Objective: To compare the effects of the China Children's Asthma Action Plan (CCAAP)-based remote joint management model with traditional management model on the control of childhood asthma. Methods: A retrospective cohort study was conducted to analyze the general data and asthma control assessment data of 219 children with asthma who attended the respiratory department of Guangzhou Women's and Children's Medical Center from April 2021 to October 2021 and were followed up for 1 year or more. According to the follow-up management model, the CCAAP-based remote joint management model was used in the observation group and the traditional management model was used in the control group, and the propensity score matching method was applied to match the data of children in the two management models for comparison. Paired-samples t-test, Wilcoxon signed-rank test, McNemar χ²-test or χ²-test or nonparametric tests were used to compare the general data and asthma control assessment data between the two matched groups of children. Results: Among 219 children with asthma, 145 were male and 74 were female, aged at consultation (7.2±2.4) years. There were 147 cases in the observation group and 72 cases in the control group, and 27 cases in each of the observation and control groups were successfully matched. The number of asthma exacerbation aura, acute exacerbations, and emergency room visits or hospitalizations for asthma exacerbations were lower in the observation group than in the control group after pairing (1 (0, 2) vs. 3 (1, 5) times, 0 (0,0) vs. 0 (0, 1) times, 0 (0,0) vs. 1 (0, 1) times, Z=-3.42, -2.58, -3.17, all P<0.05). The use of peak flowmeters was higher in children aged 5 years and older in the observation group than in the control group after pairing (100% (22/22) vs. 13% (3/23), χ²=54.00,P<0.001). The ratio of actual to predicted 1st second expiratory volume of force after follow-up in the observation group after pairing was higher than that before follow-up in the observation group and after follow-up in the control group ((95±11)% vs. (85±10)%, (95±11)% vs. (88±11)%, t=-3.40, 2.25, all P<0.05). The rate of complete asthma control after follow-up was higher in both the observation and control groups after pairing than before follow-up for 12 months in both groups (93% (25/27) vs. 41% (11/27), 52% (14/27) vs. 41% (11/27), H=56.19, 45.37, both P<0.001), and the rate of complete control of asthma in children in the observation group was higher than that in the control group at 3 and 12 months of follow-up management (56% (15/27) vs. 25% (5/20), 93% (25/27) vs. 52% (14/27), χ²=47.00, 54.00, both P<0.001). The number of offline follow-up visits, inhaled hormone medication adherence scores, and caregiver's asthma perception questionnaire scores were higher in the observation group than in the control group after pairing (6 (4, 8) vs. 4 (2,5), (4.8±0.3) vs. (4.0±0.6) score, (19.3±2.6) vs. (15.2±2.7) score, Z=6.58, t=6.57, 5.61, all P<0.05), and the children in the observation group had lower school absences, caregiver absences, asthma attack visit costs, and caregiver PTSD scores than the control group (0 (0,0) vs.3 (0, 15) d, 0 (0,0) vs. 3 (0, 10) d, 1 100 (0, 3 700) vs. 5 000 (1 000, 10 000) yuan, 1.3 (1.1, 1.9) vs. 2.0 (1.2, 2.7) score, Z=-2.89, -2.30, 2.74, 2.73, all P<0.05). Conclusion: The CCAAP-based joint management model of asthma control is superior to the traditional management model in the following aspects: it can effectively improve asthma control, self-monitoring, and lung function in children; it can improve treatment adherence and caregivers' asthma awareness; and it can reduce the duration of absenteeism from school, the cost of asthma exacerbation visits, and caregiver's negative psychology.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Objective: To investigate the incidence and prognosis of tricuspid regurgitation after transcatheter closure of perimembranous ventricular septal defects in pediatric patients as well as the risk factors of regurgitation occurrence or aggravation. Methods: Clinical data of 1 108 patients who underwent percutaneous closure in Shanghai Children′s Medical Center, School of Medicine, Shanghai Jiaotong University from January 2011 to January 2017 was analyzed retrospectively, and the prognosis and risk factors of postoperative tricuspid regurgitation and aggravation were also analyzed. Results: Mild tricuspid regurgitation occurred in 24 cases after surgery with the incidence of 2.1%.Among 5 cases with mild or above preoperative tricuspid regurgitation, the regurgitation was alleviated after surgery in 4 cases.No severe tricuspid regurgitation requiring surgical intervention occurred in any patient during follow-up.Univariate analysis showed that intervention time (P<0.05) and residual shunt (P<0.05) were risk factors for mild or above tricuspid regurgitation after intervention.Binary regression analysis indicated that the size of the occluder (mm) (OR=1.48, 95%CI: 1.13-1.90) and residual shunt (OR=6.53, 95%CI: 1.69-25.30) were risk factors for tricuspid regurgitation after intervention (all P<0.05). Conclusions There is a certain incidence of tricuspid regurgitation after transcatheter closure of perimembranous ventricular septal defects, but most tricuspid regurgitation do not need surgical intervention.The intervention time, size of occluder and residual shunt are risk factors of intraoperatively or postoperatively tricuspid regurgitation.

Objective:To explore the expression and significance in regulating immune balance of programmed cell death protein 1 (PD-1) and its ligands PD-L1, PD-L2 in allergic rhinitis (AR).Methods:Eighty-two patients who received outpatient treatment due to high nasal reaction symptoms or were hospitalized due to nasal septum deviation and underwent nasal septum correction surgery in Department of Otorhinolaryngology Head and Neck Surgery of Renmin Hospital of Wuhan University from May 2018 to May 2019 were enrolled, including 42 males and 40 females, with the age ranging from 14 to 38 years old. Blood, inferior turbinate nasal mucosal tissue and relevant clinical data were collected. Patients were divided into AR group and control group due to clinical manifestation, skin prick test and detection of specific IgE (sIgE) in serum. Immunohistochemistry was used to detect the expression of PD-1 and its ligands in nasal mucosa of the two groups. Flow cytometry was used to detect the proportions of PD-1 +CD4 +T cells, PD-L1 + myeloid dendritic cells (mDCs), PD-L2 +mDCs and Th2 cells in peripheral blood of the two groups. The expression levels of total IgE, sPD-1, sPD-L1 and sPD-L2 in serum of the two groups were detected by ELISA. The measurement data of normal distribution or normal distribution after the logarithm conversion to Ln were compared by t test. Pearson correlation or Spearman correlation was used to analyze the correlation among the indicators. P<0.05 was considered statistically significant. Results:The expression of PD-1 and its ligands on the surface of immune cells in the nasal mucosa of the AR group was significantly higher than that of the control group. The ratio of PD-1 +CD4 +T cells, PD-L1 +mDCs and Th2 cells in peripheral blood of AR group was significantly higher than that of the control group ((15.24±6.45)% vs (8.71±5.33)%, (8.79±2.01)% vs (5.74±2.90)%, (7.89±1.95)% vs (2.52±1.34)%, all P<0.05). There was no significant difference in the ratio of PD-L2 +mDCs between the two groups. Correlation analysis found that the proportion of PD-1 +CD4 + T cells was positively correlated with the Visual Analogue Scale (VAS) score of AR, total IgE concentration and the serum sIgE concentration ( r value was 0.501, 0.541, 0.608, respectively, all P<0.05). The proportion of PD-L1 +mDCs was positively correlated with the VAS score of AR and the serum sIgE concentration ( r value was 0.604, 0.563, respectively, all P<0.05). The proportion of Th2 cells in peripheral blood was positively correlated with the proportion of PD-L1 +mDCs and PD-1 +CD4 +T cells ( r value was 0.538, 0.623, respectively, all P<0.05). Serum total IgE, sPD-1 and sPD-L1 in the AR group were significantly higher than those in the control group ((6.34±1.38) ng/ml vs (4.89±1.10) ng/ml, (4.40±1.01) pg/ml vs (3.79±1.21) pg/ml, (3.88±0.25) pg/ml vs (3.57±0.23) pg/ml, all P<0.05), and there was no significant difference in sPD-L2 levels between the two groups. Correlation analysis showed that sPD-L1 was positively correlated with total IgE and sIgE concentration ( r values was 0.32, 0.45, respectively, all P<0.05). Conclusions:PD-1 and PD-L1 are highly expressed on the surface of immune cells in peripheral blood and nasal mucosa of AR patients, and sPD-1 and sPD-L1 expression levels in peripheral blood of AR patients are increased. The PD-1/PD-L1 signaling pathway promote AR inflammatory response by inducing Th2 type immune response.

Objective To investigate the distribution and drug resistance of carbapenem-resistant Enterobacteriaceae ( CRE) isolated from children in China. Methods CRE strains were collected in 10 ter-tiary children's hospitals of China from January 1, 2016 to December 31, 2017. Antimicrobial susceptibility of the clinical strains was detected with disk diffusion method ( KB method) and automated method. The re-sults were analyzed according to the Clinical and Laboratory Standards Institute ( CLSI) Standards published in 2017. WHONET 5. 6 software was used to retrospectively analyze the distribution characteristics and drug resistance of these strains. Results A total of 3065 CRE clinical strains were isolated from children with an overall prevalence of 7. 7％ and among them, 13. 5％ were isolated in neonatal group and 5. 8％ in non-neo-natal group. The detection rate of CRE in 2017 was higher than that in 2016 (9. 7％ vs 5. 7％). Among the 3065 CRE strains, there were 1912 strains of Klebsiella pneumoniae (62. 0％), 667 strains of Escherichia coli (22. 0％), 206 strains of Enterobacter cloacae (7. 0％), 56 strains of Klebsiella aerogenes (1. 8％) and 47 strains of Serratia marcescens (1. 5％). Most of the strains were isolate in neonatology departments including neonatal intensive care units (NICU) and intensive care units (ICU), accounting for 44. 8％ and 19. 7％, respectively. Respiratory tract (61. 8％), urine (19. 4％) and blood (5. 7％) specimens were the main sources of CRE isolates. Results of antimicrobial susceptibility test showed that the CRE strains were highly resistant to carbapenem antibiotics such as imipenem, meropenem and ertapenem, as well as penicillins and most cephalosporins (79. 6％-100％), especially those isolated in the neonatal group (P<0. 05). Children had relatively low resistance rates to aminoglycosides such as amikacin (19. 7％) and fos-fomycin (11. 9％), fluoroquinolones such as levofloxacin (37. 7％) and ciprofloxacin (43. 3％), and tige-cycline (3. 8％). Currently, no polymyxin B-resistant strains were isolated. Conclusions The prevalence of common CRE strains in children in 2017 was higher than that in 2016, especially in newborns. Drug re-sistance in CRE strains isolated from neonates to common antibiotics was more severe, suggesting that great attention should be paid to it and timely measures should also be taken.

OBJECTIVETo detect RAS mutations in the circulating cell-free DNA (cfDNA) in the plasma and explore the their correlation with the clinicopathological features in patients with colorectal cancer.

METHODSReal-time PCR was used to detect RAS mutations in plasma cfDNA and matched tumor tissue DNA samples from 71 colorectal cancer patients. The correlation of RAS mutations with the clinicopathological features of the patients were analyzed.

RESULTSOf the 71 patients with colorectal cancer, 23 (32.39%) showed RAS mutations in the cfDNA and 36 (50.7%) showed RAS mutations in tumor tissue DNA, with a concordance rate of 76.06% in the results between the two samples (Kappa=0.523). RAS mutations in the cfDNA were not related to the patients' age (P=0.072), gender (P=0.320), tumor stage (IVa and IVb, P=0.450), primary tumor position (P=0.324), lung metastasis (P=0.237), CEA level (P=0.284) or CA199 level (P=0.427). The positivity rate of RAS mutations in plasma cfDNA was significantly higher in patients with liver metastasis than those without liver metastasis (P=0.045).

CONCLUSIONPlasma cfDNA can be a reliable source of diagnostic DNA to replace the tumor tissue DNA for diagnosis of RAS mutations. RAS mutations in plasma cfDNA occur more frequently in colorectal cancer patients with liver metastasis.

BACKGROUNDDecreased platelet (PLT) count is one of the independent risk factors for mortality in intensive care unit (ICU) patients. This study was to investigate the relationship between PLT indices and illness severity and their performances in predicting hospital mortality.

METHODSAdult patients who admitted to ICU of Changzheng Hospital from January 2011 to September 2012 and met inclusion criteria were included in this study. Univariate analysis was used to identify potential independent risk factors for mortality. Multiple logistic regression analysis was used to calculate adjusted odds ratio for mortality in patients with normal or abnormal PLT indices. The relationship between PLT indices and illness severity were assessed by the Acute Physiology and Chronic Health Evaluation II (APACHE II) scores or sequential organ failure assessment (SOFA) scores in patients with normal and abnormal PLT indices. The performances of PLT indices in predicting mortality were assessed by receiver operating curves and diagnostic parameters. The survival curves between patients with normal and abnormal PLT indices were compared using Kaplan-Meier method.

RESULTSFrom January 2011 to September 2012, 261 of 361 patients (204 survivors and 57 nonsurvivors) met the inclusion criteria. After adjustment for clinical variables, PLT count <100 × 10 12 /L (P = 0.011), plateletcrit (PCT) <0.108 (P = 0.002), mean platelet volume (MPV) >11.3 fL (P = 0.023) and platelet distribution width (PDW) percentage >17% (P = 0.009) were identified as independent risk factors for mortality. The APACHE II and SOFA scores were 14.0 (9.0-20.0) and 7.0 (5.0-10.5) in the "low PLT" tertile, 13.0 (8.0-16.0) and 7.0 (4.0-11.0) in the "low PCT" tertile, 14.0 (9.3-19.0) and 7.0 (4.0-9.8) in the "high MPV" tertile, 14.0 (10.5-20.0) and 7.0 (5.0-11.0) in the "high PDW" tertile, all of which were higher than those in patients with normal indices. Patients with decreased PLT and PCT values (all P < 0.001), or increased MPV and PDW values (P = 0.007 and 0.003, respectively) had shortened length of survival than those with normal PLT indices.

CONCLUSIONSPatients with abnormally low PLT count, high MPV value, and high PDW value were associated with more severe illness and had higher risk of death as compared to patients with normal PLT indices.

Objective To evaluate the feasibility and therapeutic efficacy of real-time virtual navigation system (RVS) combined with contrast-enhanced ultrasonography (CEUS) for hepatocellular carcinoma undetectable by conventional ultrasound and CEUS.Methods A total of 213 patients with 265 lesions (undetectable on conventional ultrasound but detectable by other imaging examinations) were enrolled in this study.CEUS was performed,and lesions which were detected with CEUS were given CEUS guided radio-frequency ablation (RFA) (CEUS group).RVS combined with CEUS was performed to locate the rest lesions and guide RFA (RVS + CEUS group).Diagnostic value and therapeutic efficacy of RVS + CEUS were assessed.Results In 256 lesions,174 (65.7％) could be detected with CEUS,and among the rest 91 lesions,82 (90.1％) lesions could be detected by RVS combined with CEUS.The technique effectiveness rate of RVS + CEUS was significantly higher than that of CEUS (x2 =18.85,P ＜0.0001).Complete ablation rate after one month in RVS+ CEUS group was 9t.5％ (75/82),which was significantly higher than that in CEUS group [86.2％ (150/174),P ＜0.05].Local progression in one year in CEUS group and RVS + CEUS group were 13.4％ and 10.9％,respectively.Conclusions RVS combined with CEUS is feasible for hepatocellular carcinoma undetectable by conventional ultrasonography and CEUS,and the therapeutic efficacy of RVS + CEUS guided RFA is satisfactory.

OBJECTIVETo compare efficacy differences between fire filiform needle combined with mild moxibustion and gabapentin combined with sham acupuncture for postherpetic neuralgia (PHN).

METHODSOne hundred cases of PHN were randomly divided into a needle group and a medicine group, 50 cases in each one. In the needle group, pricking method of fire filiform needle was given at the Ashi points, and then mild moxibustion was applied for 15 min. In the medicine group, the oral administration of gabapentin capsule and sham acupuncture at non-acupoints in the distal end of lesions were applied. The treatment was required for 21 days in both groups. The visual analogue score (VAS) was recorded before treatment and on the 1st day, 2nd day, 3rd day, 6th day, 9th day and 12th day of treatment. The most severity of pain within last 24 h, preset severity of pain, immediate analgesia effect and starting time of pain relief were observed, also the efficacy was assessed and improvement of symptoms was observed in the follow-up visit.

RESULTSThe total effective rate was 94.0% (47/50) in the fire filiform needle group, which was superior to 86.0% (43/50) in the medicine group (P < 0.05). Compared with medicine group, the VAS of the most severity of pain within last 24 h was obviously reduced after the 2nd treatment in the fire filiform needle group while that of present severity of pain was relieved after the 1st treatment (both P < 0.05). The immediate analgesia effect in the fire filiform needle group was obviously superior to that in the medicine group in the first three times of treatment (all P < 0.05). The average time of pain relief was (3.91 +/- 0.82) days in the fire filiform needle group, which was significantly earlier to (6.53 +/- 1.13) days in the medicine group (P < 0.05). 26 cases were cured in the fire filiform needle group in the follow-up visit, which was superior to 2 cases in the medicine group (P < 0.05). The improvement of VAS, pain range and sleep quality in the needle group were also superior to those in the medicine group (all P < 0.05). The direct medical cost in the fire filiform needle group was (232.32 +/- 48.108) yuan, which was significantly lower than (466.00 +/- 41.09) yuan in the medicine group (P < 0.05). There was only one case of adverse effect in the medicine group during the treatment.

CONCLUSIONThe fire filiform needle combined with mild moxibustion could obviously relieve the pain in PHN patients, which has superior immediate analgesia effect and pain relieving time compared with gabapentin, which also has less adverse effects and cheap cost.
