved (42.9%); 5 cases had femoral artery involved (35.7%); 5 cases had pulmonary artery involved (35.7%); and 4 cases had brachial artery involved (28.6%). In those 14 patients, 11 cases were misdiagnosed, and 3 cases had unclear diagnosis, with misdiagnosis duration of 18 days to 2 months.In misdiagnosed cases, 8 cases were misdiagnosed as atypical Kawasaki disease.Among those 14 cases, the ranges of most lesions were gradually decreased, and the slightly involved vessels even completely returned to normal state after treatment in 7 cases.The vascular imaging showed no significant exacerbation or improvement in 4 cases.Nine cases developed hypertension, the blood pressure of whom could be controlled within normal range with hypotensive drugs which could not be interrupted.Physical examination found weak or no pulse in 5 cases who were not improved.Among 14 patients, 7 cases showed normal development, while the height and body mass of another 7 cases were the 25^th percentile below those of normal children of the same age.All 14 patients were followed up for 2-22 months and received regular treatment without recurrence. Conclusions TA patients aged less than 3 years tend to have more blood vessels involved, be in serious condition and have higher rate of misdiagnosis.The disease can be controlled quickly after treatment, but vascular diseases may be developed easily.Some patients have a poor prognosis.
