Objective To evaluate the efficacy of aerosol inhalation ofXiyanpingversus ribavirin for the treatment of respiratory tract infections in children.MethodsPubMed, Embase, Cochrane database of Systematic Reviews, CNKI, cqvip and wanfangdata were searched. The randomized controlled trials(RCTs) of aerosol inhalation ofXiyanpingversus ribavirin injections for the treatment of respiratory tract infections in children were incuded. The quality of trials was evaluated and data analyses were performed with the Cochrane Collaboration’s software RevMan 5.0.Results A total of 7 trials were included, involving 857 patients(437 treated withXiyanping, 420 treated with ribavirin). Both of the clinical cure rate(50.11%vs. 40.71%) and clinical effective rate(91.08%vs. 75.95%) in theXiyanping group were significantly higher than those in the ribavirin group, withOR(95%CI) 1.49(1.13 to 1.97) and 3.54(1.87 to 6.71), respectively.Conclusions Aerosol inhalation ofXiyanping superior to aerosol inhalation of ribavirin for the treatment of respiratory tract infections in children. Owing to the poor quality and the small sample size of included trials, more larger good quality CRTs are required to confirm this conclusion.

An ultra performance convergence chromatographic ( UPC2 ) method was established for the attribution analysis of the main peaks as well as the quantitative determination of echinacoside andβ-ecdyserone in Bushen Jiannao Grains. The samples were extracted with ethanol and separated on Waters ACQUITY UPC2TM BEH column (100 mm × 3. 00 mm, 1. 7 μm), with a gradient supercritical CO2-0. 05%phosphoric acid-methanol solvent system at 40 ℃. The flow rate was 0. 8 mL/min, the detection wavelength was set at 248 nm and the injection volume was 1 μL. Results showed that all the main peaks in the fingerprint were clearly attributed. The peak named 12 wasβ-ecdyserone with the content of 380μg/g and the peak named 15 was echinacoside with the content of 9. 562 mg/g. The method was simple, eco-friendly, accurate and reliable compared with HPLC and UPLC.

Objective:To explore the value of Neoseq in screening and diagnosis of neonatal fatty acid oxidation disorders (FAOD).Methods:A retrospective case-control study was conducted on 163 500 live births in Changzhou city from April 2015 to April 2021. The following two models were adopted for FAOD screening and diagnosis. (1) Traditional mode: Heel blood samples were obtained from all subjects for initial screening using tandem mass spectrum (TMS), followed by next-generation sequencing (NGS) and other differential diagnostic testings for those with positive results. (2) Neoseq: Neoseq was performed on the true positive, negative and false positive cases according to the traditional mode screening results. The detection rate, additional discovery, reporting period, and other parameters of the two models for FAOD were described and compared.Results:(1) Detection and diagnosis of FAOD: A total of 18 confirmed cases of FAOD were detected through the traditional model, with an incidence of 1/9 083 in Changzhou city. The positive rate was 0.55% (907/163 500) for initial TMS and 0.04% (73/163 500) for the second. The positive predictive value was 2.0%(18/907), with a false positive rate of 98%(889/907) in the initial screening. (2) The results of Neoseq: ①Pathogenic mutations were detected in 16 of the 18 confirmed cases, and the coincidence rate of mutation sites between the two methods was 16/18. The other two confirmed cases were missed diagnosed by Neoseq, including one β-ketothiolase deficiency with only one detected pathogenic mutation and one medium-chain acyl-CoA dehydrogenase deficiency without any detected pathogenic mutation. ②No pathogenic mutations were detected in the 57 false-positive cases by Neoseq. ③Among the 100 negative cases in initial screening, DUOX2 heterozygous mutation, and MTTL1 hemizygous mutation were detected in one case each. ④The median period of results reporting was 43.5 d (28-104 d) for the traditional mode and 12 d (10-15 d) for the Neoseq mode. Conclusions:Neoseq has a high detection rate for FAOD. Combined with TMS screening, Neoseq reduces the false-positive rate of biochemical screening, rapidly identifies genetic causes by shortening the results waiting time and covers diseases that couldn't be detected by traditional biochemical methods.

Objective:To investigate the current status of multidrug-resistant bacteria (MDRO) wound infections in patients with autoimmune bullous diseases (AIBDs), and to analyze their risk factors.Methods:A retrospective study was conducted, and inpatients with AIBDs accompanied by wound infections were collected from Hospital of Dermatology, Chinese Academy of Medical Sciences from January 2020 to December 2022. A descriptive analysis was carried out to analyze the basic characteristics of these patients and pathogenic characteristics of MDRO. Univariate and binary logistic regression models were used to analyze independent risk factors for MDRO infections in patients with AIBDs. Differences between the MDRO infection group and common bacterial infection group were analyzed by using t test, Mann-Whitney U test and chi-square test. Results:Totally, 271 patients with AIBDs accompanied by wound infections were included, including 159 males (58.7%) and 112 females (41.3%), and 142 patients (52.4%) were aged over 60 years. Most patients with AIBDs were diagnosed with pemphigus vulgaris (131 cases, 48.3%), or bullous pemphigoid (99 cases, 36.5%). Bacterial culture was positive in all the patients, and 74 (27.3%) were infected with MDRO; a total of 108 strains of MDRO were detected, with relatively high detection rates of Staphylococcus (82 strains, 75.9%) and Enterobacter (15 strains, 13.9%). Significant differences were observed between the MDRO infection group and the common bacterial infection group in the duration of hospitalization, involved body surface area, proportions of patients self-modificating drug dosage, proportions of patients topically using antibiotic ointments, proportions of patients using immunosuppressants, duration of glucocorticoid use, maximum dose of glucocorticoids and the first albumin level at admission (all P < 0.05), while there were no significant differences in the gender, age, proportions of patients at first hospitalization, types of AIBDs, duration of education, body mass index, disease duration, proportions of smoking patients, proportions of drinking patients, proportions of patients with comorbid chronic diseases, surgical history, prevalence of hypoalbuminemia, prevalence of mucosal involvement, proportions of patients receiving topical glucocorticoids, proportions of patients using biological agents, duration of antibiotic use, and the first total protein level at admission between the two groups (all P > 0.05). Logistic regression analysis showed that the use of topical antibiotic ointments, use of immunosuppressants, maximum dose of glucocorticoids, and self-modification of drug dosage were independent risk factors for MDRO infections (all P < 0.05) . Conclusions:The patients with AIBDs were prone to develop MDRO infections in wounds, and Staphylococcus infections were the most common. The use of topical antibiotic ointments, use of immunosuppressants, high dose of glucocorticoids, and self-modification of drug dosage may increase the risk of infections in patients with AIBDs.

Objective To investigate the influences of maternal gestational diabetes mellitus (GDM) on amino acid levels in neonates.Methods From June 2016 to May 2017,393 pregnancies diagnosed with GDM in Changzhou Maternity and Child Health Care Hospital Affiliated to Nanjing Medical University and 3 924 normal pregnancies were enrolled in this study.Clinical data of the gravidas and their newborns were collected.Heel blood samples were collected at 72 to 96 hours after birth.Tandem mass spectrometry was performed to detect the levels of 11 amino acids including alanine,arginine,citrulline,glycine,leucine/ isoleucine/hydroxyproline,methionine,ornithine,phenylalanine,proline,tyrosine and valine in neonatal heel blood.Differences in amino acid levels between the two groups were compared by t test.Influences of GDM on neonatal amino acid levels were analyzed by multivariate linear regression.Results Compared with the healthy pregnancy group,neonates in the GDM group had higher levels of methionine [(21.01 ±6.30) vs (19.93±6.47) μmol/L,t=3.159,P=0.002] and phenylalanine [(47.19±9.19) vs (45.78±8.58) μ mol/L,t=3.076,P=0.002],but lower levels of alanine [(280.51 ±64.54) vs (290.15±68.40) μ mol/L,t=2.678,P=0.007],proline [(147.64±30.64) vs (152.36±33.57) μ mol/L,t=2.680,P=0.007],tyrosine [(85.21 ±29.50) vs (90.60± 33.32) μ mol/L,t=3.089,P=0.002] and ornithine [(101.22±28.79) vs (105.83±30.10) μmol/L,t=2.906,P=0.004].Multivariate linear regression analysis showed that GDM was responsible for the increase of methionine (β=0.69,95％CI:0.02 to 1.37,P=0.044) and phenylalanine (β=1.60,95％CI:0.69 to 2.51,P=0.001),and the decrease of tyrosine (β=-4.98,95％CI:-8.42 to-1.54,P=0.005) and ornithine (β=-3.16,95％CI:-6.30 to-0.02,P=0.048) in neonates.Conclusions GDM neonates has increased of methionine and phenylalanine levels and decreased tyrosine and omithine levels.

Objective:To investigate the effect of astragaloside Ⅳ on the apoptosis of thyroid cells in Hashimoto's thyroiditis(HT)rats and Ras homolog gene family member A(RhoA)/Rho-associated coiled-coil containing kinase 2(ROCK2)pathway.Methods:The HT rat model was induced by subcutaneous injection of thyroglobulin combined with high iodine drinking water and randomly divided into model group,astragaloside(80 mg/kg)group,Rhosin(RhoA inhibitor,40 mg/kg)group,astragaloside Ⅳ(80 mg/kg)+ Rhosin(40 mg/kg)group(12 rats in each group),another 12 SD rats were selected and drank water normally and injected the same dose of saline subcutaneously as control group.After the drugs were grouped and processed,the serum anti-thyroglobulin antibody(TGAb),anti-thyroid peroxidase antibody(TPOAb)levels and the inflammatory factors IL-6,IL-17,IL-1β contents were measured by ELISA kits;the pathological changes of thyroid tissue in each group were detected by hematoxylin-eosin(HE)staining;the apopto-sis rate of rat thyroid cells in each group were detected by TUNEL staining;the expressions of RhoA/ROCK2 pathway proteins in thy-roid tissues of rats in each group were detected by Western blot.Results:Compared with the control group,the thyroid follicles in the model group had abnormal structure,some atrophy or disappearance,disordered arrangement,surrounding inflammatory cell infiltra-tion,and obvious pathological damage to the thyroid tissue,the serum TGAb,TPOAb,IL-6,IL-17 and IL-1β levels,thyroid cell apoptosis rate,and thyroid tissue RhoA and ROCK2 protein expression levels were significantly increased(P<0.05);compared with model group,the pathological damage of the thyroid tissue of rats in the drug intervention group were reduced,the serum TGAb,TPOAb,IL-6,IL-17 and IL-1β levels,thyroid cell apoptosis rate,and thyroid tissue RhoA and ROCK2 protein expression levels were decreased(P<0.05);compared with astragaloside Ⅳ group and the Rhosin group respectively,the pathological damage of the thyroid tissue of rats in the astragaloside Ⅳ+Rhosin group were further reduced,the serum TGAb,TPOAb,IL-6,IL-17 and IL-1β levels,thyroid cell apoptosis rate,thyroid tissue RhoA and ROCK2 protein expression levels were decreased(P<0.05).Conclusion:Astragaloside Ⅳ may down-regulate the expression of RhoA/ROCK2 pathway to reduce the inflammatory injury of thyroid tissue,inhib-it thyroid cell apoptosis,and improve the symptoms of HT in rats.

Objective:To analyze the costs and effectiveness of five common screening modes and genetic screening for thalassemia in China in order to find the optimal way and provide evidence for the implementation of thalassemia prevention and control projects in Hunan Province.Methods:From June 2020 to April 2021, 12 971 couples from 14 cities and autonomous prefectures in Hunan Province were selected as the study population. The diagnosis of thalassemia was based on the results of genetic testing. Results of routine blood test and hemoglobin electrophoresis were collected and analyzed. The efficacy of five screening modes, at the cut-off value of <80 fl or 82 fl for the mean corpuscular volume (MCV), was analyzed by positive predictive value, negative predictive value, Jorden index and cost-effectiveness ratio. Sensitivity analysis was used to assess the feasibility of genetic screening at different costs after fixing the costs of routine blood and hemoglobin electrophoresis. The five thalassemia screening models are as follows: Mode 1: The woman had a blood routine test first. If the result was positive, the spouse required a blood routine test. If both results were positive, a thalassemia gene test should be offered to the couple. Mode 2: Both husband and wife were screened by blood routine and hemoglobin electrophoresis. If one or both of them were positive, both would be tested for thalassemia gene. Mode 3: The couple received blood routine tests initially. If either was positive, both should receive hemoglobin electrophoresis testing. If either was positive, both parties will conduct thalassemia gene testing. Mode 4: The woman was screened by blood routine and hemoglobin electrophoresis. If any one of them was positive, the woman would be tested for thalassemia gene. If the gene test result was positive, the spouse should receive thalassemia gene. Mode 5: Both spouses conducted a blood routine test. If either was positive, both would conduct hemoglobin electrophoresis test. If both were positive, both spouses should receive thalassemia gene testing. Gene testing mode: The woman would be tested for thalassemia, and her spouse would have thalassemia test too if her result was positive.Results:When using MCV<80 fl as the cut-off for diagnosing thalassemia, the Youden indices of the five prenatal screening modes in Hunan Province were 0.551, 0.639, 0.898, 0.555 and 0.356, while when using MCV<82 fl as the cut-off, the Youden indices were 0.549, 0.629, 0.851, 0.548 and 0.356. When the MCV cut-off value was <80 fl, the missed diagnosis rates of the five screening modes were 44.44%, 0.00, 0.00, 18.52% and 62.96%, and the cost-effectiveness ratios were 21 709, 250 939, 76 870, 138 463 and 92 860 yuan (RMB)/couple, respectively. When the price of genetic testing was lower than 55 yuan (RMB), the cost-effectiveness ratio of genetic screening was lower than that of Mode 3.Conclusions:MCV<80 fl can be considered as the positive criteria in blood routine screening for thalassemia in Hunan Province, and the cost-effectiveness ratio of Mode 3 (the couple received blood routine tests initially. If either was positive, both should receive hemoglobin electrophoresis testing. If either was positive, both parties will conduct thalassemia gene testing) is the best. Genetic screening has certain advantages with the decreasing price.
