ABSTRACT
Objective:To compare the efficacy and safety of biologics versus methotrexate in the treatment of severe pediatric plaque psoriasis.Methods:A retrospective matched case-control study was carried out. Twenty children with severe plaque psoriasis from Beijing Children′s Hospital, Capital Medical University from June 2016 to November 2021 were included in this study, and the patients treated with biologics (adalimumab or secukinumab) were matched with those treated with methotrexate at a ratio of 1∶1 according to the psoriasis area and severity index (PASI) score and age. PASI, physician′s global assessment (PGA) , and body surface area (BSA) scores were assessed at weeks 4, 8 and 12 after the start of treatment, and adverse drug reactions were recorded. Statistical analysis was mainly carried out by using Mann-Whitney U test, Fisher′s exact test and generalized estimating equations. Results:At weeks 4 and 8, the proportions of patients achieving PASI75 and PASI90 were significantly higher in the biologics group (PASI75: 7/10, 10/10, PASI90: 5/10, 9/10, respectively) than in the methotrexate group (PASI75: 1/10, 5/10, PASI90: 0, 1/10, respectively; all P < 0.05) , while there was no significant difference between the biologics group and methotrexate group at week 12 (PASI75: 10/10 vs. 8/10, PASI90: 9/10 vs. 4/10, both P > 0.05) . There were no significant differences in the PASI, BSA or PGA scores between the two groups at baseline (all P > 0.05) , while the biologics group showed significantly decreased PASI and BSA scores at weeks 4, 8 and 12, and significantly decreased PGA score at week 8 compared with the methotrexate group (PASI: Z = 2.50, 3.56, 2.63, respectively; BSA: Z = 2.87, 3.57, 2.40, respectively; PGA: Z = 2.81; all P<0.05) . Analysis of changes over time showed that the PASI, PGA and BSA scores in the biologics group significantly decreased at weeks 4, 8 and 12 compared with those at baseline (all P<0.01) ; the PASI and PGA scores significantly decreased at weeks 8 and 12 compared with the corresponding scores at week 4 (all P<0.05) ; however, there were no significant differences in the PASI, PGA or BSA scores between week 12 and 8 (all P>0.05) . In the methotrexate group, the PASI, PGA and BSA scores at weeks 4, 8 and 12 were all significantly lower than the corresponding scores at the previous adjacent time points (all P<0.05) . There was no significant difference in the incidence of adverse reactions between the two groups ( P = 0.650) , and no serious adverse reactions occurred in either group. The main adverse reaction was infection in the biologics group, while infection and elevation of transaminase levels were common in the methotrexate group. Conclusion:Biologics and methotrexate were both effective and safe for the treatment of severe pediatricplaque psoriasis, and biologics facilitated rapider achievement of PASI75 and PASI90 compared with methotrexate.
ABSTRACT
Objective:To assess the effectiveness and characteristics of intratumoral radioactive seed implantation in pancreatic cancer pain management.Methods:Clinical data of 160 patients with pancreatic cancer receiving radioactive seed implantation were retrospectively analyzed. Both pre- and postoperative pain intensities were evaluated using the visual analog scale (VAS) .Results:About 71.88% (115) of 160 patients experienced abdominal or low back pain. Postoperative pain in 104 patients was relieved at various degrees after radioactive seed implantation with an analgesic efficacy of 90.43% (the efficacy for abdominal and low back pain relief was 86.52% and 96.34%, respectively). The between-group difference was statistically significant. Pain relief was observed 1-7 days postoperatively, and the maximal degree of pain relief was achieved 2-14 days after treatment initiation.Conclusion:Intratumoral implantation of radioactive seeds was microinvasive, quick-acting, and effective in pancreatic cancer pain management.
ABSTRACT
Objective: To explore the diagnostic values of HK2 testing and single-cell sequencing in the urothelial carcinoma (UC). Methods: The qualified urine specimens of 265 suspected UC patients or postoperative patients from the Cancer Hospital of Chinese Academy of Medical Sciences, Beijing, China were collected. Both exfoliative cytology and HK2 testing were performed on clinically suspected UC or postoperative patients. The performance of diagnostic cytology and HK2, including consistency, sensitivity, specificity, positive predictive value and negative predictive value, was evaluated based on histopathological, clinical and imaging diagnosis. Isolated HK2 metabolically abnormal cells were subject to single-cell sequencing to verify the reliability of HK2 detection performance and to explore the molecular characteristics of UC. Results: The concordance rate of HK2 testing and cytology for detecting UC was 90.3% (102/113, Kappa=0.604). Compared with cytology, the sensitivity of HK2 was significantly higher (85.2% versus 75.6%, P=0.024). The detection sensitivity of combined HK2 testing and cytology was increased to 91.1%. HK2 testing was significantly more sensitive than cytology for diagnosing UC in the upper urinary tract (81.8% versus 65.5%, P=0.022). It was also more sensitive than cytology for diagnosing early-stage UC (82.6% versus 69.5%, P=0.375) and low-grade UC (69.6% versus 47.8%, P=0.125). Single-cell sequencing of the ten patients, whose samples were positive for HK2, demonstrated highly concordant copy number variations (CNVs) in tumor cells from the same UC patient, with heterogeneity in CNV profiles among different patients. Deletion of chromosome 8p was found in 3 of the 4 urine samples of renal pelvis UC. The 2 patients with benign lesions had no CNVs in all sequenced cells. Conclusions: The test for abnormal urinary glycolytic HK2 metabolism can assist urine cytology to improve the sensitivity of UC diagnosis, and it provides a novel and reliable approach for early detection of upper urinary tract UC and lower grade UC. Meanwhile, this study has preliminarily revealed the feasibility of single-cell sequencing in urinary samples, which is expected to improve the diagnostic specificity of HK2 testing.

Objective:To investigate clinical characteristics of pediatric psoriasis based on the information systems from two children′s hospitals.Methods:Clinical data on outpatients confirmly diagnosed with pediatric psoriasis were collected from information systems of Beijing Children′s Hospital affiliated to Capital Medical University and Children′s Hospital of Chongqing Medical University from January 1, 2015 to December 31, 2019, and a clinical and epidemiological investigation was conducted. Statistical analysis was carried out by using t test and chi-square test. Results:A total of 5 235 children with psoriasis were included, with the ratio of male to female being 1∶1.08. Their age at the clinic visit ( M [ Q1, Q3]) was 8.37 (6.48, 10.50) years, and the school-age children were the most common population; their age at onset was 7.57 (5.37, 9.82) years. Among the 5 235 children with psoriasis, there were 3 195 (60.82%) with psoriasis vulgaris, 281 (5.37%) with pustular psoriasis, 19 (0.36%) with erythrodermic psoriasis, and 1 (0.02%) with psoriatic arthritis. The trunk (87.76%, 1 097/1 250) was most frequently affected, followed by the limbs (87.68%, 1 096/1 250) , the scalp (62.56%, 782/1 250) , and the face and neck (35.76%, 477/1 250) . Among the 5 235 patients, 4 319 (82.50%) received topical treatments, 177 (3.38%) received systemic treatments, and 832 (15.89%) were treated with antibiotics. Among 3 497 children who received initial treatment regimens, the disease could be controlled in 3 423 (97.88%) without change in treatment regimens, while treatment regimens needed to be adjusted in 2.12%. Conclusions:In the two children′s hospitals, most children with psoriasis developed this condition and visited the clinic at school age, and the predominant clinical type was psoriasis vulgaris. Most skin lesions were extensive, and commonly occurred on the trunk and limbs. Scalp involvement was not uncommon. The condition could be controlled by topical treatments in most children with psoriasis, while a few patients needed systemic treatments.
ABSTRACT
Objective:To investigate the method and effect of microneurosurgery in the treatment of recurrent craniopharyngioma.Methods:The clinical data of 41 recurrent craniopharyngioma patients treated by microneurosurgery in Capital Medical University Sanbo Brain Hospitalfrom January 2018 to January 2022 were retrospectively analyzed.Results:Among the 41 patients, 38 cases were treated with the frontal basal interhemispheric approach and 3 cases with the translongitudinal fissure combined with the transSylvian fissure approach. Gross total resection was performed in 34 cases (82.9%) and subtotal resection in 7 cases (17.1%). One patient (2.4%) died of pulmonary embolism during perioperative period. All patients had transient electrolyte disorder after operation, and recovered within 3 months after treatment. All patients had endocrine dysfunction. After 3 months of hormone replacement therapy, 11 patients were cured. Visual acuity decreased in 3 cases after operation, and 2 cases improved after treatment.Conclusions:Surgical treatment of recurrent craniopharyngioma is very difficult, which is a great challenge for doctors and patients. However, through the individualized evaluation of the patients and the meticulous technique of the doctors during the operation, a satisfactory effect can be achieved post the operation of recurrent craniopharyngioma.
ABSTRACT
Objective:To explore the etiology and treatment of craniopharyngioma with aneurysm.Methods:Seven cases of craniopharyngioma with aneurysm from March 2014 to October 2019 treated in Sanbo Brain Hospital, Capital Medical University were retrospectively analyzed. Among the 7 patients, there were 5 males and 2 females. There were 4 cases of recurrent craniopharyngiomas, 1 case of primary tumor and 2 cases of non-recurrence tumor. Three patients with blood blister-like aneurysms were treated with microsurgical suture after craniopharyngioma resection. Among the three cases with internal carotid artery fusiform aneurysm, 1 case underwent craniopharyngioma resection after internal maxillary artery-radial artery-middle cerebral artery bypass and isolation of the aneurysm; 1 case only underwent internal maxillary artery-radial artery-middle cerebral artery bypass and isolation of the aneurysm for non-recurrence tumor; 1 case underwent craniopharyngioma resection and dynamic observation of aneurysm. One case with a cystic aneurysm of the middle cerebral artery was clipped and the craniopharyngioma did not relapse.Results:All patients had no serious postoperative complications. During the follow-up period, there was no recurrence of craniopharyngioma, no recurrence of treated aneurysms, and the stability of aneurysms was observed.Conclusions:Inflammatory stimulation of craniopharyngioma cystic fluid and operation itself are the important reasons for the occurrence of aneurysms after craniopharyngioma surgery. Choosing appropriate surgical methods can complete the removal of craniopharyngioma and the treatment of aneurysms at one time.
ABSTRACT
Objective:To evaluate the effect of oral acitretin on the height and bone development of children.Methods:Clinical and imaging data were collected from 106 children receiving oral acitretin for at least 1 month in Department of Dermatology, Beijing Children′s Hospital from March 2007 to January 2021, and retrospectively analyzed. The main outcome measures were height and near-adult height. Multivariate logistic regression analysis was carried out to investigate relevant factors for short stature in children, and non-inferiority test was used to analyze the proximity of the actual height to target height of children who had reached near-adult height. The secondary outcome measures were bone age and epiphyseal closure. Wilcoxon signed-rank test was used to analyze differences in the value of bone age minus chronological age between the baseline and last follow-up, and the premature closure of epiphysis was also evaluated.Results:Among the 106 children, 62 were males and 44 were females; 84 were diagnosed with pustular psoriasis, 10 with psoriasis vulgaris, 11 with pityriasis rubra pilaris, and 1 with lupus miliaris disseminatus faciei. These children received oral acitretin at doses of <1 mg·kg -1·d -1 for 1 - 90 months. Among the 96 children aged under 18 years, 91 (94.8%) were of normal stature, and 5 (5.2%) were short in stature; among the 83 children receiving acitretin monotherapy, 81 (97.6%) were of normal stature, and 2 (2.4%) of short stature. Binary logistic regression analysis showed that the risk of short stature caused by acitretin combined with glucocorticoid therapy was 76.57 times higher than that of acitretin monotherapy ( OR = 77.57, 95% CI: 2.20 - 2 738.82, P = 0.017) , while the type of disease, gender, age at onset, age at initial treatment with acitretin, course of treatment, and average daily dose of acitretin did not significantly affect the stature of children ( P = 0.988, 0.214, 0.087, 0.078, 0.066, 0.350, respectively) . At the last follow-up visit, 13 children who had reached near-adult height were of normal stature, and the non-inferiority test showed that their near-adult height was not inferior to the target height (Satterthwaite = 0.23, P = 0.030) . Bone age was evaluated in 45 children at baseline and last follow-up visit, there was no significant difference in the value of bone age minus chronological age between the baseline and last follow-up ( Z = -0.85, P = 0.250) , and no patients experienced premature closure of epiphysis before and after the treatment. Conclusion:This study preliminarily revealed that oral acitretin at doses of <1 mg·kg -1·d -1 for less than 90 months might not significantly affect the height and bone development of children.
ABSTRACT
Objective:To explore the impact of occupational ionizing radiation exposure on blood indicators including white blood cell（ WBC）， red blood cell （RBC）， hemoglobin （Hb）， platelet （PLT） were analyzed. Methods:A total of 237 medical radiation workers in Yangpu district， Shanghai were recruited and divided into observation group and control group， according to individual average dose of external exposure. The annual effective dose in observation group was 0.357 7-4.704 3 mSv， and the median dose was 0.536 8 mSv （0.441 2-0.893 8）. The annual effective dose in control group was 0.031 2-0.350 8 mSv， and the median dose was 0.199 2 mSv （0.143 8-0.252 8）. Routine blood tests were conducted twice in the occupational health examinations from 2017 to 2019 and the results were collected. Chi-square test， Mann-Whitney U test， and generalized estimating equations （GEE） model were used for statistical analysis. Results:Compared to the first examination， the risk of having abnormal Hb increased （OR=1.029， 95%CI： 1.006-1.053）. After adjusting the factors of age， gender， seniority and exposure time， the risk of Hb abnormality in the observation group was lower than that in the control group （OR=0.422， 95%CI：0.198-0.898）. There was no significant difference between the observation and control groups in the risk of abnormal WBC， RBC， and PLT. Conclusion:Exposure to occupational ionizing radiation may increase the risk of abnormal Hb， while there is no significant change in WBC， RBC and PLT. Radiation workers should have full protection at work and be under appropriate occupational health management.
ABSTRACT
Objective:To study the clinical features of the "migration birds" population in Hainan Province in winter presenting with acute cholecystitis.Methods:Patients who were diagnosed to suffer from acute cholecystitis in the winter months from November to February of the following year of 2017, 2018 and 2019 and admitted in Hainan Hospital of Chinese PLA General Hospital were included in this study. The "migration birds" patients who arrived in Hainan Province in less than 30 days were defined as the short-term group ( n=49), 30-89 days as the mid-term group ( n=24), more than 90 days as the long-term group ( n=48). The general information, associated medical diseases, clinical presentations, interventional strategies and in-hospital outcomes were compared, and further analyze the clinical characteristics of patients with purulent cholecystitis and non-purulent cholecystitis in the short-term group. Results:Of 120 patients, there were 49 patients in the short-term group (29 males and 20 females with an average age of 65.18±15.02 years), 24 patients in the mid-term group (13 males and 11 females with an average age of 66.21±11.93 years), and 48 patients in the long-term group (30 males and 18 females with an average of 60.73±12.54 years). The general information, interventional strategies and in-hospital outcomes were similar among the three groups. When compared with patients in the long-term group, patients in the short-term group had higher incidences of hypertension [20.83% (10/48) vs 48.98% (24/49)] and diabetes [10.42% (5/48) vs 30.61% (15/49)]. The gallbladder wall in the short-term group was significantly thicker than that in the long-term group [0.60(0.40, 0.70) cm vs 0.50(0.30, 0.60) cm, P<0.017]. The proportion of purulent cholecystitis in the short-term group was significantly higher than that in the long-term group [48.15% (13/27) vs 17.24% (5/29) , P<0.017] . In the short-term group, the incidences of silt-like stones of purulent cholecystitis [38.46% (5/13) vs 14.29% (2/14)], gallbladder perforation [30.77% (4/13) vs 0], gallbladder gangrene [53.85% (7/13) vs 7.14% (1/14)], perigallbladder effusion [76.92% (10/13) vs 14.29% (2/14)], abdominal effusion [46.15% (6/13) vs 7.14% (1/14)] were significantly higher than that of patients with non-purulent cholecystitis, (all P<0.05). Conclusion:Patients presenting with acute cholecystitis after arrival in Hainan in the short term had more severe inflammation with complications of suppuration, perforation and gangrene. Patients with hypertension and diabetes were the high risk group of patients presenting with acute cholecystitis after short-term arrival in Hainan.
ABSTRACT
Objective:To investigate the clinical and neuroimaging features of atypical teratoid/rhabdoid tumors (AT/RT) of the central nervous system and the survival prognosis in different locations.Methods:The clinical data of 27 patients with AT/RT confirmed by biopsy or postoperative pathology in Sanbo Brain Hospital of Capital Medical University from October 2012 to September 2020 were collected, including 17 males and 10 females, aged (7.6±10.0) years, ranging from 0.2 to 39.0 years old.The clinical features and the results of the first preoperative imaging examination were retrospectively analyzed.The patients were divided into supratentorial, infratentorial and trans supratentorial and infratentorial groups according to the location.The survival time of the three groups was compared by Kaplan-Meier survival curve.Results:All patients presented with headache, including 12 cases with vomiting.There were 12 cases of supratentorial, 10 cases of infratentorial and 5 cases of supratentorial and infratentorial.There were 20 cases of cystic degeneration, 7 cases of calcification, 6 cases of hemorrhage and 13 cases of peritumoral edema.The median survival time of patients with infratentorial AT/RT was longer than that of patients with supratentorial and transtentorial AT/RT (χ 2=7.353, P=0.025). Conclusion:Central nervous system AT/RT is easy to occur in young children, and the survival time of AT/RT patients is longer.
ABSTRACT
Objective: To observe the incidence and treatment of radiation rectal injury complicated with anxiety, depression and somatic symptom disorder. Methods: A cross-sectional survey research method was carried out. Patients with radiation rectal injury managed by members of the editorial board of Chinese Journal of Gastrointestinal Surgery were the subjects of investigation. The inclusion criteria of the survey subjects: (1) patients suffered from pelvic tumors and received pelvic radiotherapy; (2) colonoscopy showed inflammatory reaction or ulcer in the rectum. Exclusion criteria: (1) patient had a history of psycho-somatic disease before radiotherapy; (2) patient was unable to use a smart phone, unable to read and understand the questions in the questionnaire displayed on the phone; (3) patient refused to sign an informed consent form. According to the SOMA self-rating scale, PHQ-15 self-rating scale, GAD-7 and PHQ-9 self-rating scale, the electronic questionnaire of "Psychological Survey of Radiation Proctitis" was designed. The questionnaire was sent to patients with radiation rectal injury managed by the committee through the WeChat group. Observational indicators: (1) radiation rectal injury symptom assessment: using SOMA self-rating scale, radiation rectal injury symptom classification: mild group (≤3 points), moderate group (4-6 points) and severe group (> 6 points); (2) incidence of anxiety, depression and physical disorder: using GAD-7, PHQ-9 and PHQ-15 self-rating scales respectively for assessment; (3) correlation of radiation rectal injury symptom grading with anxiety, depression, and somatic symptom disorder. Results: Seventy-one qualified questionnaires were collected, of which 41 (56.9%) were from Guangzhou. Among the 71 patients, 6 were males and 65 were females; the mean age was (55.7±9.3) years old and 48 patients (67.6%) were less than 60 years old; the median confirmed duration of radiation rectal injury was 2.0 (1.0, 5.0) years. (1) Evaluation of symptoms of radiation rectal injury: 18 cases of mild (25.4%), 27 cases of moderate (38.0%), and 26 cases of severe (36.6%). (2) Incidence of anxiety, depression and somatic disorder: 12 patients (16.9%) without comorbidities; 59 patients (83.1%) with anxiety, depression, or somatic disorder, of whom 2 patients only had anxiety, 1 patient only had depression, 9 only had somatic disorder, 2 had anxiety plus depression, 4 had anxiety plus somatic disorder, 2 had depression plus somatic disorder, and 40 had all three symptoms. (3) correlation of radiation rectal injury grading with anxiety, depression, and somatic symptom disorder: as compared to patients in mild group and moderate group, those in severe group had higher severity of anxiety and somatic symptom disorder (Z=-2.143, P=0.032; Z=-2.045, P=0.041), while there was no statistically significant difference of depression between mild group and moderate group (Z=-1.176, P=0.240). Pearson correlation analysis revealed that radiation rectal injury symptom score was positively correlated with anxiety (r=0.300, P=0.013), depression (r=0.287, P=0.015) and somatic symptom disorder (r=0.344, P=0.003). Conclusions: The incidence of anxiety, depression, and somatic symptom disorder in patients with radiation rectal injury is extremely high. It is necessary to strengthen the diagnosis and treatment of somatic symptom disorder, so as to alleviate the symptoms of patients with pelvic perineum pain and improve the quality of life.

Objective To analyze the endemic situation of schistosomiasis in Jiangshan City from 2008 to 2018, so as to provide evidence for formulating the future control strategy. Methods The data regarding Oncomelania snail survey and control, schistosomiasis examinations and environmental improvements were collected in Jiangshan City from 2008 to 2018. The changes in snail status and morbidity due to Schistosoma japonicum infections were analyzed to assess the effectiveness of comprehensive schistosomiasis control. Results From 2008 to 2018, a total of 61 220 person-times were examined for S. japonicum infections in Jiangshan City, and the overall seroprevalence of S. japonicum infections was 0.56% (343/61 220); however, no egg-positives were detected. Among 4 231 cattle screened for S. japonicum infections using blood tests in Jiangshan City during the period from 2008 to 2018, 12 were sero-positive, with sero-prevalence of 0.28% (12/4 231), and no egg-positives were identified. There were 422 snail habitats identified in Jiangshan City during the study period, covering an area of 46.915 hm2, and among the 31 686 snails dissected, no S. japonicum infections were detected. An area of 3 625.492 hm2 snail habitats were subjected to repeated snail control and 11 settings were given environmental improvements, covering snail habitats of 17.880 hm2 and historical snail habitats of 204.380 hm2. Conclusions Following the implementation of environmental improvements-based comprehensive schistosomiasis control, the endemic situation of schistosomiasis is stable in Jiangshan City; however, there is still a risk of snail importation and re-emerging schistosomiasis. Therefore, the monitoring of snails and morbidity due to S. japonicum infections should be intensified in the city.
ABSTRACT
Objective To investigate clinical manifestations,pathological features and outcomes of primary osteoma cutis in children.Methods Eleven children with confirmed primary osteoma cutis diagnosed in Department of Dermatology,Beijing Children's Hospital between 2011 and 2018 were included into this study.The clinical manifestations,histopathological features,and outcomes were analyzed retrospectively.Results Among the 11 patients,7 were males and 4 were females.Primary osteoma cutis occurred within 22 months after birth in all the children,the median age of onset was 1 month,and the disease occurred during the first 6 months of life in 10 children.The skin lesions were characterized by skincolored or reddish indurated papules,plaques or nodules of varying size with slight epidermal atrophy.Three patients had local skin lesions,and 8 had multiple skin lesions.Serum calcium and parathyroid hormone levels were within normal limits in all the children,and no developmental deformity was observed at birth in any of the children.Histopathological examination revealed the formation of mature lamellar bone in the dermis in all the cases,which involved the subcutaneous adipose tissue in 5 cases.The skin lesions became stable 8-18 months after the occurrence in 10 patients,which was consistent with primary plaquelike osteoma cutis.Only 1 patient underwent a slowly progressive course,and the skin lesions involved subcutaneous deep tissues,leading to dyskinesia,which was consistent with progressive osseous heteroplasia.Conclusions Primary osteoma cutis in children mostly occurs in infancy,whose clinical manifestations are atrophic,indurated plaques or nodules,and its main pathological feature is the formation of mature lamellar bone.Long-term follow-up is needed,and attention should be paid to the occurrence of progressive osseous heteroplasia.
ABSTRACT
Objective To compare the efficacy and safety of the long-term intermittent maintenance treatment with tacrolimus 0.03％ ointment versus traditional treatment in reducing relapses and prolonging the recurrence interval in children with moderate to severe atopic dermatitis (AD).Methods A two-phase randomized,open-labelled,controlled clinical trial was conducted from September 2012 to November 2013.In the first phase,a total of 171 children aged 2-15 years with moderate to severe AD were enrolled from 7 hospitals in China,and received conventional treatment with tacrolimus 0.03％ ointment twice a day for 2-6 weeks.At the end of the treatment,the patients who achieved an investigator's global assessment (IGA) score ≤ 2 (n =125) were randomly classified into 2 groups to receive the second-phase treatment:test group (n =62) receiving intermittent maintenance treatment with tacrolimus 0.03％ ointment twice a week (Monday and Thursday),and control group (n =63) receiving no treatment.If the patients in the 2 groups experienced relapse,they received conventional treatment with tacrolimus 0.03％ ointment twice a day.The overall observation period was 6 months.The primary endpoint was the time to the first relapse,which was defined as the number of days from the end of the first-phase treatment to the first relapse.The secondary endpoints included the number of relapses at the second-phase trial,the disease severity at the time of relapse,the duration of relapse,the pruritus score at the time of relapse,the total amount of tacrolimus ointment used,the total response rate at the second-phase trial,and the incidence of adverse events.Results A total of 125 children with AD were enrolled into the second-phase trial,and 121 of them completed the follow-up.Among the 121 patients,the recurrence rate was significantly lower in the test group (25/60,41.7％) than in the control group (46/61,75.4％;x2 =14.20,P ＜ 0.001).The time to the first relapse was significantly longer in the test group (46.9 ± 37.7 d) than in the control group (28.8 ± 32.3 d;Z =1 093.50,P =0.020).The total number of recurrence was 31 and 86 in the test group and control group respectively,and the mean number of recurrence in each patient was significantly lower in the test group (0.52 ± 0.68) than in the control group (1.41 ± 1.23,t =4.96,P ＜ 0.001).There were no significant differences between the two groups regarding disease severity during relapse (eczema area and severity index:Z =971.50,P =0.39),duration of relapse (Z =747.00,P =0.07),and pruritus score during relapse (Z =894.00,P =0.95).The therapeutic drug was tolerated well in all the children,and no tacrolimus-related serious adverse events occurred.Conclusion The intermittent maintenance treatment with tacrolimus 0.03％ ointment twice a week for 6 months can effectively and safely prevent and reduce relapses,and prolong the recurrence interval in children with moderate to severe AD.

ABSTRACT
It was widely known that retinoic acid inducible gene I (RIG-I) functions as a cytosolic pattern recognition receptor that initiates innate antiviral immunity by detecting exogenous viral RNAs. However, recent studies showed that RIG-I participates in other various cellular activities by sensing endogenous RNAs under different circumstances. For example, RIG-I facilitates the therapy resistance and expansion of breast cancer cells and promotes T cell-independent B cell activation through interferon signaling activation by recognizing non-coding RNAs and endogenous retroviruses in certain situations. While in hepatocellular carcinoma and acute myeloid leukemia, RIG-I acts as a tumor suppressor through either augmenting STAT1 activation by competitively binding STAT1 against its negative regulator SHP1 or inhibiting AKT-mTOR signaling pathway by directly interacting with Src respectively. These new findings suggest that RIG-I plays more diverse roles in various cellular life activities, such as cell proliferation and differentiation, than previously known. Taken together, the function of RIG-I exceeds far beyond that of a pattern recognition receptor.

Objective To investigate the efficacy of intravitreal injection of monoclonal antibody in the treatment of patients with exudative age-related macular degeneration (AMD).Methods Together 33 patients (33 eyes) with exudative AMD from February 2010 to May 2015 selected in this study were treated with intravitreal injection of ranibizumab,followed by examination of the best corrected visual acuity before and after surgery by international standard logarithmic visual acuity chart.The differences in ophthalmic artery (OA),central retinal artery (CRA) and ciliary artery hemodynamic parameters before and after operation were compared,and fundus fluorescein angiography (FFA) was used to measure and calculate the changes in choroidal neovascularization (CNV) fluorescein leakage area before and after operation.Results The best corrected visual acuity was significantly improved 1 week after operation when compared with preoperative data [(0.29 ± 0.18) vs.(0.16 ± 0.15)],with significant difference (P =0.002).And 7 days after operation,the area of CNV fluorescein leakage was less than that of postoperative data [(8.48 ± 6.13)mm2 vs.(11.39 ± 6.12)mm2],and the difference was statistically significant (P =0.029).However,there was no difference in OA,CRA,the peak systolic velocity (PSV),end diastolic blood flow velocity (EDV)and resistance index (RI),pulsatility index (PI) in the treatment eyes between before operation and 1,4 weeks after operation (all P ＞ 0.05).Conelusion Intravitreal injection of ranibizumab in the treatment of exudative AMD is safe and effective and can effectively improve the visual acuity and alleviate CNV leakage,without adveme effects on patients' hemodynamics.
ABSTRACT
BACKGROUND: The occurrence and development of osteoporosis are shown to be directly related to the inflammatory response induced by immune dysfunction. OBJECTIVE: To summarize the mechanisms of osteoclast differentiation and formation at cellular and molecular levels, as well as the underlying mechanisms of several kinds of medical herbs against osteoporosis, thus paving ways for finding more effective and safe herbs for anti-osteoporosis.METHODS: PubMed database was retrieved using the English keywords of (osteoporosis OR bone loss) AND lipopolysaccharide AND bone resorption", and WanFang database was searched with the Chinese keywords of "osteoarthritis, receptor activator of nuclear factor-κB ligand, lipopolysaccharide,Dendrobium moniliforme,Portulaca oleracea,Ampelopsis sinica,Schizonepeta".The literatures addressing osteoporosis, inflammation and herbal medicine were screened, and those using lipopolysaccharide-induced mouse models were included. Finally, four eligible literatures were enrolled for review. RESULTS AND CONCLUSION:In vivo experiments,CT images and pathological sections of the cancellous bone in the mouse distal femur show that Dendrobium moniliforme,Purslane oleracea,Ampelopsis sinica,and Schizonepeta exert inhibitory effects on lipopolysaccharide-induced osteoporosis.In vitro experiments reveal that these four kinds of herbs fight against osteoporosis by inhibiting osteoclast differentiation and further reducing bone resorption.
ABSTRACT
Objective To explore effective therapy for Kasabach-Merritt syndrome (KMS).Methods Clinical data were collected from 11 infants with KMS in the Department of Dermatology,Beijing Children's Hospital affiliated to Capital Medical University between 2015 and 2017,and the efficacy of vincristine combined with glucocorticoids for the treatment of KMS was evaluated.Results Of the 11 patients,4 were male and 7 were female.Their average age at the first clinic visit was 87.91 ± 72.01 days (range,1-212 days).Most of the hemangiomas manifested as hard violaceous plaques,and skin purpura occurred around the hemangiomas in 5 patients.The initial blood platelet counts of the 11 patients ranged from 4 × 109/L to 32 × 109/L.All the patients were treated with oral prednisone at doses of (2-5) mg· kg 1· d1 combined with intravenous injection of vincristine at a dose of 0.05 mg/kg every week.Among 10 patients treated with glucocorticoids and vincristine,the blood platelet counts became normal after (1.8± 1.23) weeks of treatment,the fibrinogen levels returned to normal after (3.6 ± 1.26) weeks of treatment,and the hemangiomas started to become softer and smaller after (3.9 ± 0.74) weeks.The blood platelet count still did not return to normal in 1 patient after 5 weeks of vincristine treatment.After the treatment with venous embolization,the blood platelet count gradually became normal and remained stable.Conclusion Vincristine combined with glucocorticoids can control the development of hemangioma in infants with KMS,and improve the recovery of blood platelet count.
ABSTRACT
Objective To compare the long-term outcomes between the stenting and the medical therapy in patients with symptomatic intracranial artery stenosis.Methods The articles that compared between the stenting and the medical therapy in patients with symptomatic intracranial artery stenosis searched from PubMed,Cochrane Lirary,EMBASE,and Google Scholar.A meta-analysis was conducted to evaluate risks of stroke recurrence and composite vascular events at 1 years,and composite vascular events risk and clinical outcomes (a good outcome was defined as the modified Rankin scale score 0-2) at 2 years after stent therapy or medical therapy.Results Six studies,comprising a total of 920 patients with symptomatic intracranial artery stenosis were included,458 in the stenting group,and 462 in the medical therapy group,their mean age was 61.8 years and 66％ were males.The meta-analysis showed that there were no significant differences in the risks of stroke recurrence (pooled odds ratio [OR] 1.74,95％ confidence interval [CI]0.95-3.20;P =0.07) and composite vascular events (pooled OR 1.27,95％ CI 0.74-2.16;P =0.39) at 1 year,as well as composite vascular events risk (pooled OR 1.30,95％ CI 0.89-1.89;P =0.17) and clinical outcome (pooled OR 1.37,95％ CI 0.32-5.82;P =0.67) at 2 years between stenting group and medical therapy group.Conclusions There were no significant differences in the risks of stroke recurrence and composite vascular events at 1 year,as well as composite vascular events risk and clinical outcome at 2 years after stenting or medical therapy in patients with symptomatic intracranial artery stenosis.
