Objective To study the relationship between systemic lupus erythematosus (SLE) and human cytomegalovirus (HCMV) infection.Methods HCMV was isolated from the peripheral blood leucocytes (PBL) of 63 patients with SLE.Indirect immunofluorescence (IIF) was performed to investigate HCMV pp65 antigen and polymerase chain reaction (PCH) was performed to investigate the expression of HCMV UL54 DNA in cell cultures.The clinical and Iaboratory parameters were also assessed.Results The rate of HCMV infection in SLF patients was higher than that in the healthy controls and SLE patients.It was higher in the active phase than in the inactive phase.The total amount of urine protein in 24 houm collection,ESR,SLEDA1,preyalence of arthritis and some autoantibodies were considerably higher in patients with positive HCMV infection than those with negative HCMV infection.Conclusion The HCMV infection rate in SLE patients is higher than healthy controls.HC:MV infection may contribute to the disease flare in some SLE pahents.

Objective To discuss the methods of selecting different shapes occluder and to evaluate the feasibility,safety and efficacy of them in transcatheter closures of congenital ventricular septal defect (VSD) in children.Methods Transcatheter closures were performed in 226 children with congenital VSD,age ranging from 2 to 14 years(mean 5.62 years) under the guidance of transthoracic echocardiography(TTE) and fluoroscopy.There were 14 patients with intracristal VSD,209 patients with perimembranous VSD and 3 patients with muscular VSD.Left ventriculography and transthoracic echocardiography were performed repeatedly after the procedure to assess the effect of occlusion.The echocardiography and electrocardiography were scheduled before discharge,1,6 and 12 months for the follow-up.Results The occluders were deployed successfully in 211 patients.The successful rate was 93.4%.Thin waist shape occluders,were deployed in 7 patients;equal side shape occluders,were deployed in 191 patients;eccentric shape occluders were deployed in 12 patients,and muscular defect occluders were deployed in 1 patient.There were no complications encountered during or after closure.Conclusions It is very important in transcatheter closure of congenital in children to select different shape occluder according to pathologic characteristics.In general,equal side shape occluder is suita-ble for a large number of defect and it is easy for deployment.In some conditions,the other shape occluder may be necessary.

Objective To detect the type of gene mutation of thalassemia in Kunming city.Methods Sixty-three cases highly suspec-tive of thalassemia were determined with the methods of ploymerase chain reaction(PCR) and reverse dot blot(RDB) for the type of gene mutation.Results According to gene analysis,35 cases were final diagnosed from 63 cases suspective of thalassemia.Among the total,4 cases were gene deficiency ?-thalassemia,and 30 cases were gene deficiency ?-thalassemia,and there was 1 case both ?-thalassemia and ?-thalassemia.There were 9 types of gene mutation with 15 gene combinations in 35 samples.The main type of ?-thalassemia was--SEA/??,there were 6 types with 11 gene combinations from the types of genes of ?-thalassemia,the highest incidence of gene mutation was 17 site,including 17 site homozygote,heterozygote and double heterozygote.Conclusions The thalassemia invasion of Yunnan has its characters,and it is valuable to launch further research.In the same patient,there are ?-thalassemia and ?-thalassemia,it signifies that those 2 types should be diagnosed in the same time,to prevent missed diagnosis.

Objective To test the level of cell factor interleukin (IL)-21,CXCL13 in the plasma of patients with rheumatoid arthritis (RA),and to analyze the relationship between Follicular helper T cells(Tfh)and clinic features and discuss the possible immunological pathogenesis of RA.Methods The Tfh cells were obtained from patients and healthy controls (NC) and detected by Flow cytometery.While the levels of IL-21,CXCL13 in patients and NC were measured by ELISA tests.Those analysis were performed by student's t-test,one-way ANOVA,SNK-q test,Chi-square test,Spearman's correlation and multiple linear regression.Results The expression of CD4+CXCR5+ICOS+ cells (Tfh) in PBMCs of RA was significantly higher than normal controls (3.0±1.2 vs 1.1±0.4,P＜0.01).Meanwhile,the three RA groups of patients were divided to low,moderate and high disease activity groups,and the results showed that the expression of Tfh were increased accordingly (1.8±0.7,2.5±0.6,4.0±1.2).The expression of Tfh in the three groups were all significantly higher than that of controls (P＜0.01).There was a positive correlation between Tfh and DAS28,ESR,CRP,TJC,and bone erosion,RF and anti-CCP respectively.The expression of Tfh in those patients who had bone destruction was higher than those with no or mild bone destructions (2.7±1.1vs 3.4±1.3).The expression of Tfh in patients with un-treated RA patients,when compared to those RA patients who were treated appropriately and those who were not treated appropriately,was decreased significantly.The expression of Tfh in appropriately treated RA patients was lower than that without appropriately treatment.The level of IL-21,CXCL13 was decreased in patients with RA in the order of high,moderate,low disease activity and NC.Conclusion The expression of Tfh and the levels of IL-21,CXCL13 are increased significantly,and are closely related to disease activity and bone ersions.The expression of Tfh is decreased after relevant treatment.These results indicate that the abnormality of Tfh may play an important role in the pathogenesis of RA.

In this article, the Chinese Traditional Medicine and Materia Medica Subject Headings, Standards of the People's Republic of China - Classification and Codes of Diseases and Zheng of Traditional Chinese Medicine and the Chinese Terms in Traditional Chinese Medicine and Pharmacy were compared. Three standards were compared from the terminology quantity, content and classification. Each standard has its special feature. The compatibility and consistency are not strong in these standards. More authoritative traditional Chinese medicine terminology standards need to be established for the application in the clinical practice and scientific research.

Objective:To understand the clinical characteristics and prognosis of Langerhans cell histiocytosis (LCH) with skin-limited lesion.Methods:A retrospective analysis was performed on clinical characteristics and prognosis of 16 skin-limited LCH patients, out of 578 LCH patients who were hospitalized in Beijing Children′s Hospital during December 2013 to June 2018.Results:A total of 16 skin-limited LCH cases, accounted for 2.7% of all 578 cases, were included.Among which, sex ratio (male vs.female) was 1.28∶1.00.Median ages of skin eruption occurrence and of diagnosis of the disease were 3.5 months (3 days to 2 years and 5 months) and 6 months (2 months 14 days to 2 years and 8 months) in this group.Among the 16 cases, seborrheic dermatitis-like lesions(11 cases, 68.7%) was the most common, and the trunk was most frequently involved[75.0% (12 cases)]. Serine/threonine protein kinase gene V600E [ BRAF (p.V600E)] mutation was detected in pathological specimens from 10 skin-limi-ted cases, with 9 cases being positive.Plasma samples from 5 positive cases were further detected for BRAF (p.V600E) mutation, and 4 positive results were gained.Of all 16 patients, 11 cases (68.7%) were treated.Remission were achieved in 3-6 months from treatment start in patients treated whether according to the Histiocyte Society′s LCH-2009 protocol for 25 weeks(6 cases, 37.5%), or with topical mometasonefuroate for 3 months (3 cases, 18.8%). Two patients(12.5%) with solitary cutaneous lesions underwent excision biopsy (one face and one prepuce) and were considered to be in remission immediately after surgery.None of these patients suffered from the recurrence of the disease.The remaining 5 patients (31.3%) with skin-limited LCH were just evaluated regularly, and achieved remission in 3-6 months of commencing observation.Among these untreated patients, 1 with consistently positive BRAF (p.V600E) mutation in plasma had bone involvement in the 24 th month of assessment, and was then treated based on the Histiocyte Society′s LCH-2009 Protocol.No clinical or imageological evidence supporting disease progression was found on this patient.Median follow-up period was 32.8 months (2.9-63.9 months). Except one patient, none of the rest cases had active disease till follow-up ended.Two-year event free survival(EFS) of this research was (92.3± 7.4)%.There was no significant difference between EFS of treated group and that of observation group( χ2=1.250, P=0.264). Conclusions:Skin-limited LCH often occurs in infants and newborns, with strong heterogeneity in clinical manifestations, laboratory indicators, and pathogenesis.Seborrheic dermatitis-like lesions were the most common cutaneous type.The prognosis of the patients is excellent despite progressing into multisystem involvement can be seen in a few patients.
