Objective To summarize the epidemiology and evaluate possible age-related differences in the presenting clinical features in three year-old children with Mycoplasma pneumoniae pneumonia(MPP)during 2009 to 2014.Methods The medical records of 17855 children with community-acquired pneumonia enrolled by Children′s Hospital of Soochow University during 2009 to 2014.Totally 1145 younger than three year-old children with MPP were enrolled,and they were classified into three groups of 1 month to 1 year-old group (n=512),1 to 2 year-old group (n=393) and 2 to 3 year-old group (n=240).The epidemiology and possible age-related differences in the presenting clinical features,main laboratory and imaging results in three year-old children with MPP were summarized.Results (1) The highest infection rate of different reasons in Suzhou was in autumn(10.46%),and the lowest was in spring(6.95%),The highest infection rate of different ages was 2 to 3 year-old group(11.61%),and the difference was statistically significant (P<0.05).(2) Compared with 1 month to 1 year-old group(n=512,4.31%) and 1 to 2 year-old group (n=39,10.09%),2 to 3 year-old group (n=240,11.61%) had higher infection rate,more patients with fever(53.9% vs. 77.1% vs. 85.4%) and high fever(16.8% vs. 30.5% vs. 41.4%),longer time to normalization of temperature(3d vs. 5d vs. 6d),but less patients with wheezing(61.3% vs. 52.4% vs. 42.9%) and dyspnea(7.6% vs. 4.6% vs. 3.8%).(3) The differences were statistically significant in the percentage of neutrophils,lymphocytes,CRP and platelet count between different ages(P<0.001).(4) The incidences of large area of lesions in chest X-ray examination among different ages had significant differences(P<0.001).Conclusions MP is one of the important pathogens of respiratory tract infection in younger than 3 year-old children.It can occur in every season,and the highest infection rate of MP is in autumn and spring.In younger than 3 year-old,older patients are more vulnerable to infection of MP,the number of fever and high fever are more,fever duration is longer,but younger patients are more vulnerable to virus infection and prone to dyspnea.Chest X-ray examination shows small patchy shadow in most cases,the younger children are more easily to have large area of lesions and pleural effusion.

ObjectiveTo observe the efficacy of a Levofloxacin-containing 10-day sequential therapy for Helicobacter pylori eradication.Methods Totally 86 Helicobacter pylori-infected patients with chronic gastritis or peptic ulcer diagnosed by gastroscopy were randomized into two groups: the trial group and the control group (n =43 in each group).The trial group was treated with Esomeprazole 20 mg bid plus Amoxicillin 1000 mg bid at the first 5 days,and followed by Esomeprazole 20 mg bid,Levofloxacin 500 mg qd and Furazolidone 100 mg bid,at the last 5 days;The control group was treated with standard triple regimen: Esomeprazole 20 mg,Amoxicillin 1000 mg and Clarithromycin 500 mg,all bid for 7 days.The eradication rates of Helicobacter pylori in the two groups were compared after completion of treatment.ResultsAfter treatment,the eradication rates of Helicobacter pylori were significantly different between the trial and control group(93.0％ vs 74.4％,P ＜0.05)Conclusion The 10-day sequential therapy with.Levofloxacin-containing regime can achieve a higher eradication rate of Helicobacter pylori infection.

Objective To explore the relationship of thyrotropin receptor antibody (TRAb) and soluble intercellular adhesion molecule-1 ( sICAM-1 ) in patients with thyroid-associated ophthalmopathy ( TAO), and the role played by TRAb and sICAM-1 in the pathogenesis of TAO. Method Twenty-three TAO patients were assigned to groups according to the clinical activity score and EUGOGO. All patients were treated with intravenous methylprednisolone pulse. The levels of serum TRAb and sICAM-1 were evaluated by a competitive radioimmunoassay and enzyme-linked immunosorbent assay respectively before treatment and by the end of each methylprednisolone pulse. Results The differernce in serum TRAb levels was associated with activity scores of TAO (P=0. 020). The change in serum sICAM-1 was associated with durations of TAO ( P = 0.015). During methylprednisolone treatment in active TAO patients, the levels of TRAb kept on decreasing gradually and markedly declined after the third methylprednisolone pulse in active TAO patients (P＜0.05). The trends of changes in serum TRAb and sICAM-1 levels were both different in active and inactive TAO patients by tendency analysis. Conclusion TRAb level was related to the activity of TAO and might serve as a significant predictor of response to methylprednisolone therapy. The negative correlation between sICAM-1 levels and duration of TAO corroborates the role played by ICAM-1 during the early stage of TAO. Higher sICAM-1 levels are not expected to be specific to TAO and may not predict a response to methylprednisolone therapy.

Objective To investigate changes in lengths of the wrist ligaments during wrist radioulnar deviation. Methods Six volunteers were included in the study. CT scans was used to detect the changes under different positions of the wrist in the volunteers. The wrists were scanned from the position of radial deviation of 20° to the one of ulnar deviation of 40° at an interval of 20°. The 3-dimensional carpal and distal radioulnar joint structures were reconstructed with customized software and chauges in length of the palmar and dorsal wrist ligaments in radioulnar deviation were computed. Results From wrist radial deviation to neutral position, the lengths of the radioscaphocapitate ligament, the long radiolunate ligament and the dorsal intercarpal ligament increased significantly (P ＜ 0.05), they increased (2.4±0.3) mm, (2.3±0.8) mm,(1.2±0.6) mm, (1.2±1.2)mm and (2.6±1.0) mm respectively. While from wrist ulnar deviation to neutral position, ulnocapitate ligament and the dorsal radiocarpal ligament increased significantly (P ＜ 0.05), they increased (0.8 ±0.6) nm and (1.0±0.5) mm respectively. Conclusion At wrist radial deviation, the radioscaphocapitate, long radiolunate and dorsal intercarpal ligaments are slack. At wrist ulnar deviation, the ulnocapitate ligament and the dorsal radiocarpal ligament are slack. These positions may be favorable to healing of these ligaments.

Objective To investigate transmission routes of healthcare-associated infection(HAI)caused by methi-cillin-resistant Staphylococcus aureus (MRSA),and make effective measures for preventing and controlling the oc-currence and epidemic of HAI caused by multidrug-resistance bacteria.Methods From February 24 to March 29, 2012,12 MRSA-infected patients were performed epidemiological study,these patients underwent bronchoscopy be-cause of tracheal stenosis,strains were identified by amplifying the sequences of 16S rRNA ,femA and mecA with real-time quantitative polymerase chain reaction (PCR),homology analysis of strains were performed by Spa geno-typing.Results All 12 MRSA-infected patients were susceptible to multidrug-resistance bacterial infection,5 cases of MRSA infection occurred during this hospitalization.Detection of specimens from health care workers and envi-ronment were all negative;Spa gene of all 12 MRSA isolates was type t 030 ,which was the main epidemic strain in Asia;Spa gene of Staphylococcus aureus isolated from nurses’noses was type t1425 .Conclusion The assumption of MRSA spread among health care workers aren’t supported by the epidemiological investigation results,genotypes of 12 MRSA isolates are identical,but the result of gene typing can’t be as the evidence of homology of infection ;patients at high risk for MRSA infection should be screened as early as possible,early contact isolation should be performed,so as to prevent and control the occurrence of HAI.

ObjectiveTo observe β cell function in newly diagnosed diabetic patients with ketosis before and in remission period and evaluate its classification and predictive value.MethodsA total of 206 patients newly diagnosed as diabetic ketosis who had been treated with intensive insulin therapy in our hospital and entered in the honeymoon after the withdraw of insulin therapy were followed for 36 months from onset of diabetes.They were divided into two groups of type 1 and type2 diabetes ( group A and B),according to the dependence or independence on insulin treatment. The β cell function of the two groups before and in remission period was compared by oral glucose tolerance test (OGTF).β cell function was measured with the AUC of insulin and C-peptide and homeostatic model assessment β-cell function (HOMA-β),while homeostatic model assessment insulin resistant (HOMA-IR) for insulin resistant.The duration of the honeymoon and the change of insulin and C-peptide curve before and in honeymoon were also observed.ResultsThe AUC of insulin and C-peptide,the HOMA-β and the HOMA-IR before and after the intensive insulin treatment were lower in group A than that in group B [ before the insulin treatment:(10.18 ±2.36)mIU · h · L-1 vs (20.28 ±6.89)mIU · h · L-1,(1.56 ±0.53) μg · h · L-1 vs (3.75 ±0.67) μg · h · L-1,3.68 ± 1.08 vs 18.20 ±6.59,1.22 ±0.49 vs 3.06 ± 1.54,respectively;after the insulin treatment:(29.86 ± 8.65 ) mIU · h · L-1 vs (93.35 ± 19.42 ) mIU · h · L-1,( 3.99 ± 0.79 )μg · h · L-1 vs ( 12.54 ±3.83) μg · h · L-1,8.50 ±2.46 vs 56.17 ± 19.42,0.63 ±0.56 vs 1.42 ±0.78,respectively ].The duration of the honeymoon in group A was significantly shorter than in group B [ (7.9 ±5.2) months vs (20.9 ± 9.9 ) months ].In oral glucose insulin and C-peptide release test,the peak of insulin and C-peptide releasing curve in group A was brought forward by a half to 1 hour after intensive treatment while delayed in group B by 1 or 2 hours.The releasing peak of insulin and C-peptide in group A was less than two folds of the basic value,while four to ten fold of the basic value in group B.The positive ratio of glutamic acid decarboxylase antibody,insulin autoantibody and insular cellular antibody in group A and group B were 21.2％ vs 4.8％,18.1％ vs 3.3％,9.2％ vs 10.6％,respectively.ConclusionsOf all the patients newly diagnosed as diabetes ketosis who had entered into the honeymoon after intensive insulin therapy,91％ were type 2 diabetes.Inferior β cell function before insulin therapy,weaker remission after insulin therapy and shorter duration of remission period suggest the classification of type 1 diabetes.

Objective To establish a method for reducing the dose to the eye lens of interventional staff,and provide the data basis for improving radiological protection measures.Methods One piece of interventional equipment coupled with conventional auxiliary protective devices and two types of common neural interventional procedures were selected to monitor 46 and 35 procedures before and after the device modification.The doses to the eye lens of staff were measured with direct-reading dosimeters for analysis of dose trends.Results After modification of the devices,the average dose to the left eye lens decreased from (9.71 ±10.86) to (3.23 ±5.59) μSv for the first operator,from (9.51 ± 12.34) to (0.68 ± 0.78) μSv for the second in cerebral angiography;whereas the dose decreased from (14.83 ± 19.13) to (4.17±4.59) for the first operator and from (14.12±21.76) to (1.23 ±1.57)μSv for the second in embolization procedure,respectively.The left eye lens doses measured before and after the modification showed significant difference (U =-2.760,-2.467,-1.967,-2.655,P ＜0.05).Conclusions The modification of the auxiliary radiological protective devices may effectively reduce the dose to the eye lens dose.This method was shown to be feasible for the improvement of radiological protection of interventional staff.
