ABSTRACT

OBJECTIVES@#To study the role of plasma exchange combined with continuous blood purification in the treatment of refractory Kawasaki disease shock syndrome (KDSS).@*METHODS@#A total of 35 children with KDSS who were hospitalized in the Department of Pediatric Intensive Care Unit, Hunan Children's Hospital, from January 2019 to August 2022 were included as subjects. According to whether plasma exchange combined with continuous veno-venous hemofiltration dialysis was performed, they were divided into a purification group with 12 patients and a conventional group with 23 patients. The two groups were compared in terms of clinical data, laboratory markers, and prognosis.@*RESULTS@#Compared with the conventional group, the purification group had significantly shorter time to recovery from shock and length of hospital stay in the pediatric intensive care unit, as well as a significantly lower number of organs involved during the course of the disease (P<0.05). After treatment, the purification group had significant reductions in the levels of interleukin-6, tumor necrosis factor-α, heparin-binding protein, and brain natriuretic peptide (P<0.05), while the conventional group had significant increases in these indices after treatment (P<0.05). After treatment, the children in the purification group tended to have reductions in stroke volume variation, thoracic fluid content, and systemic vascular resistance and an increase in cardiac output over the time of treatment.@*CONCLUSIONS@#Plasma exchange combined with continuous veno-venous hemofiltration dialysis for the treatment of KDSS can alleviate inflammation, maintain fluid balance inside and outside blood vessels, and shorten the course of disease, the duration of shock and the length of hospital stay in the pediatric intensive care unit.

ABSTRACT

OBJECTIVES@#To study the application value of metagenomic next-generation sequencing (mNGS) for pathogen detection in childhood agranulocytosis with fever.@*METHODS@#A retrospective analysis was performed on the mNGS results of pathogen detection of 116 children with agranulocytosis with fever who were treated from January 2020 to December 2021. Among these children, 38 children with negative mNGS results were enrolled as the negative group, and 78 children with positive results were divided into a bacteria group (n=22), a fungal group (n=23), and a viral group (n=31). Clinical data were compared between groups.@*RESULTS@#For the 116 children with agranulocytosis and fever, the median age was 8 years at diagnosis, the median turnaround time of mNGS results was 2 days, and the positive rate of mNGS testing was 67.2% (78/116). Compared with the negative group, the bacterial group had a higher procalcitonin level (P<0.05), the fungal group had higher level of C-reactive protein and positive rate of (1,3)-β-D glucan test/galactomannan test (P<0.05), and the fungal group had a longer duration of fever (P<0.05). Among the 22 positive microbial culture specimens, 9 (41%) were consistent with the mNGS results. Among the 17 positive blood culture specimens, 8 (47%) were consistent with the mNGS results. Treatment was adjusted for 28 children (36%) with the mNGS results, among whom 26 were cured and discharged.@*CONCLUSIONS@#The mNGS technique has a shorter turnaround time and a higher sensitivity for pathogen detection and can provide evidence for the pathogenic diagnosis of children with agranulocytosis and fever.

ABSTRACT

OBJECTIVE@#To study the clinical features of vasovagal syncope (VVS) and postural orthostatic tachycardia syndrome (POTS) in children with neurological symptoms at disease onset.@*METHODS@#A retrospective analysis was performed on the medical data of 88 children with the initial symptoms of the nervous system, such as transient loss of consciousness, dizziness, headache, and convulsion, who were finally diagnosed with VVS or POTS.@*RESULTS@#Of the 88 children, there were 35 boys (40%) and 53 girls (60%), with an age of 4-15 years. The peak age of onset was between 10 and 13 years. All the children had the initial symptoms of transient loss of consciousness, dizziness, headache, and convulsion. Nervous system diseases were excluded by electroencephalography, cerebrospinal fluid examination, and cranial MRI. Of the 88 children, 53 (60%) were confirmed with VVS, and 35 (40%) with POTS, according to the results of head-up tilt test (HUTT). Five children with the initial symptom of transient loss of consciousness were misdiagnosed with epilepsy. Predisposing factors were determined for 59 children (67%), and prolonged standing was the most common factor, followed by change in body position and strenuous exercise. Premonitory symptoms were observed in 66 children (75%), among which chest discomfort was the most common symptom, followed by gastrointestinal symptoms (nausea, vomiting, and abdominal pain) and pale complexion. All 88 children received health education and exercise for autonomic nerve function, among whom 53 children with VVS were given oral rehydration salts and 35 children with POTS were given oral rehydration salts and metoprolol. All 88 children were followed up for 18 months, and the response rates to the above treatment at 3, 6, 12, and 18 months of follow-up were 87%, 93%, 93%, and 90% respectively.@*CONCLUSIONS@#In addition to nervous system diseases, functional cardiovascular diseases including VVS and POTS should be considered for children with the initial symptoms of transient loss of consciousness, dizziness, headache, and convulsion. HUTT can be used to make a confirmed diagnosis, and the early treatment can achieve a good outcome.

ABSTRACT

OBJECTIVE@#To detect the expression of cartilage oligomeric matrix protein (COMP) in the synovial chondromatosis of the temporomandibular joint (TMJSC), and to discuss the possible interactions between COMP, transforming growth factor (TGF)-β3, TGF-β1 and bone morphogenetic protein-2 (BMP-2) in the development of this neoplastic disease.@*METHODS@#Patients in Peking University School and Hospital of Stomatology from January 2011 to February 2020 were selected, who had complete medical records, TMJSC was verified histologically after operation. The expressions of COMP, TGF-β3, TGF-β1 and BMP-2 in the TMJSC of the temporomandibular joint were detected by immunohistochemistry and quantitative real-time PCR (RT-PCR) at the protein level and mRNA level respectively, compared with the normal synovial tissue of temporomandibular joint. The histological morphology, protein expression and distribution of TMJSC tissues were observed microscopically, and the positive staining proteins were counted and scored. SPSS 22.0 statistical software was used to analyze the expression differences between the related proteins in TMJSC tissue and the normal synovial tissue of temporomandibular joint and to compare their differences. P < 0.05 indicated that the difference was statistically significant.@*RESULTS@#Immunohistochemical results showed that the positive expression of COMP in TMJSC tissues was mostly found in synovial tissues and chondrocytes adjacent to synovial tissues, and the difference was statistically significant, compared with the normal temporomandibular joint synovial tissues. The positive expression of COMP was significantly different between recurrent TMJSC and non-recurrent ones. The positive expressions of TGF-β3, TGF-β1 and BMP-2 were higher than the normal synovial tissue, and were also mostly found in the synovial cells and adjacent chondrocytes, which was further confirmed by Western blot. According to the RT-PCR results, the expressions of COMP, TGF-β3, TGF-β1 and BMP-2 in TMJSC were higher than those in the normal synovial tissue.@*CONCLUSION@#The expression of COMP in TMJSC of temporomandibular joint increased significantly, compared with the normal synovial tissue. There may be interactions between COMP and cytokines related to the proliferation and differentiation, like TGF-β3, TGF-β1 and BMP-2, which may play a potential role in the pathogenesis of TMJSC.

ABSTRACT

Objective:To observe the effect of warm-unblocking acupuncture plus fluticasone propionate nasal spray on the pulmonary ventilation, level of interferon-γ (IFN-γ) and sleep quality in patients with allergic rhinitis (AR). Methods: A total of 112 AR patients were enrolled between January 2013 and August 2018 and were divided into an observation group and a control group by the random number table method, with 56 cases in each group. Patients in the observation group received warm-unblocking acupuncture plus fluticasone propionate nasal spray, and patients in the control group only received fluticasone propionate nasal spray. The nasal symptom score, pulmonary function indexes, the levels of IFN-γ and interleukin (IL)-4 in serum, and sleep quality in the two groups were compared. Results: After treatment, the total effective rate in the observation group was higher than that in the control group (P<0.05). The nasal symptom score dropped in both groups after treatment (both P<0.05), and the score in the observation group was lower than that in the control group (P<0.05). The pulmonary ventilation indexes all increased significantly after treatment in the observation group (all P<0.05); the forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) ratio (FEV1/FVC) and the forced expiratory flow at 50%, 75% and 25%-75% of the vital capacity (FEF50%, FEF75%, FEF25%-75%) increased after treatment in the control group (all P<0.05); the pulmonary ventilation indexes were higher in the observation group than those in the control group (all P<0.05). The level of IFN-γ increased significantly after treatment in the two groups (both P<0.05) and the level of IL-4 dropped significantly (both P<0.05); the observation group had a higher IFN-γ level (P<0.05) and a lower IL-4 level (P<0.05) compared with the control group. Regarding the Pittsburgh sleep quality index (PSQI), the scores of subjective sleep quality, habitual sleep efficiency and sleep disturbances and the general PSQI score decreased significantly after treatment in both groups (all P<0.05), and the scores in the observation group were significantly lower than those in the control group (all P<0.05). Conclusion: Warm-unblocking acupuncture plus fluticasone propionate nasal spray can effectively control the clinical symptoms and improve pulmonary function in the treatment of AR; this approach can regulate the levels of IFN-γ and IL-4 towards the normal range in AR patients; it can also improve patient’s sleep quality. This method can produce more significant efficacy than fluticasone propionate nasal spray used alone.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the impact of continuous blood purification (CBP) on T-cell subsets and prognosis in children with severe sepsis.</p><p><b>METHODS</b>A total of 42 children with severe sepsis were randomly divided into a control group (n=22) and a CBP group (n=20). The patients in the control group received conventional treatment, while those in the CBP group underwent continuous veno-venous hemofiltration daily 12-24 hours for 3 days besides conventional treatment. Changes in clinical variables and in peripheral blood regulatory T cell subsets were assessed 3 and 7 days after treatment.</p><p><b>RESULTS</b>The pediatric intensive care unit length of stay and duration of mechanical ventilation were significantly shortened and the 28-day mortality rate was significantly lower in the CPB treatment group as compared with the control group (P<0.05). In the CBP treatment group, the percentage of CD3(+), CD4(+), CD8(+) T cell populations and PCIS scores were significantly higher at 3 and 7 days after treatment than before treatment (P<0.05). At 7 days after treatment, the percentage of CD3(+), CD4(+), CD8(+) T cell populations, CD4(+)/CD8(+) ratio and PCIS scores were significantly higher in the CBP group than in the control group (P<0.05).</p><p><b>CONCLUSIONS</b>The CBP treatment may counteract the suppression of immune function and thus improve prognosis in children with severe sepsis.</p>

ABSTRACT

To obtain protective human monoclonal antibody from HIV-1 infected person, we adapted a technology for isolating antigen specific monoclonal antibody from human memory B cells through in vitro B cell activation coupled with RT-PCT and expression cloning. Human B cells were purified by negative sorting from PBMCs of HIV-1 infected individuals and memory B cells were further enriched using anti-CD27 microbeads. Two hundred memory B cells per well were cultured in 96-well round-bottom plates Env-specific antibodies in supernatants were with feeder cells in medium containing EBV and CpG. screened by ELISA after 1-2 weeks' culture. Cells from positive wells of Env-specific antibody were harvested and total RNA was isolated. Human VH and Vkappa or Vlambda genes were amplified by RT-PCR and cloned into IgG1 and kappa or lambda expressing vectors. Functional VH and Vkappa or Vlambda were identified by cotransfecting 293T cells with individual heavy chain and light chain clones followed by analysis of culture supernatants by ELISA for Env-specific antibodies. Finally, corresponding mAb was produced by transient transfection of 293T cells with the identified VH and Vkappa/lambda pair and purified by protein A affinity chromatography. Purified monocolonal antibodies were used for HIV-1 specific antibody-dependent cell-mediated cytotoxicity (ADCC) and neutralizing activity assay. Four monocolonal Env-specific antibodies were isolated from one HIV-1 subtype B' infected individual. Two of them showed strong ADCC activity and one showed weak neutralizing activity against HIV-1. Its further studies on their application in therapeutic or prophylactic vaccines against HIV-1 should be grounded.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the histological features of oral leukoplakia which underwent malignant transformation and its correlation with the clinical manifestation.</p><p><b>METHODS</b>A total of 1832 cases of oral leukoplakia were reviewed and the clinicopathological characteristics of malignant transformation were analyzed.</p><p><b>RESULTS</b>Malignant transformation occurred in 85 cases (4.6%) of the 1832 cases. Thirty cases (2.1%) of 1404 cases with simple epithelial hyperplasia had malignant transformation. Fifty-five cases (12.9%) in 428 cases with epithelial dysplasia were transformed to malignancy, especially in the cases with moderate or severe dysplasia, in which the ratio of malignant transformation was higher than in the cases with simple epithelial hyperplasia (P < 0.005). Clinical parameters associated with an increased risk of malignant transformation were female gender and epithelial dysplasia was more often seen in non-homogenous leukoplakias than in homogenous (P < 0.005).</p><p><b>CONCLUSIONS</b>Non-dysplastic leukoplakia may become malignant. Epithelial dysplasia was associated with an increased risk of malignant transformation. Leukoplakia in female may be at a higher risk for malignant transformation.</p>

ABSTRACT

<p><b>OBJECTIVE</b>to study the characteristics of arrhythmia after a positive head-up tilt table test (HUTT).</p><p><b>METHODS</b>head-up tilt table test (BHUT) or sublingual nitroglycerin-provocation head-up tilt table test (SNHUT) were performed in 1374 patients at the Second Xiangya Hospital of Central South University from March of 2001 to August of 2009. Arrhythmias were recorded in 169 patients after a positive HUTT [57 male, age 6 - 65 years, 86 children < 18 years, mean age (23.1 ± 14.8) years].</p><p><b>RESULTS</b>arrhythmias developed in 75 patients (44.38%) post a positive BHUT and in 94 patients (55.62%) post a positive SNHUT. Major types of arrhythmias were sinus bradycardia (143/169, 84.62%), junctional escape rhythm (55/169, 32.54%) and sinus arrest (26/169, 15.38%). Sinus bradycardia was more common in adult (P < 0.01). Occurrence of junctional escape rhythm and sinus arrest was not affected by age, gender and test mode. Arrhythmia and the manifestation of syncope or pre-syncope occurred simultaneously in 77 (45.56%) patients and mainly in BHUT, while arrhythmia appeared later than the syncope manifestation in 92 (54.44%) patients and mainly in SNHUT (P < 0.05). Arrhythmia and blood pressure reduction occurred simultaneously in 84 (53.50%) cases and mainly in BHUT, while arrhythmia appeared later than reduction of blood pressure in 73 (46.50%) cases and mainly in SNHUT (P < 0.01).</p><p><b>CONCLUSIONS</b>(1) the common types of arrhythmia were sinus bradycardia, junctional escape rhythm and sinus arrest after a positive HUTT. Occurrence of sinus arrest was not affected by age, gender and test mode. (2) In BHUT, arrhythmia occurred mostly simultaneously with the manifestation of syncope or pre-syncope and blood pressure reduction, while arrhythmia appeared later in SNHUT.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the changes in clinical features of vasovagal syncope (VVS) in children.</p><p><b>METHODS</b>From January 2000 to September 2009, 841 children with unexplained syncope or prodromata were enrolled. They were assigned to two groups according to the period of visiting hospital: group A (from January 2000 to December 2004, n=129) and group B (from January 2005 to September 2009, n=712). They were assigned to three age groups: 4-6 years old, 7-10 years old and 11-18 years old. A head-up tilt table test (HUTT) was performed on all the subjects.</p><p><b>RESULTS</b>The total positive rate of HUTT was 45.3% (381/841). Compared with that in group A, the positive rate of HUTT in group B increased significantly (47.5% vs 33.3%; P<0.05). The positive rate of HUTT in female children was significantly higher than that in male children (49.3% vs 37.9%; P<0.05). The positive rate of HUTT increased with age and it was the highest in children at age of 11-18 years (49.2%), followed by in children at age of 7-10 years (44.1%) and 4-6 years (37.1%) (P<0.05). The children at age of 7-10 years and 11-18 years from group B showed significantly higher positive rate of HUTT than those from group A (46.2% vs 27.8%; 54.0% vs 32.6%, P<0.05). Vasodepressor type was the most common response type (70.9%) shown by HUTT compared with mixed type (25.5%) and cardioinhibitory type (3.6%) (P<0.05). The proportion of children with vasodepressor response type in group B was significantly higher than that in group A (72.5% vs 58.1%; P<0.05).</p><p><b>CONCLUSIONS</b>There were obvious changes in the prevalence of VVS and response types before and after five years, suggesting that the development of VVS may be attributed to many factors, such as social factors, mental factor and life style.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the risk factors of postoperative renal failure (RF) in the patients with type A dissection of aorta operated on with cerebral perfusion and deep hypothermia circulatory arrest (DHCA).</p><p><b>METHODS</b>From January 2004 to October 2007, 157 patients with type A dissection of aorta underwent surgical procedures with cerebral perfusion and DHCA. There were 115 male patients and 42 female patients with the age from 17 to 76 years old. Antegrade selective cerebral perfusion through axillary artery was performed for 129 patients and retrograde cerebral perfusion from superior cava vein was performed for 28 patients. All the factors underwent univariate and multivariate analysis.</p><p><b>RESULTS</b>Mean cardiopulmonary bypass duration was (188.0 +/- 10.8) min and mean cerebral perfusion time was (36.0 +/- 3.1) min. Fifteen patients died in hospital and the hospital mortality was 9.6%. Permanent neurological dysfunction (PND) occurred in 8 patients (5.1%). Postoperative RF was observed in 20 patients (12.8%). Multivariate analysis showed the preoperative renal dysfunction (P = 0.042, OR = 4.41) and over seventy-year-old patients (P = 0.049, OR = 4.94) were found to be the risk factors of postoperative RF. There was a higher incidence of death (45%, P = 0.001) and PND (25%, P = 0.009) in the patients of postoperative RF when compared with the other patients.</p><p><b>CONCLUSION</b>The preoperative renal dysfunction and elderly patients were found to be the risk factors of postoperative RF after type A dissection of aorta surgery.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinicopathological features and behavior of a group of jaw cysts with a solely orthokeratinized lining epithelium.</p><p><b>METHODS</b>20 cases of this cyst type were reported under the term of orthokeratinized odontogenic cyst (OOC) and their clinical, histological and immunocytochemical features were compared with that of odontogenic keratocyst (OKC).</p><p><b>RESULTS</b>The cysts of the present series were all solitary lesions, occurred mostly in young male patients, and showed a predilection for the posterior mandible areas. Follow-up of 15 patients revealed no recurrence following enucleation. Histological and immunocytochemical studies indicated that OOC epithelium lacked the typical features of OKC and appeared to show a lower proliferative activity.</p><p><b>CONCLUSION</b>These findings suggest that OOC is clinicopathologically distinctive from OKC and may thus constitute its own clinical entity.</p>
