0.05). Conclusions The distribution of the RMSh was widely ranged among hyperopic children,and some children expressed higher value of RMSh. As the pupil diameter got larger,the RMS value of HOA significantly increased. Vertical coma was more frequent dominating type of HOA among hyperopic children. (Ophthalmol CHN ,2006,15: 187-190)

Objective To compare the effects of rib internal fixation and thoracic external fixation in treatment of traumatic flail chest. Methods Eighty six cases of traumatic flail chest with multiple injuries,admitted to hospital from January 2006 to June 2009 ,were recruited into the study and divided into rib internal fixation and thoracic external fixation groups randomly. The clinical data were analyzed retrospectively. Rib internal fixations with Ti-Ni shape memory alloy embracing connector were performed in internal-fixation group(n = 45) and thoracic external fixations were performed in external-fixation group(n = 41). The outcomes were compared between the two groups. Results No patient in internal-fixation group developed chest wall deformity,while 19 patients in external-fixation group had chest wall deformity left. The mean times of hospital stay([ 15. 1 ± 1.8]d vs [22. 9 ±2. 8]d,t = - 15. 724,P ＜0. 01) ,ICU stay([5.7 ± 1.5]d vs [ 14. 4 ±2. 9]d,t =- 17.711, P ＜ 0. 01), and mechanical ventilation([ 3.9 ± 1.5 ] d vs [ 1 1.6 ± 2. 3 ] d, t = - 17. 256, P ＜ 0. 01),in internal-fixation group were significantly shorter than those in external-fixation group. The occurrence rate of respiratory complications (including pulmonary inflammation and (or) atelectasis and (or) respiratory failure)in internal-fixation group was significantly lower than those in external-fixation group(35.6% vs. 70. 7% ,x2 =10.641,P ＜ 0.01). Followed-up data of three months after discharge showed that the pulmonary function parameters, such as total lung capacity([ 89. 5 ± 3. 1 ] % vs. [ 79. 1 ± 5. 1 ] %, t = 11. 705, P ＜ 0. 01), forced vital capacity([ 80. 2 ± 2. 8 ] % vs. [ 69. 8 ± 3. 8 ] % ,t = 14. 241 ,P ＜0. 01) ,forced expiratory volume in the 1st second ([74.8 ±4.4]% vs. [71.9 ±3.6]% ,t =3.201,P ＜0.01),peak expiratory flow ([82.8 ±4.4]%vs. [79. 8 ±4. 9]% ,t =2. 885,P ＜0. 01) and forced expiratory flows at 75% of the vital capacity( [68.2 ±2. 2] % vs. [61.9 ± 2. 9 ]%, t = 11. 286; P ＜ 0. 01) were significantly higher in internal-fixation group than those in external-fixation group. Conclusion Rib internal fixation for traumatic flail chest can quickly correct chest wall deformity, stabilize thoracis and eliminate paradoxical chest wall movement. Patients accepted this treatment have a shorter therapy process during the intensive care unit and hospital stay, less pulmonary complications. They also show less long-term restrictive pulmonary functions impairment, when compared to the patients in the thoracic external fixation group. Rib internal fixation with Ti-Ni shape memory alloy embracing connector is a simple and effective therapy.

Objective To understand the characteristics of molecular epidemiology of enterovirus 71(EV71) in children with hand, foot and mouth disease (HFMD) in Shanghai area during the first half year of 2009. Methods Seventy-three throat swabs and 38 stool samples were collected from 95 hospitalized children with clinical diagnosis of HFMD in Children's Hospital of Fudan University during April to May 2009. TaqMan real-time reverse transcription-polymerase chain reaction (RT-PCR) and nest RT-PCR were used to detect EV71 VP1, followed by gene sequencing analysis. Results Six of the 73 throat swabs were EV71 positive with the detection rate of 8.2%. In the 38 stool samples, 24 were EV71 positive with the detection rate of 63.2%. Twenty-eight nested RT-PCR positive samples were sequenced and the genetic analysis showed that 27 were C4 subtype,which were absolute dominant strain and the other one was C2 subtype. The isolated strain from a fatal case was C4 subtype and there was no obvious mutation found in VP1 region. Conclusions EV71 is an important pathogen in HFMD children in Shanghai area during April to May 2009. C4 subtype strains are absolutely dominant, and accompanied by epidemic strains of subtype C2.

Objective To investigate the serum levels of soluble CD23 ( sCD23 ) and thrombopeietin (TPO) in chronic lymphocytic leukemia (CLL) and their correlation with other prognostic factors. Methods The serum levels of sCD23 and TPO of 25 CLL patients were detected with enzyme linked immunosorbent assay. Flow cytometry was employed to determine the expression of CD38 and ZAP-70 protein. Results TPO level in CLL patients was significantly higher than that in normal controls 67.22 - 1881.77 ng/L and 70. 29 - 147. 98 ng/L respectively, P =0. 003. sCD23 level in CLL patients was significantly higher than that in normal controls 129. 80-405. 31 U/ml and 0. 65 -32. 99 U/ml respectively, P =0. 000. TPO level was significantly correlated with Binet stage and CD38 expression. Patients in stage B and C had higher level of TPO than those in stage A 140. 57 -457.48 ng/L and 121.92 - 163.83 ng/L respectively, P =0.014,while TPO level was higher in patients with higher CD38 expression than in patients lower CD38 expression 113.23- 199. 10 ng/L and 141.34 -454. 92 ng/L respectively, P = 0. 033. No significant correlation of sCD23 and TPO levels with ZAP-70 protein, sex, age, peripheral lymphocyte count and lactate dehydrogenase were observed. Conclusion Serum TPO level might be a prognostic factor in CLL.

Cartilage antuumor component (CATC) was isolated from a 1 mol/L guanidine hydrochloride extract of bovine cartilage by acetone fractioned precipitation and superfiltration. Using human skin fibroblasts as a normal control, it was demonstrated that CATC inhibited the DNA synthesis of Hela, QGY7703 tumor cell lines and bovine artery endothelial cells, but accelerated the normal cells, when the concentration was below 1250 ?g/ml. At the concentration of 5 000 ?g/ml, CATC inhibited the two cell lines. With human tumor stem cell assay, CATC inhibited the stem cell growth of Hela and QGY7703 cell lines. These suggest that CATC has the effects of inhibiting angiogenesis and tumor cells.

Objective To explore the changes of plasma brain natriuretic peptide(BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP)of sepsis combined with myocardial injury in newborns.Methods According to neonatal sepsis treatment program,45 cases of sepsis newborns in NICU of the Second Hospital in Lanzhou University from Jul.2007 to Jun.2008 were collected.According to the myocardial injury diagnostic criteria,45 cases neonatal sepsis were divided into myocardial injury group(n=22) and non-myocardial injury group(n=23).Myocardial injury group was also divided into congenital heart disease group and non-congenital heart disease group accor-ding to echocardiography.At the same time,30 healthy newborns were collected as healthy control group.Every newborns were tested the level of plasma BNP,NT-proBNP,creatine kinase-MB(CK-MB) and cardiac-troponin I (cTnI).Results There were significant difference between myocardial injury group,non-myocardial injury group and healthy control group in the levels of plasma BNP,NT-proBNP,CK-MB and cTnI,those in congenital heart disease group were higher than those in non-myocardial injury group and the healthy control group(Pa0.05).Conclusions BNP and NT-proBNP can be early used to diagnose myocardial injury and heart failure of neonatal sepsis associated with CK-MB and cTnI.In NICU,infants with sepsis should normally test BNP and NT-proBNP in order to early diagnose myocardial injury of neonatal sepsis.

Objective:To investigate the relationship between serum homocysteine (HCY), folate (FOL) and methylenetetrahydrofolate reductase (MTHFR) C677T, A1298C gene polymorphism in patients with type 2 diabetic nephropathy (DN).Methods:A total of 161 patients with type 2 diabetes diagnosed in Jiangsu Shengze Hospital between January 2017 and December 2018, including 81 DN (41 males, 40 females; age: (61.5±14.2) years), 80 diabetic mellitus without nephropathy (DM; 42 males, 38 females, age: (57.7±10.8) years), and 77 normal controls (NC; 39 males, 38 females, age: (58.2±16.3) years) were retrospectively analyzed. The serum levels of HCY and FOL were detected by enzyme circulation and electrochemiluminescence respectively. TaqMan genotyping technique was used to detect MTHFR 677T&A1298 gene polymorphism. The serum levels of HCY and FOL were compared with one-way analysis of variance (the least significant difference t test), and the distribution differences of MTHFR gene were analyzed by χ2 test. Results:The difference of HCY level among DN, DM and NC groups was significantly different ((19.76±7.81), (15.62±5.01) and (8.09±3.74) μmol/L; F=81.738, P<0.001). The FOL level among the 3 groups was also significantly different ((12.18±3.01), (13.50±2.71) and (15.43±2.95) μg/L; F=26.978, P<0.001). The frequencies of 677T allele (51.2%, 83/162), 677TT/1298AA genotype (25.9%, 21/81) in DN group were significantly higher than those in DM (33.1%, 53/160; 11.2%, 9/80) and NC (33.8%, 52/154; 10.4%, 8/77) groups ( χ2 values: 10.821, 9.099, both P<0.05), but the 1298C allele frequency was not significantly different among the 3 groups (21.6%(35/162, DN) vs 16.9%(27/160, DM) vs 18.2%(28/154, NC); χ2=1.269, P>0.05). The levels of HCY and FOL in individuals with 677TT/1298AA genotype were significantly higher than those in individuals with other genotypes ( F values: 12.955, 15.504, all P<0.05). Conclusion:The abnormal metabolism of HCY and FOL caused by MTHFR C677T&A1298C gene polymorphism may be the genetic risk factor of DN.
