Objective:To explore the clinical effect of vitamin A in the adjuvant treatment of bronchial asthma in children and its influence on serum transforming growth factor-β1 (TGF-β1), eosinophils (EOS) and interleukin-17 (IL-17) levels.Methods:A prospective study was conducted on 110 children with bronchial asthma who received treatment in Department of Pediatrics, Xi'an Central Hospital from January 2022 to December 2023. Based on the principle of balanced and comparable baseline characteristics between groups, they were randomly divided into a control group and an observation group, with 55 cases in each group, using a random number table method. The control group was treated with routine pediatric bronchial asthma therapy, while the observation group was added with vitamin A adjuvant therapy on the basis of the control group. After 15 days of continuous treatment, the scores of asthma control condition (Childhood-Asthma Control Test (C-ACT), Asthma Control Questionnaire (ACQ)) in the two groups were evaluated. The pulmonary ventilation function (forced expiratory volume in one second (FEV 1), forced expiratory volume in one second/forced vital capacity (FEV 1/FVC), peak expiratory flow (PEF)), serum inflammatory factors (TGF-β1, EOS, IL-17) and immune function indicators (T helper 17 cell (Th17), T helper 2 cell (Th2), regulatory T cell (Treg) ) were compared between groups of children before treatment and after 15 days of treatment. Measurement data with normal or approximate distribution were expressed as xˉ± s, and independent sample t test was used for comparison between groups. Enumeration data were expressed as percentage, and chi-square test was adopted for between-group comparison. Results:After 15 days of treatment, the C-ACT score with (16.20±3.14) points in observation group was higher than (14.80±2.62) points in control group while the ACQ score with (30.30±4.14) points was lower than (34.60±6.23) points in control group, with statistical differences between groups (t values were 2.54 and 4.26; P values were 0.012 and <0.001). The pulmonary ventilation function indicators in observation group and control group after 15 days of treatment (FEV 1: (1.76±0.34) L与(1.54±0.32) L, FEV 1/FVC:(76.89±5.76)%与(70.25±6.42)%, PEF(2.89±0.35) L/s与(2.68±0.39) L/s) were higher than those before treatment (FEV 1:(1.12±0.31) L与(1.20±0.33) L, FEV 1/FVC:(56.96±4.35)%与(58.12±3.48)%, PEF(2.15±0.66) L/s与(2.34±0.56) L/s), and the differences were statistically significant ( t values were 10.32, 5.49, 20.48, 10.43, 7.35, 3.70, respectively; all P<0.001), and the indicators in observation group were higher compared to control group, the differences were statistically significant ( t values were 3.49, 5.71, and 2.97; P values were 0.001, <0.001, and 0.004). After 15 days of treatment, the levels of serum inflammatory factors (TGF-β1:(6.32±1.36) ng/L与(8.75±1.81) ng/L, EOS:(3.56±0.65)%与(4.28±0.82)%, IL-17:(5.53±1.22) ng/L与(6.42±1.51) ng/L) and CD4 + T lymphocyte immune function indicators (Th17:(0.97±0.26) ng/L与(1.23±0.35) ng/L, Th2:(2.32±0.64) ng/L与(3.15±0.52) ng/L, Treg:(5.41±0.76) ng/L与(5.86±0.23) ng/L ) were lower in observation group and control group than those before treatment (TGF-β1: (14.35±2.23)与(15.26±3.05) ng/L, EOS: (6.32±1.33)%与(6.41±1.27)%, IL-17:(8.86±1.68)与(9.03±1.89) ng/L, Th17:(1.82±0.75)与(1.67±0.68) ng/L, Th2:(4.15±1.49)与(3.98±1.28) ng/L, Treg: (7.26±1.35)与(6.92±1.72) ng/L), and the differences were statistically significant ( t values were 22.80, 13.61, 13.83, 10.45, 11.90, 8.08, 7.94, 4.27, 8.37, 4.46, 8.86, 4.58, respectively; all P<0.001).

Peripheral T-cell lymphoma (PTCL) is a relatively common subtype of non-Hodgkin lymphomain in China. PTCL is clinically highly aggressive, and it progresses rapidly. The current treatment methods are ineffective and the overall prognosis is poor, especially in patients with relapsed and/or refractory. In recent years, the treatment of phosphatidylinositol 3-kinase (PI3K) inhibitors has developed rapidly, which can effectively improve the prognosis of patients with relapsed and/or refractory PTCL. This article reviews the therapeutic mechanism, effectiveness and safety of PI3K inhibitors in the treatment of relapsed and/or refractory PTCL.

Objective:To explore the application effect of improved fingertip localization guided vascular puncture method in radial artery blood sampling.Methods:Using the convenience sampling method, patients receiving radial artery blood sampling for blood gas analysis in Department of Respiratory and Critical Care Medicine of First Affiliated Hospital of Nanjing Medical University from August to November 2020 were selected as research objects. The 44 patients whose blood was collected from August to September were used as the control group, and 44 patients whose blood was collected from October to November were used as the experimental group. The control group used conventional arterial puncture to collect blood from the radial artery, while the experimental group used modified fingertip localization guided vascular puncture to collect blood from the radial artery. The success rate of first puncture, duration of puncture, pain score during puncture and incidence of immediate complications after puncture were compared between the two groups. The t test and χ 2 test were used for statistical analysis. Results:The first success rate of radial artery puncture of patients in the experimental group (81.82%) was higher than that in the control group (56.82%) . The puncture time in the experimental group was (34.600±2.442) s, which was lower than (39.156±2.785) s in the control group. The pain score of the experimental group was (3.750±0.315) , which was lower than (4.318±0.306) of the control group. All the differences were statistically significant ( P<0.05) . There were no immediate complications after puncture in the experimental group and 2 cases in the control group. There was no statistically significant difference between the two groups ( P>0.05) . Conclusions:The improved fingertip localization guided vascular puncture method can increase the success rate of the first radial artery puncture, shorten the puncture time and reduce the pain of patients.

Objective:To explore the expression levels of aldehyde dehydrogenase 1 (ALDH1) and ATP-binding cassette superfamily G member 2 (ABCG2) in non-small cell lung cancer (NSCLC) tissues, and to observe the correlations of their expressions with clinicopathological features and prognosis of patients.Methods:The tissue samples from 82 patients with NSCLC who underwent surgical treatment from January 2016 to November 2018 in Taishan Hospital of Shandong Province were selected. The expressions of ALDH1 and ABCG2 in fresh cancer tissues and adjacent tissues were detected by immunohistochemistry. χ 2 test was used to analyze the correlations of ALDH1 and ABCG2 expressions with clinicopathological features of patients; Pearson method was used to analyze the correlation between ALDH1 and ABCG2; Kaplan-Meier method and log-rank test was used to analyze the correlations of ALDH1 and ABCG2 expressions with the overall survival (OS) of patients; Cox proportional hazards model was used to analyze the influencing factors of OS. Results:The positive expression rates of ALDH1 and ABCG2 in NSCLC tissues were higher than those in adjacent tissues, and the differences were statistically significant [60.98% (50/82) vs. 12.19% (10/82), 51.22% (42/82) vs. 3.66% (3/82), χ 2 values were 42.051 and 46.582, both P < 0.01]. ALDH1 expression was positively correlated with ABCG2 expression in NSCLC tissues (P < 0.05). The positive expression rates of ALDH1 and ABCG2 in patients with TNM stage Ⅱ-Ⅲ were higher than those in patients with stage Ⅰ [70.00% (35/50) vs. 46.88% (15/32), 60.00% (30/50) vs. 37.50% (12/32), both P < 0.05], and the positive expression rates of ALDH1 and ABCG2 in patients with lymph node metastasis were higher than those in patients without metastasis [75.00% (27/36) vs. 50.00% (23/46), 66.67% (24/36) vs. 39.13% (18/46), both P < 0.05]. The median follow-up time was 22.5 months, a total of 2 patients were lost to follow-up, and the median OS time was 25.4 months. The OS rate of ALDH1-positive patients was lower than that of ALDH1-negative patients (χ 2 = 5.124, P = 0.031), and the OS rate of ABCG2-positive patients was lower than that of ABCG2-negative patients (χ 2 = 6.969, P = 0.008). Multivariate Cox analysis showed that age (OR = 1.241, 95% CI 1.021-2.535, P = 0.045), lymph node metastasis (OR = 1.521, 95% CI 1.102-4.281, P = 0.012), TNM stage (OR = 2.104, 95% CI 1.289-6.150, P = 0.018), ALDH1 (OR = 2.435, 95% CI 1.214-8.654, P = 0.001), and ABCG2 (OR = 1.503, 95% CI 1.148-5.696, P = 0.021) were independent influencing factors of OS for patients with NSCLC. Conclusions:The expressions of ALDH1 and ABCG2 in NSCLC tissues are increased, and they are associated with lymph node metastasis and TNM staging. The OS rate in ALDH1-positive and ABCG2-positive patients is low. ALDH1 and ABCG2 may be prognostic markers for NSCLC.

Objectives To investigate the effects of phytosterol intensive diet intervention on blood glucose, blood lipid and liver function in patients with type 2 diabetes mellitus combined with nonalcoholic fatty liver disease(NAFLD). Methods Patients with NAFLD admitted to the department of endocrinology, the Affiliated Hospital of Jiangsu University from January 2016 to June 2016 were recruited.We divided the groups according to the order of patient admission,with patients admitted from January to March who received conventional diabetes mellitus low-fat diet enrolled as control group,and patients admitted from April to June received extra phytosterol intensive diet on the basis of conventional diabetes mellitus diet as treatment group. The changes of blood glucose, blood lipid and liver function between two groups with a follow-up of six months before and after intervention were compared and analyzed. Results After intervention,the levels of fasting blood sugar(FPG)and blood glucose(2hPG), glycosylated hemoglobin (HbA1c), cholesterol (TG), triglyceride (TC), alanine aminotransferase (ALT) of patients in control group(11.13 ± 3.17)mmol/L,(18.65 ± 6.21)mmol/L,(9.82 ± 1.69)%,(2.81 ± 1.43) mmol/L、(5.40 ± 1.14)mmol/L,77.27%(51/66),which were lower than those before intervention((8.51 ± 2.83)mmol/L,(10.39 ± 3.62)mmol/L,(7.78 ± 1.46)%,(2.18 ± 1.13)mmol/L,(4.99 ± 1.04)mmol/L, 90.91%(60/66),P<0.05,and FPG,2 hPG,HbA1c,TG,TC,LDL-C,ALT and aspartate aminotransferase (AST) in the experimental group were(11.32 ± 3.64)mmol/L,(20.09 ± 4.83)mmol/L,(9.70 ± 2.12)%, (2.68 ± 1.74)mmol/L,(5.16 ± 1.10)mmol/L,(3.18 ± 0.92)mmol/L,(70.27)%(52/74),(86.49)%(64/74), which were significantly lower than those before intervention((7.37 ± 2.08)mmol/L,(9.20 ± 3.35)mmol/L, (6.75 ± 0.99)%,(1.86 ± 1.13)mmol/L,(4.69 ± 1.06)mmol/L,(2.67 ± 0.72)mmol/L, 91.89%(68/74), 98.65%(73/74), P<0.05, and the differences was statistically significant(t=4.584,9.329,7.349,2.823, 2.140,χ2=4.587, P<0.01 or 0.05 in control group;t=8.106,15.715, 10.826,3.393,2.651,3.755,P<0.01 in experimental group). The levels of FPG, 2 hPG and HbA1c were significantly lower in the experimental group compared with those in control group after intervention(P<0.05),and the positive-to-negative rate of fatty liver were found to be significantly higher (33.8%,25/74) than that (9.1%,6/66) in controls(P<0.05).There were not significantly differences in the level of TG,TC,high density lipoprotein(HDL-C), LDL-C, ALT and AST between the control group and experimental group(P>0.05). Conclusions Phytosterol intensive diet intervention can effectively reduce LDL-C,AST and the blood glucose level of type 2 diabetes patients with NAFLD, improving the positive-to-negative rate of fatty liver. Phytosterol intensive diet intervention can effectively reduce LDL-C, AST and the blood glucose level of type 2 diabetes patients with NAFLD,improve the positive-to-negative rate of fatty liver.

OBJECTIVETo investigate the etiology of severe hand-foot-mouth disease (HFMD) in children in Henan province.

METHODSA total of 244 HFMD cases admitted to a hospital in Zhengzhou from April to June of 2014 were recruited for research sampling, Real-time RT-PCR, virus isolation, VP1 sequencing and alignment methods were used to test the enterovirus-related etiology. SPSS 17.0 was used in performing statistical analysis.

RESULTSThere were 109 severe and 135 mild cases among all the 244 HFMD cases. The number of enterovirus positive stool samples was 229, with positive rate as 93.85%. EV71, Cox A16 and Cox A10 made up 83.84%, 5.68% and 8.30% of the enterovirus etiologicy, strains, respectively. EV71 infection caused 8 HFMD cases with heart-lung failure and 2 death, Cox A10 infection led to 1 HFMD case with heart-lung failure and death. There were statistically differences seen regarding the enterovirus infection rates between severe and the mild HFMD cases (χ(2)=5.312,P=0.021). Statistically significant difference was seen in the constituent ratio of EV71, Cox A16 and the others by Fisher' s exact test (P=0.048). There was statistically significant difference seen between the cardiorespiratory failure rate and the fatality rate by EV71 and Cox A10 infection (χ(2)=0.051,P=0.821; χ(2)=2.198,P=0.138). Cox A10 strains idenfied in Henan in 2014 belonged to genotype 6. The rates on homology of nucleotide and amino acid among the Cox A10 strains in Henan in 2014 were 94.3%-99.7% and 96.3%-100.0% respectively.

CONCLUSIONSEV71 still remained the most common pathogen that causing severe HFMD in children, with the increasing Cox A10 percentage in the pathogens spectrum of HFMD infection. Cox A10 strains in Henan in 2014 belonged to genotype 6. Genotype 6 Cox A10 had appeared and widely distributed in Henan for long time, but not yet variated or reconstructed. Cox A10 infection could lead to cardio-respiratory failure thus called for the monitoring program on non-EV71 and non-Cox A16 enterovirus, especially Cox A10 to be strenthened.

Objective To explore the impact of IL10-592 (rs1800872) single nucleic acid polymorphism (SNP) on the prognosis of HLA matched unrelated hematopoietic stem cell transplantation (HSCT).Methods The polymorphism of IL10-592 in 104 recipient-donor pairs and 100 healthy volunteers was analyzed with sequence based typing (SBT).Results When the genotype of IL1 0-592 in donors and recipients matched,AA/AA genotype had higher incidence of Ⅲ-Ⅳ aGVHD than AC/AC or CC/CC genotype (47.1％,3.7％,0,P=0.002).When the genotype of IL10-592 in donors and recipients mismatched,recipients with AC genotype or donors with AA genotype,there was significant different incidence of Ⅲ-Ⅳ aGVHD among donors or recipients with different genotype (P=0.046,P=0.041).The recipients with AA genotype had higher incidence of Ⅲ-Ⅳ aGVHD than AC or CC genotype (27.8％ vs 10.2％,11.1％;P=0.072),and higher incidence of intestinal aGVHD (22.2％vs 5.1％,11.1％;P=0.040),lower incidence of 2-year overall survival (OS:48.2％ vs 75.1％,85.7％;P=0.002),lower incidence of 2 year disease free survival (DFS:48.5％ vs 66.3％,76.2％;P=0.045).Patients had higher incidence of Ⅲ-Ⅳ aGVHD with donors of AA genotype than with donors of AC or CC genotype (26.5％ vs 8.9％,0;P=0.024),and higher incidence of intestinal aGVHD (20.4％ vs 4.4％,0;P=0.026).In multivariate analysis,the genotype of IL10-592AA in recipients and donors had increased risk of Ⅲ-Ⅳ aGVHD (OR=3.3,P=0.049;OR=3.9,P=0.043).There were no statistical differences on the incidence of cGVHD and relapse.Conclusion In HLA-10/10 matched unrelated HSCT,the presence of IL10-592 AA genotype in recipients and/or donors is an adverse factor for Ⅲ-ⅣaGVHD,worse OS and 2-year DFS.

Objective To analyze the frequencies of HLA-DQA1 alleles and their clinical values in the donor-recipient HLA-A,-B,-C,-DRB1,-DQB1 (10/10) matched hematopoietic stem cell transplantation (HSCT).Methods This study recruited 127 patients who received allogeneic HSCT and 127 unrelated donors.High-resolution (High Res) DNA typing for HLA-DQA1 alleles were performed on the 254 subjects by using sequence specific oligonucleotide probes (SSOP) and high resolution of sequence specific primer(High Res SSP).Results The DQA1 allele genotypes of 36 pairs of donor-recipient were directly identified by using SSOP.The ambiguous DQA1 allele genotypes of the rest 91 pairs were identified by using High Res SSP.Among the 127 pairs of donor-recipient,5 pairs were HLA-DQA1 alleles mismatched,while the others were all matched.No significant differences in the distribution of HLA-DQA1 alleles were observed between the donors and the recipients.Sixteen HLA-DQA1 alleles were detected in the 127 donors,which were DQA1 * 02 ∶ 01 (19.3％),DQA1* 01 ∶ 02(19.3％),DQA1 * 03 ∶ 02/03 (17.0％),DQA1 *01∶03 (9.8％),DQA1*06∶01(9.1％),DQA1*05∶ 01(7.1％),DQA1*05∶05(5.9％),DQA1*03∶01 (4.7％),DQA1*01 ∶04(2.4％),DQA1*01∶05(2.0％),DQA1*01∶01(1.2％),DQA1*05 ∶ 03(0.8％),DQA1 *05 ∶ 08(0.8％),DQA1*04 ∶ 01(0.4％),DQA1*05 ∶ 06(0.4％) from high to low frequency.Moreover,a new allele was detected in the patients.The haplotypes' frequencies and linkage disequilibrium(LD) analysis of HLA-DQA1 and HLA-DQB1 showed that the most common haplotype was DQA1 *02 ∶ 01-DQB1 *02 ∶ 02(16.1％),followed by DQA1 *03 ∶ 02/03-DQB1 *03 ∶ 03 (11.8％)and DQA1 *01 ∶ 03-DQB1 * 06 ∶ 01 (9.1％).Stronger LD were observed between DQA1 * 02 ∶ 01 and DQB1*02 ∶ 02,DQA1 *03 ∶ 02 and DQB1*03 ∶ 03,DQA1 *01 ∶ 03 and DQB1*06 ∶ 01,HLA-DQA1*06∶01 andDQB1*03 ∶ 01,DQA1*05 ∶ 01 and DQB1*02 ∶ 02(P＜0.001).Conclusion There was strong linkage disequilibrium between HLA-DQA1 and HLA-DQB1 genes.The polymorphism of HLA-DQA1 gene was less than that of HLA-DQB1 gene.No more guidance was provided to donor selection in unrelated donor-recipient HLA matched HSCT by adding HLA-DQA1 genotyping,but it might have clinical application values in HSCT with HLA Ⅱ locus mismatched donor and recipient.

Objective To investigate the predictive value of early prognosis of the 40 Hz auditory steady-state response (40 Hz ASSR) in patients with coma following cardiopulmonary resuscitation (CPR). Methods Thirty patients with coma following CPR admitted in the Neurological Intensive Care Unit (NICU) were examined with the 40 Hz ASSR and shortlatency somatosensory evoked potential (SLSEP), and both were graded. Using transferred out of NICU as the short-term outcome end point, the patients with coma following CPR were divided into a survival group (n =21) and a death group (n =9; including brain death). The correlation between the 40 Hz ASSR and SLSEP grading and prognosis was analyzed. Results The grades of the 40 Hz ASSR (r = 0. 722, P = 0.000) or SLSEP (r = 0. 430, P = 0.018) was significantly correlated with the short-term prognosis. The sensitivity, specificity and accuracy of the 40 Hz ASSR for predicting the short-term prognosis were 77. 8%, 100% and 93.3%, respectively; and those of SLSEP were 88. 9%, 61. 9% and 70. 0%, respectively. Conclusions The 40 Hz ASSR has a certain prognostic value in patients with coma following CPR. The higher the grade of the 40 Hz ASSR is, the greater the likelihood of the recent death.
