ABSTRACT
In 2006, 2014 and 2020, the positive rates of HBsAg in 560, 384 and 402 children aged 1 to 14 years were 4.5%, 2.6% and 2.5%, respectively, with no statistically significant differences (P>0.05). The positive rate of anti-HBs was highest in 2014 (57.8%) and lowest in 2006 (34.1%) (P<0.05). The positive rate of anti-HBc was highest in 2006 (15.7%), and decreased in 2014 (7.8%) and 2020 (5.7%) (P<0.001). The timely rate of the first dose of hepatitis B vaccine for children in Lhasa in 2006, 2014 and 2020 was 7.7% (43/560), 50.3% (193/384) and 94.8% (381/402), respectively. The overall vaccination rates were 15.4% (86/560), 35.2% (135/384) and 96.0% (386/402), respectively, showing a trend of gradual increases (χtrend values were 718.63 and 589.59, both P values<0.001).

The correlations between the clinicopathological features and the long-term outcomes of renal amyloidosis (RA) were analyzed with a view to develop strategies for improving diagnosis and prognosis of RA. We retrospectively reviewed the clinicopathological characteristics of 47 patients diagnosed with RA between 2004 and 2014 at the Wuhan Union Hospital. The data on the renal histology, clinical manifestations, and prognosis of RA patients were retrieved from the hospital records and characteristic patterns were identified. The histological changes in the kidneys were correlated with the clinical manifestations of RA. Additionally, most RA patients in this study had decreased serum levels of κ light chain and increased urine levels of κ and λ light chains as well as presence of M-protein in the urine and serum. Patients with early RA showed no specific pathognomonic symptoms. Bleeding associated with diagnostic renal biopsy was rare. We recommend that the routine work-up of patients aged over 40 years and presenting with non-diabetic nephropathy includes the non-invasive tests for the measurement of serum and urine levels of κ and λ light chains as well as protein electrophoresis tests for the presence of urinary and serum M-protein. Additionally, such patients should undergo renal biopsy screening with Cong-red staining to ensure early diagnosis of RA and improve their survival, since the risk of hemorrhage related to renal biopsy screening is low at early stages of RA.

The efficacy and safety of tacrolimus (TAC) and cyclophosphamide (CTX) in the treatment of idiopathic membranous nephropathy (IMN) were compared in Chinese adult patients using a meta- analysis of the available literatures. Randomized controlled clinical trials (RCTs) of the treatment of primary IMN with TAC or CTX combined with corticosteroids in the English databases PubMed, Embase and Cochrane, as well as Chinese databases, were searched. Qualified studies were subjected to quality assessment and meta-analysis. A total of 8 RCTs, including 359 Chinese patients, were included in the meta-analysis. The complete remission rate and overall remission rate in the TAC treatment group after 6 months of treatment were higher than those in the CTX treatment group. No significant difference in remission rate was found after 12 months of treatment. There was no significant difference in the adverse reaction between the two groups at the 6th or 12th months. TAC-based treatment was associated with a faster response than CTX at the 6th month, but there was no significant difference between the two groups at 12th month in Chinese adults. Further study is needed to evaluate the long-term efficacy and safety of this treatment regimen.

Objective To study the telomerase expression in peripheral blood mononuclear cells(PBMCs) in children with acute Kawasaki disease(KD) and its clinical significance.Methods The PBMCs of 64 children with acute KD [25 cases of them with coronary artery lesions(CAL),while the rest without] from 2 months to 6 years old admitted into Jiangxi Children's Hospital from Mar.2005 to Dec.2008 and those of 52 sex-age-matched healthy children (healthy control group) from 5 months to 7 years old were all assayed by Roche telomerase polymerase chain reaction enzymelinked immunosorbent assay(PCR ELISA).WBC,ESR and CRP were also detected.SPSS 11.0 software was used to analyze the data.Results The telomerase expression frequency of PBMCs in children with KD was 32.8%(21/64 cases),while that in healthy control group was only 15.4%(8/52 cases),the difference between the 2 groups was significant (?2= 4.65,P0.05).There were no significant difference of WBC,ESR and CRP between the telomerase of PBMCs positive group and negative group.Conclusions The higher frequency of telomerase expression in peripheral blood lymphocytes might be related to the development and progression of KD.
ABSTRACT
Objective To explore the clinical effects of aminophylline on bronchiolitis in children.Methods One hundred and twen-ty-eight children with bronchiolitis in our hospital were randomly divided into the experiment and treated control group,in the meantime,and divided into the severe and mild group according to their condition.The children in control group were treated with traditional methods,in experiment group were treated with aminophylline(2 mg/kg,every day one time),as well as used traditional methods.All patients in 2 groups were checked by volume (VT), inhale time and exhale time ratio (Ti/tE),time to peak expiratory flow and expiratory time ratio(tPTEF/Te),time to peak expiratory flow to total expiratory time and volume ratio(vPTEF/vE) respectively. Meanwhile pulmonary function,alkyla-denine glycosylase in trachea secretion,IL-8,cytotaxonomy in trachea secretion on time,after the third day and the 7th day.Their curative effects were evaluated.All parameters were analyzed by statistical methods.Results Cytotaxonomy of the patients in the experiment were more improved than that of control group(P
ABSTRACT
Objective To explore the significance of nuclear factor-?B(NF-?B)activation in peripheral blood mononuclear cells(PBMC)during acute Kawasaki disease(KD).Methods Peripheral blood was collected from children with acute KD(n=30)and healthy age-matched children(n=20).PBMC were cultured in vitro and divided into 3 groups:naturally cultured blank control group,protein kinase C(PKC)activator stimulated phorbol 12-myristate 13-acetate(PMA)group and PMA plus NF-?B inhibitor treated PMA plus pyrrolidine dithiocarbamate(PDTC)group.Percentages of NF-?B activation were detected by immunohistochemistry.Results Under natural culturing,the percentage of cells with activated NF-?B was significantly higher in acute KD blank control group than that in healthy blank control group.The percentage of cells with activated NF-?B was significantly higher in acute KD PMA group than that in acute KD blank group and that in normal control PMA group,respectively(Pa0.05).Conclusions NF-?B activation in PBMC during acute KD is markedly increased,which suggests that NF-?B activation plays an important role in the formation of vasulitis and CAL in this disease.NF-?B activation in PBMCs in children with KD is regulated by the PKC signaling pathway and PDTC obviously inhibits the activation of NF-?B.J Appl Clin Pediatr,2009,24(1):35-37
