Objectives To search for the relationship between HP and lesions of gastric mucosa of children.Methods Four hundred and fifty-eight bioptic specimens-from eastrie mueosa in children were strained with hematoxylin-eosin(HE)and Warthin-Starry for light microscopic study.Results HP was detected in 152 specimens. HP deteetable rate-in specimens with normal mucosa was 1. 1%, in compari-on with 42.3% in those with chronic superficial gastritis and 14. 3% in those with chronic atrophic gastrins .Specimens with chronic active gastritls, mostry manitesting local active lesions,had HP detectable rate of as high as 80.2%、69. 7% of the specimene with HP were found to have obvious lymph follicles reaction within lamina propria in their gastric mucosa.Conclusions There is a close relationship between HP infection and Pediatric chronic gastritis(especially chronic active gastritis). Histopathologically, HP-associated gastritis is characterized by chronic and local active inflamations, and tbe formation of lymph follicles within lamina propria.

AIM: To study the optimal condition and parameters for the enrichment process of paeoniflorin in Kunyining Granules (Radix Paeoniae Rubra, etc.) with macroreticular resin. METHODS: With the enrichment degree of paeoniflorin in Kunyining Granules as an index, the optimal conditions of the enrichment process were investigated. RESULTS: The optimal condition showed that the aqueous extract was taken into the macroporous resin column, and kept for 30 min, then the resin was washed by water to get rid of impurity and then we used six times as much 50% ethanol as aqueous extract to elute paeoniflorin. CONCLUSION: The process is feasible to enrich paeoniflorin from Kunyining Granules.

Objective To study the multi-detector spiral CT (MDCT) features of pancreatic tuberculosis to improve the awareness and correct diagnosis. Methods Imaging features of MDCT were retrospectively reviewed on 9 cases with pancreatic tuberculosis that were diagnosed from 2003 to 2009, among them two patients underwent MDCT angiography, the features were compared with those of operative and pathological findings. Results One case of pancreatic cancer, 2 cases of cystadenocarcinoma and 1 case of pseudocyst, 2 cases of pancreatic cancer with retroperitoneal lymph node metastasis, 2 cases of lymphoma were diagnosed by MDCT, and all the lesions were diagnosed as pancreatic tuberculosis pathologically, and the misdiagnosis rate was 100%. Pancreatic tuberculosis often presented as pancreatic head mass, sometimes pancreatic body and tail were involved. MDCT showed isopycnic or low density solid-cyst mass, occasionally calcification was present, with slightly or moderate ring-like enhancement after contrast injection. There was no enlargement of the pancreatic duct. The retroperitoneal and adjacent lymph nodes were always enlarged with ring-like enhancement. Sometimes there was evidence of tuberculosis of other abdominal organs. Conclusions Ring-like enhanced lesions with ring-like enhanced lymph nodes without enlargement of pancreatic duct are characteristic MDCT features of pancreatic tuberculosis.

Objective Through the application of recombinant human Ⅱ tumor necrosis factor-Fc function protein (rhTNFR:Fc) in the treatment of juvenile idiopathic arthritis (JIA) with randomized control study,clinical characteristic and clinical effect were summarized.Methods According to the randomized controlled principle,124 patients with JIA were divided into control group and treatment group.The basic treatment in two groups were one antirheumatic slow-acting drug,nonsteroidal drug,adrenal cortical hormone.There were no significant differences between clinical type and basic treatment in two groups (P ＞ 0.05).Sixty-two patients of JIA treated with rhTNFR:Fc by subcutaneous injection.The doses was 0.8mg /kg per week.There were 17 cases of oligoarthritis,15 cases of polyarthritis,30 cases of systemic arthritis in the treatment group and control group respectively.The basic antirheumatic drugs,nonsteroidal anti-inflamatory drugs ( NSAIDs),adrenal cortex hormone were allowed to continued.Clinical evaluation index included ACR Pedi 30,ACR Pedi 50 and ACR Pedi 70.The adverse drug reactions were recorded.Results The remission rate of ACR Pedi 30,50,70 in 2 weeks,one month,three monthes and six monthes were different in types of JIA patients in the treatment group ( P ＜ 0.05 ).The remission rate of systemic arthritis was lower than the other two groups of arthritis ( P ＜ 0.05 ).Only 44％ ACR Pedi 50 remission was achieved after three monthes medication in systemic arthritis and 41.7％ ACR Pedi 50,29.2％ ACR Pedi 70 were achieved after six monthes.The remission rate in the types of oligoarthritis and polyarthritis at different time points (2 weeks,one month,three monthes,six monthes) of ACR Pedi 30,50,70 were similar.After six monthes,more than 80％ reached ACR Pedi 50 remission,more than half of patients reached ACR Pedi 70 remission.Three cases of macrophage activation syndrome in systemic arthritis group was effective treated with rhTNFR:Fc.In the treatment group,2 cases of systemic arthritis appeared ache and discomfort after one week treatment,3 cases appeared repeated mild upper respiratory tract infection and diarrhea during treatment,including one varicella infection.The incidence of adverse reactions in the treatment group of systemic arthritis were 16.7％,Other 2 types of patients did not show adverse reaction during rhTNFR:Fc treatment.Conclusion rhTNFR:Fc has good effect on oligoarthritis and polyarthritis of JIA.The adverse reactions of six monthes were rare.The cases of systemic arthritis could reach some clinical remission,but need to guard against infection and the occurrence of adverse reactions.To whom did not respond to conventional therapy in systemic arthritis or systemic arthritis combined with macrophage activation syndrome,it could be considered with rhTNFR:Fc.

Objective:To investigate the therapeutic efficacy of Golimumab in the treatment of children with refractory juvenile dermatomyositis(JDM).Methods:The clinical data of a child diagnosed with JDM in the Department of Allergy, Immunology and Rheumatology of Guangzhou Women and Children′s Medical Center in February 2019 were collected.The treatment effect was studied and literature review was conducted.Results:The patient was a 7-year-old boy with subacute onset of the disease.The illness protracted, and main manifestations included skin rashes, limb weakness, and swallowing dysfunction.Physical examination showed heliotropic rashes, Gottron papules, positive Gower, proximal limb muscle strength grade Ⅲ-Ⅳ, distal limb muscle strength grade Ⅳ, and a choking cough when swallowing fluid food.Laboratory tests revealed alanine aminotransferase (ALT) of 36 U/L, aspartate aminotransferase (AST) of 115 U/L, alkaline phosphatase of 69 U/L, lactate dehydrogenase of 941 U/L, creatine kinase of 974 U/L, hypersensitive C-reactive protein of 26 mg/L and an erythrocyte sedimentation rate (ESR) of 52 mm/1 h. Antinuclear antibody spectra were negative.Electromyography suggested myogenic damage.Thigh magnetic resonance imaging indicated diffuse abnormal signal shadows in the subcutaneous fat, muscles and muscle spaces of both hips, thighs and knee joints.The child was diagnosed with JDM, and given standardized treatment of Methylprednisolone, intravenous immunoglobulin, Methotrexate and Hydroxychloroquine sulfate.However, after the treatment, the facial rashes were still red, proximal limb muscle strength and swallowing dysfunction did not improve, the choking cough symptom still existed, and a Cushing face appeared.Recheck results showed ALT of 24 U/L, AST of 32 U/L, alkaline phosphatase of 56 U/L, lactate dehydrogenase of 216 U/L, creatine kinase of 527 U/L, hypersensitive C-reactive protein of 8 mg/L and an ESR of 15 mm/1 h. Refractory JDM was considered.After negotiating with the patient′s family members, they agreed to treat the patient with Golimumab 50 mg by subcutaneous injection once a month.Then tapered prednisone gradually, stopped Hydroxychloroquine sulfate tablets and continued to give the patient oral Methotrexate.After two doses of Golimumab 50 mg, proximal limb muscle strength and swallowing function improved markedly.After the third subcutaneous injection of Golimumab, proximal limb muscle strength improved to grade Ⅳ-Ⅴ, and he was able to go up and down stairs, squat and stand up after squatting.Besides, dysphagia and the choking cough disappeared, and skin rashes improved.Recheck results suggested a normal ESR and creatine kinase levels.Magnetic resonance imaging of thighs indicated no muscle inflammation.Conclusions:Golimumab works well in the treatment of refractory JDM and can effectively improve muscle strength.Therefore, it can be used as a treatment option for refractory JDM.
