Objective To investigate the changes of follicular regulatory T cells ( Tfr cells) and follicular T helper cells ( Tfh cells) in peripheral blood of children with myasthenia gravis ( MG) . Methods We recruited 28 MG patients and 20 healthy subjects in this study. The percentages of Tfh and Tfr cells in peripheral blood samples were measured by flow cytometry. Real-time PCR was performed to detect the ex-pression of transcription factors and regulatory factors of Bcl-6, c-MAF, Blimp-1 and PD-1 at mRNA level. ELISA was used to detect the levels of IL-2, IL-6, IL-10 and IL-21 in plasma samples and the titers of Ach-Rab and PsMab. Results Compared with the healthy subjects, the MG patients showed higher percentages of Tfh cells and lower percentages of Tfr cells before receiving treatment. The expression of Bcl-6 and c-MAF on CD4+T lymphocytes cells at transcriptional level were significantly enhanced, while the expression of Blimp-1 on CD4+T cells and the expression of PD-1 on Treg cells at transcriptional level were inhibited in the MG patients in comparison with those in healthy subjects. Moreover, decreased levels of IL-2 and increased levels of IL-21 were found in plasma samples collected from the MG patients. Conclusion The decreased percentages of Tfr cells and increased percentages of Tfh cells in patients with MG resulted in abnormal ratios of Tfr/Tfh cells, which might be involved in the immunological pathogenesis of MG. Several changes in the patients with MG might be responsible for the imbalanced ratio of Tfr/Tfh cells, which included changes of IL-2 and IL-21 in microenvironment, enhanced expression of Bcl-6 and c-MAF at mRNA level and inhibited expression of Blimp-1 at mRNA level on CD4+T cells as well as over-expression of PD-1 at mRNA level on Treg cells.

Objective To investigate the influence of IVIG on immunologic function and cytokines levels in children with EV71 infection associated high-risk pulmonary hemorrhage. Methods According to the inclu-sion criteria , 64 children were enrolled and randomly divided into two groups: 39 cases in the IVIG treatment group and 25 cases in the general treatment group. The alternations of blood and immune cytokine markers before and after treatment were detected in the patients. Results (1) Before treatment, the peripheral blood T cells, TH and B cells in the IVIG group were higher than those in the general group , but the peripheral blood IgA was lower than that in the general group(P < 0.05); (2) In the IVIG group, the NK cells and IgG increased and T cells, TH cell and B cells significantly decreased after receiving IVIG therapy (P < 0.05); (3)No significant difference was observed in the levels of IL-6 and IL-10 in the two treatment groups before treatment. However , after IVIG treatment, IL-6 and IFN-γ levels reduced, IL-10 level increased (P < 0.05). After the general treat-ment, no significant difference was found in levels of IL-6,IL-10 and IFN-γ in peripheral blood (P > 0.05). Conclusion Disorders of cellular immunity and humoral immunity appeared in children with EV71 infection-re-lated high-risk pulmonary hemorrhage. It has clinical value to use IVIG timely to regulate the immune disorder.

Objective To observe the clinical effects of L-carnitine in myocardial enzyme abnormality caused by enterovirus in children with hand foot and mouth disease (HFMD). Methods 660 HFMD children patients with myocardial enzyme abnormality from May 2013 to June 2016 were enrolled and randomly divided into three groups. Group A(n=220)was treated with 1′6-FDP,group B with L-carnitine and group C with L-carnitine combined with 1′6-FDP. All groups were given routine anti-virus and symptomatic treatment. The clinical efficacy was compared across the three groups in terms of myocardial enzyme spectrum,heart rate,ECG,severe conver-sion rate before and after treatment. Results (1)Before treatment,there was no significant difference between the three groups in gender,age,course of disease,heart rate,myocardial enzyme spectrum and other indicators. (2)After treatment,the cure rate of HFMD in group B and group C were significantly higher than that in group A (both P<0.05);the rate of severe cases and the ECG normal rate in group B and group C were significantly lower than those in group A(both P<0.05),the time for heart rate resuming to normal in group B and in group C was all significantly shorter than that in group A(both P<0.05). There were no significant differences between group B and group C in clinical cure rate,severe conversion rate,recovery rate of ECG and heart rate recovery(all P>0.05).(3)In comparison with group A,after treatment,the levels of myocardial enzyme in group A and group B were decreased significantly(P < 0.05)and the recovery rates of myocardial enzyme in group A and the group B were significantly higher (P < 0.05),but no significant difference were observed between group A and group B (P>0.05). Conclusions For HFMD children with myocardial enzyme abnormality caused by enterovirus ,L-car-nitine together with myocardial nutritional therapy can significantly improve the myocardial enzyme indexes and electrocardiogram abnormality. It reduces the rate of severe cases and improve the prognosis.

Objective To evaluate the effect of using"metronome"to guide chest compression in the new nurse training of cardiopulmonary resuscitation(CPR). Methods From 2015 to 2016,385 new nurses were enrolled and randomly by random number table divided into four groups based on Solomon four-group design:control group 1(96 nurses),sudy group 1(89 nurses),control group 2(104 nurses) and study group 2(96 nurses),Control group 1 and control group 2 accepted normal training plus "chest compressions operation formula" training,study group 1 and study group 2 got "metronome" guiding based on the frequency training.Control group 1 and study group 1 took a baseline test before the training started,while control group 2 and study group 2 didn't.Four groups took part in an operational test after the seven days of training. Results There was no statistical difference between the baseline test scores of control group 1 and study group 1(P>0.05).After the training,the score of study group 1 was 93.4±3.5, which was significantly higher than 91.6 ± 4.7 of control group 1(t=-2.870, P<0.01).Through covariance analysis,after removing the impact of the baseline test score,the score of study group was statistically significant higher than that of control group 1 (F=7.33, P=0.007).Furthermore,there was no statistically significant interaction between the baseline test score and training method (P>0.05).Meanwhile,after training,study group 2 scores was 93.5±3.5,which was statistically higher than 92.1±4.0 of control group 2(t=2.670,P=0.008).Control group 1 were combined with control 2 to form control group,as well as study group 1 with study group 2 to form study group.A comparison between these two new groups indicates that the new study group surpasses the new control group with lower error frequencies in the position,depth and frequency of external cardiac compression (t=4.701 8, 12.488 9, 11.993 9, P<0.05).In addition,the study group also showed a better performance, when taking into consideration of the region and skills of compression and the observation of complexion,while there was no statistical difference between the error frequencies in these three aspects of these two new groups(P>0.05). Conclusions In the CPR training of new nurses,using a 100 times/min"metronome"can help new nurses grasp the accurate compression rates and depth, improve the overall quality of this procedure,making it a simple and effective training method,which is worthy of popularization.

Objective:To compare the effect of extracorporeal membrane oxygenation(ECMO)on pulmonary transplantation(LTx)in patients with idiopathic pulmonary fibrosis(IPF)complicated with pulmonary hypertension(PH).Methods:From January 2017 to December 2020, clinical data were retrospectively reviewed for 112 IPF patients complicated with PH undergoing LTx assisted by venous ECMO(VV-ECMO group, n=68)or venous arterial ECMO(VA-ECMO group, n=44). Gender, age, mechanical ventilation time, oxygenation index, cold ischemic time, preoperative gender, age, smoking history, PO 2, PCO 2, PH degree, NYHA cardiac function grade, right cardiac function, ejection fraction(EF)and complications(hypertension & diabetes)of two groups were compared. Intraoperative approach, operative duration, ECMO transfer time, blood loss, blood transfusion, urine volume, postoperative blood transfusion, mechanical ventilation time, ICU stay time, re-thoracotomy, pulmonary infection, primary graft dysfunction(PGD)and renal insufficiency were recorded. And the effects of two different diversion modes on early postoperative complications and short-term outcomes of LTx were further analyzed by multiple factors. Cox proportional risk model was employed for comparing VV-ECMO and VA-ECMO flow patterns with factors related to recipient survival after transplantation. Results:The preoperative PO 2 of 58.3(51.3, 72.0)mmHg was significantly lower in VV-ECMO bypass group than that of 73.2(63.3, 96.8)mmHg in VA-ECMO group and the difference was statistically significant( P<0.006). Compared with VV-ECMO group, 24(54.5%), 15(34.1%)and 22(50.0%)had NYHA class Ⅲ, severe PH and preoperative right heart enlargement in VA-ECMO group respectively and the differences were statistically significant compared with 17(25.0%), 6(8.8%)and 16(23.5%)in VV-ECMO group( P<0.05 for all). No significant inter-group differences existed in postoperative PGD, postoperative mechanical ventilation time(≥3 d), pulmonary infection, postoperative thoracotomy ratio, postoperative renal insufficiency, ICU stay, hospital stay and other aspects( P>0.05). And 6-month postoperative survival rates of VV-ECMO and VA-ECMO groups were 80.9% and 61.4%, respectively and no significant inter-group difference existed in short-term survival rate(6 months)after adjustment by multivariate Cox regression model( P>0.05). Multivariate statistics indicated that the risk of delayed postoperative withdrawal was 14.452-fold higher in VV-ECMO group than in VA-ECMO group and the inter-group difference was statistically significant(95% CI: 2.448-85.323, P=0.03). Conclusions:No differences exist in postoperative complications or short-term survival rate between IPF recipients with mild PH on VV-ECMO mode and IPF recipients with severe PH on VA-ECMO mode. VV-ECMO flow reversal can delay the transplant back-off time.

Objective:
To explore the application value of endoscope in probing the chronic wound with sinus tract in clinic.
Methods:
Twenty-eight chronic wounds with sinus tracts from 27 patients conforming to the inclusion criteria admitted to Outpatient Department of Wound Healing Center of Ruijin Hospital from December 2017 to March 2018 were investigated in a prospective and self-controlled trial. After being cleaned, the diameter of the opening of sinus tract was measured with a rule. A probe was used to measure the depth of a sinus tract according to the touch from the probe extremity in operation, and to measure the depth of a sinus tract that could be observed with naked eyes with the help of a pair of hemostatic forceps. Five minutes later, a probe was inserted deeply into the sinus tract to measure the depth under the endoscopic view combined with touch from the probe extremity in operation. Afterwards, the sinus tract was observed with endoscope, and the depth of the tract which could be observed under the endoscopic view was measured using a probe inserted deeply into the sinus tract. After completion of the above exploration, the sinus tract was infused with contrast agent Omnipaque 350 and scanned by computed tomography (CT) later to obtain its depth. The following indicators were calculated: the ratio of the depth of the sinus tract measured by CT to the diameter of the opening of the sinus tract (hereinafter referred to as the depth/diameter ratio of the sinus tract), the deviation rate comparing the depth of the sinus tract measured by conventional method (measured by probe only) and by endoscope (measured by probe under the endoscope view) with the depth of the sinus tract measured by CT (hereinafter referred to as the deviation rate of the measured depth of the sinus tract), the deviation rate comparing the depth of the sinus tract that could be observed measured by conventional method and by endoscope with the depth of the sinus tract measured by CT (hereinafter referred to as the deviation rate of the depth of the sinus tract that could be observed). Data were processed with paired

Objective:To explore the clinical significance of serum Chromogranin A (CGA) level in predicting the prognosis of children with severe hand, foot, and mouth disease (HFMD) and complicating neurogenic pulmonary edema (NPE).Methods:A total of 162 patients with HFMD admitted in our hospital from January 2017 to December 2019 were enrolled in the study; and 40 age-matched healthy children were selected as controls. According to the disease severity and complication the patients were divided into three groups: mild group ( n=88), severe without NPE group ( n=46) and severe with NPE group ( n=28). In 72 severe HFMD patients 16 cases died (fatal group) and 56 cases survived (survival group) within 28 days of hospitalization. The serum CGA, LAC, GLU, WBC, PCT, IL-6, cTnT were measured in all subjects. SPSS 23.0 software was used for data analysis, and the receiver operating characteristic (ROC) curve was used to evaluate the various indicators for predicting the prognosis of severe HFMD combined with NPE. Results:The serum CGA, GLU, LAC, IL-6 and cTnT levels in severe HFMD group with NPE significantly higher than those in the other three group ( H=61.554, 79.031, 86.994, 36.477, 75.021, all P<0.05 ). The serum CGA, LAC, GLU and IL-6 levels in the fatal group were significantly higher than those in survival group ( Z=-6.094, -4.621, -4.283, -5.504, all P<0.05). There was no significant difference in the levels of WBC, PCT and cTnT between the survival group and the fatal group ( P>0.05). The area under the receiver operating curve (AUC) of serum CGA was 0.890 (95% CI: 0.833-0.947) for predicting the prognosis of patients and the best cut-off value was 120.59 μg/L. Conclusion:The detection of serum CGA levels may be beneficial for the early diagnosis of severe HFMD with NPE, and can be used as one of the predictors of death from severe HFMD.
