Objective To explore the influence of helicobacter pylori(Hp) on gastric motor function in children with chronic gastrictis.Methods Forty-seven children with chronic gastrictis were classified into Hp positive and negative groups according to Hp and histology exa-mination.Each child underwent gastric emptying test of solid by using nuclide method and electrogastrogram(EGG) examination.These cases with Hp-positive acceptted these triple eradication therapy[clarithromycin 15 mg/(kg?d),amoxicillin 50 mg/(kg?d),omeprazole 0.8 mg/(kg?d)]for 2 weeks,and underwent EGG examination again after eradicating Hp.Results The half emptying time(GET_1/2)in Hp-positive gastric group were significantly longer than those in Hp-negative group(t=6.403 P

Vibrio parahaemolyticus has been considered as one of the most important foodborne bacterial pathogens.The loop-mediated isothermal amplification(LAMP) that amplifies DNA with high specificity and rapidity under an isothermal condition was applied for rapid detection of this pathogen for the first time.A set of four primers,two outer and two inner primers,was designed specifically to recognize the thermolabile hemolysin gene(tlh) of V.parahaemolyticus.The LAMP reaction mix was optimized.The most optimal reaction temperature and time of the LAMP assay for the tlh gene were 60℃ and 60min,respectively.Genomic DNAs from 28 bacterial strains including 14 V.parahaemolyticus strains were amplified using LAMP,and no amplicon was observed in other bacterial strains.The detection limit of this LAMP assay was around 90 fg of V.parahaemolyticus genomic DNA and 24 colonies forming units for pure cultures.In addition,this method was applied to detect artificially contaminated food samples,and the detection limit was 89 cfu/g for non-cultured artificially contaminated food samples.These results suggested that detection of V.parahaemolyticus by LAMP is an effective and low-cost procedure with high specificity and sensitivity that requires no specialized equipment.This assay is expected to become a valuable tool for rapid detection and identification of V.parahaemolyticus.

Objective To explore the effect of treatment of children's stress hyperglycemia with glucose-insulin-potassium.Methods Thirty children with stress hyperglycemia were randomly divided into two groups,15 cases in each group.Patients in the treated group were admi-nistered with glucose-insulin-potassium,whereas those in the control group,glucose were transfused at the speed

Objective To observe the immunologic effect of lactoferrin on repeated respiratory infection(IRRI) in children.Methods Ninety-eight cases of IRRI were divided into two groups randomly.The control group (48 cases)were treated with routine therapy.The treatment group(50 cases) were treated with lactoferrin based on routine therapy for 2-3 months.T cell subgroup,immunoglobulin and complements were determined before and after treatment.Results Total effective rates in treatment group and control group were 86% and 22.9% respectively.The therapeutic efficacy in treatment group was significantly higher than that in control group(P

Objective To explore the correlation between time-intensity curve (TIC) parameters of CEUS and microvessel density (MVD) of inverted papilloma of bladder (IPB) and bladder urothelial carcinoma (BUC).Methods Clinical and CEUS characteristics of 30 patients with IPB and 50 patients with BUC confirmed by pathology were retrospectively analyzed.CEUS TIC parameters included rise time (RT),mean transit time (MTT),peak intensiy (PI),time from peak to one half (TPH),wash in slope (WIS),time to peak (TP),semi-descending slope (DS) were acquired by QLab software and statistical analysis was carried out.The MVD of the resectioned tissue specimens were quantified via immunohistochemistry for CD34 and the correlation with CEUS TIC parameters was investigated.Results In CEUS quantitative parameters,PI,TPH,TP and DS had statistical significance in IPB and BUC (all P＜＜0.05).MVD of BUC was obviously higher than that of IPB (P＜0.05);TPH and DS both correlated with MVD (rs =0.74,-0.81,both P＜0.05).Conclu sion CEUS characteristics has certain clinical value in identification of IPB and BUC.TIC parameters of CEUS can reflect the MVD of IPB and BUC.

AIM: To compare the effectiveness of botulinus toxin of type A and complete resection of the periorbital muscle on idiopathic blepharospasm.
● METHODS: Patients with idiopathic blepharospasm and having undergone either of two procedures from Dec. 2010 to Jun. 2015 were selected ( 60 patients ) . Among them, group A (30 patients, 60 eyes) underwent botulinus toxin of type A, group B (30 patients, 60 eyes) underwent complete resection of the periorbital muscle.
●RESULTS: ln group A, the patients with complete response, obvious response, partial response, and no response were 36(60. 0%), 20(33. 3%), 2(3. 3%) and 2 (3. 3%) cases respectively. ln group B, the patients with complete response, obvious response, partial response, and no response were 16(26. 7%), 24(40. 0), 12(20. 0%) and 8 ( 13. 3%) cases respectively. The difference was statistically significant ( Z = - 2. 968, P = 0. 003 ). The relapse rate of group A and group B were 93. 3% and 20. 0% after 6mo, the difference was statistically significant (χ2=32. 851, P<0. 001).
●CONCLUSION: The botulinus toxin injection of type A is effective for idiopathic blepharospasm. But recurrence rate is high after 6mo. Complete resection of the periorbital muscle have long-term efficacy for idiopathic blepharospasm. It′s a supplementary therapy after idiopathic blepharospasm recurrence.

Objective:To investigate the clinical features, the key point of diagnosis and treatment methods of X-linked hyper-IgM syndrome (XHIGM).Methods:The clinical characteristics and laboratory data of a patient aged 23 years who was diagnosed as XHIGM complicated with T-cell large granular lymphocytic leukemia (TLGLL) in Institute of Hematology & Blood Diseases Hospital in March 2020 were analyzed retrospectively, and the literatures were reviewed.Results:This male patient presented with recurrent infection when he was 17 years old, and was found neutropenia, anemia accompanied by obvious splenomegaly, lower level of IgG and IgA after the visit. The level of IgM was lower than the normal level and the typical XHIGM was manifested with the normal or increased level of IgM, however CD40L homozygous mutation (chromosome: chrX; location: 135730438; variation of amino acid: NM_000074:exon1:c.31C>T:p.R11X; nonsense mutation) was confirmed by next generation sequencing. CD40L heterozygous mutation was detected in his mother, but it was not in his father. The patient was diagnosed as XHIGM. Anemia and neutropenia were alleviated after splenectomy in the patient, who was diagnosed as T-cell large granular lymphocyte elevation and clonal proliferation by flow cytometry, TCR gene rearrangement positive and bone marrow histopathological immunohistochemistry results because of the increasing leukocyte. The patient was eventually diagnosed as XHIGM complicated with T-LGLL.Conclusions:A small number of patients with XHIGM may develop symptoms in adulthood and may present with atypical clinical features of significant reduction in IgG, IgA, and IgM. The confirmed diagnosis of XHIGM is established by identification of CD40L gene mutation. XHIGM gene screening is required in male patients with recurrent infection, IgG level lower than normal and neutropenia. A few XHIGM patients are complicated with T-LGLL.
