Objective To investigate the optimal surgical timing for rib internal fixation.Methods The clinical data of 143 patients with rib fracture were retrospectively analyzed.The patients were divided into early phase fixation group (62 cases) and late phase fixation group (81 cases) according to the time from trauma to internal fixation.The ratio blood lose and body surface area,pulmonary complications and the changes of C reactive protein level before and 5 days after operation were recorded and compared.Results All the patients were healing.The median C reactive protein before operation in late phase fixation group was 45 mg/L,in early phase fixation group was 23 mg/L,there was statistical difference (P ＜ 0.01).The ratio blood lose and body surface area in early phase fixation group was (334.19 ± 37.53) ml/m2,the rate of pulmonary complications was 22.6％(14/61),in late phase fixation group was (438.99 ± 55.24) ml/m2 and 38.3％ (31/81),there were statistical differences (P ＜ 0.01 or ＜ 0.05).The median C reactive protein 5 days after operation in early phase fixation group was 189 mg/L,in late phase fixation group was 258 mg/L,there was statistical difference (P ＜ 0.05).Conclusion Early phase (72 hours) rib internal fixation is expected to reduce patient trauma of systemic reactions,reduce the incidence of bleeding and pulmonary complications.

Objective To study the immunodiagnostic potential of recombinant membrane protein Tetraspanin 2 of Schistosoma japonicum(rSjTsp2) as a diagnostic antigen. Methods The rSjTsp2 was expressed and purified as an antigen used in indirect ELISA to detect specific serum antibody against Schistosoma japonicum of rabbits that at different stages of infection, and the results were compared with those of ELISA using natural antigen (AWA) as antigen. Results The sensitivities of rSjTsp2-ELISA were 75.4% (46/61),77.6% (45/58) and 81.5% (44/54), respectively, 2, 4, 6 weeks after rabbits were infected with Schistosoma japonicum, meanwhile the sensitivities of AWA-ELISA were 68.9% (42/61),86.2% (50/58) and 88.9% (48/54), respectively. The sensitivity difference of two methods was not significant statistically (x2 = 0.652, 1.454,1.174, all P ＞ 0.05).Conclusions The rSjTsp2 is expressed successfully in vitro, and rSjTsp2 recombinant protein expressed in prokaryotic system has a certain application potential in immunodiagnosis.

Objective To investigate the effects of different duration of sevoflurane anesthesia in the neonatal period on the long?term cognitive function and hippocampal synaptic plasticity in rats. Methods Twenty?four pathogen?free healthy Sprague?Dawley rats of both sexes, aged 7 days, weighing 12-16 g, were divided into 3 groups ( n=8 each) using a random number table: control group ( group C) , sevoflu?rane anesthesia for 2 h group ( group S1 ) , and sevoflurane anesthesia for 6 h group ( group S2 ) . Group S1 and group S2 inhaled 2% sevoflurane for 2 and 6 h, respectively. Morris water maze test was performed at 30 days after the end of anesthesia ( postnatal day 37) to assess the cognitive function. After the end of the test, the rats were sacrificed, and hippocampi were isolated for determination of the expression of brain?de?rived neurotrophic factor ( BDNF) , postsynaptic density?95 ( PSD?95) and synapsin 1 in hippocampal tis?sues by Western blot. Results Compared with group C, the escape latency on 4th and 5th days of the test in group S1 and on 2nd-5th days of the test in group S2 was significantly prolonged, and the frequency of crossing the original platform was significantly decreased, and the time of staying at the platform quadrant was significantly shortened in S1 and S2 groups, the expression of BDNF, PSD?95 and synapsin 1 in hipp?ocampal tissues was significantly down?regulated in group S2 (P<0?05), and no significant change was found in the expression of BDNF, PSD?95 and synapsin 1 in hippocampal tissues in group S1 ( P>0?05) . Compared with group S1 , no significant change was found in the escape latency and frequency of crossing
the original platform (P>0?05), the time of staying at the platform quadrant was significantly shortened, and the expression of BDNF, PSD?95 and synapsin 1 in hippocampal tissues was significantly down?regula?ted in group S2 ( P<0?05) . Conclusion Short?time and long?time sevoflurane anesthesia both can induce long?term cognitive dysfunction in the neonatal period, and the severity is aggravated with prolonged anes?thesia; the partial mechanism is related to inhibition of the synaptic plasticity of hippocampal neurons of rats.

Objective To investigate the influence of a multifaceted stroke telehome-care (THC) on extremities function, activities of daily living (ADL) and quality of life in stroke patients with hemiplegia. Methods A total of 52 stroke survivors in department of neurology were randomized to the THC intervention or usual care. The patients in the control group received conventional care, while those in the intervention group were additionally given a THC program over 3 months. The THC intervention includes motor imagery and adaptive strategies. Data collection was undertaken using the Fugl-Meyer Motor Assessment Scale (FMA), the Barthel Index (BI), the Stroke Impact Scale (SIS) at baseline, 3 months, and 6 months. Results At baseline, the scores of FMA, BI, and SIS in the intervention group were 53.62 ± 23.52, 54.04 ± 17.44, 179.96 ± 28.51, and while the scores of the control group were 50.96 ± 19.52, 49.46 ± 15.09, 169.23 ± 28.48. There were no pre-existing differences on any scale between the two groups (t=0.443, 1.012, 1.358, P > 0.05). At 3 months, the scores of FMA, BI, SIS in the control group were 53.54 ± 17.45, 50.77 ± 14.47, 76.19 ± 27.78, and were significantly lower than 78.38 ± 12.54, 74.62 ± 11.22, 228.54±22.63 in the THC group (t=5.895, 6.641, 7.449,P<0.01). At 6 months, the scores of FMA, BI, SIS in the control group were 57.88±17.89, 59.08±13.85, 183.92±26.56, and were significantly lower than 90.58 ± 9.60, 86.54 ± 9.88, 252.19 ± 20.10 in the THC group (t=8.211, 8.233, 10.451, P < 0.01). Conclusions A telehome-care program that provide distance training and education of disabled persons resulted in greater improvements in physical functioning, ADL and quality of life.

Objective To explore the diagnosis and curative effect of phenylketonuria(PKU) in Gansu.Methods Fifty-nine thousand nine hundred infants and 118 borderline cases were screened from Oct.1999 to Dec.2006.Three drops of venous blood was collected from the exterior or interior part in the heel,and trickled the venous blood onto the specialized filter paper,which could be formed into 3 bloodstains with the diameter of 0.8-1.0 cm.Phenylalanine(phe) was detected by chemiluminescence method,and PKU was screened by the PKU standard of diagnosis.Infants with PKU had been given low phe food.During the treatment,phe level,physical development and intellectual development were measured regularly.Patients′ body weight,height and head circumference were measured once 1 month.Patients′ intellectual quotient(IQ) were measured every half year(IQ was analyzed by Gesell test).Results were analyzed by SPSS 11.0 software for t test.Results In total,93 patients with PKU were diagnosed and treated.Thirty-six cases were identified by neonatal screening before 3 mouths old.Mental retardation was found in 57 cases before 6 years old.After treatment with low-phe diet,the follow-up for early-treated patients revealed that their physical and mental development were normal,and height,weight and head circumference were in the normal amplitude,and the results of IQ was(92?12)scores.In later treated patients,abnormal behaviors were significantly improved and their developmental quotients were elevated.Before treatment,Gesell value was(57?20)scores;after 12-18 months treatment Gesell value was(70?20)scores.The difference was significant(t=1.705 P
