Objective To study the clinical features of diagnosis and treatment in children with low-risk myelodysplastic syndrome(MDS) and improve the diagnosis and treatment.Methods The examinations of 17 children with low-risk MDS were analyzed.The blood concentrations of cyclosporine,one of the therapeutic drugs,were monitored and the responses to the treatments were evaluated.Results Exa-mination of full blood count showed that the reductions of 3 cell types,2 cell types and 1 cell type were 11 (64.7%)cases,5(29.4%)cases and 1(5.9%)case,respectively.Reticulocyte count showed an increase in 82.4% of the patients and normal in 3 cases.Fourteen in 17 cases were hyperplastic marrow and 3 cases were hypoplastic marrow.Among all cases,one lineage,2 lineages and 3 lineages dyspoiesis were seen in 8(47.1%),7(41.2%) and 1 (5.9%)cases,respectively.One case showed no dyspoiesis.Cytogenetics examination showed normal in 10(58.8%) cases and abnormal in 7(41.2%) cases.Fifteen (88.2%) cases had normal proportions of CD59 negative cells,while 2 cases had higher proportions.The blood concentrations of cyclosporine that were tested in 9 cases at the end of the third week were in a range of 95.3-316.5 ?g/L.The therapeutic effect of 10 cases were evaluated at the end of the third month after being treated.Eight cases achieved haematological improvement and 2 cases didn′t.The rate of improvement was 80%.Conclusions The patients of low-risk MDS are mostly school-aged children and pancytopenia is the most common sign.The combination of predisone,cyclosporine and stanozolol agents shows good effect to treat low-risk MDS.The absorption of cyclosporine is different individually,so it is significant to adjust the dosage of cyclosporine according to the concentration regularly in clinical practice.

Objective To determine the serum level of pepsinogenⅠ,Ⅱ(PGⅠ,PGⅡ) and PGⅠ/Ⅱin the residents from Zhuanghe county,a high risk area of gastric cancer in North China,and to explore their distribution as well as related factors.Methods Serum PGⅠand PGⅡlevels were detec- ted with ELISA method in 6990 subjects.Gastric diseases were diagnosed by endoscopy and histopatho- logic examination.Serum H.pylori-IgG antibody was determined by ELISA method.Results The me- dian values for PGⅠ,PGⅡ,PGⅠ/Ⅱwere 86.9/?g/L,10.6/zg/L and 8.1 respectively.Serum PGⅠand PGⅡin male(95.2?g/L,12.1?g/L) were significantly higher than those in female(79.7?g/L, 9.4?g/L;P=0.000),PGⅠ/Ⅱratio(7.9) was significantly lower in male (8.3,P=0.000).There were significantly decrease in PGⅠ/Ⅱratio along with age increase.PGⅠ/Ⅱratio decreased signifi- cantly following with progression of gastric mucosa from normal (10.4) to non-atrophic lesions(8.8) and to atrophic lesions (6.6).Serum PGⅠand PGⅡin H. pylori positive subjects (88.7?g/L,11.4?g/L) were significantly higher than those in H.pylori negative subjects (81.4?g/L,8.4?g/L;P= 0.000),PGⅠ/Ⅱratio(7.7) was significantly lower in H.pylori positive subjects (9.6,P=0.000). For patients with atrophic lesions,the area under the PGⅠ/ⅡROC curve was 0.622.The best cut-off point for PGⅠ/Ⅱwas 6.9,with sensitivity of 53.2%,and specificity of 67.5%.Factors linked to PGⅠ/Ⅱwere identified using multinomial logistic regression:male (OR:1.151,95% CI:1.042—1.272, P=0.006),age=61(OR:1.358,95% CI:1.188—1.553,P=0.000),atrophic lesion(OR:2.075,95% CI:1.870—2.302,P=0.000),and H.pylori infection (OR:1.546,95% CI:1.368—1.748,P= 0.000).Conclusions The serum PG levels are significantly skewed from normal distrubition in the residents of Zhuanghe county,and affected by age and gender,as well as associated with gastric diseases and H.pylori in- fection.Compared with PGⅠand PGⅡalone,PGⅠ/Ⅱis more suitable for screening gastric cancer.

In this study, we investigate the bioaccessibility of heavy metals (Cu, Pb, As, Cd and Hg) in wild Artemisia annua and use target hazard quotients (THQ) proposed by US Environmental Protection Agency to assess the health risk under the heavy metal exposure. The results showed that the bioaccessibility of Cu, Pb, As, Cd and Hg in A. annua are 0.77, 0.66, 0.46, 0.68 and 0, respectively, and that the value of THQ for adults and children were 0.030 and 0.025 calculated by risk assessment model. The results indicated that the heavy metals in A. annua were not able to be completely absorbed by human body and that their contents were in a safe range. In this study, by combining the bioavailability of heavy metal and health risk assessment, we assessed the security of heavy metals of wild A. annua, which will provide reference for the standard of heavy metals for medicinal materials.

Objective To investigate the condition of exercise, medicine compliance and the rehabilitation of patients with arteriosclerosis obliterans (ASO) in lower extremity after the surgery, and also to study the influence of self-efficiency and social support to their rehabilitation. Methods The questionnaire survey was performed in 102 patients who had surgical or interventional therapy of arteriosclerosis obliterans in the lower extremity in our hospital, investigated the general information of the patients, their knowledge of postoperative rehabilitation, medicine compliance, exercise condition, general self-efficiency and social support. Results The postoperative time for the patients with arteriosclerosis obliterans was 2 to 22months, the knowledge rate for postoperative rehabilitation was 7.8%-46.1%.The Morisky score for the patients of taking medicine for the treatment of vascular disease was 2.0,and there was only 6 patients(5.9%)with good medicine compliance. There were 22 patients(21.0%) had completed the ambulation training according to the guidelines, and there were 25 patients(24.5%) had completed the Buerger training. The self-efficiency score of the patients was 2.78 ± 0.76, and the gross score of social support was 32.38 ± 7.89. Spearman correlation analysis shows that the Morisky score for the patients of taking medicine for the treatment of vascular disease was in positive correlation with self-efficiency (r=0.289, P=0.003), but in negative correlation with social support (r=–0.286, P=0.006). Conclusions Most of the patients with arteriosclerosis obliterans have poor medicine compliance, and do not do exercise as required by the guidelines. Patients with high self-efficiency demonstrates medicine noncompliance, however the enhancement of social support will help patients improve their medicine compliance.

Objective To analyze the failure ratio and the causes of the inoculation failure of hepatitis B virus(HBV)-vaccine in children and relevant the remedial measures. Methods One thousand three hundred and sixty cases treated in Suzhou Wuzhong people′s hospital during Jan.2007 to Jul.2008 were chosen,of whom 286 children from 1-5 years old to be anti-HBs negative or anti-HBs titre to be 0-10 IU/L were screened,and specific failure reasons for the vaccination were analyzed,also the timely treatment measures were taken.Then 286 children were divided into 5 groups randomly.Apart from one group was set up as blank control,the other 4 groups were arranged to accept different immunization methods with 0,1,2 month schedule,group A simply got revaccinated with HB vaccine(10 ?g) 3 times;group B revaccinated with double dosage of HB vaccine(20 ?g) 3 times;group C besides being revaccinated 3 times,the immune regulatory agent was jointly used;group D revaccinated 3 times with genetically engineered CHO hepatitis B vaccine. Results The ratio of failure of HBV-vaccine was 21.03%,what caused failure of hepatitis B vaccine included immunologic inadequacy 218(76.22%),repeated respiratory infection 192 cases(67.13%),abuse hormone 140 cases(48.95%),zinc deficiency 129 cases(45.10%),anaemia 108 cases(37.76%),passive smoking 80 cases(27.97%),the mother being chronic parenchymatous nephritis or HBV carrier 63 cases(22.03%),premature 54 cases(18.88%),adiposity 38 cases(13.29%),dystrophy 29 cases(10.14%).There were 4 methods of revaccination,the positive rate for group A,B,C,D were 90.00%,96.47%,99.08%,95.83%,respectively.Group C had the highest positive rate,compared with the other 3 groups,which were statistically significant(P a

OBJECTIVEThe study was aimed to investigate the feasibility and clinical significance of quantitative detection of minimal residual disease (MRD) in childhood acute lymphoblastic leukemia (ALL) by real-time quantitative polymerase chain reaction (RQ-PCR).

METHODSClonal IgH gene rearrangements of samples at diagnosis were identified by standard PCR assay with consensus primers. Monoclonal IgH gene rearrangements were analyzed using DNAPLOT software. Upstream primers were designed with the Primer Express software and allele specific oligonucleotide developed complementary to the V-D or D-J junction. Samples at diagnosis were serially diluted to generate the patient specific standard curves. RQ-PCR method was used to quantify the MRD of the follow up samples collected at five time points during chemotherapy. To check the quantity and quality of DNA, the investigators used RQ-PCR analysis for the albumin gene.

RESULTSTotally 16 monoclonal IgH gene rearrangements were identified from 34 patients with B-ALL. The analysis of the 16 monoclonal rearrangements showed that the most frequently used V segment was from V3 family and J segment from J4 and J6. The RQ-PCR sensitivity of 10(-4) to 10(-5) was mostly reached. Non-specific amplification was seen in 6 patients. The number of inserted and deleted nucleotides did not appear to be related to the sensitivity (P > 0.05). The correlation coefficients of all 16 standard curves were excellent (> or = 0.99). The mean slope of the standard curves was -3.4 +/- 0.37 and the mean intercept was 24.3 +/- 2.95. MRD analysis of follow up samples from the 16 patients showed an association between high degree of MRD and relapse. There was no apparent relationship between MRD degree at the end of induction chemotherapy and other high risk factors of ALL (P > 0.05).

CONCLUSIONThe study showed that the above approach with RQ-PCR was applicable to clinical detection of MRD in childhood ALL. Quantitative and dynamic study of MRD was of prognostic importance.

OBJECTIVETo analyze the variation of serum insulin levels in critically ill children and investigate the underlying mechanism and clinical significance to provide the basis for treatment.

METHODTotally 332 critically ill children admitted in pediatric intensive care unit (PICU) of Hunan Children's Hospital from Nov., 2011 to April, 2012 were studied. The high insulin group (n = 332) was defined as insulin levels within 24 h > 11.1 mU/L and was divided into 2 groups: mildly elevated group (n = 194): 11.10 - 33.30 mU/L, increased three times group (n = 138): > 33.3 mU/L. Insulin, C-peptide and blood glucose were measured within 24 hours after admission, on day 3 and 7. Other results of inflammatory markers, lactate, cardiac enzymes, amylase, pancreatic ultrasound, hepatic and renal function as well as indicators related to severity and prognosis were recorded after admission.

RESULTThe peak of insulin level was seen on day 1, then presented a downward trend and reached the normal level on day 7. The peaks of blood glucose and C-peptide level were seen on day 1 then declined, the levels on day 7 were still slightly higher than normal level. The insulin level on admission (41.47 ± 30.85) mU/L were positively correlated with lactic acid (2.29 ± 1.81) mmol/L and procalcitonin level (5.08 ± 6.70) ng/ml (r = 0.370, P = 0.000; r = 0.168, P = 0.002) (P < 0.01). The insulin level on admission in children with 1 organ failure (41.24 ± 22.60) mU/L or 2 or multiple organ failure (48.98 ± 22.17) mU/L was higher than that in children with non-organ failure (34.11 ± 29.84) mU/L (U = 1621.001, P = 0.000;U = 1300.000, P = 0.000) (P < 0.01). The insulin level on admission in death group (52.99 ± 32.34) mU/L was higher than that in survival group (32.85 ± 24.10) mU/L (U = 1585.000, P = 0.000) (P < 0.01). Ten cases in death group were complicated with pancreatic damage and the average insulin level on admission was (65.29 ± 50.53) mU/L.

CONCLUSIONThe high insulin level was correlated with the degree of inflammatory response, ischemia and hypoxia. The high insulin level in critically ill children was relevant to the pancreatic damage, the severity of the disease, organ dysfunction, and evaluation of prognosis.
