Objective To investigate the current status and influencing factors of vaccination in immunocompromised children and to provide a reference for vaccination strategy in these children.Methods Wenjuanxing questionnaire investigation was carried out in the parents of immunocompromised children who visited the Department of Hematology,Shanghai Children's Medical Center and the Department of Liver Transplant,Renji Hospital from December 2018 to January 2020,of which the content included the basic information of immunocompromised children as well as vaccination status and intention.Results The ages of the immunocompromised children were(6.29±4.09) years.A total of 296(48.9%) children were vaccinated after illness,while 309(51.1%) were unvaccinated.The mainly influencing factors of vaccination in immunocompromised children included low family income(χ~2=20.381,P <0.001),type of disease(solid tumor)(χ~2=29.486,P <0.001),low willingness to vaccination after treatment(χ~2=21.462,P <0.001),reduced going out of children(χ~2=9.035,P=0.003),stable condition of children and low enthusiasm of the parents to vaccination(χ~2=26.394,P <0.001).Conclusion Vaccination coverage is relatively low in immunocompromised children,of which the mainly influencing factors included low family income as well as low willingness and low enthusiasm to vaccination after treatment.Publicity and education on vaccination-related knowledge should be strengthened to improve the vaccination awareness of the parents.

Objective To observe the effect of acupuncture plus rehabilitation on the development quotient in patients with mental retardation (MR) and its therapeutic efficacy by using the Neural and Mental Development Check List for Children Aged 0-6. Method Sixty MR patients were divided into a treatment group and a control group by the random number table, 30 cases in each group. The treatment group was intervened by acupuncture plus rehabilitation training, while the control group was by rehabilitation alone. The improvement of development quotient and therapeutic efficacy were evaluated after 3 treatment courses. Result The improvement of development quotient in the treatment group was more significant than that in the control group; the total effective rate was 83.3% in the treatment group versus 73.3% in the control group, and the difference was statistically significant (P<0.05). Conclusion Acupuncture plus rehabilitation training can produce a more significant efficacy than rehabilitation alone in treating MR.

Objective To study the relationship between serum uric acid (UA) level and cerebrovascular stenosis in acute ischemic stroke (AIS) patients.Methods Five hundred and thirteen patients with AIS or old IS admitted to our hospital from April 2014 to April 2016 were divided into primary IS group (n=236),recurrent IS group (n=136),and old IS group (n=141).Venous blood samples were taken on admission for biochemical testing.The patients were further divided into serum UA≤255 μmol/L group (n=128),serum UA=256-312μmol/L group (n=129),serum UA=313-371 μmol/L group (n=129),and serum UA＞371 μmol/L group (n=127).Their cerebrovascular stenosis was assessed by CT angiography or magnetic resonance angiography after admission.Results The severity of cerebrovascular stenosis,hypertension,diabetes and hyperlipidemia was significantly different in primary IS group,recurrent IS group and old IS group (27.5％ vs 33.8％ vs 12.8％、24.2％ vs 28.7％ vs 46.8％、61.9％ vs 49.3％ vs 40.4％、71.6％ vs 61.8％ vs 46.8％,P=0.000).Logistic regression analysis showed that serum UA≤ 255 μmol/L was an independent risk factor for cerebrovascular stenosis (OR =2.787,95 ％CI:2.209-3.365,P=0.001).The risk of cerebrovascular stenosis decreased gradually with the elevated serum UA level.Conclusion Serum UA level is not directly related with recurrent IS.Low serum UA level is a risk factor for cerebrovascular stenosis in AIS.

OBJECTIVE:To evaluate the role of PDCA cycle management on standardizing clinical use of atomization inhala-tion drug. METHODS:Using a retrospective method,300 medical records of atomization inhalation drug use were collected from our hospital during Jan.-Dec. in 2013(non-intervention group),200 medical records collected during Apr.-Jun. in 2014(one cycle intervention group),and 180 medical records collected during Oct.-Dec. in 2014(two rounds of cycle intervention group). The use of atomization inhalation drugs was compared before and after the application of PDCA cycle management. Before and after two cy-cle intervention,4 types of medical staff were investigated on cognition of the related knowledge of atomization inhalation drugs, as physicians,pharmacists,nurses and mechanic. RESULTS:After two rounds of PDCA cycle management and intervention,the proportion of unsuitable route of administration of antibiotics,long acting glucocorticoid,non-atomization inhalation dosage form of resolving phlegm drugs,protease decreased from 54.0%,62.0%,59.7%,44.7% before intervention to 0.6%,1.1%,15.0%, 1.1% after intervention;those phenomena had not been found,such as unsuitable route of administration of TCM injection and non-atomization dosage form of theophyllines,unsuitable atomization frequence,unsuitable indication,drug mixture for preventing and controlling symptom,etc. The proportion of medical staffs being familiar with medical device,drug classification,drug selec-tion for prerention and treatment and the proportion of hospital drug stock to 93.4%,86.7%,92.4%,96.2% after intervention from 38.0%,79.0%,49.0%,39.5%before intervention. CONCLUSIONS:The application of PDCA cycle management can effec-tively regulate the use of atomization inhalation drugs in our hospital;the method can be promoted and applied.

OBJECTIVE: To observe the correlation between the threshold of tone burst auditory brain stem response (Tb-ABR) and ASSR (auditory steady-state response) and the threshold of BA (behavioral audiometry). To investigate the accuracy and clinical value of Tb-ABR and ASSR in pediatric hearing assessment. METHOD: From January, 2014 to December, 2014, 76 children (123 ears) recieved hearing examination in the First Affiliated Hospital of Zhengzhou University. They were classified into three groups according to the hearing level: 23 children (46 ears) with normal hearing ability in group A, 27 children (32 ears) with slightly-moderate sensorineural deafness in group B and 26 children (45 ears) with severe-profound sensorineural deafness in group C. Tb-ABR, ASSR, BA in 4 frequencies (0.5, 1.0, 2.0, 4.0 kHz) were tested and the results were statistically analyzed. RESULT: (1) At the 4 frequencies (0.5-4.0 kHz), we obtained 132 thresholds of Tb-ABR, 144 of ASSR, 152of BA. And 166 thresholds were obtained in Tb-ABR+ASSR+BA in total . (2) The thresholds of Tb-ABR, ASSR and those of BA in all 3 groups had linear relations at 0.5-4.0 kHz. The correlation coefficients of group A were 0.76, 0.82, 0.87 and 0.91; 0.52, 0.57, 0.67 and 0.64. Those of Group B were 0.89, 0.95, 0.98 and 0.95; 0.74, 0.82, 0.87 and 0.90. Those of Group C were 0.91, 0.90, 0.92 and 0.89; 0.93, 0.95, 0.95 and 0.91. CONCLUSION (1) Both ASSR and Tb-ABR can allow reasonably accurate predictions for the pediatric hearing assessment. The correlation between Tb-ABR threshold and BA threshold is higher in normal hearing children and slightly-moderate sensorineural deafness children. The correlation between ASSR threshold and BA threshold is higher in severe-profound sensorineural deafness children. (2) The hearing test combination can evaluate the residual hearing ability for children with severe hearing loss.

Objective To analyze the related influencing factors of progressive ischemic stroke, and to investigate the value of serum markers for prediction of progressive ischemic stroke. Methods Three hundred and six patients with acute cerebral infarction were divided into progressive ischemic stroke (PIS) group (n=91) and non-progressive ischemic stroke (NPIS) group (n=215). Data of gender, age, past medical history, personal history and serum markers were collected and compared in two groups. Binary Logistic regression was used to analyze the influencing factors of PIS. The receiver operating characteristic (ROC) curves of neutrophils to lymphocytes ratio (NLR), fibrinogen and fasting blood glucose were analyzed in two groups. Results Positive rates of hypertension history, diabetes history, hypercholesterolemia history, incidence of large artery atherosclerotic (LAA) stroke were significantly higher in PIS group than those in NPIS group ( P<0.05). The levels of neutrophils, NLR, fibrinogen and fasting blood glucose were significantly higher, but the level of lymphocytes was significantly lower in patients with PIS than those in patients with NPIS (P<0.05). Logistic regression analysis confirmed that diabetes, LAA stroke, NLR, fibrinogen and fasting blood glucose were independent risk factors for the PIS ( P<0.05). The areas under ROC curve by NLR, fibrinogen and fasting blood glucose were 0.777, 0.560 and 0.574, respectively. The sensitivities of NLR, fibrinogen and fasting blood glucose were 72.5%, 59.8%and 47.3%, respectively;and the specificities were 76.7%, 51.2% and 69.8%, respectively. Conclusion The occurrence of PIS is related with blood pressure, blood lipids, inflammatory cells in peripheral bolld, fibrinogen and fasting blood glucose. The level of NLR in peripheral blood can predict the occurrence of PIS, which can be used as an important reference index for early diagnosis of PIS.
